Abstract

The invention relates to the technical field of display equipment, and discloses a test probe device. The test probe device comprises a support, a supporting piece which is mounted on the support in alifting mode, a first driving device for driving the supporting piece to act relative to the support and a test assembly mounted on the supporting piece. The test assembly comprises a mounting plate,a cutting unit, a sucker disc unit, a grinding unit, an auxiliary probe unit and a test probe unit and a second driving device, wherein the cutting unit, the sucker disc unit, the grinding unit, theauxiliary probe unit and the test probe unit are mounted on the mounting plate, and the second driving unit is used for driving the cutting unit, the sucker disc unit, the grinding unit, the auxiliaryprobe unit and the test probe unit to act and to switch between a test station and a non-test station. The test probe device realizes the detection of an effective display area of a display panel, the test process is saved, the test time is shortened, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of display equipment, in particular to a test probe device.
