Fig. 4 is a perspective view of a head assembly in a vertical rolling type double-sided laminating machine according to the present invention; figure 5 is a perspective view of a roll press assembly in a vertical roll press type double-sided laminating machine according to the present invention.

The mounting head assembly 31 comprises a main body 311, a slide rail 312 arranged along the main body 311 in the up-down direction, and a mounting head 313 and a visual positioning element 314 which can slide along the slide rail 312 in the up-down direction, preferably, the slide rail 312 is a high-precision heavy-duty linear slide rail, so as to improve the structural strength and the fitting precision of the mounting assembly 31; the visual positioning member 314 and the mounting head 313 are relatively stationary, and thus, the mounting head 313 and the cover film can be precisely positioned by the visual positioning member 314.

In operation, the mounting head 313 moves down along the slide rail 312 to the fly stripping assembly 24, after the mounting head 313 and the cover film are positioned, the cover film is adsorbed to the mounting head 313 by forming a vacuum on the opposite side of the mounting head 313 from the side opposite to the cover film, and then the mounting head 313 moves up along the slide rail 312 to the position opposite to the inner copper, and the mounting head 313 attaches the cover film to the surface of the inner copper along with the movement of the mounting head assembly 31 to the left or the right.

As shown in fig. 2, the inner copper supply part 2c includes an inner copper supply member 26 and a cleaning member 25 which are disposed opposite to each other in the vertical direction, and the cleaning member 25 removes static electricity and dust from the surface of the inner copper by using an ion wind bar and a dust-sticking roller, respectively, to ensure that the surface of the inner copper is free from static electricity and dust before being attached to the cover film.

The copper of the inner layer to which the coverlay is applied passes through the rolling assembly 32 to form a finished product, and then is recovered by the finished product recovery mechanism 4, preferably, at least a part of the finished product recovery mechanism 4 is located outside the frame 1 in the left-right direction, and more preferably, the finished product recovery mechanism 4 located outside the frame 1 does not exceed the range of the coverlay feeding member 21 or the coverlay scrap recovery member 22, so as to ensure that the size of the laminator 10 in the left-right direction can be effectively controlled.

Further, in order to prevent the cover film from being damaged, generally, when the inner layer copper pre-attached with the cover film passes through the rolling mechanism 3, the outer surface of the cover film is further covered with a layer of tape guide film, as shown in fig. 2, the attaching machine 10 further includes a tape guide film feeding member 5 disposed adjacent to the rolling mechanism 3, similarly, along the left and right direction, two opposite tape guide film feeding members 5 are disposed opposite to each other, and the tape guide film is attached to the outer surface of the cover film when passing through the rolling mechanism 3.

However, according to the structural layout of the laminator 10 described in the present invention, when the laminating mechanism 3 is located below the feeding mechanism 2, the inner copper layer and the covering film can still be laminated in the vertical direction at the same time, and at this time, in addition to the need to exchange the positions of the laminating mechanism 3 and the feeding mechanism 2, the position of the finished product recycling mechanism 4 can be readjusted according to the overall layout need of the laminator 10.
