[0020] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0021] Since most existing installation methods rely on manual assembly, the pressure on the sealing ring is unbalanced when the bolts are tightened manually during assembly. This causes the sealing ring to deform and fail to completely fill the gaps, resulting in poor sealing performance. This allows the gas to remain connected to the outside, which can easily lead to malfunctions in the energy storage system.

[0022] Therefore, in view of the above-mentioned problems, the present invention discloses an automated processing and assembly device for an energy storage exhaust valve core, with reference to... Figures 1-3As shown, the device includes a base 100. A pair of opposing support vertical plates 101 are detachably connected to the upper surface of one side of the base 100. Mounting platforms 102 are detachably connected to the outer walls of the support vertical plates 101. A telescopic cylinder 201 is detachably connected to the upper end of the mounting platform 102. The telescopic end of the telescopic cylinder 201 passes through the mounting platform 102 and is detachably connected to a U-shaped plate 200 with its opening facing downwards. A limiting support platform 300 is provided at the upper end of the base 100, directly below the U-shaped plate 200. A valve seat support frame 301 is provided on the valve body base, which is inserted into the valve seat support frame 301. In this embodiment, the assembly after the valve core and the sealing cover are connected is clamped on the U-shaped plate 200. Then, the telescopic cylinder 201 is activated to extend, so that the U-shaped plate 200 falls and fits the assembly with the valve body base. As the telescopic cylinder 201 extends, pressure is applied to squeeze the sealing ring, so that the pressure on the sealing ring is more uniform. Then, the bolts are tightened to fix it, which makes the sealing effect better and more convenient when tightening the bolts, without the need to manually squeeze the valve body base and the sealing cover.

[0023] Since the assemblies need to be manually installed under the U-shaped plate 200, this greatly reduces installation efficiency. In order to automatically snap the assemblies onto the U-shaped plate 200, the specific structure can be as follows: Figures 1-4 In the embodiment shown, the opposite surfaces of the two supporting vertical plates 101 are detachably connected to a feeding conveyor belt 103. The outer wall of the sealing cover contacts the feeding conveyor belt 103, and the valve core hangs naturally between the two feeding conveyor belts 103. The U-shaped plate 200 has two opposing clamping conveyor belts 202 on both sides inside. The outer wall of the U-shaped plate 200 is equipped with a first servo motor 203, which drives the clamping conveyor belts 202 to rotate. In this embodiment, the assembly is conveyed towards the U-shaped plate 200 by rotating the feeding conveyor belt 103. The clamping conveyor belts 202 on both sides are aligned with the upper end of the feeding conveyor belt 103. As the assembly is conveyed, the sealing cover on the assembly is stuck between the two clamping conveyor belts 202 on the left and right sides. The assembly can be held in place by the opposing clamping conveyor belts 202. When the telescopic cylinder 201 extends, the assembly can be moved downward with the U-shaped plate 200, and the valve core can be inserted between the valve body base.

[0024] To facilitate the positioning of the assembly card inside the clamping conveyor belt 202, the specific structure can be as follows: Figure 4In the embodiment shown, a limit baffle 204 is rotatably connected to the outer wall of the U-shaped plate 200 away from the feeding conveyor belt 103 by a torsion spring. The limit baffle 204 is provided with left and right opposite touch buttons 205, which are located between opposite clamping conveyor belts 202. In this embodiment, after the assembly enters the interior of the U-shaped plate 200, it sends a signal after contacting the touch button 205, and the first servo motor 203 and the feeding conveyor belt 103 stop rotating, thereby enabling precise positioning of the assembly. Through the torsion spring rotatable connection of the limit baffle 204, after the assembly is connected to the valve body base, the limit baffle 204 can be pushed open by the continued rotation of the clamping conveyor belt 202, thereby allowing the installed exhaust valve to be removed.

[0025] Because the telescopic cylinder 201 makes a hard contact with the valve body base inside the valve seat support 301 when it extends, the pressure applied to the sealing ring by the extension of the telescopic cylinder 201 increases rapidly after contact. This can easily cause deformation of the assembly or the sealing ring, resulting in poor sealing performance. In order to allow the telescopic cylinder 201 to extend slowly and apply pressure to the sealing ring, the specific structure can be as follows: Figure 5 In the illustrated embodiment, the bottom sides of the valve seat support frame 301 are detachably connected to the telescopic ends of the elastic telescopic rod 302. The base of the elastic telescopic rod 302 is detachably connected to the upper end of the equipment base 100. The valve seat support frame 301 is slidably connected to the limiting support platform 300. The elastic telescopic rod 302 extends outward in normal state. In this embodiment, when the telescopic cylinder 201 extends and drives the assembly to fit against the valve body base inside the valve seat support frame 301, the valve seat support frame 301 will move downward. During the movement, the elastic telescopic rod 302 is compressed, so that the resistance of the elastic telescopic rod 302 gradually increases. This allows the force applied to the sealing ring when pressing down to be applied slowly, avoiding the pressure from rising too quickly and causing deformation or damage to the assembly, valve body base, or sealing ring.

[0026] If the bolts are tightened manually during the compression phase, excessive manual intervention is required, resulting in low automation. To automatically tighten the bolts after compression, a specific structure can be adopted as follows: Figures 5-8In the embodiment shown, the upper end of the valve seat support frame 301 is located opposite the valve body base and the threaded hole of the sealing cover, and is provided with a through hole 303. Four sliding bases 400 are rotatably connected to the upper end of the equipment base 100 inside the two side support vertical plates 101. The sliding bases 400 are positioned opposite the through holes 303. Each sliding base 400 has a secondary meshing gear 401 fixedly connected to its outer wall near the bottom. A sliding rod 402 is provided at the upper end of each sliding base 400, and a bolt slot 404 is provided at the top of the sliding rod 402. A second servo motor 304 is detachably connected to the bottom of the equipment base 100. The second servo motor 304 passes through the equipment base 100 and is detachably connected to a main drive gear 305. 305 meshes with each secondary meshing gear 401. In this embodiment, the second servo motor 304 rotates to drive the main drive gear 305 to rotate, which in turn drives each secondary meshing gear 401 to rotate, thereby driving each sliding base 400 and sliding rod 402 to rotate. When the telescopic cylinder 201 extends, the bolt head is inserted into the through hole 303 and locked in the bolt slot 404. When the valve seat support frame 301 is pressed down, the bolt is inserted into the threaded hole of the valve body base and the sealing cover, and tightened by rotation. This allows all bolts to be tightened while keeping the sealing ring under pressure, so that the tightening force of each bolt is the same, further ensuring the uniformity of the compression deformation of the sealing ring, resulting in a better sealing effect.

[0027] As the bolt is tightened, it may move upwards and disengage from the bolt catch 404, making it impossible to tighten. To avoid this, a specific structure can be adopted as follows: Figure 7 In the embodiment shown, the sliding rod 402 is slidably connected to the interior of the sliding base 400. The sliding rod 402 is provided with a plurality of limiting grooves 403. The inner wall of the sliding base 400 is provided with a slider that inserts into the limiting grooves 403. A return spring 405 is fixedly connected to the bottom of the sliding rod 402. In this embodiment, the sliding rod 402, in conjunction with the slider, can drive the bolt to rotate and tighten while the sliding rod 402 slides. The return spring 405 can apply pressure to the bolt as the bolt is tightened, thereby ensuring that the bolt is fully tightened.

[0028] After the assembly is fixed to the valve body base, the airtightness of the exhaust valve needs to be tested. To achieve airtightness testing on a single machine, the specific structure can be as follows: Figure 8In the embodiment shown, an air inlet pipe 500 is detachably connected to the bottom inner side of the valve seat support frame 301. The end of the air inlet pipe 500 is connected to an air compressor. An electromagnetic three-way valve 501 is detachably connected to the air inlet pipe 501. In this embodiment, air is injected into the interior of the valve seat support frame 301 by the air compressor and enters the interior of the exhaust valve. By observing the change in air pressure, it can be determined whether the exhaust valve is sealed. By adjusting the electromagnetic three-way valve 501, pressure can be released, thereby enabling a sealing test on each assembled exhaust valve, resulting in a higher yield rate after assembly.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
