Description

Technical Field

[0001] The utility model belongs to the technical field of battery recycling equipment, in particular to a battery connecting piece cutting device. Background Art

[0002] With the rapid development of new energy technologies, new energy technologies are widely used in transportation and handling equipment, among which power batteries, as one of the core components of these technologies, play a vital role. However, as the use time accumulates, the performance of power batteries will gradually decay. When their performance drops below the design requirements, they will no longer be able to meet the demand for power. In view of this reality, it can be foreseen that in the near future, the recycling of power batteries will become an important topic and peak in the industry.

[0003] The battery body of a power battery is generally composed of several groups of battery cells connected together. These battery cells are all provided with electrodes. The electrodes of the battery cells are electrically connected through electrode connecting sheets, so that the battery cells are connected together to form a battery body. Therefore, the connecting sheets need to be cut off during battery recycling. Specifically, the battery body is placed on a transfer mechanism, which transports the battery body to a cutting position, and the cutting device at the cutting position cuts the connecting sheets. The existing battery connecting sheets are arranged at the top and side of the battery body. When cutting the side connecting sheets, in order to prevent the cutting device from interfering with the transfer mechanism at the bottom of the battery body, it is usually necessary to increase the height between the battery body and the transfer mechanism relative to cutting the top connecting sheet. A common practice is to use a heightened carrier. This method is very cumbersome to operate during production change, which not only increases the cost of equipment and personnel, but also reduces work efficiency, resulting in the existing cutting equipment being difficult to apply to the automated recycling of the two types of batteries with connecting sheets arranged on the top or side.

The battery 101 is placed on the roller 11, and the transportation of the battery 101 can be achieved by driving the roller 11 to rotate.

[0024] See also Figures 4 to 6 The lifting mechanism 2 is used to lift the battery 101 located at the cutting position 10 to a preset height. In this embodiment, the lifting mechanism 2 includes a base 21, a bracket 22 located above the base 21, and a driving device 23 arranged on the base 21 for driving the bracket 22 to rise and fall.

The above-mentioned bracket 22 can drive the battery 101 to rise and fall, and can also drive the battery 101 to rotate. The offset angle of the battery 101 can be adjusted by rotating the support plate 222.

[0026] See also Figure 5 and Figure 6 As an improved solution, it also includes an offset recognition camera disposed above the cutting position 10, the offset recognition camera is used to identify the offset angle of the currently lifted battery 101 relative to the reference, the support plate 222 is provided with a rotating shaft 224 rotatably connected to the lifting platform 221 corresponding to the axis, the lifting platform 221 is provided with a telescopic cylinder 24, the telescopic cylinder 24 is provided with a push rod 241 that can be extended and retracted in a direction parallel to the support plate 222, the push rod 241 is connected to a pull rod 242 connected to the support plate 222, the telescopic cylinder 24 drives the pull rod 242 to extend or retract according to the offset angle, so as to drive the support plate 222 to rotate around the rotating shaft 224, and the above-mentioned setting method realizes the automatic adjustment of the offset angle of the battery 101. It should be noted that the transfer mechanism 1 at least adjusts the gap between the two rollers 11 through which the bottom support 223 passes to allow the bottom support 223 to rotate to a certain amplitude.

[0027] In other embodiments, the telescopic cylinder 24 may also be other existing drives, such as a linear motor.

[0028] See also Figure 5 and Figure 6 The upper end of the lifting platform 221 is provided with a plurality of bull's eye bearings 25 that are in rolling contact with the bottom end of the support plate 222 , and the bull's eye bearings 25 provide support for the rotation of the support plate 222 .

[0029] The driving device 23 is preferably a driving cylinder or a driving cylinder.

[0030] See also Figure 5 and Figure 6 In order to make the bracket 22 rise and fall smoothly, a guide rod 26 is provided at the bottom of the lifting platform 221, and a guide seat 27 that slidably cooperates with the guide rod 26 is fixedly provided on the base 21.

[0031] See also Figure 1 The driving mechanism 3 of this embodiment includes a robotic arm 301 with at least six rotating joints, and a driving rail 302 arranged above the transfer mechanism 1 for driving the robotic arm 301 to move along the transportation direction of the transfer mechanism 1. It is preferably a six-axis robotic arm 301, and the laser cutting module 4 and the visual recognition module 5 are arranged on the end rotating joint of the robotic arm 301.

[0032] See also Figure 1 The rotating joint at the end of the robot arm 301 is connected to a mounting seat 31, the laser cutting module 4 includes a laser cutting head 41 arranged on one side of the mounting seat 31, and the laser cutting head 41 is preferably a galvanometer laser cutting head. The visual recognition module 5 includes a camera 51 arranged on the mounting seat 31 and located adjacent to the galvanometer laser cutting head. The lens of the camera 51 and the orientation of the galvanometer laser cutting head are located on the same side. The visual recognition module 5 is driven by the driving mechanism 3 to collect the position data required for cutting the top or side connecting piece 102 of the battery 101. The laser cutting head 41 can be controlled by the driving mechanism 3 to achieve cutting direction. Figure 2 The cut top connecting piece 102 shown or Figure 1 As shown in the cutting of the side connecting piece 102 , in this embodiment, the cutting of the top connecting piece 102 and the side connecting piece 102 needs to be performed when the battery 101 is lifted to a preset height, so that the offset angle of the battery 101 can be adjusted before cutting.

[0033] The working principle of the utility model is as follows: the battery 101 is loaded to the loading end of the transfer mechanism 1, and the transfer mechanism 1 transports the battery 101 to the cutting position 10. When it reaches the cutting position 10, the transfer mechanism 1 pauses, and the bracket 22 of the lifting mechanism 2 rises to make the bottom support 223 pass through the gap between the rollers 11 to lift the battery 101 to a preset height. At this time, the offset recognition camera scans the offset angle of the battery 101 relative to the reference at a top-down angle, and the telescopic cylinder 24 extends and retracts according to the offset angle controller push rod 241, thereby driving the bracket 22 to rotate around the rotating shaft 224 to correct the angle of the battery 101. The above-mentioned algorithm for adjusting the angle according to the offset angle does not belong to the invention point of the utility model and is not explained here. Subsequently, the driving mechanism 3 drives the laser cutting module 4 and the visual recognition module 5 to move to the side of the battery 101 where the connecting piece 102 is provided, specifically including the top or the side, and rotates the laser cutting head 41 and the camera 51 of the visual recognition module 5 toward the connecting piece 102. The camera 51 first collects the contour features and base point coordinates of the connecting piece 102 to control the driving mechanism 3 to adjust the position of the laser cutting module 4 according to the contour features and base point coordinates, and then the galvanometer laser cutting head cuts off the connecting piece 102. When the cutting of one cutting piece is completed, the driving mechanism 3 drives the laser again. The cutting module 4 and the visual recognition module 5 move to the position of the next connecting piece 102, and cut the next connecting piece 102 as described above. Similarly, after the cutting of each connecting piece 102 is completed, the driving mechanism 3 is reset, the lifting mechanism 2 drives the battery 101 to descend, the bottom support 223 leaves the gap between the rollers 11, and the transfer mechanism 1 starts to continue to transport the battery 101. It should be noted that the visual recognition module 5, the offset recognition camera, and the galvanometer laser cutting head involved in the utility model are prior arts, and their working principles do not belong to the invention point of the utility model, so they are not described in detail.

[0034] Compared with the prior art, the cutting equipment provided by the utility model is equipped with a lifting mechanism 2, so as to selectively lift the battery 101 to a preset height at the cutting position 10 according to the position of the required cutting connecting piece 102, so as to achieve that when cutting the side connecting piece 102, the driving mechanism 3, the visual recognition module 5, the laser cutting module 4, etc. will not interfere with the transfer mechanism 1, so that when changing production, the height relationship between the battery 101 at the cutting position 10 and the transfer mechanism 1 can be flexibly adjusted to adapt to the cutting of the side connecting piece 102 and the top connecting piece 102.

Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model.
