Spraying operation has high production efficiency, is suitable for manual operation and industrial automation production, and has a wide range of applications, mainly in the fields of hardware, plastics, furniture, military industry, ships and so on. It is the most widely used painting method at present. Spraying operation needs a clean workshop, and the environmental requirements range from one million to one hundred. Spraying equipment includes spray gun, spray booth, paint supply room, curing oven/drying oven, spraying workpiece conveying equipment, defogging and waste water and waste gas treatment equipment.
The main problems in spraying are highly dispersed paint mist and volatile solvents, which not only pollute the environment, but also waste paint and cause economic losses. Therefore, spraying robots came into being. The environment of traditional spraying workshop is harsh, and volatile organic compounds and dust in paint seriously affect workers' health. Manual spraying is getting into trouble gradually, and it is an inevitable trend for robot spraying to replace manual spraying.
The extensive use of spraying robots has greatly liberated the labor working in dangerous environment, greatly improved the production efficiency of automobile manufacturing enterprises, brought stable spraying quality, reduced the repair rate of finished products, improved the utilization rate of paint, and reduced the discharge of waste paint and solvents.
With the continuous development and improvement of spraying technology, the reform of spraying machine technology has been going on, the requirements of automatic industrial production are gradually improving, and the principles of safe production and environmental protection production are constantly being implemented, so the emergence of spraying robots is inevitable, and this high-tech spraying equipment can also meet these requirements of various workpieces.
Painting robot is mainly composed of robot body, computer and corresponding control system. It mostly adopts articulated structure with 5 or 6 degrees of freedom. Its arm has a large movement space and can do complex trajectory movements. Its wrist generally has 2 ~ 3 degrees of freedom and can move flexibly. The wrist of a more advanced painting robot adopts a flexible wrist, which can bend and rotate in all directions. Its function is similar to a person's wrist, and it can easily penetrate into the workpiece through a small hole and spray its inner surface. Spray painting robot is generally driven by hydraulic pressure, which has the characteristics of fast action speed and good explosion-proof performance. You can teach by hand or by pointing. Spray painting robots are widely used in automobile, instrument, electrical appliance, enamel and other process production departments.
Advantages of spraying robot over manual spraying;
First, good flexibility.
(1) has large movement radius and good flexibility.
(2) Both the inner surface and the outer surface can be sprayed.
(3) It can realize the mixed production of cars, station wagons, pickup trucks and other vehicles.
Second, improve the spraying quality and material utilization rate.
(1) The profiling spraying trajectory is accurate, and the appearance spraying quality such as the uniformity of the coating film is improved.
(2) Reduce the amount of excessive spraying and cleaning solvent, and improve the material utilization rate.
Third, it is easy to operate and maintain.
(1) can be programmed off-line, which greatly shortens the field debugging time.
(2) The plug-in structure and modular design can realize the rapid installation and replacement of components and greatly shorten the maintenance time.
(3) All components can be maintained, which is convenient for maintenance.
Fourth, the equipment utilization rate is high.
(1) The utilization rate of reciprocating automatic sprayer is generally only 40%-60%, and the utilization rate of spraying robot can reach 90%-95%.
The quality of spraying robot is better than manual spraying, and the spraying robot follows the trajectory accurately without deviation, and controls the start of spray gun perfectly. Ensure that the specified coating thickness and deviation are controlled to a minimum.
The initial purchase cost of spraying robot is relatively high, but in the long run, using spraying robot is more cost-effective than manual spraying. Using spraying robot can replace expensive manual labor, reduce product cost, improve work efficiency and product quality. Here, Bian Xiao, the Erbidi spraying robot, introduces the advantages of robot spraying compared with manual spraying in detail.
Compared with ordinary manual spraying, the spraying robot can save paint and spraying agent, reduce the waste of spraying and spraying agent, prolong the life of the filter, reduce the putty content in the spraying room, significantly extend the working time of the filter and reduce the scaling in the spraying room. The transportation level is improved by 30%!
Using robots for spraying can have better process control. High-quality robot control software enables users to control all spraying parameters, such as electrostatic charge, atomization area, fan width and product pressure.
The use of spraying robots is more flexible, and products with complex geometric structures or different sizes and colors can be sprayed. In addition, a simple programming system allows automatic operation of small batch workpiece production. After the initial production, the spraying robot production line can be updated at any time.
The obvious advantages of spraying with spraying robot are to improve production efficiency, reduce defective rate and manual painting, reduce over-range spraying, and modify spraying parameters without grinding and polishing and stopping production line. Moreover, the robot has high reliability, the mean time between failure is very long, and it can work continuously in multiple shifts every day.
