[0002] The air conditioning pipe is a dedicated connecting pipe between the outdoor unit and the indoor unit. The connecting pipe is filled with refrigerant.

[0003] In cooling mode, the indoor unit absorbs heat from the vehicle, turning the refrigerant into a low-pressure solid and then discharging it through a larger air conditioning pipe to the outdoor unit. The refrigerant is then compressed by the compressor, reaching a high temperature and high pressure before entering the outdoor unit's heat exchanger, where the fan rotates, releasing the heat. The refrigerant then returns to a moderate temperature and pressure before entering the vehicle through another air conditioning pipe.

[0004] After processing and forming, the air-conditioning pipes need to be placed in the predetermined workstation for cutting. When the air-conditioning pipes are moved to the predetermined position by the conveyor belt, they need to be transferred to the adjacent cutting and assembly stations. Due to limitations of site space and other factors, the air-conditioning pipes cannot be directly transferred from the conveyor belt to the adjacent cutting and assembly stations. On-site operators are required to perform manual operations, which has an adverse impact on the transportation efficiency of the air-conditioning pipes and urgently needs improvement.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] Please also refer to Figures 1 to 3The automatic transfer device for air-conditioning pipes provided by the present invention is now described. The automatic transfer device for air-conditioning pipes comprises a frame 1, a manipulator 2 and a drive mechanism 3, wherein the frame 1 comprises a top crossbeam 11 and a bottom crossbeam 12 corresponding to each other. The conveying direction of the air-conditioning pipe is the first horizontal direction. The top crossbeam 11 and the bottom crossbeam 12 both extend along the first horizontal direction. A first material carrier 121 for carrying the air-conditioning pipe is provided on the top of the bottom crossbeam 12. There are multiple first material carriers 121, and each first material carrier 121 is evenly arranged along the first horizontal direction. A second material carrier 122 is provided at the upstream end of the bottom crossbeam 12. The second material carrier 122 is used to carry the air-conditioning pipe. Connect the air-conditioning pipe from upstream; the manipulator 2 can grab the air-conditioning pipe located on the first loading tray 121 and the second loading tray 122, and the manipulator 2 has the freedom to move in the up and down directions and the first horizontal direction; the driving mechanism 3 includes a horizontal driving part and an up and down driving part, the horizontal driving part includes a screw nut assembly 31, and the up and down driving part includes a telescopic part 32 that can be telescopic up and down, the screw nut assembly 31 is provided on the top crossbeam 11, and can drive the telescopic part 32 to move in the first horizontal direction, the telescopic part 32 is provided at the power output end of the screw nut 313, and is used to drive the manipulator 2 to move up and down.

[0034] Compared with the prior art, the manipulator 2 in the above embodiment can grab the air-conditioning pipe, and move the air-conditioning pipe located in the second loading tray 122 to the first loading tray 121 during the up and down and horizontal movement, and then move the air-conditioning pipe located in the first loading tray 121 to other workstations (such as cutting and assembly stations) located downstream of the bottom beam 12, so as to realize the automatic transportation of the air-conditioning pipe on the conveyor line, and solve the technical problem of insufficient production efficiency of the air-conditioning pipe due to the lack of corresponding transfer devices in the existing air-conditioning production line; in addition to the above beneficial effects, the bottom beam 12 can be used to support the air-conditioning pipe, so that the holding height of the air-conditioning pipe during the transfer process is more reasonable, and the top beam 11 can cooperate with the driving mechanism 3 to drive the manipulator 2 to move along the up and down directions and the first horizontal direction.

[0035] Optionally, for the frame 1, in order to fix the relative positions of the top beam 11 and the bottom beam 12, the frame 1 also includes a column 13 and a supporting frame 14. The bottom beam 12 is arranged on the supporting frame 14, and the bottom end of the column 13 is connected to the top of the supporting frame 14, and the top end is connected to the top beam 11. In this way, the column 13 can fix the top beam 11 on the supporting frame 14, and the supporting frame 14 can fix the above-mentioned column 13 and the top beam 11 while fixing the bottom beam 12, so that the entire frame 1 forms a frame structure, thereby improving the overall structural rigidity of the frame 1.

[0036] As a preferred embodiment, in the specific implementation, the telescopic part 32 is set to a telescopic cylinder, which includes a cylinder body and a telescopic rod. The cylinder body is connected to the power output end of the screw and nut assembly 31, and the telescopic rod is telescopically arranged in the cylinder body along the up and down directions, and the end of the telescopic rod outside the cylinder body is connected to the manipulator 2. In this embodiment, the screw and nut assembly 31 can drive the telescopic cylinder to move along the first horizontal direction, and then drive the manipulator 2 to move by the up and down extension of the telescopic cylinder. In this way, the manipulator 2 can transfer the air-conditioning pipe mentioned above only by opening and closing its own jaws, thereby realizing the automatic transfer of the air-conditioning pipe between the conveying station and the processing station.

[0037] As a preferred embodiment, the screw and nut assembly 31 includes a driving screw 311, a guide rod 312, and a nut 313. The driving screw 311 and the guide rod 312 are both arranged on the top crossbeam 11. The driving screw 311 and the guide rod 312 both extend along the first horizontal direction. The nut 313 is provided with a threaded hole and a guide hole. The threaded hole is threadedly adapted to the driving screw 311, and the guide hole is slidably adapted to the guide rod 312. In this embodiment, as the driving screw 311 rotates, the nut 313 is guided and moved along the first horizontal direction, thereby driving the telescopic cylinder to move, thereby realizing the movement of the manipulator 2 in the first horizontal direction. In addition, the transmission between the driving screw 311 and the nut 313 is more precise, which can realize the precise positioning of the manipulator 2 in the horizontal direction and prevent the manipulator 2 from misaligning with the air conditioning pipe.

[0038] As a preferred embodiment, in detail, the first material carrier 121 is a plurality of materials arranged at intervals along the first horizontal direction, the manipulator 2, the telescopic cylinder and the nut 313 are a plurality of materials arranged at intervals along the first horizontal direction, and the manipulator 2, the telescopic cylinder and the nut 313 correspond one to one from bottom to top, so as to improve the transportation efficiency of the air-conditioning pipe in this embodiment.

[0039] A feasible embodiment is proposed in which the screw and nut assembly 31 described above further includes a connecting frame for securing the nuts 313. The top crossbeam 11 defines a slot extending longitudinally along a first horizontal direction. The connecting frame is engaged with the slot and can slide along the first horizontal direction. With this arrangement, this embodiment can secure the relative positions of the nuts 313 via the connecting frame, thereby limiting the relative positions of the manipulators 2 and preventing them from wandering.

[0040] Since the overall structure of the connecting frame occupies a large space and is inconvenient for repairing a single nut 313, in order to solve the above problem, a feasible implementation method is proposed. Specifically, the top beam 11 is provided with a plurality of positioning grooves 110 that are respectively slidably adapted to each nut 313. The length direction of the positioning groove 110 is parallel to the first horizontal direction. The nut 313 is clamped in the positioning groove 110, and the nut 313 can slide along the first horizontal direction. The positioning groove 110 is provided with a pad 111 near both ends. The pad 111 is lockable on the inner wall of the positioning groove 110 along the first horizontal direction, and the nut 313 is located between the two pads 111. A feasible embodiment is proposed, in which a tension spring 112 is further provided in the positioning groove 110. The tension spring 112 can be stretched along a first horizontal direction. Any spacer 111 is provided with a countersunk hole for accommodating the tension spring 112. One end of the tension spring 112 is connected to the bottom of the countersunk hole, and the other end is connected to the nut 313. The tension spring 112 is in a contracted state within the countersunk hole, and in a stretched state stretched by the nut 313. In this embodiment, when the tension spring 112 pulls the nut 313, the connection between the nut 313 and the drive screw 311 can be tightened, reducing the transmission gap between the nut 313 and the screw, and improving the transmission accuracy between the nut 313 and the screw. At the same time, the tension spring 112 can always keep the nut 313 in contact with the spacer 111 where the spring is located through its own tension, thereby achieving the technical effect of returning the nut 313 to zero. In addition, the spacer 111 can prevent the nut 313 from being directly installed in the positioning groove 110 , which is beneficial for maintaining the sliding accuracy between the nut 313 and the positioning groove 110 .

[0041] Based on the same inventive concept, the present invention also proposes an assembly production line for air-conditioning pipes, which includes the above-mentioned automatic station transfer device for air-conditioning pipes.

[0042] Compared with the prior art, the assembly production line of the air-conditioning pipe in the present invention has all the advantages of the above-mentioned automatic transfer device for the air-conditioning pipe, which will not be described here.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
