[0047] In this embodiment, please refer to Figure 3-Figure 8 The push-pull mechanism 3 includes a moving component and a connecting structure 33. The connecting structure 33 is arranged on the moving component. The moving component is movably arranged on the mobile chassis 1. The moving component moves to be relatively close to or away from the workstation to pull the pallet from the workstation or push the pallet to the workstation. When the moving component drives the pallet to move, the pallet needs to be connected to the moving component through the connecting structure 33; when the pallet is transported to the destination workstation, the connecting structure 33 disconnects the pallet from the moving component. The controller is communicatively connected to the moving component and the connecting structure 33, controls the moving component to move relative to the mobile chassis 1, and controls the connecting structure 33 to connect or disconnect the pallet from the moving component.

[0048] Furthermore, the mobile assembly includes a telescopic structure 31 and a pulling structure 32, the telescopic structure 31 is movably arranged on the mobile chassis 1, the pulling structure 32 is movably arranged on the telescopic structure 31, and the connecting structure 33 is arranged on the pulling structure 32, and the moving directions of the pulling structure 32 and the telescopic structure 31 are consistent with the extension direction of the fixed guide rail, that is, they can be relatively close to or away from the workstation. The telescopic structure 31 and the pulling structure 32 are both communicatively connected to the controller, which controls the pulling structure 32 to move relative to the telescopic structure 31 and controls the telescopic structure 31 to move relative to the mobile chassis 1, so as to load the pallet onto the mobile chassis 1 or unload the pallet to the destination workstation.

[0049] Furthermore, the telescopic structure 31 includes a telescopic plate 311 and a second transmission assembly. A groove 9 is provided on the mobile chassis 1. The length direction of the groove 9 is consistent with the extension direction of the fixed guide rail. The telescopic plate 311 is slidably arranged in the groove 9. The second transmission assembly is arranged between the telescopic plate 311 and the groove bottom of the groove 9. The second transmission assembly is connected to the telescopic plate 311 and is communicatively connected to the controller. The controller controls the second transmission assembly to drive the telescopic plate 311 to move along the length direction of the groove 9.

[0050] The pulling structure 32 includes a pulley 321 and a third transmission assembly arranged on the telescopic structure 31. The connecting structure 33 is arranged on the pulley 321. The third transmission assembly is connected to the pulley 321 and is communicatively connected to the controller. The controller controls the third transmission assembly to drive the pulley 321 to move relative to the telescopic structure 31 along the length direction of the telescopic structure 31.

[0051] In a specific embodiment, a groove 9 is provided on the mobile chassis 1 in the same direction as the extension direction of the fixed guide rail, and a telescopic plate 311 with a plurality of guide wheels 10 on both sides is arranged in the groove 9, and slides more smoothly along the groove 9 under the action of the guide wheels 10. The second transmission assembly includes a motor 4 and a gear chain assembly, specifically, a chain 6 is fixedly connected under the telescopic plate 311, and the length direction of the chain 6 is parallel to the length direction of the groove 9, the motor 4 and the gear 5 are arranged in the groove 9, the motor 4 is connected to the shaft 7, and the shaft 7 is provided with a bearing 8 and a gear 5, and the gear 5 is meshed with the chain 6, and the controller controls the motor 4 to work.

[0052] The third transmission assembly also includes a motor 4 and a gear chain assembly. Specifically, a ring chain 322 is provided around the telescopic plate 311. The transmission direction of the ring chain 322 is consistent with the length direction of the telescopic plate 311. The ring chain 322 is meshed with a plurality of sprockets 323. Each sprocket 323 is connected to the telescopic plate 311. The pulley 321 is fixedly connected to the part of the ring chain 322 located above the telescopic plate 311. The motor 4 is connected to the sprocket 323 to drive the sprocket 323 to rotate, and then transmits with the ring chain 322 to move the pulley 321 relative to the telescopic plate 311. The controller is communicatively connected to the motor 4. Guide wheels 10 are provided on both sides of the pulley 321, and the guide wheels 10 cooperate with the groove 9. The connecting structure 33 is arranged on the pulley 321.

[0053] The telescopic plate 311 cooperates with the pulley 321, and the pallet is pulled onto the mobile chassis 1 or pushed onto the fixed guide rail of the workstation by the movement of the two. In this way, the setting of the pulley 321 does not require a large stroke of the telescopic plate 311, and the pulley 321 is small in size, making it more convenient to move.

[0054] In this embodiment, please refer to Figure 9-12The connecting structure 33 is arranged on the pulley 321, and includes a push rod mechanism and a latch 333. The push rod mechanism is connected to the latch 333 and is communicatively connected to the controller. The controller controls the push rod mechanism to drive the latch 333 to move between the third position and the fourth position; when the latch 333 moves to the third position, the end of the latch 333 extends into the pin hole of the tray, so that the moving component is connected to the tray. Specifically, the pulley 321 is connected to the tray through the latch 333, which facilitates the pulley 321 to drive the tray to move; when the latch 333 moves to the fourth position, it withdraws from the pin hole of the tray and is located outside the pin hole of the tray, and the moving component is disconnected from the tray, that is, at this time the pulley 321 can no longer drive the tray to move, which facilitates the pulley 321 to return to its original position.

[0055] Furthermore, the connecting structure 33 also includes a connecting plate 332 connected to the push rod mechanism and an elastic member. The connecting plate 332 is provided with a through hole for the plug 333 to penetrate, and the plug 333 can slide in the through hole. The elastic member acts between the connecting plate 332 and the plug 333. The push rod mechanism drives the connecting plate 332 to move, and the connecting plate 332 drives the plug 333 to move through the elastic member.

[0056] In a specific embodiment, the push rod mechanism can be, but is not limited to, an electric push rod 331, which is communicatively connected to the controller, and the end of the telescopic rod of the electric push rod 331 is connected to a connecting plate 332, and a through hole is provided on the connecting plate 332 at the side of the telescopic rod, and a plug 333 is inserted into the through hole, and the inner diameter of the through hole is slightly larger than the outer diameter of the plug 333, and the length direction of the plug 333 is parallel to the telescopic direction of the telescopic rod. A step structure 334 is provided on the outer wall of the plug 333, and the elastic member is a spring 337 sleeved on the plug 333, and one end of the spring 337 is against the step structure 334 and the other end is against the connecting plate 332. The electric push rod 331 is connected to the pulley 321 through a support frame 335, and a slide rail slider assembly 338 is also provided between the support frame 335 and the connecting plate 332, and the length direction of the slide rail is parallel to the telescopic direction of the telescopic rod. A guide sleeve 336 is further provided on the support frame 335 at a position corresponding to the latch pin 333 , and the latch pin 333 is inserted into the guide sleeve 336 , so that the latch pin 333 has better stability when moving.

[0057] With such arrangement, when the latch 333 is not aligned with the pin hole, the position of the latch 333 does not change when the telescopic rod is extended or retracted. At this time, the connecting plate 332 moves relative to the latch 333 and compresses the spring 337. The arrangement of the spring 337 serves to protect the electric push rod 331.

[0058] The present invention also provides a method for transferring transformer coils. The method is based on the fully automatic transfer vehicle for the casting and curing line in the above embodiment, and the specific steps include:
