[0025] Modern manufacturing industry has put forward efficient and accurate requirements for product paint surface inspection. However, traditional manual visual inspection methods are often difficult to meet these requirements due to their low efficiency and high cost. This method is not only limited by human interference, which is prone to problems such as missed inspections and wrong inspections, but also difficult to adapt to large-scale and high-efficiency production needs.

[0026] To this end, some embodiments of the present application provide a paint surface inspection device. In order to solve the problems of low efficiency and high cost of product paint surface inspection, the paint surface inspection device uses a turntable and a detachable mother-and-child fixture to rotate the product to be tested from the layout position to the sampling position, and then uses a clamping device to move the product to be tested to the inspection area, and in the inspection area, the paint surface of the product to be tested is fully inspected by using a light source and an inspection camera, and finally the product to be tested is placed back to the sampling position, and is rotated back to the layout position by a turntable to replace the next product to be tested. This can not only ensure the quality of product inspection, but also improve the inspection efficiency.

[0027] Combine the following Figures 1 to 3 , describing the paint surface inspection equipment provided in some embodiments of the present application.

[0028] like Figure 1 As shown, the paint surface detection equipment provided by some embodiments of the present application includes a workbench 10, a clamping device and a detection device. A turntable 11 is rotatably arranged on the workbench 10, and the edge of the turntable 11 changes between the setting-out position 12 and the sampling position 13. A plurality of mother fixtures 14 are fixedly arranged on the turntable, and each mother fixture 14 is connected to a detachable sub-fixture 15, and each sub-fixture 15 is used to place the product to be tested; the clamping device includes a mechanical arm 21 and a fixture 22 installed on the mechanical arm 21, and the fixture 22 is arranged near the sampling position 13, and the fixture 22 is used to clamp the sub-fixture 15 located at the sampling position 13, and move the product to be tested to the detection area under the drive of the mechanical arm 21; the detection device includes a light source 31 and a detection camera 32, and the light source 31 is used to emit detection light to the detection area, and the detection camera 32 is used to detect the paint surface of the product to be tested when the mechanical arm 21 drives the fixture 22 to move.

[0029] A turntable 11 is rotatably provided on the workbench 10, and the edge of the turntable 11 can be switched between the layout position 12 and the sampling position 13. By rotating the turntable 11, the product to be tested can be switched between the layout position 12 and the sampling position 13. A plurality of mother jigs 14 can be fixedly provided on the turntable 11, and each mother jig 14 is connected to a detachable sub-jig 15, and each sub-jig 15 can be used to place the product to be tested. The operator only needs to place the product to be tested on the sub-jig 15 located at the layout position 12 at the layout position 12, and the product to be tested can be transferred to the sampling position 13 as the turntable 11 rotates, thereby simplifying the operation process.

[0030] like Figure 1 As shown, at least two or more combinations of mother jigs 14 and sub-jigs 15 are arranged on the workbench 10 to ensure the high efficiency of continuous operation. When one of the mother jigs 14 is in the placement position 12, the operator can quickly place the product to be tested on the sub-jig 15 connected to the mother jig 14, and then the turntable 11 rotates to transfer the mother jig 15 and the sub-jig 16 carrying the product to be tested to the sampling position 13. In this way, the product to be tested can be transferred between different positions, and the operation is simple, and the placement and detection process is completed efficiently. In addition, since the sub-jig 15 is designed to be detachable, the placement and removal of the product becomes easy and convenient, further improving the overall work efficiency.

[0031] The clamping device includes a mechanical arm 21 and a clamp 22 mounted on the mechanical arm. The mechanical arm 21 is a controllable device with multiple joints and degrees of freedom, which can move accurately according to a preset path and action. The clamp 22 is an actuator installed at the end of the mechanical arm 21, which is used to firmly clamp the product to be tested. The clamp 22 can be set at a position close to the sampling position 13. When the turntable 11 transfers the product to be tested to the sampling position 13, the mechanical arm 21 can drive the clamp 22 to the sampling position 13 and clamp the sub-jig 15 located at the sampling position 13. Since the product to be tested has been placed on the sub-jig 15, once the clamp 22 successfully clamps the sub-jig 15, the mechanical arm 21 can smoothly move the product to be tested to the detection area according to the preset action path. The clamping device can not only prevent the clamp 22 from being damaged by direct contact with the product to be tested, but also ensure that the product to be tested is accurately transferred to the detection area through the operation of the mechanical arm 21 and the clamp 22, thereby improving the detection efficiency and accuracy.

[0032] The detection device includes a light source 31 and a detection camera 32. The size of the light source can be 55 inches to provide a sufficient lighting range. After the fixture 22 reaches the detection area, the light source 31 can emit stripe detection light to the detection area, and the stripe light will be irradiated on the paint surface of the product to be tested. The detection camera 32 can be used to detect the paint surface of the product to be tested when the mechanical arm 21 drives the fixture 22 to move. The stripe detection light is usually composed of a series of parallel light and dark stripes. The characteristic of this light source is that it can form high-contrast stripes on the surface, which is conducive to the analysis and measurement of the surface morphology in subsequent image processing. In paint surface detection, the stripe light can make the bumps, flaws and other features on the paint surface more clearly displayed, which helps the detection camera 32 to capture more detailed information.

[0033] The embodiments of the present application do not limit the product to be tested. The product to be tested can be any product. For example, the product can be a certain model of automobile parts, decorative strips, mobile phones, computers, smart speakers, LCD panels, etc., and the present disclosure does not limit this.

[0034] like Figure 2 As shown, in some embodiments, each mother fixture 14 may include a support plate 141 for placing the child fixture 15 and a plurality of support columns 142 supporting the support plate 141 , and one end of each support column 142 may be fixed on the turntable 11 .

[0035] The support plate 141 can provide a stable placement surface for the sub-jig 15, so that the sub-jig 15 can be firmly placed on the support plate 141. The support column 142 is used to support the support plate 141. There can be multiple support columns 142, which are evenly distributed under the support plate 141 to ensure the stability and firmness of the support plate 141. The bottom end of each support column 142 is fixed on the turntable 11. When the turntable 11 rotates, the mother jig 14 and the sub-jig 15 thereon will move with the turntable 11.

[0036] In some embodiments, each support plate 141 may be provided with an electromagnet.

[0037] An electromagnet is a device whose magnetism can be controlled by electric current. The electromagnet is arranged in the support plate 141, which means that the magnetism of the electromagnet can be turned on or off by controlling the electric current. When the electromagnet is turned on, a magnetic force can be generated, which can be used to adsorb or fix the sub-jig 15 placed on the support plate 141. This magnetic adsorption method can provide a stable and firm fixing effect, especially when the turntable 11 rotates at high speed or performs other intense operations, it can effectively prevent the sub-jig 15 from moving or slipping.

[0038] At the same time, the magnetism of the electromagnet can be quickly switched by controlling the current. This means that when the sub-jig 15 needs to be replaced or moved, the magnetism of the electromagnet can be quickly turned off so that the sub-jig 15 can be removed from the support plate 141. When the sub-jig 15 needs to be fixed, the magnetism of the electromagnet can be turned on to achieve rapid fixation. This fast and convenient operation method greatly improves the operating efficiency and flexibility of the paint surface inspection equipment.

[0039] In some embodiments, the clamp 22 may be an electromagnetic clamp.

[0040] Electromagnetic clamps can clamp and release workpieces through electromagnetic force, and have the characteristics of fast response speed, low energy consumption, and environmental protection. Electromagnetic clamps have large clamping force and high precision, and are easy to operate, with adjustable clamping force and are not easy to damage the surface of the product to be tested.

[0041] In some embodiments, each sub-jig 15 may include a base plate 151 and a connecting plate 152 , the connecting plate 151 of each sub-jig 15 may be fixedly disposed on the base plate 152 , and the base plate 152 and the connecting plate 151 of each sub-jig 15 may be provided with an electromagnet.

[0042] The bottom plate 151 is the bearing platform of the sub-jig 15, ensuring that the product to be tested can be firmly placed on the sub-jig 14. The connecting plate 152 has a shape and size that is compatible with the electromagnetic clamp. The bottom plate 152 and the connecting plate 151 of each sub-jig 15 can be provided with an electromagnet. When the sub-jig 15 is placed on the support plate 141, by controlling the current, the electromagnet in the bottom plate 152 can generate magnetic adsorption with the support plate 141, thereby ensuring the stable placement of the sub-jig 15 on the support plate 141 and preventing it from being thrown off during the rotation of the turntable 11. When it is necessary to clamp the sub-jig 15 for paint surface inspection, by turning off the current of the support plate 141, the magnetic force between the bottom plate 152 and the support plate 141 can be eliminated, so that the sub-jig 15 can be smoothly detached from the support plate 141. Subsequently, the fixture 22 starts working. By controlling the current in the fixture 22, the electromagnet inside it can generate strong magnetic attraction with the electromagnet in the connecting plate 152, thereby accurately and firmly clamping the connecting plate 152. After the paint surface inspection is completed, by turning off the current in the fixture 22, the magnetic force between the electromagnet inside it and the connecting plate 152 disappears, allowing the sub-jig 15 to smoothly detach from the fixture 22. Finally, by restoring the current of the support plate 141, the bottom plate 152 generates magnetic attraction with the support plate 141 again, so that the sub-jig 15 returns to the support plate 141, waiting for the operator to replace the next product to be tested at the layout position 12.

[0043] In some embodiments, the clamp 22 may be provided with a positioning pin, and each connecting plate 152 may be provided with a positioning hole. The clamp 22 may be inserted into the positioning hole through the positioning pin 152 to locate the position of the sub-jig 15 .

[0044] The fixture 22 may be equipped with a positioning pin, and a positioning hole may be provided on each connecting plate 152. When the paint surface inspection is required, the positioning pin of the fixture 22 will be accurately inserted into the positioning hole on the connecting plate 152, thereby ensuring that the sub-jig 15 is accurately clamped by the fixture 22.

[0045] In some embodiments, each sub-jig 15 may be provided with a vacuum suction cup 153 , and the vacuum suction cup 153 may be used to fix the product to be tested.

[0046] The vacuum suction cup 153 can firmly fix the product to be tested on the sub-jig 15 by generating negative pressure to prevent it from loosening or falling off during the movement.

[0047] In some embodiments, the detection device may further include a plurality of first sensors 33 disposed on each mother fixture 14 , and the plurality of first sensors 33 may be used to detect the model of the product to be detected.

[0048] A number of first sensors 33 greater than or equal to one can be provided on each mother fixture 14, and a plurality of first sensors 33 can be used to detect the model of the product to be tested. The plurality of first sensors 33 can identify the model of the product to be tested by different parameters or features. Once the model is determined, the working mode of the detection camera 32 can be adjusted according to the preset detection parameters to ensure accurate and efficient detection of the paint surface of products of different models.

[0049] like Figure 3 As shown, the paint surface inspection device may further include a housing 40 , and the housing 40 may be provided with an intelligent panel 41 and an openable and closable operating panel 42 .

[0050] The smart panel 41 can be used to display the device status, operation interface or other related information, and the operator can interact with the device by touching or pressing keys, such as setting detection parameters, viewing detection results, etc. At the same time, the smart panel 41 can also display the operating status and fault information of the device in real time, helping users to understand the working status of the device in a timely manner.

[0051] The openable and closable operation panel 42 provides a convenient way to maintain and operate the inside of the equipment. When it is necessary to place the product to be tested or to perform equipment maintenance, the operator can easily open the operation panel 42 to expose the working area inside the equipment. When the equipment is operating normally, the operation panel 42 can be closed to protect the parts inside the equipment from interference and damage from the external environment.

[0052] In some embodiments, the detection device further includes a second sensor 34 disposed on the operation panel 42 , and the second sensor 34 can be used to detect the color of the product to be detected.

[0053] The second sensor 34 can detect the color of the product to be tested. By detecting the color of the product, the system can further accurately adjust the parameters and algorithms of the paint surface detection to adapt to products of different colors and ensure the accuracy and reliability of the detection results.

[0054] In actual operation, the operator first opens the operating panel 42 of the housing 40, and places the product to be tested on the sub-jig 15 located at the layout position 12. The product to be tested is fixedly connected to the sub-jig 15 through the vacuum suction cup 153. At this time, the second sensor 34 on the operating panel 42 detects the color of the product to be tested, and the first sensor 33 detects the model of the product to be tested. After collecting the color and model of the product to be tested, the operator adjusts the parameters of the detection camera 32 through the smart panel 41. The product to be tested rotates from the layout position 12 to the sampling position 13 through the turntable 11. During this process, the support plate 141 remains energized so that the sub-jig 15 and the mother jig 14 are adsorbed to each other to prevent the sub-jig 15 from falling during the rotation. After the product to be tested reaches the sampling position 13, the clamping device is energized to generate magnetism, and the sub-jig 15 is adsorbed to the fixture 22, thereby moving the product to be tested to the detection area. After the light source 31 and the detection camera 32 have performed an all-round inspection on the product to be tested, the clamping device moves the sub-jig 15 back to the sampling position 13, and cancels the power to eliminate the magnetism of the clamp, so that the sub-jig 15 and the product to be tested are placed back on the mother jig 14, and the product to be tested is rotated back to the sampling position 12 through the turntable 11. The operator takes out the product to be tested and replaces it with the next product to be tested.

[0055] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present application, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present application.
