[0018] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] See Figure 1-3 As shown, this embodiment provides a cell dust removal device, including a frame 10, a dust removal mechanism, and a drive mechanism, wherein: The frame 10 serves as the basic carrier, stably supporting the dust removal mechanism and drive mechanism, and is adaptable to the installation environment of the workshop. The frame 10 is equipped with a tray 60 for supporting the workpiece 61 to be dusted. In this embodiment, the workpiece 61 is a battery cell and a battery cell clamp. The battery cell is placed inside the battery cell clamp, and multiple battery cell clamps are placed sequentially on the tray 60.

[0020] The dust removal mechanism can move closer to or further away from the tray 60. The dust removal mechanism includes a housing 20, an air knife 32 assembly 30, and a dust collection assembly. The housing 20 has a cavity 21. The end of the housing 20 facing the tray 60 has an opening 22. When the dust removal mechanism moves to a preset position relative to the tray 60, the opening 22 covers the tray 60, so that the cavity 21 and the tray 60 enclose a sealed chamber. The air knife 32 assembly 30 is located inside the housing 20 and can move back and forth along a preset path. During the movement, the air knife 32 assembly 30 blows airflow toward the workpiece 61 to be dusted to sweep away the dust. The dust collection assembly is connected to the housing 20 and communicates with the sealed chamber to remove the dust in the sealed chamber during the blowing process of the air knife 32 assembly 30. In the embodiments provided in this application, in order to solve the problems of easy diffusion and incomplete dust removal in open environments, a sealed chamber is formed by the box 20 and the tray 60, so that the dust collection component can form a stable negative pressure. The dust generated by the air knife 32 is confined in the closed space and will not diffuse to the external working environment, thus avoiding dust pollution of the workshop air or adhesion to other untreated workpieces 61. This not only achieves efficient dust removal, but also avoids the harm of long-term inhalation by workers.

[0021] See Figure 4-5 As shown, in this embodiment, the air knife 32 component 30 moves back and forth along a preset path, which can cover the surface, gaps and other key areas of all battery cells and battery cell clamps on the tray 60. It ensures that the attached dust is fully blown away by repeated blowing, avoiding the problems of limited blowing range, dead corners or incomplete blowing of the fixed air knife 32. At the same time, the dust collection component works synchronously to remove the suspended dust blown up in time, preventing the dust from floating in the chamber and re-attaching to the workpiece 61, thus significantly improving the dust removal efficiency.

[0022] The drive mechanism is used to move the dust removal mechanism closer to or further away from the tray 60. When the drive mechanism moves the dust removal mechanism away from the tray 60, the tray 60 can move or the battery cells on the tray 60 can be moved. When the drive mechanism moves the dust removal mechanism closer to the tray 60 to a preset position, the outer shell completely covers the tray 60 to form a sealed chamber, providing a sealed environment for negative pressure adsorption.

[0023] See Figure 4-5 As shown, in some embodiments of this application, in order to achieve the reciprocating movement of the air knife 32 assembly 30, the air knife 32 assembly 30 includes a first driving member 31 and an air knife 32. The first driving member 31 is located on the side of the housing 20 facing the receiving cavity 21. The air knife 32 is connected to the output end of the first driving member 31. The first driving member 31 drives the air knife 32 to reciprocate along a preset path. The air knife 32 is used to blow airflow onto the workpiece 61. The blowing direction of the air knife 32 faces the workpiece 61, and the air knife 32 and the workpiece 61 always maintain a preset safe distance to avoid mechanical collision causing damage to the battery cell. The air knife 32 assembly 30 is integrated into the side of the housing 20 facing the receiving cavity 21 and can be raised and lowered synchronously with the housing 20. It should be noted that the core improvement of this application lies in the overall structural design of the dust removal device and the coordinated cooperation of each component. The air knife 32 itself is an existing mature component, and its related blowing working principle is well known to those skilled in the art, so it will not be elaborated here.

[0024] See Figure 5-7 As shown, in one feasible embodiment, the first driving member 31 includes a driving unit (not shown in the figure), a first slide rail 311, and a first slider 312. The first slide rail 311 extends along a preset direction, and the first slider 312 slides in cooperation with the first slide rail 311. The air knife 32 is mounted on the first slide rail 311 via the first slider 312, and the driving unit drives the first slider 312 to move on the first slide rail 311. In this embodiment, the first slide rail 311 is a linear slide rail, and the driving unit is a motor. Although the position of the motor is not shown in the figure, it can be arranged according to common knowledge. The air knife 32 moves back and forth along the linear slide rail, maintaining a stable moving speed and positional accuracy.

[0025] See Figure 6-7 As shown, in this embodiment, the air knife 32 assembly 30 also includes a cable chain 33 and a cable chain plate 34. The cable chain plate 34 is connected to the housing 20. The fixed end of the cable chain 33 is fixed to the cable chain plate 34, and the movable end of the cable chain 33 is connected to the air knife 32. The cable chain 33 extends and retracts synchronously with the movement of the air knife 32. The cable chain 33 is used to store the connecting cables and / or air pipes of the air knife 32. When the air knife 32 moves back and forth, it will drive its own air supply pipe, control line, and signal line to move synchronously. The cable chain 33 follows the movement of the air knife 32 by its own extension and retraction, avoiding cable tangling and pulling, and can organize the cable layout and reduce maintenance difficulty.

[0026] See Figure 6-7 As shown, in some embodiments of this application, to enhance the stability of the air knife 32's movement, the air knife 32 assembly 30 further includes a slide rod 35 and a second slider 36. The slide rod 35 is parallel to and vertically arranged with the first slide rail 311, and the second slider 36 is sleeved on the slide rod 35. The air knife 32 is fixedly connected to the second slider 36. When the air knife 32 moves on the first slide rail 311, it is also precisely guided by the slide rod 35, limiting the movement trajectory of the air knife 32 and preventing the air knife 32 from deviating, shaking, or jamming during reciprocating movement, thereby improving the movement accuracy of the air knife 32. In this embodiment, limiting portions 37 are provided at both ends of the slide rod 35 to prevent the air knife 32 from impacting the inner wall of the housing 20, thus improving operational stability.

[0027] See Figure 2 and Figure 4 As shown, in this embodiment, the dust removal mechanism can be set as one or multiple. The synchronous lifting and lowering of the mechanism can be driven by the first driving component to improve the dust removal efficiency and increase the number of workpieces 61 that can be dusted in a single operation. However, considering the weight of the dust removal mechanism, it is not advisable to set too many synchronously moving dust removal mechanisms. As a better approach, two dust removal mechanisms are provided and arranged symmetrically. A connecting plate 23 is installed between the two dust removal mechanisms. The connecting plate 23 connects the two dust removal mechanisms into a whole so that the two dust removal mechanisms can move synchronously.

[0028] See Figure 1 As shown, in some embodiments of this application, the driving mechanism includes a cylinder 50 and a cylinder connecting plate 51. The cylinder connecting plate 51 is located between two dust removal mechanisms, and the cylinder 50 is located on the top of the frame 10. The output end of the cylinder 50 is connected to the cylinder connecting plate 51 by adsorption. Two cylinders 50 are provided, symmetrically arranged on the top of the frame 10, synchronously driving the cylinder connecting plate 51 to drive the two dust removal mechanisms to rise and fall. The power output of the two cylinders 50 is uniform, which can avoid shaking when the dust removal mechanism rises and falls, and the operation is more stable. The cylinder 50 and the cylinder connecting plate 51 can be fixedly connected, but as a better method, the output end of the cylinder 50 is connected to the cylinder connecting plate 51 by adsorption. If negative pressure adsorption is used, flexible connection and shock buffering can be achieved, avoiding vibration when the dust removal mechanism reaches the preset position, which could cause cell displacement or secondary dust adhesion.

[0029] See Figure 1As shown, in order to ensure precise guidance of the dust removal mechanism during lifting and lowering, and to ensure precise closing of the dust removal mechanism with the tray 60 when it descends to the preset position, thereby ensuring the airtightness of the sealed chamber, in some embodiments of this application, the drive mechanism further includes a second slide rail 52 and a third slider 53. The second slide rail 52 is arranged on the frame 10 along a direction perpendicular to the bearing surface of the tray 60, and the third slider 53 is fixed to the housing 20 and slides in cooperation with the second slide rail 52. The second slide rail 52 is arranged along the four inner edges of the frame 10, and the housing 20 is connected to the third slider 53. When the cylinder 50 drives the dust removal mechanism to lift and lower, the third slider 53 cooperates with the second slide rail 52 to achieve precise guidance. No matter how heavy the dust removal mechanism is, it can always move smoothly along a direction perpendicular to the bearing surface of the tray 60, improving the smoothness of movement and avoiding misalignment between the opening 22 and the tray 60, thereby achieving precise closing.

[0030] See Figure 1-2 As shown in the figure, in this embodiment, the dust collection assembly includes multiple dust collection pipes 40 and a negative pressure mechanism (not shown). The housing 20 has multiple dust collection ports 24 communicating with the receiving cavity 21. Each dust collection port 24 is connected to one end of a corresponding dust collection pipe 40. The other ends of the dust collection pipes 40 converge and connect to the suction end 41 of the negative pressure mechanism. The dust collection ports 24 are positioned opposite to the air knife 32, forming a directional airflow circuit. The airflow blown by the air knife 32 can send dust to the dust collection ports 24, allowing the blown dust to be quickly adsorbed by the negative pressure, improving the suction efficiency. In the embodiment provided in this application, the housing 20 has multiple dust collection ports 24. Combined with the reciprocating movement of the air knife 32, this achieves full coverage of the sealed chamber. The multiple dust collection ports 24 can correspond to multiple rows of battery cells on the tray 60, ensuring that each group of workpieces 61 has a negative pressure adsorption point around it, avoiding dead zones in the suction process.

[0031] See Figure 2 As shown, furthermore, the suction pipes 40 corresponding to the multiple suction ports 24 can be interconnected. After the multiple suction pipes 40 converge, they can be connected to the negative pressure mechanism through a main pipe 42, simplifying the pipeline layout and reducing installation difficulty and space occupation. When there are two dust removal mechanisms, there is a certain space between the two dust removal mechanisms. The suction pipes 40 of the two dust removal mechanisms can be laid in this space, and after the suction pipes 40 of the two dust removal mechanisms converge, each is connected to the negative pressure mechanism through a main pipe 42, avoiding the pipeline mess caused by multiple channels individually connecting to the negative pressure mechanism. It should be noted that the main pipe 42 should be a telescopic pipe with extra length so that it can adaptably extend and retract when the dust removal mechanism is raised and lowered. In addition, in order to be compatible with different dust removal scenarios and improve versatility, the number, position and diameter of the suction ports 24 can be flexibly adjusted according to the battery cell specifications and tray 60 size, which is not limited here.

[0032] See Figure 1 and Figure 3 As shown, due to the weight of the battery cells, manual transfer is time-consuming and labor-intensive, and secondary dust contamination may occur during the transfer process. In one feasible embodiment, the frame 10 is also equipped with a conveying mechanism 62. The conveying mechanism 62 is arranged along a preset conveying direction and is used to convey the pallet 60 carrying the workpiece 61 to be dusted to the preset working position of the frame 10. In this embodiment, the conveying mechanism 62 is a conventional conveyor line on the production line. The dust removal device is used in conjunction with the conveyor line for battery cell transportation. The pallet 60 is automatically transported directly by the conveying mechanism 62 without manual intervention, improving transfer efficiency. It can also be adapted to the production process, and the dust removal device can be set up at various stages where battery cell dust removal is required to achieve collaborative operation. Specifically, when the conveying mechanism 62 reaches the preset working position of the frame 10, it stops, the dust removal mechanism descends to cover the pallet 60, and removes dust from the battery cells. After dust removal is completed, the dust removal mechanism rises, and the conveying mechanism 62 transports the pallet 60 and the battery cells on the pallet 60 to the production line of the subsequent process, reducing the waiting time between processes and improving the overall production line capacity.

[0033] Based on the above embodiments, the working principle of the battery cell dust removal device provided by this utility model is as follows: When the conveying mechanism 62 transports the tray 60 and the battery cells on the tray 60 to the preset working position of the frame 10, the cylinder 50 drives the two dust removal mechanisms to descend to the preset position. At this time, the box 20 covers the tray 60, and the dust removal mechanism and the tray 60 form a sealed chamber. The drive unit drives the air knife 32 to move back and forth along the first slide rail 311 and the guide rod. During the movement, the air knife 32 continuously blows away the dust on the battery cells. At the same time, the negative pressure mechanism sucks away the blown-out dust through multiple suction ports. After the dust removal is completed, the cylinder 50 drives the dust removal mechanism to rise, and the conveying mechanism 62 moves the dust-removed battery cells and the tray 60 to the next process.

[0034] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
