Description

Technical Field

[0001] This utility model belongs to the field of connector automated assembly technology, specifically a press-fitting mechanism for a connector assembly machine. Background Technology

[0002] Ethernet connectors (such as RJ45 connectors) serve as crucial interfaces for data transmission. Their housings typically integrate LEDs to visually indicate link connectivity and data transmission status. The assembly quality of the LEDs and connector housing directly impacts the ease of equipment maintenance and the reliability of signal transmission. In mass production of connectors, the press-fit mechanism is the core equipment for automating the assembly of LEDs and housings. It uses mechanical force to precisely press the LEDs into pre-set mounting holes in the housing, replacing manual pressing to improve production efficiency. Simultaneously, it ensures the stability of electrical connections and the robustness of the mechanical structure during assembly, providing fundamental support for the mass production of communication equipment, network terminals, and other products.

[0003] Existing pressing mechanisms still have many shortcomings in practical applications: Regarding positioning and adaptation, most mechanisms use fixed-size positioning fixtures. When switching to different connector housing specifications, the entire positioning component needs to be replaced, increasing fixture inventory costs and extending production changeover time. Some adjustable positioning mechanisms rely on manual screw turning to adjust the spacing, and positioning accuracy is greatly affected by operator experience, making it difficult to meet the consistency requirements of mass production. In terms of assembly accuracy and component protection, housing positioning and LED positioning are mostly independent benchmarks. Misalignment easily occurs between the LED's luminous surface and the housing's light-transmitting window, resulting in poor indication. During pressing, the lifting-driven pressing head often has rigid contact, lacking an effective buffer structure. As a brittle component, the LED is prone to chip breakage or pin deformation due to excessive instantaneous pressing force. Furthermore, some mechanisms lack real-time monitoring of the pressing position, making it difficult to promptly identify abnormalities such as incomplete pressing or over-pressing, potentially increasing rework costs in subsequent inspection stages. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a press-fitting mechanism for a connector assembly machine, which solves the problem of inaccurate positioning and protection of connector LEDs during assembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressing mechanism for a connector assembly machine, characterized in that it includes a base, a positioning component, and a pressing component. The base is configured as a rectangular plate, with a cylindrical guide post vertically fixed at each of the front and rear ends of the top of the base. The guide posts are symmetrical about the width of the base. The positioning component is located at the middle of the top of the base and is symmetrical about the length of the base. The positioning components abut against each other. The pressing component is slidably mounted on the guide posts, and the center of the bottom of the pressing component is directly opposite the center of abutment between the two positioning components. The positioning component includes a slide table, which is slidably connected to the positioning component, and an LED positioning unit is fixed on the top surface of the slide table.

[0006] Optionally, the positioning assembly further includes a base, a drive motor, a coupling, a lead screw, and a guide rod. The base is installed on a pedestal, and the guide rod and lead screw are both installed inside the base. The guide rod is symmetrical about the lead screw. The coupling is also installed inside the base, with one end connected to the lead screw and the other end connected to the drive motor through the base. The slide is driven by the drive motor and slidably connected to the lead screw and guide rod.

[0007] Optionally, the LED positioning unit consists of a positioning block, an elastic positioning pin, and a first spring. The positioning block is fixed on the top surface of the slide table and moves left and right with the slide table. Each of the two positioning blocks has a rectangular positioning groove on its opposite side. The groove openings are opposite each other, the groove width is adapted to the thickness of the connector housing, and the length is consistent with the front and rear length of the connector housing. A circular mounting hole is provided at the bottom of each positioning groove. The elastic positioning pin slides through the mounting hole. The top of the elastic positioning pin extends out of the positioning groove and is set as a conical head. A circular limiting ring is provided in the middle of the elastic positioning pin and the limiting ring is fixed in the positioning groove. The first spring is sleeved on the elastic positioning pin in the mounting hole, with its top end abutting against the limiting ring and its bottom end abutting against the inner wall of the mounting hole.

[0008] Optionally, the pressing assembly consists of a connecting seat, a pressing seat, a pressing head, a lifting mechanism, and a second spring. The connecting seat is installed at the top of the guide column, the top of the output shaft of the lifting mechanism is connected to the pressing seat, and the pressing seat is connected to the pressing head through multiple second springs. Both the pressing seat and the pressing head are driven by the lifting mechanism and slide up and down on the guide column.

[0009] Optionally, a position sensor is also connected to the middle section of the guide column, and the drive motor, the elevator, and the position sensor are all controlled by a control unit.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: In this invention, the positioning component, through the transmission cooperation of a drive motor, coupling, and lead screw, drives the slide table to slide smoothly along the guide rod, realizing the automatic adjustment of the positioning block spacing. Compared with manual adjustment, this not only reduces the difficulty of operation but also allows for precise control of the adjustment stroke through the control unit, adapting to Ethernet connector housings of different thicknesses and lengths. The guide rod is symmetrically arranged around the lead screw, which can effectively limit the deflection of the slide table during the sliding process, ensuring that the positioning slots of the positioning blocks always remain coaxially aligned, providing a stable reference for subsequent assembly.

[0011] In this invention, the conical head of the elastic positioning pin of the LED positioning unit can be accurately inserted into the pin hole of the LED lamp, and the positioning pin is directly installed at the bottom of the positioning groove of the positioning block, so that the positioning reference of the LED lamp is consistent with the positioning reference of the housing, realizing the coaxial positioning of the LED lamp light-emitting surface and the light-transmitting window of the housing; during the pressing process, the elastic positioning pin can slide along the mounting hole as the LED lamp is pressed in, and the elastic force of the first spring can maintain the contact state between the positioning pin and the pin hole until the LED lamp is fully pressed into place, effectively reducing the alignment deviation.

[0012] In this invention, the second spring between the pressing base and the pressing head forms a graded buffer structure. When the pressing head contacts the LED and begins pressing, the second spring is gradually compressed to absorb part of the pressing impact force, avoiding damage to the LED chip caused by rigid pressing. At the same time, the extension and retraction of the elastic positioning pin can guide the LED to smoothly enter the mounting hole, reducing the scratching between the pin and the hole wall and reducing the risk of pin deformation.

[0013] In this invention, the position sensor in the middle section of the guide column can detect the descent height of the pressing seat in real time and transmit the signal to the control unit for comparison with the preset pressing stroke parameters. When the pressing seat reaches the preset position, the control unit can promptly control the lifting machine to stop driving to avoid overpressure. At the same time, the actions of the drive motor and the lifting machine are uniformly scheduled by the control unit, reducing parameter fluctuations caused by manual intervention, keeping the assembly accuracy and pressing force of products in the same batch stable, and improving the consistency of overall product quality.

Detailed Implementation

[0015] 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.

[0016] like Figure 1 As shown in the figure, this utility model provides a pressing mechanism for a connector assembly machine. It is characterized by comprising a base 1, a positioning component, and a pressing component. The base 1 is a rectangular plate. A cylindrical guide post 2 is vertically fixed at each of the front and rear ends of the top of the base 1. The guide posts 2 are symmetrical about the width of the base 1. The positioning component is located at the middle of the top of the base 1 and is symmetrical about the length of the base 1. The positioning components abut against each other. The pressing component is slidably mounted on the guide posts 2, with the center of the bottom of the pressing component directly opposite the center of the abutment of the two positioning components. The positioning component includes a slide 4, which is slidably connected to the positioning component. An LED positioning unit 3 is fixed on the top surface of the slide 4.

[0017] The positioning assembly also includes a base 5, a drive motor 6, a coupling 7, a lead screw 8, and a guide rod 9. The base 5 is installed on the base 1. The guide rod 9 and the lead screw 8 are both installed inside the base 5, and the guide rod 9 is symmetrical about the lead screw 8. The coupling 7 is also installed inside the base 5, with one end connected to the lead screw 8 and the other end connected to the drive motor 6 through the base 5. The slide table 4 is driven by the drive motor 6 and is slidably connected to the lead screw 8 and the guide rod 9.

[0018] Specifically, the positioning component drives the slide table 4 to slide smoothly along the guide rod 9 through the transmission cooperation of the drive motor 6, coupling 7 and lead screw 8, realizing the automatic adjustment of the spacing of the positioning blocks 10. Compared with the manual adjustment method, it not only reduces the operation difficulty, but also allows the adjustment stroke to be precisely controlled by the control unit, adapting to Ethernet connector housings of different thicknesses and lengths. The guide rod 9 is symmetrically arranged with the lead screw 8 as the center, which can effectively limit the deflection of the slide table 4 during the sliding process, ensuring that the positioning grooves 20 of the positioning blocks 10 always remain coaxially aligned, providing a stable reference for subsequent assembly.

[0019] The LED positioning unit 3 consists of a positioning block 10, an elastic positioning pin 11, and a first spring 12. The positioning block 10 is fixed on the top surface of the slide table 4 and moves left and right with the slide table 4. Each of the two positioning blocks 10 has a rectangular positioning groove 20 on its opposite side. The grooves 20 are opposite each other, the width of the groove is adapted to the thickness of the connector housing, and the length is consistent with the front and rear length of the connector housing. A circular mounting hole 13 is provided at the bottom of each positioning groove 20. The elastic positioning pin 11 slides through the mounting hole 13. The top of the elastic positioning pin 11 extends out of the positioning groove 20 and is set as a conical head. A circular limiting ring 21 is provided in the middle of the elastic positioning pin 11 and the limiting ring 21 is fixed in the positioning groove 20. The first spring 12 is sleeved on the elastic positioning pin 11 in the mounting hole 13, with its top end abutting against the limiting ring 21 and its bottom end abutting against the inner wall of the mounting hole 13.

[0020] Specifically, in the LED positioning unit 3, the conical head of the elastic positioning pin 11 can be precisely inserted into the pin hole of the LED lamp, and the positioning pin 11 is directly installed at the bottom of the positioning groove 20 of the positioning block 10, so that the positioning reference of the LED lamp is consistent with the positioning reference of the housing, realizing the coaxial positioning of the LED lamp light-emitting surface and the light-transmitting window of the housing; during the pressing process, the elastic positioning pin 11 can slide along the mounting hole 13 as the LED lamp is pressed in, and the elastic force of the first spring 12 can maintain the contact state between the positioning pin 11 and the pin hole until the LED lamp is completely pressed into place, effectively reducing the alignment deviation.

[0021] The pressing assembly consists of a connecting seat 14, a pressing seat 15, a pressing head 16, a lifting mechanism 17, and a second spring 18. The connecting seat 14 is installed at the top of the guide column 2. The top of the output shaft of the lifting mechanism 17 is connected to the pressing seat 15. The pressing seat 15 is connected to the pressing head 16 through multiple second springs 18. Both the pressing seat 15 and the pressing head 16 are driven by the lifting mechanism 17 and slide up and down on the guide column 2.

[0022] Specifically, the second spring 18 between the press-fit base 15 and the press-fit head 16 forms a graded buffer structure. When the press-fit head 16 contacts the LED and begins press-fitting, the second spring 18 is gradually compressed to absorb part of the press-fitting impact force, avoiding damage to the LED chip caused by rigid press-fitting. At the same time, the extension and retraction movement of the elastic positioning pin 11 can guide the LED to smoothly enter the mounting hole 13, reducing the scratching between the pin and the hole wall and reducing the risk of pin deformation.

[0023] The guide column 2 is also connected to a position sensor 19 in the middle section. The drive motor 6, the elevator 17 and the position sensor 19 are all controlled by the control unit.

[0024] Specifically, the position sensor 19 in the middle section of the guide column 2 can detect the descent height of the pressing seat 15 in real time and transmit the signal to the control unit for comparison with the preset pressing stroke parameters. When the pressing seat 15 reaches the preset position, the control unit can promptly control the lifting machine 17 to stop driving to avoid overpressure. At the same time, the actions of the drive motor 6 and the lifting machine 17 are uniformly scheduled by the control unit, reducing parameter fluctuations caused by manual intervention, keeping the assembly accuracy and pressing force of products in the same batch stable, and improving the consistency of overall product quality.

[0025] The working principle and usage process of this utility model are as follows: After starting the equipment, the control unit drives the drive motor 6, which in turn drives the lead screw 8 to rotate through the coupling 7, causing the slide 4 to slide along the guide rod 9. The distance between the two positioning blocks 10 is adjusted to match the connector housing to be installed. Then, the housing is placed into the positioning groove 20, and the LED light is placed above the mounting hole of the housing, with its pins aligned with the conical head of the elastic positioning pin 11. The control unit starts the lifting machine 17, which drives the pressing seat 15 and the pressing head 16 to slide down along the guide column 2. The pressing head 16 first contacts the LED light, and the elastic positioning pin 11 is inserted into the pin hole under the action of the first spring 12, guiding the LED light to align with the light-transmitting window of the housing. As it continues to slide down, the second spring 18 is compressed to buffer the pressing force. When the position sensor 19 detects that the pressing seat 15 has reached the preset position, the control unit stops the lifting machine 17. After the pressing is completed, the drive motor 6 drives the slide 4 to reset, and the assembled connector can be removed.
