In this embodiment, the glue outlet member 16 is a duckbill valve, and the caliber of the duckbill valve is smaller than the minimum caliber of the membrane tube 144, so that the duckbill valve can continuously discharge hot-pressed glue, and the glue outlet is not interrupted due to the caliber change of the membrane tube 144; the inlet of the duckbill valve is communicated with the outer through hole of the outer bottom plate; the glue outlet of the duckbill valve is always abutted against the surface to be glued; the glue outlet ranges of the duckbill valves cover all the surfaces to be glued, and the glue outlet ranges of different duckbill valves are not overlapped.
The working principle of the gluing unit 10: because the inner side surface of the outer plate is not equidistant to the axis of the gluing box 11, when the glue outlet of the duckbill valve is abutted against the surface to be glued, the pipeline 14 needs to stretch; when the pipeline 14 is shortened, the caliber of the pipeline 14 is shortened, so that the containing space in the pipeline 14 is unchanged, and the problems of uneven and discontinuous glue outlet caused by the caliber change of the pipeline 14 are avoided; if the caliber is not reduced when the pipeline 14 is extended, the glue outlet quantity of the glue outlet is reduced or even interrupted; if the caliber is not increased when the pipeline 14 is shortened, the glue outlet quantity of the glue outlet is increased suddenly; when the gluing box 11 rotates around the gluing box, the telescopic motor 12 always works, the extrusion plate 13 always and uniformly moves upwards, and hot-pressed glue in the glue storage chamber is uniformly discharged to the corresponding pipeline 14; in order to achieve that the length variation of the pipeline 14 is proportional to the caliber variation, it can be ensured by setting the radian and elasticity of the elastic arc plate.
The working flow of the hot press gluing equipment is as follows:
s1, placing an outer plate on a left moving plate 1, and automatically gluing;
S2, pushing the left moving plate 1 onto the operating table 2;
s3, after the left moving plate 1 completely enters the operation table 2 and is stabilized, the clamping hand 4 descends and clamps the outer plate;
S4, starting the press falling safety device and the outer plate product falling safety device, and enabling the clamping hand 4 to clamp the outer plate to move upwards;
s5, after the outer plate moves upwards to be stable, the left moving plate 1 slides out of the operating platform 2, and the right moving plate 3 bearing the lining moves into the operating platform 2;
s6, the clamping hand 4 clamps the outer plate to be lowered to be attached to the inner lining;
s7, die assembly, heating and heat preservation are carried out for 10 minutes;
s8, starting a press falling safety device, and loosening the clamping by a clamping hand 4 and moving upwards;
s9, after the clamping hand 4 moves upwards to be stable, the right moving plate 3 bears the outer plate-inner liner assembly to slide out of the operating platform 2;
And S10, taking out the outer plate-inner liner assembly.
It should be noted that the process of attaching the liner to the right shift plate may be performed in any of steps S1 to S4; if the hot press gluing equipment is in a circulation mode, the process of moving the new left moving plate 1 into the operation table 2 is carried out simultaneously with the step S10; if the thermocompression bonding apparatus is in the circulation mode, the process of placing the new outer board on the left shift board 1 may be performed in any of steps S6 to S10.
