a camera lens 11 mounted above the ground glass platform;
a blanking film cassette 13 for collecting film, said blanking film cassette being arranged on the side of said wool glass platform remote from said loading film cassette, said blanking film cassette being lower than said wool glass platform.
The feeding film box is cuboid, and the photoelectric switches are uniformly arranged on two adjacent sides of the feeding film box at intervals.
The film baffles are two and are respectively movably arranged on the feeding film box along an X axis and a Y axis.
The ground glass platform sets up the left side of material loading film case, the film transmission gyro wheel is located the ground glass platform with between the material loading film case.
The shading cloth mechanisms are two groups and are respectively movably installed on two adjacent sides of the ground glass platform along an X axis and a Y axis, and the shading cloth mechanisms moving along the X axis direction are located on the right side of the ground glass platform.
The shading cloth mechanism comprises shading cloth 13 and a movable plate 14, one end of the shading cloth is wound on a cloth roller 15, the other end of the shading cloth is fixedly connected to the movable plate, and the movable plate is horizontally movably installed on the ground glass platform.
The film sensor is arranged at the front end part below the feeding film box, the bottom of the feeding film box is made of transparent glass, and the film sensor is an infrared sensor.
The device comprises a photoelectric switch, a film sensor, a film transmission roller, a spring electromagnet, an LED lamp bank, a film blackness sensor, a shading cloth mechanism and a camera lens, and is characterized by further comprising a controller, wherein the photoelectric switch, the film sensor, the film transmission roller, the spring electromagnet, the LED lamp bank, the film blackness sensor, the shading cloth mechanism and the camera lens are in communication connection with the controller.
The film sensor is positioned on the right side of the spring electromagnet.
The film blackness sensor is positioned on the right side of the LED lamp bank.
The working mode of the full-automatic industrial radiographic film reader mechanism is as follows: the workman is in putting into the material loading film holder with the film, after pushing away the left front corner of film to the material loading film holder through the film baffle, by spring electromagnet lifting material loading film holder, film transmission gyro wheel and film contact, utilize the coefficient of friction between film transmission gyro wheel and the film and the coefficient of friction between film and the film each other different, transmit the film to the ground glass platform on, promote the film to ground glass platform left front position through shading cloth mechanism, shoot by camera lens, shoot and accomplish again and push away the film to unloading film holder by shading cloth mechanism, accomplish once and shoot. Repeating the above process until the film in the feeding film box is shot.
The position of photoelectricity fast switch is arranged according to film size specification, puts into material loading film box with a pile of films by the staff, pushes away the film through the film baffle behind the left front corner of film to material loading film box, shelters from by film baffle final position through photoelectric switch this moment and learns film size, transmits to the controller. The specification information of the film can be known by shielding the photoelectric switch, so that the step of manual measurement is avoided, the time is greatly saved, and the operation steps are reduced.
When the spring electromagnet and the bottom of the feeding film box do not receive an excitation signal sent by the controller, the spring electromagnet is electrified to suck the bottom of the feeding film box, so that the film transmission roller does not contact with the film. After receiving the excitation signal, the magnetic field is cut off, and the feeding film box is lifted by the spring, so that the film transmission roller is in contact with the film and transmits the film to the ground glass platform. The spring electromagnet is used for controlling whether the films are contacted with the film transmission roller or not, on one hand, the spring has a certain reset stroke, and the film transmission roller can be still contacted with the films when the thickness of the films is reduced until the last film is used up. On the other hand, the spring has a certain buffering effect, so that the impact or the force is not too large when the film is in contact with the film transmission roller, and the damage to the film transmission roller and the film can be avoided.
After the film is conveyed to the ground glass platform, the film blackness sensor detects the film blackness, and the brightness of the LED lamp set is adjusted according to the blackness. Meanwhile, the shading cloth mechanisms are respectively pushed forwards to a specified position from a zero position along the direction of an X, Y shaft according to the specification and the size of the film. The brightness of the LED lamp bank is adjusted by detecting the thickness of the film through the blackness sensor, so that the lamp bank can reach the brightness most suitable for shooting through each film, the clearest image is obtained, and judgment is facilitated.
After the shading cloth mechanism reaches a designated position, the LED lamp group controls brightness to light up through the blackness value detected by the film blackness sensor 9, the camera lens shoots the film, and then the shading cloth mechanism in the X-axis direction continues to advance, so that the film falls into the blanking film box. Then the two groups of shade cloth mechanisms return to respective zero positions. When all the films are taken out, the film sensor detects that the films are used up and sends out a signal prompt. The shading cloth mechanism can push the film to a shooting position on one hand, and can push the film to a film discharging box after shooting is finished on the other hand. Two different functions can be completed through the shading cloth mechanism, the overall operation efficiency is improved, the complexity of the mechanism and the overall size of the mechanism are reduced, and the disassembly and the assembly are convenient.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, it should be noted that, for those skilled in the art, many modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
