[0022] During implementation, the resistor is fed through the resistor feeding assembly 1. During feeding, the resistor is straightened by the chain straightening assembly 11. After straightening, the resistor is transported to the cylinder bending assembly 13 station by the PUU robot 2. The cylinder in the cylinder bending assembly 13 drives the bending head to bend the resistor by connecting rod. After bending, the PUU robot 2 transports the resistor to the cylinder cutting assembly 14 station. The cylinder in the cylinder cutting assembly 14 drives the cutter to cut the resistor by connecting rod.

[0024] During implementation, the resistor is gripped by the cylinder jaws 33 in the rotating moving assembly 3. After gripping, the resistor is rotated 90 degrees by the rotary motor 32, and then the linear module 31 drives the resistor to be moved to the welding head assembly 4.
[0025] Furthermore, such as Figure 3 as well as Figure 4 As shown, a welding head assembly 4 is provided on one side of the resistor feeding assembly 1.

[0027] Working principle: During use, the resistor is fed through the resistor feeding assembly 1. During feeding, the resistor is straightened by the chain straightening assembly 11. After straightening, the resistor is transported to the cylinder bending assembly 13 station by the PUU robot 2. The cylinder in the cylinder bending assembly 13 drives the bending head to bend the resistor through the connecting rod. After bending, the PUU robot 2 transports the resistor to the cylinder cutting assembly 14 station. The cylinder in the cylinder cutting assembly 14 drives the cutter to cut the resistor.
[0028] After cutting the lead, the resistor is gripped by the cylinder jaws 33 in the rotating and moving assembly 3. After gripping, it is rotated 90 degrees by the rotary motor 32. Then, the linear module 31 drives the resistor to be moved to the welding head assembly 4. Next, the movable cylinder 42 at the top of the bracket 41 drives the welding head movable assembly 43 to move down. The welding head movable assembly 43, together with the welding head fixing assembly 44, welds the resistor to the ribbon cable board, thus completing the use of the resistor welding mechanism.
