Description

Technical Field

[0001] This application belongs to the field of battery processing technology, specifically relating to a double-sided ceramic strip suction cup pressing mesh. Background Art

[0002] Photovoltaic modules are the core of a solar power generation system. Their function is to convert solar energy into electrical energy, which can be stored in batteries or used to power loads. Photovoltaic modules are usually laminated together by laying layers of backsheet, lower EVA, solar cells, upper EVA, and tempered glass. 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 existing technology, the two ends of the pressure mesh are usually fixed to the stringing machine with bolts or other hard connections. However, the pressure mesh needs to be removed after each use to collect the welded battery cells. The bolt and other fixed connections are time-consuming and laborious to install and remove, which seriously affects the working efficiency of the stringing machine. Furthermore, the hard connection method will also increase the friction between the pressure mesh and the stringing machine, resulting in faster damage to the pressure mesh.

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

The present utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0036] Please see Figures 1 to 5As shown, a ceramic strip suction cup pressing mesh includes a frame body 1 and a pressing pin assembly 2 connected to the frame body 1. In this embodiment, the frame body 1 is composed of two long sides 11 and two short sides 12 connected end to end in a staggered manner, that is, the entire frame body 1 is rectangular. After the pressing pin assembly 2 is connected to the frame body 1, it is suitable for pressing the welding strip and battery cell to be processed.

[0037] The pressure needle assembly 2 is provided in several groups. The two ends of the pressure needle assembly 2 are connected in parallel to the two short sides 12 of the frame body 1. The pressing mechanism also includes a reinforcing rib component 3. The reinforcing rib component 3 connects two adjacent pressure needle assemblies 2 and the pressure needle assembly 2 near the long side 11 and the long side 11. The material of the long side 11 is ceramic material. The high strength and high wear resistance of ceramic material can extend the service life of the entire pressing mesh. Ceramic also has good heat dissipation, which facilitates heat dissipation of the pressing mesh during and after use.

[0038] In this embodiment, the middle portion of the long side 11 is made of ceramic material, and the portions connecting to the short side 12 at both ends are made of the same 6061 material as the short side 12. This ensures both the strength and wear resistance of the long side 11, and also makes the connection between the long side 11 and the short side 12 more stable and robust due to the consistent material, thus guaranteeing the overall stability of the mesh. In other embodiments, the materials of the long side 11 and the short side 12 of the mesh can be selected according to the actual situation. For example, both the long side 11 and the short side 12 can be made of ceramic in one piece, as long as the actual needs are met. No specific limitation is made here.

[0039] The pressing mesh also includes suction cup assemblies 4 symmetrically arranged on the two short sides 12 and magnetic suction assemblies 5 magnetically fixed to the short sides 12. The suction cup assemblies 4 are pressed and fixed on the short sides 12 by the magnetic suction assemblies 5, so that the entire pressing mesh can be connected to the welding station of the string welding machine by suction cup assemblies 4. It is easy to fix and easy to disassemble. At the same time, since there is a soft suction cup assembly 4 between the pressing mesh and the string welding machine, even if the pressure is high, it will not cause hard friction between the pressing mesh and the string welding machine, effectively extending the service life of the pressing mesh.

[0040] Specifically, the short side 12 is recessed inward to form a first mounting portion 121. The first mounting portion 121 is provided with a positioning docking hole 1211. The suction cup assembly 4 includes a suction cup component 41 and a suction cup seat 42 connected to the suction cup component 41. A positioning post 421 is formed on the suction cup seat 42. The positioning post 421 can extend into and be fixed in the positioning docking hole 1211 to install the suction cup seat 42 in the first mounting portion 121, thereby facilitating the routine maintenance and replacement of the suction cup assembly 4. The suction cup component 41 is made of soft materials such as rubber or silicone.

[0041] In this embodiment, four positioning docking holes 1211 are provided, and the four positioning docking holes 1211 are formed at the four corners of the first mounting part 121. At least two positioning posts 421 are provided, and at least two positioning posts 421 are formed at a set of diagonal points of the suction cup seat 42. This ensures that docking can be completed while maintaining a firm connection, regardless of which direction the suction cup seat 42 is used to dock with the first mounting part 121.

[0042] The magnetic suction assembly 5 includes a fixing plate 51 connected to the short side 12 and a magnetic suction member 52. The material of the short side 12 is a material that can be magnetically attracted, such as iron. The magnetic suction member 52 can use magnetic force to press the fixing plate 51 onto the short side 12 on the side of the fixing plate 51 away from the short side 12. The fixing plate 51 has a through hole 511 at the corresponding position of the first mounting part 121. The suction cup member 41 can pass through the through hole 511 and extend out of the fixing plate 51, so that while the suction cup seat 42 is held in the first mounting part 121, the suction cup member 41 can also be properly attracted.

[0043] The fixing plate 51 has a second mounting portion 512 recessed inward at the center of the side away from the short side 12, and the magnetic suction member 52 can be installed in the second mounting portion 512. Specifically, the bottom of the second mounting portion 512 has a first screw hole 5121, the short side 12 has a corresponding second screw hole 122, and the magnetic suction member 52 has a corresponding third screw hole 521. The pressing mesh also includes a connector 6, which passes sequentially through the third screw hole 521, the first screw hole 5121, and the second screw hole 122 to lock and fix the magnetic suction member 52, the fixing plate 51, and the short side 12. The connection is reinforced by the connector 6 based on the magnetic connection. Alternatively, a corresponding magnetic material can be set on the stringing machine, allowing the magnetic suction member 52 to magnetically attract the pressing mesh by aligning with the magnetic material on the stringing machine when connected, further ensuring the accuracy and stability of the connection between the pressing mesh and the stringing machine. In this embodiment, the connector 6 is a bolt.

[0044] To facilitate the retrieval of the magnetic component 52, in this embodiment, one outer side of the second mounting portion 512 completely penetrates the side wall of the short side 12. The magnetic component 52 is adapted to the shape of the second mounting portion 512. The two corners of the magnetic component 52 away from the outer side have chamfers 522. A gap 7 is formed between the chamfers 522 and the side wall of the second mounting portion 512, so that when retrieving the magnetic component 52, a tool or hand can be inserted into the gap 7 to apply force, making the operation convenient.

[0045] As described above, the pressure needle assembly 2 includes a connecting rod 21 with both ends connected to the short side 12 and a pressure needle component 22 disposed on the connecting rod 21. The pressure needle component 22 can move radially relative to the connecting rod 21, thereby achieving the pressing effect on the welding strip and battery cell to be welded.

[0046] Specifically, first mounting holes 211 are evenly spaced on the connecting rod 21, and the pressure needle component 22 is installed in the first mounting holes 211. The first mounting holes 211 include a first through hole 2111 and a second through hole 2112 connected in the radial direction, and the diameter of the first through hole 2111 is smaller than the diameter of the second through hole 2112. The needle pressing component 22 includes a needle pressing element 221 and a limiting ring 222 sleeved and connected to the needle pressing element. The needle pressing element 221 includes a needle tip 2211 and a needle bar 2212 connected to the needle tip 2211. The needle bar 2212 includes a first rod body 2213 connected to the needle tip 2211 and a second rod body 2214 connected to the first rod body 2213. The limiting ring 222 is sleeved on the second rod body 2214 after it passes through the first mounting hole 211. The diameter of the needle tip 2211 is larger than the diameter of the first through hole 2111, and the diameter of the first rod body 2213 is equal to the diameter of the first through hole 2111. The diameter of the second rod 2214 is equal to the diameter of the second through hole 2112, and the diameter of the limiting ring 222 is greater than the diameter of the second through hole 2112. This allows one end of the needle 2211 to be held outside the first through hole 2111, and the limiting ring 222 to be held outside the second through hole 2112. The length of the needle rod 2212 is greater than the length of the first mounting hole 211, thereby limiting the pressure needle component 22 on the first mounting hole 211. When it is necessary to press the welding strip and the battery cell, only external force is needed to press down the needle 2211, which allows the second rod 2214 to move away from the first mounting hole 211. The end of the second rod 2214 that protrudes from the first mounting hole 211 is recessed inward to form an annular groove 2216. The limiting ring 222 is held and installed in the annular groove 2216. The limiting ring 222 is a copper sleeve.

[0047] To achieve automatic reset of the pressure needle component 22 after clamping, the pressure needle component 22 also includes an elastic element 223. A first step portion 2215 is formed between the first through hole 2111 and the second through hole 2112, and a second step portion 2216 is formed between the first rod body 2213 and the second rod body 2214. The two ends of the elastic element 223 abut against the first step portion 2215 and the second step portion 2216, respectively. When clamping the welding strip and the battery cell, the second step portion 2216 moves towards the first step portion 2215, and the elastic element 223 contracts. After processing, the external force disappears, and the second step portion 2216 can move away from the first step portion 2215 under the elastic action of the elastic element 223, allowing the pressure needle component 221 to achieve automatic reset. In this embodiment, the elastic element 223 is a spring.

[0048] It is worth noting that second mounting holes 111 with the same structure as the first mounting holes 211 are evenly spaced on the long side 11. Pressing needle components 22 are installed in the second mounting holes 111 so that the two long sides 11 serve as two pressing needle assemblies 2, thereby maximizing the processing efficiency of the pressing mesh.

[0049] 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.
