Description

An AOI inspection device for LED beads Technical Field

[0001] This utility model belongs to the technical field of AOI inspection equipment, and specifically relates to an AOI inspection device for LED beads. Background Technology

[0002] AOI is a new type of automated optical inspection method. It is a device based on optical principles that detects common defects in products. Its principle is to take pictures of the product with an industrial camera to collect images, and then detect the defects by comparing them with qualified products and marking them on the images.

[0003] In the LED chip manufacturing process, the plate-shaped semi-finished products (such as COB packages or high-density LED array substrates) that have been cured with adhesive need to be cut into independent units, and then AOI (automated optical inspection) is performed to identify surface defects (such as bubbles, scratches, and lead adhesion). However, the existing technology adopts a step-by-step approach to cutting and AOI inspection. The cut individual chips need to be repositioned and transferred to the AOI equipment, which increases the time spent on inter-process connections. Summary of the Invention

[0004] In view of the problem that the existing technology adopts the step-by-step execution mode of cutting and AOI inspection, and the cut individual lamp beads need to be repositioned and transferred to the AOI equipment, resulting in increased time consumption between processes, this utility model proposes an AOI inspection device for lamp beads to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an AOI (Automated Optical Inspection) device for LED beads, comprising a conveying assembly, a placement seat and a cutting assembly on the outer surface of the conveying assembly, a linkage assembly and a telescopic assembly inside the placement seat, a detector fixedly mounted on the top of the conveying assembly, the conveying assembly for moving the placement seat, the cutting assembly for cutting the LED bead substrate on the top of the placement seat, the cutting assembly for moving the telescopic assembly through the linkage assembly, and the telescopic assembly for ejecting the LED bead.

[0007] Furthermore, the conveying assembly includes a support plate, a mounting frame is fixedly mounted on the outer surface of the support plate, a motor is fixedly mounted on the outer surface of the mounting frame, a conveyor chain plate is provided on the outer surface of the support plate, the output shaft of the motor is drivenly connected to the conveyor chain plate, and the placement seat is fixedly mounted on the outer surface of the conveyor chain plate.

[0008] Furthermore, the cutting assembly includes a bracket, which is fixedly installed on the top of the support plate. An electric push rod is fixedly installed on the outer surface of the bracket. A square plate is fixedly installed on the movable end of the electric push rod. A die-cutting seat and a push rod are fixedly connected to the bottom of the square plate.

[0009] Furthermore, the linkage component includes a sliding frame that is slidably connected to the placement seat. A first rack is fixedly connected to the outer surface of the sliding frame, a gear meshes with the outer surface of the first rack, a rotating shaft is fixedly connected to the outer surface of the gear, the rotating shaft is rotatably connected inside the placement seat, and a second rack meshes with the outer surface of the gear.

[0010] Furthermore, the telescopic assembly includes a fixed cylinder, a spring fixedly connected inside the fixed cylinder, a limit plate fixedly connected to the upper end of the spring, a sliding rod fixedly connected to the top of the limit plate, a sliding plate fixedly connected to the top of the sliding rod, a sliding seat fixedly connected to the top of the sliding plate, the fixed cylinder fixedly connected inside the placement seat, the limit plate and the sliding rod both slidably connected inside the fixed cylinder, the sliding seat slidably connected to the placement seat, and the sliding plate fixedly connected to the second rack.

[0011] Furthermore, the outer surface of the mounting bracket is threaded with bolts, and the mounting bracket is fixedly mounted on the outer surface of the support plate by bolts.

[0012] Furthermore, a support leg is fixedly connected to the bottom of the support plate.

[0013] This utility model has the following beneficial effects:

[0014] This invention connects a conveying component and a cutting component. The conveying component moves the placement seat and the plate-shaped semi-finished product, allowing them to move to a position below the cutting component for cutting. After the LED bead is cut off from the plate-shaped semi-finished product, it falls into the placement seat. The conveying component then continues to move the placement seat and the LED bead to a position below the detector for detection. This eliminates the need for repositioning and long-distance transport, reducing the time spent on connecting processes.

[0015] This invention utilizes the connection between the second rack and the sliding plate. When the electric push rod pushes the sliding frame and the first rack downwards, the first rack drives the sliding plate upwards via the gear and the second rack, causing the sliding plate to move the sliding seat upwards. At this time, the sliding seat can support the plate-shaped semi-finished product, facilitating cutting. After cutting, the electric push rod drives the push rod to separate from the sliding frame. At this time, the spring pulls the sliding plate and the sliding seat to reset, allowing the cut LED beads to fall between the placement seat and the sliding seat, preventing the LED beads from sliding from the top of the placement seat to the ground.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0029] Please refer to Figures 1-7. This utility model is an AOI inspection device for LED beads, including a conveying component 1. The outer surface of the conveying component 1 is provided with a placement seat 2 and a cutting component 3. The interior of the placement seat 2 is provided with a linkage component 4 and a telescopic component 5. A detector 6 is fixedly installed on the top of the conveying component 1. The conveying component 1 is used to drive the placement seat 2 to move. The cutting component 3 is used to cut the LED bead substrate on the top of the placement seat 2. The cutting component 3 pushes the telescopic component 5 to move through the linkage component 4. The telescopic component 5 is used to eject the LED bead.

[0030] The plate-shaped semi-finished product (such as COB packaging or high-density LED array substrate) that has been cured by dispensing is placed on top of the placement seat 2. The conveying component 1 is activated to move the placement seat 2, so that the placement seat 2 moves the plate-shaped semi-finished product under the cutting component 3. The cutting component 3 is then activated to descend and cut the plate-shaped semi-finished product on top of the placement seat 2. During the descent, the cutting component 3 moves the telescopic component 5 through the linkage component 4, so that the telescopic component 5 slides upward within the placement seat 2 to support the plate-shaped semi-finished product and facilitate cutting. After cutting, the LED beads fall into the placement seat 2. The conveying component 1 continues to move the placement seat 2 and the LED beads to below the detector 6. The LED light source in the detector 6 illuminates the LED beads, and the reflected light signal is captured by a high-resolution industrial camera to generate a digital image. After comparison with a standard template by an algorithm, defects are identified.

[0031] This invention connects the conveying component 1 and the cutting component 3. The conveying component 1 moves the placement seat 2 and the plate-shaped semi-finished product, so that the placement seat 2 and the plate-shaped semi-finished product are moved to the under of the cutting component 3 for cutting. After the lamp bead is cut off from the plate-shaped semi-finished product, the lamp bead falls into the placement seat 2. The conveying component 1 continues to move the placement seat 2 and the lamp bead to the under of the detector 6 for detection. There is no need for repositioning and long-distance transportation, which reduces the time spent on connecting processes.

[0032] In one embodiment, the conveying assembly 1 includes a support plate 101, a mounting frame 102 is fixedly mounted on the outer surface of the support plate 101, a motor 103 is fixedly mounted on the outer surface of the mounting frame 102, a conveying chain plate 104 is provided on the outer surface of the support plate 101, the output shaft of the motor 103 is connected to the conveying chain plate 104, and the placement seat 2 is fixedly mounted on the outer surface of the conveying chain plate 104.

[0033] When motor 103 is started, its output shaft drives the rollers of conveyor chain plate 104 to rotate, causing conveyor chain plate 104 to rotate. At this time, conveyor chain plate 104 can move the placement seat 2 and the plate-shaped semi-finished product. Mounting frame 102 provides a fixed position for motor 103 to be installed, so that motor 103 remains stable during operation.

[0034] In one embodiment, the cutting assembly 3 includes a bracket 301, which is fixedly installed on the top of the support plate 101. An electric push rod 302 is fixedly installed on the outer surface of the bracket 301. A square plate 303 is fixedly installed on the movable end of the electric push rod 302. A die-cutting seat 304 and a push rod 305 are fixedly connected to the bottom of the square plate 303.

[0035] When the conveyor chain plate 104 moves the placement seat 2 and the plate-shaped semi-finished product to below the bracket 301, the electric push rod 302 on the bracket 301 is activated. The movable end of the electric push rod 302 pushes the square plate 303 down. The square plate 303 drives the die-cutting seat 304 to move down, so that the die-cutting seat 304 is inserted into the placement seat 2. During the insertion process, the die-cutting seat 304 can cut the plate-shaped semi-finished product on the top of the placement seat 2. The lamp beads cut from the surface of the plate-shaped semi-finished product fall into the placement seat 2.

[0036] In one embodiment, the linkage component 4 includes a sliding frame 401, which is slidably connected to the placement seat 2. A first rack 402 is fixedly connected to the outer surface of the sliding frame 401. A gear 403 meshes with the outer surface of the first rack 402. A rotating shaft 404 is fixedly connected to the outer surface of the gear 403. The rotating shaft 404 is rotatably connected inside the placement seat 2. A second rack 405 meshes with the outer surface of the gear 403.

[0037] The square plate 303 drives the push rod 305 to descend, and the push rod 305 pushes the sliding frame 401 and the first rack 402 to move downward. The first rack 402 drives the gear 403 and the rotating shaft 404 to rotate. The gear 403 meshes with the second rack 405, which can drive the second rack 405 to move. At this time, the first rack 402 and the second rack 405 move in opposite directions.

[0038] In one embodiment, the telescopic assembly 5 includes a fixed cylinder 501, a spring 502 fixedly connected inside the fixed cylinder 501, a limiting plate 503 fixedly connected to the upper end of the spring 502, a sliding rod 504 fixedly connected to the top of the limiting plate 503, a sliding plate 505 fixedly connected to the top of the sliding rod 504, a sliding seat 506 fixedly connected to the top of the sliding plate 505, the fixed cylinder 501 fixedly connected inside the placement seat 2, the limiting plate 503 and the sliding rod 504 both slidably connected inside the fixed cylinder 501, the sliding seat 506 slidably connected to the placement seat 2, and the sliding plate 505 fixedly connected to the second rack 405.

[0039] The second rack 405 drives the sliding plate 505 to move upward. The sliding plate 505 and the sliding seat 506 move upward, so that the sliding seat 506 supports the plate-shaped semi-finished product, which is convenient for cutting. The sliding plate 505 drives the sliding rod 504 and the limiting plate 503 to move. The limiting plate 503 stretches the spring 502. After cutting, the electric push rod 302 drives the square plate 303 to move upward. The push rod 305 on the square plate 303 separates from the sliding frame 401. At this time, the spring 502 pushes the sliding plate 505 to reset. The sliding plate 505 drives the second rack 405 to reset.

[0040] In one embodiment, for the aforementioned mounting bracket 102, the outer surface of the mounting bracket 102 is threaded with bolts 7, and the mounting bracket 102 is fixedly mounted on the outer surface of the support plate 101 by bolts 7.

[0041] The method of fixing the installation with bolts 7 ensures a firm connection while facilitating disassembly and maintenance.

[0042] In one embodiment, the bottom of the support plate 101 is fixedly connected to a support leg 8.

[0043] The support leg 8 supports the support plate 101, so that the support plate 101 and the conveyor chain plate 104 have a certain height off the ground, which facilitates the picking and placing operations on the surface of the placement seat 2 on the conveyor chain plate 104.

The conveying component 1 continues to drive the placement seat 2 and the lamp bead to the under of the detector 6 for detection. There is no need for repositioning and long-distance transportation, reducing the time spent on connecting processes; 2. By connecting the second rack 405 and the sliding plate 505, the electric push rod 302 pushes the sliding frame 40 When the first rack 402 descends, the first rack 402 drives the sliding plate 505 to move upward through the gear 403 and the second rack 405, so that the sliding plate 505 drives the sliding seat 506 to move upward. At this time, the sliding seat 506 can support the plate-shaped semi-finished product, which is convenient for cutting. After the cutting is completed, the electric push rod 302 drives the push rod 305 to separate from the sliding frame 401. At this time, the spring 502 pulls the sliding plate 505 and the sliding seat 506 to reset, so that the cut lamp beads fall between the placement seat 2 and the sliding seat 506, preventing the lamp beads from sliding from the top of the placement seat 2 to the ground.
