Description

Technical Field

[0001] This invention relates to the field of wire harness assembly technology, and in particular to a new energy wire harness mounting machine and a control method for the mounting machine. Background Technology

[0002] New energy vehicles have a complex network of electrical wires inside. As the main network of the vehicle's circuitry, these wires need to be arranged in a reasonable and orderly manner, which requires the use of wire harnesses to organize and manage the wires.

[0003] A wire harness is an assembly consisting of copper contact terminals crimped to wires and cables, then covered with an insulator or an outer metal shell, and bundled together to form a circuit connection. The wire harness industry chain includes wires and cables, connectors, processing equipment, wire harness manufacturing, and downstream application industries. Wire harnesses have a very wide range of applications.

[0004] A typical wire harness assembly includes components such as a cable, sheath, wire harness terminals, end cap, front cap, and upper pressure ring. These components are assembled and pressed together to form a finished wire harness assembly. The sheath includes at least two connection ports, typically located at opposite ends of the sheath. During wire harness assembly, the upper pressure ring has tolerance requirements; qualified products must be within these tolerances.

[0005] Currently, various wiring harnesses used in new energy vehicles still face the following technical challenges in wiring harness assembly:

[0006] (1) The wire harness is mostly assembled manually. Multiple parts are divided into different assembly steps, which is cumbersome. The rework rate of manual assembly is high, and the products cannot be repaired, resulting in an extremely high scrap rate.

[0007] (2) Some of the auxiliary tools for wire harness installation disclosed are not intelligent enough and cannot assemble the various components in the wire harness at one time. The reason is that the sheath has many ports, making it inconvenient to position the sheath. The cable is inconvenient to place, affecting the operation of the driving device. The wire harness terminals and the tail cap enter the sheath one after the other, and the driving devices of the two interfere with each other.

[0008] (3) The assembly accuracy is not high, and the stroke and force of insertion, extrusion and installation cannot be controlled. There is no detection system, so the assembly error of the upper pressure ring cannot be detected. Summary of the Invention

[0009] In view of the above situation and to overcome the defects of the prior art, the present invention provides a new energy wire harness installation machine to solve the problems of high labor intensity and high scrap rate of manual wire harness installation, and the inability of current auxiliary wire harness installation tools to complete the assembly of the entire set of components in one go.

[0010] In a first aspect, the present invention discloses a new energy wiring harness insertion machine, comprising a main body of equipment, an operating table on the main body of equipment, the operating table being used to place the wiring harness assembly to be inserted, the wiring harness assembly comprising a cable, a sheath, a wiring harness terminal, a tail cover, a front cover, and an upper pressure ring, characterized in that the main body of equipment is provided with a set of double slide rails for guiding the displacement direction of a first propulsion mechanism and a second propulsion mechanism, the left end of the double slide rails being provided with a positioning block, the positioning block having a slot adapted to the contour of the sheath for fixing the sheath and positioning the wiring harness in a fixed position;

[0011] The main body of the equipment is equipped with three sets of execution units, namely a pressure ring mechanism, a first propulsion mechanism, and a second propulsion mechanism.

[0012] The pressure ring mechanism is located at the rear end of the operating table. The pressure ring mechanism includes a screw jack and a pressing module fixedly connected to a moving platform on the screw jack. A servo motor is driven to the screw jack. The pressing module is located directly above the fixed base. The pressing module is provided with an upper pressing block for assembling the upper pressure ring. The upper pressing block is perpendicular to the slot. When the pressing module moves downward, the upper pressing block squeezes the upper pressure ring into the upper port of the sheath.

[0013] The first propulsion mechanism includes a first set of sliders slidably connected to a double slide rail, a first cylinder for controlling the displacement of the first set of sliders, a finger cylinder fixedly connected to the first set of sliders, and stepped sleeves fixedly connected to the two grippers of the finger cylinder. When the two grippers are closed, the two stepped sleeves are sleeved outside the cable and used to push the wire harness terminal to move into the lower port of the sheath.

[0014] The second propulsion mechanism includes a second set of sliders slidably connected to a double slide rail, and a second cylinder for controlling the displacement of the second set of sliders. The second set of sliders is located to the right of the first set of sliders, and a stop is fixedly connected to the second set of sliders. The stop is used to push the tail cover.

[0015] When the two grippers in the finger cylinder separate, the stop can pass between the two grippers;

[0016] The main body of the device is equipped with a main controller module, an image acquisition module, and a solenoid valve group. The image acquisition module, the solenoid valve group, and the servo motor are respectively communicatively connected to the main controller module.

[0017] The image acquisition module is used to acquire image information of the sheath inside the card slot;

[0018] One end of the solenoid valve assembly is connected to an external air source via an air source regulating switch, and the three passages in the solenoid valve assembly are respectively connected to the first cylinder, the second cylinder, and the finger cylinder.

[0019] Secondly, the present invention discloses a control method for a wire harness insertion machine, which is applied to the above-mentioned new energy wire harness insertion machine, including the following steps: receiving image information of the sheath in the slot and identifying the feature information of the wire harness to be inserted;

[0020] Based on the sheath feature information, the insertion depth and applied force values ​​of the corresponding wire harness components are read, including the insertion depth and applied force values ​​of the upper pressure ring, the insertion depth and applied force values ​​of the wire harness terminals, and the insertion depth and applied force values ​​of the tail cap.

[0021] Based on the wearing depth value and the applied force value, the displacement information of the corresponding execution unit is obtained, including the displacement information of the pressing module in the pressure ring mechanism, the displacement information of the stepped sleeve in the first propulsion mechanism, and the displacement information of the stop in the second propulsion mechanism.

[0022] Based on the displacement information, control the displacement of the screw jack, the first cylinder, the second cylinder, and the finger cylinder;

[0023] The pressure value on the execution unit is detected, and the execution unit stops operating when the pressure value exceeds the applied force value.

[0024] Compared with existing known technologies, the technical solution provided by this invention has the following significant advantages:

[0025] 1. By coordinating the pressure ring mechanism, the first propulsion mechanism, and the second propulsion mechanism, and using a pneumatic and servo-driven setup, the depth and force of inserting the upper pressure ring, wire harness terminals, and tail cap are precisely controlled. This replaces manual labor and allows the wire harness assembly to be inserted in one go. It has advantages such as high yield rate, prevention of missing parts, and adjustable position.

[0026] 2. By opening a working slot on the operating platform, the execution components of the pressure ring mechanism, the first propulsion mechanism and the second propulsion mechanism can all correspond to the designated parts on the wire harness assembly. By setting a positioning block in the working slot, the sheath is fixedly positioned by using the slot on the positioning block. One port on the sheath faces upward and the other port faces to the side, which facilitates the placement of the wire harness assembly on the operating platform and provides feasibility for the automatic wire harness insertion of the execution unit.

[0027] 3. By setting up the image acquisition module and pressure sensor, an automatic control system can be built. It can automatically retrieve the installation data of the sheath assembly according to the type of sheath. It has a high degree of intelligence. With the help of the pressure sensor, it can achieve automatic feedback and prevent excessive pressure from damaging the wire harness assembly. Attached Figure Description

[0052] refer to Figure 6 The aforementioned wire harness assembly 100 includes a cable 101, a sheath 102, a wire harness terminal 103, a tail cover 104, a front cover, and an upper pressure ring 105. The aforementioned equipment body 200 is provided with three sets of execution units, namely a pressure ring mechanism 300, a first propulsion mechanism 400, and a second propulsion mechanism 500, which are used to install the upper pressure ring 105, the wire harness terminal 103, and the tail cover 104 of the wire harness assembly 100.

[0053] The main body 200 of the above-mentioned equipment is provided with a set of double slide rails 202, which are used to guide the displacement direction of the first propulsion mechanism 400 and the second propulsion mechanism 500. The left end of the double slide rails 202 is provided with a positioning block 203. The positioning block 203 is provided with a slot 204 that matches the contour of the sheath 102, which is used to fix the sheath 102 and the positioning wire harness in the placement posture. Specifically, the wire harness assembly 100 is placed horizontally on the operating table 201, with the upper end of the sheath 102 facing upward and the lower end of the sheath 102 facing right.

[0054] Furthermore, a manually adjustable pressure plate (not shown in the figure) can be installed on the operating table 201 to compress the cable 101 and prevent the wire harness assembly 100 from deviating or misaligning during installation.

[0055] In some embodiments, reference Figure 2 and Figure 5 The aforementioned pressing ring mechanism 300 is located at the rear end of the operating table 201. The pressing ring mechanism 300 includes a screw jack 301 and a pressing module 302 fixedly connected to a moving platform 3011 on the screw jack 301. A servo motor 303 is drivenly connected to the screw jack 301. The pressing module 302 is located directly above the fixed base. The pressing module 302 is provided with an upper pressing block 304 for assembling the upper pressing ring 105. The upper pressing block 304 is perpendicularly corresponding to the slot 204. When the pressing module 302 moves downward, the upper pressing block 304 presses the upper pressing ring 105 into the upper port of the sheath 102.

[0056] Specifically, the aforementioned pressing module 302 includes a square frame consisting of a connecting plate 3021, two vertical plates 3022, and a horizontal plate 3023. The connecting plate 3021 is fixedly connected to the moving platform 3011 on the aforementioned screw jack 301. An upper pressing block 304 is detachably connected to the lower end of the horizontal plate 3023. The upper pressing block 304 can be replaced with different models to adapt to different types of upper pressing rings 105. The assembly of the upper pressing rings 105 can be automated, with one upper pressing ring 105 being assembled onto the upper pressing block 304 at a time, or it can be manually assembled onto the upper pressing block 304. The lower end of the horizontal plate 3023 is provided with a transparent protective shell 3024 surrounding the upper pressing block 304. The square frame moves synchronously with the moving platform 3011, accurately bringing the upper pressing rings 105 into the upper port of the protective sleeve 102.

[0057] Furthermore, the outer side of the aforementioned screw jack 301 is provided with a transparent protective cover 305, which allows for manual observation of the pressing module 302 and facilitates the assembly of the pressing ring.

[0058] In some embodiments, reference Figure 2 and Figure 3 The first propulsion mechanism 400 includes a first set of sliders 401 slidably connected to the double slide rails 202, a first cylinder 402 for controlling the displacement of the first set of sliders 401, a finger cylinder 403 fixedly connected to the first set of sliders 401, and two claws 4031 of the finger cylinder 403 respectively fixedly connected to stepped sleeves 4032. The two stepped sleeves 4032 can be combined into a whole. When the two claws 4031 are combined, the two stepped sleeves 4032 are combined and sleeved on the outside of the cable 101, which is used to push the wire harness terminal 103 to move into the lower port of the sheath 102.

[0059] In some embodiments, reference Figure 2 and Figure 3 The second propulsion mechanism 500 includes a second set of sliders 501 slidably connected to the double slide rail 202 and a second cylinder 502 for controlling the displacement of the second set of sliders 501. The second set of sliders 501 is located to the right of the first set of sliders 401. A stop 503 is fixedly connected to the second set of sliders 501. The stop 503 is used to push the tail cover 104. When the two grippers 4031 in the finger cylinder 403 separate, the stop 503 can pass between the two grippers 4031.

[0060] In some embodiments, reference Figure 4 and Figure 7The main body 200 of the aforementioned device is equipped with a main controller module 601, an image acquisition module 602, and a solenoid valve group 603. The image acquisition module 602, the solenoid valve group 603, and the servo motor 303 are respectively connected to the main controller module 601. The camera component 6021 in the image acquisition module 602 is located at the lower end of the pressure module 302 and is used to acquire image information of the sheath 102 inside the card slot 204.

[0061] Specifically, one end of the solenoid valve assembly 603 is connected to an external air source via an air source regulating switch 604. The three passages in the solenoid valve assembly 603 are respectively connected to the first cylinder 402, the second cylinder 502 and the finger cylinder 403. The main controller module 601 can control the solenoid valve assembly 603 to control the movement of the finger cylinder.

[0062] Furthermore, each of the three aforementioned execution units is equipped with a pressure detection module 605. Specifically, the lower end of the upper pressure block 304 in the aforementioned pressure ring mechanism 300 is equipped with a pressure sensor A, the left end of the stepped sleeve 4032 in the aforementioned first propulsion mechanism 400 is equipped with a pressure sensor B, and the left end of the stop 503 in the second propulsion mechanism 500 is equipped with a pressure sensor C. The pressure detection module 605 serves as a feedback unit to monitor the pressure exerted by the execution unit on the wiring harness assembly 100, preventing excessive pressure from damaging the wiring harness assembly 100.

[0063] The main body 200 of the equipment is equipped with an electrical cabinet 205. A display 606 is installed on the top of the electrical cabinet 205. The electrical cabinet 205 also contains a power module 607 and a leakage current protector 608. The display 606, power module 607 and leakage current protector 608 are electrically and communicatively connected to the main controller module 601. The main controller module 601 is communicatively connected to a transmission unit 609 and a storage unit 610, which supports recording real-time processing logs. All data of the processed wire harness is saved in the system, and the background can add, delete and save as. Through the transmission unit, it can interact with the MES system to realize remote control.

[0064] Furthermore, the storage unit pre-stores basic information of different types of wire harness assemblies, including the shape, size, number of assemblies, and the insertion depth and applied force values ​​corresponding to the wire harness assemblies.

[0065] In order to properly position the two cylinders within the main body 200 of the equipment, a fixing plate 209 and a reinforcing inclined plate 210 are fixedly connected within the main body 200. The fixing plate 209 is located at the right end of the double slide rail 202, and the reinforcing inclined plate 210 is vertically fixedly connected to one end of the fixing plate 209. The first cylinder 402 and the second cylinder 502 are respectively fixedly connected to the fixing plate 209, with the first cylinder 402 located above the second cylinder 502. The cylinders, the solenoid valve group 603, and the air source regulating switch 604 are arranged on the same side of the main body 200 for convenient pipe connection.

[0066] To prevent interference between the first and second pushing mechanisms, a second push plate 504 is fixedly connected to the right end of the second set of sliders 501, and the piston rod of the second cylinder 502 is fixedly connected to the second push plate 504. An obstacle hole 505 is provided on the second push plate 504, and a first push plate 404 is fixedly connected to the right end of the first set of sliders 401. The piston rod of the first cylinder 402 passes through the obstacle hole 505 and is fixedly connected to the first push plate 404.

[0067] To further ensure the reliability of the equipment, the main body 200 of the aforementioned equipment is equipped with two stroke adjustment blocks 701 located outside the double slide rails 202. The two stroke adjustment blocks 701 are located on the left and right sides of the finger cylinder 403, respectively. First adjustment bolts 702 are threaded onto the stroke adjustment blocks 701. Changing the insertion depth of the first adjustment bolts 702 changes the displacement of the first pushing mechanism. It can be set so that when the first set of sliders 401 moves to the left to a specified depth and reaches the pressure value, the first set of sliders 401 is blocked by the first adjustment bolts 702. It serves as a limit; a protrusion 703 is fixedly connected to the outer side of the second push plate 504. The protrusion 703 is offset from the first adjusting bolt 702. A second adjusting bolt 704 is threaded onto the protrusion 703. The second adjusting bolt 704 is used and functions in the same way as the first adjusting bolt 702. The second adjusting bolt 704 blocks the stroke adjusting block 701, which can limit the further movement of the second set of sliders 501 and prevent the sleeve 102 from being damaged due to excessive displacement in case of operational errors.

[0068] This invention also provides a method for threading a wire harness, applied to the aforementioned threading machine, such as... Figure 8 The diagram shows a flowchart 800 illustrating some embodiments of the control method for a threading machine provided by the present invention. The method may include the following steps:

[0069] Step 801: Receive image information of the sheath inside the card slot and identify the feature information of the wire harness to be installed;

[0070] In some embodiments, the execution subject of the control method may be an image acquisition module, which acquires image information of the sheath and transmits the image information to the main controller module to identify the feature information of the sheath.

[0071] Step 802: Based on the sheath feature information, read the insertion depth value and applied force value of the corresponding wire harness assembly, including the insertion depth value and applied force value of the upper pressure ring, the insertion depth value and applied force value of the wire harness terminal and the insertion depth value and applied force value of the tail cap.

[0072] In some embodiments, the storage unit within the main controller module pre-stores feature information of various sheaths and classifies different sheaths. Based on the wire harness component corresponding to each sheath, a fixed insertion depth value and applied force value are set. According to the collected sheath feature information, the corresponding wire harness component in the storage unit can be found, and the insertion depth value and applied force value of the corresponding wire harness component can be called.

[0073] Step 803: Based on the above-mentioned wearing depth value and applied force value, obtain the displacement information of the corresponding execution unit, including the displacement information of the pressing module in the pressure ring mechanism, the displacement information of the stepped sleeve in the first propulsion mechanism, and the displacement information of the stop in the second propulsion mechanism.

[0074] In some embodiments, the main controller module converts the wearing depth value and the applied force value into the displacement in the execution unit.

[0075] Step 804: Based on the above displacement information, control the displacement of the screw jack, the first cylinder, the second cylinder, and the finger cylinder;

[0076] In some embodiments, the three execution units execute the set displacement amount according to the following steps:

[0077] Step 1: The finger cylinder gripper closes, and the two stepped sleeves merge.

[0078] Step 2: The piston rod of the first cylinder extends, and the stepped sleeve pushes the wire harness terminal into the lower port of the sheath;

[0079] Step 3: The moving platform on the screw jack descends, and the upper pressure block moves downward to push the upper pressure ring into the upper port of the sheath;

[0080] Step 4: The piston rod of the first cylinder retracts, and the stepped sleeve exits from the lower port of the sheath.

[0081] Step 5: Separate the finger cylinder gripper and separate the two stepped sleeves;

[0082] Step 6: The piston rod of the second cylinder extends, and the stopper pushes the tail cover into the lower port of the sleeve;

[0083] Step 7: The piston rod of the second cylinder retracts, and the stopper moves away;

[0084] Step 8: The finger cylinder gripper closes, and the two stepped sleeves merge.

[0085] Step 9: The moving platform on the screw jack rises and the upper pressure block moves away;

[0086] Step 10: Separate the finger cylinder gripper and the two stepped sleeves.

[0087] By following the steps described above, the wire harness terminals, upper pressure ring, and tail cap in the wire harness assembly are installed sequentially without any interference. The wire harness assembly remains stably positioned on the operating table, ensuring smooth installation of the wire harness assembly.

[0088] Step 805: Detect the pressure value on the execution unit. When the pressure value is greater than the applied force value, stop the action of the execution unit.

[0089] In some embodiments, the execution subject of the control method can be a pressure sensor. When the execution unit moves, if the pressure value detected is greater than the applied force value, the information is sent to the main controller module, and the main controller module sends a stop signal to the servo motor or solenoid valve group.

[0090] The above-described embodiments of the present invention have the following beneficial effects: Through the coordinated arrangement of the pressure ring mechanism, the first propulsion mechanism, and the second propulsion mechanism, and employing a pneumatic and servo-driven setup, the depth and force of inserting the pressure ring, wire harness terminals, and tail cap are precisely controlled, replacing manual labor. This allows for the one-time completion of wire harness assembly insertion, resulting in high yield, prevention of missed insertion, and adjustable position. By opening a working slot on the operating platform, the execution components of the pressure ring mechanism, the first propulsion mechanism, and the second propulsion mechanism can all correspond to designated positions on the wire harness assembly. By setting a positioning block within the working slot, the sheath is fixedly positioned using its slots, with one port on the sheath facing upwards and the other facing sideways, facilitating the placement of the wire harness assembly on the operating platform and providing feasibility for automatic wire harness insertion by the execution unit. By setting an image acquisition module and a pressure sensor, an automatic control method is established, which can automatically retrieve insertion data of the sheath assembly according to the sheath type, providing intelligent identification, remote control, and safety protection functions, thus improving the convenience and safety of production. In practical applications, this software can effectively realize intelligent management of factory equipment, improve production quality, and has broad application prospects.
