The sensing module 72 is configured to sense the thickness of the glue 54 accumulated in the recess 46. The sensing module 72 can be glued. 54 thickness variation produces different determination signals and transmits the determination signal to the control module 71, so that the control module 71 drives the glue amount adjustment module 55 to actuate according to the determination signal to adjust the glue application amount of the glue application device 5. . Thereby, it is possible to effectively prevent the glue 54 from overflowing to the left and right sides of the surface 21 of the base film 2 and further infiltrating into the passage 44 between the first roller 41 and the second roller 42, and preventing the glue 54 from passing through the outer circumferential surface 411 of the first roller 41.

Glue 54 The more the amount accumulated in the groove 46, the glue 54 will flow toward the both side edges 22 of the base film 2 and the both end faces 412 of the first roller 41. Therefore, the position design of the two sensing heads 722 can be effective. The degree of change in the amount of glue 54 accumulated in the groove 46 is sensed.

A lower limit set value and an upper limit set value are set in the control element 723. A vertical distance between the initial contact position P of the outer peripheral surface 411 of the first roller 41 and the surface 21 of the base film 2 (that is, the bottom end of the recess 46) to the liquid surface 541 of the glue 54 accumulated in the recess 46 is defined. D is the thickness accumulated by the glue 54, and the lower limit setting value of the present embodiment is such that the vertical distance D is set to, for example, 5 mm, and the upper limit setting value is set such that the vertical distance D is set to, for example, 10 mm.

An ultrasonic wave is emitted, and when the ultrasonic wave hits the initial contact position P, it is reflected back to the sensing head 722 and received by the sensing head 722. The sensing head 722 generates a sensed value and transmits it to the control element 723 via the transmission line 724. The control element 723 compares the sensed value with the lower limit set value and the upper limit set value. Since the glue head 52 has not started to apply the glue 54, and the glue 54 is not accumulated in the groove 446, the control element 723 determines that the sensed value is less than the lower limit set value, thereby generating a corresponding determination signal.

In turn, a corresponding judgment signal is generated. The control component 723 transmits the determination signal to the control module 71. The control module 71 maintains the glue amount adjustment module 55 in the open state according to the determination signal, so that the glue application head 52 of the glue application device 5 continues to apply the glue. 54 is on the surface 21 of the base film 2. At the same time, the control module 71 drives the rotation speed adjustment module 73 to increase the rotation speed of the drive motor 34 to a predetermined rotation speed according to the determination signal. The drive wheel 33 can drive the base film 2 to move at a relatively fast speed. Thereby, the amount of the glue 54 coated on the surface 21 of the base film 2 can be reduced.

Referring to FIG. 2, FIG. 3 and FIG. 5, when the glue 54 in the groove 46 accumulates to the thickness shown in FIG. 5, the control element 723 determines that the sensed value returned by the sensor head 722 is equal to the upper limit set value. In turn, a corresponding judgment signal is generated. The control component 723 transmits the determination signal to the control module 71. The control module 71 drives the glue amount adjustment module 55 to close according to the determination signal, so that the glue head 52 stops the glue application 54. At the same time, the control module 71 drives the rotation speed adjustment module 73 to maintain the drive motor 34 at a predetermined rotation speed according to the determination signal, so that the transmission wheel 33 drives the base film 2 to move at a predetermined rotation speed. Thereby, the amount of glue 54 accumulated in the groove 46 can be reduced.

Referring to FIG. 2, FIG. 3 and FIG. 9, when the glue 54 in the groove 46 is accumulated to the thickness shown in FIG. 9, the control element 723 determines that the sensed value returned by the sensor head 722 is greater than the upper limit setting value. In turn, a corresponding judgment signal is generated. The control component 723 transmits the determination signal to the control module 71.
