[0018] Further, the translation driving mechanism includes a translation driving motor 63, a translation driving lead screw 67, two support rails 55 and two translation support seats 54; the two support rails 55 are installed in parallel, and the two translation support seats 54 are respectively installed on the two support rails 55 in a movable manner; a driving support beam 66 is connected and installed between one ends of the two support rails 55, and a translation support beam 65 is connected and installed between the two translation support seats 54; one end of the translation driving lead screw 67 is rotatably installed in the middle of the driving support beam 66, and the other end is threadedly engaged and installed through the middle of the translation support beam 65; the translation driving motor 63 is installed on the driving support beam 66 and drives the translation driving lead screw 67 to rotate; the translation driving motor 63 is driven and controlled by the unloading control unit 1.

[0019] By using the cooperation between the translation support beam 65 and the translation driving lead screw 67, the synchronous translation driving of the two translation support seats 54 can be realized, ensuring the stability of the overhanging movement of the component 100 to be transported.

[0020] Further, roller grooves 56 are provided on both vertical side surfaces of the two support rails 55; the translation support seat 54 is a U-shaped support seat, and each support roller 68 is rotatably installed on the inner wall of the translation support seat 54, and the support roller 68 supports and travels in the corresponding roller groove 56.

[0021] By using the cooperation between the support roller 68 and the roller groove 56, the movable installation of the translation support seat 54 can be realized, and it has relatively small moving resistance and good moving stability.

[0022] Further, the steering driving mechanism includes a bottom support plate 53, a support turntable 52, a driving gear ring and a steering driving motor 64; the bottom support plate 53 is horizontally installed on the translation driving mechanism, and the center of the lower side surface of the support turntable 52 is rotatably installed at the center of the upper side surface of the bottom support plate 53; a driving ring groove is provided on the lower side surface of the support turntable 52 around the rotation center, and the driving gear ring is fixedly installed in the driving ring groove; the steering driving motor 64 is fixedly installed on the bottom support plate 53, and a driving pinion meshing with the driving gear ring is provided at the end of the output shaft; the steering driving motor 64 is driven and controlled by the unloading control unit 1.

[0023] By installing the driving gear ring on the support turntable 52 and thus being rotationally driven by the steering driving motor 64, the support turntable 52 rotates, causing the lifting driving mechanism installed thereon to turn, meeting the adjustment requirements for different positions.

[0024] Furthermore, the lifting drive mechanism includes a height adjustment motor 49, a height adjustment lead screw 62, two lifting support columns 48, and two lifting support sliding sleeves 51. The two lifting support columns 48 are vertically installed on the steering drive mechanism, and the two lifting support sliding sleeves 51 are respectively installed on the two lifting support columns 48 in a sliding manner.

[0025] With the cooperation of the lifting support columns 48 and the lifting support sliding sleeves 51, good lifting stability can be achieved to ensure stable support for the cantilever support mechanism.

[0026] Furthermore, the cantilever support mechanism includes a rotation drive motor 47, a gear transmission unit, a gearbox 46, two cantilever support rods 42, and two lifting bandages 45.

The rotation drive motor 47 is installed on the gearbox 46, the gear transmission unit is installed in the gearbox 46, and the rotation drive motor 47 drives the two cantilever support rods 42 to rotate synchronously and reversely through the gear transmission unit.

The rotation drive motor 47 is driven and controlled by the unloading control unit 1.

[0027] Two bandage supports 44 are used to install the lifting bandage 45, so that the lifting bandage 45 is tightly arranged above the cantilever support rod 42, for flexibly supporting the lower side of the component 100 to be transported. Moreover, there is no requirement for the shape of the lower side of the component 100 to be transported, and it can adapt to the shape of the lower side, with strong adaptability, and it will not cause damage to the lower side, having good anti-slip and protection performance; through the rotation drive motor 47, the gear transmission unit and the gearbox 46, the synchronous reverse rotation drive of the two cantilever support rods 42 can be realized, so that when the two cantilever support rods 42 are inserted under the component 100 to be transported from the side, the bandage support 44 and the lifting bandage 45 are rotated to the side, and it can be smoothly inserted without too high a clearance. Before lifting, the bandage support 44 and the lifting bandage 45 are rotated above the cantilever support rod 42 again, and the component 100 to be transported can be slightly lifted during the rotation process.

[0029] The gear transmission unit can be used to realize the synchronous reverse rotation drive of the two third bevel gears 60, so that a better force balance effect can be achieved when the two lifting bandages 45 and the lower side of the component 100 to be transported are in friction.

[0030] Further, a strip-shaped buffer pad 43 is arranged on the cantilever support rod 42 and near the lifting bandage 45 for support when the lifting bandage 45 is pressed and bent. The strip-shaped buffer pad 43 can be used to realize bottom protection to prevent the component 100 to be transported from rigidly colliding with the cantilever support rod 42.

[0033] When the unloading device for an AGV cart disclosed by the present utility model is in use, after the AGV cart loaded with the component 100 to be transported reaches the unloading position, the controller drives and controls the movement drive motor 63 and the height adjustment motor 49 according to the control command received from the host computer by the wireless communication module, so that the two cantilever support rods 42 are horizontally inserted into the gap below the component 100 to be transported, then drives and controls the rotation drive motor 47, so that the two lifting bandages 45 are close to the bottom of the component 100 to be transported, then drives and controls the height adjustment motor 49, so that the two cantilever support rods 42 rise, and the component 100 to be transported is flexibly supported by the two lifting bandages 45 and is away from the support platform plate 1, and then drives and controls the movement drive motor 63, the height adjustment motor 49, and the steering drive motor 64, so that the component 100 to be transported is cantilever transported to the designated position.

[0034] As described above, although the present utility model has been shown and described with reference to specific preferred embodiments, it should not be construed as a limitation of the present utility model itself.
