Film is sucked, to further be recycled.
The course of work and principle of the present embodiment:
By higher level's transmitting device (such as manipulator, conveyer belt, artificial), by organic LED display panel according to
Setting position is placed on 4 upper surface of absorptive table, vacuum is provided to absorptive table 4, by organic LED display panel according to setting
Positioning, which is set, is fixed on 4 upper surface of absorptive table.Start conveyer mechanism 2, opens laser heating element 5, the effect heated by laser
Rate control conveyer mechanism 2 conveyer belt transmission speed, by organic light-emitting diode display plate lead district protective film with have
Binder between machine light-emitting diode display panel lead district sufficiently heats, and the adhesion strength that protective film is greatly reduced (needs
Pay attention to when, when heating, cannot damage viewing area lead district).
Continue to convey organic light-emitting diode display plate to the right, and moves down peel plate 7 while passing through heating container 12, heating
Circulating pump 13 provides heat medium to heating chamber 10, holds the hot melt adhesive in sebific duct 8 to metal and carries out heating fusing, gives at the same time
Vacuum chuck 18 provides vacuum.When plate 7 to be stripped is contacted with protective film, vacuum chuck 18 takes the lead in adsorbing protective film,
Conveyer mechanism 2 stops conveying, closes heat cycles pump 13.(it is less than 1s) after a period of time, starts coolant circulation pump 15, it will be cold
But the cooling medium of medium storage tank 14 is sent into cooling chamber 11, is quickly cooled down to hot melt adhesive, is made its instantaneous solidification, firmly cling guarantor
Protect film.
After a period of time (1s or so), peel plate 7 is moved up, and is continued to there is conveying, it is viscous due to peel plate 7 and protective film
The adsorption capacity of relay and vacuum chuck 18 is greater than bonding between organic light-emitting diode display plate lead district and its protective film
Power, so that protective film be removed.After being fully removed the region of 7 face conveyer belt of peel plate for be adsorbed 4, absorptive table 4 is removed
Vacuum organic light-emitting diode display plate is taken out, and remove by downstream transmission device (such as manipulator, conveyer belt, artificial)
It goes the vacuum of vacuum chuck 18, close coolant circulation pump 15, while starting heat cycles pump and providing heating to heating chamber 10 again
Medium, the bonding force reduced between peel plate 7 and protective film take down protective film (such as manipulator, people by downstream unit
Work), complete the removing of organic light-emitting diode display plate lead district protective film.
Conveyer mechanism 2 is finally controlled, absorptive table 4 is returned, to carry out stripping next time.To improve working efficiency, in reality
In the production of border, multiple absorptive tables 4 can be arranged side by side, laser heating element 5, the peel plate of corresponding setting and 4 equivalent of absorptive table
7。
Above-described specific embodiment, to the purpose of this utility model, technical scheme and beneficial effects carried out into
One step is described in detail, it should be understood that being not used to limit the foregoing is merely specific embodiment of the present utility model
Determine the protection scope of the utility model, within the spirit and principle of the utility model, any modification for being made equally is replaced
It changes, improve, should be included within the scope of protection of this utility model.
