Abstract
The utility model discloses a light curtain protector for an AOI instrument. The light curtain protector is characterized by comprising an emitter, a lens device, a reflecting barrier and at least two receivers. The emitter emits a one-way light beam. The lens device is arranged on the outer side of the emitter and transmits the light beam in a divergence mode. The reflecting barrier is arranged on the front side of the AOI instrument and is parallel to the emitter and symmetrical with the emitter. The receivers are arranged on the left side and the right side of the emitter respectively, and the light beam which is transmitted in the divergence mode is reflected back to the receivers through the reflecting barrier. According to the light curtain protector, the light beam emitted by the emitter is transmitted in the divergence mode through the lens device and reflected back to the receivers through the reflecting barrier, as a result, the range of areas where the light beam emitted by the emitter passes is expanded, the safety protection range is greatly expanded, detection accuracy is high, input of the emitter can be reduced, cost of a light curtain device is reduced, and the area, occupied by the light curtain protector, of the light curtain device is small.
Description
Technical field
The utility model relates to the protective gear of AOI detection facility, specifically refers to the light curtain protective gear for AOI detection facility.
Background technique
Along with AOI detection facility automaticity is more and more higher, safety problem more and more receives publicity.In order to protect operator's safety, light curtain protective gear becomes an important device of AOI detection facility safety protection.Light curtain protective gear is to be formed by the optical transmitting set and the optical receiver that are vertically mounted on before front, AOI detection facility working area or working robot's periphery; in the time that foreign matter or operator's health is strayed into the working zone of the AOI detection facility of working; the safe light curtain that optical transmitting set and optical receiver self check form can detect that this is strayed into and operates and AOI detection facility is quit work, thereby effectively avoid the generation of personal injury and the damage of AOI detection facility.
But; existing optical transmitting set and optical receiver are all made up of multiple infrared transmitting tubes or infrared receiving tube; when single bundle infrared emitting; control system receives only the signal of an infrared receiving tube corresponding with this infrared transmitting tube; and then carry out transmitting and the reception of a pair of infrared transmitting tube and infrared receiving tube below; just form the infrared protection light curtain of the parallel infrared beam composition of a lot of, had how much to infrared transmitting tube and infrared receiving tube, just formed how many line parallel light beams.If the region area of monitoring is large, must cause the light curtain equipment of needs many, the volume that the equipment that takies is limited, and increased the cost of production of equipment, electric energy expends also many simultaneously.
Model utility content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, provides a kind of safety protection range large, the light curtain protective gear for AOI detection facility that reliability is high.
The purpose of this utility model is achieved through the following technical solutions:
For the light curtain protective gear of AOI detection facility, comprising:
Launcher, described launcher sends unidirectional light beam;
The lens devices that is arranged on described launcher outside, described lens devices is launched described beam divergence;
Reflecting wall, the front side that is arranged on AOI detection facility is parallel with described launcher and symmetrical;
At least 2 reception units, are separately positioned on the left and right sides of launcher, and the light beam of dispersing transmitting is reflected back described reception unit through described reflecting wall.
Preferably, described launcher, reception unit are arranged on same PCB.
Concrete, also comprising a master controller and an alarm, described launcher, reception unit and alarm are all connected with master controller.
As a kind of improvement of the present utility model, the minute surface of described reflecting wall is spliced to form planar mirror by multiple minute surfaces.
Concrete, described lens devices comprises a shade, and described shade is provided with concavees lens, and described concavees lens and launcher are just to arranging.
The utility model has the following advantages and beneficial effect compared to existing technology:
The beam divergence transmitting that the utility model scioptics device sends launcher is reflected back described reception unit through reflecting wall; thereby the light beam that raising launcher sends is through the scope in region; greatly improve safety protection range large; testing precision is high; can reduce again the input of launcher simultaneously; reduce light curtain equipment cost, take equipment volume little.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but mode of execution of the present utility model is not limited to this.
Embodiment
As shown in Figure 1, this enforcement provides a kind of light curtain protective gear for AOI detection facility, comprising:
Launcher 1, described launcher 1 sends unidirectional light beam;
Be arranged on the lens devices 2 in described launcher 1 outside, described lens devices 2 is launched described beam divergence;
Reflecting wall 3, the front side that is arranged on AOI detection facility is parallel and symmetrical with described launcher 1;
At least 2 reception units 4, are separately positioned on the left and right sides of launcher 1, and the light beam of dispersing transmitting is reflected back described reception unit 4 through described reflecting wall 3.
Described launcher 1, reception unit 4 are arranged on same PCB.It is upper that launcher, reception unit are integrated in same PCB by said structure, makes light curtain protective gear volume little, and save cost.
Also comprise a master controller 5 and an alarm 6, described launcher 1, reception unit 4 and alarm 6 are all connected with master controller 5.On described master controller, connect an alarm, in the time of region before foreign matter or human body enter into AOI detection facility, all can be detected and send in time warning by alarm.
The minute surface of described reflecting wall is spliced to form planar mirror by multiple minute surfaces.By said structure, make it have very high reflectivity to light beam.
Concrete, described lens devices 2 comprises a shade 201, and described shade is provided with concavees lens 202, and described concavees lens 202 and launcher 1 are just to arranging.
Above-described embodiment is preferably mode of execution of the utility model; but mode of execution of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitutes, combination, simplify; all should be equivalent substitute mode, within being included in protection domain of the present utility model.
