And then, sequentially laminating the single CCM and the two layers of frames.
During the sheet-to-sheet bonding process, the CCMs and the frame of each sheet material need to be positioned and aligned. In the discontinuous roll-to-roll bonding method, the bonding operation can be performed only without the tape running.

Referring to fig. 1, a frame attaching apparatus 10 according to a preferred embodiment of the present invention includes a cutting mechanism 100, a composite roll 200, and a transfer attaching mechanism 300.
The cutting mechanism 100 can cut the CCM material strip 20 to obtain CCM sheet materials; the frame material belt 30 to be attached can be wound around the composite roller 200; the transfer/bonding mechanism 300 is located between the cutting mechanism 100 and the composite roll 200, and is capable of transferring CCM sheet material obtained by cutting by the cutting mechanism 100 to the composite roll 200 and bonding the CCM sheet material to the frame material tape 30. The composite strip is fed from the composite roll 200 after lamination, and includes the frame strip 30 and the CCM sheet stock laminated in sequence to the frame strip 30. The composite material belt can be led out through the roller so as to enter the next working procedure.
The cutting mechanism 100 includes a knife roll 110 and a bottom roll 120 which are oppositely arranged, and a gap for the CCM material strip 20 to pass through is formed between the knife roll 110 and the bottom roll 120. The knife roll 110 and the bottom roll 120 are typically rotated by separate drives, such as servo motors. Further, the knife roll 110 and the bottom roll 120 rotate at the same linear speed.
Referring to fig. 2, the outer surface of the knife roll 110 is provided with knife lines 111, and the knife lines 111 enclose a cutting pattern 112 on the outer surface of the knife roll 110. Specifically, the CCM tape 20 may pass through the gap between the knife roll 110 and the bottom roll 120 via the over roll. At this time, the CCM material strip 20 is pressed by the knife line 111 of the knife roll 110 and is sequentially cut into a plurality of CCM sheet materials, and the CCM sheet materials are matched with the cutting patterns 112 on the surface of the knife roll 110. The outer surface of the knife roll 110 in this embodiment is formed with two cutting patterns 112, so that two CCM sheets will be cut per rotation of the knife roll 110.
The bottom roll 120 has an adsorption function, and may be a vacuum roll capable of adsorbing CCM web by negative pressure. The bottom roll 120 is load bearing and supports the CCM strip 20 as the knife roll 110 cuts. And the cut CCM sheet can be adsorbed to the bottom roller 120 and rotated with the bottom roller 120.
Referring to fig. 3, in the present embodiment, there is no skip distance between two adjacent CCM sheets 21 obtained by cutting the CCM material strip 20 by the knife roll 110. Specifically, two adjacent cutting patterns 112 on the surface of the knife roll 110 abut against each other, and are separated by only one knife line 111, so that there is no skip distance between two adjacent CCM sheets 21 obtained by cutting, that is, the two adjacent CCM sheets 21 are just cut without generating waste materials. Therefore, the waste of materials can be obviously reduced, and the cost is reduced.
In addition, the CCM strip 20 is cut by the cutting mechanism 100, and waste is generated at the edges of the two sides. Therefore, the cutting mechanism 100 generally further includes a waste discharge roller 130, and the waste material formed by cutting is wound up by the waste discharge roller 130.
The compound roller 200 is also typically driven by a separate drive, such as a servo motor. The frame material tape 30 to be bonded is generally coated with hot melt adhesive in advance during preparation, so the composite roller 200 may be a heating roller. Thus, as the border strip 30 is wrapped around the composite roll 200, the composite roll 200 is able to activate the hot melt adhesive on the border strip 20 by heating to facilitate bonding with the CCM sheet stock 21. Of course, if the initial viscosity of the frame material tape 30 is high, the composite roll 200 may be a common press roll.
Referring to fig. 4, a plurality of hollow portions 31 are sequentially formed in the frame material tape 30 in the extending direction. When the CCM sheets 21 are bonded, the CCM sheets need to be aligned with the hollow portions 31 and bonded in sequence. The linear speed of the composite roll 200 is generally greater than the linear speed of the bottom roll 120, so that the tape running speed of the frame tape 30 is greater than the tape running speed of the CCM tape 20. Thus, the CCM sheet 21 without skip distance can be attached to the spaced hollow portions 31 of the frame material tape 30.
Referring again to fig. 1, the transfer and bonding mechanism 300 includes a transfer assembly 310, a plurality of transfer rollers 320, and a plurality of driving assemblies 330.
The plurality of transfer rollers 320 are mounted on the transfer assembly 310, and each transfer roller 320 is capable of rotating. The plurality of transfer rollers 320 and the plurality of driving assemblies 330 are disposed in a one-to-one correspondence, so the number of the driving assemblies 330 is the same as that of the transfer rollers 320, for example, two driving assemblies 330 are provided for two transfer rollers 320 in the embodiment.
Further, the transferring assembly 310 can drive the transferring rollers 320 to sequentially pass through the material receiving position and the attaching position, and along with the fact that any transferring roller 320 enters the material receiving position, another transferring roller 320 enters the attaching position. That is, when one of the transfer rollers 320 enters the receiving position, the other transfer roller 320 enters the attaching position.
As shown in fig. 1, the receiving position refers to a position where the transfer roller 320 is close to the bottom roller 120, i.e., the left side in fig. 1. At this time, the transfer roller 320 can engage with the bottom roller 120, and the transfer roller 320 can abut against the CCM sheet material 21 on the bottom roller 120, thereby obtaining the CCM sheet material 21 on the bottom roller 120; the fitting position refers to a position where the transfer roll 320 is close to the composite roll 200, i.e., the right side as viewed in fig. 1. At this time, the transfer roller 320 can engage with the composite roller 200, and the transfer roller 320 presses the CCM sheet 21 sucked onto the frame tape 30 wound around the composite roller 200, thereby bonding the CCM sheet 21 to the frame tape 30.
The transfer roll 320 may also be a vacuum roll, and the CCM sheet 21 on the surface of the base roll 120 is obtained by the action of negative pressure suction. Further, when the transfer roller 320 is engaged with the bottom roller 120 to take the CCM sheet 21 on the surface of the bottom roller 120, the degree of vacuum of the transfer roller 320 is greater than that of the bottom roller 120. When the transfer roller 320 cooperates with the composite roller 200 to attach the CCM sheet 21 to the frame tape 30, the transfer roller 320 releases the CCM sheet 21 by breaking the vacuum.
In this embodiment, the transferring assembly 310 is a rotating table, the transferring rollers 320 are arranged around the rotating shaft of the rotating table at equal intervals, and the rotating table can rotate at every time by a preset angle to drive the transferring rollers 320 to sequentially pass through the material receiving position and the attaching position.
The angle of the interval between the adjacent two transfer rollers 320 is equal to the preset angle. Taking the example shown in fig. 1, there are two transfer rollers 120, and the two transfer rollers 120 are spaced 180 degrees apart. When the turntable rotates 180 degrees, the two transfer rollers 320 will change their positions, the transfer roller 120 originally located at the receiving position will enter the bonding position, and the transfer roller 120 originally located at the bonding position enters the receiving position.
Obviously, the number of the transfer rollers 320 may be two or more. For example, when the transfer rollers 320 are provided in four, adjacent two transfer rollers 320 are spaced apart by 90 degrees. Correspondingly, the turntable only needs to rotate 90 degrees at each time, and then two new transfer rollers 320 can be driven to respectively enter the material receiving position and the fitting position.
It should be noted that in other embodiments, the transfer module 310 may also be a circular transfer module, and the circular transfer module passes through the receiving position and the attaching position. The plurality of transfer rollers 320 are disposed at equal intervals on the endless conveying module and can be moved along the endless conveying module in synchronization. Under the driving of the ring-shaped conveying module, the plurality of transfer rollers 320 can also sequentially pass through the material receiving position and the fitting position.
Further, when the transfer roller 320 is matched with the bottom roller 120, the driving assembly 330 can drive the transfer roller 320 to revolve around the bottom roller 120; when the transfer roller 320 is matched with the composite roller 200, the driving component 330 can drive the transfer roller 320 to revolve around the composite roller 200.
In this embodiment, each driving assembly 330 includes a first driving member (not shown) and an arc-shaped guide rail 331, each transfer roller 320 is mounted on the corresponding arc-shaped guide rail 331 and can slide along the arc-shaped guide rail 331 under the driving of the first driving member, and when the transfer roller 320 is engaged with the bottom roller 120 or the composite roller 200, the circle center of the arc-shaped guide rail 331 coincides with the circle center of the bottom roller 120 or the composite roller 200, respectively.
The first drive member may be a servo motor. When the transfer roller 320 is located at the receiving position and abuts against the bottom roller 120, the first driving member drives the transfer roller 320 to slide along the arc-shaped guide rail 331, so that the transfer roller 320 can revolve around the bottom roller 120. Similarly, when the transfer roller 320 is in the contact position and is in contact with the composite roller 200, the first driving member drives the transfer roller 320 to slide along the arc-shaped guide rail 331, so that the transfer roller 320 can revolve around the composite roller 200.
Specifically, the direction in which the transfer roller 320 revolves around the bottom roller 120 is opposite to the direction in which the bottom roller 120 rotates. As the bottom roller 120 rotates clockwise as shown in fig. 1, the transfer roller 320 revolves counterclockwise around the bottom roller 120. When the transfer roller 320 is just matched with the bottom roller 120, the transfer roller 320 is located at the position shown by the dotted line in the figure, which is called as a material receiving starting position; when the CCM sheet 21 on the bottom roller 120 is completely transferred onto the transfer roller 320, the transfer roller 320 revolves to the position shown by the solid line in the figure, which is referred to as a receiving completion position.
Since the transfer roller 320 can revolve around the bottom roller 120 in the process of taking out the CCM sheet material 21 on the bottom roller 120, the time required for the transfer roller 320 to take out one CCM sheet material 21 will be less than one cutting cycle of the cutting mechanism 100. The cutting cycle refers to a period of time during which one CCM sheet 21 is cut and transferred to the receiving start position along with the bottom roller 120. During this time difference, the transfer roller 320 can transfer the CCM sheet 21 to the attaching position, and at the same time, move the empty transfer roller 320 to the receiving position in preparation for the next acquisition of the CCM sheet 21. Moreover, the empty transfer roller 320 moves to the receiving position, and the CCM sheet 21 next to and above the bottom roller 120 has not been transferred to the receiving start position.
Likewise, when the complex roller 200 rotates counterclockwise, the transfer roller 320 revolves clockwise around the complex roller 200. Immediately after the transfer roll 320 is mated with the composite roll 200, the transfer roll 320 is located at the position indicated by the dotted line in the figure, which is referred to as a bonding start position; when the CCM sheet 21 on the transfer roller 320 is attached to the frame tape 30, the transfer roller 320 revolves to the position shown by the solid line in the figure, which is referred to as the attachment completion position. Correspondingly, the time required to apply a CCM sheet will also be less than one cutting cycle of the cutting mechanism 100.
When one CCM sheet 21 is completely attached, the next region to be attached (the region corresponding to the next hollow portion 31) of the frame material tape 30 is shifted from the attachment completion position to the attachment start position. Further, the next region to be bonded has not been transferred to the bonding start position before the transfer roller 320, which has attracted the CCM sheet 21, enters the bonding position. Thus, by utilizing the time difference, the transfer and bonding mechanism 300 can continuously transfer the CCM sheet materials 21, so that the frame material tape 30 and the CCM material tape 20 can be continuously transported in the bonding process, thereby significantly improving the production efficiency of the fuel cell.
In this embodiment, when the transfer roller 320 is located at the receiving position, the driving assembly 330 can drive the transfer roller 320 to approach or separate from the bottom roller 120, so that the transfer roller 320 is engaged with or separated from the bottom roller 120; with the transfer roll 320 in the engaged position, the drive assembly 330 can drive the transfer roll 320 toward or away from the composite roll 200 to engage or disengage the transfer roll 320 from the composite roll 200.
That is, the transfer roller 320 is not matched with the bottom roller 120 and the composite roller 200 as soon as the transfer roller enters the receiving position and the bonding position, and a gap is formed between the transfer roller 320 and the bottom roller 120 and the composite roller 200 after the transfer roller is separated from the bottom roller 120 and the composite roller 200. Therefore, the transfer component 310 can conveniently drive the plurality of transfer rollers 320 to move, and interference is avoided.
It should be noted that in other embodiments, the position of the transfer roller 320 can be precisely adjusted, and the transfer roller 320 can be matched with the bottom roller 120 and the composite roller 200 once entering the receiving position and the fitting position, so that the driving assembly 330 is not needed for driving.
Further, in this embodiment, each of the transfer rollers 320 is provided with a driven gear (not shown), the bottom roller 120 is provided with a first driving gear (not shown), and the compound roller 200 is provided with a second driving gear (not shown). When the transfer roller 320 is matched with the bottom roller 120, the driven gear is meshed with the first driving gear; the driven gear engages the second drive gear when the transfer roll 320 is engaged with the compound roll 200.
When the driven gear is meshed with the first driving gear, the synchronization of the transfer roller 320 and the bottom roller 120 can be realized, so that the rotating speed inconsistency of the transfer roller 320 and the bottom roller 120 in the material receiving process is avoided. When the driven gear is meshed with the second driving gear, the transfer roller 320 and the composite roller 200 can be synchronized, so that the rotating speed of the transfer roller 320 and the rotating speed of the composite roller are not consistent in the fitting process.
In this embodiment, each driving assembly 330 further includes a linear guide 332 and a second driving element (not shown), and the arc-shaped guide 331 is mounted on the linear guide 332 and can move along the linear guide 332 under the driving of the second driving element.
When the transferring assembly 310 drives the transferring roller 320 to enter the receiving position, the second driving member drives the arc-shaped guide rail 331 to move along the linear guide rail 332, so as to drive the transferring roller 320 to approach or separate from the bottom roller 120, thereby engaging or disengaging the transferring roller 320 with or from the bottom roller 120. When the transfer assembly 310 drives the transfer roller 320 to enter the fitting position, the second driving member drives the arc-shaped guide rail 331 to move along the linear guide rail 332, so as to drive the transfer roller 320 to approach or separate from the composite roller 200, thereby engaging or disengaging the transfer roller 320 with or from the composite roller 200.
Further, in this embodiment, each driving assembly 330 further includes a rotation driving unit (not shown) which drives the corresponding transfer roller 320 to rotate by a clutch (not shown), and the clutch is disengaged when the transfer roller 320 is engaged with the bottom roller 120 or the composite roller 200.
Before the transfer roller 320 is matched with the bottom roller 120 and the composite roller 200, the transfer roller 320 can rotate under the driving of a rotation driving piece, so that the rotation speed of the transfer roller 320 is close to or equal to the rotation speed of the composite roller 200 and the bottom roller 120. Thus, at the moment the transfer roller 320 is matched with the bottom roller 120 or the composite roller 200, the phenomena of slipping and the like caused by overlarge rotation speed difference between the transfer roller 320 and the composite roller 200 or the bottom roller 120 can be prevented, and the influence on material receiving and bonding is further prevented. After the transfer roller 320 is engaged with the base roller 120 and the composite roller 200, the clutch is disengaged, so that the rotation driving unit drives the transfer roller 320 to be disengaged, and the transfer roller 320 rotates together with the base roller 120 and the composite roller 200.
Referring to fig. 1 again, in the present embodiment, the frame pasting apparatus 10 further includes a position sensor 400, the position sensor 400 can scan the surface of the composite roll 200 and obtain the position information of the frame material belt 30, and the driving assembly 330 can adjust the position of the transfer roll 320 according to the position information, so as to align the CCM sheet 21 and the frame material belt 30.
The position sensor 400 may be a CCD camera, and obtains the position information of the frame tape 30 by photographing. The aim of counterpoint is through the adjustment laminating initial position for the position of CCM sheet stock 21 and the fretwork portion 31 of frame material area 30 corresponds, thereby guarantees the laminating precision.
In the frame bonding apparatus 10, the transfer roller 320 can transfer the CCM sheet 21 to the bonding position for bonding after the CCM sheet 21 on the bottom roller 120 is taken in the receiving position. Since the transfer roller 320 can revolve around the bottom roller 120 in the acquisition process of acquiring the CCM sheet material 21, the time required for the transfer roller 320 to acquire one CCM sheet material 21 will be less than one cutting cycle of the cutting mechanism 100. Also, the transfer roller 320 can revolve around the laminating roller 200 during the laminating process, so that the time required for laminating one CCM sheet 21 can be shortened. Within the generated time difference, the transfer roller 320 can transfer the CCM sheet 21 to the attaching position, and move the empty transfer roller 320 to the receiving position in preparation for acquisition of the next CCM sheet 21. Therefore, the frame material belt 30 and the CCM material belt 20 can both realize continuous belt conveying, so that the production efficiency of the fuel cell is obviously improved.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
