Further, the one-die cutting machine is provided with cutter lines a and b matched with one-die cutting pattern; the die-cut level of knife line a from the top down include second auxiliary release film, cloth base double faced adhesive tape and first auxiliary release film in proper order, the die-cut level of knife line b from the top down include second auxiliary release film and cloth base double faced adhesive tape in proper order.
Further, the knife line b is used for die-cutting the cloth-based double-sided adhesive tape to form a cloth-based double-sided adhesive tape finished product and frame waste.
Further, the one-shot waste comprises the whole second auxiliary release film, edge waste outside the knife line a and frame waste.
Further, the two-punch die-cutting machine is provided with cutter lines c and d matched with the two-punch die-cutting pattern; the punching layers of the cutter lines c and d sequentially comprise a handle release film and a cloth-based double faced adhesive tape from top to bottom.
Further, the cutter line d is used for die-cutting the handle release film to form a handle release film finished product and second frame waste.
Further, the secondary waste comprises second frame waste, edge waste except the knife line c and an auxiliary protective film.
Further, the waste discharge mode of the auxiliary protective film specifically comprises the following steps: and attaching the waste discharging Mylar under the auxiliary protective film, then rolling, and discharging the waste discharging Mylar and the auxiliary protective film together.
Further, the contour surrounded by the knife line b is smaller than the contour surrounded by the knife line d.
The die-cut piece of the conductive adhesive containing the cloth base, which is prepared by the method, comprises a finished product of the double-sided adhesive containing the cloth base and a finished product of the lifting handle release film.
The die-cutting piece also comprises an auxiliary release film during rolling, and besides the handle part, the outline of the cloth-based double faced adhesive tape finished product is about 2-4 mm away from the outline of the handle release film finished product.
Compared with the prior art, the invention has the following advantages:
(1) In the invention, the contour of the cutter line b is slightly smaller than the contour surrounded by the cutter line d during processing, so that even if burrs appear during initial processing of the conductive adhesive containing cloth base, the burrs can be covered by the handle release film at the later stage and cannot be exposed;
(2) By adopting the technology of the invention, the problem that the machine cannot grasp is solved because the filaments are not exposed any more, thereby improving the product quality.

Detailed Description
The invention will now be described in detail with reference to the drawings and specific examples.
Examples
A method for preparing a cloth-based conductive adhesive die-cut piece, as shown in fig. 2, comprising the following steps:
(1) Bonding of the primary material tape: sequentially attaching a first auxiliary release film 2, a cloth-based double-sided adhesive tape 3 and a second auxiliary release film 4 to the auxiliary protective film 1 to form a primary material belt, as shown in fig. 2; the model of the cloth-based double faced adhesive tape 3 is 3M 9711S-200;
(2) A die cuts and discharges waste: feeding the primary material belt into a punching and die-cutting machine for punching, and discharging a waste punching material to form a semi-finished product of the die-cut piece; wherein, a punching die cutter is provided with cutter lines a and b matched with a punching die cutting pattern, as shown in figure 3; the die-cut level of knife line a from the top down includes second auxiliary release film 4, cloth-based double faced adhesive tape 3 and first auxiliary release film 2 in proper order, and the die-cut level of knife line b from the top down includes second auxiliary release film 4 and cloth-based double faced adhesive tape 3 in proper order, as shown in fig. 4. The knife line b is used for die-cutting the cloth-based double-sided adhesive tape 3 to form a cloth-based double-sided adhesive tape finished product 31 and a frame waste 32. The first punching waste comprises the whole second auxiliary release film 4, edge waste except the knife line a and frame waste 32;
(3) Bonding of secondary material belts: attaching a handle release film 5 to the cloth-based double faced adhesive tape 3 to form a secondary material belt;
(4) Cutting and discharging waste by a secondary die: and feeding the secondary material belt into a two-punch die-cutting machine for punching, and discharging the two-punch waste material to form a finished product of the conductive adhesive die-cut piece containing the cloth base. Wherein, the two-punch die-cutting machine is provided with cutter lines c and d matched with the two-punch die-cutting pattern, as shown in figure 5; the punching layers of the cutter lines c and d sequentially comprise a handle release film 5 and a cloth-based double-sided adhesive 3 from top to bottom, as shown in fig. 6. The handle release film 5 is die-cut by the cutter line d to form a handle release film finished product 51 and a second frame waste 52. The secondary waste includes the second frame waste 52, the edge waste other than the knife line c, and the auxiliary protection film 1. The waste discharge mode of the auxiliary protection film 1 is specifically as follows: attaching the waste discharging Mylar 6 under the auxiliary protective film 1, then rolling, and discharging the waste discharging Mylar 6 and the auxiliary protective film 1 together; the contour surrounded by the knife line b is smaller than the contour surrounded by the knife line d.
The die-cut piece finished product, as shown in fig. 1, comprises a cloth-based double faced adhesive tape finished product 31 and a handle release film finished product 51, and further comprises a first auxiliary release film 2 when in rolling, wherein the outline of the cloth-based double faced adhesive tape finished product 31 is about 2-4 mm away from the outline of the handle release film finished product 51 except for a handle part.
In this embodiment, the probability of the post chip mounter catching deviation is almost 0.
Comparative example
The difference from the embodiment is that in this comparative example, the outline of the handle release film 5 and the cloth-based double-sided adhesive 3 are die-cut simultaneously.
In the comparative example, as the handle release film 5 and the cloth-based double faced adhesive tape 3 are die-cut and formed at the same time, the finished product has exposed broken filaments, and the grabbing probability of a later-stage chip mounter is about 40%.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the invention in any way, and any person skilled in the art may make modifications or alterations to the equivalent embodiments using the technical disclosure described above. However, any simple modification, equivalent variation and variation of the above embodiments according to the technical substance of the present invention still fall within the protection scope of the technical solution of the present invention.
