Description

[Technical field]

[0001] The invention relates to the field of thin film processing, in particular to a thin film processing system in the field of conductive film production. [Background technology]

[0002] The AD film structure includes the first UV (Ultraviolet Rays) adhesive layer, the second UV adhesive layer and the third UV adhesive layer. After the first UV adhesive layer is embossed, the lead area needs to be pasted with tape, and then the second UV adhesive layer is formed by loading and UV curing. The existing tape pasting and UV curing devices are carried out step by step. The production efficiency is low if the tape pasting is done first and then UV curing.

[0003] Tape is widely used in industrial production and daily life. However, in many occasions, it needs to be applied manually. Although manual operation can ensure the flexibility of its application, in large-scale production sites, this manual link often limits the speed of the entire process. In addition, in the process of manual application, due to factors such as the operator's proficiency and the speed of application, there will be different degrees of irregular application or bubbles in the application part. These defects caused by manual operation often affect the performance of the entire product or packaging. More importantly, there is often no industry scenario for the application of tape in the conductive film industry. If the tape is applied across industries to the conductive film production industry, it is an innovative application in itself. Further, how to realize the automated processing of tape film (automatic application or removal of tape) will be a technical problem worth solving, because the conductive film production field has unique industry characteristics, which are closely related to the characteristics of the conductive film material itself. If the application or removal of the tape is completely handled manually, the cost is high, the efficiency is low, and it is easy to make mistakes.

[0004] Therefore, it is necessary to propose an improved technical solution to overcome the above problems. [Summary of the invention]

The rolling of the rolling assembly can make the film segment gradually separated from the composite material strip stick together with the area to be film-sticked on the film. The composite material strip includes a base film and a film attached to one side of the base film. The composite material strip is driven to move along the first guide surface of the peeling mechanism body toward the peeling edge and is separated at the peeling edge. The stripping mechanism is separated into a base film located on a side close to the stripping mechanism body and a pasting film located on a side away from the stripping mechanism body, wherein the base film turns over the stripping edge and is driven to move along the second guide surface away from the stripping edge, and before the composite material strip is fed into the stripping mechanism, the pasting film on the composite material strip has been cut into pasting film segments of a predetermined length, while the base film on the composite material strip has not been cut and remains continuous, the stripping mechanism strips the cut pasting film segments of a predetermined length from the composite material strip, and the rolling assembly rolls the separated pasting film segments of a predetermined length onto the area to be pasted on the film.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] The term "one embodiment" or "embodiment" as used herein means that a particular feature, structure or characteristic associated with the embodiment may be included in at least one implementation of the present invention. The term "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor does it necessarily refer to a separate or selected embodiment that is mutually exclusive with other embodiments. The terms "multiple" and "several" in the present invention mean two or more. The term "and / or" in the present invention means "and" or "or".

[0035] According to one aspect of the present invention, the present invention provides a film sticking device, which can automatically stick a film on a target object such as a conductive film 5 by pasting or other means instead of manual work.

[0036] Figure 1 is a schematic diagram of a three-dimensional structure of a film-sticking device in one embodiment of the present invention from a viewing angle, Figure 2 for Figure 1 A three-dimensional structural diagram of the film laminating equipment from another perspective. Figure 1 and Figure 2As shown, two film sticking devices 1a and 1b are arranged one behind the other. In other embodiments, the number of the film sticking devices can be set as needed, such as 1, 3, 4 or more. The film sticking devices 1a and 1b can be used to stick the film on a target object such as a conductive film 5 by pasting or other means. The whole process does not require manual participation, which improves production efficiency and has high product consistency.

[0037] like Figure 1 and Figure 2 As shown, the film pasting equipment 1a or 1b includes a frame 50, a working platform 40 formed on the frame 50, a film pasting assembly 10, a film pasting position adjusting device 20, and a film pasting position positioning device 30.

[0038] The working platform 40 can carry the conductive film 5 and drive the conductive film 5 to move forward. The working platform 40 is driven by a platform power device, and a code disc 41 is arranged on the working platform 40. The code disc 41 is used to measure the movement speed of the conductive film 5 and feed the speed back to the platform power device. The platform power device controls the movement speed of the conductive film 5 based on the movement speed fed back by the code disc 41.

[0039] like Fig.12 As shown, the conductive film 5 includes a lead area 51 located at a designated position, and the film sticking assembly 10 of the present invention can stick a film 82 on the lead area 51 of the conductive film 5 to cover the lead area 51. In other embodiments, it is obvious that the working platform 40 can also transport other films or other items that need to be stuck with films, which can be collectively referred to as target objects to be stuck in the present invention, and the conductive film 5 is mainly used as an example for description in this article. The film 82 can also be a sticky film or a non-sticky film.

[0040] Figure 3 for Figure 1 A front 3D structural diagram of a film laminating device. Figure 3 As shown, the film-sticking position positioning device 30 can be used to locate the lateral position and longitudinal position of the lead area on the conductive film 5, wherein the longitudinal direction is the conveying direction X of the conductive film, referred to as the X direction, and the lateral direction is the perpendicular direction Y of the conveying direction of the conductive film, referred to as the Y direction. The film-sticking position positioning device 30 includes a camera 31, a light source 32 and an image recognition unit (not shown). The camera 31 is used to photograph the conductive film 5, and the light source 32 is used to provide fill light when the camera 31 is photographing. The image recognition unit is used to recognize the lateral position and longitudinal position of the lead area of ​​the conductive film 5 based on the image photographed by the camera 31.

[0041] Combination Figure 3 As shown, the film-sticking position adjustment device 20 includes a transverse guide rail 21 fixed on the frame 50 and extending laterally, a transverse slider 22 capable of sliding on the transverse guide rail 21, and a slider driving device 23. The film-sticking assembly 10 is connected to the transverse slider 22, and the slider driving device 23 can drive the transverse slider 22 to move laterally along the transverse guide rail 21, and the transverse movement of the transverse slider 22 can drive the transverse movement of the film-sticking assembly 10. In this way, even if the conductive film 5 is laterally offset during transportation, the film-sticking position adjustment device 20 can adjust the transverse position of the film-sticking assembly 10 based on the transverse position of the lead area obtained by positioning, so that the film can be attached to the lead area of ​​the conductive film more accurately. The slider driving device 23 can be a motor.

[0042] In some embodiments, the film sticking position adjustment device 20 may not be provided. In this case, the film sticking assembly 10 may be directly fixed on the frame 50, so that the lateral position of the film sticking assembly 10 cannot be adjusted. In order to ensure the normal operation of the film sticking equipment, it is necessary to ensure that the position deviation of the conductive film 5 transmitted by the working platform 40 is acceptable.

[0043] In some embodiments, the film position positioning device 30 may not be provided. In this case, the film pasting equipment needs to know the position of the lead area of ​​the conductive film 5 in advance. As long as the position of the lead area of ​​the conductive film 5 does not shift, the film pasting assembly 10 can automatically adhere the film 82 to the lead area 51 of the conductive film 5.

[0044] Figure 4 for Figure 3 A schematic diagram of the side structure of the film laminating device in FIG. Figure 5 for Figure 3 The film laminating assembly 10 includes a peeling mechanism 100, a rolling assembly 200, a feeding mechanism 300, a material returning mechanism 400, a half-cutting device 500, a length adjusting device 600, a film laminating assembly base 700 and a film laminating assembly base driving device 800.

[0045] The stripping mechanism 100, the rolling assembly 200, the feeding mechanism 300, the material return mechanism 400, the half-cutting device 500, and the length adjustment device 600 are all arranged on the film assembly base 700. The movement of the film assembly base 700 can drive the stripping mechanism 100, the rolling assembly 200, the feeding mechanism 300, the material return mechanism 400, the half-cutting device 500, and the length adjustment device 600 to move synchronously. One end of the film assembly base driving device 800 is fixed on the transverse slider 21, and the other end is fixed on the film assembly base 700. The film assembly base driving device 800 can drive the film assembly base 700 to move between the initial position and the downward pressing position. Preferably, the film assembly base driving device 800 can be a cylinder.

[0046] Figure 6 for Figure 3 Schematic diagram of the three-dimensional structure of the peeling mechanism 100. Figure 6 As shown, the stripping mechanism 100 includes a stripping mechanism body 110 and a stripping edge 120 located at the end of the stripping mechanism body 110, the stripping mechanism body 110 includes a first guide surface 111 and a second guide surface 112, the first guide surface 111 and the second guide surface 112 intersect at the stripping edge 120. The rolling assembly 200 includes a first pressing roller 210 and a second pressing roller 220 that are spaced apart, the first pressing roller 210 being closer to the stripping edge 120 of the stripping mechanism 100 than the second pressing roller 220. The first pressing roller 210 and the second pressing roller 220 both have an initial state and a pressing state. Fig.10 FIG. 8 is a schematic diagram of the structure of the composite material strip 80 in the present invention. Fig.10 As shown, the composite material strip 80 includes a base film 81 and a film 82 attached to one side of the base film 81 , wherein a first surface of the film 82 attached to the base film 81 is adhesive, and a second surface of the film 82 opposite to the first surface is non-adhesive.

[0047] like Figure 8 As shown, the composite material strip 80 is driven to move along the first guide surface 111 of the peeling mechanism body 110 toward the peeling edge 120, and is separated at the peeling edge 120 into a base film 81 located on a side close to the peeling mechanism body 110 and a pasting film 82 located on a side away from the peeling mechanism body 110, wherein the base film 81 turns over the peeling edge 120 and is driven to move along the second guide surface 112 away from the peeling edge 120. Preferably, as Figure 6 As shown, the film edge 120 may be a curved edge rather than a sharp edge, which may facilitate the base film 81 to pass through the peeling edge 120 smoothly.

[0048] In order to facilitate the stripping of the composite tape 80, Figure 6 and 7 As shown, the angle between the first guide surface 111 and the second guide surface 112 can be less than 15 degrees, such as 10 degrees, 12 degrees, etc. The first side of the stripping mechanism body 110 forming the first guide surface 111 is provided with a guide groove 130, and the bottom surface of the guide groove 130 is the first guide surface 111. The guide groove 130 is used to guide the composite material strip 80. The width of the guide groove 130 can match the width of the material strip.

[0049] The first side of the peeling mechanism body 110 is provided with an arc-shaped pit 140 near the peeling edge, and the arc-shaped pit 140 matches and is arranged close to the outer edge of the first pressing roller 210, but does not contact the arc-shaped pit of the peeling mechanism. In this way, the pressing part 211 of the first pressing roller 210 can be as close as possible to the peeling edge 120 of the peeling mechanism 100, so that the first pressing roller 210 can more easily press the separated film 82.

[0050] like Figure 8 As described above, when in the pressed state, the first pressing roller 210 and the second pressing roller 220 are sequentially pressed on the non-sticky second surface of the separated film 82 , so that the first surface of the film 82 is adhered to the lead area of ​​the conductive film 5 carried on the working platform 40 .

[0051] like Figure 7 As shown, the first pressing roller 210 and the film-mounting assembly base 700 move synchronously. When the film-mounting assembly base 700 is in the initial position, the first pressing roller 210 is in the initial state. At this time, the first pressing roller 210 is separated from the conductive film 5 on the working platform 40 by a distance. Figure 8 As shown, when the film-mounting assembly base 700 is driven to the downward pressing position by the film-mounting assembly base driving device 800, the first pressing roller 210 is pressed downward together with the film-mounting assembly base 700 to enter the pressing state, and at this time, the first pressing roller 210 is pressed on the conductive film 5 on the working platform 40. Specifically, the timing of switching the stripping mechanism 100 from the initial state to the pressing state can be determined based on the longitudinal position of the lead area obtained by the film-mounting position positioning device 20, so that the stripping mechanism 100 can be aligned with the lead area in the pressing state.

[0052] like Figure 5As shown, the film sticking assembly 10 also includes a pressure roller driving device 221 disposed on the film sticking assembly base 700. One end of the pressure roller driving device 221 is fixedly connected to the film sticking assembly base 700, and the other end is fixedly connected to the second pressure roller 220. The pressure roller driving device 221 drives the second pressure roller 220 to switch between the initial state and the pressing state. The second pressure roller 220 moves independently of the first pressure roller 210. The second pressure roller 220 can enter the pressing state from the initial state later than, earlier than, or at the same time as the first pressure roller 210, as long as the second pressure roller 220 can press the separated film 82 in time. However, the second pressure roller 220 usually returns to the initial state from the pressing state at a predetermined time later than the first pressure roller 210, as shown in FIG. Figure 8 and Fig. 9 , so that the second pressing roller 220 can press the separated film 82 from the beginning to the end. The pressing roller driving device 221 can be a cylinder.

[0053] The feeding mechanism 300 is used to convey the composite material strip 80 to the stripping mechanism 100, and its movement direction is as follows: Figure 8 D1 in the figure, the material return mechanism 400 is used to take away the base film 81 on the composite material strip 80 from the stripping mechanism 100, and its movement direction is as follows Figure 8 When the rolling assembly 200 is in the pressed state, the composite material strip 80 is driven by the feeding mechanism 300 and / or the returning mechanism 400, and moves synchronously with the conductive film 5 on the working platform 40. The moving direction of the conductive film 5 on the working platform 40 is as shown in FIG. Figure 8 In the direction X, the film 82 gradually separated from the composite material strip 80 is adhered to the lead area of ​​the conductive film 5 by the rolling of the rolling assembly 200. The rotation direction of the first pressing roller 210 can be seen in Figure 8 The rotation direction of the first pressing roller 210 can be seen from r2 in Figure 8 The rotation direction of the guide roller 320 is shown in FIG. Figure 8 r1 in.

[0054] like Figure 4As shown, the feeding mechanism 300 includes a discharge tray 310 and one or more guide rollers 320, and the return material mechanism 400 includes one or more guide rollers 410, a driving roller 421, a driven roller 422, a return material tray 430 and a return material driving device 440. The return material driving device 440 drives the driving roller 421, the driven roller 422 and the return material tray 430 to rotate, thereby driving the composite material strip 80 and the base film 81 to move. A brake is provided on the discharge tray 310 to provide a certain resistance for the discharge tray 310. The brake can be a magnetic powder brake. The return material driving device 440 can be a synchronous motor. The driven roller 422 can move between the clamping position and the away position under the drive of the roller driving device 4221. When the driven roller 422 is in the clamping position, the base film 81 is clamped between the driving roller 421 and the second driving roller 422. The roller driving device 4221 can be a cylinder. When the composite material strip 80 needs to be replaced, the roller driving device 4221 drives the driven roller to lift up and replace the composite material strip.

[0055] like Fig.11 As shown, the half-cutting device 500 can be used to cut the film 82 on the composite material strip 80 into film segments 82n of a predetermined length L before the composite material strip 80 is fed into the stripping machine 100. The half-cutting device 80 includes a half-cutting knife 510 and a half-cutting driving device 520. The half-cutting driving device 520 drives the half-cutting knife 510 to perform a cutting action, and the half-cutting knife 510 cuts the film 82 on the composite material strip 80 into film segments 82n of a predetermined length.

[0056] The length adjustment device 600 can adjust the predetermined length L of the film-applying section. The length adjustment device 600 includes a slit sensor 610 and a scale plate 620. The length of the adhesive tape between the slit sensor 610 and the peeling edge 120 of the peeling mechanism 100 is equal to a positive integer multiple of the predetermined length L, such as 1 or 2 times. After the slit sensor 610 senses the slit, the composite tape 80 is stopped from being fed into the peeling mechanism 100. At the same time, the film-applying assembly base 700 returns from the pressing position to the initial position, and the first pressing roller 210 and the peeling mechanism 100 return from the pressing state to the initial state.

[0057] For ease of understanding, the following Figure 7-Figure 9 The film sticking principle of the film sticking equipment is introduced in detail.

[0058] like Figure 7 As shown, the peeling mechanism 100, the first pressing roller 210 and the second pressing roller 220 are all in the initial state, and the working platform 40 drives the conductive film 5 thereon to move forward in the X direction. Figure 7-9 The working platform 40 is intentionally omitted in the figure, but in fact the working platform 40 is located below the conductive film 5. At this time, the feeding mechanism 300 and the receiving mechanism 400 can remain stationary.

[0059] When the conductive film 5 moves to the specified position, the film assembly base driving device 800 drives the film assembly 10 to press down. Figure 8 As shown, at this time, the stripping mechanism 100 and the first pressing roller 210 have entered the clamping state from the initial state, and the second pressing roller 220 has also entered the clamping state from the initial state driven by the pressing roller driving device 221. At this time, the composite material strip 80 is driven by the feeding mechanism 300 and / or the returning mechanism 400 and moves synchronously with the conductive film 5 on the working platform 40, that is, the movement speed of the conductive film 5 is substantially consistent with the movement speed of the composite material strip 80. The film segment 82n of a predetermined length gradually separated from the composite material strip 80 is successively pressed by the first pressing roller 210 and the second pressing roller 220 and pasted together with the lead area of ​​the conductive film 5. Specifically, whether the conductive film 5 moves to the specified position can be determined based on the longitudinal position of the lead area located by the film position positioning device 20 and the movement speed of the conductive film.

[0060] After a period of time, when the slit sensor 610 senses the slit of the conductive film 5, the film assembly base 700 is driven to return from the pressed position to the initial position, and the first pressing roller 210 is restored from the pressed state to the initial state, and the composite material strip 80 is stopped from being fed into the stripping mechanism 100. Fig. 9 As shown, at this time, the peeling mechanism 100 and the first pressing roller 210 have been restored from the pressing state to the initial state, and the second pressing roller 220 is still in the pressing state, so that the second pressing roller 220 can press the separated film segment 82n from the beginning to the end.

[0061] After a predetermined delay, the second pressing roller 220 is driven to recover from the pressing state to the initial state, so that the film tearing device returns to the initial state. Figure 7 The state shown. So far, one film pasting process is completed, and the above process can be repeated to complete multiple film pastings.

[0062] In a preferred embodiment, before the first pressing roller 210 enters the pressing state, the composite material strip 80 is fed into the stripping mechanism 100 for pre-stripping to obtain a film of pre-stripping length M, and after the first pressing roller 210 enters the pressing state, the composite material strip 80 is continuously fed into the stripping mechanism 100 for further stripping to obtain a film of the remaining length LM of the predetermined length L. The pre-stripping length M is greater than or equal to the distance from the stripping edge 120 to the bottom of the first pressing roller 210. After the pre-stripping of the composite material strip is completed, the half-cutting device 500 cuts the film 82 on the composite material strip 80, and the sum of the length of the composite material strip between the half-cutting device 500 and the slit sensor 610 of the length adjustment device 600 and the pre-stripping length M is equal to the predetermined length L. Because the composite material strip 80 is fed into the stripping mechanism 100 for pre-stripping to obtain a pre-stripped film of length M before the first pressing roller 210 enters the pressing state, the first pressing roller 210 can directly press the pre-stripped film of length M when entering the pressing state, so that the laminating process between the film section and the lead area can be started normally. If the composite material strip 80 is not pre-stripped before the first pressing roller 210 enters the pressing state, the peeled film may sometimes curl when entering between the first pressing roller 210 and the lead area of ​​the conductive film 5, which may easily lead to film laminating failure.

[0063] In a specific embodiment: for example, if a film section with a length of 50 mm (i.e., L=50 mm) is required, the position of the length adjustment device 600 is adjusted so that the scale indicated by it is 45 mm (where 5 mm is the pre-peeling length M, which needs to be deducted), and the composite material strip 80 is driven to move from the discharge tray 310 to the peeling mechanism 100. At this time, the film assembly base 700 is not pressed down, and pre-peeling is performed. The pre-peeling length M is 5 mm, that is, the return material driving device 440 moves 5 mm first. When the lead area of ​​the conductive film 5 moves to the specified position, the film assembly base driving device 800 is driven The film pasting component base 700 is pressed down. At this time, the speed of the return material driving device 440 is synchronized with the transmission speed of the conductive film 5. The pressure roller driving device 221 drives the second pressure roller 220 to press down as well to perform the film pasting work. At this time, the length of the subsequent film pasting is 45 mm. When the slit sensor 610 on the length adjustment device 600 detects the slit on the composite material strip, the film pasting component base driving device 800 drives the film pasting component base 700 to be lifted up. At this time, the second pressure roller 220 is still pressed down. When the second pressure roller 220 has pasted the last 5 mm, the second pressure roller 220 is also lifted up, and the above steps are repeated.

[0064] In a modified embodiment, before the composite material strip 80 is placed on the material discharging tray 310, the film 82 in the composite material strip 80 has been cut into film segments of a predetermined length L in advance, and at this time, the film assembly 10 may not be provided with the half-cutting device 500. In this embodiment, the slit sensor 610 still needs to function normally. When the slit sensor 610 senses the slit, it stops feeding the composite material strip 80 into the stripping mechanism 100, and controls the film assembly base 700 to return from the pressed position to the initial position.

[0065] It can be seen that the timing of pausing the feeding of the feeding mechanism 300 and / or the material collection of the return mechanism 400, and the timing of controlling the film assembly base 700 to return from the pressing position to the initial position are determined based on the slit signal sensed by the slit sensor 610. The timing of starting the feeding of the feeding mechanism 300 and / or the material collection of the return mechanism 400, and the timing of controlling the film assembly base 700 to enter the pressing position from the initial position are determined based on the longitudinal position of the lead area of ​​the conductive film 5 located by the film position positioning device 30.

[0066] In a replaceable embodiment, the pressure roller assembly 200 may also include only one pressure roller, such as the first pressure roller 210 or the second pressure roller 220. When the pressure roller assembly 200 includes one pressure roller, the pressure roller needs to roll all the film segments 82n to be pasted before it can return to the initial state from the pressing state. At this time, the pressure roller can switch between the pressing state and the initial state synchronously with the peeling mechanism 100, or can switch between the pressing state and the initial state asynchronously.

[0067] In a modified embodiment, the feeding mechanism 300 and the return mechanism 400 may also adopt other structural forms, for example, the number and position of the guide rollers 410, 320 may be adjusted as needed, the discharge tray 310 may also adopt other discharge structures, and the return tray 430 may adopt other existing return structures. In fact, as long as the feeding mechanism 300 can transfer the composite film 80 to the stripping mechanism 100, as long as the return mechanism 400 can recycle the base film 81, as long as the feeding mechanism 300 and / or the return mechanism 400 can drive the composite film 80 and the base film 81 to move, it will be sufficient.

[0068] In a modified embodiment, the length adjustment device 600 may not be provided, and the length of the film section 82n may be fixed instead of adjustable, which can fully meet the needs in some customized applications. However, the slit sensor 610 in the length adjustment device 600 is still required, but in this case, the slit sensor 610 no longer belongs to the length adjustment device 600.

[0069] In another modified embodiment, the peeling mechanism 100, the rolling assembly 200, the feeding mechanism 300, the material returning mechanism 400, the half-cutting device 500, and the length adjusting device 600 can be independently arranged, and not necessarily all arranged on the film laminating assembly base 700. According to the application requirements, the peeling mechanism 100 and the first pressing roller 210 may not move synchronously with the film laminating assembly base 700, but may have their own independent driving device, so that the peeling mechanism 100 and the first pressing roller 210 may not move synchronously, but may be arranged according to the requirements to see whether synchronous movement or asynchronous movement is required.

[0070] According to another aspect of the present invention, the present invention may also provide a film pasting method based on the film pasting equipment. Fig.13 FIG. 1 is a flow chart of a film pasting method 1300 of a film pasting device in the present invention. Fig.13 As shown, the method 1300 includes the following steps:

[0071] Step 1310: the transport platform 40 carries the conductive film 5 and moves forward.

[0072] Step 1320, when the conductive film 5 moves to the specified position, the rolling assembly 200 enters the clamping state from the initial state; specifically, based on the longitudinal position of the lead area 51 obtained by the film position positioning device 20 and the movement speed of the conductive film 5, it is determined whether the conductive film 5 moves to the specified position.

[0073] Step 1330 , driving the composite material strip 80 from the feeding mechanism 300 to move along the first guide surface 111 of the stripping mechanism body 110 toward the stripping edge 120 .

[0074] In step 1340, the composite material strip 80 is separated at the peeling edge into a base film 81 located on a side close to the peeling mechanism body and a pasting film 82 located on a side away from the peeling mechanism body.

[0075] In step 1350, the base film 81 is driven to move away from the peeling edge 120 along the second guide surface 112, and finally the base film is transferred to the return mechanism 400. Preferably, the composite material strip 80 is driven by the feeding mechanism and / or the return mechanism to move synchronously with the conductive film 5 on the transport platform 40, so that the film pasting effect is good, the film pasting is flat and there are no bubbles.

[0076] In step 1360 , the rolling assembly 200 rolls the separated film 82 onto the lead area of ​​the conductive film 5 in a compacted state.

[0077] Preferably, before the composite material strip 80 is fed into the stripping mechanism 100, the film on the composite material strip 82 is cut into film segments 82n of a predetermined length, and each time a film is pasted, one film segment 82n is pasted on the lead area of ​​the conductive film 5. More preferably, before the first pressing roller 210 enters the pressing state, the composite material strip 80 is fed into the stripping mechanism 100 for pre-stripping to obtain a film of the pre-stripping length, and after the first pressing roller 210 enters the pressing state, the composite material strip 80 is continuously fed into the stripping mechanism 100 for further stripping to obtain a film segment 82n of the remaining length of the predetermined length L.

[0078] For simplicity, the specific implementation of the film pasting method 1300 can refer to the relevant description of the film pasting device, which will not be repeated here.
