[0044] See also Figure 1 The membrane electrode processing equipment 10 in the preferred embodiment of the utility model includes a membrane material bonding device 100, a glue applying device 200, a visual positioning device 300, a glue erasing device 400 and a frame 500.
[0045] The frame 500 plays a supporting role and is generally formed by splicing metal rods and plates. The film laminating device 100 , the glue applying device 200 , the visual positioning device 300 and the glue erasing device 400 are all installed on the frame 500 , and the visual positioning device 300 is located above the film laminating device 10 .
[0046] Please also read Figures 2 to 5 The film laminating device 100 includes a first adsorption mechanism 110 , a second adsorption mechanism 120 and a rolling mechanism 130 .
[0047] The first adsorption mechanism 110 includes a base 111 and a flexible carrier 112. The flexible carrier 112 can be elastically deformed under the action of an external force, and can be a mesh structure or a porous sheet structure formed by an elastic material. The flexible carrier 112 can carry a first membrane material. For membrane electrode processing, the first membrane material can be a proton exchange membrane, a CCM sheet or a five-in-one component.
[0048] Specifically in this embodiment, the base 111 includes a negative pressure cavity with an opening on one side, and the flexible carrier 112 is configured as a stretched net covering the opening of the negative pressure cavity.
[0049] The base 111 may have a cubic or cylindrical profile, etc., and may have a cavity inside to form a negative pressure cavity. A negative pressure device (not shown) may be connected to the negative pressure cavity, thereby forming a negative pressure in the negative pressure cavity. The mesh may be a mesh structure formed of resin, plastic or flexible metal, and may be retracted under external force. Specifically, a frame (not shown) is provided along the periphery of the mesh, and the frame of the mesh is connected to the opening edge of the negative pressure cavity, so that the mesh covers the opening of the negative pressure cavity.
[0050] When negative pressure is formed in the negative pressure chamber, the first film material supported on the stretched net can be adsorbed, so that the first film material can be effectively flattened on the surface of the flexible support 112. Moreover, after being adsorbed, the first film material can maintain a stable position and shape, so that it is not easy to be misplaced or wrinkled during subsequent operations.
[0051] Please refer again Figure 4 In this embodiment, the first adsorption mechanism 110 further includes a quick clamp 113 , the flexible carrier 112 is connected to the base 111 via the quick clamp 113 , and the quick clamp 113 can adjust the horizontality of the flexible carrier 112 .
[0052] Specifically, the quick caliper 113 includes a two-part structure, one part of which is mounted on the base 111, and the other part is mounted on the frame of the flexible carrier 112. The two-part structure of the quick caliper 113 can be quickly disassembled and assembled, thereby facilitating the replacement of the flexible carrier 112. Moreover, the relative position of the two-part structure of the quick caliper 113 can be adjusted, thereby adjusting the horizontality of the flexible carrier 112.
[0053] Furthermore, in the present embodiment, an elastic sealing ring 114 is sandwiched between the frame of the flexible carrier 112 and the end face of the opening of the base 111. The elastic sealing ring 114 can be formed of a material with good ductility, such as foam. The elastic sealing ring 114 can achieve sealing at the junction of the flexible carrier 112 and the base 111, thereby preventing air from entering the negative pressure cavity through the gap between the two and thus destroying the negative pressure environment. Moreover, when adjusting the horizontality of the flexible carrier 112, since the elastic sealing ring 114 is ductile, the elastic sealing ring 114 can automatically adapt to the shape of the gap between the flexible carrier 112 and the base 111, thereby ensuring the adjusted sealing performance, thereby ensuring the stability of the negative pressure in the negative pressure cavity, and being able to reliably adsorb the first film material.
[0054] Please refer again Figure 2 and Figure 3 The second adsorption mechanism 120 includes a flip assembly 121 and a suction plate 122. The suction plate 122 can adsorb the second film material so that the second film material can be effectively flattened on the surface of the suction plate 122. The suction plate 122 can adsorb the second film material by vacuum adsorption, electrostatic adsorption, etc. For the bonding of the fuel cell, the second film material can be a catalyst transfer film, a frame sheet or a gas diffusion layer sheet.
[0055] Furthermore, the flip assembly 121 can drive the suction plate 122 to flip, so that the second film material adsorbed on the suction plate 122 is stacked with the first film material supported by the flexible support 112. Specifically, the flip assembly 121 generally includes a flip motor and a worm gear reducer. The worm gear reducer can drive the suction plate 122 to flip through a belt. The worm gear reducer has a self-locking function, so the limiting structure for limiting the suction plate 122 can be omitted, thereby simplifying the overall structure.
[0056] In the initial state, the flip assembly 121 can drive the suction plate 122 to flip to the suction surface facing upward, so as to facilitate the placement of the second film material; during the laminating process, the flip assembly 121 can drive the suction plate 122 to flip 180 degrees until the suction surface is roughly parallel to and close to the flexible carrier 112. At this time, the second film material of the suction plate 122 and the first film material carried by the flexible carrier 112 can be stacked.
[0057] In this embodiment, the second adsorption mechanism 120 further includes a support frame 123 , the suction plate 122 is rotatably mounted on the support frame 123 via a rotation shaft 124 , and the flip assembly 121 is disposed in the support frame 123 and is transmission-connected to the rotation shaft 124 .
[0058] The support frame 123 can be formed by splicing metal rods, and a receiving space is formed inside the support frame 123. The flip assembly 121 is arranged in the support frame 123, so that the space can be reasonably utilized, thereby helping to reduce the overall size of the device.
[0059] Further, in this embodiment, the support frame 123 is provided with a bent plate 1231 bent toward the first adsorption mechanism 110, and the rotation shaft 124 is provided on the bent plate 1231. In this way, the distance between the suction plate 122 and the first adsorption mechanism 110 can be effectively shortened, thereby helping to reduce the overall size of the device.
[0060] Please also read Figure 5 and Figure 6 The rolling mechanism 130 includes a pressing roller 131, a lifting assembly 132 and a translation assembly 133. The pressing roller 131 is received in the base 111, and the pressing roller 131 can abut against the flexible carrier 112 under the drive of the lifting assembly 132, and can roll along the flexible carrier 112 under the drive of the translation assembly 133.
[0061] The film material laminating device 100 can achieve laminating of the first film material and the second film material. First, the first film material and the second film material to be laminar are laid flat on the flexible carrier 112 and the suction plate 122 respectively and adsorbed, and then the flip assembly 121 drives the suction plate 122 to flip, so that the second film material and the first film material are stacked. Then, the pressing roller 131 is driven by the lifting assembly 132 to abut against the flexible carrier 112, so that the first film material and the second film material are pressed against the suction plate 122. As the translation assembly 133 drives the pressing roller 131 to roll along the flexible carrier 112, the pressing roller 131 can be closely attached to the first film material and the second film material and rolled from one side to the other side, so that the first film material and the second film material are laminar.
[0062] The pressure roller 131 can be a rubber-coated roller to reduce wear on the film material. Since the pressure roller 131 can gradually squeeze from one side to the other side during the lamination process, the air between the frame sheet and the CCM sheet can be squeezed out, thereby effectively avoiding the generation of bubbles in the obtained five-in-one assembly.
[0063] In this embodiment, the rolling mechanism 130 further includes a heating rod 134, which is embedded in the pressing roller 131 and can heat the pressing roller 131. The heating rod 134 can increase the temperature of the surface of the pressing roller 131, so that the film material can be heated during the lamination process, thereby improving the lamination effect to ensure the reliability of the lamination.
[0064] Furthermore, in this embodiment, the rolling mechanism 130 further includes a conductive slip ring 135 coaxially arranged with the pressing roller 131, and one end of the conductive slip ring 135 is electrically connected to the heating rod 134. The heating rod 134 is generally energized to generate heat, and one end of the conductive slip ring 135 away from the heating rod 134 can be connected to a power source, thereby connecting the heating rod 134 to the power source. Therefore, the conductive slip ring 135 can ensure that there is no wire winding during the rolling process of the pressing roller 131.
[0065] In this embodiment, the rolling mechanism 130 also includes a base 136 and a lifting frame 137. The base 136 can be slidably installed in the base 111 and can slide under the drive of the translation component 133. The lifting frame 137 can be slidably installed on the base 136 and can be lifted and lowered relative to the base 136 under the drive of the jacking component 132. The pressure roller 131 is installed on the lifting frame 137.
[0066] The base 136 can be installed in the base 111 through a guide rail, and the lifting frame 137 can be connected to the base 136 through a linear bearing. When the lifting assembly 132 drives the lifting frame 137 to rise and fall relative to the base 136, the pressure roller 131 can be driven to rise and fall. When the translation assembly 133 drives the base 136 to slide, the pressure roller 131 can be driven to roll along the flexible bearing 112. Specifically, the lifting assembly 132 can be a cylinder. The translation assembly 133 can be a screw pair structure composed of a motor and a screw.
[0067] In this embodiment, the rolling mechanism 130 also includes a rolling support 138 and an adjusting shaft 139. The rolling roller 131 is rotatably mounted on the rolling support 138. The adjusting shaft 139 is perpendicular to the rotation axis of the rolling roller 131. The rolling support 138 is rotatably mounted on the lifting frame 137 through the adjusting shaft 139.
[0068] During the lamination process of the pressing roller 131, the pressing roller bracket 138 can rotate around the adjustment shaft 139, thereby driving the pressing roller 131 to swing left and right. In this way, the pressing roller 131 can automatically adapt to the plane of the suction plate 122 during the lamination process, thereby always keeping close contact with the film material, further reducing the risk of generating bubbles.
[0069] Furthermore, in this embodiment, the lifting frame 137 is provided with limit blocks 1371, which are distributed on both sides of the adjustment shaft 139, and the pressure roller bracket 138 can rotate around the adjustment shaft 139 until it abuts against the limit blocks 1371. The limit blocks 1371 can limit the rotation range of the pressure roller bracket 138, thereby preventing the pressure roller bracket 138 from rotating too much and causing the pressure roller 131 to be unable to abut against the film material.
[0070] When laminating the film materials, the visual positioning device 300 can obtain the image information of the first film material carried on the flexible carrier 112. By comparing and analyzing the image information of the first film material, it can be determined whether there is a deviation in the position of the first film material. Therefore, when there is a deviation in the position of the first film material, the first film material can be adjusted to ensure the alignment of the first film material and the second film material after laminating.
[0071] Please also read Figure 8 In this embodiment, the visual positioning device 300 includes a mounting rail 310, a camera module 320 and a locking handle 330. The camera module 320 can be slidably mounted on the mounting rail 310, and the locking handle 330 can fix the camera module 320 on the mounting rail 310.
[0072] Specifically, the mounting rail 310 is provided on the frame 500, and the camera module 320 is used to collect image information of the first film material. When the locking handle 330 is in the unlocked state, it can drive the camera module 320 to slide along the mounting rail 310, thereby switching the position of the camera module 320. When the position of the camera module 320 is adjusted to the right position, the locking handle 330 can be switched to the locked state to fix the camera module 320 on the mounting rail 310. It can be seen that the mounting rail 310 and the locking handle 330 can cooperate to quickly adjust the position of the camera module 320, so it is convenient for product conversion to be compatible with first film materials of different sizes.
[0073] Also, please refer again to Figure 2In this embodiment, the film laminating device 100 further includes a deviation correcting mechanism 140 , and the first adsorption mechanism 110 is disposed on the deviation correcting mechanism 140 .
[0074] The deflection correction mechanism 140 can drive the first adsorption mechanism 110 to move in multiple degrees of freedom, thereby adjusting the position of the first film material. Therefore, when there is a deviation in the position of the first film material, the position of the first film material can be corrected by the deflection correction mechanism 140. Specifically, the deflection correction mechanism 140 can drive the first adsorption mechanism 110 to translate in two directions perpendicular to each other, and can drive the first adsorption mechanism 110 to rotate around an axis perpendicular to the surface of the flexible carrier 112.
[0075] Based on this, the membrane electrode processing equipment 10 can realize the preparation of CCM components. Among them, the first membrane material is a proton exchange membrane, and the second membrane material is an anode catalyst transfer membrane or a cathode catalyst transfer membrane. The general process is as follows:
[0076] First, the proton exchange membrane is laid flat on the flexible carrier 112, and the anode catalyst transfer membrane is laid flat on the suction plate 122; the suction plate 122 is turned 180 degrees under the drive of the flip assembly 121, so that the anode catalyst transfer membrane and the proton exchange membrane are stacked; the lifting assembly 132 drives the pressure roller 131 to lift until the pressure roller 131 abuts against the flexible carrier 112 and holds the proton exchange membrane and the anode catalyst transfer membrane against the suction plate 122; under the drive of the translation assembly 133, the pressure roller 131 rolls from one side to the other side in close contact with the stacked proton exchange membrane and the anode catalyst transfer membrane, so that the anode catalyst layer on the anode catalyst transfer membrane is transferred to the surface of the proton exchange membrane and a CCM semi-finished product is obtained;
[0077] Next, the suction plate 122 returns to its original position under the drive of the flipping component 121, and the cathode catalyst transfer membrane is spread flat on the suction plate 122; the CCM semi-finished product carried on the flexible carrier 112 is turned over; the suction plate 122 is flipped 180 degrees again under the drive of the flipping component 121, so that the cathode catalyst transfer membrane and the CCM semi-finished product carried on the flexible carrier 112 are stacked; the rolling mechanism 130 is activated again, and the cathode catalyst layer on the cathode catalyst transfer membrane can be transferred to the other surface of the proton exchange membrane to obtain a CCM component.
[0078] Please also read Figure 7 The glue applying device 200 includes a driving mechanism 210 and a glue applying head 220. The glue applying head 220 can be moved above the suction plate 122 under the drive of the driving mechanism 210, and apply glue to the surface of the second film material carried by the suction plate 122 along a preset trajectory.
[0079] The adhesive head 220 is connected to the adhesive storage container, and the adhesive discharge control can be realized through components such as electromagnetic valves. The driving mechanism 210 can adopt a multi-degree-of-freedom robotic arm, or a servo mechanism that can move in three directions of the X-axis, Y-axis and Z-axis. The adhesive head 220 is arranged at the driving end of the driving mechanism 210, and the driving mechanism 210 can move the adhesive head 220 to a desired position.
[0080] Based on this, the membrane electrode processing equipment 10 can also complete a five-in-one process. Among them, the first membrane material is a CCM component, and the second membrane material is an anode frame or a cathode frame. The general process is as follows:
[0081] First, lay the CCM component flat on the flexible carrier 112, and lay the anode frame flat on the suction plate 122; the glue spreading head 220 moves to the top of the anode frame under the drive of the driving mechanism 210, and spreads glue on the surface of the anode frame along the preset trajectory; the suction plate 122 flips 180 degrees under the drive of the flipping component 121, so that the anode frame and the CCM component are stacked; the lifting component 132 drives the pressure roller 131 to lift until the pressure roller 131 abuts against the flexible carrier 112 and holds the CCM component and the anode frame against the suction plate 122; under the drive of the translation component 133, the pressure roller 131 rolls from one side to the other side in close contact with the CCM component and the anode frame, so that the CCM component and the anode frame are attached to each other and a five-in-one semi-finished product is obtained;
[0082] Next, the suction plate 122 returns to its original position under the drive of the flipping component 121, and the cathode frame is laid flat on the suction plate 122; the glue applying device 200 applies glue on the surface of the cathode frame in the same way; the five-in-one semi-finished product carried on the flexible carrier 112 is turned over; the suction plate 122 is flipped 180 degrees again under the drive of the flipping component 121, so that the cathode frame is stacked with the five-in-one semi-finished product carried on the flexible carrier 112; the rolling mechanism 130 is activated again, so that the cathode frame can be attached to the other side of the CCM component to obtain a five-in-one component.
[0083] In addition, the membrane electrode processing equipment 10 can also complete a seven-in-one process. The first membrane material is a five-in-one component, and the second membrane material is an anode gas diffusion layer or a cathode gas diffusion layer. The general process is as follows:
[0084] First, the five-in-one component is laid flat on the flexible carrier 112, and the anode gas diffusion layer is laid flat on the suction plate 122; the glue spreading head 220 is driven by the driving mechanism 210 to move above the anode gas diffusion layer, and spreads glue on the surface of the anode gas diffusion layer along a preset track; the suction plate 122 is turned 180 degrees under the drive of the flip component 121, so that the anode gas diffusion layer and the five-in-one are overlapped; the lifting component 132 drives the pressure roller 131 to lift until the pressure roller 131 abuts against the flexible carrier 112 and holds the five-in-one component and the anode gas diffusion layer against the suction plate 122; driven by the translation component 133, the pressure roller 131 is pressed against the five-in-one component C and the anode gas diffusion layer from one side to the other, so that the five-in-one component and the anode gas diffusion layer are attached to each other and a seven-in-one semi-finished product is obtained;
[0085] Next, the suction plate 122 returns to its original position under the drive of the flipping assembly 121, and the cathode gas diffusion layer is laid flat on the suction plate 122; the glue applying device 200 applies glue on the surface of the cathode gas diffusion layer in the same way; the seven-in-one semi-finished product carried on the flexible carrier 112 is turned over; the suction plate 122 is flipped 180 degrees again under the drive of the flipping assembly 121, so that the cathode gas diffusion layer is stacked with the seven-in-one semi-finished product carried on the flexible carrier 112; the rolling mechanism 130 is activated again, so that the cathode gas diffusion layer can be bonded to the other side of the five-in-one assembly to obtain a membrane electrode.
[0086] It can be seen that by placing different types of membrane materials on the flexible carrier 112 and the suction plate 122, the above-mentioned membrane electrode processing equipment 10 can realize catalyst coating, five-in-one and seven-in-one, so it can reduce the number of equipment required in the membrane electrode processing process, thereby reducing production costs.
[0087] In this embodiment, the glue application device 200 further includes a plasma nozzle 230 . The plasma nozzle 230 can be moved above the suction plate 122 under the drive of the driving mechanism 210 , and perform plasma treatment on the second film material supporting the suction plate 122 along a preset trajectory.
[0088] Specifically, since the surface of the frame is smooth and not easy to be adhered to by glue, before the glue applying head 220 applies glue to the surface of the anode frame and the cathode frame, the plasma nozzle 230 can first perform plasma treatment on the surface of the anode frame and the cathode frame where glue is to be applied, so as to increase the roughness of the surface and improve the adhesion of glue. Since the gas diffusion layer is porous and has an uneven surface, it is easy to be adhered to by glue, so in the seven-in-one process, it is generally not necessary to perform plasma treatment on the anode gas diffusion layer and the cathode gas diffusion layer.
[0089] In addition, in this embodiment, the adhesive head 220 can be moved to the working area of the adhesive wiping device 400 under the drive of the driving mechanism 210, and the adhesive wiping device 400 can perform a wiping action on the adhesive head 220 that enters the working area. The adhesive wiping device 400 can remove the residual glue from the adhesive head 200, thereby preventing the residual glue from drying and clogging the adhesive head 200 or causing unstable adhesive discharge.
[0090] Obviously, when the glue applying device 200 is provided with a blowing and sucking component for cleaning residual glue, the glue erasing device 400 can also be omitted.
[0091] Please also read Fig. 9 In this embodiment, the erasing device 400 includes a reeling mechanism 410, a reeling mechanism 420 and an erasing head 430. The reeling mechanism 410 is used to unwind the erasing tape, and the reeling mechanism 420 is used to reel in the erasing tape unwound by the reeling mechanism 410. The erasing tape between the reeling mechanism 410 and the reeling mechanism 420 is wound around the erasing head 430. The erasing head 430 is used to abut against the cloth rubber head 220 entering the working area.
[0092] Specifically, the winding mechanism 420 can be in the form of a winding motor and a material shaft, and the winding motor drives the material shaft to rotate so that the wiping tape can be wound on the material shaft. When cleaning the cloth rubber head 220, the wiping head 430 abuts against the cloth rubber head 220, and the wiping tape passes through the wiping head 430 in sequence under the traction of the winding mechanism 420 and is abutted against the cloth rubber head 220 by the wiping head 430. In this way, the moving wiping tape can wipe the cloth rubber head 220, thereby cleaning the residual glue on the cloth rubber head 220. In addition, the residual glue will be absorbed by the wiping tape, thereby avoiding glue dripping and contamination of other components.
[0093] The membrane electrode processing equipment 10 can first place the proton exchange membrane and the catalyst transfer membrane on the flexible carrier 112 and the suction plate 122 respectively; then the flip assembly 121 drives the suction plate 122 to flip until the catalyst transfer membrane and the proton exchange membrane are stacked; the rolling mechanism 130 can roll the catalyst to the proton exchange membrane layer; then the proton exchange membrane is turned over, and the catalyst transfer can be completed on the other side in the same way to obtain the CCM component. Next, the CCM component is placed on the flexible carrier 112, the frame is placed on the suction plate 122, and the glue-applying device 200 spreads glue on its surface. In the same way, the frame can be attached to both sides of the CCM component to obtain a five-in-one component. Finally, the five-in-one component is placed on the flexible carrier 112, the gas diffusion layer is placed on the suction plate 122, and the glue-applying device 200 spreads glue on its surface. In the same way, the gas diffusion layer can be attached to both sides of the five-in-one component and the preparation of the membrane electrode can be completed. It can be seen that catalyst coating, five-in-one and seven-in-one can all be completed by the above-mentioned membrane electrode processing equipment 10, so the number of equipment can be reduced to reduce production costs.
