Description

Technical Field

[0001] This utility model relates to the field of insulation displacement technology, and in particular to a device for automatically performing double-ended non-contact, weldless insulation displacement connection. Background Technology

[0002] Non-contact solderless insulated displacement connectors belong to a type of insulated displacement technology. They use specially designed metal contacts to cut into the outer insulation of the insulated wire during the crimping process, directly forming a tight mechanical and electrical connection with the internal conductor.

[0003] However, existing equipment is mostly semi-automated, requiring manual operation for loading, positioning, clamping, and crimping of cables and connectors. This results in low automation, difficulty in improving production efficiency, and heavy reliance on operator experience and skill, leading to poor product consistency. More significantly, traditional equipment commonly uses single-end crimping, meaning only one end of the wire harness can be connected at a time, requiring re-clamping and secondary processing of the other end. This is not only cumbersome and time-consuming, but also prone to introducing reference deviations during the two clamping processes, making it difficult to maintain high consistency in key parameters such as position, height, and angle of the two-end connectors. Therefore, existing non-contact, solderless, insulated displacement connection technology faces prominent problems when applied to the high-precision, high-efficiency manufacturing of new energy vehicle wire harnesses, including low automation, poor processing efficiency, difficulty in ensuring consistency between the two ends, and insufficient positioning accuracy.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] like Figures 1 to 5As shown, an automatic double-ended non-contact, solderless, insulated displacement connection device is used to achieve automated solderless crimping connection at both ends of a wire harness. The device includes a body 1, a feeding mechanism 2, a detection mechanism 3, a positioning mechanism 4, and a connecting mechanism 5.

[0021] The body 1 provides support for the overall structure and integrates a power supply system to power the various functional components.

[0022] The feeding mechanism 2 is mounted on the machine body 1 and is used to carry and transport the wire harness to be processed. The feeding mechanism 2 includes a rotatable indexing plate 205, on which multiple feeding fixtures are evenly arranged circumferentially. Each feeding fixture is used to fix one wire harness to be processed. The indexing plate 205 rotates intermittently under the drive of the drive device, so that each feeding fixture stops at a different station in sequence, realizing continuous feeding and process flow.

[0023] The detection mechanism 3 is located on either side of the feeding mechanism 2 and is used to automatically detect the assembly status of the wire harness to be processed on the feeding fixture.

[0024] The positioning mechanism 4 includes positioning clamping components 403 symmetrically arranged on both sides of the feeding mechanism 2. The two positioning clamping components 403 can slide back and forth in a direction parallel to the upper surface of the machine body. They are used to clamp and fix the double-ended connectors of the wire harness to be processed when the control system confirms that the assembly status is qualified. The control system, upon receiving an assembly status qualified signal from the detection mechanism 3, drives the positioning mechanism 4 and the connecting mechanism 5 to perform subsequent clamping and crimping operations; if an assembly status unqualified signal is received, it controls the indexing plate to stop rotating or issues an alarm.

[0025] The connecting mechanism 5 is disposed between two positioning and clamping assemblies 403. The connecting mechanism 5 includes a crimping assembly 503, which can move up and down in a direction perpendicular to the upper surface of the machine body. The crimping assembly 503 is located above the feeding fixture, and its working area corresponds to the position of the workpiece to be processed in the feeding fixture. After the wire harness is clamped and fixed, the crimping assembly 503 moves downward, simultaneously performing a non-contact, solderless, insulated displacement connection operation on both ends of the wire harness to be processed, completing the simultaneous crimping of both ends.

[0026] Furthermore, the indexing plate 205 is a circular turntable structure, divided into four workstations along two mutually perpendicular diameters: a loading workstation 201, an inspection workstation 202, a processing workstation 203, and a preparation workstation 204. The four workstations are sequentially adjacent along the circumference of the indexing plate 205 and are centrally symmetrically distributed with the center of the indexing plate as the center of symmetry. This ensures precise workstation switching every time the indexing plate 205 rotates 90°, meeting the needs of simultaneous multi-station operation and sequential processing. The centrally symmetrical distribution of the four workstations ensures balanced force distribution at each workstation, stable operation, effectively reducing equipment vibration and wear, and improving the stability and lifespan of the equipment.

[0027] A feeding fixture is installed at the workstation for placing and conveying the parts to be processed. The feeding fixture has a boss structure that is high in the middle and low on both sides. The lower platform surfaces on both sides are provided with ports that match the shape of the double-ended connectors for placing the double-ended connectors of the wire harness to be processed. This structure provides stable support for the subsequent pressing action of the crimping assembly, significantly improving the stability of the crimping process and the consistency of the connection quality.

[0028] Furthermore, such as Figure 2 As shown, the detection mechanism 3 is located on the upper surface of the machine body, next to the detection station 202. When the indexing plate rotates 90 degrees, the feeding fixture installed on the loading station 201, together with the wire harness to be processed, is precisely transferred into the detection station 202, and the detection mechanism 3 then performs non-contact detection on the assembly status of the wire harness.

[0029] The detection mechanism 3 includes four photoelectric sensors 301 and a support 302 for fixing. The support 302 is fixed to the machine body, and the four photoelectric sensors 301 are symmetrically arranged above the four corner areas of the feeding fixture via the support 302, forming a rectangular distribution. The detection end of each photoelectric sensor 301 faces the two port areas on the feeding fixture, and is used to monitor whether the double-ended connector is properly assembled.

[0030] Because the four photoelectric sensors are symmetrically arranged, the assembly status of the double-ended connector can be detected simultaneously, realizing full-circumference, multi-point integrity detection and significantly improving the reliability of the detection.

[0031] Furthermore, such as Figures 3 to 4 As shown, the positioning mechanism 4 is symmetrically arranged on both sides of the detection station 203 of the indexing plate 205. It is used to clamp and position the wire harness to be processed that has been fed into place before crimping, so as to ensure that the cable position is stable and the centering is accurate during the subsequent insulation displacement connection process, and to avoid connection failure caused by offset or misalignment.

[0032] The positioning mechanism 4 includes two side-pressure servo motors 401, two transverse guide rails, and two symmetrically arranged positioning clamping assemblies 403. The two side-pressure servo motors 401 are symmetrically installed at both ends of the detection station 203, with a certain distance between them, to provide a power source for synchronous positioning on both sides.

[0033] Each side pressure servo motor 401 has a horizontal guide rail fixedly mounted on one side, serving as a guide support structure for the positioning and clamping assembly 403. The two positioning and clamping assemblies 403 are respectively mounted on the corresponding horizontal guide rails via a horizontal slide 402, and can move synchronously inward or outward in the horizontal direction (i.e., radial direction) under the drive of the servo motor, thereby achieving the clamping and release of the double-ended connector.

[0034] The positioning and clamping assembly 403 includes a base 404, a fixed cover plate 405, a positioning plate 409, and a positioning extension arm 407. The base 404 is fixed to the transverse slide 402 and is perpendicular to the surface of the transverse slide 402, forming the main support structure of the entire clamping assembly. The fixed cover plate 405 is fixedly connected to the base 404 and extends perpendicular to the surface of the base, used for mounting and limiting internal moving parts.

[0035] The positioning plate 409 is located below the fixed cover plate 405 and is connected to the base 404 via an elastic connecting mechanism 410. It also forms a slidable guiding engagement with the fixed cover plate 405 via a slide rail 406 and a slider 408. This design allows the positioning plate 409 to have a certain floating compensation capability when subjected to external forces, automatically adapting to minor assembly errors during clamping and preventing rigid collisions from damaging cables or fixtures.

[0036] The positioning plate 409 extends along a direction parallel to the upper surface of the machine body, with positioning extension arms 407 extending from the end of each arm. The end of each arm points towards the port of the feeding fixture in the detection station 203 and is at the same horizontal plane as the port. When the servo motor drives the positioning clamping assembly 403 to close towards the center, the positioning extension arms 407 on both sides simultaneously contact the connectors at both ends of the wire harness to be processed, limiting and laterally clamping the connectors to ensure that the wire harness remains centered during the crimping process and prevents displacement.

[0037] Furthermore, such as Figure 3 and Figure 5 As shown, the connecting mechanism 5 is located above the detection station 203 of the indexing plate 205 and is used to perform a double-end non-contact, solderless, insulated displacement connection operation on the double-end fixed wire harness to be processed.

[0038] The connecting mechanism 5 includes a pressing servo motor 501, a vertical guide rail, and a pressing assembly 503. The pressing servo motor 501 is mounted at the center of the lateral spacing area of ​​the positioning mechanism 4, with its output shaft perpendicular to the upper surface of the body 1, providing controllable power input for the pressing action. Vertical guide rails are symmetrically arranged on the surface of the pressing servo motor 501 to guide the up-and-down movement of the pressing assembly, ensuring straightness and parallelism during the pressing process. The pressing assembly is slidably connected to the vertical guide rail via a lifting slide 502, allowing it to smoothly rise and fall along the vertical guide rail under the drive of the pressing servo motor 501, achieving precise guidance and low-friction operation for the pressing action.

[0039] The pressing assembly 503 includes a baffle 504, a pressure plate 505, a buffer plate 506, a pressure head 508, and a gantry bracket 507. The pressure plate 505, buffer plate 506, and pressure head 508 are connected sequentially from top to bottom. The baffle 504 is vertically mounted on the pressure plate 505. The surface of the lifting slide 503 has a fitting groove, and the pressure plate 505 is embedded and fixedly connected within this groove, forming a rigid transmission structure that effectively transmits the downward pressure from the servo motor.

[0040] The pressure plate 505 is connected to the buffer plate 506 through the buffer structure 510. The buffer structure 510 is an elastic compression spring, which is used to absorb the impact energy at the moment of crimping, prevent overpressure damage to the wire harness to be processed, and achieve uniform pressure application to improve the consistency of crimping quality.

[0041] The buffer plate 506 and the pressure head 508 are connected by screws and bolts, which facilitates the replacement of the appropriate pressure head mold according to different wire harness specifications to be processed. The pressure head 508 has grooves on both sides and is aligned with the feeding fixture located on the inspection station 203 in the vertical projection direction to ensure accurate pressing position.

[0042] The gantry frame 507 includes a crossbeam and two vertical columns. The crossbeam is fixed to the bottom surface of the buffer plate 506, and the two vertical columns extend downward and pass through the grooves on both sides of the pressure head 508, respectively, and are at the same horizontal plane as the bottom surface of the pressure head 508. This gantry structure presses down synchronously during the pressing process, and the ends of its columns are aligned with the ports of the feeding fixture in the vertical projection direction, further improving the reliability of the connection.

[0043] Furthermore, to enhance the controllability and safety of the crimping process, a limiting structure 509 is provided between the buffer plate 506 and the pressure plate 505. One end of the limiting structure 509 is fixed to the central area of ​​the buffer plate 506, and the other end extends upward and points towards the pressure plate 505, maintaining a distance from the pressure plate 505. When the buffer structure 510 is compressed during the crimping process, the limiting structure 509 can limit the maximum displacement of the buffer plate 506 relative to the pressure plate 505, preventing excessive buffering that could lead to the pressure head 508 exceeding its travel limit or difficulty in resetting, thereby effectively protecting the crimping assembly 503 from mechanical damage and ensuring the long-term stability and repeatability of the equipment.

[0044] Furthermore, the machine body 1, serving as the support and functional integration platform for the entire device, includes a housing 103, a feeding device 102, and a frame 101. A feeding port communicating with the upper surface is provided on the side of the housing 103, and a feeding tray inclined downwards is installed in the feeding port; the processed wire harness is fed out through this feeding port and falls into a transfer box for storage and transport.

[0045] The housing 103 is equipped with a drive motor that is connected to the indexing plate 205. The drive motor drives the indexing plate 205 to rotate, ensuring that each work area is accurately switched to each functional station, and meeting the timing requirements of multi-station synchronous operation.

[0046] Furthermore, the machine body 1 is also equipped with a human-machine interface and monitoring component, including a touch screen 8, a pressure sensor 7, and several control buttons. The touch screen 8 is mounted on the frame 101 of the machine body 1 and is used to display the equipment's operating status and parameter settings, supporting intuitive monitoring and parameter adjustment by operators. The control buttons are used for basic operations such as start, stop, emergency stop, and reset, meeting local manual control needs. The pressure sensor 7 is integrated into the crimping assembly 503 to monitor the applied force during the crimping process in real time.

[0047] Furthermore, the working process of this device is as follows: The operator first sets and adjusts the crimping process parameters via the touch screen 8 on the machine body 1. Then, the assembled wire harness to be processed is placed in the feeding fixture corresponding to the loading station 201, which is the initial loading station.

[0048] Press the first start button 8 and the second start button 9 simultaneously with both hands to start the equipment. The indexing plate 205 rotates 90° counterclockwise under the drive motor, moving the feeding fixture containing the wire harness to be processed from the loading station 201 to the inspection station 202, where it enters the inspection area. At this time, the inspection mechanism 3 located next to this station starts, and its four photoelectric sensors 301 perform non-contact inspection of the assembly status at both ends of the wire harness to be processed, automatically identifying whether the wire harness is correctly positioned.

[0049] If the test fails, the control system will issue an audible and visual alarm, and the indexing plate 205 will stop operating. Manual intervention is required to resolve the abnormality before operation can continue. If the test passes, the operator will press both start buttons simultaneously with both hands, and the indexing plate 205 will continue to rotate 90° counterclockwise, transferring the wire harness to the processing station 203 and into the processing area.

[0050] When the wire harness arrives at the processing station 203, the operator presses the first start button 8 and the second start button 9 simultaneously with both hands, and the positioning mechanism 4 starts: the side pressure servo motors 401 on both sides drive the positioning clamping component 403 to move synchronously to the center along the transverse guide rail, and the positioning extension arm 407 accurately positions and clamps the double-end connectors of the wire harness to be processed, ensuring that the position of the wire harness to be processed is stable and without deviation during the crimping process.

[0051] Subsequently, the connecting mechanism 5 operates: the pressing servo motor 501 drives the crimping assembly 503 downward along the vertical guide rail, and the pressing head 508 and the gantry bracket 507 press down synchronously, performing a double-end non-contact, solderless, insulated displacement connection operation on the wire harness to be processed, achieving one-time synchronous crimping. During the crimping process, the integrated pressure sensor 7 monitors the crimping force value in real time to ensure the consistency and reliability of the connection quality.

[0052] After crimping is completed, the connecting mechanism 5 automatically rises and resets, and the positioning mechanism 4 releases and returns to its initial position, completing one crimping cycle.

[0053] Subsequently, the operator presses both start buttons twice simultaneously, causing the indexing plate 205 to rotate counterclockwise by 90° between two positions, returning sequentially to the preparatory position 204 and the loading position 201. This allows the processed wire harness to return to its initial loading position along with the feeding fixture. At this point, the wire harness slides out through the discharge port on the side of the housing 103, is automatically fed out along the inclined discharge tray, and falls into the transfer box, completing the collection and transfer process.

[0054] When batch continuous production is required, during the cyclic operation of the indexing plate 205, the operator can alternately feed materials into the feeding fixtures placed on the preparation station 204, processing station 203, inspection station 202 and feeding station 201, so as to realize the parallel operation of each process of "feeding-inspection-processing-discharging".

[0055] The machine body 1 is also equipped with an emergency brake button 10 and a reverse feed button 11, which can be activated under special working conditions to perform corresponding emergency operations.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
