Full-automatic curing furnace for visual panel screen printing drying

Abstract

The invention relates to a full-automatic curing furnace for visual panel screen printing drying in the field of drying and curing heating furnaces. The full-automatic curing furnace comprises a feeding device used for pushing material trays to enter the furnace, a material supporting device used for supporting the material trays fed into the furnace one by one and stacking the material trays intoa material tray stack, a conveying device used for conveying the material tray stacks to the other side in the furnace from one side in the furnace, a lifting device used for lifting the material tray on the uppermost layer in the material tray stack to be correspondingly horizontal to a discharging opening, a discharging device used for taking out the material trays from the furnace, a materialtray conveying device used for conveying the taken-out material trays to the lower portion of the furnace tail and a material lifting device used for lifting the material trays to a furnace feeding opening after panels to be dried and cured are placed in the empty material trays. The curing furnace is small in occupied area and can carry out online continuous production, product quality stabilitycan be guaranteed, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to the field of drying and curing heating furnaces, in particular to a fully automatic curing furnace for drying screen printing on the appearance of mobile phone touch screens or other visible panels, which is suitable for baking in spraying, brushing and screen printing processes Curing furnace production line. Background technique [0002] As we all know, most people now rely more and more on mobile phone electronic products in their daily life, so high-quality mobile phone electronic products have become the common goal of all manufacturers and consumers, among which: the screen panel is an indispensable part of mobile phone electronic products In the production process, silk screen printing is an indispensable process in the production of screen panels. The appearance of mobile phone touch screens and other visible panels must undergo silk screen printing, spraying, brushing and other processes, and then be dried and cured. ...

AI Technical Summary

Problems solved by technology

[0003] 1. The box-type electric oven / electric oven is used in a periodic manner, that is, it can only perform intermittent baking operations one box at a time when baking products, which makes it incompatible with silk screen printing, spraying, and brushing. Coating and other process equipment are connected to the production line, resulting in low operating efficiency; at the same time, the wiring of the box-type electric oven / electric oven is concentrated and set up in an independent area, which cannot be connected with the wiring of the process process equipment, which is not convenient for the application. The overall wiring layout during installation; in addition, when the box-type electric oven / electric oven is used, the baking operation takes a long time, and is affected by the opening and closing of the oven / box door when entering and leaving the oven / box. A large amount of temperature will be emitted and flowed to the production site, which will not only cause waste of energy consumption, but also lead to prolonged heating time and unstable temperature, thereby reducing production efficiency and making it difficult to control the baking quality;

[0004] 2. In the practical application of box-type electric oven / electric oven, in order to facilitate the transfer of products, it must be equipped with multiple multi-layer racks during baking to prepare for the turnover of baked products. However, the machine and box-type The turnover distance between electric oven / electric oven is relatively long, which requires that the production site must provide enough turnover space. At the same time, even when these shelves are not in use, they will occupy more area and space. Space, thus bringing corresponding trouble and inconvenience to the management side;

[0005] 3. The electric heating tunnel drying and curing furnace, commonly known as the tunnel furnace, in practical applications, in order to facilitate the smooth entry and exit of products, the two ends of the tunnel furnace are basically designed to be open. However, such a structure is bound to Make the heat in the furnace overflow, and increase the temperature of the working environment in the process of spreading to the surroundings, resulting in waste of energy and certain thermal pollution; in addition, the tunnel furnace uses a dynamic transmission method for drying and curing, and its open The two ends of the furnace body are not conducive to maintaining the thermal energy in the furnace body in a stable range in practical applications, that is, the set temperature of the tunnel furnace and the actual temperature of the radiation on the product that needs to be dried and cured in the furnace will have a large difference. , the temperature in the tunnel furnace will also be affected by the air temperature outside the furnace, resulting in large temperature fluctuations, and these factors will affect the stability of the drying and curing process, making it difficult to fully meet the requirements of the production process;

[0006] 4. The electric heating tunnel drying and curing furnace transports the product through the conveyor belt at a certain speed during work, that is, the product is placed on the conveyor belt and sent into the tunnel furnace entrance, and the product is pressed by the operation of the conveyor belt In the process, the tunnel furnace dries or solidifies the products on the conveyor belt; in actual operation, the mobile phone touch screen and other visible panel products are placed on the conveyor belt in the form of tiles. In addition, the drying or curing process of these products takes a certain amount of time, so it is necessary to design a longer tunnel furnace body to meet the requirements of the product drying process, but this will inevitably increase the floor space of the tunnel furnace. Moreover, if trays are used to place products, the setting of the tray return system must also be considered, which results in a larger overall floor area of ​​the tunnel furnace, more difficult connection and management, and high production costs; if Reducing the length and width of the tunnel furnace, although it can reduce the floor area accordingly, is convenient for setting up the connection and management, but it cannot effectively meet the baking process requirements of the product;

[0007] To sum up, both the box-type electric oven / electric oven and the electric heating tunnel drying and curing oven have the defects of large floor area, inability to carry out continuous production on-line, and difficulty in fully ensuring stable quality and low production efficiency.
