[0036] like Figure 1 , Figure 2 As shown, this utility model provides a battery aluminum foil flatness detection device for a slitting equipment, used to detect the flatness of battery aluminum foil, including an online plate shape detection device 1 and a battery aluminum foil slitting device 2;

[0037] The online plate shape detection device 1 is installed in the battery aluminum foil slitting device 2, and the online plate shape detection device 1 is arranged opposite to the battery aluminum foil conveyed to the battery aluminum foil slitting device 2;

[0038] The online plate shape detection device 1 is used to detect the flatness of battery aluminum foil.

[0039] This application provides a battery aluminum foil flatness detection device for slitting equipment, which realizes full-process monitoring of battery aluminum foil flatness. By setting the online plate shape detection device relative to the battery aluminum foil conveyed to the battery aluminum foil slitting device, the flatness of the battery aluminum foil during the slitting process can be detected in real time, and potential flatness problems can be detected and corrected in a timely manner, ensuring that the slitting battery aluminum foil has good flatness, thereby improving the accuracy and quality of battery aluminum foil slitting.

[0040] Specifically, the online plate shape detection device 1 includes a detection device 3 and a sliding track 4; the sliding track 4 extends along the width direction of the battery aluminum foil; the detection device 3 is slidably disposed on the sliding track 4.

[0041] In practical applications, a detection device 3 is installed on the sliding track 4, and the cooperation between the sliding track 4 and the detection device 3 is used to complete the flatness detection of the battery aluminum foil. The sliding track 4 allows the detection device 3 to move freely in the width direction of the battery aluminum foil, ensuring comprehensive detection of the entire width of the aluminum foil. This design not only improves the positional flexibility and detection accuracy of the online plate shape detection device 1, but also adapts to different detection needs, thus effectively solving the need for flatness detection during the battery aluminum foil cutting process.

[0042] Specifically, the detection device 3 is a force sensor.

[0043] In specific applications, the force sensor is used as the detection device 3, which can detect the internal stress of the battery aluminum foil in real time, and the flatness of the battery aluminum foil can be determined according to the detected internal stress. The force sensor can be, but is not limited to, a non-contact sensor such as an optical force sensor, an ultrasonic force sensor, a laser force sensor, a capacitive force sensor, an electromagnetic force sensor, or a fiber-optic force sensor. Through the force sensor, the deviation of the flatness can be found and corrected in time, and the quality of the battery aluminum foil product is improved. Among them, the optical force sensor, the ultrasonic force sensor, the laser force sensor, the capacitive force sensor, the electromagnetic force sensor, or the fiber-optic force sensor is a prior art, which will not be described in detail here.

[0044] In some optional embodiments, the detection device 3 can also be a distance sensor, which obtains the distance from each position of the battery aluminum foil to the detection device 3, so as to ensure the flatness of the battery aluminum foil by ensuring that the distance from each position of the battery aluminum foil to the detection device 3 is equal.

[0045] Specifically, the sliding rail 4 includes a sliding block 5 and a rail 6; the sliding block 5 is fixedly connected with the detection device 3; and the sliding block 5 is movably connected with the rail 6.

[0046] In specific applications, the sliding block 5 is fixedly connected with the detection device 3, which ensures that the detection device 3 will not displace during movement, thereby ensuring the accuracy of detection. The sliding block 5 is movably connected with the rail 6, so that the detection device 3 can slide on the rail 6, thereby enabling flatness detection of the battery aluminum foil at different positions.

[0047] The design of the sliding rail 4 fully considers the stability and adjustability of the detection device 3. By adjusting the material of the sliding block 5 and the structural design of the rail, the smoothness and durability of sliding can be further improved, for example, a material with low friction coefficient can be selected to reduce wear and tear. In addition, considering various special situations that may occur during detection, such as installing a limiting device on the rail 6 to prevent the sliding block 5 from sliding out of the rail, or setting anti-skid measures or lubricating pads on the rail 6 to reduce the risk of accidental sliding or reduce friction and wear, thereby improving the safety and reliability of the entire online plate-type detection device 1. Among them, the sliding block 5 and the rail 6 can be movably connected through common mechanical connection methods such as pulleys, guide rails, or electromagnetic methods, pneumatic methods, etc., so as to reduce friction and mechanical wear while ensuring flexible movement. In addition, positioning devices such as sensors can be added to the sliding block 5 as needed to monitor and adjust the position of the sliding block 5 in real time, thereby achieving precise positioning of the online plate-type detection device 1.

[0048] Specifically, the online plate-type detection device 1 further comprises a first motor;

[0049] The first motor is used to drive the movement of the sliding block 5 and adjust the movement speed of the sliding block 5.

[0050] In a specific application, a first motor is arranged in the online plate type detection device 1 to drive the movement of the sliding block 5 along the track 6, and the movement speed of the sliding block 5 is adjusted by changing the running speed of the first motor.

[0051] The first motor can be, but is not limited to, a servo motor or a stepper motor, to achieve high-precision control of the movement of the sliding block. Moreover, by arranging a corresponding control system, an operator can flexibly adjust the position and speed of the detection equipment 3 according to the detection requirements, thereby ensuring the accuracy of the detection process. The first motor can drive the sliding block 5 to move along the track 6 by screw transmission, gear transmission or other transmission structures, to achieve the position adjustment of the detection equipment 3.

[0052] Specifically, the battery aluminum foil slitting device 2 includes an unwinding machine 7, a slitting machine 8 and a winding machine 9.

[0053] The unwinding machine 7 is used to output the battery aluminum foil and provide tension for the battery aluminum foil.

[0054] The slitting machine 8 is used to slit the battery aluminum foil into small rolls of the required width.

[0055] The winding machine 9 is used to wind the slit battery aluminum foil into a roll shape.

[0056] In a specific application, the battery aluminum foil slitting device 2 is divided into three parts: the unwinding machine 7, the slitting machine 8 and the winding machine 9. The function of the unwinding machine 7 is to provide the required tension for the battery aluminum foil. The unwinding machine 7 is equipped with an advanced tension control system, which can accurately adjust the tension of the battery aluminum foil according to production needs. This not only prevents the battery aluminum foil from producing wrinkles or stretching deformation during unwinding, but also ensures the stability and accuracy of the battery aluminum foil in the subsequent slitting process. The slitting machine 8 is specially designed to process wide battery aluminum foil, and through precise cutting technology, it is divided into small rolls of the required size. The width of each small roll can be adjusted according to specific requirements to ensure adaptation to different application requirements. The winding machine 9 is responsible for neatly winding the slit aluminum foil rolls to ensure that they are neatly stacked for subsequent use. The battery aluminum foil slitting device 2 is equipped with an automatic control system, which can adjust the winding force and speed according to the characteristics of the aluminum foil and specific processing requirements to achieve the best winding effect.

[0057] The battery aluminum foil slitting device 2 can ensure high precision in the slitting process while avoiding material waste through the unwinding machine 7, the slitting machine 8 and the winding machine 9. In operation, the battery aluminum foil first passes through the unwinding machine 7, is given the required tension for production, then passes through the slitting machine 8, is cut into multiple small rolls that meet the needs of subsequent processing, and then passes through the winding machine 9 to wind these slit aluminum foils into a roll shape for transportation and storage.

[0058] Specifically, the winding machine 9 includes an upper winding machine and a lower winding machine.

[0059] In specific applications, the winding machine 9 includes an upper winding machine and a lower winding machine. The upper winding machine is located at an upper position inside the battery aluminum foil slitting device 2, and the configuration feature of the upper winding machine is that the finished product after winding is neat and convenient to take, which is suitable for scenes with higher requirements for product quality. Therefore, when the battery aluminum foil is being slit, it is necessary to ensure its flatness to ensure product quality and production efficiency, and the upper winding machine can perform well. The lower winding machine is located at a lower position inside the battery aluminum foil slitting device 2, and the configuration feature of the lower winding machine is that the winding of the material is convenient, which is suitable for occasions of mass production and repeatability. For example, if a large amount of winding work needs to be done quickly during production, the lower winding machine can effectively improve the efficiency and reduce the production time and labor cost.

[0060] Specifically, the slitting machine 8 includes a base frame, a transmission mechanism, and a cutting system.

[0061] The base frame is used to fix the position of the transmission mechanism and the cutting system.

[0062] The transmission mechanism is used to transport the battery aluminum foil.

[0063] The cutting system is used to slit the battery aluminum foil.

[0064] In specific applications, the slitting machine 8 includes a base frame, a transmission mechanism, and a cutting system. The base frame is used to fix the position of the transmission mechanism and the cutting system to ensure the stability of the equipment; the transmission mechanism is used to transport the battery aluminum foil to the cutting system, so as to ensure that the aluminum foil can be accurately and continuously sent to the cutting position. The cutting system is used to accurately slit the battery aluminum foil, and through reasonable design and configuration, it can ensure that the aluminum foil maintains good flatness after slitting, improving product quality and slitting efficiency. The stability of the base frame directly affects the operation accuracy of the entire equipment, and through firm design and installation, processing errors caused by equipment shaking or displacement can be avoided.

[0065] The transmission mechanism includes a plurality of rollers or conveyors, which transport the battery aluminum foil to the cutting system at a constant speed and in a stable manner through synchronous control. In order to further improve the accuracy of transmission, a tension adjusting device and a position correcting device can be added to the transmission path to ensure that the aluminum foil is always in the best state during transmission, avoiding deviation or relaxation.

[0066] The cutting system can realize accurate slitting operation by introducing high-precision cutting blades or laser cutting devices to ensure that each piece of aluminum foil after cutting has consistent width and edge quality. At the same time, an automatic tool setting device can be equipped to correct the position of the cutting tool and improve the cutting accuracy.

[0067] In some optional embodiments, a plurality of sensors can be installed on the base frame for real-time monitoring of the running state data of the conveying mechanism and the cutting system, which will be fed back to the control system for comparison with the preset parameters to ensure that each part of the system is always running in the best state.

[0068] Specifically, the online plate shape detection device 1 is arranged opposite to the cutting system.

[0069] In specific applications, the online plate shape detection device 1 is arranged opposite to the cutting system, so that the flatness of the aluminum foil can be detected before it enters the cutting system, ensuring the accuracy of the slitting process and the quality of the finished product.

[0070] Through the detection equipment 3 in the online plate shape detection device 1, the image or measurement data of the aluminum foil surface can be continuously obtained during the conveying process of the aluminum foil. These data are transmitted to the control system in real time, and the control system evaluates the flatness condition of the aluminum foil according to the detection data and adjusts or takes other measures in time when an abnormality is found, such as automatically adjusting the tension control system of the slitting device, or suspending the slitting process in serious cases to prevent the generation of unqualified products.

[0071] Specifically, the battery aluminum foil flatness detection device for the slitting device further comprises a storage device.

[0072] The storage device is used to store the detection data of the online plate shape detection device 1.

[0073] In specific applications, the online plate shape detection device 1 can detect the internal stress of the battery aluminum foil in real time through the force sensor, and the flatness condition of the battery aluminum foil can be determined according to the detected internal stress. These detection data (internal stress and flatness detection results) will be transmitted to the control system in real time and stored in the storage device. The storage capacity and storage method can be flexibly set to ensure that the data can be saved for a long time and can be retrieved at any time. By setting the storage device, the battery aluminum foil flatness detection data obtained by the online plate shape detection device 1 can be stored in real time, ensuring that the battery aluminum foil after slitting meets the quality requirements. At the same time, these data can be used for subsequent quality analysis and control, thereby improving the quality monitoring capability of the entire slitting process.

[0074] Through this technical solution, by arranging the online plate shape detection device opposite to the battery aluminum foil conveyed into the battery aluminum foil slitting device, the flatness of the battery aluminum foil during the slitting process can be detected in real time, and possible flatness problems can be found and corrected in time, ensuring that the battery aluminum foil after slitting has good flatness and improving the accuracy and quality of the battery aluminum foil slitting.
