Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, specifically to an air flotation nozzle structure and a climbing mechanism. Background Technology

[0002] During the lithium battery coating and drying process, after the electrode sheet is coated and dried on one side, it is taken out of the oven for double-sided coating. After double-sided coating, it is climbed by the climbing mechanism to the second-layer oven for drying. After drying, it is rolled up.

[0003] After single-sided coating, the electrode sheet contacts the solid roller during its ascent via the inclining mechanism, forming a certain wrap angle at the contact area between the roller surface and the electrode sheet. After single-sided coating, the electrode sheet has a tab-free area (copper or aluminum foil without coating) in the middle or on both sides. Theoretically, the coating should be completely adhered to the roller surface, but the tab-free area cannot. During the ascent process, due to the good extensibility of the current collector (copper or aluminum foil), the tab-free area undergoes localized deformation under tension, causing it to contact the roller surface. This creates a triangular gap between the tab-free area and the electrode coating, resulting in indentations and wrinkles in the tab-free area, causing irreversible damage. This can lead to poor welding in subsequent processes, increased battery internal resistance, and even perforation, posing a short-circuit risk. Utility Model Content

Detailed Implementation

[0024] 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.

[0025] Reference Figures 2 to 5 An example of this utility model provides an air flotation nozzle structure, including a support component 1 and an air blowing component 2. The support component 1 is used to support the air blowing component, and the air blowing component 2 is used to blow high-pressure airflow to the tab area of ​​the electrode sheet.

[0026] Specifically, the support assembly 1 includes an optical axis 100 and two support seats 200. The two ends of the optical axis 100 are respectively connected to the two support seats 200. The air blowing assembly 2 includes one or more air boxes 300. A mounting seat 400 is provided on one side of the air box 300. The mounting seat 400 is connected to the optical axis 100. An air inlet pipe 310 and an air outlet 321 are provided on the air box 300. The air outlet 321 corresponds to the blank area of ​​the electrode tab of the electrode plate. The air inlet pipe 310 is connected to an external fan or vacuum pump. The air outlet 321 is used to blow out high-pressure airflow.

[0027] Understandably, the number of air boxes 300 can be flexibly arranged according to the actual production needs and the number of blank areas on the electrode tabs. An external fan or vacuum pump is connected to the air inlet pipe 310 to supply air to the air boxes 300. The airflow forms a high-pressure airflow at the air outlet 321 of the air box 300. The high-pressure airflow provides stable air flotation support for the blank areas on the electrode tabs, thereby avoiding contact between the blank areas on the electrode tabs and the roller surface, and preventing the formation of belt travel marks and wrinkles in the blank areas on the electrode tabs.

[0028] In some preferred embodiments, the support base 200 includes a mounting plate 210, a linear slide 220 disposed on the mounting plate 210, and a fixed base 230 disposed on the linear slide 220. One end of the optical axis 100 is connected to the fixed base 230, and the linear slide 220 is used to adjust the position of the fixed base 230 in the vertical direction.

[0029] It is understandable that the position of the fixed base 230 in the vertical direction can be adjusted by the linear slide 220, thereby realizing the vertical adjustment of the optical axis 100 and the bellows 300 set on the optical axis 100. This facilitates the adjustment of the relative height between the air outlet 321 and the blank area of ​​the electrode tab, ensuring that the high-pressure airflow can accurately act on the target area and improve the air flotation support effect.

[0030] Furthermore, the fixed base 230 is provided with a waist-shaped hole 240, which accommodates one end of the optical axis 100. The length direction of the waist-shaped hole 240 is perpendicular to the adjustment direction of the linear slide 220 and the length direction of the optical axis 100. Both sides of the length direction of the waist-shaped hole 240 are provided with first threaded holes 241, and the first threaded holes 241 are threadedly connected to adjusting bolts 242. One end of the adjusting bolts 242 abuts against the outer periphery of the optical axis 100, and the two adjusting bolts 242 limit the radial sides of the optical axis 100 respectively.

[0031] Understandably, by adjusting the screw depth of the two adjusting bolts 242, it is possible to fine-tune the horizontal position of the optical axis 100. Furthermore, combined with the height adjustment of the linear slide 220, the optical axis 100 can be adjusted in various circumferential positions. This facilitates the adjustment of the distance between the air outlet 321 and the tab clearance area, and facilitates the control of the airflow pressure acting on the tab clearance area, ensuring stable air flotation support.

[0032] Furthermore, limiting planes 110 are provided on both radial sides of the optical axis 100. One end of each of the two adjusting bolts 242 abuts against the two limiting planes 110. The limiting planes 110 provide a precise force application reference surface for one end of the adjusting bolts 242. Compared with the cylindrical surface, the contact area between the adjusting bolts 242 and the limiting planes 110 is increased, thereby forming a more stable mechanical locking force and effectively preventing the optical axis 100 from rotating or shifting under the reaction force of high-pressure airflow or vibration.

[0033] In some preferred embodiments, the mounting base 400 is provided with a through hole 410 through which the optical axis 100 passes. A second threaded hole 420 is provided on one side of the mounting base 400. A set screw is threaded into the second threaded hole 420. Rotating the set screw causes one end of the set screw to abut against or separate from the optical axis 100.

[0034] Understandably, when it is necessary to adjust the position of the bellows 300 along the length of the optical axis 100, loosen the set screw to separate one end of the set screw from the optical axis 100, allowing the bellows 300 to slide along the optical axis 100 to a suitable position, and then tighten the set screw to make one end of the set screw abut against the optical axis 100, thus fixing the bellows 300 on the optical axis 100.

[0035] Furthermore, at least two limiting members 430 are provided on the optical axis 100. The two limiting members 430 are used to limit the two sides of the mounting base 400 respectively. Specifically, the limiting member 430 includes an open bushing 431 and a fastening bolt 432 threadedly connected to the open bushing 431. The open bushing 431 is sleeved on the optical axis 100, and the fastening bolt 432 is used to adjust the tightness of the open bushing 431.

[0036] Understandably, the open bushing 431 is fitted onto the optical shaft 100, and different diameter optical shafts 100 can be adapted by adjusting the tightness of the fastening bolt 432, reducing the precision requirements of the parts and reducing production costs. Moreover, by tightening the fastening bolt 432, the position of the open bushing 431 can be quickly fixed, thereby achieving rigid positioning on both sides of the mounting base 400, preventing the bellows 300 from shifting along the length of the optical shaft 100 due to vibration or airflow reaction force, ensuring that the air outlet 321 is always aligned with the blank area of ​​the tab, and further ensuring the firmness of the bellows 300 on the optical shaft 100.

[0037] Reference Figure 5 In some preferred embodiments, the bellows 300 has a square structure, with one side of the bellows 300 protruding outward to form a nozzle 320. An air outlet 321 is disposed on the nozzle 320. The nozzle 320 and the air inlet duct 310 are located on adjacent sides of the bellows 300, respectively. The cross-section of the nozzle 320 gradually decreases along the air outlet direction, so that the air outlet 321 is slit-shaped. The airflow entering the bellows 300 from the air inlet duct 310 slowly converges in the nozzle 320 and is blown out from the air outlet 321. The slit-shaped air outlet 321 can limit the diffusion angle of the airflow, thereby forming a directional linear airflow that precisely acts on the tab clearance area.

[0038] In some preferred embodiments, a flow equalization plate 330 is provided inside the wind box 300. The flow equalization plate 330 has a plurality of flow equalization holes 331. The plurality of flow equalization holes 331 can equalize and rectify the airflow entering the wind box 300 and then blow it out evenly from the air outlet 321. This can improve the uniformity of airflow distribution, reduce turbulence, and enhance the stability of the air flotation support. Moreover, the flow equalization plate 330 can also improve the overall structural strength of the wind box 300.

[0039] Specifically, there are two flow equalization plates 330. One flow equalization plate 330 is perpendicular to the air inlet duct 310 and close to the air inlet duct 310, while the other flow equalization plate 330 is located inside the air nozzle 320.

[0040] The flow equalization plate 330 near the air inlet duct 310 initially diverts the high-pressure airflow entering the air box 300 from the air inlet duct 310 through its flow equalization holes 331, reducing the intensity of airflow turbulence. The flow equalization plate 330 located in the air nozzle 320 performs secondary equalization on the airflow about to be blown out of the air outlet 321 through its flow equalization holes 331, thereby eliminating the velocity differences caused by the internal structure of the air box 300 or the inertia of the airflow and ensuring the uniformity of the airflow velocity blown out of the air outlet 321.

[0041] Positionally, the air inlet duct 310 is located at the bottom of the air box 300, and the air outlet 321 is located on one side of the air box 300. This allows the airflow to rise evenly from the bottom of the air box 300. Under the effect of gravity settling, the intensity of airflow turbulence is reduced. Moreover, the bottom air inlet and the side air outlet form a vertical airflow path, which avoids the airflow swirling and causing vortices to form inside the air box 300, further improving the uniformity of the airflow.

[0042] Reference Figure 1 This utility model embodiment also provides a climbing mechanism, including two wall plates 500 and a plurality of climbing guide roller groups 600 disposed between the two wall plates 500. The aforementioned air flotation nozzle structure is disposed between the two wall plates 500. The two mounting plates 210 of the air flotation nozzle structure are respectively installed on the inner side of the two wall plates 500, so as not to affect the original structure of the climbing mechanism and to facilitate the installation of the air flotation nozzle structure.
