[0034] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0035] In this application, the term "parallel" includes not only absolute parallelism but also approximate parallelism as commonly understood in engineering. For example, "parallel" refers to the angle between two lines, a line and a surface, or a surface, where the angle is between -1° and 1°. Similarly, "perpendicular" also includes not only absolute perpendicularity but also approximate perpendicularity as commonly understood in engineering. For example, "perpendicular" refers to the angle between two lines, a line and a surface, or a surface, where the angle is between 89° and 91°. Equal distances or equal angles include not only absolute equality but also approximate equality as commonly understood in engineering, meaning there may be a certain degree of error, such as a tolerance range of -1% to 1%.

[0036] This application provides an electrode coating apparatus that can be used to manufacture various products, such as lithium batteries. The electrode coating apparatus has a first direction X, a second direction Y, and a third direction Z, all of which intersect each other. It is understood that the angles between the first direction X, the second direction Y, and the third direction Z can be set according to usage requirements; for example, the first direction X, the second direction Y, and the third direction Z may intersect each other.

[0037] Reference Figures 1 to 9 As shown, the electrode coating equipment includes a main body, a printing roller 53, and a doctor blade device. The doctor blade device includes a mounting plate 10, an adjusting mechanism 20, and a doctor blade 50. The main body is connected to both the printing roller 53 and the doctor blade device. At the point where the printing roller 53 contacts the doctor blade 50, the doctor blade 50 scrapes off excess coating liquid from the printing roller 53, leaving only a thin, uniform coating layer to ensure that the coating is evenly applied to the substrate.

[0038] In the scraper device, the mounting plate 10 has a first surface 11 with an opening 12. The mounting plate 10 has a mounting cavity 13, and the opening 12 communicates with the mounting cavity 13. The adjustment mechanism 20 is partially disposed in the mounting cavity 13 and partially extends to the outside of the mounting plate 10 along the first direction X. One end of the scraper 50 passes through the opening 12 and is connected to the adjustment mechanism 20, while the other end is exposed outside the mounting plate 10. The extension direction of the scraper 50 intersects with the first direction X. The adjustment mechanism 20 moves back and forth along the first direction X to adjust the intersection angle between the scraper 50 and the first direction X.

[0039] The mounting plate 10 is equipped with a scraper 50 and an adjusting mechanism 20, enabling their installation and fixation. One end of the scraper 50 passes through the opening 12 of the mounting plate 10 and connects to the adjusting mechanism 20, while the other end of the scraper 50 protrudes outside the mounting plate 10. The portion of the scraper 50 protruding outside the mounting plate 10 can connect with the printing roller 53. A portion of the adjusting mechanism 20 is disposed within the mounting cavity 13 of the mounting plate 10, with a localized extension along the first direction X to the outside of the mounting plate 10. The portion of the adjusting mechanism 20 disposed within the mounting cavity 13 connects to the scraper 50, while the portion of the adjusting mechanism 20 protruding outside the mounting plate 10 is used to move the adjusting mechanism 20.

[0040] The electrode coating equipment of this application embodiment includes a doctor blade device, which includes a mounting plate 10, an adjusting mechanism 20, and a doctor blade 50. The mounting plate 10 is provided with an opening 12 and a mounting cavity 13. Part of the adjusting mechanism 20 is disposed in the mounting cavity 13. One end of the doctor blade 50 passes through the opening 12 and is connected to the adjusting mechanism 20. The extension direction of the doctor blade 50 intersects with a first direction X. The adjusting mechanism 20 reciprocates along the first direction X to adjust the intersection angle between the doctor blade 50 and the first direction X. In the electrode coating equipment, the angle of the doctor blade 50 can be adjusted by only adjusting the adjusting mechanism 20, which has the advantages of simplicity and convenience.

[0041] In some embodiments, the cavity wall of the mounting cavity 13 is provided with a first limiting part 15, which extends from the cavity wall of the mounting cavity 13 into the mounting cavity 13. The adjusting rod 21 contacts the plurality of first limiting parts 15 respectively to restrict the movement path of the adjusting rod 21 and ensure that the adjusting rod 21 moves accurately along the first direction X.

[0042] In some embodiments, refer to Figure 1 and Figure 2 As shown, the adjustment mechanism 20 includes an adjustment rod 21. One end of the adjustment rod 21 is disposed in the mounting cavity 13, and the other end extends along the first direction X to the outside of the mounting plate 10. A first groove 22 is provided on the side of the adjustment rod 21 facing the opening 12, and the groove opening of the first groove 22 faces the opening 12. One end of the scraper 50 is disposed in the first groove 22. The adjustment rod 21 reciprocates along the first direction X to push the scraper 50 to rotate through the first groove 22, thereby adjusting the intersection angle between the scraper 50 and the first direction X.

[0043] Reference Figure 1 and Figure 2 As shown, the portion of the adjusting rod 21 located within the mounting cavity 13 has a first groove 22. The opening of the first groove 22 faces the opening 12. One end of the scraper 50 passes through the opening 12 and is inserted into the first groove 22, thus connecting the scraper 50 to the adjusting mechanism 20. This connection between the scraper 50 and the adjusting mechanism 20 is simple and convenient. When the adjusting rod 21 reciprocates along the first direction X, the groove wall of the first groove 22 contacts the inner end of the scraper 50. The first groove 22 pushes the scraper 50 to rotate, adjusting the angle of intersection between the scraper 50 and the first direction X. This angle adjustment of the scraper 50 is simple and convenient.

[0044] In some embodiments, refer to Figure 1 As shown, the adjustment mechanism 20 also includes a first grip portion 25, which is connected to the end of the adjustment rod 21 that extends along the first direction X to the outside of the mounting plate 10. The first grip portion 25 is convenient for the operator to grip, so as to pull the adjustment rod 21 back and forth along the first direction X.

[0045] In some other embodiments, the adjustment mechanism 20 also includes a linear motor connected to the adjustment rod 21. For example, the linear motor is connected to the end of the adjustment rod 21 that extends along the first direction X to the outside of the mounting plate 10. The linear motor drives the adjustment rod 21 to move back and forth along the first direction X, which has the advantage of a high degree of automation.

[0046] In some embodiments, the electrode coating equipment further includes a locking mechanism 30, a portion of which is disposed within the mounting cavity 13. The locking mechanism 30 is connected to the adjusting mechanism 20 to lock the adjusting rod 21. In the above structure of this application embodiment, the locking mechanism 30 can lock the adjusting rod 21 to prevent the angle of the scraper 50 from changing during use and affecting the normal production of the electrode coating equipment.

[0047] In some embodiments, refer to Figure 1 , Figure 5 and Figure 6 As shown, the adjusting rod 21 is provided with a plurality of limiting holes 23 on the side opposite to the opening 12, and the plurality of limiting holes 23 are spaced apart along the first direction X; the locking mechanism 30 includes a locking rod 31, one end of the locking rod 31 is provided in the mounting cavity 13 and is adapted to be inserted into any of the limiting holes 23 to lock the adjusting rod 21, and the other end of the locking rod 31 extends to the outside of the mounting plate 10 along the second direction Y.

[0048] In this embodiment, the portion of the adjusting rod 21 located within the mounting cavity 13 is provided with multiple limiting holes 23, and these multiple limiting holes 23 are located on the side of the adjusting rod 21 facing away from the opening 12. Further refer to... Figure 6 As shown, the limiting hole 23 is a blind hole.

[0049] In the scraper device of this application embodiment, multiple limiting holes 23 are spaced apart along the first direction X. When one end of the locking rod 31 is inserted into different limiting holes 23, the intersection angle between the scraper 50 and the first direction X is different. By inserting one end of the locking rod 31 into the corresponding limiting hole 23, the intersection angle between the scraper 50 and the first direction X can be made to meet the usage requirements. The angle adjustment and angle locking of the scraper 50 have the advantages of being simple and convenient.

[0050] In some embodiments, refer to Figure 1 As shown, the locking mechanism 30 also includes a second gripping part 33. One end of the locking rod 31 is disposed in the mounting cavity 13 and is adapted to be inserted into any of the limiting holes 23. The other end of the locking rod 31 is disposed outside the mounting plate 10 and connected to the second gripping part 33. The second gripping part 33 facilitates the operation of the limiting rod 32 by the operator.

[0051] In some embodiments, refer to Figures 1 to 6As shown, a limiting groove 24 is provided on the side of the adjusting rod 21 away from the opening 12. The limiting groove 24 is recessed from the surface of the adjusting rod 21 away from the opening 12 toward the opening 12. The locking mechanism 30 also includes a limiting rod 32. One end of the limiting rod 32 is provided in the mounting cavity 13 and is adapted to be inserted into the limiting groove 24. The other end of the limiting rod 32 is provided outside the mounting plate 10. The limiting rod 32 is used to limit the movement range of the adjusting rod 21 in the first direction X when the locking rod 31 is not inserted into any of the limiting holes 23.

[0052] In this embodiment, the portion of the adjusting rod 21 located within the mounting cavity 13 is provided with a limiting groove 24, and the limiting groove 24 is located on the side of the adjusting rod 21 facing away from the opening 12, as shown in the reference. Figure 1 As shown, the limiting groove 24 is recessed from the adjustment rod 21 away from the surface of the opening 12 and towards the opening 12.

[0053] In the scraper device of this application embodiment, when the locking rod 31 is not inserted into any of the limiting holes 23, one end of the limiting rod 32 is inserted into the limiting groove 24. The limiting rod 32 can limit the movement range of the adjusting rod 21 in the first direction X, and prevent the movement range of the adjusting rod 21 in the first direction X from being too large, which would cause the locking rod 31 to be unable to be inserted into any of the limiting holes 23, and the adjusting rod 21 to be completely dislodged from the mounting cavity 13.

[0054] In some embodiments, refer to Figure 1 and Figure 3 As shown, the locking mechanism 30 also includes a limiting rod 32, one end of which is disposed in the mounting cavity 13 and adapted to be inserted into the limiting groove 24, and the other end of which is disposed outside the mounting plate 10 and connected to the third gripping part 34. The third gripping part 34 facilitates the operation of the limiting rod 32 by the operator.

[0055] In some embodiments, refer to Figure 1 and Figure 3 As shown, the limiting hole 23 is disposed at the bottom of the limiting groove 24, and the limiting hole 23 is recessed from the bottom of the limiting groove 24 toward the opening 12; the limiting rod 32 is provided with a through hole extending along the second direction Y in the middle; one end of the locking rod 31 passes through the through hole to be inserted into any of the limiting holes 23. The above-described structure of the embodiments of this application makes the scraper device have the advantage of compact structure.

[0056] It is understandable that the connection method between the limiting rod 32 and the mounting plate 10 is set according to the usage requirements. For example, the mounting plate 10 is provided with a mounting plate threaded hole, which connects the mounting cavity 13 and the outside of the mounting plate 10. The side wall of the limiting rod 32 is provided with an external thread, and the limiting rod 32 passes through the mounting plate threaded hole and is threaded with the mounting plate threaded hole.

[0057] To enhance the stability and connection strength of the limit rod 32 after it is connected to the mounting plate 10, refer to Figure 3 As shown, the mounting plate 10 is also provided with a second limiting part 16, which protrudes into the mounting cavity 13 and forms part of the mounting plate threaded hole. The provision of the second limiting part 16 increases the length of the mounting plate threaded hole in the second direction Y, thereby increasing the connection area between the limiting rod 32 and the mounting plate 10, making the connection between the limiting rod 32 and the mounting plate 10 more stable and stronger.

[0058] In some embodiments, the through hole extending along the second direction Y in the middle of the limiting rod 32 is a threaded hole for the limiting rod, and the side wall of the locking rod 31 is provided with external threads. The locking rod 31 passes through the threaded hole of the limiting rod and is threaded with the threaded hole of the limiting rod. The above structure of the embodiments of this application has the advantage of simple and convenient connection between the limiting rod 32 and the locking rod 31.

[0059] In some embodiments, the electrode coating apparatus further includes a connecting mechanism, which is connected to the doctor blade 50 and the mounting plate 10 respectively, so as to movably connect the doctor blade 50 and the mounting plate 10.

[0060] In the above structure of this application embodiment, the scraper 50 and the mounting plate 10 are connected by a connecting mechanism to movably connect the scraper 50 and the mounting plate 10. This has the advantages of simple and convenient connection, and allows the scraper 50 to adjust its angle.

[0061] In some embodiments, the connecting mechanism includes a hinge 41, which includes a first blade 42 and a second blade 43; the first blade 42 is disposed in the opening 12 and is connected to the side wall of the opening 12, and the second blade 43 is connected to the scraper 50.

[0062] Understandably, referring to Figure 2 As shown, hinge 41 also includes a pin 44, which is rotatably connected to the first blade 42 and the second blade 43, respectively, so that the first blade 42 and the second blade 43 can rotate relative to each other. Therefore, when the first blade 42 is connected to the side wall of the opening 12 and the second blade 43 is connected to the scraper 50, the scraper 50 can rotate relative to the mounting plate 10 to achieve a movable connection between the scraper 50 and the mounting plate 10.

[0063] In some embodiments, refer to Figure 2 As shown, the connecting mechanism also includes a fastener 57. The second blade 43 is provided with a threaded hole, and the fastener 57 is connected to the threaded hole. The end of the fastener 57 passing through the threaded hole abuts against the scraper 50. In the above structure of this embodiment, the end of the fastener 57 passing through the threaded hole abuts against the scraper 50, which can limit the relative position of the second blade 43 and the scraper 50, so that the second blade 43 and the scraper 50 are connected, which has the advantages of simple and convenient connection.

[0064] In some embodiments, to prevent the coating material from corroding the scraper 50, mounting plate 10, etc., a seal is provided between the sidewall of the first blade 42 and the opening 12, and at the connection position between the second blade 43 and the scraper 50.

[0065] In some embodiments, refer to Figure 4 As shown, the opening 12 is a strip-shaped opening extending along a third direction Z. At least two openings 12 are provided, and the at least two openings 12 are spaced apart along a first direction X. Each opening 12 is provided with at least one scraper 50. The above structure of the embodiment of this application can realize the setting of multiple scrapers 50 to meet the usage requirements of the electrode coating equipment for the number of scrapers.

[0066] It is understandable that the number of openings 12 and the number of scrapers 50 in each opening 12 are set according to the usage requirements. For example, in a specific embodiment, two openings 12 are set, and one scraper 50 is set in each opening. In this case, the scraper device in the electrode coating equipment is a double scraper device.

[0067] Currently, when using a single-blade device in electrode coating equipment, it is difficult to achieve uniform coating of extremely thin coatings over a long period, easily leading to problems such as tab scratches, edge stringing, and blade wear. Therefore, frequent blade replacement is necessary. Frequent blade replacement obviously affects the production efficiency of the electrode coating equipment and increases its operating costs. While using a harder blade can reduce blade wear, the close contact between the blade and the printing roller 53 (e.g., in lithium battery gravure coating machines) means that excessively hard blade material easily wears down the printing roller 53. Since the mesh or grooves on the printing roller 53 require high precision and are costly, excessively hard blades further increase the operating costs of the electrode coating equipment. In this embodiment, with a dual-blade device, continuous production of the electrode coating equipment can be achieved over a long period, solving the problem of frequent blade replacement, greatly improving production efficiency, coating quality, and reducing costs.

[0068] In some embodiments, to prevent dust particles in the environment from easily adhering to the surface of the rollers, causing scratches on the rollers 53 and electrode surfaces by the doctor blade 50 during electrode coating equipment operation, the electrode coating equipment also includes a protective cover 51, which covers the area where the doctor blade device is located. The protective cover 51 also serves to ensure the safety of operators. An observation window 52 is provided on the protective cover 51 to facilitate operators' observation of the doctor blade device and related positions, allowing for real-time monitoring of the coating process.

[0069] In some embodiments, the scraper device is made of high-strength stainless steel, which has sufficient rigidity and corrosion resistance, and has a long service life in high-humidity workshops.

[0070] In some embodiments, the electrode coating equipment includes a scraper device, a locking mechanism 30, and a connecting mechanism. The scraper device includes a mounting plate 10, an adjusting mechanism 20, and a scraper 50. The locking mechanism 30 includes a locking rod 31, a limiting rod 32, a second gripping part 33, and a third gripping part 34. The connecting mechanism includes a first blade 42, a second blade 43, and a pin 44.

[0071] Reference Figures 1 to 6 As shown, when the angle of the scraper 50 needs to be adjusted, the locking rod 31 is turned so that one end of the locking rod 31 moves out of the limiting hole 23. Then, the adjusting rod 21 is pulled along the first direction X by the first gripping part 25. During the movement of the adjusting rod 21, the intersection angle between the scraper 50 and the first direction X is adjusted to the required value. Then, the locking rod 31 is turned again so that one end of the locking rod 31 is inserted back into the limiting hole 23 to lock the adjusting rod 21. In this way, the adjustment of the scraper 50 can be completed. In the electrode coating equipment of this application embodiment, the angle of the scraper 50 can be finely adjusted by the adjusting mechanism 20 alone. The fine adjustment angle is, for example, ±5°. The angle adjustment of the scraper 50 has the advantages of being simple and convenient.

[0072] Reference Figure 6 As shown, the electrode coating equipment also includes a rubber roller 54, a foil 55, a printing roller 53, and a material trough 56. The lower end of the printing roller 53 is positioned within the material trough 56, and the foil 55 is positioned between the upper end of the printing roller 53 and the rubber roller 54. The end of the doctor blade 50 facing away from the mounting plate 10 contacts the outer periphery of the printing roller 53, removing excess coating material from the printing roller 53. Furthermore, as production progresses, the angle of the doctor blade 50 is adjusted in real time via the adjusting mechanism 20 to adapt to different coating conditions, such as the required angle of the doctor blade 50 and the pressure requirements between it and the printing roller.
