  In FIG. 9D, the bus bar BB3 stands vertically with respect to the surface H2 of the solar cell body TD, and is in a state of being bent obliquely at the tip.

  In addition to these, the bus bar BB can have other various shapes such as a shape that draws a loose arc or a shape that is bent in a dogleg shape.

  In the figure, the bus bar BB is entirely exposed on the surface H2 of the solar cell main body TD, but actually, a part of the bus bar BB forms a surface H2 of the solar cell main body TD. It gets inside the film.

  Further, a film material made of a synthetic resin or the like is attached to the bus bar BB for each bus bar BB or across the bus bars BB in the vicinity of the root of the portion exposed on the surface H2 for protection or the like. May be.

  For example, the bus bar BB in a standing state as shown in FIGS. 9 (B) to 9 (D) is covered with a terminal box, and the bus bar BB is bent into a curved shape, and its tip is inserted into the terminal hole of the terminal. And a terminal and the front-end | tip part of the bus bar BB inserted in the terminal are connected and fixed by soldering.

  The claw member is rotatably supported by a rotation shaft, and is urged toward the original position in the rotation direction by a spring member or the like so that the initial posture is maintained in a free state.

  The bus bar BB is further bent by the rotation of the claw member, and finally pressed by being sandwiched between the surface of the claw member (work raising surface) and the end block, as shown in FIGS. 9B to 9D. Formed.

  The suction pad releases suction and moves upward and retracts immediately after the claw member is inserted into the gap at the tip of the bus bar BB.

The processing apparatus 1 according to the first embodiment to be described next realizes such a series of operations by a movement drive by a single hydraulic cylinder and a cam mechanism.
[First Embodiment]
The external shape of the processing apparatus 1 is shown by FIGS.

  1 to 4, the processing apparatus 1 includes a main body 11, an end block 12, a pneumatic cylinder 13, a moving block 14, a claw device 15, and a suction device 16.

  The main body 11 is a structure that supports the entire processing apparatus 1, and is configured by integrally connecting a frame material, a block material, a plate material, and the like made of metal or synthetic resin with bolts or the like.

  In the example shown in the figure, the main body 11 includes substrates 21 and 22 arranged in the vertical direction, connecting plates 23 arranged in the horizontal direction in contact with the upper end surfaces of the substrates 21 and 22, and the like. The board | substrate 21 and the board | substrate 22 are arrange | positioned at an angle of a right angle mutually.

  The substrates 21 and 22 and the connecting plate 23 are all plate-like materials made of a metal material such as steel and are integrally connected to each other by bolts.

  The connecting plate 23 is connected and fixed to the moving device 17. By the moving device 17, the processing device 1 is moved and positioned at an arbitrary position in the three-dimensional space in which the solar cell main body TD is arranged. As such a moving device 17, devices having various structures, methods, and shapes can be used. For example, an articulated robot or an XYZ positioning device combining a plurality of XY tables can be used as the moving device 17.

  The end block 12 is disposed so that the edge portion 32 is in contact with the surface of the bus bar BB at the bent position of the bus bar BB.

  That is, the end block 12 is attached to a block 24 attached to the lower end portion of the substrate 21. The front side surface 31 of the end block 12 is a vertical plane, and the side portion at the boundary between the front side surface 31 and the horizontal bottom surface is an edge portion 32.

  Although not shown in the drawing, guide members for guiding the bus bar BB may be provided on both sides of the edge portion 32. By providing the guide member, the bus bar BB can be bent more accurately.

  The pneumatic cylinder 13 is a double-acting operating cylinder in which the piston and the piston rod 41 extend and contract by alternately supplying compressed air to the two supply / discharge ports PT1 and PT2. In the pneumatic cylinder 13, guide rods 42 and 42 are provided on both sides of the piston rod 41, and a tip block 43 is attached to the tip portions of the piston rod 41 and the guide rods 42 and 42.

  The pneumatic cylinder 13 is fixed to the surface of the substrate 22 with bolts, and the tip block 43 is driven to move in the left-right direction in FIG.

  The moving block 14 is a plate made of a material such as steel, and is attached to the tip block 43 with a bolt or the like. Therefore, when the tip block 43 is moved by the pneumatic cylinder 13, the moving block 14 moves integrally with the tip block 43.

  The moving block 14 is provided with a cam surface 51 at its upper end surface, and the suction pad 71 moves up and down in accordance with the change of the cam surface 51 as will be described later. The cam surface 51 is constituted by three consecutive planes, the lowest horizontal plane 51a, the inclined plane 51b, and the highest horizontal plane 51c.

  The claw device 15 includes a claw member 61, a rotation shaft 62, a bearing unit 63, a rotation original position adjusting device 64, and the like.

  As shown in FIG. 1, the claw member 61 has a shape in which a rectangular member is connected to a geometric base of a parallel trapezoid in a front view. That is, the claw member 61 is an acute angle with respect to the bottom surface 61a on the side close to the end block 12 in the bottom surface 61a that is in contact with the bottom surface 61a slidably contacting the surface H2 of the solar cell body TD and the back surface of the bus bar BB. It has a work raising surface 61b that intersects (45 degrees in this example). A ridge line where the bottom surface 61a and the work raising surface 61b intersect is a tip portion 61c.

  The rotating shaft 62 is rotatably supported by a bearing unit 63 attached to the moving block 14. The rotating shaft 62 passes through the bearing unit 63 and the moving block 14 and protrudes at both side ends thereof. The claw member 61 is fixed to one end portion of the rotation shaft 62, and the rotation original position adjusting device 64 is provided to the other end portion.

  That is, the claw member 61 is rotatably supported by the rotation shaft 62 and is arranged such that the work raising surface 61b exists at a position away from the rotation shaft 62 by a predetermined distance.

  The rotation original position adjusting device 64 adjusts and regulates the rotation angle of the rotation shaft 62. That is, the tip of the adjustment screw 66 screwed into the adjustment plate 65 attached to the moving block 14 comes into contact with the rotation original position adjustment device 64 fixed so as to rotate integrally with the rotation shaft 62 ( As a result, the original position of the claw member 61 is defined. The original position of the claw member 61 can be adjusted by the adjusting screw 66.

  A coil spring 67 is mounted on the outer peripheral surface of the rotation shaft 62 between the bearing unit 63 and the rotation original position adjusting device 64. When the coil spring 67 is compressed, both ends thereof are locked to the bearing unit 63 and the rotation home position adjusting device 64, so that the rotation home position adjusting device 64 is attached to the tip of the adjustment screw 66 in a free state. It is biased to abut.

  Accordingly, the claw member 61 can rotate rightward with respect to the original position shown in FIG. 1, but cannot rotate leftward, and is biased leftward to be in a free state. At the original position.

  In this manner, the claw member 61 can move with respect to the main body 11 along the surface of the solar cell main body TD and along the bending direction of the bus bar BB, and can rotate within a plane including the bending direction. In this manner, the rotating shaft 62 is supported.

  Therefore, when the moving block 14 moves, the bottom surface 61a of the claw member 61 moves along the surface of the solar cell body TD. When the claw member 61 moves, the work raising surface 61b enters the back surface of the bus bar BB, and the bus bar BB is raised with the movement.

  The suction device 16 includes a suction pad 71, a support plate 72, a copying device 73, a support guide 74, and the like.

  The suction pad 71 includes a pad made of a synthetic rubber material or the like at the tip (lower end), and is sucked onto the surface of the bus bar BB by a negative pressure. A tube connection port for supplying negative pressure to the upper end portion is provided, and the tube connected thereto is connected to a negative pressure supply device (not shown) such as a vacuum pump.

  The support plate 72 is formed by bending a belt-shaped plate material made of a metal material or the like into a substantially U-shape when viewed from the front. The suction pad 71 is attached to the lower end portion, and the copying device 73 is attached to the upper end portion.

  The copying apparatus 73 includes an adjustment cylinder 731, a bracket 732, a roller 733, and the like.

  The adjustment cylinder 731 is for moving the suction pad 71 slightly in the vertical direction, and the lot is normally contracted, but the rod is extended and moved by supplying compressed air to the port provided at the lower end. It is a single acting type. A double-acting type may be used. The stroke of the adjusting cylinder 731 is, for example, about several millimeters.

  The adjustment cylinder 731 has a rod end attached to the upper end of the support plate 72 and a bracket 732 attached to the outer periphery of the cylinder tube.

  The bracket 732 is formed by bending a belt-like plate material into a substantially L shape in a side view, and as described above, the upper surface is attached to the outer periphery of the cylinder tube, and the roller 733 is attached to the lower end portion of the side surface.

The roller 733 rotates in contact with the cam surface 51 provided on the upper end surface of the moving block 14. For example, a cam follower is used as the roller 733. As the moving block 14 moves, the height of the cam surface 51 changes, and the roller 733 moves up and down accordingly. When the roller 733 moves up and down, the bracket 732, the adjustment cylinder 731 and the support plate 72 move up and down integrally.
. The support guide 74 includes two support blocks 741 and 741 attached to the substrate 21, a vertically extending guide rod 742 supported by the support blocks 741 and 741, and a slidable slide along the guide rod 742. A block 743 and the like are included.

  The sliding block 743 is attached to a support plate 72, and thus the support plate 72 is supported so as to be movable only in the vertical direction.

  Therefore, the suction pad 71 moves up and down according to the change in the height of the cam surface 51 as the moving block 14 is moved in the horizontal direction by driving the pneumatic cylinder 13.

  When the suction pad 71 sucks the bus bar BB, the roller 733 is on the horizontal surface 51a, and when the claw member 61 approaches the bus bar BB, the roller 733 rises along the inclined surface 51b, and accordingly, the suction pad. 71 rises and starts evacuation. When the claw member 61 reaches the end block 12, the roller 733 reaches the horizontal surface 51c, and the suction pad 71 is retracted to the highest position.

  Next, with reference to FIGS. 5-7, the processing operation by the processing apparatus 1 is demonstrated.

  5 and 6 show the process of starting up the bus bar BB by the processing apparatus 1. FIG. 7 shows the operating state of each part in the process of starting up the bus bar BB. In the following description, FIG. 7 may be referred to for times t0 to t9.

  The processing apparatus 1 stands by at a retracted position with respect to the solar cell main body TD being transported, but when the solar cell main body TD is transported and positioned at the processing station, the processing apparatus 1 is moved by the moving device 17. It is moved and positioned at a predetermined position with respect to the solar cell body TD at time t0.

  That is, the edge part 32 of the end block 12 is positioned in the bending position of the bus bar BB with respect to the solar cell main body TD.

  FIG. 5A shows the initial state of the claw device 15 at time t0.

  As shown in FIG. 5A, the suction pad 71 is in contact with the surface of the front end portion of the bus bar BB, and when negative pressure is supplied at time t1, the suction pad 71 is brought into contact with the front surface portion of the bus bar BB. Adsorb to. In this state, the compressed air is supplied to the port of the adjustment cylinder 731 and the rod is extended, and the suction pad 71 is at the lower end position.

  As shown in FIG. 5B, the supply of compressed air to the adjustment cylinder 731 is interrupted at time t2, and the rod of the adjustment cylinder 731 contracts and moves to the upper end. As a result, the suction pad 71 is slightly lifted to an intermediate position.

  Along with this, at time t3, the tip of the bus bar BB is lifted and slightly lifted from the surface H2 of the solar cell body TD. In the vicinity of time t3, the pneumatic cylinder 13 is driven forward, whereby the claw member 61 moves forward, and the tip 61c of the claw member 61 enters the back side of the bus bar BB.

  As shown in FIG. 5C, as the claw member 61 further moves, the bus bar BB is gradually raised by the workpiece raising surface 61b (near time t4). At this time, the bus bar BB is bent at the edge portion 32 of the end block 12. The suction pad 71 is released from the negative pressure supply at an appropriate timing (after time t3) after the tip 61c of the claw member 61 enters the back side of the bus bar BB. Then, when the roller 733 rises along the inclined surface 51b, the suction pad 71 moves upward and retracts.

  As shown in FIG. 6D, at time t5, the tip portion 61c of the claw member 61 is in contact with the end block 12, and further forward movement is prevented, so that the claw member 61 has a rotation shaft 62. Begins to rotate around.

  As shown in FIG. 6E, the bus bar BB is further bent by the work raising surface 61 b of the claw member 61 by the rotation of the claw member 61. At time t6, the claw member 61 is rotated by approximately 45 degrees, so that the workpiece raising surface 61b is substantially vertical, and the bus bar BB is pressed by the workpiece raising surface 61b and the front side surface 31 of the end block 12. As a result, the bus bar BB is bent substantially at a right angle with the edge portion 32 as the bending position.

  In FIG. 7, the pneumatic cylinder 13 is driven backward at time t7, the claw member 61 moves backward toward the original position, and returns to the original position at time t8.

  At time t9, the processing device 1 is moved by the moving device 17 and retreats to a position where there is no hindrance to the transportation of the solar cell body TD.

  The solar cell body TD that has been bent is unloaded from the processing station, and the next new solar cell body TD is loaded. Thereafter, the operation of the processing apparatus 1 described above is repeated.

  Thus, in the processing apparatus 1 of this embodiment, the suction pad 71 is attracted to the surface of the bus bar BB and moved in a direction away from the surface of the solar cell panel TP, so that the tip of the bus bar BB is moved to the sun. Float from the surface of the battery panel TP. In this state, the claw member 61 moves forward, and the tip 61c enters the back surface of the bus bar BB. As a result, the work raising surface 61b starts raising the bus bar BB.

  And when the front-end | tip part 61c of the nail | claw member 61 contact | abuts directly or indirectly to the end block 12, the nail | claw member 61 will rotate against the urging | biasing force of the coil spring 67, will raise the bus bar BB further, and will bend.

  According to the processing apparatus 1 of this embodiment, a thin plate-like workpiece such as the bus bar BB arranged on the surface of a base material such as the solar cell body TD can be automatically started. Therefore, it is possible to suppress an increase in assembly man-hours or assembly time of the solar battery panel TP. Moreover, it can contribute to the improvement of the yield in production of solar cell panels TP and the stability of quality.

  Further, the bus bar BB is floated from the surface of the solar cell panel TP by the suction pad 71, and the claw member 61 enters the back surface of the bus bar BB in this state, so that the operation is reliable.

  Since the claw member 61 rotates and the work raising surface 61b presses the bus bar BB against the front side surface 31 of the end block 12, the bus bar BB can stand up at a right angle or an arbitrary angle regardless of a simple configuration. it can. Further, by setting the shapes of the front side surface 31 of the end block 12 and the work raising surface 61b of the claw member 61, the bus bar BB can be formed in a predetermined shape.

  In the embodiment described above, the suction pad 71 is moved up and down by a minute distance by the adjusting cylinder 731. According to this, since the independence of the operation of floating the bus bar BB from the surface of the solar cell body TD is increased, the operation timing of each part can be easily adjusted and the operation is reliable.

  However, the suction pad 71 may be moved up and down by a minute distance by omitting the adjustment cylinder 731 and setting the shape of the cam surface 51. In that case, for example, the cam surface 51 may be formed so that the suction pad 71 moves upward before the tip 61c of the claw member 61 reaches the tip of the bus bar BB.

  In the processing apparatus 1 of the embodiment described above, only one claw member 61 is provided and only one bus bar BB is bent. However, two or more claw members 61 are provided. A plurality of bus bars BB may be bent at the same time. Further, instead of the plurality of claw members 61, one long claw member may be provided, and the plurality of bus bars BB may be bent at the same time. In that case, the suction pads 71 may be provided according to the number of bus bars BB.

  Further, in the processing apparatus 1 of the above-described embodiment, when the bus bar BB is sucked by the suction pad 71 and is floated from the solar cell body TD by the adjustment cylinder 731, the suction pad 71 with respect to the surface H2 of the solar cell body TD. Moved vertically. However, strictly speaking, it is preferable that the suction pad 71 moves so as to draw an arc centered on the edge portion 32. However, since the moving distance is very small, there is no problem in practice. However, when the moving distance is increased to some extent, or when the bending distance of the bus bar BB is short, the suction pad 71 moves along an arc along the bending path of the bus bar BB, or is slanted even if it is linear movement It is preferable to move in the direction.

Next, a modified example of such a claw member and a suction pad will be described as a second embodiment.
[Second Embodiment]
10 and 11 show a processing apparatus 1B of the second embodiment. In the processing apparatus 1B of the second embodiment, the description of the parts having the same functions as those of the processing apparatus 1 of the first embodiment is omitted or simplified.

  10 and 11, the processing apparatus 1B is provided with four suction pads 71B and one claw member 61B that is long in the horizontal direction in order to bend four bus bars BB simultaneously.

  That is, in the suction device 16B, the four suction pads 71B are arranged in a line on the support plate 72B with a predetermined interval. The support plate 72B is supported so as to be movable in a slanting vertical direction by a linear guide 721 having an attitude slightly inclined with respect to the vertical direction, and is moved in a slanting vertical direction by an adjustment cylinder 731B arranged in parallel with the linear guide 731. Driven.

  The upper end position and the lower end position of the adjustment cylinder 731B can be adjusted by an adjustment screw 734 provided on the side surface of the adjustment cylinder 731B.

  The axial directions of the linear guide 721 and the adjustment cylinder 731B are close to the movement locus of the tip when the bus bar BB sucked by the suction pad 71B is bent.

  When the adjustment cylinder 731B moves upward while the bus bar BB is sucked by the suction pad 71B, the tip of the suction pad 71B rises substantially along the locus of the tip when the bus bar BB is bent.

  The adjustment cylinder 731B itself is supported by the support guide 74B so as to be movable in the vertical direction, and the height in the vertical direction is varied by the copying apparatus 73B.

  That is, the support guide 74B includes a guide rail 742B attached to the substrate 21B and a sliding block 743B that can slide along the guide rail 742B. The adjusting cylinder 731B is attached to the sliding block 743B via members 744 and 745, and these move together.

  A roller 733B is attached to the member 744 via a bracket 732B, and the roller 733B rolls along the cam surface 51B provided on the moving block 14B.

  Therefore, when the moving block 14B is driven to move in the horizontal direction by a pneumatic cylinder (not shown), the height position of the roller 733B changes according to the change in the height of the cam surface 51B, and the height of the suction surface of the suction device 16B. The position changes.

  The claw device 15B includes a claw member 61B, a rotation shaft 62B, a rotation original position adjusting device 64B, a support portion 65, and the like.

  The support part 65 has two rods 651 and 652 and two side plates 653 and 654 supported by them.

  The claw member 61B is rotatably supported by the rotation shafts 62B provided on the two side plates 653 and 654, respectively. The claw member 61B has a length that sufficiently covers the four bus bars BB arranged on the solar cell body TD. The tip 61Bc of the claw member 61B can enter the back surface of the four bus bars BB at the same time, and the four bus bars BB can be raised at the same time by the work raising surface 61Bb.

  One long end block 12B is provided so as to correspond to the bending positions of the four bus bars BB.

  The rotation original position adjusting device 64B is provided outside the one rotation shaft 62B in order to define the original position of the claw member 61B. A coil spring 67B is attached to the rotation shaft 62B between the side plate 653 and the rotation original position adjusting device 64B, and the rotation original position adjusting device 64 is biased so as to contact the tip of the adjustment screw 66B in a free state. Has been. As a result, the claw member 61B returns to the original position shown in FIGS. 10 and 11 in the free state.

  In the processing apparatus 1B of the second embodiment, the four bus bars BB arranged on the surface of the base material such as the solar cell body TD can be automatically started up simultaneously. Therefore, an increase in assembly man-hours or assembly time of the solar cell panel TP can be further suppressed.

  In the embodiment described above, the end block 12 may be attached so that only the portion corresponding to the bending die of the bus bar BB can be replaced.

  In the above-described embodiment, the belt-like bus bar BB is described as an example of the work, but a work having another shape may be used. A plurality of workpieces having different sizes may be provided. The shapes of the cam surfaces 51 and 51B can be variously changed in addition to those described above.

  In addition, the configuration, structure, shape, material, number, arrangement, etc. of each part or the whole of the main body 11, the end block 12, the pneumatic cylinder 13, the moving block 14, the claw device 15, the suction device 16, or the processing device 1 are described in the present invention. It can be appropriately changed in accordance with the gist of
