[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described 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.
[0025] Please refer to Figures 1-3As shown in the figure, an optical lens cold processing loading and unloading mechanism includes a bracket 3. The front end of the bracket 3 is rotatably connected to a rotating frame 5. The rear end of the bracket 3 is fixedly connected to a handle 1. The rotating frame 5 is driven to rotate by a servo motor 7. A plurality of suction cups 4 are fixedly connected to the outside of the rotating frame 5 along its circumference. The suction cup 4 includes a rubber disc 11 and a housing 14. The housing 14 is fixedly connected to the rotating frame 5. The edge of the rubber disc 11 is fixedly connected to the housing 14. An armature 13 is fixedly connected to the middle of the rubber disc 11. An electromagnet 15 is fixedly connected to the position corresponding to the armature 13 on the inner side of the housing 14.
[0026] By fixedly connecting a plurality of suction cups 4 to the outside of the rotating frame 5 and driving the rotating frame 5 to rotate by the servo motor 7, the positions of the suction cups 4 are adjusted so that a plurality of lenses are sequentially adsorbed by the plurality of suction cups 4, avoiding frequent movement between the equipment and the tray, thereby improving the loading and unloading efficiency. When adsorbing the lens, the rubber disc 11 is covered on the lens surface, the electromagnet 15 is controlled to be powered on, the electromagnet 15 attracts the armature 13, the rubber disc 11 generates elastic deformation, the cavity between the rubber disc 11 and the lens increases, the air pressure decreases, and under the action of the external air pressure, the rubber disc 11 adsorbs and fixes the lens.
[0027] Specifically, the diameter of the suction cup 4 is smaller than the diameter of the lens, so that the edge of the rubber disc 11 can be attached to the lens surface to avoid air leakage.
[0028] Specifically, a fixed shaft 9 is fixedly connected to the front end of the bracket 3. The rotating frame 5 is rotatably connected to the fixed shaft 9 through a bearing.
[0029] In order to facilitate the connection between the electromagnet 15 and the power supply, a conductive slip ring 10 is sleeved outside the fixed shaft 9. The electromagnet 15 is connected to the power supply through the conductive slip ring 10. Specifically, the stator of the conductive slip ring 10 is fixedly connected to the fixed shaft 9, and the rotor of the conductive slip ring 10 is fixedly connected to the rotating frame 5.
[0030] In some embodiments, a toothed ring 6 is fixedly connected to one side of the rotating frame 5. The servo motor 7 is fixedly connected to the bracket 3. A gear 8 meshing with the toothed ring 6 is fixedly connected to the output shaft of the servo motor 7. Through the transmission of the toothed ring 6 and the gear 8, the transmission is more accurate, so that the servo motor 7 drives the rotating frame 5 to rotate a preset angle to adjust the positions of the suction cups 4.
[0031] In order to facilitate covering the rubber disc 11 on the lens surface, the central axis of the rubber disc 11 is perpendicular to the axis of the rotating frame 5, so as to control the rubber disc 11 to be parallel to the lens surface through the handle 1, avoiding an angle between the rubber disc 11 and the lens surface, resulting in the failure of the suction cup 4 to adsorb and fix the lens.
[0032] To avoid interference between the bracket 3 and the suction cup 4 when adsorbing the lens, a U-shaped rotating bracket 5 is adopted. Preferably, the width of the position of the bracket 3 corresponding to the suction cup 4 is greater than the diameter of the lens, so that the suction cup 4 can rotate past the bracket 3 after adsorbing the lens.
[0033] Working principle: During use, the suction cup 4 is attached to the lens surface, and then the electromagnet 15 is activated. The electromagnet 15 adsorbs the armature 13 to drive the rubber disk 11 to deform. The cavity between the rubber disk 11 and the lens increases, and the air pressure decreases. Under the action of the external air pressure, the rubber disk 11 adsorbs and fixes the lens. The handle 1 is lifted to move the lens away from the material tray or processing equipment. Then, the rotating bracket 5 is driven by the servo motor 7 to rotate, so that the next suction cup 4 rotates to the current position, and the adsorption operation is performed again. This cycle continues until all the suction cups 4 have adsorbed the lenses.
[0034] When it is necessary to place the lens down, the lens is brought close to the material tray or processing equipment, the electromagnet 15 of this suction cup 4 is turned off, and the rubber disk 11 returns to its original position under the action of its own elasticity, the air pressure is balanced, and the lens detaches from the rubber disk 11 and falls onto the material tray. The handle 1 is lifted to move the rotating bracket 5 away from the material tray, and then the rotating bracket 5 is driven by the servo motor 7 to rotate, so that the next suction cup 4 rotates to the current position, and the discharging operation is performed again.
[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
