Problems solved by technology
The light source used by the known alignment device is visible light. If the edge of the display panel 16 is not evenly cut or interfered by external light, the photosensitive camera will not be able to recognize the alignment mark or will catch the alignment mark by mistake, resulting in poor assembly accuracy of the display and cannot satisfy the needs of clients

The invention relates to an aligning device which is applied to a panel assembling machine and comprises a suction component, a bracket, a sliding rail, a light source component and a light sensing component, wherein the suction component comprises at least one suction nozzle; the bracket is arranged at one side of the suction component and comprises a first end and a second end, and a gap is arranged between the first and the second ends; the sliding rail includes a first sliding rail and a second sliding rail, and is provided with a sliding groove; the first sliding rail is fixed at the first end of the bracket, and the second sliding rail is fixed at the second end thereof; and the light source component is arranged on the sliding rail in a sliding way. An aligning light source of the aligning device is an infrared light source, so as not to be interfered by outside light when a panel is assembled and aligned, so that the image taking quality of the light sensing component can be maintained to be optimum. In addition, the aligning light source of the aligning device can move back and forth on the sliding rail, so that the image taking position can be flexibly adjusted, and the production efficiency of the assembling machine is improved.
Description
technical field [0001] The present invention relates to an alignment device, and in particular to an alignment device whose alignment light source is an infrared light source and which can flexibly adjust an image-taking position. Background technique [0002] With the rapid development of multimedia, many flat panel display technologies have been developed one after another, such as liquid crystal displays. Liquid crystal displays have the characteristics of light and thin appearance, low power consumption, and no radiation pollution. They have been widely used in portable information products such as notebook computers and personal digital assistants (PDAs), and even CRT monitors that have gradually replaced traditional desktop computers. device trends. [0003] Please refer to figure 1 , figure 1 It is a schematic diagram of an alignment device grabbing an alignment mark when a conventional liquid crystal display is assembled. The alignment device 1 includes a suction...
