Description

Technical Field

[0001] This application relates to the field of photovoltaic equipment manufacturing technology, and more specifically, to a film-laying device. Background Technology

[0002] After being strung together, photovoltaic cells are arranged in a rectangular pattern on a backsheet glass. Gaps exist between the rectangularly arranged cells, which are typically covered by a film strip. In related technologies, the film-laying device simultaneously unwinds and lays the film strip. Because the unwinding speed of the film strip is relatively slow, and the film-laying speed of the device is limited by the unwinding speed of the feeding mechanism, the film-laying device requires a longer laying time when laying longer film strips. Utility Model Content

[0003] In view of this, this application provides a film laying device that can increase the speed of film laying.

[0004] One embodiment of this application provides a film-laying apparatus for laying film onto a working surface of material. The film-laying apparatus includes a frame, a feeding mechanism, a buffer mechanism, and a film-laying mechanism. The frame is provided with a film-laying track. The film-laying track is arranged parallel to the working surface. The feeding mechanism is located on the frame and is used to output film strips. The buffer mechanism is located on the frame and is used to receive and buffer the film strips from the feeding mechanism. The film-laying mechanism is located on the frame and is movable along the film-laying track. The film-laying mechanism is used to receive film strips from the buffer mechanism. The film-laying mechanism moves along the film-laying track to lay film onto the working surface, and the single-pass film-laying length of the film-laying mechanism along the film-laying track is less than the maximum length of film strip buffered by the buffer mechanism.

[0005] In some embodiments of this application, the buffer mechanism includes a buffer base, a buffer wheel, a first guide wheel, and a second guide wheel. The buffer base is mounted on a frame. The buffer base has a buffer track. The buffer wheel is mounted on the buffer base and is movable along the buffer track; the buffer wheel is used to buffer the film strip. The first guide wheel is mounted on the buffer base. The first guide wheel is used to receive the film strip from the feeding mechanism and guide it to the buffer wheel. The second guide wheel is mounted on the buffer base. The second guide wheel is used to receive the film strip from the buffer wheel and guide it to the film-laying mechanism. When the buffer wheel moves away from the first guide wheel, it also moves away from the second guide wheel to buffer the film strip.

[0006] In some embodiments of this application, multiple buffer wheels are provided. The buffer mechanism also includes at least one fixed wheel. The fixed wheels are all disposed on the buffer base. The fixed wheels are used for the membrane strip wound from one buffer wheel to be wound around one fixed wheel and then rewound to another buffer wheel, so that multiple segments of the membrane strip are formed between each buffer wheel and each fixed wheel.

[0007] In some embodiments of this application, the caching mechanism further includes a caching support. Multiple caching wheels are disposed on the caching support. The caching support is movably mounted on a caching track.

[0008] In some embodiments of this application, the film-laying mechanism includes a first film-laying assembly and a second film-laying assembly. The first film-laying assembly and the second film-laying assembly are respectively movable along a film-laying track.

[0009] In some embodiments of this application, the film-laying mechanism further includes a first film-laying moving member and a second film-laying moving member. The first film-laying assembly is disposed on the first film-laying moving member. The first film-laying moving member is movably configured along a film-laying track and is used to drive the first film-laying assembly to move in a direction perpendicular to the working surface. The second film-laying assembly is disposed on the second film-laying moving member. The second film-laying moving member is movably configured along a film-laying track and is used to drive the second film-laying assembly to move in a direction perpendicular to the working surface.

[0010] In some embodiments of this application, the film-laying mechanism further includes a shearing member. The shearing member is connected to the first film-laying assembly to move with it. The shearing member is used to cut the film strip on the side of the first film-laying assembly closer to the second film-laying assembly.

[0011] In some embodiments of this application, a first film-laying assembly includes a first positioning member, a first clamping member, and a first clamping drive member. The first positioning member is movably disposed along a film-laying track. The first positioning member is used to receive the film strip from the buffer mechanism. The first clamping member is movably disposed on the first positioning member. The first clamping drive member is connected to the first clamping member. The first clamping drive member is used to drive the first clamping member to move relative to the first positioning member, so that the first clamping member and the first positioning member clamp the film strip. A second film-laying assembly includes a second positioning member, a second clamping member, and a second clamping drive member. The second positioning member is movably disposed along a film-laying track. The second positioning member is used to receive the film strip from the first positioning member. The second clamping member is movably disposed on the second positioning member. The second clamping drive member is connected to the second clamping member. The second clamping drive member is used to drive the second clamping member to move relative to the second positioning member, so that the second clamping member and the second positioning member clamp the film strip.

[0012] In some embodiments of this application, multiple feeding mechanisms, buffer mechanisms, first film-laying components, and second film-laying components are provided. Furthermore, one feeding mechanism, one buffer mechanism, one first film-laying component, and one second film-laying component cooperate to lay film on one film strip.

[0013] In some embodiments of this application, a first film-laying assembly and a second film-laying assembly form a group. Multiple groups of first and second film-laying assemblies are arranged alternately. The arrangement direction of the multiple groups of first and second film-laying assemblies is parallel to the working surface and perpendicular to the arrangement direction of any one group of first and second film-laying assemblies. The frame also includes a feeding track, a feeding moving component, a buffer moving track, and a buffer moving component. The extending direction of the feeding track is parallel to the arrangement direction of the multiple groups of first and second film-laying assemblies. Multiple feeding mechanisms are movably disposed on the feeding track. Multiple feeding moving components are provided. Each feeding moving component is connected to a feeding mechanism and used to drive the connected feeding mechanism to move along the feeding track. The extending direction of the buffer moving track is parallel to the arrangement direction of the multiple groups of first and second film-laying assemblies. Multiple buffer mechanisms are movably disposed on the buffer moving track. Multiple buffer moving components are provided. Each buffer moving component is connected to a buffer mechanism and used to drive the connected buffer mechanism to move along the buffer moving track.

[0014] In this application, when the feeding mechanism outputs the film strip used for film laying to the film laying mechanism, the film strip passes through a buffer mechanism after being output from the feeding mechanism and before reaching the film laying mechanism. This buffer mechanism can temporarily store a portion of the film strip. As the film laying mechanism moves along the film laying track towards the film laying position on the material's working surface, it moves relative to the buffer mechanism. This allows the film laying mechanism to extract the film strip from the buffer mechanism. The film strip used by the film laying mechanism comes directly from the portion buffered by the buffer mechanism, rather than being directly supplied by the feeding mechanism. This allows the film laying speed of the film laying mechanism to be unaffected by the speed of the film strip output by the feeding mechanism, thereby increasing the film laying speed. Furthermore, the film strip buffered by the buffer mechanism is sufficient for the film laying mechanism to perform one film laying operation, enabling the film laying mechanism to smoothly and continuously perform one film laying operation without having to stop midway due to a lack of film strip supply. Furthermore, when the film-laying mechanism fixes the film strip to the working surface of the material and resets to prepare for the next film-laying operation, the feeding mechanism can continuously output film strip to the buffer mechanism, so that the buffer mechanism can buffer the film strip required for the next film-laying operation of the film-laying mechanism. This allows the film-laying mechanism to continuously perform film-laying operations and improves the overall film strip laying speed when performing multiple film-laying operations.

[0018] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0020] Furthermore, the terms “first,” “second,” “third,” etc., are used for descriptive purposes only and should not be interpreted as indicating or implying relative importance.

[0021] This application provides a film-laying apparatus for laying film onto a working surface of material. The film-laying apparatus includes a frame, a feeding mechanism, a buffer mechanism, and a film-laying mechanism. The frame is provided with a film-laying track. The film-laying track is arranged parallel to the working surface. The feeding mechanism is located on the frame and is used to output film strips. The buffer mechanism is located on the frame and is used to receive and buffer the film strips from the feeding mechanism. The film-laying mechanism is located on the frame and is movable along the film-laying track. The film-laying mechanism is used to receive film strips from the buffer mechanism. The film-laying mechanism moves along the film-laying track to lay film onto the working surface, and the single film-laying length of the film-laying mechanism along the film-laying track is less than the maximum length of film strip buffered by the buffer mechanism.

[0022] When the feeding mechanism supplies the film strip to the film-laying mechanism, the film strip passes through a buffer mechanism after being supplied and before reaching the film-laying mechanism. This buffer mechanism temporarily stores a portion of the film strip. As the film-laying mechanism moves along the film-laying track towards the film-laying position on the working surface, it moves relative to the buffer mechanism. This allows the film-laying mechanism to extract the film strip from the buffer mechanism. The film strip used by the film-laying mechanism comes directly from the portion buffered by the buffer mechanism, rather than being directly supplied by the feeding mechanism. This allows the film-laying speed of the film-laying mechanism to be unaffected by the speed of the film strip supplied by the feeding mechanism, thereby increasing the film-laying speed. The film strip buffered by the buffer mechanism is sufficient for the film-laying mechanism to perform one film-laying operation, enabling the film-laying mechanism to smoothly and continuously perform one film-laying operation without stopping midway due to a lack of film strip supply. Furthermore, when the film-laying mechanism fixes the film strip to the working surface of the material and resets to prepare for the next film-laying operation, the feeding mechanism can continuously output film strip to the buffer mechanism, so that the buffer mechanism can buffer the film strip required for the next film-laying operation of the film-laying mechanism. This allows the film-laying mechanism to continuously perform film-laying operations and improves the overall film strip laying speed when performing multiple film-laying operations.

[0023] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0024] See Figure 1 One embodiment of this application provides a film-laying apparatus 100 for laying a film strip 200 onto a working surface 301 of a material 300. The material 300 consists of rectangularly arranged photovoltaic cells, and the working surface 301 is the gap between adjacent photovoltaic cells.

[0025] See Figure 1 and Figure 2 In some embodiments, the film-laying apparatus 100 includes a frame 10, a feeding mechanism 20, a buffer mechanism 30, and a film-laying mechanism 40. The feeding mechanism 20, the buffer mechanism 30, and the film-laying mechanism 40 are all located on the frame 10.

[0026] The frame 10 is equipped with a film-laying track 11. The film-laying track 11 is arranged parallel to the working surface 301. The feeding mechanism 20 is used to output the film strip 200. The buffer mechanism 30 is used to receive the film strip 200 from the feeding mechanism 20 and buffer the film strip 200. The film-laying mechanism 40 is movable along the film-laying track 11. The film-laying mechanism 40 is used to receive the film strip 200 from the buffer mechanism 30. The film-laying mechanism 40 moves along the film-laying track 11 to lay film on the working surface 301, and the single film-laying length of the film-laying mechanism 40 moving along the film-laying track 11 is less than the maximum length of the film strip 200 buffered by the buffer mechanism 30.

[0027] When the feeding mechanism 20 outputs the film strip 200 for film laying to the film laying mechanism 40, the film strip 200 passes through the buffer mechanism 30 after being output from the feeding mechanism 20 and before reaching the film laying mechanism 40, and the buffer mechanism 30 can temporarily store a portion of the film strip 200. When the film laying mechanism 40 moves along the film laying track 11 to the film laying position on the working surface 301 of the material 300, the film laying mechanism 40 moves relative to the buffer mechanism 30, so that the film laying mechanism 40 can extract the film strip 200 from the buffer mechanism 30. The film strip 200 used by the film laying mechanism 40 comes directly from the portion buffered by the buffer mechanism 30 and is not directly output by the feeding mechanism 20. This is beneficial because the film laying speed of the film laying mechanism 40 is not limited by the speed of the film strip 200 output by the feeding mechanism 20, thereby increasing the laying speed of the film strip 200 and facilitating the laying efficiency of longer film strips 200. The buffer mechanism 30 stores film strip 200, which is sufficient for the film-laying mechanism 40 to perform one film-laying operation. This allows the film-laying mechanism 40 to smoothly and continuously perform one film-laying operation without having to stop midway due to a lack of film strip 200 supply. Furthermore, when the film-laying mechanism 40 fixes the film strip 200 to the working surface 301 of the material 300 and resets to prepare for the next film-laying operation, the feeding mechanism 20 can continuously output film strip 200 to the buffer mechanism 30. This allows the buffer mechanism 30 to store the required film strip 200 for the next film-laying operation, enabling the film-laying mechanism 40 to continuously perform film-laying operations and increasing the overall film strip 200 laying speed when performing multiple film-laying operations.

[0028] In some embodiments, the first direction X is defined as the extension direction of the film-laying track 11, and the second direction Z and the third direction Y are defined as directions that are both perpendicular to the first direction X, and the first direction X, the second direction Z, and the third direction Y are mutually perpendicular. When the film-laying device 100 is in use, the film-laying track 11 is arranged horizontally; for example, the first direction X and the third direction Y are both perpendicular to the direction of gravity, and the second direction Z is parallel to the direction of gravity.

[0029] In some embodiments, the feeding mechanism 20 includes a feeding base 21 and an unwinding reel 22. The feeding base 21 is disposed on the frame 10. The unwinding reel 22 is rotatably disposed on the feeding base 21. The unwinding reel 22 is used to hold the film strip 200 prepared for laying, wherein the film strip 200 is wound on the unwinding reel 22, and the rotation of the unwinding reel 22 unwinds the wound film strip 200 to output the film strip 200.

[0030] See Figure 1 and Figure 3 In some embodiments, the buffer mechanism 30 includes a buffer base 31, a buffer wheel 32, a first guide wheel 33, and a second guide wheel 34. The buffer base 31 is mounted on the frame 10. The buffer base 31 has a buffer track 311. The buffer wheel 32 is mounted on the buffer base 31 and is movable along the buffer track 311; the buffer wheel 32 is used to buffer the film strip 200. The first guide wheel 33 is mounted on the buffer base 31. The first guide wheel 33 is used to receive the film strip 200 from the feeding mechanism 20 and guide it to the buffer wheel 32. The second guide wheel 34 is mounted on the buffer base 31. The second guide wheel 34 is used to receive the film strip 200 from the buffer wheel 32 and guide it to the film-laying mechanism 40. When the buffer wheel 32 moves away from the first guide wheel 33, the buffer wheel 32 also moves away from the second guide wheel 34 to buffer the film strip 200.

[0031] The buffer roller 32 is movable, so when the buffer roller 32 moves away from the first guide roller 33 and the second guide roller 34, the membrane belt 200 segments between the buffer roller 32 and the first guide roller 33 and between the buffer roller 32 and the second guide roller 34 lengthen, thereby temporarily storing the membrane belt 200; while when the buffer roller 32 moves closer to the first guide roller 33 and the second guide roller 34, the membrane belt 200 segments between the buffer roller 32 and the first guide roller 33 and between the buffer roller 32 and the second guide roller 34 shorten, thereby releasing the membrane belt 200. Specifically, before the film-laying mechanism 40 lays the film, the buffer roller 32 can move away from the first guide roller 33 and the second guide roller 34 to temporarily store the membrane belt 200; during the film-laying mechanism 40 lays the film, the buffer roller 32 can move closer to the first guide roller 33 and the second guide roller 34 to provide the temporarily stored membrane belt 200 to the film-laying mechanism 40. Furthermore, by utilizing the movable buffer wheel 32, the membrane belt 200 output in advance by the feeding mechanism 20 is wound in an orderly manner, avoiding the membrane belt 200 from being messily tangled and affecting the laying.

[0032] See Figure 2 and Figure 3 It is understood that in some embodiments, the extension direction of the buffer track 311 intersects with the film-laying track 11. For example, the buffer track 311 can extend along the second direction Z. The direction of the buffer mechanism 30 for buffering the film strip 200 is different from the direction of the film-laying mechanism 40 for laying the film strip 200, making reasonable use of space and reducing the impact on the loading and unloading of materials 300. For example, when the film-laying device 100 is in use, the extension direction of the buffer track 311 is parallel to the direction of gravity, and the buffer wheel 32 is located below the first guide wheel 33 and the second guide wheel 34. Under its own gravity, the buffer wheel 32 can move away from the first guide wheel 33 and the second guide wheel 34, which facilitates the automatic buffering of the film strip 200 by the buffer mechanism 30.

[0033] Understandably, in some embodiments, multiple first guide wheels 33 are provided to more stably guide the film belt 200 of the feeding mechanism 20 to the buffer wheel 32; multiple second guide wheels 34 are provided to more stably guide the film belt 200 of the buffer wheel 32 to the film laying mechanism 40.

[0034] In some embodiments, multiple buffer wheels 32 are provided. The buffer mechanism 30 also includes at least one fixed wheel 35. The fixed wheels 35 are all disposed on the buffer base 31. The fixed wheels 35 are used for the membrane strip 200 wound from one buffer wheel 32 to be wound around one fixed wheel 35 and then rewound to another buffer wheel 32, so that multiple segments of the membrane strip 200 are formed between each buffer wheel 32 and each fixed wheel 35. The second guide wheel 34 can directly receive the membrane strip 200 led out from the buffer wheel 32, or indirectly receive the membrane strip 200 led out from the buffer wheel 32 through the fixed wheel 35.

[0035] With the cooperation of the fixed roller 35, the membrane belt 200 can be wound around multiple buffer rollers 32, thereby buffering more membrane belts 200 with the same buffer track 311 length. Furthermore, when multiple membrane belts 200 are wound around multiple buffer rollers 32, the buffer mechanism 30 can provide greater tension to the membrane belts 200, ensuring stable transport of the membrane belts 200 between the feeding mechanism 20, the buffer mechanism 30, and the film-laying mechanism 40.

[0036] It is understood that in some embodiments, L1 is defined as the maximum length of the film strip 200 buffered by the buffer mechanism 30, and L2 is defined as the single film laying length of the film laying mechanism 40; wherein, L1 = the length of the film strip 200 segment between the buffer wheel 32 and the first guide wheel 33 + the length of the film strip 200 segment between the buffer wheel 32 and the second guide wheel 34 + the length of the film strip 200 segment between the buffer wheel 32 and the fixed wheel 35, and L1 > L2; under the above conditions, it is beneficial to ensure that the film laying device 100 meets the requirement that the film laying speed of the film laying mechanism 40 is not limited by the speed of the film strip 200 output by the feeding mechanism 20 during each film laying operation.

[0037] Understandably, in some embodiments, L3 is defined as the maximum distance the buffer wheel 32 moves along the buffer track 311, and N is the number of segments of the membrane belt 200 buffered by the buffer mechanism 30; wherein, N = the number of membrane belt 200 segments between the buffer wheel 32 and the first guide wheel 33 + the number of membrane belt 200 segments between the buffer wheel 32 and the second guide wheel 34 + the number of membrane belt 200 segments between the buffer wheel 32 and the fixed wheel 35, N is a positive integer, and L1:L3 is approximately N. For example, if the membrane belt 200 is wound around the first guide wheel 33 to a buffer wheel 32, then to another buffer wheel 32, then to a fixed wheel 35, then to yet another buffer wheel 32, and then to the second guide wheel 34, then N=4, and L1:L3 is approximately 4.

[0038] In some embodiments, the cache mechanism 30 further includes a cache support 36. A plurality of cache wheels 32 are disposed on the cache support 36. The cache support 36 is movably mounted on a cache track 311.

[0039] By setting the buffer bracket 36, multiple buffer wheels 32 can move synchronously, so as to avoid large movement deviations between different buffer wheels 32 when the buffer mechanism 30 buffers the membrane belt 200. When the buffer mechanism 30 buffers the membrane belt 200 and the membrane laying mechanism 40 lays the membrane belt 200, the movement frequency and amplitude of the membrane belt 200 are reduced, improving the conveying stability of the membrane belt 200 and facilitating the buffering and laying of the membrane belt 200.

[0040] See Figure 1 and Figure 4 In some embodiments, the film-laying mechanism 40 includes a first film-laying assembly 41 and a second film-laying assembly 42. The first film-laying assembly 41 and the second film-laying assembly 42 are respectively movably disposed along the film-laying track 11. The first film-laying assembly 41 is closer to the buffer mechanism 30 than the second film-laying assembly 42 along the extending direction of the film-laying track 11. The first film-laying assembly 41 is used to receive the film strip 200 from the buffer mechanism 30 and guide it to the second film-laying assembly 42. The second film-laying assembly 42 is used to receive the film strip 200 from the first film-laying assembly 41. When the second film-laying assembly 42 moves away from the first film-laying assembly 41, the second film-laying assembly 42 can drive the film strip 200 located between the second film-laying assembly 42 and the first film-laying assembly 41 to the film-laying position on the working surface 301. It is understood that in some embodiments, the first film-laying assembly 41 and the second film-laying assembly 42 are distributed along a first direction X.

[0041] The first film-laying assembly 41 is movable, allowing it to be positioned close to the buffer mechanism 30 to receive the film tape 200 after the film-laying device 100 replaces the film tape 200. The second film-laying assembly 42 is also movable, allowing the first and second film-laying assemblies 41 and 42 to be positioned on opposite sides of the film-laying area on the working surface 301, respectively, so that the film tape 200 between them can be laid onto the working surface 301.

[0042] See Figure 1 It is understood that in some embodiments, when the film laying mechanism 40 lays the film, the first film laying component 41 and the second film laying component 42 are located on both sides of the film laying position on the working surface 301, and L2 is the distance between the first film laying component 41 and the second film laying component 42.

[0043] See Figure 1 , Figure 4 and Figure 5 In some embodiments, the first film-laying assembly 41 includes a first positioning member 411, a first clamping member 412, and a first clamping drive member 413. The first positioning member 411 is movably disposed along the film-laying track 11. The first positioning member 411 is used to receive the film strip 200 from the buffer mechanism 30. The first clamping member 412 is movably disposed on the first positioning member 411. The first clamping drive member 413 is connected to the first clamping member 412. The first clamping drive member 413 is used to drive the first clamping member 412 to move relative to the first positioning member 411, so that the first clamping member 412 and the first positioning member 411 clamp the film strip 200. Exemplarily, the first clamping drive member 413 is a cylinder or a motor.

[0044] Driven by the first clamping drive 413, the first positioning member 411 and the first clamping member 412 cooperate to clamp and fix the film strip 200 or release the film strip 200. When the film strip 200 of the receiving buffer mechanism 30 or the second film laying assembly 42 pulls the film strip 200, the first film laying assembly 41 can release the film strip 200 to allow the film strip 200 to move; when the film laying mechanism 40 lays the film, the first film laying assembly 41 can clamp the film strip 200 to facilitate the movement of the film strip 200.

[0045] The second film-laying assembly 42 includes a second positioning member 421, a second clamping member 422, and a second clamping drive member 423. The second positioning member 421 is movably disposed along the film-laying track 11. The second positioning member 421 is used to receive the film strip 200 from the first positioning member 411. The second clamping member 422 is movably disposed on the second positioning member 421. The second clamping drive member 423 is connected to the second clamping member 422. The second clamping drive member 423 is used to drive the second clamping member 422 to move relative to the second positioning member 421, so that the second clamping member 422 and the second positioning member 421 clamp the film strip 200. For example, the second clamping drive member 423 is a cylinder or a motor.

[0046] Driven by the second clamping drive 423, the second positioning member 421 and the second clamping member 422 cooperate to clamp and fix the film strip 200 or release the film strip 200. When the second film laying assembly 42 performs the next film laying operation, the second film laying assembly 42 can release the previously laid film strip 200 to allow the second film laying assembly 42 to reset; when the second film laying assembly 42 receives the film strip 200 from the first film laying assembly 41, pulls the film strip 200 to move, or when the film laying mechanism 40 lays the film, the second film laying assembly 42 can clamp the film strip 200 to facilitate the movement of the film strip 200.

[0047] In some embodiments, the film-laying mechanism 40 further includes a first film-laying moving member 43 and a second film-laying moving member 44. A first film-laying assembly 41 is disposed on the first film-laying moving member 43. The first film-laying moving member 43 is movably disposed along the film-laying track 11 and is used to drive the first film-laying assembly 41 to move in a direction perpendicular to the working surface 301. A second film-laying assembly 42 is disposed on the second film-laying moving member 44. The second film-laying moving member 44 is movably disposed along the film-laying track 11 and is used to drive the second film-laying assembly 42 to move in a direction perpendicular to the working surface 301. The first film-laying moving member 43 drives the first positioning member 411 to move, and the second film-laying moving member 44 drives the second positioning member 421 to move. Exemplarily, the direction perpendicular to the working surface 301 is the second direction Z.

[0048] By setting the first film-laying moving part 43 and the second film-laying moving part 44, it is convenient for the first film-laying assembly 41 and the second film-laying assembly 42 to avoid materials 300 or other equipment when moving along the film-laying track 11. It also enables the first film-laying assembly 41 and the second film-laying assembly 42 to drive the film belt 200 down to the working surface 301, so as to realize the laying of the film belt 200.

[0049] Understandably, in some embodiments, the first film-laying moving member 43 moves itself along the first direction X to drive the first film-laying assembly 41 to move along the first direction X, and the first film-laying moving member 43 can also drive the first film-laying assembly 41 to move along the second direction Z; the second film-laying moving member 44 moves itself along the first direction X to drive the second film-laying assembly 42 to move along the first direction X, and the second film-laying moving member 44 can also drive the second film-laying assembly 42 to move along the second direction Z.

[0050] For example, the first film-laying moving member 43 has multiple cylinders or motors so that it can move along the film-laying track 11 on its own and drive the first film-laying assembly 41 to move in a direction perpendicular to the working surface 301; the second film-laying moving member 44 has multiple cylinders or motors so that it can move along the film-laying track 11 on its own and drive the second film-laying assembly 42 to move in a direction perpendicular to the working surface 301.

[0051] See Figure 5 and Figure 6 It is understood that in some embodiments, the first clamping member 412 is rotatably disposed on the first positioning member 411. Through rotational engagement, the first clamping member 412 and the first positioning member 411 are stably connected, facilitating stable clamping engagement or disengagement between the first clamping member 412 and the first positioning member 411. The second clamping member 422 is rotatably disposed on the second positioning member 421. Through rotational engagement, the second clamping member 422 and the second positioning member 421 are stably connected, facilitating stable clamping engagement or disengagement between the second clamping member 422 and the second positioning member 421.

[0052] Understandably, in some embodiments, the first clamping member 412 is provided with a first strip-shaped hole 4121, and the output end of the first clamping drive member 413 passes through the first strip-shaped hole 4121 and can move relative to it through the first strip-shaped hole 4121. By providing the first strip-shaped hole 4121, it is convenient for the output end of the first clamping drive member 413 to move linearly and drive the first clamping member 412 to rotate, which helps to reduce the difficulty of the first clamping drive member 413 driving the first clamping member 412, thereby simplifying the structure of the first film-laying assembly 41. The second clamping member 422 is provided with a second strip-shaped hole 4221, and the output end of the second clamping drive member 423 passes through the second strip-shaped hole 4221 and can move relative to it through the second strip-shaped hole 4221. By providing the second strip-shaped hole 4221, it is convenient for the output end of the second clamping drive member 423 to move linearly and drive the second clamping member 422 to rotate, which helps to reduce the difficulty of the second clamping drive member 423 driving the second clamping member 422, thereby simplifying the structure of the second film-laying assembly 42.

[0053] In other embodiments, the first clamping drive member 413 and the first clamping member 412 are inclined surfaces engaged, and the first clamping drive member 413 can push the first clamping member 412 to clamp and engage with the first positioning member 411; the second clamping drive member 423 and the second clamping member 422 are inclined surfaces engaged, and the second clamping drive member 423 can push the second clamping member 422 to clamp and engage with the second positioning member 421.

[0054] In some embodiments, the first clamping member 412 is driven to move closer to or away from the first positioning member 411 by a first clamping drive member 413, and the second clamping member 422 is driven to move closer to or away from the second positioning member 421 by a second clamping drive member 423, for accurate control. In other embodiments, the film-laying mechanism 40 further includes an elastic member, and the movement of the first clamping member 412 closer to or away from the first positioning member 411 can be driven by the elastic member, as can the movement of the second clamping member 422 closer to or away from the second positioning member 421.

[0055] In some embodiments, the first positioning member 411 is provided with a first guide opening 4111, and the second positioning member 421 is provided with a second guide opening 4211. Both the first guide opening 4111 and the second guide opening 4211 are used for the film strip 200 to pass through, so as to constrain the position of the film strip 200. It is understood that in some embodiments, the first clamping member 412 can press the film strip 200 into the first guide opening 4111, and the second clamping member 422 can press the film strip 200 into the second guide opening 4211.

[0056] See Figures 4 to 6 In some embodiments, the film-laying mechanism 40 further includes a shearing member 45. The shearing member 45 is connected to the first film-laying assembly 41 and moves with the first film-laying assembly 41. The shearing member 45 is used to cut the film strip 200 on the side of the first film-laying assembly 41 near the second film-laying assembly 42. After each film-laying operation, the shearing member 45 cuts the film strip 200, and the second film-laying assembly 42 returns to the side of the first film-laying assembly 41 to re-receive the film strip 200 for the next film-laying operation, facilitating the automated repetitive execution of the film-laying operation by the film-laying mechanism 40.

[0057] Understandably, in some embodiments, the shearing member 45 includes a shearing head 451 and a shearing moving member 452. The shearing head 451 is used to cut the film strip 200, and the shearing moving member 452 is connected to the shearing head 451 to drive the shearing head 451 to move; the direction of movement of the shearing head 451 intersects the extension direction of the film laying track 11 so that the shearing head 451 avoids the second film laying assembly 42 when the second film laying assembly 42 moves closer to the first film laying assembly 41. Exemplarily, the shearing head 451 is a pneumatically controlled scissor or an electrically controlled scissor, and the shearing moving member 452 is a cylinder or a motor. Understandably, in some embodiments, the shearing moving member 452 drives the shearing head 451 to move along a third direction Y.

[0058] See Figure 1 , Figure 2 and Figure 4 In some embodiments, multiple feeding mechanisms 20, buffer mechanisms 30, first film-laying components 41, and second film-laying components 42 are provided. Furthermore, one feeding mechanism 20, one buffer mechanism 30, one first film-laying component 41, and one second film-laying component 42 cooperate to lay film on a film strip 200.

[0059] The installation of multiple feeding mechanisms 20, buffer mechanisms 30, first film-laying assembly 41, and second film-laying assembly 42 enables the film-laying device 100 to lay multiple film strips 200 simultaneously, thereby improving film-laying efficiency.

[0060] In some embodiments, the film-laying mechanism 40 further includes a first film-laying base 46 and a second film-laying base 47. A plurality of first film-laying assemblies 41 are spaced apart on the first film-laying base 46, and the first film-laying base 46 is disposed on a first film-laying moving member 43, so that the first film-laying moving member 43 can simultaneously drive the plurality of first film-laying assemblies 41 to move. A plurality of second film-laying assemblies 42 are spaced apart on the second film-laying base 47, and the second film-laying base 47 is disposed on a second film-laying moving member 44, so that the second film-laying moving member 44 can simultaneously drive the plurality of second film-laying assemblies 42 to move.

[0061] In some embodiments, a first film-laying assembly 41 and a second film-laying assembly 42 constitute a group. Multiple groups of first film-laying assemblies 41 and second film-laying assemblies 42 are arranged at intervals. The arrangement direction of the multiple groups of first film-laying assemblies 41 and second film-laying assemblies 42 is parallel to the working surface 301 and perpendicular to the arrangement direction of any one group of first film-laying assemblies 41 and second film-laying assemblies 42.

[0062] The rack 10 also includes a feed rail 12, a feed moving part 13, a buffer moving rail 14, and a buffer moving part 15. For example, the feed rail 12 and the buffer moving rail 14 may extend along a third direction Y.

[0063] The extending direction of the feeding track 12 is parallel to the arrangement direction of the multiple sets of first film-laying assemblies 41 and second film-laying assemblies 42. Multiple feeding mechanisms 20 are movably disposed on the feeding track 12. Multiple feeding moving parts 13 are provided. Each feeding moving part 13 is connected to a feeding mechanism 20 and is used to drive the connected feeding mechanism 20 to move along the feeding track 12. The feeding base 21 of each feeding mechanism 20 is movably disposed on the feeding track 12. For example, the feeding moving part 13 is a cylinder or a motor. Under the drive of the feeding moving part 13, the multiple feeding mechanisms 20 can adjust their positions on the feeding track 12 so that each feeding mechanism 20 corresponds to the position of each set of first film-laying assemblies 41 and second film-laying assemblies 42.

[0064] The extension direction of the buffer moving track 14 is parallel to the arrangement direction of the multiple sets of first film-laying assemblies 41 and second film-laying assemblies 42. Multiple buffer mechanisms 30 are movably disposed on the buffer moving track 14. Multiple buffer moving members 15 are provided. Each buffer moving member 15 is connected to a buffer mechanism 30 and is used to drive the connected buffer mechanism 30 to move along the buffer moving track 14. The buffer base 31 of each buffer mechanism 30 is movably disposed on the buffer moving track 14. For example, the buffer moving member 15 is a cylinder or a motor. Under the drive of the buffer moving member 15, the multiple buffer mechanisms 30 can adjust their positions on the buffer moving track 14 so that each buffer mechanism 30 corresponds to the position of the first film-laying assembly 41 and the second film-laying assembly 42 respectively.

[0065] It is understood that in some embodiments, the distribution and movement directions of the multiple feeding mechanisms 20, the distribution and movement directions of the multiple buffering mechanisms 30, and the arrangement directions of the multiple sets of first film-laying components 41 and second film-laying components 42 are all in the third direction Y, so that multiple film strips 200 can be laid simultaneously in the third direction Y.

[0066] In some embodiments, the working principle of the film-laying device 100 is as follows: The user loads the wound film strip 200 onto the unwinding roller 22 of the feeding mechanism 20. While the feeding mechanism 20 unwinds the film strip 200, the first guide roller 33 of the buffer mechanism 30 takes the film strip 200 and winds it onto the buffer roller 32. Then, the film strip 200 is conveyed to the film laying mechanism 40 through the second guide roller 34. The user only needs to intervene when replacing the film strip 200. Driven by the first film-laying component 43, the first film-laying assembly 41 of the film-laying mechanism 40 moves along the film-laying track 11 toward the buffer mechanism 30. The user pulls the film strip 200 of the buffer mechanism 30 onto the first film-laying assembly 41 and clamps it. Then, the first film-laying assembly 41 moves along the film-laying track 11 away from the buffer mechanism 30 to the edge of the working surface 301 of the material 300. User intervention is only required when replacing the new film strip 200. Driven by the second film laying component 44, the second film laying component 42 moves along the film laying track 11 closer to the first film laying component 41, and then the second film laying component 42 takes over the head of the film strip 200 of the first film laying component 41 and clamps it. After the second film-laying assembly 42 clamps the head of the film belt 200, the first film-laying assembly 41 releases the film belt 200, and then the second film-laying assembly 42 moves along the film-laying track 11 away from the first film-laying assembly 41 to the other edge of the working surface 301 of the material 300. The first film-laying assembly 41, driven by the first film-laying moving part 43, and the second film-laying assembly 42, driven by the second film-laying moving part 44, descend synchronously to lay the film belt 200 onto the working surface 301 of the material 300, thus completing the laying.

[0067] In this application, the frame structure diagram of the frame 10 used to support the fixed feeding track 12, the buffer moving track 14 and the film laying track 11 is not shown.

[0068] In this application, the relative perpendicularity between the two does not mean an absolute 90° relationship, and the relative parallelism between the two does not mean an absolute 180° relationship. A certain deviation is allowed, as long as it does not obstruct the conveying of the film belt 200 between the feeding mechanism 20, the buffer mechanism 30 and the film laying mechanism 40.

[0069] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
