Detailed Description

As shown in fig. 1 and 2, the baking box with the flat-lift cover for the display substrate is provided with an upper cover 1 at the opening of the baking cavity of the baking box body 8, the baking box body 8 is a rectangular opening box body with an upward opening surrounded by the surrounding box walls and the box bottom, and correspondingly, the upper cover 1 is also a rectangular plate-shaped cover. The baking box wall, the baking box bottom plate and the baking box upper cover 1 of the baking box body 8 are all composed of an aluminum alloy section bar framework and a panel, and heat preservation and insulation materials are filled between the framework and the panel so as to improve the strength and the heat insulation performance of the baking box wall, the bottom plate and the upper cover. Two baking box doors 3 are arranged on the box wall of the baking box body 8 and are used for feeding and removing the baking glass substrate. Two baking oven doors 3 are positioned on two adjacent box walls of a baking oven body 8, the baking oven doors 3 are arranged on an oven door swing shaft 5 through an oven door swing rod 4, two ends of the oven door swing shaft 5 are both connected with an oven door swing shaft cylinder 6 used for driving the oven door swing shaft 5, and the oven door swing shaft cylinder 6 is a blade type swing cylinder and can also be a telescopic swing cylinder or a gear rack swing cylinder. The baking oven body 8 is supported on two parallel sliding guide rails 7 in a sliding way.

As shown in fig. 3, a toaster case support frame 9 for fixedly mounting a toaster case body 8 is slidably supported on the slide rails 7 by means of a frame slide 10. The baking box supporting frame 9 is fixedly connected into a plate frame structure by aluminum alloy sections, and two opposite side edges of the baking box supporting frame 9 are respectively and correspondingly provided with two parallel sliding guide rails 7. Two carriage slides 10 are mounted on each side of the oven supporting frame 9, and the side oven supporting frame 9 is supported on the sliding guide 7 of the corresponding side by the two carriage slides 10. The two sliding guide rails 7 are arranged in parallel, and the sliding guide rails 7 are common linear sliding guide rails.

As shown in fig. 4, upper cover horizontal lifting pins 2 are fixedly mounted at four corners of an upper cover 1 of the oven, and the upper cover horizontal lifting pins 2 are supported on corresponding support plates of the horizontal lifting cylinders 11; the four corners of the upper cover 1 of the baking oven are also provided with flat-pressing cylinders 12 which can be vertically and horizontally pressed downwards, and the flat-lifting cylinder 11 and the flat-pressing cylinder 12 are arranged at the four corners of the upper cover 1 of the baking oven in pairs.
