Background
In the existing automatic medical appliance assembling device with needle tube puncture type, a transfer jig is firstly placed in a transmission mechanism, and the transfer jig is moved to different stations through the transmission mechanism. First, the transferring jig moves to the needle seat fixing device, and the needle seat fixing device fixes a plurality of needle seats on the transferring jig, wherein needle tube inserting openings on the needle seats face upwards. Then the transmission mechanism moves the jig to the needle tube mounting device, and the needle tube mounting device enables the needle tube to vertically fall into the needle tube inserting opening on the needle seat. However, when the plurality of needle holders are fixed on the transfer jig by the needle holder fixing device, part of the needle holders cannot be correctly dropped on the transfer jig and scattered aside, and the transfer jig which is moved out of the station of the needle holder fixing device enters the station of the needle tube mounting device again, and although part of the needle holders are missing, the needle tube mounting device adopts a mode of uniformly dropping all the needle tubes in the rows, so that the needle tubes at the station which is missing the needle holders are dropped. The needle tube which is not received by the needle seat can scatter around the needle tube mounting device, and as one end of the needle tube is very sharp, the maximum diameter of the needle tube is very small, the needle tube can easily enter gaps among different parts of equipment, so that the equipment is in fault, and equipment maintenance personnel are easy to be stabbed due to the fact that the needle tube is not clearly seen when the equipment maintenance personnel maintain the equipment, so that high potential safety hazards exist.

However, because the scraper blade only moves horizontally in above-mentioned file, in order to guarantee that the scraper blade can get the faller relatively and remove, must keep certain clearance between the two, and needle tubing cross-section size is less, when stirring the needle tubing, some needle tubing is blocked easily, the distance of stirring is not enough to appear the needle tubing can not fall into the downthehole condition of slide smoothly, leads to the needle file to not normally adorn the needle, further increases the rejection rate.
