Magnetic pole detecting machine of linear motor

Abstract

The invention provides a magnetic pole detecting machine of a linear motor. The detecting machine comprises a carrying platform and a detecting mechanism arranged at the upper side of the carrying platform. The carrying platform moves back and forth between an initial loading position and a detection position below the detecting mechanism. A positioning mechanism for locating a stator of a linearmotor is arranged on the carrying platform. In addition, the detecting mechanism also includes an X-axis electric cylinder, a Z-axis electric cylinder, a Y-axis cylinder and a magnetic pole sensor. The magnetic pole sensor is driven by the Z-axis electric cylinder to move up and down back and forth along the Z axis; the Z-axis electric cylinder and the magnetic pole sensor arranged on the Z-axis electric cylinder are driven by the X-axis electric cylinder to reciprocate left and right; and the Y-axis cylinder drives the carrying platform to reciprocate front and back along a slide rail arranged in a Y-axis direction. The motion range of the magnetic pole sensor covers the area of the positioning mechanism on the carrying platform. With the three-axis detecting mechanism and the magnetic pole sensor, the magnetic poles on the stator of the linear motor can be detected one by one, so that the actual detection requirement of industrial production is met.

Description

technical field [0001] The invention relates to a linear motor magnetic pole detector, in particular to a device for detecting the magnetic pole quality of a stator of a linear motor. Through detection, it can determine the continuity and directionality of the coil winding, that is, whether the phase sequence of the product winding is correct and whether there is a disconnection, thereby ensuring the product yield. Background technique [0002] At present, the magnetic pole confirmation test is required in the production process of the stator (primary) of the linear motor. This test is often used before and after injection molding of the stator of the linear motor (sealed as a whole with epoxy resin). The purpose is to confirm the conduction performance of the coil winding, that is, whether the winding coil is connected correctly). When testing, by switching any two-phase power lines and passing a certain current (according to the technical characteristics of the product, a...

Problems solved by technology

[0003] Specifically, the current detection method is to manually use a magnetic pole detection pen to detect a single block one by one. The disadvantage is that the detection efficiency is low and error-prone, so it cannot meet the detection needs of industrial production.
