Description

Technical Field

[0001] The utility model belongs to the technical field of hydrogen fuel cell production, and specifically relates to an assembly device for hydrogen energy fuel cell production. Background Art

[0002] A hydrogen energy fuel cell is a power generation device that uses a chemical reaction between hydrogen and oxygen to generate electrical energy. The hydrogen fuel cell works through the reverse reaction of electrolyzing water, that is, hydrogen and oxygen are respectively supplied to the anode and the cathode. At the anode, the electrons in the hydrogen atoms are separated and reach the cathode through an external circuit, where they recombine with oxygen atoms and hydrogen ions to form water. During the whole process, only water and heat are generated, and no harmful substances are emitted. Therefore, hydrogen fuel cell vehicles are truly zero-emission and zero-pollution vehicles. During normal use, in order to increase the battery capacity, multiple hydrogen fuel cells are usually connected in series and assembled to form a battery pack to meet the usage requirements.

[0003] During the assembly process of the hydrogen fuel cell stack, due to the large overall volume of the battery stack, an assembly device is usually used to assist in the production and assembly. The general assembly device is usually a clamping device that can move in three axes. During use, an electric gripper is used to grab the battery and displace it to a specified position for assembly. This clamping method only relies on two relatively close grippers to achieve grasping. When facing some batteries with a relatively high height, due to the clamping force only existing at the left and right ends, the battery is prone to shaking, affecting the clamping stability.

[0004] At the same time, when clamping multiple hydrogen fuel cells, the electric gripper used will rely on the clamping force to clamp the outermost battery, while the middle battery is clamped by friction. This clamping method will cause the friction force to decrease due to vibration when the device shakes, and then cause the middle battery to fall off, posing a relatively large safety hazard. Summary of the Invention

[0005] The purpose of the utility model is to provide an assembly device for hydrogen energy fuel cell production to solve the problems raised in the above background art.

[0006] To achieve the above object, the present utility model provides the following technical solution: An assembly device for hydrogen energy fuel cell production, comprising two frames. At the top of each of the two frames, an adjustment guide rail is fixedly installed. Above the adjustment guide rail, a longitudinal electric slide is provided. The bottom end of the longitudinal electric slide is movably clamped between the two adjustment guide rails. The longitudinal electric slide moves back and forth relative to the adjustment guide rail. A transverse electric slide is movably clamped to the front of the longitudinal electric slide. The transverse electric slide moves left and right relative to the longitudinal electric slide. At the bottom end of the transverse electric slide, an electric push rod is fixedly installed. The output end of the electric push rod is fixedly installed with a machine base. On the left and right sides of the bottom end of the machine base, longitudinal guide rails are fixedly installed. At the bottom ends of the longitudinal guide rails, transverse guide rails are vertically installed. Inside the longitudinal guide rails and the transverse guide rails, a lateral clamping assembly is provided. The lateral clamping assembly is movably clamped between the longitudinal guide rails and the transverse guide rails. An activity frame located below the machine base is installed between the two lateral clamping assemblies. At the bottom ends of the two lateral clamping assemblies, bottom support assemblies are fixedly installed. A liquid storage assembly is installed between the machine base and the activity frame. At the top end of the machine base, a first three-way valve is fixedly installed. The left and right ends of the first three-way valve are fixedly communicated with circulation pipes. The ends of the circulation pipes far from the first three-way valve are fixedly communicated with second three-way valves. The bottom ends of the second three-way valves are communicated with the bottom support assemblies. The ends of the second three-way valves far from the circulation pipes are fixedly communicated with liquid infusion pipes. The other ends of the liquid infusion pipes are communicated with the liquid storage assembly. The bottom end of the first three-way valve is communicated with the top end of the liquid storage assembly.

[0007] Before use, it is necessary to fix the bottom end of the frame to the ground and connect the power supply of the device. Among them, the longitudinal electric slide can move back and forth along the adjustment guide rail to realize the front and back transportation of the hydrogen fuel cell, and the transverse electric slide can move left and right along the longitudinal electric slide to realize the left and right transportation of the hydrogen fuel cell. At the same time, the electric push rod can drive the up and down transportation of the hydrogen fuel cell to complete the three-axis movement process of the hydrogen fuel cell.

[0008] As a further technical solution of the present utility model, the liquid storage assembly includes a liquid storage pipe. The top end of the liquid storage pipe is connected to the middle of the bottom end of the machine base. An oil return hole is opened at the top end of the liquid storage pipe. The oil return hole is communicated with the bottom end of the first three-way valve. A one-way valve is installed inside the oil return hole and the direction of the valve is to conduct towards the inside of the liquid storage pipe and cut off towards the outside of the liquid storage pipe.

[0009] As a further technical solution of the present utility model, oil delivery holes are opened on the left and right sides near the top end of the liquid storage pipe. The oil delivery holes are communicated with the liquid infusion pipes. A one-way valve is installed inside the oil delivery holes and the direction of the valve is to conduct towards the outside of the liquid storage pipe and cut off towards the inside of the liquid storage pipe.

[0010] As a further technical solution of the utility model, the internal movable sleeve of the liquid storage tube is provided with a first piston plate, the bottom end of the first piston plate is fixedly connected with a first piston rod, the bottom end of the first piston rod passes through the bottom end of the liquid storage tube and is connected to the top end of the movable frame.

[0011] When the hydrogen fuel cell needs to be clamped, the base can be moved to the top of the hydrogen fuel cell. At this time, the liquid storage assembly is in the initial state, that is, the distance between the movable frame and the base is the maximum value. When the movable frame and the hydrogen fuel cell correspond to each other, the base can be driven to move downward by turning on the electric push rod until the bottom end of the movable frame contacts the top end of the hydrogen fuel cell. At this time, the downward displacement can still be maintained, and the movable frame can move upward under the lifting effect of the hydrogen fuel cell.

[0012] When the movable frame moves upward, it can synchronously drive the first piston rod to move upward. At this time, the first piston plate moves upward accordingly. The hydraulic oil inside the liquid storage tube is then discharged from the oil delivery hole under the action of pressure and enters the interior of the liquid delivery tube. When clamping, the one-way valve at the connection between the No. 2 three-way valve and the liquid delivery tube can be kept open, while the one-way valve at the connection between the No. 2 three-way valve and the circulation tube is closed. At this time, the hydraulic oil inside the No. 2 three-way valve can enter the interior of the bottom support assembly to complete the transfer.

[0013] As a further technical solution of the utility model, a one-way valve is installed at the connection point between the No. 2 three-way valve and the infusion tube, and the direction of the valve is to conduct to the inside of the No. 2 three-way valve and to shut off to the outside of the No. 2 three-way valve. A one-way valve is installed at the connection point between the No. 2 three-way valve and the circulation tube, and the direction of the valve is to conduct to the outside of the No. 2 three-way valve and to shut off to the inside of the No. 2 three-way valve.

[0014] Among them, when clamping, the one-way valve at the connection between the No. 2 three-way valve and the infusion pipe must be kept open, while the one-way valve at the connection between the No. 2 three-way valve and the circulation pipe must be closed. The hydraulic oil discharged through the infusion pipe can enter the interior of the bottom support assembly through the No. 2 three-way valve. When unloading, the one-way valve at the connection between the No. 2 three-way valve and the circulation pipe can be kept open, while the one-way valve at the connection between the No. 2 three-way valve and the infusion pipe must be closed. At this time, the No. 2 three-way valve can discharge the hydraulic oil from the circulation pipe and return it to the interior of the No. 1 three-way valve, and finally return to the interior of the liquid storage assembly.

[0015] As a further technical solution of the utility model, the lateral clamping assembly includes a longitudinal guide block, which is movably connected to the longitudinal guide rail and can be displaced up and down relative to the longitudinal guide rail, one side of the longitudinal guide block is connected to the movable frame, and the side of the longitudinal guide block away from the movable frame is fixedly connected to a first fixed seat, the side of the first fixed seat away from the longitudinal guide block is movably connected to a connecting rod through a rotating shaft, and the end of the connecting rod away from the first fixed seat is movably connected to a second fixed seat through a rotating shaft.

[0016] As a further technical solution of the present utility model, transverse guide blocks are fixedly connected to the bottom ends of the second fixing seats. The transverse guide blocks are movably clamped with the transverse guide rails and displace left and right relative to the transverse guide rails. A longitudinal extension frame is fixedly connected to the bottom end of the longitudinal guide block. The bottom end of the longitudinal extension frame is connected to the bottom support assembly. Transverse extension frames are fixedly installed on the front and rear sides of the bottom end of the transverse guide block. The ends of the transverse extension frames far from the transverse guide blocks are fixedly connected to lateral clamping plates located above the bottom support assembly.

[0017] When the movable frame moves upward, at this time the longitudinal guide block moves upward accordingly. At this time, the connecting rod deflects towards the inner side and applies a pulling force to the transverse guide block. When the longitudinal guide block moves upward, it can apply a pulling force to the bottom support assembly to drive the bottom support assembly to move upward. And the transverse guide block moves towards the middle of the movable frame, and can synchronously drive the transverse extension frame and the lateral clamping plate to move towards the middle of the movable frame until one side of the lateral clamping plate contacts the side of the hydrogen fuel cell and applies a force to clamp the hydrogen fuel cell between two corresponding lateral clamping plates. At this time, both ends of the hydrogen fuel cell can contact the lateral clamping plates, and the top end contacts the movable frame to complete the clamping process.

[0018] By utilizing the downward displacement of the device during clamping, the hydrogen fuel cell can reversely apply a jacking force, so that the top end of the hydrogen fuel cell can always contact the movable frame. And when the movable frame moves upward, it can be converted into the clamping force of the lateral clamping plate to realize the clamping of the side of the hydrogen fuel cell, so that the top end and the side end of the hydrogen fuel cell can be limited, avoiding the problem that the top end of the traditional device lacks limitation and is prone to shaking when facing a relatively high hydrogen fuel cell, and significantly improving the clamping stability.

[0019] As a further technical solution of the present utility model, the bottom support assembly includes a bottom guide rail. The top end of the bottom guide rail is connected to the bottom end of the longitudinal extension frame. A bottom guide block is movably clamped inside the bottom guide rail. The bottom guide block displaces left and right relative to the bottom guide rail. Bottom extension rods are fixedly connected to the sides of the bottom guide block close to the middle of the machine base. One end of the bottom extension rod penetrates through one end of the bottom guide rail and is fixedly connected to a support plate.

[0020] As a further technical solution of the present utility model, temporary storage pipes are fixedly connected to the ends of the bottom guide rail far from the middle of the machine base. An exchange pipe is fixedly communicated with the top end of the temporary storage pipe and on the side far from the bottom guide rail. The other end of the exchange pipe is fixedly communicated with the bottom end of the second three-way valve.

[0021] As a further technical solution of the utility model, a second piston plate is movably sleeved inside the temporary storage tube, and one end of the second piston plate close to the bottom guide block is fixedly connected to a second piston rod, the side of the second piston rod away from the second piston plate passes through one side of the temporary storage tube and is connected to the bottom guide block, and the side of the second piston plate away from the second piston rod is fixedly connected to a limit spring located inside the temporary storage tube, and the other end of the limit spring is connected to one end of the inner cavity of the temporary storage tube.

[0022] When the hydraulic oil enters the bottom support assembly, the hydraulic oil can be introduced into the temporary storage tube through the exchange tube and exert force on the second piston plate. At this time, the limit spring is stretched and drives the second piston rod to move away from the exchange tube. At this time, the support plate on one side moves toward the middle of the movable frame, that is, the two support plates are relatively close to each other, and with the upward displacement of the support plates, the bottom end of the hydrogen fuel cell placed on the tray can be supported, completing the bottom support process and assisting in the clamping process.

[0023] By utilizing the hydraulic oil transferred during clamping and coordinating the design of the one-way valve and pipeline, the device can support the bottom of the hydrogen fuel cell after completing the clamping of the hydrogen fuel cell. When the device clamps a batch of hydrogen fuel cells, it can provide support for the bottom of the hydrogen fuel cell in the middle, avoiding the problem of the hydrogen fuel cell in the middle of the traditional device relying solely on friction to clamp, thereby improving safety redundancy and reducing safety hazards.

[0024] When the hydrogen fuel cell reaches the designated position and needs to be unloaded, the one-way valve at the connection between the No. 2 three-way valve and the circulation pipe can be opened. At this time, the limit spring automatically resets, and the hydraulic oil inside the temporary storage pipe can flow back to the No. 2 three-way valve, and be discharged through the circulation pipe, and then flow back to the inside of the storage pipe through the No. 1 three-way valve. At this time, the two support plates move away from each other to release the bottom support, and the movable frame moves down and drives the support plate to move down. At the same time, the corresponding side clamps move away from each other until the hydrogen fuel cell is placed and the unloading process is completed.

[0025] By utilizing the reset process of the device, the device can release the bottom support and move downward and release the side limit at the same time when the device is tilting the material, so that the hydrogen fuel cell can slowly move downward and slowly release the bottom limit and the side limit until the hydrogen fuel cell is stably placed in the specified position, so that there is a certain buffer when unloading, avoiding the impact caused by rapid unloading that affects the quality of the hydrogen fuel cell and improving the unloading stability.

[0026] The beneficial effects of the utility model are as follows:

[0027] 1. The utility model utilizes the downward displacement of the device during clamping, so that the hydrogen fuel cell can apply a lifting force in the reverse direction, so that the top of the hydrogen fuel cell can always be in contact with the movable frame, and when the movable frame moves upward, it can be converted into a clamping force of the lateral clamping plate to achieve side clamping of the hydrogen fuel cell, so that the top and side ends of the hydrogen fuel cell can be limited, avoiding the problem of shaking caused by the lack of limit at the top of the traditional device when facing a higher hydrogen fuel cell, and significantly improving the clamping stability.

[0028] 2. The utility model utilizes the hydraulic oil transferred during clamping, and cooperates with the design of the one-way valve and the pipeline, so that after the device completes the clamping of the hydrogen fuel cell, it can also support its bottom, so that when the device clamps a batch of hydrogen fuel cells, it can provide support for the bottom end of the hydrogen fuel cell in the middle, avoiding the problem of the traditional device that the hydrogen fuel cell in the middle is clamped only by friction, thereby improving safety redundancy and reducing safety hazards.

[0029] 3. The utility model utilizes the reset process of the device so that when the device is carrying out inclined material, the bottom support can be released and the downward displacement and side limit can be released at the same time, so that the hydrogen fuel cell can slowly move downward while slowly releasing the bottom limit and the side limit until the hydrogen fuel cell is stably placed in the specified position, so that there is a certain buffer when unloading, avoiding the impact caused by rapid unloading that affects the quality of the hydrogen fuel cell, and improving the unloading stability.

Specific embodiments

[0040] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0041] Such as Figures 1 to 9As shown in the figure, in the embodiment of the present utility model, an assembly device for hydrogen energy fuel cell production includes two frames 1. At the top of each of the two frames 1, an adjustment guide rail 2 is fixedly installed. Above the adjustment guide rail 2, there is a longitudinal electric slide 3. The bottom end of the longitudinal electric slide 3 is movably clamped between the two adjustment guide rails 2. The longitudinal electric slide 3 moves back and forth relative to the adjustment guide rail 2. A transverse electric slide 4 is movably clamped to the front of the longitudinal electric slide 3. The transverse electric slide 4 moves left and right relative to the longitudinal electric slide 3. At the bottom end of the transverse electric slide 4, an electric push rod 5 is fixedly installed. The output end of the electric push rod 5 is fixedly installed with a machine base 6. On the left and right sides of the bottom end of the machine base 6, longitudinal guide rails 7 are fixedly installed. At the bottom ends of the longitudinal guide rails 7, transverse guide rails 8 are vertically installed. Inside the longitudinal guide rails 7 and the transverse guide rails 8, there is a lateral clamping assembly 15. The lateral clamping assembly 15 is movably clamped between the longitudinal guide rails 7 and the transverse guide rails 8. Between the two lateral clamping assemblies 15, there is a movable frame 14 located below the machine base 6. At the bottom ends of the two lateral clamping assemblies 15, bottom support assemblies 16 are fixedly installed. Between the machine base 6 and the movable frame 14, a liquid storage assembly 13 is installed. At the top of the machine base 6, a first three-way valve 9 is fixedly installed. The left and right ends of the first three-way valve 9 are fixedly connected to circulation pipes 12. The ends of the circulation pipes 12 far from the first three-way valve 9 are fixedly connected to second three-way valves 10. The bottom ends of the second three-way valves 10 are connected to the bottom support assemblies 16. The ends of the second three-way valves 10 far from the circulation pipes 12 are fixedly connected to infusion pipes 11. The other ends of the infusion pipes 11 are connected to the liquid storage assembly 13. The bottom end of the first three-way valve 9 is connected to the top end of the liquid storage assembly 13.

[0042] Before use, it is necessary to fix the bottom end of the frame 1 to the ground and connect the power supply of the device. Among them, the longitudinal electric slide 3 can move back and forth along the adjustment guide rail 2 to realize the front and back transportation of the hydrogen fuel cell, while the transverse electric slide 4 can move left and right along the longitudinal electric slide 3 to realize the left and right transportation of the hydrogen fuel cell. At the same time, the electric push rod 5 can drive the up and down transportation of the hydrogen fuel cell to complete the three-axis movement process of the hydrogen fuel cell.

[0043] As Figure 2 and Figure 5As shown, the liquid storage assembly 13 includes a liquid storage pipe 131, the top of the liquid storage pipe 131 is connected to the middle of the bottom of the machine base 6, the top of the liquid storage pipe 131 is provided with an oil return hole 135, the oil return hole 135 is connected to the bottom of the No. 1 three-way valve 9, a one-way valve is installed inside the oil return hole 135, and the direction of the valve is to conduct to the inside of the liquid storage pipe 131 and to cut off to the outside of the liquid storage pipe 131, and the left and right sides of the liquid storage pipe 131 near the top are provided with oil delivery holes 135. 4. The oil delivery hole 134 is connected with the liquid delivery pipe 11. A one-way valve is installed inside the oil delivery hole 134. The direction of the valve is to conduct to the outside of the liquid storage pipe 131 and to cut off to the inside of the liquid storage pipe 131. The first piston plate 132 is movably sleeved inside the liquid storage pipe 131. The bottom end of the first piston plate 132 is fixedly connected with the first piston rod 133. The bottom end of the first piston rod 133 passes through the bottom end of the liquid storage pipe 131 and is connected to the top end of the movable frame 14.

[0044] When the hydrogen fuel cell needs to be clamped, the base 6 can be moved to the top of the hydrogen fuel cell. At this time, the liquid storage assembly 13 is in the initial state, that is, the distance between the movable frame 14 and the base 6 is the maximum value. When the movable frame 14 and the hydrogen fuel cell correspond to each other, the base 6 can be driven to move downward by turning on the electric push rod 5 until the bottom end of the movable frame 14 contacts the top end of the hydrogen fuel cell. At this time, the downward displacement can still be maintained. At this time, the movable frame 14 can move upward under the lifting effect of the hydrogen fuel cell.

[0045] When the movable frame 14 moves up, it can synchronously drive the first piston rod 133 to move up. At this time, the first piston plate 132 moves up accordingly. The hydraulic oil located inside the liquid storage tube 131 is then discharged from the oil delivery hole 134 under the action of pressure and enters the interior of the liquid infusion tube 11. When clamping, the one-way valve at the connection between the No. 2 three-way valve 10 and the liquid infusion tube 11 can be kept normally open, while the one-way valve at the connection between the No. 2 three-way valve 10 and the circulation tube 12 is closed. At this time, the hydraulic oil inside the No. 2 three-way valve 10 can enter the interior of the bottom support assembly 16 to complete the transfer.

[0046] like Figure 2 and Figure 3 As shown, a one-way valve is installed at the connection between the No. 2 three-way valve 10 and the infusion tube 11, and the direction of the valve is to conduct to the inside of the No. 2 three-way valve 10 and to shut off to the outside of the No. 2 three-way valve 10. A one-way valve is installed at the connection between the No. 2 three-way valve 10 and the circulation tube 12, and the direction of the valve is to conduct to the outside of the No. 2 three-way valve 10 and to shut off to the inside of the No. 2 three-way valve 10.

[0047] Among them, when clamping, the one-way valve at the connection between the second three-way valve 10 and the infusion tube 11 needs to be kept open, while the one-way valve at the connection between the second three-way valve 10 and the circulation tube 12 needs to be kept closed. The hydraulic oil exported through the infusion tube 11 can enter the interior of the bottom support assembly 16 through the second three-way valve 10. When discharging, the one-way valve at the connection between the second three-way valve 10 and the circulation tube 12 can be kept open, while the one-way valve at the connection between the second three-way valve 10 and the infusion tube 11 is kept closed. At this time, the second three-way valve 10 can export the hydraulic oil from the circulation tube 12 and return it to the interior of the first three-way valve 9, and finally return to the interior of the liquid storage assembly 13.

[0048] As Figure 2 and Figure 6 as well as Figure 7 shown, the lateral clamping assembly 15 includes a longitudinal guide block 151. The longitudinal guide block 151 is movably clamped with the longitudinal guide rail 7 and is displaced up and down relative to the longitudinal guide rail 7. One side of the longitudinal guide block 151 is connected to the movable frame 14. On the side of the longitudinal guide block 151 away from the movable frame 14, first fixed seats 153 are fixedly connected. One end of the connecting rod 155 away from the first fixed seat 153 is movably connected to the second fixed seat 154 through a rotating shaft. The bottom ends of the second fixed seats 154 are fixedly connected with transverse guide blocks 152. The transverse guide blocks 152 are movably clamped with the transverse guide rail 8 and are displaced left and right relative to the transverse guide rail 8. The bottom end of the longitudinal guide block 151 is fixedly connected with a longitudinal extension frame 156. The bottom end of the longitudinal extension frame 156 is connected to the bottom support assembly 16. On the front and rear sides of the bottom end of the transverse guide block 152, transverse extension frames 157 are fixedly installed. One end of the transverse extension frame 157 away from the transverse guide block 152 is fixedly connected with a lateral clamping plate 158 located above the bottom support assembly 16.

[0049] Embodiment: When the movable frame 14 moves upward, at this time the longitudinal guide block 151 moves upward accordingly. At this time, the connecting rod 155 deflects towards the inner side and applies a pulling force to the transverse guide block 152. When the longitudinal guide block 151 moves upward, it can apply a pulling force to the bottom support assembly 16 to drive the bottom support assembly 16 to move upward. And the transverse guide block 152 moves towards the middle of the movable frame 14, and can synchronously drive the transverse extension frame 157 and the lateral clamping plate 158 to move towards the middle of the movable frame 14 until one side of the lateral clamping plate 158 contacts the side of the hydrogen fuel cell and applies a force to clamp the hydrogen fuel cell between two corresponding lateral clamping plates 158. At this time, both ends of the hydrogen fuel cell can contact the lateral clamping plate 158, and the top end contacts the movable frame 14 to complete the clamping process.

[0050] By utilizing the downward displacement of the device during clamping, the hydrogen fuel cell can apply a reverse lifting force, enabling the top of the hydrogen fuel cell to always be in contact with the movable frame 14. When the movable frame 14 moves upward, it can be converted into the clamping force of the lateral clamping plate 158 to clamp the side of the hydrogen fuel cell, so that the top and side ends of the hydrogen fuel cell can be limited, avoiding the problem that the top lacks limitation and is prone to shaking when the traditional device faces a relatively high hydrogen fuel cell, and significantly improving the clamping stability.

[0051] As Figure 6 and Figure 7 and Figure 8 and Figure 9 shown, the bottom support assembly 16 includes a bottom guide rail 161. The top end of the bottom guide rail 161 is connected to the bottom end of the longitudinal extension frame 156. A bottom guide block 162 is movably clamped inside the bottom guide rail 161. The bottom guide block 162 displaces left and right relative to the bottom guide rail 161. On one side of the bottom guide block 162 close to the middle of the machine base 6, a bottom extension rod 163 is fixedly connected. One end of the bottom extension rod 163 penetrates through one end of the bottom guide rail 161 and is fixedly connected to a support plate 164. On one end of the bottom guide rail 161 far from the middle of the machine base 6, a temporary storage pipe 165 is fixedly connected. On the top end of the temporary storage pipe 165 and on the side far from the bottom guide rail 161, an exchange pipe 169 is fixedly communicated. The other end of the exchange pipe 169 is fixedly communicated with the bottom end of the second three-way valve 10. A second piston plate 166 is movably sleeved inside the temporary storage pipe 165. On one end of the second piston plate 166 close to the bottom guide block 162, a second piston rod 167 is fixedly connected. On the side of the second piston rod 167 far from the second piston plate 166, it penetrates through one side of the temporary storage pipe 165 and is connected to the bottom guide block 162. On the side of the second piston plate 166 far from the second piston rod 167, a limiting spring 168 located inside the temporary storage pipe 165 is fixedly connected. The other end of the limiting spring 168 is connected to one end of the inner cavity of the temporary storage pipe 165.

[0052] Embodiment: When hydraulic oil enters the inside of the bottom support assembly 16, at this time, the hydraulic oil can be introduced into the inside of the temporary storage pipe 165 through the exchange pipe 169, and a force is applied to the second piston plate 166. At this time, the limiting spring 168 is stretched accordingly, and the second piston rod 167 is driven to displace in a direction away from the exchange pipe 169. At this time, one side of the support plate 164 displaces toward the middle of the movable frame 14, that is, the two support plates 164 approach each other relatively. With the upward displacement of the support plate 164, the bottom end of the hydrogen fuel cell placed on the tray can be supported, completing the bottom support process and assisting in completing the clamping process.

[0053] By utilizing the hydraulic oil transported during clamping and cooperating with the design of one-way valves and pipelines, after the device clamps the hydrogen fuel cell, it can also support the bottom of the fuel cell. When the device clamps a batch of hydrogen fuel cells, it can support the bottom ends of the hydrogen fuel cells in the middle, avoiding the problem that the hydrogen fuel cells in the middle of the traditional device rely only on friction for clamping, improving the safety redundancy, and reducing potential safety hazards.

[0054] When the hydrogen fuel cell reaches the designated position and needs to be unloaded, the one-way valve at the connection between the second three-way valve 10 and the circulation pipe 12 can be opened. At this time, the limit spring 168 automatically resets, and the hydraulic oil inside the temporary storage pipe 165 can flow back to the second three-way valve 10 and be exported through the circulation pipe 12, and then re-flow back into the inside of the liquid storage pipe 131 through the first three-way valve 9. At this time, the two support plates 164 move away from each other to release the bottom support, and at the same time, the movable frame 14 moves downward and drives the support plate 164 to move downward. At the same time, the corresponding lateral clamping plates 158 move away from each other until the hydrogen fuel cell is placed, completing the unloading process.

[0055] By utilizing the reset process of the device, when the device discharges the material obliquely, it can simultaneously release the bottom support, move downward, and release the side limit. The hydrogen fuel cell can slowly move downward while slowly releasing the bottom limit and the side limit until the hydrogen fuel cell is stably placed at the designated position, providing a certain buffer during unloading, avoiding the impact caused by rapid unloading on the quality of the hydrogen fuel cell, and improving the unloading stability.

[0056] Working principle and usage process:

[0057] Before use, the bottom end of the frame 1 needs to be fixed to the ground and the device power supply needs to be connected. Among them, the longitudinal electric slide 3 can move back and forth along the adjustment guide rail 2 to realize the front and back transportation of the hydrogen fuel cell, and the transverse electric slide 4 can move left and right along the longitudinal electric slide 3 to realize the left and right transportation of the hydrogen fuel cell. At the same time, the electric push rod 5 can drive the up and down transportation of the hydrogen fuel cell to complete the three-axis movement process of the hydrogen fuel cell;

[0058] When it is necessary to clamp the hydrogen fuel cell, the base 6 can be moved directly above the hydrogen fuel cell. At this time, the liquid storage assembly 13 is in the initial state, that is, the distance between the movable frame 14 and the base 6 is the maximum value. When the movable frame 14 corresponds to the hydrogen fuel cell, the electric push rod 5 can be opened to drive the base 6 to move downward until the bottom end of the movable frame 14 contacts the top end of the hydrogen fuel cell. At this time, the downward movement can still be maintained, and at this time, the movable frame 14 can move upward under the jacking action of the hydrogen fuel cell;

[0059] When the movable frame 14 moves upward, it can synchronously drive the first piston rod 133 to move upward, and at this time, the first piston plate 132 moves upward accordingly, and the hydraulic oil in the liquid storage tube 131 is then discharged from the oil delivery hole 134 under the action of pressure, and enters the interior of the liquid delivery tube 11. When clamping, the one-way valve at the connection between the No. 2 three-way valve 10 and the liquid delivery tube 11 can be kept normally open, and the one-way valve at the connection between the No. 2 three-way valve 10 and the circulation tube 12 can be closed. At this time, the hydraulic oil in the No. 2 three-way valve 10 can enter the interior of the bottom support assembly 16 to complete the transfer;

[0060] When clamping, the one-way valve at the connection between the No. 2 three-way valve 10 and the infusion pipe 11 needs to be kept open, while the one-way valve at the connection between the No. 2 three-way valve 10 and the circulation pipe 12 needs to be closed. The hydraulic oil led out through the infusion pipe 11 can enter the interior of the bottom support assembly 16 through the No. 2 three-way valve 10. When unloading, the one-way valve at the connection between the No. 2 three-way valve 10 and the circulation pipe 12 can be kept open, while the one-way valve at the connection between the No. 2 three-way valve 10 and the infusion pipe 11 is closed. At this time, the No. 2 three-way valve 10 can lead the hydraulic oil from the circulation pipe 12, and reflux it to the interior of the No. 1 three-way valve 9, and finally return to the interior of the liquid storage assembly 13.

[0061] When the movable frame 14 moves upward, the longitudinal guide block 151 moves upward accordingly, and the connecting rod 155 deflects toward the inner side and applies a pulling force to the transverse guide block 152. When the longitudinal guide block 151 moves upward, a pulling force can be applied to the bottom support assembly 16 to drive the bottom support assembly 16 to move upward, and the transverse guide block 152 moves toward the middle of the movable frame 14 accordingly, which can synchronously drive the transverse extension frame 157 and the lateral clamping plate 158 to move toward the middle of the movable frame 14 until one side of the lateral clamping plate 158 contacts the side of the hydrogen fuel cell and applies a force to clamp the hydrogen fuel cell between the two corresponding lateral clamping plates 158. At this time, the two ends of the hydrogen fuel cell can contact the lateral clamping plates 158, and the top end contacts the movable frame 14 to complete the clamping process;

[0062] When the hydraulic oil enters the bottom support assembly 16, the hydraulic oil can be introduced into the temporary storage tube 165 through the exchange tube 169 and exerts a force on the second piston plate 166. At this time, the limit spring 168 is stretched and drives the second piston rod 167 to move away from the exchange tube 169. At this time, the support plate 164 on one side moves toward the middle of the movable frame 14, that is, the two support plates 164 are relatively close to each other. With the upward displacement of the support plate 164, the bottom end of the hydrogen fuel cell placed on the tray can be supported, completing the bottom support process and assisting in the clamping process.

[0063] When the hydrogen fuel cell reaches the designated position and needs to unload materials, the one-way valve at the connection between the second three-way valve 10 and the circulation pipe 12 can be opened. At this time, the limit spring 168 automatically resets, and the hydraulic oil inside the temporary storage pipe 165 can flow back to the second three-way valve 10, be exported through the circulation pipe 12, and then flow back into the inside of the liquid storage pipe 131 through the first three-way valve 9. At this time, the two support plates 164 move away from each other to release the bottom support. At the same time, the movable frame 14 moves downward and drives the support plate 164 to move downward. At the same time, the corresponding lateral clamping plates 158 move away from each other until the hydrogen fuel cell is placed, completing the unloading process.

[0064] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
