Description

Technical field [0001] The invention relates to a graphite double encapsulation production equipment. Background technique [0002] Thermally conductive graphite sheet, also known as thermally conductive graphite sheet, heat dissipation graphite sheet, graphite heat sink and so on. Thermally conductive graphite sheet is a new type of heat-conducting and heat-dissipating material, and its heat-conducting and heat-dissipating effect is very obvious. Now it has been widely used in rop, LCD TV, Notebook PC, UMPC, Flat Panel Display, MPU, Projector, Power Supply, LED, etc. electronic product. It is also one of the most popular mobile phone heat dissipation films. [0003] In the production line of thermally conductive graphite sheet, the thermally conductive graphite sheet is generally attached to a strip of material and passes through a processing area, and the initial width of the strip of material is generally wider, so that it can be applied to thermally conductive graphite sheets...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the cutting method of the strip strip is generally cut by manual measurement, and its accuracy is extremely poor, which will greatly affect the subsequent processing accuracy

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

Moreover, when the graphite material is cut to the size required by the customer, the graphite powder particles will fall off the edge, which will affect the product performance, cleanliness, etc.

In addition, graphite is easy to delaminate, and powder is prone to affect performance and high cleanliness defect rate affects the qualified rate of finished products
