Description

Technical Field

[0001] This utility model relates to the field of laser cleaning technology, specifically to a dust cover and a laser dust removal device. Background Technology

[0002] With the rapid development of the battery industry, the requirements for battery consistency are becoming increasingly stringent. To improve the efficiency of battery cleaning and save cleaning resources, laser cleaning is being used more and more widely. However, the laser cleaning process vaporizes the surface material of the battery, causing tiny particles to float in the air. If these particles are not removed in time, they can easily affect battery quality and pollute the workshop environment. Therefore, dust covers are usually required to remove the tiny particles generated during the laser cleaning process.

[0003] The dust covers provided in the relevant technologies are relatively large. Utility Model Content

[0004] The present invention provides a dust cover that can improve the technical problem of large dust cover volume in related technologies.

[0005] In a first aspect, an embodiment of the present invention provides a dust cover for use in a laser dust removal device. The dust cover includes a cover body, which has a working port, a first channel, and a second channel. The first channel is connected to the working port and is used to direct a laser beam from the working port to the workpiece to be processed. The second channel is connected to the working port so that dust from the workpiece to be processed can be sucked out from the working port.

[0006] In one embodiment, the enclosure body is further provided with a communicating cavity, the working port is disposed on the inner wall of the communicating cavity, and the first channel and the second channel are both connected to the communicating cavity.

[0007] By setting up a connecting cavity as a shared channel for the first and second channels, the connection structure between the first and second channels and the connecting cavity can be optimized, the mechanical stress between the first and second channels and the connecting cavity can be reasonably distributed, and the stress concentration generated when the first and second channels are directly connected can be reduced, thereby extending the service life of the dust cover.

[0008] In one embodiment, the end of the first channel away from the communicating cavity is connected to the second channel.

[0009] By connecting the end of the first channel to the second channel, the adsorption effect provided by the second channel is used to actively suck up the free dust in the first channel, preventing it from depositing in the channel, thereby protecting the cleanliness of the laser emitter and ensuring processing stability.

[0010] In one embodiment, the first channel includes a first connecting end near the communicating cavity, and the second channel includes a second connecting end near the communicating cavity, wherein the angle between the first connecting end and the second connecting end is greater than or equal to 15° and less than or equal to 45°.

[0011] By controlling the angle between the first connecting end and the second connecting end within a suitable range, the second channel can be easily connected to an external suction device, while the kinetic energy loss of the airflow when it enters the second channel through the connecting cavity is small, thereby ensuring a faster airflow speed and improving the efficiency of dust removal.

[0012] In one embodiment, the area of ​​the working port is less than or equal to the area of ​​the outlet of the second channel.

[0013] When the airflow passes through the smaller working port, the airflow velocity is faster, which more effectively carries away the dust generated by laser cleaning and draws the dust into the second channel, reducing the probability of dust escape.

[0014] In one embodiment, the dust cover further includes a light-transmitting element disposed within the first channel for allowing laser light to pass through.

[0015] By setting a light-transmitting element in the first channel, the laser can pass smoothly through the first channel to clean the battery, while the light-transmitting element can block dust from flowing through the first channel to the laser emitting device, reducing the probability of dust contaminating the laser emitting device.

[0016] In one embodiment, the thickness of the light-transmitting element is greater than or equal to 2 mm and less than or equal to 3 mm.

[0017] By controlling the thickness of the transparent adhesive within a suitable range, the transparent component can achieve good mechanical strength while maintaining a low weight, thereby reducing the difficulty of installing the dust cover.

[0018] Secondly, embodiments of this utility model provide a laser dust removal device, including a laser and a dust cover as described in the foregoing embodiments, wherein the working port of the dust cover is configured to face the battery; the laser is configured to correspond to the entrance of the first channel for emitting laser light to the battery.

[0019] In one embodiment, the laser dust removal device further includes a mounting base, and at least one of the dust cover and the laser is connected to the mounting base.

[0020] By providing a mounting base, at least one of the dust cover and the laser is given stable support. If the laser is connected to the mounting base, the base significantly improves the laser's stability, thereby ensuring the efficiency of laser cleaning. If the dust cover is connected to the mounting base, the base improves the dust cover's stability and reduces vibrations that may occur when suctioning dust.

[0021] In one embodiment, the laser dust removal equipment further includes a moving device connected to the mounting base for adjusting the position of the mounting base.

[0022] By connecting the mobile device to the mounting base, operators can dynamically adjust the position of the mounting base by controlling the mobile device, thereby adjusting the positions of the dust cover and the laser, significantly improving the process adaptability and operational efficiency of the laser dust removal equipment.

[0023] In one embodiment, the laser dust removal device further includes a processing station for carrying the battery, wherein the distance between the processing station and the working port is greater than or equal to 4 mm and less than or equal to 8 mm.

[0024] By controlling the distance between the processing station and the working port to maintain it within a suitable range, the airflow generated by the external suction equipment can effectively remove dust near the battery through the dust cover, thereby improving the dust removal effect.

[0025] In one embodiment, the laser dust removal device further includes a nitrogen supply component connected to the mounting base, the nitrogen supply component being used to supply nitrogen to the battery.

[0026] By setting up a nitrogen supply component and blowing nitrogen into the battery, the heat generated during laser cleaning of the battery surface is removed, while the laser output power and beam quality are improved, thereby increasing the cleaning efficiency of the battery.

[0027] The beneficial effects of the embodiments of this utility model are as follows:

[0028] In this embodiment of the invention, a working port, a first channel, and a second channel are provided on the cover. A laser can irradiate and clean the battery along the first channel, while the generated dust enters the second channel through the working port, thus achieving dust removal. The working port can simultaneously perform dust removal and suction, has low processing difficulty, and the dust cover does not need to be placed on the battery. This makes the dust cover structure in this embodiment of the invention compact, space-saving, and easy to install and maintain. It can also be adapted to various types or sizes of workpieces without affecting the rotation operation of the workpiece, thereby meeting the all-round cleaning needs of the workpiece and improving cleaning efficiency.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. In the present utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0042] In the dust cover provided by the relevant technology, the laser incident channel and the dust removal channel are independent of each other, and the opening of the laser incident channel facing the battery and the opening of the dust removal channel facing the battery are far apart, resulting in a large area of ​​the dust cover facing the battery, and ultimately a large volume of the dust cover.

[0043] Based on this, refer to Figure 1 and Figure 2 The first aspect of this utility model provides a dust cover 1, which is applied to a laser dust removal device 3. The dust cover 1 includes a cover body 11, which is provided with a working port 111, a first channel 112 and a second channel 113. The first channel 112 is connected to the working port 111 and is used to allow the laser to be directed from the working port 111 to the workpiece to be processed. The second channel 113 is connected to the working port 111 so that the dust at the workpiece to be processed can be sucked out from the working port 111.

[0044] The working port 111 serves both as a means for the laser to pass through and irradiate the workpiece to be processed, and as a means for external suction equipment to absorb dust through the second channel 113, thus protecting the cleanliness of the working environment. The first channel 112 and the second channel 113 can be two independent channels, or they can be formed by dividing a single channel into the first channel 112 and the second channel 113 by a partition. The shapes of the first channel 112 and the second channel 113 can be set according to actual needs, and this embodiment of the utility model does not limit this.

[0045] This embodiment of the invention features a working port 111, a first channel 112, and a second channel 113 on the cover 11. A laser can irradiate and clean the battery along the first channel 112, while the generated dust enters the second channel 113 through the working port 111, thus achieving dust removal. The working port can simultaneously perform dust removal and suction, reducing manufacturing difficulty. Furthermore, the dust cover 1 does not need to be placed over the battery, resulting in a compact structure, small footprint, and convenient installation and maintenance. It can also be adapted to various types and sizes of workpieces without affecting their rotation, thereby meeting the comprehensive cleaning needs of the workpieces and improving cleaning efficiency.

[0046] In one embodiment, reference is made to Figure 2 The cover 11 is also provided with a connecting cavity 114, and the working port 111 is located on the inner wall of the connecting cavity 114. The first channel 112 and the second channel 113 are both connected to the connecting cavity 114.

[0047] If the first channel 112 and the second channel 113 are connected only at the working port 111, the connection is usually thinner and stress concentration points are easily formed during welding or bonding. Long-term use may lead to weld cracking or sealing failure, affecting the performance of the dust cover 1.

[0048] Therefore, by setting the connecting cavity 114 as a channel shared by the first channel 112 and the second channel 113, this embodiment of the utility model can optimize the connection structure between the first channel 112, the second channel 113 and the connecting cavity 114, reasonably distribute the mechanical stress between the first channel 112, the second channel 113 and the connecting cavity 114, reduce the stress concentration generated when the first channel 112 and the second channel 113 are directly connected, and thus extend the service life of the dust cover 1.

[0049] In one embodiment, reference is made to Figure 3 The end of the first channel 112 that is away from the connecting cavity 114 is connected to the second channel 113.

[0050] During laser cleaning, the airflow may carry some dust into the first channel 112, causing contamination of the laser emitting device or affecting the quality of the laser beam. Therefore, in this embodiment of the invention, the end of the first channel 112 is connected to the second channel 113. With the adsorption effect provided by the second channel 113, the free dust in the first channel 112 is actively sucked up, preventing it from depositing in the channel, thereby protecting the cleanliness of the laser emitter and ensuring processing stability.

[0051] Specifically, when the external suction device draws air through the second channel 113, most of the airflow is discharged from the connecting cavity 114 through the second channel 113, while a small portion of the airflow flows to the first channel 112. Since in this embodiment, the end of the first channel 112 furthest from the connecting cavity 114 is connected to the second channel 113, a small portion of the airflow is also drawn into the second channel 113 through this connection, thereby achieving the extraction of dust from the first channel 112. This improves dust cleaning efficiency without the need for additional suction ports and reduces the probability of dust affecting laser cleaning.

[0052] In some alternative implementations, the first channel 112 and the second channel 113 are separated by a partition. In this case, a through hole can be provided only at the end of the partition away from the connecting cavity 114 to achieve communication between the first channel 112 and the second channel 113.

[0053] In one embodiment, the first channel 112 includes a first connecting end 1121 near the communicating cavity 114, and the second channel 113 includes a second connecting end 1131 near the communicating cavity 114. The angle between the first connecting end 1121 and the second connecting end 1131 is greater than or equal to 15° and less than or equal to 45°.

[0054] If the angle between the first connecting end 1121 and the second connecting end 1131 is less than 15°, the angle is too small, resulting in a relatively short overall distance between the first channel 112 and the second channel 113, which is not conducive to connecting the external suction device to the second channel 113. If the angle between the first connecting end 1121 and the second connecting end 1131 is greater than 45°, the angle is too large, resulting in a channel with a large bending angle between the second channel 113 and the connecting cavity 114. When the airflow enters the channel, it is easy to hit the inner wall of the connecting cavity 114 and the second channel 113, resulting in energy loss and thus affecting the dust suction efficiency.

[0055] Therefore, in this embodiment of the invention, the included angle between the first connecting end 1121 and the second connecting end 1131 is set to be greater than or equal to 15° and less than or equal to 45°. For example, it can be 15°, 20°, 25°, 30°, 35°, 40°, or 45°. By controlling the included angle between the first connecting end 1121 and the second connecting end 1131 within a suitable range, the second channel 113 is easily connected to an external suction device, while the kinetic energy loss of the airflow entering the second channel 113 through the connecting cavity 114 is minimized, thereby ensuring a faster airflow speed and improving the efficiency of dust removal.

[0056] In one embodiment, the area of ​​the working port 111 is less than or equal to the area of ​​the outlet of the second channel 113. When the airflow passes through the smaller working port 111, the airflow velocity is faster, thereby more effectively entraining the dust generated by laser cleaning and drawing the dust into the second channel 113, reducing the probability of dust escape.

[0057] Furthermore, since the working port 111 is also the laser outlet, the length of the working port 111 usually needs to be greater than the width of the laser to ensure that the laser can play a better role. Therefore, in this embodiment of the utility model, the working port 111 can be set as a rectangle. The regular shape is easy to process, and the length of the rectangle is relatively long, which can better meet the requirements of the laser emitting device.

[0058] In one embodiment, reference is made to Figure 3 and Figure 4 The dust cover 1 also includes a light-transmitting element 12, which is disposed in the first channel 112 for allowing laser light to pass through.

[0059] By incorporating a light-transmitting element 12 within the first channel 112, the laser can smoothly pass through the first channel 112 to clean the battery, while the light-transmitting element 12 prevents dust from flowing through the first channel 112 to the laser emitting device, reducing the probability of dust contamination of the laser emitting device. The light-transmitting element 12 can be made of materials such as quartz glass, borosilicate glass, crystal, polycarbonate, or acrylic sheet, possessing good transparency and high material strength.

[0060] In one embodiment, the thickness of the light-transmitting element 12 is greater than or equal to 2 mm and less than or equal to 3 mm.

[0061] If the thickness of the light-transmitting element 12 is less than 2mm, the strength of the light-transmitting element 12 is too low. It may be damaged during the manufacturing, transportation or installation of the dust cover 1, resulting in a decrease in the sealing or light transmission of the light-transmitting element 12, which in turn affects the efficiency of laser cleaning. If the thickness of the light-transmitting element 12 is greater than 3mm, the thickness of the light-transmitting element 12 is too large. At the same time, the manufacturing cost increases, and the weight of the dust cover 1 also increases accordingly, affecting the installation of the dust cover 1.

[0062] Therefore, in this embodiment of the invention, the thickness of the transparent component is set to be greater than or equal to 2mm and less than or equal to 3mm. For example, it can be 2mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, 2.6mm, 2.7mm, 2.8mm, 2.9mm, 3mm, etc. By controlling the thickness of the transparent adhesive within a suitable range, the transparent component achieves good mechanical strength while maintaining a low weight, thereby reducing the installation difficulty of the dust cover 1.

[0063] In the laser dust removal equipment provided in related technologies, the dust cover often needs to be placed on the battery, which results in a limited range of applicability of the dust cover. Different dust covers are required for different types of batteries, leading to high battery cleaning costs.

[0064] Based on this, and according to the second aspect of the present invention, referring to Figure 5 A laser dust removal device 3 is provided, including a laser 31 and a dust cover 1 as described in the previous embodiment. The working port 111 of the dust cover 1 is positioned facing the battery. The laser 31 is positioned corresponding to the entrance of the first channel 112 for emitting laser light to the battery. Since the laser dust removal device 3 includes the aforementioned dust cover 1, it possesses all the beneficial effects of the aforementioned dust cover 1. Further details of this embodiment will not be elaborated upon here.

[0065] The dust cover 1 can be installed on the side of the battery without directly interfering with it, making it adaptable to various types of batteries and allowing for battery cleaning without affecting the battery's rotation or movement. The laser 31 can be a solid-state laser, a gas laser, or a semiconductor laser; this invention does not impose any limitations on this.

[0066] In one embodiment, reference is made to Figure 5 The laser dust removal device 3 also includes a mounting base 32, a dust cover 1, and at least one of a laser 31 connected to the mounting base 32.

[0067] The mounting base 32 provides stable support for at least one of the dust cover 1 and the laser 31. When the laser 31 is connected to the mounting base 32, the mounting base 32 significantly improves the stability of the laser 31, thereby ensuring the efficiency of laser cleaning. When the dust cover 1 is connected to the mounting base 32, the mounting base 32 improves the stability of the dust cover 1 and reduces the vibration that may occur when suctioning dust.

[0068] Understandably, there are various ways to connect the dust cover 1 or the laser 31 to the mounting base 32, and designers can make reasonable designs according to actual needs. For example, when the dust cover 1 and the mounting base 32 are detachable, the dust cover 1 can be fixedly connected to the mounting base 32 by at least one of the following methods: screw connection, snap-fit ​​connection, or plug-in connection; or, for example, when the dust cover 1 and the mounting base 32 are non-detachable, the dust cover 1 can be fixedly connected to the mounting base 32 by welding or bonding.

[0069] In some alternative embodiments, the mounting base 32 serves as a common fixing platform for the dust cover 1 and the laser 31, simplifying the installation operation of the dust cover 1 and the laser 31, while eliminating the relative position error caused by the independent installation of the dust cover 1 and the laser 31, ensuring that the laser beam always passes accurately through the first channel 112 of the dust cover 1.

[0070] In one embodiment, reference is made to Figure 5 The laser dust removal equipment 3 also includes a moving device 33, which is connected to the mounting base 32 for adjusting the position of the mounting base 32.

[0071] By connecting the moving device 33 to the mounting base 32, the operator can dynamically adjust the position of the mounting base 32 by controlling the moving device 33, thereby adjusting the position of the dust cover 1 and the laser 31, which significantly improves the process adaptability and operating efficiency of the laser dust removal equipment 3.

[0072] The moving device 33 can be a cylinder, lead screw, or robotic arm. If the laser 31 is connected to the mounting base 32, the moving device 33 can drive the mounting base 32 to move the laser 31, thereby precisely cleaning various locations on the battery surface (such as the battery curved surface or weld seam) and improving the cleaning efficiency of the laser dust removal equipment 3. If the dust cover 1 is connected to the mounting base 32, the moving device 33 can drive the mounting base 32 to move the dust cover 1, adjusting the alignment of the first channel 112 in the dust cover 1 with the laser 31 to ensure that the laser can irradiate the battery. It can also improve the probability of dust being captured by real-time matching of the relative position of the laser focus and the working port 111.

[0073] In some optional embodiments, the laser dust removal device 3 also includes a processing station for holding the battery. When the laser 31 cleans the battery, the distance between the processing station and the working port 111 is greater than or equal to 4 mm and less than or equal to 8 mm.

[0074] If the distance between the processing position and the working port 111 is less than 4mm, the battery is too close to the working port 111, which can easily clog the working port 111, resulting in insufficient airflow and reduced dust removal efficiency. If the distance between the processing position and the working port 111 is greater than 8mm, the battery is too far from the working port 111, making it difficult for the airflow generated at the working port 111 to reach the battery surface, thus affecting the dust removal effect. Therefore, the distance between the processing position and the working port 111 is set to be greater than or equal to 4mm and less than or equal to 8mm. For example, it can be 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, or 8mm, so that the distance between the processing position and the working port 111 is maintained within a suitable range, and the external suction equipment can achieve a better dust removal effect through the dust cover 1.

[0075] In one embodiment, reference is made to Figure 5 The laser dust removal device 3 also includes a nitrogen supply component 34, which is connected to the mounting base 32 and is used to supply nitrogen to the battery.

[0076] By setting up a nitrogen supply component 34 and blowing nitrogen gas onto the battery, the heat generated during laser cleaning of the battery surface is removed, while the laser output power and beam quality are improved, thereby increasing the cleaning efficiency of the battery.

[0077] The embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
