[0057] The present disclosure will be further described in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are merely exemplary and are not limiting to the disclosure. In addition, it should be noted that only parts related to the present disclosure are shown in the drawings for the purpose of description.
[0058] It should be noted that the embodiments and features in the embodiments of the present disclosure can be combined with each other without conflict.

Therefore, unless otherwise specified, the features of various embodiments / examples can be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of the present disclosure.
[0060] In the drawings, cross-hatching and / or shading are generally used to make the boundaries of adjacent components clear. As such, unless otherwise specified, the presence of cross-hatching or shading is not meant to imply that a particular material, material property, dimension, ratio, etc. is being represented in any way. In addition, for clarity and / or descriptive purposes, the dimensions and / or relative dimensions of the components shown in the figures can have been exaggerated or can otherwise not be drawn to scale. When exemplary embodiments can be practiced differently, a specific process sequence can be performed in a different order than the described sequence. For example, two consecutively described processes can be performed at substantially the same time or in the reverse order of the described sequence. Moreover, the same reference numerals are used to represent the same components throughout the specification and figures.
[0061] When a component is referred to as being "on" or "on top of", "connected to", or "coupled to" another component, it can be directly on, directly connected to, or directly coupled to the other component, or intervening components can be present.

[0077] In the present disclosure, the support frame 145 is further provided with a second driving device 147, which is used to drive the suction assembly 146 to rotate around the central axis with respect to the support frame 145, that is, the second driving device 147 is used to drive the suction assembly 146 to rotate.
[0078] Moreover, the preset rotation axis and the central axis of the suction assembly 146 form an angle, which is greater than 0° and less than or equal to 90°. Preferably, the preset rotation axis and the central axis of the suction assembly 146 are substantially perpendicular, and the preset rotation axis and the central axis of the suction assembly 146 are not in the same plane.
[0079] Overall, the suction device 140 of the present disclosure can include a lifting driving device 141, a support plate 142, a movable support plate 143, a first driving device 144, a support frame 145, a suction assembly 146, a second driving device 147, and a pressure detection assembly 148.
[0080] When the suction device 140 is symmetrically arranged, the preset rotation axes of the two suction devices 140 can coincide, and the central axes of the suction assemblies 146 of the two suction devices 140 can be parallel.
[0081] In a preferred embodiment, the suction assembly 146 of the present disclosure can include a rotating shaft component 146A and a suction nozzle 146B, wherein the rotating shaft component 146A is rotatably arranged on the support frame 145 and has a central hole. In an embodiment, a driven pulley can be arranged on the rotating shaft component 146A, and a driving pulley can be arranged on the output shaft of the second driving device 147. The driving pulley and the driven pulley can be connected by a synchronous belt.
[0082] The suction nozzle 146B is detachably arranged on the rotating shaft component 146A. Moreover, the end of the suction nozzle 146B away from the rotating shaft component 146A can be formed as a recess, and the glass can be adsorbed and positioned in the recess. In a preferred embodiment, the depth of the recess is less than the thickness of the glass, so that the glass exposed outside the recess can be polished.
[0083] That is, when a negative pressure is provided to the upper end of the rotating shaft component 146A, the negative pressure can be provided to the recess via the central hole of the rotating shaft component 146A and the central hole of the suction nozzle 146B, so that the glass can be adsorbed in the recess. The central hole of the suction nozzle 146B can be in communication with the recess.
[0084] The pressure detection assembly 148 of the present disclosure is used to detect the pressure of the workpiece during polishing. Specifically, when the workpiece is polished, the suction assembly 146 can generate rotation around the preset rotation axis, and the support frame 145 will apply pressure to the pressure detection assembly 148, which can detect the pressure.
[0085] Specifically, the pressure detection assembly 148 of the present disclosure can include a bracket 148A, a contact block 148B, a guide 148C, a pressure sensor 148D, and an elastic component 148E.
[0086] The support 148A is fixed to the movable base plate 130, and the upper end of the support 148A is inclined, thereby facilitating the contact between the support frame 145 and the contact block 148B.
[0087] The support 148A is fixed to the movable base plate 130, and the upper end of the support 148A is inclined, thereby facilitating the contact between the support frame 145 and the contact block 148B.
[0088] The contact block 148B is used to contact the support frame 145, and the support frame 145 is used to apply pressure to the contact block 148B; thus, in the present disclosure, after the contact block 148B is subjected to pressure, it can generate a motion approaching the support 148A, and when the pressure on the contact block 148B disappears, the contact block 148B can generate a motion away from the support 148A under the elastic force of the elastic component 148E.
[0089] The guide 148C is provided on the contact block 148B, and the guide 148C is slidably provided in the guide hole of the support 148A; in a preferred embodiment, the guide 148C can be a screw rod with a threaded section, wherein the screw rod passes through the guide hole and is screwed into the threaded hole on the contact block 148B, at this time, the middle part of the screw rod will cooperate with the inner wall surface of the guide hole to realize the motion guidance of the contact block 148B. Moreover, by cooperating the screw head of the screw rod with the support 148A, the maximum motion of the contact block 148B away from the support 148A can be limited, thereby preventing the contact block 148B from being separated from the support 148A.
