Description

Technical Field

[0001] The utility model belongs to a copper-aluminum composite plate coiling machine, and relates to automatic deviation-correcting equipment for the copper-aluminum composite plate coiling machine. Background Art

[0002] Copper-aluminum composite panels have been widely used in decoration and furnishing industries, automotive precision electrical parts, new energy batteries, circuit metal substrates, military and aerospace industries, shipbuilding, high and low voltage distribution devices, transformers, containers, electrical hardware, tableware and kitchenware, and other industries.

[0003] Due to the unevenness of the material, copper-aluminum composite panels are prone to deviation and curling during the coiling process, resulting in low production efficiency and poor product surface quality. The commonly used method is to use a device with a guide wheel for guidance, but it cannot meet the demand for precise deviation correction during the coiling process of copper-aluminum composite panels. Faced with the market's urgent demand for high-quality and high-efficiency production, a new solution is needed. Summary of the invention

[0004] In order to overcome the shortcomings of the existing technology, the utility model provides an automatic deviation correction device for a copper-aluminum composite plate coiler with a simple structure, good deviation correction accuracy, high speed and stable operation. It improves the adjustment accuracy of the piston rod of the deviation correction hydraulic cylinder while preventing excessive adjustment, thereby realizing automatic deviation correction of the copper-aluminum composite plate coiler.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] The invention discloses an automatic deviation correction device for a copper-aluminum composite plate coiler, comprising a deviation correction hydraulic cylinder, a sliding base, a coiler, a material pressing mechanism, a material pushing mechanism, a pinch roller, a visual recognition system, a displacement sensor and a roller frame, wherein the material pressing mechanism and the material pushing mechanism are fixed above the coiler to assist in coiling and uncoiling; a guide rail is provided at the bottom of the coiler, and the guide rail can slide after cooperating with the sliding base, the deviation correction hydraulic cylinder is installed parallel to the guide rail of the coiler, the piston end of the deviation correction hydraulic cylinder is fixed on the coiler to drive the coiler to move, and the material pressing mechanism is used to press the coil tightly during the coiling process of the coiler to prevent the coil from loosening; the visual recognition system is used to monitor the edge position of the copper-aluminum composite plate in real time, and when the edge is offset, the coiler slides slowly on the sliding base under the action of the deviation correction hydraulic cylinder and the displacement sensor to adjust to the correct position, and the roller frame is retracted after the copper-aluminum composite plate is coiled, and the material pushing mechanism pushes the coil out for transportation.

[0007] Furthermore, the winder includes a slide, a reduction motor, a winding frame and a supporting roller. The slide is embedded in the slide rail of the sliding base so that the winder as a whole can slide along the direction of the slide rail. A limit baffle is installed at the end of the slide rail of the sliding base to limit the stroke of the winder. The reduction motor is fixedly connected to the winding frame of the winder by bolts, and drives the supporting roller to rotate after being decelerated by the reduction gear box. There is a reverse oblique groove on the winding shaft of the supporting roller. After the head of the copper-aluminum composite plate is stuck in the reverse oblique groove, it is wound around the supporting roller driven by the rotation of the supporting roller.

[0008] Furthermore, the pressing mechanism includes a crankshaft, a pressing hydraulic cylinder and a pressing roller. One end of the crankshaft is fixed above the winding frame, and the pressing roller is installed on the other end of the crankshaft through a pressing roller seat. The pressing mechanism drives the crankshaft to rotate by continuously extending the piston rod of the pressing hydraulic cylinder, so that the pressing roller is close to the copper-aluminum composite plate coil, preventing the coil from becoming loose during winding. After the coiling is completed and fixed, the piston rod of the pressing hydraulic cylinder retracts to keep the pressing roller away from the coil, making it easier for the pushing mechanism to push out the coil.

[0009] Furthermore, the pushing mechanism includes a pushing plate, a pushing fixing seat and a pushing hydraulic cylinder. The pushing mechanism is fixed above the winding frame through the pushing fixing seat, the pushing plate is fixed to the end of the pushing hydraulic cylinder, and the pushing hydraulic cylinder extends to push the copper-aluminum composite plate coil out to achieve unloading.

[0010] The displacement sensor is fixed on a sliding base, and a measuring rod of the displacement sensor is fixed on a coiler, so as to convert the moving distance of the coiler into an electrical signal and transmit it to a host computer.

[0011] The visual recognition system includes a camera fixing frame, a light source fixing frame, a light source and a camera. The camera is fixed at the end of the camera fixing frame, and the light source is fixed at the upper part of the light source fixing frame. The camera continuously collects real-time images of the copper-aluminum composite plate, and uploads the collected images to a host computer. The host computer uses an image processing algorithm to identify the edge position of the copper-aluminum composite plate, and subtracts the identified edge position information from the edge position when the plate is in the center position. The position of the copper-aluminum composite plate coil is adjusted by extending and retracting the piston rod of the correction hydraulic cylinder according to the error control. The displacement sensor transmits the displacement value of the coiler to the host computer in real time, while improving the adjustment accuracy of the piston rod of the correction hydraulic cylinder and preventing over-adjustment, thereby realizing automatic correction of the copper-aluminum composite plate coiling.

[0012] In the utility model, when the visual recognition system detects that the edge deviation of the copper-aluminum composite plate exceeds the set threshold value, the visual recognition system uploads the collected image to the host computer, and the host computer uses an image processing algorithm to identify the edge position of the copper-aluminum composite plate, and makes a difference between the identified edge position information and the edge position when the plate is in the center position, and adjusts the position of the copper-aluminum composite plate coil by extending and retracting the piston rod of the correction hydraulic cylinder according to the error control. The displacement sensor transmits the displacement value of the coiler to the host computer in real time, which can improve the adjustment accuracy of the piston rod of the correction hydraulic cylinder while preventing excessive adjustment, thereby realizing automatic correction of the copper-aluminum composite plate coiling.
