[0002] A microscope is a common precision instrument. Composed of a lens and a combination of lenses, it is primarily used to magnify tiny objects so they can be seen by the naked eye. Microscopes use lenses to magnify tiny objects, and the precision of the microscope determines its magnification. With the development of the times, electron microscopes have emerged, but they still rely on lenses. At the same time, to improve the accuracy of microscope use, the edges of the microscope lenses need to be thinned to meet the requirements of microscopes of different specifications.

[0008] Preferably, the rotating assembly includes a U-shaped bracket, a motor, a transmission plate, a transmission chain, a telescopic rod and a fixed shaft, and the U-shaped bracket is fixed to the outer walls on both sides of the chassis by bolts.

[0009] Furthermore: the motor is fixed to one side of the bottom of the U-shaped bracket through a support plate, and the fixed shaft is connected to one side of the U-shaped bracket through a thread, the transmission disc close to the motor side is connected to the output end of the motor through a thread, and the transmission disc close to the U-shaped bracket side is connected to the circumference of the fixed shaft through a bearing.

[0010] On the basis of the above solution: the transmission chain is sleeved on the circumference of the two transmission discs, and the two telescopic rods are connected to the circumference of the transmission discs through threads.

[0011] A better solution among the above solutions is: a mounting groove is opened on one side of the back of the rotating wheel, and the extension rod ends of the two telescopic rods are connected to the inner wall of the mounting groove through threads.

[0012] As a further solution of the present invention: the telescopic assembly includes a main gear, a secondary gear, a fixed plate, a guide rod, a screw, a threaded groove and a fixed ring, and the main gear is connected to the lower side of the adjusting disk through a guide shaft, and a guide hole is opened on the inner wall of one side of the U-shaped bracket.

[0013] At the same time, a bearing is clamped in the guide hole, the screw is inserted into the inner ring of the bearing, the secondary gear is connected to one end of the screw through a thread, the main gear and the secondary gear are engaged with each other, and the two fixing plates are fixed to the circumference of one side of the fixed shaft by bolts.

[0014] As a preferred embodiment of the present invention: the fixing ring is fixed to the opposite end of the two fixing plates by bolts, sliding grooves are opened on both inner sides of the fixing ring, and the two sides of the guide rod are slidably connected in the two sliding grooves, one end of the guide rod is connected to the central inner wall of the installation groove through a bearing, and the inner wall of the guide rod is opened with a threaded groove, and the threaded groove is adapted to the screw rod.

[0015] At the same time, a mounting plate is fixed to the outer wall of one side of the chassis by bolts, and a rack plate is slidably connected inside the mounting plate. The inner wall of the back side of the chassis is rotatably connected to the first linkage gear through a connecting shaft, and the first linkage gear and the secondary gear are engaged with each other.

[0017] The beneficial effects of the present invention are:

[0018] 1. This optical processing microscope lens edge thinning processing device, when working, fixes one surface of the lens to one side of the rotating wheel by a suction cup, and then starts the rotating pushing mechanism in the chassis. At this time, the rotating component drives the rotating wheel to rotate, and the rotating wheel drives the lens to rotate. In this process, the telescopic component is driven to work by rotating the adjustment dial, so that the rotating wheel can be horizontally displaced in the rotating state. At the same time, the telescopic bottom plate is moved to drive the limit plate on its top to move, so that the lens contacts the arc-shaped frosting plate on one side of the limit plate, completing the edge thinning of the microscope lens. Therefore, it not only meets the requirements of thinning the edges of lenses of different thicknesses, but also ensures the efficiency and quality of lens edge thinning.

[0019] 2. This optical processing microscope lens edge thinning processing device, when the adjustment disk rotates, drives the main gear to rotate, and the rotating main gear drives the secondary gear to rotate, and causes the screw to rotate. The rotating screw adapts to the guide rod through the thread groove, thereby driving the guide rod to move. At this time, the guide rod slides in the fixed ring and pushes the rotating wheel, and at the same time, the telescopic rods on both sides of the rotating wheel are also extended, thereby playing a role of horizontally pushing the rotating wheel, ensuring the flexibility of the lens edge thinning work and improving the practicality of the device.

[0020] 3. This optical processing microscope lens edge thinning device starts the motor, which drives the transmission disk to rotate. The rotating transmission disk drives another transmission disk to rotate through the transmission chain. This transmission disk drives the rotation of the rotating wheel connected to it via the telescopic rod. This drives the rotation of the lens on one side of the rotating wheel, ensuring the stability of the lens' rotation on the rotating wheel side.

[0021] 4. In an optical processing microscope lens edge thinning device, when the secondary gear is driven to rotate by the main gear, the first linkage gear also rotates accordingly, and at the same time, the second linkage gear also rotates synchronously. During this period, the rack plate is driven by the second linkage gear to move horizontally, so that the clamping plate at the end of the sleeve plate is just inserted into the clamping groove on the side of the baffle. When the lens located on the circumference of the rotating wheel is undergoing edge thinning, the distance sensor can effectively measure the thickness of the initial lens and the completed lens, thereby meeting the thinning requirements of different lenses. At the same time, by rotating the adjustment dial, not only the rotational displacement of the rotating wheel is completed, but also the linear displacement of the distance sensor is synchronously completed, thereby improving the efficiency and quality of lens polishing.

[0033] Example 1:

[0034] An optical processing microscope lens edge thinning device, such as Figure 1-6 As shown, it includes a chassis 1, a telescopic bottom plate 2 is fixed to the outer wall of one side of the bottom of the chassis 1 by bolts, and a limit plate 3 is provided on the outside of one side of each telescopic bottom plate 2, and a baffle 6 is welded to the side outer wall of the limit plate 3, and an arc-shaped frosted plate 7 is provided on the side of the limit plate 3 close to the baffle 6. A rotating pushing mechanism is provided in the chassis 1, and a runner 4 is provided at the end of the rotating pushing mechanism, and suction cups 18 are equidistantly distributed on the outer wall of one side of the runner 4. The rotating pushing mechanism includes a rotating component and a telescopic component, and the telescopic component is arranged inside the rotating component, and the driving end of the telescopic component is connected to the adjusting disk 5 by a thread;

[0035] During operation, one surface of the lens is fixed to one side of the rotating wheel 4 by the suction cup 18, and then the rotating pushing mechanism in the chassis is started. At this time, the rotating component drives the rotating wheel 4 to rotate, and the rotating rotating wheel 4 drives the lens to rotate. In this process, the telescopic component is driven to work by rotating the adjusting disk 5, so that the rotating wheel 4 can be horizontally displaced in the rotating state. At the same time, the limiting plate 3 on the top of the telescopic bottom plate 2 is driven to move, so that the lens contacts the arc-shaped frosting plate 7 on one side of the limiting plate 3, completing the edge thinning of the microscope lens. In this way, it not only meets the requirements of edge thinning of lenses of different thicknesses, but also ensures the efficiency and quality of lens edge thinning.

[0036] In order to promote the lens to rotate stably on one side of the wheel 4; Figure 4-5As shown, the rotating assembly includes a U-shaped bracket 9, a motor 12, a transmission disc 13, a transmission chain 14, a telescopic rod 15 and a fixed shaft 20, and the U-shaped bracket 9 is fixed to the outer walls on both sides of the inside of the chassis 1 by bolts, the motor 12 is fixed to one side of the bottom of the U-shaped bracket 9 by a support plate, and the fixed shaft 20 is connected to one side of the U-shaped bracket 9 by a thread, the transmission disc 13 close to the side of the motor 12 is connected to the output end of the motor 12 by a thread, the transmission disc 13 close to the side of the U-shaped bracket 9 is connected to the circumference of the fixed shaft 20 by a bearing, and the transmission chain 14 is sleeved on the circumference of the two transmission discs 13, the two telescopic rods 15 are connected to the circumference of the transmission disc 13 by a thread, and a mounting groove 8 is opened on one side of the back of the rotating wheel 4, and the extension rod ends of the two telescopic rods 15 are connected to the inner wall of the mounting groove 8 by a thread;

[0037] During operation, the motor 12 is started, and the motor 12 drives the transmission disc 13 to rotate. The rotating transmission disc 13 drives another transmission disc 13 to rotate through the transmission chain 14. This transmission disc 13 drives the rotating wheel 4 connected to it through the telescopic rod 15 to rotate, thereby driving the rotation of the lens on one side of the rotating wheel 4, ensuring the stability of the lens rotating on one side of the rotating wheel 4.

[0038] When this embodiment is in use, one surface of the lens is fixed to one side of the rotating wheel 4 by means of the suction cup 18. Then, the motor 12 is started, and the motor 12 drives the transmission disc 13 to rotate. The rotating transmission disc 13 drives another transmission disc 13 to rotate via the transmission chain 14. This transmission disc 13 drives the rotating wheel 4 connected thereto via the telescopic rod 15 to rotate, thereby driving the rotation of the lens on one side of the rotating wheel 4. In this process, the telescopic assembly is driven to work by rotating the adjustment disc 5, so that the rotating wheel 4 can be horizontally displaced while rotating. At the same time, the limiting plate 3 on the top of the telescopic bottom plate 2 is driven to move, so that the lens contacts the arc-shaped frosting plate 7 on one side of the limiting plate 3, completing the edge thinning of the microscope lens.

[0041] When the adjusting disk 5 rotates, it drives the main gear 10 to rotate, and the rotating main gear 10 drives the secondary gear 11 to rotate, and causes the screw 19 to rotate. The rotating screw 19 adapts to the guide rod 17 through the thread groove 21, thereby driving the guide rod 17 to move. At this time, the guide rod 17 slides in the fixing ring 22 and pushes the runner 4. At the same time, the telescopic rods 15 on both sides of the runner 4 are also extended, thereby playing a role in horizontally pushing the rotating runner 4, ensuring the flexibility of the lens edge thinning work and improving the practicality of the device.

[0042] Example 3:

[0043] An optical processing microscope lens edge thinning device, such as Figure 1-5 As shown, in order to ensure the quality of lens edge thinning, a mounting plate 101 is fixed to the outer wall of one side of the chassis 1 by bolts, and a rack plate 113 is slidably connected to the mounting plate 101. The back inner wall of the chassis 1 is rotatably connected to a first linkage gear 111 via a connecting shaft, and the first linkage gear 111 is meshed with the secondary gear 11;

[0044] The bottom outer wall of the U-shaped bracket 9 on the side close to the first linkage gear 111 is fixed with a support plate by bolts, and the top outer wall of the support plate is rotatably connected to the second linkage gear 112 through a rotating shaft, the second linkage gear 112 and the first linkage gear 111 are meshed with each other, and the second linkage gear 112 and the rack plate 113 are meshed with each other, and one end of the rack plate 113 is slidably connected to a socket plate 114, and a slot 301 is opened on the outer wall of one side of the baffle 6 close to the socket plate 114, and a clamping plate 115 is fixed to the outer wall of one side of the end of the socket plate 114 by bolts, and a distance measuring sensor is fixed to the outer wall of the clamping plate 115 on the side close to the runner 4 by bolts, and the slot 301 is adapted to the clamping plate 115;

[0045] When the secondary gear 11 is driven to rotate by the main gear 10, the first linkage gear 111 also rotates accordingly. At the same time, the second linkage gear 112 also rotates synchronously. In the meantime, the rack plate 113 is driven by the second linkage gear 112 to perform horizontal displacement, so that the clamping plate 115 at the end of the sleeve plate 114 is just clamped into the clamping groove 301 on the side of the baffle 6. When the lens located on the circumference of the rotating wheel 4 is undergoing edge thinning, the distance sensor can effectively measure the thickness of the initial lens and the completed lens, thereby meeting the thinning requirements of different lenses.
