Description

A heat-conducting graphite sheet waste removal device

technical field

The invention relates to the field of graphite sheet processing, in particular to a heat-conducting graphite sheet waste removal device.

Background technique

In the production line of thermally conductive graphite sheets, thermally conductive graphite sheets are generally attached to strips and pass through a processing area, and the initial width of the strips is generally wider in order to be applied to thermally conductive graphite sheets of different sizes, so After attaching the heat-conducting graphite sheet with a fixed model size, it is necessary to cut the strip strip to reduce its width for the subsequent processing of the assembly line. In the prior art, the cutting method of the strip material is generally by manual measurement and cutting, and its precision is extremely poor, which will greatly affect the subsequent processing precision. Some also use mechanical shearing, but the precision of mechanical shearing is not high, and it is easy to be bent or folded to cause blockage, which requires manual real-time monitoring.

In addition, on the production line of thermally conductive graphite sheets, thermally conductive graphite sheets are generally attached to strips of material and pass through a processing area, while thermally conductive graphite sheets on the production line are generally made from a whole piece of thermally conductive graphite through a shearing device. During the cutting process, due to the problem of shearing accuracy, there are some heat-conducting graphite sheets whose specifications and sizes do not meet the predetermined requirements, whether large or small, which affects the later production line processing. The thermally conductive graphite sheet whose size is larger than the predetermined size can be cut again to obtain the standard size, but the thermally conductive graphite sheet whose size is smaller than the predetermined size cannot be reused and is a waste.

Therefore, it is necessary to invent a heat-conducting graphite sheet waste removal device to solve the above problems.
