The invention relates to the circuit board detection equipment technology field and discloses a multilayer circuit board detecting device. The device comprises a pedestal. Left and right ends of a topsurface of the pedestal are fixedly provided with fixed rods. The top surface of the pedestal is fixedly installed with a double-shaft motor located between the two fixed rods. Left and right ends ofan output shaft of the double-shaft motor are fixedly connected to sleeve rings. A top and a bottom of each sleeve ring are fixedly provided with a long pressing plate and a short pressing plate. Byusing the multilayer circuit board detecting device, when the double-shaft motor rotates, a long pressing block and a short pressing block intermittently apply upward pressure to a stress block so that a top table vibrates up and down with different amplitudes. When the top table vibrates up and down, a movable vibration tube also moves up and down relative to the fixed rods, and bumps on the leftand right sides of an inner cavity of the movable vibration tube provide pressure to a pulley. The movable vibration tube moves to the left and right relative to the fixed rods so as to achieve a purpose that the top table vibrates with different amplitudes and vibration waves. And then, the circuit board fixed above the top table can be high-efficiently vibrated.
Description
technical field [0001] The invention relates to the technical field of circuit board detection equipment, in particular to a multilayer circuit board detection device. Background technique [0002] Multilayer circuit boards have the advantages of high assembly density, small size, and light weight. Since the production process of multilayer circuit boards is more cumbersome than other circuit boards, multilayer circuit boards require reliable detection methods. [0003] In order to detect the welding firmness of the electrical components inside the circuit board, people usually fix the circuit board on a vibration table for vibration detection, and the electrical components that are not welded firmly inside the circuit board can be shaken off by shaking the vibration table. There is usually only one vibration direction of the vibration table, which is either a transverse wave vibration or a longitudinal wave vibration, and the amplitude of the existing vibration table cannot...
