Description

石墨异步工艺Graphite Asynchronous Process

技术领域technical field

本发明涉及材料加工领域，尤其涉及一种石墨异步工艺。The invention relates to the field of material processing, in particular to a graphite asynchronous process.

背景技术Background technique

现在大多数的膜材产品都是通过模切成型的方式进行生产加工的。而在模切加工的过程中，模切步距参数往往是按照承载膜的最大尺寸来设定，这样一来模切出来的膜材产品尺寸也非常大。因此对于承载膜与产品的尺寸差距较大时，按照常规的模切成型工艺会非常浪费生产材料，大大加重了生产成本的负担。Most of the membrane products are now produced and processed by die-cutting. In the process of die-cutting, the die-cutting step parameter is often set according to the maximum size of the carrier film, so that the size of the die-cut film product is also very large. Therefore, when the size difference between the carrier film and the product is large, the conventional die-cutting molding process will waste production materials and greatly increase the burden of production costs.

After the three-layer graphite sheet and two layers of double-sided adhesive are laminated to form a composite layer, the composite layer is die-cut by asynchronous die-cutting, and the processed composite layer is transferred to Paste on the conductive cloth;

步骤4：第三次异步模切，采用异步模切方式对铜箔进行模切加工，并将加工后的铜箔转帖至复合层上；Step 4: For the third asynchronous die-cutting, the copper foil is die-cut by asynchronous die-cutting, and the processed copper foil is transferred to the composite layer;

步骤5：离型膜转帖，采用常规模切方式对离型膜进行模切加工，并将加工后的离型膜转帖至铜箔上，得到半成品；Step 5: Transfer the release film, die-cut the release film by conventional die-cutting, and transfer the processed release film to the copper foil to obtain a semi-finished product;

步骤6：模切手柄位避空位，采用常规模切方式进一步对离型膜进行模切加工，在离型膜上成型手柄位及其避空位；Step 6: Die-cut the handle position to avoid the void, and use the conventional die-cutting method to further die-cut the release film, and form the handle position and its avoidance position on the release film;

步骤7：模切产品区域外形，采用常规模切方式对复合成型的半成品进行模切加工，使半成品成型区域外形；Step 7: Die-cut the shape of the product area, and use the conventional die-cutting method to die-cut the compound-molded semi-finished product to make the shape of the semi-finished product forming area;

步骤8：模切承载膜外形，将轻膜复合于半成品上，再采用常规模切方式对承载膜进行模切加工，使承载膜外形成型，得到石墨膜材产品。Step 8: Die-cut the shape of the carrier film, compound the light film on the semi-finished product, and then die-cut the carrier film by conventional die-cutting to shape the shape of the carrier film to obtain graphite film products.
