[0018] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1 , Figure 2 , Figure 7 and Figure 10 As shown, the present invention proposes a brazing device for liquid-cooled valves and connectors, comprising a housing 1, a sealing door 2 mounted on one side of the housing 1 via a rotating shaft, the sealing door 2 for sealing the housing 1, a first motor 3 fixedly connected to the bottom of the inner wall of the housing 1, a turntable 4 fixedly connected to the output end of the first motor 3, the turntable 4 for driving the valve 5 and other structures to rotate, a mounting base 7 rotatably connected to the top of the turntable 4, the valve 5 mounted on the top of the mounting base 7, the mounting base 7 for fixing the position of the valve 5, and the rotation of the mounting base 7 for driving the valve 5 to rotate, a connector 6 provided on the top of the valve 5, a heater 33 and brazing filler metal 37 installed inside the housing 1, the heater 33 for heating the valve 5 and connector 6. It also includes a drive assembly, a fixing assembly, a cleaning assembly and a welding assembly.

[0020] In this process, such as Figure 2 , Figure 3 , Figure 6 ,Figure 7 and Figure 8 As shown, the drive assembly of the brazing equipment is used to drive the turntable 4, mounting base 7, valve 5, and connector 6. The drive assembly includes a first gear 8, which is fixed to the bottom of the mounting base 7 and located at the bottom of the turntable 4. A bracket 9 is fixed to the inner wall of the housing 1, and a rotating ring 10 is slidably connected to the inner wall of the bracket 9. A toothed ring 11 is fixed to the top of the rotating ring 10. The bracket 9 is used to support the bottom of the rotating ring 10 and the toothed ring 11 and to limit the rotation of the toothed ring 11. Both sides of the toothed ring 11 are provided with transmission teeth, enabling the toothed ring 11 to simultaneously mesh with the first gear 8 and the second gear 13. The inner wall of the toothed ring 11 meshes with one side of the first gear 8. A second motor 12 is fixed to the inner wall of the housing 1. A second gear 13 is fixedly connected to the output end of the motor 12. The second gear 13 meshes with the outer wall of the gear ring 11. When the first motor 3 drives the turntable 4 to rotate, it will drive the four sets of mounting seats 7, connectors 6, valves 5 and the first gear 8 to rotate together with the turntable 4. The first gear 8 meshes with the inner wall of the gear ring 11 on one side. At this time, the gear ring 11 is in a fixed state. Therefore, when the first gear 8 revolves with the turntable 4, it will rotate on the inner wall of the gear ring 11 with which it meshes. Through the cooperation between the gear ring 11 and the first gear 8, the first gear 8 will rotate on its own axis during the revolution. When the first gear 8 rotates on its own axis, it will drive the mounting seats 7, valves 5 and connectors 6 to rotate together. Thus, when the valves 5 and connectors 6 come into contact with the cleaning components, the rotation of the valves 5 and connectors 6 can be used to improve the cleaning efficiency.

[0021] In this embodiment, as Figure 4 and Figure 9As shown, the fixing assembly of the brazing equipment is used to fix the position of valve 5 on the mounting base 7. The fixing assembly includes a first hydraulic rod 14, which is fixed to the inner wall of the mounting base 7. A push plate 15 is fixed to the output end of the first hydraulic rod 14. The first hydraulic rod 14 is used to drive the push plate 15 to move up or down. A groove 26 is formed on the outer wall of the push plate 15. A slide rod 16 is slidably connected to the inner wall of the groove 26. A clamping block 17 is fixed to one end of the slide rod 16. The clamping block 17 is used to fix valve 5. A round rod 18 is fixed to the center of the clamping block 17. The round rod 18 is rotatably connected to the top of the mounting base 7. The round rod 18 is used to move the clamping block 17. There are three sets of clamping blocks 17, round rods 18, and slide rods 16, which are circumferentially distributed on the top of the mounting base 7. When valve 5 is placed on the top of the mounting base 7, the first hydraulic rod 14 can be retracted. 4. When the first hydraulic rod 14 retracts, it can drive the push plate 15 to move downward. When the push plate 15 moves, it will drive the three sets of slide rods 16 in the slide groove 26 to move downward together. When the slide rods 16 move, they will pull one end of the clamping block 17 downward. Since the center of the clamping block 17 is rotatably connected to the mounting base 7 through the round rod 18, when one end of the clamping block 17 moves downward, the other end of the clamping block 17 will flip upward. The tops of the three sets of clamping blocks 17 flip upward at the same time, which can clamp and fix the circular valve 5 at the center. The top of the clamping block 17 is fixed with a protective pad 19. The protective pad 19 is L-shaped and made of rubber. By setting the rubber protective pad 19 at the top of the clamping block 17, the outer wall of the valve 5 can be protected by the protective pad 19 when the three sets of clamping blocks 17 clamp the valve 5, preventing the surface of the valve 5 from being damaged during clamping.

[0022] Furthermore, such as Figure 2 , Figure 3 and Figure 11As shown, the cleaning assembly of the brazing equipment is used to clean the surfaces of valve 5 and connector 6. The cleaning assembly includes a first mounting frame 20, which is fixed to the inner wall of the housing 1. A top frame 21 is fixed to the top of the first mounting frame 20. Two sets of the first mounting frames 20 are provided and symmetrically distributed at the bottom of the top frame 21. A first spring 24 is fixed to the inner wall of the first mounting frame 20. A cleaning plate 22 is fixed to one end of the first spring 24. The first spring 24 is used to push the cleaning plate 22 to one side to reset. A cleaning pad is fixed to one side of the cleaning plate 22. The cleaning pad is used to clean impurities from the surface of valve 5. A connecting block 23 is fixed to the top of the cleaning plate 22. The connecting block 23 is slidably disposed on the inner wall of the top frame 21. The connecting block 23 is used to simultaneously drive the two sets of cleaning plates 22 to move. Two sets of cleaning plates 22 are provided and symmetrically distributed within the two sets of first mounting frames 20. The two sets of cleaning plates 22 are connected by connecting blocks 23. When the valve 5 moves to the inner wall of the first mounting frame 20, since the valve 5 is simultaneously rotating, when the valve 5 contacts the cleaning pad on one side of the cleaning plate 22, the cleaning pad will wipe away the impurities on the surface of the valve 5. When the valve 5 moves to the center of the two sets of cleaning pads, the operation of the first motor 3 can be stopped and the second motor 12 can be started. The second motor 12 can drive the second gear 13 to rotate. Since the second gear 13 meshes with the outer surface of the gear ring 11, the rotation of the second gear 13 will drive the gear ring 11 to rotate. Since the turntable 4 does not rotate when the gear ring 11 rotates, only the mounting base 7, the valve 5 and the connecting piece 6 can rotate in place, which is beneficial for wiping away the impurities on the surface of the valve 5.

[0023] Furthermore, such as Figure 4 and Figure 11As shown, the cleaning assembly also includes a push rod 25, which is fixed to the bottom of a set of cleaning plates 22. A groove 26 is provided at the bottom of the first mounting frame 20, allowing the push rod 25 to slide within it. The push rod 25 is slidably connected to the inner wall of the groove 26. A square frame 27 is mounted on one side of the turntable 4, and a second spring 28 is fixed to the inner wall of the square frame 27. One end of the second spring 28 is fixed to a wedge 29, which pushes the push rod 25 to move. Simultaneously, the inclined surface of the wedge 29 facilitates retraction into the square frame 27. The wedge 29 is located on one side of the push rod 25. After the valve 5 rotates for cleaning, the second motor 12 stops running, keeping the gear ring 11 fixed, and the first motor 3 starts to continue driving the turntable 4 and valve 5 to rotate. When the turntable 4 rotates, it drives the wedge 29 to rotate. When the inclined block 29 contacts the push rod 25, the inclined surface of the inclined block 29 can push the push rod 25 to one side. When the push rod 25 slides in the slide groove 26, it will drive the cleaning plate 22 and the cleaning pad to move together. Therefore, when the valve 5 is removed from the first mounting frame 20, the cleaning pad can be moved to one side to increase the contact area. When the cleaning plate 22 and the cleaning pad move, the cleaning plate 22 will squeeze the first spring 24. When the reset force of the first spring 24 is greater than the pushing force of the second spring 28, the inclined block 29 will be pushed into the inner wall of the square frame 27 through the push rod 25. At this time, there is no longer any obstruction on one side of the push rod 25. The first spring 24 will push the cleaning plate 22, the cleaning pad and the push rod 25 to one side to reset. During the reset process of the cleaning pad, since it is in contact with the surface of the valve 5, the surface of the valve 5 can be wiped again through the reset of the cleaning pad.

[0024] It should be noted that, as Figure 10As shown, the welding assembly of the brazing equipment is used to drive the heater 33 and the brazing filler metal 37 to weld the valve 5 and the connector 6. The welding assembly includes a mounting plate 30, which is fixed to the inner wall of the housing 1. A second hydraulic rod 31 is fixed to the bottom of the mounting plate 30. A base plate 32 is fixed to the output end of the second hydraulic rod 31. A heater 33 is fixed to the bottom of one side of the base plate 32. The heater 33 is used to heat the valve 5, connector 6 and brazing filler metal 37 so that they can be welded together. A base frame 34 is fixed to the bottom of the other side of the base plate 32. A third hydraulic rod 35 is fixed to the inner wall of the base frame 34. A pressure plate 36 is fixedly connected to the output end. The brazing filler metal 37 is disposed at the bottom of the pressure plate 36. A second mounting frame 38 is fixedly connected to one side of the inner wall of the housing 1. A scraper 39 is fixedly connected to the inner wall of the second mounting frame 38. The scraper 39 is used to scrape off excess impurities after welding. The shape of the scraper 39 conforms to the shape of the connection between the valve 5 and the connector 6, which facilitates clamping and fixing the valve 5. Two sets of scrapers 39 are provided and are symmetrically distributed on the inner wall of the second mounting frame 38. When the valve 5 moves to the bottom of the heater 33, the operation of the first motor 3 is stopped. Then, the second hydraulic rod 31 is activated to push the base plate 32 and the heater 33 downward until the base plate 32 is pushed. The brazing filler metal 37 is positioned on one side of valve 5. At this point, heater 33 is activated to heat valve 5. After valve 5 and connector 6 are heated, the third hydraulic rod 35 is retracted to move the pressure plate 36 upwards, releasing the brazing filler metal 37. The inclined brazing filler metal 37 then moves downwards due to gravity until one end of it touches valve 5. Heating the brazing filler metal 37 melts it at the connection between valve 5 and connector 6. The second motor 12 is then activated, driving the second gear 13, gear ring 11, and first gear ring 11 to rotate. Since turntable 4 does not rotate when the first gear ring 11 rotates... Therefore, the mounting base 7, valve 5, and connector 6 can only rotate in place. When the valve 5 rotates, its outer wall can be heated evenly around the circumference, and the brazing filler metal 37 can flow evenly at the connection between the valve 5 and the connector 6 until the valve 5 is welded. After the valve 5 is welded, the first motor 3 will be started to drive the turntable 4 and valve 5 to rotate. When the welded valve 5 moves to the inner wall of the second mounting frame 38, the first motor 3 will stop running again, and the second motor 12 will drive the welded valve 5 to rotate. When the valve 5 rotates, the flux and excess brazing filler metal 37 on the surface of the valve 5 will be scraped off to prevent the excess material from affecting the quality of the valve 5 after welding.

[0025] As one implementation method, such as Figure 2 , Figure 5 and Figure 12As shown, a cylinder 40 is fixed to the center of the inner wall of the housing 1. A filter plate 41 is fixed to the inner wall of the cylinder 40 for filtering impurities. A fan 42 is fixed to the top of the inner wall of the cylinder 40, and the fan 42 is located at the top of the filter plate 41. A side pipe 43 is fixed to one side of the bottom of the cylinder 40, and the side pipe 43 is fixed to one side of a scraper 39. Multiple sets of round holes are opened on one side of the scraper 39 for sucking up the impurities scraped off by the scraper 39. A connecting pipe 44 is fixed to the other side of the bottom of the cylinder 40, and an adsorption frame 45 is fixed to one end of the connecting pipe 44. The adsorption frame 45 is located at the bottom of the first mounting frame 20. When the fan 42 is started, the air below can be drawn upwards. A negative pressure is generated in the side pipe 43, connecting pipe 44, and adsorption frame 45. By setting multiple sets of round holes on one side of the scraper 39, the impurities scraped off by the scraper 39 can be sucked into the side pipe 43. At the same time, the adsorption frame 45 can adsorb and collect the impurities that have fallen off the cleaning plate 22. The adsorbed impurities are sent to the filter plate 41 and filtered by the filter plate 41. A cover plate 46 is fixed to the top of the housing 1. The cover plate 46 is set at the top of the cylinder 40. By setting the cover plate 46 at the top of the housing 1, dust above can be prevented from falling into the cylinder 40. Multiple sets of air vents are opened on the outer wall of the cover plate 46. Multiple sets of dust baffles are installed inside the air vents. By setting multiple sets of dust baffles at the air inlet, dust can be prevented from entering the cylinder 40 from the side.

[0026] In this embodiment, to address the issue that liquid cooling valves and connectors are easily affected by impurities and oxides, when welding is required for the liquid cooling valve, connector 6 can be inserted into the inner wall of valve 5, and valve 5 can be placed at the top of mounting base 7. By retracting the first hydraulic rod 14, push plate 15 can be moved downwards. When push plate 15 moves, it will cause the three sets of slide rods 16 in slide groove 26 to move downwards together. When slide rod 16 moves, it will pull one end of clamping block 17 downwards. Since the center of clamping block 17 is rotatably connected to mounting base 7 through round rod 18, when one end of clamping block 17 moves downwards, the other end of clamping block 17 will flip upwards. The tops of the three sets of clamping blocks 17 flip upwards at the same time, which can clamp and fix the circular valve 5 at the center. The protective pad 19 can protect the outer wall of valve 5 and prevent the surface of valve 5 from being damaged during clamping. Then, by starting the first motor 3, the turntable 4, mounting base 7, valve 5, and connecting piece 6 are driven to rotate. When the first motor 3 drives the turntable 4 to rotate, it drives the four sets of mounting bases 7, connecting pieces 6, valves 5, and the first gear 8 to rotate together with the turntable 4. The first gear 8 meshes with the inner wall of the gear ring 11 on one side. At this moment, the gear ring 11 is in a fixed state. Therefore, when the first gear 8 revolves with the turntable 4, it rotates on the inner wall of the gear ring 11 with which it meshes. Through the cooperation between the gear ring 11 and the first gear 8, the first gear 8 rotates on its own axis during its revolution. And when the first gear 8 rotates on its own axis... The mounting base 7, valve 5, and connector 6 rotate together. When valve 5 moves to the inner wall of the first mounting frame 20, since valve 5 is also rotating, when valve 5 contacts the cleaning pad on one side of the cleaning plate 22, the cleaning pad will wipe away impurities on the surface of valve 5. When valve 5 moves to the center of the two sets of cleaning pads, the operation of the first motor 3 can be stopped and the second motor 12 can be started. The second motor 12 can drive the second gear 13 to rotate. Since the second gear 13 meshes with the outer surface of the gear ring 11, the rotation of the second gear 13 will drive the gear ring 11 to rotate. During rotation, the turntable 4 does not rotate, so only the mounting base 7, valve 5, and connector 6 can rotate in place. This helps to remove impurities from the surface of valve 5. After valve 5 has been cleaned by rotation, the second motor 12 will stop running, keeping the gear ring 11 in a fixed state, and the first motor 3 will start to continue driving the turntable 4 and valve 5 to rotate. When the turntable 4 rotates, it will drive the inclined block 29 to rotate. When the inclined block 29 contacts the push rod 25, the inclined surface of the inclined block 29 can push the push rod 25 to one side. When the push rod 25 slides in the slide groove 26, it will drive the cleaning plate 22 and the cleaning pad to move together. Therefore, when valve 5 is cleaned by rotation, the second motor 12 will stop running, keeping the gear ring 11 in a fixed state, and the first motor 3 will start running to continue driving the turntable 4 and valve 5 to rotate. When the cleaning pad is removed from the first mounting frame 20, it moves to one side to increase the contact area. When the cleaning plate 22 and the cleaning pad move, the cleaning plate 22 will squeeze the first spring 24. When the restoring force of the first spring 24 is greater than the pushing force of the second spring 28, the inclined block 29 will be pushed into the inner wall of the square frame 27 through the push rod 25. At this time, there is no longer any obstruction on one side of the push rod 25. The first spring 24 will push the cleaning plate 22, the cleaning pad and the push rod 25 to one side to reset. During the reset process of the cleaning pad, since it is in contact with the surface of the valve 5, the surface of the valve 5 can be wiped again through the reset of the cleaning pad. When valve 5 moves to the bottom of heater 33, the first motor 3 stops running, and the second hydraulic rod 31 is activated. The second hydraulic rod 31 pushes the base plate 32 and heater 33 downwards until the base plate 32 is pushed to one side of valve 5. Simultaneously, brazing filler metal 37 is positioned on one side of valve 5. At this point, heater 33 is activated to heat valve 5. After valve 5 and connector 6 are heated, the third hydraulic rod 35 retracts. As the third hydraulic rod 35 retracts, it moves the pressure plate 36 upwards, releasing the brazing filler metal 37. The inclined brazing filler metal 37 then releases its weight due to gravity. Move downwards until one end of the brazing filler metal 37 touches the valve 5. The brazing filler metal 37 can be melted by heating at the connection between the valve 5 and the connector 6. At this time, start the second motor 12. The second motor 12 can drive the second gear 13, the gear ring 11 and the first gear ring 11 to rotate. Since the turntable 4 does not rotate when the first gear ring 11 rotates, only the mounting base 7, the valve 5 and the connector 6 can rotate in place. When the valve 5 rotates, its outer wall can be automatically heated evenly around the circumference, and the brazing filler metal 37 can flow evenly at the connection between the valve 5 and the connector 6 until the valve 5 is welded. When the welded valve 5 moves to the inner wall of the second mounting frame 38, the first motor 3 will stop running again, and the second motor 12 will drive the welded valve 5 to rotate. When the valve 5 rotates, the flux and excess brazing filler metal 37 remaining on the surface of the valve 5 will be scraped off to prevent the excess material from affecting the quality of the welded valve 5. Then the blower 42 will be started to draw the air from below to the top, which will create a negative pressure in the side pipe 43, connecting pipe 44 and adsorption frame 45. By setting multiple sets of round holes on one side of the scraper 39, the impurities scraped off by the scraper 39 can be sucked into the side pipe 43. At the same time, the adsorption frame 45 can adsorb and collect the impurities that have fallen off the cleaning plate 22. The adsorbed impurities will be sent to the filter plate 41 and filtered by the filter plate 41.
