Abstract
The present invention relates to a kind of car door lock catch component detection system, it is characterized in that, including automatic conveying belt, photographic head, image processor and autoalarm, vehicle door bonnet lock to be detected is arranged in automatic conveying belt, described photographic head connects image processor, the lens direction of photographic head is arranged towards vehicle door bonnet lock, and described autoalarm connects image processor；Camera collection is by the image of the vehicle door bonnet lock of automatic conveying belt, and sends this image to image processor, after image processor receives this image, it is compared with the standard vehicle door latch image preset, if image difference is less than threshold value, then it is qualified to detect；If image difference exceedes threshold value, then detecting defective, image processor sends and controls signal to autoalarm, autoalarm send alarm signal.Compared with prior art, the present invention has the advantage that accuracy in detection is high.
Description
Technical field
The present invention relates to a kind of auto parts and components detection system, especially relate to a kind of car door lock catch component detection system.
Background technology
Vehicle door bonnet lock be by snap close rod and snap close base plate riveted joint form, and rivet this procedure it is critical that, this operation directly affects the quality of vehicle door bonnet lock.Accordingly, it would be desirable to carry out repetition test and demonstration, formulate a rational riveted joint diameter.In traditional production process, vehicle door bonnet lock that all riveted joints are good is many with slide gauge to riveted joint diameter measurement, just must can carry out next process after reaching requirement.Whether vehicle door bonnet lock riveted joint is intact, is mostly that manually detection controls, and not only takes very big human and material resources, and requires that personnel are to ensure that the such measure of product quality is also a kind of interim measure, it is impossible to absolute stops riveted joint defect.But vehicle door bonnet lock is again the safety component on automobile, it is necessary to assure 100% is qualified, also implying that some error occur, once occurring that an error will relate to the safety of vehicle and personnel, consequence is very serious.
Summary of the invention
Defect that the purpose of the present invention is contemplated to overcome above-mentioned prior art to exist and the car door lock catch component detection system that a kind of accuracy in detection is high is provided.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of car door lock catch component detection system, including automatic conveying belt, photographic head, image processor and autoalarm, vehicle door bonnet lock to be detected is arranged in automatic conveying belt, described photographic head connects image processor, the lens direction of photographic head is arranged towards vehicle door bonnet lock, and described autoalarm connects image processor；
Camera collection is by the image of the vehicle door bonnet lock of automatic conveying belt, and sends this image to image processor, after image processor receives this image, it is compared with the standard vehicle door latch image preset, if image difference is less than threshold value, then it is qualified to detect；If image difference exceedes threshold value, then detecting defective, image processor sends and controls signal to autoalarm, autoalarm send alarm signal.
Described automatic conveying belt includes for carrying the pan feeding conveyer belt of vehicle door bonnet lock to be detected and the discharging conveyor belts of the vehicle door bonnet lock for carrying detection qualified, and described photographic head is arranged on the surface of pan feeding conveyer belt.
Described pan feeding conveyer belt and discharging conveyor belts are mutually perpendicular to.
Vehicle door bonnet lock to be detected is provided with two riveted holes, described photographic head is by the image shooting vehicle door bonnet lock directly over pan feeding conveyer belt, and this image is sent to image processor, image processor calculates the diameter obtaining two riveted holes according to the image obtained, and contrast with default diameter data, if data difference is less than threshold value, then it is qualified to detect；If data difference exceedes threshold value, then detecting defective, image processor sends and controls signal to autoalarm, autoalarm send alarm signal.
Described photographic head is CCD camera.
Compared with prior art, the present invention obtains the image of vehicle door bonnet lock by photographic head, image processor directly carries out parameter with the image preset and compares, the error and mistake that are caused by manual operation will not be introduced, can realize detecting accurately, the acceptable parts that vehicle door bonnet lock be 100% that enter subsequent processing is completely secured, and production efficiency and the punctual rate of shipment can be greatly improved.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of the present invention；
Fig. 2 is the site layout project figure of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As depicted in figs. 1 and 2, a kind of car door lock catch component detection system, including automatic conveying belt 4, photographic head 1, image processor 2 and autoalarm 3.Wherein, automatic conveying belt includes the pan feeding conveyer belt 42 and the discharging conveyor belts 41 that are arranged in a mutually vertical manner, pan feeding conveyer belt 42 is for for carrying vehicle door bonnet lock to be detected, discharging conveyor belts 41 detects qualified vehicle door bonnet lock for carrying, photographic head 1 adopts CCD camera, is arranged on the surface of pan feeding conveyer belt 42.
Vehicle door bonnet lock to be detected is arranged in automatic conveying belt 4, pan feeding conveyer belt 42 input, and the lens direction of photographic head 1 is arranged towards vehicle door bonnet lock.Owing to vehicle door bonnet lock to be detected is provided with two riveted holes, photographic head 1 is by the image shooting vehicle door bonnet lock directly over pan feeding conveyer belt 42, and this image is sent to image processor 2, image processor 2 calculates the diameter obtaining two riveted holes according to the image obtained, and contrast with default diameter data, if data difference is less than threshold value, then it is qualified to detect, discharging conveyor belts 41 deliver to qualified products region；If data difference exceedes threshold value, then detecting defective, image processor 2 sends and controls signal to autoalarm 3, autoalarm 3 send alarm signal.
Owing to the present invention is by the image of photographic head acquisition vehicle door bonnet lock, image processor directly carries out parameter with the image preset and compares, the error and mistake that are caused by manual operation will not be introduced, can realize detecting accurately, the acceptable parts that vehicle door bonnet lock be 100% that enter subsequent processing is completely secured, and production efficiency and the punctual rate of shipment can be greatly improved.
