Adjustable circuit board fixing device

Abstract

An adjustable circuit board fixing device disclosed by the present invention comprises a base plate, one side of the base plate is fixedly connected with an extension plate, the extension plate and one end of the bottom of the base plate are fixedly connected with suckers through a plurality of cylinders, one end of the top of the base plate is rotatably connected with a rotating column, and the outer part of the rotating column is fixedly sleeved with a lantern ring. Three connecting rods are uniformly and fixedly connected to the outer side of the lantern ring, fixing frames are fixedly connected to the ends, away from the lantern ring, of the three connecting rods, and circuit board fixing mechanisms are arranged in the three fixing frames. By arranging the circuit board fixing mechanism, circuit boards with different sizes can be fixedly clamped, so that the device can be suitable for processing the circuit boards with different models; and by arranging the three fixing frames, the continuity of circuit board machining work can be guaranteed, the time wasted by waiting for spot welding cooling solidification can be effectively avoided, and the circuit board machining efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of circuit board production, and particularly relates to an adjustable circuit board fixing device. Background technique [0002] The names of circuit boards are: ceramic circuit board, alumina ceramic circuit board, aluminum nitride ceramic circuit board, circuit board, PCB board, aluminum substrate, high frequency board, thick copper board, impedance board, PCB, ultra-thin circuit board, ultra-thin circuit board Thin circuit boards, printed (copper etching technology) circuit boards, etc. The circuit board makes the circuit miniaturized and intuitive, and plays an important role in the mass production of fixed circuits and the optimization of the layout of electrical appliances. Circuit boards are divided into three major categories: single-sided, double-sided, and multi-layer circuit boards according to the number of layers. [0003] In the production and processing of circuit boards, workers are requir...

AI Technical Summary

Problems solved by technology

[0003] During the production and processing of circuit boards, workers need to install parts on the circuit board by spot welding or bonding. In this process, it is often necessary to use circuit board fixing devices to fix the circuit board to prevent spot welding Or the phenomenon of deviation occurs during bonding, but most of the existing circuit board fixing devices are fixed in size, and different types of circuit boards need to use different sizes of fixing devices, which is troublesome; moreover, workers carry out double-sided circuit board During the above operations, it is necessary to complete the operation on one side first, then wait for the spot welding or bonding to cool and solidify, then remove the circuit board from the fixing device and turn it over, and then use the fixing device to fix it before the operation on the other side , not only the operation is cumbersome, but also it takes a certain amount of time to wait for spot welding or bonding to cool and solidify, which leads to insufficient coherence in the processing of circuit boards and affects the production efficiency of circuit boards
