[0034] When the battery cell 16 elevator provided by the utility model is in use, the servo motor 2 is used to drive the planetary rotating unit to rotate, and then the battery cell 16 on the low-position suction belt conveyor module 1 is transferred to the high-position suction belt conveyor module 13 through the suction bearing fork 12 on one side of the planetary rotating unit, so as to achieve docking when there is a height difference between the front and rear stations, and by arranging a plurality of suction bearing forks 12 in a circular array on the mounting frame 18, the rotation of the planetary rotating unit can be coordinated to achieve synchronization of taking and releasing materials, the structure is simple and the cost is low, but the efficiency is improved compared with the existing robot arm; wherein the mounting frame 18 is preferably a cross-shaped structure, and the suction bearing forks 12 are preferably four.

[0035] like Figure 2 As shown, the reducer 3, the coupling 5 and the rotating shaft 7 are axially fixedly connected in sequence between the motor output shaft and the mounting frame 18; the reducer 3 is fixedly connected to the output shaft of the servo motor 2, and the rotating shaft 7 is fixedly connected to the center of the mounting frame 18; the coupling 5 is used to connect the output shaft of the reducer 3 and the rotating shaft 7; the top of the motor mounting seat 17 is also fixedly connected to the first bearing seat 4 and the second bearing seat 6; the rotating shaft 7 is rotatably connected in the second bearing seat 6, and the output shaft of the reducer 3 is rotatably connected in the first bearing seat 4.

[0036] The reducer 3 and coupling 5 in the battery cell 16 lifting machine provided by the utility model belong to the prior art, and the first bearing seat 4 and the second bearing seat 6 are used to connect the output shaft of the reducer 3 and the rotating shaft 7; wherein, when the servo motor 2 is started, the mounting frame 18 can be driven to rotate through the reducer 3, the coupling 5 and the rotating shaft 7 in sequence.

[0037] like Figure 2 As shown, the mounting frame 18 is rotatably connected to a plurality of planetary secondary synchronous wheels 10 on a side away from the air intake bearing fork 12 , and the planetary secondary synchronous wheels 10 are coaxial with the air intake bearing fork 12 ; the plurality of planetary secondary synchronous wheels 10 are driven via a synchronous belt 11 .

[0038] The utility model provides a battery cell 16 elevator with multiple planetary secondary synchronous wheels 10, which are driven by a synchronous belt 11. During the rotation of the mounting frame 18, the angles between the multiple suction load forks 12 and the horizontal plane are always kept consistent. Here, preferably, the multiple suction load forks 12 are parallel to the horizontal plane, so as to realize the horizontal transfer of the battery cell 16 from the low-position suction belt conveyor module 1 to the high-position suction belt conveyor module, wherein there are preferably four planetary secondary synchronous wheels 10.

[0039] like Figure 2As shown, the second bearing seat 6 is rotatably connected to the side of the mounting frame 18, and the sun synchronous wheel 8 is fixedly connected to the rotating shaft 7; one of the planetary secondary synchronous wheels 10 is coaxially fixedly connected to the planetary primary synchronous wheel 9, and the planetary primary synchronous wheel 9 and the sun synchronous wheel 8 are driven by another synchronous belt 11.

[0040] When the rotating shaft 7 in the battery cell 16 lifting machine provided by the utility model rotates, it can synchronously drive the sun synchronous wheel 8 to rotate, and use another synchronous belt 11 to drive the planetary first-stage synchronous wheel 9, and then use the planetary first-stage synchronous wheel 9 to drive one of the planetary second-stage synchronous wheels 10 to rotate, so that during the lifting stage of the battery cell 16, multiple suction load forks 12 can be kept parallel to the horizontal plane at all times.

[0041] like Figure 1 to Figure 2 As shown, a support seat 15 is fixedly connected to the other side of the top of the lower frame 14, and the support seat 15 is located between the low-position suction belt conveyor module 1 and the high-position suction belt conveyor module 13; the support seat 15 is configured as a P-shaped structure, and the mounting frame 18 is rotatably connected to the support seat 15.

[0042] The support seat 15 in the battery cell 16 elevator provided by the utility model is used to connect the mounting frame 18 to maintain the stability of the mounting frame 18 when rotating, wherein the mounting frame 18 is used to separate the low-position suction belt conveyor module 1 and the high-position suction belt conveyor module 13.

[0045] Working principle: The lifting mechanism in the prior art has a complex structure, high cost, and low efficiency. When there is a height difference between the stations of the two steps, which can be simply understood as a height difference between the two conveyor belts, the robot arm can only realize picking or placing in a single way, and cannot simultaneously solve the problem of docking and synchronization of picking and placing materials when there is a height difference between the front and rear stations, thereby failing to improve the efficiency of the transfer and lifting of the battery cells 16.

[0046] When the battery cell 16 elevator provided by the utility model is in use, the servo motor 2 is used to drive the planetary rotating unit to rotate, and then the battery cell 16 on the low-position suction belt conveyor module 1 is transferred to the high-position suction belt conveyor module 13 through the suction bearing fork 12 on one side of the planetary rotating unit, so as to achieve docking when there is a height difference between the front and rear stations, and by arranging a plurality of suction bearing forks 12 in an annular array on the mounting frame 18, the rotation of the planetary rotating unit can be coordinated to achieve synchronization of taking and releasing materials, the structure is simple and the cost is low, but the efficiency is improved compared with the existing mechanical arm ; The mounting frame 18 is preferably a cross-shaped structure, and the air suction bearing forks 12 are preferably four; multiple planetary secondary synchronous wheels 10 are provided, and a synchronous belt 11 is used to drive multiple planetary secondary synchronous wheels 10, so that during the rotation of the mounting frame 18, the angles between the multiple air suction bearing forks 12 and the horizontal plane can always be kept consistent. Here, it is preferred that the multiple air suction bearing forks 12 are parallel to the horizontal plane, so as to realize the horizontal transfer of the battery cell 16 from the low-position air suction belt conveyor module 1 to the high-position air suction belt conveyor module, wherein the planetary secondary synchronous wheels 10 are preferably four;

[0047] Among them, when the rotating shaft 7 rotates, it can synchronously drive the sun synchronous wheel 8 to rotate, and use another synchronous belt 11 to drive the planetary first-stage synchronous wheel 9, and then use the planetary first-stage synchronous wheel 9 to drive one of the planetary second-stage synchronous wheels 10 to rotate, so that during the lifting stage of the battery cell 16, multiple suction load forks 12 can be kept parallel to the horizontal plane at all times.
