Description

Technical Field

[0001] This utility model relates to the field of polishing machine technology, specifically to a stable glass cover polishing machine. Background Technology

[0002] Display terminals, such as mobile phones and tablets, have high quality requirements for their glass covers. They must not only be free of sharp edges and burrs, but also have good smoothness and flatness. Therefore, polishing is an essential process in the processing of glass covers, and it is also a very important process for the quality and appearance of the glass covers.

[0003] Conventional polishing processes typically involve a polishing wheel and a rotating base. The polishing wheel is positioned directly above, while the rotating base is below, with multiple glass cover plates held in place by suction cups. During polishing, the polishing wheel rotates to simultaneously polish multiple glass cover plates. After polishing one surface, the glass cover plate is flipped over to continue polishing the opposite surface.

[0004] To address the aforementioned issues, our company developed the first-generation glass cover polishing machine and applied for and obtained a national utility model patent (CN202322346096.4) for "Glass Cover Polishing Machine." However, customer feedback later indicated that while the product, through the meshing relationship between the two rotating wheels and the glass cover carrier, could cause the carrier to rotate at a certain speed during the polishing process, thereby improving the uniformity of polishing and further enhancing the polishing quality,… However, due to the polishing structure of the polishing machine, in order to meet the operation of the second polishing belt, the glass cover plate carrier cannot be equipped with a rotating shaft. In this way, relying solely on the meshing relationship between the two rotating wheels and the glass cover plate carrier will inevitably lead to an unreliable meshing relationship between the rotating wheels and the glass cover plate carrier, resulting in overload of the rotating wheel teeth. If either of the two gears fails, such as a broken tooth, the entire transmission system will immediately lose balance, the overturning torque will increase sharply, and it may cause the other gear to fail quickly as well, leading to catastrophic consequences such as damage to the gear plate. Utility Model Content

[0005] To solve the above problems and overcome the shortcomings of the existing technology, this utility model provides a stable glass cover polishing machine; The first technical problem to be solved is that, because the polishing structure of the polishing machine needs to accommodate the operation of the second polishing belt, the glass cover plate carrier cannot be equipped with a rotating shaft. In this way, relying solely on the meshing relationship between the two rotating wheels and the glass cover plate carrier will inevitably result in an unreliable meshing relationship between the rotating wheels and the glass cover plate carrier. The specific technical solution of this utility model to solve the above-mentioned technical problems is as follows: The stable glass cover plate polishing machine includes a housing; a polishing belt and a glass cover plate carrier are provided inside the housing; the polishing belt has two sections, including a first polishing belt and a second polishing belt; the glass cover plate carrier is attached to the top surface of the second polishing belt; the glass cover plate carrier is provided with multiple through holes suitable for accommodating glass covers and extending vertically; the first polishing belt is positioned directly above the glass cover plate carrier in a manner that allows for directional vertical movement and directional rotation; the second polishing belt is positioned directly below the glass cover plate carrier in a manner that allows for directional rotation. The characteristic feature is that: The outer side of the glass cover plate carrier is provided with three rotating wheels in a ring matrix in a triangular shape. The three rotating wheels mesh with the outer side of the glass cover plate carrier. The three rotating wheels include a first rotating wheel located on one side of the second polishing belt and two second rotating wheels located on the other side of the second polishing belt. The glass cover plate carrier plate located between the first rotating wheel and the second rotating wheel can simultaneously polish the top and bottom surfaces of the glass cover plate by rotating the first polishing belt and the second polishing belt when the first polishing belt moves down to the predetermined position. A support platform for supporting the glass cover is provided on the outer edge of the second polishing belt located between the second rotating wheels, and the support platform is on the same horizontal plane as the second polishing belt; The rotating wheel is rotatably connected and fixed to the horizontal fixed platform via a connecting seat. The shaft of the rotating wheel extends to the bottom of the horizontal fixed platform and is connected to a power structure for driving the three rotating wheels to rotate synchronously.

[0006] Furthermore, the power structure includes a drive sprocket fixedly connected to the shaft end of the rotating wheel.

[0007] Furthermore, the drive sprockets arranged in a triangular shape are engaged by a chain.

[0008] Furthermore, the chain between the adjacent drive sprockets is also provided with a tension sprocket.

[0009] Furthermore, the tension sprocket is directly or indirectly connected to the tension sprocket fixing bracket.

[0010] Furthermore, at least one of the tensioning sprockets is rotatably connected to the adjusting slider, which slides and locks in place on the tensioning sprocket fixing bracket via an adjusting screw.

[0011] Furthermore, one of the drive sprockets is a driving sprocket, which is connected to the output section of the output unit via a key connection.

[0012] The beneficial effects of this utility model are: One advantage of this utility model is that the outer side of the glass cover plate carrier is provided with three rotating wheels arranged in a ring matrix in a triangular shape. This solves the problem that because the polishing structure of the polishing machine requires the second polishing belt to operate, the glass cover plate carrier cannot be equipped with a rotating shaft. In this case, relying solely on the meshing relationship between the two rotating wheels and the glass cover plate carrier will inevitably lead to an unreliable meshing relationship between the rotating wheels and the glass cover plate carrier. One advantage of this utility model is that it provides a support platform for supporting the glass cover plate on the outer edge of the second polishing belt located between the second rotating wheels, which solves the problem that part of the glass cover plate carrier plate is suspended in the air due to the three rotating wheels being arranged in a ring matrix in a triangular shape. One advantage of this invention is that it provides a tension sprocket that is rotatably connected to an adjusting slider. The adjusting slider slides on the tension sprocket fixing bracket and is locked in place by an adjusting screw, resulting in higher transmission efficiency and maintaining consistent rotation of each gear.
