1.Industry Background
In PCB automated production lines, transmission systems are critical for stable board movement through AOI, exposure, etching, cleaning, and printing stages. As PCB designs move toward ultra-thin and high-precision circuits, transmission components must maintain high wear resistance, precise alignment, and long-term stability.
2.Common Transmission Problems in PCB Lines
Problem 1: Board deviation and vibration
Severe wear of transmission rollers leads to uneven support force, causing panel misalignment and vibration during AOI inspection and exposure processes.
Problem 2: Sliding and board stacking
Aging rubber rollers and uneven belt tension reduce friction stability, resulting in frequent slipping, stoppage, and panel accumulation.
Problem 3: Excessive noise and line instability
Insufficient transmission gear precision increases backlash and vibration, affecting overall line stability.
Problem 4: High maintenance frequency
Short bearing and bushing lifespan under continuous operation raises daily maintenance costs and downtime risk.
3.Engineering Causes Behind Transmission Failures
Long-term exposure to moisture and chemical residues accelerates material wear
Inconsistent friction coefficients in aging rollers cause unstable torque transfer
Gear backlash and bearing clearance increase vibration at high speeds
