Description

Technical Field

[0001] The present application relates to the field of battery cell production and manufacturing, and in particular to a diaphragm trimming device and production equipment. Background Art

[0002] In the dry film-forming process, after the membrane is formed, the edges are often irregular due to the ductility of the material. These irregular edges need to be precisely removed before the subsequent compounding with the current collector to ensure the overall quality and performance of the product. In current industrial practice, the cutter design generally adopts a non-contact cutting strategy, that is, the cutter trims the edge of the membrane at a position away from the roller surface. However, this operation method faces a significant challenge: the tension of the membrane itself is extremely low. Once it is separated from the support of the roller surface, its structural stability is greatly reduced and it is very easy to break, which not only affects production continuity and yield, but also increases material loss.

[0003] In addition, the width adjustment of the current trimming process mainly relies on manual operation, which is not only time-consuming and labor-intensive, but also difficult to ensure the stability and consistency of cutting accuracy, which in turn affects the dimensional accuracy and appearance quality of the final product.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0037] In this application, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components or interactions between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on specific circumstances.

When a first feature is "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.

[0039] After the diaphragm is formed, its edges are uneven due to its ductility. Therefore, these irregular edges need to be cut off to ensure the overall quality and performance of the product. The existing non-contact cutting method is usually adopted, but the tension of the diaphragm itself is low. Once it is separated from the support of the roller surface, it is easy to break, thereby affecting the continuity and yield of production. The present application installs a linear drive member 200 that can be raised and lowered on the mover of the linear module 100, and then connects the cutter 400 to the lifting end of the linear drive member 200 through the driven frame 300. Then, the cutter 400 can be directly controlled by the linear drive member 200 to contact the roller to cut the diaphragm located on the surface of the roller, thereby realizing the trimming function. Since the trimming is completed on the roller, that is, the diaphragm is supported by the roller to achieve trimming, so that the diaphragm has support force during the trimming process and is not easy to break.

[0040] An embodiment of the present application provides a diaphragm trimming device, which includes a linear module 100 , a linear drive member 200 , a driven frame 300 , a cutter 400 , a rotating arm 500 , and a scraper 600 .

[0041] The linear module 100 has at least one mover, and a follower 110 is fixedly mounted on each mover. The linear module 100 is used to drive the follower 110 to move along a first preset direction. The linear driving member 200 is fixedly mounted on the follower 110, and the driven frame 300 is fixedly mounted on the moving end of the driven frame 300. The linear driving member 200 is used to drive the driven frame 300 to move along a second preset direction. The cutter 400 is rotatably mounted on the driven frame 300, and the cutter 400 follows the driven frame 300 to move along the second preset direction. The rotating arm 500 is rotatably mounted on the follower 110, and the rotating arm 500 follows the driven member 110 to move along the first preset direction. A scraper 600 is fixedly mounted on the rotating arm 500.

[0042] by Figure 1 and Figure 2 As shown, the first preset direction mentioned above is the lateral movement, and the second preset direction is the up and down movement direction.

[0043] See Figure 1 and Figure 2 As shown, the linear module 100 has two movers, each of which is equipped with a follower 110, that is, the linear module 100 can move the two followers 110, thereby changing the distance between the two followers 110, and then changing the distance between the two cutters 400, and can perform edge trimming on diaphragms of different widths. In addition, the linear module 100 can be controlled by a corresponding controller to achieve automatic adjustment. Compared with the existing manual adjustment method, the efficiency and accuracy are greatly improved.

[0044] For example, the linear module 100 may be a motor screw linear module, a gear rack linear module, etc., which is not limited here.

[0045] In one embodiment, a roller (not shown) is provided on the side of the two cutters 400 away from the linear drive member 200, and a diaphragm passes through the surface of the roller, and the diaphragm contacts the outer surface of the roller. When it is necessary to cut the edge of the diaphragm, the linear module 100 is first used to adjust the distance between the two cutters 400 so that the two cutters 400 are moved to a preset position. Next, the linear drive member 200 drives the cutter 400 installed on the driven frame 300 to move toward the diaphragm on the surface of the roller until the cutter 400 contacts the diaphragm and applies a certain pressure to cut the edge of the diaphragm, thereby completing the edge trimming.

[0046] Please continue reading Figure 1 and Figure 2 As shown, after the edge of the diaphragm is cut, in order to prevent the cut diaphragm from affecting the diaphragm passing through the surface of the roller, the rotating arm 500 rotates so that the scraper 600 contacts the surface of the roller to scrape off the cut diaphragm, thereby reducing the impact of the cut diaphragm on other diaphragms.

[0047] Illustratively, the linear drive member 200 is a cylinder or other structures or components that can achieve linear drive while meeting precision requirements.

[0048] Furthermore, in order to prevent the cutter 400 from damaging the surface of the roller due to downward pressure, the material selected for the cutter 400 can be selected according to the hardness of the roller. For example, the cutter 400 can be made of Teflon, PEEK polyetheretherketone, etc. with lower hardness. The cutter 400 is in the shape of a disc, and the outer peripheral surface of the cutter 400 is used to cut the diaphragm.

[0049] The diaphragm trimming device further includes a mounting frame 120 , which is used to mount the linear module 100 . The mounting frame 120 includes a connecting plate 121 , on which the follower 110 is fixedly mounted. Support seats 122 are mounted at both ends of the connecting plate 121 .

[0050] Please continue reading Figure 1 and Figure 2 As shown, in order to enable the linear module 100 to be installed and fixed, the installation conditions of the linear module 100 are met through the mounting frame 120. Specifically, the linear module 100 is fixedly mounted on the bottom surface of the connecting plate 121, and then the support seats 122 are installed on both sides of the connecting plate 121 to achieve support. The installation and fixation of the linear module 100 is achieved through the cooperation of the connecting plate 121 and the support seats 122.

[0051] The driven frame 300 includes a mounting plate 310 , a guide rod 320 , a fixing seat 330 and an elastic member 340 .

[0052] See also Figure 3 As shown, the mounting plate 310 is fixedly connected to the movable end of the linear drive member 200, and at least one guide rod 320 is slidably installed on the fixing seat 330 of the mounting plate 310 along a second preset direction. The fixing seat 330 is fixedly installed on the end of the guide rod 320 away from the mounting plate 310, and the elastic member 340 is arranged between the mounting plate 310 and the fixing seat 330.

[0053] In one embodiment, in order to enable the cutter 400 to apply a downward pressure to the surface of the roller, the elastic member 340 is compressed to cause the fixed seat 330 to drive the cutter 400 to move toward the roller and contact it to achieve cutting of the membrane, and the disc-shaped cutter 400 will be driven to rotate while the roller rotates.

[0054] Please continue reading Figure 3As shown, when it is necessary to trim the diaphragm, the linear drive member 200 is first used to drive the mounting plate 310 to move toward the roller, thereby also moving the fixing seat 330 and the cutter 400; when the cutter 400 contacts the diaphragm on the roller surface, as the linear drive member 200 continues to drive the driven frame 300 and the cutter 400 to move toward the roller, the elastic member 340 is compressed, and the fixing seat 330 moves toward the mounting plate 310 under the guidance of the guide rod 320. As the elastic member 340 contracts, the force of the cutter 400 on the diaphragm on the roller surface increases. When the pressure reaches a certain level, the diaphragm is cut and contacts the roller surface. At this time, the linear drive member 200 can stop driving the mounting plate 310 to move.

[0055] In one embodiment, in order to accurately control the force of the cutter 400 acting on the surface of the roller, a pressure sensor can be set at the connection between the mounting plate 310 and the linear drive member 200. The pressure sensor can monitor the force of the cutter 400 acting on the roller in real time, and find a range value between being able to cut the diaphragm and preventing damage to the roller.

[0056] Please continue reading Figure 2 As shown, during the movement of the fixed seat 330, in order to prevent the guide rod 320 from completely separating from the mounting plate 310, a limit plate (not marked in the figure) is provided on the top of the guide rod 320, thereby preventing the guide rod 320 from separating from the mounting plate 310 and limiting the maximum travel of the fixed seat 330.

[0057] The driven frame 300 also includes an elastic force adjustment component 350, which includes a connecting block 351 fixedly mounted on the fixing seat 330, an adjustment structure 352 installed on the connecting block 351, and the adjustment structure 352 is screwed to compress the elastic member 340, and a guide hole 353 is opened at the end of the connecting block 351 facing the mounting plate 310, a slide rod 354 is fixedly mounted on the adjustment structure 352, and the slide rod 354 is partially located in the guide hole 353, the elastic member 340 is sleeved on the connecting block 351 and the slide rod 354, one end of the elastic member 340 abuts against the fixing seat 330, and the end of the elastic member 340 away from the fixing seat 330 abuts against the adjustment structure 352.

[0058] See Figure 4 As shown, in the initial state, the fixing seat 330 will move away from the mounting plate 310 under the elastic force of the elastic member 340. At this time, if the cutter 400 contacts the diaphragm on the roller, it may not be able to cut due to insufficient pressure. If the elastic member 340 is compressed directly by the extension and contraction of the linear drive member 200, the operation will be complicated. At this time, the adjustment structure 352 can be screwed to make the slide rod 354 rebound or be compressed, and then the downward force of the fixing seat 330 to drive the cutter 400 can be adjusted, thereby adjusting the force of the cutter 400 acting on the roller.

[0059] Please continue reading Figure 4 As shown, when the adjustment structure 352 is screwed, the slide rod 354 will move away from or closer to the fixing seat 330. In order to make the elastic member 340 compress or rebound more smoothly and prevent the elastic member 340 from tilting, the slide rod 354 is slidably connected to the guide hole 353 of the connecting block 351.

[0060] Exemplarily, the slide rod 354 is a compression spring, which is sleeved between the guide hole 353 and the slide rod 354 .

[0061] The adjustment structure 352 includes a mounting hole 3521 opened on the mounting plate 310 and passing through it. A screw 3522 is installed in the mounting hole 3521. The screw 3522 is partially located in the mounting hole 3521. A baffle 3523 is fixedly provided at the end of the screw 3522 facing the fixing seat 330, and the elastic member 340 abuts against the baffle 3523.

[0062] See Figure 4 As shown, the screwing member 3522 is a cylinder with external threads, and the mounting hole 3521 is a threaded hole, that is, the screwing member 3522 and the mounting hole 3521 are threadedly connected, and a baffle 3523 is set at the end of the screwing member 3522 facing the fixing seat 330, and the end of the elastic member 340 abuts against the baffle 3523.

[0063] It can be understood that when the screwing member 3522 is screwed, under the action of the thread, the screwing member 3522 will move toward or away from the fixing seat 330, so that the baffle 3523 will also move toward or away from the fixing seat 330 together with the baffle 3523, thereby enabling the elastic member 340 to be compressed or rebounded.

[0064] Please continue reading Figure 4 As shown, in order to facilitate the screwing of the screwing member 3522 , a force-bearing member 355 is provided at the end of the screwing member 3522 facing away from the fixing seat 330 .

[0065] For example, the force-bearing member 355 may be a straight-line boss or a cylinder with a rough outer surface, so that the force-bearing member 3522 can be screwed by a human hand.

[0066] The diaphragm trimming device also includes a suction assembly 700, which includes a mounting base 710 fixedly connected to the rotating arm 500, and a scraper 600 is arranged at the end of the mounting base 710 away from the rotating arm 500. A negative pressure channel 720 is opened inside the mounting base 710, and the entrance of the negative pressure channel 720 is located at the position of the scraper 600. A suction pipe 730 is installed on the mounting base 710, and the suction pipe 730 is connected to the negative pressure channel 720.

[0067] See Figure 3 As shown, the entrance of the negative pressure channel 720 is located at the location of the scraper 600. The suction pipe 730 is connected to a negative pressure generating device, which continuously sucks the negative pressure channel 720 to form a negative pressure at the location of the scraper 600. Specifically, the diaphragm removed by the scraper 600 will enter the negative pressure channel 720 under the action of negative pressure and finally be extracted through the suction pipe 730.

[0068] Similarly, since the scraper 600 contacts the surface of the roller to scrape off the cut film, the material of the scraper 600 can be appropriately selected according to factors such as the hardness of the roller.

[0069] A first angle adjustment assembly 800 is provided on the follower 110 . The first angle adjustment assembly 800 includes a first connecting seat 810 installed on the follower 110 . A first screwing adjustment member 820 is installed on the first connecting seat 810 . The first screwing adjustment member 820 can be screwed toward the rotating arm 500 .

[0070] See Figure 3 As shown, when scraping off the membrane cut from the roller, in order to enable the scraper 600 to always be in contact with the surface of the roller, the first screw adjustment member 820 can be screwed so that its end abuts against the surface of the rotating arm 500. As the first screw adjustment member 820 continues to be screwed, the rotating arm 500 drives the scraper 600 to rotate toward the roller, so that the scraper 600 can always be in contact with the surface of the roller to achieve scraping. Moreover, since the end of the first screw adjustment member 820 is always in contact with the end of the rotating arm 500, the scraper 600 is always in contact with the surface of the roller through the rotating arm 500, thereby preventing the scraper 600 from separating from the surface of the roller.

[0071] A second angle adjustment assembly 900 is provided on the driven frame 300 . The second angle adjustment assembly 900 includes a second connecting seat 910 installed on the driven frame 300 . A second screw adjustment member 920 is installed on the second connecting seat 910 . The second screw adjustment member 920 can be screwed toward the rotating arm 500 .

[0072] Please continue reading Figure 3As shown, in this embodiment, the second connecting seat 910 is fixedly mounted on the mounting plate 310, that is, at this time, the second connecting seat 910 moves up and down along with the mounting plate 310; specifically, when there is no need to scrape off the diaphragm removed from the surface of the roller, the first screw adjustment member 820 can be rotated in the opposite direction to release the force acting on the rotating arm 500 and provide space for the rotating arm 500 to rotate and swing, and then the mounting plate 310 driven by the linear drive member 200 moves upward, at which time the second connecting seat 910 and the second screw adjustment member 920 will move upward along with the mounting plate 310, and then the second screw adjustment member 820 will move upward along with the mounting plate 310, and then the second screw adjustment member 820 will move upward along with the mounting plate 310. The end of the screw adjustment member 920 will contact the surface of the rotating arm 500. As the linear drive member 200 continues to drive the mounting plate 310 to move upward, the end of the second screw adjustment member 920 drives the rotating arm 500 to rotate away from the roller, thereby causing the scraper 600 to separate from the roller surface. Furthermore, in order to completely separate the scraper 600 from the roller, the second screw adjustment member 920 can be screwed to move its end toward the rotating arm 500, driving the rotating arm 500 to move away from the roller, so that the scraper 600 separates from the roller, preventing the scraper 600 from damaging the roller surface when not in use.
