Description

Technical Field

[0001] The present invention relates to the technical field of wire harness processing, and specifically to a multi-strand wire inserting end device and method. Background Art

[0002] In the wire harness industry, the insertion of stranded wires and single wires is a common process. With the continuous increase of labor costs, the main engine manufacturers have higher and higher requirements for the quality of wire harnesses, and the proportion of stranded wire insertion is also increasing. Automobile wire harness manufacturers urgently need a highly automated and versatile fully automated production and processing solution for such processes. This new fully automated processing mode will bring greater competitive advantages to automobile manufacturers.

[0003] Currently, the known methods for inserting and processing stranded wires and single wires in the wire harness industry are as follows: The stranded wires are taken off the production line through a stranded wire processing center, and then manually arranged on a tray. The equipment transports the stranded wires to the inserting end process through a carrier tray and automatically completes the insertion. The single wires are automatically completed by the equipment from the incoming material of the barrel-shaped wire. After the product processing is completed, it is removed manually. This known mode has relatively large limitations.

[0004] Disadvantage 1: There are many turnover materials. One stranded wire processing center cannot process multiple types of stranded wires at the same time. It is necessary to change the type and process them in sequence after processing one type.

[0005] Disadvantage 2: In the manual tray arrangement mode, it is easy to make mistakes and there is no anti-fooling function. If the wire colors of multiple stranded wires are the same but the wire lengths are different, it is impossible to effectively identify and prevent errors. It is easy to cause incorrect insertion circuits and it is impossible to effectively judge whether they will flow to the subsequent processes or even customers, resulting in relatively large quality risks. If the wire colors of multiple stranded wires are the same and the differences in terminals are small, it is impossible to effectively identify and prevent errors, which is easy to cause poor insertion and additional scrapping, affecting production efficiency.

[0006] Disadvantage 3: The processing modules for single wires and stranded wires with the same terminals and waterproof plugs cannot be shared, resulting in high costs.

[0007] Therefore, we propose a multi-strand wire inserting end device and method to facilitate solving the problems raised above. Summary of the Invention

[0008] The object of the present invention is to solve the problems existing in the current plug-in processing method of stranded wires and single wires in the wire harness industry. There are many turnover materials, and a stranded wire processing center cannot process multiple types of stranded wires simultaneously. After processing one type, it is necessary to change the model for processing in sequence, and it requires a manual palletizing mode, which is prone to errors and cannot prevent mistakes. There is no difference in the wire colors of multiple stranded wires, but the wire lengths are different, so effective identification and error prevention cannot be carried out, which easily causes errors in the plug-in circuit and cannot be effectively judged, and it will flow to the subsequent processes or even customers, resulting in relatively large quality risks. There is no difference in the wire colors of multiple stranded wires, and the difference in terminals is small, so effective identification and error prevention cannot be carried out, which easily causes poor plug-in and additional scrap, affecting production efficiency. Moreover, the processing of single wires and stranded wires with the same terminals and waterproof plugs cannot share processing modules, resulting in high costs.

[0009] To achieve the above object, the present invention adopts the following technical solutions: A device and method for inserting terminals of multiple stranded wires, including: a frame, on which a lifting wire rack is arranged;

[0010] A stranded wire straightening mechanism, arranged on the frame, for straightening the stranded wires to be stranded on the lifting wire rack;

[0011] A wire pulling mechanism, arranged on the frame, for feeding the straightened stranded wires to be stranded at a fixed length;

[0012] A stranded wire cutting mechanism, arranged on the mechanism frame, for cutting the stranded wires to be stranded that are fed at a fixed length;

[0013] A waterproof plug workstation and a waterproof plug pressing and handling mechanism, arranged on the frame. The waterproof plug workstation includes a waterproof plug component, and the waterproof plug of the wire harness is inserted through the cooperation of the waterproof plug component and the waterproof plug pressing and handling mechanism;

[0014] A terminal insertion workstation, arranged at the end of the frame, for inserting the terminals of the wire harness through the terminal insertion workstation.

[0015] Further, the waterproof plug workstation further includes a skeleton, on which a material extraction cylinder component, a feeding guide rail, a vibration component, a material taking frame component, and a detection component are arranged. The waterproof plug component is arranged on the skeleton. The waterproof plug material is extracted to the feeding guide rail through the material extraction cylinder component. The vibration component makes the waterproof plug material on the feeding guide rail move forward through vibration for feeding. The material taking frame component takes out the waterproof plugs on the feeding guide rail and transfers them to the waterproof plug component, and the waterproof plug is inserted through the cooperation of the waterproof plug component and the waterproof plug pressing and handling mechanism.

[0016] Further, the terminal insertion workstation includes a three-moving-sub straight line module, and a wire harness fixed-distance handling mechanism, a left terminal inserting shell module, and a right terminal inserting shell module are suspended on the three-moving-sub straight line module.

[0017] Further, a peeling handling mechanism and a peeling mechanism are arranged on the frame, and the wire harness is peeled through the cooperation of the peeling handling mechanism and the peeling mechanism.

[0018] Further, an unwinding and transfer mechanism is provided on the frame to unwind and relieve the tension of the wire harness by rotating it through the unwinding and transfer mechanism.

[0019] Further, a core wire vision inspection mechanism and a crimping appearance vision inspection mechanism for detection are provided on the frame.

[0020] Further, a terminal crimping machine and a crimping transfer mechanism are provided on the frame.

[0021] Further, a terminal turning mechanism is provided on the frame near the plug-in end workstation.

[0022] An insertion method for a multi-strand wire plug-in end device based on the above-mentioned device includes the following steps:

[0023] S1: Select the wire harness entering the lifting wire rack through the lifting wire rack. After straightening, perform fixed-length wire feeding and cutting. When the wire harness is a stranded wire, twist it.

[0024] S2: Use the peeling and handling mechanism to transport the wire harness to the peeling mechanism for peeling. After peeling, transfer it to the unwinding and transfer mechanism. The bolt-passing and crimping handling mechanism grabs the wire harness from the unwinding and transfer mechanism and transports it to the bolt-passing workstation to complete bolt-passing.

[0025] S3: After bolt-passing, the wire harness is transferred by the bolt-passing and crimping handling mechanism to the core wire vision inspection mechanism for inspection. The bolt-passing and crimping handling mechanism grabs the wire harness from the core wire vision inspection and then transports it to the terminal crimping machine to complete terminal crimping. Then it is transferred to the crimping transfer mechanism. The bolt-passing and crimping handling mechanism grabs the wire harness from the crimping transfer mechanism and then transports it for subsequent crimping and crimping appearance vision inspection. After completion, it is transported to the terminal turning mechanism.

[0026] S4: Use the wire harness fixed-distance handling mechanism of the plug-in end workstation to transport the wire harness at the terminal turning mechanism, and use the left terminal inserting shell module and the right terminal inserting shell module to grab the wire harness to perform the plug-in end work.

[0027] The beneficial effects of the present invention: By providing a stranded wire straightening mechanism, a wire pulling mechanism, and a stranded wire cutting mechanism on the frame, it is possible to realize the mixed processing and plugging of various stranded wires and various single wires through the stranded wire straightening mechanism and the wire pulling mechanism, without the need for tool change processing and manual participation in the tray arrangement operation, greatly reducing the occurrence of errors. Through the setting of the bolt-passing workstation and the plug-in end workstation, the processing of single wires and stranded wires with the same terminal and waterproof bolt can share the processing module, reducing costs.
