Technical Field

The invention relates to the technical field of crimping detection of display panels, in particular to a three-axis adjusting device of a pressure head.

Background

In the manufacturing process of various display panels such as TFT, LTPS, AM-OLED, etc., it is necessary to perform optical inspection on the display panel, for example, to check whether the panel has defects such as color mura and bright and dark spots.

Optical inspection is a common inspection means for substrate raw materials such as glass substrates and semi-finished products in the liquid crystal industry. Generally, an optical detection instrument is adopted to photograph a detected substrate to obtain a gray image of the detected substrate, and then the gray image is analyzed to determine whether a dead pixel exists on the detected substrate and the accurate position of the dead pixel.

The optical inspection includes many test items, some of which require the display panel to be lit up (i.e., a screen-on operation) for inspection. When the screen is clicked, the circuit board and the display panel need to be aligned and pressed through the pressure head.

At present, the alignment process is mainly realized by adjusting the position of a pressure head, namely, the pressure head is translated and horizontally rotated. The adjusting mechanism of the existing pressure head has sliding friction when the pressure head is horizontally rotated, and needs to be locked by a screw to realize positioning when the pressure head is rotated to a corresponding position, so that the adjusting time is long.

In view of the above-mentioned drawbacks, the present designer is actively making research and innovation to create a new type of three-axis adjustment device for a pressure head, so that the device has more industrial utility value.

The ram mounting plate 210 is configured to mount the ram 100, the ram mounting plate 210 is connected to the first moving plate 230 in a rolling manner, and the ram mounting plate 210 is connected to a rotation adjusting assembly configured to drive the ram mounting plate 210 to rotate relative to the first moving plate 230. The first moving plate 230 is slidably connected to the second moving plate 240, and the first moving plate 230 is connected to a first translating assembly configured to drive the first moving plate 230 to translate along a first direction relative to the second moving plate 240.

According to the invention, the pressure head mounting plate 210 is connected with the first moving plate 230 in a rolling manner, and the pressure head mounting plate 210 can rotate relative to the first moving plate 230 in a rolling manner under the driving of the rotation adjusting assembly, so that only rolling friction exists between the pressure head mounting plate 210 and the first moving plate 230, and the rolling friction is lighter than sliding friction, thereby accelerating the adjusting speed of the pressure head 100.

In the rolling connection mode of the ram mounting plate 210 and the first moving plate 230, the ram mounting plate 210 is rotatably connected with the shaft lever 211 perpendicular to the ram mounting plate, the shaft lever 211 is connected with the ram mounting plate 210 through a bearing, the shaft lever 211 is fixed on the first moving plate 230, the first moving plate 230 is embedded with a plurality of rollers 212 with different rolling directions, and the bottom surface of the ram mounting plate 210 is in contact with the rollers 212.
