[0021] Please refer to Figures 1-4, an embodiment provided by the present utility model: An LED lamp bead encapsulation detection device, including a frame 1, a conveyor belt 2 arranged inside the frame 1 for transporting LED lamp bead components, and a photoelectric sensor 5 for detecting the position of the LED lamp bead components. The conveyor belt 2 is prior art and will not be elaborated here. The photoelectric sensor 5 can determine the presence or passage of an object by detecting the occlusion or reflection of a light beam by the object. On the outer side of the middle end of the frame 1, there is a detection fixing frame 3. On the top of the detection fixing frame 3, there is a marking mechanism for the LED lamp bead components after detection. The marking mechanism marks the unqualified lamp beads for easy later identification. Inside the hole slot on the front wall of the detection fixing frame 3, there is a movable block 32. The threaded hole inside the movable block 32 is threadedly connected to the outer side of the threaded rod 33. Both ends of the threaded rod 33 are fixed inside the hole slots at both ends of the detection fixing frame 3. The left end of the threaded rod 33 is connected to the output end of the motor 31 through a coupling. The motor 31 is installed at the left end of the detection fixing frame 3. Behind the movable block 32, there is an industrial camera 34. The motor 31 can drive the threaded rod 33 to rotate. The rotation of the threaded rod 33 will drive the movable block 32 to move inside the hole slot of the detection fixing frame 3. The movement of the movable block 32 will drive the industrial camera 34 to move together. The synchronous movement of the industrial camera 34 and the detected lamp bead components will increase the detection accuracy. Behind the industrial camera 34, there is a backlight plate 35 corresponding to it, and the horizontal midlines of the industrial camera 34 and the backlight plate 35 are at the same height. The backlight plate 35 is fixed to the inner side of the rear wall of the detection fixing frame 3. The photoelectric sensor 5 is fixed on the top of the front wall of the frame 1 and is located to the right of the hole slot of the detection fixing frame 3. On the upper and lower sides of the movable block 32, there are sliders 321. The sides of the sliders are slidably connected to the limiting slots inside the upper and lower ends of the hole slot of the detection fixing frame 3. The sliders can prevent the movable block 32 from shifting in position during movement.
[0022] The marking mechanism includes a top plate 41. The bottom of the right end of the top plate 41 is fixedly connected to the top of the detection fixing frame 3. At the top of the left end of the top plate 41, there is a hydraulic rod 42. At the bottom of the telescopic end of the hydraulic rod 42, there is a lifting plate 43. The hydraulic rod 42 can drive the lifting plate 43 to lift and lower. The top of the left end of the lifting plate 43 is fixedly connected to the bottom of the fixed tank 45. The inside of the fixed tank 45 is used to place liquid pigment. One end of the water absorption rope 46 is connected to the inside of the fixed tank 45, and one end passes through the lifting plate 43 and is connected to the inside of the marking head 44. The water absorption rope 46 can absorb the liquid inside the fixed tank 45. The marking head 44 is made of a water-absorbing sponge material. The liquid absorbed by the water absorption rope 46 will be transmitted to the inside of the marking head 44. The top of the marking head 44 is fixedly connected to the bottom of the lifting plate 43. When the marking head 44 is pressed down to the top of the LED lamp bead component, the LED lamp bead component can be dyed and marked.
[0023] Inside the top end of the fixed tank 45, there is a detachable top cover 47. The outer side of the bottom end of the detachable top cover 47 is threadedly connected to the inner side of the top end of the fixed tank 45. By rotating to open the top cover 47, it is convenient to add liquid pigment into the fixed tank 45.
[0024] During use, after the optoelectronic sensor 5 detects the position of the LED lamp bead assembly on the conveyor belt 2, the motor 31 drives the threaded rod 33 to rotate. The rotation of the threaded rod 33 drives the movable block 32 to move inside the hole slot of the detection fixed frame 3. The movement of the movable block 32 drives the industrial camera 34 to move together. The industrial camera 34 moves synchronously with the detected lamp bead assembly for shooting and detection. When the detection is unqualified, the hydraulic rod 42 can drive the lifting plate 43 to descend, and the marking head 44 presses down on the top of the LED lamp bead assembly to dye and mark the LED lamp bead assembly. The LED lamp bead assembly after dyeing and marking is convenient for observation and statistics, and also convenient for the staff to directly take out. The detection reliability is high, and the workload of the staff is reduced.
