Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery production and manufacturing, and in particular to a pole tab rolling device and pole piece processing equipment. Background Art

[0002] With the widespread application of lithium batteries in the automotive market, the demand for lithium batteries and quality requirements are also increasing. Lithium battery production equipment is an important factor affecting the production capacity, precision and quality of lithium batteries.

[0003] In order to trim the wrinkles on the surface of the pole lug, the calendering wheel of the pole lug calendering equipment is used to pre-press the pole lug during the production process, so that the pole lug is extended, greatly reducing the frequency of tape breakage under the high-pressure compaction process. Since the specifications and sizes of the pole pieces are different, the position of the pole lug area is also inconsistent, so the calendering wheel needs to be able to move along its own axis. The above movement causes the parallelism between the calendering wheel and the pressing roller to change, resulting in uneven pressure when rolling the pole lug, and the pole lug is crushed and broken. Therefore, it is necessary to readjust the calendering wheel after moving. The existing technology generally adjusts it by plugging in thin sheets, which is difficult to adjust and inefficient.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0057] Please refer to Figure 1-7 An embodiment of the present application provides a tab calendering device 100 , which includes a base 10 , an inner support seat 20 , a first adjustment member 30 , a calendering wheel 40 , two sets of mounting seats 50 and a second adjustment member 60 .

[0058] Please refer to Figure 1 and Figure 2 The base 10 is used to provide an installation reference for the inner support seat 20 .

[0059] The inner support seat 20 is disposed on the base 10 and can rotate in a first plane relative to the base 10. The first plane is parallel to the axial direction of the pressure roller 400. The inner support seat 20 can rotate in the first plane relative to the base 10, that is, the inner support seat 20 can rotate with the normal perpendicular to the first plane as the rotation axis. The inner support seat 20 has a mounting groove.

[0060] The first adjusting member 30 is used to adjust the rotation angle of the inner support seat 20 relative to the base 10. That is, to adjust the rotation angle of the inner support seat 20 relative to the base 10 in the first plane.

[0061] The calendering wheel 40 is used to cooperate with the pressing roller to calender the pole ear. The pole ear is the pole ear of the pole piece. During the calendering process, the pressing roller 400 and the calendering wheel 40 need to remain parallel. It should also be noted that the relative position of the pole ear will change for pole pieces of different specifications.

[0062] The axial ends of the calendering wheel 40 are rotatably disposed on two sets of mounting seats 50. The two sets of mounting seats 50 can respectively support the two ends of the calendering wheel 40. It can be understood that each set of mounting seats 50 includes at least one mounting seat.

[0063] The two sets of mounting seats 50 are sequentially arranged in the mounting groove along the axial direction of the calendering wheel 40. The second adjusting member 60 is used to adjust the positions of the two sets of mounting seats 50 relative to the inner support seat 20 along the first direction to adjust the angle between the calendering wheel 40 and the first plane, wherein the first direction is perpendicular to the first plane.

[0064] It is understandable that the positions of the two sets of mounting seats 50 on the inner support seat 20 can be adjusted by the second adjusting member 60. In the first direction, when the adjustment amounts of the two sets of mounting seats 50 relative to the inner support seat 20 are different, the positions of the two ends of the calendering wheel 40 along its own axis in the first direction will change. The first direction is the normal direction of the first plane.

[0065] In the above embodiment, the axial ends of the calendering wheel 40 are rotatably arranged on two groups of mounting seats 50 respectively, and the two groups of mounting seats 50 are sequentially arranged in the mounting groove of the inner support seat 20 along the axial direction of the calendering wheel 40. The support seat is arranged on the base 10 and can rotate relative to the base 10 in the first plane. The rotation angle of the inner support seat 20 relative to the base 10 in the first plane is adjusted by the first adjusting member 30, so as to achieve the adjustment of the rotation angle of the calendering wheel 40 relative to the base 10 in the first plane. The two groups of mounting seats 50 are respectively adjusted along the first direction perpendicular to the first plane by the second adjusting member 60, so that the angle between the calendering wheel 40 and the first plane is adjusted, so as to achieve the adjustment of the axial ends of the calendering wheel 40 in the first direction. Thereby, the calendering wheel 40 can be adjusted to a position parallel to the pressing roller 400, and the above position makes the pressure exerted by the pressing roller 400 and the calendering wheel 40 on the tab relatively uniform. Since the second adjusting member 60 is used to adjust the positions of the two groups of mounting seats 50, and the first adjusting member 30 is used to adjust the angle of the inner support seat 20, the objects adjusted by the second adjusting member 60 and the first adjusting member 30 are different. This avoids the problem of the second adjusting member 60 and the first adjusting member 30 affecting each other due to the same adjustment objects, reduces the difficulty of adjustment, and improves the efficiency of adjustment.

[0066] Please refer to Figure 2 and Figure 3 In some embodiments, the second adjusting member 60 includes two groups of wedge block assemblies 61, each group of wedge block assemblies 61 is correspondingly arranged between the bottom of a mounting seat 50 and the inner support seat 20, and the wedge block assembly 61 can adjust its own size along the first direction. Among them, the wedge block assembly 61 includes two wedge blocks, and the wedge blocks have wedge surfaces that cooperate with each other. The wedge block assembly 61 can amplify the force applied thereto, and the stability of the structure is good.

[0067] It is understandable that the size of the wedge block assembly 61 along the first direction is adjusted, which will adjust the position of the corresponding mounting seat 50 in the first direction. By providing two wedge block assemblies 61, the positions of the two groups of mounting seats 50 in the first direction are adjusted respectively, so as to achieve the adjustment of the positions of the two ends of the calendering wheel 40 along its own axis in the first direction.

[0068] In some embodiments, the wedge assembly 61 includes two mutually cooperating first wedges 611 and second wedges 612. The wedge surface of the first wedge 611 and the wedge surface of the second wedge 612 cooperate with each other. The first wedge 611 is fixed to the bottom of the mounting seat 50 so that there is no relative movement between the first wedge 611 and the mounting seat 50.

[0069] The second adjusting member 60 includes a plurality of first supporting members 62, each wedge block assembly 61 is provided with at least one first supporting member 62, and at least one first supporting member 62 can push the second wedge block 612 to reciprocate in the second direction, wherein the second direction is parallel to the first plane and perpendicular to the axial direction of the calendering wheel 40. The second direction is perpendicular to the first direction.

[0070] It can be understood that the reciprocating movement of the second wedge block 612 in the second direction causes the second wedge block 612 and the first wedge block 611 to move relative to each other, thereby changing the overall size of the first wedge block 611 and the second wedge block 612 in the first direction.

[0071] The fixing method of the first wedge block 611 and the mounting seat 50 is not limited. In some embodiments, the first wedge block 611 and the mounting seat 50 are integrally formed.

[0072] The number of first top holding members 62 corresponding to each wedge block assembly 61 is not limited. In some embodiments, each wedge block assembly 61 is correspondingly provided with a group of first top holding members 62, and the number of each group of first top holding members 62 is one. The first top holding member 62 can be connected to the second wedge block 612, and the second wedge block 612 is moved by moving the first top holding member 62, thereby changing the overall size of the first wedge block 611 and the second wedge block 612 in the first direction.

[0073] Please refer to Figure 3In other embodiments, each wedge assembly 61 is correspondingly provided with two sets of first supporting members 62, and the two sets of first supporting members 62 are respectively threadedly connected to the side walls of the inner support seat 20 opposite to each other along the second direction. The two sets of first supporting members 62 can change their positions on the side walls of the inner support seat by rotating.

[0074] Among them, one group of first supporting members 62 can extend out of the side wall of the inner support seat 20 and abut against one end of the second wedge block 612 along the second direction, and another group of first supporting members 62 can extend out of the side wall of the inner support seat 20 and abut against the other end of the second wedge block 612 along the second direction.

[0075] In this way, when it is necessary to adjust the second wedge block 612 along the second direction, one group of first supporting members 62 can be rotated so that the length of the first supporting members 62 extending out of the side wall increases, thereby supporting and pushing the second wedge block 612. After the adjustment is completed, another group of first supporting members 62 can be rotated so that they support the second wedge block 612, thereby achieving the positioning of the second wedge block 612.

[0076] Please refer to Figure 2 In some embodiments, the base 10 has a receiving groove 10b, the inner support seat 20 is arranged in the receiving groove 10b, and a through hole is opened on the side wall of the receiving groove 10b, that is, the side plate of the inner support seat 20, and the first top holding member 62 passes through the through hole and is threadedly connected to the inner support seat 20.

[0077] In order to limit the sliding track of the second wedge block 612. In some embodiments, the inner wall of the inner support seat 20 at both ends of the axial direction of the calendering wheel 40 has two protruding and parallel first limit strips 21, the two first limit strips 21 extend along the second direction, and a first slide groove is defined between the two first limit strips 21, and the second wedge block 612 can slide in the first slide groove. The two first limit strips 21 can limit the two ends of the second wedge block 612 along the axial direction of the calendering wheel 40, thereby improving stability, and at the same time, the second wedge block 612 can maintain alignment with the first wedge block 611.

[0078] In order to limit the sliding track of the mounting seat 50. In some embodiments, the inner wall of the inner support seat 20 at both ends of the axial direction of the calendering wheel 40 has two protruding and parallel second limit strips 22, the two second limit strips 22 extend along the first direction, and a second slide groove is defined between the two second limit strips 22, and the mounting seat 50 can slide in the second slide groove. Specifically, when the size of the wedge block assembly 61 along the first direction is adjusted, the mounting seat 50 will rise and fall along the first direction. By setting the second limit strips 22, the above-mentioned lifting process can be guided, thereby further ensuring the parallel accuracy of the calendering wheel 40 and the pressing roller 400.

[0079] It is understandable that the first limiting strip 21 is located at the bottom wall of the installation groove, and the second limiting strip 22 is located at the side wall of the installation groove. The first limiting strip 21 can be connected to the second limiting strip 22.

[0080] Please refer to Figure 3 and Figure 5 , in order to guide the rotation of the inner support seat 20 and the base 10. In some embodiments, one of the inner support seat 20 and the base 10 has a limiting hole 10a, and the other has a boss 23 that can be inserted into the limiting hole 10a and relatively rotated in the first plane. The base 10 and the inner support seat 20 rotate with the center line of the boss 23 as the rotation axis. The boss 23 cooperates with the limiting groove to limit the movement of the inner support seat 20 relative to the base 10 in the first plane.

[0081] The structure of the limiting hole 10a is not limited, for example, it can be a circular hole or an annular hole. The structure of the protrusion 23 is not limited, for example, it can be a circular protrusion 23 or an annular protrusion 23.

[0082] The protruding column 23 is formed on the bottom surface of the inner support seat 20 , and the limiting hole 10 a is formed on the surface of the base 10 opposite to the bottom surface of the inner support seat 20 .

[0083] Furthermore, in some embodiments, the limiting hole 10 a or the protruding column 23 is located at the geometric center of the inner support seat 20 on the first plane to facilitate the subsequent adjustment of the first adjusting member 30 .

[0084] It is understandable that the structure of the first adjusting member 30 is not limited. It only needs to be able to adjust the rotation angle of the inner support seat 20 relative to the base 10 and lock the inner support member after adjustment so that it cannot rotate relative to the base 10.

[0085] In some embodiments, the first adjusting member 30 includes a plurality of second connecting members, and each mounting seat 50 is provided with two second connecting members.

[0086] Two second connecting members are arranged on the same side plate of the base 10, one of which passes through the side plate of the base 10 along the second direction and is threadedly connected to the mounting seat 50, and the other second connecting member is threadedly connected to the side plate of the base 10 and supported on the mounting seat 50 along the second direction.

[0087] The side plate of the base 10 is provided with a through hole for the second connecting member to pass through. A second connecting member is threadedly connected to the mounting seat 50, so that the mounting seat 50 can be moved in the second direction by moving the second connecting member in the second direction.

[0088] By arranging the two second connecting members on one side plate of the base 10, the adjustment of the two second connecting members can be facilitated, especially in an environment where the installation and adjustment of the other side plates of the base 10 are limited.

[0089] Another second connecting member is threadedly connected to the side plate of the base 10 and supported on the mounting seat 50 along the second direction, so that after the mounting seat 50 moves to the preset position, the two second connecting members can cooperate to lock the inner support member to prevent it from rotating relative to the base 10.

[0090] The specific structures of the two second connecting members are not limited. In some embodiments, one of the second connecting members is a screw or a threaded rod, and the other second connecting member is a top screw.

[0091] Please refer to Figure 2 and Figure 6 In order to reduce the rotation resistance of the calendering wheel 40. In some embodiments, the tab calendering device 100 includes a bearing 70, the mounting seat 50 has a bearing groove 50a, the bearing 70 is sleeved at both axial ends of the calendering wheel 40, and is installed in the bearing groove 50a. The bearing 70 can be a rolling bearing 70, including an inner ring, an outer ring, and balls or rollers between the inner ring and the outer ring.

[0092] Please refer to Figure 3 In some embodiments, the inner support seat 20 includes a support seat body and a plurality of bearing pressure plates 24. The bearing pressure plates 24 are connected to the support seat body and are pressed onto the outer ring surface of the outer ring of the bearing 70 to limit the movement of the calendering wheel 40 relative to the mounting seat 50 along the first direction.

[0093] Among them, each bearing 70 can be correspondingly provided with two bearing pressure plates 24, and the two bearing pressure plates 24 are plate structures, which are pressed on the bearing 70, and the bearing pressure plates 24 can be fixed on the support seat body by a fastening method, wherein the fastening method can be a method of fastening by screws.

[0094] In some embodiments, the mounting seat 50 includes a groove body 52 and a plurality of bearing baffles 51, the bearing baffles 51 are connected to the groove body 52, the bearing groove 50a is located on the groove body 52, the bearing baffles 51 are distributed on the side of the bearing 70 away from the calendering wheel 40, and abut against the outer ring of the bearing 70 to limit the movement of the calendering wheel 40 relative to the mounting seat 50 along its own axial direction. Among them, each bearing 70 is correspondingly provided with a bearing baffle 51, and the position of the calendering wheel 40 relative to the mounting seat 50 along its own axial direction is fixed by the cooperation of the two bearing baffles 51.

[0095] The bearing baffle 51 may be in an arc shape and is coaxially arranged with the bearing 70. The bearing baffle 51 is fastened to the groove member 52 by fasteners.

[0096] It is understandable that the pole piece includes foil. During the operation of the calendering wheel 40, the calendering wheel 40 is very easy to stick to the foil and other debris. If the calendering wheel 40 is not cleaned, it will affect the subsequent calendering effect, affect the quality of the pole piece, and increase the probability of belt breakage. The existing cleaning solution for the calendering wheel 40 is to remove the calendering wheel 40 for cleaning. Due to space limitations, this method is not only time-consuming but also difficult to operate and install, has high operating risks, takes a long time to disassemble and install, and is inefficient.

[0097] For this, please refer to Figure 2 and Figure 4 In some embodiments, the tab calendering device 100 includes a scraping assembly 80, and the scraping assembly 80 includes a scraper 81. The scraper 81 can scrape the outer annular surface of the calendering wheel 40 to remove debris from the outer annular surface of the calendering wheel 40.

[0098] The material of the scraper 81 is not limited. In order to reduce the damage of the scraper 81 to the surface of the calendering wheel 40, in some embodiments, the hardness of the material of the scraper 81 is lower than that of the calendering wheel 40. The material of the scraper 81 can be resin.

[0099] It is understandable that, in order to remove the debris, the blade of the scraper 81 may be parallel to the axial direction of the calendering wheel 40 .

[0100] It is understandable that the installation structure of the scraper 81 is not limited.

[0101] In some embodiments, the scraping assembly 80 includes an adjustment block 82, a first clamping plate 83, and a second clamping plate 84. The scraper 81 is clamped between the first clamping plate 83 and the second clamping plate 84. The adjustment block 82 is set on the inner support seat 20 and can adjust its relative position with the inner support seat 20. The first clamping plate 83 and the second clamping plate 84 are detachably fixed on the adjustment block 82.

[0102] In this way, by adjusting the relative position of the adjustment block 82 and the inner support seat 20, the position of the scraper 81 relative to the calendering wheel 40 can be adjusted, so that after the calendering wheel 40 is adjusted, the scraping effect of the scraper 81 is still maintained.

[0103] There is no limit to the adjustment method of the adjustment block 82. For example, the adjustment block 82 is fastened to the inner support seat 20 by a fastener. The fastener penetrates the inner support seat 20 from bottom to top and is threadedly connected to the adjustment block 82. The inner support seat 20 has a through circular hole for the fastener to pass through. The through circular hole and the fastener are clearance matched, and the clearance can be used as an adjustment margin.

[0104] To prevent the scraped debris from being re-adhered to the calender wheel 40. Figure 2 and Figure 7In some embodiments, the tab calendering device 100 includes a dust suction assembly 90, and the dust suction assembly 90 includes a dust suction cover 91 with a negative pressure port. It can be understood that the negative pressure port is connected to a negative pressure source to provide negative pressure to suck in debris.

[0105] The inner support seat 20 and the base 10 are provided with a window 20a connected to the mounting groove, and one end of the dust cover 91 having a negative pressure port extends from the window 20a so that the negative pressure port is aligned with the position where the scraper 81 contacts the calendering wheel 40. It can be understood that at least the lower portion of the calendering wheel 40 is in the mounting groove, and the scraper 81 is arranged on the upper surface of the bottom plate of the inner support seat 20 and faces the window 20a. By aligning the negative pressure port with the position where the scraper 81 contacts the calendering wheel 40, the debris can be directly sucked away after the scraper 81 scrapes it.

[0106] The dust collection assembly 90 includes a dust collection bracket, which is used to fix the dust collection cover 91 on the base 10.

[0107] The embodiment of the present application further provides a tab calendering device, which includes a calendering wheel 40 , and the calendering wheel 40 is used to cooperate with a pressing roller 400 to calender the tab.

[0108] The tab calendering device includes a base 10, an inner support seat 20, a first adjusting member 30, a second inner support seat and a second adjusting member 60. The inner support seat 20 is arranged on the base 10 and can rotate in a first plane relative to the base 10, and the first plane is parallel to the axial direction of the pressing roller 400. The first adjusting member is used to adjust the rotation angle of the inner support seat 20 relative to the base 10. The calendering wheel 40 is rotatably arranged on the second inner support seat, and the second inner support seat can rotate in a second plane, and the second plane passes through the axis of the calendering wheel 40 and is perpendicular to the first plane. The second adjusting member 60 is used to adjust the rotation angle of the second inner support seat relative to the inner support seat 20. Among them, the second inner support seat includes two sets of mounting seats.

[0109] Please refer to Figure 8 The embodiment of the present application also provides a pole piece processing equipment, which includes a pole tab rolling device 100, a pressing roller 400, a screw assembly 200 and a driving member 300.

[0110] There is a gap between the pressing roller 400 and the calendering wheel 40 for the pole piece to pass through, and the pressing roller 400 and the calendering wheel 40 cooperate to calender the pole lugs of the pole piece.

[0111] The lead screw assembly 200 is used to move the tab calendering device 100 along the axial direction of the calendering wheel 40. It is understandable that when the position of the tab along the axial direction of the calendering wheel 40 changes, the tab calendering device 100 needs to be moved by the lead screw assembly 200 to ensure that the calendering wheel 40 can still align with the tab. Among them, the reason for the change in the position of the tab along the axial direction of the calendering wheel 40 is mainly caused by the change in the specifications of the pole piece.

[0112] The lead screw of the lead screw assembly 200 is arranged parallel to the pressing roller 400. The lead screw nut of the lead screw assembly 200 is connected to the tab calendering device 100, and the tab calendering device 100 moves along the axial direction of the calendering wheel 40 by driving the lead screw to rotate.

[0113] The driving member 300 is used to push the tab calendering device 100 to move toward the pressing roller 400. The pushing direction is parallel to a plane perpendicular to the axial direction of the calendering wheel 40. The driving member 300 may be a hydraulic cylinder.

[0114] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present invention. In addition, the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.
