Description

Technical Field

[0001] This invention belongs to the field of photovoltaic series return technology, specifically an automatic series return structure that achieves precise positioning. Background Technology

[0002] In the manufacturing process of photovoltaic modules, the string welding of cell strings is one of the core steps. The welding precision and integrity of the cell strings directly determine the power generation efficiency and lifespan of the photovoltaic module. However, affected by various factors such as fluctuations in the precision of production equipment, the stability of the solder ribbon material, and human error, cell strings are prone to defects such as incomplete welding, desoldering, solder ribbon misalignment, and microcracks in the cells after string welding. If these problems are not repaired in time, they will lead to a significant reduction in the power generation performance of the entire photovoltaic module, or even complete scrapping, resulting in serious waste of production costs.

[0003] Traditional photovoltaic (PV) cell string repair work relies heavily on manual labor. Operators must first manually locate the faulty cell string, then use clamps to disassemble it, and after repairing or replacing it on the repair bench, they must manually reposition the cell string back to its original installation position on the PV panel based on their experience. Moreover, manual positioning lacks precise reference points, and the cell string is prone to installation misalignment after repair, which can disrupt the consistency of the internal circuit layout of the PV module and reduce the overall power generation efficiency.

[0068] In this embodiment, the adsorption mechanism further includes: a valve 202, disposed at the upper end of the adsorption head 201, for controlling the opening and closing of the adsorption head 201; an air pipe 203, which is fixedly connected to the valve 202; a fixing frame 204, for supporting the adsorption head 201; a telescopic hose 205, which is slidably disposed on the fixing frame 204, with one end fixedly connected to the air pipe 203; and an air pump 206, disposed on one side of the upper end of the fixing frame 204, for controlling the adsorption of the adsorption head 201, with the other end of the telescopic hose 205 connected to the air inlet of the air pump 206.

[0071] The limiting groove 209 is T-shaped, and the two ends of the fixing plate 207 are T-shaped to fit the limiting groove 209.

[0072] In this embodiment, the specific transposition structure further includes: a support frame 210, fixedly arranged on the main frame 1 for supporting the adsorption mechanism, and a rack 212 fixedly arranged on the support frame 210; a slide groove 211, formed on the support frame 210 for limiting the position of the fixing frame 204, and the fixing frame 204 is slidably connected to the slide groove 211; a spur gear 213 meshing with the rack 212; and a motor 214, located on one side of the fixing frame 204 for driving the spur gear 213 to rotate, and the spur gear 213 is fixedly arranged at the output end of the motor 214.

[0073] It should also be understood that the support frame 210 has two sets, which are respectively located on both sides of the main frame 1.

[0074] In this embodiment, specifically, the support frame 210 is F-shaped.

[0075] In this embodiment, the positioning component further includes: a bolt 302, which is threaded through and connected to the positioning block 301 to limit the movement of the positioning block 301; and positioning scale lines 303, which are set on both sides of the support frame 210 to assist in the precise positioning of the positioning block 301.

[0076] The positioning scale line 303 is provided in two sets, and is respectively set on each set of support frame 210.

[0077] In this embodiment, the transfer assembly specifically includes: a second hydraulic cylinder 401, which is disposed at the bottom of the main frame 1; a pallet 402, which is used to support the photovoltaic panel to be repaired, and the pallet 402 is fixedly arranged at the output end of the second hydraulic cylinder 401; and a guide groove 403, which is opened and arranged on the main frame 1, and the pallet 402 is slidably connected in the guide groove 403.

[0078] It should be noted that the guide groove 403 is cross-shaped, and the bottom of the hydraulic cylinder 401 is cross-shaped to fit the guide groove 403.

[0079] In this embodiment, the specific repair components include: a repair slot 501, which is provided on one side of the main frame 1 for placing the battery string during repair; an auxiliary scale line 502, which is provided in the repair slot 501 for assisting in the positioning of the battery string after disassembly; and a magnetic plate 503, which is magnetically connected in the repair slot 501 for positioning the battery string.

[0080] The auxiliary scale line 502 is cross-shaped, and the magnetic plate 503 is provided in several sets. The magnetic plate 503, together with the auxiliary scale line 502, can accurately position the disassembled, repaired or replaced battery string, making it easy to accurately reset the battery string onto the photovoltaic panel later.

[0081] In this embodiment, specifically: the telescopic hose 205, hydraulic cylinder one 208, motor 214, and hydraulic cylinder two 401 are all electrically connected to the PLC controller.

[0082] Working principle or structural principle: When in use, first place the photovoltaic panel whose battery string needs to be replaced or repaired into the groove on the support plate 402, then turn on the hydraulic cylinder 401. The hydraulic cylinder 401 drives the support plate 402 to slide in the guide groove 403. The support plate 402 can be moved between the two sets of support frames 210.

[0083] After disassembling the battery strings welded onto the photovoltaic panel, motor 214 is turned on, driving spur gear 213 to rotate. Spur gear 213 meshes with rack 212, causing fixed frame 204 to slide on slide groove 211. When fixed frame 204 and suction head 201 are positioned above the disassembled battery strings, motor 214 is turned off, and hydraulic cylinder 208 is activated. Hydraulic cylinder 208 drives fixed plate 207 to slide downwards on limit groove 209. Fixed plate 207 moves several sets of suction heads 201 and... The telescopic hose 205 is pulled, and when the adsorption head 201 is attached to the surface of the battery string, the air pump 206 is turned on. The air pump 206 creates a negative pressure in the adsorption head 201 through the telescopic hose 205 and the air pipe 203 to adsorb the battery string. Then, the hydraulic cylinder 208 is turned on in the opposite direction to drive the adsorbed battery string to the moving height. Each set of adsorption heads 201 is equipped with a set of valves 202. By controlling the opening and closing of the valves 202, the adsorption of the adsorption head 201 can be adjusted according to the position where the battery string needs to be removed.

[0084] When the adsorption head 201 adsorbs, the positioning block 301 slides on the side groove of the support frame 210. When the positioning block 301 is attached to one side of the fixing frame 204, the bolt 302 is turned. The bolt 302 moves downward on the positioning block 301 through the threaded connection. When the bottom of the bolt 302 abuts against the surface of the support frame 210, the fixing is completed. This facilitates the accurate positioning when the fixing frame 204 moves the battery to repair and install it. At the same time, it can be combined with the positioning scale line 303 for auxiliary positioning to further improve the installation positioning accuracy.

[0085] After the battery string is repaired, motor 214 is turned on. When motor 214 moves the fixing frame 204 above the repair slot 501, hydraulic cylinder 208 is turned on to move the battery string adsorbed by the adsorption head 201 downward. When the battery string is attached to the surface of the repair slot 501, several sets of magnetic plates 503 can be adsorbed at a 90-degree angle on both sides of the battery string. Then, air pump 206 is turned on to restore pressure to the adsorption head 201 so that the battery string is detached from the adsorption head 201. When repairing or replacing the battery string in the future, the battery string can be placed in the magnetic plates 503 placed at a 90-degree angle. Then, the adsorption head 201 is controlled to re-adsorb onto the repaired battery string. Then, motor 214 is turned on in reverse to move the fixing frame 204 to attach to the positioning block 301, and hydraulic cylinder 208 is turned on to reset the battery string on the adsorption head 201 to the original position of the photovoltaic panel and weld it.
