Abstract

The invention relates to a five-in-one forming device, wherein after a transfer roller obtains a CCM sheet material on a bottom roller at a receiving position, the CCM sheet material can be transferred to a bonding position for bonding, and an obtained first composite material belt is bonded with a lower frame material belt at a second composite roller, so that the forming of the five-in-one material belt is realized. Since the transfer roller is able to revolve around the bottom roller during the process of obtaining a CCM sheet, the time required for the transfer roller to obtain one CCM sheet will be less than one cutting cycle of the cutting mechanism. Likewise, the transfer roll is able to revolve around the first composite roll during the lamination process, so the time required to laminate 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 upper frame material belt, the lower frame material belt and the CCM material belt can all realize continuous tape feeding in the process of five-in-one material belt forming, thereby remarkably improving the production efficiency of the fuel cell.

Technical Field

The invention relates to the technical field of fuel cell processing equipment, in particular to a five-in-one forming device.

Background

The core component of the fuel cell is a MEA (Membrane Electrode Assembly) membrane electrode, also known as a seven-in-one assembly. The seven-in-one assembly comprises a CCM (catalyst coated membrane, catalyst/proton exchange membrane assembly), a frame attached to both sides of the CCM and a gas diffusion layer.

Referring to fig. 1, a five-in-one forming apparatus 10 according to a preferred embodiment of the present invention includes a cutting mechanism 100, a first frame making mechanism 200, a first composite roller 300, a second frame making mechanism 400, a second composite roller 500, and a transfer bonding mechanism 600.

The five-in-one forming apparatus 10 is used to prepare a five-in-one web (not shown) as shown in fig. 4, which includes an upper rim web 30, a lower rim web 40, and a plurality of CCM sheets 21.CCM refers to a catalyst/proton exchange membrane assembly comprising a proton membrane and catalyst layers coated on both sides of the proton membrane. The plurality of CCM sheets 21 are sandwiched between the upper frame tape 30 and the lower frame tape 40 and are arranged at intervals along the extending direction of the five-in-one tape. The outermost layers on both sides of the five-in-one material tape are generally attached with a first protective film material tape 31 and a second protective film material tape 42 to protect the five-in-one material tape. The five-in-one material tape and the first protective film material tape 31 and the second protective film material tape 42 together form a second composite material tape 60. In the next step, the first protective film material 31 and the second protective film material 42 are removed.

The upper frame strip 30 and the lower frame strip 40 may be identical in structure. As shown in fig. 5 and 6, the upper frame material belt 30 is formed with first inner frames 301 arranged at intervals along the length direction, and the area where the first inner frames 301 are located is hollowed out; and the lower frame material tape 40 is formed with second inner frames (not shown) arranged at intervals in the length direction. In the five-in-one material belt, the first inner frame 301 and the second inner frame are aligned one by one, and two sides of each CCM sheet 21 are respectively attached to the first inner frame 301 and the second inner frame, so that a plurality of spaced functional areas are formed along the extending direction of the five-in-one material belt. In operation of the fuel cell, the reactant gases are capable of undergoing chemical reactions at the functional regions to produce electrical energy.

Referring again to fig. 1, the cutting mechanism 100 is capable of cutting the CCM web 20 to obtain CCM pellets 21; the frame material belt 30 on the first frame making mechanism 200 can pass through the first compound roller 300; the lower frame material belt 40 provided by the second frame making mechanism 400 can pass around the second compound roller 500; the transfer bonding mechanism 600 is located between the cutting mechanism 100 and the first composite roller 300, and is capable of transferring the CCM sheet 21 obtained by cutting by the cutting mechanism 100 to the first composite roller 300, and bonding the CCM sheet 21 to the upper frame material tape 30, thereby obtaining the first composite material tape 50 shown in fig. 3. The first composite web 50 is able to pass around the second composite roll 500 and achieve a roll-to-roll fit with the lower rim web 40, resulting in a second composite web 60 as shown in fig. 5 and comprising five-in-one webs.

Referring to fig. 7 and 8, the cutting mechanism 100 includes a cutter roller 110 and a bottom roller 120 disposed opposite to each other, and a gap is provided between the cutter roller 110 and the bottom roller 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.

The outer surface of the cutter roll 110 is provided with cutter lines 111, and the cutter lines 111 enclose a cutting pattern 112 on the outer surface of the cutter roll 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 tape 20 is sequentially cut into a plurality of CCM sheets 21 by being pressed by the cutter wire 111 of the cutter roll 110, and the CCM sheets 21 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 21 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 the CCM sheet 21 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 21 can be adsorbed to the bottom roller 120 and rotated with the bottom roller 120.

As shown in fig. 2, in the present embodiment, there is no jump distance between two adjacent CCM sheets 21 obtained by cutting the CCM tape 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 generally further includes a waste discharge member 130 and a waste bin 140, wherein the waste discharge member 130 may be a driven nip roller, and the waste formed by cutting is fed from the waste discharge member 130 into the waste bin 140.

Referring to fig. 7 again, in the present embodiment, the five-in-one forming apparatus 10 further includes a CCM unreeling mechanism 700, the CCM unreeling mechanism 700 includes two CCM unreeling shafts 710 and a CCM tape connecting mechanism 720, and the two CCM unreeling shafts 710 can unreel the CCM material tapes 20 respectively and output to the cutting mechanism 100 through the CCM tape connecting mechanism 720.

The CCM web 20 output by the CCM taping mechanism 720 may pass through a roller, tension measuring mechanism (not shown) and then into the cutting mechanism 100. After the CCM tape 20 on the first CCM reel 710 is completely paid out, the CCM tape 20 on the second CCM reel 710 may be spliced to the end of the first CCM tape 20 by the CCM tape splicing mechanism 720, and the first CCM reel 710 may be replaced. In this way, the continuity of the supply of the CCM strip 20 can be ensured, so that the five-in-one forming device 10 can be operated continuously.

The surface of the CCM material tape 20 wound on the CCM unwinding shaft 710 is generally covered with a protective film material tape (not shown), so the CCM unwinding mechanism 700 further includes two protective film winding shafts 730 for synchronously winding the protective film material tape during the process of unwinding the CCM material tape 20.

The first framing mechanism 200 is used for providing the upper frame material tape 30. As described above, the upper frame material tape 30 is formed with the first inner frames 301 arranged at intervals in the length direction. As shown in fig. 6, the first inner frames 301 are generally rectangular, and a plurality of two first inner frames 301 are disposed at equal intervals.

Referring to fig. 9, in the present embodiment, the first framing mechanism 200 includes a first unreeling shaft 210, a first frame component 220, and a first debonding component 230.

The first unreeling shaft 210 is used for unreeling the third composite material belt 70, the third composite material belt 70 comprises a first protective film material belt 31, photosensitive glue is arranged on one side of the first protective film material belt 31, and the upper frame material belt 30 is adhered to the first protective film material belt 31 through the photosensitive glue. The photosensitive adhesive is sensitive to light, and can reduce or eliminate the viscosity under the irradiation of curing light. Specifically, the photosensitive paste may be a UV paste, and the viscosity reduction may be achieved by ultraviolet irradiation. In addition, the photosensitive paste may be a visible light curable paste, an electron beam curable paste, or the like. The first protective film material belt 31 can protect and support the upper frame material belt 30 in the framing process, and can protect one side of the five-in-one material belt after the five-in-one material belt is formed.

The third composite strip 70 unwound from the first unwind spool 210 may pass through rollers, tension measuring mechanisms, and deviation correcting mechanisms into the first frame assembly 220. The first inner frame 301 is not formed on the upper rim strip 30 prior to entering the first frame assembly 220. The first frame cutting assembly 220 is capable of cutting the third composite material tape 70 and obtaining the first inner frames 301 arranged at intervals along the length direction on the upper frame material tape 30. Specifically, the first frame assembly 220 includes a first cutter roller 221 and a first support roller 222.

As shown in fig. 10, the outer surface of the first cutter roller 221 is provided with a first cutter line 2211, and the first cutter line 2211 encloses a first cutting pattern 2212 on the outer surface of the first cutter roller 221. The third composite material belt 70 may pass through between the first cutter roller 221 and the first support roller 222 and be extruded by the first cutter wire 2211 to sequentially cut a plurality of first inner frames 301, and the shapes of the first inner frames 301 and the first cutting patterns 2212 are matched. Compared to the cutter roll 110, the first cutting patterns 2212 of the first cutter roll 221 surface have a space therebetween, resulting in a jump distance between the plurality of first inner frames 301 cut out.

Referring to fig. 9 again, the first debonding component 230 is configured to illuminate the third composite material tape 70 to weaken the adhesion of the photosensitive adhesive in the area corresponding to the first inner frame 301 and the first protective film material tape 31. The first debonding assembly 230 may be an ultraviolet lamp, or a curing lamp and a light shielding plate thereof, which limits the light emitting range of the curing lamp, so that the curing light can only irradiate the area corresponding to the first inner frame 301. After the viscosity of the photosensitive adhesive in the area corresponding to the first inner frame 301 and the first protective film material belt 31 is weakened, the adhesion between the first protective film material belt 31 and the CCM sheet 21 in the five-in-one material belt can be reduced, so that the catalyst layer on the surface of the CCM sheet 21 is prevented from being damaged when the first protective film material belt 31 is torn off.

In this embodiment, the first frame making mechanism 200 further includes a first waste discharging roller 240, the third composite material belt 70 output through the first frame cutting assembly 220 can pass through the first waste discharging roller 240, and the first waste discharging roller 240 can adsorb waste materials of the upper frame material belt 30 located in the first inner frame 301. The first waste discharge roller 240 may be a vacuum roller, and may adsorb and tear off the waste material of the first inner frame 301 while rolling over the surface of the upper frame material tape 30, and finally feed the waste material into the first inner frame waste bin 250.

It should be noted that, in other embodiments, the first knife roller 221 may be configured as a vacuum roller, and the first knife roller 221 may take away the waste material located in the first inner frame 301 while cutting the upper frame material belt 30, so as to omit the first waste discharge roller 240.

Further, the first debonding assembly 230 is located between the first frame assembly 220 and the first waste roller 240. That is, before the waste material of the first inner frame 301 is carried away by the first waste discharge roller 240, the adhesiveness of the photosensitive paste in the region corresponding to the first inner frame 301 of the first protective film material tape 31 is weakened. In this way, the adhesion between the scrap material and the first protective film material belt 31 will be significantly reduced, which will facilitate the first scrap discharge roller 240 to take away the scrap material.

Before the upper frame material belt 30 provided by the first frame making mechanism 200 enters the first composite roller 300, the first CCD assembly is generally required to scan the upper frame material belt 30 to detect whether the cutting is accurate, that is, whether the first inner frame 301 is of a preset shape and arranged at preset intervals. If the detection result is not in line with the expectations, the first framing mechanism 200 needs to be debugged again.

The first composite roll 300 is also typically driven by a separate drive, such as a servo motor. The upper frame tape 30 is generally coated with a hot melt adhesive in advance so as to be able to be bonded to the CCM sheet 21. Accordingly, the first compounding roll 300 may be a heating roll, and the first compounding roll 300 is capable of activating the hot melt adhesive on the upper frame tape 30 by heating when the upper frame tape 30 passes around the first compounding roll 300. Of course, if the initial adhesiveness of the upper frame material tape 30 is high, the first composite roller 300 may be a conventional pressing roller.

The linear velocity of the first composite roll 300 is generally greater than the linear velocity of the bottom roll 120 such that the feed rate of the upper rim strip 30 is greater than the feed rate of the CCM strip 20. In this way, the CCM sheet 21 without the skip distance can be attached to the first inner frame 301 spaced apart from the upper frame tape 30.

The second framing mechanism 400 is used to provide the lower frame strip 40. As described above, the lower frame material tape 40 and the upper frame material tape 30 may have the same structure, and thus the second frame making mechanism 400 may have the same structure as the first frame making mechanism 200.

Referring to fig. 11, in this embodiment, the second frame making mechanism 400 includes a second unreeling shaft 410, a second frame cutting assembly 420, a second debonding assembly 430, a second waste discharging roller 440 and a second waste box 450. Wherein the second unwind spool 410 is used to unwind a fourth composite web 80, the fourth composite web 80 may be identical in structure to the third composite web 70. Specifically, the fourth composite material belt 80 includes a second protective film material belt 42, a photosensitive adhesive is disposed on one side of the second protective film material belt 42, and the lower frame material belt 40 is adhered to the second protective film material belt 42 through the photosensitive adhesive.

Further, the structures and functions of the second frame cutting assembly 420, the second debonding assembly 430 and the second waste discharging roller 440 are the same as those of the first unwinding shaft 210, the first frame cutting assembly 220, the first debonding assembly 230 and the first waste discharging roller 240, and thus are not described herein.

The second composite roll 500 is also typically driven by a separate drive, such as a servo motor. The lower frame tape 40 is generally pre-coated with a hot melt adhesive so as to be able to be bonded to the CCM sheet 21. Accordingly, the second compounding roll 500 can be a heated roll, and the second compounding roll 500 can activate the hot melt adhesive on the lower border strip 40 by heating as the lower border strip 40 passes around the second compounding roll 500. Of course, if the initial tackiness of the lower frame material 40 is high, the upper frame material 20 may be a conventional press roll.

Referring to fig. 12, the transfer attaching mechanism 600 includes a transfer assembly 610, a plurality of transfer rollers 620, and a plurality of driving assemblies 630.

A plurality of transfer rollers 620 are mounted on the transfer assembly 610, and each transfer roller 620 is capable of spinning. The plurality of transfer rollers 620 are disposed in a one-to-one correspondence with the plurality of driving assemblies 630, so that the number of driving assemblies 630 is the same as the number of transfer rollers 620, for example, two transfer rollers 620 in the present embodiment, and two driving assemblies 630.

Further, the transfer assembly 610 can drive the plurality of transfer rollers 620 to sequentially pass through the receiving position and the attaching position, and as any one transfer roller 620 enters the receiving position, another transfer roller 620 will enter the attaching position. That is, when one of the transfer rollers 620 enters the receiving position, the other transfer roller 620 enters the attaching position, thereby ensuring that the transfer rollers 620 are simultaneously present in the receiving position and the attaching position.

As shown in fig. 12, the receiving position refers to a position where the transfer roller 620 approaches the bottom roller 120, i.e., the left side as viewed in the drawing. At this time, the transfer roller 620 can be engaged with the bottom roller 120, and the transfer roller 620 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 620 approaches the first composite roller 300, i.e., to the right as shown in the drawing. At this time, the transfer roller 620 can be engaged with the first composite roller 300, and the transfer roller 620 can press the adsorbed CCM sheet 21 against the upper frame tape 30 wound around the first composite roller 300, thereby bonding the CCM sheet 21 to the upper frame tape 30.

The five-in-one forming device 10 is generally further provided with a second CCD assembly (not shown) capable of scanning the surface of the first composite roller 300, and the second CCD assembly is capable of acquiring positional information of the frame material tape 30. The driving assembly 630 can adjust the position of the transfer roller 620 according to the position information, so that the CCM sheet 21 and the frame material belt 30 are accurately aligned, and thus the attaching precision is ensured.

As the transfer bonding mechanism 600 continues to circulate, the plurality of CCM sheets 21 cut by the cutting mechanism 100 will be sequentially bonded to the plurality of first inner frames 301 of the upper rim strip 30, thereby obtaining the first composite strip 50. The five-in-one forming device is generally further provided with a third CCD assembly capable of detecting the alignment accuracy of the CCM sheet 21 and the upper frame strip 30 in the first composite strip 50. If the alignment accuracy is not satisfactory, the five-in-one molding device needs to be debugged again, and the first composite material belt 50 is also disabled.

The transfer roll 620 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 620 cooperates 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 620 is greater than the vacuum degree of the bottom roller 120. While the transfer roll 620 cooperates with the first composite roll 300 to adhere the CCM sheet 21 to the upper rim strip 30, the transfer roll 620 may release the adsorbed CCM sheet 21 by breaking the vacuum.

In this embodiment, the transferring assembly 610 is a turntable, and the plurality of transferring rollers 620 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 620 to sequentially pass through the material receiving position and the attaching position.

The angle of the interval between the adjacent two transfer rollers 620 is equal to the above-mentioned preset angle. Taking the example shown in fig. 6, 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 620 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 620 may be two or more. For example, when the transfer rollers 620 are provided in four, adjacent two transfer rollers 620 are spaced apart by 90 degrees. Correspondingly, the turntable can drive the two new transfer rollers 620 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 610 may also 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 620 are disposed at equal intervals on the endless conveyor module and can move synchronously along the endless conveyor module. The plurality of transfer rollers 620 may also sequentially pass through the receiving position and the attaching position under the driving of the endless conveyor.

Further, when the transfer roller 620 cooperates with the bottom roller 120, the driving component 630 can drive the transfer roller 620 to revolve around the bottom roller 120; when the transfer roller 620 can be engaged with the first composite roller 300, the driving assembly 630 can drive the transfer roller 620 to revolve around the first composite roller 300.

In this embodiment, each driving assembly 630 includes a first driving member (not shown) and an arc rail 631, and each transfer roller 620 is mounted on the corresponding arc rail 631 and can slide along the arc rail 631 under the driving of the first driving member, and when the transfer roller 620 is matched with the bottom roller 120 or the first composite roller 300, the center of the arc rail 631 coincides with the center of the bottom roller 120 or the first composite roller 300, respectively.

The first driving member may be a servo motor. When the transfer roller 620 is located at the receiving position and abuts against the bottom roller 120, the first driving member drives the transfer roller 620 to slide along the arc rail 631, so that the transfer roller 620 can revolve around the bottom roller 120. Similarly, when the transfer roller 620 is located at the attaching position and abuts against the first composite roller 300, the first driving member drives the transfer roller 620 to slide along the arc-shaped rail 631, so that the transfer roller 620 can revolve around the first composite roller 300.

Specifically, the direction in which the transfer roller 620 revolves around the bottom roller 120 is opposite to the direction in which the bottom roller 120 rotates. As shown in fig. 12, the bottom roller 120 rotates clockwise, and the transfer roller 620 revolves counterclockwise around the bottom roller 120. When the transfer roller 620 is just engaged with the bottom roller 120, the transfer roller 620 is located at a position indicated by a dotted 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 620, the transfer roller 620 revolves to a solid line position shown in the figure, which is called a stock finishing position.

Since the transfer roller 620 is able to revolve around the bottom roller 120 during the process of capturing the CCM sheet 21 on the bottom roller 120, the time required for the transfer roller 620 to capture 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 620 is able to transfer the CCM sheet 21 to the lay-up position and simultaneously move the empty transfer roller 620 to the take-up position in preparation for the next CCM sheet 21 to be acquired. Moreover, the empty transfer roller 620 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.

Also, the first complex roll 300 rotates counterclockwise, and the transfer roll 620 revolves clockwise around the first complex roll 300. When the transfer roller 620 is just engaged with the first composite roller 300, the transfer roller 620 is located at a position indicated by a broken line in the drawing, which is referred to as an engagement start position; when the CCM sheet 21 on the transfer roller 620 is attached to the upper frame tape 30, the transfer roller 620 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 the bonding, the next region to be bonded (the region corresponding to the next first inner frame 301) of the upper frame 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 620 having the CCM sheet 21 adsorbed thereto enters the bonding position. Thus, by using the above time difference, the transfer and lamination mechanism 300 can continuously transfer the CCM sheet 21, so that the continuous tape running can be realized in the lamination process of the upper frame tape 30 and the CCM tape 20.

Moreover, no jump is present between the two CCM webs 21 from which the CCM web 20 is cut by the knife roll 110. However, the cut CCM sheet 21 is not immediately bonded to the upper frame tape 30, but is first transferred from the bonding position to the bonding position by the transfer roller 620. The upper rim strip 30 continues to run during the transfer of the CCM sheet 21. In this way, when the CCM sheets 21 are attached to the upper frame material belt 30, a jump distance is generated between two adjacent CCM sheets 21, so that the CCM sheets 21 can be sequentially attached to the first inner frames 301 of the upper frame material belt 30 at a plurality of intervals.

In this embodiment, when the transfer roller 620 is located at the receiving position, the driving assembly 630 can drive the transfer roller 620 to approach or separate from the bottom roller 120, so that the transfer roller 620 is engaged with or separated from the bottom roller 120; with the transfer roll 620 in the apply position, the drive assembly 630 can drive the transfer roll 620 toward or away from the first composite roll 300 to engage or disengage the transfer roll 620 from the first composite roll 300.

That is, the transfer roller 620 is not engaged with the bottom roller 120 and the first composite roller 300 as soon as it enters the receiving position and the attaching position, and a gap is generated between the transfer roller 620 and the bottom roller 120 and the first composite roller 300 after being separated from the bottom roller 120 and the first composite roller 300. In this way, the transfer assembly 610 can be facilitated to drive the plurality of transfer rollers 620 to move, so that interference is avoided.

It should be noted that in other embodiments, the position of the transfer roller 620 may be precisely adjusted, and the transfer roller 620, once in the receiving and bonding positions, may be engaged with the bottom roller 120 and the first composite roller 300, such that the drive assembly 630 is not required.

Further, in the present embodiment, a driven gear (not shown) is disposed on each of the transfer rollers 620, a first driving gear (not shown) is disposed on the bottom roller 120, and a second driving gear (not shown) is disposed on the first composite roller 300. Wherein, when the transfer roller 620 is matched with the bottom roller 120, the driven gear is meshed with the first driving gear; when the transfer roller 620 is engaged with the first complex roller 300, 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 620 and the bottom roller 120 can be achieved, and accordingly, inconsistent rotation speeds of the transfer roller 620 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 620 and the first composite roller 300 can be achieved, and accordingly, inconsistent rotation speeds of the transfer roller 620 and the composite roller in the attaching process are avoided.

In this embodiment, each driving assembly 630 further includes a linear guide rail 632 and a second driving member (not shown), and the arc-shaped guide rail 631 is mounted on the linear guide rail 632 and can move along the linear guide rail 632 under the driving of the second driving member.

When the transfer assembly 610 drives the transfer roller 620 to enter the receiving position, the second driving member drives the arc rail 631 to move along the linear rail 632, so as to drive the transfer roller 620 to approach or separate from the bottom roller 120, thereby enabling the transfer roller 620 to be engaged with or separated from the bottom roller 120. When the transfer assembly 610 drives the transfer roller 620 to enter the attaching position, the second driving member drives the arc rail 631 to move along the linear rail 632, so as to drive the transfer roller 620 to approach or separate from the first composite roller 300, thereby enabling the transfer roller 620 to be engaged with or separated from the first composite roller 300.

Further, in the present embodiment, each driving assembly 630 further includes a rotation driving member (not shown), and the rotation driving member drives the corresponding transfer roller 620 to rotate through a clutch (not shown), and the clutch is disengaged when the transfer roller 620 is engaged with the bottom roller 120 or the first composite roller 300.

Before the transfer roller 620 is matched with the bottom roller 120 and the first composite roller 300, the transfer roller 620 may rotate under the driving of the rotation driving member, so that the rotation speed of the transfer roller 620 is close to or equal to the rotation speeds of the first composite roller 300 and the bottom roller 120. In this way, at the moment when the transfer roller 620 is engaged with the bottom roller 120 or the first composite roller 300, slipping or the like due to an excessive difference in rotational speed between the transfer roller 620 and the first composite roller 300 or the bottom roller 120 can be prevented, thereby affecting material receiving and bonding. After the transfer roller 620 is engaged with the bottom roller 120 and the first composite roller 300, the clutch is disengaged, so that the rotation driving member is disengaged from the transfer roller 620, and the transfer roller 620 rotates along with the bottom roller 120 and the first composite roller 300.

Referring again to fig. 1, the first composite web 50 compounded at the first compounding roll 300 may be fed out through the rolls and around the second compounding roll 500. The lower frame strip 40 provided by the second framing mechanism 400 is also wound around the second composite roller 500. Thus, the first composite web 50 may be brought into roll-to-roll engagement with the lower edge web 40 at the second composite roll 500 to provide a second composite web 60. When the first composite material tape 50 and the lower frame material tape 40 are attached in a roll-to-roll manner, continuous tape feeding can be realized.

Therefore, in the process of forming the five-in-one material belt, the continuous belt feeding of the CCM material belt 20, the upper frame material belt 30 and the lower frame material belt 40 can be realized, so that the production efficiency of the fuel cell can be remarkably improved.

Before the first composite material strip 50 is attached to the lower frame material strip 40, the fourth CCD assembly is generally used to detect the alignment accuracy of the upper frame material strip 30 and the lower frame material strip 40, and only if the alignment accuracy meets the requirement, the attachment is performed. Otherwise, the beat of the second framing mechanism 400 will need to be adjusted.

Referring to fig. 13, in the embodiment, the five-in-one forming apparatus 10 further includes a stretching and cooling mechanism 800 and a winding mechanism 900, and the second composite material belt 60 can be wound around the stretching and cooling mechanism 800 and wound by the winding mechanism 900.

Specifically, the stretch cooling mechanism 800 includes a plurality of stretch straightening rollers 810 and a plurality of cooling rollers 820, and the stretch straightening rollers 810 and the cooling rollers 820 are both heating rollers. The second composite strip 60 can be wound around two stretch straightening rollers 810 in an S-shaped manner so that pull-up straightening is performed by the stretch straightening rollers 810. The second composite strip 60 then enters the chill roll 820 and the temperature of the plurality of chill rolls 820 gradually decreases in the direction of travel of the second composite strip 60, thereby allowing the second composite strip 60 to slowly cool to room temperature.

The structure and performance of the second composite material belt 60 processed by the stretching and cooling mechanism 800 tend to be stable, so the second composite material belt can be wound and stored by the winding mechanism 900. It should be appreciated that in other embodiments, the second composite strip 60 may be directly transported to the next station for the process of attaching the gas diffusion layer, without being wound.

Further, in the present embodiment, the winding mechanism 900 includes a composite tape receiving mechanism 910 and two winding shafts 920, and the second composite tape 60 can pass through the composite tape receiving mechanism 910 and be wound by any one of the winding shafts 920.

Both take-up reels 920 are capable of independently completing the take-up of the second composite web 60, and when one of the take-up reels 920 is full, it is possible to continue by the other take-up reel 920 and replace the full take-up reel 920 with an empty take-up reel 920. In this way, the continuity of the winding process can be ensured, so that the five-in-one forming device 10 can continuously operate.

In the above-mentioned five-in-one forming device 10, after the transfer roller 620 obtains the CCM sheet 21 on the bottom roller 120 at the receiving position, the CCM sheet 21 may be transferred to the bonding position to be bonded, and the obtained first composite material belt 50 is bonded to the lower frame material belt 40 at the second composite roller 500, so as to form the five-in-one material belt. Since the transfer roller 620 is able to revolve around the bottom roller 120 during the process of obtaining a CCM sheet 21, the time required for the transfer roller 620 to obtain one CCM sheet 21 will be less than one cutting cycle of the cutting mechanism 100. Likewise, the transfer roller 620 is able to revolve around the first composite roller 300 during the lamination process, so the time required to laminate one CCM sheet 21 will also be reduced. Within the resulting time difference, transfer roller 620 is able to transfer CCM sheet 21 to the bonding position and empty transfer roller 620 is moved to the receiving position in preparation for the next CCM sheet 21 acquisition. Thus, the upper frame material belt 30, the lower frame material belt 40 and the CCM material belt 20 can realize continuous tape running in the five-in-one material belt forming process, thereby remarkably improving the production efficiency of the fuel cell.
