[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0023] refer to Figure 1-5The present invention discloses a large-area spraying robot, comprising a frame 1, on which symmetrically rotating casters 2 are provided, and a servo motor driving the casters 2 to rotate is provided at the bottom of the frame 1. A magnetic suction device is provided at the bottom of the frame 1 to allow the robot to adhere to an iron wall. A fixed frame 4 is provided on the frame 1, and a spraying frame 6 is connected to the fixed frame 4. The spraying frame 6 is located outside the frame 1. Two nozzles 12 are provided on the spraying frame 6 through a connecting device. A pressure reducing valve 4 and a solenoid valve 5 are provided on the frame 1 and connected to the nozzles 12. The pressure reducing valve 4 is used to adjust the spray pressure of the nozzles 12, and the solenoid valve 5 is used to control the opening and closing of the nozzles 12. A control box 3 is also provided on the frame 1 to receive signals and control the robot.

[0024] Specifically, the connecting device includes symmetrically arranged T-shaped blocks 14, and a plurality of connecting rails 18 symmetrically arranged on the spray frame 6. The T-shaped blocks 14 are bolted to the connecting rails 18. Each T-shaped block 14 has a longitudinal slot 15 through which the bolt passes and is locked to the connecting rail 18. A connecting rod 13 is provided between the T-shaped blocks 14, and the spray head 12 is mounted on the connecting rod 13. Each T-shaped block 14 has a transverse slot 16, and the end of the connecting rod 13 is locked within the transverse slot 16. When the spray head 12 is installed, its height and position can be adjusted using the T-shaped blocks 14 and the connecting rod 13, allowing for better painting.

[0025] To prevent paint from scattering and polluting the environment during spraying due to external interference with the spray nozzles 12, the spray frame 6 is equipped with a spray cover 10. The spray cover 10 has spray holes for the spray nozzles 12 to pass through, matching the number of nozzles 12. By covering the spray nozzles 12 with the spray cover 10, the spray nozzles 12 are not affected by wind or other factors during spraying, and any scattering paint falls directly onto the spray cover 10, thereby reducing environmental pollution.

[0026] Specifically, the magnetic attraction device includes a yoke 19 for suppressing the divergence of magnetic field lines and a connecting block 20. A plurality of magnets 18 are locked onto the yoke 19, which is then locked onto the connecting block 20. The magnets 18 are arranged in a Helbeck array.

[0027] The connecting block 20 is locked to the bottom of the frame 1. The yoke 19 suppresses the upward movement of magnetic field lines, causing the magnetic field lines of the magnet 18 to point downwards, thus better attracting the robot to the iron wall and allowing it to firmly adhere to the wall during climbing. The use of a Hellbeck array further enhances the magnetic attraction, enabling the robot to climb more effectively.

[0028] To protect the magnet 18 from damage, a protective cover 17 is also included. The protective cover 17 is placed over the magnet 18 to protect it. The protective cover 17 is fastened to the magnet 18 by screws.

[0029] Preferably, the protective cover 17 is a stainless steel protective cover 17.

[0030] To enable the robot to pass through obstacles more effectively, the magnet 18 is arranged in an arc shape. This arc shape prevents the magnet from directly hitting obstacles, allowing it to pass through from the bottom more easily.

[0031] In order to enable the robot to climb better, the frame 1 is equipped with casters 11 behind the moving wheels 2.

[0032] In order to better connect the connecting block 20 to the frame 1, a gasket is provided between the connecting block 20 and the frame 1.

[0033] Working principle:

[0034] In operation, the painting robot is placed on an iron wall, and a magnetic attachment device holds it in place. The servo motor on the robot activates, rotating its two wheels. The operator then remotely controls the robot from below, moving it along the iron wall. Once at the designated spraying position, the operator operates the spray gun to apply the paint. After spraying, the device is shut off, and the robot returns to its initial position. The spraying equipment and work area are then cleaned, completing one painting operation. Using a painting robot not only achieves painting but also eliminates the need for workers to work at heights, thus protecting their health. Furthermore, the robot can operate 24 hours a day, significantly improving spraying efficiency. It also prevents workers from coming into contact with harmful substances, protecting their health.
