Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of the present application. Embodiments

[0026] Please refer to Figure 1 Figure 5 The adhesive tape feeding module of the battery automatic adhesive tape applying equipment in the embodiment comprises a support vertical plate 1, a feeding roll assembly 2, a waste roll assembly 3, a pressing cylinder 4 and a fixed-length pulling assembly 5. The feeding roll assembly 2, the waste roll assembly 3 and the fixed-length pulling assembly 5 are all installed on the support vertical plate 1. The feeding roll assembly 2 is used for installing a roll of material, and the waste roll assembly 3 is used for winding waste material. The support vertical plate 1 is further provided with a cutting table 6 and a plurality of adhesive tape guide wheels 7 on the side thereof. The cutting table 6 is provided with one adhesive tape guide wheel 7 on each side thereof. The pressing cylinder 4 is fixedly installed on the side of the support vertical plate 1 close to the cutting table 6. The pressing cylinder 4 is fixedly connected with a pressing block 8 at the extension end thereof. The pressing block 8 is located directly above the cutting table 6. The pressing cylinder 4 drives the pressing block 8 to move up and down. When pressed, the pressing block 8 can fix one end of the adhesive tape close to the feeding roll assembly 2.

[0027] The adhesive tape discharged from the roll of material on the feeding roll assembly 2 reaches the cutting table 6 after passing through the plurality of adhesive tape guide wheels 7. The two adhesive tape guide wheels 7 on the two sides of the cutting table 6 make the adhesive tape adhere to the cutting surface of the cutting table 6. The other end of the adhesive tape reaches the waste roll assembly 3 after passing through the plurality of adhesive tape guide wheels 7. The waste roll assembly 3 comprises a winding wheel, a driving motor and two synchronous wheels. The two synchronous wheels are connected with the driving motor and the winding wheel respectively. The driving motor drives the winding wheel to rotate through the synchronous wheels. The support vertical plate 1 is further provided with a winding buffer guide wheel and a proximity switch on the side thereof. The winding buffer guide wheel slides in the up-down direction on the side of the support vertical plate through a slide rail. The proximity switch is located at the lower position of the slide rail and is used for detecting whether the winding buffer guide wheel is located at the lower end of the slide rail. When the winding buffer guide wheel slides to the lower end of the slide rail, the proximity switch is triggered. The proximity switch transmits an electrical signal to a controller. The controller controls the driving motor of the waste roll assembly 3 to rotate, so as to achieve the winding effect.

[0028] ​The fixed-length material pulling assembly 5 includes a clamping jaw 501, a three-axis air cylinder 502, a first sliding block 503, a first travel switch 504, and a second travel switch 505, and is used for clamping and pulling the waste material, wherein the three-axis air cylinder 502 is fixedly installed on the back of the support upright plate 1, the first sliding block 503 is in sliding connection with the three-axis air cylinder 502, the extension end of the three-axis air cylinder 502 is fixedly connected with one end of the first sliding block 503 and drives the first sliding block 503 to move, the extension and retraction action of the three-axis air cylinder 502 is transmitted to the clamping jaw 501 through the first sliding block 503, the clamping jaw 501 pulls the adhesive tape, the clamping jaw 501 is fixedly connected with the first sliding block 503 through a clamping air cylinder, the clamping air cylinder controls the opening and closing of the clamping jaw 501, so as to realize the clamping and releasing of the adhesive tape, the first travel switch 504 and the second travel switch 505 are fixedly installed with the three-axis air cylinder 502, the first sliding block 503 is fixedly installed with a stop block 9, the stop block 9 is located between the first travel switch 504 and the second travel switch 505, when the first sliding block 503 drives the stop block 9 to move to touch the first travel switch 504 or the second travel switch 505, the travel switch sends a signal to control the three-axis air cylinder 502 to stop action, so as to accurately control the material pulling length and ensure that the feeding length is consistent each time.

[0029] The feeding roll assembly 2 includes a unwinding wheel 201, a spring 202, a spring pressing ring 203, a fixed flange 204, a material rod 205, an extrusion pressing ring 206, and an extrusion nut 207, wherein the fixed flange 204 is fixedly installed with the support upright plate 1, the inner side of the fixed flange 204 is provided with a bearing, the material rod 205 is rotatably connected with the fixed flange 204 through the bearing, the unwinding wheel 201 is fixedly connected with one end of the material rod 205, the unwinding wheel 201 is used for installing the adhesive tape roll, the material rod 205 is rotatable, the spring 202 is fixedly connected with one spring pressing ring 203 at both ends, the spring 202 and the spring pressing ring 203 are sleeved outside the material rod 205, the fixed flange 204 is fixedly connected with an extrusion pressing ring 206 on the side close to the spring pressing ring 203, the extrusion nut 207 is threadedly and rotatably connected with the end of the material rod 205 away from the unwinding wheel 201, there is an extrusion pressing ring 206 between the extrusion nut 207 and the spring pressing ring 203, the outer side surface of the material rod 205 is provided with a limiting guide strip 11, the material rod 205 drives the extrusion pressing ring 206 to rotate through the limiting guide strip 11.

[0030] The compression nut 207 is threaded onto one end of the feed rod. After installation, the compression nut 207 compresses the compression ring 206, and the pressure from the spring 202 makes the compression ring 206 and the spring ring 203 fit tightly together. The contact surfaces of the compression ring 206 and the spring ring 203 are provided with anti-slip textures to increase the friction between them. The limiting guide strip 11 makes the compression ring 206 rotate with the feed rod 205. When the unwinding wheel 201 rotates, it drives the feed rod 205 to rotate. The feed rod 205 drives one compression ring 206 to rotate through the limiting guide strip 11. The torque is transmitted through the friction between the compression ring 206 and the spring ring 203. The reaction force generated by the torsion of the spring 202 can automatically adjust the tension to prevent the tape from loosening or being overstretched.

[0031] A winding buffer assembly 12 is also installed on the side of the support plate 1. The winding buffer assembly 12 includes a first cylinder 1201 and a buffer wheel 1202. The buffer wheel 1202 slides on the side of the support plate 1 via a buffer slider 13 and a guide rail 14. The first cylinder 1201 is fixedly installed on the side of the support plate 1. The buffer slider 13 is fixedly connected to the telescopic end of the first cylinder 1201. When the first cylinder 1201 extends or retracts, it drives the buffer slider 13 to slide along the guide rail 14, thereby causing the buffer wheel 1202 to move.

[0032] When the tape is cut on the cutting table 6, the pressure block 8 and the gripper 501 fix the two ends of the tape. At this time, the first cylinder 1201 extends to pull the tape out from the unwinding wheel 201. After the cutting is completed, the pressure cylinder 4 drives the pressure block 8 to move upward, and the fixed length pulling component 5 drives the gripper 501 to pull the tape. At the same time, the first cylinder 1201 retracts and drives the buffer wheel 1202 to move upward. The buffer wheel 1202 releases the pulled tape.

[0033] The extension of cylinder 1201 causes the buffer wheel 1202 to move downward. The buffer wheel 1202 can store adhesive tape. When cylinder 1201 retracts, it releases the stored adhesive tape. During the fixed-length pulling of the tape, cylinder 1201 and the three-axis cylinder 502 retract synchronously. The tape pulled by the fixed-length pulling component is the tape stored in the buffer wheel 1202. This avoids the direct pulling of the tape of the feeding roll component 2 during the fixed-length pulling of the tape, which would be affected by its tension fluctuations, and further ensures the stability of the material supply.

[0034] Through the automatic tension adjustment of the feeding roll assembly 2, the pre-storage and release of the unwinding buffer assembly 12, the precise length control of the fixed-length pulling assembly 5, and the auxiliary fixing and guiding of the pressing cylinder 4 and the adhesive tape guide wheel 7, the fixed-length stable feeding of adhesive tape is achieved.

As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
