DETAILED DESCRIPTION OF THE INVENTION

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1

[0029] Please refer to Figures 1 to 3 , which is the first embodiment of the present invention. This embodiment provides a technical solution: an automated manufacturing method for high-pressure components for hydrogen energy storage, including the following steps:

[0030] Step 1: Material pretreatment. Feed the carbon fiber composite material into a high-precision laser cutting machine and cut it into appropriate sizes and shapes according to the design requirements. During the cutting process, the cutting machine uses laser positioning technology to ensure that the cutting accuracy reaches ±0.1 mm. Feed the cut composite material into an ultrasonic cleaning machine and clean it with ultrasonic waves at a frequency of 40 kHz to remove impurities such as oil stains and dust on the surface. The cleaning time is 10 minutes. Feed the cleaned composite material into a drying oven for drying treatment. The drying temperature is 60°C to ensure the stability of the material in subsequent processes.

[0031] Step 2: Laying and winding. Feed the pretreated composite material into a wet winding machine and perform laying or winding operations according to the design requirements. The winding machine is equipped with high-precision sensors and a control system, which can monitor the laying thickness and winding angle in real time to ensure the uniformity and accuracy of laying or winding. The laying thickness is 0.2 mm, the winding angle is ±45°, and the winding speed is 10 m / min. During the laying or winding process, the control system precisely controls the composite material according to the preset parameters to ensure that the thickness and angle of each layer or each turn are consistent.

[0032] Step 3: Curing and forming. Feed the laid or wound high-pressure component into a hot pressing and curing furnace for heating and curing. The curing furnace is equipped with a temperature sensor, a pressure sensor, and a time controller, which can monitor the temperature, pressure, and time during the curing process in real time. During the curing process, the control system precisely controls the curing furnace according to the preset parameters of a curing temperature of 120°C, a curing pressure of 5 MPa, and a curing time of 2 hours to ensure the stability and consistency of the curing process.

[0033] Step 4: Non-destructive testing and testing. The cured high-voltage component is detected using an ultrasonic detector and an X-ray detector. The frequency of the ultrasonic detector is 20 MHz, which can detect minute defects inside the high-voltage component; the voltage of the X-ray detector is 100 kV, which can penetrate the wall thickness of the high-voltage component to detect its internal structure and defects. The high-voltage component is subjected to a pressure test, and the test pressure is 1.5 times the working pressure. The pressure testing machine can monitor the deformation and leakage of the high-voltage component under pressure in real time to ensure that the pressure-bearing capacity of the high-voltage component meets the design requirements.

[0034] Step 5: Post-treatment. Post-treatment steps such as cutting, grinding, and cleaning are performed on the qualified high-voltage components after testing. The cutting machine uses laser cutting technology to ensure that the cutting accuracy reaches ±0.2 mm; the grinding machine uses a fine grinding process to ensure that the surface roughness Ra of the high-voltage component is <0.8 μm; the cleaning machine uses a high-pressure water gun and cleaning agent for cleaning to ensure the surface cleanliness of the high-voltage component. Final inspection and packaging are carried out on the post-treated high-voltage components, and they are ready for shipment. The inspection content includes appearance inspection, dimension measurement, performance testing, etc., to ensure that the quality of the high-voltage component meets the design requirements.

For details, reference can be made to the existing patent with the publication number CN111421242B, and no further elaboration will be provided here. And a material to be cut 4 is placed on the top of the cutting machine table 1;

[0037] And two adjustable limit mechanisms 5 provided on the top of the cutting machine table 1, including an L-shaped base 51 slidably arranged on the top surface of the cutting machine table 1, and a movable pressing plate 53 rotatably installed on the top of the L-shaped base 51. The end of the movable pressing plate 53 is above the material to be cut 4, and a pressing assembly is provided.

[0038] In this embodiment, preferably, the pressing assembly includes a movable rod 541 movably penetrating through the end of the movable pressing plate 53, a pressing block 543 fixed on the bottom surface of the movable rod 541, an anti-slip pressing pad 544 adhesively fixed to the bottom surface of the pressing block 543, a first spring 542 sleeved on the bottom end of the movable rod 541 and located between the pressing block 543 and the movable pressing plate 53, and a top block 545 fixed on the top end of the movable rod 541 and located on the top of the movable pressing plate 53. The anti-slip pressing pad 544 is made of rubber material. Subsequently, under the pushing of the first spring 542, the anti-slip pressing pad 544 can be stably pressed on the top of the material to be cut 4, playing a role of pressing and limiting the material to be cut 4, ensuring the stability of the material to be cut 4 during the subsequent cutting process, and ensuring the cutting accuracy.

[0039] In this embodiment, preferably, the bottom end of the first spring 542 abuts against the top surface of the pressing block 543, and the top end of the first spring 542 abuts against the bottom surface of the movable pressing plate 53.

[0040] In this embodiment, preferably, a shaft seat 56 is fixed on the top surface of the L-shaped base 51, and the movable pressing plate 53 is rotatably sleeved on the surface of the shaft seat 56, so that the movable pressing plate 53 can rotate on the top of the L-shaped base 51, facilitating the rotation and adjustment of the pressing position of the pressing assembly on the material to be cut 4.

[0041] In this embodiment, preferably, a T-shaped slider 52 is welded and fixed on the bottom surface of the L-shaped base 51, and a T-shaped chute 11 corresponding to the T-shaped slider 52 is formed on the top surface of the cutting machine table 1. The T-shaped slider 52 is slidably located in the T-shaped chute 11, so that the position of the L-shaped base 51 can be slidably adjusted subsequently.

[0042] Embodiment 2

[0043] Please refer to Figures 1 to 5, which is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The difference is that a limiting component is provided on one side of the L-shaped base 51. The limiting structure includes a C-shaped movable seat 551 movably installed on the side surface of the L-shaped base 51, and a limiting clamping rod 552 welded and fixed to the bottom surface of the C-shaped movable seat 551. A plurality of limiting slots 12 corresponding to the limiting clamping rod 552 are opened on the top surface of the cutting machine table 1 relative to one side of the T-shaped sliding groove 11. The bottom end of the limiting clamping rod 552 is inserted into one of the limiting slots 12, which can stably limit the L-shaped base 51 during daily use. A side sliding groove 553 is opened on the side surface of the L-shaped base 51, and a side sliding block 555 is slidably arranged in the side sliding groove 553. One end of the side sliding block 555 extends out of the side surface of the L-shaped base 51 and is fixed to the C-shaped movable seat 551, so that the C-shaped movable seat 551 can smoothly slide up and down on the side surface of the L-shaped base 51. A second spring 554 is also arranged in the side sliding groove 553, and a guide rod 556 is vertically fixed in the side sliding groove 553. Both the second spring 554 and the side sliding block 555 are sleeved on the surface of the guide rod 556, so that the side sliding block 555 can be guided and limited when sliding up and down. The second spring 554 is located at the top of the side sliding block 555. When it is necessary to adjust the position of the adjustable limiting mechanism 5 later, only need to lift the C-shaped movable seat 551, so that the side sliding block 555 slides up and compresses the second spring 554, causing the bottom end of the limiting clamping rod 552 to move out of the limiting slot 12, and then the L-shaped base 51 can be no longer limited. At this time, the L-shaped base 51 can be slid back and forth to change the positions of the movable pressing plate 53 and the pressing component. When adjusted to the appropriate position, release the C-shaped movable seat 551. Under the pushing of the second spring 554, the side sliding block 555 drives the C-shaped movable seat 551 to move down and reset, and finally the bottom end of the limiting clamping rod 552 is inserted into the limiting slot 12 at other positions, and then the L-shaped base 51 can be limited again, completing the adaptive adjustment of the position of the adjustable limiting mechanism 5, which is convenient for pressing and limiting different positions of the material 4 to be cut.

[0044] Although the embodiments of the present invention have been shown and described (see the above detailed description), 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 principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
