Description

Technical Field

[0001] This invention relates to the field of LED chip fabrication, specifically to a fluorescent glass arrangement apparatus and method for fabricating high-reliability LED devices. Background Technology

[0002] An LED chip is a solid-state semiconductor device. The heart of an LED is a semiconductor chip. One end of the chip is attached to a support, which is the negative electrode, and the other end is connected to the positive electrode of the power supply. The entire chip is encapsulated in epoxy resin. With the rapid development of LED technology and the gradual improvement of LED luminous efficacy, the application of LEDs will become more and more widespread.

[0003] During LED chip fabrication, the chip needs to be soldered onto a substrate made of inorganic materials such as ceramics or glass. A metal dam is constructed on the substrate, and steps are made on top of the dam to hold fluorescent glass material. Existing Chinese patent document CN113675316A discloses a UV-LED device and its manufacturing method, which uses an inorganic dam attached to an inorganic substrate to enclose the semiconductor light-emitting chip within it. Compared to substrates made of organic materials, this method offers excellent resistance to ultraviolet radiation. The inorganic substrate, inorganic dam, and glass cover are all welded or bonded together through an inorganic welding layer, without any organic adhesives, resulting in high connection strength, good sealing performance, and true all-inorganic encapsulation. This provides radiation resistance, long lifespan, and good resistance to sulfidation and halogenation. However, during deployment, if the glass cover is not aligned with the inner side of the dam, repeated fine-tuning of the glass cover's position is required. Due to the small size of the glass cover, fine-tuning is difficult, and the glass cover may detach from the entire dam, causing damage. Summary of the Invention

[0004] The purpose of this invention is to provide a fluorescent glass arrangement apparatus and method for preparing high-reliability LED devices, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0007] Preferably, the material placement mechanism includes a mounting box fixedly installed at the bottom of the mounting frame. Four centrally symmetrically distributed fixing plates are fixedly installed on the inner side of the mounting box. Spring telescopic rods are fixedly installed on the outer sides of the fixing plates. A push plate is fixedly installed at the end of the spring telescopic rod away from the fixing plates. A mounting block is provided on the side of the push plate away from the spring telescopic rod. A groove is provided on the outer side of the mounting box for limiting and sliding of the mounting block, providing limitation and guidance for the movement of the mounting block. A stop plate is fixedly installed at the bottom of the mounting block. The bottom of the stop plate has a sloped structure, facilitating contact between the stop plate and the outer side of the glass cover and the metal dam. An electric suction cup is fixedly installed at the bottom of the mounting box. The bottom of the electric suction cup is located above the slope of the stop plate, allowing the electric suction cup to adhere to the glass cover. Three equally spaced sliders are fixedly installed on the side of the push plate near the mounting block. A sliding groove is provided on the outer side of the mounting block for limiting and sliding of the sliders. A spring is fixedly installed between the bottom of the slider and the inner side of the sliding groove, facilitating the stop plate to abut against the top of the substrate.

[0008] Preferably, the clamping mechanism includes a positioning rod rotatably mounted inside the mounting box, a gear fixedly mounted on the outer side of the positioning rod, and a rack plate cooperating with the gear fixedly mounted on the side of the push plate away from the mounting block. The height of the gear is greater than the height of the rack plate. When any one rack plate moves, the other three rack plates can be driven to move synchronously through the gear. A limiting slide cavity is formed on the outer side of the rack plate. Two symmetrically distributed slide bars are fixedly mounted on the top and bottom of the inner side of the mounting box. The four slide bars are slidably mounted in the limiting slide cavities of the four rack plates to improve the stability of the rack plate movement. A guide rod is fixedly mounted on the side of the push plate near the rack plate. A cavity is formed on the inner side of the slide bar for the guide rod to be inserted into, preventing the push plate from tilting during movement.

[0009] Preferably, the clamping mechanism includes a ratchet rotatably mounted on the top of the positioning rod. The ratchet is located on the top of the mounting box. Two positioning plates symmetrically distributed on the outside of the ratchet are fixedly mounted on the top of the mounting box. A limiting plate is fixedly mounted on the side of the positioning plate away from the ratchet. A sliding rod that slides through the positioning plate is fixedly mounted on the side of the limiting plate near the positioning plate. A insertion frame is fixedly mounted on the end of the sliding rod away from the limiting plate. A locking tooth that cooperates with the ratchet is fixedly mounted on the side of the insertion frame away from the sliding rod, so that the ratchet rotates in one direction and prevents the ratchet from rotating back. A U-shaped frame is fixedly mounted on the outside of the fixed end of the electric telescopic rod. A stop block is fixedly mounted on the inside of the insertion frame. Two push blocks are fixedly mounted on the bottom of the U-shaped frame, each located directly above the two stop blocks. The top and bottom of the stop blocks are corresponding inclined structures. When the push block contacts the stop block, it can push the insertion frame to move through the stop block, thereby unlocking the ratchet with the locking tooth. A spring is fixedly mounted between the positioning plate and the insertion frame.

[0010] Preferably, a limiting rod that slides through the slider is fixedly installed on the inner side of the groove of the mounting block to improve the stability of the mounting block when it moves.

[0011] Preferably, the inner side of the limiting cavity of the rack plate and the outer side of the slide bar are both arc-shaped structures to prevent the slide bar from falling out of the limiting cavity.

[0012] Preferably, the side of the rack plate away from the gear contacts the outer side of the fixed plate to improve the smoothness of the rack plate's movement.

[0013] Preferably, a guide frame is fixedly installed on the side of the positioning plate near the insertion frame, and the insertion frame is slidably installed on the inner side of the guide frame to facilitate the installation and movement of the insertion frame.

[0014] Preferably, a stop plate is fixedly installed on the top of the positioning rod, and the stop plate is located above the ratchet to prevent the ratchet from contacting the bottom of the U-shaped frame.

[0015] One arrangement method, the steps of which are as follows:

[0016] S1: Filling stage, the chip is soldered onto the substrate, silicon oxide particles are loaded into the inside of the metal dam, and the silicon oxide particles are spread evenly between the inside of the metal dam and the chip.

[0017] S2: During the material handling stage, start the drive carriage to move the mounting bracket at the bottom of the electric telescopic rod to the top of the glass cover plate. Start the electric telescopic rod to move the four abutments along the outside of the glass cover plate, so that the electric suction cup can adhere to the middle position of the glass cover plate.

[0018] S3: Positioning stage, the top of the glass cover is attracted by the electric suction cup, the drive carriage moves the glass cover at the bottom of the electric suction cup to the top of the metal dam, the electric telescopic rod is activated, so that the mounting box moves the bottom plates of the four mounting blocks to the outside of the metal dam, so that the glass cover at the bottom of the electric suction cup is aligned with the inside of the metal dam.

[0019] S4: During the material placement stage, the electric telescopic rod is activated again to make the support plate press against the top of the substrate. The glass cover plate at the bottom of the electric suction cup is inserted into the inside of the metal dam, and the metal dam and glass cover plate are heated and welded together to form a sealed structure.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. This invention, through its material placement mechanism, provides pre-clamping to the outer side of the glass cover plate during material handling, facilitating stable adsorption of the top of the glass cover plate. Furthermore, it ensures the glass cover plate remains horizontal during the horizontal displacement of the drive carriage. Additionally, it provides protection to the outer side of the glass cover plate when it is inserted into the metal dam, ensuring a smooth insertion and solving the problem of the glass cover plate easily detaching from the metal dam. This effectively improves the installation accuracy of the glass cover plate and the metal dam.

[0022] 2. The present invention, through the clamping mechanism, enables the other three rack plates to move synchronously via gears when any one rack plate moves, facilitating the quick clamping and positioning of the outer side of the glass cover plate by the abutment plate, improving the material handling efficiency of the glass cover plate, and thus achieving the effect of rapid material handling.

[0023] 3. The present invention, through the fixed clamping mechanism, can prevent the gear from rotating when it rotates by the cooperation of the ratchet and the locking teeth, thus preventing the abutment plate from colliding with the glass cover plate when it is in contact with the metal dam, improving the safety of the glass cover plate installation, and thus achieving the desired installation effect.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figures 1-8 The diagram illustrates a fluorescent glass arrangement device for fabricating high-reliability LED devices. It includes a base 1 and a drive slide 2 fixedly mounted on the top of the base 1. An electric telescopic rod 3 is fixedly mounted on the moving end of the drive slide 2, enabling the drive slide 2 to move the electric telescopic rod 3. A substrate 4 is positioned on the top of the base 1, a metal dam 5 is positioned on the top of the substrate 4, a chip 6 is positioned inside the metal dam 5, and a glass cover plate 7 is positioned on the top of the metal dam 5. A mounting frame 8 is fixedly mounted on the output end of the electric telescopic rod 3. The device also includes: a material placement mechanism for quickly aligning the glass cover plate 7 with the inner side of the metal dam 5, the material placement mechanism being mounted on the bottom of the mounting frame 8; an adjusting clamping mechanism for quickly positioning the glass cover plate 7, the adjusting clamping mechanism being mounted on the bottom of the mounting frame 8; and a fixed clamping mechanism for continuously picking up multiple glass cover plates 7, the fixed clamping mechanism being mounted on the bottom of the mounting frame 8.

[0035] The material placement mechanism includes a mounting box 9 fixedly installed at the bottom of the mounting frame 8. Four centrally symmetrically distributed fixing plates 10 are fixedly installed on the inner side of the mounting box 9. Spring telescopic rods 11 are fixedly installed on the outer side of the fixing plates 10. A push plate 12 is fixedly installed at the end of the spring telescopic rod 11 away from the fixing plate 10. A mounting block 13 is provided on the side of the push plate 12 away from the spring telescopic rod 11. A groove is provided on the outer side of the mounting box 9 for limiting and sliding the mounting block 13, providing limitation and guidance for the movement of the mounting block 13. A stop plate 14 is fixedly installed at the bottom of the mounting block 13. The bottom of the mounting box 9 has a sloping structure, which facilitates the contact between the abutment plate 14, the glass cover plate 7, and the outer side of the metal dam 5. An electric suction cup 15 is fixedly installed at the bottom of the mounting box 9. The bottom of the electric suction cup 15 is located above the sloping surface of the abutment plate 14. The glass cover plate 7 is adsorbed by the electric suction cup 15. Three sliders 16 are fixedly installed on the side of the push plate 12 near the mounting block 13. A groove is opened on the outer side of the mounting block 13 for the sliders 16 to slide in a limited manner. A spring 17 is fixedly installed between the bottom of the slider 16 and the inner side of the groove, which facilitates the abutment plate 14 to abut against the top of the substrate 4.

[0036] When the electric telescopic rod 3 moves the mounting box 9 at the bottom of the mounting bracket 8, the mounting box 9 can cause the bottom abutment plate 14 of the mounting block 13 to contact the outer side of the glass cover plate 7, so that the inclined surface of the abutment plate 14 abuts against the top of the glass cover plate 7. Utilizing the elasticity of the spring telescopic rod 11, the outer side of the abutment plate 14 abuts against the side of the glass cover plate 7. The four abutment plates 14 can elastically clamp the outer side of the glass cover plate 7. As the mounting box 9 moves, the electric suction cup 15 contacts the top of the glass cover plate 7, ensuring that the electric suction cup 15 adsorbs the middle position of the top of the glass cover plate 7. And when the drive slide 2 drives the electric telescopic rod 11 to move, the electric telescopic rod 14 will move. When the retractor 3 moves, the four abutments 14 can keep the glass cover 7 moving in a horizontal state. Before the glass cover 7 contacts the inner side of the metal dam 5, the inclined surface of the abutment 14 can abut against the outer side of the metal dam 5, so that the abutment 14 is away from the glass cover 7, and the bottom of the abutment 14 contacts the top of the base plate 4. Using the reaction force of the abutment 14, the limiting slide cavity on the mounting block 13 moves along the outer side of the slider 16, compressing the spring 17. The glass cover 7 can then be smoothly inserted into the inner side of the metal dam 5, thereby improving the installation accuracy of the glass cover 7 and the metal dam 5.

[0037] The clamping mechanism includes a positioning rod 18 rotatably mounted inside the mounting box 9. A gear 21 is fixedly mounted on the outer side of the positioning rod 18. A rack plate 19 that cooperates with the gear 21 is fixedly mounted on the side of the push plate 12 away from the mounting block 13. The height of the gear 21 is greater than the height of the rack plate 19. When any rack plate 19 moves, the other three rack plates 19 can be driven to move synchronously through the gear 21. A limiting slide cavity is opened on the outer side of the rack plate 19. Two symmetrically distributed slide bars 20 are fixedly mounted on the top and bottom of the inner side of the mounting box 9. The four slide bars 20 are slidably mounted in the limiting slide cavities of the four rack plates 19 to improve the stability of the movement of the rack plates 19. A guide rod 22 is fixedly mounted on the side of the push plate 12 close to the rack plate 19. A cavity is opened on the inner side of the slide bar 20 for the guide rod 22 to be inserted into the limiting cavity to prevent the push plate 12 from tilting when moving.

[0038] When the mounting block 13 moves, the slider 16 can pull the push plate 12 to move, causing the push plate 12 to drive the rack plate 19 to move along the outer side of the slide bar 20, and drive the guide rod 22 to move along the inner side of the slide bar 20, causing the rack plate 19 to drive the gear 21 to rotate. Thus, when any mounting block 13 moves, the rack plate 19 corresponding to that mounting block 13 can drive the other three rack plates 19 to move synchronously, ensuring the synchronous movement of the four abutment plates 14, increasing the contact speed between the abutment plates 14 and the side of the glass cover plate 7 or the metal dam 5, preventing the abutment plates 14 from putting too much pressure on the glass cover plate 7, improving the material picking efficiency of the glass cover plate 7, and thus achieving the effect of rapid material picking.

[0039] Working principle: First, the operator places the chip 6 inside the metal dam 5, making the chip 6 contact the top of the substrate 4, and then spreads silicon oxide particles evenly on the inside of the metal dam 5. Next, the operator activates the drive slide 2, which moves the electric telescopic rod 3 above the glass cover 7. Subsequently, the electric telescopic rod 3 moves the mounting box 9 at the bottom of the mounting bracket 8 downwards. The mounting box 9 moves the four mounting blocks 13 synchronously, causing the mounting blocks 13 to bring the abutment plate 14 into contact with the outer side of the glass cover 7. The inclined surface of the abutment plate 14 abuts against... At the top of the glass cover 7, the elasticity of the spring telescopic rod 11 causes the outer side of the abutment plate 14 to abut against the side of the glass cover 7. Simultaneously, the abutment plate 14 moves the mounting block 13, which in turn moves the push plate 12 synchronously via the slider 16. This causes the push plate 12 to move the corresponding rack plate 19 along the outer side of the slide bar 20. The rack plate 19 then rotates the gear 21, causing the gear 21 to move the other three rack plates 19 synchronously. Thus, the four abutments 14 elastically clamp the outer side of the glass cover 7. Meanwhile, the mounting box 9 continues to move downwards, securing the glass cover 7. The electric suction cup 15 at the bottom of the mounting box 9 contacts the top of the glass cover 7, causing the electric suction cup 15 to adhere to the middle position of the top of the glass cover 7. Then, the drive carriage 2 is driven again, moving the electric telescopic rod 3 above the metal dam 5. The electric telescopic rod 3 moves the mounting box 9 downward, so that the inclined surface of the abutment plate 14 abuts against the outside of the metal dam 5. The abutment plate 14 can then move away from the glass cover 7. At this time, the bottom of the abutment plate 14 contacts the top of the substrate 4. Using the reaction force of the abutment plate 14, the limit on the mounting block 13 is lifted. The sliding cavity moves along the outside of the slider 16 and compresses the spring 17. The electric suction cup 15 can then smoothly insert the glass cover plate 7 into the inside of the metal dam 5. The abutment plate 14 can protect the outside of the glass cover plate 7 and prevent the glass cover plate 7 from detaching from the metal dam 5. Finally, the electric telescopic rod 3 drives the abutment plate 14 and the electric suction cup 15 away from the glass cover plate 7. The workers then heat and weld the metal dam 5 and the glass cover plate 7 together to form a sealed structure, thus completing the preparation of the LED device and achieving the effect of stable installation and safe preparation.

[0040] Example 2: Please refer to Figure 2 , Figure 7 and Figure 8This embodiment further illustrates Example 1. The clamping mechanism shown in the figure includes a ratchet 23 rotatably mounted on the top of the positioning rod 18. The ratchet 23 is located on the top of the mounting box 9. Two positioning plates 24 symmetrically distributed outside the ratchet 23 are fixedly mounted on the top of the mounting box 9. A limiting plate 25 is fixedly mounted on the side of the positioning plate 24 away from the ratchet 23. A sliding rod 26 that slides through the positioning plate 24 is fixedly mounted on the side of the limiting plate 25 near the positioning plate 24. A insertion frame 27 is fixedly mounted on the end of the sliding rod 26 away from the limiting plate 25. A component that interacts with the ratchet is fixedly mounted on the side of the insertion frame 27 away from the sliding rod 26. The locking teeth 28, which are matched with the ratchet 23, allow the ratchet 23 to rotate in one direction and prevent the ratchet 23 from turning back. A U-shaped frame 29 is fixedly installed on the outside of the fixed end of the electric telescopic rod 3. A stop block 30 is fixedly installed on the inside of the insertion frame 27. Two push blocks 31 are fixedly installed at the bottom of the U-shaped frame 29, which are located directly above the two stop blocks 30. The top of the stop block 30 and the bottom of the push block 31 are corresponding inclined structures. When the push block 31 contacts the stop block 30, it can push the insertion frame 27 to move through the stop block 30, so that the locking teeth 28 are away from the ratchet 23. A spring 22 is fixedly installed between the positioning plate 24 and the insertion frame 27.

[0041] In this embodiment: when gear 21 drives positioning rod 18 to rotate, positioning rod 18 can drive ratchet 23 to rotate synchronously, causing ratchet 23 to push cleat 28 to move. By using cleat 28 to limit ratchet 23, ratchet 23 can only rotate in one direction, thus keeping gear 21 stationary. This prevents spring telescopic rod 11 from pulling push plate 12, causing excessive clamping force of abutment 14 on glass cover 7. Furthermore, when abutment 14 moves away from glass cover 7, it will not suddenly reset, improving the safety of abutment 14 in positioning glass cover 7. When the electric... When the telescopic rod 3 pulls the mounting box 9 upward, the mounting box 9 causes the insertion frame 27 to contact the push block 31 at the bottom of the U-shaped frame 29. The inclined surface of the push block 31 contacts the inclined surface of the abutment block 30, causing the push block 31 to push the insertion frame 27 to move through the abutment block 30. The insertion frame 27 causes the locking teeth 28 to move away from the ratchet 23 and compress the second spring 32, thereby unlocking the ratchet 23. When the push block 31 moves away from the insertion frame 27, the rebound force of the second spring 32 causes the locking teeth 28 to contact the ratchet 23 again, thereby improving the safety of the glass cover plate 7 when picking up materials.

[0042] Example 3: Please refer to Figures 4-8This embodiment further illustrates other embodiments. In the figure, a limiting rod 33 for sliding through the slider 16 is fixedly installed inside the groove of the mounting block 13. The inner side of the limiting slide cavity of the rack plate 19 and the outer side of the slider 20 are both arc-shaped structures to prevent the slider 20 from falling out of the limiting slide cavity. The side of the rack plate 19 away from the gear 21 contacts the outer side of the fixing plate 10 to improve the stability of the movement of the rack plate 19. A guide frame 34 is fixedly installed on the side of the positioning plate 24 near the insertion frame 27. The insertion frame 27 is slidably installed inside the guide frame 34 to facilitate the installation and movement of the insertion frame 27. A baffle 35 is fixedly installed on the top of the positioning rod 18. The baffle 35 is located above the ratchet 23 to prevent the ratchet 23 from contacting the bottom of the U-shaped frame 29.

[0043] In this embodiment: when the mounting block 13 moves upward, it can drive the limiting rod 33 to move along the inner side of the slider 16, improving the stability of the movement of the mounting block 13. The arc-shaped structure on the outer side of the slide bar 20 can prevent the rack plate 19 from detaching from the slide bar 20 during movement, providing auxiliary support for the rack plate 19. The rack plate 19 can also move along the outer side of the fixing plate 10, improving the stability of the movement of the rack plate 19. When the push block 31 pushes the insert frame 27 to move through the abutment block 30, the insert frame 27 can move along the inner side of the guide frame 34, facilitating the installation and movement of the insert frame 27. Furthermore, the bottom of the U-shaped frame 29 can contact the top of the baffle 35, preventing the top of the ratchet 23 from being worn by the U-shaped frame 29 when the ratchet 23 rotates.

[0048] S4: During the material placement stage, the electric telescopic rod 3 is activated again, so that the abutment plate 14 abuts against the top of the substrate 4.
