Feeding device for taking and placing materials through air pressure change

Abstract

The invention relates to a feeding device for taking and placing materials through the air pressure change. The feeding device aims to solve the problems that inserting head and inserting piece clamping locating precision and efficiency are low, and the surface is scratched easily. The feeding device is composed of a feeding mechanical hand, a loading tray and a locating jig. The loading tray andthe locating jig are located on the two sides of the feeding mechanical hand correspondingly. The feeding mechanical hand comprises a drive carrying portion and a vertical taking and placing portion.The vertical taking and placing portion can move between the loading tray and the locating jig under driving of the drive carrying portion. The vertical taking and placing portion is composed of an installing support, an air cylinder, a guide rail, a sliding block, a sliding bottom plate and a vacuum sucking disc. The installing support is fixed to the drive carrying portion. The air cylinder is supported on the installing support. The sliding bottom plate is installed on the installing support in a sliding manner through the guide rail and the sliding block and moves up and down under controlling of the air cylinder. The vacuum sucking disc is fixed to the sliding bottom plate. The vacuum sucking disc is provided with a vacuum air way and a positive pressure air way. The vacuum air way isconnected continuously. The positive pressure air way is controlled by an electromagnetic valve to be connected or disconnected.

Description

technical field [0001] The invention belongs to the field of numerical control automation, and in particular relates to a feeding device for taking and discharging materials through changes in air pressure. Background technique [0002] The plug blade structure usually includes three parts: the front protruding blade head, the rear protruding terminal pin and the middle spacer. . Since the front protruding insert needs to cooperate with the socket, the dimensional accuracy is very high. If the dimensional accuracy is not up to standard, it will affect the normal use or cause problems such as poor contact. However, due to the small size of the plug insert itself, loading and unloading and positioning and clamping are relatively difficult. At present, when the front protruding insert head is finished, the single plug insert is manually inserted into the corresponding positioning jig.

AI Technical Summary

Problems solved by technology

Since the front protruding insert needs to cooperate with the jack, the dimensional accuracy is very high. If the dimensional accuracy is not up to standard, it will affect normal use or cause problems such as poor contact.

However, due to the small size of the plug insert itself, loading and unloading and positioning and clamping are relatively difficult. At present, when the front protruding insert head is finished, the single plug insert is manually inserted into the corresponding positioning jig. On the one hand, this clamping and positioning method is difficult to control the insertion force and direction by manual operation, it is difficult to achieve high positioning accuracy, and it is easy to cause scratches on the surface of the workpiece; High volume and low price production requirements
