Description

Technical Field

[0001] This utility model relates to the field of battery processing technology, and in particular to a laser dust removal mechanism for battery casings. Background Technology

[0002] The casing (e.g., aluminum casing) is prone to static electricity during production due to the properties of aluminum and the dry conditions of the production environment. Furthermore, static electricity has an adsorption capacity, attracting suspended dust, fibers from workers' clothing, and other foreign matter from the environment. If this dust and foreign matter adheres to the aluminum casing, it may negatively impact the performance and safety of the lithium battery. Therefore, dust removal from the casing is a crucial step in battery manufacturing.

[0003] In existing technologies, operators typically use methods such as blowing air, brushing, or washing to remove dust from the casing. These methods have low efficiency and low cleanliness, while also increasing labor costs and reducing work efficiency, making it difficult to meet the current industrial production demand for automation.

[0004] Therefore, there is an urgent need to design a laser dust removal mechanism for battery casings to solve the above technical problems. Utility Model Content

[0005] The purpose of this invention is to propose a laser dust removal mechanism for battery casings, which can improve work efficiency, enhance the cleanliness of battery casings, save labor costs, and meet the automation needs of industrial production.

[0008] Frame;

[0009] A first drive assembly, the fixed end of which is connected to the frame;

[0010] A dust removal fixture is connected to the drive end of the first drive assembly. The dust removal fixture includes an air blowing port and an air suction port. The first drive assembly can drive the dust removal fixture to approach the battery housing and place the battery housing between the air blowing port and the air suction port.

[0011] A laser is disposed on one side of the dust removal fixture, and the laser beam emitted by the laser can illuminate the battery casing.

[0012] As an optional technical solution for a laser dust removal mechanism for battery casings, the air blowing port is located below the air intake port, and the air blowing port and the air intake port are directly opposite each other.

[0013] As an optional technical solution for a laser dust removal mechanism for battery casings, the dust removal fixture further includes an air blowing component and an air suction component, wherein the air blowing component is connected to the air blowing port and the air suction component is connected to the air suction port.

[0014] As an optional technical solution for a laser dust removal mechanism for battery casings, the laser dust removal mechanism for battery casings further includes a nitrogen source, which is connected to the end of the air blowing assembly away from the air blowing port.

[0015] As an optional technical solution for a battery casing laser dust removal mechanism, the battery casing laser dust removal mechanism further includes a connecting plate, and multiple dust removal fixtures are provided. One side of the connecting plate is connected to all of the multiple dust removal fixtures, and the other side of the connecting plate is connected to the driving end of the first driving component.

[0016] As an optional technical solution for a laser dust removal mechanism for battery casings, the laser dust removal mechanism for battery casings further includes a connector, one end of which is connected to one of the two adjacent dust removal fixtures, and the other end of which is connected to the other dust removal fixture.

[0017] As an optional technical solution for a laser dust removal mechanism for battery casings, the laser dust removal mechanism for battery casings further includes a first base and a second drive assembly.

The third drive assembly is disposed on the second base and is drivenly connected to the first base to drive the first base to move along a first direction.

[0020] As an optional technical solution for a laser dust removal mechanism for battery casings, a second displacement sensor is provided on the second base, which is configured to detect the displacement of the first base.

[0021] The beneficial effects of this utility model include at least the following:

[0022] This utility model provides a laser dust removal mechanism for battery casings. The mechanism includes a frame, a first drive assembly, a dust removal fixture, and a laser. The fixed end of the first drive assembly is connected to the frame, and the driving end is connected to the dust removal fixture. The dust removal fixture includes an air blowing port and an air suction port. The first drive assembly drives the dust removal fixture closer to the battery casing and positions the battery casing between the air blowing port and the air suction port. The laser is positioned on one side of the dust removal fixture, and the laser beam emitted by the laser can irradiate the battery casing.

[0023] In the above process, after the battery casing is transported to the dust removal position of the laser dust removal mechanism, the driving end of the first driving component extends and drives the dust removal fixture to move towards the battery casing, placing the battery casing between the air blowing port and the air suction port of the dust removal fixture. The laser emits a laser beam and irradiates the battery casing, thereby removing contaminants from the battery casing. Specifically, the laser beam irradiates the surface of the battery casing, and through a series of physical and chemical reactions, removes contaminants (such as dust, oil, etc.) from the surface of the battery casing. During this process, the energy of the laser beam is absorbed by the surface of the battery casing, causing a rapid increase in local temperature, which in turn triggers reactions such as evaporation, combustion, or decomposition of the contaminants. The air blowing port can blow away the contaminants, and the air suction port can promptly suck away the contaminants, thereby improving the efficiency of dust removal. Compared with the dust removal methods in the prior art, the method of using a laser to emit a laser beam to remove dust from the battery casing in this invention can improve the cleanliness of the battery casing, increase work efficiency, save labor costs, reduce human intervention, and increase the degree of automation, thus meeting the automation needs of industrial production.

[0036] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0037] This embodiment provides a laser dust removal mechanism for battery casings, which can improve work efficiency, increase the cleanliness of battery casings, save labor costs, and meet the automation needs of industrial production.

[0038] like Figures 1-2 As shown, the battery casing laser dust removal mechanism mainly includes a frame 100, a first drive assembly 200, a dust removal fixture 300, and a laser 400. The fixed end of the first drive assembly 200 is connected to the frame 100, and the drive end of the first drive assembly 200 is connected to the dust removal fixture 300. The dust removal fixture 300 includes an air blowing port 310 and an air suction port. The first drive assembly 200 can drive the dust removal fixture 300 close to the battery casing 10 and place the battery casing 10 between the air blowing port 310 and the air suction port. The laser 400 is disposed on one side of the dust removal fixture 300, and the laser beam 410 emitted by the laser 400 can irradiate the battery casing 10.

[0039] Based on the above design, in this embodiment, when the battery casing 10 is transferred to the dust removal position of the battery casing laser dust removal mechanism, the driving end of the first driving component 200 extends and drives the dust removal fixture 300 to move towards the battery casing 10, so that the battery casing 10 is placed between the air blowing port 310 and the air suction port of the dust removal fixture 300. The laser 400 can emit a laser beam 410 and irradiate the battery casing 10, thereby removing contaminants from the battery casing 10. Specifically, the laser beam 410 irradiates the surface of the battery casing 10, and through a series of physical and chemical reactions, removes contaminants (such as dust, oil, etc.) from the surface of the battery casing 10. In this process, the energy of the laser beam 410 is absorbed by the surface of the battery casing 10, causing the local temperature to rise rapidly, thereby triggering reactions such as evaporation, combustion, or decomposition of contaminants. The air blowing port 310 can blow away contaminants, and the air suction port can promptly suck away contaminants, thereby improving the efficiency of dust removal. Compared with existing dust removal methods, the method of using a laser 400 to emit a laser beam 410 to remove dust from the battery casing 10 in this embodiment can improve the cleanliness of the battery casing 10, increase work efficiency, save labor costs, reduce human intervention, and improve the degree of automation, so as to meet the needs of industrial production for automation.

[0040] Optionally, in this embodiment, the blowing port 310 is located below the suction port, and the blowing port 310 and the suction port are directly opposite each other. The blowing port 310 being positioned below generates an upward airflow, disturbing contaminants on the surface of the battery casing 10, making them easier to evaporate or burn with the laser. Simultaneously, the suction port being positioned above allows for the timely removal of the generated air mass (containing contaminants and vaporized substances), preventing it from remaining on or re-adhering to the surface of the battery casing 10, thereby improving dust removal efficiency. Furthermore, the directly opposite blowing port 310 and suction port create a more uniform airflow field, covering the entire surface of the battery casing 10, ensuring consistent dust removal performance and improving dust removal quality. The presence of this airflow field reduces the direct thermal impact of the laser on the surface of the battery casing 10, thus preventing damage to the battery casing 10 to some extent.

[0041] like Figure 1 As shown, the dust removal fixture 300 in this embodiment also includes an air blowing assembly 320, an air suction assembly 330 and a nitrogen source. The air blowing assembly 320 is connected to the air blowing port 310, the air suction assembly 330 is connected to the air suction port, and the nitrogen source is connected to the end of the air blowing assembly 320 away from the air blowing port 310.

[0042] Nitrogen is an inert gas with stable chemical properties and does not readily react with other substances. During laser dust removal, the air outlet 310 blows out nitrogen gas, which effectively isolates the air and prevents the battery casing 10 from reacting with oxygen at high temperatures. This avoids oxidation of the battery casing 10, enhances its protection, and improves product yield.

[0043] Optionally, the blowing assembly 320 in this embodiment can be configured as a blowing pump, and the suction assembly 330 can be configured as a suction pump.

[0044] like Figure 1 As shown, in this embodiment, the battery casing laser dust removal mechanism also includes a connecting plate 500, and multiple dust removal fixtures 300 are provided. One side of the connecting plate 500 is connected to multiple dust removal fixtures 300, and the other side of the connecting plate 500 is connected to the driving end of the first driving component 200.

[0045] The connecting plate 500 integrates multiple dust removal fixtures 300, improving integration and facilitating the driving action of the first driving component 200, ensuring the relative positions of the multiple dust removal fixtures 300 remain unchanged. Optionally, in this embodiment, two or three equal numbers of dust removal fixtures 300 can be provided, and the multiple dust removal fixtures 300 are arranged at equal intervals along a first direction, with each dust removal fixture 300 corresponding to a battery housing 10. The first driving component 200 can drive the connecting plate 500 to enable the multiple dust removal fixtures 300 to move simultaneously toward the battery housing 10, improving dust removal efficiency. The first direction is... Figure 1 The X-axis direction in the diagram.

[0046] Furthermore, the battery casing laser dust removal mechanism in this embodiment also includes a connector 340. One end of the connector 340 is connected to one of the two adjacent dust removal fixtures 300, and the other end of the connector 340 is connected to the other dust removal fixture 300. In other words, the two adjacent dust removal fixtures 300 are connected by the connector 340, thereby improving the stability and reliability of the dust removal fixtures 300 and increasing the integration of the battery casing laser dust removal mechanism. Optionally, the connector 340 is connected to the dust removal fixture 300 by welding.

[0047] Optionally, the first drive component 200 in this embodiment can be configured as a cylinder, and the number of cylinders is not limited.

[0048] like Figures 1-2As shown, in this embodiment, the battery casing laser dust removal mechanism further includes a first base 600 and a second drive assembly 610. The second drive assembly 610 is disposed on the first base 600 and is drivenly connected to the laser 400 to drive the laser 400 closer to or further away from the dust removal fixture 300. The second drive assembly 610 can drive the first base 600 to move along a second direction, thereby enabling the laser 400 to move closer to or further away from the dust removal fixture 300, so as to change the focal length of the laser 400 according to different models of battery casings 10, thereby improving dust removal efficiency. The second direction is... Figure 1 The Y-axis direction in the diagram.

[0049] Furthermore, in this embodiment, a first displacement sensor 420 is provided on the laser 400. The first displacement sensor 420 is configured to detect the distance between the laser 400 and the battery casing 10. Simultaneously, the battery casing laser dust removal mechanism also includes a PLC controller (not shown in the figure). The first displacement sensor 420 can feed back the detected distance signal between the laser 400 and the battery casing 10 to the PLC controller in real time. The PLC controller controls the second drive assembly 610 to drive the first base 600 to move based on this signal, thereby changing the focal length of the laser 400.

[0050] Optionally, the laser 400 in this embodiment can be a commercially available gas laser 400, such as a nitrogen molecular laser. Its working principle and specific structure will not be described in detail here.

[0051] like Figures 1-2 As shown, the battery casing laser dust removal mechanism also includes a second base 700 and a third drive assembly 710. The third drive assembly 710 is disposed on the second base 700 and is drivenly connected to the first base 600 to drive the first base 600 to move along a first direction. This causes the laser 400 on the first base 600 to move from one dust removal position of a dust removal fixture 300 to the next dust removal position of a dust removal fixture 300, so as to perform laser dust removal on the battery casing 10 in the next dust removal fixture 300. In this way, the battery casing laser dust removal mechanism only needs to set up one laser 400 to complete the dust removal work of multiple battery casings 10, saving costs and making the structure of the battery casing laser dust removal mechanism simple and easy to assemble.

[0052] Furthermore, in this embodiment, a second displacement sensor 720 is provided on the second base 700. The second displacement sensor 720 is configured to detect the displacement of the first base 600. The second displacement sensor 720 can feed back the displacement signal of the first base 600 to the PLC controller. The PLC controller controls the action of the third drive component 710 according to the signal to prevent the first base 600 from moving excessively or even derailing.

[0053] Optionally, both the second drive component 610 and the third drive component 710 in this embodiment can be configured as motors.

[0054] Optionally, the first displacement sensor 420 and the second displacement sensor 720 in this embodiment can both be set as commonly available displacement sensors on the market, and their specific structures and working principles will not be described in detail here.

[0055] like Figure 1 As shown, in this embodiment, the battery casing laser dust removal mechanism also includes an anemometer 800, which is mounted on the frame 100 and used to detect the wind speed of the nitrogen gas blown out of the air outlet 310, ensuring that the airflow speed is within a suitable range. The airflow direction in this embodiment is... Figure 1 The Z-axis direction is the height direction of the laser dust removal mechanism for the battery casing. A suitable airflow velocity can more effectively blow contaminants away from the surface of the battery casing 10 and carry them into the suction assembly 330, thereby improving the dust removal effect. If the airflow velocity is too low, it may not be able to effectively blow away contaminants; if the airflow velocity is too high, the contaminants may be scattered and cannot be effectively collected.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention.
