[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the embodiments in the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0031] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] The present application provides a double-layer film separation and conveying device, such as Figure 1 , Figure 2 As shown, it includes an unwinding component 100, a bottom film driving component 200 and a top film driving component 300. The unwinding component 100 includes an unwinding mechanism 110. The unwinding mechanism 110 is used to unwind the double-layer film that is bonded together. Specifically, the double-layer film includes a bottom film 10 and a top film 20. The top film 20 is non-sticky on both sides and is preferably a release film. The bottom film 10 includes a non-sticky first side and a sticky second side. The sticky second side of the bottom film 10 is bonded together with the top film 20 and wound on the unwinding shaft in the unwinding mechanism 110. In the double-layer film released in this embodiment, the top film 20 is on the top and the bottom film 10 is on the bottom. The side of the bottom film 10 facing downward is the non-sticky side. The adsorption table 210 below adsorbs the non-sticky side of the bottom film 10. The unwinding mechanism 110 includes an unwinding shaft and an unwinding motor connected to the unwinding shaft. The double-layer film is wound on the unwinding shaft. The unwinding motor provides a driving force to control the unwinding shaft to rotate and release the double-layer film material. It should be noted that in this application, the upper film of the double-layer film material is called the top film 20 and the lower film is called the bottom film 10. Figure 1 The viewing angle shown is also acceptable if the entire double-layer film separation and conveying device is turned upside down.

[0033] Among them, the bottom film driving component 200 and the top film driving component 300 can be considered to be located on the unwinding path of the unwinding mechanism 110 to separate the double-layer film. Specifically, the bottom film driving component 200 includes an adsorption table 210 and a first driving mechanism 220 connected to the adsorption table 210. The adsorption table 210 is used to adsorb and fix the bottom film 10 in the double-layer film from below. The first driving mechanism 220 drives the adsorption table 210 to move along the first direction. When the adsorption table 210 adsorbs film materials, it moves along the first direction with the film materials driven by the first driving mechanism 220. The film materials adsorbed by the adsorption table 210 can be either unseparated double-layer films or separated bottom films 10. The adsorption table 210 can reciprocate along the first direction. Figure 1 As shown, the first direction is, for example, Figure 1 The X-axis direction represents the up-down direction, and the Z-axis direction represents the up-down direction. The surface of the adsorption table 210 includes adsorption holes or adsorption channels, which are used to adsorb and fix the lower surface of the base film 10. The adsorption table 210 is provided with an adsorption cavity connected to the adsorption holes or adsorption channels on the adsorption table 210. The adsorption cavity is used to connect with the vacuum generating device to generate adsorption force. The first driving mechanism 220 can be a driving part such as a motor or a cylinder, preferably a motor. When the double-layer film needs to be separated, after the adsorption table 210 adsorbs and fixes the base film 10 from below, it moves along the first direction with the base film 10 driven by the first driving mechanism 220, which can not only separate the double-layer film, but also continue to move along the first direction with the base film 10 after the double-layer film is separated, and then perform subsequent actions.

[0034] The top film driving assembly 300 includes a top film driving member and a top film driving mechanism connected to the top film driving member, and the top film driving mechanism drives the top film driving member to move so as to drive the top film 20 to move in a direction away from the first direction. There are many forms of cooperation between the top film driving member and the top film driving mechanism. For example, the top film driving member is a reel for collecting the top film, and the top film driving mechanism is a reel motor, that is, the reel motor directly drives the reel to rotate so as to drive the top film 20 to move in a direction away from the first direction while being recovered on the reel (in order to facilitate the reel to drive the top film 20 to move better, two rollers can be set on the moving path to clamp the top film 20 between the two rollers). For another example, the top film 20 is driven to move in a direction away from the first direction by clamping the top film 20 between the top film driving member and the clamping member and driving the top film driving member to move. Specifically, the top film driving member and the clamping member can be the driving roller 320 and the clamping roller 330 described below, and the top film driving mechanism is a motor or a cylinder, which drives the driving roller 320 to rotate. Alternatively, the top film driving member and the clamping member are two clamping plates, and the top film driving mechanism drives the two clamping plates to clamp the top film 20 and move together, so that after the top film 20 is clamped, the top film 20 is driven by the top film driving mechanism 310 to move along a direction away from the first direction. The direction away from the first direction can be as follows: Figure 1 The arrows shown indicate the direction of apical membrane movement, which is Figure 1 The angle of view shown is obtuse to the first direction, so as to generate a component force in the horizontal direction opposite to the first direction, so that when the first drive mechanism 220 and the top film drive mechanism are working, they respectively generate forces in different directions on the top film 20 and the bottom film 10, so as to separate the two layers of film bonded together. The top film drive mechanism can be, for example, a cylinder, a linear module or a motor.

[0035] It should be noted that, in order to facilitate the separation of the double-layer film, the double-layer film of this embodiment has been partially pulled out at the beginning, and the free ends of the top film 20 and the bottom film 10 in the double-layer film that has been pulled out are partially separated. The free end of the separated bottom film 10 can be fixed on a structural member, for example, it can be fixed on the adsorption table 210, or it can be fixed on the film-absorbing member described below; and the free end of the top film 20 is fixed on the top film driving member (for example, it is wound and fixed on the winding shaft, or it is fixed between the driving roller 320 and the clamping roller 330 described below). In this embodiment, the relative positional relationship between the bottom film driving assembly 200 and the top film driving assembly 300 is not restricted, and the bottom film 10 of the released double-layer film can be adsorbed and fixed by the adsorption table 210 in the bottom film driving assembly 200, and the top film 20 in the double-layer film that has been pulled out in advance can be fixed by the top film driving assembly 300 and moved in a direction away from the first direction under the drive of the top film driving mechanism. The double-layer film separation and conveying device of this embodiment is particularly suitable for application scenarios in which double-layer film materials are separated and then one of the separated layers of the film is continuously conveyed and moved for processing.

[0036] The present application drives the adsorption table 210 through the first driving mechanism 220 and the top film driving mechanism to drive the top film driving member to move, thereby applying forces in different directions to the top film 20 and the bottom film 10, so that the double-layer films bonded together are quickly and smoothly separated, thereby facilitating the transportation and subsequent processing of film materials, especially sticky films.

[0037] Furthermore, the movement speed of the adsorption table 210 driven by the first driving mechanism 220 is the same as the movement speed of the top film driving member driven by the top film driving mechanism, thereby making the double-layer film separation process more stable.

[0038] Among them, the double-layer film separation and conveying device also includes an auxiliary separation member 400 arranged on the unwinding path of the unwinding mechanism 110. Along the unwinding direction of the unwinding mechanism 110, the bottom film driving component 200 and the top film driving component 300 are located behind the auxiliary separation member 400. The double-layer film released by the unwinding mechanism 110 passes through the bottom surface of the auxiliary separation member 400 and is separated at the end of the auxiliary separation member 400 (the end away from the unwinding mechanism 110, preferably the wedge 410 described below) by the driving of the bottom film driving component 200 and the top film driving component 200. The separated top film 20 is wound from the top of the end to the top film driving member (for example, between the driving roller 320 and the clamping roller 330 described below), and the bottom film 10 fixed on the adsorption table 210 is driven by the adsorption platform 210 to pass from under the end. It should be noted that a portion of the double-layer film is initially pulled out and first bypasses from the bottom of the auxiliary separation member 400, and then the top film 20 is separated from the bottom film 10 from the end, and the free end of the separated bottom film 10 is fixed to a structural member, while the free end of the top film 20 is fixed to the top film driving member. When the subsequent separation of the double-layer film is automatically performed, the unwinding mechanism 110 automatically releases a section of the double-layer film, and the released double-layer film also bypasses from the bottom of the auxiliary separation member 400, and then is automatically separated from the end under the drive of the first driving mechanism 220 and the top film driving mechanism 310. By setting the auxiliary separation member 400, the double-layer film can be fixed at the end of the auxiliary separation member 400 for separation, and the auxiliary double-layer film is separated smoothly and quickly.

[0039] When the first driving mechanism 220 drives the adsorption table 210 to move below the auxiliary separation member 400 to separate the double-layer film, a certain gap is maintained between the adsorption table 210 and the plane at the bottom of the auxiliary separation member 400 to facilitate separation of the double-layer film.

[0040] Furthermore, the bottom of the auxiliary separation member 400 is flat so as to smoothly absorb the double-layer film released from the unwinding mechanism 110, and the bottom of the auxiliary separation member 400 has a plurality of absorption holes, which are used to absorb the double-layer film so that the double-layer film is smoothly absorbed during the unwinding process and will not fall and generate wrinkles. The double-layer film released by the unwinding mechanism 110 passes through the auxiliary separation member 400 and then is separated by the bottom film driving assembly 200 and the top film driving assembly 300. Figure 3 for Figure 1 Preferably, the bottom surface of the auxiliary separator 400 is at the same height as the height of the adsorption table 210 when the double-layer film is adsorbed, so that the double-layer film remains flat and wrinkle-free during unwinding and separation.

[0041] As another example, Figure 1As shown, the unwinding assembly 100 also includes an unwinding support shaft 111 arranged on the unwinding path, the unwinding support shaft 111 is located in front of the auxiliary separator 400, the bottom height of the unwinding support shaft 111 is at the same height as the bottom height of the auxiliary separator 400, and the double-layer film released by the unwinding mechanism 110 bypasses the unwinding support shaft 111 and then passes through the auxiliary separator 400. By setting the unwinding support shaft 111, the double-layer film is smoothly unwound to the auxiliary separator 400, and the auxiliary double-layer film is not wrinkled during the unwinding process.

[0042] As another embodiment, the end of the auxiliary separation member 400 away from the unwinding mechanism 110 is configured in a wedge shape, such as Figure 1 The surface of the wedge 410 shown is inclined downward along the unwinding direction, that is, the wedge 410 is a descending wedge. The double-layer film unwound by the unwinding mechanism 110 passes under the auxiliary separation member 400 and is separated from the wedge 410. The separated top film 20 goes from the top of the wedge 410 to the top film driving member, and the bottom film 10 fixed on the adsorption table 210 is driven by the adsorption platform 210 to pass under the wedge 410. By setting the wedge 410 structure, the double-layer film is easier to separate.

[0043] During operation, the adsorption table 210 reaches the starting position of film pulling, at which time the double-layer film is adsorbed by the bottom of the auxiliary separation component 400, and the top film 20 of the separated part pulled out in advance of the double-layer film is clamped by the top film driving assembly 300 (the bottom film 10 of the separated part pulled out in advance of the double-layer film can be adsorbed and fixed by a structural member with an adsorption function), the adsorption table 210 turns on the vacuum to adsorb the bottom film 10 in the double-layer film that has not been separated, and at the same time the auxiliary separation component 400 turns off the vacuum (the structural member with the adsorption function turns off the vacuum), the first driving mechanism 220 works to move the adsorption table 210 rapidly along the first direction, while moving rapidly, the top film 20 is fixed by the top film driving assembly 300 and moves in a direction away from the first direction under the drive of the top film driving mechanism 310, the top film driving mechanism 310 is set to drive the top film 20 to move at a speed synchronized with the speed at which the first driving mechanism 220 moves with the adsorption table 210, and the double-layer film is separated at the wedge 410 at the end of the auxiliary separation component 400.

[0044] As another example, Figure 4 As shown, the unwinding assembly 100 also includes a mounting plate 120 and an unwinding buffer shaft 130 slidably connected to the mounting plate 120. By setting the unwinding buffer shaft 130, the unwinding buffer shaft 130 will slide on the mounting plate 120 (for example, along the direction of the unwinding buffer shaft 130) during the process of unwinding or film separation without unwinding. Figure 1The unwinding mechanism 110 slides up and down in the Z-axis direction as shown), so that the double-layer film will not be wrinkled during the unwinding process of the unwinding mechanism 110, and it can also ensure that the film will not be wrinkled during the high-speed film pulling process. The unwinding mechanism 110 is connected to the mounting plate 120. Specifically, there are many ways to slidably connect the unwinding buffer shaft 130 to the mounting plate 120, such as installing an unwinding buffer slide rail 140 on the mounting plate 120, and setting the unwinding buffer shaft 130 on the unwinding buffer slide rail 140, so that during the unwinding process, the unwinding buffer shaft 130 moves on the unwinding buffer slide rail 140 to make the double-layer film flat. More specifically, at this time, the unwinding buffer slide rail 140 is set in the vertical direction, and the unwinding buffer shaft 130 moves downward under the drive of the unwinding driving force.

[0045] Furthermore, two other support shafts are provided near the unwinding buffer shaft 130, for feeding the unwinding double-layer film material from the unwinding buffer shaft 130 and the support shaft according to the Figure 1 The sequence shown bypasses, thereby helping to support the double-layer film so that it does not wrinkle.

[0046] As another example, Figure 2 As shown, the top film driving member is a driving roller 320, and the top film driving mechanism is the top film driving mechanism 310 shown in the figure. The top film driving mechanism 310 is connected to the driving roller 320 through a belt. The top film driving assembly 300 also includes a clamping roller 330. The top film 20 in the double-layer film passes between the driving roller 320 and the clamping roller 330. The bottom film driving assembly 200 is located below the top film driving assembly 300. The top film driving mechanism 310 drives the driving roller 320 to rotate so that the top film 20 moves in a direction away from the first direction. The top film driving mechanism 310 of this embodiment can be a motor. When working, the top film driving mechanism 310 rotates with the driving roller 320. Since the driving roller 320 and the clamping roller 330 that are in contact with each other are both roller structures, the top film 20 clamped between the driving roller 320 and the clamping roller 330 moves in a direction away from the first direction under the driving force of rolling friction. This method of driving the top film 20 is simple and easy to implement, and the driving roller 320 and the clamping roller 330 do not move when the film is driven to move, so the working efficiency is higher.

[0047] As another example, Figure 2 As shown, the clamping roller 330 and the driving roller 320 are arranged in the up and down direction, and the top film driving component 300 also includes a lifting driving mechanism 340 connected to the clamping roller 330. In this embodiment, the lifting driving mechanism 340 can be, for example, a cylinder, which cooperates with the solenoid valve for reversing, so that the clamping roller 330 and the driving roller 320 are in a clamping state. After completing a film pulling, the clamping roller 330 is separated from the driving roller 320, and the top film 20 is released to eliminate the error caused by the asynchronous movement of the bottom film driving component 200 during the film pulling process, so as to avoid pulling the free end of the bottom film 10 and causing failure of separation of the double-layer film.

[0048] As another example, Figure 4 As shown, the unwinding assembly 100 also includes a mounting plate 120, a top film recovery mechanism 170 connected to the mounting plate 120 for recovering the top film 20 after separation, and a winding buffer shaft 180 slidably connected to the mounting plate 120, and the unwinding mechanism 110 is connected to the mounting plate 120. By providing the top film recovery mechanism 170, it is convenient to continue to use the top film 20 after recovery. Specifically, the top film recovery mechanism 170 includes a winding shaft and a winding motor connected to the winding shaft, and the winding motor provides a driving force to control the rotation of the winding shaft. By providing the winding buffer shaft 180, the top film 20 will not be wrinkled during the winding process, and it can also be ensured that the film will not be wrinkled during the high-speed film drawing process. Specifically, there are many ways to slidably connect the winding buffer shaft 180 to the mounting plate 120, such as installing a winding buffer slide rail on the mounting plate 120, and setting the winding buffer shaft 180 on the winding buffer slide rail, so that during the unwinding process, the winding buffer shaft 180 moves on the winding buffer slide rail to flatten the top film 20. More specifically, at this time, the winding buffer slide rail is set in the vertical direction.

[0049] As another embodiment, the bottom film driving assembly 200 is an interactive platform, which further includes a base, and two first driving mechanisms 220 arranged on both sides of the base, such as Figure 1 As shown, each first driving mechanism 220 is connected to at least one second driving mechanism 230, and the second driving mechanism 230 is connected to at least one adsorption table 210, and the second driving mechanism 230 moves up and down with the adsorption table. Specifically, taking each first driving mechanism 220 connected to one second driving mechanism 230, and the second driving mechanism 230 connected to two adsorption tables 210 as an example, a first driving mechanism 220 and a second driving mechanism 230 connected to the first driving mechanism 220 constitute a group of conveying mechanisms, and the bottom film driving assembly 200 has two groups of conveying mechanisms, and the two groups of conveying mechanisms work simultaneously. The two groups of conveying mechanisms move their respective adsorption tables 210 alternately in the first direction and / or the vertical direction, which can greatly improve the work efficiency, realize the rapid separation of the double-layer film, and the rapid movement of the separated bottom film. Among them, the first driving mechanism 220 and the second driving mechanism 230 can both be linear modules. Furthermore, a film material processing station and other stations can be set on the moving path of the conveying mechanism, and a film processing component can be set corresponding to the processing station. One conveying mechanism completes the processing of the film material, and the other conveying mechanism completes the subsequent work after the film processing (such as waste removal) and performs separation of the next section of double-layer film and other work (such as cutting of the separated bottom film).

[0050] As another example, Figure 5As shown, the double-layer film separation and conveying device further includes a cutting assembly 500 located behind the auxiliary separation member 400, and the cutting assembly 500 includes a cutting member 510 and a film absorbing member 520. The cutting member 210 is located above the adsorption table 210 and is used to cut the separated bottom film 10. The film absorbing member 520 is used to absorb and fix the free end of the bottom film 10 after the cutting member 510 cuts the bottom film 10 each time. The film absorbing member 520 is close to the cutting member 510, and the film absorbing member 520 is located between the auxiliary separation member 400 and the cutting member 510. By providing the cutting member 510, the separated bottom film 10 can be cut into sections, which is convenient for subsequent processing of the sections of the bottom film 20. The cutting member 510 cuts the bottom film 10 into sections for subsequent processing, which can improve the processing accuracy. Among them, the cutting piece 510 can be a cutter or a laser cutter. In this embodiment, it is a cutter. When performing the cutting work, the cutter can set the moving path of the cutter along the pattern to be cut. In order to make the cutter move, a cutter drive component, such as a motor or a cylinder, can be configured for the cutter. Among them, the film suction piece 520 can be a suction cup mechanism alone, or it can be adsorbed by setting an adsorption hole at the bottom of the film suction piece 520 as described below. By setting the film suction piece 520, the flexible bottom film 10 can be prevented from falling and deforming after the bottom film 10 is cut because it is not adsorbed and fixed, or from sticking to itself because of the stickiness of the surface. Furthermore, Figure 1 In the illustrated embodiment, the auxiliary separation member 400 is located between the top film driving assembly 300 and the cutting assembly 500.

[0051] As another example, Figure 6 As shown, a cutting groove 213 is provided near the end of the adsorption table 210 to prevent the adsorption table 210 from being damaged when the cutting piece 510 cuts the base film 10. When the cutting piece 510 is a cutting knife, the cutting knife can pass through the cutting groove 213 to avoid and not damage the adsorption table 210. When the cutting piece 510 is a laser, by providing the cutting groove 213, the laser beam emitted by the laser can be heated and cut at the cutting groove to prevent the heat of the laser from damaging the surface of the adsorption table 510 at the cutting position.

[0052] As another embodiment, the adsorption area of ​​the adsorption table 210 is divided into a first adsorption area and a second adsorption area with the cutting groove 213 as the boundary, and the first adsorption area and the second adsorption area can be controlled independently. Figure 6 As shown, the adsorption holes in the first adsorption area at the end of the adsorption table 210 are the first adsorption holes 211, and the adsorption holes in the second adsorption area in the middle are the second adsorption holes 212. The first adsorption area and the second adsorption area can be independently controlled, which means that the first adsorption hole 211 and the second adsorption hole 212 can independently control when to turn on and off the vacuum and control the vacuum value, so as to make the separation and cutting process of the double-layer film smoother.

[0053] As another example, Figure 5 As shown, the film absorbing member 520 also serves as a first clamping member, the bottom of the film absorbing member 520 is a plane, and adsorption holes are arranged at the bottom of the film absorbing member 520. The cutting assembly 500 also includes a clamping drive mechanism connected to the film absorbing member 520. The clamping drive mechanism drives the film absorbing member 520 to move up and down so as to choose whether to clamp the bottom film 10 according to demand. When the film absorbing member 520 also serves as the first clamping member, the bottom film 10 can be fixed on the adsorption table 210 by the film absorbing member 520 before cutting so as to facilitate better cutting. The film absorbing member 520 also serves as a clamping member, making the structure simpler.

[0054] As another embodiment, the cutting assembly 500 further includes a second pressing member, and the first pressing member and the second pressing member are located on both sides of the cutting member 510 along the first direction. Figure 5 The cutting piece 510 cuts the base film 10 along a direction (horizontally) perpendicular to the first direction. The cutting piece 510 is a cutting knife, and the cutting knife cuts linearly along the gap between the first pressing piece and the second pressing piece. By arranging pressing pieces on both sides of the cutting piece 510, the cutting effect is better.

[0055] Specific working process:

[0056] Driven by the first driving mechanism 220, the adsorption table 210 reaches the starting position of film pulling. At this time, the double-layer film is adsorbed by the auxiliary separation component 400, the top film 20 is clamped by the top film driving component 200, and the free end of the bottom film 10 is adsorbed and lifted by the film suction component 520; before the first driving mechanism 220 moves with the double-layer film, the unwinding shaft releases a section of double-layer film material, and the reeling shaft recovers the top film 20 in the section of double-layer film pulled out last time.

[0057] When pulling the film, the adsorption table 210 contacts the bottom of the bottom film 10 in the double-layer film, the adsorption table 210 turns on the vacuum (preferably, the first adsorption hole 211 and the second adsorption hole 212 turn on the vacuum at the same time), and the auxiliary separation component 400 turns off the vacuum and turns on the back blowing at the same time, the film suction component 520 presses down, the bottom film 10 is adsorbed by the adsorption table 210, the film suction component 520 turns off the vacuum and turns on the back blowing and lifts up, at this time the double-layer film is adsorbed by the adsorption table 210, and the first driving mechanism 220 drives the adsorption table 210 to move rapidly. During the rapid movement process, the bottom film 10 is always adsorbed on the adsorption table 210, and the adsorption table 210 is pulled forward rapidly. At the same time, the top film 20 is clamped and recovered by the top film driving assembly 300, requiring the top film 20 to be retracted. The speed at which the film driving mechanism 310 rotates to tighten the top film 20 is synchronized with the speed at which the first driving mechanism 220 drives the adsorption table 210 to move. The double-layer film is separated by the wedge 410 at the end of the auxiliary separation component 400 under the action of the bottom film driving component 200 and the top film driving component 300. The adsorption table 210 moves from the film pulling starting position to the film pulling end position to complete a film pulling. After reaching the position, the film suction component 520 presses down to press the bottom film 10 onto the adsorption table 210. At the same time, the film suction component 520 turns on the vacuum, and the cutting component 510 quickly cuts the film. The film suction component 520 turns on the vacuum, the first adsorption hole 211 turns off the vacuum and turns on backblowing, and the end of the bottom film 10 is sucked and lifted by the film suction component 520. In this way, a film pulling and cutting is completed.

[0058] The film material of the present application has no wrinkles during separation and transportation, which effectively improves the subsequent processing accuracy and product yield.

[0059] The present application also proposes a film processing device, including the double-layer film separation and conveying device described in any one of the above embodiments, and a film processing component located behind the cutting component 500 along the first direction, wherein the first driving mechanism 220 drives the adsorption table 210 to move to the processing station where the film processing component is located, and the film processing component processes the area to be processed on the cut bottom film. Specifically, the area to be processed here can be the portion corresponding to the bottom film 10 adsorbed by the second adsorption area of ​​the adsorption table 210 (after the cutting piece 510 cuts the bottom film 10 along the cutting groove, the bottom film 10 corresponding to the first adsorption area is adsorbed and lifted by the film adsorption piece 520, and the bottom film 10 corresponding to the second adsorption area is moved to the processing station by the adsorption table 210). After the double-layer film is separated by the film processing device, the adsorption platform 210 is driven to continue to move with the separated bottom film 10 to the processing station where the film processing component is located to continue processing the bottom film 10, and rapid conveying and processing are achieved while separating the double-layer film. Specifically, the film processing component can be set according to actual needs, for example, a laser processing component, which processes the bottom film 10 with a laser beam to obtain a desired pattern on the bottom film 10. Furthermore, the bottom film driving component 200 is preferably an interactive platform to improve production capacity.
