Description

Technical Field

[0001] This utility model relates to the field of optical component processing technology, specifically a sapphire irregular-shaped component concave-convex surface arc beveling machine. Background Technology

[0002] The beveling technique for irregularly shaped sapphire components is a crucial step in sapphire processing. Due to its high hardness, high melting point, excellent optical properties, and chemical stability, sapphire is widely used in LED substrates, consumer electronics, and optical components. Currently, sapphire wafer beveling is typically achieved using beveling machines, which utilize rotating grinding wheels to polish and bevel the sapphire wafer. However, due to sapphire's high hardness, traditional beveling processes suffer from several problems, such as beveling residue, uneven width, edge chipping, and cracks.

[0003] A Chinese patent with publication number CN210388631U discloses a chamfering machine for irregularly shaped sapphire optical parts, including an operating table with a motor bracket inside. A motor is mounted on top of the motor bracket, and a connecting rod is connected above the motor output end. A concave groove with cleaning fluid is located in the center of the top of the operating table. Lifting machines are installed above both ends of the operating table, each containing a helical horizontal bar and a helical vertical bar.

[0027] Combination Figures 1-4 A sapphire irregular-shaped part concave-convex surface arc chamfering machine includes an operating table 1. A lifting seat 11 is fixedly installed on one side of the top of the operating table 1. A support plate 12 is fixedly connected to the output end of the lifting seat 11. A servo motor 2 is fixedly installed in the middle of the outer wall of one side of the support plate 12. An adjusting arm 21 is fixedly connected to the output shaft of the servo motor 2. A frustum 22 is rotatably provided in the middle of the side wall of the support plate 12. The output shaft of the servo motor 2 passes through the frustum 22. One end of the frustum 22 is rotatably connected to the support plate 12, and the other end is fixedly connected to the adjusting arm 21. A positioning element 3 is provided at the other end of the adjusting arm 21. A limiting element 4 is provided on the positioning element 3 to effectively limit and fix the sapphire irregular-shaped part, ensuring that the irregular-shaped part will not be displaced during processing. A movable groove 210 and a circular groove are opened at the end of the adjusting arm 21 away from the frustum 22 to provide space for the installation and movement of the positioning element 3, so that the positioning element 3 can perform corresponding movements on the adjusting arm 21.

[0028] The limiting component 4 includes a base 41, which provides an installation foundation for each component. A connector 411 is fixedly installed at the center of the top of the base 41. A rectangular groove 410 is opened in the middle of the base 41. A gear 412 is rotatably installed on the inner wall of the top of the rectangular groove 410. A clamping wing 42 is slidably connected to the long side wall of the base 41. A toothed belt 6 is provided on one side of the end of the clamping wing 42 that extends into the base 41. The toothed belt 6 meshes with the gear 412. The gear 412, through meshing with the toothed belt 6 and the toothed groove 430, realizes the linkage between the clamping wing 42 and the straightening plate 43, thereby clamping and straightening the irregular part. The clamping wing 42 clamps the irregular part from both sides. To ensure stability, a straightening plate 43 is slidably provided on the short side wall of the base 41. The end of the straightening plate 43 that extends into the base 41 has a toothed groove 430. One side of the toothed groove 430 meshes with a gear 412. An electric telescopic rod 44 is fixedly connected to the side wall of the straightening plate 43. The output end of the electric telescopic rod 44 is fixedly connected to the short side wall of the base 41 to provide power for the movement of the straightening plate 43. A buffer spring 45 is sleeved on the electric telescopic rod 44. The buffer spring 45 is located between the straightening plate 43 and the side wall of the base 41 to play a buffering role. The straightening plate 43 can adjust the extension length of the clamping wing 42 to ensure machining accuracy.

[0029] The positioning component 3 includes a reduction motor 31, which is fixedly installed on the outer wall of one side of the adjusting arm 21. The output shaft of the reduction motor 31 passes through the circular groove and is fixedly connected to a threaded bushing 32. The threaded bushing 32 is rotatably mounted on the inner wall of one side of the adjusting arm 21. The other end of the threaded bushing 32 is screwed to a connecting rod 33. The threaded bushing 32 drives the linear reciprocating movement of itself on the circular groove through the threaded connection with the connecting rod 33. A connecting piece 411 is sleeved on the connecting rod 33. Washers 34 are sleeved on both sides of the connecting piece 411 on the connecting rod 33. During the movement of the connecting rod 33, the washers 34 on both sides of the connecting piece 411 are pushed to achieve the loosening and clamping of the connecting piece 411.

[0030] On the panel of the operating table 1 near the lifting seat 11, there are symmetrically arranged concave abrasives 51 and convex abrasives 52. Both concave abrasives 51 and convex abrasives 52 are rotatably mounted on the operating table 1. The rotation of concave abrasives 51 and convex abrasives 52 can perform uniform arc chamfering on the concave and convex surfaces of sapphire irregular parts. Rotary motors 5 are fixedly installed on the operating table 1 at the positions corresponding to concave abrasives 51 and convex abrasives 52. The output shafts of the two rotary motors 5 are fixedly connected to the connecting seats at the bottom of concave abrasives 51 and convex abrasives 52, respectively. The rotary motors 5 provide power for the rotation of concave abrasives 51 and convex abrasives 52, so that the abrasives can process at a suitable speed.

[0031] Working principle: First, start the lifting seat 11 on the operating table 1 to adjust the height of the support plate 12. Servo motor 2 drives adjusting arm 21 to rotate above the mold to be processed. Positioning part 3 on adjusting arm 21 drives threaded bushing 32 to rotate through reduction motor 31, so that connecting rod 33 rotates a certain distance in threaded bushing 32. Connecting part 411 is released by washers 34 on both sides, and can rotate on connecting rod 33 and flexibly adjust angle. At this time, the reduction motor 31 is started again to drive threaded bushing 32 to rotate in the opposite direction, so that connecting rod 33 is screwed in again. At the same time, the washers 34 on both sides of connecting part 411 are pushed to abut against each other to lock the position of connecting part 411. Then, the electric telescopic rod 44 is used to push the straightening plate 43. When the straightening plate 43 slides, it will drive the tooth groove 430 to move, thereby driving the gear 412 that meshes with it to rotate. When the gear 412 rotates, it will also move the toothed belt 6 that meshes with it synchronously. The relative or opposite movement of the two toothed belts 6 will push the clamping wing 42 to clamp and release the sapphire shaped part. After the sapphire is fixed and clamped onto the machining mold, the rotary motor 5 is started to drive the concave mold 51 or the convex mold 52 to rotate, so as to achieve uniform chamfering.
