The film suction device 21 at least comprises three suction surfaces 210, at least two suction surfaces 210 of the three suction surfaces 210 are adjacent, an included angle A is formed between the two adjacent suction surfaces 210, and one suction surface 210 is parallel to the film pasting platform 32. When the film sucking device 21 rotates to the connection position of two adjacent sucking surfaces 210 towards the film cutting mechanism 31, one sucking surface 210 faces the film pasting platform 32, the film pasting platform 32 is close to the sucking surface 210, so that the product 300 to be pasted is aligned with the film 201, and the sucking surface 210 releases the film 201, so that the film 201 is pasted with the product 300 to be pasted.

The film strip 200 is adsorbed by at least three adsorption surfaces 210, so that the film strip 200 can form a flat state on two adsorption surfaces 210, and the film 201 can be directly attached to the product 300 to be attached by using the third adsorption surface 210. The film strip 200 is cut by the film cutting mechanism 31, so that the continuous film strip 200 is cut into films 201 which are matched with the size of the product 300 to be laminated, and the film strip 200 is cut while being cut, the film laminating platform 32 is used for approaching one of the adsorption surfaces 210, so that the surface of the product 300 to be laminated faces the films 201 on the adsorption surface 210 correspondingly, the films 201 and the surface of the product 300 to be laminated are aligned accurately, for example, the films 201 vertically correspond to the product 300 to be laminated, and the adsorption surface 210 can release the films 201 so that the films 201 leave the adsorption surfaces 210. After the lamination is completed, the film sucking device 21 can continue to rotate, so that the other sucking surface 210 faces the next product 300 to be laminated and is used for laminating, and the joint of the two sucking surfaces 210 faces the film cutting mechanism 31 again, and the film cutting mechanism 31 is used for carrying out the next film cutting operation. Thus, the cutting process and the film pasting process of the film tape 200 can be performed simultaneously and are not interfered with each other, and the film pasting efficiency is improved. By adopting the scheme of the application, on one hand, the film can be pasted without adopting a rolling way of a roller, the film strip 200 on the adsorption surface 210 is cut off by the film cutting mechanism 31 to form the film 201, and the surface of the product 300 to be pasted is directly adhered to the film 201 on the adsorption surface 210, so that the problems of film pasting deformation or dislocation and the like caused by the deformation of the roller are avoided, and the film pasting effect and the product yield are improved. On the other hand, the film 201 is adsorbed by more than two adsorption surfaces 210, so that the film cutting operation of the film cutting mechanism 31 and the film pasting operation of the film pasting platform 32 can be simultaneously performed, and the film pasting efficiency is improved.

Illustratively, the included angle a satisfies 0 ° < a <180 °, i.e., the included angle a may be 30 °, 45 °, 60 °, 90 °, 100 °, 150 °, etc. An example of the angle a of 90 ° will be described below.

In some embodiments, the film sucking device 21 includes a rotating device 215 and four sucking surfaces 210, the four sucking surfaces 210 are disposed around the periphery of the rotating device 215 at equal intervals, and the rotating device 215 is used to drive the sucking surfaces 210 to rotate, so that when the connection between two adjacent sucking surfaces 210 faces the film cutting mechanism 31, one of the remaining sucking surfaces 210 faces the film pasting platform 32.

The four adsorption surfaces 210 can further facilitate the simultaneous film cutting operation and film sticking operation. When the film cutting mechanism 31 performs film cutting operation on the joint of two adjacent adsorption surfaces 210, the film pasting platform 32 can perform film pasting operation on any one of the other two adsorption surfaces 210 towards the film pasting platform 32, so that on one hand, enough space can be provided for the film pasting platform 32 to move and approach the film 201, and the problems that the film pasting platform 32 interferes with the film cutting mechanism 31 are avoided.

Preferably, the four suction surfaces 210 are disposed equidistantly along the outer circumference of the rotating device 215, that is, the four suction surfaces 210 are combined to form a regular quadrangular prism-shaped structure along the outer circumference of the rotating device 215, so that each suction surface 210 has the same size in the width direction (x direction as shown in fig. 3), and uniformity of the size of the film strip 200 after being cut into the film sheet 201 can be ensured to match the specification of the product 300 to be laminated. Meanwhile, the rotation angle of the rotation device 215 is the same every time, that is, the rotation device 215 rotates 90 ° every time, so that when the joint of two adjacent adsorption surfaces 210 is aligned with the film cutting mechanism 31, one of the other two adsorption surfaces 210 is aligned with the film pasting platform 32, the accuracy of film cutting and film pasting processes is ensured, and the processing yield of the whole film pasting process is improved.

Illustratively, the film cutting mechanism 31 is used to cut the film strip 200 into film pieces 201 of the same size, and the film pieces 201 are of the same size as the product 300 to be film-coated. In this way, after each film cutting operation, the film cutting mechanism 31 always obtains the film 201 with the same size, and the film 201 can meet the accuracy requirement of film pasting when being used for pasting the product 300 to be film-pasted. In one example, the size of the film 201 after film cutting is the same as the size of the product 300 to be film-coated, although in other examples, the size of the film 201 after film cutting may be larger or smaller than the product 300 to be film-coated according to the processing requirements, so as to meet different design requirements. The film 201 of a corresponding size is obtained by changing the film suction device 21 having a different suction surface size or adjusting the cutting position of the film cutting mechanism 31.

In this way, the rotation device 215 can enable the adsorption surfaces 210 of any two adjacent film sucking belts 200 to rotate to the position of the film cutting mechanism 31 for film cutting respectively through continuous rotation, and further rotate to the position of the first working position 211 for film pasting, so that continuous automatic film pasting operation is completed.

By utilizing the approaching or separating action of the movable table 321 relative to the first working position 211, the contact and adhesion between the product 300 to be laminated and the film 201 can be realized, the product to be laminated is obtained after the contact and adhesion, and when the movable table 321 is far away from the first working position 211 and the film sucking device 21 continues to rotate, the film sucking device 210 sucks the film strip 200 again to be laminated next time when the next sucking surface 210 reaches the first working position 211.

In some embodiments, the suction device 21 further comprises a vacuum pump for sucking the film sheet 201 by the suction surface 210 located at the second working position 212 and the third working position 213, and for breaking the vacuum when the film attaching platform 32 approaches the suction surface 210 located at the first working position 211, so that the suction surface 210 releases the film sheet 201. The vacuum suction and the vacuum breaking of the vacuum pump are utilized, so that the suction and the release of the suction surface 210 are switched. When the vacuum pump breaks vacuum, the adsorption surface 210 releases the adsorption function on the membrane 201, and the membrane 201 can be separated from the adsorption surface 210 under the action of self gravity and vacuum break, and the combination with the product 300 to be pasted can be completed.

Illustratively, the tensioning roller shaft assembly 22 may include one or more tensioning roller shafts 221, and the tensioning roller shafts 221 may be flexibly arranged according to the feeding position and feeding direction of the film strip 200, so that the film strip 200 can smoothly enter the film suction device 21, and the film strip 200 can be tensioned under the interaction with the film suction device 21.

In some embodiments, the film cutting mechanism 31 includes a cutter 311 and a second driving member 312, where the cutter 311 is disposed corresponding to a connection between two adjacent suction surfaces 210, and the second driving member 312 is used to drive the cutter 311 to move along a width direction (x direction in fig. 3) of the film strip 200 so as to cut the film strip 200. The cutter 311 is used for cutting along the joint of the two adsorption surfaces 210, so that the size of the cut film strip 200 is adapted to the size of the product 300 to be adhered, and the cutter 311 can make the cut smoother along the joint due to the fact that the joint of the two adsorption surfaces 210 is in a straight line state, and the film cutting effect is improved.

Illustratively, the cutters 311 may be disposed along an angular bisector of the angle a between two adjacent suction surfaces 210. In this way, the cutter 311 can better cut off the film strip 200, so that the film strip 200 can be broken at the edge position formed by the mutual connection of the two adsorption surfaces 210, thereby ensuring that the sizes of the films 201 on the surfaces of the two adjacent adsorption surfaces 210 are consistent, and improving the film cutting process and the film pasting precision.

In some embodiments, the conveying mechanism 10 includes a conveying belt 11 and a third driving member 12, the third driving member 12 is used to drive the conveying belt 11 to move, and the conveying belt 11 is used to carry the product 300 to be coated or the coated product. The product 300 to be laminated can be conveyed to the laminating platform 32 by using the conveying belt 11, the product 300 to be laminated is moved to be close to the adsorption surface 210 by the laminating platform 32 for lamination, and the product after lamination can be transferred to the conveying belt 11 by using the laminating platform 32, so that the product is conveyed away by using the conveying belt 11. In other examples, the conveyor belt 11 may be replaced by a plurality of rollers arranged in sequence.

In some embodiments, when the film deposition platform 32 is away from the suction surface 210 at the first work station 211, the film deposition platform 32 moves to be flush with the surface of the conveyor belt 11. This helps to move the product 300 to be laminated from the conveyor belt 11 to the lamination stage 32, or from the lamination stage 32 to the conveyor belt 11, and can ensure the stability of the product 300 to be laminated during the movement, avoiding collision or deformation of the product 300 to be laminated.
