Description

FCT test equipment based on tilting mechanism Technical Field The utility model relates to FCT test equipment based on a turnover mechanism. Background The FCT (functional Test) refers to a Test method for providing a simulated running environment (excitation and load) for a Test target board (UUT: unit Under Test) to enable the Test target board to work in various design states, thereby acquiring parameters of the various states to verify the function of the UUT. In short, it is the UUT that is loaded with the appropriate stimulus to measure whether the output response is satisfactory. Typically referred to as functional testing of the PCBA. The FCT test equipment generally needs to manually clamp the PCB in the jig, then press the faller on it to make the test needle contact with the test point position of PCB, the needle bed in the existing equipment adopts vertical lift and rotatory flip's structure to accomplish the contact and the separation with PCB generally, in the vertical lift structure, because the station needs to be located under the faller, in order to make things convenient for personnel to pack into the PCB, just need the sufficient height that the faller risen, can increase the gravitational potential energy of faller like this, and in order to prevent because the gravitational potential energy is too big to lead to the faller to damage the PCB, just need increase buffer gear, the higher the faller just has high requirement to buffer gear, this is certainly increased processing cost, and increase lift stroke also easily makes the mechanism break down. Disclosure of utility model The utility model aims to solve the defects in the prior art and provides FCT test equipment based on a turnover mechanism. The utility model provides a FCT test equipment based on tilting mechanism, includes faller, tool, tilting mechanism, elevating system, tilting mechanism be used for overturning the tool to the below of faller, tilting mechanism include motor, rotation axis, roating seat, rotation axis both ends rotate and wear to establish in the roating seat, the output of motor link to each other with the one end of rotation axis, rotation axis lateral wall and fixed linking to each other in tool one side, elevating system be used for controlling the faller and go up and down. Further, elevating system include slide rail, slider, the slide rail install in the fixed plate surface, the slider link to each other with the faller, slider and slide rail sliding fit. Further, the number of the sliding blocks is two. Further, the needle bed and the buffer mechanism are arranged on the lower end face of the needle plate, the buffer mechanism comprises a plurality of bolts and springs, the bottoms of the bolts penetrate through the lower end face of the needle plate, the springs are sleeved on the bolts, and two ends of the springs are respectively connected with the lower end face of the needle plate and the head of the bolts.
