Description

Technical Field

[0001] This application relates to the field of adhesive film cutting technology, and in particular to an adhesive film cutting device. Background Technology

[0002] The current photovoltaic (PV) industry chain starts with upstream silicon raw materials, proceeds through metallic silicon refining, polycrystalline silicon preparation, silicon rod pulling, and silicon wafer cutting, to the midstream production of solar cells and PV modules, and finally integrates downstream into PV power plant systems. In this process, the design and manufacturing of PV modules is the heart of the solar power system, its core function being the efficient and stable conversion of captured solar energy into electrical energy. Completed PV modules, as a core component of the solar power system, can be flexibly applied in various scenarios: in off-grid systems, they can store the converted electrical energy in batteries for emergencies or to power independent loads; while in grid-connected systems, they can directly connect the electrical energy to the grid, realizing the widespread supply and utilization of clean energy.

[0003] The production process of photovoltaic modules involves multiple complex steps, including string welding, layout, stacking, lamination, glass bonding, EL (electrode optic) visual inspection, edge sealing, lamination, edge trimming, flipping inspection, frame assembly, and junction box welding. In the lamination process, it is necessary to periodically measure the lamination effect, with the encapsulant film crosslinking degree test being particularly important. The encapsulant film undergoes crosslinking under high-temperature conditions, and the crosslinking effect directly affects the reliability of the module; therefore, it is essential to measure the encapsulant film crosslinking degree.

[0004] To conduct this experiment, one 100mm x 100mm piece of the front and one 100mm piece of the back adhesive film need to be pre-cut and placed in the glass interlayer. These are then laminated together with the normal components in a laminator. After lamination, the glass is removed, revealing the fused front and back adhesive films. These then need to be manually cut into 2mm x 2mm pieces, followed by xylene extraction and drying to measure the degree of crosslinking. However, the manual cutting process is tedious and difficult, and it is challenging to accurately cut the films into 2mm x 2mm pieces; significant deviations can affect the accuracy of the crosslinking degree test results.

Detailed Implementation

[0039] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0040] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0041] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0042] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact, or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0044] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0045] The production process of photovoltaic modules involves multiple complex steps, including string welding, layout, stacking, lamination, glass bonding, EL (electrode optic) visual inspection, edge sealing, lamination, edge trimming, flipping inspection, frame assembly, and junction box welding. In the lamination process, it is necessary to periodically measure the lamination effect, with the encapsulant film crosslinking degree test being particularly important. The encapsulant film undergoes crosslinking under high-temperature conditions, and the crosslinking effect directly affects the reliability of the module; therefore, it is essential to measure the encapsulant film crosslinking degree.

[0046] To conduct this experiment, one 100mm x 100mm piece of the front and one 100mm piece of the back adhesive film need to be pre-cut and placed in the glass interlayer. These are then laminated together with the normal components in a laminator. After lamination, the glass is removed, revealing the fused front and back adhesive films. These then need to be manually cut into 2mm x 2mm pieces, followed by xylene extraction and drying to measure the degree of crosslinking. However, the manual cutting process is tedious and difficult, and it is challenging to accurately cut the films into 2mm x 2mm pieces; significant deviations can affect the accuracy of the crosslinking degree test results.

[0047] For this purpose, please refer to Figures 1 to 3 This application provides a novel film cutting device 100. Figure 1 This is a schematic diagram of a film cutting device 100 according to an embodiment of this application from one perspective. Figure 2 for Figure 1 A schematic diagram of the film cutting device 100 shown from another perspective. Figure 3 for Figure 1 Front view of the film cutting device 100 shown.

[0048] The encapsulant film cutting device 100 of this application is capable of cutting a test encapsulant film (not shown) to a target encapsulant film (not shown) of a predetermined size. This target encapsulant film of the predetermined size can be used for crosslinking degree testing. It is understood that crosslinking degree testing is necessary during the manufacturing process of photovoltaic modules to evaluate the degree of crosslinking reaction of the encapsulant film during the lamination process. The degree of crosslinking directly affects the mechanical strength, weather resistance, light transmittance, and long-term reliability of the module.

[0049] When preparing the test film, one front film and one back film of a predetermined size (e.g., 100mm × 100mm or other sizes) need to be cut in advance. The front and back films are placed in the glass interlayer and laminated together with the normal components in a laminator. After lamination, the glass is removed, resulting in the front and back films fused together. The fused front and back films are the test film referred to in this application.

[0050] After preparing the test film, a target film of a predetermined size needs to be cut from the central region of the test film. The test film may exhibit localized differences in cross-linking degree in larger areas (such as uneven temperature between the edges and center, thickness fluctuations, etc.). Cutting the target film into the central region (50mm × 50mm or other dimensions) eliminates the influence of edge effects and non-uniform areas, ensuring that the target film represents the average cross-linking state of the test film.

[0051] Furthermore, the preset size of the target adhesive film is 2mm × 2mm or other sizes. It is worth noting that the focus of this application is on how to cut the adhesive film to be tested into the target adhesive film of the predetermined size. The preparation of the adhesive film to be tested and how to conduct crosslinking degree tests on the target adhesive film are not the focus of this application and will not be discussed further below.

[0052] The film cutting device 100 of this application can automatically cut the film to be tested into a target film of a predetermined size without the need for manual cutting, thus reducing the complexity of the cutting process. At the same time, it can also ensure the accuracy of the cut size of the target film to meet the requirements of the crosslinking degree test, thereby ensuring the accuracy of the crosslinking degree test results.

[0053] See Figures 1 to 4 In one embodiment, the film cutting device 100 includes a conveying structure (not shown), a transfer structure 120, and a cutting structure 130. The conveying structure extends along its length and outputs movement along its length. The transfer structure 120 is disposed on the side of the conveying structure and is used to transfer the film to be tested onto the conveying structure, and moves with the conveying structure. The cutting structure 130 is disposed on the side of the conveying structure and spaced apart from the transfer structure 120. The conveying structure conveys the film to be tested to the cutting structure 130, and the cutting structure 130 cuts the film to be tested into a target film of a predetermined size. Figure 4 for Figure 1 A top view of the film cutting device 100 shown.

[0054] The conveyor structure is a component that transports the adhesive film to be tested. The conveyor structure is arranged along the length direction and is capable of transporting the adhesive film to be tested along this direction. For example... Figure 1 and Figure 2As shown, the left-right direction is the length direction, the front-back direction is the width direction, and the up-down and top-bottom directions are the height directions. These length, width, and height directions also apply to the film cutting device 100 and other components, and will not be elaborated upon further below.

[0055] The transfer structure 120 is a component for transferring the adhesive film to be tested, and the cutting structure 130 is a component for cutting the adhesive film to be tested into a target film of a predetermined size. The transfer structure 120 and the cutting structure 130 are disposed on the side of the conveying structure and are spaced apart along the length direction. The transfer structure 120 can transfer the adhesive film to be tested from a designated position to the conveying structure, the conveying structure transports the adhesive film to be cut to the cutting structure 130, and then the cutting structure 130 cuts the adhesive film to be tested.

[0056] After the cutting structure 130 cuts the test film into the target film, the target film is placed on the conveying structure, which transports the target film to the unloading position for subsequent crosslinking degree testing. After the conveying structure transports the previous test film to the cutting position, the transfer structure 120 can transfer the next test film to the conveying structure. This process is repeated continuously, enabling continuous transport of the test film and improving the cutting efficiency.

[0057] See Figures 1 to 4 In one embodiment, the transfer structure 120 and the cutting structure 130 are disposed on the same side. That is, the transfer structure 120 and the cutting structure 130 are located on the same side of the conveying structure, such as... Figure 1 and Figure 4 As shown, the transfer structure 120 and the cutting structure 130 are located on the rear side of the conveying structure.

[0058] Of course, in other embodiments of this application, the transfer structure 120 and the cutting structure 130 may also be located on the front and rear sides of the conveying structure, as long as the transfer structure 120 can transfer the test film and the cutting structure 130 can cut the test film.

[0059] The film cutting device of the above embodiment uses a transfer structure 120 to automatically transfer the film to be tested, and a conveying structure to automatically transport the film to the cutting structure 130. The cutting structure 130 then cuts the film to be tested into a target film of a predetermined size. This eliminates the need for manual cutting of the film to be tested into the target size, reducing the complexity of the cutting process. At the same time, it ensures the accuracy of the cut size of the target film to meet the requirements of the crosslinking degree test, thereby guaranteeing the accuracy of the crosslinking degree test results.

[0060] See Figures 1 to 4In one embodiment, the film cutting device 100 further includes a support base 140, on which the conveying structure, transfer structure 120, and cutting structure 130 are all disposed. The support base 140 serves as the base for the entire film cutting device 100. The support base 140 integrates and mounts each film cutting device 100, making the film cutting device 100 a single unit, facilitating its installation on a test platform or other surface. Optionally, the support base 140 is made of metal to improve its structural strength and achieve stable support.

[0061] See Figures 1 to 4 In one embodiment, the conveying structure includes a conveying drive (not shown), two conveyor pulleys (not shown), and a timing belt 110. The two conveyor pulleys are spaced apart along the length direction, and the timing belt 110 is sleeved on the conveyor pulleys. The conveying drive is connected to one of the conveyor pulleys to drive the conveyor pulleys to drive the timing belt 110 to convey the test film along the length direction.

[0062] The conveying drive unit is the power source for the conveying structure. Optionally, the conveying drive unit is a motor or the like. The axis of the conveyor pulleys extends along the width direction, and the two conveyor pulleys are spaced apart along the length direction on the support base 140. They are rotatably supported on the support base 140 by means of brackets or the like. The timing belt 110 is sleeved on the outside of the two conveyor pulleys and is the component for conveying the test film.

[0063] The conveyor drive unit is connected to one of the conveyor pulleys. When the conveyor drive unit drives the conveyor pulley to rotate, the rotation of the conveyor pulley drives the synchronous belt 110 to move along its length, thereby enabling the synchronous belt 110 to convey the test film along its length to the position of the cutting structure 130. It is worth noting that in Figures 1 to 4 The diagram only shows the synchronous belt 110; other components of the conveyor structure are not shown.

[0064] See Figures 1 to 4 In one embodiment, the film cutting device 100 further includes a first storage box 150. The first storage box 150 is located on the side of the conveying structure and is spaced apart from the transfer structure 120. The first storage box 150 is used to store the film to be tested. The first storage box 150 is disposed on the support base 140, located on the side of the conveying structure, and spaced apart from the transfer structure 120 along the length direction. Further, the first storage box 150 is located between the transfer structure 120 and the cutting structure 130. The film to be tested is stacked in the first storage box 150 to achieve storage and collection of the film to be tested.

[0065] When the transfer structure 120 transfers the adhesive film to be tested, it rotates from above the synchronous belt 110 to the first storage box 150 and extends into the first storage box 150 to retrieve one adhesive film to be tested. Subsequently, the transfer structure 120 rotates above the synchronous belt 110 and moves toward the synchronous belt 110 to place the adhesive film to be tested onto the synchronous belt 110. Thus, by storing and collecting the adhesive film to be tested in the first storage box 150, the transfer structure 120 can transfer the adhesive film to a designated position, facilitating the transfer of the adhesive film and improving the transfer efficiency.

[0066] See Figures 1 to 4 In one embodiment, the film cutting device 100 further includes a second storage box 160, which is located on the side of the conveying structure and spaced apart from the transfer structure 120. The second storage box 160 is used to store a carrier component (not shown), which is used to carry the film to be tested. It is understood that after the film to be tested is cut into a target film of a predetermined size, the size of the target film will be much smaller than the film to be tested. If the target film is placed directly on the synchronous belt 110, it is inconvenient to unload the target film.

[0067] Therefore, this application uses a carrier component to support the adhesive film to be tested, thereby enabling the carrier component to support the cut target adhesive film and directly achieve the unloading of the target component. Specifically, the transfer structure 120 first transfers the carrier component to the synchronous belt 110, and then transfers the adhesive film to be tested to the carrier component. At this time, the adhesive film to be tested is supported on the synchronous belt 110 by the carrier component. The synchronous belt 110 can transport the carrier component carrying the adhesive film to be tested to the cutting structure 130.

[0068] After the cutting structure 130 cuts the adhesive film to be tested, it can cut the adhesive film to be tested into target adhesive films of a preset size, namely adhesive film fragments, which are then loaded onto a supporting component. In this embodiment, the supporting component is a high-temperature cloth, that is, the adhesive film to be tested and the cut target adhesive film are supported by the high-temperature cloth. Of course, in other embodiments of this application, other materials can be used to support the adhesive film to be tested and the cut target adhesive film.

[0069] The second storage box 160 is located on the side of the conveying structure and is spaced apart from the transfer structure 120 along its length. Further, the second storage box 160 is located on the side of the transfer structure 120 away from the first storage box 150. The second storage box 160 stores stacked carrier components, the number of which is approximately equal to the number of adhesive films to be tested. Each adhesive film to be tested is carried by one carrier component.

[0070] In one embodiment, the size of the first storage box 150 is adapted to the size of the adhesive film to be tested. For example, the size of the first storage box 150 is 100mm × 100mm or other dimensions. In one embodiment, the size of the second storage box 160 is adapted to the size of the supporting component, which is slightly larger than the size of the adhesive film to be tested. For example, the size of the second storage box 160 is 120mm × 120mm or other dimensions. Optionally, both the first storage box 150 and the second storage box 160 are made of plastic material.

[0071] It is worth noting that the principle of the transfer structure 120 in transferring the test film is essentially the same as the principle of the transfer carrier component. The difference between the two is that the transfer component moves above the first storage box 150 or above the second storage box 160. When describing the specific structure and principle of the transfer structure 120 later, we will only use the transfer structure 120 in transferring the test film as an example.

[0072] See Figures 1 to 5 In one embodiment, the transfer structure 120 includes a first support column 121, a rotating assembly (not shown), a first moving assembly (not shown), and a transfer assembly (not shown). The first support column 121 is disposed on the side of the conveying structure along the height direction. The rotating assembly is disposed on the first support column 121 and extends toward the conveying structure. The output end of the rotating assembly is connected to the first moving assembly to drive the first moving assembly to rotate in the horizontal plane. The output end of the first moving assembly is connected to the transfer assembly, and the first moving assembly drives the transfer assembly to extend and retract along the height direction so that the transfer assembly transfers the film to be tested to the conveying structure. Figure 5 for Figure 1 A schematic diagram of the transfer structure 120 in the film cutting device 100 shown.

[0073] The first support column 121 is a support column of the transfer structure 120. The first support column 121 is disposed on the support base 140 and extends along the height direction. The rotating component is disposed on the first support column 121 and is located in the horizontal plane and can rotate in the horizontal plane. The rotating component can extend toward the direction of the conveying structure. The output end of the rotating component is connected to the first moving component.

[0074] The first moving component extends along the height direction and is directed toward the synchronous belt 110, and can be positioned above the synchronous belt 110. The transfer component is a structure for transferring the test film and the carrier component. The transfer component is located at the output end of the first moving component. The first moving component can drive the transfer component to move up and down along the height direction so that the transfer component can transfer the test film.

[0075] When transferring the test film, the rotating component drives the first moving component to rotate the transfer component in the horizontal plane, so that the first moving component and the transfer component are positioned above the first storage box 150. Subsequently, the first moving component drives the transfer component to descend in the height direction, so that the transfer component can remove the test film from the first storage box 150. Then, the first moving component drives the transfer component to rise in the height direction.

[0076] Subsequently, the rotating component drives the first moving component to rotate the transfer component and the test film in the horizontal plane, so that the first moving component moves the transfer component and the test film to above the synchronous belt 110. Then, the first moving component drives the transfer component to descend in the height direction, so that the transfer component places the test film onto the synchronous belt 110. Afterward, the first moving component drives the transfer component to reset, so as to facilitate the transfer of the next test film.

[0077] See Figures 1 to 5 In one embodiment, the rotating assembly includes a rotating component (not shown) and a first adapter rod 122 extending toward the conveying structure. The rotating component is disposed at the output end of the first support column 121, and the first adapter rod 122 is disposed at the output end of the rotating component and connected to the first moving component. The rotating component can drive the first adapter rod 122 to rotate the first moving component in a horizontal plane, so that the first moving component drives the transfer component to transfer the adhesive film to be tested.

[0078] The rotating component is the power source of the rotating assembly. The rotating component is fixedly mounted on the first support member. The output shaft of the rotating component extends along the height direction. The first adapter rod 122 is in the horizontal plane and is connected to the first adapter rod 122 radially along the output shaft of the rotating component. That is, the first adapter rod 122 extends radially along the output shaft of the rotating component. One end of the first adapter rod 122 is connected to the outer periphery of the output shaft of the rotating component, and the other end is connected to the first moving assembly.

[0079] In this way, when the rotating component outputs rotational motion, the rotating component can drive the first adapter rod 122 to rotate in the horizontal plane, thereby causing the first adapter rod 122 to move the first moving component and the transfer component to move above the first storage box 150, the second storage box 160 or the synchronous belt 110, so that the transfer component can transfer the test film and the carrier component onto the synchronous belt 110.

[0080] In this embodiment, the rotating component is a rotary motor, and the first adapter rod 122 is connected to the outer periphery of the rotating shaft of the rotary motor. Of course, in other embodiments of this application, a transmission wheel or the like may also be installed on the rotating shaft of the rotating component, and the first adapter rod 122 is connected to the transmission wheel.

[0081] The rotating component can drive the first adapter rod 122 to rotate 180°, thereby moving the first moving assembly and the transfer assembly above the first storage box 150, the second storage box 160, or the synchronous belt 110. It is worth noting that... Figures 1 to 5 Only the first adapter rod 122 is shown in the diagram; rotating components are not shown. Optionally, the first adapter rod 122 may be made of metal.

[0082] See Figures 1 to 5 In one embodiment, the first moving component includes a first moving part (not shown) and a first connecting rod 123. The first moving part is disposed at the end of the rotating component, the first connecting rod 123 extends along the height direction and is disposed at the output end of the first moving part, and the transfer component is disposed at one end of the first connecting rod 123. The first moving part can drive the first connecting rod 123 to drive the transfer component to move up and down along the height direction.

[0083] The first moving component is the power source for the first moving assembly. The first moving component is located at the end of the first adapter rod 122 away from the rotating component, and the first moving component is capable of outputting lifting and lowering motion along the height direction. The first connecting rod 123 extends along the height direction, with one end of the first connecting rod 123 connected to the output end of the first moving component and the other end of the first connecting rod 123 connected to the transfer assembly.

[0084] After the rotating component drives the first adapter rod 122 to move the first moving component and the transfer component to the corresponding positions, the first moving component drives the first connecting rod 123 to lower the transfer component in the height direction, so that the transfer component can contact the adhesive film to be tested in the first storage box 150 or place the adhesive film to be tested on the synchronous belt 110. Subsequently, the first moving component drives the first connecting rod 123 to raise the transfer component in the height direction, realizing the removal or release of the adhesive film to be tested.

[0085] It is worth noting that, in Figures 1 to 5 Only the first connecting rod 123 is shown in the diagram; the first moving component is not shown. Optionally, the first connecting rod 123 is made of metal. Optionally, the first moving component is a lifting cylinder or a linear motor, with its output end positioned along the height direction and connected to the first connecting rod 123.

[0086] In other embodiments of this application, the first moving component may also be a combination of a motor and a ball screw component. The ball screw component has a screw shaft connected to the output end of the motor, a screw nut disposed on the screw shaft and connected to the first connecting rod 123. When the motor drives the screw shaft to rotate, the screw shaft can drive the screw nut to rise and fall in the height direction, so that the screw nut drives the first connecting rod 123 to rise and fall in the height direction.

[0087] Of course, the first moving component can also be a combination of a motor and a gear and rack assembly. The gear is rotatably mounted on the motor and meshes with the rack, and the first connecting rod 123 is connected to the rack. When the motor drives the gear to rotate, the gear, through its meshing relationship, can drive the rack to move up and down in the height direction, so that the rack drives the first connecting rod 123 to move up and down in the height direction.

[0088] See Figures 1 to 5 In one embodiment, the transfer assembly includes an adsorption drive (not shown) and an adsorption member 124. The adsorption member 124 is disposed at the end of the first moving assembly and is connected to the adsorption drive through a negative pressure pipe. The adsorption drive can drive the adsorption member 124 to adsorb or release the adhesive film to be tested. In this embodiment, the transfer assembly uses adsorption to transfer the adhesive film to be tested.

[0089] The adsorption drive unit serves as the power source for the transfer assembly. The adsorption drive unit can be mounted on the support base 140, or on the first connecting rod 123 or the first adapter rod 122. The adsorption element 124 is located at the end of the first connecting rod 123 furthest from the first moving component. The adsorption element 124 is connected to the adsorption drive unit via a negative pressure pipe. Thus, the adsorption drive unit can apply negative pressure to the adsorption element 124, enabling it to adsorb the test film.

[0090] Specifically, when the rotating component drives the first adapter rod 122 to move the first moving component and the adsorption component 124 to above the first storage box 150, the first moving component drives the first connecting rod 123 to move the adsorption component 124 down in the height direction. When the adsorption component 124 comes into contact with the adhesive film to be tested, the adsorption driving component draws a negative pressure on the adsorption component 124 so that the adsorption component 124 adsorbs the adhesive film to be tested. The first moving component drives the first connecting rod 123 to move the adsorption component 124 and the adhesive film to be tested up.

[0091] Subsequently, the rotating component drives the first adapter rod 122 to move the first moving assembly and the adsorption component 124 above the synchronous belt 110. The first moving component drives the first connecting rod 123 to move the adsorption component 124 and the test film downwards along the height direction. After the test film is placed on the bearing component above the synchronous belt 110, the adsorption drive releases the negative pressure on the adsorption component 124. At this time, the adsorption component 124 no longer adsorbs the test film, completing the transfer of the test film. The first moving component drives the first connecting rod 123 to move the adsorption component 124.

[0092] Optionally, the adsorption driving component is a negative pressure source. Optionally, the adsorption component 124 is a suction cup. It is worth noting that... Figures 1 to 5 Only the adsorption element 124 is shown in the diagram; the adsorption drive element is not shown.

[0093] Of course, in other embodiments of this application, the transfer assembly includes a clamping drive and a clamping member. The clamping drive is disposed on the first moving assembly, and the clamping member is disposed at the output end of the clamping drive. The clamping drive can drive the clamping member to clamp or release the adhesive film to be tested. That is to say, the transfer assembly can also use a clamping method to transfer the adhesive film to be adsorbed.

[0094] The clamping drive is a clamping cylinder, and the clamping component has a structure similar to a clamp. The clamping drive is connected to the clamping component and can drive the clamping component to open or close, thereby enabling the clamping component to clamp or release the adhesive film to be tested, which also enables the transfer of the adhesive film to be tested. It is worth noting that the clamping drive and the clamping component can adopt the existing structure of clamping cylinders and clamps, and their structure and principle will not be described in detail here.

[0095] See Figures 1 to 3 , Figure 6 In one embodiment, the cutting structure 130 includes a second support column 131, a second moving component (not shown), and a cutting tool 133. The second moving component is disposed on the second support column 131. The output end of the second moving component is connected to the cutting tool 133 and drives the cutting tool 133 to extend and retract along the height direction so that the cutting tool 133 cuts the test film into the target film. Figure 6 for Figure 1 A schematic diagram of the cutting structure 130 in the film cutting device 100 shown.

[0096] The second support column 131 is the support column of the cutting structure 130. The second support column 131 is disposed on the support base 140 and extends along the height direction. The second moving component is disposed on the second support column 131 and located above the synchronous belt 110, extending along the height direction. The cutting blade 133 is the component for cutting the adhesive film to be tested. The cutting blade 133 is disposed at the output end of the second moving component, which can drive the cutting blade 133 to move up and down along the height direction, so that the cutting blade 133 can cut the adhesive film to be tested.

[0097] After the synchronous belt 110 transports the test film from the transfer structure 120 to below the cutting blade 133, the second moving component drives the cutting blade 133 to descend in the height direction. The cutting blade 133 enters the test film and cuts it into a target film of a preset size. After cutting, the second moving component drives the cutting blade 133 to rise in the height direction, completing the cutting of the test film.

[0098] See Figures 1 to 4 , Figure 6In one embodiment, the cutting structure 130 further includes a second adapter rod 134 extending in the width direction. The second adapter rod 134 is disposed on the second support column 131 and connected to the second moving assembly. The second adapter rod 134 is a support component to support the second moving assembly onto the second support column 131. The second adapter rod 134 extends in the width direction, with one end mounted to the second support column 131 and the other end connected to the second moving assembly, so that the second moving assembly is positioned above the timing belt 110. Optionally, the second adapter rod 134 is made of metal.

[0099] See Figures 1 to 4 , Figure 6 In one embodiment, the second moving component includes a second moving part (not shown) and a second connecting rod 132. The second moving part is disposed at the end of the second adapter rod 134. The second connecting rod 132 extends along the height direction and is disposed at the output end of the second moving part. The cutting tool 133 is disposed at one end of the second connecting rod 132. The second moving part can drive the second connecting rod 132 to move the cutting tool 133 up and down along the height direction.

[0100] The second moving component is the power source for the second moving assembly. The second moving component is located at the end of the second adapter rod 134 away from the second support column 131, and it is capable of outputting lifting and lowering motion along the height direction. The second connecting rod 132 extends along the height direction, with one end connected to the output end of the second moving component and the other end connected to the cutting tool 133.

[0101] When it is necessary to cut the test film, the second moving component drives the second connecting rod 132 to lower the cutting blade 133 in the height direction, so that the cutting blade 133 can contact the test film and cut it to cut the central area of ​​the test film into the target film. Subsequently, the second moving component drives the second connecting rod 132 to raise the cutting blade 133 in the height direction to complete the cutting of the test film.

[0102] It is worth noting that, in Figures 1 to 4 , Figure 6 Only the second connecting rod 132 is shown in the diagram; the second moving component is not shown. Optionally, the second connecting rod 132 is made of metal. Optionally, the second moving component is a lifting cylinder or a linear motor, with its output end positioned along the height direction and connected to the second connecting rod 132.

[0103] In other embodiments of this application, the second moving component may also be a combination of a motor and a ball screw component. The ball screw component has a screw shaft connected to the output end of the motor, a screw nut disposed on the screw shaft and connected to the second connecting rod 132. When the motor drives the screw shaft to rotate, the screw shaft can drive the screw nut to rise and fall in the height direction, so that the screw nut drives the second connecting rod 132 to rise and fall in the height direction.

[0104] Of course, the second moving component can also be a combination of a motor and a gear and rack assembly. The gear is rotatably mounted on the motor and meshes with the rack, and the second connecting rod 132 is connected to the rack. When the motor drives the gear to rotate, the gear, through its meshing relationship, can drive the rack to move up and down in the height direction, so that the rack drives the second connecting rod 132 to move up and down in the height direction.

[0105] See Figures 1 to 3 , Figures 6 to 8 In one embodiment, the cutting tool 133 includes a plurality of first blades (not shown) and a plurality of second blades (not shown), which are arranged alternately along the length and width directions. Adjacent first blades and adjacent second blades intersect to form a cutting area 1331, thereby creating a mesh-like plurality of cutting areas 1331. A second moving component can drive the cutting tool 133 to extend toward the conveying structure, so that the first and second blades cut the test film into a target film of a predetermined size. Figure 7 for Figure 6 The diagram shows the cutting tool 133 extending in the cutting mechanism. Figure 8 for Figure 7 The diagram shows the retraction of the cutting tool 133.

[0106] The first blade extends along its length, and multiple first blades are spaced apart along their width. The second blade extends along its width, and multiple second blades are spaced apart along their length. The multiple first blades and multiple second blades are staggered to give the cutting tool 133 a grid-like blade structure.

[0107] A cutting area 1331 is formed between two adjacent first blades and between two adjacent second blades, so that multiple first blades and multiple second blades can form multiple cutting areas 1331. That is, the cutting tool 133 is a grid blade with multiple cutting tools 133.

[0108] In this embodiment, the size of the cutting area 1331 is 2mm × 2mm. Of course, in other embodiments of this application, the size of the cutting area 1331 can be other sizes. Optionally, the size of the cutting tool 133 is 50mm × 50mm, so that the cutting tool 133 can cut the central area of ​​the adhesive film to be tested. Of course, the size of the cutting tool 133 can also be other sizes.

[0109] The size of the cutting area 1331 is the same as the preset size of the target adhesive film. When the cutting tool 133 cuts the adhesive film to be tested, each cutting area 1331 can cut out one target adhesive film. In this way, the cutting tool 133 can simultaneously cut the middle area of ​​the adhesive film to be tested into multiple target adhesive films, and the multiple target adhesive films are supported by the supporting component.

[0110] In this way, the cutting tool 133 can cut multiple target films of the same size at one time, eliminating the size deviation caused by manual cutting, ensuring the size accuracy of each target film, and thus ensuring the accuracy of the crosslinking degree test results of the target film.

[0111] Meanwhile, after the cutting tool 133 cuts out multiple target films at once, it can achieve efficient and non-destructive cutting of the films to be tested, significantly improving the cutting efficiency of the films to be tested, and is especially suitable for the large-scale testing needs of production lines or laboratories.

[0112] See Figures 1 to 3 , Figures 6 to 8 In one embodiment, the cutting structure 130 further includes a grid baffle 135. The grid baffle 135 includes a mounting frame 1351 and a plurality of protrusions 1352 disposed in the mounting frame 1351. The mounting frame 1351 is fixedly disposed on the second moving component. The plurality of protrusions 1352 are spaced apart in the mounting frame 1351 along the length and width directions. There is a preset gap between adjacent protrusions 1352. The preset gap is used to accommodate the first blade or the second blade so that the protrusions 1352 extend into the cutting area 1331 and push the test film away from the cutting tool 133.

[0113] The grid baffle 135 is fixed relative to the cutting blade 133. Understandably, the test film has a certain degree of adhesion; after the cutting blade 133 cuts the test film, small pieces of the target film will adhere to the first and second blades. Therefore, this application provides a grid baffle 135 on the outside of the cutting blade 133, allowing the cutting blade 133 to extend or retract relative to the grid baffle 135 in a movable manner along the height direction.

[0114] When the cutting tool 133 extends relative to the grid baffle 135, the cutting tool 133 can cut the film to be cut into multiple target films. Then, the cutting tool 133 retracts into the grid baffle 135. At this time, the grid baffle 135 will push away the target film remaining on the first blade and the second blade, so that the target film falls onto the supporting component, thus preventing the target film from remaining on the cutting tool 133.

[0115] Understandably, the grid baffle 135 can be fixed to the second support column 131 or the second moving component, and the second connecting rod 132 drives the cutting tool 133 to move relative to the grid baffle 135. Of course, the second connecting rod 132 can also be a telescopic rod, with the outer rod connected to the grid baffle 135 and the inner rod connected to the cutting tool 133. After the second connecting rod 132 drives the grid baffle 135 and the cutting tool 133 to descend simultaneously to a specified height, the second connecting rod 132 drives the inner rod to descend relative to the outer rod, so that the cutting tool 133 cuts the test film.

[0116] The grid baffle 135 includes a mounting frame 1351 and a plurality of protrusions 1352. The mounting frame 1351 is the border of the grid baffle 135. The plurality of protrusions 1352 are disposed in the mounting frame 1351, and are spaced apart along the length and width directions. The size of the protrusions 1352 is adapted to the size of the cutting area 1331. Furthermore, adjacent protrusions 1352 have a first gap along the width direction, which can accommodate a first blade, and adjacent protrusions 1352 have a second gap along the length direction, which can accommodate a second blade.

[0117] When the cutting tool 133 is located in the grid baffle 135, each protrusion 1352 is located in the corresponding cutting area 1331. At this time, each cutting area 1331 of the cutting tool 133 is set in a one-to-one correspondence with each protrusion 1352 of the grid baffle 135, and the protrusions 1352 can fill each cutting area 1331 of the cutting tool 133.

[0118] When the test film needs to be cut, the second moving component drives the second connecting rod 132 to extend the cutting blade 133 out of the grid baffle 135 (descending along the height direction). The cutting blade 133 contacts the test film and cuts the central area of ​​the test film into multiple target films. After cutting, the second moving component drives the second connecting rod 132 to retract the cutting blade 133 back into the grid baffle 135 (rising along the height direction). The protrusions 1352 in the grid baffle 135 push the target film remaining on the cutting blade 133 back to the supporting component, preventing the target film from adhering to the cutting blade 133.

[0119] Before operation, the film cutting device 100 of this application sequentially places the test films to be cut into the first storage box 150, and then places a corresponding number of supporting components in the second storage box 160, which support the multiple target films after cutting. After preparation is completed, the film cutting device 100 starts working.

[0120] After the film cutting device 100 is started, the rotating component drives the first adapter rod 122 to rotate the first moving component and the adsorption component 124 in the horizontal plane, so that the adsorption component 124 moves to the top of the second storage box 160. The first moving component drives the first connecting rod 123 to lower the adsorption component 124, so that the adsorption component 124 enters the second storage box 160 to adsorb the supporting component. The first moving component drives the first connecting rod 123 to raise the adsorption component 124 and the supporting component.

[0121] Subsequently, the rotating component drives the first adapter rod 122 to rotate the first moving assembly, the adsorption member 124, and the carrying component in the horizontal plane, so that the adsorption member 124 moves above the synchronous belt 110. The first moving component drives the first connecting rod 123 to lower the adsorption member 124 and the carrying component, so that the carrying component is placed on the synchronous belt 110. The first moving component drives the first connecting rod 123 to raise the adsorption member 124. Then, the above steps are repeated to adsorb a test film from the first storage box 150 and place the test film on the carrying component on the synchronous belt 110. Subsequently, the synchronous belt 110 starts, conveying the carrying component and the test film together to the area below the cutting blade 133.

[0122] At this time, the second moving component drives the second connecting rod 132 to lower the cutting blade 133. The cutting blade 133 contacts the central area of ​​the adhesive film to be tested and cuts the central area of ​​the adhesive film into multiple target adhesive films of preset sizes. To prevent the cut target adhesive films from adhering to the cutting blade 133, the second moving component drives the second connecting rod 132 to raise the cutting blade 133 so that the cutting blade 133 returns to the grid baffle 135. The protrusion 1352 in the grid baffle 135 can push the target adhesive films on the cutting blade 133 back onto the supporting component.

[0123] After cutting, the synchronous belt 110 restarts, conveying the supporting component to the unloading position at the tail of the synchronous belt 110. The operator only needs to remove the supporting component carrying multiple target films to proceed with subsequent operations. This film cutting device 100 significantly improves the efficiency of cutting the test films while ensuring the accuracy of the target film dimensions, thereby guaranteeing the accuracy of the crosslinking degree test results.

[0124] The adhesive film cutting device 100 of this application can automatically cut the adhesive film to be tested into several 2mm×2mm target adhesive films, thereby improving work efficiency and the accuracy of test results, reducing human error, and optimizing the operation process. This adhesive film cutting device 100 can quickly complete the cutting of the adhesive film, avoiding the tediousness of manual operation and improving work efficiency. Moreover, the adhesive film cutting device 100 ensures that the size of each small piece of target adhesive film is consistent through automatic and precise cutting, greatly improving the accuracy of measurement results. At the same time, after cutting the adhesive film to be tested using the adhesive film cutting device 100, the operator only needs to simply place the adhesive film to be tested and start the device, reducing complex manual steps and making operation convenient.

[0125] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0126] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
