Finally, the needle mounting mold 100 is clamped to the washing station 430, and the multiple brushes 470 of the washing unit wash the multiple needles 300 on the needle mounting mold 100. Among them, the main function of enzyme liquid soaking is to remove organic pollutants on the needles 300, such as blood, protein, lipids, etc.

[0051] The clamping and moving mechanism 200 clamps the needle installation mold 100 located on the feeding station 480 to the first cleaning tank 400 for rinsing and to the second cleaning tank 410 for enzyme liquid immersion in sequence, and then clamps the needle installation mold 100 soaked in enzyme liquid to the washing station 430, and the first driving member 440 drives the transmission member to move, thereby driving the brush 470 to wash the needle 300 on the needle installation mold 100.

[0055] When the first driving member 440 and the second driving member 530 work simultaneously, they can drive the brush 470 to perform linear motion along a direction perpendicular to the discharge platform 510, and perform rotational motion while performing linear motion, thereby achieving that multiple brushes 470 can scrub multiple needles 300 located on the scrubbing station 430 through linear reciprocating motion and multiple brushes 470 can scrub multiple needles 300 located on the scrubbing station 430 through rotational motion. The combination of the two scrubbing methods can effectively improve the cleanliness of scrubbing.

[0076] This embodiment discloses a needle cleaning method, which is characterized by using the needle cleaning device in embodiment 1 or embodiment 2, and the method is as follows:

[0077] Fixing a plurality of needles 300 on the needle mounting mold 100 and keeping the tips of the needles 300 facing upward;

[0078] The clamping and moving mechanism 200 grabs the needle installation mold 100 and puts it into the first cleaning tank 400 for 5 minutes of pure water washing;

[0079] The clamping moving mechanism 200 then grabs the needle installation mold 100 and puts it into the second cleaning tank 410 for 15 minutes of immersion and ultrasonic treatment;

[0080] The clamping moving mechanism 200 then grabs the needle installation mold 100 and reaches the washing station 430, and the washing unit washes and decontaminates the needle 300;

[0081] The clamping and moving mechanism 200 grabs the needle installation mold 100 and enters the second cleaning tank 410 again for immersion and ultrasonic treatment;

[0082] The clamping and moving mechanism 200 grabs the needle installation mold 100 and enters the first cleaning tank 400 again for pure water washing.

[0083] Specifically, the plurality of needles 300 are fixedly mounted on the plurality of mounting holes 660 of the needle mounting mold 100, arranged in a rectangular shape in a plurality of rows and columns, and the tips of the needles 300 are kept facing upwards;

[0084] The clamping moving mechanism 200 is started, and the mechanical arm 210 rotates or linearly moves in the horizontal plane to drive the needle mounting mold 100 to move in the horizontal plane, and the linear drive unit 220 moves up and down to drive the needle mounting mold 100 to move in the height direction; the mechanical arm 210 drives the needle mounting mold 100 to the top of the first cleaning tank 400, and the linear drive unit 220 moves downward, so as to put the needle mounting mold 100 into the first cleaning tank 400, and then start to wash the needle mounting mold 100;

[0085] The linear drive unit 220 moves upward to lift the needle mounting mold 100 to the outside of the first cleaning tank 400, the robot arm 210 drives the needle mounting mold 100 to move above the second cleaning tank 410, and the linear drive unit 220 moves downward to place the needle mounting mold 100 into the second cleaning tank 410, and then the needle mounting mold 100 is immersed in the enzyme solution and ultrasonically cleaned;

[0086] The linear drive unit 220 moves upward to lift the needle mounting mold 100 to the outside of the second cleaning tank 410, and the robot arm 210 drives the needle mounting mold 100 to move above the washing station 430, and the linear drive unit 220 moves downward to place the needle mounting mold 100 on the washing station 430;

[0087] Then, the first driving member 440 is started, driving the plurality of brushes 470 arranged in a straight line to perform linear motion, thereby linearly cleaning the plurality of needles installed on the needle mounting mold 100; at the same time, the second driving member 530 is started, driving the plurality of brushes 470 to perform rotational motion, thereby rotationally cleaning the plurality of needles installed on the needle mounting mold 100;

[0088] After the washing at the washing station 430 is finished, the robot arm 210 and the linear drive unit 220 grab the needle mounting mold 100 again and put it into the second washing tank 410 for immersion and ultrasonic treatment to separate the stains brushed off by the brush 470 from the needle;

[0089] After the second enzyme solution soaking, the robot arm 210 and the linear drive unit 220 grab the needle mounting mold 100 to the first cleaning tank 400 for another rinsing process;

[0090] Preferably, after the second enzyme solution immersion, the robotic arm 210 and the linear drive unit 220 can grab the needle mounting mold 100 to the third cleaning tank 400 for another flushing treatment; since the third cleaning tank 420 is located between the second cleaning tank 410 and the discharge platform 510, performing a second flushing in the third cleaning tank 420 is beneficial to reducing the stroke of the robotic arm 210 and improving work efficiency.

[0091] The cleaned needle mounting mold 100 is placed in a drying box 910 for drying, and the LED light 920 is turned on for disinfection.

[0092] The needle cleaning method in this embodiment can efficiently clean the needle through multiple cleaning processes such as water washing, enzyme solution soaking, and washing by a washing unit, and can clean multiple needles at the same time. It has a high degree of automation and efficiency, and can ensure the consistency of the cleaning standards of multiple needles, so that multiple needles can meet the hygiene standards after cleaning. In addition, the bottom of the second cleaning tank 410 is provided with an ultrasonic cleaning device, which can more efficiently remove stubborn stains on the needles, thereby achieving a higher cleaning standard.
