Pure mechanical drive type spray painting robot

Abstract

The invention belongs to the technical field of industrial robot application, and discloses a pure mechanical drive type spray painting robot. The pure mechanical drive type spray painting robot comprises a five degree-of-freedom robot and a positive pressure explosion protection system. The five degree-of-freedom robot comprises a fixed base, a rotary base, a rotary driving device, a tail end installation seat, a spray gun, a position adjusting rod group, a posture adjusting rod group and synchronous wheel drive. The position adjusting rod group comprises a servo motor, a big arm, a front arm, a small arm and a small arm pull rod; the posture adjusting rod group comprises an electric sliding table, an electric cylinder fixed seat, a first posture protection rod, a triangle connecting frame, a second posture protection rod and a spring supporting rod; the synchronous wheel drive comprises the servo motor, a synchronous pulley and a synchronous belt; and the positive pressure explosionprotection system comprises an air pump, an air pipe and a sealing shell. A pure mechanical drive scheme is adopted, electrical parts are placed on bottoms of robot bases and branched chains, integralexplosion protection is carried out, the production efficiency is high, the safety performance is high, and automatic spray painting operation can be realized.

Description

technical field [0001] The invention belongs to the field of industrial robots, and in particular relates to a purely mechanically driven spraying robot. Background technique [0002] Spraying robots are widely used in fields such as hardware, plastics, furniture, military industry, and ships. They are the most commonly used coating method today; during the process of spraying workpieces by spraying robots, the sprayed paint gas mainly contains stupid , toluene, xylene, formaldehyde, butadiene and gasoline and other flammable gases, if a spark occurs at the wiring port of an electrical component in the robot or the heat generated by the motor during operation makes the temperature too high, it may ignite the flammable gas in the sealed cavity. Combustible material can cause an explosion. At present, foreign companies that produce painting robot products are mainly ABB in Sweden, FANUC, YASKAWA, KAWASAKI in Japan, etc. Their painting technology is already in the application ...

AI Technical Summary

Problems solved by technology

Most plate and sheet metal products such as machine tool beds and home appliance covers only need to be sprayed on the outer surface, and the outer surface structure is relatively simple, and the requirements for the spraying accuracy of the robot are low. If the above-mentioned articulated robot with degrees of freedom is used, it will increase the production of enterprises. and upgrade costs, resulting in unnecessary waste

At present, in order to save costs, some enterprises still use reciprocating automatic spraying lines for spraying operations. There are problems such as large spraying errors, large amount of paint usage, high defect rate, uneven partial spraying, etc., which seriously affect the product appearance and spraying efficiency.
