Abstract
The utility model discloses a kind of low angle luminance adjustable light sources, it is characterized by comprising the LED light sources that two are symmetricly set on CCD camera assembly two sides, LED light source is connected on slide unit together with CCD camera assembly, slide unit is along sliding rail linear movement, LED light source is electrically connected with controller, controller can automatically adjust the brightness of LED light source, by the LED light source of low angle, so that detection device can more capture apparent unwanted visual characteristic.
Description
Technical field
The utility model belongs to defect detection engineering device technique field, concretely relates to a kind of low angle brightness tunable optical
Source.
Background technique
For warp knitting machine fabric defect detection device, under normal circumstances, LED backlight irradiation can reach good imaging
Quality and apparent unwanted visual characteristic, but under special circumstances, certain cloth types, texture cannot obtain in the case of backlight bright
Aobvious unwanted visual characteristic.
Summary of the invention
The purpose of the utility model is to provide a kind of low angle luminance adjustable light sources to be made by the LED light source of low angle
Apparent unwanted visual characteristic can more be captured by obtaining detection device.
In order to solve the above technical problems, purpose of the utility model is realized as follows:
A kind of low angle luminance adjustable light source, it is characterised in that: be symmetricly set on CCD camera assembly two sides including two
LED light source, LED light source are connected on slide unit together with CCD camera assembly, and slide unit is along sliding rail linear movement, LED light source electrical connection
There is controller, controller can automatically adjust the brightness of LED light source.
Preferred embodiment on the basis of above scheme and as above scheme: the LED light source is great power LED light
Source.
Preferred embodiment on the basis of above scheme and as above scheme: angle of the LED light source relative to cloth cover
Degree and position relative to CCD camera assembly are adjustable.
Compared with the prior art, the utility model has prominent and beneficial technical effects that: light source is fixed on slide unit, with
The movement of slide unit and move, light source direction of illumination and cloth cover are presented a smaller angle, system according to cloth cover actual conditions,
Image quality of the brightness of low angle light source to have guaranteed is automatically adjusted, symmetrically arranged light source can preferably increase light source and cover
The area of lid increases the field range of CCD camera assembly, that is to say, that improves the recall rate and detection efficiency of defect detection.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
Specific embodiment
To keep the purposes, technical schemes and advantages of the application clearer, below in conjunction with the attached drawing in embodiment, to reality
The technical solution applied in example is clearly and completely described, it is clear that described embodiment is only that the application a part is implemented
Example, rather than whole embodiments.Based on the embodiment provided, those of ordinary skill in the art are not before making creative work
Every other embodiment obtained is put, shall fall in the protection scope of this application.
In the description of the present application, it is to be understood that the orientation or positional relationship of the instructions such as term " on ", "lower" is base
In orientation or positional relationship shown in the drawings, it is merely for convenience of description the application and simplifies description, rather than indication or suggestion
Signified device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as to this
The limitation of application.
A kind of low angle luminance adjustable light source is symmetricly set on the LED light source 1 of 2 two sides of CCD camera assembly including two,
LED light source 1 and CCD camera assembly 2 are connected in together on slide unit 4, and slide unit 4 is electrically connected with along 5 linear movement of sliding rail, LED light source 1
Controller, controller can automatically adjust the brightness of LED light source 1.
Preferably, LED light source 1 is high-power LED light source.
Position of the LED light source 1 relative to the angle of fabric 3 and relative to CCD camera assembly 2 is adjustable.
Angular adjustment is realized by articulated section 11 and is adjusted, and the fastening screw of articulated section 11 is unscrewed, and adjusts the angle of LED light source 1
Degree, then screws the fastening screw of articulated section 11.
Slide unit 4 is provided with sliding slot, and 1 pedestal of LED light source is provided with the sliding block 12 that can be slided in sliding slot, and sliding block 12 passes through top
Tight screw is held out against in sliding slot, and when adjusting position unscrews holds out against screw, then the position of adjusting slider 12 screws holds out against screw.
Controller can control the brightness of LED light source, while can also drive servo motor 6, and servo motor 6 passes through lead screw spiral shell
Female adjutant's power is transferred to slide unit 4, realizes the movement of slide unit 4.
Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this
It encloses, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by the protection of the utility model
Within the scope of.
