[0044] See also Figure 1-3 The utility model provides a transfer system, which includes a transfer vehicle 7 and a station support mechanism. The transfer vehicle 7 is used to carry and transfer the workpiece. The station support mechanism is arranged at the processing station and is used to support and process the workpiece.

[0045] Furthermore, the top of the transfer vehicle 7 can carry and lock the workpiece to drive the workpiece to move to the processing station, and can transfer the workpiece to the station support mechanism for processing.

[0046] Specifically, a pressure plate for pressing the workpiece against the top of the transfer cart 7 is provided on the transfer cart 7 , and bolts can be inserted into the pressure plate and fixed on the transfer cart 7 to lock the workpiece on the transfer cart 7 .

[0047] Preferably, the transfer vehicle 7 carries a plurality of horizontally arranged plate-shaped workpieces to drive the workpieces to be transferred to the work station support mechanism for welding as a whole.

[0048] Specifically, wheels 71 are provided on both sides of the bottom of the transfer vehicle 7 , and the wheels 71 are used to drive the transfer vehicle 7 to move.

[0049] Preferably, guide wheels 72 are provided on both sides of the transfer vehicle 7, and the guide wheels 72 are used to guide the moving direction of the transfer vehicle 7. More preferably, there are multiple guide wheels 72, which are respectively provided on both sides of the transfer vehicle 7 to guide the moving direction of the transfer vehicle 7 more stably.

[0050] Specifically, a horizontally extending positioning plate 73 is provided at one end of the transfer vehicle 7, and a vertically oriented locking hole 731 is provided on the positioning plate 73. The positioning plate 73 and the locking hole 731 are used to lock the transfer vehicle 7 on the workstation support mechanism to avoid horizontal displacement during processing.

[0051] Preferably, the locking hole 731 is a square hole to prevent the transfer vehicle 7 from rotating when locked on the station support mechanism.

[0052] Furthermore, the workstation support mechanism includes a support frame 1 , a first track 2 and a locking member 3 .

[0053] The first track 2 is arranged on the support frame 1, and the first track 2 includes a first inclined rail 21 and a first horizontal rail 22. The first end of the first inclined rail 21 extends to the ground, and the second end extends to dock with the first end of the first horizontal rail 22. The first inclined rail 21 and the first horizontal rail 22 can guide the transfer vehicle 7 to move. The locking member 3 is arranged on the support frame 1, and the locking end 31 of the locking member 3 can be lifted and moved.

[0054] During use, when the transfer vehicle 7 moves onto the first horizontal rail 22 , the locking end 31 of the locking member 3 can be lifted and lowered to be inserted into and out of the locking hole 731 on the transfer vehicle 7 .

[0055] The specific working principle of the transfer system is as follows: when the transfer vehicle 7 needs to transfer the workpiece to the workstation support mechanism at the processing station, it can move along the first inclined rail 21 and the first horizontal rail 22 in sequence and be supported on the first horizontal rail 22, and then the locking member 3 is inserted into the locking hole 731 on the transfer vehicle 7 to lock the horizontal position of the transfer vehicle 7 to prevent the workpiece from shaking during processing. At this time, the workpiece on the transfer vehicle 7 is in a processing state. When the workpiece on the transfer vehicle 7 is processed, the locking end 31 of the locking member 3 can be disengaged from the locking hole 731, and the transfer vehicle 7 can drive the workpiece to move to the ground along the first horizontal rail 22 and the first inclined rail 21 in sequence, and continue to drive the workpiece to be transferred to the next station or unloaded.

[0056] Therefore, during the transfer process of the transfer system, the transfer vehicle 7 always supports and locks the workpiece, and there is no need to repeatedly lock and unlock the workpiece. The transfer vehicle 7 can automatically drive the workpiece to move and lock it to the workstation support mechanism, and unlock it from the workstation support mechanism and move it to the ground. The above transfer process is simple and fast.

[0057] At the same time, the transfer system is particularly suitable for the transfer of multiple horizontally arranged large plate-shaped workpieces and welding between workpieces. After the transfer vehicle 7 carrying multiple horizontally arranged large plate-shaped workpieces can drive the workpieces to move along the first inclined rail 21 and support them on the first horizontal rail 22, the multiple workpieces carried by the transfer vehicle 7 are in a horizontal state, so that welding mechanisms such as welding robots on the workstation support mechanism can weld the gaps between the multiple horizontally arranged plate-shaped workpieces to weld them as a whole.

[0058] Furthermore, the support frame 1 is a frame with an open upper end and a first side, and track frames 11 are arranged on opposite side walls of the support frame 1. There are two first tracks 2, and the two first tracks 2 are arranged on the tops of the two track frames 11, respectively, and the track frames 11 are used to support the first tracks 2.

[0060] Furthermore, the workstation support mechanism also includes two second rails 5 .

[0061] The two second rails 5 are respectively disposed on opposite side walls of the support frame 1 and are located above the rail frame 11 . The cross-sections of the two second rails 5 are U-shaped, and the openings of the two second rails 5 are opposite to each other.

[0062] The two second rails 5 are respectively used to insert and guide the guide wheels 72 on both sides of the transfer vehicle 7 to move, so as to improve the movement accuracy of the transfer vehicle 7 and prevent the transfer vehicle 7 from deviating from the first rail 2.

[0063] Specifically, the second track 5 includes a second inclined rail 51 and a second horizontal rail 52 . The first end of the second inclined rail 51 extends to the ground, and the second end extends to butt with the first end of the second horizontal rail 52 .

[0064] When in use, when the wheel body 71 at the bottom of the transfer vehicle 7 moves along the first inclined rail 21 and the first horizontal rail 22, the guide wheel 72 on its side can move along the second inclined rail 51 and the second horizontal rail 52 at the same time to guide the entire transfer process of the transfer vehicle 7 and improve the accuracy of the movement of the transfer vehicle 7 along the first track 2.

[0065] Specifically, one end of the second inclined rail 51 close to the ground passes through the first side of the support frame 1 , so that the guide wheel 72 can be inserted through the opening of the second inclined rail 51 .

[0066] Furthermore, the workstation support mechanism also includes a fixing frame 4 .

[0067] The main body of the locking member 3 is fixed to the second side of the support frame 1 relative to the first side through the fixing frame 4, and the locking end 31 is a vertically oriented square column to prevent the transfer vehicle 7 from moving horizontally when the locking end 31 is inserted into the locking hole 731 on the transfer vehicle 7, and to prevent the locking end 31 and the transfer vehicle 7 from rotating relative to each other.

[0068] Specifically, the locking member 3 is a cylinder, a hydraulic cylinder or an electric cylinder, the cylinder body of the locking member 3 is fixed on the fixing frame 4, and the locking end 31 is a piston. The cylinder body can drive the locking end 31 to move up and down.

[0069] More specifically, the locking end 31 may be arranged at the following two positions:

[0070] The first setting mode is: the locking end 31 is set at the top of the cylinder body, the locking end 31 can correspond to the bottom of the locking hole 731 on the transfer vehicle 7, and the locking end 31 can move upward and be inserted into the locking hole 731.

[0071] The second setting mode is: the locking end 31 is set at the bottom of the cylinder body, the locking end 31 can correspond to the top of the locking hole 731 on the transfer vehicle 7, and the locking end 31 can move downward and be inserted into the locking hole 731.

[0072] Specifically, the fixing frame 4 is fixed to the supporting frame 1 by bolts or welded.

[0073] Furthermore, the workstation support mechanism also includes a distance sensor 6 .

[0074] The distance sensor 6 is disposed on the second side of the support frame 1 relative to the first side. The distance sensor 6 can face the transfer vehicle 7 on the first horizontal rail 22 to monitor the distance between the transfer vehicle 7 and the second end of the first horizontal rail 22 to improve the accuracy of workpiece processing.

[0075] Specifically, the workstation support mechanism also includes a PLC controller, and the distance sensor 6 and a driving mechanism such as a motor on the transfer vehicle 7 for driving the wheel body 71 to rotate are all communicatively connected to the PLC controller.

[0076] When the distance sensor 6 detects that the distance between the transfer vehicle 7 and the second end of the first horizontal rail 22 reaches a threshold, the PLC controller receives the signal sent by the distance sensor 6 and sends a stop signal to the drive mechanism on the transfer vehicle 7. The drive mechanism controls the wheel body 71 to stop rotating, so as to achieve precise control of the parking position of the transfer vehicle 7.

[0077] Specifically, the distance sensor 6 is a laser rangefinder.

[0078] Furthermore, the workstation support mechanism also includes a limiting member 12 .

[0079] The limit member 12 is extended upwardly and is arranged on the track frame 11 corresponding to the second end of the first horizontal rail 22. The limit member 12 is used to limit the moving position of the transfer vehicle 7 on the first horizontal rail 22 to improve the accuracy of the processing position of the workpiece carried by the transfer vehicle 7.

[0080] Specifically, a pressure sensor is arranged on one side of the limit member 12 close to the first horizontal rail 22, and the workstation support mechanism further includes a PLC controller. The pressure sensor and a driving mechanism on the transfer vehicle 7 for driving the wheel body 71 to rotate are both communicatively connected to the PLC controller.

[0081] When the wheel body 71 at the front end of the transfer vehicle 7 moves along the first horizontal rail 22 to the pressure sensor against the limit member 12, the PLC controller receives the signal sent by the pressure sensor and sends a stop signal to the drive mechanism on the transfer vehicle 7. The drive mechanism controls the wheel body 71 to stop rotating, so as to achieve precise control of the parking position of the transfer vehicle 7.

[0082] Specifically, the limiting member 12 is a plate or a rod that is welded or bolted to the track frame 11 .

[0083] Preferably, the distance sensor 6 and the limiter 12 are provided at the same time to further improve the parking position accuracy of the transfer vehicle 7 .
