Electronic components that have been labeled in the electronic component labeling equipment (EDLE) (see earlier invention 1) are tested by the electronic component testing equipment (EDTA) in the state loaded in the loading tray (see earlier invention 2). Then, the loading tray, which has been tested for the loaded electronic components, is moved to the Electronic Components Sorting Equipment (EDSE).

Therefore, the Electronic Components Sorting Equipment (EDSE) accepts the loading tray from the Electronic Components Testing Equipment (EDTE) in the front end. In addition, the electronic component sorting equipment (EDSE) sorts the electronic components according to the test result while unloading the electronic components from the received loading tray and loads them in the customer tray.

<Description of the loading tray>

Figure 2 is a top perspective view of the loading tray (LT), Figure 3 is a bottom perspective view of the loading tray (LT).

The loading tray (LT) is provided with 16 _{pairs of gripping members (PE 1} , PE _{2) forming a pair with each other.} In addition, guide holes GH ₁ and GH ₂ are formed in the gripping members PE ₁ and PE _2.

In addition, since the gripping members (PE ₁ , PE _{2 ) are supported by the springs (S 1} , S ₂ ) as in FIG. 4, the elastic force in the direction facing each other between the gripping members (PE ₁ , PE _{2) forming a pair} This works. Accordingly, the electronic component ED is gripped between the gripping members PE ₁ and PE _{2 forming a pair.}

In order to load or unload the electronic component (ED) into the loading tray (LT) as necessary, a _{gap between the pair of gripping members (PE 1} , PE ₂ ) must be widened. To this end, in a pair, as referred to in (a) is also very exaggerated five guide hole (GH _1, GH ₂₎ between the distance (L ₁₎ the spacing between wider than the mutual movement in the pair having the (L ₂₎ pin (MP ₁ , MP ₂ ) is required. That is, when the paired movable pins (MP ₁ , MP ₂ ) are inserted into the paired guide holes (GH ₁ , GH ₂ ), the paired gripping members PE ₁ , PE ₂₎ electronic component (ED), the amount holding members (PE _1, PE ₂₎ entering or both gripping members (PE _1, PE ₂₎ can allow stacking tray (LT) to be drawn out from between between by spacing the flaring by L ₂ between the Is opened. Of course, moving the paired pin (MP _1, MP ₂₎ the fall from the guide hole (GH _1, GH _2), holding members (PE _1, PE ₂₎ the interval narrowing As between the holding members (PE _1, PE ₂₎ As a result, the electronic component ED is held.

In addition, wide fixing holes FH having a square shape are formed on both left and right sides of the loading tray LT, and alignment holes SH are formed at both ends of the rear surface of the loading tray LT. The fixing hole FH and the alignment hole SH will be described later in the related part.

For reference, reference numeral ED in FIGS. 4 and 5 may be a solid-state-drive (SSD), which is a type of electronic component.

<Description of the customer tray>

The customer tray is provided to load electronic components (ED) that have been moved from the loading tray (LT).

6 is a schematic plan perspective view of the customer tray CT, and FIG. 7 is a bottom perspective view of the customer tray CT.

The customer tray CT has a plurality of insertion grooves IH into which the electronic component ED can be inserted. In addition, gripping spaces HS that go toward the center line O are formed at the lower front and rear ends of the customer tray CT. Further, on the bottom surface of the customer tray CT, matching holes AH are formed in each of the vicinity of the square corners.

Regarding the above gripping space (HS) and matching hole (AH), it will be described later in the related part.

<Logistics of the loading tray (refer to the solid arrow in Fig. 8)>

The loading tray LT, which came from the electronic parts testing equipment (EDTE) in the front part to the electronic parts sorting equipment (EDSE) _{, moves backward along the first path C 1} and stops at the unloading position (ULP). At the unloading position ULP, the loading tray LT, in which the unloading of the electronic component is completed, is continuously _{moved backward along the first path C 1} to move to the movement end point MEP. The empty loading tray LT located at the moving end point MEP is transferred to the moving start point MSP _{of the second path C 2.} And the empty loading tray (LT) at the moving start point (MSP) is _{moved to the transfer point (PBP) along the second path (C 2} ), and then sent to the electronic component testing equipment (EDTE) in the front end.

<Logistics of customer tray (refer to the dotted arrow in Fig. 8)>

The logistics of the customer tray (CT) is the logistics of the customer tray (CT) for loading electronic parts (ED) that are determined to be defective and the logistics of the customer tray (CT) to load electronic components (ED) that are determined to be good. Is divided.

1. Logistics of customer tray (CT) for loading good products

First, the operator positions the empty customer tray CT to the supply position (SPP).

Customer tray (CT) in the feed position (SPP) is moved to the first classification position (SP1) of the left (indicated by arrows a _1). At this time, the moving direction of the customer tray CT is perpendicular to the moving direction of the loading tray LT on _{the first path C 1} or the second path C _2. Of course, the first path (C ₁₎ or the customer tray from the lower side of the second path (C ₂₎ and so that it does not conflict, the first path (C ₁₎ and a second path (C ₂₎ movement of the customer tray (CT) (CT) is moved. And the customer tray (CT) is raised to the upper branch (SP1t) on a first classification position (SP1) (see arrow a _2).

Is complete, the customer tray (CT) of the electronic component mounting (ED) a non-defective product in the upper branch (SP1t) is horizontally moved to the lowered position (DWP) of the rear (see arrow a _3). At this time, the moving direction of the customer tray CT is parallel to the moving direction of the loading tray LT on _{the first path C 1} or the second path C _2.

Customer tray in a lowered position (DWP) (CT) is lowered (see arrow a _4).

Lowered customer tray (CT) is moved to the discharge position (DCP) to the right (see arrow a _5). At this time, the moving direction of the customer tray CT is perpendicular to the moving direction of the loading tray LT on _{the first path C 1} or the second path C _2. In addition, the customer tray CT, which is located at the discharge location (DCP) with the good electronic parts (ED) filled, is discharged to the outside of the electronic parts sorting equipment (EDSE) by the operator.

2. Logistics of customer tray (CT) to load defective products

The operator places the empty customer tray (CT) in the supply and demand position (SDP).

Customer tray (CT) in the supply position (SDP) is moved to the second classification position (SP2) to the left (see arrow b _1). At this time, the moving direction of the customer tray CT is perpendicular to the moving direction of the loading tray LT on _{the first path C 1} or the second path C _2. And the customer tray (CT) is raised to the upper branch (SP2t) on a second classification position (SP2) (see arrow b _2).

Is complete, the customer tray (CT) of the electronic component mounting (ED) defects in the upper branch (SP2t) is lowered (see arrow b _3). The lowered customer tray (CT) is returned to the supply and demand position (SDP) on the right. At this time, the moving direction of the customer tray CT is perpendicular to the moving direction of the loading tray LT on _{the first path C 1} or the second path C _2. And repositioned in the defective electronic component supply position (SDP) to the state (ED) it is filled (see arrow b ₄₎ the customer tray (CT) is discharged to the outside of the electronic component classification equipment (EDSE) by an operator.

In this embodiment, the supply path of the empty customer tray CT for loading good products and the discharge path of the customer tray CT filled with good products are different. However, the supply path of the empty customer tray CT for loading defective products and the discharge path of the customer tray CT filled with defective products overlap. This reason is generally related to the fact that the number of electronic parts determined as good products is large and the number of electronic parts determined as defective products is small. In order to process a large number of good products, it is implemented to place a plurality of empty customer trays CT stacked in a vertical direction at the supply location (SPP). Therefore, it is difficult for the customer tray (CT) filled with good products to return to the supply position (SSP). However, since it is implemented to place only one customer tray (CT) in the supply/demand location (SDP) in order to process a small number of defective products, the customer tray (CT) filled with defective products can be returned to the supply/demand location (SDP).

Therefore, if the processing capacity is not considered, the distribution of the customer tray (CT) for loading good products can also be applied and implemented to overlap the supply path and the discharge path. Conversely, if a lot of defective products are generated in the process, the supply path and the discharge path of the customer tray (CT) for loading the defective products may be applied differently from each other.

<Description of the picker device>

12 is a schematic perspective view of the picker device 210.

The picker device 210 includes an electronic component gripper 211, a gripper lift 212, a first horizontal mover 213 and a second horizontal mover 214.

The electronic component gripper 211 includes a pair of gripping members 211a-1 and 211a-2 and a space adjuster 211b.

The pair of gripping members 211a-1 and 211a-2 grips or grips the electronic component ED by narrowing or spreading the gap between each other by the gap adjuster 211b ( _{refer to arrows d 1} and d _2). Release. Each of the pair of gripping members 211a-1 and 211a-2 includes an adjustment cylinder MC and an advancing and retreating member AR that advances and retreats by the adjustment cylinder MC. In addition, the gripping surface GF of the advancing member AR has a'C' shape that is approximately opened in a'V' shape (refer to the excerpt). This is because the thickness standard of the substrate (CB) constituting the electronic component (ED) is the same, but the thickness standard of the other parts (TD) mounted on the substrate (CB) may vary. It is to make it possible. In other words, the point in contact with the substrate (CB) is flattened by the same width (D) as the thickness (D) of the substrate (CB) so that the substrate (CB) can be gripped, and the rest of the part is opened so that other parts (TD) ) Thickness change is considered.

The gap adjuster 211b narrows or widens the gap between the pair of gripping members 211a-1 and 211a-2 in the front-rear direction. Two screw wires SL1 and SL2 are formed on the transmission shaft DS of the space controller 211b, and both screw wires SL1 and SL2 are formed in opposite directions based on the center of the entire transmission shaft DS. have. Therefore, when the transmission shaft DS is rotated by one driving motor DM, the coupling portions CP1 and CP2 of the pair of gripping members 211a-1 and 211a-2 respectively coupled to both screw lines SL1 and SL2 ) Is forced in opposite directions to move the pair of gripping members 211a-1 and 211a-2 in opposite directions, so that the gap between the pair of gripping members 211a-1 and 211a-2 can be adjusted. have. Therefore, even if one drive motor DM is used, the electronic component ED can be held by the pair of gripping members 211a-1 and 211a-2.

Of course, it is also possible to hold the electronic component ED or release the grip by only the spacer 211b. However, when the electronic component ED is accurately gripped by only the spacer 211b, there is a risk of damage due to the characteristics of the electronic component ED, which is less accurate. Therefore, in the present embodiment, each of the pair of gripping members 211a-1 and 211a-2 is further provided with an adjustment cylinder MC and an advancing and retreating member AR that advances and retreats by the adjustment cylinder MC. Therefore, after firstly adjusting the gap between the pair of gripping members 211a-1 and 211a-2 by the gap adjuster 211b, the gap between the advancing and retreating members AR is secondarily adjusted by the adjustment cylinder MC. It is implemented to hold the electronic component (ED) by narrowing the gap. In this way, by holding the electronic component ED in two steps by the spacer 211b and the adjustment cylinder MC, it is possible to prevent damage to the electronic component ED. In addition, in the case of termination of the electronic component (ED), the adjustment cylinder (MC) operates first, and then the interval controller (211b) is operated.

If an accurate standard of the electronic component ED is guaranteed, it is possible to sufficiently omit either the spacer 211b or the adjustment cylinder MC.

The first horizontal mover 213 moves the electronic component gripper 211 in the front-rear direction.

The second horizontal mover 214 moves the electronic component gripper 211 in the left and right directions.

The operation of the picker device 210 having the above configuration will be described.

When the electronic component gripper 211 grips the electronic part ED from the loading tray LT at the unloading position ULP and then rises by the gripper elevator 212, the first horizontal mover 213 and The second horizontal mover 214 operates to move the electronic component gripper 211 to the first sorting position SP1 or the second sorting position SP2. In addition, the gripper lift 212 lowers the electronic component gripper 211 so that the customer tray located at the upper point SP1t of the first sorting position SP1 or the upper point SP2t of the second sorting position SP2 ( LT). Subsequently, the electronic component gripper 211 lifts after releasing the gripping of the electronic component ED. After that, the electronic component gripper 211 moves to the unloading position ULP and repeats the above-described operation.

Meanwhile, depending on implementation, a plurality of pairs of gripping members may be provided in the electronic component gripper. Furthermore, the gripping members of different pairs may be implemented to lift and descend independently of each other. In addition, when a plurality of pairs of gripping members are provided, the plurality of gripping members may be implemented to independently grip the electronic component by selectively operating the adjustment cylinders. In addition, by setting the stroke distance of each of the adjustment cylinders differently, it may be implemented to hold electronic components of different sizes.

For reference, a sensor for detecting the electronic component ED or an aligner for aligning the position of the electronic component ED may be further provided on the gripping members 211a-1 and 211a-2.

The open plate 311 is provided to be elevating and has 16 pairs of moving pins MP ₁ and MP ₂ as mentioned in FIGS. 4 and 5 on its upper surface. This open plate 311 is disposed between the pair of moving belts 114a and 114b and at the unloading position ULP.

The cylinder 312 raises and lowers the open plate 311.

The aligner 313 is provided with a pair coupled to both sides of the open plate 311, and has an alignment pin (313a) capable of aligning the loading tray (LT) in the correct position.

Therefore, when the opening plate 311 is raised by the cylinder 312, the alignment pins 313a of the aligner 313 are first inserted into the alignment holes SH of the loading tray LT, thereby correcting the loading tray LT. After aligning to the original position, which is the unloading position (ULP), the spring 313b is compressed and its rise is stopped. Then, 16 pairs of moving pins (MP ₁ , MP _{2 ) are inserted into the 16 pairs of guide holes (GH 1} , GH ₂ ) in the pajama members (PE1, PE2) of the loading tray (LT), and the loading tray (LT) Is opened. Of course, when the opening plate 311 descends, the loading tray LT is closed. With respect to the opening of the loading tray LT, since it has already been described with reference to FIGS. 4 and 5 in the description of the loading tray LT, a more detailed description will be omitted.

For reference, when the open plate 311 rises, the loading tray LT may be raised together. Therefore, it is preferable that a separate fixing device is implemented to prevent the rising of the loading tray LT by hanging the lower surface or the upper end of the loading tray LT forming the fixing hole FH of the loading tray LT. Of course, considering the possibility of interference with the picker device 210 working above the loading tray LT, it is more preferable that the fixing device is implemented to hang the lower surface forming the fixing hole FH of the loading tray LT. And, if the fixing member is implemented to hang the lower surface forming the fixing hole (FH), it will be provided with a fixing member capable of advancing and retreating in the left and right direction. In this case, the fixing member can be inserted into or removed from the fixing hole FH by advancing and retreating in the left and right direction.

<Description of the stop device>

14 is a schematic perspective view of the stopping device 410.

The stop device 410 stops the movement of the loading tray LT that has been moved to the unloading position ULP along _{the first path C 1.} This stopping device 410 includes a stopper member 411 and an actuator 412.

The stopper member 411 may be erected or laid down. If the stopper member 411 is erected (refer to the dotted line), the movement of the loading tray LT is blocked and stopped, and when the stopper member 411 is laid down, the loading tray LT may be continuously moved. It is preferable that the stopper member 411 has a contact end 411a of a non-metal material (for example, a material of synthetic resin such as urethane) for the purpose of absorbing shock while being a non-conductor in order to prevent each other from impact damage with the loading tray (LT). Do. Since the contact end 411a is sufficient to be provided in a portion in contact with the loading tray LT, it can be applied in various forms.

The actuator 412 erects or lays the stopper member 411.

When the loading tray (LT) is stopped at the unloading position (ULP) by the stop device 410 as described above, the operation of the first moving device 110 is also stopped with a slight time difference, and the picker device 210 is opened. The device 310 is operated to unload the electronic component ED loaded in the loading tray LT. When all of the electronic components ED loaded in the loading tray LT are unloaded later, the stop state of the loading tray LT is released by the stop device 410. Then, the first moving device 110 operates again to move the loading tray LT from the unloading position ULP to the moving end point MEP.

For reference, the stop device having the configuration as shown in FIG. 14 is to stop the loading tray LT at the moving end point (MEP) _{of the first route (C 1 ) or the transfer point (PBP) of the second route (C 2 ).} In addition, it may be further provided. That is, the stopping device having the configuration as shown in Fig. 14 may be provided as many as necessary to stop the loading tray LT at the required position of _{the first path (C 1} ) or the second path (C _{2 ).} have.

The reason why the above stop device is required is that the first moving device 110 uses a conveyor belt as the moving belts 114a and 114b. In general, it is difficult with the current technology to erect a loading tray (LT) in a specific, precise position of a conveyor belt. So, in the position where the loading tray (LT) is to be stopped, a stop device is required at all.

In addition, the stopper member can be designed to rise from the bottom, but in this case, if the loading tray (LT) stops beyond the stop position, the stopper member may lift or damage the loading tray (LT). There may be an error or damage due to the presence of a surface that rubs against (LT). Therefore, as in the present embodiment, the stopper member 411 is preferably implemented to be erected or laid down by rotation.

<Description of the supply device, discharge device, and supply device>

15 is a schematic perspective view of the supply device 510.

The supply device 510 includes a drive motor 511, a drive pulley 512, a driven pulley 513, and moving belts 514a and 514b.

The driving motor 511 rotates the driving pulley 512 in the forward and reverse direction, and the driven pulley 513 rotates in conjunction with the driving pulley 512.

The moving belts 514a and 514b rotate cyclically with the driving pulley 512 and the driven pulley 513 as rotation return points.

The supply device 510 as described above moves the customer tray CT placed on the moving belts 514a and 514b from the supply position SPP to the first sorting position SP1 on the left. In addition, the customer tray CT placed on the moving belts 514a and 514b may be moved from the first sorting position SP1 to the supply position SPP by reverse rotation of the driving motor 511.

Of course, as in the first moving device 110, the supply device is also two feeders 510A and 510B arranged in series in the moving direction of the customer tray CT (in this embodiment, the left and right directions) as shown in FIG. ) Can be divided into. Of course, each of the first feeder 510A and the second feeder 510B includes a drive motor (DMA/DMB), a drive pulley (DPA/DPB), a driven pulley (PPA/PPB), and a moving belt (MBA/MBB). Includes. When the first moving device is divided into two feeders 510A/510B in this way, the drive motor DMA of the first feeder 510A and the drive motor DMB of the second feeder 510B are provided as shown in FIG. They can be located near the middle of each other. In addition, the arrangement structure of the two driving motors DMA and DMB has the advantage of securing design freedom because design interference with the first loading device 520 or the lifting device 530 to be described later can be avoided. In this embodiment, the first loading device 520 is disposed on the right side based on the center line (C) divided by half of the total length of the first moving device, and the lifting device 530 is located on the left side based on the center line (C). Is placed in Therefore, if the driving motors (DMA, DMB) are to be arranged skewed to the right or left, the difficulty of causing design interference between the driving motors (DMA, DMB) and the first loading device 520 or the lifting device 530 occurs. will be. This difficult point can be solved wonderfully by having the arrangement structure of the driving motors DMA and DMB as in Fig. 16.

In addition, when the first moving device is divided into two or more feeders and provided, for example, if the distance that the customer tray CT moves by one feeder is secured more than the length in the left and right direction of the customer tray CT, A customer tray CT waiting to be supplied to the first sorting position SP1 may be placed on the moving belt of the feeder on the right side except for the moving belt of the feeder on the far left. Therefore, even while the electronic parts sorting equipment (EDSE) is in operation, it becomes easier for the operator to supply the customer tray (CT) to the feeder on the right.

The discharge device 560 has the same configuration as the supply device 510 described above. However, the discharging device 560 serves to move the customer tray CT lowered by the lowering device 550 to be described later to the discharging position (DCP) on the right. Therefore, unlike the supply device 510, the discharge device 560 suffices to be implemented to move the customer tray CT only in the right direction through a forward rotation.

<Description of the 1st loading device and the 2nd loading device>

17 is a schematic perspective view of the first loading device 520.

The first loading device 520 includes a tray cart 521, a pair of tray support plates 522a and 522b mounted on the tray cart 521, and a pair of support plate elevators 523a and 523b.

The tray cart 521 may be withdrawn in the right direction by an operator or may be withdrawn in the right direction and then in the left direction.

A pair of tray support plates 522a and 522b are provided with the moving belts 514a and 514b of the supply device 510 interposed therebetween. Of course, in some cases, a pair of tray support plates may be provided outside the moving belt of the supply device. These tray support plates 522a and 522b may support the customer tray LT or release the support by lifting and lowering. For reference, the operator pulls out the tray cart 521 in the right direction to a certain extent, and then places a plurality of empty customer trays CT stacked in the vertical direction on the pair of tray support plates 522a and 522b. In this case, the tray support plates 522a and 522b may have loading guide members LG1 and LG2 facing each other at both ends of the customer tray CT in order to guide the loading of the customer tray CT in the correct position. Here, the top height of the loading guide member LG1 on the right side is higher by h than the top height of the loading guide member LG2 on the left side. This is because there may be a need to withdraw the customer tray CT to the right due to circumstances such as a case where the customer tray CT moved to the left after being supplied by the worker is incorrectly supplied. That is, when the moving belts 514a and 514b of the supply device 510 rotate in a reverse direction and the customer tray CT that has been moved in the left direction moves in the right direction, the tray support plates 522a and 522b must be in a lowered state. do. At this time, in order that the loading guide member LG2 at the left end does not interfere with the movement of the customer tray CT in the right direction, the upper end of the loading guide member LG2 at the left end is moved as shown in Fig. 18(b). It should be located below the upper portion of the belts 514a and 514b. In addition, the upper end of the loading guide member LG1 at the right end must be positioned higher than the upper portion of the moving belts 514a and 514b in order to prevent excessive right movement of the customer tray CT. Of course, depending on the implementation, the loading guide member LG2 at the left end may be omitted, and only one customer tray CT may be placed on the tray support plates 522a and 522b.

The support plate elevators 523a and 523b raise and lower the tray support plates 522a and 522b. The operation of the base plate elevators 523a and 523b is controlled by the control device 700. Of course, the control device 700 may be implemented to control the operation of the base plate elevators 523a and 523b with a separate command input by the operator, and the situation recognition through an automated detection function allows the base plate elevators 523a and 523b to be It may be implemented to control the operation.

The first loading device 520 having the above configuration will be described.

When an operator attempts to withdraw the tray cart 521 from the supply position SPP in the right direction, the support plate elevators 523a and 523b raise the tray support plates 523a and 523b. Accordingly, the tray support plates 523a and 523b are positioned above the moving belts 514a and 514b of the supply device 510 as referred to in the side view of FIG. 18A.

In the state (a) of Fig. 18, the operator pulls out the tray cart 521 in the right direction from the supply position SPP. Then, after placing a plurality of customer trays CT stacked in the vertical direction on the tray support plates 523a and 523b, the tray cart 521 is pushed to the original supply position SPP. Thereafter, the support plate elevators 523a and 523b are operated to lower the tray support plates 523a and 523b, so that the customer tray CT is moved to the moving belts 514a and 514b of the supply device 510 as shown in Fig. 18B. ). Accordingly, the customer tray CT is supplied to the supply device 510 by the first loading device 520. And when the customer tray (CT) is moved to the first sorting position (SP1) by the operation of the supply device 510, the operator pulls out the tray cart 521 to receive a plurality of new customer trays (CT) support plate 523a, After loading on 523b), the tray cart 521 is pulled in. Accordingly, the customer trays (CT) can be arranged in parallel at the first sorting position (SP1) and the supply position (SPP) on both left and right sides, and the customer tray (CT) is continuously operated even while the electronic parts sorting equipment (EDSE) is in operation. As supply becomes possible, the utilization rate can be improved. That is, the supply location (SPP) can be used as a standby location of the customer tray (CT). Of course, in the discharge part of the customer tray (CT), the customer tray (CT) can be located in parallel at the lowering position (DWP) and the discharge position (DCP), and in this case, the discharge position (DCP) is the customer tray to be discharged ( CT) can be used as a waiting position.

In addition, a slide pack configuration may be added to the front and rear sides of the tray cart 521 for smooth withdrawal or retraction of the tray cart 521. By adding the slide pack configuration, the movement of the tray cart 521 is guided, and design interference with other components can be prevented through space saving.

For reference, PBD shown by a dotted line in FIG. 18 is a push button device. The push member (P) of the push button device (PBD) is implemented so that the moving cart 521 is pushed in the right direction by the elastic force of the spring (S) or the right movement is prohibited in a state retracted to the left. It is implemented so that pushing can be released. Therefore, when the operator wants to withdraw the tray cart 521 in the right direction, the push member P is unlocked by slightly pushing the tray cart 521 in the left direction. Accordingly, the push member P pushes the moving cart 521 in the right direction to some extent by the elastic force of the spring S, so that the tray cart 521 can be easily withdrawn by the operator. And when the operator pushes the drawn tray cart 521 in the left direction, the push member P is locked while retreating in the left direction by the tray cart 521.

Since the second loading device 570 has the same configuration as the first loading device 520, a description thereof will be omitted. Of course, depending on the implementation, the second loading device 570 may be implemented differently from the first loading device 520. That is, whether the second loading device 570 implements the moving belt of the discharge device 560 to be able to rotate forward and backward, so that the customer tray CT can be positioned in parallel on the left and right sides of the discharge space as in this embodiment. It may be implemented differently by modifying the first loading device 520 according to the design purpose, such as whether or not to implement.

<Description of the lifting device, lowering device, and lifting device>

19 is a schematic perspective view of the lifting device 530.

The lifting device 530 is divided into a first riser 531 and a second riser 532 and is provided.

The first lifter 531 raises a plurality of stacked customer trays CT in stages by a predetermined vertical distance (by the height distance of the customer tray), and the top customer tray CT among the stacked customer trays CT. Is raised to the intermediate point SP1m on the first sorting position SP1. The first lifter 531 includes a tray support member 531a and a support member lifter 531b.

The tray support member 531a supports a plurality of stacked loading trays CT in a vertical direction.

The support member elevator 531b raises the tray support member 531a step by step by a predetermined vertical distance.

The second lifter 532 raises the uppermost customer tray CT that has risen to the intermediate point SP1m by the first lifter 531 to an upper point SP1t on the first sorting position SP1. The second lifter 532 includes a support member 532a, a locking member 532b, and a lifting cylinder 532c.

The support member 532a is provided to be elevating.

The locking member 532b is coupled to the support member 532a to rotate while being tilted upward. The locking member 532b rotates while being flipped upward, but is not flipped downward. In addition, the locking member 532b is also raised and lowered in association with the lifting of the support member 532a.

The lifting cylinder 532c raises the support member 532a.

Since the lowering device 550 has the same configuration as the raising device 530, a detailed description thereof will be omitted. However, the lowering device 550 lowers the customer tray CT in the lowering position DWP.

In addition, since the lifting device 620 has the same configuration as the first riser 531, a detailed description thereof will be omitted. Of course, the lifting device 620 lifts the customer tray CT on the second sorting position SP2.

On the other hand, the operation of the lifting device 530 as described above is related to the operation of the horizontal transfer device 540 to be described later. Therefore, a description of the operation of the lifting device 530 will be described after the configuration of the horizontal transfer device 540.

For reference, reference numeral AU in FIG. 19 denotes an alignment unit. The alignment unit AU pushes and aligns the customer tray CT located at the upper point SP1t of the first sorting position SP1 in one direction (right direction in the drawing).

<Description of the horizontal transfer device>

20 is a schematic perspective view of the horizontal transfer device 540.

The horizontal transfer device 540 includes a moving frame 541, four tray matchers 542a to 542d, and a horizontal mover 543.

The moving frame 541 has a shape of a square frame through which the customer tray CT can pass. And the moving frame 541 is provided to be movable in the front-rear direction along the guide rail GR.

The four tray matchers 542a to 542d are installed on the moving frame 541 to form a pair of two facing each other in the front-rear direction. These four tray matching devices 542a to 542d each include a matching member AE and a cylinder CD.

The matching member AE is provided to be able to advance and retreat in the front and rear direction. And the matching member (AE) is provided with a matching pin (AP) protruding upward. Here, the mating pin (AP) has a circular cross-section, and the width of the matching pin (AP) is narrow as the upper portion of the matching pin (AP) goes upward. The matching pin AP may be inserted into the matching hole AH of the customer tray CT. Therefore, the area of the flat end surface of the matching pin AP is slightly smaller than the plan area of the matching hole AH.

The cylinder CD is provided as a driving source for advancing and retreating the matching member AE in the front-rear direction, and may be replaced with a motor or the like.

The horizontal mover 543 moves the moving frame 541 in the front-rear direction.

<Description of the operation of the lifting device and the horizontal transfer device>

The operation of the lifting device 530 and the horizontal transfer device 540 will be described with reference to the schematic diagrams of FIGS. 21 to 28.

FIG. 21 shows the 4 customer trays CT on which the supply device 510 is stacked and moved to the first sorting position SP1 on the left, and then the tray supporting member 531a of the first lifter 531 is stacked. It shows the state of supporting the customer tray (CT) of dogs.

In the state of Fig. 21, the first lifter 531 is operated so that the customer tray CT at the top of the stacked customer trays CT is slightly higher than the intermediate point SP1m on the first sorting position SP1. Ascend to rise. At this time, as shown in FIG. 22, the locking member 532b of the second lifter 532 is tilted upward by the forward rotation, allowing the customer tray CT to rise. As shown in FIG. 23, when the locking member 532b is positioned in the gripping space HS of the customer tray CT at the top, the locking member 532b rotates in reverse. In the state of FIG. 23, when the first lifter 531 slightly lowers the tray support member 531a to slightly lower the stacked customer tray CT, as shown in FIG. 24, the customer tray CT at the top is classified as the first. While being located at the midpoint SP1m of the position SP1, the locking member 532b of the second lifter 532 is in a state to support the customer tray CT at the top.

In the state of Fig. 24, the lifting cylinder 532c of the second lifter 532 is operated to lift the support member 532a as in Fig. 25. At this time, since the matching members (AE) forming a pair with the horizontal transfer device 540 are retracted in a direction away from each other, the customer tray CT supported by the locking member 532b is the moving frame 541 It passes through the inside of and rises slightly more than the upper point SP1t of the first classification position ST1. In the state of Fig. 25, as shown in Fig. 26, the matching members AE forming a pair of the horizontal transfer device 540 advance in a direction closer to each other. Then, the lifting cylinder 532c of the second lifter 532 is operated to lower the support member 532a, thereby placing the upper customer tray CT on the matching member AE as shown in FIG. 27. Accordingly, the customer tray CT is located at the upper point SP1t of the first sorting position SP1.

Further, in the state of Fig. 27, the matching pin AP of the matching member AE is inserted into the matching hole AH of the customer tray CT. And the alignment unit (AU) is operated to push the customer tray (CT) to the right to accurately align the position of the customer tray (CT). In general, the customer tray (CT) is owned by a producer that produces electronic components, so its specifications may be slightly different depending on the type. Therefore, when the type of the customer tray CT is different, the tolerance between the area of the flat end surface of the matching pin AP and the flat area of the matching hole AH may vary. In this case, the position and angle of the customer tray CT may be distorted, and accordingly, a defect may occur in the loading operation of the electronic component ED by the picker device 210. Therefore, by aligning the customer tray CT in one direction while the matching pin AP is inserted into the matching hole AH, it has been implemented to correct errors for all types of customer tray CT.

Therefore, in the state of FIG. 27, the electronic component ED brought by the picker device 210 is loaded in the customer tray CT.

In addition, when all the electronic components ED are loaded on the customer tray CT mounted on the matching member AE, the horizontal mover 543 operates to move the moving frame 541 to the rear as shown in FIG. 28. Accordingly, the customer tray CT is located in the descending position DWP.

In the state as shown in Fig. 28, the lowering device 550 and the horizontal conveying device 540 operate in the opposite direction to the operation of the lifting device 530 and the horizontal conveying device 540 mentioned above, thereby lowering the customer tray (CT) by one step. Let it. As described above, when the customer trays CT loaded with electronic components (ED) are sequentially stacked one by one at the lowering position, and all four customer trays (CT) supplied are stacked, the discharge device 560 operates and the stacked customers The trays CT are moved to the discharge position (DCP).

And the stacked customer trays CT located at the discharge location (DCP) are discharged in a state loaded on the second loading device 570 by an operator.

29 is a schematic perspective view of the water supply device 610.

The water supply device 610 includes a reciprocating cart 611 and a cart mover 612.

The reciprocating cart 611 may be loaded with one customer tray (CT), and is provided to be movable in the left and right directions.

The cart mover 612 moves the reciprocating cart 611 in the left and right directions.

In the above water supply device 610, the reciprocating cart 611 is moved from the receiving position (SDP) to the second sorting position (SP2) on the left by the forward and reverse operation of the cart moving device 612, or from the second sorting position (SP2). It moves to the supply and demand position (SDP) on the right. Of course, the customer tray (CT) supported by the reciprocating cart 611 is also moved from the receiving position (SDP) to the second sorting position (SP2) on the right side with the reciprocating cart 611 or from the second sorting position (SP2) to the left. It is moved to the supply and demand location (SDP).

And as described above, the customer tray CT in the second sorting position SP2 is raised to the upper point SP2t of the second sorting position SP2 by the lifting device 620. Accordingly, when all electronic components (ED) determined to be defective are loaded into the customer tray (CT) located at the upper point (SP2t) of the second sorting position (SP2) by the picker device (210), the lifting device (620) is operated. And lower the customer tray (CT). Of course, the lowered customer tray CT is moved to the receiving position by the supply and demand device 610, and is discharged to the outside of the electronic component sorting equipment EDSE by the operator.
