HUB PAINT SPRAYING TRACELESS TRANSFER METHOD AND EQUIPMENT

Abstract

Disclosed are a hub paint spraying traceless transfer method and equipment Aiming at the problem of paint film damage in the existing wet-film paint sprayed hub transfer process, the transfer method and equipment are used for transferring a wet-film hub between a spraying ground chain and an oven ground chain, and a clamping jaw of a robot clamps a tray in the transfer process to complete transfer of the wet-film hub, so that damage of the paint surface due to direct contact is avoided and the overall quality of the hub product is improved.

Claims
