The negative electrode current collector of lithium batteries is usually made of copper foil, which provides a path for electron transmission and is also a place for the deposition and deintercalation of lithium ions.

[0003] The production process of lithium battery copper foil mainly includes the following steps: copper dissolution: first, copper wire and other raw materials are placed in a tank containing sulfuric acid, and an oxidation reaction is carried out by heating and introducing air (usually compressed air) to dissolve the copper to form a copper sulfate solution; filtering, cooling, foil production, post-processing and slitting.

[0004] In the production process of lithium battery copper foil, copper dissolving and feeding is a key link, and its quality and efficiency directly affect the performance and production cost of copper foil.

It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0041] like Figure 1-Figure 3As shown, a lithium battery copper foil dissolving intelligent feeding process disclosed in the present invention comprises the following steps:

[0042] S1. Calibration;

[0043] The position of the entire operation area is calibrated according to the position of the reserve rack in the on-site operation area, the placement point of each copper coil on the reserve rack, the position of the copper melting tank cover, and the feeding point of each copper melting tank; and the calibrated coordinates are imported into the remote control system;

[0044] S2, open the cover;

[0045] According to the calibrated copper melting tank position coordinates, the remote control system controls the crane to move to the copper melting tank where materials need to be fed, opens the tank cover, moves the tank cover to the top of the adjacent copper melting tank, and stacks the tank cover on the copper melting tank cover;

[0046] S3, taking and feeding materials;

[0047] According to the calibrated position of the reserve rack and the coordinates of the copper coil placement point, the remote control system controls the crane to move to the top of the corresponding copper coil on the reserve rack, hoist the copper coil, and then move to the corresponding feeding point above the opened copper melting tank to put the copper coil into the copper melting tank;

[0048] S4, close the cover;

[0049] The remote control system is used to control the crane hoist to move to the top of the adjacent copper melting tank to prevent the tank cover, lift the tank cover, move it to the top of the original copper melting tank, cover the tank cover on the original copper melting tank, and seal it.

[0050] The above remote control system intelligently controls the movement of the crane spreader by combining the preset points of the target point position in the operation area with the on-site process. The crane spreader is a high-precision gantry crane equipment. The control and operation accuracy of the trolley, car and spreader is within ±2cm, which improves the intelligent control accuracy and operation efficiency.

[0051] The reserve rack is a structure for storing copper coils. The copper coils are placed on the reserve rack in advance, and the position of each copper coil is calibrated. A photoelectric sensor is set at the position corresponding to each copper coil on the reserve rack to detect the status of the copper coils on the reserve rack in real time and transmit signals to the remote control system. The remote control system determines and controls the crane to move to the reserve rack with copper coils to pick up the materials.

[0052] The laser rangefinder on the crane detects the real-time position of the crane, collects the position coordinates of the large and small vehicles and the spreader in real time, and automatically plans the path according to the starting position of the operation and the real-time positions of the large and small vehicles and the spreader to automatically run to the destination position and automatically execute control actions to lift the can lid, copper coil and automatically feed materials, etc.

[0053] The copper dissolving tank is fed with materials through remote automatic control to avoid the copper wire breaking and injuring people during the feeding process, thereby reducing environmental pollution and health risks to operators.

[0054] In another embodiment, the remote control system can also intervene in the emergency stop button and alarm system to ensure that the power can be quickly cut off in an emergency to ensure the personal safety of the operators. At the same time, a personnel identification system can be added to monitor the entire operation area and the driving operation in real time. If a person breaks in, the automatic control system will automatically pause the process and prompt the operator.

[0055] Use high-speed and accurate metering equipment to reduce waiting time during the feeding process, improve production efficiency, optimize the feeding process, reduce unnecessary operation links, reduce production costs, and plan production plans and material requirements in advance through data analysis and prediction to ensure the continuity and stability of the production process.

[0056] In a further specific embodiment, in said S1;

[0057] An XYZ space coordinate system is established with the initial position of the crane as the center point, and the position coordinates of the reserve rack (x1, y1, z1), the position coordinates of the copper coil (x2, y2, z2), the position coordinates of the copper melting tank cover (x3, y3, z3), and the position coordinates of the copper melting tank feeding point (x4, y4, z4) are calibrated in the XYZ coordinate system;

[0058] All coordinates involved in the operation process are imported into the remote control system, and then the automation control system executes the automatic process and controls the driving action according to the set position coordinates.

[0059] Among them, x1, x2, x3, x4 represent the left and right moving distance of the crane trolley; y1, y2, y3, y4 represent the forward and backward moving distance of the crane trolley; z1, z2, z3, z4 represent the moving distance of the crane trolley action;

[0060] Real-time position collection during the operation of the crane is carried out using laser distance measurement. Laser distance meters are installed on the trolley, crane and spreader sides to collect the left and right distance of the trolley (X), the front and rear movement distance of the trolley (Y), and the height distance of the spreader (Z) in real time.

[0061] In said S2;

[0062] The remote control system controls the crane to move according to the position coordinates (x3, y3) of the copper melting tank cover. At the same time, the laser rangefinder installed on the crane detects the distance moved by the crane in real time to determine whether the crane reaches the coordinate position. After reaching the coordinate position, the laser rangefinder sends a stop command.

[0063] Then the remote control system controls the action of the hoist, and the hoist moves to z3 to complete the hoisting of the tank cover, and detects the (x3, y3, z3) coordinates of the adjacent copper melting tank cover, repeats the above action, and stacks the tank cover of the original copper melting tank on the adjacent copper melting tank cover, waiting for the next instruction.

[0064] In said S3;

[0065] The remote control system controls the crane to move according to the position coordinates (x1, y1) of the reserve rack. At the same time, the laser rangefinder installed on the crane detects the distance moved by the crane in real time to determine whether the crane reaches the coordinate position. After reaching the coordinate position, the laser rangefinder sends a stop command.

[0066] Then the remote control system controls the crane to move according to the position coordinates (x2, y2) of the copper coil. At the same time, the laser rangefinder set on the crane measures the distance moved by the crane in real time to determine whether the crane has reached the coordinate position. After reaching the coordinate position, the laser rangefinder sends a stop command.

[0067] Finally, the remote control system controls the hoist to move according to the z2 of the copper coil, moves to z2, completes the lifting of the copper coil, then retracts the hoist, controls the hoist to return to the original copper melting tank position coordinates (x3, y3), and then controls the crane hoist to move according to the position coordinates (x4, y4) of the feeding point. After reaching the coordinate position, the laser rangefinder sends a stop command, and the remote control system controls the hoist to move with the copper coil to the feeding point of the z4 coordinate to complete the feeding action.

[0068] In S4;

[0069] The remote control system controls the crane to move according to the position coordinates (x3, y3) of the copper melting tank cover where the tank covers are stacked. At the same time, the laser rangefinder set on the crane detects the distance moved by the crane in real time to determine whether the crane reaches the coordinate position. After reaching the coordinate position, the laser rangefinder sends a stop command.

[0070] Then the remote control system controls the action of the hoist, and the hoist moves to z3 to complete the hoisting of the original tank cover, and hoists the tank cover to the original copper melting tank and closes the cover to seal it.

[0071] In the above process, the crane control is mainly divided into three parts: the trolley, the car, and the spreader. The automatic control system performs automatic operations based on the calibrated coordinate point values ​​and processes, and controls the crane, the trolley, and the spreader to control and operate the three parts simultaneously to improve the timeliness of the entire process.

[0072] In S1, a circle is drawn with the center of the mouth plane of the copper melting tank as the midpoint and the outer diameter of the copper coil as the calibrated diameter, as the first feeding point;

[0073] Then, the second feeding point, the third feeding point, the fourth feeding point, the fifth feeding point, the sixth feeding point, the seventh feeding point, the eighth feeding point and the ninth feeding point of the same size are arranged counterclockwise around the first feeding point, and the angle between two adjacent feeding points is 45°.

[0074] The mouth plane of the copper melting tank is used as the calibration position of the feeding point. Taking the circular mouth of the tank as an example, 9 calibration points are calibrated on the mouth of the tank. According to the difference in copper dissolving rate at different positions inside the tank, feeding is carried out at the corresponding calibration points, and the 9 calibration points cover the entire mouth of the tank as much as possible to ensure the reaction rate inside the tank and the uniformity of the reaction at each position.

[0075] The calibration point at the center of the tank mouth is the first feeding point, and the second feeding point, third feeding point, fourth feeding point, fifth feeding point, sixth feeding point, seventh feeding point, eighth feeding point and ninth feeding point are set on its surrounding side. The remaining eight calibration points are distributed in a circular array at the tank mouth, and the angle between two adjacent calibration points is 45°.

[0076] The above specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0077] The technical features of the above embodiments may be arbitrarily combined (as long as there is no contradiction in the combination of these technical features). To make the description concise, not all possible combinations of the technical features in the above embodiments are described; these embodiments that are not explicitly written should also be considered to be within the scope of this specification.

[0078] The present invention is described in more detail through general description and specific embodiments. It should be noted that, without departing from the concept of the present invention, it is obvious that several variations and improvements can be made to these specific embodiments, which all belong to the protection scope of this application. Therefore, the protection scope of the patent of this application shall be subject to the attached claims.
