Description

Technical Field

[0001] This invention relates to the field of connector technology, and more specifically to an automated connector assembly device. Background Technology

[0002] A connector is a component used to achieve electrical transmission connections between circuits, electronic devices, etc. It is widely used in electronic devices such as computers, servers, and network storage devices. As one of the important types of connectors, electrical connectors are mainly used for data transmission interfaces of devices such as hard drives. They play a key role in ensuring stable signal transmission in electronic devices. With the development of electronic technology, the performance and quality of electrical connectors have an increasingly significant impact on the overall performance of electronic devices, and their assembly process has become increasingly complex. Therefore, specialized automated assembly equipment is needed to ensure assembly accuracy and efficiency.

[0003] However, existing automated assembly equipment for electrical connectors suffers from long assembly times and reduced efficiency when facing the trend of miniaturization, refinement, and diversification of electronic devices. The existing equipment also has poor flexibility and compatibility, making it difficult to adapt to the rapid switching of different specifications and types of electrical connectors. Each time the product model is changed, a lot of time is often required to adjust the equipment parameters and change the tooling fixtures, which seriously affects production efficiency and increases production costs. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the present invention provides an automatic assembly device for connectors to solve the above problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic assembly device for connectors, comprising a connecting frame, a PLC programmable controller fixedly connected to the left side of the connecting frame, a power housing fixedly connected to the upper surface of the connecting frame, a drive unit disposed inside the power housing, a first multi-stage telescopic cylinder disposed at the bottom of the drive unit, a switching unit fixedly connected to the drive unit through the first multi-stage telescopic cylinder, four connecting posts fixedly connected to the upper surface of the connecting frame, and a conveying unit fixedly connected to the connecting frame through the four connecting posts.

[0006] The beneficial effects of this invention are as follows:

[0007] 1. This invention, through a drive unit, pressing unit, switching unit, and conveying unit, effectively overcomes the shortcomings of existing automatic assembly equipment for electrical connectors, significantly improving assembly efficiency and the flexibility and compatibility of the equipment. A dual-output shaft servo motor, via a stabilizing plate, drives a transmission plate and a circulating housing downwards to perform connector assembly. Its upper output end drives a first bevel gear to rotate, and a second bevel gear meshing with the first bevel gear drives a transmission shaft and transmission gear to rotate. The transmission gear meshes with a gear plate, ensuring stable movement of the dual-output shaft servo motor within the power housing. The first stepper motor of the pressing unit controls the rotation of the pressure column, enabling spiral assembly of connectors and splicing parts, allowing the connectors to be directly rotated and connected to the splicing parts. If the connector does not require spiral assembly, the first stepper motor does not need to be started, increasing the versatility of installation requirements. The second stepper motor drives the transmission unit, moving the first and second conveying gears to achieve rapid conveying of connectors and splicing parts, greatly shortening assembly time, improving assembly efficiency, and avoiding the problem of low production efficiency due to long assembly times.

[0008] 2. This invention features five reset ports on the switching plate, each containing a second multi-stage telescopic cylinder and a rectangular multi-stage telescopic shell. Each reset port also houses different types of adjustment units, facilitating the installation of various connectors. A first reset spring within the second multi-stage telescopic cylinder allows the limiting plate to flexibly switch between different reset ports, adapting to the assembly requirements of different specifications and types of electrical connectors. Utilizing multiple second and third reset springs, along with the first and second compression cylinders, as well as the first and second extrusion plates, it can adaptively clamp connectors according to their dimensions. The inclusion of first splicing joints, second splicing joints, and second connectors facilitates docking with different connector components. The PLC programmable controller enables precise collaboration among the various structures, allowing for rapid switching between different specifications and types of electrical connectors. This avoids the significant time required to adjust equipment parameters and change tooling fixtures each time a product model is changed, enhancing the flexibility and compatibility of the equipment.

[0025] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0026] Example:

[0027] Please see Figures 1 to 15 An automatic assembly device for connectors includes a connector frame 1. A PLC programmable controller 5 is fixedly connected to the left side of the connector frame 1. A power housing 2 is fixedly connected to the upper surface of the connector frame 1. A drive unit is arranged inside the power housing 2. A first multi-stage telescopic cylinder 3 is arranged at the bottom of the drive unit. A switching unit is fixedly connected to the drive unit through the first multi-stage telescopic cylinder 3. Four connecting posts 9 are fixedly connected to the upper surface of the connector frame 1. A conveying unit is fixedly connected to the connector frame 1 through the four connecting posts 9.

[0028] Working principle: After the equipment is started, the PLC programmable controller 5 receives external instructions and sends control signals to drive the dual-axis servo motor 22 to run. The stabilizing plate 25 of the dual-axis servo motor 22 slides in the stabilizing groove 27 on the inner wall of the power housing 2, ensuring the smooth operation of the motor. The dual-axis servo motor 22 drives the transmission plate 19 through the stabilizing plate 25, which in turn causes the circulation housing 20 to slide in the balance frame 31, realizing the stable lifting and lowering of the pressing unit. This solves the problem of unstable assembly action in traditional assembly equipment and initially establishes the power and motion foundation for assembly. The connector can be quickly assembled through the drive unit, switching unit and conveying unit.

[0029] Please see Figures 1 to 15 The drive unit includes a dual-axis servo motor 22 fixedly connected to the top of the first multi-stage telescopic cylinder 3. Two stabilizing slots 27 are opened on the inner wall of the power housing 2. Four stabilizing plates 25 are fixedly connected to the outer surface of the dual-axis servo motor 22. The interior of each stabilizing slot 27 is slidably connected to the outer surface of the two stabilizing plates 25. A pressing unit is fixedly connected to the dual-axis servo motor 22 through the two stabilizing plates 25. A first bevel gear 24 is fixedly connected to the outer surface of the output end of the dual-axis servo motor 22. A limit post 26 is fixedly connected to the output end of the dual-axis servo motor 22. A second bevel gear 62 meshes with the outer surface of the first bevel gear 24. A transmission shaft 29 is fixedly connected to the inner wall of the second bevel gear 62. A transmission gear 28 is fixedly connected to one end of the transmission shaft 29. A toothed plate 21 is fixedly connected to the inner wall of the power housing 2. The outer surface of the transmission gear 28 meshes with the outer surface of the toothed plate 21. A PLC programmable controller 5 is electrically connected to the dual-axis servo motor 22 through wires.

[0030] Working principle: The dual-axis servo motor 22 operates. The dual-axis servo motor 22 is a Panasonic MINASA6 series dual-axis servo motor with high-precision position control. When used with Panasonic servo drivers, it can achieve micron-level positioning accuracy. Its output drives the first bevel gear 24 to rotate. The first bevel gear 24 meshes with the second bevel gear 62, which in turn drives the transmission shaft 29 to rotate. The transmission gear 28 on the transmission shaft 29 meshes with the toothed plate 21 on the inner wall of the power housing 2, causing the dual-axis servo motor 22 to move smoothly within the power housing 2. At the same time, the dual-axis servo motor 22 drives the circulation housing 20 of the pressing unit to move downward through the stabilizing plate 25. In this process, the precise gear transmission ensures the accuracy of the movement of the dual-axis servo motor 22 and the action of the pressing unit, avoiding assembly position deviations and improving assembly accuracy.

[0031] Please see Figures 1 to 15The pressing unit includes a balance frame 31 fixed to the inner top wall of the connecting frame 1. A circulation shell 20 is slidably connected inside the balance frame 31. A sliding opening 18 is provided on the right side of the power shell 2. A transmission plate 19 is fixedly connected to the upper surface of the circulation shell 20. The left end of the transmission plate 19 passes through the sliding opening 18 and extends into the interior of the sliding opening 18. The left side of the transmission plate 19 is fixedly connected to the right side of two of the stabilizing plates 25. A first stepper motor 44 and a first bearing 42 are fixedly connected to the inner wall of the circulation shell 20. The output end of the first stepper motor 44 is fixed. A connecting shaft 43 is connected to the inner ring of the first bearing 42, and a pressure column 17 is fixedly connected to it. The top end of the pressure column 17 is fixedly connected to the bottom end of the connecting shaft 43. A second bearing 36 is fixedly connected to the outer surface of the bottom end of the pressure column 17. A limit plate 33 is fixedly connected to the outer surface of the second bearing 36. A prism block 64 is snapped into the inside of the pressure column 17. A top plate 40 is fixedly connected to the bottom end of the prism block 64. An adjustment unit is fixedly connected to the pressure column 17 through the top plate 40. A PLC programmable controller 5 is electrically connected to the first stepper motor 44 through wires.

[0032] Working principle: When the circulating shell 20 descends, the transmission plate 19 moves downward through the stabilizing plate 25, and the circulating shell 20 descends through the transmission plate 19. It can move downward stably with the connecting frame 1 and the balance frame 31. The circulating shell 20 can drive the pressure column 17 to move directly downward and engage with the prism block 64, which is convenient for engaging with the top plate 40. The first stepper motor 44 is started under the control of the PLC programmable controller 5. Its output end drives the pressure column 17 to rotate through the connecting shaft 43. The pressure column 17 engages with the top plate 40 through the prism block 64 and drives the top plate 40 to rotate, thereby causing the adjusting shell 35 of the adjusting unit to rotate. If the connector needs to be screwed together, the screw connection between the connector and the splicing part is achieved by rotating the adjusting shell 35. If screw assembly is not required, the first stepper motor 44 can be turned off. This adjustable assembly method meets diverse assembly needs and solves the problem of the single assembly method of traditional equipment.

[0033] Please see Figures 1 to 15 The adjustment unit includes an adjustment shell 35 fixed to the bottom surface of the top plate 40. Four telescopic balance cylinders 47 are fixedly connected to the inner wall of the adjustment shell 35. An adjustment plate 46 is fixedly connected to one end of the four telescopic balance cylinders 47. A third bearing 45 is fixedly connected to the outer surface of the adjustment plate 46. An adjustment bolt 38 is threadedly connected to the inner wall of the adjustment shell 35. The outer surface of one end of the adjustment bolt 38 is fixedly connected to the inner ring of the third bearing 45. A first connector B1 is snapped into the inside of the adjustment shell 35. A bearing seat 30 is fixedly connected to the upper surface of the dual-output shaft servo motor 22. The inner ring of the bearing seat 30 is fixedly connected to the outer surface of the drive shaft 29.

[0034] Working principle: When it is necessary to adjust the assembly force or position, rotate the adjusting bolt 38. The adjusting bolt 38 can move spirally inside the adjusting housing 35. Then, the adjusting bolt 38 drives the adjusting plate 46 to move through the third bearing 45. The adjusting plate 46 drives the balance cylinder 47 to extend and retract. The balance cylinder 47 ensures the stability of the movement of the adjusting plate 46, thereby adjusting the position of the first connector B1 inside the adjusting housing 35. This ensures that the first connector B1 can accurately mate with different connector components. At the same time, the bearing seat 30 on the dual-axis servo motor 22 supports the transmission shaft 29, ensuring the stable operation of the transmission system and improving the adaptability of the equipment to the assembly of different connectors.

[0035] Please see Figures 1 to 15 The switching unit includes an arc-shaped shell 4 fixed to the inner wall of the connecting frame 1. An annular ring 16 is slidably connected inside the arc-shaped shell 4. A switching disk 15 is fixedly connected to the inner wall of the annular ring 16. A fourth bearing 14 is fixedly connected to the upper surface of the switching disk 15. The inner ring of the fourth bearing 14 is fixedly connected to the bottom end of the first multi-stage telescopic cylinder 3. Five reset ports 13 are opened on the upper surface of the switching disk 15. A second multi-stage telescopic cylinder 32 and a rectangular multi-stage telescopic shell 37 are fixedly connected to the inner wall of each reset port 13. The bottom end of each second multi-stage telescopic cylinder 32 and the rectangular multi-stage telescopic shell 37 are connected to each other. The bottom surfaces of all the components are fixedly connected to limit plates 39. The bottom surface of the limit plate 33 is in contact with the upper surfaces of four of the limit plates 39. The bottom ends of the pressure columns 17 all penetrate to the bottom of one of the reset ports 13. The outer surface of the limit plate 33 is in contact with the outer surfaces of four of the second multi-stage telescopic cylinders 32 and the outer surface of the rectangular multi-stage telescopic shell 37. The inner wall of each second multi-stage telescopic cylinder 32 is fixedly connected to a first reset spring 41. The outer surface of the arc-shaped shell 4 is fixedly connected to two stabilizers 6. One end of each stabilizer 6 is fixedly connected to the front of the connecting frame 1.

[0036] Working principle: The dual-axis servo motor 22 drives the switching disk 15 to rotate through the first multi-stage telescopic cylinder 3. The reset port 13 on the switching disk 15 rotates accordingly. When it is necessary to switch the first connector B1 model, the first reset spring 41 in the second multi-stage telescopic cylinder 32 pushes the limit disk 33, so that the pressure column 17 docks with the adjustment unit below the different reset ports 13. The arc-shaped shell 4 and the stabilizer 6 ensure the stable rotation of the ring 16 and the switching disk 15, realizing the rapid switching of different connector models. This solves the problem that traditional equipment is difficult to adapt to the assembly of multiple connectors. Each reset port 13 is equipped with an adjustment unit of a different model to adapt to different connector models B1, which facilitates switching and assembly, thereby increasing compatibility and assembly efficiency.

[0037] Please see Figures 1 to 15The conveying unit includes a first conveying shell 10 fixedly connected to the top of four connecting columns 9. Four supporting feet 49 are fixedly connected to the upper surface of the first conveying shell 10. The top of the four supporting feet 49 are fixedly connected to a second conveying shell 11. A clamping unit and a transmission unit are jointly arranged inside the first conveying shell 10 and the second conveying shell 11. A first conveying gear 8 and a second conveying gear 7 are slidably connected inside the first conveying shell 10 and the second conveying shell 11, respectively. An electric telescopic rod 34 is fixedly connected to the inner bottom wall of the connecting frame 1. A first splicing joint A1 is fixedly connected to the telescopic end of the electric telescopic rod 34. Multiple second splicing joints A2 and multiple second connecting heads B2 are respectively arranged inside the first conveying gear 8 and the second conveying gear 7. A first infrared ranging sensor 12 is fixedly connected to the upper surface of the second conveying shell 11. Five second infrared ranging sensors 48 are fixedly connected to the bottom surface of the switching disk 15. A PLC programmable controller 5 is electrically connected to the electric telescopic rod 34, the first infrared ranging sensor 12 and the second infrared ranging sensor 48 through wires.

[0038] Working principle: When the equipment starts working, the PLC programmable controller 5 sends a control signal to the electric telescopic rod 34 according to the preset program or external instructions. The electric telescopic rod 34 begins to extend and retract, and its extension end drives the first splicing joint A1 to move. The first conveying shell 10 is connected to the main body of the equipment through four connecting columns 9, ensuring the stability of the structure. The four support feet 49 firmly support the second conveying shell 11 above the first conveying shell 10, providing a stable channel for the conveying of the connector components. The first conveying gear 8 and the second conveying gear 7 slide in the first conveying shell 10 and the second conveying shell 11 respectively, and multiple [equipment / features] are respectively set on them. The second splice A2 and multiple second connectors B2, the first infrared ranging sensor 12 and the second infrared ranging sensor 48 can detect the rotation angle of the switching disk 15, preventing errors in the rotation of the switching disk 15 from causing insufficient assembly accuracy, realizing the initial positioning and transport preparation of the connector components, and solving the problem of inaccurate positioning of transport components in traditional equipment. The first infrared ranging sensor 12 and the second infrared ranging sensor 48 are Panasonic VZ series pyroelectric infrared sensors EKMC1603111, which can sense the position and movement status of the human body or object by detecting the infrared rays emitted by the human body or object, thereby realizing the positioning function.

[0039] Please see Figures 1 to 15The clamping unit includes multiple second return springs 55 and third return springs 63 fixedly connected to the inner walls of the first conveying shell 10 and the second conveying shell 11 in opposite directions. Multiple first compression cylinders 53 and multiple second compression cylinders 54 in opposite directions are slidably connected inside the first conveying shell 10 and the second conveying shell 11. One end of each second return spring 55 and one end of each third return spring 63 are fixedly connected to the inner walls of the first compression cylinder 53 and the second compression cylinder 54, respectively. A first extrusion plate 52 and a second extrusion plate 51 are fixedly connected to the inner wall of one end of each first compression cylinder 53 and one end of each second compression cylinder 54. The outer surface of the first splice A1 is in contact with the side of two of the first extrusion plates 52 that are close to each other. The outer surface of each second splice A2 is in contact with the side of each of the other two first extrusion plates 52 that are close to each other. The outer surface of each second connector B2 is in contact with the side of two second extrusion plates 51 that are close to each other. The outer surface of the first connector B1 is engaged with the inside of the first splice A1.

[0040] Working principle: The electric telescopic rod 34 pushes the first splice A1 to move. The first splice A1 contacts and squeezes the two first extrusion plates 52 inside the first conveying shell 10. After being squeezed, the first extrusion plates 52 push the first compression cylinder 53 to slide, causing the second return spring 55 to be compressed, generating elastic force. Moreover, because the first extrusion plates 52 are movable, different models of first splice A1 can be installed inside the first conveying shell 10. Similarly, the second splice A2 and the second connector B2 contact and squeeze the corresponding first extrusion plates 52 and 51 respectively, causing the corresponding second return spring 55 and third return spring 63 to be compressed. These elastic forces make the first extrusion plates 52 and 51 tightly clamp the connector components, ensuring the stability of the connector components during the conveying process. The first connector B1 is engaged with the first splice A1, further enhancing the stability of the connection and preventing the connector components from shaking or shifting during the conveying process.

[0041] Please see Figures 1 to 15The transmission unit includes a second stepper motor 50 fixedly connected to the upper surface of the second conveying shell 11. A fifth bearing 57 and a sixth bearing 61 are fixedly connected to the inner wall of the second conveying shell 11 and the inner wall of the first conveying shell 10, respectively. A seventh bearing 23 is fixedly connected to the inner bottom wall of the second conveying shell 11 and the inner bottom wall of the first conveying shell 10. A first rotating shaft 56 is fixedly connected to the inner ring of the fifth bearing 57. The top end of the first rotating shaft 56 is fixedly connected to the output end of the second stepper motor 50. The second rotating shaft 60 is fixedly connected to the inner ring of the sixth bearing 61. A first forward gear 58 and a second forward gear 59 are fixedly connected to the inner rings of the two seventh bearings 23, respectively. The top and bottom ends of the second rotating shaft 60 are fixedly connected to the bottom end of the first forward gear 58 and the top end of the second forward gear 59, respectively. The inner ring of the seventh bearing 23 is fixedly connected to the outer surface of the bottom end of the first forward gear 58. A PLC programmable controller 5 is electrically connected to the second stepper motor 50 through wires.

[0042] Working principle: The PLC programmable controller 5 sends a control signal to the second stepper motor 50, which starts and drives the first rotating shaft 56 to rotate. The first rotating shaft 56 rotates stably on the inner wall of the second conveying shell 11 through the fifth bearing 57. The first rotating shaft 56 drives the first forward gear 58 to rotate. The first forward gear 58 drives the second forward gear 59 to rotate through the second rotating shaft 60. The second rotating shaft 60 is stably supported by the sixth bearing 61 and the seventh bearing 23. The first forward gear 58 and the second forward gear 59 mesh with the first conveying gear frame 8 and the second conveying gear frame 7, respectively. Under the action of gear transmission, the first conveying gear frame 8 and the second conveying gear frame 7 move within the first conveying shell 10 and the second conveying shell 11, thereby realizing the rapid conveying of connectors and splice joints. This precise gear transmission structure ensures the stability and accuracy of the conveying and improves the assembly efficiency of connectors.

[0043] In summary, during operation, a PLC programmable controller 5 is installed on the left side of the connecting frame 1. The PLC programmable controller 5 receives external commands and sends control signals to drive the Panasonic MINASA 6 series dual-axis servo motor 22 located inside the power housing 2. This motor has high-precision position control capabilities, and in conjunction with Panasonic's servo driver, it can achieve micron-level positioning accuracy. The stabilizing plate 25 of the dual-axis servo motor 22 slides within the stabilizing groove 27 on the inner wall of the power housing 2, ensuring smooth motor operation. The stabilizing plate 25 drives the transmission plate 19, which in turn causes the circulation housing 20 to slide within the balance frame 31, achieving stable lifting and lowering of the pressing unit. When the dual-axis servo motor 22 is running, its output end drives the first bevel gear 24 to rotate. Gear 24 meshes with the second bevel gear 62, causing the second bevel gear 62 to drive the transmission shaft 29 to rotate. The transmission gear 28 on the transmission shaft 29 meshes with the toothed plate 21 on the inner wall of the power housing 2, causing the dual-output shaft servo motor 22 to move smoothly within the power housing 2. At the same time, it drives the circulation housing 20 of the pressing unit to move downward through the stabilizing plate 25. The precise gear transmission ensures the accuracy of the movement of the dual-output shaft servo motor 22 and the action of the pressing unit, avoiding assembly position deviations and improving assembly accuracy. When the circulation housing 20 descends, it drives the transmission plate 19 to move downward through the stabilizing plate 25, thereby driving the circulation housing 20 to descend. It moves downward steadily in conjunction with the connecting frame 1 and the balance frame 31. The circulation housing 20 drives the pressure column 17 to move downward and engage with the prismatic block 64, and with the top The plate 40 is snapped in place. Under the control of the PLC programmable controller 5, if the connector requires spiral assembly, the first stepper motor 44 starts, and its output end drives the pressure column 17 to rotate through the connecting shaft 43. The pressure column 17 drives the top plate 40 to rotate through the prismatic block 64, thereby causing the adjusting shell 35 of the adjusting unit to rotate, realizing the spiral connection between the connector and the splicing part. If spiral assembly is not required, the first stepper motor 44 is turned off to meet diverse assembly needs. When different models of connectors of the same product need to be used, the adjusting bolt 38 is rotated. The adjusting bolt 38 moves spirally inside the adjusting shell 35, driving the adjusting plate 46 to move through the third bearing 45. The adjusting plate 46 drives the telescopic balance cylinder 47 to extend and retract, ensuring the stability of the movement of the adjusting plate 46, thereby adjusting... The position of the first connector B1 inside the adjusting housing 35 allows for precise docking of the first connector B1 with different connector components. Simultaneously, the bearing seat 30 on the dual-axis servo motor 22 supports the drive shaft 29, ensuring stable operation of the transmission system and improving the equipment's adaptability to different connector assemblies. The dual-axis servo motor 22 drives the switching disk 15 to rotate via the first multi-stage telescopic cylinder 3. The reset port 13 on the switching disk 15 rotates accordingly. When it is necessary to switch the model of the first connector B1, the first reset spring 41 inside the second multi-stage telescopic cylinder 32 pushes the limit disk 33, causing the pressure column 17 to dock with the adjusting unit below the different reset ports 13. The arc-shaped housing 4 and the stabilizing frame 6 ensure stable rotation of the annular ring 16 and the switching disk 15, enabling rapid switching between different connector models.Each reset port 13 is equipped with an adjustment unit of different models to accommodate different models of connectors B1, increasing the compatibility and assembly efficiency of the equipment. When the equipment is working, the PLC programmable controller 5 sends a control signal to the electric telescopic rod 34 according to a preset program or external instructions. The telescopic end of the electric telescopic rod 34 drives the first splicing joint A1 to move. The first conveying shell 10 is connected to the main body of the equipment through four connecting posts 9. The four support feet 49 firmly support the second conveying shell 11 above the first conveying shell 10, providing a stable channel for the conveying of connector components. The first conveying gear 8 and the second conveying gear 7 slide in the first conveying shell 10 and the second conveying shell 11 respectively, and multiple second splicing joints A2 and multiple second connectors are provided on them. B2, the first infrared ranging sensor 12 and the second infrared ranging sensor 48 of the Panasonic VZ series pyroelectric infrared sensor model EKMC1603111 can detect the rotation angle of the switching disk 15, preventing insufficient assembly accuracy due to errors in the rotation of the switching disk 15, and realizing the initial positioning and conveying preparation of the connector components. The electric telescopic rod 34 pushes the first splice A1 to move, and the first splice A1 contacts and squeezes the two first extrusion plates 52 inside the first conveying shell 10. The first extrusion plates 52 push the first compression cylinder 53 to slide, so that the second return spring 55 is compressed to generate elastic force. The first extrusion plates 52 are movable to facilitate the installation of different models of the first splice A1 inside the first conveying shell 10. Similarly, the second splice A1... 2. The second connector B2 contacts and presses against the corresponding first pressing plate 52 and second pressing plate 51, compressing the corresponding second return spring 55 and third return spring 63. These elastic forces cause the first pressing plate 52 and second pressing plate 51 to tightly clamp the connector component, and the first connector B1 engages with the first splice A1, further enhancing the stability of the connection and preventing the connector component from shaking or shifting during transportation. The PLC programmable controller 5 sends a control signal to the second stepper motor 50, which starts and its output drives the first rotating shaft 56 to rotate. The first rotating shaft 56 rotates stably on the inner wall of the second conveying shell 11 through the fifth bearing 57, driving the first forward gear 58 to rotate. The first forward gear 58 drives the second forward gear 59 to rotate via the second rotating shaft 60. The second rotating shaft 60 is stably supported by the sixth bearing 61 and the seventh bearing 23. The first forward gear 58 and the second forward gear 59 mesh with the first conveying gear frame 8 and the second conveying gear frame 7, respectively. Under the action of gear transmission, the first conveying gear frame 8 and the second conveying gear frame 7 move within the first conveying housing 10 and the second conveying housing 11, realizing the rapid conveying of connectors and splice joints. The first connector B1 and the first splice joint A1 on the first conveying gear frame 8 and the second conveying gear frame 7 can be inserted through external equipment for convenient continuous assembly. This precise gear transmission structure ensures the stability and accuracy of the conveying and improves the assembly efficiency of the connectors.
