[0046] When the electric cylinder 101 extends the piston rod, it pushes the slide plate 102 and the motor 103 to move, so that the driving gear 104 is meshed with the assembly spur gear 1 201, and the assembly spur gear 1 201 drives the assembly spur gear 2 203 to rotate through the toothed synchronous belt 1 202; the assembly spur gear 203 drives the threaded rod 211 to rotate and drives the push block 212 to slide, and the push block 212 pushes a lower shell 4 in the storage shell plate 107 onto the toothed conveyor belt 313, so that the lower shell 4 reaches the first station.

[0047] The rotation of the assembly spur gear 201 drives the assembly rocker 204 to swing, drives the lifting plate 205 to rise and fall, drives the lifting bracket 206 to slide on the main bracket 105, drives the connecting plate 207 and the adapter block 208 to move downward, and when the adapter block 208 moves downward, multiple rollers 210 slide in the arc guide groove of the adapter block 208, so that the rollers 210 cannot support the vortex generator 5, and the vortex generator 5 falls and gets stuck in the groove of the toothed conveyor belt 313, and is assembled at the first end of the lower shell 4 at the same time; at the same time, the downward moving connecting plate 207 presses down the interface 9 at the opening position of the guide shell plate 2 108, and during the downward movement of the interface 9, the reset plate 214 is pushed to rotate, and then the interface 9 is assembled at the second end of the lower shell 4, and is out of contact with the reset plate 214, and the reset plate 214 is reset under the elastic force of the torsion spring 213; at this time, the second station completes the assembly.

At this time, the third workstation completes the assembly.

[0049] The downwardly moved lifting bracket 206 drives the welding gun 7 to descend, and the welding gun 7 welds the semi-finished workpiece at the fourth workstation.

[0050] The downward moving lifting bracket 206 drives the rack 223 to move downward and drives the matching gear 224 to rotate. The rotation of the matching gear 224 drives the placement plate 226 and the upper cover 8 placed on the placement plate 226 to rotate, so that the upper cover 8 is flipped one hundred and eighty degrees and then buckled on the lower shell 4. The assembly is completed at the fifth station. The matching gear 224 also drives the hammer block 225 to rotate. The hammer block 225 rotates to hammer the workpiece at the sixth station, pressing the upper cover 8 against the lower shell 4 to realize the assembly and welding of the sensor.
