specific Embodiment approach 1

[0028] Specific implementation mode 1. Combination figure 1 and figure 2Describe this specific embodiment, a detection platform, which includes a reducer 7-1, a transmission mechanism, a housing 7-13, two support rods 7-12, a flat plate 7-9 and a workbench 7-11, the transmission The mechanism includes No. 1 pulley 7-2, belt 7-3, No. 2 pulley 7-4, transmission shaft 7-5, support bearing 7-6, disc 7-7 and connecting rod 7-8; speed reducer 7-1 Set in the housing 7-13, the output shaft of the reducer 7-1 extends out of the side wall of the housing 7-13, and the No. 1 pulley 7-2 is fixed on the output shaft of the reducer 7-1; the supporting bearing 7-6 is fixed on the top of the housing 7-13 to support the transmission shaft 7-5; the second pulley 7-4 is fixed on one end of the transmission shaft 7-5, and the center of the disc 7-7 is fixed on the transmission shaft 7 The other end of -5; the diameter of No. 1 pulley 7-2 is identical with the diameter of No. 2 pulley 7-4, and d...

specific Embodiment approach 2

[0031] Embodiment 2. The difference between this embodiment and the detection platform described in Embodiment 1 is that it also includes a sound isolator 7-10, and the sound isolator 7-10 is fixed on the workbench 7-11 and the flat plate. Between 7-9.

[0032] The sound insulator 7-10 in this embodiment, the mechanical noise during the operation of the reducer and the mechanical device is an important factor affecting the detection accuracy. If the mechanical noise is not handled properly, the redundant signal will be submerged in the mechanical noise, making it impossible to detect the redundant. In this embodiment, a sound isolator made of special materials is added between the turntable and the load, so that the mechanical noise of the motor and the turntable cannot be transmitted to the load, effectively eliminating the influence of mechanical noise on the detection, thereby greatly improving the waste. Detection accuracy.

specific Embodiment approach 3

[0033] Embodiment 3. The difference between this embodiment and the detection platform described in Embodiment 1 or 2 is that the connecting rod 7-8 is used to drive the plate 7-9 to swing, and its swing angle is -25° to + between 25°.

Abstract

The invention discloses a detection station, and an automatic detection device and a detection method for surplus objects of aerospace electronic equipment by using the detection station, and relates to the field of surplus object detection. The invention solves the problems that the conventional detection station applied to the automatic detection process of the surplus objects of the aerospace electronic equipment adopts a surplus object activation mode of mechanical impact to cause low service life of the detection station and further cause low detection safety, and large mechanical noise caused by the mechanical impact causes low accuracy of detecting the surplus objects of the aerospace electronic equipment. The surplus object activation mode of the detection station is carried out by a brake unit, and compared with the conventional detection station adopting the mechanical activation mode, the detection station has long service life to ensure high detection safety; meanwhile, indetection device and the detection method for the surplus objects, a turntable is driven by a reducer, and the mechanical noise is eliminated by a sound insulator, so that the surplus object detection accuracy is greatly improved. The invention also has the capacity of identifying materials of the surplus objects. The invention is suitable for detecting the surplus objects.

Description

technical field [0001] The invention relates to the field of redundant object detection, in particular to a detection table, an automatic detection device and a detection method for redundant objects using the detection table. Background technique [0002] Aerospace electronic equipment is widely used in aviation and aerospace fields, and its reliability directly affects the reliability of satellites, rockets and other devices. Therefore, ensuring the normal operation of aerospace electronic equipment is an important factor to ensure the safety of aviation and aerospace fields. However, in the manufacturing process, due to the production and processing environment and technology, some redundant particles such as metal shavings, solder slag, rosin, sealant, screws, wire skins and copper wires may be encapsulated in the airtight shell of aerospace electronic equipment Inside. Since aerospace electronic equipment is often in a state of weightlessness or works in a severe shoc...
