[0018] The shearing unit 23 is used to shear off the syringe 61 so that the needle and the syringe 611 are separated.

[0019] Driven by the third driving unit 24 , each recovery barrel 31 - 33 is sequentially located at the lower side of the syringe 61 , thereby receiving waste liquid, a needle and a syringe 611 respectively.

[0020] In order to realize automated processing, the syringe processing device further includes: 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, and send a first control instruction to the controller when reaching the bottom end; The second detection unit is used to detect whether the needle is separated from the syringe, and send a second control instruction to the controller when separated; The controller is used to control the third drive unit 24 according to the first control instruction, thereby driving the first recovery bucket 31 to move out from the lower side of the syringe, and driving the second recovery bucket 32 ​​to move to the lower side of the syringe 61, and controlling the shearing unit 23 to work; and controlling the third drive unit 24 according to the second control instruction, thereby driving the second recovery bucket 32 ​​to move out from the lower side of the syringe 61, and driving the third recovery bucket 33 to move to the lower side of the syringe 61, and controlling the first drive unit 21 to release the syringe 611.

[0021] In order to realize automated processing, the syringe processing device further includes: The third detection unit is used to detect whether the syringe 611 is separated from the clamping unit 11, and send a third control instruction to the controller when separated; The controller is used to control the third driving unit 24 according to the first control instruction, so as to drive the first recovery barrel 31 to move to the lower side of the syringe 61 .

[0022] In order to detect quickly and accurately, further, the first detection unit is used to detect the resistance encountered by the second driving unit and output a first control instruction when the resistance exceeds a threshold value; The second detection unit or the third detection unit adopts image recognition technology or photoelectric detection technology.

[0023] In order 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 is arranged on the horizontal guide rail 113 , and the syringe 611 is clamped between the first part 112 and the second part 111 .

[0024] In order to clamp and release the syringe 611 , further, the first driving unit 21 is used to drive the second part 111 in both directions in the horizontal direction, or to push the second part 111 in the vertical direction to fix the second part 111 on the horizontal guide rail 113 .

[0025] In order to conveniently and accurately arrange each recovery barrel on the lower side of the syringe 61, further, the third driving unit 24 includes a motor and a turntable driven by the motor, and the plurality of recovery barrels 31-33 are arranged on the turntable.

[0026] The syringe processing method of the embodiment of the present invention, that is, the working method of the syringe processing device, comprises the following steps: Step 1: Place the syringe 61 on the lower side of the second driving unit 22 and clamp it by the clamping unit 11; Step 2, the second driving unit 22 pushes the piston rod 612 downward, and the piston rod 612 pushes the waste liquid in the syringe 611 to be discharged from the needle and drip into the first recovery bucket 31 arranged at the lower side of the syringe 61 until the end of the piston rod 612 moves to the bottom end of the syringe 611; Step 3, the shearing unit 23 cuts off the syringe 61, and the needle and the syringe 611 are separated and fall into the second recovery bucket 32 ​​arranged at the lower side of the syringe 61; Step 4: The clamping unit 11 releases the syringe 611 , and the syringe 611 and the piston rod 612 fall into the third recovery bucket 33 disposed at the lower side of the syringe 61 .

[0027] In order to realize the automated processing, further, in step 2, after detecting that the end of the piston rod 612 moves to the bottom end of the syringe 611, the controller controls the third driving unit 24, thereby driving the first recovery barrel 31 to move out of the lower side of the syringe 61, and driving the second recovery barrel 32 to move to the lower side of the syringe 61; In step 3 , when the needle drop is detected, the controller controls the third driving unit 24 to drive the second recovery bucket 32 ​​to move out of the lower side of the syringe 61 , and drives the third recovery bucket 33 to move to the lower side of the syringe 61 .

[0028] Example 2.

[0029] An application example of the syringe processing device and method in Example 1 of the present invention.

[0030] In this application example, Figure 1 As shown, the syringe 61 includes a needle, a syringe barrel 611 and a piston rod 613 .

[0031] The clamping unit 11 includes a horizontal guide rail 113, a first part 112 and a second part 111, and the first part 112 and the second part 111 are respectively arranged on the horizontal guide rail 113. The adjacent ends of the first part 112 and the second part 111 are arc surfaces matching the syringe 611. Two first drive units 21 (electric telescopic mechanisms) are arranged vertically. 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 is released, and the first part 112 and the second part 111 move away from each other, the syringe 611 falls.

[0032] The cutting unit 23 is an electric scissors.

[0033] The second driving unit 22 is electrically driven, that is, when the first motor rotates, it pushes the sliding member on the vertical guide rail to move up or down. When the sliding member moves down, it pushes the piston rod 612 to move down, and when the first detection unit detects that the rotation resistance of the first motor exceeds the threshold value, it indicates that the end of the piston rod 612 moves to the bottom end in the syringe 611.

[0034] like Figure 2 As shown, the third driving unit 24 includes a second motor and a turntable driven by the motor. The first recovery barrel 31 , the second recovery barrel 32 and the third recovery barrel 33 are evenly arranged on the turntable. When the turntable rotates 120 degrees, the recovery barrels are located at the lower side of the syringe 61 .

[0035] The second detection unit uses image recognition technology to identify whether the needle and the 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.

[0036] The syringe processing method of the embodiment of the present invention, that is, the working method of the syringe processing device, comprises the following steps: Step 1. Place the syringe 61 on the lower side of 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 the first part 112 and the second part 111 downward. 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 can stably clamp the syringe 611.

[0037] Step 2: The second driving unit 22 pushes the piston rod 612 downward, and the piston rod 612 pushes the waste liquid in the syringe 611 to be discharged from the needle and drip into the first recovery barrel 31 arranged at the lower side of the syringe 61.

[0038] When the first detection unit detects that the rotation resistance of the first motor reaches a threshold value, indicating that the end of the piston rod 612 moves to the bottom end of the syringe 611, the first motor stops rotating. The first detection unit sends a first control instruction to the controller.

[0039] The controller controls the third driving unit 24 according to the first control instruction, and the second motor drives the turntable to rotate, thereby driving the first recovery bucket 31 to move out of the lower side of the syringe 61 and driving the second recovery bucket 32 ​​to move to the lower side of the syringe 61.

[0040] Step 3: The controller controls the shearing unit 23 according to the first control instruction, and the shearing unit 23 cuts off the syringe 61, and the needle and the syringe 611 are separated and fall into the second recovery bucket 32 ​​arranged at the lower side of the syringe 61. When the second detection unit detects that the needle has fallen, it sends a second control instruction to the controller.

[0041] The controller controls the third driving unit 24 according to the second control instruction, thereby driving the second recovery bucket 32 ​​to move out from the lower side of the syringe 61 , and driving the third recovery bucket 33 to move to the lower side of the syringe 61 .

[0042] Step 4: The controller controls the first driving unit 21 according to the second control instruction, and the first driving unit 21 releases the first part 112 and the second part 111, and the first part 112 and the second part 111 are separated on the horizontal guide rail 113, thereby releasing the syringe 611, and the syringe 611 and the piston rod 612 fall into the third recovery bucket 33 provided at the lower side of the syringe 61. When the third detection unit detects that the syringe 611 is separated from the clamping unit 11, a third control instruction is issued to the controller.

[0043] The controller controls the third drive unit 24 according to the third control instruction, thereby driving the third recovery bucket 33 to move out from the lower side of the syringe 61, and drives the first recovery bucket 31 to move to the lower side of the syringe 61 to prepare for processing the next syringe 61; the second drive unit 22 retracts upward.

[0044] Example 3.

[0045] According to the application example of the syringe processing device and method in Example 1 of the present invention, the difference from Example 2 is that: The first driving 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 to each other, the syringe is clamped, and when they are far away from each other, the syringe is released.

[0046] Embodiment 2-3 exemplarily shows that the second detection unit and the third detection unit use image recognition technology. Of course, photoelectric detection technology can also be used. Specifically, a laser and a detector are respectively arranged on the left and right sides of the lower side of the needle, and the detector receives the laser signal. When the signal received by the detector is less than the threshold, it indicates that the needle or syringe blocks the passage of the laser, thereby confirming whether the needle or syringe has fallen, and achieving the purpose of automatic and accurate identification.
