Coating gun with built-in dust collection

Abstract

This invention relates to a dust collection device for a coating gun, employing a semi-enclosed dust collection structure on the outside of the coating gun; an exhaust pipe on the semi-enclosed dust collection structure; and a sliding device on the semi-enclosed dust collection structure. During the movement of the coating gun, the exhaust pipe, within the semi-enclosed dust collection structure, performs dust collection along with the coating gun, while the sliding device slides during movement to allow the coating gun to avoid obstacles. Compared to traditional dust collection mechanisms, this device achieves a semi-enclosed cavity, resulting in better dust collection. Furthermore, the semi-enclosed dust collection structure includes a moving mechanism to avoid local protrusions in the battery box. This solves the problem in existing technologies where the complex contours of the battery box and the presence of local protrusions place high demands on the following dust collection mechanism. Traditional high-altitude or side-mounted dust collection methods are no longer suitable for plasma coating processes and cannot meet the required technical requirements.

A special protective film needs to be coated on the contact area between the aluminum profile and the sealing ring to play a corrosion protection role; when spraying the protective film of the aluminum profile, the plasma coating process is adopted. In the coating process, the excess dust needs to be removed, on the one hand to prevent the coating gun nozzle from accumulating and affecting the coating quality, and on the other hand to affect the environment. Due to the complex profile of the battery box around, there are local protrusions, so the following dust removal mechanism is required.
