An electric vehicle controller pcb board copper bar punching device

Abstract

The invention discloses a PCB (Printed Circuit Board) copper bar leg punching device of an electric vehicle controller. The PCB copper bar leg punching device comprises a base, a leg punching component and a compressing mechanism, wherein the leg punching component comprises a lower backing plate, an upper backing plate and a plurality of leg punching insertion strips; the lower backing plate is arranged on the base; the leg punching insertion strips are fixedly arranged on the lower backing plate and correspond to copper bar leg holes in a controller PCB; the leg punching insertion strips are vertical to the lower backing plate; the lower backing plate is fixedly provided with a vertical rod; the upper backing plate is vertically and slidably arranged on the vertical rod; hollow holes used for exposing the leg punching insertion strips are formed in the upper backing plate; a compression spring used for applying an upward force to the upper backing plate is arranged between the upper backing plate and the lower backing plate; the compressing mechanism comprises a press plate arranged above the upper backing plate; the press plate is driven by a press plate power device. The leg punching device is simple in structure, convenient in operation, capable of rapidly performing leg punching on copper bars on the PCB, high in efficiency and good in quality.

Description

technical field [0001] The invention relates to a copper bar punching device, in particular to a copper bar punching device for an electric vehicle controller PCB board. Background technique [0002] The PCB board of the electric vehicle controller needs to install copper strips (or copper skins) on the parts with high current. There are several copper strip foot holes on the PCB board, and the copper strips need to be punched in the copper strip foot holes. , so that the pins on the copper strip are embedded in the foot holes of the copper strip, and then spot welding is performed to fix the copper strip. However, at present, there is no low-cost, simple-structured, relatively high-automated punching device in the punching process, but manual punching is required, which not only has low efficiency, but also poor molding quality. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a device for punching the copper st...
