Description

Technical Field

[0001] This application relates to the field of glass product processing technology, and in particular to glass disc polishing equipment. Background Technology

[0002] Glass disks, due to their excellent optical and mechanical properties, are widely used in high-precision products such as optical lenses, semiconductor wafer carriers, and display substrates. These products have extremely high requirements for the surface flatness and smoothness of the glass disks, and the polishing process is a core factor determining the quality of the products.

[0003] Current glass disc polishing equipment generally uses a frame as the basic support framework. The frame is equipped with a rotating bearing component for placing the glass disc. This component is driven by a drive device to rotate, providing the basic motion for polishing. At the same time, a polishing execution component is set above the rotating bearing component on the frame to apply pressure to the surface of the glass disc and complete the polishing action.

[0004] Regarding the aforementioned technologies, the inventors believe that insufficient stability in the cooperation between the rotating bearing component and the driving device can easily lead to fluctuations in the rotation speed of the glass disc during rotation, resulting in uneven polishing pressure and polishing trajectory, and affecting the uniformity of the glass disc surface thickness and flatness. Utility Model Content

[0005] The purpose of this application is to provide a glass disc polishing device to improve the problem that the lack of stability in the cooperation between the rotating bearing component and the drive device can easily lead to fluctuations in the rotation speed of the glass disc during rotation, resulting in uneven polishing pressure and polishing trajectory, and affecting the uniformity of the thickness and flatness of the glass disc surface.

[0006] The glass disc polishing equipment provided in this application adopts the following technical solution: A glass disc polishing device includes a frame, on which a polishing disc body for placing a glass disc is rotatably mounted, and a drive unit for driving the polishing disc body to rotate. A polishing head unit is mounted on the frame above the glass disc on the polishing disc body. Several limiting guide wheels are mounted around the frame around the polishing disc body, contacting the edge of the glass disc. A second limiting guide wheel corresponding to the edge of the glass disc is mounted at the center of the frame around the polishing disc body. A robotic arm unit for picking up and placing the glass disc is mounted on the side wall of the frame.

[0007] By adopting the above technical solution, the polishing disc body, in conjunction with the polishing head unit located directly above the glass disc, presses the glass disc onto the polishing disc body. The polishing disc body rotates to continue polishing the glass product beneath the ceramic sheet on the glass disc. The polishing head unit also drives the glass disc to rotate, stabilizing the polishing trajectory and ensuring the consistency of the polished surface thickness and flatness, thus guaranteeing the continuity and efficiency of the polishing process. Simultaneously, limiting guide wheels are installed around the polishing disc body, contacting the edge of the glass disc, and a second limiting guide wheel is installed in the center, corresponding to the edge of the glass disc. This effectively constrains the radial displacement of the glass disc during rotation, preventing surface scratches or localized over-polishing. The robotic arm unit on the side wall of the frame replaces manual labor in picking up and placing the glass disc, precisely controlling the placement position, shortening process intervals, and significantly improving the automation level and overall production efficiency of the equipment.

[0008] Optionally, the robotic arm unit includes a vacuum suction cup for adsorbing the glass disc and a mounting base connected to the vacuum suction cup. A drive cylinder is provided at the end of the mounting base away from the vacuum suction cup, and a drive component is provided on the side wall of the frame to drive the vacuum suction cup to rotate upwards towards the main body of the throwing disc.

[0009] By adopting the above technical solution, the drive component 2 on the side wall of the frame drives the drive cylinder 1 and the vacuum suction cup to rotate as a whole, which can realize the arc-shaped transfer path of the glass disc between the storage area and the main body of the polishing plate. Through precise rotation angle control, the glass disc is accurately placed in the preset position of the main body of the polishing plate. The cooperation between the mounting base and the drive cylinder 1 can flexibly adjust the distance between the vacuum suction cup and the glass disc by extending and retracting the cylinder. After the vacuum suction cup is attached to the surface of the glass disc, the air pump is used to draw air so that the vacuum suction cup can adsorb the glass disc, preventing the glass from falling off during the transfer process.

[0010] Optionally, the frame is provided with a fixed frame at the edge of the throwing disc body, and the fixed frame is rotatably provided with a connecting frame, the end of the connecting frame being rotatably connected to a limiting guide wheel.

[0011] By adopting the above technical solution, the connecting frame can drive the limiting guide wheel to rotate away from the main body of the throwing plate. When needed, the limiting guide wheel can be turned back to the main body of the throwing plate. At the same time, the connecting frame can be finely adjusted after the glass disc is placed to ensure that the limiting guide wheel is in close contact with the edge of the glass disc without excessive compression. While ensuring the limiting effect, it avoids damage to the edge of the glass disc due to excessive compressive stress.

[0012] Optionally, the blasting head unit includes a pressure plate and a driving component three for driving the pressure plate to rotate, and the frame is provided with a driving cylinder two for driving the pressure plate to move down and press the glass disc towards the blasting disc body.

[0013] By adopting the above technical solution, the driving component three can drive the pressure plate to rotate, so that the pressure plate rotates while applying polishing pressure to the glass disc. Compared with the traditional fixed polishing head that relies solely on the rotation of the glass disc to achieve polishing, the active rotation of the pressure plate can increase the relative motion trajectory with the surface of the glass disc, making the polishing abrasive of the polishing disc body act more evenly on the surface of the glass disc, reducing polishing marks or local insufficient polishing, and significantly improving the surface smoothness of the glass disc. The driving cylinder two, which is set on the frame facing the polishing disc body, can drive the pressure plate to move downward in the vertical direction. The pressure output by the driving cylinder two can accurately control the polishing pressure of the pressure plate on the glass disc.

[0014] Optionally, there is a gap between the first limiting guide wheel, the second limiting guide wheel and the main body of the throwing plate. After the pressure plate presses down on the glass disc, the first limiting guide wheel and the second limiting guide wheel together limit the glass disc. The first limiting guide wheel and the second limiting guide wheel rotate together with the glass disc.

[0015] By adopting the above technical solution, a gap is reserved between the first and second limiting guide wheels and the polishing disc body to prevent direct contact between the guide wheels and the polishing disc body, thus preventing friction and wear and extending the service life of the components. At the same time, it prevents metal debris or impurities generated by friction from contaminating the surface of the glass disc, ensuring a clean polishing environment. When the pressure plate presses down and presses the glass disc tightly onto the polishing disc body, the first and second limiting guide wheels together form a radial constraint. When the glass disc rotates, the friction force will drive the guide wheels to move synchronously, preventing sliding friction between the guide wheels and the glass disc and preventing wear or scratches on the edge of the glass disc. During the following process, the guide wheels continuously limit the glass disc, ensuring that the glass disc always rotates along the preset trajectory, further improving the polishing accuracy and surface consistency.

[0016] Optionally, the thickness of the first limiting guide wheel and the second limiting guide wheel is greater than the thickness of the glass disk.

[0017] By adopting the above technical solution, the thickness of the first and second limiting guide wheels is set to be greater than the thickness of the glass disk. When the guide wheels contact the edge of the glass disk, their vertical coverage can completely cover the thickness range of the glass disk, forming a limiting constraint on the vertical direction of the glass disk. This design can effectively resist the vertical warping or displacement of the glass disk caused by factors such as the pressure of the polishing head unit and the rotational inertia of the polishing disk body during the polishing process.

[0018] Optionally, the drive unit has a detection module for detecting glass discs on three side walls facing the main body of the polishing disc, and the frame is provided with a mounting bracket connected to the detection module.

[0019] By adopting the above technical solution, the detection end of the detection module can be accurately aligned with the glass disc on the polishing plate body to achieve real-time monitoring during the polishing process. The detection data can be fed back to the control system in real time. When the detected parameters deviate from the preset standard, the control system can immediately adjust the polishing pressure of the polishing head unit, the rotation speed of the polishing plate body or the pressure plate, and other working parameters.

[0020] Optionally, the frame is provided with a high-pressure cleaning unit facing the glass disc, and a drainage gap is left between the main body of the polishing disc and the frame.

[0021] By adopting the above technical solution, a high-pressure cleaning unit is installed on the frame facing the glass disc. After polishing, the high-pressure cleaning unit can spray high-pressure water onto the surface of the glass disc through the spray end to quickly clean the surface of residual polishing liquid, abrasive debris and other impurities. A drainage gap is reserved between the polishing disc body and the frame. The waste liquid generated during cleaning can flow naturally through this gap to the drainage or recycling device below the equipment to prevent the waste liquid from flowing back to the surface of the glass disc and causing secondary pollution.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The polishing head unit presses the glass disc onto the polishing disc body. The glass product under the ceramic sheet of the glass disc is further polished by the rotation of the polishing disc body. The polishing head unit also drives the glass disc to rotate, so as to stabilize the polishing trajectory of the glass disc, ensure the thickness consistency and flatness of the polished surface of the glass disc, and ensure the continuity and efficiency of the polishing action. 2. The driving component can drive the pressure plate to rotate, so that the pressure plate rotates while applying polishing pressure to the glass disc. Compared with the traditional fixed polishing head that relies solely on the rotation of the glass disc to achieve polishing, the active rotation of the pressure plate can increase the relative motion trajectory with the surface of the glass disc, making the polishing abrasive of the main body of the polishing plate act more evenly on the surface of the glass disc, reducing polishing marks or local insufficient polishing, and significantly improving the surface smoothness of the glass disc. 3. A gap is reserved between the first and second limiting guide wheels and the main body of the polishing disc to prevent the guide wheels from directly contacting the main body of the polishing disc and causing friction and wear, thereby extending the service life of the components. At the same time, it prevents metal shavings or impurities generated by friction from contaminating the surface of the glass disc and ensures a clean polishing environment.

The upper surface of the polishing disc body 2 is covered with polishing abrasive. The polishing disc body 2 is used to support the glass disc 3 to be polished. A drive component 21 is mounted below or on the side of the polishing disc body 2. The drive component 21 is a drive motor electrically connected to a power source. The output end of the drive component 21 is connected to the rotating shaft of the polishing disc body 2 through a coupling or transmission belt, which can drive the polishing disc body 2 to rotate smoothly around its own axis. A polishing head unit 4 is mounted on the frame 1 directly above the polishing disc body 2 via a crossbeam or bracket. The polishing head unit 4 includes a pressure plate 4. 1. A drive component 3 42 is connected above the pressure plate 41. The drive component 3 42 is also a drive motor that is electrically connected to the power supply. The output shaft of the drive component 3 42 is fixed coaxially with the pressure plate 41 and can drive the pressure plate 41 to rotate around its own axis. A drive cylinder 2 43 is also installed on the frame 1 at the position corresponding to the throwing head unit 4. The piston rod of the drive cylinder 2 43 is vertically downward and its end is fixedly connected to the mounting plate (not shown in the figure) on the outside of the drive component 3 42. It can drive the pressure plate 41 to move up and down in the vertical direction to adjust the distance between the pressure plate 41 and the glass disc 3 on the throwing plate body 2.

[0027] Reference Figure 1 and Figure 2 Several limiting guide wheels 5 are evenly distributed along the circumference on the frame 1 around the main body 2 of the polishing disc. A fixing frame 11 is installed on the frame 1 at the edge of the main body 2 of the polishing disc by bolts. The fixing frame 11 is rotatably connected to the connecting frame 12 by a rotating shaft. The end of the connecting frame 12 is rotatably engaged with the limiting guide wheel 5 by a bearing. At the center of the main body 2 of the polishing disc, a limiting guide wheel 6 is installed on the frame 1 by a support rod. The installation height of the limiting guide wheel 6 is consistent with that of the limiting guide wheel 5, and the thickness of both is greater than that of the common glass disc 3 to be polished, so as to ensure that the edge of the glass disc 3 can be covered from the top and bottom.

[0028] Reference Figure 1 and Figure 2A robotic arm unit 7 is mounted on one side wall of the frame 1. The robotic arm unit 7 includes a vacuum suction cup 71 with its suction surface facing downwards. The vacuum suction cup 71 is fixedly connected to the mounting base 72 by bolts. The vacuum suction cup 71 is connected to an air pump (not shown in the figure) through a connecting pipe. The air pump draws air to create a negative pressure to adsorb the glass disc 3. The end of the mounting base 72 away from the vacuum suction cup 71 is connected to the piston rod end of the drive cylinder 73. The drive component 74 is fixed to the side wall of the frame 1 by a flange. The drive component 74 is a telescopic rotary motor that is electrically connected to a power source. Its output end is fixedly connected to the cylinder body of the drive cylinder 73. It can drive the drive cylinder 73, the mounting base 72 and the vacuum suction cup 71 to rotate together around the axis of the drive component 74, so as to realize the transfer of the glass disc 3 between the storage area and the throwing plate body 2.

[0029] Reference Figure 1 and Figure 2 A detection module 13 is installed on the side wall of the drive component 3 42 facing the polishing disc body 2. The detection module 13 is connected to the frame 1 through the mounting bracket 14. The detection module 13 is electrically connected to the control system in the frame 1 to detect the polishing process of the glass disc 3. The frame 1 is also equipped with a high-pressure cleaning unit 8. The spray pipe of the high-pressure cleaning unit 8 (not shown in the figure) surrounds the top or side of the polishing disc body 2. The nozzle of the spray pipe faces the surface of the glass disc 3. A drainage gap 15 is reserved between the polishing disc body 2 and the frame 1. A waste liquid collection or treatment device can be connected below the gap.

[0030] The implementation principle of this application embodiment is as follows: Limiting guide wheel 5 and limiting guide wheel 6 contact the edge of the glass disk 3 from the periphery and center respectively, forming a double radial limit. Drive component 21 is activated, driving the throwing disc body 2 and the glass disk 3 above it to rotate together around the axis of the throwing disc body 2 via the transmission structure. Simultaneously, the piston rod of drive cylinder 43 extends, driving the throwing head unit 4 and pressure plate 41 to move downwards, so that the pressure plate 41 fits against the upper surface of the glass disk 3. Drive component 42 is activated, driving the pressure plate 41 to rotate around its own axis. The rotation of the pressure plate 41 and the rotation of the glass disk 3 form a... The composite motion trajectory ensures that the polishing surface of the polishing disc uniformly polishes the glass product beneath the ceramic sheet of the glass disc 3. Once the glass disc 3 is polished, the main body 2 of the polishing disc stops rotating, and the piston rod of the second drive cylinder 43 retracts, causing the pressure plate 41 to move upwards and detach from the surface of the glass disc 3. The high-pressure cleaning unit 8 is activated, and the spray pipe sprays high-pressure water onto the surface of the glass disc 3, washing away any residual polishing liquid and abrasive debris. After cleaning, the robotic arm unit 7 transfers the cleaned glass disc 3 from the main body 2 to the unloading area. The polishing head unit 4 presses the glass disc 3 onto the main body 2, and the rotation of the main body 2 continues to polish the glass product beneath the ceramic sheet of the glass disc 3. The polishing head unit 4 also drives the glass disc 3 to rotate, stabilizing the polishing trajectory of the glass disc 3, ensuring the consistency of the polished surface thickness and flatness, and guaranteeing the continuity and efficiency of the polishing action.
