The label offset may be caused by the following reasons: The shape of the bottles is irregular: for elliptical bottles or those with deformed shapes, the grasping mechanism's elasticity needs to be adjusted. The material properties of the labels: paper labels are susceptible to humidity and should be operated in a constant temperature and humidity workshop; plastic labels need to control static electricity. Mechanical transmission errors: wear of synchronous belts or delayed response of servo motors can cause position deviations. The solutions include: Visual inspection system: install cameras to provide real-time feedback on label positions and automatically correct the angle of the labeling head. Pre-stretching technology: moderately stretch the labels to counteract the size changes caused by the bottle's contraction. Regular calibration: use laser rangefinders to check the positioni
