Abstract
The utility model relates to a large-area photoinduction device. The large-area photoinduction device comprises a photosensing device, an amplifier and a data display instrument, wherein the amplifier is connected with the photosensing device and the data display instrument respectively. Compared with the prior art, the utility model has the advantages that the device can perform large-area photoinduction detection, and can meet different check ranges and different measurement requirements through the increase and decrease and the position arrangement of photoinduction sensors according to applied concrete occasions; and the device can realize the high-speed high-accuracy measurement and discrimination of light intensity, and can display measurement results and set criteria through the data display instrument.
Description
Technical field
The utility model relates to a kind of induction installation, especially relates to a kind of large tracts of land Photoinduction device.
Background technology
At present a lot of industries all need some the mesomorphic product in parts, product, the manufacture process is carried out defects detection, such as the pore size of product, have or not etc.Present this inspection detects general by Manual Visual Inspection, and working strength is large, efficient is low.Adopt the inspection of industrial camera, the checkout facility price is higher, and the Limited eyeshot of industrial camera has determined detection and inconvenience to the large tracts of land object.
The photoinduction sensor that produces electrical output signal during light beam irradiates is well-known, industrial be widely used in object have or not detection etc.But single photoinduction ranges of sensors is too little, can't detect the large tracts of land object.
The utility model content
The purpose of this utility model is exactly to provide a kind of for the defective that overcomes above-mentioned prior art existence can carry out the large tracts of land Photoinduction device that large-area photoinduction detects.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of large tracts of land Photoinduction device, this device comprises photosensitive device, amplifier and digital wash, described amplifier is connected with photosensitive device and digital wash respectively.
Described photosensitive device comprises substrate, photoinduction sensor and transparent panel, and described photoinduction sensor is arranged in order and is installed on the substrate, is connected in parallel between each photoinduction sensor, and described transparent panel is located at the place ahead of the light-sensitive surface of photosensitive device.
Described transparent panel is the clear sheet of protection photoinduction sensor.
Described amplifier converts the electric signal process unit of voltage signal and filtering clutter to for the small photocurrent that the photoinduction sensor is sent.
Described digital wash detects the display device of numerical value for showing voltage signal.
Compared with prior art, the utlity model has following advantage:
1, single photoinduction sensor can only carry out the detection that object has or not, and the present invention then can carry out large-area photoinduction and detect.
2, can come corresponding different examination scope and different measurement needs by increase and decrease, the positional alignment of photoinduction sensor according to the concrete occasion of using.
3, this device can be realized the high-speed, high precision measurement of light intensity and differentiate, and can come the display measurement result by digital wash, criterion is set.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the main TV structure synoptic diagram of photosensitive device;
Fig. 3 is the structural representation of looking up of photosensitive device.
Among the figure, 1 is that photosensitive device, 2 is that amplifier, 3 is that digital wash, 4 is that substrate, 5 is that photoinduction sensor, 6 is transparent panel.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of large tracts of land Photoinduction device, its structure as Figure 1-3, this device comprises that photosensitive device 1, amplifier 2 and digital wash 3 consist of, amplifier 2 is connected with photosensitive device 1 and digital wash 3 respectively.According to required photoinduction area and shape, the photoinduction sensor 5 of some is arranged in order in certain sequence is installed on the substrate 4, each photoinduction sensor 5 is connected in parallel.In the place ahead of light-sensitive surface a transparent panel 6 is installed, in order to scattered light and protect photoinduction sensor 5.Amplifier 2 converts the small photocurrent that photoinduction sensor 5 sends to voltage signal, filtering clutter.Final voltage signal detects numerical value and shows at digital wash 3.Therefore this device not only can in industrial defects detection for part, product, also can directly be used in and be used for detecting intensity of illumination on some equipment and the instrument.
When being used for industrial defects detection, a light source is placed on opposite at photosensitive device 1, tested part, product can cover light source through time between photosensitive device 1 and the light source, but when part exists defective or product ad-hoc location to have the hole, the light of light source is understood some and is shone on the photosensitive device 1, thereby detects part defect or obtain the information in hole on the product.
