It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present utility model. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concepts of the present utility model.

[0023] As Figures 1 - 2 shown, a pick-and-place fixture for stamping automotive parts proposed by the present utility model includes a workbench 1. A first slide rail 10 is provided on the back plate of the workbench 1. A feeding device 2 is also provided on the back plate of the workbench 1. A stamping table 11 is provided in the middle of the workbench 1. An "H"-shaped installation groove 12 is formed on one side of the stamping table 11. A blanking fixture 3 is provided in the installation groove. A conveyor belt 13 is provided on one side end face of the workbench 1 close to the "H"-shaped installation groove 12.

[0024] As an optimized solution of the present utility model, by providing a transfer table on the side of the workbench 1, the stamped parts can be automatically sent to the storage point, which is more convenient and improves efficiency.

[0025] As Figure 3 shown, the feeding device 2 includes a motor 20 provided on the back surface of the back plate of the workbench 1. A transmission block 21 is provided on the transmission end of the motor 20. A movable rod 22 is movably provided on the side of the transmission block 21 away from the transmission end of the motor 20. A connecting block one 23 is provided at one end of the movable rod 22. A second slide rail 24 is provided at the bottom of the connecting block one 23. A connecting block two 26 is provided at the bottom of the second slide rail 24. An air guide exhaust pipe 27 is provided on the connecting block two 26. A plurality of suction cups 28 are provided on the bottom ports of the air guide exhaust pipe 27. The suction port at the top of the air guide exhaust pipe 27 is connected to an air extraction device.

[0026] As Figures 4 - 6As shown in the figure, the loading device 2 further includes a slider 25 slidably arranged on the first slide rail 10. A chute 29 is formed at the front end of the slider 25, and the second slide rail 24 is slidably arranged in the chute 29; the unloading fixture 3 includes a rotating shaft 30 horizontally arranged in the "H"-shaped mounting groove 12. A "U"-shaped frame 32 is arranged on the rotating shaft 30. A clamping assembly 34 is arranged on one side of the "U"-shaped frame 32 away from the rotating shaft 30. A transmission gear 31 is arranged on one side of the rotating shaft 30, and a transmission assembly 33 is arranged below the transmission gear 31; the clamping assembly 34 includes a pair of second telescopic electric cylinders 340 respectively arranged on the side plates on both sides of the "U"-shaped frame 32.
