Detailed Description of the Embodiments

[0020] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the detailed description of the embodiments of the present application provided in the drawings below is not intended to limit the scope of the present application claimed, but only represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0021] An adjustable backlight detection device disclosed by the present utility model is mainly applied to the scenario where when a traditional backlight detection device is used, according to the products customized by customers, the spacing between the chamfers of each backlight is different, and corresponding kerning needs to be done according to different spacings for detection work, with cumbersome detection and long time consumption.

[0022] Referring to Figure 1 、 Figure 2 and Figure 3 An adjustable backlight detection device includes a detection board 1 and a backlight body 2. There are two chamfers 3 on one outer wall of the backlight body 2, and further includes:

[0023] An auxiliary mechanism: The auxiliary mechanism is located on both sides of the top outer wall of the detection board 1;

[0024] On one side of the top outer wall of the detection board 1, a mounting seat 4 is fixedly installed. On the top outer wall of the mounting seat 4, a connecting frame 9 is fixedly installed. A connecting shaft 10 is provided on the inner wall of the connecting frame 9. A collar is sleeved on the circumferential outer wall of the connecting shaft 10. On one outer wall of the collar, a wrench 11 is connected by a hinge. On one outer wall of the mounting seat 4, a limiting ring 15 is fixedly connected. A push rod 13 is provided on the inner wall of the limiting ring 15. One end of the push rod 13 is connected by a hinge to a connecting ring 12. The other end of the push rod 13 is fixedly connected to a push block 5. The connecting ring 12 is connected to the collar. A push groove 7 is opened on one outer wall of the detection board 1. A conductive plate 8 is provided on one inner wall of the push groove 7. The conductive plate 8 is used in cooperation with the backlight body 2.

[0025] In the specific working process, the backlight body 2 is placed on the detection board 1. The two chamfers 3 at different positions are in contact with the conductive plate 8. By pulling the wrench 11, the collar rotates on the connecting shaft 10. Under the action of the connecting ring 12, the push rod 13 moves forward, driving the push block 5 to move in the push groove 7, so that the push block 5 clamps the chamfer 3, and then the conductive plate 8 is energized to detect the backlight body 2. Clamping the chamfer 3 in contact with the conductive plate 8 by using the push block 5 enables detection regardless of whether the two chamfers 3 are close to or far from each other.

[0026] Among them, the backlight body 2 is located on the top outer wall of the detection board 1, and the chamfer 3 is in contact with the conductive plate 8. In this way, when the backlight body 2 is placed on the detection board 1 for detection, the chamfer 3 at different positions can be in contact with the conductive plate 8 for detection. The operation is simple. Positive and negative power lines (not shown in the figure) are provided inside the conductive plate 8. The conductive plate 8 is conducted through the positive and negative power lines, and the chamfer 3 of the LED lamp of the backlight body 2 is energized for detection, and the detection effect is good.

[0027] Among them, the pushing block 5 moves horizontally in the pushing groove 7. The pushing block 5 is used in cooperation with the chamfer 3. In this way, under the action of the thrust, the pushing block 5 moves horizontally in the pushing groove 7, so that the pushing block 5 clamps the chamfer 3. Due to the different positions of the chamfer 3, but all located in the pushing groove 7, the pushing block 5 can be clamped, and the linkage effect is good.

[0028] Among them, one side outer wall of the pushing block 5 is set as a rounded corner structure. In this way, when the pushing block 5 with the rounded corner structure clamps the chamfer 3, it does not wear the chamfer 3, and can be fixed stably, playing a role in protecting the chamfer 3.

[0029] Among them, the wrench 11 is used in cooperation with the push rod 13. By pulling the wrench 11, the push rod 13 moves forward. After the detection is completed, the wrench 11 is pulled back to the opposite position again, so that the push rod 13 moves backward to restore to the original position, and then the next backlight body 2 is detected, which is easy to operate.

[0030] Refer to Figure 1 and Figure 3 In a preferred embodiment, the auxiliary mechanism includes connection boxes 6 fixedly connected to both sides of the top outer wall of the detection plate 1. The top inner wall of the connection box 6 is provided with equidistantly distributed rotating shafts, and the bottom ends of the rotating shafts are provided with rollers 14.

[0031] Specifically, after the backlight body 2 is placed on the detection plate 1, during the process of the pushing block 5 clamping the chamfer 3, the backlight body 2 is prone to skew during the backward movement. The two side rollers 14 can be used to straighten the backlight body 2, and the rollers 14 cooperate with the movement during the backward movement.

[0032] Among them, the roller 14 is used in cooperation with the backlight body 2. In this way, during the rolling process of the roller 14, the backward movement of the backlight body 2 is not hindered, and the backlight body 2 can be straightened on both sides. Because the two connection boxes 6 are close to the backlight body 2, the position of the backlight body 2 can also be limited, and the cooperation effect is good.

[0033] Working principle: When in use, the backlight body 2 is placed on the detection plate 1. The positions of the two chamfers 3 are in contact with the conductive plate 8. By pulling the wrench 11, under the action of the connecting ring 12, the push rod 13 is driven to push the pushing block 5 forward to clamp the chamfer 3. While clamping, the two side rollers 14 straighten the process of the backward movement of the backlight body 2, so that it will not skew, and the rotation of the rollers 14 does not affect the movement of the backlight body 2, enabling the pushing block 5 to clamp the two chamfers 3 better at the same time. Then, the conductive plate 8 is energized, and then the detection work of the backlight body 2 is carried out.

[0034] As described above, it is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. The substitution may be the substitution of part of the structure, device, method steps, or a complete technical solution. Any equivalent substitution or change made according to the technical solution of the present utility model and its inventive concept should be covered within the protection scope of the present utility model.
