When a single bare cell tab folding device is used, the operator is required to pick up the folded cell and then put down the cell that needs tab folding before folding the tabs of the next bare cell. When a multiple bare cell tab folding device is used for folding the tabs simultaneously, the operator is still required to pick up and then put down the device again before continuing to work, and the work efficiency is low.

[0034] See also Figures 1 to 7The embodiment of the present application provides a folding ear device for a bare cell, comprising a base 1, a rotating mechanism 2, a gravity sensing device 23, a first folding ear mechanism 4, and a second folding ear mechanism 5.

The first folding ear mechanism 4 and the second folding ear mechanism 5 are both located above the disc 21; the first folding ear mechanism 4 includes a cylinder pressure rod 43 and a cylinder push rod 53, and the cylinder pressure rod 43 and the cylinder push rod 53 are both electrically connected to the controller; a positioning plate 24 is provided on the side of the bare cell placement hole 22, and the cylinder pressure rod 43 is perpendicular to the positioning plate 24; the cylinder push rod 53 is parallel to the positioning plate 24, and the bottom surface of the cylinder push rod 53 and the top surface of the positioning plate 24 are located on the same straight line.
[0035] Working principle and effect: The utility model adopts a rotatable disc 21, which is provided with bare cell placement holes 22 distributed in a circular row. The operator puts the bare cell 7 into the bare cell placement hole 22. After the gravity sensing device 23 below the bare cell placement hole 22 senses that the bare cell 7 is put down, it transmits a signal to the controller. After receiving the signal, the controller controls the first folding ear mechanism 4 and the second folding ear mechanism 5 to complete the operation of the folding ear 71 once. Specifically, assuming that the initial hole position of the bare cell placement hole 22 is hole position No. 1, the first hole position in the clockwise direction of hole position No. 1 is hole position No. 2, and the second hole position is hole position No. 3, and so on. In the initial state, the first folding ear mechanism 4 is located on hole position No. 3, and the second folding ear mechanism 5 is located on hole position No. 2; when the bare cell 7 is put into hole position No. 1, the gravity sensing device 23 senses that the bare cell 7 is put down, that is, it controls the disc 21 to rotate clockwise once, so that hole position No. 1 turns to hole position No. 2. The disc 21 rotates clockwise once, and the holes rotate once. When the disc 21 rotates once, the folding ear mechanism above the holes also works once. That is, when the hole 1 turns to the position of the hole 2, the second folding ear mechanism 5 located above the side of the hole 2 starts to work, and the push plate 56 is extended along the top surface of the positioning plate 24 to complete the first bending of the bare battery cell 7 (such as Figures 4 to 6 As shown in the figure, the operator continues to put the bare battery cell 7 into the empty hole position turned to hole position 1, and feels the gravity and continues to rotate once, so that hole position 2 is turned to hole position 3, and the first folding ear mechanism 4 located above hole position 3 starts to work, extending the pressing plate 45 in a direction perpendicular to the top surface of the positioning plate 24, completing the second bending of the bare battery cell 7 (as shown in the figure). Figure 4 , Figure 5 as well as Figure 7 As shown), after two bends, the folding of the pole ears is completed. The bare battery cell 7 with the folded pole ears will rotate with the disk 21 and return to the initial position No. 1. The operator will take out the bare battery cell 7 that has returned to position No. 1 and put in a new bare battery cell 7 that needs to have its pole ears folded. The operation is repeated in this way. The operator can pick up the completed bare battery cell 7 and put in a new bare battery cell 7 at the same time without affecting the work of the bare battery cell 7 that is already undergoing the folding of the pole ears. The automated operation of folding the pole ears of the bare battery cell 7 is realized, which greatly improves the work efficiency.
[0036] In one embodiment, Figure 2 or Figure 3 The side of the positioning plate 24 close to the bare cell placement hole 22 is an arc-shaped structure, and fits with the edge of the bare cell placement hole 22. The edge of the circular hole is provided with a positioning plate 24, and the part where the positioning plate 24 fits with the edge of the hole is provided with an arc-shaped structure. When a portion of the bare cell 7 is exposed outside the hole, the tab 71 can fall on the positioning plate 24. The positioning plate 24 is heightened to provide support for the folded tab, and while positioning the tab 71, it can protect the bare cell 7. Since a portion of the bare cell 7 is exposed outside, the push plate 56 is prevented from pushing the bare cell 7 out of the hole during the pushing process.
[0037] In one embodiment, Figures 1 to 5 As shown, the first folding lug mechanism 4 includes a first mounting rod 41, one end of which is connected to the connecting rod 31, and the other end is provided with a first vertical rod 42, and a cylinder pressure rod 43 is connected to the first vertical rod 42. Since the disc 21 will rotate with the bare cell 7, a portion of the bare cell 7 will be exposed on the bare cell placement hole 22. In order to facilitate the rotation of the disc 21, the column 3 is set higher. Therefore, the first vertical rod 42 is installed above the positioning plate 24 through the first mounting rod 41, and then the installation position of the cylinder pressure rod 43 is lowered through the first vertical rod 42, so as to facilitate the downward pressing of the folding lug 71.
[0038] In one embodiment, Figure 7 As shown, the cylinder pressure rod 43 includes a cylinder telescopic rod 44, which is connected to the first vertical rod 42, and a pressing plate 45 is provided at the telescopic end of the cylinder telescopic rod 44, and a chamfered structure 6 is provided at the bottom of one side of the pressing plate 45. The pressing plate 45 is driven up and down by the cylinder telescopic rod 44 to realize the action of pressing down and folding the pole ear 71. Furthermore, a chamfered structure 6 is provided on the edge of one side of the pressing plate 45 that contacts the pole ear 71, so as to avoid the situation that the pole ear 71 is damaged due to the sharp contact surface during the pressing process.
[0039] In one embodiment, Figures 1 to 5As shown, the second folding lug mechanism 5 includes a second mounting rod 51, one end of which is connected to the connecting rod 31, and the other end is provided with a second vertical rod 52, and a cylinder push rod 53 is connected to the second vertical rod 52. Since the disc 21 will rotate with the bare cell 7, a portion of the bare cell 7 will be exposed on the bare cell placement hole 22. In order to facilitate the rotation of the disc 21, the column 3 is set higher. Therefore, the second vertical rod 52 is installed above the outer side of the disc 21 through the two mounting rods, and then the installation position of the cylinder push rod 53 is lowered through the second vertical rod 52, so as to facilitate the forward pushing of the folding lug 71.
[0040] In one embodiment, Figure 6 As shown, the cylinder push rod 53 includes a cylinder 54, which is connected to the second vertical rod 52, and a piston rod 55 is provided on the cylinder 54. The telescopic end of the piston rod 55 is provided with a push plate 56, and a chamfered structure 6 is provided on one side of the bottom surface of the push plate 56. The piston rod 55 drives the push plate 56 to push forward and backward to achieve the action of pushing the folded pole ear 71 forward. Furthermore, the edge of the push plate 56 that contacts the pole ear 71 is provided with a chamfered structure 6, which avoids the situation that the pole ear 71 is damaged due to the sharp contact surface during the side pushing process.
[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
