[0026] In order to make the purpose, technical scheme and advantages of the present application more clear and obvious, the present application will be further described in detail below with reference to the drawings.

[0027] As shown in Figure 1 and Figure 2 , a flexible water connector automatic assembly system, characterized in that it comprises an end mechanism 1, a module 2, a flexible tray 3, a cart 4, a cabinet 5, a display screen 6, an outer cover 7, a component feeding and discharging mechanism 8 and a water connector feeding mechanism 9.

[0028] As shown in Figure 2 , the module 2 is installed on the platform 51 at the top of the cabinet 5 through a support, wherein two sets of X-axis modules 23 are located at the lowermost layer and connected with the support, and are respectively located at both ends of the platform 51.

Since the vacuum generator 12, the cavity 117 and the wrench rod 118 are communicated through the pipeline, the negative pressure generated by the vacuum generator 12 can adsorb the water connector 119 to the lower end of the wrench rod 118. The electric wrench 111 drives the wrench rod 118 to rotate, so that the water connector 119 can be screwed and fixed in the mounting hole of the assembly 30. The industrial camera 14 is fixed with the bottom plate 13 through the camera support 15, and the light source 16 is fixed below the camera 14.

Subsequently, the horizontal moving cylinder 81 will retract, driving the flexible tray 3 to move inward along the tray guide rail 87 until the limit plate 33 on the flexible tray 3 contacts the limit screw 842, and the movement stops. At this time, the pushing force of the horizontal moving cylinder 81 will press the assembly 30 of the flexible tray 3 tightly on the limit plate 33, playing a role in fixing the position of the assembly 30.
