[0002] In some die-cutting processes, the product is composed of a first component and a second component, and multiple products need to be arranged at intervals.

[0024] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention.

[0025] The embodiment of the present invention provides a die cutting method, please refer to Figure 1 , Figure 1 Schematic diagram of a die-cutting method according to an embodiment of the present invention. The die-cutting method includes: In step S100 , a first bottom film 50 is provided, and the first bottom film 50 is transported along a first direction at a first speed.

[0026] For details, please refer to Figure 2 , Figure 2 1 is a schematic diagram of a state in which the first component 10 is placed on the first base film 50 according to an embodiment of the present invention. The first direction is parallel to the X direction.

[0027] In step S200 , the first material strip is die-cut and laminated onto the first base film 50 , so that the first material strip forms a plurality of first components 10 on the first base film 50 that are spaced apart along a first direction.

[0028] For details, please refer to Figure 2 The first base film 50 is formed with a conveying surface, and the first components 10 are located on the conveying surface of the first base film 50. The first material strip moves along the X-direction to drive the first components 10 on the conveying surface of the first base film 50. It should be understood that the first material strip can be asynchronously die-cut to form a plurality of first components 10 arranged at intervals on the first base film 50. Alternatively, the first material strip can be die-cut and then manually arranged to form a plurality of first components 10 arranged at intervals on the first base film 50.

[0029] Step S300 : Compounding the second material strip 30 with the plurality of first components 10 .

[0030] For details, please refer to Figure 3 , Figure 3 1 is a schematic diagram of a state in which the second material strip 30 is combined with the first component 10 according to an embodiment of the present invention. The entire second material strip 30 is conveyed onto the first base film 50 so as to be combined with the plurality of first components 10 on the first base film 50.

[0031] In step S400 , the second material strip 30 is die-cut to form a plurality of second components 20 arranged along a first direction, so as to correspond one-to-one with the plurality of first components 10 to form a plurality of products 40 .

[0032] For details, please refer to Figure 5 and Figure 7 , Figure 5This is a schematic diagram of the arrangement of products 40 on the first base film 50 according to an embodiment of the present invention; Figure 7 FIG2 is a schematic diagram illustrating the process of transferring a product 40 from a first base film 50 to a second base film 60 according to an embodiment of the present invention. In this embodiment, a circular die-cutting method is used to cut the second material strip 30 into multiple segments, thereby forming the second material strip 30 composited with the first component 10. The multiple segments of the second material strip 30 correspond to each other to form multiple second components 20. A cutting line 70 is formed between adjacent second components 20, and the spacing between adjacent cutting lines 70 is equal to the spacing between adjacent first components 10. After the second material strip 30 is cut into multiple second components 20, the second components 20 can be combined with the first component 10 to form multiple products 40.

[0033] In step S500 , a second bottom film 60 is provided, and the second bottom film 60 is conveyed at a second speed greater than the first speed.

[0034] For details, please refer to Figure 6 and Figure 7 , Figure 6 Schematic diagram of an arrangement state of products 40 on the second base film 60 according to an embodiment of the present invention. The conveying direction of the second base film 60 and the conveying direction of the first base film 50 are in the same plane.

[0035] Step S600, please refer to Figure 7 , multiple products 40 on the first base film 50 are transferred to the second base film 60 so that the spacing between the products 40 on the second base film 60 is relatively increased.

[0036] Specifically, the conveying surface of the first base film 50 is flush with the conveying surface of the second base film 60. When the product 40 moves on the conveying surface of the first base film 50, it can move from the conveying surface of the first base film 50 to the conveying surface of the second base film 60, thereby achieving the transfer of the product 40 from the first base film 50 to the second base film 60. Multiple products 40 are arranged along a first direction on the first base film 50 and move at a first speed on the first base film 50. After one product 40 moves to the second base film 60, it moves at a second speed. Because the second speed is greater than the first speed, the distance between this product 40 and another product 40 arranged previously on the first base film 50 and not yet moved to the second base film 60 increases, thereby generating a spacing b between two adjacent products 40 on the second base film 60.

[0037] On the one hand, by conveying the product 40 to the second base film 60 at a first speed through the first base film 50, and conveying the product 40 at a second speed through the second base film 60, the interval between two adjacent products 40 can be increased, and there is no need to cut off part of the second material strip 30 as waste to form the interval between two adjacent products 40, thereby improving the utilization rate of materials. On the other hand, the first component 10 and the second component 20 form multiple products 40 on the first base film 50, and the multiple products 40 are spaced apart on the second base film 60, so that the production process of the product 40 can be completed on the same production line, thereby improving production efficiency.

[0038] In one embodiment of this embodiment, please refer to Figure 7 , the ratio of the first speed to the second speed is 0.32-0.48.

[0039] Specifically, the ratio of the first speed to the second speed can be 0.32, 0.36, 0.40, 0.44, and 0.48. It is understood that the spacing b between two adjacent products 40 on the second base film 60 can be adjusted by adjusting the ratio of the first speed to the second speed. If the ratio of the first speed to the second speed is too small, the spacing b between two adjacent products 40 on the second base film 60 will be too large. When the number of products 40 is the same, a larger spacing b between two adjacent products 40 will occupy more space than a smaller spacing b between two adjacent products 40, which is not conducive to the transportation and collection of the products 40. If the ratio of the first speed to the second speed is too large, the spacing b between two adjacent products 40 on the second base film 60 will be too small, resulting in the spacing b between the products 40 not meeting the requirements. Setting the ratio of the first speed to the second speed to 0.32, 0.36, 0.40, 0.44, and 0.48 is conducive to ensuring that the spacing b between the products 40 meets the requirements while reducing the space occupied by the products 40.

[0040] In one embodiment of this embodiment, the adsorption force of the second base film 60 on the product 40 is greater than the adsorption force of the first base film 50 on the product 40 .

[0041] Understandably, see Figure 7During the transfer of the product 40 from the conveying surface of the first base film 50 to the conveying surface of the second base film 60, part of the product 40 is located on the conveying surface of the first base film 50, while the remaining part of the product 40 is located on the conveying surface of the second base film 60. When the adsorption force of the first base film 50 on the product 40 is greater than the adsorption force of the second base film 60 on the product 40, during the transfer process, the product 40 is adsorbed by the first base film 50 and cannot move with the second base film 60 at the second speed. The part of the product 40 located on the second base film 60 slides and rubs against the second base film 60, generating vibration. The vibration of the product 40 pushes other products 40 on the first base film 50, changing the arrangement of the other products 40, resulting in uneven arrangement of the products 40. When the adsorption force of the first base film 50 on the products 40 is equal to the adsorption force of the second base film 60 on the products 40, during the transfer process, the products 40 will randomly follow either the first base film 50 or the second base film 60, randomly moving at the first speed or the second speed, making it difficult to control the spacing b between two adjacent products 40 on the second base film 60. Ensuring that the adsorption force of the second base film 60 on the products 40 is greater than that of the first base film 50 on the products 40 is conducive to arranging multiple products 40 in an orderly manner and ensuring that the spacing b meets the desired requirements.

[0042] In one embodiment of this embodiment, please refer to Figure 6 , the dimension a of the second component 20 in the first direction is 121.92 mm-182.88 mm.

[0043] Specifically, the dimension a of the second component 20 in the X-direction can be 121.92 mm, 137.16 mm, 152.40 mm, 167.64 mm, and 182.88 mm. It is understood that during the transfer of the product 40 from the conveying surface of the first base film 50 to the conveying surface of the second base film 60, the product 40 will experience sliding friction with the first and second base films 50, 60. The larger the dimension a of the product 40 in the first direction, the longer the product 40 is subject to sliding friction, resulting in a greater deviation from the desired position of the product 40. A larger dimension a of the second component 20 in the first direction also increases the dimension a of the product 40 in the first direction, leading to greater positional deviation of the product 40. During the process of separating two adjacent products 40 by a distance b, assuming the ratio of the first speed to the second speed is the same, the longer the relative motion time of the two adjacent products 40 increases, the greater the distance b between the two adjacent products 40. This relative motion time is positively correlated with the dimension a of the product 40 in the first direction. If the dimension a of the second component 20 in the first direction is too small, the dimension a of the product 40 in the first direction will be too small, which will require a larger ratio between the second speed and the first speed to ensure a sufficient spacing b between adjacent products 40. Setting the dimension a of the second component 20 in the first direction to 121.92 mm, 137.16 mm, 152.40 mm, 167.64 mm, and 182.88 mm not only helps reduce positional deviation of the product 40, but also helps ensure a sufficient spacing b between adjacent products 40 even when the ratio between the second speed and the first speed is small.

[0044] In an example of this embodiment, the interval between two adjacent second components 20 on the second base film 60 is 10.20 mm-15.32 mm.

[0045] For details, please refer to Figure 6 The interval between two adjacent second components 20 on the second base film 60 can be 10.20 mm, 11.48 mm, 12.76 mm, 14.04 mm and 15.32 mm.

[0046] It is understood that the spacing between two adjacent products 40 is the same as the spacing between two adjacent second components 20. If the spacing b between two adjacent products 40 on the second base film 60 is too large, when the number of products 40 is the same, a larger spacing b between two adjacent products 40 will occupy more space than a smaller spacing b between two adjacent products 40, which is not conducive to the transportation and collection of the products 40. If the spacing b between two adjacent products 40 on the second base film 60 is too small, the spacing b between the products 40 will not meet the requirements. The spacing between two adjacent second components 20 on the second base film 60 is 10.20mm, 11.48mm, 12.76mm, 14.04mm, and 15.32mm, which is conducive to ensuring that the spacing b between the products 40 meets the requirements while reducing the space occupied by the products 40.

[0047] In one embodiment of this embodiment, two first material strips and two second material strips 30 are provided to form two rows of first components 10 and second components 20 on the first base film 50, respectively. The two rows of first components 10 and the two rows of second components 20 are arranged at intervals along the second direction, and the second direction is perpendicular to the first direction. The two rows of first components 10 can be compounded with the two rows of second components 20 in a one-to-one correspondence to form two rows of products 40.

[0048] Specifically, the second direction is parallel to the direction Y. It is understandable that, with such an arrangement, two rows of products 40 can be produced simultaneously, which is beneficial to improving production efficiency.

[0049] In one embodiment of this embodiment, please refer to Figure 4 , Figure 4 Schematic diagram of a state in which two parts of a second material strip 30 are combined with a first component 10 according to an embodiment of the present invention. The second material strip 30 is combined with a plurality of first components 10, including: The second material strip 30 is symmetrically cut and stripped along the first direction to form two parts spaced apart along the second direction, and the two parts of the second material strip are combined with a plurality of first components 10 , where the second direction is perpendicular to the first direction.

[0050] Specifically, the second direction is parallel to the Y direction. In the Y direction, the sizes of the two parts of the second material strip 30 are respectively half of the size of the uncut second material strip 30. The two parts of the second material strip 30 are arranged at intervals in the Y direction in a circuitous manner.

[0051] It is understandable that some products 40 have two second components 20. With this arrangement, two rows of second components 20 can be formed after die-cutting the two portions of the second material strip 30, so that the die-cutting method can be used to produce products 40 with two second components 20.

[0052] In one embodiment of this embodiment, a second bottom film 60 is provided, and the second bottom film 60 is conveyed at a second speed greater than the first speed, comprising: A first deflection corrector is provided, which can push the product 40 on the second base film 60 in a direction parallel to the first direction to correct the position of the product 40 in the first direction.

[0053] Specifically, the first deflection corrector includes a visual component and a pusher. The visual component of the first deflection corrector can detect the position of the product 40 on the second base film 60 in the X direction. When the position of the product 40 in the X direction is not as expected, the pusher of the first deflection corrector can push the product 40 along the X direction to correct the position of the product 40 in the X direction.

[0054] Understandably, see Figure 7 When the product 40 is not completely transferred to the second base film 60, the portion of the product 40 located on the first base film 50 will slide and rub against the first base film 50, causing the product 40 and the second base film 60 to move relative to each other along the X direction and causing position deviation of the product 40. By providing a first deviation corrector to correct the position deviation of the product 40 in the X direction, it is beneficial to ensure that the distance b between two adjacent products 40 meets the expectations.

[0055] In one embodiment of this embodiment, a second bottom film 60 is provided, and the second bottom film 60 is conveyed at a second speed greater than the first speed, comprising: A second deflection corrector is provided, which can push the product 40 on the second base film 60 to correct the position of the product 40 in a second direction, which is perpendicular to the first direction.

[0056] Understandably, see Figure 7 When the product 40 is not completely transferred to the second base film 60, the portion of the product 40 located on the first base film 50 will slide and rub against the first base film 50, so that the product 40 may have a position deviation in the Y direction on the second base film 60. By setting a second deviation corrector to correct the position deviation of the product 40 in the Y direction, it is beneficial to arrange multiple products 40 neatly.

[0057] Second, see Figure 7The embodiment of the present invention provides a die-cutting device, which includes a first conveying device, a first die-cutting compounding device, a second die-cutting compounding device, and a second conveying device. The first conveying device is used to provide a first base film 50, so that the first base film 50 is conveyed at a first speed along a first direction; the first die-cutting compounding device is used to die-cut a first material strip and compound it onto the first base film 50, so that the first material strip forms a plurality of first components 10 arranged along the first direction on the first base film 50; the second die-cutting compounding device is used to compound a second material strip 30 with the plurality of first components 10 and die-cut the second material strip 30, so that the second material strip 30 forms a plurality of second components 20 arranged along the first direction, and the plurality of products 40 are formed in a one-to-one correspondence with the plurality of first components 10; the second conveying device is used to provide a second base film 60, so that the second base film 60 is conveyed at a second speed greater than the first speed, and the first conveying device is used to transfer the plurality of products 40 on the first base film 50 to the second base film 60, so that the spacing b between the products 40 on the second base film 60 is relatively increased.

[0058] Specifically, the first conveying device includes a plurality of first material rollers 82 arranged at intervals along a first direction. The first material rollers 82 are rotatable about rotation axes perpendicular to the first direction. The first base film 50 passes over the plurality of first material rollers 82 to form a conveying surface extending along the first direction. The first die-cutting and laminating device includes a circular knife located on the conveying surface of the first base film 50. The circular knife is used to cut the first material strip on the first base film 50 and laminate it onto the first base film 50, thereby forming the first material strip into a plurality of first components 10 arranged at intervals on the first base film 50. The second die-cutting and laminating device includes a cutting knife 81 located on the conveying surface of the first base film 50. The cutting knife 81 is used to cut the second material strip 30 on the first base film 50 and form the second material strip 30 into a plurality of second components 20 arranged at intervals on the first base film 50. The second conveying device includes a plurality of second material rollers 83, which are arranged at intervals along the first direction. The second material rollers 83 can rotate around a rotation axis perpendicular to the first direction. The second bottom film 60 passes around the plurality of second material rollers 83 to form a conveying surface extending along the second direction. The product 40 on the conveying surface of the first bottom film 50 can move to the conveying surface of the second bottom film 60.

[0059] On the one hand, the first conveying device and the second conveying device can cooperate with each other to increase the distance b between two adjacent products 40, without having to cut off part of the second material strip 30 as waste to form a gap between two adjacent products 40, thereby improving the utilization rate of materials. On the other hand, the first die-cutting composite device and the second die-cutting composite device cooperate with each other to form multiple products 40 on the first conveying device with the first material strip and the second material strip 30. The second conveying device can increase the distance b between two adjacent products 40, thereby fully completing the production process of the product 40, thereby improving production efficiency.

[0060] While the embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to the embodiments described above. Various modifications may be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof may be combined with one another unless there is a conflict.
