Description

Technical Field

[0001] This application relates to the technical field of electronic components, and in particular to an electronic component carrier reel spool. Background Technology

[0002] A carrier tape reel is a winding device consisting of two circles and a shaft, and it is a crucial step in the manufacturing process of some electronic components.

[0003] A utility model patent with Chinese patent authorization announcement number CN discloses an electronic component carrier reel shaft, comprising a first carrier reel and a second carrier reel. The key feature is that a first shaft is fixedly installed at the inner center of the first carrier reel, and a second shaft is fixedly installed at the inner center of the second carrier reel. A corrugated tube is detachably installed on the outer wall of the second shaft. This electronic component carrier reel shaft features a limiting groove formed on the outer wall of a first metal block, with a lightweight spring fixedly installed inside the groove. A second metal block is fixedly sleeved inside the lightweight spring. A limiting block is connected through the center of the outer surface of the second shaft. This design solves the problem of accommodating electronic components of various sizes when using carrier reels. The detachable corrugated tube on the outer wall of the second shaft prevents damage to electronic components caused by mutual compression during use.

[0004] The solution also has the following problems: The device adjusts the distance between the first and second carrier reels by adjusting the distance between the threaded rod and the second hole, so that the length of the carrier reel can be adjusted to suit various sizes of electronic component packaging solutions. However, the above solution still has some problems. For example, the connection between the reel shaft and the second carrier reel is a fixed connection, which means that the carrier reel and the reel shaft form an inseparable whole. Even if only the carrier reel is partially worn, the reel shaft and the carrier reel must be scrapped and replaced as a whole, rather than replacing the damaged parts separately. Therefore, when the carrier reel has wear, deformation or other faults, it is not possible to quickly disassemble and install the reel shaft and the second carrier reel, which may lead to further spread of the fault, triggering chain damage and shortening the overall life of the equipment.

[0005] Therefore, in order to solve the above problems, this application provides an electronic component carrier tape reel spool. Utility Model Content

[0006] To address the problem that the disassembly process of the threaded rod adjustment structure is cumbersome when the carrier reel or reel shaft experiences wear, deformation, or other malfunctions, thus preventing quick disassembly and installation between carrier reel one and reel shaft and carrier reel two, this application provides a carrier reel shaft for electronic components.

[0007] This application provides an electronic component carrier tape reel shaft, comprising a carrier tape reel one and a shaft. The shaft is fixedly connected to one side of the carrier tape reel one, and a second carrier tape reel is disposed on one side of the shaft. A locking device is provided on one side of both the second carrier tape reel and the shaft. The locking device includes: The carrier reel has four through-holes on one side near the reel shaft. Each of the mounting slots has a snap-fit ​​plate fixedly installed in it. Each of the snap-fit ​​plates has a through-hole hinge slot on one side. Each of the hinge slots has a rotating shaft rotatably connected to it. Two arc-shaped plates are hinged to the rotating shaft. Four mounting plates are fixedly connected to one side of the reel shaft. Each of the mounting plates has a snap-fit ​​plate fixedly connected to the side near the arc-shaped plate. Each snap-fit ​​plate is adapted to the two arc-shaped plates. A limit device is provided on the disc shaft; A drive assembly is provided on the disc shaft.

[0008] Preferably, both sides of the two arc-shaped plates are fixedly connected to connecting plates, and elastic elements are fixedly connected between the two connecting plates and the snap-fit ​​plate.

[0009] Preferably, the middle part of the first carrier reel, the second carrier reel, and the reel shaft is hollow, and an annular flange is added to the middle part of the first carrier reel, the second carrier reel, and the reel shaft.

[0010] Preferably, the limiting device includes: The top and bottom of the disc shaft are both provided with sliding grooves, and sliders are slidably installed in both of the two sliding grooves. A limit ring is fixedly connected between the two sliders, and the inner side of the limit ring is adapted to the outer side of the disc shaft.

[0011] Preferably, the limiting ring is made of rubber.

[0012] Preferably, one side wall of each of the two grooves is fixedly connected to one side of the slider with a folding plate.

[0013] Preferably, the driving component includes: A screw is rotatably installed in the upper slide groove. The screw passes through one of the sliders and the carrier tape reel. The screw is threadedly connected to one of the sliders and the carrier tape reel. A limit rod is fixedly connected in the lower slide groove. The limit rod passes through another slider and slides with the other slider.

[0014] Preferably, a fixing plate is fixedly connected to one end of the screw, and a handle is fixedly connected to the top of the fixing plate.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, a clamping plate is inserted between two opposing arc-shaped plates. Simultaneously, the force of the clamping plate causes the two arc-shaped plates to move to both sides via a rotating shaft, exposing a gap. The clamping plate is then inserted into this gap. The two arc-shaped plates are then reset by the force of the connecting plate and the elastic element, resulting in the clamping plate being tightly wrapped by the two arc-shaped plates. This wrapping fixing method provides extremely strong connection stability, avoiding problems such as carrier reel shaking or shifting. It quickly connects the reel shaft and the carrier reel together, enabling tool-free and rapid installation of the reel shaft and carrier reel. This saves a significant amount of time, shortens the time required to replace the carrier reel, significantly improves installation efficiency, reduces maintenance costs, and prevents reel falls caused by accidental omission of screws, thus increasing safety.

[0016] 2. In this utility model, a screw is used to rotate, which drives one of the sliders to move. This slider drives a limiting ring to move, which in turn drives another slider to move. The other slider slides on the limiting ring, thereby allowing the limiting ring to move left and right on the disc shaft. This provides a limit for different widths of carrier belts. This structure can be adjusted to cover various carrier belt widths, eliminating the need for dedicated limiting components or disc shaft replacements for different widths of carrier belts. This significantly improves the versatility of the disc shaft and reduces the complexity of equipment maintenance. Attached Figure Description

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1, as Figure 1-4 As shown, this utility model provides an electronic component carrier tape reel shaft, including a carrier tape reel 1, a reel shaft 3, a locking device, a limiting device, and a drive assembly; the reel shaft 3 is fixedly connected to one side of the carrier tape reel 1, and a carrier tape reel 4 is provided on one side of the reel shaft 3. The locking device includes: four mounting slots are provided through the side of the carrier tape reel 4 near the reel shaft 3, and locking plates 7 are fixedly installed in each of the mounting slots; a hinge slot is provided through the side of each of the locking plates 7, and a rotating shaft 11 is rotatably connected to each of the hinge slots; two hinges are hinged on the rotating shaft 11. Four mounting plates 9 are fixedly connected to one side of the arc plate 10 and the disc shaft 3. Each mounting plate 9 is fixedly connected to a clamping plate 6 on the side near the arc plate 10. Each clamping plate 6 is adapted to two arc plates 10. Each side of the two arc plates 10 is fixedly connected to a connecting plate 13. An elastic element 12 is fixedly connected between the two connecting plates 13 and the clamping plate 7. The middle of the carrier tape reel 1, the carrier tape reel 2, and the disc shaft 3 is hollow. An annular flange 8 is added to the middle of the carrier tape reel 1, the carrier tape reel 2, and the disc shaft 3 to restrict the movement of the carrier tape 1 and the carrier tape 2. The limiting device includes: a sliding groove is provided through the top and bottom of the disc shaft 3, and a slider 15 is slidably installed in each of the two sliding grooves. A limiting ring 2 is fixedly connected between the two sliders 15. The inner side of the limiting ring 2 is adapted to the outer side of the disc shaft 3. A folding plate 5 is fixedly connected to one side of each of the two sliding grooves and one side of the slider 15 to prevent dust from falling in.

[0022] In this embodiment, when installation is required, the four clamping plates 6 on the disc shaft 3 are aligned with the four mounting slots on the carrier tape reel 4, and then the four clamping plates 6 are pushed into the mounting slots. The four clamping plates 6 are inserted between two opposing arc-shaped plates 10. At the same time, the force of the clamping plates 6 causes the two arc-shaped plates 10 to move to both sides through the rotating shaft 11, exposing the gap, and the clamping plates 6 are inserted into it. Then, the two arc-shaped plates 10 are reset by the force of the connecting plate 13 and the elastic element 12, so that the clamping plates 6 are tightly wrapped by the two arc-shaped plates 10, and the disc shaft 3 and the carrier tape reel 4 are quickly installed together. When winding the carrier tape, the sliding limiting ring 2 is slidable. The limiting ring 2 drives the two internal sliders 15 to move, so that the limiting ring 2 can limit and fix the carrier tape according to the width of the carrier tape.

[0023] Example 2, as Figure 1-4As shown, the drive assembly includes: a screw 14 rotatably mounted in the upper groove, the screw 14 passing through one of the sliders 15 and the carrier reel 1, the screw 14 being threadedly connected to one of the sliders 15 and the carrier reel 1; a limit rod 18 fixedly connected in the lower groove, the limit rod 18 passing through another slider 15, the limit rod 18 slidingly engaging with the other slider 15; a fixing plate 17 fixedly connected to one end of the screw 14, and a handle 16 fixedly connected to the top of the fixing plate 17; the threads between the screw 14, the slider 15, and the carrier reel 1 can achieve self-locking. The thread self-locking condition depends on the helix angle, the coefficient of friction, and the load applied. The thread self-locking condition can be calculated using the following formula: self-locking condition = coefficient of friction × tan(helix angle) ≥ 1. When this condition is met, the threaded connection is self-locking. The above content is all prior art; however, in practical applications, the corresponding self-locking angle can be set according to the friction coefficient of the material, which will not be elaborated further here.

[0024] In this embodiment, the handle 16 is gripped and rotated, which causes the connecting plate 13 to rotate. The connecting plate 13 then causes the screw 14 to rotate, which in turn causes one of the sliders 15 to move. This slider 15 then causes the limiting ring 2 to move, which in turn causes the other slider 15 to move. The other slider 15 slides on the limiting ring 2, thereby allowing the limiting ring 2 to move left and right on the disc shaft 3, thus limiting the width of the carrier belt.

[0025] Working principle: In use, align the four clamping plates 6 on the disc shaft 3 with the four mounting slots on the carrier reel 4, then push the four clamping plates 6 into the mounting slots. The four clamping plates 6 are engaged between two opposing arc-shaped plates 10. At the same time, the resistance of the clamping plates 6 causes the two arc-shaped plates 10 to move to both sides via the rotating shaft 11, exposing a gap and engaging the clamping plates 6. Then, the two arc-shaped plates 10 are reset by the force of the connecting plate 13 and the elastic element 12, so that the clamping plates 6 are tightly wrapped by the two arc-shaped plates 10, quickly connecting the disc shaft 3 and the carrier reel 4. When quickly assembled and the carrier tape is wound, the handle 16 can be gripped and rotated. The handle 16 drives the connecting plate 13 to rotate, the connecting plate 13 drives the screw 14 to rotate, the screw 14 rotates and drives one of the sliders 15 to move. One of the sliders 15 drives the limiting ring 2 to move, the limiting ring 2 drives the other slider 15 to move, and the other slider 15 slides on the limiting ring 2, so that the two sliders 15 drive the limiting ring 2 to move, thereby allowing the limiting ring 2 to limit and fix the carrier tape according to the width of the carrier tape.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
