Silica gel sealing strip production process and production line thereof

Abstract

The invention discloses a silica gel sealing strip production process. The silica gel sealing strip production process comprises the steps that 1, in-place inspection is conducted, specifically, the appearance of a shell is inspected, oil stain pollution is avoided, and clashing, scratching and deformation are avoided; 2, cleaning is conducted, specifically, cotton cloth or tissue paper is dippedin alcohol, the position, where a sealing strip needs to be mounted, of the shell is wiped, and no dirt exists; 3, gluing is conducted, specifically, continuous gluing is conducted along the position,where the sealing strip needs to be mounted, of the shell, glue discharging is uniform, and the whole circle of foamed silica gel sealing strip is formed; 4, drying is conducted, specifically, the shell with the foamed silica gel sealing strip is integrally dried; and 5, detection is conducted, specifically, the section size and the position size of the foamed silica gel sealing strip are inspected, and that the appearance is compact and free of roughness is inspected. According to the silica gel sealing strip production process, the whole circle of foamed silica gel sealing strip is formed by directly conducting gluing on the shell, the production efficiency is improved, the material and labor cost is reduced, and the sealing quality is ensured. The invention further discloses a silica gel sealing strip production line used in the process.

Description

technical field [0001] The invention relates to the technical field of production of silica gel sealing strips, in particular to a production process of silica gel sealing strips and a production line thereof. Background technique [0002] With the increasing tension of conventional petrochemical energy and the enhancement of people's awareness of environmental protection, new energy vehicles have been developed by leaps and bounds. The battery and key circuit control components in new energy vehicles need to be placed in a moisture-proof and waterproof casing, and the sealing of the casing requires the use of sealing strips. The casing sealing strips in the prior art often use foamed silica gel strips, which are die-cut and then spliced ​​and bonded in segments along the sealing contour of the casing to form a full-circle sealing strip. The foamed silicone strip requires 50% compression and a rebound of not less than 95% after ten years. [0003] However, the processing m...

Problems solved by technology

[0003] However, the processing method of the casing sealing strip in the prior art has low production efficiency, high labor cost, and there are joints formed by splicing, and the joints are the weak points of the seal, which is likely to cause seal failure
