Description

Technical Field

[0001] This invention relates to the field of hydrogen energy battery lower casing manufacturing, and more particularly to a clean production line system for finished hydrogen energy battery lower casing. Background Technology

[0002] A fuel cell is a power generation device that directly converts the chemical energy present in fuel and oxidant into electrical energy. It is a highly efficient and environmentally friendly new type of power generation device with wide applications in various fields. Hydrogen fuel cells use hydrogen as a chemical element to create energy storage batteries. Because the reaction in a hydrogen fuel cell only produces water, it is a green and environmentally friendly energy source. Hydrogen fuel cells are mainly used in new energy vehicles. The hydrogen fuel cell, the lower casing, and other components together constitute the battery pack, which is the core energy source providing driving power to the entire vehicle. When a new energy vehicle is in operation, the effectiveness of the lower casing in protecting the hydrogen fuel cell is crucial, especially during vehicle vibrations and bumpy rides. In the event of an accident, effectively protecting the hydrogen fuel cell is essential to reducing accident damage and post-accident maintenance costs. Therefore, the lower casing of the hydrogen fuel cell in the battery pack plays a critical role, affecting the normal operation and lifespan of the battery pack. It is also a safety component of the new energy vehicle battery pack and influences the working and discharge performance of the hydrogen fuel cell. The lower casing of the hydrogen fuel cell is an important component of the fuel cell, strengthening its structural performance during use, preventing accidental impacts, and serving to support and protect the fuel cell.

[0003] Research on the lower casing of hydrogen fuel cells has always been a crucial aspect of fuel cell applications. For example, Chinese patent (application number: 201910772533.4) discloses a lower casing for a power battery and its manufacturing method. The method includes: S1, cutting fiber sheets according to the unfolded diagram of the casing structure; S2, laying fiber sheets layer by layer on the surface of a pre-made mold corresponding to the shape of the inner cavity of the lower casing to form a first composite layer; S3, aligning and pressing a pre-formed metal frame into a preset groove in the mold and pressing it onto the first composite layer; S4, laying fiber sheets layer by layer on the surfaces of the first composite layer and the metal frame to form a second composite layer; S5, closing the mold and transferring it into a vacuum environment, and filling the mold with resin; S6, transferring the resin-filled mold from the vacuum environment into a curing oven and curing it under controlled temperature. This patent primarily uses composite materials and resin to make the lower casing. In addition, some lower casings may use metal materials. The finished product of the hydrogen fuel cell lower casing (such as a preliminary product made from a mixture of metal, composite materials, and resin, which requires cleaning) generates a significant amount of waste during manufacturing (mostly due to cutting, welding, and bonding processes). This waste adheres to the lower casing and is difficult to remove, especially from the corners and connecting edges. Existing technologies mostly rely on manual observation and targeted cleaning, which is labor-intensive, ineffective, and prone to causing injuries to workers, resulting in low efficiency. With the surge in demand for hydrogen fuel cells and their trend towards mass production, there is an urgent need for a mechanized, assembly-line system for cleaning hydrogen fuel cell lower casings to meet the needs of multi-station assembly line processing. Summary of the Invention

[0004] The purpose of this invention is to solve the technical problems pointed out in the background art and provide a cleaning production line system for finished hydrogen energy battery lower casings. The system achieves a streamlined transport of the finished hydrogen energy battery lower casings within the washing shell section, passing through a coarse bleaching station, a coarse washing station, a fine bleaching station, and a fine washing station, performing multi-station cleaning processes sequentially. Then, a station transfer device transfers the finished hydrogen energy battery lower casings from the fine washing station to the air-drying station inside the drying shell section. Within the drying shell section, the system performs a streamlined transport of the finished hydrogen energy battery lower casings through an air-drying station, a drying station, and a cooling station, performing water removal, chip removal, drying, and cooling processes sequentially. This improves the washing, cleaning, drying, and cooling effects, facilitating large-scale production and batch, streamlined operation of hydrogen energy batteries and lower casings.

[0051] In some embodiments, such as Figures 2-4 As shown, the feeding and pushing mechanism A2 includes a combined support 21, a tilting frame 24, and a lifting cylinder A25. A shaft 22 is fixed to the first side of the top of the combined support 21, and a support beam 23 is fixed to the second side of the top of the combined support 21. The first side of the tilting frame 24 is rotatably mounted on the shaft 22, and the second side of the tilting frame 24 corresponds to the support beam 23. The lifting cylinder A25 is located inside the combined support 21 and has a lifting rod A251. The bottom of the tilting frame 24 is provided with a limiting groove 210, which is arranged in a straight line from the first side to the second side of the tilting frame 24. A hinge slider 211 is slidably mounted in the limiting groove 210, and the end of the lifting rod A251 is hinged to the hinge slider 211. Several shifting rollers 26 are rotatably mounted on the tilting frame 24, and a motor 27 is fixed on the tilting frame 24. The motor 27 drives all the shifting rollers 26 to rotate synchronously through a linkage mechanism.

[0052] In some embodiments, the linkage mechanism includes a drive chain 28 and a synchronization chain 29. A sprocket A261 is fixed to the end of each shifting roller component 26. All sprockets A261 of the shifting roller components 26 are poweredly connected via the synchronization chain 29. One shifting roller component 26 also has a drive sprocket A fixed to its end. A drive sprocket B is fixed to the shaft of the motor 27, and drive sprocket B is poweredly connected to drive sprocket A via the drive chain 28.

A baffle 242 is provided on the front side of the flipping frame 24. The material discharge and receiving mechanism B37 of the present invention has the same structure as the material feeding and pushing mechanism A2.

[0053] The present invention also includes a production line control system, which includes a feeding control module A, a water washing and cleaning control module, a transfer control module, a drying control module, and a receiving control module B. The feeding control module A is connected to the motor 27 and the lifting cylinder A25 of the feeding and pushing mechanism A2, respectively. The feeding control module A controls the lifting cylinder A25 to drive the tilting frame 24 to tilt (for example, tilt 30 degrees), and controls the motor 27 to drive all the shifting rollers 26 to rotate, thereby realizing the tilting and tilting of the hydrogen energy battery lower box finished product 15 and its movement toward the coarse bleaching station 4. Specifically, the hoisting device (generally a vacuum adsorption hoisting device) hoists the finished hydrogen energy battery lower casing 15 to the top of the flipping frame 24. At this time, the flipping frame 24 is in its original horizontal position. After the finished hydrogen energy battery lower casing 15 is placed on the flipping frame 24, each cleaning station of the cleaning production line system of the present invention is arranged at an angle (for example, at a 30-degree angle). When the finished hydrogen energy battery lower casing 15 is input, the lifting cylinder A25 drives the lifting rod A251 to move upward. The end of the lifting rod A251 realizes the flipping frame 24 to flip at a certain angle (for example, at a 30-degree angle). The end of the lifting rod A251 is hinged to the hinge slider 211. The hinge slider 211 is slidably installed in the limiting slide groove 210. In this way, when the flipping frame 24 flips, the hinge slider 211 can adapt and move accordingly. Then, motor 27 drives one of the shifting rollers 26 to rotate via drive chain 28, and then drives all the shifting rollers 26 to rotate via synchronous chain 29. In this way, all the shifting rollers 26 on the tilting frame 24 rotate synchronously and drive the hydrogen energy battery lower box assembly 15 to rotate according to the specified parameters. Figure 2 The hydrogen fuel cell lower casing finished product 15 is transported from front to back in the direction of the transport movement, thus transporting it into the clean production line operation system of the present invention.

[0054] The water washing and cleaning control module of this invention is connected to the rinsing centrifugal pump 8, the clean water centrifugal pump 9, the drive motor A, and the drive motor B respectively. The water washing and cleaning control module controls the drive motor A and the drive motor B to move synchronously and realize the synchronous rotation of all shifting rollers A411, all shifting rollers B511, all shifting rollers C611, and all shifting rollers D711, so as to realize the hydrogen energy battery lower box finished product 15 flowing through the coarse rinsing station 4, the coarse washing station 5, the fine rinsing station 6, and the fine washing station 7 in sequence. The water washing and cleaning control module controls the rinsing centrifugal pump 8 and the clean water centrifugal pump 9 to start working respectively. Each rinsing nozzle A of the coarse rinsing station 4 sprays rinsing water. After the hydrogen energy battery lower box finished product 15 is transported to the coarse washing station 5, each spray nozzle A141 of the coarse washing station 5 sprays high-pressure cleaning water for rinsing. After the hydrogen energy battery lower box finished product 15 is transported to the fine rinsing station 6, each rinsing nozzle B of the fine rinsing station 6 sprays rinsing water. After the hydrogen energy battery lower box finished product 13 is transported to the fine washing station 7, each spray nozzle B of the fine washing station 7 sprays high-pressure cleaning water for rinsing. The finished hydrogen energy battery lower casing 15 is transported along an assembly line and passes through the coarse bleaching station 4, coarse washing station 5, fine bleaching station 6, and fine washing station 7 in sequence. Cleaning treatment is carried out at each of these stations, enabling batch and mechanized cleaning of the finished hydrogen energy battery lower casing 15. This facilitates large-scale production and batch, streamlined operation of hydrogen energy batteries and lower casings.

[0055] The transfer control module of this invention is connected to the lifting cylinder B18, the lifting conveyor 20, the conveyor lifting cylinder, the lifting cylinder C36, the drive motor E, and the drive motor F. The transfer control module controls the lifting cylinder B18 to drive the front station receiving rotating frame 16 to rotate and tilt (e.g., tilt 30 degrees), and controls the drive motor E to drive all the transverse moving rollers A19 on the front station receiving rotating frame 16 to rotate, thereby transporting the finished hydrogen energy battery lower box body 15 located at the fine washing station 7 to the front station receiving rotating frame 16. Then, the lifting cylinder B18 is controlled to drive the front station receiving rotating frame 16 to return to the horizontal position, and the conveyor lifting cylinder is controlled to drive the lifting conveyor 20 to rise to a certain height and lift the finished hydrogen energy battery lower box body 15. The lifting conveyor 20 is controlled to work and transport the finished hydrogen energy battery lower box body 15 to the rear station conveying rotating frame 32. The transfer control module controls the lifting conveyor 20 to descend, reset, and stop working. The transfer control module controls the lifting cylinder C36 to drive the rear station material conveying rotating frame 32 to flip and tilt (e.g., tilt 30 degrees), and controls the drive motor F to drive all the transverse moving rollers B33 on the rear station material conveying rotating frame 32 to rotate, thereby realizing the transportation of the finished hydrogen energy battery lower box body 15 located on the rear station material conveying rotating frame 32 to the first air drying station 38. Then, it controls the lifting cylinder C36 to make the rear station material conveying rotating frame 32 flip and return to the horizontal position.

[0056] The drying control module of this invention is connected to the first fan 46, the second fan 47, the dryer 48, the drive motor C, and the drive motor D. The drying control module controls the drive motor C and the drive motor D to move synchronously and realize the synchronous rotation of all rollers A, B, C, and D, so that the finished hydrogen energy battery lower casing 15 can be processed sequentially in the first drying station 38, the second drying station 39, the drying station 40, and the cooling station 49. High-pressure air is blown out from each air outlet A of the first drying station 38 to form air knives for dehydration and descaling. After the finished hydrogen energy battery lower casing 15 is transported to the second drying station 39, high-pressure air is blown out from each air outlet B of the second drying station 39 to form air knives for dehydration and descaling. After the finished hydrogen fuel cell lower casing 15 is transported to the drying station 40, hot air is blown out from each hot air outlet of the drying station 40 for drying. After the finished hydrogen fuel cell lower casing 15 is transported to the cooling station 40, cold air is blown out from each cold air outlet of the cooling station 40 for cooling. The finished hydrogen fuel cell lower casing 15 is transported in an assembly line and passes through the first drying station 38, the second drying station 39, the drying station 40, and the cooling station 49 in sequence. It undergoes water removal, chip removal, drying, and cooling processes at the first drying station 38, the second drying station 39, the drying station 40, and the cooling station 49, respectively. This realizes the batch and mechanized cleaning process of the finished hydrogen fuel cell lower casing 15, which facilitates the large-scale production and batch, assembly line operation of hydrogen fuel cells and lower casings.

[0057] The receiving control module B is connected to the discharge receiving mechanism B37. The discharge receiving mechanism B37 has the same structure as the feeding and pushing mechanism A2. After the hydrogen energy battery lower box body finished product 15 is cooled, it is flipped and tilted by the discharge receiving mechanism B37 to receive the material and then placed horizontally. Then it waits for the hoisting device to lift it away. Then the discharge receiving mechanism B37 flips and tilts and waits for the material to be received.

[0058] This invention enables automated transport within the water-washing housing section, passing through a coarse bleaching station 4, a coarse washing station 5, a fine bleaching station 6, and a fine washing station 7, where multiple cleaning processes are performed sequentially. Then, a station transfer device transfers the finished hydrogen energy battery lower casing 13 from the fine washing station 7 to the air-drying station (mainly the first air-drying station 38) inside the drying housing section. Within the drying housing section, automated transport passes through an air-drying station, a drying station 40, and a cooling station 41, where water removal, shavings removal, drying, and cooling processes are performed sequentially. This improves the water washing, cleaning, drying, and cooling effects, facilitating large-scale production and batch, automated operation of hydrogen energy batteries and their lower casings.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
