Description

Technical Field

[0001] The utility model relates to the technical field of carrier tape winding, in particular to a carrier tape reel. Background Art

[0002] During the packaging, transportation and storage of chip electronic components such as semiconductors, capacitors, and resistors, carrier tapes are often required. The carrier tape is made by cutting a carrier tape sheet into strips and forming receiving holes for receiving electronic components and indexing holes for traction at equal intervals on the strips. After being made, the carrier tape is stored and transported by winding around a reel.

[0003] The existing reel consists of a cylindrical core and baffles fixed on both sides of the core. The core is used for winding the carrier tape, and the baffles are used to prevent the carrier tape from winding deviation and loosening. After the carrier tape is wound around the reel to form a carrier tape reel, multiple carrier tape reels are placed side by side in a carton for subsequent storage and transportation processes. However, during the storage and transportation process, the baffles are easily squeezed and deformed, affecting the quality of the carrier tape. In addition, during the process of taking out the carrier tape reel, since there is no gap between the side-by-side carrier tape reels, it is difficult to take out, and the carrier tape will also be squeezed and deformed during the taking-out process.

[0004] To solve the above problems, the patent with the application number JP2005298053 discloses a reel for taping, including a core for winding a carrier tape loaded with multiple electronic components and a cover plate for supporting the core. The cover plate includes baffle 1 and baffle 2, which can cover the wound carrier tape without gaps except for the opening for the carrier tape to pass through, preventing the baffle from being deformed by external pressure and damaging the electronic components in the carrier tape, and preventing dust and the like from entering the inside of the reel and adhering to the electronic components. However, when winding the carrier tape on the above reel, the carrier tape enters from the opening, and the rest is a fully enclosed structure, so it is impossible to directly observe the state of the wound carrier tape and determine the winding quality of the carrier tape. Summary of the Utility Model

[0005] To solve the above problems, the utility model provides a carrier tape reel, which can ensure that the carrier tape is not squeezed and deformed while facilitating the staff to observe the winding state of the carrier tape.

[0006] The technical solution of the utility model to solve the above problems is as follows:

[0007] A carrier tape reel includes a drum and two circular baffles arranged at both ends of the drum. A winding area for winding the carrier tape is formed between the outer periphery of the drum and the two baffles, and a detachable protective cover is covered in the winding area.

[0008] The carrier tape is reciprocally wound around the outer periphery of the reel. The baffle can limit the carrier tape to prevent winding deviation of the carrier tape and looseness on the side after winding. The protective cover is wrapped outside the carrier tape to fully support the baffle and prevent the baffle from being squeezed and deformed. At the same time, the detachable installation method of the protective cover also facilitates observing the winding state of the carrier tape in the winding area.

[0009] Preferably, the baffle is made of paper material.

[0010] Preferably, the protective cover includes a plurality of protective units with the same structure that are connected end to end in sequence. The adjacent joints between the protective units can all be regarded as a reinforcing rib.

[0011] Preferably, the thickness of the protective cover is 0.4 - 0.5 mm.

[0012] Since the adjacent joints between the protective units can all be regarded as a reinforcing rib, the strength of the protective cover with a thickness of 0.4 - 0.5 mm is equivalent to that of an annular protective cover with a thickness of more than 1 mm. While saving costs, the protective cover can fully support the baffle and prevent the baffle from being squeezed and deformed.

[0013] Preferably, the width of the protective cover is 2 - 3 mm smaller than the distance between the two baffles. This can ensure that the protective cover can be embedded between the two baffles and provide effective supporting force.

[0014] Preferably, the outer perimeter of the radial cross-section of the protective cover is 110 - 140 mm smaller than the outer perimeter of the baffle.

[0015] During the storage and transportation of the carrier tape, the carrier tape may expand and contract due to heat. This setting method can reserve sufficient expansion space for the carrier tape while ensuring the supporting effect of the protective cover on the baffle.

[0016] The shape of the protective unit is not limited and can be a rhombus, triangle, parallelogram, rectangle, etc., and preferably a rectangle.

[0017] Because the adjacent joints between the protective units can all be regarded as a reinforcing rib, when the protective unit is a rectangle, the reinforcing rib is in the same direction as the supporting force on the baffle to achieve the optimal supporting effect.

[0018] Preferably, the side length of the adjacent side of the protective unit and the baffle is 80 - 100 mm. This makes the number of protective units and reinforcing ribs forming the protective cover relatively large, thereby increasing the strength of the protective cover.

[0019] Preferably, the detachable protective cover is formed by connecting the head and tail of a strip material to achieve the detachable installation of the protective cover.

[0020] Preferably, the material of the protective cover is selected from at least one of PC, PS, ABS, and PET.

[0021] Preferably, the material of the protective cover is the same as that of the carrier tape. Since the two materials are the same, the protective cover can be made of the recycled edge materials in the carrier tape manufacturing process.

[0022] Preferably, a protective film wound between the reel and the protective cover is further included in the winding area.

[0023] Preferably, the number of winding turns of the protective film is 1.5 - 2.0 turns.

[0024] The protective film is wound around the wound carrier tape. The setting of the protective film can prevent foreign matters such as dust from contacting the carrier tape, and at the same time prevent the carrier tape from loosening; in addition, the soft protective film can prevent the carrier tape from directly contacting the protective cover and avoid scratching the carrier tape by the protective cover.

[0025] Preferably, an observation hole for observing the winding state of the carrier tape is provided on the baffle. The setting of the observation hole makes it more convenient for the staff to observe the winding state of the carrier tape.

[0026] Preferably, a handle is provided between the two baffles, and both ends of the handle are respectively connected to the two baffles.

[0027] Preferably, the handle is made of fiber tape. Both ends of the fiber tape are pasted on the two baffles to form the handle, which is convenient for taking and placing the carrier tape reel, and the number of handles is not limited.

[0028] The utility model has the following beneficial effects:

[0029] The carrier tape reel of the utility model includes a reel and baffles arranged at both ends of the reel. After the carrier tape is wound, a detachable protective cover is covered on the outer periphery of the carrier tape. The protective cover can fully support the baffles, prevent the baffles from being squeezed and deformed, thereby ensuring the quality of the carrier tape. At the same time, the detachable covering method of the protective cover can facilitate the staff to observe the winding state of the carrier tape and determine the winding quality of the carrier tape.

[0033] In order to make the purpose, technical solutions and advantages of the utility model more clear, the present utility model will be further described in detail in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the protection scope of the present utility model.

[0034] A carrier tape reel, as Figure 1 and Figure 2 shown, includes a reel 2 and two circular baffles 3 disposed at both ends of the reel 2. A winding area for winding the carrier tape 1 is formed between the outer periphery of the reel 2 and the two baffles 3, that is, the carrier tape 1 can be wound around the reel 2 and located between the two baffles 3. The two baffles 3 can limit the carrier tape 1, thereby avoiding problems such as deviation in winding of the carrier tape 1 and looseness of the side surface after winding, which may cause the carrier tape 1 to be unusable. The baffle 3 and the reel 2 can be fixedly connected or detachably connected. In this embodiment, the reel 2 and the baffle 3 are fixedly connected. The baffle 3 is made of a paper material, which can save the manufacturing cost of the carrier tape reel while realizing the limiting function. An observation hole 31 is provided on the baffle 3 to assist in observing the winding state of the carrier tape 1 in the winding area. The number of observation holes 31 is not limited. In this embodiment, two observation holes 31 are provided on each baffle 3.

[0035] A protective cover 4 is also provided in the winding area. After the carrier tape 1 is wound, the protective cover 4 can be detachably wrapped around the outer periphery of the carrier tape 1 to support the two baffles 3 and prevent the baffles 3 from being squeezed and deformed, thereby ensuring the quality of the carrier tape 1. The material of the protective cover 4 can be PC, PS, ABS, PET, etc. In this embodiment, the material of the protective cover 4 is the same as that of the carrier tape 1, so the protective cover 4 can be made of the recycled edge material in the manufacturing process of the carrier tape 1.

[0036] The thickness of the protective cover 4 is 0.4 - 0.5 mm. It includes a plurality of protective units with the same shape and size. The plurality of protective units are connected end to end in sequence to form a strip. The strip surrounds the outer periphery of the carrier tape 1 and is joined to form the protective cover 4. The adjacent joints between the protective units can all be regarded as a reinforcing rib. When joined, natural overlapping areas will be generated at both ends of the strip. The length of the overlapping area at the joint is 90 - 100 mm, thereby realizing the detachable installation of the protective cover 4.

[0037] The shape of the protection unit is not limited and can be a rhombus, triangle, parallelogram, rectangle, etc. In this embodiment, the protection unit is rectangular. The adjacent joints of adjacent protection units can all be regarded as a reinforcing rib. Therefore, the strength of the protective cover 4 is equivalent to that of a traditional annular protective cover with a thickness of more than 1 mm, which can sufficiently support the baffle 3, prevent the baffle 3 from being squeezed and deformed, and at the same time, the reduction of the thickness also saves the manufacturing cost of the carrier tape reel.

[0038] The width of the protective cover 4 needs to be 2 - 3 mm smaller than the distance between the two baffles 3 to ensure that the protective cover 4 can be embedded between the two baffles 3 and effectively provide a supporting force. The side length of the protection unit adjacent to the baffle 3 is 80 - 100 mm, so that the number of protection units and reinforcing ribs forming the protective cover 4 is relatively large, achieving an excellent strength enhancement effect and further improving the supporting effect of the protective cover 4 on the baffle 3.

[0039] In addition, the outer perimeter of the radial cross-section of the protective cover 4 is 110 - 140 mm smaller than the outer perimeter of the baffle 3. This is because during the storage and transportation of the carrier tape reel, such as during warehouse storage or container sea transportation, the carrier tape 1 will expand and contract due to temperature changes. Therefore, to avoid the deformation of the carrier tape 1 caused by the carrier tape 1 exceeding the diameter of the baffle 3 in extreme cases, an expansion space needs to be reserved for the carrier tape 1. When the protective cover 4 is not provided, usually, the maximum diameter of the wound carrier tape 1 needs to be smaller than the diameter of the baffle 3, and the difference between the two is 40 mm. The above-mentioned perimeter difference is consistent with this, and there is also an overlapping connection area with a length of 90 - 100 mm at both ends of the strip forming the protective cover 4, indicating that while the protective cover 4 supports the baffle 3, it also provides sufficient space for the expansion of the carrier tape 1.

[0040] The carrier tape reel further includes a protective film 5. The protective film 5 is arranged in the winding area. After the carrier tape 1 is wound, the protective film 5 is arranged between the carrier tape 1 and the protective cover 4. The protective film 5 wraps around the outer peripheral surface of the carrier tape 1 for 1.5 - 2.0 turns to prevent foreign objects or dust from contacting the carrier tape 1, maintain the cleanliness of the carrier tape 1, and at the same time prevent the carrier tape 1 from loosening. And compared with the protective cover 4, the protective film 5 is softer. Blocking a protective film 5 between the protective cover 4 and the carrier tape 1 can also avoid the risk of the protective cover 4 scratching the carrier tape 1.

[0041] The carrier tape reel further includes a handle 6. Both ends of the handle 6 are respectively connected to the two baffles 3 to facilitate the picking up and placing of the carrier tape reel. The handle 6 can be made by pasting a fiber tape between the two side baffles 3. When the carrier tape reels placed side by side in a cardboard box are picked up, the presence of the handle 6 can greatly improve the operation convenience. The number of handles 6 is not limited. In this embodiment, the number of handles 6 is 4. The setting of multiple handles 6 makes the placement method of the carrier tape reel unrestricted and the picking up and placing more convenient.

[0042] For the carrier tape reel of the present utility model, after the carrier tape 1 is wound around the reel 2, a protective film 5 is wound around the outer periphery of the carrier tape 1, and a protective cover 4 is detachably covered around the outer periphery of the protective film 5, which can prevent the baffle 3 from being squeezed and deformed while observing the winding state of the carrier tape 1 to determine the winding quality of the carrier tape 1.
