High-precision connection point punching and breaking device

Abstract

The invention discloses a high-precision connection point punching and breaking device. The device comprises a base, wherein a frame is arranged at one side of the surface of the base; an air cylinder is arranged on the frame, is vertically arranged downward and is connected with a guide plate; an upper die base is arranged at the bottom of the guide plate; punches are arranged at the bottom of the upper die base; the surfaces of the punches are sleeved by an upper die sleeve; guide pillars are arranged on the upper die sleeve, penetrate through the upper die base and are arranged in the guide plate; limiting slots are formed in the guide plate; limiting bulges are arranged at the tops of the guide pillars; the limiting slots are matched with the limiting bulges for limiting; the guide pillars between the upper die base and the upper die sleeve are also sleeved by pressure springs; locating guide sleeves matched with the punches are arranged at the bottom of the upper die sleeve; locating pins are also arranged at one sides of the locating guide sleeves; and a lower die core matched with the punches for stamping is arranged on a base below the punches and is arranged on a lower die platform. The device has a simple structure, good punching and breaking effects and high punching and breaking efficiency and has the effect of effectively saving the labor cost.

Description

technical field [0001] The invention relates to the field of photovoltaics, in particular to a high-precision connection point breaking device. Background technique [0002] The photovoltaic junction box is a connector between the solar cell array formed by solar cell modules and the solar charge control device. It needs to place the conductive sheet in the box body, and the conductive sheet is a whole that is punched into a row at one time and is composed of multiple pieces that are connected to each other. The existing assembly method is manually broken and put in one by one. The sheet is bent, and the fracture has burrs, etc., which affects the product quality and greatly reduces the operating efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the above problems existing in the prior art, and provide a high-precision connection point punching device. The invention has simple structure, good punching effect, high punching ...
