Description

Technical Field

[0001] The utility model relates to the technical field of copper foil, in particular to a die-cutting device for copper foil assemblies. Background Art

[0002] Copper foil is a soft material with good conductive properties. By combining copper foils of different shapes, sizes and thicknesses to form copper foil assemblies, a variety of functions and applications can be achieved.

[0003] The existing Chinese patent with the authorization announcement number CN219380880U discloses a self-adhesive heat dissipation copper foil sleeve punching and die cutting device. It includes a horizontal plate, a connecting rod, an arc block, an air pump and a horizontal plate. The copper foil can be taken out by sliding the collection plate with a handle, so that the operator can quickly collect the self-adhesive heat dissipation copper foil.

[0004] The die-cutting device of the copper foil assembly is a device or tool used to perform die-cutting processing on the copper foil assembly. Die-cutting is a common processing method. The material is cut into the desired shape and size by applying force and cutting tools on the material. The die-cutting device is usually composed of a hydraulically driven cutting tool and a cutting table. The copper foil is cut through the contact between the tool and the cutting table. However, when the copper foil to be cut is long, the tool sticks to the copper foil during the contact with the copper foil, which makes it easy for the copper foil to move during the cutting process, causing deviations in the cutting position and burrs at the cut of the copper foil, affecting the processing quality of the copper foil product. Utility Model Content

When the extension length of the spring is reduced and the copper foil is initially fixed by the top pressure block, the positioning frame moves in the groove in the slide rail, and the distance between the pressure plate and the top pressure block is adjusted to adapt to the larger size of the copper foil. After the position is determined, the pressure plate is fixed to the top of the slide rail by bolts. When the tool holder is cutting, the copper foil is squeezed by the pressure plate arranged in a direction parallel to the main body of the machine base, so that the large-sized copper foil is not easy to deviate during cutting, thereby ensuring the quality of copper foil processing.

[0018] 2. The cut copper foil is separated by jetting outwards through the holes opened on the surface of the machine base through the jetting equipment body.
