The device of this embodiment is in use: according to the standard thickness of the slurry coated on the substrate, the pressure sensing value between the coating roller 503 and the pressure sensor 604 is set as X, when the slurry with strong fluidity is coated on the substrate by the coating roller 503, the slurry on the substrate is coated too much, when the slurry is rolled on the substrate by the coating roller 503, the area corresponding to the flexible pad 605 and the substrate is extruded and deformed downwards, the pressure sensor 604 detects that the pressure value is higher than X, for the area, the first valve 7062 is closed, the second valve 7064 is opened, the liquid suction cover 7066 and the suction pipe 7063 are driven to move to the corresponding position by the electric sliding rail 7071, simultaneously, one end of the pressing plate 703 close to the electric sliding rail 7071 is moved downwards by the third cylinder 708 in cooperation with the rotary groove 711 and the rotary column 712, at this time, the distance between the bottommost end of the pressing plate 703 and the upper surface of the substrate is the standard thickness of the coated slurry, when the slurry with the standard thickness higher than the coated slurry is rolled on the substrate, the slurry is scraped off to the inside of the strip-shaped groove 7065 by the pressing plate 703, then the two-way pump cooperation 706 and the suction pipe 7063 are sucked upwards, the suction pipe 7068 is sucked up by the two-way pump cooperation 706 and the suction pipe 7068, and the suction pipe 7068 is sucked into the strip-shaped 7063 by the suction pipe 7063 when the suction pipe 7068 is moved away from the liquid suction pipe 7063.
When the coating amount of the slurry with weaker fluidity is smaller than the standard thickness of the slurry after the slurry is coated on the substrate along with the rotation of the coating roller 503, and when the pressure sensor 604 detects that the pressure value is smaller than X, the first valve 7062 is closed and the second valve 7064 is opened for the area, the electric sliding rail 7071 drives the liquid suction cover 7066 and the suction pipe 7063 to move to the corresponding position of the area, then the bidirectional pump is matched with the communicating pipe 706 and the suction pipe 7063 to blow downwards, the extrusion column 7068 moves towards one end close to the liquid suction cover 7066, the slurry temporarily stored in the suction pipe 7063 is extruded into the area with smaller slurry coating, and the excessive slurry is smoothed immediately when the bottom end of the pressing plate 703 is scratched after the coating.
When solid particles in the slurry are blocked at the bottom of the inner side of the scraper 303 in the rotating process of the coating roller 503, the coating roller 503 can not coat the slurry at the corresponding position of the substrate and the solid particles due to the blocking of the solid particles in the rotating process, the problem of continuous leakage foil can occur on the substrate, if the slurry is not stored in the suction pipe 7063, the problem that the spare slurry cannot be absorbed in the suction pipe 7063 to fill the defect is solved, the leakage foil area is not coated with the slurry with equal thickness due to the surface of the substrate, so the pressure value detected by the pressure sensor 604 is smaller than X, when the area moves to the strip-shaped groove 7065, the bi-directional pump is matched with the communicating pipe 706 and the suction pipe 7063 to blow down, the extruding column 7068 and the corrugated pipe 7069 are pushed to move towards the direction of the liquid suction cover 7066 by the air pressure, when the corrugated pipe 7069 contacts with one side of the liquid suction cover 7066, the pressure release valve 7070 and the liquid suction cover 7066 are pushed by the air pressure, at this time, the pressure release valve 7070 is opened, and the slurry in the corrugated pipe 7069 is discharged towards the non-coated area of the strip-shaped groove 7066.
It should be further noted that, if a certain pressure sensor 604 continuously detects that the pressure value is smaller than X, in addition to the subsequent trowelling of the slurry in the area, the solid particles at the positions corresponding to the area of the coating roller 503 and the scraper 303 should be cleaned in time.
When the substrate deviates in the slurry coating process, the photoelectric sensors 205 at the top of the telescopic column 204 are used for detecting the deviation direction of the substrate on the telescopic column 204, specifically, the two photoelectric sensors 205 at the top of the telescopic column 204 are used for detecting the position of the substrate at the same time, when the substrate deviates, one photoelectric sensor 205 is shielded by the substrate, the light reflection quantity received by the photoelectric sensors is reduced, and at the moment, the telescopic column 204 is driven to move outwards by the second electric push rod 203 corresponding to the other photoelectric sensor 205, so that the position of the deviated substrate is corrected and reset.
In addition, when the substrate is wrinkled, the thickness of the creased area of the substrate will be increased, the thickness of the slurry coating of the folded area of the substrate cannot reach the standard, and the partial area cannot be contacted with the slurry, so that when the substrate is wrinkled, two sides of the substrate will shift on the flexible pad 605, the width of the flexible pad 605 satisfies the detection of the offset of the substrate, when the substrate is wrinkled, one side of the substrate, which is wrinkled inwards, will shift inwards, at the moment, the pressure value of the pressure sensor 604 corresponding to the area shifted by the substrate is reduced, meanwhile, because the substrate is folded inwards, the pressure value of the pressure sensor 604 of the folded area of the substrate is kept in an improved state, when the two conditions are satisfied, the substrate is firstly judged to be wrinkled, then the telescopic column 204 is synchronously driven upwards by the two first electric push rods 202, the friction force between the telescopic column 204 and the substrate is improved, then the telescopic column 204 is driven to move outwards by the second electric push rods 203, the telescopic column is driven to expand, when the folded area of the substrate is moved to the strip-shaped groove 7065, the electric slide rail 7071 drives the cover 7066 and the suction pipe 7063 to move to the position corresponding to the position of the suction pipe 7063, and the suction pipe 7063 is continuously extruded to the inner end of the suction pipe 7068 is filled with the suction pipe 7063.
It should be further noted that, when the crumpled area is filled and smoothed, the crumpled area is irregularly shaped, so that the extrusion of the slurry should meet more or less requirements, and the excess slurry is sucked into the suction pipe 7063 again after the slurry coating on the substrate is completed.
