[0069] The reciprocating moving assembly includes a second motor 7209, a disc 7210, a rocker arm 7211 and a second booster plate 7219. The second motor 7209 is connected to the second movable plate 7206 through the side plate 7208. The output shaft of the second motor 7209 is connected to the disc 7210. The second booster plate 7219 is arranged on the top surface of the second movable plate 7206. The disc 7210 is connected to the second booster plate 7219 through the rocker arm 7211. The rocker arm 7211 is eccentrically arranged with the disc 7210.

[0070] When the present invention is actually used, the control panel 5 is used to control the sensing mechanism 10, so that the sensing head 1006 is lowered to a desired height position under the action of the fifth cylinder 1005, and at the same time, the spacing adjustment plate 6204 on the fixture 62 is adjusted according to the size of the capillary bend and the spacing between the two capillary straight tubes;

[0071] Then, the capillary straight tube to be welded is manually placed on the fixture 62 so that the top of the capillary straight tube contacts the sensing head 1006. The sensing head 1006 generates a signal and feeds it back to the control panel 5. The control panel 5 controls the air valve control mechanism 9 to operate, so that the fourth air cylinder 904 drives the corresponding crank 64 on the box body 63 to move via the push rod 905, and controls the corresponding first air cylinder 6206 on the fixture 62 to operate, thereby clamping the capillary straight tube. Until both capillary straight tubes are installed, the fifth air cylinder 1005 drives the sensing head 1006 to separate from the capillary straight tube and move upward to the set position.

[0072] Then, a capillary bend is placed on the two capillary straight tubes, and the capillary is driven to rotate to the workstation of the second welding mechanism 8 by the turntable 61 to realize welding processing of the capillary bend and the capillary straight tube on one side;

[0073] The capillary is then driven by the turntable 61 to rotate to the first welding mechanism 7 to achieve welding processing of the capillary bend and the capillary straight tube on the other side;

[0074] After welding is completed, the turntable 61 is rotated to the next station for air cooling, and finally the welded capillary is taken out.

[0075] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements, or modifications based on the present invention to achieve substantially the same technical effects are included within the scope of protection of the present invention.
