Description

Technical Field

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

[0002] At present, with the booming development of the new energy vehicle industry, the automotive wire harness, as a key component connecting various electrical devices of the vehicle, its performance directly affects the safety and reliability of the whole vehicle. Since the power system, control system, etc. of new energy vehicles highly rely on power transmission, strict requirements are put forward for the waterproof sealing performance of the wire harness. If the waterproof sealing of the wire harness is not good, when the vehicle wades through water, is washed or encounters a humid environment, moisture is very easy to invade, resulting in electrical faults such as short circuits and open circuits, seriously threatening driving safety and even causing major accidents such as vehicle fires.

[0003] Traditional automotive wire harness processing devices and processes have many deficiencies in meeting the special requirements of new energy vehicles. For example, the application of the sealing waterproof glue often relies on manual operation or simple mechanical devices, with uneven glue layer thickness and poor continuity, making it difficult to ensure the formation of a reliable sealing barrier between the wire harness and the connector. During the assembly process of the waterproof sealing structure, the seals are prone to dislocation and deformation, reducing the waterproof effect of the wire harness.

Wherein, a driving screw hole is arranged at the middle position of the cross frame, the screw rod is screwed through the driving screw hole, and a bearing part for cooperatively connecting with the end of the screw rod is arranged on the bottom side of the base member.

[0013] As a preferred technical solution of the device of the present invention: the height dimension of the stopper is the same as the height dimension of the wire harness terminal part, and a slot for movably inserting and matching with the guide rod is opened on the stopper.

[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 die member, and a plurality of card blocks matching with the card slots are arranged on the bottom side of the top die member.

[0015] As a preferred technical solution of the device of the present invention: a group of positioning screw holes are opened on the limiting plate, a threaded section for screwing and matching with the positioning screw holes is arranged at one end of the guide rod, and a nut for tightly connecting the guide rod and the limiting plate is screwed on the threaded section.

[0016] The present invention also provides a new energy vehicle wire harness processing technology with a waterproof sealing structure, including the following contents:

[0017] S1. According to the plug length of the wire harness terminal part, preset the initial distance between the bottom die member and the limiting plate, denoted as L1, and the motor drives the bottom die member to move to the initial position with a distance of L1 from the limiting plate.

[0024] Compared with the existing technology, the beneficial effects of the present invention are as follows:

[0025] 1. In the present invention, the design of the tapered groove, trapezoidal groove, frame-shaped protrusion and its notch on the wire harness terminal part can significantly improve the waterproof performance: the trapezoidal groove limits the outer waterproof glue in an embedded form, enhancing the close contact between the waterproof glue and the tapered groove; the inner circumferential notch of the frame-shaped protrusion directly restricts the waterproof glue, and the outer notch facilitates the filling of the waterproof glue during the glue injection and compaction processes, ensuring that the waterproof glue can be evenly distributed and closely fit the wire harness terminal part and the tapered groove where the wire harness conductor is inserted, effectively blocking the intrusion of moisture.

[0026] 2. In the present invention, through the guiding cooperation between the base part and the bottom mold part, the movement of the bottom mold part is ensured to be stable and precise, ensuring the stable position of the wire harness terminal part during the processing. The bottom mold part and the top mold part cooperate with each other, and when clamping the wire harness terminal part, the positioning accuracy can be further improved, preventing displacement during the processing, thereby ensuring the consistency and reliability of the waterproof sealing structure.

[0027] 3. In the present invention, the initial distance between the bottom mold part and the limiting plate is preset according to the plug length of the wire harness terminal part. The bottom mold part is accurately driven to the initial position by the motor, and combined with the subsequent driving of the bottom mold part to move according to the preset parameters, the position of the wire harness terminal part is ensured to be accurate each time during processing, improving the processing accuracy and consistency. After glue injection, the bottom mold part is driven to move according to the relevant parameters of the cavity and the wire harness terminal part, so that the waterproof glue fully fills structures such as the trapezoidal groove and the inner circumferential notch under the action of pressure, ensuring the close contact between the waterproof glue and each part of the wire harness terminal part, and forming a good sealing effect.

Detailed implementation manners

[0037] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to 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 used to limit the present invention.

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

[0039] (I) Overall architecture and core components: Refer to Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 , wherein, Figure 7 The A-A marked and the arrow in Figure 7 are the sectional view direction of the cross-section of the displayed structure, and the sectional view is alsoFigure 8 This processing device is mainly composed of key components such as a base part 1, a bottom die part 2, a top die part 7, a wire harness terminal part 6, and a motor 8. The base part 1 serves as the basic support structure of the entire device, and the bottom die part 2 is guided and installed above it to ensure the smoothness and accuracy of the bottom die part 2 during movement. The upper side of the bottom die part 2 is engaged with the top die part 7, and the wire harness terminal part 6 is clamped between them. The motor 8 is arranged below the base part 1 to provide power for the movement of the bottom die part 2 and the top die part 7.

[0040] (2) Design of the wire harness terminal part: Refer to Figure 2 、 Figure 4 As shown in the figure, the wire harness terminal part 6 includes a plug 601 and a wire harness wire 602 electrically connected thereto. On the wire harness terminal part 6, a tapered groove 603 for inserting the wire harness wire 602 is provided, and the design of this groove facilitates the insertion of the wire harness wire 602. In the plane where the tapered groove 603 is located, a plurality of trapezoidal grooves 604 are horizontally distributed, and the outer openings of these trapezoidal grooves 604 gradually narrow. When injecting waterproof glue, the trapezoidal grooves 604 can limit the external waterproof glue in an embedded form, enabling the waterproof glue to better adhere around the tapered groove 603, enhancing the close contact degree between the waterproof glue and the tapered groove 603, and thus improving the waterproof performance. A frame-shaped protrusion 605 is provided between adjacent tapered grooves 603. The frame-shaped protrusion 605 is provided with an inner peripheral notch 6051 communicating with the trapezoidal groove 604, and at the same time, its outer side plate is also provided with an outer side notch 6052 communicating with the inner peripheral notch 6051. The inner peripheral notch 6051 opened in the frame-shaped protrusion 605 can directly limit the waterproof glue attached to the surface of the wire harness terminal part 6 to prevent the waterproof glue from flowing randomly; while the outer side notch 6052 can quickly fill the inner peripheral notch 6051 with external waterproof glue during glue injection and compaction, ensuring that the waterproof glue can be evenly distributed and closely fit the wire harness terminal part 6 and the tapered groove 603 of the inserted wire harness wire 602, effectively blocking the intrusion of moisture.

[0041] (3) Coordinated working design of each component

[0042] Guided cooperation between the base part and the bottom die part: Refer to Figure 1 、 Figure 2 As shown in the figure, a plurality of parallel distributed guide rails 102 are provided on the upper side of the base part 1, and guide grooves 205 matching the guide rails 102 are opened on the bottom side of the bottom die part 2. This matching method of the guide rails 102 and the guide grooves 205 ensures the smoothness and accuracy of the bottom die part 2 during movement, and further ensures the stable position of the wire harness terminal part 6 during the processing, laying a foundation for subsequent precise processing operations.

[0043] Positioning design of the wire harness wire: Refer to Figure 2 、 Figure 3, the bottom die member 2 is provided with a wire lower notch 201, and the top die member 7 is provided with a wire upper notch 701 aligned with the wire lower notch 201. When the bottom die member 2 and the top die member 7 clamp the wire harness terminal member 6, the wire harness wire 602 is exactly clamped between the wire lower notch 201 and the wire upper notch 701, achieving precise positioning of the wire harness wire 602 and preventing the wire harness wire 602 from shifting during the processing, which affects the quality of the waterproof sealing structure.

[0044] Connection structure between the bottom die member and the cross frame: Refer to Figure 2 , Figure 3 , a cross frame 3 connected to the bottom die member 2 is arranged below the base member 1. Side plates 206 are provided on both sides of the bottom die member 2, and fixing through holes 2061 are provided on the side plates 206. Fixing screw holes 301 matched with the fixing through holes 2061 are provided at both ends of the cross frame 3. At the positions of the aligned fixing through holes 2061 and fixing screw holes 301, the bottom die member 2 and the cross frame 3 are firmly connected by tightly installing fixing bolts 4, ensuring that the bottom die member 2 will not loosen during the processing.

[0045] Motor drive structure: Refer to Figure 3 , Figure 5 , Figure 6 , Figure 8 , a screw rod 801 for driving the cross frame 3 to move is connected to the output side of the motor 8. A driving screw hole 302 is provided at the middle position of the cross frame 3, and the screw rod 801 is screwed through the driving screw hole 302. A bearing part 103 for cooperating with the end of the screw rod 801 is provided at the bottom side of the base member 1. The setting of the bearing part 103 can reduce the friction force when the screw rod 801 rotates, making the motor 8 drive the cross frame 3 to move more smoothly. By driving the screw rod 801 to rotate through the motor 8, precise movement control of the cross frame 3 and the bottom die member 2 connected thereto is realized.

[0046] Cooperation between the stop block and the guide rod: Refer to Figure 2 , Figure 4 , Figure 5 , the bottom die member 2 is provided with a set of stop blocks 203 for guiding and installing the wire harness terminal member 6. The height dimension of the stop blocks 203 is the same as the height dimension of the wire harness terminal member 6, that is, the dimension marking relationship is Ha = Hc, which can better support and position the wire harness terminal member 6. The stop blocks 203 are also provided with slots 207 for movably inserting and cooperating with the guide rod 5. The guide rod 5 is installed on the limit plate 101, and the limit plate 101 is located on one side of the base member 1 and abuts against the plug 601 of the wire harness terminal member 6. The guide rod 5 not only plays an auxiliary positioning role for the wire harness terminal member 6, but also can further ensure the stability of its movement during the movement of the bottom die member 2.

[0047] Engaging structure between the bottom die member and the top die member: Refer to Figure 1 , Figure 2 , Figure 3, on the top side of the bottom mold part 2, there are a plurality of card slots 204, and on the bottom side of the top mold part 7, there are a plurality of clamping blocks 702 that cooperate with the card slots 204. When the lifting frame 703 drives the top mold part 7 to descend and engage with the bottom mold part 2, the clamping blocks 702 and the card slots 204 cooperate with each other, which can further improve the positioning accuracy when the bottom mold part 2 and the top mold part 7 clamp the wire harness terminal part 6, prevent displacement during the processing, and ensure the consistency and reliability of the waterproof seal structure.

[0048] Connection structure between the limit plate and the guide rod: Refer to Figure 1 , Figure 2 , Figure 5 , the limit plate 101 is provided with a set of positioning screw holes 104, one end of the guide rod 5 is provided with a threaded section 501 that is screwed and matched with the positioning screw holes 104, and a nut 502 for fastening the connection between the guide rod 5 and the limit plate 101 is screwed on the threaded section 501. This connection method makes the installation of the guide rod 5 more stable, and the position of the guide rod 5 can be finely adjusted by adjusting the nut 502 according to the actual processing requirements.

[0049] (Four) Mold cavity and glue injection structure: Refer to Figure 1 , Figure 2 , Figure 4 , Figure 8 , there is a mold cavity 202 facing the wire harness terminal part 6 between the bottom mold part 2 and the top mold part 7, and the top of the top mold part 7 is configured with a lifting frame 703 and a glue injection pipe head 704 communicating with the mold cavity 202. During the processing, after the bottom mold part 2 and the top mold part 7 clamp the wire harness terminal part 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 under the action of pressure, the waterproof glue can fully fill into each waterproof structure of the wire harness terminal part 6, such as the trapezoidal groove 604, the inner peripheral notch 6051, etc., to form a good sealing effect.

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

[0051] Step One, initial position setting: According to the length of the plug 601 of the wire harness terminal part 6, preset the initial distance between the bottom mold part 2 and the limit plate 101, denoted as L1. Drive the bottom mold part 2 to move through the motor 8 so that it reaches the initial position with a distance of L1 from the limit plate 101. This step can ensure that the position of the plug 601 of the wire harness terminal part 6 in the device is accurate each time during processing, providing a unified benchmark for subsequent processing operations.

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

[0053] Step 3: Glue injection operation: The lifting frame 703 drives the top die part 7 to descend, so that the top die part 7 is engaged with the bottom die part 2. At this time, the wire harness wires 602 are completely clamped between the lower wire notch 201 and the upper wire notch 701. Then, the relevant equipment for glue supply 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 the accurate injection amount of the waterproof glue to ensure the quality of the subsequent waterproof sealing structure.

[0054] Step 4: Compaction operation: According to the parameters of the mold cavity 202, the length of the frame-shaped protrusion 605, the taper groove 603, and the trapezoidal groove 604, the motor 8 drives the bottom die part 2 to move towards the limiting plate 101. When the moving distance reaches the preset distance ΔL, it stops. During this process, under the action of pressure, the waterproof glue can fully fill structures such as the trapezoidal groove 604 and the inner peripheral notch 6051, ensuring that the waterproof glue is in close contact with each part of the wire harness terminal part 6 and further improving the waterproof sealing effect.

[0055] Step 5: Product removal: After the glue injection and compaction operations are completed, it is left standing for a preset time t to allow the waterproof glue to fully cure. Then, the lifting frame 703 drives the top die part 7 to rise and return to the initial position before glue injection, and the processed wire harness terminal part 6 is taken out by means of 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: The motor 8 drives the bottom die part 2 to move in the reverse direction to the initial position, preparing for the next processing operation. This step ensures that the processing device can quickly enter the next round of processing process and improves production efficiency.

[0057] Step 7: Circular processing: Repeat the operation contents of Step 2 to Step 6 to realize the continuous processing of multiple wire harness terminal parts 6, so as to meet the production requirements.

[0058] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
