[0034] The working principle is:

[0035] The manipulators at other workstations place the cells in the area to be measured of the cell thickness measuring device 2 , and the thickness measuring device starts working to record the cell thickness data.

[0036] After the measurement is completed, the triple robot 3 clamps the battery cell from the thickness measuring device and transfers it to the width compression measuring device 1 for width measurement.

[0037] During the measurement process, if the cell is judged to be NG material (unqualified product), the NG sorting robot 4 will take it out of the measuring device and transfer it to the designated NG material box 5. On the contrary, if it is OK material (qualified product), it will be transferred to the OK material box 5.

[0038] The entire measurement and sorting process is automated, greatly improving work efficiency and measurement accuracy.

[0039] like Figure 2As shown, in this embodiment, the width compression measuring device 1 includes a CCD camera module 11, a measuring placement platform 12, a constant force micrometer 13 and a baffle device 14. The CCD camera module 11 is arranged on the measuring placement platform 12, and the constant force micrometer 13 and the baffle device 14 are relatively arranged on the measuring placement platform 12. The measuring placement platform 12 is used to place the battery cell, and the constant force micrometer 13 is used to press the battery cell onto the baffle device 14, and obtain the width of the battery cell through the CCD camera module 11.

[0040] The constant force micrometer 13 can maintain a constant pressure during the measurement process, pressing the battery cell gently and stably against the baffle device 14 .

[0041] like Figure 2 As shown, in this embodiment, the baffle device 14 includes an adjustment seat 141, an adjustment guide rail 142, and a locking assembly 143.

The locking assembly 143 is used to lock the adjusted adjustment seat 141 on the adjustment guide rail 142. The design of the baffle device 14 takes into account the flexibility and stability of adjustment. By sliding the adjustment seat 141 on the adjustment guide rail 142, the distance between the baffle 1412 and the battery cell can be conveniently adjusted to accommodate battery cells of different specifications.

[0042] like Figure 2 As shown, in this embodiment, a mounting groove 1411 is provided on the side of the adjustment seat 141 corresponding to the constant force micrometer 13. A baffle 1412 is provided in the mounting groove 1411. The surface of the baffle 1412 that contacts the battery cell is a first contact surface a. After the flatness of the first contact surface is adjusted, the baffle 1412 is locked in the mounting groove 1411. The mounting groove 1411 on the adjustment seat 141 is used to accurately install the baffle 1412, and by adjusting the flatness of the first contact surface of the baffle 1412, uniform force is ensured on the contact surface with the battery cell.

[0043] like Figure 2 As shown, in this embodiment, the locking assembly 143 includes a locking block 1431 and a locking connecting plate 1432. The locking block 1431 is disposed at the end of the adjustment rail 142 near the constant force micrometer 13. The side surface of one end of the locking connecting plate 1432 is mounted on one side of the end surface of the adjustment seat 141. The locking connecting plate 1432 is provided with a locking groove 1433, which corresponds to the locking block 1431. The locking connecting plate 1432 is threadedly connected to the locking block 1431 via bolts passing through the locking groove 1433. The locking assembly 143 utilizes the locking block 1431 and the locking connecting plate 1432 in combination, and is fastened by bolts to achieve precise positioning and locking of the adjustment seat 141 on the adjustment rail 142, thereby preventing positional deviation during measurement.

[0044] like Figure 3 As shown, in this embodiment, the battery cell thickness measuring device 2 includes a transverse platform 21, at least one set of thickness test modules 22, and at least one set of transverse platforms 23. The transverse platform 23 is set on the transverse platform 21, and the thickness test module 22 is set on one side of the transverse platform 21.

The transverse platform 21 is driven by a high-precision servo motor 223, which can smoothly and accurately transfer the battery cell from the material collection position to the bottom of the thickness test module 22.

[0045] like Figure 3 As shown, the dust removal device 24 is arranged on one side of the transverse platform 21 to remove dust and impurities on the surface of the battery cell by blowing or suctioning to ensure the accuracy of the measurement results.

[0046] like Figure 4 As shown, in this embodiment, the thickness test module 22 includes a pressure plate 221, a slide 222, a motor 223, a pull rope 224, and a guide wheel 225, which enable the lifting and lowering motion of the pressure plate 221. The motor 223, through a transmission system consisting of the pull rope 224 and guide wheel 225, drives the slide 222, which in turn drives the pressure plate 221 downward at a constant speed. After contact with the battery cell surface, the thickness is measured. The pressure plate 221 is made of marble due to its high hardness, low coefficient of expansion, and excellent flatness, which helps improve measurement accuracy.

[0047] like Figure 4 As shown, in this embodiment, a displacement sensor is installed on the slide 222 to detect the height of the pressure plate 221 in real time and transmit the data to the control system for calculating the thickness of the battery cell.
