Description

Technical Field

[0001] The embodiments of the present application relate to the field of blanking technology, and more specifically, the embodiments of the present application relate to a blanking device and a battery cell processing equipment. Background Art

[0002] After the battery cell is wound on the winding needle, the battery cell is unloaded by the unloading device.

[0049] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0050] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0051] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0052] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0053] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0054] In the prior art, after the battery cell is wound on the winding needle, a feeding device is required to clamp and position the battery cell to keep the battery cell in a fixed position so as to facilitate the removal of the winding needle. In the process of the feeding device clamping and positioning the battery cell, the battery cell pole piece may be wrinkled and uneven. In particular, when the winding needle has an asymmetric structure, such as a parallelogram, when the feeding device is used to clamp and position the battery cell, the accuracy of the margin and center distance of the battery cell cannot be guaranteed, which can easily cause the pole piece wrinkling.

[0055] Reference Figure 5 , showing the structure of the battery cell. In the prior art, the feeding device can only move in the vertical direction (i.e. the first direction, which is the thickness direction of the battery cell), and cannot move in the horizontal direction (i.e. the second direction, which is the length direction of the battery cell). Therefore, the shaping of the short side of the battery cell cannot be guaranteed, which makes it easy for the electrode sheets on the battery cell to wrinkle.

[0056] Based on the above technical problems, the present application provides a feeding device. Figure 1-Figure 4 The unloading device includes: a mounting base 1. A driving unit 2, which is arranged on the mounting base 1. A transmission unit 3, which is arranged on the mounting base 1 and connected to the driving unit 2. The transmission unit 3 includes a transmission member 30, a first transmission unit 31 and a second transmission unit 32, wherein the first transmission unit 31 and the second transmission unit 32 respectively cooperate with the transmission member 30; a first clamp 4 and a second clamp 5, wherein the first clamp 4 is fixedly connected to the first transmission unit 31, and the second clamp 5 is fixedly connected to the second transmission unit 32; wherein the driving unit 2 drives the transmission member 30 to move the first clamp 4 and the second clamp 5, and the movement trajectories of the first clamp 4 and the second clamp 5 have movement components in a first direction and movement components in a second direction;

[0057] The first direction is a vertical direction, and the second direction is a horizontal direction.

[0058] In the embodiment of the present application, the unloading device mainly includes a mounting base 1, a driving unit 2, a transmission unit 3, and a first clamping jaw 4 and a second clamping jaw 5 that cooperate with each other.

[0059] The driving unit 2 and the transmission unit 3 are both arranged on the mounting base 1, and the mounting base 1 provides a solid foundation for the entire device to ensure that each component can work stably.

[0060] The driving unit 2 is used as a power source to drive the first clamping jaw 4 and the second clamping jaw 5. The driving unit 2 enables the unloading device to move accurately according to preset requirements. For example, the driving unit 2 can be a motor.

[0061] The transmission unit 3 is mounted on the mounting base 1 and connected to the driving unit 2. The transmission unit 3 is further composed of a transmission member 30, a first transmission unit 31 and a second transmission unit 32. The first transmission unit 31 and the second transmission unit 32 cooperate with the transmission member 30 to ensure effective transmission and conversion of power.

[0062] In addition, the unloading device is also equipped with a first clamping jaw 4 and a second clamping jaw 5. The two clamping jaws are fixedly connected to the first transmission unit 31 and the second transmission unit 32 respectively. Through the drive of the transmission unit 3, the battery cell 100 can be accurately clamped and the battery cell 100 can be flattened and shaped.

[0063] The driving unit 2 can move the first clamp 4 and the second clamp 5 by driving the transmission member 30. The motion trajectory of the first clamp 4 and the second clamp 5 is a composite motion trajectory, which has a motion component in the first direction and a motion direction in the second direction. The first direction is the vertical direction, and the second direction is the horizontal direction. Specifically, in the battery cell structure, the first direction is the thickness direction of the battery cell, and the second direction is the length direction of the battery.

[0064] Specifically, the driving unit 2 can make the first transmission unit 31 and the second transmission unit 32 move on the mounting base 1 by driving the transmission member 30. The first clamp 4 is fixedly connected to the first transmission unit 31. During the movement of the first transmission unit 31 relative to the mounting base 1, the first transmission unit 31 drives the first clamp 4 to generate a composite motion trajectory; the second clamp 5 is fixedly connected to the second transmission unit 32. During the movement of the second transmission unit 32 relative to the mounting base 1, the second transmission unit 32 drives the second clamp 5 to generate a composite motion trajectory. For example, the first clamp 4 and the second clamp 5 move toward or away from each other in the first direction, and the unloading device clamps the battery cell 100. The first clamp 4 and the second clamp 5 reciprocate in the second direction, and the unloading device can shape the short side of the battery cell 100.

[0065] Therefore, in an embodiment of the present application, a material unloading device is provided, which drives the transmission member 30 through the driving unit 2 so that the first clamp 4 and the second clamp 5 can generate a motion trajectory having a motion component in a first direction and a motion component in a second direction, so that the first clamp 4 and the second clamp 5 cooperate with each other in the first direction to flatten the battery cell 100, and the first clamp 4 and the second clamp 5 cooperate with each other in the second direction to shape (for example, flatten) the battery cell 100, thereby avoiding wrinkles in the battery cell 100 when clamped.

[0066] In one embodiment, referring to Figure 2-Figure 4 , the first transmission unit 31 includes a first guide member 311 and a first moving block 312, and the first guide member 311 and the first moving block 312 are fixedly connected;

[0067] The first guide member 311 is movably disposed on the mounting seat 1 , and a moving track of the first guide member 311 has a guiding component in the first direction and a guiding component in the second direction.

[0068] In this embodiment, the first transmission unit 31 is mainly composed of a first guide member 311 and a first moving block 312, which are fixedly connected, which means that when the first guide member 311 moves, the first moving block 312 will also move accordingly.

[0069] The first guide member 311 is movably disposed on the mounting seat 1, wherein the first guide member 311 has guide components in both the first direction and the second direction. That is, when the transmission member 30 drives the first guide member 311 to move, the first guide member 311 moves on the mounting seat, and the movement trajectory of the first guide member 311 has guide components in the first direction and the second direction.

[0070] Since the first guide 311 and the first moving block 312 are fixedly connected, the motion trajectory of the first moving block 312 can also generate motion components in the first direction and the second direction. Further, since the first clamp 4 is fixedly connected to the first transmission unit 31, the motion trajectory of the first clamp 4 can also generate motion components in the first direction and the second direction. For example, the first clamp 4 can be fixedly connected to the first guide 311, or the first clamp 4 can be fixedly connected to the first moving block 312.

[0071] Therefore, in this embodiment, the first clamp 4 can obtain precise and coordinated movement in two directions at the same time. The first clamp 4 can move along the first direction to flatten the battery cell 100, and the first clamp 4 can move along the second direction to shape the battery cell 100.

[0072] In one embodiment, referring to Figure 2-Figure 4 , the second transmission unit 32 includes a second guide member 321 and a second moving block 322, and the second guide member 321 and the second moving block 322 are fixedly connected;

[0073] The second guide member 321 is movably disposed on the mounting seat, and a moving track of the second guide member 321 has a guiding component in the first direction and a guiding component in the second direction.

[0074] In this embodiment, the second transmission unit 32 is mainly composed of a second guide member 321 and a second moving block 322, and the two are fixedly connected, which means that when the second guide member 321 moves, the second moving block 322 will also move accordingly.

[0075] The second guide member 321 is movably disposed on the mounting seat 1, and the second guide member 321 has a guiding component in both the first direction and the second direction. That is, when the transmission member 30 drives the second guide member 321 to move, the second guide member 321 moves on the mounting seat, and the second guide member 321 has a guiding component in both the first direction and the second direction.

[0076] Since the second guide 321 and the second moving block 322 are fixedly connected, the motion trajectory of the second moving block 322 can also generate motion components in the first direction and the second direction. Further, since the second clamping jaw 5 is fixedly connected to the second transmission unit 32, the motion trajectory of the second clamping jaw 5 can also generate motion components in the first direction and the second direction. For example, the second clamping jaw 5 can be fixedly connected to the second guide 321, or the second clamping jaw 5 can be fixedly connected to the second moving block 322.

[0077] Therefore, in this embodiment, the second clamping jaw 5 can obtain precise and coordinated movement in two directions at the same time. The second clamping jaw 5 can move along the first direction to flatten the battery cell, and the second clamping jaw 5 can move along the second direction to shape the battery cell 100.

[0078] In this embodiment, the second transmission unit 32 includes a second guide member 321 and a second moving block 322 . The second guide member 321 and the second moving block 322 are fixedly connected, and the second guide member 321 is movably disposed on the mounting seat 1 .

[0079] Specifically, refer to Figure 1-Figure 4 The first guide member 311 and the second guide member 321 are located on opposite sides of the transmission member 30 .

[0080] In this embodiment, the first guide member 311 is located on the first side of the transmission member 30, and the second guide member 321 is located on the second side of the transmission member 30, and the first side and the second side are arranged opposite to each other. This layout enables the transmission member 30 to interact with the two guide members at the same time, thereby driving them to move in a predetermined direction. Such a design not only improves the compactness of the overall mechanism, but also helps to ensure that the movement of the two guide members is synchronized and coordinated.

[0081] In a specific embodiment, referring to Figure 4 and Figure 5 The first guide member 311 is located on the left side of the transmission member 30, and the second guide member 321 is located on the right side of the transmission member 30. The transmission member 30 is placed between the first guide member 311 and the second guide member 321. The transmission member 30 drives the first guide member 311 and the second guide member 321 to move at the same time.

[0082] In one embodiment, referring to Figure 2-Figure 5The first moving block 312 and the second moving block 322 are located on opposite sides of the transmission member 30 .

[0083] In this embodiment, the first moving block 312 is located on the third side of the transmission member 30, and the second moving block 322 is located on the fourth side of the transmission member 30, and the third side and the fourth side are arranged opposite to each other. In this way, the space of the mounting seat is utilized to reasonably arrange the first guide member 311, the transmission member 30, the second guide member 321, the first moving block 312 and the second moving block 322. This layout helps to optimize the space occupied by the entire mechanism and makes the unloading device more compact.

[0084] In a specific embodiment, referring to Figure 3 , the first moving block 312 is located at the lower side of the transmission member 30, and the second moving block 322 is located at the upper side of the transmission member 30. And refer to Figure 1-Figure 3 In a specific embodiment, the first clamping jaw 4 is fixedly connected to the first moving block 312, and the second clamping jaw 5 is fixedly connected to the second moving block 322, so that the second clamping jaw 5 is located above the first clamping jaw 4. When the driving unit 2 drives the transmission member 30 to move the first clamping jaw 4 and the second clamping jaw 5, the first clamping jaw 4 and the second clamping jaw 5 can move relative to or opposite to each other in the first direction to achieve the flattening of the battery cell 100; and the first clamping jaw 4 and the second clamping jaw 5 can reciprocate in the second direction to achieve the shaping of the short side of the battery cell 100, thereby avoiding the wrinkling of the battery cell electrode sheet.

[0085] In a specific embodiment, referring to Figure 3 , the first moving block 312 is located at the lower side of the transmission member 30, the second moving block 322 is located at the upper side of the transmission member 30, the first guide member 311 is fixedly connected to the first moving block 312, the second moving block 322 is provided with a through hole, the first guide member 311 passes through the through hole and is slidably arranged relative to the second moving block 322, when the first guide member 311 drives the first moving block 312 to move synchronously, the first guide member 311 slides relative to the second moving block 322. Similarly, the second guide member 321 is fixedly connected to the second moving block 322, the first moving block 312 is provided with a through hole, the second guide member 321 passes through the through hole and is slidably arranged relative to the first moving block 312, when the second guide member 321 drives the second moving block 322 to move synchronously, the second guide member 321 slides relative to the first moving block 312.

[0086] In one embodiment, referring to Figure 1-Figure 4 The transmission member 30 is a transmission gear, the first guide member 311 is a first rack, and the second guide member 321 is a second rack.

[0087] In this embodiment, the transmission member 30 is designed as a transmission gear. The transmission gear is a common transmission element, and power and torque can be transmitted through its rotational motion. The first guide member 311 is a first rack, and the second guide member 321 is a second rack. A rack is a bar-shaped element with continuous teeth, which can be used in conjunction with a gear. When the transmission gear is meshed with the rack, the rotational motion of the gear is converted into the linear motion of the rack. Therefore, in this embodiment, the first rack and the second rack serve as guide members of the first transmission unit 31 and the second transmission unit 32, respectively, and realize linear motion by meshing with the transmission gears.

[0088] It should be noted that the transmission member includes but is not limited to a gear structure, and the guide member includes but is not limited to a rack structure. For example, the transmission unit may include a helical gear transmission structure, a helical lever connecting rod structure, an inclined plane structure, and the like.

[0089] In one embodiment, referring to Figure 3 The mounting seat 1 includes a mounting seat body 10, a first linear rail 11 and a second linear rail 12, wherein the first linear rail 11 and the second linear rail 12 are arranged on the mounting seat body 10, and the first linear rail 11 and the second linear rail 12 are inclined relative to the first direction and the second direction;

[0090] The first transmission unit 31 is slidably disposed on the first linear rail 11 and the second linear rail 12 , and the second transmission unit 32 is slidably disposed on the first linear rail 11 and the second linear rail 12 .

[0091] In this embodiment, the design of the mounting seat 1 provides a stable and precise motion guide for the unloading device. The mounting seat 1 includes a mounting seat body 10, a first linear rail 11 and a second linear rail 12, both of which are arranged on the mounting seat 1. Specifically, the first linear rail 11 and the second linear rail 12 are fixed on the mounting seat 1. This design allows the clamping jaw drive mechanism to achieve precise motion in two different directions.

[0092] The first transmission unit 31 and the second transmission unit 32 are both designed to be slidably disposed on the first linear rail 11 and the second linear rail 12. Specifically, the first moving block 312 in the first transmission unit 31 is slidably disposed on the first linear rail 11 and the second linear rail 12, and the second moving block 322 in the second transmission unit 32 is slidably disposed on the first linear rail 11 and the second linear rail 12, which means that the two transmission units 3 can slide along the two linear rails, thereby achieving precise movement of the clamping jaws.

[0093] Since the first linear rail 11 and the second linear rail 12 are both inclined relative to the first direction (vertical direction) and the second direction (horizontal direction), the transmission unit 3 can move on a composite path instead of just moving along a straight line or a single direction. Since the transmission unit 3 can move on the composite path, the clamping claw fixedly connected to the transmission unit 3 can also move on the composite path formed by the first direction and the second direction, so as to realize the flattening and shaping (leveling) operation of the battery cell 100.

[0094] In a specific embodiment, referring to Figure 4 The first guide member 311 is sleeved with a first connecting portion 313 , and the first guide member 311 is fixedly connected to the first moving block 312 via the first connecting portion 313 .

[0095] In this embodiment, the first guide member 311 is sleeved with a first connecting portion 313, which acts as a bridge to firmly fix the first guide member 311 and the first moving block 312. Optionally, the first connecting portion 313 may be a connecting block structure.

[0096] In a specific embodiment, referring to Figure 3 The second guide member 321 is sleeved with a second connecting portion 323 , and the second guide member 321 is fixedly connected to the second moving block 322 via the second connecting portion 323 .

[0097] In this embodiment, the second guide member 321 is sleeved with a second connecting portion 323, and the second connecting portion 323 is used to firmly fix the second guide member 321 and the second moving block 322. Optionally, the second connecting portion 323 can be a connecting block structure.

[0098] In one embodiment, referring to Figure 2 and Figure 3 The first clamping jaw 4 is provided with a first adsorption hole 41, and / or the second clamping jaw 5 is provided with a second adsorption hole 51, and the axes of the first adsorption hole 41 and the second adsorption hole 51 extend along the first direction.

[0099] In this embodiment, a first adsorption hole 41 is provided on the first clamping jaw 4 and a second adsorption hole 51 is provided on the second clamping jaw 5. When the unloading device clamps and fixes the battery cell 100, the first adsorption hole 41 and the second adsorption hole 51 respectively adsorb the battery cell 100 to facilitate the removal of the winding needle 200.

[0100] Specifically, the transmission member 30 of the driving unit 2 makes the first clamp 4 and the second clamp 5 close to the battery cell 100, the first clamp 4 and the second clamp 5 slightly clamp the battery cell 100 and cooperate with the adsorption holes to adsorb the battery cell 100 (clamp the battery cell 100 before pulling out the needle, no need to use too much force, just keep the battery cell 100 in place), the first adsorption hole 41 on the first clamp 4 and the second adsorption hole 51 on the second clamp 5 respectively adsorb the battery cell 100, at this time the winding needle 200 withdraws the needle, so that the winding needle 200 is separated from the battery cell 100.

[0101] In one embodiment, referring to Figure 1 , the unloading device further comprises a support 6 and a moving component 7, the mounting seat 1 is fixed on the support 6, and the support 6 is arranged on the moving component 7;

[0102] The moving component 7 can drive the mounting seat 1 to move along the first direction and / or the second direction and / or the third direction, and the moving component 7 can drive the mounting seat 1 to rotate around a third direction, wherein the third direction is perpendicular to the first direction and the second direction.

[0103] In this embodiment, the mounting base 1 is fixed on the support 6, which means that the entire material discharging device has a stable support point, which helps to ensure the stability and reliability of the entire material discharging device when working.

[0104] The support 6 is arranged on the moving part 7, so that the entire mounting base 1 and the clamping mechanism thereon can be moved and rotated through the moving part 7. This design greatly increases the range of motion and flexibility of the blanking device.

[0105] The moving component 7 has multiple movement capabilities. For example, the moving component 7 is a multi-axis movement mechanism. The moving component 7 can drive the mounting seat 1 to move along the first direction and / or the second direction and / or the third direction, and the moving component 7 can also drive the mounting seat 1 to rotate around the third direction, so that the unloading device can better adapt to the battery cells of different positions, shapes and sizes, and achieve more accurate positioning and placement.
