Description

Technical Field

[0001] This application relates to the field of electrode production, and more particularly to a diaphragm cutting device and electrode production equipment. Background Technology

[0002] In the dry rolling process of lithium battery electrodes, film cutting is a critical step that determines the dimensional accuracy of the electrode sheets. Currently, the industry generally uses fixed cutters, whose blades are in continuous contact and friction with the surface of high-speed rotating rolls. Long-term friction between the blade and the roll surface causes blade dulling and roll surface scratches, accelerates material fatigue of the cutter, and can even lead to chipping, significantly reducing equipment lifespan. Furthermore, during the cutting process, film debris accumulates in the cutting edge area, forming an irregular material layer that not only interferes with the accuracy of the cutting trajectory but also requires frequent shutdowns for cleaning. Manual debris removal not only increases maintenance costs but also severely disrupts continuous production, hindering overall efficiency. Utility Model Content

[0011] A scraper is fixedly installed on the negative pressure suction assembly, and the scraper is located at the suction port.

[0012] Furthermore, the guide rod and the lead screw are connected by a first transmission assembly. The first transmission assembly includes a first gear fixedly mounted on the guide rod and a second gear rotatably mounted on the lead screw. The first gear meshes with the second gear.

[0016] A transmission belt is wound around the circumference of the first pulley and the second pulley.

[0017] Furthermore, the driven member includes a mounting member, which includes a movable member and a rotating member.

[0019] Furthermore, the movable component has a guide hole with a first stepped surface. The movable component is provided with a second adjustment assembly, which includes a slide rod passing through the guide hole. The slide rod has a second stepped surface, and an elastic element is sleeved on the slide rod. One end of the elastic element abuts against the first stepped surface, and the other end of the elastic element away from the guide hole abuts against the second stepped surface. A mounting bracket is fixedly installed on the movable component, and a second micrometer head is fixedly installed on the mounting bracket. The driving end of the second micrometer head is connected to the slide rod in a transmission manner, and the slide rod is rotatably connected to the rotating component.

[0020] Furthermore, the negative pressure suction assembly includes a housing, the housing having a suction port on the side facing the cutter, the scraper being fixedly installed at the suction port, the housing being connected to a suction tube, and the housing being connected to the rotating component via a connecting assembly.

[0042] This application provides a diaphragm cutting device, which includes a mounting base 100, two driven members 200, a cutter 300, a negative pressure suction assembly 400, and a scraper 500.

[0043] In some specific embodiments, a guide rod 110 and a lead screw 120 are rotatably mounted on the mounting base 100. A rotary drive 130 is provided at the power input end of the guide rod 110. A driven member 200 is slidably mounted on the guide rod 110 and is drivenly connected to the lead screw 120. The lead screw 120 is used to drive the two driven members 200 to move closer to each other or away from each other. A cutter 300 is rotatably mounted on the driven member 200 and is drivenly connected to the guide rod 110. A negative pressure suction assembly 400 is fixedly mounted on the driven member 200 and is located on one side of the cutter 300. The negative pressure suction assembly 400 has a suction port 401. A scraper 500 is fixedly mounted on the negative pressure suction assembly 400 and is located at the suction port 401.

[0044] See Figures 1 to 4 As shown, in this embodiment, there are two mounting bases 100, which are spaced apart to form an installation space. The guide rod 110 and the lead screw 120 are rotatably mounted on the mounting base 100 along the height direction. Specifically, the lead screw 120 is a positive and negative thread lead screw.

[0045] In this embodiment, in order to prevent the cutter 300 from directly contacting the roller surface and causing damage to the roller surface, the cutter 300 can be kept at half the film thickness from the roller surface, so that the cutter 300 does not contact the roller surface, thereby preventing the cutter 300 from damaging the roller surface. It is understood that a scraper 500 is installed on the negative pressure suction assembly 400 at the position of the cutter 300. The scraper 500 contacts the roller surface to scrape the cut film off the roller surface, preventing the cut film from remaining on the roller surface.

[0046] It should be noted that, in order to prevent the scraper 500 from damaging the roller surface, the hardness of the scraper 500 should be less than that of the roller to prevent damage caused by contact between the scraper 500 and the roller surface.

[0047] In one embodiment, the two driven members 200 can be moved closer or further apart by rotating the lead screw 120, thereby adjusting the distance between the two cutters 300. Then, the distance between the cutter 300 and the roller surface can be adjusted so that the cutter 300 does not contact the roller surface. When cutting the film, the guide rod 110 can be rotated by rotating the drive member 130, which in turn drives the cutter 300 to rotate as well. The cutter 300 rotates to cut the film on the roller surface. In order to reduce the burrs generated during the cutting, the rotation direction of the cutter 300 is the same as the rotation direction of the roller. The film on the roller surface is cut during the process of the roller driving the film to be conveyed and the rotation drive member 130 driving the cutter 300 to rotate. At the same time, the scraper 500 scrapes the cut film off from the roller surface. The scraped film is sucked by the negative pressure suction assembly 400 to prevent the scraped film from accumulating on the roller surface.

[0048] In some specific embodiments, the guide rod 110 and the lead screw 120 are connected by a first transmission assembly 140. The first transmission assembly 140 includes a first gear 141 fixedly mounted on the guide rod 110 and a second gear 142 rotatably mounted on the lead screw 120. The first gear 141 meshes with the second gear 142. The second gear 142 has a shoulder, and at least one locking hole 143 is provided on the circumferential surface of the shoulder. A first screwing member 144 is installed in the locking hole 143.

[0049] Please see Figure 3 , Figure 4 as well as Figure 5 As shown, in order to automatically drive the lead screw 120 to rotate and adjust the distance between the two driven members 200, a first transmission assembly 140 is provided between the guide rod 110 and the lead screw 120 to achieve transmission. Specifically, when it is necessary to adjust the distance between the two driven members 200, the first screwing member 144 can be screwed in the locking hole 143, so that the end of the first screwing member 144 abuts against the lead screw 120, so that the second gear 142 and the lead screw 120 can rotate synchronously. At this time, under the meshing between the second gear 142 and the first gear 141, the... The rotational power of the guide rod 110 is transmitted to the lead screw 120, thereby driving the two driven members 200 to move closer or further apart, thus adjusting the distance between the two cutters 300. After the distance between the two cutters 300 is adjusted, the first screwing member 144 is unscrewed, releasing the state of the first screwing member 144 abutting against the circumference of the lead screw 120. At this time, the second gear 142 returns to the state of rotational connection with the lead screw 120. The guide rod 110 drives the second gear 142 to rotate through the first gear 141 without transmitting power to the lead screw 120.

[0050] In this embodiment, the first screwing component 144 can be a bolt, the locking hole 143 is a threaded hole, and the first screwing component 144 and the locking hole 143 are threaded together.

[0051] In some specific embodiments, the diaphragm cutting device further includes a second transmission assembly 600, which includes a first pulley 610, a second pulley 620, and a transmission belt 630. The first pulley 610 is slidably disposed on the guide rod 110 and rotates with the guide rod 110. The driven member 200 is rotatably connected to the guide rod 110. The second pulley 620 is fixedly installed on one side of the cutter 300. The transmission belt 630 is wrapped around the circumference of the first pulley 610 and the second pulley 620.

[0052] Please see Figure 3 , Figure 4 , Figure 6As shown, in this embodiment, the guide rod 110 is a splined guide rail, and the first pulley 610 mainly consists of a wheel body and a bushing. The bushing is slidably mounted on the guide rod 110, the wheel body is fixedly connected to the bushing, and the bushing is rotatably connected to the driven member 200. Specifically, the bushing is connected to the driven member 200 by a bearing. It should be noted that during the movement of the driven member 200, it drives the bushing to move circumferentially on the guide rod 110, thereby driving the wheel body to move as well. Furthermore, since the bushing and the guide rod 110 are slidably connected and the two are in transmission, that is, when the guide rod 110 rotates, it will drive the bushing to move, thereby driving the wheel body to rotate.

[0053] In this embodiment, the rotary drive 130 drives the guide rod 110 to rotate, which in turn drives the first pulley 610 to rotate. At the same time the first pulley 610 rotates, the second pulley 620 is driven to rotate through the transmission belt 630, thereby driving the cutter 300 to rotate and cut the film.

[0054] In some specific embodiments, the driven member 200 includes a mounting member 210, which includes a movable member 211 and a rotating member 212. The movable member 211 is slidably disposed with the guide rod 110 and is connected to the lead screw 120 for transmission. The rotating member 212 is rotatably mounted on the movable member 211. A cutter 300 and a negative pressure suction assembly 400 are rotatably mounted on the rotating member 212. The driven member 200 also includes a first adjustment assembly 220. The first adjustment assembly 220 has two abutment blocks 221 fixedly disposed on the rotating member 212. The abutment blocks 221 are symmetrically distributed about the rotation axis of the rotating member 212. The movable member 211 is also provided with two first microheads 222 corresponding to the abutment blocks 221.

[0055] Please see Figure 6 , Figure 7 as well as Figure 8 As shown, by rotating the rotating component 212 and the moving component 211, the rotation angle of the rotating component 212 is controlled by the first adjusting component 220, thereby facilitating the adjustment of the angle of the cutter 300. Specifically, during adjustment, the rotation angle of the rotating component 212 can be adjusted by extending the length of the two first micro heads 222, thereby adjusting the angle of the cutter 300 rotatably mounted on the rotating component 212. During debugging, it is ensured that the cutting direction of the cutter 300 is perpendicular to the roll surface.

[0056] In some specific embodiments, the movable component 211 has a guide hole 2110 with a first stepped surface. The movable component 211 is provided with a second adjustment component 230, which includes a slide rod 231 passing through the guide hole 2110. The slide rod 231 has a second stepped surface. An elastic element 232 is sleeved on the slide rod 231. One end of the elastic element 232 abuts against the first stepped surface, and the other end of the elastic element 232 away from the guide hole 2110 abuts against the second stepped surface. A mounting bracket 233 is fixedly installed on the movable component 211. A second micrometer head 234 is fixedly installed on the mounting bracket 233. The driving end of the second micrometer head 234 is connected to the slide rod 231. The slide rod 231 is rotatably connected to the rotating component 212.

[0057] Please see Figure 6 As shown, in order to adjust the distance between the cutter 300 and the roller surface, it is necessary to move the cutter 300, which in turn moves the rotating component 212. Specifically, a slide rod 231 is slidably installed in the guide hole 2110 of the moving component 211. The slide rod 231 passes through the guide hole 2110 and is rotatably connected to the rotating component 212. An elastic element 232 is sleeved on the slide rod 231, and the end of the elastic element 232 abuts against the stepped surface of the slide rod 231. An upward elastic force is applied to the slide bar 231. In order to adjust the height of the rotating part 212, a mounting bracket 233 is installed on the moving part 211. A second differential head 234 is installed on the mounting bracket 233 to drive the slide bar 231 to move in the guide hole 2110. The second differential head 234 drives the slide bar 231 to move, thereby moving the rotating part 212, thereby adjusting the distance between the cutter 300 and the roller surface, and thus adjusting the depth to which the cutter 300 cuts into the film.

[0058] In some specific embodiments, the negative pressure suction assembly 400 includes a housing 410, a suction port 401 is provided on the side of the housing 410 facing the cutter 300, a scraper 500 is fixedly installed at the suction port 401, a suction tube 420 is provided in connection with the housing 410, and the housing 410 and the rotating member 212 are connected by a connecting assembly 430.

[0059] Please see Figure 7 As shown, in order to prevent the cut film from accumulating on the roller surface, a housing 410 connected to a suction pipe 420 is provided at the position of the cutter 300, and the scraper 500 is installed at the suction port 401 of the housing 410. It can be understood that when the scraper 500 peels the film off the roller surface, the film is drawn into the interior through the suction port 401 by the suction action of the suction pipe 420, thereby removing the film.

[0060] The end of the suction tube 420 away from the housing 410 can be connected to a negative pressure generating device, thereby generating negative pressure at the suction port 401 to pull the diaphragm away.

[0061] In some specific embodiments, the connecting component 430 includes a first mounting block 431 and a second mounting block 432. The first mounting block 431 is fixedly mounted on the housing 410, and the second mounting block 432 is fixedly mounted on the rotating component 212. The first mounting block 431 is hinged to the second mounting block 432. The first mounting block 431 has a connecting hole 433. The second screwing component 434 passes through the connecting hole 433 and is connected to the mounting hole.

[0062] Please continue reading. Figure 7 As shown, the connecting hole 433 is an arc-shaped elongated hole. In order to adjust the position of the scraper 500 and make the scraper 500 contact the roller surface, the housing 410 can be hinged to the second mounting block 432. Then, the second screwing member 434 passes through the connecting hole 433 and is connected to the first mounting block 431. During the adjustment, the scraper 500 can be rotated by the housing 410 at a certain angle. After the scraper 500 reaches the predetermined position, the second screwing member 434 passes through the connecting hole 433 and is connected to the first mounting block 431, fixing the first mounting block 431 and the second mounting block 432 so that their positions remain unchanged, thus completing the position adjustment of the scraper 500.

[0063] In some specific embodiments, the diaphragm cutting device further includes a limiting component 700, which includes a sensor 720 and a sensing rod 730. The sensor 720 is fixedly mounted on a mounting plate 710 disposed on one of the mounting bases 100, and the sensing rod 730 is fixedly mounted on a follower 200 near the sensor 720.

[0064] Please see Figure 1 and Figure 2 As shown, when adjusting the distance between the two cutters 300, in order to prevent the driven member 200 from colliding with the mounting base 100, it is necessary to limit its maximum position. Specifically, a sensor 720 is installed on one of the mounting bases 100, and a sensing rod 730 is installed on the driven member 200. When the sensing rod 730 moves to the position of the sensor 720, it will be sensed. At this time, the stroke of the driven member 200 reaches its maximum, and the screw 120 should be stopped from rotating to prevent the driven member 200 from colliding with the mounting base 100.

[0065] For example, sensor 720 may be a photoelectric sensor or a proximity sensor, etc.

[0066] This application also provides an electrode production apparatus, which includes any of the above-described film cutting devices.
