Description

Technical Field

[0001] This utility model relates to the field of automated glass polishing equipment, and in particular to a gas-liquid integrated suction plate mechanism. Background Technology

[0002] The glass sheet involved in this utility model is mainly used in electronic terminals, especially mobile phones, tablets and other electronic products. During grinding, the glass sheet needs to be adsorbed on the suction plate and continuously sprayed with grinding fluid. In existing grinding disc devices, the vacuuming and grinding fluid spraying are set as two independent mechanisms. The vacuuming mechanism is set on the suction plate, while the grinding fluid is set next to the suction plate and sprayed at an angle towards the suction plate. This spraying method results in uneven spraying of the grinding fluid, which affects the grinding effect of the glass sheet and thus increases the defect rate. At the same time, due to the uneven spraying, the amount of grinding fluid sprayed needs to be increased to cover the insufficient areas of grinding fluid, which leads to a significant increase in the amount of grinding fluid used, thereby increasing the production cost. Utility Model Content

[0003] The purpose of this invention is to overcome the technical problems of complex structure and uneven spraying of grinding liquid in existing suction discs, and to provide a suction disc mechanism with integrated vacuum suction and grinding liquid spraying, compact structure and good spraying effect.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A vapor-liquid integrated suction plate mechanism includes: a discharge plate, wherein a vacuum chamber is provided inside the discharge plate, and a plurality of suction holes and spray holes are provided on the upper mounting surface of the discharge plate, wherein the suction holes are connected to the vacuum chamber; a connecting flange, wherein the connecting flange is provided with a grinding fluid connection hole and a vacuum connection structure; a first rotating shaft, wherein the first rotating shaft is a hollow structure and is connected to the discharge plate through the connecting flange; and a second rotating shaft, wherein the second rotating shaft is provided with a vacuum channel, the second rotating shaft is connected to the connecting flange and located inside the first rotating shaft, wherein a gap is left between the inner wall of the first rotating shaft and the second rotating shaft to form a grinding fluid flow channel, wherein the grinding fluid flow channel is connected to the spray holes through the grinding fluid connection hole, and the vacuum channel is connected to the vacuum chamber through the vacuum connection structure.

[0005] Compared with the prior art, this utility model sets the first rotating shaft for conveying the grinding fluid and the second rotating shaft for vacuum suction on the same axis, so that the grinding fluid can be sprayed directly from the template and evenly distributed throughout the template, thereby solving the problem of uneven spraying of the existing grinding fluid. At the same time, the integrated setting of spraying and vacuum suction makes the whole mechanism simpler and easier to assemble and maintain, thereby improving production efficiency.

[0006] Furthermore, the feeding tray includes an upper feeding tray and a lower feeding tray. The upper feeding tray is provided with a plurality of suction holes and spray holes, and the lower feeding tray is provided with a conical inclined surface with a through hole in its middle. The conical inclined surface slopes from the periphery of the lower feeding tray toward the through hole. The upper feeding tray is placed on the lower feeding tray and closes the conical inclined surface to form the vacuum cavity. The cooperation between the upper feeding tray and the lower feeding tray to close and form the vacuum cavity simplifies the overall structure, reduces processing and maintenance costs, and ensures the sealing reliability of the vacuum environment.

[0007] Furthermore, the connecting flange includes a connecting portion and a connecting boss disposed on the connecting portion. The lower end of the connecting portion is provided with a first connecting end and a second connecting end coaxially disposed. The grinding fluid connecting hole penetrates the connecting portion and the connecting boss and communicates with the first connecting end. The connecting boss has a cavity in the middle, which communicates with the second connecting end. The side wall of the connecting boss is provided with a plurality of vacuum connecting holes, which communicate with the cavity to form the vacuum connecting structure. The first rotating shaft is connected to the first connecting end, and the second rotating shaft is connected to the second connecting end. This structure, through the coaxial arrangement of the first and second connecting ends, achieves the integration and compact layout of the grinding fluid delivery channel and the vacuum channel, significantly reducing the overall space occupied and improving the structural rigidity and assembly convenience of the equipment. The combination of the concave cavity and multiple vacuum connection holes forms a distributed vacuum connection structure, effectively improving the uniformity and reliability of vacuum adsorption.

[0008] Furthermore, for ease of installation, the connecting flange and the first rotating shaft are an integral structure.

[0009] Furthermore, a second connecting flange is provided at one end of the second rotating shaft, and an installation step is provided in the cavity. The second rotating shaft passes through the second connecting end so that the second connecting flange is installed on the installation step. The second rotating shaft is fixedly connected by the connecting flange. Since the flange can be processed separately and then fixedly connected to the second rotating shaft, the production and processing are more convenient, and the installation of the second connecting flange and the second rotating shaft is also relatively simple.

[0010] Furthermore, it also includes a first rotary joint and a second rotary joint. The rotating shaft of the first rotary joint is connected to the first rotating shaft, and the inlet of the first rotary joint is connected to an external grinding fluid supply source. The rotating shaft of the second rotary joint is connected to the second rotating shaft, and the inlet of the second rotary joint is connected to an external vacuum source. Through the structural characteristic of the rotary joint rotating at one end while the other end does not rotate, the installation requirement that the first and second rotating shafts rotate while the external connection end cannot rotate can be effectively solved.

[0011] Furthermore, the connecting flange includes a connecting portion and a connecting boss disposed on the connecting portion. The lower end of the connecting portion has a first connecting end and a second connecting end coaxially arranged. The grinding fluid connecting hole penetrates the connecting portion and the connecting boss and communicates with the first connecting end. A cavity is provided in the middle of the connecting boss, which communicates with the second connecting end. Several vacuum connecting holes are provided on the side wall of the connecting boss, and these vacuum connecting holes communicate with the cavity to form the vacuum connecting structure. The first rotating shaft is sealed to the first connecting end, the second rotating shaft is sealed to the second connecting end, the lower discharge tray is sealed to the connecting portion, and the connecting boss passes through the through hole and is sealed to the upper discharge tray. The connecting flange cleverly and reasonably seals the discharge tray, the first rotating shaft, and the second rotating shaft together. This connecting flange structure, through a multi-seal connection design, achieves complete sealing and isolation between the grinding fluid conveying channel, the vacuum channel, and the rotating components, thoroughly avoiding cross-contamination and pressure leakage between different media, and significantly improving the system's operational reliability and stability.

[0012] Furthermore, to facilitate the assembly and disassembly of the upper and lower feeding trays, the upper feeding tray has several upper latches on its peripheral wall, and the lower feeding tray has a corresponding latching handle on its peripheral wall, along with a pull ring on the latching handle. After the upper and lower feeding trays are assembled, the pull ring can be fitted onto the latches, and by swinging the latching handle downwards, the pull ring applies a downward force to the upper latches. This quick-release assembly has a simple structure, is easy to operate, and is low in cost.

[0013] Furthermore, to prevent wobbling when the first and second rotating shafts rotate, a first retaining sleeve and a second retaining sleeve are specially provided. The first retaining sleeve is disposed on the first rotating shaft, and the second retaining sleeve is disposed on the second rotating shaft. The first retaining sleeve includes a mounting sleeve, a bearing, and a fixing part disposed on the outer periphery of the mounting sleeve. The bearing is disposed on both sides of the mounting sleeve, and the first rotating shaft passes through the mounting sleeve so that the bearing is fitted onto the first rotating shaft.
