Description

Technical Field

[0001] This invention relates to the field of glass polishing machine technology, and in particular to a polishing machine with a detection function. Background Technology

[0002] A glass polishing machine is a precision industrial device used to improve the flatness and smoothness of glass surfaces. It typically uses a combination of mechanical friction and chemical action, employing a rotating grinding or polishing disc with abrasives or polishing fluids of different grit sizes to gradually remove scratches, bumps, and imperfections from the glass surface, ultimately achieving a transparent, smooth, and mirror-like visual effect. This equipment is widely used in the finishing processes of glass products such as building curtain walls, automotive glass, optical lenses, and displays.

[0003] In the polishing process of glass edges, due to the differences in the shape, size, and thickness of the glass to be processed, the general clamping method is often difficult to adapt to the specific requirements of different glass specifications. As a result, the polished glass is prone to deformation or damage. Specifically, for thicker glass, the edge area is easily subjected to downward pressure during the polishing process, causing the center of the glass to bulge upward. For thinner glass, the equipment vibration can easily cause resonance during polishing. This resonance can be transmitted to the glass body, potentially damaging its structural integrity. For example, Chinese patent application CN119748274A discloses a glass polishing machine that expands the area of ​​the upper plate for adsorbing glass by flipping the extension plate, making it suitable for polishing various types of glass and improving its applicability and convenience. However, this solution still mainly relies on a uniform adsorption clamping method and does not make targeted adjustments to the clamping force, support method, or damping buffer according to the differences in glass thickness. Therefore, when processing glass with large thickness differences, this method still cannot effectively avoid the problems of edge deformation of thick glass and resonance damage of thin glass, reflecting its limited adaptability.

[0004] Therefore, how to provide a polishing machine with detection function is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

For thick glass, the vacuum suction cup three is moved outward to strengthen edge support and prevent deformation. This design enables the device to adapt to glass of different specifications, improving process adaptability and operating efficiency. 2. This invention employs a buffer mechanism combining magnetorheological fluid and elastic pads. The state of the magnetorheological fluid can be controlled by an electromagnetic coil according to the glass thickness: when processing thick glass, it is solidified to provide rigid support and prevent the edges from bending downwards; when processing thin glass, the magnetorheological fluid is liquefied and the vibration energy is converted into liquid flow dissipation through a piston and damping orifice, effectively absorbing the vibration generated during polishing, avoiding glass breakage due to resonance, and improving the safety of the processing process and the yield of finished products. 3.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0018] Example 1: Reference Figure 1-9 This invention provides a technical solution: a polishing machine with a detection function, including a machine base 1 and a moving mechanism 2. The moving mechanism 2 is located on the top of the machine base 1. A lifting mechanism 3 is provided on the guide rail of the moving mechanism 2. The moving mechanism 2 is used to change the position of the lifting mechanism 3 when it moves. A polishing mechanism 4 is provided on the front of the lifting mechanism 3. When working, the polishing mechanism 4 can drive the polishing head to move up and down and contact the edge of the glass. Cooling mechanisms 5 are provided on the left and right sides of the polishing mechanism 4 on the front of the lifting mechanism 3. By providing cooling mechanisms 5, cooling can be carried out simultaneously when the polishing head polishes the edge of the glass, avoiding damage to the glass caused by thermal stress. An optical detection mechanism 6 is provided on the lower inner side of the moving mechanism 2. The optical detection mechanism 6 can acquire and detect images of the glass in real time during the processing. The machine also includes: Vacuum suction cup 701 is set on the top of the machine tool base 1 and is used to adsorb and support the center of the bottom of the glass to improve the support force of the center of the bottom of the glass. There are four vacuum suction cups 702, which are distributed circumferentially on the outside of vacuum suction cup 701. They are used to adsorb and support the four corners of the bottom of the glass, thereby improving the support of the four corners of the bottom of the glass. Vacuum suction cup 3 704, with a guide arm plate 703 on the outside of vacuum suction cup 1 701, is located inside the guide arm plate 703 and is driven to move inside the guide arm plate 703 by a driving device located on the lower side of the guide arm plate 703. This is used to change the adsorption and clamping position of vacuum suction cup 3 704. By changing the position of vacuum suction cup 3 704, the pressure can be more evenly distributed according to the different characteristics of thin / thick glass. The protective shell 803 is located on the side of the guide arm plate 703 away from the vacuum suction cup 701. An elastic pad 806 is provided on the top of the protective shell 803. The top of the elastic pad 806 contacts the bottom of the glass. The elastic pad 806 is used to support the bottom edge of the glass. The elastic pad 806 can switch functions synchronously with the change of the magnetorheological fluid state in the fixed cylinder 804. Vacuum suction cup 1 701, vacuum suction cup 2 702 and vacuum suction cup 3 704 are all connected to an external air pump to control the negative pressure when vacuum suction cup 1 701, vacuum suction cup 2 702 and vacuum suction cup 3 704 are adsorbing, so that vacuum suction cup 1 701, vacuum suction cup 2 702 and vacuum suction cup 3 704 have the function of adsorbing and clamping the bottom of the glass.

[0019] Working principle: The adsorption support method is pre-adjusted according to the thickness of the glass to be processed. When adsorbing and clamping thin glass, the electric telescopic rod 801 is controlled to move the vacuum suction cup 704 in the middle of the sliding seat 802 to the inside of the guide arm plate 703 near the vacuum suction cup 701. This provides multi-point adsorption for thin glass, making the pressure of the thin glass more evenly distributed. When adsorbing and clamping thick glass, the electric telescopic rod 801 is controlled to move the vacuum suction cup 704 away from the vacuum suction cup 701 inside the guide arm plate 703. This allows the vacuum suction cup 704 to move closer to the bottom edge of the thick glass, effectively supporting the bottom edge of the thick glass and preventing edge deformation during processing.

[0020] When processing thick glass, the magnetorheological fluid solidifies, providing a certain rigidity to the bottom of the thick glass with the elastic pad 806 for support. When processing thin glass, the magnetorheological fluid liquefies, and the vibrations generated during the thin glass processing are introduced to the piston plate 807 through the elastic pad 806 and the lifting linkage 805. Since the magnetorheological fluid is in a fluid state at this time, the magnetorheological fluid needs to pass through the pressure holes on the piston plate 807 when the piston plate 807 in the fixed cylinder 804 moves. This causes the piston plate 807 to generate resistance when moving in the fixed cylinder 804, which can absorb the energy of the vibrations generated during the thin glass processing and avoid resonance that could damage the glass.

[0021] Example 2: Reference Figure 1-7 Based on Embodiment 1, the present invention provides a technical solution: it further includes a directional adsorption clamping component 7, which is composed of a vacuum suction cup 1 701, a vacuum suction cup 2 702, a guide arm plate 703, a vacuum suction cup 3 704, a ventilation ring pipe 705, and an air pump connecting pipe 706. Vacuum chuck 1 701 and vacuum chuck 2 702 are both fixedly connected to the top of the machine tool base 1. Guide arm plate 703 is fixedly connected to the top outer side of vacuum chuck 1 701. Ventilation ring pipe 705 is fixedly connected to the top of the machine tool base 1 and is located outside of vacuum chuck 1 701. Vacuum chuck 3 704 is fixedly connected to the top of ventilation ring pipe 705. Air pump connecting pipe 706 is fixedly connected to the right side of ventilation ring pipe 705.

[0022] It also includes a switching assembly 8, which consists of an electric telescopic rod 801, a sliding seat 802, a protective shell 803, a fixed cylinder 804, a lifting connecting rod 805, an elastic pad 806, a piston plate 807, a spring 808, and an electromagnetic coil 809. The electric telescopic rod 801 is fixedly connected to the bottom of the guide arm plate 703 near the side of the vacuum suction cup 701. The electric telescopic rod 801 has a telescopic end. The sliding seat 802 is fixedly connected to the telescopic end of the electric telescopic rod 801. The protective shell 803 is fixedly connected to the front and back of the guide arm plate 703. The fixed cylinder 804 is fixedly connected to the middle of the inner part of the protective shell 803. The lifting link 805 is slidably connected to the middle of the top of the fixed cylinder 804. The elastic pad 806 is fixedly connected to the top of the lifting link 805. The piston plate 807 is fixedly connected to the bottom of the lifting link 805. The spring 808 is fixedly connected to the bottom of the piston plate 807. The electromagnetic coil 809 is disposed between the outer wall of the fixed cylinder 804 and the inner wall of the protective shell 803.

[0023] A sliding groove is provided on the side of the guide arm plate 703 away from the vacuum suction cup 701. The sliding seat 802 is located in the sliding groove and is slidably connected to the sliding groove.

[0024] A slot is provided in the middle of the sliding seat 802. The vacuum suction cup 704 is set in the slot and fixedly connected to the sliding seat 802. A telescopic tube is provided at the bottom of the vacuum suction cup 704. The vacuum suction cup 704 is fixedly connected to the top of the ventilation ring pipe 705 through the telescopic tube. The vacuum suction cup 704 is connected to the inside of the ventilation ring pipe 705 through the telescopic tube. The end of the air pump connecting pipe 706 away from the ventilation ring pipe 705 is connected to an external air pump.

[0025] The fixed cylinder 804 is filled with magnetorheological fluid, the bottom of the spring 808 is fixedly connected to the inner wall of the bottom of the fixed cylinder 804, and the piston plate 807 has pressure holes that communicate with each other at the top and bottom.

[0026] An insulating layer is provided on the inside of the protective shell 803, and the electromagnetic coil 809 is connected to an external power source.

[0027] Working principle: The support state of the elastic pad 806 is pre-adjusted according to the thickness of the glass to be processed. Current is input to the electromagnetic coil 809 via a power supply device. When the power supply device supplies power to the electromagnetic coil 809 (when processing thick glass), the magnetorheological fluid inside the fixed cylinder 804 solidifies. This solidified fluid fills the space between the piston plate 807 and the fixed cylinder 804, making it difficult to change the position of the piston plate 807. This allows the elastic pad 806 on the piston plate 807 to provide rigid support to the bottom of the thick glass, preventing edge compression due to poor edge support. The power supply device then controls the current input to the electromagnetic coil 809. 9. In the power-off state (when thin glass processing is required), the magnetorheological fluid in the fixed cylinder 804 is in a fluid state. The vibration generated by the thin glass during polishing is guided to the piston plate 807 through the elastic pad 806 and the lifting connecting rod 805, causing the spring 808 at the bottom of the piston plate 807 to undergo elastic deformation. At the same time, the piston plate 807 moves up and down in the magnetorheological fluid in the fixed cylinder 804, causing the magnetorheological fluid to flow in the pressure holes opened on the piston plate 807. This converts the vibration into pressure when the magnetorheological fluid flows in the pressure holes on the piston plate 807, thereby absorbing the energy of the vibration generated during operation. This ensures that the device remains targeted when adsorbing and clamping glass of different thicknesses.

[0028] Example 3: Reference Figure 8-9 Based on Embodiment 2, the present invention provides a technical solution that further includes an auxiliary component 9, which consists of a drive frame 901, a hinged connecting rod 902, a support point adjustment slide 903, a return spring 904, a displacement seat 905, a rotating support rod 906, and a support pad 907. The drive frame 901 is fixedly connected to the outside of the sliding seat 802. The hinged connecting rod 902 is hinged to the middle of the drive frame 901. The support point adjustment slide 903 is fixedly connected to the top of the machine tool base 1 and is located in the middle of two adjacent guide arm plates 703. The return spring 904 is fixedly connected to the inside of the support point adjustment slide 903 and is located on the side close to the vacuum chuck 701. The displacement seat 905 is fixedly connected to the other end of the return spring 904. The rotating support rod 906 is rotatably connected to the top of the displacement seat 905. The support pad 907 is fixedly connected to the top of the rotating support rod 906. The displacement seat 905 is slidably connected to the inside of the support point adjustment slide 903.

[0029] When polishing the top of thin glass, the polishing wheel divides the top of the thin glass into four quadrants with the center as the origin. The lack of effective support in each quadrant area makes it prone to resonance during polishing, potentially damaging the thin glass. To address this, the electric telescopic rod 801 is activated, positioning the sliding seat 802 within the guide arm plate 703 closer to the vacuum suction cup 701. This ensures the distance between the four sliding seats 802 remains constant. Simultaneously, the hinged connecting rod 902 is in its initial state, with no contact between it and the rotating support rod 906 and support pad 907. This allows the rotating support rod 906 and support pad 907 to be in their initial positions, forming a ring around the outside of the vacuum suction cup 701. The small spacing between the multiple rotating support rods 906 and support pads 907 creates a surface-contact support effect on the top of the thin glass, enhancing the support force on the underside of the thin glass and preventing damage during polishing. Vibration and resonance can cause damage. When polishing the top of thick glass, the lack of support below the four quadrants of the top of the thick glass can cause damage and breakage when the polishing wheel polishes this area. At this time, the electric telescopic rod 801 is controlled to move the sliding seat 802 within the guide arm plate 703 to the side away from the vacuum suction cup 701. While the vacuum suction cup 704 supports the bottom edge of the thick glass, the distance between the four adjacent sliding seats 802 increases, causing the hinge link 902 to rotate within the drive frame 901 and move away from the vacuum suction cup 701. During the movement of the hinge link 902, the hinge link 902 contacts the rotating support rod 906, which can push the rotating support rod 906 to move. At the same time, the return spring 904 is stretched, allowing the rotating support rod 906 and the support pad 907 to move to the designated position and provide fixed-point support for the bottom of the thick glass to avoid damage during polishing.

[0030] During polishing, the mode is switched based on the thickness of the glass. Then, the polishing mechanism 4 is controlled to make the polishing head contact the edge of the glass for polishing. The position of the polishing head can be adjusted by the moving mechanism 2. At the same time, during the polishing process, the cooling mechanism 5 is connected to external coolant to cool the polishing area in real time. During the polishing process, the optical detection mechanism 6 works to collect images during the polishing process and detect defects generated during polishing in real time.

[0031] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
