A first motor 20 is fixedly installed at one end of the fixed device 2, and the output end of the first motor 20 is fixedly connected to the main shaft 21. A first gear 23 is fixedly sleeved on the outer surface of the main shaft 21, and a second gear 24 is fixedly sleeved on the outer surface of the secondary shaft 22. A movable shaft 25 is fixedly provided at one end of the first gear 23 and the second gear 24. The outer surface of the first gear 23 is meshed with the outer surface of the second gear 24. Two connecting rods 26 are rotatably provided at one end of the support plate 1. The outer surfaces of the two connecting rods 26 are provided with a first through groove 27 and a second through groove 28, and the two movable shafts 25 are respectively inserted and connected with the two first through grooves 27. A sliding plate 29 is slidably provided between the inner walls of the two slide rails 11, and a clamping plate is fixedly provided at one end of the two sliding plates 29. 290, the outer surface of the clamping plate 290 located above is fixedly connected to the electric slide rail 6, and one end of the two sliding plates 29 is inserted and connected with the second through groove 28. After positioning and calibrating the battery cell, the battery cell is laser cut, and the first motor 20 in the fixing device 2 is started. The output end of the first motor 20 drives the first gear 23 to rotate, thereby driving the second gear 24 meshing with the first gear 23 to perform synchronous rotation. The two movable shafts 25 at one end of the rotating first gear 23 and the second gear 24 synchronously perform eccentric rotation at one end of the first gear 23 and the second gear 24, thereby driving the two connecting rods 26 to move up and down along the inner surfaces of the two slide rails 11 along with the sliding plates 29 connected thereto, and the first gear 23 and the movable shaft 25 at one end of the second gear 24 move back and forth along the first through groove 27, and the force of the two sliding plates 29 moving up and down drives one end of the sliding plate 29 to slide repeatedly along the two second through grooves 28. When the two movable shafts 25 rotate to a certain extent, the two connecting rods 26 are parallel, so that the two clamping plates 290 at one end of the two sliding plates 29 are clamped and fixed. At this time, the laser cutting machine 8 at one end of the upper clamping plate 290 can perform horizontal cutting movement on the battery panel through the electric slide rail 6 and the electric slider 7. When the first gear 23 and the second gear 24 continue to rotate, the two clamping plates 290 are separated, and the separated battery cells are transported by the second belt 5, thereby achieving the purpose of clamping, fixing and cutting.
[0018] The two connecting rods 26, the sliding plate 29, the slide rail 11, and the clamping plate 290 are all distributed in a mirror image, and the two slide rails 11, the sliding plate 29, and the clamping plate 290 are all on the same vertical horizontal line. The outer surface of one end of the two sliding plates 29 slides in contact with the inner surface of the slide rail 11. The purpose is to facilitate the first gear 23 and the second gear 24 to synchronously drive the two connecting rods 26 to perform eccentric movement, thereby facilitating the two sliding plates 29 and the clamping plate 290 to perform an engagement and positioning movement on the same horizontal line along the two slide rails 11.
[0019] The first gear 23 and the second gear 24 have the same diameter, and the two movable shafts 25 are respectively located at the eccentric parts of the first gear 23 and the second gear 24. The diameters of the first gear 23 and the second gear 24 are the same as the lengths of the two first through grooves 27. The intersection of the first gear 23 and the second gear 24 is on the same horizontal line as the intersection of the two clamping plates 290. This is done to facilitate the two movable shafts 25 to perform eccentric rotational motion of the same amplitude, thereby driving the two connecting rods 26 to swing up and down. When the first gear 23 drives the second gear 24 to rotate to a certain extent, the two clamping plates 290 intersect, thereby achieving the effect of consistent clamping force of the two clamping plates 290.
[0020] The height of the first belt 4 and the second belt 5 is level with that of the positioning device 3, so that the battery cell can fit into the top surface of the positioning device 3 when passing through the groove 12, so that the positioning device 3 can fit and position the battery panel, and then facilitate more accurate cutting.
[0021] Example 2: Figure 4 As shown, the positioning device 3 includes a fixed block 31, the bottom end of the fixed block 31 is fixedly connected to the lower inner wall of the support plate 1, a slide groove 35 is provided at one end of the fixed block 31, a fixed plate 32 is fixedly provided on one side of the top of the fixed block 31, a positioning plate 33 is provided on the other side of the top of the fixed block 31, a slot 34 is provided at one end of the positioning plate 33, a slider 36 is fixedly connected to the bottom end of the positioning plate 33, and the slider 36 is located in the slide groove 35, a threaded rod 37 is connected to the inner surface of the slider 36 by a thread, and one end of the threaded rod 37 is rotatably connected to the inner wall of one side of the slide groove 35, and a second electric The output end of the second motor 38 is fixedly connected to the threaded rod 37. When the solar cell is transmitted to the groove 12 between the support plates 1 through the first belt 4, the second motor 38 in the positioning device 3 is started, and the output end of the second motor 38 rotates, thereby driving the threaded rod 37 to rotate. The rotating threaded rod 37 drives the slider 36 to slide horizontally along the inner wall of the slide groove 35, thereby driving the positioning plate 33 to move horizontally toward the fixed plate 32. The card slot 34 in the positioning plate 33 performs carding correction on the battery cell to facilitate the subsequent laser cutting of the battery cell, thereby achieving the purpose of positioning and calibrating the solar cell.
[0022] Working principle: When the solar cell is transferred to the slot 12 between the support plates 1 via the first belt 4, the second motor 38 in the positioning device 3 is started, and the output end of the second motor 38 rotates, thereby driving the threaded rod 37 to rotate, and the rotating threaded rod 37 drives the slider 36 to slide horizontally along the inner wall of the slide slot 35, thereby driving the positioning plate 33 to move horizontally toward the fixed plate 32, and the card slot 34 in the positioning plate 33 performs carding correction on the cell to facilitate the subsequent laser cutting of the cell, thereby achieving the function of positioning and calibrating the solar cell;
[0023] After positioning and calibrating the battery cell, the battery cell is laser cut, and the first motor 20 in the fixing device 2 is started. The output end of the first motor 20 drives the first gear 23 to rotate, thereby driving the second gear 24 meshing with the first gear 23 to perform synchronous rotational motion, and the two movable shafts 25 at one end of the rotating first gear 23 and the second gear 24 synchronously perform eccentric rotational motion at one end of the first gear 23 and the second gear 24, thereby driving the two connecting rods 26 to move up and down along the inner surfaces of the two slide rails 11 along with the sliding plates 29 connected thereto, and the movable shafts 25 at one end of the first gear 23 and the second gear 24 reciprocate and circulate along the first through groove 27, and the force of the up and down movement of the two sliding plates 29 drives one end of the sliding plate 29 to slide repeatedly along the two second through grooves 28;
[0024] When the two movable shafts 25 rotate to a certain extent, the two connecting rods 26 are parallel, so that the two clamping plates 290 at one end of the two sliding plates 29 are clamped and fixed. At this time, the laser cutting machine 8 at one end of the upper clamping plate 290 can perform horizontal cutting movement on the battery panel through the electric slide rail 6 and the electric slider 7. When the first gear 23 and the second gear 24 continue to rotate, the two clamping plates 290 are separated, and the separated battery cells are transported by the second belt 5, thereby achieving the purpose of clamping, fixing and cutting.

Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
