Dispenser and lifting device of dispenser

A dispenser (100) configured to dispense a material on a substrate (110), wherein the dispenser (100) comprises:

• a pair of rails (120) configured to input and output the substrate (110) to the dispenser (100) in an X-axis direction, wherein one of the pair of rails (120) is movable in a Y-axis direction towards or away from the other to adjust a distance between the pair of rails (120), a supporting surface (210) and a blocking portion (220) higher than the supporting surface (210) are disposed on each of the pairs of rails (120), the supporting surface (210) of the pair of rails (120) is configured to support the substrate (110) in a transport position, and the blocking portion (220) of the pair of rails (120) is configured to keep the substrate (110) in a dispensing position;
• a heating device (201) located below the pair of rails (120) in a Z-axis direction and movable in the Z-axis direction;
• and
• a pair of lifting devices (250) mounted to the pair of rails (120) respectively, each of the pair of lifting devices (250) comprising:
• a lifting member (310) movably connected to the rail (120) and movable in the Z-axis direction;
• and
• a reset member (320) located between the rail (120) and the lifting member (310) to be compressed when the lifting member (310) is raised relative to the rail (120) and to be able to lower the lifting member (310) relative to the rail (120) by a resilient force;
• wherein the lifting member (310) is configured to be able to be raised under pushing of the heating device (201) to cause the substrate (110) to rise from the transport position to the dispensing position, and to lower the substrate (110) to the transport position from the dispensing position under an action of the reset member (320) when the heating device (201) descends.
