Description

Technical Field

[0001] This invention belongs to the field of lens edging technology, and specifically relates to a camera lens edging device that automatically switches between multiple grinding modes. Background Technology

[0002] As a core video input device in fields such as video conferencing, remote shooting, real-time monitoring, and consumer electronics, the image quality of cameras is closely related to the processing precision of the lens edges. With the continuous upgrading of camera technology, lens design is rapidly developing towards ultra-thinness and high curvature, which places higher demands on processing equipment. Traditional lens processing requires pre-forming with a cutting machine followed by edge smoothing with a grinding machine. Its image quality is highly dependent on the processing precision of the lens edges. As camera lenses evolve towards ultra-thinness and high curvature, equipment needs to support variable edge and mini-stepping edge technologies to match the processing requirements of high-curvature lenses. The challenge of balancing equipment investment and production efficiency for small and medium-sized enterprises still needs to be addressed through cost-efficiency optimization solutions using semi-automatic and fully automatic equipment.

[0003] In existing technologies, traditional lens processing has multiple technical bottlenecks: First, in single-station processing mode, edge grinding and chamfering need to be completed in steps. Multiple clamping and station changes not only lead to cumulative errors affecting optical performance, but also significantly extend the processing cycle of a single lens, making it difficult to meet the high-efficiency requirements of large-scale production; Second, poor material adaptability. Grinding parameters for materials with different hardness, such as optical glass, resin and PC, vary greatly. Traditional equipment needs to frequently change the grinding wheel material to adapt to different materials, resulting in low processing efficiency and insufficient quality stability.

[0004] Therefore, it is necessary to invent a camera lens edge grinding device that automatically switches between multiple grinding modes to solve the above problems. It can achieve multi-process composite processing through integrated design and shorten the production cycle. Summary of the Invention

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] This invention provides, for example Figure 1-15 The camera lens edge grinding device shown includes a support base 1, a lens limiting mechanism 2 fixedly connected to the top of the support base 1, and an edge grinding angle control mechanism 4 and an automatic switching mechanism 5 connected to one side of the lens limiting mechanism 2.

[0043] In one specific embodiment of the present invention, the lens limiting mechanism 2 includes a control base 201, a rotating seat 204 rotatably connected to the top of the control base 201, a positioning groove 202 formed in the middle of the control base 201, a first reduction motor 203 fixedly mounted in the middle of the positioning groove 202, the output end of the first reduction motor 203 fixedly connected to the middle of the rotating seat 204, and a fixing frame 205 fixedly mounted on one side of the control base 201, with a fixing groove 215 formed in the middle of the fixing frame 205. A first positioning screw 216 is rotatably connected to the middle position of the fixed slot 215. A lifting seat 217 is threadedly connected to one end of the outer wall of the first positioning screw 216. A lifting frame 206 is fixedly provided at one end of the top of the lifting seat 217. One end of the outer wall of the lifting frame 206 is inserted and connected to one end of the top of the fixed frame 205. A second reduction motor 207 is fixedly provided at the bottom of the fixed frame 205. The output end of the second reduction motor 207 is fixedly connected to the bottom end of the first positioning screw 216. A lifting plate 208 is fixedly provided at the top of the lifting frame 206.

[0044] Three positioning rods 209 are inserted in the middle of the lifting plate 208. A return spring 210 is inserted at one end of the outer wall of each of the three positioning rods 209. The bottom end of the three positioning rods 209 is connected to a limit frame 212. The top end of the three positioning rods 209 is fixed with a positioning block 211. The bottom end of the limit frame 212 is rotatably connected to a rotating plate 213. The bottom end of the rotating plate 213 and the top end of the rotating seat 204 are both fixed with anti-slip pads 214.

[0045] Both the rotating base 204 and the rotating disk 213 hold the lens body 3 by means of the anti-slip pad 214;

[0046] When a camera lens edging device that automatically switches between multiple grinding modes is required, the lens body 3 is placed on the top of the rotating seat 204. The output end of the second reduction motor 207, which is fixed to the bottom of the fixed frame 205, drives the first positioning screw 216 to rotate. This causes the lifting seat 217, which is threaded to the outer wall of the first positioning screw 216, to drive the lifting frame 206 to rise and fall. This causes the lifting frame 206 to drive the lifting plate 208, which is fixed at one end, to move. This causes the limiting frame 212, which is inserted through the positioning rod 209 and connected to the bottom of the lifting plate 208, to drive the rotating plate 213 to rise and fall. Both the rotating seat 204 and the rotating plate 213 tightly clamp the lens body 3 through the anti-slip pad 214. Through the elastic deformation of the return spring 210 inserted through the outer wall of the positioning rod 209 and the positioning of the positioning block 211, the lens body 3 is elastically protected during the precision clamping process, avoiding the potential problem of lens damage caused by excessive clamping.

[0047] The output end of the first reduction motor 203, which is fixed inside the positioning groove 202, drives the rotating seat 204 to rotate, thereby controlling the lens body 3 to rotate for edge grinding.

[0048] As a specific embodiment of the present invention, the grinding angle control mechanism 4 includes a positioning gear ring 401 fixed to one end of the outer wall of the control base 201 and a rotating frame 404 rotating on the outer wall of the positioning gear ring 401. A support frame 403 is fixedly provided at one end of the top of the fixed frame 205. The top end of the support frame 403 is fixedly connected to the top end of the positioning gear ring 401. Positioning gears 405 are rotatably connected to both sides of the inner wall of the rotating frame 404. The tooth surfaces of the two positioning gears 405 mesh with the tooth surfaces of the positioning gear ring 401. A third drive motor 406 is fixedly provided on one side of the rotating frame 404. The output end of the third drive motor 406 is fixedly connected to the middle position of one of the positioning gears 405. A limiting groove 402 is provided at the middle position of the positioning gear ring 401. One side of the inner wall of the rotating frame 404 slides in contact with one side of the inner wall of the limiting groove 402.

[0049] The output end of the third drive motor 406, which is fixed on one side of the rotating frame 404, drives the positioning gear 405 to rotate, so that the positioning gear 405 meshes and rotates along the tooth surface of the positioning gear ring 401. Through the mutual balancing of the two positioning gears 405, the rotating frame 404 slides stably along the outer wall of the positioning gear ring 401. The positioning of the limiting groove 402 opened inside the positioning gear ring 401 makes the rotation of the rotating frame 404 more stable.

[0050] The automatic switching mechanism 5 includes a positioning frame 501. A rotating plate 505 is rotatably connected to the top of the inner wall of the positioning frame 501. Multiple protective sleeves 506 are connected to the bottom of the rotating plate 505. A rotating ring 509 is connected to the bottom of the multiple protective sleeves 506. A positioning plate 502 is fixedly provided at the bottom of one side of the positioning frame 501. The bottom of the rotating ring 509 is rotatably connected to the top of the positioning plate 502. A grinding wheel 507 is rotatably connected to the middle position of each protective sleeve 506. A first positioning helical gear 508 is fixedly provided at one end of each of the multiple grinding wheels 507, passing through the multiple protective sleeves 506. A second positioning helical gear 503 is rotatably connected to one end of the top of the positioning plate 502. The tooth surface of one of the first positioning helical gears 508 meshes with the tooth surface of the second positioning helical gear 503.

[0051] A first drive motor 510 is fixedly installed at the top of the positioning frame 501. The output end of the first drive motor 510 is fixedly connected to the middle position of the rotating plate 505. A second drive motor 504 is fixedly installed at one end of the bottom of the positioning plate 502. The output end of the second drive motor 504 is fixedly connected to the middle position of the second positioning helical gear 503.

[0052] The output end of the first drive motor 510, fixed to the top of the positioning frame 501, drives the rotating plate 505 to rotate, so that the multiple protective sleeves 506 and multiple grinding wheels 507, which are positioned by the rotating plate 505 and the rotating ring 509, can rotate selectively. When a suitable grinding wheel 507 is selected, the tooth surface of the first positioning helical gear 508, which passes through the protective sleeve 506 and is fixed on one side of the grinding wheel 507, meshes with the tooth surface of the second positioning helical gear 503. The output end of the second drive motor 504, fixed to the bottom of the positioning plate 502, drives the second positioning helical gear 503 to rotate, so that the grinding wheel 507 can be easily rotated for grinding. This not only makes it easy to selectively and automatically change the grinding tools, but also allows the same drive device to drive the replacement, avoiding the need to equip multiple grinding wheels 507 with drive devices and reducing production costs.

[0053] As a specific embodiment of the present invention, a limit control mechanism 7 is fixedly provided at one end of the top of the positioning frame 501;

[0054] The limit control mechanism 7 includes a support base 701 fixed to one end of the top of the positioning frame 501. An electric telescopic rod 702 is fixedly provided at the top of the support base 701. The telescopic end of the electric telescopic rod 702 passes through the support base 701 and is fixedly provided with a limit seat 703. A plurality of limit slots 704 are provided at the top of the rotating plate 505. The bottom end of the limit seat 703 corresponds to the position of one of the limit slots 704.

[0055] Once the grinding wheel 507 is selected according to the material and grinding purpose, the positioning of the support seat 701 fixed at the top of the positioning frame 501 causes the telescopic end of the electric telescopic rod 702 fixed at the top of the support seat 701 to drive the limit seat 703 to move, so that the limit seat 703 is stably inserted into the corresponding limit slot 704 for fixation, maintaining the stability of the grinding operation.

[0056] In one specific embodiment of the present invention, a telescopic control mechanism 6 is connected to the middle position of the rotating frame 404;

[0057] The telescopic control mechanism 6 includes a control frame 603 fixed in the middle of the rotating frame 404. A control slot 605 is provided in the middle of the control frame 603. A second positioning screw 604 is rotatably connected to the middle of the control slot 605. A fourth drive motor 606 is fixedly provided at one end of the control frame 603. The output end of the fourth drive motor 606 is fixedly connected to one end of the second positioning screw 604. A telescopic seat 602 is threadedly connected to one end of the outer wall of the second positioning screw 604. Telescopic frames 601 are fixedly provided at both ends of the telescopic seat 602. One end of each telescopic frame 601 is connected to one end of the positioning frame 501.

[0058] The output end of the fourth drive motor 606, which is fixed to one end of the control frame 603, drives the second positioning screw 604 to rotate. This causes the telescopic seat 602, which is threaded to one end of the outer wall of the second positioning screw 604, to move telescopically through the telescopic frame 601, thereby enabling telescopic control when grinding different positions and sizes of the lens body 3. This improves the ease of operation of the camera lens edging equipment that automatically switches between multiple grinding modes.

[0059] In one specific embodiment of the present invention, an intelligent control panel is fixedly provided on one side of the support base 1. The first drive motor 510, the second drive motor 504, the third drive motor 406, the fourth drive motor 606, the first reduction motor 203, the second reduction motor 207 and the electric telescopic rod 702 are all electrically connected to an external power supply through the intelligent control panel.

[0060] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
