[0002] With the rapid development of industrial manufacturing technology, optical products are widely used in various precision instruments and daily life. Minor defects on the optical surface often lead to a decline in optical performance and even affect the use of the entire product. In the manufacturing industry, surface defect detection is an important link in ensuring product quality. At present, there are a variety of optical visual surface defect detection devices on the market, most of which use fixed cameras and light source configurations to adapt to specific detection tasks. However, this fixed configuration method is difficult to flexibly adjust when facing products of different shapes, sizes and surface characteristics due to different surface detection positions. Therefore, its detection effect is often unsatisfactory, and there are problems such as low detection accuracy, poor adaptability, and complex operation.

[0003] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses an optical visual surface defect detection device. Figure 1-Figure 2, including a detection frame 1, an optical detector 18 installed in the detection frame 1, the optical detector 18 is a device that uses optical principles to detect the properties, characteristics or states of an object, and can use optical sensors and related technologies to obtain information about the object being tested by measuring the characteristics of light, and can detect defects on the surface of the product. A protective cover 2 is fixedly connected to the bottom of the detection frame 1, and the protective cover 2 is set on the outside of the optical detector 18 to protect it. An installation cavity 6 is opened in the detection frame 1, and a group of mounting parts 7 are connected to the inner wall of the installation cavity 6 by screws. An adaptive limit sleeve 8 is fixed to the outside of the mounting part 7, and an adaptive movable link 9 is provided inside the limit sleeve 8.

[0020] A motor 3 is installed on the side wall of the detection frame 1. The output end of the motor 3 passes through the inner wall of the detection frame 1 and is connected to the rotating shaft 10. A gear 11 is symmetrically fixed to the outside of the rotating shaft 10. The surface of the movable connecting rod 9 is evenly distributed with a number of tooth blocks 13 meshing with the gear 11. Therefore, when the rotating shaft 10 drives the gear 11 to rotate, it can mesh with the tooth block 13, and then the movable connecting rod 9 can be pushed to slide up and down in the limiting sleeve 8. Since the top ends of the two movable connecting rods 9 are both integrally structured and fixed with the limiting blocks 14, they have a limiting effect.

[0021] Since the bottom of the detection frame 1 is symmetrically provided with movable holes 12, the movable holes 12 extend into the interior of the protective cover 2, and the ends of the two movable connecting rods 9 away from the detection frame 1 extend into the protective cover 2 and are fixed with connecting seats 15, the connecting seats 15 can be driven to change in height accordingly as the movable connecting rods 9 slide up and down.

[0022] like Figure 3 As shown, screws 16 are threadedly connected to both sides of the outer wall of the connecting seat 15, one end of the screw 16 extends to the outside of the connecting seat 15 and is movably connected to a clamping plate 17 adapted to the optical detector 18. The clamping space between the clamping plate 17 and the connecting seat 15 can be adjusted by adjusting the screw 16, so as to facilitate the installation and fixation of the optical detector 18.

[0023] In addition, a slider 4 is fixed at the center of the top of the detection frame 1, and a detection slide rail 5 is slidably arranged in the slider 4. The detection slide rail 5 can be fixed in advance, so that the detection frame 1 can be set up on the surface of the product for detection.

[0024] The implementation principle of an optical visual surface defect detection device in the embodiment of the present application is as follows: when in use, the detection slide rail 5 is fixed to a certain height in advance and can be used in conjunction with an external support frame. The detection frame 1 can be set up on the upper part of the product through the connection of the slider 4. During the detection process, the slider 4 is pushed to move horizontally outside the detection slide rail 5, so that the detection position can be continuously adjusted according to needs. The motor 3 can also drive the rotating shaft 10 to drive the gear 11 to move forward and reverse in the installation cavity 6 and engage with the tooth block 13, thereby driving the movable connecting rod 9 to generate corresponding up and down reciprocating motion, and the limiting sliding sleeve 8 can well support the movable connecting rod 9 while positioning it. When the movable connecting rod 9 moves downward, the connecting seat 15 can be pushed to slide out downward, and the internal optical detector 18 can be pushed to extend to the outside of the protective cover 2, so that the optical detector 18 is closer to the surface of the product to be detected, which shortens the detection distance, improves the detection effect, and facilitates the rapid detection of defects on the product surface.
