Description

Technical Field

[0001] The present application belongs to the field of battery technology, and in particular relates to a material strip processing device and a roller cleaning method thereof. Background Art

[0002] With the development of new energy technology, batteries are used more and more widely, for example, in mobile phones, laptops, electric vehicles, electric cars, electric airplanes, electric ships, electric toy cars, electric toy ships, electric toy airplanes and electric tools, etc.

[0003] In the battery production process, how to improve the production rate and efficiency of flexible material strips such as pole pieces is a research direction in this field. Summary of the invention

[0004] The embodiment of the present application provides a material strip processing device and a roller cleaning method thereof, which is beneficial to improving the production quality and production efficiency of the material strip at a lower cost.

[0005] According to the first aspect of the present application, the present application embodiment provides a roller cleaning method for cleaning the roller, which is used to convey the material belt. The roller cleaning method provided by the present application embodiment includes: connecting the first material belt and the second material belt separated from each other along the running direction of the material belt by an adhesive tape, so that a part of the adhesive tape is located between the first material belt and the second material belt; and driving the first material belt, the second material belt and the adhesive tape to move the whole formed by the adhesive tape along the running direction, so that the adhesive tape passes through the roller and cleans the roller. The adhesive tape can stick to at least part of the impurities on the surface, so as to achieve the purpose of cleaning the roller, which is conducive to improving the production efficiency of the material belt. The present application does not need to configure a cleaning device for each roller separately, which is convenient for maintenance and reduces costs, and can reduce the number of downtimes and reduce manual participation, which is conducive to improving the production efficiency and production safety of the material belt. The adhesive tape is connected between the first material belt and the second material belt, which is conducive to reasonably selecting the length of the adhesive tape, improving the phenomenon that the adhesive tape is too long and easy to break, and is conducive to reducing the tension on the adhesive tape and reducing the possibility of the adhesive tape breaking, thereby helping to improve production efficiency.

[0006] In some embodiments, before the first and second material belts separated from each other are connected by the adhesive tape, the roller cleaning method further includes: cutting the material belt on the belt connection platform to form the first and second material belts; and moving at least one of the first and second material belts to separate the first and second material belts from each other along the belt running direction. This is conducive to flexibly selecting the cleaning time of the roller, and improving the timeliness and convenience of the roller cleaning.

[0007] In some embodiments, moving at least one of the first material belt and the second material belt includes: lifting a first belt pressing component on the belt connection platform for fixing the first material belt; using a first movably arranged adsorption mechanism to adsorb the first material belt and drive the first material belt to move in a direction away from the second material belt. The first belt pressing component can fix the first material belt, which is conducive to reducing the possibility of displacement of the first material belt; the first adsorption mechanism can adsorb and move the first material belt, which can reduce damage to the first material belt.

[0008] In some embodiments, moving at least one of the first material belt and the second material belt includes: lifting a second belt pressing component on the belt connection platform for fixing the second material belt; using a movably arranged first adsorption mechanism to adsorb the second material belt and drive the second material belt to move in a direction away from the first material belt. The second belt pressing component can fix the second material belt, which is conducive to reducing the possibility of displacement of the second material belt; the first adsorption mechanism can adsorb and move the second material belt, which can reduce damage to the second material belt.

[0009] In some embodiments, a first material tape and a second material tape separated from each other along the running direction of the material tape are connected by a tape, including: transferring a cleaning tape so that at least a portion of the cleaning tape is located between the first material tape and the second material tape; connecting the cleaning tape and the first material tape, and connecting the cleaning tape and the second material tape by a fixing tape; wherein the viscosity of the fixing tape is greater than the viscosity of the cleaning tape. The viscosity of the cleaning tape is relatively small, which can not only achieve the purpose of cleaning the roller, but also reduce the risk of the cleaning tape adhering to the roller and being difficult to separate from the roller, which is conducive to smoother running. In addition, sticky substances should not be retained on the surface of the roller, reducing the risk of sticky substances contaminating the material tape again. The viscosity of the fixing tape is relatively large, which is conducive to improving the connection strength, reducing the risk of disconnection between the cleaning tape and the material tape, and improving cleaning efficiency and production efficiency.

[0010] In some embodiments, the cleaning tape is connected to the first material tape by a fixing tape, and the cleaning tape is connected to the second material tape, including: bonding the first material tape and the cleaning tape by a first fixing tape; bonding the second material tape and the cleaning tape by a second fixing tape; and the first fixing tape and the second fixing tape are arranged at intervals along the tape running direction. Thus, the area of ​​the cleaning tape covered by the first fixing tape and the second fixing tape can be reduced, and the area of ​​the cleaning tape exposed to the outside can be increased, which is conducive to improving the cleaning effect of the cleaning tape on the roller.

[0011] In some embodiments, along the tape running direction, the cleaning tape and the first tape are spaced apart, and the cleaning tape and the second tape are spaced apart. This helps reduce the thickness of the tape adhesive portion, increases the effective cleaning area of ​​the cleaning tape, and reduces the risk of damaging the tape. In addition, during the process of transferring the cleaning tape to the first tape or the second tape, the cleaning tape is less likely to wrinkle, which helps keep the cleaning tape flat and improves its cleaning effect.

[0012] In some embodiments, a first gap is formed between the cleaning tape and the first material tape, and a second gap is formed between the cleaning tape and the second material tape. Along the tape running direction, the size of the first gap is d1, and the size of the second gap is d2; d1≤5mm, which can reduce the possibility of the first fixed tape sticking to the roller, which is beneficial to reducing the tape running tension and reducing the risk of tape breakage, and / or d2≤5mm, which can reduce the possibility of the second fixed tape sticking to the roller, which is beneficial to reducing the tape running tension and reducing the risk of tape breakage.

[0013] In some embodiments, the cleaning tape is bonded to the first material tape and / or the second material tape, thereby forming a double connection between the cleaning tape and the first material tape, and / or a double connection between the cleaning tape and the second material tape, which is beneficial to enhance the connection strength and reduce the risk of disconnection.

[0014] In some embodiments, a first material tape and a second material tape separated from each other along the running direction of the material tape are connected by tape so that a portion of the tape is located between the first material tape and the second material tape, including: transferring the starting end of the cleaning tape wound on the unwinding mechanism to the tape splicing platform; driving the gluing mechanism to apply the first fixing tape to the starting end of the cleaning tape and the first material tape, so as to connect the cleaning tape and the first material tape through the first fixing tape; driving the first material tape to drive the cleaning tape to move in a direction away from the second material tape until the cleaning tape on the tape splicing platform reaches a target length; cutting the cleaning tape; transferring the tail end formed after the cleaning tape is cut to the tape splicing platform; driving the gluing mechanism to apply the second fixing tape to the tail end of the cleaning tape and the second material tape, so as to connect the cleaning tape and the second material tape through the second fixing tape; wherein, the viscosity of the cleaning tape is less than that of the first fixing tape and the second fixing tape.

[0015] In some embodiments, before transferring the cleaning tape, the roller cleaning method further includes: peeling off the release paper covering the cleaning tape and rolling up the release paper. This facilitates peeling off the release paper from the cleaning tape, reduces the space occupied by the release paper, and is conducive to cleaning the production environment and is easy to recycle.

[0016] In some embodiments, both sides of the portion of the adhesive tape between the first material tape and the second material tape are sticky, so that the roller in contact with any side of the adhesive tape can be cleaned, and the cleaning range is wide, which is conducive to improving the cleaning efficiency and cleaning effect.

[0017] According to the second aspect of the present application, an embodiment of the present application provides a material strip processing device, which includes a roller and a roller cleaning device. The roller is used to convey the material strip; along the running direction of the material strip, the roller cleaning device is arranged upstream of the roller, and the roller cleaning device is used to clean the roller according to the roller cleaning method provided in any embodiment of the first aspect of the present application.

[0018] In some embodiments, the material strip processing equipment includes a tape splicing platform, the tape splicing platform is used for the adhesive tape to connect the first material strip and the second material strip, and at least part of the structure of the roller cleaning device is arranged on the tape splicing platform. Thus, the convenience of the operation of connecting the first material strip and the second material strip with the adhesive tape can be improved.

[0019] In some embodiments, the roller cleaning device includes a first cutting mechanism, which is disposed on the tape connection platform and is used to cut the material tape on the tape connection platform to form a first material tape and a second material tape. This is conducive to flexibly selecting the cleaning time of the roller, and improving the timeliness and convenience of the roller cleaning.

[0020] In some embodiments, the roller cleaning device includes a first belt pressing component, a second belt pressing component and a first adsorption mechanism. The first belt pressing component and the second belt pressing component are arranged on the belt connecting platform and are spaced apart along the belt running direction. The first belt pressing component is movably arranged along the thickness direction of the first material belt, and is used to selectively press or release the first material belt. The second belt pressing component is movably arranged along the thickness direction of the second material belt, and is used to selectively press or release the second material belt. The first adsorption mechanism is movably arranged along the belt running direction, and is used to selectively adsorb or release the first material belt and the second material belt. Thereby, the possibility of displacement of the first material belt and the second material belt is reduced. When the first belt pressing component releases the first material belt, the first material belt and / or the second material belt can be adsorbed and moved by the first adsorption mechanism, which can reduce damage to the first material belt and the second material belt.

[0021] In some embodiments, the tape includes a cleaning tape and a fixing tape; the roller cleaning device includes a second adsorption mechanism and a gluing mechanism. The second adsorption mechanism is used to selectively adsorb and transfer the cleaning tape or release the cleaning tape; the gluing mechanism is used to apply the fixing tape to connect the cleaning tape to the first tape and the cleaning tape to the second tape. This helps to reduce the risk of damaging the cleaning tape, improve the connection strength between the cleaning tape and the second tape, reduce the risk of tape breakage, and improve cleaning efficiency and production efficiency.

[0022] In some embodiments, the roller cleaning device includes an unwinding mechanism and a rewinding mechanism. The unwinding mechanism is used to unwind the cleaning tape wound thereon. The rewinding mechanism is used to peel off the release paper covering the cleaning tape and rewind the release paper. The cleaning tape is wound on the unwinding mechanism, which is convenient for storage and transportation, and is also convenient for unwinding the cleaning tape of a suitable length according to actual needs. The rewinding mechanism can exert a traction effect on the release paper, which is convenient for the release paper to be peeled off from the cleaning tape, and can also reduce the space occupied by the release paper, which is convenient for the cleanliness of the production environment and convenient for recycling.

[0023] In some embodiments, the roller cleaning device includes a second cutting mechanism disposed on the tape connection platform, and the second cutting mechanism is used to cut the cleaning tape, thereby reducing the possibility of dirtying the first cutting mechanism and extending the service life of the first cutting mechanism.

[0024] In some embodiments, the material strip processing equipment includes a slitting device, which is used to slit the material strip along the running direction of the material strip. Along the running direction of the material strip, the roller cleaning device is located upstream of the slitting device.

[0025] In some embodiments, the cleaning tape includes a plurality of adhesive portions having adhesive properties and at least one non-adhesive portion having no adhesive properties, the plurality of adhesive portions are arranged at intervals along the width direction of the cleaning tape, and two adjacent adhesive portions are connected by the non-adhesive portion; the width direction of the cleaning tape is perpendicular to the tape running direction. Thus, the possibility of adhesive substances adhering to the cutter can be reduced, which is beneficial to prolonging the service life of the slitting device.

[0026] In some embodiments, the cleaning tape includes a plurality of adhesive portions having stickiness, the plurality of adhesive portions are separately arranged along the width direction of the cleaning tape, and a gap is formed between two adjacent adhesive portions; the width direction of the cleaning tape is perpendicular to the tape running direction. Thus, the possibility of the sticky material adhering to the cutter can be reduced, which is conducive to extending the service life of the slitting device. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as those commonly understood by technicians in the technical field of this application; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" in the specification and claims of this application and the above-mentioned drawings and any variations thereof are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary and secondary relationship.

[0044] Reference to "embodiment" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments.

[0045] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "attached" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0046] The term "and / or" in this application is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this application generally indicates that the associated objects before and after are in an "or" relationship.

[0047] In the embodiments of the present application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width and other dimensions of various components in the embodiments of the present application shown in the drawings, as well as the overall thickness, length, width and other dimensions of the integrated device are only exemplary descriptions and should not constitute any limitation to the present application.

[0048] The term "plurality" used in the present application refers to two or more (including two).

[0049] In the embodiments of the present application, "parallel" includes not only the absolutely parallel situation, but also the roughly parallel situation conventionally recognized in engineering; at the same time, "vertical" includes not only the absolutely vertical situation, but also the roughly vertical situation conventionally recognized in engineering.

[0050] In the production process of batteries, rollers are usually used to convey material strips such as pole pieces to achieve support, die-cutting, and deviation correction of the material strips. After the rollers have been used for a period of time, the surface is prone to dirt. For example, dust in the air is adsorbed on the surface of the roller under the action of static electricity; for another example, when the material strip passes through the roller, impurities on the material strip adhere to the surface of the roller; for another example, the roller itself produces fine debris due to friction with the material strip or other objects. These impurities will adhere to the material strip passing through the roller, and even puncture the material strip, affecting the production quality of the material strip. The batteries produced have the risk of short circuits, affecting the production quality of the batteries.

[0051] In order to clean the roller, one feasible way is to wipe the roller manually by using dust-free paper or dust-free cloth dipped in water or alcohol. This method is not only time-consuming and labor-intensive, increasing costs, but also has the disadvantages of poor safety and incomplete wiping due to the narrow space between the rollers in the equipment, which also seriously affects the production efficiency of the material belt. Another feasible way is to use a retractable cleaning device to selectively contact the roller to clean the roller; however, each roller needs to be equipped with a cleaning device, which is costly and occupies a large space. The cleaning device itself also needs to be replaced, which is labor-intensive, and manual replacement also has safety issues.

[0052] In view of this, the embodiment of the present application provides a technical solution, which first connects the first material belt and the second material belt separated from each other along the running direction of the material belt through the adhesive tape, so that a part of the adhesive tape is located between the first material belt and the second material belt, and then drives the first material belt, the second material belt and the adhesive tape to form a whole to move along the running direction. When the adhesive tape passes through the downstream roller, the part of the adhesive tape located between the first material belt and the second material belt contacts the roller, which can adhere to at least part of the impurities on the surface of the roller, thereby achieving the purpose of cleaning the roller, which is conducive to improving the production efficiency of the material belt. This technical solution does not require a separate cleaning device for each roller, which is convenient for maintenance and reduces costs; and this technical solution cleans the rollers as the material belt travels, which can reduce the number of shutdowns, reduce manual participation, and is beneficial to improving the production efficiency and production safety of the material belt; the tape is connected between the first material belt and the second material belt, which is beneficial to reasonably selecting the length of the tape and improving the phenomenon that the tape is easily broken due to being too long, and the first material belt and the second material belt connected on both sides of the tape can serve as the main structure that bears the tension of the tape travel, which is beneficial to reducing the tension on the tape and reducing the possibility of the tape breaking, thereby helping to improve production efficiency.

[0053] The embodiment of the present application provides a roller cleaning method, which is used to clean a roller, and the roller is used to convey a material strip, which can be a pole piece or other strip-shaped material required in the battery production process.

[0054] The roller cleaning method provided in the embodiment of the present application is applicable to material strip processing equipment. For ease of understanding, the material strip processing equipment provided in the embodiment of the present application is first introduced in conjunction with the accompanying drawings.

[0055] Figure 1 is a schematic diagram of the structure of a strip processing device provided in some embodiments of the present application, Figures 2 to 5 They are Figure 1 The schematic diagram of the structure of the partial structure of the material strip processing equipment shown in the figure is a schematic diagram of the structure of the partial structure of the material strip processing equipment in different stages of the roller cleaning method. Figure 6 is a schematic top view of a partial structure of a strip processing device provided in some embodiments of the present application, Figure 7 It is a schematic top view of a partial structure of a material strip processing device provided in other embodiments of the present application.

[0056] Reference Figures 1 to 7 The material strip processing device 1 provided in the embodiment of the present application may include a roller 10, and the roller 10 is used to convey the material strip 2. The roller 10 may be one or more.

[0057] In some embodiments, the material strip processing device 1 may include a tape splicing platform 20, which is used to implement a tape splicing operation. Optionally, the tape splicing platform 20 can be used to implement the splicing between two material strips, the splicing between an adhesive tape and a material strip, and so on.

[0058] For example, in the embodiment of the present application, the tape splicing platform 20 is used to supply the adhesive tape 3 to connect the first material tape 201 and the second material tape 202. In other words, the tape splicing platform 20 can be used to achieve the splicing between the first material tape 201 and the adhesive tape 3, and the splicing between the adhesive tape 3 and the second material tape 202.

[0059] Along the running direction of the material strip, the strip connection platform 20 may be disposed upstream of the passing roller 10 .

[0060] In some embodiments, the material strip processing equipment 1 includes a roller cleaning device, and at least a portion of the structure of the roller cleaning device is disposed on the strip connection platform 20 .

[0061] The tape connection platform 20 may be one of the workstations of the tape processing equipment 1 , so as to arrange at least part of the structure of the roller cleaning device, thereby improving the operational convenience of connecting the first tape 201 and the second tape 202 with the adhesive tape 3 .

[0062] In some embodiments, the roller cleaning device includes a first cutting mechanism 37, which is disposed on the tape connection platform 20 and is used to cut the material tape 2 on the tape connection platform 20 to form a first material tape 201 and a second material tape 202. Thus, when the roller 10 needs to be cleaned, the material tape 2 can be cut by the first cutting mechanism 37, and the adhesive tape 3 can be continued at the cut end, which is conducive to flexibly selecting the cleaning time of the roller 10 and improving the timeliness and convenience of cleaning the roller 10.

[0063] Optionally, the first cutting mechanism 37 may include a driving component and a cutter, and the driving component can drive the cutter to move along the width direction of the material strip 2 to cut the material strip 2 .

[0064] In some embodiments, the roller cleaning device includes a first belt pressing component 31, a second belt pressing component 32 and a first adsorption mechanism 33. The first belt pressing component 31 and the second belt pressing component 32 are arranged on the belt connecting platform 20, and the first belt pressing component 31 and the second belt pressing component 32 are arranged at intervals along the belt running direction X. The first belt pressing component 31 is movably arranged along the thickness direction of the first material belt 201, and is used to selectively press or release the first material belt 201. The second belt pressing component 32 is movably arranged along the thickness direction of the second material belt 202, and is used to selectively press or release the second material belt 202. The first adsorption mechanism 33 is movably arranged along the belt running direction X, and is used to selectively adsorb or release the first material belt 201 and the second material belt 202.

[0065] The first belt-pressing component 31 can fix the first material belt 201 by pressing, clamping or other suitable methods. For example, the first belt-pressing component 31 can include a belt-pressing rod.

[0066] The second belt-pressing component 32 can fix the first material belt 201 by pressing, clamping or other suitable methods. For example, the second belt-pressing component 32 can include a belt-pressing rod.

[0067] The first adsorption mechanism 33 can adsorb the first material belt 201 or the second material belt 202 by vacuum adsorption, and drive the first material belt 201 or the second material belt 202 to move. After the first adsorption mechanism 33 breaks the vacuum, the first material belt 201 or the second material belt 202 can be released. Exemplarily, the first adsorption mechanism 33 may include a vacuum suction cup.

[0068] The embodiment of the present application fixes the first material belt 201 and the second material belt 202 respectively by the first belt pressing component 31 and the second belt pressing component 32, which is conducive to reducing the possibility of displacement of the first material belt 201 and the second material belt 202. When the first belt pressing component 31 releases the first material belt 201, the first adsorption mechanism 33 can adsorb and move the first material belt 201 and / or the second material belt 202, which can reduce damage to the first material belt 201 and the second material belt 202.

[0069] In some embodiments, the tape 3 includes a cleaning tape 301 and a fixing tape 302. The roller cleaning device includes a second adsorption mechanism 36 and a gluing mechanism 35. The second adsorption mechanism 36 is used to selectively adsorb and transfer the cleaning tape 301 or release the cleaning tape 301. The gluing mechanism 35 is used to apply the fixing tape 302 to connect the cleaning tape 301 with the first material tape 201, and to connect the cleaning tape 301 with the second material tape 202.

[0070] The second adsorption mechanism 36 can adsorb the cleaning tape 301 by vacuum adsorption and drive the cleaning tape 301 to move. After the second adsorption mechanism 36 breaks the vacuum, the cleaning tape 301 can be released. Exemplarily, the second adsorption mechanism 36 can include a vacuum suction cup.

[0071] The first adsorption mechanism 33 and the second adsorption mechanism 36 can be respectively located at the upper and lower sides of the belt connection platform 20, which is beneficial to shorten the moving distance of each adsorption mechanism, reduce the moving range of each adsorption mechanism, and reduce interference.

[0072] The glue attaching mechanism 35 may be disposed beside the tape splicing platform 20 , and the glue attaching mechanism 35 may be, for example, a glue attaching machine.

[0073] The second adsorption mechanism 36 fixes the cleaning tape 301 by adsorption and can move the cleaning tape 301 to the tape connection platform 20, which is helpful to reduce the risk of damaging the cleaning tape 301. The fixed tape 302 attached by the adhesive attachment mechanism 35 can improve the connection strength between the cleaning tape 301 and the second tape 202, reduce the risk of disconnection between the cleaning tape 301 and the first tape 201, and reduce the risk of disconnection between the cleaning tape 301 and the second tape 202, which is helpful to improve cleaning efficiency and production efficiency.

[0074] In some embodiments, the roller cleaning device includes an unwinding mechanism 34 and a rewinding mechanism 38. The unwinding mechanism 34 is used to unwind the cleaning tape 301 wound thereon. The rewinding mechanism 38 is used to peel off the release paper 303 covered on the cleaning tape 301 and rewind the release paper 303.

[0075] The cleaning tape 301 is wound on the unwinding mechanism 34, which is convenient for storage and transportation, and also convenient for unwinding the cleaning tape 301 of a suitable length according to actual needs.

[0076] The winding mechanism 38 can exert a traction effect on the release paper 303, which is conducive to peeling the release paper 303 off the cleaning tape 301. The winding mechanism 38 can also store the release paper, which can reduce the space occupied by the release paper 303, is conducive to the cleanliness of the production environment, and is easy to recycle.

[0077] In some embodiments, the roller cleaning device includes a second cutting mechanism 39 disposed on the tape splicing platform 20 , and the second cutting mechanism 39 is used to cut the cleaning tape 301 .

[0078] The second cutting mechanism 39 is used for cutting the cleaning tape 301 along the width direction of the cleaning tape 301 .

[0079] The second cutting mechanism 39 may include a driving component and a cutter, and the driving component drives the cutter along the width direction of the cleaning tape 301 to cut the cleaning tape 301 .

[0080] The embodiment of the present application utilizes the second cutting mechanism 39 to cut the cleaning tape 301, and utilizes the first cutting mechanism 37 to cut the material tape. The functions of the two cutting mechanisms are independently set, and the sticky substance of the cleaning tape 301 will not adhere to the first cutting mechanism 37, which is beneficial to reduce the possibility of dirtying the first cutting mechanism 37 and extend the service life of the first cutting mechanism 37.

[0081] In some embodiments, reference Figure 1 The material strip processing equipment 1 includes a slitting device 50, which is used to slit the material strip 2 along the running direction of the material strip 2. Along the running direction of the material strip 2, the roller cleaning device is located upstream of the slitting device 50.

[0082] The slitting device 50 can slit the material tape 2 along the running direction of the material tape 2 to divide the material tape 2 into a plurality of sub-material tapes. For example, the material tape 2 can be slit into two, three or more sub-material tapes.

[0083] The slitting device 50 may include a slitting drive mechanism and a blade, wherein the slitting drive mechanism is used to drive the blade to move close to or away from the material strip 2 to selectively slit the material strip 2. For example, when the material strip 2 needs to be slit, the slitting drive mechanism drives the blade to move close to the material strip 2 and contact the material strip 2; when the material strip 2 does not need to be slit, the slitting drive mechanism drives the blade to move away from the material strip 2 and separate from the material strip 2.

[0084] The roller cleaning device is located upstream of the slitting device 50, and can clean the rollers located between the roller cleaning device and the slitting device 50, as well as the rollers located downstream of the slitting device 50, which is beneficial to improving cleaning efficiency and saving cleaning time.

[0085] In some embodiments, reference Figure 6 and Figure 7 The cleaning tape 301 includes a plurality of adhesive portions 3011 having adhesive properties and at least one non-adhesive portion 3012 having no adhesive properties. The plurality of adhesive portions 3011 are arranged at intervals along the width direction Y of the cleaning tape 301, and two adjacent adhesive portions 3011 are connected by the non-adhesive portion 3012. The width direction Y of the cleaning tape 301 is perpendicular to the tape running direction X.

[0086] The adhesive portion 3011 is adhesive and can be adhered to the surface of the material strip 2 and can adhere to impurities. The non-adhesive portion 3012 is not adhesive and no significant adhesive force is generated between the non-adhesive portion 3012 and the structure in contact with it.

[0087] The number of the adhesive portions 3011 may be the same as the number of sub-material strips formed by slitting the material strip 2 by the slitting device 50 , and the number of the non-adhesive portions 3012 may be the same as the number of cutting lines of the slitting device 50 .

[0088] The non-adhesive portion 3012 may be a strip-shaped structure extending along the running direction of the material tape 2 , so as to reduce the size of the non-adhesive portion 3012 along the width direction of the material tape 2 and increase the size of the adhesive portion 3011 along the width direction of the material tape 2 .

[0089] The slitting device 50 can cut the material strip 2 along the area corresponding to the non-adhesive portion 3012 of the material strip 2, and avoid the adhesive portion 3011 on the material strip 2. The non-adhesive portion 3012 is non-adhesive, which can reduce the possibility of the adhesive material adhering to the cutter, which is conducive to extending the service life of the slitting device 50. Two adjacent adhesive portions 3011 are connected by the non-adhesive portion 3012, and the width of the non-adhesive portion 3012 remains unchanged, which can keep the interval distance between the two adjacent adhesive portions 3011 constant, and reduce the risk of the slitting device 50 cutting the adhesive portion 3011 due to the interval distance between the two adjacent adhesive portions 3011 fluctuating.

[0090] In other embodiments, the cleaning tape 301 includes a plurality of adhesive portions 3011 having adhesive properties, and the plurality of adhesive portions 3011 are separately arranged along the width direction Y of the cleaning tape 301, and a gap is formed between two adjacent adhesive portions 3011. The width direction Y of the cleaning tape 301 is perpendicular to the tape running direction X.

[0091] The slitting device 50 can cut the material strip 2 along the area corresponding to the gap between the material strip 2 and avoid the adhesive portion 3011 on the material strip 2. There is no adhesive substance in the gap, which can reduce the possibility of the adhesive substance adhering to the cutter, which is beneficial to extending the service life of the slitting device 50. No other structure is set between two adjacent adhesive portions 3011, and the two adjacent adhesive portions 3011 are set independently of each other, which is beneficial to saving materials and reducing costs.

[0092] Figure 8 Schematic diagram of the flow of the roller cleaning method provided in some embodiments of the present application. Figure 8 The roller cleaning method provided in the embodiment of the present application includes:

[0093] Step S20, connecting the first material tape 201 and the second material tape 202 separated from each other along the tape running direction X by means of the adhesive tape 3, so that a part of the adhesive tape 3 is located between the first material tape 201 and the second material tape 202; and

[0094] Step S40 , driving the whole formed by the first material tape 201 , the second material tape 202 and the adhesive tape 3 to move along the tape running direction X, so that the adhesive tape 3 passes through the roller 10 , and the roller 10 is cleaned.

[0095] The first material strip 201 and the second material strip 202 can be two sections of material strips formed by cutting a material strip that is supplied as an integral material, or can be two material strips that are supplied as separate materials.

[0096] The first material tape 201 and the second material tape 202 are separated from each other along the tape running direction X, which means that the first material tape 201 and the second material tape 202 are arranged at intervals along the tape running direction X so that a certain gap is formed between the first material tape 201 and the second material tape 202 .

[0097] After the adhesive tape 3 connects the first material tape 201 and the second material tape 202 , a portion of the adhesive tape 3 may be located between the first material tape 201 and the second material tape 202 , and may be exposed to the outside through the gap between the first material tape 201 and the second material tape 202 , so as to contact the roller 10 .

[0098] The gap between the first material belt 201 and the second material belt 202 has a predetermined size, so that the portion of the adhesive tape 3 between the first material belt 201 and the second material belt 202 has a predetermined length, which is beneficial to improving the cleaning effect of the adhesive tape 3 on the roller 10 .

[0099] Along the running direction X, the first material tape 201 may be located upstream of the second material tape 202 , or may be located downstream of the second material tape 202 .

[0100] In step S20 , the adhesive tape 3 may be bonded to the first material tape 201 and the second material tape 202 at the same time, or may be bonded to one of the first material tape 201 and the second material tape 202 first, and then bonded to the other of the first material tape 201 and the second material tape 202 .

[0101] In step S40 , the upstream one of the first material belt 201 and the second material belt 202 may be driven to move along the running direction X to pull the adhesive tape 3 and the downstream one of the first material belt 201 and the second material belt 202 to move along the running direction X.

[0102] At least one side of the portion of the adhesive tape 3 between the first material tape 201 and the second material tape 202 is sticky and can adhere to impurities such as metal particles, burrs, hair, and dust.

[0103] When the adhesive tape 3 passes through the downstream roller 10, the portion of the adhesive tape 3 located between the first material belt 201 and the second material belt 202 contacts the roller 10. The adhesive effect of the adhesive tape 3 on the impurities on the surface of the roller 10 is greater than the attachment effect between the roller 10 and the impurities. The adhesive tape 3 can stick to at least part of the impurities on the surface of the roller 10, thereby achieving the purpose of cleaning the roller 10, which is beneficial to improving the production efficiency of the material belt.

[0104] The embodiment of the present application does not need to configure a cleaning device for each roller 10 separately, which is convenient for maintenance and reduces costs. The embodiment of the present application cleans the roller 10 as the material belt is running, which can reduce the number of shutdowns and reduce manual participation, which is beneficial to improving the production efficiency and production safety of the material belt. More importantly, the tape 3 is connected between the first material belt 201 and the second material belt 202, which is beneficial to reasonably select the length of the tape 3 and improve the phenomenon that the tape 3 is too long and easy to break. In addition, the first material belt 201 and the second material belt 202 connected on both sides of the tape 3 can serve as the main structure to bear the tension of the running belt, which is beneficial to reduce the tension on the tape 3 and reduce the possibility of the tape 3 breaking, which is beneficial to improve production efficiency.

[0105] Fig. 9 Schematic diagram of the flow of the roller cleaning method provided by other embodiments of the present application. Fig. 9 In some embodiments, before connecting the first material belt 201 and the second material belt 202 separated from each other by the adhesive tape 3, the roller cleaning method of the embodiment of the present application further includes:

[0106] Step S110, cutting the material tape 2 on the tape splicing platform 20 to form a first material tape 201 and a second material tape 202; and

[0107] In step S120 , at least one of the first material tape 201 and the second material tape 202 is moved so that the first material tape 201 and the second material tape 202 are separated from each other along the running direction X.

[0108] The first material strip 201 and the second material strip 202 are two sections of material strips formed after the material strip 2 is cut.

[0109] In step S110 , the material tape 2 may be cut along its width direction, which is perpendicular to the tape running direction X, to facilitate connection between the first material tape 201 and the adhesive tape 3 , and between the second material tape 202 and the adhesive tape 3 .

[0110] In step S120, the first material tape 201 may be moved away from the second material tape 202, the second material tape 202 may be moved away from the first material tape 201, or the first material tape 201 and the second material tape 202 may be moved in opposite directions simultaneously or sequentially.

[0111] The belt splicing platform 20 can be one of the workstations of the material belt processing equipment 1. When there is no need to clean the roller 10, the material belt 2 can pass through the belt splicing platform 20 workstation normally. When the roller 10 needs to be cleaned, the material belt 2 can be cut at the belt splicing platform 20 workstation and the tape 3 can be extended at the cut end, which is conducive to flexible selection of the cleaning time of the roller 10 and improves the timeliness and convenience of cleaning the roller 10.

[0112] In some embodiments, moving at least one of the first material belt 201 and the second material belt 202 may specifically include:

[0113] Lift the first tape pressing component 31 on the tape splicing platform 20 for fixing the first material tape 201;

[0114] The first movably disposed first adsorption mechanism 33 adsorbs the first material belt 201 and drives the first material belt 201 to move in a direction away from the second material belt 202 .

[0115] It can be understood that before at least one of the first material belt 201 and the second material belt 202 is moved, the first belt pressing component 31 is in a state of fixing the first material belt 201 .

[0116] Before cutting the material strip 2, the material strip 2 may be first pressed by the tape pressing component to reduce the risk of the material strip 2 shifting during the cutting process. Optionally, the material strip 2 may be pressed by the first tape pressing component 31 to form a portion of the first material strip 201.

[0117] After the first adsorption mechanism 33 drives the first material belt 201 to move to a suitable position, the first material belt 201 can be fixed again by the first belt pressing component 31 to reduce the risk of displacement of the first material belt 201 during the subsequent connection process with the adhesive tape 3.

[0118] The embodiment of the present application fixes the first material belt 201 by the first pressing belt component 31, which is beneficial to reduce the possibility of displacement of the first material belt 201; after the first pressing belt component 31 releases the first material belt 201, the first adsorption mechanism 33 adsorbs and moves the first material belt 201, which can reduce damage to the first material belt 201.

[0119] In some embodiments, moving at least one of the first material belt 201 and the second material belt 202 may specifically include:

[0120] Lift the second tape pressing component 32 on the tape splicing platform 20 for fixing the second material tape 202;

[0121] The movably arranged first adsorption mechanism 33 adsorbs the second material belt 202 and drives the second material belt 202 to move in a direction away from the first material belt 201 .

[0122] It can be understood that before at least one of the first material belt 201 and the second material belt 202 is moved, the second belt pressing component 32 is in a state of fixing the second material belt 202 .

[0123] The second belt-pressing component 32 can fix the second material belt 202 by pressing, clamping or other suitable methods. For example, the second belt-pressing component 32 can include a belt-pressing rod.

[0124] Before cutting the material strip 2, the material strip 2 may be fixed by the tape pressing component to reduce the risk of the material strip 2 shifting during the cutting process. Optionally, the material strip 2 may be fixed by the second tape pressing component 32 to form the portion of the second material strip 202.

[0125] After the first adsorption mechanism 33 drives the second material belt 202 to move to a suitable position, the second material belt 202 can be fixed again by the second belt pressing component 32 to reduce the risk of displacement of the second material belt 202 during the subsequent connection process with the adhesive tape 3.

[0126] The embodiment of the present application fixes the second material belt 202 by the second pressing belt component 32, which is helpful to reduce the possibility of displacement of the second material belt 202; after the second pressing belt component 32 releases the second material belt 202, the first adsorption mechanism 33 adsorbs and moves the second material belt 202, which can reduce damage to the second material belt 202.

[0127] In some embodiments, one of the first material belt 201 and the second material belt 202 may be moved by the first adsorption mechanism 33 first, and then the other of the first material belt 201 and the second material belt 202 may be moved by the first adsorption mechanism 33. Adjusting the positions of the first material belt 201 and the second material belt 202 by moving the first adsorption mechanism 33 is conducive to simplifying the structure.

[0128] Fig.10 1 is a flow chart of connecting a first material belt and a second material belt separated from each other along the belt running direction by an adhesive tape in a roller cleaning method provided in some embodiments of the present application. Fig.10 In some embodiments, the first material tape 201 and the second material tape 202 separated from each other along the tape running direction X are connected by the adhesive tape 3, which may specifically include:

[0129] Step S201, moving the cleaning tape 301 so that at least a portion of the cleaning tape 301 is located between the first material tape 201 and the second material tape 202; and

[0130] Step S202 , connecting the cleaning tape 301 and the first material tape 201 by means of the fixing tape 302 , and connecting the cleaning tape 301 and the second material tape 202 .

[0131] The viscosity of the fixing tape 302 is greater than that of the cleaning tape 301 .

[0132] The cleaning tape 301 is mainly used for cleaning the roller 10 , and the fixing tape 302 is mainly used for connecting the first material tape 201 and the second material tape 202 .

[0133] In step S201, the cleaning tape 301 can be a section, and the length of the cleaning tape 301 along the tape running direction X matches the spacing between the first material tape 201 and the second material tape 202. At this time, the cleaning tape 301 can be moved as a whole so that at least part of the cleaning tape 301 is located between the first material tape 201 and the second material tape 202.

[0134] In step S201, the beginning of the wound cleaning tape 301 may also be transferred. After the cleaning tape 301 is unwound to a length matching the spacing between the first material tape 201 and the second material tape 202 by pulling, unwinding or other suitable means, the cleaning tape 301 is cut.

[0135] The cleaning tape 301 may be located entirely between the first material tape 201 and the second material tape 202, or only a portion of the cleaning tape 301 may be located between the first material tape 201 and the second material tape 202. For example, a portion of the cleaning tape 301 may overlap with the first material tape 201, and a portion of the cleaning tape 301 may overlap with the second material tape 202.

[0136] The cleaning tape 301 and the first material tape 201 may be connected only indirectly through the fixing tape 302, or they may be directly connected and indirectly connected through the fixing tape 302. The cleaning tape 301 and the second material tape 202 may be connected only indirectly through the fixing tape 302, or they may be directly connected and indirectly connected through the fixing tape 302.

[0137] The fixing tape 302 may have one side that is sticky, and the sticky side of the fixing tape 302 is bonded to the cleaning tape 301, the first material tape 201, and the second material tape 202. The fixing tape 302 has one side that is sticky, which can reduce the contact between the sticky substance of the fixing tape 302 and the roller 10, and reduce the adverse effect of the fixing tape 302 on the roller 10.

[0138] The stickiness of the fixing tape 302 is greater than the stickiness of the cleaning tape 301, which means that the adhesion of the fixing tape 302 to the contact object is greater than the adhesion of the cleaning tape 301 to the same contact object. In other words, the bonding strength between the fixing tape 302 and the contact object is greater than the bonding strength between the cleaning tape 301 and the same contact object.

[0139] Impurities on the roller 10 are usually attached to the roller surface due to static electricity, gravity or other effects, and can be separated from the roller 10 with only a small external force. Therefore, the cleaning tape 301 used to contact the roller 10 has a relatively low viscosity, which can not only remove at least part of the impurities on the roller surface of the roller 10 to achieve the purpose of cleaning the roller 10, but also reduce the risk of the cleaning tape 301 adhering to the roller 10 and being difficult to separate from the roller 10, which is conducive to smoother tape running of the first material belt 201, the second material belt 202 and the tape 3. In addition, the cleaning tape 301 has a low viscosity, and the sticky substance of the cleaning tape 301 is not easy to stay on the surface of the roller 10, reducing the risk of the sticky substance contaminating the material belt 2 again.

[0140] The fixing tape 302 has relatively strong viscosity, which is beneficial to improving the connection strength between the cleaning tape 301 and the first tape 201, improving the connection strength between the cleaning tape 301 and the second tape 202, reducing the risk of disconnection between the cleaning tape 301 and the first tape 201, reducing the risk of disconnection between the cleaning tape 301 and the second tape 202, and helping to improve cleaning efficiency and production efficiency.

[0141] In some embodiments, the cleaning tape 301 is connected to the first material tape 201 by the fixing tape 302, and the cleaning tape 301 is connected to the second material tape 202, including:

[0142] Bonding the first material tape 201 and the cleaning tape 301 by the first fixing tape 3021; ​​and

[0143] The second material tape 202 and the cleaning tape 301 are bonded together by the second fixing tape 3022;

[0144] Along the tape running direction X, the first fixing tape 3021 and the second fixing tape 3022 are arranged at intervals.

[0145] In step S202, the first material tape 201 and the cleaning tape 301 can be first bonded by the first fixing tape 3021, and then the second material tape 202 and the cleaning tape 301 can be bonded by the second fixing tape 3022; or the second material tape 202 and the cleaning tape 301 can be first bonded by the second fixing tape 3022, and then the first material tape 201 and the cleaning tape 301 can be bonded by the first fixing tape 3021.

[0146] The first fixing tape 3021 is attached and bonded to the same side surface of the first material tape 201 and the cleaning tape 301, thereby connecting the first material tape 201 and the cleaning tape 301. The second fixing tape 3022 is attached and bonded to the same side surface of the second material tape 202 and the cleaning tape 301, thereby connecting the second material tape 202 and the cleaning tape 301.

[0147] The first fixing tape 3021 and the second fixing tape 3022 are located on the same side of the cleaning tape 301 , or they may be located on both sides of the cleaning tape 301 .

[0148] In step S202, the first fixing tape 3021 may be attached along the width direction of the first material tape 201, and the second fixing tape 3022 may be attached along the width direction of the second material tape 202. The width direction of the first material tape 201 and the width direction of the second material tape 202 are both perpendicular to the running direction X.

[0149] Along the width direction of the first material tape 201 , both ends of the first fixing tape 3021 do not extend beyond the cleaning tape 301 . Along the width direction of the second material tape 202 , both ends of the second fixing tape 3022 do not extend beyond the cleaning tape 301 .

[0150] The size of the first fixing tape 3021 along the tape running direction X is the same as the size of the second fixing tape 3022 along the tape running direction X, and the first fixing tape 3021 and the second fixing tape 3022 can be applied by the same adhesive application mechanism.

[0151] The first fixing tape 3021 and the second fixing tape 3022 are arranged at intervals, which can reduce the area of ​​the cleaning tape 301 covered by the first fixing tape 3021 and the second fixing tape 3022 and increase the area of ​​the cleaning tape 301 exposed to the outside, which is beneficial to improving the cleaning effect of the cleaning tape 301 on the roller 10.

[0152] In some embodiments, along the tape running direction X, the cleaning tape 301 and the first tape 201 are spaced apart, and the cleaning tape 301 and the second tape 202 are spaced apart. The cleaning tape 301 is located between the first tape 201 and the second tape 202.

[0153] The first fixing tape 3021 and the cleaning tape 301 partially overlap, and the first fixing tape 3021 and the first material tape 201 partially overlap; the first fixing tape 3021 can cover the end of the first material tape 201 adjacent to the cleaning tape 301, and cover the end of the cleaning tape 301 adjacent to the first material tape 201, and the first fixing tape 3021 can also cover the gap between the first material tape 201 and the cleaning tape 301.

[0154] The second fixing tape 3022 partially overlaps with the cleaning tape 301, and the second fixing tape 3022 partially overlaps with the second material tape 202; the second fixing tape 3022 can cover the end of the cleaning tape 301 adjacent to the second material tape 202, and cover the end of the second material tape 202 adjacent to the cleaning tape 301, and the second fixing tape 3022 can also cover the gap between the second material tape 202 and the cleaning tape 301.

[0155] If the thickness of some areas of the tape after gluing is too thick, a step will be formed between this area and other adjacent areas, causing the part of the cleaning tape 301 close to the step to be unable to contact the roller 10, reducing the effective cleaning area of ​​the cleaning tape 301, and the step may also affect the flatness of the tape or even damage the tape.

[0156] To this end, the embodiment of the present application sets the cleaning tape 301 at intervals from the first material tape 201 and the second material tape 202, so that there will be no overlap between the cleaning tape 301, the first material tape 201 and the first fixing tape 3021, and there will be no overlap between the cleaning tape 301, the second material tape 202 and the second fixing tape 3022, which is conducive to reducing the thickness of the adhesive portion of the material tape, increasing the effective cleaning area of ​​the cleaning tape 301, and reducing the risk of damaging the material tape. In addition, during the process of transferring the cleaning tape 301 to the first material tape 201 or the second material tape 202, the cleaning tape 301 is not prone to wrinkles, which is conducive to keeping the cleaning tape 301 flat and improving its cleaning effect.

[0157] In some embodiments, a first gap 401 is formed between the cleaning tape 301 and the first material tape 201, and a second gap 402 is formed between the cleaning tape 301 and the second material tape 202. Along the tape running direction X, the size of the first gap 401 is d1, and the size of the second gap 402 is d2. d1≤5mm, and / or d2≤5mm.

[0158] The first fixing tape 3021 is used to connect the cleaning tape 301 and the first material tape 201. The first fixing tape 3021 is usually highly sticky. The first fixing tape 3021 covers the first gap 401. The portion of the first fixing tape 3021 corresponding to the first gap 401 is exposed, and the portion is in contact with the roller 10. If the size of d1 is too large, the contact area between the first fixing tape 3021 and the roller 10 is too large, and the first fixing tape 3021 is easily stuck to the roller 10, and is not easy to separate from the roller 10.

[0159] To this end, in the embodiment of the present application, d1 is set to be less than or equal to 5 mm, which can reduce the possibility of the first fixing tape 3021 sticking to the roller 10, which is beneficial to reducing the tape tension and the risk of tape breakage.

[0160] Similarly, if the size of d2 is too large, the contact area between the second fixing tape 3022 and the roller 10 is too large, and the second fixing tape 3022 is easily stuck to the roller 10 and is difficult to separate from the roller 10 .

[0161] To this end, the embodiment of the present application sets d2 to be less than or equal to 5 mm, which can reduce the possibility of the second fixing tape 3022 sticking to the roller 10, which is beneficial to reducing the tape tension and the risk of tape breakage.

[0162] In some embodiments, the cleaning tape 301 is bonded to the first material tape 201 and / or the second material tape 202 .

[0163] The cleaning tape 301 can be bonded to the first material tape 201, and there is an overlap between the cleaning tape 301 and the first material tape 201. The first fixing tape 3021 covers the end of the cleaning tape 301 adjacent to the first material tape 201 or covers the end of the first material tape 201 adjacent to the cleaning tape 301, and is bonded to the same side surface of the cleaning tape 301 and the first material tape 201.

[0164] The cleaning tape 301 can be bonded to the second tape 202, and there is an overlap between the cleaning tape 301 and the second tape 202. The second fixing tape 3022 covers the end of the cleaning tape 301 adjacent to the second tape 202 or covers the end of the second tape 202 adjacent to the cleaning tape 301, and is bonded to the same side surface of the cleaning tape 301 and the second tape 202.

[0165] The cleaning tape 301 can also be bonded to the first material tape 201 and the second material tape 202 at the same time.

[0166] The cleaning tape 301 is directly bonded to the first material tape 201. There is bonding between the cleaning tape 301 and the first material tape 201. The first fixing tape 3021 is used to strengthen the connection between the cleaning tape 301 and the first material tape 201. A double connection is formed between the cleaning tape 301 and the first material tape 201, which is beneficial to enhance the connection strength and reduce the risk of disconnection.

[0167] The cleaning tape 301 is directly bonded to the second material tape 202. There is a bonding effect between the cleaning tape 301 and the second material tape 202. The second fixing tape 3022 is used to strengthen the connection between the cleaning tape 301 and the second material tape 202. A double connection is formed between the cleaning tape 301 and the second material tape 202, which is beneficial to enhance the connection strength and reduce the risk of disconnection.

[0168] Fig.11 1 is a schematic flow chart of connecting a first material belt and a second material belt separated from each other along the belt running direction by an adhesive tape in a roller cleaning method provided in other embodiments of the present application. Fig.11 In some embodiments, a first material tape 201 and a second material tape 202 separated from each other along a tape running direction X are connected by an adhesive tape 3 so that a portion of the adhesive tape 3 is located between the first material tape 201 and the second material tape 202, including:

[0169] Step S211, the beginning of the cleaning tape 301 wound on the unwinding mechanism 34 is transferred to the tape splicing platform 20 (refer to Figure 3 );

[0170] Step S212, driving the adhesive attaching mechanism 35 to attach the first fixing tape 3021 to the starting end of the cleaning tape 301 and the first material tape 201, so as to connect the cleaning tape 301 and the first material tape 201 through the first fixing tape 3021 (refer to Figure 4 );

[0171] Step S213, driving the first material tape 201 to drive the cleaning tape 301 to move in a direction away from the second material tape 202 until the cleaning tape 301 on the tape connection platform 20 reaches a target length;

[0172] Step S214, cutting the cleaning tape 301;

[0173] Step S215, moving the tail end of the cleaning tape 301 formed after being cut to the tape splicing platform 20; and

[0174] Step S216, driving the adhesive attaching mechanism 35 to attach the second fixing tape 3022 to the tail end of the cleaning tape 301 and the second material tape 202, so as to connect the cleaning tape 301 and the second material tape 202 through the second fixing tape 3022 (refer to Figure 5 ).

[0175] The viscosity of the cleaning tape 301 is smaller than the viscosity of the first fixing tape 3021 and the viscosity of the second fixing tape 3022 .

[0176] The cleaning tape 301 on the tape splicing platform 20 reaches the target length, which means that the cleaning tape 301 on the tape splicing platform 20 matches the spacing distance between the first material tape 201 and the second material tape 202 .

[0177] The length of the cleaning tape 301 on the tape splicing platform 20 refers to the length of the cleaning tape 301 used to connect with the first material tape 201 and the second material tape 202 on the tape splicing platform 20 .

[0178] After the cleaning tape 301 on the tape splicing platform 20 reaches the target length, the movement of the first material tape 201 is stopped.

[0179] The starting end of the cleaning tape 301 is the end of the cleaning tape 301 in the rolled state that is on the outside.

[0180] In step S211 , the second movably disposed adsorption mechanism 36 may be used to adsorb the cleaning tape 301 , and drive the beginning of the cleaning tape 301 to move to the tape connection platform 20 .

[0181] The first adsorption mechanism 33 and the second adsorption mechanism 36 may be located at upper and lower sides of the tape connection platform 20 , respectively.

[0182] After step S211 and before step S212, the roller cleaning method of the embodiment of the present application may also include: using a movably arranged first adsorption mechanism 33 to adsorb the cleaning tape 301; controlling the second adsorption mechanism 36 to release the cleaning tape 301 and move out of the tape connection platform 20 to reduce the possibility of interference between the second adsorption mechanism 36 and the glue application mechanism 25.

[0183] In step S215, the second suction mechanism 36 can be used to suck the tail end of the cleaning tape 301, and the tail end of the cleaning tape 301 can be moved to the tape splicing platform 20. Afterwards, the first suction mechanism 33 can be used to suck the tail end of the cleaning tape 301, and the second suction mechanism 36 can be controlled to release the cleaning tape 301 and move out of the tape splicing platform 20, so as to reduce the possibility of interference between the second suction mechanism 36 and the adhesive bonding mechanism 25.

[0184] In some embodiments, before transferring the cleaning tape, the roller cleaning method of the embodiment of the present application further includes: peeling off the release paper 303 covering the cleaning tape 301 , and rolling up the release paper 303 .

[0185] The release paper 303 can isolate and protect the cleaning tape 301 , so that the cleaning tape 301 can be wound on the unwinding mechanism 34 , which is beneficial to the storage and transportation of the cleaning tape 301 .

[0186] The winding arrangement of the release paper 303 is conducive to peeling the release paper 303 off the cleaning tape 301 and can reduce the space occupied by the release paper 303, which is conducive to the cleanliness of the production environment and is convenient for recycling.

[0187] In some embodiments, both sides of the portion of the adhesive tape 3 between the first material tape 201 and the second material tape 202 are adhesive.

[0188] When the adhesive tape 3 moves, it does not only keep one side in contact with the roller 10. For example, when the first material belt 201, the second material belt 202 and the adhesive tape 3 are reversed as a whole, the surfaces of the adhesive tape 3 in contact with different rollers 10 are also different.

[0189] In the embodiment of the present application, both sides of the portion of the tape 3 between the first material tape 201 and the second material tape 202 are configured to be sticky, so that the roller 10 in contact with any side of the tape 3 can be cleaned, and the cleaning range is wider, which is beneficial to improving the cleaning efficiency and cleaning effect.

[0190] The embodiment of the present application also provides a material strip processing device 1, which includes a roller 10 and a roller cleaning device. The roller 10 is used to convey the material strip 2. The roller cleaning device is arranged upstream of the roller 10 along the running direction of the material strip 2. The roller cleaning device is used to clean the roller 10 according to the roller cleaning method provided in any embodiment of the present application.

[0191] The material belt processing equipment 1 provided in the embodiment of the present application does not need to be equipped with a cleaning device for each roller 10 separately, which is convenient for maintenance and reduces costs. The roller cleaning device cleans the roller 10 as the material belt travels, which can reduce the number of shutdowns and reduce manual participation, which is beneficial to improving the production efficiency and production safety of the material belt. More importantly, the adhesive tape 3 is connected between the first material belt 201 and the second material belt 202, which is beneficial to reasonably select the length of the adhesive tape 3 and improve the phenomenon that the adhesive tape 3 is too long and easy to break. In addition, the first material belt 201 and the second material belt 202 connected on both sides of the adhesive tape 3 can be used as the main structure to bear the tension of the tape travel, which is beneficial to reduce the tension on the adhesive tape 3 and reduce the possibility of the adhesive tape 3 breaking, thereby helping to improve production efficiency.

[0192] The roller cleaning method provided by the embodiment of the present application includes: cutting the material tape 2 on the tape splicing platform 20 to form a first material tape 201 and a second material tape 202; moving at least one of the first material tape 201 and the second material tape 202 so that the first material tape 201 and the second material tape 202 are separated from each other along the tape running direction X; moving the starting end of the cleaning tape 301 wound on the unwinding mechanism 34 to the tape splicing platform; driving the adhesive sticking mechanism 35 to stick the first fixing tape 3021 to the starting end of the cleaning tape 301 and the first material tape 201, so as to pass the first fixing tape 3021 through the first fixing tape 30 21 connects the cleaning tape 301 and the first material tape 201; drives the first material tape 201 to drive the cleaning tape 301 to move in the direction away from the second material tape 202 until the cleaning tape 301 located on the tape splicing platform 20 reaches the target length; cuts the cleaning tape 301; moves the tail end of the cleaning tape 301 formed after being cut to the tape splicing platform 20; drives the adhesive sticking mechanism 35 to stick the second fixing tape 3022 to the tail end of the cleaning tape 301 and the second material tape 202, so as to connect the cleaning tape 301 and the second material tape 202 through the second fixing tape 3022.

[0193] The cleaning tape 301 includes a plurality of adhesive portions 3011 having adhesive properties and at least one non-adhesive portion 3012 having no adhesive properties, wherein the plurality of adhesive portions 3011 are arranged at intervals along the width direction Y of the cleaning tape 301, and two adjacent adhesive portions 3011 are connected via the non-adhesive portion 3012. Alternatively, the cleaning tape 301 includes a plurality of adhesive portions 3011 having adhesive properties, wherein the plurality of adhesive portions 3011 are arranged at intervals along the width direction Y of the cleaning tape 301, and a gap is formed between two adjacent adhesive portions 3011.
