Process Description:

Here only a brief look at the role of technology, give us an emotional understanding of the specific content of a further detail later:

1, The cell test: Because the randomness of the cell manufacturing conditions, the production out of cell performance is different, we will be for the effective performance of identical or similar battery together, it should be classified according to their performance parameters; cell test that is by testing the battery output parameters (current and voltage) of the size of its classification. To improve the utilization of the cells to make the components of acceptable quality.

2, Positive welding: It's convergence with soldered to the battery positive (negative) of the main gate line, convergence zone for the tinned copper strip, we use a welding machine can weld with a multi-point in the form of spot welding on the main gate Online. Welding heat source for an infrared lamp (using infrared thermal effect). Welding with the length of the side length of about 2 times the battery. More welding belt behind the back of welding with electrodes connected to the back of the battery piece. (Our company uses a manual welding)

3, On the back of concatenation: back of the weld is 36 cells cascaded together to form a component of the string, we are currently used process is manual, the battery depends mainly on the positioning of a membrane with plate 36 placed above the battery film grooves, groove size and battery size correspond to the location of tank has been designed well, different specifications of the components use a different template, the operator use electric soldering iron and solder wire will "in front of the battery," the positive electrode (cathode) Welding to the "behind the battery" on the back electrode (cathode), so that in turn will be 36 series with the component string together and welded out of positive and negative leads.

4, Laminated lay: on the back of a good tandem and tested after passing the component string, glass and cut a good EVA, glass fiber, backplane according to a certain level, laying a good preparation for lamination. Glass pre-coated layer of reagent (primer) in order to increase the bonding strength of glass and EVA. When installed to ensure the battery strings and glass and other materials relative position, adjusting the distance between the battery, in order to laminate lay a solid foundation. (Laying of levels: from the bottom up: glass, EVA, cell, EVA, glass fiber, backplane).

5, Component lamination: a good battery will be laid into the laminating machine, through the vacuum component of the air out, and then heated to melt the EVA batteries, glass and back bonding together; the final cooling out components. Lamination process is a key step in component production, lamination temperature lamination time, according to the nature of EVA. We use the fast-curing EVA, the lamination cycle time is about 25 minutes. Curing temperature of 150 ℃.

6, Trimming: laminated EVA melt when the pressure of reaching out after curing due to the formation of flash, so it should be removed laminated finish.

7, Fitted box: similar to the glass mounted to a frame; to the glass component mounted aluminum frame to increase the intensity of the component, further sealing the battery components, longer battery life. Borders and glass components of the gap filled with silicone resin. The border between the connection with the angle button.

8, The welding junction box: In the component lead at the back of a box welded to facilitate the battery and other equipment or connections between cells.

9, High-pressure test: high-pressure test is defined as components of the border and the electrode lead a certain voltage is applied between the test component of the pressure resistance and dielectric strength to ensure that components in harsh natural conditions (lightning, etc.) will not be damaged under the .

10, Component testing: the test objective is to calibrate the battery output power to test its output characteristics, determine the quality grade components.
