AI Technical Summary

Technical Problem

Existing automatic signal light assembly equipment cannot effectively solve problems such as the symmetrical feeding of the two contact plates, the vibration feeding jamming of the sealing ring, the difficulty of screwing in the nut ring, the difficulty of fixing the lamp head pin, and the difficulty of assembling the parts in the correct direction, resulting in low automated assembly efficiency and unstable finished product quality.

Method used

The system employs first and second rotary tables in conjunction with fixture sets, a flipping device, adsorption clamps, and a bending device to achieve automated assembly of parts. Through the coordinated work of the fixture sets, the system accurately feeds, flips, and fixes each component of the signal light, ensuring that the parts are assembled in the correct orientation. Negative pressure adsorption and elastic clamping are used to solve the problems of feeding jamming and damage.

Benefits of technology

It enables highly efficient and automated assembly of traffic lights, improves finished product quality and assembly efficiency, reduces long-term costs, is suitable for mass production, and reduces scrap rate and resource waste.

Abstract

This invention discloses an automatic signal light assembly device, belonging to the field of automation equipment technology. The first rotary table has, in rotational order, a housing loading station, a contact plate loading station, a screw loading and tightening station, a sealing ring loading station, a nut ring loading and tightening station, a flipping station, a lamp body loading station, and a semi-finished product transfer station. The second rotary table has, in rotational order, a base loading station, a semi-finished product transfer station, an inner cover loading station, an outer cover loading station, and a discharge station. The devices corresponding to each station perform corresponding loading, flipping, handling, or discharge operations. Through the cooperation of the various stations on the two rotary tables, the assembly of various parts is completed, basically realizing automated assembly of signal lights, improving assembly efficiency, consistently improving finished product quality, reducing long-term costs, and enhancing the level of automation. It is suitable for mass assembly operations and accelerates the assembly speed.
