At this time, the first left apron 35 , the first right apron 36 , the second left apron 55 and the second right apron 56 are all squeezed and deformed. Start the drive mechanism 1. At this time, the main pressure wheel 21 and the main transmission gear 22 rotate together with the output shaft of the drive mechanism 1. The main transmission gear 22 can drive the first transmission gear 37 and the second transmission gear 57 to rotate synchronously. What needs to be explained Yes, the front end of the COF carrier tape 4 is wound by other equipment (such as the driving wheel of testing equipment or packaging equipment), and the speed at which the COF carrier tape 4 moves is preferably the same as the speed at which the main pressure roller 21 rotates, which can further ensure the COF The stability of the transport of the carrier tape 4 can be prevented, and the COF carrier tape 4 can be prevented from being damaged.

The present invention can realize the straight line or curved transport of the COF carrier tape 4 through the driving mechanism 1, the main transmission mechanism 2, the first auxiliary transmission mechanism 3 and the second auxiliary transmission mechanism 5, so as to meet different requirements. Moreover, the first auxiliary transmission mechanism 3 and the second auxiliary transmission mechanism 5 cooperate with the main transmission mechanism 2 respectively, and can press both sides of the edge of the COF carrier tape 4 to ensure the stability of the COF carrier tape 4 during the conveying process. sex. At the same time, the present invention uses extrusion force to compress the COF carrier tape 4, which can prevent the COF carrier tape 4 from being torn due to ratchet teeth and improve the yield of the COF carrier tape 4.
