Description

Technical Field

[0001] The utility model relates to the technical field of rotor detection line screening materials, in particular to a screening material separation device for a new energy vehicle motor rotor detection line. Background Art

[0002] The rotor of a brushless DC motor is composed of permanent magnets with a certain number of pole pairs embedded on the surface of the iron core or embedded inside the iron core. Permanent magnets are mostly made of rare earth permanent magnet materials with high coercivity and high permeability magnetic induction density, such as neodymium iron boron. During the production and processing of the rotor of a brushless DC motor, in order to improve the production accuracy of the rotor, it is necessary to perform optical inspection on the rotor surface. After the rotor inspection, the rotor with problems on the surface needs to be screened and separated. The current screening method is to manually separate the motor rotor that fails the inspection from the inspection device, which is time-consuming and labor-intensive, has low operating efficiency, and also affects the inspection accuracy. Utility Model Content

[0005] The lower surface of the top screening frame is provided with a bottom assembly frame protruding downwards.

[0006] The electrically controlled flip separation arm comprises an arc-shaped flip adjustment arm movably assembled inside a bottom assembly frame, a main electrically controlled adjustment support rod for controlling the arc-shaped flip adjustment arm, a flip limit arm movably assembled at the notch end at the bottom of the arc-shaped flip adjustment arm, and an electromagnet and an iron extrusion spring installed inside the notch at the bottom of the arc-shaped flip adjustment arm.

[0007] A strip-shaped telescopic opening is provided inside the top material screening frame.

[0008] A transverse bottom guide rail is fixed on the lower surface of the top screening frame at the bottom opening position of the strip-shaped telescopic opening, and an elastic buffer mechanism is elastically assembled inside the transverse bottom guide rail.

[0010] The beneficial effects of the utility model are:

[0011] (1) The screening and separation device for the new energy vehicle motor rotor testing line of the utility model can directly separate the motor rotors that fail the test by flipping, without affecting the normal conveying and testing of the motor rotors;

[0012] (2) The stability and anti-loosening performance of the rotor can be improved by electronically controlled flipping and top electromagnetic control;

[0013] (3) By setting an elastic buffer mechanism on the top screening frame, the impact force of the rotor after separation can be reduced, thereby improving the safety of screening separation;

[0014] (4) Under normal conditions, the bottom space can be increased by flipping the electrically controlled flip separation arm upward without affecting normal transportation;

[0019] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] Figure 1 and Figure 2The screening and separation device for the new energy vehicle motor rotor detection line shown in the figure includes a main frame 2 with a bottom electric-controlled conveyor belt 1 installed inside, a bottom support seat 3 for loading the motor rotor is fixed on the outer side of the bottom electric-controlled conveyor belt 1, a top screening frame 4 is fixedly installed inside the main frame 2 above the bottom electric-controlled conveyor belt 1, an electric-controlled flip separation arm 5 is movably installed inside the top screening frame 4, and a bottom separation groove 6 matching the electric-controlled flip separation arm 5 is opened on the upper surface of the bottom support seat 3.

[0022] The bottom electrically controlled conveyor belt 1 is a prior art, and drives the top screening frame 4 to move on the main frame 2 through movement.

[0023] In order to cooperate with the bottom movable assembly, the lower surface of the top screening frame 4 has a bottom assembly frame protruding downward.

[0024] In order to cooperate with the electric-controlled flip adjustment and electromagnetic-controlled flip, the electric-controlled flip separation arm 5 includes an arc-shaped flip adjustment arm 51 movably assembled inside the bottom assembly frame, a main electric-controlled adjustment support rod 52 for controlling the arc-shaped flip adjustment arm 51, a flip limit arm 53 movably assembled at the bottom notch end of the arc-shaped flip adjustment arm 51, an electromagnet 54 installed inside the bottom notch of the arc-shaped flip adjustment arm 51, and an iron extrusion spring 55.

[0025] The main electrically controlled adjusting strut 52 and the electromagnet 54 are both prior arts. The main electrically controlled adjusting strut 52 controls the flipping of the arc-shaped flip adjusting arm 51 by extending and retracting. The electromagnet 54 is started to control the iron extrusion spring 55 to drive the flip limiting arm 53 to flip and adjust. Then, the arc-shaped flip adjusting arm 51 and the flip limiting arm 53 are inserted from the bottom separation slot 6. Then, the rotor is separated from the top screening frame 4 from the bottom of the rotor, and the rotor is lifted onto the arc-shaped flip adjusting arm 51. Then, the electromagnet 54 is powered off, and the iron extrusion spring 55 squeezes the flip limiting arm 53 to flip upward. Then, one side of the rotor is limited to prevent it from falling off, thereby improving safety.

[0026] In order to cooperate with the internal sliding adjustment, a strip-shaped telescopic opening is opened inside the top screening frame 4.

[0027] In order to cooperate with internal assembly and elastic buffering, a horizontal bottom guide rail 7 is fixed to the lower surface of the top screening frame 4 at the bottom opening position of the strip-shaped telescopic opening, and an elastic buffer mechanism 8 is elastically assembled inside the horizontal bottom guide rail 7.

[0028] In order to cooperate with elastic buffering, the elastic buffering mechanism 8 includes a transverse guide rod 81 fixed inside the transverse bottom guide rail 7, an internal translation slider 82 slidably assembled on the outside of the transverse guide rod 81, an arc-shaped limit frame 83 fixed on the outer surface of the internal translation slider 82, and a transverse spring 84 sleeved on the outside of the transverse guide rod 81.

[0029] When the motor rotor is introduced from the flip limit arm 53 to the top screening frame 4 and then rolls and impacts the elastic buffer mechanism 8, the rotor is then buffered by the transverse spring 84.

The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
