Description

Technical Field

[0001] This application relates to LED sorting, and more particularly to an LED sorting and releasing mechanism with multi-size compatible suction nozzles. Background Technology

[0002] With the rapid development of LED technology and the continuous expansion of LED chip production scale, the requirements for sorting efficiency and accuracy are becoming increasingly stringent. Traditional LED sorting technologies mainly rely on manual or semi-automatic equipment, resulting in low efficiency, poor accuracy, and high costs. Currently, common LED sorting technologies include mechanical sorting, optical sorting, and electromagnetic sorting. In recent years, automated sorting technology has gradually become the mainstream.

[0003] Currently, when sorting LED components, a vacuum generator is required. However, most existing vacuum generators are equipped with a single vacuum suction cup. This single vacuum suction cup is difficult to adapt to different sizes of LED components due to size differences. Therefore, the vacuum suction cup needs to be changed frequently by hand to adapt to the specifications of the LED components to be sorted. This frequent manual change leads to a reduction in production efficiency.

[0004] Regarding the relevant technologies mentioned above.

[0005] 1. Technical problems to be solved The purpose of this application is to provide an LED sorting and releasing mechanism with multi-specification adaptable vacuum suction cups, which solves the problem that frequent manual replacement of vacuum generators of vacuum suction cups will reduce production efficiency.

[0006] This application provides an LED sorting and placing mechanism with multi-specification adaptable nozzles, which adopts the following technical solution: it includes a main body, a suction cup replacement structure, a suction structure, a feeding structure, an infeed structure, and a guiding structure. The suction cup replacement structure includes a first fixed frame, and the suction structure includes a third electric telescopic rod. The first fixed frame is fixedly connected to one side of the main body, and a first electric telescopic rod is fixedly connected to one side of the first fixed frame. Multiple assembly blocks are fixedly connected to the outer wall of the telescopic rod of the first electric telescopic rod. A second electric telescopic rod is fixedly connected to the bottom end of each of the multiple assembly blocks. An assembly block is fixedly connected to the output end of each of the multiple second electric telescopic rods. An assembly block is fixedly connected to each of the multiple third electric telescopic rods. An assembly frame is fixedly connected to the output end of each of the multiple third electric telescopic rods. A vacuum suction cup is fixedly connected to one side of each of the multiple assembly frames. By adopting the above technical solution, during use, based on the specifications of the LED components to be sorted, the first, second, and third electric telescopic rods are used. By pre-adjusting the extension lengths of these three rods, the corresponding vacuum suction cups are determined, allowing them to pick up the LED components. This setup, by using different sized vacuum suction cups to correspond to different sized LED components, enables rapid switching of the appropriate vacuum suction cup based on the LED specifications, eliminating the need for frequent manual changes. Furthermore, depending on the specifications of the LED components to be sorted, the vacuum pressure generated by the vacuum device (which includes an external air source, a triplet, a manifold, a solenoid valve, and connecting parts and air pipes) can be pre-adjusted to prevent over-suction damage and weak adhesion leading to detachment of the vacuum suction cups during adsorption.

[0007] Preferably, the multiple vacuum suction cups are of different sizes, and the multiple vacuum suction cups are used in conjunction with a solenoid valve and an air manifold and a triplet. The upper end of the main body has multiple slots arranged in a linear array, and each of the multiple slots is provided with a collection box. The feeding structure includes an annular T-shaped slider, the feeding structure includes a second fixing frame, and the guiding structure includes a third fixing frame.

[0008] By adopting the above technical solution, the vacuum suction cup can be used in conjunction with the external air source, triplet, manifold, solenoid valve and other components after it is turned on, so that the vacuum suction cup can pick up the corresponding LED components.

[0009] Preferably, a first base is fixedly connected to one side of the main body, a first motor is fixedly connected to one side of the first base, a gear is fixedly connected to the output shaft of the first motor, a mounting platform is fixedly connected to the upper end of the main body, and an annular groove is formed in the middle of the mounting platform.

[0010] By adopting the above technical solution, the first motor is started to make the gear mesh with the gear ring, thereby driving the main platform to rotate.

[0011] Preferably, the annular T-shaped slider is slidably connected to the inside of the annular groove, a main platform is fixedly connected to the outside of the annular T-shaped slider, a toothed ring is fixedly connected to the outside of the main platform, the toothed ring meshes with a gear, and multiple material support grooves arranged in an annular array are opened on the outer wall of the main platform. Protrusions are fixedly connected between the multiple material support grooves, and the multiple material support grooves correspond to the vacuum suction cup.

[0012] By adopting the above technical solution, the first motor is started to make the gear mesh with the gear ring, thereby driving the main platform to rotate, while the annular T-shaped slider slides in the annular groove. At the same time, the LED element is discharged from the second feeding channel and falls into a material support groove at the top of the main platform.

[0013] Preferably, the second fixing frame is fixedly connected to the upper end of the mounting platform, and a feeding tray is fixedly connected to the upper end of the second fixing frame. The inner wall of the feeding tray is inclined. A guide shell is connected to one side of the feeding tray. A first feeding channel is connected to the bottom end of the guide shell. A vertical rod is slidably connected to the upper end of the guide shell. A horizontal plate is fixedly connected to one end of the vertical rod. A baffle is fixedly connected to the end of the horizontal plate away from the vertical rod. The baffle is located at the feed inlet of the guide shell. A threaded rod is threadedly sleeved in the middle of the horizontal plate. The bottom end of the threaded rod is rotatably connected to the upper end of the guide shell. A second base is fixedly connected to the bottom end of the feeding tray. A vibrating motor is fixedly connected to the bottom end of the second base.

[0014] By adopting the above technical solution, the output frequency of the oscillating motor is then adjusted as needed to regulate the oscillation frequency, thereby ensuring a stable oscillation frequency. The oscillation force is then transmitted to the material feeding tray.

[0015] Preferably, the third fixing frame is fixedly connected to the upper end of the mounting platform, a third base is fixedly connected to one side of the third fixing frame, a third motor is fixedly connected to the upper end of the third base, a disc is fixedly connected to the output shaft of the third motor, a cylinder is fixed to one side edge of the disc, and a slide rod is slidably connected to one side of the third fixing frame through a T-shaped slide groove.

[0016] By adopting the above technical solution, the LED element slides along the inclined slope of the first and second feeding channels. At this time, the third motor is started, which drives the disc to rotate. During the rotation of the disc, the cylinder drags the frame to move.

[0017] Preferably, a support rod is fixedly connected to the end of the slide rod away from the third fixed frame, a frame is fixedly connected to the upper end of the support rod, the frame is fitted over the cylinder, a sponge block is fixedly connected to the bottom end of the support rod, and a second feeding channel is fixedly connected to one side of the third fixed frame.

[0018] By adopting the above technical solution, the sponge block at the bottom of the support rod can be in contact with the LED element, causing the passing LED element to be temporarily stopped, thereby forming a gap between multiple LED elements.

[0019] Preferably, the second feeding channel is connected to the first feeding channel, and multiple cover plates are slidably connected to the upper end of the second feeding channel. The upper end of the second feeding channel has a groove adapted to the sponge block, and the second feeding channel corresponds to multiple material support grooves.

[0020] By adopting the above technical solution, the vibration force is continuously applied to the LED component, further preventing the accumulation and blockage of the feed inlet. Subsequently, the LED component enters the second feed channel through the first feed channel.

[0021] 2. Technical problems to be solved: This LED sorting and releasing mechanism with multi-size compatible suction nozzles, during use, determines the corresponding vacuum suction cup size based on the specifications of the LED components to be sorted, through the setting of a first, second, and third electric telescopic rod. By pre-adjusting the extension lengths of the first, second, and third electric telescopic rods, the appropriate vacuum suction cup is selected to pick up the LED component. This setup allows for quick switching of the appropriate vacuum suction cup based on the LED's specifications, eliminating the need for frequent manual changes. Furthermore, the vacuum pressure generated by the vacuum device (which includes an external air source, a triplet, a manifold, a solenoid valve, and connecting parts and air pipes) can be pre-adjusted according to the required LED component specifications, preventing over-suction damage and weak adhesion leading to detachment during suction.

[0022] This LED sorting and dispensing mechanism with multi-specification compatible nozzles, through the setting of a feeding tray, guide shell, horizontal plate, baffle, threaded rod, and oscillating motor, allows for adjustment of the oscillating motor's output frequency during use, ensuring a stable oscillation frequency. Simultaneously, the operator tightens the threaded rod according to the thickness of the inserted LED model, raising or lowering the horizontal plate fitted on the outer wall of the threaded rod. The upright rod acts as a vertical limit, thereby blocking the LED components and preventing multiple materials from overlapping and causing blockage in the guide shell. Furthermore, the oscillation force continuously acts on the LED components, preventing blockage and overlap after dispensing, and the oscillation further prevents accumulation and blockage at the guide shell's inlet.

The upper end is fixedly connected to the second fixed frame 501, and a feeding tray 502 is fixedly connected to the upper end. The inner wall of the feeding tray 502 is inclined. A guide shell 503 is connected to one side of the feeding tray 502. The bottom end of the guide shell 503 is connected to the first feeding channel 504. A vertical rod 505 is slidably connected to the upper end of the guide shell 503. A horizontal plate 506 is fixedly connected to one end of the vertical rod 505. A baffle 507 is fixedly connected to the end of the horizontal plate 506 away from the vertical rod 505. The baffle 507 is located at the feed inlet of the guide shell 503. A threaded rod 508 is threadedly sleeved in the middle of the horizontal plate 506. The bottom end of the threaded rod 508 is rotatably connected to the upper end of the guide shell 503. A second base 509 is fixedly connected to the bottom end of the feeding tray 502. The bottom end of the second base 509 is fixed. A vibration motor 510 is connected. A third fixing bracket 701 is fixedly connected to the upper end of the mounting platform 12. A third base 702 is fixedly connected to one side of the third fixing bracket 701. A third motor 703 is fixedly connected to the upper end of the third base 702. A disc 704 is fixedly connected to the output shaft of the third motor 703. A cylinder 705 is fixed to one edge of the disc 704. A slide rod 706 is slidably connected to one side of the third fixing bracket 701 via a T-shaped slide groove. A support rod 707 is fixedly connected to the end of the slide rod 706 away from the third fixing bracket 701. A frame sleeve 708 is fixedly connected to the upper end of the support rod 707. The frame sleeve 708 is fitted over the cylinder 705. A sponge block 709 is fixedly connected to the bottom end of the support rod 707. A third fixing bracket 701 is fixed to one side of the third fixing bracket 701. A second feeding channel 710 is fixedly connected to the first feeding channel 504. Multiple cover plates 711 are slidably connected to the upper end of the second feeding channel 710. A groove adapted to the sponge block 709 is opened at the upper end of the second feeding channel 710. The second feeding channel 710 corresponds to multiple material support slots 404. Through the arrangement of the first electric telescopic rod 202, the second electric telescopic rod 204, the third electric telescopic rod 301, the assembly frame 302, and the vacuum suction cup 303, during use, when the thickness of the LED component is known during feeding, the first electric telescopic rod 202 is activated in conjunction with the thickness of the LED component, extending the telescopic rod to the set length.The system moves the appropriate vacuum suction cup 303 to the position corresponding to the LED component. Then, the second electric telescopic rod 204 and the third electric telescopic rod 301 extend, allowing the vacuum suction cup 303 to contact the LED component. The vacuum suction cup 303, through a triplet and solenoid valve, outputs a suitable suction force with the manifold, preventing damage to the LED component due to over-suction or loose adhesion. This ensures the suction nozzle is properly matched to the LED component. Furthermore, by pre-knowing the thickness of the LED component during the unloading process, the positions of multiple vacuum suction cups 303 can be adjusted, saving time required for changing vacuum suction cups 303 and thus improving work efficiency.

[0028] The implementation principle of this application embodiment is as follows: First, the LED components to be sorted are placed into the feeding tray 502 at the upper end of the second fixed frame 501. Then, the output frequency of the oscillation motor 510 is adjusted as needed to regulate the oscillation frequency and ensure a stable oscillation frequency. Subsequently, the oscillation force is transmitted to the feeding tray 502, causing the inner LED components to move due to vibration. At this time, the worker turns the threaded rod 508 according to the thickness of the LED model placed in, causing the horizontal plate 506 sleeved on the outer wall of the threaded rod 508 to rise or fall. The upright rod 505 acts as a vertical limit, thereby enabling the baffle 507 to block the LED components and prevent multiple raw materials from overlapping and entering the guide shell 503, causing blockage. At the same time, the oscillation force continues to act on the LED components, further preventing accumulation and blockage at the feed inlet of the guide shell 503. Subsequently, the LED components enter the second feeding channel 710 through the first feeding channel 504. The LED components then slide along the inclined slopes of the first feeding channel 504 and the second feeding channel 710. At this point, the third motor 703 is activated, driving the disc 704 to rotate. Simultaneously, as the disc 704 rotates, the cylinder 705 drags the frame 708 to move. The frame 708, limited by the sliding rod 706 on one side of the support rod 707, continuously rises and falls vertically. During this time, the sponge block 709 at the bottom of the support rod 707 can come into contact with the LED components, briefly stopping the passing LED components and thus creating spacing between multiple LED components. The first motor 8 is activated, causing the gear 9 to mesh with the gear ring 403, thereby driving the main table 402 to rotate. The annular T-shaped slider 401 slides within the annular groove 13. Simultaneously, the LED element is discharged from the second unloading channel 710 and falls into a material support groove 404 at the upper end of the main table 402. This triggers the activation of the first electric telescopic rod 202, extending it to a set length and moving the adapted vacuum suction cup 303 to the corresponding workstation. As the main stage 402 moves multiple LED components, the thickness of the LED components is predicted during the unloading process. Then, based on the thickness of the LED components, the first electric telescopic rod 202 is activated, extending to a set length. This moves the matching vacuum suction cup 303 to the corresponding workstation position of the LED component. Subsequently, the second electric telescopic rod 204 and the third electric telescopic rod 301 extend, and the vacuum suction cup 303 contacts the LED component. The vacuum suction cup 303 outputs a suitable suction force through a triplet and a solenoid valve connected to the manifold. Afterward, the second electric telescopic rod 204 retracts, with the degree of retraction at different positions precisely corresponding to the multiple collection boxes 11 at the bottom. After the telescopic rods return to their original positions, the LED components are placed into the corresponding collection boxes 11, completing the sorting process.
