Description

technical field [0001] The invention relates to an automatic assembly device for a round head dimming screw, which belongs to the technical field of motor vehicle lamp processing. Background technique [0002] Most of the headlights of motor vehicles are dimmed using flexible and convenient ball head dimming mechanisms. See Figure 7 As shown, the dimming mechanism of the motor vehicle headlamp is mostly composed of a dimming screw, a dimming nut and a nut seat. Shape, the spherical surface outside the dimming nut is installed on the spherical surface of the nut seat, the dimming screw is screwed on the dimming nut and connected with the connector inside the lamp, and the purpose of dimming is achieved by rotating the dimming screw. During the assembly process of the conventional ball head dimming mechanism, the dimming screw is usually screwed onto the dimming nut first, and then the dimming nut is pressed into the nut seat. However, because the outer circumference of the...

AI Technical Summary

Problems solved by technology

However, because the outer circumference of the dimming nut is spherical, the shaft of the dimming screw is round and both ends are flat. Since there is no cross recess and hexagonal head, it is impossible to use an electric screwdriver or wrench for installation. Manual assembly is not only labor-intensive , and the assembly efficiency is not high, and it is easy to cause damage to the thread, so that the product qualification rate is not high
