[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] ReferenceFigures 1 - 3 , an embodiment provided by the present utility model: a product appearance vision detection device, including a frame 1, a detection lens 3 is fixedly connected to the outer wall of the top of the frame 1, and a driving machine 31 is fixedly connected to the outer wall of one side of the frame 1. By setting the driving machine 31 to drive the rotating rod 43 to rotate and start and stop, the turning angle of the annular frame 42 is adjusted. An adjusting mechanism 4 is arranged on the driving machine 31, an auxiliary mechanism 5 is arranged on the adjusting mechanism 4, a bearing frame 41 is arranged on the adjusting mechanism 4, the bearing frame 41 is fixedly connected to the outer wall of one side of the driving machine 31, and the outer wall of the side of the bearing frame 41 away from the driving machine 31 is rotatably connected to an annular frame 42 through a bearing. The annular frame 42 is fixedly connected to the rotating rod 43, the output end of the driving machine 31 is fixedly connected to the rotating rod 43 through a coupling, a first bevel gear 44 is fixedly connected to the rotating rod 43, and a second bevel gear 441 is meshed with the first bevel gear 44. The inner ring of the second bevel gear 441 is fixedly connected to a straight rod 442, and a rolling disc 45 is fixedly connected to the straight rod 442. By setting the rolling disc 45 to rotate to drive the movable frame 46 to adjust the rotation angle, the movable frame 46 is rollingly connected to the rolling disc 45, and a clamp frame 47 is fixedly connected to the inner wall of the side of the movable frame 46. By setting the clamp frame 47, the product to be detected is clamped and fixed.

[0025] Refer to Figures 2 - 3 , the rotating rod 43 penetrates the inner wall of one side of the annular frame 42, and the rotating rod 43 is rotatably connected to the outer wall of one side of the annular frame 42 through a bearing. The two ends of the straight rod 442 are rotatably connected to the inner walls of both sides of the annular frame 42 through bearings, and the movable frame 46 is rotatably connected to the inner wall of one side of the annular frame 42 through a bearing. A grinding pad is fixedly connected to the outer wall of the side of the movable frame 46. By setting the grinding pad, the rolling friction between the movable frame 46 and the rolling disc 45 is increased, preventing the problem of slipping between the movable frame 46 and the rolling disc 45 when the movable frame 46 rotates. An operation panel 2 is fixedly connected to the outer wall of one side of the frame 1. By setting the operation panel 2, the driving machine 31 is controlled to start and stop.

[0026] Refer to Figures 3 - 4, the auxiliary mechanism 5 includes a paddle 51. The paddle 51 is slidably connected to the inner walls on both sides of the fixture frame 47. A clamping tooth 52 is fixedly connected to the outer wall at the bottom of the paddle 51. An arc-shaped tooth 53 is hinged to the outer wall on one side of the clamping tooth 52. By setting the arc-shaped tooth 53, the angle can be adjusted according to the different concave and convex surfaces of the product to be detected for clamping, reducing the problem that the middle gap is relatively large when the fixed clamping head is clamped, which is likely to cause insufficient friction between the clamps and result in loosening and falling off. A telescopic spring 54 is fixedly connected to the outer wall on one side of the paddle 51. By setting the paddle 51, it is convenient for personnel to drag and operate. An indication mark is provided on the outer wall on one side of the paddle 51. There are several arc-shaped teeth 53, and several arc-shaped teeth 53 are symmetrically hinged to the outer wall on the side of the clamping tooth 52 respectively. The end of the telescopic spring 54 away from the paddle 51 is fixedly connected to the inner wall on one side of the fixture frame 47. By setting the telescopic spring 54, a continuous thrust is generated on the arc-shaped tooth 53 to prevent jitter from easily occurring when the product rotates and adjusts the angle, and to prevent loosening and falling off during rigid clamping.

[0027] Working principle: By starting the driving machine 31, the rotating rod 43 rotates. The rotation of the rotating rod 43 drives the annular frame 42 to rotate, adjusting the angle of the product on the fixture frame 47 so that the detection lens 3 can perform real-time detection. At the same time, the rotation of the rotating rod 43 drives the first bevel gear 44 to rotate. The rotation of the first bevel gear 44 drives the second bevel gear 441 to rotate. The rotation of the second bevel gear 441 drives the straight rod 442 to rotate. The rotation of the straight rod 442 drives the roller disc 45 to rotate. The rotation of the roller disc 45 drives the movable frame 46 to rotate. The rotation of the movable frame 46 drives the product on the fixture frame 47 to perform a lateral angle adjustment, enabling the detection lens 3 to detect the side of the product while detecting the angle. After the detection is completed, by pulling the paddle 51 and the telescopic spring 54, the clamping tooth 52 is moved to adjust the movement of the arc-shaped tooth 53 away from the product, facilitating the removal and replacement of a new product to be detected. For the outer surface shapes of different products to be detected, place them on the arc-shaped tooth 53 and then release the paddle 51, so that the arc-shaped tooth 53 adjusts the angle according to the concave and convex shape of the outer surface of the product for clamping.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
