Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0043] Please see Figure 1 and Figure 2The laser cleaning apparatus provided in this application embodiment will now be described. The laser cleaning apparatus provided in this application embodiment is used to perform laser cleaning on the cleaning area of ​​a workpiece 100, the workpiece 100 including multiple cleaning areas arranged sequentially along a first direction. It can be understood that the workpiece 100 can be a battery cell module to be placed in a box. The battery cell module includes multiple rows of battery cell groups arranged sequentially along the first direction, and each row of battery cell groups includes multiple columns of individual battery cells arranged sequentially along a second direction. That is, the individual battery cells are arranged sequentially along both the first and second directions. The position requiring cleaning in each row of battery cell groups is designated as a cleaning area. Of course, the workpiece 100 can also be other workpieces 100 that require laser cleaning.

[0044] The laser cleaning apparatus provided in this application includes a first moving module 10, a second moving module 20, a third moving module 30, a visual positioning mechanism 40, and a laser cleaning head 50.

[0045] The second moving module 20 and the third moving module 30 are disposed at intervals on the first moving module 10 along the first direction, and the first moving module 10 drives the second moving module 20 and the third moving module 30 to move along the first direction.

[0046] like Figure 3 As shown, the visual positioning mechanism 40 is mounted on the second moving module 20. The second moving module 20 drives the visual positioning mechanism 40 to move along a second direction to position a cleaning area. Driven by the second moving module 20, the visual positioning mechanism 40 can move along the second direction, thereby positioning a cleaning area of ​​the workpiece 100.

[0047] like Figure 2 As shown, the laser cleaning head 50 is mounted on the third moving module 30. The third moving module 30 drives the laser cleaning head 50 to move along the second direction to perform laser cleaning on the cleaning area positioned by the vision positioning mechanism 40. Since the cleaning range of the laser cleaning head 50 is limited, cleaning of one cleaning area can be achieved when the third moving module 30 drives the laser cleaning head 50 to move along the second direction.

[0048] The first and second directions are set at an angle, for example, 90°, 45°, 150°, or any other angle. Please refer to [link / reference]. Figure 1 The "first direction" can be represented by the Y-axis, and the "second direction" can be represented by the X-axis. The "third direction" described below can be represented by the Z-axis.

[0049] The cleaning process of the laser cleaning apparatus in this embodiment is as follows:

[0050] First, the first moving module 10 drives the second moving module 20 and the third moving module 30 to move synchronously along the first direction until the visual positioning mechanism 40 is directly aligned with the first cleaning area of ​​the workpiece 100.

[0051] Next, the second moving module 20 drives the visual positioning mechanism 40 to move along the second direction to position the first cleaning area. When the visual positioning mechanism 40 has finished positioning the first cleaning area, the second moving module 20 stops driving.

[0052] Then, the first moving module 10 drives the second moving module 20 and the third moving module 30 to move synchronously along the first direction until the visual positioning mechanism 40 is directly opposite the second cleaning area of ​​the workpiece 100. At this time, the laser cleaning head 50 is directly opposite the first cleaning area, and the first moving module 10 stops driving.

[0053] Finally, the second moving module 20 drives the visual positioning mechanism 40 to move along the second direction to position the second cleaning area, while the third moving module 30 drives the laser cleaning head 50 to move along the second direction to perform laser cleaning on the first cleaning area.

[0054] After the vision positioning mechanism 40 completes the positioning of the second cleaning area and the laser cleaning head 50 completes the laser cleaning of the first cleaning area, the first moving module 10 continues to drive the second moving module 20 and the third moving module 30 to move synchronously along the first direction until the vision positioning mechanism 40 is directly opposite the third cleaning area of ​​the workpiece 100. At this time, the laser cleaning head 50 is directly opposite the second cleaning area. The above steps are repeated until the cleaning of all cleaning areas is completed.

[0055] The laser cleaning apparatus provided in this application embodiment, by setting the visual positioning mechanism 40 on the second moving module 20 and the laser cleaning head 50 on the third moving module 30, allows for the positioning and cleaning of a cleaning area of ​​the workpiece 100 when necessary. The second moving module 20 drives the visual positioning mechanism 40 to move along a second direction to position a cleaning area, while the third moving module 30 drives the laser cleaning head 50 to move along the second direction to perform laser cleaning on the positioned area. After the positioning and laser cleaning of one cleaning area are completed, since the second moving module 20 and the third moving module 30 are spaced apart on the first moving module 10 along a first direction, the first moving module 10 can drive the second moving module 20 and the third moving module 30 to move synchronously along the first direction to position and perform laser cleaning on the next cleaning area. Using the laser cleaning apparatus of this application embodiment allows the visual positioning mechanism 40 and the laser cleaning head 50 to perform visual positioning and laser cleaning simultaneously, improving cleaning efficiency and saving time and costs.

[0056] Please see Figure 3 and Figure 4 The visual positioning mechanism 40 may include a fourth moving module 41 and an image-taking component 42. The fourth moving module 41 is mounted on the second moving module 20. The image-taking component 42 is mounted on the fourth moving module 41, and the fourth moving module 41 drives the image-taking component 42 to move along a first direction to adjust the distance between the image-taking component 42 and the laser cleaning head 50. Since the spacing between the cleaning areas of different workpieces 100 along the first direction is different, by adjusting the distance between the image-taking component 42 and the laser cleaning head 50, it is possible to ensure that when the laser cleaning head 50 is in the current cleaning area, the image-taking component 42 is located in the next or several interval cleaning area. This allows for simultaneous laser cleaning of the current cleaning area and simultaneous visual positioning of the next or several interval cleaning areas, resulting in higher compatibility.

[0057] Please see Figure 3 and Figure 4 The visual positioning mechanism 40 may further include a fifth moving module 43. The fifth moving module 43 is mounted on the second moving module 20, and a fourth moving module 41 is mounted on the fifth moving module 43. The second moving module 20 drives the fifth moving module 43 to move along a second direction, and the fifth moving module 43 drives the fourth moving module 41 to move along a third direction to approach or move away from the cleaning area of ​​the workpiece 100. By configuring the fifth moving module 43, the distance between the imaging component 42 and the cleaning area of ​​the workpiece 100 can be adjusted, thus making it suitable for workpieces 100 of different heights.

[0058] The third direction is set at an angle to the first and second directions. For example, the third direction can be at 90° to the first and second directions, or it can be at any other angle such as 45° or 150°.

[0059] Please see Figure 4 The visual positioning mechanism 40 may further include a height gauge 44, mounted on the fourth moving module 41, for measuring the height of the cleaning area of ​​the workpiece 100. By setting the height gauge 44, the height of the cleaning area of ​​the workpiece 100 can be measured, thereby providing a height reference for the laser cleaning head 50, thus achieving precise cleaning. Specifically, the height gauge 44 can be a 3D profilometer.

[0060] Please see Figure 4 The visual positioning mechanism 40 may also include a light source assembly 45, which is disposed on the fourth moving module 41 and located below the photographing assembly 42. The light source assembly 45 provides illumination to the photographing assembly 42.

[0061] Please see Figure 1 and Figure 2The laser cleaning head 50 may include at least two, with each laser cleaning head 50 spaced apart along the second direction. By setting at least two laser cleaning heads 50, when laser cleaning of the cleaning area is required, each laser cleaning head 50 can work simultaneously, further improving cleaning efficiency. Specifically, in one embodiment of this application, two laser cleaning heads 50 are set. When one laser cleaning head 50 is facing one side of the cleaning area along the second direction, the other laser cleaning head 50 is facing the middle of the cleaning area along the second direction. During laser cleaning, the two laser cleaning heads 50 move synchronously along the second direction. When one laser cleaning head 50 is exactly at the middle of the cleaning area along the second direction, the other laser cleaning head 50 is exactly at the other side of the cleaning area along the second direction, thereby achieving complete cleaning of the cleaning area and improving cleaning efficiency. Of course, the laser cleaning heads 50 can also be set according to actual needs, for example, there can be three or more.

[0062] Please see Figure 5 The laser cleaning head 50 may include a sixth moving module 51 and a galvanometer assembly 52. ​​The sixth moving module 51 is disposed on the third moving module 30, and the third moving module 30 drives the sixth moving module 51 to move along a second direction. The galvanometer assembly 52 is disposed on the sixth moving module 51, and the sixth moving module 51 drives the galvanometer assembly 52 to move along a third direction to adjust the distance between the galvanometer assembly 52 and the cleaning area of ​​the workpiece 100, thereby achieving precise cleaning of the workpiece 100.

[0063] Please see Figure 5 The laser cleaning head 50 may also include a dust extraction component 53, which is mounted on the sixth moving module 51, for removing dust generated during the laser cleaning process. The dust extraction component 53 prevents dust from contaminating the workpiece 100.

[0064] Please see Figure 5 The laser cleaning head 50 may also include an air knife 54, which is mounted on the sixth moving module 51 and is used to blow air to prevent dust generated during the laser cleaning process from contaminating the galvanometer assembly 52. ​​The air knife 54 improves the cleanliness of the galvanometer assembly 52.

[0065] Please see Figure 1 and Figure 2 The laser cleaning device may also include a frame 60 and a crossbeam 70. A first moving module 10 is disposed on the frame 60, and the crossbeam 70 is disposed on the first moving module 10 and driven by the first moving module 10 to move along a first direction. A second moving module 20 and a third moving module 30 are respectively disposed at intervals on the crossbeam 70 along the first direction, so that the overall structure is simple and compact, which is conducive to reducing the volume.

[0066] Please see Figure 1The laser cleaning device may also include an AGV trolley 80, which is used to carry a tray containing a workpiece 100. Through the movement of the AGV trolley 80, the workpiece 100 is automatically fed, reducing labor costs.

[0067] Please see Figure 1 The first moving module 10, the second moving module 20, the third moving module 30, the fourth moving module 41, the fifth moving module 43 and the sixth moving module 51 can be driven by linear cylinders or linear motors, or they can be driven by rotary motors and equipped with a transmission mechanism that can convert the rotational driving force of the rotary motor into linear motion, such as gear rack or lead screw.

[0068] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
