The male head 17 of the ring is pushed out by the male head push arm 3 and is buckled with the female head 22 at the end of the female head arc track 42.

[0049] like Figure 4 , 5 In this embodiment, the sleeve push arm device includes a male push arm 3 and a female push arm 2, both of which have the same internal structure and are arranged below the workbench 5 and symmetrically arranged on the left and right sides of the workstation. The structure of the sleeve push arm device includes a main body 14, and the main body 14 is provided with:

[0050] The rail channel 23 is used to accommodate the rail 39 of the collar and ensure that the rail 39 of the collar moves in the channel;

[0051] A push pin device, including a push pin 20, for pushing the male head 17 or the female head 22 of the collar out of the main body 14;

[0052] A cutting device for cutting the connection between the rail frame 39 of the collar and the male head 17 or the female head 22;

[0053] The feeding device is used to move the collar to drive the male head 17 or the female head 22 to continuously move to the end of the ejector pin 20 to achieve continuous feeding.

[0054] like Figure 6-10 In this embodiment, the needle pushing device and the feeding device are devices that cooperate with each other and are driven by a cylinder 11 externally connected to the main body 14.

[0055] In this embodiment, the push-pin device and the feeding device are arranged in the main body 14, and the main body 14 is provided with a pin 20 groove and a feeding device concave cavity 15. The pin 20 is arranged in the pin groove, and the feeding device is arranged in the feeding device concave cavity 15.

The upper and lower ends of the step connecting rod 27 are both provided with a protruding step surface 25, and the middle part is concave. The linkage block 26 is arranged at the concave part. When the linkage block 26 moves up and down, it can realize the action of pushing out or retracting the pin 20, and when the linkage block 26 touches the step surfaces 25 at the upper and lower ends of the step connecting rod 27, it drives the step connecting rod 27 to move up and down. ; The feeding device includes a positioning blade 32, a positioning blade seat 33, a feeding blade 30 and a feeding blade seat 29. The positioning blade seat 33 is arranged in the concave cavity 15 of the feeding device. The feeding blade seat 29 is rotatably fixed to one side of the positioning blade seat 33 through a rotating shaft 36, and the feeding blade seat 29 can rotate relative to the positioning blade seat 33 around the rotating shaft 36. The end of the feeding blade seat 29 is connected to the upper end of the step connecting rod 27 through a linkage hook 28. The positioning blade 32 is fixed on the positioning blade seat 33. The feeding blade seat 29 is provided with a spring hole. The lower end of the feeding blade 30 is provided with a limiting piece 38. The limiting piece 38 is arranged in the spring 34 hole. One end of the spring 34 abuts against the hole wall of the spring hole, and the other end abuts against the limiting piece 38 at the lower end of the feeding blade 30. The feeding blade 30 is rotatably fixed on the feeding blade seat 29. A spring 34 is provided between the feed blade 30 and the feed blade seat 29 so that when the blade rotates, the spring 34 contracts under the obstruction and reaction force of the rail frame 39, making it easier for the blade to pass through the slot on the rail frame 39 and also allowing the blade to automatically adapt to the distance of the rail frame 39.

[0056] In this embodiment, the upper ends of the feed blade 30 and the positioning blade 32 extend upward into the rail channel 23, the directions of the two blades are parallel to the direction of movement of the rail 39, and the feed blade 30 and the positioning blade 32 are provided with a slope, which is provided on the blade on the side facing the inlet end 19 of the rail channel 23; the device also includes a return lever 35, and the main body 14 is provided with a return lever channel 37 for accommodating the return lever 35, one end of the return lever 35 is connected to the positioning blade seat 33, and the other end is connected to the positioning blade seat 33. One end extends out of the main body 14 from the return lever channel 37; a spring 34 hole is provided at the lower end of the positioning blade seat 33, one end of the spring 34 rests on the hole wall of the spring 34 hole, and the other end rests on the cavity wall of the concave cavity 15 of the feeding device. A rotating shaft 36 is provided in the middle of the return lever 35, which rotatably fixes the return lever 35 in the return lever channel 37, and the other end of the return lever 35 extends into the positioning blade seat 33, so that the positioning blade seat 33 can be driven to float up and down when the return lever 35 is turned.

[0057] In this embodiment, the cutting device includes a cutting knife 16, which is arranged at the upper edge of the rail frame channel 23, and the position of the cutting knife 16 is directly opposite to the ejector pin 20. Only when it is directly opposite to the ejector pin 20, when the ejector pin 20 pushes up the male connector 17 or the female connector 22, the connecting line 40 between the rail frame 39 and the male connector 17 or the female connector 22 can be cut by the cutting knife 16.

[0058] In this embodiment, the upper part of the ejector pin 20 of the female push arm 2 is a tension spring 21; because when the device is used as a female push arm 2, a female arc track 42 is provided above the ejector pin 20, which is arc-shaped, so when the female 22 is sent into the female arc track 42, a flexible and bendable ejector pin is required, otherwise the action of sending the female 22 into the female arc track 42 cannot be achieved, and the tension spring 21 has the characteristics of being bendable without losing rigidity, and is very suitable for the front end of the ejector pin 20.

[0059] In this embodiment, an opening section 31 is provided on the upper part of the ejector pin 20 of the male push arm 3, and a male gun needle 6 is also provided on the main body 14 of the device. The male gun needle 6 is a hollow structure and has a channel for the ejector pin 20 inside. The direction of the male gun needle 6 is in a straight line with the ejector pin 20. The opening section 31 of the ejector pin 20 is stuck in the connection between the male connector 17 and the connecting line 40, and the male connector 17 cut off from the rail frame 39 is pushed out from the male gun needle 6.

[0060] In this embodiment, the inlet end 19 of the rail channel 23 is a straight section 18, and the outlet end 12 is a curved section 13. The transition section between the straight section 18 and the curved section 13 is located at the rear side of the cutting device, that is, after the male head 17 or the female head 22 of the collar is cut off from the rail 39, the rail 39 enters the transition section between the straight section 18 and the curved section 13 of the rail channel 23. The inner side surface of the main body 14 is also provided with a pressure cover 4, which presses the push pin device into the main body 14, and presses the cut rail 39 into the rail channel 23, so that the rail 39 is finally moved out from the outlet end 12 of the rail channel 23. Such a structural setting can ensure that the male head 17 or the female head 22 is first cut off from the rail 39 and pushed out of the main body 14, and then the remaining rail 39 is removed from the outlet end 12 of the rail channel 23. If the outlet end 12 is set to an arc shape, the rail frame 39 can be moved out from the bottom of the device and collected. If it is not an arc shape, the rail frame 39 will be perpendicular to the device and easily poke products elsewhere, which is inconvenient to use.

[0061] like Fig.11 In this embodiment, the female arc track assembly 1 includes a female arc track seat 8, a female arc track 42 arranged on the female arc track seat 8, and a slide cylinder 10.

[0068] E. The female head push arm cylinder 11 moves upward, pushing the female head ejector 20 to move above the workbench 5, and the female head 22 is separated from the rail frame 39 under the action of the cutting knife 16, and enters the female head circular arc track;

[0069] F. Under the control of the controller, the male push arm cylinder 11 works for 0.1s, and then the female push arm cylinder 11 moves upward, pushing the male ejector pin 20 to move above the workbench 5, and the male head 17 is separated from the rail frame 39 by the action of the cutting blade 16, and the male head 17 is pushed into the male gun needle 6;

[0070] G. The male head 17 and the female head 22 move forward under the action of the cylinder 11 until the cylinder 11 reaches the upper limit position and is buckled at the end point of the female head arc track;

[0075] Working description of the collar push arm device:

[0076] Taking the present device as the male push arm 3 as an example, the rail frame 39 enters from the inlet end 19 of the rail frame channel 23, the male head 17 is located at the side of the rail frame channel 23, the initial state of the piston 24 of the cylinder 11 is the retracted state, and the linkage block 26 is located at the lower end of the step connecting rod 27. When the piston 24 of the cylinder 11 extends, the ejector pin 20 first moves upward, and the opening section 31 of the ejector pin 20 wraps around the lower end of the male head 17 and pushes the male head 17 upward. When the connecting line 40 between the male head 17 and the rail frame 39 touches the cutting knife 16, the cutting knife 16 cuts the male head 17 off the rail frame 39; the piston 24 of the cylinder 11 continues to extend, and at this time, the male head 17 is pushed out of the ejector pin channel of the male gun needle 6 by the ejector pin 20. During the pushing process, the linkage block 26 moves upward to the upper end of the step connecting rod 27 and touches the upper step surface 25, driving the step connecting rod 27 to move upward. At this time, under the push of the linkage hook 28, the feed blade seat 29 rotates with the feed blade 30 toward the inlet end 19 of the rail channel 23, and the rotation angle is 15-20 degrees. When the feed blade 30 touches the rail 39. Since the feed blade 30 is provided with a slope toward the inlet end 19 of the rail channel 23 and a spring 34, the spring 34 is compressed, and the upper end of the feed blade 30 is lower than the height of the rail 39, so that the upper end of the feed blade 30 slides into the next slot. The piston 24 of the cylinder 11 is retracted, first driving the ejector 20 to retract. The piston 24 of the cylinder 11 continues to move downward, and the linkage block 26 moves downward to the lower end of the step connecting rod 27 and touches the lower step surface, driving the step connecting rod 27 to move downward. At this time, under the pull of the linkage hook 28, the feed blade seat 29 rotates and resets with the feed blade 30 toward the outlet end 12 of the rail channel 23, and then pulls the rail 39 to move toward the outlet end 12 of the rail channel 23. When the rail frame 39 and the connecting line 40 of the male head 17 touch the positioning blade 32 during movement, the positioning blade 32 is provided with a slope toward the inlet end 19 of the rail frame channel 23, and the lower end spring 34 of the positioning blade seat 33 is compressed, and the upper end of the positioning blade 32 is lower than the height of the rail frame 39, so that the glue needle can enter the designated position, that is, the next male head 17 moves to the top of the ejector 20, waiting to be pushed out of the main body 14. Since the positioning blade seat 33 is arranged in the concave cavity 15 of the feeding device, it is not driven by the cylinder, but is driven by the thrust of the sleeve glue needle, and the material is returned when it floats up and down by the material return lever. When the device is accidentally stuck, it only needs to turn the end of the material return lever 35 upward, and the material return lever 35 will drive the positioning blade seat 33 to move downward, realizing the action of manually returning the glue needle. Because a limit plate 38 is provided at the end of the feed blade 30, and the limit plate 38 is arranged in the hole of the spring 34, when the glue needle is subjected to a pulling force in the direction of the inlet end 19, this position contacts the hole of the spring 34 of the feed blade seat 29, so that the feed blade 30 is perpendicular to the workbench 5, and the glue needle is fixed at the position where feeding is required to prevent it from being pulled out from the inlet end 19.

[0077] The principle of the female push arm 2 is the same as that of the male push arm 3, but the direction is opposite.
