[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0025] Reference Figures 1 to 4 The present invention discloses a double-sided tape applying device. Specifically, the device includes a tape unwinding and cutting assembly 10 and a tape applying and rewinding assembly 20. The tape unwinding and cutting assembly 10 is disposed on one side of the tape applying and rewinding assembly 20. After the double-sided tape roll is unwound by the tape unwinding and cutting assembly 10, it is rewound by the tape applying and rewinding assembly 20. The tape unwinding and cutting assembly 10 is used to apply the double-sided tape to the electrode, and the tape applying and rewinding assembly 20 is used to rewind the release paper roll after the double-sided tape is applied.

[0026] The unwinding and cutting assembly 10 includes an unwinding drive module 101 and a cutting module 102. The cutting module 102 is arranged on one side of the unwinding drive module 101. The unwinding drive module 101 is used to drive the double-sided adhesive film to rotate so that the unwinding speed of the double-sided adhesive film matches the winding speed of the release paper, which can ensure the stability of the tension, and the cutting module 102 can cut the double-sided adhesive film.

[0027] The unwinding drive module 101 includes an unwinding seat 1011 and an unwinding motor 1012. The rubber cutting module 102 includes a rubber cutting cylinder 1021, a micrometer 1022, a rubber cutting blade 1023, a rubber cutting table 1024 and a rubber cutting roller 1025. The driving end of the unwinding motor 1012 is connected to the unwinding seat 1011. A double-sided tape roll is placed on the unwinding seat 1011. Driven by the unwinding motor 1012, the unwinding seat 1011 can be rotated, thereby causing the double-sided tape roll on the unwinding seat 1011 to rotate as a whole. Two rubber cutting rollers 1025 are provided on one side of the unwinding seat 1011. The two rubber cutting rollers 1025 are arranged along the movement direction of the double-sided tape film. A rubber cutting table 1024 is provided between the two rubber cutting rollers 1025. When the double-sided tape film moves toward the rubber cutting module 102, it will first contact the first rubber cutting roller 1025 in the rubber cutting module 102, then contact the rubber cutting table 1024, and finally contact the second rubber cutting roller 1025 in the rubber cutting module 102.

[0028] The rubber cutting cylinder 1021 is connected to the rubber cutting blade 1023, which is driven by the rubber cutting cylinder 1021 to cut the double-sided tape roll. The rubber cutting blade 1023 is arranged opposite to the rubber cutting table 1024, with a gap between the rubber cutting blade 1023 and the rubber cutting table 1024 for the double-sided tape roll to pass through. In this embodiment, the rubber cutting table 1024 is block-shaped, but other shapes are also possible, as long as the surface of the rubber cutting table 1024 facing the rubber cutting blade 1023 contacts the double-sided tape roll when the double-sided tape roll passes through the gap between the rubber cutting blade 1023 and the rubber cutting table 1024. When the double-sided tape roll contacts the cutting surface 1024, the cutting cylinder 1021 drives the cutting blade 1023 toward the double-sided tape roll on the cutting surface 1024. The cutting blade 1023 and the cutting surface 1024 cooperate to cut the double-sided tape. A micrometer 1022 controls the length of the cutting cylinder 1021. During commissioning, the micrometer 1022 can be used to precisely adjust the extension of the cutting cylinder 1021, ensuring that the cutting blade 1023 accurately cuts the double-sided tape without cutting the release paper.

[0029] The tape sticking and winding component 20 includes a tape sticking module 201 and a winding driving module 202. The winding driving module 202 is arranged on one side of the tape sticking module 201. The double-sided adhesive tape roll passes through the tape cutting module 102 and then passes through the tape sticking module 201 and is finally wound by the winding driving module 202. The tape sticking module 201 includes a tape sticking roller 2011, a tape sticking roller 2012, a tape sticking cylinder 2013 and a fixing block 2014. The double-sided adhesive tape roll passing through the unwinding and cutting component 10 then passes through the tape sticking roller 2011 and the tape sticking roller 2012 and is finally wound by the winding driving module 202. The winding driving module 202 includes a winding motor 2021 and a winding seat 2022. The driving end of the winding motor 2021 is connected to the winding seat 2022. Under the drive of the winding motor 2021, the winding seat 2022 can wind the release paper with double-sided adhesive already stuck.

[0030] There are two tape sticking rollers 2011. A tape sticking roller 2012 is arranged between the two tape sticking rollers 2011. The output end of the tape sticking cylinder 2013 is connected to a fixing block 2014. The fixing block 2014 has an opening, and the tape sticking roller 2012 is rotatably connected at the opening. In this embodiment, the shape of the fixing block 2014 is "匚"-shaped. The opening of the "匚" is used for rotatably connecting the tape sticking roller 2012, and the other end of the "匚" opposite to the opening is connected to the output end of the tape sticking cylinder 2013. In some embodiments, the shape of the fixing block 2014 can also be "C", "<" and other shapes, as long as it is ensured that the tape sticking roller 2012 can be rotatably connected at the opening of the fixing block 2014 and the other end of the fixing block 2014 opposite to the opening can be connected to the output end of the tape sticking cylinder 2013. An isolation plate 2015 is arranged at the contact position between the tape sticking roller 2012 and the pole piece. The isolation plate 2015 is installed at both ends of the fixing block 2014. The isolation plate 2015 does not affect the rotation of the tape sticking roller 2012. The width of the isolation plate 2015 is slightly larger than the width of the double-sided adhesive tape, which can prevent the pole piece from sticking to the double-sided adhesive and thus avoid damaging the pole piece.

[0031] When the double-sided adhesive tape roll passes through the first tape sticking roller 2011, then passes through the tape sticking roller 2012, and finally passes through the other tape sticking roller 2011, it is wound by the winding seat 2022. Since the output end of the tape sticking cylinder 2013 is connected to the tape sticking roller 2012, the tape sticking cylinder 2013 can drive the tape sticking roller 2012 to move towards the pole piece. At this time, the side with double-sided adhesive on the double-sided adhesive tape roll faces the pole piece. Under the driving effect of the tape sticking cylinder 2013, the tape sticking roller 2012 moves towards the pole piece and sticks the double-sided adhesive on the pole piece.

[0032] In this embodiment, the driving units in the tape cutting module 102 and the tape sticking module 201 are driven by cylinders. In some embodiments, the driving units can also be driven by other commonly used methods such as screw rods by those skilled in the art.

[0033] Reference Figure 5 At the beginning of double-sided tape application, the glue cylinder 2013 extends out to press the glue head onto the pole piece, and then a transverse movement module is set at the bottom of the double-sided tape application device. Driven by the transverse movement module, the double-sided tape application device can complete horizontal movement. Since the double-sided tape is stuck to the pole piece on one side, it will slowly separate from the release paper. At this time, the unwinding motor 1012 and the winding motor 2021 are set to torque mode. By sensing the torque change through the unwinding motor 1012 and the winding motor 2021, zero-tension glue application can be achieved on the pole piece. When the glue application is about to end, the glue cutting cylinder 2013 extends out to control the glue cutting blade 1023 to cut the double-sided tape in advance. At this time, the transverse movement module continues to move. The cut double-sided tape will continue to stick to the pole piece under the tension of the winding motor 2021 and the pole piece on the release paper. Finally, the double-sided tape fracture sticks to the edge of the pole piece and the glue application stops.

[0034] The above is a specific description of the preferred implementation of the present invention, but the invention of the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
