Description

Technical Field

[0001] The present invention relates to the technical field of drive shaft production, in particular to an automatic labeling device for a drive shaft. Background Art

[0002] Driveshafts are key components in automotive drivetrains. During production, they require gaskets to be assembled and labels to record traceability information. Traditional manual processes can lead to issues such as missing or over-installing gaskets, missing labels, or incorrect information (such as illegible text). These issues can cause unusual noises when starting the vehicle and hinder subsequent traceability, impacting customer satisfaction. Therefore, automated driveshaft labeling systems are primarily used in the production of automotive driveshafts, improving assembly and labeling quality through automation. Currently, driveshaft labeling involves manually removing the workpiece RFID tag and placing it on an RFID reader / writer after the driveshaft assembly arrives at the labeling station. After confirming the previous steps are successful, a printer automatically prints a label, which is then scanned manually with a barcode scanner. Once the label passes, the label is manually removed from the backing paper and affixed to the driveshaft assembly according to the documented location. This approach is inefficient and fails to meet production requirements. Therefore, an automated labeling system is needed. Prior art patent CN106112557B discloses equipment for assembling gaskets and labeling driveshafts. However, this patent does not disclose the specific process for removing, transferring, and re-labeling the label, making a solution to this issue crucial. Summary of the Invention
