Embodiment Construction

[0026] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Such as figure 1 As shown, there is a uniform adhesive layer 2 between the solar cell 3 and the surface protection layer 1 . The thickness of protective layer 1 is: 0.12 -0.02 +0.04 mm, the overall dimension is: 40.20±0.10×20.10±0.10mm The thickness of the solar cell is: 0.20 -0.01 +0.04 mm. The thickness of the adhesive layer 2 is required to be less than 0.1 mm. In order to meet the thickness requirement of the adhesive layer 2, the present invention utilizes the viscosity and fluidity of the colloid to spread the adhesive layer 2 evenly on the surface of the solar cell 3 before the protective layer 1 is packaged. The specific method is as follows:

[0028] At room temperature (15-25°C), measure the external dimensions of the solar cell 3 as m=40.25±0.05, n=20.20±0.05. According to the required thickness of the...

Abstract

In the continuous glue-dropping process for packing solar cell with glue layer in controllable thickness, the glue-dropping path for robot is programmed in computer for some solar cell with certain shape and sizes to determine the distance between two lines of path and the edge distance of cell; and the path file is then downloaded into the controller of three-free dimension rectangular coordinate robot white selecting proper glue-dropping syringe and controlling glue-dropping pressure to different parameter range and glue thickness to complete the glue-dropping process. Via regulating relevant parameters, the present invention can control the glue thickness precisely, control the overflow of glue and avoid the contamination of glue to the cell.

Description

Technical field: [0001] The invention relates to a continuous glue dispensing method with controllable thickness of the solar cell packaging adhesive layer, which adopts digital automatic glue application technology to realize the thickness control of the adhesive layer of the solar cell surface protective layer packaging, and belongs to IC post-packaging [0002] technology field. Background technique: [0003] At present, with the development of solar cell manufacturing process, the dispensing method of solar cell encapsulation has become one of the key factors affecting the encapsulation quality. In order to protect the solar cells used in the space environment, it is necessary to carry out the encapsulation operation of the protective layer and the device. In the past, most of the device protection layer packaging processes were manually operated. This method not only has low precision and high labor intensity, but also has low yield and low efficiency. It is mainly re...
