Description

Technical Field

[0001] This invention relates to the field of hydrogen energy battery production technology, specifically to a press-fit composite structure for hydrogen energy battery production. Background Technology

[0002] A hydrogen fuel cell is a clean energy device that directly converts chemical energy into electrical energy through the electrochemical reaction of hydrogen and oxygen. Its working principle is that hydrogen is decomposed into protons and electrons under the catalytic action of the anode. The protons are transferred to the cathode through the electrolyte membrane, while the electrons form an electric current through the external circuit. Finally, the hydrogen combines with oxygen at the cathode to produce water. It has advantages such as zero carbon emissions, high energy efficiency, and fast hydrogen refueling speed.

[0003] A fuel cell stack is composed of multiple single cell structures stacked together. Each single cell is a symmetrical structure consisting of a bipolar plate, a gas diffusion layer, a proton exchange membrane, a gas diffusion layer, and a bipolar plate. In the actual production process, the above-mentioned multiple layers need to be stacked in sequence and then hot-pressed together using equipment to achieve the assembly of the single cell structure.

[0004] Existing press-fitting equipment for hydrogen energy single-cell structures typically has only one press-fitting station. The press-fitting process is divided into feeding, hot-pressing composite, cooling, and unloading steps, resulting in long press-fitting time and low production efficiency per cycle. In addition, in order to ensure that the ionomers in the catalyst have sufficient contact with the surface of the proton exchange membrane and that they penetrate and fuse with each other, as well as to ensure that the internal stress of the material is redistributed and gradually relaxed, so that the thickness of the entire membrane electrode is uniform, it is usually necessary to hold the pressure for 30-60 seconds during the hot-pressing stage, which further prolongs the cycle of a single press-fitting process and makes it impossible to achieve continuous and efficient production. Summary of the Invention

[0005] The purpose of this invention is to provide a press-fit composite structure for hydrogen energy battery production to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A press-fit composite structure for hydrogen energy battery production includes a frame, a tray, a hot press groove, and a hot press plate. The tray is rotatably mounted on the frame via a first drive mechanism, which serves as the drive source.

[0012] Preferably, the air-cooled system includes a guide pipe and micropores; a guide pipe is fixed on the top of each hot plate, and each guide pipe is connected to the corresponding mounting cavity; a number of micropores are distributed on the lower surface of each hot plate, and each micropore is connected to the corresponding mounting cavity; each guide pipe is connected to the external air distribution system.

[0013] Preferably, each hot press tank has a pair of mounting holes A through the bottom of the side support plate on its inner wall. A round core A is rotatably installed in each of the two mounting holes A, and the top surface of the round core A is flush with the bottom wall of the hot press tank. Each side support plate is provided with a second linkage mechanism below it, which drives the two round cores A to rotate during the process of the side support plate moving from the cooling station to the unloading station.

[0014] Preferably, the second linkage mechanism includes a geared disc, a worm gear, a worm, a second linkage gear, and an arc-shaped rack D; the bottom of both circular cores A are coaxially fixed with geared discs via shaft A, and the two geared discs mesh with each other; the bottom of one geared disc is coaxially fixed with a worm gear via shaft B; each side support plate has a bracket fixed to its bottom, and a worm is rotatably mounted on each bracket, with the worm meshing with the worm gear; the end of each worm is correspondingly fixed with a second linkage gear; an arc-shaped rack D is fixed on the top surface of the frame between the cooling station and the unloading station; during the rotation of the disc frame, each second linkage gear can sequentially mesh with the arc-shaped rack D.

[0016] Preferably, both heating element A and heating element B are electric heating tubes.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0018] By sequentially setting up each workstation on the platform, and combining the first drive mechanism to drive the disk frame to rotate several side support plates and matching hot press grooves and hot press plates that are equidistantly distributed on the outer periphery, the pressing module composed of each hot press groove and hot press plate can simultaneously perform the processes of feeding, pressing, holding pressure, cooling, and unloading. This optimizes the traditional production line into a rotary continuous operation line, shortens the total cycle of a single pressing, and solves the problem of low production efficiency of traditional equipment.

[0019] The corresponding cooperation between the first linkage mechanism and each of the second drive mechanisms enables the press-fit module to continuously maintain the pressure and heat preservation state at the pressure preservation station. The pressure and heat preservation state is integrated into the circumferential production line, which does not affect the continuity of the rotation switching station and avoids prolonging the single process time of the pressure preservation process.

[0020] The guide tube and micropores form a cooling system. The external air distribution system introduces cold air into the guide tube and sprays it out from the micropores. On the one hand, it can help separate the top surface of the single cell structure from the hot press plate. On the other hand, it provides a cooling effect for the composite single cell structure. At the same time, during the hot pressing stage, the airflow can absorb the heat of the heating element B to form a heat flow, which is sprayed onto the upper layer of the single cell to play a role in assisting uniform heating.

[0021] When the side support plate moves from the cooling station to the unloading station, the linkage effect of the second linkage mechanism can drive the circular core A, circular core B and circular core C to rotate simultaneously, forming relative motion with the bottom surface of the single battery. This effectively avoids the problem of the interlayer bonding state being damaged during unloading due to the adhesion between the bottom surface of the single battery and the bottom wall of the hot pressing groove, ensuring the structural integrity of the finished product and reducing the defect rate.

[0042] Please see Figures 1-14This invention provides a press-fit composite structure for hydrogen energy battery production, including a frame 1, a tray 2, a hot press groove 3, and a hot press plate 5. The tray 2 is rotatably mounted on the frame 1 via a first drive mechanism 11, which serves as a drive source. The first drive mechanism 11 drives the tray 2 to rotate around its own axis. Several side support plates 21 are fixed at intervals on the outer peripheral wall of the tray 2. Each side support plate 21 is fixed with a hot press groove 3. Each side support plate 21 is provided with a second drive mechanism 4, and the moving part of the second drive mechanism 4 is equipped with a hot press plate 5. Specifically, the number and position of the hot press groove 3 and the hot press plate 5 in this application correspond one-to-one. There are six of each, and the hot press plate 5 is located directly above the hot press groove 3, thus forming six press-fit modules.

[0043] Secondly, the platform 1 has several workstations above it, namely, loading workstation 01, pressing workstation 02, pressure holding workstation 03, cooling workstation 04 and unloading workstation 05. During the rotation of the disk frame 2 driven by the first drive mechanism 11, the pressing module formed by the corresponding hot pressing groove 3 and hot pressing plate 5 can pass through each workstation in sequence. In addition, the platform 1 is provided with a first linkage mechanism 6 extending above the disk frame 2. During the rotation of the disk frame 2 driven by the first drive mechanism 11 and the synchronous rotation of each pressing module, the first linkage mechanism 6 is linked and cooperated with each second drive mechanism 4. Each hot pressing plate 5 is provided with an air cooling system for air cooling the single battery structure after composite.

[0044] It is worth noting that a loading robot and a unloading robot are respectively installed on the side of the platform 1 at the positions corresponding to the loading station 01 and the unloading station 05. Both loading and unloading robots adopt existing technology, and their specific structures and working principles will not be described in detail, and are not shown in the figure.

[0045] The method for pressing together the layers of a hydrogen fuel cell structure using this press-fitted composite structure is as follows:

[0046] Each side support plate 21 has a corresponding hot pressing groove 3 and a hot pressing plate 5, forming an independent pressing module. The first drive mechanism 11 drives the tray frame 2, the side support plates 21, and the components on the side support plates 21 to rotate. When the pressing module formed by the hot pressing groove 3 and the hot pressing plate 5 moves to the loading station 01 with the rotation of the tray frame 2, the hot pressing plate 5 is at its upper limit position. At this time, the distance between the hot pressing plate 5 and the hot pressing groove 3 is the largest. The specific state is as follows: Figure 6 As shown, space is made up for loading, and then the loading robot moves and stacks the layers of the single battery in sequence in the hot press tank 3.

[0047] The first drive mechanism 11 drives the disk frame 2 to continue rotating, moving the pressing module towards the pressing station 02. During this process, the corresponding second drive mechanism 4 works in conjunction with the first linkage mechanism 6 to drive the hot press plate 5 downwards, gradually reducing the distance between the hot press plate 5 and the hot press groove 3, until the pressing module moves to the position corresponding to the pressing station 02. At this point, the hot press plate 5 descends to its limit position and is pressed into the hot press groove 3, as shown in the image. Figure 13 As shown, the layers of a single cell can be compressed together to achieve composite structure.

[0048] As the first drive mechanism 11 drives the disk frame 2 to continue rotating, in order to move the above-mentioned pressing module to the pressure holding station 03, the corresponding second drive mechanism 4 separates from the first linkage mechanism 6, canceling the linkage effect. At this time, the hot press plate 5 continues to maintain the pressing state pressed into the hot press groove 3, achieving the pressure holding effect.

[0049] As the first drive mechanism 11 drives the disk frame 2 to continue rotating, thereby moving the aforementioned pressing module towards the cooling station 04, the corresponding second drive mechanism 4 works in conjunction with the first linkage mechanism 6 to drive the hot press plate 5 upward a predetermined distance, causing the hot press plate 5 to separate from the hot press groove 3, as shown in the following state. Figure 14 As shown, gaps are made to allow air cooling airflow. When the pressing module moves to the cooling station 04, the air cooling system on the hot press plate 5 works to form air cooling airflow, which blows onto the composite single cell structure to achieve cooling.

[0050] The first drive mechanism 11 drives the disk frame 2 to continue rotating, causing the above-mentioned pressing module to move to the lower material station 05. During this process, the corresponding second drive mechanism 4 works in conjunction with the first linkage mechanism 6 to drive the hot press plate 5 to the limit position. At this time, the distance between the hot press plate 5 and the hot press groove 3 is the largest, making room for unloading. Then, the unloading robot unloads and transfers the cooled single battery from the hot press groove 3.

[0051] After the hot press trough 3 is unloaded, it returns to an empty state. Then, the first drive mechanism 11 continues to drive the platen 2 to rotate, which moves the unloaded hot press trough 3 to the loading station 01 to complete one pressing cycle. In the above process, the pressing modules at other positions can repeat the corresponding steps in sequence, thus realizing continuous pressing processing.

[0052] As a preferred embodiment, the hot press tanks 3 in this application are arranged at equal intervals. The distances the pressing module travels from the loading station 01 to the pressing station 02, from the pressure holding station 03 to the cooling station 04, from the cooling station 04 to the unloading station 05, and from the unloading station 05 to the loading station 01 are all the same. This distance is defined as A. Figure 8As shown, the distance the pressing module travels from the pressing station 02 to the cooling station 04 is 2A. That is, when the pressing module passes through the pressure holding station 03 in the pressure holding state, it actually travels for the equivalent of the distance between two stations, thus ensuring that the pressure holding time is sufficient.

[0053] like Figure 11 As shown, the hot pressing groove 3 has rectangularly distributed clamping cavities 31, and several heating elements A32 are evenly distributed in the clamping cavities 31. The hot pressing plate 5 has an installation cavity 51, and several heating elements B52 are evenly distributed in the installation cavity 51. Both heating elements A32 and heating elements B52 are electric heating tubes. During the press-fitting process, the heat generated by the heating element A32 can heat the hot pressing groove 3, and the heat generated by the heating element B52 can heat the pressing plate 5, thereby achieving the hot pressing bonding effect and ensuring that the layers of the single cell are more tightly bonded. Example 2

[0054] Please see Figure 3 , Figures 6-8 This embodiment, based on embodiment 1, explains and describes the second driving mechanism 4 and the first linkage mechanism 6 as follows:

[0055] The second drive mechanism 4 includes a threaded rod 41, a nut seat 43, and a first linkage gear 44. The threaded rod 41 is vertically and rotatably mounted on the side support plate 21. The nut seat 43 is threadedly fitted onto the threaded rod 41, and a connecting arm 431 is fixed to the side of the nut seat 43. The ends of the connecting arms 431 are respectively fixed to the hot press plate 5. Each side support plate 21 is vertically fixed with a guide rod 42. Each nut seat 43 is slidably fitted onto the corresponding guide rod 42. The top of each threaded rod 41 is fixed with a first linkage gear 44, and each first linkage gear 44 is linked and cooperates with the first linkage mechanism 6.

[0056] The linkage between the first linkage mechanism 6 and the first linkage gear 44 includes the first linkage mechanism 6 driving the first linkage gear 44 to rotate in the forward direction and the first linkage mechanism 6 driving the first linkage gear 44 to rotate in the reverse direction. The first linkage mechanism 6 includes a vertical rod 61, an arc-shaped rack A63, an arc-shaped rack B64, and an arc-shaped rack C65. The vertical rod 61 is vertically fixed on the frame 1 and extends through to the top of the disk frame 2, and is rotatably connected to the disk frame 2. The top of the vertical rod 61 is connected to the wall rod 6. 2. Arc-shaped racks A63, B64, and C65 are fixed respectively. Arc-shaped rack A63 is distributed between the loading station 01 and the pressing station 02, and meshes with each of the first linkage gears 44 from the outside. Arc-shaped rack B64 is distributed between the pressure holding station 03 and the cooling station 04. Arc-shaped rack C65 is distributed between the cooling station 04 and the unloading station 05, and both mesh with each of the first linkage gears 44 from the inside.

[0057] During the process of the side support plate 21 moving from the loading station 01 to the pressing station 02, the arc-shaped rack A63 meshes with the corresponding first linkage gear 44, which can drive the first linkage gear 44 and the threaded rod 41 to rotate forward. The rotating threaded rod 41 can drive the nut seat 43 to move down along the guide rod 42. Under the fixed connection of the connecting arm 431, it can drive the hot press plate 5 to move down synchronously, providing effective drive for the hot press plate 5 to move down for pressing.

[0058] During the process of the side support plate 21 moving from the pressure holding station 03 to the cooling station 04, the arc rack B64 meshes with the corresponding first linkage gear 44, which can drive the first linkage gear 44 and the threaded rod 41 to rotate in opposite directions. The reversed threaded rod 41 can drive the nut seat 43 to move upward along the guide rod 42, and under the fixed connection of the connecting arm 431, it can drive the hot press plate 5 to move upward to the predetermined air cooling height.

[0059] During the process of the side support plate 21 moving from the cooling station 04 to the unloading station 05, the arc-shaped rack C65 meshes with the corresponding first linkage gear 44, which can drive the first linkage gear 44 and the threaded rod 41 to continue to rotate in the opposite direction. Similarly, it can drive the hot press plate 5 to continue to move upward to the limit position to facilitate subsequent unloading and loading. Example 3

[0060] Please see Figure 12 Based on Examples 1 and 2, this example explains the air-cooling system:

[0061] The air-cooled system includes a guide pipe 53 and micro-holes 54. Each hot plate 5 has a guide pipe 53 fixed on its top. Each guide pipe 53 is connected to the corresponding mounting cavity 51. Each hot plate 5 has a number of micro-holes 54 distributed on its lower surface. Each micro-hole 54 is connected to the corresponding mounting cavity 51. Each guide pipe 53 is connected to the external air distribution system (not shown in the diagram).

[0062] During the process of the pressing module moving from the pressure holding station 03 to the cooling station 04, when the first linkage mechanism 6 and the corresponding second drive mechanism 4 work together to drive the hot pressing plate 5 upward, the heating elements A32 and B52 stop heating. The external gas distribution system pumps cold air into the guide pipe 53, and guides the cold air into the mounting cavity 51 through the guide pipe 53. Finally, the cold air is sprayed downward through the micro-hole 54 onto the composite single battery structure. On the one hand, under the action of the spraying air pressure, the top surface of the single battery structure is separated from the lower end surface of the hot pressing plate 5, so that the formed single battery structure can remain in the hot pressing groove 3, which is convenient for subsequent unloading. On the other hand, when the hot pressing plate 5 moves upward to the air cooling position, the cold air blows on the top surface of the single battery and flows out from the gap between the hot pressing plate 5 and the hot pressing groove 3. The hot pressing plate 5, the single battery structure and the hot pressing groove 3 can be cooled by air cooling. When the pressing module is at the cooling station 04, the cooling work can continue.

[0063] In addition, during the process of the pressing module moving from the loading station 01 to the pressing station 02, both heating element A32 and heating element B52 are in working state, providing heat support for hot pressing composite. At the same time, the external gas distribution system works, pumping gas into the guide pipe 53. The gas flows through the gaps between the heating elements B52, absorbing the heat of the heating elements B52 to form a hot airflow. The hot airflow is finally ejected through the micropores 54 and blown downwards onto the top layer of the single cell structure to achieve auxiliary heating and ensure that the middle part of each layer of the single cell structure is heated evenly.

[0064] As the hot press plate 5 continues to descend, it ensures that the single cell layer structure is enhanced by a thermal gradient, avoiding sudden temperature changes. In addition, the pressure of the heat flow impact on the uppermost layer of the single cell structure gradually increases, which can press the battery layer structure downward, making each layer structure conform to the structure inside the hot press groove 3, avoiding the presence of warped edges that would affect the subsequent pressing quality. Example 4

[0065] Please see Figure 4 , Figure 9 and Figure 10 The difference between this embodiment and embodiment 3 is as follows:

[0066] Each hot pressing tank 3 has a pair of mounting holes A701 that penetrate the bottom of the side support plate 21 on its inner wall. A round core A7 is rotatably installed in each of the two mounting holes A701. The top surface of the round core A7 is flush with the bottom wall of the hot pressing tank 3. The round core A7 is in close contact with the inner wall of the mounting hole A701 to ensure the quality of the bottom layer of the battery. Each side support plate 21 is provided with a second linkage mechanism 8, which is used to drive the two round cores A7 to rotate during the process of the side support plate 21 moving from the cooling station 04 to the unloading station 05.

[0067] The second linkage mechanism 8 includes a gear disc 82, a worm gear 84, a worm 85, a second linkage gear 86, and an arc-shaped rack D87. The bottom of the two circular cores A7 are coaxially fixed with a gear disc 82 via a shaft A81, and the two gear discs 82 mesh with each other. The bottom of one gear disc 82 is coaxially fixed with a worm gear 84 via a shaft B83. The bottom of each side support plate 21 is fixed with a bracket 851, and a worm 85 is rotatably mounted on each bracket 851, and the worm 85 meshes with the worm gear 84. The end of each worm 85 is fixed with a corresponding second linkage gear 86. An arc-shaped rack D87 is fixed on the top surface of the frame 1 between the cooling station 04 and the unloading station 05. During the rotation of the disc frame 2, each second linkage gear 86 can mesh with the arc-shaped rack D87 in sequence.

[0068] As the pressing module moves from the cooling station 04 to the unloading station 05, the second linkage gear 86 can contact and mesh with the arc-shaped rack D87. The arc-shaped rack D87 meshes and drives the second linkage gear 86, which in turn drives the worm 85 to rotate. The rotating worm 85 can mesh and drive the worm wheel 84, which in turn drives the corresponding gear disk 82 to rotate. The rotating gear disk 82 drives another gear disk 82 to rotate, which in turn drives the two circular cores A7 to rotate simultaneously. The rotating circular cores A7 generate relative movement with the bottom surface of the single battery to assist in separating from the bottom surface of the single battery structure. This prevents the bonding state between battery layers from being damaged due to the adhesion and entanglement between the bottom surface of the single battery structure and the internal structure of the hot pressing groove 3 during subsequent unloading.

[0069] Please see Figure 9 and Figure 10 On the inner bottom wall of the hot press trough 3, there are mounting holes B702 on both sides between the two mounting holes A701, which penetrate the bottom surface of the side support plate 21. A round core B71 is rotatably installed in each of the two mounting holes B702, and the top surface of the round core B71 is flush with the inner bottom wall of the hot press trough 3. The bottom end of each round core B71 is coaxially fixed with a gear A712 through a connecting shaft A711. Each gear A712 meshes with one of the gear discs 82. On the inner bottom wall of the hot press trough 3, there are mounting holes C703 at the four corners, which penetrate the bottom surface of the side support plate 21. A round core C72 is rotatably installed in each of the four mounting holes C703, and the top surface of the round core C72 is flush with the inner bottom wall of the hot press trough 3. The bottom of each round core C72 is coaxially fixed with a gear B722 through a connecting shaft B721. Each gear B722 meshes with the gear disc 82 on the corresponding side.

[0070] When the measuring disk 82 rotates, it can drive each gear A712 and gear B722 to rotate simultaneously, thereby driving each round core B71 and round core C72 to rotate simultaneously. The rotating round cores B71 and C72 and round core A7 compensate for each other, ensuring that the area that moves relative to the bottom surface of the battery structure is sufficient to cover most of the bottom of the hot pressing groove 3. Example 5

[0071] Please see Figure 5 The difference between this embodiment and embodiment 4 is that:

[0072] Specifically, the first drive mechanism 11 includes a cylindrical base 111, a driven gear ring 112, a drive motor 113, and a main gear 114. The cylindrical base 111 is rotatably mounted on the top surface of the frame 1, the disc frame 2 is fixed to the top of the cylindrical base 111, the upright rod 61 passes through the inside of the cylindrical base 111, the driven gear ring 112 is fixed on the outer wall of the cylindrical base 111, the drive motor 113 is fixed on the top of the frame 1, and the main gear 114 is fixed on the output shaft of the drive motor 113, and the main gear 114 meshes with the driven gear ring 112.

[0073] The drive motor 113 operates, and its output shaft can drive the main gear 114 to rotate. The rotating main gear 114 can mesh with and drive the driven gear ring 112 to rotate the cylinder seat 111, which in turn can drive the disc frame 2 to rotate, providing effective drive for the station switching of the pressing module.

[0074] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Therefore, the present invention will not explain the control method and circuit connection in detail.

[0075] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
