[0002] Glass lenses are a commonly used optical material, widely used in eyeglasses and various optical instruments. When glass lenses are produced and processed, they need to be coated to increase protection for the surface of the glass lenses and prevent scratches and wear during use, which will affect their normal use and service life. When coating the glass lenses, a fixed clamping device is needed to clamp the glass lenses to prevent the glass lenses from moving during coating and affecting the coating effect.

[0003] The prior art patent document with the publication number CN212471220U provides a fixing clamping device for coating glass lenses. The fixing clamping device for coating glass lenses clamps and fixes the glass lenses by squeezing the clamping block inwards through a reset spring. The clamping force is small to prevent the clamping block from damaging the glass lenses to be coated. The first protective pad and the second protective pad are made of rubber to protect the glass lenses to be coated and prevent the placement table and the clamping block from scratching the glass lenses. However, the existing CN212471220U patent is only suitable for lenses with single-sided coating. If the lenses need to be coated on both sides, the lenses need to be repeatedly disassembled and assembled, which is not convenient to use. Multiple disassembly and assembly of the lenses takes time, which reduces the lens processing efficiency. Therefore, a clamping device for coating lenses is urgently needed. Utility Model Content

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0023] The following describes an embodiment of the utility model based on its overall structure.

[0024] See also Figure 1-4A clamping device for lens coating includes a clamping mechanism 1, a workbench 11 and a supporting mechanism 15.

The front and rear end surfaces of the first clamping plate 101 are both provided with a first clamping groove 102. The front and rear sides of the first clamping plate 101 are both provided with a second clamping plate 103. The second clamping groove 104 is provided inside the second clamping plate 103. The inner walls of the first clamping groove 102 and the second clamping groove 104 are both attached with a silicone pad. The clamping plate 101, the first clamping groove 102, the second clamping plate 103 and the second clamping groove 104 cooperate with each other to clamp the lens. The inner walls of the first clamping groove 102 and the second clamping groove 104 are fitted with silicone pads. This setting can reduce the damage to the lens during the clamping process and increase the friction of the lens clamping to prevent the lens from falling. The inner rotation of the slide groove 3 is connected to a double-headed reverse screw rod 4, and the rear end of the double-headed reverse screw rod 4 is connected to a first motor 5. The outer side of the double-headed reverse screw rod 4 is threadedly connected to a slider 6. The left end of the first clamping plate 101 is welded to the mounting plate 2, the left end of the second clamping plate 103 is fixedly connected to the slider 6, and the first The second clamping plate 103 is slidably connected to the mounting plate 2 through the slider 6 and the slide groove 3. By starting the second motor 10 to drive the double-headed reverse screw 4 to rotate, the slider 6 is translated along the right side of the mounting plate 2, thereby adjusting the distance between the second clamping plate 103 and the first clamping plate 101, which is convenient for clamping and collecting the lens. A connecting plate 7 is provided on the left side of the mounting plate 2, and the left side of the connecting plate 7 is connected to the second motor 10. Threaded holes are provided inside the connecting plate 7 and the left side of the mounting plate 2, and screws 8 are passed through the inside of the threaded holes. The connecting plate 7 is assembled on the left side of the mounting plate 2 by the screws 8. The device is detachable and easy to transport. The connecting plate 7 A longitudinal support frame 9 is arranged between the second motor 10, and the output shaft of the second motor 10 passes through the longitudinal support frame 9 and is connected to the connecting plate 7 through a bearing, and the longitudinal support frame 9 and the workbench 11 are perpendicular to each other. By starting the second motor 10, the mounting plate 2 and the clamping mechanism 1 can be driven to rotate, and the lens in the clamping mechanism 1 rotates accordingly, which is convenient for coating the double sides of the lens, and the process does not require repeated disassembly and assembly of the lens, thereby improving the lens processing efficiency. The longitudinal support frame 9 provides a stable supporting force for the second motor 10 and the clamping mechanism 1, so that there is a height difference between the clamping mechanism 1 and the workbench 11, and sufficient space is reserved for the rotation of the clamping mechanism 1;

[0025] The workbench 11 is fixed to the bottom end of the longitudinal support frame 9, and two bottom brackets 12 are installed at the lower end of the workbench 11, and a horizontal plate 13 is fixed between the two bottom brackets 12. The supporting mechanism 15 is arranged below the clamping mechanism 1, and the supporting mechanism 15 includes a movable plate 1501, a cylindrical plate 1502, a rubber pad 1503 and an electric push rod 1504. The top of the movable plate 1501 is distributed with a cylindrical plate 1502, and the top of the cylindrical plate 1502 is bonded with a rubber pad 1503. The lower end of the movable plate 1501 is connected with an electric push rod 1504. The lifting and lowering of the movable plate 1501 is controlled by starting the electric push rod 1504. When the lens coating is completed, The movable plate 1501 rises, and the clamping mechanism 1 releases the lens, and the lens falls on the cylindrical plate 1502. The setting of the rubber pad 1503 can prevent the lens from scratching the top of the cylindrical plate 1502 on the one hand, and enhance the friction coefficient of the top of the cylindrical plate 1502 on the other hand to prevent the lens from falling. A circular hole 14 is opened in the middle of the workbench 11, and the output shaft of the electric push rod 1504 passes through the circular hole 14 to connect with the movable plate 1501. The electric push rod 1504 controls the lifting and lowering of the movable plate 1501 through the circular hole 14. The diameter of the output shaft of the electric push rod 1504 is larger than the diameter of the circular hole 14 to prevent the output shaft of the electric push rod 1504 from scratching the workbench 11.

[0026] Working principle: When in use, first place the lens on the top of the cylindrical plate 1502. The setting of the rubber pad 1503 and enhances the friction coefficient of the top of the cylindrical plate 1502, reducing the risk of the lens falling from the top of the cylindrical plate 1502. Then, the second motor 10 is started by the controller, and the second motor 10 drives the double-headed reverse screw 4 to rotate. Under the mutual cooperation of the slider 6 and the slide groove 3, the two second clamping plates 103 approach each other until the two second clamping plates 103 are respectively in contact with the front and rear end surfaces of the first clamping plate 101, and the lens is clamped by the mutual cooperation of the first clamping plate 101, the first clamping groove 102, the second clamping plate 103 and the second clamping groove 104. After the lens is fixed, the electric push rod 1504 is started to control the movable plate 1501 to descend until the lower surface of the movable plate 1501 contacts the workbench 11. When the front side of the lens is coated, the second motor 10 is started to drive the mounting plate 2 and the clamping mechanism 1 to rotate, and the lens in the clamping mechanism 1 rotates accordingly, which is convenient for coating both sides of the lens. The process does not require repeated disassembly and assembly of the lens, thereby improving the lens processing efficiency. After the double-sided coating of the lens is completed, the electric push rod 1504 pushes the movable plate 1501 to rise, the cylindrical plate 1502 supports the lens, the two second clamping plates 103 move away from each other, and the lens falls off the clamping mechanism 1, thus completing the coating and collection of the lens.
