Description

Technical Field

[0001] This utility model relates to the field of electrode forming machine technology, and more specifically, to a forming mechanism of an electrode forming machine. Background Technology

[0002] A battery is a device that converts chemical energy into electrical energy, and the electrode is the part of the battery responsible for conducting electricity. Battery electrodes are generally divided into two types: anode and cathode. Their functions are to carry ions during charging and discharging, respectively, converting chemical energy into electrical energy. The quality, structure, and manufacturing process of the electrode material have a significant impact on battery performance. An electrode forming machine is a piece of equipment used in the battery manufacturing process, mainly for processing battery electrodes into the required shape and size. Existing electrode forming methods, using stamping dies, make it inconvenient to collect the electrodes, and some electrodes are difficult to fall off the base material, affecting the smooth progress of electrode forming. Therefore, we propose a forming mechanism for an electrode forming machine. Utility Model Content

[0029] In this embodiment, multiple cutting dies 12 are located directly above multiple dropping holes 8, ensuring that the cutting dies 12 can fall from the dropping holes 8 after the electrode sheet is formed.

[0030] For details, please refer to Figure 1 The conveying support mechanism 4 includes two front supports 25 and two rear supports 28 fixedly connected to the top surface of the workbench 1.

[0038] Working principle: In use, firstly, the servo motor 27 is started to drive the lower front support roller 26 to rotate clockwise intermittently. At the same time, the substrate is inserted between the two front support rollers 26. The front support rollers 26 drive the substrate to move forward intermittently. Then, the vacuum pump 17 is started so that its input end can draw air into the inner cavity of the receiving box 15 through the wire mesh 16. The negative pressure of the receiving box 15 causes the receiving pipe 14, the dropping groove 6, and the dropping hole 8 to generate suction. In addition, the control panel 30 controls the first electric hydraulic rod 10 to drive the upper mold 11 to move up and down intermittently. When the substrate moves to the lower... When the substrate is above the mold 7, the cutting mold 12 at the bottom of the upper mold 11 is used to stamp the substrate to form the electrode sheet. At the same time, the suction of the dropping hole 8 causes the electrode sheet to fall and be collected in the receiving box 15. Then the substrate continues to move, and the connecting block 23 and the ejector pin 24 are controlled to move up and down by the control panel 30. The ejector pin 24 pushes the electrode sheet that has not fallen off the substrate, so that the electrode sheet falls from the dropping frame 21 into the rear receiving box 19 for collection. Finally, the stamped electrode sheet is discharged from the two rear support rollers 29.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
