Servo cleaning device and method for automotive body painting production line

Abstract

The invention provides a servo cleaning device and method for an automotive body painting production line. Servo spray washing is carried out on an automotive body after the phosphating treatment, thereby greatly reducing residual phosphating liquid on the upper surface of the automotive body. Furthermore, during the process when the phosphating liquid is transferred from a phosphating slot to a washing tank, the probability of excessive reaction happening between the residual phosphating liquid and the automotive body can be reduced, thereby improving the once qualified rate of products and reducing the reworking and repairing cost of the automotive body. The servo cleaning device for the automotive body painting production line has the advantages of being adapt to car models of different height and achievable in automatically setting the height of nozzles, thereby making the automotive body sprayed more uniformly. Maintaining a reasonable distance, water can be saved while the residual phosphating liquid can be removed. Blowing is carried out on the automotive body after being sprayed, and drops of water on the surface of the automotive body can be removed, thereby preventing the residue of the phosphating liquid. The automotive body can move back and forth along with a horizontal transmission mechanism, thereby ensuring the uniformity of the spraying and blowing operation. Forward, backward and forward again, the spraying and blowing operation should be completed two times and there are no extra steps, thereby reducing the process cost.

Description

technical field [0001] The invention relates to the technical field of car body painting, in particular to a follow-up cleaning device and method for a car body painting production line. Background technique [0002] Almost all modern automobile production lines use water-based cathodic electrophoretic primers with high environmental protection and high coating rate for the anti-corrosion primer coating of car bodies. Fully automated management. The existing automobile body painting production line includes two parts: pre-treatment technology and coating construction process. The main method is full immersion. After pre-treatment and phosphating, the car body enters electrophoretic coating through water washing. In the specific production process, we found that the existing body painting line has shortcomings. Because the cleaning and spraying devices are mostly fixed on both sides, and the shape of the body is uneven, and with the movement of the transmission mechanism, th...

Problems solved by technology

In the specific production process, we found that the existing body painting line has shortcomings. Because the cleaning and spraying devices are mostly fixed on both sides, and the shape of the body is uneven, and with the movement of the transmission mechanism, the cleaning of the upper surface of the body is uneven. , Incomplete phenomena occur from time to time. During the period from leaving the phosphating tank to entering the washing tank, the phosphating solution remaining on the upper surface of the car body still reacts with the car body, which affects the overall phosphating effect of the car body and makes the electrophoresis quality Uneven, rework and rework costs increase
