[0002] The popularity of smart electronic devices, especially the design of curved screens and curved glass back panels, has spawned a series of glass finishing industries centered on glass polishing. During the glass polishing process, a polishing liquid with polishing powder added is required. After polishing, a portion of the polishing liquid mixed with glass residue will remain on the glass surface, which needs to be removed before entering the next process. In this automated glass polishing equipment, it is necessary to supply liquid to the polishing head and supply air to the polishing liquid blowing mechanism. The traditional spindle of the glass polishing equipment cannot meet the requirements of supplying liquid and air to multiple stations at the same time. To solve this problem, the current method is to increase the spindle size and increase the processing steps, but this solution will inevitably lead to the problem of a larger spindle weight, a slower and more cumbersome spindle processing process, and it is difficult to meet the processing accuracy requirements, resulting in a low yield rate.

[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

When a component is referred to as being "connected to" another component, it may be directly connected to the other component or there may be a central component at the same time.

[0019] It should also be noted that the directional terms such as left, right, up, and down in the embodiments of the present invention are merely relative concepts or are based on the normal use status of the product and should not be considered as restrictive.

[0020] Please refer to Figures 1 to 5 The present invention proposes a rotating spindle 100 for a glass polishing device and a glass polishing device using the rotating spindle 100, wherein the rotating spindle 100 has a first annular side wall 110 extending in the axial direction, and a first cavity 200 is formed inside the first annular side wall 110; the rotating spindle 100 also has a second annular side wall 120 extending in the axial direction and located outside the first annular side wall 110, and a second cavity 300 is formed between the first annular side wall 110 and the second annular side wall 120; a reinforcing rib 130 extending in the axial direction of the rotating spindle 100 is also provided between the first annular side wall 110 and the second annular side wall 120, and the reinforcing rib 130 is a connecting piece connecting the first annular side wall 110 and the second annular side wall 120; the first annular side wall 110, the second annular side wall 120 and the reinforcing rib 130 are integrally formed.

[0021] The rotating spindle 100 of the glass polishing device is used to install the grinding head and the suction cup. In the glass polishing device with multiple polishing stations, multiple grinding heads are arranged side by side along the axis of the spindle on the rotating spindle 100, which is used to polish multiple glass plates at the same time. The rotating spindle 100 is also provided with multiple suction cups parallel to the grinding heads arranged side by side, which are used to absorb the glass plate to the polishing station or absorb it from the polishing station to the next station. When polishing the glass, the glass plate needs to be immersed in the polishing liquid. The glass polishing device in this embodiment adopts the method of supplying the polishing liquid through the grinding head. The grinding head is installed on the rotating spindle 100, and the liquid supply system supplies liquid to the grinding head.

[0022] The first cavity 200 of the rotating spindle 100 proposed in a specific embodiment of the present invention is connected to the liquid supply system, and the second cavity 300 is connected to the air supply system. The rotating spindle 100 can be regarded as a part of the liquid supply system and the air supply system, supplying liquid and air to the grinding head and the suction cup. Similarly, the rotating spindle 100 can also be regarded as a component independent of the liquid supply system and the air supply system, and interfaces of the liquid supply system and the air supply system are provided at the end of the rotating spindle 100, so that the first cavity 200 is connected to the liquid supply system, and the second cavity 300 is connected to the air supply system. Among them, the second cavity 300 includes a plurality of independent sub-cavities divided by the reinforcing ribs 130, and each of the sub-cavities is connected to the air supply system.

[0023] The spindle of multiple polishing stations is relatively long, and the traditional spindle turning and milling processing cannot meet the requirements of liquid and air supply at the same time. In addition, the axial torsion error is large, and the consistency of the grinding head installation position cannot be guaranteed, which easily leads to the problem of inconsistent glass plates thrown out when multiple polishing stations are working. In order to ensure the axial accuracy while meeting the requirements of the spindle being able to supply liquid and air at the same time, the rotating spindle 100 proposed by the present invention is processed by aluminum pressing technology, and aluminum alloy is used for one-time extrusion molding.

[0024] In order to open a grinding head installation position and a suction cup installation position on the rotating spindle 100 formed in one step by the aluminum extrusion process, the present invention sets the second annular side wall 120 to be square with four sides, the outer side of the second annular side wall 120 is the outer side of the rotating spindle 100, and the second openings 121 arranged in sequence are opened on the two sides thereof, and the first openings 111 are opened at the position of the first annular side wall 110 corresponding to the position of each second opening 121, and each first opening 111 and each corresponding second opening 121 form a grinding head interface 400, connecting the first cavity 200 and the second cavity 300. In this embodiment, the grinding head interface 400 includes an air supply interface and a liquid supply interface, that is, it can realize the supply of liquid and air to the grinding head; in other embodiments where the grinding head does not need to be supplied with air, it is also possible to only supply liquid to the grinding head by opening only a liquid inlet channel at the installation position of the grinding head, and setting a sealing component to seal the second opening 121 formed by the second cavity 300, while ensuring that the interface has good sealing performance.

[0025] On the second side wall, on a side different from the side where the grinding head interface 400 is arranged, a third opening is arranged in parallel to communicate with the second cavity 300 . The third opening forms a suction cup interface 500 for installing a suction cup assembly.

[0026] The first annular sidewall 110 is set in a circular shape, the second annular sidewall 120 can be set in a circular shape or a square shape, and multiple groups of reinforcing ribs 130 are provided. When the second annular sidewall 120 is set in a square shape, the reinforcing ribs 130 are provided on the first annular sidewall 110, and at least one reinforcing rib 130 is connected to the side plate of the second annular sidewall 120, and at least one reinforcing rib 130 is connected to the corner of the second annular sidewall 120. In a preferred embodiment, eight reinforcing ribs 130 are provided, respectively connecting the four side plates and the four corners of the second sidewall; when the second annular sidewall 120 is set in a circular shape, multiple groups of reinforcing ribs 130 are evenly distributed between the first annular sidewall 110 and the second annular sidewall 120. In other embodiments, the first annular sidewall 110 and the second annular sidewall 120 can also be set in a square shape, and the four side plates of the first annular sidewall 110 and the four side plates of the second annular sidewall 120 are respectively arranged in parallel. When the second annular side wall 120 is configured to be square, chamfered structures are provided at four corners of the second annular side wall 120 .
