Existing Problems First, there are fragments in the component 1. Because there is no welding leveling in the whole process of electric welding, there is a pile of tin or tin slag, and the battery is damaged in vacuum packaging. 2. The original battery has already been damaged, and then the lamination is too early. EVA also has excellent fluidity. 3. In the case of lifting the component, the hand type is not scientific, and both hands have pressed the battery piece. Two, there is a bubble in the component 1. EVA has been cut and put for a long time. It has been damp. 2. EVA raw material itself is impure. 3, vacuum packaging is too short, charging can not drive out the bubble. 4. The working pressure of lamination is insufficient. 5, the temperature of the heating plate is not uniform, so that part of the early dry solid. 6, the lamination time is too long or the temperature is too high, so that the organic chemical chloroprene is dissolved, and the output rate is co2. 7. There are dirty things, and the wet Angle is more than 90°, so that there is vapor on the side of the dirty things. Third, there is hair and waste in the component 1, because EVA, DNP, the car has electrostatic induction existence, the floating empty hair, dust and some small garbage suction to the surface. 2. When folded, the body works on the components without ensuring that the body is free of hair and waste. 3, some small bugs cruel to drill into the component. 4. The bus bar bends inward 1. In the lamination, more vapor will be gathered at the bus bar. The rubber plate presses down, presses the vapor out of the assembly, and that part of the gap needs to be filled by EVA, which has better fluidity. This kind of mobility of EVA bends the originally straight bus bar. 2. Wrap up EVA. Five, component back membrane convex concave uneven 1. Unnecessary EVA will stick to the high temperature cloth and rubber plate.
