Description

Technical Field

[0001] This utility model relates to the field of lens processing technology, specifically to a lens edge grinding machine. Background Technology

[0002] Lenses are transparent materials with one or more curved surfaces, made of optical materials such as glass or resin. After being polished, they are often assembled with eyeglass frames to make eyeglasses, used to correct the user's vision and obtain a clear field of vision. During the lens processing, some sharp edges often appear on the edges. These sharp edges will prevent the lens from being used directly and need to be polished off with a polishing machine.

[0003] According to the lens edge grinding machine disclosed in patent number CN 220592597 U, a height-adjustable and angle-adjustable grinding machine is installed at the top inside the machine housing. The installed lens is rotatable, so that the lens can be ground from all directions. However, the grinding machine can only perform coarse grinding on the lens, which is a single function. The lens after coarse grinding still needs to be removed for further polishing, which makes the lens processing time-consuming and inefficient. Therefore, we propose a lens edge grinding machine.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lens edge grinding machine, comprising a frame, a controller being provided at the top of the frame, and U-shaped mounting brackets being fixedly connected to the top and bottom of the inner wall of the frame, with a grinding machine and a polishing machine respectively passing through the two mounting brackets via rotating shafts. A linear module is arranged vertically inside the frame, and support plates are symmetrically fixed to both ends of the lifting block of the linear module. A transmission rod is rotatably connected between the two support plates, and a lens positioning mechanism is symmetrically arranged on the outer side of the transmission rod.

Cylinders are installed at the bottom ends of the corresponding side walls of the U-shaped plates. The piston rod ends of the two cylinders are fixedly connected to the bottom ends of the first mounting plate and the second mounting plate, respectively. The ends of the first mounting plate and the second mounting plate are located outside the U-shaped plate. The top ends of the first mounting plate and the second mounting plate on one side of the U-shaped plate are rotatably connected to a support rod through a bearing.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a lens processing edge polishing machine, including a frame 1, a controller 2 is provided on the top of the frame 1, and U-shaped mounting brackets 3 are fixedly connected to the top and bottom of the inner wall of the frame 1. A polishing machine 4 and a grinding machine 6 are respectively connected to the rotating shaft in the two mounting brackets 3. A linear module 7 is arranged vertically in the frame 1, and support plates 8 are symmetrically fixed to both ends of the lifting block of the linear module 7. A transmission rod 9 is rotatably connected between the two support plates 8, and a lens positioning mechanism 10 is symmetrically arranged on the outer side of the transmission rod 9.

[0022] It should be noted that both the grinding machine 4 and the polishing machine 6 are mounted on the frame 1, enabling grinding and polishing of the lens and improving the processing efficiency of the lens. The linear module 7 facilitates the control of the lifting and lowering of the positioned lens, making it easy to move the lens to the grinding machine 4 or the polishing machine 6. The linear module 7 is a combination of a lead screw, a slide bar, and a servo motor. The servo motor drives the lead screw to rotate. One end of the lifting block is threaded on the outside of the lead screw, and the other end is slidably set on the outside of the slide bar, so that the lifting block can be lifted and lowered smoothly.

[0023] Please see Figure 3The lens positioning mechanism 10 includes a mounting base 11. The mounting base 11 is fixedly connected to the middle of the transmission rod 9. U-shaped plates 12 are symmetrically arranged at the top and bottom of the mounting base 11. A first mounting plate 14 and a second mounting plate 15 are symmetrically arranged inside the U-shaped plate 12. Cylinders 13 are installed at the bottom ends of the corresponding side walls of the U-shaped plate 12. The piston rod ends of the two cylinders 13 are fixedly connected to the bottom ends of the first mounting plate 14 and the second mounting plate 15, respectively. The ends of the first mounting plate 14 and the second mounting plate 15 are located outside the U-shaped plate 12. The top ends of the first mounting plate 14 and the second mounting plate 15 located on one side of the U-shaped plate 12 are rotatably connected to a support rod 16 through a bearing. The end of the support rod 16 slides through the U-shaped plate 12. A suction cup 17 is installed at the end of the support rod 16.

[0024] It should be noted that the two lens positioning mechanisms 10 can position two lenses respectively. The controller 2 can control the operation of the cylinders 13 on the two lens positioning mechanisms 10 respectively. When the polished lens needs to be removed, the operator holds the lens and the controller 2 can control the piston rod of the lower cylinder 13 to retract. At the same time, a new lens that needs to be polished can be replaced. After the upper lens is polished, the two lens positioning mechanisms 10 are rotated to interchange their positions, which facilitates the polishing of the polished lens.

[0025] Please see Figure 3 A second motor 18 is fixedly installed on the side wall of the second mounting plate 15, and the end of the output shaft of the second motor 18 passes through the second mounting plate 15 and is fixedly connected to the support rod 16. A drive motor 19 is fixedly installed on the side wall of the support plate 8, and the end of the output shaft of the drive motor 19 passes through the support plate 8 and is fixedly connected to the transmission rod 9.

[0026] It should be noted that, when using this utility model, the lens to be polished is placed between the two suction cups 17 on the upper part of the transmission rod 9. The controller 2 controls the two cylinders 13 to work, pushing the first mounting plate 14 and the second mounting plate 15 to move closer at the same time, so that the two suction cups 17 adsorb and fix the lens. The linear module 7 controls the fixed lens to move upward, and the polishing machine 4 polishes the edge of the lens. The second motor 18 can be controlled to drive the lens to rotate. The first motor 5 can drive the polishing machine 4 to rotate at a corresponding angle, so that the polishing machine 4 can polish the outer edge of the lens in all directions. After the lens is coarsely polished, the drive motor 19 can be controlled to work, so that the transmission rod 9 rotates 180 degrees, so that the roughly polished lens is directly below. The linear module 7 can control the support plate 8 to move down to the polishing machine 6. The first motor 5 at the polishing machine 6 can drive the polishing machine 6 to rotate at a corresponding angle. In conjunction with the rotation of the lens, the lens can be finely polished.

[0027] Please see Figure 1 The rack 1 is located on one side of the controller 2 and has a storage drawer 20.

[0028] It should be noted that the storage drawer 20 is designed for storing spare items.

[0029] Please see Figure 1 The top of the frame 1, located on one side of the controller 2, has an opening for easy operation, and a door frame with an inner glass door is hinged inside the opening.

[0030] It should be noted that the glass door facilitates observation of the internal grinding and polishing of the lenses, while also keeping the interior of the frame 1 sealed to prevent internal debris from flying out.

[0031] Please see Figure 2 The polishing machine 6 is located directly below the grinding machine 4, and the middle of the area between the two suction cups 17 is in the same vertical line as the first motor 5 and the polishing machine 6.

[0032] It should be noted that the polishing machine 6 and the grinding machine 4 are located in the upper and lower parts of the frame 1, respectively. When the lens adsorbed by the two suction cups 17 moves upward, it can be ground by the grinding machine 4. When the lens moves downward, it can be polished by the polishing machine 6.

[0033] Please see Figure 1 Rubber support pads are provided at the four corners of the bottom of frame 1.

[0034] It should be noted that the rubber support pads enhance the stability of frame 1.

[0035] Please see Figure 2 Each of the two mounting brackets 3 has a No. 1 motor 5 mounted on its side wall, and the output shaft ends of the two No. 1 motors 5 are respectively fixedly connected to the rotating shafts on the grinder 4 and the polisher 6.

[0036] It should be noted that the two No. 1 motors 5 can drive the grinding machine 4 and the polishing machine 6 to rotate at a certain angle, so as to achieve better grinding and polishing of the lens.
