Abstract
The utility model belongs to an on-line detecting device of steel plate holes. The on-line detecting device solves the problems that the prior art can only give an alarm when founding a hole without displaying the exact position of the hole, moreover the installation and manufacture of the stabilizing device of light source are very complex. The on-line detecting device has the following technical measures: The on-line detecting device of steel plate hole consists of a bracket 1, an ultraviolet source 2 connected with the bracket 1, a photoelectric receiver 3, a control cabinet 5 connected with the photoelectric receiver 3 by a signal wire 4, a photomask 6 connected with the photoelectric receiver 3, a light filter 7 arranged between the photoelectric receiver 3 and the ultraviolet source 2, a light barrier 8 mounted at the two sides of the photoelectric receiver 3, an automatic tracker 11 connected with the light barrier 8 and a servo motor 12 connected with the light barrier 8. The ultraviolet source 2 is connected with a ballast 10 by a lead 9. The photoelectric receiver 3 is a photomultiplier. With the advantages of convenient connection, low cost and easy implementation, the on-line detecting device can display the exact position of the hole directly, which is favorable for improving product quality.
Description
Technical field
The utility model relates to pick-up unit, specifically belongs to online steel plate cavity detection device.
Background technology
Thin plate because a variety of causes hole can occur once in a while in the operation of rolling, in order in time to find and to handle, is guaranteed the product quality of thin plate in process of production, must use modern checkout equipment.
Before this patent, what generally adopt is the hole instrument that U.S. Thermo Fischer Scient Inc. produces, its weak point is that this device discovery hole can only report to the police, the particular location that can not directly show hole, to could show the distance of hole by slave computer to starting point, can not in time obtain testing result in case slave computer breaks down, what the more stable assurance of light source is adopted is circuit board, its installation and make all complicated.
The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and the cavity detection device of a kind of particular location, light stability device that can directly show hole online steel plate simple in structure, easy to connect is provided.
Realize the technical measures of above-mentioned purpose:
Steel plate hole on-line measuring device, by support, be connected in ultraviolet source on the support, photelectric receiver, the switch board that is connected by signal wire with photelectric receiver, be connected in light shield on the photelectric receiver, be installed on the light filter between photelectric receiver and the ultraviolet source, the light barrier that is loaded on the photelectric receiver both sides, the autotracking unit that is connected with light barrier, the servomotor that is connected on the light barrier form, and connects ballast resistor by lead on its ultraviolet source; Photelectric receiver is a photomultiplier.
The utility model can directly show hole particular location, be beneficial to and improve the product quality of dispatching from the factory, and easy to connect, cost is low, as easy as rolling off a log enforcement.
Description of drawings
Fig. 1 is the structural representation of steel plate hole on-line measuring device
Embodiment
Be further described below in conjunction with accompanying drawing:
By support (1), be connected in the ultraviolet source (2) on the support (1), photelectric receiver (3), the switch board (5) that is connected by signal wire (4) with photelectric receiver (3), be connected in the light shield (6) on the photelectric receiver (3), be installed on the light filter (7) between photelectric receiver (3) and the ultraviolet source (2), be loaded on the light barrier (8) of photelectric receiver (3) both sides, the autotracking unit (11) that is connected with light barrier (8), be connected in the steel plate hole on-line measuring device that the servomotor (12) on the light barrier (8) is formed, can be in order to ensure any one the small hole on the coil of strip by omission, ultraviolet source (2) is selected four ultraviolet lamp tube assemblings for use, and the lampshade (6) that connection has ultraviolet reflecting power on four ultraviolet lamp tubes, no matter ultraviolet light from which angle is come, the capital by reflecting wall optically focused on the time of photomultiplier plate, thereby guaranteed that this device can hole of omission.Ultraviolet source (2) with four ultraviolet lamp tube assemblings connects ballast resistor (10) by lead (9).Ultraviolet lamp tube effective luminous element 1.3M is long, adopts the 8KHZ power supply source.Photelectric receiver (3) is a photomultiplier.Light filter (7) only allows the fairing profit of ultraviolet source to pass through, and does not allow visible light and other scattered beam to pass through.In order to make not stray light electro-detection of other scattered light, light barrier (8) is installed in the both sides of coil of strip, so that stop above the coil of strip and the scattered light of side enters ultraviolet source (2), light barrier (8) is installed on the band steel autotracking unit (11), when being with its meeting of steel autotracking unit (11) and servomotor (12) according to steel rolling, automatically follow up about coil of strip and when swinging up and down, so just avoided the interference of scattered light this device.When hole appears in coil of strip, photomultiplier (3) will be sensed ultraviolet light, this signal will be delivered to computing machine (5) immediately, and computing machine (5) will calculate the lengthwise position of hole at coil of strip with the mistiming of finding hole according to the actual speed and the open rolling time of unit operation.
Claims (1)
1, steel plate hole on-line measuring device, by support (1), be connected in the ultraviolet source (2) on the support (1), photelectric receiver (3), the switch board (5) that is connected by signal wire (4) with photelectric receiver (3), be connected in the light shield (6) on the photelectric receiver (3), be installed on the light filter (7) between photelectric receiver (3) and the ultraviolet source (2), be loaded on the light barrier (8) of photelectric receiver (3) both sides, the autotracking unit (11) that is connected with light barrier (8), the servomotor (12) that is connected on the light barrier (8) is formed, and it is characterized in that: ultraviolet source (2) is gone up by lead (9) and is connected ballast resistor (10); Photelectric receiver (3) is a photomultiplier.
