Description

Technical Field

[0001] This application relates to the technical field of LED production equipment, and in particular to a base for surface mount LED production. Background Technology

[0002] Surface mount LEDs (SMD LEDs) are a simple type of lighting fixture. Their light-emitting principle involves passing an electric current through a compound semiconductor; the excess energy from the combination of electrons and holes is released as light, thus achieving the light-emitting effect. They are mainly used in lighting systems, decoration, electronic device indicators, backlighting, displays, and instruments. SMD LEDs emit light coldly, rather than through heating or discharging, resulting in a long lifespan. Due to their unique advantages, SMD LEDs have been widely applied and developed in various fields. With continuous technological advancements and cost reductions, the market prospects for SMD LEDs will be even broader. In the manufacturing and assembly process of SMD LEDs, the substrate plays a crucial role as a key component supporting and positioning the LED chip and its related components. With the continuous advancement of LED technology and the increasing miniaturization and integration of electronic products, the requirements for SMD LED substrates are also increasing.

[0003] Traditional bases used in SMD LED production are inconvenient for limiting and fixing SMD LED floor tiles of different sizes, and are not easy to adjust in height to improve the efficiency of SMD LED production, thus having certain drawbacks.

[0004] Therefore, in order to solve the above problems, this application provides a base for surface mount LED production. Utility Model Content

[0005] The purpose of this invention is to provide a base for surface mount LED production to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a base for surface mount LED production, comprising a base, telescopic rods installed at the four corners of the top of the base, the base being mounted on the top of the telescopic rods, a sliding groove formed on the top of the base, a servo motor mounted on one side wall of the inner side of the sliding groove, a bidirectional threaded rod mounted on the output shaft of the servo motor, movable plates symmetrically mounted at both ends of the outer ring surface of the bidirectional threaded rod, dampers symmetrically mounted at both ends of the outer side of the movable plates, a limit plate mounted at one end of the dampers, and fixed plates symmetrically mounted at the two longer edges of the bottom of the base, with inclined grooves formed on the outer surface of the fixed plates.

[0007] Preferably, the end of the bidirectional threaded rod away from the servo motor is rotatably connected to the other side wall of the slide groove, the outer ring surface of the bidirectional threaded rod is threadedly connected to the interior of the two movable plates, and the bottom of the movable plate is slidably connected to the top of the base.

[0008] Preferably, a fixing block is installed at a shorter edge of the top of the base, an electric telescopic rod is installed at one end of the fixing block, and a connecting block is installed on the movable end of the electric telescopic rod.

[0009] Preferably, cylindrical blocks are installed at both ends of the connecting block and inside the two inclined grooves, and the outer ring surface of the cylindrical blocks is slidably connected to the inside of the inclined grooves.

[0010] Preferably, support plates are symmetrically installed at both ends of the bottom of the connecting block, and the bottom of the support plates is slidably connected to the top of the base.

[0011] Preferably, a protective pad is installed on the outer side of the limiting plate away from the damper.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] This type of base for surface mount LED production features a servo motor-driven bidirectional threaded rod. When the rod rotates, two movable plates move relative to or towards each other along the thread direction. A sliding connection between the bottom of the movable plates and the top of the base ensures stability during movement, facilitating the positioning and fixing of surface mount LED base plates of different sizes. The position of the connecting block can be adjusted by extending and retracting the electric telescopic rod. When the electric telescopic rod extends or retracts, the connecting block drives a cylindrical block to slide within a sloping groove. This sliding and pressing action of the cylindrical block against the fixed plate causes the two fixed plates and the base to rise and fall, while the telescopic rod extends and retracts simultaneously for height adjustment. This enhances the efficiency of surface mount LED production, offers convenient operation, and has a wider range of applications. Attached Figure Description

Detailed Implementation

[0019] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0020] A base for surface mount LED production, reference Figure 1 - Figure 4 The system includes a base 1, with telescopic rods 2 installed at the four corners of the top of the base 1. A base 3 is installed on the top of the telescopic rods 2. A sliding groove 301 is provided on the top of the base 3. A servo motor 4 is installed on one side wall of the inner side of the sliding groove 301. A bidirectional threaded rod 5 is installed on the output shaft of the servo motor 4. Movable plates 6 are symmetrically installed at both ends of the outer ring surface of the bidirectional threaded rod 5. A damper 7 is symmetrically installed at both ends of the outer side of the movable plate 6. A limit plate 8 is installed at one end of the damper 7. Fixed plates 9 are symmetrically installed at the two longer edges of the bottom of the base 3. An inclined groove 901 is provided on the outer side of the fixed plate 9.

[0021] Reference Figure 1 - Figure 2 The end of the bidirectional threaded rod 5 away from the servo motor 4 is rotatably connected to the other side wall of the slide groove 301. The outer ring surface of the bidirectional threaded rod 5 is threadedly connected to the inside of the two movable plates 6. The bottom of the movable plate 6 is slidably connected to the top of the base 3. When the servo motor 4 drives the bidirectional threaded rod 5 to rotate, the two movable plates 6 will move relative to each other or towards each other along the thread direction of the bidirectional threaded rod 5. The slidable connection between the bottom of the movable plate 6 and the top of the base 3 ensures that the movable plate 6 remains stable when moving, thereby facilitating the limiting and fixing of LED substrates of different sizes.

[0022] Reference Figure 3 - Figure 4 A fixing block 10 is installed on a shorter edge of the top of the base 1. An electric telescopic rod 11 is installed on one end of the fixing block 10. A connecting block 12 is installed on the movable end of the electric telescopic rod 11. The position of the connecting block 12 can be adjusted by extending and retracting the electric telescopic rod 11.

[0023] Reference Figure 3 - Figure 4Cylindrical blocks 13 are installed at both ends of the connecting block 12 and inside the two inclined grooves 901. The outer ring surface of the cylindrical block 13 is slidably connected to the inside of the inclined groove 901. When the electric telescopic rod 11 extends or retracts, the connecting block 12 drives the cylindrical block 13 to slide in the inclined groove 901. Thus, the cylindrical block 13 slides and presses the fixing plate 9 inside the inclined groove 901, thereby driving the two fixing plates 9 and the base 3 to rise and fall, and the telescopic rod 2 extends and retracts at the same time to adjust the height, thereby enhancing the efficiency of LED chip production.

[0024] Reference Figure 3 - Figure 4 Support plates 14 are symmetrically installed at both ends of the bottom of the connecting block 12. The bottom of the support plate 14 is slidably connected to the top of the base 1. By setting two sets of support plates 14 to slide between the base 1, the stability of the movement of the connecting block 12 is increased.

[0025] Reference Figure 1 - Figure 2 A protective pad 15 is installed on the outer side of the limiting plate 8 away from the damper 7. The protective pad 15 can provide cushioning and protection to ensure the safety of the surface mount LED during the production process.

[0026] The implementation principle of a base for surface mount LED production according to an embodiment of this application is as follows: During the surface mount LED production process, the base plate of the surface mount LED is first placed on top of the base 3 and located between two limiting plates 8. Then, when the bidirectional threaded rod 5 is rotated by the servo motor 4, the two movable plates 6 will move relative to or towards each other along the thread direction of the bidirectional threaded rod 5. The bottom of the movable plate 6 and the top of the base 3 are slidably connected to ensure that the movable plate 6 remains stable during movement, thereby facilitating the limiting and fixing of surface mount LED base plates of different sizes. The position of the connecting block 12 can be adjusted by the extension and retraction of the electric telescopic rod 11. When the electric telescopic rod 11 extends and retracts, the connecting block 12 drives the cylindrical block 13. The cylindrical block 13 slides within the inclined groove 901, thereby pressing the fixed plate 9 by sliding within the inclined groove 901. This causes the two fixed plates 9 and the base 3 to rise and fall, while the telescopic rod 2 extends and retracts simultaneously for height adjustment, thereby enhancing the efficiency of LED chip production. By setting two sets of support plates 14 to slide between the base 1 and the base, the stability of the connecting block 12 movement is increased. The damper 7 and the protective pad 15 can provide buffering and protection effects, ensuring the safety of the chip LED during the production process. The threads on both sides of the bidirectional threaded rod 5 have opposite opening directions, equal pitch, and a thread opening angle of 20 degrees. The thread self-locking condition needs to meet the following formula calculation: Self-locking condition = friction coefficient * tan (helix angle) ≥ 1.
