[0002] A reagent plate is a microreactor with test reagents, used for scientific research and biochemical analysis. The reagent plate is generally made of plastic. After injection molding, the reagent plate needs to be placed on a reagent plate screen printer for printing. The printed text includes number, expiration date, negative and positive identification, etc.

[0003] In common production environments, the following are usually used Figure 5 The visual inspection plate 4 shown is a container for visually inspecting whether the reagent plate has shape defects after the injection molding is completed. It is provided with a plurality of plate positions for placing the reagent plates, and has two end slots 41 and two middle slots 42 for easy manual grasping. The end slots 41 are located at the two ends of the upper end surface of the visual inspection plate 4, and the middle slots 42 are arranged in sequence along the length direction in the middle of the upper end surface of the visual inspection plate 4. In the printing process, as shown in the attached Figure 4 As shown in , the reagent plate screen printer used includes a turntable 31 and four rotating rods thereon, one end of the rotating rod is provided with a placement slot 32 for placing the visual inspection plate 4, the turntable 31 will rotate 90° each time, and the reagent plate on the visual inspection plate 4 on the placement slot 32 on the left side as shown in the accompanying drawing will be screen-printed, and the visual inspection plate 4 on the placement slot 32 on the lower side will be unloaded by the unloading vacuum suction cup of the reagent plate screen printer, and the remaining two placement slots 32 are used to place two new visual inspection plates 4 from the conveyor belt 33. After printing each reagent plate on two visual inspection plates 4, two visual inspection plates 4 need to be placed, however, the reagent plate screen printer does not have its own loading mechanism, so the printing step is not fully automated, and manual loading is required, which consumes a lot of workers' physical strength.

The clamping mechanism 2 includes a horizontal plate 21. Specifically, a larger circular portion 22 is formed on the horizontal plate 21 located at the lower end of the first rotary motor 13 for placing the first rotary motor 13, and a smaller circular portion 22 is formed on the horizontal plate 21 located at the lower end of the output shaft of the second rotary motor 17 for connecting the output shaft of the second rotary motor 17.
