Description

Technical Field

[0001] The utility model relates to a coating leakage prevention hoisting mechanism for coating processing of new energy vehicles. Background Art

[0002] New energy vehicle painting is a key link in the manufacturing process of new energy vehicles. It involves applying paint and other protective layers to the surface of the vehicle to protect the body, prevent corrosion, and improve appearance and identification. New energy vehicle painting includes pretreatment to ensure the adhesion of the coating, and then forming a uniform layer of primer on the body through electrophoresis, followed by mid-coating and top-coating, drying and curing, and testing. During the painting process, parts other than the body usually need to be hoisted to a dedicated painting workshop using a hoisting mechanism, and all-round painting is performed using rotary spraying to ensure full coverage of the coating.

[0003] However, most of the current lifting mechanisms need to contact the parts to ensure that they are lifted, and in order to ensure a stable coating process, the lifting mechanisms usually need to firmly fix the parts. This results in the contact position between the lifting fixture and the parts not being affected by the spraying device, resulting in the inability of the fixed points to cover the paint surface. The staff can only wait for other paint surfaces to dry and solidify before changing the fixed points and spraying the previous fixed points, resulting in reduced coating efficiency. In addition, changing the fixed points may damage the already solidified paint surface, affecting the coating quality and increasing the number of rework times. Utility Model Content
