Detailed Description
The present invention will be described in further detail below.
As shown in fig. 1 and 2, the fully automatic processing device for the medical syringe needle comprises a positioning jig 3, an upper cover plate assembly 2, a lower support plate assembly 4, a crimping assembly 5, a clamping device 6, a collecting assembly 7, a syringe sensor 8 and the like.
A needle head clamp is arranged below the positioning jig 3 and used for clamping the syringe needle head 11.
As shown in fig. 3-7, the crimping assembly 5 comprises a rotating means drivingly connected to the needle holder for driving the needle holder in a circumferential rotation for crimping the syringe needle 11; one side of the needle head clamp is correspondingly provided with a top block 513, and the top block 513 is fixedly connected to the positioning jig 3; the translation driving device is fixedly connected to the positioning fixture 3 and connected to the needle fixture, and is configured to drive the needle fixture to move toward the top block 513, so that the curled syringe needle 11 is separated from the needle fixture and falls off after being pushed against the top block 513.
When the medical injector positioning fixture is used, the waste medical injector 1 is placed in the positioning fixture 3 downwards, and the injector is positioned in the positioning fixture 3. After the needle holder holds the syringe needle 11, the rotating device drives the needle holder to rotate circumferentially, so that the syringe needle 11 is curled on the needle holder. When the crimp is reached to a certain extent, the syringe needle 11 is separated from the syringe barrel and the rotation means stops rotating. The translational drive then drives the needle holder towards the top block 513, so that the completely curled syringe needle 11 cannot move further with the needle holder after it has been pressed against the top block 513. As the needle holder continues to move, the needle holder is drawn away from the obstructed syringe needle 11, so that the syringe needle 11 falls downward, thereby achieving the automatic detachment of the syringe needle 11.

The channel in the positioning jig 3, which is adaptive to the outer diameter of the syringe cylinder, has a self-adaptive function, and when medical staff throw the medical syringe 1 into the positioning jig 3, the medical syringe 1 is automatically adjusted to be in a state that the syringe needle 11 is vertically downward in the positioning jig 3. The clamping size of the clamping device 6 below the channel is reduced to be slightly larger than the outer diameter of the syringe needle 11 in advance, when the medical syringe 1 slides from the channel of the positioning jig 3, the clamping device 6 clamps the syringe needle 11 and abuts against the lower end of the syringe needle, and the medical syringe 1 is hung in the clamping device 6 in a penetrating mode. The needle holder below the holding device 6 then holds the syringe needle 11 and starts to curl rotationally. Since the holding means 6 abuts against the lower end of the syringe barrel, the syringe needle 11 is separated from the syringe barrel as the syringe needle 11 is continuously curled. When the syringe needle 11 is released from the needle holder, the holding dimension of the holding device 6 is increased to be larger than the outer diameter of the syringe barrel, and the syringe barrel automatically drops downward from the holding device 6. The separated syringe needle cylinder is not required to be manually taken out of the positioning jig 3 to be discarded, and the operation is more convenient. The clamping device 6 can play a role in positioning the syringe needle 11, can also be propped against the syringe needle cylinder when the syringe needle 11 is pulled out, and provides fixing force for pulling out the syringe needle 11 by the needle clamp, so that the syringe needle 11 and the syringe needle cylinder are separated favorably.
