Description

  The present invention relates to a component supply apparatus for supplying components to a component mounting machine or the like.

  In general, a component mounter moves a component holding head above a component supply unit, and causes a nozzle as a holder provided in the component holding head to move down and ascend to place a component at the lower end of the nozzle. The components are picked up by vacuum suction, and then the component holding head is moved above the substrate, whereupon the nozzle is lowered and raised again to mount the component at a predetermined coordinate position on the substrate.

  In such a component mounting machine, a type using a tape feeder is known as a component supply device for supplying components to the component supply unit. The tape feeder uses a component supply reel on which a tape holding a component is wound as a component supply source, pulls out the tape from the component supply reel, and pitches the tape in synchronization with the mounting timing of the component. Supply to the component supply unit.

  In general, a plurality of tape feeders are mounted in parallel on one component mounter in order to improve productivity. More specifically, since the component mounter mounts a wide variety of components, a plurality of tape feeders and corresponding component supply reels are arranged in parallel with a gap as small as possible. Therefore, in performing an appropriate component mounting operation, it is necessary to set an appropriate component supply reel for each tape feeder. That is, the component mounting control information corresponding to the component supply device is downloaded from the host system on the component mounter side, and it is necessary to set an appropriate component supply reel for each tape feeder according to the component mounting control information. There is. Specifically, since the component supply reel is provided with component information (information such as the type, quantity, and characteristics of the component) in the form of a barcode, the component information is read and recognized. It is necessary to check and collate whether or not the component information required from the mounting control information is met.

  Conventionally, this verification and collation work is often performed by an operator using a bar code reader or the like. However, this verification / verification work must be performed every time the parts supply reel is used up and replaced with a new parts supply reel in addition to the initial setting of the parts supply reel at the start of mounting. Inefficiency and human error such as misplacement of parts supply reels may occur.

  With regard to this verification and collation work, Patent Document 1 discloses a technique for improving the work efficiency. The technology of Patent Document 1 enables a plurality of component supply reels set in a parallel state to be flipped upward, and a barcode attached to the side surface of the flipped-up component supply cassette is a portable barcode reader. It is to read. That is, in the technique of Patent Document 1, since the tape feeder and the component supply reel are arranged in parallel with almost no gap as described above, the barcode attached to the side surface of the component supply reel is the target component supply reel. Since it cannot be read directly without extraction, the component supply reel is flipped upward. However, in the technique of Patent Document 1, a person performs the work of flipping up the component supply reel and the operation of identifying the tape feeder to which the flipped-up component supply reel corresponds. Human mistakes such as reel misuse cannot be excluded.

  On the other hand, in Patent Document 2, an information indicator such as a barcode is attached to the tape feeder main body side, and a reader such as a barcode reader is arranged so as to be movable along the parallel direction of the tape feeder. Techniques that can automate child reading are disclosed. However, in the technique of Patent Document 2, barcode information (component information) attached to a component supply reel set in the tape feeder is read in advance, and the component information is displayed on the tape feeder main body side. The work to record in the child is necessary. In the first place, the component information is not recorded in the information indicator, and the component information changes when the set component supply reel changes. That is, according to the technique of Patent Document 2, it is necessary to move the component information from the component supply reel to the information indicator, which requires a prior work time. Moreover, since this movement work is performed by a person, human error cannot be eliminated.

  The problem to be solved by the present invention is that, in a component supply apparatus in which a plurality of component supply sources are mounted in parallel, the component information attached to each component supply source can be recognized efficiently, and the recognition It is to be able to eliminate mistakes.

  According to one aspect of the present invention, a plurality of component supply sources each having component information attached thereto is a component supply device that is mounted in a parallel state, and a specific component supply from a plurality of component supply sources in a parallel state Displacement means for displacing the source from the parallel state, identification means for identifying the component supply source displaced by the displacement means, and recognition means for recognizing component information attached to the component supply source displaced by the displacement means A component supply device is provided.

  In the present invention, the displacement means may be movable along the parallel direction of a plurality of component supply sources.

  Moreover, the component supply apparatus of this invention can further have a rotation means to rotate the component supply source which the said displacement means displaced.

  In the present invention, the component supply source is typically a component supply reel on which a tape holding a component is wound. In this case, the component information is generally attached to the side surface of the component supply reel. The present invention is suitably applied to a component supply apparatus in which such component supply reels are mounted in parallel.

  According to the present invention, the specific component supply source is displaced from the parallel state from the plurality of component supply sources in the parallel state, and the component information attached to the displaced component supply source is directly recognized. Can be recognized efficiently. Further, the displacement means performs the displacement of the component supply source without human intervention, and the identifying means identifies the displaced component supply source, so that it is possible to eliminate human error such as a mistake in the component supply reel.

It is a schematic plan view which shows the state which the symbol recognition apparatus by one Example of this invention images the label adhering to the side surface of a component supply reel. Same as above.

  FIG. 1 is a front view conceptually showing one embodiment of a component supply apparatus of the present invention, and FIG. 2 is a plan view showing a main part of the component supply apparatus of FIG.

  The component supply apparatus shown in FIGS. 1 and 2 is a type using a tape feeder 200. The tape feeder 200 uses a component supply reel 300 on which a tape holding a component is wound as a component supply source, pulls out the tape T from the component supply reel 300, and pitches the tape in synchronization with the component mounting timing. Thus, the component is supplied to the component supply unit (pick-up position by the nozzle 400 of the component mounter) P.

  The tape feeder 200 is mounted on a main body of a component mounter (not shown) in a state where a plurality of tape feeders are arranged in parallel in the width direction (X direction). The component supply reel 300 is held by a reel holder 310 and arranged in a one-to-one relationship with the tape feeder 200. That is, a plurality of component supply reels 300 are also mounted in a state of being arranged in parallel in the width direction (X direction).

  The reel holder 310 has a slide groove 311 in the longitudinal direction. A pair of fixed shafts 312 is inserted into the slide groove 311, whereby the reel holder 310 slides in a direction perpendicular to the longitudinal direction of the slide groove 311, that is, the parallel direction (X direction) of the component supply reels 300 ( Displacement) is possible.

  A barcode 301 is attached to the side surface of the component supply reel 300 as component information. However, since the component supply reels 300 are arranged in parallel as described above, the bar code 301 is blocked by the other component supply reels 300 even when observed from the alignment direction (X direction) in the parallel state. It cannot be read.

  Therefore, the component supply apparatus of this embodiment includes a displacement unit 500 that displaces one component supply reel 300 from the plurality of component supply reels 300 in the parallel state. The displacement means 500 of this embodiment uses a cylinder mechanism 510. The cylinder mechanism 510 is mounted on the transfer belt 520 and can move in the X direction along a pair of guide shafts 530. The transfer belt 520 is connected to the motor 540. Therefore, when the motor 540 is driven, the transfer belt 520 rotates and moves in the X direction, whereby the cylinder mechanism 510 moves along the X direction (the parallel direction of the component supply reels 300).

  The motor 540 is a servo motor, for example, and is controlled by the control unit 550. By controlling the motor 540 by the controller 550, the cylinder mechanism 510 on the transfer belt 520 can be positioned at a predetermined position. Then, by extending the cylinder mechanism 510 at the predetermined position, one component supply reel 300 can be displaced from the plurality of component supply reels 300 in the parallel state in a direction orthogonal to the parallel direction. That is, as described above, the reel holder 310 that holds the component supply reel 300 can slide (displace) in a direction perpendicular to the parallel direction (X direction) of the component supply reel 300, so that the cylinder mechanism 510 is extended. By pushing out the reel holder 310, only the component supply reel 300 held by the reel holder 310 is displaced in a direction orthogonal to the parallel direction of the component supply reel 300.

  An imaging means 600 is arranged as a recognition means for reading and recognizing the barcode 301 attached to the side surface of the displaced component supply reel 300. Specifically, the imaging unit 600 is arranged so that only the barcode 301 (component information) attached to the component supply reel 300 displaced from the parallel state can be read and recognized.

  In addition to arranging one imaging unit 600 as shown in FIGS. 2 and 3, two imaging units (plural units) can also be arranged as shown in FIG. A hatched area in FIGS. 3 and 4 indicates a readable range of the imaging unit 600. As shown in FIG. 4, when two imaging means 600 are arranged, if two displacement means 500 are arranged, the barcodes 301 of the two component supply reels 300 can be simultaneously read and recognized. In short, the image pickup means 600 may be arranged so as to read and recognize the barcode 301 (component information) attached to a specific (arbitrary) component supply reel 300 displaced from the parallel state. In addition, as shown in the Example mentioned later, an imaging means can also be enabled to move along the parallel direction of a component supply reel with a displacement means.

  The component information recognized by the imaging unit 600 is sent to the control unit 550, and the control unit 550 performs a verification check operation between the component information and the component mounting control information downloaded from the host system 700. Specifically, the control unit 550 stores component allocation data for each tape feeder 200 based on the component mounting control information described above, and determines whether the component allocation data matches the recognized component information. Check and verify.

  Here, the control unit 550 can specify which tape feeder 200 corresponds to the recognized component information for the component supply reel 300. That is, as described above, the control unit 550 controls the motor 540 that moves the displacement unit 500 (cylinder mechanism 510), and the cylinder mechanism 510 displaces the component supply reel 300 corresponding to which tape feeder 200 based on the control information. It is possible to specify whether or not In this case, the control unit 550 serves as “specification means for specifying the component supply source displaced by the displacement means” in the present invention, but the specification can also be performed by other means. For example, if the imaging unit 600 is provided with a distance measurement function, the component supply reel 300 displaced by the displacement unit can be specified based on the distance information.

  As described above, according to the present invention, the specific component supply reel 300 is displaced from the parallel state from the plurality of component supply reels 300 in the parallel state, and the barcode 301 attached to the displaced component supply reel 300. Can be recognized directly, so that component information can be recognized efficiently. Further, the displacement of the component supply reel 300 is performed by the displacing means 500 without human intervention, and the controller 550 (identifying means) can identify the displaced component supply reel 300, so that a human error such as a mistake in the component supply reel is caused. Can be eliminated.

  On the other hand, the component supply reel 123 is rotatably installed on the reel mounting portion 122 by the second shaft 123a. A component supply tape T for supporting a large number of electronic components is wound around the component supply reel 123 in the form of a reel. On the side surface of the component supply reel 123, a symbol such as a barcode is provided as component information related to the electronic component information. The displayed label 123b is attached.

  Although the label 123b on which a symbol such as a barcode is displayed as component information related to the electronic component information is attached to the side surface of the component supply reel 123 according to the present embodiment, the present invention is not limited to this. That is, a symbol such as a barcode can be directly printed on the side surface of the component supply reel 123 without being attached to the side surface of the component supply reel 123 according to the present invention. Further, the form of the symbol existing on the side surface of the component supply reel 123 is not limited to the barcode, and other forms of symbols such as letters and numbers can be applied. That is, in the present invention, it is sufficient that a symbol (component information) exists on the side surface of the component supply reel 123, and there is no particular limitation on the existence method and the symbol format.

The movement drive unit 132b includes a first motor 132b_1, a drive pulley (132b_2), and a transfer belt 132b_3. When the first motor 132b_1 is operated, the transfer belt 132b_3 is moved by the rotation of the driving pulley 132b_2 connected to the shaft of the first motor 132b_1. Since a part of the surface of the transfer belt 132b_3 is attached to the moving member 132a, the moving member 132a also moves when the transfer belt 132b_3 moves. Here, the first motor 132b_1 includes a servo motor, a step motor, and the like, and is controlled by the control unit 136.

  The shaft of the first motor 132b_1 according to the present embodiment is directly connected to the drive pulley 132b_2, but the present invention is not limited to this. That is, the first motor 132b_1 according to the present invention only needs to transmit power by the driving pulley 132b_2, and there is no particular limitation on the connection method or method of the first motor 132b_1 and the driving pulley 132b_2. For example, a speed reduction mechanism or a speed increase mechanism can be interposed between the first motor 132b_1 and the drive pulley (132b_2).

  The moving driving unit 132b according to the present embodiment uses belt moving means including the driving pulley 132b_2 and the transfer belt 132b_3, but the present invention is not limited to this. That is, the movement drive unit according to the present invention only needs to be able to move the moving member 132a, and there is no particular limitation on the configuration thereof. For example, a moving drive unit may be configured by connecting a screw (screw shaft) to the shaft of the first motor 132b_1 and installing a transfer nut screwed into the moving member 132a.

  The movement guide portion 132c functions to guide the movement of the movement member 132a. For this purpose, the movement guide portion 132c includes a guide member 132c_1 that passes through the movement guide hole 132a_1 of the movement member 132a and a guide member support 132c_2 that supports the guide member 132c_1.

  The guide member 132c_1 according to the present embodiment has a rod shape with a circular cross section, and the movement guide hole 132a_1 also has a circular shape, but the present invention is not limited to this. For example, the shape of the guide member 132c_1 according to the present invention can be formed with a quadrangular cross section and a polygonal shape, and the movement guide hole 132a_1 can also be formed to have a corresponding shape.

  On the other hand, the imaging device 133 performs a function of imaging the side surface (the surface to which the label 123b is attached) of the component supply reel 123, and is installed on the upper surface of the moving member 132a. The imaging device 133 includes a camera 133a and a mirror 133b. The camera 133a uses the mirror 133b to reflect and shoot the side surface of the adjacent component supply reel 123, and sends the captured data (video) to the control unit 136. The control unit 136 analyzes the captured video and takes necessary measures.

  The camera 133a according to the present embodiment performs an imaging operation through the mirror 133b, but the present invention is not limited to this. That is, the imaging device according to the present invention may not include a mirror. In this case, the camera 133a needs to be appropriately arranged so that the side surface of the component supply reel 123 can be directly imaged.

  Here, the camera 133a is described as “camera” and is described so as to acquire a two-dimensional image. However, for example, a laser scanning bar code reader that performs raster scanning or a one-dimensional line camera may be used. In short, any device that reads component information represented by symbols may be used.

  On the other hand, the reel mounting unit rotating device 134 is installed on the upper surface of the moving member 132a. The reel mounting unit rotating device (134) includes a pneumatic cylinder 134a and a rod 134b, and the controller 136 appropriately applies compressed air to the pneumatic cylinder 134a through valve control to control the movement of the rod 134b. That is, if compressed air is applied to the pneumatic cylinder 134 a so that the rod 134 b extends, one end of the rod 134 b pushes the buffer member 122 d portion of the reel mounting portion 122. Then, the reel mounting portion 122 rotates around the first shaft 122a. When the reel mounting portion 122 rotates about the first shaft 122a, the component supply reel 123 descends downward. That is, the component supply reel 123 rotates around the first shaft 122a.

That is, the reel mounting unit rotating device 134 according to the present invention may include a hydraulic cylinder having a hydraulic type.

  On the other hand, the reel rotating device 135 includes a second motor 135a installed on the upper surface of the base plate 131 and a roll part 135b installed on the shaft of the second motor 135a. The second motor 135a includes a servo motor, a step motor, and the like, and is controlled by the control unit 136.

  When the component supply reel 123 descends downward, the roll unit 135b contacts the peripheral surface of the component supply reel 123 and transmits the rotational power of the second motor 135a. That is, the reel rotation device 135 rotates the roll portion 135b to move the component supply reel 123 to the second position when the component supply reel 123 descends downward and contacts the roll portion 135b by the operation of the reel mounting portion rotation device 134. By rotating about the shaft 123a, the imaging device 133 assists in imaging.

  Although the shaft of the second motor 135a according to the present embodiment is directly connected to the roll portion 135b, the present invention is not limited to this. That is, the second motor 135a according to the present invention only needs to transmit power through the roll part 135b, and there is no particular limitation on the connection method or method of the second motor 135a and the roll part 135b. For example, a speed reduction mechanism or a speed increase mechanism can be interposed between the second motor 135a and the roll part 135b.

  On the other hand, the control unit 136 functions to control the overall driving of the symbol recognition device 130. The controller 136 may be implemented in various circuit formats such as an electronic circuit and an integrated circuit chip, and may be implemented in the form of a program that performs a control function.

  The control unit 136 according to the present embodiment is attached to the symbol recognition device 130 and controls only the symbol recognition device 130, but the present invention is not limited to this. That is, the control unit 136 according to the present invention is configured to be included from the beginning in the controller 24 of the component mounter 1 in which the symbol recognition device 130 is installed, thereby operating on a part of the controller 24 of the component mounter 1. be able to.

  The user installs the component supply device 100 on the operation side of the component mounter 1 in order to drive the component mounter 1. That is, the user prepares a component supply stand 110 on which a plurality of new tape feeders 120 are set in advance, and then uses the moving operation handle 112 to attach the component supply stand 110 to the coupling portion of the component mounter 1. 1 and the component supply stand 110 is installed in the component mounter 1 as shown in FIG.

  The control unit 136 of the symbol recognition device 130 drives the movement driving unit 132b to position the moving member 132a near the component supply reel 123 of the frontmost tape feeder 120 with respect to the X direction. The state at this time is as shown in FIG. 9A.

  Subsequently, as shown in FIG. 9B, the controller 136 applies compressed air to the pneumatic cylinder 134a through valve control to extend the rod 134b. Then, one end of the rod 134b pushes the buffer member 122d portion of the reel mounting portion 122, the reel mounting portion 122 rotates clockwise about the first shaft 122a, and the component supply reel 123 descends downward. And one end reaches the roll part 135b. At this time, the first elastic member 122b is deformed and accumulates elastic energy.

  Subsequently, as illustrated in FIG. 9B, the control unit 136 operates the camera 133 a of the imaging device 133 while operating the reel rotating device 135 to rotate the roll unit 135 b and proceeds to image the side surface of the component supply reel 123. When the roll part 135b rotates, the component supply reel 123 rotates around the second shaft 123a. When the captured image by the imaging device 133 is analyzed in real time and the label 123b is included in the captured image, the control unit 136 stops the rotation of the roll unit 135b and a symbol such as a barcode on the label 123b as shown in FIG. 10A. Analyze. The symbol analysis result analyzed by the control unit 136 is sent to the controller 24 of the component mounting machine 1 and used for the electronic component mounting work. That is, since a symbol such as a bar code written on the label 123b is related to the type of electronic component stored in the component supply reel 123, if the symbol analysis result is used, it is preliminarily placed at each position on the substrate 16. The determined electronic component can be accurately mounted.

  Subsequently, as shown in FIG. 9D, the control unit 136 contracts the rod 134b of the hydraulic cylinder 134a through valve control. Then, the first elastic member 122b in which the elastic energy is accumulated in the previous process returns to the original state, and the reel mounting portion 122 rotates counterclockwise about the first shaft 122a. As a result, the component supply reel 123 rises upward, and one end is separated from the roll part 135b.

  Through the process as described above, the label 123b of the component supply reel 123 of the frontmost tape feeder 120 is photographed with reference to the X direction, and a symbol such as a barcode of the photographed label 123b can be analyzed.

  Subsequently, the control unit 136 drives the movement driving unit 132b to position the moving member 132a in the vicinity of the component supply reel 123 ′ of the second tape feeder 120 with reference to the X direction, and then repeats the above process to repeat FIG. 10B. As shown in FIG. 5, the symbols such as the barcode of the label 123b ′ of the second component supply reel 123 ′ are analyzed. The above process is successively performed for the barcode recognition of the label 123b "of the third component supply reel 123" and the label 123b "" of the fourth component supply reel 123 "". That is, by applying the above process to the component supply reels of all the tape feeders 120 and sending the symbol analysis result thus obtained to the controller 24 of the component mounter 1, Used for electronic component mounting work.

  As described above, according to the component supply apparatus 100 of the present embodiment, the labels 123b, 123b ′, 123b of the component supply reels 123, 123 ′, 123 ″, 123 ′ ″ of the plurality of tape feeders 120 are automatically provided. By recognizing and analyzing the symbols “, 123b ′” one after another, the user can recognize the symbols faster and more accurately than when the user manually recognizes the symbols. That is, when the user performs the operation manually, since a plurality of component supply reels are arranged, the labels on the side surfaces of the component supply reels must be searched and recognized one by one. . On the other hand, if the component supply apparatus 100 of the present embodiment is used, human error can be eliminated and the recognition speed can be increased. At the same time, according to the component supply apparatus 100 of the present embodiment, the component supply apparatus 100 is connected to the component mounter 1, and therefore the symbol analysis result analyzed by the control unit 136 is immediately sent to the controller 24 of the component mounter 1. It can be used to control the component mounting machine 1 and is advantageous for data transmission and interlocking control.
