Description
Technical field
The utility model is related to the detection devices of stator lasmination, it is especially useful in detect the direction of stator lasmination.
Background technology
In vehicle manufacture, motor is highly important component.The stator of motor is generally configured laminated construction, by more
A stator piece being stamped and formed out is laminated on together, and stator lasmination is consequently formed.
When assembling motor, it is necessary to assure stator lasmination is in correct direction.For this purpose, being arranged on the front of stator lasmination
Pit.Fig. 1 shows the stator lasmination 10 ' in correct direction, its upper surface (front) is provided with circular pit at this time
11’.Meanwhile needing that detection device is arranged in assembling line, whether the direction for detecting stator lasmination is correct.
Fig. 1 shows a kind of traditional detection device 1 ', including machine assembly 20 ' and the control unit for operating connection therewith
30’.Machine assembly 20 ' is arranged in the top of stator lasmination 10 ' and includes the multiple mechanical probes 21 ' for being arranged in bottom.For
The direction of detection stator lasmination, detection device 1 ' further includes mobile mechanism 40 ', fixed to make probe 21 ' move down contact
The upper surface of sub- lamination.If probe 21 ' detects the presence of pit 11 ', show that stator lasmination is in correct direction, otherwise
Stator lasmination is in the direction of mistake.But this mechanical detection device is not easy that (star or annular are folded according to stator lasmination
Piece) it is adjusted, it usually needs it takes a long time to adjust the detection device, and detection is unstable, especially detects star
When shape stator lasmination.
A kind of improved detection device is had developed in recent years, and above-mentioned machine assembly is replaced with camera.As shown in Fig. 2,
The detection device 1 " includes camera 20 " and operates the control unit 30 " of connection therewith.Camera 20 ' is arranged in stator lasmination
10 " top whether there is circular pit 11 " with the upper surface of the stator lasmination 10 " of detection lower section.Camera 20 " has
Visual range G can only detect the stator lasmination surface in specific region.In order to adjust the detection range of camera 20 ", detection dress
It sets 1 " and is optionally also provided with mobile mechanism 40 ", be used for dollying head 20 ".Therefore, this detection device 1 " is also not easy root
It is adjusted according to stator lasmination, and still unstable, when especially detecting star stator lasmination.
Moreover, because pit 11 ' exists only in the positive specific region of stator lasmination, so only stator lasmination 10 "
It is in scheduled angle around its longitudinal axis when loading in place, camera 20 " can just detect pit 11 ".If stator stack
Piece is not in scheduled angle, it is necessary to which stator lasmination is turned to scheduled angle by operating personnel, otherwise the vision of camera
Range does not cover pit, so whether the direction that stator lasmination can not be detected is correct.In practice, operating personnel always need to turn
Dynamic stator lasmination.
Invention content
In view of the prior art above-mentioned detection device the shortcomings that, improved be used for stator the utility model proposes a kind of
The detection device of lamination is easy to be adjusted, and can steadily detect the direction of stator lasmination.
The detection device of the utility model includes light emitting source, optical receiver, and is operated respectively with light emitting source and optical receiver
The control unit of connection.Light emitting source sends out the peripheral surface that illumination is mapped to stator lasmination (star or annular lamination), optical receiver
Receive reflected light, whether control unit determines less than the predetermined threshold value in optical receiver according to the performance of the reflected light received
Whether stator lasmination is in correct direction.If be less than predetermined threshold value, it is determined that stator lasmination towards mistake, if instead
Reach threshold value, it is determined that the direction of stator lasmination is correct.Predetermined threshold value can be preset luminous intensity or brightness.
The design of the utility model is, since stator lasmination is made of punching press, therefore there are flash directions so that from stator stack
The reflected light of the positive and negative both sides of piece is different.The detection device of the utility model can be with perception reflex light, to determine stator stack
The direction of piece.
Embodiment according to the present utility model, optical receiver are luminance sensor, and predetermined threshold value is luminance threshold.
Embodiment according to the present utility model, light emitting source and optical receiver are integrated into a sensor.
Preferably, detection device further includes alarm unit, operates and connects with control unit.Control unit is in reflected light
Brightness activates alarm unit when being less than predetermined threshold value, notify operating personnel's stator lasmination towards mistake,
The structure of the detecting device of the utility model is simple, eliminates the complicated mechanical probe structure of existing detection device
With expensive camera system, and the direction of stator lasmination can be steadily detected.Moreover, no matter stator lasmination is loading just
What angle is in when position, detection device can determine the direction of stator lasmination, this is convenient for adjusting.In addition, used
Optical sensor is much lower compared to camera system cost, and readily replaceable when failure.
From the following specifically describes and attached drawing, the other feature and advantage of the utility model will be evident.
Description of the drawings
The embodiments of the present invention will be explained in further detail in the accompanying drawings, shown in the drawings of：
