[0046] 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.

[0047] The composite process of the tab and the pole piece is a process of tightly combining the tab and the pole piece. Good composite of the tab and the pole piece can ensure that the current inside the battery can be efficiently conducted. In the existing tab and pole piece composite equipment, the tab and the pole piece are connected by welding. However, this connection mode is not firm, and burrs are easily generated in the welding process, which can cause damage to the tab and the pole piece, thereby affecting the safety and reliability of the battery.

[0048] Therefore, the application provides an ear cutting and compounding machine to effectively improve the reliability of the connection between the ear and the tab.

[0049] Referring to Figures 1 to 7 The application discloses an ear cutting and compounding machine, which comprises a unwinding device, a cutting device 500, a pretreatment device 800, a gluing device 1000 and a conveying assembly.

[0050] Specifically, the unwinding device comprises a unwinding roller 110, which is used for winding an ear tape; the cutting device comprises a cutting mechanism, which is used for cutting the ear tape to obtain an ear 1; the pretreatment device 800 is used for pretreating the surface of the ear 1 to increase the surface roughness of the ear 1; the gluing device 1000 is arranged on one side of the pretreatment device 800; and the conveying assembly is used for conveying the ear tape or the ear 1.

[0051] In the ear cutting and compounding machine, the ear 1 is obtained by cutting the ear tape by the cutting device, and the surface roughness of the ear 1 can be increased by the pretreatment device 800 before the ear 1 is compounded with the tab, so that the bonding effect when the ear 1 is compounded with the tab is improved, and the connection reliability of the ear 1 and the tab is improved. Meanwhile, the ear 1 and the tab are connected by the gluing and compounding mode, so that burrs can be avoided, the situation that the burrs damage the tab is avoided, and the safety and reliability of the battery cell can be improved.

[0052] Referring to Figure 1 and Figure 2 The unwinding device comprises a unwinding roller 110 and a plurality of guide rollers, the unwinding roller 110 is used for winding the ear tape, and the plurality of guide rollers are arranged at intervals and are each provided with a groove matched with the ear tape. The unwinding roller 110 winds the ear tape, and the unwinding end of the ear tape is sequentially wound on the grooves of the plurality of guide rollers. The ear tape can be straightened when passing through the grooves, and the situation that the fitting precision is reduced due to the buckling or winding when the ear 1 is attached to the tab can be reduced. It should be understood that the width of the groove is matched with the width of the ear tape.

[0053] In the embodiment, referring to Figure 1 and Figure 2 The guide rollers comprise a first guide roller 121, a second guide roller 122 and a third guide roller 123, the first guide roller 121, the second guide roller 122 and the third guide roller 123 each have a groove matched with the ear tape, and the ear tape is sequentially wound in the grooves of the first guide roller 121, the second guide roller 122 and the third guide roller 123.

[0054] Referring to Figure 1 and Figure 2The pretreatment device 800 is configured to pretreat the surface of the tab 1 to increase the surface roughness of the tab 1. In this way, the situation that the tab 1 cannot be adhered to the pole piece after being coated with glue can be prevented.

[0055] The conveying assembly is configured to move the tab material strip or the tab 1. Specifically, the conveying assembly is configured to drive the tab material roll to move so that the tab material strip is moved between the unwinding device and the cutting device 500. Meanwhile, the conveying assembly is also configured to move the tab 1 cut by the cutting device 500 to the working position of the pretreatment device 800, the glue coating device 1000 and other devices to complete various processing and compounding of the tab 1.

[0056] The glue coating device 1000 is configured to coat the surface of the tab 1 so that the tab 1 can be adhered to the pole piece.

[0057] In some embodiments of the present application, the tab cutting and compounding machine further comprises a first burr treatment device 700. The first burr treatment device 700 is arranged on the side of the cutting device away from the unwinding device. The first burr treatment device 700 is configured to treat the burr of the tab 1.

[0058] Referring to Figure 1 , Figure 3 and Figure 4 , the first burr treatment device 700 is arranged on the side of the cutting device 500 away from the shaping device 200. The first burr treatment device 700 is configured to treat the burr of the tab 1 to prevent the burr from scratching the pole piece. In addition, the burr of the tab 1 changes the preset position of the tab 1 adhered to the pole piece. Therefore, by treating the burr of the tab 1, the connection reliability of the tab 1 and the pole piece can be improved.

[0059] In the embodiments of the present application, after the tab 1 is cut, the first burr treatment device 700 can be used to remove the burr of the tab 1 to prevent the burr from scratching the pole piece. Meanwhile, before the tab 1 is compounded with the pole piece, the pretreatment device 800 can be used to increase the surface roughness of the tab to improve the adhesion effect when the tab 1 is compounded with the pole piece.

[0060] In one embodiment of the present application, the first burr treatment device 700 comprises two air cylinders arranged in an up-down manner. The output ends of the two air cylinders can abut each other. When treating the burr, the tab 1 is moved to the space between the two air cylinders. The up-down air cylinders are driven to move to pat the upper and lower surfaces of the tab 1 respectively, so that the burr is flush with the upper and lower surfaces of the tab 1. In this way, the adhesion degree of the tab 1 and the pole piece can be improved, and the situation that the burr scratches the pole piece can be reduced.

[0061] In some embodiments of the present application, referring to Figure 2 and Figure 7The one side of the cutting mechanism is provided with a first roller 510 which is higher than the cutting surface of the cutting mechanism and is used to lift the cut tab 1. In this way, the sticking of the material after cutting or the embedding of the material belt into the cutting device 500 can be reduced.

[0062] In some embodiments of the present application, the cutting device comprises a guide clamp and a cutting mechanism. The guide clamp is arranged on the one side of the cutting mechanism and is used to guide the tab material belt to be cut to prevent deviation from the preset cutting position during cutting.

[0063] In some embodiments of the present application, the tab cutting compound machine comprises a shaping device 200 which is arranged on the one side of the unwinding device. The shaping device 200 is used to flatten the tab material belt so that the tab 1 obtained by cutting the tab material belt can be kept flat, thereby improving the connection reliability of the tab and the pole piece.

[0064] In some embodiments of the present application, please continue to refer to Figure 2 and Figure 6 The shaping device 200 comprises two rows of roller pressing assemblies which are arranged in an upper and lower interval and are interference fitted. Each row of roller pressing assemblies comprises a plurality of second rollers 211 which are arranged in an interval and are staggered with each other in the conveying direction of the tab material belt. In actual application, the tab material belt passes between the two rows of roller pressing assemblies, so that the tab material belt can be flattened by means of the roller pressing assemblies.

[0065] It is worth understanding that the abutting surface of the last row of roller pressing assemblies and the tab material belt is a, and the abutting surface of the other row of roller pressing assemblies and the roller pressing assembly is b. The interference fit of the upper and lower two rows of roller pressing assemblies means that the abutting surface a and the abutting surface b are interference fitted. In this way, the pressure of the roller pressing assembly on the tab material belt can be at a reasonable level, and it is ensured that the tab material belt can be flattened.

[0066] Further, each second roller 211 is connected with a spring, and the tightness of each second roller 211 can be adjusted up and down to prevent the pressure of the second roller 211 on the tab material belt from being too large to damage the tab material belt, and also to avoid that the force of the second roller 211 on the tab material belt is too small to flatten the tab material belt.

[0067] In some embodiments of the present application, please refer to Figure 1 and Figure 2 The pretreatment device 800 comprises an ultrasonic welding module or a laser welding module which is used to process the surface of the tab 1 to increase the surface roughness of the tab 1.

The guiding part corresponding to the moving space of the tab clamping part is provided in a hollow structure, so that the tab clamping part can clamp and move the tab material belt forward from above and below the first channel.

[0073] In actual application, the tab clamping part can be a pneumatic claw, which can be used to clamp the tab material belt, and then drive the pneumatic claw and the tab material belt to move forward as a whole under the driving of the conveying module.

[0074] In the above implementation, the first channel is a groove in the guiding part, and the first channel can guide the position of the tab material belt, thereby reducing the deviation of the tab material belt during cutting, improving the cutting accuracy, and helping to improve the composite accuracy of the tab 1 and the pole piece.
