[0002] Lens lenses play a vital role in the fields of photography and optics. Lens lenses are usually made of a variety of materials, such as glass, resin, etc. Glass lenses have higher optical performance and stability, but are relatively heavy, while resin lenses are lighter and less likely to break.

[0003] For example, the Chinese patent with publication number CN212713259U discloses a lens cutting device for optical lens production. The lens cutting device for optical lens production includes: a placement table; two support columns, both of which are fixedly mounted on the top of the placement table; a cross column, the cross column is fixedly mounted on the top of the two support columns; two hydraulic push rods, both of which are fixedly mounted on the bottom of the cross column; a lifting column, the lifting column is fixedly mounted on the output rods of the two hydraulic push rods; a first cavity, the first cavity is opened on the lifting column; a first motor, the first motor is fixedly mounted in the first cavity; a first slide groove, the first slide groove is opened at the bottom of the lifting column; a first screw, the first screw is rotatably mounted in the first slide groove. The lens cutting device for optical lens production provided by the utility model has the advantages of being easy to use, being able to cut circular lenses, and being able to adjust the cutting diameter.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: when adjusting the lens cutting diameter, this device cannot accurately adjust the lens cutting diameter, resulting in the cut lens diameter not being accurate enough. In addition, when cutting the lens, debris will be generated, and the debris will remain on the lens and the table, requiring personnel to perform secondary cleaning, which is troublesome. In view of this, we propose a lens cutting device for lens production. Utility Model Content

At the same time, the personnel can observe the scale lines and the arrows on the two sliding blocks with their eyes, so as to accurately control the distance between the two sliding blocks and the two cutting saws, and ensure that the diameter of the lens after cutting can be accurately controlled. Then the personnel can start the hydraulic cylinder, and the output end of the hydraulic cylinder will drive the rectangular block to move downward, and the downward movement of the rectangular block will drive the two sliding blocks and the two cutting saws to move downward. At this time, the fixed component is set up, and the fixed component can fix the lens. Then the personnel can start the two cutting saws and the motor, and the saw blades of the two cutting saws can rotate to cut the lens. The output shaft of the motor will drive the hydraulic cylinder and the rectangular block to rotate, and the rotation of the rectangular block will drive the two sliding blocks and the two cutting saws to rotate. The rotation of the two cutting saws can perform rotational cutting on the lens, and ensure that the cut lens is round.

[0013] Through the set water pump, personnel can start the water pump while cutting. The water pump can pump out the water at the bottom of the water tank and transport it to the water pipe. The water in the water pipe will be sprayed out through the extension pipe. At this time, the personnel can adjust the water outlet direction of the extension pipe to ensure that the water outlet direction of the extension pipe can be directly facing the cutting position of the lens, to ensure that the lens can be rinsed by the water sprayed from the extension pipe when it is cut, so that the debris generated by the lens during cutting will be washed onto the mesh plate by the water sprayed from the extension pipe, and then flow into the mesh plate through several mesh holes on the mesh plate, and then will be filtered through the filter and flow into the bottom of the water tank again. At the same time, the water sprayed from the extension pipe can also cool the saw blades of the two cutting saws, thereby extending the service life of the cutting saws. After the cutting is completed, the personnel can pull out the filter from the base and clean the filter to ensure that the debris generated by the lens cutting can be cleaned, and no secondary cleaning is required.

[0021] In the technical solution, the hydraulic cylinder is started, and the output end of the hydraulic cylinder drives the rectangular block to move downward, and the downward movement of the rectangular block drives the two sliding blocks and the two cutting saws to move downward. At the same time, the downward movement of the rectangular block also drives the round tube to move downward, and the downward movement of the round tube drives the extrusion rod and the extrusion plate to move downward, until the rubber pad 2 at the bottom of the extrusion plate contacts the top of the lens, and the round tube continues to move downward to squeeze the spring to contract. Under the action of the spring rebound force, the spring squeezes the extrusion rod, so that the extrusion plate and the rubber pad 2 on the extrusion rod are firmly squeezed on the top of the lens, and then the cutting blades of the two cutting saws contact To the lens, since the bottom of the rubber pad 2 is lower than the bottom of the cutting saw, the rubber pad 2 will contact the lens before the cutting saw, and then the personnel can start the two cutting saws and the motor. The saw blades of the two cutting saws can rotate to cut the lens, and the output shaft of the motor will drive the hydraulic cylinder and the rectangular block to rotate. The rotation of the rectangular block will drive the two sliding blocks and the two cutting saws to rotate. The rotation of the two cutting saws can rotate and cut the lens.

[0073] It is worth noting that the extension tube 24 involved in the utility model adopts the faucet extender with the product model P06B-YSG023 produced by Kabe Technology Co., Ltd. The extension tube 24 involved in the utility model is a prior art, which can be fully realized by those skilled in the art. Needless to say, the content of the protection of the utility model does not involve the improvement of the structure and working principle of the extension tube 24.

[0074] Working principle: when in use, the personnel can place the lens to be cut on the rubber pad 15, and then the personnel can turn the knob 14. The rotation of the knob 14 will drive the bidirectional threaded rod 13 to rotate. Under the action of the thread, the rotation of the bidirectional threaded rod 13 will drive the two sliding blocks 11 to approach each other. The two sliding blocks 11 approaching each other will drive the two cutting saws 12 to approach each other. At the same time, the personnel can observe the scale line 20 and the arrows on the two sliding blocks 11 with their eyes, so as to accurately control the distance between the two sliding blocks 11 and the two cutting saws 12 to ensure that the diameter of the lens after cutting can be accurately controlled. Then the personnel can start the hydraulic cylinder 8, and the output end of the hydraulic cylinder 8 will drive the rectangular block 9 to move downward. The downward movement of the rectangular block 9 will drive the two sliding blocks 11 and the two cutting saws 12 to move downward. At the same time, the downward movement of the rectangular block 9 will also drive the circular tube 15 to move downward. The downward movement of the circular tube 15 will drive the extrusion rod 16 and the extrusion plate 18 to move downward until the rubber pad 19 at the bottom of the extrusion plate 18 hits. When at the top of the lens, the circular tube 15 continues to move downward to squeeze the spring 17 to shrink. Under the action of the rebound force of the spring 17, the spring 17 squeezes the squeezing rod 16, so that the squeezing plate 18 and the rubber pad 19 on the squeezing rod 16 are firmly squeezed on the top of the lens, and then the cutting knives of the two cutting saws 12 will contact the lens. Since the bottom of the rubber pad 19 is lower than the bottom of the cutting saw 12, the rubber pad 19 will contact the lens before the cutting saw 12. Then the personnel can start the two cutting saws 12 and the motor 7. The saw blades of the two cutting saws 12 can rotate to cut the lens. The output shaft of the motor 7 will drive the hydraulic cylinder 8 and the rectangular block 9 to rotate. The rotation of the rectangular block 9 will drive the two sliding blocks 11 and the two cutting saws 12 to rotate. The rotation of the two cutting saws 12 can rotate and cut the lens. At this time, under the action of friction, the rubber pad 19 on the squeezing plate 18 will press against the top of the lens, and the squeezing rod 16 will rotate on the squeezing plate 18 to ensure that the cut lens is round.

[0075] During cutting, the personnel can start the water pump 22, which can pump out the water at the bottom of the water storage tank 2 and transport it to the water pipe 23. The water in the water pipe 23 will be sprayed out through the extension pipe 24. At this time, the personnel can adjust the water outlet direction of the extension pipe 24 to ensure that the water outlet direction of the extension pipe 24 can be directly facing the cutting position of the lens, to ensure that when the lens is cut, the water sprayed from the extension pipe 24 can rinse the lens, so that the debris generated by the lens during cutting will be washed onto the mesh plate 3 by the water sprayed from the extension pipe 24, and then flow into the mesh plate 3 through several mesh holes on the mesh plate 3, and then will be filtered by the filter net 21 and flow into the bottom of the water storage tank 2 again. At the same time, the water sprayed from the extension pipe 24 can also cool the saw blades of the two cutting saws 12, thereby extending the service life of the cutting saw 12. After the cutting is completed, the personnel can pull the filter net 21 out of the base 1 and clean the filter net 21 to ensure that the debris generated by the lens cutting can be cleaned, and the personnel do not need to perform secondary cleaning.
