Description

Technical Field

[0001] The present invention relates to the technical field of glass processing equipment, and in particular to a polishing device for grinding the edges of glass. Background Art

[0002] The grinding process of a glass substrate is a process in which the glass substrate rubs against a high-speed rotating grinding wheel, so that the edge size of the glass substrate meets certain quality requirements. In the deep processing of glass, in order to obtain a higher smoothness of the glass edge, the grinding process of peripheral grinding or double-sided grinding equipment is often relied on to meet its quality requirements. However, in the grinding process, usually only one side of the glass is ground and polished. After the grinding and polishing of this side are completed, then the next side is ground; in addition, since there are upper and lower edge parts on one side of the glass, it is currently difficult to grind the upper and lower edge parts simultaneously, which greatly reduces the grinding and polishing efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a polishing device for grinding the edges of glass, which solves the technical problem of how to greatly increase the grinding and polishing efficiency of the edges of a glass plate. It can simultaneously perform the grinding and polishing processes on the four sides and the upper and lower edge parts of the glass plate, greatly improving the production efficiency without affecting the quality of the glass plate.

[0020] The beneficial effects of the present invention are as follows:

[0021] (1) The up-and-down polishing structure provided in this solution can achieve the following technical effects:

[0022] First, the upper and lower edges of the side of the glass plate are respectively in contact with the outer sides of the polishing column one and the polishing column two. The polishing column one and the polishing column two respectively rotate by a certain angle and are in a V shape with the opening facing the glass plate, realizing the simultaneous grinding and polishing of the upper and lower edges of the glass plate;

[0023] Second, four up-and-down polishing structures are provided in this solution and are distributed on the four sides of the glass plate, and the four sides of the glass plate can be ground and polished simultaneously;

[0024] In addition, the four sides of the glass plate are all clamped by the polishing column one and the polishing column two. In the four directions of the glass plate, the opposite forces cancel each other out, realizing the positioning of the glass plate and making the glass plate fixed in the horizontal direction;

[0025] Third, the polishing column one and the polishing column two are respectively arranged at the upper and lower edges of the side of the glass plate, realizing the up-and-down positioning of the glass plate, and the up-and-down forces cancel each other out, weakening and even eliminating the internal stress suffered by the glass plate during the polishing process, which helps to protect the glass plate;

[0026] (2) A liquid box is provided in this solution. The polishing liquid is input to the side of the polishing column one through a micro pump and a liquid pipe, and has the following technical effects:

[0027] First, it can supply abrasive polishing liquid to both polishing column 1 and polishing column 2 simultaneously. The polishing liquid is drained through polishing column 1 to the upper edge of the glass plate, and then the polishing liquid flows to the lower edge. Since polishing column 1 is directly above polishing column 2, it promotes the polishing process.

[0028] Second, during the abrasive polishing process, it realizes the cooling effect of the glass plate, polishing column 1, and polishing column 2, avoiding the adverse effects of excessive frictional heat on the glass.

[0029] Third, polishing column 2 has a drainage effect. Since the bottom end of polishing column 2 faces the direction of the fixed cylinder, by setting the collecting trough plate, the collection of the polishing liquid is realized.

[0030] (3) In this solution, a buffer support structure is provided. On the one hand, it can help support the glass plate. On the other hand, through the action of the buffer spring and in cooperation with the transfer component, the sliding column can slide up and down in the fixed cylinder, which helps to adjust the height of the glass plate.

[0031] (4) A transfer component for transporting the glass plate is provided, which not only realizes the transportation process of the glass plate, but also, the vacuum suction cup is pressed on the glass plate to realize the positioning of the upper and lower surfaces of the glass plate.

[0063] Using the vacuum suction cups 51, the glass plate 12 is sucked and held, and under the action of the transfer assembly 15, the glass plate 12 is transported and released above the receiving plate 121 through the telescopic cylinder 10;

[0064] The adjusting motor 731 is started to make both the first polishing column 79 and the second polishing column 796 rotate by a certain angle to form a V shape, and the V-shaped opening faces the glass plate 12;

[0065] The telescopic cylinder 10 is started to drag the moving structure 14 and move the moving structure 14 towards the glass plate 12, so that the upper and lower edges of the glass plate 12 come into contact with the first polishing column 79 and the second polishing column 796;

On the other hand, through the action of the buffer spring 123 and in cooperation with the transfer assembly 15, the sliding column 122 can slide up and down in the fixed cylinder 124, which helps to adjust the height of the glass plate 12;

[0070] A transfer assembly 15 for transferring the glass plate 12 is provided, which not only realizes the transfer process of the glass plate 12, but also, the vacuum suction cup 51 is pressed on the glass plate 12 to realize the positioning of the upper and lower surfaces of the glass plate 12;

[0071] In this solution, the power systems can all be connected to the PLC controller for overall control of the work. Embodiment

Specifically, inclined splash-proof plates are provided on the four sides of the moving plate 3 to prevent the splash of the polishing agent solution caused by the high-speed rotation of several polishing columns. Therefore, the transfer assembly 15 in this solution plays a role in transferring the glass plate 12, and under the combined action of the moving plate 3 and the splash-proof plate 31, it has a splash-proof effect.

[0073] The technical features not described in the present invention can be realized by or adopt the prior art, and will not be elaborated here.
