Description

Technical Field

[0001] The present invention relates to the technical field of industrial manufacturing, and particularly relates to a three-piece automatic film combining and pressing device and a method thereof. Background Art

[0002] Americium-241 is an actinide isotope commonly used in industry. It is an α emitter. During the decay process, in addition to releasing three groups of α particles (Eαmax = 5.48 MeV), it can also release γ rays and X rays with a certain amount of energy. It has a long half-life (432.2 a) and relatively stable properties, and is widely used in smoke detectors, poison gas detectors, logging neutron sources, low-energy photon sources, or as the heat source of a 1-5 watt small isotope thermoelectric generator, etc.

[0003] This americium-241 α source can be used for certain poison gas sensing alarms and vehicle exhaust detection. The principle is that the α rays generated by the americium-241 source ionize the air to generate an electric current, and the poison gas and vehicle exhaust with specific components change the strength of the electric current after passing through the ionization field generated by the α rays, thereby realizing the sensor alarm.

[0004] This kind of americium-241 α source is a thin sheet with a gold-palladium surface layer made of gold-palladium and a silver bottom lining, and the center is wrapped with americium oxide raw materials. During the production process, first, three-piece blocks are obtained, and after repeated wrapping and rolling, a circular radioactive source thin sheet is finally stamped. Among them, the film combining and pressing process of the three-piece blocks is the most complex.

[0005] Currently, the three-piece blocks are all made by manual film combining and pressing, and there are the following problems: (1) Manually placing the source sheets will cause the positions of each source core to be not fixed, and it is necessary to repeatedly determine the active area range in the subsequent stamping process, wasting a lot of time. (2) Manual operation mainly relies on experience for temperature control, and it is necessary to control the hydraulic press while burning, and it is difficult to master the pressing time well, and there is a safety risk of mechanical injury. (3) The operation space for manual film combining and pressing is limited, and it is difficult to complete multi-person cooperation. The work efficiency is low, and a certain amount of radiation dose will be received. (4) The production site is a fume hood, and it is easy to produce the phenomenon that the source sheets fall to the ground and are lost during production. (5) There are safety hazards in the gas stove. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0045] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention in conjunction with the drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0046] Such as Figure 1As shown in the figure, the three - time block automatic film - combining and pressing device provided by the present invention includes a first vibratory bowl 6 (source - piece vibratory bowl) for carrying source pieces; an infrared induction and identification system; a suction system (manipulator) 3 responsible for transferring materials; a second vibratory bowl 7 (silver - block vibratory bowl) for carrying silver blocks; a third vibratory bowl 8 for carrying gold - palladium surface layers; a fourth vibratory bowl 9 for carrying silver positioning frames; an assembly groove for combining the semi - finished three - time blocks; a heating system 10 for heating the semi - finished three - time blocks; a three - time block pressing system 11; and a gas - path system for providing power to the suction system and all vibratory bowls.

[0047] The suction system 3 is installed on the outer - frame structure 1, and the first vibratory bowl 6, the second vibratory bowl 7, the third vibratory bowl 8, and the fourth vibratory bowl 9 are installed on the box body 5. A load - bearing base 2 is provided at the bottom of the box body 5.

[0048] After the infrared induction and identification system identifies different surfaces of the materials, under the action of the inclination angle of the vibratory - bowl track, the source - piece vibratory bowl blows the source pieces with the reverse side up (gold is the front side, silver is the reverse side) and irregular - shaped source pieces to the bottom of the vibratory bowl by the gas - path system to vibrate and turn them over again. The source pieces with the front side up are conducted to the suction system. The silver - block vibratory bowl blows the silver blocks with the reverse side up (the flat surface is the front side, the convex surface is the reverse side) to the bottom of the vibratory bowl by the gas - path system and the track inclination angle to vibrate and turn them over again. The silver blocks with the front side up are conducted to the suction system. The gold - palladium surface - layer vibratory bowl blows the gold - palladium surface layers with the reverse side up (silver is the front side, gold is the reverse side) and irregular - shaped gold - palladium surface layers to the bottom of the vibratory bowl by the gas - path system to vibrate and turn them over again. The gold - palladium surface layers with the front side up are conducted to the suction system. The silver positioning frames are blown to the bottom of the vibratory bowl by the gas - path system and the track inclination angle for the irregular silver positioning frames, and the regular silver positioning frames are conducted to the suction system of the vibratory bowl. After the suction system places the correctly identified materials in the order of silver block - source piece - gold - palladium surface layer - silver positioning frame in the assembly groove in sequence, the manipulator picks them up and places them in the heating coil of the heating system. After heating to the appropriate temperature, the manipulator clamps them out, puts them into the pressing equipment to be flattened, and then the three - time block is pushed out through the platform, and thus the preparation of one three - time block is completed.

[0049] The vibratory bowls for carrying materials adopt a threaded - track design. The track spirals upward from the bottom of the vibratory bowl and is connected to the gas - path system and the infrared induction and identification system for easy identification of materials. The vibratory bowls are made of hard plastic material to reduce the wear of materials caused by vibration. The infrared induction and identification system can not only identify whether the materials are in place but also has a certain ability to distinguish colors, which can prevent the source pieces and silver blocks from being placed reversely. The suction system includes a manipulator for transferring silver blocks and un - combined three - time blocks; several vacuum suction nozzles for sucking source pieces, gold - palladium surface layers, and silver positioning frames and stacking them in sequence. The control panel 4 can control the entire combined pressing process, monitor the process in real time, and perform manual operations when necessary.
