Description

Technical Field

[0001] This utility model relates to the field of LED lamp bead packaging and welding technology, specifically to an integrated automatic LED lamp bead welding and packaging machine. Background Technology

[0002] LED beads are light-emitting diodes, and they can be seen everywhere in our lives. LED beads have many advantages over ordinary light bulbs. They are very suitable for our use and are an energy-saving and emission-reducing lighting bulb. For environmental protection, LED lights are also the best choice for lighting. During the production of LED lights, multiple LED beads need to be packaged and soldered onto the same light board using reflow soldering technology to form an LED light.

[0003] However, existing welding and packaging equipment has certain defects in actual use. In the welding stage, most of them directly place the solder on the welding point, then place the LED on the solder paste, and then heat the whole thing to melt the solder paste into molten solder. However, due to the fluidity of the liquid during the melting process, the liquid may flow and the chip may tilt, affecting the quality of the product. Utility Model Content

[0004] The purpose of this invention is to provide an integrated automatic LED bead welding and packaging machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic LED lamp bead welding and packaging integrated machine, comprising a worktable and a substrate, wherein the substrate is placed on the worktable, and protective components are provided on both sides of the worktable via lifting components. Welding components are also provided on the worktable via an adjustment mechanism, and the welding components are matched with the substrate. Support legs are fixedly provided at the four corners of the bottom end of the worktable.

[0006] Preferably, in order to facilitate the up-and-down movement of the protective component, to facilitate the limiting protection during welding, and to facilitate the removal of the substrate after welding, the lifting component includes electric push rods equidistantly arranged on both sides of the substrate on the worktable, and a lifting plate is fixedly provided at the output end of the two electric push rods on the same side, with vertical plates equidistantly arranged on the lifting plate.

[0008] Preferably, in order to facilitate bringing the two plates closer and further apart, electromagnets are provided on the side walls of the two adjacent vertical plates, and permanent magnets matching the electromagnets are provided on the side walls of the end plates.

[0009] Preferably, in order to ensure stability during movement and prevent the pallet from slipping, a guide block is fixedly provided at the bottom end of the pallet, and a guide groove matching the guide block is provided on the lifting plate.

[0010] Preferably, in order to facilitate the movement and adjustment of the welding components and to facilitate welding operations, the adjustment mechanism includes hydraulic telescopic rods equidistantly arranged on the worktable, a fixed block fixedly provided at the output end of the hydraulic telescopic rod, and a linear guide rail device fixedly provided between the two fixed blocks on the same side, with a guide rail slider slidably fitted on the linear guide rail device.

[0011] Preferably, in order to facilitate the heating and melting of tin before welding the LED beads, the welding assembly includes a first movable plate and a second movable plate equidistantly arranged between two linear guide rail devices. Both sides of the first movable plate and the second movable plate are fixedly connected to the guide rail sliders, and heating blocks are equidistantly arranged below the first movable plate, and suction cups are equidistantly arranged below the second movable plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] With the addition of lifting components and protective components, the protective components can limit the area around the welding point during the welding process of the LED beads, thereby preventing the solder from flowing after it melts into liquid. At the same time, the welding components can be used to easily position the LED beads during welding, ensuring the quality of the welding and preventing tilting or other issues.

[0014] With its adjustable mechanism and welding components, the welding components can be easily moved and adjusted. This allows for convenient heating and melting of the solder during the welding process, followed by the extraction and movement of the LED beads, facilitating welding positioning and ensuring welding quality and effectiveness.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5This utility model provides an embodiment of an automatic LED bead welding and packaging integrated machine, including a worktable 1 for placing the LED lamp circuit board 9. A clamp (not shown in the figure, a mature technology, will not be described further) can be installed on the worktable 1 to facilitate clamping the board 9, ensuring that the board 9 will not slide during the welding and packaging process. Support legs 2 are vertically welded to the four corners of the bottom of the worktable 1, and fixed feet are welded to the bottom of the support legs 2 to ensure stability during placement and use. To prevent solder paste from flowing during installation, which could affect the soldering effect, and to ensure that the subsequent removal operation after soldering and shaping is not affected, electric push rods 10 with lifting components are symmetrically installed on both sides of the substrate 9 on the worktable 1 (the bottom part of the electric push rod 10 is embedded in the worktable 1). A lifting plate 11 is fixedly installed at the output end of the electric push rod 10. Vertical plates 12 are welded to the lifting plate 11 at equal intervals. A retaining plate 13 with protective components is symmetrically provided between two adjacent vertical plates 12. Limiting grooves 20 are equally spaced on the retaining plate 13. The number of retaining plates 13 and limiting grooves 20 is the same as the number of substrates 9 to be soldered. The number of LED beads corresponds one-to-one. The shapes of the card plate 13, the limiting groove 20, and the substrate 9 can be selected according to the actual situation, such as rectangular or circular, which are relatively mature technologies and will not be elaborated here. In order to facilitate the separation of the two card plates 13 after welding and packaging, and to facilitate the subsequent removal of the substrate 9, electromagnets 14 (mainly composed of energized coils and iron cores, etc., which are relatively mature technologies and will not be elaborated here) are glued to the side walls of the two adjacent vertical plates 12. The corresponding permanent magnets 15 that match the electromagnets 14 are glued to the end side walls of the card plates 13. To ensure the stability of the pallet 13 during movement, a guide block 17 is welded to the bottom end of the pallet 13. The lifting plate 11 is provided with a guide groove 16 to facilitate the reciprocating sliding of the guide block 17, which can ensure that the pallet 13 slides stably on the lifting plate 11. The cross-sectional shape of the guide block 17 can also be T-shaped, and the guide groove 16 is correspondingly provided to prevent the pallet 13 from slipping during movement. The worktable 1 is also provided with a dispensing machine (not shown in the figure). The dispensing machine coats the area around the welded LED beads with epoxy resin or silicone, and then cures it. This is a relatively mature technology, and will not be described in detail here.

[0023] Please see Figures 1-5To facilitate the heating and melting of solder paste and the suction and soldering of LED beads, a hydraulic telescopic rod 3 with an adjustment mechanism is vertically installed on the workbench 1. A fixing block 4 is fixedly installed at the output end of the hydraulic telescopic rod 3. A linear guide rail device 5 is fixedly installed between the two fixing blocks 4 on the same side by screws. A guide rail slider 6 is slidably fitted on the linear guide rail device 5. It can be driven by a linear motor or by other methods to achieve reciprocating movement, such as a reciprocating screw and motor. This is a relatively mature technology and will not be elaborated here. Between the two linear guide rail devices 5, there are two moving plates 7 and 8. Both sides of the moving plates 7 and 8 are fixed to the guide rail slider 6 (by screws). Heating blocks 18 are installed at equal intervals under the moving plate 7, and suction cups 19 are installed at equal intervals under the moving plate 8. The number of heating blocks 18 and suction cups 19 is... The number of LED beads to be soldered on the substrate 9 corresponds one-to-one. For the heating block 18, the moving plate 7 is equipped with a heating device (not shown in the figure), which can be achieved by electric heating (the temperature can be 260-320℃, or other temperatures, depending on the actual situation). The suction cup 19 can be used to pick up the LED beads by negative pressure vacuuming. The suction cup 19 is connected to the output end of the vacuum generator (not shown in the figure) through a connecting pipe. It is a relatively mature technology, which will not be described in detail here. It can facilitate the picking up of LED beads, thereby facilitating subsequent soldering and packaging. One end of the worktable 1 (the end near the moving plate 8, which is convenient for picking up LED beads) can be equipped with a conveying device (which can be a conveyor belt or vibratory plate, etc., to facilitate the conveying of LED beads to be soldered and packaged, and to facilitate subsequent picking up; or it can be a placement tray, with the LED beads on the placement tray corresponding one-to-one with the suction cup 19, which is convenient for picking up).

[0024] Working Principle: In use, when welding and encapsulating the LED beads, the substrate 9 is placed on the workbench 1. The electric push rod 10 retracts, causing the lifting plate 11 to move downwards. At this point, the clamping plate 13 contacts the top of the substrate 9. The electromagnet 14 is energized, generating a repulsive force on the permanent magnet 15. This, in conjunction with the guide block 17 and guide groove 16, brings the two clamping plates 13 between adjacent vertical plates 12 closer together, and the limiting groove 20 is spliced, thus limiting the solder at the welding point. Then, the hydraulic telescopic rod 3 retracts, causing the fixing block 4 to move downwards. Simultaneously, the heating block 18 heats the solder, melting it. At the same time, the suction cup 19 under the moving plate 8 contacts the LED beads. Contact is made by drawing the LED beads through negative pressure vacuum. After melting, the hydraulic telescopic rod 3 extends and resets, the linear guide rail device 5 works, and the guide rail slider 6 moves, thereby moving the first moving plate 7 away from the substrate 9 and the second moving plate 8 directly above the substrate 9. Then the hydraulic telescopic rod 3 retracts and resets, placing the LED beads under the suction cup 19 on the molten solder, which can then be soldered and packaged. After cooling and shaping, the electromagnet 14 is energized (with reverse current), which attracts the permanent magnet 15. Then the two clamping plates 13, together with the guide block 17 and the guide groove 16, slide away and lose the limiting effect. Then the electric push rod 10 extends, moving the lifting plate 11 upward as a whole without affecting the removal of the substrate 9, thus completing the soldering and packaging operation.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
