[0062] Embodiment Six

[0063] The using method of the laminating machine of the present invention includes the steps:

[0064] S1. Place the tray carrying the screen to be laminated on the feeding conveyor line 1, and the end blocking part positions the tray.

[0065] S2. The panoramic CCD camera takes a panoramic photo of the tray. The loading manipulator 4 moves the screen to be laminated in the tray to the attaching platform 22 according to the shooting result of the panoramic CCD camera. The screen to be laminated is placed on the attaching platform 22 and is adsorbed and fixed, and the attaching platform 22 moves towards the discharging conveyor line 3 to the laminating station.

[0066] S3. The rolling head 83 adsorbs the membrane on the film tearing module 7 and moves above the attaching platform 22. Through the positions of the screen to be laminated and the membrane provided by the screen correction CCD camera and the membrane correction CCD camera, the adjusting assembly adjusts the position of the rolling head 83.

[0067] In step S4, the rolling attachment head 83 performs the film laminating operation on the screen to be laminated and the film; meanwhile, the lower plate manipulator 5 moves the tray without the screen to be laminated on the feeding conveyor line 1 to the discharging conveyor line 3.

[0068] In step S5, the attaching platform 22 moves to the end close to the discharging conveyor line 3, and the blanking manipulator 6 moves the screen that has completed the film laminating operation to the tray on the discharging conveyor line 3.

[0069] In step S6, steps S1 - S5 are repeated until the bottom of the lowermost tray on the bracket 92 contacts the discharging conveyor line 3, and the discharging conveyor line 3 is started to simultaneously transport multiple stacked trays out.

[0070] In step S2, the attaching platform 22 moves to one end away from the discharging conveyor line 3 to wait for receiving the screen to be laminated.

[0071] It should be noted that when the rolling attachment head 83 adsorbs the film on the film tearing module 7, the second lifting cylinder 86 retracts so that the roller 838 does not exceed the position of the film adsorption plate 87, and the film adsorption plate 87 is in a horizontal state to adsorb and pick up the film, so that the film is in a natural flat state. At the same time, the length of the film adsorption plate 87 is less than the length of the film, that is, the film at the corresponding position of the roller 838 is in a suspended state.

[0072] When performing the film laminating operation in step S4, the first lifting cylinder 85 retracts to make the film adsorption plate 87 inclined. The height of the film adsorption plate 87 close to the roller 838 is less than the height of the film adsorption plate 87 away from the roller 838. The second lifting cylinder 86 extends, and the roller 838 moves down to contact the film and further presses the film on the screen to be laminated. Through the adjustment and movement of the second linear adjustment member 82 and / or the attaching conveyor line 2, the roller 838 rolls the film from one end of the screen to be laminated to the other end, finally realizing the film laminating operation, preventing bubbles from being generated during the film laminating process, and being beneficial to improving the processing efficiency and quality.

[0073] Meanwhile, in step S6, the bracket 92 moves down according to the weight detected by the weight sensor 95, so that when the blanking manipulator 6 moves the screen that has completed the film laminating operation to the tray on the discharging conveyor line 3, the trays receiving the screen are all at the same height, facilitating the safe placement of the screen.

[0074] Specifically, it is set according to the weight of a single tray. The calculation formula for the descending height a:

[0075]

[0076] Wherein, G is the detected weight of the weight sensor 95, g is the weight of a single tray, g' is the weight of the screen after the film covering operation is completed, and b is the thickness of a single tray.

[0077] The bracket 92 is initially in an initial state. When a tray without a screen to be film-covered is placed on the bracket 92, the bracket 92 does not move. When a screen after the film covering operation is placed on the tray, the bracket 92 moves downward. Generally, by rounding down the quotient of G and g + g' through this calculation formula, the control of the movement adjustment of the bracket 92 can be completed.

[0078] The above are only the preferred embodiments of the present invention, which are illustrative rather than restrictive to the present invention. Those skilled in the art understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, but all will fall within the protection scope of the present invention.
