Embodiment 1

[0032] Such as Figure 1-Figure 4 As shown, a manipulator for an automatic blood type detector includes a support 1, a drive motor 2 installed on the support 1, a first sensor 3, a second sensor 4, two linear guide rail assemblies 5, and the drive motor 2 vertically supports The seat 1 is set, the drive motor 2 is fixed with a crank wheel 6, and the two linear guide rail assemblies 5 are respectively connected with the crank wheel 6 through the connecting rod 7, and each linear guide rail assembly 5 is fixed with a clamping piece 8, and the two clamping A tension spring 9 is connected between the parts 8, and the tension spring 9 is arranged parallel to the linear guide rail assembly 5.

[0033] The preferred linear guide rail assembly 5 of the present invention includes a guide rail 10, a slider 11 sliding along the guide rail 10, and a connecting plate 12 fixed to the slider 11. The guide rail 10 is fixed on the support 1, and a positioning pin 13 is fixed on the connecting ...

Embodiment 2

[0041]Such as Figure 5-Figure 8 As shown, the difference between the second embodiment and the first embodiment is that the peripheral surface of the crank wheel 6 is provided with a boss 21, when the clamping head 17 moves to the closed state, that is, when the clamping head 17 clamps the blood card 20, the boss 21 The position of 21 is the first rotation position; when the clamping head 17 moves to the open state, that is, when the clamping head 17 releases the blood card 20, the position of the boss 21 is the second rotation position. One end of the first sensor 3 and one end of the second sensor 4 both vertically extend out of the support 1 , the first sensor 3 is set corresponding to the first rotation position, and the second sensor 4 is set corresponding to the second rotation position.

[0042] The working principle of this embodiment is as follows:

[0043] When the driving motor 2 rotates in the forward direction, the crank wheel 6 connected to the driving motor 2 ...

Abstract

The invention relates to a mechanical arm for an automatic blood type detector. The mechanical arm comprises a support, a drive motor, a first sensor, a second sensor and two linear guide rail assemblies, wherein the drive motor, the first sensor, the second sensor and the two linear guide rail assemblies are mounted on the support. A crank wheel is fixed on the drive motor. The two linear guide rail assemblies are connected with the crank wheel through connecting rods respectively. A clamping piece is fixed on each linear guide rail assembly. A tension spring is connected between the two clamping pieces. The mechanical arm for the automatic blood type detector has the advantages that a crank, the connecting rods, the linear guide rail assemblies and the tension spring are matched so that the elastic force of the tension spring can be adjusted to guarantee that the clamping force on a blood card is constant, and the defect that the clamping force is insufficient or overmuch due to the fact that the motor directly drives the clamping pieces is overcome; when fingers are in an opened or closed state, the elastic force of the tension spring and mechanical limiting are used for maintaining the state, and the motor is in a non-operating state at the same time, so that the energy-saving effect is good; the control mode is simple because the motor only needs to be driven to rotate forwardly or reversely; the mechanical structure is simple, and cost can be effectively lowered.

Description

technical field [0001] The invention relates to a medical device, in particular to a manipulator for an automatic blood type detector. Background technique [0002] Immuno-column gel detection method is currently the most advanced detection method in the field of serology. It applies the principle of molecular exclusion chromatography to blood group serology detection, and solves the problems of mixed blood sample detection standards. Compared with traditional glass The chip method and test tube method have the advantages of high sensitivity, easy standardization, and long-term storage of reagent cards at room temperature. For the blood group automatic detection instrument used in the immune microcolumn gel detection method, it needs to solve a series of functions such as sample addition, warm bath, blood card handling, marking and puncturing, and test result discrimination. The system stability of blood type automatic detection instrument is particularly important. [000...
