The imaging device is simple in structure, convenient for use, full-automatic in control and high in detection precision, reduces the omission factor and improves the end product quality of the steel strip.
Description
Technical field
The utility model relates to imager, more particularly, relates to a kind of band steel sidepiece imaging device.
Background technology
On the hot rolling tandem mill production line of iron and steel enterprise; Usually all will batch the zone strip surface quality and coil of strip Forming Quality are detected; Promptly before batching, strip surface quality is carried out online detection, after batching, the part coil of strip is carried out the uncoiling inspection and confirm and sampling.The former utilizes machine vision and image model recognition technology that the blemish of hot-strip is carried out online detection, and the latter carries out off-line inspection and sampling through quality examination unit indirect labor.Yet,, generally can only check at present through artificial visually examine's mode for band steel both sides defective.But, because the scene is under the hyperthermia radiation environment, can't close-ups, cause visual inspection efficient low and loss is very high.
In addition, the strip surface quality checkout gear of prior art can't be applicable to that also band steel sidepiece detects.This be because: at first, be that the detection position is different, surface quality detection device generally is installed between finishing mill and the coiling machine, be continuous imaging to be carried out on band steel and surface thereof detect, and the detection position of band steel sidepiece defective is on the two sides of band steel; Secondly, be that detected object is different, the surface quality detection system is used to detect the steel plate upper and lower surfaces of uncoiling state, if be used for detecting the hot-strip both sides that have been shaped, exists the problem that the equipment configuration is not complementary; The 3rd, be that to detect the kind of defective different, surface detection apparatus mainly detects blemish such as impression, iron sheet, scuffing, slag inclusion, is defectives such as limit damage, flanging, folding, burr, sawtooth split and band steel sidepiece mainly detects.Therefore, utilizing existing strip surface quality checkout gear is effectively to detect the characteristic that comprises this type defective, more can't realize the accurate detection to the end defective.
The utility model content
To the above-mentioned shortcoming that exists in the prior art, the purpose of the utility model provides a kind of band steel sidepiece imaging device, is applicable to that the imaging of band steel sidepiece defective detects.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
This band steel sidepiece imaging device comprises casing, photoelectric sensor, flash lamp, camera and grating; Offer successively on the front face of casing and detect hole, illumination holes and imaging hole; Photoelectric sensor, flash lamp, camera all are located in the casing and are laid respectively at and detect the corresponding position of hole, illumination holes and imaging hole; Grating is located at the casing outside, and corresponding with photoelectric sensor.
Be provided with fixed support and traversing carriage in the described casing, described photoelectric sensor, flash lamp are located on the fixed support respectively; Described camera is located on the traversing carriage.
This imaging device also comprises a protective cover, covers at the outside of casing front face, also has and detect corresponding three holes of hole, illumination holes and imaging hole on the protective cover.
Also have cooling vent on the back plate face of described casing.
In technique scheme; The band steel sidepiece imaging device of the utility model comprises casing, is located at photoelectric sensor, flash lamp, the camera in the casing and is located at the outer grating of casing; Through imaging device and grating are located at band both sides, steel rider road respectively; And whether photoelectric sensor blocked as taking switch by the band steel with the grating signal that receives, the band steel sidepiece through imaging device is carried out automated imaging, to gather the correlated characteristic data of being with steel sidepiece defective.This imaging device has simple in structure, easy to use, full-automatic control, and accuracy of detection is high, has reduced loss, has improved band steel end product quality.
Description of drawings
Fig. 1 is the structure and the user mode sketch map of the band steel sidepiece imaging device of the utility model.
The specific embodiment
Further specify the technical scheme of the utility model below in conjunction with accompanying drawing and embodiment.
See also shown in Figure 1ly, the band steel sidepiece imaging device 10 of the utility model comprises casing 11, photoelectric sensor 12, flash lamp 13, camera 14 and grating 15.On the front face of casing 11, offer successively and detect hole 111, illumination holes 112 and imaging hole 113, in casing 11, also be provided with fixed support 16 and traversing carriage 17.And photoelectric sensor 12, flash lamp 13, camera 14 all are located in the casing 11 and lay respectively at and detect hole 111, illumination holes 112 and imaging hole 113 corresponding positions.Wherein, photoelectric sensor 12, flash lamp 13 are located at respectively on the fixed support 16, and keep the fixed position; And camera 14 is located on the traversing carriage 17; Can move forward and backward with traversing carriage 17, thereby can adjust the distance between camera 14 and band steel 1 sidepiece, to satisfy corresponding focal length requirement.Grating 15 is located at casing 11 outsides, and corresponding with photoelectric sensor 12, sends grating signal to photoelectric sensor 12.In addition; For each parts in the casing 11 receive on-the-spot temperatures involved; This imaging device 10 also comprises a protective cover 18; Cover at the outside of casing 11 front faces, on protective cover 18, also have and detect hole 111, illumination holes 112 and imaging hole 113 corresponding three holes 181, can effectively play the effect of thermal insulation protection through protective cover 18 each parts in the casing 11.And, on the back plate face of casing 11, also have a cooling vent 19, be used to connect air-conditioning, the temperature in the casing 11 is cooled off control.
The operation principle of this imaging device 10 is following:
The imaging device 10 of one cover the utility model is set in band steel rollgang 2 one sides of needs detection; Make photoelectric sensor 12, flash lamp 13, camera 14 be on the same horizontal line with the band steel 1 of process; And it is grating 15 is located at the opposite side of rollgang 2, and corresponding with photoelectric sensor 12.When grating 15 sent grating signal, photoelectric sensor 12 can receive, and this moment, imaging device 10 was not worked; And when the band steel 1 from rollgang 2 through out-of-date; In case grating 15 signals are blocked; Photoelectric sensor 12 fails to receive grating signal, controls flash lamp 13 immediately through computer and throws light on and control 14 pairs in camera band steel, 1 this sidepiece and take imaging continuously, and be carried out to picture through computer and show determining defects and the record that supplies band steel 1 sidepiece; Pass through until entire belt steel 1, photoelectric sensor 12 receives till grating 15 signals once more.Certainly, also can respectively establish a cover imaging device 10 simultaneously in rollgang 2 both sides, thereby can be carried out to picture to band steel 1 both sides respectively.
Those of ordinary skill in the art will be appreciated that; Above embodiment is used for explaining the utility model; And be not the qualification that is used as the utility model; As long as in the connotation scope of the utility model, all will drop in claims scope of the utility model variation, the modification of the above embodiment.
