Description

Technical Field

[0001] The present application relates to the field of photovoltaic cell assembly production equipment, and specifically to a strip picking device. Background Art

[0002] Before busbar welding is performed, a busbar picking device is required to pick up the busbar from the carrier platform of the busbar preparation device, and the picked-up busbar is transferred to the welding table for welding.

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

[0004] Since the cantilever is long, it will tilt after long-term use. When the cantilever in the tilted state descends toward the supporting platform with the suction cups to absorb the bus bar, some of the suction cups on the cantilever cannot effectively contact and absorb the bus bar, which may eventually cause the bus bar to fail to be sucked up smoothly or to separate from the suction cups during transportation. Utility Model Content

[0005] In order to solve the above technical problems, the present application provides a strip picking device, which adopts the following technical solutions:

[0006] A strip picking device comprises a moving mechanism, a driving plate, a rotating plate, a cantilever and at least one adsorption portion, wherein:

[0007] 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 move horizontally and up and down;

[0008] The rotating plate is rotatably mounted on the driving plate in a vertical direction;

[0009] One end of the cantilever is fixedly connected to the rotating plate;

[0010] The adsorption portion comprises a plurality of suction cup assemblies spaced apart along the length direction of the cantilever, and the plurality of suction cup assemblies are used for cooperating in adsorbing at least one strip.

[0011] The strip picking device provided in the present application has one end of the cantilever fixedly connected to the rotating plate, and the rotating plate is rotatably connected to the driving plate of the moving mechanism. By adjusting the installation angle of the rotating plate, the cantilever can be leveled, so that all the suction cup components of the adsorption part can implement effective contact adsorption of the strip, ensuring the adsorption strength of the strip by the adsorption part and preventing the strip from detaching from the suction cup component during transportation.

[0012] 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 oblong hole is provided on one of the rotating plate and the driving plate, and connecting screw holes corresponding to the oblong holes one by one are provided on the other of the rotating plate and the driving plate. The rotating plate is connected to the driving plate through bolts passing through the oblong holes and the connecting screw holes.

[0013] A mounting method of the rotating plate with a simple structure and convenient adjustment is provided. When the mounting angle of the rotating plate needs to be adjusted, the bolts are loosened, and then 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 bolts are tightened to fix the rotating plate on the driving plate again.

[0014] In some embodiments, four oblong holes are provided on one of the rotating plate and the driving plate, and the four oblong holes are evenly distributed around the rotating shaft.

[0015] By evenly distributing four groups of oblong holes and connecting screw holes around the rotating shaft, it is ensured that the rotating plate can be firmly fixed on the driving plate after being adjusted in place, preventing the rotating plate from accidentally rotating and causing the cantilever to tilt.

[0016] In some embodiments, a first setscrew mounting block and a second setscrew mounting block are provided on the driving plate and located below the rotating plate, where: the first setscrew mounting block is arranged near the first end of the rotating plate, and a first setscrew is installed in the first setscrew mounting block. The first setscrew is used to push the rotating plate upward from the first position to push the rotating plate to rotate around the rotating shaft in the first clockwise direction; the second setscrew mounting block is arranged near the second end of the rotating plate, and a second setscrew is installed in the second setscrew mounting block. The second setscrew is used to push the rotating plate upward from the second position to push the rotating plate to rotate around the rotating shaft in the second clockwise direction.

[0017] By providing the first setscrew and the second setscrew below the two ends of the rotating plate, flexible adjustment of the angle of the rotating plate is achieved.

[0018] In some embodiments, an air path extending along the length direction of the cantilever is arranged in the cantilever, and the air path is communicated with each suction cup assembly in the adsorption part; an external air extraction device extracts air from each suction cup assembly in the adsorption part through the air path, so that each suction cup assembly cooperates to adsorb at least one strip.

[0019] The unified air extraction of each suction cup assembly in the adsorption part is implemented by the air path arranged in the cantilever, and there is no need to use an external air pipe to extract air from the suction cup assembly, thereby simplifying the air path layout and avoiding the movement interference of the external air pipe to the cantilever.

[0020] In some embodiments, the suction cup assembly includes a mounting block, a connecting rod, and a suction cup, where: the mounting block is fixed on the cantilever, and a first air passage communicating with the air circuit is provided in the mounting block; the connecting rod is mounted on the mounting block, a second air passage communicating with the first air passage is provided in the connecting rod, the suction cup is mounted at the lower end of the connecting rod and communicates with the second air passage, and the suction cup is used for adsorbing the strip.

[0021] By arranging the suction cup assembly, the external air extraction device sequentially extracts air from the suction cup through the air circuit, the first air passage, and the second air passage, so that the suction cup generates an adsorption force for adsorbing the strip.

[0022] In some embodiments, a connector for connecting the air extraction device is provided on the rotating plate, and the connector communicates with the air circuit.

[0023] By providing the connector on the rotating plate, the docking of the air circuit and the air extraction device is realized.

[0024] In some embodiments, the strip picking device includes two adsorption parts, two air circuits corresponding to the two adsorption parts one by one are provided in the cantilever, and two air extraction devices respectively extract air from the two adsorption parts independently through the two air circuits.

[0025] Since two adsorption parts are provided on the cantilever and the two adsorption parts are independently extracted air by their respective corresponding air circuits, the strip picking device can pick up two groups of strips synchronously or successively, and place the picked-up strips to the target position synchronously or successively, thereby improving the strip picking efficiency and flexibility.

[0026] In some embodiments, the strip picking device includes two adsorption parts, both of the two adsorption parts communicate with one air circuit, and the air extraction device extracts air from the two adsorption parts simultaneously through the air circuit.

[0027] By connecting both of the two adsorption parts to one air circuit in the cantilever, only one air extraction device is needed to control the two adsorption parts, which simplifies the mechanism setting.

[0028] 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 driving plate is connected to the moving part of the lifting driving module; the translation driving module is used to drive the driving plate to translate, and the lifting driving module is used to drive the driving plate to lift.

[0029] Through the cooperation of the translation driving module and the lifting driving module, the moving mechanism can drive the driving plate to move flexibly in the horizontal and vertical directions, so as to drive the adsorption part to pick up the strip and place the picked-up strip to the target position.

[0052] To make the above - mentioned 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 embodiments.

[0053] As Figures 1 to 4 shown, the strip - picking device in the embodiment of the present application includes a moving mechanism 1, a driving plate 2, a rotating plate 3, a cantilever 4, and at least one adsorption part 5, where:

[0054] The driving plate 2 is vertically connected to the movable part of the moving mechanism 1, and the moving mechanism 1 is used to drive the driving plate 2 to translate and lift.

[0055] The rotating plate 3 is rotatably mounted on the driving plate 2 in the vertical direction.

[0056] One end of the cantilever 4 is fixedly connected to the rotating plate 3.

[0057] The adsorption part 5 includes a plurality of suction cup assemblies arranged at intervals along the length direction of the cantilever 4, and the plurality of suction cup assemblies are used to cooperate to adsorb at least one strip.

[0058] In the strip - picking device in the embodiment of the present application, one end of the cantilever 4 is fixedly connected to the rotating plate 3, and the rotating plate 3 is rotatably connected to the driving plate of the moving mechanism 1. Before picking up the strip, the installation angle of the rotating plate 3 can be adjusted to level the cantilever 4, so that all the suction cup assemblies of the adsorption part 5 can effectively contact and adsorb the strip, ensuring the adsorption force of the adsorption part 5 on the strip and preventing the strip from detaching from the suction cup assemblies during the handling process.

[0059] The strip - picking device in the embodiment of the present application is suitable for picking up the prepared busbars from the carrier table of the busbar preparation device and transferring the picked - up busbars to the welding table for welding. Of course, it is also suitable for picking up other strip - shaped products.

[0060] As Figures 2 to 4 shown, optionally, the middle part of the rotating plate 3 is rotatably connected to the driving plate 2 through a rotating shaft 6. At least one arc - shaped waist - shaped hole 7 is provided on the rotating plate 3, and connection screw holes 8 corresponding to the waist - shaped holes 7 one by one are provided on the driving plate 2. The rotating plate 3 is connected to the driving plate 2 through bolts passing through the waist - shaped holes 7 and the connection screw holes 8. When the installation angle of the rotating plate 3 needs to be adjusted, the bolts are loosened, and the rotating plate 3 can be pushed to rotate around the rotating shaft 6 to adjust the installation angle of the rotating plate 3. After the installation angle of the rotating plate 3 is adjusted in place (i.e., the cantilever 4 is leveled), the bolts are tightened to fix the rotating plate 3 to the driving plate 4 again.

[0061] As Figure 4As shown, optionally, four oblong holes 7 are provided on the rotating plate 3, and the four oblong holes 7 are evenly distributed around the rotating shaft 6. Correspondingly, four connecting screw holes 8 are provided on the driving plate 2.

[0062] By evenly distributing four groups of oblong holes 7 and connecting screw holes 8 around the rotating shaft 6, it is ensured that the rotating plate 3 can be firmly fixed on the driving plate 3 after the rotation adjustment is in place, preventing the rotating plate 3 from accidentally rotating and causing the cantilever 4 to tilt. Of course, one group, two groups, three groups or other numbers of oblong holes 7 and connecting screw holes 8 can also be set.

[0063] In addition, it is also possible to choose to set the oblong holes 7 on the driving plate 2 and the connecting screw holes 8 on the rotating plate 3.

[0064] Optionally, a first set screw mounting block 9 and a second set screw mounting block 10 are provided on the driving plate 2 and located below the rotating plate 3. Among them: the first set screw mounting block 9 is arranged near the first end (for example, the left end) of the rotating plate 3, and a first set screw is installed in the first set screw mounting block 9. The first set screw is used to push the rotating plate 3 upward from the first position to drive the rotating plate 3 to rotate around the rotating shaft 6 in the first clockwise direction (for example, the clockwise direction). The second set screw mounting block 10 is arranged near the second end (for example, the right end) of the rotating plate 3, and a second set screw is installed in the second set screw mounting block 10. The second set screw is used to push the rotating plate 3 upward from the second position to drive the rotating plate 3 to rotate around the rotating shaft 6 in the second clockwise direction (for example, the counterclockwise direction).

[0065] It can be seen that through the cooperative adjustment of the first set screw and the second set screw, the angle of the rotating plate 3 can be flexibly adjusted.

[0066] As Figures 5 to 7 shown, optionally, an air passage 110 extending along the length direction of the cantilever 4 is provided in the cantilever 4, and the air passage 110 is communicated with each suction cup assembly in the adsorption part 5. An external air extraction device extracts air from each suction cup assembly in the adsorption part 5 through the air passage 110, so that each suction cup assembly cooperates to adsorb at least one strip.

[0067] The unified air extraction of each suction cup assembly in the adsorption part 5 is implemented by the air passage 110 provided in the cantilever 4, without using an external air pipe to extract air from the suction cup assembly, thus simplifying the air passage layout and avoiding the movement interference of the external air pipe to the cantilever 4.

[0068] As Figure 7 shown, the suction cup assembly includes a mounting block 51, a connecting rod 52 and a suction cup 53. Among them: the mounting block 51 is fixed on the cantilever 4, and a first air passage 120 communicated with the air passage 110 is provided in the mounting block 51. The connecting rod 52 is installed on the mounting block 51, a second air passage 130 communicated with the first air passage 120 is provided in the connecting rod 52, and the suction cup 53 is installed at the lower end of the connecting rod 52 and communicated with the second air passage 130.

[0069] The external air extraction device successively extracts air from the suction cup 53 through the air path 110, the first air passage 120, and the second air passage 130. The air flow direction during air extraction is as shown by the arrow direction in Figure 7 to enable the suction cup 53 to generate the adsorption force for the adsorption strip.

[0070] Optionally, a connector 140 for connecting the air extraction device is provided on the rotating plate 3, and the connector 140 is communicated with the air path 110. By providing the connector 140 on the rotating plate 3, the docking of the air path 110 with the air extraction device is realized.

[0071] As shown in Figure 5 and Figure 7 , optionally, the strip picking device in the embodiment of the present application includes two adsorption parts 5. Correspondingly, two air paths 110 corresponding to the two adsorption parts 5 one by one are arranged in the cantilever 4, and two air extraction devices respectively extract air from the two adsorption parts 5 independently through the two air paths 110.

[0072] Since two adsorption parts 5 are arranged on the cantilever 4, and the two adsorption parts 5 are independently extracted air by their respective corresponding air paths 110. Therefore, the strip picking device in the embodiment of the present application can pick up two groups of strips synchronously or successively, and place the picked strips to the target position synchronously or successively, thereby improving the strip picking efficiency and flexibility.

[0073] Optionally, the strip picking device in the embodiment of the present application includes two adsorption parts 5, and the two adsorption parts 5 are both communicated with one air path 110, and the air extraction device extracts air from the two adsorption parts 5 simultaneously through the air path 110.

[0074] By communicating the two adsorption parts 5 with one air path 110 in the cantilever 4, only one air extraction device is needed to control the two adsorption parts 5, which simplifies the mechanism setting.

[0075] As shown in Figure 1 , optionally, the moving mechanism 1 includes a translation driving module 11 and a lifting driving module 12, wherein: the lifting driving module 12 is connected to the moving part of the translation driving module 11, and the driving plate 2 is connected to the moving part of the lifting driving module 12. The translation driving module 11 is used to drive the driving plate 2 to translate, and the lifting driving module 12 is used to drive the driving plate 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 driving plate 2 to move flexibly in the horizontal direction and the vertical direction, so as to drive the adsorption part 5 to pick up the strip and place the picked strip to the target position.

[0077] Both the translation drive module 11 and the lifting drive module 12 can adopt various existing types of linear drive modules, such as synchronous belt drive modules, lead screw drive modules, etc.
