Description

Technical Field

[0001] This application relates to the field of photovoltaic cell module production equipment, and more specifically, to a bus bar picking device. Background Art

[0002] Before implementing bus bar welding, a bus bar preparation device is required to prepare the bus bar. Then, a bus bar picking device picks up the prepared bus bar from the carrier table of the bus bar preparation device, and the bus bar picking device transfers the picked bus bar to the welding table for welding.

[0003] The bus bar picking device includes a moving mechanism, a cantilever, and a plurality of suction cups spaced along the length direction of the cantilever. The moving mechanism drives the cantilever to move, so that the plurality of suction cups cooperate to suck the bus bar on the carrier table and then transport the bus bar to the welding table.

[0004] In the existing bus bar picking device, the suction cups are fixedly arranged on the cantilever. When the level of the carrier table of the bus bar preparation device is insufficient, when the cantilever drives the suction cups to descend towards the carrier table and suck the bus bar, some suction cups may not be able to fully contact and adsorb the bus bar, ultimately resulting in the bus bar not being successfully sucked up or detaching from the suction cups during the transportation process. Utility Model Content

[0005] In order to solve the above technical problems, this application provides a bus bar preparation device, which adopts the following technical solutions:

[0006] A bus bar picking device includes a moving mechanism, a mounting bracket, a cantilever, and at least one adsorption part, wherein:

[0007] The mounting bracket is connected to the moving part of the moving mechanism, and the moving mechanism is used to drive the mounting bracket to translate and lift;

[0008] One end of the cantilever is fixedly connected to the mounting bracket, and the cantilever extends in the horizontal direction;

[0009] The adsorption part includes a plurality of suction cups spaced along the length direction of the cantilever. The plurality of suction cups are used to cooperate to adsorb at least one bus bar, and each suction cup is connected to the cantilever through an independent buffer connecting piece, so that the suction cup can float up and down in the vertical direction.

[0010] The bus bar picking device provided by the present application is used to cooperate with a plurality of suction cups for adsorbing bus bars, and each suction cup is connected to a horizontal cantilever through an independent buffer connecting member. In this way, when the level of the bearing table is insufficient, during the process of the cantilever driving each suction cup to descend towards the bearing table and pick up the bus bar, the suction cup that first contacts the bus bar can float upward relative to the cantilever until all the suction cups fully contact and adsorb the bus bar, and then the cantilever stops descending, so as to ensure that all the suction cups can effectively contact and adsorb the bus bar, ensure the adsorption force of the adsorption part on the bus bar, and prevent the bus bar from detaching from the suction cup during the handling process.

[0011] In some embodiments, the buffer connecting member includes a connecting block, a connecting rod and an elastic member, wherein: the connecting block is fixed on the cantilever, and a plug hole is provided in the connecting block; the connecting rod is inserted into the plug hole in a liftable manner, the lower end of the connecting rod extends downward out of the plug hole, and the suction cup is installed at the lower end of the connecting rod; the elastic member is installed in the plug hole and can elastically deform in the vertical direction, the upper end of the elastic member abuts against the connecting block, and the lower end of the elastic member abuts against the upper end of the connecting rod.

[0012] A buffer connecting member with a simple structure is provided. When the suction cup contacts the bus bar and the cantilever continues to descend towards the bearing table, the elastic member is compressed and contracted, and the suction cup floats upward relative to the cantilever.

[0014] It facilitates the plug-in installation of the connecting rod and ensures that the upper end of the connecting rod remains in the plug hole.

[0015] In some embodiments, an air path extending along the length direction of the cantilever is provided in the cantilever, and the air path is communicated with each suction cup in the adsorption part. An external air extraction device synchronously extracts air from each suction cup in the adsorption part through the air path, so that each suction cup cooperates to adsorb at least one bus bar.

[0016] The unified air extraction of each suction cup in the adsorption part is implemented by the air path provided in the cantilever, and there is no need to use an external air pipe to extract air from the suction cup, thus simplifying the air path layout and avoiding the movement interference of the external air pipe to the cantilever.

[0017] In some embodiments, the air path is communicated with the plug hole, and an air hole for communicating the plug hole and the suction cup is provided in the connecting rod.

[0018] So that the external air extraction device extracts air from the suction cup through the air path, the plug hole and the air hole in sequence, so as to enable the suction cup to generate an adsorption force for adsorbing the bus bar.

[0019] In some embodiments, the bus bar picking device includes two adsorption parts; two air paths corresponding to the two adsorption parts are arranged in the cantilever, and two air extraction devices respectively perform independent air extraction on the two adsorption parts through the two air paths; alternatively, both adsorption parts are communicated with one air path, and the air extraction device performs simultaneous air extraction on the two adsorption parts through the air path.

[0020] Since there are two adsorption parts arranged on the cantilever, and the two adsorption parts perform independent air extraction through their respective corresponding air paths, the bus bar picking device can pick up two sets of bus bars synchronously or successively, and place the picked-up bus bars synchronously or successively at the target position, thereby improving the picking efficiency and flexibility of the bus bars. By connecting both adsorption parts to one air path in the cantilever, only one air extraction device is required to control the two adsorption parts, simplifying the mechanism setting.

[0021] In some embodiments, the mounting bracket includes a driving plate and a rotating plate, wherein: the driving plate is connected to the movable part of the moving mechanism in the vertical direction, and the moving mechanism is used to drive the driving plate to translate and lift; the rotating plate is rotatably mounted on the driving plate in the vertical direction; one end of the cantilever is fixedly connected to the rotating plate.

[0022] One end of the cantilever is fixedly connected to the rotating plate, and the rotating plate is rotatably connected to the driving plate connected to the moving mechanism. By adjusting the mounting angle of the rotating plate, the leveling of the cantilever can be achieved, thereby further ensuring that all suction cups of the adsorption part can effectively contact and adsorb the bus bar.

[0023] In some embodiments, the middle part of the rotating plate is rotatably connected to the driving plate through a rotating shaft; at least one arc-shaped elongated hole is provided on one of the rotating plate and the driving plate, and a connecting screw hole corresponding to the elongated hole is provided on the other of the rotating plate and the driving plate, and the rotating plate is connected to the driving plate through a bolt passing through the elongated hole and the connecting screw hole.

[0024] A simple-structured and convenient-adjusting mounting method of the rotating plate is provided. When the mounting angle of the rotating plate needs to be adjusted, the bolt is loosened, and the rotating plate can be pushed to rotate around the rotating shaft to adjust the mounting angle of the rotating plate. After the mounting angle of the rotating plate is adjusted in place, the bolt is tightened to fix the rotating plate on the driving plate again.

[0025] In some embodiments, a first set screw mounting block and a second set screw mounting block are provided on the driving plate and are located below the rotating plate, where: the first set screw mounting block is disposed near the first end of the rotating plate, and a first set screw is installed in the first set screw mounting block. The first set screw is used to push the rotating plate upward from a first position to drive the rotating plate to rotate around the rotating shaft in a first clockwise direction; the second set screw mounting block is disposed near the second end of the rotating plate, and a second set screw is installed in the second set screw mounting block. The second set screw is used to push the rotating plate upward from a second position to drive the rotating plate to rotate around the rotating shaft in a second clockwise direction.

[0026] By providing the first set screw and the second set screw below the two ends of the rotating plate, flexible adjustment of the angle of the rotating plate is achieved.

[0027] In some embodiments, the moving mechanism includes a translation driving module and a lifting driving module, where: the lifting driving module is connected to the moving part of the translation driving module, and the mounting bracket is connected to the moving part of the lifting driving module; the translation driving module is used to drive the mounting bracket to translate, and the lifting driving module is used to drive the mounting bracket to lift.

[0047] To make the above objects, features and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the accompanying drawings and specific implementation manners.

[0048] As Figure 1 shown, the bus bar picking device in the embodiment of the present application includes a moving mechanism 1, a mounting bracket 2, a cantilever 3 and at least one adsorption part 4, wherein:

[0049] The mounting bracket 2 is connected to the moving part of the moving mechanism 1, and the moving mechanism 1 is used to drive the mounting bracket 2 to translate and lift.

[0050] One end of the cantilever 3 is fixedly connected to the mounting bracket 2, and the cantilever 3 extends in the horizontal direction.

[0051] The adsorption part 4 includes a plurality of suction cups 41 arranged at intervals along the length direction of the cantilever 3. The plurality of suction cups 41 are used to cooperate to adsorb at least one bus bar. Each suction cup 41 is connected to the cantilever 3 through an independent buffer connecting part 42, so that the suction cup 41 can float up and down in the vertical direction.

[0052] In the bus bar picking device according to the embodiment of the present application, several suction cups 41 for adsorbing the bus bar are all connected to the horizontal cantilever 3 through independent buffer connectors 42. In this way, when the flatness of the carrier is insufficient, during the process that the cantilever 3 drives each suction cup 41 to descend towards the carrier and pick up the bus bar, the suction cup 41 that first contacts the bus bar can float upward relative to the cantilever 3 until all the suction cups 41 are in full contact with and adsorbed to the bus bar, and then the cantilever 3 stops descending, so as to ensure that all the suction cups 41 can effectively contact and adsorb the bus bar, ensure the adsorption force of the adsorption part 4 on the bus bar, and prevent the bus bar from detaching from the suction cup 41 during the handling process.

[0053] As Figure 5 and Figure 7 shown, optionally, the buffer connector 42 includes a connection block 421, a connecting rod 422 and an elastic member 423, wherein: the connection block 421 is fixed on the cantilever 3, and a socket hole 424 is provided in the connection block 421. The connecting rod 422 is inserted into the socket hole 424 in a liftable manner, the lower end of the connecting rod 422 extends downward out of the socket hole 424, and the suction cup 41 is installed at the lower end of the connecting rod 422. The elastic member 423 is installed in the socket hole 424 and can elastically deform in the vertical direction. The upper end of the elastic member 423 abuts against the connection block 421, and the lower end of the elastic member 423 abuts against the upper end of the connecting rod 422.

[0054] When the suction cup 41 contacts the bus bar and the cantilever 3 continues to descend towards the carrier, the elastic member 423 is compressed and contracts in the vertical direction, so that the suction cup floats upward relative to the cantilever 3.

[0055] Optionally, the elastic member 423 is a spring.

[0056] Continue to refer to Figure 7 shown, optionally, a limit block 425 is inserted at the lower end of the socket hole 424, and a through hole 426 is provided in the limit block 425. A limit head 427 located in the socket hole 424 is provided at the upper end of the connecting rod 422. The diameter of the limit head is larger than the aperture of the through hole 426, and the connecting rod 422 passes downward through the through hole 426.

[0057] The installation process of the buffer connector 42 and the suction cup 41 is as follows: First, the elastic member 423 is installed into the socket hole 424, and then the upper end of the connecting rod 422 is inserted into the socket hole 424. Then, the limit block 425 is sleeved on the connecting rod 422 from bottom to top, and finally the limit block 425 is inserted into the lower end of the socket hole 424. Finally, the suction cup 41 is installed at the lower end of the connecting rod 422. Of course, the suction cup 41 can also be pre-installed at the lower end of the connecting rod 422 before the upper end of the connecting rod 422 is inserted into the socket hole 424.

[0058] By setting the limit block 425 and arranging a limit head 427 at the upper end of the connecting rod 422, the insertion and installation of the connecting rod 422 are facilitated, and the upper end of the connecting rod 422 is ensured to be limited within the insertion hole 424.

[0059] As Figures � to 7 shown, optionally, an air path 5 extending along the length direction of the cantilever 3 is arranged inside the cantilever 3. The air path 5 is communicated with each suction cup 41 in the adsorption part 4. An external air extraction device synchronously extracts air from each suction cup 41 in the adsorption part 4 through the air path 5, so that each suction cup 41 cooperates to adsorb at least one bus bar.

[0060] The unified air extraction of each suction cup 41 in the adsorption part 4 is implemented by the air path 5 arranged inside the cantilever 3, without using an external air pipe to extract air from the suction cup 41. Therefore, the air path layout is simplified, and the movement interference of the external air pipe to the cantilever 3 is avoided.

[0061] Optionally, the air path 5 is communicated with the insertion hole 424, and an air hole 428 for communicating the insertion hole 424 and the suction cup 41 is arranged inside the connecting rod 422.

[0062] The external air extraction device extracts air from the suction cup 41 in sequence through the air path 5, the insertion hole 424 and the air hole 428, so that the suction cup 41 generates an adsorption force for adsorbing the bus bar.

[0063] Optionally, the bus bar picking device in the embodiment of the present application includes two adsorption parts 4. Two air paths 5 corresponding to the two adsorption parts 4 one by one are arranged inside the cantilever 3. Two air extraction devices respectively extract air from the two adsorption parts 4 independently through the two air paths 5.

[0064] Since two adsorption parts 4 are arranged on the cantilever 3, and the two adsorption parts 4 are independently extracted by their respective corresponding air paths 5. Therefore, the bus bar picking device can pick up two groups of bus bars synchronously or successively, and place the picked-up bus bars to the target position synchronously or successively, thereby improving the bus bar picking efficiency and flexibility.

[0065] Optionally, only one air path 5 is arranged inside the cantilever 3, and both two adsorption parts 4 are communicated with the air path 5. The air extraction device extracts air from the two adsorption parts 4 simultaneously through the air path 5.

[0066] By communicating both two adsorption parts 4 with one air path 5 inside the cantilever 3, only one air extraction device is needed to control the two adsorption parts 4, thus simplifying the mechanism setting.

[0067] Since the cantilever 3 is relatively long, it will tilt after long-term use. When the tilted cantilever 3 drives the suction cups 41 to descend towards the carrier and pick up the bus bar, some of the suction cups 41 on the cantilever 3 may not be able to effectively contact and adsorb the bus bar, ultimately resulting in the bus bar may not be successfully picked up or may break away from the suction cup 41 during the handling process.

[0068] Therefore, as Figures 1 to 4 shown, optionally, the mounting bracket 2 includes a driving plate 21 and a rotating plate 22, where: the driving plate 21 is connected to the moving part of the moving mechanism 1 in the vertical direction, and the moving mechanism 1 is used to drive the driving plate 21 to translate and lift. The rotating plate 22 is rotatably mounted on the driving plate 21 in the vertical direction. One end of the cantilever 3 is fixedly connected to the rotating plate 22.

[0069] Since one end of the cantilever 3 is fixedly connected to the rotating plate 22, and the rotating plate 22 is rotatably connected to the driving plate 21. Before picking up the bus bar, the installation angle of the rotating plate 22 can be adjusted to level the cantilever 3, so that all the suction cups 41 of the adsorption part 4 can effectively contact and adsorb the bus bar, ensuring the adsorption force of the adsorption part 4 on the bus bar and preventing the bus bar from breaking away from the suction cup 41 during the handling process.

[0070] As Figures 2 to 4 shown, optionally, the middle part of the rotating plate 22 is rotatably connected to the driving plate 21 through a rotating shaft 6. At least one arc-shaped elongated hole 7 is provided on the rotating plate 22, and corresponding connecting screw holes 8 are provided on the driving plate 21. The rotating plate 22 is connected to the driving plate 21 through bolts passing through the elongated holes 7 and the connecting screw holes 8. When the installation angle of the rotating plate 22 needs to be adjusted, the bolts can be loosened to push the rotating plate 22 to rotate around the rotating shaft 6 to adjust the installation angle of the rotating plate 22. After the installation angle of the rotating plate 22 is adjusted in place (i.e., the cantilever 3 is leveled), the bolts are tightened to fix the rotating plate 22 to the driving plate 21 again.

[0071] As Figure 4 shown, optionally, four elongated holes 7 are provided on the rotating plate 22, and the four elongated holes 7 are evenly distributed around the rotating shaft 6. Of course, correspondingly, four connecting screw holes 8 are provided on the driving plate 21. By evenly distributing four groups of elongated holes 7 and connecting screw holes 8 around the rotating shaft 6, it is ensured that the rotating plate 22 can be firmly fixed on the driving plate 21 after the rotation adjustment is in place, preventing the rotating plate 22 from accidentally rotating and causing the cantilever 3 to tilt. Of course, one group, two groups, three groups or other numbers of elongated holes 7 and connecting screw holes 8 can also be set.

[0072] In addition, it is also possible to choose to set the elongated holes 7 on the driving plate 21 and the connecting screw holes 8 on the rotating plate 22.

[0073] Optionally, a first setscrew mounting block 9 and a second setscrew mounting block 10 are provided on the driving board 21 and located below the rotating board 22, where: the first setscrew mounting block 9 is provided near the first end (e.g., the left end) of the rotating board 22, and a first setscrew is installed in the first setscrew mounting block 9. The first setscrew is used to push the rotating board 22 upward from the first position to drive the rotating board 22 to rotate around the rotating shaft 6 in the first clockwise direction (e.g., the clockwise direction). The second setscrew mounting block 10 is provided near the second end (e.g., the right end) of the rotating board 22, and a second setscrew is installed in the second setscrew mounting block 10. The second setscrew is used to push the rotating board 22 upward from the second position to drive the rotating board 22 to rotate around the rotating shaft 6 in the second clockwise direction (e.g., the counterclockwise direction).

[0074] It can be seen that through the cooperative adjustment of the first setscrew and the second setscrew, the angle of the rotating board 22 can be flexibly adjusted.

[0075] As Figure 1 shown, optionally, the moving mechanism 1 includes a translation driving module 11 and a lifting driving module 12, where: the lifting driving module 12 is connected to the moving part of the translation driving module 11, and the mounting bracket 2 is connected to the moving part of the lifting driving module 12. The translation driving module 11 is used to drive the mounting bracket 2 to translate, and the lifting driving module 12 is used to drive the mounting bracket 2 to lift.

[0076] Through the cooperation of the translation driving module 11 and the lifting driving module 12, the moving mechanism 1 can drive the mounting bracket 2 to move flexibly in the horizontal and vertical directions, so as to drive the adsorption part 4 to pick up the bus bar and place the picked bus bar at the target position.

[0077] The above has described the present application in sufficient detail with a certain particularity. Those of ordinary skill in the art should understand that the description in the embodiments is only exemplary, and all changes made without departing from the true spirit and scope of the present application should fall within the protection scope of the present application. The scope of protection required by the present application is defined by the claims described, rather than by the above description in the embodiments.
