[0031] Example 1

[0032] See also Figure 1 and Figure 2 The present invention is an automatic tool changing device for a lithium-ion battery diaphragm finished product slitting machine, comprising a control system 1, a tool detection system 2, a tool storage system 3 and a tool changing system 4. The tool detection system 2 is used to monitor tool status data in real time and feed it back to the control system 1. The control system 1 is used to determine whether tool replacement or maintenance is required based on the monitored tool status data. When the control system 1 sends a tool changing instruction to the tool storage system 3 and the tool changing system 4, the tool storage system 3 is used to store and manage different types of tools. The tool changing system 4 obtains a new tool from the tool storage system 3 and performs a tool changing action.

[0033] During the use of the automatic tool changing device of the present application, the real-time status of the tool is monitored by the tool detection system 2 to obtain the real-time monitoring tool status data. The control system 1 determines whether it exceeds the preset threshold value based on the real-time monitoring tool status data. When it exceeds the preset threshold value, it means that the wear and damage of the real-time monitoring tool is serious and the tool needs to be replaced or repaired. The control system 1 instructs the tool changing system 4 to replace the tool. The tool changing system 4 performs the tool changing action according to the instruction of the control system 1 and obtains the new tool from the tool storage system 3. The operation is convenient, so that the present application can realize the automatic tool changing of the lithium-ion battery diaphragm slitting machine, improve the production efficiency and tool changing accuracy, and reduce labor costs and safety risks; the tool storage system 3 in the present application can realize the automatic management of the tool, improve the utilization rate and management efficiency of the tool; the tool detection system 2 in the present application can monitor the status of the tool in real time, and send out the tool changing signal in time to ensure the slitting quality and production efficiency; the control system 1 in the present application adopts advanced automatic control technology, which can realize the functions of automatic tool changing, tool management and fault diagnosis, and improve the reliability and stability of the equipment.

[0034] In this specific embodiment, the tool detection system 2 includes a laser sensor and a pressure sensor, both of which are used to monitor the tool status data in real time; the laser sensor is specifically implemented as follows: the laser sensor can emit a laser beam to the tool surface and receive the reflected laser signal. By analyzing the changes in the reflected signal, the defects (such as cracks, wear, etc.) on the tool surface can be judged, so that the real-time monitoring tool status data obtained by the laser sensor is the defect and wear data on the tool surface. When the defect and wear data on the tool surface reaches the threshold value preset by the control system 1, the control system 1 issues a tool change command; the laser sensor is specifically implemented as follows: the pressure sensor is installed on the machine tool or the tool to monitor the cutting force in the cutting process in real time, so that the real-time monitoring tool status data obtained by the pressure sensor is the cutting force data in the tool cutting process. When the cutting force data in the tool cutting process exceeds the threshold value preset by the control system 1, the control system 1 issues a tool change command.

[0035] In this specific embodiment, the tool storage system 3 includes a plurality of RFID-identified drawer-type storage locations, each of which is used to identify and locate the corresponding tool; when the tool needs to be taken out or put in, the tool storage system 3 is used to automatically control the opening and closing of the RFID-identified drawer-type storage location; the process of automatically identifying tool specifications and accurately identifying and locating tools using a plurality of RFID-identified drawer-type storage locations involves multiple aspects such as RFID technology foundation, drawer-type storage location design, tool identification and positioning, and automatic control; the RFID technology foundation is to automatically identify the target object and obtain relevant data through radio frequency signals, and the RFID system is usually composed of electronic tags (also The design of the drawer-type storage position is to install an RFID tag on each tool. The tag stores key information such as the tool specifications, number, and service life. The RFID reader and antenna are installed at appropriate locations of the drawer-type storage position to ensure that all storage positions can be covered. The tool identification and positioning design is that when the tool is placed in the drawer-type storage position, the RFID reader sends a radio frequency signal through the antenna to activate the RFID tag on the tool and read its internal information. The system automatically identifies the specifications and numbers of the tool based on the read information. The automatic control design is to realize the automatic identification and positioning of the tool through the integrated automatic control system 1. When the tool needs to be taken out or put in, the system can automatically control the opening and closing of the drawer, as well as the identification and positioning process of the tool.

[0036] In this specific embodiment, the tool changing system 4 is a tool changing robot, which includes a robotic arm composed of a linear guide rail and a servo motor and a customized fixture, so that the tool changing robot is used to perform tool changing actions such as disassembly, replacement and reinstallation; the tool changing robot design structure can meet the tool disassembly and assembly requirements on the slitting machine, and the operation is quick and convenient.

[0037] In this specific embodiment, the control system 1 is a PLC control cabinet, which is connected to the tool detection system 2 through an interface circuit or a communication protocol, and is connected to the tool storage system 3 through a communication interface, and is connected to the tool changing system 4 through a communication interface or an electrical connection; the automatic tool changing device of the present application controls the system 1, the tool detection system 2, the tool storage system 3 and the tool changing system 4 through a layout design, so as to ensure the automation and efficiency of the mechanical processing process through a close control connection relationship. This connection relationship not only improves the processing efficiency and quality, but also reduces manual intervention and error rate.

[0038] Example 2

[0039] Combination Figure 1 and Figure 2 As shown, the present invention also provides an automatic tool changing method for a lithium-ion battery diaphragm finished product slitting machine, comprising the following steps:

[0040] S1. Control system 1 receives processing tasks and tool requirement information.

[0041] S2. Based on the tool demand information, the control system 1 instructs the tool storage system 3 to select and provide the required tools.

[0042] S3. The tool detection system 2 monitors the tool status data in real time and feeds back the data to the control system 1. The real-time monitored tool status data includes the defects and wear data on the tool surface and the cutting force data during the tool cutting process.

[0043] S4. When the real-time monitoring tool status data exceeds a preset threshold, the control system 1 instructs the tool changing system 4 to change the tool.

[0044] S5 . The tool changing system 4 executes the tool changing action according to the instruction of the control system 1 , and obtains a new tool from the tool storage system 3 .

[0045] S6. After the tool change is completed, the tool change system 4 feeds back the tool change success information to the control system 1, and detects and calibrates the new tool through the control system 1. After the processing task requirements are met, the processing task continues to be executed.

[0046] During the use of the automatic tool changing method of the present application, the real-time status of the tool is monitored by the tool detection system 2 to facilitate the acquisition of real-time monitoring tool status data. The control system 1 determines whether it exceeds a preset threshold based on the real-time monitoring tool status data. When it exceeds the preset threshold, it means that the wear and breakage of the real-time monitoring tool is relatively serious and the tool needs to be replaced or repaired. The control system 1 instructs the tool changing system 4 to replace the tool. The tool changing system 4 executes the tool changing action according to the instruction of the control system 1 and obtains a new tool from the tool storage system 3, which is easy to operate.
