Usually, the prism section is laid on the front of one of the two adjacent battery cells, the flat section is laid on the back of the other of the two adjacent battery cells, and the transition section is set between the two adjacent battery cells. The production of triangular special-shaped welding tape is to roll the welding tape into sections and cut them. Due to the error of the triangular special-shaped welding tape itself and the deviation of the hand-pulling tape, the transition sections of the multiple parallel triangular special-shaped welding tapes output from multiple welding tape rolls are usually not in a straight line before cutting, so it is necessary to adjust the multiple transition sections to align them in the same straight line.

In the above method, the installation position of the visual mechanism must avoid strong light, and a fill light is required to assist in cooperation. At the same time, an adjustment mechanism equal to the number of triangular special-shaped welding strips is required, which leads to a complex structure and occupies a large space.

[0027] Specifically, the tape cutting mechanism 300 and the pushing mechanism 600 are respectively arranged at the two ends of the base 100, the driving end of the pushing mechanism 600 is connected to the tape carrier 200, the tape carrier 200 and the base 100 are slidably matched, the first pressing mechanism 400 is arranged at the tape outlet end of the base 100, along the tape supply direction, the limiting mechanism 700 and the second pressing mechanism 500 are sequentially arranged on the tape carrier 200 at intervals, the limiting mechanism 700 is adjacent to the tape feed end of the tape carrier 200, the limiting mechanism 700 is used to limit the triangular welding tape group along the tape supply direction, and the first pressing mechanism 400 and the second pressing mechanism 500 are both used to press the triangular welding tape group.

[0028] During the use of the triangular welding tape pulling device, the process includes a pulling stage, a trimming stage and a feeding stage which are performed in sequence. In the pulling stage, the triangular welding tape groups are pulled to a preset length of the tape outlet end extending out of the base 100, the first pressing mechanism 400 and / or the second pressing mechanism 500 press the triangular welding tape group, the limiting end of the limiting mechanism 700 is away from the triangular welding tape, and the tape cutting mechanism 300 cuts the triangular welding tape group; in the trimming stage, the limiting mechanism 700 cooperates with the triangular welding tape group in a limiting manner along the tape supply direction, the first pressing mechanism 400 is away from the triangular welding tape group, and the second pressing mechanism 500 presses the triangular welding tape group.

[0029] The above structure realizes the alignment function of the triangular welding strip group after cutting through the cooperation of the first pressing mechanism 400, the second pressing mechanism 500, the pushing mechanism 600 and the limiting mechanism 700, thereby avoiding the complexity of structure and action caused by setting up multiple groups of adjustment mechanisms and reducing space occupancy.

[0030] In an embodiment of the present application, the limiting mechanism 700 may include a first driving member 710 and a plurality of limiting forks 720. Specifically, the first driving member 710 is arranged on the carrier 200, and the plurality of limiting forks 720 are all connected to the driving end of the first driving member 710. Any one of the plurality of limiting forks 720 is provided with a first limiting groove and a second limiting groove in sequence along the direction of gravity, and the groove width of the first limiting groove is smaller than the groove width of the second limiting groove.

[0033] Among them, the second driving member 410 can be an electric cylinder, a motor, etc., and this application does not impose any restrictions on this. Optionally, the second driving member 410 can be a cylinder with multiple output ends, and multiple first pressing columns 420 are connected to the multiple output ends one by one, thereby avoiding the complication of the structure caused by setting up multiple drives.

[0034] In the embodiment of the present application, the second pressing mechanism 500 may include a third driving member 510 and a plurality of second pressing columns 520 . The third driving member 510 is disposed on the carrier 200 , and the plurality of second pressing columns 520 are all connected to the driving end of the third driving member 510 .

[0035] In addition, the third driving member 510 can be a cylinder, an electric cylinder, a motor, etc., and this application does not impose any limitation on this.

[0036] In an embodiment of the present application, the carrier 200 may be provided with a plurality of grooves arranged in an array, and the plurality of grooves are used to limit the cooperation with the plurality of triangular welding strips in the triangular welding strip group one by one along their width direction, thereby preventing the triangular welding strip group from being skewed, misaligned, etc. during the conveying process.

[0037] In an embodiment of the present application, when the tape cutting mechanism 300 cuts the triangular welding tape group, the first pressing mechanism 400 and the second pressing mechanism 500 both press the triangular welding tape group, wherein each triangular welding tape in the triangular welding tape group is fixed at two different positions to improve the relative displacement that will not be affected by the cutting force during cutting.

[0038] In the embodiment of the present application, the tape cutting mechanism 300 may include a cutting knife 310, a transmission arm 320, a driving motor 330 and an eccentric shaft 340.

Since the middle section of the transmission arm 320 is hingedly connected to the base 100, one end of the transmission arm 320 drives the cutting knife 310 to reciprocate to achieve cutting of the triangular welding tape group.

[0039] In a further technical solution, one end of the transmission arm 320 can be hingedly connected to one end of the cutting knife 310. An elastic member is provided at one end of the transmission arm 320, and the top rod of the elastic member abuts against one end of the cutting knife 310, thereby preventing the cutting knife 310 and one end of the transmission arm 320 from being fixedly connected and frequently cut, causing fatigue deformation at the connection position, thereby avoiding poor cutting effect. The hinged connection allows the connection position of the cutting knife 310 and the transmission arm 320 to enable the cutting knife 310 to move along the cutting direction for cutting.

[0040] In the embodiment of the present application, the disclosed triangular welding tape pulling device may further include a pulling hand 800 . Specifically, the pulling hand 800 may reciprocate relative to the tape outlet end of the base 100 .
