[0075] See also Figures 1-1 to 2-4 , a battery cell string welding production equipment of the present invention includes a glue sticking machine 1, a transfer assembly machine 2 and a welding machine 3;

[0076] The gluing machine 1 includes a gluing table 11, the welding machine 3 includes a welding wire table 31, and the transfer assembly machine 2 includes a first bracket 21, a loading mechanism 22, a unloading mechanism 23, a turning mechanism 24 and a finished product conveying line 25. The loading mechanism 22 and the unloading mechanism 23 are both slidably connected to the first bracket 21, the turning mechanism 24 is arranged below the first bracket 21, and the finished product conveying line 25 is arranged below the first bracket 21 and close to the turning mechanism 24. The gluing table 11 moves relative to the first bracket 21, and the welding wire table 31 moves relative to the first bracket 21;

[0077] The unloading mechanism 23 and the turning mechanism 24 both include a plurality of suction components 26 , and each suction component 26 performs flatness correction on each external battery cell finished product 200 ;

[0078] The gluing station 11 is used to carry the external battery cell semi-finished products 100, and the welding wire station 31 is used to carry the external battery cell finished products 200. The loading mechanism 22 transfers the external battery cell semi-finished products 100 located on the gluing station 11 to the welding wire station 31, and the welding machine 3 processes the external battery cell semi-finished products 100 located on the welding wire station 31 into battery cell finished products 200. The unloading mechanism 23 transfers the external battery cell finished products 200 located on the welding wire station 31 to the turning mechanism 24, and the turning mechanism 24 turns over the battery cell finished products 200 and places them on the finished product conveying line 25.

[0079] Specifically, in this embodiment, the transfer assembly machine 2 is located between the gluing machine 1 and the welding machine 3. The external battery cell 101 and the external adhesive strip 102 are processed by the gluing machine 1 to form a battery cell semi-finished product 100. The battery cell semi-finished product 100 is transported to the bottom of the first bracket 21 through the gluing table 11. Then, the loading mechanism 22 absorbs the battery cell semi-finished product 100 and moves it to the top of the welding wire table 31 and places it on the welding wire table 31. After the welding wire table 31 receives the battery cell semi-finished product 100, it moves to the preset station and enters the welding process of the external welding wire and the battery cell semi-finished product 100. The welding machine 3 welds the external welding wire and the battery cell semi-finished product 100 to form a battery cell finished product 200, and then the welding wire table 31 returns to the bottom of the first bracket 21 again. The suction component 26 of the unloading mechanism 23 absorbs the finished battery cell 200 and corrects its flatness. At this time, the suction component 26 of the unloading mechanism 23 absorbs the welding surface of the finished battery cell 200, and the use surface of the finished battery cell 200 faces downward. The unloading mechanism 23 transfers the finished battery cell 200 to the turning mechanism 24. The suction component 26 of the turning mechanism 24 absorbs the lower surface of the finished battery cell 200. At the same time, the suction component 26 corrects the flatness of the finished battery cell 200. Then the turning mechanism 24 flips the suction component 26 180 degrees, so that the welding surface of the finished battery cell 200 faces downward and is placed on the surface of the finished product conveying line 25. The finished battery cell 200 enters the next process through the finished product conveying line 25.

At the same time, under the action of the suction component 26, the flatness of the finished battery cell 200 is corrected synchronously during the transfer process, reducing the space occupied by the equipment, shortening the production cycle, improving production efficiency, and improving the controllability of production quality.

The pressing piece 263 applies downward pressure on the warped part of the finished battery cell 200, and the pulling piece 262 sucks the bent part of the finished battery cell 200 upward to generate an upward pulling force, thereby achieving the problem of correcting the flatness of the finished battery cell 200. At the same time, the pulling piece 262 adopts a vacuum suction structure to achieve the purpose of sucking the finished battery cell 200, meeting the requirements of correction while transporting, shortening the production cycle, and improving production In order to improve production efficiency, preferably, the suction component 26 of the unloading mechanism 23 adopts the following structure: the pulling piece 262 is in the middle of the first mounting plate 261, the number of the pressing pieces 263 is two rows, and the two rows of pressing pieces 263 are respectively located at two opposite sides of the first mounting plate 261, that is, the pulling piece 262 is in the middle of the two rows of pressing pieces 263, and the first flatness correction is performed on the finished battery cell 200; the suction component 26 of the turning mechanism 24 adopts the following structure: the pressing piece 263 is in the middle of the first mounting plate 261, the number of the pulling pieces 262 is two rows, and the two rows of pulling pieces 262 are respectively located at two opposite sides of the first mounting plate 261, that is, the pressing piece 263 is in the middle of the two rows of pulling pieces 262, and the second flatness correction is performed on the finished battery cell 200, thereby further improving the flatness correction quality of the finished battery cell 200.

[0093] The wire supporting assembly 344 includes a second mounting plate 3441, a groove body 3442, an inner supporting member 3443, a second slide 3444 and a second driving member. The second mounting plate 3441 is arranged on the second slide 3444. The second driving member drives the second slide 3444 to move. The groove body 3442 is arranged along the width direction of the second mounting plate 3441 and passes through the second mounting plate 3441. The inner supporting member 3443 is arranged in the groove body 3442. The traction assembly 343 clamps the external welding wire and pulls it out. The main body of the welding wire slides in the groove body 3442. The wire cutting assembly 345 cuts the pulled-out welding wire. The inner supporting member 3443 supports the external welding wire. The second driving member includes a servo motor that drives the second slide 3444 to move horizontally and a servo motor that drives the second mounting plate 3441 to rise and fall. The second mounting plate 3441 moves horizontally and vertically, coordinating with the movement of the wire clamp 3432. As the pulling assembly 343 grips a number of welding wire ends and simultaneously pulls them to a preset length, the main body of the welding wire slides within the trough 3442. The wire cutting assembly 345 then cuts the multiple welding wires into segments of preset lengths, separating the segments from the external welding wire coil and simultaneously forming new ends of the welding wire coil. The second driving member then lowers the second mounting plate 3441, causing the segments to drop onto the upper surface of the external solar cell semi-finished product 100 on the surface of the welding table 31. The new end of the external welding wire coil rests on the inner support 3443 of the trough 3442. The inner support 3443 supports the new end of the welding wire coil, facilitating the re-gripping of the new end of the welding wire coil when the pulling assembly 343 returns to its initial position, thereby shortening the production cycle and reducing energy consumption.

[0094] The inner support member 3443 includes a feed section 34431, a connecting section 34432 and a discharge section 34433. The discharge section 34433 is arranged close to the traction assembly 343. Preferably, the middle section 34432 is connected to the feed section 34431 and the discharge section 34433 in a concave arc shape. The end of the welding wire coil stays in the position of the discharge section 34433. The feed section 34431 supports the main body of the welding wire to prevent the end of the welding wire coil from sliding out of the trough body 3442. The concave arc-shaped middle section 34432 is set to further make the end of the welding wire coil fit into the inner support member 3443, thereby strengthening the supporting purpose.
