As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0033] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0034] Example 1: Figure 1-Figure 6 As shown, a position detection device for a matrix light-emitting component includes a frame 1 and a gantry 4 fixed to the top outer wall of the frame 1 by bolts, a conveying mechanism 2 for conveying the light-emitting component is arranged on the inner side of the frame 1, and a detection mechanism 3 for collecting images of the light-emitting component is arranged on the inner side of the gantry 4.

[0035] The detection mechanism 3 includes an isolation cover 7, an image acquisition camera 8 fixed to the inner wall of the isolation cover 7, and a fill light 9 fixed to the inner wall of the isolation cover 7 and surrounding the image acquisition camera 8. The top of the isolation cover 7 is slidably connected to a lifting plate 11 through a "T"-shaped guide rod 6, and the lifting plate 11 is slidably connected to the inner side of the gantry 4. The top outer wall of the gantry 4 is fixed with a telescope 5 by bolts, and the telescopic end of the telescope 5 is fixed to the top of the lifting plate 11 by bolts.

[0036] The image acquisition camera 8 is electrically connected to an image processing device, which is used to compare the image captured by the image acquisition camera 8 to determine the position of the matrix light emitting component. The specific comparison method can adopt the following steps:

[0037] S1: The image acquisition camera 8 transmits the acquired image to the image processing device;

[0038] S2: Inputting the image of the position standard into the image processing device in advance;

[0039] S3: The image processing device compares the acquired image with the pre-input image for similarity;

[0040] S4: A similarity threshold is set, and images with a similarity greater than the threshold are judged as qualified, otherwise they are judged as unqualified.

[0041] This device, by setting up an isolation cover 7 and a fill light 9, the isolation cover 7 can isolate external light, and then use the fill light 9 for fill light, so that the intensity of light can be completely controlled by the fill light 9, so that it can be within the brightness range of reliable image capture by the image acquisition camera 8, increase the clarity of image capture, and thus increase the accuracy of subsequent image processing and position judgment.

[0042] In this embodiment, an on / off control component 10 for controlling the shooting timing of the image acquisition camera 8 and the start / stop timing of the fill light 9 is disposed on the outer side of one of the “T”-shaped guide rods 6 .

[0043] The opening and closing control component 10 includes a group of mutually cooperating electrode sheets 14 and a group of mutually cooperating electrode sheets 15. The outer wall of the "T"-shaped guide rod 6 is slidably connected with a ring 12, and the bottom of the ring 12 is connected to the outer wall of the isolation cover 7 through a spring 13.

[0044] One of the electrode sheets 14 is fixed to the top outer wall of the isolation cover 7 , and the other electrode sheet 14 is fixed to the bottom outer wall of the sleeve ring 12 , and the two electrode sheets 14 are connected in series to the shutter circuit of the image acquisition camera 8 .

[0045] One of the electrode sheets 15 is fixed to the top outer wall of the ring 12 , and the other electrode sheet 15 is fixed to the bottom outer wall of the lifting plate 11 , and the two electrode sheets 15 are connected in series to the power supply circuit of the fill light 9 .

[0046] The device, by setting up an on-off control component 10, realizes the on-off control of the image acquisition camera 8 and the fill light 9 through a simple mechanical mechanism, so the cost is low. At the same time, by utilizing an ingenious secondary motion structure, fill light is performed first, then shooting, and finally resetting, thereby preventing insufficient clarity caused by shooting before fill light, thereby increasing reliability.

[0047] In this embodiment: after the conveying mechanism 2 conveys the matrix light-emitting component to the bottom of the isolation cover 7, the telescope 5 extends, so that the lifting plate 11 and the isolation cover 7 descend, until the isolation cover 7 descends to contact with the conveying mechanism 2, and the isolation cover 7 cooperates with the conveying mechanism 2 to form a relatively closed environment. At this time, the telescope 5 continues to extend, the lifting plate 11 descends, and the two electrode sheets 15 first contact, so that the power supply circuit of the fill light 9 is connected, and the fill light 9 starts to fill light. Then, when the lifting plate 11 continues to descend, the lifting plate 11 will apply pressure to the ring 12 through the electrode sheet 15, so that the ring 12 overcomes the elastic force of the spring 13 and descends until the two electrode sheets 14 contact, and the shutter circuit of the image acquisition camera 8 is turned on, and the image acquisition camera 8 takes pictures and then resets.

[0048] Embodiment 2: A position detection device for a matrix light emitting component. This embodiment makes the following improvements on the basis of embodiment 1: Figure 1-Figure 6 As shown, the conveying mechanism 2 includes a conveying assembly 16 arranged at the bottom of the inner side of the frame 1 and a plurality of groups of bearing assemblies 18 arranged at the inner side of the frame 1 and arranged in a ring along the conveying assembly 16 . The bearing assemblies 18 are movably limited and engaged with the inner side of the frame 1 through guide grooves 17 .

[0049] The supporting assembly 18 includes a supporting plate 19 and sliders 24 symmetrically slidably connected to the inner walls of both sides of the supporting plate 19, and a positioning finger 25 for correcting the position of the light-emitting assembly is fixed on the top of the slider 24. The supporting plate 19 is limited and matched with the inner wall of the guide groove 17 through the limiting rollers 20 rotatably connected on both sides.

[0050] The side wall of the slider 24 is slidably connected with an arc rod 22, the inner end surface of the arc rod 22 is connected to one side wall of the slider 24 through a spring 23, and the other side of the slider 24 is connected to the inner wall of the bearing plate 19 through a spring 3 26.

[0051] A pair of arc-shaped limit blocks 21 cooperating with the arc rods 22 are fixed to the inner side wall of the frame 1 located upstream of the detection mechanism 3 .

[0052] The light-emitting component can be placed above the supporting plate 19. When the supporting plate 19 moves for transportation, until the arc head rod 22 moves to cooperate with the arc limit block 21, the arc head rod 22 is pushed inward by the limit of the arc limit block 21, and the slider 24 can be moved inward by the spring 23, so that the light-emitting component is placed in the middle position through the positioning finger 25.

[0053] The device, by setting up structures such as the arc head rod 22, the slider 24, and the alignment finger 25, can, on the one hand, utilize the movement of the alignment finger 25 to place the light-emitting component in the middle position, thereby facilitating the subsequent photo positioning and reducing the size of the photo for image processing; on the other hand, the arc head rod 22 and the slider 24 transmit the force through the spring 23, thereby preventing the light-emitting component from being squeezed and damaged. At the same time, the power for straightening comes from the limitation of the arc head rod 22 by the arc limit block 21, saving the power source and the setting of the control algorithm.

[0054] In this embodiment, the specific form of the conveying component 16 is not limited, and it can be a belt transmission mechanism or a chain transmission mechanism. This embodiment is preferably a belt transmission mechanism, and the outer wall of the transmission belt of the conveying component 16 is connected to the inner wall of the supporting plate 19 through a connecting rope 27.

[0055] When the conveying assembly 16 is started, it can pull the carrying plate 19 through the connecting rope 27 , so that the carrying plate 19 moves along the path of the guide groove 17 through the cooperation between the limiting roller 20 and the guide groove 17 .

[0056] In this embodiment: the light-emitting component can be placed above the carrier plate 19. When the conveying component 16 is started, it can pull the carrier plate 19 through the connecting rope 27, so that the carrier plate 19 moves along the path of the guide groove 17 through the cooperation of the limiting roller 20 and the guide groove 17. When the carrier plate 19 moves for transportation, until the arc head rod 22 moves to cooperate with the arc limit block 21, the arc head rod 22 is pushed inwardly through the limitation of the arc limit block 21, and the slider 24 can be moved inwardly through the spring 23, so that the light-emitting component is placed in the middle position through the positioning finger 25.

[0057] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
