[0020] Example 1: A magnetic spraying robot, such as Figure 1-3 As shown, the robot body 1 includes a moving mechanism 2, which includes a magnetic wheel 201. The moving mechanism 2 is used to roll against the metal surface through the magnetic wheel 201 and drive the robot body 1 to move through the magnetic wheel 201. For technical personnel in the relevant field, the moving mechanism 2 and the magnetic wheel 21 are both well-known technologies, so they will not be described in detail.

[0021] A transmission box 3 is fixedly provided at the top of the robot body 1, and a driving mechanism 4 is provided in the transmission box 3. Two spray heads 5 are provided on the driving mechanism 4. The spray heads 5 are fixedly connected and communicated with a material delivery pipe, which is connected to a feeding system. The feeding system is used to deliver paint to the spray heads 5 through the material delivery pipe. For technicians in the relevant field, the feeding system is a well-known technology, so no more details are given. The driving mechanism 4 is used to drive the spray heads 5 to move back and forth in the left and right directions to achieve range spraying. Specifically, the driving mechanism 4 includes a driving motor 401 fixedly provided in the robot body 1, and the output shaft of the driving motor 401 penetrates into the transmission box 3 and is fixed with a first spur gear 402. Two rotating shafts 403 spaced apart on the left and right are rotatably provided in the transmission box 3, and a second spur gear 404 is fixedly sleeved on the rotating shaft 403. The two second spur gears 404 are respectively located on the left and right of the first spur gear 402, and the first spur gear 402 is meshed with the second spur gear 404. The front end of the rotating shaft 403 passes through The second spur gear 404 is fixed with an active rod 405, and the active rod 405 is hinged with a driven rod 406 at one end away from the rotating shaft 403. The driven rod 406 is rotatably provided with a gear shaft 408 at one end away from the active rod 405. The front end of the gear shaft 408 passes through the driven rod 406 and is fixed with a third spur gear 409. A fixed rack 410 is fixed in the transmission box 3, and a sliding rack 411 is slidably provided in the transmission box 3. The fixed rack 410 and the sliding rack 411 are arranged at an interval up and down. The gear 409 is located between the fixed rack 410 and the sliding rack 411, and the third spur gear 409 is respectively engaged with the fixed rack 410 and the sliding rack 411. The end of the sliding rack 411 can pass through the transmission box 3. A guide slider 412 is fixed on the sliding rack 411. The front side of the transmission box 3 is provided with a slide groove 413 extending in the left and right directions and transparent inside and outside. The guide slider 412 slides through the slide groove 413. The front end of the guide slider 412 passes through the slide groove 413 and is provided with a spray head 5.

[0022] When the output shaft of the driving motor 401 drives the first spur gear 402 to rotate, it can drive the second spur gear 404 to rotate, and the second spur gear 404 drives the active rod 405 to rotate. During the circumferential rotation, the active rod 405 drives the gear shaft 408 and the third spur gear 409 to move back and forth between the fixed rack 410 and the sliding rack 411 through the driven rod 406. At the same time, the third spur gear 409 is rotated by the action of the fixed rack 410 to push the sliding rack 411 to slide left and right, thereby driving the guide slider 412 and the spray head 5 to move left and right to perform range spraying operations.

[0023] The two active rods 405 on the left and right are parallel to each other, and the two spray heads 5 are symmetrically arranged, so that the two active rods 405 can drive the two spray heads 5 to move in relative or opposite directions at the same time, which can avoid the center of the robot body 1 from being offset and reduce the load on the robot body 1.

[0024] The inner wall of the transmission box 3 is fixedly provided with a slide rail 8, and the sliding rack 411 is slidably provided on the slide rail 8 to guide the sliding rack 411 and the spray head 5 to slide in the left and right directions.

[0025] The middle part of the transmission box 3 is a cylindrical structure, which can increase the rotation space for the active rod 405, and the length of the active rod 405 is smaller than the distance between the rotating shaft 403 and the driving motor 401 to avoid collision between the left and right active rods 405.

[0026] The fixed rack 410 on the left is located below the transmission box 3, the fixed rack 410 on the right is located above the transmission box 3, the sliding rack 411 on the left is located above the transmission box 3, and the sliding rack 411 on the right is located below the transmission box 3, and the sliding rack 411 and the fixed rack 410 are staggered front and back, and the sliding rack 411 is located in front of the fixed rack 410, so that when the spray head 5 and the guide slider 412 are located at the end of the sliding rack 411 away from the transmission box 3, the sliding rack 411 can slide in a larger range, further increasing the spraying range of the spray head 5.

[0027] The guide slider 412 on the left is fixed with an L-shaped bracket 6 extending downward, and the guide slider 412 on the right is fixed with an L-shaped bracket 6 extending upward. The ends of the two L-shaped brackets 6 are fixed with U-shaped clamps 7. The spray head 5 is fixedly clamped on the L-shaped bracket 6. The left and right U-shaped clamps 7 are located in the same horizontal plane, so that the left and right spray heads 5 are located in the same horizontal plane, so as to avoid different distances between the two spray heads 5 and the spraying surface, resulting in poor spraying effect.

[0028] Working principle: When in use, the robot body 1 is rolled and adsorbed on the wall through the magnetic wheel 201 in the moving mechanism 2, and then the driving motor 401 is started. The output shaft of the driving motor 401 drives the first spur gear 402 to rotate, and then drives the second spur gear 404 to rotate. The second spur gear 404 drives the active rod 405 to rotate. During the circumferential rotation, the active rod 405 drives the gear shaft 408 and the third spur gear 409 to move back and forth between the fixed rack 410 and the sliding rack 411 through the driven rod 406. At the same time, the third spur gear 409 is rotated by the fixed rack 410 to push the sliding rack 411 to slide left and right, and then drive the guide slider 412 and the spray head 5 to move left and right to perform range spraying operations. At the same time, the magnetic wheel 201 in the moving mechanism 2 is controlled to roll periodically to drive the robot body 1 to move on the spraying surface for spraying operations.
