Description

Technical Field

[0001] This utility model relates to the field of electrode manufacturing, and in particular to a cutting mechanism and an online monitoring device for the resistance performance of electrode films. Background Technology

[0002] Electrode coating is a key step in battery manufacturing. It involves coating active materials onto current collectors to create electrodes, where electrochemical reactions occur to achieve energy storage and release. Electrode coating includes traditional wet processes and dry electrode technologies.

[0003] Traditional wet processing involves mixing electrode materials with liquid solvents to form a slurry, which is then coated onto metal foil. The wet electrode sheets require oven drying, and the positive electrode sheets need to be rolled up and baked for 12-24 hours. This process is energy-intensive, and the NMP organic solvent used in the preparation of the positive electrode slurry is volatile and has low toxicity, requiring recycling and re-distillation. This process has significant drawbacks and is not conducive to rapid and economical production.

[0004] Dry electrode technology involves mixing active materials with binders and then rolling them onto metal foil under temperature and pressure, eliminating the need for a drying process and reducing costs and energy consumption. Although the process is more complex, it reduces drying and solvent recovery steps, thereby lowering energy consumption and costs.

[0005] In dry electrode technology, mixing involves solid-solid contact, resulting in poor flowability and the risk of uneven mixing, which may lead to poor cell impedance consistency. Furthermore, there is currently a lack of reliable and rapid methods for detecting powder consistency. Utility Model Content

Slides are symmetrically opened on the inner walls of the opposite sides of the first groove and the second groove. Snap-fit ​​blocks are symmetrically fixedly connected to the side walls near both ends of the snap-fit ​​strip, and the snap-fit ​​blocks are slidably inserted into the slides. Several sets of toothed grooves are arranged on the top of the snap-fit ​​strip, and the gears mesh with the toothed grooves.

[0032] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0033] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0034] Reference Figures 1 to 7 This embodiment provides a cutting mechanism, which includes a support frame 100, which is placed horizontally in the moving direction of the electrode diaphragm A.

[0035] The support frame 100 is a rod-shaped structure and is fixed on the conveying mechanism for conveying the electrode diaphragm A. Two sets of support frames 100 can be symmetrically arranged, located on the two sides of the electrode diaphragm A respectively, or a single support frame 100 can be arranged, in which case the support frame 100 spans the electrode diaphragm A and extends from both sides.

[0036] The tool holder 200 is installed at both ends of the support frame 100, and the cutting blade 201 is fixed on the tool holder 200.

[0037] The distance between the two cutters 201 is less than the width of the electrode film A.

[0038] Furthermore, during use, the electrode diaphragm A moves toward the blade holder 200 along with the conveying mechanism. At this time, the originally uneven edges of the electrode diaphragm A become neater after being cut by the cutter 201.

[0039] The inner walls of the adjacent two sides of the support frame 100 are respectively provided with mounting holes 101 and movable holes 102, which intersect each other.

[0040] The support frame 100 is also centrally symmetrically provided with adjustment frames 300, and the two adjustment frames 300 can slide within the mounting hole 101 and the movable hole 102.

[0041] A clamping plate 103 is fixedly connected to the side wall of the two side support frames 100 with movable through holes 102. A motor 103a is fixedly connected to the middle of one side clamping plate 103. The output shaft of the motor 103a is rotatably inserted into the other side clamping plate 103. The two side clamping plates 103 are detachably fixed to the support frame 100 by bolts. The output shaft of the motor 103a passes through the middle of the movable through hole 102 and is inserted into the other side clamping plate 103.

[0042] Furthermore, a gear 103b is fixedly sleeved on the output shaft of the motor 103a. After the motor 103a starts, the gear 103b rotates accordingly.

[0043] The adjustment frame 300 includes a frame housing 301 and a snap-fit ​​strip 302 movably connected inside it. The frame housing 301 includes a connecting plate 301a and connecting platforms 301b and auxiliary platforms 301c fixed at both ends thereon.

[0044] An embedded through hole 301a-1 is provided in the middle of the connecting plate 301a along its length direction. The embedded through hole 301a-1 divides the connecting plate 301a into two connecting rods. The embedded through hole 301a-1 extends into the connecting platform 301b and the auxiliary platform 301c, forming the first groove 301b-1 and the second groove 301b-2 respectively.

[0045] Among them, the cross-sectional structure of the connecting platform 301b and the auxiliary platform 301c is a "U" structure, and the snap-fit ​​strip 302 is slidably inserted into the groove in the middle of the "U" structure.

[0046] The snap-fit ​​strip 302 can slide within the embedded through hole 301a-1, the first groove 301b-1, and the second groove 301b-2.

[0047] Several sets of springs T are fixedly connected to the bottom of the first groove 301b-1 and the second groove 301b-2. The other end of the spring T is fixedly connected to the top of the snap-fit ​​strip 302. Slides D are also symmetrically opened on the inner walls of the opposite sides of the first groove 301b-1 and the second groove 301b-2.

[0048] The snap-fit ​​strip 302 has snap-fit ​​blocks 302a symmetrically fixedly connected to the side walls near both ends of it, and the snap-fit ​​blocks 302a are slidably inserted into the slide rail D.

[0049] The top of the snap-fit ​​strip 302 is also provided with several sets of toothed grooves 302b, and the gear 103b meshes with the toothed grooves 302b. The toothed grooves 302b are exposed within the range of the embedded perforation 301a-1.

[0050] During use, in the initial state, the springs T located in the first groove 301b-1 and the second groove 301b-2 are both in a naturally straight state. At this time, the snap-fit ​​strip 302 is stored in the embedded through hole 301a-1. The lower end face of the snap-fit ​​strip 302 is lower than the lower end face of the connecting plate 301a, while the upper end face with the toothed groove 302b is flush with the upper end face of the connecting plate 301a.

[0051] Furthermore, the height of the connecting platform 301b is the same as the width of the movable through hole 102. If it is necessary to install the two side adjustment brackets 300, the clamping plate 103 and the motor 103a cannot be installed before the adjustment brackets 300 are installed.

[0052] Furthermore, to install the adjustment bracket 300 on one side, the snap-fit ​​strip 302 must first be inserted into the embedded through hole 301a-1. At this time, the snap-fit ​​strip 302 moves slightly upward, the spring T is compressed, and the lower end surface of the snap-fit ​​strip 302 moves upward and is flush with the lower end surface of the connecting plate 301a. At this time, the entire adjustment bracket 300 can be inserted into the movable through hole 102.

[0053] Furthermore, once the snap-fit ​​strip 302 is aligned with the mounting hole 101, the spring T is no longer restricted and pops out from the embedded hole 301a-1, inserting into the mounting hole 101. At this point, the adjustment bracket 300 will not fall out of the support bracket 100.

[0054] Similarly, the other side adjustment frame 300 is installed into the support frame 100 using the above method. At this time, the clamping plate 103 and the motor 103a are installed on the side wall of the support frame 100. The output shaft of the motor 103a, which is fitted with gear 103b, passes through the upper and lower sets of snap-fit ​​strips 302 and meshes with the tooth groove 302b.

[0055] Furthermore, the gears 103b interlaced between the locking bars 302 can also limit the rebound of the locking bars 302, preventing the two sets of adjustment brackets 300 from falling off the support bracket 100.

[0056] Furthermore, when motor 103a starts, gear 103b drives the connecting platforms 301b on both sides to move. By changing the direction of motor 103a, the movement direction of the two sets of adjustment frames 300 can be controlled.

[0057] The tool holder 200 includes a fixing plate 202 and a docking plate 203 fixed to its bottom. The fixing plate 202 is fixedly connected to the side wall of the connecting platform 301b.

[0058] A mounting plate 201a is fixedly connected to one side of the cutter 201, and the mounting plate 201a is fixedly connected to the docking plate 203.

[0059] In this case, the cutter 201 cannot be angled, which is a lower-cost setting.

[0060] The tool holder 200 includes a fixing plate 202 and a plug rod 204 fixed to its bottom. The fixing plate 202 is fixedly connected to the side wall of the connecting platform 301b.

[0061] A sleeve 201b is fixedly connected to one side of the cutter 201, and the sleeve 201b is rotatably sleeved on the outside of the insert rod 204.

[0062] At this time, the cutting direction of the cutter 201 can be changed by rotating the cutter 201. Once the direction is fixed, tightening the retaining ring attached to the sleeve 201b will fix the angle. This setting can retain the electrode diaphragm A while cutting it, preventing the electrode diaphragm A from deviating during movement.

[0063] Reference Figures 1-10 In order to solve the above problems, the present invention also provides the following technical solution: an online monitoring device for the resistance performance of an electrode film, which includes the above-mentioned cutting mechanism and a monitoring unit 400, including a resistor 401, the resistor 401 being electrically connected to the cutter 201.

[0064] Among them, the resistor 401 is connected to electrical components such as industrial computers and power controllers.

[0065] The support unit 500 includes a base 501 and a conveying mechanism 502 disposed on the base 501, with the electrode diaphragm A wound around the conveying mechanism 502; the support frame 100 is fixedly connected to the base 501.

[0066] The conveying mechanism 502 includes an unwinding roller 502a and a rolling roller 502b. The unwinding roller 502a is fixedly connected to the base 501 via a tripod 502c.

[0067] The rolling rollers 502b are arranged and rotatably connected to the top of the base 501, and the electrode diaphragm A is wound between the adjacent rolling rollers 502b.

[0068] A bracket 501a is symmetrically fixedly connected to one end of the base 501 away from the unwinding wheel 502a. Several sets of rollers 501b are also rotatably connected between the brackets 501a. The rollers 501b are used to transport the mixed powder.

[0069] A support plate 501c is fixedly connected to the top of the base 501 near the unwinding roller 502a, and the top of the support plate 501c is fixedly connected to the bottom of the support frame 100.

[0070] A measuring gap B is formed between the support frame 100 and the rolling roller 502b, through which the electrode diaphragm A can pass.

[0071] A scale 104 is symmetrically fixed on the support frame 100, and the two tool holders 200 on both sides can move from the starting end to the end along the scale 104.

[0072] Specifically, in the dry electrode production process, after the powder is stirred evenly, it is laid on the roller 501b, and then further injected from the feeding groove of the rolling roller 502b. Under the repeated rolling action of multiple sets of rolling rollers 502b, a film is formed.

[0073] Furthermore, as the rolling roller 502b continues to work, the diaphragm is repeatedly rolled and stretched, and its thickness gradually decreases. When the diaphragm enters the unwinding roller 502a for lamination, it reaches the critical monitoring area.

[0074] In this area, the two cutting blades 201 are connected to the positive and negative terminals of the resistor 401 via wires. The resistor 401 is fixed to the support frame 100 with a scale 104 by insulating material. The scale 104 can precisely control the width of the diaphragm after trimming.

[0075] At this time, the resistance meter 401 starts to work, applying a controllable voltage to the electrode diaphragm A. Since the electrode diaphragm A has resistance, the current will pass through the diaphragm between the two cutters 201. According to Ohm's law, the resistance meter calculates the resistance value of the diaphragm by measuring the current flowing through the diaphragm, and continuously collects resistance data according to the pre-set test time interval.

[0076] To ensure the accuracy of resistance measurements, environmental factors also need to be monitored and corrected. Temperature and humidity sensors are installed near electrode diaphragm A to collect real-time temperature and humidity data of the environment surrounding electrode diaphragm A.

[0077] Because changes in temperature and humidity affect the resistivity of electrode materials, this environmental data is transmitted to a computer along with the resistance data. The computer then uses existing data analysis software, based on a preset algorithm, to compensate and correct the resistance values ​​using the temperature and humidity data, thereby obtaining more accurate resistance data.

[0078] During data processing, the software performs in-depth analysis of continuous real-time resistance data. On one hand, it visually displays the fluctuations in the resistance of electrode diaphragm A by plotting a curve of resistance changing over time. Large fluctuations in the resistance curve indicate significant differences in resistance at different locations on electrode diaphragm A, potentially suggesting uneven material mixing. On the other hand, it performs statistical analysis on the resistance data, calculating statistical parameters such as the average resistance and standard deviation, and setting reasonable threshold ranges. When the resistance data exceeds the threshold, the software automatically issues an alarm, alerting operators that a potential anomaly has occurred in the production process.

[0079] Based on the data analysis results, the system will make corresponding feedback and adjustments. If uneven mixing or other production problems are detected, the system will send a signal to the control system of the preceding process equipment. For example, it may control the mixing equipment to increase the mixing time or adjust the mixing speed to improve the mixing effect of the powder; or adjust the pressure, temperature, and other parameters of the rolling roller 502b to optimize the forming process of electrode diaphragm A. At the same time, the system will mark electrode diaphragm A parts with abnormal resistance values ​​and judge them as defective products, so as to facilitate subsequent targeted processing, such as manual review or automatic rejection. The entire monitoring process is closely linked and interconnected, realizing online real-time monitoring of the resistance performance of dry electrodes and effectively ensuring product quality.

[0080] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
