In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0042] The invention provides a battery core gluing device, which is used for sticking adhesive tapes on the upper and lower surfaces of a battery core tab.

[0043] like Figure 1 The cell gluing device includes a positioning module 100, a tape transfer module 200 and a tape pressing module 300. The positioning module 100 and the tape pressing module 300 are opposite to each other along a first horizontal direction (X-axis direction), and the tape transfer module 200 is arranged between the positioning module 100 and the tape pressing module 300.

[0044] The positioning module 100 is used to fix the battery body of the battery cell, and the tabs of the battery cell extend from the front end of the positioning module 100 .

[0045] like Figure 2 The positioning module 100 includes a positioning plate 101 arranged on the top thereof, and the positioning plate 101 is provided with a limiting groove 1011 for placing the battery cell body. The shape of the limiting groove 1011 corresponds to the shape of the battery cell body, that is, in this embodiment, the width of the limiting groove 1011 is the same as the width of the battery cell body, and the length of the limiting groove 1011 is the same as the length of the battery cell body. Of course, the length of the limiting groove 1011 can be less than the length of the battery cell body, so that the pole ear can be further extended from the limiting groove 1011.

[0046] Furthermore, the limiting groove 1011 also exerts a downward adsorption force on the battery cell body, thereby further improving the limiting and fixing effect on the battery cell body.

[0047] The positioning module 100 further includes a suction cup 102, which is located below the positioning plate 101, and the suction end of the suction cup 102 is connected to the limiting groove 1011, and the suction cup 102 provides vacuum negative pressure. That is, the suction cup 102 provides vacuum negative pressure and then the battery body is sucked by the suction cup 102.

[0048] like Figure 3-4 The tape transfer module 200 includes a material taking component and a transfer component. The material taking component and the transfer component are separately arranged. The material taking component is used to carry the tape, and the transfer component is used to transfer the material taking component to the bottom of the pole ear.

[0049] The material taking component includes a support table 201 and a suction table 202. The top of the support table 201 is used to support the tape, and the suction table 202 is connected to the support table 201 and enables the support table 201 to absorb the tape.

[0050] The support platform 201 is provided with three support columns 2011 capable of absorbing the adhesive tape, and the positions of the three support columns 2011 correspond one by one to the two ends and the middle position of the adhesive tape.

[0051] In this embodiment, the three support columns 2011 are all provided with adsorption pipes extending downward from their upper surfaces, and the adsorption end of the suction table 202 is connected to the adsorption pipes, thereby adsorbing the tape while supporting it to prevent the tape from collapsing and deforming during the transfer process.

[0052] The transfer assembly includes a first cylinder 203 and a connecting rod 204 . The output end of the first cylinder 203 moves in a vertical direction and is detachably connected to the suction table 202 . The connecting rod 204 can slide in a second horizontal direction. The top end of the connecting rod 204 is fixedly connected to the first cylinder 203 .

[0053] The connecting rod 204 is arranged along the second horizontal direction ( Figure 1 The support table 201 can be set to take the tape from the tape output device and then transfer the tape to the pole ear position. The second cylinder 303 can control the suction table 202 to move in the vertical direction, that is, the tape can be attached to the lower surface of the pole ear when moving upward. After the first cylinder 203 is separated from the suction table 202, the connecting rod 204 drives the first cylinder 203 to transfer and connects to another material taking component.

[0054] It should be noted that in this embodiment, the length of the middle support column 2011 among the three support columns 2011 corresponds to the length of the pole ear, that is, when the support column 2011 moves upward, the tape portion on its surface can be attached to the bottom of the pole ear, forming two non-support areas between the three support columns 2011.

[0055] like Figures 5 to 7 As shown, the adhesive tape pressing module 300 includes a rolling body 301 and a pressing rod 302. The rolling body 301 has two non-supporting areas respectively corresponding to the two non-supporting areas, and the pressing rod 302 is arranged between the two rolling bodies 301. The pressing rod 302 and the rolling body 301 can move along the first horizontal direction, that is, move in the direction facing the positioning module 100 and abut against the material picking assembly, that is, before the transfer assembly leaves, the pressing rod 302 presses and fixes the material picking assembly, and the rolling body 301 can also move along the vertical direction and the second horizontal direction.

[0056] First, the two rolling bodies 301 move along the first horizontal direction and extend to the bottom of the two non-support areas. Then, the rolling bodies 301 move upward and drive the tape to fold. The rolling bodies 301 move to the upper surface of the pole ear. The two rolling bodies 301 roll along the upper surface of the pole ear one after another, and finally complete two rollings to stick the tape on the top of the pole ear.

[0057] Combination Figures 5 to 7In order to realize the above-mentioned stroke of the rolling body 301 and the clamping rod 302, the pressing belt module 300 also includes a second cylinder 303, a third cylinder 304 and a fourth cylinder 305. The second cylinder 303 drives the clamping rod 302 to move along the first horizontal direction. The third cylinder 304 is provided with two, and the two third cylinders 304 are arranged on both sides of the second cylinder 303. The third cylinder 304 drives the fourth cylinder 305 to move in the vertical direction, and the fourth cylinder 305 drives the rolling body 301 to move along the second horizontal direction.

[0058] In this embodiment, the two third cylinders 304 are staggered in the vertical direction to make way for other components.

[0059] Further, the adhesive tape module further includes a connecting frame 306, a connecting plate 307 and a fifth cylinder 308. The fifth cylinder 308 drives the connecting frame 306 to move along the first horizontal direction. The top of the connecting frame 306 is connected to the second cylinder 303. The front end of the connecting frame 306 is provided with a connecting plate 307. Both ends of the connecting plate 307 are respectively provided with a third cylinder 304. The fifth cylinder 308 can push the connecting frame 306, the connecting plate 307, the second cylinder 303, the third cylinder 304, the fourth cylinder 305, the rolling body 301 and the pressing rod 302 to move as a whole.

[0060] like Figure 8 In another embodiment, the positioning module 100, the adhesive tape module 300 and the material taking component each have two groups, and the positioning module 100, the adhesive tape module 300 and the material taking component of each group correspond to each other, and the two groups of positioning modules 100 and adhesive tape modules 300 are arranged along the second horizontal direction, and only one transfer component is provided. That is, one transfer component drives the corresponding material taking component to move to the corresponding positioning module 100, and when the transfer component descends from a certain material taking component, the positioning module 100 is glued, and at this time the transfer component can continue to transfer to another material taking component, thereby improving the glue application efficiency.
