A flying probe testing machine and its flying probe module

Abstract

The invention discloses a flying probe testing machine, which includes a machine base, a plurality of support rods are equidistantly and symmetrically installed on one side of the support rod, and double surrounding rails are jointly installed on the upper ends of the plurality of support rods. A transport frame is installed on the base, and a belt conveyor is installed in the transport frame; the invention also discloses a flying probe module, which includes a driver installed on a screw rod, and a slide rail column is installed on one side of the driver , two square slide holes are symmetrically opened in the slide rail column. The present invention realizes the automatic cycle feeding through the cooperation of the double surrounding rails and the pinch pipe, the transmission disc and the transmission chain, realizes the functions of automatic straightening, automatic fixing and automatic positioning through the guide splint, the controllable baffle and the inner concave calibration roller, and through the separation Realize automatic sorting to the board, which is more efficient and reduces labor force. The half-split contact pin combined with conductive shrapnel and insulation realizes low-voltage and low-impact contact, reducing the possibility of damaging the circuit board.

Description

technical field [0001] The invention relates to the field of circuit board testing equipment, in particular to a flying probe testing machine and a flying probe module thereof. Background technique [0002] Flying probe test is one of the important means of electrical testing at present. It can quickly move to the component pins through the probe under the driving mechanism composed of multiple motors for contact testing, without manual testing one by one, which can increase the number of components on the circuit board. The efficiency of device parameter detection can quickly identify missing soldering, damage, short circuit, etc., but during flying probe test, since the soldered solder cannot be completely uniform, it will cause the probe to easily squeeze the solder on the pin when it contacts the pin. cause damage, thereby affecting the quality of the circuit board. [0003] The existing flying probe testing machine and flying probe module are usually single manual boar...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the disadvantages in the prior art that the efficiency of manual layout is low and the labor load is large, and the soft contact can effectively reduce the impact force but cannot effectively reduce the pressure, which still leads to loosening of the pins and solder, and proposes A flying probe testing machine and its flying probe module
