Description

Technical Field

[0002] With the widespread application of automated adhesive coating technology in automobile manufacturing and new energy battery fields, the coating method, process, and efficiency directly affect the manufacturing cycle and quality of products. Traditional manual or semi-automatic adhesive coating equipment suffers from low efficiency, poor consistency, and adhesive waste, making it difficult to meet the demands of high-precision, high-volume production. Especially in scenarios such as automotive body sealing and power battery pack packaging, continuous, uniform, and high-precision adhesive spraying is required. Existing adhesive spraying systems mostly adopt single-valve intermittent operation and manual application. During high-speed continuous coating, the valve body needs to be frequently started and stopped, which not only reduces production efficiency but also makes the adhesive stability susceptible to fluctuations in adhesive line pressure. In particular, changing the adhesive canister requires a long downtime.
