Since the pressing head 302 will be heated and have a downward pressure, the spacer cloth 308 will form a separation component between the pressing head 302, the liquid crystal panel and the FPC when pressed down. The pressing head 302 first presses down the spacer cloth 308, and the liquid crystal panel and the FPC are bonded by the spacer cloth 308.

[0075] The first manipulator 401 grabs the raw material on the loading position and installs it to the attachment position, and the attachment mechanism 1 performs ACF104 attachment on the raw material to obtain the preliminary material;

[0076] The second manipulator 402 transfers the preliminary material from the attachment position to the pre-pressing position, and the pre-pressing mechanism 2 pre-presses the preliminary material to obtain the intermediate material;

[0077] The third manipulator 403 transfers the intermediate material from the pre-pressing position to the first main pressing position, and the main pressing mechanism 3 performs main pressing on the intermediate material to obtain the cost material; wherein, after the intermediate material is reshaped at the pre-pressing position, the third manipulator 403 transfers the next intermediate material to the next main pressing position;

[0078] The fourth robot 404 transfers the finished material from the current pressing position to the unloading position.

[0079] The above is a specific description of the preferred implementation of the present invention, but the invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
