Description

Technical Field

[0001] This utility model relates to the technical field of bipolar plate production and processing equipment, and in particular to a pad placement device for stacking hydrogen production bipolar plates. Background Technology

[0002] In the field of hydrogen production equipment core component manufacturing, bipolar plates are a key component of fuel cells, and their processing precision and surface quality directly affect battery performance. After bipolar plates are machined into circular substrates, they need to be stacked for transfer or storage. To avoid surface scratches and edge damage caused by direct contact and friction between adjacent circular substrates, the industry generally adopts the protective method of placing flexible gaskets (such as rubber pads or silicone pads) between adjacent circular substrates or between the transfer station and the first circular substrate.

[0003] Currently, this protective operation relies on manual labor: workers need to pick up the pads one by one and place them at 3-4 points distributed around the circular substrate. Each placement takes about 15 seconds, and stacking a set of bipolar substrates takes a lot of time. In mass production scenarios, this becomes an efficiency bottleneck in the transfer process. Moreover, each bipolar circular substrate is relatively heavy. When placing the pads manually, the hands need to be placed under the ring or in the area to be stacked. If the ring is not placed stably and tilts or falls, it is very easy to cause hand injuries or crush injuries, posing a high safety risk. Utility Model Content

[0004] In order to improve the method of manually placing the pads and increase the efficiency and safety of pad placement, this application provides a pad placement device for stacking hydrogen production bipolar plates.

The transfer platform has a lifting platform inside, a lifting assembly is mounted on the base, a guide pipe is connected to the transfer platform, the height of the guide pipe is equal to the thickness of a single gasket, several guide pipes are evenly spaced along the circumference of the transfer platform, a storage bin is connected to the upper surface of the guide pipe, the storage bin is in communication with the guide pipe, a pusher plate is slidably mounted inside the guide pipe, the pusher plate has material holes adapted to the gaskets, a pusher assembly is mounted on the transfer platform, and a discharge pipe is connected to the lower surface of the guide pipe, the discharge pipe is in communication with the guide pipe, and the discharge pipe extends obliquely to the transfer platform.

[0006] Preferably, a telescopic rod is connected between the base and the lifting platform. The telescopic rod is arranged vertically, and several telescopic rods are arranged at equal intervals along the circumference of the lifting platform.

[0007] Preferably, a photoelectric sensor is connected to the lifting platform, and the photoelectric sensor is located at the center of the lifting platform. The photoelectric sensor is used to detect the robotic arm that grips the workpiece above.

[0008] Preferably, a guide roller is connected inside the discharge pipe, and a connecting hole is provided on the discharge pipe for the roller shaft of the guide roller to pass through. The guide roller is located on the lower surface of the discharge pipe, and several guide rollers are arranged at equal intervals along the length of the discharge pipe.

[0009] Preferably, the storage silo is provided with an observation port, which is located on the side wall of the storage silo and is arranged along the height direction of the storage silo.

[0016] This application discloses a pad placement device for stacking bipolar plates in hydrogen production. (Refer to...) Figure 1 , Figure 2 and Figure 3 The device for stacking bipolar plates for hydrogen production includes a base 1, a transfer platform 2 set on the base 1, the platform surface of the transfer platform 2 is arranged in a ring shape, a lifting platform 3 is set inside the transfer platform 2, and a lifting assembly 11 is set on the base 1. The lifting assembly 11 is a high-precision cylinder, the cylinder body of the high-precision cylinder is connected to the base 1, and the piston rod is connected to the bottom of the lifting platform 3.

[0017] A guide pipe 21 is connected to the transfer station 2. The height inside the guide pipe 21 is equal to the thickness of a single gasket, ensuring that each discharge is of a single gasket. Several guide pipes 21 are evenly distributed along the circumference of the transfer station 2, enabling simultaneous feeding from multiple points. A storage bin 22 is connected to the upper surface of the guide pipe 21, and the storage bin 22 is interconnected with the guide pipe 21. A pusher plate 23 is slidably installed inside the guide pipe 21, and the pusher plate 23 has a material hole 231 adapted to the gasket. A pusher assembly 24 is installed on the transfer station 2. The pusher assembly 24 is a pusher cylinder, and the piston rod of the pusher cylinder is interconnected with the pusher plate 23. A discharge pipe 25 is connected to the lower surface of the guide pipe 21, and the discharge pipe 25 is interconnected with the guide pipe 21. The discharge pipe 25 extends obliquely to the transfer station 2, and the discharge pipe 25 is as close as possible to the inner ring of the circular ring, but does not affect the placement of the bipolar plate substrate.

[0018] By storing pads in batches through the storage bin 22, the material guide pipe 21, the pusher plate 23, the pusher assembly 24 and the discharge pipe 25 work together to automatically feed materials at multiple points, replacing manual point-by-point placement operations, improving the material feeding speed, and eliminating the need for manual hand placement under the bipolar plates or in the stacking area, thus avoiding hand injuries or crushing injuries caused by the bipolar plates tilting or falling.

[0019] A telescopic rod 12 is connected between the base 1 and the lifting platform 3. The telescopic rod 12 is set in the vertical direction, and several telescopic rods 12 are arranged at equal intervals along the circumference of the lifting platform. The installation of the telescopic rod 12 helps to improve the stability of the lifting platform during the lifting process.

[0020] A photoelectric sensor 4 is connected to the lifting platform 3. The photoelectric sensor 4 is located at the center of the lifting platform 3. The photoelectric sensor 4 is used to detect the robotic arm that grabs the workpiece above. The photoelectric sensor 4 links the robotic arm with the pushing and lifting actions, which can be integrated into the bipolar plate automated production line without manual intervention, thus improving the automation integration of the overall production process.

[0021] A guide roller 5 is connected inside the discharge pipe 25. The discharge pipe 25 has a connecting hole for the roller shaft of the guide roller 5 to pass through. The guide roller 5 is located on the lower surface of the discharge pipe 25. Several guide rollers 5 are arranged at equal intervals along the length of the discharge pipe 25. The guide roller 5 improves the sequential movement of the gasket in the discharge pipe 25 and avoids the gasket getting stuck in the discharge pipe 25.

[0022] An observation port 221 is provided on the storage bin 22. The observation port 221 is located on the side wall of the storage bin 22 and is set along the height direction of the storage bin 22. By setting the observation port 221, it is convenient for operators to observe the number of gaskets in the storage bin 22 and to replenish the material in a timely manner.

[0023] The implementation principle of the gasket placement device for stacking hydrogen production bipolar plates in this application is as follows: 1. Preliminary preparation stage Add sufficient flexible pads, such as rubber pads or silicone pads, into the storage bin 22. After the pads are naturally stacked, the bottom single pad falls into the material hole 231 of the pusher plate 23, completing the material supply preparation. Adjust the equipment parameters to ensure that the lifting stroke of the high-precision cylinder in the lifting assembly 11 matches the thickness of the bipolar plate substrate, and that the sensitivity of the photoelectric sensor 4 meets the detection requirements of the robotic arm.

[0024] 2. Detection and Triggering Phase When the robotic arm that grips the bipolar plate moves above the transfer platform 2, the photoelectric sensor 4 at the center of the lifting platform 3 detects the signal from the robotic arm and simultaneously triggers the pusher assembly 24 and the lifting assembly 11 to start.

[0025] 3. Gasket Pushing and Conveying Stage The pusher assembly 24 drives the pusher plate 23 to slide along the guide tube 21. When the material hole 231 of the pusher plate 23 moves to the inlet of the discharge tube 25, the gasket in the material hole 231 falls into the discharge tube 25 under the action of gravity. The gasket slides in the inclined direction inside the discharge pipe 25. With the help of the guide roller 5 inside the pipe, it lands smoothly on the platform of the transfer table 2 during the first stacking, and then lands on the already stacked bipolar plate substrate, completing the automatic placement of a single gasket at multiple points.

[0026] 4. Lifting platform adjustment stage 3 After the pad is placed, the pusher assembly 24 drives the pusher plate 23 to reset, and the next pad in the storage bin 22 automatically falls into the material hole 231 of the pusher plate 23, waiting for the next feeding. Meanwhile, the high-precision cylinder in the lifting assembly 11 pushes the lifting platform 3 to rise, and the rising height is consistent with the thickness of a single bipolar plate substrate, reserving suitable space for the stacking of the next bipolar plate and the placement of the pad.

[0027] 5. Full load and reset phase Repeat the steps multiple times until the bipolar plates on the transfer station 2 are stacked to the preset number, at which point the station is fully loaded. Once fully loaded, the lifting assembly 11 lowers the lifting platform 3 to its initial position. Workers or automated equipment then transfer the entire stack of bipolar plates, and the device returns to its initial state, awaiting the next round of stacking operations.

[0028] 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.
