Flying probe tester utilizing planar motor

Abstract

The invention specifically relates to a flying probe tester utilizing a planar motor and solves the problem of an existing flying probe tester that the testing precision cannot be satisfied due to an unreasonable structure. A machine frame is internally provided with a planar motor stator, a probe loading device, a circuit board positioning clamp and a lifting platform. The lifting platform is provided with a fixed probe. The probe loading device comprises a rotor body. The rotor body is provided with a support. A linear motor and a transmission belt are fixed at two sides of the support. The transmission belt is provided with an insulating block. A probe assembly is arranged on the lower end of the insulating block. The probe assembly comprises a sleeve. A probe penetrates through the sleeve. A buffering spring, in contact with the insulating block, sleeves the tail end of the probe. The probe is composed of a probe body and a probe sleeve, and a probe buffering spring is arranged between the probe sleeve and the probe body. According to the invention, the planar motor is adopted for realizing specific angle loading, an elastic contact circuit board, a programmable-control loading pressure, good conductivity, voltage resistance and insulation.

Description

technical field [0001] The invention relates to a circuit board testing device, in particular to a flying probe testing machine using a planar motor. Background technique [0002] The flying probe testing machine is installed on the X-axis and Y-axis with motor-driven probes that can move independently and quickly, and uses the controllable movement of the probes in the Z-axis direction to contact the solder joints of the PCB board and perform electrical measurements. equipment. Due to the functional requirements of the flying probe testing machine, the two ends of the Y-axis are generally erected on two X-axes respectively, and the span is relatively large, driven by two motors on the X-axis (dual drive) or by a single X-axis Motor drive (single drive). In order to improve testing efficiency, flying probe testing machines generally have multiple probes, and the number of X-Y axes increases accordingly. It is because the number of axes of the flying probe testing machine ...
