Abstract

The invention provides a springboard mechanism, which is used for fixing a PCB and comprises a bottom board, a press board arranged above the bottom board and a switching device used for controlling the opening and closing of the press board. The switching device comprises a first cylinder, a second cylinder, a rotating shaft and a spring, wherein the first cylinder and the second cylinder are separately arranged on one side edge of the bottom board, one ends of the first cylinder and the second cylinder are fixedly connected with the bottom board, the other ends of the first cylinder and the second cylinder are fixedly connected with the press board, the two ends of the rotating shaft are fixedly connected with the first cylinder and the second cylinder, the spring is sleeved on the rotating shaft, one end of the spring is fixedly connected with the first cylinder, and the other end of the spring is fixedly connected with the press board. The springboard mechanism provided by the invention has the advantages of simple structure and good locking effect.

Description

technical field [0001] The invention relates to a spring mechanism, in particular to a spring mechanism of a wave soldering machine. Background technique [0002] Wave soldering refers to the molten solder, usually a lead-tin alloy, sprayed by an electric pump or an electromagnetic pump to form a solder wave peak required by the design. It can also be formed by injecting nitrogen into the solder pool, so that pre-installed components The printed board realizes the soldering of the mechanical and electrical connection between the solder end of the component or the pin and the pad of the printed board through the solder wave. [0003] In wave soldering, the spring plate mechanism is used to fix the PCB board, and the locking effect on the PCB board has a great influence on the quality of welding. If the PCB board is not flat after being pressed, it is easy to cause missing soldering and continuous soldering. Contents of the invention [0004] In order to solve the above tec...
