[0002] Lithium batteries are becoming more and more widely used. The capacity and safety of battery cells have always been the focus of people's attention. The integrity of the battery cell current collector has a certain correlation with the battery cell capacity and heat generation. The rupture of the current collector will affect the charging and discharging of the corresponding part of the pole piece, and will lose some capacity; the rupture of the current collector will reduce the current collector flow area. The reduction of the flow area will increase the heat generation of the current collector, thus affecting the safety performance. After ultrasonic welding of the lithium battery pole ear of the double-winding butterfly welding, insulating tape needs to be applied to prevent the pole ear from invading the winding core and causing the risk of short circuit. At present, there is a lack of a gluing device for gluing the pole ear. Utility Model Content

[0028] Example 1

[0029] See also Figures 1 to 3 As shown, this embodiment provides a gluing device for a square aluminum shell battery cell, which includes: a pressing plate 10, one side of which is provided with an inclined surface, and the upper surface of the pressing plate 10 is provided with a non-stick coating;

[0030] The glue sticking mechanism includes a glue sticking head 2 and a connecting member 3. The glue sticking head 2 is provided with a cavity inside and a plurality of vacuum suction holes 201 communicating with the cavity are provided at the bottom. The glue sticking head 2 is connected to an air pipe. The connecting member 3 connects the glue sticking head 2 and an external driving device to drive the glue sticking head 2 to move up and down.

[0031] The pressure plate 10 presses the winding core to prevent one end of the adhesive paper from sticking to the diaphragm inside the winding core during the subsequent pressing process of the adhesive paper. One side of the adhesive paper is aligned with one side of the gluing head 2. The external driving device drives the connecting part 3 to move downward and then drives the gluing head 2 to move downward. The adhesive paper first hits the non-adhesive pressure plate 10, and the gluing head continues to move downward. The left side of the adhesive paper will contact the left side of the pole ear during the downward process and then stick to the left side of the pole ear until the gluing head 2 presses the pole ear and sticks the right side of the adhesive paper to the right side of the pole ear to complete the gluing. When the pressure plate 10 is released, the winding core will rebound upward. Since the adhesive paper is completely attached to the pole ear in an L shape, the problem of the adhesive paper pulling the pole ear will not occur; the external air pipe draws air to make the vacuum suction hole 201 at the bottom of the gluing head 2 suck the adhesive paper. When the adhesive paper contacts the pole ear, the external air pipe supplies air; the external driving device is a cylinder.

[0032] According to the gluing device for square aluminum shell battery cells of the utility model embodiment, the core is pressed by the pressing plate 10 to prevent one end of the adhesive paper from sticking to the diaphragm inside the core during the subsequent pressing process. The vacuum suction hole 201 at the bottom of the gluing head 2 sucks the adhesive paper, and the external driving device drives the connecting part 3 to move downward and then drives the gluing head 2 to move downward quickly to achieve gluing on the pole ear. The adhesive paper is completely attached to the pole ear in an L shape, and the problem of the adhesive paper pulling the pole ear will not occur.

[0033] It should be noted that the bottom of the adhesive tape head 2 is a smooth surface so that the adhesive tape can be kept horizontal.

[0034] It should be noted that the connecting member 3 is L-shaped and is provided with a plurality of through holes 301 . The external driving device is connected to the connecting member 3 through bolts and the through holes 301 .

[0035] It should be noted that a buffer device is also included between the glue sticking head 2 and the connecting member 3, which plays a role in protecting the tab after the glue sticking head 2 moves downward to press the adhesive tape onto the tab.

[0036] It should be noted that the buffer device includes two guide rods 4 and two springs 5. One end of the guide rod 4 is connected to the glue head 2, and the other end is slidably connected to the connecting piece 3. The spring 5 is sleeved on the guide rod 4 and between the glue head 2 and the connecting piece 3. When the glue head 2 is pressed onto the pole ear, the connecting piece 3 continues to move downward, one end of the guide rod 4 moves upward relative to the connecting piece 3, and the connecting piece 3 squeezes the spring 5, thereby playing a buffering role.
