Sample Rack Loading System and Loading Method, and Chemiluminescence Detector

A sample rack loading method, used for transferring sample racks from a sample rack storage device to a sample rack transmission device via a sample rack transfer device, wherein the sample rack storage device is provided with a plurality of sample holders for storing the sample racks;

• each of the sample holders is provided with a delivery port through which each of the sample racks is moved out or moved into;
• the sample rack transmission device comprises a rail component and a sample rack block piece mechanism for blocking a transmission passage of the rail component;
• the sample rack block piece mechanism comprises a block piece and an elastic element;
• the elastic element drives the block piece to block the transmission passage;
• the sample rack transfer device comprises a transfer rail and a sample rack driving mechanism;
• the transfer rail can be in abutment joint with the delivery port and/or the transmission passage;
• and the sample rack loading method comprises the following steps:
• (a) moving the sample rack transfer device to one end of the transmission passage of the rail component, so that the transfer rail of the sample rack transfer device is in abutment joint with the transmission passage;
• and
• (b) transferring, by the sample rack driving mechanism, the sample racks from the transfer rail to the transmission passage;
• and
• in the step (a), the sample rack transfer device is pressed against the block piece that blocks on the transmission passage, so that the block piece unblock the transmission passage.
