Embodiment Construction
[0024] The following clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0025] A rework operation method for a poorly cured junction box of potting glue, comprising the following steps:
[0026] Step 1: Align the ends of the two console tables and place them in parallel, leaving a certain gap between the two console tables, and lay a layer of PE protective film on the console table;
[0027] Step 2: Use a packaging bag to wrap the uncured part of the junction box on the photovoltaic module, and use a packaging rope to fasten the packaging bag to the junction box;
[0028] Step 3: Turn the photovoltaic modul...

The invention discloses a rework operation method for a junction box with an unfavorably-curved pouring sealant. The rework operation method comprises the following steps of wrapping a part, which isnot curved, of the junction box on a photovoltaic module with a package bag; placing the photovoltaic module on an operating table, and pouring the pouring sealant which it not curved into the packagebag; turning over the photovoltaic module so that the junction box is arranged upwards; coating a glue removal agent in an amount of 3-5g on the curved pouring sealant resided on the junction box, and cleaning a dissolved mixture with a small wooden shovel; and cleanly absorbing the mixture remained on the junction box and a leading-out line with absorption paper, and pouring the junction box again by manual. By the rework operation method, the unfavorably-curved pouring sealant can be rapidly cleaned, the curing firmness of secondary pouring is improved, the installation quality of the junction box is ensured, moreover, the photovoltaic module during the cleaning process of the pouring sealant is effectively prevented from being damaged, secondary damage is prevented, the secondary pouring cost of the photovoltaic module is reduced, and the processing qualified rate of the photovoltaic module is improved.
Description
technical field [0001] The invention belongs to the field of photovoltaic module manufacturing, and specifically relates to a glue potting process for a junction box, and more specifically, a rework operation method for a junction box with poorly cured potting glue. Background technique [0002] Photovoltaic modules (also called solar panels) are the core part of the solar power generation system and the most important part of the solar power generation system. [0003] The main function of the junction box of the photovoltaic module is to connect and protect the solar photovoltaic module, and at the same time conduct the current generated by the photovoltaic module for the user. A general junction box is composed of a box cover, a box body, terminals, diodes, connecting wires, and connectors. [0004] The junction box is usually adhered to the backplane by potting glue. During the pasting process of the potting glue of the junction box, there are often products with poor c...
