[0054] See also Figures 1 to 4 A material die-cutting device provided in an embodiment of the present application includes: a die-cutting component 10 and a material receiving component 20.

[0055] The die-cutting assembly 10, which serves as the structure through which the feed strip 1 passes and for die-cutting the strip 1, comprises a die-cutting base 11, a die-cutting element 12, and a die-cutting dust removal element 13. The die-cutting base 11 is provided with a feeding station 111 and a blanking station 112; the feeding station 111 is used for feeding the feed strip 1; the blanking station 112 is located below the feeding station 111. The die-cutting element 12 is disposed at the feeding station 111 and is used to die-cut the strip 1 into the material and the die-cut strip 2, which then falls into the blanking station 112. The die-cutting dust removal element 13 is disposed at the blanking station 112 and is capable of removing dust from the material within the blanking station 112.

[0056] After the die-cutting element 12 is die-cut, the cut portion of the strip 1 becomes the material, and the cut strip 1 becomes the die-cut strip 2. The die-cut strip 2 and the material are separated. The material can be, for example, an electrode, a diaphragm, etc. The die-cutting element 12 can be a cutter, a press, etc., specifically designed to cut the material from the strip 1. After die-cutting, the material falls into the unloading station 112, and the die-cut strip 2 continues to move.

[0057] The receiving assembly 20 is arranged behind the die-cutting seat 11 along the running direction of the die-cut material strip 2, and is used to collect the die-cut material strip 2. The receiving assembly 20 can process the collected die-cut material strip 2.

[0058] In this embodiment, since the material strip 2 is still in a strip shape after die-cutting, it can continue to be transported on the strip, which is convenient for its collection on the one hand, and on the other hand, the processing station can be moved back to avoid the particulate dust generated during the processing from affecting the material.

[0059] As an embodiment, the die-cutting piece 12 can be a pressing knife, which can be raised and lowered above the unloading station 112; the material belt 1 passes above the unloading station 112, and the top of the unloading station 112 and the threading station 111 can be in a through state; the die-cutting piece 12 is pressed down to press the material directly out of the material belt and make the material fall into the unloading station 112.

[0060] In one embodiment, see Figure 7 The top of the die-cut piece 12 can be connected to a lifting cylinder 14; the output end of the lifting cylinder 14 clamps the top of the die-cut piece 12 through the clamp 15, so that the lifting cylinder 14 can drive the die-cut piece 12 to move up and down.

[0061] As an embodiment, the mold cutting dust removal member 13 includes a suction pipe, which is connected to the blanking station 112. That is, in this embodiment, the mold cutting dust removal member 13 removes the dust in the blanking station 112 by suction.

[0062] In actual application, the material belt 1 is located above the unloading station 112. Except for one side where the suction pipe is set, the other sides of the unloading station 112 are all closed, so that a negative pressure chamber is formed in the unloading station 112, thereby ensuring the dust removal effect of the suction pipe on the unloading station 112.

[0063] For more specific examples, see Figure 5 The receiving assembly 20 includes a support roller 21, a feed roller 22, and a receiving box 23. The support roller 21 and the feed roller 22 are located at the entrance of the receiving box 23. The die-cut web 2 passes between the support roller 21 and the feed roller 22 and abuts against the support roller 21 and the feed roller 22. The support roller 21 and the feed roller 22 are used to clamp the die-cut web 2 and convey the die-cut web 2 into the receiving box 23.

[0064] The receiving assembly 20 may further include a plurality of auxiliary rollers 28. The auxiliary rollers 28 are used to support the die-cut material strip 2 to assist in the running of the die-cut material strip 2. The receiving box 23 may collect and process the die-cut material strip 2.

[0065] In one embodiment, a waste cutter 24 is provided on the receiving box 23. The waste cutter 24 is movably provided along a direction perpendicular to the running direction of the die-cut material belt 2, and can cut the die-cut material belt 2 entering the receiving box 23.

[0066] Optionally, a friction ring 25 is provided on the support roller 21 and / or the feed roller 22; the friction ring 25 can increase the friction force on the die-cut material strip 2 to ensure the stability of the strip running.

[0067] In one embodiment, the material receiving assembly 20 also includes: a material receiving seat 26 and a cylinder 27; the support roller 21 is fixed on the material receiving seat 26; the material receiving box 23 is fixed on the material receiving seat 26; the feed roller 22 is movably arranged on the material receiving seat 26; the cylinder 27 is fixed on the material receiving seat 26, and the output end of the cylinder 27 is connected to the feed roller 22.

[0068] The moving direction of the feed roller 22 can be a vertical direction. The cylinder 27 can drive the feed roller 22 to move and adjust the spacing between the feed roller 22 and the support roller 21, so that the material strip 2 passes between the two after die-cutting.

[0069] In one embodiment, a plurality of material adsorption holes 113 are provided on the unloading station 112. The material adsorption holes 113 can absorb the material tightly to achieve the fixation of the material.

[0070] It should be noted that, in actual applications, a conveying mechanism may be provided in the unloading station 112 , which can transfer the material from the unloading station 112 to the outside after the material is dust-removed.

[0071] As mentioned above, in order to improve the dust removal effect on the material, the unloading station 112 is in a negative pressure state during operation. For this reason, the other sides of the unloading station 112 can be set to an openable and closable structure; that is, during dust removal, the sides of the unloading station 112 are in a closed state; after dust removal, the sides of the unloading station 112 can be opened to allow the conveying mechanism to take out the material.

[0072] As an embodiment, the die-cutting seat 11 may include an upper layer and a lower layer; the upper layer is provided with a threading station 111; the lower layer is provided with a blanking station 112. The lower layer is provided with a handle 114. The lower layer is slidably connected to the upper layer, and the handle 114 cooperates to form a retractable structure for the lower layer. After dust removal, the staff can pull out the lower layer through the handle 114 to remove the material. It should be noted that in actual applications, taking the material as an electrode as an example, the material can be manually removed by the staff after being stacked to a certain thickness.

[0073] In one embodiment, the material die-cutting device further includes a cabinet 30; the cabinet 30 is an openable and closable structure; and the die-cutting assembly 10 is disposed within the cabinet 30. The die-cutting process of the material strip 1 described above can be performed within the cabinet 30. The cabinet 30 can form a closed space to prevent the impact of external dust on the material.

[0074] As a further improvement, the material die-cutting device also includes: a dust removal component 40 before die-cutting; a material belt inlet 31 is provided on the cabinet 30; the material belt 1 passes through the cabinet 30 from the material belt inlet 31; the dust removal component 40 before die-cutting is provided at the material belt inlet 31, which is used to remove dust from the material belt 1, ensuring the cleanliness of the material belt 1 entering the cabinet 30, and further reducing the impact of dust on the finished material.

[0075] As an embodiment, a translation platform 32 may be provided within the cabinet 30; the translation platform 32 is connected to the output end of a translation cylinder 33 and can be driven by the translation cylinder 33 to translate. The die-cutting assembly 10 may be placed on the translation platform 32, thereby enabling the position of the die-cutting assembly 10 within the cabinet 30 to be adjusted according to requirements such as the size of the strip 1 and the material size.

[0076] In actual application, the material receiving box 23 can be arranged outside the cabinet 30 and provided with a material feeding pipe extending into the cabinet 30; the above-mentioned support roller 21 and feed roller 22 are arranged at the entrance of the material feeding pipe.

[0077] In one embodiment, see Figure 2 and Figure 6 The material die-cutting device also includes: a belt detection component 50; the belt detection component 50 is arranged in the cabinet 30, and is used to perform visual inspection on the material belt 1.

[0078] In practical applications, the tape feed inspection assembly 50 may include a support frame 53, a light source 51, and a visual detector 52. The material strip 1 passes through the inspection station of the support frame 53. The visual detector 52, mounted on the support frame 53 and facing the inspection station, is used to detect whether the position of the material strip 1 meets the set requirements to ensure the die-cutting effect of the material strip 1. The visual detector 52 may be, for example, a camera. The light source 51, mounted on the support frame 53 and facing the inspection station, is used to provide supplementary light for the visual detector 52.
