Description

Technical Field

[0001] The present invention relates to the field of heating equipment, and in particular to a curing furnace, product baking and conveying equipment and a processing method. Background Art

[0002] At present, the curing and baking for 3C, automotive electronics, and semiconductor industries in the market mostly use vertical curing furnaces. The products of 3C, automotive electronics, and semiconductor industries need to meet relatively special heating conditions when heating, otherwise it will affect the curing of the glue (different glues used in products have different curing times, temperatures, and other conditions), which will in turn affect product quality, cause waste, and increase production costs.

[0003] Existing vertical curing furnaces have the following disadvantages: 1) The vertical curing furnace has a cavity space for accommodating products, which is large, the baking temperature fluctuates greatly, the heating uniformity of each product is poor, and the failure rate is high; 2) The number of products stored in the vertical curing furnace is limited, which is not conducive to batch processing and affects production efficiency; 3) The baking time cannot be set, and the baking time is limited, and some products require a longer baking time; 4) A constant temperature is set in the vertical curing furnace, and the product will receive thermal shock when entering the furnace (before entering, the product temperature is lower than the temperature in the furnace) and when exiting the furnace after heating (when exiting, the product temperature is higher than the external environment temperature), which affects the product quality; 5) When the product is heated in the curing furnace for a preset time and needs to be taken out and transferred to the subsequent process, if the equipment used in the subsequent process fails, causing the product to be stranded in the curing furnace and unable to be transferred, continuing to heat the product will greatly affect the product quality; 6) It is too dependent on the environment and is not scalable. It is impossible to add intelligent modules such as data acquisition and communication modules, and it is impossible to achieve intelligent control.

[0004] In addition, during the entire operation process of the product from loading, heating, to output, there is a dependency relationship between the various devices involved. If a problem occurs in a certain device, the equipment involved in the subsequent process needs to be stopped. For example, a sudden stop of the entire line or a failure cannot be dealt with (once a stop or failure occurs at the back end of the line, the panel must be manually forced to be arranged), maintenance is difficult, which greatly affects product quality and production efficiency, and cannot achieve automated production.
