Module for adding protective agents to contacts and automatic assembly machine and assembly method for contacts

Abstract

The invention discloses a module for adding protective agents to contacts and an automatic assembly machine and assembly method for the contacts. The module for adding the protective agents to the contacts comprises a contact arrangement machine and a touch feeding machine, wherein one end of the touch feeding machine is connected with the touch arrangement machine, and the other end of the touch feeding machine can be connected with a contact assembly station; a protective agent pouring device used for adding the protective agents to the contacts and a drying device used for drying the contacts to which the protective agents are added are arranged at corresponding positions of a conveying belt of the contact feeding machine. The automatic assembly machine for the contacts comprises the contact assembly station and the module for adding the protective agents to the contacts, wherein the module for adding the protective agents to the contacts is connected with the contact assembly station which is provided with an assembly machine structure. The assembly method for the contacts includes the steps that the contacts to be assembled are sequentially arranged in the state that the contacts can be conveniently assembled, the contacts are conveyed to the assembly station through a conveying device, the protective agents are painted on the contacts in the conveying process, and then the contacts are assembled to a contact support. According to the module for adding the protective agents to the contacts and the automatic assembly machine and assembly method for the contacts, the protective agents are added to the contacts in the conveying process after the contacts are arranged and before the contacts are assembled, and mutual friction between the contacts is avoided after the protective agents are added to the contacts.

Description

technical field [0001] The invention belongs to the field of low-voltage electronic processing, and relates to an automatic contact assembly machine, an assembly method and a contact protection agent module. Background technique [0002] The existing process assembles the contact with the silver point and the contact support. Usually, the component supplier soaks the contact in the protective agent solution and dries it after the components are processed separately, and then vacuum packs and ships to The factory then assembles the contacts to the contact support. During the transportation and assembly of the contacts after adding the protective agent, it is inevitable that the silver dot protective layer will be scratched and broken due to the mutual friction of the parts. The contacts mentioned here include static contacts, contact bridges and other components with silver dots that need to be added with a silver dot protection layer. There are two assembly modes for existi...

Problems solved by technology

These two assembly modes are carried out after the parts supplier completes the silver point of the contact bridge or the contact and adds the protective agent. In the subsequent assembly process, it is inevitable that the contact bridge or the contact will rub against each other, resulting in the silver point protective layer. Scratches and cracks; especially in the automatic assembly mode, automatic alignment is required, which can easily cause scratches and cracks on the silver dot protective layer
