The operation is relatively simple, and it is convenient to place the needle cap 6 in the position to be assembled in an orderly manner.

[0030] Working principle:

[0031] When using the safety retractable self-destructive syringe assembly machine to assemble the safety retractable self-destructive syringe, the syringe 10 to be assembled is placed in the groove provided in the disc 9, the electric push rod 12 is started, and the output end of the electric push rod 12 is fitted with the syringe 10 to position the syringe 10;

[0032] Needle cap placement phase:

[0033] The needle cap 6 to be assembled is placed inside the hopper 404, and the vibration motor 405 is started. The vibration motor 405 drives the hopper 404 to vibrate, and the hopper 404 drives the second slider 402 to move. The second slider 402 slides on the outer wall of the third slide bar 401. The second slider 402 and the third slide bar 401 guide the movement of the hopper 404. The spring 403 makes the movement of the hopper 404 more stable under the elastic action. When the needle cap inside the hopper 404 vibrates, it falls out from the lower end of the hopper 404 and falls into the interior of the material box 5 for assembly. The operation is relatively simple, and it is convenient to place the needle cap 6 in the position to be assembled in an orderly manner.

[0034] Assembly stage:

[0035] The second servo motor 8 drives the disc 9 to rotate, and then drives the syringe 10 to rotate, so that the syringe 10 is in the assembly position, and the first servo motor 301 is started. The first servo motor 301 drives the roller 302 to rotate, and the roller 302 drives the vertical rod 303 to move through the internal slide groove. The first slide bar 304 guides the movement of the vertical rod 303, and the vertical rod 303 drives the push rod 305 to move. The first slide bar 306 and the second slide bar 307 guide the movement of the push rod 305. The push rod 305 pushes the needle cap 6 at the bottom of the material box 5 out and buckles it on the outer wall of the needle of the syringe 10, realizing the assembly of the safe retractable self-destructive syringe. During assembly, the needle is not likely to accidentally injure the staff, which facilitates the assembly of the syringe. When the first servo motor 301 continues to start, the push rod 305 returns to the initial position, and the second servo motor 8 controls the disc 9 to rotate, rotating the unassembled syringe 10 to the assembly position. When the assembled syringe 10 rotates to the left, it is removed and replaced with the unassembled syringe 10.
