DETAILED DESCRIPTION

[0024] The following will combine the embodiments of the present utility model to clearly and completely describe the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present utility model.

[0025] like Figure 1-7 As shown, a technical solution is provided below:

[0026] A needle-puncture-proof shrapnel feeding and assembling device comprises a feeding mechanism 1, a material preparation mechanism 2, a transfer mechanism 3 and an assembly mechanism 4. The feeding mechanism 1 is used to feed the shrapnel 5 to the material preparation mechanism 2, and a gripper is installed on the transfer mechanism 3. The transfer mechanism 3 is used to install the shrapnel 5 on the material preparation mechanism 2 to the assembly mechanism 4. The assembly mechanism 4 comprises an opening and closing air claw 11, a guide needle 25, a support guide block 10 and a telescopic slide 20. The support guide block 10 is used to install the shrapnel 5. The support guide block 10 is arranged at the center of the opening and closing air claw 11. The opening and closing air claw 11 is provided with a needle threading guide slot. The guide needle 25 is arranged on the telescopic slide 20. The guide needle 25 is slidably connected with the guide slot. The through hole 15 on the shrapnel 5 is opposite to the guide slot. The needle guide slot includes a lower guide slot 17 and an upper guide slot 18. The lower guide slot 17 and the upper guide slot 18 are respectively arranged on the head and tail sides of the spring piece 5. The lower guide slot 17 is arranged on the side of the opening and closing air claw 11 close to the guide needle 25, and the puncture needle is arranged in the upper guide slot 18.

[0027] A spring stopper 21 is fixedly installed on the telescopic slide 20, and a guide pin 25 support block 22 is provided at the telescopic end of the telescopic slide 20. The guide pin 25 is installed on the guide pin 25 support block 22. A compression spring 24 is connected between the spring stopper 21 and the guide pin 25 support block 22, and a displacement sensor 23 is installed on the spring stopper 21.

[0028] It also includes a slideway and an assembly servo module 26. The assembly servo module 26 slides along the slideway. A mounting block 27 is provided on the assembly servo module 26. A slider mounting plate 29 is provided on the mounting block 27 through a lifting cylinder 30. An air gripper mounting plate 28 is installed on the slider mounting plate 29. An opening and closing air gripper 11 is provided on the mounting plate. The opening and closing air gripper 11 includes two left and right guide jaws 12. A protrusion 16 is provided on the side of the guide jaw 12 facing the spring sheet 5. The two protrusions 16 are used to squeeze the spring sheet 5 to open the spring sheet 5. A guide block 19 is provided on one guide jaw 12, and a guide groove opposite to the guide block 19 is provided on the other guide jaw 12. Both guide jaws are provided on the servo module.

[0029] The material preparation mechanism 2 includes a material preparation block 6, a material placement groove is provided on the material preparation block 6, the head end 13 of the opening of the spring piece 5 is inserted into the material placement groove, and the tail 14 extends out of the material placement groove. A material arrival detection optical fiber 8 is installed on the side wall of the material placement groove, and a vent hole 7 is provided on the side wall of the material placement groove near the head end 13, and the vent hole 7 is connected to the vacuum tube. The material preparation mechanism 2 also includes a material preparation platform, and the spring piece 5 and the material preparation block 6 are slidably connected to the material preparation platform through the material preparation servo module 9.

[0030] Implementation principle: the shrapnel 5 is transported to the shrapnel 5 preparation block 6 of the preparation mechanism 2 through the feeding mechanism 1, and the arrival detection optical fiber 8 detects whether the shrapnel 5 is transported to the specified position. A vacuum pipe joint is installed at the vent 7 to provide vacuum, which is used to adsorb the head end 13 of the shrapnel 5 to prevent the shrapnel 5 from falling off during transfer. The slider of the preparation servo module 9 moves to the loading position, and the transfer mechanism 3 clamps the tail 14 of the shrapnel 5 and places the shrapnel 5 on the shrapnel 5 support guide block 10 of the shrapnel 5 assembly mechanism 4. When the left and right guide jaws 12 installed on the opening and closing air claws 11 are closed, the protrusions 16 in the middle of the guide jaws 12 squeeze the two side pieces of the shrapnel 5, so that the head ends 13 of the two side pieces of the shrapnel 5 are opened, and the left and right guide jaws 12 are positioned with each other by the guide block 19 and the guide groove to ensure that after the guide jaws 12 are closed, the lower end guide slot hole 17 and the upper end guide slot hole 18 of the center of the guide jaws 12 are in the same straight line with the through hole 15. The operation causes the telescopic end of the telescopic slide 20 to extend, driving the head of the guide needle 25 through the lower end guide slot 17, through the through hole 15 and the head end 13 of the spring 5, and into the upper end guide slot 18. The assembly servo module 26 is actuated, so that the mounting plate installed on the assembly servo module 26 drives the entire assembly to move toward the servo end of the assembly servo module 26. During the movement, the tail 14 of the puncture needle tube pushes the head of the guide needle 25 through the upper end guide slot 18 until the tail 14 of the puncture needle tube passes through the through hole 15 and enters the lower end guide slot 17. When the guide needle 25 retreats, the tail 14 compresses the stainless steel compression spring 24. When the displacement sensor 23 detects that the tail 14 of the guide needle 25 has reached the specified position, the assembly servo module 26 stops moving, and the telescopic slide 20 retracts. The opening and closing air claw 11 opens, thereby driving the guide clamping claw 12 to open, the two side pieces of the spring sheet 5 rebound, and the head end 13 closes and clamps the puncture needle tube. The opening and closing air claw 11 is installed on the air claw mounting plate 28, and the air claw mounting plate 28 is linked with the lifting cylinder 30 through the slider mounting plate 29. The lifting cylinder 30 retracts, driving the opening and closing air claw 11 downward, and the spring sheet 5 is separated from the spring sheet 5 supporting guide block 10 and hung on the tail 14 of the puncture needle tube. The slider of the assembly servo module 26 returns to the initial position, and the lifting cylinder 30 extends, thereby realizing the feeding and assembly of the puncture needle and the spring sheet 5.
