Description

Technical Field

[0001] The present invention relates to the field of product film pasting, and in particular to a film pasting device and a film pasting method. Background Art

[0002] During the production process of some products, it is necessary to stick an adhesive film on the product. At this time, a film sticking device is needed. The traditional film sticking device includes a carrier conveyor line, which is used to transport the carrier to the film sticking station. At the film sticking station, the film sticking head will absorb the prepared adhesive film and transfer it to the product on the carrier, so that the adhesive film and the product are bonded. There are many ways to supply adhesive film, but traditional adhesive film is generally supplied together with the base film. At this time, a mechanism is needed to separate the base film from the adhesive film, that is, a film tearing mechanism is needed. The traditional film tearing mechanism removes the base film through the cooperation of easy-tear stickers and clamps, but this film tearing method is inefficient and not efficient enough. And if there are multiple adhesive films arrayed on a base film, in this case, it is not convenient to separate the base film from each adhesive film using the traditional film tearing mechanism. Summary of the invention

[0003] Based on this, a film sticking device is provided. When there are multiple adhesive films on a base film, it is convenient to separate the base film from the adhesive film, and the film tearing efficiency is high.

[0023] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given with reference to the accompanying drawings.

[0024] Such as Figure 1As shown, an embodiment of the present application provides a film pasting device, which includes a frame 600, on which are disposed: a film supply mechanism 100, a film tearing mechanism 200, an adsorption transfer mechanism 400, and a carrier conveying mechanism 500. Figures 2 to 4 As shown, the film supply mechanism 100 is arranged on the upstream side of the film tearing mechanism 200, and the film supply mechanism 100 is used to squeeze a single film to the film tearing mechanism 200, and the film includes a base film 710 and a plurality of adhesive films 720 arranged in an array and arranged on the base film 710, and the film tearing mechanism 200 includes a pressing block 210, and the pressing block 210 is connected to the first lifting assembly below, and a drag plate 220 is arranged on one side of the pressing block 210, and a strip hole 221 for the film to pass through and a clearance through hole 222 located below the strip hole 221 are provided on the drag plate 220, The dragging plate 220 is connected to the second lifting assembly 280, and a driven roller assembly 230 and an active roller 240 assembly are respectively provided on both sides of the dragging plate 220, and the active roller 240 assembly includes an active roller 240 and a driving assembly 250 connected to the active roller 240, and the active roller 240 assembly is connected to a bracket 260, and the bracket 260 is connected to the linear driving assembly 250, and a peeling platform 290 is provided on the top of the bracket 260, and a first sensor 270 is provided on the bracket 260, and the first sensor 270 is used to detect the position of the film.

[0025] When the above-mentioned device of the present application is working, the film supply mechanism 100 supplies the film to the film tearing mechanism 200, and the film includes a base film 710 and a plurality of adhesive films 720 arranged in an array on the base film 710. For example, N rows of adhesive films 720 are arranged on the base film 710, and the number of adhesive films 720 in each row is 4. When the first sensor 270 detects that the front end of the base film 710 of a film is transported to the strip hole 221 of the drag plate 220, the pressing block 210 descends, and the drag plate 220 pulls the front end of the base film 710 downward to between the driven roller assembly 230 and the active roller 240 assembly. Then, the active roller 240 assembly moves toward the driven roller assembly 230, and clamps the front end of the base film 710 by means of the above-mentioned clearance through hole 222. Then, the active roller 240 assembly rotates, so that the adhesive film 720 is separated from the base film 710, and the four adhesive films 720 move to the peeling platform 290. Then, the adhesive film 720 is adsorbed and transferred to the product on the carrier 800 on the carrier conveying mechanism 500 by the adsorption transfer mechanism 400. As the bottom film 710 is continuously conveyed downward, the subsequent adhesive film 720 on the bottom film 710 is continuously conveyed to the peeling platform 290.

[0026] In one embodiment, if Figure 2As shown in the figure, the mold feeding mechanism includes a first belt conveying assembly 160a and a second belt conveying assembly 160b arranged in sequence. The conveying speed of the first belt conveying assembly 160a is less than that of the second belt conveying assembly 160b. A material distributing plate 110 is inclinedly arranged above the second belt conveying assembly 160b. The front end of the material distributing plate 110 is lower than the rear end of the material distributing plate 110. The rear end of the material distributing plate 110 is connected to a support member 120, and the support member is connected to a cross beam 610 arranged on the frame 600. A pressing roller 140 is arranged on the plate body of the material distributing plate 110. The pressing roller 140 is arranged on a roller frame 130 arranged obliquely. A strip-shaped hole 130a is arranged on the roller frame 130, and a support shaft 150a is arranged in the strip-shaped hole 130a. The rear end of the roller frame is supported by a tail end positioning member 150b, and the tail end positioning member 150b and the support shaft 150a are installed on the frame 600.

[0027] Specifically, the cooperation between the low end of the material distributing plate 110 and the second belt conveying assembly 160b enables one film to pass through, that is, only one film is conveyed to the film tearing mechanism 200 each time. The pressing roller 140 is used to apply a certain pressure to the material distributing plate 110, and this pressure is adjustable. The specific adjustment method is to adjust the position of the support shaft 150a relative to the strip-shaped hole 130a on the roller frame 130.

[0028] Specifically, the above-mentioned first belt conveying assembly 160a can be driven by a larger synchronous pulley 170a, and the second belt conveying assembly 160b can be driven by a smaller synchronous pulley 170b. A motor is arranged on the first belt conveying assembly 160a, and the motor is connected to the larger synchronous pulley 170a. The smaller synchronous pulley 170b is connected to the larger synchronous pulley 170a through a synchronous belt. In this way, the conveying speed of the first belt conveying assembly 160a can be less than that of the second belt conveying assembly 160b.

[0029] In one embodiment, as Figure 1 and Figure 6 shown, a first vision component 300 is arranged between the adsorption transfer mechanism 400 and the peeling platform 290. The adsorption transfer mechanism 400 includes a two-dimensional movement module. A cam-type lifting component 430 is arranged on the two-dimensional movement module. A rotating component 440 is arranged on the cam-type lifting component 430. A vacuum suction head 450 is arranged on the rotating component 440.

[0030] Furthermore, a second vision component 460 is arranged on one side of the cam-type lifting component 430.

[0031] Specifically, the above two-dimensional movement module may include an X-axis movement module 410 and a Y-axis movement module 420. The above cam-type lifting assembly 430 is an existing lifting assembly. The above rotation assembly 440 may be a mechanism such as a stepper motor.

[0032] Specifically, after the film 720 is adsorbed by the vacuum suction head 450, it is first detected at the first vision component 300 whether the film 720 is qualified. If it is qualified, the film 720 is conveyed to the product at the carrier. Then, the specific position of the product is identified by the second vision component 460. Finally, the film 720 is attached to the product. The above first vision component 300 and second vision component 460 can be implemented using existing related vision components.

[0033] In one embodiment, as Figure 1 and Figure 7 shown, the carrier conveying mechanism 500 includes two conveying rail assemblies, namely a first conveying rail assembly 510 and a second conveying rail assembly 520. The first conveying rail assembly 510 and the second conveying rail assembly 520 are both arranged on the spacing adjustment assembly 570. The spacing adjustment assembly 570 is used to adjust the spacing between the first conveying rail assembly 510 and the second conveying rail assembly 520. A first blocking assembly 530 and a first carrier positioning assembly are arranged at the first conveying rail assembly 510. A second blocking assembly and a second carrier positioning assembly are arranged at the second conveying rail assembly 520.

[0034] Specifically, the above conveying rail assembly includes a conveying track and a synchronous belt conveying mechanism installed on the conveying track. The above spacing adjustment assembly 570 includes two spaced adjustment components. Each adjustment component includes a slide rail assembly and a lead screw mechanism. The conveying rail assembly is installed on the slide rail assembly and connected to the lead screw mechanism. By synchronously adjusting the two lead screw mechanisms, the distance between the first conveying rail assembly 510 and the second conveying rail assembly 520 can be adjusted. The above first blocking assembly 530 and second blocking assembly can both be composed of a blocking member and a cylinder for driving the blocking member to lift. The above first carrier positioning assembly and second carrier positioning assembly can be set according to the type of the carrier. For example, it may include a lifting cylinder 540, a lifting plate 550 connected to the lifting cylinder 540, and a baffle 560 located above the lifting plate 550. The carrier is lifted by the lifting plate 550 and abutted against the baffle 560 above, so that the carrier can be positioned.

[0035] An embodiment of the present application further provides a film pasting method, including the film pasting device. A film is supplied to the film tearing mechanism 200 by the film supply mechanism 100. The film includes a base film 710 and a plurality of adhesive films 720 arranged in an array on the base film 710. When the first sensor 270 detects that the front end of the base film 710 of a film is transported to the strip hole 221 of the dragging plate 220, the pressing block 210 descends, and the dragging plate 220 drags the front end of the base film 710 downward to between the driven roller assembly 230 and the driving roller 240 assembly. The driving roller 240 assembly moves toward the driven roller assembly 230, and then clamps the front end of the base film 710. The driving roller 240 assembly rotates, so that the adhesive film 720 is separated from the base film 710, and the adhesive film 720 moves to the peeling platform 290.

[0036] The above embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
