Production method for shielding case

Abstract

The invention discloses a production method for a shielding case. The production method for the shielding case comprises the following steps: 1) primary stamping: forming the shielding case from raw materials through a continuous stamping die, and leaving the shielding case on a material belt formed at two ends of the raw material; 2) cleaning: arranging the raw materials of the shielding case onthe material belt, and cleaning the raw materials of the shielding case in a cleaning pool; 3) secondary stamping: arranging an automatic loading mechanism in another stamping die, automatically loading, carrying out secondary stamping on the shielding case in the stamping die, and completing further machining; and 4) cutting and packaging: cutting the shielding case on the material belt at a cutting station, separating the shielding case from the material belt, and feeding the product into a packaging machine for packaging after the product falls onto a conveyor belt. According to the production method for the shielding case, automatic loading for the shielding cases can be realized, so that the machining efficiency is increased, and scratching between the shielding cases during loading and conveying is avoided; and meanwhile the special material belt is arranged to avoid adhesion, oil contamination and scratching during cleaning. Great increasing for the yield is brought, and the yield is increased to 90% or above from original 80%.

Description

technical field [0001] The invention belongs to the technical field of shielding cover production, and in particular relates to a production method of a shielding cover. Background technique [0002] A shield is a tool used to shield electronic signals. The function is to shield the influence of external electromagnetic waves on the internal circuit and the external radiation of electromagnetic waves generated inside. Stainless steel and nickel nickel are mainly used as materials, of which nickel nickel is a metal shielding material that is easy to be tinned. [0003] The main function of the shielding cover is to block the electromagnetic wave in the cover, protect the internal electronic equipment from the harm of electromagnetic radiation, and avoid interference to other electrical appliances around it. life. There are two main functions of the shielding cover. The conscious shielding cover surrounds the interference source of components, circuits, assemblies, cables or...

AI Technical Summary

Problems solved by technology

[0008] 1. When the existing shielding covers are cleaned during the production process, each shielding cover is separated, and the collision and abrasion between each other are more serious

[0009] 2. When the existing shielding cover is cleaned during the production process, once the planes between the shielding covers overlap, they will stick together, because there is oil between the planes, the adhesion is difficult to separate, and the shielding cover will not be separated when the oil is cleaned. If the cleaning is not clean, adhesion and oil pollution will have a serious impact on the subsequent production and yield of the shielding cover
