Description

Technical Field

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

[0002] A carrier tape refers to a strip-shaped product applied in the field of electronic packaging. It has a specific thickness, and holes (also known as pockets) for placing electronic components and positioning holes for indexing and positioning are equidistantly distributed in its length direction;

[0003] During the production and processing of the carrier tape, it is necessary to wind and store the carrier tape for subsequent workers to easily take and use the carrier tape. However, the existing winding methods have the following deficiencies:

[0004] In the existing technology, since it is not convenient to lock and fix the open end of the carrier tape after winding and storing the carrier tape, and the open end of the carrier tape will be in a loose state, the carrier tape is prone to loosen and fall off even after being wound, resulting in poor winding stability of the overall carrier tape and reduced applicability;

[0005] In view of the above problems, the present utility model document proposes a limiting mechanism for a carrier tape reel. Summary of the Utility Model

[0006] The utility model provides a limiting mechanism for a carrier tape reel, which solves the deficiencies in the existing technology that it is not convenient to lock and fix the open end of the carrier tape after winding and storing the carrier tape, and the open end of the carrier tape will be in a loose state, so that the carrier tape is prone to loosen and fall off even after being wound, resulting in poor winding stability of the overall carrier tape and reduced applicability.

[0007] The utility model provides the following technical solutions:

[0008] A limiting mechanism for a carrier tape reel, comprising:

[0009] A reel, a rotation hole is formed inside the reel, a support rotating rod is rotatably connected to the inner wall of the rotation hole, and a hexagonal insertion block is fixedly arranged at one end of the support rotating rod for plugging and installing on a compatible winding rack;

[0010] A limiting mechanism, which is arranged on the support rotating rod for limiting and locking the reel;

[0011] A locking and clamping mechanism, which is arranged inside the reel for clamping and locking the carrier tape.

[0012] In a possible design, the limiting mechanism includes a threaded head, a limiting plate, a jack, three locking plug rods, a plurality of locking holes, and a threaded cap. The limiting plate is arranged on the outer wall of the supporting rotating rod. The jack is opened inside the limiting plate and is used to be inserted into the outer wall of the supporting rotating rod. The three locking plug rods are all fixedly arranged on one side of the limiting plate. The plurality of locking holes are respectively opened on both sides of the reel and are used for the locking plug rods to be inserted and locked.

[0013] In a possible design, the threaded head is fixedly arranged at one end of the supporting rotating rod away from the hexagonal insertion block. The threaded cap is threadedly connected to the outer wall of the threaded head and is used to limit and lock the limiting plate.

[0014] In a possible design, the locking and clamping mechanism includes a fixed frame, a fixed screw rod, two adjusting screw blocks, two anti-slip pads, a lifting screw rod, a knob, and a clamping plate. The fixed frame is arranged on the outer wall of the fixed screw rod. The fixed frame and the fixed screw rod are both arranged inside the reel. The two adjusting screw blocks are threadedly connected to the outer walls at both ends of the fixed screw rod. Each anti-slip pad is arranged on one side of the adjusting screw block and is used to closely fit to the inner wall of the reel.

[0015] In a possible design, the lifting screw rod is threadedly connected to the inner part of the top side of the fixed frame. The knob is fixedly arranged at the top end of the lifting screw rod. The clamping plate is rotatably connected to the bottom end of the lifting screw rod through a rotating shaft and is used to clamp and fix the open end of the carrier tape.

[0016] In a possible design, a plurality of rubber protrusions in contact with the carrier tape are arranged on the bottom side of the inner wall of the fixed frame and the bottom side of the clamping plate.

[0017] In a possible design, anti-slip lines are arranged on the outer walls of each of the adjusting screw blocks.

[0018] In this application, during use, first, the rotation hole of the reel is sleeved on the support rotating rod to ensure smooth rotation between the two. One end of the support rotating rod is fixed with a hexagonal insert block, which is used for plugging and installing on a compatible winding rack to fix the position of the support rotating rod, facilitating subsequent winding operations. The reel rotates on the support rotating rod, and then the carrier tape can be wound to achieve the effect of storage. When the winding of the carrier tape is completed, the limiting plate is inserted into the outer wall of the support rotating rod through the jack inside it, and at the same time, the three locking pins on the limiting plate are inserted into the corresponding locking holes to achieve preliminary fixation at the designated position. Then, the threaded head is fixed at one end of the support rotating rod away from the hexagonal insert block, and the threaded nut is threadedly connected to the outer wall of the threaded head. When it is necessary to lock the reel, rotate the threaded nut to move it downward along the threaded head, pushing the limiting plate and the locking pins closer to the reel, and then the limiting plate can be limited to achieve the effect of locking and fixing the reel, which is beneficial to preventing the reel from rotating again after winding, avoiding the rewinding of the carrier tape, and improving stability;

[0019] After the reel is limited and fixed, first place the fixing frame at the position corresponding to the open end of the carrier tape inside the reel, and then rotate the two adjusting screw blocks. By using the threaded connection of the adjusting screw blocks on the fixing screw rod, horizontal movement can be achieved, and then the distance between the two adjusting screw blocks can be adjusted, driving the anti-slip pads on one side of the adjusting screw blocks to closely fit the inner wall of the reel, which is beneficial to locking and installing the fixing frame inside the reel to facilitate the subsequent fixation of the open end of the carrier tape. Then, place the open end of the carrier tape inside the fixing frame, rotate the knob to move the lifting screw rod downward, and drive the clamping plate rotatably connected to the bottom end to descend. When the clamping plate descends to the appropriate position, the rubber protrusions on its bottom side are in close contact with the carrier tape, thereby achieving clamping and fixing to prevent the carrier tape from loosening and falling off, improving the firmness of storage. The rubber protrusions provided on the bottom side of the inner wall of the fixing frame and the bottom side of the clamping plate not only increase the anti-slip contact area with the carrier tape but also effectively prevent the carrier tape from being damaged during the clamping process through their softness and elasticity, improving applicability.

[0020] In this utility model, for the limiting mechanism of a carrier tape reel, the limiting mechanism can limit the limiting plate to achieve the effect of locking and fixing the reel, which is beneficial to preventing the reel from rotating again after winding, avoiding the rewinding of the carrier tape, and improving stability;

[0021] In this utility model, for the limiting mechanism of a carrier tape reel, the locking and clamping mechanism can adjust the distance between the two adjusting screw blocks, which is beneficial to locking and installing the fixing frame inside the reel, and at the same time realizes the clamping and fixing of the carrier tape, preventing the carrier tape from loosening and falling off, and improving the firmness of storage;

[0022] In the present utility model, after the carrier tape is wound and stored, it is convenient to lock and fix the open end of the carrier tape, preventing the open end of the carrier tape from being loose, avoiding the phenomenon that the carrier tape is prone to looseness and falling off after winding, being beneficial to enhancing the overall winding stability of the carrier tape, and improving the applicability.
