Embodiment 1

[0030] 1) Select the main components produced by Dongguan Liduo Electronic Materials Co., Ltd. as glue A of epoxy resin and glue B as a curing agent; take by weight at 2:1, at an ambient temperature of 25°C and an ambient temperature of 60%. Under the condition of humidity, use a mixer to fully stir until it is completely transparent visually and the viscosity is 25 seconds, that is, the ready-to-use mixed glue is obtained. At the same time, fix the silicon crystal plate on a special glass tray, fix it with screws, put it in an oven and heat it to 80°C for 10 minutes;

[0031] 2) After baking, take out the silicon crystal plate together with the tray and place it on the workbench, and use a glue pot to drip glue, and the coating amount is 850g / m 2 ;

[0032] 3) Use a glass rod to make the mixed glue on the silicon crystal plate even;

[0033] 4) Put the glued silicon crystal plate together with the tray into the vacuum box smoothly, and vacuumize to -1×10 5 Pa and maintain ...

Embodiment 2

[0037] 1) Select glue A with epoxy resin as the main component and glue B as curing agent produced by Dongguan Liduo Electronic Materials Co., Ltd., and weigh them at a weight ratio of 2:1. Under humidity conditions, use a mixer to fully stir until it is completely transparent visually, and the viscosity is 28 seconds, that is, the ready-to-use mixed glue is obtained. At the same time, fix the silicon crystal plate on a special glass tray, fix it with screws, and bake it in an oven at 80°C for 10 minutes;

[0038] 2) Take out the baked silicon crystal plate together with the tray and place it on the workbench, inject glue with a syringe, and the coating amount is 920g / m 2 ;

[0039] 3) Use a glass rod to make the mixed glue on the silicon crystal plate even;

[0040] 4) Put the glued silicon crystal plate together with the tray into the vacuum box smoothly, and vacuumize to -1×10 5 Pa and maintain for 5 minutes;

[0041] 5) Take out the silicon crystal plate together with ...

Abstract

The present invention discloses a dripping adhesive encapsulation method of a solar paster component, the steps are: A, placing the solar paster plate in the bake oven for baking; B, the mix gum is stirred to colloid transparent by stirring implement after the A gum and the B gum are mixed by volume ratio; C, the homogeneous mix gum is injected into dripping gum tools to inject mix gum on the front face of the paster; D, the mix gum on the paster plate is uniform by the glass rod; E, the dripping rubber plate is arranged in the vacuum box to start-up the vacuum switch; F, the dripping slab rubber with a vacuum treating is placed in the bake oven to solid the dripping slab rubber in the bake oven; G, the dripping slab rubber is taken out from the bake oven, and the redundant gum is removed at the temperature below 50EDG C. The method of present invention is good, the produced dripping rubber plate has high light transmittance ratio, good sealability, beautiful external shape, long length of life, reasonable process design, easy operations, short curing time, tight combination between the colloid and the silicon plate.

Description

technical field [0001] The invention belongs to the technical field of semi-finished product processing of solar photovoltaic cell components, and more specifically relates to a method for encapsulating solar patch components with glue, and is especially suitable for the processing of semi-finished solar photovoltaic cell components. Background technique [0002] Solar cell modules refer to solar photovoltaic devices composed of solar cells, packaging materials, junction boxes, etc. Solar patch components refer to silicon crystal panel components made by welding silicon-based solar cells to epoxy resin plates or plastic plates through the patch process. There are no welding spots on the surface, and the gaps between the solar battery sheets are small and uniform, which can improve the photoelectric conversion rate of the solar battery module. The silicon crystal plate can be a single crystal silicon plate or a polycrystalline silicon plate. [0003] At present, there are t...
