Abstract
The invention discloses a production method of a photovoltaic cell junction box, comprising the following steps of: manufacturing an integral metal conducting sheet according to designed shape; dividing the metal conducting sheet into a plurality of areas; physically connecting the areas into a whole; welding a diode onto the metal conducting sheet; putting the metal conducting sheet welded with the diode into the box of a wiring box; arranging a through hole on the box body corresponding to the junction of the metal conducting sheet; and causing a tool to extend into a through hole to cut off the metal conducting sheet to cause the metal conducting sheet into a plurality of mutually independent sheets. The production technology is optimized with the method.
Description
Technical field
The present invention relates to a kind of production method of photovoltaic cell junction box.
Background technology
In the production process of photovoltaic cell junction box, the welding of diode, detection are most important, also are the operations of difficulty maximum.
Summary of the invention
The production method of photovoltaic cell junction box comprises the steps: to make whole metallic conduction sheet according to the shape of design, and this metallic conduction sheet is divided into several zones at profile, but is that connection is as a whole physically; Welding diode to the metallic conduction sheet, is made between the sheet metal in adjacent two zones to link to each other with diode; With pack into the box body of terminal box of the metallic conduction sheet that welds diode, this box body has through hole in the connecting portion office corresponding to the metallic conduction sheet; Instrument stretches in the through hole metallic conduction sheet is cut off, and makes it become physically mutually independently some.
Method of the present invention was just carried out the welding of diode before plastic box body that the metallic conduction sheet is packed into, because the metallic conduction sheet is smooth thin slice generally, so be suitable for operating with automatic welding equipment, guaranteed welding quality, had improved welding efficiency.On the other hand, the present invention will be referred to be placed on front road than the operation that high-tech requires, and later process is relatively simple, so just might take the production method of strange land packing, namely after head factory is finished the welding of diode and metallic conduction sheet, transport to assembling and the conducting strip that subsidiary factory carries out plastic casing and thrust, so more be conducive to organization of production and quality management.As seen, method of the present invention has been optimized production technology.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described in more detail.
Fig. 1 is the junction box structure schematic diagram that utilizes before the inventive method is produced.
Fig. 2 utilizes the inventive method that the metallic conduction sheet is installed in schematic diagram in the terminal box.
Fig. 3 is terminal box bottom schematic view after utilizing the inventive method to be installed in the metallic conduction sheet in the terminal box.
Embodiment
Referring to Fig. 1.Be divided into 4 zones at profile on the metallic conduction sheet 2, each zone connects by junction 7, and making it is an integral body physically.
Referring to Fig. 2.After being welded and fixed with diode 4 and for holistic metallic conduction sheet 2, the metallic conduction sheet 2 that has welded diode 4 is packed in the box body 1 of terminal box, on box body 1 bottom with projection 3, projection 3 stretches out from the installing hole 5 on the metallic conduction sheet 2, after tool using melted projection 3, metallic conduction sheet 2 just was fixed together with box body 1.
Referring to Fig. 3.The bottom of the box body 1 of terminal box has through hole 6, and behind the box body 1 of terminal box that metallic conduction sheet 2 is packed into, the junction 7 of metallic conduction sheet 2 just in time is positioned at through hole 6 places.Tool using stretches in the through hole 6, and after junction 7 cut-outs with metallic conduction sheet 2, metallic conduction sheet 2 just becomes mutually independently 4 metallic conduction sheets 2.
