Technical Field
[0001] The present application relates to the field of photovoltaic manufacturing equipment, and in particular to a nozzle for non-destructive cutting. Background Art
[0002] In the development of the solar cell industry, the large size of cells has become a trend, which can improve the conversion efficiency and power of the module to a certain extent. However, the increasing size of cells will lead to an increase in the working current of the cells, which will cause the working current of the module to increase, thereby increasing the safety risk of the module. Therefore, it has become a development trend in the industry to cut the cells into small pieces and then assemble them in series to reduce the working current and improve the reliability of the module. The market share of half-cell modules has increased rapidly. On the other hand, the shingled module technology relies on cutting the cells into small pieces and stacking them to connect them, eliminating the gap between the cells in the string, which can improve the utilization rate of the module area and improve the power and conversion efficiency of the module.
[0003] Whether it is a half-cell module or a shingled module technology, the solar cell needs to be cut. In the process of cutting the cell using dual laser thermal cracking, a nozzle needs to be used for water spray cooling. When the existing nozzle sprays water mist, the angle of the water mist cannot be adjusted due to the fixed structure of the nozzle. Therefore, according to different process requirements, the nozzle needs to be replaced to adjust the water mist angle. In this way, the nozzle needs to be replaced many times during the cutting process, which causes inconvenience to the cutting work to a certain extent and also reduces the cutting efficiency. Utility Model Content
[0004] In order to improve the problem of inconvenience and reduced cutting efficiency caused by replacing the nozzle during the cutting process, the present application provides a nozzle for non-destructive cutting.
[0005] The present application provides a non-destructive cutting nozzle using the following technical solution:
[0006] A nozzle for non-destructive cutting comprises: a mounting block and an adjusting column, wherein the mounting block is provided with a threaded column, the threaded column is threadedly connected to the inner wall of the adjusting column, the threaded column is provided with a water outlet column, the water outlet column is arranged in the adjusting column, a water outlet channel is arranged in the water outlet column, an air outlet channel is formed between the outer wall of the water outlet column and the inner wall of the adjusting column, the mounting block is provided with a water inlet and an air inlet, the water inlet is communicated with the water outlet channel, the air inlet is communicated with the air outlet channel, the adjusting column is provided with a water outlet, and the adjusting column is also provided with an adjusting component for adjusting the relative position of the water outlet column and the water outlet.
[0007] In one embodiment, the adjustment assembly includes an adjustment nut, the adjustment nut is fixed to the adjustment column, and the adjustment nut is threadedly connected to the threaded column.
[0008] In one embodiment, the water outlet column includes a water delivery column and a water outlet hole, the water outlet channel is located in the water delivery column, the water outlet hole is provided with a mounting column, and the mounting column is threadedly connected to the water outlet column.
[0009] In one embodiment, opposite side walls of the mounting block are each provided with a plurality of mounting holes.
[0010] The non-destructive cutting nozzle provided in the embodiment of the present disclosure can achieve the following technical effects:
[0011] In the initial position, the water outlet of the water column is flush with the water outlet, and high-pressure gas is ejected from the gap between the water outlet of the water column and the water outlet, breaking up the water into water mist and forming a certain spray angle. At this time, according to the process requirements, if the spray angle needs to be increased, the adjustment component is used to adjust the water column to retract into the adjustment column; if the spray angle needs to be reduced, the adjustment component is used to extend the water column outside the adjustment column. In this way, the relative position of the water column and the water outlet is changed by the adjustment component, thereby changing the spray angle, so that the scope of application of the nozzle is expanded, so that in the process of cutting solar cells, the spray angle can be adjusted according to different processes, which improves convenience, avoids multiple nozzle changes, and improves cutting efficiency.

[0019] The following is combined with Figure 1-3 This application is described in further detail.
[0020] The embodiment of the present application discloses a nozzle for non-destructive cutting.
[0021] A nozzle for non-destructive cutting comprises a mounting block 1 and an adjusting column 2, wherein the mounting block 1 is provided with a threaded column 3, the threaded column 3 is threadedly connected to the inner wall of the adjusting column 2, the threaded column 3 is provided with a water outlet column 4, the water outlet column 4 is arranged in the adjusting column 2, a water outlet channel 5 is arranged in the water outlet column 4, an air outlet channel 6 is formed between the outer wall of the water outlet column 4 and the inner wall of the adjusting column 2, the mounting block 1 is provided with a water inlet 7 and an air inlet 8, the water inlet 7 is connected to the water outlet channel 5, the air inlet 8 is connected to the air outlet channel 6, the adjusting column 2 is provided with a water outlet, and the adjusting column 2 is also provided with an adjusting component 9 for adjusting the relative position of the water outlet column 4 and the water outlet.
[0022] During use, water enters the water column 4 through the water inlet 7 and is sprayed out, and the high-pressure gas enters the air outlet channel 6 through the air inlet 8, and then breaks up the water to form water mist. In the initial position, the water outlet of the water column 4 is flush with the water outlet, and the high-pressure gas is sprayed from the gap between the water outlet of the water column 4 and the water outlet, breaking up the water into water mist and forming a certain spray angle. At this time, according to the process requirements, if the spray angle needs to be increased, the adjustment component 9 is used to adjust the water column 4 to retract into the adjustment column 2; if the spray angle needs to be reduced, the adjustment component 9 is used to extend the water column 4 out of the adjustment column 2.
[0023] In this way, the relative position of the water column 4 and the water outlet is changed by adjusting the component 9, thereby changing the spray angle, so that the application range of the nozzle is expanded. In the process of cutting solar cells, the spray angle can be adjusted according to different processes, which improves convenience, avoids multiple nozzle changes, and improves cutting efficiency.
[0024] In one embodiment, the adjustment assembly 9 includes an adjustment nut 91 , which is fixed to the adjustment column 2 , and the adjustment nut 91 is threadedly connected to the threaded column 3 .
[0025] By rotating the adjusting nut 91, the adjusting column 2 is rotated. At this time, since the adjusting column 2 is threadedly connected to the threaded column 3, the adjusting column 2 and the threaded column 3 move relative to each other, thereby adjusting the relative position of the water outlet column 4 and the water outlet, which is easy to operate.
[0026] In one embodiment, the water outlet column 4 includes a water delivery column 41 and a water outlet hole 42 . The water outlet channel 5 is located in the water delivery column 41 . The water outlet hole 42 is provided with a mounting column 10 . The mounting column 10 is threadedly connected to the water outlet column 4 .
[0027] In this way, the diameter of the water outlet hole 42 can be changed according to the working conditions, thereby changing the water output of the nozzle and improving the applicable range of the nozzle.

[0029] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
