If there are uneven areas on the surface of the painted part itself, it is difficult to achieve synchronous monitoring of the uneven areas using only one detection head. The detection head needs to move continuously to monitor the overall coating thickness of the uneven areas, which reduces the monitoring efficiency of the device. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example: See Figure 1 - Figure 4 As shown, the purpose of this embodiment is to provide an online monitoring device for the coating thickness of a coated part, including a workbench 1, a frame 2 is provided on the top surface of the workbench 1, and a monitoring mechanism 3 is provided on one side of the frame 2. The monitoring mechanism 3 includes a sliding plate 31 slidably arranged on one side of the frame 2, and the top of the sliding plate 31 is fixedly connected to a No. 1 motor 32, and the output shaft of the No. 1 motor 32 passes through the top surface of the sliding plate 31 and is transmission-connected to a central gear 33, and the central gear 33 is rotatably connected to the bottom surface of the sliding plate 31, and the bottom surface of the sliding plate 31 is fixedly connected to an outer gear ring 34, and the bottom surface of the sliding plate 31 is rotatably connected to a rotating plate 37, and the rotating plate 37 is rotatably arranged inside the outer gear ring 34, and the inner tooth surface of the outer gear ring 34 is meshed with three evenly distributed sub-gears 35, and the three sub-gears 35 are all rotatably connected to the bottom of the rotating plate 37, the top of the central gear 33 is rotatably connected to the bottom surface of the rotating plate 37, the central gear 33 is meshed with the three sub-gears 35, and the bottoms of the three sub-gears 35 are all fixedly connected to a coating detector 36.

[0022] A controller 4 is fixedly mounted on the top surface of the workbench 1 , and the three coating detectors 36 are all connected to the controller 4 via electrical signals.

[0023] In this embodiment, the first motor 32 controls the rotation of the central gear 33 and cooperates with the meshing action of the inner tooth surface of the fixed outer gear ring 34, so that the three sub-gears 35 revolve around the axis of the central gear 33, thereby driving the three coating detectors 36 to rotate. The coating detector 36 can emit laser and receive reflected light, and measure the coating thickness on the surface of the coated part by calculating the time of light reflection. This is a prior art and will not be described in detail here. After detection, the coating detector 36 transmits the data in the form of an electrical signal to the controller 4. The controller 4 analyzes the electrical signal and analyzes the data at three positions to quickly By locating the uneven positions on the surface of the painted part and setting up three rotatable coating detectors 36, the device can quickly scan and monitor the uneven surface of the painted part. The monitoring range of the three coating detectors 36 can effectively cover the unevenness of the painted part itself. When the traditional device uses a single detector for scanning monitoring, the laser of the detector is easily affected by the height change of the unevenness, which leads to errors in the measurement data. The three coating detectors 36 can simultaneously perform three-dimensional monitoring of the unevenness, which can effectively reduce the monitoring error of the device and improve the monitoring efficiency of the device.

[0024] In addition, in order to further improve the monitoring range of the monitoring mechanism 3, in this embodiment, the internal rotation of the frame 2 is connected to a screw rod 6, and one side of the frame 2 is fixedly connected to the No. 2 motor 5. One end of the screw rod 6 passes through one side of the inner wall of the frame 2 and is transmission-connected to the output end of the No. 2 motor 5. The sliding plate 31 is threadedly connected to the screw rod 6.

[0025] A guide rod 7 is fixedly connected to the interior of the frame 2 . The guide rod 7 is arranged parallel to the screw rod 6 . The sliding plate 31 is slidably connected to the guide rod 7 .

[0026] The top surface of the workbench 1 is fixedly connected to two symmetrically arranged slide rails 8, and the two ends of the bottom of the frame 2 are respectively slidably connected to the inside of the two slide rails 8. Both ends of the bottom of the frame 2 are fixedly connected to a plurality of rollers 9.

[0027] Two symmetrically arranged clamping plates 10 are slidably connected to the top surface of the workbench 1 .

[0028] In this embodiment, the No. 2 motor 5 controls the movement of the sliding plate 31 on the frame 2 by driving the screw rod 6 to rotate. The staff can also push the frame 2 to move in the slide rail 8. The moving direction of the frame 2 and the moving direction of the sliding plate 31 are perpendicular to each other in the horizontal plane, which can enable the monitoring range of the monitoring mechanism 3 to cover the surface of the painted part. The clamping plate 10 is used to clamp the painted part that needs to be monitored.

[0029] The working principle of this device is as follows: First, the staff places the painted part to be monitored on the workbench 1 and clamps it with the clamping plate 10. Then the staff turns on the three coating detectors 36 to irradiate the laser on the top surface of the painted part. During this process, even if there are unevenness on the surface of the painted part itself, the three coating detectors 36 can monitor the top surface of the painted part at the same time. If it is necessary to increase the monitoring range of the device, the staff can also turn on the No. 1 motor 32 to rotate the three coating detectors 36, so as to quickly scan and monitor the unevenness in a specific area. If it is necessary to further increase the monitoring range of the device, the staff can also turn on the No. 2 motor 5 to drive the screw 6 to rotate, so that the sliding plate 31 drives the three coating detectors 36 to move horizontally, and can also push the frame 2 to move on the slide rail 8, so that the device can monitor any position on the top surface of the painted part.
