Figures 1 to 24 An embodiment of the battery current collector production equipment includes a bearing frame 300, an unwinding device 400, a metal net processing device 200, a feeding device 500 and a winding device 100, the unwinding device 400 is arranged on the bearing frame 300 and is used to unwind the coiled material 20, the metal net processing device 200 is arranged on the bearing frame 300 and is used to process the coiled material 20 into a metal net, the feeding device 500 is arranged on the bearing frame 300 and is located between the unwinding device 400 and the metal net processing device 200, so that the coiled material 20 can be transported to the metal net processing device 200, and the winding device 100 is arranged on the bearing frame 300 and is used to wind the metal net.

[0070] In the embodiment, the metal net processing device 200 includes a first cutter 220 and a second cutter 230, the first cutting edge 221 of the first cutter 220 is flat, the second cutting edge 231 of the second cutter 230 is tooth-shaped, the first cutter 220 and the second cutter 230 enclose a cutting space and can approach and move away from each other, so as to process the coiled material 20 in the cutting space into a metal net.

[0071] It is understandable that, since the first cutting edge 221 of the first cutter 220 in the metal mesh processing device 200 is a flat blade and the second cutting edge 231 of the second cutter 230 is toothed, and the first cutter 220 and the second cutter 230 enclose a cutting space and can approach and move away from each other, the roll material 20 in the cutting space is processed into a metal mesh.

[0072] In one embodiment, please refer to Figures 8 to 15 The metal mesh processing device 200 includes a frame 210 and a drive mechanism 250. The frame 210 is mounted on the support frame 300. The drive mechanism 250 is mounted on the frame 210 and is used to drive one of the first cutter 220 and the second cutter 230 to move relative to the other. The first cutter 220 can move closer to or away from the second cutter 230 along a straight line in a first direction, and the first cutter 220 can also reciprocate along a straight line in a second direction relative to the second cutter 230 to process the roll material 20 in the cutting space into a metal mesh. The first direction and the second direction are set at an angle. By setting the staggered movement of the first cutter 220 and the second cutter 230, the material utilization rate of the roll material 20 can be improved, while reducing the mesh size and wire diameter, thereby improving the forming quality of the metal mesh.

[0073] In one embodiment, the drive mechanism 250 includes a first drive assembly 251 and a second drive assembly 252. The first drive assembly 251 is mounted on the frame 210 and connected to the second drive assembly 252. The second drive assembly 252 is connected to the second cutter 230. One of the first drive assembly 251 and the second drive assembly 252 drives the second cutter 230 to reciprocate along a straight line in a first direction, and the other drives the second cutter 230 to reciprocate along a straight line in a second direction, thereby realizing the offset movement of the first cutter 220 and the second cutter 230.

Specifically, both the first drive assembly 251 and the second drive assembly 252 are linear motors.

[0074] In an embodiment, the metal mesh processing device 200 further comprises an adaptive structure 260; the first cutter 220 is formed with a first matching surface 222 on one side relative to the second cutter 230, and the second cutter 230 is formed with a second matching surface 232 on one side relative to the first cutter 220, the first matching surface 222 and the second matching surface 232 guide and match, and are used to guide the second blade edge 231 of the second cutter 230 and the first blade edge 221 of the first cutter 220 to move in alignment, so as to ensure the alignment accuracy and facilitate to improve the material utilization rate of the coiled material 20.
