[0002] Electrostatic spraying is a new type of painting method designed by using the basic characteristics that like charges repel each other and unlike charges attract each other. It uses the effect of a DC high-voltage electric field to make the paint mist sprayed from the spray gun finer and charge the paint mist. Through electrostatic attraction, it is deposited on the surface of the workpiece with different charges to form a uniform paint film, achieving the purpose of painting. It is an efficient painting method that combines mechanical atomization with electrostatic attraction and repulsion.

The hydraulic push rod 19 is extended and retracted to drive the mounting column 15 to move up and down inside the spraying cabinet 4, thereby ensuring that the four sides of the workpiece are sprayed comprehensively, and the paint spray gun 16 is always located inside the spraying cabinet 4 to ensure that it will not be sprayed to the outside, thereby avoiding excess spray liquid from dripping onto the ground and causing environmental pollution.

[0026] Preferably, the rotary spraying assembly 5 also includes a mounting column 15 and a rotating rod 17, the rotating rod 17 is keyed to the output end of the servo motor 18, two groups of mounting columns 15 are provided, and the two groups of mounting columns 15 are respectively connected to the two ends of the rotating rod 17, and several groups of paint spray guns 16 are provided, and several groups of paint spray guns 16 are through-set on the corresponding surfaces of the two groups of mounting columns 15. The servo motor 18 drives the rotating rod 17 to repeatedly rotate 180 degrees, thereby driving the two groups of mounting columns 15 to repeatedly rotate 180 degrees inside the spray cabinet 4, and then the workpiece inside the spray cabinet 4 is sprayed on all sides by several groups of paint spray guns 16, thereby improving the spraying efficiency of electrostatic spraying.

[0027] Furthermore, two groups of paint storage boxes 7 are arranged on the upper surface of the base plate 1, and the upper surfaces of the two groups of paint storage boxes 7 are sealed with delivery hoses 8, and the two groups of delivery hoses 8 are respectively sealed and connected to the two groups of mounting columns 15. A plurality of support rods 6 are fixedly arranged on the upper surface of the base plate 1, and the spray cabinet 4 is arranged on the upper surface of the base plate 1 through a plurality of support rods 6. The two groups of paint storage boxes 7 are sealed and connected to the mounting columns 15 through the two groups of delivery hoses 8, thereby providing spray liquid to the paint spray gun 16, and the delivery hose 8 is arranged as a hose. When the mounting column 15 rotates, the delivery hose 8 will rotate with it, and the mounting column 15 only rotates repeatedly 180 degrees, so the delivery hose 8 will not be entangled.

When the sliding block 12 moves, the vacuum suction cup 13 is driven to move, and the workpiece is adsorbed by the vacuum suction cup 13 and sent into the spray cabinet 4. The moving groove 14 is opened to ensure that the vacuum suction cup 13 can enter and exit the spray cabinet 4 unloaded.

[0031] In addition, compression springs 23 are fixedly connected to the bottom ends of the corresponding surfaces of the two groups of cabinet doors 2, and installation grooves 22 corresponding to the compression springs 23 are opened at the bottom ends of the two groups of cabinet doors 2. Two groups of limiting columns 24 are arranged on the corresponding surfaces of the two groups of cabinet doors 2, and the two ends of the compression springs 23 are respectively sleeved on the outer arc surfaces of the two groups of limiting columns 24. When the vacuum suction cup 13 adsorbs the workpiece close to the cabinet door 2, the workpiece squeezes the cabinet door 2, and the cabinet door 2 rotates to release the workpiece into the spray cabinet 4. After the workpiece enters the spray cabinet 4, the cabinet door 2 returns to its original state under the action of the compression spring 23, and the limiting column 24 is arranged to ensure that the compression spring 23 is limited to avoid excessive bending and breakage of the compression spring 23.
