Description

Technical Field

[0001] This application relates to the field of battery electrode production technology, and in particular to a wiping roller device and an electrode coating equipment. Background Technology

[0002] When a coating machine produces electrodes, the back roller, which acts as a support roller, is in constant contact with the electrodes. As the solvent evaporates, solutes are continuously released and turn into dust that adheres to the back roller. This makes the cleanliness of the back roller crucial to the stability of the equipment and the quality of electrode production.

[0003] In related technologies, the commonly used cleaning solution involves cleaning the back rollers using a wiping roller device and collecting dust using a dust collection box. However, this solution requires periodic disassembly and reassembly of the dust collection box for manual cleaning, which not only increases labor costs but also affects the continuous production efficiency of the production line.

[0041] In related technologies, the commonly used cleaning solution involves cleaning the back rollers using a wiping roller device and collecting dust using a dust collection box. However, this solution requires periodic disassembly and reassembly of the dust collection box for manual cleaning, which not only increases labor costs but also affects the continuous production efficiency of the production line.

[0042] To address the aforementioned issues, this application provides a wiping roller device that can collect dust to the closed end of the box via a scraper, thereby centrally removing dust without manual operation and improving production efficiency.

[0043] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0044] See Figures 1 to 3 This application provides an embodiment of a wiping roller device, including a box body 1, a scraper 2, a drive mechanism 3, and a dust suction pipe assembly 4. One end of the box body 1 is a closed end 10, and the other end has an opening 11. The scraper 2 is disposed at the opening 11 along the extension direction of the opening 11. The drive mechanism 3 is connected to the box body 1 and is used to drive the box body 1 to rotate to an inclined state so that the closed end 10 is lower than the opening 11. One end of the dust suction pipe assembly 4 is close to the closed end 10 and communicates with the inside of the box body 1, and is used to suck up the dust concentrated at the closed end 10.

[0045] In this embodiment, the box 1 has multiple functions: it can serve as a support for mounting and supporting the scraper 2, and it can also serve as a dust collection container to collect dust. Furthermore, the box 1 can be a long, grooved structure that extends axially along the coating roller 7, fully covering the roller surface to ensure that the dust and waste removed by the scraper are quickly collected.

[0046] During the wiping roller operation, the drive mechanism 3 drives the housing 1 to rotate to an inclined state, so that the closed end 10 is lower than the opening 11, i.e., the closed end 10 is located below the opening 11. The dust scraped by the scraper 2 can be deposited obliquely along the opening 11 to the closed end 10, preventing dust overflow and facilitating centralized collection. Then, in conjunction with the dust suction pipe assembly 4, the dust deposited in the closed end 10 is sucked away, achieving centralized dust removal, reducing labor costs, and improving production efficiency.

[0047] As an optional embodiment, see Figure 1 and Figure 2 The drive mechanism 3 includes a support 30, a driver 31 and a rotating shaft 32. The rotating shaft 32 is connected to the housing 1 along the extension direction of the opening 11. The rotating shaft 32 is rotatably connected to the support 30. One end of the driver 31 is rotatably connected to the support 30 and the other end is rotatably connected to the rotating shaft 32, and is used to drive the rotating shaft 32 to rotate.

[0048] In this embodiment, the actuator 31 serves as a power source, providing linear reciprocating motion, such as telescopic motion. The support 30 serves as a fixed support structure, rotatably connected to one end of the actuator 31 (e.g., the cylinder end of a cylinder) via a hinge or pin. The rotating shaft 32 is fixedly connected to the housing 1, and rotatably connected to the other end of the actuator 31 (e.g., the piston rod end of a cylinder). The telescopic motion of the actuator 31 is converted into the rotational motion of the rotating shaft 32, thereby driving the housing 1 to rotate. Taking the actuator 31 as a cylinder as an example, the specific driving process is explained as follows:

[0049] Cylinder extension: The piston rod pushes outward, pushing the rotating shaft 32. Since the other end of the cylinder is hinged to the support 30, the cylinder as a whole will rotate around the support 30, while driving the rotating shaft 32 to rotate around its own axis.

[0050] Cylinder retraction: The piston rod is pulled inward, which in turn pulls the rotating shaft 32 in the opposite direction, causing the rotating shaft 32 to rotate in the opposite direction.

[0051] As a preferred embodiment, see Figure 1 and Figure 2 The support 30 includes a first seat 300 arranged perpendicular to the extension direction of the rotating shaft 32, and a second seat 301 perpendicularly connected to the first seat 300; the rotating shaft 32 is rotatably connected to the first seat 300, and the driver 31 is rotatably connected to the second seat 301.

[0052] In this embodiment, the first seat 300 and the second seat 301 perform different functions to jointly ensure the stable rotation of the rotating shaft 32 and the effective power transmission of the driver 31 (such as a cylinder, motor, etc.).

[0053] The first base 300 supports the rotating shaft 32 and provides a center of rotation. The first base 300 is arranged along an extension direction perpendicular to the rotating shaft 32, and is typically a vertically mounted plate / block structure. The rotating shaft 32 can be rotatably connected to the first base 300 via bearings, bushings, or hinges, allowing the rotating shaft 32 to rotate freely about its axis.

[0054] The second seat 301 fixes the driver 31 and transmits driving force. The second seat 301 is perpendicularly connected to the first seat 300 to form, for example, an L-shaped or T-shaped structure, together forming a rigid support frame. The driver 31 is rotatably connected to the second seat 301, allowing the driver 31 to swing within a certain angle.

[0055] As a preferred embodiment, see Figure 1 and Figure 2 The drive mechanism 3 also includes a first connecting shaft 33, which is arranged along the extension direction of the rotating shaft 32. One end of the first connecting shaft 33 is fixedly connected to the support 30, and the other end is rotatably connected to the driver 31.

[0056] In this embodiment, the first connecting shaft 33 is arranged along the extension direction (axial direction) of the rotating shaft 32, forming an auxiliary transmission shaft parallel to the rotating shaft 32. One end of the first connecting shaft 33 is rigidly fixed to the support 30 to ensure axial positioning stability. The other end can be connected to the driver 31 using a rotating pair such as a pin or a spherical bearing to prevent mechanism jamming caused by motion interference.

[0057] As a preferred embodiment, see Figure 1 and Figure 2The drive mechanism 3 also includes a second connecting shaft 34, which is arranged perpendicular to the extension direction of the rotating shaft 32. One end of the second connecting shaft 34 is fixedly connected to the rotating shaft, and the other end is rotatably connected to the driver 31.

[0058] In this embodiment, the second connecting shaft 34 is arranged perpendicular to the rotating shaft 32 and serves as a power transmission medium between the driver 31 (such as a cylinder or motor) and the rotating shaft 32, converting the linear or rotary motion of the driver 31 into the rotational torque of the rotating shaft 32.

[0059] As an optional embodiment, the vacuum tube assembly 4 includes a first vacuum tube 40, a plurality of branch tubes 41, and a second vacuum tube 42. The first vacuum tube 40 is arranged along the extension direction of the opening 11, the plurality of branch tubes 41 are arranged at intervals along the extension direction of the first vacuum tube 40, and each branch tube 41 is arranged perpendicular to the first vacuum tube 40. The two ends of the branch tube 41 are respectively connected to the inside of the box 1 and the first vacuum tube 40. The second vacuum tube 42 is connected to the first vacuum tube 40.

[0060] In the embodiments of this application, see Figure 1 and Figure 2 The first suction pipe 40 is the main suction pipe, serving as the core suction channel. It is set along the extension direction of the opening 11 and is responsible for collecting the dust sucked in by each branch pipe 41 and transporting it to the second suction pipe 42. The long straight pipe design ensures uniform airflow distribution.

[0061] Branch pipe 41, acting as a branch suction pipe, is vertically connected to the first suction pipe 40 and the interior of the housing 1, forming multiple local suction points, expanding the suction coverage area, and improving dust collection efficiency. Furthermore, the multiple branch pipes 41 are spaced apart to avoid airflow interference and specifically adsorb dust from different areas.

[0062] The second suction pipe 42 is connected to the first suction pipe 40 as an output pipe, and the collected dust airflow is exported to the external dust collection device.

[0063] The embodiments of this application achieve efficient and comprehensive dust collection and transportation through a hierarchical pipeline design (branch pipe 41 → first suction pipe 40 → second suction pipe 42).

[0064] As a preferred embodiment, see Figure 1 The vacuum tube assembly 4 also includes a transition tube 43, which is arranged along the extension direction of the first vacuum tube 40. The second vacuum tube 42 is connected to the tube body of the transition tube 43, and the two ends of the transition tube 43 are respectively connected to the two ends of the first vacuum tube 40.

[0065] In this embodiment, the transition pipe 43 is configured in parallel with the first suction pipe 40 as an airflow integration pipe, forming a dual-channel structure to balance airflow pressure and reduce eddies or dust accumulation. Furthermore, as the access point for the second suction pipe 42, it optimizes airflow guidance and avoids insufficient local negative pressure caused by direct connection to the first suction pipe 40.

[0066] As a preferred embodiment, see Figure 4 The wiping roller device also includes a vacuum cleaner 5, which is connected to the end of the second suction pipe 42 away from the box 1 and is used to apply negative pressure to the second suction pipe 42.

[0067] In this embodiment, the vacuum cleaner 5 can generate a stable negative pressure through a fan or vacuum pump to provide a suction source for the entire vacuum tube assembly 4, ensuring that dust is efficiently sucked in and transported to the dust collection point.

[0068] Corresponding to the aforementioned application function implementation device embodiments, this application also provides an electrode coating device and corresponding embodiments.

[0069] See Figure 4 This application also provides an electrode coating apparatus, including a support 6 and a coating roller 7, the coating roller 7 being rotatably mounted on the support 6; and the aforementioned wiping roller device, the wiping roller device being movably mounted on the support 6, with the scraper 2 facing the coating roller 7.

[0070] The electrode coating equipment in this embodiment integrates roller wiping and coating, ensuring electrode quality. The scraper 2 of the roller wiping device acts directly on the surface of the coating roller 7, instantly removing residual slurry or dust from the roller surface and preventing foreign matter from transferring to the electrode and causing defects (such as scratches or dents). Furthermore, the roller wiping can be performed during production through the cooperation of the housing 1 and the dust suction pipe assembly 4, avoiding the reduction in labor costs and production efficiency caused by disassembling and reassembling the housing 1.

[0071] As an optional embodiment, the wiping roller device can move on the support 6 in a direction toward or away from the coating roller 7.

[0072] In this embodiment, the wiping roller device can move on the support 6 in a direction closer to or further away from the coating roller 7, adjusting the distance between the scraper 2 and the coating roller 7 so that the scraper 2 is attached to the coating roller 7, and the roller surface of the coating roller 7 is cleaned as the coating roller 7 rotates.
