[0049] The working principle of the battery cell extrusion thickness measuring mechanism is introduced in this embodiment. Before measurement, two groups of battery cells to be measured are respectively placed between the first moving plate and the first fixed plate, and between the second moving plate and the second fixed plate. During measurement, the actuator starts to work, the telescopic rod extends to drive the second moving plate to move to the left, and the second moving plate pushes a group of battery cells to the second fixed plate. When the battery cells are clamped and kept stable by the second moving plate and the second fixed plate, the telescopic rod continues to extend, the force of the telescopic rod acts on the mounting plate and pushes the mounting plate to move to the right in the opposite direction. The mounting plate moving to the right drives the first moving plate to move to the right at the same time through the first moving rod and the second moving rod, and pushes another group of battery cells to the first fixed plate. When the battery cells are clamped and kept stable by the first moving plate and the first fixed plate, the thickness measuring device works to read the thickness of the two battery cells. At the same time, the value of the pressure sensor is obtained to obtain the pre-pressing force of the two battery cells. After the measurement is completed, the telescopic rod is retracted, the mounting plate drives the first moving plate to reset to the left and returns to the preset position through the limiting assembly, and the telescopic rod drives the second moving plate to reset to the right and returns to the preset position through the limiting assembly.

[0050] When the size of the battery cell changes, the same moving plate and fixed plate can be added to increase the height limit of the measurable battery cell and widen the length limit of the measurable battery cell.

[0051] Compared with the ordinary battery cell thickness measurement, the thickness of two groups of battery cells is measured at the same time, and the battery cells are pre-pressed, so that the efficiency of battery cell production is improved. Through the design of the connecting hole, the demand for adapting to various models of battery cells is met, and the efficiency of the production line is well satisfied. The waste of resources is avoided, and the market value is high, which is worth popularizing.

[0052] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary technical personnel in the technical field, without departing from the principle of the present application, a number of improvements and refinements can be made, and these improvements and refinements should be regarded as the protection range of the present application.
