It on platform 13, avoids during sprayed glues, display or the appearance local deformation of touch module 20.
Display or touch module 3D printing glue-line method further include step 6), and laser head will be cured glue to print platform 13
The display or touch module 20 of layer carry out reinspection scanning, and laser head is along display or length direction and the width side of touch module 20
To multiple straight line path scanning is carried out, detection is shown or the reinspection altitude information of the connecting end surface upper glue layer of touch module 20, into
And according to the initial survey altitude information of connecting end surface and the reinspection altitude information of glue-line, obtain the high degree of glue-line of the glue-line of printing
According to.
Above-mentioned steps 3) in laser head scan path it is consistent with the scan path of the laser head in step 6), in this way,
Controller then can carry out judgement comparison, be accurately somebody's turn to do according to the initial survey altitude information and reinspection altitude information of same position
The bondline thickness of position can more accurately realize that glue-line prints.
In the step 3), while to the display or the progress position correction of touch module 20 on print platform 13, pass through
Correcting structure carries out detection correction to the position of display or touch module 20；Correcting structure includes four camera shootings arranged downward
Head, four cameras carry out coordinate position detection to four corners of display or touch module 20 respectively, and it is anti-to will test data
It feeds controller, and then is shown or 20 Centre location data of touch module and tilt angle data, controller is according to need
It wants, control print platform 13 is mobile, to adjust the position of display or touch module 20.
The present embodiment additionally provides display or touch module 3D printing glue-line equipment, for realizing above-mentioned display or touching
Mould group 3D printing glue-line method is controlled, including above-mentioned dyestripping platform 12, dyestripping structure 10, transit plate 11, print platform 13, glue
Printing device 14, curing apparatus 15 and laser head.
The display or 20 feeding of touch module for being stained with protective film are placed on dyestripping platform 12, and it is flat to be attracted to dyestripping
On platform 12, dyestripping structure 10 tears the protective film in display or touch module 20, and transit plate 11 will be aobvious on dyestripping platform 12
Show or touch module 20 is transferred on print platform 13, and be attracted on print platform 13, laser head is on print platform 13
Display or the connecting end surface of touch module 20 carry out multiple linear scanning, obtain initial survey altitude information, controller obtains initial survey
Altitude information, after print platform 13 will be shown or touch module 20 is moved in glue printing device 14, controller controls glue
Multiple glue spray heads of water printing device 14 are in display or the connecting end surface sprayed glues of touch module 20, that is, 3D printing glue
Layer, the initial survey altitude information that controller is detected according to laser head, the different the amount of injection of the glue spray head of corresponding control different location
And jet velocity etc., so as to spray the glue of different-thickness according to different location on connecting end surface；After spraying glue-line
Display or touch module 20 be moved in curing apparatus 15 by print platform 13, curing apparatus 15 to the glue-line on connecting end surface into
Row solidification.
The display or touch module 3D printing glue-line equipment of above-mentioned offer, using transit plate 11 by dyestripping on dyestripping platform 12
Display or touch module 20 afterwards is transferred on print platform 13, and display or touch module 20 carry out glue-line on print platform 13
3D printing avoids during glue-line 3D printing, and the phenomenon that local deformation occur in display or touch module 20；Utilize laser head pair
The connecting end surface of display or touch mould group after dyestripping carries out a plurality of straight line path scanning, obtains initial survey altitude information, controller
The glue spraying that the different glue spray heads of control glue printing device 14 can then be corresponded to, so that being formed in display or touch module 20
Connecting end surface on glue-line upper surface it is smooth, avoid the occurrence of rugged defect.
In the present embodiment, in above-mentioned step 1), display or touch module 20 utilize wind before carrying out dyestripping operation
Knife structure cleans the protective film in display or touch module 20, in this way, avoiding on protective film during dyestripping
Dust etc. is fallen on the connecting end surface of display or touch module 20.
There is insufflation channel and air intake passage, air knife structure has the lower end arranged downward, under this in air knife structure
End show downward or touch module 20 on protective film arrangement, the lower end of air knife structure has inflatable mouth and air entry,
Inflatable mouth be connected to insufflation channel, air entry be connected to air intake passage, and along show or touch mould group moving direction, inflatable mouth and
Air entry sequentially arranged for interval, in this way, after inflatable mouth blows afloat the dust etc. on protective film, air entry will then raise in time
Dust etc. sucks in air intake passage.
Along direction from bottom to top, insufflation channel is obliquely arranged, and deviates air intake passage arrangement, in this way, blowing
When, it is ensured that inflatable mouth is blown towards display or 20 moving direction of touch module, convenient for dust for raising etc. by air-breathing
Mouth sucking.
Air intake passage arrangement in a vertical shape, and there is dust-collecting cavity in air knife structure, dust-collecting cavity deviates air intake passage arrangement,
And be connected to air intake passage, in this way, the dust etc. sucked by air entry, then can be incorporated in dust-collecting cavity.
In the present embodiment, the lower end of air knife structure has the gap regions being recessed upward, and the air entry of air intake passage is then
It is formed in the gap regions, in this way, being conducive to sucking of the air entry to the dust raised.
