DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-2In the embodiment of the utility model, a cell tray transplanting device includes a frame 1 and a transplanting manipulator 5 movably connected to the frame 1. The frame 1 is provided with a motion module, and the transplanting manipulator 5 is movably connected to the frame 1 through the motion module. In this embodiment, the motion module includes an X-axis linear motion module 2 fixedly connected to the frame 1, a Y-axis linear motion module 3 connected to the X-axis linear motion module 2, and a Z-axis linear motion module 4 connected to the Y-axis linear motion module 3. The manipulator 5 is connected to the Z-axis linear motion module 4, and the Z-axis linear motion module 4, the Y-axis linear motion module 3, and the Z-axis linear motion module 4 are arranged vertically to each other. The Z-axis linear motion module 4, the Y-axis linear motion module 3, and the Z-axis linear motion module 4 can drive the manipulator 5 to perform three-dimensional motion in space relative to the frame 1, so as to complete the grabbing and transplanting of the cell. In addition, the linear motion module can be one of a linear motor, a cylinder, an electric cylinder, a screw, etc.

[0021] A pallet transfer unit is provided under the transplanting robot 5, and the pallet transfer unit includes a connecting rod 8 and a first battery cell pallet fixture 12 and a second battery cell pallet fixture 15 arranged at the upper and lower ends of the connecting rod 8. In this embodiment, two connecting rods 8 are provided, and the two connecting rods 8 are arranged in parallel. The upper end of the connecting rod 8 is rotatably connected to the first pallet platform 10 through the first connecting shaft 11, and the first battery cell pallet fixture 12 is fixedly connected to the first pallet platform 10. The bottom end of the connecting rod 8 is rotatably connected to the second pallet platform 14 through the second connecting shaft 13, and the second battery cell pallet fixture 15 is fixedly connected to the second pallet platform 14. A cylinder 7 is arranged on one side of the frame 1, and the cylinder 7 is fixedly connected to the frame 1 through a mounting plate 6. The piston of the cylinder 7 is rotatably connected to the middle part of the connecting rod 8, so that the connecting rod 8 can be driven to move by the cylinder 7. In addition, the second pallet platform 14 in this embodiment is fixedly arranged with the frame 1, that is, when the piston of the cylinder 7 pushes and pulls the connecting rod 8, it pushes the connecting plate rod 8 to rotate around the second pallet platform 14, thereby making the first pallet platform 12 move away from the second pallet platform 14 or move to the top of the second pallet platform 14.

[0022] When the utility model is in use, first, the X-axis linear motion module 2 moves to drive the Y-axis linear motion module 3 and the Z-axis linear motion module 4 to move, the Y-axis linear motion module 3 drives the Z-axis linear motion module 4 to move, and the Z-axis linear motion module 4 can drive the manipulator 5 to move, and then the manipulator 5 can make three-dimensional movements in space, grab the battery tray to the tray platform inside the device, and the movement of the tray platform mainly depends on the swing of the connecting rod mechanism, in which the cylinder 7 is extended and retracted forward and backward to drive the two connecting rods 8 to swing in parallel. When the parallel expansion is carried out, the piston is extended and retracted, and the connecting rod 8 rotates to drive the first tray The platform 10 moves in the direction away from the second pallet platform 14, that is, the first pallet platform 10 and the second pallet platform 14 are staggered left and right, and then the robot 5 cooperates to grab and place the pallet on the platform. After the battery cells are placed on the two platforms, the connecting rod 8 is stacked upright under the drive of the piston, that is, the first pallet platform 10 rotates to the top of the second pallet platform 14, and then the robot of another device can come over and grab the battery cell pallets on the first pallet platform 10 and the second pallet platform 14 at the same time, and this reciprocating cycle is repeated until the battery core pallet is transferred to the equipment line of another assembly machine.
