This utility model discloses a high-efficiency drying device for bonding alloy wire processing, applied in the field of microelectronics technology. This utility model achieves constant tension automatic winding of the gold wire during the drying process. Its mechanical structure design effectively avoids the overlapping and uneven tension phenomena that occur during traditional winding, ensuring consistent winding density. Simultaneously, it reduces manual intervention, significantly improving production efficiency and product yield, ensuring that each gold wire achieves a uniform drying effect and a smooth winding state. An array of uniform air outlets is set at the top of the winding mechanism, realizing the synergy between dynamic drying and winding processes. Hot air evenly covers the moving gold wire, effectively solving the problem of uneven drying caused by the fixed position of traditional equipment. The synchronous drying design avoids the waste of secondary heat treatment processes.

This invention discloses a stamping and bending device for bonding alloy nameplates and plastic parts, comprising a machine base, on which a lower mold body is mounted via a support plate. A cylinder is also mounted on the machine base via a gantry frame, and an upper mold body is mounted on the lower end of the cylinder's output shaft via a hanging plate. A positioning frame is provided inside the lower mold body, within which a plastic part body, a fabric cover body, and an alloy nameplate body are stacked sequentially from bottom to top. Multiple legs of the alloy nameplate body penetrate the fabric cover body and extend below insertion holes on the surface of the plastic part body. The inner bottom surface of the positioning frame has a nameplate stamping area corresponding to the alloy nameplate body, and a stamping groove is formed in the nameplate stamping area corresponding to each leg. This invention allows the legs to enter the stamping grooves when the upper mold body is pressed down, deforming under the pressure of the groove walls. A single stamping action can complete the bonding of multiple layers of material and the bending of the nameplate legs, greatly improving production efficiency.
