Description

Technical Field

[0001] The utility model relates to the technical field of battery manufacturing equipment, in particular to a dust suction mechanism and a rolling device. Background Art

[0002] Lithium-ion power batteries have the characteristics of high working voltage, large specific energy, small volume, light weight, long cycle life, low self-discharge rate, no memory effect, and no pollution, and are favored by many power equipment manufacturers.

[0003] The production process of lithium batteries includes the following stages: pole piece production, battery cell production, and battery assembly. When producing the pole piece, the slurry is continuously and evenly coated on the surface of the foil and dried to form the pole piece. The prepared pole piece is compacted in a rolling device so that the active material is tightly combined with the foil and the thickness of the pole piece is more uniform.

[0004] The rolling device includes a pressure roller for rolling the pole piece. In order to ensure the consistency of the thickness of the pole piece after rolling, a dust suction mechanism is often provided in the rolling device. The scraper scrapes off the dust on the outer peripheral surface of the pressure roller, and the dust suction mechanism sucks away the dust scraped off by the scraper. However, in the traditional technology, the position of the dust suction port of the dust suction mechanism is fixed relative to the scraper or the pressure roller and cannot be adjusted according to needs, resulting in poor dust suction effect and thus affecting the rolling effect of the battery pole piece. Summary of the Utility Model

[0005] Based on this, in view of the problem of poor dust suction effect of the dust suction mechanism in the rolling device in the traditional technology, it is necessary to provide a dust suction mechanism and a rolling device that can improve the dust suction effect.

[0006] A dust suction mechanism includes:

[0007] A mounting base;

[0008] An adjustment disk and a dust suction head. The adjustment disk is arranged on the mounting base, and the dust suction head is connected to the adjustment disk; the dust suction head extends along a first direction, and one end of the dust suction head in a second direction intersecting the first direction forms a dust suction port;

[0009] Wherein, in the circumferential direction around the first direction, the adjustment disk is movably arranged relative to the mounting base to change the position of the dust suction head relative to the mounting base in the circumferential direction, thereby adjusting the position of the dust suction port.

[0010] In one embodiment, the dust suction mechanism further includes a first fixing member detachably mounted on the adjustment disk and the mounting base;

[0011] One of the adjusting disc and the mounting seat is provided with an arc-shaped hole extending along the circumferential direction, and the other is provided with a first round hole; the arc-shaped hole is opposite to the first round hole; the position between the arc-shaped hole and the first round hole is adjustable. When the adjusting disc is adjusted relative to the mounting seat to a first target position, the first fixing member passes through the arc-shaped hole and the first round hole to fix the adjusting disc and the mounting seat.

[0012] In one embodiment, the dust suction mechanism includes multiple groups of first hole groups, and each group of the first hole groups includes a corresponding arc-shaped hole and a first round hole arranged opposite to each other.

[0013] The number of the first fixing members is equal to and corresponds one by one to the number of the first hole groups.

[0014] In one embodiment, the cross-sectional shape of the dust suction head is trapezoidal, the dust suction port is formed on the upper base of the trapezoid, and a dust suction cavity communicating with the dust suction port is formed inside the dust suction head; the cross-section is perpendicular to the first direction; and / or

[0015] The dust suction head and the adjusting disc are integrally formed.

[0016] In one embodiment, the dust suction mechanism includes two mounting seats, and one adjusting disc is provided at each of the two ends of the dust suction head in the first direction.

[0017] Each adjusting disc is correspondingly connected to one mounting seat.

[0018] In one embodiment, the adjusting disc is a disc, the first direction is the axial direction of the adjusting disc, and the circumferential direction is the circumferential direction of the adjusting disc.

[0019] In one embodiment, the mounting seat includes a fixed block and an adjusting block, the adjusting disc is connected to the adjusting block, and the position of the adjusting block relative to the fixed block in the third direction is adjustable; the third direction intersects with the first direction.

[0020] In one embodiment, the mounting seat includes a second fixing member detachably mounted on the fixed block and the adjusting block.

[0021] One of the fixed block and the adjusting block is provided with a waist-shaped hole extending along the third direction, and the other is provided with a second round hole corresponding to the waist-shaped hole; the position between the waist-shaped hole and the second round hole is adjustable. When the adjusting block is adjusted relative to the fixed block to a second target position, the second fixing member passes through the waist-shaped hole and the second round hole to fix the adjusting block and the fixed block.

[0022] In one embodiment, the mounting base includes multiple groups of second hole groups, and each group of the second hole groups includes a corresponding kidney-shaped hole and a second round hole arranged oppositely;

[0023] The number of the second fixing members is equal to and corresponds one by one to the number of the second hole groups.

[0024] A rolling device includes a main body, a scraper, a pressure roller and the dust suction mechanism as described above. The pressure roller and the scraper are both mounted on the main body, and the dust suction mechanism is mounted on the main body through the mounting base;

[0025] Both the scraper and the dust suction mechanism extend along the axial direction of the pressure roller. When the position between the adjusting disc and the mounting base changes in the circumferential direction, the position between the dust suction port and the outer peripheral surface of the pressure roller changes; the scraper is used to scrape off the dust on the outer peripheral surface of the pressure roller, and the dust suction mechanism is used to adsorb the dust scraped off by the scraper.

[0026] For the above dust suction mechanism and rolling device, when the dust suction mechanism is mounted on the main body of the rolling device through the mounting base, and when the position of the dust suction port relative to the mounting base changes in the circumferential direction, the position between the dust suction port and the outer peripheral surface of the pressure roller changes, that is, the dust suction angle of the dust suction port will change. In this way, the position of the dust suction port of the dust suction mechanism relative to the scraper or the pressure roller can be adjusted as needed. For example, the position of the dust suction port can be adjusted according to the position where the dust falls or the change of other conditions, ensuring that the dust suction mechanism has a good dust suction effect, ensuring the cleaning effect of the surface of the pressure roller, and further ensuring the rolling effect of the rolling device on the battery pole piece.

[0040] An embodiment of the present application provides a rolling device, including a main body and a pressing roller, and the pressing roller is installed on the main body. The pressing roller is used for rolling the lithium battery electrode sheet formed after coating, and the density of the lithium battery electrode sheet is improved and the thickness is more uniform after being rolled by the pressing roller.

[0041] Referring to Figure 1 and Figure 2 , the rolling device further includes a scraper and a dust suction mechanism 100, and both the scraper and the dust suction mechanism 100 are installed on the main body. The scraper is used for scraping off the dust on the outer peripheral surface of the pressing roller, and the dust suction mechanism 100 is used for adsorbing the dust scraped off by the scraper. Specifically, both the scraper and the dust suction mechanism 100 extend along the axial direction of the pressing roller, and the extension lengths of the scraper and the dust suction mechanism 100 can cover the length of the pressing roller to ensure that the scraper can scrape off all the dust on the pressing roller and at the same time ensure that the dust suction mechanism 100 can adsorb the dust scraped off by the scraper. It can be understood that in some other embodiments, the extension lengths of the scraper and the dust suction mechanism 100 can also be less than the length in the axial direction of the pressing roller, and no limitation is made herein.

[0042] In some embodiments, the dust suction mechanism 100 includes a mounting base 10, an adjustment disk 30, and a dust suction head 20. The mounting base 10 is connected to the main body, the adjustment disk 30 is provided on the mounting base 10, and the dust suction head 20 is connected to the adjustment disk 30. The dust suction head 20 extends in a first direction. Specifically, the first direction is parallel to the axial direction of the pressure roller. The extension length of the dust suction head 20 can be set to be equal to or greater than the length of the pressure roller in the axial direction. Wherein, one end of the dust suction head 20 in a second direction intersecting the first direction forms a dust suction port 21. Specifically, the dust suction port 21 faces the outer peripheral surface of the pressure roller. After the scraper scrapes off the dust on the outer peripheral surface of the pressure roller, the dust suction head 20 sucks away the scraped dust through the dust suction port 21.

[0043] Further, referring to Figure 3 , in the circumferential direction around the first direction, the adjustment disk 30 is movably arranged relative to the mounting base 10 to change the position of the dust suction head 20 relative to the mounting base 10 in the circumferential direction, thereby adjusting the position of the dust suction port 21. With the above arrangement, when the position of the dust suction port 21 changes relative to the mounting base 10 in the circumferential direction, the position of the dust suction port 21 relative to the outer peripheral surface of the pressure roller changes, that is, the dust suction angle of the dust suction port 21 will change. In this way, the position of the dust suction port 21 of the dust suction mechanism 100 relative to the scraper or the pressure roller can be adjusted as needed. For example, the position of the dust suction port 21 can be adjusted according to the position where the dust falls or the change of other conditions, ensuring that the dust suction mechanism 100 has a good dust suction effect, ensuring the cleaning effect of the surface of the pressure roller, and further ensuring the rolling effect of the rolling device on the battery electrode sheet.

[0044] Continuing to refer to Figure 1 and Figure 2 , the dust suction mechanism 100 includes two mounting bases 10, and an adjustment disk 30 is provided at each end of the dust suction head 20 in the first direction. Wherein, each adjustment disk 30 is correspondingly connected to one mounting base 10. In this way, both ends of the dust suction head 20 are supported on the mounting base 10 through an adjustment disk 30, ensuring that the dust suction head 20 is evenly stressed and avoiding sagging due to one end being suspended.

[0045] It should be noted here that since the dust suction mechanism 100 includes two mounting bases 10 and two adjustment disks 30, during adjustment, the positions of the two adjustment disks 30 and the corresponding mounting bases 10 will be adjusted simultaneously, thereby adjusting the position of the dust suction port 21 relative to the outer peripheral surface of the pressure roller.

[0046] Optionally, the adjustment disk 30 is a disk, the first direction is the axial direction of the adjustment disk 30, and the circumferential direction is the circumferential direction of the adjustment disk 30. Of course, in some other embodiments, the shape of the adjustment disk 30 is not limited.

[0047] In some embodiments, the dust suction mechanism 100 further includes a first fixing member (not shown in the figure), and the first fixing member is detachably mounted on the adjusting disk 30 and the mounting seat 10. Continuing to refer to Figure 3 , one of the adjusting disk 30 and the mounting seat 10 is provided with an arc-shaped hole 41 extending in the circumferential direction, and the other is provided with a first circular hole 42. The arc-shaped hole 41 is opposite to the first circular hole 42, and the position between the arc-shaped hole 41 and the first circular hole 42 is adjustable. When the adjusting disk 30 is adjusted to the first target position relative to the mounting seat 10, the first fixing member passes through the arc-shaped hole 41 and the first circular hole 42 to fix the adjusting disk 30 and the mounting seat 10.

[0048] With the above arrangement, when it is necessary to change the relative position between the adjusting disk 30 and the mounting seat 10, the first fixing member is removed from the adjusting disk 30 and the mounting seat 10, the position between the arc-shaped hole 41 and the first circular hole 42 is changed to the first target position, and then the first fixing member is passed through the arc-shaped hole 41 and the first circular hole 42 to fix the adjusting disk 30 and the mounting seat 10, which is convenient and fast to adjust. Specifically, the first fixing member includes a first fixing screw, and the first fixing screw passes through the arc-shaped hole 41 and the first circular hole 42 to fix the adjusting disk 30 and the mounting seat 10.

[0049] It should be noted here that the first target position is the position to which the adjusting disk 30 needs to be adjusted relative to the mounting seat 10 to ensure the dust suction effect, and the first target position is selected according to needs.

[0050] Further, the arc-shaped hole 41 is concentrically arranged on the adjusting disk 30, and the first circular hole 42 is mounted on the mounting seat 10. That is, the center of the circle where the arc-shaped hole 41 is located is the same as the center of the circle where the adjusting disk 30 is located. In this way, by rotating the adjusting disk 30, the relative position between the arc-shaped hole 41 and the first circular hole 42 can be changed, and the arc-shaped hole 41 and the first circular hole 42 can always be aligned when the adjusting disk 30 is rotated, which is convenient for adjustment.

[0051] In other embodiments, the arc-shaped hole 41 can also be provided on the mounting seat 10, and the first circular hole 42 can be provided on the adjusting disk 30, which is not limited here.

[0052] Continuing to refer to Figure 3 , the dust suction mechanism 100 includes multiple groups of first hole groups 40, each group of first hole groups 40 includes a corresponding arc-shaped hole 41 and a first circular hole 42, and the number of the first fixing members is equal to and corresponds to the number of the first hole groups 40 one by one. In this way, the adjusting disk 30 and the mounting seat 10 are fixed by the first fixing members passing through the corresponding first hole groups 40 respectively, ensuring the fixing effect. It can be understood that in some other embodiments, the dust suction mechanism 100 can also only include one group of first hole groups 40 and one first fixing member, which is not limited here either.

[0053] It should be understood that in some other embodiments, the dust suction mechanism 100 can also be arranged in other ways to change the relative position of the adjustment disk 30 with respect to the mounting base 10 in the circumferential direction. For example, it is provided that the dust suction mechanism 100 further includes a first driving member, the first driving member is arranged on the mounting base 10, the adjustment disk 30 is connected to the first driving member, and the first driving member drives the adjustment disk 30 to rotate in the circumferential direction to change the position of the dust suction head 20 and the mounting base 10, thereby adjusting the position of the dust suction port 21.

[0054] In some embodiments, referring to Figure 4 , the mounting base 10 includes a fixed block 11 and an adjustment block 12. The fixed block 11 is connected to the main body, the adjustment disk 30 is connected to the adjustment block 12, and the position of the adjustment block 12 with respect to the fixed block 11 in the third direction is adjustable. The third direction intersects with the first direction.

[0055] Specifically, the third direction is the height direction of the pressure roller device. In this way, the position of the adjustment block 12 with respect to the fixed block 11 is adjustable in the height direction, so that the position of the dust suction head 20 with respect to the pressure roller is adjustable in the height direction, facilitating the dust suction head 20 to be in a suitable position in the height direction.

[0056] Furthermore, the mounting base 10 further includes a second fixing member (not shown in the figure), and the second fixing member is detachably mounted on the fixed block 11 and the adjustment block 12. One of the fixed block 11 and the adjustment block 12 is provided with a waist-shaped hole 131 extending in the third direction, and the other is provided with a second round hole 132. The waist-shaped hole 131 and the second round hole 132 are opposite to each other. The position between the waist-shaped hole 131 and the second round hole 132 is adjustable. When the adjustment block 12 is adjusted to the second target position with respect to the fixing member, the second fixing member passes through the waist-shaped hole 131 and the second round hole 132 to fix the adjustment block 12 and the fixed block 11.

[0057] With the above arrangement, when it is necessary to change the relative position between the adjustment block 12 and the fixed block 11, the second fixing member is removed from the adjustment block 12 and the fixed block 11, the position between the waist-shaped hole 131 and the second round hole 132 is changed to the second target position, and then the second fixing member is passed through the waist-shaped hole 131 and the second round hole 132 to fix the adjustment block 12 and the fixed block 11. The adjustment is convenient and fast. Specifically, the second fixing member includes a second fixing screw, and the second fixing screw passes through the waist-shaped hole 131 and the second round hole 132 to fix the adjustment block 12 and the fixed block 11.

[0058] It should be noted here that the second target position is the position to which the adjustment block 12 needs to be adjusted with respect to the fixed block 11 to ensure the dust suction effect, and the second target position is selected according to needs.

[0059] Optionally, continue to refer to Figure 4, the mounting base 10 includes multiple groups of second hole groups 13. Each group of second hole groups 13 includes a corresponding kidney-shaped hole 131 and a second round hole 132. The number of second fixing members is equal to and corresponds one-to-one with the number of second hole groups 13. In this way, the adjusting block 12 and the fixing block 11 are fixed by multiple second fixing members respectively passing through the corresponding second hole groups 13, ensuring the fixing effect. It can be understood that in some other embodiments, the dust suction mechanism 100 may also include only one group of second hole groups 13, which is not limited herein.

[0060] It should be understood that in some other embodiments, the mounting base 10 may also adopt other settings to change the relative position of the adjusting block 12 and the fixing block 11 in the third direction. For example, it is provided that the mounting base 10 further includes a second driving member. The second driving member is provided on the fixing block 11. The adjusting block 12 is connected to the second driving member. The second driving member drives the adjusting block 12 to move linearly relative to the fixing block 11 along the third direction to change the positions of the adjusting plate and the fixing plate, thereby adjusting the position of the dust suction port 21.

[0061] In some embodiments, referring to Figure 5 , the cross-section of the dust suction head 20 is trapezoidal, and the dust suction port 21 is formed at the upper base of the trapezoid. Among them, the cross-section of the dust suction head 20 is perpendicular to the first direction. Specifically, a dust suction cavity is formed inside the trapezoid. The dust suction head 20 also has a dust outlet. Both the dust suction port 21 and the dust outlet are communicated with the dust suction cavity. In this way, the dust suction port 21 is flat and narrow, with a large suction force, facilitating the inhalation of dust into the dust suction cavity and then discharging it through the dust outlet.

[0062] Continuing to refer to Figure 5 , the cross-section of the dust suction head 20 is isosceles trapezoidal, and the adjusting disk 30 is connected to the end face of the dust suction head 20 in the first direction. Specifically, one of the bottom corners of the trapezoid is connected to the adjusting disk 30, and the vertex of the bottom corner is located at the center of the adjusting disk 30. In this way, when the adjusting disk 30 rotates and adjusts relative to the mounting base 10 around an axis, the dust suction head 20 also rotates around this axis. By observing the position of the adjusting disk 30, the position of the dust suction port 21 can be judged, which is convenient for controlling the position of the dust suction port 21 during adjustment.

[0063] Optionally, the dust suction mechanism 100 further includes a dust outlet pipe 50, and the dust outlet pipe 50 is connected to the dust suction head 20. Specifically, the dust outlet pipe 50 is located on the side surface of the trapezoid of the dust suction head 20 and is multiple to ensure the dust outlet effect.

[0064] Furthermore, the dust suction head 20, the dust outlet pipe 50 and the adjusting disk 30 are integrally formed. In this way, separate manufacturing is avoided, reducing the manufacturing cost. Of course, in some other embodiments, the dust suction head 20, the dust outlet pipe 50 and the adjusting disk 30 may also be separately provided, which is not limited herein.

[0065] Another embodiment of the present application further provides a dust suction mechanism 100, which includes a mounting base 10, an adjustment disk 30, and a dust suction head 20. The adjustment disk 30 is disposed on the mounting base 10, and the dust suction head 20 is connected to the adjustment disk 30. The dust suction head 20 extends in a first direction, and a dust suction port 21 is formed at one end of the dust suction head 20 in a second direction intersecting the first direction. Further, in the circumferential direction around the first direction, the adjustment disk 30 is movably arranged relative to the mounting base 10 to change the position of the dust suction head 20 relative to the mounting base 10 in the circumferential direction, thereby adjusting the position of the dust suction port 21.

[0066] With the above arrangement, when the dust suction mechanism 100 is mounted on the main body of the rolling device through the mounting base 10, and the position of the dust suction port 21 relative to the mounting base 10 changes in the circumferential direction, the position of the dust suction port 21 relative to the outer peripheral surface of the pressing roller changes, that is, the dust suction angle of the dust suction port 21 will change. Thus, the position of the dust suction port 21 of the dust suction mechanism 100 relative to the blade or the pressing roller can be adjusted as needed. For example, the position of the dust suction port 21 can be adjusted according to the position where the dust falls or the change of other conditions, ensuring that the dust suction mechanism 100 has a good dust suction effect, ensuring the cleaning effect of the surface of the pressing roller, and further ensuring the rolling effect of the rolling device on the battery electrode sheet.

[0067] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0068] The above embodiments only express several implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
