Intelligent automatic spraying unit based on digital bus and usage method thereof

Abstract

The invention discloses an intelligent automatic spraying unit based on a digital bus and a usage method thereof. The intelligent automatic spraying unit comprises a mechanical arm (1), a spraying device (2), a control valve bank (3) and an electric control device (4). The spraying device comprises a body (21) and a spraying head (23). The interior of the body is at least provided with two inner channels (211). Outer channels (212) which are identical to the inner channels in number and are communicated with the inner channels respectively are arranged outside the body. The body is further provided with a pattern recognition sensor, a position sensor and a range sensor. Spraying orifices (231) communicated with the inner channels are formed in the positions, corresponding to the inner channels, of the interior of the spraying head. The control valve bank comprises a positive-pressure control solenoid valve, a paint control solenoid valve and a negative-pressure control solenoid valve which are connected with the inner channels and the outer channels through pipelines. The electric control device comprises a pattern recognition circuit, a spraying parameter analyzing and planning circuit and the like. The spraying unit can enhance the recovery rate of paint waste gas and achieve intelligent spraying, thereby being suitable for digital bus factories.

Description

technical field [0001] The invention relates to an automatic spraying unit and a using method thereof, in particular to an intelligent automatic spraying unit based on a digital bus suitable for a digital bus factory spraying process and a using method thereof, and belongs to the technical equipment field of painting equipment. Background technique [0002] With the development of society and the improvement of people's living standards, the market has put forward higher and higher requirements for the surface treatment of industrial products and daily products. Mist spraying on the surface of the object to be coated, the coating forms a solid film with strong adhesion and a certain strength, which can prevent the external environment from damaging the surface of the product and prolong the service life. At the same time, it can obtain a colorful appearance and beautify the environment. Different coatings provide special functions such as anti-mildew, sterilization, high tem...

AI Technical Summary

Problems solved by technology

[0005] 1. The mist paint sprayed by the spraying unit during the spraying process cannot be completely sprayed on the surface of the workpiece or product. The mist paint diffused in the spraying room or in the spraying room will adhere to the walls and equipment. Simply by setting it in the spraying room Or the exhaust unit in the spraying room is used to recover and discharge the paint exhaust gas. The recovery rate of the paint exhaust gas is not high. The paint adhered to the walls and equipment cannot be recycled, the waste is serious, and it is difficult to clean up;

[0006] 2. Since the waste gas is recovered and discharged simply through the exhaust unit installed in the spraying room or the spraying room, the air pollution in the spraying room or the spraying room is serious. If the equipment fails or other circumstances require personnel to enter, it needs to be exhausted. Personnel can enter the unit only after it has been discharged for a certain period of time, resulting in a waste of time and a decrease in efficiency;

[0007] 3. The spraying units are mostly controlled by industrial control computers. The data such as spraying path and spraying speed depend on the setting of the program, and intelligent spraying cannot be realized. Therefore, each workpiece or product must be programmed before spraying. For spraying, the operation is more complicated and the degree of automation is not high
