[0002] A lens is a transparent component in an optical instrument or eyeglasses. It is usually made of optical materials such as glass and resin and has one or more curved surfaces. It is often paired with an eyeglass frame to make eyeglasses. During the processing of lenses, in order to ensure that the lenses do not move during processing, clamping devices are often used to firmly fix them.

[0019] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0020] This utility model discloses a positioning device for lens processing. The positioning device mainly includes a base 1 and an adjustment mechanism 2. The adjustment mechanism 2 is mounted on the base 1 and includes a first adjustment component 21 and a second adjustment component 22. The first adjustment component 21 includes a first fixing plate 210 fixed to the base 1, with a first threaded rod 211 threadedly connected to the first fixing plate 210. One end of the first threaded rod 211 is rotatably connected to a first positioning block 212. The second adjustment component 22 includes a second fixing plate 220 fixed to the base 1, with a second threaded rod 221 threadedly connected to the second fixing plate 220. One end of the second threaded rod 221 is rotatably connected to a second positioning block 222. In this device, the first adjustment component 21 and the second adjustment component 22 respectively control the position of the lens in two vertical directions on a horizontal plane. By rotating the threaded rod, the positioning block can be moved along the thread direction, thereby fine-tuning the lateral and longitudinal positions of the lens to ensure that the lens is at a preset coordinate origin or a specified position during processing.

[0021] Both the first positioning block 212 and the second positioning block 222 have a buffer pad on their opposite sides, and the buffer pad is made of rubber. The rubber buffer pad on the opposite side of the first positioning block 212 and the second positioning block 222 mainly disperses the clamping force through elastic deformation, avoiding scratches or cracks on the lens edge due to hard contact. At the same time, it uses the friction of rubber to enhance the clamping stability. Its flexible characteristics can also adapt to lens surfaces with different curvatures, reduce lens deformation caused by clamping, and improve processing safety while ensuring positioning accuracy.

[0022] The device also includes an angle adjustment mechanism 3, which includes a support base 31 fixed on the base 1. A rotating disk 32 is rotatably connected to the support base 31. The rotating disk 32 is provided with a fixing component 4 for fixing the lens. The support base 31 is provided with a locking component 5 for locking the angle of the rotating disk 32. The angle adjustment mechanism 3 is rotatably connected to the rotating disk 32 via the support base 31 on the base 1, providing a basis for the rotation adjustment of the lens. The fixing component 4 on the rotating disk 32 can firmly fix the lens and prevent the lens from shifting during adjustment. The locking component 5 on the support base 31 can firmly lock the rotating disk 32 after it has rotated to the required angle, preventing the angle from shifting due to vibration or other factors during processing. This ensures that the lens maintains accurate positioning in processes requiring specific angles, such as oblique cutting and irregular shape processing, thereby improving processing accuracy and yield.

[0023] The fixing component 4 includes multiple fixing rods 41 fixed on the rotating disk 32. Each fixing rod 41 has a suction cup 42 at one end. The suction cup 42 uses the principle of vacuum adsorption to fit tightly against the lens surface, providing a stable planar fixing force for the lens. It is especially suitable for fixing thin or high-precision optical lenses and avoiding deformation caused by mechanical clamping. The multiple suction cups 42 are distributed to distribute the force evenly, preventing the lens from being damaged due to excessive local pressure. At the same time, they work with the rotating disk 32 to achieve angle adjustment, so that the lens remains stable during rotation and meets the requirements of different processing techniques for lens posture.

[0024] The locking assembly 5 includes an arc-shaped rack 51 fixed on the support base 31, a gear 52 meshing with the arc-shaped rack 51 on the rotating disk 32, and a locking bolt 53 for locking the rotation of the gear 52 on the rotating disk 32. In the locking assembly 5, the arc-shaped rack 51 fixed on the support base 31 meshes with the gear 52 on the rotating disk 32. By rotating the gear 52 along the rack 51, the angle of the rotating disk 32 can be finely adjusted. When the rotating disk 32 rotates to the required angle, tightening the locking bolt 53 on the rotating disk 32 can restrict the rotation of the gear 52, thereby firmly locking the rotating disk 32 and preventing the lens from shifting due to vibration, external force, etc. during processing. This ensures the accuracy and stability of the lens processing angle and meets the requirements of high-precision processing scenarios such as beveling and grinding.

[0025] Working process: When the positioning device for lens processing is working, the lens is first placed horizontally on the rotating disk 32 and fixed by suction cup 42 at the end of the fixing rod 41. At this time, according to the lens size, the operator rotates the first threaded rod 211 in the first adjustment component 21 and the second threaded rod 221 in the second adjustment component 22 to initially adjust the position of the first positioning block 212 and the second positioning block 222 so that the distance between them is slightly larger than the lens size, leaving space for the lens to be placed. After the lens is fixed on the suction cup 42, the first threaded rod 211 and the second threaded rod 221 are finely adjusted again. As the threaded rod rotates, the first positioning block 212 and the second positioning block 222 move slowly along the axis of the threaded rod until the relative buffer pads gently contact the two sides of the lens. When the angle needs to be adjusted, the rotating disk 32 is rotated, and the gear 52 meshes and rotates on the arc rack 51. After adjusting to the appropriate angle, the locking bolt 53 is tightened to lock the angle of the rotating disk 32 through the gear, thereby completing the precise fixing of the lens after horizontal positioning and angle adjustment. During contact, the soft rubber material of the buffer pad adheres to the lens surface, preventing scratches, indentations, or other damage caused by rigid contact. After the positioning block contacts the lens, the threaded rod precisely controls its position, accurately positioning the lens horizontally between the two blocks. This ensures the lens is in the precise location required for processing, while the elasticity of the buffer pad provides appropriate clamping force to prevent displacement of the lens during processing.

[0026] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
