Through forming sealed clearance between making two adjacent lamination, can make the inserted sheet 33 when keeping away from the direction displacement of lamination, produce the negative pressure in making the clearance between two adjacent lamination, and then make the insulating glue of fluid state fill into former inserted sheet 33 position earlier, solved only that the insulating glue that the pressurization was filled the existence leaks from the junction of embedment container earlier and appears overflowing and fill into former inserted sheet 33 department after, avoided the air to get into former inserted sheet 33 and appear the bubble, lead to the problem that bonding strength reduces.

In a further embodiment, the need to provide one tab 33 between every two adjacent laminates requires one tab 33 for each displacement assembly, but this solution has the problem of excessive cost due to the use of multiple displacement assemblies.

In order to solve the above problem, the second displacement assembly 31 is a linear motion mechanism disposed on one side of the glue container 1, and as shown in fig. 5, the second displacement assembly 31 is a screw mechanism, and when a lamination linear motion mechanism is inserted for a predetermined distance, the abutment rod 321 abuts against the insert 33, so that the insert 33 is inserted.

When the abutting rod 321 abuts against the inserting sheet 33, the inserting sheet 33 extends into the accommodating cavity.

When the contact rod 321 is separated from the insertion sheet 33, the elastic member 322 drives the insertion sheet 33 to move toward the end away from the receiving cavity.

Through elastic component 322 and the one end butt pole 321 that is the taper, can use a displacement subassembly to realize that the order of inserted sheet 33 inserts, and the process that the order withdrawed from, very big reduction manufacturing cost.

In the above embodiments, the cooperation of the first displacement assembly 21, the second displacement assembly 31 and the lifting assembly 14 may be controlled using a vision device electrically connected to the first displacement assembly 21, the second displacement assembly 31 and the lifting assembly 14 as a sensor.

In the above embodiment, after the lamination is placed into the accommodating cavity, the lower die base 11 and the upper die base 13 are abutted to form a sealed accommodating cavity, then the input assembly 4 is used to inject the insulating glue into the sealed accommodating cavity, in the process of injecting the insulating glue, the vacuum assembly 5 is preferably used to enable the sealed accommodating cavity to be in a negative pressure state to reduce air bubbles in the insulating glue, after the insertion sheet 33 is pulled away, a predetermined negative pressure state can be maintained to ensure the air bubbles to be discharged, and in the preferred embodiment, the output end of the input assembly 4 and the input end of the vacuum assembly 5 can be correspondingly matched with the gap space of the lamination.
