[0025] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] Currently, in the process of encapsulating photovoltaic modules, a light guide film strip needs to be attached to the back glass of the photovoltaic module using a gap film attaching equipment.

[0027] In related technologies, gap-applying film equipment typically includes a film stringing mechanism, a film stringing platform, a sheet-applying mechanism, and a sheet-applying platform. The film stringing platform is located below the film stringing mechanism and is used to support the back glass. The sheet-applying platform is located on one side of the film stringing platform and below the sheet-applying mechanism; it is also used to support the back glass. The film stringing mechanism is used to apply gap-applying film to the back glass, while the sheet-applying mechanism is used to apply sheet-to-sheet film to the back glass. The back glass can be pre-applied for sheet-to-sheet spacing, followed by the sheet-to-sheet layering.

[0028] Figure 1 This is a schematic diagram of the film-attaching mechanism in related technologies.

[0029] like Figure 1 As shown, the related technology has two film-applying mechanisms, which can be divided into a first film-applying mechanism 10 and a second film-applying mechanism 20, with the first film-applying mechanism 10 and the second film-applying mechanism 20 being distributed at intervals.

[0030] The first film-applying mechanism 10 includes a first support 11, a first film-applying head 12, a first unwinding assembly 13, a first drive assembly 14, and a first lifting assembly. The first film-applying head 12 is located at the lower part of the first support 11, and the first unwinding assembly 13 is located on one side of the first support 11. The first film-applying head 12 is used to apply film to the back glass, and the first unwinding assembly 13 is used to set the film reel corresponding to the first film-applying head 12. The first drive assembly 14 drives the first film-applying head 12 and the first unwinding assembly 13 to move horizontally, and the first lifting assembly drives the first film-applying head 12 and the first unwinding assembly 13 to move vertically. In the example of this application, the vertical direction is the Z-axis direction shown in the figure.

[0031] The second film application mechanism 20 includes a second support 21, a second film application head 22, a second unwinding assembly 23, a second drive assembly 24, and a second lifting assembly. The second film application head 22 is located at the lower part of the second support 21, and the second unwinding assembly 23 is located on one side of the second support 21. The second film application head 22 is used to apply film to the back glass, and the second unwinding assembly 23 is used to hold the film reel corresponding to the second film application head 22. The second drive assembly 24 drives the second film application head 22 and the second unwinding assembly 23 to move horizontally, and the second lifting assembly drives the second film application head 22 and the second unwinding assembly 23 to move vertically.

[0032] During the film application process, the first drive assembly 14 drives the first film application head 12 to move in the film application direction and apply the film, while the second drive assembly 24 drives the second film application head 22 to move in the same direction as the first film application head 12 and apply the film. The film application direction is the positive X-axis direction shown in the figure.

[0033] However, due to the film application pattern, the structural layout of the second film application mechanism 20 is opposite to that of the first film application mechanism 10. That is, the second unwinding assembly 23 is located on the side of the second support 21 facing the first support 11, and the second unwinding assembly 23 is located between the first support 11 and the second support 21. This means that when changing the film reel of the first unwinding assembly 13, it is necessary to enter the inside of the equipment, which makes the operation difficult and affects production efficiency.

[0034] On the other hand, the first lifting component in the related technology needs to drive the first string of film-applying heads 12 and the first unwinding component 13 to move in the vertical direction, and the second lifting component needs to drive the second string of film-applying heads 22 and the second unwinding component 23 to move in the vertical direction. This results in the first lifting component and the second lifting component having a large load and a relatively complex structure, which affects the production cost.

[0035] Therefore, this application provides a gap film application device, which has the technical advantages of facilitating the replacement of film reels and optimizing the internal structural layout of the device.

[0036] Figure 2 This is a schematic diagram of the gap film application device provided in this application. Figure 3 This is a schematic diagram of the planar layout of the gap film application device provided in this application.

[0037] like Figure 2 and Figure 3As shown, the gap laminating equipment includes a frame, two sets of laminating mechanisms, a laminating platform 400, a laminating conveyor line 500, a sheet laminating mechanism 700, a sheet laminating platform 800, and a sheet laminating conveyor line 900. The sheet laminating machine includes a sheet laminating frame 600. The frame includes a laminating frame 100 and a sheet laminating frame 600, which are detachably connected. The laminating mechanisms are housed within the laminating frame 100, and the sheet laminating mechanism 700 is housed within the sheet laminating frame 600. One set of laminating mechanisms is defined as the first laminating mechanism 200, and the other set is defined as the second laminating mechanism 300.

[0038] Specifically, the first film-applying mechanism 200, the second film-applying mechanism 300, the film-applying platform 400, and the film-applying conveyor line 500 are all disposed on the film-applying machine frame 100. A feeding port is formed on one side of the film-applying machine frame 100. The film-applying platform 400 and the film-applying conveyor line 500 are both disposed below the first film-applying mechanism 200 and the second film-applying mechanism 300. The film-applying conveyor line 500 is used to transport materials to the film-applying platform 400. The film-applying platform 400 is used to carry the materials. The first film-applying mechanism 200 and the second film-applying mechanism 300 are used to move along a first direction and apply film to the materials on the film-applying platform 400.

[0039] A sheet-applying frame 600 is positioned on the side of the string-applying frame 100 away from the feed inlet, and the side of the sheet-applying frame 600 away from the string-applying frame 100 forms the discharge inlet. A sheet-applying mechanism 700, a sheet-applying platform 800, and a sheet-applying conveyor line 900 are all located within the sheet-applying frame 600. Both the sheet-applying platform 800 and the sheet-applying conveyor line 900 are positioned below the sheet-applying mechanism 700. The sheet-applying conveyor line 900 is flush with the string-applying conveyor line 500 and is used to connect with the string-applying conveyor line 500, transporting the material to the sheet-applying platform 800. The sheet-applying platform 800 is used to hold the material. The sheet-applying mechanism 700 moves along a second direction and applies sheet-applying technology to the material on the sheet-applying platform 800. The second direction forms an angle with the first direction.

[0040] In the example of this application, the material can be the back glass of a photovoltaic module. The first direction is the string-mounting direction, and the second direction is the sheet-mounting direction, which are perpendicular to each other. The first direction is the X-axis direction shown in the figure, and the second direction is the Y-axis direction shown in the figure.

[0041] In some embodiments, the film-coating frame 100 has a first material changing area 101 and a second material changing area 102 formed on both sides in the first direction, and the first material changing area 101 and the second material changing area 102 are distributed at intervals in the first direction.

[0042] The first direction includes an opposite positive direction and a negative direction. For example, the positive direction is the positive X-axis direction in the diagram, and the negative direction is the negative X-axis direction in the diagram. Film application is performed when both the first film application mechanism 200 and the second film application mechanism 300 can move in the positive direction.

[0043] For ease of understanding, the following description uses a specific scenario to illustrate the film application method of the first film application mechanism 200 and the film reel replacement method of the second film application mechanism 300.

[0044] When it is necessary to apply film to materials, the first film application mechanism 200 is located in the middle of the film application platform 400, and the second film application mechanism 300 is located at one end of the film application platform 400 close to the second material changing area 102. At this time, the first film application mechanism 200 is located in the middle of the material, and the second film application mechanism 300 is located on one side of the material.

[0045] After the film application process begins, the first film application mechanism 200 and the second film application mechanism 300 move simultaneously in the forward direction, and the first film application mechanism 200 and the second film application mechanism 300 apply film in the forward direction while moving.

[0046] After the film is applied to the material, the first film application mechanism 200 moves to one end of the film application platform 400 near the first material changing area 101, and the second film application mechanism 300 moves to the middle of the film application platform 400. At this point, the first film application mechanism 200 is located on the other side of the material, and the second film application mechanism 300 is located in the middle of the material. Subsequently, the material can be transported to the sheet film conveyor line 900, and the first and second film application mechanisms 200 and 300 move and reset.

[0047] When the film reel of the first film application mechanism 200 needs to be replaced, the first film application mechanism 200 can move in the forward direction to the first material changing area 101. When the film reel of the second film application mechanism 300 needs to be replaced, the second film application mechanism 300 can move in the reverse direction to the second material changing area 102.

[0048] It is understandable that the first film application mechanism 200 and the second film application mechanism 300 can move in the same direction during the film application process to meet the film application pattern requirements corresponding to the material.

[0049] Figure 4 This is a first structural schematic diagram of the film laminating machine provided in this application.

[0050] like Figures 2 to 4As shown, each film application mechanism includes a support, a drive assembly, and one or more film application head unwinding assemblies. The drive assembly is connected to the support and the frame, and is used to drive the support to move along a first direction on the frame. One or more film application heads are disposed on the support, and are used to follow the movement of the support and perform film application. The unwinding assembly is disposed on the support, and is used to hold the film reel corresponding to the film application head.

[0051] The bracket, drive assembly, film application head, and unwinding assembly in the first film application mechanism 200 are respectively: first bracket 210, first drive assembly 220, first film application head 230, and first unwinding assembly 240.

[0052] The bracket, drive assembly, film application head, and unwinding assembly in the second film application mechanism 300 are respectively: second bracket 310, second drive assembly 320, second film application head 330, and second unwinding assembly 340.

[0053] The first set of film-applying heads 230 and the second set of film-applying heads 330 are respectively installed on opposite sides of the two supports, such that the first unwinding assembly 240 faces the first material changing area 101 and the second unwinding assembly 340 faces the second material changing area 102.

[0054] Specifically, the first film-applying mechanism 200 includes a first support 210, a first drive assembly 220, a first film-applying head 230, and a first unwinding assembly 240. The first drive assembly 220 is connected to the first support 210 and the film-applying machine frame 100, and is used to drive the first support 210 to move along a first direction on the film-applying machine frame 100.

[0055] The first film-applying head 230 is disposed on the first support 210 and moves synchronously with the first support 210. The first film-applying head 230 is used to follow the movement of the first support 210 and perform film application. The first unwinding assembly 240 is disposed on the side of the first support 210 facing the first material changing area 101 and moves synchronously with the first support 210. The first unwinding assembly 240 is used to set the film reel corresponding to the first film-applying head 230.

[0056] During the film application process, the material is supported on the film application platform 400. The first drive component 220 drives the first support 210 to move along the first direction, and drives the first film application head 230 and the first unwinding component 240 to move synchronously. The first film application head 230 can apply film to the material while moving.

[0057] When the film reel of the first unwinding assembly 240 needs to be replaced, the first drive assembly 220 drives the first support 210 to move along the first direction and moves the first unwinding assembly 240 to the first material changing area 101. At this time, the operator can replace the film reel of the first unwinding assembly 240 in the first material changing area 101 from the side of the film laminating machine frame 100.

[0058] In some embodiments, the second film-applying mechanism 300 includes a second support 310, a second drive assembly 320, a second film-applying head 330, and a second unwinding assembly 340. The second drive assembly 320 is connected to the second support 310 and the film-applying machine frame 100, and drives the second support 310 to move along a first direction on the film-applying machine frame 100. The second film-applying head 330 is disposed on the second support 310 and moves synchronously with it. The second film-applying head 330 follows the movement of the second support 310 and performs film applicating. The second unwinding assembly 340 is disposed on the side of the second support 310 facing the second material changing area 102 and moves synchronously with it. The second unwinding assembly 340 is used to position the film reel corresponding to the second film-applying head 330.

[0059] During the film application process, the material is supported on the film application platform 400. The second drive component 320 drives the second support 310 to move along the first direction, and drives the second film application head 330 and the second unwinding component 340 to move synchronously. The second film application head 330 can apply film to the material while moving.

[0060] When the film reel of the second unwinding assembly 340 needs to be replaced, the second drive assembly 320 drives the second support 310 to move along the first direction and moves the second unwinding assembly 340 to the second material changing area 102. At this time, the operator can replace the film reel of the second unwinding assembly 340 in the second material changing area 102 from the side of the film laminating machine frame 100.

[0061] It is understandable that the operator can be located on the side of the film laminating machine frame 100 and replace the film reel in the first unwinding assembly 240 in the first material changing area 101 or the second unwinding assembly 340 in the second material changing area 102 without having to enter the equipment. This makes the operation more convenient and improves the efficiency of film reel replacement and production efficiency.

[0062] In this embodiment, there is a gap between the first string of film-applying heads 230 and the second string of film-applying heads 330, and the gap is greater than or equal to the film-applying length.

[0063] When the first support 210 and the second support 310 move along the first direction, the first film-applying head 230 and the second film-applying head 330 move synchronously and apply film. Thus, the first film-applying mechanism 200 and the second film-applying mechanism 300 can move in the same direction during the film-applying process to meet the film-applying pattern requirements corresponding to the material.

[0064] Figure 5 for Figure 4 A partial enlarged view of point A in the middle. Figure 6 The diagram shows the structure of the first and second film application mechanisms provided in this application.

[0065] like Figures 4 to 6 As shown, in some embodiments, a baffle is provided on the side of the support away from the unwinding assembly, and the baffle and the support form a receiving cavity. Each unwinding assembly includes one or more unwinding rods and an unwinding drive, wherein one end of the unwinding rod passes through the receiving cavity and is rotatably connected to the support. The unwinding drive is disposed in the receiving cavity and connected to the unwinding rod, and the unwinding drive is used to drive the unwinding rod to rotate.

[0066] In some embodiments, the support has two or more support members on the side facing the unwinding assembly, each support member being slidably connected to the support. Each unwinding assembly also includes one or more unwinding rods, each unwinding rod being rotatably connected to a support member.

[0067] The first film application mechanism 200 includes a baffle 215, a receiving cavity 211, an unwinding rod 241, an unwinding drive 242, and a support 214.

[0068] Specifically, the first support 210 is in the shape of a hollow frame, and the first baffle 215 is bolted to the first support 210 to close one side of the first support 210 and to form a first receiving cavity 211 inside the first support 210. The first receiving cavity 211 is used to partially receive the first unwinding assembly 240.

[0069] The first support 210 is slidably connected to the film-applying machine frame 100 via a slide rail and slide table structure. The first baffle 215 is disposed on the side of the first support 210 facing the second support 310, and the first baffle 215 closes one side of the first receiving cavity 211 so that the opening of the first receiving cavity 211 is formed on the side of the first support 210 facing the first material changing area 101.

[0070] A first support member 214 is disposed at the opening of the first receiving cavity 211. The first support member 214 is elongated and extends along a third direction. In the example of this application, the third direction is the Z-axis direction shown in the figure. Both ends of the first support member 214 are slidably connected to the first bracket 210 through a slide rail and slide table structure, and the sliding direction is parallel to the first direction.

[0071] In some embodiments, the first unwinding assembly 240 includes one or more first unwinding rods 241 and first unwinding drive members 242. The first unwinding rods 241 are disposed on the side of the first support 210 facing the first material changing area 101 and are rotatably connected to the first support 210. The first unwinding rods 241 perform unwinding and winding functions by rotation. The first unwinding drive members 242 are disposed within the first receiving cavity 211 and connected to the first unwinding rods 241. The first unwinding drive members 242 are used to drive the first unwinding rods 241 to rotate.

[0072] For example, the first unwinding drive 242 is a servo motor, which has a body and an output shaft. The body of the first unwinding drive 242 is bolted and fixed inside the first receiving cavity 211, and the output shaft of the first unwinding drive 242 is positioned facing the opening of the first receiving cavity 211. A bearing sleeve is provided in the middle of the first support member 214. The first unwinding rod 241 extends along a first direction, one end of the first unwinding rod 241 passes through the bearing sleeve and enters the first receiving cavity 211, and is connected to the output shaft of the first unwinding drive 242 via a coupling; the other end of the first unwinding rod 241 protrudes from the first receiving cavity 211 and is used to set the film reel.

[0073] By placing the first unwinding drive 242 inside the first receiving cavity 211, the space occupied by the first unwinding drive 242 on the side of the first support 210 facing the second support 310 can be reduced. This reduces the minimum distance between the first support 210 and the second support 310, making it easier to control the movement position of the first support 210 and the second support 310.

[0074] By placing the first unwinding rod 241 outside the first receiving cavity 211, the position of the first unwinding rod 241 can be close to the first material changing area 101, making it convenient for the staff to replace the film reel with the first unwinding rod 241.

[0075] Figure 7 This is a schematic diagram of the structure of the first series of film-applying heads provided in this application.

[0076] like Figures 4 to 7 As shown, in some embodiments, the first film applicator 230 and the second film applicator 330 are both used to guide, cut, heat, and apply the film strip to achieve film application.

[0077] Both the first and second film-applying heads 230 and 330 include a blade holder, a pressure roller, and a cutter. The blade holder is fixedly or movably connected to a bracket. The pressure roller is rotatably connected to the bottom end of the blade holder and is configured to press the film strip. The cutter is movably connected to the bottom end of the blade holder and is configured to cut the film strip. The direction of film application is defined as the front, and the cutter is located in front of the pressure roller.

[0078] Specifically, the blade holder, pressure roller, and cutter in the first film application head 230 are respectively: a first blade holder 231, a first pressure roller 235, and a first cutter 237. The first blade holder 231 is fixedly or movably connected to the first bracket 210. The first pressure roller 235 is rotatably connected to the bottom end of the first blade holder 231, and the first cutter 237 is movably connected to the bottom end of the first blade holder 231, and the first cutter 237 is located in front of the first pressure roller 235.

[0079] For example, a first connecting plate 234 is provided on one side of the first tool holder 231, and the first connecting plate 234 is bolted and fixed to the first support member 214. The first tool holder 231 is provided with a first hot air pipe, a first conveying seat 236, and a plurality of first tensioning rollers 232, which are rotatably connected to the first tool holder 231. The first conveying seat 236 is provided with a conveying channel, through which the membrane belt is guided and limited. The first hot air pipe is used to heat the membrane belt.

[0080] In this embodiment, the first film-applying head 230 is used to follow the first support 210 and apply film when the first support 210 is in the forward direction. Specifically, the first pressure roller 235 and the first conveyor seat 236 are spaced apart in the forward direction, so that the first film-applying head 230 applies film in the forward direction.

[0081] It is worth noting that the number of the first string of film-applying heads 230 and the first unwinding rod 241 can be configured according to the actual situation. For example, in the example of this application, the first string of film-applying heads 230 can be set to 7 groups. The 7 groups of first string of film-applying heads 230 can be used to apply film to the gaps and edges of the photovoltaic module composed of 6 strings of cells. In other embodiments, the number of the first string of film-applying heads 230 and the first unwinding rod 241 can be adaptively adjusted according to the actual situation. This application does not limit this.

[0082] In some embodiments, the first film-applying mechanism 200 further includes a first translation component, which is disposed on the first support 210 and connected to the first unwinding assembly 240 and the first film-applying head 230. The first translation component is used to drive the first unwinding assembly 240 and the first film-applying head 230 to move in a second direction, thereby adjusting the position of the first unwinding assembly 240 and the first film-applying head 230 in the second direction and realizing the control of the film-applying spacing.

[0083] For example, the first translation assembly includes a first translation rack, a first translation member, and a first translation gear. The first translation rack extends along a second direction. The first translation member is a servo motor, having a body and an output shaft. The body of the first translation member is bolted to the upper end of the first tool holder 231. The output shaft of the first translation member passes through a first connecting plate 234 and is keyed to the first translation gear. The first translation gear meshes with the first translation rack for transmission. Thus, the first translation member can drive the first translation gear to rotate, thereby moving the first tool holder 231 and the first support member 214 in the second direction, achieving positional adjustment of the first unwinding assembly 240 and the first film-applying head 230 in the second direction.

[0084] Figure 8 This is a schematic diagram of the second structure of the film applicator provided in this application.

[0085] like Figure 4 , Figure 5 and Figure 8 As shown, in some embodiments, each drive assembly includes a drive rack, a drive gear, and a rotary drive member. The drive rack is fixed to the frame and extends along a first direction. The drive gear meshes with the drive rack for transmission. The rotary drive member is fixed to the bracket and connected to the drive gear, and is used to drive the drive gear to rotate.

[0086] The drive rack, drive gear, and rotary drive component in the first drive assembly 220 are respectively: first drive rack 221, first drive gear 222, and first drive component 223.

[0087] The first drive rack 221 is fixed to the first bracket 210 and extends along the first direction. The first drive gear 222 meshes with the first drive rack 221 for transmission. The first drive member 223 is fixed to the first bracket 210 and connected to the first drive gear 222. The first drive member 223 is used to drive the first drive gear 222 to rotate.

[0088] For example, the first drive rack 221 is bolted to the side of the film-applying machine frame 100. The first drive component 223 is a servo motor, which has a body and an output shaft. The body of the first drive component 223 is bolted to the lower part of the first bracket 210, and the output shaft of the first drive component 223 is arranged downward and keyed to the first drive gear 222. In this way, the first drive component 223 can drive the first drive gear 222 to rotate, thereby moving the first bracket 210 along a first direction.

[0089] In some embodiments, the number of first drive components 220 is two, and the two first drive components 220 are respectively disposed on both sides of the film application frame 100 in the second direction. The two first drive components 220 jointly drive the first support 210 to move, thereby improving the movement stability of the first support 210.

[0090] Figure 9 for Figure 8 A magnified view of a section at point B in the middle.

[0091] like Figure 6 , Figure 8 and Figure 9 As shown, in some embodiments, the baffle, receiving cavity, unwinding rod, unwinding drive and support in the second film application mechanism 300 are respectively: second baffle 315, second receiving cavity 311, second unwinding rod 341, second unwinding drive 342 and second support 314.

[0092] Specifically, the second support 310 is in the shape of a hollow frame, and the second baffle 315 is bolted to the second support 310 to close one side of the second support 310 and form a second receiving cavity 311 inside the second support 310. The second receiving cavity 311 is used to partially receive the second unwinding assembly 340.

[0093] The second support 310 is slidably connected to the film-applying machine frame 100 via a slide rail and slide table structure. The second baffle 315 is disposed on the side of the second support 310 facing the first support 210, and the second baffle 315 closes one side of the second receiving cavity 311 so that the opening of the second receiving cavity 311 is formed on the side of the second support 310 facing the second material changing area 102.

[0094] The second support member 314 is disposed at the opening of the second receiving cavity 311. The second support member 314 is in the shape of a long strip and extends along a third direction. Both ends of the second support member 314 are slidably connected to the second bracket 310 through a slide rail and slide table structure, and the sliding direction is parallel to the first direction.

[0095] In some embodiments, the second unwinding assembly 340 includes one or more second unwinding rods 341 and a second unwinding drive member 342. The second unwinding rod 341 is disposed on the side of the second support 310 facing the second material changing area 102 and is rotatably connected to the second support 310. The second unwinding rod 341 performs the unwinding and winding functions by rotation. The second unwinding drive member 342 is disposed within the second receiving cavity 311 and connected to the second unwinding rod 341. The second unwinding drive member 342 is used to drive the second unwinding rod 341 to rotate.

[0096] For example, the second unwinding drive 342 is a servo motor, which has a body and an output shaft. The body of the second unwinding drive 342 is bolted and fixed inside the second receiving cavity 311, and the output shaft of the second unwinding drive 342 is positioned facing the opening of the second receiving cavity 311. A bearing sleeve is provided in the middle of the second support member 314. The second unwinding rod 341 extends along a first direction, with one end of the second unwinding rod 341 passing through the bearing sleeve into the second receiving cavity 311 and connected to the output shaft of the second unwinding drive 342 via a coupling; the other end of the second unwinding rod 341 protrudes from the second receiving cavity 311 and is used to mount the film reel.

[0097] By placing the second unwinding drive 342 inside the second receiving cavity 311, the space occupied by the second unwinding drive 342 on the side of the second bracket 310 facing the first bracket 210 can be reduced. This reduces the minimum distance between the first bracket 210 and the second bracket 310, making it easier to adjust the movement position of the first bracket 210 and the second bracket 310.

[0098] By placing the second unwinding rod 341 outside the second receiving cavity 311, the position of the second unwinding rod 341 can be close to the second material changing area 102, making it convenient for staff to replace the film reel with the second unwinding rod 341.

[0099] Figure 10 This is a schematic diagram of the structure of the second series of film-applying heads provided in this application.

[0100] like Figures 8 to 10 As shown, in some embodiments, the blade holder, pressure roller, and cutter in the second film applicator 330 are respectively: a second blade holder 331, a second pressure roller 335, and a second cutter 337. The second blade holder 331 is fixedly or movably connected to the second support 310. The second pressure roller 335 is rotatably connected to the bottom end of the second blade holder 331, and the second cutter 337 is movably connected to the bottom end of the second blade holder 331, and the second cutter 337 is disposed on the front side of the second pressure roller 335.

[0101] For example, a second connecting plate 334 is provided on one side of the second cutter holder 331, and the second connecting plate 334 is bolted and fixed to the second support member 314. The second cutter holder 331 is provided with a second hot air pipe, a second conveyor seat 336, and a plurality of second tensioning rollers 332, which are rotatably connected to the second cutter holder 331. The second conveyor seat 336 is provided with a conveying channel, through which the membrane belt is guided and limited. The second hot air pipe is used to heat the membrane belt.

[0102] In this embodiment, the second film-applying head 330 is used to follow the second support 310 and apply film when the second support 310 is in the forward direction. Specifically, the second pressure roller 335 and the second conveyor seat 336 are spaced apart in the forward direction, thus enabling the second film-applying head 330 to apply film in the forward direction.

[0103] In some embodiments, the second film-applying mechanism 300 further includes a second translation component, which is disposed on the second support 310 and connected to the second unwinding assembly 340 and the second film-applying head 330. The second translation component is used to drive the second unwinding assembly 340 and the second film-applying head 330 to move along a first direction, thereby adjusting the position of the second unwinding assembly 340 and the second film-applying head 330 in the first direction and realizing the control of the film-applying spacing.

[0104] For example, the second translation assembly includes a second translation rack, a second translation member, and a second translation gear. The second translation rack extends along a first direction. The second translation member is a servo motor, having a body and an output shaft. The body of the second translation member is bolted to the upper end of the second tool holder 331. The output shaft of the second translation member passes through a second connecting plate 334 and is keyed to the second translation gear. The second translation gear meshes with the second translation rack for transmission. Thus, the second translation member can drive the second translation gear to rotate, thereby moving the second tool holder 331 and the second support member 314 in the first direction, achieving positional adjustment of the second unwinding assembly 340 and the second film-applying head 330 in the first direction.

[0105] like Figure 4 , Figure 6 , Figure 8 and Figure 9 As shown, in some embodiments, the drive rack, drive gear, and rotary drive member in the second drive assembly 320 are respectively: second drive rack 321, second drive gear (not shown in the figure), and second drive member 323.

[0106] The second drive rack 321 is fixed to the second bracket 310 and extends along the first direction. The second drive gear meshes with the second drive rack 321 for transmission. The second drive member 323 is fixed to the second bracket 310 and connected to the second drive gear. The second drive member 323 is used to drive the second drive gear to rotate.

[0107] For example, the second drive rack 321 shares the same rack as the first drive rack 221. The second drive member 323 is a servo motor, which has a body and an output shaft. The body of the second drive member 323 is bolted to the lower part of the second bracket 310, and the output shaft of the second drive member 323 is arranged downward and keyed to the second drive gear. In this way, the second drive member 323 can drive the second drive gear to rotate, thereby moving the second bracket 310 along the first direction.

[0108] In some embodiments, the number of second drive components 320 is two, and the two second drive components 320 are respectively disposed on both sides of the film application frame 100 in the second direction. The two second drive components 320 jointly drive the second support 310 to move, thereby improving the movement stability of the second support 310.

[0109] Figure 11 This is a schematic diagram of the structure of the film bonding platform provided in this application.

[0110] like Figure 4 and Figure 11 As shown, in some embodiments, the film-laying platform 400 includes a film-laying carrier 410 and a film-laying lifting assembly 420. The film-laying carrier 410 is located below the first film-laying mechanism 200 and the second film-laying mechanism 300, and a film-laying bearing area is formed above the film-laying carrier 410. The film-laying carrier 410 is capable of bearing material located in the film-laying bearing area. The film-laying lifting assembly 420 is connected to the film-laying carrier 410. The film-laying lifting assembly 420 is used to drive the film-laying carrier 410 to move vertically.

[0111] It is understood that when the material is carried on the film-coating platform 410, the film-coating lifting component 420 can drive the film-coating platform 410 to lift and lower, thereby driving the material to lift and lower, and realizing the function of the material moving up and down relative to the first film-coating mechanism 200 and the second film-coating mechanism 300.

[0112] Thus, the first film-applying mechanism 200 or the second film-applying mechanism 300 does not need to be equipped with an additional lifting structure, which simplifies the structural layout of the first film-applying mechanism 200 and the second film-applying mechanism 300, reduces the load on the first film-applying mechanism 200 and the second film-applying mechanism 300, and reduces production costs. At the same time, it can simplify the hardware layout of the first support 210 and the second support 310, reduce the thickness of the first support 210 and the second support 310 in the first direction, and reduce the minimum distance between the first support 210 and the second support 310, which facilitates the adjustment of the moving position of the first support 210 and the second support 310.

[0113] In some embodiments, the film-laying platform 410 includes a carrier plate 411 and a base frame 412. The carrier plate 411 is used to carry materials and is provided with a plurality of first through slots 413, which penetrate the carrier plate 411 vertically. The base frame 412 is fixed to the bottom surface of the carrier plate 411 and is connected to the film-laying lifting assembly 420. The base frame 412 is used to support the carrier plate 411.

[0114] In some embodiments, the film-applying lifting assembly 420 includes a film-applying lifter 421 and a film-applying lift drive 422. The film-applying lifter 421 is a worm gear screw type lifter, having a drive shaft 423 and a lifting rod 424. The drive shaft 423 of the film-applying lifter 421 is connected to a base frame 412 and extends vertically. The film-applying lift drive 422 is connected to the lifting rod 424 of the film-applying lifter 421 and is used to drive the lifting rod 424 of the film-applying lifter 421 to rotate.

[0115] For example, the film-laying lifting drive 422 is a servo motor, which has a body and an output shaft. The body of the film-laying lifting drive 422 can be fixed to a fixed object such as a base, and the output shaft of the film-laying lifting drive 422 is connected to the lifting rod 424 of the film-laying lifter 421.

[0116] Thus, the film-laying lifting drive 422 can drive the drive shaft 423 of the film-laying lift 421 to rotate, and use a worm gear screw drive to drive the lifting rod 424 of the film-laying lift 421 to rise and fall, thereby driving the film-laying platform 410 to rise and fall. It can be understood that the worm gear screw structure has the characteristics of anti-reverse rotation and high adjustment precision, which can improve the stability of the lifting action of the film-laying platform 410.

[0117] It is understood that in the example of this application, the film-laying lifter 421 adopts a worm gear screw type lifter. In other embodiments, the film-laying lifter 421 may also adopt a gear column type lifter, as long as it can achieve the effect of driving the film-laying platform 410 to rise and fall. This application does not impose any restrictions on this.

[0118] In some embodiments, the film-laying lifting assembly 420 further includes a film-laying coupling 425. Multiple film-laying lifters 421 are distributed at intervals, and the worm gear portions of the multiple film-laying lifters 421 are respectively connected to the film-laying platform 410. For example, the film-laying lifters 421 are distributed at the four corners of the film-laying platform 410, and the film-laying lifting drive members 422 are respectively connected to the drive shafts 423 of the multiple film-laying lifters 421 via the film-laying couplings 425.

[0119] Thus, the film-laying lifting drive 422 can simultaneously drive multiple film-laying lifters 421 through the film-laying coupling 425, so that multiple film-laying lifters 421 can simultaneously support the lifting of the film-laying platform 410 from the four corners of the film-laying platform 410, thereby improving the smoothness of the movement of the film-laying platform 410.

[0120] like Figure 3 , Figure 4 and Figure 11 As shown, in some embodiments, the film-laying conveyor line 500 is located below the film-laying mechanism and is arranged along the film-laying direction.

[0121] The film-coating conveyor line 500 includes multiple film-coating synchronous belts 501, each extending along a second direction, and the multiple film-coating synchronous belts 501 are spaced apart in a first direction. During material conveying, the multiple film-coating synchronous belts 501 simultaneously carry the material and drive it to move along the second direction.

[0122] In this embodiment, a film-laying platform 410 is disposed between multiple film-laying timing belts 501, and multiple first through slots 413 are formed through the platform 410 corresponding to the timing belts 501. For example, a carrier plate 411 can be accommodated between two adjacent film-laying timing belts 501. When the platform 410 rises and falls, the timing belts 501 can pass through the first through slots 413 of the carrier plate 411, allowing the carrier plate 411 to pass vertically between the multiple film-laying timing belts 501.

[0123] Specifically, the film-laying platform 410 has a first height and a second height, and the film-laying lifting assembly 420 can drive the film-laying platform 410 to move to the first height or the second height. When the film-laying platform 410 is at the first height, the height of the upper surface of the film-laying platform 410 is higher than the height of the upper surface of the film-laying timing belt 501. When the film-laying platform 410 is at the second height, the height of the upper surface of the film-laying platform 410 is lower than the height of the upper surface of the film-laying timing belt 501.

[0124] When multiple film-coating timing belts 501 move the material above the film-coating platform 410, the film-coating lifting assembly 420 can drive the film-coating platform 410 to rise to a first height, so that the material is supported on the film-coating platform 410 and detached from the multiple film-coating timing belts 501.

[0125] When the film-coating platform 410 is carrying materials, the film-coating lifting assembly 420 can drive the film-coating platform 410 to descend to a second height so that the materials are carried on multiple film-coating synchronous belts 501 and detached from the film-coating platform 410.

[0126] It is understood that when materials need to be laminated, the laminating platform 410 is initially positioned at a second height, and multiple laminating synchronous belts 501 transport the materials to above the laminating platform 410. Then, the laminating lifting assembly 420 can drive the laminating platform 410 to rise to a first height, lifting the materials from the multiple laminating synchronous belts 501 for laminating by the first laminating mechanism 200 and the second laminating mechanism 300. After laminating the materials, the laminating lifting assembly 420 can drive the laminating platform 410 to descend to a second height, repositioning the materials onto the multiple laminating synchronous belts 501 and removing them from the laminating platform 410. Then, the multiple laminating synchronous belts 501 continue to transport the materials. Thus, by utilizing the lifting function of the laminating platform 410, material transfer between the laminating platform 410 and the multiple laminating synchronous belts 501 can be achieved, improving work efficiency.

[0127] Figure 12 This is a schematic diagram of the structure of the film-attaching platform, the film-attaching timing belt, and the film-attaching alignment mechanism provided in this application.

[0128] like Figure 12 As shown, in some embodiments, the gap film application device further includes multiple sets of film application alignment mechanisms, all of which are connected to the film application platform 410.

[0129] Each film-attaching alignment mechanism includes a film-attaching reference alignment component, a film-attaching auxiliary alignment component, and a film-attaching alignment drive component. The reference alignment component and the auxiliary alignment component are located on opposite sides of the film-attaching bearing area. The film-attaching alignment drive component is connected to the reference alignment component and the auxiliary alignment component, and is used to drive the reference alignment component and the auxiliary alignment component to move closer to or further apart from each other.

[0130] Thus, when the material is carried on the film-coating platform 410, the film-coating alignment drive assembly can drive the film-coating reference alignment assembly and the film-coating auxiliary alignment assembly to move closer to each other, so that the film-coating reference alignment assembly and the film-coating auxiliary alignment assembly cooperate to hold against the opposite sides of the material, thereby aligning the material.

[0131] In one set of film-attachment alignment mechanisms, the film-attachment reference alignment component, the film-attachment auxiliary alignment component, and the film-attachment alignment drive component are defined as the first film-attachment reference alignment component 1300, the first film-attachment auxiliary alignment component 1400, and the first film-attachment alignment drive component 2100, respectively. In another set of film-attachment alignment mechanisms, the film-attachment reference alignment component, the film-attachment auxiliary alignment component, and the film-attachment alignment drive component are defined as the second film-attachment reference alignment component 1500, the second film-attachment auxiliary alignment component 1600, and the second film-attachment alignment drive component 2200, respectively.

[0132] The first string of film application reference alignment components 1300 and the first string of film application auxiliary alignment components 1400 are spaced apart along a first direction. The second string of film application reference alignment components 1500 and the second string of film application auxiliary alignment components 1600 are spaced apart along a second direction.

[0133] Thus, the first set of film-applying reference alignment components 1300 and the first set of film-applying auxiliary alignment components 1400 can align the material in the first direction, and the second set of film-applying reference alignment components 1500 and the second set of film-applying auxiliary alignment components 1600 can align the material in the second direction, ensuring that the material does not deviate from its position.

[0134] Figure 13 This is a structural diagram of the base frame and film-adhesive alignment mechanism provided in this application.

[0135] like Figure 12 and Figure 13 As shown, in some embodiments, the film-mounting reference alignment assembly includes a reference alignment base and reference alignment rollers, wherein the reference alignment base is connected to the film-mounting alignment drive assembly. The reference alignment rollers are connected to the reference alignment base.

[0136] In some embodiments, the film-mounted reference alignment assembly further includes a reference alignment lifting member, which is fixed to the reference alignment base and connected to the reference alignment roller. The reference alignment lifting member is used to drive the reference alignment roller to move up and down.

[0137] The film-laying stage 410 is provided with a reference alignment groove. When the reference alignment roller descends, it can enter the lower part of the film-laying stage 410; when the reference alignment roller rises, it is exposed above the film-laying stage 410 through the reference alignment groove and can slide within the groove.

[0138] The reference alignment base, reference alignment roller, and reference alignment lifting component in the first film-applying reference alignment assembly 1300 are respectively: first reference alignment base 1310, first reference alignment roller 1320, and first reference alignment lifting component 1330. The reference alignment groove corresponding to the film-applying reference alignment assembly is the first reference alignment groove 414.

[0139] Specifically, the first reference alignment base 1310 is connected to the first film-applying alignment drive assembly 2100, the first reference alignment lifting member 1330 is fixed to the first reference alignment base 1310, and the first reference alignment lifting member 1330 is connected to the first reference alignment roller 1320.

[0140] For example, the first string of film-applying alignment drive assembly 2100 includes a first string of film-applying reference drive member 2110, which is a cylinder with a piston rod. The first string of film-applying reference drive member 2110 is fixed relative to the base frame 412. A first reference alignment base 1310 is bolted to the piston rod of the first string of film-applying reference drive member 2110. A first reference alignment lifting member 1330 is a cylinder with a piston rod. The first reference alignment lifting member 1330 is bolted to the bottom surface of the first reference alignment base 1310, and the piston rod of the first reference alignment lifting member 1330 extends upward through the first reference alignment base 1310. A first reference alignment roller 1320 is rotatably disposed on the piston rod of the first reference alignment lifting member 1330.

[0141] When the first reference alignment roller 1320 descends, it can enter below the film-coating platform 410. At this time, the first reference alignment roller 1320 does not obstruct the material transport path.

[0142] When the first reference alignment roller 1320 rises, it is exposed above the film-laying platform 410 through the first reference alignment groove 414. At this time, the first reference alignment roller 1320 blocks the material transport path, and under the drive of the first film-laying reference drive unit 2110, the first reference alignment roller 1320 can slide in the first reference alignment groove 414.

[0143] In some embodiments, the film-attaching auxiliary alignment component includes an auxiliary alignment base, an auxiliary alignment platform, auxiliary alignment rollers, and an auxiliary alignment spring. The auxiliary alignment base is connected to the film-attaching alignment drive component. The auxiliary alignment platform is slidably connected to the auxiliary alignment base. The auxiliary alignment rollers are connected to the auxiliary alignment platform, and the auxiliary alignment rollers are spaced apart from the reference alignment rollers, with the spacing direction consistent with the sliding direction of the auxiliary alignment platform. The auxiliary alignment spring is disposed between the auxiliary alignment base and the auxiliary alignment platform, and is used to push the auxiliary alignment platform to slide.

[0144] In some embodiments, the film-attaching auxiliary alignment component further includes an auxiliary alignment lifting member, which is fixed to the auxiliary alignment table and connected to the auxiliary alignment roller. The auxiliary alignment lifting member is used to drive the auxiliary alignment roller to move up and down.

[0145] The film-laying stage 410 is provided with an auxiliary alignment groove. When the auxiliary alignment roller descends, it can enter the lower part of the film-laying stage 410; when the auxiliary alignment roller rises, it is exposed above the film-laying stage 410 through the auxiliary alignment groove and can slide within the groove.

[0146] Among them, the auxiliary alignment base, auxiliary alignment platform, auxiliary alignment roller, auxiliary alignment elastic component and auxiliary alignment lifting component in the first film-applying auxiliary alignment component 1400 are respectively: first auxiliary alignment base 1410, first auxiliary alignment platform 1420, first auxiliary alignment roller 1430, first auxiliary alignment elastic component 1440 and first auxiliary alignment lifting component 1450.

[0147] Specifically, the first auxiliary alignment base 1410 is connected to the first film-applying alignment drive assembly 2100, and the first auxiliary alignment platform 1420 is slidably connected to the first auxiliary alignment base 1410. The first auxiliary alignment lifting member 1450 is fixed to the first auxiliary alignment platform 1420, and the first auxiliary alignment lifting member 1450 is connected to the first auxiliary alignment roller 1430.

[0148] The first auxiliary alignment roller 1430 and the first reference alignment roller 1320 are spaced apart along the first direction. The first auxiliary alignment elastic member 1440 is disposed between the first auxiliary alignment base 1410 and the first auxiliary alignment platform 1420, and the first auxiliary alignment elastic member 1440 is used to push the first auxiliary alignment platform 1420 to move closer to the first reference alignment roller 1320 along the first direction.

[0149] For example, the first film-applying alignment drive assembly 2100 includes a first film-applying auxiliary drive component 2120, which is a motor screw mechanism with a translation stage. The first film-applying auxiliary drive component 2120 is fixed relative to the base frame 412. The first auxiliary alignment base 1410 is bolted to the translation stage of the first film-applying auxiliary drive component 2120. The first auxiliary alignment platform 1420 is slidably connected to the upper side of the first auxiliary alignment base 1410. The first auxiliary alignment elastic component 1440 is a telescopic spring component, which abuts against the side of the first auxiliary alignment platform 1420 opposite to the first reference alignment base 1310.

[0150] The first auxiliary alignment lifting component 1450 is a cylinder with a piston rod. The first auxiliary alignment lifting component 1450 is bolted to the bottom surface of the first auxiliary alignment platform 1420, and the piston rod of the first auxiliary alignment lifting component 1450 extends upward through the first auxiliary alignment platform 1420. The first auxiliary alignment roller 1430 is rotatably mounted on the piston rod of the first auxiliary alignment lifting component 1450.

[0151] When the first auxiliary alignment roller 1430 descends, it can enter below the film-coating platform 410. At this time, the first reference alignment roller 1320 does not obstruct the material transport path.

[0152] When the first auxiliary alignment roller 1430 rises, it is exposed above the film-laying platform 410 through the first auxiliary alignment groove 416. At this time, the first auxiliary alignment roller 1430 blocks the material transport path, and under the drive of the first film-laying auxiliary drive component 2120, the first auxiliary alignment roller 1430 can slide in the first auxiliary alignment groove 416.

[0153] It is understood that when the material needs to be aligned along the first direction, the first set of film-applying reference driving components 2110 drives the first reference alignment base 1310 to move, and the first set of film-applying auxiliary driving components 2120 drives the first auxiliary alignment base 1410 to move, so that the first reference alignment roller 1320 and the first auxiliary alignment roller 1430 respectively abut against the opposite sides of the material in the first direction to achieve the alignment effect. Furthermore, during the process of the first auxiliary alignment roller 1430 abutting against the material, the first auxiliary alignment roller 1430 and the first auxiliary alignment platform 1420 can rebound under the action of the first auxiliary alignment elastic component 1440, which not only achieves a buffering effect but also compensates for the tolerance length of the material, preventing the material from breaking due to rigid contact during the alignment process.

[0154] In some embodiments, the reference alignment base, reference alignment roller, and reference alignment lifting member in the second film-attaching reference alignment assembly 1500 are respectively: second reference alignment base 1510, second reference alignment roller 1520, and second reference alignment lifting member 1530. The reference alignment groove corresponding to the film-attaching reference alignment assembly is the second reference alignment groove 415.

[0155] Specifically, the second reference alignment base 1510 is connected to the second film alignment drive assembly 2200, the second reference alignment lifting member 1530 is fixed to the second reference alignment base 1510, and the second reference alignment lifting member 1530 is connected to the second reference alignment roller 1520.

[0156] For example, the second string of film-applying alignment drive assembly 2200 includes a second string of film-applying reference drive member 2210, which is a cylinder with a piston rod. A second reference alignment base 1510 is bolted to the piston rod of the second string of film-applying reference drive member 2210, and the second string of film-applying reference drive member 2210 is relatively fixed to the base frame 412. A second reference alignment lifting member 1530 is also a cylinder with a piston rod. The second reference alignment lifting member 1530 is bolted to the bottom surface of the second reference alignment base 1510, and the piston rod of the second reference alignment lifting member 1530 extends upward through the second reference alignment base 1510. A second reference alignment roller 1520 is rotatably disposed on the piston rod of the second reference alignment lifting member 1530.

[0157] When the second reference alignment roller 1520 descends, it can enter below the film-coating platform 410. At this time, the second reference alignment roller 1520 does not obstruct the material transport path.

[0158] When the second reference alignment roller 1520 rises, it is exposed above the film-laying platform 410 through the second reference alignment groove 415. At this time, the second reference alignment roller 1520 blocks the material transport path, and under the drive of the second film-laying reference drive unit 2210, the second reference alignment roller 1520 can slide in the second reference alignment groove 415.

[0159] In some embodiments, the auxiliary alignment base, auxiliary alignment platform, auxiliary alignment roller, auxiliary alignment elastic member, and auxiliary alignment lifting member in the second film-applying auxiliary alignment assembly 1600 are respectively: second auxiliary alignment base 1610, second auxiliary alignment platform 1620, second auxiliary alignment roller 1630, second auxiliary alignment elastic member 1640, and second auxiliary alignment lifting member 1650.

[0160] Specifically, the second auxiliary alignment base 1610 is connected to the second film-applying alignment drive assembly 2200, and the second auxiliary alignment platform 1620 is slidably connected to the second auxiliary alignment base 1610. The second auxiliary alignment lifting member 1650 is fixed to the second auxiliary alignment platform 1620, and the second auxiliary alignment lifting member 1650 is connected to the second auxiliary alignment roller 1630.

[0161] The second auxiliary alignment roller 1630 and the second reference alignment roller 1520 are spaced apart along the second direction. The second auxiliary alignment spring member 1640 is disposed between the second auxiliary alignment base 1610 and the second auxiliary alignment platform 1620, and the second auxiliary alignment spring member 1640 is used to push the second auxiliary alignment platform 1620 to move closer to the second reference alignment roller 1520 along the second direction.

[0162] For example, the second film-applying alignment drive assembly 2200 includes a second film-applying auxiliary drive component 2220, which is a motor screw mechanism with a translation stage. A second auxiliary alignment base 1610 is bolted to the translation stage of the second film-applying auxiliary drive component 2220, and the second film-applying auxiliary drive component 2220 is relatively fixed to the base frame 412. A second auxiliary alignment platform 1620 is slidably connected to the upper side of the second auxiliary alignment base 1610. A second auxiliary alignment elastic component 1640 is a telescopic spring component, which abuts against the side of the second auxiliary alignment platform 1620 opposite to the second reference alignment base 1510.

[0163] The second auxiliary alignment lifting component 1650 is a cylinder with a piston rod. The second auxiliary alignment lifting component 1650 is bolted to the bottom surface of the second auxiliary alignment platform 1620, and the piston rod of the second auxiliary alignment lifting component 1650 extends upward through the second auxiliary alignment platform 1620. The second auxiliary alignment roller 1630 is rotatably mounted on the piston rod of the second auxiliary alignment lifting component 1650.

[0164] When the second auxiliary alignment roller 1630 descends, it can enter below the film-coating platform 410. At this time, the second reference alignment roller 1520 does not obstruct the material transport path.

[0165] When the second auxiliary alignment roller 1630 rises, it is exposed above the film-laying platform 410 through the second auxiliary alignment groove 417. At this time, the second auxiliary alignment roller 1630 blocks the material transport path, and under the drive of the second film-laying auxiliary drive component 2220, the second auxiliary alignment roller 1630 can slide in the second auxiliary alignment groove 417.

[0166] It is understood that when the material needs to be aligned along the second direction, the second set of film-applying reference drive components 2210 drives the second reference alignment base 1510 to move, and the second set of film-applying auxiliary drive components 2220 drives the second auxiliary alignment base 1610 to move, so that the second reference alignment roller 1520 and the second auxiliary alignment roller 1630 respectively abut against the opposite sides of the material in the second direction to achieve the alignment effect. Furthermore, during the process of the second auxiliary alignment roller 1630 abutting against the material, the second auxiliary alignment roller 1630 and the second auxiliary alignment platform 1620 can rebound under the action of the second auxiliary alignment elastic component 1640, which not only achieves a buffering effect but also compensates for the tolerance width of the material, preventing the material from breaking due to rigid contact during the alignment process.

[0167] Figure 14 This is a first structural schematic diagram of the film laminating machine provided in this application. Figure 15 This is a schematic diagram of the second structure of the film laminating machine provided in this application.

[0168] like Figure 3 , Figure 14 and Figure 15As shown, in some embodiments, the gap laminating equipment further includes a transition conveyor line 1000. The transition conveyor line 1000 is disposed on the sheet laminating frame 600 and is located between the string laminating conveyor line 500 and the sheet laminating conveyor line 900. Both ends of the transition conveyor line 1000 are flush with the string laminating conveyor line 500 and the sheet laminating conveyor line 900, respectively. The transition conveyor line 1000 is used to carry and convey material in a second direction. The sheet laminating conveyor line 900 is connected to the string laminating conveyor line 500 through the transition conveyor line 1000, and the transition conveyor line 1000 can rotate or pause independently. Thus, the material that has completed string lamination can be conveyed from the string laminating conveyor line 500 to the transition conveyor line 1000, and then from the transition conveyor line 1000 to the sheet laminating conveyor line 900.

[0169] It is understandable that the transition conveyor line 1000 serves as a separation between the film-coating conveyor line 500 and the sheet-coating conveyor line 900, avoiding interference between the transport of the previous material and the next material. For example, after the previous material has been film-coated, the film-coating conveyor line 500 can transport the previous material to the transition conveyor line 1000 and the sheet-coating conveyor line 900, where the previous material is carried. The film-coating conveyor line 500 can then transport the next material, and the two materials do not interfere with each other.

[0170] In some embodiments, the sheet-applying mechanism 700 includes a translational support 710, a sheet-applying drive assembly 720, a sheet-applying head 730, and a sheet-applying unwinding assembly 740. The sheet-applying drive assembly 720 is connected to the translational support 710 and the sheet-applying frame 600, and is used to drive the translational support 710 to move along a second direction on the sheet-applying frame 600. The sheet-applying head 730 is disposed on the translational support 710 and moves synchronously with it. The sheet-applying head 730 follows the translational support 710 and performs sheet-applying. The sheet-applying unwinding assembly 740 is disposed on the side of the translational support 710 facing the second material changing area 102 and moves synchronously with it. The sheet-applying unwinding assembly 740 is used to position the film reel corresponding to the sheet-applying head 730.

[0171] During sheet lamination, the material is carried on the sheet lamination platform 800. The sheet lamination drive assembly 720 drives the translation bracket 710 to move along the second direction, and drives the sheet lamination head 730 and the sheet lamination unwinding assembly 740 to move synchronously. The sheet lamination head 730 can perform sheet lamination on the material while moving.

[0172] When the film reel of the sheet-applying unwinding assembly 740 needs to be replaced, the sheet-applying drive assembly 720 drives the translation bracket 710 to move along the second direction to the side of the sheet-applying machine frame 600 away from the string-applying machine frame 100. At this time, the operator can replace the film reel of the sheet-applying unwinding assembly 740 in the second material changing area 102 from the side of the sheet-applying machine frame 600 away from the string-applying machine frame 100.

[0173] In this embodiment, the film-applying drive assembly 720 adopts a motor-driven gear and rack structure, and its working principle is the same as that of the first drive assembly 220 (e.g., Figure 4 The same applies as shown in the figure, and will not be repeated here.

[0174] It is worth noting that the number of sheet-applying heads 730 and sheet-applying unwinding assemblies 740 can be configured according to actual conditions. For example, in the example of this application, the sheet-applying heads 730 can be set to 24 groups. The 24 groups of sheet-applying heads 730 can be used to apply sheet-applying film to photovoltaic modules of 78 half-cell type (156 cells) and 72 half-cell type (144 cells). In other embodiments, the number of sheet-applying heads 730 and sheet-applying unwinding assemblies 740 can be adaptively adjusted according to actual conditions. This application does not impose any restrictions on this.

[0175] Figure 16 This is a schematic diagram of the sheet-applying platform provided in this application.

[0176] like Figures 14 to 16 As shown, in some embodiments, the sheet-applying platform 800 includes a sheet-applying stage 810 and a sheet-applying lifting assembly 820. The sheet-applying stage 810 is located below the sheet-applying mechanism 700, and a sheet-applying carrying area is formed above the stage 810. The stage 810 can carry material located in the sheet-applying carrying area. The sheet-applying lifting assembly 820 is connected to the sheet-applying stage 810. The sheet-applying lifting assembly 820 is used to drive the sheet-applying stage 810 to move vertically.

[0177] It is understandable that when the material is carried on the film-applying platform 810, the film-applying lifting assembly 820 can drive the film-applying platform 810 to rise and fall, thereby driving the material to rise and fall, and realizing the function of the material moving up and down relative to the film-applying mechanism 700.

[0178] Thus, the film application mechanism 700 itself does not need to be equipped with an additional lifting structure, which simplifies the structural layout of the film application mechanism 700, reduces the load on the film application mechanism 700, and facilitates the control of the moving position of the film application mechanism 700.

[0179] In some embodiments, the film application lifting assembly 820 includes a film application lifter 821 and a film application lifting drive 822. The film application lifter 821 is a worm gear screw type lifter, having an input shaft and a moving rod. The input shaft of the film application lifter 821 is connected to the film application platform 810 and extends vertically. The film application lifting drive 822 is connected to the moving rod of the film application lifter 821 and is used to drive the moving rod of the film application lifter 821 to rotate.

[0180] For example, the film application lifting drive 822 is a servo motor, which has a body and an output shaft. The body of the film application lifting drive 822 can be fixed to a fixed object such as a base, and the output shaft of the film application lifting drive 822 is connected to the moving rod of the film application lifter 821.

[0181] Thus, the film-applying lifting drive 822 can drive the input shaft of the film-applying lifter 821 to rotate, and use a worm gear screw drive to drive the moving rod of the film-applying lifter 821 to rise and fall, thereby driving the film-applying platform 810 to rise and fall. It can be understood that the worm gear screw structure has the characteristics of anti-reverse rotation and high adjustment precision, which can improve the stability of the lifting action of the film-applying platform 810.

[0182] It is understood that in the example of this application, the film application lifting device 821 adopts a worm gear screw type lifting device. In other embodiments, the film application lifting device 821 may also adopt a gear column type lifting device, as long as it can achieve the effect of driving the film application platform 810 to rise and fall. This application does not impose any restrictions on this.

[0183] like Figure 3 , Figure 14 and Figure 16 As shown, in some embodiments, the sheet-applying conveyor line 900 is located below the sheet-applying mechanism and is arranged along the sheet-applying direction.

[0184] The sheet-applying conveyor line 900 includes multiple sheet-applying synchronous belts 901, each extending along a second direction, and the multiple sheet-applying synchronous belts 901 are spaced apart in a first direction. During material conveying, the multiple sheet-applying synchronous belts 901 simultaneously carry the material and drive it to move along the second direction.

[0185] In this embodiment, a film-applying stage 810 is disposed between multiple film-applying timing belts 901, and multiple second through slots 811 are formed through the film-applying stage 810 at the locations corresponding to the film-applying timing belts 901. When the film-applying stage 810 is raised or lowered, the film-applying timing belts 901 can pass through the second through slots 811 of the film-applying stage 810, so that the film-applying stage 810 can pass vertically between the multiple film-applying timing belts 901.

[0186] Specifically, the film-applying stage 810 has a third height and a fourth height, and the film-applying lifting assembly 820 can drive the film-applying stage 810 to move to the third height or the fourth height. When the film-applying stage 810 is at the third height, the height of the upper surface of the film-applying stage 810 is higher than the height of the upper surface of the film-applying timing belt 901. When the film-applying stage 810 is at the fourth height, the height of the upper surface of the film-applying stage 810 is lower than the height of the upper surface of the film-applying timing belt 901.

[0187] When multiple film-applying synchronous belts 901 move the material above the film-applying platform 810, the film-applying lifting assembly 820 can drive the film-applying platform 810 to rise to a third height, so that the material is supported on the film-applying platform 810 and detached from the multiple film-applying synchronous belts 901.

[0188] When the film-applying platform 810 is carrying materials, the film-applying lifting assembly 820 can drive the film-applying platform 810 to descend to a fourth height so that the materials are carried on multiple film-applying synchronous belts 901 and detached from the film-applying platform 810.

[0189] It is understood that when sheet lamination of materials is required, the sheet lamination platform 810 is initially at the fourth height, and multiple sheet lamination timing belts 901 transport the materials to above the sheet lamination platform 810. Then, the sheet lamination lifting assembly 820 can drive the sheet lamination platform 810 to rise to the third height, lifting the materials from the multiple sheet lamination timing belts 901 for sheet lamination by the sheet lamination mechanism 700. After sheet lamination is completed, the sheet lamination lifting assembly 820 can drive the sheet lamination platform 810 to descend to the fourth height, repositioning the materials onto the multiple sheet lamination timing belts 901 and detaching them from the sheet lamination platform 810. Then, the multiple sheet lamination timing belts 901 continue to transport the materials. Thus, the lifting function of the sheet lamination platform 810 enables material transfer between the sheet lamination platform 810 and the multiple sheet lamination timing belts 901, improving work efficiency.

[0190] like Figure 14 and Figure 15 As shown, in some embodiments, the gap film application device further includes multiple sets of film application alignment mechanisms, all of which are connected to the film application stage 810.

[0191] Each film-applying alignment mechanism includes a film-applying reference alignment component, a film-applying auxiliary alignment component, and a film-applying alignment drive component. The film-applying reference alignment component and the film-applying auxiliary alignment component are located on opposite sides of the film-applying bearing area. The film-applying alignment drive component is connected to the film-applying reference alignment component and the film-applying auxiliary alignment component, and is used to drive the film-applying reference alignment component and the film-applying auxiliary alignment component to move closer to or further apart from each other.

[0192] Thus, when the material is carried on the film-mounting stage 810, the film-mounting alignment drive assembly can drive the film-mounting reference alignment assembly and the film-mounting auxiliary alignment assembly to move closer to each other, so that the film-mounting reference alignment assembly and the film-mounting auxiliary alignment assembly cooperate to hold against the opposite sides of the material, thereby aligning the material.

[0193] In one set of film-applying alignment mechanisms, the film-applying reference alignment component, the film-applying auxiliary alignment component, and the film-applying alignment drive component are defined as the first film-applying reference alignment component 1700, the first film-applying auxiliary alignment component 1800, and the first film-applying alignment drive component, respectively. In another set of film-applying alignment mechanisms, the film-applying reference alignment component, the film-applying auxiliary alignment component, and the film-applying alignment drive component are defined as the second film-applying reference alignment component 1900, the second film-applying auxiliary alignment component 2000, and the second film-applying alignment drive component, respectively.

[0194] The first film application reference alignment component 1700 and the first film application auxiliary alignment component 1800 are spaced apart along a first direction. The second film application reference alignment component 1900 and the second film application auxiliary alignment component 2000 are spaced apart along a second direction.

[0195] Thus, the first film-applying reference alignment component 1700 and the first film-applying auxiliary alignment component 1800 can align the material in the first direction, and the second film-applying reference alignment component 1900 and the second film-applying auxiliary alignment component 2000 can align the material in the second direction, ensuring that the material does not deviate from its position.

[0196] In this embodiment, the implementation principle of the first film-applying reference alignment component 1700 is the same as that of the first series of film-applying reference alignment components 1300 (e.g., Figure 12 The implementation principle is the same as that of the first film-applying auxiliary alignment component 1800 (as shown), and the implementation principle of the first film-applying auxiliary alignment component 1400 (as shown) is the same. Figure 12 The implementation principle of the second film-applying reference alignment component 1900 is the same as that of the second film-applying reference alignment component 1500 (as shown). Figure 12 The implementation principle of the second film-applying auxiliary alignment component 2000 is the same as that of the second film-applying auxiliary alignment component 1600 (as shown). Figure 12 The implementation principle is the same as that shown in the figure, and will not be repeated here.

[0197] like Figure 3 , Figure 14 and Figure 16As shown, in some embodiments, the gap laminating equipment further includes a folding conveyor line 1100, which is disposed on the side of the sheet laminating frame 600 away from the string laminating frame 100. The folding conveyor line 1100 has a flat state and a folded state that can be switched by rotation.

[0198] When the folding conveyor line 1100 is in a flat position, it connects with the sheet-applying conveyor line 900. The sheet-applying conveyor line 900 can transport the finished sheet-applying material to the folding conveyor line 1100 so that the material can flow into the next production line.

[0199] When the folding conveyor line 1100 is in a folded state, it does not connect with the film application conveyor line 900. The folding conveyor line 1100 itself flips and folds to leave a certain space on the side of the film application machine frame 600, which facilitates the operation of changing materials by the staff.

[0200] In some embodiments, the folding conveyor line 1100 includes a folding timing belt 1110 and a rotary drive assembly 1120. The folding timing belt 1110 is located on the side of the sheet laminating frame 600 away from the string laminating frame 100 and is rotatably connected to the sheet laminating frame 600. The rotary drive assembly 1120 is disposed on the sheet laminating frame 600 and connected to the folding timing belt 1110. The rotary drive assembly 1120 drives the folding timing belt 1110 to rotate to a flat state or a folded state. When the folding timing belt 1110 is in the flat state, it is used to dock with the sheet laminating conveyor line 900.

[0201] For example, the rotary drive assembly 1120 can be a telescopic pneumatic rod, which has a cylinder and a piston rod. The cylinder of the rotary drive assembly 1120 is rotatably connected to the sheet laminating frame 600, and the piston rod of the rotary drive assembly 1120 is rotatably connected to the folding timing belt 1110. The rotary drive assembly 1120 drives the folding timing belt 1110 to rotate vertically by extending and retracting the piston rod within the cylinder.

[0202] When the folding synchronous belt 1110 rotates to the horizontal position, it is parallel to the horizontal direction and aligned with the film-applying conveyor line 900. At this time, the folding synchronous belt 1110 can receive materials from the film-applying conveyor line 900. When the folding synchronous belt 1110 rotates to the folded position, it is parallel to the vertical direction. At this time, it cannot receive materials from the film-applying conveyor line 900, and it folds downwards to provide sufficient space for workers to stand.

[0203] like Figure 14 and Figure 15As shown, in some embodiments, the gap laminating equipment further includes a detection mechanism 1200, which is located on the side of the sheet laminating frame 600 away from the string laminating frame 100. The detection mechanism 1200 is used to detect the laminating quality of the materials that have completed string laminating and sheet laminating, and the detection items can include defects such as film misalignment, missing film strips, and film strip stretching.

[0204] For example, the inspection mechanism 1200 is located between the film application conveyor line 900 and the folding conveyor line 1100. The inspection mechanism 1200 includes a light source and a camera 1210. The light source is disposed on the film application machine frame 600, and the height of the light source is lower than the upper surface of the film application conveyor line 900. The camera 1210 is disposed on the film application machine frame 600, and the height of the light source is higher than the upper surface of the film application conveyor line 900. When the material is conveyed from the film application conveyor line 900 to the folding conveyor line 1100, the light source can illuminate from bottom to top, and the camera 1210 can take pictures from top to bottom. The film application quality is inspected by analyzing the images captured by the camera 1210.

[0205] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
