Abstract

The invention relates to a PI pre-curing machine which comprises a worktable. A conveying device is arranged on the upper surface of the worktable and is sequentially divided into a feeding section, a heating section and a discharging section in the conveying direction, a heating device is arranged above the heating section, a heating plate is arranged at the bottom of the heating device, downward heat radiation of the heating plate can be used for pre-curing treatment on PI printed on a substrate, the conveying device can make the substrate sequentially pass through the feeding section, the heating section and the discharging section, a camera for monitoring the substrate transfer situation on the discharging section is arranged at the end, away from the heating device, of the discharging section, a controller is arranged on the worktable or heating device and is electrically connected with the camera and the conveying device, and the controller can receive image information transmitted by the camera and control startup and shutdown of the conveying device. The PI pre-curing machine has the advantages that continuous feeding and discharge g can be achieved and is higher in PI pre-curing efficiency and automation degree compared with the traditional mode that shutdown and discharging are performed and then recharging is performed after pre-curing is completed.

Description

technical field [0001] The invention belongs to the field of LCD front-section production, and in particular relates to a PI pre-curing machine. Background technique [0002] PI alignment film is a film with straight scratches, the effect is to guide the orientation of liquid crystal molecules. On the glass substrate on which the transparent conductive film has been steamed, use PI coating liquid and a rotary wheel to print a strip of parallel grooves on the ITO film, and then pre-cure and cure. Alignment film pre-curing equipment is a device that heats the substrate at medium and low temperatures after the alignment film is printed and before high-temperature curing, so that the alignment film is dried and pre-cured. The usual pre-curing method of pre-curing equipment in the prior art is to place the substrate on a hot plate for pre-curing. The hot plate is fixed, so the efficiency of its automatic continuous production is low. Contents of the invention [0003] The pre...
