The terminology used in the description of the disclosure herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0040] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below in combination with specific embodiments:

[0041] Please refer to Figure 1 With Figure 2The battery pack busbar milling device of one embodiment comprises a rack, a milling platform 200, a traveling support 300, a 2D camera module 400, a 3D camera module 500, a milling assembly 600, an image processing system (not shown in the figure) and a numerical control system (not shown in the figure); the milling platform 200 is arranged in the rack, and the milling platform 200 is used for placing the battery pack 10; the 2D camera module 400 is installed on the rack and located above the milling platform 200; the lens of the 2D camera module 400 faces upward above the milling platform 200; the 2D camera module 400 is used for collecting the planar profile image of the top of the battery pack 10; the traveling support 300 is arranged above the milling platform 200 and is slidingly arranged on the rack; the 3D camera module 500 and the milling assembly 600 are both slidingly installed on the traveling support 300, and the lens of the 3D camera module 500 faces upward above the milling platform 200; the 3D camera module 500 is used for collecting the stereoscopic profile image of the top of the battery pack 10; the image processing system is used for matching the planar profile image and the stereoscopic profile image to obtain the busbar coordinates; the numerical control system is used for generating the busbar milling path according to the busbar coordinates to drive the milling assembly 600 to mill the busbar 20 on the battery pack 10 according to the busbar milling path.

[0042] It can be understood that, since the lens of the 2D camera module 400 fixed on the rack and the lens of the 3D camera module 500 on the traveling support 300 both face upward above the milling platform 200, the planar profile image of the top of the battery pack 10 can be collected by the 2D camera module 400, and the stereoscopic profile image of the top of the battery pack 10 can be collected by the 3D camera module 500, and then the busbar coordinates on the battery pack 10 of the current specification can be directly obtained by matching the planar profile image and the stereoscopic profile image by the image processing system; the busbar milling path is generated by processing the busbar coordinates by the numerical control system, and the milling assembly 600 is driven by the numerical control system to mill the busbar 20 on the battery pack 10 according to the busbar milling path, so that the busbar 20 on the battery pack 10 of the current specification can be quickly milled, and the construction period of the battery pack 10 is shortened. The battery pack 10 is heavy and can be kept in a stationary state on the milling platform 200 to be milled by the milling assembly 600.

[0043] In the embodiment, the battery pack 10 can be a CTP battery pack (Cell to Pack, module-free battery pack) or a MTP battery pack (Module to Pack, module-to-pack battery pack), and of course the battery pack busbar milling device of the present disclosure can also be applied to mill the busbar of other types of battery packs.

[0044] It should be noted that the method of 3D camera module 500 collecting the three-dimensional profile image of the top of battery pack 10, the method of 2D camera module 400 collecting the planar profile image of the top of battery pack 10, the method of image processing system matching the planar profile image and the three-dimensional profile image, and the method of numerical control system generating the busbar milling path according to the busbar coordinates and driving milling assembly 600 to mill the busbar 20 on battery pack 10 all belong to the prior art and are not within the protection scope of the present application. The present application only protects the elements of the battery pack busbar milling device and their positions and connection relationships.

[0045] In the present embodiment, the image processing system is used to match the planar profile image and the three-dimensional profile image, specifically, the depth map of the planar profile image is matched and calibrated with the depth map of the three-dimensional profile image under the same reference. The method of depth map matching and calibration belongs to the prior art and is not within the protection scope of the present application, and thus is not described herein.

[0046] Referring to Figure 3 In some embodiments, transfer support 300 includes transfer cross rails 310 and transfer vertical rails 320. Transfer cross rails 310 are slidingly installed on the rack and horizontally arranged above milling platform 200. Transfer vertical rails 320 are vertically arranged on transfer cross rails 310 and slidingly connected with transfer cross rails 310. 3D camera module 500 and milling assembly 600 are both slidingly installed on transfer vertical rails 320. It can be understood that, since transfer cross rails 310 are horizontally arranged above milling platform 200 and transfer vertical rails 320 are slidingly connected with transfer cross rails 310, transfer vertical rails 320 can horizontally displace relative to milling platform 200 along transfer cross rails 310. Since transfer vertical rails 320 are vertically arranged on transfer cross rails 310 and 3D camera module 500 and milling assembly 600 are both slidingly installed on transfer vertical rails 320, 3D camera module 500 and milling assembly 600 can vertically lift relative to milling platform 200 along transfer vertical rails 320, so that milling assembly 600 can flexibly displace according to the busbar milling path to mill busbar 20 on battery pack 10, and 3D camera module 500 can flexibly displace to scan battery pack 10 to obtain a clearer three-dimensional profile image of the top of battery pack 10. In the present embodiment, 3D camera module 500 is a 3D line scanning camera module, but the present disclosure is not limited thereto, and other selections can be made by those skilled in the art as needed. Transfer vertical rails 320 and transfer cross rails 310 are conventional servo motor linear guides, and thus are not described herein. However, the present disclosure is only an example and does not limit transfer vertical rails 320 and transfer cross rails 310 in the battery pack busbar milling device of the present disclosure. Transfer vertical rails 320 and transfer cross rails 310 can also use other guide structures commonly used by those skilled in the art.

[0047] Referring to Figure 3In some embodiments, the migration support 300 further comprises a mounting seat 330, the mounting seat 330 being slidingly connected to the migration vertical rail 320; the 3D camera module 500 and the milling assembly 600 are both fixedly arranged on the mounting seat 330. It can be understood that, since the 3D camera module 500 and the milling assembly 600 are both fixedly arranged on the mounting seat 330, and the mounting seat 330 is slidingly connected to the migration vertical rail 320, the 3D camera module 500 and the milling assembly 600 can be simultaneously transported and synchronously displaced through the mounting seat 330, so that the 3D camera module 500 can synchronously collect the shape and thickness of the busbar 20 when the milling assembly 600 mills the busbar 20, and further so that the milling assembly 600 can adjust the moving track or speed and the depth of cutting according to the actual situation of the busbar 20, so as to further improve the precision of the milling assembly 600 in milling the busbar 20.

[0048] Please refer to Figure 3 In some embodiments, the 3D camera module 500 is externally provided with a protective shell 510. It can be understood that, by arranging the protective shell 510 on the 3D camera module 500, the 3D camera module 500 can be prevented from being injured by the iron filings generated when the milling assembly 600 mills the busbar 20.

[0049] Please refer to Figure 1 With Figure 4 In some embodiments, the rack comprises two lateral machine tables 110 and a loading beam frame 120, the two lateral machine tables 110 being respectively arranged on opposite sides of the milling platform 200; the loading beam frame 120 is arranged above the milling platform 200, and each end of the loading beam frame 120 is fixedly installed on one of the lateral machine tables 110; each end of the migration horizontal rail 310 is slidingly installed on one of the lateral machine tables 110; the 2D camera module 400 is installed on the loading beam frame 120. It can be understood that, by installing the 2D camera module 400 on the loading beam frame 120 which is arranged above the milling platform 200, the lens of the 2D camera module 400 can be kept stably directed towards the milling platform 200. At the same time, since each end of the migration horizontal rail 310 is slidingly installed on one of the lateral machine tables 110, the migration horizontal rail 310 can be stably supported, so that the migration horizontal rail 310 can more stably carry the 3D camera module 500 and the milling assembly 600 to move above the milling platform 200.

[0050] Please refer to Figure 1 With Figure 4In some embodiments, each lateral machine 110 is fixedly provided with a linear guide assembly 1110, and each end of the moving cross rail 310 is slidingly connected to a linear guide assembly 1110. It can be understood that, since each end of the moving cross rail 310 is slidingly connected to a linear guide assembly 1110 of each lateral machine 110, the moving cross rail 310 can be displaced relative to the milling platform 200 under the guidance of the linear guide assembly 1110, thereby reducing the occurrence of sliding deviation of the moving cross rail 310. In the present embodiment, the linear guide assembly 1110 is a rack and pinion linear slide module, and thus will not be described herein. Of course, the linear guide assembly 1110 is merely an example and does not limit the linear guide assembly 1110 in the battery pack busbar milling device of the present disclosure. The linear guide assembly 1110 can also use other guide rail structures commonly used by those skilled in the art.

[0051] Please refer to Figure 1 With Figure 4 In some embodiments, the rack further includes a mounting cantilever 130, which is fixedly provided on the loading beam frame 120 and located above the milling platform 200. The mounting end of the mounting cantilever 130 extends away from the loading beam frame 120 and opposite to the position of the battery pack 10. The 2D camera module 400 is provided on the mounting end of the mounting cantilever 130. It can be understood that, since the mounting end of the mounting cantilever 130 located above the milling platform 200 is opposite to the position of the battery pack 10, when the 2D camera module 400 is provided on the mounting end of the mounting cantilever 130, the lens of the 2D camera module 400 can be directed to the battery pack 10, so that the 2D camera module 400 can more completely and clearly collect the planar profile image of the top of the battery pack 10.

[0052] Please refer to Figure 1 With Figure 2 In some embodiments, the rack further includes a lifting drive 140, which is fixedly installed on the mounting end, and the telescopic rod 1410 of the lifting drive 140 is directed to the battery pack 10. The 2D camera module 400 is fixedly installed on the telescopic rod 1410 of the lifting drive 140. It can be understood that, since the telescopic rod 1410 of the lifting drive 140 is directed to the battery pack 10, by fixing the 2D camera module 400 on the telescopic rod 1410 of the lifting drive 140, the distance between the 2D camera module 400 and the battery pack 10 can be dynamically adjusted by the lifting drive 140 according to the shooting effect, so as to ensure the quality of the collected planar profile image of the top of the battery pack 10.

[0053] Please refer to Figure 3In some embodiments, the milling assembly 600 includes a fixed seat 610, a rotating driver 620, and a milling cutter 630. The fixed seat 610 is fixedly connected to the moving support 300. The rotating driver 620 is fixedly arranged on the fixed seat 610, and the power output end of the rotating driver 620 faces the milling platform 200. The milling cutter 630 is installed on the power output end of the rotating driver 620. It can be understood that, by fixing the rotating driver 620 on the fixed seat 610 fixedly arranged on the rack, and installing the milling cutter 630 on the power output end of the rotating driver 620, and by making the power output end of the rotating driver 620 face the milling platform 200, the rotating driver 620 can drive the milling cutter 630 to rotate to mill the busbar 20 of the battery pack 10 placed on the milling platform 200.

[0054] Please refer to Figure 1 With Figure 4 In some embodiments, the bottom of the milling platform 200 is provided with a pulley 210. It can be understood that, since the bottom of the milling platform 200 is provided with the pulley 210, after the busbar 20 of the battery pack 10 is milled, the milling platform 200 can be pushed to move to push the battery pack 10 to the next disassembly process, so as to improve the disassembly efficiency of the battery pack 10. In this embodiment, the pulley 210 is a heavy-duty caster, and a braking component is arranged on the heavy-duty caster. When the milling assembly 600 mills the busbar 20 of the battery pack 10, the braking component can constrain the rotation of the heavy-duty caster to make the milling platform 200 keep in a stationary state.

[0055] In some embodiments, in order to facilitate better understanding, the battery pack busbar milling equipment of the above-mentioned embodiments is described as follows:

[0056] First, the battery pack 10 is hoisted onto the milling platform 200. The 2D camera module 400 collects the planar profile image of the top of the battery pack 10. The 3D camera module 500 moves on the moving support 300 to scan the top of the battery pack frame by frame to collect the stereoscopic profile fragments of the top of the battery pack 10. The image processing system splices the stereoscopic profile fragments to obtain the stereoscopic profile image. The image processing system converts the stereoscopic profile image and the planar profile image into an RGB image and a depth image, respectively, and transforms the respective depth images into the coordinate system of the corresponding RGB image. Then, the depth image of the planar profile image and the depth image of the stereoscopic profile image are matched and calibrated under the same reference, so that the coordinates of each busbar 20 on the top of the battery pack 10 can be obtained. The numerical control system can generate a busbar milling path according to the coordinates of each busbar 20. The numerical control system drives the driver in the moving support 300 to move so that the milling assembly 600 mills the busbar 20 on the battery pack 10 according to the busbar milling path.

[0057] Compared with the prior art, the present disclosure has at least the following advantages:

[0058] The battery pack busbar milling device described above, since the lens of the 2D camera module 400 fixed on the rack and the lens of the 3D camera module 500 on the moving support 300 are both directed to the top of the milling platform 200, the 2D camera module 400 can collect the planar profile image of the top of the battery pack 10, and the 3D camera module 500 can collect the stereoscopic profile image of the top of the battery pack 10, then the image processing system can match the planar profile image and the stereoscopic profile image to directly obtain the busbar coordinates on the battery pack 10 of the current specification; the busbar coordinates are processed by the numerical control system to generate the busbar milling path, and the numerical control system drives the milling assembly 600 to mill the busbar 20 on the battery pack 10 according to the busbar milling path, so that the busbar 20 on the battery pack 10 of the current specification can be quickly milled, and the construction period of the battery pack 10 is shortened. Wherein, the battery pack 10 is heavy and can be kept in a stationary state on the milling platform 200 to be milled by the milling assembly 600.

[0059] The above-described embodiments only express several implementation manners of the present disclosure, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the utility model patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present disclosure, several modifications and improvements can be made, which all belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent should be subject to the appended claims.
