Tension testing device and automatic assembling equipment

Abstract

The invention discloses a tension testing device and automatic assembling equipment, and the tension testing device comprises: a jig assembly which is used for clamping a workpiece; a positioning assembly which is used for clamping and positioning the workpiece needle bar; a first power assembly which is used for driving the positioning assembly to get close to or away from the workpiece needle bar; a needle pulling assembly which is located above the workpiece and used for clamping and upwards pulling the workpiece steel needle; and a second power assembly which is used for driving the needle pulling assembly to ascend or descend. After glue of the needle rod and the steel needle is solidified, a workpiece is placed in the jig and cannot move, then the first power assembly drives the positioning assembly to move towards and clamp the needle rod, the second power assembly drives the needle pulling assembly to move downwards and clamp the steel needle, then the needle pulling assembly moves reversely to pull the steel needle upwards, and if the steel needle is not pulled, the steel needle is inspected to be qualified. Therefore, manual work is replaced by machinery, the working efficiency is effectively improved, the working intensity of workers is reduced, fatigue operation is avoided, the consistency of mechanical operation is good, the consistency of drawing force is ensured, missed detection of workpieces is prevented, and the product quality is ensured.

Description

technical field [0001] The invention relates to the technical field of tensile testing, and more specifically, relates to a tensile testing device and automatic assembly equipment. Background technique [0002] Tattoo needle is one of the commonly used tools in beauty, tattoo and other industries. It is mainly composed of back cover, needle rod, silicone cap, steel needle, outer cover and so on. When assembling, the needle bar is inserted into the back cover and both ends protrude out of the back cover, then put on the silicone cap, dispense glue into the inner hole at the upper end of the needle bar, then insert the steel needle into the needle bar, and bond the two with glue Secure, then put on the cover. Among them, after the glue is cured, it is generally necessary to perform a pull-out test to check whether the steel needle and the needle bar are firmly bonded. However, in the prior art, manual inspection is mainly adopted, which has high labor intensity and low work ...

Problems solved by technology

However, in the prior art, manual inspection is mainly used, which has high labor intensity and low work efficiency. After working for a long time, workers are prone to misoperation, which affects the quality of finished products.
