Description

Technical Field

[0001] This invention relates to the field of battery processing technology, and in particular to an adhesive applicator and a winding device. Background Technology

[0002] In the production of lithium-ion batteries, cell winding is a crucial step, typically performed using a winding machine. During winding, the machine usually holds cathode electrode rolls, anode electrode rolls, and separator rolls, which are then unwound and wound together to form the battery cell. To ensure a continuous supply of electrodes and separators for ongoing winding, when an electrode or separator roll is used up, a new roll needs to be installed. Double-sided adhesive or similar bonding agents are used to attach the end of the old roll to the beginning of the new roll.

[0003] Currently, the common practice is to manually apply double-sided tape to the head of the new roll and then press the tail of the old roll against the double-sided tape on the head of the new roll to connect the new and old rolls. However, manual tape application is not only time-consuming and labor-intensive, but also requires stopping the winding machine, which reduces winding efficiency and is not conducive to the rapid completion of the winding operation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an adhesive application device that solves the problems of time-consuming and labor-intensive manual adhesive application, which also easily reduces winding efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An adhesive applicator is used to adhere double-sided adhesive rolls to a material roll, the double-sided adhesive rolls comprising release paper and a plurality of double-sided adhesive bodies spaced apart along the length of the release paper, the plurality of double-sided adhesive bodies being disposed on a first side of the release paper. The adhesive applicator includes:

[0007] Connector;

[0008] A sliding seat, which is slidably connected to the connecting seat;

[0009] A feeding roller is rotatably connected to the sliding seat, and the feeding roller is provided with a feeding part for releasing the double-sided film roll;

[0010] A take-up roller is rotatably connected to the connecting seat, and the take-up roller is provided with a take-up part for winding the release paper;

[0011] A plurality of guide rollers are provided on the connecting seat and the sliding seat for drawing the release paper from the feeding section to the receiving section;

[0012] An adhesive roller is rotatably connected to the sliding seat and abuts against the second side of the release paper.

[0013] Optionally, the adhesive applicator further includes a fixing mechanism, which is mounted on the connecting seat and / or the sliding seat and is configured corresponding to the release paper to fix the release paper.

[0014] Optionally, the fixing mechanism includes a first fixing member and a second fixing member; the first fixing member is disposed on the sliding seat to form a first fixing position for fixing the release paper on the sliding seat; the second fixing member is disposed on the connecting seat to form a second fixing position for fixing the release paper on the connecting seat.

[0015] Optionally, the first fixing member is provided with a first telescopic part and a first fixing part fixed on the first telescopic part, and the first fixing part forms a first fixing position with a through rod on the sliding seat; the second fixing member is provided with a second telescopic part and a second fixing part fixed on the second telescopic part, and the second fixing part forms a second fixing position with a through rod on the connecting seat.

[0016] Optionally, both the first fixing part and the second fixing part are provided with elastic buffers on the side near the guide rod.

[0017] Optionally, the adhesive applicator further includes a first drive mechanism, which is disposed on the connecting seat and drivenly connected to the sliding seat to slide and adjust the sliding seat.

[0018] Optionally, the adhesive applicator further includes a second drive mechanism, which is disposed on the connecting seat and drivenly connected to the take-up roller to rotate and adjust the take-up roller.

[0019] Optionally, the adhesive applicator further includes a third drive mechanism for driving connection with the connector to move the connector closer to or further away from the roll.

[0020] Optionally, the adhesive applicator further includes a torque generator, which is mounted on the sliding seat, and the feeding roller is connected to the torque generator via a rotating shaft.

[0021] The present invention also provides a winding device, including the adhesive applicator described above.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] This invention provides an adhesive applicator. In use, a double-sided adhesive roll is placed on the feeding section, and the release paper extends along several rollers to the receiving section of the receiving roller after exiting the feeding section. Before applying the adhesive, the sliding seat is slidably adjusted to the initial adhesive application position at the first end of the connecting seat, so that the front end of the double-sided adhesive body on the release paper is exactly placed at the front adhesive application position of the roll. Then, the adhesive application roller presses the double-sided adhesive body against the roll. While the sliding seat is slidably adjusted along the second end of the connecting seat, the feeding section releases the double-sided adhesive roll, and the adhesive application roller continues to press the double-sided adhesive body against the roll until the sliding seat is slidably adjusted to the adhesive application completion position at the second end of the connecting seat. This allows a piece of double-sided adhesive body to be tightly attached to the roll, so that the tail of the old roll can be connected to the head of the new roll. In summary, this adhesive applicator can automatically attach the double-sided adhesive to the head of a new roll of material, saving time and effort, and eliminating the need to stop the winding machine, thus improving winding efficiency.

Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0034] The term "comprising" and its variations used in this invention are open-ended, meaning "including but not limited to". The term "based on" means "at least partially based on". The technical solutions of this invention will be further described below with reference to the accompanying drawings and specific embodiments; it should be understood that, for ease of description, only the parts related to this invention are shown in the drawings, not the entire structure.

[0035] Please refer to the attached reference. Figure 1 To be continued Figure 6 This invention provides an adhesive applicator for attaching a double-sided adhesive roll 1 to a material roll 10. The double-sided adhesive roll 1 includes a release paper 11 and a plurality of double-sided adhesive bodies 12 spaced apart along the length of the release paper 11. The plurality of double-sided adhesive bodies 12 are disposed on a first side of the release paper 11. The adhesive applicator includes:

[0036] Connector 2;

[0037] Sliding seat 3 is slidably connected to connecting seat 2;

[0038] Feeding roller 4 is rotatably connected to sliding seat 3 and is provided with feeding part for releasing double-sided film roll 1;

[0039] The take-up roller 5 is rotatably connected to the connecting seat 2, and the take-up roller 5 is provided with a take-up part for taking up the release paper 11.

[0040] Several guide rollers 6 are provided on the connecting seat 2 and the sliding seat 3 to pull the release paper 11 from the feeding section to the receiving section.

[0041] The adhesive roller 7 is rotatably connected to the sliding seat 3, and the adhesive roller 7 abuts against the second side of the release paper 11.

[0042] According to the above scheme, when in use, the double-sided adhesive roll 1 is placed on the feeding section, and the release paper 11 extends along several rollers 6 to the receiving section of the receiving roller 5 after coming out of the feeding section. Before applying the adhesive, the sliding seat 3 is slidably adjusted to the initial adhesive application position at the first end of the connecting seat 2, so that the front end of the double-sided adhesive body 12 on the release paper 11 is just placed at the front adhesive application position of the roll 10. Then, the adhesive application roller 7 presses the double-sided adhesive body 12 against the roll 10. Then, while the sliding seat 3 is slidably adjusted along the second end of the connecting seat 2, the feeding section releases the double-sided adhesive roll 1, and the adhesive application roller 7 continues to press the double-sided adhesive body 12 against the roll 10 until the sliding seat 3 is slidably adjusted to the adhesive application completion position at the second end of the connecting seat 2. This allows a double-sided adhesive body 12 to be tightly attached to the roll 10, so that the tail of the old roll can be connected to the head of the new roll 10. In summary, this adhesive applicator can automatically attach the double-sided adhesive body 12 to the head of a new roll 10, saving time and effort, and eliminating the need to stop the winding machine, thus improving winding efficiency.

[0043] Furthermore, in order to ensure that the release paper 11 and the double-sided adhesive body 12 between the feeding section and the adhesive roller 7 are always in a taut state, thereby helping to ensure the adhesion quality of the double-sided adhesive body 12 and preventing the two ends of the double-sided adhesive body 12 from sticking together, the adhesive applicator also includes a fixing mechanism 8. The fixing mechanism 8 is installed on the connecting seat 2 and / or the sliding seat 3 and is set corresponding to the release paper 11 for fixing the release paper 11.

[0044] Specifically, in order to achieve a better fixing effect, the fixing mechanism 8 includes a first fixing member 81 and a second fixing member 82; the first fixing member 81 is disposed on the sliding seat 3 to form a first fixing position for fixing the release paper 11 on the sliding seat 3; the second fixing member 82 is disposed on the connecting seat 2 to form a second fixing position for fixing the release paper 11 on the connecting seat 2.

[0045] In this embodiment, during the adhesive preparation process of sliding the sliding seat 3 from the adhesive application completion position to the adhesive application initial position, the first fixing member 81 fixes the release paper 11 at the first fixing position, so that the release paper 11 and the double-sided adhesive body 12 can always be kept taut during the sliding of the sliding seat 3. Moreover, the second fixing member 82 releases the release paper 11 to facilitate the take-up part to roll up the release paper 11 between the first fixing member 81 and the take-up part. During the adhesive application process of sliding the sliding seat 3 from the adhesive application initial position to the adhesive application completion position, the first fixing member 81 releases the release paper 11, and the second fixing member 82 fixes the release paper 11 at the second fixing position, so that the release paper 11 and the double-sided adhesive body 12 can always be kept taut when unwinding the adhesive. At the same time, by fixing the release paper 11 at the second fixing position by the second fixing member 82 instead of by the take-up roller 5, the fixation of the release paper 11 can be more reliable and the risk of breakage of the release paper 11 can be reduced, so as to facilitate the effective performance of the adhesive application operation.

[0046] Furthermore, in order to more conveniently fix or release the release paper 11 to meet the usage requirements, the first fixing member 81 is provided with a first telescopic part and a first fixing part fixed on the first telescopic part, and the first fixing part and the through roller 6 on the sliding seat 3 form a first fixing position; the second fixing member 82 is provided with a second telescopic part and a second fixing part fixed on the second telescopic part, and the second fixing part and the through roller 6 on the connecting seat 2 form a second fixing position.

[0047] In this embodiment, when the first telescopic part drives the first fixing part closer to the roller 6 or the second telescopic part drives the second fixing part closer to the roller 6, the release paper 11 can be fixed; conversely, by driving the first fixing part or the second fixing part in a certain direction, the release paper 11 can be released. During the application of adhesive, only one of the first fixing part or the second fixing part is needed to fix the release paper 11.

[0048] Furthermore, in order to avoid damaging the release paper 11 by clamping and thus reduce the risk of the release paper 11 breaking, elastic buffers are provided on the side of the first fixing part and the second fixing part near the roller 6.

[0049] In this embodiment, the elastic buffer can be made of soft rubber or sponge.

[0050] Furthermore, to facilitate automatic driving adjustment of the sliding seat 3, allowing it to slide between the initial adhesive application position and the completed adhesive application position to meet adhesive application needs, the adhesive application device also includes a first driving mechanism 9. The first driving mechanism 9 is mounted on the connecting seat 2 and is drivenly connected to the sliding seat 3 to slide and adjust the sliding seat 3. In this embodiment, the first driving mechanism 9 can be a lead screw motor or an electric telescopic component.

[0051] Furthermore, to facilitate automatic rotation adjustment of the take-up roller 5 for winding the release paper 11, the adhesive applicator also includes a second drive mechanism 13. The second drive mechanism 13 is mounted on the connecting seat 2 and is drivenly connected to the take-up roller 5 to rotate and adjust the take-up roller 5. In this embodiment, the second drive mechanism 13 can be a rotary motor or a rotary cylinder.

[0052] Furthermore, to facilitate position adjustment of the connecting seat 2 so that the adhesive roller 7 on the connecting seat 2 is closer to or farther from the material roll 10 for convenient adhesive application or replacement of the material roll 10, the adhesive application device also includes a third drive mechanism 14. The third drive mechanism 14 is used to drive the connecting seat 2 to move the connecting seat 2 closer to or farther from the material roll 10. In this embodiment, the third drive mechanism 14 can be a lead screw motor or an electric telescopic component.

[0053] Furthermore, in order to ensure that the release paper 11 and the double-sided adhesive body 12 are always in a preset tension state between the feeding section and the adhesive roller 7 to meet the adhesive application requirements, the adhesive application device also includes a torque generator, which is mounted on the sliding seat 3, and the feeding roller 4 is connected to the torque generator via a rotating shaft.

[0054] This invention also provides a winding device, including a winding machine body and the aforementioned adhesive applicator. Since both the adhesive applicator and the material roll are installed outside the winding machine body, it is not necessary to open the winding machine's safety door during roll changing and adhesive applicator operations. This improves roll changing safety and avoids disrupting the negative pressure environment inside the winding machine, thus saving energy and increasing winding efficiency, thereby facilitating efficient and safe winding operations.

[0055] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
