Wherein, the O-ring is a sealing ring for air conditioner compressor. The O-ring automatic feeding mechanism comprises: vertical turntable, horizontal screw rod and horizontal material receiving channel. The vertical turntable is provided with at least two horizontal screw rods along its circumferential direction. The horizontal screw rod has screw rod groove, and the groove width of the screw rod groove is greater than the thickness of the O-ring, so that the O-ring can be hung inside the screw rod groove. When the horizontal screw rod is displaced to the horizontal material receiving channel directly above by the vertical turntable, at this time, the O-ring hung can be driven to advance by rotating the horizontal screw rod, until falling into the horizontal material receiving channel.

The screw rod groove of the screw rod first straight section is relatively compactly distributed, and the screw rod groove of the screw rod gradually expanding and gradually tapering section and the screw rod second straight section is relatively loosely distributed.

[0007] As the preferred scheme of the O-ring automatic feeding mechanism, the end of the horizontal material receiving channel is provided with an inner supporting movable claw, when the falling O-ring reaches the position of the inner supporting movable claw, the inner supporting movable claw positions the falling O-ring.

[0008] As the preferred scheme of the O-ring automatic feeding mechanism, it further comprises: compression ring, the inner diameter of the compression ring is greater than the outer diameter of the O-ring, the thickness of the compression ring is greater than the groove width of the screw rod groove, and the compression ring is hung outside the screw rod groove.

[0009] Compared with the prior art, the O-shaped ring is driven to advance by the transverse screw rod, automatic feeding is realized, and feeding efficiency is improved. Each transverse screw rod is sequentially fed by the vertical turntable, and the frequency of stopping and loading is reduced.

[0012] Fig. 2 It is a structural schematic view of the transverse material receiving channel of the embodiment of the utility model. DETAILED DESCRIPTION

[0013] The utility model will be further described in detail in combination with the drawings through specific implementation manners. It needs to be explained here that the description of these implementation manners is used to help understand the utility model, but does not constitute the limitation to the utility model. In addition, the technical features involved in each implementation manner of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0014] Referring to Figs. 1-2 , it is an O-shaped ring automatic feeding mechanism shown in the figure, replacing the traditional manual feeding. Among them, the O-shaped ring is an air conditioner compressor sealing ring, and the diameter is 100mm. The O-shaped ring automatic feeding mechanism comprises a fixed rack 1, a vertical turntable 2, a transverse screw rod 3 and a transverse material receiving channel 4 and the like. The vertical turntable 2 is arranged on the fixed rack 1. The vertical turntable 2 is erected. The vertical turntable 2 can rotate around its axis. In specific implementation, the back of the vertical turntable 2 has a turntable motor. The vertical turntable 2 is in transmission connection with the motor shaft of the turntable motor. The vertical turntable 2 is driven to rotate by the turntable motor.

[0015] Four transverse screw rods 3 are arranged on the front of the vertical turntable 2 along the circumferential direction thereof. The axis of the vertical turntable 2 is parallel to the axis of the transverse screw rod 3. The vertical turntable 2 is used to specify that one of the transverse screw rods 3 is displaced to the vertical above the transverse material receiving channel 4.

[0016] The transverse screw 3 has screw grooves. The groove width of the screw grooves is greater than the thickness of the O-ring 100. The O-ring 100 is suspended inside the screw grooves. When the transverse screw 3 is located directly above the transverse material receiving channel 4, the transverse screw 3 drives the O-ring 100 to move along the transverse screw 3 by rotating around its axis until the O-ring 100 falls off the transverse screw 3 and drops into the transverse material receiving channel 4. In actual implementation, the back of the vertical turntable 2 is provided with a screw motor. The transverse screw 3 is in transmission connection with the motor shaft of the screw motor. The screw motor drives the transverse screw 3 to rotate.

[0017] The whole feeding process is as follows: the vertical turntable 2 first specifies one of the transverse screws 3 to move to the position directly above the transverse material receiving channel 4 for feeding. When the feeding is completed, the vertical turntable 2 specifies the next transverse screw 3 to move to the position directly above the transverse material receiving channel 4 for feeding. Until all the four transverse screws 3 complete the feeding, the machine stops to load materials, so as to reduce the frequency of stopping to load materials.

[0018] Further, the transverse screw 3 has sequentially connected screw first straight section 31 (import section, loading section), screw gradually expanding and gradually shrinking section 32 (transition section, the outer diameter is first expanded and then shrunk) and screw second straight section 33 (export section, feeding section). The screw first straight section 31 and the screw second straight section 33 have the same or basically the same outer diameter. The screw grooves of the screw first straight section 31 are relatively compactly distributed, while the screw grooves of the screw gradually expanding and gradually shrinking section 32 and the screw second straight section 33 are relatively loosely distributed. The above design aims to control the falling rhythm. Further, it also includes a compression ring 5. The thickness of the compression ring 5 is greater than the groove width of the screw grooves. The compression ring 5 is suspended outside the screw grooves. The inner diameter of the compression ring 5 is greater than the outer diameter of the O-ring 100. The compression ring 5 is used to align the O-ring 100. The O-ring 100 can pass through the compression ring 5. In order to prevent the compression ring 5 from falling, front and rear limiting supports 6 in fixed positions are further included. The compression ring 5 is between the front and rear limiting supports 6.

[0019] Further, the end of the transverse material receiving channel 4 is provided with an inner supporting movable claw 41. When the dropped O-ring 100 reaches the position of the inner supporting movable claw 41, the inner supporting movable claw 41 supports and positions the dropped O-ring 100, and waits for the material taking mechanism to take the material.

[0020] The above only expresses the embodiment of the utility model, the description is more specific and detailed, but and therefore cannot be understood as the restriction of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, a number of variations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
