Description

Technical Field

[0001] The invention relates to the technical field of spraying devices, in particular to an electrostatic automatic spraying device with an angle adjustment function. Background Art

[0002] Electrostatic spraying, also known as powder coating, uses plastic powder as raw material. As countries attach importance to environmental protection, powder coatings that do not pollute water and air have developed rapidly. Electrostatic spraying is a spraying method that uses a high-voltage electrostatic field to make negatively charged paint particles move in the opposite direction of the electric field and adsorb the paint particles on the surface of the workpiece.

[0003] The plastic particles used in electrostatic spraying are relatively small. Workers who spray for a long time will inevitably inhale plastic particles, causing harm to the body. At the same time, it is difficult for workers to find the spraying angle for comprehensive spraying for complex workpieces, resulting in incomplete spraying. Moreover, due to the long-term spraying work of workers, the work intensity is too high and visual fatigue will occur. Places where the spraying effect is not obvious may be missed, and they cannot be re-sprayed in time to remedy the situation. Summary of the invention

[0004] The purpose of the present invention is to provide an electrostatic automatic spraying device with an angle adjustment function to solve the problems raised in the prior art.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] The present invention provides a technical solution for an electrostatic automatic spraying device with an angle adjustment function.

[0007] The workpieces to be sprayed are placed on the conveying device in turn, sent to the spraying area by the conveying device, and then sprayed by the spraying equipment. The height of the adjusting device is adjusted by the driving device. The movement of the adjusting device will drive the movement of the spraying device, thereby adjusting the height of the spraying device, and the workpieces can be sprayed at different heights. The position of the spraying device from the workpiece is adjusted by the adjusting device, thereby adjusting the spraying effect, so that the spraying effect of workpieces of different shapes is more uniform.

[0008] Furthermore, the conveying device includes a conveying bracket, a conveying belt, a conveying motor, a conveying roller, a conveying roller and a conveying hook.

After spraying is completed, the conveying motor starts again to send the workpiece to the next working area for the next process treatment.

[0010] Furthermore, the driving device includes a driving support frame, a driving screw, a fixed plate, a driving plate and a power motor.

[0011] The driving support frame serves as the main installation basis and is used for the installation and support of other components. By placing the fixed plates symmetrically, the position of the driving plate is limited between two symmetrical fixed plates, providing a range of up and down movement for the driving plate. The driving screw is driven to rotate by the power motor output torque, and the rotation of the driving screw drives the fixed plate to have a rotation tendency. At the same time, the fixed plate limits the rotation of the driving plate, so that the driving plate moves up and down along the driving screw. The movement of the driving plate drives the movement of the adjusting device, and the movement of the adjusting device drives the movement of the spraying equipment, thereby adjusting the working height of the spraying equipment and realizing spraying processing of workpieces at different heights.

[0012] Furthermore, the adjustment device includes an adjustment base, a support plate, a first adjustment motor, a first adjustment plate, a connecting plate, a second adjustment motor and a second adjustment plate.

At the same time, the second adjusting motor outputs a torque to drive the second adjusting plate to rotate, and the rotation of the second adjusting plate drives the spraying equipment to rotate, and the working angle of the spraying equipment is adjusted until the equipment is sent to a suitable position and the angle is adjusted. The first adjusting motor and the second adjusting motor stop outputting torque, and the spraying equipment works.

[0014] Furthermore, the spraying equipment includes a spraying body, a fixing frame, a spraying rod, a nozzle, an angle adjustment device and a detection device. The spraying body is fastened to a second adjustment plate, the spraying body is connected to the angle adjustment device, the spraying body is fastened to the fixing frame, the spraying rod is hinged to the fixing frame, the spraying rod is fastened to the nozzle, the spraying body is fastened to the detection device, and the spraying rod is connected to the angle adjustment device.

When the workpiece needs to be inspected, the workpiece is illuminated by the detection light source, and then the detection camera detects it. The light on the workpiece is transmitted to the photoresistor through the detection camera, and then the intensity of the detection light source is adjusted through the photoresistor, making it easier for the detection camera to detect the spraying condition on the workpiece. At the same time, the data is sent to the processor, which then analyzes the results and controls other components to adjust the spraying angle to achieve automatic spraying.
