Translational flip type test fixture

Abstract

The invention discloses a translational flip type test fixture which comprises a clamp frame body, an upper clamp plate body, a lower clamp plate body which is correspondingly under the upper clamp plate body, and a translational flip driving mechanism assembled on the clamp frame body. The lower clamp plate body is mounted on the clamp frame body, the lower clamp plate body and / or the upper clampplate body has a test pin, the upper clamp plate body is mounted on the translational flip driving mechanism, the translational flip driving mechanism drives the upper plate body to translate up anddown or left and right or turn up and down relative to the lower clamp plate body, and the upper clamp plate moves forward to a clamping position of covering the lower clamp plate body or moves back to an avoidance position offsetting from lower clamp plate body in the process of translating or turning relative to the lower clamp plate body. According to the translational flip type test fixture, the problems of space and vibration are solved, the height of the fixture is reduced, at the same time, the taking and placing spaces of a PCBA board are satisfied, the risk of piece collision is eliminated, the PCBA boards does not need to move, the vibration is eliminated, and the direct passing probability of a test is improved.

Description

technical field [0001] The invention relates to the field of testing of electronic equipment, in particular to a translation flip-type test fixture used for clamping PCBA boards. Background technique [0002] Printed circuit board, also known as printed circuit board, often uses the English abbreviation PCB (Printed circuit board), which is an important electronic component, a support for electronic components, and a provider of circuit connections for electronic components. Because it is made using electronic printing techniques, it is called a "printed" circuit board. PCBA is the abbreviation of Printed Circuit Board Assembly in English, that is to say, the product obtained after the empty PCB board passes through the SMT upper part or the whole process of DIP plug-in is called PCBA board. [0003] Among them, the test fixtures used in the test of the PCBA board are generally up and down lift structures or drawer pop-up structures. For the up and down lifting structure, ...

AI Technical Summary

Problems solved by technology

For the up and down lifting structure, the opening is generally small, and the PCBA board is easy to cause collisions during the pick-and-place process. If the opening is large, the height will be too high, which will affect the installation of monitors and other instruments on the production line; The PCBA board is vibrating during the rebound process, which may easily affect the probability of passing the test directly
