[0002] Currently, in the fuel cell field, hydrogen fuel cells are chemical devices that convert the chemical energy of hydrogen fuel into electrical energy. Because hydrogen fuel cells convert the chemical energy of fuel into electrical energy through electrochemical reactions, they are not subject to the constraints of the Carnot cycle effect and therefore have high efficiency. The stack core of a hydrogen fuel cell stack is composed of alternating bipolar plates (bipolar plates are the combination of the cathode and anode plates of a hydrogen fuel cell, primarily conducting electrons) and membrane electrodes (membrane electrodes are the core components of proton exchange membrane fuel cells). To improve the stacking efficiency of the bipolar plates and membrane electrodes, the bipolar plates and membrane electrodes are typically prefabricated by bonding them together. This is achieved by applying glue to one side of the bipolar plates, manually assembling them, and curing the glue with a UV light source (ultraviolet light source, also known as ultraviolet curing light source, uses high-energy ultraviolet light-emitting diodes to emit a point-shaped UV light spot, used to quickly cure UV-sensitive materials such as UV glue) to bond and seal the bipolar plates to the membrane electrodes, ultimately forming a battery assembly.

[0003] The existing traditional manual assembly of bipolar plates and membrane electrodes requires workers to manually align the bipolar plates and membrane electrodes after dispensing glue, manually lock the assembly tooling, and flip the tooling 180 degrees before transporting it to a UV curing box for irradiation, so that the UV glue between the bipolar plates and the membrane electrodes is cured, and then a battery assembly is obtained; however, the above manual assembly of bipolar plates and membrane electrodes has many disadvantages, including but not limited to: low alignment accuracy of bipolar plates and membrane electrodes, unstable assembly quality, low assembly efficiency, low efficiency of manual frequent opening and closing and transportation of assembly tooling, high labor intensity, and high safety risks.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] like Figures 1 to 2 As shown, an embodiment of the present invention provides a bonding and curing device, including: a lifting assembly 20, a first bearing assembly 30, a flip drive assembly 40, a second bearing assembly 50 and a light curing assembly 60; the first bearing assembly 30 is located above the second bearing assembly 50, the lifting assembly 20 is arranged between the first bearing assembly 30 and the second bearing assembly 50, the first bearing assembly 30 is connected to the lifting assembly 20 through the flip drive assembly 40, and the flip drive assembly 40 is used to drive the first bearing assembly 30 to flip (or the first bearing assembly 30 is flippable relative to the lifting assembly 20; the flip drive assembly 40 is arranged on the lifting assembly 20); wherein, the first bearing assembly 30 is used to carry and flip the bipolar plate 70, the second bearing assembly 50 is used to carry the membrane electrode 80, the lifting assembly 20 is used to lift the first bearing assembly 30 to drive the bipolar plate 70 to press against the membrane electrode 80, and the light curing assembly 60 is used to irradiate the bipolar plate 70 and the membrane electrode 80 to cure the glue between the two.

[0035] The present invention realizes the flipping of the bipolar plate 70 and the production action of pressing and fixing the bipolar plate 70 and the membrane electrode 80 with a set pressure by setting the lifting component 20, the first bearing component 30, the flip driving component 40 and the second bearing component 50, and then cooperates with the light curing component 60 to efficiently cure the glue between the bipolar plate 70 and the membrane electrode 80, thereby realizing high-precision assembly of the bipolar plate 70 and the membrane electrode 80; compared with the manual assembly method in the prior art, the present invention avoids the problem of unqualified alignment accuracy caused by human error, and effectively improves the alignment accuracy and assembly between the bipolar plate 70 and the membrane electrode 80 The quality is improved, the assembly efficiency is improved, the manual labor is effectively replaced, and the labor intensity of the staff is reduced; and, because the manual labor is effectively replaced, the probability of the staff being directly exposed to the light emitted by the light curing component 60 is reduced, thereby reducing the safety risk and effectively protecting the safety and health of the staff; the utility model has a simple structure and low cost, is easy to assemble and subsequently maintain, and is suitable for large-scale promotion and use. It is found in actual use that the utility model not only improves the overall packaging efficiency of the fuel cell, but also ensures the packaging quality of the fuel cell, and can be well applied to large-scale fuel cell production lines. At the same time, it can also significantly improve production capacity and reduce production costs.

[0036] In another embodiment of the present invention, the bonding and curing device further includes a frame assembly 10 , and the lifting assembly 20 , the second bearing assembly 50 , and the light curing assembly 60 are all disposed on the frame assembly 10 .

[0037] like Figures 1 to 2 As shown, the first supporting assembly 30 includes a vacuum adsorber 31, a first supporting body 32 and at least one first positioning block 33. The first supporting body 32 is rotatably arranged on the lifting assembly 20 and is driven and connected to the flip driving assembly 40 (for example, the first supporting body 32 is rotatably connected to the lifting assembly 20 through the flip driving assembly 40); the first positioning block 33 is arranged on the surface of the first supporting body 32 for limiting the bipolar plate 70; the vacuum adsorber 31 is arranged on the first supporting body 32 for adsorbing and fixing the bipolar plate 70 on the surface of the first supporting body 32.

[0038] By providing the vacuum adsorber 31, the bipolar plate 70 is reliably fixed on the surface of the first carrier 32 while avoiding damage to the bipolar plate 70. By providing at least one first positioning block 33, high-precision positioning of the bipolar plate 70 is achieved with a simple structure, thereby ensuring the subsequent press-fit accuracy of the bipolar plate 70 and the membrane electrode 80.

[0039] In a specific embodiment of the present invention, in order to ensure the reliable flipping of the first carrier 32, the following two structural matching relationships can be adopted: 1. The lifting assembly 20 is used as a frame, and the first carrier 32 is rotatably set on the lifting assembly 20. The flipping drive assembly 40 is also set on the lifting assembly 20 and is driven and connected to the first carrier 32 to drive the first carrier 32 to rotate; 2. The fixed end of the flipping drive assembly 40 is connected to the lifting assembly 20, and the rotating end is driven and connected to the first carrier 32 to drive the first carrier 32 to rotate; at this time, the first carrier 32 is only set on the flipping drive assembly 40 and has no direct connection with the lifting assembly 20; the above two structural matching relationships can be flexibly selected according to actual usage requirements and factors such as the mass of the first carrier 32.

[0040] In another specific embodiment of the present invention, the vacuum adsorber 31 further has an airflow regulating device, which can adjust the adsorption force according to the size and shape of the bipolar plate 70 to be suitable for the packaging of bipolar plates 70 of various sizes and shapes, thereby improving the packaging accuracy and efficiency.

[0041] like Figure 1 As shown, the second carrier assembly 50 includes a second carrier 51 and at least one second positioning block 52. The second carrier 51 is arranged on the frame assembly 10, and at least a portion of it is made of light-transmitting material; the second positioning block 52 is arranged on the surface of the second carrier 51 and is used to limit the membrane electrode 80; wherein, the light emitted by the light curing assembly 60 is incident between the membrane electrode 80 and the bipolar plate 70 through the portion of the light-transmitting material on the second carrier 51; the light curing assembly 60 is located below the second carrier 51.

[0042] By setting at least one second positioning block 52, high-precision positioning of the membrane electrode 80 is achieved with a simple structure, thereby ensuring the subsequent compression fit accuracy of the bipolar plate 70 and the membrane electrode 80; by setting at least a part of the second carrier 51 to be made of light-transmitting material, reliable passage of light is ensured, thereby ensuring the light curing effect.

[0043] In a specific embodiment of the present invention, the second carrier 51 is entirely made of a light-transmitting material, preferably a quartz glass material, which not only ensures uniform irradiation of the subsequent UV light source (i.e., the ultraviolet light source 61), but also effectively reduces costs and facilitates subsequent cleaning and maintenance.

[0044] In another specific embodiment of the present invention, positioning pins and positioning holes are respectively provided on the first carrier 32 and the second carrier 51. The corresponding cooperation between the positioning pins and the positioning holes ensures the precise alignment of the bipolar plate 70 and the membrane electrode 80, further improving the accuracy and efficiency of the packaging.

[0045] like Figure 1As shown, the bonding and curing device also includes a safety grating assembly 90, which is arranged on the outside of the second supporting assembly 50 (for example, arranged on the frame assembly 10); the safety grating assembly 90 is used to emit a blocking light curtain, which is at least located on the outside of the second supporting assembly 50, and is at least used to remind staff to stay away from the second supporting assembly 50.

[0046] Because ultraviolet rays are usually harmful to human skin and eyes, protective measures should be taken when using a UV light source (i.e., ultraviolet light source 61), such as wearing protective glasses and gloves. Ultraviolet rays also have a destructive effect on certain materials and objects, such as organic glass and plastics. When using a UV light source, direct exposure to these objects should be avoided. Therefore, the present invention can effectively remind workers to stay away from the second supporting component 50 by providing a safety grating component 90, thereby achieving distance from ultraviolet rays, which not only protects the safety and health of workers, but also avoids the UV light source from being damaged by bumps, thereby increasing its service life and ensuring the stability and safety of the light source.

[0047] In a specific embodiment of the present invention, the safety light curtain assembly 90 can be electrically connected to the central controller and automatically stop working when it detects that a worker is approaching the working area (i.e., when there is contact with the blocking light curtain), thereby effectively preventing accidental injury to the worker and providing a safe working environment for the worker.

[0048] It should be noted that the safety light grid in the present invention, also known as a light curtain or light grid protection device, is a device used to protect the safety of personnel and equipment. It forms a protective barrier between the equipment and the operator by emitting and receiving infrared or visible light sources. When an object (such as a hand or body part) enters this protection area, the light beam is blocked, triggering the safety light grid to send a signal, thereby achieving an emergency stop or deceleration of the equipment to prevent accidents. In a specific embodiment of the present invention, the structure of the safety light grid mainly includes the following parts: 1. Transmitter: The transmitter is responsible for emitting a light source of a certain frequency and intensity, such as infrared. It usually contains one or more transmitting windows and a light source driving circuit; 2. Receiver: The receiver is responsible for receiving the light source emitted by the transmitter and converting it into an electrical signal. It usually contains one or more receiving windows and a light signal detection circuit; 3. Controller: The controller is the core part of the safety light grid. It is responsible for processing signals between the transmitter and the receiver, as well as communicating with other devices. When the receiver detects that the light beam is blocked, the controller will send a corresponding control signal, such as emergency stop, deceleration or other safety measures; 4. Power supply: The power supply provides power to the various parts of the safety grating, usually including a power adapter and power circuit; 5. Connecting wire: The connecting wire connects the various parts of the safety grating together to realize signal transmission and communication.

[0049] The working process of the safety light grid is as follows: 1. The transmitter emits light: When the equipment is started, the transmitter starts to emit a light source of a certain frequency and intensity; 2. Light source transmission: The light source propagates between the equipment and the operator to form a protective barrier; 3. Light source reception: The receiver receives the light source emitted by the transmitter and converts it into an electrical signal; 4. Signal processing: The controller processes the signal between the transmitter and the receiver to determine whether the light beam is blocked; 5. Control output: When the controller detects that the light beam is blocked, it will send a corresponding control signal, such as emergency stop, deceleration or other safety measures; 6. Equipment response: After receiving the control signal from the controller, the equipment will execute corresponding safety measures, such as emergency stop or deceleration, to prevent accidents; the safety light grid in this utility model provides reliable safety protection for operators and equipment.

[0050] like Figure 1 As shown, the bonding and curing device also includes a central controller and an operating button 100. The central controller is electrically connected to at least one of the lifting assembly 20, the flip drive assembly 40 and the light curing assembly 60 to control their operation; the operating button 100 is electrically connected to the central controller to control the central controller to start or stop the bonding and curing operation.

[0051] This arrangement achieves controllability of the working process of the bonding and curing device and provides structural support for subsequent automated production.

[0052] In a specific embodiment of the present invention, the operation button 100 can be a touch-type start button or a mechanical emergency stop button, which is arranged in a prominent position on the operation panel of the central controller, making the operation more intuitive and convenient, and can respond quickly in an emergency. It is suitable for various production environments, especially production lines in emergency situations that require quick response, thereby improving the safety and operating efficiency of the production line.

[0053] In another specific embodiment of the present invention, the central controller is a programmable logic controller (PLC controller), which can achieve precise control of the light intensity and irradiation time of the ultraviolet light source 61 and the ultraviolet irradiator 62 through a closed-loop control strategy. It can flexibly adjust parameters according to different packaging materials and process requirements, and is suitable for production environments with various complex process requirements, thereby improving the controllability of the production process and product quality.

[0054] like Figure 1 As shown, the frame assembly 10 includes a carrier frame 11, multiple universal wheels 12 and multiple leveling structures 13; the multiple universal wheels 12 are arranged at intervals at the bottom of the carrier frame 11 for carrying and driving the carrier frame 11 to move; the multiple leveling structures 13 are arranged at the bottom of the carrier frame 11 for adjusting the level of the upper surface of the carrier frame 11; the lifting assembly 20 and the second bearing assembly 50 are respectively arranged on the upper surface of the carrier frame 11.

[0055] By providing multiple universal wheels 12, the transport frame 11 is easily moved; by providing multiple leveling structures 13, the level of the upper surface of the lifting assembly 20, the second bearing assembly 50 and the transport frame 11 is ensured, thereby improving the compression fit accuracy of the bipolar plate 70 and the membrane electrode 80.

[0056] In a specific embodiment of the present invention, the universal wheel 12 also has a self-locking function so as to fix the carrier body 11 at any time.

[0057] In another specific embodiment of the present invention, the carrier frame 11 can be made of aluminum alloy material and have a reinforcing beam design, so that the entire frame is more stable and can withstand higher workloads. It is suitable for high-strength and high-precision production environments and can ensure the stable operation of the production line and the consistency of the products.

[0058] like Figure 1 and Figure 2 As shown, the light curing assembly 60 includes a UV light source 61 and a UV irradiator 62. The UV light source 61 is arranged at the bottom of the frame assembly 10 and is optically connected to the UV irradiator 62 for generating UV light within a set wavelength range; the UV irradiator 62 is arranged on the frame assembly 10 for irradiating UV light at a set angle and / or a set intensity to the glue between the bipolar plate 70 and the membrane electrode 80.

[0059] This arrangement not only ensures the working reliability of the light curing assembly 60 , but also simplifies the structure of the light curing assembly 60 .

[0060] In a specific embodiment of the present invention, the wavelength range of the ultraviolet light emitted by the ultraviolet light source 61 is 365nm to 405nm. This wavelength range can effectively stimulate the curing reaction of UV glue and is suitable for various materials that require UV curing, thereby improving the versatility and adaptability of the device.

[0061] like Figure 1 As shown, the lifting assembly 20 includes two groups of lifting structures 21, each group of lifting structures 21 includes a lifting bracket 211, a lifting cylinder 212 and a sliding member 213, the sliding member 213 is slidably set on the lifting bracket 211, and is driven and connected to the lifting cylinder 212; the lifting cylinder 212 is used to drive the sliding member 213 to move up and down; wherein, the lifting brackets 211 of the two groups of lifting structures 21 are arranged at intervals on the frame assembly 10, and are located at both ends of the first bearing assembly 30; the lifting cylinders 212 of the two groups of lifting structures 21 are arranged at intervals on the frame assembly 10; the sliding members 213 of the two groups of lifting structures 21 are respectively rotatably connected to the two ends of the first bearing assembly 30; the flipping drive assembly 40 is arranged on the sliding member 213 of one of the groups of lifting structures 21.

[0062] This arrangement not only ensures the working reliability of the lifting assembly 20, but also simplifies the structure of the lifting assembly 20.

[0063] like Figure 1 and Figure 2 As shown, the flip drive assembly 40 includes a flip cylinder 41, which is arranged on the lifting assembly 20 and is used to drive the first bearing assembly 30 to flip; the bonding and curing device also includes a main air circuit 110, which is arranged below the frame assembly 10 and is connected to the flip drive assembly 40 and / or the lifting assembly 20 air circuit; the main air circuit 110 is connected to an external air source and is used to drive the flip drive assembly 40 and / or the lifting assembly 20 to work.

[0064] By providing the main air circuit 110 , the flip drive assembly 40 and / or the lifting assembly 20 can be reliably driven; by providing the flip cylinder 41 , the structure of the flip drive assembly 40 is simplified, thereby effectively reducing costs.

[0065] The present invention also provides a fuel cell assembly device, which includes the above-mentioned bonding and curing device; the fuel cell assembly device also includes a manipulator, which is used to place the bipolar plate 70 at a specified position on the first supporting component 30, and to place the membrane electrode 80 at a specified position on the second supporting component 50.

[0066] The fuel cell assembly device proposed in the present invention realizes high-precision, high-strength, and high-sealing bonding and sealing between the bipolar plate 70 and the membrane electrode 80 by setting a robot and a bonding and curing device to work together, effectively replacing the manual method and avoiding problems such as unstable product quality and high safety risks.

[0067] In a specific embodiment of the present invention, the fuel cell assembly device and / or the bonding and curing device also includes a position sensor for precisely controlling the installation position and downward pressing position of the bipolar plate 70, thereby ensuring precise and close contact between the bipolar plate 70 and the membrane electrode 80, so as to be suitable for packaging processes requiring high-precision pressure control and improve the accuracy and efficiency of packaging.

[0068] The specific working process and principle of the present invention are now described in detail as follows:

[0069] The bipolar plate 70 is placed manually or by a robot on top of the first supporting assembly 30, and the membrane electrode 80 is placed manually or by a robot on top of the second supporting assembly 50. The second supporting assembly 50 is made of a UV-transmissive material, such as quartz glass or acrylic. The safety grating assembly 90 is used to prevent workers from entering the dangerous area during the installation of the UV curing device (i.e., the light curing assembly 60) and causing safety accidents. The operation button 100 is triggered by the worker after the bipolar plate 70 and membrane electrode 80 are loaded, and the UV curing device automatically starts to work.

[0070] like Figure 1 As shown, the first carrier assembly 30 includes a first positioning block 33 and a vacuum absorber 31. The first positioning block 33 is mounted on the first carrier 32 to position the bipolar plate 70. The vacuum absorber 31 provides vacuum negative pressure to enable the first carrier assembly 30 to absorb and fix the bipolar plate 70.

[0071] like Figure 2 As shown, the lifting assembly 20 and the flip drive assembly 40 include a flip cylinder 41, a connecting block, a lifting structure 21, a module mounting block and other structures; the frame assembly 10 is above the platform plate, the second bearing assembly 50 is installed on the platform plate, and the first bearing assembly 30 is connected and cooperated with the lifting assembly 20 and the flip drive assembly 40 respectively; the flip cylinder 41 is installed on the connecting block of the lifting assembly 20, and the other end is connected to the first bearing assembly 30, and is used to drive the first bearing assembly 30 to flip 180° after the first bearing assembly 30 adsorbs the bipolar plate 70; the lifting structure 21 is installed on the frame assembly 10 and is located on the module mounting block. After the flip cylinder 41 flips the first bearing assembly 30 180°, it drives the upper connecting block, the flip cylinder 41 and the first bearing assembly 30 to descend, so that the bipolar plate 70 is fitted with the membrane electrode 80 above the second bearing assembly 50. At the same time, the lifting structure 21 can maintain the set pressure to make the bipolar plate 70 and the membrane electrode 80 fit tightly;

[0072] like Figure 1 and Figure 2 As shown, the light curing assembly 60 consists of a UV irradiator 62 and a UV light source 61. The central controller controls the operation of the UV irradiator 62 and the gas system of the main gas path 110. The UV irradiator 62 is installed under the platform plate of the rack assembly 10. The carrier frame 11 is a hollow structure, which allows the UV light emitted by the UV irradiator 62 to pass through. The UV light emitted by the UV irradiator 62 passes through the second carrier assembly 50 and the membrane electrode 80, so that the UV glue between the bipolar plate 70 and the membrane electrode 80 is cured, thereby achieving the purpose of bonding and sealing the bipolar plate 70 and the membrane electrode 80.
