Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle lamp assembly tools, and particularly relates to a novel automatic clamping mechanism for vehicle-mounted screws. Background Technique

[0002] Today's manufacturing industry is developing rapidly, with higher requirements for product quality and production efficiency.

[0003] In the production and assembly process, the vehicle-mounted screw clamping and assembly process is usually the first process on the production line. Especially for the vehicle-mounted screw clamping and assembly on the through lamp production line, it is manually installed and assembled. Manual operation has many uncertainties and cannot ensure the consistency of the assembly state of vehicle-mounted screws. Vehicle-mounted screws are usually the detection and measurement reference points of lamps. Even a small error in the assembly position of vehicle-mounted screws will be reflected in the measured dimensions of the finished lamps, which has a great impact on the quality of the finished lamps. This continuously pushes enterprises to improve the standards and requirements for vehicle-mounted screw assembly. Summary of the Utility Model
