Thus, one side edge of the cover tape 22 away from the limiting end can be effectively abutted against the step surface, and the cover tape 22 is prevented from shaking.

Alternatively, considering that a passage is defined between the wall surface of the stopper groove 111, the surface of the cover plate 12 facing the stopper groove 111, and the wall surface of the stopper mechanism 13 facing the stopper groove 111, a step surface may be formed on the groove wall surface of the stopper groove 111 on the higher side of the groove wall surface, and of course, may be formed on the cover plate 12 (refer to fig. 2).

In the present application, at least the outer peripheral surface of the stopper 132 housed in the housing section 1311 is fitted to the inner wall surface of the housing section 1311. In this way, since the braid 20 moves along the extending direction of the channel and the moving direction of the stopper 132 is perpendicular to the extending direction of the channel, the outer circumferential surface of the stopper 132 is fitted to the inner wall surface of the accommodating portion 1311, which also can effectively limit the stopper 132, thereby ensuring that the stopper 132 can move smoothly along the direction of the elastic force of the elastic member 133.

Further, as shown in fig. 3, the end of the stopper block 1323 on the braid 20 side is in a semicircular arc shape.

As shown in fig. 1, the braid encapsulating device further includes an encapsulating module 30, the encapsulating module 30 is connected with the base 10, a sealing knife 31 is provided at a side of the encapsulating module 30 facing the base 10, and an avoiding via 121 is provided at a position of the channel opposite to the sealing knife 31; the sealing knife 31 is arranged in a liftable manner relative to the base 10, the sealing knife 31 has a working position for sealing the braid 20 by passing through the avoiding through hole 121, and the sealing knife 31 has an avoiding position for exiting the avoiding through hole 121. In this way, the cover tape 22 and the carrier tape 21 are heat-sealed by the sealing blade 31 through the escape through hole 121, and the chip 23 is sealed between the cover tape 22 and the carrier tape 21.

In the present application, the package module 30 is provided to be movable up and down on the base 10. Thus, the up-and-down movement of the sealing knife 31 is carried by the up-and-down movement of the encapsulation module 30.

It should be noted that, in this embodiment, in consideration that the chip 23 needs to be sealed between the carrier tape 21 and the cover tape 22, in order to ensure the sealing reliability of the two to the chip 23, the parts of the carrier tape 21 and the cover tape 22 located outside the chip 23 in the width direction need to be sealed, so that the sealing knives 31 are two sealing knives 31 arranged in parallel, since the cover plate 12 covers a part of the limiting groove 111, one sealing knife 31 of the two sealing knives 31 needs to pass through the avoiding through hole 121 to perform the sealing operation, and the other sealing knife 31 of the two sealing knives may directly contact the cover tape 22 to perform the sealing operation.
