[0002] With the rapid development of the photovoltaic industry, solar cell technology is evolving towards diversification and high performance. Different types of solar cells often differ in size and thickness, which places higher demands on the compatibility of the support and transportation equipment in the production process. However, traditional solar cell support devices typically support solar cells (i.e., silicon wafers) of fixed specifications, making it difficult to flexibly adapt to the production needs of different specifications of solar cells. This results in frequent changes of support fixtures when switching products on the production line, causing inconvenience in operation, increasing equipment costs, and reducing production efficiency. Summary of the Invention

[0003] The purpose of this application is to provide a variable-pitch solar cell support device that can be used to support solar cells of different sizes, thereby improving production efficiency and reducing costs.

[0043] See Figure 1 , Figure 3 As shown, a variable-pitch battery cell carrier device according to an embodiment of this application is schematically illustrated, which may include: a frame 100, a pair of basket teeth 200, a top plate 300, a variable-pitch mechanism 400, and a bottom plate 500.

[0044] The frame 100 comprises a pair of basket teeth 200, a top plate 300, a pitch-changing mechanism 400, and a bottom plate 500. The top plate 300 is connected above the corresponding pair of basket teeth 200, and the bottom plate 500 is connected below the corresponding pair of basket teeth 200. Each basket tooth 200 is vertically arranged, forming multiple vertically arranged bearing sections 600 between the pair of basket teeth 200. Each bearing section 600 extends horizontally and is used to support the battery cells. At least one basket tooth 200 is slidable, allowing the spacing between the pair of basket teeth 200 to be adjusted. The top of the at least one slidable basket tooth 200 is slidably connected to the top plate 300, and its bottom is slidably connected to the bottom plate 500. The pitch-changing mechanism 400 is connected to the basket teeth 200 that slidably connect the top plate 300 and the bottom plate 500. The pitch-changing mechanism 400 is used to drive the basket teeth 200 connected to it to slide horizontally along the top plate 300 and the bottom plate 500 to adjust the spacing between the pair of basket teeth 200. The variable pitch mechanism 400 can either drive only one basket tooth 200 to slide horizontally, or drive a pair of basket teeth 200 to slide horizontally in opposite directions simultaneously.

[0045] refer to Figure 11 As shown, each bearing interval 600 formed between a pair of basket teeth 200 can hold one solar cell. When the size of the solar cell to be placed changes, such as during product changeover on the production line, refer to... Figure 12 As shown, the variable pitch mechanism 400 drives the connected basket teeth 200 to slide horizontally along the top plate 300 and the bottom plate 500, thereby adjusting the spacing between a pair of basket teeth 200, that is, adjusting the size of each bearing section 600 in the horizontal direction, which is suitable for bearing and placing battery cells of different sizes.

[0046] Therefore, the variable-pitch solar cell carrier device of this application can be used to carry solar cells of different sizes. It has a simple structure, does not require changing the carrier fixture when switching products on the production line, is convenient and quick to operate, improves production efficiency and reduces costs.

[0047] In some embodiments, reference Figure 1 , Figure 11As shown, the frame 100 can adopt a frame structure with a receiving area. A pair of basket teeth 200, a top plate 300, and a bottom plate 500 are all set in the receiving area of ​​the frame 100. The frame 100 is provided with loading and unloading ports 150 corresponding to the pair of basket teeth 200, that is, the loading and unloading ports 150 are formed by openings on one side of the receiving area. The battery cells are placed into the carrier device or removed from the carrier device through the loading and unloading ports 150. The pitch-changing mechanism 400 can also be set in the frame 100 and installed on the lower surface of the top plate 300. As a result, the structure is more stable and has higher safety and reliability.

[0048] In some embodiments, reference Figures 1-4 As shown, the tops of a pair of basket teeth 200 are respectively connected to a top plate 300. An adjustment assembly for adjusting the height of the top plate 300 relative to the bottom plate 500 is provided on the frame 100. A pitch-changing mechanism 400 works synchronously with the top plate 300. Each basket tooth 200 includes a telescopic mechanism 230. The height of the top plate 300 relative to the bottom plate 500 is adjusted by raising and lowering the top plate, thereby driving the two telescopic mechanisms 230 to extend and retract, adjusting the vertical dimension of each load-bearing section 600. The pitch-changing mechanism 400 can be mounted on the top plate 300, and the load-bearing sections 600 are formed between the telescopic mechanisms 230 of the two basket teeth 200.

[0049] When the thickness of the solar cells to be supported changes, the height of the top plate 300 relative to the bottom plate 500 is adjusted by adjusting the components, referring to... Figure 13 , Figure 14 As shown, the pitch-changing mechanism 400 rises and falls synchronously with the top plate 300. As the top plate 300 rises and falls relative to the bottom plate 500, the top plate 300 drives the telescopic mechanism 230 of a pair of basket teeth 200 to extend and retract synchronously. The synchronous extension and retraction of the two telescopic mechanisms 230 allows the vertical dimension of each load-bearing section 600 to be adjusted synchronously, thus adapting to the load-bearing of solar cells of different thicknesses. Therefore, by adjusting the components, the height of the top plate 300 relative to the bottom plate 500 can be adjusted, causing the telescopic mechanism 230 of the pair of basket teeth 200 to extend and retract synchronously, simultaneously adjusting the vertical dimension of each load-bearing section 600. Furthermore, the pitch-changing mechanism 400 rises and falls synchronously with the top plate 300, allowing adjustment of the spacing between the pair of basket teeth 200, thereby adapting to the load-bearing of solar cells of different sizes and thicknesses. This makes operation more convenient and flexible, further improving production efficiency and reducing costs.

[0050] In some embodiments, reference Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, the adjustment assembly may include a lifting rod 330 and a locking member 140. The lifting rod 330 is mounted on the top plate 300. The frame 100 has a first slide rail 110 and multiple adjustment through holes 130 arranged vertically. The lifting rod 330 is slidably connected to the first slide rail 110. The top plate 300 has connection holes 360 corresponding to the adjustment through holes 130. The locking member 140 passes through the corresponding adjustment through holes 130 and connection holes 360 to lock the top plate 300 to the frame 100. The top plate 300 is located between two side plates of the frame 100. A pair of basket teeth 200 and a bottom plate 500 are also located between the two side plates. Lifting rods 330 can be mounted on both ends of the top plate 300. Each side plate has a first slide rail 110 and multiple adjustment through holes 130. The adjustment through holes 130 and connection holes 360 can be threaded holes, and the locking member 140 can be a screw. The end of each lifting rod 330 away from the top plate 300 extends out of the frame 100 through its corresponding first slide rail 110, so that the lifting rod 330 can be lifted to raise or lower the top plate 300 relative to the bottom plate 500.

[0051] The top plate 300 is locked to the frame 100 by the locking member 140. When it is necessary to adjust the height of the top plate 300 relative to the bottom plate 500, the locking member 140 is released from its connection with the top plate 300. Then, the lifting rod 330 is pulled up and down along the first slide rail 110. After the top plate 300 moves to the required height and the connecting hole 360 ​​aligns with the corresponding adjustment through hole 130, the locking member 140 passes through the adjustment through hole 130 and the connecting hole 360, and the top plate 300 is locked again. By raising and lowering the top plate 300 relative to the bottom plate 500, the telescopic mechanism 230 of a pair of basket teeth 200 extends and retracts synchronously, adjusting the vertical dimension of each bearing section 600, which is suitable for bearing battery cells of different thicknesses. Thus, the structure is simple and stable, the operation is convenient and quick, and the efficiency is improved. In addition, the adjustment component can also adopt other lifting mechanisms such as hydraulic cylinders, electric cylinders, and linear modules.

[0052] Optionally, refer to Figure 2 As shown, a lifting scale 120 is provided on the outer wall of the frame 100. The lifting scale 120 is vertically positioned on one side of the first slide rail 110, and a first indicator arrow 340 corresponding to the lifting scale 120 is provided on the lifting rod 330. This allows for more precise determination of the position and lifting distance of the top plate 300, improving adjustment accuracy and efficiency.

[0053] In some embodiments, reference Figure 1 , Figure 3 , Figure 9 , Figure 10As shown, each basket tooth 200 further includes an upper connecting plate 210 and a lower connecting plate 220. The upper connecting plate 210 is connected above the telescopic mechanism 230 and is used to connect with the top plate 300. The lower connecting plate 220 is connected below the telescopic mechanism 230 and is used to connect with the bottom plate 500. Furthermore, at least one slidable basket tooth 200 includes an upper connecting plate 210 that is slidably connected to the top plate 300 and a lower connecting plate 220 that is slidably connected to the bottom plate 500. It should be noted that if the variable pitch mechanism 400 drives only one basket tooth 200 to slide horizontally, then the upper connecting plate 210 of that basket tooth 200 is slidably connected to the top plate 300 and its lower connecting plate 220 is slidably connected to the bottom plate 500, and the upper connecting plate 210 of the other basket tooth 200 is connected to the top plate 300 and its lower connecting plate 220 is connected to the bottom plate 500. If the variable pitch mechanism 400 drives a pair of basket teeth 200 to slide horizontally in opposite directions simultaneously, then the upper connecting plates 210 of both basket teeth 200 are slidably connected to the top plate 300 and their lower connecting plates 220 are slidably connected to the bottom plate 500. This makes operation more convenient and the structure more stable.

[0054] In some embodiments, reference Figure 3 , Figure 10 As shown, the telescopic mechanism 230 has multiple telescopic hinge points and multiple telescopic units between adjacent hinge points arranged vertically. Each hinge point is connected to a support panel 240, and each support panel 240 is arranged horizontally. The spacing between two adjacent support panels 240 is equal, and the sum of the spacings between all support panels 240 is determined by the height of the top plate 300 relative to the bottom plate 500. Each support panel 240 forms the edge of the bearing section 600. The height of the top plate 300 relative to the bottom plate 500 is adjusted by raising and lowering it, driving each telescopic unit to extend and retract vertically, thereby synchronously adjusting the spacing between the two adjacent support panels 240. In other words, the two sides of a battery cell are respectively supported and placed between two adjacent support panels 240. As the top plate 300 rises and falls relative to the bottom plate 500, the two telescopic mechanisms 230 extend and retract synchronously, thereby synchronously adjusting the spacing between the two adjacent support panels 240, that is, synchronously adjusting the vertical dimension of each bearing section 600, which is suitable for supporting battery cells of different thicknesses. It should be noted that the telescopic mechanism 230 can be the telescopic device of a folding telescopic gate or the scissor telescopic device of a lifting platform, which will not be described in detail here.

[0055] In some embodiments, reference Figure 5 , Figure 6As shown, the pitch-changing mechanism 400 may include a lead screw 410 and a driving member. The lead screw 410 is threadedly connected to at least one slidable tooth 200. The upper connecting plate 210 of the tooth 200 is provided with a threaded connection hole 212 for threaded connection with the lead screw 410. The axial direction of the lead screw 410 is consistent with the sliding direction of the tooth 200. The driving member is connected to the lead screw 410 and is used to drive the lead screw 410 to rotate so that at least one slidable tooth 200 moves along the axial direction of the lead screw 410. Thus, the tooth 200 is stably driven to move horizontally to adjust the gap between a pair of teeth 200.

[0056] Optionally, refer to Figures 3-9 As shown, the driving component includes a rack 420, and a gear 413 meshing with the rack 420 is mounted on a lead screw 410. The rack 420 is horizontally oriented and its length direction is perpendicular to the axial direction of the lead screw 410. A support platform 350 is mounted on the top plate 300, and a second slide rail 351 slidably connects to the rack 420. The length direction of the second slide rail 351 is consistent with the length direction of the rack 420, and the second slide rail 351 passes through the support platform 350. The support platform 350 has a threaded hole 352 corresponding to one side of the rack 420's length direction and a locking screw 353 threadedly connected to the threaded hole 352. The threaded hole 352 communicates with the second slide rail 351, and the locking screw 353 passes through the threaded hole 352 to lock the rack 420 in place. Figure 7 and Figure 8 As shown, the rack 420 has multiple fastening holes 422 arranged at intervals along its length. One of the fastening holes 422 corresponds to a threaded hole 352. A locking screw 353 passes through the threaded hole 352 and the fastening hole 422 to fix the rack 420. An operating part 421 is provided at one end of the rack 420, and the operating part 421 is located outside the second slide rail 351. The operating part 421 can be a pull rod, and there can be one, two, or more support platforms 350.

[0057] When adjusting the spacing between a pair of rack teeth 200, first loosen the locking screw 352 to disengage it from the fastening hole 422 on the rack 420. Then, push and pull the rack 420 through the operating part 421, causing the rack 420 to slide linearly along the second slide rail 351. The rack 420 drives the gear 413 to rotate, which in turn drives the lead screw 410 to rotate. As the lead screw 410 rotates, the rack teeth 200 move axially along the lead screw 410. Simultaneously, the upper connecting plate 210 of the rack teeth 200 slides along the top plate 300, and the lower connecting plate 220 slides along the bottom plate 500. After the rack teeth 200 have moved to the desired position, the locking screw 353 is passed through another corresponding fastening hole 422 on the rack 420 to lock the rack 420, thus completing the spacing adjustment of the pair of rack teeth 200. Alternatively, a power element such as an electric cylinder or a linear module can be used to drive the rack 420 to reciprocate linearly, and a power element such as a motor can be used to drive the lead screw 410 to rotate.

[0058] Optionally, refer to Figure 4 As shown, a horizontal movement scale 320 is provided on the top plate 300, and the length direction of the horizontal movement scale 320 is consistent with the axis of the lead screw 410. A second indicator arrow 211 corresponding to the horizontal movement scale 320 is provided on the basket tooth 200. This allows for more precise determination of the position and movement distance of the basket tooth 200, improving adjustment accuracy and efficiency. Specifically, the second indicator arrow 211 is provided on the upper connecting plate 210 of the basket tooth 200.

[0059] Optionally, refer to Figures 3-9As shown, the top plate 300 is slidably connected to the top of a pair of basket teeth 200, and the bottom plate 500 is slidably connected to the bottom of a pair of basket teeth 200. The variable pitch mechanism 400 is used to drive the pair of basket teeth 200 to move synchronously in opposite directions. The lead screw 410 is a forward and reverse lead screw, with one end of the lead screw 410 having a forward thread 411 and the other end having a reverse thread 412. The gear 413 is located between the forward thread 411 and the reverse thread 412. The forward thread 411 is threadedly connected to one of the basket teeth 200 in the pair of basket teeth 200, and the reverse thread 412 is threadedly connected to the other basket tooth 200. And / or, a first sliding groove 310 is provided on the top plate 300, and a second sliding groove 510 is provided on the bottom plate 500. The length direction of the first sliding groove 310 and the second sliding groove 510 is consistent with the sliding direction of the basket teeth 200.
