[0040] Reference below Figures 1 to 12 The film sticking device of the present application is described in detail.

[0041] refer to Figure 1 The film laminating device according to the embodiment of the present invention includes a lower glue film supply module 10 , a film material conveying module 200 , a film material lifting module 300 and an upper glue film supply module 400 .

[0042] For example, Figure 1 and Figure 4As shown, the lower film supply module 10 includes a jig transfer assembly 100 and a lower film feeding assembly. The jig transfer assembly 100 is provided with a laminating station 101 and a feeding station 102. The feeding station 102 is located on the left side of the laminating station 101. The jig transfer assembly 100 is used to drive the jig 130 to circulate between the laminating station 101 and the feeding station 102. The lower film feeding assembly is arranged on one side of the jig transfer assembly 100 and is used to feed the lower film to the feeding station 102. The jig 130 in the laminating station 102 is on the jig 130; the film material conveying module 200 is arranged on the front side of the jig transfer component 100, and is used to drive the film material to move from the back to the front, so that the film material can pass through the laminating station 101; the film material lifting module 300 is arranged on the rear side of the jig transfer component 100, and is used to drive the film material to do lifting and lowering movement; the adhesive film supply module 400 is arranged on the right side of the jig transfer component 100, and is used to laminate the adhesive film on the upper surface of the film material at the laminating station 101.

[0043] Furthermore, when the film laminating device of the present application is working, the film material conveying module 200 can drive the film material to move from the back to the front, so that the film material moves to the laminating station 101; the lower film loading component can load the lower film onto the jig 130 of the loading station 102; then, under the drive of the jig transfer component 100, the jig 130 loaded with the lower film moves from the loading station 102 to the laminating station 101, and is located directly below the film material; then, the film material lifting module 300 can drive the film material to move downward, so that the lower surface of the film material can be laminated to the lower film on the jig 130; then, the upper film supply module 400 can laminate the upper film to the upper surface of the film material at the laminating station 101; and then the laminating of the upper film and the lower film on the upper surface and the lower surface of the film material are respectively completed.

[0044] It can be seen from the above content that the film laminating device of the present application can complete the laminating of the upper adhesive film and the lower adhesive film on the upper surface and the lower surface of the film material respectively at one time, saving time and labor.

[0045] In some embodiments of the present invention, reference Figure 2 The film material lifting module 300 includes a first driver 310 and a lifting seat 320. The lifting seat 320 is provided with a first limiting surface 321 and a second limiting surface 322 distributed in the vertical direction. The first limiting surface 321 is located above the second limiting surface 322. A material passage allowing the film material to pass through is formed between the first limiting surface 321 and the second limiting surface 322. The first driver 310 is connected to the lifting seat 320 and is used to drive the lifting seat 320 to perform lifting movements.

[0046] It can be understood that when the film material lifting module 300 needs to push the film material to move downward, the first driver 310 can drive the lifting seat 320 to move downward, so that the first limiting surface 321 pushes the film material to move downward; when the film material lifting module 300 needs to push the film material to move upward, the first driver 310 can drive the lifting seat 320 to move upward, so that the second limiting surface 322 pushes the film material to move upward.

[0047] In a further embodiment of the present invention, reference Figure 3 A first guide groove 323 extending forward and backward is provided on the lifting seat 320. The two groove edges at the upper end of the first guide groove 323 extend toward the middle of the first guide groove 323 to form two abutment protrusions 324. The lower end surface of the abutment protrusion 324 forms a first limiting surface 321, and the bottom of the first guide groove 323 forms a second limiting surface 322.

[0048] In some embodiments of the present invention, the jig transfer assembly 100 includes a second driver 110, a rotating table 120 and a jig 130. The jig 130 is disposed on the rotating table 120. The second driver 110 is connected to the rotating table 120 and is used to drive the rotating table 120 to rotate so that the jig 130 circulates through the loading station 102 and the bonding station 101.

[0049] For example, Figure 4 and Figure 5 As shown, the jig transfer assembly 100 includes a second driver 110, a rotating table 120 and two jigs 130. The second driver 110 is connected to the rotating table 120 and is used to drive the rotating table 120 to rotate around a vertical axis. The two jigs 130 are symmetrically arranged on the rotating table 120 about the rotation axis of the rotating table 120, and when one of the jigs 130 is located at the loading station 102, the other jig 130 is just located at the bonding station 101.

[0050] It is understandable that, driven by the second driver 110 , the rotating table 120 can rotate around the vertical axis so that the jig 130 can cyclically move between the loading station 102 and the bonding station 101 .

[0051] It can be understood that by setting two jigs 130 on the rotating table 120, when one of the jigs 130 is located at the laminating station 101, the other jig 130 is just located at the loading station 102 to wait for the loading of the lower film loading assembly, thereby improving the working efficiency of the film laminating device of this embodiment.

[0052] In some embodiments of the present invention, reference Figure 6The jig 130 includes a jig body 131 and a floating plate 132. The floating plate 132 is floatably disposed at the lower end of the jig body 131 in the vertical direction. The jig body 131 is provided with an insertion hole that penetrates the jig body 131 in the vertical direction. The floating plate 132 is provided with a positioning rod 133 for positioning the lower adhesive film. The positioning rod 133 is slidably penetrated in the insertion hole. The jig transfer assembly 100 also includes a third driver 140. The third driver 140 is disposed at the laminating station 101 and is used to drive the floating plate 132 at the laminating station 101 to perform a lifting movement so that the positioning rod 133 extends out of or retracts into the insertion hole.

[0053] It can be understood that before the film material lifting module 300 drives the film material to move downward so that the lower surface of the film material approaches and adheres to the lower film on the fixture 130, the third driver 140 can drive the floating plate 132 to move downward so that the positioning rod 133 can be retracted downward into the insertion hole to avoid the film material.

[0054] It should be noted that since the floating plate 132 needs to follow the jig 130 to circulate between the laminating station 101 and the loading station 102, and the third driver 140 is arranged at the laminating station 101 and cannot move with the jig 130, when the jig 130 moves to the laminating station 101, the driving end of the third driver 140 needs to be connected to the floating plate 132, and when the jig 130 leaves the laminating station 101, the driving end of the third driver 140 needs to be disconnected from the floating plate 132.

[0055] Based on the above problems, in some embodiments of the present invention, reference Figure 5 and Figure 6 The third driver 140 includes a cylinder 141 and a first hook 142 , and the floating plate 132 is provided with a second hook 132 a .

[0056] Furthermore, when the rotating table 120 drives the jig 130 to rotate forward to enter the bonding station 101, the second hook 132a is engaged with the first hook 142. At this time, the cylinder 141 can smoothly drive the floating plate 132 to move downward through the first hook 142. When the rotating table 120 drives the jig 130 to rotate reversely to leave the bonding station 101, the second hook 132a is disengaged from the first hook 142.

[0057] In some embodiments of the present invention, reference Figure 5 and Figure 6 The fixture 130 also includes a mounting plate 134, which is connected to the lower end surface of the rotating table 120, the fixture body 131 is connected to the upper end surface of the rotating table 120, and the floating plate 132 is arranged between the fixture body 131 and the mounting plate 134, and the floating plate 132 is connected to the upper end of the mounting plate 134 through a spring 135.

[0058] Furthermore, under the elastic force of the spring 135, the floating plate 132 can abut against the jig body 131 upward, so that the positioning rod 133 on the floating plate 132 can extend out of the insertion hole. At this time, the positioning rod 133 can smoothly position the lower adhesive film on the jig 130; when the jig 130 is located at the bonding station 101, the first hook 142 is engaged with the second hook 132a, and the cylinder 141 can drive the second hook 132a to move downward through the first hook 142, so that the second hook 132a can drive the floating plate 132 to overcome the elastic force of the spring 135 to move downward. At this time, the insertion rod retracts downward into the insertion hole to avoid the film material.

[0059] In order to make the upper glue film and the lower glue film more firmly attached to the film material, in some embodiments of the present invention, reference Figure 1 The film laminating device also includes a pressure-maintaining module 500, which is arranged on a preset path of the film material and is used to maintain the pressure of the upper glue film and the lower glue film on the film material.

[0060] It can be understood that by setting up the pressure-holding module 500, after the upper adhesive film and the lower adhesive film are attached to the film material, the pressure-holding module 500 can maintain the pressure on the upper adhesive film and the lower adhesive film on the film material, so that the upper adhesive film and the lower adhesive film can be more firmly attached to the film material, thereby reducing the probability of the upper adhesive film or the lower adhesive film automatically falling off from the film material.

[0061] In some embodiments of the present invention, the pressure maintaining module 500 includes a pressure maintaining block 510 and a driving assembly 520 . The driving assembly 520 is connected to the pressure maintaining block 510 , and the driving assembly 520 can drive the pressure maintaining block 510 to move closer to or away from the fixture 130 on the bonding station 101 .

[0062] For example, Figure 7 As shown, the driving assembly 520 includes a horizontal driving structure and a vertical driving structure. The horizontal driving structure includes a frame 521 and a fifth driver 522. The frame 521 is provided with a guide rail 521a extending left and right. The vertical driving structure includes a pressure seat 523 and a sixth driver 524. The pressure seat 523 is slidably disposed on the guide rail 521a and is connected to the output end of the fifth driver 522. The sixth driver 524 is disposed on the pressure seat 523 and is connected to the pressure block.

[0063] Furthermore, driven by the fifth driver 522, the pressure seat 523 can slide left and right along the guide rail 521a, so that the pressure block moves to the bonding station 101 and is located directly above the film material in the bonding station 101. Driven by the sixth driver 524, the pressure block can move up and down, so that the pressure block is close to or away from the jig 130 in the bonding station 101, so that the pressure block can cooperate with the jig 130 to complete the pressure maintenance of the upper and lower films on the surface of the film material.

[0064] It should be noted that an upper protective film is laminated on the upper adhesive film, and a lower protective film is laminated on the lower adhesive film. After the upper adhesive film and the lower adhesive film are respectively laminated to the film material, the upper adhesive film and the lower adhesive film need to be torn off respectively to remove the upper protective film on the upper adhesive film and to remove the lower protective film on the lower adhesive film.

[0065] Based on the above reasons, in some embodiments of the present invention, reference Figure 1 and Figure 8 The film-sticking device also includes a film-tearing module 600, which is arranged on a preset path. The film-tearing module 600 includes a first film-tearing component 610 and a second film-tearing component 620. The first film-tearing component 610 is located below the film material and is used to tear off the lower adhesive film on the film material to remove the lower protective film on the lower surface of the lower adhesive film. The second film-tearing component 620 is arranged above the film material and is used to tear off the upper adhesive film on the film material to remove the upper protective film on the upper surface of the upper adhesive film.

[0066] In some embodiments of the present invention, the first film tearing assembly 610 includes a fourth driver 611, a first slide rail 612 and a first adsorption structure 613. The first adsorption structure 613 is slidably disposed on the first slide rail 612 and is used to adsorb the lower protective film on the lower adhesive film. The extension direction of the first slide rail 612 is spaced apart from the extension direction of the preset path by a certain angle. The fourth driver 611 is connected to the first adsorption structure 613 and is used to drive the first adsorption structure 613 to slide along the first slide rail 612.

[0067] For example, Figure 8 and Fig. 9 As shown, the extension direction of the preset path is the front-to-back direction, the first slide rail 612 is arranged below the preset path and extends along the front-upward direction, the first adsorption structure 613 is arranged on the first slide rail 612 and is connected to the output end of the fourth driver 611. Driven by the fourth driver 611, the first adsorption structure 613 slides along the first slide rail 612.

[0068] It should be noted that when the first film tearing assembly 610 tears off the lower protective film on the lower adhesive film, the fourth driver 611 drives the first adsorption structure 613 to move forward and upward along the first slide rail 612, so that the first adsorption structure 613 can approach and adsorb the lower protective film on the lower adhesive film. Then, the fourth driver 611 drives the first adsorption structure 613 to move backward and downward along the first slide rail 612, so that the first adsorption structure 613 drives the lower protective film on the lower adhesive film to separate from the lower adhesive film to complete the tearing of the lower adhesive film.

[0069] It can be understood that since the extension direction of the first slide rail 612 is spaced apart from the extension direction of the preset path by a certain angle in the vertical direction, when the fourth driver 611 drives the first adsorption structure 613 to move in the opposite direction of the preset path, the first adsorption structure 613 can simultaneously move downward away from the lower adhesive film on the preset path, thereby enabling the lower protective film to be torn off the lower adhesive film more smoothly.

[0070] It should be noted that, since the lower adhesive film is adhered to the lower protective film, when the first film tearing assembly 610 is tearing off the lower protective film, the lower protective film may drive the lower adhesive film to separate from the film material.

[0071] Based on the above problems, in some embodiments of the present invention, reference Figure 8 , Fig. 9 and Fig.11 The film tearing module 600 also includes a film material limiting frame 630, and the film material limiting frame 630 is provided with a first abutting surface 632a for abutting against the lower adhesive film of the film material; the first adsorption structure 613 includes a first lifting driver 613a and a first suction head 613b, the first suction head 613b is used to adsorb the lower protective film on the lower adhesive film, and the first lifting driver 613a is used to drive the first suction head 613b to perform lifting movement.

[0072] For example, Figure 8 , Fig. 9 and Fig.11 As shown, the film material limiting frame 630 is provided with a second guide groove 631 extending forward and backward, the second guide groove 631 is opened downward, and the two groove edges at the lower end of the second guide groove 631 are provided with a first abutment member 632 extending toward the middle of the second guide groove 631, and the upper end surface of the first abutment member 632 forms a first abutment surface 632a; the first adsorption structure 613 includes a first lifting driver 613a and a first suction head 613b, the first lifting driver 613a is slidably arranged on the first slide rail 612, and the output end of the first lifting driver 613a is connected to the first suction head 613b.

[0073] Furthermore, when the first film tearing assembly 610 is tearing off the lower protective film on the lower adhesive film, the fourth driver 611 drives the first lifting driver 613a to move forward along the first slide rail 612, so that the first lifting driver 613a is close to the lower adhesive film on the film material, and then, the first lifting driver 613a drives the first suction head 613b to move upward, so that the first suction head 613b is close to and adsorbs the lower protective film of the lower adhesive film, and then, the first lifting driver 613a drives the first suction head 613b to move downward, so that the first suction head 613b tears part of the lower protective film off the lower adhesive film, and then, the fourth driver 611 drives the first adsorption structure 613 to move backward, so that the first suction head 613b drives the adsorbed lower protective film to be completely torn off the lower adhesive film.

[0074] It can be understood that since the film material limiting frame 630 is provided with a first abutting surface 632a for abutting against the lower adhesive film of the film material, during the process of the first film tearing assembly 610 tearing off the lower protective film on the surface of the lower adhesive film, the first abutting surface 632a abuts against the lower adhesive film to prevent the lower adhesive film from following the lower protective film from leaving the film material.

[0075] In some embodiments of the present invention, reference Figure 8 and Fig.10 The second film tearing assembly 620 includes a seventh driver 621, a second slide rail 622 and a second adsorption structure 623. The second adsorption structure 623 is slidably disposed on the second slide rail 622 and is used to adsorb the upper protective film on the upper glue film. The extension direction of the second slide rail 622 is spaced apart from the extension direction of the preset path by a certain angle. The seventh driver 621 is connected to the second adsorption structure 623 and is used to drive the second adsorption structure 623 to slide along the second slide rail 622.

[0076] For example, Figure 8 and Fig.10 As shown, the extension direction of the preset path is the front-to-back direction, the second slide rail 622 is arranged below the preset path and extends along the right front direction, the second adsorption structure 623 is arranged on the second slide rail 622 and connected to the output end of the seventh driver 621. Driven by the seventh driver 621, the second adsorption structure 623 slides along the second slide rail 622.

[0077] It should be noted that when the second film tearing assembly 620 tears off the upper protective film on the upper glue film, the seventh driver 621 drives the second adsorption structure 623 to move to the left rear along the second slide rail 622, so that the second adsorption structure 623 can approach and adsorb the upper protective film on the upper glue film. Then, the seventh driver 621 drives the second adsorption structure 623 to move to the right front along the second slide rail 622, so that the second adsorption structure 623 drives the upper protective film on the upper glue film to separate from the upper glue film to complete the tearing of the upper glue film.

[0078] It can be understood that since the extension direction of the second slide rail 622 is horizontally spaced from the extension direction of the preset path by a certain angle, when the seventh driver 621 drives the second adsorption structure 623 to move in the opposite direction of the preset path, the second adsorption structure 623 can simultaneously move to the right away from the upper adhesive film on the preset path, thereby enabling the upper protective film to be torn off the upper adhesive film more smoothly.

[0079] It should be noted that, since the upper glue film is adhered to the upper protective film, when the second film tearing assembly 620 is tearing off the upper protective film, the upper protective film may cause the upper glue film to separate from the film material.

[0080] Based on the above problems, in some embodiments of the present invention, the film material limiting frame 630 is also provided with a second abutting surface 634a for abutting against the upper glue film of the film material; the second adsorption structure 623 includes a second lifting driver 623a and a second suction head 623b, the second suction head 623b is used to adsorb the upper protective film on the upper glue film, and the second lifting driver 623a is used to drive the second suction head 623b to perform lifting and lowering movements.

[0081] For example, Figure 8 , Fig.10 and Fig.12 As shown, the film material limiting frame 630 is provided with a third guide groove 633 extending forward and backward, the third guide groove 633 is open upward, and the two groove edges at the upper ends of the third guide groove 633 are provided with a second abutment member 634 extending toward the middle of the third guide groove 633, and the lower end surface of the second abutment member 634 forms a second abutment surface 634a; the second adsorption structure 623 includes a second lifting driver 623a and a second suction head 623b, the second lifting driver 623a is slidably arranged on the second slide rail 622, and the output end of the second lifting driver 623a is connected to the second suction head 623b.

[0082] Furthermore, when the second film tearing assembly 620 is tearing off the upper protective film on the upper glue film, the seventh driver 621 drives the second lifting driver 623a to move to the left rear along the second slide rail 622, so that the second lifting driver 623a is close to the upper glue film on the film material, and then, the second lifting driver 623a drives the second suction head 623b to move downward, so that the second suction head 623b is close to and adsorbs the upper protective film of the upper glue film, and then, the second lifting driver 623a drives the second suction head 623b to move upward, so that the second suction head 623b tears part of the upper protective film off the upper glue film, and then, the seventh driver 621 drives the second adsorption structure 623 to move to the right front, so that the second suction head 623b drives the adsorbed upper protective film to be completely torn off the upper glue film.

[0083] It can be understood that since the film material limiting frame 630 is provided with a second abutting surface 634a for abutting against the upper adhesive film of the film material, during the process of the second film tearing assembly 620 tearing off the upper protective film on the surface of the upper adhesive film, the second abutting surface 634a abuts against the upper adhesive film to prevent the upper adhesive film from following the upper protective film from leaving the film material.

[0084] In some embodiments of the present invention, reference Figure 1 The adhesive film supply module 400 includes an adhesive film conveyor line 410 and a transport robot 420. The adhesive film conveyor line 410 is used to convey the adhesive film. The transport robot 420 is arranged between the adhesive film conveyor line 410 and the fixture transfer assembly 100, and is used to transport the adhesive film on the adhesive film conveyor line 410 and bond it to the film material of the bonding station 101.
