[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] Example

[0030] Refer to the attached drawings of the specification, such as Figure 1-Figure 7 As shown, a backlight source detection device detects the backlight source through a detector. Specifically, the detection device includes a first fixing device 1 and a second fixing device 2 arranged relative to the first fixing device 1. The backlight source is placed on the first fixing device 1; and the detector is placed on the second fixing device 2.

[0031] like Figure 2 , Figure 3As shown, the first fixing device 1 includes a rotating wheel 11, a rotating shaft 12 and a support 13. The rotating wheel 13 rotates synchronously with the rotating shaft 12, and the rotating shaft 12 is inserted into the support 13, and the rotating shaft 12 and the support 13 rotate in steps. Specifically, a bearing can be provided at the connection between the rotating shaft 12 and the support 13. A plurality of mounting frames 14 are distributed circumferentially on the rotating wheel 11, and the backlight source is fixedly connected to the mounting frame 14. When the rotating shaft 12 drives the rotating wheel 11 to rotate, the mounting frame 14 rotates with the rotating wheel 11, so the position of the backlight source in the mounting frame 14 changes and reaches the lowest point of the rotating wheel 11. When the backlight source to be detected is at the lowest point of the rotating wheel 11, the position of the detector on the second fixing device 2 corresponds to the position of the backlight source, so that the light emitted by the backlight source is received and detected. Since each backlight source can reach the lowest point of the wheel 11 by rotating during the rotation of the wheel 11, each backlight source on the wheel 11 can be detected by the detector. During this process, there is no need to adjust the detector or replace multiple backlight sources one by one, thereby ensuring the efficiency and accuracy of the detection.

[0032] Specifically, Figure 7 As shown, the mounting frame 14 includes a connecting plate 141 and a accommodating frame 142 fixedly connected to the connecting plate 141. Among them, the connecting plate 141 is connected to the rotating wheel 11; one side of the accommodating frame 142 is an opening, and the backlight source can be placed in the accommodating frame 142 through the opening. Optionally, the accommodating frame 142 can be a box body spliced ​​by multiple boards, or a square frame spliced ​​by multiple profiles. The size of the accommodating frame 142 depends on the size of the backlight source to be detected, so as to ensure that the backlight source can be placed in the accommodating frame 142 while preventing the backlight source from loosening after being placed in the accommodating frame 142. Further, a plurality of first blocks 143 are arranged on the edge of one side of the opening of the accommodating frame 142, and the shape of the first block 143 is "L" shaped, and its two sides are respectively fixed to the two sides of the accommodating frame 142 that are perpendicular to each other. The material of the first block 143 can be selected from one of silica gel, foam or sponge. When installing the backlight source, the backlight source can be inserted into the interior of the accommodating frame 142 from the opening side of the accommodating frame 142. Optionally, the first stopper 143 and the backlight source can be fixed in the accommodating frame 142 by bonding.

[0033] like Figure 4-Figure 7As shown, a plurality of fixed shafts 15 are distributed circumferentially on the rotating wheel 11, and a circular hole 144 is provided on the top of the connecting plate 141 correspondingly, and the fixed shaft 15 passes through the circular hole 144 and the rotating wheel 11 in sequence, so that the mounting frame 14 is installed on the rotating wheel 11. Optionally, the diameter of the circular hole 144 on the connecting plate 141 is larger than the diameter of the fixed shaft 15, so that the connecting plate 141 and the fixed shaft 15 rotate in steps. During the rotation of the rotating wheel 11, the mounting frame 14 does not rotate with the rotating wheel 11, so that the mounting frame 14 is always vertically downward, and the backlight source located inside the mounting frame 14 is not easy to change, thereby ensuring the accuracy of the detection.

[0034] Second stops 151 are provided at both ends of the fixed shaft 15, so that the position of the connecting plate 141 is limited between the second stops 151 and the rotating wheel 11. Optionally, the second stop 151 at one end is fixedly connected to the fixed shaft 15, and the stop 151 at the other end can be connected to the fixed shaft 15 by threads, so that the fixed shaft 15 can be detachably connected to the rotating wheel 11.

[0035] Further, such as Figure 3 , Figure 4 As shown, the shape of the rotating wheel 11 is a circular ring, which is divided into an outer ring 111 and an inner ring 112, and the fixed shaft 15 is arranged between the outer ring 111 and the inner ring 112. A boss 113 is arranged in the center of the inner ring 112, and the rotating shaft 12 is passed through the center of the boss 113. Specifically, the rotating shaft 12 and the boss 113 can be connected by a key. A plurality of support rods 114 are arranged between the boss 113 and the inner ring 112, so that the rotating wheel 11 is hollowed out to reduce the overall weight of the rotating wheel 11.

[0036] like Figure 1 As shown, the second fixing device 2 is provided with a telescopic rod 21, and the detector used for detection can be fixed to the top of the telescopic rod 21 by welding. The telescopic rod 21 can be extended and retracted by pneumatic or hydraulic means to achieve vertical movement. By providing the telescopic rod 21, the height of the detector can be appropriately adjusted.

[0037] In addition, the rotation of the rotating shaft 12 is driven by the motor 3. A base 4 is arranged at the bottom of the first fixing device 1 and the second fixing device 2.

[0038] Based on the above structure, this application has the following advantages:

[0039] 1. Multiple backlight sources are circumferentially installed on the rotating wheel 11. During the rotation of the rotating wheel 11, the position of the backlight source changes, and the backlight source located at the bottom of the rotating wheel 11 can be detected by the detector, thereby realizing rotation detection between multiple different backlight sources. During this process, there is no need to replace the backlight source, thereby ensuring the efficiency of the detection and the accuracy of the detection results.

[0040] 2. The mounting frame 14 on which the backlight source is placed rotates in steps with the rotating wheel 11, so that during the rotation of the rotating wheel 11, the mounting frame 14 is always positioned vertically downward to prevent the backlight source inside the mounting frame 14 from rotating with the rotating wheel 11 and causing changes in position or angle, thereby ensuring the detection.

[0041] 3. The second fixing device 2 is provided with a telescopic rod 21 , which can move in the vertical direction by telescoping, so as to adjust the height of the detector to match the position height of the backlight source on the first fixing device 1 .

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
