Description

Technical Field

[0001] The present application relates to the field of battery production equipment, and specifically to a material strip cutting device and battery cell production equipment. Background Art

[0002] During battery production, the material strip (diaphragm or electrode) needs to be cut. During cutting, the fixed blade remains stationary while the movable blade moves along a first direction toward the fixed blade. Adjustable rigidity is required between the fixed and movable blades, i.e., adjustable contact force is required in a second direction to ensure cutting reliability. However, in the prior art, adjustable rigidity is implemented on the movable blade, meaning that the movable blade can move in both the first and second directions. This movement of the movable blade reduces the reliability of the material strip cutting process, resulting in, for example, inaccurate cutting positions and burrs. Utility Model Content

[0025] 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 arrangements of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0026] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present disclosure, its application, or uses.

[0027] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0028] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0029] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0030] In the following description, "connection" includes both a direct connection between the two and an indirect connection between the two through, for example, an adapter board, middleware, etc.

[0031] In the following description, "material strip" is only used to illustrate the working principle of the material strip cutting device and the battery cell production equipment, and should not be regarded as a part of the material strip cutting device and the battery cell winding equipment.

[0032] In the following description, the movable knife driving mechanism can be driven by various power sources such as a cylinder, a motor, etc.

[0033] In the following description, the first direction, the second direction, and the third direction intersect with each other and are three relative directions in a three-dimensional space.

[0034] like Figures 1 to 6 As shown, the strip cutting device in the embodiment of the present application includes: a tool holder 1, a movable tool holder 2, a movable knife 3, a fixed knife holder 4, a fixed knife 5, a movable knife drive mechanism 6, and a second direction adjustment assembly 7. The movable knife 3 is mounted on the movable tool holder 2 and is provided with a guide portion 301; the fixed knife 5 is mounted on the fixed knife holder 4; the movable knife drive mechanism 6 is mounted on the tool holder 1 and is used to drive the movable knife holder 2 toward or away from the fixed knife holder 4 in a first direction; the fixed knife holder 4 is connected to the tool holder 1 via the second direction adjustment assembly 7, wherein the second direction adjustment assembly 7 includes an elastic member 701, which elastically causes the fixed knife 5 to abut against the guide portion 301 of the movable knife 3. The first direction intersects the second direction.

[0035] More specifically, if Figure 1 As shown, the movable knife 3 is mounted on the movable knife seat 2, and the movable knife 3 and the movable knife seat 2 can be regarded as a whole. The movable knife 3 is provided with a guide portion 301, and the function of the guide portion 301 is to provide a guide for the relative movement between the movable knife 3 and the fixed knife 5 during the material strip cutting process. The fixed knife 5 is mounted on the fixed knife seat 4, and the fixed knife 5 and the fixed knife seat 4 can be regarded as a whole. The movable knife drive mechanism 6 is mounted on the knife holder 1. Figure 2When the material strip 10 shown is being cut, the fixed knife seat 4 and the fixed knife 5 remain stationary, and the movable knife driving mechanism 6 drives the movable knife seat 2 to approach the fixed knife seat 4 in the first direction, thereby making the movable knife 3 approach the fixed knife 5, and finally cuts the material strip 10. After the cutting is completed, the movable knife driving mechanism 6 drives the movable knife seat 2 to move away from the fixed knife seat 4 in the first direction, thereby making the movable knife 3 move away from the fixed knife 5. During the movement of the movable knife 3, the fixed knife 5 remains in contact with the movable knife 3. The fixed knife seat 4 is connected to the tool holder 1 through a second direction adjustment component 7, and the second direction adjustment component 7 includes an elastic member 701, and the elastic member 701 makes the fixed knife 5 elastically abut against the guide portion 301 of the movable knife 3. In one embodiment of the present application, the second direction adjustment component 7 adopts the following method: Figure 3 In other embodiments of the present application, a screw may be inserted through a through hole in the tool holder 1, then passed through the elastic member 701, and then passed through a through hole in the fixed blade holder 4, and finally secured with a nut. The screw primarily guides the fixed blade holder 4 to move relative to the tool holder 1 in the second direction, while the elastic member 701, by virtue of its elastic force, causes the fixed blade 5 on the fixed blade holder 4 to elastically abut against the guide portion 301 of the movable blade 3. In an embodiment of the present application, the fixed knife seat 4 is floatingly connected to the knife holder 1 through the second direction adjustment component 7, and the elastic member 701 makes the fixed knife 5 elastically abut the guide portion 301 of the movable knife 3. During the cutting process, the movable knife 3 can only move in the first direction, and the fixed knife 5 can only move in the second direction. That is to say, the movable knife 3 and the fixed knife 5 each have only one degree of freedom in one direction, and the movable knife 3 will not shake while moving in the first direction, thereby ensuring the reliability of the cutting of the material strip 10, the accurate cutting position, and the reduction of burrs. The fixed knife 5 elastically abuts the guide portion 301 of the movable knife 3, and ensures that there is a certain rigidity between the fixed knife 5 and the movable knife 3, and also avoids the collision between the movable knife 3 and the fixed knife 5, thereby improving the service life of the cutter.

[0036] like Figure 1 、 Figure 3 、 Figure 4 and Figure 6 As shown, in the embodiment of the present application, the second direction adjustment assembly 7 further includes a first adjustment rod 702. The first adjustment rod 702 connects the fixed blade seat 4 and the tool holder 1 and allows the fixed blade seat 4 to move relative to the tool holder 1 in the second direction. The elastic member 701 is disposed between the fixed blade seat 4 and the tool holder 1.

[0037] More specifically, the first adjustment rod 702 can also adopt a screw structure, serving as both a connector and a guide. For example, the first adjustment rod 702 passes through a through hole in the tool holder 1 and then engages with a threaded hole in the fixed blade seat 4. The rod is then tightened with a nut, allowing the first adjustment rod 702 to slide within the through hole in the tool holder 1. The elastic member 701 is sleeved onto the first adjustment rod 702 and positioned between the fixed blade seat 4 and the tool holder 1. Alternatively, the fixed blade seat 4 and the tool holder 1 may define a groove with opposing openings, with the elastic member 701 positioned within the groove. One end of the elastic member 701 abuts the fixed blade seat 4, while the other end abuts the tool holder 1, thereby ensuring elastic contact between the fixed blade 5 and the movable blade 3. By turning the first adjustment rod 702, the gap between the fixed blade seat 4 and the tool holder 1 can be adjusted. The size of this gap is related to the floating amount of the fixed blade seat 4 along the second direction. This structure is simple and easy to implement. When the fixed knife 5 elastically abuts against the guide portion 301 of the movable knife 3 , the first adjustment rod 702 itself is not affected by the elastic force of the elastic member 701 .

[0038] like Figure 3 As shown, in the embodiment of the present application, the second direction adjustment assembly 7 further includes a second adjustment rod 703 and an adjustment seat 704. The second adjustment rod 703 is threadedly engaged with the fixed blade seat 4, the second adjustment rod 703 abuts the adjustment seat 704, and one end of the elastic member 701 abuts the adjustment seat 704 and the other end abuts the tool holder 1.

[0039] More specifically, the second adjustment rod 703 can also be configured as a screw. The second adjustment rod 703 is threadedly engaged with a threaded hole in the fixed blade holder 4, extending partially beyond the fixed blade holder 4 and then abutting against the adjustment seat 704. One end of the elastic member 701 abuts the adjustment seat 704, while the other end abuts the tool holder 1. Consequently, the elastic member 701 is positioned between the tool holder 1 and the fixed blade holder 4. By turning the second adjustment rod 703, the distance between the adjustment seat 704 and the tool holder 1 can be adjusted, thereby adjusting the compression of the elastic member 701 and, consequently, the pressure exerted by the fixed blade 5 against the movable blade 3.

[0040] That is to say, in Figure 3 In the illustrated embodiment, the first adjusting rod 702 serves to adjust the gap between the fixed knife seat 4 and the knife holder 1 in the second direction, while the second adjusting rod 703 serves to adjust the pressing force between the fixed knife 5 and the movable knife 3 .

[0041] like Figure 6 As shown, in the embodiment of the present application, the tool holder 1 is provided with a guide groove 101 , and the fixed tool seat 4 is slidably engaged with the guide groove 101 along the second direction.

[0042] More specifically, the fixed knife seat 4 and the guide groove 101 slide in the second direction, which can limit the movement of the knife holder 1 in the first direction and the third direction, thereby preventing the fixed knife 5 from moving along the first direction and the third direction and affecting the cutting effect.

[0043] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, in the embodiment of the present application, the strip cutting device further includes a first direction adjustment component 8. The first direction adjustment component 8 is used to adjust the relative position between the fixed blade seat 4 and the blade holder 1 in a first direction.

[0044] More specifically, in one embodiment of the present application, the first direction adjustment component 8 can adopt two adjustment rods as shown in the figure. In other embodiments of the present application, only one adjustment rod can be adopted. For example, a screw rod is threaded with a nut, and then the screw rod passes through the threaded hole on the tool holder 1 and is finally screwed into the threaded hole of the fixed tool holder 4. In this way, by loosening the nut, adjusting the depth of the screw rod screwed into the tool holder 1, and then tightening the nut, the relative position of the fixed tool holder 4 relative to the tool holder 1 in the third direction can be adjusted.

[0045] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5 、 Figure 6 As shown, in the embodiment of the present application, the first direction adjustment assembly 8 includes a third adjustment rod 801 and a fourth adjustment rod 802. The third adjustment rod 801 is threadedly engaged with the tool holder 1 and abuts the fixed tool holder 4; the fourth adjustment rod 802 is threadedly engaged with the fixed tool holder 4 and abuts the side wall 102 of the guide groove 101.

[0046] More specifically, the third adjusting rod 801 and the fourth adjusting rod 802 can both adopt a screw structure. Figure 6 As shown, the guide groove 101 of the tool holder 1 has a side wall 102. Figure 5 As shown, after the third adjusting rod 801 is threadedly engaged with the tool holder 1, the end thereof abuts against the fixed tool holder 4, thereby limiting the fixed tool holder 4 from moving in the first direction. Figure 5 After the fourth adjusting rod 802 is threadedly engaged with the fixed blade seat 4, the end thereof abuts against the side wall 102 of the guide groove 101, thereby limiting the fixed blade seat 4 from moving in the first direction. Figure 5 In this way, by rotating the third adjusting rod 801 and the fourth adjusting rod 802, the depth of the third adjusting rod 801 and the fourth adjusting rod 802 into the guide groove 101 can be adjusted, thereby adjusting the position of the fixed blade seat 4 relative to the tool holder 1 in the first direction.

[0047] like Figure 1 and Figure 3As shown, in an embodiment of the present application, the material strip cutting device further includes a third direction adjustment component 9, which is used to adjust the relative position of the fixed knife seat 4 and the knife holder 1 in the third direction; the third direction intersects with the first direction and the second direction.

[0048] More specifically, in one embodiment of the present application, the third-direction adjustment assembly 9 utilizes two adjustment rods, as described in detail below. In other embodiments of the present application, a single adjustment rod in conjunction with a shim may also be employed. For example, in the third direction, the relative position of the stationary blade holder 4 and the tool holder 1 can be adjusted in the third direction by adding or reducing the number of shims at one end of the stationary blade holder 4 and adjusting the extension of the screw at the other end of the stationary blade holder 4.

[0049] like Figure 1 and Figure 3 As shown, in the embodiment of the present application, the third direction adjustment assembly 9 includes a fifth adjustment rod 901 and a sixth adjustment rod 902. The fifth adjustment rod 901 is threadedly engaged with the tool holder 1 and abuts one end of the fixed blade seat 4; the sixth adjustment rod 902 is threadedly engaged with the tool holder 1 and abuts the other end of the fixed blade seat 4.

[0050] More specifically, if Figure 3 As shown, the fifth adjusting rod 901 is threadedly engaged with the tool holder 1, and its end abuts one end of the fixed knife seat 4; the sixth adjusting rod 902 is threadedly engaged with the tool holder 1, and its end abuts the other end of the fixed knife seat 4. In this way, by rotating the fifth adjusting rod 901 and the sixth adjusting rod 902, the fixed knife seat 4 can be determined as follows: Figure 3 The position in the third direction shown is used to determine the position of the fixed blade seat 4 relative to the tool holder 1 in the third direction.

[0051] like Figure 3 、 Figure 6 As shown, in the embodiment of the present application, the tool holder 1 is provided with a guide groove 101, and the fixed tool holder 4 slides with the guide groove 101 along the second direction. The fixed tool holder 4 can move in the guide groove 101 along the first direction, the second direction, and the third direction.

[0052] More specifically, in the embodiment shown above, although the third adjustment rod 801 and the fourth adjustment rod 802 prevent the fixed blade holder 4 from directly contacting the guide groove 101 in the first direction, because the adjustment amount of the fixed blade holder 4 in the first direction is very small in actual operation, the fixed blade holder 4 is still considered to be able to slide with the guide groove 101. The ends of the fifth adjustment rod 901 and the sixth adjustment rod 902 also extend into the guide groove 101, so that the movement of the fixed blade holder 4 in the first, second, and third directions is restricted by the guide groove 101, thereby accurately positioning the fixed blade 5 and preventing the fixed blade 5 from colliding with the movable blade 3 due to adjustment misalignment or causing the cutting position of the material strip 10 to be incorrect. In addition, after the third adjustment rod 801, the fourth adjustment rod 802, the fifth adjustment rod 901, and the sixth adjustment rod 902 are adjusted into place, although the movement of the fixed blade 5 in the first and third directions is restricted by the first direction adjustment assembly 8 and the third direction adjustment assembly 9, it does not affect the movement of the fixed blade 5 in the second direction.

[0053] In the embodiment of the present application, the second direction adjustment component 7 and the first direction adjustment component 8 can be arranged in pairs, so as to ensure the flatness of the fixed knife 5 in all directions.

[0054] In the embodiment of the present application as described above, the first adjusting rod 702, the second adjusting rod 703, the third adjusting rod 801, the fourth adjusting rod 802, the fifth adjusting rod 901 and the sixth adjusting rod 902 all adopt a screw structure. In other embodiments of the present application, the first adjusting rod 702, the second adjusting rod 703, the third adjusting rod 801, the fourth adjusting rod 802, the fifth adjusting rod 901 and the sixth adjusting rod 902 can also be fully or partially equipped with a pin shaft or other structure to achieve connection, guidance and positioning.

[0055] The present application also provides a battery cell production device, comprising the strip cutting device described in any one of the above. The battery cell production device in the present application can achieve reliable strip cutting quality due to the use of the strip cutting device, thereby ensuring the quality of the battery cells.

[0056] The above embodiments focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.

[0057] Although some specific embodiments of the present application have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present application. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application.
