Fig. 1 shows a schematic structural diagram of a tape structure 1 at a viewing angle in an embodiment of the related art; fig. 2 is a schematic diagram illustrating a structure of the adhesive tape structure 1 at another view angle in an embodiment of the related art; fig. 3 is a schematic structural view showing a stacked adhesive tape structure 1 in an embodiment of the related art; fig. 4 is a schematic view illustrating a tape taking structure 1 according to an embodiment of the related art; for convenience of explanation, only matters related to the related art embodiments are shown. One perspective view in fig. 1 is a perspective view of the adhesive tape structure 1, and the other perspective view in fig. 2 is a front view of the adhesive tape structure 1 with respect to fig. 1.

Referring to fig. 1 and fig. 2, in an embodiment of the related art, the tape structure 1 includes a tape body 1a, and a carrier film 1b and a protection film 1c disposed on two sides of the tape body 1 a. The protective film 1c, the tape body 1a, and the carrier film 1b are sequentially laminated to form the tape structure 1. As shown in fig. 3, a plurality of tape structures 1 are typically stacked together to meet production requirements. As shown in fig. 4, when the tape is required to be attached, the pressure head P of the machine is driven, and the carrier film 1b of the uppermost tape structure 1 is adsorbed by the suction head Q on the pressure head P to pick up the tape structure 1. In this process, the situation that the plurality of adhesive tape structures 1 are taken out easily occurs, so that the machine cannot normally tear the protective film 1c according to a predetermined program, and the machine fails, thereby affecting the production process.

The inventor of the present application has noticed that, since the material of the protection film 1c and the material of the carrier film 1b are usually PET (polyethylene terephthalate), on one hand, static electricity is easily generated due to friction when the tape structure 1 is taken out, and on the other hand, the protection film 1c and the carrier film 1b have poor conductivity and are difficult to release after storing or generating static electricity. Therefore, when the tape structure 1 located at the uppermost layer is picked up, the adjacent tape structures 1 are easily attracted together by the static electricity.

In order to alleviate the problem of taking out a plurality of adhesive tapes due to the generated static electricity, the inventors of the present application have studied and found that a small amount of air can be introduced between adjacent adhesive tape structures to reduce the electrostatic attraction force generated between the adjacent adhesive tape structures. In particular, the problem of electrostatic attraction between adjacent tape structures can be alleviated in such a way that gaps can occur between adjacent tape structures.

Based on this, the present inventors have conducted extensive studies and designed an adhesive tape structure, in which a flexible sharp corner portion is provided on a protective film on the adhesive tape structure, so as to form the above-mentioned gap, thereby alleviating electrostatic adsorption between adjacent adhesive tape structures.

The structure of the adhesive tape provided by the embodiments of the present application will be further described with reference to the related drawings and some embodiments.

One view in fig. 5 is a front view of the tape structure 10, the other view in fig. 6 is a bottom view of the tape structure 10 relative to fig. 5, one view in fig. 7 is the same as the other view in fig. 6, and the other view in fig. 8 is a perspective view of the protective film 300 relative to fig. 5.

The first direction F1 illustrated in fig. 5 to 8 is a thickness direction of the tape structure 10, the second direction F2 is a length direction of the tape structure 10, and the third direction F3 is a width direction of the tape structure 10. The first direction F1, the second direction F2, and the third direction F3 are perpendicular to each other. This definition is used hereinafter and will not be described in detail.

In some embodiments, referring to fig. 5 to 8, an embodiment of the present disclosure provides an adhesive tape structure 10, where the adhesive tape structure 10 includes an adhesive tape body 100, a carrier film 200, and a protective film 300. The tape body 100 has a first surface 101 and a second surface 102 oppositely disposed along a first direction F1. The carrier film 200 covers the first surface 101. The protective film 300 covers the second surface 102. The protective film 300 includes a bonding region z1 bonded to the tape body 100 and a non-bonding region z2 surrounding the bonding region z 1. The protective film 300 has a plurality of sharp corners p provided in the non-bonded region z2, and the sharp corners p are configured by leaving a part of the protective film 300 through slits s formed in the protective film 300, and can be bent in a direction away from the tape body 100.

The tape body 100 is a member having both the first surface 101 and the second surface 102 having adhesiveness. The carrier film 200 is a member for carrying the adhesive tape body 100. When the adhesive tape structure 10 is sucked by the suction head Q, the adhesive tape structure 10 can be sucked by the carrier film 200, so as to prevent the suction head Q from damaging the adhesive tape body 100. The protective film 300 is used to protect the tape body 100. After the suction head Q adsorbs the tape structure 10, the protective film 300 on the tape structure 10 can be torn off, and then the tape body 100 can be attached to a desired product. After the attachment is completed, the carrier film 200 is torn off. The tape body 100, the carrier film 200 and the protective film 300 can be made of PET, and can be made of other materials corresponding to the corresponding functions, which is not limited in the embodiments of the present application.

Alternatively, in order to facilitate the peeling of the carrier film 200 and the protective film 300 from the tape body 100, the carrier film 200 and the protective film 300 may be provided as release films. For example, since the carrier film 200 needs to function as a carrier, the carrier film 200 may be configured as a heavy release film and the protective film 300 may be configured as a light release film. It is understood that the heavy release film and the light release film are relative. That is, the gram release of the carrier film 200 is greater than that of the protective film 300.

The attached region z1 is a region where the protective film 300 is in contact with the tape body 100, and the non-attached region z2 is a region where the protective film 300 is not in contact with the tape body 100. In fig. 7, the protective film 300 is divided into a bonded region z1 and a non-bonded region z2 by a boundary line d. The shape of the fitting region z1 is adapted to the shape of the tape body 100. It is understood that the shape and position of the fitting region z1 are related to the tape body 100. When it is necessary to align the tape body 100 with the edge of the protective film 300, the tape body can be attached as illustrated in fig. 7, and the non-attachment region z2 surrounds three sides of the attachment region z 1. If the tape body 100 needs to be disposed in the middle of the protection film 300 body, the middle region of the protection film 300 body is the attachment region z1, and at this time, the non-attachment region z2 surrounds the attachment region z 1.

Accordingly, the region of the carrier film 200 attached to the tape body 100 and the region not attached to the tape body 100 can also be understood by referring to the attached region z1 and the non-attached region z2 on the protection film 300, which are not described herein again. In order to avoid the situation that the carrier film 200 touches the product when the carrier film 200 is torn off, the tape body 100 and the carrier film 200 may be stacked by aligning the tape body 100 with the edge of the carrier film 200. Meanwhile, when the tape body 100 is laminated on the protective film 300, the tape body is aligned with the edge of the protective film 300, so that the tape body 100 can be further protected.

It is understood that, in order to facilitate the peeling of the carrier film 200 and the protective film 300, the area of the carrier film 200 and the area of the protective film 300 may be set to be larger than the area of the tape body 100. For example, as shown in fig. 9, fig. 9 shows a schematic projection diagram of the tape structure 10 according to an embodiment of the present application, defining a reference plane R as a plane perpendicular to the first direction F1, an orthogonal projection of the carrier film 200 on the reference plane R is a first projection Y1, an orthogonal projection of the protective film 300 on the reference plane R is a second projection Y2, an orthogonal projection of the tape body 100 on the reference plane R is a third projection Y3, an area of the first projection Y1 is equal to an area of the second projection Y2, and an area of the third projection Y3 is smaller than an area of the first projection Y1 and an area of the second projection Y2. The first projection Y1 and the second projection Y2 coincide with each other, and the third projection Y3 is located within the first projection Y1 and the second projection Y2. Of course, the size, the position, etc. of the carrier film 200, the protective film 300 and the adhesive tape body 100 may be set according to actual use requirements, and this is not particularly limited in this application.

The sharp corner p is provided in the non-adhering region z2 of the protective film 300, so that the tape body 100 is prevented from being damaged. The sharp corner portion p refers to a member having a sharp corner, at least both side edges of the sharp corner portion p meeting to form the sharp corner portion p having a sharp corner. In the case where the sharp corner portion p has a sharp corner, the sharp corner portion p is more likely to be deflected. The sharp corner p is formed by means of a slit s. And the slit s means that a slit at least two portions of which can be separated from each other is formed on the protective film 300. The slit s may be formed by, for example, cutting or removing a small portion of the protective film 300. The slit s penetrates the protective film 300 in the first direction F1. Taking fig. 6 to 8 as an example, the slit s is formed by a slit method. Alternatively, after the protection film 300 is cut by using a cutting stand to form the pointed portion p, the pointed portion p may be slightly warped due to its flexibility when the protection film 300 is lifted from the cutting stand, and when two adjacent tape structures 10 are laminated, a gap may be formed between the two adjacent tape structures 10 due to the flexible pointed portion p. In addition, since the sharp corner p is flexible, when the tape structure 10 is taken up, a gap may be formed between the tape structure 10 and the adjacent tape structure 10. Of course, the slit s may be formed in another manner, as long as the sharp corner p capable of being bent and remaining in the portion of the protective film 300 by the slit s is formed, and this embodiment of the present application is not particularly limited thereto.

Therefore, by providing the bendable sharp corner p on the protective film 300, when a plurality of tape structures 10 are stacked, a gap can be formed between two adjacent tape structures 10 by means of the sharp corner p, so that the electrostatic adsorption force between two adjacent tape structures 10 is reduced, the situation that the plurality of tape structures 10 are taken out is avoided, and the production efficiency is improved.

FIG. 10 is a schematic view showing the structure of a sharp corner p in a state in an embodiment of the present application; fig. 11 is a schematic structural view showing a sharp corner p in another state in an embodiment of the present application; for convenience of explanation, only matters related to the embodiments of the present application are shown. In order to clearly show the structure of the sharp corner portion p, a partial structure of the protective film 300 is shown in fig. 10 and 11, and one state in fig. 10 is a state in which the sharp corner portion p is not deflected and the other state in fig. 11 is a state in which the sharp corner portion p is deflected. Fig. 12 to 19, which are illustrated later, can also be understood as such, and are not described again.

In some embodiments, referring briefly to fig. 10 and 11, the slit s is configured to have intersecting first and second segments s1 and s2. The sharp corner p is formed by the first segment s1 and the second segment s2 intersecting. The first segment s1 and the second segment s2 intersect at an intersection point j. A sharp corner is formed at the position where the first segment s1 and the second segment s2 intersect. As shown in fig. 11, when the sharp corner p is bent, an opening k is formed in the protective film 300.

It is understood that the shape of the first segment s1 and the shape of the second segment s2 may be the same or different. The first segment s1 and the second segment s2 may be configured to include, but are not limited to, one or more of a straight line segment, a broken line segment, and a curved line segment. The embodiment of the present application is not particularly limited as long as the sharp corner portion p can be formed. Taking fig. 10 and 11 as an example, a case where the first segment s1 and the second segment s2 are configured as curved segments that are curved toward each other is illustrated. Taking fig. 12 and 13 as an example, fig. 12 illustrates a schematic structural view of a sharp corner p in one state in another embodiment of the present application, fig. 13 illustrates a schematic structural view of a sharp corner p in another state in another embodiment of the present application, and the first segment s1 and the second segment s2 are configured as curved segments curved away from each other. Taking fig. 14 and fig. 15 as examples, fig. 14 illustrates a structural view of a sharp corner portion p in one state in yet another embodiment of the present application, fig. 15 illustrates a structural view of a sharp corner portion p in another state in yet another embodiment of the present application, and the first segment s1 and the second segment s2 are configured as straight segments. The shape of the sharp corner p may be configured according to actual use conditions, and the embodiment of the present application does not particularly limit this.

FIG. 16 is a schematic view showing the structure of a sharp corner p in a state in yet another embodiment of the present application; FIG. 17 is a schematic view showing the structure of a sharp corner p in another state in still another embodiment of the present application; FIG. 18 is a schematic view showing a structure of a sharp corner p in a state in a further embodiment of the present application; fig. 19 shows a schematic view of the structure of a sharp corner p in another state in yet another embodiment of the present application; for convenience of explanation, only matters related to the embodiments of the present application are shown.

In some embodiments, each slit s may form at least one sharp corner p. Taking fig. 10 to 15 as an example, the illustrated slit s is formed with one sharp corner p. Taking fig. 16 and 17 as an example, the illustrated slit s is formed with two sharp corners p. Taking fig. 18 and 19 as an example, the illustrated slit s is formed with four pointed portions p. In contrast, the larger the number of the pointed portions p formed by one slit s, the larger the opening k formed in the region where the slit s is located, and thus the electrostatic attraction force between the adjacent tape structures 10 can be further reduced.

It is to be understood that, in the plurality of slits s provided in the protective film 300, all the slits s may have the same shape or different shapes, and may be provided according to actual use conditions, which is not particularly limited in the embodiment of the present application.

In some embodiments, with continued reference to fig. 18 and 19, the slit s has a first section s1 and a second section s2 intersecting with each other, and the slit s is formed with four pointed portions p, that is, the first section s1 and the second section s2 intersect to form four pointed portions p. It can be seen that the first segment s1 and the second segment s2 intersect at an intersection point j, the intersection point j divides the first segment s1 into a first sub-segment s11 and a second sub-segment s12, the intersection point j divides the second segment s2 into a third sub-segment s21 and a fourth sub-segment s22, and the first sub-segment s11, the second sub-segment s12, the third sub-segment s21 and the fourth sub-segment s22 form the four pointed portions p. In the case illustrated in fig. 18 and 19, the first segment s1 and the second segment s2 are both constructed as straight line segments, that is, the first segment s11, the second segment s12, the third segment s21 and the fourth segment s22 are also all straight line segments. Of course, the first segment s1 and the second segment s2 may be configured into a desired shape by referring to the content of some of the aforementioned embodiments, which is not particularly limited by the embodiments of the present application.

In some embodiments, with continued reference to fig. 14-19, the first segment s1 and the second segment s2 are constructed as straight segments. The first segment s1 and the second segment s2 configured as straight line segments may form at least one sharp corner p. Taking fig. 14 and 15 as an example, a case is illustrated where the first segment s1 and the second segment s2 configured as straight line segments are formed with one sharp corner portion p at which one end of the first segment s1 and one end of the second segment s2 intersect at the intersection point j. Taking fig. 16 and 17 as an example, a case is illustrated in which the first segment s1 and the second segment s2 configured as straight line segments are formed with two sharp corners p, in which case one end of the first segment s1 intersects with the middle of the second segment s2 at an intersection j, and the second segment s2 is divided into the third sub-segment s21 and the fourth sub-segment s22 by the intersection j. Taking fig. 18 and 19 as an example, a case is illustrated where the first section s1 and the second section s2 configured as straight line segments are formed with four sharp corners p, in which case the middle of the first section s1 and the middle of the second section s2 intersect at an intersection j, the intersection j divides the first section s1 into the first sub-section s11 and the second sub-section s12, and the intersection j divides the second section s2 into the third sub-section s21 and the fourth sub-section s22. In this way, the number of the corner portions p required can be obtained by the positions of the intersection points j.

In some embodiments, with continued reference to fig. 18 and 19, the midpoint of the first segment s1 is a first midpoint c1, the midpoint of the second segment s2 is a second midpoint c2, and the first midpoint c1 and the second midpoint c2 coincide with each other. That is, the first midpoint c1, the second midpoint c2, and the intersection j coincide. Thereby, the first segment s1 and the second segment s2 can be uniformly broken, respectively, to obtain the sharp corner portion p which is more flexible in a limited space. Whereas in the case illustrated in fig. 16 and 17, the intersection point j and the second midpoint c2 coincide with each other. Thus, the setting can be carried out according to the actual use condition.

In some embodiments, with continued reference to fig. 14-19, the first segment s1 and the second segment s2 are perpendicular to each other. That is, the first segment s1 and the second segment s2 intersect to form an included angle α, which is 90 degrees. This facilitates obtaining the sharp corner p which is more flexible. Meanwhile, while one slit s may form a plurality of the pointed portions p, the plurality of the pointed portions p may be constructed in a structure in which each of the pointed portions p can be deflected.

In some embodiments, with continued reference to fig. 14-19, the length of the first segment s1 is equal to the length of the second segment s2. By constructing the first section s1 and the second section s2 of the same length, the force-receiving environments to which the first section s1 and the second section s2 are exposed can be made substantially the same, and thus, the more flexible sharp corner p can be facilitated.

Optionally, with continued reference to fig. 14 to 19, the length of the first segment s1 and the length of the second segment s2 are both 5 mm. That is, the length of the first segment s1 is a first dimension L1, the length of the second segment s2 is a second dimension L2, and the first dimension L1 and the second dimension L2 are both 5 mm. In this way, the sharp corner p may not be formed on the first section s1 and the second section s2 having excessively short surfaces, and the phenomenon that the stiffness of the protective film 300 is reduced due to the excessively long first section s1 and the excessively long second section s2 and the function of the protective film 300 for protecting the tape body 100 is lost can be avoided.

As one embodiment, as shown in fig. 18 and 19, the slit s is configured as a first segment s1 and a second segment s2 that intersect. The first section s1 and the second section s2 are each constructed as straight line segments. The midpoint of the first segment s1 and the midpoint of the second segment s2 coincide at an intersection j, which divides the first segment s1 into a first sub-segment s11 and a second sub-segment s12, and the intersection j divides the second segment s2 into a third sub-segment s21 and a fourth sub-segment s22. The length of the first segment s1 and the length of the second segment s2 are equal, i.e. the length of the first segment s11, the length of the second segment s12, the length of the third segment s21 and the length of the fourth segment s22 are equal. The first section s1 and the second section s2 form an angle α of 90 degrees, i.e. the first section s11 and the third section s21 are perpendicular to each other, the first section s11 and the fourth section s22 are perpendicular to each other, the second section s12 and the third section s21 are perpendicular to each other, and the second section s12 and the fourth section s22 are perpendicular to each other. The first segment s1 and the second segment s2 intersect to form four sharp corners p having the same shape and size. The first segment s1 and the second segment s2 constitute a cross-shaped slit s. In such a slit s structure, when the openings k having the same size are obtained, more sharp corners p can be obtained, and the four obtained sharp corners p are more likely to be deflected.

In some embodiments, please continue to refer to fig. 6 to 8, all the slits s are uniformly arranged in the non-attaching region z2. It is to be understood that fig. 6 and 8 illustrate a case where all the slits s are substantially uniformly arranged and the plurality of slits s are arranged in a matrix in the non-attaching region z2. In this manner, access to the tape structure 10 is facilitated by the uniformly arranged slits s.

FIG. 20 shows a schematic view of a tape construction 10 of yet another embodiment of the present application; for convenience of explanation, only matters related to the embodiments of the present application are shown.

In some embodiments, referring to fig. 20, the non-attachment region z2 is divided into a middle region z21 and edge regions z22 located at both ends of the middle region z 21. The length of the intermediate region z21 in the second direction F2 is the same as the length of the tape body 100 in the second direction F2, the boundary of one side of the intermediate region z21 in the second direction F2 and the boundary of one side of the tape body 100 in the second direction F2 are overlapped with the first boundary line N1, and the boundary of the other side of the intermediate region z21 in the second direction F2 and the boundary of the other side of the tape body 100 in the second direction F2 are overlapped with the second boundary line N2. The distribution density of the slits s in the middle region z21 is greater than the distribution density of the slits s in the edge region z22. Since the edge region z22 is more likely to generate a gap than the middle region z21, the slits s located at the edge region z22 can be reduced to obtain a more rigid protective film 300. Of course, the distribution density of the slits s in the middle zone z21 is not large enough to avoid affecting the stiffness of the protection in the middle zone z 21. Alternatively, the slits s located in the middle region z21 may be uniformly arranged. Taking fig. 20 as an example, a case where the slits s located in the middle region z21 are arranged in a matrix is illustrated. The method can be set according to specific use conditions, and the method is not particularly limited by the embodiment of the application.

Fig. 21 shows a schematic projection of a protective film 300 according to an embodiment of the present application; for convenience of explanation, only matters related to the embodiments of the present application are shown.

In some embodiments, referring to fig. 21 in combination with fig. 6 to 8, a ratio of a total area of orthographic projections of all the sharp corners p on the reference plane R to an area of orthographic projections of a side surface of the protective film 300 facing away from the tape body 100 on the reference plane R is less than or equal to 0.4. The reference plane R is a plane perpendicular to the first direction F1. Taking fig. 18 and 19 as an example, two ends of the first segment s1 and two ends of the second segment s2 are sequentially connected to form a quadrilateral, that is, for a sharp corner p formed by the first segment s11 and the third segment s21, one end of the first segment s11 departing from the intersection j is connected to one end of the third segment s21 departing from the intersection j to form a virtual line i, and the sharp corner p can be regarded as being defined by the virtual line i, the first segment s11 and the third segment s 21. The remaining sub-segments may also be connected to form a virtual line i, which is not described herein in detail. Meanwhile, the sharp corner p and the imaginary line i illustrated in fig. 10 to 17 may also be referred to. In other words, in the case of the slits s illustrated in fig. 18 and 19, the area of the pointed portion p formed by one slit s can be regarded as the area of a quadrangle surrounded by four virtual lines i, the projection of the pointed portion p formed by one slit s is the fourth projection Y4, and the fourth projection Y4 is a quadrangle, that is, the case illustrated in fig. 21. As can be seen in fig. 21, the orthogonal projection of the protective film 300 on the reference surface R is a second projection Y2, and the fourth projection Y4 is located within the second projection Y2.

As described above, by controlling the area of the sharp corner portion p, the protective film 300 can satisfy the gap formation described above, and the protective film 300 can have a certain stiffness to better protect the tape body 100.

FIG. 22 shows a schematic view of the tape dispenser 10 of an embodiment of the present application; for convenience of explanation, only matters related to the embodiments of the present application are shown.

Taking fig. 22 as an example, when the suction head Q of the pressure head P picks up the tape structure 10 located at the uppermost layer, since a gap formed by the sharp corner P exists between the tape structure 10 located at the uppermost layer and the tape structure 10 adjacent thereto, air can enter between the two tape structures 10 along the path x, so that the electrostatic attraction between the two tape structures 10 is reduced, and further, the two tape structures 10 can be separated from each other, so that only the tape structure 10 located at the uppermost layer can be taken out.

To sum up, among the sticky tape structure 10 that this application embodiment provided, through set up the sharp bight p that can warp on protective film 300, when a plurality of sticky tape structures 10 pile up, can form the clearance with the help of sharp bight p between two adjacent sticky tape structures 10, reduced the static adsorption affinity between these two sticky tape structures 10, avoid these two sticky tape structures 10 the condition of adhesion to appear, and then avoid appearing taking out the situation of a plurality of sticky tape structures 10, reduced the board dyestripping unusual to production efficiency has been improved. Meanwhile, by controlling the distribution density and the shape structure of the sharp corners p, not only the flexible sharp corners p can be more conveniently formed, but also the protective film 300 can be kept to have a certain stiffness to protect the adhesive tape body 100. In this process, the slit s is only formed in the non-bonding region z2 of the protective film 300, and other structures are not added, so that the performance of the tape body 100 and the process of the tape structure 10 are not affected, and the cost is controllable.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, and these are all within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
