[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0037] In addition, the descriptions of "first", "second", etc. in this application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0038] In one embodiment, Figures 1 to 6 As shown, the embodiment of the present application provides a brush cleaning device 1, which may specifically include a brush cleaning module 100, the brush cleaning module 100 including a module mounting seat body 110 having a mounting slot 111, a brush assembly 120, a fixed support shaft 130, an elastic support shaft 140, and a rotary motor 150 for driving the fixed support shaft 130 to rotate. The mounting slot 111 is provided with an active seat 112 and a driven seat 113 on both side walls oppositely arranged in the length direction, the active seat 112 is rotatably provided with a fixed support shaft 130 to support the first end of the brush assembly 120 fixedly installed in the mounting slot 111 through the fixed support shaft 130, and the driven seat 113 is rotatably provided with an elastic support shaft 140 that can be elastically extended and retracted in the length direction of the mounting slot 111 to support the second end of the brush assembly 120 fixedly installed in the mounting slot 111 through the elastic support shaft 140. One side wall of the mounting groove 111 in the width direction is hollowed out so that a part of the brush assembly 120 installed in the mounting groove 111 leaks out of the mounting groove 111 .

[0039] It can be understood that the brush cleaning device 1 of the embodiment of the present application can be used to remove dust from the surface or specific area of ​​the positive and negative electrode rolls of lithium batteries. Therefore, the side wall of the hollow setting can be set toward and adjacent to the product 5 (specifically, the electrode roll) on the roller 2, so as to remove dust from the surface or specific area of ​​the surface through the brush assembly 120 leaking out of the installation groove 111. At the same time, the brush assembly 120 mentioned above can be of different shapes and structures, including but not limited to Figure 1 The multi-stage structure shown or Figure 6 The long strip structure shown is compatible with large and small width pole pieces or pole piece cleaning requirements in specific areas. If you need to clean a specific area of ​​the pole piece, you can replace the special brush such as Figure 1 The brush assembly 120 of the multi-stage structure shown in FIG. If it is necessary to clean the maximum width of the electrode coil, the brush assembly 120 can be replaced as shown in FIG. Figure 6 The brush assembly 120 is shown in a long strip structure.

[0040] In this way, the brush cleaning device 1 provided in the embodiment of the present application can drive the brush assembly 120 to rotate through the rotating motor 150 through the above-mentioned structural setting, so that when the brush assembly 120 performs dust removal and cleaning on the surface or specific area of ​​the positive and negative electrode sheet coil, it can rotate and sweep the corresponding area to provide its cleaning ability. At the same time, since the second end of the brush assembly 120 is supported and fixed by the elastic support shaft 140, and the elastic support shaft 140 can be elastically retracted in the length direction of the installation groove 111, in this way, after the brush assembly 120 is contaminated, the elastic support shaft 140 can be controlled to retract, so that the brush assembly 120 can be quickly taken out of the installation groove 111 for corresponding disassembly, cleaning, and replacement. It can be seen that the brush assembly 120 of the present technical solution is extremely convenient to install and disassemble, which can effectively improve the user experience.

[0041] In some examples, such as Figure 2 and Figure 5 As shown, the elastic support shaft 140 includes a first support shaft body 141, a shaft body mounting sleeve 142, an elastic member 143 and a stopper 144. The shaft body mounting sleeve 142 is rotatably mounted in the driven seat 113 along the length direction of the mounting groove 111. The first end of the first support shaft body 141 has a first support groove for supporting the second end of the fixed brush assembly 120, and the second end of the first support shaft body 141 is elastically assembled in the shaft body mounting sleeve 142 through the elastic member 143, so that the first support shaft body 141 can be elastically extended and retracted in the length direction of the mounting groove 111. The stopper 144 is mounted on the circumference of the shaft body mounting sleeve 142, and can limit the first support shaft body 141 to a first position and a second position spaced apart along the length direction of the mounting groove 111. In this way, the above-mentioned structural setting can better realize that the elastic support shaft 140 is rotatably installed in the driven seat 113, so that the elastic support shaft 140 can elastically expand and contract in the length direction of the installation groove 111, so as to ensure that the second end of the brush assembly 120 is stably supported and fixed, and ensure that the connection between it and the second end of the brush assembly 120 can be quickly disconnected.

[0042] It can be understood that the shaft body installation sleeve 142 mentioned above can be rotatably installed in the driven seat 113 along the length direction of the installation groove 111 through the bearing structure. The first position mentioned above specifically refers to the position where the first support shaft body 141 is in a retracted state in the length direction of the installation groove 111. At this time, the first support groove on the first support shaft body 141 is disengaged from the second end of the brush assembly 120. Through the limiting effect of the limiting member 144, the user can quickly remove the corresponding brush assembly 120 from the installation groove 111. The second position mentioned above specifically refers to the position where the first support shaft body 141 is in a telescopic state in the length direction of the installation groove 111. At this time, the first support groove on the first support shaft body 141 is engaged with the second end of the brush assembly 120 to support and fix the second end of the brush assembly 120, thereby realizing the rapid installation of the brush assembly 120 in the installation groove 111. At the same time, the limiting function of the limiting member 144 ensures that during the use of the brush assembly 120, the second end of the brush assembly 120 will not be dislocated due to the first support shaft 141 being mistakenly retracted in the length direction of the installation groove 111.

[0043] In some examples, such as Figure 2 and Figure 5As shown, the shaft body mounting sleeve 142 includes a hollow tube body and a cover body with a first through hole, the cover body is covered on the first opening of the hollow tube body, and the inner wall of the hollow tube body is provided with an annular step surface arranged opposite to the cover body. The first support shaft body 141 is placed in the hollow tube body, and the first end of the first support shaft body 141 extends out of the hollow tube body through the second opening of the hollow tube body, and the second end of the first support shaft body 141 extends out of the hollow tube body through the first through hole of the cover body. The middle part of the first support shaft body 141 is convexly provided with a step protrusion along its circumferential side, and the step protrusion is limitedly matched with the annular step surface on one side facing the annular step surface. The elastic member 143 is a spring, and the spring is sleeved on the second end of the first support shaft body 141, and the first end of the spring abuts the cover body, and the second end of the spring abuts the side of the step protrusion facing the cover body. In this way, through the above-mentioned structural setting, it is only necessary to pull the second end of the first support shaft 141 so that the step protrusion squeezes the spring while the first end of the first support shaft 141 moves away from the brush assembly 120, thereby making the first support shaft 141 in the first position. At this time, the first support groove on the first support shaft 141 is disengaged from the second end of the brush assembly 120, so that the brush assembly 120 can be quickly removed from the mounting groove 111. When installing the brush assembly 120, the first support shaft 141 can be limited to the first position by the limiting member 144, and then the brush assembly 120 is placed in the installation groove 111, and the first end of the brush assembly 120 is supported and fixed by the fixed support shaft 130. At this time, the elastic support shaft 140 can be rotated to align the first support groove with the flat position of the brush assembly 120, and then the limiting member 144 is released, so that the first support shaft 141 moves toward the brush assembly 120 under the elastic force of the spring, and then the first support groove on the first support shaft 141 is engaged with the second end of the brush assembly 120 to support and fix the second end of the brush assembly 120, so as to achieve the rapid installation of the brush assembly 120 in the installation groove 111. Furthermore, the elastic support shaft 140 also includes a handle 145, and the second end of the first support shaft 141 is fastened to the handle 145 after extending out of the hollow tube body through the first through hole of the cover body. In this way, the structural setting of the handle 145 can facilitate the user to better pull the second end of the first support shaft 141 .

[0044] In some examples, such as Figure 2 and Figure 5As shown, the inner wall of the hollow tube body is penetrated with a second through hole, and the first support shaft body 141 is penetrated with a first limiting hole 1411 and a second limiting hole 1412 along its radial direction, and the first limiting hole 1411 and the second limiting hole 1412 are spaced apart in the length direction of the first support shaft body 141. The limiting member 144 is a limiting pin elastically assembled in the second through hole, and the limiting pin can be clamped and matched with the first limiting hole 1411 under the elastic force to limit the first support shaft body 141 in the first position, or clamped and matched with the second limiting hole 1412 to limit the first support shaft body 141 in the second position. In this way, the first support shaft body 141 can be limited to the first position by clamping and matching with the first limiting hole 1411, which can better facilitate the user to quickly remove the corresponding brush assembly 120 from the installation groove 111 or quickly install the brush assembly 120 in the installation groove 111, that is, make these operations more convenient. The first support shaft 141 is limited to the second position by the engagement of the limit pin with the second limit hole 1412, thereby ensuring that during the use of the brush assembly 120, the second end of the brush assembly 120 will not be dislocated due to the first support shaft 141 being accidentally retracted in the length direction of the mounting groove 111.

[0045] It can be understood that in order to facilitate the user to better operate the limit pin, before releasing the limit pin on the corresponding limit hole (the first limit hole 1411 or the second limit hole 1412), the brush assembly 120 can be driven by the rotating motor 150 to drive the elastic support shaft 140 to rotate so that the second through hole is set upward, or the elastic support shaft 140 can be manually rotated directly so that the second through hole is set upward.

[0046] In some examples, such as Figure 2 As shown, the fixed support shaft 130 includes a second support shaft body, the first end of the second support shaft body has a second support groove for supporting the first end of the fixed brush assembly 120, and the second end of the second support shaft body is rotatably mounted on the active seat 112. In this way, through the above-mentioned structural setting, the first end of the brush assembly 120 can be better supported and fixed by the fixed support shaft 130 through the interference fit between the second support groove and the first end of the brush assembly 120.

[0047] It can be understood that the second end of the second supporting shaft can be rotatably mounted on the active seat 112 via a bearing structure.

[0048] In some examples, such as Figure 2As shown, the brush cleaning module 100 further includes a protective cover 160, which is disposed on the upper notch of the mounting slot 111. In this way, the protective cover 160 can be used to protect the brush assembly 120 from being disturbed by the external environment during use, and at the same time, it can also prevent the brush assembly 120 from blowing dust and other impurities into the external environment during use.

[0049] In some examples, such as Figure 2 As shown, the brush cleaning module 100 also includes a suction dust removal component 170, which includes a suction dust removal pipe and a suction dust removal machine that drives the suction dust removal pipe to perform suction dust removal work, and the end of the suction dust removal pipe away from the suction dust removal machine is connected to the bottom wall of the installation slot 111. In this way, through the above-mentioned structural arrangement, when the brush assembly 120 performs dust removal and cleaning on the surface or specific area of ​​the positive and negative electrode sheet coils of the lithium battery, the suction dust removal machine can drive the suction dust removal pipe to perform suction dust removal work to suck away the dust appearing in the installation slot 111, so as to slow down the speed at which the brush assembly 120 is contaminated as much as possible, reduce the frequency of disassembly, cleaning and replacement of the brush assembly 120, bring great convenience to the user, and further effectively improve the user experience.

[0050] In some examples, such as Figure 2 As shown, the brush cleaning module 100 also includes a cleaning blade 180, which is fixed in the mounting groove 111 and is arranged adjacent to the other side wall of the mounting groove 111 in the width direction away from the side wall of the hollow setting. The cleaning blade 180 also extends along the length direction of the mounting groove 111 and is arranged against the side of the brush assembly 120 in the width direction of the mounting groove 111. In this way, through the above-mentioned structural arrangement, the cleaning blade 180 can simultaneously clean the brush assembly 120 during the use of the brush assembly 120, and cooperate with the suction and dust removal assembly 170 to suction and dust the mounting groove 111, which can further slow down the speed at which the brush assembly 120 is contaminated, and further reduce the frequency of disassembly, cleaning and replacement of the brush assembly 120, which brings great convenience to the user.

[0051] In some examples, such as Figure 2As shown, the brush cleaning device 1 also includes an X-axis driving component 200 for driving the brush cleaning module 100 to move in the horizontal X-axis direction and a Y-axis driving component 300 for driving the brush cleaning module 100 to move in the horizontal Y-axis direction, so that the brush cleaning module 100 can be freely switched between the working position and the disassembly and washing position under the joint action of the X-axis driving component 200 and the Y-axis driving component 300. In this way, through the above-mentioned structural setting, the brush cleaning module 100 can avoid the working position in contact with the product 3 when disassembling and installing the brush assembly 120, ensuring the disassembly and washing position that is not interfered by the product, and quickly disassembling and assembling the brush assembly 120, so as to further facilitate the corresponding operation of the user and effectively improve the user's experience.

[0052] The above description is only a preferred embodiment of the present application, and does not limit the patent scope of the present application. All equivalent structural changes made by using the contents of the present application specification and drawings under the inventive concept of the present application, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present application.
