DETAILED DESCRIPTION

[0016] The application will be described in detail below with reference to the drawings.

[0017] As Figures 1 to 6 shown, a copper foil cutting and punching coordination device comprises: A continuous feeding device 1 is used for feeding copper foil coiled material at a uniform speed and keeping the copper foil tensioned, the continuous feeding device 1 comprises a copper foil conveying frame 11, a feeding shaft 12, four conveying rollers 13 and an accumulator assembly 14, the copper foil conveying frame 11 can provide a stable copper foil feeding path to ensure the stable conveying of the copper foil. The feeding shaft 12 is installed at the front end of the conveying frame, the feeding shaft 12 releases the copper foil coiled material at a uniform speed under the driving of a motor, the four conveying rollers 13 are uniformly distributed on the copper foil conveying frame 11 and have the same structure and working principle, which ensures the stable feeding of the copper foil, and the accumulator assembly 14 is arranged at the connecting position of the continuous feeding device 1 and the copper foil punching device 2, which forms a buffer section during the conveying of the copper foil; As Figure 2 and Figure 3 shown, the accumulator assembly 14 can form a buffer section during the conveying of the copper foil to avoid the situation that there is too much or too little copper foil due to the different time synchronization in the punching and cutting process. The accumulator assembly 14 comprises a roller shaft 141 which is arranged transversely and has two ends connected with limiting sleeves 142, the two ends of the roller shaft 141 are respectively connected with sliding blocks 143, the sliding blocks 143 are sleeved on vertical guide rods 144 and can slide up and down along the vertical guide rods 144, the sliding stroke is within 450 mm, and the up and down floating of the roller shaft 141 is used for forming a storage buffer section during the conveying of the copper foil.

[0018] More specifically, the roller shaft 141 is floated up and down by its own weight, and the floating of the roller shaft 141 is driven by the conveying process of the copper foil. When the copper foil is pulled, the roller shaft 141 rises; when the copper foil is discharged, the roller shaft 141 descends, forming a buffer section. Through the up and down floating of the roller shaft 141, the length of the storage section can be adjusted, so that the copper foil conveying process is more stable.

[0019] As shown in Figure 4 , the copper foil punching device 2 is used for punching the discharged copper foil, and the copper foil punching device 2 includes a main frame 21 supporting the entire punching system and keeping the fixed position of each component; the punching assembly 22 is installed in the middle of the main frame 21, and the punching assembly 22 uses a punching die to position and punch the copper foil, so as to ensure the position accuracy of the punching; the roller assembly has three, the inlet roller assembly 23 is installed at the copper foil input port of the punching device, the outlet roller assembly 24 is provided with two, and the structure and principle are the same, and the outlet roller assembly 24 is installed at the copper foil output port of the punching device, which is used for stable conveying of the copper foil and keeping the copper foil from being deformed in the punching process.

[0020] As shown in Figure 5 and Figure 6 , the cutting and pulling device 3 is used for pulling the punched copper foil to a certain length and cutting it, and the cutting and pulling device 3 includes a base 31, a feeding assembly 32, a pneumatic pressing assembly 33, a cutting assembly 34, a pulling assembly 35 and a pulling platform 36. The base 31 is used for supporting the entire cutting and pulling device 3, and the cutting assembly 34, the pulling assembly 35 and the pulling platform 36 are directly installed on the base 31.

[0021] The feeding assembly 32 is arranged in front of the cutting assembly 34 and is installed on the support seat 341 of the cutting assembly 34, which is used for receiving the punched copper foil and guiding it into the cutting area. The feeding assembly 32 includes a feeding roller 321, an ion wind curtain 322, a feeding bottom plate 323 and a bridge plate 324. The feeding roller 321 is used for receiving the punched copper foil. The ion wind curtain 322 is installed above the feeding roller 321 and is used for eliminating static electricity generated in the conveying process of the copper foil. The copper foil is fixed by the pneumatic pressing assembly 33 on the bridge plate 324 for cutting.

[0022] The pneumatic pressing assembly 33 is installed on the sliding blocks of the pneumatic slides on both sides of the feeding bottom plate 323, and the feeding bottom plate 323 is fixed on the support seat 341 of the cutting assembly 34 and can make linear reciprocating motion on the bridge plate 324 under the action of the pneumatic cylinder. In the cutting process, the remaining copper foil is pushed forward by a small distance, so that the remaining copper foil does not fall off from the conveying path and is always kept in a clippable position, and automatically resets after the pulling assembly 35 clamps the copper foil.

[0023] The cutting assembly 34 is responsible for cutting during the conveying process of the copper foil, and is installed on the base 31 through the support seats 341 on both sides. The material pulling assembly 35 is responsible for pulling copper foil from behind the cutting assembly 34 onto the material pulling platform 36. After being pulled to a preset length, it is cut by the cutting assembly 34 to form copper foil sheets of a certain size. Simultaneously, the material pulling assembly 35 can also transport the cut sheets to the suction position on the material pulling platform 36. The material pulling assembly 35 is a three-axis linkage mechanism capable of achieving a fully automatic material pulling process of "positioning-descent-clamping-movement-release-rise-reset". The bottom layer is a linear sliding mechanism 351, which uses a motor and coupling to directly drive the ball screw, converting rotational motion into precise linear motion, responsible for the precise positioning and rapid movement of the material pulling assembly 35 in the horizontal direction. The middle layer is a lifting mechanism, with a servo slide 353 mounted on a fixed lifting base 352. The slide is connected to a lifting plate 354, and the servo motor drives the lifting plate 354 to achieve the vertical linear movement of the end effector. The end gripping mechanism consists of three sets of pneumatic grippers 355, which are mounted side by side on a fixed rod 356. The fixed rod 356 is connected to a lifting plate 354, thereby realizing the lifting and lowering of the pneumatic grippers 355.

[0024] A collaborative control system controls the operating rhythm of the continuous feeding device 1, the copper foil punching device 2, and the cutting and pulling device 3, ensuring coordination and synchronization between each process and smooth transition between copper foil punching and cutting. The collaborative control system includes sensors for real-time detection of the copper foil's movement, specifically whether the copper foil has reached the punching and cutting positions and whether the pulling action has been completed. Sensor signals are fed back to the control system to adjust the operating rhythm of each device. Based on the signals provided by the sensors and set parameters, the system dynamically adjusts the operating rhythm of the copper foil feeding, punching, cutting, and pulling devices. The collaborative control system makes the copper foil flow process smoother, reduces jamming or accumulation, and improves overall production efficiency.

[0025] A method for coordinated control of copper foil cutting and punching includes the following steps: S1: The copper foil is fed at a constant speed by the continuous feeding device 1 under the drive of the motor. The feeding speed is 15m / min. The copper foil is fed to the storage component by the guide roller. After passing through the storage component 14, a buffer section is formed. The copper foil will consume the buffer section under the pulling action of the pulling component 35 and reach the copper foil punching device 2. S2: A photoelectric sensor is installed at the entrance of the copper foil punching device 2 to detect whether the copper foil has reached the preset punching position. The detection signal is fed back to the collaborative control system. When the system determines that the punching module has been reset and the safety conditions are met, it sends a punching signal to the copper foil punching device 2 to perform the copper foil punching operation. After the punching is completed, it sends a completion signal and stops the operation, waiting for the next section of copper foil to arrive. S3: The punching completion signal triggers the start of the cutting and pulling device. Under the combined traction of the feeding component 32 and the pneumatic pressing component 33, the copper foil reaches the clamping position of the pulling component 35. The pneumatic gripper 355 of the pulling component 35 clamps the copper foil and pulls it to the set length under the drive of the linear sliding mechanism 351. At the same time, the copper foil that has not been punched enters the punching area to prepare for the next punching. S4: When the collaborative control system receives the material pulling completion signal, it controls the pneumatic pressing component 33 to press down, fixing the copper foil on the bridge plate 324, and triggering the cutting component 34 to perform the cutting action. While the current copper foil is being cut and pulled, the next section of copper foil will begin the punching action after entering the punching area. After the next section of copper foil is punched, the pneumatic pressing component 33 will continue to push it forward a short distance, with a conveying range of 40mm, so that it enters the clamping area of ​​the material pulling component 35. After the material pulling component 35 successfully clamps it, the pneumatic pressing component 33 releases and resets.

[0026] S5: After the cutting is completed, the material pulling assembly 35 continues to transport the copper foil sheet to the suction station. Then, the material pulling assembly 35 is released and reset under the control of the collaborative control system. The compensation section of the material storage assembly 14 is released, and the copper foil returns to the starting position of the next cycle, thereby realizing continuous collaborative control of the feeding, punching, pulling and cutting processes.
