Description

Technical Field

[0001] This application belongs to the field of battery processing technology, specifically relating to a movable chuck assembly for a string welding machine. Background Technology

[0002] In recent years, the country has attached increasing importance to the use of clean energy. Among them, the light energy converted by photovoltaic modules is a typical clean energy. Photovoltaic modules are the core of solar power generation systems. Their function is to convert solar energy into electrical energy. The electrical energy can be sent to batteries for storage or used to power loads. Photovoltaic modules are usually made up of layers of backsheet, lower EVA, solar cells, upper EVA and tempered glass, which are then laminated together. The quality of the finished product directly determines the quality of the entire solar power generation system.

[0003] Stringing of solar cells is a crucial processing step. Typically, a robotic arm places the solar cells onto a welding platform, which is then moved to the location where solder strips and a pressure plate are placed. The solder strips are pre-cut and fixed under the pressure pins of the pressure plate, and then moved above the solar cells. The pressure pins on the pressure plate bring the solder strips into contact with and fix them to the solder paste on the solar cell's pads. The welding platform is then moved to the welding position, and a heating lamp melts the solder paste, welding the solder strips to the solar cell's pads. After welding, the pressure plate is removed, resulting in a solar cell string.

[0004] In the current technology, a single robotic arm is usually used in the process of feeding solar cells, which is slow. When a large number of cells need to be fed, multiple robotic arms need to work together. However, multiple separately controlled robotic arms will have some accuracy error, which will cause damage to the solar cells and increase the cost of use.

[0005] Therefore, it is necessary to improve the existing technology to overcome the aforementioned defects. Utility Model Content

[0031] Please see Figures 1 to 4 As shown, a movable chuck assembly for a string welding machine includes a fixed base 1, a first gripper component 2, a fixing component 3, and a second gripper component 4. The fixed base 1 is adapted to be connected to an external robotic arm, and the other components are all connected to the fixed base 1, so that the movement of the robotic arm can drive the entire movable chuck assembly to move.

[0032] In this embodiment, the fixed base 1 is provided with a plurality of first mounting slots 11 at even intervals. The middle part of the first gripper component 2 is rotatably connected to the first mounting slot 11, including a first gripper end 21 extending out of the first mounting slot 11 and a limiting end 22 placed in the first mounting slot 11. One end of the fixed component 3 is connected to the fixed base 1, and the other end covers the connection between the first gripper component and the fixed base 1. The second gripper component 4 can move relative to the fixed base 1 under the action of external force. The fixed base 1 is provided with a movable slot 12 next to each first gripper end 21. The second gripper end 41 of the second gripper component 4 is placed in the movable slot 12 and can move closer to or away from the first gripper end 21 to grip or release the photovoltaic cell to be processed. Thus, by connecting the movable gripper assembly to a robotic arm, several cells to be processed can be gripped at the same time for loading operations. The structure is simple and the cost is low.

[0033] Specifically, in this embodiment, a connecting part 13 is formed on the fixing base 1, and a connecting post 131 is formed on the connecting part 13. The first gripper component 2 has a connecting hole 23 in the middle. The connecting hole 23 is rotatably mounted on the connecting post 131. After the fixing component 3 is connected to the fixing base 1, it is covered on the connecting post 131 to prevent the first gripper component 2 from falling off the connecting post 131.

[0034] To provide space for the first gripper component 2 to move, a moving space 5 is provided between the limiting end 22 of the first gripper component 2 facing the second gripper end 41 and the side wall of the first mounting groove 11. When the first gripper component 2 rotates, the limiting end 22 can move within the moving space 5 and be limited by the side wall of the first mounting groove 11, restricting the angular distance of movement. The movable chuck assembly also includes an elastic element 6 disposed within the moving space 5, thereby providing a force to the first gripper end 21 towards the second gripper end 41 under the elastic force of the elastic element 6, to clamp the battery cell to be processed. In this embodiment, the elastic element 6 is a spring.

[0035] The limiting end 22 has a limiting hole 221 on the side facing the moving space 5, and at least part of the elastic element 6 is placed in the limiting hole 221, thereby preventing the elastic element 6 from falling out of the moving space 5 and increasing stability.

[0036] The second gripper component 4 includes a movable plate 42 that is parallel to and connected to the fixed base 1. Several second gripper ends 41 are evenly spaced and connected to the movable plate 42. The movable plate 42 is connected to an external driving component and can move relative to the fixed base 1 under the drive of the external driving component, thereby realizing the clamping operation.

[0037] It is worth noting that the tips of the first gripper end 21 and the second gripper end 41 protrude from each other to form a clamping end 7, and a shock-absorbing element is attached to the clamping end 7 to prevent the battery cells from being crushed during clamping. In this embodiment, the shock-absorbing element is a rubber pad.

[0038] The fixing component 3 includes a fixing plate 31 and a fixing member 32. The fixing base 1 has a first mounting hole 14, and the fixing plate 31 has a corresponding second mounting hole 311. The fixing member 32 passes through the second mounting hole 311 and is fixed in the first mounting hole 14. In this embodiment, the fixing member 32 is a bolt.

[0039] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the protection scope of this utility model.
