The power cylinder provides force for the insertion rod 331 to insert the O-ring and push the O-ring away from the insertion rod 331.

[0067] In some embodiments, an O-ring assembly mechanism and a method of use for pulling and positioning for welding machine manufacturing include: a transport mechanism 1, which is suitable for transporting a copper tube for a welding machine and is used to transport the copper tube for a welding machine to an assembly seat 2; an assembly seat 2, which is suitable for receiving the copper tube for a welding machine and serving as an assembly position for the copper tube for a welding machine and an O-ring, that is, the assembly steps of the copper tube for a welding machine and the O-ring are implemented here; a set mechanism 3, which includes a pulling component 31 and a set component 32, the pulling component 31 is suitable for pulling the O-ring to a set position, that is, pulling the provided O-ring to a position suitable for being inserted by the set component 32, so as to realize the transportation and precise positioning of the O-ring; the set component 32 is suitable for inserting the O-ring into the O-ring and inserting the O-ring into the copper tube for a welding machine of the assembly seat 2; this step is the assembly of the copper tube for a welding machine and the O-ring , a material channel 4, which includes a material trough 41 for receiving O-rings, which is used to serve as a channel for pulling O-rings; the conveying mechanism 1 is suitable for conveying the copper tubes and O-rings for welding machines assembled at the assembly seat 2, that is, conveying the assembled products to the material receiving position, and the material channel 4 is suitable for providing O-rings to the set mechanism 3; two feeding mechanisms 5, which are respectively used to provide copper tubes and O-rings for welding machines, that is, respectively provide copper tubes for welding machines to the conveying mechanism 1, and provide O-rings to the material trough 41 below the set mechanism 3; frame 6; the conveying mechanism 1 is suitable for conveying the copper tubes and O-rings for welding machines assembled at the assembly seat 2, and the material channel 4 is suitable for providing O-rings to the set mechanism 3; the conveying mechanism 1, the assembly seat 2, the set mechanism 3, the material channel 4 and the two feeding mechanisms 5 are all arranged at the frame 6, which are used to serve as support mechanisms for several of them.

[0068] In some embodiments, a method for using an O-ring assembly mechanism for pulling and positioning for welding machine manufacturing includes the following steps: step S1, wherein a feeding mechanism 5 provides a copper tube for a welding machine to a conveying mechanism 1 through a channel, and then the conveying mechanism 1 works to convey the copper tube for a welding machine to an assembly seat 2. During this process, a push rod of a vertical cylinder 12 extends to drive a clamping cylinder assembly 13 to approach the copper tube for a welding machine, and then the clamping cylinder assembly 13 clamps the copper tube for a welding machine and the vertical cylinder 12 resets. Then, the horizontal cylinder 11 works to drive the copper tube for a welding machine to the top of the assembly seat 2, and then the push rod of the vertical cylinder 12 extends again to drive the copper tube for a welding machine to the assembly seat, and then the clamping cylinder assembly 13 releases the copper tube for a welding machine. At this time, the conveying step of the copper tube for a welding machine is completed. At the same time, the O-ring provided by another feeding mechanism 5 reaches the limit assembly through a material trough 41, and the detection component here detects that the O-ring The O-ring is inserted into the groove 41 and the O-ring is pulled to slide in the material groove 41. It stops after reaching the set position, and then the pulling component 31 is moved away from the O-ring. Step S2: the set component 32 works. During this process, the power cylinder drives the insertion rod 331 to insert into the O-ring. At this time, the lower set component 34 provides support for the O-ring, and the insertion rod 331 passes through the end center hole of the lower set component 34. Further, the power cylinder is reset, and the set component 32 drives the O-ring to the top of the assembly seat 2.

[0070] In some embodiments, when the set assembly 32 is reset in step S3, the second cylinder pushes the push ring to move, and the push ring pushes the O-ring outside the insertion rod 331 away so that the O-ring remains in the copper tube for the welding machine; further, the first cylinder and the second cylinder are both reset, and then the set mechanism 3 is reset.

A method for using a pull-positioned O-ring assembly mechanism for welding machine manufacturing, characterized in that: The steps include: Step S1, one of the feeding mechanisms (5) provides the copper tube for the welding machine to the transport mechanism (1) through the channel, and then the transport mechanism (1) works to transport the copper tube for the welding machine to the assembly seat (2), and at the same time, the O-ring provided by the other feeding mechanism (5) reaches the limit assembly through the material groove (41), and then the pulling assembly (31) works to pull the O-ring to slide in the material groove (41) to reach the assembly position; Step S2, the set assembly (32) works, during which the power cylinder drives the insertion rod (331) to insert into the O-ring, further, the power cylinder is reset, the set assembly (32) drives the O-ring to reach the top of the assembly seat (2), and then the power cylinder works again to insert the O-ring into the copper tube for the welding machine, and at this time, the assembly of the O-ring and the copper tube for the welding machine is completed; Step S3, the set assembly (32) is reset, and the transport cylinder assembly (14) works to transport the assembled O-ring and the welding machine copper pipe to the material receiving position.

9. The method for using the pull-positioned O-ring assembly mechanism for welding machine manufacturing according to claim 8, characterized in that: When the insertion rod (331) is inserted into the O-ring in step S1, the lower sleeve (34) provides support force for the O-ring; The power cylinder comprises a first cylinder, a second cylinder and a push ring; when the insertion rod (331) is inserted into the O-ring in step S2, the first cylinder drives the second cylinder, the push ring and the insertion rod (331) to move, so that the insertion rod (331) is inserted into the O-ring.

10. The method for using the pull-positioned O-ring assembly mechanism for welding machine manufacturing according to claim 8, characterized in that: When the sleeve assembly (32) is reset in step S3, the second cylinder pushes the push ring to move, and the push ring pushes the O-ring outside the insertion rod (331) away, so that the O-ring remains in the copper tube for the welding machine; further, the first cylinder and the second cylinder are both reset, and then the sleeve mechanism (3) is reset.
