In a specific application, the second mounting seat 60 is located above the first mounting seat 50, and then the second tape splicing mechanism 30, the glue preparation mechanism 20 and the second pressing plate 42 are located above the first tape splicing mechanism 10 and the second pressing plate 42, so that the pressing mechanism applies a force to the material tape. At this time, the thickness direction of the material belt is parallel to the up-down direction, and the conveying direction of the material belt is perpendicular to the up-down direction. The X direction in fig. 1 is the tape conveying direction, and the Y direction in fig. 1 is the thickness direction.

In some embodiments, the first suction plate 11 and the second suction plate 31 are capable of generating a relative motion in the web conveying direction, so that the first suction plate 11 and the second suction plate 31 are switched between the first state and the second state. Thus, when the first suction plate 11 and the second suction plate 31 are in the first state, the first suction plate 11 and the second suction plate 31 can generate relative movement in the thickness direction and clamp the first material tape 200 in cooperation with each other, so that the first material tape 200 is cut, and the second suction plate 31 can also place the second material tape 300 on the side of the adhesive tape 400 facing away from the first material tape 200. When the first suction plate 11 and the second suction plate 31 are in the second state, the first suction plate 11 and the second suction plate 31 allow the first pressing plate 41 and the second pressing plate 42 to generate relative movement in the thickness direction to press the first material tape 200 and the second material tape.

Further, the first suction plate 11 is fixed in the web conveying direction, and the second suction plate 31 is movable in the web conveying direction so as to generate relative movement with the first suction plate 11.

Specifically, the fourth driving assembly 33 adopts a motor and screw transmission mode to drive the second suction plate 31 to move in the material belt conveying direction.

In other embodiments, the second suction plate 31 may be fixed in the web conveying direction, and the first suction plate 11 may be movable in the web conveying direction so as to generate a relative movement with the second suction plate 31. The first tape splicing mechanism 10 further includes a third driving assembly, where the first suction plate 11 is connected to the third driving assembly, and the third driving assembly can drive the first suction plate 11 to move in the tape conveying direction, so that a relative movement is generated between the second suction plate 31 and the first suction plate 11.

Referring to fig. 4, the second tape splicing mechanism 30 further includes a rotating assembly 34, the rotating assembly 34 is disposed on the second driving assembly 32, and the second suction plate 31 and the glue preparation mechanism 20 are both mounted on the rotating assembly 34. The fourth driving component 33 can drive the rotating component 34 to move in the material belt conveying direction, so as to drive the second suction plate 31 and the glue preparation mechanism 20 to move in the material belt conveying direction. The rotating assembly 34 can drive the second suction plate 31 and the glue preparation mechanism 20 to rotate, so that one of the second suction plate 31 and the glue preparation mechanism 20 rotates to face the first suction plate 11. Specifically, the rotating assembly 34 drives the second suction plate 31 and the glue preparation mechanism 20 to rotate by adopting an air cylinder.

Referring to fig. 4, when the second suction plate 31 faces the first suction plate 11, the first material tape 200 can be clamped in cooperation with the first suction plate 11, or the second material tape 300 can be placed on the side of the adhesive tape 400 facing away from the first adhesive tape 400. Referring to fig. 7, when the glue preparation mechanism 20 faces the first suction plate 11, the glue preparation mechanism 20 can place the adhesive tape 400 on the first material tape 200. In some embodiments, the rotation assembly 34 is rotated by 90 ° to switch one of the second suction plate 31 and the glue preparation mechanism 20 from facing the first suction plate 11 to facing the other one of the second suction plate 11. It should be appreciated that in other embodiments, the rotating assembly 34 can also be rotated by other angles to effect corresponding switching, which is not limited herein.

Here, the meaning that the second suction plate 31 faces the first suction plate 11 is: the adsorption surface of the second suction plate 31 for adsorbing the second material tape 300 faces the adsorption surface of the first suction plate 11 for adsorbing the first material tape 200, and the glue preparation mechanism 20 faces the first suction plate 11 means that: the pick-up surface of the tape 400 picked up by the tape preparation mechanism 20 faces the first suction plate 11 for sucking the suction surface of the first tape 200.

The above arrangement can realize the free switching between the second suction plate 31 and the glue preparation mechanism 20 through the rotating assembly 34, ensure the sequential placement of the adhesive tape 400 and the second material tape 300, and improve the working efficiency.

The glue preparation mechanism 20 includes a glue preparation plate on which the adhesive tape 400 is placed in advance by a person, and the glue preparation plate can adsorb the adhesive tape 400 by an adsorption force.
