Description

Technical Field

[0001] This utility model relates to the field of LED chip lamp bead production technology, specifically to an adjustable-spacing LED chip lamp bead arrangement device. Background Technology

[0002] LED chip chips emit light based on the PN junction principle. When a forward bias voltage is applied to the PN junction, the potential barrier decreases, and the majority carriers in the P and N regions diffuse towards each other. Since the electron mobility is much greater than the hole mobility, a large number of electrons diffuse into the P region and recombine with holes in the valence band. The energy generated during recombination is released in the form of light energy.

[0003] If the spacing between LED chips cannot be adjusted during the chip mounting process, the wiring and solder joint layout of the PCB board must match the spacing between the chips. When the chips are working, they generate heat. If the spacing is too dense, it may lead to insufficient heat dissipation space and accelerate chip aging. If the spacing is too sparse, it may waste PCB board area and increase material costs. Therefore, an adjustable spacing LED chip chip arrangement device is proposed. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides an adjustable-spacing LED chip bead arrangement device, which solves the problem of inconvenient LED chip bead arrangement.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: an adjustable-spacing LED chip lamp bead arranging device, including a mounting machine, wherein the inner wall of the mounting machine is provided with a storage groove; The placement machine is equipped with an adjustment mechanism, which includes a hydraulic unit, a hydraulic rod, a fixed frame, a motor, a slide, a fixed roller, a first bevel gear, a second bevel gear, a bidirectional threaded rod, a movable nut, a support rod, a movable plate, an LED placement head, and a vacuum nozzle. The two hydraulic actuators are fixedly installed in the inner wall of the storage tank, and the two hydraulic rods are slidably sleeved in the inner wall of the two hydraulic actuators respectively; The fixed frame is fixedly installed at the lower end of the two hydraulic rods, and eight sliding grooves are opened on the opposite sides of the two horizontal plates of the fixed frame; The motor is fixedly installed on the right surface of the fixed frame, and the output end of the motor passes through the inner wall of the horizontal plate of the fixed frame. The fixed roller is rotatably connected to the inner wall of the horizontal plate of the fixed frame, and the right end of the fixed roller is fixedly connected to the output end of the motor. Two first bevel gears are fixedly sleeved on the outer surface of the fixed roller, and two second bevel gears are respectively meshed and connected to the outer surfaces of the two first bevel gears; The two bidirectional threaded rods are respectively fixedly sleeved in the inner walls of the two second bevel gears, and the two bidirectional threaded rods are rotatably connected to the inner wall of the fixed frame; The four movable nuts are respectively threaded onto the outer surfaces of the two bidirectional threaded rods, and the eight support rods are respectively rotatably connected to the outer surfaces of the four movable nuts; The four movable plates are rotatably connected to the ends of the eight support rods away from the four movable nuts, and the four movable plates are slidably connected to the eight sliding grooves respectively.

[0006] (III) Beneficial Effects Compared with the prior art, this utility model provides an adjustable-spacing LED chip lamp bead arrangement device, which has the following beneficial effects: 1. This adjustable-spacing LED chip lamp bead arranging equipment uses a motor to drive a fixed roller to rotate. Through the transmission of the first and second bevel gears, the bidirectional threaded rod rotates, causing the moving nut to move in the opposite direction. The moving plate is pushed along the slide groove by the support rod, allowing the four vacuum nozzles to adjust their spacing synchronously. This linkage structure ensures consistent spacing adjustment, accurately matches the arrangement requirements of different specifications of lamp beads, and improves the mounting accuracy and efficiency.

[0007] 2. This adjustable-spacing LED chip lamp bead arrangement equipment uses a hydraulic actuator to drive the hydraulic rod to extend and retract, thereby raising and lowering the fixed frame, the motor below, the fixed roller, the lamp bead placement head, and other components as a whole.

[0010] 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.

[0011] Please see Figure 1-4 This utility model provides a new technical solution: an adjustable spacing LED chip lamp bead arrangement device, including a mounting machine 1, and a storage groove 2 is provided on the inner wall of the mounting machine 1; The mounting machine 1 is equipped with an adjustment mechanism, which includes a hydraulic actuator 3, a hydraulic rod 4, a fixed frame 5, a motor 6, a slide 7, a fixed roller 8, a first bevel gear 9, a second bevel gear 10, a bidirectional threaded rod 11, a movable nut 12, a support rod 13, a movable plate 14, a lamp bead mounting head 15, and a vacuum nozzle 16.

[0012] Furthermore, two hydraulic actuators 3 are fixedly installed in the inner wall of the storage trough 2, and two hydraulic rods 4 are slidably sleeved in the inner wall of the two hydraulic actuators 3 respectively.

[0013] Furthermore, the fixed frame 5 is fixedly installed at the lower end of the two hydraulic rods 4, and eight sliding grooves 7 are opened on the opposite sides of the two horizontal plates of the fixed frame 5.

[0014] Furthermore, the motor 6 is fixedly installed on the right surface of the fixed frame 5, and the output end of the motor 6 penetrates into the inner wall of the horizontal plate of the fixed frame 5. The fixed roller 8 is rotatably connected to the inner wall of the horizontal plate of the fixed frame 5, and the right end of the fixed roller 8 is fixedly connected to the output end of the motor 6.

[0015] Furthermore, two first bevel gears 9 are fixedly sleeved on the outer surface of the fixed roller 8, and two second bevel gears 10 are respectively meshed and connected to the outer surfaces of the two first bevel gears 9.

[0016] Furthermore, the two bidirectional threaded rods 11 are respectively fixedly sleeved in the inner walls of the two second bevel gears 10, and the two bidirectional threaded rods 11 are rotatably connected in the inner wall of the fixed frame 5.

[0017] Furthermore, four movable nuts 12 are threaded onto the outer surfaces of two bidirectional threaded rods 11, and eight support rods 13 are rotatably connected to the outer surfaces of the four movable nuts 12.

[0018] Furthermore, the four movable plates 14 are rotatably connected to the ends of the eight support rods 13 away from the four movable nuts 12, and the four movable plates 14 are slidably connected to the eight sliding grooves 7 respectively.

[0019] Furthermore, the four LED mounting heads 15 are respectively fixedly mounted on the opposite sides of the four movable plates 14.

[0020] Furthermore, four vacuum nozzles 16 are respectively disposed on the lower surface of the four LED bead mounting heads 15; In this adjustable-spacing LED chip bead arrangement device, after the hydraulic unit 3 is activated, the hydraulic rod 4 extends and retracts along the inner wall of the hydraulic unit 3, driving the fixed frame 5 and the motor 6, fixed roller 8, and LED bead placement head 15 below to descend until the vacuum nozzle 16 reaches the appropriate material picking or placement height. Conversely, the hydraulic rod 4 retracts, driving the entire device to rise and complete the height adjustment. The motor 6 then activates, and its output drives the fixed roller 8 to rotate. The fixed roller 8 drives the two first bevel gears 9 on its outer surface to rotate synchronously. The first bevel gears 9 mesh with the second bevel gear 10, converting the horizontal rotational motion into vertical rotation, driving the bidirectional threaded rod 11 to rotate. When the bidirectional threaded rod 11 rotates, the movable nut 12 on its outer surface moves axially along the threaded rod due to the thread action. Two movable nuts 12 on the same bidirectional threaded rod 11 move in opposite directions, such as one moving to the left and the other to the right. The movable nuts 12 drive the support rod 13 to rotate, and the support rod 13 pushes or pulls the movable plate 14 to slide along the slide groove 7. Due to the restriction of the slide groove 7, the movable plate 14 only makes a straight line movement in the horizontal direction. The four movable plates 14 drive the vacuum nozzles 16 to move synchronously through the LED bead mounting head 15, so as to realize the spacing adjustment between adjacent vacuum nozzles 16. For example, the forward rotation time of the bidirectional threaded rod 11 increases and the reverse rotation time decreases. After the spacing and height are adjusted, the vacuum nozzles 16 grab the LED beads with negative pressure. With the cooperation of the hydraulic rod 4 and the movable plate 14, the LED beads are accurately mounted to the designated position to complete one mounting cycle. This adjustable-spacing LED chip bead arrangement equipment uses a motor 6 to drive a fixed roller 8 to rotate. This rotation, via a first bevel gear 9 and a second bevel gear 10, causes a bidirectional threaded rod 11 to rotate, which in turn moves a movable nut 12 in the opposite direction. This, in turn, pushes a movable plate 14 along a slide groove 7 via a support rod 13, allowing the four vacuum nozzles 16 to adjust their spacing synchronously. This linkage structure ensures consistent spacing adjustment, accurately matching the arrangement requirements of different LED bead specifications, and improving placement accuracy and efficiency. Furthermore, a hydraulic actuator 3 drives a hydraulic rod 4 to extend and retract, raising and lowering the fixed frame 5, the motor 6 below, the fixed roller 8, and the LED bead placement head 15. This quickly allows the vacuum nozzles 16 to reach the appropriate material picking or placement height. This structure flexibly adapts to different height operating requirements, reducing adjustment time and laying the foundation for subsequent accurate placement, thus enhancing the overall equipment's adaptability to various working conditions.

[0021] Structural Description: Placement machine 1: As the core equipment, it provides a stable working platform for the entire LED bead arrangement process. The storage slot 2 opened on its inner wall is used to install key components such as hydraulic device 3, ensuring that each mechanism can operate in an orderly manner and complete the task of precise arrangement of LED chip beads.

[0022] Storage slot 2: Located on the inner wall of mounting machine 1, its main function is to provide installation space for hydraulic unit 3, and to protect and support hydraulic unit 3, ensuring that hydraulic unit 3 remains stable during operation, thereby ensuring the normal operation of the entire adjustment mechanism.

[0023] Hydraulic unit 3: It is fixedly installed on the inner wall of the storage slot 2. It controls the extension and retraction of the hydraulic rod 4 through the hydraulic transmission principle to provide vertical power to the equipment, so that the fixed frame 5 and the LED bead mounting head 15 below can move up and down to meet the mounting requirements at different heights.

[0024] Hydraulic rod 4: It is slidably sleeved on the inner wall of hydraulic device 3 and performs telescopic movement under the action of hydraulic device 3. Its lower end is connected to fixed frame 5, which transmits the power generated by hydraulic device 3 to fixed frame 5, thereby driving fixed frame 5 and related components to achieve vertical position adjustment.

[0025] Fixed frame 5: Supported by two hydraulic rods 4, it provides a mounting base for components such as motor 6 and bidirectional threaded rod 11, ensuring that each component maintains a relatively stable positional relationship during operation. At the same time, it provides a track for the sliding of the moving plate 14 through the opened slide groove 7.

[0026] Motor 6: Fixed on the right surface of the fixed frame 5, it provides power for the entire adjustment mechanism. Its output end is connected to the fixed roller 8. By rotating, it drives the fixed roller 8 to rotate, which in turn drives the first bevel gear 9, the second bevel gear 10 and the bidirectional threaded rod 11 to rotate, thereby realizing the spacing adjustment of the lamp bead mounting head 15.

[0027] Slide 7: Eight slides are provided on the opposite sides of the two horizontal plates of the fixed frame 5. They provide a precise track for the sliding of the movable plate 14, ensuring that the movable plate 14 can move smoothly and accurately under the push of the support rod 13, thereby realizing the spacing adjustment of the lamp bead mounting head 15.

[0028] Fixed roller 8: Rotatably connected to the inner wall of the horizontal plate of the fixed frame 5, and fixed at the right end to the output end of the motor 6. When the motor 6 works, the fixed roller 8 rotates accordingly and transmits power to the two first bevel gears 9 fixedly sleeved on its outer surface, so that they rotate synchronously.

[0029] The first bevel gear 9 is fixedly sleeved on the outer surface of the fixed roller 8 and meshes with the second bevel gear 10. When the fixed roller 8 rotates, the first bevel gear 9 rotates accordingly and drives the second bevel gear 10, which meshes with it, to rotate, thereby realizing the vertical transmission of power and changing the direction of force transmission.

[0030] The second bevel gear 10 meshes with the first bevel gear 9, and its inner wall is fixedly fitted with a bidirectional threaded rod 11. Under the drive of the first bevel gear 9, the second bevel gear 10 rotates, thereby driving the bidirectional threaded rod 11 to rotate on the inner wall of the fixed frame 5, providing power for the movement of the movable nut 12.

[0031] Bidirectional threaded rod 11: Rotatably connected to the inner wall of the fixed frame 5, with a movable nut 12 threaded on its outer surface. When the bidirectional threaded rod 11 rotates under the drive of the second bevel gear 10, due to the characteristics of its bidirectional thread, the movable nut 12 on it will move in the opposite direction, thereby realizing the spacing adjustment of the LED bead mounting head 15.

[0032] Movable nut 12: It is threaded on the outer surface of the bidirectional threaded rod 11, and the outer surface is rotatably connected to the support rod 13. When the bidirectional threaded rod 11 rotates, the movable nut 12 moves along the rod and pushes the movable plate 14 to slide in the slide groove 7 through the support rod 13, so as to finally realize the position adjustment of the lamp bead mounting head 15.

[0033] Support rod 13: One end is rotatably connected to the outer surface of the movable nut 12, and the other end is rotatably connected to the movable plate 14. When the movable nut 12 moves under the action of the bidirectional threaded rod 11, the support rod 13 moves accordingly, converting the linear motion of the movable nut 12 into the sliding motion of the movable plate 14 in the slide groove 7, thus playing the role of force transmission and conversion.

[0034] Movable plate 14: It is slidably connected to the slide groove 7, and the lower end is fixedly installed with the LED bead mounting head 15. Under the push of the support rod 13, the movable plate 14 slides along the slide groove 7, thereby driving the LED bead mounting head 15 to move, realizing the adjustment of the spacing between the LED bead mounting heads 15 to adapt to different mounting requirements.

[0035] LED bead placement head 15: Fixedly installed on the opposite side of the moving plate 14, with a vacuum nozzle 16 on the lower surface. It is the component that directly performs the LED bead placement task. The vacuum nozzle 16 adsorbs the LED beads and accurately places them in the designated position under the control of the equipment.

[0036] Vacuum nozzle 16: Located on the lower surface of LED bead placement head 15, it uses the principle of vacuum adsorption to adsorb LED beads. During the placement process, vacuum nozzle 16 ensures stable gripping and precise placement of LED beads, and is a key component to ensure placement quality and efficiency.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
