Description

Technical Field

[0001] This invention relates to the field of film application device technology, and particularly to a film application device. Background Technology

[0002] During the membrane material processing, an upper adhesive film and a lower adhesive film need to be applied to the upper surface of the membrane material. Since the existing film application equipment can only apply film to one side of the membrane material at a time, after the existing film application equipment completes the application of the upper adhesive film on the upper surface of the membrane material, the operator needs to roll up the membrane material with the upper adhesive film applied, and then unroll the membrane material with the lower surface facing up into the film application equipment to complete the application of the lower adhesive film on the lower surface of the membrane material. The entire film application process is quite cumbersome. Summary of the Invention

[0003] The purpose of this invention is to at least solve one of the technical problems existing in the prior art. This invention provides a film-applying device that can simultaneously complete the bonding of adhesive films on both sides of a film material.

[0004] According to an embodiment of the present invention, a film-applying device includes a lower adhesive film supply module, a film material conveying module, a film material lifting module, and an upper adhesive film supply module. The lower adhesive film supply module includes a fixture transfer assembly and a lower adhesive film loading assembly. The fixture transfer assembly is provided with a bonding station and a loading station. The fixture transfer assembly is used to drive the fixture to reciprocate between the bonding station and the loading station. The lower adhesive film loading assembly is located on one side of the fixture transfer assembly and is used to load the lower adhesive film onto the fixture at the loading station. The film material conveying module is located on one side of the lower adhesive film supply module and is used to drive the film material to move along a preset path to the bonding station. The film material lifting module is located on the preset path and is used to drive the film material to perform lifting and lowering movements so that the lower surface of the film material is bonded to the lower adhesive film at the bonding station. The upper adhesive film supply module is located on one side of the lower adhesive film supply module and is used to bond the upper adhesive film to the upper surface of the film material at the bonding station.

[0005] The film-applying device of this invention has at least the following beneficial effects: In the film-applying device of this application, the lower adhesive film feeding assembly can feed the lower adhesive film onto the fixture at the feeding station. Driven by the fixture transfer assembly, the fixture carrying the lower adhesive film can move from the feeding station to the bonding station. Driven by the film material conveying module, the film material can be conveyed to the bonding station and positioned directly above the fixture. At this time, the film material lifting module can drive the film material downward so that the lower surface of the film material approaches and bonds with the lower adhesive film on the fixture. Then, the upper adhesive film supply module can convey the upper adhesive film to the bonding station and bond the upper adhesive film to the upper surface of the film material. Thus, the film-applying device of this application can complete the bonding of the upper and lower adhesive films onto the upper and lower surfaces of the film material in one step.

[0006] According to the film application device of the present invention, the film lifting module includes a first driver and a lifting seat.

The cylinder is connected to the first hook and is used to drive the first hook to perform lifting and lowering movements. A second hook is provided on the floating plate. When the rotary table drives the fixture to rotate in the forward direction to enter the bonding station, the second hook engages with the first hook. When the rotary table drives the fixture to rotate in the reverse direction to leave the bonding station, the second hook disengages from the first hook.

[0010] According to the embodiments of the present invention, the film-applying device further includes a pressure-holding module, which is disposed on a preset path and is used to hold pressure on the upper adhesive film and the lower adhesive film on the film material.

[0011] According to the film-applying device of the present invention, the pressure-holding module includes a pressure-holding block and a driving component. The driving component is connected to the pressure-holding block and can drive the pressure-holding block to move closer to or away from the fixture on the bonding station.

The film-tearing module includes a first film-tearing component and a second film-tearing component. The first film-tearing component is used to peel off the lower adhesive film on the film material, and the second film-tearing component is used to peel off the upper adhesive film on the film material.

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0039] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0040] The following is for reference. Figures 1 to 12 The film application device of this application will be described in detail.

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

[0042] For example, such as Figure 1 and Figure 4As shown, the lower adhesive film supply module 10 includes a fixture transfer assembly 100 and a lower adhesive film loading assembly. The fixture transfer assembly 100 is provided with a bonding station 101 and a loading station 102. The loading station 102 is located to the left of the bonding station 101. The fixture transfer assembly 100 is used to drive the fixture 130 to move cyclically between the bonding station 101 and the loading station 102. The lower adhesive film loading assembly is located on one side of the fixture transfer assembly 100 and is used to load the lower adhesive film onto the loading station. The fixture 130 is located within position 102; the membrane material conveying module 200 is located on the front side of the fixture transfer assembly 100 and is used to drive the membrane material to move from back to front so that the membrane material can pass through the bonding station 101; the membrane material lifting module 300 is located on the rear side of the fixture transfer assembly 100 and is used to drive the membrane material to perform lifting and lowering movements; the adhesive film supply module 400 is located on the right side of the fixture transfer assembly 100 and is used to apply the adhesive film to the upper surface of the membrane material at the bonding station 101.

[0043] Furthermore, in the operation of the film-applying apparatus of this application, the film material conveying module 200 can drive the film material to move from back to front, so that the film material moves to the bonding station 101; the lower adhesive film loading component can load the lower adhesive film onto the fixture 130 at the loading station 102; then, driven by the fixture transfer component 100, the fixture 130 loading the lower adhesive film moves from the loading station 102 to the bonding 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 bonded to the lower adhesive film on the fixture 130; immediately afterward, the upper adhesive film supply module 400 can bond the upper adhesive film to the upper surface of the film material at the bonding station 101; thus completing the bonding of the upper adhesive film and the lower adhesive film on the upper and lower surfaces of the film material, respectively.

[0044] As can be seen from the above, the film application device of this application can complete the application of the upper adhesive film and the lower adhesive film on the upper and lower surfaces of the film material in one step, saving time and effort.

[0045] In some embodiments of the present invention, reference is made to Figure 2 The membrane 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 a vertical direction. The first limiting surface 321 is located above the second limiting surface 322. A material passage is formed between the first limiting surface 321 and the second limiting surface 322 to allow the membrane material to pass through. 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 is understandable that when the membrane lifting module 300 needs to push the membrane material downward, the first driver 310 can drive the lifting seat 320 downward so that the first limiting surface 321 pushes the membrane material downward; when the membrane lifting module 300 needs to push the membrane material upward, the first driver 310 can drive the lifting seat 320 upward so that the second limiting surface 322 pushes the membrane material upward.

[0047] In a further embodiment of the invention, reference is made to... Figure 3 The lifting seat 320 is provided with a first guide groove 323 extending back and forth. The two groove edges at the upper end of the first guide groove 323 extend towards the middle of the first guide groove 323 to form two abutting protrusions 324. The lower end surface of the abutting protrusions 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 fixture transfer assembly 100 includes a second driver 110, a rotary table 120 and a fixture 130. The fixture 130 is disposed on the rotary table 120. The second driver 110 is connected to the rotary table 120 and is used to drive the rotary table 120 to rotate so that the fixture 130 cyclically passes through the loading station 102 and the bonding station 101.

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

[0050] Understandably, driven by the second driver 110, the rotary table 120 can rotate around the vertical axis so that the fixture 130 can move cyclically between the loading station 102 and the bonding station 101.

[0051] It is understood that by setting two fixtures 130 on the rotary table 120, when one fixture 130 is located at the bonding station 101, the other fixture 130 is located at the loading station 102 to wait for the loading of the lower adhesive film loading assembly, thereby improving the working efficiency of the film bonding device in this embodiment.

[0052] In some embodiments of the present invention, reference is made to Figure 6The fixture 130 includes a fixture body 131 and a floating plate 132. The floating plate 132 is buoyantly disposed at the lower end of the fixture body 131 in a vertical direction. The fixture body 131 is provided with an insertion hole that passes through the fixture body 131 in a 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 disposed in the insertion hole. The fixture transfer assembly 100 also includes a third driver 140. The third driver 140 is disposed at the bonding station 101 and is used to drive the floating plate 132 at the bonding station 101 to perform lifting and lowering movements so that the positioning rod 133 extends or retracts into the insertion hole.

[0053] Understandably, before the membrane lifting module 300 drives the membrane to move downward so that the lower surface of the membrane approaches and adheres to the lower adhesive 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 retract downward into the insertion hole to avoid the membrane.

[0054] It should be noted that, since the floating plate 132 needs to follow the fixture 130 to move cyclically between the bonding station 101 and the loading station 102, and the third driver 140 is located at the bonding station 101 and cannot follow the fixture 130, when the fixture 130 moves to the bonding station 101, the driving end of the third driver 140 needs to be connected to the floating plate 132, and when the fixture 130 leaves the bonding 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 is made to Figure 5 and Figure 6 The third drive 140 includes a cylinder 141 and a first hook 142, and a second hook 132a is provided on the floating plate 132.

[0056] Furthermore, when the rotary table 120 drives the fixture 130 to rotate in the forward direction to enter the bonding station 101, the second hook 132a engages 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 rotary table 120 drives the fixture 130 to rotate in the reverse direction to leave the bonding station 101, the second hook 132a disengages from the first hook 142.

[0057] In some embodiments of the present invention, reference is made to Figure 5 and Figure 6 The fixture 130 also includes a mounting plate 134, which is connected to the lower end face of the rotary table 120. The fixture body 131 is connected to the upper end face of the rotary table 120. A floating plate 132 is disposed 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 by a spring 135.

[0058] Furthermore, under the elastic force of the spring 135, the floating plate 132 can abut against the fixture body 131 upwards, 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 fixture 130. When the fixture 130 is located at the bonding station 101, the first hook 142 and the second hook 132a are engaged. The cylinder 141 can drive the second hook 132a to move downwards 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 and move downwards. At this time, the insertion rod retracts downwards into the insertion hole to avoid the film material.

[0059] In order to ensure that the upper and lower adhesive films adhere more firmly to the film material, in some embodiments of the present invention, reference is made to... Figure 1 The film application device also includes a pressure holding module 500, which is located on a preset path of the film material and is used to maintain pressure on the upper and lower adhesive films on the film material.

[0060] Understandably, by setting up the pressure-holding module 500, after the upper and lower adhesive films are bonded to the membrane material, the pressure-holding module 500 can hold pressure on the upper and lower adhesive films on the membrane material, so that the upper and lower adhesive films can be bonded to the membrane material more firmly, thereby reducing the probability of the upper or lower adhesive films automatically falling off the membrane material.

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

[0062] For example, such as Figure 7 As shown, the drive assembly 520 includes a horizontal drive structure and a vertical drive structure. The horizontal drive 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 drive structure includes a pressure base 523 and a sixth driver 524. The pressure base 523 is slidably disposed on the guide rail 521a and connected to the output end of the fifth driver 522. The sixth driver 524 is disposed on the pressure base 523 and connected to the pressure block.

[0063] Furthermore, driven by the fifth actuator 522, the pressure block 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 actuator 524, the pressure block can move up and down, so that the pressure block moves closer to or away from the fixture 130 in the bonding station 101, thereby enabling the pressure block to cooperate with the fixture 130 to complete the pressure holding of the adhesive film and the under-adhesive film on the surface of the film material.

[0064] It should be noted that the upper adhesive film has an upper protective film, and the lower adhesive film has a lower protective film. After the upper and lower adhesive films are applied to the film material, they need to be peeled off separately to remove the upper protective film on the upper adhesive film and the lower protective film on the lower adhesive film.

[0065] For the reasons stated above, in some embodiments of the present invention, reference is made to... Figure 1 and Figure 8 The film application device also includes a film-tearing module 600, which is disposed 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 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 located above the film material and is used to tear 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-peeling 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 at a certain angle from the extension direction of the preset path. 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, such as Figure 8 and Figure 9 As shown, the extension direction of the preset path is the front-to-back direction. The first slide rail 612 is located below the preset path and extends in the front-up direction. The first adsorption structure 613 is located on the first slide rail 612 and is connected to the output end of the fourth driver 611. Under the drive of 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 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 detach from the lower adhesive film, thereby completing the film-tearing of the lower adhesive film.

[0069] It is understandable that, since the extension direction of the first slide rail 612 is at a certain angle to the extension direction of the preset path in the vertical direction, when the fourth actuator 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, so that the lower protective film can be peeled off from the lower adhesive film more smoothly.

[0070] It should be noted that, since the lower adhesive film and the lower protective film are adhered to each other, during the process of the first film-tearing assembly 610 removing the lower protective film, the lower protective film may cause the lower adhesive film to detach from the film material.

[0071] Based on the above problems, in some embodiments of the present invention, reference is made to Figure 8 , Figure 9 and Figure 11 The film-peeling module 600 also includes a film material limiting frame 630, which has a first contact surface 632a for contacting 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, which 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 and lowering movements.

[0072] For example, such as Figure 8 , Figure 9 and Figure 11 As shown, the membrane material limiting frame 630 is provided with a second guide groove 631 extending forward and backward. The second guide groove 631 is opened downward. At the two groove edges at the lower end of the second guide groove 631, there are first abutting members 632 extending towards the middle of the second guide groove 631. The upper end surface of the first abutting member 632 forms a first abutting 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 disposed on the first slide rail 612. The output end of the first lifting driver 613a is connected to the first suction head 613b.

[0073] Then, when the first film-peeling assembly 610 peels 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 approaches the lower adhesive film on the film material. Then, the first lifting driver 613a drives the first suction head 613b to move upward, so that the first suction head 613b approaches and adsorbs the lower protective film of the lower adhesive film. Then, the first lifting driver 613a drives the first suction head 613b to move downward, so that the first suction head 613b peels part of the lower protective film off the lower adhesive film. Immediately afterwards, 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 peeled off the lower adhesive film.

[0074] It is understandable that, since the membrane material limiting frame 630 is provided with a first contact surface 632a for contacting the lower adhesive film of the membrane 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 contact surface 632a contacts the lower adhesive film to prevent the lower adhesive film from detaching from the membrane material along with the lower protective film.

[0075] In some embodiments of the present invention, reference is made to Figure 8 and Figure 10 The second film-peeling 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 adhesive film. The extension direction of the second slide rail 622 is spaced at a certain angle from the extension direction of the preset path. 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, such as Figure 8 and Figure 10 As shown, the extension direction of the preset path is the front-to-back direction. The second slide rail 622 is located below the preset path and extends along the right front direction. The second adsorption structure 623 is located on the second slide rail 622 and is connected to the output end of the seventh driver 621. Under the drive of 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-peeling assembly 620 peels the upper protective film on the adhesive film, the seventh driver 621 drives the second adsorption structure 623 to move to the left and rear along the second slide rail 622, so that the second adsorption structure 623 can approach and adsorb the upper protective film on the adhesive film. Then, the seventh driver 621 drives the second adsorption structure 623 to move to the right and front along the second slide rail 622, so that the second adsorption structure 623 drives the upper protective film on the adhesive film to detach from the adhesive film, thereby completing the peeling of the adhesive film.

[0078] It is understandable that, since the extension direction of the second slide rail 622 is at a certain angle to the extension direction of the preset path in the horizontal direction, when the seventh actuator 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 adhesive film on the preset path, so that the upper protective film can be peeled off from the adhesive film more smoothly.

[0079] It should be noted that, since the adhesive film and the upper protective film are adhered to each other, during the process of the second film-tearing assembly 620 removing the upper protective film, the upper protective film may cause the adhesive film to detach from the film material.

[0080] Based on the above problems, in some embodiments of the present invention, the membrane material limiting frame 630 is further provided with a second contact surface 634a for contacting the adhesive film of the membrane 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 adhesive 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, such as Figure 8 , Figure 10 and Figure 12 As shown, the membrane material limiting frame 630 is provided with a third guide groove 633 extending forward and backward. The third guide groove 633 is open upward. At the two groove edges at the upper end of the third guide groove 633, there are second abutment members 634 extending towards the middle of the third guide groove 633. 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 disposed on the second slide rail 622. The output end of the second lifting driver 623a is connected to the second suction head 623b.

[0082] Furthermore, when the second film-peeling assembly 620 peels off the upper protective film on the adhesive film, the seventh driver 621 drives the second lifting driver 623a to move to the left and rear along the second slide rail 622, so that the second lifting driver 623a approaches the adhesive film on the film material. Then, the second lifting driver 623a drives the second suction head 623b to move downward, so that the second suction head 623b approaches and adsorbs the upper protective film on the adhesive film. Then, the second lifting driver 623a drives the second suction head 623b to move upward, so that the second suction head 623b peels part of the upper protective film off the adhesive film. Immediately afterwards, the seventh driver 621 drives the second adsorption structure 623 to move to the right and front, so that the second suction head 623b completely peels off the adsorbed upper protective film from the adhesive film.

[0083] It is understandable that, since the membrane material limiting frame 630 is provided with a second contact surface 634a for contacting the upper adhesive film of the membrane 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 contact surface 634a contacts the upper adhesive film to prevent the upper adhesive film from detaching from the membrane material along with the upper protective film.

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