With the rapid growth of the information industry, optical communication is rapidly developing and replacing conventional communication technologies in order to meet the increasing demands for high rates and data throughput. From consumer electronics to supercomputers and large data centers, optical communication is becoming the first choice for communication in many situations. With the maturation of 5G technology, the number of required fiber optic connectors has increased substantially.

For fiber penetration, if the precision of the tool fixture cannot be guaranteed, the size parameters of the product cannot be guaranteed, or the phenomenon of fiber breakage easily occurs in the assembling process; for glue injection, a handheld glue injection machine is adopted for glue injection at present, glue amount is completely controlled by workers according to proficiency, and therefore some produced products need secondary glue supplement or some products need scraping when the glue amount is too much. However, in the production process, the tool clamp is worn for a long time, the precision is difficult to guarantee for a long time, and if the production time is longer, the tool clamp is worn more seriously, so that the tool clamp needs to be maintained for a long time, and time and labor are wasted; the process is completely manually operated at present, so that the influence of human factors on the process is great, and the size parameters cannot be accurately controlled; generally, the requirements of the optical fiber connector on performance parameters and size parameters are relatively high, so that the product performance is changed and the product consistency is difficult to realize due to abrasion of a tool clamp and difference of human factors.

The comprehensive complaint is made, the fiber penetrating process in the existing optical fiber connector production has the problems of low efficiency, frequent maintenance of a tool clamp, large influence of human factors, difficulty in controlling the requirements of size parameters and performance parameters and difficulty in realizing the consistency of products in the prior art, so that the service life of the optical fiber connector is influenced, the successful coupling rate is influenced and the like. Therefore, the prior art still needs to be improved and developed.

When the telescopic rod of the pushing cylinder 141 retracts, the tail end of the push rod 144 retracts to enable the lower end of the stock storage groove 1431 to be communicated with the output channel 1421, at this time, the lowermost mortise workpiece 200 in the stock storage groove 1431 can fall into the output channel 1421, then the push rod 144 descends under the action of the pushing cylinder 141, the mortise workpiece 200 is pushed out from the output channel 1421, so that the mortise workpiece 200 moves to a position where the mortise workpiece abuts against the stopping portion 146, and the positioning portion 147 above is used for positioning, so that the mortise workpiece 200 is prevented from falling; the grabbing manipulator 40 can clamp the two opposite sides of the mortise workpiece 200 under the action of the moving platform 30, and then drive the mortise workpiece 200 to move a distance in the direction of the guide seat 142 to be separated from the limitation of the positioning portion 147, so that the feeding mechanism 14 can be moved out from above, and the workpiece grabbing action of the grabbing manipulator 40 is completed.

In one embodiment, referring to fig. 13, the optical fiber clamp 15 includes a base and a cover plate 152 rotatably disposed on the base 151, wherein a positioning groove 1511 for accommodating the optical fiber 300 is formed on an upper surface of the base 151, and the positioning groove 1511 extends along the X-axis direction and penetrates through an end portion adjacent to the grasping robot 40; the cover plate 152 can rotate to the upper surface of the base 151 and at least cover a section of the positioning groove 1511; and a magnetic attraction structure is disposed between the base 151 and the cover plate 152.
