DETAILED DESCRIPTION

[0051] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0052] In the present application, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inner", "outer", "vertical", "horizontal", "lateral", "longitudinal" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings. These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0053] In addition, some of the above terms may be used to express other meanings in addition to indicating orientation or positional relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to specific circumstances.

[0054] In addition, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0055] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0056] In the production of fuel cells and electrolyzers, the precise stacking of membrane electrodes, bipolar plates and gas diffusion layers is an important process. Traditional stacking methods rely on manipulators to use suction cups to grab and transfer these materials piece by piece. However, due to the different physical properties of these materials, such as hardness, weight, permeability and surface properties, traditional adsorption and transfer methods are not applicable.

[0057] The membrane electrode is the core material among the above materials, and is usually made of soft materials such as PEN (polyethylene naphthalate), PI (polyimide) or PEEK (polyetheretherketone). This causes the membrane electrode to shrink and deform easily and the catalyst layer to be damaged when it is sucked by a traditional suction cup, resulting in the destruction of the flatness of the membrane electrode and the integrity of the catalyst layer.

[0058] As a conductive and supporting structure, bipolar plates are usually made of metal plates with high quality and density. In addition, the central area of ​​the bipolar plate is also designed with a complex flow channel structure, which makes the surface flatness of the bipolar plate not high. When using traditional suction cups for adsorption, it is easy to leak, resulting in weak adsorption, and even falling during transportation, causing production accidents.

[0059] As a gas transmission channel in fuel cells and electrolyzers, the gas diffusion layer is usually made of porous media materials such as titanium felt and carbon fiber woven cloth. The gas diffusion layer has good air permeability and conductivity, but its air permeability is different from that of the membrane electrode. When using traditional suction cups for adsorption, the negative pressure generated by the traditional suction cups cannot form an effective seal due to the porous medium of the gas diffusion layer, resulting in weak adsorption or no adsorption.

[0060] Based on the above situation, an embodiment of the present application provides an adsorption component to adsorb and transport materials with different physical properties and surface properties such as membrane electrodes, bipolar plates and gas diffusion layers, thereby improving the production efficiency of the battery and the reliability of material transportation.

[0061] like Figures 1 to 4 The figure shows a schematic diagram of the structure of an adsorption component 100, which includes: a first suction cup 10, the first suction cup 10 includes a porous adsorption surface 101, and a plurality of adsorption holes 102 are arranged on the porous adsorption surface 101; a second suction cup 20, installed on the first suction cup 10, the second suction cup 20 includes a sponge adsorption surface 201; a third suction cup 30, installed on the first suction cup 10, the third suction cup 30 includes a non-contact adsorption surface 301, and the non-contact adsorption surface 301, the sponge adsorption surface 201 and the porous adsorption surface 101 are arranged to avoid each other; wherein, the adsorption directions of the porous adsorption surface 101, the sponge adsorption surface 201 and the non-contact adsorption surface 301 are the same.

[0062] like Figure 2 As shown, the first suction cup 10 includes a porous adsorption surface 101, and the porous adsorption surface 101 includes a plurality of adsorption holes 102. When the plurality of adsorption holes 102 are connected to a vacuum generator, they can form a plurality of vacuum cavities based on the Coanda effect between the material to be adsorbed having a flat and sealed surface, thereby stably adsorbing the material to be adsorbed. Therefore, the first suction cup 10 is suitable for adsorbing membrane electrodes having relatively flat and sealed surface characteristics. Of course, the first suction cup 10 can also be used to adsorb other materials to be adsorbed having flat and sealed surfaces.

[0063] Specifically, the first suction cup 10 can be constructed in a flat plate shape, and the first suction cup 10 is usually close to the contour of the membrane electrode to be sucked, so as to stably suck the membrane electrode. In addition, since the flat first suction cup 10 has no protruding foreign matter on the surface, it can avoid damaging the thin-film membrane electrode and the catalyst layer attached to the membrane electrode, so as to ensure the flatness of the membrane electrode and the integrity of the catalyst layer during the sucking process.

[0064] like Figure 2 As shown, a plurality of adsorption holes 102 can be evenly distributed on the porous adsorption surface 101, so that the adsorption force distribution of the entire porous adsorption surface 101 can be more even. Optionally, each adsorption hole 102 can have the same structure and size. In this way, when the first suction cup 10 contacts the membrane electrode, a plurality of independent vacuum cavities formed between the porous adsorption surface 101 and the membrane electrode based on the Coanda effect can be evenly distributed on the porous adsorption surface 101, thereby avoiding local deformation of the membrane electrode due to excessive force at a single point, and effectively preventing the membrane electrode from drooping or twisting during the process of being sucked by the porous adsorption surface 101.

[0065] The second suction cup 20 includes a sponge adsorption surface 201. The second suction cup 20 is connected to the vacuum generator. When the vacuum generator is working, negative pressure will be formed in the sponge adsorption surface 201. Since the sponge suction cup surface is resistant to high temperature, soft and has good resilience, the second suction cup 20 can fully contact the uneven surface to improve the vacuum sealing between the sponge adsorption surface 201 and the material to be adsorbed. Therefore, the second suction cup 20 is suitable for sucking bipolar plates with flow channels on the surface and low surface flatness. Of course, the second suction cup 20 can also be used to absorb other heavier materials.

[0066] When the second suction cup 20 absorbs the bipolar plate, the sponge absorption surface 201 will directly contact the surface of the bipolar plate. On the one hand, the sponge absorption surface 201 is soft and will not damage the surface of the bipolar plate; on the other hand, the sponge absorption surface 201 has elastic deformation ability when squeezed, so that the sponge absorption surface 201 can fit tightly to the surface of the bipolar plate. Therefore, even if the bipolar plate is heavy and the surface is uneven, the second suction cup 20 with the sponge absorption surface 201 can still achieve an efficient and reliable absorption effect on the bipolar plate because it can tightly absorb the bipolar plate.

[0067] The third suction cup 30 has a non-contact adsorption surface 301. When the third suction cup 30 is connected to the air compressor, the air compressor can provide sufficient airflow and pressure to ensure that the non-contact adsorption surface 301 can form a pressure difference with the surface of the material to be adsorbed. Since there is a positive pressure area on the non-contact adsorption surface 301, the gas molecules in the positive pressure area push the material to be adsorbed to the non-contact adsorption surface 301 of the third suction cup 30 under the action of the pressure difference. In the above-mentioned adsorption process, it is the flow and pressure difference of the gas molecules that produce the adsorption effect, and the adsorption does not depend on the sealing or flat surface of the material to be adsorbed. Therefore, the third suction cup 30 is suitable for adsorbing the gas diffusion layer. Of course, the third suction cup 30 can also be used to adsorb other materials with sealed surfaces or non-sealed surfaces. Optionally, the gas diffusion layer can be titanium felt, carbon fiber woven cloth or carbon cloth, etc.

[0068] The non-contact adsorption surface 301 of the third suction cup 30 can form a pressure difference with the surface of the gas diffusion layer, so that the gas diffusion layer is stably adsorbed on the third suction cup 30 without direct contact with the non-contact adsorption surface 301, and damage or scratches on the surface of the gas diffusion layer caused by contact are avoided, while ensuring the stability and reliability of the adsorption of the gas diffusion layer.

[0069] like Figure 1 , Figure 3 and Figure 4As shown, in order to combine the second suction cup 20 and the third suction cup 30 with the first suction cup 10 into a group of adsorption components 100, the second suction cup 20 and the third suction cup 30 can both be set on the first suction cup 10, thereby forming a multifunctional adsorption component 100 with the first suction cup 10 that can adsorb different materials to be adsorbed.

[0070] Exemplarily, the side of the first suction cup 10 facing away from the porous adsorption surface 101 may include a plate with load-bearing capacity, and the second suction cup 20 and the third suction cup 30 may be arranged on the plate with load-bearing capacity. The first suction cup 10 thereby realizes structural support for the second suction cup 20 and the third suction cup 30 and is integrated into a multifunctional adsorption component 100.

[0071] Furthermore, if Figure 2 , Figure 3 and Figure 4 As shown, the porous adsorption surface 101, the sponge adsorption surface 201 and the non-contact adsorption surface 301 have the same adsorption direction and avoid each other, so that the first suction cup 10, the second suction cup 20 and the third suction cup 30 can simultaneously face the stacked membrane electrode, the bipolar plate and the gas diffusion layer when performing the adsorption operation, without the need to readjust the direction of the adsorption component when adsorbing different materials.

[0072] In addition, since the relative positions of the porous adsorption surface 101, the sponge adsorption surface 201 and the non-contact adsorption surface 301 are fixed, the adsorption component 100 can also ensure the stability and positioning accuracy of the material during the transmission, positioning and assembly process.

[0073] Thus, in the adsorption assembly 100 provided in the embodiment of the present application, the porous adsorption surface 101 of the first suction cup 10 generates multiple independent vacuum adsorption cavities between the membrane electrode based on the Coanda effect, and the multiple independent vacuum cavities can stably and evenly absorb the membrane electrode; the sponge adsorption surface 201 of the second suction cup 20 can be closely attached to the bipolar plate with a low surface flatness to ensure the adsorption reliability of the bipolar plate; the non-contact adsorption surface 301 of the third suction cup 30 can stably absorb the gas diffusion layer with porous medium. The adsorption assembly 100 integrating the first suction cup 10, the second suction cup 20 and the third suction cup 30 can take into account the adsorption of different materials, so that the adsorption assembly 100 can absorb the membrane electrode, bipolar plate or gas diffusion layer as needed, without the need to switch the suction cup, thereby improving the rhythm of material handling, thereby effectively improving the processing efficiency of the fuel cell or electrolyzer.

[0074] Furthermore, the third suction cup 30 is a Bernoulli suction cup, which is a suction cup utilizing the Bernoulli effect. The Bernoulli suction cup utilizes the local increase in the velocity of the airflow flowing out of the suction cup to maintain the absorption of the material to be absorbed in a non-contact absorption manner.

[0075] Specifically, in the Bernoulli effect, the pressure of the airflow decreases as the flow rate increases. When the high-pressure air passes through the hole structure inside the Bernoulli suction cup, the airflow rate increases rapidly at the outlet of the Bernoulli suction cup, thereby forming a local low-pressure area around the suction cup, thereby generating a pressure difference relative to the surrounding environment, so that the Bernoulli suction cup can adsorb the material to be adsorbed. Therefore, by controlling the flow rate (flow rate, pressure) of the fluid ejected from the third suction cup 30, it is possible to maintain a stable adsorption state of the gas diffusion layer.

[0076] In some embodiments, Figure 5 As shown, the first suction cup 10 includes a cover plate 103 and an adsorption plate 104 which are arranged opposite to each other and interlocked along a first direction, and the cover plate 103 and the adsorption plate 104 enclose a cavity. The first direction can be a plumb bob direction, or a height direction of the adsorption assembly 100, or a stacking direction of the material to be adsorbed.

[0077] like Figure 6 As shown, the cover plate 103 is a metal cover plate 103 with bearing capacity, and the cover plate 103 may be provided with openings, grooves or channels, etc., so that the second suction cup 20 and the third suction cup 30 can be installed on the cover plate 103. The cover plate 103 is also provided with a plurality of first ventilation joints 108, each of which is used to connect to a vacuum generator, and the plurality of first ventilation joints 108 may be evenly distributed on the cover plate 103 to ensure balanced airflow.

[0078] Each first vent connector 108 includes a positive pressure vent and a negative pressure vent. When the negative pressure vent is ventilated, the first suction cup 10 can generate a negative pressure vacuum suction force to adsorb the membrane electrode. When the positive pressure vent is ventilated, the first suction cup 10 can quickly release the membrane electrode tightly adsorbed on the porous adsorption surface 101 to improve the handling cycle.

[0079] The cover plate 103 and the adsorption plate 104 are arranged along a first direction and interlocked with each other. The adsorption plate 104 includes a porous adsorption surface 101 for adsorption with the membrane electrode. A plurality of adsorption holes 102 penetrate the adsorption plate 104 and communicate with the cavity.

[0080] Thus, when the vacuum generator is working, since the cavity is connected to the vacuum generator, the multiple adsorption holes 102 connected to the cavity allow the air around the adsorption plate 104 to be extracted. When the membrane electrode contacts the porous adsorption surface 101, based on the Coanda effect, the airflow is accelerated around the adsorption holes 102 of the porous adsorption surface 101, so that an independent vacuum cavity is formed between each adsorption hole 102 and the membrane electrode, and the multiple adsorption holes 102 also form multiple vacuum cavities, so that the adsorption plate 104 generates a stable adsorption force. This adsorption force can not only make the membrane electrode fit flatly on the first suction cup 10 to prevent the membrane electrode from drooping, but also maintain stability during the transportation of the membrane electrode.

[0081] In some embodiments, Figure 5 and Figure 6 As shown, the first suction cup 10 also includes a first avoidance channel 105 extending in the first direction, that is, the first avoidance channel 105 extends through the cover plate 103 and the adsorption plate 104, and the first avoidance channel 105 is not connected to the cavity. The second suction cup 20 is arranged on the cover plate 103, and the cross-sectional area of ​​the first avoidance channel 105 is adapted to the shape of the second suction cup 20 to place the second suction cup 20, and the sponge adsorption surface 201 of the second suction cup 20 and the porous adsorption surface 101 of the first suction cup 10 form mutual avoidance.

[0082] The first avoidance channel 105 is located in the central area of ​​the first suction cup 10, that is, the second suction cup 20 is arranged in the central area of ​​the entire adsorption assembly 100, so that the second suction cup 20 can correspond to the central area of ​​the bipolar plate, and the central area of ​​the bipolar plate has more flow channels, and the sponge adsorption surface 201 of the second suction cup 20 can fit tightly to the surface of the bipolar plate with the flow channels, thereby stably adsorbing the central area of ​​the bipolar plate.

[0083] Please refer to Figure 1 The second suction cup 20 includes a suction cup body, which includes a substrate 202 on a side away from the sponge adsorption surface 201. The substrate 202 is provided with a second ventilation interface connected to the vacuum generator. Each second ventilation connector 203 includes a positive pressure vent and a negative pressure vent. When the negative pressure vent is ventilated, the second suction cup 20 can generate a negative pressure vacuum adsorption force to adsorb the bipolar plate. When the positive pressure vent is ventilated, the second suction cup 20 can quickly release the bipolar plate tightly adsorbed on the sponge adsorption surface 201 to improve the handling rhythm.

[0084] Since the bipolar plate is heavy, in order to ensure reliable adsorption of the bipolar plate, a plurality of second suction cups 20 may be provided on the cover plate 103 of the first suction cup 10 to improve the reliability of the adsorption assembly 100 in adsorbing the bipolar plate.

[0085] Specifically, some of the multiple second suction cups 20 can be arranged on the surrounding side of the first suction cup 10. This not only ensures that the distribution of the second suction cups 20 is relatively balanced, but also because the sponge adsorption surface 201 of the second suction cup 20 avoids the porous adsorption surface 101 of the first suction cup 10, arranging the second suction cup 20 on the surrounding side of the first suction cup 10 will not affect the adsorption area of ​​the first suction cup 10, while taking into account the adsorption reliability of the adsorption assembly 100 on the membrane electrode and the bipolar plate.

[0086] For further information, please refer to Figure 1 and Figure 2At least two second suction cups 20 among the multiple second suction cups 20 are located on two opposite sides of the first suction cup 10 along the second direction. The second direction is perpendicular to the first direction, that is, the second direction is located in a horizontal plane. The second direction can be the width direction of the first suction cup 10 or the length direction of the first suction cup 10.

[0087] In this way, at least two second suction cups 20 are arranged on both sides of the first suction cup 10, so that the two second suction cups 20 correspond to the length direction or width direction of the bipolar plate, thereby ensuring that the second suction cups 20 can adsorb the bipolar plate more balanced and stably, and prevent the bipolar plate from drooping on both sides during transportation.

[0088] It should be noted that one of the plurality of second suction cups 20 may be disposed in the first avoidance channel 105 at the center of the first suction cup 10, and the remaining plurality of second suction cups 20 may be located on the periphery of the first suction cup 10, so that the adsorption force of the adsorption assembly 100 on the bipolar plate reaches a better state. Of course, in order to ensure the adsorption stability of the first suction cup 10 on the membrane electrode, all the second suction cups 20 may also be disposed on the periphery of the first suction cup 10, so that there is no need to provide the first avoidance channel 105 for avoiding the second suction cup 20 on the first suction cup 10, thereby taking into account the adsorption performance of the adsorption assembly 100 on both the membrane electrode and the bipolar plate.

[0089] In some embodiments, Figure 1 , Figure 3 , Figure 8 and Fig. 9 As shown, each second suction cup 20 is movably disposed on the first suction cup 10 , and the second suction cup 20 can be lifted and lowered relative to the first suction cup 10 via a lifting drive device 40 disposed on the cover plate 103 of the first suction cup 10 .

[0090] Specifically, the fixing portion 401 of the lifting drive device 40 is disposed on the cover plate 103 , and the driving end of the lifting drive device 40 is connected to the base plate 202 of the second suction cup 20 to drive the second suction cup 20 to perform lifting movement relative to the first suction cup 10 along the first direction.

[0091] Optionally, the lifting drive device 40 can be any form of a gear drive device, a sprocket chain drive device, a hydraulic drive device, a motor drive device or a cylinder drive device. As long as the lifting drive device 40 can drive the second suction cup 20 to perform lifting movement along the first direction, the embodiment of the present application does not limit the specific form of the lifting drive device 40.

[0092] When the first suction cup 10 absorbs the membrane electrode, in order to avoid interference between the sponge adsorption surface 201 of the second suction cup 20 and the membrane electrode, the control device of the stacking device 300 can control the movement of the lifting drive cylinder, and the second suction cup 20 is lifted by the lifting drive cylinder to make the sponge adsorption surface 201 move away from the porous adsorption surface 101 along the first direction, thereby ensuring that the sponge adsorption surface 201 of the second suction cup 20 can be away from the membrane electrode to avoid interference between the sponge adsorption surface 201 and the membrane electrode.

[0093] The reason for doing this is that the sponge adsorption surface 201 of the second suction cup 20 has certain compressibility and softness. If the second suction cup 20 is not lifted while the first suction cup 10 adsorbs the membrane electrode, the sponge adsorption surface 201 may contact the membrane electrode and cause unnecessary friction, extrusion or damage to the membrane electrode or the catalyst on the surface of the membrane electrode.

[0094] When the second suction cup 20 adsorbs the bipolar plate, since the sponge adsorption surface 201 has compressibility and deformability, the control device can control the lifting drive mechanism to drive the second suction cup 20 to extend downward along the first direction. In the process of adsorbing the bipolar plate, the sponge suction cup is compressed, thereby ensuring that the bipolar plate is tightly adsorbed on the sponge suction cup. If the second suction cup 20 is not extended downward by the lifting drive device 40, the porous adsorption surface 101 of the first suction cup 10 will interfere with the deformation of the sponge adsorption surface 201, and the sponge adsorption surface 201 cannot be fully deformed, and thus cannot form a tight adsorption on the bipolar plate. If leakage occurs, it will lead to failure of adsorption of the bipolar plate.

[0095] After the second suction cup 20 extends downward to adsorb the bipolar plate, the control device can control the lifting drive device 40 to drive the second suction cup 20 to rise, so that the sponge adsorption surface 201 is flush with the porous adsorption surface 101, so as to facilitate the subsequent visual positioning detection of the adsorption component 100.

[0096] It should be noted that the number of lifting drive devices 40 can be consistent with the number of second suction cups 20, that is, one lifting drive device 40 is configured for each second suction cup 20, and the control device can simultaneously control multiple lifting drive devices 40 to perform lifting movements synchronously to ensure that each second suction cup 20 extends downward synchronously, and the sponge adsorption surface 201 of each second suction cup 20 is fully deformed and stably adsorbs the bipolar plate at the same time, or to ensure that when the first suction cup 10 adsorbs the membrane electrode, each second suction cup 20 is lifted up synchronously to avoid the membrane electrode.

[0097] Of course, a plurality of second suction cups 20 may also be driven simultaneously by a lifting drive device 40, that is, each second suction cup 20 is connected to the driving end of the lifting drive device 40, so that the synchronization and consistency of the lifting operations of the plurality of second suction cups 20 can be ensured.

[0098] Therefore, as long as the lifting drive device 40 can ensure the synchronization of the lifting actions of the multiple second suction cups 20, the lifting drive device 40 can be configured according to actual needs, and the present application does not impose any restrictions on this.

[0099] In some embodiments, Figure 8 and Fig. 9 As shown, the lifting drive device 40 includes a slide cylinder, which includes a fixed part 401 and a sliding part 402 that can slide relative to the fixed part 401, and the sliding part 402 can slide relative to the fixed part 401 along a first direction. The fixed part 401 is fixedly arranged on the cover plate 103, and the sliding part 402 is connected to the base plate 202 of the second suction cup 20.

[0100] The structure of the slide cylinder is compact, and the sliding movement of the sliding part 402 is fast and smooth. The movement of the sliding part 402 along the first direction relative to the fixed part 401 has good guidance, so that the second suction cup 20 can be driven quickly, which helps to improve the working rhythm of the adsorption component 100.

[0101] In some embodiments, refer to Figure 6 and Figure 7 The first suction cup 10 further includes a second avoidance channel 106 extending along the first direction, that is, the second avoidance channel 106 extends through the cover plate 103 and the adsorption plate 104, and the second avoidance channel 106 is not connected to the cavity. The third suction cup 30 is disposed on the cover plate 103, and the cross-sectional area of ​​the second avoidance channel 106 is adapted to the shape of the third suction cup 30 to accommodate the third suction cup 30.

[0102] Furthermore, the non-contact adsorption surface 301 of the third suction cup 30 and the porous adsorption surface 101 of the first suction cup 10 avoid each other, and the non-contact adsorption surface 301 of the third suction cup 30 is exposed to the first suction cup 10, so that the third suction cup 30 can adsorb the gas diffusion layer.

[0103] The plurality of second avoidance channels 106 are distributed at intervals on the first suction cup 10 to ensure a balanced distribution of the third suction cup 30. Exemplarily, the plurality of second avoidance channels 106 are located on both sides of the first avoidance channel 105 to ensure optimal use of the space on the first suction cup 10.

[0104] Optionally, the first vent joint 108 and the second avoidance channel 106 of the first suction cup 10 may be arranged at intervals to further optimize the spatial layout on the cover plate 103 of the first suction cup 10 and form a balanced adsorption force on the gas diffusion layer.

[0105] In order to avoid interference between the porous adsorption surface 101 of the first suction cup 10 and the non-contact adsorption surface 301 of the third suction cup 30 , in some embodiments, the non-contact adsorption surface 301 of the third suction cup 30 is flush with the porous adsorption surface 101 of the first suction cup 10 .

[0106] It can be understood that if the non-contact adsorption surface 301 of the third suction cup 30 protrudes from the porous adsorption surface 101 of the first suction cup 10, a part of the adsorption holes 102 around the third suction cup 30 cannot form a vacuum cavity with the membrane electrode due to the interference of the third suction cup 30, thereby causing the vacuum adsorption force between the porous adsorption surface 101 and the membrane electrode to decrease. If the non-contact adsorption surface 301 of the third suction cup 30 is retracted into the second avoidance channel 106, the adsorption capacity of the third suction cup 30 on the gas diffusion layer will also be reduced, and at the same time, the porous adsorption surface 101 of the first suction cup 10 may also scratch the surface of the gas diffusion layer.

[0107] In this way, by keeping the non-contact adsorption surface 301 of the third suction cup 30 flush with the porous adsorption surface 101 of the first suction cup 10, the adsorption component 100 can take into account the adsorption capacity of both the membrane electrode and the gas diffusion layer, ensuring that the adsorption component 100 can stably adsorb both the membrane electrode and the gas diffusion layer.

[0108] In some embodiments, Figure 1 , Fig.10 and Fig.11 As shown, the adsorption assembly 100 further includes a mounting member 50 , and the mounting member 50 is used to fix the third suction cup 30 to the cover plate 103 of the first suction cup 10 .

[0109] Specifically, the back of the mounting member 50 is constructed in a strip shape, and both ends of the mounting member 50 are arranged across the second avoidance channel 106 and fixed to the cover plate 103. Both ends of the mounting member 50 have first mounting holes to facilitate fasteners to pass through the first mounting holes to fasten the mounting member 50 to the cover plate 103.

[0110] like Fig.12 As shown, a avoidance hole 501 is provided in the middle of the mounting member 50, and an air supply connector 302 is provided on the side of the third suction cup 30 facing away from the non-contact adsorption surface 301. The air supply connector 302 is used to connect to the air compressor. The air supply connector 302 extends from the avoidance hole 501 to facilitate connection with the air pipe of the air compressor located above the substrate 202.

[0111] A plurality of second mounting holes are further provided on the mounting member 50 around the avoidance hole 501 , so that the fastener can be fastened to the third suction cup 30 through the second mounting holes.

[0112] In this way, the third suction cup 30 can be stably mounted to the first suction cup 10 , and ensure that the non-contact adsorption surface 301 of the third suction cup 30 is flush with the porous adsorption surface 101 of the first suction cup 10 .

[0113] In some embodiments, refer to Figures 1 to 4The adsorption assembly 100 further includes a support plate 60 , which is disposed on the cover plate 103 of the first suction cup 10 . The support plate 60 is located on the peripheral side of the first suction cup 10 , and the support plate 60 is used to set the vacuum nozzle 70 .

[0114] The vacuum nozzle 70 is connected to the vacuum generator, and is used to adsorb the separator paper between the bipolar plate and the membrane electrode. In this way, while adsorbing the membrane electrode or bipolar plate, multiple vacuum nozzles 70 can simultaneously adsorb the separator paper. The conveying mechanism 3001 in the stacking device 300 can convey the separator paper to the NG (Non-Gripping) conveyor belt through the adsorption component 100, and then continue to convey the membrane electrode or bipolar plate to the next workstation, thereby improving the conveying rhythm and efficiency.

[0115] In a possible implementation, the number of support plates 60 can be multiple, and the multiple support plates 60 are respectively located on both sides of the first suction cup 10 along the second direction, that is, each of the two opposite sides of the first suction cup 10 along the second direction can be provided with a support plate 60 and a second suction cup 20.

[0116] For example, Figures 1 to 4 As shown, the support plates 60 can be arranged on the outside of the four corners of the first suction cup 10, that is, two support plates 60 can be arranged at both ends of one side of the first suction cup 10 along the second direction, and the second suction cup 20 is arranged between the two support plates 60.

[0117] Since the suction area of ​​the vacuum suction nozzle 70 is small, a plurality of vacuum suction nozzles 70 can be configured in the suction assembly 100, and the plurality of vacuum suction nozzles 70 are respectively installed on the support plate 60 and / or the second suction cup 20 located on the peripheral side of the first suction cup 10. In this way, the plurality of vacuum suction nozzles 70 can be evenly distributed on the peripheral side of the first suction cup 10 along the second direction, so that the spacer paper can be kept flat after being sucked, and the suction cup assembly can be ensured to have a reliable suction effect on the spacer paper.

[0118] In order to detect whether the adsorption material is successfully adsorbed, in some embodiments, such as 2, Figure 5 , Figure 6 and Figure 7 As shown, the first suction cup 10 also includes a third avoidance channel 107 that runs through the first direction, and the adsorption assembly 100 also includes a first detection assembly 80 for detecting whether the first suction cup 10, the second suction cup 20 or the third suction cup 30 adsorbs materials, and the first detection assembly 80 is arranged on the peripheral side of the third avoidance channel 107.

[0119] The third avoidance channel 107 passes through the cover plate 103 and the adsorption plate 104, and the third avoidance channel 107 is not connected to the cavity. Exemplarily, there can be two third avoidance channels 107, and the two third avoidance channels 107 can be located on both sides of the first avoidance channel 105 along the second direction, so as to reasonably utilize the space on the cover plate 103 of the first suction cup 10. Accordingly, there can also be multiple first detection components 80.

[0120] The first detection component 80 is arranged on the cover plate 103 and is located on the peripheral side of the third avoidance channel 107. The first detection component 80 may include a photoelectric sensor. The photoelectric sensor can emit and receive a detection light beam through the third avoidance channel 107, and then obtain the distance between the porous adsorption surface 101, the sponge adsorption surface 201 or the non-contact adsorption surface 301 and the material to be adsorbed, so as to determine whether the material of the first suction cup 10, the second suction cup 20 or the third suction cup 30 is adsorbed in place.

[0121] like Fig.12 As shown, an embodiment of the second aspect of the present application further provides an adsorption device 200, which includes an adsorption component 100 and a guide mechanism 2000 of any of the above embodiments of the present application, wherein the guide mechanism 2000 is connected to the adsorption component 100, and the guide mechanism 2000 is used to connect to the transport mechanism 3001.

[0122] It can be understood that the adsorption device 200 using the adsorption component 100 of the above embodiment has all the technical effects of the adsorption component 100 of the above embodiment, which will not be described in detail here.

[0123] Specifically, when the transport mechanism 3001 absorbs the material to be adsorbed through the adsorption device 200, the transport mechanism 3001 will perform a downward pressing operation to ensure that the adsorption component 100 in the adsorption device 200 is in full contact with the material to be adsorbed, so as to ensure that the adsorption component 100 adsorbs the material reliably and smoothly.

[0124] During the downward pressing process of the conveying mechanism 3001, the guide mechanism 2000 located between the conveying mechanism 3001 and the adsorption device 200 can ensure that the downward pressure acts evenly on the adsorption component 100, thereby ensuring that the adsorption surface of the adsorption component 100 is flat and not skewed and is in flat contact with the material to be adsorbed, so as to stably adsorb the material to be adsorbed.

[0125] In some embodiments, Figures 12 to 17 As shown, the guide mechanism 2000 includes a mounting plate 2100 and a guide buffer assembly 2200 . The mounting plate 2100 is used to connect with the transport mechanism 3001 , and the guide buffer assembly 2200 is disposed on the mounting plate 2100 and the adsorption assembly 100 .

[0126] like Fig.12As shown, the mounting plate 2100 can be constructed as a flat plate structure and has a strong structural strength to bear the weight of the entire adsorption assembly 100. The mounting plate 2100 is provided with a plurality of threaded holes to be firmly connected with the transport mechanism 3001.

[0127] The guide buffer assembly 2200 is arranged on the mounting plate 2100 and the adsorption assembly 100. When the mounting plate 2100 moves toward the adsorption assembly 100 under the pressure of the conveying mechanism 3001, the guide buffer assembly 2200 can make the distance between the mounting plate 2100 and the adsorption assembly 100 adjustable along the first direction, thereby guiding the movement of the mounting plate 2100 while also providing overpressure protection for the adsorption assembly 100.

[0128] In order to achieve the guiding and buffering performance of the guiding buffer assembly 2200, in some embodiments, as Fig.13 and Fig.14 As shown, the guide buffer assembly 2200 includes a linear bearing 2201, a guide shaft 2202 extending along a first direction, a bracket 2203 and an elastic member 2204. The linear bearing 2201 is arranged on the mounting plate 2100, the guide shaft 2202 is penetrated through the mounting plate 2100, so that the linear bearing 2201 can be sleeved on the outside of the guide shaft 2202, the bracket 2203 is installed at the end of the guide shaft 2202, the elastic member 2204 is sleeved on the outside of the guide shaft 2202, and the two ends of the elastic member 2204 are respectively abutted against the mounting plate 2100 and the bracket 2203.

[0129] The guide shaft 2202 and the linear bearing 2201 are used together and can be configured into multiple groups. The guide shaft 2202 guides the linear motion of the linear bearing 2201 along the first direction, so that the mounting plate 2100 always approaches or moves away from the adsorption component 100 along the first direction, and forms a balanced downward pressure on the adsorption component 100.

[0130] When the mounting plate 2100 is pressed toward the adsorption assembly 100 under the downward pressure of the transport mechanism 3001, the elastic member 2204 located between the mounting plate 2100 and the bracket 2203 will generate deformation and elastic force. The elastic force of the elastic member 2204 will form a certain buffer for the downward pressure operation of the transport mechanism 3001, and can form over-pressure protection for the adsorption assembly 100 when the downward pressure of the transport assembly is too large.

[0131] In this way, the guide buffer component 2200 can not only guide the movement of the mounting plate 2100 when the mounting plate 2100 moves close to the adsorption component 100, so that the mounting plate 2100 always presses against the adsorption component 100 along the first direction, so that the adsorption surface of the adsorption component 100 remains flat and not skewed, so as to evenly absorb the material to be adsorbed, and avoid the uneven adsorption surface of the adsorption component 100 affecting the adsorption effect. In addition, the guide buffer component 2200 can also buffer the downward movement of the adsorption component 100, so as to avoid the adsorption component 100 impacting the material to be adsorbed and causing damage to the material. When the downward pressure is too large, the elastic force generated by the elastic member 2204 increases, and the guide buffer component 2200 can also form overpressure protection for the adsorption component 100.

[0132] In some embodiments, Fig.13 As shown, the guide mechanism 2000 further includes a limit assembly 2300 , which is disposed on the mounting plate 2100 and the guide buffer assembly 2200 . The limit assembly 2300 is used to limit the distance that the mounting plate 2100 moves toward the adsorption assembly 100 .

[0133] The limiting component 2300 is used to limit the maximum travel of the mounting plate 2100 approaching the adsorption component 100 along the first direction. When the maximum travel is exceeded, the mounting plate 2100 cannot continue to move toward the adsorption component 100.

[0134] Specifically, the limit assembly 2300 includes a first limit member 2301 and a second limit member 2302 extending along a first direction, the first limit member 2301 is arranged on the mounting plate 2100, and the second limit member 2302 is arranged on the bracket 2203, the first limit member 2301 and the second limit member 2302 are arranged correspondingly along the first direction and have a first preset distance, and the first preset distance is the above-mentioned maximum stroke.

[0135] When the mounting plate 2100 moves in the first direction close to the adsorption assembly 100 under the downward pressure of the conveying mechanism 3001, the first stopper 2301 gradually approaches the second stopper 2302 until it abuts against the second stopper 2302. In this way, the stopper cooperation between the first stopper 2301 and the second stopper 2302 can prevent the mounting plate 2100 from being excessively pressed toward the adsorption assembly 100, thereby protecting the adsorption assembly 100 from overpressure.

[0136] In order to further prevent the conveying mechanism 3001 from generating excessive pressure on the adsorption assembly 100, in some embodiments, as Fig.13 , Fig.14 and Fig.15As shown, the adsorption device 200 further includes a second detection component 2400 , which is disposed on the guide buffer component 2200 , and is used to detect the distance between the adsorption component 100 and the mounting plate 2100 .

[0137] The second detection component 2400 is used to detect the distance between the mounting plate 2100 and the adsorption component 100. When the distance between the mounting plate 2100 and the adsorption component 100 is less than a threshold value, the second detection component 2400 is triggered to generate an electrical signal and transmit it to the control device. The control device controls the conveying device to stop the pressing operation according to the electrical signal to prevent the conveying device from continuing to press down and damaging the adsorption component 100.

[0138] Furthermore, the second detection component 2400 includes a sensor 2401 and a detection piece 2402, the sensor 2401 is arranged on the bracket 2203, the sensor 2401 has a detection port, the detection piece 2402 is arranged on the mounting plate 2100 and extends along the first direction, when the mounting plate 2100 is not subjected to the pressure of the conveying mechanism 3001, the end of the detection piece 2402 has a second preset distance from the detection port along the first direction, when the mounting plate 2100 moves toward the adsorption component 100 under the pressure of the conveying mechanism 3001, the end of the detection piece 2402 moves toward the detection port until it can extend into the detection port after moving the second preset distance, the sensor 2401 is triggered to generate an electrical signal, and the control device controls the conveying mechanism 3001 to stop the pressing operation according to the electrical signal.

[0139] Optionally, the second preset distance can be smaller than the first preset distance, so that before the limiting component 2300 limits the mounting plate 2100, the second detection component 2400 can be triggered in advance, and the control device can promptly control the conveying mechanism 3001 to stop moving, so as to avoid the first limiting member 2301 and the second limiting member 2302 from causing impact due to hard contact.

[0140] like Fig.18 As shown, the third aspect of the embodiments of the present application further provides a stacking device 300 , which includes the adsorption device 200 and a conveying mechanism 3001 of any of the above embodiments of the present application, and the adsorption device 200 is installed on the conveying mechanism 3001 .

[0141] It can be understood that the stacking device 300 using the adsorption device 200 of the above embodiment has all the technical effects of the adsorption device 200 of the above embodiment, which will not be described in detail here.

[0142] The transport mechanism 3001 may be a manipulator, and the adsorption device 200 is mounted on the six-axis flange of the manipulator. Optionally, the transport mechanism 3001 may also be a crane. As long as the adsorption device 200 can be transported and transferred, the specific form of the transport mechanism 3001 is not limited in the embodiment of the present application.

[0143] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
