Connector production and assembly equipment and method

Abstract

The present invention discloses a connector production and assembly device and method, and specifically relates to the technical field of connector assembly. The clamping strip of the present invention slides in the bottom groove and fits the buckle on the pin group to calibrate the pin group. Then the bidirectional screw in the push plate 1 rotates, and the sliding seat drives the push piece to contact the inclined table. The clamping block follows the movement of the slide seat and stretches outward to open at the same time. The middle part of the buckle on the pin group is clamped by the clamping block, and the push plate 1 pushes the clamped pin buckle to approach the discharge end of the material cavity 2, while the clamping blocks on both sides slide in a limited manner along the direction of the limit track. The end face of the plastic shell is in close contact with the surface of the card frame. Since the height of the material cavity 2 is higher than that of the material cavity 1, the pin group passes through the card frame and is smoothly plugged into the plastic shell. The position alignment makes the plugging process smoother, and no additional adjustment and attempt are required, thereby improving the assembly efficiency.

[0017] A method for producing and assembling a connector, the method comprising the following steps:

[0018] Step 1: The pin group is transported from the second cavity, and the pin group is first calibrated by the clamping strip, and then the two clamping blocks are used to clamp the buckle of the pin group, and then the clamped pin group is pushed to the discharge end of the second cavity by the push plate 1. At this time, the clamping block slides directionally along the limit track;

[0019] Step 2: The plastic shell is pushed by the push plate 2 to abut against the end surface of the card frame. At this time, the plastic shell is located on the upper surface of the lifting seat. After the pin group is positioned and plugged with the plastic shell, the position of the plastic shell is limited by the sliding of the pressure block on the linear guide rail, and then the connecting frame is pushed away from the discharge end of the second material chamber by the reciprocating cylinder. At this time, the plastic shell and the pin in the lifting seat are pushed down to the position connected with the positioning transfer chamber by the synchronous lifting cylinder;

[0020] Step 3: The pin plastic shell is conveyed into the positioning transfer cavity by the conveyor belt, and the plastic shell is clamped by the clamping claws. Then the cutting frame is slidably sleeved on the outside of the positioning transfer cavity. The cutter is adjacent to the buckle surface of the pin group. The highest point of the eccentric cam is in contact with the convex ring through rotation, which drives the shaft rod on the convex ring and its cutter to reciprocate and separate the buckle from the pin.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. In the present invention, the pin group adopts multiple pins, and their relative positions are kept consistent, which is conducive to ensuring the overall performance of the connector. When the pin group is close to the inner wall of the end of the second cavity, the clamping strip slides in the bottom groove and fits the buckle on the pin group to calibrate the pin group. Then the bidirectional screw in the push plate 1 rotates, causing the slide seat to slide and the push piece to move together. At this time, the push piece is in contact with the inclined platform, and the push piece pushes the elastic extrusion piece to move in the slide seat. At this time, the clamping block moves with the slide seat and extends outward to open until the push piece reaches the plane of the inclined platform. The clamping block only slides but does not retract, and the middle part of the buckle on the pin group is clamped by the clamping block. Then, the push plate 1 pushes the clamped pin buckle toward the discharge of the second cavity. The ends are close to each other, and the clamping blocks on both sides slide in a limited position along the direction of the limiting track to ensure that the pin group and the plastic shell are accurately installed, avoid poor contact, ensure the reliability of the connection, reduce the circuit disconnection or signal transmission instability caused by poor contact, and prevent the pins from bending or deforming during insertion; the end face of the plastic shell is close to the surface of the card frame, and then the pin group passes through the card frame. Since the height of the material cavity two is higher than the height of the material cavity one, that is, when the pin group passes through the card frame and contacts with the plastic shell, it is just installed in the insertion position in the plastic shell. At this time, the pins and buckles are installed on the plastic shell, which realizes the alignment of the pin group and the plastic shell and automatic plug-in installation. The position alignment makes the plug-in process smoother, without additional adjustment and trial, and improves the assembly efficiency.

[0023] 2. Use the linear guide to drive the pressing block to limit the end of the plastic shell, and then move the position of the connecting frame, that is, through the push of the reciprocating cylinder, the connecting frame and its clamping frame move toward the discharge end face of the second material chamber, which is convenient for the downward movement of the lifting seat. When the lifting seat moves downward, the synchronous lifting cylinder pushes the lifting seat downward, and the connecting rod synchronously drives the slider to slide in the first material chamber. At this time, the plastic shell and the pin group move down with the lifting seat to the position connected with the positioning transfer chamber. Through the transmission of the conveyor belt, the pin group and its plastic shell enter the positioning transfer chamber for the next step of operation;

[0024] 3. The rubber shell is positioned and clamped by the clamping claws in the positioning and transfer chamber, and then the cutting frame approaches the fixed position. At this time, the cutters in the two sets of cutting units are aligned with the insertion point of the pin on the buckle. Through the rotation of the driving shaft in the cutting unit, the highest point of the eccentric cam contacts the convex ring, so that the shaft on the convex ring and its cutter move, and the cutter presses and cuts the pin insertion point on the upper part of the buckle. At this time, the reset block squeezes spring three to achieve reciprocating motion. Through the meshing action of the gears, the other set of cutting units moves synchronously and presses and cuts the pin insertion point at the bottom of the buckle, thereby realizing the separation of the buckle and the pin. The broken buckles after pressing and cutting are collected by the material plate. BRIEF DESCRIPTION OF THE DRAWINGS

In the initial state, the pressing strip 8 is located inside the bottom groove 14, and the push plate 1 7 is received on the inner wall surface of the material cavity 2 5. When the pin group is close to the inner wall of the end of the material cavity 2 5, the pressing strip 8 slides in the bottom groove 14 and fits the buckle on the pin group. Then the bidirectional screw 26 in the push plate 1 7 rotates, causing the slide seat 28 to slide, and the push piece 25 is driven to move together during the sliding. At this time, the push piece 25 and the inclined The platform 24 is in contact with the push piece 25, and the push piece 25 pushes the elastic extrusion piece to move in the slide seat 28. At this time, the clamping block 31 moves with the slide seat 28 and stretches outward to open until the push piece 25 reaches the plane of the inclined platform 24. The clamping block 31 only slides but does not extend or retract. The two clamping blocks 31 move toward the direction of the push plate 1 7, and then clamp the middle part of the buckle on the pin assembly. Then, the push plate 1 7 pushes the clamped pin buckle to move toward the discharge end of the cavity 2 5. During the process, the clamping blocks 31 on both sides slide in the direction of the limiting track 6 to ensure that the pin group and the plastic shell are accurately installed, avoid poor contact, ensure the reliability of the connection, reduce the circuit disconnection or signal transmission instability caused by poor contact, prevent the pin from bending or deformation during plugging, avoid damage to the plastic shell jack, and extend the service life of the component; at the same time, the plastic shell enters from the direction of the material cavity 1 2, and after being pushed by the push plate 2 13, the end face of the plastic shell is close to the surface of the card frame 10, and then the pin group passes through the card frame 10. Since the height of the material cavity 2 5 is higher than the height of the material cavity 1 2, that is, when the pin group passes through the card frame 10 and contacts with the plastic shell, it is just installed in the plug-in position in the plastic shell. At this time, the pin and the buckle are installed on the plastic shell, realizing the alignment of the pin group and the plastic shell and automatic plug-in installation. The position alignment makes the plug-in process smoother, without the need for additional adjustments and attempts, improving assembly efficiency, and reducing errors and time costs of manual operations.

[0037] See also Figure 2 and Figure 3 As shown, an inclined block 16 is fixedly arranged on the inner wall surface of the bottom groove 14, and a correction cylinder 15 is installed at the end of the inner wall surface of the bottom groove 14, and a guide block 18 is fixedly connected to the pushing end of the correction cylinder 15.

A spring 19 is installed at the end of the inner wall surface of the guide groove 17, and one end of the spring 19 is fixed to the guide block 18. When the pin group is close to the end of the material cavity 2 5, When the pressing strip 8 contacts the wall, the correction cylinder 15 pushes the guide block 18, so that the pressing strip 8 is in contact with the inclined block 16. Under the push of the inclined surface, the guide block 18 slides in the guide groove 17, so that the pressing strip 8 slides away from the inside of the bottom groove 14, and the buckle on the pin group of the pressing strip 8 fits tightly with the inner wall surface of the cavity 2 5, which is convenient for clamping the pins and squeezes the spring 19 at the same time. When the external force of the spring 19 disappears, the pressing strip 8 is reset and hidden in the bottom groove 14, which does not affect the transportation of the pin group.

[0038] See also Figure 4 As shown, the outwardly protruding surface of the push plate 1 7 is provided with a sliding groove 27 for limiting the sliding of the slide 28. The elastic extrusion member includes a push rod 29 with a T-shaped structure arranged inside the slide 28. The outer sleeve of the push rod 29 is provided with a spring 2 30. The spring 2 30 is fixed to the inner wall surface of the slide 28. The slide 28 is driven by the movement of the bidirectional screw 26. The slide 28 always moves in a directional manner in the sliding groove 27. When the push member 25 contacts the ramp 24, the push member 25 pushes the push rod 29 to move in the slide 28, and at the same time squeezes the spring 2 30, so that the clamping block 31 extends outward.

[0039] See also Figure 6 As shown, a reciprocating cylinder 20 fixedly connected to the bottom surface of the connecting frame 9 is installed on the lower surface of the discharge end of the material chamber 2 5, and a mounting seat 23 is installed on the outer wall surface of the discharge end of the material chamber 2 5 and the material chamber 1 2, and a fixing block 21 is installed on the outer wall surface of the connecting frame 9, and the end of the mounting seat 23 is fixedly connected to a limiting rod 22 which slides with the fixing block 21. When the pin group and the plastic shell are docked and installed, the connecting frame 9 and its clamping frame 10 move toward the discharge end surface of the material chamber 2 5 through the push of the reciprocating cylinder 20, and the connecting frame 9 is supported by the sliding of the fixing block 21 on the limiting rod 22. At this time, the pin group is released from the restriction, which is convenient for the subsequent operation of lowering the pin group and the plastic shell.

[0040] See also Figure 5 and Figure 7 As shown, the inner wall surface of the discharge end of the material cavity 2 is embedded with a linear guide 11, and the outer side of the linear guide 11 is slidably provided with a pressure block 12 for pressing the end of the plastic shell, and the pressure block 12 is set in an L shape. The inner side of the linear guide 11 is connected with a slider 32 that slides in the material cavity 2, and the bottom surface of the discharge end of the material cavity 2 is embedded with a lifting seat 34 driven by a synchronous lifting cylinder, and the top end of the lifting seat 34 is installed with a connecting rod 33 fixedly connected to the slider 32, and the top surface of the lifting seat 34 is embedded with a conveyor belt 35. Initially, the pressure block 12 is located at the upper part of the plastic shell. After the plastic shell is fitted and pressed against the card frame 10, the linear guide 11 is first used to drive the pressing block 12 to limit the end of the plastic shell, and then the position of the connecting frame 9 is moved to facilitate the downward movement of the lifting seat 34. When the lifting seat 34 moves downward, the synchronous lifting cylinder pushes the lifting seat 34 downward, and the connecting rod 33 synchronously drives the slider 32 to slide in the material chamber 2. At this time, the plastic shell and the pin group follow the lifting seat 34 and move downward to a position connected with the positioning and transfer chamber 3. Through the transmission of the conveyor belt 35, the pin group and its plastic shell enter the positioning and transfer chamber 3 for the next step of operation.

[0041] See also Figure 1 and Figure 8As shown, one side of the outer wall of the material cavity 1 2 is connected to a positioning transfer cavity 3, a clamping claw for clamping the plug pin plastic shell is arranged inside the positioning transfer cavity 3, and a cutting frame 4 is slidably arranged outside the positioning transfer cavity 3, a pressing and cutting component for cutting the buckle on the plug pin up and down is arranged inside the cutting frame 4, and a material plate 42 is arranged at the bottom of the inner cavity of the cutting frame 4;

[0042] The pressure cutting assembly includes two sets of cutting units, the two sets of cutting units are meshed by gears 41, and the cutting units include an eccentric cam 37 fixedly sleeved on the outside of the driving shaft, and a convex ring 38 is provided on the outside of the eccentric cam 37. The end of the shaft on the convex ring 38 is fixedly connected with a reset block 39 sliding on the inner wall of the cutting frame 4, and the outside of the shaft on the convex ring 38 is fixedly connected with a cutter 36, and the end of the reset block 39 is fixedly connected with a spring 40 embedded on the inner wall of the cutting frame 4. After entering the positioning and transfer cavity 3, the rubber shell is first positioned and clamped by the clamping claw, and then the cutting frame 4 approaches the fixed position. At this time, the cutters 36 in the two sets of cutting units are aligned with the insertion position of the pin on the buckle, such as Figure 8 As shown, through the rotation of the driving shaft in the cutting unit, the highest point of the eccentric cam 37 contacts the convex ring 38, so that the shaft on the convex ring 38 and its cutter 36 move, and the cutter 36 presses and cuts the pin insertion part on the upper part of the buckle. At this time, the reset block 39 squeezes the spring three 40, thereby realizing reciprocating motion. Through the meshing action of the gear 41, the other set of cutting units moves synchronously, and synchronously presses and cuts the pin insertion part at the bottom of the buckle, thereby realizing the separation of the buckle and the pin. The broken buckles after pressing and cutting are collected by the material plate 42.

[0043] A method for producing and assembling a connector, the method comprising the following steps:

[0044] Step 1: The pin group is transported from the second cavity 5, and the pin group is first calibrated by the pressing strip 8, and then the pin group is clamped by the two clamping blocks 31, and then the clamped pin group is pushed to the discharge end of the second cavity 5 by the push plate 1 7. At this time, the clamping block 31 slides directionally along the limit track 6;

[0045] Step 2: The plastic shell is pushed by the push plate 13 to abut against the end surface of the card frame 10. At this time, the plastic shell is located on the upper surface of the lifting seat 34. After the pin group is positioned and plugged with the plastic shell, the position of the plastic shell is limited by the sliding of the pressure block 12 on the linear guide 11. Then, the reciprocating cylinder 20 pushes the connecting frame 9 away from the discharge end of the material chamber 5. At this time, the synchronous lifting cylinder is used to push the plastic shell and the pin in the lifting seat 34 down to a position connected with the positioning transfer chamber 3.

[0046] Step 3: The pin plastic shell is conveyed into the positioning transfer chamber 3 by the conveyor belt 35, and the plastic shell is clamped by the clamping claws. Then the cutting frame 4 is slidably sleeved on the outer side of the positioning transfer chamber 3, and the cutter 36 is adjacent to the buckle surface of the pin assembly. The highest point of the eccentric cam 37 is in contact with the convex ring 38 through rotation, which drives the shaft rod on the convex ring 38 and its cutter 36 to reciprocate, and the buckle is separated from the pin.

[0047] When the present invention is in use, when the pin group is close to the inner wall of the end of the cavity 25, the clamping strip 8 slides in the bottom groove 14 and fits the buckle on the pin group to calibrate the pin group. Then the bidirectional screw 26 in the push plate 17 rotates to make the slide 28 slide, and drives the push piece 25 to move together during sliding. At this time, the push piece 25 is in contact with the inclined platform 24, and the push piece 25 pushes the elastic extrusion piece to move in the slide 28. At this time, the clamping block 31 moves with the slide 28 and stretches outward to open until the push piece 25 reaches the plane of the inclined platform 24. The clamping block 31 only slides but does not retract. The middle part of the buckle on the pin group is clamped by the clamping block 31, and then the push plate 17 pushes the clamped pin buckle toward the discharge end of the cavity 25. The clamping blocks 31 on both sides slide along the direction of the limiting rails 6 to ensure that the pin group and the plastic shell are accurately installed, avoid poor contact, ensure the reliability of the connection, reduce the circuit disconnection or signal transmission instability caused by poor contact, and prevent the pins from bending or deforming during insertion; the end face of the plastic shell is in close contact with the surface of the card frame 10, and then the pin group passes through the card frame 10. Since the height of the material cavity 2 5 is higher than the height of the material cavity 1 2, that is, when the pin group passes through the card frame 10 and contacts with the plastic shell, it is just installed in the insertion position in the plastic shell. At this time, the pins and buckles are installed on the plastic shell, realizing the alignment of the pin group and the plastic shell and automatic plug-in installation. The position alignment makes the plug-in process smoother, without additional adjustment and trial, and improves the assembly efficiency.

[0048] The linear guide 11 is used to drive the pressing block 12 to limit the end of the plastic shell, and then the position of the connecting frame 9 is moved, that is, through the push of the reciprocating cylinder 20, the connecting frame 9 and its clamping frame 10 move toward the discharge end surface of the material chamber 2 5, which is convenient for the downward movement of the lifting seat 34. When the lifting seat 34 moves downward, the synchronous lifting cylinder pushes the lifting seat 34 downward, and the connecting rod 33 synchronously drives the slider 32 to slide in the material chamber 2. At this time, the plastic shell and the pin group follow the lifting seat 34 and move downward to the position connected with the positioning transfer chamber 3. Through the transmission of the conveyor belt 35, the pin group and its plastic shell enter the positioning transfer chamber 3 to perform the next step of operation;

[0049] The rubber shell is positioned and clamped by the clamping claws in the positioning and transfer chamber 3, and then the cutting frame 4 approaches the fixed position. At this time, the cutters 36 in the two groups of cutting units are aligned with the insertion point of the pin on the buckle. Through the rotation of the driving shaft in the cutting unit, the highest point of the eccentric cam 37 contacts the convex ring 38, so that the shaft on the convex ring 38 and its cutter 36 move, and the cutter 36 presses and cuts the pin insertion point on the upper part of the buckle. At this time, the reset block 39 squeezes the spring three 40 to achieve reciprocating motion. Through the meshing action of the gear 41, the other group of cutting units moves synchronously and presses and cuts the pin insertion point at the bottom of the buckle synchronously, thereby realizing the separation of the buckle and the pin, and the broken buckles after pressing and cutting are collected by the material plate 42.
