Description

Technical Field

[0001] The utility model relates to the technical field related to copper foil processing, in particular to an oven protection device. Background Art

[0002] Copper foil is a cathodic electrolytic material, a very thin continuous metal foil. It is easy to adhere to the insulating layer, accept the printed protective layer, and form a circuit pattern after corrosion. Generally, after the copper foil undergoes a purification process, electrolyte will adhere to its surface and needs to be dried off.

[0003] For example, the Chinese utility model patent (CN211937718U) discloses a uniform drying mechanism of an oven for coating copper foil with glue, which comprises an oven body, a bearing 1 is fixedly connected to the bottom of the inner wall of the oven body, a connecting column is fixedly connected to the inner ring of the bearing 1, a cross plate is fixedly connected to the top of the connecting column, mesh plates are fixedly connected to both sides of the top of the cross plate, a transmission groove is provided at the center of the top of the front side of the oven body, and a slot is provided at the top of the front side of the oven body and on the left side of the transmission groove. The utility model solves the problem that the existing oven cannot bake and dry the copper foil uniformly by arranging an oven body, a bearing 1, a connecting column, a cross plate, a mesh plate, a transmission groove, a slot, a motor, a bevel gear 1, a bevel gear 2, a fixed column, a bearing 2 and a connecting plate. The uniform drying mechanism of the oven for coating copper foil with glue has the advantage of uniform drying, improves the practicality of the oven, and is convenient for users to use.

[0004] In summary, it can be seen that the following technical problems exist in the prior art: when drying copper foil in the existing copper foil drying box, the drying temperature inside is relatively high, and the electrolyte attached to the copper foil will be released into the air during drying and evaporation, causing certain harm to the surrounding staff. Therefore, when drying the copper foil, a protective cover needs to be placed on it to protect it. However, the copper foil occupies a large area, and the device for drying it is also large. When the box cover is opened, it can only stand upright on the drying box, which causes certain inconveniences in taking out the dried copper foil, and the use effect is not good. For this reason, the present application proposes an oven protection device to provide a new technical solution to solve the technical problems mentioned in the above patents. Utility Model Content
