[0002] A partially finished workpiece is composed of a plurality of sub-workpieces, and each sub-workpiece in the finished workpiece is spaced a certain distance from each other.

[0003] In the related art, when die-cutting such a finished workpiece, it is necessary to first die-cut each sub-workpiece separately, and then transfer each die-cut sub-workpiece to a base film so that each sub-workpiece is combined to form a finished workpiece.

[0004] However, since each sub-workpiece in the finished workpiece needs to be die-cut separately, and each sub-workpiece requires a separate bottom film for support during die-cutting, and a separate waste discharge film for waste discharge, the existing die-cutting process results in serious waste of auxiliary materials such as bottom film and waste discharge film during the die-cutting process to form the finished workpiece.

[0045] Reference below Figures 1 to 5 The die-cutting process of the first aspect of the present invention is described in detail.

[0046] refer to Figure 1 According to the die-cutting process of the first embodiment of the present invention, the die-cutting process includes but is not limited to the following steps:

[0047] Step S100, dividing the film material 100 into strips to form a plurality of strip-shaped member groups 200 distributed along a first direction, wherein the strip-shaped member groups 200 include a plurality of strip-shaped members 210 distributed along the first direction;

[0048] Step S200, spacing the strips 210 in the strip group 200 along the first direction so that any two adjacent strips 210 in the same strip group 200 are spaced a certain distance apart;

[0049] Step S300 , die-cut each strip 210 in the strip group 200 to form at least one sub-workpiece 301 on the strip 210 , and the multiple sub-workpieces 301 die-cut in the same strip group 200 together constitute a finished workpiece 300 .

[0050] Understandably, reference Figures 3 to 5 In the die-cutting process of the present invention, the film material 100 is firstly divided into strips to form a plurality of strip groups 200 distributed along a first direction, and the strip group 200 includes a plurality of strips 210 distributed along the first direction. Then, each strip 210 in the strip group 200 is spaced along the first direction so that any two adjacent strips 210 in the same strip group 200 are spaced a certain distance apart. Next, each strip 210 in the strip group 200 is die-cut to form at least one sub-workpiece 301 on the strip 210. The plurality of sub-workpieces 301 die-cut in the same strip group 200 together constitute a finished workpiece 300. In the die-cut workpiece of the present application, each strip 210 in the same strip group 200 can be separated first, and then each strip 210 in the same strip group 200 can be die-cut to form each sub-workpiece 301, so that each sub-workpiece 301 in the finished workpiece 300 can be die-cut in the same process.

[0051] It can be understood that in the die-cutting process of the present invention, the film material 100 is first divided into strips to form a plurality of strip groups 200, and each strip group 200 includes a plurality of strips 210 distributed along a first direction, and then the individual strips 210 in the same strip group 200 are spaced apart so that any two adjacent strips 210 are spaced a certain distance apart, so that each strip 210 can be die-cut from the same film material 100, thereby making the utilization rate of the film material 100 higher.

[0052] In some embodiments of the present invention, step S200 includes but is not limited to the following steps:

[0053] Step S210 , asynchronously transferring each strip 210 in the strip group 200 to the base film 400 , so that any two adjacent strips 210 are spaced a certain distance apart.

[0054] It is understandable that by asynchronously transferring each strip 210 on the strip group 200 to the base film 400, not only can any two adjacent strips 210 be spaced a certain distance apart, but the strips 210 carried on the base film 400 can also be easily die-cut.

[0055] In some embodiments of the present invention, step S200 also includes but is not limited to the following steps:

[0056] Step S220 , asynchronously transferring a plurality of strip-shaped member groups 200 to the bottom film 400 , so that any two adjacent strip-shaped member groups 200 are spaced a certain distance apart.

[0057] It can be understood that each strip 210 in the same group of strip groups 200 is die-cut by the same die-cutting roller, and any two adjacent groups of strip groups 200 are spaced a certain distance apart. Thus, during the movement of the base film 400, after the die-cutting roller rotates an integer number of circles, just one group of strip groups 200 can move to the die-cutting roller for die-cutting, thereby improving the accuracy of the die-cutting roller in die-cutting the strip groups 200.

[0058] In some embodiments of the present invention, reference Figure 2 In step S100, the following steps are included but not limited to:

[0059] Step S110, compounding the film material 100 onto the carrier film 500;

[0060] Step S120, dividing each sub-workpiece 301 of the finished workpiece 300 into a plurality of first sub-workpiece groups 310, wherein any two adjacent sub-workpieces 301 in the same first sub-workpiece group 310 at least partially overlap in the first direction;

[0061] Step S130 , layout the first sub-workpiece groups 310 in the finished workpiece 300 on the film material 100 , so that the first sub-workpiece groups 310 in the same finished workpiece 300 are arranged one-to-one on the strips 210 of the same strip group 200 .

[0062] For example, Figure 5 As shown, the finished workpiece 300 includes ten sub-workpieces 301, which are divided into five first sub-workpiece groups 310 spaced apart along a first direction, each first sub-workpiece group 310 includes two sub-workpieces 301 spaced apart along a second direction, and two sub-workpieces 301 in the same first sub-workpiece group 310 at least partially overlap in the first direction.

[0063] It is understandable that if two sub-workpieces 301 at least partially overlapping in the first direction are arranged in two strips 210 respectively, it will be difficult to separate the two strips 210. In the die-cutting process of the present invention, by arranging two sub-workpieces 301 at least partially overlapping in the first direction on the same strip 210, the film 100 can be smoothly separated into a plurality of strips 210 spaced apart along the first direction, and the difficulty of separating the strips 210 from the film 100 can be reduced.

[0064] In some embodiments of the present invention, step S300 includes but is not limited to the following steps:

[0065] Step S310 , die-cutting each sub-workpiece 301 in the corresponding first sub-workpiece group 310 on each strip-shaped member 210 .

[0066] It can be understood that by die-cutting each sub-workpiece 301 in the corresponding first sub-workpiece group 310 on each strip 210 , each sub-workpiece 301 die-cut on each strip 210 in the same strip group 200 together constitutes a finished workpiece 300 .

[0067] In some embodiments of the present invention, reference Figure 5 , each sub-workpiece 301 in the finished workpiece 300 is divided into two groups of second sub-workpiece groups 320 along the second direction, and each group of second sub-workpiece groups 320 includes multiple sub-workpieces 301 distributed along the first direction; the strip piece group 200 is die-cut by a die-cutting roller, and the die-cutting roller is provided with two groups of knife marks distributed along the length direction of the die-cutting roller, and the knife marks group is arranged in a one-to-one correspondence with the second sub-workpiece group 320, and the knife marks group includes multiple knife marks distributed along the circumference of the die-cutting roller, and each knife mark in the knife marks group is used to die-cut each sub-workpiece 301 in the corresponding second sub-workpiece group 320.

[0068] It can be understood that by arranging two knife-marking groups distributed along the axial direction of the die-cutting roller on the die-cutting roller, when the die-cutting roller is die-cutting the strip group 200, the two knife-marking groups can respectively die-cut two groups of second sub-workpiece groups 320 on the strip group 200, and then one die-cutting roller can complete the die-cutting of the finished workpiece 300 on the strip group 200.

[0069] In some embodiments of the present invention, reference Figure 1 The die-cutting process also includes but is not limited to the following steps:

[0070] Step S400 , rolling up the waste materials between the two groups of second sub-workpiece groups 320 in the finished workpiece 300 .

[0071] It can be understood that since the two groups of second sub-workpiece groups 320 are spaced apart along the second direction, after the die-cutting roller die-cuts the two groups of second sub-workpiece groups 320 from the strip group 200, there will be waste between the two groups of second sub-workpiece groups 320. By winding up the waste between the two groups of second sub-workpiece groups 320 in the finished workpiece 300, only the finished workpiece 300 will remain on the bottom film 400.

[0072] In some embodiments of the present invention, reference Figure 1 The die-cutting process also includes but is not limited to the following steps:

[0073] Step S500 , cutting the film material 100 to remove the surplus on two opposite sides of the film material 100 in the second direction.

[0074] It can be understood that since the two groups of second sub-workpiece groups 320 are distributed along the second direction, by removing the excess on the opposite sides of the film material 100 in the second direction, the subsequent die-cutting roller will only generate waste between the two groups of second sub-workpiece groups 320 after die-cutting each strip 210 in the strip group 200, thereby reducing the difficulty of waste discharge.

[0075] The die-cutting system provided in accordance with the second aspect of the embodiment of the present invention is used to implement the die-cutting process provided in accordance with the first aspect of the embodiment of the present invention.

[0076] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
