Automatic Junction Box Production Line
Produces solar panel junction boxes on an eight-station rotary table. The line combines hot-press plastic riveting, diode cutting and placement from a strip, MFDC welding, two solder pool operations, inspection and/or marking, and automatic unloading. The first station supports operator loading or optional automatic feeding.
Configurations vary by model and application.

TYPICAL APPLICATIONS
Eight-station production process
The preassembled plastic housing and metal components are loaded into the fixture. Operator loading or optional automatic feeding is available.
The plastic part is automatically riveted with a hot press.
The strip-fed diode is automatically cut and placed on the product.
Both diode leads are welded in a piano-style sequence at a twin-piston station with an MFDC transformer.
Automatic solder wire feeding and a soldering machine fill the first pool with molten solder. A soldering iron cleaning station is included.
Automatic solder wire feeding and a soldering machine fill the second pool with molten solder. A soldering iron cleaning station is included.
The product undergoes inspection and/or marking.
The completed product is unloaded automatically.
