Embodiment Construction

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0030] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other indicated orientations...

Abstract

The invention provides a battery helium detection clamping mechanism which comprises a base, a positioning assembly for positioning a battery, an upper sealing assembly for sealing and pressing a battery, a helium injecting assembly for injecting helium to the battery, and a first power assembly for providing power for movement of the helium injecting assembly. The positioning assembly, the uppersealing assembly and the helium injecting assembly are arranged on the base; a positioning chamber for positioning the battery is arranged on the positioning assembly; a push block is arranged on theouter part of the positioning chamber; and an elastic piece capable of being abutted against the upper sealing assembly when the battery is sealed through the upper sealing assembly is arranged at oneend of the push block. According to the battery helium detection clamping mechanism, the push block and the elastic piece are arranged at one end of the battery, so that the magnitude of the sealingpressure of a helium injection port is controlled, and the sealing performance of the helium injection part is ensured under the circumstance of guaranteeing that the battery is non-deformed.

Description

technical field [0001] The invention belongs to the field of clamps, and in particular relates to a battery helium test clamping mechanism. Background technique [0002] At this stage, the consumer electronics market is growing steadily, especially with the rise of the smart watch industry, resulting in an increasing demand for small and medium-sized thin-walled steel-cased batteries. The steel shell of this kind of battery is relatively thin, generally less than 0.1mm. At present, in the process of battery production and inspection, battery manufacturers often deform the workpiece due to excessive sealing pressure of the helium injection port or cause tightness due to too small sealing pressure of the helium injection port. Not good, helium leaks, causing false detection. Contents of the invention [0003] The purpose of the present invention is to provide a battery helium detection and clamping mechanism to solve the technical problems existing in the prior art that the...
