[0002] In the preparation process of fuel cells, the alignment and bonding process of double-layer or triple-layer membrane materials is usually involved. For example, the five-in-one assembly is an intermediate product of MEA (membrane electrode), which is made of CCM double-sided bonding of cathode and anode frame membranes. Technical parameters such as the alignment of CCM and the double-sided bonding of the frame, the flatness of the bonding process, etc. have a great influence on the performance of the finished membrane electrode. As hydrogen fuel cells move towards industrial mass production, the size of membrane electrodes is getting larger and larger. However, due to the limitations of factors such as vacuum degree, the existing bonding device is prone to bubbles when bonding over a large area, which leads to a decrease in the potential density of the membrane electrode.

[0038] See also Figure 1 The utility model provides a membrane electrode laminating device 10 and a membrane material laminating device 100. The membrane electrode laminating device 10 comprises a membrane material laminating device 100, a frame 200 and a visual positioning device 300.

[0039] The frame 200 plays a supporting role and is generally formed by splicing metal rods and plates. The film material laminating device 10 and the visual positioning device 300 are both installed on the frame 200, and the visual positioning device 300 is located above the film material laminating device 10.

[0040] Please also read Figures 2 to 5 The film laminating device 100 in the preferred embodiment of the present invention includes a first adsorption mechanism 110 , a second adsorption mechanism 120 and a rolling mechanism 130 .

[0041] The first adsorption mechanism 110 includes a negative pressure cavity 111 and a mesh 112. The outline of the negative pressure cavity 111 can be cubic, cylindrical, etc., and has a cavity inside. The negative pressure device (not shown) can be connected to the negative pressure cavity 111, so as to form a negative pressure in the negative pressure cavity 111. One side of the negative pressure cavity 111 is open, and the mesh 112 covers the opening of the negative pressure cavity 111. The mesh 112 can be a mesh structure formed of resin, plastic or flexible metal, which can be expanded and contracted under the action of external force. Specifically, a frame (not marked in the figure) is provided along the periphery of the mesh 112, and the frame of the mesh 112 is connected to the opening edge of the negative pressure cavity 111, so that the mesh 112 covers the opening of the negative pressure cavity 111.

[0042] The mesh 112 can carry the first film material. For the bonding of the fuel cell, the first film material can be any one of the CCM sheets, the frame sheets, or a combination of the two. After the negative pressure is formed in the negative pressure cavity 110, the first film material carried on the mesh 112 can be adsorbed, so that the first film material can be effectively flattened on the surface of the mesh 112.

[0043] Please refer again Figure 4 In this embodiment, the first adsorption mechanism 110 also includes a quick caliper 113 , the net 112 is connected to the negative pressure chamber 111 via the quick caliper 113 , and the quick caliper 113 can adjust the horizontality of the net 112 .

[0044] Specifically, the quick caliper 113 includes two parts, one of which is mounted on the negative pressure chamber 111, and the other is mounted on the frame of the net 112. The two parts of the quick caliper 113 can be quickly disassembled and assembled, so as to facilitate the replacement of the net 112. Moreover, the relative position of the two parts of the quick caliper 113 can be adjusted, so as to adjust the horizontality of the net 112.

[0045] Furthermore, in the present embodiment, an elastic sealing ring 114 is sandwiched between the frame of the stretched net 112 and the end face of the opening of the negative pressure cavity 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 stretched net 112 and the negative pressure cavity 111, thereby preventing air from entering the negative pressure cavity 111 through the gap between the two and thus destroying the negative pressure environment. Moreover, when adjusting the horizontality of the stretched net 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 stretched net 112 and the negative pressure cavity 111, thereby ensuring the adjusted sealing performance, thereby ensuring the stability of the negative pressure in the negative pressure cavity 111, and being able to reliably adsorb the first film material.

[0046] 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 any one of the CCM sheet material and the frame sheet material or a combination of the two, and is different from the first film material.

[0047] 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 carried by the stretching net 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.

[0048] 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 stretching net 112. At this time, the second film material on the suction plate 122 and the first film material carried by the stretching net 112 can be stacked.

[0049] 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 .

[0050] 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.

[0051] 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.

[0052] 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 negative pressure cavity 111, and the pressing roller 131 can abut against the stretched net 112 under the drive of the lifting assembly 132, and can roll along the stretched net 112 under the drive of the translation assembly 133.

[0053] When the film materials need to be laminated, the first film material and the second film material to be laminated are first laid flat on the mesh 112 and the suction plate 122 and adsorbed, and then the flip assembly 121 drives the suction plate 122 to flip so that the second film material is laminated with the first film material. Then, the pressing roller 131 is driven by the lifting assembly 132 to abut against the mesh 112, thereby pressing the first film material and the second film material against the suction plate 122. As the translation assembly 133 drives the pressing roller 131 to roll along the mesh 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, thereby laminating the first film material and the second film material.

[0054] The following takes the preparation of a five-in-one component as an example to illustrate the working process of the film material laminating device 100:

[0055] First, the CCM sheet is laid flat on the stretching net 112, and the first layer of the frame sheet is laid flat on the suction plate 122; the suction plate 122 is turned 180 degrees under the drive of the turning assembly 121, so that the CCM sheet and the frame sheet are stacked; the lifting assembly 132 drives the pressing roller 131 to lift until the pressing roller 131 abuts against the CCM sheet and the frame sheet; under the drive of the translation assembly 133, the pressing roller 131 rolls from one side to the other side in close contact with the CCM sheet and the frame sheet, so that the CCM sheet and the frame sheet are attached to obtain a semi-finished product;

[0056] Next, the suction plate 122 returns to its original position under the drive of the flipping component 121, and the second layer of frame sheet material is spread flat on the suction plate 122; the semi-finished product carried on the stretching net 112 is turned over; the suction plate 122 is flipped 180 degrees again under the drive of the flipping component 121, so that the frame sheet material and the semi-finished product carried on the stretching net 112 are stacked; the lifting component 132 drives the pressure roller 131 to lift, and the translation component 133 drives the pressure roller 131 to roll from one side to the other side tightly against the semi-finished product and the frame sheet material, so that the semi-finished product and the second layer of frame sheet material are attached to obtain a five-in-one component; finally, the suction plate 122 returns to its original position under the drive of the flipping component 121.

[0057] 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.

[0058] When laminating the film materials, the visual positioning device 300 can obtain the image information of the first film material carried on the stretching net 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.

[0059] Please also read Figure 7 In this embodiment, the visual positioning device 300 includes a mounting rail 310, a camera module 320 and a locking handle 330. The mounting rail 310 is set on the frame 200, the camera module 320 can be slidably installed on the mounting rail 310, and the locking handle 330 can fix the camera module 320 on the mounting rail 310.

[0060] 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.

[0061] Also, please refer again to Figure 2 In 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 .

[0062] 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 stretched mesh 112.

[0063] Please refer again Figure 5 and Figure 6 In this embodiment, the roller pressing 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 activating the hot melt adhesive on the surface of the film material and ensuring the reliability of 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 negative pressure chamber 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 negative pressure chamber 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 stretched net 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] The above-mentioned film material laminating device 100 and membrane electrode laminating equipment 10 first lay the first film material and the second film material to be laminated on the stretching net 112 and the suction plate 122 respectively and adsorb them, and then the flip component 121 drives the suction plate 122 to flip so that the second film material is stacked with the first film material. Then, the pressure roller 131 is driven by the lifting component 132 to abut against the stretching net 112, so that the first film material and the second film material are pressed tightly against the suction plate 122. As the translation component 133 drives the pressure roller 131 to roll along the stretching net 112, the pressure 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 laminated. Since the pressure roller 131 gradually squeezes the first film material and the second film material from one side to the other side, the air between the first film material and the second film material can be squeezed out, thereby effectively avoiding the generation of bubbles.

[0071] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
