[0026] The following will describe a two-drive multi-position cylindrical battery cell feeding device provided by the present invention in conjunction with Figures 1 to 5 as shown in the figure.

[0027] As Figure 1 shown, the two-drive multi-position cylindrical battery cell feeding device shown in this embodiment includes: a transfer mechanism 1, a battery cell flipping mechanism 2, and a battery cell pitch-changing mechanism 3.

[0028] The transfer mechanism 1 is used to transfer a plurality of battery cells 5 in a horizontal state on the battery cell conveying line 4 to the battery cell flipping mechanism 2. The battery cell flipping mechanism 2 is used to flip the plurality of battery cells 5 in the horizontal state to the vertical state. The transfer mechanism 1 is used to transfer the plurality of battery cells 5 in the vertical state to the battery cell pitch-changing mechanism 3. The battery cell pitch-changing mechanism 3 is used to adjust the pitch between any two adjacent battery cells 5 among the plurality of battery cells 5. The transfer mechanism 1 is used to transfer the plurality of battery cells 5 with the adjusted pitch on the battery cell pitch-changing mechanism 3 to the turntable fixture 6.

[0029] Specifically, for the two-drive multi-position cylindrical battery cell feeding device shown in this embodiment, through the adjustment of the battery cell attitude by the battery cell flipping mechanism 2 and the adjustment of the pitch between two adjacent battery cells 5 by the battery cell pitch-changing mechanism 3, that is, under the transfer action of the transfer mechanism 1, the battery cells 5 are adjusted by a step-by-step multi-position feeding method to meet the requirements of the flattening device in the next process. The turntable fixture 6 rotates the adjusted battery cells 5 to the flattening device for flattening treatment, ensuring the feeding efficiency of the battery cells 5 between the battery cell conveying line 4 and the turntable fixture 6.

[0030] In some embodiments, as Figure 2As shown in the figure, the transfer mechanism shown in this embodiment includes a first jaw 11, a second jaw 12, and a third jaw 13; the first jaw 11 is movably arranged between the battery cell step feeding line 4 and the battery cell flipping mechanism 2, that is, the first jaw 11 transfers the battery cell 5 on the battery cell step feeding line 4 to the battery cell flipping mechanism 2 for flipping processing; the second jaw 12 is movably arranged between the battery cell flipping mechanism 2 and the battery cell pitch-changing mechanism 3, that is, the second jaw 12 transfers the battery cell 5 on the battery cell flipping mechanism 2 to the battery cell pitch-changing mechanism 3 for pitch-changing processing; the third jaw 13 is movably arranged between the battery cell pitch-changing mechanism 3 and the turntable fixture 6, that is, the third jaw 13 transfers the battery cell 5 on the battery cell pitch-changing mechanism 3 to the turntable fixture 6, thus completing the entire loading process.

[0031] In some embodiments, as Figure 2 shown, the transfer mechanism 1 shown in this embodiment further includes a first driving member 14 and a second driving member 15; the first driving member 14 is connected to the first jaw 11, and the second driving member 15 is respectively connected to the second jaw 12 and the third jaw 13, and the second driving member 15 is used to drive the second jaw 12 and the third jaw 13 to move synchronously.

[0032] Specifically, two driving members are used to drive the three jaws. Among them, the second jaw 12 and the third jaw 13 move synchronously, so that the battery cell 5 can be transferred simultaneously between the battery cell flipping mechanism 2 and the battery cell pitch-changing mechanism 3 and between the battery cell pitch-changing mechanism 3 and the turntable fixture 6, that is, the transfer of the battery cell 5 at two workstations can be achieved simultaneously by one action of the second driving member 15, and accordingly, the transfer efficiency of the battery cell 5 is improved.

[0033] Among them, the first driving member 14 and the second driving member 15 can be air cylinders, hydraulic cylinders or electric push rods.

[0034] In some embodiments, as Figure 3 shown, the battery cell flipping mechanism shown in this embodiment includes a flipping frame 21 and a flipping driving member 22; the flipping frame 21 is connected to the flipping driving member 22, and the transfer mechanism 1 is used to transfer the battery cell 5 in a horizontal state on the battery cell step feeding line 4 to the flipping frame 21.

[0035] Specifically, after the first jaw 11 transfers the battery cell 5 in a horizontal state to the flipping frame 21, the flipping driving member 22 drives the flipping frame 21 to rotate 90 degrees, so as to flip the battery cell 5 in a horizontal state to a vertical state.

[0036] Among them, the flipping driving member 22 can be a motor.

[0037] In some embodiments, as Figure 3As shown in the figure, the battery cell flipping mechanism 2 shown in this embodiment further includes a pushing component 23; the flipping frame 21 has a loading position and a clamping position. The transfer mechanism 1 is used to transfer the battery cells 5 in a horizontal state on the battery cell step conveyor line 4 to the loading position. The pushing component 23 is used to push the battery cells 5 at the loading position to the clamping position, and the flipping driving part 22 is used to drive the flipping frame 21 to flip the multiple battery cells 5 at the clamping position to a vertical state.

[0038] Specifically, the pushing component 23 pushes the battery cells 5 from the loading position to the clamping position, thereby clamping the battery cells 5 to prevent the battery cells 5 from falling during the flipping process.

[0039] In some embodiments, as Figure 3 shown in the figure, a detection component 7 is provided on the flipping frame 21 shown in this embodiment. When the detection component 7 determines that there are battery cells 5 stored at the loading position, the pushing component 23 pushes the battery cells 5 at the loading position to the clamping position.

[0040] Among them, the detection component 7 can be a photoelectric sensor.

[0041] In some embodiments, as Figures 3 to 5 shown in the figure, a positioning block 8 is provided on the flipping frame 21 shown in this embodiment. The loading position and the clamping position are recessed in the positioning block 8. The positioning block 8 is provided with a first avoidance groove 81 and a second avoidance groove 82. The first avoidance groove 81 is arranged close to the loading position, and the second avoidance groove 82 is arranged close to the clamping position. The axis of the first avoidance groove 81 is perpendicular to the axis of the second avoidance groove 82; the first avoidance groove 81 and the second avoidance groove 82 are used to avoid the transfer mechanism 1.

[0042] Specifically, when the first clamping jaw 11 transfers the battery cell 5 to the loading position, the second avoidance groove 82 is used for the first clamping jaw 11 to extend into, so as to facilitate the first clamping jaw 11 to place the battery cell 5 into the loading position; after the pushing component 23 pushes the battery cell 5 to the clamping position, the first avoidance groove 81 is exposed. After the positioning block 8 drives the battery cell 5 to a vertical state, the first avoidance groove 81 is used for the second clamping jaw 12 to extend into, so as to facilitate the second clamping jaw 12 to take out the battery cell 5 at the clamping position.

[0043] In some embodiments, as Figure 5 shown in the figure, the axis of the battery cell 5 on the positioning block 8 shown in this embodiment coincides with the axis of the positioning block 8, so as to play a good role in radial positioning of the battery cell 5.

[0044] In some embodiments, as Figure 1As shown in the figure, the two-wheel multi-position cylindrical battery cell feeding device in this embodiment further includes a frame 9; the battery cell step feeding line 4, the battery cell flipping mechanism 2, the battery cell pitch changing mechanism 3, and the turntable fixture 6 are arranged in sequence along the length direction of the frame 9. Correspondingly, multiple battery cells 5 on the battery cell flipping mechanism 2 and multiple battery cells 5 on the battery cell pitch changing mechanism 3 are both arranged along the width direction of the frame 9, reducing the occupied space of the overall structure in the length direction of the frame 9.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments or equivalently replace some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
