Problems solved by technology

[0011] However, in such an alignment device, even if the fluid supplied to the two pushers arranged on opposite sides with respect to the panel mounting part or the pushers spaced apart from each other in the extending direction of the corresponding side There is a small difference in pressure, which also makes a difference in the pressing force of the pusher
As a result, the object to be inspected cannot be moved accurately, and accurate positioning cannot be performed

Embodiment

[0088] refer to Figure 1 ~ Figure 4 , the test device 10 uses a display panel as a flat panel to be inspected as a flat panel to be inspected as a liquid crystal display panel such as a liquid crystal display panel (see Figure 4 , 7, 9, etc.), and the object 12 to be inspected is connected to a predetermined circuit, thereby being used as a device for performing an electrical test such as a lighting inspection.

[0089] The object 12 to be inspected has a rectangular shape, and also has a plurality of electrodes on edges corresponding to several sides of the rectangle. Hereinafter, for easy understanding, a configuration in which the object 12 to be inspected has a long rectangular shape in the X direction will be described. In the illustrated example, the object 12 to be inspected has a plurality of electrodes at intervals in the longitudinal direction of two edges corresponding to adjacent sides of the rectangle, respectively, at intervals of the corresponding edges.

Abstract

The invention provides a test device for a plate-shaped object to be inspected, which can accurately locate the object to be inspected and has low manufacturing cost. The alignment device suitable for the test device includes: a first pushing mechanism and a first positioning mechanism, which are respectively arranged on one side and the other side of a pair of opposite sides of the panel bearing surface, and in the extending direction of the corresponding side The upper part is arranged at intervals; the second pushing mechanism and the second positioning mechanism are respectively arranged on one side and the other side of the opposite pair of sides of the panel bearing surface. The pushing mechanism and the positioning mechanism are respectively located at the same height position as the panel bearing surface, and respectively include a pressing member located outside the panel bearing surface and a driving mechanism for advancing and retreating the pressing member relative to the panel bearing surface. The drive mechanism of each positioning mechanism holds the position of the said pressing member in the said X direction or the Y direction so that the holding state can be released.

Description

technical field [0001] The present invention relates to an apparatus for testing a flat-shaped object to be inspected such as a liquid crystal display panel. Background technique [0002] A device for performing a lighting test on a display panel such as a liquid crystal display panel has a probe unit for energizing the object to be inspected, and in particular has a positioning function (that is, an alignment function) for positioning relative to the tip of the contact . [0003] Generally speaking, this device includes: a panel bearing part such as an inspection workbench and a workpiece workbench; a worktable moving mechanism for moving the panel bearing part in three directions XYZ and rotating around the θ axis extending in the Z direction; The probe unit is placed above the panel mount. [0004] When positioning, the object to be inspected is adsorbed on the panel carrying part in a manner that can release the adsorption. In this state, the panel carrying part is mov...
