Description

Technical Field

[0001] This utility model belongs to the field of battery cell processing robot technology, and in particular relates to a robot stacking device for adaptive gripping of battery cells. Background Technology

[0002] The adaptive gripping robot stacking device for battery cells is an automated device designed specifically for lithium battery production. Through flexible gripping technology and intelligent control system, it can achieve adaptive gripping and high-precision stacking of battery cells of different sizes and states.

[0003] Currently available robotic stacking devices for adaptive gripping of battery cells have the following problems when applied:

[0004] 1. Traditional battery cell adaptive gripping robot stacking devices typically use gripping structures made of metal. Although the gripping force can be automatically adjusted according to the battery cell thickness or deformation, if the numerical force control is not precise enough, it is easy to squeeze or deform the battery cell, resulting in unnecessary waste. Therefore, no wear-resistant structure is installed during use.

[0005] 2. In most applications of adaptive gripping robot stacking devices for battery cells, the bottom of the robotic arm is often fastened to the ground. Once fastened, if an error is found in the angle of the robotic arm, it can only be reinstalled, making angle adjustment inconvenient during application. Utility Model Content

[0029] like Figure 1-5 As shown, this utility model discloses a robot stacking device for adaptive gripping of battery cells, comprising an arm 4 and a gripper 5. The gripper 5 is located at the top of the arm 4, and a robotic arm 3 is movably connected to the side of the arm 4. The installation of the arm 4 facilitates the connection between the robotic arm 3 and the gripper 5. The bottom of the robotic arm 3 is movably connected to a host 2, and a base plate 1 is located at the bottom of the host 2. A rubber plate 6 is located on the inner side of the gripper 5, and an elastic sleeve 7 is located on the side of the rubber plate 6. A fixing frame 10 is located outside the elastic sleeve 7, and a fastening screw 12 is embedded inside the fixing frame 10. A threaded hole 13 is opened on the outside of the gripper 5. The fastening screw 12 is threadedly connected to the threaded hole 13. A rubber plate 6 is provided on the outside of the gripper 5, and an elastic sleeve 7 and a fixing frame 10 are provided on the side of the rubber plate 6. The fastening screw 12 is embedded inside the fixing frame 10. The operator takes out the rubber structure, first installs the elastic sleeve 7 and the rubber plate 6 on the outside of the robotic arm 3, and then tightens the fastening screw 12 to install it on the outside of the gripper 5. In this way, the rubber structure can be installed on the outside of the gripper 5 to avoid squeezing and damaging the battery cell.

[0030] The bottom of the base plate 1 is provided with a base 14, the top of the base 14 is provided with a threaded post 19, and the top of the base plate 1 is provided with an arc-shaped groove 21. The threaded post 19 passes through the interior of the arc-shaped groove 21, and the external thread of the threaded post 19 is connected to a locking nut 20. The top of the base plate 1 is provided with a ball-shaped tie rod 22, which is distributed in a ring. By installing the base 14 at the bottom of the base plate 1, and providing the threaded post 19 and locking nut 20 at the top of the base 14, and the arc-shaped groove 21 at the top of the base plate 1, if the position and angle of the installed robotic arm 3 are found to be incorrect, the operator first reverses the rotation of the threaded post 19. Then, by holding the ball-shaped tie rod 22 and rotating the base plate 1, the threaded post 19 is rotated inside the arc-shaped groove 21. After rotating to the appropriate angle, the operator directly tightens the external locking nut 20 to fix it.

[0031] The rubber sheet 6 has a locking block 8 on its outside and a locking groove 9 on the inside of the gripper 5. The locking block 8 is embedded in the inside of the locking groove 9. By providing the locking block 8 and the locking groove 9, it is convenient to initially splice the rubber sheet 6 and the gripper 5.

[0032] The external threaded seat 11 of the fixing frame 10 is connected to the fastening screw 12 by the external thread of the threaded seat 11. Because the threaded seat 11 is provided, it is convenient to connect the fastening screw 12 to the fixing frame 10 by thread.

[0033] The base 14 is provided with an external mounting plate 17, which is in the form of a ring. The top of the mounting plate 17 has a mounting hole 18. Because of the mounting plate 17 and the mounting hole 18, it is convenient to install the base 14 on the ground with fasteners.

[0034] The bottom of the base plate 1 is provided with a positioning block 15, and the top of the base 14 is provided with a positioning groove 16. The positioning block 15 is embedded in the positioning groove 16. Because of the positioning block 15 and the positioning groove 16, it is convenient to perform preliminary splicing of the base plate 1 and the base 14.

[0035] The working principle of this adaptive gripping robot stacking device for battery cells is as follows: When using this robot, the robot body first needs to be installed. The operator removes the fasteners that pass through the mounting holes 18 inside the mounting plate 17 and directly installs the base 14 on the ground, thus fixing the robot's position. However, for convenient and quick position adjustment, it is not necessary to dismantle the entire installation structure. The base 14 is installed at the bottom of the base plate 1, and a threaded post 19 and a locking nut 20 are provided on the top of the base 14. An arc-shaped groove 21 is opened on the top of the base plate 1, and a ball joint 22 is installed on the top of the base plate 1. When the angle of the installed robotic arm 3 is found to be incorrect, the operator directly reverses the threaded post 19 to adjust the required angle. By holding the ball joint 22 and rotating the base plate 1, the positioning block 15 rotates inside the positioning groove 16, causing the threaded post 19 to rotate inside the arc-shaped groove 21. After rotating to the appropriate angle, the operator directly tightens the external locking nut 20 to fix it, thus completing the angle adjustment. Secondly, in order to reduce the damage caused by the rigid gripper 5 when clamping the battery cell, a rubber plate 6 is provided on the outside of the gripper 5, and an elastic sleeve 7 and a fixing frame 10 are provided on the side of the rubber plate 6. The fixing frame 10 has a threaded seat 11 on the outside, and a fastening screw 12 is threadedly connected inside the threaded seat 11. Next, a locking block 8 is provided on the inside of the rubber plate 6. First, the elastic sleeve 7 and the rubber plate 6 are initially installed on the outside of the robotic arm 3, and the locking block 8 is embedded in the slot 9. Then, the fastening screw 12 is tightened to connect with the threaded slot, thus installing the rubber structure on the outside of the gripper 5. Finally, when using the gripper 5, the rubber structure installed on its inside will directly contact the battery cell. When clamping the battery cell, the clamping force can be automatically adjusted according to the thickness or deformation of the battery cell to avoid squeezing and damaging the battery cell.
