Description

Technical Field

[0001] This utility model relates to the field of electrode rolling technology, and in particular to a rolling equipment and an electrode. Background Technology

[0002] Interval-coated electrodes typically have single-sided and double-sided coating areas. When rolling these electrodes, the rolling device needs to set different roller gaps for the single-sided and double-sided coating areas. The rolling device needs to switch the roller gap when passing the junction of the single and double sides. When switching from a small roller gap to a large roller gap, overpressure is likely to occur at the junction of the single and double sides, which can lead to electrode breakage at that point.

[0003] Therefore, in related technologies, when the rolling equipment rolls from the single-sided coating area to the double-sided coating area, it is easy to cause overpressure at the junction of the single and double sides. Utility Model Content

[0004] This utility model provides a roller pressing device to solve the problem that overpressure easily occurs at the junction of single and double sides when roller pressing from a single-sided coating area to a double-sided coating area in related technologies.

[0005] The roller pressing equipment of this utility model embodiment is characterized by comprising:

[0006] A rolling assembly includes a fixed roller and an adjusting roller, the fixed roller and the adjusting roller being disposed opposite to each other to define a roller gap through which the electrode sheet passes, the adjusting roller being movable between a rolled electrode sheet position and a dislodged electrode sheet position.

[0007] A first detection component is located upstream of the rolling assembly;

[0008] The first detection component is used to collect coating information of the electrode, including the position information of the single-sided coating area, the position information of the double-sided coating area, and the position information of the boundary between the single-sided coating area and the double-sided coating area;

[0009] The control module drives the adjusting roller to move between the roller-pressed electrode position and the electrode-detached position according to the coating information, so that the adjusting roller is located at the electrode-detached position when passing the junction of the single-sided coating area and the double-sided coating area, and is located at the roller-pressed electrode position when passing the single-sided coating area and the double-sided coating area.

[0010] When the roller pressing assembly of the roller pressing equipment in this embodiment of the utility model passes through the junction of the single-sided coating area and the double-sided coating area, it can first move from the roller pressing electrode position to the electrode detachment position, and then move from the electrode detachment position to the electrode roller pressing position.

[0011] For example, when the roll forming assembly rolls from the double-sided coating area to the single-sided coating area, when passing the boundary between the single-sided and double-sided coating areas, the roll forming first moves from the electrode rolling position to the electrode detachment position, and then moves from the electrode detachment position to the electrode rolling position. That is, the roll forming assembly can skip the boundary between the single-sided and double-sided coating areas. This avoids applying excessive roll forming pressure to the boundary between the single-sided and double-sided coating areas when switching from a small roll gap to a large roll gap, which would cause overpressure at the boundary between the single-sided and double-sided coating areas.

[0012] Therefore, the roller pressing equipment of this utility model embodiment can avoid the problem of over-pressure at the junction of single and double sides when rolling from the single-sided coating area to the double-sided coating area.

[0013] In some embodiments, the rolling assembly further includes a driving assembly, which is signal-connected to the control module. The control module controls the driving assembly to move the adjusting roller between the rolling electrode position and the electrode detachment position.

[0014] In some embodiments, the drive assembly includes a hydraulic cylinder, the drive end of which is connected to the adjusting roller to move the adjusting roller between the roller-pressed electrode position and the electrode-detached position.

[0015] In some embodiments, the first detection component includes a first sensor and a second sensor, wherein the first sensor is signal-connected to the control module and the second sensor is signal-connected to the control module;

[0016] The first sensor is used to collect the color information of the electrode;

[0017] The second sensor is used to collect the electrode travel information;

[0018] The control module derives the coating information based on the color information and the conveyor belt information.

[0019] In some embodiments, the first sensor includes a color mark sensor, which is disposed above the electrode and is signal-connected to the control module.

[0020] In some embodiments, the second sensor includes an encoder and the code wheel;

[0021] The code wheel abuts against the electrode, so that the electrode drives the code wheel to rotate;

[0022] The code wheel is connected to the encoder, and the encoder is signal-connected to the control module.

[0023] In some embodiments, a first switching point and a second switching point are provided on the electrode near the junction of the single-sided coating area and the double-sided coating area;

[0024] In the conveying direction of the electrode, the first switching point is located downstream of the second switching point;

[0025] When the adjusting roller passes the first switching point, the adjusting roller switches from the position of pressing the electrode to the position of disengaging from the electrode.

[0026] When the adjusting roller passes the second switching point, the adjusting roller switches from the position of detaching from the electrode to the position of pressing the electrode.

[0027] In some embodiments, the rolling position includes a single-sided rolling position and a double-sided rolling position.

[0028] When the adjusting roller passes through the single-sided coating area of ​​the electrode sheet, the adjusting roller is in the single-sided rolling position;

[0029] When the adjusting roller passes through the double-sided coating area of ​​the electrode, the adjusting roller is in the double-sided rolling position.

[0030] In some embodiments, the roller pressing equipment of this utility model further includes a second detection component, which is located downstream of the roller pressing component and is signal-connected to the control module.

[0031] The second detection component is used to collect the thickness of the single-sided coating area and the thickness of the double-sided coating area of ​​the electrode sheet after rolling.

[0032] The control module controls the size of the roller gap at the position of the roller pressing electrode based on the relationship between the thickness of the single-sided coating area of ​​the rolled electrode and the preset thickness of the single-sided coating area.

[0033] The control module controls the size of the roller gap at the position of the roller pressing electrode based on the relationship between the thickness of the double-sided coating area of ​​the rolled electrode and the preset thickness of the double-sided coating area.

[0034] This utility model also provides an electrode sheet.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0049] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal encapsulation of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0050] In order to solve the problem that overpressure easily occurs at the junction of single and double sides when the roller pressing equipment in the related technology rolls from the single-sided coating area 401 to the double-sided coating area 402.

[0051] This utility model provides a roller pressing device.

[0052] The roller pressing equipment of this utility model embodiment includes a roller pressing component 1, a first detection component 2, and a control module 3.

[0053] The rolling assembly 1 includes a fixed roller 101 and an adjusting roller 102. The fixed roller 101 and the adjusting roller 102 are arranged opposite to each other to define a roller gap through which the electrode 4 passes. The adjusting roller 102 can move between the position where the electrode 4 is rolled and the position where the electrode 4 is disengaged.

[0054] The first detection component 2 is located upstream of the roll forming component 1; the first detection component 2 is used to collect the coating information of the electrode sheet 4, including the position information of the single-sided coating area 401, the position information of the double-sided coating area 402, and the position information of the junction 403 of the single-sided coating area and the double-sided coating area.

[0055] It is understandable that the coating area on the electrode 4 includes a double-sided coating area 402 and a single-sided coating area 401. The double-sided coating area 402 has active material layers coated on both sides of the electrode 4 in the thickness direction, and the single-sided coating area 401 has active material layers coated on one side of the electrode 4 in the thickness direction. The junction 403 between the single-sided coating area and the double-sided coating area is the junction between the single and double sides.

[0056] The control module 3 drives the adjusting roller 102 to move between the roller pressing electrode 4 position and the detached electrode 4 position according to the coating information, so that the adjusting roller 102 is located at the detached electrode 4 position when passing the junction 403 of the single-sided coating area and the double-sided coating area, and is located at the roller pressing electrode 4 position when passing the single-sided coating area 401 and the double-sided coating area 402.

[0057] Optionally, the control module 3 is an electronic device such as a microprocessor, PLC, or CPU that can process data information and send instructions.

[0058] When the roller pressing assembly 1 of the roller pressing equipment of this utility model passes through the junction 403 of the single-sided coating area and the double-sided coating area, it can first move from the roller pressing electrode 4 position to the detached electrode 4 position, and then move from the detached electrode 4 position to the roller pressing position of the electrode 4.

[0059] For example, when the roll forming assembly 1 rolls from the double-sided coating area 402 to the single-sided coating area 401, when passing the junction 403 between the single-sided coating area and the double-sided coating area, the roll forming first moves from the position of rolling the electrode 4 to the position of detaching from the electrode 4, and then moves from the position of detaching from the electrode 4 to the position of rolling the electrode 4. That is, the roll forming assembly 1 can skip the junction 403 between the single-sided coating area and the double-sided coating area. This avoids applying excessive roll forming pressure to the junction 403 between the single-sided coating area and the double-sided coating area when switching from a small roll gap to a large roll gap, which would cause overpressure at the junction 403 between the single-sided coating area and the double-sided coating area.

[0060] Therefore, the roller pressing equipment of this utility model embodiment can avoid the problem of over-pressure at the junction of single and double sides when rolling from the single-sided coating area 401 to the double-sided coating area 402.

[0061] In some embodiments, the rolling assembly 1 further includes a driving assembly 103, which is signal-connected to the control module 3. The control module 3 controls the driving assembly 103 to drive the adjusting roller 102 to move between the rolling electrode 4 position and the disengaged electrode 4 position.

[0062] It is worth noting that the position of the drive component 103 in the attached figure is for illustrative purposes only. In actual implementation, it can be set according to the drive requirements. The line connecting the drive component 103 and the adjusting roller 102 only indicates that there is a transmission connection between the drive component 103 and the adjusting roller 102. The specific transmission structure can be set according to actual needs.

[0063] Furthermore, the drive assembly 103 includes a hydraulic cylinder 1031, the drive end of which is connected to the adjusting roller 102 to drive the adjusting roller 102 to move between the position of rolling the electrode 4 and the position of disengaging from the electrode 4. The hydraulic cylinder 1031 is connected to the control module 3 so that the control module 3 controls the hydraulic cylinder 1031 to drive the adjusting roller 102 to move between the position of rolling the electrode 4 and the position of disengaging from the electrode 4.

[0064] It is understandable that the hydraulic cylinder 1031 has a fixed end and a driving end. When installing the hydraulic cylinder 1031, the fixed end can be fixed and the driving end can be connected to the adjusting roller 102 to drive the adjusting roller 102 to move between the position of rolling the electrode 4 and the position of disengaging from the electrode 4.

[0065] In some embodiments, the first detection component 2 includes a first sensor 201 and a second sensor 202. The first sensor 201 is signal-connected to the control module 3, and the second sensor 202 is signal-connected to the control module 3. The first sensor 201 is used to collect color information of the electrode 4, and the second sensor 202 is used to collect the tape travel information of the electrode 4.

[0066] It is understandable that the first sensor 201 is signal-connected to the control module 3 to transmit the color information it collects to the control module 3, and the second sensor 202 is signal-connected to the control module 3 to transmit the tape transport information it collects to the control module 3.

[0067] The control module 3 derives the coating information based on the color information and the conveyor belt information.

[0068] Furthermore, the first sensor 201 includes a color mark sensor 2011, which is located above the electrode 4 and is signal-connected to the control module 3.

[0069] In some embodiments, the second sensor 202 includes an encoder 2022 and a code wheel 2021;

[0070] The code wheel 2021 abuts against the electrode 4, so that the electrode 4 drives the code wheel 2021 to rotate;

[0071] The code wheel 2021 is connected to the detection end of the encoder 2022, and the encoder 2022 is connected to the control module 3 via signal.

[0072] Specifically, the pole piece 4 can drive the code wheel 2021 to rotate by moving, and the code wheel 2021 drives the detection end of the encoder 2022 to rotate. Thus, the encoder 2022 can collect the belt travel information of the pole piece 4. For example, the moving distance and moving length of the pole piece 4 can be obtained based on the rotation distance and rotation speed of the detection end of the encoder 2022.

[0073] Simultaneously, the color mark sensor 2011 can collect color information on the surface of the electrode 4 and transmit this color information to the control module 3. The control module 3 determines the single-sided coating area 401 and the double-sided coating area 402 of the electrode 4, as well as the boundary between the single-sided coating area 401 and the double-sided coating area 402, based on the color information. At the same time, it determines the position of the single-sided coating area 401 and the double-sided coating area 402, as well as the boundary between the single-sided coating area 401 and the double-sided coating area 402, based on the moving distance and moving length of the electrode 4 collected by the encoder 2022, to ensure that the roller pressing assembly 1... When the double-sided coating area 402 is rolled to the single-sided coating area 401, the rolling pressure first moves from the position of rolling the electrode 4 to the position of detaching the electrode 4 when passing the junction 403 between the single-sided coating area and the double-sided coating area. Then, it moves from the position of detaching the electrode 4 to the position of rolling the electrode 4. That is, the rolling assembly 1 can skip the junction 403 between the single-sided coating area and the double-sided coating area. This avoids applying excessive rolling pressure to the junction 403 between the single-sided coating area and the double-sided coating area when switching from a small roll gap to a large roll gap, which would cause overpressure at the junction 403 between the single-sided coating area and the double-sided coating area.

[0074] In some embodiments, a first switching point 404 and a second switching point 405 are provided on the electrode 4 at the junction 403 adjacent to the single-sided coating area and the double-sided coating area; such as Figure 1 As shown, in the conveying direction of electrode 4, the first switching point 404 is located downstream of the second switching point 405; when the adjusting roller 102 passes the first switching point 404, the adjusting roller 102 switches from the position of pressing electrode 4 to the position of disengaging electrode 4; when the adjusting roller 102 passes the second switching point 405, the adjusting roller 102 switches from the position of disengaging electrode 4 to the position of pressing electrode 4.

[0075] In other words, when the adjusting roller 102 passes the first switching point 404, the adjusting roller 102 jumps and moves from the position of pressing the electrode 4 to the position of disengaging from the electrode 4. When the adjusting roller 102 passes the second switching point 405, the adjusting roller 102 jumps and moves from the position of disengaging from the electrode 4 to the position of pressing the electrode 4.

[0076] By setting the first switching point 404 and the second switching point 405, the adjusting roller 102 can jump ahead and fall back behind the junction 403 of the single-sided coating area and the double-sided coating area. This ensures that during the movement between the electrode detachment position and the electrode pressing position, the roller is not pressed to switch to the electrode pressing position. This also avoids the problem of overpressure at the junction 403 of the single-sided coating area and the double-sided coating area.

[0077] In some embodiments, the rolling position includes a single-sided rolling position and a double-sided rolling position.

[0078] When the adjusting roller 102 passes through the single-sided coating area 401 of the electrode sheet 4, the adjusting roller 102 is in the single-sided rolling position;

[0079] When the adjusting roller 102 passes through the double-sided coating area 402 of the electrode 4, the adjusting roller 102 is in the double-sided rolling position.

[0080] It is understandable that the thickness of the single-sided coating area 401 and the double-sided coating area 402 of the electrode 4 is different. In other words, the size of the roll gap defined between the adjusting roller 102 and the fixed roller 101 is different. That is to say, when the adjusting roller 102 passes through the single-sided coating area 401 of the electrode 4, the size of the roll gap defined between the adjusting roller 102 and the fixed roller 101 can meet the rolling pressure requirements of the single-sided coating area 401. That is, the position of the adjusting roller 102 at this time is the single-sided rolling pressure position.

[0081] When the adjusting roller 102 passes through the double-sided coating area 402 of the electrode 4, the size of the roller gap between the adjusting roller 102 and the fixed roller 101 can meet the rolling pressure requirements of the double-sided coating area 402. That is, the position of the adjusting roller 102 at this time is the double-sided rolling pressure position.

[0082] In some embodiments, a second detection component 5 is also included, which is located downstream of the roll forming component 1 and is signal-connected to the control module 3.

[0083] The second detection component 5 is used to collect the thickness of the single-sided coating area 401 and the double-sided coating area 402 of the electrode 4 after rolling.

[0084] Optionally, the second detection component 5 can be a thickness gauge to collect the thickness of the single-sided coating area 401 and the double-sided coating area 402 of the electrode 4 after rolling.

[0085] The control module 3 controls the size of the roller gap of the adjusting roller 102 at the position of the rolled electrode 4 based on the relationship between the thickness of the single-sided coating area 401 of the rolled electrode 4 and the preset thickness of the single-sided coating area 401.

[0086] The control module 3 controls the size of the roller gap of the adjusting roller 102 at the position of the roller pressing electrode 4 based on the relationship between the thickness of the double-sided coating area 402 of the rolled electrode 4 and the preset thickness of the double-sided coating area 402.

[0087] It is understandable that the single-sided coating area 401 of the electrode 4 has a preset thickness after rolling. During the actual rolling process, the thickness of the single-sided coating area 401 of the electrode 4 after rolling is collected by a thickness gauge. The control module 3 can control the size of the roller gap of the adjusting roller 102 at the position of rolling the electrode 4 according to the relationship between the thickness of the single-sided coating area 401 of the electrode 4 after rolling collected by the thickness gauge and the preset thickness of the single-sided coating area 401 of the electrode 4 after rolling, so that the thickness of the single-sided coating area 401 of the electrode 4 after rolling is equal to the preset thickness of the single-sided coating area 401 of the electrode 4 after rolling.

[0088] Similarly, the double-sided coating area 402 of the electrode 4 has a preset thickness after rolling. During the actual rolling process, the thickness of the double-sided coating area 402 of the electrode 4 after rolling is collected by a thickness gauge. The control module 3 can control the size of the roller gap of the adjusting roller 102 at the position of rolling the electrode 4 according to the relationship between the thickness of the double-sided coating area 402 of the electrode 4 after rolling collected by the thickness gauge and the preset thickness of the double-sided coating area 402 of the electrode 4 after rolling, so that the thickness of the double-sided coating area 402 of the electrode 4 after rolling is equal to the preset thickness of the double-sided coating area 402 of the electrode 4 after rolling.

[0089] Therefore, the thickness of the single-sided coating area 401 of the rolled electrode 4 and the thickness of the double-sided coating area 402 of the rolled electrode 4 can meet the requirements, reducing errors.

[0090] This utility model also provides an electrode 4.

[0091] The electrode 4 in this embodiment of the present invention is an electrode 4 rolled by the rolling equipment described in the above embodiment.

[0092] In this invention, there is no overvoltage problem at the junction 403 of the single-sided coating area and the double-sided coating area of ​​the electrode 4.

[0093] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
