Description

Technical Field

[0002] As the mainstream lighting components, SMD LED lamp beads have the advantages of high brightness, low power consumption, and long life, and are widely used in various lighting equipment, such as LED lighting, car taillights, and TV set-top boxes. The traditional LED packaging method is mainly through pin packaging, while the SMD packaging technology is to directly stick the LED chip on the substrate and then connect the LED chip and the substrate with wires. This technology has the advantages of small size, large capacity, and good reliability, and has gradually become the mainstream packaging method.

[0003] In the production process of SMD LED lamp beads, an efficient SMD device is needed to ensure that the LED chip can be accurately and stably attached to the substrate. Existing SMD devices may have problems such as insufficient precision and poor stability, which affect the production quality and efficiency of LED lamp beads. Therefore, developing a new type of LED lamp bead SMD device to improve the SMD precision and stability is of great significance to improving the production quality and efficiency of LED lamp beads.

[0004] For example, the specification of “A SMD device for LED lamp beads” disclosed in Chinese invention patent CN116997096A discloses that when the existing LED lamp beads are processed by SMD, they need to be clamped one by one by manual or mechanical clamps, and the LED lamp beads are placed on the surface of the SMD for processing, which has low work efficiency. After working for a long time, the position where the LED lamp beads are manually placed may be tilted, resulting in reduced quality of LED lamp bead production.

[0021] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0022] As described in the background art, the patch device may have problems such as insufficient precision and poor stability, which affect the production quality and efficiency of LED lamp beads.

[0023] In order to solve this technical problem, the present invention provides a patch device for LED lamp beads, which is used to improve the patch device during the patch process.

[0024] Specifically, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , a patch device for LED lamp beads specifically includes: A platform 1 and a driving motor 2 fixedly connected to its bottom for driving, an L-shaped combination platform 3 is arranged on the top of the platform 1, the bending part of the combination platform 3 is a fixed structure and the force angle will not change, a plurality of rectangular through grooves 4 are opened on the combination platform 3 and pass through the top of the combination platform 3 to the bottom of the combination platform 3, a patch component 5 is arranged on the combination platform 3, the patch component 5 includes an inner hollow platform 501 for adsorbing LED lamp beads, identification cameras 6 are fixedly connected to the ends of both sides of the L-shaped combination platform 3, material transport devices 7 are arranged on both sides of the platform 1, and a matching structure 8 is arranged on the platform 1.

[0025] The present invention provides a device for mounting LED lamp beads, which uses a separate adsorption inner space table 501 so that each LED lamp bead can have a separate air chamber for storage and adsorption during the mounting process, and can adapt to the mounting of lamp beads in different directions. At the same time, the L-shaped cross-loading is used to greatly reduce the time required for the loading process.

[0026] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0027] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0028] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0029] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 A patch device for LED lamp beads, the patch component 5 also includes a first fixed platform 502 fixedly connected to the inner wall of the combination platform 3, the first fixed platform 502 is fixedly connected to a first convex plate 503, the combination platform 3 is provided with linearly arranged airbag grooves 504, the first convex plate 503 is fixedly connected to a columnar airbag 505, and the first convex plate 503 is provided with a first through hole 506.

[0030] The columnar airbag 505 on one side of the inner hollow platform 501 is used as a power source, so that the extrusion part 516 existing outside the assembly platform 3 is squeezed by the shaking plate 805 during rotation to form an air pressure change and thus form a power source.

[0031] The patch assembly 5 also includes a second convex plate 507 which is arranged away from the first convex plate 503 and axially symmetrical with the inner hollow platform 501. A second through hole 508 is provided on the inner hollow platform 501. The central axes of the first through hole 506 and the second through hole 508 are on the same horizontal plane. A second fixed platform 509 is fixedly connected to the inner wall of the combination platform 3. The second convex plate 507 is fixedly connected to the second fixed platform 509. It should be supplemented that both sides of the inner hollow platform 501 are provided with recessed grooves for sliding with the first convex plate 503 and the second convex plate 507. The second through hole 508 is provided on the recessed groove of the inner hollow platform 501. A connecting pipe 510 is fixedly connected and connected to the bottom outer wall of the second fixed platform 509. A gradient air pipe 511 for providing additional airflow and whose diameter decreases step by step from top to bottom is fixedly connected and connected to the bottom outer wall of the connecting pipe 510.

[0032] By using different through holes at different levels, when the inner hollow platform 501 reaches different positions, the air pressure can be adjusted by misaligning the position of the through holes and the position of the inner hollow platform 501, so that the pressure inside a single inner hollow platform 501 changes and the order of gas outlet is changed.

[0033] Please refer to Figure 4 , Figure 5 , Figure 6 and Figure 7 A patch device for LED lamp beads, the patch component 5 also includes a buffer part 512 fixedly connected to the bottom of the inner empty platform 501 and connected thereto, a suction nozzle 513 is fixedly connected and connected to the bottom outer wall of the buffer part 512, and a suction groove 514 is provided on the suction nozzle 513, and the suction groove 514 is a superimposed groove of a rectangular groove and a circular groove, and a plurality of rectangularly arranged pin grooves 515 are provided around the end of the suction nozzle 513 that communicates with the inside and the outside.

[0034] The adsorption groove 514 adapted to the LED lamp beads allows the lamp beads to fit onto the adsorption nozzle 513 more quickly, and during the adsorption process, defective lamp beads can be screened through the pin groove 515, so that the deformed pins cannot generate adsorption force with the pin groove 515 and thus fall off.

[0035] The patch assembly 5 also includes a plurality of extrusion parts 516 fixedly connected to the assembly platform 3, and the extrusion parts 516 are linearly arranged on the assembly platform 3. A plurality of connecting air pipes 517 for connecting the extrusion parts 516 with the internal space of the columnar airbag 505 are fixedly connected and connected to the extrusion parts 516. The connecting air pipe 517 is only connected to a single extrusion part 516 and is connected to a single columnar airbag 505 with the shortest straight-line distance therefrom, that is, the shortest connecting air pipe 517 is the connecting part between the two extrusion parts 516 and the columnar airbag 505 at the corner of the assembly platform 3. The connecting air pipes 517 extending from the corner to both ends gradually become longer, and the shortest connecting air pipe 517 is at the bottom of the stacked connecting air pipes 517. The length of the connecting air pipes 517 from the bottom to the top gradually increases to prevent the connecting air pipes 517 from forming a convex squeeze on the shaking plate 805 due to staggered stacking.

[0036] By providing overlapping and gradually extending communicating air pipes 517, the airflow can be exhausted in coordination with the step-by-step movement of the rocking plate 805 after being moved in a rotating manner, that is, when the extrusion portion 516 is squeezed, it gradually fits against the rocking plate 805 one by one from the corner to both ends.

[0037] The patch component 5 also includes a rotating part 518 fixedly connected to the output end of the driving motor 2 through a coupling, the rotating part 518 is fixedly connected to the combination platform 3, the top of the rotating part 518 is fixedly connected to a fixed part 519 that is consistent with the shape of the combination platform 3, and a plurality of telescopic parts 520 are fixedly connected to the bottom outer wall of the fixed part 519, and the bottom of the telescopic part 520 is fixedly connected to the top outer wall of the inner hollow platform 501.

[0038] Example 2 further optimizes the LED lamp bead patch device provided in Example 1. Specifically, Figure 1, Figure 2 , Figure 3 , Figure 8 , Fig. 9 and Fig.14 As shown, the material transport device 7 includes a side wing platform 701 fixedly connected to both sides of the platform 1, an inner hollow tube 702 is fixedly connected to the top outer wall of the side wing platform 701, and a plurality of linearly arranged discharge troughs 703 are opened on the top of the inner hollow tube 702.

[0039] The symmetrically structured material transport device 7 enables materials to be loaded more quickly during the material transport process on the L-shaped assembly platform 3, thus saving loading time.

[0040] The material transport device 7 also includes a fixed plate 704 fixedly connected to both sides of the inner hollow tube 702. The fixed plate 704 is tiltedly arranged on the inner hollow tube 702. A threaded column 705 is rotatably connected to the fixed plate 704 through a bearing. It should be added that the threaded end of the threaded column 705 is a blunt part, so that the threaded column 705 can be driven by the material transport paper 708 without damaging the material transport paper 708.

[0041] Further, such as Figure 1 , Figure 2 , Figure 3 , Figure 8 , Fig. 9 and Fig.14 As shown, the material transport device 7 also includes a limiting roller 706 rotatably connected to the fixed plate 704, the threaded column 705 and both ends of the limiting roller 706 are arranged on the fixed plate 704, an internal roller 707 is rotatably connected to the inner wall of the inner hollow tube 702, a material transport paper 708 is arranged in the inner hollow tube 702, and both sides of the inner hollow tube 702 are provided with paper passing grooves for allowing the material transport paper 708 to pass through.

[0042] The transport paper 708 passes through the paper threading slot of the inner hollow tube 702, then passes out from the bottom of the threaded column 705, then passes upward between the threaded column 705 and the limiting roller 706, and finally contacts the upper surface of the limiting roller 706, passes vertically downward, and is collected by the receiving roller. Since the receiving roller and the driving structure are existing structures, they are not disclosed in this case.

[0043] Embodiment 3 further optimizes the LED lamp bead patch device provided in Embodiment 1 or 2. Specifically, Fig.10 , Fig.11 , Fig.12 and Fig.15The matching structure 8 includes a rotating base 801 fixedly connected to the platform 1, the rotating part 518 is arranged in the rotating base 801, a buffer belt 802 is hinged on the platform 1, a U-shaped rod 803 is fixedly connected to the platform 1, the other end of the buffer belt 802 is hinged to the U-shaped rod 803, a convex groove 804 is opened on the U-shaped rod 803, a shaking plate 805 is arranged in the U-shaped rod 803, and a plurality of dampers 806 are fixedly connected on both sides of the shaking plate 805. The shaking plate 805 is a rectangular structure, and two groups of dampers 806 are arranged on the long sides of the shaking plate 805, a total of four groups of dampers 806 are fixedly connected to the inner walls of the convex groove 804, and the damper 806 is provided with a return spring 807.

[0044] A rocking plate 805 that can move toward the buffer belts 802 on both sides is used, so that the rocking plate 805 can move in the horizontal plane and can move a certain distance after being squeezed, so that the two ends of the combination table 3 can maintain a vertical state with the processing belt after contacting the rocking plate 805.

[0045] The use process of the LED lamp bead patch device provided by the present invention is as follows: 1. During the use of the device, the PCB board or material that needs to be patched is conveyed to the bottom of the machine through a conveyor belt for patching. Fig.13 As shown, at this time, the single-sided assembly platform 3 reaches the direction of the shaking plate 805 and gradually overlaps with the shaking plate 805. The driving force of the driving motor 2 causes the L-shaped assembly platform 3 to rotate. When the assembly platform 3 gradually overlaps with the shaking plate 805, the columnar airbag 505 in the airbag groove 504 on the assembly platform 3 is squeezed with the shaking plate 805. At the same time, after being squeezed, the shaking plate 805 is slowly offset under the action of the damper 806 and the return spring 807. At the same time, the assembly platform 3 reaches the central position for patch mounting. 2. In this process, the other end of the assembly platform 3 away from the patch is close to the material transport device 7. Since the assembly platform 3 for patching is squeezed, the airflow inside the squeezing part 516 is transported to the columnar airbag 505 close to the material transport device 7 ready to start loading through the connecting air pipe 517, that is, the columnar airbag 505 at one end of the material transport device 7 close to the L-shaped assembly platform 3, that is, the connecting air pipe 517 cross-transports the airflow in the pipeline. At this time, since the inner empty platform 501 needs to be loaded, the telescopic part 520 can press down the inner empty platform 501 to connect the inner hollow space of the inner empty platform 501 with the first through hole 506 and the second through hole 508. At this time, the airflow moves in two directions of the adsorption nozzle 513 and the connecting pipe 510 through the internal circulation space. Most of the airflow passes through the adsorption nozzle 513 to remove dust from the LED lamp beads, and part of the airflow flowing to the connecting pipe 510 is ejected from the sharp nozzle through the gradient air pipe 511 for more effective cleaning. 3. At this time, the extrusion part 516 is still in an extruded state. When the suction nozzle 513 contacts the lamp bead, the rotating part 518 is driven by the driving motor 2 to rotate a certain distance, and the distance must not exceed the length of the discharge trough 703. Due to the deflection of a certain distance, the suction nozzle 513 moves a certain distance in the discharge trough 703 but does not separate. However, at this time, the extrusion part 516 has been separated from the shaking plate 805. The extrusion part 516 starts to reset and negative pressure is generated in the columnar airbag 505, causing the suction nozzle 513 to generate adsorption force. When the pins of the lamp bead are lifted When the pins are missing, the pin grooves 515 cannot be covered, causing the internal negative pressure to gradually weaken, but not instantly. When the telescopic portion 520 lifts the inner hollow platform 501, the suction nozzle 513 connected thereto is lifted at the same time, and the inner hollow platform 501 loses the connection effect with the first through hole 506 and the second through hole 508, and the negative pressure reaches equilibrium. The effective lamp beads are adsorbed on the suction nozzle 513, and the invalid or damaged lamp beads, after rising, cannot overcome the rotating gravity and the negative pressure effect gradually disappears, and perform parabolic motion and move toward the feeding paper 708. 4. There is nothing on the transport paper 708 at one end of the threaded column 705 and the limiting roller 706, but the transport paper 708 is in a stepping state under the action of the discharge roller and the receiving roller. Figure 8 The driving method is not disclosed. The empty feeding paper 708 on one side of the threaded column 705 forms a U-shaped net bag structure under the action of the threaded column 705 and the limiting roller 706. At this time, the damaged lamp bead falls into it. Since the threaded column 705 rotates during the stepping process, the damaged lamp bead gradually moves to both ends in the groove of the threaded column 705 and finally falls on the outermost side. 5. When the lamp beads are transported to the processing position, that is, above the conveyor belt, the extrusion part 516 above them is squeezed and provides airflow for the columnar airbag 505 at the other end. The recognition camera 6 corrects the deviation. The loading is repeated in this way. When the inner empty platform 501 performs the patch operation, it drops again under the action of the telescopic part 520. At this time, the space of the inner empty platform 501 is connected to the second through hole 508. Since the air intake capacity of the gradient air pipe 511 is weak, the internal negative pressure of the inner empty platform 501 is slowly broken, so that the lamp beads and the adsorption nozzle 513 are gradually separated during the patch process, ensuring external force interference during the patch process. It should be added that there is an adsorption nozzle 513 that drops through the gap of the buffer belt 802 during the patch operation.
