[0035] Example 1

[0036] The embodiment is basically as shown in the attached Figures 1 to 6 As shown: an automatic painting device, comprising a mounting frame 1 and a frame 21 clamping a wood 2, a first conveyor belt 4 and a second conveyor belt 5 are arranged in the mounting frame 1, the second conveyor belt 5 is located on both sides of the first conveyor belt 4, and the first conveyor belt 4 and the second conveyor belt 5 are arranged along the feeding direction of the wood 2;

[0037] A plurality of alternately arranged first placement rods 22 and second placement rods 23 are clamped on the frame 21. The frame 21 is composed of two symmetrical frame 21 plates. A groove is provided between adjacent frame 21 plates. Bolts 211 are threadedly connected in the groove. The frame 21 is fixedly connected to the wood 2 by the bolts 211. The length of the second placement rods 23 is greater than that of the first placement rods 22. The first placement rods 22 and the second placement rods 23 are on different horizontal planes. The frame 21 is placed on the first conveyor belt 4 through the first placement rods 22, and the frame 21 is placed on the second conveyor belt 5 through the second placement rods 23.

[0038] A turning mechanism is also provided on both sides of the mounting frame 1. The turning mechanism includes a plurality of rotating shafts 31 that are rotatably matched with the mounting frame 1. The rotating shafts 31 are located on both sides of the first conveyor belt 4, and the rotating shafts 31 are located on the side of the first conveyor belt 4 close to the second conveyor belt 5. A motor 3 is coaxially connected to one end of the rotating shaft 31. A clamping mechanism 32 for clamping the frame 21 is provided inside the rotating shaft 31. The clamping mechanism 32 is a hydraulic cylinder.

[0039] A plurality of spray heads 12 are fixedly connected to the top of the mounting frame 1.

[0040] The specific implementation process is as follows: first, the wood 2 is manually fixed through the frame 21 so that the first placement rod 22 of the frame 21 contacts the first conveyor belt 4, and then the wood 2 and the frame 21 are placed on the first conveyor belt 4 for transportation, and the first side of the wood 2 is sprayed with paint through several paint spray heads 12 on the top of the mounting frame 1.

[0041] When the first conveyor belt 4 transports the frame 21 to the flipping mechanism, the two ends of the frame 21 are clamped by the clamping mechanism 32, and then the motor 3 is started to drive the rotating shaft 31 to rotate, so that the wood 2 is turned over. When the frame 21 rotates around the rotating shaft 31, since the second conveyor belt 5 is located on both sides of the first conveyor belt 4, and the length of the second placing rod 23 is greater than the length of the first placing rod 22, the first placing rod 22 and the second placing rod 23 are on different horizontal planes; therefore, the second placing rod 23 of the frame 21 will contact the second conveyor belt 5, so that the frame 21 is placed on the second conveyor belt 5, and the second side of the wood 2 is sprayed with paint through a plurality of spray heads 12 on the top of the mounting frame 1.

[0042] Through the cooperation of the first conveyor belt 4, the second conveyor belt 5, the clamping mechanism 32 and the turning mechanism, it is convenient to spray paint on both sides of the wood 2. At the same time, the wood 2 can be automatically replaced to improve work efficiency.

[0043] Example 2

[0044] The difference from the above embodiment is that a concave buffer pad 321 is welded to the output end of the clamping mechanism 32 , and the buffer pad 321 is made of rubber.

[0045] The specific implementation process is as follows: the buffering effect of the buffer pad 321 is used to reduce the squeezing of the clamping mechanism 32 on the frame 21, so that the frame 21 is not easily deformed, and the concave buffer pad 321 is adsorbed on the frame 21 during the contact process with the frame 21, so that the clamping mechanism 32 can fix the frame 21.

[0046] Example 3

[0047] The difference from the above embodiment is that the buffer pad 321 is connected to the air pipe 322, and the end of the air pipe 322 away from the buffer pad 321 passes through the rotating shaft 31. The air pipe 322 is also connected to the solenoid valve 323, and the solenoid valve 323 is electrically connected to the control panel (not shown in the figure).

[0048] The specific implementation process is as follows: when the clamping mechanism 32 needs to loosen the clamping of the frame 21, the control panel controls the opening and closing of the solenoid valve 323 on the air pipe 322 to connect the negative pressure inside the rubber pad with the outside world, achieve air pressure balance, and make the buffer pad 321 adsorbed on the surface of the frame 21 release the frame 21.

[0049] Example 4

[0050] The difference from the above embodiment is that the bottom of the mounting frame 1 is funnel-shaped.

[0051] The specific implementation process is as follows: the bottom of the funnel-shaped mounting frame 1 is convenient for collecting excess paint, thereby improving resource utilization.

[0052] Example 5

[0053] The difference from the above embodiment is that a plurality of ball screw mechanisms 11 are fixedly connected to the top of the mounting frame 1 by bolts 211, the bottom of the nut seat of the ball screw mechanism 11 is welded to the paint spray head 12, and the screw of the ball screw mechanism 11 is parallel to the feeding direction of the wood 2.

[0054] The specific implementation process is as follows: the paint spraying head 12 is driven by the ball screw to move back and forth along the feeding direction of the wood 2, so that the paint spraying head 12 can spray paint on the wood 2 back and forth to make the paint surface more uniform.

[0055] Example 6

[0056] The difference from the above embodiment is that a blocking block 6 is provided between the first conveyor belt 4 and the second conveyor belt 5, the blocking block 6 is fixedly connected to the mounting frame 1, a second pressure sensor is fixedly connected to the blocking block 6, and the second pressure sensor is electrically connected to the control panel.

[0057] The specific implementation process is as follows: when the first conveyor belt 4 transports the wood 2 and the frame 21 to the blocking block 6, the frame 21 will apply pressure to the second pressure sensor on the blocking block 6, and the first pressure sensor 231 is used to detect the first pressure data of the second placement rod 23 in real time, and send the first pressure data to the control panel, and the control panel sends a rotation instruction to the first conveyor belt 4, the clamping mechanism 32 and the motor 3 based on the first pressure data. The rotation instruction includes an operating sequence. The first conveyor belt 4 stops working based on the rotation instruction, and the clamping mechanism 32 is started based on the rotation instruction, so that the clamping mechanism 32 clamps the two sides of the frame 21, and then, the motor 3 drives the rotating shaft 31 to rotate based on the operating sequence of the rotation instruction, thereby driving the frame 21 and the wood 2 to turn over.

[0058] Example 7

[0059] The difference from the above embodiment is that the second placement rod 23 is clamped with a first pressure sensor 231 , and the first pressure sensor 231 is electrically connected to the control panel.

[0060] The specific implementation process is as follows: when the frame 21 and the wood 2 are turned over, the second placement rod 23 will contact the second conveyor belt 5 before the first pressure sensor 231 is used to detect the first pressure data of the second placement rod 23 in real time, and send the first pressure data to the control panel. The control panel sends a release command to the clamping mechanism 32 based on the first pressure data. The clamping mechanism 32 starts in reverse based on the release command, so that the clamping mechanism 32 no longer clamps the frame 21, so that the frame 21 and the wood 2 fall onto the second conveyor belt 5, which is convenient for the subsequent second conveyor belt 5 to transport the frame 21 and the wood 2.
