Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a highly efficient and damage-free battery core shelling device. Background Art

[0002] With the rapid development of electronic technology and new energy industries, the battery industry is also developing continuously. Among them, lithium-ion cylindrical batteries are a type of battery commonly used in daily life and automotive electronics. In the traditional battery cell shelling process, it is necessary to push the incoming battery cell into the battery cell shell. After searching, the Chinese invention patent application with patent application number CN202111049564.0 discloses a battery cell shelling mechanism, which drives the shelling push rod to push the battery cell through the intermittent transmission module, so that the battery cell rises into the steel shell to ensure the shelling accuracy of the insulating diaphragm between the battery cell and the bottom of the steel shell. The shelling push rod can drive the steel shell to move up. After the steel shell and the shrapnel are staggered, the shrapnel pops up and blocks the opening of the steel shell. The shrapnel provides support to ensure that the battery cell will not fall from the steel shell after entering the shell, so as to achieve rapid shelling. However, although this battery cell shelling mechanism can achieve rapid shelling, it is easy for the battery cell to not correspond to the center of the shell during the shelling process, resulting in scratches on the surface of the battery cell, and the yield rate is low.

[0024] like Figure 1-6 As shown, the high-efficiency and damage-free battery cell shelling device includes a frame 1, on which a feeding mechanism 2, a battery cell lifting mechanism 3, a battery cell initial shelling mechanism 4, a battery cell middle shelling mechanism 5, a battery cell final shelling mechanism 6 and a battery cell shell pushing mechanism 7 are provided. The battery cell initial shelling mechanism 5 and the feeding mechanism 2 are respectively located on the left and right sides of the battery cell lifting mechanism 3, the battery cell middle shelling mechanism 5 is located between the battery cell initial shelling mechanism 4 and the battery cell final shelling mechanism 6, and the battery cell shell pushing mechanism 7 is located on the side of the battery cell final shelling mechanism 6. It can be understood that during operation, the battery cell is fed to the top of the battery cell lifting mechanism 3 through the feeding mechanism 2, and the battery cell lifting mechanism 3 lifts the battery cell to the battery cell initial shelling mechanism 4, and then the battery cell initial shelling mechanism 4, the battery cell middle shelling mechanism 5 and the battery cell end rotating shelling mechanism 6 successively implement the battery cell initial shelling, battery cell middle shelling and battery cell end shelling operations, and finally the battery cell shell pushing mechanism 7 pushes the completed battery shell to the next station.

[0025] Specifically, the feeding mechanism 2 includes a feeding track 11, a feeding drive motor 12, a feeding turntable 13 and a feeding turntable motor 14, the feeding drive motor 12 and the feeding turntable motor 14 are respectively connected to the feeding track 11 and the feeding turntable 13, and a cell transition zone 15 is provided between the feeding track 11 and the feeding turntable 13. It can be understood that the feeding drive motor 12 and the feeding turntable motor 14 can be general electric motors, etc., for driving the feeding track 11 and the feeding turntable 13 to operate respectively, so as to sequentially transport the cells to the cell lifting mechanism 3.

[0026] Specifically, a plurality of battery cell shelling telescopic jigs 16 are installed on the feeding turntable 13, and the battery cell shelling telescopic jigs 16 are sequentially distributed along the edge of the feeding turntable 13. It can be understood that the battery cell shelling telescopic jigs 16 are used to support the battery cell, and each battery cell shelling telescopic jig 16 corresponds to the battery cell lifting mechanism 3. When the battery cell lifting mechanism 3 is working, the battery cell is lifted from the bottom of the battery cell shelling telescopic jig 16, so as to be clamped by the battery cell initial shelling mechanism 4.

[0027] Specifically, the battery cell lifting mechanism 3 includes a battery cell lifting cylinder 17, a push rod bracket 18, and a push rod 19 mounted on the push rod bracket 18. The push rod 19 is transmission-connected to the battery cell lifting cylinder 17, and the push rod 19 is located below the battery cell shell-entering telescopic fixture 16. It can be understood that the battery cell lifting cylinder 17 can be a general cylinder, etc., for driving the push rod 19 to move upward.

[0028] Specifically, the battery cell initial shelling mechanism 4 includes a base 20, on which are provided an initial shell pressing assembly 21, an initial shelling turntable motor 22 and an initial shelling turntable 23 transmission-connected to the initial shelling turntable motor 22, on which are provided a plurality of general lifting assemblies 24, on which are provided a shell clamping assembly 25 and a battery cell lifting assembly 26 in sequence, on which are provided an initial shelling battery cell clamping assembly 27 aligned with the shell clamping assembly 25, and on which is provided the battery cell lifting assembly 26.

It can be understood that when working, a shell is placed on the inner side of the shell clamping assembly 25, the initial shell feed turntable motor 22 drives the initial shell feed turntable 23 to rotate to the battery cell feeding station, and the total lifting assembly 24 drives the initial shell feed battery cell clamping assembly 27 to the battery cell. At this time, the battery cell clamping assembly clamps the battery cell, and the total lifting assembly 24 drives the initial shell feed battery cell clamping assembly 27 to rise, so that the battery cell leaves the battery cell feeding station. At this time, the initial shell feed turntable motor 22 drives the initial shell feed The turntable 23 rotates, so that the total lifting assembly 24 comes under the initial shell pressing assembly 21. While the initial shell pressing assembly 21 presses the shell downward, the battery cell lifting assembly 26 drives the initial shell entering battery cell clamping assembly 27 to move upward, so that the upper section of the battery cell enters the inner side of the shell, and the initial shell entering battery cell clamping assembly 27 releases the battery cell, which is clamped by the shell clamping assembly 25. The battery cell is sent to the next station under the action of the initial shell entering turntable motor 22 driving the turntable, completing the initial shell entry of the battery cell.

[0029] Specifically, the battery core middle-section shelling mechanism 5 includes a middle-section shelling frame 28, on which a middle-section shelling turntable 29, a middle-section shelling turntable motor 210, a middle-section shell pressing assembly 211 and a middle-section shell pushing assembly 212 are arranged.

It can be understood that by adding a middle section shell pressing assembly 211 to push the shell so that it can cover the battery cell, the middle section shell entry turntable motor 210 drives the middle section shell entry turntable 29 to transfer the battery cell to the middle section shell pushing assembly 212, the first magnetic suction assembly 215 and the second magnetic suction assembly 216 are used to absorb the shell to fix the shell, and finally the middle section shell pushing assembly 212 pushes the shell with the battery cell to the next workstation to complete the middle section shell entry of the battery cell.

[0030] Specifically, the battery cell terminal end rotating shell entry mechanism 6 includes a terminal shell entry frame 31, on which a terminal shell entry shaft 32 and a terminal shell entry drive motor 33 are provided, which is transmission-connected to the terminal shell entry shaft 32.

The first battery cell shell bracket 35, the second battery cell shell bracket 36, the third battery cell shell bracket 37 and the fourth battery cell shell bracket 38 are distributed in sequence at the vertices of a square. It can be understood that the final shell entry drive motor 33 can be an electric motor, etc., which is used to drive the final shell entry shaft 32 to rotate, thereby driving the rotating frame 34 to rotate, and then driving the battery cell shell bracket to make a circular motion; the first battery cell shell bracket 35 receives the battery cell shell with the battery cell delivered from the previous workstation (at this time, the opening of the battery cell shell faces downward, and the battery cell has not completely entered the battery cell shell). When the first battery cell shell bracket 35 rotates to the original position of the third battery cell shell bracket 37, the battery cell completely enters the battery cell shell under the action of its own gravity. At this time, the opening of the battery cell shell faces upward, and the final shell entry of the battery cell is completed.

[0031] Specifically, the battery cell shell ejection mechanism 7 includes a shell ejection cylinder 40, a shell ejection rod 41 and a discharge track 42. The shell ejection rod 41 is in transmission connection with the shell ejection cylinder 40, and the battery cell shell bracket is located between the discharge track 42 and the shell ejection rod 41. It can be understood that the shell ejection cylinder 40 can be a general cylinder, etc., which is used to drive the shell ejection rod 41 to push the battery cell shell forward onto the discharge track 42, thereby completing the operation of inserting the battery cell into the shell.

[0032] It can be understood that the utility model has a reasonable design and a unique structure. It adopts a three-stage shelling method. First, the battery cell is fed to the top of the battery cell lifting mechanism 3 through the feeding mechanism 2, and the battery cell lifting mechanism 3 lifts the battery cell to the battery cell initial shelling mechanism 4, and then the battery cell initial shelling mechanism 4, the battery cell middle shelling mechanism 5 and the battery cell end rotating shelling mechanism 6 successively realize the battery cell initial shelling, battery cell middle shelling and battery cell end shelling, and finally the battery cell shell pushing mechanism 7 pushes the completed battery shell to the next station, which can avoid scratches on the surface of the battery cell, improve the yield rate, thereby improving the battery production efficiency, and the production efficiency is relatively high.
