Description

Technical Field

[0001] The utility model relates to the technical field of lamp cap welding, and mainly relates to a lamp cap welding device for a vehicle lamp. Background Art

[0002] Headlights are one of the important parts to ensure the safe driving of motor vehicles. High-quality headlights can provide drivers with good lighting and warning signals, and are one of the key factors to ensure the safe driving of cars. The components of existing automotive lights mainly include capillary tubes, fixing rings and lamp holders. Bulb installation refers to inserting the capillary tube into the lamp holder through the fixing ring and welding it to fix it. After welding and fixing, the lamp panel is welded and fixed.

[0003] When welding the lamp holder of a car lamp, due to the small force generated during welding, when only the lower outer periphery of the lamp holder and lamp cap of the lamp body is clamped and positioned, the degree of freedom is not completely restricted. During welding, the lamp holder and lamp cap will swing slightly, affecting the welding effect.

[0004] In addition, the tilt angle of the welding assembly is adjusted by using a hinged connection at the part that holds the welding pen, then adjusting the rotation angle of the hinge of the solder pen, loosening the bolts to adjust the tilt angle, and then tightening the bolts after adjustment; after long-term use, it is easy to cause the rotation angle to change slightly. Moreover, each time the tilt angle is adjusted, the position of the solder pen tip changes significantly; then aligning the welding pen with the welding position of the lamp body requires more time to readjust.
