[0002] Laser die-cutting equipment uses a non-contact cutting method, has low operating costs, is easy to maintain, has the ability to cut complex shapes, and is widely applicable.

[0003] However, laser die-cutting equipment generates smoke and dust after cutting. Dust particles left on the battery cells can reduce battery capacity, shorten lifespan, and affect overall performance.

[0004] Therefore, reducing the dust content inside the laser die-cutting cavity is a problem that needs to be solved. Utility Model Content

[0005] The purpose of this application is to provide a laser die-cutting device and a battery production equipment.

[0006] According to a first aspect of the embodiments of this application, a laser die-cutting apparatus is provided, comprising:

Detailed Implementation

[0033] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present application.

[0034] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the scope of this application and its application or use.

[0035] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0036] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0038] First, it should be noted that the height direction, width direction, and thickness direction mentioned in the embodiments of this application are referred to in the appendix. Figure 1 , Figure 2 The marked directions. Among them, the axes in the height direction, width direction, and thickness direction intersect each other.

[0039] like Figures 1-4As shown, according to a first aspect of the embodiments of this application, a laser die-cutting apparatus is provided, including a cavity 1, a return air module 8, and a laser module 2; the cavity 1 forms an accommodating space 11 inside, and an air outlet 12 is provided at the bottom 13 of the cavity 1, the air outlet 12 communicating with the accommodating space 11; the return air module 8 is disposed outside the cavity 1, and the return air module 8 is communicating with the air outlet 12; the laser module 2 is disposed in the accommodating space 11, and a gap exists between the laser module 2 and the bottom 13 of the cavity 1.

[0040] like Figure 1 and Figure 2 As shown, the laser die-cutting device includes a cavity 1, a return air module 8, and a laser module 2. The cavity 1 has an internal accommodating space 11, and the laser module 2 is housed within this space. When the laser module 2 performs cutting, the cavity 1 prevents dust and debris generated during cutting from flying around. An air outlet 12 is located at the bottom 13 of the cavity 1, connecting the outside of the cavity 1 to the accommodating space 11. The return air module 8 is connected to the air outlet 12, thus communicating with the accommodating space 11. There is a gap between the laser module 2 and the bottom 13 of the cavity 1, meaning there is a certain space between them. This space facilitates maintenance and cleaning, and allows for easier operation of the bottom 13 area of ​​the cavity.

[0041] In the laser die-cutting device of this application, since dust will fall downwards under the action of gravity, an air outlet 12 is opened at the bottom 13 of the cavity 1. The air outlet 12 is connected to the return air module 8. The return air module 8 generates sufficient suction to suck out the dust that falls at the bottom 13 of the cavity 1 through the air outlet 12, thereby reducing the diffusion of dust in the air and its deposition on other parts of the laser die-cutting device or on the battery cells.

[0042] The return air module 8 can also be connected to a high-efficiency filtration system to ensure that dust is fully filtered and treated.

[0043] In one alternative implementation, such as Figure 2 and Figure 3As shown, in the height direction, the edge of the bottom 13 of the cavity 1 is higher than the middle position of the bottom 13 of the cavity 1, and the air outlet 12 is located at the middle position. Specifically, the edge of the bottom 13 of the cavity 1 is the perimeter of the cavity 1, and the perimeter of the bottom 13 of the cavity 1 is higher than the other areas of the bottom 13 of the cavity 1. That is to say, in the height direction, the perimeter of the bottom 13 of the cavity 1 is above the other areas of the bottom 13 of the cavity 1, and the middle position of the other areas is the lowest position in the height direction, and the air outlet 12 is located at the middle position. When dust falls on the bottom 13 of the cavity 1, since the middle position is the lowest, the dust will move towards the middle position. Since the air outlet 12 is located at the middle position, the dust can be more easily discharged from the air outlet 12. In this embodiment, the dust discharge efficiency can be improved.

[0044] In one alternative embodiment, the axis of the air outlet 12 intersects the axis of the height direction of the cavity 1; that is, the opening direction of the air outlet 12 is inclined relative to the height direction of the cavity 1, thereby improving the dust discharge efficiency.

[0045] In one alternative implementation, such as Figure 1 As shown, the laser die-cutting device also includes a baffle 3, which has multiple through holes 31. The baffle 3 is located at the bottom 13 of the cavity 1. The diameter of the through holes 31 is smaller than the diameter of the air outlet 12. Specifically, the baffle 3 has multiple through holes 31, the axis of which is in the same direction as the height. The through holes 31 are connected to the air outlet 12. Since the diameter of the through holes 31 is smaller than the diameter of the air outlet 12, the baffle 3 can filter out larger diameter particles to prevent them from falling into the air outlet 12 and clogging it.

[0046] In one optional embodiment, the laser die-cutting device further includes a lifting assembly located at the bottom 13 of the cavity 1, and the laser module 2 located on the lifting assembly; wherein the lifting assembly can adjust the distance between the laser module 2 and the bottom 13 of the cavity 1 in the height direction to adapt to different working scenarios or different material strips that need to be cut.

[0047] Specifically, the lifting component can be a drive component, which can drive the laser module 2 to move along the height direction; or, the lifting component can use height-adjustable feet or pads to gradually adjust the height of the bottom 13.

[0048] In one alternative embodiment, the height of the cavity 1 is less than the width of the cavity 1, and the thickness of the cavity 1 is less than the height of the cavity 1. When the height of the cavity 1 is small, the distribution of smoke and dust can be effectively concentrated, making them easier to be captured and treated by the return air device. Specifically, it can reduce the dead zone of airflow in the cavity 1, improve the dynamic efficiency of airflow, and help to remove pollutants in the air more efficiently.

[0049] In a preferred embodiment, the accommodating space 11 is provided with a flow guiding component to guide the airflow toward the air outlet 12, reduce dust accumulation, and prevent dust from falling onto the battery cells.

[0050] In one optional embodiment, the height of the cavity 1 is 800mm-900mm; the width of the cavity 1 is 850mm-1000mm; and the thickness of the cavity 1 is 650mm-800mm. Setting the dimensions of the cavity 1 within the above range effectively concentrates the distribution of smoke and dust. Specifically, it reduces dead zones in airflow within the cavity 1, improves the dynamic efficiency of airflow, and helps to remove pollutants from the air more efficiently. Preferably, the height of the cavity 1 is 850mm, the width of the cavity 1 is 920mm, and the thickness of the cavity 1 is 600mm.

[0051] In one optional embodiment, the distance between the laser module 2 and the bottom 13 of the cavity 1 is 5mm-20mm; wherein, the distance between the laser module 2 and the bottom 13 of the cavity 1 is set in the range of 5mm-20mm, which can increase the dust removal efficiency, wherein 10mm is the optimal distance between the laser module 2 and the bottom 13 of the cavity 1.

[0052] In one optional embodiment, the laser die-cutting device further includes a first adsorption module 6, a dust removal module 4, a waste collection module 5, and a second adsorption module 7. The dust removal module 4 is disposed in the accommodating space 11; the waste collection module 5 is disposed in the accommodating space 11, and the waste collection module 5 and the dust removal module 4 are spaced apart in the height direction; the first adsorption module 6 is disposed in the accommodating space 11; and the second adsorption module 7 is disposed in the accommodating space 11.

[0053] like Figure 1 , Figure 2 and Figure 3As shown, the laser die-cutting device also includes a dust removal module 4, a waste collection module 5, a first adsorption module 6, and a second adsorption module 7. The first adsorption module 6 provides negative pressure to adsorb the material strip and also adsorbs dust during laser module 2 cutting, thus playing a dust removal role. Since the material strip enters the cavity 1 vertically, it needs to be adsorbed onto the belt. The second adsorption module 7 provides negative pressure to adsorb the material strip. The dust removal module 4 is used to adsorb the dust sputtered after laser module 2 cutting. The waste collection module 5 is used to collect waste with a larger diameter.

[0054] In one specific embodiment, four schemes are set up, as shown in the table below:

[0055]

[0056] Where H is the height of cavity 1, A is the width of cavity 1, B is the thickness of cavity 1, and the distance between laser module 2 and bottom 13 of cavity 1 is h.

[0057] After simulation, as Figure 4 As shown in the table below:

[0058]

[0059] In summary, compared with the first, second and third schemes, the fourth scheme has the highest dust removal efficiency.

[0060] According to a second aspect of the embodiments of this application, a battery production apparatus is provided, including the laser die-cutting device described above.
