[0035] Embodiment:

[0036] As shown in the attached Figure 1 to the attached Figure 6 figure:

[0037] The present utility model provides a battery assembly device for a lithium battery pack, including:

[0038] a battery sorting mechanism 1, a battery transfer mechanism 2, a first flat belt conveyor 3, a clamping mechanism 5, and a blanking mechanism 6;

[0039] The battery transfer mechanism 2 includes a robotic arm 21, a shunt box 23 installed on the robotic arm 21, a plurality of suction cups 22 arranged in an array and communicating with the shunt box 23, an air pipe 24 with one end communicating with the shunt box 23, and a vacuum pump 25 communicating with the other end of the air pipe 24;

[0040] The battery sorting mechanism 1 places a plurality of batteries 7, and the battery sorting mechanism 1 is used to arrange the batteries in an array;

[0041] The feeding end of the first flat belt conveyor 3 continuously places the battery pack bottom frame 4, and the robotic arm 21 can adsorb the batteries 7 sorted by the battery sorting mechanism 1 and insert them into the battery holes of the battery pack bottom frame 4;

[0042] The clamping mechanism 5 is arranged above the first flat belt conveyor 3. The clamping mechanism 5 can clamp the battery pack bottom frame 4 with the inserted battery 7. A chamfer is provided on the outer circle of the upper part of the battery hole of the battery pack bottom frame 4 to facilitate the insertion of the battery by the robotic arm 21 into the battery hole;

[0043] The blanking mechanism 6 is located above the clamping mechanism 5. The blanking mechanism 6 can place the battery pack top frame 8 downward. A chamfer is provided at the bottom of the battery hole of the battery pack top frame 8 to facilitate the clamping of the battery pack top frame 8 onto the battery 7. The diameter of the battery hole of the battery pack top frame 8 is slightly larger than the diameter of the battery 7 to facilitate the clamping of the battery pack top frame 8 onto the battery 7. Multiple battery pack top frames 8 can be set according to specific circumstances.

[0044] In this embodiment, the cylindrical batteries are first arranged into an array by the battery arrangement mechanism 1, and then the cylindrical batteries arranged in the array are adsorbed by the suction cup 22 of the robot arm 21, and then clamped into the battery pack top frame 8 on the flat belt conveyor 3. The battery pack top frame 8 continues to move with the flat belt conveyor 3 to the bottom of the unloading mechanism 6, and the battery pack bottom frame 4 is clamped by the clamping mechanisms 5 on both sides. Then a battery pack top frame 8 falls from the unloading mechanism 6, thereby realizing automated and rapid production of small battery modules.

[0045] The battery sorting mechanism 1 is provided with a flat belt conveyor 11, and limit bars 12 are provided on both sides of the flat belt conveyor 11, and a plurality of longitudinal limit bars 13 are arranged side by side along the transmission direction of the flat belt conveyor 11, and a plurality of transverse limit bars 14 are arranged in an array at the discharge end of the flat belt conveyor 11, and a second telescopic mechanism 15 is installed on the transverse limit bar 14. The battery sorting mechanism 1 sorts the batteries, so that the batteries are limited to a specific array arrangement by the plurality of longitudinal limit bars 13 and the plurality of transverse limit bars 14 before adsorption.

[0046] There are two groups of clamping mechanisms 5, which are symmetrically distributed on both sides of the flat belt conveyor 3. The clamping mechanisms 5 include clamping claws 51 and first telescopic members 53 that are transmission-connected to the clamping claws 51. The clamping mechanisms 5 further limit the position of the battery pack bottom frame 4, which is convenient for the subsequent placement of the battery pack top frame 8.

[0047] A stripping plate 52 is provided at the bottom of the clamping claw 51. The stripping plate 52 plays a buffering role for the battery pack top frame 8 to fall.

[0048] The material unloading mechanism 6 includes a material guide plate 61, a motor 62 fixedly connected to the material guide plate 61, a material unloading member 63 drivingly connected to the motor 62, a material unloading plate 64 arranged at the bottom of the material guide plate 61, and a third telescopic member 65 fixedly connected to the material guide plate 61, and the third telescopic member 65 drivingly connected to the material unloading plate 64. In order to realize the purpose of unloading the single battery pack top frame 8 one by one.

[0050] The guide plate 61 includes two symmetrically distributed "凵"-shaped plates. The arrangement of the two "凵"-shaped plates forms a viewing window in the middle thereof for easy observation, thereby facilitating the user to obtain the usage status of the battery pack top frame 8.

[0051] The material feeding part 63 is made of rubber. Using rubber material enables the material feeding plate 63 to have a relatively large friction coefficient and a better elastic coefficient, so that the battery pack top frame 8 is not prone to sliding, and at the same time, it avoids the problem of rigid impact between the material feeding part 63 and the material feeding plate 63 caused by the control accuracy problem of the motor 62.

[0052] A bracket 9 is also provided, and the flat belt conveyor 3, the clamping mechanism 5 and the blanking mechanism 6 are all installed on the bracket 9. The bracket 9 ensures the stable operation of the flat belt conveyor 3, the clamping mechanism 5 and the blanking mechanism 6.

[0053] The specific usage mode and function of this embodiment:

[0054] When the present utility model is in use, first place the battery 7 on the battery sorting mechanism 1. With the transportation of the flat belt conveyor 11, the batteries gradually gather in the gaps between multiple longitudinal limiting strips 13. When a certain amount is gathered, the transverse limiting strips 14 are sequentially inserted through from the discharging side between multiple side-by-side batteries 7. After all the transverse limiting strips 14 and the longitudinal limiting strips 13 are cross-distributed, the batteries can be neatly arranged. Then, the manipulator 21 of the battery transfer mechanism 2 moves the suction cup 22 to directly above all the batteries 7, and then moves downwards so that the suction cup 22 adsorbs the corresponding battery 7. Then the manipulator 21 extracts this group of batteries 7 and moves them above the battery pack bottom frame 4. At this time, the flat belt conveyor 3 is in a stopped state. After this group of batteries 7 is inserted into the battery pack bottom frame 4, start the flat belt conveyor 3 to move the battery pack bottom frame 4 with the inserted batteries 7 to directly below the blanking mechanism 6. Then, the clamping mechanisms 5 on both sides play a role in clamping and positioning the battery pack bottom frame 4. Then, the third telescopic member 65 pulls the blanking plate 64 outwards, so that the lowermost battery pack top frame 8 falls to the upper part of the battery pack bottom frame 4. The third telescopic member 65 pushes the blanking plate 64 inwards, and then the material feeding part 63 rotates outwards by a certain angle, so that the battery pack bottom frame 4 clamped by the material feeding part 63 falls onto the upper surface of the blanking plate 64. Then the material feeding part 63 rotates back by a certain angle and contacts the battery pack bottom frame 4. After that, the flat belt conveyor 3 drives the battery pack bottom frame 4 to move backwards.

Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.
