[0035] The embodiment provides a processing production line, comprising a battery string processing device. Specifically, referring to Figure 1 , the battery string processing device comprises a support assembly 10, a belt making assembly 20 and a crimping mechanism 30.

[0036] Further, the support assembly 10 comprises a support platform 11 extending along the first direction. In the embodiment, the support platform 11 is provided in a rectangular shape, and a plurality of supporting legs (not shown) are arranged at the bottom of the support platform 11 to stably place the support platform 11 on the ground. Referring to Figure 3 , the strip making assembly 20 comprises a plurality of strip making plates 21 which are fixedly connected to the support platform 11 along the first direction. The surface of the strip making plate 21 is provided with a plurality of solder strip grooves 211 which are uniformly and spacedly arranged along the second direction. The first direction is perpendicular to the second direction. The surface of the strip making plate 21 is used to receive the strip film 2, and the groove wall of the solder strip groove 211 is used to receive the solder strip 1. The solder strip 1 corresponds to the strip film 2. In the embodiment, the strip film 2 can be provided as an adhesive film, and the solder strip 1 is directly pasted on the adhesive film to avoid the relative position deviation between the solder strip 1 and the strip film 2, thereby affecting the quality of the adhesive film bonding. In other embodiments, the strip film 2 can also be provided as a low-flow EVA film. While the strip film 2 adsorbs the solder strip 1, the solder strip 1 can also rely on its own weight to compress the strip film 2. The crimping mechanism 30 comprises a pressing plate assembly 31 which can move along the vertical direction. The pressing plate assembly 31 is located above the strip making assembly 20 and is used to grab and crimp the battery sheet 3. Specifically, the battery sheet 3 is placed above the strip making assembly 20. When the pressing plate assembly 31 crimps the battery sheet 3, the strip film 2 can be tightly attached to the battery sheet 3, and the solder strip 1 can be embedded in the solder strip groove 211. The support platform 11 is provided in a rectangular shape, which facilitates the forward movement and discharging of the battery sheet 3 after the adhesive film bonding of the battery sheet 3 and the solder strip 1, avoids affecting the adhesive film bonding of the battery sheet 3 behind, forms a coherent rhythm of adhesive film bonding, and improves the processing efficiency. By providing the solder strip groove 211, when the strip film 2 is crimped, the solder strip 1 can be embedded in the solder strip groove 211, which not only can reduce the acting force between the solder strip 1 and the battery sheet 3 to reduce the risk of crushing the battery sheet 3, but also can tightly attach the strip film 2 to the surface of the battery sheet 3 to reduce the gap between the strip film 2 and the battery sheet 3, thereby improving the quality of the battery string processing.

[0037] Further, referring to Figure 2 , the support assembly 10 further comprises a plurality of adsorption plates 12 which are fixedly connected to the support platform 11 along the first direction. The surface of the adsorption plate 12 is provided with an adsorption port 121 which is connected to a negative pressure device. The adsorption port 121 can adsorb and fix the strip making plate 21. Specifically, the adsorption plate 12 is provided with a first cavity inside. The adsorption port 121 is located at the center of the first cavity and is in communication with the first cavity. The first cavity is in communication with the negative pressure device. The strip making plate 21 is adsorbed and fixed to the adsorption plate 12 through the adsorption port 121. In other embodiments, a magnetic adsorption plate can be arranged on the surface of the support platform 11, and a magnetic element can be arranged at the bottom of the strip making plate 21 to magnetically adsorb and fix the strip making plate 21.

[0038] Further, referring toFigure 2 The support assembly 10 further comprises a sealing member 13, which is arranged around the periphery of the adsorption plate 12 to seal the gap between the adsorption plate 12 and the strip making plate 21, thereby improving the quality of adsorbing and fixing the strip making plate 21. In the embodiment, a sealing groove is arranged around the periphery of the adsorption plate 12, and a corresponding clamping block is arranged at the bottom of the strip making plate 21. The clamping block is tightly clamped with the sealing groove, and the clamping surface is used to seal the gap between the adsorption plate 12 and the strip making plate 21. In other embodiments, a sealing rubber strip can be used instead of the clamping block. Since the sealing structure is a mature technology in the prior art, it will not be listed one by one here.

[0039] Further, the welding strip groove 211 is provided with adsorption holes 212, which are communicated with the adsorption port 121. The adsorption holes 212 are multiple and arranged at intervals along the first direction to adsorb and position the welding strip 1. Specifically, the inside of the strip making plate 21 is provided with a second cavity, which is communicated with the adsorption port 121 and the adsorption holes 212. The position of the welding strip 1 is positioned through the adsorption holes 212, so as to avoid the position deviation of the welding strip 1 caused by the crimping, which makes the welding strip 1 unable to be embedded into the welding strip groove 211, thereby increasing the probability of damaging the battery piece 3.

[0040] Further, the strip making assembly 20 further comprises a rubber stick 22, and the surface of the strip making plate 21 is provided with multiple glue grooves 213. The glue grooves 213 extend along the first direction and are located on both sides of each welding strip groove 211. The distance between the two glue grooves 213 is equal to the width of the strip film 2. The rubber stick 22 is embedded in the glue groove 213, and the thickness of the rubber stick 22 is greater than the depth of the glue groove 213. The rubber stick 22 is used to abut against the strip film 2 in the direction close to the battery piece 3. Since the thickness of the rubber stick 22 is greater than the depth of the glue groove 213, the rubber stick 22 will counter-press the strip film 2 when the battery piece 3 is crimped, and the stress of the strip film 2 will increase, which can effectively reduce the gap between the strip film 2 and the battery piece 3. Specifically, the glue grooves 213 arranged on both sides of each glue groove 213 form a glue groove group, and the width of each glue groove group is the same as the width of the strip film 2, so as to counter-press the two side edges of the strip film 2 and improve the crimping effect on the strip film 2.

[0041] Further, referring to Figure 4 The pressing plate assembly 31 comprises a hard plate 311 and an elastic layer 312, and the elastic layer 312 is arranged on the side of the hard plate 311 close to the strip making plate 21. Since the elastic layer 312 directly contacts the battery piece 3, it is made of flexible material such as silicone rubber, which can effectively avoid the damage to the battery piece 3 caused by the hard contact with the battery piece 3. Specifically, the elastic layer 312 is integrally formed with a crimping block 313 on the surface. The crimping block 313 extends along the first direction and is arranged at intervals along the second direction. The crimping block 313 corresponds to the rubber stick 22 one by one. The crimping block 313 and the rubber stick 22 simultaneously press the side edges of the strip film 2 on both sides. The stress of the strip film 2 on both sides will increase, which can effectively reduce the gap between the strip film 2 and the battery piece 3.

[0042] Further, the crimping mechanism 30 further comprises a lifting driving assembly 32, the lifting driving assembly 32 comprises a connecting plate 321 and an elastic piece 322, one end of the elastic piece 322 is in abutment with the connecting plate 321, the other end is in abutment with the pressing plate assembly 31, the connecting plate 321 lifting can drive the elastic piece 322 to stretch and contract, thereby driving the pressing plate assembly 31 to lift. The elastic piece 322 can buffer the pressure of the pressing plate assembly 31 directly acting on the battery piece 3, and reduce the probability of the battery piece 3 being crushed. Specifically, the connecting plate 321 is two, one of the connecting plates 321 is arranged on the side of the hard plate 311 away from the elastic layer 312, so as to avoid the elastic piece 322 damaging the hard plate 311. In the embodiment, the elastic piece 322 is arranged as a spring. In other embodiments, the elastic piece 322 can be arranged as a glued column or a glued ball, etc.

[0043] Further, the lifting driving assembly 32 further comprises a guide rod 323, the connecting plate 321 is provided with a guide hole, the guide rod 323 is in sliding fit with the guide hole, and the elastic piece 322 is sleeved outside the guide rod 323.
