[0002] In the production process of lithium batteries, formation test, capacity test and open circuit voltage (OCV) test are key links to ensure battery quality, capacity consistency and safety. These test links not only require precise measurement of various battery performance indicators, but also rely on the accurate docking of the probes in the test equipment with the positive and negative electrodes of the lithium battery to ensure the reliability and accuracy of the test data. However, the existing lithium battery testing equipment still faces many challenges in the positioning of the contact between the probes and the battery. First, due to slight deviations in the production process or slight changes in the battery shape, the contact position between the probes and the positive and negative electrodes of the battery may be offset, which directly affects the precision and accuracy of the test results. Especially in high-speed, mass-production scenarios, slight contact deviations may be magnified, which has 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 tooling, detection system and detection method". Its specification discloses: During the formation test, capacity test and OCV test, the good contact between the probe and the positive and negative electrodes of the lithium battery directly affects the precision and accuracy of the test results. In addition, the deviation of the detection probe will cause the probe to contact the aluminum skin of the battery outer packaging and cause a short circuit, which poses a potential risk of battery explosion. Therefore, the position of the detection probe needs to be accurately located; the above patent can prove the defects of the existing technology.

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

The bottom of the suspension is fixedly connected to the outer side of the top of the rotating ring. A mounting groove is provided in the middle of the suspension. Four telescopic grooves are provided at equal angles on the side of the mounting groove. A top plate is provided inside the telescopic groove. A through electromagnet is vertically slidably installed inside the mounting groove. A limit block is fixedly installed on the inner end of the top plate. The bottom of the through electromagnet is attached to the inclined surface of the limit block, and the outer end of the top plate is supported on the inner side of the top of the support plate.

[0013] As a preferred technical solution of the present application, the bottom of the electromagnet is conical and matched with the top slope of the limit block.

[0017] Compared with the prior art, the present invention has the following beneficial effects: In the scheme of this application: 1. In order to solve the problem in the prior art that the deviation of the detection probe may cause the probe to contact with the aluminum skin of the battery outer packaging and cause a short circuit, thereby posing a potential risk of battery explosion, the positioning module of the present application obtains the position information of the lithium battery in real time, uses the detection module to collect the state parameters of the lithium battery, sends the collected data to the data processing unit for analysis and processing, and then judges the health status and position rationality of the lithium battery according to the processing results. If an abnormality is found, an alarm signal is sent through the alarm module, and the abnormal lithium battery is taken out separately through the rejection module, thereby achieving precise positioning, so that the probe will not contact the aluminum skin of the battery packaging, and a more comprehensive detection of the lithium battery is performed; 2. In order to solve the problem in the prior art that the deviation of the detection probe may cause the probe to contact with the aluminum skin of the battery outer packaging and cause a short circuit, the present application changes the traditional probe detection to arc circle contact by setting four detection heads in a ring shape and completely wrapping contact with the arc edge of the top of the electrode column respectively, and adopts a support spring to elastically support the detection head, so that there is a certain pressure on the contact between the detection head and the electrode column, so that the detection head and the electrode column can be more fully contacted, and at the same time, it can also prevent the situation that some traditional probes have no contact.

The top of the support plate is supported by a fixed component, and the rotation of the support plate is controlled, so that the support plate can be kept in a vertical state and the detection head can be pulled to detect the lithium battery. When a lithium battery with a problem appears, the power supply of the electromagnet at that position is directly cut off, so that the detection head rotates outward and moves downward, and contacts the top electrode column of the lithium battery through the inner side of the detection head. Then, a small current is passed again in conjunction with the electromagnet to make the detection head move inward close to the electrode column to clamp it, and the lifting frame is controlled to move upward by the electric cylinder. After the lithium battery pack is taken out, a strong current is passed through the electromagnet to increase the magnetism of the electromagnet, so that the electromagnet sinks quickly, and the lithium battery is pushed out by the push rod at the bottom of the electromagnet, thereby realizing the positioning detection of the lithium battery. At the same time, the lithium battery with a problem can be selected and taken out through the structural conversion, which solves the problem that the existing technology needs to manually select and take out the lithium battery for a second time after the problem is detected, which increases the labor force. 4. The bottom of the detection head is controlled by the set electric cylinder to make slight contact with the top of the lithium battery electrode column. The fixed ring rotates through the electromagnetic drive rotating ring, so that the frosted part at the bottom of the detection head can grind the top of the electrode column and remove the slight burrs around the top of the electrode column, so that the detection head can be better connected with the lithium battery, and the burrs and impurities on the top of the lithium battery are removed, which solves the problem of the presence of debris on the electrode column affecting the detection of the lithium battery in the prior art.

[0025] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0026] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0029] Please refer to Figure 1 , a lithium battery positioning detection system, wherein the data processing unit includes: a data analysis module, which preprocesses, filters and extracts features of the received data; a status evaluation module, which evaluates the health status of the lithium battery based on a preset algorithm; a position judgment module, which judges whether the lithium battery is located in a preset safety or working area according to the positioning information; the communication module supports multiple communication protocols, including Wi-Fi, Bluetooth, LoRa, and NB-IoT, to ensure the reliability and flexibility of data transmission; the alarm module includes an audible and visual alarm and a remote notification function. When an abnormal situation is detected, a local alarm signal can be immediately issued and an alarm message can be sent to a remote monitoring center or a user terminal through the communication module.

[0030] Embodiment 2, a lithium battery positioning detection device, specifically, as Figure 2-Figure 10 As shown, it includes an operating platform 1 and a lithium battery pack 103, a control panel 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 card slot 101 is opened in the middle of the top of the operating platform 1, the lithium battery pack 103 is placed inside the card slot 101, and a positioning detection component 2 is provided in the middle of the top of the operating platform 1; The positioning detection component 2 includes a lifting frame 201 and a fixed ring 202. The fixed ring 202 is arrayed in the middle of the lifting frame 201. A rotating ring 203 is rotatably installed in the middle of the fixed ring 202. Four groups of hinge blocks 204 are fixedly installed at equal angles on the inner side of the rotating ring 203. The bottom of each group of hinge blocks 204 is movably hinged with a support plate 205. The bottoms of the four support plates 205 are fixedly connected with sleeves 206. The bottoms of the inner cavities of the four sleeves 206 are slidably sleeved with telescopic plates 208. A detection head 207 is fixedly installed at 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 ring array. A fixing assembly 3 is provided at the top of the rotating ring 203, and the fixing assembly 3 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. A mounting groove 302 is provided in the middle of the suspension 301. Four telescopic grooves 303 are provided at equal angles on the side of the mounting groove 302. A top plate 304 is provided inside the telescopic groove 303 for sliding sleeve. A through electromagnet 306 is vertically slidably installed inside the mounting groove 302. A limit block 305 is fixedly installed at the inner end of the top plate 304. The bottom of the through 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 inner side of the top of the support plate 205. The four detection heads 207 are arranged in a circular array to form a ring, and the four detection heads 207 are squeezed on the top of the outer circumference of the lithium battery electrode column at the same time, and the detection heads 207 are slightly opened outward to make conductive contact with the four side edges of the top of the lithium battery electrode column. Compared with the traditional probe, the circular arrangement makes the positioning more accurate, and there will be no problem of short circuit caused by contact between the probe and the aluminum skin of the battery outer packaging. When the electric cylinder 105 controls the lifting frame 201 to pull the detection head 207 down and press it to the top of the lithium battery electrode, the support spring 209 will elastically support the detection head 207. After contacting with the top of the lithium battery, it is continuously squeezed and compressed so that there is a certain pressure between the detection head 207 and the top of the lithium battery, avoiding the situation that the traditional probe can only slightly contact with the electrode column on the top of the lithium battery, which leads to a certain height difference in the local area, and then causes some probes to not contact the electrode column, resulting in detection loopholes. The four detection heads 207 arranged in a ring are connected to the four sides of the top of the lithium battery electrode column, which can fully detect the electrode column and prevent poor contact in some parts of the electrode column. Once one detection head 207 fails to connect to the lithium battery, it can be proved that the electrode column of the lithium battery has a poor contact problem.

[0031] Further, such as Figure 8 and Fig. 9As shown, the bottom of the electromagnet 306 is conical and matches the top inclined surface of the limit block 305. When the conical electromagnet 306 moves downward, it will squeeze the top of the limit block 305, so that the limit block 305 squeezes the top plate 304 outward, so that the outer end of the top plate 304 supports the top inner side of the support plate 205, so that the detection head 207 at the bottom of the support plate 205 is always in a vertical state, and the contact detection of the electrode column of the lithium battery can be stably performed. The bottom of the electromagnet 306 is fixedly installed with a top rod 307 The top rod 307 extends downward and the bottom end is flush with the middle height of the detection head 207 when it is retracted. The bottom of the installation groove 302 is fixedly connected to the base 308. The bottom of the inner cavity of the base 308 is fixedly installed with a reset spring 309. The top of the reset spring 309 is fixedly connected to the bottom of the pass electromagnet 306 to support the pass electromagnet 306. If a problem is found in the lithium battery during the detection, the pass electromagnet 306 will be powered off and demagnetized. The pass electromagnet 306 will automatically move up under the elastic support of the reset spring 309. At this time, the inner side of the top of the support plate 205 loses its elasticity. The inner side of the bottom of the detection head 207 is squeezed, so the detection head 207 moves outward and extends outward under the support of the support spring 209, and the top of the support plate 205 moves inward. At this time, the electromagnet 306 is energized again, and the magnetic strength of the electromagnet 306 is controlled by controlling the magnitude of the current in the electromagnet 306, so that the electromagnet 306 moves downward and the limit block 305 moves outward, so that the top plate 304 squeezes the inner side of the top of the support plate 205 outward, and the force is just enough to make the four detection heads 207 move outward. 07 is used to clamp the top of the lithium battery electrode column. After the clamping is completed, the lifting frame 201 is controlled to rise by the electric cylinder 105. After the lithium battery pack 103 is taken out from the inside of the card slot 101, the current inside the electromagnet 306 is increased at this time, so that the magnetism of the electromagnet 306 is enhanced, so that the electromagnet 306 moves downward quickly, and the top of the lithium battery is hit by the top rod 307 at the bottom of the electromagnet 306, so that the lithium battery is detached and falls into the inside of the operating platform 1 at the bottom, thereby removing the problematic lithium battery.

[0032] Example 3 further optimizes a lithium battery positioning detection device provided in Example 2. Specifically, Figure 2 and Figure 7As shown, the fixed ring 202 is a stator, and the rotating ring 203 is a rotor. The rotating ring 203 is rotatably installed inside the fixed ring 202. The fixed ring 202 is driven by an electromagnetic drive to rotate the rotating ring 203. The bottom of the detection head 207 is provided with frosting. Before detection, the bottom of the detection head 207 is first controlled to make slight contact with the top of the lithium battery electrode column. At this time, the rotating ring 203 is driven to rotate by the fixed ring 202, so that the frosted part at the bottom of the detection head 207 can grind the top of the electrode column and remove the slight burrs around the top of the electrode column, so that the detection head 207 can be better connected with the lithium battery. The arc position at the bottom of the detection head 207 is connected and conducted with the electrode column at the top of the lithium battery. The inner side of the detection head 207 is made of rubber material, which can clamp the electrode column of the lithium battery to prevent the lithium battery from slipping. The detection head 207 moves vertically downward to directly contact the electrode column at the top of the lithium battery, and the detection head 207 opens outward to clamp the electrode column of the lithium battery.

[0033] The use process of a lithium battery positioning detection system and device provided by the present invention is as follows: Put the lithium battery pack 103 into the slot 101 opened on the top of the operating platform 1, and then control the lifting frame 201 to descend through the electric cylinder 105, so that the frosted part at the bottom of the detection head 207 slightly contacts the arc at the top of the electrode column, and then drive the rotating ring 203 to rotate by electromagnetic action through the fixed 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 column; Then, the electric cylinder 105 controls the detection head 207 to further sink, so that the detection head 207 compresses the support spring 209 to closely contact the electrode column on the top of the lithium battery 104, and slightly opens outward under the action of pressure, so that the arc-shaped part inside the detection head 207 contacts the arc-shaped part of the lithium battery electrode column. At this time, the entire circumference of the electrode column is detected by the four detection heads 207 to prevent local poor contact. After the detection is completed, the electromagnet 306 on the top of the problematic lithium battery is powered off immediately. At this time, the electromagnet 306 will automatically move up under the elastic support of the reset spring 309, so that the inner side of the support plate 205 on the top of the detection head 207 loses support. At this time, the support plate 205 will move the hinge block 204 inward. The side is squeezed and the bottom of the detection head 207 is expanded outward, so that the inner rubber part of the detection head 207 wraps and clamps the side of the lithium battery electrode column. At this time, a slight current is input to the electromagnet 306 to move the electromagnet 306 downward, so that the top plate 304 moves outward, and the detection head 207 clamps the top of the electrode column. After the clamping is completed, the lifting frame 201 is controlled to move up by the electric cylinder 105, and then the lithium battery pack 103 is taken out from the inside of the card slot 101. At this time, the current of the electromagnet 306 is increased again. The electromagnet 306 will sink quickly under the action of strong magnetic attraction, and the top rod 307 will push the lithium battery to the bottom and fall into the bottom of the card slot 101 into the operating platform 1, thereby completing the removal of the problematic lithium battery.
