Abstract
The invention relates to a car door lock catch component detection system which is characterized by comprising an automatic conveyor belt, a camera, an image processor and an automatic alarm device. Car door lock catches to be detected are arranged on the automatic conveyor belt. The camera is connected with the image processor. A lens of the camera is arranged towards the car door lock catches. The automatic alarm device is connected with the image processor. The camera is used for collecting images of the car door lock catches passing through the automatic conveyor belt, and sending the images to the image processor. The image processor is used for comparing the images of the car door lock catches with preset images of standard car door lock catches after the image processor receives the images of the car door lock catches. If the image difference is smaller than a threshold value, the car door lock catches are detected to be qualified, and if the image difference is larger than the threshold value, the car door lock catches are detected to be unqualified. The image processor can send out a control signal to the automatic alarm device, and the automatic alarm device sends out an alarm signal. Compared with the prior art, the car door lock catch component detection system has the advantages of being high in detection accuracy.
Description
Technical field
The present invention relates to a kind of auto parts and components detection system, especially relate to a kind of vehicle door bonnet lock component detection system.
Background technology
Vehicle door bonnet lock is to be formed by snap close rod and the riveted joint of snap close base plate, is vital and rivet this procedure, and this operation directly influences the quality of vehicle door bonnet lock.Therefore, need carry out repetition test and demonstration, formulate a reasonably riveted joint diameter.In traditional production process, all vehicle door bonnet locks of riveting are many must be with vernier caliper to the riveted joint diameter measurement, just can carry out next process after reaching requirement.Whether vehicle door bonnet lock riveted joint intact, is mostly to control by manual detection, has not only spent very big human and material resources, and has required personnel to guarantee that the such measure of product quality also is a kind of interim measure, can not be absolute stop to rivet defective.But vehicle door bonnet lock is again the safety component on the automobile, must guarantee that 100% is qualified, also means some error to occur, and will relate to vehicle and safety of persons once an error occurs, consequence is very serious.
Summary of the invention
Purpose of the present invention is exactly to provide a kind of accuracy in detection high vehicle door bonnet lock component detection system for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of vehicle door bonnet lock component detection system, comprise automatic conveying belt, camera, image processor and autoalarm, vehicle door bonnet lock to be detected is arranged on the automatic conveying belt, described camera connects image processor, the lens direction of camera is towards the vehicle door bonnet lock setting, and described autoalarm connects image processor;
Camera collection is by the image of the vehicle door bonnet lock of automatic conveying belt, and this image is sent to image processor, after image processor receives this image, itself and default standard vehicle door bonnet lock image are compared, if image difference is less than threshold value, it is qualified then to detect; If it is defective that image difference above threshold value, then detects, image processor sends and controls signal to autoalarm, sends alerting signal by autoalarm.
Described automatic conveying belt comprises for delivery of the pan feeding conveying belt of vehicle door bonnet lock to be detected and for delivery of the discharging conveying belt that detects qualified vehicle door bonnet lock, described camera be arranged on the pan feeding conveying belt directly over.
Described pan feeding conveying belt is vertical mutually with the discharging conveying belt.
Vehicle door bonnet lock to be detected is provided with two riveted holes, described camera is by the image of taking vehicle door bonnet lock directly over the pan feeding conveying belt, and this image is sent to image processor, image processor obtains the diameter of two riveted holes according to the image calculation of obtaining, and compare with default diameter data, if data difference is less than threshold value, it is qualified then to detect; If it is defective that data difference above threshold value, then detects, image processor sends and controls signal to autoalarm, sends alerting signal by autoalarm.
Described camera is the CCD camera.
Compared with prior art, the present invention obtains the image of vehicle door bonnet lock by camera, image processor directly carries out parameter relatively with the image of presetting, can not introduce the sum of errors mistake that is caused by manually-operated, can realize detecting accurately, the vehicle door bonnet lock that guarantees to enter subsequent processing fully is 100% qualified parts, and can enhance productivity greatly and the punctual rate of shipment.
Description of drawings
Fig. 1 is structured flowchart of the present invention;
Fig. 2 is on-the-spot arrangenent diagram of the present invention.
Embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment
As depicted in figs. 1 and 2, a kind of vehicle door bonnet lock component detection system comprises automatic conveying belt 4, camera 1, image processor 2 and autoalarm 3.Wherein, automatic conveying belt comprises mutual vertically disposed pan feeding conveying belt 42 and discharging conveying belt 41, pan feeding conveying belt 42 is used for for delivery of vehicle door bonnet lock to be detected, discharging conveying belt 41 is for delivery of detecting qualified vehicle door bonnet lock, camera 1 adopts the CCD camera, be arranged on pan feeding conveying belt 42 directly over.
Vehicle door bonnet lock to be detected is arranged on the automatic conveying belt 4, and by 42 inputs of pan feeding conveying belt, the lens direction of camera 1 is towards the vehicle door bonnet lock setting.Because vehicle door bonnet lock to be detected is provided with two riveted holes, camera 1 is by the image of taking vehicle door bonnet lock directly over the pan feeding conveying belt 42, and this image is sent to image processor 2, image processor 2 obtains the diameter of two riveted holes according to the image calculation of obtaining, and compare with default diameter data, if data difference is less than threshold value, it is qualified then to detect, and is delivered to the specification product zone by discharging conveying belt 41; If it is defective that data difference above threshold value, then detects, image processor 2 sends and controls signal to autoalarm 3, sends alerting signal by autoalarm 3.
Because the present invention obtains the image of vehicle door bonnet lock by camera, image processor directly carries out parameter relatively with the image of presetting, can not introduce the sum of errors mistake that is caused by manually-operated, can realize detecting accurately, the vehicle door bonnet lock that guarantees to enter subsequent processing fully is 100% qualified parts, and can enhance productivity greatly and the punctual rate of shipment.
