[0045] In the description of the present application, it should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments of the present application. For the convenience of description, the dimensions of each part shown in the drawings are not drawn according to the actual proportional relationship.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0046] Embodiment 1:

[0047] This embodiment provides an integrated device for weld cleaning, detection, and milling, including: an execution device 1 and a moving device for driving the execution device 1 to move along a first direction X and a second direction Y;

[0048] The execution device 1 includes:

[0049] A fixing frame 11, and the fixing frame 11 is installed on the moving end of the moving device;

[0050] A cleaning and dust removal mechanism 12 for cleaning the weld;

[0051] A first lifting mechanism 13 installed on the fixing frame 11 and used to drive the cleaning and dust removal mechanism 12 to move along a third direction Z;

[0052] A detection and milling mechanism 14, which includes a base, a height detection module for detecting the height of the weld, an offset detection module 141 for detecting the offset angle of the weld, and a milling module for milling the weld with welding defects. The height detection module, the offset detection module 141, and the milling module are all installed on the base;

[0053] A second lifting mechanism 15 installed on the fixing frame 11 and used to drive the base to move along a third direction Z.

[0054] In this technical solution, after the battery module and the battery PACK structure are welded and assembled, the mobile device drives the fixing frame 11 of the actuating device 1 to move along the first direction X and the second direction Y, so that the cleaning and dust removal mechanism 12 is located above the weld of the battery module or the battery PACK structure. Then, the first lifting mechanism 13 controls the cleaning and dust removal mechanism 12 to descend along the third direction Z. The first lifting mechanism 13 can be a lead screw drive module. The cleaning and dust removal mechanism 12 cleans the weld to prevent the welding slag generated by the welding process from staying at the weld and affecting the subsequent detection work. After the cleaning is completed, the first lifting mechanism 13 controls the cleaning and dust removal mechanism 12 to rise and reset along the third direction Z.

[0055] After the weld is cleaned, the mobile device drives the fixing frame 11 to move and adjust, so that the detection and milling mechanism 14 is located above the weld. The second lifting mechanism 15 controls the base of the detection and milling mechanism 14 to descend along the third direction Z. The second lifting mechanism 15 can also be a lead screw drive module. The height detection module and the offset detection module 141 on the base scan and detect the cleaned weld. If a weld bead is detected due to excessive weld height or weld offset, the milling module is used to mill and remove the weld bead. Then, the second lifting mechanism 15 controls the detection and milling mechanism 14 to rise and reset along the third direction Z. The removed weld bead can be removed by the cleaning and dust removal mechanism 12. Through this structural design, it is ensured that the weld is flat, which helps with subsequent processing and assembly, and also avoids local stress concentration and ensures the welding strength.

[0056] In summary, the cleaning and dust removal mechanism 12 can clean the welding slag generated by the welding process at the weld, eliminating the need for workers to clean the weld and improving the cleaning efficiency. The height detection module and the offset detection module 141 can detect the height and offset angle of the weld, and then the milling module is used to mill and remove the weld bead, eliminating the need for manual trimming of the weld bead. This effectively reduces the manual input in the production process, improves the degree of production automation, and thus effectively improves production efficiency and production safety.

[0063] Furthermore, the spacing adjustment module 142 is a lead screw module, and the vision detection unit 143 is a 3D camera.

[0064] In this technical solution, the spacing adjustment module 142 can be a lead screw module. The rotating lead screw in the lead screw module can be a bi-directional screw. The two vision detection units 143 are respectively threadedly connected and installed on the two threaded sections of the bi-directional screw. By rotating the lead screw forward or backward, the two vision detection units 143 are driven to approach or move away from each other, realizing the adjustment of the distance between the two vision detection units 143, so as to adapt to the situation where the pole column spacings of different products are inconsistent.

[0079] A dust removal unit, which is installed on the base frame and is used for cleaning the weld seam;

[0080] A dust suction unit, which is installed on the base frame and is used for sucking the dust generated during the cleaning process.

[0081] In this technical solution, the first lifting mechanism 13 controls the base frame to move along the third direction Z, drives the dust removal unit to approach the weld seam to clean the weld seam, removes the welding slag generated by welding, and at the same time, the dust suction unit will suck the welding slag and the dust generated during the cleaning process to achieve the cleaning work of the weld seam.

[0082] Embodiment 6:

[0087] A driving member 123, which is installed on the base frame and is used for driving the dust removal brush 122 to rotate.

[0088] In this technical solution, the driving member 123 can be a motor. One end of the dust removal brush 122 is connected to the motor, and the other end is rotatably connected to the base frame. The bristles of the dust removal brush 122 are located in the dust removal chamber 121. By driving the dust removal brush 122 to rotate through the motor, the bristles will clean the welding slag at the weld seam, eliminating the need for manual cleaning and having high practicality.

In addition, the anemometer 125 can monitor the wind speed in the dust suction pipe 124, which can not only prevent the wind speed in the dust suction pipe 124 from being too small to completely suck out the welding slag and dust, but also prevent the wind speed in the dust suction pipe 124 from being too large, resulting in energy waste.
