Description

Technical Field

[0001] This utility model belongs to the field of material heating and bonding technology, specifically relating to a heating and pressing device and a hot pressing and bonding equipment. Background Technology

[0002] In the field of material heating and bonding technology, there is a need to bond film strips onto thin film materials. Currently, based on the aforementioned need, the commonly used hot-pressing bonding method in the prior art is the roller bonding method, which uses a heated roller to act on the film strip and the film, and the film strip is hot-pressed onto the film after the film strip and the film pass through the heated roller.

[0003] The hot-pressing and rolling method described above has significant limitations regarding the material requirements of the film and film strip. It is more suitable for lower melting temperatures. The limitations of the rolling method include: 1. When using the rolling method for hot pressing, the hot press head is in direct contact with the film strip, making it very easy for the film strip to stick to the hot press head after being heated; 2. When using the rolling method for hot pressing, the film strip is heated instantaneously. If the melting temperature of the film strip is high, the heating of the film strip may not meet the melting requirements, resulting in the film strip failing to adhere to the film material.

It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model. Furthermore, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0059] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0061] The heating and pressing device and hot pressing bonding equipment of this patent are applied in the photovoltaic field, mainly used to heat and bond film strips (such as black film strips) onto insulating films (that is, thin film materials below).

[0062] The following is for reference. Figures 1-7 The heating and pressing device according to a preferred embodiment of the present invention is described.

[0063] like Figure 1 As shown, the heating and pressing device in the preferred embodiment includes a carrying mechanism 1, a film strip feeding mechanism 3, a release film feeding mechanism 4, and a heating and pressing mechanism 5.

[0064] The supporting mechanism 1 is positioned directly opposite and below the hot-pressing mechanism 5, and is used to support the film material 201, such as EPE film, to be bonded to the film strip. The specific structure of the supporting mechanism 1 can be, for example, a belt conveyor mechanism with negative pressure adsorption function. Preferably, the surface of the belt conveyor mechanism is flat, and its width can cover the entire width of the film material 201 to be bonded to the film strip 303 at the current workstation. Furthermore, the surface of the belt conveyor mechanism is provided with adsorption holes to negatively adsorb the film material 201 onto the surface of the belt conveyor mechanism, preventing the position of the film material 201 from shifting during conveying, and the belt's transmission direction is the first direction.

[0065] Furthermore, the film material 201 of the film strip 303 to be bonded, which is carried on the bearing mechanism 1, can be provided by the film feeding mechanism 2 described below. The specific structure of the film feeding mechanism 2 and the method of providing the film material 201 are described in detail below.

[0066] Meanwhile, the film strip feeding mechanism 3 is used to provide multiple film strips 303 extending along a first direction or a second direction to the film material 201 on the carrying mechanism 1; wherein, the first direction is the feeding direction of the film material 201, and the second direction is perpendicular to the first direction. More preferably, the carrying mechanism 1 can transport the film material 201 after the film strips are bonded, and its transport direction is the first direction.

[0067] More specifically, in the preferred embodiment, the release film feeding mechanism 4 is used to feed the release film 403 onto the side of the film strip facing away from the film material 201, and the release film 403 separates each film strip 303 from the hot pressing mechanism 5. Meanwhile, in the preferred embodiment, the hot pressing mechanism 5 includes a displacement module 502 and a hot pressing head 501 connected to the displacement module 502. Driven by the displacement module 502, the hot pressing head 501 can be controlled to move vertically closer to or further away from the supporting mechanism 1, pressing the release film 403 and film strips 303 onto the film material 201, and heating and pressing the film strips 303 onto the film material 201 through the release film 403. The displacement module 502 can be a motor or a cylinder.

[0068] By utilizing the combination of the aforementioned mechanisms in the heating and pressing device, when the film strip 303 is hot-pressed onto the film material 201, the film strip 303 and the hot pressing head 501 can be separated by the release film 403, avoiding direct contact between the hot pressing head 501 and the film strip 303. This prevents the film strip 303 from sticking to the hot pressing head 501 after softening due to heat, ensuring the accuracy of hot-pressing the film strip 303 onto the film material 201.

[0069] Furthermore, for the heating and pressing device in the preferred embodiment, its release film feeding mechanism 4 preferably feeds the release film 403 in a winding and unwinding manner. In this case, the release film feeding mechanism 4 includes a release film unwinding module 401 and a release film winding module 402 respectively disposed on both sides of the bearing mechanism 1 in the first direction. Figure 2 As shown in the image.

[0070] The release film unwinding module 401 includes an unwinding unit 4011 for unwinding the release film 403, and the release film winding module 402 includes a winding unit 4021 for winding the release film 403. In the preferred embodiment, both the unwinding unit 4011 and the winding unit 4021 include a rotatably controllable film tray, on which unused and used release film 403 are stored in a wound form. Both the unwinding unit 4011 and the winding unit 4021 include a driving component to drive the film tray, such as a motor.

[0071] Meanwhile, the release film unwinding module 401 and release film winding module 402 in the preferred embodiments have similar structures, both including a pressing component, a tensioning component, and a lifting component, i.e. Figure 2 The first pressing assembly 4012 and the second pressing assembly 4022, the first tensioning assembly 4013 and the second tensioning assembly 4023, and the first lifting assembly 4014 and the second lifting assembly 4024 are shown in the diagram. After the release film is released from the unwinding unit 4011, it sequentially passes around the pressing assembly, tensioning assembly, and lifting assembly of the release film unwinding module 401 and then winds around the lifting assembly, tensioning assembly, pressing assembly, and winding unit 4021 of the release film winding module 402. By using the two tensioning assemblies to tension the release film 403, the release film 403 can have a better adhesion to the film strip 303 during heat bonding, thus improving the bonding effect of the film strip 303. In addition, by setting up two lifting components, it is convenient to ensure that the release film 403 is not attached to the film strip 303 when changing to the next set of film strips 303, but is attached to the film strip 303 when heat bonding is required; on the other hand, the setting of two lifting components also makes it easy to control the distance between the release film 403 and the hot press head 501. Furthermore, by setting up the release film winding module 402, the used release film 403 can be recycled.

[0072] Specifically, the two clamping assemblies are used to clamp the release film released between the unwinding unit 4011 and the winding unit 4021, respectively, to prevent the release film 403 from driving the driving components in the unwinding unit 4011 or the winding unit 4021 when it is raised or lowered. Specifically, the two clamping assemblies can at least clamp the section of release film 403 required for isolating the hot press head 501 and the film strip 303. The two tensioning assemblies are used to tension the release film 403 between the two clamping assemblies, and the tensioned release film 403 can be vertically raised or lowered under the drive of the two lifting assemblies, controlling the tensioned release film 403 to move closer to or away from the carrying mechanism 1.

[0073] More specifically, the two tensioning components each include a tensioning drive actuator and a tensioning roller connected to the tensioning drive actuator. The lifting component includes a lifting drive actuator and a lifting roller connected to the lifting drive actuator. The lifting drive actuator drives the lifting roller to move up and down so that the tensioned release film 403 moves closer to or further away from the support mechanism 1. During the lifting and lowering control of the tensioned release film 403, the tensioning drive actuator can move in coordination with the movement of the lifting drive actuator to ensure that the release film 403 remains in a tensioned state throughout the lifting and lowering process.

[0074] As one example, the tensioning drive actuator is a rodless cylinder with unidirectional air supply, ensuring the release film is constantly subjected to upward tension. The lifting drive actuator is, for example, a cylinder. When the cylinder of the lifting assembly drives the lifting roller to rise or fall, it in turn drives the release film to rise or fall. During descent, the cylinder output force is greater than the output force of the rodless cylinder of the tensioning assembly, causing the release film to descend; during ascent, the rodless cylinder of the tensioning assembly provides tension, allowing the release film to rise in an orderly manner. Of course, the structures of the tensioning and lifting assemblies are not limited to these; any structure that can respectively achieve its corresponding function is within the scope of protection of this application.

[0075] In practical use, the release film 403, used to separate the film strip 303 from the hot press head 501, can be used for hot pressing bonding of a single section of film strip 303. During this process, as the film strip 303 is bonded to the film material 201 and conveyed to the next station, and as the next section of film material 201 and the next section of film strip 303 are delivered, the release film 403 can also follow the unwinding and rewinding process. However, in specific use, when the release film 403 is in good condition, it can also be used for hot pressing bonding of multiple sections of film strip 303. Specifically, after one section of release film 403 is bonded, the process of bonding multiple sections of film material 201 to film strip 303 can be completed by controlling the release film 403 to rise and fall multiple times, thus improving the economic efficiency of using the release film 403.

[0076] In another embodiment, the heating and pressing device further includes a film feeding mechanism 2. As one configuration of the film feeding mechanism 2, in a preferred embodiment, the film feeding mechanism 2 preferably includes a film material unwinding module disposed on the upstream side of the carrying mechanism 1 in the first direction, used to feed the film material 201 to the carrying mechanism 1 along the first direction. Simultaneously, the feeding direction of the film strip feeding mechanism 3 is the same as that of the film feeding mechanism 2. Furthermore, the film strip feeding mechanism 3 includes multiple film strip unwinding modules spaced apart along a second direction. After the previously unwound film strip 303 adheres to the film material 201, the next time each film strip unwinding module can follow the film material unwinding module to continue feeding the film strip 303 in the first direction.

[0077] By utilizing the aforementioned arrangement of the film feeding mechanism 2 and the film strip feeding mechanism 3, the film material 201 without film strip 303 can be synchronously fed in the first direction with the film strip 303 to be heat-pressed and laminated. After completing the film strip lamination work of the previous segment of film material 201, when switching to a new segment, the film material 201 can drive the film strip 303 to unwind synchronously, i.e., the film strip 303 is passively unwound. At this time, there is no need to install a drive motor on the film strip unwinding module. For the case of multiple film strips being unwound synchronously, this arrangement can eliminate the need for multiple film strip unwinding drive mechanisms, saving costs and space, and facilitating the layout of each mechanism.

[0078] In the case where the membrane strip 303 and the film material 201 are fed simultaneously, such as Figure 1 As shown, in this embodiment, the film strip feeding mechanism 3 does not require a film strip cutting assembly. After the initial hot pressing is completed, the subsequent film strip stretching operation is completed by the conveying of the film material 201. The cutting of the film strip 303 can be completed by the subsequent film material 201 cutting mechanism 400.

[0079] In another embodiment, the heating and pressing device further includes a film feeding mechanism 2. As another configuration of the film feeding mechanism 2, the film feeding mechanism 2 includes a sheet film material conveying module for feeding the sheet-shaped film material 201 along a first direction to the carrying mechanism 1. The structure of the sheet film material conveying module can be the same as that of the carrying mechanism 1, or it can be other conventional structures in the prior art, as long as it can deliver the sheet material to the carrying mechanism 1. In this case, the film strip feeding mechanism 3 preferably includes two configurations:

[0080] Firstly, the film strip feeding mechanism 3 includes a plurality of film strip unwinding modules spaced apart in a second direction. The film strip unwinding modules are used to feed the film strip 303 onto the sheet-like film material 201 along the first direction. In this case, the feeding direction of the film material 201 is the same as the feeding direction of the film strip 303.

[0081] Secondly, the film strip feeding mechanism 3 includes a plurality of film strip unwinding modules spaced apart in a first direction. The film strip unwinding modules are used to feed the film strip 303 onto the sheet-like film material 201 in a second direction. In this case, the feeding direction of the film material 201 is perpendicular to the feeding direction of the film strip 303.

[0082] More specifically, in the actual setting of the film strip feeding mechanism 3, its film strip unwinding module is preferably a film strip roll 301 with film strip 303 wound on it, and a film strip tensioning component 302, a film strip pulling component 305 and a film strip cutting component 304 are provided corresponding to the film strip roll 301. Among them, the film strip pulling component 305 is used to feed the film strip 303 to the film material 201 along the first direction or the second direction after clamping the end of the film strip 303, the film strip cutting component 304 is used to cut the film strip 303 after it is pulled into place and pressed, and the film strip tensioning component 302 is used to ensure that the film strip 303 fed onto the film material 201 is always in a tensioned state. In the case of feeding film strips 303 onto the pre-cut sheet film material 201, the film strip feeding mechanism 3 in the preferred embodiment completes the accurate feeding of multiple film strips 303 onto the film material 201 through the cooperation of the film strip roll 301, the film strip tensioning assembly 302, the film strip pulling assembly 305, and the film strip cutting assembly 304. Figure 7 As shown, Figure 7 In the example shown, the feeding direction of the film material 201 is perpendicular to the feeding direction of the film strip 303.

[0083] Furthermore, the release film 403 released by the release film unwinding unit in the release film feeding mechanism 4 can be either a whole sheet covering the width of each film strip 303, or multiple release films 403. When multiple release films 403 are in the form of release films, their extension direction is the same as the extension direction of the film strips 303 adhered to the film material 201. In other words, the release film 403 released by the release film feeding mechanism 4 only needs to ensure that the release film 403 and the film strips 303 are vertically aligned, thereby using the release film 403 to separate the film strips 303 from the heat pressing mechanism 5, avoiding direct contact between the heat pressing head 501 and the film strips 303.

[0084] Further, in the preferred embodiment, the hot pressing head 501 includes a plurality of hot pressing units 5011 disposed at its bottom. The extending direction of each hot pressing unit 5011 is parallel to the feeding direction of the film strip 303, and is vertically aligned with the film strip 303 during bonding. Preferably, the width of each hot pressing unit 5011 is not less than the width of the film strip 303, so that each film strip 303 can be pressed onto the film material 201 by the hot pressing unit 5011 through the release film 403, and the bonding of the film strip 303 to the film material 201 is completed after heating.

[0085] More in detail, such as Figure 4As shown in the preferred embodiment, each hot-pressing unit 5011 is respectively provided with a heating tube 5013 and a thermocouple 5012. The heating tube 5013 is located inside the hot-pressing unit 5011, and the bottom surface of the hot-pressing unit 5011 faces the release film 403. The heating tube 5013 is used to heat the hot-pressing unit 5011, and the thermocouple 5012 monitors the temperature of the hot-pressing unit 5011.

[0086] for Figure 4 The hot pressing unit 5011 extends in the horizontal direction shown in the figure. Let this horizontal direction be the first direction. Then, the hot pressing head 501 is suitable for hot pressing the film strip 303 fed along the first direction.

[0087] And for Figure 6 Regarding the hot pressing unit 5011 shown, the hot pressing unit 5011 extends in a direction perpendicular to the paper surface. Let the horizontal direction in the diagram be the first direction. In this case, the hot pressing head 501 extends in a second direction, which is suitable for situations where the film strip 303 is fed in the second direction. It can also be seen that multiple hot pressing units 5011 in the first direction are spaced apart, allowing for synchronous hot pressing of multiple film strips 303 spaced apart in the first direction.

[0088] Furthermore, in the preferred embodiment, the displacement module 502 of the hot-pressing mechanism 5 preferably includes a lifting electric cylinder 5021, a lifting guide assembly 5022, and a hot-pressing buffer assembly 5023, such as... Figure 4 , Figure 6 As shown in the figure. The top of the hot press head 501 is connected to the hot press buffer assembly 5023, the top of the hot press buffer assembly 5023 is connected to the bottom of the lifting guide assembly 5022, and the top of the lifting guide assembly 5022 is connected to the output end of the lifting electric cylinder 5021.

[0089] More specifically, the hot-pressing buffer assembly 5023 includes a plurality of elastic buffers arranged at intervals in a plane for providing cushioning when the hot-pressing head 501 sequentially presses the release film 403 and the film strip 303 onto the surface of the film material 201, wherein the elastic buffers are, for example, springs; the axis of the lifting cylinder 5021 extends vertically, and the lifting guide assembly 5022 is connected to the output shaft of the lifting cylinder 5021.

[0090] Furthermore, in the preferred embodiment, the supporting mechanism 1 can preferably be a belt conveyor mechanism with negative pressure adsorption function. The belt surface of the belt conveyor mechanism is provided with adsorption holes, and the conveying direction of the belt is the first direction. By using the adsorption and movement of the film material 201 by the belt conveyor mechanism, the alignment and feeding of the film material 201 below the hot pressing mechanism 5 is completed.

[0091] As an example, when both the film material 201 and the film strip 303 are fed in the first direction, the film feeding mechanism 2 and the film strip feeding mechanism 3 are arranged on the same side of the carrying mechanism 1 along the first direction. In this case, it is preferable to arrange a clamping roller conveying mechanism 300 on the other side of the carrying mechanism 1 away from the film feeding mechanism 2 and the film strip feeding mechanism 3. The clamping roller conveying mechanism 300 includes a pair of rotating rollers, so that the film material 201 after the hot-pressed film strip 303 is completed can be clamped by the two rotating rollers. The film material 201 after the hot-pressed film strip 303 is conveyed by the rotation of the two rotating rollers, and the film strip 303 and the film material 201 are fed in this process.

[0092] The heating and pressing device in the above embodiments is mainly used to bond the film strip 303 extending in one direction to the film material 201. However, in actual use, there is also a need for the pattern of the film strip 303 on the film material 201 to be a cross-sectional and cross-sectional mesh structure. In this case, the final film product is as follows: Figure 8 As shown, the film material 201 has multiple transverse and longitudinal strips 303 arranged side by side. Meanwhile, considering factors such as installation space, ease of maintenance, and work efficiency, as another aspect of this utility model, a hot-press bonding device is also proposed based on the aforementioned heating and pressing device.

[0093] Specifically, in the preferred embodiment, the hot-pressing lamination equipment includes a first heating and pressing device 100 and a second heating and pressing device 500 spaced apart at the rear end of the first heating and pressing device 100. The two heating and pressing devices are separately arranged at two workstations, and the extension directions of the film strips 303 laminated at the two workstations are perpendicular. By sequentially arranging the two heating and pressing devices, two film strips 303 with different extension directions can be hot-pressed onto the surface of the film material 201, forming a film strip 303 with different extension directions on the film material 201. Figure 8 The pattern.

[0094] Specifically, in the preferred embodiment, the first heating and pressing device 100 is used for heat-pressing and bonding the film strip 303 extending along the first direction (i.e., Figure 8 The longitudinal black film strip in the first heating and pressing device 500 is used to continue to heat-press and bond the film strip 303 extending in the second direction (i.e., the film strip 303 in the second direction) onto the surface of the film material 201 output from the first heating and pressing device 100. Figure 8 (the horizontal black film strips in the middle), and eventually form as shown in the figure. Figure 8 The membrane product shown.

[0095] Both heating and pressing devices include a support mechanism 1 for carrying film material 201, a film strip feeding mechanism 3 for providing film strips to the film material 201 on the support mechanism 1, a heating and pressing mechanism 5 for hot-pressing the film strip 303 onto the surface of the film material 201 carried on the support mechanism 1, and a release film feeding mechanism 4 for providing a release film 403 between the heating and pressing mechanism 5 and the film strip 303. The heating and pressing mechanism 5 is located above the support mechanism 1, and the support mechanism 1 of both heating and pressing devices conveys the film material 201 along a first direction. The structure of the support mechanism 1 can be the same as that in the above embodiment.

[0096] Meanwhile, the first heating and pressing device 100 also includes a first film feeding mechanism, which includes a film material unwinding module and a film unwinding roll, used to release unbonded film material 201 along the first direction; and the film strip feeding mechanism 3 of the first heating and pressing device 100 includes multiple film strip unwinding modules arranged side by side and spaced apart along the second direction, used to release multiple first film strips (longitudinal film strips) along the first direction. During conveying, the film material 201 bonded with the first film strip moves synchronously with the film strip unwinding module, releasing the next section of the first film strip to be bonded.

[0097] More specifically, a buffer device 200 and a cutting mechanism 400 are also provided between the first heating and pressing device 100 and the second heating and pressing device 500. The buffer device 200 is close to the first heating and pressing device 100 and is used to buffer the film material that has completed the first film strip heat pressing. By setting the buffer device 200, the front and rear cycle times can be adjusted. At the same time, the cutting mechanism 400 is used to cut the film material into single-piece film material units. Meanwhile, the second heating and pressing device 500 also includes a second film feeding mechanism for conveying the film material units. The output end of the second film feeding mechanism is connected to the input end of the carrier mechanism 1 of the second heating and pressing device 500, so that the film material units can be fed onto the carrier mechanism 1 below the heat pressing mechanism of the second heating and pressing device 500. The second film feeding mechanism has the same structure as the carrier mechanism 1, or it can be other conventional structures in the prior art, as long as it can feed the sheet material onto the carrier mechanism 1.

[0098] Furthermore, the film strip feeding mechanism 3 of the second heating and pressing device 500 includes multiple film strip unwinding modules arranged side-by-side at intervals along the first direction, used to release multiple second film strips (transverse film strips) along the second direction. The heat pressing mechanism 5 of the second heating and pressing device 500 can heat-press and adhere the second film strips to the surface of the film material unit on which the first film strips have already been adhered, with the release film 403 in between. The second direction is perpendicular to the first direction. After the heat pressing and adhesion of the second film strips is completed, the following can be obtained: Figure 8 The membrane product shown.

[0099] In the hot-pressing lamination equipment of this embodiment, since a release film 403 is introduced between the film strip 303 and the hot-pressing mechanism 5, the release film 403 separates the hot press head 501 of the hot-pressing mechanism 5 from the film strip 303, avoiding the film strip 303 from sticking to the hot press head 501 after being heated on the film due to direct contact between the hot press head 501 and the film strip 303, thus ensuring the reliability of the hot-pressing lamination of the film strip 303 on the film material 201. Furthermore, since one end of the film material 201 in the first heating and pressing device 100 is not cut off and is still wrapped around the film material unwinding module, the film material 201 has a certain tension, which prevents it from wrinkling. Moreover, only one direction of correction is needed to ensure the positional accuracy of the film material 201. In addition, since the conveying direction of the film material 201 in the first heating and pressing device 100 is the same as the feeding direction of the film strip 303, the film strip in the first heating and pressing device 100 can be passively unwound after being attached to the previous section of film material 201. That is, the film strip 303 is pulled out when the film material 201 moves. There is no need to set a drive actuator such as a drive motor in the film strip unwinding module. Since the film strip feeding mechanism 3 includes multiple film strip unwinding modules, this can save costs and facilitate layout.

[0100] More specifically, in the preferred embodiment, the second heating and pressing device 500 further includes a correction mechanism 6 for adjusting the alignment of the film material 201 unit on the carrier mechanism 1. The carrier mechanism 1 of the second heating and pressing device 500 is connected to the correction mechanism 6 to achieve alignment between the film material 201 unit and the second film strip. During operation, the position of the carrier mechanism 1 on the horizontal plane is adjusted by the correction mechanism 6, thereby adjusting the position of the film material 201 on the horizontal plane.

[0101] In actual setup, the bearing mechanism 1 can both provide a bearing function for the film material unit and transport the film material unit along the first direction. Additionally, the correction mechanism 6 in the embodiment can also be a conventional structure in the prior art, such as including three cylinders arranged in a triangle on the same horizontal plane, two of which control displacement in the first direction and the other controls displacement in the second direction, with the first direction perpendicular to the second direction. Simultaneous movement of all three cylinders can adjust the angle. Of course, the correction mechanism 6 is not limited to this example; it enables the adjustment of the film material unit's XYθ within the plane, completing the alignment of the film material unit.

[0102] Furthermore, to provide the power to transport the film material downstream, a clamping roller conveying mechanism 300 is preferably provided between the cutting mechanism 400 and the buffer device 200. The clamping roller conveying mechanism 300 is used to clamp the film material after the first film strip pressing is completed and transfer it to the cutting mechanism 400. At this time, the arrangement of the hot press laminating equipment is as follows: Figure 9As shown in the figure. The specific structure of the clamping roller conveying mechanism 300 is a conventional structure of the prior art. For example, as one example, it includes two rollers spaced apart, with a small gap between the two rollers for the thin film material with the first film strip attached to pass through, and the thin film material is moved downstream by driving one of the rollers to move.

[0103] It should be noted that the cutting mechanism 400 mentioned above is also a conventional structure in the prior art, which can cut the film material attached to the first film strip from the first film strip, and will not be described in detail here.

[0104] It is understandable that, in actual setup, the feeding methods of the film material 201 and film strip 303 in the two heating and pressing devices, as well as the feeding form of the release film 403, can be optimized as needed.

[0105] In one specific embodiment, the mechanisms in the first heating and pressing device 100 are arranged as follows:

[0106] The film strip feeding mechanism 3 includes multiple film strip unwinding modules spaced apart in a second direction. Each unwinding module is used to feed a first film strip along a first direction, thus enabling the feeding of multiple first film strips in the first direction. Simultaneously, the release film feeding mechanism 4 also includes multiple release film take-up and unwinding modules spaced apart in a second direction. The arrangement of each release film take-up and unwinding module is as follows: Figure 2 As shown, the first release films are fed along the first direction, i.e., multiple first release films are fed along the first direction, so that each first film strip can be vertically aligned with a first release film. In addition, the hot pressing mechanism 5 preferably includes a plurality of hot pressing units 5011 spaced apart along the second direction. Each hot pressing unit 5011 extends along the first direction and can hot press each first film strip onto the film material 201 after aligning its release film.

[0107] In another specific embodiment, the mechanisms in the second heating and pressing device 500 are arranged as follows:

[0108] The film strip feeding mechanism 3 includes multiple film strip unwinding modules spaced apart in a first direction, each module feeding a second film strip along a second direction. Simultaneously, the release film feeding mechanism 4 feeds a second release film along the first direction. The second release film is preferably a single, complete release film, with its width in the second direction not less than the length of the second film strip along that direction. Furthermore, the heat-pressing mechanism 5 in the second heating and pressing device 500 includes multiple heat-pressing units 5011 spaced apart in the first direction. Each heat-pressing unit 5011 extends along the second direction and can be aligned with each second film strip through the second release film. The heat-pressing bonding of multiple second film strips is then completed under the control of the displacement module 502. Figure 5 As shown in the image.

[0109] In the aforementioned hot-pressing laminating equipment, the first heating and pressing device 100 feeds the film material 201 and the first film strip in the first direction, and the second heating and pressing device 500 completes the hot-pressing lamination of the second film strip onto the sheet-like film material unit. This configuration can fully balance the continuity of operation with the convenience of cost and space layout, making it the preferred solution for the actual installation of hot-pressing laminating equipment.

[0110] Furthermore, the release film feeding mechanism 4 of both heating and pressing devices includes an unwinding module and a rewinding module respectively located on both sides of their corresponding bearing mechanism 1.

[0111] The unwinding module includes an unwinding unit 4011 for unwinding the release film 403, and the winding module includes a winding unit 4021 for winding the release film 403. Both the unwinding and winding modules include a pressing component, a tensioning component, and a lifting component. After being unwound from the unwinding unit 4011, the release film 403 sequentially passes through the pressing component, tensioning component, and lifting component of the unwinding module, and then winds through the lifting component, tensioning component, pressing component, and winding unit 4021 of the winding module. Simultaneously, two pressing components are used to press the release film 403 released between the unwinding unit 4011 and the winding unit 4021, respectively. Two tensioning components are used to tension the release film 403 between the two pressing components. The tensioned release film 403 can be vertically raised and lowered under the action of the two lifting components, controlling whether the tensioned release film 403 moves closer to or further away from the supporting mechanism 1.

[0112] More specifically, the unwinding unit 4011, the winding unit 4021, the pressing assembly, the tensioning assembly, and the lifting assembly in the release film feeding mechanism 4 of the two heating and pressing devices can be found in the description of the release film feeding mechanism 4 in the aforementioned heating and pressing device embodiment. The main difference is that the two release film feeding mechanisms 4 need to be adaptively adjusted according to the different extension directions of the film strips 303 attached in the two heating and pressing devices.

[0113] Furthermore, in the hot pressing bonding equipment, the hot pressing mechanism 5 in the two heating pressing devices can also refer to the description of the hot pressing mechanism 5 in the aforementioned heating pressing device embodiment. The main difference is that the two hot pressing mechanisms 5 need to be adaptively adjusted according to the different extension directions of the film strips 303 in the two heating pressing devices.

[0114] Meanwhile, in the hot-pressing laminating equipment, the film strip feeding mechanism 3 of the second heating and pressing device 500 also includes a film strip tensioning component 302, a film strip pulling component 305, and a film strip cutting component 304 disposed on the release path of the film strip 303. The film strip tensioning component 302 is used to tension the second film strip during transmission; the film strip pulling component 305 is used to feed the second film strip along a second direction after clamping its end; and the film strip cutting component 304 is used to cut the second film strip after it has been pulled into place and pressed. In the case of feeding film strips 303 to the pre-cut sheet film material 201, the film strip feeding mechanism 3 in the preferred embodiment completes the accurate feeding of multiple film strips 303 on the film material 201 through the cooperation of the film strip roll 301 with the film strip tensioning component 302, the film strip pulling component 305, and the film strip cutting component 304.

[0115] For the hot-press bonding equipment in the aforementioned preferred embodiment, its working process is preferably as follows:

[0116] The film material 201 and the first film strip are fed into the first heating and pressing device 100. Simultaneously, the release film 403 is fed through the release film feeding mechanism 4 of the first heating and pressing device 100. The tensioning component controls the tensioning of the release film 403, and the lifting component controls its raising and lowering. The heating and pressing mechanism 5 of the first heating and pressing device 100 is activated, causing the heating head 501 to descend. The heating head 501 presses the release film 403 and the first film strip onto the film material 201 on the supporting mechanism 1. The heating control of the heating head 501 achieves heat-press bonding between the first film strip and the film material 201. Subsequently, the hot press head 501 and release film 403 of the first heating and pressing device 100 are raised, and the film material 201 after the first film strip is bonded is transferred to the buffer device 200 and passes through the clamping roller conveying mechanism 300. Driven by the clamping roller conveying mechanism 300, the film material 201 is conveyed and the first film strip is passively fed, thereby pulling the next section of film material 201 to be heat-pressed and bonded and the first film strip onto the bearing mechanism 1 of the first heating and pressing device 100 until the first film strip and film material 201 to be pressed are aligned with the release film 403 above (at this time, the release film 403 can be a new release film 403 after rewinding or the release film 403 after the first heat pressing). After that, the release film 403 and the hot press head 501 are lowered again to complete the bonding of the first film strip on the next section of film material 201.

[0117] The film material 201 output by the clamping roller conveying mechanism 300 is fed to the cutting mechanism 400, where the cutting mechanism 400 cuts the film material 201 after the first film strip is pressed into film material units of a certain length. The second film feeding mechanism of the second heating and pressing device 500 receives the cut film material units and feeds them to the carrying mechanism 1 of the second heating and pressing device 500, while controlling the correction mechanism 6 to correct and position the film material units. Then, the second film strip is fed, moving along the second direction above the film material unit, and the second release film feeding mechanism in the second heating and pressing device 500 controls the feeding, tensioning, and lifting of the release film. Afterward, the hot pressing mechanism 5 of the second heating and pressing device 500 is controlled to operate, hot-pressing multiple second film strips extending along the second direction through the release film onto the surface of the film material unit that has completed the first film strip bonding, ultimately obtaining... Figure 8 The membrane product shown.

[0118] By utilizing the hot-pressing laminating equipment in the preferred embodiment described above, the film strips can be arranged in a crisscross pattern on the surface of the film material 201, ultimately resulting in the following... Figure 8 The film product shown is an example. However, depending on the actual setup requirements, the combination of the heating and pressing device can be modified to form a heat-pressing lamination device different from that in the aforementioned embodiments.

[0119] For example, in a preferred embodiment, the film material 201 fed in the first heating and pressing device 100 is a pre-cut sheet material. In this case, all the aforementioned mechanisms for feeding the film material 201 need to be replaced with mechanisms for feeding sheet materials, such as an adsorption conveying mechanism or a lateral clamping feeding mechanism. At the same time, the clamping roller conveying mechanism 300 and the cutting mechanism 400 for the film material 201 and the first film strip can also be eliminated accordingly.

[0120] Furthermore, the film strip feeding mechanism 3 in the first heating and pressing device 100 can feed the first film strip in either a first direction or a second direction. Correspondingly, the direction of feeding the second film strip in the second heating and pressing device 500 is perpendicular to the feeding direction of the first film strip. Thus, as with the heat-pressing bonding equipment in the aforementioned embodiments, the process can be completed... Figure 8 The manufacturing of the membrane product shown or similar membrane products (where the order of bonding the transverse and longitudinal membrane strips to the film material 201 is different, with the transverse membrane strips being pasted first and then the longitudinal membrane strips being pasted) is described.

[0121] The heating and pressing device of this utility model introduces a release film between the film strip and the heating and pressing mechanism. The release film separates the heating head of the heating and pressing mechanism from the film strip, avoiding the film strip from sticking to the heating head after being heated due to direct contact between the heating head and the film strip. This ensures the reliability of the film strip's heat-pressing bonding on the film material and improves the efficiency and quality of the film strip's heat-pressing bonding on the film material.

[0122] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
