Vehicle automatic intelligent spraying system

Abstract

The invention discloses a vehicle automatic intelligent spraying system. The vehicle automatic intelligent spraying system comprises one or more cantilever type five-axis linkage spraying structures;each cantilever type five-axis linkage spraying structure comprises at least an X-axis assembling body, a Y-axis assembling body, a Z-axis assembling body, a first rotary shaft and a second rotary shaft; a spraying assembly is arranged on one side of any rotary shaft; and the spraying assembly can be driven through five-axis linkage to achieve reciprocating motion and spraying in the any designated direction in the space. According to the vehicle automatic intelligent spraying system, through configuration and combination of the two cantilever type five-axis linkage spraying structures, left-right double station spraying can be achieved, and accordingly, the spraying efficiency of a whole vehicle is improved; the spraying frequency and amplitude of a spray head can be automatically adjusted according to the motion speed of the spraying system, accordingly, uniformity of the spraying thickness and the definition of the edge of a sprayed pattern are ensured, and automatic precise spraying of a multi-color pattern, unshaded and free of over spraying, on the whole vehicle body is indirectly achieved.

Description

technical field [0001] The invention belongs to the field of automatic spraying equipment, and in particular relates to a double-column cantilever type five-axis linkage spraying system, which also includes a precision spraying head with controllable spraying volume and spraying frequency. Background technique [0002] The spraying of multi-color patterns on the vehicle body is an indispensable link in the field of automobile painting. In the prior art, the multi-color pattern spraying of vehicles is still mainly done manually, and the partial monochrome spraying is carried out with a mechanical arm structure. However, due to mechanical The arm structure is mainly based on rotary motion, with slow running speed, low precision, poor load-bearing, complex motion trajectory planning, and expensive, so it is rarely used in the actual spraying of vehicles. [0003] Existing vehicle body spraying uses a spray gun with a simple driving method, mainly pneumatic, switch control, and ...

[0002] The spraying of multi-color patterns on the vehicle body is an indispensable link in the field of automobile painting. In the prior art, the multi-color pattern spraying of vehicles is still mainly done manually, and the partial monochrome spraying is carried out by a mechanical arm structure. However, due to mechanical The arm structure is mainly based on rotary motion, with slow running speed, low precision, poor load-bearing, complex motion trajectory planning, and expensive, so it is rarely used in the actual spraying of vehicles

[0003] Existing vehicle body spraying uses a spray gun with a simple driving method, mainly pneumatic, switch control, and difficult to control the spraying amount. Generally, it sprays out cone-shaped mist paint, and the spraying point is circular, with a diameter of 200-400mm. The spray distance is generally about 300-500mm, which is easy to cause overspray, serious loss during the spraying process, about 30% of the paint splash loss, and easy to cause serious pollution in the working space. Operators must wear a full set of protective clothing to minimize health damage

When spraying multi-color pattern color separation, you must manually cover the masking tape to avoid the area where this color is not sprayed. After spraying, you must wait for the color to dry, then remove the tape, and then spray the second color, and repeat. , the spraying efficiency is low, and it is difficult to realize automatic intelligent spraying without masking and overspray
