[0002] The present invention relates to the technical field of radio frequency connectors, and in particular to a multi-action linked radio frequency connector insulator bisection device. Background Art

[0003] In the field of RF connectors, to increase connector frequency and ensure compactness, many connectors utilize a single insulator support design. During installation, the insulator must be cut in half and then inserted along the pin step. The current practice is to manually cut the insulator in half with a blade and then insert the cut insulator into the pin step using tweezers or by hand. Due to the small size of the insulators, manual assembly presents several challenges: 1. Manual cutting is inefficient and produces poor results, making defective products prone to defects and difficult to detect. 2. Commonly used insulators have an outer diameter between 2.6mm and 3.5mm and a thickness between 1.2mm and 1.5mm. Their top and bottom surfaces share the same structure. During manual assembly, it's easy for the cut insulator to be installed upside down, and this can go undetected, leading to assembly failure and reduced performance and reliability of the finished product. 3. Manually inserting the cut insulator into the pin slot can easily lead to material loss. Summary of the Invention

[0039] To illustrate the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and accompanying drawings.

[0040] Please refer to Figure 1 as well as Figure 15 , provides a radio frequency connector insulator cutting device, including a centering mechanism, a needle feeding mechanism, a pre-installation mechanism and a cutting mechanism;

[0041] The centering mechanism is provided with a cutting station and a clamping station; the centering mechanism includes two movable blocks that move toward or away from each other in the horizontal direction, the movable blocks are provided with a movable clamping block, and the opposing surfaces of the two clamping blocks are respectively provided with placement grooves that are spliced ​​in half. When the two placement grooves are located at the cutting station, the two placement grooves are spliced ​​together to form a groove body that is compatible with the insulator to be cut; when the placement grooves are located at the clamping station, there is a gap between the two placement grooves;

[0042] The pre-installation mechanism is provided with a material taking station, which is pre-installed with insulators to be cut; the pre-installation mechanism includes a conveying seat interconnected with the needle feeding mechanism and moving together in a horizontal direction, wherein the horizontal direction is perpendicular to the movement direction of the movable block;

[0043] A horizontally arranged conveying plate is provided on the conveying seat, the conveying plate is located above the two clamping blocks and between the two clamping blocks, and the conveying plate is provided with an insulator groove adapted to the insulator to be cut;

[0044] The needle feeding mechanism includes a needle feeding seat arranged between the two movable blocks and reciprocating between a first position and a second position, the needle feeding seat being provided with a pin for engaging with the insulator to be cut; when the needle feeding seat is in the first position, the two placement slots are both located on the clamping station, the pin is located between the gaps between the two placement slots, and the insulator slot on the conveying plate is located on the material taking station; when the needle feeding seat is in the second position, the two placement slots are both located on the cutting station, the pin is located outside the two placement slots, and the insulator slot on the conveying plate is located on the cutting station and is coaxial with the slot body formed by the two placement slots;

[0045] The cutting mechanism includes a blade that can move in a vertical direction. The blade is located directly above the cutting station, and the cutting surface of the blade and the contact surface when the two placement grooves are spliced ​​are located on the same vertical plane.

[0046] As can be seen from the above description, the beneficial effects of the present invention are as follows: the present invention provides an RF connector insulator bisection device, which ensures that the insulator is aligned when bisection is performed by providing a centering mechanism. During the bisection process, the clamping block can also give way to the blade of the cutter mechanism, avoiding the situation of cutting the knife and squeezing the insulator during the bisection process, thereby ensuring the insulator bisection effect; after the bisection of the insulator to be cut is completed, there is no need to remove the material. When the needle feeding mechanism drives the two placement slots to be located at the clamping station, the gap between the pin and the placement slot is directly assembled with the insulator, thereby improving efficiency and ensuring that the two insulators after bisection will not be installed incorrectly. By providing a pre-installation mechanism, automatic material removal and unloading of the insulator to be cut are achieved, thereby improving efficiency.

[0047] Furthermore, the preloading mechanism includes a preloading tube vertically arranged on the material-taking station, the preloading tube is located directly above the conveying plate, a first spring is provided in the preloading tube, a pin is provided on the top of the first spring, and the pin is fixedly connected to the upper end of the preloading tube; the gap between the bottom of the first spring and the upper end surface of the conveying plate is smaller than the thickness of the insulator, and the gap between the bottom of the first spring and the bottom of the insulator slot is larger than the thickness of the insulator; the insulators are preloaded in batches between the first spring and the conveying plate.

[0048] From the above description, it can be seen that by pre-installing the insulators to be cut in batches in a vertically arranged pre-installed tube, and fixing the first spring at the upper part of the pre-installed tube, the first spring presses against the insulators to be cut pre-installed in the pre-installed tube so that the spring is compressed. When the conveying plate moves to the material taking station and makes the insulator slot coaxial with the pre-installed tube, the insulators to be cut are pushed out of the pre-installed tube by the force of the first spring, so that the insulators to be cut can quickly fall into the insulator slot, thereby realizing rapid material taking.

[0049] Furthermore, the pre-installation mechanism further includes a limit block, the limit block including two baffles that are opposite and spaced apart, and the two baffles are respectively perpendicular to the conveying seat; the baffle is provided with a limit adjustment screw that passes vertically through the baffle;

[0050] A protruding block is provided on one side of the conveying seat, and the protrusion is located between the two baffles; when the insulator slot is located at the material taking station, it is coaxial with the pre-installed tube, and the protrusion contacts the limit adjustment screw on one of the baffles; when the insulator slot is located at the cutting station, the protrusion contacts the limit adjustment screw on the other baffle.

[0051] From the above description, it can be seen that the conveying seat cooperates with the limit block through the protrusion, and the limit block limits the movement stroke of the conveying seat through the limit adjustment screw on the baffle. At the same time, the limit adjustment screw can adjust the limit position, thereby adjusting the material picking position and unloading position of the conveying plate according to needs.

[0052] Furthermore, the centering mechanism includes a horizontally arranged first linear guide rail, the two movable blocks are slidably connected to the first linear guide rail, a side plate is provided at each end of the guide rail, and a third spring is provided between the end of the centering mechanism away from the center of the guide rail and the side plate, which respectively presses against the side plate and the centering mechanism.

[0053] As can be seen from the above description, the centering mechanism is slidably connected to the first linear guide rail via a movable block, and the clamping block can independently move relative to the movable block. Therefore, the needle feed seat drives the two movable blocks to move away from each other, causing the two clamping blocks to open and make room for the pins to be placed between the two placement slots. The two clamping blocks are then independently driven toward each other so that the insulators on the two clamping blocks simultaneously contact the pins on the needle feed seat. Through clamping, the insulators and the pins are connected, achieving automatic clamping between the insulators and the pins. The entire clamping process maintains the centering effect, improving operational efficiency and product yield.

[0054] Furthermore, the cutter mechanism further comprises a vertically arranged slide bar, a second spring and a support seat;

[0055] The slide bar is sleeved in the second spring and the upper portion of the slide bar extends out of the second spring. The support seat is provided on the upper portion of the slide bar and movably connected to the slide bar, and the support seat abuts against the top of the second spring.

[0056] The support seat is located above the clamping block, and the blade is arranged on the lower end surface of the support seat.

[0057] From the above description, it can be seen that when the support seat drives the blade downward to cut, the second elastic member is compressed, helping the blade to slowly descend for cutting operation, improving the stability of the insulator cutting process, and at the same time helping the blade to reset and keep the blade above the splint later.

[0058] Furthermore, it also includes a handle mechanism, the handle mechanism includes a support vertically arranged on one side of the slide rod, the support is provided with a handle with one end hinged to the support, and the middle position of the handle is located directly above the support seat;

[0059] A second straight groove is provided in the middle of the handle, and a support column is provided on the support seat opposite to the support seat. A movable pin is provided on the support column passing through the second straight groove, and the axial direction of the movable pin is parallel to the hinge axial direction between the support seat and the handle.

[0060] From the above description, it can be seen that the support column and the movable pin provide a support point for the handle above the support seat, forming a lever force, thereby improving the stability and labor-saving of the cutting operation.

[0061] Furthermore, it also includes a linkage mechanism, which includes a wedge block, a mounting plate, a wedge pin sleeve, and a wedge pin reset block;

[0062] The wedge block is arranged on the other side of the conveying seat, and a wedge-shaped reset block is provided on the wedge block, the wedge pin reset block is a right-angled triangle structure, and the right-angled triangle vertex corresponding to the wedge pin reset block is arranged downward; a vertical reset groove is provided on the wedge pin reset block, the bottom of the reset groove is inclined, and the groove depth of the reset groove gradually decreases from top to bottom;

[0063] The mounting plate is connected to the support seat, and the mounting plate is arranged opposite to the wedge-shaped reset block. The wedge pin sleeve is vertically arranged on the side wall of the mounting plate close to the wedge-shaped reset block. A fourth spring and a wedge pin are sequentially provided in the wedge pin sleeve from the inside to the outside, and the wedge pin and the wedge pin sleeve are movably connected. The distance between the end of the wedge pin and the mounting plate is smaller than the maximum distance between the bottom of the reset groove and the mounting plate and larger than the minimum distance between the bottom of the reset groove and the mounting plate.

[0064] As can be seen from the above description, by setting up a linkage mechanism, the linkage between the pre-installation mechanism, the cutter mechanism, the needle feeding mechanism and the centering mechanism is achieved. When the support seat drives the blade to press down, the wedge pin is embedded in the reset groove and abuts against the end face of the reset groove. When the blade is pressed down to the cutting station to complete the cutting of the insulator to be cut, the wedge pin slides out of the reset groove in a vertical downward direction. At the same time, the wedge pin automatically pops out under the action of the fourth spring and is tangent to the inclined surface on the hypotenuse of the right triangle corresponding to the wedge pin reset block. When the handle drives the support seat to move upward, the wedge pin reset block moves along the inclined surface of the wedge pin reset block with the wedge pin as the fulcrum, thereby driving the conveying seat to move in the horizontal direction until the insulator slot is located at the material taking station. At the same time, when the support seat drives the blade to move upward, the blade is in the process of resetting. Before the blade leaves the cutting station, the conveying plate is always above the clamping block to prevent the cut insulator from sticking to the cutter and falling off from the groove. Furthermore, the conveyor seat synchronously drives the needle feed seat to move horizontally to a second position, achieving a linked reset. During the reset process, when the blade has not completely disengaged from the insulator, the movable block driven by the conveyor seat moves in a reverse direction, causing the clamping block to open. This ensures that the cut insulator is always in the placement slot of the clamping block and completes the action of the needle feed mechanism to move the needle out of the way. The linkage mechanism drives each component to complete multiple tasks simultaneously through a single action, improving work efficiency. During the process of multiple linked actions, it also solves problems such as insulator detachment and needle feed mechanism moving the needle out of the way.

[0065] Furthermore, a limiting groove is provided on the upper portion of the movable block near one end of the needle feeding seat, and the two ends of the needle feeding seat are movably arranged on the limiting grooves of the two movable blocks respectively;

[0066] Two limit pins are provided at the lower part of the needle feeding seat, and the outer peripheral side walls of the two limit pins are respectively in contact with the end surfaces of the two movable blocks close to the needle feeding seat;

[0067] The movable block is close to one end surface of the needle feeding seat, and has a limiting surface and a vertically set connecting plane that are successively inclined along the movement direction of the needle feeding. The distance between the two limiting surfaces gradually decreases along the direction close to the connecting plane.

[0068] From the above description, it can be seen that the needle feeding seat slides on the limiting groove of the movable block, and the outer peripheral side walls of the two limiting pins on the needle feeding seat are respectively in contact with the end faces of the two movable blocks close to the center of the guide rail to maintain a tangent state. Since the limiting surfaces of the two movable blocks gradually shrink in the direction close to the connecting plane, the limiting pin generates a thrust on the limiting surface during the process of driving the needle feeding seat to move. Therefore, when the needle feeding seat moves toward the limiting groove, the movable block moves in opposite directions at the same time under the thrust of the limiting pin, so that the two clamps open to make way for the pin to be placed between the two placement grooves, which is convenient for the subsequent clamping of the insulator.

[0069] Furthermore, a sliding groove is provided on one end face of the movable block, the clamping block is slidably arranged in the sliding groove, and the sliding direction of the clamping block is the same as the movable direction of the movable block, a bow spring is provided between the clamping block and the sliding groove, and the bow spring is located in the sliding direction of the clamping block, and the two ends of the bow spring are respectively in contact with the clamping block and the sliding groove.

[0070] From the above description, it can be seen that the movable block is slidably connected to the clamping block through the sliding groove, and the bow spring can further reset the clamping block. The structure is simple and the operation is convenient.

[0071] Furthermore, it also includes a clamping mechanism, which includes a support and two connecting rods arranged on one side of the two clamping blocks;

[0072] One end of the two connecting rods is respectively connected to the two clamping blocks, and the other ends of the two connecting rods are hinged by a pin; the support is provided with a first straight groove adapted to the pin, and the pin is movably arranged in the first straight groove, and the projection surface of the first straight groove in one direction overlaps with the symmetry axis of the two connecting rods.

[0073] From the above description, it can be seen that by driving the pin shaft to move along the length direction of the first straight slot, the two hinged connecting rods can be driven to move simultaneously, and the connecting rods can further drive the two clamping blocks to move synchronously toward or away from each other, thereby realizing the clamping action.

[0074] Please refer to Figures 1 to 15Embodiment 1 of the present invention is to provide a radio frequency connector insulator cutting device, comprising a base 1, a centering mechanism 2, a needle feeding mechanism 3, a pre-installation mechanism 4, a cutting mechanism 5, a linkage mechanism 6 and a clamping mechanism 7, respectively arranged on the base.

[0075] The centering mechanism includes a first linear guide rail 21 horizontally arranged on the base, two movable blocks 22 respectively slidably arranged on the first linear guide rail, and a clamping block 23 movably arranged on the movable block. Specifically, side panels 11 are provided at both ends of the base, and the two ends of the first linear guide rail are respectively connected to the two side panels. A third spring 12 is provided between the movable block and the side panels, and the two ends of the third spring are respectively in contact with the side panels and the movable block. A slide groove is provided on the upper end surface of the movable block, and the clamping block is slidably arranged in the slide groove, and the sliding direction of the clamping block is in the same direction as the extension direction of the first linear guide rail. A bow spring 221 is provided in the slide groove. Specifically, the slide groove is composed of a groove 222 set on the upper end surface of the movable block and two pressure plates 223 respectively set on the groove. The two side walls corresponding to the groove are respectively formed to form baffles 2221. The two baffles are respectively located at the two ends of the sliding direction of the clamping block. The pressure plate is L-shaped. The two pressure plates are relatively arranged on both sides of the movable block and are perpendicular to the bottom of the groove so that the two pressure plates and the groove jointly form a convex groove body on the cross section of the sliding direction of the clamping block.

[0076] The clamping block includes a sliding portion embedded in the slide groove. The cross-section of the sliding portion is a convex shape that matches the slide groove. The bottom surface of the sliding portion is provided with a U-shaped groove that matches the bow spring. The U-shaped opening corresponding to the U-shaped groove is arranged toward the center end of the guide rail. The bow spring is embedded in the space formed by the U-shaped groove and the slide groove, and the two ends of the spring are respectively in contact with the U-shaped inner wall corresponding to the U-shaped groove and the baffle near the center end of the guide rail. In addition, the upper portion of the convex shape corresponding to the sliding portion of the clamping block is provided with a mounting portion extending in the sliding direction of the clamping block. The upper end surface of the mounting portion is provided with a clamping plate 24. The clamping plates on the two clamping blocks are respectively arranged opposite each other, and the opposing surfaces of the two clamping plates are respectively provided with a placement groove 241 that is spliced ​​in half. When the two placement grooves are spliced ​​together, they form a slot body that matches the insulator 8. The placement slot consists of two stepped holes, larger at the top and smaller at the bottom. The diameter and height of the larger hole of the placement slot are adapted to the insulator, while the diameter of the smaller hole of the placement slot is smaller than the diameter of the insulator and larger than the diameter of the pin. The smaller hole of the placement slot is used to clear the way for the subsequent pin engagement. The two clamping blocks can be driven toward or away from each other to connect or separate the two placement slots. When the two placement slots are connected, the insulator is placed in the slot body formed by the two placement slots, and the center of the insulator is coaxial with the center of the slot body. During the bisection operation, the insulator can be cut in half, aligned with the center.

[0077] The centering mechanism is provided with a cutting station and a clamping station. When the two placement slots are in contact and in a spliced ​​state, the two placement slots are both located on the cutting station; when the two placement slots are separated and the gap between the two placement slots is between 1mm and 3mm, the two placement slots are both located on the clamping station.

[0078] The pre-installation mechanism includes a horizontally arranged second linear guide 41, a conveyor seat 42, a conveyor plate 43, a pre-installation tube 44, and a limit block 45. The second linear guide is arranged on one side of the centering mechanism, perpendicular to the first linear guide and located on the central axis of the first linear guide. The conveyor seat is slidably mounted on the second linear guide, and the conveyor plate is mounted on the upper end surface of the conveyor seat, near one end of the centering mechanism, and is located above the clamping plate. The upper end surface of the conveyor plate near the centering mechanism is provided with an insulator slot 431 for accommodating insulators.

[0079] The base is also provided with a vertically mounted fixing plate, positioned near the end of the second linear guide rail that is distal from the first linear guide rail. One end of the stopper is secured to the fixing plate by screws. The stopper comprises two opposing, spaced-apart first and second baffles 451 and 452, each perpendicular to the conveyor base. A protruding bump 421 is provided on the sidewall of the conveyor base near the fixing plate. The bump is coplanar with the first and second baffles and positioned between them, thereby limiting the movement of the conveyor base. The first baffle is positioned proximate to the centering mechanism, while the second baffle is positioned distally. When the bump contacts the first baffle, the insulator slot of the conveyor plate is positioned coaxially with the slot formed by joining the two placement slots at the cutting station. When the bump contacts the second baffle, the insulator slot of the conveyor plate is positioned coaxially with the pre-assembled tube at the retrieving station.

[0080] The pre-installed tube is vertically mounted on the retrieving station, located above the clamping plate and adjacent to one side of the second linear guide rail, directly above the conveyor plate. The inner diameter of the pre-installed tube is larger than the outer diameter of the insulator. A first spring 441 is also located within the pre-installed tube, with a pin 442 located at the top. The pin is threadedly connected to the upper end of the pre-installed tube. The gap between the bottom of the pre-installed tube and the upper end surface of the conveyor plate is less than the thickness of the insulator, the gap between the bottom of the pre-installed tube and the bottom of the insulator slot is greater than the thickness of the insulator, and the gap between the bottom of the spring and the upper end surface of the conveyor plate is less than the thickness of the insulator. Multiple insulators are pre-installed within the pre-installed tube, located between the spring and the upper end surface of the conveyor plate, and the spring is compressed so that it abuts against the insulators. When the conveying plate moves to the point where the insulator slot is located on the cutting station, the insulator in the pre-installed tube is pushed out of the pre-installed tube by the action of the spring, so that the insulator can quickly fall into the insulator slot.

[0081] In this embodiment, the baffle is provided with a limit adjustment screw 46 that passes perpendicularly through the baffle. A magnet is mounted on the end of the limit adjustment screw, adjacent to the baffle. The material of the protrusion can be a magnet with opposite magnetic properties to the magnet, or other metal material that can be attracted by a magnet. The conveyor seat is magnetically connected to the magnet via the protrusion, thereby providing a securing force for the conveyor plate during material collection and discharge. Furthermore, the limit adjustment screw can adjust the limit position of the limit block, thereby adjusting the material collection and discharge positions of the conveyor plate.

[0082] The needle feeding mechanism includes a needle feeding seat 31 that is arranged between the two movable blocks and reciprocates between a first position and a second position, and a movable rod 32 that drives the movement of the needle feeding seat. Specifically, the needle feeding seat is a rectangular structure, and a needle holder 33 is provided at the center position of the upper end surface of the needle feeding seat, and a vertically arranged pin 34 is placed on the needle holder. A limiting groove 224 is provided on the upper part of one end of the movable block close to the center of the guide rail, and the extension direction of the limiting groove is in the same direction as the extension direction of the second linear guide rail. The two ends of the needle feeding seat are respectively movably arranged on the limiting grooves of the two movable blocks, and the end of the needle feeding seat close to the limiting groove is connected to the conveying seat.

[0083] The movable rod is connected to the end of the needle feeding seat away from the conveying seat, and the movable block extending from the movable rod is located on the other side of the centering mechanism. The end surface of the movable block located near the center of the guide rail and below the limiting groove is provided with an inclined limiting surface 225 and a vertical connecting plane 226, and the limiting surfaces and connecting planes are arranged in sequence along the direction approaching the conveying seat, and the distance between the limiting surfaces of the two movable blocks gradually decreases along the direction approaching the connecting plane.

[0084] The lower part of the needle feeding seat is provided with two limit pins. When the two ends of the needle feeding seat contact the limit grooves on the movable block, the outer peripheral side walls of the two limit pins contact the limit surfaces or connecting planes of the two movable blocks respectively. When the movable rod is driven to move along the extension direction of the second linear guide, the needle feeding seat and the transport seat are driven to move simultaneously along the extension direction of the second linear guide. During the movement of the needle feeding seat, when the limit pin contacts the position with the maximum spacing between the two limit surfaces, the two clamps are in a spliced ​​state. As the needle feeding seat moves, the two clamps gradually separate and the third spring is compressed. When the limit pin contacts the connecting plane, the two clamps open to make way for the insertion pin to be placed between the two placement slots. The needle feeding seat is centrally arranged between the two movable blocks, and by driving the needle feeding seat to move, the limit pin generates a thrust on the limit surface. The movable blocks move in opposite directions at the same time under the thrust of the limit pin, and are synchronously reset by the elastic force of the cylindrical spring.

[0085] Specifically, when the needle feeding seat is in the first position, the two placement slots are both located on the clamping station, the pin is located between the gaps between the two placement slots, and the insulator slot on the conveying plate is located on the material taking station; when the needle feeding seat is in the second position, the two placement slots are both located on the cutting station, the pin is located outside the two placement slots, and the insulator slot on the conveying plate is located on the cutting station and is coaxially arranged with the slot body formed by the two placement slots;

[0086] The cutting mechanism includes two sliding rods 51 vertically arranged on the base, a second spring 52, a support seat 53, a handle mechanism 54 and a blade 55. The sliding rod is sleeved in the second spring and the upper part of the sliding rod extends out of the second spring. The second spring is preferably a cylindrical spring. The support seat is T-shaped, and two through holes are provided at the two ends of the support seat corresponding to the T shape. Linear bearings are respectively provided in the two through holes. The support seat is movably connected to the sliding rod through the linear bearings, and the lower end surface of the support seat rests on the top of the second spring. The support seat is located above the clamping plate, and the T-shaped protrusion corresponding to the support seat faces the clamping plate. The blade is arranged on the lower end surface of the support seat, and the cutting surface of the blade and the contact surface when the two placement slots are spliced ​​are located on the same vertical plane, so that the cutting surface of the blade faces the center of the insulator. The blade cuts downward along the center line of the insulator to split the insulator into two halves. During the cutting process, the clamping plate of the centering mechanism can make way for the blade to avoid the blade from biting and squeezing the insulator during the cutting process, thereby ensuring the cutting effect of the insulator.

[0087] The handle mechanism includes a support 541, which is fixedly arranged on the top of the fixed plate. The support is provided with a handle 542, one end of which is hinged to the support. Specifically, the support is adapted to the horizontal height of the support seat, and one end of the handle is hinged to the top of the support, and the middle position of the handle is located directly above the support seat. A second straight groove is provided in the middle position of the handle, and the support seat is provided with a support column 56 arranged opposite to the support. The support column is provided with a movable pin 57 passing through the second straight groove, and the axial direction of the movable pin is parallel to the axial direction of the hinge between the support and the handle. And the horizontal height of the movable pin is higher than the horizontal height of the hinge axis between the support and the handle. The support column and the movable pin provide a support point for the handle above the support seat, forming a lever force, thereby improving the stability and labor-saving of the cutting operation. When performing the insulator bisection operation, the driving handle is pressed downward to drive the blade on the support seat downward. When the blade is pressed down to the conveyor plate, the blade passes through the knife-leaving groove on the conveyor plate and presses the insulator into the slot body formed by the two placement slots. As the blade continues to press down and begins to bisection the insulator, the blade cuts downward along the knife-leaving groove during the insulator bisection process. Because the clamping blocks on both sides are respectively fixed to the first linear guide rail through the movable blocks, the horizontal force generated by the blade during bisection is greater than the pressure of the third springs on both sides. Therefore, during the bisection process, the clamping blocks will move the bisectioned insulator to the sides to avoid squeezing and deformation of the insulator. After bisection is completed, the blade is lifted with the handle. Because the conveyor plate is still above the clamping block at this time, the conveyor plate can play a role in removing the blade as the blade exits along the knife-leaving groove, preventing the bisectioned insulator from adhering to the blade.

[0088] The linkage mechanism includes a wedge block 61, a mounting plate 62 and a wedge pin sleeve 63. The wedge block is arranged on the side of the conveying seat away from the limit block. A wedge pin reset block 64 is provided on the wedge block. The wedge pin reset block is in a right triangle structure, and the apex of the right triangle corresponding to the wedge pin reset block is set downward, and the hypotenuse of the right triangle corresponding to the wedge pin reset block is set close to the side of the centering mechanism. A vertical reset groove 641 is provided on the wedge pin reset block, and the bottom of the reset groove is inclined. Specifically, the bottom of the reset groove is inclined, which means that the depth of the reset groove gradually decreases from top to bottom.

[0089] The mounting plate is connected to the side wall of the support seat away from the centering mechanism. The mounting plate is arranged opposite the wedge-shaped reset block. The wedge pin sleeve is vertically arranged on the side wall of the mounting plate near the wedge-shaped reset block. The wedge pin sleeve is sequentially provided with a fourth spring 631 and a wedge pin 632 from the inside to the outside, and the wedge pin and the wedge pin sleeve are movably connected. The wedge pin is adapted to the reset groove, and the wedge pin and the reset groove are located on the same vertical plane. On this vertical plane, the distance between the end of the wedge pin and the mounting plate is less than the maximum distance between the bottom of the reset groove and the mounting plate and greater than the minimum distance between the bottom of the reset groove and the mounting plate.

[0090] When the support seat drives the blade downward, the wedge pin is embedded in the reset groove and abuts against the bottom of the reset groove. When the blade is pressed down to the cutting station to complete the cutting of the insulator to be cut, the wedge pin slides out of the reset groove in the vertical downward direction. At the same time, the wedge pin automatically pops out under the action of the fourth spring and is tangent to the inclined surface on the hypotenuse of the right triangle corresponding to the wedge pin reset block. When the handle drives the support seat upward, the blade is reset. The wedge pin reset block moves along the inclined surface of the wedge block with the wedge pin as the fulcrum, thereby driving the conveyor seat to move horizontally until the insulator slot is located at the material removal station. During the reset process of the blade, before the blade leaves the cutting station, the conveyor plate is always above the clamping block to prevent the cut insulator from sticking to the cutter and falling off from the groove. At the same time, the conveyor seat synchronously drives the needle feed seat to move horizontally to the second position to achieve linked reset. The linkage mechanism drives the components to complete multiple tasks simultaneously through one action, thereby improving work efficiency. In the process of multiple action linkage, it also solves the problems of insulator falling off and needle feeding mechanism giving way.

[0091] The clamping mechanism comprises a support 71 and two connecting rods 72 on either side of the two clamping blocks. One end of each connecting rod is fixedly connected to the vertical sidewalls of the two clamping blocks, and the other ends of the two connecting rods are hingedly connected via a pin 73, which is arranged horizontally and perpendicular to the linear guide. The support is vertically arranged and has a first straight slot 74 adapted for the pin. The pin is movably disposed within the first straight slot. The projection of the first straight slot in one direction overlaps the symmetry axis of the two connecting rods, and the one direction is oriented in the same direction as the extension direction of the pin. A handle is provided on the end of the pin away from the hinged end, which extends through the first straight slot to the outside. During clamping, the two insulators cut in half are placed in the two placement grooves respectively, and the pin is located between the two placement grooves. The pin shaft is driven to press downward along the first straight groove so that the two connecting rods move toward each other around the pin shaft at the same time, thereby driving the two clamping blocks to move toward each other, so that the insulators on the two clamping blocks contact the pins on the needle feeding seat at the same time. The insulators are connected to the pins by clamping, thereby realizing automatic clamping between the insulators and the pins. After clamping is completed, the clamping blocks are automatically reset under the action of the bow spring.

[0092] In this embodiment, the support is further provided with a cam, comprising a cam body 75 and a cam handle 751 disposed thereon. A vertical U-shaped slot 711 is provided on the support, into which the cam is movably embedded. The pin extends through each end of the cam, and the cam and the support are hingedly connected by a cam pin. Swinging the cam handle depresses the pin, which drives two connecting rods to move the two clamping blocks toward each other, thereby achieving insertion of the insulator into the contact pin.

[0093] In this embodiment, the gap between the bottom of the pre-installed tube and the upper end surface of the conveying plate is 0.1 mm.

[0094] In this embodiment, a slot guide surface is provided at the slot opening of the insulator slot, and the chamfer parameter corresponding to the slot guide surface is C0.3x15(30)°.

[0095] In this embodiment, a cutting guide surface 242 is provided on both of the splints. The cutting guide surface is located on the upper end surface of the splint close to the center of the guide rail, and the chamfer parameter corresponding to the cutting guide surface is C0.3x30°. The cutting guide surface can guide the blade to prevent the blade from cutting the splint.

[0096] In this embodiment, the conveyor plate is further provided with two knife-clearing grooves 432, each communicating with the insulator. The two knife-clearing grooves are arranged opposite each other and are located on the centerline of the insulator slot. The conveyor plate retrieves material from the retrieving station, places the cut insulator in the insulator slot, and then moves to the unloading station. When the conveyor plate is at the unloading station, the insulator slot and the slot body formed by the two placement grooves are coaxially arranged, and the two knife-clearing grooves and the blade are located on the same vertical plane.

[0097] In summary, the present invention provides an RF connector insulator bisection device, which ensures the centering of the insulator during bisection by setting a centering mechanism. During the bisection process, the clamping block can also give way to the blade of the cutter mechanism to avoid the situation of cutting the knife and squeezing the insulator during the bisection process, thereby ensuring the bisection effect of the insulator. After the bisection of the insulator to be cut is completed, there is no need to remove the material. When the needle feeding mechanism drives the two placement slots to be located at the clamping station, the gap between the pins and the placement slots is directly assembled with the insulator, thereby improving efficiency and ensuring that the two insulators after bisection will not be mis-assembled up and down. By setting a pre-installation mechanism, the automatic material removal and unloading of the insulator to be cut is realized, thereby improving efficiency. By setting a linkage mechanism, the purpose of completing multiple tasks in one action is achieved, and the problems of insulator falling off and needle feeding giving way are solved. In addition, the pre-installation tube, conveying plate, clamping block and needle holder can be replaced according to connectors of different specifications to meet the assembly of different types of pins and insulators.
