Description

Technical Field

[0001] This utility model relates to a soft-pack lithium battery molding equipment, and in particular to a spectral thickness measurement mechanism on a soft-pack lithium battery molding equipment. Background Technology

[0002] The thickness of the battery seal edge is a crucial parameter in the production of pouch lithium batteries, and the accuracy of thickness measurement directly affects the processing parameters of the battery seal edge. The traditional method for measuring the thickness of the battery seal edge is contact measurement.

[0003] Currently, contact measurement commonly employs equipment such as coordinate measuring machines (CMMs), probe-type height gauges, or digital dial indicators on dedicated stands. However, when measuring thickness, the probes or probes of CMMs and probe-type height gauges touch the surface of the battery seal edge, applying a certain measuring force to complete the measurement. This creates indentations on the battery seal edge, affecting its appearance and causing measurement damage. Furthermore, CMMs and similar devices are not dedicated thickness measuring instruments; their functions are complex, and their design is redundant. While they can perform some thickness measurements, their accuracy is difficult to reach sub-micron levels. Additionally, when using digital dial indicators with dedicated stands to measure thickness, the manual measurement is significantly affected by human factors and the dial indicator's accuracy, limiting the overall accuracy to the micron level. Summary of the Invention

One side of the connecting plate is fixed on the lifting slide plate, and the other side is provided with a plurality of waist-shaped holes at intervals. The adjustment mounting base is fixed on the column, and the adjustment mounting base is provided with a Z-axis adjustment micrometer. The Z-axis adjustment micrometer is connected to the bottom of the connecting plate. The column is provided with a positioning pin corresponding to the position of each of the waist-shaped holes, and the positioning pin passes through the waist-shaped hole.

[0011] As an improvement of the spectral thickness measurement mechanism in the soft-pack lithium battery molding equipment of this utility model, the moving control mechanism includes a module profile, one end of which is provided with a motor base, a servo motor is provided on the motor base, the output shaft of the servo motor is connected to a transmission screw through a coupling, a screw nut is screwed onto the transmission screw, the screw nut is connected to a moving slide plate, the moving slide plate is connected to the column, the moving slide plate is slidably connected to the module profile through a slide rail and a slider, and the module profile is installed on the base.
