the test strip 5 selected by the strip selecting mechanism 73 is conveyed to the strip pushing device 10, the test strip 5 which originally faces upwards and passes through the sensor 75 and the second sensor 72 to judge the front and back directions is judged for the second time when passing through the third sensor 9 and the fourth sensor 8, is used for further verifying whether the test strip 5 exists, the front side, the back side and the front and back directions, for the test strip 5 which originally faces upwards, the front side and the back direction are not judged after the test strip 5 is turned to face upwards through the strip turning mechanism 74, the front and back direction of the test strip 5 is unknown, therefore, the front and back direction of the test strip 5 is judged when passing through the third sensor 9 and the fourth sensor 8, the judgment method is similar to the method of the sensor 75 and the second sensor 72, namely, if the third sensor 9 and the fourth sensor 8 detect a dark color, no test strip 5 is judged (the test strip pushing device 10 is a dark color, at this time, the third sensor 9 and the fourth sensor 8 detect a dark color, if the third sensor 9 and the fourth sensor detect a dark color, then the test strip 5 detects a dark color, if the third sensor 9 and the fourth sensor detects a light color sensor 9, then the fourth sensor detects a dark color, the test strip 5, then the fourth sensor 365 detects a dark color sensor 35, and the fourth sensor detects a dark color sensor 365, and the fourth sensor detects a dark color sensor, and a light color sensor detects a light color sensor 369 and a fourth.
After the forward and backward directions of the test strip 5 are determined, the test strip 5 conveyed by the strip pushing device 10 is rotated by the test strip rotating device a to the th direction or the second direction of the system , wherein of the th direction and the second direction correspond to the direction of the drop and the test, if the th direction corresponds to the direction of the drop and the test, the test strip with the forward and backward directions being the second direction is reversed, or if the second direction corresponds to the direction of the drop and the test, the test strip with the forward and backward directions being the th direction is reversed.
In this embodiment, the th sensor 75, the second sensor 72, the third sensor 9, and the fourth sensor 8 are all optical sensors or color sensors, wherein the optical sensors determine whether the test strip 5 is present in the test strip slot, the front and back sides of the test strip 5, and the front and back directions of the test strip 5 by detecting the light reflection intensity, and the color sensors determine whether the test strip 5 is present in the test strip slot, the front and back sides of the test strip 5, and the front and back directions of the test strip 5 by detecting color differences.
The whole working process of the dry chemical detection system is as follows:
step 1: placing the test strip 5 into a test strip bin 71;
step 2: the strip selecting mechanism 73 at the bottom of the test paper bin 71 moves back and forth, so that the test paper 5 falls into the test paper slot to complete strip selection;
and step 3: the test paper groove enters a strip judging position;
and 5: when the test strip 5 is right side up, the motor of the strip turning mechanism 74 operates clockwise to keep the test strip 5 right side up; when the test strip 5 is back-side up, the motor of the strip turning mechanism 74 operates counterclockwise to turn the test strip 5 to be front-side up;
step 6: the test strip 5 carries out secondary judgment through a third sensor 9 and a fourth sensor 8, and if no test strip 5 is detected, an alarm signal of no test strip 5 is sent out; if the test strip 5 is detected to be back-side-up, an alarm signal that the test strip 5 is not correctly placed is sent; the third sensor 9 and the fourth sensor 8 also detect the front-back direction of the front surface of the strip 5 if the strip 5 is detected to be right-side-up;
step 7, if the test strip 5 is in the th direction, the test strip 5 is pushed to move to the position of the sample dripping device 12, if the test strip 5 is in the second direction, the strip pushing device 10 is still, and the test strip 5 can be accurately clamped even if the test strip clamp 61 is wider than the test strip 5, because the test strip clamp is wider than the test strip 5, the running error exists, and therefore, the optical coupler is not needed to detect the position of the test strip 5, and certainly, the optical coupler can be arranged to detect the position of the test strip 5;
step 8, after the rotary position is reached, the lifting driving mechanism 2 drives the holder 62 and the test strip clamp 61 to be lifted, the test strip clamp 61 clamps the test strip 5 and lifts the test strip to the rotary position, and after the test strip clamp 61 lifts the test strip 5, the strip pushing device 10 retreats steps, so that the test strip 5 cannot interfere with the strip pushing point when being put down;
and step 9: after the rotation position is stopped stably, the rotation driving mechanism 4 drives the rotating and descending frame 5 to rotate for 180 degrees;
step 10: after the rotation is completed, the lifting driving mechanism 2 with the holder 62 and the test strip clamp 61 descends, the test strip clamp 61 falls into the clamping groove on the edge track of the strip pushing device 10 again, the movable pressing block 614 of the test strip clamp 61 is pushed open, the test strip 5 falls into the strip pushing teeth of the strip pushing device 10 again, and the strip is pushed to the position of the sample dropping device 12;
and 11, carrying out subsequent dropping and detection according to the th direction of the test strip 5.
The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.
Various modifications to these embodiments will be readily apparent to those skilled in the art, and the -like principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
