[0002] Lithium-ion battery modules, as a crucial component of new energy systems, are receiving increasing attention. Steel strapping, a simple, efficient, and low-cost process, is gradually becoming a mainstream method in the market. A common method for strapping battery modules with steel strapping involves placing end plates matching the shape of the individual cells at both ends of the stacked cells. After squeezing the end plates together, rectangular steel strapping is applied to the end plates, thereby confining all the cells between the end plates. Therefore, the length of the steel strapping must provide both longitudinal spacing and a certain degree of binding force for the module; therefore, ensuring the accuracy of the steel strapping is crucial.

[0003] Existing patent CN109099868A discloses a steel strip length measuring device for lithium-ion power battery module assembly auxiliary equipment. The device base of the power battery module steel strip length measuring device is provided with a guide rail, and a front slider and a rear slider are provided on the guide rail.

Component 10, the width positioning component 10 includes a groove-shaped positioning plate 101 with an opening facing downward, a limit block 102 is provided on the inner side of the positioning plate 101, a spring 103 is provided inside the limit block 102, and a limit button 104 is provided on the top of the spring 103. The limit button 104 is limitedly matched with the zipper-type adjustment hole 105 provided on the positioning plate 101. A laser rangefinder 11 is provided between the two width positioning components 10 on the fixing seat 7, and the laser detection direction of the laser rangefinder 11 is toward the two width positioning components 10 on the adapter block 5.

[0022] Specifically, the power end of the bearing screw 8 can be a hand wheel or an electric motor; the bearing screw 8 is used to drive the movable seat 4 and the fixed seat 7 to produce a relative distance, the actual test distance is controlled by the laser rangefinder 11, and the pressure sensor 6 is used to test the group force and feed back to the digital display instrument 9. Regarding the width positioning assembly 10, the relative width position of the positioning plate 101 on the fixed seat 7 and the adapter block 5 remains unchanged; the limit block 102 is a structure that directly contacts the strapping tape 12. By adjusting the matching position of the limit button 104 and the zipper-type adjustment hole 105, the actual combined length of the limit block 102 and the positioning plate 101 can be adjusted, thereby controlling the combined length of the two width positioning assemblies 10 in the same width direction, thereby achieving the purpose of adjusting the actual test width of the strapping tape 12, thereby improving its adaptability to battery cells of different specifications, and helping to reduce test errors. This device has a reasonable design, simple structure, and can accurately complete the measurement of the length of the module steel strip. At the same time, it can adapt to a variety of width sizes to improve the versatility of the device and facilitate personnel operation, which can effectively reduce investment costs, has strong practicality and high utilization rate.

[0023] In order to improve the adjustment performance of the positioning plate 101 and the limiting plate, the zipper-type adjustment hole 105 provided in the utility model includes a straight-line segment 1051, and a plurality of spaced-apart column hole segments 1052 are provided on the straight-line segment 1051. The limiting button 104 includes a limiting segment 1041 cooperating with the column hole segment 1052. The top of the limiting segment 1041 is provided with a through-hole segment 1042 smaller than its diameter, and the top of the through-hole segment 1042 is provided with a handle segment 1043. Among them, under the support of the spring 103, the top surface of the limiting section 1041 is higher than the plate surface of the positioning plate 101, and is stuck in the column hole section 1052, and will not slide with the I-shaped section 1051; the diameter of the through-hole section 1042 is the same as the radial width of the I-shaped section 1051. By pressing the handle section 1043, the limiting section 1041 can be pressed below the positioning plate 101, and by shifting the handle section 1043, the through-hole section 1042 can be translated along the I-shaped section 1051. Loosening the handle section 1043 allows the limiting section 1041 to enter the corresponding column hole section 1052, thereby realizing the adjustment of the actual combined length of the positioning plate 101 and the limiting plate, thereby effectively realizing the adjustment of the test width of the strapping tape 12.

[0024] In order to improve the stability of the limit block 102 under the test pressure, the limit block 102 provided by the present invention includes a main body 1021 nested with the positioning plate 101, and an end head 1022 for cooperating with the strapping tape 12 is provided at the end of the main body 1021. The end face corners of the end head 1022 are rounded, and the end head 1022 and the main body 1021 form a T-shaped structure. The two sides of the main body 1021 are in contact with the inner wall of the positioning plate 101 to prevent the head from shaking, and the end head 1022 is in smooth contact with the turning part of the strapping tape 12, which can ensure the cooperation performance of the width positioning component 10 and the strapping tape 12, and is conducive to improving the testing effect of the present device.

[0025] In order to improve the adjustment balance of the strapping strap 12 in the length direction, the present invention provides a micro-adjustment slot inside the slider 3. The micro-adjustment slot is provided with a fixed balance plate 31 and an adjustment balance plate 32 that are relatively distributed in a gate shape. The adjustment balance plate 32 is provided with a positioning hole 33 and an offset hole 34. The positioning hole 33 and the offset hole 34 are respectively provided with a positioning pin and a countersunk screw. The positioning pin and the countersunk screw do not contact the top surface of the guide rail. An armature 35 for leveling is provided between the adjustment balance plate 32 and the micro-adjustment slot. The armature 35 is a thin plate with a certain wedge angle. It is inserted between the adjustment balance plate 32 and the micro-adjustment slot. It can make the adjustment balance plate 32 slightly deflect around the center of the positioning hole 33 and the positioning pin, and the countersunk screw and the offset hole 34 have a slight deviation. This compensates for the deflection angle between the slider 3 and the guide rail 2 caused by processing errors and assembly factors, improves the balance of the slider 3 moving along the guide rail 2, and thus improves the testing performance of the strapping strap 12 of the present device.
