Patent ID: 7591517

Claim:
A micro-droplet injection apparatus, comprising: an injection module, including an injection head with a plurality of jet orifices, for injecting a micro-droplet on a substrate, and an attitude adjusting module, for adjusting a parallelism and a distance between the injection head and the substrate; a moving stage module, for carrying the substrate, such that the substrate moves relative to the injection head, wherein the moving stage module has an X-Y axis moving device for controlling the movement of the substrate, and a rotating module on the X-Y axis moving device for controlling the rotation of the substrate; an image detection module, for detecting a relative position between the injection module and the substrate and the injection state of the injection module; and a temperature controlling module, disposed on the moving stage module, for controlling the substrate surface temperature, the temperature controlling module including: a plate layer: a cooling layer, with one side contacting the plate layer; a heat insulation layer, with one side contacting the other side of the cooling layer; a temperature controlling layer, with a heating element for heating the temperature controlling layer, wherein one side of the temperature controlling layer is in contact with the other side of the heat insulation layer; a clamping layer, contacted with the other side of the temperature controlling layer, for clamping the substrate; a cooling module, selectively connected with the temperature controlling layer and the cooling layer; and a cooling switcher, for switching the cooling module connected with the cooling layer, such that the moving stage module is in a heating state, or switching the cooling module connected with the temperature controlling layer, such that the moving stage module is in a cooling state.
