Description

Technical Field

[0001] The present invention relates to the technical field of coil processing, in particular to a coil wire stripping and welding machine. Background Art

[0002] After the coil is wound and formed, the periphery of the coil that needs to be welded needs to be stripped and then welded to the sheet. In the past, a stripping tool was used for wire stripping. However, due to the ductility of the outer skin, there will be a certain amount of rebound after stripping, resulting in inaccurate wire stripping position accuracy. When welding with the sheet later, it is easy to contact the outer skin, resulting in defective products. For this reason, a laser machine is currently used for wire stripping. Using a laser machine for wire stripping can improve the position accuracy of wire stripping. However, in the existing laser wire stripping equipment, after the coil is installed and fixed, the coil can only be stripped from the upper and lower sides, and the left and right sides cannot be stripped. As a result, poor welding is prone to occur during the welding process, so it still needs to be improved. Summary of the Invention

The separated product material belt is sent to the right to the next processing equipment, and the carrier continues to circulate and transport, and picks up the next group of coils for a new round of processing. This design can complete the coil stripping and welding processes with high precision and efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
