Embodiment Construction

[0013] Depend on figure 1 It can be seen that the strip steel hole online detection device of the present invention is mainly composed of a code disc 3, a laser emitting assembly 4, a laser receiving assembly 5, a counter 6, a single-chip controller group 7, an acousto-optic alarm 8 and a display 9. The single-chip controller group 7 has a single-chip and a main single-chip. The laser emitting assembly 4 and the laser receiving assembly 5 are correspondingly arranged on both sides of the vertical strip steel 1 at the looper exit, the display 9 and the sound and light alarm 8 are arranged in the operating room, and the code disc 3 is installed on the coiler 2 synchronously with the strip steel. On the roller shaft, the code disc 3 is connected to the single-chip controller group 7 through the counter 6, and at the same time, the single-chip controller group 7 is also connected to the laser receiving component 5, the sound and light alarm 8 and the display 9 respectively.

Abstract

The invention provides a strip steel hole online detection method. The detection apparatus comprises a laser emitting assembly, a laser receiving assembly, a single-chip computer controller group, a display device, an audible and visual alarm device, a code disk and a counter, wherein the laser receiving assembly is used to perform light transmittance determination, whether the edge and the middle of a strip steel have a hole is logically determined through a single-chip computer, a signal is transmitted to a main single-chip computer, the main single-chip computer performs coil changing and calculates and outputs the current position and hole information, audible and visual alarm and information displaying are performed, and an operator confirms and marks the hole information of the online steel coil according to the obtained information. With the strip steel hole online detection method of the present invention, the online real-time detection on the strip steel irregular hole defect is achieved, and the defect position information is accurately output, such that the hole is cut in the subsequent re-coiling step so as to substantially improve the strip steel quality, avoid the producing of the strip steel having the hole defect, and reduce the harm to the user.

Description

technical field [0001] The invention belongs to the technical field of steel rolling technology, and in particular relates to an online detection method for hole defects in cold-rolled strip steel. Background technique [0002] In the fields of aluminum strip, papermaking, and especially steel, the products run at high speed. Due to various reasons, there are irregular holes on the strip steel, which directly affects whether the product is qualified or not. The damage of holes to product quality is huge, not only will lead to product scrapping, but once it leaves the factory, it will also bring a lot of harm to users. Therefore, holes are effectively checked out and accurately removed to avoid holes affecting the final product. User usage is very unnecessary. Contents of the invention [0003] The invention provides a laser-based on-line detection method for holes in strip steel, the purpose of which is to realize on-line accurate position inspection of irregular hole def...
