[0038] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0039] Existing battery assembly production lines do not have battery status detection devices and are unable to obtain the health status and performance characteristics of the batteries, such as batteries with abnormal voltage or low capacity, resulting in uneven quality of battery products leaving the factory.

[0040] In order to solve the above problems, a detection device and a removal mechanism are set up on the battery assembly production line to detect the battery products to be shipped out and remove the batteries that do not meet the quality standards.

[0041] As shown in the figure, the present application discloses a battery status detection system, including a first track 10, a second track 20, a lifting track 30 and a detection device 40. The second track 20 is arranged at the lower end of the first track 10; a first lifting mechanism is arranged at the lower end of the lifting track 30, and the first lifting mechanism drives the lifting track 30 to switch between the first position and the second position;

[0042] A detection device 40, which is disposed at the upper end of the first track 10, and a vertical projection of the detection device 40 falls directly above the lifting track 30;

[0043] Among them, when the lifting track 30 is in the first position, the lifting track 30 and the first track 10 are at the same height, forming a first transportation route; when the lifting track 30 is in the second position, the lifting track 30 and the second track 20 are at the same height, forming a second transportation route.

[0044] It can be understood that the first track 10 is used to carry and transport the battery 50 to be tested, ensuring that the battery 50 can move smoothly during the test. The second track 20 corresponds to the position of the first track 10, is arranged below the first track 10, and is used to receive the battery 50 that fails the test. The first track 10 is arranged on the first workbench, and the second track 20 is arranged on the second workbench.

[0045] The lifting track 30 can switch between the first track 10 and the second track 20, thereby forming a first transport route and a second transport route, wherein the first transport route is used to transport batteries 50 that have passed the inspection, and the second transport route is used to transport batteries 50 that have failed the inspection. The detection device 40 is installed above the first track 10, and is used to detect various performance indicators of the battery 50. The performance indicators include voltage, current, and temperature during use.

[0046] Among them, the first track 10, the second track 20 and the lifting track 30 can be chain conveyor belts, which are composed of metal or plastic chain links, and the chain links are driven by rollers or gears to transport the batteries 50. It can also be a belt conveyor, which is composed of a rubber or PVC belt, and the motor drives the roller or roller to drive the belt to move to transport the batteries 50. The above two modes of transmission and transportation can be driven by a servo motor, and the motor speed can be adjusted by a frequency converter, so that the conveying speed can be dynamically adjusted according to the production rhythm. The above processes are all automated through PLC control.

[0047] In addition, a plurality of positioning grooves are provided on the first track 10, and the positioning grooves are used to limit the position of the battery 50 to be tested. Since the conveyor belt on the first track 10 has to start and stop many times, the battery 50 is easily affected by the inertia of movement and deviates from the first track 10. Therefore, a plurality of positioning grooves are provided to limit the position of the battery 50. A sensor can be provided in each positioning groove to detect whether the battery 50 is correctly placed and ensure that the battery 50 is in a stable position during the detection process.

[0048] The size and shape of the positioning groove are customized according to the specifications of the battery 50 to be tested, so as to adapt to batteries 50 of different models.

[0049] The first lifting mechanism at the lower end of the lifting rail 30 may be composed of a motor, a lead screw, and a nut. The motor drives the lead screw to rotate, and the nut on the lead screw moves up and down, driving the lifting rail 30 to rise or fall. The first lifting mechanism may also be a cylinder driving mechanism, which drives the cylinder to extend and retract through compressed air, thereby driving the lifting rail 30 to rise or fall. The first lifting mechanism may also be a hydraulic driving mechanism, which realizes the lifting action through a hydraulic pump and an oil cylinder, and the oil cylinder drives the lifting rail 30 to rise or fall.

[0050] In the initial state, the lifting track 30 is at the first position, forming a first transport route with the first track 10. The first track 10 is used to carry the battery 50 to be tested, and is driven by a servo motor to achieve precise positioning, ensuring that the battery 50 can accurately reach the testing position before testing. After the battery 50 to be tested is transported to the lifting track 30 via the first track 10, the testing device 40 performs a status test on the battery 50;

[0051] When the detection result shows that the battery 50 does not meet the factory standards, the first lifting mechanism is started, driving the lifting rail to descend to the second position, and the lifting rail and the second rail form a second transportation route. The batteries 50 that do not meet the standards are transported to the waste area for centralized collection via the second transportation route.

[0052] The detection device 40 is installed above the first track 10, with its vertical projection falling directly above the lifting track 30, ensuring that the battery 50 placed on the lifting track 30 can be accurately positioned with the detection device 40, so that the detection end of the detection device 40 corresponds to the electrode of the battery 50.

[0053] The battery status detection system disclosed in the present application is provided with a detection device 40, a first track 10, a second track 20 and a lifting track 30 on the battery assembly production line. The battery 50 is transported to the lifting track 30 via the first track 10. After the battery 50 is detected by the detection device 40, if the status of the battery 50 meets the factory requirements, the lifting track 30 will transfer the battery 50 to the first track 10 at the rear for transportation to the packaging section. If the status of the battery 50 does not meet the factory requirements, the lifting track 30 will descend to the height of the second track 20 and transfer it to the second track 20, and the second track 20 will recycle the battery. In this way, the assembled battery 50 to be shipped is detected, and the problematic battery 50 is removed from the assembly line.

[0054] In some embodiments, the detection device 40 includes: a second lifting mechanism and a housing; the housing is connected to the driving end of the second lifting structure, and a voltage sensor, a current sensor and a processor are arranged inside the housing;

[0055] A temperature sensor, the temperature sensor is arranged at one end of the housing away from the second lifting mechanism;

[0056] A detection probe extending out of the housing and used to contact an electrode of the battery 50;

[0057] Among them, the voltage sensor, the current sensor, and the temperature sensor are all electrically connected to the processor, and the detection probe is electrically connected to the voltage sensor, the current sensor, and the temperature sensor respectively.

[0058] It can be understood that the detection device 40 is located above the first track 10 and is fixed by an installation bracket. The installation bracket wraps the support column and the crossbeam. The support columns are respectively arranged on both sides of the first track 10. The two ends of the crossbeam are respectively fixed to the support columns and have a certain distance from the first track 10. A second lifting mechanism is installed on the crossbeam. The second lifting mechanism can be a cylinder driving mechanism. The cylinder is driven to extend and retract by compressed air, thereby driving the shell to rise or fall, so that the shell is close to or away from the battery 50 on the first transport route, and the detection probe is used to contact the electrode of the battery 50, so as to detect the status of the battery 50.

[0059] The lead screw can also be driven by a servo motor, and the nut on the lead screw moves up and down, driving the housing to rise or fall.

[0060] Wherein, in the case where the second lifting mechanism is a cylinder drive mechanism, the telescopic rod is fixedly connected to the shell and stably performs the telescopic action so that the detection probe on the shell can accurately contact the electrode of the battery 50. The shell is used to accommodate and protect the outer shell of the internal components of the detection device 40. The voltage sensor: is used to measure the voltage across the battery 50. The current sensor is used to measure the current during the charging and discharging process of the battery 50. The temperature sensor is used to monitor the temperature of the battery 50, and is usually arranged on a side of the shell away from the second lifting mechanism and close to the battery 50. The detection probe is used to contact the electrode of the battery 50 to achieve the measurement of voltage, current and temperature. The detection probe can be a spring probe, a fixed probe or an electric probe.

[0061] Battery detection working process:

[0062] Initial state: The detection device 40 is raised to the highest position by the second lifting mechanism, and the detection probe is away from the electrode of the battery 50. At this time, the battery 50 is placed in the positioning groove of the first track 10 to ensure that the battery 50 is in the correct position. The first track 10 transports the battery 50 to the lifting track 30, and at this time, the detection device 40 is located directly above the battery 50.

[0063] The positioning method may be to use a photoelectric sensor to detect the position of the battery 50 by emitting a light beam and receiving the reflected light beam when the battery 50 passes by. The emitter and receiver of the photoelectric sensor are respectively arranged on the support column relative to each other. When the battery 50 passes by, the light beam is blocked, and the receiver detects the signal interruption, thereby determining the position of the battery 50. A signal is sent to the processor, and the detection work is started after receiving the signal.

[0064] The detection probe descends: the second lifting mechanism drives the housing to descend, so that the detection probe gradually approaches the electrode of the battery 50. The contact sensor at the front end of the probe detects the contact with the electrode and feeds back the signal to the processor.

[0065] Data collection: After the contact sensor confirms that the probe is in contact with the electrode, the voltage sensor, current sensor, and temperature sensor start working. The voltage sensor measures the voltage across the battery 50. The current sensor measures the current during the charge and discharge process of the battery 50. The temperature sensor monitors the temperature of the battery 50, wherein the temperature sensor is an infrared temperature sensor that receives infrared radiation emitted by the battery 50 and converts the infrared radiation into an electrical signal. The circuit inside the sensor converts the electrical signal into a temperature value. Since the infrared temperature sensor does not need to be in direct contact with the battery 50, interference with the battery 50 can be avoided.

[0066] Data processing and storage: All data collected by the sensors are transmitted to the processor via signal lines. The processor processes the data, identifies the health status of the battery 50, and stores the results in the internal memory.

[0067] Track switching: After the detection is completed, the detection status of the battery 50 is identified. When the health status of the detected battery 50 does not meet the factory standards, the first lifting mechanism drives the lifting track 30 to switch from the first position to the second position, so that the battery 50 is transferred from the first track 10 to the second track 20, and transported to its recovery area via the second track 20.

[0068] When the health status of the detected battery 50 meets the factory standard, the lifting track 30 transfers the battery 50 to the first track 10 at the rear, and the first track 10 transfers the battery 50 to the packaging section for packaging and shipment.

[0069] Therefore, a detection device 40 and a lifting track 30 are set on the battery 50 assembly production line to cooperate with the second track 20. After the battery 50 products to be shipped are tested, the batteries 50 that are in poor health and do not meet the quality standards can be removed from the first track 10 through the lifting track 30 and collected using the second track 20.

[0070] In some embodiments, the detection device 40 further includes a control panel, which is provided with a touch screen.

[0071] It is understandable that the processor transmits the detection results to a remote server or control center via the wireless communication module. The control panel displays the detection results, and the user can view detailed information through the touch display.

[0072] In some embodiments, the detection probe is a spring probe.

[0073] It can be understood that the spring probe is elastic and can adapt to the different heights of the battery 50 electrodes and avoid wear on the battery 50 electrodes. The spring probe can provide stable contact pressure and automatically adjust to adapt to slight position changes of the battery 50 electrodes, ensuring good contact and detection accuracy.

[0074] In some embodiments, a contact sensor is disposed at the front end of the spring probe.

[0075] It is understandable that in order to ensure the accuracy and safety of the detection during the battery 50 detection process, a contact sensor is provided at the end of the spring probe, and when the spring probe contacts the electrode of the battery 50, the contact state can be automatically identified and fed back to the processor to ensure the accuracy of the detection. When the probe contacts the electrode, the contact is closed and a signal is sent to the processor.

[0076] Among them, the contact sensor can detect whether the detection probe has established a good electrical connection with the electrode of the battery 50. Only after confirming that the probe is in good contact with the electrode will the detection process be started to avoid false detection or inaccurate data caused by poor contact. The contact sensor can prevent the detection from being started when the probe is not fully in contact with the electrode, and avoid arcs, sparks and other phenomena caused by excessive current or poor contact, thereby protecting the detection equipment and the battery 50 from damage.

[0077] In some embodiments, the detection device 40 further includes a wireless communication module, which is electrically connected to the processor and is used to transmit the detection data to a remote server or a control center.

[0078] It is understandable that by adding a wireless communication module to the battery status detection system, the detection data can be remotely transmitted to a server or control center, thereby realizing centralized management and real-time monitoring. The wireless communication module transmits the battery 50 status data collected by the detection device 40 to the remote server or control center via a wireless network. Through the wireless communication module, managers can monitor the status of the battery 50 in real time on the remote server or control center, and promptly discover and deal with possible problems. When an abnormal battery 50 status is detected, the wireless communication module can immediately send an alarm message to the control center to facilitate timely action.

[0079] Among them, a Wi-Fi module can be used as a wireless communication module. The Wi-Fi module is electrically connected to the processor of the detection device 40 to receive data sent by the processor. The Wi-Fi module is connected to an external wireless network through an antenna.

[0080] In some embodiments, the control panel further includes an alarm module.

[0081] It is understandable that when an abnormal state of the battery 50 is detected, the alarm module can emit an audible and visual alarm to alert the operator.

[0082] In some embodiments, the first rail 10 is provided with a plurality of positioning grooves.

[0083] It is understandable that in order to ensure that the battery 50 can be accurately positioned and fixed during the detection process, it is necessary to prevent the spring probe from being unstable or unable to contact the battery 50 electrode due to position deviation during the detection process.

[0084] Among them, a plurality of positioning grooves are arranged at intervals on the first track 10, and the positioning grooves are rectangular grooves with a certain depth, and arc-shaped spring sheets are arranged on the inner walls of the grooves, respectively. The spring sheets protrude toward the middle part of the grooves, thereby compressing the internal space of the grooves. When the battery 50 is placed in the grooves, the spring sheets are squeezed by external force, deformed and generate elastic force, thereby firmly limiting the battery 50 in the middle position of the grooves.

[0085] In some embodiments, the first lifting mechanism and the second lifting mechanism are cylinder drive mechanisms.

[0086] The cylinder drive mechanism can be understood to complete the lifting action in a short time through the rapid inflation and deflation of compressed air, which is suitable for application scenarios that require rapid response. This rapid response feature helps to improve production efficiency and shorten the inspection cycle.

[0087] In addition, compared with electric or hydraulic drive mechanisms, cylinder drive mechanisms are low-cost, simpler in structure, and easier to install and maintain. There is no complicated electrical wiring or hydraulic piping, which reduces the difficulty of installation and maintenance.

[0088] In some embodiments, the present disclosure provides a method for detecting a state of a battery 50, comprising the following steps:

[0089] Place the battery 50 to be tested in the positioning groove of the first track 10;

[0090] The sensor in the positioning slot detects whether the battery 50 is correctly placed, and transmits the detection result to the processor; wherein a proximity sensor or a photoelectric sensor is installed in each positioning slot to detect whether the battery 50 is correctly placed.

[0091] The detection device 40 is lowered to a predetermined position by the second lifting mechanism, so that the detection probe contacts the electrode of the battery 50;

[0092] The voltage, current and temperature data of the battery 50 are collected in real time through the voltage sensor, the current sensor and the temperature sensor;

[0093] Analyze the status of the battery 50 according to the collected data, and determine whether the battery 50 is qualified according to the set standards;

[0094] If qualified, the lifting track 30 transfers the battery 50 to the first track 10 at the rear, and the first track 10 transfers the battery 50 to the packaging section for packaging and shipment.

[0095] If unqualified, the first lifting mechanism drives the lifting track 30 to switch from the first position to the second position, so that the battery 50 is transferred from the first track 10 to the second track 20 and transported to the recovery area via the second track 20 .

[0096] The detection results are stored in the data storage module and transmitted to the remote server or control center through the wireless communication module.

[0097] It should be noted that the first track 10, the second track 20 and the lifting track 30 are all multiple and arranged in parallel; there are multiple detection devices 40, and the detection devices 40 are arranged one by one with the lifting tracks 30. It is possible to detect multiple batteries 50 at the same time. Improve work efficiency. So far, the various embodiments disclosed in the present application have been described in detail.
