How to avoid bruises during the quality control process of brand tag-B

Third. environment and layout management
Static electricity and dust control
Maintain the humidity in the quality control area at 40%-60%RH, equipped with ionic fan to eliminate static electricity, to prevent the label from scratching due to adsorption of dust in movement.
Cleaning: Wipe the countertop with a dust-free cloth + isopropyl alcohol before starting work every day to avoid particles embedded in the label surface.
Lighting and Visual Aid
Adoption of non-strobe LED lights (color temperature 5000K-6500K) ensures that the details of the label surface are clearly visible, and reduces touching caused by quality inspectors squinting or coming close to observe.
Example: A cosmetic labeling factory upgraded its lighting system to increase the distance between the inspector’s head and the label from 15cm to 30cm, reducing the risk of injury by 60%.
Space layout optimization
The quality inspection table is divided into inspection area, qualified product area and defective product area, and the interval of each area is ≥15cm to avoid collision of labels in movement.
Channel design: keep the width of the aisle in the quality inspection area ≥ 1m, to prevent material trucks or personnel walking when knocking over the label stack.

Fourth, the quality inspection process and packaging protection
Staged inspection strategy
The quality inspection is divided into the appearance of the initial inspection → functional testing → final re-inspection of three steps, each stage to reduce the number of label handling.
Example: an automotive tag factory through the process of reorganization, so that the average number of single piece of tag handling from 6 times down to 2 times, bruising rate decreased by 50%.
Temporary fixing and isolation
Quality inspection process using transparent acrylic separation frame, the label to be inspected vertically arranged to avoid stacking and extrusion.
Labeling: “Handle with care” labels are affixed to fragile labels (e.g., ceramic substrates), and priority is given to skilled staff for inspection.
Packaging design optimization
The use of independent foam card slot + anti-static bag packaging to ensure that the label in transit without displacement space.
Case: a medical device label through improved packaging, so that the logistics link bruise rate from 0.8% to 0.05%.
Fifth. quality traceability and continuous improvement
Bump traceability system
Record the quality inspection station, time and operator information of each label, and analyze the high-frequency problem links with the location of bruises.
Tool: Use MES system to generate heat map of bruises and locate the operation steps to be optimized.
PDCA cycle improvement
Monthly statistics on the types of bruises (e.g. scratches, indentations, deformations) and their percentage, and targeted adjustment of protective measures.
Example: A 3C parts factory analyzed and found that 60% of the bruises came from label flipping action, and then introduced an automated flipping mechanism, which reduced the bruise rate by 75%.
Through the comprehensive application of the above measures, can significantly reduce the risk of brand labeling quality inspection in the bruising, improve product yield and customer satisfaction. The actual implementation of the label according to the material, size and process complexity of targeted adjustments, and regularly review and optimize.
