As shown in fig. 1 and 2, the tape 100 includes: a plurality of metal sheets 200 to be assembled, and a remnant 300 connecting the metal sheets 200 to be assembled.
A first positioning hole 1001 is formed in the excess material 300 between each metal material sheet 200 to be assembled and the edge of the material strip, and the first positioning hole 1001 can position the material strip 100 during feeding and stamping.
Before assembling the metal sheet 200 to be assembled on the motor module, the metal sheet 200 to be assembled needs to be subjected to feeding and stamping processing, and the memory alloy wires are hung on the metal sheet 200 to be assembled through a wire clamp.
When the memory alloy wire is hung, the wire pliers are positioned on two sides of the metal sheet 200 to be assembled, and the metal sheet 200 to be assembled needs to be positioned in the process.
As shown in fig. 2, if the first positioning hole 1001 shown in fig. 1 is directly used to position the metal sheet 200 to be assembled, the wire clamp needs to avoid the first positioning hole 1001, increasing the distance L between the clamping jaw and the wire clamp, and after wire hanging is finished, the memory alloy wires between the wire clamp and the first steel sheet 101, the second steel sheet 102 and the third steel sheet 201 need to be cut off, which causes waste of the memory alloy wires and increases production cost.
