Translation clamshell test fixture

Abstract

The invention discloses a translation flip-type test fixture, which comprises a fixture frame body, an upper splint body, a lower splint body located below the upper splint body, and a translation flip driving mechanism assembled on the fixture frame body. The lower splint body is installed at the fixture frame, the lower splint body and / or the upper splint body have test needles, the upper splint body is assembled on the translation and flip drive mechanism, and the translation and flip drive mechanism drives the upper splint body to move forward and backward relative to the lower splint body. Translation in the left and right direction and flip in the up and down direction, the upper splint body moves forward to the clamping position that covers the lower splint body or retreats to the avoidance position that is staggered from the lower splint body during the process of translation and flipping relative to the lower splint body . The translation flip-type test fixture of the present invention solves the space problem and the vibration problem, that is, reduces the height of the fixture, and at the same time satisfies the PCBA board pick-and-place space, eliminates the risk of collision, the PCBA board does not need to move, eliminates vibration, and improves the probability of passing the test directly.

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
