Technical Field

[0001] The present invention relates to the technical field of wire harness processing, and in particular to a new energy vehicle wire harness processing device and process with a waterproof sealing structure. Background Art

[0002] At a time when the new energy vehicle industry is booming, the performance of automotive wiring harnesses, as key components that connect various electrical devices in a car, is directly related to the safety and reliability of the entire vehicle. Since the power system and control system of new energy vehicles are highly dependent on power transmission, strict requirements are placed on the waterproof and sealing performance of the wiring harness.

[0014] As a preferred technical solution of the device of the present invention: a plurality of card slots are arranged on the top side of the bottom mold, and a plurality of card blocks matching with the card slots are arranged on the bottom side of the top mold.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] Embodiment 1: The present invention designs a new energy vehicle wiring harness processing device with a waterproof sealing structure, and the specific structural configuration is as follows:

[0039] (I) Overall architecture and core components: see Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 ,in, Figure 7 The AA and arrows in the figure are for Figure 7 The direction of the cutaway view showing the structure. The cutaway view is Figure 8 The processing device is mainly composed of key components such as a base member 1, a bottom mold member 2, a top mold member 7, a wiring harness terminal member 6 and a motor 8. The base member 1 serves as the basic supporting structure of the entire device, and the bottom mold member 2 is installed on its upper side to ensure the stability and accuracy of the bottom mold member 2 during movement. The upper side of the bottom mold member 2 is engaged with the top mold member 7, and the wiring harness terminal member 6 is clamped between the two. The motor 8 is arranged below the base member 1 to provide power for the movement of the bottom mold member 2 and the top mold member 7.

[0040] (II) Design of wiring harness terminal parts: See Figure 2 , Figure 4 , the wiring harness terminal 6 includes a plug 601 and a wiring harness wire 602 electrically connected thereto. A conical groove 603 for inserting the wiring harness wire 602 is provided on the wiring harness terminal 6, and the design of this groove facilitates the insertion of the wiring harness wire 602. In the plane where the conical groove 603 is located, a plurality of trapezoidal grooves 604 are horizontally distributed, and the outward openings of these trapezoidal grooves 604 gradually shrink. When the waterproof glue is injected, the trapezoidal groove 604 can limit the external waterproof glue in an embedded form, so that the waterproof glue can be better attached to the conical groove 603, and the close contact between the waterproof glue and the conical groove 603 is enhanced, thereby improving the waterproof performance. A frame-shaped protrusion 605 is arranged between adjacent conical grooves 603, and the frame-shaped protrusion 605 is provided with an inner peripheral notch 6051 connected to the trapezoidal groove 604, and its outer plate is also provided with an outer peripheral notch 6052 connected to the inner peripheral notch 6051. The inner notch 6051 formed by the frame-shaped protrusion 605 can directly limit the waterproof glue attached to the surface of the wiring harness terminal 6 to prevent the waterproof glue from flowing freely; and the outer notch 6052 can quickly fill the inner notch 6051 with the external waterproof glue during glue injection and compaction, ensuring that the waterproof glue can be evenly distributed and tightly fit the wiring harness terminal 6 and the conical groove 603 for inserting the wiring harness wire 602, effectively blocking moisture intrusion.

[0041] 3. Collaborative design of various components

[0042] Guide cooperation between base part and bottom mold part: see Figure 1 , Figure 2 The upper side of the base member 1 is provided with a plurality of parallel guide rails 102, and the bottom side of the bottom mold member 2 is provided with guide grooves 205 that match the guide rails 102. The matching mode of the guide rails 102 and the guide grooves 205 ensures the stability and accuracy of the bottom mold member 2 during the movement, thereby ensuring the stable position of the wiring harness terminal member 6 during the processing, laying the foundation for subsequent accurate processing operations.

[0043] Wiring harness wire positioning design: see Figure 2 , Figure 3The bottom mold 2 is provided with a lower wire notch 201, and the top mold 7 is provided with an upper wire notch 701 aligned with the lower wire notch 201. When the bottom mold 2 and the top mold 7 are clamped with the wiring harness terminal 6, the wiring harness wire 602 is clamped exactly between the lower wire notch 201 and the upper wire notch 701, thus achieving accurate positioning of the wiring harness wire 602 and preventing displacement of the wiring harness wire 602 during processing, thereby affecting the quality of the waterproof sealing structure.

[0044] Connection structure between bottom mold and cross frame: see Figure 2 , Figure 3 , a horizontal frame 3 connected to the bottom mold 2 is arranged below the base member 1. Side plates 206 are arranged on both sides of the bottom mold 2, and fixing holes 2061 are opened on the side plates 206. Fixing screw holes 301 matching the fixing holes 2061 are opened on both sides of the horizontal frame 3. At the aligned fixing holes 2061 and fixing screw holes 301, the bottom mold 2 is firmly connected to the horizontal frame 3 by tightening the fixing bolts 4 to ensure that the bottom mold 2 will not loosen during the processing.

[0045] Motor drive structure: see Figure 3 , Figure 5 , Figure 6 , Figure 8 The output side of the motor 8 is connected to a screw rod 801 for driving the horizontal frame 3 to move. A driving screw hole 302 is provided in the middle of the horizontal frame 3, and the screw rod 801 is screwed through the driving screw hole 302. The bottom side of the base member 1 is provided with a bearing portion 103 that is matched and connected with the end of the screw rod 801. The setting of the bearing portion 103 can reduce the friction force when the screw rod 801 rotates, so that the motor 8 drives the horizontal frame 3 to move more smoothly. The motor 8 drives the screw rod 801 to rotate, thereby realizing precise movement control of the horizontal frame 3 and the bottom mold member 2 connected thereto.

[0046] Matching of stopper and guide rod: see Figure 2 , Figure 4 , Figure 5 The bottom mold 2 is provided with a group of blocks 203 for guiding the installation of the wiring harness terminal 6. The height dimension of the block 203 is the same as the height dimension of the wiring harness terminal 6, that is, the dimensioning relationship Ha=Hc, so that the wiring harness terminal 6 can be better supported and positioned. The block 203 is also provided with a slot 207 for active insertion with the guide rod 5. The guide rod 5 is installed on the limit plate 101. The limit plate 101 is located on one side of the base member 1 and abuts against the plug 601 of the wiring harness terminal 6. The guide rod 5 not only plays an auxiliary positioning role for the wiring harness terminal 6, but also can further ensure the stability of its movement during the movement of the bottom mold 2.

[0047] The snap-fit ​​structure between the bottom mold and the top mold: see Figure 1 , Figure 2 , Figure 3The top side of the bottom mold 2 is provided with a plurality of slots 204, and the bottom side of the top mold 7 is provided with a plurality of blocks 702 that match the slots 204. When the lifting frame 703 drives the top mold 7 to descend and engage with the bottom mold 2, the blocks 702 and the slots 204 cooperate with each other, which can further improve the positioning accuracy of the bottom mold 2 and the top mold 7 when clamping the wiring harness terminal 6, prevent displacement during the processing, and ensure the consistency and reliability of the waterproof sealing structure.

[0048] Connection structure between limit plate and guide rod: see Figure 1 , Figure 2 , Figure 5 The limiting plate 101 is provided with a group of positioning screw holes 104, one end of the guide rod 5 is provided with a threaded section 501 threadedly engaged with the positioning screw hole 104, and the threaded section 501 is threadedly engaged with a nut 502 for fastening the guide rod 5 to the limiting plate 101. This connection method makes the installation of the guide rod 5 more stable, and the position of the guide rod 5 can be fine-tuned by adjusting the nut 502 according to actual processing requirements.

[0049] (IV) Mold cavity and injection structure: see Figure 1 , Figure 2 , Figure 4 , Figure 8 A mold cavity 202 facing the wiring harness terminal 6 is provided between the bottom mold 2 and the top mold 7, and a lifting frame 703 and a glue injection pipe head 704 connected to the mold cavity 202 are arranged on the top of the top mold 7. During the processing, after the bottom mold 2 and the top mold 7 are clamped with the wiring harness terminal 6, the glue supply related equipment injects a certain amount of waterproof glue into the mold cavity 202 through the glue injection pipe head 704. The design of the mold cavity 202 can provide a specific filling space for the waterproof glue, ensuring that the waterproof glue can be fully filled into various waterproof structures of the wiring harness terminal 6 under pressure, such as the trapezoidal groove 604, the inner notch 6051, etc., to form a good sealing effect.

[0050] Embodiment 2: The present invention designs a new energy vehicle wiring harness processing technology with a waterproof sealing structure, and the specific process flow is as follows:

[0051] Step 1: Initial position setting: According to the length of the plug 601 of the wiring harness terminal 6, the initial distance between the bottom mold 2 and the limit plate 101 is preset, which is recorded as L1. The bottom mold 2 is driven by the motor 8 to move so that it reaches the initial position with a distance of L1 from the limit plate 101. This step can ensure that the plug 601 of the wiring harness terminal 6 is accurately positioned in the device during each processing, providing a unified benchmark for subsequent processing operations.

[0052] Step 2: Clamping of the wiring harness terminal: The wiring harness terminal 6 can be placed flat between the two blocks 203 of the bottom mold 2 by a manipulator or manually. During the placement process, the plug 601 of the wiring harness terminal 6 is pushed toward the limit plate 101 and abutted. At this time, the plug 601 is placed between the two blocks 203, and the wiring harness wires 602 are aligned one by one and placed in the gap 201 under the wire. This step realizes the preliminary positioning of the wiring harness terminal 6 on the bottom mold 2, ensuring its accurate position and facilitating subsequent processing operations.

[0053] Step 3: Glue injection operation: The lifting frame 703 drives the top mold 7 to descend, so that the top mold 7 is engaged with the bottom mold 2. At this time, the wire harness wire 602 is completely clamped between the lower wire notch 201 and the upper wire notch 701. Then, the glue supply related equipment injects a certain amount of waterproof glue into the mold cavity 202 through the glue injection pipe head 704. During the glue injection process, it is necessary to ensure that the injection amount of waterproof glue is accurate to ensure the quality of the subsequent waterproof sealing structure.

[0054] Step 4: Compacting operation: According to the parameters of the mold cavity 202, the length of the frame-shaped protrusion 605, the parameters of the tapered groove 603 and the trapezoidal groove 604, the motor 8 drives the bottom mold 2 to move toward the limit plate 101. When the moving distance reaches the preset distance ΔL, it stops. In this process, the waterproof glue can fully fill the trapezoidal groove 604, the inner notch 6051 and other structures under the action of pressure, ensuring that the waterproof glue is in close contact with various parts of the wiring harness terminal 6, further improving the waterproof sealing effect.

[0055] Step 5: Product removal: After the glue injection and compaction operations are completed, the product is left to stand for a preset time t to allow the waterproof glue to fully solidify. Then, the lifting frame 703 drives the top mold 7 to rise and return to the initial position before the glue injection, and the processed wiring harness terminal 6 is taken out by a manipulator or manually. The setting of the standing time t should be determined according to the characteristics of the waterproof glue and the actual production requirements to ensure that the waterproof glue can achieve the best curing effect.

[0056] Step 6: Equipment reset: Motor 8 drives bottom mold 2 to move back to the initial position to prepare for the next processing operation. This step ensures that the processing device can quickly enter the next round of processing flow and improve production efficiency.

[0057] Step 7: Circular processing: Repeat the operations of Steps 2 to 6 to achieve continuous processing of multiple wiring harness terminal pieces 6 to meet production needs.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
