as shown in fig. 1, 2 and 3, this embodiment provides an automatic film sticking apparatus which can peel off the sticking film M1 on the roll film M0 from the base film M2 and stick it to the surface of the work G. The automatic film sticking device comprises a rack mechanism 100, a detection mechanism 700, a prepressing mechanism 300, a turntable mechanism 200, a film suction mechanism 400, a peeling mechanism 500 and a film pressing mechanism 600, wherein the detection mechanism 700, the prepressing mechanism 300, the turntable mechanism 200, the film suction mechanism 400, the peeling mechanism 500 and the film pressing mechanism 600 are directly or indirectly arranged on the rack mechanism 100, and the rack mechanism 100 comprises a shell for covering other mechanisms. The automatic film pasting device has the following specific structure:

as shown in fig. 2 and 3, in the present embodiment, the turntable mechanism 200 includes a rotatable circular turntable, and the turntable is provided with a plurality of tool slots for receiving the workpieces G, and the turntable can rotate to switch the work stations of the workpieces G.

As shown in fig. 3, in the embodiment, the detection mechanism 700 is disposed at a position corresponding to the turntable, and the detection mechanism 700 can detect whether the workpiece G is already placed on the turntable, and when the workpiece G is missed on the tool slot, a warning sound is generated to prevent failure of subsequent film pasting.

As shown in fig. 2 and 3, in the present embodiment, the prepressing mechanism 300 includes a pressing base capable of moving up and down, and when the workpiece G is switched to a position below the pressing base by rotation, the pressing base can move down to press the workpiece G against the work groove of the turntable.

As shown in fig. 5 and 6, in the present embodiment, the peeling mechanism 500 includes a pressing assembly 510, a peeling base 530, a first movable roller 540, a second movable roller 550, a film feeding motor 580, and a peeling driving member 520. The film roll M0 first passes through the hold-down assembly 510 and extends forward against the surface of the stripper shoe 530, and then sequentially passes around the first movable roller 540, the second movable roller 550, and the film feed motor 580. Wherein, the pressing assembly 510 can press the rolled film M0, so that the film feeding motor 580 can not pull the rolled film M0 any more, and the rolled film M0 is tensioned. The peeling base 530 has a wedge-shaped geometry, and the rolled film M0 extends forward along the upper surface of the peeling base 530, winds around the first movable roller 540 obliquely downward from the wedge end of the peeling base 530, winds around the second movable roller 550 horizontally, and finally winds around the film feeding motor 580. Wherein the peeling driver 520 can drive the peeling seat 530 and the first movable roller 540 to move back and forth together.

In addition, as shown in fig. 6 and 7, in the present embodiment, the first movable roller 540 and the second movable roller 550 are both located below the peeling base 530, and the rolled film M0 located between the first movable roller 540 and the second movable roller 550 is parallel to the rolled film M0 located between the pressing assembly 510 and the peeling base 530. When the peeling seat 530 is located at the frontmost end, after the film sticking mechanism 400 sucks the adhesive film M1 from the rolled film M0 on the peeling seat 530, the peeling driving member 520 drives the peeling seat 530 and the first movable roller 540 to move backward together, so that the adhesive film M1 and the base film M2 are separated to complete the peeling operation of the adhesive film M1. Note that when the peeling base 530 is positioned at the foremost end, the length of the rolled film M0 from the pressing member 510 to the second movable roller 550 is L1+ L2+ L3+ L4. When the peeling seat 530 is positioned at the rearmost end, the length of the rolled film M0 from the pressing assembly 510 to the second movable roller 550 at this time is L1+ L2 '+ L3' + L4. Since L2/L2 'and the peeling base 530 is horizontally moved, L3/L3', L2, L2 ', L3, and L3' form a parallelogram, L2 is L2 ', and L3 is L3'. Therefore, during the forward and backward movement of the peeling seat 530, the length of the rolled film M0 from the pressing assembly 510 to the second movable roller 550 does not change and the rolled film M0 from the pressing assembly 510 to the peeling seat 530 does not move while the tension of the rolled film M0 is kept constant. Therefore, in the automatic film sticking device of the embodiment, when the peeling seat 530 moves back and forth to perform the peeling operation and finally returns to the forefront end, the position between the sticking film M1 and the film suction mechanism 400 is not changed, and the accuracy of the sticking film M1 is ensured.

The suction plate assembly 450 is moved to a position above the peeling base 530 and corresponding to the film M1 in advance, the second pressing driver 420 drives the suction plate assembly 450 to move downward and suck the film M1, and when the peeling base 530 moves backward and finishes peeling the film M1 and the bottom film M2, the first pressing driver 410 and the transferring driver 440 finish the film M1 action on the workpiece G. It should be noted that the suction plate assembly 450 includes a suction plate 451 and an elastic member 452, when the suction plate 451 presses against the adhesive film M1, the suction plate 451 is forced to move upward and compress the elastic member 452, in this embodiment, the elastic member 452 is a spring. The suction plate assembly 450 with the structure can ensure that the suction plate 451 has up-and-down buffering, and prevent the suction plate 451 from pressing against the peeling seat 530 to influence the backward movement of the peeling seat 530 due to overlarge pressure. In addition, the suction plate assembly 450 of the present embodiment further includes a detecting member for detecting the vacuum pressure value, and when the vacuum level is not high, an alarm sound is generated to indicate that the adhesive film M1 is not in proper position.

As shown in fig. 2 and 3, in the present embodiment, the lamination mechanism 600 includes a lamination base movable up and down, and when the workpiece G passes through the film suction mechanism 400 and is attached with the film M1, and then is rotationally switched to a position below the lamination base, the lamination base is movable down to perform final lamination on the film M1 and the workpiece G.

As shown in fig. 5 and 6, in the present embodiment, the peeling mechanism 500 further includes a weight 590, a pair of sensors 570, and a wind-up roller 5a0 to wind up the roll film M0. The weight 590 can drive the redundant bottom film M2 to move downward, and the pair of sensors 570 are respectively located above and below the weight 590. When the lower sensor 570 detects the weight 590, the wind-up roller 5a0 starts to rotate the wind-up bottom film M2, so that the weight 590 moves upward; when the upper sensor 570 detects the weight 590, the wind-up roller 5a0 stops working. Through the structure, the automatic film sticking device of the embodiment can realize the automatic rolling of the bottom film M2.

As shown in FIG. 4, in the present embodiment, the film suction mechanism 400 includes a pair of suction plate assemblies 450, and the film suction mechanism 400 further includes a pitch-variable driving member 430, wherein the pitch-variable driving member 430 is used for adjusting the pitch of the pair of suction plate assemblies 450. In operation, when the pair of suction plate assemblies 450 suck the peeled pair of films M1, the pitch drive 430 can change the distance between the pair of films M1 to match the work groove on the turntable. Through the structure, the automatic film sticking device of the embodiment can adapt to products and sticking films M1 of passing specifications, and the details are not repeated.

In addition, in the present embodiment, the first push-down driver 410, the second push-down driver 420, the transfer driver 440, and the peeling driver 520 are all cylinder type drivers. Of course, in another embodiment, the first pressing driver 410, the second pressing driver 420, the transferring driver 440, and the peeling driver 520 may be other devices capable of performing linear reciprocating motion in the prior art, and will not be described herein again.

Through the above scheme of the embodiment, the automatic film sticking device of the embodiment can automatically stick the film sticking M1 on the roll film M0 to the workpiece G, and greatly improves the film sticking efficiency and quality. Meanwhile, in the process of peeling the adhesive film M1 by the peeling mechanism 500, the adhesive film M1 does not move, so that the position accuracy between the film suction mechanism 400 and the adhesive film M1 is ensured, and the adhesive film quality is further improved.
