Description

Technical Field

[0001] The utility model relates to the technical field of LED detection, in particular to a detection platform for a pre-injection-molded LED substrate. Background Art

[0002] With the rapid development of LED lighting technology, pre-molded LED substrates, as core components of LED lamps, are becoming increasingly important. Their quality and performance stability are crucial to the overall performance of the lighting system. To ensure the production quality of pre-molded LED substrates, visual inspection is required during production.

[0003] Current inspection platforms typically utilize automated conveyor belts and visual inspection mechanisms (industrial cameras) for automated inspection. However, since substrate inspection typically involves both the top and bottom surfaces, current inspection platforms first inspect one side of the substrate, then flip it over and inspect the bottom surface. This approach requires manual flipping of the substrate before inspection, which wastes significant inspection time and significantly reduces production inspection efficiency. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings in the prior art and to propose a detection platform for pre-injection-molded LED substrates.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions:

[0006] A detection platform for pre-injection molded LED substrates, comprising a first conveyor belt, a second conveyor belt, an industrial computer, and a visual inspection mechanism. The second conveyor belt is arranged at the rear end of the first conveyor belt, and the industrial computer is installed on the side of the first conveyor belt. Both the first and second conveyor belts are installed with portal frames, and the inner top walls of the two portal frames are installed with visual inspection mechanisms.

[0007] A feeding guide assembly is provided at the head end of the conveyor belt 1, and a feeding turning mechanism is provided between the conveyor belt 1 and the conveyor belt 2.

[0008] As a further description of the above technical solution: the loading guide assembly includes two mounting plates fixedly mounted on both sides of a conveyor belt frame, the opposite sides of the two mounting plates are fixedly mounted with electric telescopic rods, and the ends of the two electric telescopic rods away from the mounting plates are fixedly connected to arc-shaped guide plates through connecting frames.

[0009] As a further description of the above technical solution: the feeding and flipping mechanism includes a U-shaped bracket, the upper rotation of the U-shaped bracket is connected to a rotating shaft, the front side of the U-shaped bracket is fixedly installed with a flipping motor, the output shaft of the flipping motor is fixedly connected to the rotating shaft, and the surface of the rotating shaft is axially equidistantly connected with a plurality of flip plates.

[0010] As a further description of the above technical solution: the two arc-shaped guide plates are arranged in an "eight" shape and the feeding end close to the conveyor belt is larger, and a plurality of guide shafts are rotatably connected to the arc-shaped guide plates.

[0011] As a further description of the above technical solution: light sources are provided on the inner top wall of the portal frame and on both sides of the visual detection mechanism.

[0012] As a further description of the above technical solution: a discharge platform is provided on the side of the second conveyor belt near the tail end, and a push plate is provided on the second conveyor belt corresponding to the discharge platform. An electric push rod is fixedly connected to the outer side of the push plate, and a mounting frame is fixedly connected to the side of the electric push rod away from the push plate, and the mounting frame is fixedly connected to the frame of the second conveyor belt.

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] 1. This solution sets up two conveyor belts and uses a loading and flipping mechanism to flip the pre-injected LED substrate to be tested 180° from one conveyor belt to the other. The surface and inside of the substrate are inspected by a visual inspection mechanism on both conveyor belts. This arrangement can achieve continuous inspection of the substrate, greatly improving production efficiency and product quality, and meeting the modern LED lighting industry's demand for high-quality and high-efficiency production.

[0015] Second, this solution adds a loading guide component to conveyor belt one to guide the substrate into the inspection area, ensuring that the conveying route of the pre-injected LED substrate to be tested corresponds to the visual inspection mechanism, thereby ensuring the inspection effect; in addition, a discharge table and a pusher component are added to the tail end of conveyor belt two to automatically sort out unqualified substrates for inspection, further improving work efficiency.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] See also Figure 1 A pre-molded LED substrate inspection platform includes a conveyor belt 1, a conveyor belt 2, an industrial computer 3, and a visual inspection mechanism 4. The industrial computer 3 is used to control the entire inspection process and process inspection data. The visual inspection mechanism 4 is typically an industrial camera. The industrial camera takes a picture of the pre-molded LED substrate and transmits it to the industrial computer 3. The program algorithm in the industrial computer 3 performs image recognition and automatically inspects the substrate.

[0023] Conveyor belt 2 2 is arranged at the tail end of conveyor belt 1 1, and the industrial computer 3 is installed on the side of conveyor belt 1 1. Door frames 5 are installed on both conveyor belt 1 1 and conveyor belt 2 2, and visual inspection mechanisms 4 are installed on the inner top walls of the two door frames 5; a loading and turning mechanism 7 is arranged between conveyor belt 1 and conveyor belt 2 2.

[0024] The above structure: During inspection, the pre-injected LED substrates to be tested are simply placed one by one on conveyor belt 1. The visual inspection mechanism 4 on conveyor belt 1 inspects the substrate surface. After inspection, the substrate is flipped 180 degrees by the loading and unloading mechanism 7 and moved to conveyor belt 2 2. Conveyor belt 2 continues to feed the substrate. When the substrate moves below the visual inspection mechanism 4, the visual inspection mechanism 4 on conveyor belt 2 inspects the substrate bottom surface. This solution enables continuous inspection of substrates, with high work efficiency.

[0025] Specifically, such as Figure 3 As shown, the loading and flipping mechanism 7 includes a U-shaped bracket 71, the upper rotation of the U-shaped bracket 71 is connected to the rotating shaft 72, the front side of the U-shaped bracket 71 is fixedly installed with a flip motor 73, the output shaft of the flip motor 73 is fixedly connected to the rotating shaft 72, and the surface of the rotating shaft 72 is axially equidistantly connected with multiple flip plates 74.

[0026] Conveyor belt 1 will transport the pre-injected LED substrate and send it between the two flip plates 74. At the same time, the flip motor 73 will drive the rotating shaft 72 and the flip plate 74 to rotate, so that the substrate stuck between the two flip plates 74 will be flipped 180° along with the loading flip mechanism 7 (at this time the bottom surface of the substrate faces up and the surface faces down) and moved to conveyor belt 2 2. Under the action of conveyor belt 2 2, the substrate with the bottom surface facing up will be transported to facilitate subsequent inspection.

[0027] In addition, light sources 8 are provided on the inner top wall of the portal frame 5 and on both sides of the visual inspection mechanism 4 for lighting, preventing shadow interference and ensuring the inspection effect.

[0028] Example 2

[0029] Based on the above embodiment, in order to ensure that the substrate is aligned with the visual inspection mechanism 4 during inspection, a loading guide assembly 6 is provided at the head end of the conveyor belt 1, and the loading guide assembly 6 is used to assist in conveying and guiding the substrate.

[0030] The loading guide assembly 6 comprises two mounting plates 61 fixedly mounted on either side of the conveyor frame 1. Electric telescopic rods 62 are fixedly mounted on opposite sides of the mounting plates 61. The ends of the two electric telescopic rods 62, away from the mounting plates 61, are fixedly connected to curved guide plates 63 via connecting brackets. The distance between the two curved guide plates 63 is adjusted by the electric telescopic rods 62 to accommodate the guidance of substrates of different sizes.

[0031] The two arc-shaped guide plates 63 are arranged in an "eight" shape and have a larger opening near the feeding end of the conveyor belt 1, which is convenient for loading. Multiple guide shafts 64 are rotatably connected to the arc-shaped guide plates 63 to reduce friction on the side of the substrate.

[0032] Example 3

[0033] Based on the above embodiment, a discharge platform 9 is provided on the side of the conveyor belt 2 2 near the tail end, and a push plate 10 is provided on the conveyor belt 2 2 corresponding to the discharge platform 9. An electric push rod 11 is fixedly connected to the outer side of the push plate 10, and a mounting frame 12 is fixedly connected to the side of the electric push rod 11 away from the push plate 10. The mounting frame 12 is fixedly connected to the frame of the conveyor belt 2 2.

[0034] When an unqualified substrate is detected, the electric push rod 11 extends and drives the push plate 10 to move toward the discharge table 9, pushing the unqualified substrate from the conveyor belt 2 2 to the discharge table 9, and the qualified substrate continues to be transported to the next process, thereby realizing automated sorting.

[0035] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
