The needle tube needle opening sealing mechanism 7 is composed of a clamping block 71, sliding blocks 72, a sliding rail 73 and a sliding block opening and closing air cylinder 74, the sliding rail 73 is fixed on the machine table 1, the two sliding blocks 72 are respectively connected on the sliding rail 73 in a sliding fit mode, a cylinder body of the sliding block opening and closing air cylinder 74 is fixed with one of the sliding blocks 72, the end of a piston rod of the sliding block opening and closing air cylinder 74 is fixed with the other sliding block 72, the two sliding blocks 72 are respectively fixed with the clamping block 71, and the clamping block 71 is made of silica gel.

As shown in figure 1, firstly, the vibrating disk 2 sequentially arranges the needle tubes and conveys the needle tubes forwards, and at this time, the baffle 31 is positioned in front of the outlet of the flow passage of the vibrating disk 2, and the needle tubes cannot move forwards continuously under the block of the baffle 31. Then the piston rod of the horizontal linear driving mechanism 4 drives the needle tube connector sealing detection mechanism 6 to move to the front of the outlet of the flow channel of the vibration disc 2, and the piston rod of the baffle lifting cylinder 32 drives the baffle 31 to move downwards, so that the needle tube can continue to be driven forwards until the needle tube is directly driven to the needle tube connector sealing detection mechanism 6 to be clamped and positioned. Then the needle tube connector sealing detection mechanism 6 detects the smoothness of the needle tube. After the detection is finished, the needle head of the needle tube is clamped and sealed by the needle mouth sealing mechanism 7 of the needle tube, and then the whole needle tube is subjected to leakage detection. After the detection is finished, the needle tube which is detected is clamped and placed in the flow channel 84 of the sorting mechanism 8 by the discharging clamping jaw mechanism 5, the flow channel 84 is driven to rotate by the output shaft of the motor 83, and when the product is qualified, the discharging port of the flow channel 84 is rotated to the upper part of the qualified product hopper 81. When the product is rejected, the outlet of the flow channel 84 is rotated to above the reject hopper 82.

As shown in fig. 2, the needle tube connector sealing detection mechanism 6 works in such a way that when the piston rod of the connecting block opening and closing cylinder 66 extends, the two connecting blocks 65 are driven to move in opposite directions, so that the two clamping plates 64 are opened. The piston rod of the connecting block opening and closing cylinder 66 retracts, so that the two connecting blocks 65 can be driven to move in opposite directions, and the two clamping plates 64 are closed. The clamping plates 64 are each provided with an arcuate slot which merge into a ring when the clamping plates 64 are closed. The spacing between the clamping plates 64 is first controlled so that the needles delivered from the flow channels of the vibratory tray 2 enter between the two clamping plates 64, and then the two clamping plates 64 clamp the needles into the arcuate slots. Then the piston rod of the plug lifting cylinder 62 drives the block body to move downwards, and the plug 61 on the block body moves downwards and plugs the opening of the connector of the needle tube. The spring on the plug 61 can provide buffer for the plug 61, so as to prevent the plug 61 from being in hard contact with the needle tube. After the plug 61 seals the opening of the needle tube connector, gas is blown into the needle tube through the plug 61 in a leakage test, and whether the needle tube is unobstructed or not is judged by observing the air pressure.

As shown in FIG. 3, the needle tube needle mouth sealing mechanism 7 works in such a way that when the piston rod of the slider opening and closing cylinder 74 is extended, the two sliders 72 are driven to move along the slide rails 73 in opposite directions, so that the two clamping blocks 71 are opened. When the piston rod of the slider opening and closing cylinder 74 retracts, the two sliders 72 can be driven to move in opposite directions, so that the two clamping blocks 71 are closed. When the two clamping blocks 71 clamp and seal the needle head of the needle tube, the top end of the needle tube is sealed by the plug 61, then, gas is blown into the needle tube through the plug 61 in a leakage test, and whether the needle tube leaks or not is judged by observing the gas pressure.
