manipulator

Abstract

The invention discloses a mechanical hand which is used for implanting a nut. The mechanical hand comprises a rack, a grabbing mechanism, a slide mechanism, a power mechanism and a return mechanism. In production operation, the nut is grabbed by the grabbing mechanism, and the nut is kept to not drop under clamping action of a first clamping plate and a second clamping plate. The power mechanism drives a slide plate to slide in a slide slot, drives an ejector pin to get out of a limiting hole, and ejects out the grabbed nut to implant into a target element. After implanting is completed, the power mechanism stops applying force to the slide plate, and the slide mechanism is returned under action of an elastic part of the return mechanism. The grabbing mechanism continuously grabs a next nut to enter next implanting operation, so that continuous and automatic production is realized, and implanting efficiency is improved. The ejector pin slides and is stable in a return process, so that the nut is prevented from the defects such as floating or sinking, and therefore, the implanting effect is relatively good.

Description

technical field [0001] The invention relates to the technical field of automation equipment, in particular to a manipulator for implanting nuts. Background technique [0002] Nuts are commonly used in the process of product assembly. For example, multiple nuts need to be set in the middle frame of a mobile phone to connect other components. There are two common production methods for implanting nuts into the middle frame of mobile phones. The first method is to manually bury the nuts in the hot-melt plastic mold of the middle frame of the mobile phone, and then inject plastic parts. This production method The manual operation is slow, the labor cost is high, and the injection temperature is high, the working environment is poor, and production accidents are prone to occur. The second method is to inject the plastic part first, and then use a hot-melt tool (such as a hot-melt machine) to melt the nut into the plastic part. This production method is prone to defects such as f...

There are two common production methods for implanting nuts into the middle frame of mobile phones. The first method is to manually bury the nuts in the hot-melt plastic mold of the middle frame of the mobile phone, and then inject plastic parts. This production method Manual operation is slow, labor costs are high, and the injection temperature is high, the working environment is poor, and production accidents are prone to occur

The second method is to inject the plastic parts first, and then use a hot-melt tool (such as a hot-melt machine) to melt the nuts into the plastic parts. This production method is prone to defects such as nuts floating or sinking.

[0003] In summary, the traditional way of implanting nuts in the middle frame of mobile phones is inefficient and poor in implantation effect
