[0040] Specifically, Figure 1 and Figure 2As shown, when attaching the adhesive tape 2 to the battery cell 3, the attaching device 1 described in the embodiment of the present application first adsorbs the adhesive tape 2 through the first vacuum adsorption part 111 of the adsorption structure 11, and then moves the adsorption structure 11 to the upper side of the battery cell 3, and then drives the roller-attaching part 121 of the roller-attaching structure 12 to roll the adhesive tape 2 adsorbed by the first vacuum adsorption part 111 to the battery cell 3, thereby achieving the attachment of the adhesive tape 2 to the battery cell 3.

[0041] Among them, since the embodiment of the present application first adsorbs the adhesive tape 2 through the adsorption structure 11 when attaching the adhesive tape 2, the adsorption structure 11 can provide a self-balancing function for the adhesive tape 2, that is, make the adhesive tape 2 more flat, so that when the adhesive tape 2 is rolled with the roller-sticking part 121, it is possible to more effectively avoid the adhesive tape 2 from generating wrinkles when attached, thereby significantly improving the battery yield and the appearance performance of the battery. In addition, compared with the prior art of attaching the adhesive tape 2 with a stamp-type attachment structure, the embodiment of the present application rolls the adhesive tape 2 with the roller-sticking part 121, which can better eliminate the bubbles generated when the adhesive tape 2 is attached to the battery cell 3, thereby further improving the battery yield and the appearance performance of the battery.

[0042] In addition, the roller-attaching portion 121 described in the embodiment of the present application further includes a motor and a rubber roller, and the motor can drive the rubber roller to rotate so as to roll the adhesive paper 2 adsorbed by the first vacuum adsorption portion 111 onto the battery cell 3 .

[0046] Specifically, Figure 3As shown, the roller-sticking structure 12 described in the embodiment of the present application includes a roller-sticking portion 121, a mounting seat 122 and a cylinder 125. The roller-sticking portion 121 is installed on the mounting seat 122. The cylinder 125 is provided on the side of the mounting seat 122 away from the roller-sticking portion 121. The cylinder 125 can drive the roller-sticking portion 121 and the mounting seat 122 to move up and down, thereby effectively realizing the dual functions of the roller-sticking portion 121 of avoiding air and sticking.

The elastic member 123 can adjust the rolling force applied by the roller-sticking portion 121 to the adhesive tape 2 when the roller-sticking portion 121 is rolling the adhesive tape 2, thereby effectively realizing the adaptive adjustment function of the roller-sticking portion 121 and significantly broadening the application scope of the attaching device 1.

[0048] Among them, the elastic member 123 can be a spring, a pressing plate, an elastic retaining ring, etc., and the spring can be a coil spring, a gas spring, a rubber spring, etc. Technical personnel in this field can choose according to actual needs, and this application does not make any specific restrictions here.

[0050] The guide portion 124 may be a sliding guide sleeve structure, so that the guide portion 124 can provide precise sliding guidance for the elastic member 123 , thereby further improving the stability and reliability of the adaptive adjustment function of the roller contact portion 121 .

[0051] Of course, the guide portion 124 may also be other guide structures such as a guide rod, and those skilled in the art may make a selection according to actual needs, and this application does not make any specific limitation here.

[0052] In addition, the roller-sticking structure 12 described in the embodiment of the present application can be fixed to one side of the adsorption structure 11, and the roller-sticking part 121 of the roller-sticking structure 12 and the first vacuum adsorption part 111 of the adsorption structure 11 are located in the same plane; or, the roller-sticking structure 12 can be slidably arranged on one side of the adsorption structure 11, so that the roller-sticking structure 12 can move up and down along the adsorption structure 11.

[0054] Specifically, the embodiment of the present application adds vacuum technology to the roller-sticking portion 121, that is, by setting adsorption holes on the rubber roller of the roller-sticking portion 121, so that the adsorption holes can adsorb the adhesive tape 2 onto the rubber roller, and then the rubber roller brings the adhesive tape 2 to the battery cell 3, and finally the rubber roller rolls the adhesive tape 2 onto the battery cell 3, thereby achieving the attachment of the adhesive tape 2 to the battery cell 3.

[0055] Among them, since the adhesive tape 2 is adsorbed by the adhesive roller when being attached, the motor of the roller-attaching portion 121 can be rotated to drive the adhesive roller to rotate and attach the adhesive tape 2, thereby more effectively avoiding wrinkles on the adhesive tape 2 when attached, and further eliminating bubbles generated when the adhesive tape 2 is attached to the battery cell 3, thereby significantly improving the battery yield and the appearance performance of the battery.

[0058] Among them, the first adsorption end 1111 includes a plurality of first adsorption holes 11111, and the plurality of first adsorption holes 11111 are connected to the first channel 1112, so that when the first adsorption end 1111 adsorbs the adhesive tape 2, the stability and reliability of the first adsorption end 1111 adsorbing the adhesive tape 2 can be further enhanced, and the flatness of the adhesive tape 2 adsorbed by the first adsorption end 1111 can be further improved.

[0060] Specifically, Figure 1 and Figure 2As shown, the attaching device 1 described in the embodiment of the present application can extract air through the second channel 1122 so that the second adsorption end 1121 can control the tension of the adhesive paper 2 adsorbed by the first adsorption end 1111, so that when the roller-attaching portion 121 rolls the adhesive paper 2, the flatness of the adhesive paper 2 can be effectively guaranteed, and wrinkles of the adhesive paper 2 during attachment can be further avoided, and bubbles generated when the adhesive paper 2 is attached to the battery cell 3 can be further eliminated, thereby significantly improving the battery yield and the appearance performance of the battery.
