[0038] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0039] First, combine Figures 1-8 This invention describes an electrode cutting compensation mechanism according to an embodiment of the present invention, used for cutting electrodes.

[0040] like Figures 1-8 As shown, an embodiment of the present invention provides an electrode cutting compensation mechanism, comprising: a base plate 1, a positioning component 2, a compensation component 3, and a cutting component 4;

[0041] The base plate 1 is provided with a positioning component 2, a compensation component 3, and a cutting component 4;

[0042] The positioning component 2 includes: a positioning camera 21;

[0043] The positioning camera 21 is used to photograph the tabs of the electrode sheet and compare the photographed tab positions with the theoretical tab positions.

[0044] The compensation component 3 includes: a compensation mechanism, a pressing mechanism 6, and an angle deflection mechanism 5;

[0045] The compensation mechanism is provided with two oppositely arranged deflection mechanisms 5, which are respectively arranged on both sides of the electrode sheet. The compensation mechanism is used to drive the two deflection mechanisms 5 to move synchronously to compensate for the deviation of the electrode sheet. The pressing mechanism 6 is used to drive the deflection mechanisms 5 to press the electrode sheet at a deflection angle.

[0046] The cutting assembly 4 includes: a drive mechanism 46 and a cutting blade 47;

[0047] The output end of the drive mechanism 46 is connected to the cutting tool 47, which is used to cut the electrode sheet.

[0048] In this application, the electrode sheet passes sequentially through the positioning component 2, the compensation component 3, and the cutting component 4. The positioning camera 21 takes a picture of the electrode tab of the electrode sheet, compares the position of the photographed electrode tab with the theoretical position of the electrode tab, and calculates the difference between the two. The compensation mechanism moves the electrode sheet that passes through the deflection mechanism 5 according to the difference. After the electrode sheet is moved to the theoretical position, the drive mechanism 46 drives the cutting tool 47 to cut the electrode sheet, thereby ensuring that the size of each electrode sheet is correct.

[0049] This application can detect the tab position of each electrode sheet and then make corresponding compensation to ensure the correct size of each electrode sheet. This compensation method takes pictures and measures the position of the electrode sheet before it is cut, and structurally minimizes the distance between the detection position and the cutting position, thereby reducing errors in the transportation process and further improving the product qualification rate.

[0050] like Figures 1-2 As shown, the base plate 1 is provided with an adjustment slide rail 11 and a fixing mechanism 12. The positioning component 2, the compensation component 3 and the cutting component 4 are all slidably arranged on the adjustment slide rail 11.

[0051] In this embodiment, the positioning component 2, the compensation component 3, and the cutting component 4 are all slidably mounted on the adjustment slide rail 11. The positions of the positioning component 2, the compensation component 3, and the cutting component 4 on the base plate 1 can be adjusted by unlocking the fixing mechanism 12, thereby adjusting the distance between the positioning component 2, the compensation component 3, and the cutting component 4, so that this application can cut electrode sheets of different models.

[0052] like Figures 3-4 As shown, the positioning component 2 includes: a positioning frame 22 and a feeding plate 23;

[0053] The positioning frame 22 is mounted on the base plate 1, the feeding plate 23 is fixed on the positioning frame 22, the electrode sheet passes through the feeding plate 23, and the positioning camera 21 is fixed on the positioning frame 22 and located above the feeding plate 23. The positioning camera 21 is used to take pictures of the electrode sheet on the feeding plate 23.

[0054] The positioning component 2 further includes: an upper limit plate 24 and a lower limit plate 25;

[0055] The upper limit plate 24 and the lower limit plate 25 are both fixed on the positioning frame 22. The upper limit plate 24 and the lower limit plate 25 are arranged opposite to each other and have a certain gap in between. The gap is set corresponding to the feeding plate 23.

[0056] In this application, after the electrode passes through the gap between the upper limit plate 24 and the lower limit plate 25, the electrode passes through the feeding plate 23, so that the positioning camera 21 can take pictures of the electrode tabs of the electrode on the feeding plate 23.

[0057] like Figures 5-6 As shown, the compensation mechanism includes: a compensation frame 31, a compensation base plate 32, a compensation slide rail 33, a compensation slide plate 34, and a compensation motor 35;

[0058] The compensation frame 31 is mounted on the base plate 1, the compensation base plate 32 is fixed on the compensation frame 31, the compensation slide rail 33 is fixed on the compensation base plate 32, the compensation slide plate 34 is slidably mounted on the compensation slide rail 33, the output end of the compensation motor 35 is connected to a compensation lead screw, the compensation lead screw is connected to the compensation slide plate 34, the compensation motor 35 is used to drive the compensation slide plate 34 to move on the compensation slide rail 33, and the two deflection mechanisms 5 are arranged opposite to each other on the compensation slide plate 34.

[0059] The compensation motor 35 drives the compensation screw to rotate, causing the compensation slide plate 34 to slide on the compensation slide rail 33, thereby adjusting the position of the two deflection mechanisms 5 on the compensation slide plate 34, and thus adjusting the position of the electrode between the two deflection mechanisms 5 to compensate for the deviation of the electrode.

[0060] like Figures 5-6 As shown, the deflection mechanism 5 includes: a bottom straight mechanism 51, a deflection base plate 52, a deflection pressure plate 53, a guide post 54, and a return spring 55;

[0061] The bottom linear mechanism 51 is mounted on the compensation slide plate 34. The output end of the bottom linear mechanism 51 is connected to the deflection plate 52. The pressure deflection plate 53 is located above the deflection plate 52. A guide post 54 is provided between the deflection plate 52 and the pressure deflection plate 53. A reset spring 55 is provided on the guide post 54. The output end of the pressing mechanism 6 is connected to the pressure deflection plate 53.

[0062] In this embodiment, the position of the deflection base plate 52 can be adjusted by the bottom linear mechanism 51, thereby adjusting the distance between the two deflection mechanisms 5, so that the deflection mechanism 5 can deflect the electrode sheets of different types. The pressing mechanism 6 can drive the deflection plate 53 to move downward, so that the deflection plate 53 deflects the electrode sheets on the deflection base plate 52. The deflection plate 53 can be reset by the return spring 55 on the guide post 54.

[0063] like Figures 5-6 As shown, the pressing mechanism 6 includes: a pressing motor 61, an eccentric wheel 62, a vertical plate 63, a horizontal plate 64, a top linear mechanism 65, and a pressing plate 66;

[0064] The pressure motor 61 is fixed on the top of the compensation frame 31. The output end of the pressure motor 61 is connected to the eccentric wheel 62. One end of the vertical plate 63 is connected to the eccentric wheel 62. The other end of the vertical plate 63 is connected to the horizontal plate 64. The lower surface of the horizontal plate 64 is provided with a top linear mechanism 65. The top linear mechanism 65 is set corresponding to the bottom linear mechanism 51. The pressure plate 66 is set at the output end of the top linear mechanism 65. The pressure plate 66 is connected to the pressure angle plate 53.

[0065] The pressure motor 61 drives the eccentric wheel 62 to rotate, causing the eccentric wheel 62 to drive the vertical plate 63 to move up and down during the rotation, causing the horizontal plate 64 to drive the top linear mechanism 65 and the pressure plate 66 to move up and down. The pressure plate 66 is connected to the pressure angle plate 53, so that the pressure angle plate 53 presses the electrode on the deflection base plate 52 at a deflection angle.

[0066] like Figures 7-8 As shown, the cutting assembly 4 includes: a cutting frame 41, a feeding roller 42, a feeding motor 43, a pressure roller 44, and a pressure cylinder 45;

[0067] The cutting frame 41 is mounted on the base plate 1. The feeding motor 43 is mounted on one side of the cutting frame 41. The output end of the feeding motor 43 is connected to the feeding roller 42. The pressing cylinder 45 is mounted on the top of the cutting frame 41. The output end of the pressing cylinder 45 is connected to the pressing roller 44. The electrode passes between the feeding roller 42 and the pressing roller 44.

[0068] The feeding motor 43 drives the feeding roller 42 to rotate and transport the electrode sheet to the cutting tool 47. The pressing cylinder 45 drives the pressing roller 44 to press the electrode sheet on the feeding roller 42, so that the electrode sheet passes between the feeding roller 42 and the pressing roller 44 and is flatter, making it easier for the cutting tool 47 to cut the electrode sheet.

[0069] like Figures 7-8 As shown, the cutting assembly 4 includes: a waste hood 48, a waste pipe 49, and a waste fan;

[0070] The waste hood 48 is fixed on the cutting frame 41 and is set corresponding to the cutting tool 47. One end of the waste pipe 49 is connected to the waste hood 48 and the other end is connected to the output end of the waste blower.

[0071] The debris generated after the cutting blade 47 cuts the electrode sheets is collected by the waste hood 48 and transported out through the waste pipe 49 to ensure the cleanliness of the workshop.

[0072] Above, refer to Figures 1-8 This invention describes an electrode cutting compensation mechanism according to an embodiment of the present invention. The electrode passes sequentially through the positioning component 2, the compensation component 3, and the cutting component 4. The positioning camera 21 takes a picture of the electrode tab of the electrode, compares the position of the photographed electrode tab with the theoretical position of the electrode tab, and calculates the difference between the two. The compensation mechanism moves the electrode passing through the deflection mechanism 5 according to the difference. After the electrode is moved to the theoretical position, the driving mechanism 46 drives the cutting tool 47 to cut the electrode, thereby ensuring that the size of each electrode is correct.

[0073] This application can detect the tab position of each electrode sheet and then make corresponding compensation to ensure the correct size of each electrode sheet. This compensation method takes pictures and measures the position of the electrode sheet before it is cut, and structurally minimizes the distance between the detection position and the cutting position, thereby reducing errors in the transportation process and further improving the product qualification rate.
