Description

Technical Field

[0001] The utility model belongs to the technical field of battery separator thickness measurement, in particular to a battery separator thickness gauge. Background Art

[0002] The separator is one of the main components of the battery. Its main function is to prevent the positive and negative electrodes from short-circuiting, but it cannot significantly increase the internal resistance of the battery. The quality of the separator directly affects the discharge capacity and charge-discharge cycle life of the battery. Therefore, the porosity, pore size, thickness and uniformity, wettability, and folding resistance of the battery separator must be strictly controlled.

[0003] During the processing of battery separators, it is essential to detect their thickness. However, the existing battery separator thickness detection is mostly performed manually using a thickness detector. To ensure the accuracy of the detection, the battery separators are mostly repeatedly detected. However, the use of a thickness detector for measurement has many steps, which not only leads to manual measurement errors, but also causes low worker efficiency and difficulty in comparison, making battery separator detection more inconvenient.

[0011] The limiting mechanism is arranged at the lower end of the adjustment plate and is used to make the ultrasonic transmitter fit tightly against the battery separator.

[0012] Furthermore, the clamping mechanism includes a clamping member, a second conveying shaft, a connecting member and a reset spring. The clamping member is fixed on the upper end surface of the support frame, the second conveying shaft is rotatably connected to the inner side of the clamping member, the connecting member is fixed on the upper end surface of the main frame, the reset spring is arranged inside the connecting member, and the other end of the reset spring is in contact with the clamping member.

[0013] Furthermore, the outer shapes and structures of the conveying shaft 1 and the conveying shaft 2 are consistent, and the conveying shaft 1 and the conveying shaft 2 maintain the same vertical center line.

[0014] Furthermore, a scale is evenly fixed on the lower end surface of the outer surface of the clamping member, and the clamping member can be slid up and down along the inside of the connecting member for adjustment.

[0015] Furthermore, the limiting mechanism includes a limiting rod and an extrusion spring. The limiting rod is symmetrically fixed on the lower end surface of the adjustment plate, and the limiting rod can be slid up and down along the inside of the support plate for adjustment.

Since the return spring can pull the clamping member downward to squeeze, and cooperate with the scale to perform a preliminary detection of the thickness of the battery separator, if the thickness of the battery separator changes, the corresponding value of the scale is different, which can provide a reference for the staff.

[0019] 2. The utility model can push the fixed plate downward by arranging an extrusion spring, so that the ultrasonic transmitter at the lower end of the fixed plate can contact the top of the battery separator, so that the ultrasonic transmitter and the ultrasonic receiver can correspond to each other, which can facilitate the subsequent display of the thickness value.

[0031] The outer shapes and structures of the conveying shaft 1 4 and the conveying shaft 2 6 are consistent, and the conveying shaft 1 4 and the conveying shaft 2 6 maintain the same vertical center line.
