System and method for supplying materials for mixed assembling production line based on RFID

Abstract

The invention discloses a system for supplying materials for a mixed assembling production line based on an RFID. A method for supplying the materials for the mixed assembling production line based on the RFID includes the steps of enabling products which are being processed and to be assembled beside the production line to be equipped with RFID labels, reading assembly information of the production line in real time through an RFID read-write device, transmitting the information to a data storage and application module through a middle part, monitoring the RFID read-write device through the data storage and application module, and obtaining a distribution scheme through the real-time assembly information. According to the system for supplying the materials, the invention further provides the method for supporting the materials. By determining the distribution lead time of the materials, the acquisition cycle of the RFID read-write device and the data taking and using middle cycle of the middle part, the required amount of the materials which are to be assembled beside the production line is obtained through the data storage and application module, and the distribution scheme is obtained according to transportation vehicles. According to the system and method, workshop assembly schedule information and assembly line state information are automatically collected, and the response capacity, the flexibility degree and the distribution efficiency of the distribution requirements of the materials beside the production line are improved.

Description

technical field [0001] The invention relates to a material supply method for a mixed assembly production line, in particular to an RFID-based material supply system and method for a mixed assembly production line. Background technique [0002] Mixed assembly line refers to the simultaneous production of multiple different models of the same product family on one assembly line, and the model of the product is determined according to the individual needs of customers. The mixed assembly line often refers to the final assembly line of mixed models, where different models are assembled on the same line. However, with the continuous expansion of the assembly production scale, the material inventory space next to the assembly line is increasingly scarce, and too many materials cannot be stored. Only small batches and frequent material replenishment can be carried out according to the material demand of the assembly line to ensure mixed assembly. Fast and efficient operation of th...

Problems solved by technology

[0007] However, there are still many problems in these material pulling solutions currently used, which cannot well meet the demand rhythm of timely and accurate material supply such as fast and efficient mixed assembly production lines and frequent changes in production status. Case

Such as: Material Andon press light system, manual line inspection to scan barcodes of empty boxes and other material pulling methods, relying too much on manual work, high cost, low degree of automation, low collection efficiency, insufficient agility, and due to subjective factors of operators It is easy to cause a series of problems such as less pulling, more pulling, wrong pulling, unbalanced pulling, etc., which affects the efficiency and accuracy of material supply; and there are workers' own reasons in the actual assembly process, as well as various other emergencies (such as machine Faults, parts quality problems, etc.), leading to inevitable fluctuations in assembly production, there is a flexible buffer zone between each section, which will inevitably lead to errors in the material pulling information generated by the PPS material pulling logic
