[0001] This application relates to the field of adhesive application technology, and more particularly to an adhesive application tooling. Background Technology

[0002] A separatorless battery is a type of battery that uses a solid electrolyte instead of a traditional separator, offering extremely high thermal stability and safety. Because the electrodes in a separatorless battery lack the protection of a separator, burrs can easily pierce the solid electrolyte layer, causing short circuits. Therefore, adhesive must be applied to the edges of the electrodes.

[0003] Currently, the glue application is done manually, which makes it difficult to guarantee consistency, and the slow application speed leads to low production efficiency. Utility Model Content

The coating roller is rotatably connected to the body, and its circumferential surface is at least partially contained in the receiving groove and in contact with the adhesive liquid, and partially protrudes from the opening of the receiving groove and is close to the first surface or the second surface. When the coating roller rotates relative to the body, it can apply the adhesive liquid to the first surface and / or the second surface of the electrode sheet.

[0010] In one possible design, the body also has at least two openings communicating with the receiving tank, the bottom of the receiving tank having an adhesive groove extending along the bottom of the groove, the adhesive groove penetrating the body through the openings; the adhesive circulation mechanism is connected to the two openings respectively to supply adhesive to the adhesive groove from one opening and allow it to flow into the receiving tank, and to recover the remaining adhesive from the other opening.

[0011] In one possible design, the adhesive application mechanism further includes a doctor blade roller with its axis parallel to the axis of the adhesive application roller. The circumferential surface of the doctor blade roller has at least one blade extending along the axis, with the blade tip facing the circumferential surface of the adhesive application roller to scrape off a portion of the adhesive on the adhesive application roller.

[0012] In one possible design, the doctor blade roller is rotatably connected to the body and rotates in the opposite direction to the glue coating roller. At least a portion of the circumferential surface of the doctor blade roller is accommodated in the receiving groove, and the doctor blade roller and the glue coating roller are spaced apart along a direction perpendicular to the axis.

[0013] In one possible design, the adhesive application mechanism further includes:

[0014] The first driving unit includes a first driving member that drives the coating roller and a second driving member that drives the scraper roller, which can respectively drive the coating roller or the scraper roller to rotate relative to the body.

[0015] A first moving part, wherein the first driving part is adjustablely connected to the first driving member and / or the second driving member, the first moving part being capable of moving the first driving member and the second driving member closer or further apart to adjust the distance between the doctor blade roller and the coating roller; and / or,

[0016] The second moving part is adjustablely connected to the first driving part. The second moving part can drive the first driving part to move along the axial direction of the coating roller or the doctor blade roller to adapt to the width of the electrode sheet.

[0017] In one possible design, the adhesive application fixture further includes a fixing plate having a first fixing surface and a second fixing surface arranged opposite each other along a first direction. The adhesive application mechanism and the conveying mechanism are both mounted on the first fixing surface. A first support plate extending along the first direction is connected to the fixing plate. The adhesive application mechanism is movably connected to the first support plate. The first direction is perpendicular to the conveying direction of the electrode sheet and parallel to the axis of the supply roller or the recovery roller.

[0018] In one possible design, the first support plate has at least two spaced-apart first support plates in the second direction. The conveying mechanism includes a plurality of support rollers, which are disposed on both sides of the first support plate along the conveying direction of the electrode sheet. Two adhesive coating mechanisms on the two first support plates can respectively apply adhesive to the first surface and the second surface of the electrode sheet.

[0071] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0072] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0074] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0075] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0076] This application provides a gluing fixture, such as... Figure 1 As shown, the adhesive coating fixture includes an adhesive coating mechanism 2, a conveying mechanism 3, and an adhesive circulation mechanism 4. The conveying mechanism 3 includes a supply roller 31 and a recovery roller 32 arranged parallel to each other along the electrode conveying direction. The supply roller 31 is used to supply uncoated electrode sheets 5, and the recovery roller 32 is used to collect coated electrode sheets 5. The electrode sheet 5 includes a first surface and a second surface arranged opposite to each other. The adhesive coating mechanism 2 is located between the supply roller 31 and the recovery roller 32 along the electrode conveying direction, and is capable of applying adhesive to the first surface and / or the second surface of the electrode sheet 5 conveyed by the supply roller 31. The adhesive circulation mechanism 4 is connected to the adhesive coating mechanism 2 through a pipeline, and is used to supply adhesive to the adhesive coating mechanism 2 and recover any remaining adhesive in the adhesive coating mechanism 2. The electrode conveying direction is the direction from the supply roller 31 to the recovery roller 32.

[0077] In this embodiment, as Figure 1 As shown, the conveying mechanism 3 transports the electrode sheet 5 to the coating mechanism 2, where the coating mechanism applies adhesive to the first and / or second surfaces of the electrode sheet 5. Afterwards, the recovery roller 32 collects the coated electrode sheet 5. Therefore, the coating process can be entirely performed by the coating fixture without manual intervention, resulting in better coating consistency and faster coating speed, thereby improving production efficiency and reducing labor costs. The adhesive recycling mechanism 4 can recover and reuse the remaining adhesive in the coating mechanism 2, reducing adhesive waste.

[0078] like Figure 2As shown, the electrode 5 includes an active material region 51 and empty foil regions disposed on both sides of the active material region 51. By adjusting the coating mechanism 2, the adhesive can be applied to the interface between the active material region 51 and the empty foil region 52 to provide insulation and burr removal. The adhesive can be composed of polyimide (PI).

[0079] Optionally, the length of the adhesive extending from the empty foil area 52 to the active material area 51 after coating is between 5 and 10 mm.

[0080] Specifically, such as Figure 3 As shown, the coating mechanism 2 includes a body 21 and a coating roller 22. The body 21 has a receiving groove 211 for receiving adhesive liquid, and the opening of the receiving groove 211 faces the first surface or the second surface of the electrode 5. The coating roller 22 is rotatably connected to the body 21, and the circumferential surface of the coating roller 22 is at least partially received in the receiving groove 211 and in contact with the adhesive liquid, and partially protrudes from the opening of the receiving groove 211 and is close to the first surface or the second surface. When the coating roller 22 rotates relative to the body 21, it can apply adhesive liquid to the first surface and / or the second surface of the electrode 5.

[0081] The coating roller 22 has multiple protruding teeth on its circumferential surface. When the coating roller 22 rotates relative to the body 21, the multiple protruding teeth can carry the adhesive liquid and rotate it to contact the first surface and / or the second surface of the electrode 5, so as to apply the adhesive liquid to the first surface and / or the second surface of the electrode 5.

[0082] More specifically, such as Figure 4 As shown, the main body 21 also has at least two openings 213 that communicate with the receiving tank 211. The bottom of the receiving tank 211 is provided with a glue tank 212 extending along the bottom of the tank. The glue tank 212 passes through the main body 21 through the openings 213. The glue circulation mechanism 4 is connected to the two openings 213 respectively to supply glue to the glue tank 212 from one opening 213 and let it flow into the receiving tank 211, and to recover the remaining glue from the other opening 213.

[0083] Preferably, the receiving tank 211 is rectangular, and the glue tank 212 extends through the body 21 along its length, forming openings 213 at both ends of the body 21. The glue circulation mechanism 4 can supply glue to the coating mechanism 2 through the openings 213 and collect any remaining glue. Since the openings 213 at both ends of the body 21 have the same structure, the glue circulation mechanism 4 can supply glue to the coating mechanism 2 through either opening 213. This eliminates the need for the operator to spend time observing which opening 213 is the glue inlet and which is the glue outlet when assembling the coating mechanism 2, thus reducing the difficulty of assembling the coating mechanism 2.

[0084] Furthermore, such as Figure 5As shown, the glue coating mechanism 2 also includes a scraper roller 23, the axis of which is parallel to the axis of the glue coating roller 22. The circumferential surface of the scraper roller 23 has at least one scraper 231 extending along the axis, with the blade of the scraper 231 facing the circumferential surface of the glue coating roller 22 to scrape off part of the glue on the glue coating roller 22.

[0085] Before contacting the first or second surface of the electrode 5, the protruding teeth carrying the adhesive pass through the doctor blade roller 23. The blades of the doctor blade roller 23 can scrape off excess adhesive from the coating roller 22, ensuring that only a suitable amount of adhesive adheres to the coating roller 22. The axis of the doctor blade roller 23 is parallel to the axis of the coating roller 22, and the blades of the doctor blade 231 extend along the axial direction, resulting in a uniform thickness and high flatness of the adhesive applied to the first or second surface of the electrode 5, thus achieving high consistency in adhesive application.

[0086] Preferably, the thickness of the adhesive applied by the coating mechanism 2 to the first or second surface of the electrode 5 is between 5 μm and 20 μm. If the adhesive is too thick, it will cause poor contact between adjacent electrodes 5, resulting in excessive internal resistance of the produced battery. If the adhesive is too thin, it will be difficult for the adhesive to effectively insulate and wrap burrs.

[0087] Furthermore, the scraper roller 23 is rotatably connected to the body 21 and rotates in the opposite direction to the glue coating roller 22. At least part of the circumferential surface of the scraper roller 23 is accommodated in the receiving groove 211, and the scraper roller 23 and the glue coating roller 22 are spaced apart along the vertical axis.

[0088] When the scraper roller 23 rotates, it can scrape off some of the adhesive on the coating roller 22 more quickly and bring the scraped adhesive back into the receiving tank 211, preventing the adhesive from adhering to the scraper 231 and affecting the scraper 231 to continue to scrape off the adhesive, and reducing the waste of adhesive.

[0089] In one specific implementation, such as Figure 3 As shown, the coating mechanism 2 further includes: a first driving part, a first moving part 27, and a second moving part 13. The first driving part includes a first driving member 24 that drives the coating roller 22 and a second driving member 25 that drives the scraper roller 23, which can respectively drive the coating roller 22 or the scraper roller 23 to rotate relative to the body 21. The first moving part 27 is adjustablely connected to the first driving member 24 and / or the second driving member 25. The first moving part 27 can drive the first driving member 24 and the second driving member 25 to move closer to or further away from each other to adjust the distance between the scraper roller 23 and the coating roller 22. And / or, the second moving part 13 is adjustablely connected to the first driving part. The second moving part 13 can drive the first driving part to move along the axial direction of the coating roller 22 or the scraper roller 23 to adapt to the width of the electrode sheet 5.

[0090] The first driving component 24 can be a motor with an output shaft connected to the glue-applying roller 22. The motor drives the glue-applying roller 22 to rotate by rotating the output shaft.

[0091] like Figure 6 As shown, the second drive member 25 has a connecting shaft 251, which extends into the mounting hole 232 at the center of the scraper roller 23, thereby connecting the scraper roller 23 to the second drive member 25.

[0092] like Figure 7 As shown, the fixing block 26 is stepped to fit the first driving member 24 and the second driving member 25 respectively, so that the output shaft of the first driving member 24 can correspond to the height of the hole of the glue roller 22, and the connecting shaft 251 of the second driving member 25 can correspond to the height of the mounting hole of the scraper roller 23.

[0093] Optionally, the first moving part 27 has a slider, a slide rail and a micrometer. One of the slider and the slide rail is fixedly connected to the second driving member 25, and the other is fixedly connected to the fixed block 26. The distance between the scraper roller 23 and the glue coating roller 22 can be changed by adjusting the micrometer, which has the advantage of high adjustment accuracy.

[0094] In one specific implementation, such as Figure 1 and Figure 8 As shown, the gluing fixture also includes a fixing plate 1. The fixing plate 1 has a first fixing surface 1a and a second fixing surface 1b that are arranged opposite each other along the first direction X. The gluing mechanism 2 and the conveying mechanism 3 are both mounted on the first fixing surface 1a. A first support plate 11 extending along the first direction X is connected to the fixing plate 1. The gluing mechanism 2 is movably connected to the first support plate 11. The first direction X is perpendicular to the conveying direction of the electrode sheet and parallel to the axis of the supply roller 31 or the recovery roller 32.

[0095] The fixed plate 1 can support the glue application mechanism 2 through the first support plate 11, so that the glue application mechanism 2 can work stably during the glue application process; the fixed plate 1 can support the conveying mechanism 3, so that the conveying mechanism 3 can work stably during the glue application process.

[0096] Specifically, the first support plate 11 includes at least two, with at least two first support plates 11 spaced apart in the second direction Y. The conveying mechanism 3 includes multiple support rollers 33, which are disposed on both sides of the first support plate 11 along the conveying direction of the electrode sheet. They can provide tension to the electrode sheet and adjust the conveying direction of the electrode sheet, so that the electrode sheet is conveyed between the two first support plates 11. The two glue-applying mechanisms 2 on the two first support plates 11 can respectively apply glue to the first surface and the second surface of the electrode sheet. The second direction Y is perpendicular to the first direction X and perpendicular to the conveying direction of the electrode sheet.

[0097] like Figure 1As shown, the support roller 33 ensures that the electrode sheet 5 remains flat when passing through the coating mechanism 2, thereby improving the coating effect and preventing missed coating.

[0098] More specifically, such as Figure 8 As shown, the glue application mechanism 2 is disposed on the second support plate 12. The first support plate 11 and the second support plate 12 are connected by the second moving part 13, which can drive the second support plate 12 to move relative to the first support plate 11.

[0099] The second support plate 12 is L-shaped, with one end supporting the coating mechanism 2 and the other end connected to the second moving part 13. The second moving part 13 has two adjusting members, which can be adjusted to change the position of the coating mechanism 2 relative to the fixed plate 1 so that the coating roller 22 and the doctor blade roller 23 are located exactly below the junction of the active material area 51 and the empty foil area 52 of the electrode 5.

[0100] Specifically, the two adjusting components are a first micrometer 131 and a second micrometer 132. By adjusting the first micrometer 131, the position of the coating mechanism 2 along the second direction Y can be changed, thereby changing the distance between the coating roller 22, the doctor blade roller 23 and the electrode 5, so that the coating roller 22 can apply the adhesive to the electrode 5. By adjusting the second micrometer 132, the position of the coating mechanism 2 in the first direction X can be changed, so that the coating roller 22 and the doctor blade roller 23 can adapt to the width of the electrode 5.

[0101] like Figure 9 As shown, the conveying mechanism 3 further includes a second drive unit 34. The output end of the second drive unit 34 is connected to the supply roller 31 and the recovery roller 32, and can drive the supply roller 31 and the recovery roller 32 to rotate. The second drive unit 34 can be a motor with an output shaft. The output shaft is connected to the supply roller 31 and the recovery roller 32, and the motor drives the support roller 33 to rotate through the output shaft.

[0102] Understandably, the motors connected to the supply roller 31 and the take-up roller 32 should match the unwinding speed of the supply roller 31 and the winding speed of the take-up roller 32 to prevent the electrode sheet 5 from wrinkling or tearing.

[0103] like Figure 1 and Figure 10 As shown, the supply roller 31, the recovery roller 32 and the support roller 33 are mounted on the first fixed surface 1a, and the second drive unit 34 is mounted on the second fixed surface 1b, thereby avoiding the electrode sheet 5 and preventing the second drive unit 34 from affecting the smooth operation of the adhesive coating fixture.

[0104] In one specific embodiment, such as Figure 10As shown, the adhesive circulation mechanism 4 includes: an adhesive storage tank 41, a delivery pipe 42, and a drive pump 43. The adhesive storage tank 41 stores adhesive. The delivery pipe 42 is connected in a loop between the adhesive storage tank 41 and the adhesive application mechanism 2. The drive pump 43 is connected to the delivery pipe 42 and is used to drive the adhesive to flow in the delivery pipe 42. Along the direction of adhesive delivery, the drive pump 43 is located between the adhesive storage tank 41 and the adhesive application mechanism 2.

[0105] In this embodiment, as Figure 10 As shown, the drive pump 43 can create a vacuum, causing the adhesive to flow under negative pressure. Specifically, the adhesive in the storage roller 41 flows along the conveying pipe 42 through the drive pump 43 into the receiving tank 211 of the body 21. Then, the remaining adhesive flows out of the receiving tank 211 of the body 21 back into the conveying pipe 42 and returns to the storage tank 41. During this process, the adhesive remains in a flowing state and is less prone to solidification.

[0106] Specifically, the delivery pipe 42 is connected to the opening 213 of the main body 21. The drive pump 43 includes a pump body 431 and a third drive component 432, which drives the pump body 431 to work. The third drive component 432 can be a motor.

[0107] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
