Abstract
The invention relates to a frame attaching device which comprises a cutting mechanism, a composite roller and a transferring attaching mechanism. After the transfer roller obtains the CCM sheet materials on the bottom roller at the receiving position, the CCM sheet materials can be transferred to the attaching position for attaching. Since the transfer roller is capable of revolving around the bottom roller during the acquisition of CCM flakes, the time required for the transfer roller to acquire one CCM flake will be less than one cutting cycle of the cutting mechanism. Likewise, the transfer roll can revolve around the composite roll during the bonding process, so the time required to bond one CCM sheet will also be reduced. Within the time difference created, the transfer roller is able to transfer the CCM sheet to the bonding position and move the empty transfer roller to the receiving position in preparation for the next CCM sheet acquisition. Thus, the frame material belt and the CCM material belt can realize continuous tape feeding, thereby remarkably improving the production efficiency of the fuel cell.
Description
Technical Field
The invention relates to the technical field of fuel cell processing equipment, in particular to a frame attaching device.
Background
In the production process of the fuel cell, the frames are attached to two sides of the CCM (catalyst coated membrane, catalyst/proton exchange membrane module) to obtain the five-in-one module. The manner in which CCMs are attached to the frame generally includes piece-to-piece attachment and discontinuous roll-to-roll attachment.
In the piece-to-piece bonding mode, CCM and frame incoming materials are piece materials, and a semi-finished product after the CCM and the first frame are aligned and bonded is bonded with the other frame. In the discontinuous roll-to-roll bonding mode, the frame material is roll material, and the CCM material can also be roll material. At this time, it is necessary to perform half-cut on the apparatus and obtain a single CCM with a skip distance, and then to waste the waste at the skip distance. Then, the single CCM and the two layers of frames are sequentially attached.
In the process of sheet-to-sheet lamination, the CCM and the frame for each sheet need to be positioned and aligned. In the discontinuous roll-to-roll bonding method, the bonding operation can be performed only without tape running. Therefore, the conventional lamination method may result in low production efficiency of the fuel cell.

Referring to fig. 1, a frame attaching device 10 according to a preferred embodiment of the present invention includes a cutting mechanism 100, a compounding roller 200, and a transfer attaching mechanism 300.
The cutting mechanism 100 is capable of cutting the CCM web 20 to obtain CCM sheets; the frame material tape 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 roller 200, and is capable of transferring the CCM sheet obtained by cutting by the cutting mechanism 100 to the composite roller 200 and bonding the CCM sheet to the frame material tape 30. After bonding, the composite material tape is output by the composite roller 200, and comprises a frame material tape 30 and CCM (continuous composite material) sheet materials sequentially bonded to the frame material tape 30. The composite tape can be guided out through a roller so as to enter the next working procedure.
The cutting mechanism 100 includes a cutter roll 110 and a bottom roll 120 disposed opposite to each other, and a gap is provided between the cutter roll 110 and the bottom roll 120 for the CCM material belt 20 to pass through. The knife roll 110 and the base roll 120 are typically rotated by separate drives, such as servo motors. The linear velocity at which the knife roll 110 and the base roll 120 rotate is the same.
Referring to fig. 2, the outer surface of the cutter roller 110 is provided with cutter lines 111, and the cutter lines 111 enclose a cutting pattern 112 on the outer surface of the cutter roller 110. Specifically, CCM web 20 may pass through the gap between knife roll 110 and bottom roll 120 via a pass-through roll. At this time, the CCM material ribbon 20 is sequentially cut into a plurality of CCM sheets by being pressed by the cutter wire 111 of the cutter roll 110, and the CCM sheets are matched with the cutting pattern 112 on the surface of the cutter roll 110. The outer surface of the cutter roll 110 in this embodiment is formed with two cutting patterns 112, so that two CCM sheets will be cut per rotation of the cutter roll 110.
The bottom roller 120 has an adsorption function and may be a vacuum roller capable of adsorbing CCM sheet material by negative pressure. The bottom roll 120 serves as a load bearing function to support the CCM tape 20 as the knife roll 110 cuts. And the cut CCM sheet can be sucked to the bottom roller 120 and rotated with the bottom roller 120.
Referring to fig. 3, in the present embodiment, there is no jump distance between two adjacent CCM sheets 21 obtained by cutting the CCM material ribbon 20 by the cutter roll 110. Specifically, the two adjacent cutting patterns 112 on the surface of the cutter roller 110 are abutted against each other, and the middle is separated by only one cutter line 111, so that no jump exists between the two adjacent CCM sheets 21 obtained by cutting, that is, the two adjacent CCM sheets 21 are just cut off without waste. Therefore, the waste of materials can be obviously reduced, and the cost is reduced.
In addition, after the CCM tape 20 is cut by the cutting mechanism 100, the edges on both sides generate waste. Accordingly, the cutting mechanism 100 also typically includes a waste discharge roller 130, and the waste material formed by cutting is wound up by the waste discharge roller 130.
The composite roll 200 is also typically driven by a separate drive, such as a servo motor. The frame material tape 30 to be attached is typically pre-coated with a hot melt adhesive at the time of preparation, so the composite roll 200 may be a heated roll. Thus, as the border strip 30 passes around the laminating roller 200, the laminating roller 200 is able to activate the hot melt adhesive on the border strip 20 by heating to facilitate its bonding to the CCM sheet 21. Of course, if the initial adhesiveness of the frame material strip 30 is high, the laminating roller 200 may be a conventional pressing roller.
Referring to fig. 4, the frame material strip 30 is sequentially formed with a plurality of hollowed-out portions 31 along the extending direction. In the bonding, the CCM sheets 21 are required to be aligned with and bonded to the hollowed-out portions 31 in sequence. The linear velocity of the composite roll 200 is generally greater than the linear velocity of the bottom roll 120 such that the tape travel speed of the border strip 30 is greater than the tape travel speed of the CCM strip 20. Thus, the CCM sheet 21 without the skip distance can be attached to the hollowed-out portions 31 of the frame tape 30 at intervals.
Referring again to fig. 1, the transfer attaching mechanism 300 includes a transfer assembly 310, a plurality of transfer rollers 320, and a plurality of driving assemblies 330.
A plurality of transfer rollers 320 are mounted on the transfer unit 310, and each transfer roller 320 is capable of spinning. The plurality of transfer rollers 320 and the plurality of driving units 330 are disposed in a one-to-one correspondence, so that the number of driving units 330 is the same as the number of transfer rollers 320, for example, two transfer rollers 320 in the present embodiment, two driving units 330 are also provided.
Further, the transfer assembly 310 can drive the plurality of transfer rollers 320 to sequentially pass through the receiving position and the attaching position, and as any one transfer roller 320 enters the receiving position, another transfer 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 bonding 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 as shown in fig. 1. At this time, the transfer roller 320 can be engaged with the bottom roller 120, and the transfer roller 320 can be abutted against the CCM sheet 21 on the bottom roller 120, thereby obtaining the CCM sheet 21 on the bottom roller 120; the bonding position refers to a position where the transfer roller 320 is close to the composite roller 200, i.e., the right side as shown in fig. 1. At this time, the transfer roller 320 can be engaged with the composite roller 200, and the transfer roller 320 can abut the adsorbed CCM sheet 21 against 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 bottom roll 120 is obtained by suction of negative pressure. Also, when the transfer roller 320 is mated with the bottom roller 120 to obtain the CCM sheet 21 of the surface of the bottom roller 120, the vacuum degree of the transfer roller 320 is greater than that of the bottom roller 120. When the transfer roller 320 cooperates with the compounding roller 200 to attach the CCM sheet 21 to the frame tape 30, the transfer roller 320 may release the adsorbed CCM sheet 21 by breaking the vacuum.
In this embodiment, the transferring assembly 310 is a turntable, and the plurality of transferring rollers 320 are disposed at equal intervals around a rotation axis of the turntable, and the turntable can rotate a preset angle each time to drive the plurality of 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 above-mentioned 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 positions, the transfer roller 120 originally located at the receiving position will enter the attaching position, and the transfer roller 120 originally located at the attaching position will enter the receiving position.
Obviously, the number of 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 can drive the two new transfer rollers 320 to enter the material receiving position and the attaching position respectively only by rotating 90 degrees each time.
It should be noted that in other embodiments, the transfer assembly 310 may be an endless conveyor module, and the endless conveyor module passes through the material receiving position and the attaching position. The plurality of transfer rollers 320 are disposed at equal intervals on the endless conveyor module and can move synchronously along the endless conveyor module. The plurality of transfer rollers 320 may also sequentially pass through the receiving position and the attaching position under the driving of the endless conveyor.
Further, when the transfer roller 320 is engaged 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 and the composite roller 200 are in contact, the driving assembly 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 rail 331, each transfer roller 320 is mounted on the corresponding arc-shaped rail 331 and can slide along the arc-shaped rail 331 under the driving of the first driving member, and when the transfer roller 320 is matched with the bottom roller 120 or the composite roller 200, the center of the arc-shaped rail 331 coincides with the center of the bottom roller 120 or the composite roller 200, respectively.
The first driving 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 located at the bonding position and abuts against 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 shown in fig. 1, the bottom roller 120 rotates clockwise, and the transfer roller 320 revolves counterclockwise around the bottom roller 120. When the transfer roller 320 is just engaged with the bottom roller 120, the transfer roller 320 is located at a position indicated by a broken line in the drawing, which is called a stock receiving start position; when the CCM sheet 21 on the bottom roller 120 is completely transferred to the transfer roller 320, the transfer roller 320 revolves to a solid line position shown in the figure, which is called a stock finishing position.
Since the transfer roller 320 is able to revolve around the bottom roller 120 during the process of taking a CCM sheet 21 on the bottom roller 120, the time required for the transfer roller 320 to take one CCM sheet 21 will be less than one cutting cycle of the cutting mechanism 100. The cutting cycle refers to the length of time that one CCM sheet 21 is cut and transferred to the take-up start position with the bottom roll 120. Within this time difference, the transfer roller 320 is able to transfer the CCM sheet 21 to the lay-up position and simultaneously move the empty transfer roller 320 to the take-up position in preparation for the next CCM sheet 21 to be taken. Moreover, the empty transfer roller 320 is moved to the take-up position, and the next CCM sheet 21 on the bottom roller 120 has not yet been transferred to the take-up start position.
Similarly, when the composite roller 200 rotates counterclockwise, the transfer roller 320 revolves clockwise around the composite roller 200. When the transfer roller 320 and the composite roller 200 are just engaged, the transfer roller 320 is located at a position indicated by a broken line in the figure, which is referred to as an engagement 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 solid line position shown in the figure, which is called an attachment completion position. Correspondingly, the time required to attach a CCM sheet will also be less than one cutting cycle of cutting mechanism 100.
When one CCM sheet 21 completes bonding, the next region to be bonded (the region corresponding to the next hollowed-out portion 31) of the frame material tape 30 will be shifted from the bonding completion position to the bonding start position. Moreover, the next area to be bonded is not transferred to the bonding start position before the transfer roller 320 having adsorbed the CCM sheet 21 enters the bonding position. Thus, by using the above time difference, the transfer lamination mechanism 300 can continuously transfer the CCM sheet 21, so that the frame material belt 30 and the CCM material belt 20 can be continuously fed in the lamination process, thereby remarkably 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; when the transfer roller 320 is in the engaged position, the drive assembly 330 can drive the transfer roller 320 toward or away from the composite roller 200 to engage or disengage the transfer roller 320 from the composite roller 200.
That is, the transfer roller 320 is not engaged with the bottom roller 120 and the composite roller 200 as soon as it enters the joining position and the bonding position, and a gap is generated between the transfer roller 320 and the bottom roller 120 and the composite roller 200 after being separated from the bottom roller 120 and the composite roller 200. In this way, the transfer assembly 310 can conveniently drive the plurality of transfer rollers 320 to move, so that interference is avoided.
It should be noted that in other embodiments, the position of the transfer roller 320 may be precisely adjusted, and the transfer roller 320 may be engaged with the bottom roller 120 and the composite roller 200 once it is in the receiving position and the bonding position, such that the drive assembly 330 is not required.
Further, in the present embodiment, a driven gear (not shown) is disposed on each of the transfer rollers 320, a first driving gear (not shown) is disposed on the bottom roller 120, and a second driving gear (not shown) is disposed on the composite roller 200. Wherein, when the transfer roller 320 is matched with the bottom roller 120, the driven gear is meshed with the first driving gear; when the transfer roller 320 is engaged with the complex roller 200, the driven gear is engaged with the second driving gear.
When the driven gear is meshed with the first driving gear, synchronization of the transfer roller 320 and the bottom roller 120 can be achieved, and accordingly, inconsistent rotation speeds of the transfer roller 320 and the bottom roller 120 in the material receiving process are avoided. When the driven gear is meshed with the second driving gear, synchronization of the transfer roller 320 and the composite roller 200 can be achieved, and accordingly inconsistent rotation speeds of the transfer roller 320 and the composite roller in the attaching process are avoided.
In this embodiment, each driving assembly 330 further includes a linear guide 332 and a second driving member (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 member.
When the transfer assembly 310 drives the transfer roller 320 to enter the receiving position, the second driving member drives the arc-shaped rail 331 to move along the linear rail 332, so as to drive the transfer roller 320 to approach or separate from the bottom roller 120, thereby engaging or disengaging the transfer roller 320 with or from the bottom roller 120. When the transfer assembly 310 drives the transfer roller 320 to enter the attaching position, the second driving member drives the arc-shaped rail 331 to move along the linear rail 332, so as to drive the transfer roller 320 to approach or separate from the composite roller 200, thereby enabling the transfer roller 320 to be engaged with or separated from the composite roller 200.
Further, in the present embodiment, each driving assembly 330 further includes a rotation driving member (not shown), and the rotation driving member drives the corresponding transfer roller 320 to rotate through a clutch (not shown), and when the transfer roller 320 is engaged with the bottom roller 120 or the composite roller 200, the clutch is disengaged.
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 the rotation driving member, so that the rotation speed of the transfer roller 320 is close to or equal to the rotation speeds of the composite roller 200 and the bottom roller 120. In this way, at the moment when the transfer roller 320 is engaged with the bottom roller 120 or the composite roller 200, slipping or the like due to an excessive difference in rotational speed between the transfer roller 320 and the composite roller 200 or the bottom roller 120 can be prevented, and the material receiving and bonding can be prevented from being affected. After the transfer roller 320 is engaged with the bottom roller 120 and the composite roller 200, the clutch is disengaged, so that the rotation driving member is disengaged from the transfer roller 320, and the transfer roller 320 rotates along with the bottom roller 120 and the composite roller 200.
Referring to fig. 1 again, in the present embodiment, the frame attaching device 10 further includes a position sensor 400, the position sensor 400 can scan the surface of the composite roller 200 and obtain the position information of the frame material belt 30, and the driving assembly 330 can adjust the position of the transfer roller 320 according to the position information, so that the CCM sheet 21 and the frame material belt 30 are aligned.
The position sensor 400 may be a CCD camera, and obtains the position information of the bezel web 30 by photographing. The purpose of counterpoint is through adjusting laminating initial position for CCM sheet 21 corresponds with the position of the fretwork portion 31 of frame material area 30, thereby guarantees laminating precision.
In the frame bonding apparatus 10, the transfer roller 320 obtains the CCM sheet 21 on the bottom roller 120 at the bonding position, and then transfers the CCM sheet 21 to the bonding position to bond the two. Since the transfer roller 320 is able to revolve around the bottom roller 120 during the acquisition of the CCM sheet 21, the time required for the transfer roller 320 to acquire one CCM sheet 21 will be less than one cutting cycle of the cutting mechanism 100. Likewise, the transfer roller 320 is able to revolve around the composite roller 200 during the lamination process, so the time required to laminate one CCM sheet 21 will also be reduced. Within the time difference created, the transfer roller 320 is able to transfer the CCM sheet 21 to the bonding position and move the empty transfer roller 320 to the receiving position in preparation for the next CCM sheet 21 acquisition. Thus, the frame material belt 30 and the CCM material belt 20 can both realize continuous belt feeding, thereby remarkably improving the production efficiency of the fuel cell.
