Automatic assembly process for production and manufacturing of molded case circuit breaker

Abstract

The invention relates to an automatic assembly process for a production and manufacturing of amolded case circuit breaker. The automatic assembly process for production and manufacturing of the moldedcase circuit breaker adopts molded case circuit breaker production and manufacturing automatic assembly equipment, and the molded case circuit breaker production and manufacturing automatic assemblyequipment comprises a mounting seat, a fixing device and a combination device; and the lower end of the mounting seat is arranged on the ground, the fixing devices are connected with the left and right sides of the mounting seat, the combination device is arranged above the fixing devices, and the lower end of the combination device is connected with the upper end of the mounting seat. Before thecircuit breaker is assembled through the combination device, the corresponding positions of the upper portion and the lower portion of a circuit breaker can be detected and adjusted, and the situationthat the upper portion and the lower portion of the circuit breaker are not aligned up and down, and deviation occurs is prevented; and the clamp of each fixing device is composed of the left part and the right part, and circuit breakers with different lengths can be aligned and assembled, so the assembling cost is saved.

Description

technical field [0001] The invention relates to the technical field of molded case circuit breakers, in particular to an automatic assembly process for the production and manufacture of molded case circuit breakers. Background technique [0002] The molded case circuit breaker can automatically cut off the current after the current exceeds the trip setting. The plastic case refers to the use of plastic insulators as the outer casing of the device to isolate conductors and grounded metal parts. Molded case circuit breakers usually contain thermal magnets. Trip unit, while the large model molded case circuit breaker will be equipped with a solid-state trip sensor, and its trip unit is divided into thermal magnetic trip and electronic trip unit. [0003] The shell of the molded case circuit breaker is divided into an upper shell and a lower shell. After the internal parts of the molded case circuit breaker are installed, the upper shell and the lower shell need to be fixed and ...

AI Technical Summary

Problems solved by technology

[0004] (1) Before assembling the upper shell and the lower shell, it is necessary to align the positions of the upper shell and the lower shell up and down. During the alignment process, there may be small deviations that are not easy to see. When fixing with screws, due to The fixing holes are not completely aligned up and down, which makes it difficult for the screws to be screwed in or the screws expand the fixing holes;

[0005] (2) The circuit breaker has many different sizes, and the upper case and the lower case of the circuit breaker of different sizes are aligned and assembled, so the manufacturer needs to purchase the corresponding fixing device to fix it, thereby increasing the assembly cost
