Description

Technical Field

[0001] The present invention relates to the technical field of optoelectronic stand-alone product assembly, and in particular to an automatic labeling system and method for electric connectors, which are used for automated processing of labeling of electric connectors. Background Art

[0002] In the assembly and production preparation process of optoelectronic stand-alone products, such as fiber optic gyroscopes and inertial groups, labeling of electrical connectors is a necessary operation. Electrical connectors purchased directly from manufacturers generally only have the point number of the electrical connector marked on the plug or socket part. If the built-in wires are labeled, they only indicate the point number information of each wire, that is, the point number of the corresponding point on the plug or socket of the electrical connector to which the wire is connected. When preparing for the assembly and production of optoelectronic stand-alone products, it is necessary to affix labels to the ends of the built-in wires of the electrical connector to indicate the line number information of the connection relationship, that is, to indicate which point of other components in the optoelectronic stand-alone product each wire needs to be connected to, so that the assembly workers can complete the welding and installation of the built-in wires of the electrical connector more quickly in the subsequent assembly according to the line number label information. At present, the labeling of electrical connectors is mainly done manually, requiring one worker to label each wire on the electrical connector according to the wiring diagram information, and another worker to check the correctness of the labeling; there are also semi-automatic electrical connector labeling equipment on the market, which requires one worker to insert the wires of the electrical connector into the equipment one by one for labeling, and the whole process cannot be done without human intervention. At present, there is no fully automatic labeling system for electrical connectors that can achieve batch loading without manual intervention, and the present invention fills this gap.

[0084] The wire pressing plate is an annular disk structure. The hollow structure in the center of the annular ring is a reserved position after the quick clamping mechanism 14 is installed on the disc 11. The wire pressing plate has M mounting holes. The relative positions of the mounting holes correspond to the relative positions of the wire pressing plate guide pillars 12 on the disc 11. The wire pressing plate guide pillars 12 are inserted into the mounting holes to fix the wire pressing plate above the disc 11.

[0085] One end of the electrical connector 110 is a plug, and the other end is a wire harness. The plug passes through the middle hole of the wire pressing plate and docks with one end of the quick clamping mechanism 14. The wires are positioned by the slots on the disc 11 and extend to a distance outside the disc 11.

The product positioning turnover jig loading base 212 is used to stack product positioning turnover jigs 1 in batches at one time. The feeding and lifting servo mechanism 211 moves the topmost product positioning turnover jig 1 placed on the product positioning turnover jig loading base 212 upward to the grabbing position of the jig handling component so that the jig handling component grabs the product positioning turnover jig 1.

[0108] The material unloading station 22 includes a material receiving and lowering servo mechanism 221 and a product positioning and turnover jig unloading base 222. The material receiving and lowering servo mechanism 221 moves downward to lower the product positioning and turnover jig 1 stacked on the product positioning and turnover jig unloading base 222 to a suitable position, so that the jig transport component 24 can stack the electrical connector product positioning and turnover jig 1 that has been labeled on the multi-station rotating platform 32 on the top layer of the product positioning and turnover jig unloading base 222.

[0112] The feeding lifting servo can automatically lift all the placed product positioning and turnover jigs to the workstation rotating platform for subsequent wire testing and labeling operations; the collecting and descending servo can automatically recycle the product positioning and turnover jigs that have completed the labeling operation.

[0113] The present invention can design control software for electrical connector labeling equipment, and use it to control product positioning turnover jigs, conduction test components, labeling modules, label printers, turnover jig handling modules and other mechanisms, and perform wire conduction test, labeling, labeling, transportation and other processes according to the set wire number, etc., to complete the automatic labeling of electrical connectors. An electrical connector is clamped and placed into the tooling at one time, and the software controls the conduction test mechanism to perform a conduction test on the wire and identify the wire number. The labeling system prints the corresponding point number label according to the wire number identification result, and automatically sticks the label near the end of the wire. After all electrical connector wires are labeled, the tooling is automatically pushed out.

[0114] The control software can also set wire and label paper shortage alarms and working status fault alarms to realize the alarm function during the labeling process of electrical connectors. The working status of the equipment is set to be visible, with a display light to prompt the status of normal operation, interruption and fault alarm. The electrical connector labeling software parameter setting can directly import the electrical connector line number from the electronic version of the process file wiring table or EXCEL table. Through the control of the software, the electrical connector labeling process can be manually controlled to interrupt, adjust, continue to execute, etc.
