[0030] From the above description, it can be seen that the beneficial effect of the present invention is that: the waste discharge device identifies the pole piece waste on the pole piece carrying platform 1 through the identification camera 3. When the pole piece waste is identified, the first Y-axis drive component 6 cooperates with the Z-axis drive component 7 to drive the material picking component 8 close to the pole piece carrying platform 1 to pick up the pole piece waste. Then the X-axis drive component 5 drives the waste carrying plate 4 to move to the top of the pole piece carrying platform 1 to receive the pole piece waste, thereby quickly and efficiently removing the pole piece waste generated in the stacking process, effectively improving the yield of the battery cell.

[0031] Furthermore, it also includes a second Y-axis driving component 9, which is driven and connected to the waste carrying plate 4 to drive the waste carrying plate 4 to move closer to or away from the pole piece carrying platform 1.

[0032] From the above description, it can be seen that the second Y-axis driving assembly 9 can move the scrap carrier 4 along the Y-axis direction, thereby keeping the scrap carrier 4 away from other mechanisms, making it easier for staff to collect the electrode scraps on the scrap carrier 4.

[0033] Furthermore, the first Y-axis driving assembly 6 and / or the Z-axis driving assembly 7 is a linear module.

[0034] It can be seen from the above description that the linear module has high positioning accuracy, which is conducive to the material picking component 8 accurately picking up the pole piece waste on the pole piece supporting platform 1.

[0035] Furthermore, an X-axis guide rod 21 is provided on the frame 2 , and the waste carrying plate 4 is slidably engaged with the X-axis guide rod 21 .

[0037] Furthermore, the X-axis driving assembly 5 is a linear cylinder.

[0038] As can be seen from the above description, using a linear cylinder to drive the waste carrying plate 4 is beneficial to increasing the speed of the waste carrying plate 4, thereby improving the efficiency of the waste discharge device.

[0039] Furthermore, the material taking component 8 is a suction cup.

The locking piece 23 is used to lock the relative position relationship between the Y-axis mounting rod 22 and the recognition camera 3.

[0044] As can be seen from the above description, the staff can adjust the position of the recognition camera 3 along the circumference of the Y-axis mounting rod 22 so that the recognition camera 3 can be aligned with different positions of the battery electrode.

[0045] Furthermore, it also includes a mounting bracket 24 and a connecting component 25, and the recognition camera 3 is slidably mounted on the Y-axis mounting rod 22 through the mounting bracket 24; a long hole 241 is provided on the mounting bracket 24, and the recognition camera 3 is detachably connected to the long hole 241 through the connecting component 25, and the length direction of the long hole 241 extends along the X-axis direction.

[0046] As can be seen from the above description, the staff can adjust the position of the recognition camera 3 along the length direction of the long hole 241 so that the recognition camera 3 can be aligned with different positions of the battery electrode.

[0047] Please refer to Figures 1 to 3, Embodiment 1 of the present invention is: a waste discharge device for collecting waste on a pole piece carrying platform 1, comprising a frame 2 and an identification camera 3, a waste carrying plate 4, an X-axis drive assembly 5, a first Y-axis drive assembly 6, a Z-axis drive assembly 7 and a picking assembly 8 installed on the frame 2; the identification camera 3 is arranged directly above the pole piece carrying platform 1; the waste carrying plate 4 is arranged above the pole piece carrying platform 1, and the X-axis drive assembly 5 is driven and connected to the waste carrying plate 4 to drive the waste carrying plate 4 close to or away from the pole piece carrying platform 1; the picking assembly 8 is arranged above the waste carrying plate 4, and the first Y-axis drive assembly 6 and the Z-axis drive assembly 7 are respectively driven and connected to the picking assembly 8, and the first Y-axis drive assembly 6 and the Z-axis drive assembly 7 are used to drive the picking assembly 8 to pick up the waste on the pole piece carrying platform 1.

In this embodiment, the second Y-axis drive assembly 9 is disposed on a mounting base and is a linear module.

[0050] There are multiple recognition cameras 3. In this embodiment, the recognition cameras 3 are CCD cameras. There are four recognition cameras 3, each used to identify the four rounded corners of the battery electrode. In other embodiments, the number of recognition cameras 3 can be one, two, three, or more.

[0051] The frame 2 is also provided with a Y-axis mounting rod 22 and a locking member 23. The identification camera 3 is mounted on the Y-axis mounting rod 22 and is slidable along the axial direction of the Y-axis mounting rod 22. The locking member 23 is used to lock the relative position between the Y-axis mounting rod 22 and the identification camera 3. In this embodiment, the identification camera 3 is slidably mounted on the Y-axis mounting rod 22 via a slide. The locking member 23 is preferably a bolt that passes through the slide and abuts against the Y-axis mounting rod 22. As will be readily understood, the position of the identification camera 3 can be adjusted along the circumference of the Y-axis mounting rod 22 to align the identification camera 3 with different positions of the battery electrode.
