Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of copper foil-steel plate lamination, in particular to a copper foil-steel plate feeding state self-diagnosis intelligent scheduling system and method. BACKGROUND

[0002] In the PCB lamination production process, the lamination of copper foil and steel plate usually needs to complete the feeding and positioning of the upper copper foil, steel plate and lower copper foil in turn, and finally forms a sandwich structure of "copper foil-steel plate-copper foil". The existing production line adopts a single-station movable feeding and discharging structure for the feeding of copper foil and steel plate, and the next step is executed by an operator or a simple mechanical system after waiting for the end of the previous process. The real-time feeding state of the upper copper foil, lower copper foil and steel plate cannot be comprehensively monitored, which leads to the inability of the equipment to timely identify abnormalities and dynamically adjust, affecting the production continuity and safety.

[0003] With the development of automatic and intelligent manufacturing technology, in order to improve the lamination efficiency, multi-station collaborative feeding equipment gradually appears, which enables copper foil and steel plate to be prepared at the same time in different stations and to be laminated at a specific process stage. However, due to the inconsistent action frequency and beat of different material links, the traditional equipment can only rely on fixed programs to execute the process, and cannot flexibly schedule according to the real-time state of the feeding link. Once any feeding link has material missing, conveying delay or adsorption abnormality, it will cause imbalance of lamination beat, production interruption and even mis-lamination risk. SUMMARY

[0004] The purpose of the present application is to provide a copper foil-steel plate feeding state self-diagnosis intelligent scheduling system and method to solve the above problems existing in the prior art.

[0005] The present application is as follows: A copper foil-steel plate feeding state self-diagnosis intelligent scheduling system, comprising: A material supply module for providing upper copper foil, lower copper foil and steel plate for downstream lamination equipment, including three sets of feeding modules corresponding to the upper copper foil, lower copper foil and steel plate; A feeding state monitoring module for real-time acquisition and identification of the real-time state of each feeding module, the real-time state at least including: Material occupancy state: identifying whether there is material on the positioning platform and the temporary storage platform; Conveying preparation state: detecting whether the material on the lifting conveying device has reached the preset suction height; Suction locking state: detecting whether the suction and transfer device is executing suction or transfer action; Device readiness state: judging whether each device is in a ready position for safe work based on the feedback of each sensor; The intelligent scheduling module is used to execute scheduling strategies based on the operating cycle time of downstream equipment and the stacking sequence of "lower copper foil - steel plate - upper copper foil": When downstream equipment takes material from a platform and the material occupancy status changes from "material available" to "material not available", if the platform's suction lock status is "idle" and the lifting conveyor's conveying preparation status is "ready", then the suction and transfer device of this module will be immediately dispatched to take material from the lifting conveyor and replenish the empty platform. This scheduling ensures that the positioning platform and the temporary storage platform are not idle at the same time, and avoids action conflicts between devices based on the device's ready state and the suction lock state, thereby achieving continuous and uninterrupted material supply to downstream devices.

[0006] Furthermore, each of the feeding modules includes five parts: a double-layer conveyor frame, a lifting conveyor device, a positioning platform, a temporary storage platform mounted on the double-layer conveyor frame, and a suction and transfer device.

[0007] Furthermore, the double-layer conveyor frame of each feeding module adopts an upper and lower layer conveying form. One layer of the double-layer conveyor frame is used to receive the tray carrying the material conveyed from the outside, and the other layer is used to receive the empty tray conveyed by the lifting conveyor device. The double-layer conveyor frame is equipped with limit switches to monitor whether the tray has been conveyed to the correct position. This signal constitutes part of the equipment's ready state.

[0008] Furthermore, the lifting and conveying device of each feeding module includes a frame, a conveying module and a lifting module. The conveying module is used to receive the pallet carrying the material conveyed by the double-layer conveying frame. The conveying module is equipped with limit switches and photoelectric switches to monitor the conveying status of the pallet. The lifting module realizes the lifting and lowering of the conveying module through a screw assembly. Limit switches and photoelectric switches are installed on the lifting stroke to monitor the lifting position of the conveying module. These switch signals together constitute the conveying preparation state and the equipment ready state.

[0009] Furthermore, the suction and transfer devices of the upper and lower copper foil feeding modules each include a frame, a transfer component, a lifting component, and a suction component. The transfer component is equipped with a photoelectric switch and a limit switch on its lateral travel to monitor the transfer status of the copper foil. The lifting component is equipped with a magnetic reed induction switch to monitor the position of the lifting component. The suction component is equipped with a photoelectric switch to monitor whether the copper foil has been sucked up. This signal is used to determine the suction lock status.

[0010] Furthermore, the steel plate feeding module's suction and transfer device includes a frame, a steel plate transfer assembly, and a steel plate suction assembly. The frame is equipped with a photoelectric switch for monitoring the position of the steel plate transfer assembly, and the steel plate suction assembly is equipped with a magnetic reed induction switch for monitoring the lifting position of the steel plate suction assembly.

[0011] Furthermore, the positioning platform of the upper and lower copper foil feeding modules achieves the positioning of the copper foil through vacuum adsorption, and a pressure switch is set to detect the adsorption state of the copper foil.

[0012] Furthermore, the positioning platform of the steel plate feeding module achieves the positioning of the steel plate through the correction rods. Four sets of correction rods are provided above the positioning platform along the longitudinal and transverse directions of the platform, corresponding to the positioning of each side of the steel plate. Photoelectric switches are installed on the frame, with one set in the transverse and one in the longitudinal direction, to detect the real-time position of the correction rods in the corresponding directions.

[0013] A smart scheduling method for self-diagnosis of copper foil-steel plate feeding status, applied to the above system, specifically includes the following steps: S1 Real-time Status Sensing and Diagnosis: Data is collected in real time by various sensors, and the material supply status monitoring module continuously calculates and outputs the material occupancy status, conveying preparation status, suction locking status and equipment readiness status of each module. S2 Event-Driven Intelligent Scheduling: The intelligent scheduling module listens for status changes. When the material picking by downstream equipment causes the material occupancy status of a certain platform to change to "no material", this is used as a scheduling trigger event. Before executing the scheduling, it verifies whether the conveying preparation status of the target lifting conveyor is "ready" and confirms that the pick-up locking status of the transfer device of this module is "idle". S3 Self-Diagnosis and Closed-Loop Control: During the transfer process, if the sensor detects adsorption failure, material shortage, or transfer timeout, the self-diagnosis module immediately updates the status to abnormal, and the intelligent scheduling module terminates the current instruction and executes the predetermined retry or fault-tolerant process to achieve closed-loop control.

[0014] Compared with the prior art, the embodiments of the present invention achieve the following beneficial effects: This invention achieves real-time material feeding status identification by arranging sensing and detection elements at key nodes in the copper foil and steel plate feeding chain. The system can accurately determine whether the material is in place, whether the empty tray has been recovered, whether the adsorption is successful, and whether there are any abnormalities in the feeding chain, thereby realizing automatic identification and self-diagnosis of the feeding status and effectively avoiding problems such as misaligned feeding, empty suction, and shutdown for troubleshooting caused by misjudgment of status.

[0015] Building upon the self-diagnosis of the material supply status, this invention further constructs a multi-station synchronous intelligent scheduling mechanism based on real-time status. When the material in any material supply link is not ready, the scheduling system can intelligently adjust the picking order, perform buffering actions, or wait for processing based on the detection status, ensuring that the material preparation rhythm of the upper copper foil, lower copper foil, and steel plate remains consistent. Through this dynamic scheduling control logic, it is possible to avoid imbalances in the overall line rhythm, misalignment of overlapping parts, or main equipment stoppages caused by delays in a single material supply link, significantly improving system operational stability, material supply continuity, and production efficiency, and achieving automated intelligent material supply control for three stations.
