Description

Technical Field

[0001] This utility model belongs to the field of optical glass cutting technology, and in particular relates to an optical glass cutting machine. Background Technology

[0002] Currently, optical glass cutting is generally done manually, relying mainly on skilled workers using carbide or diamond glass cutters to manually scratch the surface of the optical glass. Then, downward pressure and localized cooling are applied to cause the optical glass to break along the scratches. However, manual cutting has insufficient cutting power, low efficiency, poor cross-sectional quality, and poor operational safety. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides an optical glass cutting machine that can improve the quality of the cross-section after optical glass is cut.

[0004] The objective of this utility model is achieved through the following technical solution: An optical glass cutting machine includes a clamping mechanism for clamping and fixing optical glass and slidably disposed on the side of an optical glass conveyor, and a reset mechanism for resetting the clamping mechanism after sliding. The sliding direction of the clamping mechanism matches the conveying direction of the optical glass conveyor. The optical glass cutting machine includes a scratching mechanism for scratching optical glass, a cooling mechanism for cooling optical glass, and a pressure applying mechanism for applying downward pressure to the scratched and cooled optical glass. The scratching mechanism, cooling mechanism, and pressure applying mechanism are all fixedly connected to the clamping mechanism.

[0005] The beneficial effects of adopting the above technical solution are as follows: the clamping mechanism can clamp and fix the optical glass and move synchronously with the optical glass by means of the thrust of the optical glass conveyor. Correspondingly, the scratching mechanism, cooling mechanism and pressure application mechanism also move synchronously with the optical glass. The scratching mechanism scratches the optical glass, the cooling mechanism locally cools the optical glass to create controllable stress cracks, and the pressure application mechanism applies downward pressure to the optical glass to separate the optical glass along the scratch crack direction, thereby realizing the cutting of the optical glass. In this process, the scratching mechanism, cooling mechanism and pressure application mechanism move synchronously with the optical glass, which can avoid stress concentration, make the crack propagation direction more vertical and stable, and improve the quality of the cross-section after the optical glass is cut. In addition, this optical glass cutting machine uses mechanized equipment such as clamping mechanism, reset mechanism, scratching mechanism, cooling mechanism and pressure application mechanism to cut optical glass, which can effectively improve cutting ability, cutting efficiency and operation safety.

[0006] Furthermore, the optical glass cutting machine includes a frame disposed outside the optical glass conveyor, a clamping mechanism slidably connected to the frame, a fixed end of a reset mechanism fixedly connected to the frame, and a movable end of the reset mechanism connected to the clamping mechanism.

[0007] Furthermore, the clamping mechanism includes two clamping members for clamping the upper and lower ends of the optical glass, respectively, with the two clamping members located at the upper and lower ends of the frame.

[0008] The beneficial effects of adopting the above technical solution are: the two clamping members clamp the optical glass from the upper and lower ends respectively, so that the optical glass is clamped more firmly.

[0009] Furthermore, the clamping mechanism includes a mounting frame, the upper and lower ends of which are slidably connected to the upper and lower ends of the frame, respectively. Two clamping components are respectively disposed at the upper and lower ends of the mounting frame. The scratching mechanism, cooling mechanism, and pressure applying mechanism are all fixedly connected to the mounting frame.

[0010] The beneficial effects of adopting the above technical solution are: this configuration allows the scratching mechanism, cooling mechanism, and pressure application mechanism to operate synchronously with the clamping mechanism.

[0011] Furthermore, the reset mechanism includes two reset components, the fixed ends of which are fixedly connected to the upper and lower ends of the frame, respectively, and the movable ends of which are connected to the upper and lower ends of the clamping mechanism, respectively.

[0012] The beneficial effects of adopting the above technical solution are: the two reset components can act on the upper and lower ends of the frame respectively, so that the clamping mechanism can be reset more easily and more smoothly.

[0013] Furthermore, the optical glass cutting machine includes a controller, which is electrically connected to a clamping mechanism, a reset mechanism, a scratching mechanism, a cooling mechanism, and a pressure application mechanism.

[0014] The beneficial effect of adopting the above technical solution is that this setting helps to improve the automation level of the cutting machine.

[0015] Furthermore, the optical glass cutting machine includes a sensor for detecting the position of the optical glass, and the sensor is electrically connected to the controller.

[0016] The beneficial effects of adopting the above technical solution are: the sensor detects the position of the optical glass so that the clamping mechanism can be activated in time when the optical glass is transferred to a certain position, and it is convenient to perform scratching, cooling and applying downward pressure after clamping.

[0017] Furthermore, the cooling mechanism is a compressed cold air ejection device.

[0018] The beneficial effects of adopting the above technical solution are as follows: the compressed cold air ejection device can eject compressed cold air onto the optical glass to locally cool the optical glass, thereby creating controllable stress cracks.

[0019] Furthermore, the pressure-applying mechanism is a pneumatic rod controlled by a solenoid valve.

[0020] The beneficial effects of adopting the above technical solution are as follows: the pneumatic rod can extend downward to apply downward pressure to the optical glass directly below it, thereby separating the optical glass along the direction of the scratch crack, thus realizing the cutting of the optical glass. Furthermore, the scratching mechanism and the cooling mechanism are integrated into the same machining head.

[0021] The beneficial effects of this utility model are as follows: The clamping mechanism can clamp and fix the optical glass and move synchronously with the optical glass by means of the thrust of the optical glass conveyor. Correspondingly, the scratching mechanism, cooling mechanism and pressure application mechanism also move synchronously with the optical glass. The scratching mechanism scratches the optical glass, the cooling mechanism locally cools the optical glass to create controllable stress cracks, and the pressure application mechanism applies downward pressure to the optical glass to separate the optical glass along the scratch crack direction, thereby realizing the cutting of the optical glass. In this process, the scratching mechanism, cooling mechanism and pressure application mechanism move synchronously with the optical glass, which can avoid stress concentration, make the crack propagation direction more perpendicular and stable, and improve the quality of the cross-section after the optical glass is cut. In addition, this optical glass cutting machine uses mechanized equipment such as clamping mechanism, reset mechanism, scratching mechanism, cooling mechanism and pressure application mechanism to cut optical glass, which can effectively improve cutting ability, cutting efficiency and operation safety.

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] This utility model provides an optical glass cutting machine, such as Figure 1 and Figure 2 As shown, it includes a clamping mechanism 3 for clamping and fixing optical glass and slidingly disposed around the optical glass conveyor 2, and a reset mechanism for resetting the clamping mechanism 3 after sliding. The sliding direction of the clamping mechanism 3 matches the conveying direction of the optical glass conveyor 2. The optical glass cutting machine includes a scratching mechanism 4 for scratching optical glass, a cooling mechanism 5 for cooling optical glass, and a pressure applying mechanism for applying downward pressure to the scratched and cooled optical glass. The scratching mechanism 4, the cooling mechanism 5, and the pressure applying mechanism are all fixedly connected to the clamping mechanism 3. The scratching mechanism 4 applies a constant force to scratch the optical glass.

[0026] Understandably, the clamping mechanism 3 can clamp and fix the optical glass and move synchronously with the optical glass by means of the thrust of the optical glass conveyor 2. Correspondingly, the scratching mechanism 4, the cooling mechanism 5, and the pressure applying mechanism also move synchronously with the optical glass. The scratching mechanism 4 scratches the optical glass, the cooling mechanism 5 locally cools the optical glass to create controllable stress cracks, and the pressure applying mechanism applies downward pressure to the optical glass to separate the optical glass along the scratch crack direction, thereby realizing the cutting of the optical glass. In this process, the scratching mechanism 4, the cooling mechanism 5, and the pressure applying mechanism move synchronously with the optical glass, which can avoid stress concentration, make the crack propagation direction more vertical and stable, and improve the quality of the cross-section after the optical glass is cut. In addition, the optical glass cutting machine uses mechanized equipment such as clamping mechanism 3, reset mechanism, scratching mechanism 4, cooling mechanism 5 and pressure application mechanism to cut optical glass, which can effectively improve cutting ability, cutting efficiency and operation safety.

[0027] In one embodiment, the optical glass cutting machine includes a frame 6 disposed outside the optical glass conveyor 2, a clamping mechanism 3 slidably connected to the frame 6, a fixed end of a reset mechanism fixedly connected to the frame 6, and a movable end of the reset mechanism connected to the clamping mechanism 3.

[0028] In one embodiment, the clamping mechanism 3 includes two clamping members 301 for clamping the upper and lower ends of the optical glass, respectively, with the two clamping members 301 located at the upper and lower ends of the frame 6.

[0029] Understandably, the two clamping members 301 clamp the optical glass from the top and bottom of the optical glass respectively, so that the optical glass is clamped more securely.

[0030] In one embodiment, the clamping mechanism 3 includes a mounting frame 302, the upper and lower ends of which are slidably connected to the upper and lower ends of the frame 6, respectively. Two clamping members 301 are respectively disposed at the upper and lower ends of the mounting frame 302. The scratching mechanism 4, the cooling mechanism 5, and the pressure applying mechanism are all fixedly connected to the mounting frame 302. The clamping member 301 may be an electric push rod driven by a servo, and a rubber clamp is fixed to one end of the electric push rod. The scratching mechanism 4 and the cooling mechanism 5 are integrated into the same processing head, which is mounted on the mounting frame 302. In addition, the pressure applying mechanism may be located directly above the optical glass conveyor 2 and applies downward pressure.

[0031] Understandably, this arrangement is intended to allow the scratching mechanism 4, cooling mechanism 5, and pressure application mechanism to operate synchronously with the clamping mechanism 3.

[0032] It should be noted that, as Figure 1 and Figure 2 As shown, the optical glass conveyor 2 can be a mesh belt conveyor. The middle part of the mesh belt conveyor may not be laid with a mesh belt in the length direction, so that the clamping end of the lower clamping member 301 can pass through this space without a mesh belt to act on the optical glass. The optical glass conveyor 2 can be divided into two sections with a certain height difference between them, so that after the pressure is applied by the pressure mechanism, the cut optical glass is pressed to the rear section of the optical glass conveyor 2. Correspondingly, the side of the mesh belt that is used to contact the optical glass can be covered with a material layer with a large coefficient of friction so that the mesh belt can stably transport the optical glass.

[0033] It should be noted that the processing head is a mechanism that can move along the width and height of the optical glass. It can perform operations on the same cutting line of the two glass plates on the optical glass conveyor 2 through the scratching mechanism 4 and the cooling mechanism 5, and can be configured to adapt to different sizes of glass. The processing head is also a common structure on the market, and its specific structure will not be described in detail here.

[0034] It should be noted that the clamping mechanism 3 uses two clamping parts 301 to clamp and fix the upper and lower ends of the optical glass. It is a high-rigidity clamping structure to provide a stable foundation for accurately applying scratches and stress. At the same time, the servo drive ensures the positioning accuracy and the programmability of the movement path.

[0035] In one embodiment, the reset mechanism includes two reset members. The fixed ends of the two reset members are fixedly connected to the upper and lower ends of the frame 6, respectively, and the movable ends of the two reset members are connected to the upper and lower ends of the clamping mechanism 3, respectively. The reset member can be an electric push rod. During the sliding process of the clamping mechanism 3, the rod of the electric push rod retracts as the clamping mechanism 3 slides. Subsequently, the electric push rod extends to reset the clamping mechanism 3.

[0036] Understandably, the two reset components can act on the upper and lower ends of the frame 6 respectively, so that the clamping mechanism 3 can be reset more easily and more smoothly.

[0037] In one embodiment, the optical glass cutting machine includes a controller, which is electrically connected to a clamping mechanism 3, a reset mechanism, a scratching mechanism 4, a cooling mechanism 5, and a pressure applying mechanism to improve the automation level of the cutting machine; wherein, the controller may be a PCB board equipped with a C51 microcontroller or a PLC integrated control system.

[0038] In one embodiment, the optical glass cutting machine includes a sensor for detecting the position of the optical glass, and the sensor is electrically connected to a controller; wherein the sensor may be a photoelectric sensor, which can be used to detect the position of the front end of the optical glass, that is, when the front end of the optical glass is conveyed onto the detection path of the sensor, the clamping mechanism 3 can be operated.

[0039] Understandably, the sensor detects the position of the optical glass so that the clamping mechanism 3 can be activated in time when the optical glass is transferred to a certain position, and facilitates scratching, cooling and application of downward pressure after clamping.

[0040] In one embodiment, the cooling mechanism 5 is a compressed cold air ejection device, and the scratching mechanism 4 can be a glass cutter head.

[0041] Understandably, compressed cold air ejection equipment can eject compressed cold air onto optical glass to locally cool the optical glass, thereby creating controllable stress cracks.

[0042] In one embodiment, the pressure-applying mechanism is a pneumatic rod controlled by a solenoid valve, which is electrically connected to the controller.

[0043] Understandably, the pneumatic rod can extend downwards to apply downward pressure to the optical glass directly below it, thereby separating the optical glass along the direction of the scratch crack, thus achieving optical glass cutting.

[0044] The working process of this utility model is as follows: Optical glass sheets are fed into optical glass conveyor 2 from rough annealing furnace 1; When the sensor detects the front end of the optical glass, the clamping mechanism 3 clamps and fixes the optical glass and moves synchronously with the optical glass by means of the pushing force of the optical glass. The telescopic end of the reset mechanism retracts with the clamping mechanism 3. The scratching mechanism 4 scratches the optical glass, and the cooling mechanism 5 sprays compressed cold air onto the optical glass to create controllable stress cracks. The pressure-applying mechanism applies downward pressure to the optical glass, causing the optical glass to separate along the direction of the scratch crack, thereby achieving optical glass cutting; The reset mechanism extends to reset the clamping mechanism 3.

[0045] It is understandable that by repeating the above work process, an uninterrupted production rhythm can be formed.

[0046] This utility model has the following significant advantages: This invention improves the cutting perfection by effectively solving the problems of stress transmission and crack propagation control in optical glass through the core design of constant force scratching and synchronous operation, thus achieving a stable and perfect cutting of optical glass. This invention significantly improves the cross-sectional quality. Specifically, it avoids stress concentration by operating in a uniform and synchronous manner, making the crack propagation direction more vertical and stable. It can control the chipping size to below 0.1mm, greatly reducing the workload and material consumption of subsequent edge grinding. This utility model has a high degree of automation and efficiency. Specifically, it integrates positioning, automatic scratching, cooling and stress application into one unit, realizing automated operation of the process. Compared with manual methods, it has higher precision and better consistency. This invention is safe and reliable, specifically avoiding direct contact between people and optical glass fragments and low-temperature media, thus improving safety.
