[0023] As Figure 1-6 shown, an automatic tape sticking device on a film includes a film conveying mechanism 1 and a transverse moving wallboard 3 that is arranged above the film conveying mechanism 1 through a cross beam 2 and can move left and right along the cross beam 2. On the transverse moving wallboard 3, a tape unwinding mechanism 4, a tape pressing mechanism 5, and a tape release liner winding mechanism 6 are sequentially arranged from left to right in cooperation. The tape unwinding mechanism 4 is used to supply a tape 7 to the tape pressing mechanism 5. The tape 7 includes an adhesive layer 7.1 and a release liner 7.2. The adhesive layer 7.1 is an adhesive layer with a segmented structure; the tape pressing mechanism 5 includes a cam 8 whose pin shaft is arranged on the transverse moving wallboard 3 and is driven to rotate by a servo motor, and a tape pressing head unit located below the cam 8 and driven by the cam 8. The tape pressing head unit includes a pressing rod 9 located above and a pressing head 10 located below. On the transverse moving wallboard 3, corresponding to the backs of the pressing rod 9 and the pressing head 10, a vertical guide rail 11 is arranged. The pressing rod 9 and the pressing head 10 are both provided with sliding grooves on their backs that cooperate with the vertical guide rail 11, so that the pressing rod 9 and the pressing head 10 can move up and down along the vertical guide rail 11 to achieve accurate and stable movement; between the pressing rod 9 and the pressing head 10, a connecting spring 12 is arranged. Around the connecting spring 12 between the pressing rod 9 and the pressing head 10, several sliding pull rods 13 are also arranged for pulling the pressing head 10 to reset and guiding the movement of the pressing head 10; on both sides of the pressing rod 9, a pressing plate 9.1 extends respectively. Below the two pressing plates 9.1 on the transverse moving wallboard 3, a boss 3.1 is also arranged respectively. Between the pressing plate 9.1 and the boss 3.1, a pressing rod return spring 3.2 is also arranged.
[0024] The transverse moving wallboard 3 is fixedly connected to the moving end of a linear driving mechanism 14 arranged on the cross beam 2 to achieve left and right movement along the cross beam 2, and further achieve alternating left and right position pressing and gluing of the tape pressing mechanism 5 on the film 15.
[0025] The linear driving mechanism 14 is a screw nut sleeve linear driving mechanism including a screw rod, a nut sleeve, and a guiding rod. The screw rod 14.1 on the screw nut sleeve linear driving mechanism is driven to rotate by a servo motor fixedly arranged on the cross beam.
[0026] Above one of the pressing plates 9.1 on the transverse moving wallboard 3, a reset limiting plate 3.3 is also arranged to prevent the pressing rod 9 from being over - reset and hitting the cam 8.
[0027] At the top of the pressing rod 9, a roller 9.2 is provided through a pin shaft. The pressing rod 9 contacts the cam 8 through the roller 9.2, thereby protecting the cam 8 and the pressing rod 9 and reducing friction.
[0028] The tape release layer winding mechanism 6 includes a guide roller, a tensioning unit, and a release layer winding roller 6.1. The tensioning unit includes a rocker arm 6.2 provided on the transverse moving wall plate 3 and a tensioning roller 6.3 provided at one end of the rocker arm. The other end of the rocker arm 6.2 is connected to a tensioning spring 6.4 fixed on the transverse moving wall plate 3, thereby achieving a tensioning effect. Specifically, when the tension increases, the tensioning roller 6.3 is lifted upward, and the tensioning spring 6.4 is pressed downward. When the tension decreases, under the restoring force of the tensioning spring 6.4, the tensioning roller 6.3 is pulled downward until the tension returns to normal.
[0029] Working process:
[0030] The film conveying mechanism 1 conveys the film 15 to below the tape pressing mechanism 5. The tape unwinding mechanism 4 supplies the tape to below the pressing head of the tape pressing mechanism 5. The supplied tape 7 is a tape including an adhesive layer 7.1 and a release layer 7.2 whose adhesive layer 7.1 has been previously segmented into sections. The tape release layer winding mechanism 6 is used to wind and recycle the release layer after the adhesive layer and the release layer of the tape pass through the tape pressing mechanism and are separated.
[0031] During the tape pasting process, by controlling the rotation of the cam 8, the tape pressing head unit located below it is controlled to be in the upper position where no tape is pasted and the lower position where tape is pasted. When tape pasting is required, the wide side of the cam 8 contacts the tape pressing head unit. When tape pasting is not required, the narrow side of the cam 8 contacts the tape pressing head unit. When a longer tape needs to be pasted, the pressing time is correspondingly increased. When a shorter tape needs to be pasted, the pressing time is correspondingly shortened. By controlling the left - right moving distance of the transverse moving wall plate 3 relative to the cross beam 2, the left - right position of the pressing head 10 relative to the film 15 is controlled. Thus, tape can be pasted alternately left and right on the film 15, or tape can be pasted at the required position as needed.
[0032] In addition, through the setting of the vertical guide rail 11, the movement of the pressing rod 9 and the pressing head 10 can be made more accurate and stable. Through the setting of the connecting spring 12, the pressing head 10 can more flexibly adapt to the thickness fluctuation of the film 15 after being pressed down to ensure smooth tape pasting in place. Through the setting of the sliding pull rod 13, the pressing down and resetting of the pressing head 10 can be made more stable and rapid. Through the setting of the pressing rod return spring 3.2, the return of the pressing rod 9 can be made more rapid.
[0033] The automatic tape - sticking device on the film of the utility model has a clever structure. Driven by the transverse - moving wallboard and pressured by the tape - pressing mechanism, it can stick tapes on the film according to requirements in terms of the front - to - back, left - to - right distances and length needs. The tape - sticking speed is fast, which greatly improves the production speed and the flexibility of tape - sticking, reduces the labor cost, lightens the operation burden of workers, and reduces problems such as tape - sticking deviation caused by human factors. It can be widely applied to scenarios that require precise tape - sticking in industries such as packaging, printing, and electronics. It has strong practicability and is worthy of promotion.
[0034] The utility model is not limited to the foregoing specific embodiments. The utility model extends to any new feature disclosed in this specification or any new combination, as well as any new method or process step disclosed or any new combination.
