Abstract
Description
Technical Field
[0001] This application relates to the field of packaging technology, and more particularly to a reel. Background Technology
[0002] In the field of electronic packaging technology, electronic components are typically stored in pockets of carrier tape, which is then wound into the cavity of a reel. The reel is then wrapped with a packaging bag for the storage and transportation of the electronic components.
[0003] Currently, the reel is a single-reel structure with only one reel cavity. A single reel can only wind one carrier tape, resulting in a small carrier tape capacity. Furthermore, after the reel winds the carrier tape, it is usually packaged in an individual bag, which leads to a small carrier tape capacity in a single bag and high packaging costs.
[0004] To increase the carrier tape capacity within a single packaging bag and reduce packaging costs, related technologies employ a "one bag, multiple reels" packaging model, packing multiple reels into the same bag. However, due to the lack of axial restraint among multiple reels, carrier tape shifting can easily occur, tearing the packaging bag and leading to uncontrollable packaging costs and airtightness failure. Utility Model Content
[0005] This application provides a reel to solve the problems existing in the related technology, where the lack of axial restraint on multiple reels inside the packaging bag easily leads to carrier belt displacement and tearing of the packaging bag, resulting in uncontrollable packaging costs and failure of airtightness.

[0011] In one embodiment, in each group of multiple latches, each latch is located between two adjacent latch holes; in each group of multiple latch slots, each latch slot is located between two adjacent latch strips; and / or, the latches of the first to the (N-1)th baffles all protrude toward the first side surface of the corresponding baffle, and the latch of the Nth baffle protrude toward the second side surface of the Nth baffle; and / or, the distance between two adjacent groups of latch slots in the first group to the (N-1)th group is equal, and the distance between two adjacent groups of latch slots in the first group to the (N-1)th group is equal. The distance between the N-1th group of slots and the Nth group of slots is greater than the distance between them, and the difference between them is equal to the sum of the dimension of the Nth group of slots in the axial direction of the reel and the thickness of the Nth baffle; and / or, the second side surface of the first baffle is coplanar with the end face of the first end of the reel, and the first side surface of the Nth baffle is coplanar with the end face of the second end of the reel; and / or, the height difference between the second side surface of the first baffle and the end face of the first end of the reel and the height difference between the first side surface of the Nth baffle and the end face of the second end of the reel are less than or equal to 0.1 mm.
[0012] In one embodiment, the spool is a hollow tubular structure, the outer diameter of the spool is smaller than the diameter of the mounting hole, the outer diameter of the spool ranges from 14.5mm to 16.5mm, and the diameter of the mounting hole ranges from 15.5mm to 17.5mm.
[0013] In one embodiment, the dimension of the card strip in the radial direction of the spool is less than or equal to the dimension of the card hole in the radial direction of the corresponding baffle. The range of the dimension of the card strip in the radial direction of the spool and the range of the dimension of the card hole in the radial direction of the corresponding baffle are both 5mm to 6mm.

The structure defines the cavities of a single reel by having each reel and its corresponding two baffles define cavities outside the reel. This structure not only increases the number of cavities in a single reel to N-1, allowing a single reel to wind N-1 carrier tapes and thus effectively increasing the carrier tape capacity of a single reel, but also fixes the N baffles along the axial direction of the reel, ensuring that the N-1 reels and N-1 cavities are constrained along the axial direction of the reel. This makes it difficult for the N-1 carrier tapes to shift after winding, thus preventing the carrier tapes from tearing the packaging bag after packaging. This facilitates the control of packaging costs and ensures that the airtightness of the packaging bag is not compromised. Attached Figure Description

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.
[0027] Figure 1 The diagram shown is a perspective view of the overall structure of a reel according to an embodiment of this application. Figure 2 The figure shown is a three-dimensional structural diagram of the roll in one embodiment of this application. Figure 3 As shown Figure 2 A schematic diagram of the cross-sectional structure of the middle drum.
[0028] Please refer to the following: Figures 1 to 7 The reel 10 includes a spool 11, N baffles 12 and N-1 drums 13.
[0029] The scroll 11 has a first end 11A and a second end 11B. The scroll 11 has N sets of slots 112 recessed in its shaft wall. The N sets of slots 112 are arranged at intervals along the axial direction A1 of the scroll 11. The axial direction A1 of the scroll 11 is the direction from the first end 11A to the second end 11B.
[0030] Each baffle 12 has a mounting hole 121 in its center, and each mounting hole 121 has a set of latches 123 on its wall. The scroll 11 is inserted into the mounting hole 121 of each baffle 12, and the N sets of latches 123 are engaged with the N sets of slots 112 one by one, so that the N baffles 12 are sleeved on the outside of the scroll 11 at intervals along the axial direction A1; N is an integer greater than or equal to 3. For example, N can be an integer such as 3, 4, 5, 6, etc., and N is preferably 5. The number of baffles 12 can be selected and adjusted according to actual needs, and this application embodiment does not limit this. The shape of the baffle 12 includes, but is not limited to, circles, ellipses, rectangles, and regular polygons.
[0031] Each roller 13 is coaxially disposed between two adjacent baffles 12, so that each roller 13 and the corresponding baffles 12 define a winding cavity 13A outside the roller 13. For example, the first roller 13 is coaxially disposed between the first baffle 12 and the second baffle 12. The outer wall of the first roller 13, the area of the first baffle 12 outside the roller 13, and the area of the second baffle 12 outside the roller 13 define the first winding cavity 13A. Similarly, the outer wall of the i-th roller 13, the area of the i-th baffle 12 outside the roller 13, and the area of the (i+1)-th baffle 12 outside the roller 13 define the i-th winding cavity 13A, where 2≤i≤N-1, and i is an integer. In this way, N-1 rollers 13 and N baffles 12 can define a total of N-1 winding cavities 13A. In use, the carrier tape is wound up using the drum 13 and the wound carrier tape is contained in the winding cavity 13A.
[0032] In the above solution, because the shaft wall of the spool 11 has N sets of slots 112 arranged at intervals along the axial direction of the spool 11, and each of the N baffles 12 has a mounting hole 121 in the middle, and a set of buckles 123 is provided on the wall of each mounting hole 121, when the spool 11 is inserted into the mounting holes 121 of each baffle 12, and the N sets of buckles 123 are engaged with the N sets of slots 112 one by one, the N baffles 12 can be spaced and fixed outside the spool 11 at intervals along the axial direction A1 of the spool 11, thus preventing the N baffles 12 from shifting along the axial direction A1 of the spool 11; in addition, by coaxially arranging the spools between two adjacent baffles 12... The drum 13 is used to define the winding cavity 13A in the area outside the drum 13 with the corresponding two baffles 12. This structure can not only increase the number of winding cavities 13A of a single drum 10 to N-1, so that a single drum 10 can wind N-1 carrier tapes, thereby effectively increasing the carrier tape capacity of a single drum 10, but also fix the N baffles 12 along the axial direction A1 of the shaft 11, ensuring that the N-1 drums 13 and N-1 winding cavities 13A are constrained along the axial direction A1 of the shaft 11, so that the N-1 carrier tapes after winding are not easily displaced, and thus the carrier tapes are not easily torn in the packaging bag after packaging, making it easier to control packaging costs and ensure that the airtightness of the packaging bag does not fail.
[0033] In one implementation, please refer to Figures 1 to 5 N-1 rollers 13 are arranged one-to-one on the first side surface of the first baffle 12 to the N-1th baffle 12, and the Nth baffle 12 is sleeved on the second end 11B of the roller 11; the first side surface of the baffle 12 is the side surface of the baffle 12 facing the second end 11B of the roller 11.
[0034] The first to the (N-1)th baffles 12 and their respective drums 13 can be an integral structure, so that the first to the (N-1)th baffles 12 are first baffle structures 12A with drums 13 on their first side surface, while the Nth baffle is a second baffle structure 12B without drums 13.
[0035] In related technologies, each reel includes a spool and two baffles located at both ends of the spool, and each reel can only wind up one carrier tape. If the reels using related technologies wind up N-1 carrier tapes, then N-1 reels are required, and N-1 reels will consume a total of N-1 spools and 2N-2 baffles, and will occupy a large amount of space.
[0036] Compared to related technologies, this application can achieve the packaging structure of N-1 reels coaxially integrated by arranging N-1 differentiated first baffle structures 12A and 1 second baffle structure 12B at intervals along the axial direction A1 of the modular reel 11, which is beneficial to reduce manufacturing costs and optimize space functionality.
[0037] In one implementation, please refer to Figures 1 to 7 The spool 11 has multiple retaining strips 111 protruding from its shaft wall. These strips extend along the axial direction A1 of the spool 11 and are spaced apart along its circumference. The spool 11 can be made of any of the following materials: polycarbonate (PC), polystyrene (PS), ABS plastic, or high-impact polystyrene (HIPS).
[0038] Each baffle 12 has multiple locking holes 122 in its center. These holes 122 penetrate the first and second side surfaces of the corresponding baffle 12. The locking holes 122 are spaced apart circumferentially along the mounting holes 121 and communicate with them. The second side surface of the baffle 12 is the side surface facing the first end 11A of the scroll 11. Multiple locking strips 111 are inserted one-to-one into the locking holes 122 of each baffle 12.
[0039] Preferably, multiple card strips 111 are arranged at equal intervals along the circumference of the roll 11, and multiple card holes 122 are arranged at equal intervals along the circumference of the corresponding mounting holes 121.
[0040] The above solution involves setting multiple retaining strips 111 to protrude outward from the shaft wall of the spool 11, with the multiple retaining strips 111 extending along the axial direction A1 of the spool 11 and arranged at intervals along the circumference of the spool 11. Multiple retaining holes 122 are located in the center of each baffle 12, and these holes 122 penetrate the first and second side surfaces of the corresponding baffle 12. The multiple retaining holes 122 are arranged at intervals along the circumference of the mounting holes 121 and communicate with the mounting holes 121. This allows the multiple retaining strips 111 on the spool 11 to be inserted one-to-one into the multiple retaining holes 122 of each baffle 12 when the spool 11 is inserted into the mounting holes 121 of each baffle 12, thereby fixing the position of each baffle 12 in the circumference of the spool 11 and preventing the baffles 12 from shifting in the circumference of the spool 11.
[0041] In one implementation, please refer to Figures 1 to 7 Each group of slots 112 comprises multiple slots, which are arranged at intervals along the circumference of the scroll 11. Each group of buckles 123 comprises multiple buckles, which are arranged at intervals along the circumference of the mounting holes 121 of the corresponding baffles 12. Each group of buckles 123 engages one-to-one with the corresponding slots 112. This structure locks each baffle 12 onto the scroll 11 by engaging its respective buckles 123 with the corresponding slots 112.
[0042] For preferred options, please refer to [link / reference]. Figure 2 and Figure 3 The multiple slots 112 in each group are arranged at equal intervals along the circumference of the scroll 11. Please refer to [link / reference]. Figures 4 to 7 The multiple latches 123 in each group are arranged at equal intervals along the axial direction of the mounting holes 121 of the corresponding baffle 12. In this way, when the multiple latches 123 in each group are engaged with the multiple slots 112 in the corresponding group, the engagement is improved.
[0043] In one alternative implementation, please refer to Figures 4 to 7 In each group of multiple latches 123, each latch 123 is located between two adjacent latch holes 122 of the corresponding baffle 12; please refer to Figure 2 Zhihe Figure 3 In each group of multiple slots 112, each slot 112 is located between two adjacent slot strips 111. In this way, multiple buckles 123 are evenly distributed on the hole walls of the corresponding mounting holes 121, and multiple slots 112 are evenly distributed in the circumferential direction of the roll 11, which helps to improve the firmness of the engagement between the multiple buckles 123 of each group and the multiple slots 112 of the corresponding group.
[0044] In one alternative implementation, please refer to Figure 1 , Figures 4 to 7 The latches 123 of the first to N-1th retaining plates 12 all protrude toward the first side surface of the corresponding retaining plate 12, and the latches 123 of the Nth retaining plate 12 protrude toward the second side surface of the Nth retaining plate 12. This structure facilitates the sequential assembly of the first to Nth retaining plates 12 along the axial direction of the spool 11, and helps ensure that the second side surface of the first retaining plate 12 is flush with the end face of the first end 11A of the spool 11 after assembly, and that the first side surface of the Nth retaining plate 12 is flush with the end face of the second end 11B of the spool 11.
[0045] In one alternative implementation, please refer to Figures 1 to 3The distance S1 between any two adjacent card slots 112 in the first group of card slots 112 to the (N-1)th group of card slots 112 is equal. The distance S1 between any two adjacent card slots 112 in the first group of card slots 112 to the (N-1)th group of card slots 112 is greater than the distance S2 between the (N-1)th group of card slots 112 and the Nth group of card slots 112. The difference between the two is equal to the sum of the dimension of the Nth group of card slots 112 in the axial direction (A1) of the scroll 11 and the thickness of the Nth baffle 12. In this way, the installation positions of N baffles 12 can be accurately located by the positions of N slots 112. Then, after the multiple buckles 123 of the first baffle 12 to the Nth baffle 12 are engaged one by one with the multiple buckles 123 in the first group of slots 112 to the Nth group of slots 112, it can be ensured that the distance S between any two baffles 12 in the first baffle 12 to the Nth baffle 12 is equal, so as to achieve the equal spacing arrangement of N baffles 12.
[0046] In one alternative implementation, please refer to Figure 1 The second side surface of the first baffle 12 is coplanar with the end face of the first end 11A of the scroll 11, and the first side surface of the Nth baffle 12 is coplanar with the end face of the second end 11B of the scroll 11.
[0047] Specifically, the coplanarity of the second side surface of the first baffle 12 with the end face of the first end 11A of the spool 11 and the coplanarity of the first side surface of the Nth baffle 12 with the end face of the second end 11B of the spool 11 can be: the flatness between the second side surface of the first baffle 12 and the end face of the first end 11A of the spool 11, and the flatness between the first side surface of the Nth baffle 12 and the end face of the second end 11B of the spool 11, is less than or equal to 0.1 mm. Preferably, this flatness can be 0.05 mm.
[0048] Therefore, by packaging the reel 10 with a packaging bag, it is possible to prevent the ends of the reel 10 from being scratched or torn by the packaging bag, which helps to reduce the damage rate of the packaging bag and ensure that the airtightness of the packaging bag does not fail.
[0049] In one implementation, please refer to the following: Figures 2 to 4 The spool 11 is a hollow tubular structure. The outer diameter D1 of the spool 11 is smaller than the diameter D2 of the mounting hole 121, and the outer diameter D1 of the spool 11 ranges from 14.5mm to 16.5mm (inclusive), while the diameter D2 of the mounting hole 121 ranges from 15.5mm to 17.5mm (inclusive). For example, the outer diameter D2 of the spool 11 can be any value among 14.5mm, 14.9mm, 15.1mm, and 16.5mm, and the diameter D2 of the mounting hole 121 can be any value among 15.5mm, 16mm, 16.5mm, 17mm, and 17.5mm.
[0050] The above solution reduces the weight and material usage of the roll 11 by setting it to a hollow tubular structure, thereby lowering packaging costs. Furthermore, by setting the outer diameter D1 of the roll 11 to be smaller than the diameter D2 of the mounting hole 121, and setting the outer diameter D1 of the roll 11 to a range of 14.5mm to 16.5mm, and the diameter D2 of the mounting hole 121 to a range of 15.5mm to 17.5mm, the outer diameter D1 of the roll 11 and the outer diameter D2 of the mounting hole 121 are not significantly different, making it easier to insert the roll 11 into the mounting hole 121 and reducing assembly difficulty.
[0051] In one implementation, please refer to the following: Figure 2 and Figure 3 The radial dimension H1 of the locking strip 111 on the reel 11 is less than or equal to the radial dimension H2 of the locking hole 122 on the corresponding stop plate 12. The range of both the radial dimension H1 of the locking strip 111 and the radial dimension H2 of the locking hole 122 on the corresponding stop plate 12 is 5mm to 6mm (inclusive). The range of both the width W1 of the locking strip 111 and the width W2 of the locking hole 122 is 4.5mm to 5mm (inclusive). For example, the radial dimension H1 of the locking strip 111 on the reel 11 can be any value among 5mm, 5.5mm, and 6mm. The radial dimension H2 of the locking hole 122 on the corresponding stop plate 12 can be any value among 5mm, 5.5mm, and 6mm. The width W1 of the locking strip 111 and the width W2 of the locking hole 122 can be any value among 4.5mm, 4.8mm, and 5mm. In this way, the dimension H1 of the card strip 111 in the radial direction of the scroll 11 can be matched with the dimension H2 of the card hole 122 in the radial direction of the corresponding baffle 12, and the width W1 of the card strip 111 can be matched with the width W2 of the card hole 122, so that the card strip 111 can be inserted into the card hole 122.
[0052] In one implementation, please refer to the following: Figure 2 and Figure 3 The distance W3 between the two inner sidewalls of the card strip 111 ranges from 2.5mm to 3mm (including the endpoint value). For example, the distance W3 between the two inner sidewalls of the card strip 111 can be any value among 2.5mm, 2.8mm, and 3mm.
[0053] In one implementation, please refer to Figure 1 N baffles 12 are equally spaced along the axial direction A1 of the roll 11. The distance S between two adjacent baffles 12 is greater than the width of the carrier belt, and the difference between the distance S between two adjacent baffles 12 and the width of the carrier belt is 2mm to 3mm (including the end value).
[0054] Taking a carrier tape width of 12mm as an example, the difference between the spacing S between two adjacent baffles 12 and the width of the carrier tape ranges from 2mm to 3mm, and the spacing S between two adjacent baffles 12 can range from 14mm to 15mm (including the endpoint value). The difference between the spacing S between two adjacent baffles 12 and the width of the carrier tape can be any value among 2mm, 2.5mm, and 3mm. This difference can be selected and adjusted according to actual needs, and this embodiment does not impose any limitations on it.
[0055] The above solution, by setting the distance S between two adjacent baffles 12 to be greater than the width of the carrier belt, and making the difference between the distance S between two adjacent baffles 12 and the width of the carrier belt range from 2mm to 3mm, can make the size of the winding cavity 13A defined by the two adjacent baffles 12 and the drum 13 located between them slightly larger than the width of the carrier belt in the axial direction A1 of the roller 11. This not only avoids the two adjacent baffles 12 from blocking the winding of the carrier belt, but also confines the wound carrier belt within the winding cavity 13A, preventing the carrier belt from shifting.
[0056] In one embodiment, the width of the carrier tape ranges from 8 mm to 24 mm (inclusive). For example, the width of the carrier tape can be any value among 8 mm, 10 mm, 12 mm, 16 mm, 20 mm, and 24 mm. In this way, the cavity 13A defined by two adjacent baffles 12 and the spool 13 located between them can be adapted to carrier tapes of different specifications.
[0057] In one implementation, please refer to the following: Figure 4 and Figure 5 The drum 13 is formed by multiple arc-shaped pieces 131, with a gap 131A between adjacent arc-shaped pieces 131. This structure allows one end of the carrier tape to be inserted into the drum 13 through the gap 131A between adjacent arc-shaped pieces 131 and secured between them during winding, thus fixing the end of the carrier tape to the drum 13 and preventing it from shifting during winding, thereby improving the convenience of the winding operation.
[0058] In one implementation, please refer to the following: Figure 4 and Figure 5 There are four arc-shaped pieces 131, each of which is a quarter arc-shaped piece 131. In this way, the four quarter arc-shaped pieces 131 can be combined to form a circular drum 13 and four gaps 131A, and the four gaps 131A are arranged at equal intervals along the circumference of the drum 13, so that the end of the carrier tape can be fixed to the drum 13 using any gap 131A.
[0059] Please refer to the preferred options as well. Figure 4 and Figure 5The dimension H3 of the arc-shaped piece 131 in the axial direction of the baffle 12 is greater than the width of the carrier belt. The difference between the dimension H3 of the arc-shaped piece 131 in the axial direction A1 of the roll 11 and the width of the carrier belt is in the range of 1mm to 2mm (including the endpoint value). For example, this difference can be any value among 1mm, 1.5mm, and 2mm. In this way, the dimension H3 of the roll 13 in the axial direction of the baffle 12 is greater than the width of the carrier belt, and the difference between the dimension H3 of the arc-shaped piece 131 in the axial direction A1 of the roll 11 and the width of the carrier belt is set to be in the range of 1mm to 2mm. This makes the difference between the dimension H3 of the roll 13 in the axial direction of the baffle 12 and the width of the carrier belt not significant. This not only makes it convenient to use the roll 13 to wind up the carrier belt, but also allows the roll 13 to limit the displacement of the carrier belt on its axis A1, avoiding large displacement of the carrier belt in the axial direction A1 of the roll 13.
[0060] Please refer to the preferred options as well. Figure 4 and Figure 5 The thickness T of the arc-shaped piece 131 ranges from 1 mm to 1.7 mm (including the endpoints). For example, the thickness T of the arc-shaped piece 131 can be any value among 1 mm, 1.5 mm, and 1.7 mm.
[0061] Please refer to the preferred options as well. Figure 4 and Figure 5 The dimension S3 of the gap 131A in the circumferential direction of the drum 13 ranges from 3mm to 5mm (including the endpoint value). For example, the dimension S3 of the gap 131A in the circumferential direction of the drum 13 can be any value among 3mm, 4mm, and 5mm. In this way, the dimension S3 of the gap 131A in the circumferential direction of the drum 13 can be adapted to the thickness of the carrier tape so that the end of the carrier tape passes through the gap 131A and is clamped between the two adjacent arc plates 131.
[0062] Please refer to the preferred options as well. Figure 4 and Figure 5 The outer diameter D3 of the drum 13 ranges from 55mm to 85mm (including the end values). For example, the outer diameter of the drum 13 can be any value among 55mm, 65mm, 75mm, and 85mm. In this way, the outer diameter D3 of the drum 13 can be adapted to carrier tapes of different lengths.
