Specifically, the magnetic attraction device 300 and the pilot valve 500 are attracted by the intelligent control, so that the phenomenon that the magnet attraction process is required to be manually performed on the pilot valve 500 of each air conditioner in the conventional air conditioner outdoor unit evacuation process is effectively avoided, and the efficiency of the air conditioner outdoor unit evacuation operation in the production process is improved; meanwhile, the air conditioner is in a heating mode by the automatic reversing of the four-way valve 600, and then the evacuation operation is performed on the port E of the four-way valve 600, so that the evacuation equipment 400 is directly communicated with the condenser side, and thus, the evacuation effect of the outdoor unit of the air conditioner is effectively improved; in addition, the large valve at the E-shaped opening is used for evacuating the interior of the air conditioner outdoor unit, the caliber of a communicated pipeline is large, and the evacuation efficiency of the air conditioner outdoor unit can be effectively improved.
Specifically, in order to realize the suction operation between the magnetic suction device 300 and the pilot valve 500, the position information of the pilot valve 500 is obtained first. It should be understood that the position information of the pilot valve 500 includes not only two-dimensional information of the pilot valve 500, but also three-dimensional information of the pilot valve 500. Then, the magnetic attraction device 300 is attracted to the pilot valve 500, so that the magnetic attraction device 300 is attracted to the pilot valve 500. Finally, evacuation processing is performed on port E of four-way valve 600 by evacuation device 400. So, cancelled traditional manual magnetism and inhaled process of pilot valve 500, inhale the operation through intelligent control magnetism, shortened the time of inhaling the operation of inhaling, effectively improved air condensing units's production efficiency.

Referring to fig. 2, in one embodiment, the specific steps of acquiring the position information of the pilot valve 500 include:
acquiring first image information of the pilot valve 500 through a first camera 110, and simultaneously acquiring second image information of the pilot valve 500 through a second camera 120, wherein the first camera 110 and the second camera 120 are arranged side by side;
and reconstructing the three-dimensional image information of the pilot valve 500 by using a triangulation principle according to the pixel point parallax of the first image information and the second image information to obtain the position information of the pilot valve 500.
In this embodiment, the step of acquiring the position information of the pilot valve 500 is optimized. Specifically, at least two image information acquiring devices are provided to acquire two-dimensional image information of the pilot valve 500, and then three-dimensional image information of the pilot valve 500 is calculated by reconstructing the acquired image information.
The relative positions of the first camera 110 and the second camera 120 are fixed, so that two-dimensional image information of the pilot valve 500 at least two different positions can be acquired from two different perspectives of the first camera 110 and the second camera 120. Then, the plane coordinates of the pilot valve 500 on the first camera 110 and the second camera 120 are obtained, and the position information of the pilot valve 500 is obtained through calculation by combining the relative positions of the first camera 110 and the second camera 120.

In this embodiment, the evacuation procedure of the air conditioner outdoor unit in the production process is further optimized. Specifically, the position information of the air conditioner outdoor unit on the production line is firstly acquired, and when the air conditioner outdoor unit moves to a specified position, the position of the air conditioner outdoor unit is fixed, so that a stable operation environment is provided for the evacuation operation, and the evacuation effect is improved.
In order to further explain the evacuation method of the outdoor unit of the air conditioner of the present disclosure, the technical solution provided in this embodiment is described below with reference to application scenarios.
It should be noted that the outdoor unit of the air conditioner needs to be filled with a sufficient amount of refrigerant before leaving the factory, and needs to be vacuumized before being filled with the refrigerant; in addition, before leaving a factory, the on-line pipe and the refrigeration pipeline of the indoor unit need to be filled with nitrogen for anti-oxidation protection, and the air conditioner also needs to be pumped out and then filled with nitrogen. The vacuumizing/evacuating operation needs to discharge non-condensable gas and water which affect the operation effect of the air conditioner in a pipeline of an air conditioning system, so that the lubricating oil and the water are prevented from acting to generate acid for corroding a copper pipe; in addition, copper ions are prevented from dissociating in the refrigerant after the copper pipe is corroded and being replaced by iron when passing through the compressor, so that the phenomenon of copper plating is avoided, and the compressor is prevented from being damaged; meanwhile, the phenomena that the refrigerant cannot normally circulate and the air conditioner cannot normally work due to icing in the valve port of the expansion valve or in the capillary tube caused by mixing water into the refrigerant are avoided.
Therefore, in the production process of the air conditioner outdoor unit, the position information of the air conditioner outdoor unit on the production line is firstly obtained, and when the air conditioner outdoor unit reaches the designated position opening, the position of the air conditioner outdoor unit is fixed, so that the position fixing of the pilot valve 500 is realized. Then, the first camera 110 acquires first image information of the pilot valve 500, and simultaneously acquires second image information of the pilot valve 500 through the second camera 120, and reconstructs three-dimensional image information of the pilot valve 500 by using a triangulation principle through parallax of pixel points of the first image information and the second image information to acquire spatial position information of the pilot valve 500. Then, the magnetic attraction device 300 is controlled to be attracted to the pilot valve 500 according to the spatial position information of the pilot valve 500, and the magnetic attraction device 300 can change the capillary tube communication path inside the pilot valve 500, so as to change the communication condition of each tube port of the four-way valve 600, specifically, in this embodiment, the D port and the E port of the four-way valve 600 are mainly controlled to be communicated, and the S port and the C port are communicated, so that the four-way valve 600 is in the heating mode. Finally, the evacuation device 400 is communicated with the port E of the four-way valve 600, and the evacuation device 400 is controlled to evacuate the port E, because the port E in the heating mode is directly communicated with the side of the condenser, the condenser can be directly evacuated, and the situations of poor evacuation effect, low evacuation efficiency and the like caused by the fact that the air-evacuated body needs to be communicated with the condenser through a capillary tube, an expansion valve and other thin pipelines are avoided.

Meanwhile, the evacuation device 400 is provided, the evacuation device 400 at least comprises a vacuum pump and a connecting pipeline, and the pipeline is communicated with the large valve at the E port of the four-way valve 600, so that the vacuum pump is communicated with the internal pipeline of the air conditioner, and when the pneumatic vacuum pump is used for pumping air, pumping/discharging of gas and moisture in the air conditioner can be realized.
