Cleaning management method and system for sorting machine

Abstract

The invention provides a cleaning management method and system for a sorting machine. The cleaning management method comprises the steps of firstly acquiring the type of a product to be sorted; then,judging whether the current product type is consistent with the last product type through an EAP central control system or not; automatically generating an automatic clearing instruction, a printing template clearing instruction and a printing template re-matching instruction through the EAP central control system if the product types are inconsistent; outputting TTL pulse signals according to theautomatic clearing instruction to the sorting machine through the control module for cleaning operation; and controlling a printer through a printing control terminal to remove the previous printingtemplate, and printing according to the rematched printing template. According to the cleaning management method, automatic clearing and automatic switching of printing templates are achieved, and theproduction efficiency is improved; and production errors are reduced.

Description

technical field [0001] The invention relates to the technical field of chip testing, in particular to a sorting machine cleaning management method and system. Background technique [0002] In chip production, the packaged chip needs to be tested as a finished product. Finished product testing refers to the functional and electrical parameter testing of the packaged chips through the combined use of the sorting machine and the testing machine. The pins of the chip are connected to the functional modules of the testing machine through the base on the test station and the dedicated connection line. The testing machine applies input signals to the chip and collects output signals to judge whether the function and performance of the chip meet the design specification requirements. After the test, the chips are sent to the sorting machine. The sorting machine performs appearance inspection and laser marking to mark the product code of the chips, and then sorts, collects or tapes....

AI Technical Summary

Problems solved by technology

However, the existing sorting equipment (Handler) cannot realize the function of automatic machine cleaning and automatic selection of printing templates. Every time the product model is switched, it can only be manually operated to check and remove residual materials and switch printing templates. The production efficiency is low. , due to the negligence of the operator, it is easy to have the situation that the printing code is not switched, the remaining material is not cleared, printing code printing errors, and material mixing problems occur, which will affect the production capacity of the equipment and the quality of the product
