[0046] As can be seen from the background technology, the existing method of coating auxiliary material rolls still needs to be improved.
[0047] At present, the auxiliary material coating method is to cut the long roll auxiliary material into small sections less than 1 meter, and lay them flat in the coating chamber for coating. The cut auxiliary material is not suitable for continuous operation of automated production;
[0048] Another method is to use positioning posts to wind the long roll of auxiliary materials back and forth, which has low space utilization; there are many areas in contact with the positioning posts without gaps 201, and the film cannot be plated, which cannot meet the customer's shielding requirements; manual winding is slow and the production efficiency is low.
[0049] The inventors have found that the coated tape includes a first supporting surface and a second supporting surface relative to each other, and the surfaces of the first supporting surface and the second supporting surface respectively have a plurality of bosses; the coated tape is subsequently stacked together with the auxiliary material roll and rolled into a roll. Due to the presence of the bosses, sufficient gaps are left between the layers of the auxiliary material roll. During coating, protective (such as hydrophobic, oleophobic, corrosion-resistant, salt spray-resistant, etc.) materials enter from the gaps and are evenly attached to the surface of the auxiliary material, completing double-sided coating of the auxiliary material roll, which has a wider range of uses.
[0050] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0054] First, please refer to Figures 1 to 6 , a coated tape roll 100 includes a first supporting surface 100a and a second supporting surface 100b opposite to each other.

[0058] In this embodiment, the auxiliary material roll 200 includes a copper mesh, a cloth, a dustproof mesh, a sound-transmitting mesh, a non-woven fabric, aramid paper or other roll materials.
[0059] In this embodiment, the width of the first supporting surface 100a in the first direction is equal to the width of the second supporting surface 100b in the first direction, and the length of the first supporting surface 100a in the second direction is equal to the length of the second supporting surface 100b in the second direction.

[0061] In this embodiment, on the surface of the first supporting surface 100a, a plurality of the bosses 101 are distributed along the second direction X at the surface edge of the first supporting surface 100a. Specifically, adjacent bosses 101 in the first direction Y are symmetrically distributed along the second direction X at the surface edge of the first supporting surface 100a.
[0062] In other embodiments, the plurality of bosses 101 are distributed along the second direction X on one edge of the surface of the first supporting surface 100a, or the plurality of bosses 101 are distributed along the second direction X on two opposite edges of the surface of the first supporting surface 100a and are not symmetrically distributed in the second direction X.
[0063] In this embodiment, on the surface of the second supporting surface 100b, a plurality of the bosses 101 are distributed along the second direction X at the surface edge of the second supporting surface 100b. Specifically, adjacent bosses 101 in the first direction Y are symmetrically distributed along the second direction X at the surface edge of the second supporting surface 100b.
[0064] In other embodiments, the plurality of bosses 101 are distributed along the second direction X on one edge of the surface of the second supporting surface 100b, or the plurality of bosses 101 are distributed along the second direction X on two opposite edges of the surface of the second supporting surface 100b and are not symmetrically distributed in the second direction X.
[0065] In this embodiment, for the sake of convenience and clear description, the boss 101 located on the surface of the first supporting surface 100a is defined as a first boss 101a, and the boss 101 located on the surface of the second supporting surface 100b is defined as a second boss 101b.
[0066] In this embodiment, please refer to Figure 11 to Figure 12 The first boss 101a protrudes from the surface of the first supporting surface 100a, and the second boss 101b protrudes from the surface of the second supporting surface 100b. The coating tape 100 and the auxiliary material roll 200 are stacked together and rolled into a roll, so that sufficient gaps 201 are left between the layers of the auxiliary material roll 200. During coating, the protective material enters from the gap 201 and is evenly attached to the surface of the auxiliary material to complete the coating. It has a wide range of uses.
[0067] in, Fig.11 for Fig.10 A is a schematic diagram of the structure in the third direction, and the third direction is parallel to the central axis of the coating tape; Fig.12 for Fig.10 A is a schematic diagram of the structure in the fourth direction, and the fourth direction is perpendicular to the central axis of the coating roll.
[0068] In this embodiment, the coated tape 100 is a plastic coated tape, which can be specifically made of PET material, is easy to bend, can be bent repeatedly, and can be processed into the same length and width as auxiliary materials. At the same time, it can be superimposed and spliced into a longer tape, and has a wide range of applications.
[0069] In this embodiment, please refer to Figures 4 to 5 The cross-sectional shape of the surface of the boss 101 protruding from the supporting surface in the second direction X is spherical, that is, the cross-sectional shape of the surface of the first boss 101a protruding from the first supporting surface in the second direction X is spherical, and the cross-sectional shape of the surface of the second boss 101b protruding from the second supporting surface in the second direction X is spherical.
[0070] In this embodiment, the first boss 101a and the second boss 101b have the same shape.
[0071] In other embodiments, the shapes of the first boss 101a and the second boss 101b may be different.
[0072] In this embodiment, in the second direction X, the position where the first boss 101 a is projected onto the surface of the first supporting surface 100 a and the position where the second boss 101 b is projected onto the surface of the first supporting surface 100 a are spaced apart.
[0073] In other embodiments, in the second direction X, the position where the first boss 101a is projected onto the surface of the first supporting surface 100a and the position where the second boss 101b is projected onto the surface of the first supporting surface 100a may overlap.
[0074] In other embodiments, the cross-sectional shape of the surface of the boss 101 protruding from the support surface in the second direction X may also be spherical, rectangular, triangular, or trapezoidal, or a combination of multiple shapes.
[0075] In this embodiment, please refer to Figures 4 to 5 The cross-sectional shape of the surface of the boss 101 protruding from the supporting surface in the second direction X is spherical, which ensures that the supporting surface forms point contact with the auxiliary material without damaging the product surface, less obstruction to the auxiliary material roll, and greatly increases the coating area of the auxiliary material roll.
[0076] In this embodiment, please refer to Figure 11 to Figure 12 After the coating tape 100 and the auxiliary material roll 200 are put together, a large amount of space is left between each layer of auxiliary material, so that the coating material can smoothly enter the gap 201, deposit and adhere to the surface of the auxiliary material to form a protective film, which greatly improves the protective performance of the auxiliary material.
[0077] In this embodiment, please refer to Figure 3 and Figure 6 , further comprising a reinforcing rib 102 located on the surface of the first supporting surface 100a or the surface of the second supporting surface 100b, and the reinforcing rib 102 extends along the first direction Y.
[0078] In this embodiment, the reinforcing ribs 102 are located on the surface of the first supporting surface 100a.
[0079] In other embodiments, the reinforcing ribs 102 may also be located on the surface of the second supporting surface 100b; or the reinforcing ribs 102 may be located on the surfaces of the first supporting surface 100a and the second supporting surface 100b respectively.
[0080] In this embodiment, the reinforcing ribs 102 are used to improve the strength of the coated tape 100 to prevent the first supporting surface 100 a or the second supporting surface 100 b from bending, thereby avoiding damage to the surface of the auxiliary material roll 200 .
[0081] In this embodiment, the protrusion height of the reinforcing rib 102 on the surface perpendicular to the first supporting surface 100a is smaller than the protrusion height of the boss 101 in the direction perpendicular to the surface of the first supporting surface 100a; on the one hand, the reinforcing rib 102 is used to enhance the strength of the first supporting surface 100a; on the other hand, the protrusion height of the reinforcing rib 102 on the first supporting surface 100a is set to be smaller than the protrusion height of the boss 101, thereby ensuring that there is only point contact between the first supporting surface 100a and the auxiliary material roll 200, reducing the obstruction of the auxiliary material roll 200.
[0082] In other embodiments, when the reinforcing rib 102 is located on the surface of the second supporting surface 100b, the protruding height of the reinforcing rib 102 perpendicular to the surface of the second supporting surface 100b is smaller than the protruding height of the boss 101 perpendicular to the surface of the second supporting surface 100b.
[0083] In this embodiment, please refer to Figures 1 to 3 , further comprising a through hole 103 extending from the surface of the first supporting surface 100 a through the surface of the second supporting surface 100 b , wherein the through hole 103 is located between adjacent reinforcing ribs 102 .
[0084] In this embodiment, the shape of the through hole 103 projected onto the surface of the first supporting surface 100 a is a rectangle.
[0085] In other embodiments, the shape of the through hole 103 projected onto the surface of the first supporting surface 100a includes one or more combinations of rectangle, circle or triangle.
[0086] In this embodiment, the through hole 103 serves as air permeability. When the gaps 201 between layers of the auxiliary material roll 200 are filled, the first supporting surface 100a and the second supporting surface 100b occupy less space, and the protective material can more easily enter the gaps 201 of the auxiliary material roll 200, thereby achieving a good coating effect.
[0087] In this embodiment, please refer to Figure 3 , the width (d1) of the through hole 103 in the first direction Y is smaller than the width (d2) of the first supporting surface 100a in the first direction Y, and the length (L1) of the through hole 103 in the second direction X is smaller than the spacing (L2) between adjacent reinforcing ribs 102 in the second direction X.
[0088] Correspondingly, the present invention also provides an auxiliary material winding device 300, please refer to Figure 8, including the above-mentioned coated tape 100, the coated tape 100 includes a first supporting surface 100a and a second supporting surface 100b opposite to each other, and the surface of the first supporting surface 100a and the surface of the second supporting surface 100b respectively have a plurality of bosses 101.

[0090] In this embodiment, please continue to refer to Figure 7 and Figure 8 , and also includes a winding disk 304 fixed to the driving wheel 303, one end of the auxiliary material roll 200 and one end of the coating tape 100 are overlapped and fixed to the axis core of the winding disk 304, and the surface of the auxiliary material roll 200 is in contact with the boss 101.
[0091] In this embodiment, the material reel 304 is fixed on the driving wheel 303 of the automatic material winding device 300, the material reel 200 and the coated tape 100 are respectively fixed on the driven wheels (the first driven wheel 301 and the second driven wheel 302), the ends of the material reel 200 and the coated tape 100 are respectively extracted, and the ends are superimposed and fixed on the shaft core of the material reel 304, the automatic material winding device 300 is turned on and a suitable speed is selected, the winding of the material reel 200 can be automatically completed until it is full, the fully rolled material reel 304 is taken out and the end of the material reel 200 is fixed, and the winding process is completed, the material reel 200 and the coated tape 100 are wound up (please refer to Fig. 9 ).
[0092] In this embodiment, please refer to Figure 7 The baffles on both sides of the coil tray 304 are mesh-shaped, and the purpose is to allow the coating material to smoothly pass through the coil tray 304 and enter the gap 201 of the auxiliary material roll 200 opened by the boss 101, and deposit and adhere to the surface of the auxiliary material roll 200.
[0093] In this embodiment, the length of a full roll of auxiliary material 200 is calculated as follows:
[0094] The core diameter of the coiling disc 304, i.e., the inner diameter d of the fully wound auxiliary material roll 200, is set to 50 mm; the outer diameter of the coiling disc 304, i.e., the outer diameter D of the fully wound auxiliary material roll 200, is set to 360 mm; the thickness M of the coated tape 100 is set to 6 mm; the thickness N of the auxiliary material roll 200 is set to 0.3 mm;
[0095] Full roll of auxiliary material 200 length = (3.14xDxD / 4-3.14xdxd / 4) / (M+N)
[0096] =(3.14x360x360 / 4-3.14x50x50 / 4) / (6+0.3)
[0097] =15837mm.
