Cantalever board conveying equipment

Abstract

There is provided a cantilever panel carrier that has a simple structure and requires less cost by constructing clamp carriers with two cantilevers that are adjustable automatically according to the size of a panel to be inspected, and providing a pair of carrier moving units actuating the respective cantilever clamp carriers. In the cantilever panel carrier for carrying a panel between a sub-table and a work table of a liquid crystal (LC) panel inspection device, a moving body moves between the sub-table and the work table by a driving unit, a pair of carrier moving units are provided on the moving body, two moving blocks are capable of moving back and forth in a length direction of the moving body by the carrier moving units, two cantilever clamp carriers face each other in parallel. The two cantilever clamp carriers have one ends that are respectively coupled to the moving blocks and movable by the actuating units. At least two gripping units are attached to each of the cantilever clamp carriers to clamp the panel. The two gripping units are movable in a length direction of the cantilever clamp carrier.

Description

technical field [0001] The present invention relates to a board carrier of a board inspection device, and more particularly, to such a cantilever board carrier by constructing two The clamping and transporting device of the cantilever, and a pair of moving units of the transporting device for activating the respective cantilever clamping and transporting devices have a simple structure and require less cost. Background technique [0002] As is well known in the art, a liquid crystal (LC) panel inspection apparatus performs luminescence inspection using a probe unit to detect line breaks and color defects of the LC panel. In addition, a microscope is used to perform visual inspection. [0003] like figure 1 As shown, this LC panel detection device includes a main body 100, an LC panel supply part 10 formed on the side of the main body 100, a detection part 30 formed next to the LC panel supply part 10, and an LC panel received from the LC panel supply part 10 to The LC pan...

Problems solved by technology

[0015] Another disadvantage of the plate handling device 40 is that if the air cylinder is used as the driving unit 47c, additional pipelines and sensors are required to supply air to the air cylinder, thus making the structure of the LC plate detection device complicated and difficult to control

Also, if the air supply is not uniform for each cylinder, the LC plate 48 cannot be properly clamped

[0016] Another disadvantage of the board handling device 40 is that, since each moving block 46 is moved by a pair of driving units (not shown) connected to both ends of the moving block 46, when the pair of driving units operates out of synchronization, the moving blocks 46 may move unevenly at both ends, causing breakage and abnormal operation of moving block 46 and board handling device 40
