Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cable processing equipment, in particular to a coiled shielding layer turning mechanism for coaxial cable. BACKGROUND

[0002] In the automatic manufacturing process of radio frequency coaxial cable assemblies, the processing of the coiled shielding layer at the end of the cable is a key and complex procedure. The coiled shielding layer of the coaxial cable is usually woven into a mesh structure by thin metal wires and is located inside the outer sheath. In order to reliably assemble the connector to the end of the cable, the coiled shielding layer exposed after a section of the outer sheath is stripped needs to be turned over so that it is evenly spread and attached to the fixed clasp or the end of the outer sheath of the cable in the backward direction (i.e., in the direction of the outside of the cable). The purpose of this turning over (or turning) operation is to regularize the coiled layer, enhance the mechanical strength of the end of the cable, and provide a flat transition interface for the subsequent assembly of the connector body.

[0003] At present, the common processing method of this procedure mainly has the following deficiencies: first, for small batches or high flexibility production, it still heavily relies on operators to use hand tools (such as hooks, tweezers) to pick and turn over. This way not only has extremely low efficiency and high labor intensity, but also the uniformity and consistency of the turning over completely depend on individual skills, and problems such as uneven turning over of the metal wires, partial fibers not being turned over or being damaged by excessive stretching, etc. are prone to occur, which directly affects the subsequent assembly quality and the stability of the electrical shielding performance of the product. SUMMARY

[0004] The technical problem solved by the present application is to provide a coiled shielding layer turning mechanism for coaxial cable, which can automatically and efficiently complete the non-destructive turning over of the coiled shielding layer of the coaxial cable by driving the turning brush to simultaneously perform the compound motion of self-rotation around the axis, revolution around the wire, and radial feeding, thereby replacing the defects of uneven and easily damaged manual turning.

[0005] To solve the above technical problems, one technical solution adopted by the present application is to provide a coiled shielding layer turning mechanism for coaxial cable for turning over the coiled shielding layer exposed after stripping the outer sheath, comprising: a turning support installed on a rack; at least one turning brush for contacting and turning over the coiled shielding layer; a self-rotation transmission assembly installed on the turning support and drivingly connected with the turning brush for driving the turning brush to rotate around its own axis; a revolution transmission assembly installed on the turning support and drivingly connected with the turning brush for driving the turning brush to rotate around the end axis of the wire to be processed; and The flanging drive unit is mounted on the frame and connected to the flanging bracket drive. It is used to drive the flanging bracket and the components mounted on it to move in a direction close to or away from the end of the wire.

[0006] Preferably, the self-rotation transmission assembly includes: The self-rotating drive component is fixedly installed on the flange bracket; The self-rotating shaft is connected to the output end of the self-rotating drive component, thereby driving the self-rotating shaft to rotate. The driving bevel gear is installed at the end of the rotating shaft, so that the rotating shaft drives the driving bevel gear to rotate. The driven bevel gear meshes with the driving bevel gear, and a driving synchronizing pulley is mounted on the shaft of the driven bevel gear. Thus, the driving bevel gear drives the driven bevel gear to rotate, and the driven bevel gear drives the driving synchronizing pulley to rotate. The rotating shaft of the flanging brush is equipped with a driven synchronous wheel. The driving synchronous wheel and the driven synchronous wheel are connected by a synchronous belt, so that the driving synchronous wheel drives the driven synchronous wheel to rotate, and in turn the driven synchronous wheel drives the flanging brush to rotate.

[0007] Preferably, the revolution transmission assembly includes a revolution drive component and a revolution sleeve, the revolution drive component is fixedly mounted on the flange bracket, and the revolution sleeve is connected to the output end of the revolution drive component; The revolution sleeve and the rotation axis are coaxially fitted together, and the two can rotate relative to each other; The flanged brush is mounted on the revolution sleeve via the flanged seat.

[0008] Preferably, there are two flanging brushes, which are rotatably connected to the flanging seat through corresponding flanging connecting plates, and the two flanging brushes are arranged opposite each other along their own axial direction.

[0009] Preferably, it also includes a flange opening and closing assembly, which is mounted on the flange bracket and driven to two flange connecting plates, so as to drive the two flange connecting plates to rotate, so that the two flange brushes move closer to each other to clamp the wire or move away from each other to release the wire.

[0010] Preferably, the flange opening and closing assembly includes: The opening and closing drive component is mounted on the flange bracket; The opening / closing linkage is connected to the output end of the opening / closing drive component; and... The sliding plate has two ends that slide in conjunction with the flanged connecting plate. The opening and closing drive unit moves the opening and closing linkage, which in turn moves the opening and closing slide plate, thereby driving the two flange plates to rotate. This causes the two flange brushes to move closer to each other to clamp the wire or move further apart to release the wire.

[0011] Preferably, a bearing is installed on the flange bracket, and the rotation shaft is supported on the flange bracket by the bearing.

[0012] Preferably, the flanging drive component is a linear module driven by a motor.

[0013] The beneficial effects of this invention are as follows: By integrating a self-rotation transmission component that drives the flanging brush to rotate at high speed around its own axis, a revolution transmission component that drives the flanging brush to rotate circumferentially around the cable end axis, and a flanging drive component that controls the radial feed of the flanging brush, a composite motion system is formed. This achieves, for the first time, active, dynamic, and fully automated processing in the braided layer flanging process. The flanging brush generates combing and folding forces during its high-speed self-rotation, and ensures uniform contact and operation with every point on the cable circumference during continuous revolution. Combined with precise radial feed control of the folding depth and force, this enables a gentle, gradual folding of the braided shielding layer from the outside in, effectively avoiding damage to the metal wires caused by excessive force or rough movements. Simultaneously, the synergy of the three motions ensures the uniformity of the folding force in the circumferential and radial directions of the braided layer, allowing the folded braided layer to adhere smoothly and neatly to the retaining ring or outer sheath end, providing an ideal pre-treatment state for the subsequent precision assembly of the connector.

[0014] This fundamentally overcomes the inherent defects of manual operation and simple mechanical devices, such as uneven folding, low efficiency, and easy damage to the braided yarns. The mechanism ensures that the braided shielding layer is neatly, completely, and smoothly folded to the preset position, significantly improving the quality consistency and reliability of the folding process and providing an ideal pre-treatment state for subsequent connector assembly. At the same time, its highly automated design greatly reduces labor intensity and reliance on skilled workers, and can be stably integrated into high-speed automated production lines, significantly improving overall production efficiency and product qualification rate.

However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0023] Unless otherwise specified, physical quantities in formulas should be understood as basic quantities of SI base units, or derived quantities derived from basic quantities through mathematical operations such as multiplication, division, differentiation, or integration.

[0024] Example: refer to Figures 1-3 This embodiment details an automatic assembly device for coaxial cable end connectors, including a wire feeding and cutting mechanism 10. The wire feeding and cutting mechanism 10 simultaneously feeds a large quantity of coiled wire and cuts long wires into smaller segments. A winding mechanism 11 is located on one side of the wire feeding and cutting mechanism, and a wire clamping and conveying mechanism is located between the winding mechanism 11 and the wire feeding and cutting mechanism 10. The winding mechanism 11 aligns the two ends of the smaller wire segments with the same preset orientation to facilitate sequential processing of the ends by subsequent mechanisms. The wire clamping and conveying mechanism transfers the wire cut by the wire feeding and cutting mechanism 10 to the winding mechanism 11, which, in conjunction with the wire feeding and cutting mechanism 10, cuts the wire into the required smaller segments. The wire is a coaxial cable, comprising, from the outside in: an outer sheath, a braided shielding layer, an insulation layer, and a core.

[0025] refer to Figure 2 The wire feeding and cutting mechanism 10 includes a coaxial wire feeder 1001, an upper wire feeder cutter, and a lower wire feeder cutter. The upper and lower wire feeder cutters are arranged opposite each other at the end of the coaxial wire feeder to cut the wire into the required small segments. To facilitate automation, cylinders can be connected to the upper and lower wire feeder cutters, and the relative movement of the upper and lower wire feeder cutters can be controlled by the corresponding cylinders to cut the wire into small segments.

[0026] The following embodiments detail the winding mechanism. It is understood that this mechanism is a key component of the aforementioned automated coaxial cable assembly equipment, used to organize the cut wire segments. Furthermore, as a winding and organizing mechanism for wire segments, it can be fully applied to other automated applications or equipment requiring the orienting and organizing of flexible wire segments.

[0027] refer to Figures 1-3The winding mechanism 11 includes a winding disc 111, winding clamps, multiple outer expansion rods 113, a winding rotation drive assembly, and a winding expansion and contraction drive assembly. The winding clamps are mounted on the winding disc 111 to clamp the end of the wire from the wire feeding and cutting mechanism 10. The winding disc 111 has a slide rail 114, and the outer expansion rods 113 slide in cooperation with the slide rail 114. The winding expansion and contraction drive assembly is connected to the outer expansion rods 113 so that the multiple outer expansion rods 113 expand outwards to open up small sections of wire and avoid the wire from tangling and knotting, and so that the multiple expansion rods contract with each other so that they no longer contact the opened wire. The winding rotation drive assembly is connected to the winding disk 111 and drives the winding disk 111 to rotate. When the winding clamps hold one end of the wire, the winding expansion drive assembly causes the outer expansion rods 113 on the winding disk 111 to expand outwards from each other. The winding rotation drive assembly causes the winding disk 111 to rotate. By controlling the rotation angle of the winding disk 111, the ends of both ends of the wire are in the same orientation, which facilitates the subsequent sequential processing of the ends by various mechanisms.

[0028] The winding clamps can be set in two sets, which can clamp the two ends of the wire respectively, thereby maintaining the position of the two ends of the wire.

[0029] After the wire is wound, the winding expansion and contraction drive component moves, causing multiple outer expansion rods 113 to move closer to each other and contract, so that the outer expansion rods 113 no longer support the small section of wire.

[0030] To ensure the stability of the outer expansion rod 113 sliding on the winding reel 111, a slide rod 115 is fixedly installed on the winding reel 111, and a winding slider 116 is slidably fitted on the slide rod 115. The outer expansion rod 113 is fixedly connected to the winding slider 116, and the winding slider 116 is slidably fitted with the slide rod 115.

[0031] refer to Figure 2 and Figure 3 The winding expansion and contraction drive assembly includes an expansion and contraction drive component 121, an expansion and contraction movable shaft 122, and an expansion and contraction connecting rod 123. The expansion and contraction drive component 121 is fixedly connected to the frame, and its output end is connected to the expansion and contraction movable shaft 122 to drive the shaft to move axially up and down. One end of the expansion and contraction connecting rod 123 is rotatably connected to the upper end of the expansion and contraction movable shaft 122, and the other end is rotatably connected to the winding slider 116. Thus, when the expansion and contraction movable shaft 122 moves upward under the action of the expansion and contraction drive component 121, the winding slider 116 is forced to slide outward through the expansion and contraction connecting rod 123, thereby causing the outer expansion rods 113 to move away from each other and thus expanding the winding wire. When the expansion and contraction movable shaft 122 moves downward under the action of the expansion and contraction drive member 121, the winding slider 116 is forced to slide inward through the expansion and contraction connecting rod 123, so that the outer expansion rods 113 move closer to each other and contract together, thereby detaching from the wire and preparing for the processing of the next wire.

[0032] refer to Figure 2 and Figure 3 The expansion and contraction drive component 121 can be a cylinder or a motor. An expansion and contraction slider 124 is slidably connected to the frame. The expansion and contraction movable shaft 122 is connected to the expansion and contraction slider 124. If the expansion and contraction drive component 121 is a cylinder, the extension and retraction of the cylinder piston rod drives the expansion and contraction slider 124 to slide up and down, thereby driving the expansion and contraction movable shaft 122 to move axially up and down. If the expansion and contraction drive component 121 is a motor, the motor is connected to a lead screw via a coupling. The lead screw is threaded into the expansion and contraction slider 124, thus controlling the up and down movement of the expansion and contraction slider 124 by the rotation of the motor, allowing for more precise control. The expansion and contraction movable shaft 122 can be rotatably connected to the expansion and contraction slider 124, meaning the expansion and contraction movable shaft 122 can rotate around its own axis. Alternatively, a limiting structure can be added to the expansion and contraction slider 124 to prevent the risk of the expansion and contraction movable shaft detaching.

[0033] refer to Figure 3 In order to facilitate the rotational connection between the expansion and contraction linkage 123 and the expansion and contraction movable shaft 122, a hinge ring 125 can be fixedly connected to the expansion and contraction movable shaft 122, so that one end of the expansion and contraction linkage 123 is rotatably connected to the hinge ring 125.

[0034] refer to Figure 2 and Figure 3 The winding rotation drive assembly includes a rotation drive component 131, a winding timing belt 132, and a winding timing pulley. The winding timing pulley is connected to an expansion and contraction shaft 122. The rotation drive component 131 can be a motor. A winding drive wheel 136 is mounted on the rotation drive component 131. The winding timing belt 132 is sleeved on the winding drive wheel 136 and the winding timing pulley, thereby driving the winding timing pulley to rotate. A follower disk 134 is mounted on the winding timing pulley. The follower disk 134 is connected to the winding disc 111 through a connecting rod 135. Thus, the rotation drive component 131 drives the winding timing pulley to rotate, the winding timing pulley drives the follower disk 134 to rotate, and the follower disk 134 drives the winding disc 111 to rotate through the connecting rod 135. As another alternative implementation, the winding synchronous pulley can form a sliding engagement with the expansion and contraction movable shaft 122 through splines, guide keys, etc., so that the winding synchronous pulley can both transmit torque to drive the expansion and contraction movable shaft 122 to rotate and allow the expansion and contraction movable shaft 122 to slide axially (vertically). This can also achieve decoupling of the lifting and rotating motions, so that they do not interfere with each other.

[0035] Additionally, when the winding disc 111 rotates, it will synchronously drive the outer expansion rod 113, the expansion and contraction slider 124, the expansion and contraction connecting rod 123, and the expansion and contraction movable shaft 122 to rotate, without interfering with each other.

[0036] refer to Figure 3 and Figure 4The winding clamp includes a winding fixed claw 1121 and a winding movable claw 1122. The winding fixed claw 1121 is fixedly connected to the skeleton below the winding reel 111. The winding movable claw 1122 is rotatably connected to the winding fixed claw 1121. A first extension plate 11221 extends outward from one side of the winding movable claw 1122. A first spring groove 11211 is provided on the winding fixed claw 1121. A first spring is provided in the first spring groove 11211. One end of the first spring abuts against the first spring groove 11211, and the other end of the first spring abuts against the lower side of the first extension plate 11221, so as to force the clamping point of the winding movable claw 1122 to approach the clamping point of the winding fixed claw 1121, thereby clamping the end of the wire.

[0037] refer to Figure 3 and Figure 4 The winding claw 1122 extends to the other side of the first extension plate 11221, opposite to the winding claw 11222. A first unlocking assembly is also installed on the frame. The first unlocking assembly includes a first unlocking drive 141, an unlocking mounting block 142, and a first cam follower 143. The first unlocking drive 141 is fixedly connected to the frame and can be a cylinder. The unlocking mounting block 142 is connected to the first unlocking drive 141, such as by screws. On the piston rod of the actuator 141, the first cam follower 143 is mounted on the unlocking mounting block 142. When the winding clamp needs to release the wire, the piston rod of the first unlocking drive 141 extends, thereby driving the first cam follower 143 to move upward toward the second extension plate 11222 through the unlocking mounting block 142. Then, the first cam follower 143 pushes against the second extension plate 11222, thereby forcing the clamping point of the winding movable claw 1122 away from the clamping point of the winding fixed claw 1121, thereby releasing the clamped wire.

[0038] For ease of description, this paper establishes the following coordinate system: with the front of the device as the observation angle, the horizontal left and right direction is the X-axis, the horizontal front and back direction is the Y-axis, and the vertical up and down direction is the Z-axis.

[0039] refer to Figures 1-3The wire clamping and handling mechanism includes a Y-axis drive assembly 151, an X-axis drive assembly 152, a Z-axis drive assembly 153, and a wire clamping jaw 154. The Y-axis drive assembly 151 is mounted on the frame, the Z-axis drive assembly 153 is mounted on the Y-axis drive assembly 151, the X-axis drive assembly 152 is mounted on the Z-axis drive assembly 153, and the wire clamping jaw 154 is mounted on the X-axis drive assembly 152. The Y-axis drive assembly 151 drives the Z-axis drive assembly 153 to move in the Y direction, thereby driving the wire clamping jaw 154. The Y-axis drive assembly 153 drives the X-axis drive assembly 152 to move in the Z-axis direction, thereby driving the wire clamping claw 154 to move in the Z-axis direction. The X-axis drive assembly 152 controls the wire clamping claw 154 to move in the X-axis direction. Through the cooperation of the Y-axis drive assembly 151, X-axis drive assembly 152, and Z-axis drive assembly 153, the wire clamping claw 154 moves in the YXZ directions, thereby facilitating the wire clamping claw 154 to move the wire onto the winding reel 111 and to cooperate with the winding clamping claw to clamp and release the wire. The Y-axis drive assembly 151 can be a Y-axis arranged lead screw module or linear motor module, the X-axis drive assembly 152 can be an X-axis arranged cylinder or an X-axis arranged lead screw module or linear motor module, and the Z-axis drive assembly 153 can be a Z-axis arranged cylinder, linear motor module, etc.

[0040] refer to Figure 1 , Figure 5 and Figure 6 A feeding assembly 16 is provided on one side of the winding mechanism 11. The feeding assembly 16 includes a carrier, a second unlocking assembly, and a conveyor line. The carrier is mounted on the conveyor line, which is mounted on the frame. The carrier includes a loading fixing block 1611 and a loading movable block 1612. The loading movable block 1612 is mounted on the loading fixing block 1611 and rotates with it. A second spring groove is provided on the loading fixing block 1611, and a second spring 16111 is provided in the second spring groove. One end of the second spring 16111 abuts against the second spring groove, and the other end of the second spring 16111 abuts against the loading movable block 1612 to force the loading movable block 1612 to abut against the loading fixing block 1611, thereby clamping the wire. When the wire needs to be clamped at both ends and moved to an unused station, the carriers can be set in groups of two, with each group clamping one end of the wire. An arc-shaped groove can be made in the area where the wire is clamped by the material-fixing block 1611 and the material-moving block 1612, so as to match the outer surface of the wire and thus clamp it more stably.

[0041] refer to Figure 5 and Figure 6The second unlocking component includes a second unlocking drive 1621 and a pressure plate 1622. The second unlocking drive 1621 is mounted on the frame and can be a cylinder. The pressure plate 1622 is mounted on the piston rod of the second drive. The second unlocking drive 1621 drives the pressure plate 1622 to move vertically up and down. When the second unlocking drive 1621 drives the pressure plate 1622 to move vertically down, the pressure plate 1622 presses down on one side of the material-carrying movable block 1612 to overcome the elastic force of the second spring 16111 and force the material-carrying movable block 1612 to no longer abut against the material-carrying fixed block 1611 and open up, waiting for the next wire to be placed on the carrier.

[0042] refer to Figure 1 To further improve the level of automation, a wire harness handling device 18 can be set between the feeding assembly 16 and the winding mechanism 11 to move the processed wire on the winding mechanism 11 to the carrier.

[0043] refer to Figure 1 , Figure 5 and Figure 6 A first fixed-length cutting mechanism 19 is also provided along the conveying direction of the conveyor line. The first fixed-length cutting mechanism 19 includes a first fixed-length cutting bracket, a first upper fixed-length cutter 192, and a first lower fixed-length cutter 193. The first fixed-length cutting bracket is mounted on the frame. The first upper fixed-length cutter 192 and the first lower fixed-length cutter 193 are mounted opposite each other on the first fixed-length cutting bracket and slide in cooperation with the first fixed-length cutting bracket. When the end of the wire is between the first upper fixed-length cutter 192 and the first lower fixed-length cutter 193 under the drive of the carrier, the first upper fixed-length cutter 192 and the first lower fixed-length cutter 193 move closer to each other and cut the end of the wire, thereby ensuring the consistency of the position of all wire ends and ensuring further processing of the wire by subsequent workstations. A cylinder can be installed on the first fixed-length cutting bracket to drive the corresponding first upper fixed-length cutter 192 and first lower fixed-length cutter 193 to cut the end of the wire.

[0044] To further ensure the stability of the wire head position when it is cut, and to support and fix the wire end, a first fixed-length cutting and straightening clamp 194 can be installed on the first fixed-length cutting bracket. When the wire is cut, the first fixed-length cutting and straightening clamp 194 stabilizes the position of the wire end and ensures the cutting effect.

[0045] refer to Figure 1 and Figure 5An outer sheath stripping mechanism 20 is also provided along the conveying direction of the conveyor line. The outer sheath stripping mechanism 20 is arranged on one side of the first fixed-length cutting mechanism 19. The outer sheath stripping mechanism 20 includes a first wire stripper 201 and a first wire stripping clamping assembly. The first wire stripping clamping assembly includes a first wire stripping lower clamping block, a first wire stripping bracket 2024, and a first wire stripping upper clamping block 2025. The first wire stripping lower clamping block is fixedly connected to the frame. The first wire stripping bracket 2024 is installed on the frame. The first wire stripping upper clamping block 2025 is installed on the first wire stripping bracket 2024. A cylinder can be installed on the first wire stripping bracket 2024, so that the first wire stripping upper clamping block 2025 is connected to the cylinder. Then, the cylinder moves to drive the first wire stripping upper clamping block 2025 to move closer to or away from the first lower support plate. The first wire stripper 201 is mounted on the linear module, which is mounted on the frame. When the outer sheath of the wire is stripped to expose the braided shielding layer, the carrier moves the end of the wire to the designated position. The first stripping upper clamping block 2025 approaches the first stripping lower clamping block and clamps and fixes the end of the wire. The linear module drives the first wire stripper 201 to approach the end of the wire, thereby stripping the outermost outer sheath of the wire end to expose the mesh braided shielding layer made of fine metal wires, thus making preliminary preparations for the assembly between the cable and the connector.

[0046] refer to Figure 1 , Figures 7-9 A fixed retaining ring crimping mechanism 30 is also provided along the conveying direction of the conveyor line. The fixed retaining ring crimping mechanism 30 is located on one side of the outer sheath stripping mechanism 20. The fixed retaining ring crimping mechanism 30 is used to crimp the fixed retaining ring to the preset setting at the end of the wire. The fixed retaining ring is riveted to the exposed part of the braided shielding layer and the end of the outer sheath, thereby increasing the support strength of the wire end, and thus providing basic support strength for the subsequent assembly of the wire and connector.

[0047] refer to Figures 7-9 The retaining ring pressing mechanism 30 includes a retaining ring press 301, a retaining ring pressing lower die 302 connected to the retaining ring press 301, and a retaining ring pressing upper die 303 connected to the retaining ring press 301 and arranged opposite to the retaining ring pressing lower die 302. The retaining ring pressing lower die 302 has a concave arc groove for supporting the retaining ring on the material strip. The concave arc groove stabilizes the position of the retaining ring on the material strip on the retaining ring pressing lower die 302, ensuring the consistency of the position of the retaining ring on the wire. The retaining ring pressing upper die 303 and retaining ring pressing lower die 302 press the retaining ring onto the wire and punch the retaining ring away from the carrier belt.

[0048] refer to Figures 7-9One side of the fixed retaining ring pressing mechanism 30 is provided with a first wire feeding mechanism and a third unlocking component. The first wire feeding mechanism includes a wire feeding drive component 311 and a first wire feeding gripper 312. The wire feeding drive component 311 is mounted on the frame. The wire feeding drive component 311 drives the first wire feeding gripper 312 to move in the Y and Z directions, thereby clamping the end of the wire and sending the end of the wire to the concave arc groove of the retaining ring pressing die 302. The wire feeding drive component 311 can be a cylinder or linear module with Y and Z directions arranged together, as long as it can drive the first wire feeding gripper 312 to move and send the wire to the concave arc groove of the retaining ring pressing die 302.

[0049] refer to Figure 7 The third unlocking component includes a third unlocking bracket 321, a third unlocking drive 322, and a third cam follower 323. The third unlocking bracket 321 is mounted on the snap ring press 301 or the frame. The third unlocking drive 322 is mounted on the third unlocking bracket 321 in the Z direction. The third cam follower 323 is mounted on the third unlocking drive 322. Thus, when the first wire feeding mechanism needs to move the wire into the concave arc groove of the snap ring pressing die 302, the third unlocking drive 322 actuates to cause the third cam follower 323 to press down on one end of the material loading block 1612 of the carrier, so that the carrier no longer clamps the wire, and the first wire feeding mechanism can move the wire.

[0050] refer to Figure 1 and Figure 10 An outer skin removal mechanism 33 is also provided along the conveying direction of the conveyor line. The outer skin removal mechanism 33 is arranged on one side of the fixed retaining ring pressing mechanism. The outer skin removal mechanism 33 includes an outer skin removal Y-direction drive component 331, an outer skin removal gripper 332, an outer skin removal lower pressing block 333, an outer skin removal upper pressing block 334, and an outer skin removal bracket 335. The outer skin removal bracket 335 is set on the frame. The outer skin removal Y-direction drive component 331 is Y-directly mounted on the outer skin removal bracket 335. The outer skin removal Y-direction drive component 331 can be a cylinder or a linear module. The outer skin removal gripper 332 can be a finger cylinder with grippers. The outer skin removal upper pressing block 334 and the outer skin removal lower pressing block 335 are also included. The pressure blocks 333 are arranged opposite each other on the outer sheath removal bracket 335. The upper outer sheath removal pressure block 334 and the lower outer sheath removal pressure block 333 are respectively connected to cylinders, thereby driving the upper outer sheath removal pressure block 334 and the lower outer sheath removal pressure block 333 to move closer to each other, clamping the section of outer sheath that has been cut by the first wire stripper 201 but has not yet detached from the wire, and under the action of the outer sheath removal Y-direction drive member 331, the section of outer sheath is detached from the wire, thereby further preparing for the assembly between the cable and the connector.

[0051] The following embodiments detail the braided flanging mechanism. This mechanism is the core workstation in the aforementioned automated equipment specifically designed for processing coaxial cable braided shielding layers. Furthermore, as a flanging mechanism for coaxial cable braided shielding layers, it can also independently form a universal flanging device for cylindrical surface braided layers or similar structures, applicable to other process scenarios.

[0052] refer to Figure 1 , Figures 11-13 A weaving and flanging mechanism 34 is also provided along the conveying direction of the conveyor line, and the weaving and flanging mechanism 34 is arranged on one side of the outer skin removal mechanism 33. The braided flanging mechanism 34 includes a flanging bracket 341, a flanging brush 342, a flanging seat 343, and a self-rotation transmission assembly. The flanging bracket 341 is mounted on the frame, the flanging seat 343 is mounted on the flanging bracket 341, the flanging brush 342 is arranged on the flanging seat 343 and rotates with the flanging seat 343, and the self-rotation transmission assembly is mounted on the flanging seat 343 and connected to the flanging brush 342. The self-rotation transmission assembly is used to drive the flanging brush 342 to rotate around its own axis, so that the metal wires on the mesh braided shielding layer made of fine metal wires are folded under the contact drive of the flanging brush 342, and the folded part of the metal wires is folded onto the fixed retaining ring. This further enhances the support strength of the wire end, and also straightens the braided shielding layer, and exposes the insulation layer under the braided shielding layer, thus further preparing for the assembly of the cable wire and the main body components.

[0053] refer to Figures 11-13 The rotation transmission assembly includes a rotation drive 3441, a rotation shaft 3442, a driving bevel gear 3443, and a driven bevel gear 3444. The rotation drive 3441 is fixedly mounted on the flange bracket 341. The output end of the rotation drive 3441 is connected to the rotation shaft 3442 through gear transmission, thereby driving the rotation drive 3441 to rotate the rotation shaft 3442 around its own axis.

[0054] The driving bevel gear 3443 is installed at the end of the rotating shaft 3442, and the driven bevel gear 3444 meshes with the driving bevel gear 3443. The driven bevel gear 3444 rotates and is connected to the flange seat 343 via the rotating shaft.

[0055] A drive synchronous pulley 3445 is fixedly connected to the rotating shaft, and a driven synchronous pulley 3446 is installed on the rotating shaft of the flanged brush 342. A synchronous belt is fitted on the drive synchronous pulley 3445 and the driven synchronous pulley 3446, so that the drive synchronous pulley 3445 and the driven synchronous pulley 3446 are connected by the synchronous belt.

[0056] Therefore, the rotation drive 3441 drives the rotation shaft 3442 to rotate. The rotation of the rotation shaft 3442 drives the driving bevel gear 3443 to rotate. The driving bevel gear 3443 drives the driven bevel gear 3444 to rotate. The driven bevel gear 3444 drives the driving synchronous pulley 3445 to rotate. The driving synchronous pulley 3445 drives the driven cylindrical gear to rotate. The driven bevel gear 3444 drives the flanging brush 342 to rotate. Finally, the flanging brush 342 is driven to rotate at high speed around its own axis, so that the high-speed rotating brush can fold the woven shielding layer. The rotation drive 3441 can be a motor. The motor shaft is connected to a gear, and the gear is connected to the rotation shaft 3442, so that the motor drives the rotation shaft 3442 to rotate. To better support the rotation shaft 3442, a bearing can be installed on the flange bracket 341, and the rotation shaft 3442 is mounted on the bearing, so that the flange bracket 341 stably supports the rotation of the rotation shaft 3442.

[0057] Since the wire is cylindrical and the braided shielding layer is distributed around the circumference of the wire, in order to fully fold the exposed braided shielding layer, a revolution transmission component is also provided on the folding bracket 341. The revolution transmission component causes the folding brush 342 to rotate around the axial direction of the end of the wire to be processed, so that the folding brush 342 can fully fold the braided shielding layer.

[0058] refer to Figures 11-13 The revolution transmission assembly includes a revolution drive component 351 and a revolution sleeve 352. The revolution drive component 351 is fixedly installed on the flanging bracket 341. The revolution drive component 351 is connected to the revolution sleeve 352 through gear transmission, thereby driving the revolution sleeve 352 to rotate around its own axis. In order to further improve the compactness of the braiding flanging mechanism 34, and to cooperate with the rotation transmission assembly to realize the revolution of the flanging brush 342, which can rotate around its own axis and rotate around the axis of the end of the wire, the revolution sleeve 352 is sleeved on the rotation shaft 3442. The revolution sleeve 352 and the rotation shaft 3442 are coaxially arranged. The flange seat 343 is bolted to the revolving sleeve 352. The flange brush 342 is eccentrically mounted on the flange seat 343. Thus, the revolving drive component 351 drives the revolving sleeve 352 to rotate, the revolving sleeve 352 drives the flange seat 343 to rotate, and the flange seat 343 drives the flange brush 342 to rotate. In turn, the flange seat 343 drives the flange brush 342 to revolve around the axis of the wire end, so that the flange brush 342 can contact all exposed braided shielding layers and perform flange treatment on them.

[0059] refer to Figure 11To control the relative position of the braiding and flanging mechanism 34 and the wire, and to ensure the flanging effect of the braided shielding layer, a flanging drive unit 353 is installed on the frame. The flanging drive unit 353 is a linear module driven by a motor. The flanging bracket 341 is installed on the flanging drive unit 353. The flanging drive unit 353 can be a linear module of a motor arranged in the Y direction. Thus, the flanging drive unit 353 controls the braiding and flanging mechanism 34 to move closer to or further away from the end of the wire, and then coordinates the feeding action with the flanging brush 342 to fold the braided shielding layer. The flanging drive unit 353 is used to control the folding depth and force. When the flanging brush 342 performs the folding operation, the flanging drive unit 353 works in conjunction with the self-rotation transmission component and the revolution transmission component. The synergy of these three movements ensures the uniformity of the folding force in the circumferential and radial directions of the braided layer, allowing the folded braided layer to be flat and neatly attached to the retaining ring or the end of the outer sheath. This provides an ideal pre-treatment state for the subsequent precision assembly of the connector and enables a flexible folding of the braided shielding layer from the outside in with progressive force, effectively avoiding damage to the metal wires caused by excessive force or rough movements.

[0060] refer to Figure 11 and Figure 12 To further ensure the efficiency and effectiveness of folding the woven shielding layer, two sets of folding brushes 342 can be arranged accordingly. Similarly, two driven bevel gears 3444 can be provided, each connected to a corresponding folding brush 342. The folding brushes 342 are connected to the folding seat 343 via folding connecting plates 364. One end of the folding connecting plate 364 is rotatably engaged with the folding seat 343, and the folding brushes 342 and the driven synchronous wheel 3446 are rotatably connected to the other end of the folding connecting plate 364. The two folding connecting plates 364 are arranged in opposite directions.

[0061] refer to Figures 11-13To control the two flange connecting plates 364 so that the ends of the flange brushes 342 are mounted on them move closer or further apart, thereby achieving the effect of the flange brushes 342 clamping the wire or disengaging from the wire, a flange opening and closing assembly is provided on the flange bracket 341. The flange opening and closing assembly includes an opening and closing drive component 361, an opening and closing connecting rod 362, and an opening and closing slide plate 363. The opening and closing drive component 361 is mounted on the flange bracket 341 and can be a cylinder. The piston rod of the opening and closing drive component 361 is connected to the opening and closing connecting rod 362. One end of the connecting rod 362 is connected to the opening / closing slide plate 363. The two ends of the opening / closing slide plate 363 are slidably engaged with elongated holes on the corresponding flange connecting plates 364 via screws. The movement of the opening / closing slide plate 363 is controlled by the extension and retraction of the piston rod of the opening / closing drive component 361, causing the two flange connecting plates 364 to rotate. This causes the ends of the flange connecting plates 364 away from the flange seat 343 to move closer or further apart, thereby causing the two flange brushes 342 to move closer or further apart. This allows the flange brushes 342 to contact the braided shielding layer, causing the braided shielding layer to fold or detach from it. The working axis of the flange brushes 342 and the rotation axis of the orbital sleeve 352 are in two different planes in space, but their directions are perpendicular to each other.

[0062] refer to Figure 11 In order to facilitate the movement of the wire and cooperate with the braiding and flanging mechanism 34 to process the wire, a flanging clamp 37 can be provided on one side of the braiding and flanging mechanism 34. The end of the wire is clamped and fixed by the flanging clamp 37 and moved to the designated position.

[0063] refer to Figure 1 An insulation stripping mechanism 38 is also provided along the conveying direction of the conveyor line. The insulation stripping mechanism 38 is arranged on one side of the braiding and flanging mechanism 34. The insulation stripping mechanism 38 includes a second wire stripper and a second wire stripping clamping assembly. The second wire stripping clamping assembly includes a second wire stripping lower clamping block, a second wire stripping bracket, and a second wire stripping upper clamping block. The second wire stripping lower clamping block is fixedly connected to the frame. The second wire stripping bracket is installed on the frame. The second wire stripping upper clamping block is installed on the second wire stripping bracket. A cylinder can be installed on the second wire stripping bracket so that the second wire stripping upper clamping block is connected to the cylinder. Then, the cylinder moves to drive the second wire stripping upper clamping block closer to or away from the second lower support plate. The second wire stripper is mounted on a linear module, which is mounted on a frame. When stripping the insulation of the wire to expose the core, the carrier moves the end of the wire to a designated position. Then, the upper clamping block of the second stripper approaches the lower clamping block of the second stripper to clamp and fix the end of the wire. The linear module drives the second wire stripper to approach the end of the wire, thereby stripping the insulation from the end of the wire to expose the core, thus further preparing for the assembly of the cable and the center contact. The structure of the insulation stripping mechanism 38 is the same as that of the outer sheath stripping mechanism 20.

[0064] A second fixed-length cutting mechanism is also provided along the conveying direction of the conveyor line. This mechanism is located on one side of the insulation stripping mechanism 38 and includes a second fixed-length cutting bracket, a second upper fixed-length cutter, and a second lower fixed-length cutter. The second fixed-length cutting bracket is mounted on the frame, and the second upper and lower fixed-length cutters are mounted opposite each other on the bracket and slide in cooperation with it. When the wire core is positioned between the second upper and lower fixed-length cutters under the drive of the carrier, the cutters approach each other and cut the end of the wire core, ensuring the consistency of the position of all exposed wire core ends. This facilitates further processing of the wire in subsequent workstations, namely, the riveting between the center contact and the wire core. A cylinder can be installed on the second fixed-length cutting bracket to drive the corresponding second upper and lower fixed-length cutters to cut the end of the wire core. The second fixed-length cutting mechanism has the same structure as the first fixed-length cutting mechanism 19.

[0065] To further ensure the stability of the wire head position during cutting, a second fixed-length cutting and straightening jaw can be installed on the second fixed-length cutting bracket to support and fix the wire end. When cutting the wire core, this second fixed-length cutting and straightening jaw stabilizes the position of the wire end, ensuring the cutting effect. The structure of the second fixed-length cutting and straightening jaw is the same as that of the first fixed-length cutting and straightening jaw 194. refer to Figures 14-17 A contact riveting mechanism 40 is also provided along the conveying direction of the conveyor line. The contact riveting mechanism 40 is used to rivet the center contact to the exposed core of the wire. The contact riveting mechanism 40 is arranged on one side of the second fixed-length cutting mechanism. The contact riveting mechanism 40 includes a contact press 407 and a contact riveting assembly disposed on the contact press 407. The contact riveting assembly includes a first riveting base 401, a first riveting slider 402, a first riveting upper blade 403, a first riveting lower blade 404, and a first riveting wedge 405. The first riveting base 401 is mounted on a frame and has a first riveting groove that mates with the first riveting slider 402. The first riveting slider 402 slides in conjunction with the first riveting groove, which restricts the first riveting slider 402 to slide only in the Z-direction (i.e., up and down). The first riveting lower blade 404 is bolted to the first riveting slider 402, so the first riveting lower blade 404 moves up and down with the first riveting slider 402. The first riveting upper blade 403 is mounted on a contact press 407, so the first riveting upper blade 403 moves toward or away from the first riveting lower blade 404 under the action of the contact press 407, thereby riveting the center contact onto the wire core.

[0066] One end of the first riveting wedge 405 has a first pushing inclined surface 4051. The first riveting slider 402 has a first wedge opening 4021 that mates with the first pushing inclined surface 4051 of the first riveting wedge 405. The first riveting wedge 405 slides in contact with the first wedge opening 4021 of the first riveting slider 402 through the first pushing inclined surface 4051. The first riveting wedge 405 slides in contact with the first riveting base 401, which limits the movement of the first riveting wedge 405 and improves the stability of its movement. The first riveting lower blade 404 has a first lower jaw for supporting the riveting of the center contact member, and the first riveting upper blade 403 has a first upper jaw for riveting the center contact member onto the wire core. The first riveting lower blade 404 supports the riveting of the center contact member and the wire core through the first lower jaw. A first riveting drive 406 is mounted on the frame. The first riveting drive 406 can be a cylinder. The first riveting drive 406 is arranged in the Y direction, so that the first riveting wedge 405 approaches the first riveting slider 402 and pushes the first riveting slider 402 to rise, so that the first riveting cutter 404 reaches the riveting position to support the riveting action. When the first riveting wedge 405 moves away from the first riveting slider 402, the first riveting slider 402 falls without being subjected to external force, so that the first riveting cutter 404 resets to the waiting position, providing clearance space before the center contact member reaches the riveting position.

[0067] refer to Figure 14 and Figure 17The contact component riveting mechanism 40 also includes a contact component rotating mechanism 41 mounted on one side of the contact component press 407. The main shaft of the contact component rotating mechanism 41 is connected to a contact component picking and placing mechanism. The contact component picking and placing mechanism includes a contact component picking and placing mounting plate 421 connected to the main shaft, a contact component driving component 422 mounted on the contact component picking and placing mounting plate 421, and a contact component picking claw connected to the contact component driving component 422. The contact component driving component 422 controls the opening and closing of the contact component picking claw, thereby picking and placing the center contact component and moving the center contact component to a designated position. The contact component driving component 422 can be a cylinder. The contact component rotating mechanism 41 can be a ZR module, which is an existing drive module whose main shaft can move up and down in the Z direction and rotate around its own axis. That is, the contact component rotating mechanism 41 adjusts the orientation and Z-direction height of the contact component picking claw through the contact component picking and placing mounting plate, thereby moving the center contact component to a designated position through the contact component picking claw, and then placing the center contact component on the wire core. Depending on actual needs, a first drive device 4246 that drives the contact component picking claw to move horizontally can be horizontally mounted on the contact component picking mounting plate 421. This, in conjunction with the contact component rotation mechanism 41, enables movement control of the contact component picking claw in the XYZ directions, thereby facilitating the movement of the contact component picking claw from the carrier tape to the wire core. The first drive device 4246 can be a cylinder or a linear motor module, etc.

[0068] refer to Figure 17 The contact member gripper includes a first upper clamping block 424 and a first lower clamping block 425. During clamping, the center contact member is accommodated in the receiving space formed by the clamping portions of the first upper clamping block 424 and the first lower clamping block 425, thereby clamping the center contact member. Because the center contact member is small, in order to ensure the stability of the relative position between the first upper clamping block 424 and the first lower clamping block 425, a first limiting groove 4241 can be opened on the side of the first upper clamping block 424 facing the first lower clamping block 425. A first limiting block extends from the side of the first lower clamping block 425 facing the first upper clamping block 424. The first limiting block can extend into the first limiting groove 4241 and slides with the first limiting groove 4241, thereby stabilizing the position between the first upper clamping block 424 and the first lower clamping block 425 and improving the stability of the position between the first upper clamping block 424 and the first lower clamping block 425.

[0069] refer to Figure 14 A contact component cutting device 43 is also provided on one side of the contact component riveting mechanism 40. The contact component cutting device 43 is used to cut off the center contact component on the material strip so that the contact component picking claw can take away the center contact component.

[0070] refer to Figure 14 and Figure 17When the contact component picking claw clamps the center contact component on the material strip, the contact component cutting device 43 cuts the center contact component on the material strip, separating the center contact component from the material strip. Then, with the cooperation of the contact component rotating mechanism 41, the contact component driving device 422, and other driving devices, the contact component picking claw moves the riveting point of the center contact component opening to the position of contact with the wire core, so that the center contact component reaches the riveting position. Then, the first riveting driving device 406 moves the first riveting wedge 405 close to the first riveting slider 402 and pushes the first riveting slider 402 up, so that the first riveting lower blade 404 reaches the riveting position. At this time, the first lower jaw supports and positions the center contact component. Then, the contact component press 407 moves to make the first riveting upper blade 403 rush towards the first riveting lower blade 404, so that the center contact component is riveted to the wire core. Then, the contact component press 407 resets with the first riveting upper blade 403, thus completing the riveting of the center contact component and the wire core.

[0071] refer to Figure 14 To further ensure the accuracy of the wire and core positions, thereby aligning the crimping point of the center contact with the core, the contact crimping mechanism 40 also includes a crimping positioning assembly. This assembly includes a first positioning gripper 441, a first positioning auxiliary gripper 442, and a first positioning drive 443. The first positioning drive 443 is mounted on the frame and can be a finger cylinder. The first positioning gripper 441 is mounted on the first positioning drive 443 and is used to grip the end of the wire. The first positioning auxiliary gripper 442 is screwed to the end of the first positioning gripper 441 and is used to clamp the exposed core, thus ensuring the accuracy of the core position and, consequently, the alignment of the center contact with the core, thereby guaranteeing the crimping quality between the center contact and the core.

[0072] The following embodiments detail the assembly mechanism between the main body and the center contact, the core of which is formed by the main body riveting mechanism 45 and the auxiliary guide assembly working together. In the aforementioned automated assembly equipment, this mechanism is specifically designed to solve the millimeter-level precision mating problem between the main body and the center contact. Furthermore, as an assembly mechanism for the main body and center contact of a coaxial cable connector, its principle can also be applied to all precision assembly fields requiring the high-precision fitting of a first micro-sleeve type part to a second micro-pin type part.

[0073] refer to Figures 18-26 A main body riveting mechanism 45 is also provided along the conveying direction of the conveyor line. The main body riveting mechanism 45 is used to fit and rivet the prefabricated main body onto the end of the wire and cooperate with the center contact member. The main body riveting mechanism 45 is arranged on one side of the contact member riveting mechanism 40. The main body riveting mechanism 45 includes a main body press 451 and a main body riveting assembly disposed on the main body press 451.

[0074] refer toFigures 19-22 The main riveting assembly includes a second riveting base 453, a second riveting slider 454, a second upper riveting blade 455, a second lower riveting blade 456, and a second riveting wedge 457. The second riveting base 453 is mounted on the frame and has a second riveting groove that mates with the second riveting slider 454. The second riveting slider 454 slides in the second riveting groove, which restricts the second riveting slider 454 to slide only in the Z-direction (i.e., up and down). The second lower riveting blade 456 is bolted to the second riveting slider 454, so the second lower riveting blade 456 moves up and down with the second riveting slider 454. The second upper riveting blade 455 is mounted on the main press 451, so the second upper riveting blade 455 moves toward or away from the second lower riveting blade 456 under the drive of the main press 451, thereby passing the main body through the center contact on the wire core and riveting it to the end of the wire.

[0075] The second riveting wedge 457 has a second pushing inclined surface 4571 at one end, and the second riveting slider 454 has a second wedge opening 4541 that mates with the second pushing inclined surface 4571 of the second riveting wedge 457. The second riveting wedge 457 slides in contact with the second wedge opening 4541 of the second riveting slider 454 through the second pushing inclined surface 4571. The second riveting wedge 457 slides in contact with the second riveting base 453, which limits the movement of the second riveting wedge 457 and improves the stability of its movement. The second riveting lower blade 456 has a second lower jaw for supporting the riveting of the main body, and the second riveting upper blade 455 has a second upper jaw for riveting the main body onto the end of the wire. The second riveting lower blade 456 supports the riveting of the main body and the outer sheath of the wire through the second lower jaw. A second riveting drive 458 is mounted on the frame. The second riveting drive 458 can be a cylinder. The second riveting drive 458 is arranged in the Y direction, so that the second riveting wedge 457 approaches the second riveting slider 454 and pushes the second riveting slider 454 to rise, so that the second riveting cutter 456 reaches the riveting position to support the riveting action. It also moves the second riveting wedge 457 away from the second riveting slider 454 so that the second riveting slider 454 is not subjected to external force and falls, so that the second riveting cutter 456 resets to the waiting position, providing clearance space before the main body reaches the riveting position.

[0076] refer to Figures 18-20The main body riveting mechanism 45 also includes a main body rotation mechanism 46 mounted on one side of the main body press 451. The main body rotation mechanism 46 has a main body picking and placing mechanism connected to its main shaft. The main body picking and placing mechanism includes a main body picking mounting plate 471 connected to the main shaft, a main body drive component 472 mounted on the main body picking mounting plate 471, and a main body picking claw connected to the main body drive component 472. The main body drive component 472 controls the opening and closing of the main body picking claw, thereby picking up and placing the main body and moving the main body to a designated position. The main body drive component 472 can be a cylinder. The main body rotation mechanism 46 can be a ZR module, which is an existing drive module whose main shaft can move up and down in the Z direction and rotate around its own axis. That is, the main body rotation mechanism 46 adjusts the orientation and Z-axis height of the main body picking claw through the main body picking mounting plate 471, thereby moving the main body to a designated position and placing the main body on the wire core. Depending on actual needs, a second drive device 474 can be horizontally mounted on the main body picking mounting plate 471 to drive the main body picking claw to move horizontally. The main body driving component 472 is mounted on the second drive device 474. Thus, the second drive device 474 and the main body driving component 472, together with the main body rotation mechanism 46, realize the movement control of the main body picking claw in the XYZ directions, thereby facilitating the movement of the main body picked up from the carrier tape to the wire core. The second drive device 474 can be a cylinder or a linear motor module, etc.

[0077] refer to Figure 19 , Figure 20 , Figure 23 , Figure 24The main gripper includes a second upper clamping block 4731 and a second lower clamping block 4732. One end of the second lower clamping block 4732 extends to a support block 47321. The upper surface of the support block 47321 is provided with a first contouring groove 47322 that mates with the lower surface of one end of the main body to be riveted. The second upper clamping block 4731 is provided with a second contouring groove 47311 facing the second lower clamping block 4732. When the main gripper clamps the main body, the lower surface of the non-riveted end of the main body is in contact with the first contouring groove 47322, thereby stabilizing the position of the main body on the second lower clamping block 4732. The upper surface of the non-riveted end of the main body is in contact with the second contouring groove 47311, thereby clamping the main body through the cooperation of the second upper clamping block 4731 and the second lower clamping block 4732. Because the main body part is small in size, in order to make the second contour groove 47311 of the second upper clamping block 4731 and the first contour groove 47322 of the second lower clamping block 4732 closer together to clamp the main body, a second limiting groove 47312 is provided on the second upper clamping block 4731. When the second upper clamping block 4731 and the second lower clamping block 4732 approach each other, the second lower clamping block 4732 can enter the lower second limiting groove 47312, and the second lower clamping block 4732 cooperates with the second limiting groove 47312. Thus, while satisfying the requirement that the second upper clamping block 4731 and the second lower clamping block 4732 can approach each other to the greatest extent, the stability between the relative positions of the second upper clamping block 4731 and the second lower clamping block 4732 is stabilized by the limiting cooperation between the second lower clamping block 4732 and the second limiting groove 47312. The second lower clamping block 4732 can be fixedly connected to the main body material handling mounting plate 471. The main body driving component 472 is only connected to the second upper clamping block 4731, so that only the second upper clamping block 4731 is moved to realize the opening and closing between the second upper clamping block 4731 and the second lower clamping block 4732, thereby clamping or releasing the main body more stably, without affecting the subsequent cooperation of the auxiliary guiding components.

[0078] refer to Figure 18 A main body cutting device 48 is also provided on one side of the main body riveting mechanism 45. The main body cutting device 48 is used to cut off the main body on the material strip so that the main body picking claw can take away the center contact part.

[0079] Given the small size of both the center contact and the main body, and the fact that the main body needs to be assembled with the center contact on the wire core when installed at the end of the wire (i.e., the center contact needs to be inserted into the coaxial hole of the insulator in the main body to form a coaxial cable female connector), if the main body is directly inserted into the center contact through the coaxial hole, extremely high alignment precision is required due to the small size of both the main body and the center contact. Otherwise, the center contact may not be able to be accurately inserted into the coaxial hole of the main body, resulting in misalignment between the center contact and the main body, which could damage the parts or prevent the assembly of the main body and the center contact from being completed. Only when the main body and the center contact are properly assembled can the main body be riveted to the wire.

[0080] Therefore, the main material handling claw is equipped with an auxiliary guiding component, for reference. Figure 20 , Figures 23-26 The auxiliary guiding assembly includes an auxiliary drive component 491, an extension column 492, and a docking pin 493. The auxiliary drive component 491 is mounted on the main body's material handling mounting plate 471. The auxiliary drive component 491 can be a cylinder. The extension column 492 is connected to the piston rod of the auxiliary drive component 491. The docking pin 493 is connected to the extension column 492, and the docking pin 493 and the extension column 492 can be integrally formed. The second lower clamping block 4732 has a through hole. The extension column 492 slides with the second lower clamping block 4732 through the through hole, thereby adjusting the extension length of the docking pin 493. The docking pin 493 cooperates with the center contact component, so that the docking pin 493 can be inserted into the insertion hole of the center contact component to guide the assembly docking between the center contact component and the main body.

[0081] refer to Figure 19 and Figure 20 To improve the certainty and consistency of the center contact position and facilitate the insertion of the docking pin 493 into the center contact's socket, thereby guiding the assembly between the center contact and the main body, an auxiliary positioning assembly is also provided on the frame. The auxiliary positioning assembly includes a wire positioning assembly and a contact docking assembly. The wire positioning assembly includes a second positioning gripper 501 and a second positioning drive 503. The second positioning drive 503 is mounted on the frame and can be a finger cylinder. The second positioning gripper 501 is mounted on the second positioning drive 503 and is used to grip the end of the wire, thereby initially fixing and positioning the position of the wire end.

[0082] refer to Figure 19 , Figure 20 , Figure 23 , Figure 24 , Figure 25 , Figure 26The contact docking assembly includes a third positioning gripper, an auxiliary docking block, and a third positioning drive 512. The third positioning drive 512 is mounted on the frame and can be a finger cylinder. The third positioning gripper is mounted on the third positioning drive 512 and is used to clamp the position of the center contact. The auxiliary docking block is mounted on the third positioning gripper. When the body approaches the center contact, the auxiliary docking block guides the docking pin 493 to insert into the socket of the center contact to guide the position of the center contact relative to the body.

[0083] refer to Figures 19-25 The third positioning gripper includes a left gripping arm 5111, a right gripping arm 5112, a left gripping block 5113, and a right gripping block 5114. The left gripping blocks 5113 and 5114 are distributed on the corresponding left gripping arms 5111 and 5112. The left gripping blocks 5113 and 5114 have contoured through grooves 5115 that mate with the outer surface of the center contact member. When the left gripping block 5113 and the right gripping block 5114 are joined together, the contoured through grooves 5115 form contoured through holes and can fit against the outer surface of the center contact member to clamp and radially constrain the center contact member. The left gripping arms 5111 and 5112 are mounted on the third positioning drive member 512, which causes the left gripping arms 5111 and 5112 to open and close relative to each other.

[0084] The auxiliary docking blocks include a left docking block 521 and a right docking block 522. The left docking block 521 is installed on the side of the left clamping block 5113 near the main body's picking claw, and the right docking block 522 is installed on the side of the right clamping block 5114 near the main body's picking claw. The left docking block 521 and the right docking block 522 have opposite docking slots 524. The docking slots 524 are connected to the end of the center contact member away from the riveting area and can restrict the position of the end of the center contact member, thereby stabilizing the position of the end hole of the center contact member and facilitating the insertion of the docking pin 493 into the insertion hole of the center contact member.

[0085] refer to Figure 25 and Figure 26 When the left clamping block 5113 and the right clamping block 5114 merge, the docking slots 524 on the left docking block 521 and the right docking block 522 form a docking through hole 525. The shape of the through hole matches the outer contour of the center contact member, so as to provide radial constraint and positioning for the center contact member when the left clamping block 5113 and the right clamping block 5114 are clamped, and to provide primary guidance for the docking needle 493 before it enters the insertion hole of the center contact member, thereby stabilizing the spatial position of the insertion hole on the center contact member. The end of the docking through hole 525 near the main body picking claw has an outwardly expanding tapered opening, which communicates with the docking through hole 525, thereby reducing the positional accuracy of the docking needle 493, and thus ensuring that the docking needle 493 can be inserted into the insertion hole of the center contact member along the outwardly expanding tapered opening.

[0086] refer to Figure 23 The control system (such as a PLC control system) controls the auxiliary drive 491 so that after the docking needle 493 is guided into the insertion hole of the center contact, it performs a synchronous retraction action that is coordinated with the movement of the main body's pick-up claw toward the riveting position. The retraction speed is related to the movement speed to avoid rigid interference when the main body reaches the riveting position.

[0087] refer to Figures 18-26 The cooperation process between the main body gripper and the auxiliary guide assembly is as follows: When the main body gripper picks up the main body from the material strip, the auxiliary drive component 491 is activated, causing the mating needle 493 to insert into the coaxial hole of the main body from the non-riveted end. Subsequently, the main body cutting device 48 separates the main body from the material strip; Then the main body picking claw moves the main body towards the center contact and prepares to dock with the center contact on the wire. First, the docking pin 493 is inserted into the insertion hole of the center contact to precisely guide the docking pin 493 to be axially aligned with the center contact. As the main body's gripper continues to move the main body closer to the center contact, the distance between the main body and the center contact becomes increasingly shorter. To prevent the mating pin 493 from excessively inserting into the center contact due to the gripper's movement and potential damage or interference, the auxiliary drive unit 491 controls the mating pin 493 to gradually retract relative to the second lower clamping block 4732. This process ensures alignment accuracy while eliminating the risk of rigid interference until the main body reaches the preset riveting position. This ensures the stability of the relative position between the center contact and the main body during movement and avoids positional interference caused by the mating pin 493, ensuring that the mating pin 493 can completely retract when the main body finally reaches its final position, without interfering with the final pressing of the center contact and the main body.

[0088] This enables the assembly of tiny parts such as the main body and the center contact component. After the main body moves to the riveting position, the second riveting drive 458 moves the second riveting wedge 457 closer to the second riveting slider 454, pushing the second riveting slider 454 upward and causing the second riveting lower blade 456 to reach the riveting position. At this time, the second lower jaw supports and positions the lower side of the main body. Then, the main body press 451 moves to make the second riveting upper blade 455 rush towards the second riveting lower blade 456, thereby riveting the main body onto the outer sheath of the wire and the braided shielding layer of the flange. Then, the main body press 451 returns to its original position with the second riveting upper blade 455, thus completing the riveting of the main body and the wire. At this point, the female connector has completed the assembly with the wire to form a coaxial cable product.
