A rapid adjustment mechanism for the distance between a probe module and a formed needle bed

Abstract

The invention discloses a probe module interval rapid adjusting mechanism and a formation needle bed, and the probe module interval rapid adjusting mechanism comprises an upper layer frame, a probe fixing frame, a pressing assembly and a positioning and adjusting tool. An upper guide rail and an installation frame are separately arranged on the two opposite sides of the upper layer frame, and theinstallation frame is provided with a through groove arranged in the same direction as the upper guide rail; two ends of the probe fixing frame are respectively connected to the corresponding upper guide rails in a sliding manner; the pressing assembly comprises an ejector rod movably mounted on the probe fixing frame and in the through groove in a sliding manner, a pressing plate which is connected to the periphery of the ejector rod and located between the installation frame and the probe fixing frame, and an elastic piece which sleeves the ejector, is elastically supported between the pressing plate and the installation frame, and drives the pressing plate to press the probe fixing frame through an elastic force so that the probe fixing frame can be locked on the upper layer frame; andthe positioning and adjusting tool jacks up the ejector rod under the effect of a jacking mechanism, so that the probe fixing frame is in an unlocked state capable of freely sliding in the through groove. The formation needle bed can adjust the positions of multiple groups of probe fixing frames at the same time, and has the advantages of high adjusting efficiency and low labor intensity.

Description

technical field [0001] The invention relates to the technical field of lithium battery testing, in particular to a rapid adjustment mechanism for the spacing of a probe module and a forming needle bed. Background technique [0002] With the wide application of square aluminum case lithium-ion batteries in the new energy power industry, the new energy industry has stricter high standards for the quality and consistency of square aluminum case batteries. [0003] The existing lithium battery testing equipment includes a lower frame structure and an upper frame structure located above the lower frame structure and supported by preset guide rods. The lower frame structure is equipped with a rough positioning platform for placing the full-load lithium battery pack tray. The upper frame structure is equipped with multiple sets of probe modules arranged horizontally and horizontally. The probe modules include probe holders and probe holders. There are multiple probe assemblies use...
