Lithium batteries include battery cells and protection circuit boards. Battery cells are usually pole pieces of fixed length. In the process of preparing battery cells, mark holes (cutting identification holes) are used to mark the pole pieces. The pole piece between two mark holes is a battery cell, and the two mark holes are the starting position and the end position of the battery cell. Currently, when testing the size of the battery cell, the pole piece between the two mark holes is manually cut from the pole piece, and the size of the pole piece is measured offline with a soft ruler to obtain the size of the battery cell.

[0003] However, manual interception and measurement is not only time-consuming, but also causes equipment shutdown in the battery cell preparation process. Long-term equipment shutdown will damage production capacity and reduce production efficiency.

[0062] Lithium batteries have the characteristics of high energy storage density and high production quality requirements, so they are widely used in daily life. Lithium batteries include battery cells and protection circuit boards. Battery cells are usually pole pieces of fixed length. In the process of preparing battery cells, mark holes (cutting identification holes) are used to mark the pole pieces. The pole piece between two mark holes is a battery cell, and the two mark holes are the starting position and the end position of the battery cell. Currently, when testing the size of the battery cell, the pole piece between the two mark holes is manually cut from the pole piece, and the size of the pole piece is measured offline with a soft ruler to obtain the size of the battery cell.

[0063] However, manual interception and measurement is not only time-consuming, but also causes equipment downtime. Long-term equipment downtime will damage production capacity and reduce production efficiency.

[0064] In order to alleviate the problem of time-consuming and production efficiency-affecting manual interception and measurement of material size in the related art, an embodiment of the present application provides a material measuring device, which includes a tape measure, an adapter plate, a first winding assembly mounted on the adapter plate, a second winding assembly, a first tensioning assembly, and a second tensioning assembly; one end of the tape measure is arranged on the first winding assembly, and the other end of the tape measure is connected to the second winding assembly after passing through the first tensioning assembly and the second tensioning assembly, and the first winding assembly and the second winding assembly can drive the tape measure to unwind from one of the first winding assembly and the second winding assembly and wind on the other. The first tensioning assembly and the second tensioning assembly enable the tape measure to be tensioned and transmitted between the first winding assembly and the second winding assembly, so that when the material measuring device is used to measure the pole piece in the battery cell preparation process, the tape measure in the material measuring device can be used to directly measure the size of the pole piece between the two mark holes, without manually intercepting the pole piece and then measuring it, which not only improves the measurement efficiency, but also reduces the impact of manual measurement on the battery cell preparation process because the equipment in the battery cell preparation process does not need to be shut down.

[0065] The material measuring device in the embodiment of the present application includes, but is not limited to, being applied to the measurement of electrodes, paper, cloth and other materials to be tested.

For example, it can be used in electric vehicles to power the motors of electric vehicles as a power source for electric vehicles. The battery can also power other electrical devices in electric vehicles, such as in-car air conditioners, car players, etc.

[0067] like Figure 1 As shown, the material measuring device may include:

[0068] A measuring tape 11, an adapter plate 12, a first winding assembly 13 installed on the adapter plate 12, a second winding assembly 14, a first tensioning assembly 15 and a second tensioning assembly 16;

[0069] One end of the measuring tape 11 is arranged on the first winding assembly 13, and the other end of the measuring tape 11 is connected to the second winding assembly 14 after passing through the first tensioning assembly 15 and the second tensioning assembly 16. The first winding assembly 13 and the second winding assembly 14 can drive the measuring tape 11 to unwind from one of the first winding assembly 13 and the second winding assembly 14 and wind it onto the other.

[0070] In this embodiment, the first winding assembly 13 and the second winding assembly 14 can both be used as a winding assembly and an unwinding assembly. For example, the first winding assembly 13 is a winding assembly and the second winding assembly 14 is an unwinding assembly. In this case, the second winding assembly 14 can unwind the tape measure 11 wound on the second winding assembly 14 and drive the tape measure 11 to transfer to the first winding assembly 13, and the first winding assembly 13 is used to wind up the tape measure 11. For another example, the second winding assembly 14 is a winding assembly and the first winding assembly 13 is an unwinding assembly.

[0075] In the solution provided in this embodiment, the first winding assembly, the second winding assembly, the first tensioning assembly and the second tensioning assembly are arranged in a quadrilateral structure on the adapter plate. Compared with the colinear structure, the space occupied by the first winding assembly, the second winding assembly, the first tensioning assembly and the second tensioning assembly can be relatively reduced.

[0125] Step 401, in response to detecting a detection signal of a material to be detected, obtaining a first tape measure scale and a second tape measure scale on the tape measure, wherein the first tape measure scale corresponds to a first cutting identification hole on the material to be detected, and the second tape measure scale corresponds to a second cutting identification hole on the material to be detected;

[0126] Step 402: Calculate the size of the material to be inspected between the first cutting identification hole and the second cutting identification hole based on the first tape measure scale and the second tape measure scale.

[0127] It should be understood that the size of the material to be detected between the first cutting identification hole and the second cutting identification hole may be the scale difference between the first tape measure scale and the second tape measure scale.
