[0005] 2. Product quality is affected: If the scale markings are damaged or inaccurate, it may affect the quantitative accuracy of the components, thereby affecting the production quality of electronic components.

[0006] 3. Accuracy of mark position: If the position of the scale mark is not accurate enough or is easily disturbed and offset, the sensor may not be able to correctly identify the position of the mark, thus affecting the accurate calculation of the number of remaining electronic components.

[0007] 4. Interference between marks: If the scale marks on the tape are too dense or overlapped, the sensor may have difficulty accurately distinguishing and identifying each mark, thus affecting the accuracy of the count.

[0008] 5. Tape bending and deformation: The tape may be bent and deformed during the production process, which may change the shape and position of the scale marks, thereby affecting the recognition effect of the sensor. Utility Model Content

[0015] In one embodiment, when the starting end of the material is offset from the position of the marking portion by a position relationship (Y), the following formula (2) is used to compensate the remaining length (L n ):

[0016]

[0017] Among them, Y is less than 1 and greater than 0.

[0018] In one embodiment, the marking portion has n first scales, which are disposed on the same side of the plate body and the shaft portion, and the first scales start from the outer peripheral side of the shaft portion and extend sequentially toward the outer peripheral side of the plate body.

[0019] In one embodiment, the marking portion has n second scales disposed on the other side of the plate body opposite to the shaft portion, and the second scales extend sequentially from the outer peripheral side of the shaft portion toward the outer peripheral side of the plate body.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0036] First, see Figures 1 to 3 2 is a first embodiment of the present invention, which is a reel with a marking structure for carrying a long strip of material 40 with a certain thickness. The reel mainly includes a plate 10 , a shaft 20 and a marking portion 30 .

[0037] The plate 10 is in a flat rectangular shape and has a predetermined area. The thickness of the plate 10 is between 10 mm and 20 mm, so as to carry and support the material 40. In other possible implementations, the plate 10 may also be circular or have other geometric shapes.

[0038] The shaft portion 20 is cylindrical and coaxially protrudes from the center of the plate body 10 . The area of ​​the shaft portion 20 in its radial section is smaller than that of the plate body 10 .

[0039] Furthermore, the plate body 10 and the shaft portion 20 are integrally formed, and the material of the plate body 10 and the shaft portion 20 are both non-magnetic conductive materials, such as paper or plastic. Such a design ensures that the structure of the tape reel is simple and strong, while avoiding magnetic interference with the electronic components, thereby ensuring the integrity and quality of the electronic components.

[0040] The marking portion 30 is radially disposed on the plate body 10 and is located between the outer peripheral side surface of the plate body 10 and the outer periphery of the shaft portion 20. Specifically, the marking portion 30 has n first scales 31 disposed on the same side surface of the plate body 10 and the shaft portion 20, and the first scales 31 are sequentially extended toward the outer peripheral side surface of the plate body 10 starting from the outer peripheral side surface of the shaft portion 20, such as Figure 3 shown.

[0041] The material 40 is a rolled strip. Specifically, the material 40 is a magnetic ruler and carries a predetermined number of electronic components. When the material 40 is wound around the outer periphery of the shaft 20, a starting end 41 of the material 40 overlaps with the position of the marking portion 30, and the material 40 is wound layer by layer in sequence. Figure 3 shown.

[0042] Accordingly, the operator uses the number of turns of the belt body to cover the entire or partial portion of the marking portion 30 as a reference to obtain a remaining length (L) of the material 40 on the shaft portion 20. n ), the remaining length (L n ) satisfies the following formula (1):

[0043]

[0044] Wherein, X is the thickness of the material 40 (e.g. Figure 3 ), D is the outer diameter of the shaft 20 (as shown Figure 3 As shown), n is the number of winding layers of the material 40, n is a positive integer, and L1 is zero.

[0045] Furthermore, each of the first scales 31 is further marked with a mark corresponding to the number of winding layers of the material 40, such as L1, ..., L n Or 1, 2, ..., n or a combination thereof. In this embodiment, if Figure 3 As shown, the number of winding layers is marked as 1.L (hidden in the figure), ..., 5.L5, 6.L6, ..., 14.L14, and so on, so that the operator can more intuitively confirm the remaining length (L n ).

[0046] In addition, the first scales 31 and related marks are formed on the board 10 by using imaging, offset printing, printing, laser or related technologies.

[0047] like Figure 4 As shown, it is the second embodiment of the utility model. The main difference between the second embodiment and the first embodiment is that the starting end 41A of the material 40A and the position of the marking portion 30A are offset by a position relationship (Y). The position relationship (Y) refers to the proportional relationship between the position of the starting end 41A of the material 40A and the reference on the circumference of the shaft portion 20B with the position of the marking portion 30A as the reference, wherein Y is less than 1 and greater than 0. For example, when Y is 1 / 4, it means that the two are offset by 1 / 4 of a circle; when Y is 1 / 3, it means that the two are offset by 1 / 3 of a circle; and so on, and the following formula (2) is used to compensate the remaining length (L n ):

[0048]

[0049] Furthermore, different locations on the marking portion 30A can be used as references, such as the center, periphery, or any other location of the marking portion 30A. In this example, the center of the marking portion 30A is used as the reference point.

[0050] like Figure 5 and Figure 6As shown, it is the third embodiment of the utility model, and the main difference between it and the first embodiment is that the marking portion 30B has n second scales 32 and an elongated through hole 33, wherein the second scales 32 are arranged on the other side of the plate body 10B opposite to the shaft portion 20B, and the second scales 32 are sequentially extended from the outer peripheral side of the shaft portion 20B to the outer peripheral side of the plate body 10B. The second scales 32 are formed on the plate body 10B by using images, offset printing, printing, laser or related technologies.

[0051] The elongated through hole 33 is formed on the plate body 10B adjacent to the second scales 32 , and the elongated through hole 33 starts from the outer peripheral side surface of the shaft portion 20B and extends toward the outer peripheral side surface of the plate body 10B.

[0052] Accordingly, the operator can observe and confirm the number of turns of the material 40B wound around the shaft portion 20B through the elongated through hole 33, and obtain the remaining length (L) by using the second scales 32 as a reference. n ).

[0053] like Figure 7 As shown, it is the fourth embodiment of the utility model, and the main difference between it and the third embodiment is that the number of the marking portions 30C is four, and each of the marking portions 30C is spaced apart from the shaft portion 20C on the circumference in a predetermined ratio configuration, and the predetermined ratio configuration refers to four equal divisions, and each of the marking portions 30C is radially adjacent to the shaft portion 20C. In other possible implementations, the number of the marking portions 30C can be two, or any number above two. For example, when the number of the marking portions 30C is two, the predetermined ratio configuration is two equal divisions, or other options (such as asymmetric designs or arbitrary positions). When the number of the marking portions 30C is any number above two, the predetermined ratio configuration is defined according to the aforementioned equal division method or other options.

[0054] Furthermore, the starting end of the material 40C can be located at different positions of the marking portion 30C, and the remaining length (L n ). For example, one of the marking portions 30 is used as a reference and marked as 0, and the other marking portions 30C are marked as 1 / 4, 2 / 4, and 3 / 4 respectively compared with the marking portion 30C used as the reference. When the starting end of the material 40C is located on the marking portion 30C marked as 1 / 4, Y in formula (2) is 1 / 4; when the starting end of the material 40C is located on the marking portion 30C marked as 3 / 4, Y in formula (2) is 3 / 4; and so on.

[0055] like Figure 8As shown in the figure, it is the fifth embodiment of the utility model, and the main difference between it and the first embodiment is that the marking portion 30D is in the shape of concentric circles. Specifically, the marking portion 30D has n concentric circle scales 34 and a plurality of marks 35, wherein the concentric circle scales 34 are arranged in sequence from the outer peripheral side of the shaft portion 20D to the outer peripheral side of the plate body 10D with the center position of the plate body 10D as the center of the circle, and each of the marks 35 is respectively arranged at a predetermined position of the plate body 10D between two adjacent concentric circle scales 34, and each of the marks 35 can be any one of a mark, a pattern, a text, a number or any combination thereof, such as 0m, 1m, 2m, 3m, ..., etc., to respectively indicate the remaining length (L) represented by different marks 35. n ). Accordingly, when the end of the material 40C is located at the position of one of the marks 35, the operator can directly read the remaining length (L n ).

[0056] Each of the concentric circle scales 34 and each of the marks 35 is formed on the plate 10D by using imaging, offset printing, printing, laser or related technology.

[0057] In addition, the utility model further provides a sixth embodiment, which is different from the first embodiment in that the plate is made of transparent plastic material, allowing light to penetrate. Accordingly, the operator can observe from the other side of the plate that is opposite to the material, and can also obtain the remaining length (L n ).

[0058] In addition, the present invention can also use a sensor or an image capture device to obtain the relationship between the marking portion and the material, and then use a computing device to identify, analyze and calculate to obtain the remaining length (L n ).

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
