Description

Probe block for panel testing {PROBE BLOCK FOR TESTING PANEL}

The present invention relates to a probe block for panel testing, and more particularly, in a probe block for an aging test of a display panel, a head block can be easily attached and detached from a housing block, so that quick replacement of the head block is possible without a separate tool or jig. It relates to a probe block for panel testing to be made.

In general, display panel products are required to perform various performance and quality inspections after assembly is completed in an assembly line and before assembly into a finished product, and one of the inspections is an aging process for testing the durability of the product.

In the aging process, a number of products are accommodated in the aging chamber to provide an environment above the allowable temperature (eg, 50 to 90°C) for a certain period of time (eg, 30 to 180 minutes), while selecting the image quality and whether the attached circuit is defective. Is, of course, tested for harsh conditions.

In such an aging process, an electrical signal is applied for a predetermined period of time while the display panel is transferred and mounted on a pallet in the aging chamber to check whether it operates normally.

The pallet is provided with a support to which several probe blocks are coupled, and a display panel is inserted and fixed in a space secured as the coupled probe blocks are moved up and down, and an electrical signal is applied through a probe attached to the probe block. Is made.

As the probe, various types of probes such as FPCB (Flexible Printed Circuit Board), MEMS FPCB, blades, and pins are used, but it is essential to replace the probe in the probe block due to deformation or damage of the probe due to a long test. .

However, the probe is a very precisely manufactured part, and the operation of replacing the probe from the probe block is very cumbersome and difficult, and it takes a lot of work time. In order to solve this problem, a method of attaching a probe to a separate block and replacing the block to which the probe is attached from the probe block using a screw coupling means has also been proposed. However, since this method also uses a screw coupling means, it takes considerable time to replace a separate block from the probe block, thereby reducing work efficiency.

In order to solve this problem, there has been an attempt to facilitate the replacement operation using the magnetic force of a magnet, and a related invention (Korean Patent No. 1795615) is shown in FIG. 1.

Correspondingly, a plurality of second magnets M are provided on the upper surface of the head block 200 so that the housing block 100 and the head block 200 are coupled and separated by magnetic force.

However, when the probe block of the magnet fixing method is combined, it is relatively easily combined by the magnetic force of the strong magnet, but when it is separated, it is necessary to use a specially manufactured precision jig, not a general tool, to apply a force that exceeds the magnetic force of the magnet. It has a disadvantage. Therefore, there was an inconvenience that a dedicated jig for separating the probe block had to be provided at all times in the workplace or the operator had to carry it, and in the end, there was no significant improvement in work efficiency compared to the conventional screw-coupled probe block.
