AI Technical Summary

Technical Problem

In the existing technology, the blank clamping fixture is prone to physical damage or separation of the adsorption surface from the blank during the clamping process, resulting in low product yield and low production efficiency.

Method used

A material preform adsorption fixture was designed, including a fixed base, an adsorption component, a rotating shaft, and a drive component. By using multi-point adsorption and angle adjustment, the adsorption area is increased, and stable adsorption is achieved by using a negative pressure chamber and a negative pressure hole to prevent the material preform from detaching.

Benefits of technology

It improves the clamping stability of the blank and the continuity of the conveying process, reduces blank scrap and production stoppage, and improves product yield and production efficiency.

Abstract

The utility model relates to blow molding plastic automobile fuel tank production, and discloses a blank adsorption tool which comprises a fixed seat, an adsorption assembly, two rotating shafts and two driving assemblies, one end of the fixed seat is arranged at the end of a mechanical arm of a robot, and the adsorption assembly is arranged at the other end of the fixed seat. The adsorption assembly comprises a first adsorption block, a second adsorption block and a third adsorption block which are sequentially arranged in the length direction of the blank, the two rotating shafts are arranged at the two ends of the second adsorption block correspondingly, and the ends, close to the second adsorption block, of the first adsorption block and the third adsorption block are hinged to the corresponding rotating shafts correspondingly; the two driving assemblies are arranged on the sides, away from the blank, of the first adsorption block and the third adsorption block correspondingly and used for being matched with the rotating shaft to drive the first adsorption block and the third adsorption block to rotate towards the blank. The blank adsorption tool can effectively prevent the blank from stripping due to external vibration, inertia force and other factors in the conveying process, and the blank clamping and conveying stability is improved.
