[0021] The self-positioning mechanism 5 comprises support shells 51, clamping plates 52, positioning rotating plates one 55 and torsion springs one 56. The support shells 51 are arranged at the left and right ends of the rack 1 respectively. The inside of each support shell 51 is elastically limited by a clamping plate 52. The lower end of each clamping plate 52 is rotationally connected with a positioning rotating plate one 55 through a rotating shaft one. The rotating shaft one outer arc surface of the positioning rotating plate one 55 is movably sleeved with a torsion spring one 56. The front end of the torsion spring one 56 is fixedly connected with the clamping plate 52, and the rear end of the torsion spring one 56 is fixedly connected with the positioning rotating plate one 55. During the stacking of the trays, for the trays that are not properly placed, under the torsion of the torsion spring one 56, the positioning rotating plate one 55 applies a left-right force to the trays to adjust the position of the trays. For the properly placed trays, as the trays move upwards, under the guidance of the positioning rotating plate one 55, the trays will enter between the two clamping plates 52. The clamping plates 52 clamp the properly placed trays from left and right. The friction between the clamping plates 52 and the properly placed trays reduces the pressure exerted by the properly placed trays on the lower trays, facilitating the position adjustment of the lower trays that are not properly placed. The self-positioning mechanism 5 further comprises guide sliding columns 53 and clamping springs 54. The guide sliding columns 53 are transversely and slidingly connected in the sliding holes on the surface of the support shells 51. The clamping plates 52 are arranged between the end heads of the guide sliding columns 53 of the same support shell 51. The clamping plates 52 are located between the two support shells 51. The relative sliding of the guide sliding columns 53 and the support shells 51 provides guiding support for the movement of the clamping plates 52. The clamping springs 54 are arranged between the support shells 51 and the clamping plates 52. The clamping springs 54 are movably sleeved on the outer arc surface of the guide sliding columns 53 to elastically limit the clamping plates 52. The self-positioning mechanism 5 further comprises positioning rotating plates two 57 and torsion springs two 58. The positioning rotating plates two 57 are rotationally connected with the front and rear ends of the support frame 2 through rotating shafts two. The rotating shaft two outer arc surface of the positioning rotating plate two 57 is movably sleeved with a torsion spring two 58. One end of the torsion spring two 58 close to the horizontal center of the support frame 2 is fixedly connected with the positioning rotating plate two 57, and the other end of the torsion spring two 58 away from the horizontal center of the support frame 2 is fixedly connected with the support plate on the surface of the support frame 2. When the tray is not properly placed, the upward movement of the tray will apply a force to the inclined surface at the lower end of the positioning rotating plate two 57, pushing the positioning rotating plate two 57 to rotate and the torsion spring two 58 to twist. Under the torsion of the torsion spring two 58, a front-rear force is applied to the tray, pushing the tray to move to the correct position. For the properly placed tray, the positioning rotating plate two 57 does not apply a force to the tray.

[0022] The working principle of the tray rapid stacking device is as follows: in the process of full-automatic express delivery logistics, the tray used for transfer is conveyed to the lower end of the rack 1 along the guide rail 8 by using the conveying equipment; when the tray reaches the specified position, the electric push rod 9 is started by the control switch 10; the telescopic end of the electric push rod 9 drives the stacking top plate 4 to move upwards; the stacking top plate 4 is used to apply an upward force to the tray; the tray is pushed to move upwards; when the tray contacts the arc surface of the supporting plate 3, the force applied by the tray to the supporting plate 3 will overcome the elastic force of the reset spring 7, the supporting plate 3 is pushed to move horizontally, and power is provided for the continuous upward movement of the tray; when the upper surface of the supporting plate 3 is separated from the tray stack, the tray stack is stacked above the tray, and a new tray stack is formed; then the tray is continuously pushed to move upwards; when the height of the tray exceeds the height of the supporting plate 3, the supporting plate 3 is reset under the elastic force of the reset spring 7; then the stacking top plate 4 is reset by moving downwards; the tray stack contacts the upper surface of the supporting plate 3; the supporting plate 3 is used to provide support for the tray stack; the above operation is repeated, and the tray is rapidly stacked; in the stacking process, when the tray is not aligned, the upward movement of the tray will apply a force to the inclined surface at the lower end of the positioning turn plate one 55 and the inclined surface at the lower end of the positioning turn plate two 57, the positioning turn plate one 55 and the positioning turn plate two 57 are pushed to rotate, the torsion spring one 56 and the torsion spring two 58 are twisted, the tray is applied with a force under the torsion force of the torsion spring one 56 and the torsion spring two 58, and the tray is pushed to move to the accurate position; when the tray is aligned, the tray will enter between the two clamping plates 52 under the guidance of the positioning turn plate one 55; the clamping spring 54 is used to clamp the aligned tray left and right under the elastic force; the friction force between the clamping plate 52 and the aligned tray is used to reduce the pressure applied by the aligned tray to the lower tray, and the position of the lower tray which is not aligned is adjusted.

[0023] It is worth noting that the electric push rod 9 disclosed in the above embodiment can be freely configured according to the actual application scene; a DTL200 type electric reciprocating push rod is selected; and the control switch 10 is provided with a switch button corresponding to the electric push rod 9 and used for controlling the switch work of the electric push rod 9.
