[0044] When the embodiment of the present application is actually running, the steps are as follows: Step 1: The product is conveyed and placed on the product seat 330 on the rotating disk 320 by the conveying assembly 200. The product is put into the material pit, and the shooting assembly 400 starts to work. The telecentric camera 440 and the camera 1 430 respectively measure the outer dimensions of the product.

[0045] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages: The product can be placed on the product seat 330 through the conveying component 200, and rotated in turn through the shooting component 400, the pass gauge component 500, and the dotting component 600.

[0046] Example 2 In order to ensure that the product is stably delivered to the rotating disk 320 and improve the flexibility of the device, the present application proposes the following technical solutions for the above technical problems, specifically: See also Figures 8 to 9 The conveying assembly 200 includes a motor 210, a belt 211, a column 212, a motor 220, a belt 221 and a column 222; The motor 1 210 and the motor 2 220 are respectively fixed to the left end of the frame 100, and are used to drive the belt 1 211 and the belt 2 221 to rotate respectively; The first column 212 and the second column 222 are respectively fixed in the middle of the frame 100 in the front and rear; The belt 1 211 and the belt 2 221 are respectively sleeved on the output end of the motor 1 210, the column 1 212 and the output end of the motor 2 20, and the outer side of the column 2 222, and the belt 1 211 and the belt 2 221 both pass through the protective cover 110 and the background plate 120; The belt 1 211 and the belt 2 221 are respectively slidably connected inside the fixed arc plate 1 and the fixed arc plate 2 and are respectively supported in an arc shape by the fixed arc plate 1 and the fixed arc plate 2. The belt 1 211 and the belt 2 221 are arranged in parallel and are used to clamp and convey products.

[0047] A plurality of hook rings 321 are evenly arranged on the rotating disk 320 . The hook rings 321 are semicircular structures and correspond one to one with the product seats 330 . The hook rings 321 are used to hook products from the conveying assembly 200 and place them on the product seats 330 .

[0048] like Fig.11 As shown, it is a schematic diagram of the state of belt 1 211 and belt 2 221 of the present application when clamping and conveying a product. The solid arrows in the figure represent their respective rotation directions. Belt 1 211 and belt 2 221 rotate in opposite directions, and can clamp and convey the product to the position of the rotating disk 320.

[0049] The present application can realize a continuous and stable conveying process through the operation of belt 1 211 and belt 2 221 and the clamping action therebetween, avoiding the discontinuity and instability of manual loading, thereby improving the conveying efficiency. At the same time, it improves the conveying efficiency and positioning accuracy, reduces labor costs and safety risks, and further optimizes the spatial layout and enhances the flexibility of the production line.

[0050] Example 3 Considering that only one-side photography can be performed when the product is transported to the conveying assembly 200, the photography surface is single, there is a blind spot for measurement, and 360° all-round photography and detection cannot be achieved, resulting in inaccurate measurement results. In view of the above technical problems, the present application proposes the following technical solutions, specifically: See also Figures 9 and 10 A plurality of clamping rings 230 are evenly fixed on the outer side of the belt 221, and the clamping ring 230 is a semicircular ring structure for clamping the product; The clamping ring 230 includes a telescopic rod 231, an arc plate 232 and a roller 233; The telescopic rod 231 is fixed on the outside of the belt 221; the arc plate 232 is fixed on the telescopic end of the telescopic rod 231; the inner wall of the arc plate 232 is rotatably connected to a plurality of rollers 233, the rollers 233 are evenly arranged along the circumference of the arc plate 232, and the rollers 233 are in contact with the product.

[0051] In this embodiment, by providing a clamping ring 230 and a roller 233, the product can be conveyed in a rotational manner (that is, the product can rotate during the conveying process) under the joint action of the belt 211, the clamping ring 230 and the roller 233, so that the product can be photographed from all directions when it is conveyed to the shooting position to avoid measurement blind spots. The multi-directional shooting method can capture the appearance characteristics of the product more comprehensively and improve the accuracy and comprehensiveness of the detection. At the same time, the design of the clamping ring 230 and the roller 233 enables the equipment to adapt to products of different shapes and sizes. Since the product can rotate, no matter what its shape is, it can be ensured that each part is fully photographed, thereby enhancing the versatility and adaptability of the equipment and making the equipment suitable for the detection of a variety of products.

[0052] Example 4 Considering that before the product is hooked out by the hook ring 321, the product may be pre-detached from the belt 1 211 and the belt 2 221 (i.e., the clamping ring 230) when it moves to the hooking position, which may cause the product to shift in position, so that the hook ring 321 cannot bring the product out in time or the product cannot be accurately placed in the product seat 330, the application proposes the following technical solutions to the above technical problems, specifically: See also Figure 11 to Figure 12 A plurality of flexible plates 1 240 and flexible plates 2 250 are evenly fixed on the inner sides of the belt 1 211 and the belt 2 221, respectively. The flexible plates 1 240 correspond one-to-one to the clamping ring 230, and the flexible plates 2 250 are used to cooperate with the flexible plates 1 240 so that the product will not be displaced.

[0053] The present application sets the flexible plate 1 240 and the flexible plate 250 so that before and when the product is hooked out by the hook ring 321, the flexible plate 1 240 and the flexible plate 2 250 can make the belt 1 211 and the belt 2 221 slightly deviate when the hook ring 321 hooks out the product. Fig.12 As shown, the solid arrows represent the offset directions of the two belts, and the hollow arrows represent the rotation direction of the rotating disk 320). This offset is in the same direction as the rotating disk 320, thereby compensating for the position offset of the product that may be caused by inertia or insufficient friction, ensuring that the product can be smoothly and accurately brought out from the belt 1 211 and the belt 2 221 by the hook 321 and smoothly placed on the product seat 330, so that the product can be smoothly transported to the product seat 330.

[0054] Example 5 In order to enable the product to fall into the product seat 330 accurately and precisely and prevent the product from being skewed or misaligned, the present application proposes the following technical solutions to the above technical problems, specifically: See also Figures 12 to 16A rubber sleeve 340 is fixed on the product seat 330 for positioning the product and preventing the product from being damaged; the rubber sleeve 340 is an annular structure and its interior is a conical inclined surface structure, including a conical iron sheet 341 and a fixing block 342; The conical iron sheets 341 are provided in multiple groups, arranged up and down, and the radial size of each group of conical iron sheets 341 decreases from bottom to top. Each group of conical iron sheets 341 is formed by stacking multiple conical iron sheets 341 to adapt to products of different sizes. The fixing block 342 is a cone structure with a through-hole structure in the middle. It is placed upside down and fixed to the bottom of the rubber sleeve 340 in a detachable manner to fix the bottom of the product.

[0055] This embodiment effectively solves the problem of product displacement and inaccurate positioning during transportation by providing a rubber sleeve 340. The rubber sleeve 340 provides a buffering effect to ensure the stability of the product during transportation. The inner diameter of the rubber sleeve 340 can be controlled by controlling the number of inserted conical iron sheets 341, so that it is suitable for positioning products of different sizes. At the same time, the conical iron sheets 341 arranged up and down can form an inclined surface with a small gradient, which has a guiding effect on the product falling into the rubber sleeve 340. At the same time, the cylindrical structure in the fixed block 342 can fit the side wall of the product, thereby realizing precise positioning of the product, improving the accuracy and efficiency of detection, reducing detection errors caused by product displacement or inaccurate positioning, and improving the overall detection quality.

[0056] It should be noted that in the above embodiments, the description of each embodiment has its own emphasis, and for parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0057] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
