Be connected with " startup ", " time-out " and " resetting " three operation push-button K1, K2, K3 on the input end of microcontroller respectively, be connected with three indicator lamps and a buzzer phone on the mouth of microcontroller.
Principle of work of the present invention is as follows:
After powering on, enter the state of electrification reset, comprise that the raise one's hat drive motor M1 of frame lifting drive of control just changes, the frame of raising one's hat is moved the 6 moving upper limits that arrive by each parts of the control module control uncapping machine that resets of microcontroller, spacing by four-sensor 804; The drive motor M2 of control Decapping plate actuating device just changes, and Decapping plate 602 is moved to right limit, is in and runs through state, and is spacing or set just commentaries on classics time of the drive motor M2 of Decapping plate actuating device by the 6th sensor 806, is about 0.5S; The drive motor M3 of control test tube box transfer device just changes, and test tube box 4 is shifted out test tube box registration device, is in the front side of frame 1, and is spacing by first sensor 801.
Reset finish after, enter the process of raising one's hat, the drive motor M3 that is controlled test tube box transfer device by the control module of raising one's hat of microcontroller reverses, and test tube box 4 is transplanted on the rear side of frame 1, be in the test tube box locating groove 5, spacing by second sensor 802 and the 5th sensor 805; Control the drive motor M1 counter-rotating of the frame lifting drive of raising one's hat, the frame 6 of raising one's hat is moved to lower limit, spacing by the 3rd sensor 803, at this moment, test tube is in clamped state; The drive motor M2 counter-rotating of control Decapping plate actuating device, Decapping plate 602 is moved to left limit, be in the state of raising one's hat, spacing or set the reversing time of Decapping plate drive motor M2 by the 6th sensor 806, be about 0.5S, the edge in the district 605 of raising one's hat in the hole 603 of raising one's hat this moment enters the below of cap test tube; The drive motor M1 that controls the frame lifting drive of raising one's hat just changes, and the frame 6 of raising one's hat is moved to upper limit, and is spacing by four-sensor 604, and at this moment, cap test tube is broken away from test tube by Decapping plate and is on the circular hole 601 of the frame 6 of raising one's hat; The drive motor M3 of control test tube box transfer device just changes, and test tube box 4 is shifted out test tube box registration device, is transplanted on the front side of frame 1, and is spacing by first sensor 801; The drive motor M2 of control Decapping plate actuating device just changes, Decapping plate is moved to right limit, be in and run through state, at this moment, cap test tube drops on cap test tube and collects in the box 2, collect in the box 2 for the cap test tube on the frame 6 that guarantees to raise one's hat all drops on cap test tube, can control the Decapping plate actuating device again and Decapping plate 602 is moved back into left limit once more moves to right limit then.
Second sensor 802 and the 5th sensor 805 all are provided with two, guarantee that the both sides of the both sides of test tube box pallet 3 and test tube box 4 all arrive the rear side of frame, prevent 3 inclinations of test tube box pallet or test tube box 4 and place the bevelled situations, the action that when the both sides of the both sides of test tube box pallet 3 and test tube box 4 arrive the rear side of frame 1 simultaneously, just begins to enter next step, otherwise out of service and send alarm sound, continue operation again after waiting trouble removal.Do like this and can guarantee the uncapping machine safety; because what adorn in the test tube all is blood of the patient or the person of being verified etc.; might have virus or germ; so must protect test tube in the process safe of raising one's hat, prevent to stave blood in test tube or the test tube and spill and will prevent that test tube from receiving makes excessive vibrations the blood of separator well becomes muddy.
