The patent document adopts an elastic probe-type conductive unit, which can effectively improve the accuracy of the conductive unit contacting the backlight source cable pin to be inspected, improve the product detection efficiency and detection effect, and reduce the outflow rate of defective products.

[0004] The above-mentioned and prior arts have the following defects: when using a jig to detect a backlight source, the backlight source needs to be placed in a placement area. Since the structure of the placement area is fixed, it is difficult to use the placement area to limit the position of the backlight source when detecting backlight sources of different sizes, thereby reducing the practicality of the jig.

[0005] Therefore, a backlight source detection jig is proposed. Utility Model Content

[0006] The utility model aims to solve the problem that it is difficult to limit the position of the backlight source by using the placement area when detecting backlight sources of different sizes due to the fixed structure of the placement area, and proposes a backlight source detection fixture.

[0027] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0029] like Figure 1-4 As shown, the utility model provides a backlight source detection jig, including a jig body 1 and a backlight source body 2 , the jig body 1 includes a limiting structure 3 , and an adjustment structure 4 is provided on the surface of the jig body 1 .

[0030] The specific settings and functions of the limiting structure 3 and the adjusting structure 4 are described in detail below.

[0031] like Figure 3 and Figure 4 As shown, the limiting structure 3 includes a slide groove 31, the slide groove 31 is opened on the surface of the fixture body 1, the inner wall of the slide groove 31 is slidably connected with a sliding frame 32, the surface of the sliding frame 32 is slidably connected with a first limiting plate 33, the surface of the fixture body 1 is fixedly connected with a second limiting plate 34, the sliding frame 32 is internally threadedly connected with a first bolt 35 and a second bolt 36, the first bolt 35 passes through the sliding frame 32 and abuts against the inner wall of the slide groove 31, the second bolt 36 passes through the sliding frame 32 and abuts against the inner wall of the first limiting plate 33, and the surface of the first limiting plate 33 is fixedly connected with the second limiting plate 34. A flexible pad 37, a second flexible pad 38 is fixedly connected to the surface of the second limit plate 34, the first flexible pad 37 and the second flexible pad 38 can prevent the backlight source from being in rigid contact with the first limit plate 33 and the second limit plate 34, causing the backlight source to be worn. Two clearance holes 39 are provided on the surface of the fixture body 1, and the clearance holes 39 are connected to the slide groove 31. When the sliding frame 32 moves along the inner wall of the slide groove 31, the sliding frame 32 will push the foreign matter that falls into the slide groove 31 to slide until the foreign matter falls out of the clearance hole 39.

[0032] like Figure 2 As shown, the adjustment structure 4 includes a support plate 41, which is rotatably connected to the fixture body 1, a pull plate 42 is slidably connected inside the support plate 41, an insertion rod 43 is slidably connected to the side wall of the support plate 41, a pull hole is opened on the surface of the pull plate 42, the size of the insertion rod 43 is matched with the size of the insertion hole 44, a roller 45 is rotatably connected to the surface of the pull plate 42, when the roller 45 slides along the surface of the workbench, the roller 45 can provide auxiliary support to the pull plate 42, and a plurality of anti-skid pads 46 are fixedly connected to the lower surface of the support plate 41, and the anti-skid pads 46 can increase the friction force on the surface of the support plate 41, thereby preventing the support plate 41 from sliding synchronously with the pull plate 42 when the pull plate 42 is pulled.

[0033] The overall working principle is as follows: before detecting the backlight source, the fixture body 1 is first placed on a workbench (not shown in the figure), and then the backlight source is placed on the surface of the fixture body 1, and at the same time, the backlight source is contacted with the second flexible pad 38, and then the sliding frame 32 is moved along the inner wall of the slide groove 31. The sliding of the sliding frame 32 will drive the first limiting plate 33 to slide. When one side of the first flexible pad 37 on the first limiting plate 33 contacts the backlight source, the first bolt 35 is rotated. After the first bolt 35 abuts against the inner wall of the slide groove 31, the first bolt 35 reaches the function of limiting the position of the sliding frame 32, and then the first limiting plate 33 is slid along the surface of the sliding frame 32 to make the other side of the first flexible pad 37 contact with the backlight source, and then the second bolt 36 is rotated. After the second bolt 36 abuts against the inner wall of the first limit plate 33, the second bolt 36 reaches the function of limiting the position of the first limit plate 33. The first limit plate 33 and the second limit plate 34 cooperate to limit the position of the backlight source, and by adjusting the position of the first limit plate 33, backlight sources of different sizes can also be limited, thereby improving the practicality of the fixture body 1. The first flexible pad 37 and the second flexible pad 38 can prevent the backlight source from being in rigid contact with the first limit plate 33 and the second limit plate 34, causing the backlight source to be worn. In the process of the sliding frame 32 moving along the inner wall of the slide groove 31, the sliding frame 32 will push the foreign matter that falls into the slide groove 31 to slide until the foreign matter falls out of the clearance hole 39.

[0034] When it is necessary to detect the backlight source from different angles, pull the insertion rod 43 upwards, pull the insertion rod 43 out of the socket 44, and then pull the pull plate 42. The pull plate 42 slides along the support plate 41 to squeeze the fixture body 1, and the fixture body 1 starts to rotate. During this process, the roller 45 slides along the surface of the workbench. The roller 45 can provide auxiliary support for the pull plate 42. After adjusting the fixture body 1 to a suitable angle, the insertion rod 43 is inserted into the corresponding socket 44 to fix the position of the fixture body 1. Therefore, by inserting the insertion rod 43 into the socket 44 at different positions, the fixture body 1 can be restricted to different angles, thereby facilitating the detection of the backlight source from different angles. The anti-slip pad 46 can increase the friction force on the surface of the support plate 41, thereby preventing the support plate 41 from sliding synchronously with the pull plate 42 when the pull plate 42 is pulled.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
