Mould processing production line internet of things system and production control method

Abstract

The invention discloses a mould processing production line internet of things system comprising ultrahigh-frequency RFID tags, ultrahigh-frequency RFID reader-writers, reader-writer antennas, a reader-writer activation device, a handheld reader-writer and an internet of things monitoring computer. The ultrahigh-frequency RFID tags are adhered on a processing component. The reader-writer antennas are fixed on the internal side wall of processing equipment and are connected with the ultrahigh-frequency RFID reader-writers. The reader-writer activation device is connected with the ultrahigh-frequency RFID reader-writers. The handheld reader-writer is used for reading the ultrahigh-frequency RFID tags on the processing component in a workshop material preparation area, a processing component cache area and an assembling area. The internet of things monitoring computer is connected with the ultrahigh-frequency RFID reader-writers and the handheld reader-writer through the network. A barcode technology and a high-frequency RFID tag technology are replaced by an ultrahigh-frequency RFID tag technology so that manual operation can be reduced, influence of artificial factors can be avoided and the degree of transparency and automation of the processing course can be enhanced.

Description

technical field [0001] The invention belongs to the field of Internet of Things systems, and more specifically, relates to an Internet of Things system and a production control method of a mold processing production line. Background technique [0002] Mold companies mainly use a manufacturing system composed of discrete equipment such as CNC milling machines, electrical processing equipment, and grinding machines to complete the processing tasks of molds, and manually perform the transfer of workpieces between various equipment. Due to the randomness of mold orders and the frequency of changes, the production process of molds is dynamic and changeable. Real-time grasp of the status of processed parts on the processing line allows the mold production management system to control and change the mold production process in a timely manner. The quality of mold processing and shortening the production cycle of molds are of great significance. [0003] The technology that connects...

Problems solved by technology

[0004] However, the existing RFID technology still has the following defects or deficiencies: These RFID technologies generally use high-frequency RFID, and the reading distance is short, so manual operation is still required, and workers are required to hold the workpiece with the RFID tag against the RFID to read and write On the reader, or the worker holds a handheld RFID reader to read and write the RFID tag on the workpiece, human error is still inevitable

However, UHF RFID signals are susceptible to interference, and its application in metal environments is limited. Therefore, UHF RFID technology has almost never been applied in the field of machining
