Description

Technical Field

[0001] This utility model relates to the field of wire harness connector assembly technology, and in particular to a wire harness connector assembly device. Background Technology

[0002] Wire harness connectors are key electronic components used to achieve electrical connections and mechanical fixation between wire harnesses and electrical equipment and components. They are used in the automotive and industrial control fields. Their core function is to integrate multiple wires into a wire harness and then quickly connect it to other devices through standardized interfaces to form a complete circuit system, while ensuring the conductivity, reliability and environmental adaptability of the connection.

[0003] Wire harness connector assembly equipment is a specialized mechanical device used to automate or semi-automatically assemble wire harnesses and connectors. It is mainly used in electronics, automobiles, or other fields that require wire harness connections. Its core function is to precisely combine wire harnesses and connectors through crimping, soldering, and insertion / removal processes to form reliable electrical connection components, replacing traditional manual operations and improving production efficiency and product consistency.

[0004] Early wire harness connector assembly equipment mainly consisted of a terminal crimping module and an insertion mechanism. The crimping module connected the terminals to the wire harness, while the insertion mechanism completed the precise insertion of the connector. Due to the low positioning accuracy and poor compatibility of early equipment, wire harness bending could cause jamming, resulting in unstable wire harness placement. To solve this problem, existing equipment uses fixing blocks to fix the terminals and anti-misalignment grooves to limit the placement direction of the terminals, ensuring the assembly accuracy of the wire harness. However, in actual use, because the fixing blocks are rigidly fixed, they cannot adapt to different types and thicknesses of wire harnesses to complete the assembly, thus failing to meet the needs of users.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 3 and Figure 6 The present invention provides an embodiment of a wire harness connector assembly device, comprising a body 1, a cavity 2 provided inside the body 1 for providing installation space, a clamping mechanism 3 provided on the rear side of the inner wall of the cavity 2, and an alarm mechanism 4 provided on the front side of the inner wall of the cavity 2.

[0035] The clamping mechanism 3 includes a pressure sensor 301, which senses the compressive force exerted on the terminals during assembly. The rear side of the pressure sensor 301 is fixedly connected to the rear side of the inner wall of the cavity 2. A cylinder 302 is fixedly connected to the front side of the pressure sensor 301. The cylinder 302 reduces the compressive force exerted on the terminals by contracting. A connecting plate 303 is fixedly connected to the output end of the cylinder 302. A rotating cylinder 304 is rotatably connected to the middle of the front side of the connecting plate 303. The connecting plate 303 is connected to the turntable 305 through the rotating cylinder 304. The rotating cylinder 304 serves as a connection and support mechanism. A turntable 305 is fixedly connected to the front end of the device. Multiple guide grooves 306 are provided on the front side of the turntable 305. The rotation of the turntable 305 causes the guide grooves 306 to exert a guiding effect on the clamping rods 307. The inner walls of the multiple guide grooves 306 are slidably connected to the clamping rods 307. The clamping rods 307 are used to clamp the wire harness. Multiple connecting rods 308 are rotatably connected to the front end of the connecting plate 303. The rear ends of the multiple clamping rods 307 are rotatably connected to one end of the corresponding connecting rods 308. A drive assembly 309 is provided on the rear right end of the connecting plate 303. A directional assembly 310 is provided on the front side of the turntable 305.

[0036] The drive assembly 309 includes a servo motor 3091. The front end of the servo motor 3091 is fixedly connected to the rear right end of the connecting plate 303. The output end of the servo motor 3091 passes through the rear side of the connecting plate 303 and is fixedly connected to a gear 3092. A gear ring 3093 is fixedly connected to the outer wall of the turntable 305. The gear 3092 and the gear ring 3093 are meshed together. The servo motor 3091 drives the gear ring 3093 to rotate through the gear 3092, thereby causing the turntable 305 to rotate.

[0037] The orientation assembly 310 includes a fixed shaft 3101, the rear end of which is fixedly connected to the front center of the connecting plate 303. A rotating hole 3102 is provided in the front center of the turntable 305. When the turntable 305 rotates, the fixed shaft 3101 is fixed in the rotating hole 3102. The front side of the outer wall of the fixed shaft 3101 is rotatably connected to the inner wall of the rotating hole 3102. A slot 3103 is provided at the front end of the fixed shaft 3101. An orientation block 3104 is slidably connected inside the slot 3103. The orientation block 3104 provides orientation for the wire harness terminals through the slot at the front end. The orientation block 3104 can be pulled out of the slot 3103 for easy replacement.

[0038] Specifically, the device positions the wire harness by inserting the wire harness terminals into the orientation block 3104. During wire harness assembly, pressure sensor 301 controls the operation of cylinder 302. Once the pressure during assembly exceeds a preset value, cylinder 302 drives connecting plate 303 to retract, thereby reducing the pressure. Before assembly, servo motor 3091 starts, and its output drives gear 3092 to rotate. The meshing of gear 3092 and gear ring 3093 causes turntable 305 to rotate. Turntable 305 is connected to connecting plate 303 via rotating cylinder 304. Connected to 03, the rotating drum 304 provides the necessary support. When the turntable 305 rotates, the guide groove 306 applies a guiding force to the clamping rod 307. The clamping rod 307 is connected to the connecting plate 303 through the connecting rod 308. The rotating rod applies a certain limiting force to the clamping rod 307. Multiple clamping rods 307 converge towards the center under the action of the guiding force, thereby being able to clamp wire harnesses of different thicknesses. At the same time, the rear side of the directional block 3104 cooperates with the slot 3103 at the front end of the fixed shaft 3101. By replacing different directional blocks 3104, terminals with different end faces can be adapted, improving the practicality of the equipment.

[0039] Reference Figure 1 , Figure 4 and Figure 5 The alarm mechanism 4 includes a second servo motor 401. The left end of the second servo motor 401 is fixedly connected to the front left side of the inner wall of the cavity 2. A bidirectional threaded rod 402 is fixedly connected to the output end of the second servo motor 401. The second servo motor 401 can drive the bidirectional threaded rod 402 to rotate. Moving blocks 403 are threadedly connected to the left and right sides of the outer wall of the bidirectional threaded rod 402. The rotation of the bidirectional threaded rod 402 causes the moving blocks 403 on both sides to move in opposite directions. A clamping block 404 is fixedly connected to the top of each of the two moving blocks 403. The clamping blocks 404 are close to each other to clamp the wire harness. A sliding groove 405 is opened at the rear end of each adjacent side of the two clamping blocks 404. Pressure alarms 406 are slidably connected to adjacent sides of the inner wall of the slide 405. The pressure alarms 406 sense the pressure through the contact wire harness to prevent the clamping block 404 from applying too much or too little pressure. Springs 407 are fixedly connected to the opposite sides of the two pressure alarms 406. The springs 407 can reset the pressure alarms 406. The opposite sides of the two springs 407 are respectively fixedly connected to one side of the inner wall of the corresponding slide 405. A limit groove 15 is opened on the front side of the inner wall of the machine body 1. The front sides of the two moving blocks 403 are slidably connected to the inner wall of the corresponding limit groove 15. The limit groove 15 plays a role in limiting and guiding the moving blocks 403.

[0040] Specifically, during assembly, servo motor 401 is started, and its output drives bidirectional threaded rod 402 to rotate. This causes two moving blocks 403 to move towards the center along the bidirectional threaded rod 402 via threaded connection. The moving blocks 403 then drive the clamping block 404 to move, thereby clamping and fixing the wire harness. Pressure alarm 406 contacts the wire harness. As servo motor 401 continues to operate, the clamping force gradually increases. When pressure alarm 406 senses increased pressure, it slides into the slide groove 405, causing spring 407 to be compressed. At this time, pressure alarm 406 issues an alarm signal, causing servo motor 401 to stop working. This is to avoid excessive clamping force that could damage the insulation layer of the wire harness, or insufficient clamping force that could cause the wire to slip during processing, resulting in dimensional errors. After the wire harness is assembled and removed, spring 407 will reset pressure alarm 406.

[0041] Reference Figure 1 , Figure 2 and Figure 3 The bottom left and right sides of cavity 2 are fixedly connected to slide rails 16. The top of the two slide rails 16 are slidably connected to the same movable shell 5. The movable shell 5 can move back and forth through the slide rails 16. The rear top of the movable block 403 has a groove 6. The upper part of the inner wall of the groove 6 is slidably connected to a placement block 7. The top of the placement block 7 has a directional groove 8. The placement block 7 limits the direction of the assembled parts through the directional groove 8. The lower part of the rear side of the outer wall of the movable shell 5 is fixedly connected to a cylinder 9. The output end of the cylinder 9 is fixedly connected to the bottom of the placement block 7. The cylinder 9 can make the placement block 7 move up and down along the groove 6. The sliding and movable shell 5 has slide rails 10 fixedly connected to the left and right ends of the rear side of the outer wall. Slider 11 is slidably connected to the upper middle part of the rear side of the two slide rails 10. The left and right sides of the placement block 7 are fixedly connected to the corresponding slider 11. The slide rails 10 and slider 11 play an auxiliary role in the up and down movement of the placement block 7. The top left front end of the body 1 has slide rail 12 fixedly connected to the top. Slider 13 is slidably connected to the top left side of slide rail 12. Slider 13 can move along slide rail 12. Protective cover 14 is fixedly connected to the left side of slider 13. When slide rail 12 moves, it drives protective cover 14 to move together.

[0042] Specifically, the assembly components inside the placement block 7 can be assembled by sliding the movable shell 5 on the slide rail 16. The assembly components are installed in the orientation groove 8 to avoid incorrect installation. After the components above the placement block 7 are assembled, the cylinder 2 9 is activated to move the placement block 7 down along the groove 6. Then the movable shell 5 continues to slide backward, so that the components on the front side of the movable shell 5 can continue to complete the assembly process. During the assembly process, the protective cover 14 is pulled to move along the slide rail 3 12 via the slider 3 13 to cover the components and prevent accidents.

[0043] Working principle: This device limits the direction of the wire harness by inserting the wire harness terminals into the directional block 3104. During wire harness assembly, the pressure sensor 301 controls the operation of cylinder 302. When the assembly pressure is too high, cylinder 302 drives the connecting plate 303 to contract, relatively reducing the pressure. Then, servo motor 3091 is started, and the output of servo motor 3091 drives gear 3092 to rotate. Through the meshing of gear 3092 and gear ring 3093, turntable 305 rotates. Turntable 305 is connected to connecting plate 3093 via rotating cylinder 304. 3. The rotating drum 304 provides support. After the turntable 305 rotates, the guide groove 306 applies a guiding force to the clamping rod 307. The clamping rod 307 is connected to the connecting plate 303 through the connecting rod 308. The rotating rod limits the clamping rod 307 to a certain extent. Multiple clamping rods 307 converge towards the center through the guiding force, which can clamp wire bundles of different thicknesses. At the same time, the rear side of the directional block 3104 engages with the slot 3103 at the front end of the fixed shaft 3101. By pulling out and replacing different directional blocks 3104, it can be adapted to terminals with different end faces, which improves the practicality of the device.

[0044] During assembly, servo motor 401 is started, and its output drives bidirectional threaded rod 402 to rotate. This causes two moving blocks 403 to move towards the center along the bidirectional threaded rod 402 via threaded connection. The moving blocks 403 drive clamping block 404 to move, clamping and fixing the wire harness. At the same time, pressure alarm 406 contacts the wire harness during clamping. As servo motor 401 continues to run, the clamping force gradually increases. At this time, pressure alarm 406 slides into the slide groove 405, and spring 407 is compressed. Simultaneously, pressure alarm 406 sounds an alarm, stopping servo motor 401 to prevent excessive clamping force from crushing the insulation layer of the thin wire harness. It also prevents insufficient clamping force from causing the wire to slip during processing, resulting in dimensional deviations. After the wire harness is assembled and removed, spring 407 resets pressure alarm 406.
