[0001] The application belongs to the technical field of batteries, and particularly relates to a material belt processing device and a method for cleaning a passing roller. BACKGROUND

[0002] With the development of new energy technology, batteries are increasingly widely applied, such as in mobile phones, notebook computers, electric vehicles, electric cars, electric aircraft, electric ships, electric toy cars, electric toy ships, electric toy aircraft, and electric tools.

[0003] In a battery production process, how to improve the production yield and production efficiency of flexible material belts such as electrode sheets is a research direction in the field. SUMMARY

[0004] The application provides a material belt processing device and a method for cleaning a passing roller, which is beneficial to improving the production yield and production efficiency of material belts at a low cost.

[0005] According to a first aspect of the application, the application provides a method for cleaning a passing roller, which is used to convey a material belt. The method comprises: connecting a first material belt and a second material belt, which are separated from each other along a belt running direction of the material belt, by a tape, so that a part of the tape is located between the first material belt and the second material belt; and driving the whole formed by the first material belt, the second material belt, and the tape to move along the belt running direction, so that the tape passes through the passing roller and the passing roller is cleaned. The tape can stick at least part of impurities on the surface of the passing roller, so as to achieve the purpose of cleaning the passing roller and improve the production yield of the material belt. The application does not need to separately configure a cleaning device for each passing roller, which is convenient for maintenance and reduces the cost, and can reduce the number of shutdowns, reduce manual participation, and improve 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, improving the phenomenon that the tape is easily broken due to too long length, reducing the tension on the tape, and reducing the possibility of tape breakage, thereby improving the production efficiency.

[0006] In some embodiments, before connecting the first material belt and the second material belt, which are separated from each other by the tape, the method for cleaning the passing roller further comprises: cutting the material belt on a belt connecting platform to form the first material belt and the second material belt; and moving at least one of the first material belt and the second material belt, so that the first material belt and the second material belt are separated from each other along the belt running direction. Thus, it is beneficial to flexibly select the cleaning time of the passing roller and improve the timeliness and convenience of cleaning the passing roller.

[0007] In some embodiments, moving at least one of the first material strip and the second material strip includes: lifting a first strip fixing component on the strip receiving platform for fixing the first material strip; and using a first movable suction mechanism to suck and move the first material strip away from the second material strip. The first strip fixing component can fix the first material strip, which can reduce the possibility of displacement of the first material strip; and the first suction mechanism can suck and move the first material strip, which can reduce damage to the first material strip.

[0008] In some embodiments, moving at least one of the first material strip and the second material strip includes: lifting a second strip fixing component on the strip receiving platform for fixing the second material strip; and using a first movable suction mechanism to suck and move the second material strip away from the first material strip. The second strip fixing component can fix the second material strip, which can reduce the possibility of displacement of the second material strip; and the first suction mechanism can suck and move the second material strip, which can reduce damage to the second material strip.

[0009] In some embodiments, connecting the first material strip and the second material strip, which are separated from each other along the strip moving direction of the material strip by the cleaning tape, includes: moving the cleaning tape to at least partially position the cleaning tape between the first material strip and the second material strip; and connecting the cleaning tape and the first material strip by a fixing tape and connecting the cleaning tape and the second material strip by the fixing tape, wherein the fixing tape has a greater adhesive property than the cleaning tape. The cleaning tape has a relatively small adhesive property, which can achieve the purpose of cleaning the roller and reduce the risk of the cleaning tape being difficult to separate from the roller after being attached to the roller, so as to facilitate smoother strip moving. In addition, the adhesive substance is not likely to stay on the surface of the roller, which reduces the risk of the adhesive substance again contaminating the material strip. The fixing tape has a relatively large adhesive property, which can improve the connection strength, reduce the risk of the cleaning tape and the material strip being disconnected, and improve the cleaning efficiency and the production efficiency.

[0010] In some embodiments, connecting the cleaning tape and the first material strip by the fixing tape and connecting the cleaning tape and the second material strip by the fixing tape includes: connecting the first material strip and the cleaning tape by a first fixing tape; connecting the second material strip and the cleaning tape by a second fixing tape; and spacing the first fixing tape and the second fixing tape along the strip moving direction. In this way, 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 can improve the cleaning effect of the cleaning tape on the roller.

[0011] In some embodiments, the cleaning tape is spaced apart from the first material strip along the strip moving direction, and the cleaning tape is spaced apart from the second material strip along the strip moving direction. In this way, the thickness of the adhesive portion of the material strip can be reduced, the effective cleaning area of the cleaning tape can be increased, and the risk of damaging the material strip can be reduced. In addition, during the movement of the cleaning tape to the first material strip or the second material strip, the cleaning tape is not likely to wrinkle, which can help maintain the flatness of the cleaning tape and improve the cleaning effect of the cleaning tape.

[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, the size of the first gap is d1, and the size of the second gap is d2 along the tape running direction; d1≤5mm, which can reduce the possibility of the first fixed tape sticking to the roller, facilitate reducing the tape running tension, and reduce the risk of tape breakage; and / or d2≤5mm, which can reduce the possibility of the second fixed tape sticking to the roller, facilitate reducing the tape running tension, and reduce 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. In this way, a double connection is formed between the cleaning tape and the first material tape, and / or a double connection is formed between the cleaning tape and the second material tape, which facilitates enhancing the connection strength and reducing the risk of disconnection.

[0014] In some embodiments, the method for connecting the first material tape and the second material tape separated from each other along the tape running direction of the material tape by the tape comprises: moving the beginning end of the cleaning tape wound on the unwinding mechanism to the tape receiving platform; driving the tape sticking mechanism to stick the first fixed tape to the beginning end of the cleaning tape and the first material tape to connect the cleaning tape and the first material tape by the first fixed tape; driving the first material tape to move the cleaning tape away from the second material tape until the cleaning tape on the tape receiving platform reaches a target length; cutting the cleaning tape; moving the tail end of the cleaning tape formed after the cleaning tape is cut to the tape receiving platform; and driving the tape sticking mechanism to stick the second fixed tape to the tail end of the cleaning tape and the second material tape to connect the cleaning tape and the second material tape by the second fixed tape; wherein the adhesion of the cleaning tape is smaller than the adhesion of the first fixed tape and the adhesion of the second fixed tape.

[0015] In some embodiments, before moving the cleaning tape, the method for cleaning the roller further comprises: peeling off the release paper covering the cleaning tape and winding the release paper. In this way, the release paper can be peeled off from the cleaning tape, and the space occupied by the release paper can be reduced, which facilitates cleaning the production environment and facilitates recycling.

[0016] In some embodiments, both sides of the part of the tape between the first material tape and the second material tape have adhesion. In this way, the roller in contact with any side of the tape can be cleaned, the cleaning range is wider, and the cleaning efficiency and cleaning effect are improved.

[0017] According to a second aspect of the present application, the embodiments of the present application provide a material tape processing device, which comprises a roller and a roller cleaning device.

The first suction mechanism is movably arranged along the tape running direction for selectively suctioning or releasing the first tape and the second tape. In this way, the possibility of displacement of the first tape and the second tape can be reduced. When the first tape pressing component releases the first tape, the first tape and / or the second tape can be suctioned and moved by the first suction mechanism, and the damage to the first tape and the second tape can be reduced.

Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0043] Unless otherwise defined, all technical and scientific terms used in the application have the same meanings as those commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used in the description of the application herein is for the purpose of describing the particular embodiments only and is not intended to be limiting of the application; the description and the drawings are to be regarded as illustrative in nature; the word "comprising" and "comprises", and the like, when used in the specification in this application, is used to mean including but not limited to, and when construed together with the word "consisting" or "consisting of" or "having" or "having at least", is used to specify the presence of stated features, integers, steps or components as well as those inherent in the present application and / or additional features, integers, steps, components that do not mutually exclude each other or alternatives thereof.

[0044] Reference to "an embodiment" or "the embodiment" in this application means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the application. The appearances of the phrase "in an embodiment" or "in the embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another.

[0045] In the description of the application, it should be noted that, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connection", "attaching" should be understood in a broad sense, for example, can be fixed connection, can also be detachable connection, or integrally connected; can be directly connected, or indirectly connected through an intermediate medium; can be internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the application can be understood according to the specific circumstances.

[0046] The term "and / or" in the application is only to describe the relationship between the associated objects, which means that there can be three kinds of relationships, for example, A and / or B, which can represent the existence of A alone, the existence of A and B together, and the existence of B alone. In addition, the character " / " in the application generally represents an "or" relationship between the front and rear associated objects.

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

[0048] "Multiple" appearing in the application means two or more (including two).

[0049] In the embodiments of the application, "parallel" not only includes the case of absolute parallel, but also includes the case of approximate parallel which is generally recognized in engineering; at the same time, "perpendicular" not only includes the case of absolute perpendicular, but also includes the case of approximate perpendicular which is generally recognized in engineering.

[0050] In the production process of the battery, the material belt such as the pole piece is usually conveyed by the roller to achieve the support, die cutting, deviation correction and the like of the material belt. After the roller is used for a period of time, the surface of the roller is easy to be contaminated. For example, the dust in the air is adsorbed on the surface of the roller under the action of static electricity; for another example, the impurities on the material belt adhere to the surface of the roller when the material belt passes through the roller; for another example, the roller itself generates fine debris due to the friction of the material belt or other objects. These impurities can be attached to the material belt passing through the roller, and even pierce the material belt, which affects the production yield of the material belt, and the produced battery has a risk of short circuit, which affects the production yield of the battery.

[0051] In order to clean the roller, one feasible way is to use a dust-free paper or a dust-free cloth to dip water or alcohol to wipe the roller manually. This way not only takes time and effort, increases cost, but also has defects such as narrow space between the rollers in the equipment, poor safety, incomplete wiping, and 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 high in cost, large in space occupation, and the cleaning device itself also needs to be replaced, which is large in workload and has safety problems when manually replaced.

[0052] In view of this, the embodiments of the present application provide a technical solution which first connects a first material belt and a second material belt which are 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 then drives the whole formed by the first material belt, the second material belt and the adhesive tape 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, and can adhere at least part of the impurities on the surface of the roller, so as to achieve the purpose of cleaning the roller, which is beneficial to improve the production yield of the material belt. The technical solution does not need to separately configure a cleaning device for each roller, which is convenient for maintenance and reduces cost; and the technical solution realizes the cleaning of the roller along with the running process of the material belt, which can reduce the number of shutdowns, reduce the participation of manual labor, and is beneficial to improve 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 beneficial to reasonably select the length of the adhesive tape, improve the phenomenon that the adhesive tape is easy to break due to too long length, and the first material belt and the second material belt connected on both sides of the adhesive tape can be used as the main structure to bear the running tension, which is beneficial to reduce the tension on the adhesive tape and reduce the possibility of the adhesive tape breaking, and thus is beneficial to improve the production efficiency.

The first suction mechanism 33 can release the first tape 201 or the second tape 202 after breaking the vacuum. For example, the first suction mechanism 33 can comprise a vacuum suction disc.

[0068] The embodiments of the present application fix the first tape 201 and the second tape 202 by the first tape pressing component 31 and the second tape pressing component 32 respectively, which is conducive to reducing the possibility of displacement of the first tape 201 and the second tape 202. When the first tape pressing component 31 releases the first tape 201, the first tape 201 and / or the second tape 202 can be suctioned and moved by the first suction mechanism 33, which can reduce the damage to the first tape 201 and the second tape 202.

[0069] In some embodiments, the adhesive tape 3 comprises a cleaning adhesive tape 301 and a fixing adhesive tape 302.

[0083] The slitting device 50 can include a slitting driving mechanism and a blade, the slitting driving mechanism is configured to drive the blade to move close to or away from the material tape 2, so as to selectively slit the material tape 2. For example, when the material tape 2 needs to be slit, the slitting driving mechanism drives the blade to move close to the material tape 2 and contact the material tape 2; when the material tape 2 does not need to be slit, the slitting driving mechanism drives the blade to move away from the material tape 2 and separate from the material tape 2.

[0084] The over roller cleaning device is located upstream of the slitting device 50, which can clean the over rollers located between the over roller cleaning device and the slitting device 50, and the over rollers located downstream of the slitting device 50, which is beneficial to improve the cleaning efficiency and save the cleaning time.

[0085] In some embodiments, referring to Figure 6 and Figure 7 , the cleaning tape 301 includes a plurality of adhesive portions 3011 having adhesion and at least one non-adhesive portion 3012 not having adhesion, the plurality of adhesive portions 3011 are arranged at intervals along a 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 running direction X.

[0086] The bonding portion 3011 has adhesion and can be bonded to the surface of the material tape 2 and can bond impurities. The non-bonding portion 3012 has no adhesion, and no obvious adhesion force is generated between the non-bonding portion 3012 and the structure in contact with the non-bonding portion 3012.

[0087] The number of the bonding portions 3011 can be the same as the number of the sub-tapes formed by the slitting device 50 slitting the material tape 2, and the number of the non-bonding portions 3012 is the same as the number of the cutting lines of the slitting device 50.

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

[0089] The slitting device 50 can cut the material tape 2 along the region of the material tape 2 corresponding to the non-bonding portion 3012 and avoid the bonding portion 3011 on the material tape 2. The non-bonding portion 3012 has no adhesion, which can reduce the possibility of adhesion of the adhesive substance to the cutting knife and is beneficial to prolong the service life of the slitting device 50. The adjacent two bonding portions 3011 are connected by the non-bonding portion 3012, the width of the non-bonding portion 3012 is constant, the spacing distance between the adjacent two bonding portions 3011 can be kept constant, and the risk that the spacing distance between the adjacent two bonding portions 3011 is large or small and causes the slitting device 50 to cut the bonding portion 3011 is reduced.

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

[0091] The slitting device 50 can cut the material tape 2 along the region of the material tape 2 corresponding to the gap and avoid the bonding portion 3011 on the material tape 2. There is no adhesive substance at the gap, which can reduce the possibility of adhesion of the adhesive substance to the cutting knife and is beneficial to prolong the service life of the slitting device 50. No other structure is arranged between the adjacent two bonding portions 3011, and the adjacent two bonding portions 3011 are independently arranged, which is beneficial to save materials and reduce costs.

[0092] Figure 8 FIG. 1 is a flow diagram of a method for cleaning a roller according to some embodiments of the present application. Referring to FIG. 1, the method for cleaning a roller according to some embodiments of the present application includes the following steps. Figure 8 The method for cleaning a roller according to some embodiments of the present application includes the following steps.

[0093] In step S20, the first material tape 201 and the second material tape 202 separated from each other along the tape running direction X of the material tape are connected by 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.

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

[0095] The first tape 201 and the second tape 202 can be two sections of tape formed by cutting one tape, or two tapes respectively.

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

[0097] After the adhesive tape 3 connects the first tape 201 and the second tape 202, a part of the adhesive tape 3 can be located between the first tape 201 and the second tape 202, and can be exposed outside through the gap between the first tape 201 and the second tape 202, so as to facilitate contacting the roller 10.

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

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

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

[0101] In step S40, one of the first tape 201 and the second tape 202 located upstream can be driven to move along the tape direction X, so as to drag the adhesive tape 3 and the other one of the first tape 201 and the second tape 202 located downstream to move along the tape direction X.

[0102] At least one side of the part of the adhesive tape 3 located between the first tape 201 and the second tape 202 has adhesion, which can adhere impurities such as metal particles, burrs, lint and dust.

[0103] When the adhesive tape 3 passes through the downstream roller 10, the part of the adhesive tape 3 between the first material tape 201 and the second material tape 202 contacts the roller 10, the adhesive tape 3 has a greater adhesion to impurities on the surface of the roller 10 than the attachment between the roller 10 and the impurities, and the adhesive tape 3 can stick at least part of the impurities on the surface of the roller 10, so as to clean the roller 10, thereby improving the production yield of the material tape.

[0104] The embodiment of the present application does not need to separately configure a cleaning device for each roller 10, which is convenient for maintenance and reduces cost. The embodiment of the present application realizes cleaning of the roller 10 during the running process of the material tape, which can reduce the number of shutdowns, reduce manual participation, and improve the production efficiency and production safety of the material tape. More importantly, the adhesive tape 3 is connected between the first material tape 201 and the second material tape 202, which is conducive to reasonably selecting the length of the adhesive tape 3 and improving the phenomenon that the adhesive tape 3 is easily broken due to too long length. In addition, the first material tape 201 and the second material tape 202 connected on both sides of the adhesive tape 3 can be used as the main structure to bear the running tension, which is conducive to reducing the tension on the adhesive tape 3 and reducing the possibility of the adhesive tape 3 being broken, thereby improving the production efficiency.

[0105] Figure 9 is a flowchart of a roller cleaning method provided by another embodiment of the present application. Referring to Figure 9 In some embodiments, before the first material tape 201 and the second material tape 202 separated from each other are connected 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 platform 20 to form the first material tape 201 and the second material tape 202; and

[0107] Step S120, moving at least one of the first material tape 201 and the second material tape 202 to separate the first material tape 201 and the second material tape 202 from each other along the running direction X.

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

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

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

[0111] The tape joint platform 20 can be one of the stations of the tape processing device 1. When the cleaning of the roller 10 is not needed, the tape 2 can pass through the station of the tape joint platform 20 normally. When the cleaning of the roller 10 is needed, the tape 2 can be cut at the station of the tape joint platform 20, and the adhesive tape 3 can be connected at the cut position. This is beneficial to flexibly select the cleaning time of the roller 10, and improve the timeliness and convenience of the cleaning of the roller 10.

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

[0113] Lifting the first tape pressing component 31 on the tape joint platform 20 for fixing the first tape 201;

[0114] Using the first adsorption mechanism 33 movably arranged to adsorb the first tape 201, and drive the first tape 201 to move away from the second tape 202.

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

[0116] Before the cutting of the tape 2, the tape 2 can be pressed by the tape pressing component to reduce the risk of displacement of the tape 2 in the process of cutting the tape 2. Alternatively, the tape 2 can be pressed by the first tape pressing component 31 to form part of the first tape 201.

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

[0118] The embodiments of the present application fix the first tape 201 by the first tape pressing component 31, which is beneficial to reduce the possibility of displacement of the first tape 201. After the first tape pressing component 31 releases the first tape 201, the first tape 201 can be adsorbed and moved by the first adsorption mechanism 33, which can reduce the damage to the first tape 201.

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

[0120] Lifting the second tape pressing component 32 on the tape joint platform 20 for fixing the second tape 202;

[0121] Using the first adsorption mechanism 33 movably arranged to adsorb the second tape 202, and drive the second tape 202 to move away from the first tape 201.

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

[0123] The second tape pressing component 32 can fix the second material tape 202 by pressing, clamping or other suitable manners. Exemplarily, the second tape pressing component 32 can include a tape pressing rod.

[0124] Before cutting the material tape 2, the material tape 2 can be fixed by the tape pressing component to reduce the risk of displacement of the material tape 2 in the process of cutting the material tape 2. Alternatively, the material tape 2 can be fixed by the second tape pressing component 32 for forming the part of the second material tape 202.

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

[0126] The embodiments of the present application fix the second material tape 202 by the second tape pressing component 32, which is beneficial to reduce the possibility of displacement of the second material tape 202. After the second tape pressing component 32 releases the second material tape 202, the first suction mechanism 33 can be used to suck and move the second material tape 202, which can reduce the damage to the second material tape 202.

[0127] In some embodiments, one of the first material tape 201 and the second material tape 202 can be moved by the first suction mechanism 33 first, and then the other one of the first material tape 201 and the second material tape 202 can be moved by the first suction mechanism 33. The position of the first material tape 201 and the second material tape 202 can be adjusted by the movement of the first suction mechanism 33, which is beneficial to simplify the structure.

[0128] Figure 10 is a flowchart of connecting the first material tape and the second material tape separated from each other along the running direction of the material tape by the adhesive tape in the over-roll cleaning method provided by some embodiments of the present application. Referring to Figure 10 In some embodiments, the first material tape 201 and the second material tape 202 separated from each other along the running direction X of the material tape are connected by the adhesive tape 3, which can specifically include:

[0129] In step S201, the cleaning adhesive tape 301 is moved to make at least part of the cleaning adhesive tape 301 located between the first material tape 201 and the second material tape 202; and

[0130] In step S202, the cleaning adhesive tape 301 and the first material tape 201 are connected by the fixing adhesive tape 302, and the cleaning adhesive tape 301 and the second material tape 202 are connected.

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

[0132] The cleaning tape 301 is mainly used for cleaning the over roller 10, and the fixing tape 302 is mainly used for connecting the first tape 201 and the second 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 interval between the first tape 201 and the second tape 202. At this time, the cleaning tape 301 can be moved and carried as a whole, so that at least part of the cleaning tape 301 is located between the first tape 201 and the second tape 202.

[0134] In step S201, the beginning end of the cleaning tape 301 in the winding state can also be moved and carried. After the cleaning tape 301 is unwound to a length matching the interval between the first tape 201 and the second tape 202 by traction, unwinding or other suitable means, the cleaning tape 301 is cut.

[0135] The cleaning tape 301 can be located between the first tape 201 and the second tape 202 as a whole, or only part of the cleaning tape 301 can be located between the first tape 201 and the second tape 202. For example, part of the cleaning tape 301 can overlap the first tape 201, and part of the cleaning tape 301 can overlap the second tape 202.

[0136] The cleaning tape 301 and the first tape 201 can be indirectly connected only by the fixing tape 302, or can be indirectly connected by the fixing tape 302 while being directly connected. The cleaning tape 301 and the second tape 202 can be indirectly connected only by the fixing tape 302, or can be indirectly connected by the fixing tape 302 while being directly connected.

[0137] The fixing tape 302 can have adhesion on one side, and the side with adhesion of the fixing tape 302 is bonded to the cleaning tape 301, the first tape 201 and the second tape 202. The fixing tape 302 has adhesion on one side, which can reduce the contact between the adhesive material of the fixing tape 302 and the over roller 10, and reduce the adverse effects of the fixing tape 302 on the over roller 10.

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

[0139] The impurities on the over roller 10 are usually attached to the roller surface under the action of static electricity, gravity or other forces, and can be detached from the over roller 10 only under the action of a small external force. Therefore, the adhesion of the cleaning tape 301 used to contact the over roller 10 is relatively small, which can not only stick and remove at least part of the impurities on the surface of the over roller 10 to achieve the purpose of cleaning the over roller 10, but also reduce the risk of the cleaning tape 301 being adhered to the over roller 10 and not being easily separated from the over roller 10, thereby facilitating the more smooth running of the entire belt formed by the first material belt 201, the second material belt 202 and the belt 3. Moreover, the cleaning tape 301 has relatively small adhesion, and the adhesive substance of the cleaning tape 301 is not likely to stay on the surface of the over roller 10, thereby reducing the risk of the adhesive substance again contaminating the material belt 2.

[0140] The adhesion of the fixing tape 302 is relatively large, which is conducive to improving the connection strength between the cleaning tape 301 and the first material belt 201, improving the connection strength between the cleaning tape 301 and the second material belt 202, reducing the risk of the cleaning tape 301 and the first material belt 201 being disconnected, reducing the risk of the cleaning tape 301 and the second material belt 202 being disconnected, and facilitating the improvement of cleaning efficiency and production efficiency.

[0141] In some embodiments, the connection of the cleaning tape 301 and the first material belt 201 by the fixing tape 302 and the connection of the cleaning tape 301 and the second material belt 202 by the fixing tape 302 include:

[0142] adhering the first material belt 201 and the cleaning tape 301 by the first fixing tape 3021; and

[0143] adhering the second material belt 202 and the cleaning tape 301 by the second fixing tape 3022.

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

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

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

[0147] The first fixing tape 3021 and the second fixing tape 3022 are located on the same side of the cleaning tape 301, and can also be located on two sides of the cleaning tape 301 respectively.

[0148] In step S202, the first fixing tape 3021 can be attached along the width direction of the first material tape 201, and the second fixing tape 3022 can 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 exceed the cleaning tape 301. Along the width direction of the second material tape 202, both ends of the second fixing tape 3022 do not exceed the cleaning tape 301.

[0150] The size of the first fixing tape 3021 along the running direction X is the same as the size of the second fixing tape 3022 along the running direction X, and the same tape attaching mechanism can be used to attach the first fixing tape 3021 and the second fixing tape 3022.

[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, increase the area of the cleaning tape 301 exposed to the outside, and be beneficial to improving the cleaning effect of the cleaning tape 301 on the roller 10.

[0152] In some embodiments, along the running direction X, the cleaning tape 301 and the first material tape 201 are arranged at intervals, and the cleaning tape 301 and the second material tape 202 are arranged at intervals. The cleaning tape 301 is located between the first material tape 201 and the second material 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 portion of the first material tape 201 adjacent to the cleaning tape 301, and cover the end portion of the cleaning tape 301 adjacent to the first material tape 201. 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 and the cleaning tape 301 partially overlap, and the second fixing tape 3022 and the second material tape 202 partially overlap. The second fixing tape 3022 can cover the end portion of the cleaning tape 301 adjacent to the second material tape 202, and cover the end portion of the second material tape 202 adjacent to the cleaning tape 301. 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 the part of the material tape after the adhesive is too thick, a step will be formed between the part and the adjacent other part, which causes the part of the cleaning tape 301 close to the step to be unable to contact the over roller 10, the effective cleaning area of the cleaning tape 301 is reduced, and the step can also affect the flatness of the material tape and even damage the material tape.

[0156] Therefore, in the embodiments of the present application, the cleaning tape 301 is arranged to be spaced apart from the first material tape 201 and spaced apart from the second material tape 202, and the phenomenon that the cleaning tape 301, the first material tape 201 and the first fixed tape 3021 are overlapped and the phenomenon that the cleaning tape 301, the second material tape 202 and the second fixed tape 3022 are overlapped do not occur, which is beneficial to reduce the thickness of the adhesive part of the material tape, increase the effective cleaning area of the cleaning tape 301 and reduce the risk of damaging the material tape. In addition, in the process of moving the cleaning tape 301 to the first material tape 201 or the second material tape 202, the cleaning tape 301 is not prone to the phenomenon of wrinkling, which is beneficial to keep the cleaning tape 301 flat and improve the 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. In the 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 fixed tape 3021 is used to connect the cleaning tape 301 and the first material tape 201, and the adhesion of the first fixed tape 3021 is usually large. The first fixed tape 3021 covers the first gap 401, and the part of the first fixed tape 3021 corresponding to the first gap 401 will be exposed and will contact the over roller 10. If the size of d1 is too large, the area of the first fixed tape 3021 contacting the over roller 10 is too large, which is easy to stick to the over roller 10 and is not easy to separate from the over roller 10.

[0159] Therefore, in the embodiments of the present application, d1 is set to be less than or equal to 5mm, which can reduce the possibility of the first fixed tape 3021 sticking to the over roller 10, is beneficial to reduce the running tension and reduce the risk of breaking the tape.

[0160] Similarly, if the size of d2 is too large, the area of the second fixed tape 3022 contacting the over roller 10 is too large, which is easy to stick to the over roller 10 and is not easy to separate from the over roller 10.

[0161] Therefore, in the embodiments of the present application, d2 is set to be less than or equal to 5mm, which can reduce the possibility of the second fixed tape 3022 sticking to the over roller 10, is beneficial to reduce the running tension and reduce the risk of breaking the tape.

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

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

[0164] The cleaning tape 301 can be adhered to the second tape 202, and there is an overlapping portion 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 adhered to the same side surface of the cleaning tape 301 and the second tape 202.

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

[0166] The cleaning tape 301 is directly adhered to the first tape 201, and there is an adhering action between the cleaning tape 301 and the first tape 201. The first fixing tape 3021 is used to reinforce the connection between the cleaning tape 301 and the first tape 201, and a double connection is formed between the cleaning tape 301 and the first tape 201, which is beneficial to enhance the connection strength and reduce the risk of disconnection.

[0167] The cleaning tape 301 is directly adhered to the second tape 202, and there is an adhering action between the cleaning tape 301 and the second tape 202. The second fixing tape 3022 is used to reinforce the connection between the cleaning tape 301 and the second tape 202, and a double connection is formed between the cleaning tape 301 and the second tape 202, which is beneficial to enhance the connection strength and reduce the risk of disconnection.

[0168] Figure 11 is a flowchart of the process of connecting the first tape and the second tape separated from each other along the running direction of the tape by the tape in the over-roll cleaning method provided by some other embodiments of the present application. Referring to Figure 11 In some embodiments, the first tape 201 and the second tape 202 separated from each other along the running direction X of the tape are connected by the tape 3, so that a part of the tape 3 is located between the first tape 201 and the second tape 202, including:

[0169] In step S211, the starting end of the cleaning tape 301 wound on the unwinding mechanism 34 is moved to the tape receiving platform 20 (refer to Figure 3 );

[0171] Step S213, the first material tape 201 drives the cleaning adhesive tape 301 to move away from the second material tape 202 until the cleaning adhesive tape 301 on the tape receiving platform 20 reaches the target length.

[0172] Step S214, the cleaning adhesive tape 301 is cut off.

[0173] Step S215, the tail end of the cleaning adhesive tape 301 after being cut off is moved to the tape receiving platform 20; and

[0174] Step S216, the second fixed adhesive tape 3022 is attached to the tail end of the cleaning adhesive tape 301 and the second material tape 202 by the adhesive tape attaching mechanism 35, so as to connect the cleaning adhesive tape 301 and the second material tape 202 through the second fixed adhesive tape 3022 (see Figure 5 )。

[0175] The viscosity of the cleaning adhesive tape 301 is less than the viscosity of the first fixed adhesive tape 3021 and the viscosity of the second fixed adhesive tape 3022.

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

[0177] The length of the cleaning adhesive tape 301 on the tape receiving platform 20 means the length of the cleaning adhesive tape 301 on the tape receiving platform 20 for connecting the first material tape 201 and the second material tape 202.

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

[0179] The beginning end of the cleaning adhesive tape 301 is the end of the cleaning adhesive tape 301 in the winding state on the outside.

[0180] In step S211, the second adsorption mechanism 36 which can be moved is used to adsorb the cleaning adhesive tape 301 and drive the beginning end of the cleaning adhesive tape 301 to move to the tape receiving platform 20.

[0181] The first adsorption mechanism 33 and the second adsorption mechanism 36 can be respectively located on the upper and lower sides of the tape receiving platform 20.

[0182] After step S211 and before step S212, the over roller cleaning method of the embodiments of the present application can further include: using the first movable suction mechanism 33 to suck the cleaning tape 301; and controlling the second suction mechanism 36 to release the cleaning tape 301 and move the receiving platform 20 out of the way to reduce the possibility of interference between the second suction mechanism 36 and the tape sticking 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 move the tail end of the cleaning tape 301 to the receiving platform 20. Then, 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 the receiving platform 20 out of the way to reduce the possibility of interference between the second suction mechanism 36 and the tape sticking mechanism 25.

[0187] In some embodiments, the adhesive tape 3 has adhesiveness on both sides of the part between the first material tape 201 and the second material tape 202.

[0188] When the adhesive tape 3 moves, it will not only keep one side in contact with the over roller 10. For example, when the whole reversing is formed by the first material tape 201, the second material tape 202 and the adhesive tape 3, the side of the adhesive tape 3 in contact with different over rollers 10 is also different.

[0189] The embodiments of the present application set the part of the adhesive tape 3 between the first material tape 201 and the second material tape 202 to have adhesiveness on both sides, so that the over roller 10 in contact with any side of the adhesive tape 3 can be cleaned, the cleaning range is wider, and the cleaning efficiency and effect are improved.
