Description

Technical Field

[0001] This invention relates to the field of air conditioning pipe connection component assembly technology, specifically to a copper connector for connecting copper tubes of an air conditioner condenser and tooling for manufacturing condenser copper tubes. Background Technology

[0002] A condenser coil is a component used to facilitate condensation, typically in heat exchange processes, to cool and condense medium- to high-temperature gases into liquids. In split air conditioning systems, the main function of the condenser coil is to cool and liquefy the high-temperature, high-pressure gaseous refrigerant discharged from the compressor, thereby releasing heat to prepare for the subsequent evaporation and heat absorption process.

[0003] The existing condenser tube welding lacks tooling and relies mainly on fixing with wire, which is highly arbitrary, difficult to operate, and makes it hard to control the dimensions and welding precision. Summary of the Invention

[0004] The present invention aims to overcome the shortcomings of the prior art.

[0005] A copper connector for connecting copper tubes in an air conditioner condenser and a tooling for manufacturing condenser copper tubes are proposed. The connector includes a drive device, a rotating assembly, an air supply device, copper connectors, and a support assembly. The drive device is located below the rotating assembly, and the air supply device is vertically located at the center of the rotating assembly and connected to the rotating assembly. The rotating assembly is provided with multiple copper connectors, and each copper connector has a corresponding set of support assemblies on its inner side. Each set of support assemblies is connected to the rotating assembly.

[0006] The technical solution of this invention is used to address the shortcomings mentioned in the technical background.

[0007] In a preferred embodiment of the present invention, the driving device includes a base support, a base plate, a motor, a main gear, support wheels, and a limiting ring. The base plate is connected above the base support, the motor is located on one side of the base plate, the main gear is located above the motor, and there are multiple support wheels, all located above the base plate, with the support wheels evenly distributed around the axis of the base plate. The limiting ring is located at the center of the base plate and connected to the rotating assembly. Each support wheel is in contact with the lower surface of the secondary gear of the rotating assembly. Therefore, when the secondary gear rotates around its axis, the support wheel can rotate synchronously with the secondary gear, thereby ensuring that the support wheel can provide support while reducing the friction between the secondary gear and the base plate.

[0008] In a preferred embodiment of the present invention, the rotating assembly includes a secondary gear, a rotating disk, a rotating ring, a support frame, and a synchronizing ring. The secondary gear is located below the rotating disk and meshes with the main gear. The rotating ring is located above the rotating disk and connected to the rotating disk through the support frame. The synchronizing ring is located inside the rotating ring and connected above it. The support assembly is connected to the synchronizing ring. When the rotating ring rotates, it drives the synchronizing ring to rotate synchronously. Since the support assembly is connected to the synchronizing ring, when the synchronizing ring rotates, it drives the support assembly and the condenser tube on the support assembly to rotate synchronously.

[0009] In a preferred embodiment of the present invention, the rotating ring is provided with multiple air outlet pipes, each air outlet pipe is provided with a valve above it, and each valve is provided with a first diverter at its air outlet. The first diverter is preferably connected to the diverter by means of threaded connection or flange connection, so that after the valve is opened, the gas inside the rotating ring can be ejected through the first diverter.

[0010] In a preferred embodiment of the present invention, each of the first distributors is provided with a copper connector, one end of the condenser tube is connected to the inside of the copper connector, and the other end of the condenser tube is connected to the support assembly. The first distributor is connected to the condenser tube on the support assembly, so the nitrogen gas sprayed out through the first distributor can enter the condenser tube and the inside of the copper connector.

[0011] In a preferred embodiment of the present invention, the support assembly includes a support rod, a support block, a clamping block, and a locking block. The support rod is vertically positioned in the middle of the rotating ring and the synchronizing ring. There are multiple support blocks, each located on one side of the support rod. Each support block has a condenser tube. The clamping block and the locking block are respectively located above and below the synchronizing ring, with one end of the clamping block connected to the support rod. After the clamping block is connected to the support rod and the locking block, the synchronizing ring can drive the support rod and the condenser tube on the support rod to rotate synchronously when it rotates.

[0012] In a preferred embodiment of the present invention, the support block has a slot at the position corresponding to the condenser tube, and the support block has two threaded holes at one end of the support rod, with bolts installed in the threaded holes. The slots on the multiple support blocks connected to the support rod are not in the same position, thereby accommodating condenser tubes with different bending angles.

[0013] In a preferred embodiment of the present invention, the support rod is provided with multiple threaded holes, and the specifications of the threaded holes on the support rod correspond to the specifications of the threaded holes on the support block. Therefore, after the end of the bolt passes through the threaded hole on the support rod, the end of the bolt can be turned into the threaded hole opened on the support block, thereby connecting the support block and the support rod together.

[0014] In a preferred embodiment of the present invention, the gas supply device includes a pressure sensor, a fixed housing, an air inlet pipe, a second distributor, a sealing ring, a guide pipe, and a signal valve. The pressure sensor is connected to the rotating ring, the fixed housing is connected to the center of the base support, the air inlet pipe is located below the fixed housing, the second distributor is located at the center of the rotating disk, and its lower end is connected to the fixed housing. The sealing ring is located inside the fixed housing. There are four guide pipes, all located above the rotating disk, and all four guide pipes are connected to a third distributor on the outside of the rotating ring. The signal valve is connected to the air inlet pipe. When the pressure sensor detects that the pressure inside the rotating ring is too high, the signal valve will close, preventing gas from entering the rotating ring through the second distributor. When the pressure sensor detects that the pressure inside the rotating ring is too low, the signal valve will open, allowing gas to enter the rotating ring through the second distributor.

[0015] In a preferred embodiment of the present invention, four third distributors and distributor pipes are provided on the outer side of the rotating ring. The positions of the four third distributors correspond to the positions of the four gas guide pipes. Each end of the third distributor is provided with a distributor pipe, and both distributor pipes are connected to the rotating ring. Therefore, nitrogen gas that enters the interior of the third distributor through the gas guide pipes can enter the interior of the rotating ring.

[0016] The beneficial effects of this invention compared to the prior art are: In this invention, when welding condenser tubes, the lower end of the condenser tube is inserted into the copper connector and connected to the first distributor, while the upper end of the condenser tube is inserted into a pre-set slot in the support block. This restricts the position of the condenser tube, preventing it from moving during welding, and ensuring the worker's welding position remains unchanged. When the drive device moves the condenser tube and copper connector to the welding position, it moves the same position of the condenser tube and copper connector on different support assemblies to the welding position, thus ensuring welding accuracy. At the same time, during welding, the gas supply device continuously supplies nitrogen gas into the condenser tube and copper connector, thereby preventing the condenser tube and copper connector from being blocked or oxidized.

Detailed Implementation

[0018] The following will refer to the appendices in the embodiments of the present invention. Figure 1-22 The technical solutions in the embodiments of the present invention will be described in detail below. Example 1

[0019] like Figure 1 As shown, a copper connector for connecting copper tubes of an air conditioner condenser and a tooling for manufacturing condenser copper tubes include a drive device 1, a rotating assembly 2, an air supply device 3, a copper connector 4, and a support assembly 5. The drive device 1 is located below the rotating assembly 2 and at the center of the rotating assembly 2, and the drive device 1 is connected to the rotating assembly 2.

[0020] like Figure 1 As shown, when needed, the drive device 1 can drive the rotating component 2 to rotate. The air supply device 3 is vertically arranged at the center of the rotating component 2 and is connected to the rotating component 2. When the drive device 1 drives the rotating component 2 to rotate.

[0021] like Figure 1 As shown, the rotating component 2 will drive the gas supply device 3 to rotate synchronously. The rotating component 2 is provided with multiple copper connectors 4, and each copper connector 4 has a corresponding set of bracket components 5 on its inner side. Each set of bracket components 5 is provided with a condenser pipe 41, and the condenser pipe 41 on each set of brackets is connected to its corresponding copper connector 4.

[0022] like Figure 2-4 As shown, the drive device 1 includes a base bracket 11, a base plate 12, a motor 13, a main gear 14, a support wheel 15, and a limiting ring 16. The base bracket 11 is vertically arranged below the rotating component 2, and the base bracket 11 is located at the center of the rotating component 2.

[0023] like Figure 2-4 As shown, the base plate 12 is positioned above the base bracket 11 and connected to the center of the base plate 12. The connection between the base plate 12 and the base bracket 11 is a fixed connection. There are multiple support wheels 15, all positioned above the base plate 12, and the support wheels 15 are evenly distributed around the axis of the base plate 12.

[0024] like Figure 2-4 As shown, each support wheel 15 is rotatably connected to the base plate 12 via a bearing, so the support wheel 15 can rotate around the axis. Each support wheel 15 is in contact with the lower surface of the secondary gear 21 of the rotating assembly 2.

[0025] like Figure 2-4 As shown, when the auxiliary gear 21 rotates around its axis, the support wheel 15 can rotate synchronously with the auxiliary gear 21, thereby ensuring that the support wheel 15 can provide support while reducing the friction between the auxiliary gear 21 and the base plate 12.

[0026] like Figure 2-4 As shown, the number of drive support wheels 15 can be increased or decreased according to usage requirements. For example, when the diameter of the auxiliary gear 21 increases, the diameter of the base plate 12 will also increase. At this time, the number of support wheels 15 on the base plate 12 can be increased to ensure that the distance between adjacent support wheels 15 will not cause the rotating component 2 to overturn.

[0027] like Figure 2-4 As shown, the limiting ring 16 is located at the center of the base plate 12, and the lower end of the limiting ring 16 is fixedly connected to the base plate 12. A through hole is provided at the center of the limiting ring 16 along the axis to ensure that the air supply device 3 can pass through the center of the limiting ring 16.

[0028] like Figure 2-4 As shown, the top end of the drive limiting ring 16 is connected to the secondary gear 21 through a bearing. The outer ring of the bearing is connected to the limiting ring 16, and the inner ring of the bearing is connected to the secondary gear 21, thereby ensuring that the limiting ring 16 will not obstruct the secondary gear 21 when it rotates.

[0029] like Figure 2-4 As shown, the drive motor 13 is vertically arranged on one side of the base plate 12 and is connected to the base plate 12. The main gear 14 is horizontally arranged above the base plate 12 and is connected to the output shaft of the motor 13 by a key.

[0030] like Figure 2-4 As shown, the motor 13 used for driving is preferably a stepper motor 13 or a servo motor 13, so as to ensure that the output shaft of the motor 13 can rotate a specific number of revolutions in a single operation under human control, and then after rotating to the specific number of revolutions, the output shaft of the motor 13 can stop and wait for the next start.

[0031] like Figure 2-4 As shown, when the output shaft of the drive motor 13 rotates, it will drive the main gear 14 to rotate synchronously. The main gear 14 meshes with the secondary gear 21. When the main gear 14 rotates under the drive of the motor 13, it can drive the secondary gear 21 to rotate synchronously. When the secondary gear 21 rotates, it can drive the rotating disk 22 to rotate synchronously, thereby limiting the rotation angle of the rotating disk 22 in one go.

[0032] like Figure 5 As shown, the rotating assembly 2 includes a secondary gear 21, a rotating disk 22, a rotating ring 23, a support frame 24, and a synchronizing ring 25. The secondary gear 21 is arranged laterally below the rotating disk 22, and the axis of the secondary gear 21 coincides with the axis of the rotating disk 22.

[0033] like Figure 5As shown, the upper surface of the auxiliary gear 21 is fixedly connected to the lower surface of the rotating disk 22, and the lower surface of the auxiliary gear 21 is in contact with the support wheel 15. Therefore, when the auxiliary gear 21 rotates, it can drive the rotating disk 22 to rotate synchronously.

[0034] like Figure 5 As shown, the rotating ring 23 is positioned above the rotating disk 22, and the rotating ring 23 and the rotating disk 22 are coaxially arranged. There are four support frames 24, all of which are vertically positioned below the rotating ring 23, and the four support frames 24 are evenly arranged with the axis of the rotating ring 23 as the center.

[0035] like Figure 5 As shown, the upper and lower ends of the support frame 24 are fixedly connected to the rotating ring 23 and the rotating disk 22, respectively. Therefore, when the rotating disk 22 rotates, it can drive the rotating ring 23 to rotate synchronously through the support frame 24. The rotating ring 23 is hollow inside and is preferably made of stainless steel.

[0036] like Figure 5 As shown, the synchronizing ring 25 is located inside the rotating ring 23. The diameter of the synchronizing ring 25 is smaller than that of the rotating ring 23, and the synchronizing ring 25 and the rotating ring 23 are arranged on the same axis. The synchronizing ring 25 is arranged above the rotating ring 23 and is connected to the rotating ring 23 by welding.

[0037] like Figure 5 As shown, the rotating ring 23 can drive the synchronizing ring 25 to rotate synchronously when it rotates. The bracket assembly 5 is connected to the synchronizing ring 25, so the synchronizing ring 25 will drive the bracket assembly 5 and the condenser tube 41 on the bracket assembly 5 to rotate synchronously when it rotates.

[0038] like Figure 6-8 As shown, the rotating ring 23 is provided with multiple air outlet pipes 6. The rotating ring 23 has a corresponding through hole at the position of each air outlet pipe 6. The lower end of the air outlet pipe 6 is welded to the rotating ring 23. Each air outlet pipe 6 has a valve 61 at its top. The valve 61 is preferably connected to the air outlet pipe 6 by welding.

[0039] like Figure 6-8 As shown, each valve 61 is provided with a first diverter 62 at its outlet. The first diverter 62 is preferably connected to the diverter by means of threaded connection or flange connection. Therefore, after the valve 61 is opened, the gas inside the rotating ring 23 can be ejected through the first diverter 62.

[0040] like Figure 6-8 As shown, each first splitter 62 is provided with a copper connector 4. The lower end of the copper connector 4 is inserted into the first splitter, while the condenser tube 41 is located at one end of the copper connector 4 and is inserted into the copper connector 4.

[0041] like Figure 6-8 As shown, the end of the condenser tube 41 located inside the copper connector 4 is inserted into the first distributor 62, so the nitrogen gas sprayed through the first distributor 62 can enter the interior of the condenser tube 41 and the copper connector 4.

[0042] like Figure 9-11 As shown, the copper connector 4 is preferably made of copper or other materials. The copper connector 4 is circular and hollow inside. The function of the copper connector 4 is as a pipe splitter. The outer diameter of the first splitter 62 is the same as the inner diameter of the copper connector 4, so the copper connector 4 can be inserted into the first splitter 62.

[0043] like Figure 9-11 As shown, one end of the copper connector 4 is round, and the round end of the copper connector 4 is inserted into the first distributor 62. The shape of the other end of the copper connector 4 can be changed to a specific shape by stamping process to adapt to different numbers of condenser tubes 41, such as 2-way, 3-way or 4-way, etc.

[0044] like Figure 9-11 As shown, if the shape of the end of the copper connector 4 corresponds to two branches, then the ends of the two condenser tubes 41 can be inserted into the interior of the copper connector 4. If the copper connector 4 has two branches, then the exhaust ports at the top of the first distributor 62 corresponding to this two-branch copper connector 4 are also two. At the same time, the position of the exhaust port at the top of the first distributor 62 corresponds to the position where the condenser tubes 41 are inserted into the interior of the copper connector 4, thereby ensuring that the condenser tubes 41 can be correctly connected to the first distributor 62 after being inserted into the interior of the copper connector 4.

[0045] like Figure 9-11 As shown, if the shape of the end of the copper connector 4 corresponds to a branch of 3, then the ends of the three condenser tubes 41 can be inserted into the interior of the copper connector 4. If the copper connector 4 has 3 branches, then the top of the first distributor 62 corresponding to this 3-branch copper connector 4 also has three outlets. At the same time, the position of the outlet at the top of the first distributor 62 corresponds to the position where the condenser tubes 41 are inserted into the interior of the copper connector 4, and so on.

[0046] like Figure 9-11 As shown, after the condenser tube 41 is inserted into the copper connector 4, a welding process can be used to weld the gap between the end of the copper connector 4 and the condenser tube 41 together.

[0047] like Figure 12-18 As shown, the bracket assembly 5 includes a support rod 51, a support block 52, a clamping block 53, and a locking block 54. The support rod 51 is vertically positioned in the middle of the rotating ring 23 and the synchronizing ring 25. There are multiple support blocks 52, which are positioned on the same side of the support rod 51. The position of the support rod 51 corresponds to the position of the copper connector 4.

[0048] like Figure 12-18 As shown, the number of support blocks 52 on the support rod 51 is the same as the number of condenser tubes 41 inside the copper connector 4 corresponding to the support rod 51. If there are three condenser tubes 41 inside the copper connector 4, the number of support blocks 52 on the support rod 51 corresponding to this copper connector 4 is also three, and so on.

[0049] like Figure 12-18 As shown, the support blocks 52 are arranged along the height direction of the support rod 51. Two threaded holes 8 are opened at one end of the support block 52 on the support rod 51, and bolts 81 are provided in the threaded holes 8. The support rod 51 also has multiple threaded holes 8 along its height direction, and the specifications of the threaded holes 8 on the support rod 51 are the same as the specifications of the threaded holes 8 on the support blocks 52.

[0050] like Figure 12-18 As shown, after the end of the bolt 81 is passed through the threaded hole 8 on the support rod 51, the end of the bolt 81 can be turned into the threaded hole 8 on the support block 52, thereby connecting the support block 52 and the support rod 51 together.

[0051] like Figure 12-18 As shown, each support block 52 has a slot 55. One end of the condenser tube 41 is inserted into the copper connector 4, and the other end of the condenser tube 41 is suspended inside the slot 55 of the support block 52. The slots 55 on the multiple support blocks 52 connected to the support rod 51 are not in the same position, so as to accommodate condenser tubes 41 with different bending angles.

[0052] like Figure 12-18 As shown, when it is necessary to change the height of the support block 52, the height of the support block 52 can be changed through the threaded hole 8 on the support rod 51. Then, when it is necessary to change the specifications of the support block 52, the bolt 81 can be unscrewed and the new support block 52 can be connected to the support rod 51.

[0053] like Figure 12-18 As shown, the clamping block 53 and the locking block 54 are both located on the same side of the support block 52, and the clamping block 53 and the locking block 54 are respectively located above and below the synchronization ring 25. Two threaded holes 8 are opened at the center of the clamping block 53 and the locking block 54.

[0054] like Figure 12-18 As shown, the threaded holes 8 at the center of the clamping block 53 and the locking block 54 are arranged in the height direction of the clamping block 53 and the locking block 54, and the two threaded holes 8 at the center of the clamping block 53 and the locking block 54 are respectively arranged on the inner and outer sides of the synchronizing ring 25.

[0055] like Figure 12-18As shown, the clamping block 53 and the locking block 54 are both provided with grooves at the position of the synchronization ring 25. The clamping block 53 and the locking block 54 are clamped on the synchronization ring 25. Therefore, after the clamping block 53 and the locking block 54 are connected together by the bolt 81, the clamping block 53 and the locking block 54 can be clamped and fixed on the synchronization ring 25.

[0056] like Figure 12-18 As shown, the clamping block 53 is located at one end of the support rod 51 and has two threaded holes 8. The two threaded holes 8 of the clamping block 53 at one end of the support rod 51 are opened along the length direction of the clamping block 53. The support rod 51 has corresponding through holes at the positions of the threaded holes 8 at the ends of the clamping block 53.

[0057] like Figure 12-18 As shown, the clamping block 53 and the support rod 51 can be connected together by bolts 81. Washers 7 are provided on the top of the clamping block 53 and on the outside of the support rod 51 at positions corresponding to the end of the clamping block 53, so as to prevent the bolts 81 from loosening.

[0058] like Figure 12-18 As shown, after the clamping block 53 is connected to the support rod 51 and the locking block 54, the synchronizing ring 25 can drive the support rod 51 and the condenser tube 41 on the support rod 51 to rotate synchronously when it rotates.

[0059] like Figure 19-22 As shown, the gas supply device 3 includes a pressure sensor 31, a fixed housing 32, an air inlet pipe 33, a second distributor 34, a sealing ring 35, a gas guide pipe 36, and a signal valve 37. The pressure sensor 31 is located below the rotating ring 23 and is connected to the rotating ring 23 to measure the nitrogen pressure inside the rotating ring 23.

[0060] like Figure 19-22 As shown, the fixed shell 32 is located at the center of the base bracket 11 and is connected to the base bracket 11 by screws. The air intake pipe 33 is located below the fixed shell 32 and one end of the air intake pipe 33 is connected to the fixed shell 32.

[0061] like Figure 19-22 As shown, the fixed housing 32 has an opening at the position of the air inlet pipe 33, and the other end of the air inlet pipe 33 is provided with a signal valve 37. The end of the air inlet pipe 33 with the signal valve 37 is connected to a nitrogen pipeline. The second distributor 34 is located at the center of the rotating disk 22, and the lower end of the second distributor 34 is inserted into the interior of the fixed housing 32.

[0062] like Figure 19-22As shown, the second distributor 34 is connected to the rotating disk 22. The rotating disk 22 and the auxiliary gear 21 are both provided with through holes at the corresponding positions of the second distributor 34. Therefore, when the rotating disk 22 rotates, the second distributor 34 will rotate synchronously with the rotating disk 22.

[0063] like Figure 19-22 As shown, when the second distributor 34 rotates, the fixed housing 32 remains stationary. The sealing ring 35 is disposed inside the fixed housing 32 and fitted onto the second distributor 34, thereby sealing the gap between the fixed housing 32 and the second distributor 34 to prevent leakage.

[0064] like Figure 19-22 As shown, the sealing ring 35 is preferably a rotary sealing ring 35 to achieve dynamic sealing. There are four air guide pipes 36, all of which are arranged above the rotating disk 22. The four air guide pipes 36 are evenly arranged with the axis of the rotating disk 22 as the center, and one end of each of the four air guide pipes 36 is connected to the second distributor 34.

[0065] like Figure 19-22 As shown, the other ends of the four air guide pipes 36 are all connected to the third distributor 9 on the outside of the rotating ring 23. One end of the air intake pipe 33 is connected to the fixed shell 32, and the other end of the air intake pipe 33 is equipped with a signal valve 37.

[0066] like Figure 19-22 As shown, the signal valve 37 is preferably an electric ball valve or a butterfly valve. When the pressure sensor 31 detects that the internal pressure of the rotating ring 23 is too high, the signal valve 37 will close, and at this time the gas cannot enter the interior of the rotating ring 23 through the second distributor 34.

[0067] like Figure 19-22 As shown, when the pressure sensor 31 detects that the pressure inside the rotating ring 23 is too low, the signal valve 37 will open, and the gas can then enter the interior of the rotating ring 23 through the second distributor 34.

[0068] like Figure 19-22 As shown, four third distributors 9 and distributor pipes 91 are provided on the outer side of the rotating ring 23. The positions of the four third distributors 9 correspond to the positions of the four air guide pipes 36, and all four third distributors 9 are connected to the rotating ring 23. The air guide pipes 36 are connected to the air inlets of the third distributors 9.

[0069] like Figure 19-22 As shown, the third distributor 9 has a distributor pipe 91 at both ends. One end of the two distributor pipes 91 is connected to the gas outlet on the third distributor 9, and the other end of the two distributor pipes 91 is connected to the rotating ring 23. Therefore, the nitrogen gas that enters the third distributor 9 through the gas guide pipe 36 can enter the interior of the rotating ring 23.

[0070] The movement process in this embodiment is as follows: After the worker stands in the welding position, he inserts the copper connector 4 into the first distributor 62 and connects the two ends of the condenser tube 41 to the inside of the copper connector 4 and the slot 55 respectively. Then the worker can start the motor 13. After the motor starts, it can drive the rotating disk 22 to rotate through the main gear 14 and the auxiliary gear 21.

[0071] After the rotating disk 22 rotates to a specific angle, the motor 13 will turn off. At this time, the copper connector 4 and the condenser tube 41 waiting to be welded will be rotated to the position where the worker is welding. The worker can then open the valve 61 below the copper connector 4 to allow nitrogen gas inside the rotating ring 23 to enter the copper connector 4 and the condenser tube 41. The worker can then weld the condenser tube 41 and the copper connector 4 together. During the welding process, nitrogen gas will continuously spray out through the condenser tube 41 to prevent weld blockage. After the welding is completed, the copper connector 4 and the condenser tube 41 can be removed from the bracket assembly 5 for testing.

[0072] After the worker finishes welding the copper connector 4 and condenser pipe 41 in front of him, he can turn on the motor 13 to rotate the next copper connector 4 and condenser pipe 41 waiting to be welded to him, so that the welding can continue. Example 2

[0073] Based on Example 1, valve 61 is modified to be an electric valve 61, and a human proximity sensor 10 is provided at the position of each air outlet pipe 6 on the rotating ring 23.

[0074] like Figure 6-7 As shown, the human proximity sensor 10 is electrically connected to the electric valve 61. The electric valve 61 used is also a signal valve 37. When the rotating disk 22 rotates, it will rotate the electric valve 61 to the front of the worker for welding.

[0075] like Figure 6-7 As shown, the position of the human proximity sensor 10 corresponds to that of the electric valve 61. Therefore, when the electric valve 61 moves in front of the worker, the human proximity sensor 10 will also be rotated in front of the worker. When the human proximity sensor 10 detects that the worker is in front of it, the human proximity sensor 10 will move in front of the worker.

[0076] like Figure 6-7 As shown, the human proximity sensor 10 will send a signal to the electric valve 61 to open the electric valve 61. At this time, the nitrogen gas inside the rotating ring 23 can enter the copper connector 4 and the inside of the diverter 91 through the first diverter 62.

[0077] like Figure 6-7As shown, after welding is completed, motor 13 can be restarted to rotate the welded copper joint 4 and condenser pipe 41 out, and rotate the next copper joint 4 and condenser pipe 41 waiting to be welded to the front of the worker. When the human proximity sensor 10 detects that the worker in front has disappeared, it will close the corresponding electric valve 61 to prevent nitrogen from continuing to leak out.

[0078] The movement process in this embodiment is as follows: After the worker stands at the welding position and starts the motor 13 to rotate the copper joint 4 and the condenser pipe 41 waiting to be welded to the welding position, the human proximity sensor 10 below the copper joint 4 will start to enter the electric valve 61 of the welding position, so that nitrogen can be sprayed out from the condenser pipe 41 and the copper joint 4 at the welding position.

[0079] After welding is completed, the worker will start motor 13 to rotate the welded copper joint 4 and condenser pipe 41 out of the welding position. After the rotating disk 22 stops rotating, the human proximity sensor 10 will close the electric valve 61 when it detects that there is no worker in front of the copper joint 4, thereby preventing continuous nitrogen leakage.

[0080] The above embodiments are merely illustrative of the technical concept of the present invention and should not be construed as limiting the scope of protection of the present invention. Any modifications made to the technical solutions based on the technical concept proposed in this invention shall fall within the scope of protection of this invention.
