Description

Technical Field

[0001] This invention relates to the field of LED lamp bead dispensing technology, specifically to an automatic dispensing device for arrayed LED lamp beads. Background Technology

[0002] In the processing of LED beads, LED bead boards with arrayed arrangement are produced. These products need to be glued to fix the LED beads. However, existing glue dispensing devices directly dispense glue after the LED bead boards are delivered, and then manually check whether the LED beads are working properly. This not only wastes glue and dispensing time, resulting in low dispensing efficiency, but also takes a long time for manual inspection. After working for a long time, fatigue can easily lead to misjudgment, affecting the accuracy of the inspection. Therefore, an automatic glue dispensing device for arrayed LED beads is needed. Summary of the Invention

[0003] To address the problems existing in the prior art, the purpose of this invention is to provide an automatic dispensing device for arrayed LED beads, which can save dispensing time, improve dispensing efficiency, and enhance the quality of the LED bead board.

A movable dispensing mechanism is mounted on the support frame, and two detection mechanisms are mounted on the movable dispensing mechanism. The monitoring system controls the movable dispensing mechanism and the detection mechanisms. The conveying mechanism conveys the LED bead boards to the detection mechanisms for testing. The detection mechanisms send the fault status of the LED bead boards to the monitoring system. The monitoring system controls the movable dispensing mechanism to dispense adhesive onto the LED beads that are not faulty. Finally, the detection mechanisms perform acceptance testing on the LED bead boards after dispensing.

[0005] In some embodiments, the movable dispensing mechanism includes two mounting frames, each mounting frame having an electric slider assembly, each electric slider assembly having a pneumatic actuator, and each pneumatic actuator having a mounting plate mounted on its telescopic portion.

[0006] In some embodiments, each movable frame includes two first connecting rods, which are respectively located on both sides of a mounting frame, and each first connecting rod is connected to the spring rod. A U-shaped frame is fixedly connected between the two first connecting rods. A pressing part is fixedly connected to the side of the U-shaped frame near the mounting plate, and the pressing part is located below the mounting plate. A first rack is fixedly connected to each side of the U-shaped frame, and each first rack is connected to the detection mechanism.

[0007] In some embodiments, each of the detection mechanisms includes a horizontal plate, each horizontal plate being located between two legs of a mounting frame. Each horizontal plate is provided with two detection elements. A second connecting rod is connected to each side of the mounting frame via a spring rod. An L-shaped rod is fixedly connected to each of the second connecting rods. A second rack is provided on the opposing sides of the two L-shaped rods.

[0010] In some embodiments, the conveying mechanism is a tracked conveyor, and the track of the conveying mechanism is equipped with push rods for moving the LED bead board.

[0011] In summary, the present invention has the following beneficial effects: The present invention sets up a detection mechanism on each side of the moving dispensing mechanism, which can perform detection before and after dispensing, thereby realizing the screening of LEDs for faults before and after dispensing, saving dispensing time and improving dispensing efficiency.

[0015] See Figure 1-5 An automatic dispensing device for arrayed LED beads includes a support frame 1, a conveying mechanism 2 for conveying LED bead boards 3, and a monitoring system for screening whether the LED beads are faulty. The support frame 1 is equipped with a moving dispensing mechanism 4, which is equipped with two detection mechanisms 5. The monitoring system controls the moving dispensing mechanism 4 and the detection mechanisms 5. The conveying mechanism 2 conveys the LED bead boards 3 to the detection mechanisms 5 for detection.

The monitoring system controls the moving dispensing mechanism 4 to dispense glue to the LED beads that are not faulty. Finally, the detection mechanisms 5 perform acceptance testing on the LED bead boards 3 after dispensing.

[0016] In some embodiments, the movable dispensing mechanism 4 includes two mounting brackets 41, each mounting bracket 41 is provided with an electric slider assembly 42, each electric slider assembly 42 is equipped with a pneumatic actuator 43, and each pneumatic actuator 43 is equipped with a mounting plate 44 on its telescopic part.

Both the mounting bracket 41 and the movable frame 46 are connected to the detection mechanism 5.

[0017] In some embodiments, the movable frame 46 includes two first connecting rods 461, which are located on both sides of a mounting frame 41, and each first connecting rod 461 is connected to a spring rod. A U-shaped frame 462 is fixedly connected between the two first connecting rods 461. A pressing part 463 is fixedly connected to the side of the U-shaped frame 462 near the mounting plate 44. The pressing part 463 is located below the mounting plate 44.

[0018] In some embodiments, each detection mechanism 5 includes a horizontal plate 51, each horizontal plate 51 being located between two legs of a mounting frame 41. Each horizontal plate 51 is provided with two detection elements 52. A second connecting rod 53 is connected to each side of the mounting frame 41 via a spring rod. An L-shaped rod 54 is fixedly connected to each of the two second connecting rods 53. A second rack 55 is provided on each of the opposing sides of the two L-shaped rods 54. A gear 56 is rotatably connected to each side of the mounting frame 41 via a connecting shaft. Each gear 56 is connected to a movable dispensing mechanism 4 and a second rack 55, respectively.

A camera 58 is installed on each of the two detection elements 52 on the horizontal plate 51. In some embodiments, each detection element 52 includes a detection power supply 521, which has a positive terminal 522 and a negative terminal 523. Both the positive terminal 522 and the negative terminal 523 are connected to a conductive wire 524, and the ends of the conductive wires 524 are connected to probes 525. Transparent lamp covers 526 are provided on the two probes 525.

[0019] Working principle: During use, the operator places the LED bead board 3 on the conveying mechanism 2 for transport. When the LED bead board 3 is transported to the moving dispensing mechanism 4, as shown in the attached... Figure 2As shown, the operator controls the moving dispensing mechanism 4 to drive the detection mechanism 5 located on the right side. Specifically, the air push rod 43 on the right side extends and pushes the pressing part 463 of the U-shaped frame 462 in the detection mechanism 5 on the right side to move downward. Then, the pressing part 463 drives the two first racks 464 to move downward. Taking one side as an example, as shown in the attached diagram... Figure 5 As shown, the first rack 464 drives the gear 56 to rotate, which in turn drives the L-shaped rod 54 to move upward. The U-shaped rod 57 drives multiple transparent lamp covers 526 to move upward, allowing the LED beads on the LED bead board 3 to enter the coverage area of ​​the multiple transparent lamp covers 526. Then, the operator controls the pneumatic push rod 43 to retract and reset. Then, the moving frame 46 resets under the action of the spring rods of the two first connecting rods 461. At the same time, the second connecting rods 53 on the two L-shaped rods 54 also reset under the action of the spring rods, so that the multiple transparent lamp covers 526 cover the LED beads on the LED bead board 3, and the positive terminal of the detection power supply 521 is detected. Terminal 522 and negative terminal 523 are connected to the positive and negative terminals of the LED beads on the LED bead board 3 respectively via probe 525, thereby connecting the LED bead circuit. If the LED bead lights up, it means that the LED bead connection is normal. If the LED bead does not light up, it means that the LED bead connection is abnormal. The power supply detection 521 can be a multimeter. The detection principle is the same as the detection principle of using a multimeter, which will not be elaborated here. At this time, the camera 58 will upload the lighting status of the LED beads to the remote terminal. The remote terminal records which LED beads are normally connected and which LED beads are abnormally connected. The remote terminal then controls the moving dispensing mechanism 4 to dispense glue, realizing the detection of the LED bead status before dispensing. After checking the LED bead status before dispensing, the operator controls the pneumatic actuator 43 to extend, causing the dispensing component 45 to move downwards. During this movement, the transparent lampshade 526 is first moved upwards to no longer cover the LED bead. Then, the conveying mechanism 2 moves the LED bead directly below the dispensing component 45, as shown in the attached diagram. Figure 2 As shown, the operator then controls the pneumatic actuator 43 to move the dispensing component 45 downwards to cover a light bead and dispense glue. The dispensing component 45 is an existing intelligent dispensing device that dispenses glue according to instructions from the remote terminal. Details are omitted here. After dispensing one light bead, the pneumatic actuator 43 moves the dispensing component 45 upwards above the height of the light bead. Then, the electric slider assembly 42, controlled by the remote terminal, moves the pneumatic actuator 43 to the position of the normally connected light bead. The pneumatic actuator 43 then controls the dispensing component 45 to move downwards to dispense glue. This completes the dispensing of one row of light beads. At this time, the next row of light beads has also completed its status check. After the dispensing component 45 is reset by the pneumatic actuator 43, the next row of light beads is then transported to the area below the dispensing component 45. The above actions are repeated to complete the dispensing process. After a row of LED beads completes the dispensing process, as the next row moves below the dispensing component 45, the row of LED beads that has completed dispensing moves to the detection mechanism 5 located to the left of the dispensing component 45. Therefore, during the dispensing of a row of LED beads, the row of LED beads to the right of that row that has not yet been dispensed undergoes a status check before dispensing, while the row of LED beads to the left of that row that has completed dispensing undergoes a status check after dispensing. The detection principle is the same as the status check before dispensing. The lighting status of the LED beads is recorded by the camera 58. If the LED bead lights up, it means that the dispensing is normal and the LED bead has not been damaged by the dispensing. If the LED does not light up, it means that the LED bead was damaged after dispensing. This completes the screening of the LED beads, which facilitates subsequent directional replacement and ensures the quality of the LED bead board 3.

[0020] In some embodiments, the detection power supply 521 is a rechargeable power supply. This allows operators to easily charge the detection power supply 521 at any time, ensuring that the detection power supply 521 is always in a working state.

[0021] In some embodiments, aluminum foil is adhered to the lower half of the inner side of the transparent lampshade 526. This can block the light from the lower half of the transparent lampshade 526, preventing the light from the lamp beads after they are lit from passing through the transparent lampshade 526 and affecting the state of the lamp beads inside the surrounding transparent lampshade 526, thus preventing the camera 58 from misjudging the situation.

[0022] In some embodiments, the conveying mechanism 2 is a tracked conveyor, and push rods for moving the LED bead board 3 are mounted on the track of the conveying mechanism 2. The tracked conveyor can smoothly move the LED bead board 3, which is prior art and will not be described in detail here.

[0023] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
