Description

[0002] The heating conditions of a lithium battery vacuum drying system include contact heating and air-assisted heating, using heating plates and heat pipes as heat sources, respectively. The system's heating rate and temperature uniformity are crucial evaluation indicators for lithium battery vacuum drying equipment. Temperature uniformity and heating rate are generally related to factors such as the baking process, battery materials and structure, cavity dimensions, and heating method. Improving heating rate and temperature uniformity requires the use of multiple in-furnace temperature sensors for lithium battery temperature testing, data acquisition, and analysis. Currently, the commonly used furnace temperature testing method is manual wiring. Since a single furnace consists of multiple cavities, multiple cavity positions within the furnace need to be tested to ensure temperature consistency in the lithium battery vacuum drying system. This enables initial temperature verification under full-load conditions during the early stages of production and rapid temperature verification during battery type changeover. Manual wiring for individual temperature testing of multiple cavity positions is difficult and involves a significant amount of repetitive work for operators. Summary of the Invention

The wireless transmitter is connected to an external device, which is equipped with a wireless receiver. The wireless transmitter and the wireless receiver cooperate to conduct a data transmission circuit for transmitting the temperature information of the test batteries. The power supply structure is connected to the tray and electrically connected to the thermometer.

[0005] Optionally, the tray includes a frame and a plurality of connecting rods extending along a first direction. The plurality of connecting rods are all connected to the frame and spaced apart along a second direction. The first direction and the second direction are perpendicular to each other. The receiving cavity is formed between any two adjacent connecting rods. Abutment portions are formed on both sides of the connecting rods. The abutment portions extend along the direction close to the receiving cavity and are used to support the test battery.

[0006] Optionally, each of the connecting rods is provided with a plurality of partition blocks, the plurality of partition blocks are spaced apart along the first direction and can slide relative to the connecting rod along the first direction, the partition blocks are formed with stop notches, and the stop notches of two adjacent partition blocks cooperate to clamp the test battery.

[0007] Optionally, the frame is detachably connected to an insulation board.

[0008] Optionally, the connection structure further includes a heat insulation cover, which is placed over the thermometer and connected to the tray.

[0009] In addition, the present invention also provides a temperature measurement method based on the furnace temperature measuring device described above, the temperature measurement method comprising:

[0015] Optionally, the steps for measuring temperature and obtaining temperature data and test reports according to preset conditions include:

[0016] The heating time and temperature are preset according to the type of battery being tested and the baking process.

[0017] After the preset heating time is achieved, the actual temperature of multiple temperature probes inside multiple test batteries is obtained;

[0018] Calculate the difference between the actual temperature of each temperature probe and the preset temperature based on the actual temperature of multiple temperature probes;

[0019] A non-conforming report is generated when the difference between the actual temperature and the preset temperature is greater than the preset tolerance range; a conforming report is generated when the difference between the actual temperature and the preset temperature is less than or equal to the preset tolerance range.

[0020] Optionally, the multiple test batteries are arranged in an array, and the step of obtaining temperature information of the multiple test batteries includes:

[0042] The present invention provides a furnace temperature measuring device 100.

[0043] In one embodiment, such as Figures 1 to 4 As shown, the furnace temperature measuring device 100 is used to test the temperature of a single furnace. The single furnace includes multiple cavity workstations. The furnace temperature measuring device 100 includes a tray 20, a connecting structure, a power supply structure 40, and multiple test batteries 10. Each test battery 10 is equipped with multiple temperature probes. The tray 20 forms multiple receiving cavities 25 for placing the test batteries 10. The connecting structure includes a thermometer 30, which is connected to the tray 20. The thermometer 30 includes a wireless receiver and a temperature measuring channel connected to the temperature probes. The wireless transmitter is connected to an external device, which is equipped with a wireless receiver. The wireless receiver and the wireless transmitter cooperate to conduct a data transmission circuit, which is used to transmit the temperature information of the test batteries 10. The power supply structure 40 is connected to the tray 20 and electrically connected to the thermometer 30.

[0044] Each test battery 10 is equipped with multiple temperature probes to measure the temperature at multiple locations within the test battery 10. The tray 20 has multiple receiving cavities 25, where the test batteries 10 are placed for installation. These cavities also accommodate conventional batteries undergoing normal vacuum drying. A thermometer 30 is installed and secured by connecting to the tray 20. The thermometer 30 includes a wireless transmitter and a temperature measurement channel connected to the temperature probes. The temperature probes transmit the measured temperature information to the wireless transmitter via the temperature measurement channel. The wireless transmitter connects to an external device equipped with a wireless receiver. The wireless receiver and transmitter work together to establish a data transmission circuit. This circuit transmits the temperature information of the test batteries 10. The external device processes the temperature information to perform furnace temperature testing on the cavity positions within the individual cell furnace. This ensures the consistency of the baking temperature in the lithium battery vacuum drying system, enabling initial temperature verification under full-load conditions during the early stages of production of the vacuum drying equipment, and rapid temperature verification during battery replacement processes. The power supply structure 40 is installed and fixed by connecting to the tray 20. The power supply structure 40 is electrically connected to the thermometer 30 and is used to supply power to the thermometer 30.

[0045] The furnace temperature measuring device 100 in this invention sets a temperature probe inside the test battery 10 and a wireless transmitter inside the temperature measuring instrument 30. The wireless transmitter and the wireless receiver of the external device cooperate to conduct data transmission circuits, thereby enabling furnace temperature testing of the cavity workstations inside the single furnace. This ensures the consistency of the baking temperature of the lithium battery vacuum drying system, realizes the initial temperature verification under full load conditions in the early stage of vacuum drying equipment production, and enables rapid temperature verification during battery replacement. It avoids the problems of difficult installation and wiring and easy wire tangling caused by wired data transmission, and reduces the repetitive workload of operators.

[0046] Specifically, the temperature measuring instrument 30 in this embodiment can refer to the furnace temperature tester of RSM.

[0047] In one embodiment, please refer to the reference Figure 1 and Figure 2 The tray 20 includes a frame 21 and a plurality of connecting rods 22 extending along a first direction. The plurality of connecting rods 22 are all connected to the frame 21 and are spaced apart along a second direction. The first direction and the second direction are perpendicular to each other. A receiving cavity 25 is formed between any two adjacent connecting rods 22. Abutting portions 221 are formed on both sides of the connecting rods 22. The abutting portions 221 extend along the direction close to the receiving cavity 25 and are used to support the test battery 10.

[0048] The first direction is Figure 1 The left and right directions, the second direction is Figure 1 The front and back directions in the middle.

[0049] The connecting rod 22 extends in the left-right direction, and multiple connecting rods 22 are spaced apart in the front-back direction. The connecting rods 22 are installed and fixed by connecting to the frame 21. A receiving cavity 25 is formed between any two adjacent connecting rods 22 for placing the test battery 10. Abutment portions 221 are formed on the front and rear sides of the connecting rod 22. The abutment portions 221 extend in the direction close to the receiving cavity 25. By setting the abutment portions 221, the test battery 10 is supported, and the contact area between the test battery 10 and the heating plate is increased, thereby improving the vacuum drying efficiency of the test battery 10.

[0050] In one embodiment, please refer to the reference Figure 1 and Figure 2 Each connecting rod 22 is provided with multiple partition blocks 23. The multiple partition blocks 23 are spaced apart along the first direction and can slide relative to the connecting rod 22 along the first direction. Each partition block 23 has a stop notch 231. The stop notches 231 of two adjacent partition blocks 23 cooperate to clamp the test battery 10.

[0051] Multiple partition blocks 23 are provided on the connecting rod 22, spaced apart in the left-right direction. Each partition block 23 has a stop notch 231. The stop notches 231 of two adjacent partition blocks 23 cooperate to clamp the test battery 10, thus fixing the test battery 10 and ensuring its stable and reliable installation on the tray 20. Furthermore, the partition blocks 23 can slide relative to the connecting rod 22 in the left-right direction, meaning the spacing between adjacent partition blocks 23 can be adjusted according to the size of the test battery 10 to clamp it, making the use of the partition blocks 23 more flexible and convenient. The partition blocks 23 are detachably connected to the connecting rod 22 via fasteners, thus securing the partition blocks 23.

[0052] In one embodiment, please refer to the reference Figure 1 The frame 21 is detachably connected to the insulation board 24.

[0053] By using an insulation plate 24 to keep the test battery 10 inside the tray 20 warm, the efficiency of vacuum drying is improved. Furthermore, the insulation plate 24 is detachably connected to the frame 21, facilitating replacement of the insulation plate 24 after wear, making its use more flexible and convenient.

[0054] In one embodiment, please refer to the reference Figure 1 The connection structure also includes a heat insulation cover, which is placed outside the temperature measuring instrument 30 and connected to the tray 20.

[0055] The heat insulation cover is installed and fixed by connecting to the tray 20. The heat insulation cover is placed over the thermometer 30 to insulate the thermometer 30 from heat. Since the temperature is very high during vacuum drying, the heat insulation cover is set to insulate the thermometer 30 from heat, so as to prevent the thermometer 30 from being damaged due to excessive temperature, improve the safety and reliability of the thermometer 30, and extend the service life of the thermometer 30.

[0056] External devices include a processor, and memory can be used to store software programs and various data. The memory can primarily consist of a program storage area and a data storage area. The program storage area can store the operating system, at least one application program required for a function (such as real-time reception of audio and video data sent by the server), etc.; the data storage area can store data or information created based on the use of the terminal. Furthermore, the memory can include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device.

[0057] The processor is the control center of the terminal. It connects various parts of the terminal via various interfaces and lines, and performs various functions and processes data by running or executing software programs and / or modules stored in memory, and by calling data stored in memory, thereby providing overall monitoring of the terminal. The processor may include one or more processing units; preferably, the processor may integrate an application processor and a modem processor, wherein the application processor mainly handles the operating system, user interface, and applications, while the modem processor mainly handles wireless communication. It is understood that the modem processor may also not be integrated into the processor.

[0058] although Figure 1 Not shown, but the aforementioned external device may also include a circuit control module, which is used to connect to the mains power supply to realize power control and ensure the normal operation of other components.

[0059] Additionally, please refer to the following: Figure 3 The present invention also provides a temperature measurement method based on the furnace temperature measuring device 100 described above. The furnace temperature measuring device 100 refers to the above embodiments. Since the temperature measurement method adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0060] Temperature measurement methods include:

[0061] Step S10: The furnace temperature measuring device performs a self-check and initializes its working information;

[0062] Step S20: The furnace temperature measuring device enters the cavity station;

[0063] The furnace temperature measuring device can be moved into the cavity workstation using a handling device, such as a stacker crane, forklift, or other handling device.

[0064] Step S30: Perform temperature measurement according to preset conditions, and obtain temperature measurement data and test report;

[0065] Step S40: Automatically save the output test data and test report.

[0066] The system automatically saves output test data and test reports to facilitate operators in retesting or repairing unqualified test batteries 10.

[0067] In step S50, the furnace temperature measuring device sequentially enters the next cavity station and initializes the environmental conditions for temperature measurement until all cavity stations have completed temperature measurement.

[0068] The furnace temperature measuring device sequentially enters the next chamber station and initializes the environmental conditions to measure the temperature of the next chamber station until all chamber stations are measured. This enables furnace temperature testing of multiple chamber stations in a single furnace to ensure the consistency of the baking temperature of the lithium battery vacuum drying system. It also enables initial temperature verification under full load conditions in the early stage of vacuum drying equipment production and rapid temperature verification during battery replacement.

[0069] In one embodiment, please refer to the reference Figure 4 Step S30 involves measuring the temperature according to preset conditions and obtaining the temperature data and test report, including:

[0070] Step S31: Preset the heating time and preset temperature according to the type of test battery 10 and the baking process;

[0071] Step S32: After the preset heating time is achieved, the actual temperature of multiple temperature probes inside the multiple test batteries 10 is obtained;

[0072] Each test battery 10 is equipped with multiple temperature probes to measure the temperature at multiple locations within the test battery 10. The actual temperatures of the multiple temperature probes within the multiple test batteries 10 in the tray 20 are obtained.

[0073] Step S33: Calculate the difference between the actual temperature of each temperature probe and the preset temperature based on the actual temperature of the multiple temperature probes.

[0074] After the temperature probe measures the actual temperature, it transmits the measured temperature information to the wireless transmitter through the temperature measurement channel. The wireless receiver of the external device works in conjunction with the wireless transmitter to conduct the data transmission circuit, which is used to transmit the temperature information of the test battery 10. The external device is a computer, which processes the temperature information. Based on the actual temperature of the temperature probe, the difference between the actual temperature and the preset temperature is calculated. Each test battery 10 is equipped with multiple temperature probes, and multiple test batteries 10 are arranged in the tray 20. The difference between the actual temperature of each temperature probe and the preset temperature is calculated one by one.

[0075] Step S34: When the difference between the actual temperature and the preset temperature is greater than the preset tolerance range, a non-conforming report is generated; when the difference between the actual temperature and the preset temperature is less than or equal to the preset tolerance range, a conforming report is generated.

[0076] In this embodiment, the preset temperature is set to 90℃, and the preset tolerance range is set to ±3℃. When the difference between the actual temperature of the temperature probe and the preset temperature is greater than the preset tolerance range, a non-conforming report is generated to facilitate the operator to retest or repair the non-conforming cavity workstation. When the difference between the actual temperature and the preset temperature is less than or equal to the preset tolerance range, a conforming report is generated. Multiple temperature probes are installed in each test battery 10, and multiple test batteries 10 are installed in the tray 20. The difference between the actual temperature of each temperature probe and the preset temperature is calculated one by one to ensure that the temperature at each location within the cavity workstation is within the preset tolerance range, thus ensuring temperature uniformity at each location within the cavity workstation.

[0077] In one embodiment, please refer to the reference Figure 1 and Figure 5 Step S32, the step of obtaining temperature information of multiple test batteries 10, includes:

[0078] Step S321: Obtain the quantity parameter of test batteries 10;

[0079] Step S322: Arrange multiple test batteries 10 into a temperature measurement matrix unit according to the number parameter of test batteries 10;

[0080] Based on the obtained quantity parameters of the test batteries 10, the multiple test batteries 10 in the tray 20 are arranged into temperature measurement matrix units. The temperature measurement matrix units can be 2×2, 3×3, 4×4 or other quantities. If the cavity work area of ​​the single furnace is large, the number of test batteries 10 is relatively large, and the temperature measurement matrix units can be relatively large; if the cavity work area of ​​the single furnace is small, the number of test batteries 10 is relatively small, and the temperature measurement matrix units can be relatively small.

[0081] Step S323: Obtain the temperature information of the temperature measurement matrix unit.

[0082] The temperature information of the temperature measurement matrix unit is obtained as the temperature information of the test battery 10 in the entire cavity station, thereby improving the temperature measurement efficiency and reliability.

[0083] In other embodiments, multiple test batteries 10 can be evenly distributed. Specifically, sampling points can be set at the center and four corners of the tray 20, and the temperature information of the test batteries 10 obtained from these sampling points can be used as the temperature information of the test batteries 10 for the entire cavity. Alternatively, multiple sampling points can be set at other locations on the tray 20, and the temperature information of the test batteries 10 obtained from these sampling points can be used as the temperature information of the test batteries 10 for the entire cavity.

[0084] In one embodiment, please refer to the reference Figure 1 Each test battery 10 contains three temperature probes, which are evenly distributed at the bottom, middle and top of the axis of the inner electrode center plane of the test battery 10.

[0085] In this embodiment, each test battery 10 contains three temperature probes, which are evenly distributed at the bottom, middle, and top of the centerline of the inner electrode surface of the test battery 10. Each temperature probe is sequentially numbered using Arabic numerals or letters, corresponding to the temperature measurement channel of the thermometer. This avoids insufficient quantity to verify the internal temperature uniformity of the test battery 10, thus improving the reliability of the measurement results. At the same time, it also avoids increased cost due to excessive quantity.

[0086] In other embodiments, the number of temperature probes in each test battery 10 can be flexibly adjusted to other numbers according to actual needs. The present invention does not limit the number of temperature probes in each test battery 10.

[0087] Furthermore, the present invention also provides a computer-readable storage medium for storing a computer program, wherein the computer program, when executed by a processor, implements the temperature measurement method as described above. This temperature measurement method refers to the above embodiments. Since the computer-readable storage medium adopts all the technical solutions of the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here.

[0088] The above are merely preferred embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural transformations made under the concept of the present invention using the description and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
