The laying robot 3 includes a six-axis robot 31 and a busbar suction cup assembly. The busbar suction cup assembly is connected to the six-axis robot. The L-shaped busbar is picked up by the busbar suction cup assembly and placed at a predetermined position on the battery string 4.

[0037] The busbar laying machine of this application embodiment includes a busbar feeding and bending device 2 and a laying robot 3. The busbar feeding and bending device 2 includes an L-shaped feeding and bending module 21, which includes a first busbar feeding mechanism 211, a first busbar pulling mechanism 212, a first busbar cutting mechanism 213, and a first busbar bending mechanism 214. The busbar is fed by the first busbar feeding mechanism 211, then the first busbar pulling mechanism 212 pulls out a busbar of a predetermined length, then the first busbar cutting mechanism 213 cuts the busbar, and finally the first busbar bending mechanism 214 bends the cut busbar into an L-shape. The bent busbar is picked up by the laying robot 3 and placed at a predetermined position on the battery string 4. The busbar feeding and bending device 2 of this application embodiment can realize automatic feeding, cutting and bending of busbars. Compared with the existing manual bending of busbars, it has a high degree of automation, saves labor costs and improves work efficiency.

[0038] In one embodiment, the first busbar feeding mechanism 211 includes a first feeding base 2110, a first feeding tray 2111, and a plurality of first guide wheels 2112. The first feeding tray 2111 and the plurality of first guide wheels 2112 are all rotatably connected to the first feeding base 2110 via a drive shaft. The first feeding tray 2111 can also be driven to rotate by a motor or the like, thereby realizing the feeding of the busbar. A rolled-up busbar is placed on the first feeding tray 2111. The busbar is connected to the plurality of first guide wheels 2112, which guide the busbar, thus feeding it along a predetermined route. The first busbar pulling mechanism 212, the first busbar cutting mechanism 213, and the first busbar bending mechanism 214 are all connected to the first feeding base 2110.

[0039] In another embodiment, the first busbar feeding mechanism 211 may further include a buffer feeding wheel 2113 and a buffer fixing plate, wherein the buffer feeding wheel 2113 and the buffer fixing plate are rotatably connected via a rotating shaft or the like. Simultaneously, two opposing buffer limiting rods 2114 may be fixed on the first feeding base 2110, with the buffer feeding wheel 2113 positioned between the two buffer limiting rods 2114. The buffer fixing plate may be detachably connected to the first feeding base 2110 via bolts or the like, thereby adjusting the position of the buffer feeding wheel 2113 on the first feeding base 2110. The busbar is fed after passing the buffer feeding wheel 2113 and the guide wheel.

[0040] To limit the movement path of the busbar, the first busbar feeding mechanism 211 also includes a first limiting component fixed to the first feeding base 2110. The first limiting component is located on one side of the first busbar cutting mechanism 213. The first limiting component includes a first limiting cylinder 2115, a first limiting block 2116, and a second limiting block 2117. Both the first limiting cylinder 2115 and the second limiting block 2117 are fixed to the first feeding base 2110. The first limiting block 2116 is connected to the first limiting cylinder 2115 and is positioned above the second limiting block 2117. The second limiting block 2117 has a limiting groove, and the opening of the limiting groove faces the first limiting block 2116. When the busbar passes through the limiting groove, the first limiting cylinder 2115 drives the first limiting block 2116 to move downward, thereby preventing the busbar from moving out of the opening of the limiting groove.

[0041] To achieve the clamping of the busbar, the first busbar pulling mechanism 212 includes a first pulling claw 2120 and a first pulling moving assembly 2121. The first pulling claw 2120 is connected to the first pulling moving assembly 2121, and the first pulling moving assembly 2121 drives the first pulling claw 2120 to move. The opening and closing of the first pulling claw 2120 is controlled by a thumb cylinder or the like, thereby achieving the clamping of the busbar. The first pulling moving assembly 2121 can be a belt driven by a motor, or an existing linear module; or it can be a slide rail.

One end of the first pulling moving assembly 2121 is fixed to the first feeding base 2110 by bolts or the like.

[0042] After the first busbar feeding mechanism 211 feeds the busbar, the first busbar pulling mechanism 212 pulls one end of the busbar, and the first pulling component 2121 drives the first pulling claw 2120 to move a certain distance, thereby pulling out the busbar of a predetermined length. Then, the first busbar cutting mechanism 213 cuts the busbar.

[0043] The first busbar cutting mechanism 213 includes a first busbar cutting cylinder 2130, a first busbar cutting base 2131, and a first busbar cutting blade 2132.

The first busbar cutter 2132 can also be an existing cutter 5121 used for cutting busbars. After the busbar passes through the lower part of the first busbar cutting base 2131, one end of the busbar is clamped by the first pull bar gripper 2120 and the busbar of a predetermined length is pulled out. Then, the first busbar cutting cylinder 2130 drives the first busbar cutting blade 2132 to move downward and cuts the busbar through the first busbar cutting blade 2132.

[0045] In one embodiment, the L-shaped feeding and bending module 21 further includes a first busbar straightening mechanism 215, which is used to straighten the busbar.

A first bent base plate 2155 is also fixed on the first busbar alignment base 2151.

[0046] The first busbar alignment rod 2154 is located on one side of the first bending substrate 2155, and multiple alignment stops can be fixed on the other side of the first bending substrate 2155. The first busbar pulling mechanism 212 pulls the busbar and places it on the first bending substrate 2155, then cuts the busbar, and then the first busbar alignment cylinder 2152 drives the first busbar alignment rod 2154 to move towards the busbar, thereby aligning the busbar.

[0047] After the busbar is cut and straightened, the busbar is then bent by the first busbar bending mechanism 214, and the first busbar straightening mechanism 215 is fixed to the first busbar base plate.

A slide rail is also provided on the first bending base plate 21411, and the first gripper fixing plate 21415 is slidably connected to the slide rail. The first pulling cylinder drives the first bending gripper 21414 to slide on the slide rail.

The first bending cylinder 21413 is fixed to the first bending gripper 21414 fixing plate and is connected to the first bending gripper 21414. The first bending cylinder 21413 is a rotary cylinder used to drive the first bending gripper 21414 to rotate.

[0049] The first bending gripper 21414 clamps the busbar at a predetermined position. Then, the first bending cylinder 21413 drives the first bending gripper 21414 to rotate until the busbar is bent at 90 degrees. Next, the first straightening cylinder 21412 drives the first bending gripper 21414 to move away from the first bending substrate 2155, thereby pulling out the bent busbar and bending it into an L-shape. After the busbar is bent, the first pressing cylinder 21402 drives the first pressing block 21403 to move downward and press the bent area, thereby forming the shape.

[0050] In one embodiment, the busbar feeding and bending device 2 further includes a long U-shaped feeding and bending module 21.

[0057] The short U-shaped feeding and bending module 21 includes a third busbar feeding mechanism 231, a third busbar pulling mechanism 232, a third busbar cutting mechanism 233, and a third busbar bending mechanism 234. The third busbar pulling mechanism 232 and the third busbar cutting mechanism 233 are located on one side of the third busbar feeding mechanism 231. The third busbar pulling mechanism 232 is used to pull out a busbar of a predetermined length. The busbar is cut by the third busbar cutting mechanism 233, and the cut busbar is bent into a short U-shape by the third busbar bending mechanism 234.

[0058] The structure and working principle of the short U-shaped feeding and bending module are the same as those of the long U-shaped feeding and bending module 21, and will not be repeated here. Because the U-shaped manifold formed by the long U-shaped feeding and bending module 21 is larger than that formed by the short U-shaped feeding and bending module 21, the short feeding and bending module is smaller and more compact.

[0059] There are two third busbar bending mechanisms 234, which are located at both ends of the third bending substrate. Each third busbar bending mechanism 234 includes a third pressure strip assembly 2341 and a third bending assembly 2342. The ends of the busbar are bent by the two third bending assemblies 2342, and the two third pressure strip assemblies 2341 are used to press the bent ends of the busbar.

[0060] The number of busbar suction cups can be multiple, and each suction cup assembly is used to pick up L-shaped busbars, long U-shaped busbars, and short U-shaped busbars respectively. After picking up the busbars, the suction cup assemblies place them at predetermined positions on the battery string 4. The six-axis robot 31 is an existing robot. The busbar suction cup assembly has multiple suction cups, which pick up the busbars through vacuum adsorption.

[0061] In one embodiment, the busbar laying machine further includes a tape feeding device 5, with the laying robot 3 located between the L-shaped feeding and bending module 21 and the tape feeding device 5. The tape feeding device 5 includes a tape bending mechanism 51, a tape peeling mechanism 52, a tape carrier 53, and a tape transfer mechanism 54. The tape carrier 53 is located on one side of the tape transfer mechanism 54, and the tape bending mechanism 51 and the tape peeling mechanism 52 are located at one end of the tape carrier 53.

[0062] The tape bending mechanism 51 includes a feeding and bending base 510, and a tape feeding tray 511, a tape folding mechanism 513, a tape clamping mechanism 514, and a tape cutting mechanism 512 disposed on the feeding and bending base 510. The tape feeding tray 511 is disposed on the tray base and is rotatably connected to the tray base via a rotating shaft or the like. Rolled tape is placed on the tape tray for feeding. The tape tray can also be rotated by a motor or the like. The tray base is fixed to the feeding and bending base 510, the tape folding mechanism 513 is located at the front end of the tape feeding tray 511, and the tape cutting mechanism 512 is located between the tape folding mechanism 513 and the tape clamping mechanism 514.

[0063] The tape folding mechanism 513 includes a folding moving assembly 5130, folding grippers 5131, and a folding rotating cylinder 5132. The folding rotating cylinder 5132 is connected to the folding moving assembly 5130, and the folding grippers 5131 are connected to the folding rotating cylinder 5132. The folding grippers 5131 can be controlled to open and close by means of a thumb cylinder, thereby gripping the tape. The folding moving assembly 5130 can drive the folding rotating cylinder 5132 to move on a slide rail via an existing ball screw, or the folding moving assembly 5130 can also drive the folding rotating cylinder 5132 to move via a motor driving a belt, etc. The folding moving assembly 5130 drives the folding rotating cylinder 5132 and the folding grippers 5131 to move towards or away from the tape. The two grippers of the folding grippers 5131 can be cylindrical.

[0064] The tape cutting mechanism 512 includes a tape cutting cylinder 5120 and a cutter 5121. The tape cutting cylinder 5120 is fixed on the feeding and bending base 510. The cutter 5121 is connected to the tape cutting cylinder 5120 via a connecting plate or the like, and the tape cutting cylinder 5120 drives the cutter 5121 to move up and down. The cutter 5121 can be any existing cutter 5121 used for cutting tape, and the second cutter 5121 is located below the tape.

[0065] The tape gripping mechanism 514 includes a gripping drive component 5140 and a tape gripper 5141. The gripping drive component 5140 is fixed to the feeding and bending base 510. The gripping drive component 5140 is connected to the tape gripper 5141, and the tape gripper 5141 can also be controlled by a thumb cylinder to open and close. The gripping drive component 5140 drives the tape gripper 5141 to move closer to or further away from the tape. The gripping drive component 5140 can be a cylinder.

[0066] After the tape is fed, the folding jaws 5131 are initially in the open / closed state. The tape passes through the middle of the folding jaws 5131 and is clamped by them. Then, the folding rotary cylinder 5132 drives the folding jaws 5131 to rotate 180 degrees, causing the adhesive side of the tape on both sides of the folding jaws 5131 to adhere, forming a folded surface without adhesive on the tape. After the tape is folded, the tape grippers 5141 clamp the folded position of the tape, simultaneously clamping and compacting the folded area. Next, the folding moving assembly 5130 moves the folding jaws 5131 away from the tape, thereby pulling the folding jaws 5131 out of the tape. Then, the second clamping drive 5140 drives the tape gripper 5141 to move, pulling the tape outward to the predetermined position. Next, the folding moving component 5130 drives the folding gripper 5131 to move towards the tape and return to the working position. Finally, the tape cutting cylinder 5120 drives the cutter 5121 to move upward to cut the tape, thus realizing the folding and cutting of the tape.

[0067] After the tape is cut, the tape transfer mechanism 54 moves the tape to the tape peeling mechanism 52 to peel off the release paper from the tape. The tape transfer mechanism 54 includes a tape transfer assembly 540, a transfer lifting assembly 541, and multiple transfer suction cups 542. The tape lifting assembly is connected to the tape transfer assembly 540, and the multiple transfer suction cups 542 are all connected to the tape lifting assembly. Both the tape transfer assembly 540 and the transfer lifting assembly 541 can be existing linear modules. The transfer suction cups 542 pick up the tape through vacuum adsorption. The number of transfer suction cups 542 can be four.

[0068] After the tape is cut, the tape transfer assembly 540 moves the transfer suction cup 542 above the tape gripper 5141. Then, the transfer lifting assembly 541 moves the transfer suction cup 542 downward, and the transfer suction cup 542 picks up the tape as the tape gripper 5141 releases it. Next, the tape transfer assembly 540 moves the tape to the tape peeling mechanism 52 to peel off the release paper from the tape. This tape peeling machine can be an existing tape peeling machine or tape peeling device; it is existing technology and only needs to be able to peel the tape. The tape peeling machine can also be a manual benchtop peeling machine or a semi-automatic peeling machine, thus facilitating tape peeling.

[0069] After the tape is peeled off, the tape is transferred to the tape carrier 53 by the transfer suction cup 542. In this embodiment, there can be four tape carriers 53, all of which are located on the carrier moving slide rail 55. The tape carriers 53 can be driven by a cylinder to slide on the carrier moving slide rail 55, thereby adjusting the position of the tape carriers 53. The laying robot 3 may also include tape suction cups, and the number of tape suction cups can also be four. The tape suction cups are connected to the six-axis robot 31. After the tape is transferred to the tape carrier 53, the tape suction cups pick up the tape and attach it to the busbar, thereby fixing the L-shaped busbar, the long U-shaped busbar, and the short U-shaped busbar to the glass on the battery string 4.

[0070] The embodiments of this application can automatically bend L-shaped and U-shaped busbars, and can lay and fix the busbars, which improves work efficiency and increases yield.
