[0002] Online lifting visual inspection equipment uses high-precision image acquisition and processing technology to detect various characteristics of products such as size, shape, color, surface defects, etc. The equipment can automatically detect various defects on the product surface, such as cracks, scratches, dents, etc., and mark unqualified products to ensure product quality.

[0003] During the visual inspection process, products of different sizes may need to be inspected, which requires adjusting the spacing to accommodate products of different sizes and ensure that the best imaging effect is obtained every time. In the existing technology, some online lifting visual inspection equipment usually adjusts the distance between the detector and the product by directly controlling the detector to lift and lower it. However, the detector is usually equipped with a variety of precise and complex optical and electronic components. Directly adjusting the height of the detector may cause it to vibrate or shake, and these vibrations are likely to directly affect the image clarity and detection accuracy. Utility Model Content

[0026] Example 1

[0027] Reference Figures 1 to 5 , is an embodiment of the present utility model, which provides an online lifting visual inspection device, which can achieve the effect of keeping the position of the detector 103 unchanged while adjusting the distance between it and the product, which includes:

[0028] The detection mechanism 100 includes a bracket 101, a light source 102 and a detector 103 fixedly mounted on the outer surface of the bracket 101;

[0029] Among them, the bracket 101 is made of aluminum alloy with good thermal conductivity, which can help the detector 103 dissipate heat, thereby extending the service life of the equipment. The light source 102 is used to illuminate the key areas of the product to be inspected to enhance the details in the image, making subtle defects easier to identify. Through proper lighting, the contrast between the target features and the background can be improved, making the image clearer. The detector 103 can detect various features of the product such as size, shape, color, surface defects, etc. through high-precision image acquisition and processing technology, and mark unqualified products. This is an existing technology, and this solution will not be elaborated in detail, and those skilled in the art can clearly understand the working principle.

[0030] The lifting mechanism 200 includes a plurality of legs 201 distributed in a circular array, and a drive assembly 202 disposed on the inner surface of the legs 201;

[0031] It should be noted that the support leg 201 is fixed to the ground by means of lugs and bolts, and the support leg 201 is used to support the various components in the driving assembly 202 .

[0032] It should be noted that the rotating mechanism 300 is provided on the outer surface of the driving assembly 202 .

[0033] Among them, through the cooperation between the various components in the rotating mechanism 300, the angle of the product to be inspected can be adjusted, thereby ensuring the quality of the product.

[0034] Specifically, the drive assembly 202 includes a first servo motor 202a adapted to be mounted on the outer surface of the leg 201, a gear coupling 202b fixedly connected to the top of the leg 201 and used in conjunction with the first servo motor 202a, and a threaded rod 202c fixedly connected to the through end of the gear coupling 202b. The output end of the first servo motor 202a is fixedly connected to the driving end of the gear coupling 202b, and the other end of the gear coupling 202b is fixedly mounted on the inner wall of the leg 201 through a bearing.

[0035] It should be further explained that turning on the first servo motor 202a can drive the driving end of the gear coupling 202b to rotate, so that the through end of the gear coupling 202b drives the threaded rod 202c to rotate.

[0036] Furthermore, the outer surface of the threaded rod 202 c is threadedly connected to the internal thread block 202 d , and the outer surface of the internal thread block 202 d is in sliding contact with the inner surface of the support leg 201 .

[0037] The support legs 201 limit the position of the internal thread block 202d, so that the internal thread block 202d can perform vertical linear motion through the rotation of the threaded rod 202c.

[0038] Preferably, the outer surface of the internal thread block 202d is fixedly connected to the support rod 202e, the top of the support rod 202e is fixedly mounted with a wheel frame 202f, and the inner surface of the wheel frame 202f is fixedly mounted with a positioning wheel 202g via a bearing.

[0039] The internal thread block 202d can drive the support rod 202e, the wheel frame 202f and the positioning wheel 202g to move synchronously while performing the vertical linear motion.

[0040] It should be noted that the driving assembly 202 further includes a slide rail 202h disposed above the positioning wheel 202g, and the outer surface of the positioning wheel 202g is in sliding contact with the inner surface of the slide rail 202h.

[0041] The positioning wheel 202g can not only drive the slide rail 202h to move linearly up and down, but also limit the position of the slide rail 202h, thereby preventing the position of the slide rail 202h from being offset.

[0042] Furthermore, the rotating mechanism 300 includes a second servo motor 301 adapted to be mounted on one side of one of the support rods 202 e , and a spur gear 302 fixedly mounted on an output end of the second servo motor 301 .

[0043] Among them, one of the support rods 202e can drive the second servo motor 301 to move synchronously, so that the second servo motor 301 drives the spur gear 302 to move synchronously, so that the spur gear 302 and the toothed disc 303 always remain engaged. Turning on the second servo motor 301 can drive the gear 302 to rotate synchronously, so that the spur gear 302 drives the toothed disc 303 to rotate.

[0044] Specifically, the rotating mechanism 300 further includes a gear disc 303 meshed with the outer surface of the spur gear 302 and a support platform 304 fixedly connected to the top of the gear disc 303 . The bottom of the gear disc 303 is fixedly connected to the top of the slide rail 202 h.

[0045] The support platform 304 is used to support the product to be inspected, and when the toothed disc 303 rotates, it can drive the support platform 304 and the product to be inspected to rotate synchronously.

[0046] During use, the product to be inspected is placed on top of the support platform 304, and the first servo motor 202a is turned on, so that the output end of the first servo motor 202a drives the driving end of the gear coupling 202b to rotate, and the through end of the gear coupling 202b drives the threaded rod 202c to rotate. The support leg 201 limits the position of the internal thread block 202d, so that the internal thread block 202d can drive the support rod 202e, the wheel frame 202f and the positioning wheel 202g to move synchronously up and down linearly through the rotation of the threaded rod 202c, and the positioning wheel 202g limits the slide rail 202h to prevent the position of the slide rail 202h from shifting.

[0047] By driving the second servo motor 301 to move synchronously through one of the support rods 202e, the second servo motor 301 drives the spur gear 302 to move synchronously, so that the spur gear 302 and the toothed disc 303 always remain in meshing, and the second servo motor 301 is turned on to drive the gear 302 to rotate synchronously, so that the spur gear 302 drives the toothed disc 303 to rotate, and then the toothed disc 303 drives the support platform 304 to rotate synchronously with the product to be tested, so as to achieve the effect of keeping the position of the detector 103 unchanged while adjusting the distance between it and the product.

[0048] In summary, through the cooperation between the elevator 200 and the rotating mechanism 300, the position of the detector 103 is kept unchanged while the distance between it and the product is adjusted. The angle of the product to be inspected can also be adjusted, so that the product can be comprehensively inspected from multiple angles; not only can the vibration or shaking caused by frequent adjustment of the height of the detector 103 be avoided, but the situation of missing defects can also be greatly reduced, thereby improving the detection accuracy.
