What is the impact of the LR03 alkaline battery production process on the performance of the component?
The rise of solar energy has brought a lot of convenience to our lives, and it is more popular due to its energy-saving and pollution-free characteristics. However, in the production process of solar modules, various problems are often encountered. The emergence of these problems will have various effects on the performance of solar modules. The following simple analysis summarizes the analysis of common problems in module production.
a. Causes of network cracks
1. The cell is caused by external forces during welding or handling.
2. The cell is not preheated at low temperature and suddenly expands for a short period of time at high temperature.
Impact on components:
1. Grid cracks will affect the power attenuation of components.
2. Long network cracking time, hot spots, etc. directly affect the performance of components
Preventive measures:
1. Avoid excessive collision of batteries during production.
2. During welding, the battery should be pre-insulated (manual welding) and the soldering iron temperature should meet the requirements
3. EL test must be strictly required for testing.
b. Causes of EVA delamination
1. The degree of cross-linking is unqualified. (Such as low laminating machine temperature, short laminating time, etc.)
2. The surface of raw materials such as EVA, glass, and bottom plate is caused by foreign matter.
3. The composition of EVA raw materials is uneven (such as ethylene and vinyl acetate), which cannot be dissolved at room temperature, resulting in stratification.
As shown in 4. When the outside world encounters high temperature for a long time, a large amount of magnetic flux and stratification of the main gate line will be generated.
Impact on components:
1. When the stratification area is small, it will affect the high power consumption of the components. When the stratification area is large, the components fail and are scrapped.
Preventive measures:
1. Strictly control the laminating machine of important parameters such as temperature and time, and regularly conduct cross-linking tests according to demand, and control the cross-linking degree at 85% ± 5%.
2. Strengthen the improvement of raw material suppliers and the inspection of raw materials
3. Strengthen the appearance inspection of finished products during the production process
As shown in 4. Strictly control the flow rate, try not to exceed about 0.3 mm of the main grid
c. Causes of battery splitting
1. Improper operation during welding will cause fragments
2. When the lifting method is incorrect, improper placement of personnel will cause component fragments
Laminator failure occurs in the component class
Impact on components:
1. Partial failure of the leaf petal affects the power attenuation of the component.
The power attenuation or complete failure of the microcontroller battery affects the power attenuation of the component
Preventive measures:
1. The busbar welding and rework areas are strictly operated in accordance with the sop method.
2. When lifting and unloading components, personnel should strictly follow the process requirements to lift and unload components.
3. Ensure regular maintenance of the laminating machine. Every replacement of the equipment must be carried out after the first confirmation in production
4. EL detection is strictly checked and inspected, and bad leakage is strictly prohibited
d. Causes of foam generation
1. The vacuum temperature of the laminate is too short, and bubbles will appear when the temperature is too low or too high.
2. If it is not clean inside, there will be foreign matter and bubbles will appear
3. If the size of the upper insulating tape is too large or too small, it will cause bubbles
Impact on components:
Bubbles in components will affect the delamination, and in severe cases will lead to scrapping
Preventive measures:
1. The vacuum time and temperature parameters of the laminator should be set strictly in accordance with the process requirements
2. During welding and lamination, attention should be paid to the 5s cleaning of the process
3. The cutting size of the insulating tape is strictly required to be cut and checked
