Junction box copper sheet punching machine for an assembly line

Abstract

A junction box copper sheet punching machine for an assembly line comprises a punching machine, an upper mold and a lower mold; the upper mold comprises an upper mold plate and an upper pressing block; the upper end of the upper mold plate is connected to a pressing head of the punching machine through connecting blocks; the upper mold plate is further provided with a plurality of heads; a corresponding number of head guiding holes are arranged on positions, corresponding to the heads, of the upper pressing block; the heads can slide up and down in the head guiding holes; the lower mold includes a lower pressing block, a lower mold plate, and a transverse cylinder; both ends of the lower pressing block are provided with left and right limiting blocks; the inner sides of the left and rightlimiting blocks is provided with guiding inclined surfaces; and the lower pressing block is provided with a plurality of punching holes; the lower mold plate is provided with blanking holes at the positions corresponding to the punching holes; and bottom ends of lower mold plate guiding columns are fixed on a bottom frame of the punching machine. The machine has compact structure and high processing efficiency.

Description

technical field [0001] The invention relates to a copper sheet punching machine for a junction box used in an assembly line. Background technique [0002] The photovoltaic junction box is an important part used to connect photovoltaic module panels and inverters in solar power generation systems. It needs a lot of use in the power grid, so the assembly line mass processing of junction boxes is the current trend of junction box production. [0003] In the mass assembly line production of junction boxes, an important process is the copper sheet punching process of junction boxes. The content of this process is to punch out a plurality of through holes on the junction box and the circuit board installed in the junction box, and the through holes can be used for subsequent component installation or self-dissipation of the junction box. [0004] Small punches and matching stamping dies must be used in the copper sheet punching process. However, due to the fast working speed and...

AI Technical Summary

Problems solved by technology

[0004] Small punches and matching stamping dies must be used in the copper sheet punching process. However, due to the fast working speed and small space of the assembly line, there are many problems in installing a junction box copper sheet punching machine on the assembly line.
