Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] This utility model provides an automatic assembly device for an air conditioner one-way valve, including a machine base 10. A circular base 20 is mounted on the machine base 10. An annular turntable 30, rotatable relative to the circular base 20, is arranged at equal intervals along its circumference on the annular turntable 30. The turntable 30 has valve body loading stations 21, valve core loading stations 22, valve seat loading stations 23, and valve unloading stations 24. The valve body loading station 21, valve core loading station 22, and valve seat loading station 24 are... At the valve seat feeding station 23, a valve body vibration feeding device 40, a valve core vibration feeding device 50, and a valve seat vibration feeding device 60 are respectively provided. At the valve core feeding station 22 and the valve seat feeding station 23, a clamping cylinder 211 and a transfer cylinder 212 are provided. An electric screwdriver bit 213 is provided above the clamping cylinder 211. The lower end of the electric screwdriver bit 213 is connected to a rotating rod 214. The electric screwdriver bit 213 is driven to move up and down by a lifting cylinder.

[0018] The valve body 1 is vibrated and fed onto the annular turntable 30 by the valve body vibration feeding device 40. Then, the annular turntable 30 is rotated 90 degrees so that the valve body 1 on the annular turntable 30 reaches the valve core feeding station 22. The head of the valve body 1 is clamped and fixed by the clamping cylinder 211. Then, the valve core 2 is vibrated and fed onto the valve body 1 by the valve core vibration feeding device 50. The valve core 2 is transferred to the top of the valve body 1 by the transfer cylinder 212 and placed into the valve body 1 and then reset. Then, the electric screwdriver bit 213 is driven to descend by the lifting cylinder so that the rotating rod 214 is inserted into the head of the valve core 2. The rotating rod 214 is driven to rotate by the electric screwdriver bit 21, so that the valve core 2 is connected to the valve body 1. The electric screwdriver bit 213 is reset by the lifting cylinder, and the annular turntable 30 is controlled to continue rotating 90 degrees. The head of the valve body 1 is clamped and fixed by the clamping cylinder 211 at the valve seat loading station 23. Then, the valve seat is loaded by the valve seat vibration loading device 60. The valve seat 3 is transferred to the top of the valve body 1 by the transfer cylinder 212 at the valve seat loading station 23 and placed on the valve body 1. The electric screwdriver bit 213 is driven to descend by the lifting cylinder, so that the rotating rod 214 is inserted into the head of the valve seat 3. The rotating rod 214 is driven to rotate by the electric screwdriver bit 21, so that the valve seat 3 is connected to the valve body 1. The annular turntable 30 is controlled to rotate 90 degrees and rotate to the unloading station 24 for unloading.

[0019] In this embodiment, valve body clamping assemblies are provided on the turntables 30 at the valve body loading station 21, valve core loading station 22, valve seat loading station 23, and unloading station 24. The valve body clamping assembly includes a base 31 and a support 32. The front end of the base 31 is provided with a slot for the valve body to be inserted. The support 32 is provided with a support rod 33 that can rotate relative to it and extends to the slot. A spring 34 is provided between the rear end of the support rod 33 and the support 32. When valve body 1 is fed to the annular turntable 30 by the valve body vibration feeding device 40, the front valve body 1 is pushed into the slot by the squeezing force of the rear valve body 1. During the pushing process, the support rod 33 rotates to overcome the elastic force of the spring 34 under the action of the squeezing force, so that the valve body 1 can be pushed into the slot smoothly. After being pushed in, the support rod 33 is reset under the action of the spring 34, and its front end will limit the valve body 1 in the slot, preventing the valve body 1 in the slot from falling out during the rotation of the annular turntable 30.

[0020] A photoelectric sensor for detecting whether the valve body is in position is also provided on the circular base 20 at a position corresponding to the valve body loading station 21. The photoelectric sensor is used to detect whether the valve body 1 has entered the slot of the base 31 of the valve body clamping assembly.

[0021] A pusher cylinder is provided at the unloading station 24. The front end of the pusher cylinder is provided with a pusher block for unloading. The V-shaped structure at the front end of the pusher block facilitates the unloading of the assembled one-way valve.

[0022] like Figure 7 As shown, the top of the valve core 2 is a flat protruding structure. Therefore, the bottom of the rotating rod 214 at the valve core loading station 22 is provided with a groove structure that can be inserted into the valve core head, so that the rotating rod 214 can drive the valve core 2 to rotate.

[0023] like Figure 8 As shown, the top of the valve seat 3 is provided with a groove structure, so the bottom of the rotating rod 214 at the valve seat loading station 23 is provided with a protrusion structure into which the nut head can be inserted, so that the rotating rod 214 can drive the valve seat 3 to rotate.

[0024] In summary, the automatic assembly device for one-way valves of air conditioners provided by this utility model achieves automated operation of the entire assembly process through automated loading and unloading, as well as automatic alignment and turning during the assembly process, thereby improving assembly efficiency and assembly accuracy.

[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
