Description

Technical Field

[0001] This utility model relates to the field of die-cutting equipment technology, specifically to a tool changing system for a die-cutting machine and a die-cutting machine including the system. Background Technology

[0002] Die-cutting machines are key equipment used in industries such as packaging, printing, and electronics for precision die-cutting of materials. In production practice, due to the diversification of product orders, it is often necessary to change different models of dies to adapt to different product specifications.

[0003] Currently, most die-cutting machines require a complete shutdown when changing the die. Operators must manually perform a series of operations, including disassembling the old die, installing the new die, and calibrating the positioning. This process is typically time-consuming, taking approximately 20 minutes to half an hour, resulting in frequent unplanned downtime. This not only severely reduces the overall equipment utilization rate (OEE) but also affects the continuity of the production line and overall production efficiency. This inherent defect of traditional die-cutting machines is particularly prominent in flexible production scenarios involving multiple product types and small batches, especially in the die-cutting of lithium-ion battery electrodes. Due to rapid product model iterations and extremely high production rhythm requirements, frequent downtime for die changes has become a key bottleneck restricting capacity and cost.

[0004] During the research process of this utility model, the inventors discovered that the drawback of the prior art is that the fixing, replacement and debugging of the die-cutting station must be carried out online. Summary of the Invention

[0005] One objective of this invention is to provide a tool changing system for a die-cutting machine and a die-cutting machine incorporating this system. Applying this solution helps avoid unplanned downtime caused by tool changing, improving overall equipment efficiency and production continuity. It is particularly suitable for processing fields requiring efficient and precise continuous die-cutting, such as lithium-ion battery electrode sheets.

[0006] In a first aspect, the present invention provides a blade changing system for a die-cutting machine, comprising: System rack; Control system; The tool holder carrier is movably mounted on the system frame; Two die-cutting stations, each located on the die holder carrier, are used to install the die-cutting molds. One of the two die-cutting stations serves as a production station within the die-cutting area, while the other serves as a preparatory station outside the die-cutting area. Under the control of the control system, the tool holder carrier can drive the two die-cutting stations to exchange positions, so that the preparatory station outside the die-cutting area enters the die-cutting area to become a production station, and the production station inside the die-cutting area moves out of the die-cutting area to become a preparatory station.

[0007] Optionally, it also includes an offline debugging station. When the preparation station is outside the die-cutting area, the offline debugging platform is located directly below the die on the preparation station and is used for the installation and calibration of the die.

[0008] Optionally, the offline debugging station is located outside the die-cutting area.

[0009] Optionally, the tool holder carrier is rotatably connected to the frame via a pivot.

[0010] Optionally, the tool holder carrier is slidably connected to the frame via a slide rail mechanism.

[0011] Optionally, the two die-cutting stations are arranged symmetrically about the motion center of the die holder carrier.

[0012] Optionally, both die-cutting stations are equipped with quick-change interfaces for rapid die installation.

[0013] Optionally, it also includes a synchronization control module. The synchronization control module is connected to the control system signal and is configured to drive the two die-cutting stations on the die holder carrier to exchange positions during the interval of the die-cutting material conveyor belt.

[0014] Optionally, the synchronization control module is connected to the material tension sensor and the die stroke sensor of the die-cutting machine.

[0015] Secondly, the present invention provides a die-cutting machine comprising: Mainframe rack; An unwinding mechanism, a die-cutting area, and a rewinding mechanism are sequentially arranged along the main frame, with the unwinding mechanism, die-cutting area, and rewinding mechanism arranged along the conveying path of the die-cutting material; The blade changing system for the die-cutting machine described above is installed on the main frame at a position corresponding to the die-cutting area; The production station of the tool changing system is located within the die-cutting area, while the preparation station is located outside the die-cutting area.

[0016] As can be seen from the above, during normal production, the die-cutting dies at the production stations within the die-cutting area perform continuous die-cutting operations. When a die replacement is required, the control system issues a command to drive the die holder carrier to move through its movable connection mechanism: causing the first die-cutting station and the second die-cutting station to exchange their positions relative to the die-cutting area. Specifically, the preparatory station for the new die, which was originally outside the die-cutting area and has been installed and calibrated, is moved into the die-cutting area and immediately becomes the new production station; simultaneously, the production station originally within the die-cutting area, which has the old die, is moved out of the die-cutting area and becomes the new preparatory station. The entire exchange process is completed in a very short time.

[0017] As can be seen, the tool changing system in this embodiment changes the traditional die-cutting machine's operation mode, which requires the machine to be stopped before the die can be changed. This embodiment's system constructs a dynamic tool holder carrier with two interchangeable workstations. One of the two die-cutting workstations on this carrier is located in the production workstation within the die-cutting area, keeping its die in an online production state. The other workstation is located in a preparation workstation outside the die-cutting area, keeping its pre-installed die in an offline preparation state. This allows the system to achieve parallel operation of the tool changing action and the production process on the timeline. Attached Figure Description

[0026] See Figures 1-5 .

[0027] This embodiment provides a tool changing system 74 for a die-cutting machine. The system mainly includes a system frame 1, a control system 4, a tool holder carrier 2, and two die-cutting stations (hereinafter referred to as the first die-cutting station 21 and the second die-cutting station 22, respectively).

[0028] The system frame 1 serves as the supporting foundation for the entire system. The tool holder carrier 2 is movably mounted on the system frame 1 via a movable connection mechanism (in this embodiment, it is a universal mechanical interface that allows the tool holder carrier 2 to change position). The first die-cutting station 21 and the second die-cutting station 22 are fixedly disposed on the tool holder carrier 2, and each station has a functional structure for installing and fixing the die-cutting.

[0029] The roles and positions of the first die-cutting station 21 and the second die-cutting station 22 are dynamically defined: one is configured and positioned as a production station within the die-cutting area 76, and the other is configured and positioned as a preparatory station outside the die-cutting area 76. The die-cutting area 76 refers to the fixed workspace on the die-cutting machine where the die and anvil cooperate to perform the die-cutting action.

[0030] The working principle of the tool changing system 74 is as follows: During normal production, the die-cutting dies at the production stations within the die-cutting area 76 perform continuous die-cutting operations. When a die-cutting die needs to be replaced, the control system 4 issues a command to drive the tool holder carrier 2 to move through its movable connection mechanism: causing the first die-cutting station 21 and the second die-cutting station 22 to exchange their positions relative to the die-cutting area 76. Specifically, the new die-cutting die preparation station (e.g., the second die-cutting station 22), which was originally located outside the die-cutting area 76 and had been installed and calibrated, is moved into the die-cutting area 76 and immediately becomes the new production station; at the same time, the production station (e.g., the first die-cutting station 21), which was originally located within the die-cutting area 76 and had the old die on it, is moved out of the die-cutting area 76 and becomes the new preparation station. The entire exchange process is completed in a very short time.

[0031] When this system is applied to lithium-ion battery electrode die-cutting machines, its workflow perfectly meets the extremely high requirements for continuity in electrode production. The electrode rolls continuously move along the conveyor belt, and the system does not need to stop when switching from one electrode type (corresponding to one die) to another. The new die at the preparatory station (e.g., the second die station 22) has already been installed and adjusted offline, and during a brief interval in the material conveyor belt, the station rapidly switches to the working position, seamlessly connecting the old and new production tasks.

[0032] The beneficial effect of this embodiment is that the tool changing system 74 changes the traditional die-cutting machine's operation mode, which requires the machine to be stopped before the die can be changed. This embodiment's system constructs a dynamic tool holder carrier 2 with two interchangeable workstations. One of the two die-cutting workstations on the tool holder carrier 2 is located within the die-cutting area 76, where the die is in an online production state. The other is located in a preparation workstation outside the die-cutting area 76, where the pre-installed die is in an offline preparation state. This allows the system to achieve parallel operation of the tool changing action and the production process on the timeline.

[0033] As an illustration of this embodiment, this preferred embodiment further includes an offline debugging platform, which is fixedly positioned outside the die-cutting area 76. The preparation station on the die holder carrier 2 is located outside the die-cutting area 76, and the offline debugging platform is located directly below the die installed on the preparation station, forming a vertical alignment relationship with it. The offline debugging platform provides a stable reference platform, and its platform height, parallelism, etc., can be finely adjusted.

[0034] The working principle of the offline debugging station is as follows: As an independent device, the offline debugging station has no mechanical linkage with the movable tool holder carrier 2, but it corresponds strictly in spatial position to the tool changing system 74. When the preparatory station, carrying the newly installed die, rotates or slides to a preparatory position outside the die-cutting area 76, the operator can use the offline debugging station to calmly and safely install and secure the new die, and perform fine calibration of cutting depth, pressure, and flatness based on the benchmark provided by the debugging station. All debugging work is completed simultaneously with the production line running at full speed and the production station performing normal die-cutting. Once the tool changing command is triggered, this preparatory station, which has reached the working state, can be immediately put into use. For specific installation and debugging techniques, please refer to existing technologies.

[0035] In electrode die-cutting applications, the precision requirements for electrode dies are extremely high. Cutting burrs and dimensional errors directly affect battery performance and safety. Setting up this offline testing station provides technicians with ample time and an environment for high-precision calibration, avoiding the haste and dangers of online debugging, and ensuring that the processing quality of the new die immediately meets the process standards after each die change.

[0036] The addition of this offline debugging station completely separates the pre-installation and pre-debugging processes of the die-changing molds from the busy production flow, achieving true offline preparation. This not only significantly improves the quality and safety of the tool change preparation operation, but also ensures that the production station operations are completely undisturbed, truly achieving complete parallelism between production and tool change preparation, pushing equipment utilization to its theoretical limit.

[0037] As an illustration of this embodiment, this embodiment also provides a specific mounting structure for the tool holder carrier 2: The tool holder carrier 2 is rotatably connected to the system frame 1 via a vertical rotating shaft, thus forming a rotating tool holder. The first die-cutting station 21 and the second die-cutting station 22 are symmetrically arranged at both ends of the rotating tool holder with the rotating shaft as the center. Its working principle is as follows: during tool changing, the control system 4 drives the rotating tool holder to rotate 180 degrees around the rotating shaft, thereby swapping the positions of the two stations. This method features a compact structure and rapid operation. The rotating tool holder allows the first die-cutting station 21 and the second die-cutting station 22 to alternately enter and exit the die-cutting area 76 with a compact arc trajectory through rotation around the rotating shaft, thus achieving seamless station switching with almost no increase in the overall equipment footprint. Specifically, based on the disclosure herein, the installation implementation of the rotating shaft can be found in existing technologies.

[0038] Alternatively, the tool holder carrier 2 can be slidably connected to the system frame 1 via a slide rail mechanism, thus forming a linearly moving tool holder. The first die-cutting station 21 and the second die-cutting station 22 are arranged side by side along the slide rail direction. Its working principle is as follows: during tool changing, the control system 4 drives the tool holder carrier 2 to move linearly along the slide rail by one station interval, causing the preparatory station to slide into the die-cutting area 76, while the production station slides out to the preparatory station. The slide rail mechanism can be implemented using existing technology.

[0039] Both of the above-mentioned blade holder carrier 2 mounting structures are applicable to electrode die-cutting machines. Among them, the rotary type is suitable for vertical die-cutting machines with limited space, and its movement is like the hands of a clock; the translational type is more suitable for the long and narrow layout of horizontal die-cutting machines, and the switching process is smooth.

[0040] As an illustration of this embodiment, quick-change interfaces 3 can be integrated into both the first die-cutting station 21 and the second die-cutting station 22. These interfaces typically include a pneumatic or hydraulic locking mechanism, standardized positioning pins and slots, and necessary electrical or pneumatic quick connectors. The operator simply pushes the die into the interface and triggers the locking mechanism to complete the physical installation and media connection, reducing the time for traditionally cumbersome bolt tightening and pipeline connection from several minutes to tens of seconds. These quick-change interfaces can be, but are not limited to, existing die-cutting installation interfaces.

[0041] As an illustration of this embodiment, the tool changing system 74 further includes a synchronization control module 5, which is signal-connected to the control system 4. The synchronization control module 4 collects in real time the encoded signal from the material feed encoder 61 of the die-cutting machine itself, the tension sensing signal from the material tension sensor 62, and the position signal from the die stroke sensor 63. The control logic within the synchronization control module 5 analyzes these signals to determine the safe interval during the die-cutting material's conveyor belt operation, where the die is raised, the material is stationary, or the tension is minimal. Then, within this interval window, it sends a high-speed switching command to the drive mechanism of the tool holder carrier 2, driving the first die station 21 and the second die station 22 on the tool holder carrier 2 to exchange positions, achieving rapid online tool changing.

[0042] Preferably, the first die-cutting station 21 and the second die-cutting station 22 are arranged symmetrically with respect to the motion center (rotating shaft or slide rail center) of the tool holder carrier 2. This ensures that the center of gravity of the tool holder carrier 2 is stable and the inertial torque is small during movement, thereby enabling faster and smoother switching, and also facilitating the accurate calibration of the control system 4.

[0043] When applied to electrode die cutting, the quick-change interface 3 greatly reduces the labor intensity and skill requirements of operators; the synchronous control module 5 ensures that the die switching action is synchronized with the material movement during the high-speed, continuous conveyor belt movement of the electrode material, avoiding pulling or collision on the fragile electrode; and the symmetrical layout ensures the stability of the equipment under high-speed switching.

[0044] This embodiment provides a die-cutting machine including the aforementioned tool changing system 74. This die-cutting machine is designed for continuous and efficient die-cutting operations and is particularly suitable for processing precision materials such as lithium-ion battery electrodes.

[0045] like Figure 1 , 2 It is shown that, in Figure 1 In the middle, the die carrier has two die-cutting stations, each equipped with a die, which are positioned opposite each other on the same horizontal plane, forming the same orthographic projection. Figure 2 The die carrier and the two dies on it are covered under the top plate of the die-cutting equipment, which provides dust protection and improves the protection of the dies.

[0046] It mainly includes a main frame 71, an unwinding mechanism 7, a die-cutting area 76, a winding mechanism 73, and a tool changing system 74 integrated thereon. Among them, the main frame 71, as the main load-bearing body of the entire equipment, is usually a rigid frame structure welded from steel profiles, providing installation reference and support for all functional components.

[0047] The unwinding mechanism 7 is installed at the feed end of the main frame 71. It includes an unwinding shaft for carrying the raw material roll, a magnetic powder brake or servo tension control system for providing constant back tension, and a guide device for correction. Its function is to continuously, smoothly, and accurately unwind the die-cut material (such as electrode roll) and feed it into the subsequent station.

[0048] The die-cutting area 76 is located in the middle of the main frame 71 and is the core functional area for performing die-cutting processing. An anvil or lower die table 75 is fixedly installed in this area. The tool holder carrier 2 of the tool changing system 74 in this embodiment (whether rotary or translational) is installed in this area, enabling its production station to move precisely to the area directly opposite to this region. When the die on the production station moves downward under the action of the drive device, it cooperates with the fixed anvil to complete the cutting of the die-cutting material passing through it. Therefore, the die-cutting area 76 can also be defined as the space where the die and the anvil interact.

[0049] The winding mechanism 73 is installed at the discharge end of the main frame 71. It includes a winding shaft driven by a motor and a tension detection and control system 4 that provides constant front tension. It is used to rewind the finished material (or together with waste material) after die-cutting into rolls to maintain the continuous operation of the production line.

[0050] During operation, the unwinding mechanism 7, the die-cutting area 76, and the rewinding mechanism 73 are arranged sequentially along the material conveying path, forming a continuous processing line. The material is drawn out from the unwinding mechanism 7 and passes horizontally (or along a set path) through the die-cutting area 76 under tension control. After being processed in the die-cutting area 76, the finished product is wound up by the rewinding mechanism 73. The entire path is supported and guided by a series of guide rollers.

[0051] In the die-cutting equipment, the system frame 1 of the tool changing system 74 can, but is not limited to, be a separate module, securely mounted on the main frame 71 at the position corresponding to the top of the die-cutting area 76 via bolt connections, positioning pins, or other means. This allows the production station of the tool changing system 74 to be precisely located in the working position of the die within the die-cutting area 76; while its preparation station is naturally located to the side or rear of the die-cutting area 76, in a space convenient for setting up an offline debugging station and for personnel operation.

[0052] The synchronous control module 5 of the tool changing system 74 can be, but is not limited to, integrated into the main control cabinet 77 of the die-cutting machine, and receives signals from unwinding / rewinding tension sensors, material encoders, etc., thereby achieving synchronization with the production cycle of the whole machine.

[0053] In electrode die-cutting production, the electrode material runs continuously along the aforementioned conveying path. When a product model needs to be changed, the operator completes the setup and adjustment of the new die on the offline debugging table below the preparatory station (located outside the die-cutting area 76). When the time for die changing is reached, the die-changing system 74 completes the station switch instantaneously with the material conveyor belt. The new die is immediately put into production in the die-cutting area 76, while the replaced die moves with the workpiece to outside the die-cutting area 76 to await maintenance. The unwinding and rewinding mechanism 73 operates continuously throughout the process, and may only undergo speed matching adjustments when product specifications are changed, but never stops due to die changing.

[0054] As can be seen from the above, this embodiment integrates the dual-station flying tool changer system 74 into the continuous workflow of a traditional die-cutting machine, upgrading the die-cutting area 76 from a fixed station to an intelligent station that can dynamically switch dies. It not only retains all the mature and reliable conveying and tension control functions of traditional die-cutting machines, but also overcomes the efficiency bottleneck of existing production processes—machine stoppage during tool changes, thus forming a brand-new advanced die-cutting equipment suitable for flexible and high-efficiency production.

[0055] Based on the above system architecture, the complete workflow for non-stop tool changing includes: (1) Preparation stage: When the preparation station (such as the second die-cutting station 22) is outside the die-cutting area 76, the operator completes the installation and precise calibration of the die required for the next production task on the offline debugging platform directly opposite it.

[0056] (2) Production monitoring stage: The production station (such as the first die-cutting station 21) in the die-cutting area 76 continues to perform die-cutting operations; at the same time, the control system 4 and the synchronous control module 5 monitor the production status and material conveyor cycle in real time.

[0057] (3) Flight switching stage: When a tool change is required, the system drives the tool holder carrier 2 (rotation or translation) to move quickly during the interval of the die-cutting material conveyor belt, so that the prepared work station enters the die-cutting area 76 to become a new production work station, while moving the original production work station out.

[0058] (4) Subsequent processing and cycle stage: The station removed from the die-cutting area 76 becomes a new standby station. The operator can remove the old die-cutting die, perform cleaning and maintenance, and prepare the die-cutting die for the next time. At this point, the system is ready for the next die change, and the cycle repeats.

[0059] To further demonstrate the effectiveness of the system in this embodiment, we conducted the following comparative tests. The tests were carried out on the same commercial die-cutting machine used for lithium-ion battery electrode production. By replacing its original fixed blade holder with the blade changing system 74 of this invention (integrating all features of the third preferred embodiment), and under the same product production task (involving frequent model changes), the key performance indicators of the two working modes were recorded and analyzed respectively.

[0060] 1. Test subject: The same lithium-ion battery electrode die-cutting machine, only the blade holder system was changed.

[0061] Second, comparison mode: Traditional mode: The original machine is used to fix a single station tool holder. Tool changing requires the entire line to be shut down for online disassembly, installation and debugging.

[0062] In this embodiment, the tool changing system 74 is activated, ensuring uninterrupted production during tool changing, as the new die has already been prepared on the offline debugging platform.

[0063] Third, the test task: simulate the task scenario of switching between production of different types of electrode sheets multiple times within a single production shift in actual production.

[0064] Fourth, data acquisition: Use equipment timers, production counters and quality testing instruments to measure and record the following indicators.

[0065] The test results are compared below: The tool changing system 74 and die-cutting machine of this utility model, through the structure of the double-die station, can perform offline preparation and synchronous die station position exchange. When applied to the die-cutting machine, it avoids production downtime caused by tool changing, and transforms the tool changing operation from a bottleneck in the production process to an offline process that can be synchronized with the production line. While ensuring processing quality, it brings efficiency improvement to high-efficiency and flexible production, especially in high-end fields such as lithium-ion battery manufacturing.

[0066] The above embodiments do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
