Embodiment Construction

[0009] According to the requirements of GJB, the part number, part batch number, part serial number, and date of transillumination are required to be marked on the fluoroscopy negative. At present, most of them use small lead characters on the film when exposing the film, but this method is efficient. Low, and the placement of fonts is also very limited. The present invention specifically studies the above-mentioned defects, and obtains a film printing machine which can transfer the characters on the paper to the film used for radiographic inspection, and can make permanent marks on the negative film. like figure 1 As shown, the entire film printer is a rectangular box structure, which is divided into a red light room, a white light room, a circuit room and an exposure room. The red light room is located above the circuit room, and the two rooms communicate with each other; the white light room is located below the exposure room, and a white light-transmitting plate is arrang...

Abstract

The invention relates to a film printer The whole film printer has a rectangular box structure and is divided into a red light chamber, a white light chamber, a circuit chamber and an exposure chamber, wherein the red right chamber is positioned above the circuit chamber and communicated with the circuit chamber; the white right chamber is positioned below the exposure chamber, and a white light-transmission plate which is double-layer glass is arranged between the white right chamber and the exposure chamber; the red right chamber and the exposure chamber are positioned on the same plane, the plane which is positioned on one side of the exposure chamber is an exposure window, and a contact switch is arranged above the exposure window and connected with a time relay; and a cover plate is arranged above the exposure window, and one end of the cover plate is connected with a box body which is positioned at one end of the exposure window in a movable manner. A method comprises the following steps of: during transmission, covering an area, in which words are to be printed, of a film; secondarily exposing the film after exposure; and transfer-printing the words on the film. By adoption of the method, normative words can be printed on the film, storage and future retrieval are facilitated, and working efficiency can be improved.

Description

technical field [0001] The present invention relates to a film printer. Background technique [0002] According to the standard requirements, in actual production, when fluoroscopy is performed, that is, when the film is exposed, a large number of marks need to be made on the film, such as: batch number, serial number, part number, etc. of the parts, so as to facilitate the traceability of quality records in the future. At present, the marking method is to place typefaces on the negative film and expose them simultaneously during perspective. However, the efficiency of this method is too low, and the text fonts placed are also very limited. SUMMARY OF THE INVENTION [0003] In order to overcome the above-mentioned defects, the technical problem to be solved by the present invention is to provide a film printing machine which is simple in operation, fast in printing, unlimited in character fonts, and can be placed at will as required. [0004] A film printing machine, the ...
