Description

Technical Field

[0001] This utility model relates to the field of lithium battery manufacturing technology, and in particular to a pressure roller structure for a lithium battery coating machine. Background Technology

[0002] With the widespread application of lithium batteries in society, lithium-ion batteries are not only widely used in consumer electronics products, but also have great potential in the power battery market for electric vehicles and industrial energy storage. In the production process of lithium batteries, the coating process is a crucial link, so a pressure roller structure for lithium battery coating machines is needed.

[0003] Traditional pressure rollers are difficult to maintain surface flatness over long periods, and wear easily occurs after prolonged use, resulting in uneven roller surfaces. This affects the coating quality of the electrode sheets, leading to uneven electrode thickness and consequently impacting the performance consistency of lithium batteries. Existing technologies improve the pressure rollers by using high-hardness materials, which enhance their lifespan and prevent deformation, thus achieving uniform electrode thickness after coating. However, in actual use, the pressure rollers cannot automatically adjust according to the material thickness and cannot effectively buffer pressure fluctuations during coating, resulting in uneven pressure on the electrode sheets. This further reduces the uniformity of electrode thickness after coating and diminishes the practicality of the device. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a pressure roller structure for a lithium battery coating machine, aiming to improve the problem that the existing technology cannot effectively buffer pressure fluctuations during the coating process, resulting in uneven pressure of the pressure roller on the electrode sheet, thereby reducing the thickness consistency of the electrode sheet after coating and reducing the practicality of the device.

The plates are slidably connected. The inner wall of the hollow sleeve on the left is threaded with a threaded rod one, and the inner wall of the hollow sleeve on the right is threaded with a threaded rod two. The bottom end of the threaded rod two is rotatably connected to the base plate. Both the outer walls of the threaded rod one and the threaded rod two are fixedly connected with ratchet wheels. The outer wall of the ratchet wheel on the left is provided with a chain. The two ratchet wheels are connected to each other through the chain drive. The top left side of the base plate is fixedly connected with a motor. The output end of the motor is fixedly connected to the threaded rod one. A cleaning mechanism is provided on the rear side of the outer wall of the pressure roller. The cleaning mechanism is used to clean the residue on the surface of the pressure roller.

[0006] As a further description of the above technical solution:

[0007] The cleaning mechanism includes two fixed rings, which are rotatably connected to the left and right sides of the outer wall of the pressure roller, respectively. A collection frame is fixedly connected to the rear side of the outer wall of the two fixed rings. A scraper is fixedly connected to the top front side of the collection frame. Slide rods are fixedly connected to the left and right sides of the outer wall of the collection frame. Limit grooves are formed on the outer walls of the two upright plates. The two slide rods are slidably connected to the corresponding limit grooves. A rotating plate is rotatably connected to the bottom of the collection frame. Hooks are fixedly connected to the left and right sides of the rear end of the outer wall of the collection frame. Buckles are fixedly connected to the left and right sides of the rear end of the outer wall of the rotating plate. The two buckles are engaged with the corresponding hooks.

[0008] As a further description of the above technical solution:

[0009] An installation box is fixedly connected to the top of the left-side upright plate, and an alarm light is fixedly connected to the inner wall of the installation box.

[0010] As a further description of the above technical solution:

[0011] Pressure sensors are fixedly connected to the top of the two opposite sides of the two upright plates, and the bottom ends of the two pressure sensors are fixedly connected to the corresponding mounting bases.

[0012] As a further description of the above technical solution:

[0013] A mounting plate is fixedly connected to the front side of the outer wall of the left-side upright plate, and a controller is fixedly connected to the left side of the outer wall of the mounting plate.

[0014] As a further description of the above technical solution:

[0015] Each of the two upright plates has a groove on the bottom of an adjacent side, and a collection box is slidably connected between the adjacent grooves.

[0016] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the first threaded rod is driven by a motor, which in turn drives the second threaded rod via a ratchet and chain transmission, causing the hollow sleeves on both sides to move synchronously. With the help of the slider guide, the pressure roller moves smoothly up and down. At the same time, the spring assembly plays an elastic buffering role, effectively solving the problem of not being able to effectively buffer pressure fluctuations, ensuring that the pressure roller applies uniform pressure to the electrode sheet, improving the consistency of the electrode sheet thickness after coating, greatly enhancing the practicality of the device, meeting the precise pressure requirements of different coating processes, and ensuring the coating quality of lithium battery electrode sheets.

[0022] 2. In this utility model, when the pressure roller rotates, the fixed ring remains relatively stationary due to the limitation of the positioning groove, allowing the scraper to stably contact the surface of the pressure roller, efficiently scraping off impurities and collecting them into the collection frame. This effectively prevents impurity residue from affecting the coating quality. At the same time, the cooperation between the slide bar and the positioning groove ensures that the collection frame can follow synchronously when the pressure roller moves up and down, ensuring that the cleaning work is not affected by the change in the position of the pressure roller. When cleaning impurities, simply open the latch and hook engagement, and rotate the rotating plate to easily pour out the impurities. The operation is simple and quick, effectively maintaining the cleanliness of the pressure roller and laying a solid foundation for ensuring the coating quality of lithium battery electrodes.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of a pressure roller structure for a lithium battery coating machine, including a base plate 1. The base plate 1 serves as the basic support for the entire device, providing an installation platform for other components. Vertical plates 3 are fixedly connected to the top left and right sides of the base plate 1, providing vertical support and positioning. A rotating roller 4 is rotatably connected between adjacent vertical plates 3, driving the lithium battery electrode sheets to move on their surface. Mounting seats 6 are slidably connected to the opposite sides of the two vertical plates 3, allowing the mounting seats 6 to slide on the vertical plates 3, thereby adjusting the position of the pressure roller 5. A pressure roller 5 is rotatably connected between adjacent mounting seats 6, cooperating with the rotating roller 4 to apply pressure to the lithium battery electrode sheets passing between them. The bottom of the two mounting seats 6... Each part is fixedly connected to a spring assembly 7, which has an elastic buffering function and can automatically adjust the pressure according to the thickness change of the electrode sheet when the pressure roller 5 is working. Hollow sleeves 8 are fixedly connected to the bottom of each of the two spring assemblies 7. Slider 9 is fixedly connected to an adjacent side of each of the two hollow sleeves 8. The slider 9 is slidably connected to the vertical plate 3. When the hollow sleeves 8 move up and down, the slider 9 slides along the vertical plate 3, serving as a guide. A threaded rod 11 is threadedly connected to the inner wall of the left hollow sleeve 8, and a threaded rod 2 12 is threadedly connected to the inner wall of the right hollow sleeve 8. The bottom end of the threaded rod 2 12 is rotatably connected to the base plate 1, providing a rotational support point for the threaded rod 2 12. Ratchets 13 are fixedly connected to the middle of the outer walls of both the threaded rod 11 and the threaded rod 2 12. The ratchet 13 cooperates with the chain 14 to achieve synchronous rotation of the threaded rod 11 and the threaded rod 12, allowing the two ends of the pressure roller 5 to be adjusted in height simultaneously and equally. A chain 14 is installed on the outer wall of the left ratchet 13, transmitting power between the two ratchet 13s. Both ratchet 13s are connected via the chain 14, thus achieving synchronous rotation of the threaded rod 11 and the threaded rod 12. A motor 15 is fixedly connected to the top left of the base plate 1, providing rotational power to the threaded rod 11. The output end of the motor 15 is fixedly connected to the threaded rod 11, transmitting its power to the threaded rod 11, enabling it to rotate according to the control of the motor 15, thereby driving the pressure roller 5 to adjust in height. For pressure adjustment, a cleaning mechanism 2 is provided on the rear side of the outer wall of the pressure roller 5. The cleaning mechanism 2 is specifically used to clean the residue on the surface of the pressure roller 5. A mounting box 10 is fixedly connected to the top of the left vertical plate 3. The mounting box 10 provides an installation position for the alarm light 16. The alarm light 16 is fixedly connected to the inner wall of the mounting box 10. The alarm light 16 is used to issue a warning in case of abnormality, reminding the operator to make timely adjustments. Pressure sensors 17 are fixedly connected to the top of the two vertical plates 3 on the opposite sides. The pressure sensors 17 monitor the pressure on the pressure roller 5 in real time. The bottom ends of the two pressure sensors 17 are fixedly connected to the corresponding mounting seats 6 to ensure that the pressure sensors 17 can accurately detect the pressure on the pressure roller 5 and provide accurate data support for pressure adjustment.

[0032] Specifically, firstly, motor 15 is started. Motor 15 outputs power to drive the threaded rod 11 to rotate. Since the threaded rod 11 is threadedly connected to the inner wall of the left hollow sleeve 8, the left hollow sleeve 8 will move up and down along the axial direction of the threaded rod 11. Because the two ratchet wheels 13 are connected by a chain 14, when the left ratchet wheel 13 rotates with the threaded rod 11, the right ratchet wheel 13 rotates synchronously, thereby driving the threaded rod 12 to rotate. The right hollow sleeve 8 also moves up and down along the axial direction of the threaded rod 12. When the hollow sleeve 8 moves, the slider 9 connected to it slides on the vertical plate 3, playing a guiding role and ensuring smooth movement. The downward movement drives the mounting base 6 and pressure roller 5 to move up and down via the spring assembly 7, thereby adjusting the distance and pressure between the pressure roller 5 and the rotating roller 4. When coating lithium battery electrodes is required, the electrodes pass between the rotating roller 4 and the pressure roller 5. Under the elastic action of the spring assembly 7 and the height adjustment driven by the motor 15, the pressure roller 5 applies appropriate and uniform pressure to the electrodes to meet the pressure requirements of different coating processes and ensure coating quality. The alarm light 16 in the mounting box 10 at the top of the left vertical plate 3 is used for abnormal warning. The pressure sensors 17 on the top of the outer sides of the two vertical plates 3 are connected to the mounting base 6 at the bottom to monitor the pressure of the pressure roller 5 in real time.

[0033] Reference Figure 1 , Figure 4 and Figure 5 The cleaning mechanism 2 includes two fixed rings 201, which are rotatably connected to the left and right sides of the outer wall of the pressure roller 5, respectively, providing a basis for the synchronous movement of the cleaning mechanism 2 and the pressure roller 5 and the connection of subsequent components. A collection frame 202 is fixedly connected to the rear side of the outer wall of the two fixed rings 201 to collect the residue cleaned from the surface of the pressure roller 5. A scraper 203 is fixedly connected to the top front side of the collection frame 202. The scraper 203 scrapes off the surface residue when the pressure roller 5 rotates, causing it to fall into the collection frame 202. Slide rods 204 are fixedly connected to the left and right sides of the outer wall of the collection frame 202. Limit grooves 208 are provided on the outer walls of the two vertical plates 3, and the two slide rods 204 are respectively connected to the corresponding limit grooves. The corresponding limiting groove 208 is slidably connected, and the slide rod 204 is slidably connected to the limiting groove 208, which restricts the movement trajectory of the collection frame 202 and provides support to ensure its smooth movement. The bottom of the collection frame 202 is rotatably connected to the rotating plate 205. The left and right sides of the rear end of the outer wall of the collection frame 202 are fixedly connected to the hooks 206. The left and right sides of the rear end of the outer wall of the rotating plate 205 are fixedly connected to the latches 207. The two latches 207 are respectively engaged with the corresponding hooks 206. When cleaning the residue, the latches are opened and the rotating plate 205 is rotated to pour out the residue in the collection frame 202. The operation is convenient and ensures that the cleaning mechanism 2 works continuously and effectively.

[0034] Specifically, when the pressure roller 5 rotates, the fixed ring 201 connected to the left and right sides of its outer wall is restricted to a stationary position by the limiting groove 208. The scraper 203 on the front side of the top of the collection frame 202 contacts the surface of the pressure roller 5, scraping off the impurities on the surface of the pressure roller 5 and letting them fall into the collection frame 202. At the same time, the sliding rods 204 on the left and right sides of the collection frame 202 can slide up and down in the limiting groove 208 on the outer wall of the vertical plate 3, ensuring that the collection frame 202 can move up and down synchronously with the pressure roller 5 when it moves up and down. When it is necessary to clean the impurities, the latches 207 on the left and right sides of the rear end of the rotating plate 205 and the latches 206 on the left and right sides of the rear end of the collection frame 202 are engaged. Rotating the rotating plate 205 will pour out the impurities. The operation is convenient, effectively maintaining the cleanliness of the pressure roller and ensuring the coating quality.

[0035] Reference Figure 1 , Figure 2 and Figure 3 A mounting plate 18 is fixedly connected to the front of the outer wall of the left vertical plate 3, providing an installation position for the controller 19. The controller 19 is fixedly connected to the left side of the outer wall of the mounting plate 18, serving as the control core of the entire device. It is used to receive signals from components such as the pressure sensor 17 and to precisely control the actuators such as the motor 15 according to a preset program. Slide grooves 20 are provided on the bottom of adjacent sides of the two vertical plates 3, providing a track for the sliding of the collection box 21. The collection box 21 is slidably connected between the adjacent slide grooves 20, which is used to collect impurities that may be spilled when cleaning residue from the collection frame 202, preventing impurities from contaminating the working area, and facilitating centralized treatment of impurities to maintain a clean working environment.

[0036] Specifically, the controller 19 is fixed on the front mounting plate 18 of the left upright plate 3. It receives data from the control device to meet the coating process requirements. The collection box 21 slides in the bottom groove 20 on the adjacent sides of the two upright plates 3 to collect impurities spilled during the secondary cleaning of the collection frame 202 and maintain the cleanliness of the work area.

[0037] Reference Figure 1 , Figure 3 and Figure 5 An information board 22 is provided on the front side of the outer wall of the collection box 21 to record information related to the collection box 21. Screws 23 are threaded at the four corners of the front side of the outer wall of the information board 22. The rear ends of two screws 23 are threaded to the collection box 21 to ensure that the information board 22 will not fall off during equipment operation. Bolts 24 are threaded around the top of the outer wall of the base plate 1. The bolts 24 are used to fix the entire lithium battery coating machine pressure roller structure to other equipment or platforms. The surfaces of multiple bolts 24 are smoothed to prevent dust and other impurities from adhering to the surface of the bolts 24.

[0038] Specifically, an information board 22 is set on the front of the collection box 21. The four corners of the information board 22 are threaded to the collection box 21 by screws 23, which are used to record relevant information of the collection box 21. The top of the base plate 1 is threaded with bolts 24 around the perimeter. The surface of the bolts 24 is smooth. On the one hand, it is easy to fix the device to other equipment or platforms by bolts 24. On the other hand, it can prevent the rough surface of the bolts 24 from scratching the operators or surrounding objects. It also reduces the adhesion of dust and other impurities, which helps to keep the equipment clean.

[0039] Working principle: First, start motor 15. Motor 15 outputs power to drive threaded rod 11 to rotate. Based on the threaded connection between threaded rod 11 and the inner wall of the left hollow sleeve 8, the left hollow sleeve 8 will move up and down along the axial direction of threaded rod 11. At the same time, since the two ratchet wheels 13 are connected by chain 14, when the left ratchet wheel 13 rotates with threaded rod 11, the right ratchet wheel 13 will also rotate synchronously, thereby driving threaded rod 12 to rotate, so that the right hollow sleeve 8 also moves up and down along the axial direction of threaded rod 12. During the movement of hollow sleeve 8, the slider 9 connected to it moves on the vertical plate 3. The upward sliding mechanism serves as a guide, ensuring the smooth movement of the hollow sleeve 8. As the hollow sleeve 8 moves up and down, the spring assembly 7 drives the mounting base 6 and the pressure roller 5 to move up and down synchronously, thereby adjusting the distance and pressure between the pressure roller 5 and the rotating roller 4. When the lithium battery electrode coating operation is performed, the electrode passes between the rotating roller 4 and the pressure roller 5. At this time, the pressure roller 5, with the help of the elastic buffer of the spring assembly 7 and the height adjustment achieved by the motor 15, can apply appropriate and uniform pressure to the electrode, thereby meeting the precise pressure requirements of various coating processes and effectively ensuring the coating quality of the lithium battery electrode.

[0040] Furthermore, when the pressure roller 5 rotates, the fixed ring 201 connected to the left and right sides of its outer wall is restricted to a stationary position by the limiting groove 208. The scraper 203 on the front side of the top of the collection frame 202 contacts the surface of the pressure roller 5, scraping off the impurities on the surface of the pressure roller 5 and letting them fall into the collection frame 202. At the same time, the sliding rods 204 on the left and right sides of the collection frame 202 can slide up and down in the limiting groove 208 on the outer wall of the vertical plate 3, ensuring that the collection frame 202 can move up and down synchronously with the pressure roller 5 when it moves up and down. When it is necessary to clean the impurities, the latches 207 on the left and right sides of the rear end of the rotating plate 205 and the latches 206 on the left and right sides of the rear end of the collection frame 202 are engaged. Rotating the rotating plate 205 will pour out the impurities. The operation is convenient, effectively maintaining the cleanliness of the pressure roller and ensuring the coating quality.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
