The present invention leads to have remaining cleaning since transfer plate is hanging type cleaning for existing transfer plate cleaning device
Solvent hold-up will lead to that APR board bottom portion is cracked in APR board bottom portion after dry, to influence the effect of subsequent PI liquid printing.
The present embodiment is able to solve the defect.
A kind of 60 cleaning device of transfer plate, as depicted in figs. 1 and 2,60 cleaning device of transfer plate includes for moving
51 structure 50 of hauler of transfer plate 60 further includes the spraying mechanism 10 for transporting route setting along transfer plate 60, Wiping mechanism 20, surpasses
Sound wave wiper mechanism 30 and blower mechanism 40.By multiple working procedure, reaches and be preferably cleaned and dried effect.
The spraying mechanism 10 includes spray groove 11 and sprinkler part, spray to transfer plate 60 by sprinkler part clear
It washes, the cleaning solution for accommodating and falling on transfer plate 60 is accepted by spray groove 11, cleaning solution is recycled, guarantees working environment
Neatly, contaminated cleaning solution environment is prevented.
Specifically, the sprinkler part includes first spray head 12, the first spray head 12 is vertically arranged, to transfer plate
60 transfer surface 61 carries out spray cleaning.When carrying out spray cleaning to transfer plate 60, transfer plate 60 is horizontally arranged, passes through first
Spray head 12 carries out spray cleaning to transfer plate 60, removes remaining PI liquid on transfer plate 60, while preventing cleaning solution to be trapped in and turning
The effect of the subsequent PI liquid printing of 60 plate bottom influences of printing forme.
Specifically, the first spray head 12 is set in spray groove 11 and the first spray head 12 is arranged upward, with contraposition
Transfer surface 61 in 60 lower part of transfer plate carries out spray cleaning.
Typically, since technological design demand, the convex of netted arrangement can be provided on the transfer surface 61 of existing transfer plate 60
Peak 62 will form groove between adjacent convex peak 62, and when cleaning transfer plate 60, the transfer surface 61 of transfer plate 60 is placed downward,
When transfer plate 60 is by wiper mechanism, after being cleaned by 12 upward spraying cleaning solution of first spray head to transfer surface 61, residual
Cleaning solution on transfer surface 61 is fallen under the effect of gravity, so that remaining cleaning solution accumulation is prevented in a groove, to reach
Better cleaning effect.
Wherein, the spray groove 11 is fixedly arranged above horizontally disposed liquid barrier 14, the liquid barrier 14 and spray groove 11
Between have accommodate transfer plate 60 gap.
The sprinkler part further includes the second spray head 13 being set on liquid barrier 14, and the second spray head 13 is arranged downward
Or be arranged upward, to carry out spray cleaning to transfer plate 60.Between transfer plate 60 is moved between liquid barrier 14 and spray groove 11
After gap, is combined by first spray head 12 with second spray head 13, the transfer surface 61 and upper side of transfer plate 60 are cleaned, thus
Reach better cleaning effect.
It should be noted that the first spray head 12 and second spray head 13 can be stationary nozzle, it can also be rotary nozzle.

After printing forme 60 is cleaned, the transfer surface 61 of transfer plate 60 is wiped by the first round brush 21, removal remains on transfer plate 60
Residual liquid prevents residual liquid from influencing the effect of subsequent PI liquid printing.
The polishing piece further includes the second round brush 22 that 21 top of the first round brush is set side by side and be located at the first round brush 21,
First round brush 21 can with transfer surface 61 opposite face contact, to wipe the opposite face of transfer surface 61.In this preferred embodiment
In, the opposite face of transfer surface 61 is the upper side of transfer plate 60, and the upper side of transfer plate 60 is wiped by the second round brush 22, is gone
Except the residual liquid on upper side, prevent the residual liquid of 60 upper side of transfer plate from flowing on transfer surface 61.
It should be noted that in the preferred embodiment, first round brush 21 and the second round brush 22 are soft hairbrush.
The bristle that continental quilt bristle paints is more convenient for clearing up the Liquid Residue of residual in a groove, to transfer plate 60 be wiped more dry
Only.
The blower mechanism 40 includes being obliquely installed to remove the blowing component of residual liquid on transfer plate 60, the blowing
Component includes upper air knife 41 and lower air knife 42, and by drying, the transfer plate 60 after ultrasonic cleaning is blowed in component,
It blows the residual liquid on transfer plate 60 off, prevents the effect for influencing subsequent PI liquid printing.
51 structure 50 of hauler includes support arm 52 and the hauler 51 for transporting support arm 52,52 edge of support arm
Vertically arranged, the transfer plate 60 is arranged on support arm 52.
It should be noted that the hauler 51 can position belt conveyor, can also be chain-linked conveyer, in this preferred implementation
In, the hauler 51 is chain-linked conveyer.The support arm 52 is fixedly connected with the carrier chain of hauler 51, passes through hauler
51 drive transfer plate 60 successively to pass through various processes.
It should be noted that the hauler 51 may be provided above or below spray groove 11, in the preferred embodiment,
The hauler 51 is arranged below spray groove 11.
Wherein, as shown in figure 3, be fixed on the support arm 52 driving transfer plate 60 along perpendicular to transport direction level move
Dynamic actuator 53, the actuator 53 can be electric cylinders, cylinder or hydraulic cylinder；The telescopic rod 531 of the actuator 53 is along vertical
Horizontally disposed in transporting direction, the transfer plate 60 is removably connected to telescopic rod 531 by fixing pieces such as buckles.Pass through spray
When mechanism 10 carries out spray cleaning to transfer plate 60, transfer plate 60 is driven to move along 531 axial reciprocating of telescopic rod by actuator 53
It is dynamic, to reach better cleaning effect, while making to remain in transfer plate 60 by the shake that transfer plate 60 moves back and forth generation
On liquid fall, prevent liquid from remaining on transfer plate 60.
A kind of cleaning method of transfer plate 60, is cleaned using above-mentioned cleaning device, the cleaning method include with
Lower step：
S10, spraying mechanism 10 first spray head 12 spray cleaning is carried out to horizontal positioned transfer plate 60 using cleaning solution；
S20, Wiping mechanism 20 polishing piece to spray cleaning after transfer plate 60 wipe, to remove on transfer plate 60
Residual liquid；
Wherein, the first spray head 12 is vertically arranged, and the polishing piece is laterally arranged.
Wherein, in a preferred embodiment, it after step S20, is transferred by 30 Duis of ultrasonic cleaning agency
Plate 60 carries out ultrasonic cleaning.Before carrying out secondary cleaning to transfer plate 60 using ultrasonic cleaning agency 30, gone by polishing piece
Except remaining cleaning solution on transfer plate 60, so that ultrasonic cleaning be made to reach better effect.
In another preferred embodiment of the present invention, before step S20, by ultrasonic cleaning agency 30 to transfer plate 60
Carry out ultrasonic cleaning.Transfer plate 60 is cleaned again by ultrasonic cleaning agency 30, it is residual on transfer plate 60 to remove
After the cleaning solution stayed, polishing piece wiping transfer plate 60 is reused, to reach better drying effect.
Wherein, after carrying out ultrasonic cleaning to transfer plate 60 by ultrasonic cleaning agency 30, pass through blower mechanism 40
