A high-voltage electrostatic coating equipment for new energy vehicles

Abstract

The invention discloses a high-voltage electrostatic coating equipment for new energy vehicles, which includes a central controller, a voltage transformer and a voltage stabilizer, and a bottom plate. A paint tank and a discharge pump are placed on the bottom plate. The feed pump of the discharge pump The end passes through the paint tank and extends to the inside of the paint tank. The output port of the discharge pump is fixedly installed with a pipe. The top outer wall of the bottom plate is provided with a guide rail and two symmetrically distributed support columns, and the two support columns A reinforcing rod is rotatably connected between them through a bearing, and a corner rod is arranged on one side of the outer wall of the reinforcing rod, and a rotating ball is arranged at one end of the corner rod. In the present invention, the chain plate is kept in a curved shape, and then the linear motor is started, and the linear motor drives the moving block to move up and down in the process of moving up and down, so that the reinforcing rod is supported by the supporting column to rotate, thereby driving the spray gun body installed on the mounting plate to rotate , The moving trajectory of the spray gun body is arc-shaped, thereby realizing curved surface spraying. Due to the high precision of the linear motor, the spraying precision is high and the spraying effect is good.

Description

technical field [0001] The invention relates to the technical field of electrostatic spraying, in particular to a high-voltage electrostatic coating equipment for new energy vehicles. Background technique [0002] High-voltage electrostatic spraying mainly uses a corona discharge electrostatic powder spray gun system to complete powder spraying. The system mainly includes: a high-voltage electrostatic generator, which is composed of a high-frequency transformer and a boost circuit; a corona discharge electrode, which is composed of a needle electrode and a ring electrode; a spray regulator; air and powder conveying pipelines. With the continuous development and innovation of spraying technology, it is now possible to install a high-voltage electrostatic generator inside the spray gun. Turn on the low-voltage power supply, convert it into high-voltage electricity through a multi-stage booster, and apply it to the corona discharge electrode or ring electrode at the end of the...

Problems solved by technology

[0003] In order to reduce the workload of the personnel, the spray gun originally held by the personnel is fixed on the bracket, and the start and stop of the spray gun are controlled through the cooperation of the sensor and the integrated control system. When the existing device is spraying, the spray gun is fixed on the bracket and can spray straight panels. However, when spraying curved new energy vehicle parts, it is necessary to adjust the angle of the spray gun multiple times, or use multiple stations for spraying. Since the spraying is not completed at one time, when changing the spraying station or adjusting the angle of the spray gun , prone to uneven spraying, resulting in waste of materials and affecting the quality of the workpiece
