[0002] PCR stands for polymerase chain reaction. The samples loaded on the PCR plate are subjected to continuous heating and cooling. In PCR experiments, sample loading and reagent addition are required. PCR plates usually need to be placed on a discharge block for modular transportation.

[0003] A Chinese patent with publication number CN113999753A discloses a PCR plate, which includes reaction tubes and a panel made of PC material. The reaction tubes are arranged below and connected to the panel, and the panel is provided with through holes corresponding to the reaction tubes. The PC material has a high tolerance to the constantly changing heating and cooling thermal cycle process, which prevents the panel from deforming due to temperature and will not stick to the PCR heating module, thereby improving work efficiency. In addition, the PC material has higher structural strength, and the robot arm will not cause deformation of the panel when clamping the PCR plate, which can be well adapted to the automation system.

[0004] Although the above technology solves the problem of the PCR plate sticking to the PCR heating module and being difficult to remove, when the PCR plate is placed, due to the different sizes of the PCR plates, the fixed position is fixed, and PCR plates of different sizes cannot be fixed exactly. Under the action of external force, the PCR plate is easily offset, resulting in poor cleaning, printing and curing effects.

[0005] Therefore, a modular PCR plate discharging block is proposed to address the above problems. Utility Model Content
