Abstract

The invention provides a cam jacking structure for a tower-type jig for PCBA testing. The cam jacking structure for the tower-type jig for PCBA testing mainly comprises a motor, a rotary rod, a cam, supporting plates, a belt wheel, a first bearing, a second bearing, a washer and fixing blocks. The motor drives the belt wheel to rotate, and then the rotary rod and the cam are driven to rotate integrally. Due to the structural characteristics of the cam, in the periodical rotating process, the supporting plates can be ejected by a cam pulley at the tail of the cam to move upwards. For a non-standard jig manufactured according to special requirements of a customer, an upper mold of the tower-type jig can be lifted and lowered easily, and thus the testing process is conducted smoothly.

Description

technical field [0001] The invention relates to the field of printed circuit board testing, in particular to a cam jacking structure of a tower fixture for testing PCBA. Background technique [0002] PCB (Printed Circuit Board), the Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. PCBA (Printed Circuit Board Assembly) is a printed circuit assembly board that uses SMT (Surface Mount Technology, surface mount technology) on the PCB board and passes through the DIP plug-in. [0003] After the PCBA board is installed, a performance test is required to ensure the performance of the PCBA. An auxiliary equipment will be used in the PCBA board test process to facilitate the fixation and accurate repeat positioning of the measured product in the test instrument to improve test efficiency. In the PCBA test process, a...
