Therefore, when the laminating roller rolls on the two stacked membranes, more areas of the membrane surface can be subjected to the extrusion of the laminating roller to better extrude the air between the two membranes, thereby reducing the bubbles after the two membranes are laminated.

[0008] In some alternative embodiments, the second frame body comprises a mounting plate, and the compression roller is rotatably connected to the mounting plate; and one side of the mounting plate is provided with a connecting rod.

[0009] The first frame body is provided with a through hole, and the connecting rod is slidingly arranged in the through hole; one end of the elastic member abuts against the mounting plate, and the other end abuts against the first frame body.

[0013] In some alternative embodiments, the connecting rod is threadedly connected to the mounting plate.

[0014] In the above technical solution, since the connecting rod is threadedly connected to the mounting plate, on the one hand, the connecting rod and the mounting plate are convenient to disassemble and assemble, and on the other hand, the maximum distance between the second mounting frame and the first mounting frame can be adjusted by screwing or unscrewing the connecting rod, and thus the degree of extrusion of the compression roller on the laminating roller can be changed.

[0015] In some alternative embodiments, the elastic member is sleeved on the connecting rod, and one end of the elastic member is in contact with the first frame body, and the other end is in contact with the mounting plate.

[0017] In some alternative embodiments, the compression assembly comprises two compression rollers arranged side by side on the mounting plate, and the two compression rollers are in contact with the laminating roller.

[0018] In the above technical solution, each compression assembly comprises two compression rollers arranged side by side, and the compression rollers are in contact with the laminating roller, so that the laminating roller can be better applied with a force, and the laminating roller can be more fully in contact with the film to be laminated, so as to reduce the air bubbles between the two laminated films.

[0022] In the above technical solution, a compression assembly is arranged every 200-500 mm in the axial direction of the laminating roller, so that the laminating roller can more fully contact the film to be laminated, thereby reducing the bubbles between the two laminated films.

[0023] In some alternative embodiments, the laminating roller is a silica gel structural member or a polyurethane structural member.

[0024] In the above technical solution, the laminating roller is a silica gel structural member or a polyurethane structural member, so it has good flexibility and is more easily deformed under the action of the compression roller, thereby more fully contacting the film to be laminated to reduce the bubbles between the two laminated films.

[0036] This application provides a bonding device for bonding two films in small-batch production. It features a simple structure, ease of operation, and low cost. For example, the bonding device provided can be used in the research and development of PEM water electrolyzers or fuel cell membrane electrodes; of course, it can also be applied to small-batch production in other scenarios.

[0037] like Figure 1 As shown, the bonding device provided in this application embodiment includes a first frame 110, a bonding roller 120 connected to the first frame 110, and a pressing assembly 200. The bonding roller 120 applies pressure to two stacked films to bond them together. For example, the bonding roller 120 is rotatably connected to the first frame 110, and is used to roll over the upper surface of the upper film, thereby bonding the two stacked films. The pressing assembly 200 applies force to the bonding roller 120, thereby enabling the bonding roller 120 to better contact the surface of the film as it rolls over it.

[0038] In some implementations, such as Figure 1 As shown, the first frame 110 has a "U" shaped structure, including a base plate 111 and two first side plates 112. The two first side plates 112 are disposed at both ends of the base plate 111 and are located on the same side of the base plate 111. The two ends of the bonding roller 120 are respectively rotatably connected to one of the first side plates 112. Furthermore, a bearing can be provided between the end of the bonding roller 120 and the first side plate 112 to facilitate the rotation of the bonding roller 120.

[0039] Furthermore, the pressing assembly 200 includes a second frame, a pressing roller 220, and an elastic element 230. The first frame 110 is movably connected to the second frame, and the pressing roller 220 is rotatably connected to the second frame. Therefore, the pressing roller 220 can also move relative to the first frame 110 and the bonding roller 120. Since the elastic element 230 is compressed and abuts against the first frame 110 at one end and against the second frame at the other end, the second frame can bring the pressing roller 220 into contact with the bonding roller 120 under the action of the elastic element 230. The elastic force of the elastic element 230 can be transmitted to the bonding roller 120 through the second frame and the pressing roller 220, thereby enabling the bonding roller 120 to better contact the film to be bonded. When the bonding roller 120 rolls over the two stacked films, more areas of the film surface can be squeezed by the bonding roller 120 to better squeeze out the air between the two films, thereby reducing air bubbles that appear after the two films are bonded.

[0040] Furthermore, the pressing roller 220 is arranged parallel to the bonding roller 120. Therefore, during the rolling process of the bonding roller 120, the pressing roller 220 can rotate together with the bonding roller 120, which reduces the friction between the pressing roller 220 and the bonding roller 120, allowing the bonding roller 120 to rotate more smoothly.

[0041] In some embodiments, the second frame body comprises a mounting plate 211, the compression roller 220 is rotationally connected to the mounting plate 211, and a connecting rod 240 is arranged on one side of the mounting plate 211. The first frame body 110 is provided with a through hole, and the connecting rod 240 is slidingly arranged in the through hole. One end of the elastic member 230 abuts against the mounting plate 211, and the other end abuts against the first frame body 110. It is not difficult to understand that the connecting rod 240 is arranged on the inner side of the through hole and can slide along the extension direction of the through hole. During the sliding of the connecting rod 240 in the through hole, the distance between the first frame body 110 and the mounting plate 211 also changes, and accordingly the position of the compression roller 220 rotationally arranged on the mounting plate 211 also changes. Since one end of the elastic member 230 abuts against the mounting plate 211 and the other end abuts against the first frame body 110, under the action of the elastic member 230, the mounting plate 211 will move away from the first frame body 110 until it moves to a position where the compression roller 220 contacts the laminating roller 120, thereby limiting the movement of the mounting plate 211. At this time, the compression roller 220 is also maintained in contact with the laminating roller 120 under the action of the elastic member 230.

[0042] In some embodiments, the cross section of the through hole can be circular; in other embodiments, the through hole can also be square.

[0043] In combination Figure 1 It is not difficult to understand that since the laminating roller 120 is rotationally arranged on the first frame body 110, the elastic member 230 is arranged in compression and one end abuts against the first frame body 110 and the other end abuts against the second frame body. The second frame body can make the compression roller 220 contact the laminating roller 120 under the action of the elastic member 230, so that the compression roller 220 can exert a force on the laminating roller 120 away from the first frame body 110. When the laminating roller 120 is used to roll the film on the side away from the first frame body 110, the two ends of the laminating roller 120 are rotationally arranged on the first frame body 110, so that the force applied by the user can be transmitted to the two ends of the laminating roller 120, so that the two ends of the laminating roller 120 can better contact the film; the middle position of the laminating roller 120 is subjected to the force away from the first frame body 110 from the compression roller 220, so that the middle position of the laminating roller 120 can also better contact the film, thereby enabling more areas of the film surface to be extruded by the laminating roller 120 when the laminating roller 120 rolls over the two stacked films, so as to better extrude the air between the two films, thereby reducing the air bubbles after the two films are laminated.

[0044] In some embodiments, the laminating roller 120 can be made of metal. In other embodiments, in order to reduce the requirement for flatness of the work surface during the laminating process (e.g., even if the two films are placed on a work surface with a certain curvature, the laminating roller 120 can still be used to roll the films to obtain a product with fewer air bubbles), the laminating roller 120 can be made of a flexible material, such as silicone or polyurethane. When the laminating device is used to roll the films, the laminating roller 120 can be deformed due to its flexibility and the pressure applied by the pressure roller 220. As a result, even if the work surface is not flat, the laminating roller 120 can still be adapted to the work surface, and more areas of the films can be pressed by the laminating roller 120 to squeeze out the air between the two films, thereby reducing the air bubbles between the two films. Further, the pressure roller 220 can be made of a rigid material, such as metal, to better apply the pressure from the elastic member 230 to the laminating roller 120 and deform the laminating roller 120. In other embodiments, the pressure roller 220 can also be made of other rigid materials, such as plastic.

[0045] Further, the second frame body also includes second side plates 212 connected to the two ends of the mounting plate 211, and the two second side plates 212 are located on the same side of the mounting plate 211, and the two ends of the pressure roller 220 are connected to the two second side plates 212, respectively. In some embodiments, bearings can be further arranged between the ends of the pressure roller 220 and the second side plates 212 to facilitate the rotation of the pressure roller 220.

[0046] In some embodiments, the end of the connecting rod 240 away from the mounting plate 211 is provided with a limiting portion 241, and the size of the limiting portion 241 is greater than the hole diameter of the through hole. Since the size of the limiting portion 241 is greater than the hole diameter of the through hole, the pressure assembly 200 can be hung on the first frame body 110 by the limiting portion 241, and the pressure assembly 200 is difficult to separate from the first frame body 110 during the columnar process, thereby facilitating the disassembly and assembly of the laminating device.

[0047] In other embodiments, the connecting rod 240 can not be provided with the limiting portion 241, for example, the connecting rod 240 can be a rod-shaped structure connected to the mounting plate 211 at one end, and the cross-sectional size of the rod-shaped structure does not change along the length direction of the rod-shaped structure.

[0048] Further, in some embodiments, the connecting rod 240 is threadedly connected with the mounting plate 211, and the connecting rod 240 is convenient to dismount from the mounting plate 211. For example, the connecting rod 240 can be a bolt in the prior art, and a threaded hole is provided on the mounting plate 211, and one end of the connecting rod 240 is screwed into the threaded hole of the mounting plate 211, thereby achieving the threadedly connection with the mounting plate 211. In the embodiment in which the connecting rod 240 is a bolt, the head of the bolt is the limiting portion 241 of the connecting rod 240. Further, the maximum distance between the second mounting frame and the first mounting frame can be adjusted by screwing or unscrewing the connecting rod 240, thereby changing the degree of extrusion of the pressing roller 220 on the laminating roller 120.

[0049] In some other embodiments, the connecting rod 240 can also be a threaded structure such as a threaded stud in the prior art.

[0050] Further, in some embodiments, the elastic member 230 is sleeved on the connecting rod 240. In this embodiment, the elastic member 230 is sleeved on the outside of the connecting rod 240, which can limit and guide the elastic member 230 by the connecting rod 240. And since the pressing assembly 200 is slidably connected with the first frame body 110 by the connecting rod 240 arranged in the through hole of the first frame body 110, the relative movement between the second frame body and the first frame body 110 is caused by the elastic member 230, therefore, the elastic member 230 is arranged on the outside of the connecting rod 240, so that the elastic member 230 driving the movement of the mounting plate 211 and the connecting rod 240 slidably arranged with the first frame body 110 are in substantially the same position, which can make the movement of the second mounting frame relative to the first mounting frame more smooth, thereby facilitating the pressing roller 220 to apply force to the laminating roller 120.

[0051] In other embodiments, the elastic member 230 and the connecting rod 240 can also be arranged at different positions, as long as the elastic member 230 can cause the movement of the second frame body relative to the first frame body 110, thereby achieving the application of force to the laminating roller 120 by the pressing roller 220.

[0052] Further, the elastic member 230 can be a cylindrical spring, or a structure of silicone or rubber with elasticity. Further, in the case that the elastic member 230 is a structure of rubber or silicone, the elastic member 230 is a ring structure and the connecting rod 240 is sleeved on the inside.

[0053] In some embodiments, the pressing assembly 200 includes two pressing rollers 220 arranged side by side on the mounting plate 211, and both of the pressing rollers 220 are in contact with the laminating roller 120. It is not difficult to understand that the pressing roller 220 is a columnar structure in strip shape, and the arrangement of the pressing rollers 220 side by side means that the axes of the two pressing rollers 220 are almost parallel to each other, and one end of one pressing roller 220 is almost aligned with one end of the other pressing roller 220, and the other end of one pressing roller 220 is almost aligned with the other end of the other pressing roller 220.

[0054] Since the two pressing rollers 220 are arranged side by side and both are in contact with the laminating roller 120, that is, the two pressing rollers 220 are in contact with the laminating roller 120 from two positions on the circumference of the laminating roller 120, the pressing force exerted by the pressing rollers 220 can better limit the bending direction of the laminating roller 120, and also make the deformation direction of the laminating roller 120 after being stressed more stable, thereby making the film better laminated to reduce the bubbles existing between the laminated films.

[0055] Further, in some embodiments, the mounting plate 211 is provided with four connecting rods 240, each of which is arranged on the mounting plate 211 corresponding to one end of one pressing roller 220. It is not difficult to understand that each pressing roller 220 has two ends, and the two pressing rollers 220 have four ends, and by arranging the four connecting rods 240 one by one corresponding to the ends of the pressing rollers 220, the pressing force of the elastic member 230 sleeved outside the connecting rod 240 can be better transmitted to the pressing roller 220, thereby making the pressing roller 220 better play the role of abutting against the laminating roller 120 to make the bubbles between the laminated films less.

[0056] Further, in some embodiments, a pressing assembly 200 is arranged at an interval of 200mm-500mm along the axial direction of the laminating roller 120. Specifically, the distance between two pressing assemblies 200 can be 200mm, 300mm, 400mm or 500mm. That is, in some embodiments, two or more pressing assemblies 200 are arranged along the axial direction of the laminating roller 120, the distance between two adjacent pressing assemblies 200 is 200mm-500mm, and the distance between the pressing assemblies 200 and the ends of the laminating roller 120 is also 200mm-500mm. That is, in this embodiment, the laminating roller 120 is in contact with the pressing roller 220 or the bearing arranged between the laminating roller 120 and the first frame body 110 every 200mm-500mm in the axial direction, so that the circumferential surface of the laminating roller 120 can better contact the film to be laminated when the laminating roller 120 rolls on the surface of the film, thereby reducing the bubbles existing between the laminated films.

[0057] The above descriptions are only the preferred embodiments of the present application, and are not intended to limit the present application. The present application can have various modifications and changes for those skilled in the art. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
