[0002] In the manufacturing process of special optical glass, precise coating is usually required on both front and back surfaces to endow the glass with specific optical properties. The existing coating clamps are mostly single-function, and after coating one surface of the glass, the glass needs to be manually or with the help of external equipment taken out of the clamp, turned over and repositioned for coating the other surface. This operation mode has significant drawbacks: firstly, the secondary clamping is not only inefficient, but also seriously restricts production efficiency, and the positioning reference changes easily lead to poor alignment accuracy of the two surface coatings, and even the glass surface or the coated film is scratched due to improper operation, resulting in a decrease in product yield.

The lifting mechanism 8 comprises a rotating shaft 801 connected to the fixed ring 705 through a bearing, and the rotating shaft 801 is symmetrically fixed with a gear 802 and a swing rod 803 in front and back, and the two swing rods 803 are fixed with a roller 804 therebetween, the roller 804 contacts the glass body 9 to realize the lifting action, and the rotating shaft 801 rotates an angle of 90°-120° each time; the swing rod 803 is further fixed with a positioning rod 805, and the positioning rod 805 is slidably connected with an inclined block 806, and the inclined block 806 is symmetrically fixed on the mounting plate 603 in up and down;

The self-locking mechanism 7 comprises side plates 701 fixed symmetrically on the vertical plate 601, top rods 702 slidably connected to the side plates 701, and clamping tooth plates 703 fixed to one end of the top rods 702 close to the limiting tooth plate 602, which cooperate with the limiting tooth plate 602 to realize locking effect; one end of the top rods 702 is fixedly connected to the second springs 704, the other end of the second springs 704 is fixed to the side plates 701, and the second springs 704 are symmetrically distributed above and below the center line of the vertical plate 601; the top rods 702 are slidably connected to the fixed rings 705, the fixed rings 705 are symmetrically provided with inclined grooves 706 on the inner side, and the inclined grooves 706 are slidably connected to the top rods 702; one end of the fixed rings 705 is fixedly connected to the round rods 707, and the other end of the round rods 707 is fixed to the fixed plate 4; After the glass body 9 is clamped and fixed, as shown in FIG. 8, the clamping plate 608 and the rubber pad 609 can realize the clamping and fixing of the glass body 9, and at this time the swing rod 803 and the supporting roller 804 are in the state of 90°-120° relative to the glass body 9, so as to realize the active avoidance of the swing rod 803 and the supporting roller 804 in the process of subsequent glass body 9 overturning; Figures 1-7As shown, when the glass body 9 is turned over, only the motor 5 is controlled to drive the vertical plate 601 to rotate 180°, so as to drive the mounting plate 603, the clamping plate 608, the rubber pad 609 and the glass body 9 to rotate 180°, and due to the rotation avoidance of the swing rod 803 and the supporting roller 804, the normal turning over of the glass body 9 can be ensured. When the vertical plate 601 rotates, the side plate 701, the top rod 702 and the clamping tooth plate 703 are synchronously driven to rotate. When the top rod 702 slides into the inner wall of the fixed ring 705 due to the inclined groove 706, the top rod 702 is forced to move relative to the side plate 701, so as to drive the clamping tooth plate 703 to move close to the limiting tooth plate 602. When the top rod 702 slides to contact the inner wall of the fixed ring 705, the clamping tooth plate 703 is clamped with the limiting tooth plate 602 to achieve self-locking. According to the above principle, the position locking of the vertical plate 601, the mounting plate 603, the clamping plate 608 and the rubber pad 609 can be achieved through the self-locking of the clamping tooth plate 703 and the limiting tooth plate 602, so as to ensure the stability of the clamping of the glass body 9 in the turning over process. After the turning over of the glass body 9 is completed, the top rod 702 slides again to cooperate with the inclined groove 706. Through the elastic action of the second spring 704, the clamping tooth plate 703 can be reset to be separated from the limiting tooth plate 602, so as to be unlocked. At this time, through the control of the cylinder 3 to shrink, the clamping mechanism 6 can be driven to move reversely. Through the action of the third spring 810, the movable ring 808 and the convex tooth rod 807 can be reset. Through the meshing transmission between the convex tooth rod 807 and the gear 802, the swing rod 803 and the supporting roller 804 can be restored to the horizontal state to contact the glass body 9, so as to support the glass body 9. Through the elastic action of the first spring 604, the mounting plate 603 can be reset, so as to release the clamping and limiting action of the glass body 9. After the mounting plate 603 is completely reset, the positioning rod 805 slides again to the upper end plane position of the inclined block 806, so as to lock the swing rod 803 and the supporting roller 804, so as to ensure the stability of the supporting of the glass body 9 by the supporting roller 804. Through the continuous shrinkage of the cylinder 3, the clamping plate 608 can continue to move away from the glass body 9, until the clamping plate 608 does not block the glass body 9, and then the reverse side of the glass body 9 can be coated.
