It is characterized by a trumpet-shaped joint for sealing at the end of the insulation pipe, a copper nut for tightening the joint connection, an insulation sleeve to reduce heat exchange losses, and a protective plug before the connecting pipe is unsealed and put into use. Based on the characteristics and features of the metal connecting pipe of the indoor and outdoor units of the air conditioner, the existing production of the metal connecting pipe of the indoor and outdoor units of the air conditioner is still in the production mode of manual operation and semi-automatic equipment auxiliary operation.

[0068] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0069] See also Figure 1 The present application provides a new technical solution: a processing equipment and process method for a heat-insulating metal pipe, including a cutting guide unit, a displacement pipe-threading device 7, a transplanting and loading and unloading unit, a reciprocating conveying device 11, a heat-insulating metal pipe assembly unit, a sorting and sorting unit and a visual inspection unit;

[0070] The material cutting guide unit comprises a metal tube material cutting guide device and a thermal insulation cotton tube material cutting guide device, and the metal tube material cutting guide device and the thermal insulation cotton tube material cutting guide device are used to respectively guide the metal tube and the thermal insulation cotton tube raw materials and cut them into the forming size of the thermal insulation metal tube;

[0071] The displacement pipe-threading device 7 is used to compositely thread the cut metal pipe and the insulation cotton pipe to form an insulation metal pipe;

[0072] The transplanting loading and unloading unit includes a transplanting loading device 8 and a transplanting unloading device 15. The heat-insulating metal pipe docks the displacement pipe-piercing device 7 and the reciprocating conveying device 11 through the transplanting loading device 8, so that the heat-insulating metal pipe is transplanted to the reciprocating conveying device 11. The reciprocating conveying device 11 and the sorting and sorting unit are docked through the transplanting unloading device 15, so that the formed heat-insulating metal pipe is transported to the sorting and sorting unit.

[0073] The insulation metal pipe assembly unit is located on both sides of the reciprocating conveyor 11, and is used to form and process both sides of the insulation metal pipe and assemble copper nuts and protective plugs to complete the overall assembly of the insulation metal pipe. The assembled insulation metal pipe is transported to the sorting unit through the transplanting and unloading device 15 and the reciprocating conveyor 11 to sort qualified and unqualified products;

[0074] The visual inspection unit includes a metal tube defect inkjet visual inspection system 19 and a bell mouth defect visual inspection system 20, and the metal tube defect inkjet visual inspection system 19 and the bell mouth defect visual inspection system 20 respectively perform defect inspection on the metal tube and the bell mouth of the metal tube.

[0075] In some embodiments, see Figure 2-4 The metal tube cutting guide device comprises a metal tube cutting guide frame 2, a metal tube cutting machine cutting device 3 and a guide assembly device 4;

[0076] In this example, see Figure 2The metal tube cutting guide frame 2 includes a frame 1 and a guide tube 21, which is used to unwind the copper tube coil raw material and guide it to the metal tube cutting machine cutting device 3 for straightening and fixed-length cutting; when in use, first, fix the rolled metal tube (steel tube coil 22) on the cutting guide frame. Usually, the cutting guide frame will have a central axis, and the steel tube coil 22 is sleeved on this axis and fixed. By rotating the central axis, the rolled metal tube is gradually unfolded. The function of the guide tube 21 is to provide a smooth path during the unfolding of the metal tube, prevent the metal tube from twisting or tying when unfolding, and ensure the quality of the metal tube cutting.

[0077] In this example, see Figure 3 The metal tube cutting machine cutting device 3 includes a metal tube straightening component 31, a tube feeding mechanism 32, a breaking mechanism assembly 33 and a chipless cutting blade assembly 34. The metal tube unrolled by the metal tube cutting guide frame 2 is guided and conveyed to the metal tube straightening component 31 for straightening. The straightened metal tube is conveyed to the chipless cutting blade assembly 34 and the breaking mechanism assembly 33 by the tube feeding mechanism 32 for fixed-length cutting. The cut metal tube is installed with a guide end through a guide assembly device 4 to prevent damage to the insulation cotton tube. When in use, the unrolled metal tube is first straightened by the metal tube straightening component 31 to eliminate bending and deformation and ensure that the metal tube is straight. Then the tube feeding mechanism 32 clamps the straightened metal tube and prepares for feeding. The tube feeding mechanism 32 clamps the metal tube The tube is pushed forward 1.5 meters, the tube feeding mechanism 32 releases the metal tube, stops feeding, and returns to its original position. The tube feeding mechanism 32 clamps the metal tube again, and the tube feeding mechanism 32 pushes the metal tube forward 1.5 meters again. The tube feeding mechanism 32 releases the metal tube again, stops feeding, and returns to its original position again. The breaking mechanism assembly 33 clamps the metal tube and prepares for cutting. The chipless cutting head assembly 34 is started to cut the metal tube. The breaking mechanism assembly 33 pulls the metal tube to complete the cutting action and break the metal tube. The breaking mechanism assembly 33 continues to maintain the clamping state to prevent the metal tube from moving. The breaking mechanism assembly 33 releases the metal tube and prepares for the next operation. The tube feeding mechanism 32 returns to its original position and prepares for the next feeding.

[0078] In this example, see Figure 4 The guide assembly device 4 includes a silo 41, a staggered mechanism 42, a transverse mechanism 43, a lifting mechanism 44 and a grasping mechanism 45, which are used to assemble the guide end head to the side where the metal tube and the thermal insulation cotton tube are composited; when in use, the lifting mechanism 44 grabs the guide head, the lifting mechanism 44 descends, and moves the guide head to the assembly position of the metal tube end head, the transverse mechanism 43 is started, and the guide head is horizontally moved to one side of the metal tube end head, the grasping mechanism 45 is opened, and the guide head is installed to one side of the metal tube through the transverse mechanism 43.

[0079] In some embodiments, see Figure 5-6 The thermal insulation cotton tube cutting guide device comprises a thermal insulation cotton tube cutting guide frame 5 and a thermal insulation cotton tube cutting and cutting device 6;

[0080] In this example, see Figure 5 The insulation cotton tube cutting guide frame 5 at least includes a guide wheel 51, which is used to unfold the rolled insulation cotton tube and guide it to the insulation cotton tube cutting and cutting device 6 for fixed-length cutting; when in use, the insulation cotton roll 52 is installed on the central axis and fixed by a clamping device. By rotating the central axis, the insulation cotton roll 52 is gradually unfolded, and the insulation cotton tube passes through the guide wheel 51. The guide wheel 51 ensures that the insulation cotton tube is unfolded straight to avoid twisting and knotting. After passing the guide wheel 51, the insulation cotton tube enters the cotton feeding mechanism 61 of the insulation cotton roll 52 cutting machine. The cotton feeding mechanism 61 clamps the insulation cotton tube and transports it forward to the cutting station.

[0081] In this example, see Figure 6 The thermal insulation cotton tube cutting device 6 includes a cotton feeding mechanism 61, a movable cotton clamping mechanism 62, a cutter assembly 63 and a fixed cotton clamping mechanism 64, which are used to cut the thermal insulation cotton tube to a fixed length in accordance with the cutting length of the metal tube; when in use, the movable cotton clamping mechanism 62 and the fixed cotton clamping mechanism 64 are closed to clamp the unrolled thermal insulation cotton tube. To ensure that the thermal insulation cotton tube remains stable during the cutting process, the cutter assembly 63 is started to cut the clamped thermal insulation cotton tube to a fixed length. The cutter assembly 63 is driven by a motor, and the high-speed rotating blade quickly cuts the insulation cotton tube to ensure that the cutting surface is flat and free of burrs. After the cutting is completed, the movable cotton clamping mechanism 62 and the fixed cotton clamping mechanism 64 are opened to release the insulation cotton tube. At this time, the insulation cotton tube is cut into the required length. The cotton feeding mechanism 61 clamps the cut insulation cotton tube and transports it forward for a distance. Before the insulation cotton tube is inserted into the metal tube, the movable cotton clamping mechanism 62 tightens one end of the insulation cotton tube. The tightening mechanism slightly expands the end of the insulation cotton tube mechanically or pneumatically so that it can be more easily inserted into the metal tube.

[0082] In some embodiments, see Figure 7 The displacement tube-piercing device 7 includes a cotton pulling mechanism 71, an expansion mechanism 72, a displacement mechanism 73, a transverse displacement mechanism 74, a clamping mechanism 75 and a longitudinal displacement mechanism 76;

[0083] The rotating displacement mechanism 73 is used to rotate the insulation cotton tube to a predetermined position corresponding to the metal tube. The cotton pulling mechanism 71 moves to one end of the insulation cotton tube and clamps the insulation cotton tube. The insulation cotton tube and the metal tube are compounded by the longitudinal movement mechanism 76 and the transverse displacement mechanism 74, and the rotating displacement mechanism 73 is rotated again to make the compounded insulation metal tube fall onto the transplanting and feeding device 8.

[0084] The expansion mechanism 72 is used to expand the end of the thermal insulation cotton tube so that the metal tube can be more easily inserted into the thermal insulation cotton tube.

[0085] When in use, the shifting mechanism 73 first rotates the thermal insulation cotton tube to a predetermined position to ensure that it is aligned with the metal tube, and the cotton pulling mechanism 71 moves to the end position of the thermal insulation cotton tube to prepare for clamping the thermal insulation cotton tube. The cotton pulling mechanism 71 clamps one end of the thermal insulation cotton tube to prepare for subsequent pulling, and the longitudinal movement mechanism 76 begins to pull the thermal insulation cotton tube to gradually move it toward the metal tube. The distance changing mechanism adjusts the spacing between the thermal insulation cotton tubes as needed to adapt to metal tubes of different lengths, and continues to pull the thermal insulation cotton tube to ensure that it gradually enters the metal tube. The expansion mechanism 72 expands the port of the thermal insulation cotton tube to make it easier for the metal tube to penetrate into the thermal insulation cotton tube. The metal tube smoothly penetrates into the thermal insulation cotton tube under the action of the expansion mechanism 72, and the spacing between the thermal insulation cotton tubes is adjusted again to ensure that the composited thermal insulation metal tubes are neatly arranged. The rotating shifting mechanism 73 rotates again to adjust the angle of the thermal insulation metal tube to ensure that it is correctly dropped. The composited thermal insulation metal tube falls into the transplanting and loading device 8 through the dropping device, ready to enter the next processing station.

[0086] In some embodiments, see Figure 8 and Fig.15 The transplanting loading device 8 and the transplanting unloading device 15 both include a lifting platform, a conveying mechanism and a power system, which are used to load and unload materials to the reciprocating conveying device 11;

[0087] When the transplanting and feeding device 8 is in use, the feeding lifting platform 83 rises to a height that is docked with the displacement pipe-threading device 7, the feeding conveying mechanism 81 clamps the insulated metal pipe and conveys it forward for a distance, and the feeding lifting platform 83 descends to a height that is docked with the reciprocating conveying device 11, and the feeding conveying mechanism 81 continues to convey the insulated metal pipe to the reciprocating conveying device 11, and the reciprocating conveying device 11 clamps the insulated metal pipe and transfers it to the next processing station.

[0088] When the transplanting unloading device 15 is in use, the unloading lifting platform 153 rises to a height that is docked with the reciprocating conveying device 11, the unloading conveying mechanism 151 clamps the finished product and conveys it forward a distance, and the unloading lifting platform 153 descends to a height that is docked with the sorting and material handling device, and the unloading conveying mechanism 151 continues to transport the finished product to the sorting and material handling device.

[0089] In some embodiments, see Fig. 9 The reciprocating conveying device 11 includes a fixed fixture 111, a movable fixture 112 and a transmission system 113. The fixed fixture 111 and the movable fixture 112 clamp the heat-insulating metal pipe and convey it through the transmission system 113, so as to transfer the heat-insulating metal pipe between the processing and assembly stations of the heat-insulating metal pipe assembly unit;

[0090] When in use, the fixed clamp 111 opens to release the insulated metal tube, the movable clamp 112 closes to clamp the insulated metal tube, the transmission system 113 drives the movable clamp 112 and the insulated metal tube clamped by it to move to the next workstation, the fixed clamp 111 closes to clamp the insulated metal tube, the movable clamp 112 opens to release the insulated metal tube, and the transmission system 113 drives the movable clamp 112 back to its original position to prepare for the next transportation.
