It is to be understood that the height direction, width direction, and length direction described in the present embodiment refer to the height direction, width direction, and length direction shown in fig. 2.
In the full-automatic sample application production line of the embodiment, eleven sample application mechanisms are sequentially arranged on the workbench 1 at intervals along the conveying paths of the first conveying components 2, after the test paper 3 to be applied is placed between the feeding ends of the two first conveying components 2, when the two first conveying components 2 convey the test paper 3 to be applied to the position right above the sample application platform 41, the lifting component is controlled to start lifting the sample application platform 41, the sample application platform 41 lifts the test paper 3 to be applied to be separated from the upper surface of the first conveying components 2 so that the sample application needle component applies the reagent to the square of the test paper 3, then the lifting component is controlled to start lifting the sample application platform 41 to descend so as to replace the test paper 3 on the upper surface of the first conveying components 2, and the test paper 3 is automatically conveyed to the next mechanism to perform sample application work of the corresponding square, so that automatic sample application of the test paper 3 is realized; meanwhile, because the sample application mechanisms at different positions are respectively used for applying different reagents to the corresponding rows of the square boxes on the test paper 3, the test paper 3 sequentially passes through the process under the sample application needle assemblies at different positions under the conveying of the two first conveying assemblies 2, so that different reagents are respectively applied to the corresponding rows of the square boxes on the test paper 3 through the independent sample application mechanisms, the process that the two first conveying assemblies 2 convey the test paper 3 from the feeding end to the discharging end of the test paper 3 can be realized, the sample application work of respectively applying different reagents to the corresponding rows of the square boxes of the test paper 3 can be completed at one time, the sample application efficiency is high, cross infection among different reagents can be effectively avoided in the whole sample application process, and the probability of producing defective products is reduced. The visual detection parts 42 are arranged on the two-axis moving assemblies of each sample application mechanism, when the test paper 3 to be sampled passes through the position right above one of the sample application tables 41 under the conveying of the two first conveying assemblies 2, the lifting assemblies at the corresponding positions are controlled to start lifting the corresponding sample application table 41, the sample application table 41 supports the test paper 3 to be sampled and is separated from the upper surface of the first conveying assembly 2, then the visual detection parts 42 at the corresponding positions are driven by the two-axis moving assemblies to respectively shoot a pair of opposite angles of the test paper 3 to obtain a first image, the first image is transmitted to the controller, the controller compares the first image obtained by shooting with the first standard image, and judges whether the test paper 3 supported by the sample application table 41 is offset or not, if so, the test paper 3 is placed to be offset according to the offset value acquired by comparing the first image with the first standard image, and the two-axis moving assemblies at the corresponding positions are controlled to move according to the corrected moving track of the corrected sample application needle assemblies at the corresponding positions, then the corresponding positions of the sample application needle assemblies at the corresponding positions are controlled to move along the moving track corrected according to the offset value of the actually-produced test paper 3, the sample application needle 3 is accurately placed along the sample application needle 3, and the sample application needle is not accurately placed in the corresponding sample application test paper 3 is not accurately placed according to the moving track of the sample application test paper is automatically controlled, and the sample application reagent is not accurately placed along the sample application test paper is not accurately placed according to the corresponding to the moving track of the test paper. And the first image is obtained by shooting a pair of opposite angles of the test paper 3, so that the first image can be more accurately compared with the first standard image, and the offset value can be more accurately obtained.
When the test paper 3 lifted by the spotting table 41 is not shifted, the shift value is zero, that is, the movement trace does not need to be corrected.
Specifically, the first standard image is an image obtained by photographing the test paper 3 on the spot sample table 41, which is not shifted.
Specifically, the first image includes two images obtained by photographing a pair of diagonal corners of the test paper 3 on the sample stage 41, respectively.
Specifically, the visual detection section 42 is provided as a CCD camera.
Note that, the test paper 3 in which no offset is generated means that the length direction of the test paper 3 is parallel to the length direction, and the width direction of the test paper 3 is parallel to the width direction; the test paper 3 generating the offset refers to the test paper 3 generating a certain angle of rotation around the height direction relative to the test paper not generating the offset, namely, the length direction and the length direction of the test paper 3 generating the offset form a non-zero included angle, and the width direction of the test paper 3 generating the offset form a non-zero included angle; the offset value is an offset angle of the offset test paper 3 relative to the test paper 3 which does not generate offset and rotates around the height direction, that is, one square in the same row of square of the test paper 3 which does not generate offset is only required to move along the length direction (original moving track) to an adjacent square, and one square in the same row of square of the test paper 3 which generates offset is required to move along the length direction by a certain displacement amount and also required to move along the width direction by a certain displacement amount (corrected moving track); the controller corrects the movement trajectory according to the offset value based on the above-described principle.
In a specific application, the number of the spotting mechanisms may be increased or decreased reasonably according to the number of the reagents to be spotted on the test paper 3, for example, in other embodiments, the spotting mechanisms may be two, three, four, five, etc. other numbers.
