[0002] The plate washer is a device used in the plate washing step in the enzyme-linked immunosorbent assay kit. Its main function is to use washing buffer to wash the residual substances such as substrates, antigens or antibodies in the kit to ensure the accuracy and reliability of subsequent detection steps, reduce errors in manual operations, and ensure the accuracy of experimental results. At the same time, the plate washer can also save the time and energy of the experimenter and improve the efficiency of the experiment. The existing plate washing mechanism usually only washes one side of the reagent plate, which is not thorough enough. In addition, the existing plate washing mechanism usually does not have a post-cleaning process, and the reagent plate can only be dried by itself. It is inevitable that there will be residual cleaning liquid, resulting in inaccurate detection. Summary of the invention

[0003] In order to solve the above problems, the utility model provides a plate washing mechanism for an enzyme-linked immunosorbent assay kit, in which a transmission cleaning mechanism cleans both sides of a reagent plate in a clamping mechanism at the same time, so that the cleaning is more thorough. After the cleaning is completed, a drying mechanism wipes the reagent plate to avoid residual cleaning liquid affecting the accuracy of subsequent detection.

The long rack 103 on the long strip plate 102 is meshed with the single rack turntable 705. When the single rack turntable 705 rotates, the long strip plate 102 is moved laterally through the long rack 103. When the short rack 104 moves to the second gear plate 803, it meshes with it, driving the second gear plate 803 to rotate, so that the reagent plate clamped by the sliding plate 804 in the L-shaped rotating rod 802 reaches the drying mechanism 9.

[0044] Furthermore, a ratchet disk 10 is rotatably provided on the front side of the inner wall of the cleaning box 1 close to the transmission cleaning mechanism 7, a ratchet rod 11 is rotatably provided between the ratchet disk 10 and the transmission cleaning mechanism 7, a damping telescopic rod 12 is fixedly provided on the rear side of the ratchet rod 11, and when the second gear disk 803 rotates, the damping telescopic rod 12 on the rear side of the ratchet rod 11 is pushed in the opposite direction through the convex rod 807, and the damping of the damping telescopic rod 12 slows down the descending speed of the ratchet rod 11.

[0045] By adopting the above structure, the reagent plate to be cleaned is placed between the sliding plates 804 of the clamping mechanism 8 at the lifting door 3, and the transmission cleaning mechanism 7 is started. The brush 702 between the first rotating shaft 701 and the second rotating shaft 704 cleans both sides of the reagent plate.

When the broken rack in the long plate 102 and the second gear disk 803 in the clamping mechanism 8 are engaged, the L-shaped rotating rod 802 is rotated one hundred and eighty degrees to reach the drying mechanism 9. At this time, the power mechanism 6 is started, and the first gear disk 602 in the power mechanism 6 provides power for the two gear turntables 902. The reagent plate is wiped by the wiping cloth 903 on the gear turntable 902, so that the reagent plate is quickly dried.
