Description

Feeding and discharging scheduling prompting method and system for flying probe tester Technical Field The invention relates to the technical field of industrial automation, in particular to a feeding and discharging scheduling prompting method and a feeding and discharging scheduling prompting system for a flying probe tester. Background The semi-automatic flying probe tester is widely applied to a circuit board testing link. Such equipment requires manual loading and unloading by an operator. The prior art indicator light system such as the device prompts the operator to enter or exit the panel by simply flashing or extinguishing the light. For example, when the remaining test time of the board to be tested in the machine is about 20% and the feeding area is free of boards, the board feeding indicator lamp can flash to prompt feeding. However, there are significant limitations to the prior art: 1. The prompt strategy is stiff, and a fixed time threshold cannot adapt to the difference of different plate type test periods and cannot consider the difference of individual efficiency of operators. For a complex board card with long test time, the time threshold of 20% is too long, which leads to early waiting of an operator, and for Jian Shanban cards, the prompt is too late. 2. The information dimension is single, namely only qualitative prompts of operation are needed, and quantitative information of emergency degree or specific time is lacked. It is difficult for an operator to properly arrange a plurality of tasks if he cannot determine whether immediate processing is required or can be done later. 3. The system is isolated, the prompt logic only depends on the internal state of a single machine, and can not cooperate with other links of the production line, and the feeding capacity of the previous process and the receiving capacity of the next process can cause waiting or stacking among the processes to become the bottleneck of the production line. Thus, there is a great need in the art for an intelligent scheduling scheme that enables accurate predictions, personalized hints, and can be coordinated with a production system.

Through the actual test time of the different plate types of self-adaptation study, the accuracy of residual time prediction is promoted by a wide margin, the prompt opportunity is more accurate, operators have clear expectations to work arrangement through quantitative display, and the prompt opportunity is linked with a production line-level system, so that smooth linking between working procedures is realized, the overall production efficiency is improved, the equipment standby time is remarkably reduced, and the overall production efficiency is improved.
