[0043] A loading and unloading part, which has a translation assembly 5 and a lifting assembly 6. The translation assembly 5 is installed on the base 1, the lifting assembly 6 is installed above the translation assembly 5, and a plurality of products to be measured are placed on the lifting assembly 6. Through the cooperation of the lifting assembly 5 and the translation assembly 6, the products to be measured enter the clamping positions of the clamping assemblies 3.

[0044] This embodiment adopts an industrial design concept and has a perfect process connection mechanism; through the modular design of the measuring part / fixture part / loading and unloading part, the multi-functional integration of measurement → clamping → transportation is realized; the rotation assembly and the positioning assembly cooperate to realize multi-angle measurement of multiple products, and the lifting / translation assembly realizes automatic loading and unloading.

[0045] In a specific example, the rotating assembly 2 includes two brackets 21, a driving motor 22, and ten frames 23 connected side by side. The two brackets 21 are installed on the base 1 at intervals. A driving motor 22 is installed on one of the brackets 21. The driving end of the driving motor 22 is connected to a frame 23 through a clamping assembly 3, and the two frames 23 are connected and fixed through the clamping assembly 3.

[0046] The double-bracket support structure in this embodiment enhances the rotational stability and prevents jitter during high-speed rotation; the ten-frame parallel design enables batch clamping, greatly improving the measurement efficiency; the direct connection structure of the driving motor simplifies the transmission system and reduces the failure rate.

The second electric push rod 43 is used to drive the limit pin 44 to expand and contract, and the limit pin 44 corresponds to and matches the limit groove.

[0050] In this embodiment, the cooperation between the limit pin and the notch realizes mechanical hard limit, and the electric push rod drives double positioning (rotation drive + pin-slot locking) to achieve automation.

[0051] In a specific example, four limit grooves are provided on the positioning disk 41, corresponding to 90, 180, 270, and 360 degrees respectively, for limiting the rotation angle of the frame 23.

[0057] Embodiment 2

[0058] To achieve the above object, this embodiment also provides a usage method of a multi-angle fixture for a measuring device, including the following steps:

[0059] S1. Batch clamping and translation of products: Drive the lifting component 6 to move back and forth through the third electric push rod 51 in the translation component 5. When the lifting component 6 is in front of the fixture part, place the products in batches on the support plate 64, and move the products on the support plate 64 to the lower part of the clamping component 3 through the translation component 5;

[0060] S2. Lifting operation of products: When the products move to the lower part of the clamping component 3, drive the products to rise through the fourth electric push rod 61 in the lifting component 6, move the support plate 64 and the products upward, and pass through the frame 23 until they move to the clamping position of the clamping component 3;

[0061] S3. Clamping operation of products: Push the movable plate 32 and the U-shaped plate 33 to move through the first electric push rod 36 to clamp the products;

[0062] S4. Reset operation: When the products are clamped, reset the lifting component 6 and the translation component 5 in sequence. The purpose of this is to avoid light leakage during subsequent measurement;

[0063] S5. Measuring and holding operation of products: Measure the products through the measuring camera 12;

[0064] S6, product flipping operation: when it is necessary to measure different angles of the product, the frame 23 connected to the product is driven by the driving motor 22 to rotate to meet the needs of measuring different angles of the product;

[0065] S7, limit operation: when the product is rotated to a specified angle, the second electric push rod 43 and the limit pin 44 in the positioning assembly 4 cooperate to limit the product within a range of 90, 180, 270 or 360 degrees, ensuring the accuracy of the product when measuring different angles;

[0066] S8, unloading and loading operations: After the product measurement is completed, the product is reset to the initial angle, and then the translation component 5 and the lifting component 6 are operated to move the support plate 64 to the position of the product after the measurement is completed. The product is released through the clamping component 3 and supported by the support plate 64. The translation component 5 and the lifting component 6 are operated again to move the measured product to the front of the clamping part, remove the measured products on the support plate 64, and place the next batch of products to be measured, and then repeat the operation process of S1 to S8.

[0067] It should be noted that unreset components may block the measurement path or form gaps with the fixture, causing external stray light to enter the measurement area and interfere with the imaging accuracy of the camera. Therefore, after the product is clamped, resetting the lifting component and the translation component in sequence can avoid light leakage. This embodiment realizes full-process automated operation and reduces manual intervention by 80%. The original "clamping-measurement-reset" cycle process test cycle is greatly shortened. The anti-light leakage design improves the measurement accuracy. The batch processing capability supports continuous operation.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
