Abstract

The invention discloses an automatic retractor device comprising a machine body (6) and a spring (5), wherein the spring (5) is arranged in the machine body (6); one end of the spring (5) is connected with the machine body (6), and the other end of the same extends out of the machine body (6) and is provided with a first supporting part (2) and a second supporting part (4) with height lower than that of the first supporting part (2). The automatic retractor device has the advantage of capability of supporting a printed circuit board and enhancing the welding quality.

Description

technical field [0001] The invention relates to an automatic telescopic device, in particular to an automatic telescopic device for a reflow soldering machine. Background technique [0002] Surface mount technology is a new generation of electronic assembly technology, which compresses traditional electronic components into devices with only a few tenths of the volume, so as to achieve high density, high reliability, miniaturization, low cost and production efficiency of electronic product assembly. automation. Surface mount is a key step in the transfer production of printed circuit boards. More than 75% of the components on the printed circuit board are fixed on the circuit board by surface mount, and less than 25% are completed by manual assembly. [0003] The main process of surface mounting of printed board components is: printing solder paste on the component surface, patching, and reflow soldering. Printing solder paste is printed on the component surface of the pri...
