[0021] Please see Figure 1-4 As shown, this utility model is a large sheet metal part transfer device, including a transfer frame 1, on which a pick-and-place mechanism 2 is provided; the pick-and-place mechanism 2 includes a lifting frame 21, which is slidably connected to the transfer frame 1, and two symmetrically arranged U-shaped seats 22 are fixedly connected to the lifting frame 21. Both U-shaped seats 22 are slidably connected to the transfer frame 1. The U-shaped seats 22 are respectively provided with a fixed hole 23 and a movable hole 24. The lifting frame 21 is provided with a rack groove 25, and four rack grooves 25 are provided. Two symmetrically arranged protruding strips 26 are fixedly connected to the lifting frame 21. A drive assembly 3 is provided between the two U-shaped seats 22.

[0022] The drive assembly 3 includes a lifting motor 31 and a rotating rod 32. The lifting motor 31 is mounted on the top of the transfer frame 1. A worm gear 33 is fixedly connected to the output end of the lifting motor 31. Support plates 34 are rotatably connected to both ends of the rotating rod 32. Both support plates 34 are fixedly connected to the transfer frame 1. A worm wheel 35 is fixedly connected to the middle of the rotating rod 32. The worm wheel 35 meshes with the worm gear 33.

[0023] A protective cover can be installed on the worm 33 and worm wheel 35, which can not only prevent dust but also increase the service life of the worm 33 and worm wheel 35. The worm 33 is rotatably connected to the protective cover, and the protective cover is installed on the top of the transfer frame 1 by bolts.

[0024] Both ends of the rotating rod 32 are fixedly connected to main sprockets 36. The two sets of main sprockets 36 respectively mesh with two independent chains 37 to drive the corresponding slave sprockets 38 to rotate. A rotating shaft 39 is fixedly connected to the slave sprocket 38 and is fixedly connected to the transfer frame 1.

[0025] The chain 37 passes through the fixed hole 23 and the movable hole 24 on the corresponding side in sequence and is fixedly connected to the fixed hole 23.

[0026] The input end of the lifting motor 31 is connected to an external power source. The chain 37 is fixedly connected to the pin in the fixing hole 23. The lifting motor 31 drives the worm 33, worm wheel 35 and rotating rod 32 to rotate. In conjunction with the main sprocket 36, chain 37 and driven sprocket 38, the lifting frame 21 is lifted and lowered. It can pick up and put down any layer of pallet 42, has high mobility, and is convenient for inspecting the sheet metal parts on the pallet 42.

[0027] The transfer frame 1 is equipped with a propulsion mechanism 4, which includes a discharge generator 41, a tray 42, and a support bar 46. There are two discharge generators 41, which are respectively installed on both sides of the lifting frame 21. The output end of the discharge generator 41 passes through the lifting frame 21 and is fixedly connected to a gear 43. There are multiple trays 42, and roller groups 44 are rotatably connected to both sides of the multiple trays 42. The two roller groups 44 are respectively rolled between the corresponding side protrusion bar 26. Two symmetrically arranged racks 45 are fixedly connected to the bottom of the tray 42. The gear 43 meshes with the corresponding side rack 45. There are two support bars 46, which are fixedly connected to the transfer frame 1.

[0028] The roller assembly 44 does not contact the transfer frame 1, and the width of the rack 45 is slightly smaller than the width of the rack groove 25 to reduce friction.

[0029] The bottom of the tray 42 has two symmetrical guide grooves 47, and guide bars 48 are slidably connected in both guide grooves 47. The guide bars 48 are fixedly connected to the support bars 46 on the corresponding side. The support bars 46 are slidably connected to the tray 42. The tray 42 is slidably connected to the lifting frame 21 and the protruding bar 26 respectively.

[0030] The discharge motor 41 drives the gear 43 to rotate, and the rack 45 makes the pallet 42 slide from the support bar 46 to the top of the lifting frame 21. The roller group 44 can reduce friction, and the uniform support force of the pallet 42 avoids the deformation and warping of large sheet metal parts after transfer and punching, thus realizing the purpose of fully automatic picking and placing of sheet metal parts.

[0031] This device, in conjunction with a robotic arm and vacuum suction cups, enables the handling of large sheet metal parts. It can also be used with trolleys or forklifts to transport large sheet metal parts in batches, saving time and effort while increasing work efficiency.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] The working principle of this utility model is as follows: The lifting motor 31 drives the worm gear 33 to rotate, which in turn drives the rotating rod 32, the worm wheel 35 and the main sprockets 36 at both ends to rotate. Through the meshing transmission of the chain 37, the chain 37 drives the sprocket 38 to rotate. The chain 37 rises on the side of the fixed hole 23 and falls on the side of the movable hole 24, and drives the U-shaped seat 22 and the lifting frame 21 to rise. When the lifting frame 21 rises to the appropriate position, the discharge motor 41 drives the gear 43 to rotate, which causes the rack 45 to drive the support plate 42 to slide from the support bar 46 onto the lifting frame 21. At the same time, the roller group 44 rolls onto the protruding bar 26.
