[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. EMBODIMENT

[0030] Please refer to Figures 1-7The utility model provides a novel cylindrical battery tab positioning device, which comprises a tab alignment mechanism and a feeding mechanism 20. The tab alignment mechanism comprises a first alignment assembly 11, a second alignment assembly 12, an extension drive assembly and a detection piece 13. The first alignment assembly 11 comprises two passive wheels 111 arranged side by side. The second alignment assembly 12 comprises a driving wheel 121 and a rotary drive 122. The rotary drive 122 is a motor controlled by a PLC pulse controller. The rotary part of the rotary drive 122 is connected to the driving wheel 121. The rotary drive 122 drives the driving wheel 121 to rotate. The driving wheel 121 is located on one side of the two passive wheels 111. The center of the driving wheel 121 is located on the center line of the two passive wheels 111. The driving wheel 121 and the two passive wheels 111 are arranged in an isosceles triangle shape. The area between the driving wheel 121 and the two passive wheels 111 is the alignment operation area.

[0031] The extension drive assembly is used to drive the first alignment assembly 11 and the second alignment assembly 12 to move closer or farther away at the same time and to move back and forth between the working position and the standby position. When the first alignment assembly 11 and the second alignment assembly 12 are in the working position, they are close to each other. At this time, the driving wheel 121 and the two passive wheels 111 are close to each other. The three can clamp the battery cup 50 in the alignment operation area. At this time, the rotary drive 122 drives the driving wheel 121 to rotate, which can drive the battery cup 50 to rotate, thereby adjusting the position of the tab on the battery cup 50. When the first alignment assembly 11 and the second alignment assembly 12 are in the standby position, they are far away from each other. At this time, the driving wheel 121 and the two passive wheels 111 are far away from each other. The battery cup 50 can pass through the alignment operation area.

[0032] The first alignment assembly 11 and the second alignment assembly 12 are arranged on both sides of the feeding mechanism 20. The feeding surface of the feeding mechanism 20 is provided with a cup carrier 21. The cup carrier 21 is used to place the battery cup 50. After the battery cup 50 is placed on the cup carrier 21, it can be detachably connected with the cup carrier 21 and can rotate relative to the cup carrier 21. The battery cup 50 is provided with a battery placement position.

[0033] After the cell carrier cup 50 containing the cell is mounted on the carrier cup carrier 21, the feeding mechanism 20 transports the cell carrier cup 50 through the alignment operation area, and the feeding mechanism 20 pauses the transportation when the cell carrier cup 50 reaches the alignment operation area. The telescopic driving assembly drives the first alignment assembly 11 and the second alignment assembly 12 to move from the standby position to the working position. The driving wheel 121 cooperates with the two driven wheels to clamp the cell carrier cup 50, and then the rotary driving member 122 drives the cell carrier cup 50 to rotate. The cell on the cell carrier cup 50 also rotates. The detection member 13 is a positioning sensor in the form of a photoelectric switch or a proximity switch, and is arranged in the alignment operation area. The detection member 13 is linked with the rotary driving member 122. During the rotation of the cell, the detection member 13 detects the position of the tab. When the detection member 13 detects that the tab is aligned, the rotary driving member 122 stops, and the telescopic driving assembly drives the first alignment assembly 11 and the second alignment assembly 12 to move from the working position to the standby position. The driving wheel 121 and the two driven wheels 111 are separated from the cell carrier cup 50, and then the feeding mechanism 20 carries the cell carrier cup 50 away from the alignment operation area.

[0034] In order to improve the accuracy of the rotation of the cell carrier cup 50, the outer ring of the driving wheel 121 and / or the driven wheel 111 is rubberized. After rubberizing, the friction between the driving wheel 121 and / or the driven wheel 111 and the cell carrier cup 50 is larger, which can avoid slipping.

[0035] The cylindrical cell tab positioning device of the embodiment is used to mount the cell on the cell carrier cup 50 and then on the cell carrier of the feeding mechanism 20. When the feeding mechanism 20 sends the cell to the tab alignment mechanism for tab alignment, the driving wheel 121 and the driven wheel 111 of the tab alignment mechanism act on the cell carrier cup 50, drive the cell carrier cup 50 to rotate, drive the cell to rotate, realize the rapid alignment of the cell tab, and effectively avoid the direct contact between the tab alignment mechanism and the cell, which causes damage to the surface of the cell.

[0036] The cell carrier cup 50 is a cylinder with an open top. The inner cavity of the cell carrier cup 50 is a cell placement position. When the cell is placed in the inner cavity of the cell carrier cup 50, the tab on the top of the cell is exposed outside the cell carrier cup 50. The top of the carrier cup carrier 21 is provided with a cup accommodating groove, and the side of the carrier cup carrier 21 is provided with three avoiding holes for the driving wheel 121 and the two driven wheels 111 to extend into. When the first alignment assembly 11 and the second alignment assembly 12 are in the working position, the driving wheel 121 and the two driven wheels 111 extend into the carrier cup carrier 21 through the three avoiding holes and abut against the outer wall of the cell carrier cup 50. Of course, in some embodiments, the slot of the cup accommodating groove is lower than the wheel body of the driving wheel 121 and the driven wheel 111. At this time, the carrier cup carrier 21 can also not be provided with avoiding holes, and the driving wheel 121 and the two driven wheels 111 can be matched with the cell carrier cup 50 above the cup accommodating groove.

[0037] Please refer toFigure 1 and Figure 3 The feeding mechanism 20 is a frequency transmission belt conveyor, and a plurality of cup carriers 21 are uniformly arranged on the feeding surface of the feeding mechanism 20 along the conveying direction. The conveying distance of the feeding mechanism 20 is consistent with the distribution interval of the cup carriers 21. When one cup carrier 21 is sent out of the alignment operation area, the adjacent cup carrier 21 is sent into the alignment operation area.

Each driving wheel 121 corresponds to a rotary driving member 122, and each driving wheel 121 corresponds to two driven wheels 111. The area between each driving wheel 121 and the corresponding two driven wheels 111 is an alignment operation area. Each alignment operation area is provided with a detection member 13, which is linked and matched with the corresponding rotary driving member 122 of the alignment operation area. When multiple alignment operation areas are arranged, the conveying distance of the feeding mechanism 20 should also be adjusted appropriately. For example, when four driving wheels 121 are arranged, the conveying distance of the feeding mechanism 20 is the interval of four cup carriers 21. Through such design, the alignment operation of the tabs of four battery cells can be performed at the same time, effectively improving the processing efficiency.

The second telescopic driving member 15 and the second alignment assembly 12 are arranged on the second platform. The telescopic part of the second telescopic driving member 15 is connected with the second alignment assembly 12 and drives the driving wheels 121 of the second alignment assembly 12 to move back and forth between the second working position and the second standby position.
