[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation of the present application will be clearly and completely described below in conjunction with the drawings in the implementation of the present application.

[0026] like Figure 1 and Figure 2As shown, the present application provides an automatic unloading mechanism 100 of a lens processing device, which includes: a lens conveyor belt 11, a rotating table 12, a rotating table rotation drive component 13, a guide table 14, a guide table telescopic drive component 15, two clamping parts 16 and a clamping part opening and closing drive component 17.

[0027] The lens conveyor belt 11 is arranged horizontally and is used to convey lenses out of the lens processing device. Lenses are output from the end of the lens conveyor belt 11. A turntable 12 is mounted at the end of the lens conveyor belt 11 and is rotatably connected to the lens conveyor belt 11. A turntable rotation drive component 13 is mounted at the end of the lens conveyor belt 11 and is connected to the turntable 12 to drive the turntable 12 to rotate relative to the lens conveyor belt 11. A guide platform 14 is mounted at the end of the turntable 12 away from the lens conveyor belt 11 and is telescopically connected to the turntable 12. A guide platform telescopic drive component 15 is mounted on the turntable 12 and is connected to the guide platform 14 to drive the guide platform 14 to telescope relative to the turntable 12. Two clamping members 16 are mounted at the end of the guide platform 14 away from the turntable 12. The clamping member opening and closing driving component 17 is installed on the guide platform 14 . The clamping member opening and closing driving component 17 connects the two clamping members 16 to drive the two clamping members 16 to open and close in the horizontal direction.

[0028] Through the above arrangement, after the lens is conveyed from the lens conveyor belt 11, it reaches the end of the lens conveyor belt 11. At this time, the turntable 12 is in a horizontal position, so that the lens can be conveyed onto the turntable 12; then the turntable 12 rotates, and due to the action of gravity, the lens slides along the turntable 12 to the guide table 14, and enters between the two clamping members 16, and is limited by the two clamping members 16; then the guide table 14 extends relative to the turntable 12, so that the lens approaches the lens storage frame; when the lens is close enough to the lens storage frame, the two clamping members 16 are released, and the lens falls into the lens storage frame due to the action of gravity.

[0029] Therefore, the present application realizes automatic unloading of lenses, improves lens processing efficiency, reduces required labor costs, and improves production safety of lens processing.

[0030] As an implementation method, the two clamping members 16 each have opposing inclined guide surfaces 161. The distance between the two inclined guide surfaces 161 gradually decreases from the end closest to the rotating platform 12 to the end farther from the rotating platform 12. This arrangement creates a wedge-shaped gap between the two clamping members 16. As a result, once a lens enters between the two clamping members 16, its freedom to move downward along the length of the guide platform 14 is constrained, thereby allowing the lens to be retained in place by the two clamping members 16.

[0031] It should be noted that there are various ways to position the lens between the two clamping members 16. In another implementation, the lens is restrained by the two clamping members 16. Specifically, a detection optical coupler is used to determine whether the lens is about to enter between the two clamping members 16. When the lens is about to enter between the two clamping members 16, the clamping member opening and closing driving component 17 drives the two clamping members 16 to clamp the lens horizontally.

[0032] As an implementation method, the turntable 12 is provided with turntable folding edges 121 on both sides in the longitudinal direction of the turntable 12 to prevent the lenses on the turntable 12 from detaching from the turntable 12 along the width direction of the turntable 12. The guide table 14 is provided with guide table folding edges 141 on both sides in the longitudinal direction of the guide table 14 to prevent the lenses on the guide table 14 from detaching from the guide table 14 along the width direction of the guide table 14. The guide table folding edge 141 on one side has an inclination angle relative to the turntable folding edge 121 corresponding to the side. The guide bevel 161 of the clamping member 16 on one side has an inclination angle relative to the turntable folding edge 121 corresponding to the side, and the inclination angle of the guide table folding edge 141 is greater than or equal to the inclination angle of the guide bevel 161. Through the above arrangement, a secondary guide for the lens is formed. The first-level guide is formed by the opening between the folded edges 141 of the guide platforms on both sides, and the second-level guide is formed by the opening between the guide slopes 161 of the two clamping members 16. The opening angle of the first-level guide is greater than or equal to the opening angle of the second-level guide, so that the lens can be more easily guided between the two clamping members 16.

[0033] As an implementation, the clamping member 16 has a lens retaining portion 162 that protrudes relative to the guide slope 161. The lens retaining portion 162 is used to prevent the lens positioned between the two clamping members 16 from dislodging away from the lens support surface of the guide platform 14. A gap is provided between the lens retaining portion 162 and the guide platform 14 that is greater than the thickness of the lens, thereby allowing the lens to be accommodated between the two clamping members 16.

[0034] It should be noted that the lens limiting portion 162 has a certain length so that the lens limiting portion 162 can limit the lens from the time when the lens enters the two clamping members 16 to the time when the lens leaves the two clamping members 16 .

[0035] As an implementation method, the lens conveyor belt 11, the rotating table 12 and the guide table 14 all have support surfaces for supporting the lenses. When the rotating table 12 rotates to a horizontal position, the support surfaces of the lens conveyor belt 11, the support surfaces of the rotating table 12 and the support surfaces of the guide table 14 are located on the same plane, so that the lenses can smoothly enter from the lens conveyor belt 11 onto the rotating table 12, and can smoothly enter from the rotating table 12 onto the guide table 14.

[0036] As one implementation, a rotating shaft 111 is fixedly mounted on the lens conveyor belt 11, and the rotating platform 12 is rotatably connected to the rotating shaft 111. The rotating platform rotation drive component 13 is a rotary cylinder, which is fixedly mounted on the lens conveyor belt 11. A connecting shaft 131 is fixedly mounted at the end of the rotating cylinder's piston rod. Connecting shaft 131 is rotatably connected to the rotating platform 12 and arranged parallel to the rotating shaft 111, thereby enabling the rotating platform 12 to rotate relative to the lens conveyor belt 11.

[0037] It should be noted that the stroke of the rotating cylinder limits the maximum and minimum rotation angles of the turntable 12: when the piston rod of the rotating cylinder is extended to the maximum stroke, the rotation angle of the turntable 12 is the minimum, and the turntable 12 is in a horizontal position; when the piston rod of the rotating cylinder is extended to the minimum stroke, the rotation angle of the turntable 12 is the maximum (close to 90° or equal to 90°), so that the lens falls naturally due to gravity.

[0038] As an implementation method, the guide platform telescopic drive component 15 is a telescopic cylinder, which is fixedly installed on the rotating platform 12. The piston rod of the telescopic cylinder is fixedly connected to the guide platform 14, thereby realizing the telescopic movement of the guide platform 14 relative to the rotating platform 12.

[0039] As an implementation method, the clamping member opening and closing driving component 17 is an opening and closing cylinder, which is fixedly installed on the guide platform 14. The two piston rods of the opening and closing cylinder are respectively fixedly connected to the two clamping members 16, thereby realizing the relative opening and clamping of the two clamping members 16.

[0040] As a preferred technical solution, the rotating platform 12 is provided with a plurality of telescopic cylinder mounting holes 122 for mounting telescopic cylinders of different strokes. Through these telescopic cylinder mounting holes 122, telescopic cylinders of different strokes can be installed to adapt to different distances between the lens storage frame and the lens conveyor belt 11.

[0041] The automatic unloading mechanism 100 of the lens processing device of the present application works as follows:

[0042] 1. The lens conveyor belt 11 is in operation, so that the lens is conveyed along the length direction of the lens conveyor belt 11 to the end of the lens conveyor belt 11;

[0043] 2. The lens is transported by the lens conveyor belt 11 and then enters the rotating table 12;

[0044] 3. The rotary cylinder drives the rotating table 12 to rotate a certain angle, so that the lens on the rotating table 12 slides onto the guide table 14 and enters between the two clamping members 16. The lens is restrained by the two clamping members 16;

[0045] 4. The telescopic cylinder drives the guide platform 14 to extend relative to the rotating platform 12, so that the lens moves closer to the lens storage frame. At the same time, the rotating cylinder can adjust the angle of the rotating platform 12 so that the lower end of the guide platform 14 can adapt to the position of the lens in the lens storage frame;

[0046] 5. The clamping cylinder drives the two clamping parts 16 to open, and the lens falls due to gravity and enters the lens storage frame;

[0047] 6. All components are reset and the rotating platform 12 returns to the horizontal position.

[0048] It should be noted that the position of the lens in the automatic unloading mechanism 100 can be determined by detecting the optical coupler, and the actions of the rotating cylinder, telescopic cylinder and clamping cylinder can be controlled according to the position of the lens in the automatic unloading mechanism 100, thereby improving the accuracy of automatic unloading of the lens.

[0049] It should be noted that the lenses are arranged at intervals on the lens conveyor belt 11 , and the interval between two lenses is such that the next lens does not enter the rotating platform 12 before the rotating platform 12 returns to a horizontal position.

[0050] like Figure 3 and Figure 4 As shown, the present application also provides a lens processing device 1, which has the above-mentioned automatic unloading mechanism 100 and a lens storage frame mechanism 200. The lens storage frame mechanism 200 is at least partially located below the automatic unloading mechanism 100, and the automatic unloading mechanism 100 places the lens into the lens storage frame mechanism 200.

[0051] Specifically, the lens storage frame mechanism 200 includes a lens storage frame 21, a first lens storage frame moving mechanism 22, and a second lens storage frame moving mechanism 23. The first lens storage frame moving mechanism 22 is used to drive the lens storage frame 21 to move along a first direction, which is along the length of the lens conveyor belt 11. The first lens storage frame moving mechanism 23 is used to drive the lens storage frame 21 to move along a second direction, which is perpendicular to the first direction and along the horizontal direction. In this application, both the first lens storage frame moving mechanism 22 and the second lens storage frame moving mechanism 23 utilize linear guides.

[0052] Through the above arrangement, the lens storage frame 21 can move along the first direction and the second direction, so that the automatic unloading mechanism 100 can place the lens at any position in the lens storage frame 21 .

[0053] It should be noted that the lens processing device can be a lens mold opening machine, which is used to open the mold of the lens. Before the lens is cast, mold A and mold B are fixed together with tape; when the lens is cast, the liquid lens material is poured between mold A and mold B, and the casting is completed after the lens material solidifies; after the lens is cast, the lens mold opening machine is used to open the mold, that is, the tape is cut to separate mold A and mold B, thereby facilitating the separation of the lens. The lens processing device can also be a lens edge turning machine, which is used to edge the lens blank. The lens processing device can also be a lens casting machine, etc.
