Description

Technical Field

[0001] The present application relates to the field of solar cell processing technology, and in particular to a temperature-adjustable cutting platform. 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] In the existing non-destructive cutting technology, the cutting platform is not heated, and the battery cells are placed on the platform for cutting without preheating, so the temperature rises slowly. In order to quickly reach the expected temperature during the cutting process, the thermal cracking laser power must be increased. If the thermal cracking laser power is too high, it will cause cutting quality problems such as hidden cracks and missing corners. In addition, the cutting process is accompanied by water mist spraying, and there will be water stains on the cutting platform. The water stains will adhere to the battery cells, making it difficult to cut the battery cells or there will be missing corners after cutting, which will also cause cutting quality problems.

In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0021] The following is combined with Figure 1-3 This application is described in further detail.

[0022] The embodiment of the present application discloses a temperature-adjustable cutting platform.

[0023] Reference Figure 1 A temperature-adjustable cutting platform includes a main body 1 and a temperature controller. The main body 1 is provided with one or more groups of heaters 2. Each group of heaters 2 includes two heating rods 3. The two heating rods 3 are symmetrical with the central axis 4 of the main body 1 as the symmetry axis. The heating rods 3 are connected to the temperature controller.

[0024] Before cutting the solar cell, it is necessary to fix the solar cell to the cutting platform body 1, and use the thermostat to control the heating rod 2 to heat the body 1, and transfer heat to the solar cell through the body 1, so that the solar cell is heated to the set temperature, and the temperature is adjustable. In the actual cutting process, it is necessary to use the thermostat to control the heating rod 2 to preheat the cutting platform body 1, so that when the solar cell is fixed to the cutting platform, it can quickly heat up and reach the set cutting temperature, which helps to prevent cutting quality problems caused by excessive thermal cracking laser power. At the same time, the cutting platform heats and quickly evaporates the residual water stains during the cutting process, which helps to prevent cutting quality problems caused by water stains adhering to the solar cell.

[0025] By arranging the two heating rods 3 in the heater 2 symmetrically, both ends of the body 1 can be heated simultaneously, so that the temperature of the body 1 is approximately equal, thereby maintaining the same surface temperature of the solar cell.

[0026] In this embodiment, the heating rod 3 is cylindrical, and its heating temperature is controlled by a thermostat, which adjusts the heating process of the heating rod 3 according to the actual temperature and the set temperature, so that the platform is always kept at the set temperature value. In actual use, the arrangement position and number of the heating rods 3 can be adjusted according to actual working conditions.

[0027] In one embodiment, the main body 1 is provided with a plurality of heating holes 5, the length direction of the heating holes 5 is the same as the direction of the central axis 4 of the main body 1, the heating holes 5 pass through the main body 1, the heating rod 3 is arranged in the heating hole 5, and one end of the heating rod 3 extends out of the heating hole 5.

[0028] In this embodiment, the heating rod 3 is fixed in the heating hole 5 by a snap-fitting manner. When the heating rod 3 needs to be repaired or replaced, the heater 2 can be directly removed through the end of the heating rod 3 extending outside the heating hole 5, or the heating rod 3 can be pushed out of the heating hole 5 at the other end of the heating hole 5, which is convenient for disassembly and assembly and easy to operate.

[0029] In one embodiment, the main body 1 is provided with one or more groups of adsorption holes 6, each group of adsorption holes 6 includes two groups of vacuum holes 7, each group of vacuum holes 7 includes multiple vacuum holes 7, the multiple vacuum holes 7 are distributed along the central axis 4 of the main body 1, and the two groups of vacuum holes 7 are symmetrical along the central axis 4 of the main body 1.

[0030] Before cutting the solar cell, the solar cell is adsorbed on the surface of the body 1 by the adsorption holes 6, thereby fixing the position of the solar cell to prevent the solar cell from shifting during cutting. After the cutting is completed, the divided solar cells are adsorbed by the two groups of vacuum holes 7 respectively, so that the solar cell is stably transported out of the cutting machine.

[0031] In one embodiment, the body 1 is provided with a plurality of vacuum channels 8 , each vacuum channel 8 corresponds to a group of vacuum holes 7 , each vacuum hole 7 in each group of vacuum holes 7 is connected to a vacuum channel 8 , and the vacuum channel 8 is provided with a vacuum joint 9 .

[0032] The vacuum joint 9 is used to be connected with an external machine, and the vacuum channel 8 is placed in a negative pressure state by the external machine, thereby placing the vacuum hole 7 in a negative pressure state, so as to adsorb the solar cell to the body 1 .

[0033] In one embodiment, a plurality of mounting holes 10 are provided on the peripheral wall of the body 1 , and a temperature measuring device 11 is provided in the mounting hole 10 , and the temperature measuring device 11 is connected to the temperature controller.

[0034] The temperature is measured by the temperature measuring device 11 and sent to the thermostat. The thermostat adjusts the heater 2 to heat according to the actual temperature so that the body 1 is within the set temperature range, thereby heating the solar cell to the set temperature, which is convenient for cutting the solar cell.

[0035] In one embodiment, the temperature measuring device 11 comprises a thermocouple.

[0036] 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.
