Description

Technical Field

[0001] This utility model belongs to the field of reel changing technology, and specifically relates to a reel changing device. Background Technology

[0002] A reel is a tray that carries carrier tape for surface mount capacitors. It primarily winds pre-reeled capacitor carrier tape in a specific quantity and length to meet the user's machine requirements. A reel changer is a tool for changing reels, mainly using replacement discs at both ends to transfer the required carrier tape onto a new reel. Currently, finished reel changers on the market are single-reel changers, which are inefficient and affect delivery. Therefore, it is necessary to provide a reel changer device that can improve changing efficiency and solve the aforementioned technical problems. Utility Model Content

[0003] To overcome the aforementioned shortcomings, the inventors of this utility model, through long-term exploration, experimentation, and continuous innovation, have proposed a reel-changing device. This device is driven by a crank handle, allowing for manual reel winding and flexible adjustment. The lengths of the unwinding and rewinding shafts have been increased to enable simultaneous reel changing of up to 10 reels. The reels are installed vertically, utilizing gravity and a central guide rod to prevent the carrier tape from tangling. The key control point is the central guide rod, under which the carrier tape passes, ensuring the adhesive surface is aligned with the bottom of the guide rod. During movement, a downward force is applied to the adhesive surface, preventing it from peeling off. Simultaneously, a wave-shaped buffer force is provided to the carrier tape, ensuring smooth, unbent operation and maintaining the quality of reel changing.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A reel changing device is provided. It includes a mounting frame, with mounting seats at both ends of the upper part of the mounting frame. An unwinding shaft and a rewinding shaft are respectively mounted on the two mounting seats. The length of the unwinding shaft and the rewinding shaft is greater than the thickness of a 10-reel reel. The reel is mounted on the unwinding shaft and the rewinding shaft. An intermediate guide rod is provided between the unwinding shaft and the rewinding shaft, and a crank handle is provided on the rewinding shaft.

[0005] A further preferred embodiment of the reel changing device according to the present invention is: the upper part of the mounting frame has a protruding crossbeam, and mounting seats are provided on the upper surface of the protruding portions at both ends of the crossbeam.

[0006] A further preferred embodiment of the reel changing device according to the present invention is that the intermediate guide rod is located in the middle of the crossbeam.

[0007] A further preferred embodiment of the reel changing device according to the present invention is as follows: the carrier tape passes under the middle guide rod, with the adhesive surface of the carrier tape facing downward at the bottom of the guide rod, so that a downward force is applied to the adhesive surface during the movement to ensure that the adhesive surface does not come off.

[0008] A further preferred embodiment of the reel changing device according to the present invention is that the length of the intermediate guide rod is greater than the lengths of the unwinding shaft and the rewinding shaft.

[0009] A further preferred embodiment of the reel changing device according to the present invention is that a crank handle is also provided on the unwinding shaft.

[0010] A further preferred embodiment of the reel changing device according to the present invention is that both the unwinding shaft and the rewinding shaft are provided with retaining strips, which correspond to the notches on the reel to prevent the reel from rotating.

[0011] A further preferred embodiment of the reel changing device according to the present invention is as follows: the mounting base includes a gasket, a bearing, and an arc-shaped clamping plate. The gasket is installed on the upper surface of the crossbeam, and the bearing is fixed between the gasket and the arc-shaped clamping plate. The unwinding shaft and the rewinding shaft are both rotatably installed by passing through the bearing.

[0012] Compared with the prior art, the technical solution of this utility model has the following advantages / benefits:

[0013] 1. It adopts a crank-driven, manual winding mechanism, which allows for flexible adjustment. The length of the unwinding and rewinding shafts is extended, enabling simultaneous reel changing for up to 10 reels. The reels are installed vertically, and gravity and the central guide rod work together to prevent the carrier tape from tangling.

[0014] 2. The key control point is the central guide rod. The carrier tape passes under the guide rod, ensuring that the adhesive surface of the carrier tape is oriented at the bottom of the guide rod. During movement, this provides a downward force to the adhesive surface, preventing it from coming unglued. It also provides a wave-like buffer force to the carrier tape, ensuring smooth operation without buckling or affecting the quality of reel changes. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the detailed description of the embodiments of this utility model provided below is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model.

[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

[0021] Example:

[0022] like Figure 1 As shown, a reel changing device includes a mounting frame 1, with mounting seats 2 at both ends of the upper part of the mounting frame 1. An unwinding shaft 3 and a rewinding shaft 4 are respectively mounted on the two mounting seats 2. The length of the unwinding shaft 3 and the rewinding shaft 4 is greater than the thickness of a 10-reel reel 8. The reel 8 is mounted on the unwinding shaft 3 and the rewinding shaft 4. An intermediate guide rod 6 is provided between the unwinding shaft 3 and the rewinding shaft 4. A crank handle 7 is provided on the rewinding shaft 4 for manual rotation to rewind the reel. The unwinding shaft 3 and the rewinding shaft 4 are relative concepts; if one is the unwinding shaft 3, the other is the rewinding shaft 4.

[0023] The mounting frame 1 has an extended crossbeam 101 on its upper part. Mounting seats 2 are provided on the upper surface of the extended portions at both ends of the crossbeam 101. The lower part of the mounting frame 1 is a supporting structure, specifically an I-shaped base with two columns. The crossbeam 101 is located on the two columns, and the two ends of the crossbeam 101 extend beyond the columns to form extended portions. The mounting seats 2 are installed on the extended portions to prevent interference when the crank 7 is rotated.

[0024] The intermediate guide rod 6 is located in the middle of the crossbeam 101. It is a crucial control point, with the carrier belt 9 passing underneath it. This ensures the adhesive surface of the carrier belt 9 is aligned with the bottom of the guide rod, providing a downward force to the adhesive surface during movement and preventing it from coming unglued. Simultaneously, it provides a wave-like buffer force to the carrier belt 9, ensuring smooth operation without buckling and maintaining the quality of reel changes. The wave-like buffer force refers to the relatively gentle, wave-like structure formed by the entire extended portion of the carrier belt 9.

[0025] The carrier tape 9 passes under the middle guide rod 6, with the adhesive surface of the carrier tape 9 facing down at the bottom of the guide rod. During the movement, a downward force is applied to the adhesive surface to ensure that the adhesive surface does not come off, that is, a certain pressure is formed to ensure that the adhesive layer on the carrier tape 9 does not detach.

[0026] The length of the intermediate guide rod 6 is greater than the lengths of the unwinding shaft 3 and the rewinding shaft 4, ensuring that the carrier tape 9 will not detach from the intermediate guide rod 6 during the winding process.

[0027] The unwinding shaft 3 is also equipped with a crank handle 7, which can be used to adjust tightening, reverse winding, and other operations.

[0028] Both the unwinding shaft 3 and the rewinding shaft 4 are provided with retaining strips 5. The retaining strips 5 correspond to the notches on the reel 8 to prevent the reel from rotating. The retaining strip 5 is actually a protruding part that corresponds to the notch in the hole on the reel to prevent the reel from rotating on the shaft. In this utility model, square retaining strips 5 are used.

[0029] The mounting base 2 includes a gasket 201, a bearing 202, and an arc-shaped clamping plate 203. The gasket 201 is installed on the upper surface of the crossbeam 101, and the bearing 202 is fixed between the gasket 201 and the arc-shaped clamping plate 203. The unwinding shaft 3 and the winding shaft 4 are both rotatably installed by passing through the bearing 202. The main purpose of the mounting base 2 is to rotatably install the unwinding shaft 3 and the winding shaft 4. Therefore, any reasonable structure can be used without strict restrictions.

[0030] Working Principle: This device can hold 10 reels at each of its two loading ends. The loading rod is designed with locking strips to position the reels and prevent them from shifting. The carrier tape interface on each reel is manually connected to the new reel, and the crank is manually turned to rotate it. The key control point is the central guide rod. The carrier tape passes under the guide rod, ensuring the adhesive surface is aligned with the bottom of the guide rod. During movement, a downward force is applied to the adhesive surface to prevent it from peeling off. Simultaneously, a wave-like buffer force is applied to the carrier tape, ensuring smooth, unbent operation and preserving the quality of reel changes.
