When the foil is being wound, the winding unit 260 can wind the foil, and the detection unit 220 detects the tension of the foil during winding, and the torque unit 250 provides torque for the foil during winding. The foil can be wound more tightly by the detection unit 220 and the torque unit 250, so as to avoid winding looseness and air bubbles, and the limiting unit 230 limits the two sides of the conveyed foil, and the deviation correction unit 240 corrects the deviation of the conveyed foil. The limiting unit 230 and the deviation correction unit 240 can avoid the deviation of the foil during winding, so as to make the side edges of the wound foil flat and consistent, thereby improving the winding effect of the foil.

[0029] In addition, in order to facilitate winding of the foil after surface treatment, the conveying rollers 270 are arranged at the limiting unit 230 and the rear side of the limiting unit 230. The foil is conveyed by the conveying rollers 270, so that the foil can be conveyed smoothly, thereby facilitating winding of the foil.

[0030] The foil surface treatment unwinding and winding mechanism in the embodiment is designed as a multi-station, and a plurality of sets of unwinding and winding are arranged, so that a plurality of foils can be unwound, surface treated and wound at the same time, thereby improving the production efficiency of the foils.

[0036] The deviation correcting sensor 243 in the embodiment is an ultrasonic sensor or an infrared sensor, the deviation correcting sensor 243 tracks the position of the edge or line of the foil by using ultrasonic waves or infrared rays to monitor the deviation degree of the foil.
