As shown in fig. 1 to 3, the double-sided cover film laminator according to the embodiment of the present invention includes two laminating modules 100, two cover film feeding modules 200, a circuit board feeding and discharging module 300, and a frame 400, where the two cover film feeding modules 200 are configured to respectively feed sheet-shaped cover films to the two laminating modules 100; the circuit board loading and unloading module 300 includes a loading and unloading robot 310 and two circuit board stacking assemblies 320, wherein the loading and unloading robot 310 is used for supplying the circuit board to be film-pasted stacked on one of the circuit board stacking assemblies 320 to one of the laminating modules 100 and stacking the circuit board with double-sided film pasting from the other laminating module 100 to the other circuit board stacking assembly 320.
Specifically, as shown in fig. 3, the two bonding modules 100 are a first bonding module 100a and a second bonding module 100b, and the two cover film feeding modules 200 are a first cover film feeding module 200a and a second cover film feeding module 200b, respectively. The first attaching module 100a and the second attaching module 100b are arranged side by side in the second horizontal direction Y; in a first horizontal direction X perpendicular to the second horizontal direction Y, two circuit board stacking assemblies 320 are respectively disposed on a first side of the first and second attachment modules 100a and 100b, and the first and second cover film feeding modules 200a and 200b are respectively disposed on a second side of the first and second attachment modules 100a and 100b, so that the apparatus is integrally formed into a compact and reasonable layout, and efficient cooperation is formed between the modules.
The lamination module 100 includes a lamination flipper platform 110, a flipper drive mechanism 120, a lamination head assembly 130, and a lamination drive mechanism 140. The adsorption surface of the attaching and overturning platform 110 is provided with negative pressure adsorption holes arranged in an array manner, so that the circuit board can be adsorbed and fixed; preferably, the bonding turning stages 110 of the two bonding modules 100 are connected to two independent negative pressure generating systems so as to control the adsorption state of the two bonding turning stages 110.
The inversion driving mechanism 120 drives the conformable inversion platform 110 to invert between a horizontal state as shown in fig. 4 and a vertical state as shown in fig. 5. When the attaching and inverting stage 110 is in a horizontal state, the head assembly 130 may attach the sucked sheet-like cover film to the circuit board. When the attachment turnover platforms 110 of the two attachment modules 100 are both turned to the vertical state, as shown in fig. 5 and 6, the two attachment turnover platforms 110 are close to or in contact with each other face to face, so that the circuit board can be transferred from the attachment turnover platform of the first attachment module to the attachment turnover platform of the second attachment module by adsorption. For example, when both the two attaching and flipping platforms 110 are in the vertical state, the negative pressure adsorption of the first attaching and flipping platform 110a is controlled to be closed, and the negative pressure adsorption of the second attaching and flipping platform 110b is controlled to be opened, so that the circuit board can be directly transferred from the first attaching and flipping platform 110a to the second attaching and flipping platform 110 b; otherwise, the circuit board may be transferred from the second bonding stage 110b to the first bonding stage 110a by suction.
In the invention, the two attaching and overturning platforms 110 are overturned between the horizontal state and the vertical state, so that the direct transfer and overturning of the circuit board between the two attaching modules 100 are realized, and an overturning mechanism is not required to be arranged outside an attaching mechanism as in the prior art, thereby not only improving the attaching efficiency, but also being beneficial to simplifying the equipment structure and reducing the equipment volume; further, the circuit board is directly transferred between the two attaching modules 100, so that the problem that impurities such as dust are easily adhered to the surface of the circuit board when a turnover mechanism is adopted in the prior art can be avoided, and the product quality is improved.
In an alternative embodiment, as shown in fig. 4 to 6, a connecting portion 401 is mounted on the frame 400, and the attaching and inverting platform 110 has a rotating shaft 111 rotatably connected to the connecting portion 401.

The mounting head assembly 130 comprises a mounting head 131 and a negative pressure control cylinder 132, wherein the mounting head 131 is provided with a negative pressure adsorption surface and a heating mechanism is arranged on the negative pressure adsorption surface, so that a sheet-shaped covering film can be attached to the circuit board in a heating flat pressing mode; the negative pressure control cylinder 132 is used to control the negative pressure suction of the mounting head 131 to be turned on or off.
Further, as shown in fig. 10, a detection camera 150 is disposed on the translation bracket 141, and the detection camera 150 may be a line scan camera. The inspection camera 150 may be used to detect the position of the circuit board, to achieve accurate alignment of the cover film and the circuit board, and may also be used to inspect the quality of the cover film, for example, to inspect bubbles that may appear after the cover film is attached. Here, the inspection camera 150 and the mounting head assembly 130 are preferably located at opposite sides of the translation bracket 141 in the first horizontal direction X so as not to affect the movement of the mounting head assembly 130.
Fig. 11 and 12 show the structure of the cover film feeding module 200 in the embodiment. Specifically, the cover film feeding module 200 includes an unwinding mechanism 210, a peeling mechanism 220, a cutting mechanism 230, a winding mechanism 240, and a cover film feeding platform 250; the unwinding mechanism 210 is configured to supply a film including a cover film and a release film, the cover film and the release film that are output from the unwinding mechanism 210 and bonded together are peeled off by the peeling mechanism 220, the peeled release film is wound by the winding mechanism 240, the cover film is cut to a predetermined length by the cutting mechanism 230, and the cut sheet-shaped cover film is adsorbed by the cover film feeding platform 250 under negative pressure.
In the above embodiment, the cutting mechanism 230 cuts the cover film peeled from the release film, which is beneficial to ensuring the cutting quality of the cover film, and the requirement on the motion control precision of the cutting mechanism 230 is relatively low. In contrast, in the prior art, the cover film is generally cut (half-cut) before the cover film and the release film are peeled off, the requirement for the movement accuracy of the cutting mechanism is extremely high, and the problems that the cover film is not completely cut or the release film is cut off easily occur.
In an alternative embodiment, the unwinding mechanism 210 includes an unwinding wheel 211 for mounting the film roll, a separator take-up wheel 218 for taking up the separator in the film roll, a first guide roller 212, a second guide roller 213, and a self-adjusting roller 214; a self-adjusting roller 214 is disposed between the first guide roller 212 and the second guide roller 213 on the film feeding path and can freely move up and down during unwinding.
Specifically, as shown in fig. 11, the two ends of the self-adjusting roller 214 are respectively provided with a lifting connection base 215 rotatably connected thereto, and the lifting connection base 215 is slidably disposed on the lifting guide rod 216. A gravity block may also be provided on the lifting connection seat 215 as needed. As shown in fig. 12, a sensor 217 is disposed at a position corresponding to a bottom dead center of the self-adjusting roller 214, and when the sensor 217 detects that the self-adjusting roller 214 moves to the bottom dead center, a discharging motor (not shown) connected to the discharging roller 214 stops operating to stop discharging the material from the discharging roller 211.
Because the self-adjusting roller 214 freely moves up and down in the unreeling process, the discharging wheel 211 keeps a stable discharging state while cutting the cover film, and the self-adjusting roller 214 moves downwards under the action of gravity along with the continuous discharging of the discharging wheel 211; when the film is fed to the cutting mechanism 230, since sufficient film is buffered between the first guide roller 212 and the second guide roller 213, the film can be fed to the cutting mechanism 230 at a feed speed faster than the linear speed of the outfeed roller 211 (at which time the self-adjusting roller 211 will move upward), thereby improving cutting efficiency.
In an alternative embodiment, as shown in fig. 13, the peeling mechanism 220 includes a peeling platform 221, and a front end of the peeling platform 221 forms a peeling blade 222 for peeling the cover film and the release film.

Preferably, the lower surface of the movable bead 223 may be provided with an elastic pad to increase friction between the movable bead 223 and the film and prevent an indentation from being formed on the cover film.
Further, the cover film feeding module 200 may further include a cover film clamping and transferring mechanism 260, and the cover film peeled from the release film is clamped by the cover film clamping and transferring mechanism 260 and conveyed forward along the first horizontal direction X, and then cut into a sheet shape by the cutting mechanism 230, and further sucked by the cover film feeding platform 250 under a negative pressure. Preferably, the cover film feeding platform 250 is configured to move along the first horizontal direction X to adjust the discharging position of the sheet-shaped cover film, so that the mounting head assembly 130 can suck the sheet-shaped cover film from the cover film feeding platform 250.
As shown in fig. 12, the cover film clamping and transferring mechanism 260 includes a cover film clamping assembly 261 and a movable base 262 connected to both ends of the cover film clamping assembly 261, wherein a clamping cylinder 263 is disposed on the movable base 262, and the clamping cylinder 263 is used for driving the cover film clamping assembly 261 to clamp the front end of the cover film. The movable base 262 is slidably disposed on the horizontal guide rod 264 and connected to a translation module, which may include a transmission belt, connected to the movable base 262 to drive the movable base 262 to slide on the horizontal guide rod 263, so that the cover film clamping assembly 261 moves along the first horizontal direction X to pull the cover film forward. When cutting, the movable pressing strip 223 presses the film onto the peeling platform 221, and the cover film clamping assembly 261 tensions the cover film, so that the flatness of the cover film can be ensured.
In other embodiments of the present invention, the cover film feeding module may not have a cutting structure, but may directly use the cut cover film, for example, a roll of cover film that has been half-cut, and the typical structure of the cover film feeding module may refer to the film feeding booms commonly used in the prior art.
In an alternative embodiment, as shown in fig. 11, the winding mechanism 240 includes a material receiving wheel 241, a third guide roller 242, and a fourth guide roller 243, and the release film peeled from the cover film is wound by the material receiving wheel 241 after passing around the third guide roller 242 and the fourth guide roller 243.
