Automatic paint-repairing machine

Abstract

The invention relates to an automatic paint-repairing machine comprising a painting device, a paint-supplementing device for supplying a paint for the painting device, and a driving device for driving the painting device to advance and retreat; the painting device comprises a plurality of guide rods connected with the driving device and paint-repairing heads respectively arranged at the front ends of the guide rods; the paint-supplementing device comprises a paint tank, and the paint tank is communicated with the paint heads through paint pipes. The paint-supplementing device also comprises a valve for controlling the opening and closing of the paint tank and a telescopic rod which is controlled by the driving device and can be close to and be away from the valve; the valve comprises a cylindrical valve body and a valve core accommodated in the valve body, one end of the valve core laterally extends out of the valve body; the end part of the telescopic rod is in meshing transmission with the valve core to control the valve core to rotate relative to the valve body so as to control the opening and closing of the valve. According to the automatic paint-repairing machine, meshing transmission of the telescopic rod and the valve core of the valve is driven by an air cylinder so as to control the opening of the paint tank, the paint is instantly injected into the paint-repairing heads, and automatic paint repairing is achieved; and the automatic paint-repairing machine has the advantages of high quality, high efficiency, environmental protection and low cost, and is especially suitable for automatic paint repairing of a paint with high concentration.

Description

technical field [0001] The invention relates to mechanical processing equipment, in particular to a paint repairing device. Background technique [0002] With the improvement of automation, various automation equipment will be widely used in the mechanical assembly process, including various automatic fixtures, manipulators, etc. In the process of transferring and assembling workpieces, automatic fixtures and manipulators inevitably have some hard contacts. Such hard contacts will inevitably cause damage and wear to the paint surface of the parts. Usually, the location of such paint damage is fixed. Considering various factors such as the beauty of the product and avoiding corrosion, the damaged parts of the paint surface caused by assembly must be completely repaired at the end of the assembly process. Commonly used defective paint surface repair processes mainly include manual touch-up paint and painting process. Manual repainting is time-consuming and laborious, and th...

AI Technical Summary

Problems solved by technology

Manual repainting is time-consuming and laborious, and the quality of repainting cannot be well controlled. With the increase of labor intensity, it is easy to cause missing repairs and other phenomena, which seriously affects product quality

The traditional painting process is not suitable for thick paint, and the paint in the nozzle is easy to dry out, causing the nozzle to be blocked

At the same time, it will also affect the air quality and endanger the health of operators
