Description

Technical Field

[0001] This utility model relates to the field of electrode processing, and in particular to an electrode correction device. Background Technology

[0002] For button cell electrode winding, the existing electrode winding correction methods are mostly electrode swing correction or electrode clamping correction. Due to the narrow width of button cells and the high dimensional accuracy of the positive and negative electrode covering, the swing correction structure occupies too much space for the electrode correction mechanism of the existing button cell winding equipment and cannot be installed at the winding end. Moreover, the length of button cells is usually short, so the correction effect has little impact on the electrode accuracy at the winding point.

[0003] Most existing button cell winding equipment uses clamping-type electrode correction. While clamping-type correction solves the drawbacks of swing-type correction, such as large space occupation and distance from the winding point, there is still a certain spatial distance between clamping-type correction and the winding point due to structural layout. Furthermore, the principle of clamping-type correction is that the correction detection photoelectric sensor detects electrode misalignment and then sends a feedback signal to the correction mechanism. Therefore, the correction structure has a delayed response time, which makes it impossible to achieve high precision in the winding and covering dimensions of button cells. When electrode misalignment occurs, on-site production personnel often need to spend a certain amount of time and effort to recalibrate the correction mechanism, which greatly affects on-site production efficiency. Summary of the Invention

[0004] To improve the convenience of electrode correction and enhance the adaptability of the correction device, this utility model provides an electrode correction device.

[0005] This utility model provides a technical solution that adopts the following approach:

[0006] An electrode correction device, comprising:

[0007] frame;

[0008] X-axis drive assembly, which drives the clamping part to move along the X-axis, includes an X-axis electric drive component and an X-axis manual drive component;

[0009] The X-axis drive group and the Y-axis drive group are mounted on the frame;

[0010] The clamping assembly includes a first clamping part, a second clamping part, and a clamping drive member, wherein the clamping drive member drives the first clamping part and the second clamping part to move together to a state of clamping both sides of the electrode sheet;

[0011] The Y-axis drive assembly drives the clamping part to move along the Y-axis. The Y-axis drive assembly includes a Y-axis electric drive component and a Y-axis manual drive component.

[0012] With the X and Y axes in a mutually perpendicular state on different planes, the X-axis electric drive and the Y-axis electric drive are activated sequentially, driving the clamping assembly to move along the X and Y axes. This causes the clamping assembly to approach the electrode sheet until the first and second clamping parts of the clamping assembly are located on both sides of the electrode sheet. Then, the clamping assembly drives the first and second clamping parts to move towards the state of clamping the electrode sheet, making it easier to wind the electrode sheet. At the same time, the correction device has the advantages of both automated high efficiency and manual fine adjustment, which helps to improve the accuracy and flexibility of correction during winding. This improves the accuracy and alignment of the small cell electrode sheet winding and forming, ensures the chip winding insertion accuracy, and thus improves the overall production quality of the battery cell.

[0013] Preferably, the X-axis electric drive unit includes a first slide rail and a first slide plate, the first slide plate being slidably connected to the first slide rail, the length direction of the first slide rail extending along the X-axis, the Y-axis drive assembly being disposed on the first slide plate, and the clamping assembly being disposed on the Y-axis drive assembly.

[0014] The first slide plate and the first slide rail work together to drive the Y-axis drive group. The X-axis drive group, the Y-axis drive group, and the clamping group are connected in sequence. The X-axis drive group indirectly applies force to the clamping group by driving the Y-axis drive group. This simplifies the overall structure of the device, avoids overly complex structures connected to the clamping group, and improves the rationality of the overall structural design. The X-axis drive group is positioned so that the clamping part is close to the electrode in the X-axis direction.

[0015] Preferably, the Y-axis drive assembly is located at the end of the first slide plate, the length of the first slide plate is not less than two-thirds of the length of the first slide rail, and the first slide plate has a first locking strip on one side along its own thickness direction for engaging with the slide rail, the length of the first locking strip being the same as the length of the first slide plate.

[0016] Since the Y-axis drive assembly is located on the first slide plate, and the first slide plate supports part of the weight of the Y-axis drive assembly, the connection area between the first slide plate and the first slide rail is lengthened, making the connection between the first slide plate and the first slide rail tighter. This makes it less likely for the first slide plate to separate from the first slide rail due to excessive force on its own part, which helps to improve the stability of the X-axis drive assembly.

[0017] Preferably, a steering plate is fixedly connected to the end of the first slide plate, the steering plate is set perpendicular to the first slide plate, a second slide rail is provided on the side of the steering plate away from the first slide plate, the Y-axis electric drive unit includes a second slide plate that slides on the second slide rail, the second slide plate is provided with a base, and the clamping assembly is provided on the base.

[0018] The second slide rail and the second slide plate on the steering plate work together to drive the clamping assembly to move along the Y-axis. The steering plate design facilitates the modularization of multiple components, making subsequent maintenance and repair easier.

[0019] Preferably, the X-axis manual drive component includes a first drive column and a micrometer sleeved on the outer wall of the first drive column. The first drive column is connected to the first slide plate and drives the first slide plate to slide.

[0020] A micrometer is connected to the first drive column. When the X-axis electric drive component is damaged and the worker needs to manually adjust the machine, the machine can be manually adjusted to a more precise position, which helps to improve the accuracy of correction, further improve the alignment of the electrode winding and the quality of the battery cell, and increase the yield.

[0021] The connection between the first drive column and the first slide can be such that the end of the first drive column directly abuts against a portion of the first slide, and the first slide can be driven to move by pushing the first drive column; alternatively, the first drive column can be set as a lead screw, and a slider threadedly connected to it can be set on the first slide, and the first slide can be driven to move by rotating the first drive column.

[0022] Preferably, the Y-axis manual drive component includes a second drive column and a micrometer sleeved on the outer wall of the second drive column. The second drive column is connected to the second slide plate and drives the second slide plate to slide.

[0023] The connection between the second drive column and the second slide can be such that the end of the second drive column directly abuts against a portion of the second slide, and the second slide can be driven to move by pushing the second drive column; alternatively, the second drive column can be set as a lead screw, and a slider threadedly connected to it can be set on the second slide, and the second slide can be driven to move by rotating the second drive column.

[0024] Preferably, the first clamping part and the second clamping part can slide towards each other. The clamping assembly includes a base plate and a pneumatic finger. The base plate is disposed on the bottom side of the pneumatic finger along the height direction. The cylinder of the pneumatic finger is disposed on the base plate. The first clamping part and the second clamping part are respectively connected to the ends of the two mechanical fingers of the pneumatic finger.

[0025] Once either the first or second clamping part contacts the side of the electrode, both continue to move, pushing the electrode to the other clamping part, causing the other side of the electrode to contact the other clamping part. The first and second clamping parts then contact opposite sides of the electrode. Using pneumatic fingers to drive the first and second clamping parts helps to correct the electrode's contact and alignment, thus protecting the electrode.

[0026] Preferably, both the first clamping part and the second clamping part can be detachably disposed at the end of the pneumatic finger.

[0027] When the specifications of the electrode plates are different, and the first clamping part and the second clamping part need to be replaced, the first clamping part and the second clamping part can be removed and replaced, which helps to improve the adaptability of the overall device.

[0028] Preferably, the X-axis manual drive component includes a connecting block fixedly connected to the frame, the connecting block having internal threads and a third drive column threadedly connected thereto, the X-axis manual drive component also including a micrometer sleeved on the outer wall of the third drive column, the third drive column being rotatably connected to an abutment block, the abutment block abutting against the Y-axis drive assembly.

[0029] Preferably, the clamping assembly includes a clamping cylinder and a push block disposed on the base. The push block is provided with a push plate groove. The push block is a rectangular block. The push block forms a push plate groove for pushing the electrode sheet into by opening along one diagonal towards the other diagonal. A first clamping part and a second clamping part are formed on both sides of the push plate groove. The first clamping part and the second clamping part are in a state where they cannot move relative to each other.

[0030] In other embodiments, the first clamping part and the second clamping part may be in a relatively fixed state to reduce the possibility of the first clamping part and the second clamping part damaging the electrode.

[0031] In summary, this utility model has the following beneficial technical effects:

[0032] When the X-axis and Y-axis are perpendicular to each other on different planes, the X-axis electric drive and the Y-axis electric drive are activated sequentially, driving the clamping assembly to move along the X-axis and Y-axis, bringing the clamping assembly closer to the electrode sheet until the first and second clamping parts of the clamping assembly are located on both sides of the electrode sheet. Then, the clamping assembly drives the first and second clamping parts to move toward the state of clamping the electrode sheet, making it easier to wind the electrode sheet. At the same time, the correction device has the advantages of automated high efficiency and manual fine adjustment, which helps to improve the accuracy and flexibility of correction during winding.

[0036] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0037] This utility model discloses an electrode correction device.

[0038] Reference Figure 1 An electrode correction device, comprising:

[0039] frame;

[0040] X-axis drive assembly, which drives the clamping part to move along the X-axis, includes an X-axis electric drive component and an X-axis manual drive component;

[0041] The X-axis drive group and the Y-axis drive group are mounted on the frame;

[0042] The clamping assembly includes a first clamping part 16, a second clamping part 17, and a clamping drive member, wherein the clamping drive member drives the first clamping part 16 and the second clamping part 17 to move together to the state of clamping both sides of the electrode sheet.

[0043] The Y-axis drive assembly drives the clamping part to move along the Y-axis. The Y-axis drive assembly includes a Y-axis electric drive component and a Y-axis manual drive component.

[0044] When the X-axis and Y-axis are perpendicular to each other on different planes, the X-axis electric drive and the Y-axis electric drive are activated sequentially, driving the clamping assembly to move along the X-axis and Y-axis, bringing the clamping assembly closer to the electrode sheet until the first clamping part 16 and the second clamping part 17 of the clamping assembly are located on both sides of the electrode sheet. Then, the clamping assembly drives the first clamping part 16 and the second clamping part 17 to move toward the state of clamping the electrode sheet, making it easier to wind the electrode sheet. At the same time, the correction device has the advantages of automated high efficiency and manual fine adjustment, which helps to improve the accuracy and flexibility of correction during winding, thereby improving the accuracy and alignment of the small cell electrode sheet winding and forming, ensuring the chip winding insertion accuracy, and thus improving the overall production quality of the cell.

[0045] Reference Figure 1 In this embodiment, the X-axis electric drive unit includes a first slide rail 1 and a first slide plate 2. The first slide plate 2 is slidably connected to the first slide rail 1. The length direction of the first slide rail 1 extends along the X-axis. The Y-axis drive group is disposed on the first slide plate 2, and the clamping group is disposed on the Y-axis drive group.

[0046] The first slide plate 2 cooperates with the first slide rail 1 to drive the Y-axis drive group. The X-axis drive group, the Y-axis drive group and the clamping group are connected in sequence. The X-axis drive group indirectly applies force to the clamping group by driving the Y-axis drive group, which helps to simplify the structure of the overall device, avoids the structure connected to the clamping group being too complicated, and helps to improve the rationality of the overall structure. The setting of the X-axis drive group makes the clamping part close to the electrode in the X-axis direction.

[0047] The first slide rail 1 is electrically driven by a cylinder.

[0048] Reference Figure 1 In this embodiment, the Y-axis drive group is located at the end of the first slide plate 2. The length of the first slide plate 2 is not less than two-thirds of the length of the first slide rail 1. The first slide plate 2 has a first locking strip on one side along its own thickness direction for locking into the slide rail. The length of the first locking strip is the same as the length of the first slide plate 2.

[0049] Since the Y-axis drive assembly is located on the first slide plate 2, and the first slide plate 2 supports part of the weight of the Y-axis drive assembly, the connection area between the first slide plate 2 and the first slide rail 1 is lengthened, making the connection between the first slide plate 2 and the first slide rail 1 tighter. This makes it less likely that the first slide plate 2 will separate from the first slide rail 1 due to excessive force on its own part, which is beneficial to improving the stability of the X-axis drive assembly.

[0050] Reference Figure 1 In this embodiment, a steering plate 3 is fixedly connected to the end of the first slide plate 2. The steering plate 3 is set perpendicular to the first slide plate 2. A second slide rail 4 is provided on the side of the steering plate 3 away from the first slide plate 2. The Y-axis electric drive unit includes a second slide plate 5 that slides on the second slide rail 4. The second slide plate 5 is provided with a base 6, and a clamping assembly is provided on the base 6.

[0051] The second slide rail 4 and the second slide plate 5, mounted on the steering plate 3, work together to drive the clamping assembly to move along the Y-axis. The steering plate 3 facilitates the modularization of multiple components, making subsequent maintenance and repair easier. The second slide plate 5 is driven by a cylinder.

[0052] Reference Figure 1 In this embodiment, the X-axis manual drive component includes a first drive column 7 and a micrometer 8 sleeved on the outer wall of the first drive column 7. The first drive column 7 is connected to the first slide plate 2 and drives the first slide plate 2 to slide.

[0053] A micrometer 8 is connected to the first drive column 7. When the X-axis electric drive component is damaged and the worker needs to manually adjust the machine, the machine can be manually adjusted to a more precise position, which helps to improve the accuracy of the correction.

[0054] The connection between the first drive column 7 and the first slide plate 2 can be such that the end of the first drive column 7 directly abuts against a portion of the first slide plate 2, and the first slide plate 2 can be driven to move by pushing the first drive column 7 during driving; or the first drive column 7 can be set as a lead screw, and a slider threadedly connected to it can be set on the first slide plate 2, and the first slide plate 2 can be driven to move by rotating the first drive column 7.

[0055] Reference Figure 1 In this embodiment, the Y-axis manual drive component includes a second drive column and a micrometer 8 sleeved on the outer wall of the second drive column. The second drive column is connected to the second slide plate 5 and drives the second slide plate 5 to slide.

[0056] The connection between the second drive column and the second slide plate 5 can be such that the end of the second drive column directly abuts against a portion of the second slide plate 5, and the second slide plate 5 can be driven to move by pushing the second drive column during driving; alternatively, the second drive column can be set as a lead screw, and a slider threadedly connected to it can be set on the second slide plate 5, and the second slide plate 5 can be driven to move by rotating the second drive column.

[0057] Reference Figure 1 In this embodiment, the first clamping part 16 and the second clamping part 17 can slide toward each other. The clamping assembly includes a base plate 10 and a pneumatic finger 9. The base plate 10 is disposed on the bottom side of the pneumatic finger 9 along the height direction. The cylinder of the pneumatic finger 9 is disposed on the base plate 10. The first clamping part 16 and the second clamping part 17 are respectively connected to the ends of the two mechanical fingers of the pneumatic finger 9.

[0058] Once either the first clamping part 16 or the second clamping part 17 comes into contact with the side of the electrode, both continue to move, pushing the electrode to the other clamping part, so that the other side of the electrode comes into contact with the other clamping part. The first clamping part 16 and the second clamping part 17 respectively abut against the opposite sides of the electrode. Using the pneumatic finger 9 to drive the first clamping part 16 and the second clamping part 17 helps to correct the electrode's contact and alignment, thus protecting the electrode.

[0059] Both the first clamping part 16 and the second clamping part 17 have hollow and concentrically arranged guide parts 18 at their bottoms. Guide posts 19 are inserted into both guide parts 18, making the sliding between the first clamping part 16 and the second clamping part 17 more stable.

[0060] Reference Figure 1 In this embodiment, both the first clamping part 16 and the second clamping part 17 can be detachably disposed at the end of the pneumatic finger 9.

[0061] When the specifications of the electrode plates differ, requiring the replacement of the first clamping part 16 and the second clamping part 17, the first clamping part 16 and the second clamping part 17 can be removed and replaced, which improves the adaptability of the overall device. The connection between the first clamping part 16 and the pneumatic finger 9 can be either a snap-fit ​​connection or a bolt connection. Example

The push block 14 is a rectangular block. The push block 14 forms a push plate groove 15 for pushing the electrode sheet into by opening along one of its diagonals toward the other diagonal. A first clamping part 16 and a second clamping part 17 are formed on both sides of the push plate groove 15. The first clamping part 16 and the second clamping part 17 are in a state where they cannot move relative to each other.
