Description

Technical Field

[0001] This utility model belongs to the field of battery pack wiring harness processing technology, specifically relating to a double-head terminal crimping machine for battery pack wiring harnesses. Background Technology

[0002] With the rapid development of new energy vehicles and the energy storage industry, the demand for battery packs is increasing daily. The processing efficiency and precision of battery pack wiring harnesses have become key factors in improving productivity. Traditional battery pack wiring harness processing typically relies on manual operation, which is not only inefficient but also prone to producing defective products, increasing production costs. Therefore, highly automated battery pack wiring harness termination machines with high processing precision have become an inevitable trend in the industry.

[0003] In existing technologies, double-headed cable termination machines are a common type of automated processing equipment. For battery pack wiring harnesses, these machines are primarily used to cut and terminate the wires to ensure processing quality and efficiency. During the processing of battery pack wiring harnesses using a double-headed termination machine, the process typically involves sequentially passing through a length-fixing station, a wire-cutting station, a termination station, a shaping station, and an inspection station. However, traditional double-headed cable termination machines still have certain limitations. For example, they cannot automate the termination, shaping, and inspection of the wiring harness at both ends, and the efficiency of station transfers and switching is low, affecting overall production efficiency.

[0004] To address this, we propose a dual-head wiring terminal machine that can automatically transfer, position, and process dual-head wiring harnesses in battery packs, significantly reducing manual operations and improving efficiency. Utility Model Content

[0005] The present invention aims to solve the technical problem in the prior art that the two ends of the wire harness cannot be automatically and conveniently transferred and switched between the terminal crimping, shaping and inspection stations.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A double-head terminal crimping machine for battery pack wiring harnesses includes a double-head wiring terminal crimping machine, which is equipped with a loading and unloading mechanism for transferring and switching the double-head wiring harness of the battery pack between various workstations.

[0008] The loading and unloading mechanism includes an electric rotary table, a U-shaped seat on the rotating disc of the electric rotary table, a clamping lever cylinder installed in the U-shaped seat, a fixed clamping plate that works with the movable clamping plate on the clamping lever cylinder to clamp and position the double-headed wire harness of the battery pack, and a three-axis linear module that drives the electric rotary table to move in three directions.

[0009] The three-axis linear module moves the battery pack double-headed wire harness to different work stations. The electric rotary table moves the battery pack double-headed wire harness to change the wire end direction or flip it for unloading, so as to realize the automated processing of the battery pack double-headed wire harness by the double-headed wire terminal machine in conjunction with the loading and unloading mechanism.

[0010] The wire end direction conversion enables the terminal crimping, shaping, and inspection of the double-ended wire harness in the battery pack, and drives the double-ended wire harness to rotate, facilitating the unloading of the processed double-ended wire harness to the unloading station. The double-ended wire crimping machine is the main processing equipment, responsible for performing terminal crimping, shaping, and inspection of the double-ended wire harness in the battery pack. The three-axis linear module drives the electric rotary table to move in three directions, moving the double-ended wire harness in the battery pack into different working stations. The rotation of the electric rotary table enables the conversion of the wire end direction of the double-ended wire harness in the battery pack, making it suitable for different processing requirements.

[0011] Preferably, the three-axis linear module includes a Y-axis lead screw linear module, an X-axis lead screw linear module fixed on the longitudinal moving seat of the Y-axis lead screw linear module, and a Z-axis lead screw linear module fixed on the transverse moving seat of the X-axis lead screw linear module.

[0012] Preferably, the electric rotary table is mounted on the lifting frame, and the lifting frame is fixed on the lifting moving seat of the Z-axis lead screw linear module.

[0013] The Y-axis, X-axis, and Z-axis lead screw linear modules allow for precise movement and positioning of the dual-head wiring harness of the battery pack in three-dimensional space, ensuring processing accuracy.

[0014] Preferably, a rotary motor that drives the electric rotary table to rotate is fixed on the lifting frame, and both the electric rotary table and the rotary motor are placed horizontally.

[0015] Preferably, the clamping lever cylinder is fixed on the mounting platform inside the U-shaped seat, and the piston rod end of the clamping lever cylinder passes through the mounting platform and is rotatably connected to the U-shaped groove on the U-shaped block above the mounting platform.

[0016] A support plate is provided on one side of the mounting platform. Two vertical plates on the top of the support plate are rotatably connected to connecting rods. The end of the connecting rod away from the vertical plate is rotatably connected to a U-shaped block. A clamping lever cylinder is fixed on the mounting platform inside the U-shaped seat, which can provide stable support and clamping force to ensure that the battery pack double-ended wiring harness will not shift during processing.

[0017] Preferably, the movable clamp is fixed to the end of the U-shaped block, and the fixed clamp is fixed to the U-shaped seat.

[0018] The clamping slots, which are evenly spaced on both the movable and fixed clamping plates, can precisely align with the dual-head wire harness of the battery pack, ensuring its correct position during processing.

[0019] Preferably, the movable clamping plate and the fixed clamping plate are symmetrically arranged with clamping slots at equal intervals to accommodate the double-headed wire harness of the battery pack, and the inner surface of the clamping slots is bonded with rubber pads.

[0020] The design of the clamping groove and the bonding of the rubber pad provide greater friction, enhancing the clamping force on the dual-headed wiring harness of the battery pack and preventing slippage during processing.

[0021] Compared with the prior art, the technical effects and advantages of this utility model are:

[0022] This dual-head terminal crimping machine for battery pack wiring harnesses uses a three-axis linear module to precisely move and position the dual-head wiring harnesses. Combined with the movement of an electric rotary table, it achieves the reversal and flipping of the wire ends for unloading. Specifically, the Y-axis, X-axis, and Z-axis lead screw linear modules work together to drive the electric rotary table and its U-shaped support and clamping lever cylinders, allowing the wiring harness to move accurately to various workstations in three-dimensional space. The rotation of the electric rotary table changes the orientation of the wiring harness to adapt to different processing requirements. This automated processing capability significantly improves production efficiency, reduces manual operation, and lowers safety risks during production. The precise control of the three-axis linear module and clamping mechanism ensures processing accuracy, effectively reducing the generation of defective products and thus saving production costs. Furthermore, automated processing reduces the number of workers and labor costs, optimizing the production process.

[0023] The ability to change and flip the wire end direction increases the flexibility of processing dual-ended wire harnesses for battery packs, enabling the equipment to adapt to different types and specifications of wire harnesses. The design of the clamping grooves and the bonding of the rubber pads enhance clamping force, ensuring the stability and safety of the wire harness during processing, reducing wear from direct contact between the wire harness and the clamping plate, and extending the equipment's lifespan. Overall, this automated processing solution not only improves processing quality but also optimizes equipment operation and maintenance, increasing production efficiency. Attached Figure Description

Detailed Implementation

[0029] 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.

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] This application discloses a double-head terminal crimping machine for battery pack wiring harnesses, including a double-head wiring terminal crimping machine, which is equipped with a loading and unloading mechanism for transferring and switching the double-head wiring harness of the battery pack between various workstations.

[0032] The loading and unloading mechanism includes an electric rotary table 1, a U-shaped seat 3 on a rotating disc 2 on the electric rotary table 1, a clamping lever cylinder 4 installed in the U-shaped seat 3, a fixed clamping plate 6 that works with the movable clamping plate 5 on the clamping lever cylinder 4 to clamp and position the double-headed wire harness of the battery pack, and a three-axis linear module 7 that drives the electric rotary table 1 to move in three directions.

[0033] The three-axis linear module 7 includes a Y-axis lead screw linear module 71, an X-axis lead screw linear module 73 fixed on a longitudinal moving seat 72 of the Y-axis lead screw linear module 71, and a Z-axis lead screw linear module 75 fixed on a transverse moving seat 74 of the X-axis lead screw linear module 73. An electric rotary table 1 is rotatably mounted on a lifting frame 8, which is fixedly mounted on a lifting moving seat 76 of the Z-axis lead screw linear module 75. A rotary motor 9, which drives the electric rotary table 1 to rotate, is fixedly mounted on the lifting frame 8. Both the electric rotary table 1 and the rotary motor 9 are horizontally positioned.

[0034] The Y-axis, X-axis, and Z-axis lead screw linear modules allow for precise movement and positioning of the battery pack double-ended wiring harness in three-dimensional space, ensuring processing accuracy. The three-axis module allows for adjustment of the wiring harness position in three-dimensional space; movement in three directions expands the processing range and accommodates battery pack double-ended wiring harnesses of different lengths and specifications. The horizontally positioned electric rotary table 1 and rotary motor 9 provide more stable support and rotation due to gravity, reducing vibrations that may occur during processing. The horizontal design makes more efficient use of space, especially vertical space, thus reducing the equipment's footprint. The horizontal placement also makes maintenance and operation of the rotary motor 9 and electric rotary table 1 more convenient, as their position is closer to the operator and facilitates visual inspection.

[0035] The clamping lever cylinder 4 is fixed on the mounting platform 10 inside the U-shaped seat 3. The piston rod end of the clamping lever cylinder 4 passes through the mounting platform 10 and is rotatably connected to the U-shaped groove 12 on the U-shaped block 11 above the mounting platform 10.

[0036] A support plate 13 is provided on one side of the mounting platform 10. Connecting rods 15 are rotatably connected to two upright plates 14 at the top of the support plate 13. The end of the connecting rod 15 away from the upright plate 14 is rotatably connected to a U-shaped block 11. A clamping lever cylinder 4 is fixed to the mounting platform 10 inside the U-shaped seat 3, providing stable support and clamping force to ensure that the battery pack's dual-head wiring harness does not shift during processing. The rotatable connection between the piston rod end and the U-shaped block 11 makes the clamping action faster and more accurate, improving production efficiency.

[0037] The movable clamp 5 is fixed to the end of the U-shaped block 11, and the fixed clamp 6 is fixed to the U-shaped seat 3.

[0038] The movable clamping plate 5 and the fixed clamping plate 6 have equally spaced clamping slots 16 that can accurately align the dual-head wire harness of the battery pack, ensuring its correct position during processing. The movable clamping plate 5 and the fixed clamping plate 6 have equally spaced symmetrically arranged clamping slots 16 that are designed to accommodate the dual-head wire harness of the battery pack. The inner surface of the clamping slots 16 is bonded with rubber pads 17.

[0039] The design of the clamping groove 16 and the bonding of the rubber pad 17 provide greater friction, enhancing the clamping force on the dual-ended wiring harness of the battery pack and preventing slippage during processing. The rubber pad 17 on the inner surface of the clamping groove 16 reduces wear caused by direct contact between the wiring harness and the clamping plate, protecting the surface of the wiring harness. The rubber pad 17 provides a certain degree of elasticity and cushioning, making the clamping more stable and preventing easy loosening even under vibration or impact.

[0040] The three-axis linear module 7 drives the battery pack double-headed wire harness to different working positions. The electric rotary table 1 drives the battery pack double-headed wire harness to change the wire head direction or flip it for unloading, so as to realize the automated processing of the battery pack double-headed wire harness by the double-headed wire terminal machine in conjunction with the loading and unloading mechanism.

[0041] The wire head direction conversion enables the terminal crimping, shaping and inspection of the double-ended wire harness of the battery pack, and drives the double-ended wire harness of the battery pack to flip, making it convenient to unload the processed double-ended wire harness of the battery pack to the unloading station;

[0042] The double-ended wiring harness terminal crimping machine is the main processing equipment, responsible for crimping, shaping, and inspecting the double-ended wiring harness of the battery pack.

[0043] The U-shaped base 3 is fixed on the rotating disk 2 of the electric rotary table 1 and can rotate with the electric rotary table 1 to change the direction of the battery pack's double-ended wiring harness. A clamping lever cylinder 4 is installed inside the U-shaped base 3, and clamps the battery pack's double-ended wiring harness by extending and retracting the cylinder, ensuring it remains fixed during processing. The fixed clamping plate 6 cooperates with the movable clamping plate 5 to clamp and position the battery pack's double-ended wiring harness. The three-axis linear module 7 drives the electric rotary table 1 to move in three axes, moving the battery pack's double-ended wiring harness into different working positions. The rotation of the electric rotary table 1 allows for the reversal of the wire end direction of the battery pack's double-ended wiring harness, making it suitable for different processing requirements.

[0044] Automated processing reduces manual labor and improves production efficiency. Precise control via the three-axis linear module 7 and clamping mechanism ensures the accuracy of battery pack double-ended wiring harness processing, reducing defective products. The wire end direction conversion and flipping function makes the processing of battery pack double-ended wiring harnesses more flexible, suitable for different types and specifications of wiring harnesses. Automated processing reduces the number of workers and lowers labor costs. Automated equipment reduces the complexity of manual operation and lowers safety risks in the production process. Rapid transfer and switching of workstations, along with automated processing, significantly improves production efficiency.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
