A chute 41 is arranged at the other end of the swing arm 26. The chute 41 is slidably connected with the fixed column 25 in a matching manner. During use, when the rotating motor 21 rotates, under the cooperation of the turntable 23, the convex column 24 and the chute 41 of the swing arm 26, the swing arm 26 is driven to swing reciprocally around the axis of the fixed column 25. When the sector gear 32 of the swing arm 26 swings reciprocally synchronously, under the meshing connection of the sector gear 32 and the tooth groove 33, the moving rod 28 is driven to move reciprocally along its axial direction on the bases 27.

[0032] Wedge blocks 29 are fixedly installed at both ends of the moving rod 28, and a positioning plate 30 is fixedly installed on the assembly plate 22 on one side of the wedge block 29. A push column 31 is slidably inserted on the positioning plate 30, and a push block 34 is installed at one end of the push column 31. The push block 34 is a rectangular body with an "L" cross-section, and the other end of the push column 31 is an inclined surface, and the inclined push column 31 is in contact and connected with the wedge block 29.

[0033] A clearance hole 35 is provided on the material rack 19 corresponding to the push block 34, and the push block 34 is inserted into the clearance hole 35 in cooperation with the push block 34. A first protrusion 36 is provided on the push column 31 on one side of the positioning plate 30, and a second protrusion 37 is provided on the push column 31 on the other side of the positioning plate 30. A return spring 38 is provided between the second protrusion 37 and the positioning plate 30. A material unloading opening 42 is provided on the side at the other end of the positioning groove of the material rack 19, and one end of the material rack 19 with the material unloading opening 42 is arranged close to the guide plate 14.

[0034] A program controller (Siemens PLCS7-800) is provided on the frame 1 of the network transformer laser coding mechanism. The program controller is electrically connected to the drive motor 5, the rotating motor 21, the laser engraving machine 12 and the in-place sensor 39. The program controller controls the drive motor 5, the rotating motor 21, the laser engraving machine 12 and the in-place sensor 39 to move in sequence and in an orderly manner.

[0035] When the network transformer laser coding mechanism is used, the feeding box 20 equipped with the network transformer is first inserted into the positioning groove of the material rack 19. The network transformer in the material box slides from the storage channel of the feeding box 20 to the positioning groove of the material rack 19 under the action of its own gravity. The first network transformer is in contact and connected with the edge of the material box, and the edge of the material box acts as a limit for the network transformer.

[0036] The driving motor 5 is started, and the driving motor 5 drives the active roller 3 and the driven roller 4 to rotate, and the active roller 3 and the driven roller 4 drive the transmission belt 2 to rotate.

[0037] The rotating motor 21 is started, and the rotating motor 21 drives the turntable 23 to rotate. When the turntable 23 rotates, the boss 24 is driven to rotate around the center of the turntable 23. Through the cooperation of the boss 24 and the slide groove of the swing arm 26, the swing arm 26 is driven to swing back and forth around the axis of the fixed column 25. When the fan gear 32 of the swing arm 26 swings back and forth synchronously, the fan gear 32 is meshed with the tooth groove 33, and the moving rod 28 is driven to reciprocate along its axial direction on the base 27. During the reciprocating movement of the moving rod 28, the wedge blocks 29 at the left and right ends of the moving rod 28 alternately push the corresponding push column 31 to move forward along its axial direction on the positioning plate 30. When the wedge block 29 is reset, the push column 31 is reset in the reset spring. The push block 34 is in the shape of an "L". The push block 34 limits the position of the second network transformer. After the push block 34 is reset, the second network transformer automatically fills the empty position of the first network transformer under the action of its own gravity. As the push column 31 at the corresponding positions on the left and right ends of the moving rod 28 moves forward alternately, the network transformer intermittently slides onto the conveyor belt.

[0038] In the process of the network transformer following the movement of the conveyor belt, the network transformer contacts the guide plate 14, and the posture of the network transformer is corrected by the limiting effect of the guide plate 14, so that it can move smoothly to the bottom of the laser engraving machine 12. When the in-place sensor 39 detects the in-place signal of the network transformer in the feeding channel 15, the signal is transmitted to the program controller, and the program controller controls the laser engraving machine 12 to perform coding on the network transformer. The coded network transformer continues to follow the transmission belt 2 to move into the guide groove 11 of the guide block 7. Under the action of the network transformer's own gravity, it slides along the guide groove 11 to the storage channel of the collecting box 10, thereby completing the laser coding operation of the entire network transformer.

[0039] The network transformer laser coding mechanism intermittently releases the network transformer on the transmission belt 2 in sequence through the cooperation of the fixed frame 18, the material frame 19, the feeding box 20 and the rotating motor 21 of the intermittent feeding component, and the network transformer can be transported through the cooperation of the transmission belt 2, the active roller 3, the driven roller 4 and the driving motor 5 of the conveying component. The feeding channel 15 of the guide plate 14 guides the network transformer and corrects the posture of the network transformer so that the laser engraving machine 12 can print information. The network transformer is guided to the collection box 10 for collection through the guide block 7, thereby completing the laser coding operation of the entire network transformer. The network transformer laser coding mechanism effectively reduces the amount of manual labor and improves the working efficiency of the network transformer laser coding.
