Description

Technical Field

[0001] This application relates to the field of alkali metal filling technology, specifically to a high-quality and precise filling device for alkali metal working fluid. Background Technology

[0002] Alkali metals refer to six metallic elements belonging to the same group in the periodic table: lithium, sodium, potassium, rubidium, cesium, and francium. Alkali metals share many similar properties; they are all silvery-white metals with low density, low melting and boiling points, and high reactivity under standard conditions. High-temperature heat pipes use liquid alkali metals as the working fluid, which are highly reactive metals. They fully utilize the principles of heat conduction and the rapid heat transfer properties of phase-change media to quickly transfer heat from the heat source to the outside of the heat-generating object. Their thermal conductivity exceeds that of any known metal.

[0003] Because alkali metals are easily oxidized, existing alkali metal filling technologies typically involve evacuating the filling tank and the system to be filled, filling them with inert gas, and then heating a solid working fluid inside the filling tank to fill the liquid alkali metal working fluid into the workpiece. In these existing technologies, the quality of the final alkali metal working fluid filled into the workpiece is controlled by the amount of solid working fluid placed in the filling tank. Only one workpiece can be filled at a time, and the filling tank and the system to be filled need to be evacuated constantly. During this process, the liquid alkali metal working fluid in the pipeline partially solidifies, affecting not only the quality of the filled alkali metal working fluid but also requiring pipeline cleaning. Therefore, existing technologies cannot efficiently and accurately fill alkali metal working fluids. Summary of the Invention

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A high-quality, precise filling device for alkali metal working fluid includes a gas filling chamber, a gas extraction chamber, a constant-temperature sealing chamber, an alkali metal working fluid filling tank, and a conveying mechanism. The alkali metal working fluid filling tank is mounted on the conveying mechanism and can sequentially pass through the gas filling chamber, the gas extraction chamber, and the constant-temperature sealing chamber along the conveying mechanism. The gas filling chamber includes a first horizontal position adjustment structure, a first vertical position adjustment structure, a first robotic arm, and a gas filling mechanism. The gas filling mechanism is mounted on the first vertical position adjustment structure. The initial gas filling in the alkali metal working fluid filling tank... The state is a vacuum state. The gas filling mechanism can fill the alkali metal working medium filling tank with gas and fill the gas pressure in the alkali metal working medium filling tank to X1 Pa, where X1 is a preset value. The gas extraction chamber includes a second horizontal position adjustment structure, a second vertical position adjustment structure and a working medium filling mechanism. The working medium filling mechanism is set on the second vertical position adjustment structure. The working medium filling mechanism includes a material suction nozzle, a suction valve, a material storage tank, a material filling nozzle and a material filling valve. During the filling process in the material storage tank, the gas pressure is maintained at a constant X1 Pa.

[0006] Furthermore, the gas filling mechanism includes a filling nozzle, a filling valve, a first communication module, and a connection interface that can be connected to an inert gas filling source. The first communication module can wirelessly communicate with the pressure sensor on the alkali metal working medium filling tank and control the opening and closing of the filling valve through a signal.

[0007] Furthermore, the first horizontal position adjustment structure is connected to the first robotic arm and can adjust the horizontal position of the first robotic arm. The first vertical position adjustment structure is disposed on the first horizontal position adjustment structure and can change the horizontal position of the first vertical position adjustment structure by moving the first horizontal position adjustment structure.

[0008] Furthermore, the second vertical position adjustment structure is disposed on the second horizontal position adjustment structure and the horizontal position of the second vertical position adjustment structure can be changed by moving the second horizontal position adjustment structure, and the working fluid filling mechanism is disposed on the second vertical position adjustment structure.

[0009] Furthermore, the working fluid filling mechanism also includes a second communication module, which can wirelessly communicate with the pressure sensor on the alkali metal working fluid filling tank and control the opening and closing of the suction valve and the material filling valve through signals.

[0010] Furthermore, the constant temperature packaging chamber includes a pusher plate mechanism and a welding packaging mechanism. The pusher plate mechanism can push the packaging plate to a suitable position, and the welding packaging mechanism can weld and package the openings on the packaging plate.

[0011] Furthermore, the alkali metal working fluid filling tanks are multiple and can be arranged in a conveying frame. The conveying frame includes a snap-fit ​​groove, and the bottom of the alkali metal working fluid filling tank can cooperate with the snap-fit ​​groove to ensure that the alkali metal working fluid filling tank is vertically fixed in the conveying frame.

[0012] Furthermore, the filling equipment also includes a pusher mechanism, which includes a telescopic motor and a sliding plate fixedly mounted on the telescopic rod of the telescopic motor. A conveying frame is provided on the sliding plate, and the sliding plate can be transported to a designated position for the first robotic arm to grasp by the extension and retraction of the telescopic motor.

[0013] Furthermore, the alkali metal working fluid filling tank is equipped with a gas filling port, a gas extraction port, a safety pressure relief valve, a pressure sensor, and a communication module. Both the gas filling port and the gas extraction port are equipped with one-way gas valves, and the pressure sensor and the communication module are electrically connected.

[0014] Furthermore, when the filling equipment is working, protective gas needs to be injected into the gas filling chamber, gas extraction chamber, and constant temperature sealing chamber first. The gas filling chamber, gas extraction chamber, and constant temperature sealing chamber are all in a gas-sealed state when they are working. When the conveyor frame enters or leaves the sealed space of the gas filling chamber, gas extraction chamber, or constant temperature sealing chamber, the gas filling chamber, gas extraction chamber, and constant temperature sealing chamber stop working first. After the gas sensor is turned on to detect the gas composition and concentration in the space and they are qualified, the gas filling chamber, gas extraction chamber, and constant temperature sealing chamber start working.

[0015] Beneficial effects

[0016] (1) This application sets up a filling equipment in the form of an assembly line, so that the alkali metal working medium filling tank can pass through the gas filling chamber, the gas extraction chamber and the constant temperature sealing chamber in sequence for systematic working medium filling. During the entire filling process, there is no need to stop the machine and wait for the previous step to be completed. The high integration improves the work efficiency and avoids the operation of frequently adjusting the connection when filling alkali metal working medium in the prior art, which requires multiple filling steps at the same station and waiting for the previous step to be completed. This improves the time efficiency of alkali metal working medium filling. This application also uses the gas extraction chamber to quantitatively extract the gas in the alkali metal working medium filling tank. The quantitative extraction of the gas in the alkali metal working medium filling tank through the gas extraction chamber ensures the quality of alkali metal working medium filling. It can not only ensure the accuracy of filling but also the efficiency of filling.

[0017] (2) This application designs an alkali metal working medium filling tank, which is equipped with a pressure sensor and a corresponding communication structure to transmit the gas pressure inside the alkali metal working medium filling tank to the outside in real time. The filling process of the gas filling mechanism is controlled by the value of the pressure sensor, ensuring that the gas pressure inside the alkali metal working medium filling tank is the same, which further improves the accuracy of the subsequent filling process. At the same time, the real-time monitoring of the gas pressure inside the alkali metal working medium filling tank can ensure the sealing of the alkali metal working medium filling tank and avoid the possibility of alkali metal being oxidized during the production process.

[0027] The following detailed description of embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0028] like Figure 1-9A high-quality, precise filling device for alkali metal working fluid includes a gas filling chamber 1, a gas extraction chamber 2, a constant-temperature sealing chamber 3, an alkali metal working fluid filling tank 4, and a conveying mechanism 5. The alkali metal working fluid filling tank 4 is mounted on the conveying mechanism 5 and can sequentially pass through the gas filling chamber 1, the gas extraction chamber 2, and the constant-temperature sealing chamber 3 along the conveying mechanism. The gas filling chamber 1 includes a first horizontal position adjustment structure 101, a first vertical position adjustment structure 102, a first robotic arm 103, and a gas filling mechanism 104. The gas filling mechanism 104 is mounted on the first vertical position adjustment structure 102. The initial state inside the alkali metal working fluid filling tank 4 is a vacuum state. The gas filling mechanism 104 can fill the alkali metal working medium filling tank 4 with gas and fill the gas pressure in the alkali metal working medium filling tank 4 to X1 Pa, where X1 is a preset value; the gas extraction chamber 2 includes a second horizontal position adjustment structure 201, a second vertical position adjustment structure 202 and a working medium filling mechanism 204. The working medium filling mechanism 204 is disposed on the second vertical position adjustment structure 202. The working medium filling mechanism 204 includes a material suction nozzle 2041, a suction valve 2042, a material storage tank 2043, a material filling nozzle 2044 and a material filling valve 2045. During the filling process, the gas pressure in the material storage tank 2043 is maintained at a constant X1 Pa.

[0029] This application, based on the traditional alkali metal working fluid filling structure, sets up a production line-type filling equipment, allowing the alkali metal working fluid filling tank 4 to be systematically filled by sequentially passing through the gas filling chamber 1, the gas extraction chamber 2, and the constant temperature sealing chamber 3. The gas extraction chamber 2 quantitatively extracts gas from the alkali metal working fluid filling tank 4, ensuring that the gas pressure in the material storage tank 2043 is the same as the pressure in the alkali metal working fluid filling tank 4 after filling (both are X1 Pa). This quantitative extraction of gas from the alkali metal working fluid filling tank 4 by the gas extraction chamber 2 ensures the quality of the alkali metal working fluid filling, guaranteeing both filling accuracy and efficiency. Furthermore, this application performs different filling steps at each operating station, highly integrating processes to improve work efficiency. It avoids the need for multiple filling steps at the same station in existing technologies, where each step requires waiting for the previous step to complete and frequent adjustments to the connections, thus improving the time efficiency of alkali metal working fluid filling.

[0030] Furthermore, the gas filling mechanism 104 includes a filling nozzle 1041, a filling valve 1042, a first communication module 1044, and a connection interface 1043 that can communicate with an inert gas filling source. The first communication module 1044 can wirelessly communicate with the pressure sensor 404 on the alkali metal working medium filling tank 4 and control the opening and closing of the filling valve 1042 through signals. This application, by setting a pressure sensor 404 and a corresponding communication structure on the alkali metal working medium filling tank 4, can transmit the gas pressure inside the alkali metal working medium filling tank 4 to the outside in real time. The filling process of the gas filling mechanism 104 is controlled by the value of the pressure sensor 404, ensuring that the gas pressure inside the alkali metal working medium filling tank 4 is the same, further improving the accuracy of the subsequent filling process. At the same time, the real-time monitoring of the gas pressure inside the alkali metal working medium filling tank 4 can ensure the sealing of the alkali metal working medium filling tank 4 and avoid the possibility of alkali metal oxidation during the production process.

[0031] Preferably, the first horizontal position adjustment structure 101 is connected to the first robotic arm 103 and can adjust the horizontal position of the first robotic arm 103. The first vertical position adjustment structure 102 is disposed on the first horizontal position adjustment structure 101 and can change the horizontal position of the first vertical position adjustment structure 102 by moving the first horizontal position adjustment structure 101.

[0032] Furthermore, the second vertical position adjustment structure 202 is disposed on the second horizontal position adjustment structure 201 and the horizontal position of the second vertical position adjustment structure 202 can be changed by moving the second horizontal position adjustment structure 201. The working fluid filling mechanism 204 is disposed on the second vertical position adjustment structure 202.

[0033] Preferably, the working fluid filling mechanism 204 further includes a second communication module 2046. The second communication module 2046 can be wirelessly connected to the pressure sensor 404 on the alkali metal working fluid filling tank 4, and control the opening and closing of the suction valve 2042 and the material filling valve 2045 through signals. The filling beyond the rated amount can also be achieved by controlling the adjustment through the change of the pressure sensor 404 value, ensuring that the working fluid filling of the equipment can be quantitatively adjusted, and increasing the filling flexibility of the present invention.

[0034] Furthermore, the constant temperature packaging chamber 3 includes a push plate mechanism 301 and a welding packaging mechanism 302. The push plate mechanism 301 can push the packaging plate 303 to a suitable position, and the welding packaging mechanism 302 can weld and package the opening on the packaging plate 303.

[0035] Furthermore, there are multiple alkali metal working fluid filling tanks 4, which can be arranged in the conveying frame 6. The conveying frame 6 includes a snap-fit ​​groove 601. The bottom of the alkali metal working fluid filling tank 4 can cooperate with the snap-fit ​​groove 601 to ensure that the alkali metal working fluid filling tank 4 is vertically fixed in the conveying frame 6.

[0036] Furthermore, the conveying frame 6 also includes a gripper 602 and a positioning and locking device 603. The gripper 602 is disposed at the upper end of the conveying frame 6 and protrudes outward from the outer wall of the conveying frame 6. The bottom end face of the gripper 602 is provided with a slot, which can cooperate with the end plate 1032 of the first robot arm 103. The gripper 602 enables the first robot arm 103 to grab the conveying frame 6 from the placement rack and place it on the conveying mechanism 5, so that the alkali metal working fluid filling tank 4 can move in multiple positions along the direction of the conveying mechanism 5.

[0037] Furthermore, the conveying mechanism 5 includes a conveying roller 501 and a conveying chain 502. The conveying roller 501 is rotatably mounted on the conveying mechanism 5 and can support the conveying frame 6 to move along the conveying mechanism 5. A fixing plate 503 is fixedly mounted on the conveying chain 502. Multiple sets of fixing plates 503 are correspondingly arranged, each set including two fixing plates 503. Each fixing plate 503 is provided with a fixing clamp 504. The fixing clamps 504 on each set of fixing plates 503 are symmetrically arranged. When the conveying... When frame 6 is placed above a set of fixed plates 503, the fixed clamp 504 abuts against the positioning latching device 603. At this time, the first robot arm 103 releases the conveying frame 6 so that it can fall freely under its own weight. When the fixed clamp 504 is pressed down by the positioning latching device 603 and moves downward, the roller 505 on the fixed clamp 504 can roll along the edge of the positioning latching device 603 and press the positioning latching device 603 under the fixed clamp 504 by the compression spring.

[0038] Furthermore, the filling equipment also includes a pusher mechanism 7, which includes a telescopic motor 701 and a sliding plate 702 fixedly mounted on the telescopic rod of the telescopic motor 701. The sliding plate 702 is provided with a conveyor frame 6. The sliding plate 702 can be transported to a designated position by the extension and retraction of the telescopic motor 701 for the first robotic arm 103 to grasp.

[0039] Preferably, the alkali metal working fluid filling tank 4 is provided with a gas filling port 401, a gas extraction port 402, a safety pressure relief valve 403, a pressure sensor 404, and a communication module. Both the gas filling port 401 and the gas extraction port 402 are provided with gas one-way valves, and the pressure sensor 404 is electrically connected to the communication module.

[0040] Preferably, when the filling equipment is working, protective gas needs to be injected into the gas filling chamber 1, gas extraction chamber 2, and constant temperature sealing chamber 3 first. The gas filling chamber 1, gas extraction chamber 2, and constant temperature sealing chamber 3 are all in a gas-sealed state when working. When the conveyor frame 6 enters or leaves the sealed space of the gas filling chamber 1, gas extraction chamber 2, or constant temperature sealing chamber 3, the gas filling chamber 1, gas extraction chamber 2, and constant temperature sealing chamber 3 stop working first. After the gas sensor is turned on to detect the gas composition and concentration in the space and they are qualified, the gas filling chamber 1, gas extraction chamber 2, and constant temperature sealing chamber 3 start working.

[0041] Traditional alkali metal filling technology can only fill one workpiece at a time, requiring constant vacuuming of the filling tank and the system to be filled. During this process, the liquid alkali metal working fluid in the pipeline partially solidifies, affecting the quality of the filled alkali metal working fluid and necessitating pipeline cleaning. This results in the inefficiency and inaccuracy of filling alkali metal working fluid in existing technologies. This application, by setting up a production line-type filling equipment, allows the alkali metal working fluid filling tank to sequentially pass through a gas filling chamber, a gas extraction chamber, and a constant-temperature sealing chamber for systematic working fluid filling. The entire filling process does not require machine downtime to wait for the previous step to complete. This high integration improves work efficiency and avoids the frequent adjustments to connections required in existing technologies where multiple filling steps are performed at the same station, each waiting for the previous step to complete. This significantly reduces the filling time of alkali metal working fluid. Efficiency; This application also uses a gas extraction chamber to quantitatively extract gas from the alkali metal working medium filling tank. This quantitative extraction ensures the filling quality of the alkali metal working medium, guaranteeing both filling accuracy and efficiency. Furthermore, the design of the alkali metal working medium filling tank incorporates a pressure sensor and corresponding communication structure, enabling real-time signal transmission of gas pressure between the tank and the outside environment. The pressure sensor 404's readings control the filling process of the gas filling mechanism 104, ensuring uniform gas pressure within the tank and further improving the accuracy of subsequent filling processes. Simultaneously, real-time monitoring of the gas pressure within the tank ensures its sealing, preventing the possibility of oxidation of the alkali metal during production.
