An elastic gasket is provided on the support block, and the flip mechanism 2 is supported in the parts assembly state by the support block.

[0082] And / or, a flip-in-place self-locking component 17 is also provided on the flip bracket 201 or the second movable plate 402, and the flip-in-place self-locking component 17 includes a second fixed block 1701, and the second fixed block 1701 is installed on the flip bracket 201 or the second movable plate 402. A second self-locking member 1702 is movably installed on the second fixed block 1701, and a third elastic member 1703 is provided between the second self-locking member 1702 and the second fixed block 1701. The third elastic member 1703 is preferably a spring, and a snap structure is provided on the second self-locking member 1702. When the flip plate 202 is flipped into place, the snap of the second self-locking member 1702 will lock the flip plate 202, thereby realizing the self-locking fixation of the flip plate 202 when it is flipped into place, and the operation is simple.

[0083] Combination Figure 1-Figure 4 As shown, the part positioning mechanism 1 includes a connecting arm 101 connected to the flip connecting rod 203, and the end of the connecting arm 101 away from the flip connecting rod 203 is connected to a mounting plate 102, and a placement groove 103 for placing the part is provided on the mounting plate 102. The placement groove 103 adopts a contoured structure adapted to the shape of the part, and a plurality of suction cups 104 are provided in the placement groove 103. The suction cups 104 can absorb the part and fix it in the vertical direction to prevent it from falling off during the flipping process. A clamping member for clamping the part is movably installed on one side of the mounting plate 102. 105, the clamping member 105 is rotatably mounted on the mounting plate 102, and a fourth elastic member 106 is provided between the clamping member 105 and the mounting plate 102. The fourth elastic member 106 is preferably a spring. The end of the clamping member 105 that contacts the part is arranged at a right angle, and gaskets are arranged on the inner side of the right-angle structure, which can apply force to the two sides of the part to make the part close to one side of the placement groove 103, thereby achieving horizontal clamping of the part. In addition, the assembled parts can be released by rotating the clamping member 105 and compressing the fourth elastic member 106.

[0084] In addition, in order to ensure the structural accuracy requirements and the precision requirements of movement, the device adopts a large number of guide and limit mechanisms such as slide rails, sliders, guide rods, guide sleeves, etc. in the structure. Such guide and limit mechanisms are common in daily life, are very easy to purchase on the market, and are common knowledge to technicians in this technical field. They will not be repeated here and are not marked in detail in the figure.

[0085] Combination Figure 1-Figure 3 As shown, an AOI assembly equipment includes a positioning adjustment device.

[0086] For ease of understanding, the working process of this embodiment is given below:

[0087] Combination Figure 1-Figure 11 As shown, first, the part is placed in the placement groove 103 of the mounting plate 102, and the part is clamped and positioned by the clamping member 105, and at the same time, the part is adsorbed by the suction cup 104, and then the flipping mechanism 2 is pushed to flip by the flip handle 204. When the flipping mechanism 2 is about to flip into place, the buffer component 16 buffers it. When it is flipped into place, the magnetic member 302 provided on the flip plate 202 senses the sensor 301, and the sensor 301 issues a prompt that the next action can be performed. At the same time, the flipping into place self-locking component 17 self-locks and fixes the flipping mechanism 2;

[0088] Afterwards, the second movable plate 402 is pressed down by moving the handle 403, and the second movable plate 402 moves downward along the second movable guide assembly 11. When it moves to the limit adjustment member 12 and abuts against the second bottom plate 401, the in-place self-locking assembly 5 realizes self-locking fixation of the second movable plate 402. When the parts are assembled, the in-place self-locking assembly 5 is unlocked. Under the action of the reset member 404, the second movable plate 402 moves upward and moves to the highest position of the limit limit assembly 13, and is ready for the next operation. After use, the mobile fool-proofing assembly 14 is inserted between the second movable plate 402 and the second bottom plate 401 for mobile fool-proofing to avoid illegal operation by operators and damage to the device.

[0089] When the second movable plate 402 of the up-and-down moving mechanism 4 is self-lockingly fixed with the second bottom plate 401, the position of the part in the X and Y directions is adjusted by the XY adjustment mechanism 6. Then, the position of the part in the Z direction is fine-tuned by the adjustment rod 703 and the adjustment member 702 of the Z-direction moving adjustment mechanism 7, thereby realizing the movement and adjustment of the part in multiple directions, which facilitates the rapid alignment and assembly of the parts.

[0090] In summary, the present invention provides a positioning adjustment device and AOI assembly equipment, which can be adjusted and moved in multiple directions, have a precise and reliable structure, can quickly complete the positioning assembly, and improve assembly efficiency.

[0091] It should be understood that the purpose of these embodiments is only to illustrate the present invention and is not intended to limit the protection scope of the present invention. In addition, it should also be understood that after reading the technical content of the present invention, those skilled in the art can make various changes, modifications and / or variations to the present invention, and all of these equivalent forms also fall within the protection scope defined by the appended claims of this application.
