Laminating equipment and laminating method

Abstract

The present application relates to a laminating device for laminating the ccm on a base film with the first area on a second material belt, and the laminating device includes a first conveying mechanism, a second conveying mechanism and a laminating mechanism. The second conveying mechanism first bends the second area of ​​the second material belt to form a fixed section. Since the second area in the fixed section is bent, the distance between the two frames adjacent to the bent second area is shortened, so that the multiple frames in the fixed section can correspond one to one with the multiple ccm on the base film. Then, it is only necessary to convey the base film and the fixed section to the laminating station at the same speed, and the ccm can be laminated to the frame through the laminating mechanism. Since the distance between the two adjacent frames is pre-adjusted, the base film and the fixed section can be conveyed at the same speed during laminating, which effectively improves the laminating efficiency. The present application also relates to a laminating method.

Description

Technical Field

[0001] The present application relates to the technical field of fuel cell preparation, and in particular to a bonding device and a bonding method. Background Art

[0002] During fuel cell fabrication, the catalyst-coated membrane (CCM), coated with anode and cathode catalysts, must be precisely bonded to the square, hollowed-out area in the center of the frame. To maintain tension and prevent air bubbles during bonding, roll-to-roll bonding is employed: the base membrane carrying the CCM sheet is bonded to the tape carrying the frame.

[0003] However, the spacing between the ccm sheets on the base film is much smaller than the spacing between the upper frames of the material strip, resulting in the base film and the material strip needing to be fed separately during the roll-to-roll lamination process, and the base film needs to be fed intermittently and aligned in a fixed position before lamination, resulting in low lamination efficiency. Summary of the Invention

[0004] Based on this, it is necessary to provide a high-efficiency laminating device and laminating method for laminating ccm sheets and frames through roll-to-roll to address the problem of low efficiency of existing ccm sheets and frames laminating through roll-to-roll.

Then, it is only necessary to convey the base film and the fixed segment to the laminating station at the same speed, and the ccms are laminated to the frames by the laminating mechanism.

[0040] like Figure 1 As shown, a bonding device 100 is provided in one embodiment of the present application, and the bonding device 100 is used to bond the sheet material 300 on the first material tape 200 with the first area 401 on the second material tape 400. A plurality of sheets 300 are arranged at intervals on the first material tape 200, and the second material tape 400 has a plurality of first areas 401 and a plurality of second areas arranged alternately in sequence.

[0041] It should be noted that, in this embodiment, the first material strip 200 is the base film, the sheet material 300 is ccm, the second material strip 400 is the material strip carrying the frame, and the first area 401 is the area where the frame is located. The laminating equipment is used to laminate the ccm on the frame, and the laminating is performed in a roll-to-roll manner.

[0042] In some embodiments, the bonding apparatus 100 includes a first conveying mechanism 10 , a second conveying mechanism 20 , and a bonding mechanism 30 .

[0043] The first conveying mechanism 10 is used to convey the first material belt 200 along a first path and at a first conveying speed, so that the sheets 300 on the first material belt 200 pass through the bonding stations in sequence.

[0044] The second conveying mechanism 20 is used to bend the second area of ​​the second material belt 400 to form a fixed section having multiple first areas 401 and multiple curved second areas. The second conveying mechanism 20 is also used to convey the fixed section along a second path and at a second conveying speed so that the multiple first areas 401 in the fixed section pass through the bonding station in sequence, and the first areas 401 conveyed to the bonding station are aligned with the sheet material 300 conveyed to the bonding station.

[0045] The laminating mechanism 30 is used to laminate the sheet material 300 conveyed to the laminating station to the first area 401 conveyed to the laminating station.

[0046] The first conveying speed and the second conveying speed are of the same magnitude.

[0047] By setting up the above-mentioned laminating equipment, the second conveying mechanism 20 first bends the second area of ​​the second material belt 400 to form a fixed section. Since the second area in the fixed section is bent, the distance between the two frames adjacent to the bent second area is shortened, so that the multiple frames in the fixed section can correspond one-to-one with the multiple ccms on the base film. Then, it is only necessary to convey the base film and the fixed section to the laminating station at the same speed, and the ccms are laminated to the frames by the laminating mechanism 30. Since the distance between the two adjacent frames is pre-adjusted, the base film and the fixed section can be conveyed at the same speed during lamination, without the need for separate feeding and the base film does not need to be loaded intermittently, which effectively improves the lamination efficiency.

[0048] It should be noted that the distance between two adjacent frames refers to the distance between two adjacent frames on the second path, rather than the distance between two adjacent frames on the second material strip 400 .

[0049] At the same time, since the size of the frame will be larger than the size of the ccm, the curved second area adjusts the distance between the two adjacent frames, and will be adjusted according to the distance between the two adjacent ccms and the size of the frame and the ccm, so that when the base film and the fixed section are transported at the same conveying speed, the ccm transported to the bonding station can be aligned with the frame transported to the bonding station.

[0050] It can be understood that the fixed section includes multiple first areas 401 and multiple curved second areas, and the multiple first areas 401 and the multiple curved second areas are arranged alternately. In the process of conveying the fixed section along the second path, the multiple first areas 401 in the fixed section can pass through the bonding station in sequence. Therefore, it can be concluded that the second conveying mechanism 20 bends the second area adjacent to the first area 401 before conveying it to the bonding station. Bending the second area in advance can adjust the distance between the two adjacent first areas 401 in advance. Subsequently, it is only necessary to convey the fixed section at the second conveying speed, without the need for intermittent conveying to adjust the distance, which further ensures the bonding efficiency.

[0051] In some embodiments, the bonding device also includes a first detection component 40 and a second detection component 50. The first detection component 40 is used to detect the distance between two adjacent sheets 300 on the first material belt 200, and the second detection component 50 is used to detect the position of the first area 401 on the second material belt 400. The second conveying mechanism 20 is used to bend the second area according to the detection results of the first detection component 40 and the second detection component 50.

[0052] In other words, the second conveying mechanism 20 adjusts the distance between two adjacent first areas 401 according to the detection results of the first detection component 40 and the second detection component 50, so that when the first material belt 200 and the fixed section are conveyed at the same speed, each sheet 300 conveyed to the bonding station can be aligned with a first area 401 conveyed to the bonding station.

[0053] It should be noted that when there is a slight deviation in the spacing between the sheets 300, that is, when multiple sheets 300 are not evenly spaced on the first material belt 200, the degree of curvature of the second area can be adjusted according to the detection results of the first detection component 40 and the second detection component 50 to adjust the spacing between two adjacent first areas 401, ensuring that each sheet 300 transported to the bonding station can be aligned with a first area 401 transported to the bonding station, and at the same time, the bonding efficiency is still guaranteed when there is a slight gap in the spacing between the sheets 300.

[0054] In some embodiments, the first conveying mechanism 10 includes a plurality of rollers 11 arranged in sequence along the first path, and the first material belt 200 is sequentially wound around the plurality of rollers 11, so that the first material belt 200 is conveyed along the first path.

[0055] In some embodiments, the second conveying mechanism 20 includes multiple groups of support components 21 and multiple groups of adjustment components. Each support component 21 is connected to a corresponding adjustment component, and each support component 21 can move along the second path, so each adjustment component can move along the second path with the support component 21.

[0056] During the movement of multiple groups of support components 21 and multiple groups of adjustment components along the second path, the multiple groups of support components 21 are arranged at intervals along the moving direction, each support component 21 is used to support the first area 401 of the second material strip 400, and each adjustment component at least partially extends between two adjacent groups of support components 21 to bend the second area of ​​the second material strip 400 between the two adjacent groups of support components 21.

[0057] It can be understood that by using multiple groups of support components 21 and multiple groups of adjustment components, the second area can be bent in advance to ensure the fitting efficiency.

[0058] In some embodiments, the second conveying mechanism 20 also includes a conveying drive member, which is simultaneously connected to multiple groups of support components 21 for driving the multiple groups of support components 21 to move cyclically along a closed path. The closed path includes a return path and the above-mentioned second path. The second path is connected to the return path end to end to achieve a closed loop.

[0059] It should be noted that the conveying drive member can be connected to multiple groups of support assemblies 21, and each adjustment assembly can be connected to a corresponding support assembly 21, thereby achieving synchronous movement of the adjustment assembly and the support assembly 21. In another embodiment, the conveying drive member can also be in transmission connection with multiple groups of support assemblies 21 and multiple groups of adjustment assemblies at the same time to drive the multiple groups of support assemblies 21 and multiple groups of adjustment assemblies to move synchronously along a closed path.

[0060] Assume that the plurality of support components 21 include first support components and second support components sequentially arranged along the moving direction on a closed path.

[0061] When the first support component moves to the starting point of the second path, the second support component is already located in the second path. Both the first support component and the second support component can support the second material strip 400. The adjustment component extending between the first support component and the second support component can bend the second area.

[0062] When the first supporting assembly moves to the end point of the second path, the first supporting assembly may support the first region 401 of the second material strip 400 , and the second supporting assembly is separated from the second material strip 400 .

[0063] Combine Figure 1 To explain, Figure 1 Among them, a1 is the support assembly 21 located at the starting point of the second path, a2 is the support assembly 21 located at the laminating station, and a3 is the support assembly 21 located at the end point of the second path.

[0064] when Figure 1 When a1 is the first supporting component, a2 is the second supporting component, and both the first supporting component and the second supporting component support the second material strip 400. At this time, the second supporting component is located at the bonding station, that is, the position of the first area 401 supported by the second supporting component has been adjusted, and the adjusting component located between the first supporting component and the second supporting component can bend the second area of ​​the second material strip 400 to adjust the position of the first area 401 on the first supporting component.

[0065] when Figure 1 When a3 is the first supporting component, a4 is the second supporting component. At this time, the first supporting component can support the first area 401 of the second material strip 400, while the second supporting component is separated from the second material strip 400.

[0066] It is understandable that Figure 1 In the illustrated embodiment, the closed path is a circular path. After the second supporting assembly is separated from the second material strip 400 , the second supporting assembly continues to move along the closed path until it reaches the starting point of the second path, and can then re-support the second material strip 400 .

[0067] In some embodiments, when the closed path is a circular path, the second conveying mechanism 20 also includes a connecting shaft 22, and the conveying drive member is transmission-connected to the connecting shaft 22 to drive the connecting shaft 22 to rotate, and multiple groups of support components 21 are arranged on the side of the connecting shaft 22 at intervals along the circumference of the connecting shaft 22, and each adjustment component at least partially extends between two adjacent groups of adjustment components.

[0068] In some embodiments, the support assembly 21 includes a first support roller 211, a support block 212 and a second support roller 213. The first support roller 211 and the second support roller 213 are rotatably disposed on the support block 212, and in the process of the support assembly 21 moving along the second path, the first support roller 211, the support block 212 and the second support roller 213 are arranged in sequence along the second path, and the second material belt 400 is wound around the first support roller 211, the support block 212 and the second support roller 213.

[0069] Combine Figure 1 and Figure 2 It can be understood that by arranging the first support roller 211 and the second support roller 213 on both sides of the support block 212, the second material tape 400 is wound around the first support roller 211, the support block 212 and the second support roller 213, so that the second material tape 400 will not contact the edge of the support block 212, thereby avoiding scratching the second material tape 400.

[0070] Combined with Figure 1 It should be noted that in Figure 1 In the illustrated embodiment, the support blocks 212 in the multiple support assemblies 21 are integrally arranged with the connecting shaft 22, and an adjustment groove 23 is formed between two adjacent support blocks 212. At least part of the adjustment assembly can extend into the adjustment groove 23 to bend the second area of ​​the second material strip 400.

[0071] In practice, the support block 212 has a support surface, and the second web 400 is wound around the first support roller 211, the support surface, and the second support roller 213. The support surface is used to support the first region 401. Therefore, it can be seen that the adjustment assembly is used to adjust the position of the first region 401 on the support surface so that the first region 401 is aligned with the web 300 when the support surface moves to the lamination station.

[0072] In some embodiments, the adjustment component includes an adjustment roller 24, which can move back and forth along the first direction and the second direction, and can rotate around a rotation axis parallel to the first direction. During the movement of the adjustment roller 24, there is an avoidance position and a position to be pressed.

[0073] When the adjusting roller 24 is in the avoidance position, the adjusting roller 24 and the second material belt 400 are staggered in the second direction; when the adjusting roller 24 is in the position to be pressed, the adjusting roller 24 and the second material belt 400 correspond to each other in the second direction, so that the second material belt 400 is pressed between the two adjacent groups of support components 21 during the movement of the adjusting roller 24 along the second direction.

[0074] The first direction and the second direction are perpendicular to each other, and the second direction is perpendicular to the second path. Figure 1 In the figure, the first direction is the X direction, that is, the axial direction of the connecting shaft 22, and the second direction is the radial direction of the connecting shaft 22.

[0075] Combine Figure 1 To explain, Figure 1 Here, a1 is the support assembly 21 at the starting point of the second path, a5 is the support assembly 21 adjacent to a1 and about to enter the second path, and b is the adjustment roller 24 located on the side of a1 away from a2. b1 and b2 are different positions of the adjustment roller b. b1 is the position to be pressed in, and b2 is the position after the adjustment roller b presses the second material strip 400 into the adjustment groove 23. a3 is the support assembly 21 at the end of the second path, a4 is the support assembly 21 located outside the second path, and c is the adjustment roller 24 located between a3 and a4. c1, c2, c3, and c4 are different positions of the adjustment roller c. c1 is the position when bending the second region, c2 is the position of the adjustment roller c after moving out of the adjustment groove 23 along the second direction, and c3 and c4 can be two different avoidance positions.

[0076] When the support assembly 21 moves to the position of a1, the second material strip 400 will cover the opening of the adjustment groove 23 between a1 and a5 under the action of gravity, and the adjustment roller b will first move from the position of b2 along the first direction to the avoidance position, and then move to the position of b1. Next, the adjustment roller b moves toward the second material strip 400 along the second direction to press the second material strip 400 into the adjustment groove 23, thereby bending the second area of ​​the second material strip 400.

[0077] When the support assembly 21 moves to the position a3, the adjusting roller c moves from the position c1 to the position c2, so that the second material belt 400 moves out of the adjustment groove 23 under the action of gravity. Next, the adjusting roller c moves to the position c3 to avoid the second material belt 400 and prevent the adjusting roller c from contacting the second material belt 400 during the rotation of the connecting shaft 22 and the support assembly 21. The adjusting roller 24 can then move to the position c4 first, and then move to the position c1 to return to the adjustment groove 23.

[0078] Combine Figure 2 It should be noted that, assuming Figure 2In the figure, d1 is the support assembly 21 located at the starting point of the second path, d2 is the support assembly 21 adjacent to d1 and located on the second path, and e is the adjustment roller 24 located between d1 and d2.

[0079] When the support assembly 21 moves to the position of d1, the second material belt 400 covers the adjustment groove 23 between d1 and d2, and then the adjustment roller e can be first translated to the avoidance position, and then the adjustment roller e can be raised and translated to the position to be pressed in. Next, the adjustment roller e moves toward the second material belt 400 below, and the second material belt 400 can be pressed into the adjustment groove 23 between d1 and d2 to realize the bending of the second area, while making d1 and d2 support the first area 401.

[0080] Combine Figure 1 It can be understood that in order to avoid the adjustment component being restricted by the tension of the second material belt 400 when bending the second area, or to avoid the fluctuation of the feeding speed of the second material belt 400 when the adjustment component releases the second material belt 400 bent in the adjustment groove 23, the second material belt 400 on the upstream and downstream sides of the bonding equipment can be set to be tension-free, that is, floating between the bonding equipment and the upstream and downstream equipment, or a buffer mechanism can be set on the upstream and downstream sides of the bonding equipment to buffer the second material belt 400, which is not restricted here.

[0081] It can also be understood that when a tension-free setting is adopted, the tension of the second material strip 400 during the bonding process is provided by the friction between the second material strip 400 and the adjustment roller 24, the first support roller 211, the support surface and the second support roller 213.

[0082] In addition, it should be noted that Figure 1 In the embodiment shown, the first detection component 40 can detect the distance between adjacent sheets 300 in advance, and the second detection component 50 can detect the position of the first area 401 on the support surface in advance. Therefore, the position of the first area 401 can be adjusted in advance according to the detection results of the first detection component 40 and the second detection component 50 to ensure the fitting speed.

[0083] In some embodiments, the adjustment assembly further includes a first driving member, a second driving member and a mounting block. The first driving member is connected to the support assembly 21 and is transmission-connected to the second driving member to drive the second driving member to move back and forth in the first direction. The second driving member is transmission-connected to the mounting block to drive the mounting block to move back and forth in the second direction. The adjustment roller 24 is arranged on the mounting block.

[0084] In order to facilitate understanding of the technical solution of this application, Figure 1 The working process of the bonding device in the above embodiment is described, and the following description takes the moving direction of the support component 21 as the positive direction:

[0085] The conveying drive member drives the support assembly 21 to rotate through the connecting shaft 22. When the support assembly 21 rotates to the starting point of the second path, the second material belt 400 covers the support assembly 21 and the adjustment groove 23 located behind the support assembly 21 under the action of gravity. Then, the adjustment roller 24 in the adjustment groove 23 moves to the position to be pressed under the action of the first drive member and the second drive member. Next, the second drive member drives the adjustment roller 24 to move toward the second material belt 400 to press the second material belt 400 into the adjustment groove 23 to achieve bending of the second area of ​​the second material belt 400.

[0086] When the supporting assembly 21 rotates to the laminating station, the first area 401 on the supporting surface is aligned with the sheet material 300 at the laminating station, and then the sheet material 300 is laminated to the first area 401 under the action of the laminating mechanism 30 .

[0087] After the bonding is completed, the first material belt 200 is separated from the sheet material 300 and unloaded, and the support component 21 continues to rotate. When the support component 21 rotates to the end point of the second path, the previous support component 21 of the support component 21 has been separated from the second material belt 400, and the adjustment roller 24 between the two support components 21 can first be moved out of the adjustment groove 23 along the second direction, and then moved to the avoidance position, so that the second material belt 400 is moved out of the adjustment groove 23, and finally the adjustment roller 24 is moved back into the adjustment groove 23.

[0088] See also Figure 3 , the present application also relates to a bonding method, which comprises the steps of:

[0089] S110 , conveying the first material belt 200 along a first path at a first conveying speed, so that the sheets 300 on the first material belt 200 pass through the laminating stations in sequence.

[0090] S120 , bending the second region of the second material strip 400 to form a fixed segment having a plurality of first regions 401 and a plurality of bent second regions.

[0091] S130, conveying the fixed section along the second path at a second conveying speed, the first area 401 in the fixed section can pass through the bonding station in sequence, and the first conveying speed is the same as the second conveying speed, so that the sheet 300 conveyed to the bonding station is aligned with the first area 401 conveyed to the bonding station.

[0092] S140 , laminating the sheet material 300 conveyed to the laminating station to the first area 401 conveyed to the laminating station.

[0093] By setting up the above-mentioned laminating equipment, the second area of ​​the second material strip 400 is first bent to form a fixed section. Due to the bending of the second area in the fixed section, the distance between the two adjacent frames of the bent second area is shortened, so that the multiple frames in the fixed section can correspond one-to-one with the multiple ccms on the base film. Next, it is only necessary to transport the base film and the fixed section to the laminating station at the same speed and laminarize the ccms to the frames. Because the distance between the two adjacent frames is pre-adjusted, the base film and the fixed section can be transported at the same speed during lamination, eliminating the need for separate feeding and the need for interrupted loading of the base film, effectively improving lamination efficiency.
