DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1 , 2 , Figures 3 and 4, the present utility model provides a technical solution: an optical lens production turnover device, including: a support plate 1 with a long strip hole 5 in the middle; a moving slide plate 2 is slidably installed on the top of the support plate 1 through a linear guide rail; a turnover part is placed on the top of the moving slide plate 2, the turnover part includes a transmission rod 6 with a rectangular structure, a lifting component for driving the transmission rod 6 to lift is arranged at the top of the transmission rod 6, and a driving rack 10 for driving the transmission rod 6 to rotate is arranged on the top of the moving slide plate 2; a clamping part is placed at the bottom of the transmission rod 6, the clamping part includes a vacuum chuck 12 and a limiting pressing piece 13 that cooperates with the vacuum chuck 12, the vacuum chuck 12 is connected to a vacuum generator through an air pipe, and a blanking pressing plate 16 is arranged inside the limiting pressing piece 13. When the suction of the vacuum chuck 12 is withdrawn, the limiting pressing piece 13 pushes the lens down between the limiting pressing piece 13 and the vacuum chuck 12.

[0024] It should be noted that when the lens of the present utility model is located between the limiting pressing piece 13 and the vacuum chuck 12, the lifting component drives the transmission rod 6 to move downward. The limiting pressing piece 13 is of an arc structure and the center of the circle is located on the side away from the vacuum chuck 12. Under the extrusion of the limiting pressing piece 13, the lens contacts the vacuum chuck 12. During this period, the lens pushes the blanking pressing plate 16 upward. When the blanking pressing plate 16 moves to a specified position and contacts the butt contact switch, the controller controls the vacuum generator to work, so as to suck the lens through the vacuum chuck 12. Subsequently, the lifting component drives the vacuum chuck 12 to rise, and the driving rack 10 drives the transmission rod 6 to turn over through the driving gear 7. At the same time, the moving slide plate 2 moves to one side, so that the turned-over lens is directly above the original position. The lifting component drives the vacuum chuck 12 to descend, and the vacuum generator controls the vacuum chuck 12 to withdraw the suction. When the lifting component drives the vacuum chuck 12 to rise, the blanking pressing plate 16 pushes the lens down so that it stays in place.

[0025] Please refer to Figure 2 As shown in the figure, a driving cylinder 4 is fixedly connected to the bottom of the support plate 1, and the output end of the driving cylinder 4 is fixedly connected to a connecting plate 3 with an L-shaped structure. One end of the connecting plate 3 is fixedly connected to the moving slide plate 2.

[0026] It should be noted that when the lens of the present utility model rotates and flips along the transmission rod 6, the driving cylinder 4 drives the moving slide plate 2 to slide on the top of the support plate 1 through the connecting plate 3, so as to adjust the position of the lens after rotation, making the rotated lens directly above the original position, which is convenient to place it back in place after rotation.

[0027] Please refer to Figure 1 、 3 As shown in the figure, the lifting assembly includes a second double-axis cylinder 9. The piston end of the second double-axis cylinder 9 is fixedly connected to the moving slide plate 2, and the fixed end of the second double-axis cylinder 9 is fixedly connected with a lifting plate 8. The end of the transmission rod 6 passes through the middle of the long strip hole 5 and is rotatably connected to the lifting plate 8.

[0028] It should be noted that when the second double-axis cylinder 9 of the present utility model expands and contracts, it drives the lifting plate 8 to rise and fall. The top of the transmission rod 6 is circular and is rotatably connected to the lifting plate 8, so as to drive the transmission rod 6 to rise and fall through the lifting plate 8. The width of the long strip hole 5 is greater than the diagonal length of the transmission rod 6, so that the transmission rod 6 can rise, fall or move inside the long strip hole 5.

[0029] Please refer to Figure 1 、 3 As shown in the figure, a driving gear 7 is rotatably connected to the middle of the moving slide plate 2. The transmission rod 6 is slidably connected up and down in the middle of the driving gear 7. The driving rack 10 is meshed with the driving gear 7. The top of the moving slide plate 2 is fixedly connected with a first double-axis cylinder 11, and the output end of the first double-axis cylinder 11 is fixedly connected with the driving rack 10.

[0030] It should be noted that the driving gear 7 of the present utility model is provided with a rectangular hole that cooperates with the transmission rod 6, so that the driving gear 7 can drive the transmission rod 6 to rotate. At the same time, the transmission rod 6 can slide up and down in the middle of the driving gear 7. When the transmission rod 6 needs to be rotated, the first double-axis cylinder 11 drives the driving gear 7 to rotate through the driving rack 10, and the driving gear 7 drives the transmission rod 6 to rotate, so as to realize the lifting and rotation of the lens and facilitate its rapid flipping.

[0031] Please refer to Figure 2 、 4 As shown in the figure, a limiting pressing piece 13 is fixedly connected to the outside of the transmission rod 6. A limiting slide rod 14 is slidably connected to the top of the limiting pressing piece 13. The bottom of the limiting slide rod 14 is fixedly connected with a blanking pressing plate 16. A return spring 15 is sleeved outside the limiting slide rod 14 and between the limiting pressing piece 13 and the blanking pressing plate 16. One end of the blanking pressing plate 16 is slidably connected to the transmission rod 6.

[0032] It should be noted that the limit pressing piece 13 of the present utility model is a metal elastic piece. The elastic force of the return spring 15 and the gravity of the lens are greater than the frictional force between the vacuum suction cup 12 and the limit pressing piece 13. When the limit pressing piece 13 and the vacuum suction cup 12 are located above the lens and move downward, the lens is located between the limit pressing piece 13 and the vacuum suction cup 12. The pressure of the limit pressing piece 13 will cause the lens to closely adhere to the vacuum suction cup 12, facilitating its fixation through the vacuum suction cup 12. When the vacuum suction cup 12 cancels the suction force, the return spring 15 cooperates with the unloading pressing plate 16 to keep the lens in place.
