Description

[Technical Field]

[0001] The present disclosure relates to an observation device, a positioning jig, and a suction position data generation system used to observe electronic components (hereinafter simply referred to as "components") mounted on a board, and in particular to an observation device, a carrier tape positioning jig, and a suction position data generation system used to image components in order to obtain position information necessary for setting the suction position of a suction nozzle that suctions and holds the components in a mounting board manufacturing line. [Background technology]

[0002] A component mounting system for manufacturing a mounted board on which components are mounted includes a mounted board production line in which a plurality of work devices, such as a component mounting device, are arranged in series along the conveyance direction of the board. The component mounting device performs a component mounting operation in which components accommodated in pockets of a carrier tape supplied by a tape feeder are picked up by suction with a suction nozzle of a mounting head and mounted onto the board.

[0003] The suction nozzle's pickup position is usually determined to be at or near the center of the pocket on the carrier tape where the component is housed. However, for special components, such as those with irregular shapes (e.g., L-shaped in plan view), uneven weight distribution, or insufficient exterior strength, a pickup position must be individually set. In this case, it is necessary to measure the distance (offset amount) from the normal pickup position (the center of the pocket on the carrier tape or its vicinity) to the pickup position specific to the special component, create pickup position data indicating the pickup position after the offset, and store the data in the host device. Conventionally, pickup position data has been created based on images of the component housed in the pocket on the carrier tape captured by a board recognition camera installed in a component mounting device on a printed circuit board manufacturing line (see, for example, Patent Document 1).

[0004] On the other hand, there is a component recognition data inspection system that uses an offline camera unit that is separate from the mounting board production line and connected to a host device to capture images of components, and creates teaching data (component recognition data) from the captured images to accurately recognize components to be mounted on the board (see, for example, Patent Document 2). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2018-110188 [Patent Document 2] Japanese Patent Application Laid-Open No. 2015-144167 Summary of the Invention [Problem to be solved by the invention]

[0006] Incidentally, in order to capture an image of a component using the conventional technology disclosed in Patent Document 1, it is necessary to temporarily halt the operation of the mounting board production line, which increases the equipment downtime required to create pickup position data and causes problems in the production of mounting boards.On the other hand, if it were possible to capture an image of the component together with its carrier tape outside the mounting board production line, as with the offline camera unit disclosed in Patent Document 2, it would be possible to create pickup position data without affecting the operation of the mounting board production line, but there was a problem in that conventional offline camera units could not observe (capture) the component together with its carrier tape.

[0007] Therefore, the present disclosure aims to provide an observation device, a carrier tape positioning jig, and an adsorption position data generation system that can observe carrier tapes containing components at a position outside the mounting board manufacturing line that constitutes a component mounting system. [Means for solving the problem]

[0008] The observation device disclosed herein is an observation device for observing a carrier tape containing components, and comprises a positioning and holding means for positioning and holding the carrier tape, and an imaging unit for imaging the carrier tape held by the positioning and holding means, wherein the positioning and holding means comprises a first support member and a second support member having support surfaces that support both sides of the carrier tape from below, a pressing member that presses each of both sides of the carrier tape supported by the first support member and the second support member from above, and a mark formed on the upper surface of at least one of the first support member and the second support member for aligning the carrier tape to a predetermined position.

[0009] The carrier tape positioning jig of the present disclosure is a positioning jig used in an observation device that observes a carrier tape with components housed in pockets, and includes a first support member and a second support member having support surfaces that support both sides of the carrier tape from below, a pressing member that presses each of both sides of the carrier tape supported by the first support member and the second support member from above, and a mark formed on the support surface of at least one of the first support member and the second support member for aligning the carrier tape to a predetermined position.

[0010] The suction position data generation system of the present disclosure includes a processing device that generates, based on the data output from the observation device, suction position data of the suction nozzle used by a work device that mounts the component on a board using the suction nozzle when the work device uses the suction nozzle to remove the component from the carrier tape. [Effects of the Invention]

[0011] According to the present disclosure, it is possible to observe components accommodated in a carrier tape at a position away from the mounting board manufacturing line that constitutes the component mounting system. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0013] Next, embodiments of the present disclosure will be described with reference to the drawings.

[0014] (Component mounting system) First, a component mounting system in which the observation device of the present disclosure is installed will be described. FIG. 1 is an overall configuration diagram of a component mounting system equipped with an observation device of one embodiment of the present disclosure. As shown in FIG. 1, component mounting system 1 mainly includes a mounted board production line made up of working devices, namely, a printing device M1, a board transfer device M2, an inspection / mounting device M3, component mounting devices M4 and M5, an inspection / mounting device M6, a board transfer device M7, and a reflow device M8, connected in the board transport direction (direction of arrow X) in which a board 4 to be worked on is transported. The working devices (printing device M1 to reflow device M8) are connected via a communication network 2 and controlled by a host device 3 having the functionality of a management computer.

[0015] Printing device M1 prints solder onto the electrodes of board 4. Board transfer device M2 receives board 4 from printing device M1 and passes it on to downstream inspection and mounting device M3. Inspection and mounting device M3 inspects the solder printed on board 4 and mounts component E (Figure 7) onto board 4. Component mounting devices M4 and M5 mount component E onto board 4 sent from inspection and mounting device M3. Inspection and mounting device M6 inspects the mounting state of component E mounted on board 4 and mounts component E onto board 4. Board transfer device M7 receives board 4 from inspection and mounting device M6 and passes it on to downstream reflow device M8. The reflow device heats and melts the solder on board 4 to solder-bond board 4 and component E.

[0016] Inspection and mounting device M3, component mounting devices M4 and M5, and inspection and mounting device M6 are equipped with mounting heads equipped with suction nozzles. These devices are equipped with tape feeders that feed carrier tape T (Fig. 3) containing components E in a predetermined direction. Components E contained on carrier tape T, which is fed in a predetermined direction by the tape feeder, are sucked and held by the suction nozzles and mounted on board 4 positioned at a predetermined work position.

[0017] The host device 3 creates pickup position data indicating pickup positions of the components E accommodated on the carrier tape T, which is referenced when component mounting devices M4, M5, etc. mount the components E on the board 4. An observation device (camera device) 5, which is positioned outside the mounted board production line, is connected to the host device 3 via a communication network 2. The mounted board production line, which is made up of work devices (printing device M1 to reflow device M8), the host device 3, and the observation device 5 make up a component mounting system 1.

[0018] (Observation device) Next, the observation device 5 according to the present disclosure will be described with reference to FIGS. 2 to 6. FIG. 2 is a perspective view of the observation device according to an embodiment of the present disclosure. FIG. 3 is a perspective view of a carrier tape positioning jig in the observation device according to an embodiment of the present disclosure. FIG. 4 is a perspective view of a jig body in the observation device according to an embodiment of the present disclosure. FIG. 5 is a plan view of the jig body in the observation device according to an embodiment of the present disclosure. FIG. 6 is a partially enlarged perspective view of the jig body in the observation device according to an embodiment of the present disclosure. The observation device 5 has a function of observing the components E packed in the carrier tape T using a camera 5b (described later) when setting the suction position of the suction nozzle relative to the components E, and transmitting the acquired data to the host device 3. In this specification, "observation" includes "imaging" the observation target, including the carrier tape T and the components E. Because the observation device 5 is disposed outside the mounting board production line, it can also be referred to as an offline camera unit.

[0019] The observation device 5 is configured to include a cover 5a, a camera 5b as an imaging unit, a base portion 5c, and a positioning jig 10 (hereinafter simply referred to as the "positioning jig") for the carrier tape T. The cover 5a is provided to surround the upper part of the observation device 5, and the camera 5b is disposed inside the cover 5a. The camera 5b is disposed with its imaging surface facing downward, and is equipped with an observation light (not shown) that irradiates illumination light toward the positioning jig 10. The base portion 5c is disposed in the front-opening portion below the cover 5a, i.e., below the camera 5b, and the positioning jig 10, which will be described in detail later, is disposed thereon.

[0020] (positioning jig) Next, the positioning jig 10 will be described with reference to FIGS. 3 to 6. The positioning jig 10 fixes the carrier tape T containing components E in a predetermined position so that it can be imaged by the camera 5b. As shown in FIGS. 3 to 5, the positioning jig 10 includes a jig body 20 as a positioning and holding means, and a support portion 30. As shown in FIGS. 4 and 5, the carrier tape T is a tape-like packaging material that contains, transports, and stores components E. The carrier tape T has a plurality of pockets P arranged in series along its longitudinal direction, each of which contains one component E, and a plurality of sprocket holes (holes) H on one or both sides of the plurality of connected pockets P that engage with sprockets provided on a tape feeder set in the component mounting devices M4 and M5 (FIG. 7). The carrier tape T fixed to the jig body 20 is cut to a predetermined size and has at least one pocket P.

[0021] 3 and 4, the jig body 20 includes a rectangular plate-like member 21, a first support member 22, a first pressing member 23, a second support member 24, and a second pressing member 25. A metal member 21a that is attracted by a magnetic member 43 (described later) is provided at the front end (the end on the arrow Y2 side) of the underside of the plate-like member 21, and two finger holes 21b are provided at the rear end (the end on the arrow Y1 side).

[0022] As shown in Figures 4 and 6, the first support member 22 is a flat plate-like member erected from the upper surface of the plate-like member 21, and has an opening 22d (Figure 6) formed below it to prevent interference with a slide rail 26, which will be described in detail later. The upper surface of the first support member 22 forms a support surface 22a on which one side T1 of the carrier tape T, on which sprocket holes H are formed, is placed, and a pin member 22b is provided thereon as a marker for determining the fixing position of the one side T1. The sprocket hole H has a size that allows the pin member 22b to be inserted. In addition, a screw hole (not shown) into which a fixing screw 22c is screwed is provided on the outer surface of the first support member 22 (the side facing outward from the plate-like member 21).

[0023] The first pressing member 23 presses and fixes one side T1 of the carrier tape T against the support surface 22a of the first support member 22. The first pressing member 23 includes a pressing piece 23a provided opposite the support surface 22a, a fixing portion 23b bent downward from the pressing piece 23a by approximately 90 degrees and extending along the side surface of the first support member 22, and an operation piece 23c bent by approximately 90 degrees and extending laterally from the fixing portion 23b. A vertically elongated hole (not shown) through which a fixing screw 22c is inserted is formed in the fixing portion 23b at a position corresponding to the screw hole of the first support member 22, and when the fixing screw 22c is tightened, the first pressing member 23 is pressed against the outer surface of the first support member 22 and fixed.

[0024] The second support member 24 is a flat plate-like member erected on the upper surface of the plate-like member 21, attached to a slide rail 26 extending in the width direction (the direction of the arrows X1-X2) on the plate-like member 21, and is provided so as to be slidable toward or away from the first support member 22. The upper surface of the second support member 24 serves as a support surface 24a on which the other side T2 of the carrier tape T is placed, and the outer surface (the surface opposite the surface facing the first support member 22) is provided with screw holes (not shown) into which fixing screws 24b are threaded. In the carrier tape T of this embodiment, sprocket holes H are also formed at a predetermined pitch on the other side T2.

[0025] The second support member 24 is further provided with a slide restriction portion 27 that fixes the second support member 24 to the plate-like member 21. The slide restriction portion 27 includes a flat portion 27a that extends horizontally from below the outer surface of the second support member 24, and a fixing screw 27b that is screwed into a screw hole (not shown) provided in the flat portion 27a. The second support member 24 can be fixed by sliding the second support member 24 along the slide rail 26 to a desired position and then tightening a threaded portion (not shown) provided on the fixing screw 27b until the tip of the screw portion abuts against the upper surface of the plate-like member 21.

[0026] The second pressing member 25 presses and fixes the other side T2 of the carrier tape T against the support surface 24a. The second pressing member 25 includes a pressing piece 25a provided opposite the support surface 24a of the second support member 24, a fixing portion 25b bent approximately 90° downward from the pressing piece 25a and extending along the side surface of the second support member 24, and an operating piece 25c bent approximately 90° and extending laterally from the fixing portion 25b.

[0027] The fixing portion 25b has a vertically long hole (not shown) through which the fixing screw 24b is inserted, formed at a position corresponding to the screw hole of the second support member 24. When the fixing screw 24b is tightened, the fixing portion 25b is pressed against the outer surface of the second support member 24 and fixed, thereby completing the fixation of the carrier tape T to the jig body 20. The jig body 20 configured in this manner is supported by the support portion 30 and disposed on the base portion 5c.

[0028] 3, the support unit 30 includes a stage 40 and an elevating mechanism 50. The jig body 20 is detachably attached to the stage 40, and includes a pair of guide members 41, a movement restricting member 42, and a magnetic member 43. The pair of guide members 41 guide the jig body 20 so that it is positioned at a predetermined position on the stage 40, and are provided on both sides of the upper surface of the stage 40 so that both sides of the plate-like member 21 of the jig body 20 abut against the guide members 41 when the jig body 20 is attached toward the depth side (the arrow Y2 side).

[0029] The movement restricting member 42 restricts the upward movement (direction perpendicular to the XY plane) of the front end side of the jig body 20, which is guided by the guide member 41 and attached to the stage 40. As shown in FIG. 3, the movement restricting member 42 is formed in a rectangular plate shape, and is fixed to the stage 40 by bolts 42b with a base portion 42a made of a cylindrical member interposed between the movement restricting member 42 and the stage 40. The movement restricting member 42 is disposed at a position slightly higher than the height of the upper surface of the metal member 21a provided on the jig body 20. As a result, when the jig body 20 attempts to move upward, the metal member 21a comes into contact with the movement restricting member 42, restricting the movement.

[0030] The magnetic members 43 are disposed on both sides of the movement restricting member 42, and are equipped with magnets that are attracted to the end face of the metal member 21a provided on the jig body 20 attached to the stage 40. By attracting the metal member 21a to the magnetic members 43, the jig body 20 is detachably fixed in the depth direction (direction of arrow Y1-Y2).

[0031] To attach the jig body 20 to the stage 40, the operator holds the plate-shaped member 21 by hooking his or her fingers into the finger holes 21b, and moves the plate-shaped member 21 forward toward the depth side (arrow Y2 side) while abutting both sides of the plate-shaped member 21 against the guide members 41. In the process of moving the plate-shaped member 21 forward, the metal member 21a is positioned below the movement restricting member 42 and is attracted to the magnetic member 43. On the other hand, to remove the jig body 20, the operator pulls the plate-shaped member 21 forward (arrow Y1 direction) while hooking his or her fingers into the finger holes 21b.

[0032] 3, the lifting mechanism 50 adjusts the stage 40 to an arbitrary height position, and is configured to include a lifting operation unit 51 and an operation unit 52 on a base plate 53 fixed to the base portion 5c. The lifting operation unit 51 is formed by fixing a first link member 51a and a second link member 51b to each other at approximately the center thereof so as to be rotatable, and is disposed on both sides between the stage 40 and the base plate 53.

[0033] The upper end of the first link member 51a is rotatably fixed to a rear bracket (not shown) provided on the depth side (arrow Y2 side) of the underside of the stage 40, and the lower end is rotatably fixed to an acting portion 52b (described in detail below) provided on the front side (arrow Y1 side) of the base plate 53. The upper end of the second link member 51b is rotatably fixed to a front bracket (not shown) provided on the front side of the underside of the stage 40. The front bracket is slidably fixed to a slide rail (not shown) extending in the depth direction (arrow Y1-Y2 direction). The lower end of the second link member 51b is rotatably fixed to a rear bracket 53a provided on the depth side (arrow Y2 side) of the base plate 53.

[0034] The operation unit 52 includes a handle 52a and an action unit 52b. The action unit 52b is slidably disposed on a slide rail (not shown) that extends in the depth direction on the front side of the base plate 53, and the lower end of a second link member 51b is rotatably fixed to both ends via small links (not shown). The handle 52a is disposed on the front side of the action unit 52b. One end of a trapezoidal screw (not shown) is fixed to the back surface of the handle 52a, and the trapezoidal screw rotates in conjunction with the rotation of the handle 52a. The other end of the trapezoidal screw is threaded into a screw hole (not shown) formed in the action unit 52b, and the action unit 52b slides along the slide rail as the handle 52a is rotated. The first link member 51a and the second link member 51b rotate in conjunction with the sliding of the action unit 52b, thereby moving the stage 40 up and down.

[0035] The carrier tape T can be fixed to the jig body 20 configured as described above as follows. First, as shown in Figures 4 and 5, the operator places one side T1 of the carrier tape T on the support surface 22a of the first support member 22 while inserting the pin member 22b into a sprocket hole H1 that is located in a specific positional relationship with a pocket P formed in the carrier tape T, for example, a position corresponding to the center of the pocket P. Then, the operator moves the first pressing member 23 with the operating piece 23c and tightens the fixing screw 22c so that the pressing piece 23a presses the carrier tape T. As a result, one side T1 of the carrier tape T is sandwiched and fixed between the first support member 22 and the first pressing member 23.

[0036] Next, the operator slides second support member 24 to a position on support surface 24a where the other side T2 of carrier tape T can be placed, and tightens set screw 27b of slide restriction portion 27 to secure it in place. Then, the operator holds operation piece 25c and moves second presser member 25, tightening set screw 24b, so that presser piece 25a presses against carrier tape T. This secures the other side T2 of carrier tape T in a sandwiched state between second support member 24 and second presser member 25, completing the fixation of carrier tape T to jig body 20. Finally, the operator operates lifting mechanism 50 via handle 52a to adjust carrier tape T to a height suitable for imaging by camera 5b.

[0037] (Pickup position data generation system) The host device 3 has a control unit as an internal processing function, and functions as a processing device that generates suction position data that sets the suction position of the suction nozzle used when removing the component E from the carrier tape T based on the data output from the observation device 5.

[0038] The observation device 5 includes an imaging processing unit, a recognition processing unit, and an output unit. The imaging processing unit controls the camera 5b, observation lighting, etc. to capture an image of the carrier tape T fixed to the jig body 20. The recognition processing unit performs recognition processing on the image data acquired by the camera 5b. The output unit outputs the data generated by the recognition processing unit to the host device 3 via the communication network 2. The host device 3 and the observation device 5 constitute a suction position data generation system 100 (FIG. 1) that generates suction position data indicating the suction position by the suction nozzle.

[0039] FIG. 7 is a diagram illustrating image data acquired by a camera included in an observation device according to an embodiment of the present disclosure. FIG. 7 illustrates image data acquired by camera 5b. The image data includes images of sprocket holes H formed in carrier tape T, pockets P containing components E, and pin members 22b. While FIG. 7 illustrates image data, for ease of explanation, the objects being imaged (carrier tape, sprocket holes, components, pin members) are labeled with their actual symbols (T, H, E, 22b). The recognition processing unit performs recognition processing on the image data to generate data (relative position data) indicating the relative positional relationship between the position of the pocket P on the carrier tape T and the pin members 22b that serve as markers. The pocket P illustrated in FIG. 7 illustrates another example of a pocket P with a different shape from those illustrated in FIGS. 3, 4, and 5.

[0040] The relative positional relationship between the position of the pocket P and the pin member 22b can be defined, for example, based on the center (center position) C1 of the pocket P and the center C2 of the pin member 22b. The center C1 of the pocket P is determined, for example, by recognizing the outer shape (inner wall position) of the pocket P with a recognition processing unit and calculating it through a predetermined algorithm processing. The position of the pin member 22b is similarly calculated by recognizing and processing image data with the recognition processing unit. Alternatively, the relative positional relationship between the position of the pocket P and the pin member 22b may be defined based on the inner wall position of the pocket P, more specifically, the position PW1 of at least one side or the position PW2 of a corner that forms the inner wall, and the center C2 of the pin member 22b.

[0041] Next, a method for generating pickup position data using the pickup position data generation system 100 will be described using FIG. 9 while referring to the flowchart in FIG. 8 . FIG. 8 is a flowchart of the pickup position data generation method according to an embodiment of the present disclosure. FIG. 9 is an explanatory diagram of a registration screen displayed on a display unit included in a host device according to an embodiment of the present disclosure. When generating pickup position data, an operator first fixes a carrier tape T (strictly speaking, a piece obtained by partially cutting the carrier tape T) containing a component E to be observed to a jig body 20 included in the observation device 5. That is, the operator inserts a pin member 22b into a sprocket hole H1 (FIGS. 5, 7, etc.) formed at a position corresponding to the center of the pocket P among multiple sprocket holes H formed on one side T1 of the carrier tape T, and, while maintaining the inserted state, fixes both side ends of the carrier tape T to the first support member 22 and the second support member 24, respectively. Then, the operator operates a handle 52a to adjust the position between the imaging surface of the camera 5b and the carrier tape T.

[0042] Once the setting of the carrier tape T on the jig body 20 is complete, the imaging processing unit activates the camera 5b to capture an image of the carrier tape T and acquire image data (ST1: image data acquisition step). Next, the recognition processing unit performs recognition processing on the image data to generate data (relative position data) indicating the relative positional relationship between the position of the pocket P on the carrier tape T and the pin member 22b serving as a marker (ST2: position data generation step). Next, the output unit outputs the relative position data to the host device 3 (ST3: output step).

[0043] Next, the control unit of the host device 3 sets the suction reference position A by the suction nozzle based on the acquired relative position data (ST4: suction reference position setting step). For example, the control unit of the host device 3 sets the center C1 of the pocket P indicated by the relative position data to the suction reference position A (FIG. 7).

[0044] Next, the control unit of the host device 3 displays a registration screen D (FIG. 9) on a display unit such as a monitor equipped in the host device 3 for specifying the offset pickup position of the component E (ST5: display step). The registration screen D displays an image display field D1 displaying an image I including the component E stored in the pocket P. The operator operates a pointing device (operation / input unit) equipped in the host device 3 to move a pointer D2 displayed on the registration screen D and specify a component pickup position B where the component E will be picked up by the suction nozzle. In response to this specification, the control unit of the host device 3 calculates offset amounts (Δx, Δy) that indicate how far the component pickup position B is from the pickup reference position A in the X and Y directions (ST6: offset amount calculation step). The amount of deviation in the X and Y directions can be grasped through the offset amount display unit D3 displayed on the registration screen D.

[0045] Next, when the operator clicks the "OK button" D4 included in the registration screen D using a pointing device, the control unit of the host device 3 generates pickup position data indicating the offset component pickup position B and stores this data (ST5). If the operator wishes to re-specify component pickup position B, the "Cancel button" D5 is clicked. The stored pickup position data is reflected in the mounted board production line of the component mounting system 1, and the component E is now picked up and held at component pickup position B by the pickup nozzles of the component mounting devices M4, M5, and other work devices. That is, based on the data (relative position data) output from the observation device 5, the host device (processing device) 3 generates pickup position data for the pickup nozzle used when the work device that mounts the component E on the board 4 using the pickup nozzle picks up the component E from the carrier tape T using the pickup nozzle.

[0046] As described above, the observation device 5 in this embodiment is arranged outside a mounting board production line provided with a plurality of working devices for manufacturing a mounting board in which components E are mounted on a substrate 4, and is an observation device 5 for observing a carrier tape T in which components E are accommodated in pockets P, and is provided with a positioning and holding means (jig body 20) for positioning and holding the carrier tape T, and an imaging unit (camera 5b) for imaging the carrier tape T held by this positioning and holding means, and the positioning and holding means has support surfaces 22 that support both sides of the carrier tape T from below. a first pressing member 23 and a second pressing member 25 that press down from above on both sides of the carrier tape T supported by the first supporting member 22 and the second supporting member 24, and a mark (a pin member 22b that can be inserted into at least one of a plurality of holes formed along the longitudinal direction of the carrier tape T) that is formed on the support surface 22a, 24a of at least one of the first supporting member 22 and the second supporting member 24 to align the carrier tape T to a predetermined position. The observation device 5 also includes an adjustment means (slide rail 26) that adjusts the distance between the first supporting member 22 and the second supporting member 24.
