High-definition camera photo recognition is used instead of human eye recognition, with a high degree of standardization, and the detection accuracy can be accurate to within an error of plus or minus 0.01 square millimeter.

[0027] The camera 2 and lens 3 are each mounted on a vertically arranged bracket 1 .

[0028] Two installation plates 5 are arranged on both sides of the lens 3, one end of the installation plate 5 is connected with the support 1, and the other end of the installation plate 5 extends to the side of the light source 4 away from the support 1, two installation plates 5 are connected with a carrier plate 6 between the ends away from the support 1, and a clamping seat 7 for mounting the mobile phone 8 is arranged on the carrier plate 6.

[0029] A cylinder 9 is arranged on the side surface of one of the installation plates 5 away from the support 1, and the light source 4 is arranged on the movable part of the cylinder 9 through a movable plate 10.

[0030] A guide rail 11 parallel to the extension direction of the cylinder 9 is arranged on the side surface of the other installation plate 5 away from the support 1, and at least one sliding block 12 slidingly matched with the guide rail 11 is connected with the movable plate 10.

[0031] Embodiment 2: A visual detection assembly, comprising: a camera 2, a lens 3 and a light source 4 arranged in sequence in the vertical direction, the lens 3 is mounted on the camera 2, the light source 4 is arranged away from the lower end surface of the lens 3, a mobile phone 8 is arranged above the light source 4 and on one side of the lens 3, the camera 81 of the mobile phone 8 is arranged towards the light source 4, the light source 4 is movably arranged below the lens 3 and the camera 81 of the mobile phone 8, and when moved to a first position, the light source 4 is directly below the lens 3, and when moved to a second position, the light source 4 is directly below the camera 81 of the mobile phone 8.

[0032] One end of the camera 81 of the mobile phone 8 is arranged close to the lens 3.

[0033] The camera 2 and the lens 3 are each mounted on a vertically arranged support 1.

[0034] The camera 2 and the support 1 are connected through a mounting block 13, and a clamp 141 is sleeved outside the lens 3, the clamp 141 is mounted on the support 1 through two spaced support blocks 142.

[0035] Example 3: A detection device, comprising: a carrier 200 for loading a product 100 to be detected, a wiping assembly and a visual detection assembly, the wiping assembly comprising: a wiping block 15 located below the visual detection assembly, a cloth placing module 20 and a cloth collecting module 21, a wiping cloth 19 wound around the cloth placing module 20, the wiping block 15 and the cloth collecting module 21, the end of the wiping block 15 is provided with a wiping head 16 for contacting the product 100 to be detected through the wiping cloth 19, and the area where the wiping block 15 is close to the wiping head 16 is spaced apart along the width direction of the wiping cloth 19. A plurality of liquid outlet holes 17 in contact with the wiping cloth 19 are provided. In the movement direction of the wiping cloth 19, the above-mentioned liquid outlet holes 17 are located on the side of the wiping head 16 close to the cloth placing module 20. The above-mentioned liquid outlet holes 17 are connected to the liquid flow channel 18 provided in the wiping block 15. The liquid flow channel 18 is connected to the liquid supply unit through a pipeline. The test liquid injected into the liquid flow channel 18 is generally 90% ethanol, methanol and other liquids that can evaporate quickly and leave no residue. The test liquid overflowing from the liquid outlet soaks the wiping cloth and then wipes the surface of the product 100 to be tested evenly.

[0036] The working principle is:

[0037] Used to detect defects on the coated surface of glass products (such as the glass back panel of electronic products). The coated surface is the surface to be wiped and the surface to be tested.

[0038] First, install the rolled strip of wiping cloth on the cloth placing module, then pass one end of the wiping cloth around the wiping block and wiping head in sequence and install it on the cloth collecting module;

[0039] The wiping cloth can be driven by the cloth collecting module to move from the cloth feeding module to the cloth collecting module, so that during the movement, one side surface of the wiping cloth successively slides in contact with the liquid outlet area on the wiping block and the outer surface of the wiping head;

[0040] Liquid (such as alcohol) is injected into the liquid flow channel on the wiping block through a pipeline, and the liquid can overflow from the liquid outlet to soak the wiping cloth wrapped around the wiping block and outside the liquid outlet;

[0041] During the test, the product to be tested is loaded onto the carrier with the coated surface facing upwards;

[0042] The product to be inspected is first moved under the camera using a carrier. The wiping head then drives a wiping cloth soaked in the inspection liquid to wipe the coated surface of the product to be inspected. The light source is then moved directly under the lens, and the camera takes a picture of the product's coated surface. Image data of the intact and defective coating areas formed by the inspection liquid that evaporates and dissipates over a certain period of time is captured, thereby completing the capture of defect morphology and laying the preliminary physical foundation for the accurate recognition of deep learning algorithms. The recognition algorithm for coating defect detection does not fall within the scope of this patent and will not be further described here.

[0043] With the improvement of the camera function of smart electronic products, more and more smartphone cameras can meet the needs of high-definition shooting for visual inspection. However, the cost of industrial cameras is high. Therefore, when the camera is faulty or missing, the mobile phone can be installed on the clamping seat and the light source can be moved under the camera of the mobile phone. The mobile phone with high-definition camera function can be used for shooting and inspection, and the accuracy and clarity of the shooting can be guaranteed.

[0044] When using the above-mentioned visual inspection component, it can use the mobile reuse of the light source to perform visual inspection by taking pictures with a high-definition camera, and can also use a smartphone with a high-definition lens instead of a camera for inspection. The movement of the light source ensures the accuracy and clarity of the pictures taken by the camera and the mobile phone, thereby reducing the inspection cost and improving the flexibility of inspection.

[0045] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention are intended to be included in the scope of protection of the present invention.
