Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fuel cell manufacturing, and in particular to a frame bonding device and a five-in-one forming equipment. BACKGROUND

[0002] In the production process of fuel cells, a frame needs to be bonded on both sides of a CCM (catalyst coated membrane) to obtain a five-in-one assembly. The bonding method of the CCM and the frame generally includes sheet-to-sheet bonding and discontinuous roll-to-roll bonding.

[0003] In the sheet-to-sheet bonding method, the CCM and the frame are both sheet materials, and the semi-finished product after the CCM is aligned and bonded with the first frame is bonded with another frame. In the discontinuous roll-to-roll bonding method, the frame material is a roll material, and the CCM material can also be a roll material. At this time, a single CCM with a skip distance is obtained by first performing a semi-discontinuous cutting on the equipment, and then the waste at the skip distance is removed. Then, the single CCM is bonded with two layers of frames in turn.

[0004] In the process of sheet-to-sheet bonding, the CCM and the frame of each sheet material need to be positioned and aligned. In the discontinuous roll-to-roll bonding method, the bonding action can only be performed when the material belt does not move. Therefore, the existing bonding method can result in low production efficiency of fuel cells. SUMMARY

[0005] Therefore, it is necessary to provide a frame bonding device that can improve the production efficiency of fuel cells.

[0006] A frame bonding device comprises:

[0007] a CCM feeding mechanism for continuously cutting a CCM material belt fed at a first speed into CCM sheet materials;

[0008] a bonding roller around which the frame material belt can pass; and

[0009] a return mechanism comprising a circulation track and a plurality of carriers capable of moving along the circulation track, the plurality of carriers being capable of moving to a material receiving position in turn and receiving the CCM sheet materials output by the CCM feeding mechanism, and moving to a bonding position to bond the received CCM sheet materials with the frame material belt passing around the bonding roller;

[0010] wherein the moving speed of each carrier is adjustable, and each carrier is capable of passing through the material receiving position at the first speed and accelerating to a second speed consistent with the linear speed of the bonding roller to pass through the bonding position.

[0011] In one of the embodiments, there is no gap between two adjacent CCM sheet materials cut from the CCM material tape by the CCM feeding mechanism, and the two adjacent carrier plates abut at the receiving position, and the two adjacent carrier plates are spaced apart during the transfer to the laminating position.

[0012] In one of the embodiments, the CCM feeding mechanism comprises:

[0013] a CCM unwinding shaft for unwinding the CCM material tape;

[0014] a roll cutting assembly capable of roll cutting the CCM material tape unwound from the CCM unwinding shaft to obtain a plurality of CCM sheet materials.

[0015] In one of the embodiments, the roll cutting assembly comprises a bottom roller and a knife roller, and the CCM material tape can pass between the bottom roller and the knife roller and be cut into the CCM sheet materials by the knife roller.

[0016] In one of the embodiments, the CCM feeding mechanism further comprises:

[0017] a backing film unwinding shaft for unwinding a backing film material tape;

[0018] a composite roller located upstream of the roll cutting assembly, the composite roller being capable of receiving the backing film material tape and the CCM material tape and compositing a first composite material tape, and the roll cutting assembly being capable of cutting the first composite material tape and cutting off the CCM material tape to obtain a plurality of CCM sheet materials arranged along the extension direction of the backing film material tape;

[0019] a peeling knife, the first composite material tape output by the cutting assembly can pass around the peeling knife under the action of a pulling force, so that the CCM sheet materials are sequentially peeled off from the backing film material tape and received by the carrier plates.

[0020] In one of the embodiments, the peeling knife comprises a first guide surface and a second guide surface, the first guide surface and the second guide surface form an acute angle therebetween, and the first composite material tape can pass through the first guide surface and the second guide surface in sequence.

[0021] In one of the embodiments, the CCM feeding mechanism further comprises a waste material winding shaft for winding the first composite material tape passing through the peeling knife.

[0022] In one of the embodiments, the laminating roller is a heating roller.

[0023] In one of the embodiments, the carrier plate has a carrying surface capable of adsorbing the CCM sheet materials.

[0024] The frame fitting device can transfer the CCM sheet material to the fitting station and fit with the frame material belt after the CCM sheet material is received by the receiving position of the carrier plate. The carrier plate can be adjusted to the first speed at the receiving position, so as to smoothly receive the CCM sheet material. Then, the carrier plate carrying the CCM sheet material is accelerated to the second speed to realize synchronization with the fitting roller. At the same time, the required interval between the adjacent two CCM sheet materials can be generated. The multiple carrier plates continuously circulate along the circulating track, and the CCM sheet material output by the CCM feeding mechanism can be continuously transferred to the fitting position. In this way, the frame material belt and the CCM material belt can realize continuous belt running during the fitting process, so as to significantly improve the production efficiency of the fuel cell.

[0041] Referring to Figures 1 to 8 , the present application provides a five-in-one forming equipment and a frame fitting device 10. The five-in-one forming equipment comprises the frame fitting device 10. The frame fitting device 10 comprises a CCM feeding mechanism 100, a fitting roller 200 and a reflow mechanism 300.

[0042] The CCM feeding mechanism 100 can continuously cut the CCM tape 20 into CCM sheet materials 21; the frame tape 30 to be fitted can be wound around the fitting roller 200; the reflow mechanism 300 comprises a circulating track 310 and a plurality of carrier plates 320. The plurality of carrier plates 320 can move along the circulating track 310, so as to sequentially transfer the CCM sheet materials 21 output by the CCM feeding mechanism 100 to the fitting roller 200, and make the CCM sheet materials 21 fit with the frame tape 30.

[0043] As Figure 8 shown, the CCM sheet materials 21 and the frame tape 30 can be fitted to obtain a second composite tape 60. The frame tape 30 can be an upper frame or a lower frame. The side of the frame tape 30 away from the CCM sheet materials 21 is also attached with a protective film tape 31. The five-in-one forming equipment can further process the second composite tape 60, for example, fitting another frame on the side of the second composite tape 60 to which the CCM sheet materials 21 are attached.

[0044] The CCM material tape 20 can be fed at a first speed, and the laminating roller 200 drives the frame material tape 30 on it to rotate at a second speed. The first speed and the second speed are both linear speeds, and the first speed is less than the second speed. Moreover, the CCM feeding mechanism 100 can continuously cut the CCM material tape 20. Continuous cutting means that the CCM material tape 20 does not need to stop feeding during the cutting process, so that the CCM material tape 20 can be continuously fed.

[0045] Please refer to Figure 1 In this embodiment, the CCM feeding mechanism 100 includes a CCM unwinding shaft 110 and a roller cutting assembly 120. The CCM unwinding shaft 110 is used to unwind the CCM material tape 20, and the roller cutting assembly 120 can roll cut the CCM material tape 20 unwound by the CCM unwinding shaft 110 to obtain a plurality of CCM sheet materials 21. The CCM unwinding shaft 110 can continuously unwind the CCM material tape 20, and the roller cutting assembly 120 can continuously cut the CCM material tape 20 by roll cutting.

[0046] It should be pointed out that in other embodiments, the CCM feeding mechanism 100 can also use follow-up die cutting and the like to continuously cut the CCM material tape 20.

[0047] In this embodiment, the roller cutting assembly 120 includes a bottom roller 121 and a knife roller 122, and the CCM material tape 20 can pass between the bottom roller 121 and the knife roller 122 and be cut into CCM sheet materials 21 by the knife roller 122.

[0048] The knife roller 122 and the bottom roller 121 generally rotate under the drive of independent driving members such as servo motors, and the linear speeds of the knife roller 122 and the bottom roller 121 are the same. The knife roller 122 and the bottom roller 121 have a gap for the CCM material tape 20 to pass through, and the bottom roller 121 serves as a bearing to support the CCM material tape 20 during cutting by the knife roller 122.

[0049] Please refer to Figure 3 The outer surface of the knife roller 122 is provided with a knife line 1221, and the knife line 1221 surrounds a cutting pattern 1222 on the outer surface of the knife roller 110. Specifically, the CCM material tape 20 passes through the gap between the knife roller 122 and the bottom roller 121, and the CCM material tape 20 is extruded by the knife line 1221 and is cut into a plurality of CCM sheet materials 21 in sequence, and the CCM sheet materials 21 match the cutting pattern 1222 on the surface of the knife roller 122. The outer surface of the knife roller 122 in this embodiment forms two cutting patterns 1222, so that the knife roller 122 cuts two CCM sheet materials 21 per revolution.

[0050] Further, in the present embodiment, the CCM feeding mechanism 100 further comprises a backing film unwinding shaft 130, a laminating roller 140 and a stripping knife 150.

[0051] The backing film unwinding shaft 130 is used to unwind the backing film web 40. The backing film web 40 can be a PET film, which has good toughness. The laminating roller 140 is located upstream of the roll cutting assembly 120. The laminating roller 140 can receive the backing film web 40 and the CCM web 20 and laminate them to obtain the first laminated web 50. The CCM web 20 enters the roll cutting assembly 120 only after being laminated with the backing film web 40. The laminating roller 140 can be driven by a separate driving member and can laminate the backing film web 40 and the CCM web 20 by means of roller pressing. The roll cutting assembly 120 cuts the first laminated web 50, cutting the CCM web 20 but not cutting the backing film web 40, to obtain a plurality of CCM sheet materials 21 arranged along the extension direction of the backing film web 40.

[0052] The backing film web 40 can provide support and protection for the CCM web 20 and can act as a substrate for the CCM web 20 during the roll cutting process of the CCM sheet materials 21. Moreover, the plurality of CCM sheet materials 21 obtained by cutting can still be attached to the backing film web 40 and be transported with the backing film web 40 as a support carrier, thereby avoiding the scattering or positional deviation of the CCM sheet materials 21 obtained by cutting.

[0053] The first laminated web 50 output by the cutting assembly can be wound around the stripping knife 150 under the action of a pulling force, so that the CCM sheet materials 21 are sequentially stripped from the backing film web 40. When the first laminated web 50 is wound around the stripping knife 150, the running direction of the first laminated web 50 will change. Since the CCM sheet materials 21 have a certain rigidity, the CCM sheet materials 21 will continue to be transported along the original running direction, resulting in an action force between the CCM sheet materials 21 and the backing film web 40 that forces them to move away from each other. When the adhesion of the backing film web 40 is not sufficient to resist the action force, the CCM sheet materials 21 will separate from the backing film web 40, thereby forming a stripping angle. After the CCM sheet materials 21 are stripped, they can continue to move along the original running direction and be received by the carrier plate 320. The stripping knife 150 can strip the CCM sheet materials 21 from the backing film web 40 by taking advantage of the difference in material properties, and the stripping process does not require contact with the CCM sheet materials 21, thereby avoiding damage to the CCM sheet materials 21.

[0054] As Figure 7 and Figure 8As shown, the CCM tape 20 is attached with a supporting film tape 22 on one side, which is used to protect the surface of the CCM tape 20 during storage and unwinding. When the roll cutting assembly 122 cuts, the supporting film tape 22 is cut together with the CCM tape 20, and a supporting film piece tape 23 is obtained. When the first composite film 50 is wound through the peeling knife 150, the supporting film piece tape 23 is separated from the backing film tape 40 together with the CCM piece tape 21.

[0055] Specifically, in the embodiment, the peeling knife 150 includes a first guide surface (not marked in the figure) and a second guide surface (not marked in the figure), and the first guide surface and the second guide surface form an acute angle therebetween, and the first composite tape 50 can pass through the first guide surface and the second guide surface in sequence. The peeling knife 150 has a wedge-shaped block structure, and when the first composite tape 50 is wound through the peeling knife 150, a peeling acute angle is formed at the joint of the first guide surface and the second guide surface, so that the CCM piece tape 21 can be smoothly peeled off.

[0056] Please refer to Figure 1 In the embodiment, the CCM feeding mechanism 100 further includes a waste winding shaft 160, which is used to wind the first composite tape 50 that has passed through the peeling knife 150. On the one hand, the waste winding shaft 160 can provide a traction force to the first composite tape 50, so that the first composite tape 50 can pass through the peeling knife 150; on the other hand, the waste winding shaft 160 can also wind the waste generated by cutting the backing film tape 40 and the CCM tape 20, so as to avoid scattering.

[0057] The laminating roller 200 is generally also driven by an independent driving member, such as a servo motor. The frame tape 30 to be laminated is generally pre-coated with hot melt adhesive during preparation, so the laminating roller 200 is generally a heating roller. Therefore, when the frame tape 30 passes through the laminating roller 200, the laminating roller 200 can activate the hot melt adhesive on the frame tape 20 by heating, so as to facilitate the lamination with the CCM piece tape 21. Of course, if the initial adhesion of the frame tape 30 is relatively high, the laminating roller 200 can also adopt a common compression roller.

[0058] As shown in Figure 5 and Figure 6 As shown, the frame tape 30 is formed with a plurality of inner frames 301 in the extension direction in sequence, and the material in the region of the inner frame 301 is hollowed out. When laminating, a plurality of CCM piece tapes 21 need to be aligned and laminated with the regions corresponding to the plurality of inner frames 301 in sequence.

[0059] Please refer to Figure 2The circulating track 310 can be spliced by a plurality of guide rails, and the plurality of carrier plates 320 can move along the circulating track 310 to move between the receiving position and the bonding position. Specifically, the circulating track 310 includes an upper fixed spliced guide rail, a lower fixed spliced guide rail, a left side moving spliced guide rail, a right side moving spliced guide rail, a left side fixed guide rail, and a right side fixed guide rail. The left side moving spliced guide rail and the right side moving spliced guide rail can move up and down on the left side fixed guide rail and the right side fixed guide rail, respectively, so as to transfer the carrier plate 320 between the upper fixed spliced guide rail and the lower fixed spliced guide rail.

[0060] The plurality of carrier plates 320 can circulate counterclockwise or clockwise. At the receiving position, the plurality of carrier plates 320 can sequentially receive the CCM sheet material 21 output by the CCM feeding mechanism 100; the carrier plate 320 carrying the CCM sheet material 21 moves to the bonding position, and the carrier plate 320 can bond the received CCM sheet material 21 to the frame strip 30 around the bonding roller 200.

[0061] In order to avoid the carrier plate 320 from causing the CCM sheet material 21 to fall off or displace during the transfer of the CCM sheet material 21, specifically in the embodiment, the carrying surface of the carrier plate 320 can adsorb the CCM sheet material 21. The carrier plate 320 can adsorb the CCM sheet material 21 by electrostatic adsorption or negative pressure adsorption, so as to avoid the CCM sheet material 21 from being displaced relative to the carrier plate 320 during the transfer.

[0062] Further, each carrier plate 320 includes an independent power assembly. Specifically, the power assembly can be a mover of a linear motor, and a structure similar to a stator of a linear motor is arranged on the circulating track 310, so that each carrier plate 320 has independent power. Therefore, the moving speed of each carrier plate 320 can be adjusted individually. Moreover, each carrier plate 320 can pass through the receiving position at a first speed and can accelerate to a second speed to pass through the bonding position. As described above, the second speed is consistent with the linear speed of the bonding roller 200, and the second speed is greater than the first speed.

[0063] When the frame bonding device 10 starts to work, the carrier plate 320 moves at the first speed at the receiving position, and the CCM sheet material 21 output by the CCM feeding mechanism 100 remains relatively stationary, so as to facilitate receiving the CCM sheet material 21; then, the carrier plate 320 carrying the CCM sheet material 21 leaves the receiving position and accelerates to the second speed. In this way, when the carrier plate 320 reaches the bonding position, the carried CCM sheet material 21 can be bonded synchronously with the frame strip 20 on the bonding roller 200.

[0064] Meanwhile, the acceleration of the carrier plate 320 can also increase the distance between the carrier plate 320 and the next carrier plate 320. Therefore, the required interval between the two adjacent CCM sheet materials 21 entering the bonding position can be generated, so that the plurality of CCM sheet materials 21 can be aligned with the plurality of inner frames 301 on the frame tape 30 one by one.

[0065] The frame bonding device 10 needs to be debugged in the initial state. When the carrier plate 320 carrying the CCM sheet material 21 reaches the bonding position, a bonding area (an area corresponding to one inner frame 301) on the frame tape 30 is just moved to the bonding starting point (the lowest point of the bonding roller 200) of the bonding roller 200. Moreover, when the next carrier plate 320 carrying the CCM sheet material 21 reaches the bonding position, the next bonding area is also just moved to the bonding starting point of the bonding roller 200.

[0066] Please refer to Figure 4 In the embodiment, there is no skip distance between the two adjacent CCM sheet materials 21 obtained by cutting the CCM tape 20 by the CCM feeding mechanism 100. The two adjacent carrier plates 320 located at the receiving position abut each other, and the interval between the two adjacent carrier plates 320 is generated during the movement to the bonding position.

[0067] Specifically, the surfaces of the two adjacent cutting patterns 1222 of the cutter roller 122 abut each other, and are only separated by a cutter line 1221. Therefore, there is no skip distance between the two adjacent CCM sheet materials 21 obtained by cutting, that is, the two adjacent CCM sheet materials 21 are just cut off without generating waste materials. In this way, the waste of materials can be significantly reduced, thereby reducing the cost. In addition, the edges of the CCM tape 20 after cutting will generate waste materials, which can be wound together with the bottom film tape 40 by the waste material winding shaft 160.

[0068] Since the two adjacent carrier plates 320 abut each other, when the previous carrier plate 320 completes the receiving of the CCM sheet material 21 and leaves the receiving position, the next carrier plate 320 can immediately enter the receiving position and receive the next CCM sheet material 21. In this way, when the CCM tape 20 continuously runs and continuously outputs the CCM sheet materials 21, the CCM sheet materials 21 can be timely transferred.

[0069] After the previous carrier plate 320 carries the CCM sheet material 21, it accelerates to move to the bonding position, while the next carrier plate 320 still needs to move at the first speed in the receiving position to smoothly carry the CCM sheet material 21. In this way, during the movement to the bonding position, an interval is generated between the two adjacent carrier plates 320.

[0070] The frame fitting device 10 can transfer the CCM sheet 21 to the fitting station and fit the CCM sheet 21 with the frame strip 30 after the carrier plate 320 receives the CCM sheet 21 at the receiving position. The carrier plate 320 can be adjusted to the first speed at the receiving position, so as to smoothly receive the CCM sheet 21. Then, the carrier plate 320 carrying the CCM sheet 21 accelerates to the second speed to synchronize with the fitting roller 200. Meanwhile, the required interval between the adjacent two CCM sheets 21 can be generated. The plurality of carrier plates 320 continuously circulate along the circulating track 310, so as to continuously transfer the CCM sheet 21 output by the CCM feeding mechanism 100 to the fitting position. In this way, the frame strip 30 and the CCM strip 20 can realize continuous running during the fitting process, so as to significantly improve the production efficiency of the fuel cell.

[0071] The technical features of the above-described embodiments can be combined in any manner. In order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not contradict, they should be considered as falling within the scope of the present disclosure.

[0072] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the patent. It should be pointed out that for those skilled in the art, some modifications and improvements can be made without departing from the concept of the present application, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
