Description

Technical Field

[0001] This invention relates to the field of LED bead testing technology, specifically a vision-based LED bead production testing and sorting device. Background Technology

[0002] Traditional LED chip testing methods largely rely on manual visual inspection or semi-automatic testing equipment. Manual visual inspection suffers from high labor intensity, low efficiency, and susceptibility to errors and omissions due to fatigue; it is also highly subjective, making it difficult to standardize testing criteria. While existing semi-automatic testing equipment alleviates the burden of manpower to some extent, it still has many limitations:

[0003] 1. Most equipment lacks an efficient automatic feeding and positioning mechanism. The position and orientation of the LED beads on the carrier (especially the pin direction) are highly random, resulting in inconsistent image positions captured by the detection camera, which seriously affects the accuracy and reliability of the detection algorithm.

[0004] 2. Traditional clamping mechanisms are often single-function and cannot simultaneously perform flexible and precise positioning and correction of the LED body and the delicate pins.

[0005] 3. The lighting method during the inspection process is also crucial. Ordinary lighting is prone to reflections and shadows, or uneven lighting due to obstruction by the clamping mechanism, which can mask real defects or create false defects. Moreover, sorting after inspection mostly requires additional equipment or manual operation, failing to form an efficient closed loop with the inspection process, and there is still room for improvement in overall production efficiency.

[0006] Therefore, it is necessary to provide a vision-based LED bead production inspection and sorting device to solve the problems mentioned in the background art. Summary of the Invention

The adjustment seat is fixedly disposed at the bottom of the support plate. A sliding groove is provided in the adjustment seat through one end of the adjustment seat. Two sliders are slidably disposed opposite each other in the sliding groove. Two deflection grooves are symmetrically disposed at one end of the sliders protruding from the sliding groove.

[0012] Preferably, an I-shaped pull rod is slidably provided at the end of the slider away from the slide groove, four pull blocks are fixedly provided on the pull rod, and a spring is provided between the pull rod and the slider;

[0013] The deflection rod has grooves on both its upper and lower sides, and two pull blocks on the rod located in the same vertical direction slide along the same grooves on both sides of the deflection rod.

[0014] Preferably, the top of the fixed block is provided with a guide rail mechanism, which includes a first straight rail, an end block, a connecting rod and a second straight rail. The first straight rail is fixedly disposed on the fixed block and its rail direction is consistent with the extension and retraction direction of the hydraulic telescopic rod. The end block is slidably disposed on one end of the first straight rail. The first straight rail and the end block are provided with a first straight groove, and the connecting rod is slidably disposed in the first straight groove.

[0019] In this invention, the clamping mechanism and the adjustment mechanism can actively correct the position and orientation of the LED beads and their pins, ensuring that each LED bead has a completely consistent detection position when it arrives at the camera's field of view. This eliminates false detections or missed detections caused by positional differences, guaranteeing high precision and repeatability of visual inspection. Simultaneously, the clamping mechanism and the adjustment mechanism can slide together under the sliding of the moving plate and adjust their height under the action of the first hydraulic telescopic rod. This allows the clamping mechanism and the adjustment mechanism to effectively position and clamp LED beads of different models, effectively expanding their applicability. Furthermore, after inspection, the clamping mechanism can drive multiple second hydraulic telescopic rods to retract and squeeze the LED beads based on the inspection results. This allows qualified and unqualified LED beads to be extruded from the discharge ports on both sides of the base plate and both sides of the inspection frame, respectively, and then transported by the corresponding second feeding mechanism. This achieves automatic sorting of LED beads, effectively improving inspection accuracy and efficiency. Attached Figure Description

[0028] Please see Figures 1 to 7 In this embodiment of the invention, a vision-based LED bead production inspection and sorting device includes a transmission mechanism 1, an inspection frame 2, a first feeding mechanism 3, a second feeding mechanism 4, and clamping components 5. The inspection frame 2 is fixedly installed on the transmission mechanism 1. A feeding port is opened on one side of the inspection frame 2 near the input end of the transmission mechanism 1. The first feeding mechanism 3 is provided at the feeding port. Two discharge ports are symmetrically opened on both sides of the inspection frame 2 near the output end of the transmission mechanism 1. The second feeding mechanism 4 is provided at the discharge ports. Multiple clamping components 5 are fixedly installed on the transmission mechanism 1.

[0029] The clamping assembly 5 includes a base plate 51, a movable plate 52, a clamping mechanism 53, and an adjusting mechanism 54. The base plate 51 is fixedly installed on the transmission mechanism 1. Movable plates 52 are symmetrically slidably arranged on both sides of the base plate 51 by hydraulic drive. Two hydraulic telescopic rods 521 are fixedly arranged on the movable plate 52. The output ends of the two hydraulic telescopic rods 521 are fixedly arranged with the clamping mechanism 53. The bottom of the clamping mechanism 53 is provided with the adjusting mechanism 54.

[0030] A backlight 56 ​​is embedded in the center of the base plate 51, and a pin assembly 57 is slidably disposed on the base plate 51 around the outer ring of the backlight 56.

[0031] In addition, the detection frame 2 is also equipped with a coaxial light, a dome light, a ring light, a low-angle light, and a detection camera for visual inspection of LED beads.

[0032] In implementation, the LED beads are placed on the first feeding mechanism 3, and then the first feeding mechanism 3 transports the LED beads to the transmission mechanism 1. The clamping component 5 on the first feeding mechanism 3 adjusts the position and placement of the LED beads, ensuring that the LED beads transported to the first feeding mechanism 3 maintain the same placement position under the action of the clamping component 5. At the same time, the clamping component 5 clamps the LED beads to prevent them from shifting during the transport process. As a result, when the LED beads are transported to the detection camera inside the detection frame 2, the detection position of each LED bead is the same, thus ensuring high accuracy and high reliability of the detection. After the detection is completed, the clamping component 5 can output the LED beads from both sides of the base plate 51, that is, from both sides of the first feeding mechanism 3, and then transport the qualified and unqualified products to two second feeding mechanisms 4 respectively, so as to sort the LED beads. That is, to automatically detect and sort the LED beads, thereby improving the detection efficiency of the LED beads.

[0033] In this embodiment, as Figures 2-6 The clamping mechanism 53 includes a support plate 531, a second hydraulic telescopic rod 532, and a first guide wheel 533. The support plate 531 is fixedly disposed at the output end of the first hydraulic telescopic rod 521. Multiple second hydraulic telescopic rods 532 are evenly distributed along the length of the support plate 531, and the extension direction of the second hydraulic telescopic rod 532 is towards the width direction of the support plate 531. The first guide wheel 533 is rotatably disposed at the output end of the second hydraulic telescopic rod 532.

[0034] The adjustment mechanism 54 includes an adjustment seat 541, a slider 542, a deflection rod 543, a hydraulic telescopic rod 544, a fixing block 545, and a guide wheel 546. The adjustment seat 541 is fixedly installed at the bottom of the support plate 531. A groove is provided in the adjustment seat 541, penetrating one end of the adjustment seat 541. Two sliders 542 are slidably arranged opposite each other in the groove. Two deflection grooves are symmetrically opened at the end of each slider 542 protruding from the groove. A deflection rod 543 is rotatably installed in the deflection groove. A hydraulic telescopic rod 544 is fixedly installed in the deflection rod 543. A fixing block 545 is fixedly installed at the output end of the hydraulic telescopic rod 544. A rotating shaft 547 is slidably installed at the bottom of the fixing block 545 through hydraulic drive. A guide wheel 546 is rotatably installed on the rotating shaft 547. Both the hydraulic telescopic rod 544 and the hydraulic telescopic rod 532 are multi-stage telescopic rods, that is, they have a long telescopic stroke while having a small shrinkage volume.

[0035] In this embodiment, as Figure 4 and Figure 6 Hydraulic telescopic rods 5411 are fixedly installed on both sides of the slide groove. The two hydraulic telescopic rods 5411 are staggered. The two sliders 542 are fixedly connected to the output ends of the two hydraulic telescopic rods 5411 respectively. The sliders 542 have through holes for the hydraulic telescopic rods 5411 that are not fixedly connected to them to slide through. The minimum contracted length of the hydraulic telescopic rods 5411 is equal to half the length of the slide groove.

[0036] The slider 542 is slidably provided with an I-shaped pull rod 5421 at one end away from the slide groove. Four pull blocks 5422 are fixedly provided on the pull rod 5421, and a spring is provided between the pull rod 5421 and the slider 542.

[0037] The deflection rod 543 has grooves 5431 on both the upper and lower sides at an incline. Two pull blocks 5422 on the pull rod 5421 located in the same vertical direction are slidably arranged along the grooves 5431 on both the upper and lower sides of the same deflection rod 543.

[0038] In implementation, two hydraulic telescopic rods 5411 drive the two sliders 542 to slide. When one hydraulic telescopic rod 5411 drives the slider 542 to slide, the other hydraulic telescopic rod 5411 passes through the through hole of the slider 542, thus restricting the sliding of the slider 542 and ensuring its sliding stability. At the same time, when the two deflecting rods 543 open and deflect to both sides, the pull block 5422 slides along the pull groove 5431, thereby driving the pull rod. 5421 slides along the slider 542 and squeezes the first spring. Under the restriction of the pull rod 5421, the deflection angle of the two deflection rods 543 is always the same, that is, they deflect synchronously. When the deflection rods 543 are not under force, that is, when the guide wheel 546 is detached from the lamp bead and is not under pressure, the first spring will drive the pull rod 5421 to reset and slide, so that the two deflection rods 543 reset their deflection. That is, the deflection rods 543 will return to their initial state, which facilitates the next adjustment of the position of the lamp bead and the lamp bead pin.

[0039] During implementation, when the first conveying mechanism 3 transfers the LED beads to the base plate 51, the LED beads are located on one side of the base plate 51. Based on the model and specifications of the LED beads, the hydraulic telescopic rod 521 is driven to extend or retract, causing the clamping mechanism 53 and the adjusting mechanism 54 to rise or fall, ensuring that the clamping mechanism 53 and the adjusting mechanism 54 are above the LED bead pins. Subsequently, multiple hydraulic telescopic rods 532 are driven to extend, causing multiple guide wheels 533 to abut against both sides of the LED beads. Then, the hydraulic telescopic rod 532 fixed in the middle of the support plate 531 stops extending or retracting. Then, multiple hydraulic telescopic rods 532 near the LED beads are sequentially driven to retract, causing the LED beads to be squeezed and conveyed to the center of the base plate 51. At this time, the multiple hydraulic telescopic rods 532 will... The first guide wheel 533 is driven to conform to the shape of the LED bead and clamp it. During this process, the sliding of the first guide wheel 533, located in the middle of the support plate 533, will cause the second straight rail 554 to slide together. This will cause the fixing block 545 to be pulled and slide together under the action of the connecting rod 553 and the first straight rail 551. During this process, the third hydraulic telescopic rod 544 will be pulled to passively extend and retract. At this time, according to the position of the LED bead pin, the rotating shaft 547 in the fixing block 545 on the two second straight rails 554, which is opposite to the pin, will extend. This will cause the second guide wheel 546 to slide downward, that is, the second guide wheel 546 will descend to contact the LED bead pin. Then, the slider 54 in the adjusting seat 541 connected to the second guide wheel 546 will be driven. 2. Slide the adjustment seat 541 to the middle position, i.e., slide it to the middle position of the lamp bead. Then drive the hydraulic telescopic rod 3 544 to extend, so that the guide wheel 2 546 also abuts against the lamp bead. At this time, continue to drive the hydraulic telescopic rod 3 544 to extend, so that the two guide wheels 2 546 slide along the surface of the lamp bead. At the same time, the deflection rod 543 and the hydraulic telescopic rod 3 544 deflect. As the guide wheel 2 546 slides along the surface of the lamp bead, it will contact the pin of the lamp bead and push the pin of the lamp bead to slide together, i.e. drive the lamp bead to rotate. The rotation will stop when the two guide wheels 2 546 on both sides of the pin are simultaneously in contact with both sides of the pin. During this process, the lamp bead will be driven to rotate, so that the pins on both sides of the lamp bead are in a parallel position with the clamping mechanism 53. Then, in the lamp... When the LED bead is conveyed to the area below the detection camera within the detection frame 2, the hydraulic telescopic rods 532 and 544 are slightly loosened, and the LED bead is lifted using the ejector pin assembly 57. Simultaneously, the backlight 56 ​​is turned on, ensuring it faces the back of the LED bead without being blocked by the clamping mechanism 53 or the adjustment mechanism 54. After detection, the ejector pin assembly 57 is retracted, and the hydraulic telescopic rod 532 is retracted to re-clamp the LED bead. The hydraulic telescopic rod 544 is then retracted, freeing the LED bead's leads. Based on the detection results, when the LED bead is conveyed to the discharge ports on both sides of the detection frame 2, the combined pressure of the multiple hydraulic telescopic rods 532 and the guide roller 533 forces the LED bead to be extruded from both sides of the base plate 51.Based on the test results, qualified and unqualified LED beads are output from two separate outlets and conveyed to the second conveying mechanism 4, thus completing the automatic detection and sorting of LED beads with higher detection accuracy and efficiency.

[0040] In this embodiment, as Figure 3 , Figure 5 and Figure 6 The top of the fixing block 545 is provided with a guide rail mechanism 55. The guide rail mechanism 55 includes a first straight rail 551, an end block 552, a connecting rod 553 and a second straight rail 554. The first straight rail 551 is fixedly installed on the fixing block 545, and its rail direction is consistent with the extension and retraction direction of the hydraulic telescopic rod 544. The end block 552 is slidably installed on one end of the first straight rail 551. The first straight rail 551 and the end block 552 are jointly provided with a first straight groove 555. The connecting rod 553 is slidably installed in the first straight groove 555.

[0041] The second straight rail 554 is fixedly installed at the output end of the second hydraulic telescopic rod 532 located in the middle of the support plate 531, and its rail direction is perpendicular to the extension and retraction direction of the second hydraulic telescopic rod 532. A second straight groove 556 is provided on the second straight rail 554, and the other end of the connecting rod 553 is slidably installed in the second straight groove 556.

[0042] In this embodiment, as Figure 7 The end block 552 is fixedly provided with a plurality of T-shaped limiting rods 557. The first straight rail 551 is provided with a limiting groove for the limiting rods 557 to slide, and a spring is provided between the limiting rods 557 and the first straight rail 551.

[0043] Specifically, the first straight rail 551 and the end block 552 can be regarded as a telescopic straight rail structure. When the hydraulic telescopic rod 544 extends, the fixed block 545 will disengage from the second straight rail 554, and the connecting rod 553 will slide along the first straight rail 551 and the second straight rail 554. This ensures that there is always a limiting connection between the fixed block 545 and the hydraulic telescopic rod 532 located in the middle of the support plate 531. That is, it ensures that the hydraulic telescopic rod 532 can drive the fixed block 545 to move together when it slides. At the same time, when the hydraulic telescopic rod 544 slides, the fixed block 545 can disengage from the second straight rail 554. This ensures that the adjustment mechanism 54 can adjust the position of the lamp bead and the pin of the lamp bead, and ensures that each lamp bead is placed outside the body in the same way during testing.

[0044] In summary, when implemented, this invention utilizes the clamping mechanism 53 and the adjusting mechanism 54 to actively correct the position and orientation of the LED beads and their pins, ensuring that each LED bead has a completely consistent detection position when it reaches the camera's field of view. This eliminates false detections or missed detections caused by positional differences, guaranteeing high precision and repeatability of visual inspection. Simultaneously, the clamping mechanism 53 and the adjusting mechanism 54 can slide together under the sliding of the moving plate 52 and adjust their height under the action of the hydraulic telescopic rod 521. This allows the clamping mechanism 53 and the adjusting mechanism 54 to effectively position and clamp LED beads of different models, effectively expanding their applicability. Furthermore, after inspection, the clamping mechanism 53 can drive multiple hydraulic telescopic rods 532 to retract and squeeze the LED beads based on the inspection results. This allows qualified and unqualified LED beads to be extruded from the discharge ports on both sides of the base plate 51 and the inspection frame 2, respectively, and transported by the corresponding second conveying mechanism 4. This achieves automatic sorting of LED beads, effectively improving inspection accuracy and efficiency.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
