Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component supply method and apparatus for supplying components for various operations, and a component mounting apparatus for mounting components on a mounting object by using the same.
For example, it is used for supplying electronic components in a case where various electronic components are mounted on a circuit board to manufacture an electronic circuit board, and for manufacturing an electronic circuit board using the same.

[0002]

2. Description of the Related Art Recently, miniaturization of products has been progressing as represented by mobile phones. As a result, the size of electronic circuit boards has become smaller, and while miniaturization has been required for high-density mounting of electronic components, large-scale chips such as QFPs, CSPs, and module chips have been developed due to the high performance and high density of electronic components themselves. The opportunity to mount such a large electronic component on a circuit board is increasing.

[0003] Such large-sized electronic components are accommodated in trays in a planar arrangement so that a large number of electronic components can be stably supplied while handling them in bulk. Also,
In recent years, large-sized products have advanced multi-functionality, and it is necessary to mount many types of electronic components on one circuit board. It is desirable to be able to supply various kinds of electronic components as needed at the same time in the same component mounting apparatus.

To cope with this, conventionally, a large number of trays accommodating different types of electronic components are arranged and accommodated in a single tray accommodating portion, and the tray accommodating the necessary electronic components is pulled out and supplied at each time. I can do it.

FIG. 4 shows an example of such a conventional apparatus. In this apparatus, an empty tray can be disposed of outside the apparatus while supplying various kinds of tray parts as described above.

To explain this, as shown in FIG. 4, a tray a in which electronic components are stored is supported by a support plate b and stored in a tray storage section c which moves up and down in multiple stages. The tray storage section c is moved up and down by an elevating mechanism e to make each support plate b or its storage section appropriately correspond to the height of the component supply section d, and to store the component supply section d and the tray storage section c corresponding thereto. The support plate b is moved in and out of the tray a by the take-out mechanism p, and each time the support plate b is pulled out, the electronic components in the tray a supported by the support plate b are supplied to the component handling mechanism f and used for handling. The component handling mechanism f has a mounting head i that is moved by moving axes g and h in orthogonal XY2 directions.
The supplied electronic component is picked up by a suction nozzle j (in FIG. 4, waiting at a tool changing station k in FIG. 4), carried to a component mounting section m, and a circuit board n positioned there is picked up. Attach in place. By repeating the above, predetermined electronic components are mounted on the circuit board n to manufacture an electronic circuit board.

When the tray a becomes empty due to the supply of electronic components in the component supply section d, the component handling mechanism f temporarily moves the suction nozzle j of the mounting head i to the tray suction pad o as shown in FIG. The replacement is performed at the tool exchange station k. Next, the empty tray a above the support plate b at the component supply position is sucked and lifted by the replaced tray suction pad o. In this state, the support plate b is stored in the corresponding storage section of the tray storage section c by the loading / unloading mechanism p. At this time, the upper and lower passages q in the component supply unit d are opened by the retraction of the loading / unloading mechanism p due to the storage of the support plate b, so that the empty tray a lifted by the tray suction pad o is removed from the upper and lower passages q. The tray a is discharged through the opened upper and lower passages q onto the disposal conveyor r below the tray, and the discharged tray a is disposed of from the disposal window s to the outside of the apparatus by driving the disposal conveyor r.

[0008]

However, in the above-mentioned conventional apparatus, since the waste conveyor r extending from the lower part of the component supply section d to the outside of the apparatus overlaps the component supply section d in two upper and lower stages, the mechanism density is reduced. However, it becomes complicated, expensive and large. Also, the operation of discharging the empty tray a from the component supply unit d for disposal is performed during the component mounting sequence operation in which various electronic components supplied by the component handling mechanism f are repeatedly mounted on the circuit board n. Since the component mounting operation is interrupted each time an empty tray h is discharged, the work efficiency of component mounting is reduced. In addition, each time the mounting head i discharges the empty tray a, and each time when the mounting head i finishes discharging and returns to the component mounting operation, the suction nozzle j moves to the tray suction pad o, and the tray suction pad o moves to the suction nozzle j. In the case of replacement, the loss time becomes longer, which also reduces the work efficiency.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a component supply method and a device which can reduce the size of the device simply and at low cost and improve the efficiency of repetitive work by sequentially using components to be supplied as needed. An object of the present invention is to provide a component mounting apparatus used.

[0010]

In order to achieve the above-mentioned object, a component supply method according to the present invention comprises: Each support plate or its storage section is properly inserted and removed from the component supply position corresponding to the height of the component supply position, and each time the support plate is pulled out, the components in the tray supported by the support plate are handled. It is supplied to the mechanism and used for handling parts, and when the tray is emptied at the parts supply position, it is once discharged from the support plate by the parts handling mechanism to discard it outside, and the support after the tray is discharged Repeatedly storing the plate in the tray storage unit and supplying the parts stored in each tray in the tray storage unit as needed At the same time, the disposal plate is also stacked and stored, and when the tray is emptied at the component supply position, the empty tray is once lifted by the component handling mechanism, and the disposal plate is raised to the height of the component supply position. After discharging the empty tray raised by the component transfer mechanism onto the pulled out disposal plate, the disposal plate receiving this tray is stored again in the tray storage section, One feature is that the discharge tray is disposed at a tray disposal position set separately from the component supply position and the discharge tray is disposed outside from the disposal plate.

[0011] Thus, a large number of trays are supported by the support plate and housed in the tray housing so that they can be individually put in and taken out of the tray storage section, and the tray containing necessary parts is moved to the parts supply position together with the support plate each time. The tray that has been emptied at the component supply position is ejected and discarded while repeatedly pulling out and supplying and providing various types of component handling by the component handling mechanism. Once the mechanism is lifted up, the support plate in the pulled-out state is stored in the tray storage section, and the discard plate stored so that it can be taken in and out together with the support plate in the tray storage section is supplied without disturbing the support plate. Pull out to position. The component handling mechanism ejects the empty tray once lifted onto the drawn-out discard plate so that the new tray containing the components can be stored in place of the empty tray. Is stored in the tray storage section again,
The tray required next to the component supply position is not obstructed from being pulled out together with the support tray. The disposal tray stored in the tray storage together with the empty tray is disposed outside from the tray storage when positioned at the tray disposal position, so that the next empty tray can be stored and disposed.

Therefore, the components stored in the large number of trays stored in the tray storage portion are supplied to the component supply position according to the needs at each time, and are emptied at the component supply position while being subjected to various kinds of handling. To discharge the waste tray from the normal handling route for parts supply and dispose of it outside
The operation can be performed through the component supply position and the tray storage section, and there is no need for a dedicated device or space for that purpose, so that the apparatus can be simplified and the cost can be reduced.

As a component supply apparatus for realizing this, a tray storage unit for storing a tray storing components on a support plate so that the tray can be individually taken in and out, a lifting mechanism for raising and lowering the tray storage unit, and a lifting mechanism A support plate in the tray storage portion to be provided or a component supply portion provided so as to correspond to the storage portion at a predetermined height, and support between the component supply portion and the storage portion of the corresponding tray storage portion. A loading / unloading mechanism for feeding and unloading the plate and taking out the components contained in the tray on the support plate that has been pulled out to a component handling mechanism for handling the components in various ways, and for handling the components; The discard plate stored so that it can be separately taken in and out together with the support plate in the section, and the component supply section are set separately,
A tray discarding section in which the discarding plate stored in the tray storing section to be moved up and down, and a discarding mechanism for discarding the tray supported by the discarding plate located in the tray discarding section from the discarding plate to the outside of the apparatus. It is enough if you prepare.

When the tray is emptied in the component supply section, the empty tray is once lifted by the component handling mechanism, and the discard plate is moved up and down by the lifting mechanism to move the discard plate to the component supply position. The parts handling mechanism ejects the empty tray that has been lifted once onto the discarded plate that has been pulled out, and then disposes the discard plate that has received this discharge tray by using the ejector mechanism. The tray is stored in the tray storage unit again, and the tray is moved up and down by the elevating mechanism so as to correspond to the tray discarding unit, and the discharge tray is controlled by the discarding mechanism to be discarded from the discard plate to the outside of the apparatus. Control means is required.

When the parts supplied by the parts supply unit are transferred and supplied to a working machine which repeatedly uses various parts by a parts handling mechanism and supplied to the working machine, the parts are supplied to the working machine. Since the operation of discharging the empty tray during the supply operation and discarding the tray outside can be performed outside the cycle of the repetitive operation in which the supplied component is used, it is possible to avoid reducing the efficiency of the repetitive operation in which the component is used.

If the component handling mechanism is provided with a component handling tool for holding and handling components supplied by the component supply unit and a tray handling tool for holding and handling empty trays in the component supply unit. While the parts handling mechanism is handling various parts supplied by the parts handling tool, when empty trays are ejected for disposal, it can be done instantly simply by selecting and using the tray handling tool. The work efficiency is improved by eliminating the time loss due to the two tool exchanges required conventionally, and the component supply interval between the operations of discharging the empty tray is not affected by the cycle interval of the repetitive operation in the working machine using the components. , It is advantageous to set a shorter time interval.

In the present embodiment, the electronic component 1 supplied by the component supply unit 5 is transferred by the component handling mechanism 6 to the component mounting mechanism 21 as a working machine that repeatedly uses various electronic components 1 to work. And the component mounting mechanism 21
To work with. Accordingly, the operation of discharging the empty tray 2 during the component supply operation and discarding the tray outside can be performed outside the cycle of the repetitive operation in which the supplied electronic component 1 is used. It is possible to avoid lowering.

The component mounting mechanism 21 includes a component handling mechanism 6
The electronic component 1 transferred to the transfer table 22 in the component transfer section 20 is mounted on the circuit board 24 to manufacture an electronic circuit board, and together with the component supply device, forms one component mounting device. And a mounting head 25 equipped with a number of component handling tools 23 for mounting the transferred electronic component 1. The component handling tool 23 is a suction nozzle in the illustrated embodiment, but may be another holding type such as a chuck.

The component handling tool 23 according to the type of the electronic component 1 picked up by the rotation and then the component transfer unit 20
Various kinds of auxiliary work necessary for picking up and carrying the next electronic component 1, such as selection and proper inspection, are performed.

The tray storage section 4 has a box shape and has an access port 4b which is open on one side. Through the access port 4b, the support plate 3 alone or the tray 2 while being supported, and the disposal plate 7 alone. Alternatively, loading and unloading is performed with the empty tray 2 received.
However, pulling out of the discard plate 7 having received the empty tray 2 is not actually performed.

The tray storage section 4 is provided with a main body 31 of the component supply device.
The component supply unit 5 is provided so as to be supported by the lifting table 32 of the lifting mechanism 11 so as to be able to move up and down. The tray discarding section 8 is set at the lowest position in the main body 31, and the discarding mechanism 15 is installed there.

The elevating mechanism 11 guides the elevating table 32 by two guides 33, and rotates the screw shaft 34 forward and backward by a motor 35, thereby moving the elevating table 32 together with the tray storage unit 4. When the tray storage unit 4 is supported so as to be detachable from the elevating table 32, the type of the electronic component 1 can be changed and resupplied by exchanging the single unit. In order to supply the electronic components 1 to the tray storage portion 4 taken out after use, the empty tray 2 has already been discarded and is not left, so the new tray 2 containing the electronic components 1 is replaced with the vacant support plate 3. And can be stored automatically or manually.

However, even if the tray storage unit 4 cannot be removed from the elevator 32, if necessary, another insertion port is provided in a direction different from the entrance 4b, so that the tray storage unit 4 can be used even during component supply or when component supply is stopped. 2 can be supplied automatically or manually.

The component supply section 5 is of a table type and corresponds to a not-shown plate slot of the main body 31, and supports plate 3 and discard plate 7 through the plate slot.
A guide rail 41 for guiding the loading and unloading, and a loading and unloading mechanism 12 are provided. The loading / unloading mechanism 12 includes a loading / unloading body 43 having an engaging portion (not shown) that engages with a gripping engaging portion 42 provided on the support plate 3 or the disposal plate 7 as shown in FIG. , And a motor 45 that drives the drive belt 44 forward and reverse to move the plates 3 and 7 into and out of the loading and unloading body 43.

The component handling mechanism 6 has a transfer head 47 that is reciprocated by the Y axis 48 between the component supply unit 5 and the component transfer unit 20. The transfer head 47 includes the component handling tool 13 and the tray. Both handling tools 14 are provided. Thus, when the component handling mechanism 6 handles the electronic component 1 supplied by the component handling tool 13 in various ways, the tray handling tool 14 is selectively used when the empty tray 2 is discharged for disposal. Can be done instantaneously, eliminating the time loss due to the two required tool changes, improving the work efficiency, and setting the component supply interval between the operations of discharging the empty tray 2 to the component using the electronic component 1. This is advantageous in setting a shorter time interval that does not affect the cycle interval of the repetitive work in the mounting mechanism 21 or the like.

The component handling tool 13 shown in FIG. 1 is a suction nozzle 13a, and the tray handling tool 14 is a tray suction pad 14a. However, the present invention is not limited to this. Can be substituted. The suction nozzle 13a is mounted on the transfer head 4.
The suction nozzle 13a can be switched to a turret type by the rotation of the rotating body 47a depending on the type of the electronic component 1 to be handled by rotating the rotating body 47a.

As shown in FIG. 2, the discarding mechanism 15 is supported by a guide 52 and a screw shaft 53 so that a pusher 51 having a plurality of rake-shaped pushing pieces 51a can be moved forward and backward by a screw shaft 53. Is driven forward and reverse by a motor 54, so that the pusher 51 can be pushed backward and pulled out forward. Correspondingly, a plurality of escape windows 7a on the disposal plate 7 from which the plurality of pushing pieces 51a of the pusher 51 are pulled out from below as shown in FIG. 2 to prevent the tray 2 from falling off. The width and the pitch are provided so as to cover the advance / retreat range of the pushing piece 51a.

As a result, the discarding plate 7 receives the empty tray 2 as indicated by the phantom line in FIG. 2 and is stored in the tray storage section 4, and is located at the position of the tray disposal section 8 as shown in FIG. When moved, the pushing piece 51a protrudes upward through the opening 4c shown in FIG. 1 at the bottom of the tray storage section 4 and through the escape window 7a of the discard plate 7 as shown in FIG. In this state, when the motor 54 rotates forward and the pusher 51 advances, the empty tray 2 on which the discard plate 7 is received is discarded from the discard window 55 of the main body 31 to the outside of the apparatus. After being discarded, the motor 54 rotates reversely and returns the pusher 51 to its original position.

However, since the specific configuration of each mechanism can be variously changed in design, it is not limited to the present embodiment and the specific structure shown.

Empty tray 2 under the control of controller 16
A specific control example of the supply state of the electronic component 1 including the discharge and disposal of the electronic component 1 will be described with reference to the flowchart of the main operation control shown in FIG. As shown in FIG. 3, the normal operation of component transfer in which the electronic components 1 are sequentially supplied and transferred to the component mounting mechanism 21 is performed until the completion of the transfer unless an empty tray 2 is generated in the component supply unit 5. You can continue.

When a partially empty tray 2 occurs, a tray discharging operation is temporarily performed. This tray ejection operation
First, the empty tray 2 is sucked and held, and the support plate 3
Is stored in the tray storage section 4, the discard plate 7 is pulled out from the tray storage section 4, and the empty tray 2 held above is discharged onto the drawn discard plate 7.

Subsequently, the discard plate 7 having received the empty tray 2 is stored in the tray storage section 4 and the process is terminated.

Thereafter, the operation proceeds to the operation of discarding the empty tray 2. This discarding operation is performed after the discard plate 7 receiving the empty tray 2 stored in the tray storage unit 4 is moved to the tray discard unit 8 and then discarded outside the apparatus by the tray discard unit 8. .

However, the discarding operation does not need to be performed immediately after the discharging operation, but can be performed at an appropriate timing while continuing the component transfer operation after the discharging operation.
This timing is controlled by the component mounting mechanism 21 for one circuit board 2
When the component mounting in step 4 is completed and the time is set in accordance with the time lag caused by various causes, such as a time lag required for preparing for mounting the component on the next circuit board 24, sufficient time is required Can be performed without any effect.
In some cases, replenishment of a new tray 2 to the tray storage unit 4 can be performed. According to such a disposal specification, when a plurality of disposal plates 7 are stored in the tray storage section 4,
It is possible to cope with a case where another tray 2 becomes empty during standby until the empty tray 2 is discarded.

[0048]

According to the present invention, components stored in a large number of trays stored in a tray storage portion are supplied to a component supply position according to the needs at each time, and the components are supplied to various handlings. The tray emptied at the supply position can be discharged from the normal handling path for component supply and discarded outside, through the component supply position and the tray storage section,
There is no need for special equipment or space for it,
The apparatus can be simplified and the cost can be reduced.

In addition, since the operation of discharging the empty tray during the component supply operation and discarding the tray outside can be performed outside the cycle of the repetitive operation in which the supplied component is used, the efficiency of the repetitive operation in which the component is used is reduced. Can be avoided.

Further, when the component handling mechanism handles various kinds of components supplied by the component handling tool, when the empty tray is discharged for disposal, it is sufficient to select and use the tray handling tool. This eliminates the time loss due to the two tool changes that were required in the past, improves work efficiency, and sets the component supply interval between operations for discharging empty trays to a cycle of repetitive work using a work machine that uses parts. It is advantageous to set a shorter time interval that does not affect the interval.
