Detailed description of the invention
For understanding content of the present invention further, by reference to the accompanying drawings and embodiment the present invention is described in detail.
embodiment 1
Composition graphs 1 and Fig. 2, a kind of assembly line photo comparison checkout gear of the present embodiment, comprise liquid crystal display 1 and integrated box 2, it also comprises checkout gear 3, liquid crystal display 1 is connected by screen transmission line with integrated box 2, integrated box 2 is connected by signal transmssion line with checkout gear 3, and integrated box 2 is also connected with assembly line controller.
Checkout gear 3 is covered with dust-proof, water-proof cover, prevents the cloth such as the water smoke in workshop, dust on checkout gear 3, affect the Detection results of checkout gear 3, easily make checkout gear 3 damage simultaneously, thus the equipment cost adding testing process drops into.
Integrated box 2 is provided with buzzer 21, USB interface 22, when judgement assembling product is wrong, integrated box 2 sends a signal to assembly line body controller and stops that this product stream is to next station, and the buzzer 21 be provided with by integrated box 2 sounds the alarm, assembling workman is reminded to note assembling wrong or neglected loading part, under storing in whole testing flow process all testing products photo and can displaying time and bad test point, for searching and backing up by USB interface 22, use for the later stage.
Checkout gear 3 comprises first camera 31, first light source 32, second camera 33, secondary light source 34, column 35 and universal joint 36, column 35 has four, and front and back be arranged in parallel in a straight line, first camera 31, first light source 32, second camera 33, secondary light source 34 are all connected with four root posts 35 respectively by universal joint 36, and first camera 31, first light source 32, second camera 33, secondary light source 34 are all by angle that universal joint 36 adjusts the height needed for it or adjusts required for it.
First camera 31 and second camera 33 are infrared camera, secondary light source 34 and the first light source 32 are infrared light sources, first camera 31 and second camera 33 are infrared camera in the present embodiment, secondary light source 34 and the first light source 32 are infrared light sources, adopt infrared light sources and infrared camera with the use of, can reduce as far as possible around light source to the accuracy of detection of test point, thus improve photo comparison detect quality.
Secondary light source 34 is greater than the height of second camera 33 apart from ground apart from the height on ground, line and the horizontal angle of second camera 33 and product to be measured are 30 ° ~ 60 °, second camera 33 is equal with horizontal angle with the line of product to be measured with secondary light source 34 with horizontal angle with the line of product to be measured, product to be detected is testing product whether assembly defect or neglected loading part under the effect of secondary light source 34 and second camera 33, if cooperatively interacting of secondary light source 34 and second camera 33 can not testing product whether assembly defect or can not find the position of neglected loading part all sidedly all sidedly, bring immeasurable loss then will to the production in later stage, therefore secondary light source 34 and second camera 33 good fit is the core of whole checkout gear 3, through a large amount of practice processes, when the cooperation of secondary light source 34 and second camera 33 possesses following factor, can be effectively, testing product in high quality: 1, secondary light source 34 is greater than the height of second camera 33 apart from ground apart from the height on ground, 2, the line of second camera 33 and product to be measured and horizontal angle are 30 ° ~ 60 °, 3, second camera 33 is equal with horizontal angle with the line of product to be measured with secondary light source 34 with horizontal angle with the line of product to be measured.To be combined with each other setting by above-mentioned three, secondary light source 34 can be avoided effectively, and the impact of ambient light is omnibearing when being irradiated to the measuring point to be checked of product to be detected, second camera 33 same angle can take the test point of product to be detected clearly, then contrast with standard photographs, thus the testing product avoiding testing product assembly defect or neglected loading part enters next streamline, finally avoid the impact of substandard product on whole production line, if the position of second camera 33 and secondary light source 34 reasonably can not be arranged in this testing process, measuring point to be checked will be made not photographed or qualified product is detected as defective, huge trouble is brought to production in capital, therefore second camera 33 and secondary light source 34 is reasonable, effective layout to be vitally also absolutely necessary.
The present embodiment assembly line photo comparison checkout gear before use, first carry out checkout gear 3 to focus, first light source 32 and first camera 31 are aimed at product bar code position to be detected, ensure that first camera 31 accurately can collect the information of bar code clearly, then secondary light source 34 and second camera 33 are aimed at the position that product will detect, make second camera 33 equal with horizontal angle with the line of product to be measured with secondary light source 34 with horizontal angle with the line of product to be measured by the universal joint 36 on adjustment column 35, ensure that second camera 33 accurately can collect the image detecting position clearly simultaneously.After last station completes the assembling of product to be detected, product to be detected reaches detection station along streamline, the first light source 32 in checkout gear 3 will send infrared light, first camera 31 can take the bar code that product to be detected identifies simultaneously, and transfer data to integrated box 2, contrast with the normal pictures of the product to be detected set in integrated box 2 before, when bar code product to be detected identified if take is consistent with the picture comparing result that will detect set in integrated box 2, then second camera 33 and secondary light source 34 carry out work (if inconsistent, judge this product to be detected without the need to detect, second camera 33 and secondary light source 34 will not work, release signal releases this product to assembly line body controller simultaneously), photo second camera 33 being gathered Product checking installation site to be detected is transferred to integrated box 2 again, contrast with the normal pictures arranged in integrated box 2 before, consistent if (namely judging that product is certified products), integrated box 2 release signals are to assembly line body controller, release this product.If inconsistent, judge that this assembling product is wrong, and send a signal to assembly line body controller and stop that this product stream is to next station, and the buzzer 21 be provided with by integrated box 2 sounds the alarm.Under storing in this testing flow process all testing products photo and can displaying time and bad test point, for searching and backing up by USB interface 22, use for the later stage.
Schematically above be described the present invention and embodiment thereof, this description does not have restricted, and also just one of the embodiments of the present invention shown in accompanying drawing, actual structure is not limited thereto.So, if those of ordinary skill in the art enlightens by it, when not departing from the invention aim, designing the frame mode similar to this technical scheme and embodiment without creationary, all should protection scope of the present invention be belonged to.
