Shifting unit for pole set assembly line

Abstract

The invention relates to the field of automatic assembly lines, in particular to a shifting unit for a pole set assembly line. The shifting unit comprises a cam, a shifting rod, a spring and a pin, wherein the cam and a rotary shaft are concentrically arranged and rotate synchronously; a head matched with the cam and a tail hitting permanent magnets are arranged on the shifting rod; a slide way accommodating the permanent magnets is arranged on the shifting unit; the shifting unit can enable the spring to trigger the shifting rod rapidly after energy storage by the aid of the cam, and the shifting rod enables single permanent magnet to fly into a clamping jaw of a rotary table by hitting the permanent magnet. The cam and the rotary shaft rotate synchronously, and the shifting rod is matched with notches of the cam, so that the mechanical linkage performance is good, an operator can adjust and control a complete set of systems without the language programming skill, and the maintenance cost is low. The invention further provides an assembly line comprising the shifting unit.

Description

technical field [0001] The invention relates to the field of automatic assembly lines, in particular to a material shifting unit used in a magnetic pole group assembly production line. Background technique [0002] Patent document PCT / CN2014 / 081921 discloses a magnetic energy turntable, which is equipped with numerous magnetic pole group arrays, each magnetic pole group is composed of 16 pieces of permanent magnets arranged alternately with adjacent magnetic poles, and each magnetic pole group is artificially Due to the small size and thin thickness of each permanent magnet, manual assembly is difficult, inefficient, and error-prone, resulting in multiple permanent magnets attracting each other. In order to improve efficiency and eliminate time loss caused by errors, the factory adopts an automated assembly line to assemble the magnetic pole groups. The shifting unit in the assembly line is driven by a cylinder or a linear motor, and a laser position switch is used to judge ...

[0002] Patent document PCT / CN2014 / 081921 discloses a magnetic energy turntable, which is equipped with numerous magnetic pole group arrays, each magnetic pole group is composed of 16 pieces of permanent magnets arranged alternately with adjacent magnetic poles, and each magnetic pole group is artificially Due to the small size and thin thickness of each permanent magnet, manual assembly is difficult, inefficient, and error-prone, resulting in multiple permanent magnets attracting each other

In order to improve efficiency and eliminate time loss caused by errors, the factory adopts an automated assembly line to assemble the magnetic pole groups. The shifting unit in the assembly line is driven by a cylinder or a linear motor, and a laser position switch is used to judge the position of a single permanent magnet. The PLC control unit is used to control the ejection of a single permanent magnet. Although such a material pulling unit realizes the required functions, the maintenance cost of the whole set of units is high, programming control is required, the complexity is high, and the operator’s electrical and electronic skills are required. Assembly line The large magnetic field composed of permanent magnets on the PLC has certain interference to the PLC electronic circuit
