Description

This method cannot accurately control the local thickness and carries the risk of damaging the electrode sheet surface. At the same time, overall roller pressing cannot accurately control the local pressure, which carries the risk of roller pressing cracks. Utility Model Content

[0062] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0063] Reference Figures 1-3 , Figure 5 A device for precisely leveling the thickness of electrode tabs includes a mounting frame 1, a roller 2, a mounting frame 3, a pressure roller mechanism 4, a pressure roller lifting drive mechanism 5, and a pressure roller leveling mechanism 6.

[0064] The roller 2 is rotatably mounted on the mounting frame 1;

[0065] The mounting frame 3 is slidably disposed on the mounting bracket 1;

[0066] The pressure roller mechanism 4 and the pressure roller lifting drive mechanism 5 are mounted on the mounting frame 3;

[0067] The pressure roller mechanism 4 is used to cooperate with the roller 2 to press the electrode tabs, the pressure roller horizontal adjustment mechanism 6 is used to adjust the position of the pressure roller mechanism 4 along the axial direction of the roller 2, and the pressure roller lifting drive mechanism 5 is used to adjust the distance between the pressure roller mechanism 4 and the roller 2 along the radial direction of the roller 2.

[0068] Roller 2 is rotatably mounted on mounting frame 1. Mounting frame 3, which is equipped with pressure roller mechanism 4 and pressure roller lifting drive mechanism 5, is slidably mounted on mounting frame. Before rolling flat the electrode tab, the electrode sheet is guided between pressure roller mechanism 4 and roller 2. Pressure roller leveling mechanism 6 is used to adjust pressure roller mechanism to be directly above electrode tab. Pressure roller lifting drive mechanism 5 is used to adjust the distance between pressure roller mechanism 4 and roller 2, thereby controlling the thickness of the rolled electrode tab. It can be seen that this embodiment uses a local rolling method to roll the electrode tab, only working on the electrode tab position that needs rolling, avoiding scratches on the electrode sheet surface caused by overall rolling. The thickness accuracy control at the rolling point is relatively easy, and the thickness accuracy at the rolling point can be controlled within 0.005mm.

[0069] Reference Figure 1 Specifically, part of the mounting frame 1 is rotatably connected to the roller 2, and the other part is slidably mounted on the mounting frame 3.

[0070] Reference Figure 2 as well as Figure 8 In one embodiment, the pressure roller lifting drive mechanism 5 includes a first lifting group 52 and an adjustment component 51. The first lifting group 52 includes a mounting bracket 521 and a lifting drive component 522.

[0071] The fixed end of the lifting drive component 522 is mounted on the mounting frame 3, and the output end of the lifting drive component 522 is connected to the mounting bracket 521 for transmission. The pressure roller mechanism 4 is located on the mounting bracket 521. The structure is simple and easy to implement.

[0072] The lifting drive component 522 drives the mounting bracket 521 to rise, which in turn lifts the pressure roller mechanism 4, making it easier to guide the belt between the roller 2 and the pressure roller mechanism 4.

[0073] The lifting drive component 522 can be used to distinguish between working and non-working states. When the device is not in operation, the lifting drive component 522 retracts, and the pressure roller mechanism 4 and roller 2 maintain a certain distance, which facilitates the traction of the material belt or other adjustments. At the same time, it avoids mutual wear between roller 2 and pressure roller mechanism 4 when the device is not in operation, thus preventing a reduction in the service life of the device.

[0074] Reference Figure 3 as well as Figure 8 Specifically, the first lifting assembly 52 further includes a force sensor 523 and a control valve. The force sensor 523 is located between the mounting bracket 521 and the lifting drive component 522. The control valve is communicatively connected to the force sensor 523 and to the lifting drive component 522.

[0075] The force sensor 523 is used to sense the pressure applied by the pressure roller mechanism 4 towards the roller 2. The control valve is used to receive the signal sent by the force sensor 523 and send the signal to the lifting drive 522 to control the operation of the lifting drive 522, so as to achieve precise control of the roller pressure and avoid excessive pressure that could cause the roller to crack.

[0076] Reference Figure 5 as well as Figure 8 Specifically, the mounting bracket 521 includes a first mounting plate 5211, a second mounting plate 5212, and a third mounting plate 5213. The second mounting plate 5212 and the third mounting plate 5213 are vertically connected to the first mounting plate 5211. The output end of the lifting drive component 522 is connected to the first mounting plate 5211 in a transmission manner. The two ends of the pressure roller mechanism 4 are rotatably connected to the second mounting plate 5212 and the third mounting plate 5213, respectively.

[0077] Refer to 5. Figure 6 as well as Figure 7 Specifically, the adjustment component 51 includes a bracket 511, a first fixing block 512, a second fixing block 513, a fine-tuning screw 514, a fine-tuning screw nut 515, an upper wedge block 516, and a lower wedge block 517.

[0078] The bracket 511 is fixed to the mounting frame 3 and is located in the space between the mounting bracket 521 and the pressure roller mechanism 4;

[0079] The first fixing block 512 and the second fixing block 513 are fixedly installed on the bracket 511;

[0080] The fine-tuning screw 514 is rotatably connected to the first fixing block 512 and the second fixing block 513. The fine-tuning screw nut 515 is threadedly connected to the fine-tuning screw 514. The lower wedge block 517 is fixedly connected to the fine-tuning screw nut 515 and the bottom of the lower wedge block 517 slides against the bracket 511. The top of the lower wedge block 517 is inclined.

[0081] The upper wedge 516 is fixed on the mounting bracket 521, and the upper wedge 516 is disposed on the side of the mounting bracket 521 facing the lower wedge 517, and the bottom of the upper wedge 516 is inclined.

[0082] The upper wedge 516 and the lower wedge 517 have the same slope, and the slope of the upper wedge 516 is 1:10 to 1:40.

[0083] The adjustment component 51 allows for a small adjustment of the height of the adjustment roller mechanism 4, further adjusting the distance between the roller 2 and the pressure roller mechanism 4, precisely controlling the thickness of the electrode tabs during roller pressing, improving the control over the accuracy of the electrode tab roller pressing, and ensuring processing accuracy.

[0084] After the pressure roller mechanism 4 is coarsely adjusted by the first lifting group 52, the distance between the upper wedge block 516 and the lower wedge block 517 decreases, and the upper wedge block 516 and the lower wedge block 517 even come into contact. The working principle of the first lifting group 52 is as follows: when the fine adjustment screw 514 is rotated, the fine adjustment screw nut 515 moves accordingly. Since the bottom of the lower wedge block 517 slides against the bracket 511, rotating the fine adjustment screw 514 will drive the fine adjustment screw nut 515 to move in a straight line. During the movement of the fine adjustment screw nut 515, the lower wedge block 517 lifts the upper wedge block 516. Since the lower wedge block 517 is fixed on the mounting bracket 521, and the mounting bracket 521 is connected to the pressure roller mechanism 4, it indirectly lifts the pressure roller mechanism 4, thereby achieving fine adjustment of the height of the pressure roller mechanism 4.

[0085] The slope ratios of the upper wedge 516 and the lower wedge 517 are 1:10 to 1:40. Taking a slope ratio of 1:20 as an example, rotating the fine-tuning screw 514 can drive the lower wedge 517 to move a distance of 1mm, thereby driving the lower wedge 517 to lift the upper wedge 516 by 0.005mm, which in turn drives the pressure roller mechanism 4 to lift by 0.005mm.

[0086] It can achieve the adjustment accuracy of lifting the upper wedge block 516 and the pressure roller mechanism 4 by 1mm when the lower wedge block 517 moves by 10mm-20mm, and is easy to operate.

[0087] Specifically, the slope of the upper wedge 516 and the lower wedge 517 is 1:40, which can lift the upper wedge 516 and the pressure roller mechanism 4 by 1mm when the lower wedge 517 moves 20mm.

[0088] It is understandable that the bracket 511 is located within the space enclosed by the first mounting plate 5211, the second mounting plate 5212, the third mounting plate 5213 and the pressure roller mechanism 4.

[0089] Reference Figure 7 Specifically, the adjustment assembly 51 further includes a fine-tuning locking member mounting base 504 and a fine-tuning locking member 505. The fine-tuning locking member mounting base 504 is fixedly connected to the first fixing block 512, and the fine-tuning locking member mounting base 504 is rotatably connected to the fine-tuning screw 514. The fine-tuning locking member 505 is disposed on the fine-tuning locking member mounting base 504, and the fine-tuning locking member mounting base 504 is used to restrict the rotation of the fine-tuning screw 514.

[0090] Reference Figure 7 Specifically, a fine-tuning handwheel 506 is fixed to one end of the fine-tuning screw 514, and the fine-tuning handwheel 506 is used to assist manual rotation of the fine-tuning screw 514.

[0091] Reference Figure 7 Specifically, one end of the fine-tuning screw 514 and the side of the fine-tuning locking bracket 504 opposite to the first fixing block 512 are connected to a rotation counter 507. The rotation counter 507 is used to count the number of rotations of the screw so that the operator can accurately evaluate the fine adjustment height of the pressure roller mechanism 4.

[0092] For example, when the rotary counter 507 shows that the fine-tuning screw 514 rotates 0.1 revolutions, the pressure roller mechanism 4 rises or falls by 0.005 mm.

[0093] Reference Figure 5 as well as Figure 7 Specifically, the upper wedge 516 facing the lower wedge 517 or the lower wedge 517 facing the upper wedge 516 is provided with an upper rolling member 518, which is used to reduce the frictional force when the lower wedge 517 rolls relative to the upper wedge 516.

[0094] The lower wedge 517 is provided with a lower rolling element (not shown in the figure) on the side facing the bracket 511 or the bracket 511 is provided with the side facing the lower wedge 517. The lower rolling element is used to reduce the frictional force when the lower wedge 517 rolls relative to the bracket 511, so as to improve the smoothness of the adjustment assembly 51 during adjustment, reduce the adjustment resistance, and improve the stability of the structure of the adjustment assembly 51.

[0095] Specifically, the upper rolling element 518 consists of several rolling columns arranged side by side.

[0096] Reference Figure 5 as well as Figure 7 More specifically, the adjustment assembly 51 also includes a socket 501, a pin 502, and a fixed mounting base 503. The fixed mounting base 503 is fixedly connected to one end of the bracket 511, and the fixed mounting base 503 is detachably connected to the mounting frame 3.

[0097] The insertion socket 501 is provided with an insertion hole 5011, the hole axis of which is parallel to the rotation axis of the roller 2. The pin seat 502 is provided with a pin 5021 that matches the insertion hole 5011. The pin seat 502 or the insertion socket 501 is fixedly connected to the other end of the bracket 511. When the pin seat 502 is fixedly connected to the other end of the bracket 511, the insertion socket 501 is fixedly connected to the mounting frame 3. When the insertion socket 501 is fixedly connected to the other end of the bracket 511, the pin seat 502 is fixedly connected to the mounting frame 3.

[0098] Taking the fixed connection between the pin seat 502 and the other end of the bracket 511 as an example, when the adjustment component 51 needs to be disassembled from the device, first disconnect the connection between the fixed mounting base 503 and the mounting frame 3. Then, along the axial direction of the insertion hole 5011, pull the bracket 511, causing the pin seat 502, the first fixing block 512, the second fixing block 513, the fine-tuning screw 514, the fine-tuning screw nut 515, the lower wedge block 517, and (fine-tuning locking mounting base 504, fine-tuning locking element 505, rotation counter 507, and fine-tuning handwheel 506) to be simultaneously pulled out, facilitating quick disassembly and maintenance of the device. It is understood that the installation process is the reverse of the disassembly process described above.

[0099] Specifically, the second mounting plate 5212 and the third mounting plate 5213 are slidably connected to the mounting frame 3. The mounting frame 3 is provided with a vertical slide rail 31. The second mounting plate 5212 and the third mounting plate 5213 are fixed with vertical sliders 32 that slide on the vertical slide rail 31. When the lifting drive 522 drives the mounting bracket 521 to move up and down, the vertical slider 32 slides on the vertical slide rail 31 to ensure that the lifting drive 522 drives the mounting bracket 521 to slide smoothly and drives the pressure roller mechanism 4 to rise and fall smoothly.

[0100] Reference Figure 5 as well as Figure 8 Specifically, the pressure roller mechanism 4 includes a pressure roller 41, a rotating shaft 42, and a fixed block 43;

[0101] The rotating shaft 42 passes through the rotation center of the pressure roller 41 and is fixedly connected to the pressure roller 41;

[0102] The second mounting plate 5212 and the third mounting plate 5213 are both provided with mounting grooves 44. The fixing block 43 is detachably connected to the mounting bracket 521. The two ends of the rotating shaft 42 are respectively rotatably disposed in the space enclosed by the mounting groove 44 and the fixing block 43.

[0103] It is understandable that when installing the pressure roller mechanism 4, the rotating shaft 42 is first placed into the mounting groove 44, and then the fixing block 43 is installed. The fixing block 43 is fixed with screws and other parts, thereby fixing the pressure roller mechanism 4 on the mounting bracket 521. The disassembly process is the opposite. It can be seen that the pressure roller mechanism 4 in this embodiment has a simple structure and is easy to disassemble and install.

[0104] Reference Figure 1 , Figure 3 as well as Figure 4 In one embodiment, the pressure roller leveling mechanism 6 includes a transition frame 61, a slide rail 62, a slider 63, a leveling screw 64, a leveling screw nut 65, a locking mounting block 66, and a screw locking component 67.

[0105] The slide rail 62 is fixedly mounted on the mounting bracket 1, and the slider 63 is slidably mounted on the slide rail 62;

[0106] The mounting frame 3 is fixedly mounted on the slider 63;

[0109] The locking mounting block 66 is fixedly connected to the transition frame 61 and rotatably connected to the horizontal adjusting screw 64. The screw locking member 67 is provided on the locking mounting block 66 and is used to restrict the rotation of the horizontal adjusting screw 64.

[0110] Rotating the horizontal adjusting screw 64 converts the rotational motion of the horizontal adjusting screw 64 into linear motion, thereby driving the mounting frame 3, the mounting pressure roller mechanism 4, and the pressure roller lifting drive mechanism 5 to slide on the slide rail 62, adjusting the position of the pressure roller mechanism 4 along the axial direction of the roller 2.

[0111] Specifically, the pressure roller leveling mechanism 6 also includes a dust cover 68, which is fixed to the mounting frame 3 to reduce dust accumulation at the slide rail 62 and prevent dust from affecting the movement of the mounting frame 3.

[0112] As an example, the dust cover 68 is a rigid metal cover or a bellows cover.

[0113] Reference Figure 5 In one embodiment, it also includes a base 7 and a dust removal mechanism;

[0114] The base 7 is located below the roller 2, and one side of the base 7 is fixedly connected to the mounting frame 1;

[0115] The base 7 has a chamber 71 inside, which is used to contain the dust generated by the roller pressing of the electrode tabs. The dust removal mechanism is connected to the chamber 71 to remove the dust and improve the cleanliness of the workshop environment.

[0116] Specifically, the dust removal mechanism includes a suction pipe 81, which is connected to an external negative pressure generating device. When the negative pressure generating device is activated, dust can be adsorbed.

[0117] Specifically, the dust removal mechanism also includes an isolation net 82, which is placed at the entrance of the chamber 71 to prevent the tabs and electrodes from being adsorbed into the chamber 71.

[0118] In one embodiment, a roller drive assembly 9 is further included. The fixed end of the roller drive assembly 9 is mounted on the mounting frame 1, and the output end of the roller drive assembly 9 is connected to the roller 2 for transmission. When the electrode tab is rolled, the roller drive assembly 9 drives the roller 2 to rotate, thereby driving the electrode tab to move synchronously and providing power for the movement of the electrode tab and the electrode sheet.

[0119] Specifically, the roller drive assembly 9 includes a drive motor 91, a planetary reducer 92, and a coupling 93. The coupling 93 is connected to one end of the roller 2, and the planetary reducer 92 is rotatably connected to the coupling 93.

[0120] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
