[0002] During the production and assembly of battery modules, inkjet printing is required on the cell surface. Prior to inkjet printing, the cell surface must be cleaned to ensure the quality and efficiency of subsequent inkjet printing. Currently, related equipment uses laser energy to create a micro-textured structure on the surface of the battery casing. This creates a roughened surface, imparting a certain degree of roughness and surface energy, which facilitates stronger adhesion during the subsequent inkjet printing process.

[0003] However, to clean multiple battery cell surfaces, the current method still relies on manual flipping of the battery casing, allowing the cleaning device to clean different sides of the battery casing. However, processing different sides of the battery requires repositioning the battery, and there is only one type of positioning fixture. This operation is time-consuming and cumbersome. Furthermore, the dust generated during cleaning is not collected and scatters everywhere, polluting the work environment.

[0022] In order to explain the technical content and structural features of the present invention in detail, the following is a further description in conjunction with the embodiments and the accompanying drawings.

[0023] like Figure 1 and Figure 2 As shown, the utility model discloses a battery casing surface laser cleaning device 100, which is used for laser cleaning the battery casing, using laser energy to form a micro-texture structure on the surface of the battery casing, so that the surface of the battery casing achieves a roughening effect, with a certain roughness and surface energy, so that the battery casing has stronger adhesion in the subsequent inkjet printing process.

[0024] The battery casing surface laser cleaning device 100 of the present invention includes a laser cleaning head 10, an X-axis conveying module 20, and multiple positioning jigs. The positioning jig is mounted at the output end of the X-axis conveying module 20, and the laser cleaning head 10 is positioned above the positioning jig. The X-axis conveying module 20 is used to drive the positioning jig to slide along the X-axis, so that the positioning jig moves in or out directly below the laser cleaning head 10. The multiple positioning jigs have different orientations, and after the multiple positioning jigs have positioned the battery casing, the side surfaces of each battery casing exposed upward are different.

[0025] When performing the cleaning operation, first install the battery shell into one of the positioning jigs, which positions the battery shell. The X-axis conveying module 20 drives the positioning jig to slide along the X-axis, so that the positioning jig after positioning the battery moves directly under the laser cleaning head 10. The laser cleaning head 10 cleans the side of the battery shell exposed upward, and uses laser energy to form a micro-texture structure on the surface of the battery shell exposed upward, so that the surface of the battery shell exposed upward achieves a roughening effect, with a certain roughness and surface energy, which facilitates the battery shell to have stronger adhesion in the subsequent inkjet printing process. Similarly, the batteries are successively loaded into other positioning jigs, and the same processing actions are performed until the laser cleaning process of all sides of the battery shell is completed.

[0026] After positioning the battery casing, each battery casing mounted in each positioning fixture has a different side surface exposed upward. For example, one battery casing may have its front side exposed upward, one may have its left side exposed upward, and one may have its top side exposed upward. These are merely examples of some of the states of the battery casing after positioning and do not constitute a specific limitation on how the battery casing is positioned.

[0027] After the battery casing is positioned using multiple positioning jigs, the upwardly exposed side surfaces of each battery casing are different. After the battery casing is successively loaded into different positioning jigs, the laser cleaning head 10 can laser clean different sides of the battery casing. When laser cleaning different sides of the battery casing, it is only necessary to load the battery casing into the corresponding battery jig, which simplifies the positioning of the battery casing and shortens the time spent on positioning the battery casing, thereby allowing for efficient cleaning of the sides of the battery casing.

[0028] Laser has a certain degree of controllability. The laser parameters and the amount of auxiliary gas can be adjusted to obtain the desired texturing morphology and roughness, which can make the subsequent UV inkjet surface more beautiful.

[0029] It is worth noting that the battery type is not limited and can include lithium-ion power batteries and energy storage batteries from the new energy industry, and can be shaped like square aluminum batteries or cylindrical batteries. The laser cleaning head 10 is composed of a laser generator, a galvanometer, and a field lens, which are used for laser emission, beam direction and position control, and beam focusing and divergence, respectively, to complete the laser cleaning process. A chiller is also provided to cool the laser cleaning head 10 to prevent overheating.

[0030] like Figures 1 to 4 As shown, multiple positioning jigs are arranged adjacent to each other. Multiple positioning jigs include at least a first positioning jig 30, a second positioning jig 40 and a third positioning jig 50. The first positioning jig 30 and the second positioning jig 40 are arranged adjacent to each other along the X-axis direction. The third positioning jig 50 is provided on one side of the first positioning jig 30 and the second positioning jig 40, and the third positioning jig 50 is arranged adjacent to the first positioning jig 30 and the second positioning jig 40 along the Y-axis direction. The first positioning jig 30, the second positioning jig 40 and the third positioning jig 50 can be used to position the six sides of the battery casing, and the six exposed sides of the battery casing can be cleaned and processed in turn. It can be understood that a larger number of positioning jigs can be selected, and it is not limited to three positioning jigs.

The first push member 33 can be translated along the Y-axis direction to approach or move away from the first end face stopper 32, and the first push member 33 and the first end face stopper 32 jointly clamp the battery shell. The first support seat 31 provides support for the battery shell, and after the first push member 33 is translated close to the first end face stopper 32, the positioning of the battery shell is achieved, and the battery shell is stably exposed with one side upward.

[0032] Preferably, the first push member 33 is driven by a cylinder to translate along the Y-axis, but the present invention is not limited thereto. Furthermore, the first positioning fixture 30 further includes a first side stopper 34, which is disposed on one side of the first end surface stopper 32 along the X-axis. The provision of the first side stopper 34 can enhance the positioning of the battery housing, making the positioning of the battery housing more stable and reliable.

[0033] like Figures 1 to 4As shown, the second positioning fixture 40 includes a second end face stopper 41, a second push member 42 and a second side stopper 43. The second end face stopper 41 and the second push member 42 are arranged alternately along the Y-axis direction. The second push member 42 can be translated along the Y-axis towards or away from the second end face stopper 41. The second push member 42 and the second end face stopper 41 jointly clamp the battery shell. The second side stopper 43 is arranged on one side of the second end face stopper 41 along the X-axis direction. After the second push member 42 is translated close to the second end face stopper 41, the positioning of the battery shell is achieved, and the battery shell stably exposes one side upward. Preferably, the second push member 42 is driven by a cylinder to translate along the Y-axis direction, but is not limited to this. The second side stopper 43 can be used to strengthen the positioning of the battery shell, making the positioning of the battery shell more stable and reliable.

[0034] To optimize the structural layout, such as Figure 3 and Figure 4 As shown, the first end surface stopper 32 and the second end surface stopper 41 are respectively installed on the same side plate 01.

[0035] like Figures 1 to 4 As shown, the third positioning fixture 50 includes a second support base 51, a third side stop 52, a fourth side stop 53, a fifth side stop 54, and a third push member 55. The second support base 51 is located below the third, fourth, and fifth side stops 52, 53, 54. The third and fourth side stops 52, 53 are arranged alternately along the Y-axis. The fifth side stop 54 is located on one side of the third and fourth side stops 52, 53 along the X-axis. The third push member 55 is located on the other side of the third and fourth side stops 52, 53 along the X-axis. The third push member 55 can translate along the X-axis toward or away from the fifth side stop 54. The third push member 55 and the fifth side stop 54 jointly clamp the battery housing. The second support base 51 provides support for the battery housing, while the third and fourth side stops 52, 53 limit the sides of the battery housing. After the third pushing member 55 moves horizontally toward the fifth side stopper 54 , the battery housing is positioned, and the battery housing stably exposes one side surface upward.

[0036] like Figure 1 、 Figure 2 and Figure 5As shown, the battery shell surface laser cleaning equipment 100 of the present invention also includes a Y-axis conveying module 60 and a Z-axis conveying module 70. The Z-axis conveying module 70 is installed at the output end of the Y-axis conveying module 60, and the Y-axis conveying module 60 drives the Z-axis conveying module 70 to translate in the Y-axis direction. The laser cleaning head 10 is installed at the output end of the Z-axis conveying module 70, and the Z-axis conveying module 70 drives the laser cleaning head 10 to translate in the Z-axis direction. By driving the laser cleaning head 10 to slide in the Y-axis and Z-axis directions through the Y-axis conveying module 60 and the Z-axis conveying module 70, and cooperating with the X-axis conveying module 20 to drive the sliding of the positioning fixture, the laser cleaning head 10 can clean the side of the battery shell in the three-dimensional directions of the X-axis, Y-axis and Z-axis, so as to better perform the cleaning operation. The X-axis conveying module 20, the Y-axis conveying module 60 and the Z-axis conveying module 70 can adopt the existing structure, which will not be repeated here.

[0037] like Figure 1 、 Figure 2 and Figure 5 As shown, in order to prevent the dust generated by cleaning from flying around, the battery shell surface laser cleaning equipment 100 of the present invention also includes a dust suction device 80, which is used to remove the dust generated by cleaning. In order to facilitate the installation of the dust suction device 80, the battery shell surface laser cleaning equipment 100 of the present invention also includes a fixed bracket 90. The fixed bracket 90 is installed at the output end of the Z-axis conveying module 70, and the fixed bracket 90 surrounds the outer side of the laser cleaning head 10.
