[0017] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0018] Example 1

[0019] See also Figure 1-2 : A glue sticking device for ultrasonic process, including two groups of glue suction components 1, elastic buffer components 2 and adhesive tape 3, the tops of the two groups of glue suction components 1 are adsorbed with adhesive tape 3, and the bottoms are respectively connected with elastic buffer components 2, both sides of the adhesive tape 3 are provided with sticky parts, and the middle is a non-sticky part, the non-sticky part faces the pole ear 4, and the sticky parts on both sides face the welding mark 5 and the winding core 6 respectively.

[0020] The adhesive tape of this embodiment adopts an interval gluing structure, and the middle part in contact with the pole ear is non-sticky, which can effectively prevent the pole ear from tearing; the glue suction component mainly functions for the tape adsorption, and provides a placement platform for the tape through the internal cavity and negative pressure; the elastic buffer component mainly functions to softly stick the adhesive tape according to the surface contour of the core to prevent damage to the core, and the gluing state is more consistent.

[0021] It should be noted that the elastic buffer component of this embodiment is composed of two independent parts. The cylinder pushes the feed amount upward to a certain extent, and the compression amount of the buffer component spring is determined according to the distance difference between the adapter plate, the large surface of the winding core and the adhesive tape, thereby simultaneously realizing the adhesion of the adhesive tape to the welding mark of the adapter plate pole ear and the large surface of the winding core.

[0022] In a specific example, it also includes an isolation plate 7 and a cylinder 8, wherein the telescopic end of the cylinder 8 is connected to the isolation plate 7, and the top of the isolation plate 7 is connected to the elastic buffer component 2.

[0023] It should be noted that after the glue suction component absorbs the adhesive tape, the cylinder can work to push the whole body upward. When the glue suction component contacts the weld mark between the adapter and the pole ear with the adhesive tape, the spring in the elastic buffer component is compressed, and the adhesive tape is respectively attached to the weld mark between the adapter and the pole ear and above the large surface of the winding core.

[0024] The cylinder, isolation plate, elastic buffer component and glue suction component of this embodiment are all connected to each other by screws; when the cylinder pushes the whole upward, the glue suction component contacts the adapter plate and the large surface of the winding core with the adhesive tape, the spring in the elastic buffer component is compressed, and the welding mark of the glue suction component, the adapter plate and the pole ear and the large surface of the winding core are pressed tightly so that the adhesive tape can be smoothly attached. The space above the isolation plate mainly serves to provide a buffer area for the compression of the spring.

[0025] The cylinder lifts and drives the device upward while compressing the spring. When the tape approaches the adapter and the large surface of the battery cell, the sticky area of ​​the tape is attached to it, the negative pressure channel is closed, and the tape sticking is completed.

[0026] In a specific example, the adhesive tape 3 is zebra adhesive tape.

[0027] In a specific example, the weld mark 5 is the connection area between the tab 4 and the adapter 9 .

[0028] In a specific example, negative pressure channels are provided inside the two groups of glue suction components 1 .

[0029] The adhesive suction component of this embodiment realizes the adsorption of the adhesive tape through the negative pressure channel, and provides a placement platform for the adhesive tape through the internal cavity and negative pressure, thereby realizing stable adhesive application.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
