Abstract
The utility model discloses a photomask box bonding glue injection device which comprises an injection pipe, a plate body and a shell, an electric control plate is arranged in the shell, a servo motor is arranged on the inner wall of the shell, the output end of the servo motor is connected with a lead screw, the lead screw is in threaded connection with a rod body, the end of the rod body is connected with a piston, and the piston is in sealed sliding connection with the injection pipe. The output end of the injection tube is in threaded connection with a needle, and a guide strip is arranged on the rod body. The servo motor is electrically connected to drive the lead screw to rotate, the lead screw is in threaded connection with the rod body, under the limitation of the guide strip and the guide opening, the piston is driven to move back, glue is sucked into the injection pipe, the servo motor rotates reversely, the piston is driven to move forwards, the glue is extruded out of the needle head, and after the piston is extruded to the bottom, the elastic piece is compressed. The device plays a role in protection, prevents the piston and the injection tube from being excessively extruded to cause breakage of the injection tube, improves safety, can be operated by a single hand, and is convenient for glue injection and plate sticking.
