Description

Technical Field

[0001] This utility model relates to the field of screw assembly, specifically a screw assembly device for manufacturing power distributors. Background Technology

[0002] In the field of power electronic equipment manufacturing, power distributors, as core components, are responsible for distributing input power to multiple output ports on demand. They are widely used in data centers, communication base stations, industrial automation equipment, and other scenarios. Their structure typically consists of a metal casing, printed circuit board (PCB), conductive copper busbars, terminals, and fasteners (such as screws). Screws, as critical connectors, not only secure the casing to internal components but also ensure reliable electrical connections between conductive parts. Their assembly quality directly affects the mechanical stability, electrical safety, and long-term operational reliability of the power distributor.

[0003] To address these needs, the industry has gradually developed modular screw assembly devices that use CCD cameras to identify hole coordinates, enabling automated screw gripping, positioning, and tightening. For example, the Chinese authorized patent (CN 213829392 U, "A Wooden Leg Screw Assembly") includes a frame, a chuck mechanism, a drilling machine, and a screw-assembly machine. The chuck mechanism includes a motor, a rotating shaft, a base, and a chuck parallel to the base. The worker places the wooden leg into the chuck, where the chuck and base work together to hold it. The motor drives the rotating shaft, base, and chuck to rotate synchronously at a set angle, causing the wooden leg to rotate under the drilling machine. The drilling machine then completes the drilling process. The motor drives the rotating shaft to rotate until the wooden leg is directly under the screw-assembly machine, where the screw-assembly machine completes the screw assembly process. The process continues until the wooden leg returns to its original position, thus efficiently completing the drilling and screw assembly processes for the wooden leg.

[0004] Although the aforementioned prior art has the function of screw assembly, it can only assemble a single screw at a time, and cannot assemble two screws at the same time. Furthermore, it cannot adjust the spacing between the two screws according to the hole position to achieve the joint assembly of two screws. Utility Model Content

[0010] Preferably, a third drive motor is installed at the middle of the upper end of the supporting horizontal plate, and a central rotating shaft is installed at the lower end of the supporting horizontal plate along the output shaft end of the third drive motor.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please see Figures 1-6 This utility model provides an embodiment of a screw assembly device for manufacturing a power distributor, comprising a lower mounting platform 1 and a lower screwdriver bit 33. The lower mounting platform 1 serves as the basic support structure for the entire device, providing a stable mounting platform for other components. A fixed bracket 2 is welded and fixed to both sides of the lower mounting platform 1, serving a reinforcing and supporting function. A first drive motor 3 is mounted on one side of the upper end of the fixed bracket 2, providing power to drive a rotating gear 4. When the first drive motor 3 starts, the rotating gear 4 rotates accordingly, and through its meshing relationship with a driven rotating gear 5, drives the driven rotating gear 5 to rotate synchronously. A rotating disk 6 connected to the upper end of the driven rotating gear 5 is rotatably connected to the lower mounting platform 1 via bearings, allowing the rotating disk 6 to rotate smoothly, providing power transmission for the subsequent horizontal movement of the screwdriver bit, ensuring that the screwdriver bit accurately reaches the designated position.

[0021] A fixed frame 7 is centrally fixed at the upper end of the rotating disk 6. A second drive motor 8 is mounted on the upper end of the fixed frame 7. A drive threaded rod 9 is installed inside the fixed frame 7 along the output shaft end of the second drive motor 8. A lifting column 10 is threadedly connected to the outside of the drive threaded rod 9. A rear horizontal plate 11 is fixed to the outside of the lifting column 10. The rear horizontal plate 11 slides along the outside of the fixed frame 7. Since the front end connection structure of the rear horizontal plate 11 is a cantilever structure, a counterweight structure can be added to the rear end of the rear horizontal plate 11 to balance the force (the counterweight structure is set with different shapes and specifications according to the actual situation, and is not specifically shown in the figure). When the second drive motor 8 drives the drive threaded rod 9 to rotate, the lifting column 10 will move linearly along the thread direction of the drive threaded rod 9, thereby driving the structure connected to the front end of the lifting column 10 to move upward or downward together. This allows the screwdriver bit 33 to move accurately in the vertical direction, realizing the height adjustment during screw loading and installation, and greatly improving the flexibility and accuracy of screw assembly.

[0022] A supporting horizontal plate 12 is located at the front end of the rear horizontal plate 11 and is integrally formed with the rear horizontal plate 11. Fixed vertical plates 14 are welded and fixed to both sides of the supporting horizontal plate 12. A lower fixed housing 15 is welded and fixed between the two fixed vertical plates 14 along the lower end of the supporting horizontal plate 12. A limiting groove 16 is formed inside the lower fixed housing 15, and an adjustment assembly unit 18 is connected to the lower fixed housing 15. The adjustment assembly unit 18 includes two symmetrically arranged limiting sliders 31. The limiting sliders 31 slide along the limiting groove 16, ensuring the stability of the limiting sliders 31 during sliding and providing a reliable guarantee for the accurate positioning of subsequent screwdriver bits. A second rotating shaft 28 is connected through the limiting slider 31, and the second rotating shaft 28 is rotatably connected to the limiting slider 31. A second lower linkage rod 30 is rotatably connected to the outside of the second rotating shaft 28 along the upper end of the lower fixed housing 15, and a second upper linkage rod 22 is rotatably connected to the outside of the second rotating shaft 28 along the upper end of the second lower linkage rod 30.

[0023] The adjustment assembly unit 18 also includes a driven gear 19. A fixing sleeve 20 is centrally fixed to the lower end of the driven gear 19. A first upper linkage rod 21 is fixed to the lower end of the fixing sleeve 20. A first rotating shaft 27 is rotatably connected to both ends of the first upper linkage rod 21. The upper end of the first rotating shaft 27 is rotatably connected to the driven gear 19. The lower end of the first rotating shaft 27 passes through the other end of the second upper linkage rod 22 and the other end of the second lower linkage rod 30 and extends downwards. The lowest points of the two first rotating shafts 27 are connected to a first lower linkage rod 29. The first lower linkage rod 29, the second lower linkage rod 30, and the second upper linkage rod 22 are all rotatably connected to the first rotating shaft 27. This linkage structure enables the various components to work collaboratively, achieving screwdriver bit position adjustment through transmission, providing strong support for precise screwdriver bit positioning and screw installation.

[0024] The lower fixed housing 15 has an upper slot 37 and a lower slot 17 on its upper and lower end faces, respectively. The second rotating shaft 28 slides along the upper slot 37 and the lower slot 17. This double-slot limiting design further restricts the sliding range of the second rotating shaft 28, ensuring that it moves within a specified trajectory and reducing screw installation problems caused by positional deviations. A lower limiting plate 32 is fixed to the lower end of the second rotating shaft 28, and a lower screwdriver bit 33 is fixed to the lower end of the lower limiting plate 32. The lower screwdriver bit 33 is magnetic. By magnetizing the lower screwdriver bit 33 or embedding a magnetic structure inside the lower screwdriver bit 33, the lower screwdriver bit 33 becomes magnetic, thereby attracting screws. The magnetic design of the lower screwdriver bit 33 enables it to easily attract screws, allowing for quick and accurate screw attraction and fixation during screw loading.

[0025] A front horizontal plate 13 is integrally connected to the front end of the supporting horizontal plate 12. A fourth drive motor 35 is installed on the upper end of the front horizontal plate 13, and a drive pinion 36 is installed on the lower end of the front horizontal plate 13 along the output shaft of the fourth drive motor 35. The drive pinion 36 meshes with the driven large gear 19. When the fourth drive motor 35 starts, the drive pinion 36 rotates, driving the driven large gear 19 to rotate through its meshing connection with the driven large gear 19. This, in turn, drives the first upper linkage rod 21, which is fixed to the driven large gear 19 by the fixed sleeve 20, to rotate. Since the first upper linkage rod 21 and the second upper linkage rod 22 are rotatably connected by the first rotating shaft 27, and the second rotating shaft 28, which is rotatably connected to the other end of the second upper linkage rod 22, is limited by the upper slot 37 on the lower fixed housing 15, the angle between the first upper linkage rod 21 and the second upper linkage rod 22 is adjusted. The second rotating shaft 28 slides along the upper slot 37, causing the distance between the two lower screwdriver bits 33 to be adjusted to match the mounting hole position of the power distributor.

[0026] A first rotating pinion 24 connects the first upper linkage 21 and the first lower linkage 29. A second rotating pinion 25 is fixed externally to the first rotating shaft 27, and a third rotating pinion 26 is fixed externally to the second rotating shaft 28. The first rotating pinion 24, the second rotating pinion 25, and the third rotating pinion 26 are located on the same horizontal plane and are meshed together. The meshing design of the pinions makes the rotational transmission smoother, ensuring the coordinated work between the various components and realizing the rotational control of the screwdriver bit.

[0027] A third drive motor 34 is installed at the middle of the upper end of the supporting horizontal plate 12. A central rotating shaft 23 is installed at the lower end of the supporting horizontal plate 12 along the output shaft of the third drive motor 34. The central rotating shaft 23 passes through the fixed sleeve 20, the first upper linkage rod 21, the first rotating pinion 24, and the first lower linkage rod 29 in sequence. The central rotating shaft 23 is rotatably connected to the fixed sleeve 20, the first upper linkage rod 21, and the first lower linkage rod 29. The central rotating shaft 23 is fixed to the first rotating pinion 24. When the third drive motor 34 drives the central rotating shaft 23 to rotate, it drives the first rotating pinion 24 connected to the central rotating shaft 23 to rotate synchronously. Due to the meshing relationship between the first rotating pinion 24, the second rotating pinion 25, and the third rotating pinion 26, the third rotating pinion 26 rotates, driving the second rotating shaft 28, the lower limit plate 32, and the lower screwdriver bit 33 connected to the third rotating pinion 26 to rotate synchronously.

[0028] Working principle: The second drive motor 8 drives the drive threaded rod 9 to rotate, causing the lifting column 10 and its front connecting structure to move upwards together, thus moving the lower screwdriver bit 33 upwards. Simultaneously, the first drive motor 3 drives the drive rotating gear 4 to rotate, and through the meshing relationship between the drive rotating gear 4 and the driven rotating gear 5, the driven rotating gear 5 rotates synchronously. The upper connecting structure of the rotating disk 6 rotates backwards, causing the lower screwdriver bit 33 to move backwards, reaching the upper end of the screw disk. The second drive motor 8 then drives the drive threaded rod 9 to rotate in the opposite direction, causing the lower screwdriver bit 33 to move downwards. The lower screwdriver bit 33 enters the cross groove of the screw, attracting the screw through its own magnetism.

[0029] Then the second drive motor 8 drives the drive thread rod 9 to rotate, and the lower screwdriver bit 33 is driven to move upward. At the same time, the first drive motor 3 drives the drive gear 4 to rotate in the opposite direction, so that the lower screwdriver bit 33 reaches the upper end of the hole of the power distributor.

[0030] In conjunction with the CCD camera to identify the hole position coordinates, the fourth drive motor 35 drives the drive pinion 36 to rotate. Through the meshing connection between the drive pinion 36 and the driven large gear 19, the driven large gear 19 is driven to rotate, thereby driving the first upper linkage rod 21, which is fixed to the driven large gear 19 through the fixed sleeve 20, to rotate. Since the first upper linkage rod 21 and the second upper linkage rod 22 are rotatably connected through the first rotating shaft 27, the second rotating shaft 28, which is rotatably connected to the other end of the second upper linkage rod 22, is limited by the upper slot 37 on the lower fixed housing 15, so that the angle between the first upper linkage rod 21 and the second upper linkage rod 22 is adjusted. The second rotating shaft 28 slides along the upper slot 37, thereby adjusting the distance between the two lower screwdriver bits 33 to match the installation hole position.

[0031] The third drive motor 34 drives the central rotating shaft 23 to rotate, thereby causing the first rotating pinion 24 connected to the central rotating shaft 23 to rotate synchronously. Due to the meshing relationship between the first rotating pinion 24, the second rotating pinion 25, and the third rotating pinion 26 (even if the angle between the first upper linkage rod 21 and the second upper linkage rod 22 is adjusted by the drive, it will not affect the meshing relationship of the three), the third rotating pinion 26 rotates, causing the second rotating shaft 28, the lower limit plate 32, and the lower screwdriver bit 33 connected to the third rotating pinion 26 to rotate synchronously. The second drive motor 8 synchronously drives the threaded rod 9 to rotate at a small angle, realizing the downward rotation of the lower screwdriver bit 33 and realizing the assembly of the screw.

[0032] The screw assembly device then repeats the feeding process, while the external adjustment fixture adjusts the position of the power distributor, so that the mounting hole of the power distributor moves to the lower end of the screw assembly device. The screw installation work can be completed by continuing to adjust the distance between the two lower screwdriver bits 33 to match the mounting hole of the power distributor.

[0033] 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.
