[0028] Example:

[0029] See also Figure 1-6A carrier tape reel comprises two baffles 1, which are symmetrically arranged. The ends of the two baffles 1 that are close to each other are fixedly connected with side reels 2, and a middle reel 3 is slidably connected between the two side reels 2. Insertion ports 9 are drilled on the two baffles 1, and a distance adjusting mechanism is arranged between the two baffles 1. The distance adjusting mechanism is used to adjust the distance between the two baffles 1 so as to realize the winding of carrier tapes of different widths.

[0030] In this embodiment, when winding up carrier tapes of different widths, the distance between the two baffles 1 is adjusted by a distance adjusting mechanism so that the two side reels 2 slide on the middle reel 3, thereby adjusting the width between the two side reels 2 and the middle reel 3, so that the two baffles 1 cooperate with the two side reels 2 and the middle reel 3 to be suitable for carrier tapes of different widths. The two baffles 1 are inserted into the rotating shaft of the winding device through two plug interfaces 9, and the two baffles 1, the two side reels 2 and the middle reel 3 are controlled to rotate through the rotating shaft to wind up the carrier tape.

[0031] Specifically, the distance adjustment mechanism includes a threaded rod 41, a stroke nut 42, an externally threaded tube 43, a rectangular slot 44, a rectangular plug rod 45 and an internally threaded tube 46. The threaded rod 41 is rotatably connected to a baffle 1, the stroke nut 42 is threadedly connected to the outer surface of the threaded rod 41, the externally threaded tube 43 is rotatably connected to the stroke nut 42, and the externally threaded tube 43 is located on the outer side of the threaded rod 41, the rectangular slot 44 is drilled at one end of the threaded rod 41, the rectangular plug rod 45 is fixedly connected to the externally threaded tube 43, and the rectangular plug rod 45 is slidably inserted in the rectangular slot 44, the internally threaded tube 46 is fixedly connected to another baffle 1, and the internally threaded tube 46 is threadedly connected to the outer surface of the externally threaded tube 43.

[0032] In this embodiment, the stroke nut 42 is driven to move by rotating the threaded rod 41 on one baffle 1, the stroke nut 42 drives the external threaded tube 43 to move, the external threaded tube 43 drives the internal threaded tube 46 to perform a primary movement, and the internal threaded tube 46 drives another baffle 1 to move. At the same time, during the rotation of the threaded rod 41, the external threaded tube 43 is rotated by the connection between the rectangular plug rod 45 and the rectangular slot 44, the external threaded tube 43 further controls the movement of the internal threaded tube 46, and realizes the secondary movement of the internal threaded tube 46. The internal threaded tube 46 causes the other baffle 1 to move twice, thereby realizing the adjustment of the distance between the two baffles 1.

[0033] Specifically, a slider group 5 is fixedly connected to the travel nut 42 , a fixed rod group 6 is fixedly connected to one baffle plate 1 , and the slider group 5 is slidably connected to the outer surface of the fixed rod group 6 .

[0034] In this embodiment, when the travel nut 42 moves, it drives the slider group 5 to slide on the fixed rod group 6, and the movement of the travel nut 42 is kept stable through the sliding connection between the slider group 5 and the fixed rod group 6.

[0035] Specifically, the adjacent ends of the two baffles 1 are fixedly connected with sleeves 7 , and the two sleeves 7 are plugged into each other and correspond to the two plug ports 9 respectively.

[0036] In this embodiment, the entire reel is inserted into the rotating shaft of the winding device through two plug-in interfaces 9 to rotate and wind the carrier tape. During the insertion process, two sleeves 7 are used to facilitate the correspondence between the rotating shaft and the two plug-in interfaces 9 to ensure the stability of the insertion of the rotating shaft.

[0037] Specifically, a positioning block 8 is fixedly connected to the outer surface of one side reel 2, and the positioning block 8 is cylindrical.

[0038] In this embodiment, the positioning block 8 corresponds to the positioning hole of the carrier tape, and the carrier tape can be easily rolled up by connecting the positioning hole with the positioning block 8 .

[0039] Working principle: When winding up carrier tapes of different widths, the stroke nut 42 is moved by rotating the threaded rod 41 on a baffle 1. At the same time, the threaded rod 41 rotates the external threaded tube 43 through the insertion between the rectangular slot 44 and the rectangular insertion rod 45. The stroke nut 42 drives the external threaded tube 43 to move during the movement. The rotation of the external threaded tube 43 drives the internal threaded tube 46 to move. The internal threaded tube 46 pushes another baffle 1 to move, and the spacing between the two baffles 1 is adjusted to make the two side reels 2 slide on the middle reel 3, thereby adjusting the width between the two side reels 2 and the middle reel 3, so that the two baffles 1 cooperate with the two side reels 2 and the middle reel 3 to be suitable for carrier tapes of different widths. The two adjusted baffles 1 are inserted into the rotating shaft of the winding device through two plug interfaces 9, and the winding device controls the two baffles 1, the two side reels 2 and the middle reel 3 to rotate through the rotating shaft to wind up the carrier tape.

[0040] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the utility model according to the technical solution and improved ideas of the utility model, which should be included in the protection scope of the utility model.
