Description

Technical Field

[0001] The utility model relates to the technical field of glass processing, in particular to a chamfer grinding device for optical glass. Background Technique

[0002] Optical glass refers to glass that can change the propagation direction of light and can change the relative spectral distribution of ultraviolet, visible or infrared light. It is widely used in various optical devices, such as telescopes, microscopes, cameras, etc.

[0003] During the production and processing of optical glass, it is necessary to perform grinding and processing on the chamfered edges. Through the grinding treatment of the chamfered edges, the edges of the optical glass become smoother, without sharp edges, and the overall appearance looks more beautiful and generous. In addition, problems such as sharpness and burrs at the edges of the glass can be eliminated, avoiding being scratched or stabbed by personnel during use or contact, ensuring the safety of the users. At the same time, the edge grinding treatment can remove the small cracks and microcracks formed at the edges of the original glass due to cutting, eliminate local stress concentration, and reduce the scattering and loss of light at the edges, thereby improving the light transmittance and imaging quality of the optical glass. However, in the traditional grinding and processing of optical lenses, the structure of clamping and fixing the optical lens and the grinding head moving around the optical lens for grinding is generally adopted. Although the chamfer grinding of the optical lens can be realized, the structure of the grinding head moving around the optical lens for grinding is relatively complex, not easy to operate and control, and has a high failure rate. Therefore, this application proposes a chamfer grinding device for optical glass. Content of the Utility Model

[0004] The purpose of the utility model is to provide a chamfer grinding device for optical glass, which can realize the efficient grinding and processing of the chamfers of optical lenses, and is suitable for the chamfer grinding and processing of optical lenses with different thicknesses and radius sizes, and has high adaptability.

The lead screw threadedly penetrates the sliding seat, and the frame body is vertically mounted on the sliding seat.

[0010] Preferably, the second driving mechanism includes a slider movably fitted in the frame body and a second electric push rod vertically mounted at the top of the frame body.

The cross arm presses tightly on the upper surface of the optical lens, so that the optical lens can rotate following the cross arm and the support disk. Cooperating with the first driving mechanism to drive the support disk to rotate, the support disk is driven to drive the optical lens to rotate. Thus, in the rotating state of the optical lens, the grinding head can be used to efficiently grind and process the corners of the optical lens. Compared with the traditional method of using the grinding head to move in a circular motion to grind the corners of the optical lens, it is more convenient to operate and has a higher grinding effect.

[0015] Through the arrangement of the pushing mechanism, the second motor is started to drive the lead screw to rotate, so that the sliding seat drives the frame body to move closer to or away from the support disk, and the distance between the grinding head and the support disk can be adjusted, which is suitable for grinding and processing the corners of optical lenses with different radius sizes.

[0024] Embodiment

[0025] Please refer to Figures 1 to 5 , the present utility model preferably provides the following technical solutions:

[0026] An edge grinding device for optical glass, comprising a processing table 1, on which a grinding mechanism 7 for grinding the edges of optical glass is provided; a support disk 2 rotatably mounted on the processing table 1, and a first driving mechanism 3 for driving the support disk 2 to rotate is provided on the processing table 1; a first electric push rod 4 vertically fixed on the processing table 1, a cross arm 5 horizontally fixed to the telescopic end of the first electric push rod 4, and a pressing disk 6 rotatably mounted at the end of the cross arm 5 and coaxially distributed with the support disk 2. In this structural manner, the optical lens is placed on the support disk 2. When the first electric push rod 4 is started to contract, it drives the cross arm 5 and the pressing disk 6 to press down. The cross arm 5 presses tightly against the upper surface of the optical lens, so that the optical lens can rotate following the cross arm 5 and the support disk 2. In cooperation with the first driving mechanism 3 driving the support disk 2 to rotate, the support disk 2 is driven to drive the optical lens to rotate. Thus, when the optical lens is in a rotating state, the grinding mechanism 7 can be used to efficiently grind and process the edges of the optical lens. Compared with the traditional method of grinding the edges of the optical lens by the circular motion of the grinding mechanism 7, it is more convenient to operate and has a higher grinding effect.

[0027] As a preferred implementation manner of this embodiment, the first driving mechanism 3 includes an assembly groove 25 opened on the processing table 1, a driven gear disk 22 and a driving gear disk 23 rotatably mounted in the assembly groove 25, and a third motor 24 installed in the assembly groove 25 for driving the driving gear disk 23 to rotate. The driving gear disk 23 and the driven gear disk 22 are meshed with each other. The support disk 2 is coaxially fixed to the driven gear disk 22. When the third motor 24 is started to drive the driving gear disk 23 to rotate, under the transmission cooperation of the driving gear disk 23 and the driven gear disk 22, the support disk 2 can be driven to drive the optical lens to rotate for the grinding and processing of the edges of the optical lens.

[0028] As a preferred implementation manner of this embodiment, the grinding mechanism 7 includes a support arm 8 horizontally fixed on one side of the top of the processing table 1, a frame body 9 installed on the support arm 8, and a grinding head 12 installed on the side of the frame body 9 facing the support disk 2. A second driving mechanism 13 for driving the grinding head 12 to lift is provided on the frame body 9. A pushing mechanism for driving the frame body 9 to move closer to or away from the support disk 2 is provided on the support arm 8. The grinding head 12 is used for grinding and processing the edges of the optical lens. The pushing mechanism is used to adjust the distance between the grinding head 12 and the support disk 2, which is suitable for grinding the edges of optical lenses with different radius sizes. The second driving mechanism 13 is used to adjust the height of the grinding head 12, which is suitable for grinding the edges of optical lenses with different thicknesses.

[0029] In this embodiment, the pushing mechanism includes a chute 14 formed in the support arm 8, a sliding seat 15 slidably fitted in the chute 14, a lead screw 16 rotatably installed in the chute 14, and a second motor 17 installed at the end of the support arm 8 for driving the rotation of the lead screw 16. The lead screw 16 threadedly penetrates through the sliding seat 15, and the frame 9 is vertically installed on the sliding seat 15. By starting the second motor 17 to drive the rotation of the lead screw 16, the sliding seat 15 is driven to move the frame 9 closer to or away from the support disk 2, so as to adjust the distance between the grinding head 12 and the support disk 2, which is suitable for the corner grinding of optical lenses with different radius sizes.

[0030] In this embodiment, the second driving mechanism 13 includes a slider 18 movably fitted in the frame 9 and a second electric push rod 19 vertically installed at the top of the frame 9. The telescopic end of the second electric push rod 19 is connected to the slider 18, and the grinding head 12 is assembled on the slider 18. A mounting block 10 is fixed on the side of the slider 18 facing the support disk 2, and the grinding head 12 is rotatably installed on the side of the mounting block 10 facing the support disk 2. A first motor 11 for driving the rotation of the grinding head 12 is embedded in the mounting block 10. Thus, by starting the second electric push rod 19 to drive the slider 18 to move up and down, the height of the grinding head 12 can be adjusted, which is suitable for the corner grinding of optical lenses with different thicknesses.

[0031] In this embodiment, a guide groove 20 is vertically formed on the side wall of the frame 9, and a rib 21 slidably engaged with the guide groove 20 is provided on the slider 18 for guiding the up and down movement of the slider 18.

[0032] During use, the optical lens is placed on the support disk 2. The first electric push rod 4 is started to contract to drive the cross arm 5 and the pressing disk 6 to press down. The cross arm 5 presses tightly on the upper surface of the optical lens, so that the optical lens can rotate following the cross arm 5 and the support disk 2. Subsequently, the third motor 24 is started to drive the driving gear disk 23 to rotate. Under the transmission cooperation of the driving gear disk 23 and the driven gear disk 22, the support disk 2 is driven to drive the optical lens to rotate. Thus, when the optical lens is in a rotating state, the grinding head 12 can be used to efficiently grind the corners of the optical lens. Further, the second motor 17 is started to drive the rotation of the lead screw 16, and the sliding seat 15 is driven to move the frame 9 closer to or away from the support disk 2, so as to adjust the distance between the grinding head 12 and the support disk 2, which is suitable for the corner grinding of optical lenses with different radius sizes. The second electric push rod 19 is started to drive the slider 18 to move up and down, so as to adjust the height of the grinding head 12, which is suitable for the corner grinding of optical lenses with different thicknesses, and has high adaptability.
