Abstract
Description
Technical Field
[0001] This invention belongs to the field of optical glass surface pressing technology, and more specifically, relates to a glass pressing device. Background Technology
[0002] Optical glass refers to glass that can alter the direction of light propagation and change the relative spectral distribution of ultraviolet, visible, or infrared light. In a narrow sense, optical glass refers to colorless optical glass; in a broader sense, it also includes colored optical glass, laser glass, quartz optical glass, radiation-resistant glass, ultraviolet-infrared optical glass, fiber optic glass, acousto-optic glass, magneto-optic glass, and photochromic glass. Optical glass is used to manufacture lenses, prisms, mirrors, and windows in optical instruments. Components made of optical glass are key elements in optical instruments.
[0003] When producing high-viscosity optical glass in large quantities, the high viscosity can easily lead to excessively large radius (r-angle) between the glass surface and the sidewalls during forming. This results in insufficient width of the surface slices and waste in subsequent sheet production, and also causes significant waste for downstream customers. Traditionally, excessive r-angles in optical glass production are reduced as much as possible by surface rolling or surface forming, but the actual reduction is limited and still results in considerable waste. Summary of the Invention
[0004] The purpose of this invention is to provide a glass pressing device that can minimize the r-angle of optical glass.
[0005] The technical solution adopted by this invention is as follows: A glass pressing device includes a base and cylinders disposed at both ends inside the base. The pressing device includes:
[0006] A pressing mechanism, located at the top of the cylinder, is used to press and tap the surface of the optical glass to reduce the r-angle of the optical glass surface.
[0007] An adjustment mechanism, located inside the base, is used to adjust the distance between the two cylinders;
[0008] An indicator, disposed on the side wall of the cylinder, is used to indicate the accurate data of the distance between the two cylinders;
[0009] A support mechanism is provided inside the base, through which the optical glass is supported by a molding die. This support mechanism is used to buffer the descent speed of the pressure block and increase its service life.
[0010] The pressing mechanism includes a transmission rod, a support plate, a buffer section, and a pressing block. The transmission rod is movably connected inside the cylinder. The support plate is fixedly installed at one end of the transmission rod. The buffer section is fixedly installed on one side of the support plate. The pressing block is fixedly installed on one side of the buffer section. The pressing block is located at the top of the base.
[0011] Optionally, an air inlet and outlet pipe is fixedly installed at the cylinder connection end, the front and rear width of the pressure block is between 50-100mm, and the width ratio of the pressure block to the optical glass is between 0.4-0.8.
[0012] Optionally, the adjustment mechanism includes a protrusion, a threaded rod, and a first slider. There are two protrusions, which are respectively fixedly installed on one side of the base. The threaded rod is rotatably connected inside the protrusion. There are several first sliders, which are respectively fixedly installed on the side walls of the two cylinders. The first slider has a thread inside that matches the threaded rod.
[0013] Optionally, an adjusting rod is rotatably connected inside the base, a second transmission gear is fixedly installed at one end of the adjusting rod, and a first transmission gear is fixedly installed on the side wall of the threaded rod, the first transmission gear meshing with the second transmission gear.
[0014] Optionally, a second slider is fixedly installed on the side wall of the cylinder. Several second sliders are provided. A groove is opened inside each of the two protrusions. A guide rail is fixedly installed inside one of the grooves. The second slider is slidably connected to the side wall of the guide rail. The threaded rod is rotatably connected inside the other groove.
[0015] Optionally, the base sidewall is provided with a scale groove, and the indicator is matched with the scale groove.
[0016] Optionally, the support mechanism includes a first support plate, a movable plate, and a tension spring. The base has a groove inside, the movable plate matches the groove, and the movable plate is slidably connected inside the groove. The tension spring is fixedly installed between the inner wall of the groove and one side of the movable plate. The first support plate is fixedly installed on the top of the movable plate, and the first support plate is slidably connected inside the base through the movable plate.
[0017] Optionally, a buffer pad matching the first support plate is fixedly installed on the side wall of the cylinder.
[0018] Optionally, the support mechanism further includes a second support plate and a spring. The first support plate has a movable groove inside, the second support plate is slidably connected inside the movable groove, and the spring is fixedly installed between the movable groove and the bottom of the second support plate.
[0019] Optionally, a support pad is fixedly installed on the inner wall of the first support plate, and the second support plate is located between the first support plate and the support pad.
[0020] The technical effects achieved by this invention are as follows:
[0021] (1) This solution sets up a pressing mechanism. When in use, the cylinder is powered on and the equipment is started. The cylinder drives the transmission rod to move up and down at a certain speed. The transmission rod drives the pressure block to squeeze the glass surface, causing the optical glass to deform and move to both sides to fill the optical glass r angle and reduce it, thereby ensuring that the optical glass r angle can be reduced to the maximum extent.
[0022] (2) By setting a support mechanism, the two first support plates can be pulled towards the center of the base by setting a tension spring through the movable plate. The optical glass is supported by a forming mold to buffer the descent speed of the pressure block and increase its service life. By setting a buffer pad, the collision damage between the first support plate and the cylinder can be avoided. By setting a support pad, the second support plate can be prevented from tilting when moving in the movable groove. Since the second support plate slides in the movable groove, the second support plate will not affect the deformation of the optical glass during the pressing deformation process.
[0023] (3) By setting an adjustment mechanism, the rotation of the threaded rod can be controlled by rotating the adjustment rod, making it more convenient to control the rotation of the threaded rod. When the threaded rod rotates, the first slider moves on the side wall of the threaded rod. The distance between the two cylinders is adjusted by the movement of the first slider, so that the size of the pressed r angle can be adjusted according to the size of the optical glass.
[0024] (4) By opening a scale groove on the side wall of the base to cooperate with the indicator, the distance between the two cylinders can be adjusted more accurately;
[0025] (5) By setting a guide rail and a second slider, the cylinder can be made more stable during adjustment and movement. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0036] Please see Figure 1-6 The present invention provides a glass pressing device, comprising a base 1 and cylinders 2 disposed at both ends inside the base 1. The pressing device includes:
[0037] The pressing mechanism, located on top of cylinder 2, is used to press and tap the surface of the optical glass to reduce the r-angle of the optical glass surface;
[0038] An adjustment mechanism, located inside the base 1, is used to adjust the distance between the two cylinders 2;
[0039] Indicator 4, located on the side wall of cylinder 2, is used to indicate the accurate distance between the two cylinders 2;
[0040] A support mechanism is located inside the base 1. This support mechanism is used to buffer the descent speed of the pressure block and increase its service life.
[0041] The pressing mechanism includes a transmission rod 201, a support plate 202, a buffer section 203, and a pressing block 204. The transmission rod 201 is movably connected inside the cylinder 2. The support plate 202 is fixedly installed at one end of the transmission rod 201. The buffer section 203 is fixedly installed on one side of the support plate 202. The pressing block 204 is fixedly installed on one side of the buffer section 203. The pressing block 204 is located at the top of the base 1. The optical glass is placed in the support mechanism inside the base 1. When in use, the cylinder 2 is powered on and the equipment is started, so that the cylinder 2 drives the transmission rod 201 to move up and down at a certain speed. The transmission rod 201 drives the pressing block 204 to squeeze the glass surface, causing the optical glass to deform and move to both sides, filling the r-angle of the optical glass and reducing it, thereby ensuring that the r-angle of the optical glass can be reduced to the greatest extent.
[0042] In some embodiments, see Figure 1 , Figure 6 The cylinder 2 is fixedly connected to an air inlet / outlet pipe 205. The front-to-back width of the pressure block 204 is between 50-100mm, and the width ratio of the pressure block 204 to the optical glass is between 0.4-0.8. The support mechanism includes a first support plate 501, a movable plate 504, and a tension spring 505. The base 1 has a groove 503 inside, and the movable plate 504 matches the groove 503. The movable plate 504 is slidably connected inside the groove 503. The tension spring 505 is fixedly installed between the inner wall of the groove 503 and one side of the movable plate 504. The first support plate 501 is fixedly installed on the top of the movable plate 504 and is slidably connected inside the base 1 through the movable plate 504. A buffer pad 5 matching the first support plate 501 is fixedly installed on the side wall of the cylinder 2. By setting the air inlet / outlet pipe 205, it is possible to... By venting the cylinder 2, the two first support plates 501 can be pulled towards the center of the base 1 via the movable plate 504 through the tension spring 505. The optical glass is supported by the forming mold. This support mechanism is used to buffer the descent speed of the pressure block and increase its service life. The buffer pad 5 is set to prevent collision damage between the first support plate 501 and the cylinder 2. By keeping the front and rear width of the pressure block 204 between 50-100mm, the support mechanism ensures that the optical glass will not be squeezed forward and backward but will be pushed to both sides. When a certain high viscosity optical glass was actually tested on the production line, it was found that the r-angle of the optical glass was maintained at about 9mm when no equipment for reducing the r-angle was used. After using some rolling and forming equipment, it was found that it was best to reduce the r-angle to about 5mm. When using this equipment, the r-angle of the optical glass was reduced to 3.5mm.
[0043] In some embodiments, see Figure 4 , Figure 5The support mechanism also includes a second support plate 502 and a spring 507. The first support plate 501 has a movable groove 506 inside. The second support plate 502 is slidably connected inside the movable groove 506. The spring 507 is fixedly installed between the movable groove 506 and the bottom of the second support plate 502. A support pad 508 is fixedly installed on the inner wall of the first support plate 501. The second support plate 502 is located between the first support plate 501 and the support pad 508. By setting the second support plate 502 and the spring 507, the second support plate 502 can slide inside the first support plate 501. The cooperation of the first support plate 501 and the second support plate 502 can support the optical glass inside the base 1, preventing the optical glass from tilting during the pressing process and affecting the pressing effect. The support pad 508 can prevent the second support plate 502 from tilting when moving in the movable groove 506. Since the second support plate 502 slides in the movable groove 506, the second support plate 502 will not affect the deformation of the optical glass during the pressing deformation process.
[0044] In some embodiments, see Figure 2 , Figure 3 The adjusting mechanism includes a protrusion 3, a threaded rod 301, and a first slider 303. Two protrusions 3 are provided, each fixedly mounted on one side of the base 1. The threaded rod 301 is rotatably connected inside the protrusion 3. Several first sliders 303 are provided, each fixedly mounted on the side wall of one of the two cylinders 2. The first slider 303 has a thread inside that matches the threaded rod 301. The thread of the threaded rod 301 is opposite in direction around the middle. Two first sliders 303 are respectively mounted on the threaded rod 301 at one end of the corresponding thread. The two first sliders 303 move synchronously in opposite directions. An adjusting rod 304 is rotatably connected inside the base 1, with one end of the adjusting rod 304 fixedly mounted... A second transmission gear 306 is fixedly installed, and a first transmission gear 305 is fixedly installed on the side wall of the threaded rod 301. The first transmission gear 305 meshes with the second transmission gear 306. By setting the first transmission gear 305 and the second transmission gear 306, the adjusting rod 304 can be connected to the threaded rod 301. By rotating the adjusting rod 304, the rotation of the threaded rod 301 can be controlled, making it more convenient to control the rotation of the threaded rod 301. When the threaded rod 301 rotates, the first slider 303 moves on the side wall of the threaded rod 301. By moving the first slider 303, the distance between the two cylinders 2 can be adjusted, so as to adjust the size of the pressed r angle according to the size of the optical glass.
[0045] In some embodiments, see Figure 1 , Figure 3A second slider 3032 is fixedly installed on the side wall of cylinder 2. Several second sliders 3032 are provided. Both protrusions 3 have grooves inside. A guide rail 302 is fixedly installed inside one of the grooves. The second slider 3032 is slidably connected to the side wall of the guide rail 302. The threaded rod 301 is rotatably connected inside the other groove. By setting the guide rail 302 and the second slider 3032, cylinder 2 can be made more stable during adjustment and movement.
[0046] For further details, please refer to the following: Figure 1 The base 1 has a scale groove 401 on its side wall, and the indicator 4 matches the scale groove 401. By opening the scale groove 401 on the side wall of the base 1 to match the indicator 4, the distance between the two cylinders 2 can be adjusted more accurately.
[0047] The servo motor 31, electric telescopic rod 41, first motor 53, second motor 89 and control switch group 11 involved in this embodiment can be freely configured according to the actual application scenario. The control switch group 11 controls the servo motor 31, electric telescopic rod 41, first motor 53 and second motor 89 using methods commonly used in the prior art.
[0048] The working process and principle of this invention are as follows: When in use, the optical glass is formed in a mold and moved forward with the conveyor belt to the device. It is then manually placed between the two first support plates 501 inside the base 1. The cylinder 2 is then ventilated through the air inlet and outlet pipes 205 to start the device. The cylinder 2 drives the transmission rod 201 to move up and down at a certain speed. The transmission rod 201 drives the pressure block 204 to squeeze the glass surface, causing the optical glass to deform and move to both sides to fill the angular radius of the optical glass and reduce it, thereby ensuring that the angular radius of the optical glass can be reduced to the greatest extent.

These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
