Detailed implementation mode

[0023] The loading and unloading device for trays provided in this embodiment is as Figures 1-3 shown, and specifically includes a displacement mechanism, a first conveying mechanism 10 and a second conveying mechanism 20. The first conveying mechanism 10 and the second conveying mechanism 20 are horizontally and parallelly arranged, and both are provided with two conveyor belts 60 for carrying and transporting the trays 70. The conveying directions of the conveyor belts 60 on the first conveying mechanism 10 and the second conveying mechanism 20 are opposite. The displacement mechanism has two displacement units 30 corresponding to the first conveying mechanism 10 and the second conveying mechanism 20 respectively. Each displacement unit 30 includes a pallet unit that displaces in a preset direction, and the pallet unit is staggeredly arranged with the conveyor belt 60 in the preset direction. When the pallet unit displaces in the preset direction, it carries the tray 70 on the conveying mechanism or places the unloaded tray 70 so that it is carried by the conveying mechanism. The displacement in the preset direction specifically refers to the up and down displacement in the vertical direction in this embodiment. The pallet unit can move repeatedly above and below the conveyor belt 60. In some other implementation modes, the displacement in the preset direction can also specifically refer to a linear displacement inclined at a certain angle to the horizontal plane.

[0024] In this embodiment, each pallet unit is composed of a plurality of parallel pallets 33 connected to each other, so that there are gaps between the pallets 33 in each part, achieving a staggered distribution of the pallet unit and the conveyor belt 60 in the vertical direction. In addition, the pallet unit further includes a displacement track 31 and a displacement slider 32 slidably connected thereto, and the displacement slider 32 is connected to the pallet unit to drive the pallet unit to lift and lower. A plurality of parallel limit plates 34 are installed on both sides of the pallet unit, and there is a limit gap between the limit plates 34. A limit roller 35 adapted to the limit gap is connected to the pallet 33, so that when the pallet unit displaces in the preset direction, the limit roller 35 moves in the limit gap, playing a role in limiting and stabilizing the whole device when the pallet unit lifts and lowers.

[0025] See Figure 1 and Figure 3, the loading and unloading device of this embodiment further includes a tray transfer mechanism disposed above the displacement mechanism. The tray transfer mechanism includes a transverse rail 41 and a vertical rail 42 that is horizontally slidably connected thereto. A suction tray 43 for sucking the tray 70 is slidably connected to the vertical rail 42. A plurality of vacuum suction cups are distributed at the bottom of the suction tray 43 to achieve suction on the top surface of the tray 70. The transverse rail 41 is connected to the mounting bracket 44. When the tray transfer mechanism operates, the suction tray 43 moves up and down in the vertical direction and moves horizontally, enabling the transfer of the tray 70 between the two displacement units 30. It should be noted that in this embodiment, the mounting bracket 44 of the tray transfer mechanism can be connected to the first conveying mechanism 10, the second conveying mechanism 20 or the displacement unit 30 through a fixed connecting member, or can be erected on the ground in other ways such as through columns. As long as the position of the transverse rail 41 is relatively fixed with respect to the displacement unit 30, this embodiment only gives an example of the layout position of the tray transfer mechanism.

[0026] As Figure 2 shown, a plurality of groups of photoelectric sensors 51 are provided on both the first conveying mechanism 10 and the second conveying mechanism 20. In each group of photoelectric sensors 51, one is used to emit a sensing light beam 52, and the other is used to receive the sensing light beam 52 to achieve the function of detecting the arrival of the tray 70.

[0027] As Figures 4-5 shown, the loading and unloading device of this embodiment further includes a tray 70 carried by the conveyor belt 60 or the pallet unit. The top surface of the tray 70 has a material groove for holding batteries. The bottom surface of the tray 70 has an edge adapted to its top surface, enabling a plurality of trays 70 to be stacked one by one in the vertical direction to form Figure 6 the shown tray unit for loading and unloading, improving work efficiency.

[0028] The following describes one of the usage methods of the loading and unloading device of the present application: Place a tray unit filled with batteries on the first conveying mechanism 10 (that is, multiple trays 70 are stacked up and down after being filled with batteries), stop when approaching the end, the pallet unit adapted to the first conveying mechanism 10 rises, bears the tray unit on the conveyor belt 60 of the first conveying mechanism 10 and stops at a predetermined height. At this time, the batteries in the uppermost tray 70 are extracted by a multi-axis manipulator (not shown in the figure) or manually. After the extraction is completed, the empty tray 70 is adsorbed to the pallet unit adapted to the second conveying mechanism 20 by the suction cup 43. At the same time, the pallet unit adapted to the first conveying mechanism 10 rises one grid, and the pallet unit adapted to the second conveying mechanism 20 descends one grid. Repeating this way can complete the extraction of the batteries in one tray unit. The empty tray units are stacked on the pallet unit adapted to the second conveying mechanism 20. At this time, the pallet unit adapted to the second conveying mechanism 20 descends, places the empty tray units on the conveyor belt 60 of the second conveying mechanism 20 and conveys them back, and a closed loop of the loading process of one tray unit can be completed; while the unloading process is the opposite. The conveying mechanism provides empty tray units for placing batteries. After the tray units are filled, they are stacked and conveyed by another conveying mechanism, and a closed loop of the unloading process can also be formed.

[0029] In addition to the above embodiments, the present utility model can also have other implementation manners; all technical solutions formed by equivalent replacement or equivalent transformation fall within the protection scope required by the present utility model.
