Component splicing


3。1 Preparation:

Check the work surface and do not allow debris (including solder, interconnecting strips, bus bars, hair, dirt, etc。)。 All work uniforms and work caps must be neatly dressed before work。


3.2 Overview of the work:

The strings of the strings are spliced together and the laminates are laid in the prescribed order。


3.3 Welding:

Place the battery strips on the back side of the strip and place them one by one on the tempered glass. When the series strips are placed, they have a certain directionality. They must be visited according to the arrangement specified on the drawings and adjust the front, rear, left and right spacing. Then, the positioning strips are used to fix the series strips; then the bus bars are used to complete the assembly and soldering of the battery tandem strips; Positive, negative and tap lead strips.

Prepare the component glass。 If it is suede, lay the surface of the hair on the surface, lay a layer of surface EVA film (the matte side up), and then slide the just assembled battery in series to the surface EVA film。 Then lay a layer of back EVA film (matte face down)。 Finally, the back film (reverse side down) is laid on the uppermost surface, and the outlet hole corresponds to the position of the lead wire (the EVA also corresponds to the position opening hole), and then the lead wire protrudes from the outlet hole。

3.4 Quality requirements:

1 Check the battery for cracks and defects, and replace if necessary。

2 Whether the gap between the battery serial strips is consistent, and no obvious deviation is allowed。

3 positive and negative leads to the civilian must be correct.

4 Check the surface of each layer inside the component, and prohibit all kinds of debris from entering the component.

5 Whether the laminate is laid in accordance with the process card.


3。5 Notes:

1 During the laying process, always pay attention to the symmetry of the position of each layer.

2 When the bus bar is welded, always use the uniform tool to press the bus bar at the welding place.

3 Keep the entire work bar clean.
