An automatic needle pressing machine for assembling the grounding pole core needle of a triangular plug

Abstract

The invention discloses an automatic needle pressing machine used for triangle plug grounding electrode core needle assembling. The machine comprises a needle sending mechanism, a needle falling mechanism, a needle pushing mechanism, a needle pressing mechanism, a needle sending guide rail and a central controller. The needle sending mechanism and the needle falling mechanism are connected through the needle sending guide rail. The needle pushing mechanism moves back and forth on a working position of the needle falling mechanism and a working position of the needle pressing mechanism. The central controller is connected to the needle sending mechanism, the needle falling mechanism, the needle pushing mechanism and the needle pressing mechanism in a signal connection mode. In the invention, a ''fission manufacturing + pressure assembling'' design scheme is adopted; a harbor-type triangle plug is formed through injection molding separately; a core needle assembling hole is reserved on a grounding electrode; and a core needle separately adopts a wire rod and is formed through direct clipping. During assembling, the triangle plug is fixed; through applying certain pressure to the core needle, a grounding electrode assembling hole is aligned and is vertically pressed into the assembling hole; an assembling technology is simple and assembling is reliable; manual secondary tail cutting, glue sealing and other operations are not needed and a next step of automation operation can be directly entered into.

Description

technical field [0001] The invention relates to the technical field of plug grounding pole core needle processing, in particular to an automatic needle press machine for assembling a triangular plug ground pole core pin. Background technique [0002] Among the European triangular plugs, according to different usage requirements, there is a triangular plug with a grounding pole (E pole) angle plug designed as an insulated end. The material of the grounding pole is generally ABS, PC and other plastics. Due to the problem that the plastic material has a certain shrinkage rate and the strength of the material itself is much lower than that of metal, the simple plastic grounding electrode will easily break during use due to insufficient mechanical indicators such as strength, making the plug unable to reach to the design life requirements. Therefore, in the actual design of the plug, in order to improve the overall strength of the plug, a reinforcing needle is usually embedded i...

Problems solved by technology

Affected by the process itself, during the actual application of the in-mold injection molding assembly scheme, a part of the needle tail of the core needle will always remain outside the body of the ground electrode, and it is necessary to manually cut the needle tail and seal the glue twice, making the entire assembly process more complicated. Complex, high labor cost

At the same time, the mold structure of the in-mold injection molding technology is complex, the manufacturing cost is high, and the actual assembly effect has a certain gap with the expectation
