The rubber layer 5 is adhered to the upper part of the side wall of the clamping plate 18 facing the supporting plate 7, the rack 3 is processed at the lower part along the length direction, and the rack 3 is intermittently meshed with the stepping gear 1. The step gear 1 is a step gear driven by a step motor, and the upper part of the step gear is intermittently meshed with the rack 3 on the clamping plate 18. The lower part of the step gear is meshed with the one-way gear 2, and the transmission ratio is 1. The one-way gear 2 comprises a support shaft and a straight gear, and a one-way bearing is connected between the support shaft and the straight gear in an interference fit manner.

The cover taking mechanism comprises a cover taking device, a guide rod 10 and a driving rod 6, wherein the guide rod 10 and the driving rod 6 are arranged side by side and vertically, and the guide rod 10 is a rectangular rod. The drive rod 6 is coaxially welded with the support shaft of the one-way gear 2, the top end of the drive rod 6 is rotatably connected to the frame of the immunoassay analyzer through a bearing, the upper part of the drive rod 6 is provided with a circumferential chute 8, and the high end and the bottom end of the chute 8 are symmetrically distributed on two sides of the rotary axis of the drive rod 6.

The specific implementation process is as follows: as shown in figure 2, when using, the containing blood sample vacuum vessel in the immune analyzer transport mechanism under the removal to the supporting plate 7 department, vacuum vessel in the transport process moves to the positioning roller 15 department, through to immune analyzer transport mechanism form set, for example the conventional adoption step movement or distance movement, make vacuum vessel move to positioning roller 15 department after push positioning roller 15, but can not pass positioning roller 15, make positioning roller 15 keep with the vacuum vessel body 22 upper portion rolling contact, so can keep the body 22 to maintain stable vertical state. Push to positioning roller 15 makes mounting bracket 16 overcome the thrust of spring 14 and move to the outside, makes push rod 4 push ejector pad 21 inwards through the effect of lever 17 is synchronous, makes ejector pad 21 promote rubber layer 5 on the splint 18 and support tightly with the body 22 lower part of vacuum blood collection tube, and the location fixture that the symmetry set up makes splint 18 of layer board 7 both sides move simultaneously and carry out the centre gripping to the lower part of body 22, and the rack 3 symmetry meshing of both sides is in step gear 1's both sides simultaneously. At this time, the cover taking mechanism is in an initial state, and the bearing on the supporting rod 9 is positioned at the high end of the chute 8. The rotation of the step gear 1 is then initiated, a single formation of the step gear 1 preferably being one revolution. The stepping gear 1 rotates to drive the racks 3 on the two sides to move in a staggered manner, so that the clamping plate 18 translates to rub and rotate the pipe body 22, and the positioning roller 15 maintains the stability of the upper part of the pipe body 22 in the rotating process. Because the pushing block 21 slides in the T-shaped groove on the clamping plate 18, the clamping plate 18 does not drive the pushing block 21 to translate during the translation process, and the lever 17 can also limit the translation of the pushing block 21 to a certain extent, so that the tube 22 keeps rotating in place.

In the rotating process, the stepping motor drives the one-way gear 2 to rotate, and the one-way bearing is locked to form a connecting effect to drive the driving shaft to rotate. The driving shaft rotates in-process chute 8 and promotes the branch 9 vertical migration of getting the lid ware, because branch 9 receives the restriction of rectangular guide bar 10 can only vertical translation, and the bearing of branch 9 tip inserts in chute 8, so the rotation of chute 8 acts on the bearing and produces vertical thrust and makes branch 9 vertical migration. The vertical movement of branch 9 divide into two stages, and first stage actuating lever 6 rotates half a circle, and the bearing of branch 9 tip moves the low side from 8 high ends in chute, and branch 9 receives pushing of 8 preceding half sections in chute to move down, drives cutting ferrule 13 and descends in step, and cutting ferrule 13 lower part cover is inserted on vacuum blood collection tube's safety cover 23, and the thrust that moves down orders about safety cover 23 and gets into the throat that snap ring 12 formed, and snap ring 12 receives the extrusion with the safety cover 23 centre gripping. The second stage driving rod 6 rotates half a turn again along the same direction, the bearing at the end part of the supporting rod 9 moves from the low end to the high end of the chute 8, the supporting rod 9 is pushed by the rear half section of the chute 8 to move upwards, the clamping sleeve 13 is driven to ascend synchronously, and the safety cover 23 clamped by the clamping ring 12 in the clamping sleeve 13 ascends synchronously to separate from the pipe body 22. The tube 22 is twisted by the clamping plate 18 in the lifting process, so that the safety cover 23 is lifted to be separated from the tube 22 in the process of separating from the tube 22, and the friction resistance between the butyl rubber plug on the inner side of the safety cover 23 and the surface of the tube 22 can be better overcome, and because the safety cover 23 structure of the conventional vacuum blood collection tube only positions the top end of the tube 22 from top to bottom, the force for separating the safety cover 23 from the tube 22 does not need to be large, and the separation of the safety cover 23 from the tube 22 can be easily realized through the above-mentioned rotating lifting process. The safety cover 23, which is detached from the tubular body 22, remains clamped inside the snap ring 12, and as the drive rod 6 completes one rotation, the bearing at the end of the rod 9 returns to the high end of the chute 8, and the rod 9 returns to the initial state. At the same time, the step gear 1 completes a stroke, and the clamping plate 18 does not rub the tube 22 any more. Then, the stepping gear 1 is controlled to reversely rotate for a stroke, the clamping plate 18 resets, the tube body 22 rotates for a circle in a reverse direction, the one-way bearing freely rotates in the process, the reverse operation of the stepping gear 1 cannot drive the driving rod 6 to rotate through the one-way gear 2, the cap extractor cannot be driven to reversely move, and the phenomenon that the cap extractor is separated from the safety cap 23 and contacts with the tube body 22 again is avoided.

After the safety cap 23 is removed and reset, the transport mechanism of the immunoassay analyzer drives the tube 22 to move through the positioning roller 15, and the next vacuum blood collection tube moves to the positioning roller 15, and the above process is repeated. In the process of continuously taking off the safety cover 23 of the vacuum blood collection tube, the safety cover 23 taken off later pushes the previous safety cover 23 clamped in the clamping ring 12 upwards into the collection hose 11, so that the safety covers 23 are isolated and collected in the collection hose 11 one by one, the collection hose 11 can be connected to an independent collection bag, the automatic collection of the separated safety cover 23 is realized, and the pollution caused by the scattering of the used safety cover 23 at four positions is avoided.

Such device can realize the separation of the safety cover 23 of vacuum test tube automatically to overall structure occupation space is little, can match the immunoassay appearance and use, goes on automatically through mechanical structure, and the action is reliable and stable, effectively avoids the blood sample unrestrained, and the action is efficient, can concentrate by oneself to collect the safety cover 23 of separation, and practical function is showing.

The above description is only an example of the present invention, and the detailed technical solutions and/or characteristics known in the solutions are not described too much here. It should be noted that, for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
