Description

Technical Field

[0001] This utility model belongs to the technical field of graphite photovoltaic boat processing equipment, and in particular relates to automated processing equipment for surface polishing of graphite photovoltaic boats. Background Technology

[0002] In the photovoltaic industry, graphite photovoltaic boats are key components that support silicon wafers for processes such as coating. The surface smoothness of these boats directly affects the processing quality and production efficiency of the silicon wafers. A Chinese patent application with publication number 202010326033.0 discloses a high-precision polishing device for graphite slices, including a frame, a worktable, and a polishing assembly. The device uses small holes on the worktable surface for vacuum adsorption and fixation of the graphite slices. Double slide rails and the polishing assembly on the frame adjust the polishing position, initially achieving high polishing precision. An annular channel connected to the small holes enhances the vacuum adsorption effect. This invention also improves the stability of the polishing assembly and further enhances polishing precision through a three-layer structure design consisting of a metal layer, a rubber layer, and a polishing layer on the polishing disc. Although this patent has the advantages of high safety and easy replacement of the polishing layer, it still has the disadvantage of low polishing efficiency. After polishing one side, it is necessary to flip the machine. This process not only requires stopping the machine, but also requires manual intervention or reliance on a complex flipping mechanism, resulting in interruption of the processing flow and poor continuity of equipment operation. It can only polish one surface of the graphite photovoltaic boat at a time. To complete double-sided polishing, two independent clamping and polishing processes are required, which greatly increases the processing time and makes the polishing efficiency low. To address these issues, we provide automated processing equipment for polishing the surface of graphite photovoltaic wafers. Utility Model Content

[0003] The purpose of this invention is to provide an automated processing equipment for polishing the surface of graphite photovoltaic boat sheets. By cooperating with the positioning component and the polishing component, it solves the problem that the existing graphite photovoltaic boat sheet polishing equipment has a single polishing structure and requires a flipping operation after polishing one side, resulting in low polishing efficiency.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0005] This utility model relates to an automated processing equipment for polishing the surface of graphite photovoltaic wafers. It includes a processing chamber, with polishing components installed at the top and bottom of the chamber's inner cavity. Positioning components are installed on both sides of the inner cavity. A support frame is fixedly connected to the bottom of the processing chamber. Each polishing component includes a drive motor, which is fixedly connected to one side of the processing chamber. A drive screw is fixedly connected to the output end of the drive motor. An adjusting seat is threaded onto the surface of the drive screw. An adjusting motor is fixedly connected to the back of the adjusting seat. An adjusting screw is fixedly connected to the output end of the adjusting motor. A threaded sleeve is threaded onto the surface of the adjusting screw. A mounting plate is fixedly connected to one side of the threaded sleeve. An electric push rod is fixedly connected to one side of the mounting plate. A connecting disc is fixedly connected to the telescopic shaft of the electric push rod. A polishing motor is fixedly connected to one side of the connecting disc. A polishing disc is fixedly connected to one end of the output shaft of the polishing motor.

[0006] The present invention is further configured such that the positioning component includes a guide rail, one side of which is fixedly connected to the inner wall of the processing chamber, and one side of which is movably connected to a positioning frame via a slider. The top of the positioning frame is threadedly connected to a clamping screw, and the bottom of the clamping screw is movably connected to a pressure plate. When the graphite photovoltaic boat is inserted into the inner cavity of the two positioning frames, the clamping screw is rotated, and the clamping screw drives the pressure plate to move downward until its bottom abuts against the top of the graphite photovoltaic boat, thereby fixing the graphite photovoltaic boat in the inner cavity of the two positioning frames.

[0007] The present invention is further configured such that a dust collection box is fixedly connected to one side of the mounting plate, a filter screen is provided in the inner cavity of the dust collection box, a fan is provided on one side of the dust collection box, and a dust suction disc is fixedly connected to one side of the mounting plate through a connecting rod. One side of the dust suction disc is connected to the dust collection box through a dust suction pipe. The dust suction disc sucks the dust generated during the polishing process into the inner cavity of the dust collection box, and the filter screen filters the dust in the inner cavity of the dust collection box, preventing polishing dust from affecting the processing environment.

[0008] The present invention is further configured such that a telescopic rod is fixedly connected to the side of the mounting plate facing the connecting plate, and the end of the telescopic rod away from the mounting plate is fixedly connected to the surface of the connecting plate. The telescopic rod extends and retracts as the connecting plate moves up and down. The limiting effect of the two telescopic rods improves the movement stability of the connecting plate and the polishing motor on one side.

[0009] The present invention is further configured such that a connecting frame is fixedly connected to the back of the adjusting seat, and the back of the connecting frame contacts the inner wall of the processing chamber. The connecting frame connects the upper and lower adjusting seats into an integral structure, thereby ensuring that the upper and lower polishing components move synchronously.

[0010] The present invention is further provided that a protective door is provided on the front of the processing chamber, and a handle is fixedly connected to the front of the protective door. Closing the transparent protective door can protect the inner cavity of the processing chamber, and the protective door is easy to open.

[0011] The present invention is further configured such that a storage box is fixedly connected to the bottom of the inner cavity of the support frame, and a drawer is provided in the inner cavity of the storage box. By pulling out the drawer of the inner cavity of the storage box, the graphite photovoltaic boat workpiece can be placed in the drawer, which can save the trouble of going back and forth to retrieve the workpiece.

[0012] The present invention is further configured such that limit rods are fixedly connected to the top and bottom of both sides of the inner cavity of the processing chamber, and the limit rods are connected through the adjusting seat. The adjusting seat moves on the surface of the limit rods, and the limiting action of the limit rods can improve the movement stability of the adjusting seat.

[0013] The present invention has the following beneficial effects.

[0014] 1. This utility model, through its upper and lower double polishing disc structure design, can polish both the upper and lower surfaces of graphite photovoltaic wafers simultaneously without pausing the equipment for flipping during processing. This effectively solves the problem of traditional equipment requiring interruption for flipping, and significantly improves the continuity of equipment operation and processing efficiency.

[0015] 2. This utility model requires only one clamping. After fixing the graphite photovoltaic boat sheet in the inner cavity of the positioning frame, it is pushed into the processing chamber, and double-sided polishing can be completed simultaneously. This reduces one clamping and polishing process, significantly reducing processing time and costs. In addition, this utility model also integrates a dust treatment function. Through the cooperation of a fan, a dust collection plate, and a dust collection box, it can absorb and filter the dust generated during polishing in real time, avoiding dust pollution of the processing environment and improving the working environment.
