Automatic packaging device for producing and packaging digital-to-analog converter

Abstract

The invention discloses an automatic packaging device for producing and packaging a digital-to-analog converter. The automatic packaging device comprises a platform and frames, the frames are fixedly connected to the left end and the right end of the front side of the lower end of the platform, and a positioning mechanism is arranged above the frames; the positioning mechanism comprises a first sliding block, an inclined rod, a clamping plate, a first transverse rod, a hydraulic cylinder, a second spring, a supporting rod, a rolling wheel, a base plate and a bottom plate, the bottom plate is fixedly connected to the lower portion of the supporting rod, and the two sides of the second spring are fixedly connected with the bottom plate and the first sliding block correspondingly. The automatic packaging device for production and packaging of the digital-to-analog converter is scientific and reasonable in structure and safe and convenient to use, the circuit board cannot move through cooperation of a hydraulic cylinder, a first sliding block, an inclined rod, a clamping plate, a second conveying belt, a rolling wheel base plate, the digital-to-analog converter and the circuit board, and center positioning of the circuit board is guaranteed through left-right synchronous movement. The problem that position fixation cannot be accurately ensured when packaging and welding between the digital-to-analog converter and the circuit board are carried out is avoided.

Description

technical field [0001] The invention relates to the technical field of packaging, in particular to an automatic packaging device for digital-to-analog converter production and packaging. Background technique [0002] The digital-to-analog converter is mainly composed of digital registers, analog electronic switches, bit weight networks, summation operational amplifiers, and reference voltage sources (or constant current sources). The analog electronic switch makes the bit with a digital value of 1 generate a current value proportional to its bit weight on the bit weight network, and then the operational amplifier sums each current value and converts it into a voltage value, while the digital-to-analog converter produces The process usually needs to be packaged with the circuit board, and packaging is the process of assembling the integrated circuit into the final product of the chip. [0003] Although the existing technology can carry out the packaging operation of the digi...
