DETAILED DESCRIPTION

[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] The utility model provides Figure 1-3 A small visual inspection machine shown includes a fixing plate a1 and a fixing plate b4 installed on the left side of the fixing plate a1;

[0025] A conveyor belt 3 is provided between the fixed plate a1 and the fixed plate b4 to convey the products to be inspected;

[0026] A camera 5 is provided on the upper side of the conveyor belt 3 to photograph the products on the conveyor belt 3. When visual inspection of the products is performed, the products to be inspected are transported to the lower side of the camera 5 through the conveyor belt 3, and the surface of the products is photographed by the camera 5 to identify the products. The photographed pictures are compared with the standard products of the system, so that the defective products can be removed from the conveyor belt 3 under the inspection intervention of the staff;

[0027] Two guide plates a2 are symmetrically arranged on the conveyor belt 3, and the rear end outer walls of the two guide plates a2 are fixedly connected with guide plates b17, and the rear end outer walls of the two guide plates b17 are fixedly connected with guide plates c18. When transporting on the conveyor belt 3, the products located on the left and right sides of the conveyor belt 3 can be guided to the center of the conveyor belt by the guidance of the guide plates a2, b17 and c18.

[0028] like Figure 2As shown, the upper outer walls of the fixed plate a1 and the fixed plate b4 are fixedly connected with a fixed block a16, the upper outer walls of the fixed plate a1 and the fixed plate b4 and the rear side of the fixed block a16 are fixedly connected with a fixed block b20, a connecting plate b24 is arranged between the right end outer walls of the two guide plates a2 and the fixed block a16, and a connecting plate a19 is arranged between the two guide plates c18 and the fixed block b20 to maintain the distance between the guide plate a2 and the guide plate c18 and the conveyor belt 3.

[0029] The positions of guide plates a2, b17 and c18 are controlled by connecting plates a19 and b24 inside fixed blocks a16 and b20 to limit the distance between guide plates a2, b17 and c18 and the conveyor belt 3, thereby preventing the conveyor belt 3 from contacting guide plates a2, b17 and c18 when moving.

[0030] like Figure 2 and Figure 3 As shown, the upper outer walls of the connecting plates a19 and b24 are equidistantly provided with a plurality of threaded holes a22 that penetrate upward and downward, the upper outer walls of the fixing blocks a16 and b20 are provided with threaded holes b23 that open upward, and the upper outer walls of the fixing blocks a16 and b20 are provided with fixing screws 21 that penetrate downward into the threaded holes a22 and b23 to threadably fix the connecting plates b24 and a19 with the fixing blocks a16 and b20, and the two guide plates b17 are symmetrically inclined inward.

[0031] When adjusting the spacing between the two guide plates a2, the guide plate b17 and the guide plate c18, first unscrew the fixing screw 21 to adjust the spacing between the two guide plates a2, the guide plate b17 and the guide plate c18. After the spacing adjustment is completed, insert the fixing screw 21 downward into the fixing block a16 and the fixing block b20, and pass through the threaded hole a22 on the connecting plate a19 and the connecting plate b24, and then screw it into the threaded hole b23 inside the fixing block a16 and the fixing block b20 to complete the fixation of the guide plate a2, the guide plate b17 and the guide plate c18.

[0032] like Figure 1 As shown, the upper outer walls of the fixed plates a1 and b4 are both fixedly connected with columns 15. A crossbeam 13 is fixedly connected between the two columns 15, and a support plate 12 is fixedly connected to the rear end outer wall of the crossbeam 13. An upwardly open chute b8 is provided inside the upper outer wall of the crossbeam 13, and a fixed end 10 is transmission-connected inside the chute b8. A conveying crawler 11 is fixedly connected between the fixed end 10 and the support plate 12.

[0033] The fixed end 10 can be moved laterally inside the slide groove b8 to drive the camera 5 to move laterally to the stopping position of the product on the conveyor belt 3.

[0034] like Figure 1 As shown, the front end outer wall of the fixed end 10 is fixedly connected to the fixing frame 9, the front end outer wall of the fixing frame 9 is transmission-connected to the driver 6 to drive the camera 5 to move up and down, a slide groove a7 is opened inside the front end outer wall of the fixing frame 9 to limit the moving range of the driver 6, and the right end outer wall of the driver 6 is fixedly connected to the searchlight 14 to shine light on the product.

[0035] The camera 5 can also be moved up and down in the slide groove a7 inside the fixed frame 9 through the driver 6 to control the camera 5 to shoot pictures of different sizes to adapt to the areas of different products. When shooting products, the searchlight 14 can be used to shine light on the products to increase the clarity of the camera 5 when shooting.

[0036] The implementation principle of this embodiment is as follows: when visually inspecting the product, the product to be inspected is placed on the conveyor belt 3, which drives the product to move and guides the product to the center of the conveyor belt 3 under the constraints of the guide plates a2, b17 and c18. When the product moves to the lower side of the camera 5, the conveyor belt 3 stops moving, and the camera 5 moves up and down under the drive of the driver 6, adjusts the size of the captured image, and moves to the top of the center of the product under the lateral movement of the fixed end 10, and then shoots, and supplements the light with the searchlight 14. The captured product image will be transmitted to the screen for inspection by the staff and compared with the standard product. When the comparison difference is large, the staff will remove the defective product.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
