Description

Technical Field

[0001] This application relates to the field of core winding production, and particularly to a feeding and cutting device and a core winding equipment. Background Art

[0002] In the production process of cores, the precise cutting and stable conveying of pole pieces are one of the key links to ensure the quality and performance of cores. With the rapid development of automated production technology, the traditional manual or semi-automatic cutting and conveying methods can no longer meet the production requirements of large scale and high efficiency. Currently, although there are automated pole piece cutting devices on the market, these devices often rely only on a single clamping structure to achieve the movement and positioning of pole pieces during the pole piece conveying stage, while ignoring the stability control of pole pieces during the conveying process.

[0003] Specifically, since pole piece materials usually have high flexibility and low rigidity, simply relying on the clamping structure to clamp and drag the pole piece at specific positions easily causes the part of the pole piece that is not directly clamped to bend during the conveying process and cannot enter the cutting device, or enters the cutting device with deviation, distortion or even folding. This will not only seriously affect the cutting accuracy and consistency, but may also damage the physical properties of the pole piece, such as generating defects like wrinkles, thereby affecting the overall performance and lifespan of the core.

Detailed description of the specific implementation

[0045] The following details the embodiments of the present application. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application and should not be construed as a limitation of the present application.

[0046] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0047] In addition, the terms "first" and "second" are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality" means two or more unless otherwise specifically defined.

[0048] In the present application, unless otherwise clearly specified and limited, the terms such as "mounted", "connected", "coupled", "fixed", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0049] In the present application, unless otherwise clearly specified and limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0050] During the production of the battery cell, the electrode sheet needs to be cut into a certain length and then wound. Specifically, generally, the electrode sheet of the electrode sheet is dragged to the cutting position through a clamping structure. Without a guiding structure, the electrode sheet cannot accurately enter the cutting position, and there may also be phenomena such as bending and wrinkling, which will affect the cutting of the electrode sheet and cannot make the cut surface of the electrode sheet meet the predetermined requirements.

[0051] Since both the cathode sheet and the anode sheet in the battery cell are strip-shaped, the cathode sheet and the anode sheet can be understood as wound tapes here.

[0052] This application provides a feeding and cutting device, including a first linear driving module 100, a clamping component 200, a guiding component 300 and a cutting component 400. Among them, the first linear driving module 100 has a moving end, the clamping component 200 is fixedly installed on the moving end, the clamping component 200 has a feeding port and a discharging port, the clamping component 200 is used for clamping the wound tape, the guiding component 300 is located at the discharging port position, the guiding component 300 is used for guiding the wound tape coming from the clamping component 200, the cutting component 400 is located in the downstream direction of the clamping component 200, and the cutting component 400 is used for cutting the wound tape coming from the clamping component 200.

[0053] Refer to Figure 1 As shown, the first linear driving module 100 can drive the clamping component 200 to move closer to or away from the cutting component 400. Here, it should be noted that the discharging port of the clamping component 200 is an opening facing the cutting component 400, and the feeding port of the clamping component 200 is an opening away from the cutting component 400. Specifically, the guiding component 300 is fixedly arranged at the discharging port position of the clamping component 200, that is, as long as the wound tape is taken out from the discharging port of the clamping component 200, it will surely pass through the guiding of the guiding component 300. Therefore, each wound tape entering the cutting component 400 will pass through the guiding of the guiding component 300 to prevent the occurrence of phenomena such as bending and wrinkling of the wound tape.

[0054] In this embodiment, the first linear driving module 100 is a component or structure capable of realizing linear motion. Specifically, it can be a motor screw module, a linear motor module, a motor synchronous belt module, a cylinder and other components capable of realizing linear driving. In actual use, it can be selected according to the actual situation, and no limitation is made here.

[0055] The clamping assembly 200 includes a mounting frame 210, a first sliding plate 230, a fixing plate 240, and a first linear driving member 270. The mounting frame 210 is fixedly installed on the mobile end. An avoidance groove 220 is formed on the mounting frame 210. The first sliding plate 230 is slidably installed on the mounting frame 210. A first clamping member 250 is rotatably installed on the first sliding plate 230. The fixing plate 240 is fixedly installed on the mounting frame 210. A second clamping member 260 is fixedly installed on the fixing plate 240. The first sliding plate 230 and the fixing plate 240 are located on both sides of the avoidance groove 220. An outlet for the coiled tape is formed between the first clamping member 250 and the second clamping member 260. The first linear driving member 270 is used to drive the first sliding plate 230 to move so that the first clamping member 250 approaches or moves away from the second clamping member 260.

[0056] Refer to Figure 2 and Figure 3 As shown, in this embodiment, the coiled tape from the upstream first passes through the avoidance groove 220 and enters the clamping area formed between the first clamping member 250 and the second clamping member 260, and then gradually enters the guiding member 300 for guiding. Next, the first linear driving member 270 is started to drive the first sliding plate 230 to move towards the fixing plate 240, thereby also causing the first clamping member 250 to move towards the second clamping member 260. As the first clamping member 250 moves, the gap between the first clamping member 250 and the second clamping member 260 becomes smaller and smaller until the coiled tape located between the two is clamped. Subsequently, the first linear driving module 100 drives the mounting frame 210 to move towards the cutting assembly 400. The coiled tape is transported and transferred to the cutting position of the cutting assembly 400 under the guiding of the guiding member 300 and the clamping of the first clamping member 250 and the second clamping member 260, and is cut by the cutting assembly 400, so that the coiled tape can be cut into a certain length to meet the winding requirement of the battery cell.

[0057] Further, the first linear driving member 270 is a component that realizes linear driving such as a cylinder or a hydraulic cylinder. In this embodiment, the first linear driving member 270 is selected as a cylinder. Moreover, both the first clamping member 250 and the second clamping member 260 are rollers, and the two rollers approach each other to clamp the coiled tape therebetween. Further, the first clamping member 250 and the second clamping member 260 can also be clamping blocks. In practice, they can be selected or designed according to needs.

[0058] It should be noted here that the inlet of the clamping assembly 200 is the inlet of the avoidance groove 220; then the outlet of the clamping assembly 200 is the outlet of the clamping space formed by the first clamping member 250 and the second clamping member 260.

[0059] A guiding roller 600 is installed on the moving end of the first linear driving module 100, and the guiding roller 600 is located at the feeding port position of the clamping assembly 200.

[0060] Refer to Figure 1 and Figure 2 As shown, in order to facilitate the incoming tape from the upstream to enter the avoidance groove 220, a guiding roller 600 is arranged at the entrance position of the avoidance groove 220. The guiding roller 600 guides the incoming tape from the upstream, enabling the tape to smoothly enter the avoidance groove 220.

[0061] The guiding member 300 includes a first guide plate 310 and a second guide plate 320. The first guide plate 310 and the second guide plate 320 are located at the discharging port position of the clamping assembly 200, and a guiding gap 330 for guiding the tape is defined between the first guide plate 310 and the second guide plate 320.

[0062] Refer to Figures 1 to 3 As shown, after passing through the clamping area formed by the first clamping member 250 and the second clamping member 260 and then entering the guiding gap 330. Further, the first guide plate 310 is fixedly installed on the lower surface of the first sliding plate 230, and the second guide plate 320 is fixedly installed on the lower surface of the fixed plate 240. That is to say, when the first sliding plate 230 moves towards the fixed plate 240, it will also drive the first guide plate 310 to gradually approach the second guide plate 320, even if the space of the guiding gap 330 formed between the first guide plate 310 and the second guide plate 320 gradually becomes smaller. Therefore, the tape can be restricted in the guiding gap 330 (without clamping the tape). When the avoidance groove 220 moves towards the cutting assembly 400, the tape located in the guiding gap 330 will also move. Since the space where the guiding gap 330 is located is relatively small, it can accurately enter the cutting position of the cutting assembly 400. After the tape is pulled to the position of the cutting assembly 400, then the first linear driving member 270 drives the first sliding plate 230 to move, so that the first clamping member 250 moves away from the second clamping member 260, releasing the clamping state of the tape.

[0063] In this embodiment, the length and width of the first guide plate 310 and the second guide plate 320 can be adaptively adjusted as needed, and moreover, the minimum gap of the guiding gap 330 formed by the first guide plate 310 and the second guide plate 320 can also be adjusted as needed, which is not limited here.

[0064] In some embodiments, the first linear driving member 270 can be a linear driving component such as a cylinder or an oil cylinder. In this embodiment, the first linear driving member 270 is a cylinder.

[0065] The cutting assembly 400 includes a second linear drive module 410, a lifting frame 420, a fixed knife 440, a moving knife 450, and a second linear drive member 460. The second linear drive module 410 has a drive end, the lifting frame 420 is fixedly installed on the drive end, an installation chamber 430 is provided inside the lifting frame 420, the fixed knife 440 is fixedly installed on the lifting frame 420, the moving knife 450 and the fixed knife 440 are located on both sides of the installation chamber 430, the second linear drive member 460 is fixedly installed on the lifting frame 420, and the second linear drive member 460 is used to drive the moving knife 450 to approach or move away from the fixed knife 440.

[0066] Refer to Figure 4 , Figure 5 and Figure 6 As shown in, the cutting assembly 400 mainly cuts the tape located between the fixed knife 440 and the moving knife 450 by approaching each other. Specifically, the second linear drive member 460 drives the moving knife 450 to move towards the fixed knife 440. After the moving knife 450 moves a certain distance, the tape located between the two is cut. The principle of the fixed knife 440 and the moving knife 450 approaching each other to cut the tape can refer to the principle of scissor cutting, which will not be elaborated in detail here.

[0067] In this embodiment, the second linear drive member 460 can drive the lifting frame 420 to move, and thus the positions of the fixed knife 440 and the moving knife 450 can be changed, and different positions of the tape can be cut.

[0068] In one embodiment, the second linear drive member 460 can be a motor screw linear module, a motor synchronous belt linear module, a linear motor module, a motor gear rack linear module, etc. Specifically, in this embodiment, the second linear drive member 460 selects a motor screw linear module. In practice, other modules can be selected according to different environments, and no specific limitation is made here.

[0069] A clamping structure 470 is provided in the installation chamber 430. The clamping structure 470 includes a second sliding plate 471 slidably installed in the installation chamber 430. The second sliding plate 471 is connected to the drive end. The moving knife 450 is fixedly installed on the second sliding plate 471. A third clamping member 472 is slidably installed on the end face of the second sliding plate 471 facing the fixed knife 440. An elastic member 473 is provided between the third clamping member 472 and the second sliding plate 471.

[0070] Refer to Figure 5 and Figure 6As shown in the figure, in order to prevent the tape from moving during cutting, the tape located between the fixed knife 440 and the moving knife 450 is clamped and fixed by the clamping structure 470, which facilitates cutting. Specifically, a third clamping member 472 capable of sliding toward the fixed knife 440 is provided on the second sliding plate 471, and an elastic member 473 is provided between the third clamping member 472 and the second sliding plate 471. In order to enable the cutting and clamping to be synchronized, the moving knife 450 is fixedly installed on the bottom surface of the clamping structure 470. When cutting, the second linear driving member 460 drives the second sliding plate 471 to move toward the fixed knife 440. At the same time, the moving knife 450 and the third clamping member 472 move synchronously toward the fixed knife 440. The third clamping member 472 first clamps the tape on the side of the fixed knife 440. As the movement continues, the elastic member 473 is stressed and contracts. Next, the cutting edges of the moving knife 450 and the fixed knife 440 cooperate to cut the tape.

[0071] In this embodiment, the elastic member 473 is a spring, specifically a compression spring.

[0072] A dust removal member 480 is installed on the second linear driving module 410. The dust removal member 480 includes a first suction member 481 and a second suction member 482. The first suction member 481 and the second suction member 482 are located on both sides of the installation chamber 430, and suction ports 483 are provided on both the first suction member 481 and the second suction member 482.

[0073] Refer to Figure 4 、 Figure 5 and Figure 7 As shown in the figure, since a certain amount of dust will be generated during the cutting of the tape, in order to prevent the dust from affecting the entire tape, the first suction member 481 and the second suction member 482 are provided at the cutting position, and suction ports 483 are provided on both the first suction member 481 and the second suction member 482. The first suction member 481 and the second suction member 482 are connected to an external negative pressure device, and the dust is sucked away through the suction ports 483 by negative pressure. Specifically, the first suction member 481 is installed on the lifting frame 420 on the same side as the moving knife 450, and the second suction member 482 is installed on the lifting frame 420 on the same side as the fixed knife 440, specifically at the position shown in Figure 4 the figure.

[0074] A guiding component 500 is provided at the feeding port position of the clamping component 200. The guiding component 500 is used to guide the tape entering the clamping component 200. The guiding component 500 includes a fixed rod 510, a rotating roller 520 is rotatably installed on the outer surface of the fixed rod 510, a connecting piece 530 is fixedly installed at one end of the fixed rod 510, and a guiding plate 540 is fixedly installed on the connecting piece 530. A feeding gap is formed between the guiding plate 540 and the rotating roller 520.

[0075] See also Figure 1 , Figure 8 , Figure 9 As shown, in order to enable the tape from upstream to smoothly enter the avoidance groove 220, a guide component 500 may be further provided in the entrance direction thereof, and the guide component 500 is used to realize the steering and guidance of the tape from upstream. Specifically, the tape is wound around the outer surface of the rotating roller 520, and the rotating roller 520 will rotate synchronously with the conveyance of the tape. In order to prevent the pole ear of the pole piece (tape) from folding, a guide plate 540 is provided to form a gap between it and the outer surface of the rotating roller 520 through which only the pole ear and the pole piece pass, so that the pole ear and the pole piece are closely attached to the outer surface of the rotating roller 520, which can prevent the pole ear from folding to a certain extent.

[0076] The connecting member 530 includes a fixing member 531 fixedly mounted on the end of the fixing rod 510, a connecting rod 532 arranged parallel to the rotating roller 520 is mounted on the fixing member 531, a mounting member 533 is fixedly mounted on the connecting rod 532, and the guide plate 540 is fixedly mounted on the side facing the rotating roller 520.

[0077] See also Figure 9 and Figure 10 As shown, firstly, a fixing member 531, a connecting rod 532 and a mounting member 533 are provided to provide a fixing point for the installation of the guide plate 540. Specifically, the connecting rod 532 is parallel to the axis of the rotating roller 520, and the length of the connecting rod 532 is greater than the connecting portion 541, so that the tape can be guided to a certain extent. A certain limiting space is formed between the connecting rod 532 and the rotating roller 520 to prevent the tape from detaching from the rotating roller 520.

[0078] In this embodiment, the guide plate 540 includes a connecting portion 541 and a warping portion 542. The connecting portion 541 is used to connect to the mounting member 533 and form a passing gap with the rotating roller 520. The warping portion 542 gradually warps away from the rotating roller 520, thereby increasing the entrance and facilitating the passage of the pole ear and the pole piece.
