[0034] Embodiment 1 of the precision detection fixture of the present utility model

[0035] Please refer to Figures 1-5 , the precision detection fixture of the present utility model includes: a bottom mold 1 for placing the product to be tested and a frame-shaped panel 202 that can cover the product. The design dimensions of the frame-shaped panel 202 match the dimensions of the optical film on the product to be tested, so as to compare the dimensions of the optical film after covering the frame-shaped panel 202. The present application realizes the rapid determination of the assembly precision of the product main body and the optical film through ingenious design. Specifically, the fixture uses the positioning of the product main body and the design dimensions of the frame-shaped panel 202 for positioning.

[0037] Furthermore, a connecting member is provided between the bottom mold 1 and the frame-shaped panel 202. The connecting member is used to realize the connection between the bottom mold 1 and the frame-shaped panel 202 and enables the frame-shaped panel 202 to rotate and open / close, which greatly facilitates the operation. When workers place and remove products, they do not need to perform cumbersome disassembly and installation steps. They only need to easily rotate the frame-shaped panel 202 to complete the operation, significantly improving work efficiency.

[0038] Furthermore, as Figure 1 and Figure 2 shown, the connecting member includes two connection seats 3 fixedly installed on the top of the bottom mold 1. A connecting shaft 301 is connected between the two connection seats 3. The two connection seats 3 cooperate with each other to support the connecting shaft 301, ensuring the stability of the connection. Even during frequent opening and closing operations, the frame-shaped panel 202 will not shake or shift, thus always ensuring the accuracy and consistency of inspections. This stable connection method can also significantly reduce the probability of failures caused by loose components or unstable connections, lower the maintenance cost and the production downtime caused by equipment failures, and provide strong guarantee for the continuous and stable progress of production.

[0039] Furthermore, as Figure 1 and Figure 2As shown in the figure, a cross block 201 is sleeved on the outer surface of the connecting shaft 301. The cross block 201 is connected to the frame-shaped panel 202. The mutual cooperation of the connecting seat 3, the connecting shaft 301 and the cross block 201 can realize the connection between the frame-shaped panel 202 and the bottom mold 1. Moreover, the cross block 201 can rotate around the connecting shaft 301, thereby realizing the rotary opening and closing of the frame-shaped panel 202, improving the convenience of operation. During frequent detection processes, the opening and closing actions can be quickly completed, saving time. Moreover, this mechanical structure is relatively simple, not prone to failure, and reduces the maintenance cost.

[0040] Furthermore, as Figure 3 shown, a positioning groove 203 is formed on the cross block 201, and the inner wall of the positioning groove 203 is inserted into the frame-shaped panel 202. The cross block 201 and the frame-shaped panel 202 are connected by bolts. The setting of the positioning groove 203 can facilitate the alignment of the cross block 201 and the frame-shaped panel 202 during installation. During the assembly process, workers can quickly and accurately align the two, not only significantly improving the assembly efficiency, but also greatly reducing the possible errors during the assembly process, ensuring the accuracy and stability of the jig. The bolt connection provides a firm and reliable connection method, so that the frame-shaped panel 202 will not loosen due to vibration or external force during use, and always maintains good detection accuracy, providing a strong guarantee for the stability of product quality.

[0041] Embodiment II of the precision detection jig of the present utility model

[0042] Furthermore, in the precision detection jig of the present utility model, a positioning member is arranged on the bottom mold 1. The positioning member is used for positioning the product to be measured. The positioning member can ensure the accurate position of the product to be measured on the bottom mold 1, avoiding detection errors caused by improper placement of the product. Accurate positioning helps to improve the consistency and repeatability of detection, making each detection result more reliable;

[0043] The setting of the positioning member plays a key role in ensuring the accurate position of the product to be measured on the bottom mold 1. Through precise positioning, detection errors caused by inaccurate placement positions of the product are avoided, thereby improving the accuracy and reliability of the detection results. This precise positioning helps to achieve the consistency and repeatability of detection. No matter who the operator is and when the detection is carried out, highly consistent detection results can be obtained, enabling more stable control of product quality.

[0044] Furthermore, as Figure 2 shown, the positioning member includes a plurality of positioning blocks 6. The plurality of positioning blocks 6 are all fixedly installed on the top of the bottom mold 1. The plurality of positioning blocks 6 form an area for placing the product to be measured on the top of the bottom mold 1, so that the product to be measured will not shift after being placed, thus ensuring the accuracy of detection.

[0045] Embodiment III of the precision detection jig of the present utility model

[0046] Furthermore, as shown in Figure 2 , on both sides of the top of the bottom mold 1, placing and removing grooves 5 are provided. The provision of the placing and removing grooves 5 facilitates the placing and removing of the product to be measured. The provision of the placing and removing grooves 5 provides great convenience for workers to pick up and place the product to be measured. In a large-scale production environment, workers need to operate frequently. The placing and removing grooves 5 can significantly reduce the operation time and improve work efficiency. Each placing and removing action can be more rapid and accurate, thereby accelerating the speed of the entire production process. This is of great significance for increasing production and meeting market demand. Especially during the production peak period, it can effectively handle a large number of detection tasks and ensure that the production progress is not affected.

[0047] Furthermore, as shown in Figure 2 , a notch 4 is further provided on the top of the bottom mold 1. The notch 4 is located on the side of the bottom mold 1 away from the connecting shaft 301. The provision of the notch 4 facilitates the opening of the frame-shaped panel 202, reducing the operation difficulty and fatigue. For workers who need to perform detection operations for a long time, this can significantly improve work comfort and efficiency and reduce mistakes and errors caused by operation fatigue.

[0048] Furthermore, as shown in Figure 4 , a plurality of cushion feet 101 are installed at the bottom of the bottom mold 1. The cushion feet 101 are used for supporting the bottom mold 1, effectively keeping the bottom mold 1 in a stable horizontal state. During the operation process, whether it is affected by slight external vibrations or the tiny impact forces generated during the detection process, the bottom mold 1 can remain stable, thereby avoiding adverse effects on the detection results due to the shaking of the bottom mold 1. At the same time, the cushion feet 101 can also play a good shock-absorbing role, absorbing and buffering the external vibration energy and reducing the interference of external vibrations on the detection to ensure the accuracy and reliability of the detection results.

[0049] During use, open the frame-shaped panel 202, place the product with the optical film attached on the top of the bottom mold 1, then cover the frame-shaped panel 202, and compare the size of the optical film on the product surface to determine whether the assembly accuracy of the optical film is qualified.
