Description

Technical Field

[0001] This utility model belongs to the field of wire harness welding technology, specifically relating to a wire harness welding and cutting mechanism and a wire harness welding machine. Background Technology

[0002] Ultrasonic welding utilizes high-frequency vibration waves transmitted to the surfaces of two objects to be welded. Under pressure, the surfaces rub against each other, causing fusion between molecular layers. When welding wire harnesses using a wire harness welding machine, the wire harness connection end needs to be placed on the welding station, then fixed by a fixing component, and finally welded by the wire harness welding machine.

[0003] The existing cutting device has the following technical problems: on the one hand, the cutting device is installed at the bottom, and the cylinder, cylinder connecting rod and cutting blade run through the entire welding machine head. The welding machine structure needs to be designed to make way for it, which makes the originally compact machine head structure weak; on the other hand, the cutting device is installed at the bottom, and the entire welding machine head is high at the tail, which is not convenient for installation, debugging and maintenance.

[0004] Therefore, it is necessary to improve upon the shortcomings of existing technologies in order to overcome their deficiencies in practical applications. Utility Model Content

In other words, one of the objectives of this utility model is to provide a wire harness welding and cutting mechanism and a wire harness welding machine that meet one or more of the aforementioned requirements.

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

[0007] This utility model provides a wire harness welding and cutting mechanism, including a fixed base, a drive unit, a transmission assembly, and a cutting blade. The transmission assembly is installed in the fixed base. The transmission assembly includes a first rack, a gear, and a second rack. The drive unit is connected to the first rack, the first rack is driven by the gear, the gear is driven by the second rack, and the second rack is connected to the cutting blade. The drive unit drives the first rack to move laterally, the first rack rotates in conjunction with the gear, and the gear moves the second rack up and down, so that the second rack moves the cutting blade up and down.

[0008] As a preferred embodiment, a gear is installed inside the fixed base, and the gear is rotatably connected to the fixed base.

[0009] As a preferred embodiment, the gear is configured with a first meshing tooth and a second meshing tooth, wherein the first meshing tooth is connected to the first rack in a driving connection, and the second meshing tooth is connected to the second rack in a driving connection.

[0010] As a preferred embodiment, the first rack and the second rack are arranged perpendicularly.

[0011] As a preferred embodiment, the drive unit is configured as a cylinder.

[0012] As a preferred embodiment, the drive unit and the first rack are arranged in a horizontal direction.

[0013] This utility model also provides a wire harness welding machine, including an ultrasonic welding assembly and a cutting mechanism as described in any of the above embodiments. The ultrasonic welding assembly is used to weld wire harnesses, and the cutting mechanism is used to cut abnormal wire harnesses.

[0014] Compared with the prior art, the advantages of this utility model are:

[0015] The wire harness welding and cutting mechanism provided by this utility model avoids the problem of weak machine head structure caused by traditional bottom installation method by optimizing the structural layout.

[0021] To more clearly illustrate the embodiments of this application, the specific implementation methods of this application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0022] In the description of the embodiments of this application, the terms "upper," "lower," "front," "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. In addition, the terms "first," "second," etc., are only used for distinction in description and have no special meaning.

[0023] According to some embodiments of this application, please refer to Figures 1 to 2 As shown, a wire harness welding and cutting mechanism is provided, including a fixed base 1, a drive unit 2, a transmission assembly 3, and a cutting blade 4. The transmission assembly 3 is installed in the fixed base 1. The transmission assembly 3 includes a first rack 31, a gear 32, and a second rack 33. The drive unit 2 is connected to the first rack 31, the first rack 31 is driven by the gear 32, the gear 32 is driven by the second rack 33, and the second rack 33 is connected to the cutting blade 4. The drive unit 2 drives the first rack 31 to move laterally, the first rack 31 drives the gear 32 to rotate, and the gear 32 drives the second rack 33 to move up and down, so that the second rack 33 drives the cutting blade 4 to move up and down.

[0024] In some embodiments of this application, the drive unit 2 uses a cylinder as a power source. The piston rod of the cylinder is fixedly connected to one end of the first rack 31. When the piston rod of the cylinder makes a lateral extension and retraction movement, it will drive the first rack 31 to move laterally in sync.

[0025] In some embodiments of this application, the drive unit 2 and the first rack 31 are arranged horizontally, and the first rack 31 and the second rack 33 are arranged perpendicularly. This vertical transmission design allows the lateral movement of the drive unit 2 to be efficiently converted into the longitudinal cutting action of the cutting blade 4. When the second rack 33 moves up and down, it drives the cutting blade 4 connected to it to move up and down synchronously, thereby realizing the cutting operation of the wire harness. In practical applications, the motion parameters of the drive unit 2 can be adjusted according to the specifications of the wire harness and the cutting requirements to control the cutting force and speed of the cutting blade 4.

[0026] In some embodiments of this application, the gear 32 is configured with a first meshing tooth 321 and a second meshing tooth 322. The first meshing tooth 321 is drivenly connected to the first rack 31, and the second meshing tooth 322 is drivenly connected to the second rack 33.

[0027] Specifically, the first rack 31 is provided with a tooth groove that matches the first meshing tooth 321 of the gear 32. The two mesh with each other for transmission. When the first rack 31 moves laterally, it drives the gear 32 to rotate around its central axis. When the gear 32 rotates, its second meshing tooth 322 meshes with the tooth groove on the second rack 33, thereby driving the second rack 33 to move up and down in a linear motion. Since the second rack 33 is fixedly connected to the cutting blade 4, the up and down movement of the second rack 33 is directly transmitted to the cutting blade 4, causing the cutting blade 4 to also move up and down in a linear motion, thus realizing the cutting operation of the wire harness.

[0028] In some embodiments of this application, the fixed base 1 serves as a support component for the entire cutting mechanism. It contains bearings or bushings for mounting the gear 32, ensuring that the gear 32 can rotate smoothly around its central axis while reducing frictional losses. The fixed base 1 also protects the internal transmission assembly 3, preventing external impurities or foreign objects from entering the transmission assembly 3 and affecting its normal transmission.

[0029] In some embodiments of this application, in order to further improve the stability and reliability of the cutting mechanism, a shock-absorbing device or a buffer device may be provided between the fixed base 1 and the transmission assembly 3 to reduce the vibration and impact generated during transmission and extend the service life of the cutting mechanism.

[0030] By optimizing the structural layout, the problem of weak head structure caused by traditional bottom mounting method is avoided. At the same time, the overall height of the machine is reduced, which facilitates installation, debugging and maintenance. The vertical transmission design of gear and double rack is adopted, which can efficiently convert the lateral movement of the drive unit into the longitudinal cutting action of the cutting blade. This not only improves the transmission stability, but also significantly reduces the size of the equipment.

[0031] This application also provides a wire harness welding machine, including an ultrasonic welding assembly 5 and a cutting mechanism as described above. The ultrasonic welding assembly 5 is used to perform welding operations on the wire harness, while the cutting mechanism is used to cut abnormal wire harnesses during or after welding, ensuring welding quality and production efficiency. By integrating the ultrasonic welding assembly and the cutting mechanism, integrated operation of wire harness welding and cutting is achieved, improving the automation level and production efficiency of the production line.

[0032] By forming a collaborative working system with the cutting mechanism and ultrasonic welding components, abnormal wire bundles can be quickly cut during the welding process, thereby ensuring the overall welding quality. The welding machine has a more compact structure, which not only enhances mechanical strength but also optimizes space utilization, providing a convenient operating channel for subsequent maintenance and repair.

[0033] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0034] The above description is only a detailed explanation of the preferred embodiments and principles of this application. For those skilled in the art, there may be changes in the specific implementation methods based on the ideas provided by this utility model, and these changes should also be considered within the scope of protection of this application.
