[0031] In order to make the technical problem, technical scheme and beneficial effect solved by the utility model clearer and more apparent, the utility model is further explained in detail below in combination with the drawings and examples. It should be understood that the specific examples described here are only used to explain the utility model, and are not used to limit the utility model.

[0032] As Figures 1 to 3 shown, the utility model provides a kind of transport mechanism 30, including automatic transport car 31 and multiple telescopic supports 32, multiple telescopic supports 32 are installed in automatic transport car 31, and the end of multiple telescopic supports 32 away from automatic transport car 31 can all be abutted on ground, and telescopic support 32 can support automatic transport car 31, and multiple telescopic supports 32 can be telescopic, to adjust the levelness of material plate in material box 11 placed on automatic transport car 31.

[0033] Material box 11 is arranged on automatic transport car 31, and can drive material box 11 to move by transport mechanism 30.When the ground is uneven, multiple telescopic supports 32 are telescopically moved, so that automatic transport car 31 can adapt to ground and keep stable, to ensure that material plate in material box 11 is in horizontal state, facilitate the butt joint of material plate and next process, reduce the situation that material plate is transported due to uneven ground.

[0034] Specifically, multiple telescopic supports 32 can be telescopically moved according to the concave-convex change of ground, telescopic support 32 in recessed position is elongated, and telescopic support 32 in protruding position is appropriately shortened.By this kind of accurate adjustment, the vehicle body of automatic transport car 31 can keep stable, to ensure that material plate in material box 11 tends to be horizontal.

[0035] Preferably, automatic transport car 31 is AGV.

[0036] In an embodiment, as Figure 1 shown, automatic transport car 31 has oppositely arranged first side and second side; at least one telescopic support 32 is located at first side, and at least two telescopic supports 32 are located at second side; alternatively, at least one telescopic support 32 is located at second side, and at least two telescopic supports 32 are located at first side.Two telescopic supports 32 are arranged at least three, and three points can uniquely determine a plane in space.When automatic transport car 31 is on uneven ground, a stable support plane is constructed by at least three telescopic supports 32 to ensure the stability of automatic transport car 31 and material plate.And different number of telescopic supports 32 are arranged on opposite sides of automatic transport car 31, to balance the center of gravity, prevent automatic transport car 31 from rolling over or tilting excessively.

[0037] Among them, in horizontal plane, first side and second side can be opposite sides in transverse direction of automatic transport car 31, or opposite sides in longitudinal direction of automatic transport car 31.

[0038] Preferably, telescopic support 32 is provided with three, one of which is arranged at first side, and the remaining two are arranged at second side.

[0039] In an embodiment, as shown in Figure 2 The telescopic support 32 includes a driving member 321 and a support member 322, the driving member 321 is capable of driving the support member 322 to move along the first direction a, so that the support member 322 can abut or be separated from the ground. When the automatic transport vehicle 31 is in the running state, the driving member 321 drives the support member 322 to be separated from the ground, avoiding the interference of the support member 322 with the running of the automatic transport vehicle 31. When the automatic transport vehicle 31 is in the non-running state, the driving member 321 drives the support member 322 to abut the ground, so as to adjust the levelness of the material plate in the loading box 11 of the automatic transport vehicle 31.

[0040] In an embodiment, as shown in Figure 3 The support member 322 includes a connecting rod 3221 and a universal seat 3222, one end of the connecting rod 3221 is connected with the output end of the driving member 321, and the other end of the connecting rod 3221 is provided with a ball hinge head and connected with the universal seat 3222. The ball hinge head enables the connecting rod 3221 and the universal seat 3222 to be adjusted in multiple directions, so that even if the automatic transport vehicle 31 is located on a very uneven ground, the universal seat 3222 can change the posture flexibly according to the actual situation of the ground, so that the universal seat 3222 can well fit the ground, and the stability of the support is ensured.

[0041] The universal seat 3222 is a universal foot cup.

[0042] In an embodiment, as shown in Figure 2 , Figure 3 The telescopic support 32 further includes a bottom plate 323, a screw rod fixing seat 324, a screw rod 325 and a nut seat 326, the screw rod fixing seat 324 is installed on the bottom plate 323, the screw rod 325 is rotatably installed on the screw rod fixing seat 324 through a bearing, one end of the screw rod 325 is connected with the output end of the driving member 321, the other end of the screw rod 325 is threadedly connected with the nut seat 326, and the support member 322 is connected with the nut seat 326.

[0043] The driving member 321 can drive the screw rod 325 to rotate, and through the threaded connection between the screw rod 325 and the nut seat 326, the linear motion of the nut seat 326 along the first direction a is converted, and the support member 322 connected with the nut seat 326 is driven to move along the first direction a. When the driving member 321 drives the screw rod 325 to rotate by a certain angle, the nut seat 326 will move a certain distance along the axial direction of the screw rod 325, so that the telescopic height of the support member 322 can be accurately controlled, so that the automatic transport vehicle 31 can more accurately adapt to the ground difference of different heights, and the material plate can be kept at the required horizontal position, and the accurate butt joint with the next process is facilitated.

[0044] Furthermore, the threaded connection has good self-locking performance. When the support 322 abuts against the ground, the nut seat 326 is not easily moved and can be stably kept at the current position, so that the support height of the support 322 is kept stable.

[0045] As shown in Figure 3 , the driving member 321 comprises a motor 3211 and a speed reducer 3212. The output shaft of the motor 3211 is connected with the input shaft of the speed reducer 3212. The output shaft of the speed reducer 3212 is coaxially connected with the connecting rod 3221 through a shaft coupling. The input shaft of the speed reducer 3212 is perpendicular to the output shaft of the speed reducer 3212.

[0046] In an embodiment, the space between the automatic transport vehicle 31 and the ground is limited. The connecting position of the screw rod 325 on the nut seat 326 and the connecting position of the support 322 on the nut seat 326 are horizontally staggered. Thus, when the nut seat 326 is moved by the screw rod 325, the nut seat 326 can have a larger movement stroke and can reduce the occupied space.

[0047] In an embodiment, as shown in Figure 2 , Figure 3 , the telescopic support 32 further comprises a linear guide rail 327 extending along the first direction a. The linear guide rail 327 is connected between the nut seat 326 and the bottom plate 323. The driving member 321 can drive the nut seat 326 to move along the linear guide rail 327. When the nut seat 326 is moved by the driving member 321, the movement of the nut seat 326 can be guided by the linear guide rail 327, so that the nut seat 326 can only move along the direction of the linear guide rail 327. The shaking and deviation of the nut seat 326 in other directions are effectively limited, so that the linearity and accuracy of the telescopic movement of the support 322 are ensured.

[0048] In an embodiment, as shown in Figure 2 , Figure 3 , the transport mechanism 30 further comprises a switch baffle 33 and a stroke limiting assembly 34. The switch baffle 33 is installed on the nut seat 326. The stroke limiting assembly 34 is installed on the bottom plate 323. The stroke limiting assembly 34 is used to limit the movement stroke of the switch baffle 33, thereby limiting the movement stroke of the support 322. When the nut seat 326 moves along the first direction a, the movement stroke of the nut seat 326 is limited by the cooperation of the switch baffle 33 and the stroke limiting assembly 34, thereby limiting the movement stroke of the support 322. The over-telescopic movement of the support 322 is effectively prevented.

[0049] In an embodiment, the stroke limiting assembly 34 comprises a first stroke switch 341 and a second stroke switch 342, the switch stopper 33 moves between the first stroke switch 341 and the second stroke switch 342 along the first direction a; the first stroke switch 341 is used to limit the highest position of the support 322 moving along the first direction a, and the second stroke switch 342 is used to limit the lowest position of the support 322 moving along the first direction a.

[0050] When the switch stopper 33 moves with the nut seat 326 and triggers the first stroke switch 341, the support 322 stops at the highest position, which can avoid the nut seat 326 colliding with the screw rod fixed seat 324. Similarly, when the switch stopper 33 triggers the second stroke switch 342, the support 322 can stop at the lowest position, which can avoid the nut seat 326 from being separated from the screw rod 325, and at the same time, ensure the height adjustment range of the automatic transport vehicle 31, so that the height of the material plate is always within the set range.

[0051] Preferably, the first stroke switch 341 is a U-shaped photoelectric sensor, and the second stroke switch 342 is a U-shaped photoelectric sensor.

The other adapter plate 35 is installed on the second side of the automatic transport vehicle 31, and the part protruding from the automatic transport vehicle 31 is connected with the bottom plate 323 of the telescopic support 32 on the second side.

[0055] In an embodiment, as shown in Figure 1As shown, the transport mechanism 30 also includes a gyroscope 36 installed on the automated transport vehicle 31. The gyroscope 36 is used to detect the levelness of the upper surface of the automated transport vehicle 31. After the multiple telescopic support members 32 have extended and retracted, the gyroscope 36 detects the state of the automated transport vehicle 31 to determine whether the material plate in the material box 11 is level.

[0056] And / or, the transport mechanism 30 also includes a camera 37 mounted on the automated transport vehicle 31, the camera 37 being used to detect the height of the upper surface of the automated transport vehicle 31. The automated transport vehicle 31 is situated on uneven ground, and the camera 37 can detect changes in the undulations of the automated transport vehicle 31. When the automated transport vehicle 31 tilts, multiple telescopic supports 32 extend and retract, leveling the material tray in the loading bin 11 of the automated transport vehicle 31.
