Technical Field

[0001] The utility model relates to the technical field of battery string soldering, in particular to a battery cell string soldering device with a positioning mechanism. Background Technique

[0002] Battery cells are generally divided into single-crystalline silicon, polycrystalline silicon and amorphous silicon. String soldering is one of the battery cell processing techniques, that is, the welding of the positive and negative electrodes of the single-soldered battery cells in series. The soldering body assembly for battery cell string soldering processing usually includes a string soldering template, a soldering iron, etc.

[0003] However, a working platform is provided on one side of the battery cell string soldering device. After placing the string soldering template matching the battery cells on the working platform, the battery cells are placed in the string soldering template in sequence, and then the operator holds a soldering gun and welding wire to perform string soldering operations on the battery cells. When the existing device is in use, due to its own vibration during use, the working platform will have a certain amount of shaking, and some existing devices do not have a limiting and clamping mechanism for the battery cells. As a result, when the operator performs string soldering on the battery cells, due to the shaking of the device itself, the soldering effect and quality on the surface of the battery cells will be affected.

[0004] Therefore, it is very necessary for us to propose a battery cell string soldering device with a positioning mechanism to solve the above problems. Summary of the Utility Model

Through the mutual cooperation between the internal parts of the clamping and limiting mechanism, the battery cells on the surface of the device platform can be clamped and limited, which is convenient for the string soldering of the battery cells, so as to solve the problem that in the prior art, due to the lack of a limiting and clamping mechanism for the battery cells in some existing devices, the shaking or vibration of the battery cell string soldering device itself during use will affect the soldering effect and quality on the surface of the battery cells.

[0006] In order to achieve the above purpose, the utility model provides the following technical solution: A battery cell string soldering device with a positioning mechanism, including a device platform, the top of the device platform is connected with a clamping and limiting mechanism and penetrates into the interior of the device platform, and one side of the device platform is rotatably connected with a reset mechanism and penetrates into the interior of the device platform.

[0007] Preferably, the clamping and limiting mechanism includes a placement mold located at the top of the device platform. A telescopic column is fixedly connected to the bottom of the placement mold and penetrates into the interior of the device platform. A transmission gear is rotatably connected inside the device platform and is located on both sides of the telescopic column. A limiting plate is slidably connected to the side of the transmission gear away from the telescopic column and penetrates through the top of the device platform to one side of the placement mold. Support plates are fixedly connected to both ends of the telescopic column and are located inside the device platform. A telescopic spring is fixedly connected to the bottom of the telescopic column. Connecting shafts are provided at both ends of the placement mold and are rotatably connected to the top of the device platform. Clamping plates are fixedly connected to the tops of the connecting shafts. One-way torsion springs are rotatably sleeved on the outer walls on both sides of the connecting shafts. Fixed plates are fixedly connected to the tops of the ends of the support plates away from the telescopic column and penetrate to the bottom of the connecting shafts.

[0008] Preferably, the reset mechanism includes a transmission shaft fixedly connected to one side of the connecting shaft and rotatably connected inside the device platform. A connecting column is rotatably connected to one side of the device platform, penetrates through the device platform to the interior of the device platform, and is located on the side of the transmission shaft away from the connecting shaft. A torsion block is fixedly connected to the side of the connecting column away from the device platform. A second torsion spring is sleeved on the outer wall of the connecting column and is located inside the device platform. A limiting block is installed at the top of the connecting column and is slidably connected inside the device platform. A contraction spring is fixedly connected to the top of the limiting block. A connecting block is fixedly connected to the side of the connecting column close to the transmission shaft and penetrates into the interior of the transmission shaft.

[0009] Preferably, a telescopic groove matching the telescopic column is opened inside the device platform. Tooth grooves matching the tooth blocks on the outer wall of the transmission gear are opened on the telescopic column and the side of the limiting plate close to the transmission gear. An activity groove matching the support plate is opened inside the device platform.

[0010] Preferably, the connecting shaft is rotatably connected to the device platform through a bearing.

A connecting groove matching the connecting block is opened on one side of the transmission shaft.

[0012] In the above technical solution, the technical effects and advantages provided by the present invention:

[0013] 1. By placing multiple solar cells on the placement mold on the device platform, the placement mold is stressed to drive the telescopic column at the bottom to squeeze the telescopic spring and contract and move. The movement of the telescopic column drives the transmission gear to rotate through the tooth grooves on both sides. The rotation of the transmission gear drives the limit plate to move. The limit plate moves out of the device platform and moves to the top of the device platform, and limits the two sides of the multiple solar cells at the top of the placement mold. At the same time, the movement of the telescopic column drives the support plates at both ends to move, and the movement of the support plates drives the fixed plate to move to release the fixation of the connecting shaft. After the connecting shaft is released from fixation, the first torsion spring is reset to drive the connecting shaft to rotate. The rotation of the connecting shaft drives the clamping plate to rotate, and the clamping plate rotates to clamp the surface of the solar cell at the top of the placement mold. In this way, when the solar cells are string-welded, the welding position will not shift due to the shaking of the device platform, improving the string-welding efficiency and quality of the solar cells;

[0014] 2. By pushing the connecting column to move and driving the connecting block to move into the transmission shaft, then rotating the torsion block, the torsion block drives the connecting column to squeeze the second torsion spring to contract and rotate. The rotation of the connecting column drives the connecting block to rotate, and the rotation of the connecting block drives the transmission shaft to rotate. The rotation of the transmission shaft drives the connecting shaft to rotate, so that the rotation of the connecting shaft drives the clamping plate to rotate to release the clamping operation on the surface of the solar cell at the top of the placement mold. At the same time, the rotation of the connecting column rotates the limit groove to the bottom of the limit block, and the contraction spring is reset to push the limit block to move into the limit groove, completing the rotational fixation of the connecting column. The staff takes out the string-welded solar cells from the top of the placement mold, so that the placement mold drives the telescopic column to release the extrusion of the telescopic spring, and the telescopic spring pushes the telescopic column to reset. The reset of the telescopic column drives the support plate to move, and the movement of the support plate drives the fixed plate to move into the connecting shaft to complete the rotational fixation of the connecting shaft. Then, pull the connecting column. The movement of the connecting column squeezes the limit block through the arc surface at the top, so that the limit block squeezes the contraction spring to contract and move out of the connecting column to release the rotational fixation of the connecting column. At the same time, the movement of the connecting column drives the connecting block and the transmission shaft to separate from each other, and the second torsion spring is reset to drive the connecting column to rotate and reset, so that the internal parts of the clamping and limiting mechanism can repeatedly and conveniently perform the clamping and limiting operation on the solar cells at the top of the placement mold.

[0029] The working principle of this utility model:

[0030] Refer to the attached instructions Figures 1-4 , by placing multiple battery cells on the placement mold 201 on the device platform 1, the placement mold 201 is stressed to drive the telescopic column 202 at the bottom to squeeze the telescopic spring 206 to contract and move. The movement of the telescopic column 202 drives the transmission gear 203 to rotate through the tooth grooves on both sides. The rotation of the transmission gear 203 drives the limiting plate 204 to move. The limiting plate 204 moves out of the device platform 1 and moves to the top of the device platform 1, and performs a limiting operation on both sides of the multiple battery cells at the top of the placement mold 201. At the same time, the movement of the telescopic column 202 drives the support plates 205 at both ends to move. The movement of the support plates 205 drives the fixed plate 207 to move to release the fixation of the connecting shaft 208. After the connecting shaft 208 is released from fixation, the first torsion spring 210 resets to drive the connecting shaft 208 to rotate. The rotation of the connecting shaft 208 drives the clamping plate 209 to rotate. The rotation of the clamping plate 209 performs a clamping operation on the surface of the battery cell at the top of the placement mold 201, so that when the battery cell is series-welded, the welding position will not shift due to the shaking of the device platform 1, improving the series-welding efficiency and quality of the battery cell;

[0031] Refer to the attached instructions Figures 1-4, after the battery cells complete the string welding operation, push the connecting column 301. The movement of the connecting column 301 drives the connecting block 306 to move into the inside of the transmission shaft 307. Then rotate the torsion block 302. The torsion block 302 drives the connecting column 301 to squeeze the second torsion spring 303 to contract and rotate. The rotation of the connecting column 301 drives the connecting block 306 to rotate. The rotation of the connecting block 306 drives the transmission shaft 307 to rotate. The rotation of the transmission shaft 307 drives the connecting shaft 208 to rotate, so that the rotation of the connecting shaft 208 drives the clamping plate 209 to rotate to release the clamping operation on the surface of the battery cell at the top of the placement mold 201. At the same time, the rotation of the connecting column 301 rotates the limit groove to the bottom end of the limit block 305, and the reset of the compression spring 304 pushes the limit block 305 to move into the limit groove to complete the rotational fixation of the connecting column 301. The staff takes out the string-welded battery cells from the top of the placement mold 201, so that the placement mold 201 drives the telescopic column 202 to release the extrusion of the telescopic spring 206. The telescopic spring 206 pushes the telescopic column 202 to reset. The reset of the telescopic column 202 drives the support plate 205 to move. The movement of the support plate 205 drives the fixing plate 207 to move into the inside of the connecting shaft 208 to complete the rotational fixation of the connecting shaft 208. Then pull the connecting column 301. The movement of the connecting column 301 squeezes the limit block 305 through the arc surface at the top, so that the limit block 305 squeezes the compression spring 304 to contract and move out of the connecting column 301 to release the rotational fixation of the connecting column 301. At the same time, the movement of the connecting column 301 drives the connecting block 306 to separate from the transmission shaft 307, and the reset of the second torsion spring 303 drives the connecting column 301 to rotate and reset, so that the parts inside the clamping and limiting mechanism 2 can repeatedly and conveniently perform the clamping and limiting operation on the battery cells at the top of the placement mold 201.

[0032] Only some exemplary embodiments of the present invention are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways.
