Description

Technical Field

[0001] This application relates to the field of automation equipment technology, and in particular to a flexible feeding connector assembly and forming inspection integrated machine. Background Technology

[0002] As electronic devices become increasingly miniaturized and precise, the demand for connectors, as fundamental components for electrical connections in electronic devices, continues to grow, while the requirements for product quality and production efficiency are also constantly increasing. Connector production typically involves multiple stages, including wire end processing, terminal crimping, insulation protection, terminal insertion into the plastic housing, and finished product inspection. Each stage has strict requirements regarding the sequence and positional accuracy.

[0003] In existing connector manufacturing methods, the aforementioned stages are often completed by different equipment, requiring manual or auxiliary equipment for material transfer between these machines. This decentralized production method presents the following problems: Firstly, the transfer of semi-finished products between different machines requires multiple clamping and positioning operations, resulting in significant cumulative positioning errors that affect the crimping quality of terminals and wires, as well as the positional accuracy of terminals inserted into the plastic housing. Secondly, manual transfer and loading / unloading consume considerable production time, leading to long waiting times between equipment, a slow overall production cycle, and the potential for defects such as wire bending and terminal deformation due to manual operation. Furthermore, the separate operation of each machine with its own operators and testing methods results in high labor costs, and product quality is heavily influenced by the operator's skill level, making it difficult to guarantee consistency between different batches. Summary of the Invention

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. Rather, embodiments of this application include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0021] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 14As shown in the figure, this embodiment discloses a flexible feeding connector assembly, forming and testing integrated machine, including a frame 1, a cover 3 on the frame 1, the cover 3 covers each working mechanism inside, a human-machine interface 2 is provided on one side of the cover 3, and a feeding port corresponding to the hot melt tube feeding rack 9 and the hinge needle hopper 27 is provided on the cover 3 to facilitate the replenishment of materials.

[0023] The frame 1 is equipped with a wire crimping system and a heat shrink tubing assembly system. The wire crimping system is used to complete wire feeding, stripping, wire feeding, wire crimping, crimping, inspection, and cutting. The heat shrink tubing assembly system is used to complete heat shrink tubing feeding, cutting, tubing insertion, heat shrinking, wire end cold stripping, laser marking, wire crimping, and the insertion, crimping, and assembly and inspection of plastic parts.

[0024] I. Crimping system for retractable wires.

[0025] like Figures 1 to 4 As shown, the crimping system includes an indexing mechanism 29, which comprises a divider and a turntable 31 connected to the output end of the divider. Multiple carriers 37 are arranged circumferentially on the turntable 31. Each carrier 37 includes a carrier body and a wire positioning groove formed on the carrier body. The wire is positioned within the wire positioning groove and rotates with the turntable 31. The circumference of the turntable 31 is provided with a wire feeding and shifting mechanism 24, a laser wire stripping mechanism 23, a wire sheathing mechanism 28, a crimping mechanism 33, a crimping mechanism 5, a wire detection structure 6, and a wire cutting mechanism 22. In this embodiment, the above mechanisms are arranged sequentially along the rotation direction of the turntable 31, each corresponding to a carrier 37 on the turntable 31, and the carriers 37 are evenly distributed circumferentially.

[0026] The wire feeding and shifting mechanism 24 is equipped with a wire reel 30 and a wire pulling mechanism 4 on its outer side. The wire pulling mechanism 4 includes a wire pulling gripper and a wire pulling translation module. The wire pulling gripper is located above the wire guide rail, with one end of the wire guide rail facing the wire reel 30 and the other end facing the carrier 37. During operation, the wire pulling gripper of the wire pulling mechanism 4 clamps the wire end on the wire reel 30, and the wire pulling translation module drives the wire pulling gripper to move to pull the wire out to a set length. The wire is then transported to the wire feeding and shifting mechanism 24 via the wire guide rail.

[0027] like Figure 5As shown, the wire feeding and shifting mechanism 24 and the wire sheath pulling mechanism 28 constitute the wire stripping and feeding module. The wire stripping and feeding module includes a module mounting plate, a wire feeding wheel assembly, a wire clamping claw, and a translation drive component. The wire feeding wheel assembly and the wire clamping claw are both mounted on the module mounting plate. The wire feeding wheel assembly is located on the upper part of the module mounting plate, and the wire clamping claw is located below the wire feeding wheel assembly and facing the carrier 37. The wire feeding wheel assembly includes a driving wheel and a driven wheel arranged opposite each other. The wire passes between the driving wheel and the driven wheel. The rotation of the driving wheel transports the wire to the wire positioning groove on the carrier 37. The laser stripping mechanism 23 is located on one side of the wire stripping and feeding module and includes a stripping laser head and a stripping positioning seat. The stripping laser head is located above the stripping positioning seat. After the wire rotates with the turntable 31 to the laser stripping station, the stripping laser head emits a laser to circumferentially cut the insulation layer at the end of the wire, separating the insulation layer from the wire core. After circumferential cutting, the clamping claws hold the circumferentially cut insulation at the end of the conductor, and the translational drive drives the clamping claws to move in a direction parallel to the conductor axis, pulling the insulation off the conductor core.

[0028] like Figure 6 As shown, a pin loading system 34 is provided on one side of the pin loading mechanism 33. The pin loading system 34 includes a pin hopper 27, a pin flexible disk 26, a second flexible disk industrial camera 25, and a first robot 17. The pin hopper 27 is located on one side of the pin flexible disk 26, and its discharge end is connected to the disk surface of the pin flexible disk 26. Pins are stored in the pin hopper 27 and transported to the pin flexible disk 26 from the discharge end. The pin flexible disk 26 disperses the pins on its disk surface through vibration. The second flexible disk industrial camera 25 is located directly above the pin flexible disk 26, with its lens facing the disk surface of the pin flexible disk 26, for photographing the pins on the disk surface and identifying the position and orientation of the pins. The first robot 17 is located between the pin flexible disk 26 and the pin loading mechanism 33, and includes a base fixed to the frame 1, a multi-axis robotic arm connected to the base, and a gripper located at the end of the robotic arm. The first robot 17 is connected to the second flexible disk industrial camera 25 by signal, and is configured to pick up the reamer from the reamer flexible disk 26 and place it on the reamer material position 333 according to the reamer position information collected by the second flexible disk industrial camera 25.

[0029] like Figure 7 As shown, the pin mounting mechanism 33 includes a clamping mechanism 331, a pushing mechanism 332, and a pin loading position 333. The clamping mechanism 331 and the pushing mechanism 332 are located on both sides of the carrier 37 and are arranged opposite to each other. The pin loading position 333 is located between the clamping mechanism 331 and the pushing mechanism 332. The pushing mechanism 332 includes a pushing rod and a pushing drive. The pushing rod is coaxially arranged with the pin loading position 333 and faces the end of the wire on the carrier 37. After the pin is placed in the pin loading position 333, the clamping mechanism 331 clamps the end of the wire on the carrier 37, and the pushing drive drives the pushing rod to push the pin onto the wire core.

[0030] like Figure 3 and Figure 8 As shown, the crimping mechanism 5 includes a crimping seat and a crimping connector. The crimping seat is located below the carrier 37, and the crimping connector is located directly above the crimping seat and connected to the crimping drive component. The crimping connector can move up and down relative to the crimping seat. After the reamer pin is fitted onto the end of the wire, the wire rotates with the turntable 31 to the crimping position, and the crimping connector descends to crimp and fix the reamer pin to the wire. The reamer pin wire crimping system also includes a crimping mechanism 32, which is located between the crimping mechanism 5 and the wire detection structure 6. It is used to perform secondary crimping or shaping on the crimped reamer pin to ensure crimping quality.

[0031] like Figure 9 As shown, the wire inspection structure 6 includes a wire inspection camera 61 and a wire inspection position 62. The wire inspection camera 61 is located above the wire inspection position 62, with its lens facing the wire inspection position 62. After crimping, the wire rotates with the turntable 31 to the inspection station. The wire inspection camera 61 performs visual inspection on the crimping quality of the wire ends to determine whether the crimping pin is in place and whether there are any defects such as loose strands in the wire core.

[0032] The wire cutting mechanism 22 is located downstream of the wire detection structure 6 and includes a fixed cutter and a movable cutter, with the movable cutter connected to the cutting drive. After detection, the wire rotates with the turntable 31 to the cutting station, and the movable cutter moves toward the fixed cutter to cut the wire into wire-tipped needles of a set length.

[0033] II. Heat shrink tubing assembly system.

[0034] like Figure 10 and Figure 12 As shown, the heat shrink tubing assembly system includes a heat melt tubing feeder 9, a heat shrink tubing feeding mechanism 19, a heat shrink tubing cutting and misalignment mechanism 20, a heat shrink tubing threading mechanism 18, and a heating mechanism 21. The heat melt tubing feeder 9 holds rolls of heat shrink tubing. The heat shrink tubing feeding mechanism 19 includes a feeding wheel assembly and a feeding drive. The feeding wheel assembly includes a driving wheel and a driven wheel arranged opposite each other. The driving wheel is connected to the feeding drive, and the heat shrink tubing passes between the driving wheel and the driven wheel. The feeding drive drives the driving wheel to rotate to transport the heat shrink tubing.

[0035] The heat shrink tubing cutting and misalignment mechanism 20 includes a cutter and a misalignment translation stage. The cutter is located at the discharge end of the feeding wheel assembly, and the misalignment translation stage is located below the cutter. After the heat shrink tubing is fed out to a set length, the cutter cuts the heat shrink tubing, and the cut heat shrink tubing falls onto the misalignment translation stage. The misalignment translation stage then moves the heat shrink tubing to the tubing insertion station.

[0036] like Figure 13As shown, the heat shrink tubing threading mechanism 18 includes a threading guide seat and a threading push rod. The threading guide seat is located between the heat shrink tubing cutting and misalignment mechanism 20 and the heating mechanism 21. The threading guide seat has a guide hole for the heat shrink tubing to pass through. The threading push rod is coaxially arranged with the guide hole and connected to the threading drive component. After the wire-carrying needle is transported to the threading station by the wire-carrying needle transport mechanism 10, the threading drive component drives the threading push rod to move axially along the guide hole, pushing the heat shrink tubing out of the guide hole and threading it through to the connection point between the needle and the wire at the end of the wire.

[0037] like Figure 14 As shown, the heating mechanism 21 includes a clamping cylinder 211 and a heating block 212. The two piston rod ends of the clamping cylinder 211 are respectively connected to clamping blocks. The two clamping blocks are arranged opposite each other, forming a clamping position for the heat shrink tubing to pass through. The heating block 212 is attached to the outside of the clamping blocks or embedded within them. The clamping position is aligned with the discharge end of the heat shrink tubing insertion mechanism 18. After the heat shrink tubing is inserted, the clamping cylinder 211 drives the two clamping blocks to close and clamp the wire. The heating block 212 heats the heat shrink tubing, causing it to shrink and tightly hug the connection between the wire and the reamer.

[0038] The wire end cold stripping mechanism 7 is located downstream of the heating mechanism 21 and includes a cold stripping blade and a cold stripping translation drive. The cold stripping blade is arranged toward the wire conveying path and is used to perform cold stripping on the other end of the wire to remove the insulation layer at that end.

[0039] Laser machine 8 is a laser marking machine located downstream of wire tail cold stripping mechanism 7. It includes a marking column and a marking laser head located at the top of the marking column, above the wire conveying path. After the wire tail is cold stripped, the marking laser head laser-marks the surface of the wire to engrave product identification information.

[0040] like Figure 11 As shown, the wire-embedded needle insertion mechanism 36 includes a gripper 361, a transport guide rail 362, a cutting blade 363, a needle insertion drive, and a needle positioning seat. The gripper 361 is slidably connected to the transport guide rail 362 via a slider. One end of the transport guide rail 362 faces the wire-embedded needle transport mechanism 10 to form a material picking position, and the other end faces the plastic carrier loading mechanism 16 to form a needle insertion position. The needle positioning seat is located at the needle insertion position, and the cutting blade 363 is located between the material picking position and the needle insertion position, with its blade facing the movement path of the gripper 361. After the gripper 361 clamps the wire-embedded needle at the material picking position, it moves along the transport guide rail 362. During the movement, the cutting blade 363 trims and shapes the end of the wire. After the gripper 361 reaches the needle insertion position, the needle insertion drive drives the gripper 361 to move in a direction perpendicular to the transport guide rail 362, inserting the wire-embedded needle into the plastic part hole on the needle positioning seat.

[0041] The wire-embedded pin pressing mechanism 12 is located above the plastic carrier loading mechanism 16. It includes a pressing head and a pressing drive. The pressing head is located above the plastic carrier loading mechanism 16, and the pressing drive is connected to the pressing head and drives the pressing head to move up and down vertically. After the wire-embedded pin is inserted into the plastic part, the pressing head descends to press the pin into the set depth.

[0042] The plastic hole position detection mechanism 11 is located next to the wire-connected pin pressing mechanism 12. It includes a hole position detection camera and a detection light source. The hole position detection camera is located above the plastic carrier loading mechanism 16, with the lens facing the carrier. It is used to detect whether the hole position of the plastic part is qualified and whether the pin is pressed into place.

[0043] The plastic carrier loading mechanism 16 includes a carrier conveyor belt and a positioning block. The positioning block is located below the wire needle pressing mechanism 12. After the carrier conveyor belt transports the plastic part carrier to the pressing station, it is positioned by the positioning block.

[0044] The heat shrink tubing assembly system also includes a first hopper 13, a first flexible disk industrial camera 14, a flexible disk 15, and a plastic handling robot 35. The first hopper 13 is located on one side of the flexible disk 15, with its discharge end connected to the disk surface of the flexible disk 15. Plastic parts are transported from the first hopper 13 onto the flexible disk 15, where vibration causes the plastic parts to disperse and arrange themselves. The first flexible disk industrial camera 14 is located above the flexible disk 15, with its lens facing the disk surface, used to identify the position and orientation of the plastic parts. The plastic handling robot 35 is located between the flexible disk 15 and the plastic carrier loading mechanism 16, and includes a base fixed to the frame 1, a multi-axis robotic arm connected to the base, and a suction cup or gripper at the end of the robotic arm. The plastic handling robot 35 is signal-connected to the first flexible disk industrial camera 14 and configured to pick up plastic parts from the flexible disk 15 and place them into the carrier of the plastic carrier loading mechanism 16 based on the position information of the plastic parts acquired by the first flexible disk industrial camera 14.

[0045] The wire-embedded pin transport mechanism 10 is a beam-type linear transport module, including a beam, a slider, and a transport drive component. The beam is mounted between the pin crimping system and the heat shrink tubing assembly system. One end of the beam is located above the wire cutting mechanism 22, and the other end extends above the heat shrink tubing insertion mechanism 18. The slider is slidably connected to the beam. The transport drive component drives the slider to move along the beam. The slider is equipped with gripping fingers that grip the wire-embedded pin and move it along the beam, transporting the wire-embedded pin from the wire crimping system to various stations in the heat shrink tubing assembly system.
