Description

Machined workpiece information traceability system and information traceability control method

technical field

The invention relates to an information traceability system and an information traceability control method for machining workpieces.

Background technique

In the field of machinery manufacturing, the traceability transmission system of machining workpiece information is more and more widely used. During the implementation of the assembly line information traceability transmission system, the current main traceability information transmission carriers are RFID electronic tags and self-adhesive paper labels.

The process of using the RFID electronic tag is: (1) Put the RFID electronic tag on the data reader → (2) Write the traceability serial number into the RFID electronic tag → (3) Adsorb the RFID electronic tag to the upper part of the workpiece and transfer it to the lower part A processing site → (4) align the RFID electronic tag with the data reader to read the serial number → (5) save the read serial number and processing data in the traceability system database → (6) align the RFID electronic tag and the workpiece Flow to the next processing station and repeat steps (3), step (4) and step (5) → (7) RFID electronic tag and workpiece flow to the final processing station → (8) Align the RFID electronic tag to the data reader, Read the serial number and print the customer paper label → (9) Upload the serial number of the RFID electronic label and the serial number of the customer paper label to the traceability system database → (10) Remove the RFID electronic label and clear the serial number in it for the next time Recycling; and paste the customer paper label on the designated position of the workpiece to complete the workpiece processing.

There is a magnet in the RFID electronic tag, which is adsorbed on the workpiece. It has the advantages of convenient sticking and removal, and reusability. However, compared with the reading of paper tags, the information reading speed is slow and misreading is easy to occur (in step (4) Among them, if two RFID electronic tags are close to each other, it is easy to misread), and there are disadvantages such as limited service life and high cost.

The process of using the self-adhesive paper label is: (1) The printer prints out the self-adhesive paper label with a unique QR code serial number → (2) Paste the paper label on the workpiece → (3) Scan the paper label with a scanner Read the serial number on the QR code → (4) Save the read serial number and processing data into the traceability system database → (5) Transfer the self-adhesive paper label and workpiece to the next processing station and repeat the steps ( 3) and step (4) → (6) The self-adhesive paper label and the workpiece flow to the final processing station → (7) Scan the QR code on the paper label with a scanner, read the serial number, and print the customer paper label → (8) The self-adhesive label serial number and the customer paper label serial number are uploaded to the traceability system database in a chain → (9) Remove the self-adhesive paper label and discard it; and paste the customer paper label on the designated position of the workpiece to complete the workpiece processing.

Self-adhesive paper labels have the advantages of fast reading speed and are not easy to be misread; however, they cannot be reused, are difficult to paste and remove, and are prone to leave residual glue on the surface of the workpiece, and they cannot be used for workpieces with oily surfaces.

In view of the shortcomings of the above two information retrospective transmission systems, it is necessary to develop a new type of retrospective data transmission system that has the advantages of the above two information retrospective transmission systems and can eliminate their shortcomings.
