Detailed Description
The utility model discloses a LED screen visual detection auxiliary device is shown as figure 2, including workstation 9 and detection device 6. As shown in fig. 3-5, a base 61 of the detecting device 6 is mounted on the upper portion of the rear side of the workbench, a longitudinal detecting arm 615 is mounted on the base 61, a guide rod 63 is mounted on the upper portion of the detecting arm 615, two guide rods 63 are provided, one end of each guide rod 63 is mounted on a vertical plate 62, and the lower end of each vertical plate 62 is fixed on the detecting arm 615. A sliding seat 616 is slidably mounted on the guide rod 63, a through hole is formed in the sliding seat 616, the sliding seat 616 is slidably mounted on the guide rod 63 through the through hole, a locking knob 69 is mounted on the sliding seat 616, the locking knob 69 is screwed downwards to abut against the detection arm, locking of the sliding seat 616 can be achieved, the detection device 6 is suspended on the upper side of the equipment in a single-arm mode, and the camera 68 for detection can be adjusted in position along the guide rod 63 and locked through the locking knob 616. A horizontal sliding table 65 is arranged on one side of the sliding base 616, a longitudinal sliding table 66 is arranged on the outer side of the horizontal sliding table 65, a camera 68 is arranged on the outer side of the longitudinal sliding table 66, the camera 68 is fixed on the longitudinal sliding table 66 through a camera mounting plate 613, and a light source 67 is arranged on the lower portion of the camera 68.
The working principle is as follows: be equipped with horizontal limit baffle 4 and vertical limit baffle 7 on workstation 9 to limit baffle restriction LED screen product position on workstation 9, detection device 6's slide 616 moves along the direction of below detection area 2, thereby drives camera 68 and carries out longitudinal movement, locks when reacing the detection position. Instead of using a sliding table with higher precision for precise position adjustment, the sliding table is used for precise adjustment of the height of the camera, and the sliding table is a universal standard sliding table, as shown in fig. 6 and 7, the horizontal sliding table 65 realizes precise position adjustment in the horizontal direction through a horizontal rack 612, and is locked through a horizontal adjustment knob 610 after being adjusted to a proper position; the vertical sliding table 66 realizes vertical adjustment of the camera through the vertical rack 611, and is locked by a height adjusting knob after being adjusted to a specified position.
