Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field, and in particular relates to an automatic laser marking device for wiring harnesses of new energy vehicles. Background Art
[0002] Automotive wiring harnesses are a core component of a vehicle's electrical system, consisting of wires, connectors, and protective tubing. They transmit power and signals. Laser marking uses a high-energy laser beam to imprint information on the wiring harness surface, replacing traditional ink printing or labeling. It offers high efficiency, precision, and durability.
[0003] In the prior art, automotive wiring harnesses are generally marked using automatic laser marking equipment. However, in actual use, the above equipment still has the following problems:
[0004] 1. Since wire harness processing is a continuous process, the wire harness undergoes multiple processing steps after hot melt extrusion to form a finished wire harness. Laser marking is an intermediate link. Therefore, components for transporting the wire harness are required before and after the process. However, when using the above-mentioned transport components, due to the flexibility and ductility of the wire harness itself, part of the wire harness will be twisted during transportation. This will cause the mark that appears to be in the same direction to be distorted and tilted when it returns to its original state after the wire harness is processed. This is not only unsightly, but also affects the content of the mark.
[0005] 2. In wire harness processing, the wire harness often has a long process and operation. Therefore, before laser marking, solid or liquid adhesion may occur on the outer surface of the wire harness, thus affecting the laser marking effect.
[0006] Based on the above problems, the present invention designs an automatic laser marking device for new energy vehicle wiring harnesses. Summary of the Invention
[0007] The purpose of the present invention is to solve the problems in the prior art and to propose an automatic laser marking device for new energy vehicle wiring harnesses.
[0008] In view of the above problems, the purpose of the present invention is to provide an automatic laser marking device for new energy vehicle wiring harnesses.

The fixed platform is located below the laser marking component and is movably connected to the two guide platforms. Two sets of transmission pulley parts are rotatably connected to each guide platform, and the two sets of transmission pulley parts are located on both sides of the wiring harness. Each set of transmission pulley parts includes two synchronous wheels, and the two synchronous wheels are connected by a synchronous belt. Both synchronous wheels are rotatably connected to the guide platform through a rotating shaft. The bottom of one of the rotating shafts is connected to a rotating motor, and the two synchronous belts abut against both sides of the wiring harness. The synchronous belts are connected to a sensor for detecting the torsion state of the wiring harness.
[0017] In the above-mentioned automatic laser marking equipment for new energy vehicle wiring harnesses, the guide platform and the fixed platform have the same cross-section and cooperate with the inside of the cylindrical shell. A connecting block is provided at the bottom of each guide platform close to the fixed platform, and both side end surfaces of the fixed platform are provided with annular grooves that cooperate with the connecting block.
[0018] In the above-mentioned automatic laser marking equipment for new energy vehicle wiring harnesses, the rotating part includes a half-toothed ring arranged on the outside of two guide platforms, and the two half-toothed rings are respectively engaged with adjustment gear 1 and adjustment gear 2. The adjustment gear 1 and adjustment gear 2 are respectively connected to the base plate through mounting seats. The adjustment gear 1 and adjustment gear 2 are coaxially arranged and jointly connected to the sorting part, and the sorting part includes a drive motor for driving the adjustment gear 1 and adjustment gear 2 to rotate simultaneously.
[0019] In the above-mentioned automatic laser marking equipment for new energy vehicle wiring harnesses, the arranging part includes a differential adjustment part and a reversing part for switching the speed difference between adjustment gear 1 and adjustment gear 2. The differential adjustment part includes a friction disc 1 connected to the drive motor, and a friction disc 2 is connected to each side of the friction disc 1. The friction disc 1 and the friction disc 2 are respectively matched with the adjustment gear 1 and the adjustment gear 2 through a fixed rod group and a telescopic rod group.
[0020] In the above-mentioned automatic laser marking equipment for new energy vehicle wiring harnesses, the reversing part includes bevel gear 1, which is connected to the end of the fixed rod group, and is meshed with bevel gear 2. The opposite side of bevel gear 2 is meshed with bevel gear 3 with the same specifications as bevel gear 1. Bevel gear 2 is connected to the connecting seat through a connecting shaft, and bevel gear 3 is connected to the adjustment gear 1 through a fixed shaft.
[0021] In the above-mentioned automatic laser marking equipment for new energy vehicle wiring harnesses, the outer sides of the friction disc 1 and the friction disc are both connected with connecting sleeves, and the two connecting sleeves are commonly connected with a positioning rod, which passes through the telescopic rod group and the correspondingly connected friction disc 2 and connecting sleeve.
[0022] In the above-mentioned automatic laser marking equipment for new energy vehicle wiring harnesses, the cleaning part includes a cavity opened in the guide platform, the drive motor is arranged in the cavity, and the upper part of the guide platform is symmetrically provided with two raised parts. The cavity is located at the raised part and is provided with multiple drainage ports. The multiple drainage ports are facing the synchronous belt. Each of the cavities is connected to a connecting pipe, and the connecting pipe is installed on the end cover. A negative pressure machine is provided in the cavity, and the negative pressure machine sucks external gas into the cavity.
[0023] In the above-mentioned automatic laser marking equipment for new energy vehicle wiring harnesses, a vertical cylinder is inserted into the two synchronous belts in each group of the guide conveying components. The two vertical cylinders are arranged opposite each other and both compress the synchronous belts to a recessed state. An air jet facing the wiring harness is opened in the vertical cylinder, and the bottom of the vertical cylinder is connected to the cavity.
[0024] The beneficial effects of the present invention are as follows: through VMD decomposition, the original rainfall sequence is broken down into multiple sub-components with different frequencies and characteristics, making the temporal characteristics of each component clearer, thereby improving the accuracy of the overall prediction. At the same time, LSTM, with its powerful nonlinear modeling capabilities and ability to capture long-term and short-term dependencies, can fully exploit the dynamic characteristics of the signal when combined with the decomposed sub-sequences, further enhancing the prediction effect. In addition, particle swarm optimization (PSO) automatically optimizes LSTM hyperparameters through global search, which not only reduces the workload of manual parameter adjustment, but also effectively avoids the impact of suboptimal parameters on model performance, enabling the model to achieve better prediction performance.
