Technical Field

[0001] The invention relates to the technical field of optoelectronic stand-alone product assembly, and in particular to a wire automatic preprocessing system and method, which are used for automatic preprocessing of wires of different specifications. Background Art

[0002] Pre-processing processes such as wire cutting, labeling, and wire tying are necessary tasks for preparing for the assembly and production of optoelectronic stand-alone products, such as fiber optic gyroscopes and inertial groups. They are usually completed manually, which is inefficient. In order to avoid subsequent errors caused by incorrect wire number labeling, one person is required to operate and one person is required to check each other, which also wastes manpower. Current automatic wire processing equipment generally processes a single wire and cannot achieve complete set pre-processing according to a single set of products. That is, the wires that have been automatically labeled still need to be manually sorted and matched according to the needs of a single set of products; or they can only automatically process the wires of a set of products at a time, so the machine must be paused, the wires of a single set of products must be removed, and then the wire pre-processing of all sets of products must be performed in this way. The entire process basically cannot be done without human assistance and also requires manpower.

[0003] At present, there is no wire pre-processing equipment that can automatically process multiple sets of products at one time. Summary of the invention

After a single set of wires are bundled, the bin flipping mechanism drives the wire bundling bin to flip 180 degrees, rushes down to release the processed wire bundle, and the wire bundle falls into the finished product box. The bin flipping mechanism then drives the wire bundling bin back to the standby position;

[0056] S12, repeating steps S3 to S11 until the labeling and wiring binding operations of all sets of wire harnesses set in the wire automatic preprocessing upper computer software in S2 are completed.
