Automatic screening machine

Abstract

The invention discloses an automatic screening machine. The automatic screening machine is characterized in that one side of a screw positioning push block is provided with a clamping groove for containing screws, one side surface of the screw positioning push block closely props against a feeding channel outlet of a feeder, and the feeding channel outlet of the feeder is capable of aligning with the clamping groove of the screw positioning push block; an idler wheel group comprises a pair of idler wheels which are rotated in the same direction, an imaging device is positioned right above the idler wheel group, and the idler wheel group is positioned in an imaging region of the imaging device; a material taking device is capable of conveying the screws in the clamping groove of the screw positioning push block to the middle position of the idler wheel group and conveying the screws of the middle position of the idler wheel group to the material receiving device, and the material taking device can be positioned on a rack in a rotating manner; material boxes are respectively arranged below the two sides, which are perpendicular to a revolving shaft, of the imaging device transmits information to a controller, and the controller controls the movements of the material receiving device, the material taking device and the screw positioning push block. The automatic screening machine provided by the invention has the advantages that the structure is simple, the screening speed is rapid, and the screening accuracy rate is high.

Description

technical field [0001] The invention relates to a workpiece detection and screening device, in particular to an automatic screening machine. Background technique [0002] In the screw processing industry, it is necessary to inspect and screen the appearance of screws. At present, the screening of screws mainly depends on manual visual inspection. The screening accuracy is low and the speed is slow, and it is easy for unqualified products to mix into the qualified product area. Contents of the invention [0003] In order to make up for the above deficiencies, the present invention provides an automatic screening machine, which can quickly complete the screening action of screws, with fast screening speed, high production efficiency and high screening accuracy. [0004] The technical scheme adopted by the present invention in order to solve its technical problems is: an automatic screening machine, including a frame, a roller group, a feeder, a screw positioning push block, ...
