Description

Technical Field

[0001] The invention relates to a motor winding machine, in particular to a motor winding machine capable of automatically detecting a winding starting position of an iron core winding. Background Art

[0002] At present, brushless motors with position magnetic sensors are relatively common in the electric vehicle industry. Therefore, when the motor core enters the automated winding process, an operator or external detection equipment is required to match the position sensor on the core with the starting position of the winding before the winding procedure can begin. Otherwise, if the starting position is wrong, the product will be scrapped. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides a motor winding machine which can automatically detect the starting position of the iron core winding.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a motor winding machine that automatically detects the starting position of the core winding, including a machine body and an iron core, a sinker and a magnetic position sensor embedded in the sinker are provided on the iron core, and also includes a motion controller, a metal sensor and a sensor motion mechanism. The metal sensor is moved and positioned by the sensor motion mechanism, and the metal sensor receives the motion controller signal and moves to the outer edge of the iron core. The metal sensor detects the position of the rotating iron core magnetic position sensor and outputs high and low level signals to the motion controller. The motion controller stops detection by continuously receiving two or more signals, and then rotates the iron core to the winding starting position according to the set program, thereby automatically completing the iron core winding starting position detection program.

[0005] The magnetic position sensor is a Hall sensor.

[0006] At least two sensing probes of the metal sensor correspond to the positions of the iron core and the magnetic position sensor, and the sensing probes of the metal sensor are arranged along the axial direction of the iron core.

[0007] The installation dimensions of the magnetic position sensor are 4 mm in length×4.1 mm in width×1.6 mm in height, and the magnetic position sensor is fixed by glue or a circuit board.

[0008] The motion controller is a PLC programmable logic controller, a GMC motion controller, a DMC motion controller or a PC bus motion controller.

BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 It is a schematic diagram of the structure of the present invention. DETAILED DESCRIPTION

[0011] like Figure 1 As shown, a motor winding machine for automatically detecting the winding starting position of the core 1 winding includes a machine body and a core 1, wherein the core 1 is provided with a sinking platform and a magnetic position sensor embedded in the sinking platform, and further includes a motion controller, a metal sensor 2 and a sensor motion mechanism 3, wherein the metal sensor 2 is moved and positioned by the sensor motion mechanism 3, and the metal sensor 2 receives the motion controller signal and moves to the outer edge of the core 1, wherein the metal sensor 2 detects the rotating core 1 and outputs high and low level signals, and the motion controller stops the detection by continuously receiving two or more signals, and then rotates the core to the winding starting position according to the set program, thereby automatically completing the core winding starting position detection program. The sensor motion mechanism 3 may be a cylinder structure, which is determined by actual production and will not be explained in detail here.

[0012] Working Overview: After pressing the start button, the motion controller sends a signal to the metal sensor 2 motion cylinder, and moves the metal sensor 2 close to the outer edge of the iron core 1; then the iron core 1 starts to rotate at the preset rotation speed and direction, and stops detecting when the motion controller receives two or more high and low level signals continuously within the preset number of turns; then the iron core is rotated according to the preset number of turns and direction and stops. At this time, the iron core 1 just stops at the starting position of winding, and the next winding program can be entered.

[0013] The magnetic position sensor is a Hall sensor. The Hall sensor is a magnetic field sensor made according to the Hall effect. The Hall effect is a kind of magnetoelectric effect. The Hall effect of semiconductors is much stronger than that of metals. Various Hall elements made by this phenomenon are widely used in industrial automation technology, detection technology and information processing. The metal sensor 2 has at least two induction probes corresponding to the iron core 1 and the magnetic position sensor position. At least two induction probes of the metal sensor 2 are arranged in the axial direction of the iron core 1, one of which corresponds to the installation position of the magnetic position sensor distributed on the iron core 1, and the other corresponds to the iron core 1 adjacent to the installation position of the magnetic position sensor on the iron core 1. At this time, the metal sensor 2 outputs a high and low level at the same time. When the winding machine motion controller receives the signal twice, it will determine whether to enter the next step according to the preset program until it meets the standard of the preset program and enters the next winding action. In short, at least two induction probes of the metal sensor 2, one corresponds to the sinker and the other corresponds to the iron core 1. When the iron core 1 rotates, the relative position of the Hall can be found.

[0014] The installation dimensions of the magnetic position sensor are 4 mm long × 4.1 mm wide × 1.6 mm high, and the magnetic position sensor is fixed by glue or a circuit board. This is a specific implementation method, not the only limitation. In addition, this structure is easy to install, firm and stable.

[0015] The motion controller is a PLC programmable logic controller, a GMC motion controller, a DMC motion controller or a PC bus motion controller. The above controller programs are different but can achieve the same action. In practice, all of the above controllers can be used without being limited to any one.

[0016] In the description of the present invention, it should be noted that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. At the same time, the basic principles, main features and advantages of the present invention are shown and described above, which should be understood by technicians in this industry.
