[0019] 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.

[0020] like Figure 1 and Figure 2 As shown, the battery pole laser cleaning device 100 of the present invention includes a positioning and clamping device 10, an X-axis conveying module 20 and a laser cleaning head 30. The positioning and clamping device 10 includes a clamping module 11 and a side positioning module 12 for side positioning of the battery. The side positioning module 12 is arranged above the clamping module 11. The side positioning module 12 performs side positioning of the battery. The side positioning module 12 can be raised and lowered. After the side positioning module 12 performs side positioning of the battery, it descends to place the battery into the clamping module 11. The clamping module 11 clamps the placed battery. The clamping module 11 is installed at the output end of the X-axis conveying module 20. The laser cleaning head 30 is arranged above the clamping module 11. The X-axis conveying module 20 is used to drive the clamping module 11 to slide along the X-axis so that the clamping module 11 moves in or out from directly below the laser cleaning head 30.

[0021] During cleaning, the battery is loaded into the side positioning module 12, and the side positioning module 12 positions the battery laterally. The side positioning module 12 then descends and places the laterally positioned battery into the clamping module 11, which clamps the placed battery. After the battery is laterally positioned, the position of the pole is determined. By clamping the battery with the clamping module 11, the battery pole can be kept in the processing position. The X-axis conveying module 20 drives the clamping module 11 to slide along the X-axis, so that the clamping module 11 moves directly under the laser cleaning head 30. The laser cleaning head 30 cleans the pole and uses the pulse energy of the laser to remove the ink layer and oxide layer on the surface of the pole, which is beneficial for subsequent battery module welding. Afterwards, the X-axis conveying module 20 drives the clamping module 11 to slide along the X-axis, so that the clamping module 11 moves directly under the laser cleaning head 30, completing the cleaning process of the pole.

[0022] Before cleaning, the battery is first positioned using the side positioning module 12, and then clamped using the clamping module 11, thereby ensuring the accuracy and reliability of the cleaning of the terminal. Furthermore, the battery terminal laser cleaning device 100 of the present invention uses an automated cleaning method, which can continuously laser clean the terminals of multiple batteries, effectively improving cleaning efficiency. There is no physical contact with the terminals during the entire cleaning process, which significantly improves cleaning quality and efficiency compared to traditional cleaning methods.

[0023] It is worth noting that the battery type is not specifically limited and can be lithium-ion power batteries, energy storage batteries, etc. in the new energy industry, and can be in the form of square aluminum shell batteries and cylindrical batteries, etc. The laser cleaning head 30 is composed of a laser generator, a galvanometer, and a field mirror, etc., which are used for laser emission, control of the direction and position of the light beam, and focusing and divergence of the light beam, respectively, to complete the laser cleaning process. In addition, a chiller is provided to cool the laser cleaning head 30 to prevent the laser cleaning head 30 from overheating. The laser cleaning performance is stable, the uniformity and consistency of the cleaned surface are good, and the laser has a certain degree of controllability. By adjusting the laser parameters and the amount of auxiliary gas to obtain the desired roughening morphology and roughness, the subsequent battery module welding performance can be improved.

[0024] like Figure 1 and Figure 2 As shown, the side positioning module 12 includes a side pushing driver 121, a side pushing block 122, and a side positioning block 123. The side pushing block 122 and the side positioning block 123 are spaced apart along the Y-axis. The side pushing block 122 is mounted at the output end of the side pushing driver 121. The side pushing driver 121 drives the side pushing block 122 to translate along the Y-axis toward or away from the side positioning block 123. After the battery is inserted, the side pushing driver 121 drives the side pushing block 122 to translate toward the side positioning block 123 to position the battery.

[0025] like Figure 1 and Figure 2As shown, the battery pole laser cleaning equipment 100 of the present invention also includes a support plate 40 and a lifting drive 50. The side positioning module 12 is installed on the top of the support plate 40, and the support plate 40 is installed on the output end of the lifting drive 50. The lifting drive 50 drives the support plate 40 to move up and down. After the lifting drive 50 drives the support plate 40 to move downward, the side positioning module 12 places the positioned battery into the clamping module 11. In order to better position the battery, the side positioning module 12 also includes a supporting member 124 installed on the top of the support plate 40. The supporting member 124 is provided with a positioning groove 1241 for inserting the battery. Inserting the battery into the positioning groove 1241 can improve the accuracy of positioning the battery.

The clamping positioning block 112 is arranged on one side of the support base 111 along the X-axis direction, and the clamping pushing block 113 and the clamping positioning block 112 are spaced apart along the X-axis direction. The clamping pushing block 113 is installed with the output end of the clamping driver 114, and the clamping driver 114 drives the clamping pushing block 113 to move closer to or away from the clamping positioning block 112. The clamping driver 114 drives the clamping pushing block 113 to move closer to or away from the clamping positioning block 112, and the clamping pushing block 113 and the clamping positioning block 112 clamp the placed battery together. Preferably, the clamping driver 114 is a cylinder, but is not limited to this. The clamping module 11 is compatible with a variety of batteries, such as square aluminum shell batteries, etc., and can clean different types of battery poles. Preferably, the clamping and pushing block 113 and the clamping and positioning block 112 can be set to a floating form, for example, using an elastic structure, so that the clamping module 11 can better clamp the battery.

[0027] like Figure 1 and Figure 2 As shown, the positioning and clamping device 10 includes multiple groups of clamping modules 11 arranged along the X-axis direction and multiple groups of side positioning modules 12 arranged along the X-axis. After the side positioning modules 12 are loaded with multiple batteries, four batteries can be laterally positioned at the same time and then the four batteries can be clamped, thereby improving processing efficiency.

[0028] In the embodiment provided by the present invention, a total of four sets of clamping modules 11 and four sets of side positioning modules 12 are provided. The X-axis conveyor module 20 can first drive two clamping modules 11 to be directly under the laser cleaning head 30 to clean the two battery terminals. Then, the X-axis conveyor module 20 drives another two clamping modules 11 to be directly under the laser cleaning head 30 to clean the remaining two battery terminals. Of course, other feeding methods can also be used according to actual production needs.

The second end of the branch pipe 72 is connected to the main pipe 71. The main pipe 71 is connected to the explosion-proof dust removal fan. The main pipe 71 generates negative pressure through the explosion-proof dust removal fan. The dust generated during the cleaning process is sucked into the pipe head 73, then flows through the branch pipe 72, and then gathers into the main pipe 71 and flows out and is collected by the explosion-proof dust removal fan.

[0031] A support frame 80 is provided below the laser cleaning head 30. The support frame 80 spans the X-axis conveying module 20.
