Description

Technical Field

[0001] The utility model belongs to the technical field of battery processing equipment, in particular to a battery core shell transport device. Background Art

[0002] Lithium-ion batteries usually include a shell and a cell arranged in the shell. During the processing of lithium-ion batteries, the cell needs to be transported and placed in the shell. At present, there are two ways to put the cell into the shell: inclined shell and vertical shell. When inclined shell is adopted, the gripper of a six-axis robot is usually used to clamp one end of the cell, and then the other end of the cell is tilted and extended into the bottom of the shell, and finally the gripper is opened and extracted, so that the cell falls into the shell completely. In the process of opening and withdrawing the gripper, the gripper is in direct contact with the surface of the cell. The gripper is easy to scratch the cell during the opening and withdrawal process, affecting the quality of the battery. At the same time, in the process of opening and withdrawing the gripper, the cell is also affected by the friction of the gripper, and will move a certain distance with the gripper, resulting in the relative position between the cell and the shell being offset, resulting in inaccurate positioning of the cell, affecting the subsequent assembly of the battery. When vertical shell is adopted, the cell is usually held by a mechanical gripper and moved to the top of the shell, and then the gripper is opened, so that the cell falls vertically into the shell under the action of gravity. During the opening process of the mechanical claws, the claws slide relative to the surface of the battery cell, causing friction and easily scratching the surface of the battery cell. At the same time, when the claws are opened, the battery cell is in a free fall state, and it is difficult to ensure that the battery cell is properly inserted into the shell, affecting the subsequent assembly of the battery. At the same time, the battery cell is also at risk of damage after falling. Utility Model Content

[0030] See also Figures 1 to 8 The present embodiment provides a battery cell shell-entering and transporting device, comprising a load-bearing beam 1, a connecting member 2 arranged on the load-bearing beam 1, a shell-entering assembly 3 and a lifting assembly 4. The shell-entering assembly 3 comprises a vertical driving mechanism 10 and an adsorption mechanism arranged on the vertical driving mechanism 10, the vertical driving mechanism 10 is arranged on the connecting member 2, and drives the adsorption mechanism to reciprocate in the vertical direction. The adsorption mechanism can adsorb the battery cell 16, and the adsorbed battery cell 16 can move up and down with the adsorption mechanism under the action of the vertical driving mechanism 10. When the battery cell is put into the shell, the battery cell 16 is driven to descend, thereby constraining the descending trajectory and descending speed of the battery cell 16, and preventing the battery cell 16 from free falling and being damaged or positionally shifted.

[0031] The lifting assembly 4 includes a bearing member 5 and a lifting member 6, and the lifting member 6 includes a connecting portion 7 and a lifting cantilever 8. In this embodiment, the connecting portion 7 is a plate-shaped bearing member 5 connected to the connecting member 2, and the connecting portion 7 is arranged on the bearing member 5 in a horizontally movable manner. The lifting cantilever 8 is connected to the connecting portion 7 and extends along the moving direction of the connecting portion 7. In this embodiment, the connecting portion 7 is a plate-shaped portion perpendicular to the extending direction of the lifting cantilever 8.

[0032] The lifting arm 8 is used to lift the battery cell 16. When the lifting arm 8 moves to the bottom of the battery cell 16, the lifting arm 8 can lift the battery cell 16 adsorbed by the adsorption mechanism, thereby providing additional support for the battery cell 16 and reducing the probability of accidental drop of the battery cell 16. When the lifting arm 8 leaves the bottom of the battery cell 16, the bottom of the battery cell 16 is suspended in the air, and the vertical drive mechanism 10 can lower the battery cell 16 in the vertical direction to achieve the entry of the battery cell 16 into the shell.

[0033] Specifically, Figure 1 , Figure 7 and Figure 8 As shown, in this embodiment, the load-bearing beam 1 extends in the horizontal direction and is suspended, the connecting member 2 is movably arranged on the load-bearing beam 1 along the extension direction of the load-bearing beam 1, the vertical drive mechanism 10 is located below the connecting member 2, and the adsorption mechanism is located below the vertical drive mechanism 10. The load-bearing beam 1 is suspended, which increases the space below the load-bearing beam 1, is conducive to the placement of the battery cell 16 shell 17, and is also conducive to the layout of the lifting component 4 and the shell component 3. The load-bearing beam 1 extends in the horizontal direction, and the connecting member 2 is movably arranged on the load-bearing beam 1 along the extension direction of the load-bearing beam 1, so as to realize the displacement of the battery cell 16 after grasping, which is conducive to increasing the handling range of the battery cell shell handling device and improving the overall application range of the battery cell shell handling device. A driving mechanism such as a servo motor can be set on the connecting member 2 to drive it to achieve movement on the load-bearing beam 1.

[0034] As shown in FIG. 4 , there may be multiple lifting cantilevers 8 connected to the same connection portion 7, and the multiple lifting cantilevers 8 are arranged in sequence and spaced apart from each other, and the arrangement direction of the multiple lifting cantilevers 8 is perpendicular to the extension direction and the vertical direction of the load-bearing beam 1. The lifting cantilevers 8 are spaced apart from each other, and the overall weight of the lifting member 6 can be reduced while maintaining the lifting range, and the material cost of the lifting member 6 can also be reduced.

[0035] When the lifting arm 8 extends under the battery cell 16 or is pulled out from under the battery cell 16, there is a relative distance between the lifting arm 8 and the battery cell 16. In this embodiment, a protruding roller 9 is provided on the side of the lifting arm 8 for cooperating with the battery cell 16. When the lifting arm 8 lifts the battery cell 16, the battery cell 16 is supported on the roller 9. Compared with the battery cell 16 being directly placed on the lifting arm 8, the roller 9 can convert the sliding friction between the lifting arm 8 and the battery cell 16 into rolling friction, so as to reduce the movement resistance between the battery cell 16 and the lifting arm 8, thereby reducing the probability of the lifting arm 8 scratching the surface of the battery cell 16. In this embodiment, the rotation axis of the roller 9 is arranged in the horizontal direction and is perpendicular to the extension direction of the lifting arm 8, so as to reduce the movement resistance between the battery cell 16 and the lifting arm 8 in the extension direction of the lifting arm 8. In some embodiments, the roller 9 can also be a universal ball, so as to reduce the movement resistance between the battery cell 16 and the lifting arm 8 in each horizontal direction. In this embodiment, there are multiple rollers 9, and the multiple rollers 9 are arranged in sequence along the extension direction of the lifting cantilever 8. Increasing the number of rollers 9 is beneficial to increasing the lifting area of ​​the battery cell 16. When the weight of the battery cell 16 remains unchanged, the pressure exerted by a single roller 9 on the battery cell 16 can be reduced, thereby avoiding compression and deformation of the surface of the battery cell 16.

[0036] like Figure 3 As shown, two mutually parallel bearing rails 14 are arranged on the bearing member 5, and there is a spacing between the two bearing rails 14, and both extend along the extension direction of the bearing beam 1, and the connecting portion 7 of the lifting member 6 is slidably arranged on the two bearing rails 14. The bearing rails 14 can guide the lifting member 6 and improve the movement accuracy of the lifting member 6. There are two bearing rails 14, which can share the weight of the lifting member 6 and improve the service life of the bearing rails 14. The two bearing rails 14 are arranged at a spacing from each other, which is beneficial to increase the stability of the lifting member 6 and reduce the shaking of the lifting member 6.

[0037] In this embodiment, a slider 15 is provided on the bearing guide rail 14 , and the lifting member 6 is provided on the slider 15 , which is beneficial to reducing the wear of the lifting member 6 and improving the service life of the equipment.

[0038] like Figure 2 , Figure 7 and Figure 8As shown, in this embodiment, there are two lifting members 6, and the two lifting members 6 are respectively located on opposite sides of the adsorption mechanism, and the cantilever ends of the two lifting members 6 lifting cantilevers 8 are arranged close to each other. During the movement of the bracket member, the two lifting members 6 approach each other or move away from each other on the bearing member 5. When the two lifting members 6 move away from each other, the lifting cantilever 8 is gradually pulled out from the bottom of the battery cell 16, and the lifting assembly 4 is gradually opened to release the battery cell 16 supported on the lifting cantilever 8. When the two lifting members 6 approach each other, the lifting cantilever 8 gradually extends under the bottom of the battery cell 16, and the lifting assembly 4 is gradually closed to lift the battery cell 16.

[0039] like Figure 5 , Figure 6 As shown, in this embodiment, the vertical drive mechanism 10 includes a fixed part and a moving part, the fixed part is connected to the connecting member, the adsorption mechanism is arranged on the moving part, and the fixed part drives the moving part to move. The vertical drive mechanism 10 can be a linear drive mechanism such as a hydraulic cylinder and a linear motor. In this embodiment, the vertical drive mechanism 10 is a cylinder, which has the advantages of small size, light weight, simple structure, high power, high reliability, and rapid response, and is suitable for industrial applications.

[0040] like Figure 5 , Figure 6 As shown, in this embodiment, the adsorption mechanism is an adsorption tray, including a tray body 11 and a negative pressure suction nozzle 12 disposed on the tray body 11, the negative pressure suction nozzle 12 is located on one side of the tray body 11, and the vertical drive mechanism 10 is connected to the side of the tray body 11 away from the negative pressure suction nozzle 12. The tray body 11 supports the negative pressure suction nozzle 12 disposed thereon, and the negative pressure suction nozzle 12 is connected to the negative pressure device, and contacts and fits with the battery cell 16, thereby adsorbing the battery cell 16.

[0041] There can be multiple negative pressure nozzles 12 to increase the suction force on the battery cell 16 and ensure reliable suction. Multiple negative pressure nozzles 12 are evenly arranged on the tray 11 so that each negative pressure nozzle 12 is subjected to a balanced force. The arrangement of the negative pressure nozzles 12 can be reasonably set according to the shape of the battery cell 16. Figure 6 As shown, in this embodiment, a plurality of negative pressure nozzles 12 are arranged in a row to match and absorb rectangular battery cells 16. In this embodiment, a weight reduction hole 13 is also opened on the tray body 11 to reduce the weight of the tray body 11 and reduce the energy consumption of the vertical motion mechanism.

[0042] like Figure 7As shown, when the shell entry and handling device absorbs the battery cell 16, the connecting member 2 drives the shell entry assembly 3 and the lifting assembly 4 to move to one end of the load-bearing beam 1, so that the adsorption mechanism of the shell entry assembly 3 is aligned with the battery cell 16 to be shelled. The two lifting members 6 of the lifting assembly 4 move away from each other until a channel for the battery cell 16 to pass through is formed. The vertical drive mechanism 10 drives the adsorption mechanism to move downward, so that the negative pressure suction nozzle 12 of the adsorption mechanism fits the upper surface of the battery cell 16, and the negative pressure device is turned on. The negative pressure suction nozzle 12 generates negative pressure to absorb the battery cell 16. After the adsorption mechanism absorbs the battery cell 16, the vertical drive mechanism 10 drives the adsorption mechanism and the battery cell 16 adsorbed on the adsorption mechanism to move upward until the lifting cantilever 8 of the lifting member 6 is completely located below the battery cell 16. The two lifting members 6 of the lifting assembly 4 move toward each other, so that the lifting cantilevers 8 of the two lifting members 6 extend under the battery cell 16 , and the lifting cantilevers 8 act on the lower surface of the battery cell 16 , thereby completing the absorption of the battery cell 16 .

[0043] After the shell-entering and handling device absorbs the battery cell 16, the connecting member 2 drives the shell-entering assembly 3 and the lifting assembly 4 to move to the other end of the load-bearing beam 1, so that the battery cell 16 on the adsorption mechanism is aligned with the opening 18 of the shell 17 to be enclosed, and the two lifting members 6 of the lifting assembly 4 move away from each other to re-form a passage for the battery cell 16 to pass through. The vertical drive mechanism 10 drives the adsorption mechanism and the battery cell 16 adsorbed on the adsorption mechanism to move downward until the battery cell 16 enters the opening 18 of the shell 17, and the negative pressure suction nozzle 12 cuts off the connection with the negative pressure device, releases the battery cell 16, and completes the shell-entering of the battery cell 16.

[0044] In summary, in the shell entry and handling device of the present embodiment, when the lifting cantilever 8 moves to the bottom of the battery cell 16, the lifting cantilever 8 can lift the battery cell 16 adsorbed by the adsorption mechanism, and further provide additional support to the battery cell 16, thereby reducing the probability of the battery cell 16 accidentally falling. When the lifting cantilever 8 leaves the bottom of the battery cell 16, the bottom of the battery cell 16 is suspended in the air, and the vertical drive mechanism 10 can lower the battery cell 16 in the vertical direction to achieve the entry of the battery cell 16 into the shell. The vertical drive mechanism 10 can drive the adsorption mechanism to rise and fall in the vertical direction, and then can drive the battery cell 16 to descend when the battery cell enters the shell, thereby constraining the descending trajectory and descending speed of the battery cell 16, avoiding the battery cell 16 from free fall and damage or position displacement, improving the accuracy and stability of the battery cell 16 when entering the shell, ensuring the yield and efficiency of shell entry, and improving the product yield.
