Automatic and uniform painting device and method for laser transmission welding absorption layer

Abstract

The invention provides an automatic and uniform painting device and method for a laser transmission welding absorption layer. The device comprises a painting system, a drying system, a discharging system and a control system, wherein the painting system comprises a working platform, double starting buttons, a support plate, limiting blocks, screw motors, motor mounting plates, support imitation blocks and a painting device; the drying system comprises infrared lamps, flexible tubes and support seats; the discharging system comprises air cylinders, a beveled guide groove and a material collecting box; and the control system comprises a computer, an X-axis module, a Y-axis module, a Z-axis module, a dispensing machine and a switching power supply. The automatic and uniform painting device and method for the laser transmission welding absorption layer have the benefits as follows: the flow rate of dispensing valves is adjusted by utilizing the dispensing machine, the flow rate of a blackpaint is controlled in the painting process of needle brushes, both the thickness and uniformly of the black paint are controlled by adopting a multiple painting method, the black paint is quickly dried by utilizing the infrared lamps, the automatic discharging of plastic plates is realized by utilizing the air cylinders, any two pieces of plastic plates can be painted simultaneously through the device, and the efficiency is greatly increased.

Description

technical field [0001] The invention belongs to the field of laser transmission welding, in particular to an automatic and uniform painting device and method for absorbing layers on the surface of thermoplastic plates. Background technique [0002] Thermoplastic polymers and their composite materials have the advantages of light weight of finished products, excellent physical properties, low cost, energy saving and earthquake resistance, etc., and their applications in industry are becoming more and more extensive. In actual industrial applications, due to injection molding, extrusion processing and other reasons, many plastic products with complex shapes and structures cannot be formed at one time, and need to be connected. Compared with some traditional polymer connection methods, laser transmission connection has become the most potential new connection method between thermoplastic polymers due to its advantages of high efficiency, reliability, fastness and beauty, and is...

AI Technical Summary

Problems solved by technology

For artificial painting, not only is the efficiency low, but also has a certain impact on human health, and the thickness and uniformity of the spray paint cannot be guaranteed.

For machine painting, the quality of the painting cannot be accurately guaranteed, and there is also a lack of automatic drying equipment
