Description

Technical Field

[0001] This invention relates to the field of lithium battery testing, and more specifically, to a lithium battery positioning and testing system and equipment. Background Technology

[0002] In the production process of lithium batteries, formation testing, capacity testing, and open-circuit voltage (OCV) testing are key steps to ensure battery quality, capacity consistency, and safety. These testing steps not only require accurate measurement of various performance indicators of the battery, but also rely on the accurate docking of probes with the positive and negative electrodes of the lithium battery in the testing equipment to ensure the reliability and accuracy of the test data. However, existing lithium battery testing equipment still faces many challenges in the positioning of the probes in contact with the battery. First, due to slight deviations in the production process or slight changes in the shape of the battery, the contact position between the probes and the positive and negative electrodes of the battery may be offset, which directly affects the accuracy and precision of the test results. Especially in high-speed, high-volume production scenarios, even small contact deviations may be amplified and have a significant impact on the overall test results.

[0003] For example, the Chinese invention patent (application number: CN202010135304.4) discloses "A cylindrical lithium battery probe position detection fixture, detection system and detection method," which states that during formation testing, capacity testing, and OCV testing, the good contact between the probe and the positive and negative electrodes of the lithium battery directly affects the accuracy and precision of the test results. Furthermore, probe misalignment can cause the probe to contact the aluminum casing of the battery, resulting in a short circuit and posing a potential risk of battery explosion. Therefore, the probe position needs to be precisely located. This patent demonstrates the deficiencies in the existing technology.

[0004] Therefore, we have made improvements to this and proposed a lithium battery positioning and detection system and equipment. Summary of the Invention

[0005] The purpose of this invention is to address the potential risk of battery explosion caused by the misalignment of existing detection probes, which can lead to short circuits when the probe comes into contact with the aluminum casing of the battery.

[0006] To achieve the above-mentioned objectives, the present invention provides a lithium battery positioning and detection system and device to improve the aforementioned problems.

[0007] The application is as follows:

[0008] A lithium battery positioning and detection system includes a positioning module for acquiring and recording the precise location information of each lithium battery in a specific area in real time;

[0009] The detection module integrates multiple sensors to detect the state parameters of the lithium battery, including voltage, current, temperature and internal resistance.

[0010] The data processing unit receives data from the positioning module and the detection module, analyzes and processes it, and determines the health status and location rationality of the lithium battery based on a preset algorithm.

[0011] The communication module supports wireless or wired communication methods to transmit processed data to a remote monitoring center or user terminal.

[0012] The alarm module automatically triggers an alarm signal when it detects an abnormal lithium battery status or a deviation from the preset area.

[0013] The rejection module removes the abnormal lithium battery from the lithium battery pack when it detects an abnormal state of the lithium battery.

[0014] The positioning module acquires the lithium battery's location information in real time, the detection module collects the lithium battery's status parameters, and the collected data is sent to the data processing unit for analysis and processing. Then, based on the processing results, the health status and location rationality of the lithium battery are judged. If an abnormality is found, an alarm signal is issued through the alarm module, and the abnormal lithium battery is removed separately through the rejection module.

[0015] As a preferred technical solution of this application, the detection module includes a voltage detection unit, which uses a high-precision ADC chip to monitor the terminal voltage at both ends of the lithium battery in real time.

[0016] The current detection unit uses a Hall sensor to convert the current signal into a voltage signal and detects the magnitude of the voltage signal.

[0017] The temperature detection unit integrates a thermistor or digital temperature sensor to monitor the temperature of the lithium battery in real time when it is powered on.

[0023] As a preferred technical solution of this application, the alarm module includes an audible and visual alarm and a remote notification function. When an abnormal situation is detected, it can immediately issue a local alarm signal and send alarm information to a remote monitoring center or user terminal through the communication module.

[0024] A lithium battery positioning and detection device includes an operating platform and a lithium battery pack. A control screen is fixedly installed on the top of the operating platform, and electric cylinders are fixedly installed on both sides of the top of the operating platform. A slot is opened in the middle of the top of the operating platform, and the lithium battery pack is placed inside the slot. A positioning and detection component is provided in the middle of the top of the operating platform.

[0025] The positioning detection component includes a lifting frame and a fixed ring. The fixed ring array is installed in the middle of the lifting frame. A rotating ring is rotatably installed in the middle of the fixed ring. Four sets of hinge blocks are fixedly installed at equal angles on the inner side of the rotating ring. A support plate is movably hinged to the bottom of each set of hinge blocks. A sleeve is fixedly connected to the bottom of each of the four support plates. A telescopic plate is slidably fitted into the bottom of the inner cavity of each of the four sleeves. A detection head is fixedly installed at the bottom of the telescopic plate. A support spring is fixedly installed in the middle of the top of the detection head. The top of the support spring is fixedly connected to the top of the inner cavity of the sleeve. The four detection heads are arranged in a circular array.

[0026] The top of the rotating ring is provided with a fixing component, which includes a suspension. The bottom of the suspension is fixedly connected to the outer side of the top of the rotating ring. The middle of the suspension is provided with a mounting groove. The side of the mounting groove is provided with four telescopic grooves at equal angles. A top plate is slidably fitted inside the telescopic groove. An electromagnet is vertically slidably installed inside the mounting groove. A limit block is fixedly installed at the inner end of the top plate. The bottom of the electromagnet is attached to the inclined surface of the limit block. The outer end of the top plate is supported on the top inner side of the support plate.

[0027] As a preferred technical solution of this application, the bottom of the electromagnet is conical and matches the top inclined surface of the limiting block. A top rod is fixedly installed at the bottom of the electromagnet, and the bottom end of the top rod extends downward and is level with the middle height of the detection head when it retracts.

[0028] As a preferred technical solution of this application, the bottom of the mounting groove is fixedly connected to a base, a reset spring is fixedly installed at the bottom of the inner cavity of the base, and the top of the reset spring is fixedly connected to the bottom of the electromagnet to support the electromagnet.

[0029] As a preferred technical solution of this application, the fixed ring is a stator, the rotating ring is a rotor, the rotating ring is rotatably installed inside the fixed ring, and the fixed ring is driven to rotate the rotating ring by electromagnetic drive.

[0030] As a preferred technical solution of this application, the bottom of the detection head is frosted, the inner side of the detection head is made of rubber, the detection head moves vertically downward and directly contacts the electrode post at the top of the lithium battery, and the detection head opens outward to clamp the electrode post of the lithium battery.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0032] In the scheme of this application:

[0033] 1. To address the problem in existing technologies where probe misalignment can lead to short circuits caused by contact between the probe and the aluminum casing of the battery, potentially posing a risk of battery explosion, this application's positioning module acquires the lithium battery's location information in real time, uses the detection module to collect the lithium battery's state parameters, sends the collected data to the data processing unit for analysis, and then judges the lithium battery's health status and location rationality based on the processing results. If an abnormality is detected, an alarm signal is issued through the alarm module, and the abnormal lithium battery is removed separately through the rejection module. This achieves precise positioning, prevents the probe from contacting the battery's aluminum casing, and allows for more comprehensive detection of the lithium battery.

[0034] 2. To address the problem in existing technologies where probe misalignment can lead to short circuits due to contact between the probe and the aluminum casing of the battery, this application employs a ring-shaped arrangement of four detection heads that completely enclose the arc edge at the top of the electrode post. This replaces traditional probe detection with arc-shaped contact, and a support spring provides elastic support for the detection heads, creating pressure between the detection heads and the electrode posts. This ensures more comprehensive contact between the detection heads and the electrode posts and prevents partial contact issues common in traditional probes. The simultaneous enclosing detection of the arc edge at the top of the electrode post by all four detection heads avoids localized poor contact, thus protecting the lithium battery during detection and making the detection more accurate.

[0035] 3. The top of the support plate is supported by a fixed component, and the rotation of the support plate is controlled. This keeps the support plate vertical, allowing the detection head to be pulled to detect the lithium battery. When a problematic lithium battery is found, the power to the electromagnet at that location is cut off, causing the detection head to rotate outward and move downward. The inner side of the detection head contacts the top electrode post of the lithium battery. Then, a small current is applied to the electromagnet again, causing the detection head to move inward and clamp the electrode post. The lifting frame is moved upward by the electric cylinder. After the lithium battery pack is removed, a strong current is applied to the electromagnet to increase its magnetism, causing the electromagnet to sink quickly. The lithium battery is then pushed out by the push rod at the bottom of the electromagnet. This achieves the positioning and detection of the lithium battery. At the same time, through structural transformation, problematic lithium batteries can be selected and removed, solving the problem of the need for manual secondary selection and removal when a problematic lithium battery is detected in the existing technology, which increases labor costs.

[0036] 4. By controlling the bottom of the detection head to make slight contact with the top of the lithium battery electrode post through the electric cylinder, the fixing ring rotates through electromagnetic drive, thereby allowing the abrasive part at the bottom of the detection head to polish the top of the electrode post, removing the slight burrs around the top of the electrode post, so that the detection head can better conduct and connect with the lithium battery. This removes burrs and impurities from the top of the lithium battery, solving the problem in the prior art where impurities on the electrode post affect the detection of lithium batteries.

[0051] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0052] As described in the background section, the misalignment of the detection probe can cause the probe to come into contact with the aluminum casing of the battery, resulting in a short circuit and posing a potential risk of battery explosion. Therefore, the positioning accuracy of the probe needs to be further improved.

[0053] To address this technical problem, the present invention provides a lithium battery positioning and detection system and equipment, which is applied to the detection of lithium batteries.

[0054] For details, please refer to Figure 1 The lithium battery positioning and detection system specifically includes:

[0055] The positioning module is used to acquire and record the precise location information of each lithium battery in a specific area in real time;

[0056] The detection module integrates multiple sensors to detect the state parameters of the lithium battery, including voltage, current, temperature and internal resistance.

[0057] The data processing unit receives data from the positioning module and the detection module, analyzes and processes it, and determines the health status and location rationality of the lithium battery based on a preset algorithm.

[0058] The communication module supports wireless or wired communication methods to transmit processed data to a remote monitoring center or user terminal.

[0059] The alarm module automatically triggers an alarm signal when it detects an abnormal lithium battery status or a deviation from the preset area.

[0060] The rejection module removes the abnormal lithium battery from the lithium battery pack when it detects an abnormal state of the lithium battery.

[0061] The positioning module acquires the lithium battery's location information in real time, the detection module collects the lithium battery's status parameters, and the collected data is sent to the data processing unit for analysis and processing. Then, based on the processing results, the health status and location rationality of the lithium battery are judged. If an abnormality is found, an alarm signal is issued through the alarm module, and the abnormal lithium battery is removed separately through the rejection module.

[0062] This invention provides a lithium battery positioning and detection system. To address the problem in existing technologies where probe misalignment can lead to short circuits due to contact between the probe and the battery's outer aluminum packaging, potentially causing battery explosion, this application's positioning module acquires real-time lithium battery location information. The detection module collects lithium battery status parameters, and the collected data is sent to a data processing unit for analysis. Based on the processing results, the system determines the lithium battery's health status and the rationality of its location. If an abnormality is detected, an alarm signal is issued via an alarm module, and the abnormal lithium battery is isolated using an exclusion module. This achieves precise positioning, preventing the probe from contacting the battery's aluminum packaging and enabling more comprehensive lithium battery detection.

[0063] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0064] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0065] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0066] Example 1, please refer to Figure 1 A lithium battery positioning and detection system, wherein the detection module includes: a voltage detection unit, which uses a high-precision ADC chip to monitor the terminal voltage of the lithium battery in real time; a current detection unit, which uses a Hall sensor to convert the current signal into a voltage signal and detects the magnitude of the voltage signal; a temperature detection unit, which integrates a thermistor or a digital temperature sensor to monitor the temperature of the lithium battery in real time when it is powered on; and an internal resistance detection unit, which calculates the internal resistance of the lithium battery by controlling the activation and deactivation of a power relay using the potential difference method.

[0067] Please refer to Figure 1 A lithium battery positioning and detection system includes a data processing unit comprising: a data analysis module for preprocessing, filtering, and feature extraction of received data; a status assessment module for assessing the health status of the lithium battery based on a preset algorithm; a location determination module for determining whether the lithium battery is located within a preset safe or working area based on positioning information; a communication module supporting multiple communication protocols, including Wi-Fi, Bluetooth, LoRa, and NB-IoT, to ensure the reliability and flexibility of data transmission; and an alarm module including an audible and visual alarm and remote notification function, capable of immediately issuing a local alarm signal and sending alarm information to a remote monitoring center or user terminal via the communication module when an abnormality is detected.

[0068] Example 2, a lithium battery positioning and detection device, specifically, as follows: Figures 2-10 As shown, it includes an operating platform 1 and a lithium battery pack 103. A control screen 102 is fixedly installed on the top of the operating platform 1. Electric cylinders 105 are fixedly installed on both sides of the top of the operating platform 1. A slot 101 is opened in the middle of the top of the operating platform 1. The lithium battery pack 103 is placed inside the slot 101. A positioning detection component 2 is provided in the middle of the top of the operating platform 1.

[0069] The positioning detection component 2 includes a lifting frame 201 and a fixed ring 202. The fixed ring 202 is arrayed and installed in the middle of the lifting frame 201. A rotating ring 203 is rotatably installed in the middle of the fixed ring 202. Four sets of hinge blocks 204 are fixedly installed at equal angles on the inner side of the rotating ring 203. A support plate 205 is movably hinged to the bottom of each set of hinge blocks 204. A sleeve 206 is fixedly connected to the bottom of each of the four support plates 205. A telescopic plate 208 is slidably fitted on the bottom of the inner cavity of each of the four sleeves 206. A detection head 207 is fixedly installed on the bottom of the telescopic plate 208. A support spring 209 is fixedly installed in the middle of the top of the detection head 207. The top of the support spring 209 is fixedly connected to the top of the inner cavity of the sleeve 206. The four detection heads 207 are arranged in a circular array.

[0070] The top of the rotating ring 203 is provided with a fixing component 3, which includes a suspension 301. The bottom of the suspension 301 is fixedly connected to the outer side of the top of the rotating ring 203. The middle part of the suspension 301 is provided with a mounting groove 302. The side of the mounting groove 302 is provided with four telescopic grooves 303 at equal angles. The top plate 304 is slidably sleeved inside the telescopic groove 303. The electromagnet 306 is vertically slidably installed inside the mounting groove 302. The inner end of the top plate 304 is fixedly installed with a limit block 305. The bottom of the electromagnet 306 is attached to the inclined surface of the limit block 305. The outer end of the top plate 304 is supported on the top inner side of the support plate 205.

[0071] Four detection heads 207 are arranged in a ring array, simultaneously pressing each head onto the top of the outer circumference of the lithium battery electrode post. The heads are slightly opened outwards to make conductive contact with the four edges of the top of the lithium battery electrode post. This ring arrangement, compared to traditional probes, provides more precise positioning and avoids the short circuit problem caused by contact between the probe and the battery's outer aluminum casing. During the process of the lifting frame 201 pulling the detection heads 207 down to press them onto the top of the lithium battery electrode post, controlled by the electric cylinder 105, the support spring 209 provides elastic support to the detection heads 207. After contacting the top of the lithium battery, the probe 207 is continuously squeezed and compressed, creating pressure between it and the top of the lithium battery. This avoids the situation where traditional probes only make slight contact with the electrode posts on the top of the lithium battery, resulting in some probes not making contact with the electrode posts due to height differences, thus creating detection loopholes. The four circularly arranged probes 207 are connected to the four sides of the top of the lithium battery electrode posts, allowing for thorough detection of the electrode posts and preventing poor contact in certain areas. If any probe 207 fails to connect and conduct with the lithium battery, it proves that there is a problem with poor contact of the lithium battery electrode posts.

[0072] Furthermore, such as Figure 8 and Figure 9As shown, the bottom of the electromagnet 306 is conical and matches the top slope of the limiting block 305. During its downward movement, the conical electromagnet 306 presses against the top of the limiting block 305, causing the limiting block 305 to press the top plate 304 outward. This allows the outer end of the top plate 304 to support the inner top of the support plate 205, ensuring that the detection head 207 at the bottom of the support plate 205 remains vertical and can stably detect contact with the lithium battery electrode posts. A top rod 307 is fixedly installed at the bottom of the electromagnet 306. The top rod 307 extends downwards to the same height as the middle of the detection head 207 when it is retracted. A base 308 is fixedly connected to the bottom of the mounting groove 302. A return spring 309 is fixedly installed at the bottom of the inner cavity of the base 308. The top of the return spring 309 is fixedly connected to the bottom of the electromagnet 306 to support it. If a problem is found with the lithium battery during testing, the electromagnet 306 will be de-energized and demagnetized. Under the elastic support of the return spring 309, the electromagnet 306 will automatically move upwards. At this time, the inner side of the top of the support plate 205 loses its... The support plate 205 is supported, and the bottom inner side of the detection head 207 is compressed, so the detection head 207 will move outward and extend outward under the support of the support spring 209, causing the top of the support plate 205 to move inward. At this time, the electromagnet 306 is energized again. The magnetic strength of the electromagnet 306 is controlled by controlling the magnitude of the current in the electromagnet 306, causing the electromagnet 306 to move downward and the limiting block 305 to move outward. This causes the top plate 304 to press the top inner side of the support plate 205 outward, and the force is just enough to make the four detection heads 207 move outward. The inner side of 07 clamps the top of the lithium battery electrode post. After clamping, the lifting frame 201 is raised by the electric cylinder 105 to remove the lithium battery pack 103 from the inside of the slot 101. At this time, the current inside the electromagnet 306 is increased, thereby strengthening the magnetism of the electromagnet 306, which causes the electromagnet 306 to move downward quickly. The top rod 307 at the bottom of the electromagnet 306 impacts the top of the lithium battery, causing the lithium battery to fall into the bottom operating platform 1, thereby removing the problematic lithium battery.

[0073] Example 3 further optimizes the lithium battery positioning and detection device provided in Example 2, specifically, as follows: Figure 2 and Figure 7As shown, the fixed ring 202 is the stator, and the rotating ring 203 is the rotor. The rotating ring 203 is rotatably installed inside the fixed ring 202. The fixed ring 202 drives the rotating ring 203 to rotate electromagnetically. The bottom of the detection head 207 is frosted. Before detection, the bottom of the detection head 207 is first slightly contacted with the top of the lithium battery electrode post. At this time, the fixed ring 202 drives the rotating ring 203 to rotate, so that the frosted part at the bottom of the detection head 207 can polish the top of the electrode post and remove the slight burrs around the top of the electrode post, so that the detection head 207 can better conduct and connect with the lithium battery. The arc-shaped position at the bottom of the detection head 207 connects and conducts with the electrode post at the top of the lithium battery. The inner side of the detection head 207 is made of rubber, which can clamp the electrode post of the lithium battery to prevent the lithium battery from slipping. The detection head 207 moves vertically downward and directly contacts the electrode post at the top of the lithium battery. The detection head 207 opens outward to clamp the electrode post of the lithium battery.

[0074] The lithium battery positioning and detection system and equipment provided by this invention are used as follows:

[0075] The lithium battery pack 103 is placed into the slot 101 opened at the top of the operating platform 1. Then, the lifting frame 201 is lowered by the electric cylinder 105 so that the frosted part at the bottom of the detection head 207 makes slight contact with the arc at the top of the electrode post. Then, the rotating ring 203 is driven to rotate by the electromagnetic action of the fixing ring 202 so that the frosted part at the bottom of the detection head 207 removes impurities and burrs on the arc of the electrode post.

[0076] Then, the detection head 207 is further lowered by the electric cylinder 105, causing the detection head 207 to compress the support spring 209 and make close contact with the electrode post at the top of the lithium battery 104. Under pressure, it slightly opens outward, allowing the arc-shaped part of the inner side of the detection head 207 to contact the arc-shaped part of the lithium battery electrode post. At this time, the four detection heads 207 detect the entire circumference of the electrode post to prevent poor contact in certain areas. After the detection is completed, the electromagnet 306 at the top of the lithium battery with problems is immediately de-energized. At this time, the electromagnet 306 will automatically move upward under the elastic support of the return spring 309, causing the inner side of the support plate 205 at the top of the detection head 207 to lose support. At this time, the support plate 205 will push the hinge block 204 inward. The detector 207 is pressed from the side, causing its bottom to unfold outwards. The inner rubber part of the detector 207 then wraps around and clamps the side of the lithium battery electrode post. At this time, a slight current is input to the electromagnet 306, causing it to move downwards and the top plate 304 to move outwards. The detector 207 then clamps the top of the electrode post. After clamping, the lifting frame 201 is moved upwards by the electric cylinder 105, and the lithium battery pack 103 is then removed from the slot 101. The current to the electromagnet 306 is increased again, causing it to sink rapidly under strong magnetic attraction. The top rod 307 then pushes the lithium battery downwards into the slot 101 at the bottom and into the operating platform 1, thus completing the removal of the problematic lithium battery.
