New Description: [New Technology Field] This creation is about a backlight source device, especially an adjustable backlight source device for visual inspection of liquid crystal display panels. [Prior Art] Pressing, the backlight source device for visual inspection of the liquid crystal display panel is used to provide a light source. When the signal capture camera captures the image of the panel under test, the signal is processed by the computer for back-end data processing to identify the measured object. The integrity of the panel, to confirm whether there is a crack or incomplete fatigue. Through the setting of the backlight source, the bottom-up projection wire can enable the camera to obtain a clearer panel image to increase the visibility and facilitate the computer to identify the data in the back-end data processing. Known backlight devices, because the space available for visual inspection machines is very limited, most of the conventional techniques are to turn the backlight back on the flat plate, which can only provide the ability to project the light source, or design the backlight source to be displaced back and forth. . However, the source angle can be provided by the backlight source, and the source angle is limited to the mechanical structure. When the panel thief occurs in the panel, the solid-state backlight source device cannot make the projected light source. . In other words, if the light source is insufficient, the silky limb is uncomfortable, and the surplus (4) is low, the defective ucr of the panel with sputum is involved, which will bring about an increase in production cost and a risk of yield reduction. Therefore, how to provide the best use of the light source within a limited space can not only achieve the longitudinal and lateral displacement, but also turn to the angle, and the integrity of the crystal display panel is an important issue.

In addition to increasing visual recognition, it also avoids the risk of defective products entering the next process due to poor line of sight and poor recognition. According to an embodiment of the present invention, an adjustable backlight source device for visual inspection of a liquid crystal display panel is provided. The plurality of mechanical structures are disposed in a limited space, and includes a lateral fixing seat and a longitudinal fixing seat. And using a trimming plug disposed on one side of the longitudinal fixing seat and the lateral fixing seat, respectively providing a backlight source for longitudinal and lateral displacement adjustment. In addition, a rotating unit is used to adjust the angle of the backlight source to provide a variable angle of light for visual inspection of the liquid crystal display panel. In the following, the specific embodiments and the accompanying drawings are explained in detail, and it is easier to understand the purpose, technical content, features and functions of the present invention. [Embodiment] Hereinafter, a backlight source adjusting device for visual inspection of a liquid crystal display panel implemented by the present inventive concept will be described with reference to a preferred embodiment. Please refer to ΙΜΑ ϋ and 帛 IB si for adjusting the I side view and the bottom view for the backlight source implemented with this concept. As shown in the figure, in this embodiment, the backlight source adjusting device 1 includes a guide rod 46, a transverse fixing seat 32 and a longitudinal fixing seat 42 fixed to the guiding rod 46. In this embodiment, the longitudinal mount 42 is coupled to the lateral mount 32 by a connecting rod. Since the lateral fixing seat 32 and the longitudinal fixing seat 42 provide a limited length for displacement, the lateral fixing pin 32 and the longitudinal fixing seat 42 are laterally fine-tuned by a lateral fixing lever 30 and a longitudinal direction in a limited space. The microstrip plugs 4 提供 respectively provide a backlight source 5 6 6 M299339 row lateral displacement (lateral direction of the arrow as indicated by the first arrow 56) and a longitudinal displacement port (longitudinal displacement direction as shown by the arrow 58 in Fig. 1B) Adjustment of direction). In addition, a rotation unit 34 is provided to provide a backlight source 50 for angular adjustment, which is fixed between the longitudinal fixing seat and a fixing plate 44. Further, a fixing member (for example, a spring pin spmmg pm) is fixed as an axis of the light source 50 and a light source fixing plate 44, and the backlight source 5 is fixed to the light source fixing plate 44. When the rotating unit 34 rotates, the backlight source 5 〇 is rotated (the direction of rotation is the direction of the arrow shown by 60 in 1B®), and the angle of rotation of the backlight source 50 at this time is displayed on the scale 38. When the backlight source 5 needs to be replaced, the angle of the holder 36 #A, open, is required to rotate the rotation unit 34. In other words, after the backlight source 5 is rotated to an appropriate angle, it is also necessary to tighten the angle fixing seat 36 so that the backlight source 50 is fixed so as not to change its rotation angle due to loose mechanical structure. Referring to Fig. 2, an embodiment of a backlight source adjusting device according to an embodiment of the present invention is not intended. As shown in the figure, in this embodiment, the panel 54 to be tested is placed between the signal capturing camera 52 and the backlight source adjusting device ,, and the light source is projected through the backlight source adjusting device to provide a signal capturing camera 52. - auxiliary light for increasing visual recognition; since the signal capture camera 52 simultaneously captures the image of the panel 54 to be tested and the light source projected by the backlight source adjusting device 1, when the computer (not shown) receives the signal The image of the panel 54 to be tested transmitted by the camera 52 is sharpened to facilitate computer processing and comparison of images, and the integrity of the panel 54 to be tested is confirmed. In summary, one embodiment of the present invention provides an adjustable backlight source device for visual inspection of a liquid crystal display panel, which is provided with a plurality of mechanical structures in a limited space to provide a liquid crystal display panel for visual inspection. The light source, and the position and angle of the light source can be varied according to its plurality of mechanical structures to achieve the position of the light source and the angle of the light source which are most suitable for the panel to be tested. However, the above description is only a preferred embodiment of the present invention, and the scope of the present creation cannot be limited. That is to say, the equivalent changes and modifications made by the applicants in accordance with the scope of this patent application will remain without losing the spirit and scope of this creation, and should be regarded as a near-implementation of this creation. 7 M299339 [Simple description of the drawing] Figure 1A is a side view of the backlight source adjusting device implemented by the concept of the present invention.
