The invention discloses an automatic cleaning and glue pouring platform for a capillary array. A push rod is arranged on an electric translation stage; a pressure sensor is arranged on an end surface of the push rod; a microscale sample injector support and a microscale sample injector are arranged on a direction on which the push rod travels; a tail end of the microscale sample injector is clinging to the pressure sensor, and a head of the microscale sample injector is connected with a conduit. A capillary support comprises a capillary head pedestal and a capillary central support, which areseparated, wherein a height of the central support can be adjusted manually. A first path of a transparent tee joint is connected with the head of the microscale sample injector through a conduit; a second path is connected with a head of a capillary; and the third path is connected with a liquid bath liquid bath through a conduit. A pressure sensor display meter is disposed on a platform. The translation stage is equipped with a meter controller with a faceplate, a stepping motor and a direct-current power supply thereon. The platform of the invention can carry out repetitive automatic cleaning and glue pouring on the capillary array, and has advantages of high degree of automation, high cleaning and glue pouring efficiency, compact structure, simple operation and reliable performance, etc.
