Description

Horizontal flying probe tester Technical Field The utility model relates to the field of circuit board flying probe testing, in particular to a horizontal flying probe testing machine. Background The traditional flying probe tester is usually a vertical tester, and when in detection, a circuit board is vertically clamped, and the flying probe horizontally moves to be vertically contacted with a contact on the circuit board to carry out open and short circuit detection of a circuit and a hole or Kelvin detection. Because the FPC soft board is soft and easy to deform, the tooling fixture of the traditional flying probe tester is easy to deform and bend when clamping the FPC soft board. Therefore, the tooling fixture of the traditional flying probe tester is easy to cause easy damage to FPC lines. And the size specification of the tested FPC flexible board is limited by the size of the workbench, and when testing a large or ultra-large FPC flexible board, the edge of the FPC flexible board is deformed and bent outside the workbench, so that the circuit of the FPC flexible board is damaged, and therefore, a tool is required to be customized according to the shape and the size specification of the FPC flexible board. The fixture of the traditional flying probe tester is difficult to adapt to large-scale FPC flexible boards with various specifications. In order to ensure the accuracy of the flying probe displacement of the traditional flying probe tester and to realize the alignment of the flying probe with the welding spot, a motion mechanism of the flying probe tester is generally driven by a high-accuracy screw rod. The plurality of screw nuts on the screw rod synchronously displace, so that the flying probe detection modules synchronously displace to detect the circuit boards. Because the displacement speed and the displacement direction of the screw rod nut on the screw rod are the same, each flying probe detection module can only synchronously move. The flying needle detection modules cannot independently control independent movement, the movement precision of the flying needle detection modules is difficult to be separately and independently controlled, a long high-precision screw is high in price, and vibration and friction during the screw working can not be prevented from influencing the movement precision of the flying needle. Therefore, the utility model provides a horizontal flying probe tester, which solves the problem that the existing flying probe tester cannot detect a plurality of FPC flexible boards of different types at the same time with high precision, and avoids the influence of vibration and friction of the traditional screw rod on the alignment precision of the flying probe.
