(45) When the condenser is vertically installed by the second clamping jaw 26, a telescopic end of the thirty-fifth air cylinder 92 moves downwards, such that the sliders of the two seventh linear guide rails 93 move downwards, so as to drive the slide guide plate 94 to move close to the climatic conditioning cabinet. Then, the thirty-sixth air cylinder 95, the thirty-seventh air cylinder 96 and the thirty-eighth air cylinder 97 drive the plurality of guide plates for condenser to extend out, such that the guide plates for condenser abut against the condenser, thereby guiding the condenser to ensure the assembly accuracy of the condenser.

(46) With reference to FIG. 16, the connection assembly for pipe heads of the evaporator and condenser 10 includes a support frame body, a pipe clamping element of the evaporator and condenser, a hexagon nut tightening unit and a compression element for sponge. Both the support frame body and the hexagon nut tightening unit are mounted on the operation frame body, and the pipe clamping element of the evaporator and condenser and the compression element for sponge are disposed on the support frame body. The pipe clamping element of the evaporator and condenser may clamp the pipes of the evaporator and the condenser, the hexagon nut tightening unit may tighten the hexagon nuts for connecting the pipe heads of the evaporator and the condenser, and the compression element for sponge may compress a sponge, against the pipe heads of the evaporator and the condenser.

(47) The pipe clamping element of the evaporator and condenser includes a thirty-ninth air cylinder 101, a fortieth air cylinder 102, a second upper clamping block 103 and a second lower clamping block 104. The thirty-ninth air cylinder 101 is fixedly connected to the support frame body in horizontal direction, and the fortieth air cylinder 102 extends vertically downwards and is fixedly connected to a telescopic end of the thirty-ninth air cylinder 101. The second upper clamping block 103 is fixedly connected to a cylinder body of the fortieth air cylinder 102, and the second lower clamping block 104 is fixedly connected to a telescopic end of the fortieth air cylinder 102. When the telescopic end of the thirty-ninth air cylinder 101 extends out, the fortieth air cylinder 102 may extend out. When the telescopic end of the fortieth air cylinder 102 retracts, the second upper clamping block 103 and the second lower clamping block 104 may move close to each other, so as to clamp the pipes of the evaporator and the condenser, to facilitate tightening the hexagon nuts and sticking the sponge.

(48) The hexagon nut tightening unit includes a forty-first air cylinder 105, a forty-second air cylinder 106, a forty-third air cylinder 107, a forty-fourth air cylinder 108 and a second screw gun 109. The forty-first air cylinder 105 extends vertically upwards and is fixedly connected to the operation frame body, the forty-second air cylinder 106 is fixedly connected to a telescopic end of the forty-first air cylinder 105 in horizontal direction by a support frame, and the forty-second air cylinder 106 extends toward the assembly line 5. The forty-third air cylinder 107 is fixedly connected to a telescopic end of the forty-second air cylinder 106 in horizontal direction, and the forty-third air cylinder 107 and the forty-second air cylinder 106 are perpendicular to each other. The forty-fourth air cylinder 108 is fixedly connected to a telescopic end of the forty-third air cylinder 107 and extends toward the assembly line 5. The extension or retraction direction of a telescopic end of the forty-fourth air cylinder 108 is consistent with the extension or retraction direction of the telescopic end of the thirty-ninth air cylinder 101. The second screw gun 109 is fixedly connected to the telescopic end of the forty-fourth air cylinder 108 by the support frame. When the telescopic ends of the forty-first air cylinder 105, the forty-second air cylinder 106, the forty-third air cylinder 107 and the forty-fourth air cylinder 108 extend out or retract, the position of the second screw gun 109 may be correspondingly adjusted, so as to tighten the hexagon nuts.

(49) Based on the same concept, the present application further provides an assembly process for evaporator and condenser on a climatic conditioning cabinet.

(50) The assembly process for evaporator and condenser on the climatic conditioning cabinet includes the following steps:

(51) After the climatic conditioning cabinet is conveyed to a station by an assembly line 5, square nuts are provided by a vibration feeding part for square nut, and the square nuts are mounted on the climatic conditioning cabinet by a fifth clamping jaw 718. Then, a first clamping jaw 24 on a mechanical arm clamps an evaporator to a secondary positioning part for evaporator for secondary positioning, and then clamps the evaporator and conveys it to an assembly part for evaporator, which then pushes the evaporator horizontally into the climatic conditioning cabinet, where the evaporator is guided by a plurality of auxiliary assembly parts for evaporator in the pushing process.

(52) Then, pipe clamps are provided by a vibration feeding part for pipe clamp, then, bolts are driven into the climatic conditioning cabinet by a first screw gun 714, so that a pipe of the evaporator is positioned by the pipe clamps. Then, a second clamping jaw 26 on the mechanical arm clamps a condenser and conveys it to a secondary positioning part for condenser for secondary positioning and then clamps and pushes the condenser into the climatic conditioning cabinet, where the condenser is guided by a guide unit for condenser 9 in the pushing process.

(53) Then, pipes of the condenser and the evaporator are clamped by a pipe clamping element of the evaporator and condenser, hexagon nuts are mounted to the connection between the pipe heads of the evaporator and the condenser by a second screw gun 109, and then, sponge is compressed against the connection between the pipe heads of the evaporator and the condenser by a compression element for sponge.

(54) The above descriptions are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent variations made according to the structure, shape and principle of the present application shall fall within the protection scope of the present application.
