Description

Technical Field

[0001] The utility model relates to the technical field of copper foil production, in particular to a tensile strength detection device for copper foil production. Background Art

[0002] Copper foil is a cathodic electrolytic material, commonly used in various industrial production. Copper foil must have sufficient tensile strength and elongation. If the strength is not enough, it will result in low quality of finished products and low production efficiency during production. Therefore, a tensile strength detection device is often used in copper foil production.

[0003] The existing Chinese patent publication number is: CN220019168U. A thermal conductive silicone sheet tensile strength detection device includes two movable plates, the other end of the connecting rope extends to the outside of one of the connecting blocks and is fixedly connected to the outside of the other connecting block, and a guide groove for the connecting rope to move is provided on the outside of one of the connecting blocks, which solves the problem that the detection device in the prior art cannot observe the stretched length of the thermal conductive silicone sheet. When the thermal conductive silicone sheet is tested for tensile strength, it is generally necessary to fix the thermal conductive silicone sheet first, and then stretch it after fixing, so as to facilitate the tensile test. In the process of stretching the thermal conductive silicone sheet, if the stretched length is not observed and recorded, it is impossible to clearly understand the limit length of the thermal conductive silicone sheet that can be stretched, and thus it is impossible to clearly understand the technical problem of the tensile limit length and tensile limit strength of the thermal conductive silicone sheet.

[0004] The above technical solution solves the problem that the detection device in the prior art cannot observe the stretched length of the thermally conductive silicone sheet. When the device performs tensile testing on the detected object, it can only detect the tensile stress of the object, but cannot test the tensile endurance of the object. The detected object cannot meet the actual application needs. When performing the test, only the tensile resistance of the object is tested for a moment. When the object is pulled continuously for a certain period of time, the object may be deformed. Utility Model Content
