Optical lens forming flexible gripper mechanism

Abstract

This utility model discloses a flexible clamping mechanism for forming optical lenses, including a substrate, a cylinder, and a clamping device. The cylinder is fixed to the bottom of the substrate, and the clamping device is bolted to the bottom of the cylinder. A bidirectional screw is rotatably mounted inside the clamping device via bearings, and two threaded sleeves are threadedly connected to the surface of the bidirectional screw. Advantages: The clamping device, equipped with two clamping seats, rotates via the second bevel gear at the output of a drive motor. Since the bidirectional screw built into the clamping device is connected by the meshing of the first and second bevel gears, and the surface of the bidirectional screw is connected to the two clamping seats by two threaded sleeves respectively, as the motor rotates, the two threaded sleeves move along the surface of the bidirectional screw, respectively driving the corresponding clamping seats to move. This allows the two clamping seats to flexibly clamp the optical lens through flexible clamping plates on their surfaces as they approach each other.

Description

Technical Field

[0001] This utility model relates to the field of optical glass processing accessories technology, specifically to a flexible clamping mechanism for optical lens forming. Background Technology

[0002] Optical glass refers to glass that can alter the direction of light propagation and change the relative spectral distribution of ultraviolet, visible, or infrared light. In a narrow sense, optical glass refers to colorless optical glass; in a broader sense, it also includes colored optical glass, laser glass, quartz optical glass, radiation-resistant glass, ultraviolet-infrared optical glass, fiber optic glass, acousto-optic glass, magneto-optic glass, and photochromic glass. Optical glass is used to manufacture lenses, prisms, mirrors, and windows in optical instruments. Components made of optical glass are key elements in optical instruments.

[0003] When optical glass undergoes processes such as edge grinding, drilling, and quality inspection, it is often necessary to use optical glass clamps to hold it in order to facilitate operation and improve work efficiency. However, existing optical glass clamping devices suffer from problems such as unstable clamping, the need to change different chucks depending on the size of the glass, and the risk of over-clamping, which can easily damage the optical glass.

A cylinder is fixed to the bottom of the substrate, and the clamping device is fixed to the bottom of the cylinder by bolts. A bidirectional screw is rotatably mounted inside the clamping device via bearings. Two threaded sleeves are threadedly connected to the surface of the bidirectional screw, and a clamping seat is fixed to the portion of each threaded sleeve extending to the outside of the clamping device. A flexible clamping plate is fixed to one side of the clamping seat by screws, and an adjustment frame is welded to the other side of the clamping seat.

The left end of the bidirectional screw extends to the outside of the clamping device, and a first bevel gear meshing with the second bevel gear is fixed to the left end of the bidirectional screw. A threaded post is fixed inside the adjustment frame, and a nut is threadedly connected to the surface of the threaded post. A U-shaped abutment is sleeved on the surface of the threaded post, contacting the nut. Both ends of the U-shaped abutment penetrate the clamping seat and contact the back of the flexible clamping plate.

[0008] Furthermore, the flexible clamp is composed of a PVC substrate and a latex pad adhered to its surface, and the surface of the latex pad of the flexible clamp is provided with a grid-like anti-slip surface, and two V-shaped grooves with strip structure are symmetrically opened on the surface of the flexible clamp.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a flexible clamping mechanism for optical lens forming, which has the following advantages:

[0015] This invention features a clamping device with two clamping seats. The second bevel gear at the output of a drive motor rotates. A bidirectional screw integrated into the clamping device is connected by a first bevel gear and a second bevel gear. Two threaded sleeves on the surface of the bidirectional screw are connected to the two clamping seats respectively. As the motor rotates, the two threaded sleeves move along the surface of the bidirectional screw, respectively driving the corresponding clamping seats to move. This allows the two clamping seats to flexibly clamp the optical lens through flexible clamping plates on their surfaces as they approach each other. Simultaneously, rotating the nut on the surface of the threaded column pushes a U-shaped abutment fitted onto the threaded column surface closer to the flexible clamping plate. Combined with symmetrically formed V-shaped grooves on the surface of the flexible clamping plate, the two ends of the U-shaped abutment push against the two ends of the flexible clamping plate, causing it to bend. This method satisfies the need for flexible clamping while being suitable for clamping optical glass of different sizes. Attached Figure Description

[0024] According to an embodiment of the present invention, a flexible clamping mechanism for forming optical lenses is provided.

[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, the flexible clamping mechanism for optical lens forming according to an embodiment of the present invention includes a substrate 1, a cylinder 2, and a clamping device 3. The cylinder 2 is fixed to the bottom of the substrate 1, and the clamping device 3 is fixed to the bottom of the cylinder 2 by bolts. A bidirectional screw 4 is rotatably mounted inside the clamping device 3 via bearings, and two threaded sleeves 9 are threadedly connected to the surface of the bidirectional screw 4. Each threaded sleeve 9 has a clamping seat 8 fixed to the portion extending to the outside of the clamping device 3. A flexible clamping plate 10 is fixed to one side of the clamping seat 8 by screws, and an adjusting frame 11 is welded to the other side of the clamping seat 8. A motor 6 is fixed to the top edge of the clamping device 3, and a second bevel gear 7 is fixed to the output end of the motor 6. The left end of the bidirectional screw 4 extends to the outside of the clamping device 3. On the side, the left end of the bidirectional screw 4 is fixed with a first bevel gear 5 that meshes with the second bevel gear 7. The inner side of the adjusting frame 11 is fixed with a threaded column 13, and the surface of the threaded column 13 is threaded with a nut 14. The surface of the threaded column 13 is fitted with a U-shaped abutment 12 that contacts the nut 14. The two ends of the U-shaped abutment 12 pass through the clamping seat 8 and contact the back of the flexible clamping plate 10. The cylinder 2 is equipped with an air compressor to facilitate the extension and retraction of the cylinder 2. The control method of the cylinder 2 and the motor 6 is controlled by manually starting and stopping the switch. The wiring diagram of the power element and the power supply are common knowledge in the field. Since the present invention is mainly used to protect mechanical devices, the control method and wiring arrangement will not be explained in detail.

[0026] In one embodiment, the flexible clamping plate 10 is composed of a PVC substrate 1 and a latex pad adhered to its surface. The latex pad of the flexible clamping plate 10 has a grid-like anti-slip surface, and two strip-shaped V-shaped grooves 17 are symmetrically formed on the surface of the flexible clamping plate 10. This structure ensures reliable and flexible clamping of the optical lens, and allows the flexible clamping plate 10 to switch flexibly between a flat clamping plate and a trapezoidal clamping plate, making it suitable for clamping square lenses and round lenses of different sizes.

[0027] In one embodiment, the bottom surface of the clamping device 3 is provided with a strip-shaped opening 15, and the inner width of the strip-shaped opening 15 is adapted to the size of the threaded sleeve 9. The upper end face of the clamping seat 8 is in close contact with the housing of the clamping device 3. With this structure, it is easy to make way for the movement of the threaded sleeve 9 and maintain the stability of the movement of the clamping seat 8.

[0028] In one embodiment, the flexible clamping plate 10 has a screw hole 16 in the middle and a rubber pad that abuts against the clamping seat 8 on the back side. With this structure, the flexible clamping plate 10 is easy to install reliably.

[0029] In one embodiment, the U-shaped abutment 12 has a through hole in the middle corresponding to the threaded post 13, and both ends of the U-shaped abutment 12 are provided with inclined surfaces. This structure facilitates the installation of the U-shaped abutment 12 and its contact with the flexible clamp 10.

[0030] In one embodiment, the surface of the clamping seat 8 has two through openings corresponding to the U-shaped abutment 12, and the clamping seat 8 is vertically arranged about the clamping device 3. With this structure, it is easy to move the U-shaped abutment 12 and maintain contact with the flexible clamping plate 10.

[0031] Working principle: First, the cylinder 2 on the substrate 1 is activated to extend, causing the cylinder 2 to push the clamping device 3 closer to the optical glass to be clamped. At this time, the second bevel gear 7 at the output end of the drive motor 6 rotates. Since the bidirectional screw 4 built into the clamping device 3 is connected by the meshing of the first bevel gear 5 and the second bevel gear 7, and the surface of the bidirectional screw 4 is connected to the two clamping seats 8 by two threaded sleeves 9 respectively, as the motor 6 rotates, the two threaded sleeves 9 move along the surface of the bidirectional screw 4, respectively driving the corresponding clamping seats 8 to move, so that the two clamping seats 8... During the process of approaching each other, the optical lens is flexibly clamped by the flexible clamping plate 10 on its surface. At the same time, by rotating the nut 14 on the surface of the threaded post 13, the nut 14 is prompted to push the U-shaped abutment 12 sleeved on the surface of the threaded post 13 closer to the flexible clamping plate 10. Combined with the V-shaped grooves 17 symmetrically opened on the surface of the flexible clamping plate 10, the two ends of the U-shaped abutment 12 push against the two ends of the flexible clamping plate 10 respectively to bend, so that the flexible clamping plate 10 and its raised ends form a clamping structure that fits the size of the optical glass, thus realizing the clamping requirements of optical glass of different sizes.
