Description
Technical Field
[0001] This utility model belongs to the field of glass processing technology. Specifically, this utility model relates to a photovoltaic glass hole edge grinding mechanism. Background Technology
[0002] In the backplate drilling process of glass deep processing, the inner ring of the hole is rough and burrs are generated. There are also some edge breakages. Under a microscope, the irregularity and size of the edge breakage can be clearly observed. The product cannot pass the standard requirements of the four-point bending strength test.
[0003] Currently, a chamfering machine is used to hold the grinding head and rotate it to grind the edge of the hole. However, the glass is not very stable during grinding, resulting in poor edge grinding effect. In addition, the grinding process generates high temperatures, which may cause glass breakage or other damage.

The main column assembly is made of rectangular steel tubing, divided into upper and lower columns, with a connecting shaft between the two columns. The upper column can be raised and lowered by a cylinder. A rotating shaft is located at the top of the upper column, and a swing arm A is mounted on the rotating shaft. The other end of swing arm A is hinged to swing arm B by a hinge shaft, and the other end of swing arm B is hinged to swing arm C by a hinge shaft. A handle is located at the other end of swing arm C, and a motor is fixed to the side of swing arm C. The grinding wheel structure consists of a grinding wheel with guide plates on both sides, and the grinding wheel is fixed to the motor shaft. The upper column of the main column assembly rises and falls with the cylinder push rod, and the grinding wheel rises and falls with the upper column. This glass inner hole grinding device does not solve the aforementioned technical problem. Utility Model Content

[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this invention, and to facilitate its implementation.
[0022] like Figure 1 and Figure 2 As shown, the photovoltaic glass hole edge grinding mechanism includes a chamfering machine 1, which includes a drive motor 11. The output end of the drive motor 11 is connected to a grinding head 13. A camera 12 is provided on one side of the drive motor 11. It also includes a conveyor belt 2, which includes a frame 21 and a conveyor roller 22. A cylinder 3 is provided above the conveyor belt 2. The output end of the cylinder 3 is connected to a positioning block 31. One end of the bottom of the positioning block 31 is provided with a through hole 32, which is located below the grinding head 13.
[0023] The existing chamfering machine 1 operates as follows: the glass 4 runs along the conveyor roller 22. When the hole 41 is along the conveyor belt 2, the camera 12 takes a picture to determine the coordinates and center of the hole 41. Then, the chamfering machine 1 moves the grinding head 13 to the coordinates provided by the camera 12, and the chamfering machine 1 moves the drive motor 11 down and starts the drive motor 11, and the grinding head 13 begins grinding. In this application, a mechanism for stabilizing the glass position is installed on one side of the existing chamfering machine 1. During the operation of the chamfering machine 1, the piston rod driven by the cylinder 3 drives the positioning block 31 to press the glass down, thereby stabilizing the glass position. Furthermore, the grinding head 13 grinds the edge inside the through hole 32, ensuring the stability of the inner ring grinding and chamfering process of the glass hole. After the positioning block 31 is provided with the through hole 32, the end of the positioning block 31 forms a square frame structure, which can temporarily buffer the coolant. The coolant is difficult to flow out from the square frame to the outside, so that the coolant is mainly concentrated in the through hole 32 and located around the glass hole. This not only improves the cooling effect of the coolant, but also reduces the amount of coolant used, which helps to reduce production costs. The size of the through hole 32 and the diameter of the drain pipe 37 are much larger than the size of the glass hole and the grinding head 13, so they will not hinder the spatial movement of the grinding head 13. The through hole 32 is a square structure. Designing the through hole 32 as a square hole is simpler to manufacture. Compared with a round hole, it can hold more coolant and improve cooling efficiency.
[0024] like Figure 3-1 and Figure 3-2As shown, the positioning block 31 has an L-shaped structure and a cooling pipe inlet 33. An opening 34 is located inside the through hole 32 on the positioning block 31, and the cooling pipe inlet 33 communicates with the opening 34. The side of the positioning block 31 is used to connect with the piston rod of the cylinder 3, and the cooling pipe inlet 33 is used to connect with the cooling pipe. The connection is simple and convenient. Coolant is transported from the opening 34 to the through hole 32 area through the internal connection of the positioning block 31. Compared with the conventional method of using a jet-type coolant spray pipe, there is no splashing, effectively protecting surrounding components and reducing coolant consumption. The positioning block 31 not only stabilizes the glass position but also serves as a coolant flow channel. Its simple structure reduces the number of components used. Reinforcing ribs 36 are also provided on both sides of the positioning block 31 to improve the structural strength at its bends.
[0025] like Figure 4-1 and Figure 4-2 As shown, the grinding head 13 is provided with grinding grooves 14, which are distributed circumferentially and have a U-shaped or V-shaped cross-section. The grinding head 13 with the above-mentioned grinding groove 14 structure can grind the upper and lower sides of the glass hole simultaneously, which facilitates the formation of a chamfer structure and removes burrs and other defects from the inner circle of the hole, thereby ensuring that the four-point bending of the glass meets the standard requirements.
[0026] like Figure 1 As shown, a drain pipe 37 is provided below the positioning block 31. Both the chamfering machine 1 and the cylinder 3 are mounted above the conveyor rollers 22 via crossbeams 23. The drain pipe 37 is installed between the two conveyor rollers 22 via crossbeams 23 fixed between the frames 21. The drain pipe 37 is designed below the through hole 32. During the cooling process, most of the coolant will enter the drain pipe 37 along the holes 41 in the glass, which is convenient for collection, conducive to resource recycling, ensures a friendly workshop environment, and reduces the accumulation of coolant on the glass, thus reducing the burden of subsequent cleaning work.
[0027] like Figure 1 As shown, a light-blocking plate 25 is provided above the conveyor belt 2. The light-blocking plate 25 can block ambient light to ensure that the camera 12 can observe clearly.
[0028] like Figure 1 As shown, the conveyor belt 2 is also equipped with a guide roller 24. The guide roller 24 and the conveyor roller 22 work together to guide the glass and prevent it from tilting during transport.
[0029] like Figure 3-1 and Figure 3-2 As shown, a rubber buffer pad 35 is provided at the bottom of the positioning block 31. The rubber buffer pad 35 plays a buffering role to prevent the glass from being damaged due to excessive driving pressure from the cylinder 3.
[0030] The working process is as follows: When glass 4 is conveyed along conveyor belt 2, camera 12 detects the hole position and stops conveyor belt 2. Cylinder 3 starts and moves positioning block 31 down to press down the glass. At this time, hole position 41 is located between through hole 32 and drain pipe 37. At the same time, chamfering machine 1 starts and moves grinding head 13 down to the same height position as hole position 41. The internal moving module of chamfering machine 1 moves grinding head 13 circumferentially along the edge of hole position, so that the edge of hole position 41 is evenly ground by grinding head 13. At the same time, cooling pipe delivers coolant to cool the process. Most of the coolant is discharged with drain pipe 37 and will not accumulate on the glass surface. After the above operations are completed, each mechanism is reset or stopped to prepare for the next glass hole edge grinding.
[0031] The photovoltaic glass hole edge grinding mechanism stabilizes the glass position by pressing down the positioning block 31 driven by the cylinder 3, ensuring stable posture during glass hole edge grinding. It also has a reasonably structured cooling channel on the positioning block 31, which meets the cooling requirements during glass edge grinding, avoids damage to the glass due to excessive temperature, and improves the cooling effect while reducing the amount of coolant used.
[0032] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
