Description

Technical Field

[0001] The utility model belongs to the technical field of polishing equipment, in particular to an optical lens polishing device. Background Art

[0002] Polishing is a process that uses mechanical, chemical, or electrochemical methods to reduce the surface roughness of a workpiece to achieve a bright, smooth surface. Polishing is a modification of the workpiece surface using polishing tools and abrasive particles or other polishing media. Polishing does not improve the dimensional or geometric accuracy of the workpiece, but rather aims to achieve a smooth or mirror-like finish. It is also sometimes used to eliminate gloss (matte).

[0003] Most existing optical lens polishing devices can only polish a single lens at a time, and after polishing one side, the optical lens needs to be manually flipped over before polishing the other side of the lens. This greatly reduces the polishing efficiency of the optical lens and greatly increases the labor intensity of the workers. Therefore, an optical lens polishing device is urgently needed to solve this problem. Utility Model Content

[0004] The purpose of the utility model is to provide an optical lens polishing device to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an optical lens polishing device, comprising a conveyor belt for conveying optical lenses and a fixing frame for installing the polishing device, the top surface of the conveyor belt is bonded with a rubber plate, the top surface of the rubber plate is symmetrically bonded with a fixing plate, both fixing plates are longitudinally penetrated with a strip hole, an electric telescopic rod is fixedly installed at the bottom of the strip hole, the telescopic end of the electric telescopic rod is fixedly connected to a push plate, the top surface of the push plate is welded with a push spring, the top surface of the push spring is welded with a slider, the opposite sides of the two sliders are rotatably connected to a rotating rod, a motor is bolted to the side of one of the sliders away from the rotating rod, and the end of the motor's rotating shaft is fixedly connected to one of the rotating rods;

[0006] A fixing ring is fixedly connected between the two rotating rods, a limiting cylinder is symmetrically bolted to the inner wall of the fixing ring, a connecting rod is slidably connected inside the limiting cylinder, a spring is fixedly connected inside the limiting cylinder, the end of the spring is fixedly connected to the connecting rod, and the ends of the two connecting rods are fixedly connected with an arc plate for clamping optical lenses.

[0007] Preferably, the inner wall of the limiting cylinder is symmetrically provided with limiting grooves, and the outer wall of the connecting rod is symmetrically fixedly connected with limiting blocks.

[0008] Preferably, the two limiting blocks fixedly connected to the outer wall of the connecting rod are respectively slidably connected to the inside of two limiting grooves opened on the inner wall of the limiting cylinder.

[0009] Preferably, the side walls of the two sliding blocks are symmetrically fixedly connected with two strip blocks, and the inner walls of the two strip holes are symmetrically provided with two vertical grooves.

[0010] Preferably, the two strip blocks fixedly connected to the outer wall of the slider are respectively slidably connected to the inside of two vertical grooves opened on the inner wall of the strip hole.

[0011] Preferably, a damping rod is fixedly installed between the push plate and the slider, and the damping rod is slidably sleeved inside the push spring.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are:

[0013] The optical lens polishing device places the lens to be polished between two curved plates and pushes the curved plates through two springs to tighten the lens. Then, an electric telescopic rod is used to push the optical lens toward the polishing mechanism to polish one side of the optical lens. At the same time, a conveyor belt is started to continuously polish the optical lens, thereby improving the polishing efficiency of the lens.

[0014] This optical lens polishing device reverses the activation of an electric telescopic rod to drive the push plate, push spring, slider, and fixed ring downward, thereby moving the optical lens away from the polishing mechanism. The motor is then activated to rotate the rotating rod and the fixed ring between the two rotating rods, which in turn drives the lens engaged within the fixed ring. When the lens rotates 180 degrees, the motor automatically stops, completing the flipping of the lens. The electric telescopic rod is then activated again to push the lens toward the polishing mechanism again, thereby polishing the other side of the lens. Compared to existing technologies, this device can achieve continuous polishing of optical lenses while also automatically flipping them, greatly improving the polishing efficiency of the lenses.

[0023] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.

[0024] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0025] The connection method can be bonding, welding, bolt connection, etc., which shall be based on actual needs.

[0026] like Figures 1 to 5 The main structure of an optical lens polishing device shown in the figure is a conveyor belt 1 for conveying optical lenses and a fixed frame 2 for installing a polishing mechanism. The polishing mechanism here is common knowledge, so it is not repeated in the appendix of the specification. Figure 2 ;

[0027] A rubber sheet 4 is bonded to the top surface of the conveyor belt 1, and a fixing plate 5 is symmetrically bonded to the top surface of the rubber sheet 4. Thanks to the arrangement of the rubber sheet 4, when the rubber sheet 4 moves to the end of the conveyor belt 1, the conveyor belt 1 will bend along with the driving roller. Therefore, thanks to the soft material of the rubber sheet 4, it will bend and deform along with the conveyor belt 1 without affecting the structure of the top surface of the rubber sheet 4.

[0028] The two fixing plates 5 are both longitudinally penetrated with a strip hole 6, and an electric telescopic rod 7 is fixedly installed at the bottom of the strip hole 6. The telescopic end of the electric telescopic rod 7 is fixedly connected to a push plate 8, and a push spring 9 is welded to the top surface of the push plate 8. A slider 10 is welded to the top surface of the push spring 9. The opposite sides of the two sliders 10 are rotatably connected to a rotating rod 11. Thanks to the structures of the push plate 8, push spring 9, etc., when the optical lens contacts the polishing mechanism, the two push springs 9 buffer the optical lens, thereby preventing the optical lens and the polishing mechanism from being squeezed too hard;

[0029] A motor 17 is bolted to one side of one of the sliders 10 away from the rotating rod 11, and the end of the rotating shaft of the motor 17 is fixedly connected to one of the rotating rods 11. The motor 17 drives the rotating rod 11 to which the end of the rotating shaft is fixedly connected to rotate, and then drives the fixing ring 12 and the optical lens clamped inside the fixing ring 12 to rotate through the rotating rod 11. When the optical lens is rotated 180°, the motor 17 will automatically stop, thereby completing the flipping of the optical lens;

[0030] A fixing ring 12 is fixedly connected between the two rotating rods 11, and a limiting cylinder 14 is symmetrically bolted to the inner wall of the fixing ring 12. A connecting rod 15 is slidably connected to the limiting cylinder 14. A spring 13 is fixedly connected to the inside of the limiting cylinder 14, and the end of the spring 13 is fixedly connected to the connecting rod 15. The ends of the two connecting rods 15 are fixedly connected to an arc plate 16 for clamping the optical lens. The optical lens to be polished is placed between the two arc plates 16, and then the spring 13 fixedly installed between the arc plate 16 and the inner wall of the fixing ring 12 pushes the connecting rod 15 fixedly connected to it and the arc plate 16 fixedly connected to the end of the connecting rod 15 to extrude and limit the optical lens, thereby completing the installation of the lens.

[0031] The inner wall of the limiting cylinder 14 is symmetrically provided with limiting grooves, and the outer wall of the connecting rod 15 is symmetrically fixedly connected with limiting blocks 18. The two limiting blocks 18 fixedly connected to the outer wall of the connecting rod 15 are respectively slidably connected to the inside of the two limiting grooves provided on the inner wall of the limiting cylinder 14. Thanks to the two limiting blocks 18 fixedly connected to the outer wall of the connecting rod 15 being respectively slidably connected to the inside of the two limiting grooves provided on the inner wall of the limiting cylinder 14, the sliding direction of the connecting rod 15 can be limited.

[0032] The side walls of the two sliders 10 are symmetrically fixed with two strip blocks 19, and the inner walls of the two strip holes 6 are symmetrically opened with two vertical grooves. The two strip blocks 19 fixedly connected to the outer walls of the sliders 10 are respectively slidably connected to the inside of the two vertical grooves opened on the inner walls of the strip holes 6. Thanks to the two strip blocks 19 fixedly connected to the outer walls of the sliders 10 being respectively slidably connected to the two vertical grooves opened on the inner walls of the strip holes 6, the sliding direction of the slider 10 can be limited while further improving the stability of the slider 10 during sliding.

[0033] A damping rod 3 is fixedly installed between the push plate 8 and the slider 10. The damping rod 3 is slidably sleeved inside the push spring 9. Thanks to the setting of the damping rod 3, the vibration generated by the optical lens during polishing can be prevented from being transmitted to the push spring 9, thereby causing the push spring 9 to vibrate and affecting the stability of the optical lens.

[0034] How it works

[0035] When using the optical lens polishing device, first place the optical lens to be polished between the two curved plates 16, then push the connecting rod 15 fixedly connected to it and the curved plate 16 fixedly connected to the end of the connecting rod 15 through the spring 13 fixedly installed between the curved plate 16 and the inner wall of the fixing ring 12 to squeeze and limit the optical lens, thereby completing the installation of the lens, and then start the conveyor belt 1 to drive the rubber plate 4, the fixing plate 5 and the optical lens to move to the polishing mechanism in the fixed frame 2 and polish one side of the lens. When one side of the lens needs to be turned over after polishing, the electric telescopic rod 7 is started to drive the optical lens downward away from the polishing machine. The motor 17 is then started, which is fixedly mounted on the side wall of one of the sliders 10. The motor 17 drives the rotating rod 11 fixedly connected to the end of its rotating shaft to rotate. The rotating rod 11 then drives the fixing ring 12 and the optical lens clamped inside the fixing ring 12 to rotate. When the optical lens is rotated 180°, the motor 17 will stop automatically, thereby completing the flipping of the optical lens. The electric telescopic rod 7 is then started again to push the optical lens upward. At the same time, thanks to the push plate 8, push spring 9 and other structures, when the optical lens contacts the polishing mechanism, the two push springs 9 are used to buffer the optical lens, thereby preventing the optical lens and the polishing mechanism from being squeezed too hard.
