Description

Technical Field

[0001] The utility model relates to the technical field of curing furnaces, and particularly relates to a constant-temperature curing furnace. Background Art

[0002] Curing refers to the production process of heating parts, resin curing and drying adopted in the electronics industry and other industries to enhance the stress of material combination. Usually, powder is applied to the surface of a workpiece, and the inside of the curing furnace is heated to a certain temperature to melt the powder, and the powder flows and cures on the surface of the workpiece, so as to form a firm coating on the surface of the workpiece. However, most of the heating devices of the curing furnace are at the bottom of the curing furnace, which may cause the temperature at the bottom of the workpiece to be higher than the temperatures at the side and top of the workpiece, resulting in uneven heating of each part of the workpiece and uneven melting of the powder.

[0003] In search of solutions to the above problems, it is found that in the currently disclosed prior art, such as a constant-temperature curing furnace proposed in the patent with the publication number CN220658205U, the heating rods are installed on both sides inside the curing furnace, and a hook is rotatably installed at the top of the curing furnace. By hanging the workpiece on the hook for rotational heating, the heat is evenly distributed to each surface of the workpiece.

[0004] However, after the powder on the surface of the workpiece melts and flows on the workpiece, during the rotation of the workpiece, the melted powder may be thrown off the surface of the workpiece, making it difficult for the powder to be evenly spread on the workpiece, and still resulting in uneven dispersion. Summary of the Utility Model
