Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lithium battery production equipment, in particular to a device for improving the accuracy of deviation correction electric eye edge grasping of lithium battery equipment. Background Art
[0002] Existing lithium battery substrates (such as pole pieces, diaphragms, etc.) need to maintain precise edge positions during the winding, coating, slitting and other processes. In "Automatic Correction Technology in Lithium Battery Production Lines" (published in "Battery Technology Journal" Issue 3, 2022), a variety of automatic correction technologies for lithium battery production lines are introduced, including the application of photoelectric sensors and laser sensors, but no specific improvement measures to improve the accuracy of the electric eye's edge grasping are proposed; and due to the fluctuation of the substrate tension, one side of the substrate will shake during coating. Such abnormalities will cause the correction electric eye to misjudge the edge grasping, which will lead to misalignment during reel change or normal coating.
[0003] Therefore, when the existing deflection-correcting electric eye is used, the substrate / pole edge collapses due to uneven pole tension, the pole is unstable, and there is no stable adjustment mechanism, which leads to large edge grasping errors and edge grasping failures of the deflection-correcting electric eye. Utility Model Content
[0004] The utility model aims to solve the problem that the existing deflection-correcting electric eye has no stable adjustment mechanism when in use, and the deflection-correcting electric eye has large edge-catching error and fails to catch the edge.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A device for improving the edge-grabbing accuracy of the deflection correction electric eye of lithium battery equipment is characterized by: comprising an adjustable deflection correction pressure roller for pressing both sides of the substrate to prevent the edge of the substrate from shaking and improving the edge-grabbing accuracy of the deflection correction electric eye, and a pressure roller adjustment component arranged at both ends of the deflection correction pressure roller for manually adjusting the tension of the deflection correction pressure roller, the deflection correction pressure roller is arranged below the deflection correction electric eye on the deflection correction mechanism; a group of mounting brackets are symmetrically arranged on both sides of the deflection correction mechanism.
[0007] Further improvement is that: the pressure roller adjustment assembly includes a gantry bracket detachably mounted on the mounting bracket, a screw rotatably connected to the gantry bracket, and a seat bearing adjustably arranged in the gantry bracket, one end of the screw is rotatably connected to the bottom of the gantry bracket, and the other end of the screw extends out of the top of the gantry bracket, and a screw slider is threadedly connected to the part of the screw located in the gantry bracket, and the roller shafts at both ends of the deviation correction pressure roller are hinged on the corresponding seat bearings at both ends, and the screw slider is fixedly connected to the seat bearing toward one end of the deviation correction pressure roller.
[0008] A further improvement is that the other end of the screw rod extends out of the top end of the gantry bracket and is fixedly connected to an adjusting knob.
[0009] A further improvement is that: a group of guide rails are symmetrically arranged on the two inner side walls of the gantry bracket, a group of guide rail sliders adapted to the guide rails are arranged at both ends of the screw slider, and the guide rail sliders are slidably arranged on the guide rails.
[0010] A further improvement is that the gantry bracket is detachably mounted on the mounting bracket through the mounting seat and screws.
[0011] A further improvement is that the length of the deviation-correcting pressure roller is greater than the width of the substrate.
[0012] Compared with the existing technology, the above technical solution has the following beneficial effects:
[0013] A deflection correction pressure roller is provided. When the substrate passes through the deflection correction pressure roller, the deflection correction pressure roller presses both sides of the substrate to prevent the edge of the substrate from shaking, thereby improving the accuracy of the electric eye edge grasping, and thus improving the deflection correction accuracy of the equipment;
[0014] The newly added adjustment component is used to adjust the tension of the deviation correction roller. It can be adjusted as needed to meet the deviation correction requirements in different situations, further improve the accuracy of deviation correction, and thus improve product quality and production efficiency.
