Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to an electrode cutting system. Background Technology

[0002] Energy conservation and emission reduction are key to sustainable development, which in turn promotes the adjustment of the energy structure and drives the development and application of battery technology. The key to the development of battery technology lies in electrochemical energy storage technology. Due to its advantages such as high energy density, good cycle capability, high operating voltage, environmental friendliness, and low self-discharge, it has been widely used in portable electronics, electric vehicles, and energy storage systems.

[0003] During battery manufacturing, battery electrodes need to be cut and sampled to test their quality. However, currently, cutting and sampling are mainly done manually, which is inefficient and results in poor consistency of the cut samples, affecting the accuracy of the tests. Utility Model Content

[0004] The main objective of this application is to provide an electrode cutting system that aims to solve the technical problem of poor consistency in cutting test samples in the prior art.

[0005] To address the aforementioned problems, this application provides an electrode cutting system. The electrode cutting system includes a conveying mechanism, a laser cutting mechanism, and a temporary storage mechanism. The conveying mechanism transports the electrode to the cutting position along the conveying direction. The laser cutting mechanism cuts the electrode at the cutting position to form a test sample. The temporary storage mechanism is located downstream of the cutting position in the gravity direction and is used to receive the test sample. The conveying direction intersects with the gravity direction. Thus, by conveying the electrode to the cutting position via the conveying mechanism, the laser cutting mechanism can cut the electrode at the cutting position to form the test sample, thereby achieving automated electrode cutting and improving the consistency of the test sample. Receiving the test sample via the temporary storage mechanism facilitates subsequent operations such as testing, improving production efficiency. Furthermore, the temporary storage mechanism's location downstream of the cutting position in the gravity direction allows for full utilization of gravity to collect the test sample, simplifying the product structure and reducing manufacturing costs.

[0006] In some embodiments, the electrode cutting system includes an electrode recycling mechanism located downstream of the conveying mechanism in the conveying direction. The electrode recycling mechanism receives the cut electrodes. Thus, the cut electrodes can be continuously conveyed along the conveying direction to the electrode recycling mechanism for recycling, thereby achieving automated recycling of the cut electrodes. This improves the automation level and integration of the electrode cutting system, and increases production efficiency.

[0007] In some embodiments, the conveying mechanism includes two conveying roller groups, which are spaced apart along the conveying direction to form a cutting position between them. This spaced-apart cutting position between the two conveying roller groups facilitates the laser cutting mechanism cutting the electrode through the gap between the two conveying roller groups, providing sufficient space for the laser cutting mechanism. Simultaneously, it allows the cut sample to fall into the temporary storage mechanism along the direction of gravity through the gap between the two conveying roller groups, thereby improving space utilization.

[0008] In some embodiments, the conveying roller assembly includes two rotating rollers spaced apart in the direction of gravity. At least one of the two rotating rollers rotates to drive the electrode sheet located between them to move along the conveying direction. Thus, the electrode sheet is moved along the conveying direction by rotating the rollers, and the movement and stopping of the electrode sheet can be controlled by controlling the rotation or stopping of the rollers. The structure is simple and cost-effective.

[0009] In some embodiments, the conveying roller assembly includes at least one drive component. The drive component includes a mounting bracket and a lifting drive. The mounting bracket is connected to the lifting drive and a rotating roller. The lifting drive is used to drive the mounting bracket to move the rotating roller closer to or away from another rotating roller in the direction of gravity. Thus, the drive component can drive the rotating roller closer to or away from another rotating roller in the direction of gravity. When the two rotating rollers are close to each other, they can clamp the electrode sheet, which facilitates the two rotating rollers to better move the electrode sheet along the conveying direction, improving the stability of the electrode sheet so that the laser cutting mechanism can cut the electrode sheet. When the two rotating rollers are far apart, the electrode sheet located upstream of the conveying roller assembly in the conveying direction can accurately enter between the two rotating rollers.

[0010] In some embodiments, the conveying mechanism further includes a conveying platform located upstream of the two conveying roller groups in the conveying direction. The conveying platform is used to convey the electrode sheet to the two conveying roller groups along the conveying direction. Thus, conveying the electrode sheet to the two conveying roller groups via the conveying platform along the conveying direction helps to improve the conveying stability of the electrode sheet and enhance the automation level of the electrode sheet cutting system.

[0011] In some embodiments, the electrode cutting system includes a pneumatic mechanism, and the conveying platform is provided with an air suction port. The pneumatic mechanism is used to apply negative pressure to the electrode located on the conveying platform through the air suction port. Therefore, by applying negative pressure to the electrode on the conveying platform through the air suction port, the pneumatic mechanism can effectively improve the stability of the electrode during the conveying process along the conveying direction, reduce the risk of the electrode shifting on the conveying platform, and improve the reliability of the electrode cutting system.

[0012] In some embodiments, the conveying mechanism further includes a first sensor, which is positioned opposite and spaced apart from the side of the conveying platform used to convey the electrode sheet. This allows the first sensor to detect the electrode sheet and obtain its state information, enabling the laser cutting mechanism to plan the cutting of the electrode sheet. Furthermore, the relative spacing between the first sensor and the conveying platform reduces the risk of interference between the first sensor and the electrode sheet.

[0013] In some embodiments, the laser cutting mechanism includes a laser and a lens assembly. The laser generates laser light, and the lens assembly is located in the laser's optical path and transmits the laser light to the cutting position. Thus, the laser and lens assembly work together to ensure precise and stable transmission of the laser light onto the electrode at the cutting position, thereby improving the accuracy and stability of the laser cutting mechanism in cutting the electrode and enhancing the consistency of the sample under test.

[0014] In some embodiments, the lens assembly and the temporary storage mechanism are located on either side of the cutting position in the direction of gravity. Thus, by arranging the lens assembly and the temporary storage mechanism on either side of the cutting position in the direction of gravity, the lens assembly can transmit laser light to the cutting position along the direction of gravity, allowing the cut sample to fall into the temporary storage mechanism under gravity. This reduces the difficulty of cutting the sample by the laser cutting mechanism and improves space utilization.

[0015] In some embodiments, the electrode cutting system further includes a transfer mechanism and a detection mechanism. The transfer mechanism is used to transfer the sample to be tested from the temporary storage mechanism to the detection mechanism. Thus, by transferring the sample to be tested from the temporary storage mechanism to the detection mechanism, the automation level of the electrode cutting system is improved. Furthermore, by integrating the transfer mechanism and the detection mechanism into the electrode cutting system, the integration level of the electrode cutting system is improved, thereby increasing production efficiency.

[0016] In some embodiments, the detection mechanism includes a weight detector and a moisture detector. Thus, the weight of the sample can be measured using the weight detector, and the moisture content of the sample can be measured using the moisture detector, allowing for multi-faceted detection of the sample. This improves the accuracy of sample detection, enhances the integration of the electrode cutting system, and increases detection efficiency.

[0017] In some embodiments, the temporary storage mechanism includes a movable temporary storage box that moves between a first position and a second position different from the first position. The movable temporary storage box is used to receive the sample to be tested at the first position, and the transfer mechanism is used to receive the sample to be tested at the second position. Thus, the sample to be tested can be transferred between the first and second positions via the movable temporary storage box, improving the automation level of the temporary storage mechanism while reducing the difficulty for the transfer mechanism to acquire the sample to be tested, thereby increasing production efficiency.

[0018] In some embodiments, the transfer mechanism includes a transfer support and a transfer body. The transfer support extends along the transfer direction, and the transfer body and the transfer support are slidably connected. The transfer body moves relative to the transfer support along the transfer direction, with a second position located in the transfer direction. The transfer body is used to transfer the sample to be tested. Thus, the sample to be tested can be transferred along the transfer direction by sliding the transfer body on the transfer support, improving the automation level of the transfer mechanism while maintaining a simple structure and saving costs.

[0019] In some embodiments, the detection mechanism includes a weight detector and a moisture detector, which are arranged sequentially in the transfer direction, with the weight detector positioned closer to the moisture detector at a second position. This arrangement allows the transfer body to prioritize weight detection of the sample via the weight detector during the transfer of the sample along the transfer direction, saving transfer distance and reducing the risk of interference with weight detection results due to prioritizing moisture detection, thus improving the reliability of the laser cutting mechanism.

[0020] In some embodiments, the electrode cutting system further includes a sample recovery mechanism. In the transfer direction, the moisture detector is positioned closer to the sample recovery mechanism than the weight detector, and the transfer body is used to transfer the sample to be tested to the sample recovery mechanism. Therefore, by positioning the moisture detector closer to the sample recovery mechanism than the weight detector in the transfer direction, the transfer body can continue transferring the sample to the sample recovery mechanism along the transfer direction after moisture detection, saving transfer distance, improving the integration of the electrode cutting system, and increasing transfer efficiency.

[0021] In some embodiments, the electrode cutting system includes an operating table and a controller, with the conveying mechanism, laser cutting mechanism, temporary storage mechanism, and controller mounted on the operating table. Thus, the operating table provides fixation and support for the conveying mechanism, laser cutting mechanism, temporary storage mechanism, and controller, improving cutting stability. Furthermore, integrating the conveying mechanism, laser cutting mechanism, temporary storage mechanism, and controller onto the operating table significantly improves the integration of the electrode cutting system. Simultaneously, the controller can control the actions of the conveying mechanism, laser cutting mechanism, and temporary storage mechanism, enhancing the flexibility of the electrode cutting system.

[0022] In some embodiments, the electrode cutting system further includes a detection mechanism. The operating table includes a first platform and a second platform spaced apart. The conveying mechanism, laser cutting mechanism, temporary storage mechanism, and controller are mounted on the first platform, while the detection mechanism is mounted on the second platform. Thus, the first and second platforms separate the detection mechanism from the conveying mechanism, laser cutting mechanism, temporary storage mechanism, and controller, reducing the risk of vibrations from these components interfering with the detection results of the detection mechanism, and improving the stability and reliability of the detection mechanism.

[0023] In some embodiments, the electrode cutting system further includes a second sensor for acquiring images of the sample under test. Thus, image information of the sample under test can be acquired via the second sensor, allowing for processing planning based on the image information.

[0024] In some embodiments, the electrode cutting system further includes a pneumatic mechanism for applying negative pressure to the cutting position. This allows the pneumatic mechanism to apply negative pressure to the cutting position, thereby removing dust, debris, and other impurities near the cutting position and reducing the impact of impurities on electrode cutting and sample testing.

[0040] Currently, judging from market trends, battery applications are becoming increasingly widespread. Batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also extensively in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. With the continuous expansion of battery applications, market demand is also constantly increasing.

[0041] During battery manufacturing, battery electrodes need to be cut and sampled to test their quality. However, currently, cutting and sampling are mainly done manually, which is inefficient and results in poor consistency of the cut samples, affecting the accuracy of the tests.

[0042] To address the technical problems existing in related technologies, an electrode cutting system is provided. The system includes a conveying mechanism that transports electrode sheets to a cutting position along a conveying direction, allowing a laser cutting mechanism to cut the electrode sheets at the cutting position to form a test sample. This achieves automated electrode cutting, improves the consistency of the test sample, and simultaneously receives the test sample through a temporary storage mechanism, facilitating subsequent operations such as sample testing.

[0043] A battery typically includes a casing and individual battery cells, with the individual cells housed within the casing. A battery may contain multiple individual cells, which can be connected in series, parallel, or a combination thereof. A combination of series and parallel connections refers to multiple individual cells being connected in both series and parallel configurations. Multiple individual cells can be directly connected in series, parallel, or a combination thereof, and then the entire assembly is housed within the casing. Alternatively, a battery can consist of multiple individual cells first connected in series, parallel, or a combination thereof to form a battery module, and then these modules are connected in series, parallel, or a combination thereof to form a single unit housed within the casing. The battery may also include other structures; for example, it may include a busbar for electrical connection between the multiple individual battery cells.

[0044] Battery cells are manufactured using two methods: stacking and winding. Stacked cells offer uniform current collection, lower internal resistance, and higher specific power. However, to achieve this, extremely high precision is required for the molds, resulting in high equipment investment, complex processes, and low production efficiency. Winded cells, on the other hand, are simpler to manufacture, with less stringent precision requirements for equipment during the cell fabrication and assembly processes. They offer high production efficiency and lower costs. In terms of performance, wound cells boast excellent high and low temperature performance, very rapid charging, ultra-long lifespan, stable high output voltage, robust structure, and strong shock resistance.

[0045] A battery cell is the smallest unit that makes up a battery. A battery cell may include a casing, electrode assemblies, and other functional components. The electrode assembly is the component in the battery cell where electrochemical reactions occur. The casing may contain one or more electrode assemblies. Electrode assemblies are mainly formed by winding or stacking positive and negative electrode plates, and usually a separator is provided between the positive and negative electrode plates.

[0046] The electrode can be either a positive or negative electrode. The portion of the electrode containing active material constitutes the main body of the electrode assembly, while the portion without active material forms individual tabs. During the charging and discharging process of the battery, the active material reacts with the electrolyte, and the tabs connect to the electrode terminals to form a current loop. The active material can be coated onto the electrode in the form of a slurry to form a film layer, which can then be fixed onto the electrode by baking and rolling. The slurry material can include, but is not limited to, lithium phosphates, lithium transition metal oxides and their respective modified compounds, artificial graphite, natural graphite, soft carbon, hard carbon, silicon-based materials, tin-based materials, and lithium titanate.

[0047] Combination Figure 1 , Figure 1 This is a first structural schematic diagram of an electrode cutting system according to one or more embodiments of this application.

[0048] The electrode cutting system 1 includes a conveying mechanism 10, a laser cutting mechanism 20, and a temporary storage mechanism 30. The conveying mechanism 10 conveys the electrode 2 to the cutting position 11 along the conveying direction x1. The laser cutting mechanism 20 is used to cut the electrode 2 at the cutting position 11 to form the sample to be tested 3. The temporary storage mechanism 30 is located downstream of the cutting position 11 in the gravity direction x2. The temporary storage mechanism 30 is used to receive the sample to be tested 3. The conveying direction x1 and the gravity direction x2 intersect.

[0049] The conveying mechanism 10 can convey the electrode 2 to the cutting position 11 along the conveying direction x1. The conveying mechanism 10 can be, but is not limited to, a conveyor belt, conveyor chain, conveyor roller, etc. The conveying mechanism 10 can convey the electrode 2 along the conveying direction x1 at a preset speed. The preset speed can be set according to actual needs. For example, the preset speed can be set to, but is not limited to, greater than or equal to 0.1 m / s and less than or equal to 1 m / s. Optionally, the preset speed can be set to, but is not limited to, 0.1 m / s, 0.3 m / s, 0.5 m / s, 0.8 m / s, 1 m / s, etc. The laser cutting mechanism 20 can generate a laser and cut the electrode 2 at the cutting position 11 using the laser. For example, the laser cutting mechanism 20 can generate a laser and transmit the laser to the electrode 2 at the cutting position 11, thereby cutting out the corresponding test sample 3 according to the preset pattern. Here, the preset pattern refers to the specific shape corresponding to the test sample 3. The preset pattern can be any shape, including but not limited to, a circle, a square, a triangle, etc. Optionally, the preset pattern can be a circle. As an example, when the preset shape is circular, the test sample 3 cut from the electrode 2 by laser cutting is circular. Furthermore, the laser cutting mechanism 20 can also cut test samples 3 of corresponding sizes according to preset dimensions. Taking a circular preset shape as an example, the size of the test sample 3 cut by the laser cutting mechanism 20 can also be different depending on the preset radius of the circle. The specific preset shape and preset size can be set according to actual needs. For example, taking a circular preset image as an example, the preset radius can be set to greater than or equal to 20mm and less than or equal to 25mm. Specifically, the preset radius can be set to, but is not limited to, 20mm, 21mm, 22mm, 23mm, 24mm, or 25mm, etc. Optionally, the preset radius can be set to 22mm. It should be noted that the conveying mechanism 10 can keep the electrode 2 in a moving or stopped state in the conveying direction x1. For example, during the process of the laser cutting mechanism 20 cutting the electrode 2, the conveying mechanism 10 can stop conveying the electrode 2 to keep the electrode 2 relatively stationary with the laser cutting mechanism 20, thereby improving the stability of the cutting.

[0050] The laser cutting mechanism 20 can transmit laser light to different positions on the same electrode 2. For example, a film-coated region and a non-film-coated region can be formed on the electrode 2. The film-coated region refers to the area with a film layer, and the non-film-coated region refers to the area without a film layer. The laser cutting mechanism 20 can perform corresponding cutting based on the actual distribution of the film-coated and non-film-coated regions on each electrode 2. The laser generated by the laser cutting mechanism 20 can contact the electrode 2 in any direction intersecting the extension direction of the electrode 2 to cut it. For example, the laser generated by the laser cutting mechanism 20 can contact the electrode 2 in a direction perpendicular to the main surface of the electrode 2, or it can contact the electrode 2 in a direction oblique to the main surface of the electrode 2. The laser cutting mechanism 20 can cut one, two, or more test samples 3 from the same electrode 2. The specific number of test samples 3 can be set according to actual needs. Understandably, compared to manually cutting the sample 3 with a tool, laser-cut sample 3 has smoother and flatter boundaries, and produces fewer burrs and debris during the cutting process, effectively improving the consistency of sample 3. It should be noted that the cutting speed of the laser cutting mechanism 20 can be set according to actual needs. For example, the cutting speed of the laser cutting mechanism 20 can be greater than or equal to 0.1 s / PCS and less than or equal to 0.5 s / PCS. Specifically, the speed can be, but is not limited to, 0.1 / PCS, 0.2 / PCS, 0.3 / PCS, 0.4 / PCS, or 0.5 / PCS, etc.

[0051] The temporary storage mechanism 30 is located downstream of the cutting position 11 in the gravity direction x2. The temporary storage mechanism 30 is used to receive the sample 3 to be tested. The transport direction x1 intersects with the gravity direction x2. The temporary storage mechanism 30 may have a temporary storage space for temporarily holding and accommodating the sample 3 to be tested. For example, the temporary storage mechanism 30 may include, but is not limited to, a temporary storage platform, a temporary storage container, etc., wherein the temporary storage container may include, but is not limited to, a temporary storage basin, a temporary storage box, a temporary storage cage, a temporary storage basket, etc. The intersection of the transport direction x1 and the gravity direction x2 means that the transport direction x1 can be any direction forming an angle with the gravity direction x2. Optionally, the transport direction x1 can be perpendicular to the gravity direction x2. In some application scenarios, after the laser cutting mechanism 20 completely cuts the sample 3 to be tested from the electrode 2, causing the sample 3 to be completely separated from the electrode 2, the sample 3 can naturally fall into the temporary storage mechanism 30 under the action of gravity.

[0052] Through the above implementation method, the electrode 2 is conveyed to the cutting position 11 by the conveying mechanism 10 so that the laser cutting mechanism 20 can cut the electrode 2 at the cutting position 11 to form the test sample 3, thereby realizing automated cutting of the electrode 2 and improving the consistency of the test sample 3. The test sample 3 is received by the temporary storage mechanism 30, which facilitates subsequent operations such as testing of the test sample 3 and improves production efficiency. At the same time, the temporary storage mechanism 30 is located downstream of the cutting position 11 in the gravity direction x2, which is conducive to making full use of gravity to collect the test sample 3, simplifying the product structure and reducing the product manufacturing cost.

[0053] In some application scenarios, the width of electrode 2 can be greater than or equal to 150mm and less than or equal to 180mm. For example, the width of electrode 2 can be greater than or equal to 150mm and less than or equal to 160mm, or greater than or equal to 160mm and less than or equal to 180mm. Specifically, the width of electrode 2 can be, but is not limited to, 150mm, 160mm, 170mm, 175mm, or 180mm, etc. The length of electrode 2 can be greater than or equal to 1200mm and less than or equal to 1600mm. For example, the length of electrode 2 can be greater than or equal to 1200mm and less than or equal to 1500mm, or greater than or equal to 1300mm and less than or equal to 1600mm. Specifically, the length of electrode 2 can be, but is not limited to, 1300mm, 1350mm, 1400mm, 1450mm, 1500mm, or 1600mm, etc. Optionally, the length of electrode 2 is 1400mm.

[0054] Combination Figures 2-3 , Figure 2 This is a second structural schematic diagram of an electrode cutting system according to one or more embodiments of this application; Figure 3 This is a third structural schematic diagram of an electrode cutting system according to one or more embodiments of this application.

[0055] In some embodiments, the electrode cutting system 1 includes an electrode recycling mechanism 40, which is located downstream of the conveying mechanism 10 in the conveying direction x1. The electrode recycling mechanism 40 is used to receive the cut electrode 2. The recycling mechanism can be, but is not limited to, a recycling bin, a recycling box, and a recycling line, etc., wherein the recycling bin and recycling box can be used to contain and store the cut electrode 2, and the recycling line can receive the cut electrode 2 and convey the electrode 2 to the recycling area for recycling processing. The electrode recycling mechanism 40 is located downstream of the conveying mechanism 10 in the conveying direction x1. It is understood that after the electrode 2 is cut, the conveying mechanism 10 can continue to convey the electrode 2 along the conveying direction x1 so as to convey the electrode 2 to the electrode recycling mechanism 40. It is understood that by integrating the electrode recycling mechanism 40 into the electrode cutting system 1, there is no need to set up an additional independent electrode recycling station. For example, the operator can realize multi-step processing such as electrode cutting and electrode recycling through a single station corresponding to the electrode cutting system 1, thereby improving the integration of the electrode cutting system 1. Therefore, the cut electrode 2 can be conveyed along the conveying direction x1 to the electrode recycling mechanism 40 through the conveying mechanism 10, so that the electrode recycling mechanism 40 can recycle the cut electrode 2, thereby realizing the automated recycling of the cut electrode 2, improving the automation level of the electrode cutting system 1, and also improving the integration level of the electrode cutting system 1, and improving production efficiency.

[0056] In some embodiments, the conveying mechanism 10 includes two conveying roller groups 12, which are spaced apart along the conveying direction x1 to form a cutting position 11 between the two conveying roller groups 12. Each conveying roller group 12 may include one, two or more conveying rollers, which can rotate the conveying electrode 2. Two conveyor roller groups 12 can be spaced apart along the conveying direction x1 to form a cutting position 11 between the two conveyor roller groups 12. For example, the two conveyor roller groups 12 are spaced apart along the conveying direction x1, and the electrode 2 can be at least partially suspended at the interval between the two conveyor roller groups 12, that is, the electrode 2 can be at least partially suspended at the cutting position 11. The laser cutting mechanism 20 can generate laser and transmit it to the electrode 2 located at the cutting position 11. Specifically, during the process of the electrode 2 being conveyed to the cutting position 11 along the conveying direction x1, one end of the electrode 2 in the conveying direction x1 can first pass over the conveyor roller group 12 located upstream of the conveying direction x1 and continue to move along the conveying direction x1, and then reach the conveyor roller group 12 located downstream of the conveying direction x1. After the laser cutting mechanism 20 completes the cutting, the other end of the electrode 2 in the conveying direction x1 can also pass over the conveyor roller group 12 located upstream of the conveying direction x1 and continue to move along the conveying direction x1, and then reach the conveyor roller group 12 located downstream of the conveying direction x1. Understandably, during the process of the laser cutting mechanism 20 cutting the electrode 2 located at the cutting position 11, when the sample to be tested 3 is completely separated from the original electrode 2, the sample to be tested 3 can fall into the temporary storage mechanism 30 from the gap between the two conveying roller groups 12 under the action of gravity. Thus, by setting the cutting position 11 at intervals along the conveying direction x1 between the two conveying roller groups 12, the laser cutting mechanism 20 can cut the electrode 2 through the gap between the two conveying roller groups 12, thereby providing sufficient space for the laser cutting mechanism 20. Simultaneously, it facilitates the falling of the cut sample to be tested 3 into the temporary storage mechanism 30 through the gap between the two conveying roller groups 12 along the gravity direction x2, thereby improving space utilization.

[0057] In some embodiments, the conveying roller assembly 12 includes two rotating rollers 121, which are spaced apart in the gravity direction x2. At least one of the two rotating rollers 121 rotates to move the electrode 2 located between them along the conveying direction x1. The electrode 2 can move along the conveying direction x1 through the gap between the two rotating rollers 121. One of the two rotating rollers 121 may rotate while the other remains stationary, or both rotating rollers 121 may rotate. The rotation of the two rotating rollers 121 can be active or passive. For example, one of the two rotating rollers 121 may rotate while the other remains stationary. The rotating roller 121 may actively rotate to move the electrode 2 between them along the conveying direction x1. Alternatively, both rotating rollers 121 may rotate, with one rotating roller 121 actively rotating and the other passively rotating, or both rotating rollers 121 may actively rotate. It should be noted that the rotating roller 121 can be actively rotated by means of, but not limited to, a drive motor, a pneumatic motor, and a hydraulic motor. It should be noted that the rotation state of the rotating roller 121 is controllable. For example, when conveying the electrode 2, the rotating roller 121 can be in a rotating state, and when the laser cutting mechanism 20 is cutting the electrode 2, the rotating roller 121 can be in a stationary state. It can be understood that the electrode 2 is located between the two rotating rollers 121 in the gravity direction x2, and the two rotating rollers 121 can also provide support for the electrode 2, improving the stability of the electrode 2 conveying. Therefore, the rotating roller 121 drives the electrode 2 to move along the conveying direction x1, and the movement and stopping of the electrode 2 can be controlled by controlling the rotation or stopping of the rotating roller 121. The structure is simple and cost-effective.

[0058] In some embodiments, the conveying roller group 12 includes at least one drive assembly 122. The drive assembly 122 includes a mounting bracket 1221 and a lifting drive 1222. The mounting bracket 1221 is connected to the lifting drive 1222 and a rotating roller 121. The lifting drive 1222 drives the mounting bracket 1221 to move the rotating roller 121 closer to or away from another rotating roller 121 in the gravity direction x2. The mounting bracket 1221 can provide fixation and support for the rotating roller 121. The lifting drive 1222 can be, but is not limited to, a drive motor, a drive cylinder, etc. The lifting drive 1222 can drive the mounting bracket 1221 to move the rotating roller 121 closer to or further away from the other rotating roller 121 in the gravity direction x2. It can be understood that when one rotating roller 121 is close to the other rotating roller 121, the two rotating rollers 121 can clamp the electrode 2 between the two rotating rollers 121. When one rotating roller 121 is away from the other rotating roller 121, it is convenient for the electrode 2 located upstream of the conveying roller group 12 in the conveying direction x1 to accurately enter between the two rotating rollers 121. For example, when the electrode 2 is conveyed to the cutting position 11, the lifting drive 1222 can drive the mounting bracket 1221 to move the rotating roller 121 closer to another rotating roller 121 in the gravity direction x2, thereby clamping the electrode 2 with the two rotating rollers 121. With the electrode 2 clamped by the two rotating rollers 121, both rotating rollers 121 can be stationary, thus pressing and fixing the electrode 2, improving the stability of the electrode 2, and facilitating the laser cutting mechanism 20 to cut the electrode 2. With the electrode 2 clamped by the two rotating rollers 121, at least one of the two rotating rollers 121 can be rotating, thereby moving the electrode 2 along the conveying direction x1, further improving the stability of the electrode 2. It is understandable that when the drive assembly 122 drives the mounting bracket 1221 to move the rotating roller 121 away from the other rotating roller 121, the gap between the two rotating rollers 121 increases, and the electrode 2 upstream of the conveying roller group 12 can accurately enter between the two rotating rollers 121. After the electrode 2 enters between the two rotating rollers 121, the drive assembly 122 can also drive the mounting bracket 1221 to move the rotating roller 121 closer to the other rotating roller 121, thereby clamping the electrode 2. Therefore, the drive assembly 122 can drive the rotating roller 121 to move closer to or further away from the other rotating roller 121 in the gravity direction x2. When the two rotating rollers 121 are close to each other, they can clamp the electrode 2, which makes it easier for the two rotating rollers 121 to better drive the electrode 2 to move along the conveying direction x1, improving the stability of the electrode 2 so that the laser cutting mechanism 20 can cut the electrode 2. When the two rotating rollers 121 are far apart, the electrode 2 located upstream of the conveying roller group 12 in the conveying direction x1 can accurately enter between the two rotating rollers 121.

[0059] In some embodiments, the conveying mechanism 10 further includes a conveying platform 13, which is located upstream of the two conveying roller groups 12 in the conveying direction x1. The conveying platform 13 is used to convey the electrode sheet 2 to the two conveying roller groups 12 along the conveying direction x1. The conveying platform 13 can carry and convey the electrode sheet 2. The conveying platform 13 may include, but is not limited to, a conveyor belt, etc. The conveying platform 13 may have a support surface extending in the conveying direction x1, thereby carrying the electrode sheet 2 through the support surface and driving the electrode sheet 2 to move along the conveying direction x1. The area of ​​the support surface may be larger than the area of ​​the electrode sheet 2, thereby stably providing support for the electrode sheet 2. Therefore, conveying the electrode sheet 2 to the two conveying roller groups 12 along the conveying direction x1 by the conveying platform 13 is beneficial to improving the conveying stability of the electrode sheet 2 and improving the automation level of the electrode cutting system 1.

[0060] In some embodiments, the electrode cutting system 1 includes a pneumatic mechanism 50, and the conveying platform 13 is provided with a suction port 131. The pneumatic mechanism 50 is used to apply negative pressure to the electrode 2 located on the conveying platform 13 through the suction port 131. The pneumatic mechanism 50 may include, but is not limited to, a vacuum generator, a vacuum pump, etc. It is understood that by applying negative pressure to the electrode 2 located on the conveying platform 13 through the suction port 131, the pneumatic mechanism 50 can stably adsorb the electrode 2 onto the conveying platform 13 through the negative pressure, thereby improving the stability of the electrode 2 during the conveying process. Exemplarily, the conveying platform 13 may have a supporting surface for supporting the electrode 2, and the suction port 131 may be formed on the supporting surface and communicate with the pneumatic mechanism 50. In some application scenarios, the conveying platform 13 includes a conveyor belt, and the suction port 131 may penetrate through the opposite two surfaces of the conveyor belt. Therefore, the pneumatic mechanism 50 applies negative pressure to the electrode 2 on the conveying platform 13 through the suction hole 131, which can effectively improve the stability of the electrode 2 during the conveying process along the conveying direction x1 on the conveying platform 13, reduce the risk of the electrode 2 shifting on the conveying platform 13, and improve the reliability of the electrode cutting system 1.

[0061] In some embodiments, the electrode cutting system 1 further includes a pneumatic mechanism 50, which applies negative pressure to the cutting position 11. It is understood that in the working environment, dust and other impurities may fall into the cutting position 11. Simultaneously, during the laser cutting mechanism 20's cutting of the electrode 2, some debris and other impurities from the electrode 2 may remain. These dust and debris may adversely affect the electrode 2 cutting process. The pneumatic mechanism 50 applies negative pressure to the cutting position 11, which can absorb and collect dust and debris, thereby effectively improving the cleanliness of the cutting position 11 and mitigating the risk of dust and debris remaining in the cutting position 11 for a long time and adversely affecting the cutting of the electrode 2. Therefore, by applying negative pressure to the cutting position 11 through the pneumatic mechanism 50, dust and debris near the cutting position 11 can be absorbed, reducing the impact of impurities on the cutting of the electrode 2 and the detection of the sample to be tested.

[0062] In some embodiments, the conveying mechanism 10 further includes a first sensor 14, which is opposite to and spaced from the side of the conveying platform 13 used to convey the electrode 2. The first sensor 14 can be used to acquire state information of the electrode 2, wherein the state information refers to information used to characterize one or more attributes of the electrode 2. For example, the state information may include, but is not limited to, the size, shape, film size, and number of film regions of the electrode 2, etc., wherein the size may include, but is not limited to, the length and width of the electrode 2, etc., the film size may include, but is not limited to, the width of the film layer coated on the electrode 2, etc., and the number of film regions refers to the number of areas on the electrode 2 coated with the film layer. Exemplarily, the first sensor 14 may include, but is not limited to, a color mark sensor, an image sensor, etc., wherein, taking a color mark sensor as an example, the color mark sensor can be used to detect the film size and the number of film regions of the electrode 2. It is understood that the laser cutting mechanism 20 can perform cutting planning based on the state information of the electrode 2 acquired by the first sensor 14, wherein the cutting planning may include the specific position of the sample 3 to be cut on the electrode 2, the shape and size of the sample 3 to be cut, etc. The first sensor 14 and the conveying platform 13 are positioned opposite each other and spaced apart on the side used to convey the electrode 2. This allows the first sensor 14 to accurately and efficiently detect the electrode 2, thereby obtaining its status information, while minimizing interference from the first sensor 14 during the electrode 2 conveying process. Thus, the first sensor 14 can detect the electrode 2 and obtain its status information, enabling the laser cutting mechanism 20 to plan the cutting of the electrode 2. Furthermore, the relative spacing between the first sensor 14 and the conveying platform 13 reduces the risk of interference between the first sensor 14 and the electrode 2.

[0063] In some embodiments, the laser cutting mechanism 20 includes a laser 21 and a lens assembly 22. The laser 21 generates laser light, and the lens assembly 22 is located in the optical path of the laser and transmits the laser light to the cutting position 11. The laser 21 is a device capable of emitting laser light, and the lens assembly 22 is capable of receiving the laser light generated by the laser 21 and adjusting the laser light so that it is transmitted to the cutting position 11 to cut the electrode 2. The lens assembly 22 may include, but is not limited to, a galvanometer and a field lens. The galvanometer can be used to adjust the deflection angle of the laser light, thereby controlling the specific position of the laser transmission at the cutting position 11. The field lens can be used to adjust the focusing area of ​​the laser light, thereby facilitating effective cutting of the electrode 2. Thus, the laser 21 and the lens assembly 22 work together to ensure that the laser light is accurately and stably transmitted to the electrode 2 at the cutting position 11, thereby improving the accuracy and stability of the laser cutting mechanism 20 in cutting the electrode 2, and contributing to improved consistency of the sample 3 under test.

[0064] In some embodiments, the lens assembly 22 and the temporary storage mechanism 30 are located on opposite sides of the cutting position 11 in the gravity direction x2. The temporary storage mechanism 30 is located downstream of the cutting position 11 in the gravity direction x2, and the lens assembly 22 is located upstream of the cutting position 11 in the gravity direction x2. This reduces the difficulty for the lens assembly 22 to transmit laser light to the cutting position 11 and facilitates the sample 3 to fall into the temporary storage mechanism 30 under gravity. Optionally, the lens assembly 22 and the temporary storage mechanism 30 can be respectively arranged corresponding to the cutting position 11 in the gravity direction x2. Specifically, the orthographic projection of the lens assembly 22 in the gravity direction x2 and the orthographic projection of the temporary storage mechanism 30 in the gravity direction x2 can at least partially overlap. Therefore, by setting the lens assembly 22 and the temporary storage mechanism 30 on both sides of the cutting position 11 in the gravity direction x2, the lens assembly 22 can transmit the laser along the gravity direction x2 to the cutting position 11, so that the cut sample 3 falls into the temporary storage mechanism 30 under the action of gravity, which reduces the difficulty of the laser cutting mechanism 20 cutting the sample 3 and improves the space utilization.

[0065] In some embodiments, the electrode cutting system 1 further includes a second sensor 100, which is used to acquire images of the sample 3 under test. The second sensor 100 can acquire images of the sample 3 under test, and the second sensor 100 can be, but is not limited to, an image sensor, such as a charge-coupled device (CCD). It is understood that the subsequent processing of the sample 3 under test can be planned based on the image information of the sample 3 under test acquired by the second sensor 100. For example, when the image information of the sample 3 under test indicates that the sample 3 under test meets the sampling criteria, the sample 3 under test can be planned for detection; when the image information of the sample 3 under test indicates that the sample 3 under test does not meet the sampling criteria, the sample 3 under test can be planned for recycling. The sampling criteria refer to preset standards for the shape, size, edge smoothness, etc. of the sample 3 under test. For example, the sampling criteria can be set to the size of the sample 3 under test being within a preset range. When the size of the sample 3 under test is within the preset range, it is considered that the sample 3 under test meets the sampling criteria; when the size of the sample 3 is outside the preset range, it is considered that the sample 3 under test does not meet the sampling criteria. Specifically, the detection plan may include, but is not limited to, weight and moisture detection of the sample 3 to be tested that meets the sampling standards, while the recovery plan may involve directly recovering the sample 3 to be tested that does not meet the sampling standards. Thus, image information of the sample 3 to be tested can be acquired by the second sensor 100, so that the processing plan for the sample 3 to be tested can be planned based on the image information.

[0067] In some embodiments, the electrode cutting system 1 further includes a transfer mechanism 60 and a detection mechanism 70. The transfer mechanism 60 is used to transfer the sample 3 to be tested from the temporary storage mechanism 30 to the detection mechanism 70. The detection mechanism 70 can be used to detect the sample 3 to be tested. Exemplarily, the detection mechanism 70 can be used to detect, but is not limited to, the weight, water content, film thickness, etc., of the sample 3 to be tested. The transfer mechanism 60 is used to transfer the sample 3 to be tested from the temporary storage mechanism 30 to the detection mechanism 70. Exemplarily, the transfer mechanism 60 can include a pickup module and a transfer module. The pickup module can pick up the sample 3 to be tested from the temporary storage mechanism 30. The transfer module can transfer the pickup module at least between the detection mechanism 70 and the temporary storage mechanism 30 to drive the component to be tested from the temporary storage mechanism 30 to the detection mechanism 70. The pickup module can be, but is not limited to, a suction cup, a gripper, etc. The transfer module can be, but is not limited to, a conveyor belt, a conveyor chain, etc. Understandably, by integrating the transfer mechanism 60 and the inspection mechanism 70 into the electrode cutting system 1, there is no need to set up an additional independent electrode inspection station. For example, operators can perform multiple processes such as electrode cutting and electrode inspection through a single station corresponding to the electrode cutting system 1, thereby improving the integration level of the electrode cutting system 1. Thus, by transferring the sample 3 to be tested from the temporary storage mechanism 30 to the inspection mechanism 70 through the transfer mechanism 60, the automation level of the electrode cutting system 1 is improved. At the same time, by integrating the transfer mechanism 60 and the inspection mechanism 70 into the electrode cutting system 1, the integration level of the electrode cutting system 1 is improved, and production efficiency is increased.

[0068] In some embodiments, the detection mechanism 70 includes a weight detector 71 and a moisture detector 72. It is understood that the weight detector 71 can be used to detect the weight of the sample 3 to be tested, and the moisture detector 72 can be used to detect the water content of the sample 3. The weight detector 71 may include, but is not limited to, an electronic scale, etc., and the moisture detector 72 may include, but is not limited to, a moisture meter, etc. It is understood that the transfer mechanism 60 can transfer the sample 3 to be tested to the weight detector 71 and the moisture detector 72 respectively for testing. The transfer mechanism 60 can also receive the sample 3 from the weight detector 71 and the moisture detector 72. Exemplarily, the transfer mechanism 60 can release the sample 3 to the weight detector 71. After the weight detector 71 completes the weight detection of the sample 3, the transfer mechanism 60 can receive the sample 3 from the weight detector 71 again. In some application scenarios, the weight detector 71 may include a weight detection unit and a protective cover. The weight detection unit is used to perform weight detection on the sample 3. During the weight detection process, the protective cover can be used to cover the sample 3 to isolate the internal and external spaces of the protective cover, thereby reducing the influence of external airflow on the weight detection results. The moisture detector 72 may include a moisture detection unit and a protective cover. The moisture detection unit is used to detect the moisture content of the sample 3 to be tested. During the moisture detection process, the protective cover can be placed over the sample 3 to isolate the internal and external spaces of the protective cover, thereby reducing the influence of external airflow on the moisture detection results and improving the accuracy of the detection results. Thus, the weight of the sample 3 to be tested can be detected by the weight detector 71, and the moisture content of the sample 3 to be tested by the moisture detector 72, so as to detect the sample 3 from multiple aspects, improve the accuracy of the detection of the sample 3 to be tested, and at the same time improve the integration of the electrode cutting system 1 and improve the detection efficiency.

[0069] In some embodiments, the temporary storage mechanism 30 includes a movable temporary storage box 31, which moves between a first position p1 and a second position p2 different from the first position p1. The movable temporary storage box 31 is used to receive the sample to be tested 3 at the first position p1, and the transfer mechanism 60 is used to receive the sample to be tested 3 at the second position p2. The movable temporary storage box 31 can form a receiving cavity, thereby receiving and temporarily storing the sample to be tested 3 through the receiving cavity. Exemplarily, at the first position p1, the movable temporary storage box 31 can be set corresponding to the cutting position 11. When the laser cutting mechanism 20 cuts the electrode 2 and completely separates the sample to be tested 3 from the electrode 2, the sample to be tested 3 can fall into the movable temporary storage box 31 under the action of gravity. At the second position p2, the movable storage box 31 can be correspondingly set with the transfer mechanism 60 so that the transfer mechanism 60 can receive the sample 3 to be tested from the movable storage box 31. For example, when the transfer mechanism 60 includes a pickup module and a transfer module, at the second position p2, the movable storage box 31 can be correspondingly set with the pickup module of the transfer mechanism 60, thereby facilitating the pickup module to receive the sample 3 to be tested from the movable storage box 31. In some application scenarios, the movable storage box 31 can be driven to move between the first position p1 and the second position p2 by a driving device. For example, the movable storage box 31 can be connected to a guide rail, which can extend between the first position p1 and the second position p2. The driving device can drive the movable storage box 31 to move along the guide rail between the first position p1 and the second position p2, wherein the driving device can include, but is not limited to, a drive motor, a drive cylinder, etc. Therefore, the sample to be tested 3 can be transferred between the first position p1 and the second position p2 by moving the temporary storage box 31, which improves the automation level of the temporary storage mechanism 30, reduces the difficulty for the transfer mechanism 60 to obtain the sample to be tested 3, and improves production efficiency.

[0070] In some embodiments, the transfer mechanism 60 includes a transfer bracket 61 and a transfer body 62. The transfer bracket 61 extends along the transfer direction x3, and the transfer body 62 is slidably connected to the transfer bracket 61. The transfer body 62 moves relative to the transfer bracket 61 along the transfer direction x3. A second position p2 is located in the transfer direction x3. The transfer body 62 is used to transfer the sample 3 to be tested. The transfer bracket 61 can provide support for the transfer body 62 and guide the transfer body 62 to move along the transfer direction x3. The transfer bracket 61 may include, but is not limited to, guide rails, guide chains, etc. The transfer body 62 may include, but is not limited to, suction cups, grippers, etc. Since the second position p2 is located in the transfer direction x3, it can be understood that the transfer body 62 can receive the sample 3 to be tested from the moving storage box 31 at the second position p2 and drive the sample 3 to be tested to move in the transfer direction x3 so that the sample 3 to be tested is transferred to the detection mechanism 70. Therefore, the sample to be tested 3 can be transferred in the transfer direction x3 by sliding the transfer body 62 on the transfer bracket 61 along the transfer direction x3, which improves the automation level of the transfer mechanism 60, while the structure is simple and saves costs.

[0071] In some embodiments, the detection mechanism 70 includes a weight detector 71 and a moisture detector 72, which are sequentially arranged in the transfer direction x3, with the weight detector 71 being closer to the second position p2 than the moisture detector 72. It is understood that during the movement of the transfer body 62 in the transfer direction x3, the transfer body 62 may pass through the weight detector 71 and the moisture detector 72 sequentially. Since the weight detector 71 is closer to the second position p2 than the moisture detector 72, after the transfer body 62 receives the sample 3 from the second position p2 and moves along the transfer direction x3, the transfer body 62 will first pass through the weight detector 71 and then the moisture detector 72. It should be noted that if the moisture content of the sample 3 is measured before the weight measurement, the accuracy of the weight measurement result may be affected. Specifically, after receiving the sample 3 to be tested from the second position p2, the transfer body 62 moves along the transfer direction x3. The transfer body 62 first passes through the weight detector 71 and releases the sample 3 to the weight detector 71 for weight detection. After the weight detection of the sample 3 is completed, the transfer body 62 receives the sample 3 from the weight detector 71 and continues to move along the transfer direction x3. Then, the transfer body 62 passes through the moisture detector 72 and releases the sample 3 to the moisture detector 72 for moisture detection. After the moisture detection of the sample 3 is completed, the transfer body 62 can receive the sample 3 from the moisture detector 72. It can be understood that during the process of the transfer body 62 moving the sample 3 along the transfer direction x3, the transfer body 62 can ensure that the sample 3 passes through the weight detector 71 and the moisture detector 72 sequentially for detection without returning, effectively saving the transfer distance. Therefore, by making the weight detector 71 closer to the second position p2 relative to the moisture detector 72, the transfer body 62 can prioritize the weight detection of the sample 3 to be tested through the weight detector 71 during the transfer of the sample 3 along the transfer direction x3, which saves the transfer distance and reduces the risk of interference with the weight detection result caused by prioritizing moisture detection, thereby improving the reliability of the laser cutting mechanism 20.

[0072] In some embodiments, the electrode cutting system 1 further includes a sample recovery mechanism 80. The sample recovery mechanism 80 is located in the transfer direction x3, with the moisture detector 72 positioned closer to the sample recovery mechanism 80 than the weight detector 71. The transfer body 62 is used to transfer the sample to be tested 3 to the sample recovery mechanism 80. The sample recovery mechanism 80 can perform recovery processing on the sample to be tested 3. The sample recovery mechanism 80 can be, but is not limited to, a recovery box, recovery container, etc., which can be used to accommodate and store the sample to be tested 3 after testing. The moisture detector 72 being closer to the sample recovery mechanism 80 than the weight detector 71 facilitates faster transfer of the sample to be tested 3 to the sample recovery mechanism 80 by the transfer body 62 after moisture detection. In some application scenarios, the second position p2, weight detector 71, moisture detector 72, and sample recovery mechanism 80 are sequentially arranged in the transfer direction x3. This means that during the process of the transfer body 62 moving the sample to be tested 3 along the transfer direction x3, the transfer body 62 can sequentially perform weight detection, moisture detection, and recovery processing on the sample to be tested 3 without needing to return, effectively saving transfer distance. Therefore, by setting the moisture detector 72 closer to the sample recovery mechanism 80 relative to the weight detector 71 in the transfer direction x3, it is beneficial for the transfer body 62 to continue transferring the sample to be tested 3 to the sample recovery mechanism 80 along the transfer direction x3 after the moisture detection of the sample to be tested 3, thus saving the transfer distance and improving the transfer efficiency.

[0073] In some embodiments, the electrode cutting system 1 includes an operating table 90 and a controller 91. The conveying mechanism 10, the laser cutting mechanism 20, the temporary storage mechanism 30, and the controller 91 are supported on the operating table 90. The operating table 90 can be used to provide fixation and support for the conveying mechanism 10, the laser cutting mechanism 20, the temporary storage mechanism 30, and the controller 91. The material of the operating table 90 may include, but is not limited to, marble, metal, etc. The controller 91 can be used to control the actions of, but is not limited to, the conveying mechanism 10, the laser cutting mechanism 20, and the temporary storage mechanism 30. The operator can control the specific working state of the electrode cutting system 1 through the operating table 90 and the controller 91. In some application scenarios, the electrode cutting system 1 also includes a detection mechanism 70 and a transfer mechanism 60. The controller 91 can also be used to control the actions of the detection mechanism 70 and the transfer mechanism 60. Therefore, the operating table 90 can provide fixation and support for the conveying mechanism 10, the laser cutting mechanism 20, the temporary storage mechanism 30 and the controller 91, thereby improving the cutting stability. Furthermore, by integrating the conveying mechanism 10, the laser cutting mechanism 20, the temporary storage mechanism 30 and the controller 91 onto the operating table 90, the integration of the electrode cutting system 1 is greatly improved. At the same time, the controller 91 can control the actions of the conveying mechanism 10, the laser cutting mechanism 20 and the temporary storage mechanism 30, thereby improving the flexibility of the electrode cutting system 1.

[0074] In some application scenarios, the electrode cutting system 1 may include a host computer, which can communicate with the conveying mechanism 10, the laser cutting mechanism 20, the temporary storage mechanism 30, etc. The host computer can communicate directly with the conveying mechanism 10, the laser cutting mechanism 20, the temporary storage mechanism 30, etc., or indirectly through the controller 91. The host computer can record data acquired by the conveying mechanism 10, the laser cutting mechanism 20, the temporary storage mechanism 30, etc., and can perform action planning based on the acquired data. For example, the host computer can record the status information of the electrode 2 acquired by the conveying mechanism 10, and can perform cutting planning for the laser cutting mechanism 20 based on the acquired status information. In some application scenarios, the electrode cutting system 1 also includes a second sensor 100. The host computer can also record image information of the sample 3 to be tested collected by the second sensor 100, and can perform processing planning for the sample 3 to be tested based on the acquired image information. In some application scenarios, the electrode cutting system 1 also includes a detection mechanism 70, and the host computer can acquire and record the detection results of the sample 3 to be tested detected by the detection mechanism 70. Thus, the automation and integration of the electrode cutting system 1 can be improved through the host computer.

[0075] In some embodiments, the electrode cutting system 1 further includes a detection mechanism 70. The operating table 90 includes a first platform 92 and a second platform 93 spaced apart. The conveying mechanism 10, the laser cutting mechanism 20, the temporary storage mechanism 30, and the controller 91 are supported on the first platform 92, and the detection mechanism 70 is supported on the second platform 93. The detection mechanism 70 may include, but is not limited to, a weight detector 71 and a moisture detector 72, etc. It should be noted that the conveying mechanism 10, the laser cutting mechanism 20, and the temporary storage mechanism 30 will generate a certain degree of vibration during their operation. For example, the conveying mechanism 10 vibrates to a certain extent during the conveying of the electrode 2, and the laser cutting mechanism 20 vibrates to a certain extent during the cutting of the electrode 2. This vibration will be transmitted to the first platform 92. It is understood that the detection mechanism 70 has high stability requirements during the detection of the sample 3. If the vibration is transmitted to the detection mechanism 70, it will easily interfere with the detection results, thereby affecting the accuracy of the detection results. By spaced the first platform 92 and the second platform 93, this vibration cannot be transmitted from the first platform 92 to the second platform 93, which helps the second platform 93 to remain stationary and stable. The second platform 93 can be made of materials including, but not limited to, marble and alloys. In some applications, the second platform 93 includes an upper part positioned upstream of gravity direction x2 and a lower part positioned downstream of gravity direction x2. The center of gravity of the second platform 93 can be located in the lower part. For example, the lower part of the second platform 93 can be made of carbon steel, and the upper part can be made of marble. This facilitates the installation of the detection mechanism 70 through the marble upper part, while the carbon steel lower part lowers the center of gravity of the second platform 93, improving its stability. In some applications, when observing the operating table 90 along gravity direction x1, the first platform 92 can be concave, and the second platform 93 can be located in the concave part of the first platform 92 and spaced apart from it, thereby improving space utilization. Therefore, by separating the detection mechanism 70 from the conveying mechanism 10, the laser cutting mechanism 20, the temporary storage mechanism 30, and the controller 91 through the first platform 92 and the second platform 93, the risk of vibrations from the conveying mechanism 10, the laser cutting mechanism 20, the temporary storage mechanism 30, and other components from interfering with the detection results of the detection mechanism 70 is reduced, thereby improving the stability and reliability of the detection mechanism 70. In summary, the electrode cutting system 1 provided in this application includes a conveying mechanism 10, a laser cutting mechanism 20, and a temporary storage mechanism 30. The conveying mechanism 10 conveys the electrode 2 to the cutting position 11 along the conveying direction x1; the laser cutting mechanism 20 is used to cut the electrode 2 at the cutting position 11 to form the sample to be tested 3; the temporary storage mechanism 30 is located downstream of the cutting position 11 in the gravity direction x2, and is used to receive the sample to be tested 3. The conveying direction x1 and the gravity direction x2 intersect.Therefore, the electrode sheet 2 is conveyed to the cutting position 11 by the conveying mechanism 10, so that the laser cutting mechanism 20 can cut the electrode sheet 2 at the cutting position 11 to form the test sample 3, thereby realizing automated cutting of the electrode sheet 2 and improving the consistency of the test sample 3. The test sample 3 is received by the temporary storage mechanism 30, which facilitates subsequent operations such as testing of the test sample 3 and improves production efficiency. At the same time, the temporary storage mechanism 30 is located downstream of the cutting position 11 in the gravity direction x2, which is conducive to making full use of gravity to collect the test sample 3, simplifying the product structure and reducing the product manufacturing cost. Compared with other electrode cutting systems, the electrode cutting system 1 provided in this application has a higher degree of automation and cutting efficiency, and the cut test sample 3 has better consistency.
