Relay and assembling process thereof

Abstract

The invention relates to a relay and an assembling process thereof. The relay comprises a main frame and a shell. The main frame is equipped with electrical components, and the shell is sealed on the main frame. The middle of the bottom of the main frame is provided with a sealing hole, a dispensing hole is arranged beside the sealing hole, and the sealing hole and the dispensing hole are communicated with the inside of the main frame. The assembling process comprises the following steps: a, electrical component installation: the electrical component are installed on the main frame; b, tin immersion: pins exposed out of the bottom of the main frame are tin-immersed; c, adhesive sealing: the main frame and the shell are sealed by single-component adhesive, and the sealing hole is sealed by single-component adhesive; d, baking: the relay coated with single-component adhesive is put in a baking oven and baked; e, adhesive scraping: adhesive on the shell and the pins is scraped; and f, dispensing: adhesive is put in a needle cylinder, adhesive is dispensed in the dispensing hole by the needle cylinder, and then the adhesive is baked. The invention mainly provides a solution for the problems of low sealing efficiency and high cost in the relay sealing process, the relay production efficiency is greatly improved, the assembling process is suitable for pipelining, and the production environment is cleaner, and the phenomenon of dirty adhesive preparing and dispensing in the past is changed.

Description

technical field [0001] The invention relates to a relay production process, in particular to a relay and an assembly process thereof. Background technique [0002] The relay is an electrical control device, an electrical appliance that causes the controlled quantity to undergo a predetermined step change in the electrical output circuit when the change of the input quantity meets the specified requirements. It has an interactive relationship between the control system and the controlled system. Usually used in automatic control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current. It plays the role of automatic adjustment, safety protection, conversion circuit and so on in the circuit. [0003] In order to prevent the dust, harmful gas and moisture in the air from polluting the relay, and improve the adaptability and reliability of the relay to the harsh environment, the relay generally adopts a sealed structu...

Problems solved by technology

[0005] In addition, there is another sealing process that uses the hot riveting method to seal the sealing hole, but the hot riveting method will lead to an increase in cost, and the temperature is very high during hot riveting, which is easy to damage the relay, greatly reducing the safety factor, and even more after hot riveting. The remaining hot riveting head is very ugly, affecting the appearance of the entire relay
