Description

A sharp grinding tool for photovoltaic modules

technical field

The utility model relates to a grinding tool, in particular to a grinding tool with sharp corners for photovoltaic components.

Background technique

With the improvement of people's living standards and economic growth, the global energy consumption has declined sharply. Facing the problem of energy shortage, the development and development of new energy sources will be imperative, and the inexhaustible solar energy will become one of the hottest new industries. Crystalline silicon solar cell modules are currently the most efficient and widely used in the photovoltaic industry.

Usually crystalline silicon solar cell modules use aluminum frames to improve mechanical properties, however, during the framing process of crystalline silicon solar cell modules, due to the dimensional error of the framing equipment and the aluminum profiles themselves, there will be slight misalignment at the corners of the aluminum profiles , The corners of crystalline silicon solar cell modules will form different degrees of sharp surfaces, which will pose a great threat to the personal safety of operators in the process of cleaning, handling, and installation in the future. In order to solve the sharp corners of crystalline silicon solar cell components and reduce safety accidents. Generally, after cleaning the crystalline silicon solar cell modules, special tools are used to polish the corners to make them smooth.

At present, the corners of each crystalline silicon solar cell module are generally polished manually with a file, but this grinding method has the following defects:

(1) Because each cleaned crystalline silicon solar cell module needs to be polished one by one, it increases a lot of working time and reduces the overall production efficiency;

(2) Since this grinding method is manual operation, the consistency of grinding is very poor;

(3) Since there is no other protective device during grinding, the file can easily scratch the profile of the crystalline silicon solar cell module, resulting in the unqualified profile of the cell component;

(4) The corner gap of crystalline silicon solar cell modules is one of the important indicators to measure the qualification of crystalline silicon solar cell modules in the appearance inspection of crystalline silicon solar cell modules, but using a file to polish the corners of crystalline silicon solar cell modules can easily cause If the site is polished too deeply, the gap between the corners of the crystalline silicon solar cell modules will be too large, resulting in unqualified products.

Utility model content

The purpose of the utility model is to overcome the shortcomings and deficiencies of the above-mentioned prior art, provide a sharp grinding tool for photovoltaic modules, and solve the problems of low efficiency, poor aesthetics after grinding, and easy occurrence of failures caused by manual grinding with a file. product shortcomings.

The purpose of this utility model is achieved through the following technical solutions: a sharp grinding tool for photovoltaic modules, including a motor and a file. An edge protector, the cross section of the edge protector is L-shaped, the two wings of the edge protector form an included angle α, and a cavity is provided at the junction of the two wings, the file is located in the cavity, and the cavity is at the end facing the opening of the included angle α A notch is provided through which a portion of the file protrudes.

Further, the surface of the above-mentioned edge protector is covered with a layer of protective film, and when the edge protector is in contact with the aluminum frame of the crystalline silicon solar cell module, the crystalline silicon solar cell module will not be scratched, thereby reducing failures caused by scratches on the aluminum frame.

A handle is provided on the end of the above-mentioned edge protection facing the tip of the included angle α, and the handle is arranged on the intersection line of the two wings of the edge protection.

The above-mentioned included angle α is 90°.

The beneficial effects of the utility model are:

(1) The grinding tool is electric grinding, which increases the grinding speed and improves the production efficiency;

(2) This grinding tool can polish the whole set of crystalline silicon solar cell modules at the same time, which saves a lot of operating time compared with manually polishing each crystalline silicon solar cell module one by one;

(3) Since it is machine-polished, the degree of grinding at the sharp corners will be very consistent, avoiding excessive grinding, resulting in unqualified phenomena such as excessive gaps in the corners of crystalline silicon solar cell modules;

(4) Since the surface of the grinding tool is covered with a very thin protective film, when the grinding tool is in contact with the aluminum frame of the crystalline silicon solar cell module, it will not scratch the crystalline silicon solar cell module, reducing damage caused by scratches on the aluminum frame failed.

Detailed ways

Below in conjunction with embodiment the utility model is described in further detail, but the structure of the utility model is not limited to the following examples:

【Example】

As shown in Figure 1, Figure 2, and Figure 3, a sharp grinding tool for photovoltaic modules includes a motor 1 and a file 2. The file 2 is in the shape of a circular column and is installed on the shaft 3 of the motor 1. The outside of the file 2 is provided with a guard 4, the cross section of the guard 4 is L-shaped, the two wings of the guard 4 form an angle α, and a cavity 5 is provided at the junction of the two wings, and the file 2 is located in the cavity 5 Inside, the cavity 5 is provided with a notch 6 at one end opening toward the included angle α, and a part of the file 2 protrudes from the notch 6 .

Further, the above-mentioned edge protector 4 is made of aluminum profile, and its surface is covered with a layer of protective film. When the edge protector 4 is in contact with the aluminum frame of the crystalline silicon solar cell module, it will not scratch the crystalline silicon solar cell module and reduce the Disqualification caused by scratches on the frame.

A handle 7 is provided at the end of the edge protection 4 facing the tip of the included angle α, and the handle 7 is arranged on the intersection line of the two wings of the edge protection 4 to facilitate the use and portability of the device.

The included angle α in this embodiment is 90°.

The working principle of this device: When grinding, first stack the crystalline silicon solar cell components that need to be polished, connect the motor 1 to the power supply, and then grasp the handle 7 to attach the edge protection 4 to the corner edge of the crystalline silicon solar cell components.
