[0041] In one embodiment of this utility model, such as Figure 1-4As shown, a lithium battery cell thickness measuring machine is provided, including: a detection area 1, a positioning platform 2, a pressure plate 3, a pressure sensor 4, and a measurement sensor 5. The detection area 1 is a working area for detecting the thickness of lithium battery cells; the positioning platform 2 reciprocates along the direction of the detection area 1, and is used to carry and transport lithium battery cells to the detection area 1; the pressure plate 3 is disposed above the detection area 1 and moves up and down along the height direction of the detection area 1, and is used to apply pressure to the lithium battery cells on the positioning platform 2; the pressure sensor 4 is installed on the pressure plate 3 and is used to detect the pressure value applied by the pressure plate 3 to the lithium battery cells; the measurement sensor 5 is installed on the side of the pressure plate 3 and is used to detect the thickness of the lithium battery cells under pressure; when the positioning platform 2 moves to the detection area 1, the pressure plate 3 synchronously approaches the positioning platform 2 along a movement trajectory adapted to the positioning platform 2 and applies a preset pressure to the lithium battery cells on it; the measurement sensor 5 detects the thickness data of the lithium battery cells under pressure in real time during the pressure application process and after the pressure stabilizes.

[0042] The lithium battery cell thickness measuring machine provided by this utility model transports the lithium battery cell to the detection area 1 through the positioning platform 2. The pressure plate 3 applies pressure synchronously along the preset trajectory, the pressure sensor 4 monitors the pressure in real time, and the measurement sensor 5 detects the thickness synchronously. This enables the lithium battery cell to complete the thickness detection under the preset pressure, realizing the coordinated operation of automated pressure application and measurement, thereby improving the detection efficiency and the accuracy of the thickness data, and ensuring the stability and reliability of the detection process.

[0043] The lithium battery cell thickness measuring machine also includes a first direction drive component 6, which is connected to the positioning platform 2 for driving the positioning platform 2 to reciprocate along the direction of approaching or moving away from the detection area 1.

[0044] Specifically, the first direction drive component 6 includes a lateral drive source 601 and a lateral track 602. The positioning platform 2 is slidably connected to the lateral track 602, and the output end of the lateral drive source 601 is connected to the positioning platform 2 to drive it to reciprocate along the lateral track 602.

[0045] The first directional drive component 6, which is composed of the lateral drive source 601 and the lateral track 602, is connected to the positioning platform 2 and drives it to move back and forth along the track. This enables the positioning platform 2 to stably and accurately transport lithium battery cells to the detection area 1, thereby ensuring the stability and positional accuracy of the lithium battery cell transport process and improving the automation level and detection efficiency of the equipment.

[0046] Furthermore, by placing the lithium battery cell on the positioning plate 7 on the top surface of the positioning platform 2, the lithium battery cell maintains a stable posture during transportation and testing, avoiding deviation, thereby ensuring accurate pressure application and measurement, and improving the reliability of the test data.

[0047] Furthermore, the detection distance sensor 8 installed at the initial position of the positioning platform 2 acquires the lithium battery cell placement position data in real time, enabling timely detection of position deviations, thereby ensuring accurate positioning of the lithium battery cell and improving detection reliability.

[0048] The lithium battery cell thickness measuring machine also includes a second direction drive component 9, which is connected to the pressure plate 3 and is used to drive the pressure plate 3 to reciprocate along the direction of raising or lowering the detection area 1.

[0049] Specifically, the second direction drive component 9 includes a longitudinal drive source 901 and a longitudinal track 902. The pressure plate 3 is slidably connected to the longitudinal track 902, and the output end of the longitudinal drive source 901 is connected to the pressure plate 3 to drive it to reciprocate along the longitudinal track 902.

[0050] The second-direction drive assembly 9, consisting of the longitudinal drive source 901 and the longitudinal track 902, drives the pressure plate 3 to move precisely up and down along the track, allowing the pressure plate 3 to stably approach or move away from the positioning platform 2 and accurately apply preset pressure. The pressure application process is controllable, avoiding pressure deviation, thereby ensuring the stability of the lithium battery cell under pressure and improving the accuracy of thickness detection and the reliability of equipment operation.

[0051] The lithium battery cell thickness measuring machine also includes a barcode scanner 10. The barcode scanner 10 in front of the detection area 1 obtains the lithium battery cell identification information, so that the detection data is accurately associated with the identity, realizes information traceability, thereby improving data management efficiency and ensuring product quality traceability.

[0052] It also includes a display 11 and an alarm 12. The pressure sensor 4 and the measuring sensor 5 are both electrically connected to the display 11, which is used to display pressure and thickness data.

[0053] In this embodiment, a thickness tester display panel 13 and a pressure display panel 14 can also be installed to display thickness data and pressure data respectively.

[0054] The lithium battery cell thickness measuring machine also includes a machine base 15, which is installed at the bottom of the detection area 1. The machine base 15 is used to install the positioning platform 2, the pressure plate 3, the pressure sensor 4, and the measurement sensor 5.

[0055] In this embodiment, a protective cover 16 and a safety barrier can be installed to make the equipment safer to operate, thereby ensuring operational safety.

[0056] The usage process of this utility model is as follows:

[0057] 1) The lithium battery cell whose thickness needs to be measured is manually placed onto the positioning platform 2 and positioned;

[0058] 2) Scan the QR code or barcode on the battery with a barcode scanner, and the data will be automatically entered into the industrial control computer;

[0059] 3) Confirm that the detection distance sensor 8 (radio photoelectric sensor) has detected that the lithium battery cell has been placed in place;

[0060] 4) Press the start button with both hands. The positioning platform 2 moves to the detection area 1 and stops. The pressure plate 3 is pressed down to the set stroke by the second direction drive component 9. The pressure plate 3 comes into contact with the surface of the lithium battery cell and is pressurized to the set value (e.g., the set value is 300KG, which can be read and displayed on the panel by the pressure sensor 4) and held for a certain time (e.g., the set value is 1.5s). The end of the measuring sensor 5 contacts the surface of the marble pressure plate 3 and the data is fed back to the system to obtain the thickness value of the measured lithium battery cell and the current pressure value. The data is automatically entered into the industrial control computer and stored. The data can be exchanged with the user's MES system.

[0061] 5) The equipment test data is displayed in real time on the monitor 11. The equipment will automatically alarm and prompt for the thickness of defective lithium battery cells, and is equipped with audible and visual alarm prompts.

[0062] 6) After the test is completed, the pressure plate 3 rises to the safe position, the positioning platform 2 returns to the loading station, and the lithium battery cell is manually removed to complete the thickness measurement function.
