Abstract
The utility model relates to an LED inspecting device. The LED inspecting device comprises a conveying belt used for delivering LEDs, and an image identifying component arranged above the LED conveying belt, wherein the image identifying component comprises a first camera used for identifying an foreign object on the surface of the LED, a second camera used for identifying a disqualified part in the interior of the LED, a mark pen and a control unit; and the first camera, the second camera and the mark pen are sequentially arranged above the conveying belt. In virtue of the scanning function of the ultraviolet ray cameras, the disqualified part on the surface of and in interior of the LED is screened, marked and coated for distinguishing, so that the purpose of automatic inspection is achieved; the disqualified part on the surface of and in interior of the LED is screened effectively, thereby avoiding missed inspection caused by factitious errors, ensuring the product quality, improving the production efficiency and reducing manufacturing cost at the same time.
Description
Technical field
The utility model relates to LED and makes the field, particularly relates to a kind of testing fixture of LED outward appearance.
Background technology
LED (Light Emitting Diode, light emitting diode) is a kind of semiconductor solid luminescence device, its principle is to utilize the solid semiconductor chip as luminescent material, and when the chip two ends feed forward voltage, the charge carrier in the semiconductor takes place compoundly to cause photo emissions and produce light.Because characteristics such as the LED operating voltage is low, power consumption is little, the high and low heat of luminescence efficiency, long service life, environmental protection are widely used in technical fields such as illumination, display lamp.
LED makes and uses five big starting material, comprises nead frame (LeadFrame), chip (Chip), elargol, gold thread and epoxy resin.And in manufacturing process, some link can be stained with deficient manufacturing procedures such as glue just like foreign matter, solid brilliant, the empty weldering of nothing, wafer, at present these bad mainly by high-power microscope detect, personnel's mark or choose removes etc., and instrument is rejected bad, these people are taken place for the operation meeting has leakage phenomena because of the personnel ability is uneven, influence the quality of product.
Summary of the invention
The utility model provides a kind of LED testing fixture.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of LED testing fixture, comprise LED conveying conveying belt, be arranged on the image identification component of described LED conveying belt top, described image identification component comprises first camera that is used to discern the LED Superficial Foreign Body, is used to discern LED inner bad second camera, marker pen and control module, and described first camera, second camera, marker pen are successively set on described conveying belt top.
Preferably, described testing fixture also comprises the memory unit that is used to write down bad LED.
Preferably, described image identification component also comprises illuminace component.
Preferably, described first camera, second camera are ultraviolet camera.
In the processing procedure link, import by " LED testing fixture ",, will comprise LED surface and inner bad screening by ultraviolet camera scan function, and the mark differentiation of tinting, to reach the purpose of self-verifying.
Because technique scheme utilization, the utility model compared with prior art has following advantage: the utility model can be effectively with bad the screening of LED surface and inside, avoided the omission that causes because of human error, guaranteed the quality of product; Simultaneously also improve production efficiency, reduced production cost.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Wherein: 1, conveying belt; 2, image identification component; 3, first camera; 4, second camera; 5, marker pen; 6, control module; 7, memory unit; 8, illuminace component.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
A kind of LED testing fixture as shown in Figure 1, comprise LED conveying conveying belt 1, be arranged on LED conveying belt top image identification component 2, be used to write down the memory unit 7 of bad LED.Wherein: image identification component 2 comprises first camera 3 that is used to discern the LED Superficial Foreign Body, be used to discern inner bad second camera 4, marker pen 5, illuminace component and control module 6, the first cameras 3, second camera 4, the marker pen 5 of LED is successively set on conveying belt 1 top.In the present embodiment, first camera 3, second camera 4 all adopt ultraviolet camera.
Below the concrete method of operating of present embodiment down of setting forth:
LED is introduced into first camera 3 by the transmission of carrying 1 band its surface is scanned, and determines whether its surface exists foreign matter, and the result after the scanning is sent to control module 6; LED enters second camera 4 its inside is scanned, and determines whether its inside exists foreign matter or bad, and the result after the scanning is sent to control module 6; Result after 6 pairs of twice scannings of control module judges, and sends instruction to marker pen 5, and when LED surface or internal abnormality, 5 couples of these LED of marker pen carry out mark; Handle being coated with underlined LED at last, avoided artificial omission and cause the outflow of defective products.
In addition, various bad storage that LED appears in the memory unit 7 in this device is so that monitor the quality of LED.
The foregoing description only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with this technology can understand content of the present utility model and enforcement according to this, can not limit protection domain of the present utility model with this.All equivalences of being done according to the utility model spirit change or modify, and all should be encompassed within the protection domain of the present utility model.
