[0039] Please adopt Figure 1 and Figure 3The X-direction linear shift module 7 includes an X-direction linear sliding assembly 71 and a sliding plate 72 mounted on the X-direction linear sliding assembly 71. The sliding plate 72 moves back and forth in the X-direction through the X-direction linear sliding assembly 71 to achieve switching between the loading station, the inspection station, and the unloading station.

[0040] Please adopt Figure 1 and Figure 3 The Y-direction offset structure 8 is mounted on the sliding plate 72 and moves back and forth in the X-direction along with the sliding plate 72. The mounting frame 1 is mounted on the Y-direction offset structure, which enables the mounting frame 1 to move back and forth in the Y-direction to adjust the position of the flexible positioning carrier 3, facilitate staggered loading or unloading, and improve work efficiency.

[0041] Please refer to Figure 1 The protective housing 9 covers the flexible positioning carrier 3, the X-direction opening mechanism 4, the Y-direction opening mechanism 5 and the rotating mechanism 6 to provide protection. The protective housing 9 has a window 91 through which the acupuncture point 311 is exposed.

[0042] Please continue to participate Figures 1 to 11 The working process of AOI inspection flexible positioning tool 100 is as follows:

[0043] The flexible positioning carrier 3 is positioned at the loading station under the operation of the X-direction linear shift module 7 and the Y-direction offset structure 8. The first driving member 42 of the X-direction opening mechanism 4 drives the first supporting member 43 to cause the five first pressing members 41 to move along the Y-direction. The first pressing members 41 penetrate into the first slot 312, and the first guide bevel 411 presses inwardly against the lower end of the first pressing claw 32, causing the first pressing claw 32 to open in the X-direction from the first rotating shaft 34. The second driving member 52 of the Y-direction opening mechanism 5 drives the second supporting member 53 to cause the five second pressing members 51 to move along the X-direction. The second pressing members 51 penetrate into the second slot 313, and the second guide bevel 511 presses inwardly against the lower end of the second pressing claw 33, causing the second pressing claw 33 to open in the Y-direction from the second rotating shaft 35. The X-direction opening mechanism 4 and the Y-direction opening mechanism 5 operate simultaneously or continuously.

[0044] After the first and second pressing jaws 32 and 33 are opened, the five products S to be tested are placed into the corresponding five acupuncture points. The X-direction opening mechanism 4 and the Y-direction opening mechanism 5 operate again, the first pressing body 41 moves out of the first slot 312, and the second pressing body 5 moves out of the second slot 313. The first pressing jaw 32, under the action of the first elastic member, returns to its original position and presses against the product S to be tested. The second pressing jaw 33, under the action of the second elastic member, returns to its original position and presses against the product S to be tested, thus achieving the positioning of the product to be tested.

[0045] The X-direction linear displacement module 7 and the Y-direction offset structure 8 operate again to move the flexible positioning carrier 3 to the inspection station after the inspection is completed. During the movement to the unloading station or after arriving at the unloading station, the X-direction opening mechanism 4 and the Y-direction opening mechanism 5 open the first and second pressing jaws 32 and 33 to allow unloading.

[0046] The rotating mechanism 6 is used to rotate the flexible positioning carrier 3, and the rotating drive 62 drives all the rotating shafts 61 to rotate synchronously from 0 to 90 degrees so that the acupuncture points and products can adapt to the loading position, unloading position or tray position, etc., thereby improving adaptability and working efficiency.

[0047] The Y-direction dislocation structure 8 is used to adjust the position in the Y-direction to adapt to loading, testing, unloading, adapt to the working environment, and improve work efficiency.

[0048] The AOI inspection flexible positioning tool 100 has at least the following advantages:

[0049] Advantage 1: Five flexible positioning carriers 3 are arranged side by side, which can realize mechanical batch loading and unloading and improve work efficiency;

[0050] Advantage 2: Avoid mixing products with different acupoint numbers and causing product damage;

[0051] Advantage 3: Through the flexible positioning carrier 3, X-direction opening mechanism 4 and Y-direction opening mechanism 5, accurate positioning of different products is achieved, product deviation is avoided, and detection accuracy and efficiency are improved;

[0052] Advantage 4: The flexible positioning carrier 3 has small structural limitations, is highly tolerant of product dimensions, and has strong versatility as a whole.

[0053] Advantage 5: The rotating mechanism can adjust the acupuncture point angle, which is convenient for loading and unloading, streamlining the mechanism and improving efficiency.

[0054] The present utility model also discloses an AOI inspection device with an AOI inspection flexible positioning tool 100, which improves inspection accuracy and efficiency.
