More Information
Summary:Disclosed are a positioning method, a positioning apparatus and a sequencing system (300). The sequencing system (300) comprises an imaging assembly (110) and a mobile platform (102), wherein the imaging assembly (110) comprises an optical axis (OP), the mobile platform (102) bears a reaction apparatus (200), the stroke of the mobile platform (102) in a first direction is controlled by means of a limiting switch, and the stroke comprises a first limit. The method comprises the steps: (a) moving, by a first step distance, the mobile platform (102) in a direction approaching the first limit, until the distance between a current position of the reaction apparatus (200) and the previous position of the reaction apparatus (200) is less than the first step distance; (b) moving the mobile platform (102) in a direction that is the opposite of the moving direction in step (a); (c) moving the mobile platform (102) in the moving direction in step (a), until the mobile platform (102) reaches the first limit; and (d) moving, by a preset distance, the mobile platform (102) in the direction that is the opposite of the moving direction in step (a), so that the positions of the optical axis (OP) and the reaction apparatus (200) satisfy a preset relationship. According to the method, the quick and precise positioning of the mobile platform (102) can be realized by means of moving back and forth in the first direction, such that the positions of the optical axis (OP) and the reaction apparatus (200) satisfy a preset relationship.
