Description

Technical Field

[0001] The utility model relates to the technical field of battery pack loading and unloading, in particular to an input and output mechanism of a battery pack conveyor line. Background Art

[0002] The battery pack of a new energy vehicle is relatively heavy. In order to prevent the battery pack from being damaged or deformed by a forklift, the battery pack is generally placed on a pallet for transportation. For example, patent CN109911507A discloses a roller conveyor line that can transport battery packs and pallets. However, in the prior art, placing the battery pack on a pallet and recycling the pallet is a very troublesome task, requiring manpower to carry out hoisting operations, which is not only inefficient but may also damage the battery pack. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides an input and output mechanism for a battery pack conveyor line that can achieve efficient pallet picking and placing operations and improve input and output efficiency.

[0004] Technical solution: To achieve the above purpose, the input and output mechanism of the battery pack conveyor line of the utility model includes:

[0005] A fixed seat body, which is fixedly installed relative to the ground;

[0006] A lifting frame body, which can move up and down relative to the fixed seat body, and the lifting movement is driven by a first driving mechanism; a plurality of first rollers are installed on the lifting frame body, and gaps are formed between the conveying rollers;

[0007] The lifting seat can move up and down relative to the lifting frame, and the lifting movement is driven by the second driving mechanism; the lifting seat has an upper convex part, and the top end of the upper convex part can extend from the vacant part.

[0008] During operation, the lifting frame is used to lift the battery tray, and there is a gap on the battery tray corresponding to the upper protrusion. The lifting seat is used to lift the battery pack. When it is necessary to input the battery pack to the battery pack conveyor line, the lifting frame obtains the battery tray from a lower position and lifts the battery tray to a position at the same height as the battery pack conveyor line, and the lifting seat rises relative to the lifting frame to a position where the top of the upper protrusion extends from the gap, the battery pack is conveyed to the top of the upper protrusion, and then the upper protrusion descends to place the battery pack on the battery tray. The first roller operates to output the battery tray and the battery pack thereon to the battery pack conveyor line.

[0009] When outputting the battery pack, the battery tray with the battery pack is conveyed to the input and output mechanism, and the lifting seat rises to push the battery pack away from the battery tray to facilitate output. After the battery pack is output, the lifting seat descends to a position where the upper protrusion is lower than the upper end of the lifting seat as a whole, and the lifting frame descends to the position of outputting the battery tray to output the battery tray, thereby completing the recycling of the tray.

[0010] Furthermore, a plurality of second rollers are installed on the upper end of the upper protrusion. By providing the second rollers, the horizontal input and output of the battery pack can be facilitated.

[0011] Furthermore, the number of the vacant portions is two, and correspondingly, the number of the upper protrusions is also two, "so that both sides of the battery pack can be supported to maintain the stability of lifting the battery pack."

[0012] Further, the first driving mechanism includes two groups of supporting driving components;

[0013] Each group of supporting driving components includes two slides and two connecting rods arranged corresponding to the two slides, each connecting rod is connected to the corresponding slide and the lifting frame; the two slides are connected to the same driving screw, and the two ends of the driving screw have left-handed threads and right-handed threads respectively, and the two slides are respectively fixed with left-handed nuts and right-handed nuts.

[0014] Furthermore, the two driving screws corresponding to the two groups of the support driving assemblies establish a synchronous relationship through a synchronization mechanism, and one of the driving screws is connected to a driving motor.

[0015] Furthermore, the second driving mechanism includes a plurality of guide rods fixed on the lifting seat, and a guide sleeve is fixed on the lifting frame and is slidably matched with the guide rods one by one; the second driving mechanism also includes a hydraulic cylinder installed on the lifting frame, and the hydraulic cylinder acts on the lifting seat.

[0016] Beneficial effects: The input and output mechanism of the battery pack conveyor line of the utility model has the following beneficial effects:

[0017] (1) The input and output mechanism of the battery pack conveyor line can easily add a battery tray to the bottom of the battery pack, and can easily remove the battery tray at the bottom of the battery pack for recycling. For very heavy electric vehicle battery packs, efficient pallet picking and placing operations can be achieved, thereby improving input and output efficiency.

[0018] (2) The first driving mechanism has a stable and reliable structure and can realize the smooth lifting of the lifting frame. Moreover, since the lead screw has a self-locking feature, the safety of the lifting can be ensured. BRIEF DESCRIPTION OF THE DRAWINGS
