Description

Marking device for forming marked image on radiographic film
Technical Field
The invention belongs to the field of industrial ray detection devices, and relates to a marking device for forming a marked image on a ray negative.
Background
According to the standard requirements of NB/T47013.2-2015 pressure-bearing equipment radiographic inspection, a complete and correct mark image needs to be arranged on the film during radiographic inspection. The mark generally comprises an identification mark and a positioning mark, wherein the identification mark at least comprises an item name, a detection unit, a product number, a welding seam number, a part number, a welding worker code number and a transillumination date. In practice, a full image of a weld on a single substrate requires 40 letters or numbers to be programmed.
There are two methods for forming a marked image on a negative. One is formed by radiation exposure. At present, the most common method is to arrange manually the required information on the negative film on a tape or a cassette by using "type-casting" such as 0, 1, 2, 3, A, B, C, etc. before exposure, then fix the film on the welding line by using a rubberized fabric, and form the marked image after exposure by radiation and dark room processing. This method has the following disadvantages: a film has more marks to be presented, and the manual arrangement on site is time-consuming and labor-consuming; the negative film is easily invalidated due to wrong and missing marks in the arranging process; on-site conditions are not good, such as low temperature, high humidity and weather with much dew, the viscosity of the adhesive plaster is greatly reduced, so that the flame singing and lamp baking are needed, and the special time is spent for changing one or a group of characters; the adhesive tape drops in the exposure process, which causes that the type drops, slides or the type plate is inclined, and the type presses the welding line, so that the welding line image is covered. The patch can be caused by the omission or the mistake of the mark, and the resource waste can be caused by larger working hour, labor and cost.
The other type is formed by natural light exposure, namely, the marking pre-exposure is completed by a certain tool in an office to form a marking image, so that the difficult problems of field type coding and type pasting are avoided. As in chinese patent application No.: 201110312429.0, filing date: 14/10/2011, the invention has the patent name: the invention discloses a film printer, which is characterized in that a film is placed on the plane of an exposure window, a cover plate is pressed downwards to press a contact switch, the contact switch is used for connecting a circuit, and a white light is emitted by a white lamp to complete one-time exposure on the film; then taking out the exposed film, horizontally placing the paper printed with characters on the plane of the exposure window, horizontally placing the film subjected to one-time exposure on the paper printed with characters, and aligning; the cover plate is pressed downwards to press the contact switch, the circuit is connected through the contact switch, the white light is emitted by the white lamp to expose the film, the light penetrates through the printing paper, the light intensity of the part printed with the characters is small, and differential images are formed on the film after the printing.
Chinese patent application No.: CN201921070686.6, application date: 7, month 10 in 2019, the patent name of the invention is: the invention discloses a radiographic film information mark imager, which comprises a computer, a carbon powder printer, a black matrix printing system and a black matrix printing system, wherein the computer is provided with printing information with the size consistent with that of a light source window; cutting the marking information paper tape into a specified size according to the template; the cut information paper tape is corresponding to the negative film, then the information paper tape is put on the upper surface of the light-diffusing plate at the light source window of the instrument, the edge of the unexposed negative film is pressed on the light source window, and the negative film is subjected to light sensing for 1-3 seconds to form a marked image.
Although the two methods can realize pre-exposure to form a marked image and greatly reduce the field workload, the two methods have the defects that the negative film needs to be drawn out and needs to be processed in a darkroom, the false defects and the false exposure of the negative film are easily caused, the implementation steps are complex, and the implementation place is single.

The marking device is externally connected with a mobile phone or a computer, and aims to open display screen editing software by using the mobile phone or the computer, edit welding seam marking information to be displayed and send the welding seam marking information to a display screen.
Preferably, the display screen editing software can be general software for manufacturers and self-developed software, and the software can edit the number range of the characters of not less than 60 letters (Chinese characters).
When the device is used, the control switch 101 is turned on to display the welding seam mark information on a display screen, and the film is exposed by the bright light emitted by the display screen.
Preferably, the display screen mark is displayed as a black character with white background, the film is exposed by using the difference between the brightness of the white part and the brightness of the black part, and after the preset time of the timer unit 104, the control switch 101 is automatically turned off, and the exposure is finished, so that the marked latent image is formed.
The marking device of the invention utilizes the photosensitive characteristic of the film to carry out secondary sensitization on the film after the ray sensitization, so that the information of the welding seam to be expressed is presented on the transillumination film; in addition, in order to get rid of the limitation of the original operation in a darkroom, the display screen is directly arranged on the film cartridge in a built-in mode, the local film is sensitized, and the operation can be completed at any time and any place; in order to improve the use convenience, a computer or a mobile phone is used for connecting a connecting line to edit the film marking information for displaying.
