一种具有自动开关门机构及吊篮调整机构的组件的血液离心机A blood centrifuge with components of an automatic door opening mechanism and a hanging basket adjustment mechanism

技术领域technical field

本发明涉及一种离心分离设备，具体涉及一种具有自动开关门机构及吊篮调整机构的组件的血液离心机。The invention relates to a centrifugal separation device, in particular to a blood centrifuge with components of an automatic door opening mechanism and a hanging basket adjustment mechanism.

技术背景technical background

血液成份的分离一般在血液离心机中进行，目前国内血液离心机多为手工抓取血型卡，这样就需要采用手动翻盖式开门机构，同时由于采用手动抓取方式，就不需要对吊篮的角度进行严格要求，所以在吊篮静态时就可手动取卡。但全自动血型分析仪的使用的离心机要求为无人工全自动操作系统，就不能使用手动翻盖式开门机构，同时抓取血型卡均为机械手进行，所以对吊篮倾斜角度进行要求。所以目前市场上现有的离心机不能满足全自动开门及对吊篮角度调整的要求。The separation of blood components is generally carried out in a blood centrifuge. At present, most blood centrifuges in China use manual capture of the blood type card, which requires a manual flip-type door opening mechanism. The angle is strictly required, so the card can be manually removed when the hanging basket is static. However, the centrifuge used by the automatic blood type analyzer is required to be a fully automatic operating system without manual operation, so the manual flip-type door opening mechanism cannot be used. At the same time, the blood type card is captured by the robot, so the tilt angle of the hanging basket is required. Therefore, the existing centrifuges on the market cannot meet the requirements of fully automatic door opening and angle adjustment of the hanging basket.

本发明的具有自动开关门机构及吊篮调整机构的组件的血液离心机工作时包括如下工作步骤，首先实现全自动开关门：向步进电机25通电，步进电机25通过销23带动小齿轮22转动，小齿轮22与大齿轮21形成齿轮啮合传动，大齿轮21在隔套34和锁紧螺母36的挤压下保持水平状态，可以保证齿轮顺利啮合不卡涩，固定轴承座31固定在上盖11中心的下方，与轴承32外圈及压板35一同起固定作用，轴承32内圈、隔套34、旋转轴承座33、锁紧螺母36一同随大齿轮21旋转，当光耦挡片12在随大齿轮21旋转过程中，处于遮挡第一光耦26的时候，此时电机25停止工作，使大齿轮21上的预留孔洞与上盖11的预留孔洞完全重合，此时处于自动门的打开状态，可以进行抓取血型卡工作；当抓取血型卡完毕后，启动步进电机25，使小齿轮22继续旋转，通过对步进电机25进行查步，从而控制大齿轮21的旋转角度，当上盖11的预留孔洞完全将大齿轮21上的预留孔洞覆盖后，使步进电机25断电，实现自动开门的关闭状态。The blood centrifuge with the assembly of automatic door opening mechanism and hanging basket adjustment mechanism of the present invention includes the following working steps when it works. First, it realizes automatic door opening and closing: energize thestepping motor 25, and the steppingmotor 25 drives the pinion through thepin 23 22 rotates, thepinion gear 22 and thebull gear 21 form a gear meshing transmission, and thebull gear 21 maintains a horizontal state under the extrusion of thespacer 34 and thelock nut 36, which can ensure the smooth meshing of the gears without jamming, and the fixed bearingseat 31 is fixed on The lower part of the center of theupper cover 11 is fixed together with the outer ring of thebearing 32 and thepressure plate 35. The inner ring of thebearing 32, thespacer 34, the rotating bearingseat 33 and thelock nut 36 rotate together with thelarge gear 21. 12 In the process of rotating with thelarge gear 21, when thefirst optocoupler 26 is blocked, themotor 25 stops working at this time, so that the reserved holes on thelarge gear 21 and the reserved holes of theupper cover 11 are completely overlapped. When the automatic door is opened, the blood type card can be captured; when the blood type card is captured, thestepper motor 25 is started to continue the rotation of thepinion gear 22, and thestepper motor 25 is checked to control thelarge gear 21 When the reserved hole on thebull gear 21 is completely covered by the reserved hole of theloam cake 11, thestepper motor 25 is powered off to realize the closed state of automatic door opening.

接着进行吊篮调整机构工作过程：在离心机停止工作后，吊篮51处于静止倾斜状态，电机56固定在底板60底面，此时对电机56通电，调整丝杠53通过圆柱销55与电机56旋转轴连接一同旋转，通过螺纹传动，带动调整螺母52运动，调整螺母52与导轨54相配合，沿着导轨54面向上运动，在调整螺母52向上运动过程中，与吊篮51底部相接触，使吊篮52绕其轴转动，当光耦挡片59挡住第二光耦57时，电机56停止工作，调整螺母52停止向上运动，此时吊篮51恰好处于水平位置，此时达到机械手抓取卡的角度位置要求；当机械手抓取卡完毕后，对电机56进行反向通电，使调整螺母52向下运动，当光耦挡片59挡住第三光耦58时，电机52停止通电，此时调整螺母52处于最底端，然后旋转离心盘，进行下一吊篮的调整工作。周而复始，使所有吊篮全部调整后进行血型卡的抓取工作。Then carry out the working process of the hanging basket adjustment mechanism: after the centrifuge stops working, the hangingbasket 51 is in a static tilting state, and themotor 56 is fixed on the bottom surface of the base plate 60. At this time, themotor 56 is energized, and the adjustment screw 53 passes through the cylindrical pin 55 and themotor 56 The rotating shafts are connected to rotate together, and through screw transmission, the adjustment nut 52 is driven to move. The adjustment nut 52 cooperates with theguide rail 54 and moves upward along theguide rail 54. During the upward movement of the adjustment nut 52, it contacts with the bottom of the hanging basket 51. Make the hanging basket 52 rotate around its axis, when the optocoupler block 59 blocks the second optocoupler 57, themotor 56 stops working, the adjustment nut 52 stops moving upwards, and at this moment, the hangingbasket 51 is just in the horizontal position, reaching the manipulator to grasp The angle position requirement of taking the card; after the manipulator grabs the card, themotor 56 is reversely energized to make the adjustment nut 52 move downward. Now the adjustment nut 52 is at the bottom end, and then the centrifugal disc is rotated to carry out the adjustment work of the next hanging basket. Go round and round, after all the hanging baskets are adjusted, the grabbing work of the blood type card will be carried out.
