Description

Technical Field

[0001] The present invention relates to the technical field of trimming and grinding equipment, and specifically provides a high-precision trimming and grinding equipment for free-form optical lenses. Background Art

[0002] A free-form optical lens refers to an optical surface lens whose surface shape cannot be described by the mathematical formulas of spherical and aspherical surfaces. Its surface shape has extremely high degrees of freedom and complexity, and can be customized according to specific optical requirements. Its processing steps generally include material selection, blank cutting, milling, and polishing. During the milling and polishing processes, the edges of the lens need to be trimmed. Usually, a clamping device is required to clamp the lens, and then abrasives are used to trim and grind the edges of the lens.

[0003] Common trimming and grinding methods include two types: for lenses with a circular side, when using a clamping device to fix the lens, it is necessary to ensure that its optical axis coincides with the reference axis to ensure precise control of light by the lens. However, the alignment accuracy requirements of the optical axis and the reference axis during the clamping process are high, and it is difficult to fully match in actual operation, affecting the optical performance of the finished product; when grinding lenses with a non-circular side (such as eyeglass lenses), the movement path of the abrasive plate is preset by a program, and the abrasive plate is driven to move along a non-circular contour trajectory.

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] In order to enable those in the technical field to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] Note: For the accuracy and uniformity of direction expression, in this article, the three axes of X, Y, and Z respectively correspond to the three directions in the Cartesian coordinate system.

[0032] Figure 1 It is a schematic diagram of the overall structure of a high-precision trimming and grinding device for a free-form optical lens. The optical lens to be ground is a lens body 6 with a free-form surface and a convex side. The shape of the lens body 6 can be circular or non-circular.

[0033] As Figure 1 - Figure 2 shown, during grinding, a standard part 7 of the lens body 6 and a standard part 8 which is an equal-proportion enlargement of the standard part 7 are required. The standard part 7 and the standard part 8 can be integrally formed by casting or injection molding. It should be ensured that the distance between the sides of the standard part 7 and the standard part 8 is the same at any position.

[0034] As Figure 1 and Figure 3 shown, a positioning component 1 is placed below the lens body 6, the standard part 7 and the standard part 8 for positioning and fixing the lens body 6, the standard part 7 and the standard part 8. The positioning component 1 includes a workbench 101, which is divided into two symmetrical halves and is respectively located on the symmetrical two sides of the lens body 6, the standard part 7 and the standard part 8. An X-axis assembly guide rail 102 is assembled along the surface of the workbench 101, and a moving frame 103 is assembled on the guide rail 102.

[0035] In this embodiment, at least two moving rods 104 that can move along the X-axis are assembled on the surface of the moving frame 103. The moving rods 104 can be driven by electric push rods (not shown in the figure). The end of the moving rod 104 is assembled with a rotatable pressing plate 105 to ensure that when the pressing plate 105 abuts against the surfaces of the lens body 6 and the standard part 7, it can rotate and fit along with the curved surfaces of the two. A rubber strip 106 is arranged on the side of the pressing plate 105 by adhesion, and the rubber strip 106 abuts against the surfaces of the lens body 6 and the standard part 7 at the same time.

[0036] When the electric push rod pushes the moving rod 104 to move, it will drive the pressing plate 105 and the rubber strip 106 to gradually approach the standard part 7 and the lens body 6 until the rubber strip 106 abuts against the sides of the two. Due to the deformable property of the rubber strip 106 itself, it can ensure pressing and fitting, so that the projections of the lens body 6 and the standard part 7 along the Y-axis coincide.

[0037] As Figure 1 、 Figure 4 - Figure 6As shown in the figure, after positioning the lens body 6, the clamping assembly 2 is used to fix the position of the lens body 6. The clamping assembly 2 includes an inverted U-shaped fixing frame 201, which is fixedly assembled at the central position above the workbench 101. Inside the fixing frame 201, two positioning rods 203 that move along the Y-axis are assembled. Suction cups 204 are assembled at the opposite ends of the two positioning rods 203. It should be noted that the suction cups 204 only play an auxiliary adsorption role, and it is still necessary to ensure that the positioning rods 203 are rigidly against the surfaces of the lens body 6 and the second standard part 8, minimizing the offset generated during rotation. Guide grooves 202 are provided on both sides of the fixing frame 201. The ends of the positioning rods 203 are located inside the guide grooves 202 and move along the Z-axis.

[0038] A connecting rod 205 is integrally formed on the surface of the first standard part 7. The position of the connecting rod 205 does not need to be limited in any way. Similarly, a suction cup 204 is provided at the end of the connecting rod 205. The suction cup 204 at this position adsorbs on the surface of the lens body 6, making the lens body 6, the first standard part 7, and the second standard part 8 an integral structure.

[0039] A clamping plate 206 is assembled inside the guide groove 202. The clamping plate 206 can be driven by an electric push rod to move along the Y-axis. A ball 207 is assembled at the end of the positioning rod 203, and the ball 207 abuts against the surface of the clamping plate 206, ensuring that when the integral structure of the lens body 6, the first standard part 7, and the second standard part 8 moves along the Z-axis, it can be more smooth and stable.

[0040] As Figure 1 、 Figure 7 、 Figure 10 - Figure 11 shown in the figure, a grinding assembly 3 is assembled in the positive direction of the lens body 6 to grind and trim the side of the lens body 6. The grinding assembly 3 includes two transmission leather belts 301, which are transmitted along the X-axis. A plurality of abrasive stones 302 are installed between the two transmission leather belts 301. It should be noted that the distance between the abrasive stones 302 is greater than the width of the abrasive stones 302 themselves. Clamping sleeves 305 are provided on both sides of the abrasive stones 302. The clamping sleeves 305 can be made of metal material, and their deformable ability is used to clamp and fix the abrasive stones 302 to facilitate the replacement of the abrasive stones 302. A pressing rod 306 is integrally formed on the surface of the clamping sleeve 305. A plurality of mounting rings 13 are provided on the surface of the transmission leather belt 301. The pressing rod 306 is stuck inside the mounting ring 13 by friction. Threads are provided at the end of the pressing rod 306. By rotating the thread, the position of the pressing rod 306 is changed, so that the end of the pressing rod 306 abuts against the surface of the abrasive stone 302, preventing the abrasive stone 302 from falling off during use. It should be noted that the abrasive stone 302 is in a tangential state with the lens body 6.

[0041] Two mounting brackets 303 are provided, and a roller shaft 304 is assembled between the mounting brackets 303 for driving the transmission of two transmission belts 301. A rolling ring 307 is adjusted on the surface of the pressing rod 306, and the rolling ring 307 abuts against the inside of the mounting bracket 303 to reduce the friction between the abrasive stone 302 and the mounting bracket 303 during movement.

[0042] As Figure 1 , Figure 8 - Figure 9 shown, a support assembly 4 is provided below the standard part II 8 for abutting against the surface of the standard part II 8. The support assembly 4 includes a support frame 401 placed on the ground, a transmission frame 402 is assembled directly above the support frame 401, and an electric push rod 405 is assembled on the surface of the support frame 401 for driving the transmission frame 402 to move along the Z-axis. A plurality of guide rods are also assembled above the support frame 401 to prevent the transmission frame 402 from generating offsets in the Y-axis and Z-axis. A conveyor belt 403 is also assembled on the transmission frame 402 for transmission along the X-axis. The side of the standard part II 8 abuts against the conveyor belt 403, and a bearing plate 404 is assembled inside the transmission frame 402 to provide a supporting force for the standard part II 8.

[0043] As Figure 5 - Figure 6 shown, a driving assembly 5 is assembled inside the fixing frame 201 to rotate the standard part II 8. When the standard part II 8 rotates, its surface will always abut against the conveyor belt 403. Due to the transmission of the conveyor belt 403, the wear generated during the rotation of the standard part II 8 can be effectively reduced, and the accuracy during the grinding process can be improved. The driving assembly 5 includes a cross bar 501 with protrusions on its surface. Two symmetrically placed hanging rings 11 are sleeved on the surface of the cross bar 501. A suspension spring 12 is assembled on the surface of the hanging ring 11, and the top of the suspension spring 12 is fixed on the surface of the fixing frame 201. Two gears 502 are symmetrically assembled on the surface of the cross bar 501, and the gears 502 are adapted to the protrusions of the cross bar 501. The end of the cross bar 501 extends into the guide groove 202, and a gear 503 assembled on the surface of two positioning rods 203 meshes with the gear 502. A support plate 9 and a motor 504 are assembled on the surface of the fixing frame 201. The motor 504 can move along the Z-axis and is used to drive the rotation of the cross bar 501. A compressed support spring 10 is assembled on the surface of the support plate 9, and the top of the support spring 10 abuts against the surface of the motor 504.

[0044] The rotation of the motor 504 drives the rotation of the cross bar 501. Through the meshing of the first gear 502 and the second gear 503, the positioning rod 203 is driven to rotate. When the second standard part 8 rotates, since its surface is always in contact with the surface of the conveyor belt 403, the positioning rod 203 can be driven to move along the Z-axis, indirectly causing the lens body 6 to move. At this time, it can be ensured that the edge of the lens body 6 abuts against the surface of the abrasive stone 302, and the movement of the abrasive stone 302 can achieve the grinding of the edge of the lens body 6.

[0045] The present invention provides a high-precision trimming and grinding device for free-form optical lenses. The staff places the lens body 6, the first standard part 7, and the second standard part 8 inside the fixing frame 201. The push rod drives the movement of the moving rod 104, which will drive the pressing plate 105 and the rubber strip 106 to gradually approach the first standard part 7 and the lens body 6 until the rubber strip 106 abuts against the sides of both. The clamping plate 206 can be driven by an electric push rod to move along the Y-axis until the suction cup 204 abuts against the surfaces of the lens body 6 and the second standard part 8. At this time, the lens body 6 abuts against the surface of the abrasive stone 302, and the second standard part 8 abuts against the surface of the conveyor belt 403. The transmission leather strip 301, the conveyor belt 403, and the motor 504 are started simultaneously. The rotation of the motor 504 drives the rotation of the cross bar 501. Through the meshing of the first gear 502 and the second gear 503, the positioning rod 203 is driven to rotate. When the second standard part 8 rotates, since its surface is always in contact with the surface of the conveyor belt 403, the positioning rod 203 can be driven to move along the Z-axis. At the same time, the lens body 6 will also move due to the connection between the positioning rod 203 and the suction cup 204, ensuring that the edge of the lens body 6 is always abutted against the surface of the abrasive stone 302 for grinding, thereby achieving the trimming and grinding of the edge of the lens body 6.
