Device for selective wave soldering of electric energy meter module and use method thereof

Abstract

The invention discloses a device for selective wave soldering of an electric energy meter module and a use method thereof. The device comprises a jig and a die. The jig comprises a bottom plate and acover plate. The cover plate is disposed on the bottom plate in a covered manner, and the bottom plate is fixedly connected with the cover plate through buckles on the two sides of the bottom plate. Aplurality of positioning frames, spraying holes, grooves and patches are arranged on the bottom plate. A plurality of spring components are detachably arranged on the cover plate. The die is providedwith a plurality of hollow columnar nozzles corresponding to the positions of the spraying holes, and the height of the nozzles is 10-50 mm. The die is provided with a temperature sensor. The die isfixedly disposed in the tin furnace, and the jig is disposed on the die. By arranging the positioning frame, the groove and the patch on the jig bottom plate, the components are protected, and the components are prevented from being damaged when wave crest passes; at the same time, the spring columns on the cover plate is used to press the components, so that the components are prevented from floating due to being washed up by the wave crests when the wave crests pass; and in addition, a temperature monitoring and alarming device is arranged on the die, so that operators can maintain the equipment in time and the normal operation of the equipment is guaranteed.

Description

technical field [0001] The invention relates to the technical field of electronic module welding processing, in particular to a device for selective wave soldering of electric energy meter modules and a method for using the same. Background technique [0002] Selective wave soldering, also known as selective soldering, is used in the field of through-hole soldering of PCB plug-ins. Due to different welding advantages, in the field of PCB through-hole soldering in recent years, it has gradually become a popular trend of through-hole soldering. The scope of application is not limited to: military industry Electronics, aerospace ship electronics, automotive electronics, digital cameras, printers, etc. have high welding requirements and complex multi-layer PCB through-hole welding. Selective wave soldering is divided into two types: offline selective wave soldering and online selective wave soldering. Body type 1+1, in which the preheating module follows the welding part, manua...

AI Technical Summary

Problems solved by technology

[0003] At present, the degree of automation in the field of electronic module processing is getting higher and higher. In the case of large-scale order operations, the welding function of ordinary wave soldering equipment commonly used now is aimed at single-sided over-wave PCB boards and double-sided PCB boards, and the height of components is lower than 10mm plug-in components can meet production requirements; however, for double-sided PCB boards with components exceeding 10mm, such as liquid crystal displays, pin headers, board connectors, etc., ordinary wave soldering machines cannot be used for automatic soldering, and manual labor is required Welding, low production efficiency, high labor costs and poor welding quality consistency

However, some selective wave soldering tooling designs in the market lack flexibility, and the product’s soldering performance is not well considered, resulting in the body floating height and skew after soldering of the plug-in components, and the selective soldering temperature cannot be monitored and alarmed in real time. , resulting in unstable performance of electronic modules
