By adjusting the position of the positioning seat 306, adjusting the moving distance of the contact frame 304, and adjusting the moving distance of the piston 302b, the hot melt adhesive inside the glue cylinder 201 is extruded quantitatively, thereby achieving the purpose of quantitative glue supply. Moreover, the hot melt adhesive inside the glue cylinder 201 can be discharged in stages, so that the glue cylinder 201 is pre-stored with hot melt adhesive, reducing the number of times the glue cylinder 201 needs to be replaced.

[0039] Specifically, a crossbeam 301 is positioned above the substrate 1, and a connecting frame 301a is connected to the end of the crossbeam 301.

The stabilizing plate 303a is connected to the side wall of the mounting frame 303b.

[0041] The operation process of this embodiment is as follows: The operator loosens the screw 306a clockwise, pushes the positioning seat 306, and the positioning seat 306 moves along the crossbeam 301. The operator judges the distance the positioning seat 306 has moved by the scale value indicated by the scale 305, determines the distance the contact frame 304 has moved, and determines the distance the piston 302b has moved, so as to achieve quantitative glue dispensing. After the positioning seat 306 is moved to the working position, the screw 306a is tightened counterclockwise to lock the position of the positioning seat 306. The hydraulic cylinder 302 is activated, the hydraulic rod 302a extends, and the piston 302b squeezes the hot melt glue inside the glue cylinder 201. The hot melt glue inside the glue cylinder 201 is discharged through the glue outlet 205a. At the same time, the contact frame 304 moves toward the positioning seat 306. When the contact frame 304 contacts the positioning seat 306, the hydraulic cylinder 302 closes and the piston 302b stops moving.
