[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] The real-time wire feeding speed acquisition mechanism of this utility model includes an insulating shell 9, with a wire inlet 2 at the top and a wire outlet 8 at the bottom. Inside the insulating shell 9 are an absolute encoder 12, a wire feeding clamping structure, and a data set interaction device 13. The wire feeding clamping structure includes an auxiliary wheel 6, a data acquisition drive wheel 7, a pressing mechanism 3, and a cover plate 11 connected in sequence. The data acquisition drive wheel 7 is connected to the encoder spindle 15 of the absolute encoder 12. The data set interaction device 13 is connected to the absolute encoder 12 via a ribbon cable and is also connected to a power supply and communication port 1 via a ribbon cable.

[0019] The power and communication ports 1 of this invention are located on the top of the insulating housing 9. The pressing mechanism 3 is connected to the clamping mechanism body 10 via a cover plate 11 and a pressing spring 14. The front of the clamping mechanism body 10 is provided with an auxiliary wheel 6, a collection drive wheel 7, and the pressing mechanism 3. The auxiliary wheel 6 cooperates with the collection drive wheel 7 through the pressing mechanism 3 to collect the wire feeding speed. The surface of the insulating housing 9 is provided with a communication indicator light 4 and a power indicator light 5. The insulating housing 9 has a cuboid structure, and the top of the insulating housing 9 is connected to the clamping mechanism body 10 by screws.

[0020] The active acquisition wheel 7 of this invention is fixed to the internal mandrel by a set screw, and the welding wire is clamped by the pressing mechanism 3 and the auxiliary wheel 6. This invention can communicate and upload data in real time with an external MES system through the power supply and communication port 1, and can also be connected to other production and manufacturing systems to collect and store wire feeding speed data.

[0021] In use, 1) Insert the welding wire into the wire inlet 2 and adjust the distance between the acquisition drive wheel 7 and the auxiliary wheel 6 by pressing the top pressure mechanism 3 so that the welding wire can pass through normally. The welding wire exits from the wire outlet 8 and passes through the wire feeder to the welding gun head to start welding and collect data; 2) Connect the wire outlet 8 to the inlet of the welding machine's wire feeding mechanism and fix it with the matching screw to place the wire feeding speed acquisition mechanism of this utility model in the wire feeding circuit; 3) Connect the power supply and communication port 1 to the 24V power supply and RS485 interface to realize the connection to MES for real-time acquisition; 4) The auxiliary wheel 6 cooperates with the acquisition drive wheel 7 through the top pressure mechanism 3 to collect the wire feeding speed; 5) When the welding wire is used up, squeeze the top pressure mechanism 3 to separate the acquisition drive wheel 7 and the auxiliary wheel 6, so that the welding wire can be pulled out from the circuit.
