The device and method for preventing the overflow of glue filling exhaust gas according to claim 1, characterized in that: A base frame (17) is fixedly provided at the bottom of the workbench (1), a second electric push rod (18) is fixedly provided at the top of the base frame (17), an output end of the second electric push rod (18) is fixedly connected to a push rod (19), and the push rod (19) passes through the workbench (1).

7. The anti-overflow device for glue pouring exhaust according to claim 1, characterized in that: Support columns (2) are fixedly provided at the four corners of the bottom of the workbench (1).

8. The anti-overflow device for glue pouring exhaust according to claim 1, characterized in that: One side of one of the baffles (30) is provided with an observation window (33).

9. A method for preventing the exhaust of glue pouring from overflowing, based on a device for preventing the exhaust of glue pouring from overflowing as claimed in any one of claims 1 to 8, characterized in that: The specific steps are as follows: S1. Pass the two arc blocks (42) of the fixing component through the through hole of the PCB board, then turn the knob (40), the knob (40) drives the threaded rod (39) to rotate, the threaded rod (39) drives the two threaded blocks (41) to move to both sides, the threaded block (41) drives the arc block (42) to move, so that the two arc blocks (42) are against the side of the through hole, thereby fixing the PCB board, then adsorb the magnet (36) on the bottom of the magnet plate (5), start the first electric push rod (4), the first electric push rod (4) controls the magnet plate (5) to move downward, the magnet plate (5) drives the fixing component and the PCB board to move downward, thereby controlling the descending depth of the PCB board according to the required thickness of the glue injection; S2, start the first motor (7), the first motor (7) controls the first screw rod (8) to rotate, the first screw rod (8) drives the two first sliding plates (10) to move, the two first sliding plates (10) respectively drive the first connecting plate (11) and the first special-shaped connecting plate (12) to move, the first connecting plate (11) and the first special-shaped connecting plate (12) drive the fixing rod (20) to move, the fixing rod (20) drives the side slider (21) to move, the side slider (21) pushes the two baffles (30) on both sides thereof to move closer to each other and clamp the PCB board, the rubber The pad (34) and the rubber side pad (35) enhance the sealing of the connection and prevent glue leakage, so that there is no gap at the contact position, the second motor (25) is started, the second motor (25) controls the second screw rod (29) to rotate, the second screw rod (29) drives the two second sliding plates (24) to move, the two second sliding plates (24) respectively drive the second connecting plate (26) and the second special-shaped connecting plate (27) to move, the second connecting plate (26) and the second special-shaped connecting plate (27) drive the fixing rod (20) to move, the fixing rod (20) drives the side slider (21) to move, the side slider (21) pushes the two baffles (30) to move, clamps the PCB board from the other two sides, and there is no gap at the contact position; S3, connect the glue tank through the input pipe (14), and inject the glue through the output pipe (16) to the top of the workbench (1) through the pump (15). The glue rises slowly upward and discharges the air from the through hole of the PCB board until the glue contacts the PCB board. After the glue is solidified, start the second electric push rod (18), the second electric push rod (18) controls the push rod (19) to move upward, and the push rod (19) pushes the PCB board out to facilitate unloading.
