A loading and unloading system for an injection molding machine

Abstract

The invention discloses a loading and unloading system of an injection molding machine, which comprises a frame, on which are provided a receiving device for receiving finished plastic parts, a sheet conveying device for conveying metal connecting sheets, and a device for conveying semi-finished plastic parts. The feeding device and the manipulator, the manipulator is equipped with a number of clamping stations that can respectively clamp metal connecting pieces, semi-finished plastic parts and finished plastic parts. Different clamping stations on the manipulator can respectively clamp metal connecting pieces and semi-finished plastic parts. The parts are fed into the injection molding machine, and the finished plastic parts after injection molding can be taken out and transferred to the receiving device. When the finished plastic parts are placed on the tray, the transfer group can adjust the space on the empty tray to receive the finished plastic parts. The application effectively solves the problem of simultaneously picking and placing multiple workpieces, reduces the complexity of the loading and unloading system, and improves the loading and unloading efficiency of the loading and unloading system.

Description

technical field [0001] The invention relates to the technical field of injection molding equipment, in particular to a loading and unloading system. Background technique [0002] At present, automotive sensors generally form semi-finished plastic parts first, and then combine them with metal connecting pieces through secondary injection molding to obtain the final product. Due to the different shapes of metal connectors, semi-finished plastic parts and finished plastic parts, most of the injection molding industry uses manual loading, resulting in high labor costs, low work efficiency, high labor intensity, and prone to work-related injuries. [0003] For this reason, some enterprises have designed manipulators for loading materials, but most of the existing injection molding machines use multiple manipulators to hold different workpieces for feeding, because the shapes of metal connecting pieces, semi-finished plastic parts and finished plastic parts are different. , which...

Problems solved by technology

Due to the different shapes of metal connecting pieces, semi-finished plastic parts and finished plastic parts, most of the injection molding industry uses manual loading, resulting in high labor costs, low work efficiency, high labor intensity, and prone to work-related injuries.

[0003] For this reason, some enterprises have designed manipulators for loading materials, but most of the existing injection molding machines use multiple manipulators to hold different workpieces for feeding, because the shapes of metal connecting pieces, semi-finished plastic parts and finished plastic parts are different. , which makes it difficult for the same manipulator to hold different types of workpieces for feeding at the same time. Only multiple sets of manipulators can be used to hold different workpieces for feeding. Such a design often leads to a large space occupation and the entire cost investment. The loading and unloading position space is limited, resulting in multiple manipulators having to move in sequence, and the overall work efficiency is still unsatisfactory.

Moreover, in the process of unloading after the manipulator clamps the finished plastic parts, generally the existing palletizing devices are in a fixed position. In order to ensure that the finished plastic parts can be arranged in a certain order, only by controlling the unloading manipulator to continuously Adjusting one's own feeding position to adapt to the requirements of the plate placement requires adjustment of the control system of the entire feeding manipulator, so that the feeding position of the finished plastic parts can be arranged in an orderly manner, which is convenient for later identification and use by other equipment. Obviously it will complicate the whole control system
