It may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0026] Reference Figure 2 , Figure 2 This invention provides a flowchart of a method for capping a gas cylinder; the method for capping a gas cylinder according to embodiments of the invention may include, but is not limited to, steps S100, S200, S300, S400, and S500: Step S100: After the cap delivery module 300 places the caps on a group of gas canisters to be capped, a first gas canister is obtained. The group of gas canisters to be capped includes a first number of gas canisters to be capped.

[0027] Step S200: After the first gas tank is evacuated once by the vacuum module, the second gas tank is obtained. Step S300: The position detection result is obtained after the detection module 500 detects the position of the placement label and gas cap on the second gas cylinder. Step S400: Based on the position detection result, control the calibration module 600 to rotate the gas cap on the second gas canister so that the label and the limiting notch 801 on the gas cap are rotated to a preset relative position to obtain the third gas canister. Step S500: The target gas tank is obtained by performing a second vacuuming on the third gas tank through the vacuuming module.

[0028] It should be noted that, referring to Figure 3 and Figure 4 The rotary feeding module of this application serves as the conveying carrier between the modules, responsible for smoothly and uniformly transferring the gas canisters (including the gas canister to be capped, the first gas canister, the second gas canister, the third gas canister, and the target gas canister) between the cap conveying module 300, the vacuuming module, the detection module 500, and the calibration module 600, ensuring the orderly connection of each process; the cap conveying module 300, the vacuuming module, the detection module 500, and the calibration module 600 are arranged around the base 100. Specifically, this application also includes a feeding module 200 and a discharging module 210. The feeding module 200 is used to transport the gas canister to be capped to the rotary feeding module. The rotary feeding module transports the gas canister to be capped to the cap placement position of the cap delivery module 300 for cap placement. After cap placement, the first gas canister is transported to the vacuum module for a first vacuuming to obtain the second gas canister. The rotary feeding module transports the second gas canister to the detection module 500 for detection. After detection, the rotary feeding module transports the second gas canister to the calibration module 600 for position calibration to obtain the third gas canister. Finally, the third gas canister is transported to the vacuum module for a second vacuuming to obtain the target gas canister with the cap completed.

[0029] Specifically, during the capping process, the cap-feeding module 300 first automatically places a group of gas canisters to be capped. Each group consists of a first number of gas canisters to be processed. After the cap is initially placed and fitted at the canister opening, the first gas canister with the initial cap is formed. After the capping operation is completed, the first gas canister is precisely transported to the vacuuming station by the rotary feeding module. The vacuuming module then performs the first vacuuming process on the first gas canister with the initial cap, effectively removing the air inside the gas canister and completing the initial vacuum pretreatment, resulting in the second gas canister after the first vacuuming.

[0030] After the initial vacuuming process, the rotary feeding module continues to move the second gas canister to the inspection station, where the inspection module 500 performs position detection on the second gas canister. It accurately identifies the position of the label on the canister surface and the position of the limiting notch 801 on the gas cap, collecting real-time spatial relative position data and generating precise position detection results. Based on the position detection results from the inspection module 500, the equipment control system precisely drives the calibration module 600 to precisely rotate and fine-tune the gas cap on the second gas canister, gradually correcting the relative position of the limiting notch 801 on the gas cap and the label on the canister until they are precisely matched to the system's preset standard relative position, completing the gas cap alignment calibration and obtaining a qualified third gas canister.

[0031] After the lid alignment and calibration process is completed, the third gas canister is transported to the vacuum station again by the rotary feeding module. The vacuum module performs a second high-precision vacuuming operation on the calibrated third gas canister to further optimize the vacuum environment inside the canister and ensure the sealing performance of the canister, thus obtaining a qualified sealed target gas canister.

[0032] In some optional embodiments, the cap delivery module 300 includes a transmission mechanism 310 and a diversion mechanism; the process of obtaining a first gas canister by placing caps on a group of gas canisters to be capped through the cap delivery module 300 includes: S110, The gas cap is conveyed to the diversion mechanism via the transmission mechanism 310; S120. After the gas cap is diverted by the diversion mechanism and transported to the capping area, a group of gas tanks to be capped are simultaneously capped to obtain the first gas tank.

[0033] Specifically, refer to Figure 5 The gas cap delivery module 300 of this application consists of a transmission mechanism 310 and a diversion mechanism. The transmission mechanism 310 is responsible for completing the continuous automatic delivery of gas caps, and the diversion mechanism evenly distributes the delivered gas caps.

[0034] During the capping process, the conveying mechanism 310 of the cap conveying module 300 continuously and orderly conveys the gas caps, transporting the batch of gas caps one by one and smoothly to the working area of ​​the distribution mechanism. This ensures the gas caps remain stable and evenly spaced during transport, preventing stacking, offsetting, and jamming. Once the gas caps reach the distribution mechanism, it evenly distributes them, dividing the gas caps from a single conveying channel into multiple cap materials matching the number of gas cans to be processed, and accurately conveying each to the capping area of ​​the equipment. After completing the gas cap distribution and station alignment, the distribution mechanism simultaneously performs a unified cap placement operation on the entire group of gas cans to be capped, ensuring that the corresponding gas cap is accurately placed on the opening of each can, completing the synchronous initial cap placement operation for the entire group of gas cans, ultimately resulting in the first gas can with caps completed.

[0035] In some optional embodiments, the diversion mechanism includes a first diversion unit and a second diversion unit. The first diversion unit includes a first slider 320, a first groove, a first flow channel 321, a second flow channel 322, and a first horizontal motor 323. The first horizontal motor 323 drives the first slider 320 to slide within the first groove. The first flow channel 321 communicates with a first end of the first groove, and the second flow channel 322 communicates with a second end of the first groove. The transmission mechanism 310 communicates with the middle region of the first groove, which is located between the first and second ends of the first groove. The second diversion unit includes a second slider 330, a second groove, a third flow channel 332, a fourth flow channel 333, a second horizontal motor 331, a third slider 340, a third groove, and a fifth flow channel 34. 2. A sixth flow channel 343, a third horizontal motor 341, a second horizontal motor 331 for driving the second slider 330 to slide within the second slide groove, a third horizontal motor 341 for driving the third slider 340 to slide within the third slide groove, a third flow channel 332 connected to the first end of the second slide groove, a fourth flow channel 333 connected to the second end of the second slide groove, a first flow channel 321 connected to the middle area of ​​the second slide groove, a fifth flow channel 342 connected to the first end of the third slide groove, a sixth flow channel 343 connected to the second end of the third slide groove, and a second flow channel 322 connected to the middle area of ​​the third slide groove; after the gas cap is diverted and transported to the capping area by the diversion mechanism, a group of gas canisters to be capped are simultaneously capped to obtain the first gas canister, including: S121. Real-time acquisition of the gas cap delivery results on the first flow channel 321, the second flow channel 322, the third flow channel 332, the fourth flow channel 333, the fifth flow channel 342 and the sixth flow channel 343; S122. Based on the gas cap delivery result, control the first horizontal motor 323 to drive the first slider 320, the second horizontal motor 331 to drive the second slider 330, and / or the third horizontal motor 341 to drive the third slider 340, so that there is a gas cap on the first flow channel 321, the second flow channel 322, the third flow channel 332, the fourth flow channel 333, the fifth flow channel 342 and the sixth flow channel 343.

[0036] It should be noted that, referring to Figure 5 and Figure 6 The diversion mechanism of this application consists of a first diversion unit and a second diversion unit, forming a two-stage progressive diversion structure. This structure can progressively distribute the single-row gas caps conveyed by the transmission mechanism 310 into a single cap arrangement with six independent flow channels, meeting the production requirements of synchronous and balanced cap supply and release across multiple workstations. The first diversion unit is equipped with a first slider 320, a first chute, a first flow channel 321, a second flow channel 322, and a first horizontal motor 323. The first horizontal motor 323 serves as the power drive component, driving the first slider 320 to perform horizontal reciprocating sliding displacement within the first chute, thereby switching the conduction path of the first chute. The first flow channel 321 corresponds to the first end position of the first chute, and the second flow channel 322 corresponds to the second end position of the first chute. The discharge end of the transmission mechanism 310 of the equipment is connected to the middle area of ​​the first chute. This middle area is located within the interval between the first end and the second end of the first chute, so that the gas caps conveyed by the transmission mechanism 310 can enter from the middle of the first chute and be guided and distributed into the first flow channel 321 or the second flow channel 322 respectively by the position switching of the first slider 320, thus completing the initial two-way diversion operation.

[0037] The second diversion unit is a secondary subdivision diversion structure, specifically including a second slider 330, a second chute, a third flow channel 332, a fourth flow channel 333, a second horizontal motor 331, a third slider 340, a third chute, a fifth flow channel 342, a sixth flow channel 343, and a third horizontal motor 341. The second horizontal motor 331 drives the second slider 330 to slide horizontally within the second chute, switching the flow path of the second chute. The third horizontal motor 341 drives the third slider 340 to slide horizontally within the third chute, switching the flow path of the third chute. The first end of the second chute connects to the third flow channel 332, and the second end connects to the fourth flow channel 333. The discharge end of the first flow channel 321 of the first diversion unit connects to the middle area of ​​the second chute, allowing the gas cap after the initial diversion to enter the second chute of the second diversion unit. Through the position adjustment of the second slider 330, the gas is further diverted to the third flow channel 332 and the fourth flow channel 333. The first end of the third chute connects to the fifth flow channel 342, and the second end of the third chute connects to the sixth flow channel 343. The discharge end of the second flow channel 322 of the first diversion unit connects to the middle area of ​​the third chute. The gas cap that initially flows into the second flow channel 322 can enter the interior of the third chute and, through the position adjustment of the third slider 340, be diverted again to the fifth flow channel 342 and the sixth flow channel 343. Through the step-by-step cooperation of the first and second diversion units, the effect of uniformly distributing caps from a single-path inlet to six independent flow channels can be achieved.

[0038] Specifically, based on the structural configuration of the aforementioned diversion mechanism, the diversion mechanism performs multi-stage diversion of the gas caps and transports them to the capping area, thereby completing the synchronous capping of the entire group of gas tanks awaiting capping and obtaining the first gas tank. The specific process flow is as follows: The equipment system collects the gas cap conveying status and results of the first flow channel 321, the second flow channel 322, the third flow channel 332, the fourth flow channel 333, the fifth flow channel 342, and the sixth flow channel 343 in real time, and judges in real time whether there is gas cap in place, material shortage, material jamming, misalignment, or other working condition information in each flow channel. Based on the real-time gas cap conveying results of each flow channel, the system performs closed-loop precise control of the start, stop, and sliding displacement of the first horizontal motor 323, the second horizontal motor 331, and the third horizontal motor 341. The first horizontal motor 323 drives the first slider 320 to accurately position and switch the path in the first slide groove, the second horizontal motor 331 drives the second slider 330 to accurately position and switch the path in the second slide groove, and the third horizontal motor 341 drives the third slider 340 to accurately position and switch the path in the third slide groove. By coordinating the position adjustment of the slider with multiple motors, the flow direction of the gas caps is precisely allocated step by step. This ensures that each of the six flow channels (321, 322, 332, 333, 342, and 343) accurately retains and positions a single gas cap, achieving synchronous and precise distribution and positioning of the six gas caps. After all gas caps are in place, the distribution mechanism simultaneously performs a unified cap placement operation on the entire group of gas tanks awaiting cap installation, ensuring that the caps are initially placed on the openings of each group of gas tanks, ultimately resulting in the first gas tank with caps installed.

[0039] In some optional embodiments, the first slider 320, the second slider 330, and the third slider 340 have the same structure, each including a first groove 301 disposed at a first end and a second groove 302 disposed at a second end; the step of controlling the first horizontal motor 323 to drive the first slider 320, the second horizontal motor 331 to drive the second slider 330, and / or the third horizontal motor 341 to drive the third slider 340 according to the gas cap delivery result includes: S1221, when the gas cap delivery result indicates that there is no gas cap on the first flow channel 321, the first horizontal motor 323 is controlled to drive the first slider 320 to slide to the first side in the first groove.

S1223. If the gas cap delivery result indicates that there is no gas cap on the third flow channel 332, control the second horizontal motor 331 to drive the second slider 330 to slide towards the first side in the second slide groove. The first groove 301 of the second slider 330 is connected to the third flow channel 332, and the second groove 302 of the second slider 330 is connected to the first flow channel 321, so that the gas cap in the first groove 301 of the second slider 330 flows to the third flow channel 332, and the first flow channel 321 delivers the gas cap to the second groove 302 of the second slider 330. S1224. If the gas cap delivery result indicates that there is no gas cap on the fourth flow channel 333, control the second horizontal motor 331 to drive the second slider 330 to slide to the second side in the second groove. The second groove 302 of the second slider 330 is connected to the fourth flow channel 333, and the first groove 301 of the second slider 330 is connected to the first flow channel 321, so that the gas cap in the second groove 302 of the second slider 330 flows to the fourth flow channel 333, and the first flow channel 321 delivers the gas cap to the first groove 301 of the second slider 330. S1225. If the gas cap delivery result indicates that there is no gas cap on the fifth flow channel 342, control the third horizontal motor 341 to drive the third slider 340 to slide towards the first side in the third slide groove. The first groove 301 of the third slider 340 is connected to the fifth flow channel 342, and the second groove 302 of the third slider 340 is connected to the second flow channel 322, so that the gas cap in the first groove 301 of the third slider 340 flows to the fifth flow channel 342, and the second flow channel 322 delivers the gas cap to the second groove 302 of the third slider 340. S1226. If the gas cap delivery result indicates that there is no gas cap on the sixth flow channel 343, control the third horizontal motor 341 to drive the third slider 340 to slide to the second side in the third slide groove. The second groove 302 of the third slider 340 is connected to the sixth flow channel 343, and the first groove 301 of the third slider 340 is connected to the second flow channel 322, so that the gas cap in the second groove 302 of the third slider 340 flows to the sixth flow channel 343, and the second flow channel 322 delivers the gas cap to the first groove 301 of the third slider 340.

[0040] It should be noted that, referring to Figure 5 and Figure 6 The first slider 320, second slider 330, and third slider 340 of the diversion mechanism are universal sliding switching components with a unified structure. The structural dimensions and functional structures of the first slider 320, second slider 330, and third slider 340 are consistent. Each slider has a groove structure at both ends, with the first end of the slider designated as the first groove 301 and the second end as the second groove 302. These two grooves can respectively realize the functions of temporary receiving, temporary storage, and guiding flow of the gas cap. By horizontally sliding the slider as a whole within the corresponding groove to switch the groove connection path, the on / off switching of different flow channels and automatic material replenishment and diversion operations can be achieved. Based on the unified groove structure of the sliders, the equipment is equipped with precise adaptive sliding control logic for material shortage conditions in the six material conveying channels. According to the real-time gas cap delivery vacancy status of each flow channel, the corresponding slider is driven to complete position switching and directional feeding.

[0041] Specifically, when the system's gas cap delivery result indicates that the first flow channel 321 is in a void state without gas caps, the equipment controls the first horizontal motor 323 to operate, driving the first slider 320 to slide and displace to the first side inside the first groove. After the slider slides into position, the first groove 301 at the end of the first slider 320 forms a communication structure with the first flow channel 321, while the second groove 302 of the first slider 320 forms a communication structure with the discharge end of the upstream conveying mechanism 310. At this time, the gas caps pre-stored inside the first groove 301 of the first slider 320 can flow smoothly to the first flow channel 321 under the action of gravity and conveying thrust, completing the automatic replenishment operation of the first flow channel 321. At the same time, the upstream conveying mechanism 310 continues to operate, accurately delivering new gas caps to the second groove 302 of the first slider 320, completing the pre-storage preparation of the next diverted material.

[0042] When the system's gas cap delivery result indicates that the second flow channel 322 is empty without a gas cap, the equipment controls the first horizontal motor 323 to reverse, driving the first slider 320 to slide and displace to the second side inside the first groove. After the slider slides into place, the second groove 302 of the first slider 320 is connected to the second flow channel 322, and the first groove 301 of the first slider 320 is connected to the discharge end of the upstream conveying mechanism 310. In this state, the gas caps stored inside the second groove 302 of the first slider 320 can be smoothly guided into the second flow channel 322, completing the replenishment operation of the second flow channel 322. At the same time, the conveying mechanism 310 continuously delivers gas caps and accurately delivers them into the first groove 301 of the first slider 320, realizing real-time material storage.

[0043] When the system detects that the third flow channel 332 is without a gas cap and there is a material shortage, the equipment controls the second horizontal motor 331 to start working, driving the second slider 330 to slide towards the first side in the second chute. After the second slider 330 is in place, its first groove 301 is connected to the third flow channel 332, and its second groove 302 is connected to the discharge end of the upstream first flow channel 321. The gas cap temporarily stored in the first groove 301 of the second slider 330 flows into the third flow channel 332, completing the material replenishment of the third flow channel 332. At the same time, the first flow channel 321 continuously conveys gas caps, filling the second groove 302 of the second slider 330, completing the material storage.

[0044] When the system detects that the fourth flow channel 333 is empty and lacks a gas cap, the equipment controls the second horizontal motor 331 to drive the second slider 330 to slide to the second side within the second groove to switch positions. After the position switch is completed, the second groove 302 of the second slider 330 forms a communication channel with the fourth flow channel 333, and the first groove 301 of the second slider 330 remains connected to the upstream first flow channel 321. The gas cap in the second groove 302 of the second slider 330 flows into the fourth flow channel 333 in a directional manner, realizing automatic material replenishment of the fourth flow channel 333. At the same time, the first flow channel 321 continuously supplies material, conveying the gas cap to the first groove 301 of the second slider 330 to complete the material preparation.

[0045] When the system detects an uncapped condition in the fifth flow channel 342, the equipment controls the third horizontal motor 341 to drive the third slider 340 to slide and displace to the first side within the third chute. After the displacement is complete, the first groove 301 of the third slider 340 is connected to the fifth flow channel 342, and the second groove 302 of the third slider 340 is connected to the discharge end of the upstream second flow channel 322. The gas cap temporarily stored in the first groove 301 of the third slider 340 is guided into the fifth flow channel 342, completing the material replenishment operation of the fifth flow channel 342. At the same time, the second flow channel 322 continuously conveys gas caps, transporting them to the second groove 302 of the third slider 340 for temporary storage.

[0046] When the system identifies that the sixth flow channel 343 is empty without a gas cap, the equipment controls the third horizontal motor 341 to drive the third slider 340 to slide to the second side within the third chute to switch positions. After the slider is in place, the second groove 302 of the third slider 340 connects to the sixth flow channel 343, and the first groove 301 of the third slider 340 connects to the upstream second flow channel 322. The gas cap in the second groove 302 of the third slider 340 flows directionally into the sixth flow channel 343, completing the material replenishment operation of the sixth flow channel 343. At the same time, the second flow channel 322 continuously delivers gas caps, filling the first groove 301 of the third slider 340 with gas caps, reserving material for the next round of diversion and replenishment operation. Through the coordinated switching control of the above sliders and motors, the equipment can achieve independent adaptive replenishment of the six flow channels, ultimately ensuring that a single gas cap is accurately retained inside the first flow channel 321, the second flow channel 322, the third flow channel 332, the fourth flow channel 333, the fifth flow channel 342, and the sixth flow channel 343.

[0047] In some alternative embodiments, refer to Figure 7 The third flow channel 332, the fourth flow channel 333, the fifth flow channel 342, and the sixth flow channel 343 are each provided with a first buffer block 350, a second buffer block 351, and a limiting block 352; the process of obtaining the first gas tank after uncapping the gas tank to be capped includes: S130. During the first time period, the gas cylinder flows to the second buffer block 351 after being buffered by the first buffer block 350. S140. During the second time period, the gas cylinder flows to the limiting block 352 after being buffered by the second buffer block 351. S150. During the third time period, the gas cover is blocked by the limiting block 352 so that the gas cover is placed on the gas canister to be covered to obtain the first gas canister.

[0048] It should be noted that the discharge ends of the third flow channel 332, fourth flow channel 333, fifth flow channel 342, and sixth flow channel 343 corresponding to the second diversion unit are all equipped with a first buffer block 350, a second buffer block 351, and a limiting block 352. The three sets of blocks are arranged sequentially along the direction of gas cap descent, forming a multi-stage buffer deceleration and precise limiting and stopping structure. Through the structural design of two-stage buffering and step-by-step energy dissipation combined with end-stage limiting and positioning, problems such as excessive speed, posture deviation, impact misalignment, cap tilting, and hard impact deformation with the can opening can be effectively avoided during the free-falling and capping process of the gas cap. This ensures that each gas cap is placed stably, at low speed, and in a regular posture at the opening of the gas can to be capped, effectively improving the consistency and accuracy of batch capping.

[0049] Specifically, during the first time period of the operation, the gas caps conveyed along each flow channel first contact the first buffer block 350. Through the flexible buffering and damping effect of the first buffer block 350, the high-speed sliding gas caps are initially decelerated and energy dissipated, reducing the falling conveying speed of the gas caps and weakening the sliding inertia of the gas caps. This prevents the gas caps from swaying or deviating due to high-speed straight rush. After the initial buffering and deceleration, the gas caps continue to be conveyed downwards along the flow channel and flow smoothly to the position of the second buffer block 351.

[0050] During the second time period of the operation, the gas cap, after being decelerated by the first-stage buffer, further contacts the second buffer block 351. The second buffer block 351 then performs a second round of fine buffering and pressure stabilization correction on the gas cap. Compared to the initial deceleration function of the first buffer block 350, the second buffer block 351 can further reduce the residual sliding speed of the gas cap and simultaneously fine-tune and correct the left and right offset posture of the gas cap, ensuring that the gas cap always maintains a horizontal and regular falling posture, eliminating undesirable conditions such as swaying and deflection. After the second buffer posture correction, the gas cap continues to descend and is smoothly delivered to the position of the end limit block 352.

[0051] During the third time period of the operation, the descending gas cap is precisely stopped and limited by the limiting block 352. The limiting block 352 blocks the gas cap, restricting its downward displacement and horizontal offset, so that the gas cap is precisely hovered and positioned directly above the pre-set capping position on the corresponding gas tank to be capped. Under the positioning constraint of the limiting block 352, the gas cap is placed smoothly, vertically, and neatly against the opening of the gas tank to be capped, completing the synchronous and precise capping operation of all gas tanks in a single group, and finally obtaining the first gas tank with the capping process completed.

[0052] In some optional embodiments, the vacuuming module includes a first vacuuming unit 400 and a second vacuuming unit 700. The cap feeding module 300, the first vacuuming unit 400, the detection module 500, the calibration module 600, and the second vacuuming unit 700 are arranged sequentially around the rotary feeding module. The second vacuuming unit 700 is used to perform a secondary vacuuming of the third gas canister. The process of obtaining the second gas canister after performing a primary vacuuming of the first gas canister using the vacuuming module includes: S210. During the first time period, control the first vacuum pumping unit 400 to reset to the initial position; S220. During the second time period, control the first vacuum pumping unit 400 to move from the initial position to the preset vacuum pumping position; S230. During the third time period, the first vacuum unit 400 is controlled to perform a vacuuming operation on the first gas tank at the preset vacuuming position to obtain a second gas tank. The second gas tank has a first vacuum degree. The first negative pressure generated by the first vacuum degree in the second gas tank is greater than or equal to the adsorption force that adsorbs the gas cap onto the tank opening, and is less than or equal to the negative pressure corresponding to the maximum rotational force of the calibration module 600.

[0053] It should be noted that the vacuuming module of the gas canister capping equipment of this application is divided into a first vacuuming unit 400 and a second vacuuming unit 700, which are functionally independent but interconnected in process. The equipment adopts a surrounding workstation layout structure, with the cap conveying module 300, the first vacuuming unit 400, the detection module 500, the calibration module 600, and the second vacuuming unit 700 arranged sequentially around the rotary feeding module. Relying on the rotary indexing conveying function of the rotary feeding module, the gas canisters are driven to sequentially complete the closed-loop process of cap placement, primary vacuuming, position detection, cap calibration, and secondary vacuuming. Among them, the first vacuuming unit 400 is dedicated to completing the initial vacuuming operation of the gas canister after cap placement, and the second vacuuming unit 700 is dedicated to completing the secondary high-precision vacuuming operation of the gas canister after cap calibration and positioning. The two-stage vacuuming units have clear division of labor and operate in a gradient manner, which is adapted to the automated processing rhythm of the entire set of equipment.

[0054] Specifically, during the first time period of operation, the equipment system performs a pre-reset procedure for the first vacuum unit 400, precisely controlling the overall movement of the first vacuum unit 400 so that the vacuuming end of the first vacuum unit 400 returns to the preset initial position of the equipment.

[0055] During the second time period of operation, after the gas cylinder is precisely positioned to the vacuuming station by the rotating feeding module and its posture is stable, the system drives the first vacuuming unit 400 to move as a whole, so that the first vacuuming unit 400 moves smoothly and accurately from the initial standby position to the standard vacuuming position preset by the equipment, and completes the precise alignment and fitting of the vacuuming structure with the gas cylinder opening and cover position to form a sealed vacuuming operation cavity.

[0056] During the third time period of the operation, the first vacuum unit 400 is stably maintained at the preset vacuum position and continues to operate. It performs a quantitative and constant pressure vacuuming process on the first gas tank after the cover is placed, continuously extracting the air inside the gas tank, so that the gas pressure inside the tank continues to decrease and forms a stable negative pressure, and finally forms a stable first vacuum inside the gas tank, completing one vacuuming operation and obtaining the second gas tank.

[0057] The first vacuum level corresponds to a first negative pressure inside the can that is greater than or equal to the minimum adsorption force required to stably adhere the gas cap to the gas can opening, while being less than or equal to the critical negative pressure corresponding to the maximum rotational force of the subsequent calibration module 600. This precise limitation of the vacuum parameter achieves two technical effects: firstly, relying on the adsorption effect of the negative pressure inside the can, the initially placed gas cap adheres tightly to the can opening, eliminating problems such as looseness, offset, warping, and misalignment of the cap after placement, preventing the cap from falling off or shifting its posture, and ensuring the recognition accuracy of subsequent visual inspection; secondly, controlling the upper limit of the negative pressure prevents excessive negative pressure inside the can from causing the gas cap to adhere too tightly to the can opening and excessive friction, preventing torque overload, rotational jamming, cap wear, or even inability to rotate when the subsequent calibration module 600 drives the gas cap for alignment. This effectively adapts to the operational requirements of the subsequent precise cap calibration process, ensuring smooth connection of the entire process and stable operational accuracy.

[0058] In some alternative embodiments, refer to Figure 8 and Figure 9The first vacuum unit 400 includes a second number of vacuum devices, the second number being equal to the first number. Each vacuum device includes a vacuum pump and a vacuum communication mechanism. The vacuum communication mechanism includes a vertical motor 410 and a connecting sleeve 420. The connecting sleeve 420 is provided with an elastic connector 422 and a fixing ring 421 fixedly connected to the elastic connector 422. A limiting groove 423 is provided at the first end of the connecting sleeve 420. A communicating hole 424 is provided within the limiting groove 423, communicating with the vacuum pump. 423 is located inside the fixing ring 421. The gas cover includes a cover edge 800 and a cover core groove 810 disposed inside the cover edge 800. The cover core groove 810 is integrally formed with the cover edge 800. A gas nozzle 820 is disposed inside the cover core groove 810. A gas outlet pipe 830 communicating with the gas nozzle 820 is disposed below the cover core groove 810. The gas outlet pipe 830 is bent and disposed opposite to the limiting notch 801 on the cover edge 800. The process of obtaining a second gas tank by performing a vacuuming operation on the first gas tank using the vacuuming module includes: S240. During the first time period, control the vacuum pumping device to reset to the initial position; S250. During the second time period, control the vacuuming device to move from the initial position to directly above the first gas cylinder; adjust the position of the vacuuming device so that the limiting groove 423 is aligned with the cover groove 810 and the fixing ring 421 is aligned with the cover edge 800; control the vacuuming device to approach the first gas cylinder so that after the fixing ring 421 presses against the cover edge 800, the limiting groove 423 is embedded in the cover groove 810 and limits the gas nozzle 820, and the gas nozzle 820 is connected to the communicating hole 424; S260. During the third time period, the extraction time is determined according to the first vacuum degree and the extraction power of the vacuum pump. The vacuum pump is controlled to sequentially evacuate the first gas tank through the connecting hole 424, the gas nozzle 820 and the gas outlet pipe 830 during the extraction time to obtain the second gas tank.

[0059] It should be noted that both the first vacuum unit 400 and the second vacuum unit 700 of the vacuum module are equipped with a second number of vacuum devices. This second number is exactly equal to the first number of gas canisters to be processed, enabling one-to-one synchronous vacuuming of a single group of gas canisters. This ensures that the vacuuming parameters and operating rhythm of the entire group of canisters are consistent, effectively improving the uniformity and efficiency of batch processing. Each vacuum device consists of a vacuum pump and a vacuum communication mechanism. The vacuum communication mechanism, as a sealing and conductive structure for connecting the gas canister cap, includes a vertical motor 410 and a connecting sleeve 420. The connecting sleeve 420 is externally fitted with an elastic connector 422 and a fixing ring 421 fixedly connected to the elastic connector 422. The elastic connector 422 enables flexible pressing and adaptive buffering compensation of the fixing ring 421, effectively adapting to cap assembly errors and ensuring a sealing fit. The first end of the connecting sleeve 420 is provided with a limiting groove 423, and a connecting hole 424 is provided through the limiting groove 423. The connecting hole 424 is connected to the vacuum pump's pumping pipe. The limiting groove 423 is arranged in the inner area of ​​the fixing ring 421, forming a double-layer structure with precise inner limiting and connection and flexible outer sealing and pressing.

[0060] The gas cap with a matching vacuum structure adopts an integrated composite structure, specifically including an outer annular cap rim 800 and a cap core groove 810 located inside the cap rim 800. The cap rim 800 and the cap core groove 810 are integrally formed, resulting in high overall structural strength and stable alignment accuracy. A gas nozzle 820 is fixedly installed at the center of the cap core groove 810. Below the cap core groove 810, a gas outlet pipe 830 is arranged, communicating with the bottom end of the gas nozzle 820. This gas outlet pipe 830 adopts a bent structure design, with the end of the bent gas outlet pipe 830 facing the corresponding limiting notch 801 on the cap rim 800, thus establishing a fixed orientation between the gas outlet passage of the tank and the limiting mark on the cap.

[0061] Specifically, based on the aforementioned one-to-one vacuum device structure and the built-in pipeline structure of the gas cap, the equipment performs a vacuuming operation on the first gas tank obtained after the cap is placed to obtain a second gas tank with a first vacuum degree. The specific operation process is as follows: During the first period of operation, the equipment system uniformly controls all vacuuming devices to perform a reset action, so that all vacuuming devices are raised and returned to their preset initial standby positions.

[0062] During the second time period of the operation, after the rotary feeding module accurately indexes and delivers the entire group of first gas cylinders to the vacuuming station and locks their attitude, the system controls all vacuuming devices to simultaneously and smoothly move down from their initial standby positions, precisely moving them directly above the corresponding first gas cylinders. Subsequently, the system fine-tunes the horizontal position and vertical height of the vacuuming devices in real time to achieve precise structural alignment, ensuring that the limiting groove 423 at the bottom of the connecting sleeve 420 is vertically aligned with the core groove 810 of the gas cap, while simultaneously ensuring that the fixing ring 421 on the outside of the connecting sleeve 420 is horizontally aligned with the edge 800 of the gas cap. After alignment, the vertical motor 410 drives the connecting sleeve 420 downwards to approach the first gas tank, so that the fixing ring 421 is flexibly pressed against the upper end face of the cover edge 800; at the same time, the inner limiting groove 423 is precisely embedded in the inner groove 810 of the cover, forming a circumferential limit and precise wrapping and positioning of the gas nozzle 820 in the inner groove 810, so that the top opening of the gas nozzle 820 is completely aligned with the connecting hole 424 inside the connecting sleeve 420 and reliably connected, thus constructing a complete and sealed gas extraction passage from the connecting hole 424, the gas nozzle 820, the gas outlet pipe 830 to the inside of the gas tank, avoiding problems such as gas leakage, pressure loss, and gas intake during the gas extraction process.

[0063] During the third time period of the operation, the equipment system dynamically calculates based on the preset first vacuum target value and the rated extraction power of the vacuum pump to accurately match and determine the standard extraction time for this vacuuming operation, ensuring that the vacuum level inside the tank is accurately achieved without overshoot. The system controls the vacuum pump to operate stably within the calculated extraction time, continuously extracting air from inside the gas tank through a sealed extraction passage sequentially via the connecting hole 424, the gas nozzle 820, and the outlet pipe 830, causing the gas pressure inside the tank to continuously and steadily decrease, gradually reaching and stabilizing at the preset first vacuum standard, ultimately completing one vacuuming operation for the entire first gas tank, resulting in a second gas tank with a stable negative pressure state, a firmly attached lid, and meeting the requirements of subsequent calibration rotation conditions. The negative pressure inside the tank corresponding to this first vacuum level can reliably hold and fix the gas lid, preventing the lid from loosening or shifting, and can also match the maximum rotation torque of the calibration module 600, ensuring smooth and uninterrupted subsequent lid angle calibration operations.

[0064] In some alternative embodiments, refer to Figure 10 and Figure 11The calibration module 600 includes a third number of calibration devices, each including a calibration motor 610 and a calibration sleeve 620. The first end of the calibration sleeve 620 is connected to the calibration motor 610, and the second end of the calibration sleeve 620 is provided with a calibration groove 621 that engages with the cap groove 810, and a calibration block 622 that engages with the limiting notch 801. The step of controlling the calibration module 600 to rotate the gas cap on the second gas canister according to the position detection result, so that the label and the limiting notch 801 on the gas cap rotate to a preset relative position to obtain the third gas canister, includes: S410. Determine the target rotation angle of the calibration motor 610 based on the first position corresponding to the limiting notch 801 as characterized by the position detection result and the second position corresponding to the placement label. S420, Control the calibration device to approach the second gas cylinder so that the calibration block 622 is embedded in the limiting notch 801 and the calibration groove 621 is embedded in the cover groove 810; S430, Control the calibration motor 610 to rotate the target rotation angle so that the limiting notch 801 and the placement label are in the same vertical plane to obtain the third gas canister.

[0065] It should be noted that the calibration module 600 is equipped with a third number of calibration devices, which matches the first number of gas canisters to be processed in a single group and the second number of vacuum devices. This enables one-to-one precise alignment and calibration of a single canister with a single calibration device, ensuring that the entire group of gas canisters completes the lid alignment process synchronously. Each calibration device consists of a calibration motor 610 and a calibration sleeve 620. The first end of the calibration sleeve 620 is fixedly connected to the power output end of the calibration motor 610 and can synchronously complete precise rotation with the calibration motor 610. The second end of the calibration sleeve 620 integrates a double alignment and fitting structure, namely a calibration groove 621 and a calibration block 622. The calibration groove 621 can achieve precise fitting and matching with the core groove 810 of the gas cap, and the calibration block 622 can achieve gap adaptation and fitting with the limiting notch 801 at the edge 800 of the gas cap. The double fitting structure can completely lock the relative position of the gas cap, avoiding problems such as cap slippage, displacement, and uneven force during rotation calibration, thus ensuring the accuracy of angle calibration.

[0066] Specifically, based on the structure of the above-mentioned calibration module 600, the equipment drives the calibration module 600 to complete the angle calibration of the gas cover of the second gas tank according to the position detection result output by the detection module 500, adjusts the limiting notch 801 and the label on the tank to the preset relative position, and finally obtains the calibrated third gas tank. The specific operation process is as follows.

[0067] The equipment system extracts the position data from the position detection results, determines the first spatial position corresponding to the upper limit notch 801 of the gas cover, and the second spatial position corresponding to the label placed on the gas tank body. By calculating the angle deviation value of the two positions, the target rotation angle required for the calibration motor 610 to rotate is accurately calculated. This angle is the correction angle for the gas cover to complete the precise alignment.

[0068] After determining the target rotation angle, the system controls each group of calibration devices to move down and approach the corresponding second gas tank, so that the end structure of the calibration sleeve 620 is precisely fitted and assembled with the gas cap. Specifically, the calibration block 622 is precisely embedded inside the limiting notch 801 of the gas cap, while the calibration groove 621 is fitted to the outside of the cap core groove 810 of the gas cap. Through the two fitting structures, a stable assembly state of circumferential limiting and axial fitting is formed, realizing the rigid linkage between the calibration sleeve 620 and the gas cap, and ensuring that the rotational torque of the calibration motor 610 can be completely and accurately transmitted to the gas cap.

[0069] After the fitting and assembly are completed, the system precisely controls the calibration motor 610 to rotate at a fixed angle and speed according to the preset target rotation angle. The calibration sleeve 620 drives the gas cover to rotate synchronously, continuously correcting the relative spatial position of the limit notch 801 and the label on the can until the limit notch 801 and the label are completely on the same vertical plane, achieving the standard relative position relationship preset by the system. This completes the precise alignment and calibration of the gas cover, resulting in a third gas can with qualified alignment accuracy and regular posture.

[0070] In some alternative embodiments, refer to Figure 12 and Figure 13 The rotary feeding module includes a rotary conveyor motor 130, a first rotary fixed disk 110, and a second rotary fixed base 120. The rotary conveyor motor 130 is disposed within the base 100 and is rotatably connected to the first rotary fixed disk 110. The second rotary fixed base 120 is fixedly disposed above the first rotary fixed base. The first rotary fixed disk 110 is provided with a first limiting arc groove 111, and the second rotary fixed disk is provided with a second limiting arc groove 121. The gas cylinder is placed on the first rotary fixed disk 110 and fed through the first limiting arc groove 111 and the second limiting arc groove 121. The inner side of the gas cylinder is limited by the positioning groove 121, and the outer side of the gas cylinder is limited by the limiting ring 150 set on the outer side of the first rotating fixed plate 110 and the second rotating fixed base plate 120. A vacuum suction cup 142 is provided between the first rotating fixed plate 110 and the second rotating fixed base plate 120. The vacuum suction cup 142 is used to suction the inner side of the gas cylinder. A vacuum generator 141 and a vacuum controller 140 are provided on the second rotating fixed base plate 120. The vacuum controller 140 is used to control the vacuum generator 141. One vacuum generator 141 is connected to a set of vacuum suction cups 142.

[0071] Specifically, the rotary feeding module consists of a rotary conveyor motor 130, a first rotary fixed disk 110, and a second rotary fixed base 120. The rotary conveyor motor 130 is built into the base 100, and its output end is connected to the first rotary fixed disk 110 to provide indexing rotation power for the entire rotary conveying mechanism. The second rotary fixed base 120 is fixedly mounted above the first rotary fixed disk 110, and both rotate synchronously with the rotary conveyor motor 130.

[0072] The first rotating fixed plate 110 has a first limiting arc groove 111, and the second rotating fixed base plate 120 has a corresponding second limiting arc groove 121. The gas tank is placed on the first rotating fixed plate 110. The first limiting arc groove 111 and the second limiting arc groove 121 together form a circumferential limiting constraint on the inner side of the gas tank. At the same time, a limiting ring 150 is arranged on the outer side of the first rotating fixed plate 110 and the second rotating fixed base plate 120. The limiting ring 150 limits and blocks the outer side of the gas tank. The inner arc groove and the outer limiting ring 150 cooperate with each other to initially achieve radial position constraint of the gas tank and prevent the tank from sliding laterally during the work station switching process.

[0073] A vacuum suction cup 142 is installed between the first rotating fixed plate 110 and the second rotating fixed base 120. The vacuum suction cup 142 can adsorb and fix the gas canister from the inside. The second rotating fixed base 120 is equipped with a vacuum generator 141 and a vacuum controller 140. The vacuum controller 140 realizes the logical control of the start and stop of the vacuum generator 141 and the negative pressure. Each vacuum generator 141 is connected to a set of vacuum suction cups 142 to form an independent and controllable adsorption gas path.

[0074] During equipment operation and as the rotating feeding module drives the gas canisters to move between various functional modules, the vacuum controller 140 activates the vacuum generator 141, causing the vacuum suction cup 142 to generate negative pressure and firmly adhere to the inside of the gas canister. This, together with the inner limiting arc groove and the outer limiting ring 150, forms a multi-positioning constraint system. This combination of mechanical limiting and vacuum adsorption ensures that the gas canister remains stable in position and without deviation throughout the entire process of rotational indexing, station start-up and shutdown, vacuum docking, and cap rotation calibration. This guarantees that the cap conveying module 300, vacuum module, detection module 500, and calibration module 600 can maintain precise alignment with the gas canister, providing a stable and reliable foundation for the entire automated capping process. Specifically, when the feeding module 200 transports the gas canister to be capped to the rotary feeding module, the corresponding vacuum generator 141 is not activated to prevent positional deviation when the gas canister to be capped is transported to the rotary feeding module. When the gas canister to be capped is transported to the cap conveying module 300, the corresponding vacuum generator 141 is activated so that the vacuum suction cup 142 fixes the gas canister to be capped.

[0075] The beneficial effects of this invention include: A first gas canister is obtained by placing a cap on a group of gas canisters to be capped using the cap delivery module 300; the group of gas canisters includes a first number of gas canisters to be capped; a second gas canister is obtained by performing a vacuuming operation on the first gas canister using the vacuuming module; a position detection result is obtained by detecting the position of the placement label and gas cap on the second gas canister using the detection module 500; a third gas canister is obtained by controlling the calibration module 600 to rotate the gas cap on the second gas canister according to the position detection result, so that the placement label and the limiting notch 801 on the gas cap rotate to a preset relative position; and a target gas canister is obtained by performing a second vacuuming operation on the third gas canister using the vacuuming module. In this embodiment, a first vacuuming operation on the gas canister after capping prevents the gas cap from moving freely on the canister opening. Position detection and gas cap position calibration improve the accuracy of the gas cap placement. After the gas cap placement position calibration is completed, a second vacuuming operation using the vacuuming module yields the target gas canister, resulting in high-quality capping of the gas canister.
