Rapid adjusting device for probe assembly of lithium battery forming and capacity grading equipment

Abstract

The invention relates to a rapid adjusting device for a probe assembly of lithium battery forming and capacity grading equipment. The device comprises electricity leading bases, sliding contact lines,a sliding contact line insulating base, sliding contact line brush heads, flexible wires, a probe assembly and a horizontal position fixing and adjusting structure of the probe assembly. The slidingcontact line insulating base is provided with a plurality of sliding grooves which are arranged up and down. The sliding contact lines are fixedly arranged in the sliding grooves. The sliding contactline brush heads are arranged in the sliding grooves in a sliding mode, and are in sliding electrical contact with the sliding contact lines. The sliding contact line brush heads are electrically connected with the probe assembly through the flexible wires. The electricity leading bases are arranged at the ends of the sliding contact line insulating bases, and are used for achieving connection between the sliding contact lines and an external high-current cable. An electricity passing mode combining the sliding contact lines and the sliding contact line brush heads is adopted. Because the sliding contact line brush heads can move on the sliding contact lines, when the probe assembly is moved, the sliding contact line brush heads can move along with the probe assembly, the bending of a copper core wire and the accumulation of surplus wires are avoided during adjustment, and the position adjustment is more convenient and quicker.

Description

technical field [0001] The present invention relates to the technical field of lithium battery manufacturing equipment, in particular to a quick adjustment device for a probe assembly of lithium battery formation and capacity measuring equipment. Background technique [0002] When the lithium battery is divided into capacity, a large current needs to be passed between the positive and negative electrodes of the battery. Usually, the forming current needs to reach 60A, and the capacity-dividing current needs to reach 120A, or even more than 200A. Such a large current will inevitably make the wires and terminals carrying the current They are very thick and not easy to bend, which makes it difficult to move and adjust the position of the probe assembly connected to it. The probe assembly cannot be quickly aligned with the positive and negative poles of the battery. Even if the position movement and adjustment are barely satisfied, the general Under normal circumstances, each pr...

[0002] When the lithium battery is divided into capacity, a large current needs to be passed between the positive and negative electrodes of the battery. Usually, the forming current needs to reach 60A, and the capacity-dividing current needs to reach 120A, or even more than 200A. Such a large current will inevitably make the wires and terminals carrying the current They are very thick and not easy to bend, which makes it difficult to move and adjust the position of the probe assembly connected to it. The probe assembly cannot be quickly aligned with the positive and negative poles of the battery. Even if the position movement and adjustment are barely satisfied, the general Under normal circumstances, each probe assembly is fixed by two screws. Due to the poor thickness and flexibility of the wires, the seat force of the probe assembly is large, which will make it difficult to install the screws, and the return of the probe is not flexible, which is time-consuming and labor-intensive.
