Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of multi-core wire terminal crimping and rubber shell inserting, and particularly relates to a multi-core wire single-side rubber shell inserting machine. BACKGROUND

[0002] An automobile wire harness is usually composed of multi-core wire, metal terminal for electrical connection, rubber shell for protecting and positioning the terminal, and the like. The multi-core wire is generally stored in a roll, the terminal is usually supplied in a continuous roll in the form of a terminal tape, and the rubber shell is usually a small and discrete structure. When manufacturing the wire harness, the roll-shaped multi-core wire needs to be straightened first, and then cut according to a set length. Then, the terminal end of the wire to be connected is stripped to expose the core wire segment suitable for crimping. After stripping, the terminal needs to be crimped on the core wire end to form a terminal assembly that can be inserted into the rubber shell. Then, the core wire end with the terminal is inserted into the inner cavity of the corresponding rubber shell to complete the assembly of the wire harness end structure.

[0003] However, the multi-core wire in the automobile wire harness often contains multiple thin core wires, each of which has a small diameter. It is difficult to accurately position the core wire during the stripping, transferring, crimping and rubber shell inserting processes. Meanwhile, the rubber shell usually has multiple rows and distinguishing features of front and back surfaces. The existing rubber shell equipment is mostly single-structured and can only adapt to specific processes or specific types of rubber shell structures. The existing rubber shell equipment cannot adjust the direction of the core wire or transfer the core wire in sections, resulting in low consistency of finished products, high rubber shell defect rate, and thus low production efficiency and cost waste. SUMMARY

[0004] In order to improve the defects of inaccurate positioning of the multi-core wire during processing and rubber shell inserting, automatic direction adjustment and smooth connection during transferring, which result in high rubber shell defect rate and low production efficiency, the present application provides a multi-core wire single-side rubber shell inserting machine.

[0005] The multi-core wire single-side rubber shell inserting machine provided by the present application adopts the following technical scheme: A multi-core wire single-side rubber shell inserting machine, comprising a rack, a core wire feeding device arranged on the rack, a core wire straightening device connected with the rack and located on one side of the core wire feeding device, a core wire cutting device connected with the rack and located on one side of the core wire straightening device, a terminal feeding device connected with the rack, a terminal crimping device arranged on the rack and used for crimping the terminal and the core wire, a rubber shell feeding device connected with the rack, a wire storage device, a core wire direction adjusting device connected with the rack, a core wire transferring device, and a core wire inserting device used for inserting the crimped core wire into the rubber shell; the wire storage device is located between the terminal crimping device and the core wire direction adjusting device.

When the rubber plug shell moves from the rubber plug shell guide channel to the transverse guide mechanism, the rubber plug shell pushing mechanism is used for pushing the rubber plug shell from the transverse guide mechanism to the rubber plug shell limiting seat in the transverse direction.

[0016] By adopting the above technical solution, the material guide channel allows the insert shell to slide into the transverse material guide mechanism in a stable posture. The transverse material guide mechanism serves as a temporary buffer and guide rail, reserving lateral movement space for subsequent pushing actions. The insert shell pushing mechanism is located at one end of the transverse material guide mechanism. After the insert shell is in place, it pushes the foremost insert shell laterally to the insert shell limiting seat at the other end of the transverse material guide mechanism, accurately positioning it in the insertion position. This device achieves full automation of the insert shell process from bulk feeding to precise positioning through a coordinated mechanism of vibration sorting, directional conveying, transverse buffering, and active pushing.

Then, the core wire is released to enter the subsequent insertion process. Through the above structure, this application can automatically adjust the direction of the core wire according to the different front and back sides, top and bottom rows or multi-layer structures of the insert housing, effectively avoiding terminal deformation, insertion failure or poor contact caused by mismatched posture, and significantly improving the adaptability and success rate of the core wire insert housing. At the same time, the reversing device has a compact structure and precise and reliable operation, which can meet the flexible requirements of multi-specification insert housing mixed wire production, and is a key mechanism to improve the overall insertion quality and automation level.

Through the array cooperation of the multiple clamps and the lifting module, the application realizes the temporary storage, buffering and sequencing management of the core wire, effectively solves the problems of waiting, misalignment and attitude drift of multiple core wires under different beats, improves the flexibility, beat stability and assembly consistency of the whole machine, avoids insertion errors and processing defects caused by core wire suspension or bending, and significantly enhances the overall automation level and product reliability.

The core wire transverse movement mechanism is a common rail driving platform, so that multiple transfer mechanisms can run on the same rail, realizing multi-station flexible flow with compact structure, fast station switching and unified action rhythm, effectively avoiding the problems of large size, long path and slow response of traditional mechanical arm structure.
