Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass polishing technology, and in particular to a glass flat grinding and polishing machine. Background Technology
[0002] In glass processing, glass sheets require surface grinding and polishing, which involves using the abrasive action of polishing powder and the hydration of the glass surface with water to perform surface treatment. Generally, surface grinding and polishing of glass sheets is carried out using a surface grinder.
[0003] The brush head's movement trajectory, pressure, and speed are key factors determining the polishing effect. However, in traditional polishing machines, the brush head and glass cover plate rotate in a planetary gear pattern, making it difficult to maintain a stable contact state between the brush head and the glass cover plate surface. Especially at the edges and center of the glass cover plate, the centrifugal force generated by rotation differs, causing variations in the contact pressure and area between the brush head and the glass surface. This variation directly results in a more irregular and unsightly polishing texture, hindering the improvement of surface quality consistency. Utility Model Content

The plane on which the glass cover plate is located is perpendicular to the top surface of the annular support, and the normal vector of the plane on which the glass cover plate is located is consistent with one of the radial directions of the annular support. By using the bristles to be set coaxially with the annular support, it can be ensured that the distance from the glass cover plate to the center of the bristles is always consistent, so that the glass cover plate always receives polishing from the same direction of the bristles, avoiding the appearance of messy polishing lines on the processed surface and effectively improving the consistency of surface quality.

[0028] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.
[0029] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.
[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0031] Please see Figures 1 to 8 The glass flat polishing machine according to one embodiment of the present invention includes a machine body 10, a clamping assembly 20 mounted on the machine body 10, and a polishing assembly 30 mounted above the clamping assembly 20.
[0032] The body 10 includes a base 11, a water-blocking plate 12 mounted on the top of the base 11, a power shaft 13 coaxially mounted in the middle of the water-blocking plate 12, and a motor (not shown) mounted inside the base 11; the motor is used to drive the power shaft 13 to rotate.
[0033] Specifically, the bottom end of the power shaft 13 passes through the base 11 and is connected to a motor to obtain a power source, while the top end of the power shaft 13 passes upward through the clamping assembly 20 and is connected to the sweeping assembly 30. In this embodiment, as... Figure 3 As shown, multiple slots 130 are evenly spaced on the outer peripheral surface of the top end of the power shaft 13. The slots 130 are used to match and connect the light-scanning assembly 30.
[0034] The clamping assembly 20 includes an annular support 21 and a plurality of fixtures 22 evenly spaced on the top of the annular support 21; the fixtures 22 are arranged radially outward along the radial direction of the annular support 21. A drive shaft 13 is coaxially mounted on the annular support 21, and the annular support 21 and the drive shaft 13 can rotate relative to each other. Understandably, the annular support 21 can be fixedly connected to the base 11, or it can be rotatably connected to the base 11, as long as a speed difference can be generated between the annular support 21 and the scanning assembly 30.
[0035] Please combine Figure 4 and Figure 5 To understand this, in actual use, the glass cover 23 is placed vertically inside the fixture 22, the plane of the glass cover 23 is perpendicular to the top surface of the annular support 21, and the normal vector of the plane of the glass cover 23 is consistent with one of the radial directions of the annular support 21.
[0036] The light-sweeping assembly 30 includes a gantry 31 connected to the base 11, a lifting cylinder 32 installed at the top center of the gantry 31, an upper turntable 33 rotatably connected to the end of the lifting cylinder 32, and bristles 34 installed on the bottom surface of the upper turntable 33; the upper turntable 33 is matched and connected downward to the power shaft 13 to obtain a power source.
[0037] In this embodiment, as Figure 8 As shown, multiple locking blocks 330 are evenly spaced along the inner circumference of the top surface of the upper turntable 33. The locking blocks 330 are used to match and embed into the locking slots 130 to achieve coaxial connection between the upper turntable 33 and the power shaft 13, so that the upper turntable 33 can rotate synchronously with the power shaft 13, thereby driving the brush bristles 34 to rotate and polish the processing surface of the glass cover plate 23.
[0038] In this embodiment, the bristles 34 are arranged in a ring shape and are coaxial with the ring-shaped support 21. The advantage of this design is that, assuming a trajectory circle is formed outward from the center of the top surface of the ring-shaped support 21 at the same distance D, multiple trajectory circles are formed as D gradually increases, namely the first trajectory circle, the second trajectory circle, and so on up to the Nth trajectory circle (N≥1), with all trajectory circles arranged concentrically. Similarly, the glass cover plates 23 are numbered from the inside out of the ring-shaped support 21, namely the first glass cover plate, the second glass cover plate, and so on up to the Nth glass cover plate (N≥1). Then, the plane containing the first glass cover plate is tangent to the first trajectory circle, the plane containing the second glass cover plate is tangent to the second trajectory circle, and so on. Since the bristles 34 and the annular support 21 are coaxially arranged, the distance from the glass cover plate 23 to the center of the bristles 34 can be kept consistent during the polishing process. This ensures that the glass cover plate 23 always receives polishing from the same direction of the bristles 34, avoiding the appearance of messy polishing patterns on the processed surface and effectively improving the consistency of surface quality.
[0039] like Figures 6 to 8 As shown, the lifting cylinder 32 is connected to the upper turntable 33 via a bearing 35; wherein, the inner ring of the bearing 35 is fixedly connected to the piston rod of the lifting cylinder 32, and the outer ring of the bearing 35 is fixedly connected to the upper rotating shaft 33.
[0040] The aforementioned glass flat polishing machine has a simple structure and is easy to use. The plane where the glass cover plate 23 is located is perpendicular to the top surface of the annular support 21. The normal vector of the plane where the glass cover plate 23 is located is consistent with one of the radial directions of the annular support 21. By using the bristles 34 and the annular support 21 to be set coaxially, it can be ensured that the distance from the glass cover plate 23 to the center of the bristles 34 is always consistent, so that the glass cover plate 23 always receives polishing from the same direction of the bristles 34, avoiding the appearance of messy polishing lines on the processed surface and effectively improving the consistency of surface quality.
[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
