Specific embodiment:
In order to deepen the understanding of the present invention, the present embodiment is described in detail with reference to the accompanying drawing.
Embodiment 1: referring to figures 1-3, a kind of hot rolling surface quality detecting system roller-way panel turnover device, the panel turnover device Including detector and transition plates component, the detector includes receiving instrument 3 and transmitter 12, and the transition plates component includes left axle Folded seat 1, transition plates 2,4- ray, right bearing 6, crank 7, drive cylinder 8, oil cylinder seat 11, dormant bolt 20 and square shaft 22 are held, The left shaft holder 1 and right bearing 6 are separately positioned on the two sides of transition plates, and the both ends of the square shaft 22 are that circular shaft axis is stretched, one end Circular shaft axis is stretched installs left shaft holder 1 above, and other end axis is stretched, and installs right bearing 6, crank 7, the oil cylinder is mounted on oil cylinder On seat, the oil cylinder is connect by plug with crank 7, and magnetic scale 9 is provided in the drive cylinder 8, is arranged on the receiving instrument 3 There is adjusting rod 5, the transition plates 2 is provided with inclined-plane 21, and the inclination angle on the inclined-plane 21 is 10 °~30 °.Its specific value and incline The depth at angle and the thickness of strip are related, and thickness is thinner, and angle is smaller;Magnetic scale lead 10 is had in the drive cylinder 8, will be drawn 10 access control system of line.By in set-up of control system program.When ensuring that only the rotation of transition plates 2 is more than 75 °, ability Acquire strip lower surface picture.To avoid interference of the transition plates to detector, and prevent steel scrap.
By adjusting adjusting rod 5, so that it is 2 millimeters -20 millimeters that ray, which folds wide range,.Referring to Fig. 1, adjustment receiving instrument 3 Mounting height, so that it may adjust the superposition width 4 of two rays 23.Strip is thicker, and superposition width 4 is smaller, but minimum cannot Less than 2 millimeters, otherwise strip is thinner, and superposition width 4 is bigger, but maximum no more than 20 millimeters.During rolled band steel, By rotation adjusting lever 5, above-mentioned adjusting can be completed, plate pawl, plate pawl interval 15 and plate pawl width are provided in the transition plates 2 The sum of 16 is identical away from the sum of 18 as transmitter mirror as transmitter mirror wide 17.Plate pawl interval 15 is in transmitter mirror away from 18 (1/3~2/ 3) when, plate pawl length piece number 14 is between (1.5~2) of transmitter mirror wide 17, the effect of detection is best;The ray is folded wide Range is 8 millimeters -15 millimeters.Through the above technical solution, the surface quality detection of strip can be realized, and in best State avoids reporting by mistake, also avoids steel scrap.
Working principle and control mode: referring to figures 1-4, the plant design of Surface Quality Inspection System is: system is not joined With light switch, the logic control of roller-way turnover panel, camera switch, these control signals are by Basic automation control system (following letter Claim L1) it provides.Therefore need to complete the control Design of Signal of Surface Quality Inspection System using L1 existing resource.Needed for system Interface signal has: illumination and the starting of camera, shutdown signal, roller-way turn over plate control signal, the strip for controlling filming frequency Speed signal.
According to on-site actual situations, required I/O signal is all accessed into input and output cabinet.Increase 3 program modules newly in L1 (CONTROL_SIS, BOARD_CON, SPEED_SIS) is used for interface control program.In addition internal system is also required to be detected Control setting.
Control mode explanation, is detailed in Fig. 4:
(1) CONTROL_SIS: the signal for system illumination, camera switch controls.Design logic are as follows:
A) light switch controls: after when mm finishing mill unit end, rack stings steel, illumination comes into operation (need to preheat principle according to illumination in advance Design);After system outlet pyrometer power loss, illumination is closed.
B) camera switch controls: when strip passes through system entry, and entrance pyrometer and entrance HMD signal move at the same time, Camera comes into operation;When entrance HMD signal power loss, camera is closed.
(2) BOARD_CON: signal control and relative alarm for roller-way turnover panel are shown.Roller-way turnover panel using manually and Automatic both of which control;It selects to select long-range to automatically control, the design logic of automatic control mode by machine to manually control Are as follows:
When system outlet pyrometer and outlet HMD simultaneously operation, roller-way turnover panel is opened;When outlet pyrometer or outlet After the movement of HMD either signal, roller-way turnover panel is closed.
(3) SPEED_SIS: for controlling the strip speed signal acquisition of camera filming frequency.
(4) internal system detection control: by upper table start check bit install received for camera come into operation signal when;By following table Start check bit to install are as follows: upper table starts to detect position+upper following table camera beam offset (upper table camera beam is preceding).
The above logical program, without any exception, meets system items design requirement in debugging process.
It should be noted that above-described embodiment, is not intended to limit the scope of protection of the present invention, in above-mentioned technical proposal On the basis of made equivalents or substitution each fall within the range that the claims in the present invention are protected.
