Description

Technical Field

[0001] This utility model relates to the technical field of bipolar plate production equipment, and in particular to a gripper robotic arm for a hydrogen production bipolar plate production line. Background Technology

[0002] Against the backdrop of the rapid development of the hydrogen energy industry, hydrogen production bipolar plates, as a core component of fuel cells, directly affect fuel cell performance through their production precision and efficiency. The substrate of hydrogen production bipolar plates often employs a structure where a disc is welded inside a ring. During the production line transfer process, this structure requires a gripper robotic arm for precise movement. Currently, the industry commonly uses magnetic gripper robotic arms to complete the aforementioned transfer operations. The principle behind this is that electromagnets on the grippers are energized to generate magnetism, attracting bipolar plate substrates. However, this type of robotic arm has the following problems: when a sudden power outage occurs at the work site, the electromagnets instantly lose their magnetism, losing their attraction to the workpiece. Furthermore, existing magnetic grippers lack reliable emergency anti-drop structures, allowing the workpiece to fall freely from the grippers. On one hand, the bipolar plate substrate is a high-precision component; falling can easily cause cracks at the welds and surface scratches, directly rendering the workpiece unusable and increasing production costs. On the other hand, falling workpieces may injure operators below, posing a serious safety risk. Utility Model Content

When the drive component is energized, it moves the stop bar away from directly below the electromagnet.

[0015] This application discloses a gripper robotic arm for a hydrogen production bipolar plate production line. (Refer to...) Figure 1 and Figure 2 The gripper robotic arm for hydrogen production bipolar plate production line includes a frame 1, which is composed of several metal rods welded together in a star shape. An electromagnet 2 is installed on the frame 1, with one electromagnet 2 on each metal rod. A flexible component 3 is installed between the frame 1 and the electromagnet 2. A stop bar 4 is installed below the frame 1, located below the electromagnet 2. A drive component 5 is installed on the frame 1. When the drive component 5 is energized, it moves the stop bar 4 away from directly below the electromagnet 2.

[0016] With the cooperation of the drive component 5 and the stop rod 4, when the power is on, the drive component 5 drives the stop rod 4 away from the electromagnet 2. When the power is suddenly cut off, the drive component 5 drives the stop rod 4 to move quickly to directly below the electromagnet 2 and directly receive the workpiece.

[0017] The flexible component 3 includes a mounting base 31, a guide rod 32, a limiting block 33, and a connecting plate 34. The mounting base 31 is connected to the frame 1. The guide rod 32 slides through the mounting base 31. There is one guide rod 32 at each end of the mounting base 31. The limiting block 33 is connected to the top of the guide rod 32. The connecting plate 34 is connected between the bottoms of the two guide rods 32. The electromagnet 2 is connected to the bottom of the connecting plate 34.

[0018] When the gripper arm descends and the electromagnet 2 contacts the workpiece, the electromagnet 2 is subjected to force and can move upward along the direction of the guide rod 32, avoiding hard contact and protecting the workpiece.

[0019] The drive assembly 5 includes a push cylinder 51, a movable block 52, a limit rod 53, a connecting rod 54, a slider 55, and a guide rail 56. The push cylinder 51 is connected to the frame 1, and a mounting plate 11 is connected to the frame 1. The limit rod 53 is vertically mounted on the mounting plate 11, and fixed plates 112 are connected to both ends of the limit rod 53. The fixed plates 112 are connected to the mounting plate 11. The slider 55 is slidably mounted on the limit rod 53, and a through hole is provided on the slider 55 for the limit rod 53 to pass through. The guide rail 56 is connected to the bottom of the mounting plate 11, and the slider 55 is connected to the stop rod 4. The slider 55 is slidably mounted on the guide rail 56. One end of the connecting rod 54 is connected to the movable block 52 by a stepped bolt, and the other end is connected to the stop rod 4 by a stepped bolt.

[0020] Among them, the push cylinder 51 is a one-way cylinder with a built-in elastic component for rebounding the piston rod.

[0021] A spring 531 is fitted on the limiting rod 53, and an installation groove is provided on the movable block 52. One end of the spring 531 abuts against the installation groove, and the other end abuts against the fixed plate 112.

[0022] The drive assembly 5 adopts a combination of "push cylinder 51, spring 531, and connecting rod 54", without a complex electrical control structure, with fast response speed, and the stop rod 4 can be reset immediately after power failure.

[0023] By setting spring 531, the spring force released when the power is off can increase the reset speed of movable block 52, and further increase the moving speed of stop bar 4.

[0024] A support block 111 is connected to the mounting plate 11. The support block 111 is located below the baffle rod 4. The baffle rod 4 slides and fits against the support block 111. The support block 111 supports the baffle rod 4, which helps to improve the stability of the baffle rod 4.

[0025] A rubber pad 41 is attached to the stop rod 4. The rubber pad 41 is located on the upper surface of the stop rod 4. The rubber pad 41 can buffer the contact force between the workpiece and the stop rod 4, further avoid scratches on the workpiece surface, and ensure the production accuracy of the bipolar plate.

[0026] The implementation principle of a gripper robotic arm for a hydrogen production bipolar plate production line according to an embodiment of this application is as follows: 1. Normal power-on operation phase After the equipment is powered on, the cylinder 51 is started, and its piston rod pushes the movable block 52 to move downward along the limit rod 53. At the same time, the movable block 52 compresses the spring 531. The movable block 52 drives the slider 55 to slide along the guide rail 56 via the connecting rod 54. The slider 55 simultaneously drives the stop rod 4 to move away from the direction directly below the electromagnet 2, avoiding the adsorption area of ​​the electromagnet 2. When electromagnet 2 is energized, it generates magnetism and adsorbs the substrate of the hydrogen production bipolar plate. The robotic arm drives the electromagnet 2, which has a workpiece attached, to move to the target station. During the transfer process, the guide rod 32 cooperates with the connecting plate 34 to reduce workpiece shaking.

[0027] 2. Emergency Phase of Sudden Power Outage If a power outage occurs during the transfer process, electromagnet 2 will lose its magnetism, and at the same time, the air pump that drives cylinder 51 will stop working and lose its air pressure support. The spring 531 on the limit rod 53 returns to its original deformation, pushing the movable block 52 to reset upward along the limit rod 53; The movable block 52 pulls the slider 55 to slide in the opposite direction via the connecting rod 54, and the slider 55 drives the stop rod 4 to move quickly to directly below the electromagnet 2; The baffle rod 4 catches the workpiece that has lost its adhesion, and the rubber pad 41 buffers the contact impact to prevent the workpiece from falling or being scratched.

[0028] 3. Reset phase after power restoration After the power supply is restored, the air pump starts working again, pushing the cylinder 51 to push the movable block 52 downward again, and the movable block 52 compresses the spring 531; Link 54 moves the stop rod 4 away from directly below the electromagnet 2 again, avoiding the placement station; After the robotic arm places the workpiece at the target position, the electromagnet 2 is de-energized, and the stop bar 4 remains in a avoidance state, waiting for the next adsorption operation.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of this utility model, and the protection scope of this utility model is not limited to the above embodiments. All technical solutions within the scope of this utility model's concept are within the protection scope of this utility model. It should be pointed out that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
