Description

Technical Field

[0001] This invention belongs to the field of lithium battery testing technology, specifically relating to a battery testing device and method that utilizes magnetically levitated X-rays. Background Technology

[0002] With the continuous growth in demand for lithium batteries, end-user applications are placing increasingly higher demands on battery quality. To ensure consumer safety, major lithium battery manufacturers are increasing their investment in battery safety testing technologies, thus promoting the development of lithium battery testing technology. Online X-ray inspection devices, due to their strong penetrating power and excellent detection results, have become a common testing system.

[0003] Existing online X-ray inspection devices for lithium batteries often use belt conveyors or mechanical handling to transport batteries to the inspection position. Both of these methods are not only inefficient but also have low positioning accuracy, thus requiring a secondary precision positioning mechanism. After the battery is transported to the inspection station, the precision positioning mechanism is used to perform motion positioning to ensure the clarity of the obtained inspection images and thus ensure the accuracy of the battery inspection and evaluation results.

[0004] Therefore, it is necessary to optimize existing online X-ray inspection devices to address their problems of low delivery efficiency and low positioning accuracy. Summary of the Invention

[0005] The purpose of this invention is to provide a battery inspection device that utilizes magnetically levitated X-rays, aiming to solve the problems of low delivery efficiency and low positioning accuracy of existing online X-ray inspection devices.

[0007] A magnetic levitation transport module includes a guide rail and a battery cell fixture, wherein the battery cell fixture is slidably connected to the guide rail via magnetic levitation, and the battery cell fixture is used to transport batteries;

[0008] An X-ray inspection module is installed on one side of the guide rail and is used to inspect the batteries on the battery cell fixture.

[0009] Another objective of this invention is to provide a battery detection method using magnetically levitated X-rays, the method comprising:

[0010] The battery to be tested is transferred from the material line to the cell fixture;

[0011] The battery is transported to the test station by a magnetically levitated cell fixture, and the battery is tested using an X-ray detection module.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0025] In the description of this invention, it should be noted that if terms such as "upper," "lower," "inner," or "back" appear, indicating orientation or positional relationship, they are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0026] Furthermore, in the description of this invention, unless otherwise explicitly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention in light of the specific circumstances.

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] In one embodiment, such as Figure 1 As shown, a battery detection device utilizing magnetic levitation X-rays includes:

[0029] The magnetic levitation conveying module 2 includes a guide rail 201 and a battery cell fixture 202. The battery cell fixture 202 is slidably connected to the guide rail 201 by magnetic levitation, and the battery cell fixture 202 is used to convey batteries.

[0030] An X-ray inspection module is installed on one side of the guide rail 201 and is used to inspect the batteries on the battery cell fixture 202.

[0031] In this embodiment, the guide rail 201 is slidably connected to the cell fixture 202 via magnetic levitation. There is no physical contact or friction between them, allowing the cell fixture 202 to move at high speed. Currently, the industry mainly uses logistics lines or mechanical handling, which are inefficient. The average time for a single battery to travel 0.5m is 0.8 seconds, while using a magnetic levitation guide rail, the travel time for a single battery is only 0.384 seconds. Therefore, the magnetic levitation transport module 2 used in this embodiment is significantly more efficient than existing handling methods. Since the position of the X-ray inspection module's inspection station is known, the guide rail 201 can determine the driving scheme for each cell fixture 202 based on the current positions of all cell fixtures, ensuring that each cell fixture accurately reaches the inspection station, thus guaranteeing transport accuracy. The X-ray inspection module, located on one side of the guide rail 201, can inspect each battery moving from the inspection station without requiring movement, thus ensuring inspection efficiency.

[0032] Preferably, the X-ray inspection module further includes an identification unit and a data transmission unit. The identification unit is used to obtain the unique serial number of the battery under test, and the data transmission unit is used to upload the inspection results. The X-ray inspection module can obtain the unique serial number of the battery currently being inspected through the identification unit, thereby determining the information of the battery and thus matching the inspection results with the batteries one by one. After the inspection is completed, the X-ray inspection module can upload the serial number of the battery currently being inspected and the inspection results through the data transmission unit, which facilitates the processing of the battery based on the inspection results in subsequent steps.

[0033] In one embodiment, such as Figure 1 and Figure 2 As shown, the guide rail 201 is annular, and a plurality of loading and unloading modules 1 are provided on one side. The loading and unloading module 1 includes:

[0034] Pillar 101;

[0035] The crossbeam 102 is fixedly connected to the support column 101;

[0036] The first moving component 103 is disposed on the crossbeam 102 and is used to drive the clamping component to move closer to or away from the guide rail;

[0037] The first lifting component 104 is connected to the first moving component 103 and is used to drive the clamping component 105 to lift.

[0038] The clamping assembly 105 is connected to the first lifting assembly 104 and is used to transport the battery on the magnetic levitation conveying module or logistics line.

[0039] The guide rail 201 is circular, changing the traditional linear battery transport method to a circular rotary battery transport method, which makes the spatial layout of the equipment more flexible and greatly improves the space utilization. The driving mechanism of the first moving component 103, the first lifting component 104, and the clamping component 105 can be implemented by a lead screw, slider mechanism, gear, rack and pinion mechanism, hydraulic cylinder mechanism, or pneumatic cylinder mechanism. This embodiment does not limit its specific structure. Through the first moving component 103, the first lifting component 104, and the clamping component 105, the battery can perform reciprocating motion and lifting motion, thereby transporting the battery from the logistics line to the cell fixture 202 or from the cell fixture 202 to the logistics line. Preferably, there are 4 loading and unloading modules 1, and each loading and unloading module 1 has 2 pairs of clamps 106, so that the loading and unloading module can transport 4 batteries to be tested from the logistics line to the cell fixture 202 and simultaneously transport 4 tested batteries from the cell fixture 202 to the logistics line, thereby ensuring sufficient loading and unloading.

[0040] In one embodiment, such as Figure 1 As shown, the battery cell fixture includes a magnetic drive actuator 203 and a placement plate 204. The magnetic drive actuator 203 is slidably connected to the guide rail 201 by magnetic levitation. The magnetic drive actuator 203 is disposed on one side of the placement plate 204, and the placement plate 204 is provided with a placement groove 205.

[0041] This embodiment illustrates the operation of the magnetic levitation rail, as shown in Table 1 below:

[0042] Table 1: Operation Status of Magnetic Levitation Rail

[0043]

[0044] As shown in the table above, the cell fixture 202 achieves high-precision repeatability and operates without vibration, whether moving in a straight line or navigating rounded corners. In current industry-standard logistics lines or mechanical handling, a single battery takes an average of 0.5m to travel in 0.8s, while the magnetically levitated cell fixture only takes 0.384s, making it twice as efficient as existing technologies. Furthermore, even when navigating rounded corners, the cell fixture maintains an average speed of 1m / s, significantly better than the 0.625m / s average speed achieved by current industry-standard handling methods in straight-line motion. Therefore, magnetic levitation transport offers excellent transport efficiency and precision, with smooth and vibration-free operation.

[0045] The magnetic drive actuator 203 is connected to the guide rail 201 via magnetic levitation sliding connection. Utilizing the high precision and speed of the magnetic linear motion module, it enables rapid and accurate stopping at the inspection station without vibration. This allows the imaging system to obtain clear images without waiting for secondary precision positioning of the battery, ensuring the accuracy of subsequent inspection and judgment, thereby improving inspection precision and efficiency. Multiple magnetic drive actuators 203 can be arranged on the guide rail 201, each capable of independent movement, offering high flexibility and eliminating the need for synchronous waiting as in traditional transportation methods, thus improving transport efficiency. Furthermore, the magnetic drive actuators 203 can be quickly installed or removed from the guide rail 201, facilitating equipment maintenance and product changeover. The placement slot 205 corresponds to the battery model, ensuring that the battery, even when quickly passing through curves, will not shift, thus guaranteeing stable placement on the placement plate 204.

[0046] In one embodiment, such as Figure 1 and Figure 3 As shown, the X-ray detection module includes an angle detection unit, which comprises four angle detection sub-units, each of which includes:

[0047] First base 301;

[0048] The second moving component 302 is disposed on the first base 301 and is used to drive the first column 303 to move closer to or away from the guide rail 201;

[0049] The first column 303 is mounted on the second movable component 302;

[0050] The second lifting component 304 is disposed on one side of the first column 303 and is used to drive the first imaging component 306 to lift.

[0051] The third lifting component 305 is disposed on one side of the first column 303 and is used to drive the first detection component 307 to lift.

[0052] The first imaging component 306 is disposed on the second lifting component 304 and is used to receive X-rays emitted by the first detection component 307;

[0053] The first detection component 307 is disposed on the third lifting component 305 and is used to emit X-rays so that the X-rays pass through the test angle of the battery.

[0054] The second moving component 302, the second lifting component 304, and the third lifting component 305 can be implemented using a lead screw, slider mechanism, gear, rack and pinion mechanism, hydraulic cylinder mechanism, or pneumatic cylinder mechanism; this embodiment does not limit their specific structure. Through the second moving component 302, the second lifting component 304, and the third lifting component 305, the first imaging component 306 and the first detection component 307 can be adjusted according to the different battery models and sizes to be detected, thereby allowing X-rays to pass through the tested corner of the battery to obtain the coverage of the positive and negative electrode sheets at one corner, thus improving the versatility of the corner detection subunit. By setting four corner detection subunits, each subunit only detects one corner of the battery under test, eliminating the need to rotate the battery or move the corner detection subunit at the detection station, thus improving detection efficiency.

[0055] In one embodiment, such as Figure 1 and Figure 4 As shown, the X-ray detection module further includes a large-area detection unit, which comprises several large-area detection sub-units, each including:

[0056] Second base 501;

[0057] The third moving component 502 is disposed on the second base 501 and is used to drive the second column 503 to move closer to or away from the guide rail 201;

[0058] The second column 503 is disposed on the third moving component 502;

[0059] The fourth lifting component 504 is disposed on one side of the second column 503 and is used to drive the second imaging component 506 to lift.

[0060] The fifth lifting component 505 is located on one side of the second column 503 and is used to drive the second detection component 507 to lift.

[0061] The second imaging component 506 is disposed on the fourth lifting component 504 and is used to receive X-rays emitted by the second detection component 507;

[0062] The second detection component 507 is disposed on the fifth lifting component 505 and is used to emit X-rays so that the X-rays pass through the test surface of the battery.

[0063] The third moving component 502, the fourth lifting component 504, and the fifth lifting component 505 can be implemented using a lead screw, slider mechanism, gear, rack and pinion mechanism, hydraulic cylinder mechanism, or pneumatic cylinder mechanism; this embodiment does not limit their specific structure. Through the third moving component 502, the fourth lifting component 504, and the fifth lifting component 505, the second imaging component 506 and the second detection component 507 can be adjusted according to the different battery models and sizes to be detected, thereby allowing X-rays to penetrate the surface of the battery to be tested, thus detecting whether there are foreign objects, electrode powder shedding, electrode wrinkles, or other problems, thereby ensuring the versatility of the large-area detection subunit.

[0064] Preferred, such as Figure 1 As shown, there are two large surface detection units. Between the corner detection unit 3 and the large surface detection unit 5, there is also a buffer station 4. The battery that has completed the corner detection will wait here for the large surface detection unit to be ready. Then, it and the next battery that has completed the corner detection will go to the detection station of the two large surface detection sub-units respectively to be detected at the same time, thereby improving the detection efficiency.

[0065] In one embodiment, the guide rail 201 is equipped with several fans, which are located on the guide rail 201 on one side of the X-ray detection module's detection station and / or on one side of the loading / unloading module's loading / unloading station. The magnetic drive actuator 203 generates high temperatures due to its high-speed movement. It stops moving during detection and loading / unloading operations, waiting for the detection or loading / unloading to complete. Therefore, placing fans at these two locations helps cool the magnetic drive actuator 203, extending its service life and enabling it to operate for extended periods.

[0066] In one embodiment, this application also provides a battery detection method using magnetically levitated X-rays, which is applied to the battery detection device using magnetically levitated X-rays in the above embodiment, and includes steps S102-S106:

[0067] Step S102: Transfer the battery to be tested from the material line to the cell fixture;

[0068] Step S104: The battery is transferred to the test station by a magnetic levitation drive cell fixture, and the battery is tested by an X-ray detection module.

[0069] Step S106: Transfer the tested battery from the cell fixture to the material line.

[0070] In this process, the loading / unloading module 1 transports the battery under test from the logistics line to the placement slot 205 of the cell fixture 202. The guide rail 201 uses magnetic levitation to drive the cell fixture 202 to transport the battery to the testing station. The X-ray detection module inspects the battery and uploads the results. After inspection, the loading / unloading module 1 transports the inspected battery from the cell fixture 202 back to the logistics line.

[0071] In one embodiment, step S202 is included before step S102:

[0072] In step S202, the detection areas of the four corner detection subunits and the large-area detection subunit are adjusted according to the battery model, and the cell fixture corresponding to the battery model is installed on the magnetic levitation conveying module.

[0073] Since both the corner detection unit and the large-area detection unit are equipped with moving and lifting components, the detection area can be adjusted according to the battery model. Therefore, before using the device, the detection areas of the four corner detection subunits and the large-area detection subunit need to be adjusted according to the model of the battery to be tested. This allows the four corner detection subunits to detect the four corners of the battery to be tested, and each large-area detection unit to detect the surface of the battery to be tested. This enables both the corner detection subunits and the large-area detection subunits to detect different battery models. Because the placement slot 205 on the cell fixture 202 changes depending on the battery model, the cell fixture 202 and the guide rail 201 are magnetically levitated and slidably connected during use, and are engaged with the guide rail 201 via the magnetic drive actuator 203 when not in use. Therefore, the corresponding cell fixture 202 can be quickly installed on the guide rail according to the model of the battery to be tested.

[0074] In one embodiment, step S104 specifically includes steps S302 to S306:

[0075] Step S302: The batteries are sent to each corner detection station in sequence, and the four corners of the batteries are detected by the corner detection unit.

[0076] Step S304: Transfer the battery from the corner detection station to the buffer station;

[0077] Step S306: Transfer the battery from the buffer station to any large-area inspection station and use the large-area inspection unit to inspect the battery surface.

[0078] Since each corner detection subunit only detects one corner of the battery under test, the cell fixture 202 needs to transport the battery under test through each corner detection station sequentially, and then the corner detection unit performs the detection and uploads the results. Because there are two large-area detection subunits, and the large-area detection speed is relatively slow, a buffer station 4 is provided. This buffer station 4 can accommodate one cell fixture 202, allowing batteries that have completed corner detection to wait in the buffer station. The next battery to complete corner detection, along with the battery waiting in the buffer station, will be transported by the cell fixture 202 to the detection stations of the two large-area detection subunits for simultaneous detection. After the large-area detection unit completes its detection, it will upload the results.

[0079] The battery detection method using magnetic levitation X-rays of this application will be described in full below, in sequence:

[0080] Before testing, the detection areas of the four corner detection subunits and the large surface detection subunit are adjusted according to the model of the battery to be tested. This ensures that the four corner detection subunits will detect the four corners of the battery to be tested, and each large surface detection unit will detect the surface of the battery to be tested. The corresponding cell fixture 202 is then installed on the guide rail 201.

[0081] During testing, since there are four loading / unloading modules 1, two for loading and two for unloading, and each module 1 has two pairs of clamps 206, each loading / unloading module 1 can transport four batteries to be tested from the logistics line to the placement slots 205 of the four cell fixtures 202. The cell fixtures 202 then transport the batteries sequentially through the four corner detection subunits. After completing the detection, the corner detection subunits upload the unique serial number of the battery and the corresponding test result. Batteries that have completed corner detection wait at buffer station 4. The next battery to complete corner detection, along with the batteries waiting at the buffer station, will be transported by the cell fixtures 202 to the detection stations of the two large-area detection subunits for simultaneous testing. After completing the large-area detection, the large-area detection subunits also upload the unique serial number of the battery and the corresponding test result. After the battery completes all tests, the cell fixture 202 will transport it to the loading and unloading module. The two unloading modules will move the four tested batteries from the cell fixture 202 to the logistics line at one time.

[0082] Utilizing a magnetic levitation conveyor module, compared to the 0.8-second time required by traditional logistics lines, the magnetic levitation high-speed circular motion track transports the fixture and battery to a single inspection station in just 0.384 seconds, improving transportation efficiency by 100%. Furthermore, the battery can precisely stop at the inspection station, thus avoiding the impact of inaccurate track bearing on the inspection results. This also improves the efficiency and stability of the lithium battery X-ray inspection system. By setting up four corner inspection sub-units, each inspecting one corner of the battery, the efficiency of corner inspection is guaranteed. A buffer station is provided between the corner inspection units and the large-area inspection unit, with two large-area inspection sub-units. This allows the slower large-area inspection units to work simultaneously, preventing corner inspection units from stopping to wait for the large-area inspection units to become ready, thus ensuring overall inspection efficiency. Two separate loading and unloading modules ensure sufficient material intake and output.
