[0024] See also Figure 5 , Figure 5 Figure 2 is a schematic diagram of a conventional die-cutting process. In conventional technology, a third material strip 500 sequentially passes through a first die 600 and a second die 700, which die-cut the first material strip 300 and the second material strip 400, respectively, to form the first and second components arranged on the third material strip 500, thereby producing die-cut products. This production method requires a large number of molds, resulting in a large space requirement during the production process.
[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: Step S100, providing a cutting die 100, the cutting die 100 has a first cutter 10, a feed hole 30 and a second cutter 20 arranged in sequence along a first direction, the first cutter 10 and the second cutter 20 are located on the side of the cutting die 100 facing the die-cutting station 200, and the feed hole 30 connects the side of the cutting die 100 facing the die-cutting station 200 and the side of the cutting die 100 away from the die-cutting station 200.
[0026] Specifically, refer to Figures 2 to 4 , Figure 2 is Figure 1 the structure diagram of the die 100 in the die cutting method of the application; Figure 3 is Figure 2 the top view of the die 100 of the application; Figure 4 is Figure 3 the sectional view of the die 100 along the direction A-A of the application. The first direction is parallel to the X direction, the die cutting station 200, the first cutter 10 and the second cutter 20 are located on the same side of the die 100 along the Z direction, the first cutter 10 is located on the side opposite to the feeding hole 30 along the X direction, and the second cutter 20 is located on the side same as the feeding hole 30 along the X direction.
[0027] Step S200, providing a first material strip 300 and a second material strip 400, and conveying the first material strip 300 to the die cutting station 200 along the first direction, and conveying the second material strip 400 to the die cutting station 200 along the direction opposite to the first direction, and making the first material strip 300 and the second material strip 400 respectively pass into or out of the die 100 from the side of the die 100 away from the die cutting station 200 through the feeding hole 30.
[0028] Specifically, refer to Figures 3 to 4 , the part of the first material strip 300 located in the die cutting station 200 is conveyed along the positive direction of the X direction, and the part of the second material strip 400 located in the die cutting station 200 is conveyed along the negative direction of the X direction. In this embodiment, the first material strip 300 is conveyed to the die cutting station 200 from the side of the first cutter 10 away from the feeding hole 30, so as to pass through the side of the first cutter 10 away from the die 100 along the positive direction of the X direction, and extend into the feeding hole 30 from the side of the die 100 facing the die cutting station 200, so as to pass out of the feeding hole 30 from the side of the die 100 away from the die cutting station 200. The second material strip 400 can be conveyed to the die cutting station 200 from the side of the second cutter 20 away from the feeding hole 30, so as to pass through the side of the second cutter 20 away from the die 100 along the negative direction of the X direction, and extend into the feeding hole 30 from the side of the die 100 facing the die cutting station 200, so as to pass out of the feeding hole 30 from the side of the die 100 away from the die cutting station 200. The first material strip 300 and the second material strip 400 will form waste after being die cut, and the feeding hole 30 can be used to discharge the waste.
[0029] It should be understood that in some other embodiments, the feed hole 30 can also be used for feeding, and the first material strip 300 can be transported to the die-cutting station 200 from the side of the cutting die 100 away from the die-cutting station 200 through the feed hole 30, so as to pass through the side of the first cutter 10 away from the cutting die 100 in the opposite direction of the X direction, and leave the die-cutting station 200 from the side of the cutting die 100 in the opposite direction of the X direction, and the second material strip 400 can be transported to the die-cutting station 200 from the side of the cutting die 100 away from the die-cutting station 200 through the feed hole 30, so as to pass through the side of the second cutter 20 away from the cutting die 100 in the positive direction of the X direction, and leave the die-cutting station 200 from the side of the cutting die 100 in the positive direction of the X direction.
[0030] In step S300 , a third material tape 500 is provided. The third material tape 500 is located on a side of the first material tape 300 and the second material tape 400 that is away from the cutting die 100 .
[0031] For details, please refer to Figure 4 The third material strip 500 is located on the side of the first material strip 300 and the second material strip 400 away from the cutting die 100 along the Z direction.
[0032] In step S400, the first material strip 300 and the second material strip 400 located at the die-cutting station 200 are die-cut by the cutting die 100, so that the first cutter 10 die-cuts the first material strip 300 to form a first component, and composites the first component to the third material strip 500, and the second cutter 20 die-cuts the second material strip 400 to form a second component, and composites the second component to the third material strip 500.
[0033] For details, please refer to Figures 2 to 4 The first cutter 10 approaches the first material strip 300 from the side of the first material strip 300 facing away from the third material strip 500 to cut off a portion of the first material strip 300 and push it toward the third material strip 500, thereby forming a first component laminated on the third material strip 500. The second cutter 20 approaches the second material strip 400 from the side of the second material strip 400 facing away from the third material strip 500 to cut off a portion of the second material strip 400 and push it toward the third material strip 500, thereby forming a second component laminated on the third material strip 500.
[0034] In the die-cutting method of the present invention, on the one hand, the first cutter 10 and the second cutter 20 can respectively die-cut the first material tape 300 and the second material tape 400, so that the first component and the second component are arranged on the third material tape 500, without setting up multiple molds to complete the processing of the first component and the second component. On the other hand, the first material tape 300 and the second material tape 400 can be conveyed to the cutting die 100 from opposite sides of the cutting die 100, and leave the cutting die 100 from the feed hole 30, so that the first material tape 300 and the second material tape 400 can be conveyed along overlapping conveying directions, without the need to convey the first material tape 300 and the second material tape 400 in parallel, thereby reducing the space occupied by the production process.
[0035] In one embodiment of this embodiment, the cutting die 100 can perform reciprocating linear motion along a direction intersecting with the first direction. The cutting die 100 moves toward the first material strip 300 during the die-cutting cycle, and drives the first cutter 10 to die-cut the first material strip 300 by punching. The cutting die 100 moves away from the first material strip 300 during the reset cycle.
[0036] For details, please refer to Figures 2 to 4 The die cutter 100 performs reciprocating linear motion along the Z direction during alternating cycles of die cutting and reset. During the die cutting cycle, the die cutter 100 approaches the first material strip 300 along the Z direction to drive the first cutter 10 to die cut the first material strip 300. During the reset cycle, the die cutter 100 moves away from the first material strip 300 along the Z direction and resets to a preset position to prepare for the next cycle of die cutting.
[0037] It is understood that the die cutter 100 drives the first cutter 10 to die-cut the first material strip 300 by punching, which is beneficial to improving the forming accuracy of the first component. It is also understood that when the die cutter 100 drives the first cutter 10 to perform linear motion, it can simultaneously drive the second cutter 20 to punch the second material strip 400.
[0038] In one embodiment of this embodiment, a first material strip 300 and a second material strip 400 are provided, including: The first material tape 300 is intermittently fed toward the die-cutting station 200 along a first direction. The first material tape 300 is fed during a reset period and stops being fed during a die-cutting period.
[0039] Specifically, the first material strip 300 is fed through an asynchronous feeding mechanism. It is understandable that, during the multiple die-cutting movements of the die cutter 100, the interval feeding of the first material strip 300 can, on the one hand, enable the first cutter 10 to perform die-cutting at multiple positions on the first material strip 300 at intervals that meet expectations, thereby improving the utilization rate of the first material strip 300 and facilitating the adaptation to die-cutting requirements under different conditions. On the other hand, when the first cutter 10 cuts into the first material strip 300, the movement of the first material strip 300 may cause damage to the first material strip 300 and reduce the molding accuracy of the first component. Stopping the feeding of the first material strip 300 during the die-cutting cycle can help reduce the risk of damage to the first material strip 300 and improve the molding accuracy of the first component.
[0040] It should be understood that in some embodiments, while the first material strip 300 is intermittently fed to the die-cutting station 200 along the forward direction of the first direction, the second material strip 400 is intermittently fed to the die-cutting station 200 along the reverse direction of the first direction.
[0041] In an example of this embodiment, the cutting die 100 is provided with a positioning member 40 , and the positioning member 40 is used to extend into the hole on the third material tape 500 to position the third material tape 500 .
[0042] For details, please refer to Figures 2 to 4 The positioning member 40 is a pin extending in the Z direction. It is understood that when the positioning member 40 is inserted into the hole in the third material strip 500 , the third material strip 500 can be fixed relative to the cutting die 100 , which helps the cutting die 100 form the first and second components on the third material strip 500 in the desired positions.
[0043] In one embodiment of this implementation, a third material strip 500 is provided, comprising: The third material strip 500 is transported along a second direction, which is parallel to the first direction.
[0044] For details, please refer to Figures 2 to 4 , and the second direction is parallel to the X direction. It is understood that conveying the third material strip 500 in a direction parallel to the X direction, on the one hand, allows multiple first components and multiple second components to be sequentially laminated onto the third material strip 500 during multiple die-cutting operations of the first cutter 10 and the second cutter 20. Conveying the third material strip 500 in the second direction enables multiple first components to be arranged at intervals along the second direction on the third material strip 500, and multiple second components to be arranged at intervals along the second direction on the third material strip 500, which is beneficial to improving the applicability of the die-cutting method and, on the other hand, helps to reduce the space occupied in the Y direction during the production process.
[0045] In one embodiment of this embodiment, a limiting member 50 is provided on the cutting die 100, and the limiting member 50 is used to abut against the first material strip 300 and the second material strip 400 to limit the first material strip 300 and the second material strip 400 from moving relative to the cutting die 100 in a direction perpendicular to the first direction.
[0046] For details, please refer to Figures 2 to 4 A limiting groove 51 extending along the X direction is formed on the limiting member 50. Two limiting members 50 are provided, one limiting member 50 is located on the side of the first cutter 10 away from the feeding hole 30, and the other limiting member 50 is located on the side of the second cutter 20 away from the feeding hole 30.
[0047] It can be understood that the first material strip 300 can pass through the limiting groove 51 on the limiting member 50 located on the side of the first cutter 10 away from the feed hole 30 to be transported to the bottom side of the first cutter 10, and the second material strip 400 can pass through the limiting groove 51 on the limiting member 50 located on the side of the second cutter 20 away from the feed hole 30 to be transported to the bottom side of the second cutter 20. The groove wall of the limiting groove 51 can provide force along the Y direction to the first material strip 300 and the second material strip 400 to limit the movement of the first material strip 300 and the second material strip 400 along the Y direction relative to the cutting die 100, which is beneficial to improve the die-cutting accuracy.
[0048] In an example of this embodiment, on a plane perpendicular to the first direction, the projection of the first cutter 10 and the projection of the second cutter 20 are arranged at intervals.
[0049] For details, please refer to Figures 2 to 4 On a plane perpendicular to the X-direction, the projection of the first cutter 10 and the projection of the second cutter 20 are spaced apart along the Y-direction. This arrangement enables the first component and the second component to be spaced apart along the Y-direction on the third material strip 500, thereby reducing the risk of the first component and the second component overlapping on the third material strip 500.
[0050] In one embodiment of this embodiment, the cutting die 100 can make reciprocating linear motion along a direction intersecting with the first direction, and can drive the first cutter 10 to die-cut the first material strip 300 by punching, and the axial direction of the feeding hole 30 is parallel to the movement direction of the cutting die 100.
[0051] For details, please refer to Figures 2 to 4 The die cutter 100 can perform reciprocating linear motion along the Z direction, and the feed hole 30 is formed with an inner wall surface 32 parallel to the Z direction. It is understood that by setting the axis of the feed hole 30 parallel to the Z direction, when the first cutter 10 die-cuts the first material strip 300, the die cutter 100 moves along the Z direction, and the first material strip 300 and the second material strip 400 slide relative to the inner wall surface 32 along the Z direction, which helps reduce the risk of dust generated by the first material strip 300 and the second material strip 400 rubbing against the inner wall surface 32.
[0052] In one embodiment of this embodiment, a portion of the hole wall of the material hole 30 forms an arcuate surface 31, and the arcuate surface 31 extends in a direction perpendicular to the first direction, providing a first material strip 300 and a second material strip 400, including: The first material belt 300 at the feeding hole 30 abuts against the arc surface 31 and moves along the arc surface 31 . When the first material belt 300 moves along the arc surface 31 , the conveying direction of the first material belt 300 deflects relative to the first direction.
[0053] For details, please refer to Figures 2 to 4The axial direction of the curved surface 31 is parallel to the Y direction. It is understandable that part of the first material strip 300 needs to be conveyed along the X direction on the side of the first cutter 10 facing the die-cutting station 200, and the other part needs to be passed through the feed hole 30 and conveyed along the axial direction of the feed hole 30. By providing the curved surface 31, on the one hand, the first material strip 300 moves along the curved surface 31 when passing through the feed hole 30, so that the turning radius when the conveying direction of the first material strip 300 is turned to be parallel to the feed hole 30 is increased, thereby reducing the risk of the first material strip 300 being bent and unable to recover. On the other hand, the smooth surface of the curved surface 31 can reduce the risk of the first material strip 300 being scratched and generating dust.
[0054] In one embodiment of this embodiment, the cutting die 100 has a plurality of first cutting knives 10 and a plurality of second cutting knives 20, and the first material strip 300 and the second material strip 400 located at the die-cutting station 200 are die-cut by the cutting die 100, including: The first material strip 300 is die-cut simultaneously by multiple first cutters 10 to form multiple first components from the first material strip 300, and the multiple first components are compounded to the third material strip 500. The second material strip 400 is die-cut simultaneously by multiple second cutters 20 to form multiple second components from the second material strip 400, and the multiple second components are compounded to the third material strip 500.
[0055] For details, please refer to , four first cutters 10 are provided, and two second cutters 20 are provided. It can be understood that providing multiple first cutters 10 and multiple second cutters 20 enables the cutting die 100 to form multiple first components and multiple second components on the third material strip 500 in one die-cutting operation, which is conducive to improving die-cutting efficiency.
[0056] 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.
