Automatic riveting process and device for reversely reckoning manipulator insert based on drawing force

Abstract

The invention discloses an automatic riveting process and device for reversely reckoning a manipulator insert based on drawing force. The device comprises a mold ejector sleeve needle, a material taking nozzle, a steel ball, a round silica gel sleeve, an ejector pin, a hanging table and a pen-shaped cylinder, the pen-shaped cylinder is in threaded connection with the hanging table, the hanging table is movably connected with the ejector pin through a T-shaped groove, the ejector pin is in sliding fit connection with concentric circles in the material taking nozzle, and the mold ejector sleeveneedle is in transition fit connection with a nut in the material taking nozzle. The dependence of the combination firmness of the nut and a plastic part on the trademark of raw material is reduced, the labor cost is reduced, automatic unmanned operation is achieved, and the excellent yield is achieved.

Description

technical field [0001] The invention relates to the technical field of 3C manufacturing, in particular to an automatic riveting process and device for manipulator inserts based on reverse calculation of pulling force. Background technique [0002] With the improvement of people's quality of life, the quality requirements of products are getting higher and higher, and new processes are constantly being introduced. For the nuts of plastic parts, the conventional practice is to use the excellent thermal conductivity of copper nuts to heat copper nuts after injection molding. The hot copper nut slowly melts into the hollow plastic column, and after cooling, the copper nut and the plastic part are fused together. This method has the following disadvantages: 1. Due to the different grades of raw materials of plastic parts, the physical properties and melting properties of the plastic parts heated twice will be different, resulting in different bonding firmness with copper nuts. T...

Problems solved by technology

This method has the following disadvantages: 1. Due to the different grades of raw materials of plastic parts, the physical properties and melting properties of the plastic parts heated twice will be different, resulting in different bonding firmness with copper nuts. Test the firmness of copper nuts by means of testing. For example, the conventional method is to detect the pulling torque, and the defect rate remains high; 2. After the nail is embedded after forming, it needs to be placed manually. Now the personnel are not easy to manage, the products produced are mixed, and the rework rate is high
