Description

Technical Field

[0001] This utility model relates to the technical field of optical glass cutting device, and more particularly to an optical glass cutting device. Background Technology

[0002] Optical glass refers to glass that can change the direction of light propagation and alter 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-optical glass, and photochromic glass.

[0003] Chinese patent publication number CN219276256U discloses an optical glass cutting device, including a base. A support plate is mounted on the top of the base via a support member. A three-axis moving stage is mounted on the rear side of the support plate, and a motor is mounted on the three-axis moving stage. The output end of the motor is connected to a drilling bit. Several support arms are arranged at intervals along the left and right direction on the support plate. The top ends of the several support arms are hinged to a rotating plate. Mounting seats are fixed to both the left and right sides of the support plate. A first telescopic cylinder is horizontally fixed to the top of the mounting seat. Two first telescopic cylinders are arranged opposite each other. A clamping plate is fixed to the piston rod of the first telescopic cylinder. The rotating plate can abut against the bottom of the clamping plate. An adjustment mechanism for adjusting the tilt angle of the rotating plate is installed on the base. This utility model has an ingenious structure and can effectively improve processing efficiency.

[0004] Optical glass (such as K9 glass and quartz glass) typically exhibits low toughness and high brittleness. Existing optical glass cutting devices rely solely on clamps on both sides during cutting, which easily leads to indentations or micro-cracks at the edges. The central area of ​​the glass is also prone to minor warping or vibration, resulting in uneven stress on the optical glass and ultimately causing problems such as tilted cut surfaces and dimensional deviations. To overcome these disadvantages, this invention provides an optical glass cutting device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an optical glass cutting device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an optical glass cutting device, comprising a cutting table, the cutting table having a hollow internal structure, a first cutting groove being formed at the center of the top of the cutting table, a plurality of first rubber strips being uniformly fixed to both sides of the top of the cutting table at the first cutting groove, a pressure plate being provided above the cutting table, a first lifting assembly for driving the pressure plate to rise and fall being provided on the cutting table, a second cutting groove being formed on the pressure plate at a position corresponding to the first cutting groove, second rubber strips being fixed to the bottom side of the pressure plate at positions corresponding to the first rubber strips, a movable plate being provided inside the cutting table, fixed plates being symmetrically fixed to the movable plate at positions corresponding to the first cutting groove, a plurality of rotating shafts being rotatably connected between the fixed plates on both sides, cutting blades being fixed to the rotating shafts, a first driving assembly for driving the rotating shafts to rotate being provided on one side of the fixed plate, and a second lifting assembly for driving the movable plate to rise and fall being provided on the cutting table.

[0007] Furthermore, ear plates are symmetrically fixed to both sides of the pressure plate. The first lifting assembly includes support plates symmetrically fixed to both sides of the cutting table. An electric telescopic rod is fixed to one side of the support plate, and the output end of the electric telescopic rod is fixedly connected to the corresponding ear plate. A telescopic rod is fixed to the other side of the support plate, and the end of the telescopic rod is fixedly connected to the corresponding ear plate.

[0008] Furthermore, the first drive assembly includes a fixed box fixed to a fixed plate on one side, one end of the rotating shaft extends into the fixed box and is fixedly connected to a driven bevel gear, a connecting shaft is rotatably connected inside the fixed box, a driving bevel gear is fixedly connected to the connecting shaft at a position corresponding to the driven bevel gear, the driving bevel gear meshes with the corresponding driven bevel gear, a first motor is fixedly connected to the fixed box, and the output end of the first motor is fixedly connected to the connecting shaft.

[0009] Furthermore, the second lifting assembly includes a sliding groove formed on the bottom side inside the cutting table, with slide blocks symmetrically slidably connected in the sliding groove, and fixed seats symmetrically fixed to both sides of the moving plate, with connecting rods hinged in the fixed seats, the ends of the connecting rods being hinged to the corresponding slide blocks, and a second driving assembly for driving the slide blocks on both sides to move is provided on the cutting table.

[0012] The beneficial effects of this utility model are:

[0013] When in use, this optical glass cutting device has the following advantages:

[0014] 1. In this solution, the upper and lower clamping uses uniform surface contact pressure, combined with the first rubber strip on the top of the cutting table and the second rubber strip on the bottom of the pressure plate to form a corresponding structure, fixing the glass on a flat reference surface, completely restricting its vertical displacement and warping, and avoiding indentations or micro-cracks at the edges. When clamping optical glass, the friction of the rubber can achieve reliable anti-slip, avoiding the skewed cut caused by glass displacement during the cutting process, and the elasticity of the rubber can also play a buffering role, reducing the squeezing damage of the hard pressure plate to the surface of the optical glass. It is especially suitable for workpieces such as optical glass with high surface precision requirements and brittle materials.

[0015] 2. In this solution, the cutting blade is mounted on the fixed plate of the moving plate via a rotating shaft, and only passes through the first cutting groove of the cutting table to cut when it is raised. When not in operation, it can be lowered with the moving plate, reducing the safety hazards caused by the exposed blade.

[0016] 3. In this solution, by setting multiple sets of rotating shafts and cutting blades, multiple optical glasses held together can be cut simultaneously, thereby improving cutting efficiency. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-4 As shown, the present invention has the following specific embodiments.

[0026] Example 1

[0027] An optical glass cutting device includes a cutting table 1, which has a hollow interior. A first cutting groove 2 is formed at the center of the top of the cutting table 1. Several first rubber strips 3 are uniformly fixed to both sides of the top of the cutting table 1 at the first cutting groove 2. A pressure plate 5 is provided above the cutting table 1. A first lifting assembly for driving the pressure plate 5 to rise and fall is provided on the cutting table 1. A second cutting groove 6 is formed on the pressure plate 5 at the position corresponding to the first cutting groove 2. Second rubber strips 10 are fixed to the bottom side of the pressure plate 5 at the positions corresponding to the first rubber strips 3. A movable plate 11 is provided inside the cutting table 1. Fixed plates 12 are symmetrically fixed to the movable plate 11 at the position corresponding to the first cutting groove 2. Several rotating shafts 13 are rotatably connected between the two fixed plates 12. Cutting blades 14 are fixed to the rotating shafts 13. A first driving assembly for driving the rotating shaft 13 to rotate is provided on one side of the fixed plate 12. A second lifting assembly for driving the movable plate 11 to rise and fall is provided on the cutting table 1.

[0028] In this embodiment, as Figure 1-4As shown, the optical glass to be cut is placed on the cutting table 1. The first lifting component drives the pressure plate to press down on the optical glass. With the first rubber strip 3 of the cutting table 1 and the second rubber strip 10 on the bottom side of the pressure plate 5, the glass can be firmly fixed. The anti-slip properties of the rubber can also prevent the glass from shifting or shaking during the cutting process. At the same time, the buffering effect of the rubber strip effectively avoids the rigid pressing causing indentations or breakage of the optical glass (which is brittle and easily damaged), reducing material loss during processing. The first driving component drives the rotating shaft 13 and the cutting blade 14 to rotate. The second lifting component drives the rotating cutting blade 14 to rise and pass through the first cutting groove 2 to cut the pressed optical glass.

[0029] Example 2

[0030] The pressure plate 5 is symmetrically fixed with ear plates 7 on both sides. The first lifting assembly includes support plates 4 symmetrically fixed to both sides of the cutting table 1. An electric telescopic rod 8 is fixedly fixed on one side of the support plate 4. The output end of the electric telescopic rod 8 is fixedly connected to the corresponding ear plate 7. A telescopic rod 9 is fixedly fixed on the other side of the support plate 4. The end of the telescopic rod 9 is fixedly connected to the corresponding ear plate 7.

[0031] In this embodiment, as Figure 1 As shown, starting the electric telescopic rod 8 causes the pressure plate 5 to move up and down, and the telescopic rod 9 extends and retracts accordingly, which facilitates the pressing of the optical glass and improves the stability during cutting.

[0032] Example 3

[0033] The first drive assembly includes a fixed box 15 fixed to a fixed plate 12 on one side. One end of a rotating shaft 13 extends into the fixed box 15 and is fixedly connected to a driven bevel gear 16. A connecting shaft 17 is rotatably connected inside the fixed box 15. A driving bevel gear 18 is fixedly connected to the connecting shaft 17 at a position corresponding to the driven bevel gear 16. The driving bevel gear 18 meshes with the corresponding driven bevel gear 16. A first motor 19 is fixedly connected to the fixed box 15. The output end of the first motor 19 is fixedly connected to the connecting shaft 17.

[0034] In this embodiment, as Figure 2 , 3 As shown in Figure 4, the first motor 19 is started, which drives the connecting shaft 17 and the driving bevel gear 18 to rotate, which in turn drives the driven bevel gear 16 to rotate. As a result, the rotating shaft 13 and the cutting blade 14 rotate synchronously, which facilitates the simultaneous cutting of multiple optical glasses held in pressure and improves the cutting efficiency.

[0035] Example 4

[0036] The second lifting assembly includes a slide groove 20 formed inside the bottom side of the cutting table 1. Slide seats 22 are symmetrically slidably connected in the slide groove 20. Fixed seats 23 are symmetrically fixed to both sides of the moving plate 11. Connecting rods 24 are hinged in the fixed seats 23. The ends of the connecting rods 24 are hinged to the corresponding slide seats 22. A second driving assembly for driving the slide seats 22 on both sides to move is provided on the cutting table 1. The second driving assembly includes a bidirectional screw 21 rotatably connected in the slide groove 20. The bidirectional screw 21 has symmetrically formed threaded grooves with opposite directions of rotation. The slide seats 22 are threadedly engaged with the corresponding threaded grooves on the bidirectional screw 21. A second motor 25 is fixedly connected to the cutting table 1. The output end of the second motor 25 is fixedly connected to the bidirectional screw 21.

[0037] In this embodiment, as Figure 2 , 3 As shown, the second motor 25 is started, which drives the bidirectional screw 21 to rotate, thereby driving the slides 22 on both sides to move towards each other. With the combined action of the fixed seat 23 and the connecting rod 24, the moving plate 11 is lifted, and the cutting blade 14 passes through the first cutting groove 2 to cut the optical glass being held. In the non-working state, it can be lowered with the moving plate 11, reducing the safety hazards caused by the exposed blade.

[0038] A control panel 26 is fixedly mounted on the cutting table 1. The power input terminal of the control panel 26 is electrically connected to an external power source, and the power output terminal of the control panel 26 is electrically connected to the electric telescopic rod 8, the first motor 19, and the second motor 25.

[0039] The working principle of this utility model is as follows: The optical glass to be cut is placed on the cutting table 1. The electric telescopic rod 8 is started, which drives the pressure plate 5 to move downward to press the optical glass. The telescopic rod 9 retracts accordingly. The first rubber strip 3 on the cutting table 1 and the second rubber strip 10 on the bottom side of the pressure plate 5 play a role in anti-slip buffering. The first motor 19 is started, which drives the connecting shaft 17 and the active bevel gear 18 to rotate, which in turn drives the driven bevel gear 16 to rotate. Thus, the rotating shaft 13 and the cutting blade 14 rotate synchronously. The second motor 25 is started, which drives the bidirectional screw 21 to rotate, which in turn drives the sliding seats 22 on both sides to move towards each other. With the linkage of the fixed seat 23 and the connecting rod 24, the moving plate 11 is lifted. The cutting blade 14 passes through the first cutting groove 2 to cut the pressed optical glass.
