Description

Technical Field

[0001] The utility model belongs to the field of solar cell processing, and in particular relates to an arc and straight line integrated busbar cutting mechanism. Background Art

[0002] Crystalline solar panels are devices that use the photovoltaic effect to convert solar energy into electrical energy. Crystalline solar panels, also known as photovoltaic solar panels, are usually composed of multiple photovoltaic cells that absorb sunlight and convert it into direct current electricity. These panels can be installed on the roof of a building, on the ground or other appropriate areas for power generation or supply. Photovoltaic solar panels, as an important means of clean energy generation, are increasingly valued and widely used.

[0003] During the production of crystalline solar cells, busbars are usually laid on photovoltaic solar panels. When the busbars are cut, they are usually divided into two types according to their different conditions. One is as shown in the attached Figure 1 The regular shape shown in a is a straight line with four right angles. The other is as shown in the attached Figure 1 The shape of the installation of the junction box in the process shown in b is an arc shape, that is, the four corners are arcs. The existing cutting mechanism is usually a straight knife or an arc knife, and the straight knife cuts a busbar in shape a, which has sharp corners and affects the installation of the junction box in the subsequent process, while the arc knife cuts a busbar in shape b that can meet the needs of the subsequent process, but the place where the junction box does not need to be installed is also an arc, which does not meet the requirements and will cause waste of materials. That is, the busbar cutting mechanism currently in the field of solar cell processing cannot meet the requirements of being able to cut busbars in shapes a and b at the same time, and requires frequent shutdowns to replace the tool module to meet the requirements, which affects the cutting efficiency. In view of this, the utility model provides an arc and straight line integrated busbar cutting mechanism. Utility Model Content

[0004] In order to solve the above problems, the utility model provides an arc-straight-line integrated busbar cutting mechanism, which can cut busbars in both straight and arc shapes without stopping the machine, which can meet the cutting needs of conventional busbars and the needs of busbars installed using process junction boxes, thereby realizing the integrated cutting of linear and arc-shaped busbars and improving the cutting and processing efficiency.

[0005] The utility model is realized by the following technical solutions:

[0006] Arc-linear integrated busbar cutting mechanism, including a cutting cylinder, a cutting module and a die-changing cylinder. The cutting module includes an upper die and a lower die. The movable end of the cutting cylinder is connected to the upper die. The die-changing cylinder is arranged on the side of the lower die. The lower die includes a base and a die-changing component. The die-changing component is movably connected to the base, and the die-changing component is connected to the movable end of the die-changing cylinder.

[0007] As a preferred technical solution, it further includes a cutting bracket. The cutting cylinder is fixed to the top of the cutting bracket. The upper die is arranged inside the cutting bracket. The lower die is fixed to the bottom surface of the cutting bracket. The die-changing cylinder is fixed to the side of the cutting bracket.

[0008] As a preferred technical solution, the cutting bracket is composed of a top plate, a bottom plate, a left side plate and a right side plate.

[0009] As a preferred technical solution, the lower die is fixed to the bottom plate by bolts.

[0010] As a preferred technical solution, it further includes a sliding seat. The sliding seat is provided with a slide rail and a moving cylinder. The bottom of the cutting bracket is slidably connected to the slide rail. The movable end of the moving cylinder is fixedly connected to the side of the cutting bracket.

[0011] Beneficial effects:

[0012] By setting the structure of the cutting cylinder, the cutting module and the die-changing cylinder, the cutting module is composed of an upper die and a lower die. The upper die is connected to the movable end of the cutting cylinder. The movement of the upper die is controlled by the cutting cylinder to cooperate with the lower die for cutting. The lower die is composed of a base and a die-changing component. The die-changing component is movably connected to the base and is connected to the movable end of the die-changing cylinder. When in the initial position, the cutting cylinder can control the up and down movement of the upper die to cut a linear busbar with the lower die. When it is necessary to cut into an arc shape, the die-changing cylinder drives the die-changing component to reach the die-changing position. Then, when the cutting cylinder pushes the upper die to move up and down, it can cooperate with the lower die to cut an arc-shaped busbar. Through the above structure, the utility model can cut two shapes of busbars, linear and arc-shaped, without stopping the machine, which not only meets the cutting needs of conventional busbars but also meets the needs of busbars for the installation of wiring boxes in the use process, realizing the integration of linear and arc-shaped busbar cutting and improving the cutting and processing efficiency.
