Winding type flexible printed circuit board tape transferring system

A winding type flexible printed circuit board tape transferring system comprising:

• a rack;
• a tape let-off wheel unit mounted on said rack, said tape let-off wheel unit comprising a let-off wheel controlled to let off a flexible printed circuit board tape;
• a tape take-up wheel unit mounted on said rack, said tape take-up wheel unit comprising a take-up wheel controlled to take up the flexible printed circuit board tape from said tape let-off wheel unit;
• two idle wheel units respectively mounted on said rack, said idle wheel units each comprising an idle wheel adapted to guide movement of the flexible printed circuit board tape from said tape let-off wheel unit toward said tape take-up wheel unit;
• a tension control wheel unit mounted on said rack and arranged between said idle wheel units, said tension control wheel unit comprising a tension wheel- moved to control the tension of the flexible printed circuit board tape being transferred from said tape let-off wheel unit toward said tape take-up wheel unit;
• and
• at least one work wheel unit mounted on said rack and arranged between said idle wheel units, said at least one work wheel unit each comprising a work wheel disposed in contact with the flexible printed circuit board tape being transferred from said tape let-off wheel unit toward said tape take-up wheel unit and forced to rotate upon movement of the flexible printed circuit board tape, and a rotary encoder coupled to said work wheel for synchronous rotation with said work wheel to detect the position of the flexible printed circuit board tape being transferred from said tape let-off wheel unit toward said tape take-up wheel unit and to output a signal to a control unit indicative of the position of the flexible printed circuit board tape.
