Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of glue coating, and more particularly to a glue coating self-cleaning device and glue coating equipment. BACKGROUND

[0002] In the related art, a glue coating device has a glue coating roller. The roller surface of the glue coating roller is coated with glue. When the roller surface of the glue coating roller contacts a strip, the glue on the roller surface is transferred to the strip to form a glue coated strip. During use, the glue coating roller is exposed to air for a long time, and the roller surface of the glue coating roller is coated with glue. Therefore, dust in the air is easily attached to the glue coating roller. Even if the glue coating device is operated in a dust-free workshop, there may be a small amount of debris on the surface of the strip. After the glue coating roller is operated for a long time, the debris on the surface of the strip is enriched on the glue coating roller. Eventually, the contaminants are attached to the strip along with the glue transferred by the glue coating roller. However, many strips are sensitive to contaminants. For example, amorphous strips used to manufacture stator cores or rotor back irons of motors. After the strips are coated with glue, the strips are finally manufactured into stator cores or rotor back irons. The mixing of contaminants reduces the lamination coefficient of the cores or back irons, thereby affecting the performance of the motor in which the cores or back irons are installed. In order to meet the needs of motors for higher performance, a glue coating device with better glue coating effect is needed. SUMMARY

[0039] In order to make the above objectives, features and advantages of the present application more apparent, specific embodiments of the present application are described in detail below with reference to the accompanying drawings. In the following description, a large number of specific details are set forth in order to facilitate a full understanding of the present application. However, the present application can be implemented in many different ways other than those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited to the specific embodiments disclosed below.

[0040] In the description of the present application, it should be understood that the terms "center", "length", "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0041] In addition, the terms "first", "second" are only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include at least one of the features. In the description of the present application, the meaning of "a plurality of" is at least two, for example, two, three, etc., unless otherwise specifically limited.

[0042] In the present application, unless specifically defined otherwise, the terms "mount", "connected", "connecting", and the like, should be interpreted broadly, for example, can be fixed connection, can also be detachable connection, or integral; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, can be the internal communication of two elements or the interaction relationship between two elements, unless specifically defined otherwise. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0043] In the present application, unless specifically defined otherwise, the first feature is "on" or "under" the second feature can be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature "above", "over" and "on" the second feature can be that the first feature is directly above or obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "under" and "under" the second feature can be that the first feature is directly below or obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

[0044] The strip can be an amorphous strip made of amorphous alloy, such strip has very important application in the field of electric machines, because amorphous alloy can have higher electrical resistance, lower coercivity and greater relative magnetic permeability. When amorphous alloy is made into the core structure of the back iron or stator of the rotor of the electric machine, a larger magnetic field can be generated in the electric machine, so that a larger torque can be output, while smaller eddy current loss and hysteresis loss (i.e. iron loss) can be achieved. However, during the manufacturing process of amorphous alloy, rapid cooling or techniques for inhibiting the generation of crystal nucleus can be used to make the amorphous alloy brittle and thin, which makes the strip made of amorphous alloy also very thin, and the thickness of the commonly used strip can be 25 μm. The strip needs to be cut, and conventional cutting means such as laser cutting can cause the temperature of the cut material to rise, which is not conducive to amorphous alloy, because after the temperature of the amorphous alloy rises and then cools down, there is a risk of recrystallization, which can cause the performance of the amorphous alloy to decrease. Therefore, a more preferred cutting method is to use stamping cutting. However, stamping is technically more difficult for thin strips, so the strip made of amorphous alloy needs to be overlapped in multiple layers first, and then stamped, so that the thickness of the overlapped strip is larger, which is more convenient for stamping.

[0045] In the process of overlapping the strips, glue needs to be applied between the strips so as to bond the strips together. However, since the strips will eventually be overlapped to form a core or back iron of an electric machine, the amount of glue needs to be as little as possible so that the proportion of glue in the total weight of the core or back iron formed by the strips is smaller and the proportion of the strips is larger, i.e. a higher lamination coefficient can be obtained. However, if contaminants, i.e. some dust or debris on the strips, are mixed with the glue on the surface of the glue applying roller, the contaminants will be loaded between two strips with the glue, causing the flatness of the strips to decrease, and the glue will gather at the position of the debris, causing more glue to be clamped in the strips and reducing the lamination coefficient.

[0046] Reference is made to Figure 1 The embodiment of the present application provides a glue applying self-cleaning device 110, which comprises a glue applying roller 111, a glue supplying assembly 112 and a cleaning assembly 113. The glue applying roller 111 is used for applying glue to the strips 20 to form glued strips 30. The glue supplying assembly 112 is used for supplying glue to the surface of the glue applying roller 111. The cleaning assembly 113 is used for supplying cleaning medium to the glue applying roller 111 to clean the glue applying roller 111.

[0047] The glue applying roller 111 is a roller used for applying glue to the strips 20. Specifically, the glue applying roller 111 can be a smooth roller. After the glue applying roller 111 is coated with glue, the glue applying roller 111 is contacted with the strips 20, i.e. the glue on the glue applying roller 111 is transferred to the strips 20, so that the glue applying to the strips 20 is completed. After the strips 20 are glued, the glued strips 30 are formed.

[0048] The glue supplying assembly 112 is an assembly used for supplying glue to the surface of the glue applying roller 111. Specifically, in the embodiment shown in the drawings, the glue supplying assembly 112 comprises a glue outlet 1121 and a scraper 1122. The glue outlet 1121 is a device for supplying glue, and the scraper 1122 is a device for scraping the glue attached to the surface of the glue applying roller 111 to a preset thickness. In other embodiments, the glue supplying assembly can adopt one of a slot die, an anilox die, a comma blade or a screen printing. Figure 1 The cleaning assembly 113 is an assembly for supplying cleaning medium to the glue applying roller 111. Specifically, the cleaning assembly 113 can comprise a spraying device and / or a coating device. The spraying device can spray cleaning medium in a gaseous, solid, liquid, solid-liquid mixed or gas-liquid mixed state, and the coating device can supply cleaning medium in a liquid state. The cleaning medium is a medium with cleaning ability and can carry away the contaminants on the glue applying roller 111.

[0049]

[0050] ​The cleaning assembly 113 can provide cleaning medium to the rubber coating roller 111, so that the contaminants on the rubber coating roller 111 can be cleaned in time, avoiding the contaminants entering between the strips 20 with the rubber material, improving the rubber coating effect, and thus improving the lamination coefficient of the back iron or core made of the strips 20, meeting the needs of higher performance of the motor. In addition, it can be understood that the embodiments of the present application can also be applied to strips 20 made of ordinary materials, and the rubber coating effect can also be improved.

[0051] Please refer to Figure 1 The rubber coating roller 111 can include a first rubber coating roller 1111 and a second rubber coating roller 1112, and the first rubber coating roller 1111 and the second rubber coating roller 1112 are oppositely arranged, the first rubber coating roller 1111 is used for coating rubber on the strips 20, and the second rubber coating roller 1112 assists the first rubber coating roller 1111 to coat rubber on the strips 20. Please refer to Figure 1 and Figure 2 The second unwinding device 117 can be used to provide the strips 20 to the rubber coating self-cleaning device 110, and the strips 20 are unwound through the second unwinding device 117, guided by the first guide roller 118, and then enter the rubber coating self-cleaning device 110. In other embodiments, a conveying device such as a conveyor belt can also be used to provide the strips to the rubber coating self-cleaning device.

[0052] Please refer to Figure 1 In some embodiments, the cleaning assembly 113 includes a cleaning agent providing device 1131 for providing cleaning agent to the rubber coating roller 111. The cleaning agent providing device is a device for providing cleaning medium in liquid, liquid-gas mixed or solid-liquid mixed state. The cleaning agent providing device can include a discharge nozzle, which can provide cleaning agent in a slow flow or jetting manner, so that the cleaning agent flows or sprays onto the roller surface of the rubber coating roller 111. The cleaning agent can be non-dissolving, so that the contaminants on the rubber coating roller 111 can be washed away by flushing. The cleaning agent can also be dissolving, so that the contaminants on the rubber coating roller 111 can be dissolved with the rubber material, and the deeper contaminants can leave the surface of the rubber coating roller 111 together with the rubber material. It can be seen that the cleaning agent providing device 1131 can clean the contaminants on the rubber coating roller 111 by flushing or dissolving, improving the cleaning effect of the rubber coating roller 111.

[0053] Please refer to Figure 1 In some embodiments, the cleaning assembly 113 includes a gas providing device 1132 for spraying cleaning gas to the rubber coating roller 111. The cleaning gas can be air or inert gas, such as argon. The cleaning gas can blow off the contaminants on the rubber coating roller 111, thereby improving the cleaning effect of the rubber coating roller 111. Please refer to Figure 1The gas providing member 1132 can also work together with the cleaning agent providing member 1131. In this way, the gas providing member 1132 can also be used to blow the cleaning agent provided by the cleaning agent providing member 1131 off the glue applying roller 111, which can make the cleaning process of the glue applying roller 111 faster, thereby improving the working efficiency of the glue applying device 100.

[0054] Please refer to Figure 1 In some embodiments, the cleaning assembly 113 further comprises a collecting member 114, which is provided with a collecting groove 1141 facing the glue applying roller 111. In the direction of gravity, the collecting member 114 is arranged below the glue applying roller 111, so that the cleaning agent on the glue applying roller 111 can flow into the collecting groove 1141 in the direction of gravity, avoiding the cleaning agent from scattering to other parts of the glue applying device 100, so that the cleaning agent is less likely to dissolve the glue structure or paint water that may exist in the glue applying device 100 itself, thereby improving the service life of the glue applying device 100. In addition, the capacity of the collecting groove 1141 can be set to be sufficient to accommodate the cleaning agent used for multiple cleaning processes, so that the cleaning agent in the collecting groove 1141 can be cleaned after the cleaning assembly 113 completes multiple cleaning processes, thereby improving the convenience of using the glue applying self-cleaning device 110.

[0055] In some embodiments, the glue applying roller is a concave roller. The surface of the concave roller is provided with concave marks that facilitate the adhesion of the glue, so that the glue applying roller can apply glue to the strip.

[0056] Please refer to Figure 1 In some embodiments, the glue providing assembly 112 comprises a glue discharging member 1121 and a scraper 1122. The glue discharging member 1121 is used to provide glue to the glue applying roller 111. The scraper 1122 cooperates with the surface of the glue applying roller 111 to scrape the glue on the surface of the glue applying roller 111 to a predetermined thickness. This makes the control of the glue applying speed and the control of the glue applying thickness of the glue applying self-cleaning device 110 can be carried out separately: when it is necessary to increase (decrease) the glue applying speed, the transmission speed of the strip 20 can be increased (decreased) at the same time as the rotation speed of the glue applying roller 111 and the glue discharging speed of the glue discharging member 1121 are increased (decreased); when it is necessary to reduce (increase) the glue applying thickness, it is only necessary to make the scraper 1122 closer (farther) to the glue applying roller 111. It can be seen that the adjustment of the glue applying speed and the glue applying thickness can not interfere with each other, thereby improving the applicability of the glue applying self-cleaning device 110.

[0057] Please refer to Figure 1In some embodiments, the glue applying self-cleaning device 110 comprises a thickness sensor 115. The thickness sensor 115 is arranged downstream of the glue roller 111 in the conveying direction of the tape 20. In this way, the thickness sensor 115 can be used to detect the thickness of the glue on the glued tape 30. This is advantageous for the glue applying self-cleaning device 110 to control the glue thickness. When the thickness sensor 115 detects that the glue layer is too thick, the doctor blade 1122 can be controlled to be closer to the glue roller 111 to make the glue layer thinner, and vice versa. Therefore, the arrangement of the thickness sensor 115 can improve the automation level of the glue applying self-cleaning device 110.

[0058] The glue applying device 100 of the embodiments of the present application comprises the glue applying self-cleaning device 110 of any of the above embodiments.

[0059] Reference is made to Figure 2In some embodiments, the glue applying device 100 comprises a blowing device 120. The blowing device 120 is arranged downstream of the glue roller 111 in the conveying direction of the tape 20, so that after the tape 20 is glued by the glue roller 111 to form the glued tape 30, the blowing device 120 can blow air to the glue on the glued tape 30 to accelerate the drying speed of the glue, so that the glue can enter the state that can be pasted faster, and thus the tape 20 can enter the overlapping process faster to form the sandwiched tape 40. It can be seen that the arrangement of the blowing device 120 can shorten the length of the glue applying device 100 and improve the glue applying efficiency. The blowing device 120 has a symmetry axis parallel to the surface normal of the tape 20, and the air outlet direction of the blowing device 120 is rotationally symmetric relative to the symmetry axis, and the minimum rotation angle of the air outlet direction relative to the symmetry axis is less than or equal to 180°. It should be noted that the mechanical structure of the blowing device 120 itself is not necessarily symmetric around the symmetry axis, but only the air outlet direction of the blowing device 120 is rotationally symmetric relative to the symmetry axis. For example, the blowing device can comprise a horn-shaped air outlet cylinder, and the axis of the air outlet cylinder is the symmetry axis described above. The air outlet cylinder blows air to the glued tape in the shape of a cone, and a flow velocity field is formed in the cone. The flow velocity direction in the flow velocity field is the air outlet direction, and the flow velocity field overlaps itself at any angle relative to the axis of the air outlet cylinder. In this embodiment, the minimum rotation angle of the air outlet direction of the blowing device relative to the symmetry axis is 0°. When the air blown by the blowing device is transmitted to the glue on the glued tape, it will propagate along the plane direction of the glue after impacting the glue. In the propagation process, the air will have relative friction with the glue. The friction will have a certain pushing force on the tape. When the air outlet direction is rotationally symmetric relative to the symmetry axis, and the minimum rotation angle of the air outlet direction relative to the symmetry axis is less than or equal to 180°, the distribution of the pushing force on the tape, i.e., the force field of the pushing force, also satisfies the symmetry described above, and the resultant force of the pushing force is equal to zero. Therefore, the tape will not wrinkle due to the pushing force (if the resultant force of the pushing force is not zero, the tape position subjected to the air will have a pushing force along the surface of the tape relative to the tape position not subjected to the air, which will cause the tape position subjected to the air to stack on the tape position not subjected to the air. However, the tape will not stack in the conveying process due to the tension on the surface of the tape, but may wrinkle), so that the tape can maintain a balanced state without deviation, shaking or even wrinkling, and the stacking effect of the tape can be improved.

[0060] Please refer to Figure 2In some embodiments, the air blowing device 120 comprises a first air outlet pipe 121, the axis of the first air outlet pipe 121 extends along the normal direction of the surface of the strip 20. In this embodiment, the axis of the first air outlet pipe 121 is the symmetry axis mentioned above, and the flow velocity field of the air flow sent by the first air outlet pipe 121 is obviously relative to the minimum rotation angle of the symmetry axis, which is equal to 0°. In this embodiment, the air blowing device 120 is simple in structure, and the production cost of the air blowing device 120 can be reduced under the premise of keeping the strip 20 in a balanced state.

[0061] Please refer to Figure 2 In some embodiments, the air blowing device 120 further comprises a second air outlet pipe 122, the axis of the second air outlet pipe 122 is at a first preset angle with the axis of the first air outlet pipe 121. The first preset angle is greater than 0° and less than 90°. There are at least two second air outlet pipes 122, and the second air outlet pipes 122 are equally spaced in the circumferential direction of the first air outlet pipe 121. In this embodiment, the axis of the first air outlet pipe 121 also corresponds to the symmetry axis mentioned above. The minimum rotation angle of the air outlet direction relative to the symmetry axis is equal to 360° divided by the number of the second air outlet pipes 122, for example, when the second air outlet pipe 122 is provided with two, the minimum rotation angle is equal to 180°; when the second air outlet pipe 122 is provided with three, the minimum rotation angle is equal to 120°. The air outlet direction rotates a certain angle along the symmetry axis, which is equal to itself, and the minimum angle of this angle is the minimum rotation angle. It can be seen that the above rule is formed due to the equal spacing of the second air outlet pipe 122 in the circumferential direction of the first air outlet pipe 121. The arrangement of the second air outlet pipe 122 can assist the air outlet of the first air outlet pipe 121, increase the air volume of the air blowing device 120, and thus improve the air drying speed of the rubberized strip 30. In addition, the first preset angle can be near 45°, for example, it can be 50°, 49°, 48°, 47°, 46°, 45°, 44°, 43°, 42°, 41°, 40°, or in the range of greater than or equal to 40° and less than or equal to 50°. When the first preset angle is less than or equal to 50°, the air sent by the second air outlet pipe 122 can be transported to the rubberized strip 30 more quickly, avoiding the flow rate drop caused by long-distance transportation, and ensuring the air drying speed. When the first preset angle is greater than or equal to 40°, the air sent by the second air outlet pipe 122 can cover a larger area on the rubberized strip 30, and the air drying speed can be improved.

[0062] Please refer to Figure 2 In some embodiments, the air blowing device 120 is arranged on the side of the rubberized strip 30 where the adhesive is coated. The projection of the air blowing device 120 on the surface of the strip 20 along the normal direction of the surface of the strip 20 is within the range of the rubberized strip 30. In this way, the air flow provided by the air blowing device 120 will not flow to the side of the strip 20 which is not coated with adhesive (for example Figure 2The air flow provided by the blowing device 120 is usually large in flow rate, and if the strip 20 processed by the glue applying device 100 is made of amorphous alloy, if there is air flow on both sides of the strip 20, the air flow on both sides can not be balanced, causing the strip 20 to wrinkle under the action of the air flow. Therefore, in this embodiment, only one side of the strip 20 is subjected to the wind, and only one side of the strip 20 is subjected to the thrust of the wind, so that the strip 20 can be prevented from wrinkling. In addition, in this embodiment, the blowing device 120 is not arranged on the side of the glue applying strip 30 which is not applied with glue. However, if the strip is not made of amorphous alloy, the blowing device can also be arranged on the side of the strip which is not applied with glue to heat the strip and improve the drying speed.

[0063] Please refer to Figure 2 In some embodiments, the glue applying device 100 further comprises a drying device 130, which is arranged downstream of the glue applying self-cleaning device 110 in the conveying direction of the strip 20. The drying device 130 comprises a drying box 131 and a heating element 132. The blowing device 120 is arranged in the drying box 131, and the glue applying strip 30 passes through the drying box 131, so that the drying of the strip 20 can pass through a relatively stable environment and is not easily disturbed by external cold air flow, thereby improving the drying speed. The heating element 132 is arranged in the drying box 131. The heating element 132 can be arranged on the inner surface of the drying box 131, or can be arranged on the outer surface of the drying box 131, or can be embedded in the wall of the drying box 131. The heating element 132 can be a heating wire, a semiconductor heating sheet or a heat conducting rod (which requires an external heat source to heat), etc. In this way, the temperature in the drying box 131 can be raised or lowered by controlling the heating power of the heating element 132. The arrangement of the heating element 132 further improves the drying speed of the glue of the strip 20, and also avoids external interference and the influence of atmospheric temperature on the drying speed, thereby improving the yield of the glue applying device 100.

[0064] Please refer to Figure 2In some embodiments, the glue coating apparatus 100 comprises at least two glue coating self-cleaning devices 110. The drying box 131 comprises a box body 1311 and a partition 1312, the partition 1312 divides the space in the box body 1311 into at least two drying cavities 1313, and each glue coating self-cleaning device 110 forms a glue coating strip 30 which passes through each drying cavity 1313, i.e. one glue coating strip 30 formed by one glue coating self-cleaning device 110 passes through one drying cavity 1313. The drying cavities 1313 are provided with blowing devices 120 on the side opposite to the side on which the glue is coated on the glue coating strip 30, so that the partition 1312 can prevent the hot air provided by the blowing devices 120 in other drying cavities 1313 from flowing to the side of the glue coating strip 30 on which no glue is coated, and can protect the amorphous alloy manufactured strip 20. The box body 1311 and the partition 1312 are both provided with heating elements 132, so that the heating of the drying cavities 1313 is more uniform.

[0065] Please refer to Figure 2 In some embodiments, the glue coating apparatus 100 comprises at least two glue coating self-cleaning devices 110. The glue coating apparatus 100 further comprises a strip stacking device 140, which is located downstream of the drying device 130 of the glue coating self-cleaning device 110 in the transmission direction of the strip 20, i.e. in the embodiments in which no drying device is provided, the strip stacking device is only provided downstream of the glue coating self-cleaning device; please refer to Figure 2 In the embodiments in which the drying device 130 is provided, the strip stacking device 140 is further provided downstream of the drying device 130. The strip stacking device 140 is used to stack the strips 20 output by each glue coating self-cleaning device 110 to form a sandwiched strip 40. In this way, the glue coating apparatus 100 can be integrated with glue coating and stacking, and the processing efficiency of the strip 20 is improved. In Figure 2 In the embodiments shown in the drawings, the strip stacking device 140 can comprise a plurality of pairs of hot pressing rollers 1431, which are used to stack the strips 20 one by one to improve the strength of the bonding after stacking. However, in other embodiments, the hot pressing rollers can also be provided in only one pair, and the pair of hot pressing rollers is used to stack all the strips at the same time to improve the production efficiency. In other embodiments, the strip stacking device can comprise a flat plate pressing head, which is used to press the plurality of glue coating strips into a sandwiched strip in sections.

[0066] Please refer to Figure 2In some embodiments, the rubber coating apparatus 100 further comprises at least two first deviation adjustment members 116, which are arranged one-to-one with the rubber coating self-cleaning devices 110. The first deviation adjustment members 116 are arranged between the rubber coating self-cleaning devices 110 and the lamination device 140, and are used to adjust the position of the rubber coating tapes 30 in the width direction of the rubber coating tapes 30. This facilitates the alignment of the rubber coating tapes 30 in the width direction of the rubber coating tapes 30, and avoids the edges of individual rubber coating tapes 30 in the width direction exceeding other rubber coating tapes 30 during the lamination of the rubber coating tapes 30 by the lamination device 140, so that the edges of the laminated rubber coating tapes 40 in the width direction formed by the lamination device 140 are not usable, thereby increasing the usable area of the laminated rubber coating tapes 40.

[0067] Please refer to Figure 2 and Figure 3 In some embodiments, the rubber coating apparatus 100 further comprises a winding device 150, which is arranged downstream of the lamination device 140 in the conveying direction of the laminated rubber coating tapes 40, and is used to wind the laminated rubber coating tapes 40 into a tape roll. This facilitates the packaging and / or transportation of the laminated rubber coating tapes 40, and facilitates the transportation of the laminated rubber coating tapes 40 to the next device. Please refer to Figure 2 During the transportation of the laminated rubber coating tapes 40 from the lamination device 140 to the winding device 150, at least one second guide roller 155 can be arranged to transport the laminated rubber coating tapes 40 to the lamination device 140 in a proper direction, thereby improving the flexibility of the arrangement of the rubber coating apparatus 100. In other embodiments, the second guide roller can also be omitted, and the discharge direction of the lamination device 140 can be aligned with the feeding direction of the winding device 150, without the need for intermediate guide devices, thereby reducing the manufacturing cost of the rubber coating apparatus.

[0068] Please refer to Figure 2 and Figure 3 In some embodiments, the winding device 150 comprises a second deviation adjustment member 151 and a winding member 152. The second deviation adjustment member 151 is arranged downstream of the lamination device 140 and upstream of the winding member 152 in the conveying direction of the laminated rubber coating tapes 40. The second deviation adjustment member 151 is used to adjust the position of the laminated rubber coating tapes 40 in the width direction of the laminated rubber coating tapes 40, and the winding member 152 is used to wind the laminated rubber coating tapes 40 into a tape roll. Thus, the position of the laminated rubber coating tapes 40 in the width direction has been adjusted by the second deviation adjustment member 151 before the winding member 152 winds the laminated rubber coating tapes 40, which can improve the uniformity of the tape roll in the axial direction, avoid part of the laminated rubber coating tapes 40 protruding from the tape roll in the axial direction of the tape roll, and facilitate the packaging and / or transportation of the tape roll.

[0069] Please refer to Figure 2 and Figure 3In some embodiments, the winding device 150 further comprises a tension detector 153. The tension detector 153 is disposed between the second deviation adjusting member 151 and the winding member. The tension detector 153 is used to detect the tension on the adhesive tape 40, and when the tension is too large, the winding member can reduce the winding torque; when the tension is too small, the winding member can increase the winding torque. In this way, it is avoided that the tape roll is torn due to too large tension, and it is also avoided that the tape roll is loose and the volume is increased due to too small tension. Therefore, the setting of the tension detector 153 improves the yield and the ease of use of the winding device 150.

[0070] Please refer to Figure 3 In some embodiments, the winding device 150 further comprises a welding member 154, which is used to weld the tape roll. In this way, when the winding of the tape roll is completed, the welding member 154 can weld the radially outermost layer of the tape roll with the radially second layer from the outside to the inside, so as to avoid the unwinding of the tape roll, and facilitate the packaging and / or transportation of the tape roll. The welding member 154 can be an electric welder that can rotate and / or move, so as to facilitate the welding of the tape roll.

[0071] Please refer to Figure 2 In some embodiments, the tape stacking device 140 comprises a first unwinding member 141, a third deviation adjusting member 142, and a tape stacker 143. The first unwinding member 141 is used to provide the tape 20 to the tape stacker 143. The tape stacker 143 is used to stack the adhesive tape 40 output by each adhesive self-cleaning device 110 and the tape 20 provided by the first unwinding member 141, so as to form the adhesive tape 40. This can make the outermost layer of the adhesive tape 40 in the thickness direction not have adhesive, and only have adhesive between the tapes 20, so as to facilitate the winding and / or packaging and / or transportation of the adhesive tape 40. The third deviation adjusting member 142 is disposed between the tape stacker 143 and the first unwinding member 141, and is used to adjust the position of the tape 20 in the width direction of the tape 20. In this way, the tape 20 provided by the first unwinding member 141 and the adhesive tape 40 provided by the adhesive self-cleaning device 110 are better aligned in the width direction, so as to improve the usable area of the adhesive tape 40. In Figure 2 In the illustrated embodiments, the tape stacker 143 can comprise a plurality of pairs of hot-pressing rollers 1431, which are used to overlap the plurality of tapes 20 one by one, so as to improve the strength of the adhesion after overlapping. However, in other embodiments, the hot-pressing rollers can also be provided in only one pair, and the one pair of hot-pressing rollers is used to overlap all the tapes at the same time, so as to improve the production efficiency. In other embodiments, the tape stacker can comprise a flat plate pressing head, which is used to press the plurality of adhesive tapes into the adhesive tape in sections.
