Therefore, the present invention is not limited to the following optional embodiments, but is defined only by the claims and their equivalents.

[0026] Example 1.

[0027] This embodiment provides a syringe processing device, such as... Figure 1 As shown, it includes:

[0028] The syringe 61 includes a needle, a syringe barrel 611, and a piston rod 612.

[0029] The clamping unit 11 clamps or releases the syringe 611 of the syringe 61 under the push of the first driving unit 21.

[0030] The second drive unit 22 is used to drive the piston rod 612 to move downward inside the syringe 611, thereby discharging the waste liquid inside the syringe 611.

[0031] The cutting unit 23 is used to cut the syringe 61, so that the needle and the syringe 611 are separated.

[0032] Driven by the third drive unit 24, each of the recycling bins 31-33 is positioned below the syringe 61 in sequence, thereby receiving waste liquid, needle and syringe 611 respectively.

[0033] To achieve automated processing, the syringe processing device further includes:

[0034] The first detection unit is used to detect whether the bottom end of the piston rod 612 reaches the bottom end of the syringe 611. When the bottom end is reached, the third drive unit 24 drives the first recycling bin 31 to move out of the lower side of the syringe and drives the second recycling bin 32 to move to the lower side of the syringe 61, and the shearing unit 23 works.

[0035] The second detection unit is used to detect whether the needle is separated from the syringe. When the needle is separated, the third drive unit 24 drives the second recovery container 32 to move out of the lower side of the syringe 61 and drives the third recovery container 33 to move to the lower side of the syringe 61. The first drive unit 21 releases the syringe 611.

[0036] To achieve automated processing, the syringe processing device further includes:

[0037] The third detection unit is used to detect whether the syringe 611 is separated from the clamping unit 11, and when separated, the third drive unit 24 drives the first recovery bucket 31 to move to the lower side of the syringe 61.

[0038] To enable rapid and accurate detection, the first detection unit is further configured to detect the resistance encountered by the second drive unit, and when the resistance exceeds a threshold, confirm that the bottom end of the piston rod has reached the bottom end of the syringe.

[0039] The second or third detection unit employs image recognition technology or photoelectric detection technology.

[0040] To achieve the clamping function, the clamping unit 11 further includes a horizontal guide rail 113, a first part 112 and a second part 111, the second part 112 being disposed on the horizontal guide rail 113, and the syringe 611 being clamped between the first part 112 and the second part 111.

[0041] In order to clamp and release the syringe 611, the first drive unit 21 is further configured to drive the second part 111 bidirectionally in the horizontal direction or push the second part 111 in the vertical direction to fix the second part 111 on the horizontal guide rail 113.

[0042] To facilitate the convenient and accurate placement of each recycling bin on the underside of the syringe 61, the third drive unit 24 further includes a motor and a turntable driven by it, with multiple recycling bins 31-33 arranged on the turntable.

[0043] The syringe processing device operates as follows:

[0044] Step 1: Place the syringe 61 under the second drive unit 22 and clamp it with the clamping unit 11;

[0045] Step 2: The second drive unit 22 pushes the piston rod 612 downward, and the piston rod 612 pushes the waste liquid in the syringe 611 out of the needle and drips into the first recovery bucket 31 set on the lower side of the syringe 61 until the end of the piston rod 612 moves to the bottom of the syringe 611.

[0046] Step 3: The cutting unit 23 cuts the syringe 61, the needle and syringe 611 separate, and fall into the second recycling bin 32 located on the lower side of the syringe 61;

[0047] Step 4: The clamping unit 11 releases the syringe 611, and the syringe 611 and piston rod 612 fall into the third recovery bin 33 located below the syringe 61.

[0048] To achieve automated processing, in step 2, when the end of the piston rod 612 is detected to have moved to the bottom of the syringe 611, the third drive unit 24 drives the first recovery bucket 31 to move out of the lower side of the syringe 61 and drives the second recovery bucket 32 ​​to move to the lower side of the syringe 61.

[0049] In step 3, after the needle is detected to have fallen, the third drive unit 24 drives the second recycling bin 32 to move out of the lower side of the syringe 61 and drives the third recycling bin 33 to move to the lower side of the syringe 61.

[0050] Example 2.

[0051] An application example of the syringe processing device in Embodiment 1 of this utility model.

[0052] In this application example, such as Figure 1 As shown, the syringe 61 includes a needle, a syringe barrel 611, and a piston rod 613.

[0053] The clamping unit 11 includes a horizontal guide rail 113, a first part 112, and a second part 111, which are respectively disposed on the horizontal guide rail 113. The adjacent ends of the first part 112 and the second part 111 are arc surfaces that match the syringe 611. Two first drive units 21 (electric telescopic mechanisms) are vertically disposed. When the first part 112 and the second part 111 clamp the syringe 611, and the first drive unit 21 pushes the first part 112 and the second part 111 downward, the first part 112 and the second part 111 are fixed on the horizontal guide rail 113, so that the first part 112 and the second part 111 clamp the syringe 611; when the first drive unit 21 releases, and the first part 112 and the second part 111 move away from each other, the syringe 611 falls.

[0054] The shearing unit 23 uses electric shears.

[0055] The second drive unit 22 is electrically driven, meaning that the first motor rotates to push the slider on the vertical guide rail to move up or down. When the slider moves down, it pushes the piston rod 612 down, and when the first detection unit detects that the rotational resistance of the first motor exceeds a threshold, it indicates that the end of the piston rod 612 has moved to the bottom of the syringe 611.

[0056] like Figure 2 As shown, the third drive unit 24 includes a second motor and a turntable driven by it. The first recycling bin 31, the second recycling bin 32 and the third recycling bin 33 are evenly arranged on the turntable. When the turntable rotates 120 degrees, the recycling bin is located under the syringe 61.

[0057] The second detection unit uses image recognition technology to identify whether the needle and syringe 611 are separated. The third detection unit uses image recognition technology to identify whether the syringe 611 is separated from the clamping unit 11.

[0058] The syringe processing device operates as follows:

[0059] Step 1: Place the syringe 61 under the second drive unit 22. The first part 112 and the second part 111 clamp the syringe 611. The two first drive units 21 push down on the first part 112 and the second part 111. The first part 112 and the second part 111 clamping the syringe 611 are fixed on the horizontal guide rail 113, so that the clamping unit 11 stably clamps the syringe 611.

[0060] Step 2: The second drive unit 22 pushes the piston rod 612 downward, and the piston rod 612 pushes the waste liquid in the syringe 611 out of the needle and drips into the first recovery bucket 31 located on the lower side of the syringe 61.

[0061] When the first detection unit detects that the rotational resistance of the first motor reaches a threshold, it indicates that the end of the piston rod 612 has moved to the bottom of the syringe 611, and the first motor stops rotating. The second motor drives the turntable to rotate, thereby driving the first recovery container 31 to move out of the lower side of the syringe 61, and driving the second recovery container 32 to move to the lower side of the syringe 61.

[0062] Step 3: The cutting unit 23 cuts the syringe 61, separating the needle from the syringe barrel 611, and the needle falls into the second collection container 32 located below the syringe 61. When the second detection unit detects that the needle has fallen, the third drive unit 24 drives the second collection container 32 to move out of the lower side of the syringe 61, and drives the third collection container 33 to move to the lower side of the syringe 61.

[0063] Step 4: The first drive unit 21 releases the first part 112 and the second part 111, causing them to separate on the horizontal guide rail 113, thereby releasing the syringe 611. The syringe 611 and the piston rod 612 fall into the third recovery container 33 located below the syringe 61. When the third detection unit detects that the syringe 611 has separated from the clamping unit 11, the third drive unit 24 drives the third recovery container 33 to move out of the lower side of the syringe 61 and drives the first recovery container 31 to move to the lower side of the syringe 61, preparing for the processing of the next syringe 61; the second drive unit 22 retracts upward.

[0064] Example 3.

[0065] The application example of the syringe processing device in Embodiment 1 of this utility model differs from Embodiment 2 in that:

[0066] The first drive unit (electric telescopic mechanism) is used to drive the first part and the second part to move horizontally, so that when the first part and the second part are close together, the syringe is clamped and when they are far apart, the syringe is released.

[0067] Examples 2-3 exemplify the use of image recognition technology in the second and third detection units. Alternatively, photoelectric detection technology can also be used. Specifically, a laser and a detector are respectively placed on the left and right sides below the needle tip. The detector receives the laser signal. When the signal received by the detector is less than a threshold, it indicates that the needle or syringe is blocking the laser beam, thus confirming whether the needle or syringe has fallen, achieving automatic and accurate identification.
