The frame 10 is provided with a clamp head, which can clamp the needle of the infusion set. In order to improve work efficiency, the wire tube grabbing device 20, the wire tube winding device 30, the wire tube pushing device 40, the automatic bag feeding device 50, the transfer bag holding device 60 and the packaging device 70 are arranged on the same frame 10 in two sets.

[0033] The wire tube grasping device 20 is used to grasp the needle of the infusion set connected to the frame 10, and includes a lateral moving mechanism 2, an up-down lifting mechanism 2, a pneumatic finger 3 801 and a mechanical gripper 21. The lateral moving mechanism 2 is arranged on the frame 10, and the up-down lifting mechanism 2 is connected to the lateral moving mechanism 2 and moves with it, that is, the lateral moving mechanism 2 can drive the up-down lifting mechanism 2 to move horizontally. The pneumatic finger 3 801 is connected to the up-down lifting mechanism 2, and can move up and down with the up-down lifting mechanism 2; the mechanical gripper 21 is fixed on the pneumatic finger 3 801 and is controlled to open and close by it. During operation, the up-down lifting mechanism 2 controls the mechanical gripper 21 to descend to the workbench 11, and the pneumatic finger 3 801 controls the mechanical gripper 21 to close, allowing it to grab the needle; after grabbing, the up-down lifting mechanism 2 drives the mechanical gripper 21 to rise, and driven by the horizontal moving mechanism 2, it moves to the top of the bayonet 391 of the wire tube winding device 30. At this time, the up-down lifting mechanism 2 controls the mechanical gripper 21 to move downward, allowing the needle to be clamped on the bayonet 391; after clamping, the pneumatic finger 3 801 controls the mechanical gripper 21 to release, and then returns to its original position driven by the up-down lifting mechanism 2 and the horizontal moving mechanism 2 to perform the next operation.

[0034] The wire tube winding device 30 uses the positioning end of the infusion set as a fulcrum, and drives the tube winding rod 31 to rotate through a servo motor to wind the infusion set. Its structure is as follows: it includes a lower positioning plate 38, a lower push servo motor 32, a lower slide seat 33, a ball screw 34, a lower rotation servo motor 35, a lower turntable 36, an upper turntable 37, a tube winding rod 31 and a positioning rod 39. The lower positioning plate 38 is fixed to the bottom of the frame 10, the lower push servo motor 32 is fixed to the lower positioning plate 38, and its upper rotating shaft is connected to the ball screw 34. The lower seat 33 is screwed on the ball screw 34 and moves with the rotation thereof. The lower rotation servo motor 35 is fixed to the lower seat 33 and moves with it, and the lower turntable 36 is connected to the rotating shaft of the lower rotation servo motor 35. The upper end of the positioning rod 39 has a bayonet 391 that cooperates with the mechanical gripper 21, and the lower end thereof is inserted into the center of the lower turntable 36 and rotates in place with the lower turntable 36; the tube winding rod 31 is located on both sides of the positioning rod 39 and rotates in a circle with the lower turntable 36; the upper turntable 36 is rotatably arranged in the workbench 11 of the frame 10, and has a through hole on it for the tube winding rod 31 and the positioning rod 39 to pass through. When working, the lower push servo motor 32 drives the lower slide seat 33 to move up, and the lower rotating servo motor 35 on the fixed lower slide seat 33 will also move up together, which drives the tube winding rod 31 and the positioning rod 39 to move up, so that they extend out of the upper surface of the upper turntable 37; when the mechanical gripper 21 clamps the needle on the bayonet 391, the lower rotating servo motor 35 works to rotate the tube winding rod 31 to circle the line tube of the infusion set. In order to make the wire tube tighter after winding, a tube pressing device is provided on the workbench 11, which is composed of a support 111, a pressure plate 112, a telescopic cylinder 1 (not shown in the figure), a return spring 113 and a vertical rod 114. The support 111 is fixed on the workbench 11, and the pressure plate 112 is hinged on the support 111 through a pin shaft; the vertical rod 114 stands upright on the support 111, one end of the return spring 114 is connected to the pressure plate 112, and the other end thereof is connected to the vertical rod 114, and the cylinder rod 44 of the telescopic cylinder 1 cooperates with the pressure plate 112. During operation, the telescopic cylinder controls the cylinder rod to retreat, and under the pulling force of the return spring 113, the pressure plate 112 rotates inward until its rear end abuts against the support 111 (after the rear end of the pressure plate 112 abuts against the support 111, its further rotation can be restricted); when winding the tube, the infusion set passing through the pressure plate 112 will be knocked, and after repeated knocking, the wire tube of the infusion set can be wound tighter to prevent it from loosening and opening after winding the tube.

[0035] The wire tube pushing device 40 is used to clamp the conveyor after winding and push it into the packaging bag, and then push it together with the packaging bag to the transfer bag holding device 60; it includes a transverse moving mechanism three 401, an up and down lifting mechanism three, a left pneumatic finger 41, a right pneumatic finger 42, a left gripper 43, a right gripper 44, a pushing pipe 45 and a pushing mechanism 46.

The pushing pipe 45 is used to position the infusion set after winding, and push it to the transfer bag holding device 60 through the pushing mechanism 46. Its structure is as follows: it is through front and back and has an opening 451 that passes through both ends at the upper end. The opening 451 is a travel channel for the left gripper 43 and the right gripper 44. The rear end of the pushing pipe 45 has a through slot 452. The slot 452 is located opposite to the rear end opening in upper and lower directions, and a clamping channel is formed therebetween to position the packaging bag on the transfer bag holding device 60. During operation, the up-and-down lifting mechanism 3 drives the left gripper 43 and the right gripper 44 to descend. When their bottom end faces contact the upper end face of the tube winding rod 31, the lower rotating servo motor 35 drives the tube winding rod 31 and the left gripper 43 and the right gripper 44 to descend synchronously. When the left gripper 43 and the right gripper 44 contact the end face of the workbench 11 (the tube winding rod 31 descends to the inside of the upper turntable 37), the left pneumatic finger 41 and the right pneumatic finger 42 respectively control the left gripper 43 and the right gripper 44 to clamp the two ends of the infusion set. At this time, the horizontal moving mechanism 3 401 pushes it into the pushing pipe 45.

During operation, the bag feeding slide plate 56 slides to the bottom of the bag storage box 51, and the second suction cup 811 is pushed by the second lower bag suction cylinder 521 to absorb the packaging bag at the bottom of the bag storage box 51. In order to prevent multiple bags from being absorbed at one time, the packaging bags are demagnetized before being placed in the bag storage box 51; after absorption, the second suction cup 811 moves downward and moves to the right below the upper connecting plate 55 under the push of the bag feeding slide plate 56, and the second upper bag suction cylinder 531 pushes the upper connecting plate 55 downward, so that the second suction cup 811 on it absorbs the upper surface of the packaging bag, and then the second upper bag suction cylinder 531 moves upward, so that the bag mouth of the packaging bag can be in an open state.
