The arm is a multi-joint structure, and the arm is connected to the base through a turntable that can rotate horizontally; the paint gun is installed at the top of the arm; the paint pipe runs along the arm to connect the paint gun and the paint bucket arranged outside the arm; the PLC is arranged in the electric control box, and the PLC is electrically connected to the arm, the electric control box, and the paint gun.

[0003] The above six-joint painting robot can spray paint on the plate at multiple angles. However, in actual use, there are still some defects. For example, after the plate is painted, the operator needs to walk to the painting area to take the painted plate from the workbench and then place the next plate. During this process, the operator will inhale a large amount of paint gas when entering the painting area, which will cause harm to the human body, and the continuity of plate painting is poor, and the efficiency needs to be improved.

[0004] Therefore, an automatic numerical control painting device is proposed. Content of the Utility Model

[0024] The following will cooperate with the drawings and embodiments to detail the implementation manners of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0025] Please refer to Figures 1 to 3 As shown, this embodiment provides an automatic numerically controlled paint spraying device, including a robot 1 and a base 4. A spray gun 101 is installed at the actuator end of the robot 1. A support column 401 is fixedly installed on the top of the base 4. In order to improve the support strength of the support column 401, a plurality of reinforcing rods 404 are fixedly connected to the support column 401. The bottom of the reinforcing rod 404 is fixedly connected to the top of the base 4. The top of the support column 401 is fixedly connected to the bottom of the robot 1 through an installation plate 402. A rotating mechanism 2 is arranged on the support column 401;

[0026] The rotating mechanism 2 includes an installation housing 201. The installation housing 201 is rotatably sleeved on the installation plate 402. In this embodiment, the upper end of the support column 401 is rotatably sleeved with a flange 403 through a bearing. The installation plate 402 is fixedly installed on the flange 403 through bolts. Two connecting rods 202 are fixedly installed on the outer wall of the installation housing 201. The two connecting rods 202 are symmetrically arranged. A carrier table 3 for placing the plate to be painted is installed at one end of each of the two connecting rods 202 away from the installation housing 201. A driving component for driving the installation housing 201 to rotate is arranged on the base 4;

[0027] Specifically, the driving mechanism includes a first motor 204 and a toothed ring 203. The toothed ring 203 is fixedly installed on the inner wall of the installation housing 201. The first motor 204 is fixedly installed on the reinforcing rod 404 through a motor base. A gear 205 is fixedly installed on the rotating shaft of the first motor 204, and the gear 205 meshes with the toothed ring 203;

[0028] Specifically, a paint spraying tank body 5 is provided. When the robot 1 sprays paint on the board, the carrier table 3 rotates into the paint spraying tank body 5. A dilution tank is arranged at the lower part of the paint spraying tank body 5. A water pipe 6 is arranged at the upper end of the paint spraying tank body 5. A plurality of water flow holes are formed in the water pipe 6. A gas collecting pipeline is installed on the paint spraying tank body 5. One end of the gas collecting pipeline far away from the paint spraying tank body 5 is communicated with the air inlet of the negative pressure center.

[0029] By adopting the above scheme, during use, the water inlet of the water pipe 6 is connected to a water source through a water pump to make the water in the dilution tank at the lower part of the paint spraying tank body 5 in a flowing state. Then, the board to be painted is placed on the carrier table 3. Then, the first motor 204 is controlled to start, and the installation housing 201 is driven to rotate through the gear 205 and the toothed ring 203, so as to rotate the carrier table 3 with the board placed thereon above the dilution tank. Then, the robot 1 performs a paint spraying operation on the board. During the paint spraying, the paint exceeding the edge of the board falls back into the dilution tank. Due to the flowing water in the dilution tank, the paint is diluted by the flowing water and then discharged and collected, improving the processing environment. At the same time, through the arranged gas collecting pipeline, the paint gas floating in the paint spraying area can be centrally collected, further improving the air quality of the processing environment. After the paint spraying is completed, the first motor 204 is controlled to start to move the painted board out of the paint spraying area, and at the same time, the next board to be painted can be moved to the paint spraying area.

[0030] Specifically, in order to spray paint on the board in multiple directions and improve the paint spraying effect, a second motor 301 is fixedly installed at one end of the connecting rod 202 far away from the installation housing 201. The carrier table 3 is fixedly installed on the rotating shaft of the second motor 301. Through this setting, during the paint spraying, the second motor 301 can be controlled to drive the carrier table 3 to rotate, so as to spray paint on the board in multiple directions.

[0031] Specifically, the structure of the robot 1 in this embodiment can be the same as the structure of the six-joint paint spraying robot disclosed in the Chinese patent with the publication number of CN204911905U, and it is controlled by a PLC controller for both the first motor 204 and the second motor 301.
