TECHNICAL FIELD

[0001] The application relates to the technical field of copper foil conductive detection equipment, in particular to a copper foil conductive detection device and method in a high-temperature environment. BACKGROUND

[0002] As a kind of negative electrolytic material, copper foil is a thin and continuous metal foil deposited on the base layer of a circuit board, which serves as the conductor of the PCB. It is easy to adhere to the insulating layer and accept the printed protective layer, and forms a circuit pattern after corrosion.

[0003] Conductive performance is an important indicator of copper foil performance, so it must be detected when the copper foil is shipped. For copper foil conductive performance detection device, the prior art such as CN215116512U, CN219434947U and other schemes. The conductive detection device detects the copper foil in the high-temperature environment, which generally needs to manually contact the copper foil. Due to the conductive condition of the copper foil, manual operation may affect the safety of the copper foil conductive detection. During the detection process of the copper foil in the high-temperature environment, the sealing effect of the high-temperature environment is poor and is affected by the surrounding air, which may affect the detection effect of the copper foil in the high-temperature environment.

[0017] Preferably, a transparent observation window (13) is arranged on the side of the detection box (1).

[0018] Preferably, a conductive wire (9) is fixedly connected to the sealing cover plate (4).

[0019] Preferably, a temperature sensor (16) is fixedly installed on the detection box (1).

[0021] The method comprises the following steps:

[0022] S1, placing the copper foil to be detected on the bottom of the detection box;

[0023] S2, the first drive mechanism is activated to drive the sealing cover plate to descend until the conductive wire contacts the copper foil. At the same time, the fixing mechanism presses down and fixes the four corners of the copper foil to be tested.
