Description

Technical Field

[0001] This application relates to the field of capacitor tape and reel machine technology, and in particular to a roll support for a capacitor tape and reel machine. Background Technology

[0002] Capacitor taping machines are indispensable key equipment in the electronics manufacturing industry. They are mainly used to tap and package electronic components such as capacitors according to predetermined rules to facilitate subsequent automated production, storage, and transportation. With the continuous growth in demand for electronic products and the increasing market requirements for production efficiency, the performance of capacitor taping machines and the optimization of their supporting components have become particularly important. As the core component in capacitor taping machines that supports and fixes the tape rolls, the structure design and performance of the tape roll holder directly affect the efficiency of tape roll installation and replacement, as well as the stability of the entire machine operation.

[0003] Currently, the most common roll support in the industry typically employs a central shaft-fixed structure. Specifically, this structure involves a rigid mounting shaft mounted on the base of the tape machine, with removable baffles on both sides to prevent axial movement of the roll during rotation. When changing rolls, operators must first remove the baffles on the outside of the mounting shaft to remove the used roll core from the shaft and load in the new roll. The baffles must then be reinstalled to secure the new roll.

[0004] However, in practical applications, the process of disassembling and installing the aforementioned "removable baffle" structure is quite cumbersome, increasing the labor intensity of operators and the material change time, resulting in prolonged equipment downtime and affecting overall production efficiency. Utility Model Content

[0005] To address the problems of cumbersome operation and low efficiency in the traditional roll-to-roll holder during roll-to-roll changes, this application provides a roll-to-roll holder for a capacitor tape and reel machine.

[0006] The technical solution provided in this application for a capacitor tape and reel machine's roll support is as follows: A coil support for a capacitor tape machine includes two rotatably connected columns, one of which has a mounting shaft for mounting the coil. The two columns are close together to limit the coil on the mounting shaft, and the two columns are far apart to form a clearance space for unloading the coil. The coil support also includes a locking mechanism for locking and unlocking the two columns.

[0007] By adopting the above technical solution, when it is necessary to change the roll material, operators no longer need to perform the cumbersome steps of disassembling and installing the outer baffle. They only need to release the locking mechanism from the two uprights, which will move the two uprights apart, thus creating a wide and unobstructed clearance space between them. This allows the roll material to be easily removed or loaded directly from this lateral space, greatly simplifying the operation process, minimizing the material changeover time, effectively reducing equipment downtime, and directly improving the overall efficiency of the production line. At the same time, by avoiding the frequent disassembly and installation of the baffle as in the traditional method, not only is the labor intensity of the operators reduced, but the entire material changeover process is also faster, more stable, and safer.

[0008] Optionally, the two columns include a fixed column and a rotating column; the fixed column is provided with a connection structure for connecting to external equipment, the mounting shaft is mounted on the fixed column, and the rotating column is rotatably connected to the fixed column.

[0009] By adopting the above technical solution, the two columns are divided into a fixed column and a rotatable column, and the mounting shaft is set on the fixed column. This ensures that the mounting shaft and the coiled material it carries remain stable when the rotating column is opened and closed, avoiding the risk of the coiled material shaking or falling off due to the rotation of the column. This provides a structural basis for fast and safe lateral material changing.

[0010] Optionally, the rotation axis of the rotating column is perpendicular to the axis of the mounting shaft, and the rotation path of the rotating column lies in the plane containing the rotating column and the fixed column.

[0011] By adopting the above technical solution, the rotation axis of the rotating column is set to be perpendicular to the axis of the mounting shaft, and its rotation path is restricted to the plane where the two columns are located. This realizes the side-opening and closing action, so that the rotating column only needs to rotate a very small angle to form a sufficiently wide clearance space on the side. Operators can easily pick up and put down the coiled material laterally, just like opening a door, which greatly improves the convenience and efficiency of material changing operation.

[0012] Optionally, the locking mechanism includes a rotating rod, one end of which is rotatably connected to the fixed column, and the other end of which is engaged with the rotating column.

[0013] By adopting the above technical solution, the operator can quickly complete the unlocking and locking by simply lifting and pressing the lever, saving time and effort, and effectively ensuring that the two columns can be firmly locked together in the working state.

[0014] Optionally, it also includes two magnets, respectively disposed on the fixed column and the rotating column, one of the magnets being rotatable about an axis to form an attractive state and a repulsive state with the other magnet.

[0015] By adopting the above technical solution, magnets are set on the fixed column and the rotating column, and one of the magnets is rotatable, so that it can switch between attraction and repulsion. The attraction state can help lock and ensure that the limit is stable; while the repulsion state can provide a pushing force at the moment of unlocking, assisting the rotating column to automatically open a small stroke, making the operation more effortless and smooth.

[0016] Optionally, one of the magnets is rotatably mounted on the rotating column about an axis, and the other magnet is fixed to the fixed column.

[0017] By adopting the above technical solution, the rotatable magnet is set on the rotating column, while the fixed magnet is set on the fixed column. This concentrates the operation knob on the moving part, which is ergonomic and allows the operator to directly complete the magnetic pole switching operation on this part when preparing to change materials, thus optimizing the user experience.

[0018] Optionally, the mounting shaft can be rotatably mounted on the fixed column around an axis, and the mounting shaft is provided with a positioning structure for rotating synchronously with the coil.

[0019] By adopting the above technical solution, the mounting shaft is set to be able to rotate around its own axis, and a positioning structure is added to ensure that the mounting shaft can rotate synchronously and smoothly with the roll material, thus achieving stable unwinding. This effectively avoids the problems of wear on the tape surface or excessive traction resistance caused by the mounting shaft being fixed, and ensures the stability of the production process.

[0020] Optionally, the fixing column is provided with a guide groove extending vertically, and the mounting shaft can rotate around the axis and one end can move vertically and be installed in the guide groove; The guide groove is provided with a support seat adapted to the bottom wall of the mounting shaft, and a first elastic reset member is provided between the support seat and the bottom wall of the guide groove; the guide groove is provided with a friction seat adapted to the top wall of the mounting shaft, and a second elastic reset member is provided between the friction seat and the top wall of the guide groove; the friction force between the support seat and the mounting shaft is less than the friction force between the friction seat and the mounting shaft.

[0021] By adopting the above technical solution, the friction between the mounting shaft and the friction seat can be automatically adjusted according to changes in the weight of the coil. As the coil is used up and its weight decreases, the mounting shaft moves upward, increasing the pressure between it and the friction seat, and thus increasing the friction. This automatically suppresses over-rotation and slack caused by inertia of the coil, effectively preventing the phenomenon of slack stripping.

[0022] Optionally, the contact area between the support and the mounting shaft is smaller than the contact area between the friction seat and the mounting shaft.

[0023] By adopting the above technical solution, and by specifically limiting the contact area between the support base and the mounting shaft to be smaller than the contact area between the friction base and the mounting shaft, the structure ensures that the friction force provided by the friction base always dominates regardless of the state of the rolled material, thus guaranteeing the reliability of the damping adjustment effect and enabling the automatic anti-slackening function to be stably realized.

[0024] Optionally, the support base is fitted with balls.

[0025] By adopting the above technical solution, the friction between the mounting shaft and the support can be reduced.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. This application, through the cooperation of two rotatingly connected columns and a locking mechanism, completely changes the traditional operating mode of requiring the removal of baffles to change materials in roll material supports. Operators only need to unlock the locking mechanism to quickly move the two columns apart, creating a wide lateral clearance space, allowing for direct and easy horizontal loading and unloading of roll materials. This greatly simplifies the operation process, significantly shortens material changeover time, effectively reduces equipment downtime, and improves overall production efficiency.

[0027] 2. This application utilizes a rotating movable magnet to create an attractive or repulsive state between it and a fixed magnet. In the attractive state, the magnetic force assists the mechanical structure to achieve a fast and stable locking; in the repulsive state, the generated repulsive force not only helps to quickly unlock the magnet but also automatically pushes open the rotating column in the initial stage, making the opening action more effortless and smooth, greatly optimizing the user experience and ease of operation.

[0028] 3. This application automatically adjusts the friction force by changing the pressure between the mounting shaft and the friction seat through the up-and-down movement of the mounting shaft within the guide groove. As the roll material is used up and the weight decreases, the friction force increases accordingly, effectively suppressing over-rotation and slack caused by inertia of the roll material, fundamentally preventing the occurrence of belt misalignment, and ensuring the stability of the unwinding process and the quality of the tape.

[0031] The following will be combined with the appendix Figure 1-6 The technical solutions in the embodiments of this application are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] Example 1: This application discloses a roll support for a capacitor tape and reel machine, such as... Figure 1 and Figure 2 As shown, the coil support mainly includes two columns 1, a mounting shaft 2, and a locking mechanism 3.

[0033] The two columns 1 include a fixed column 12 and a rotating column 13. The fixed column 12 serves as the mounting base for the entire support, and its bottom or side is provided with a connecting structure, such as mounting holes or flanges, to securely connect the entire support to the base or frame of the capacitor tape and reel machine, providing a stable foundation for the coil support. The mounting shaft 2 is used to carry the coil and is rotatably mounted on the fixed column 12 around its own axis, allowing the coil to be smoothly unwound under traction. To further ensure that the coil rotates synchronously with the mounting shaft 2 and avoids slippage, the mounting shaft 2 is also provided with a positioning structure, such as a keyway or protrusion, for engaging with the inner hole of the coil core.

[0034] The rotating column 13 is connected to the fixed column 12 by a rotating connection. Specifically, it can be connected by a hinge or a rotating shaft, and together with the fixed column 12, they form the two side limiting columns of the coil.

[0035] In an optional embodiment, the rotation axis of the rotating column 13 may be parallel to the axis of the mounting shaft 2. In this embodiment, the rotation axis of the rotating column 13 is perpendicular to the axis of the mounting shaft 2, and its rotation path is restricted to the plane formed by the rotating column 13 and the fixed column 12.

[0036] When it is necessary to change the roll material, the operator only needs to rotate the rotating column 13 outward by a small angle (e.g., 30 to 45 degrees, or even smaller), which creates a wide lateral clearance space 11 between the fixed column 12 and the rotating column 13. The operator can easily open the rotating column 13 like opening a door and directly pick up and place the roll material onto the mounting shaft 2 from the side, completely avoiding the cumbersome steps of disassembling bolts and baffles in the traditional structure. This greatly simplifies the operation process, shortens equipment downtime, and thus directly improves production efficiency.

[0037] To ensure that the fixed column 12 and the rotating column 13 can reliably approach and securely limit the coiled material during operation, and to allow for quick unlocking during material changes, the locking mechanism 3 is used to lock and unlock the fixed column 12 and the rotating column 13. In one specific embodiment, such as... Figure 3 As shown, the locking mechanism 3 includes a rotating rod 31. One end of the rotating rod 31 is rotatably connected to the fixed post 12 via a pin, and its free end is provided with a hook that can engage with a slot on the rotating post 13. When the rotating rod 31 rotates to the position where it engages with the rotating post 13, the fixed post 12 and the rotating post 13 are securely locked together; conversely, lifting the rotating rod 31 upwards will release the lock, making the operation very convenient.

[0038] In an alternative embodiment, magnets are respectively provided on the fixed column 12 and the rotating column 13. One magnet (e.g., the magnet mounted on the rotating column 13) is configured to rotate about its own axis (referred to as the movable magnet), and can be adjusted by the operator via an exposed knob 32, which is fixedly connected to the movable magnet and rotatably mounted on the rotating column 13. The other magnet is fixedly mounted on the fixed column 12 (referred to as the fixed magnet). In other embodiments, the fixed magnet may also be mounted on the rotating column 13, in which case the movable magnet is mounted on the fixed column 12.

[0039] When the movable magnet is rotated so that its opposite poles are opposite to those of the fixed magnet, they attract each other, thus achieving rapid automatic adsorption and assisting in the quick locking of the fixed column 12 and the rotating column 13. When it is necessary to change materials, the movable magnet is rotated so that its like poles are opposite to those of the fixed magnet, and they repel each other. This repulsive force not only helps to quickly unlock the magnet, but also assists in pushing the rotating column 13 open in the initial stage, making the opening action more effortless and smooth.

[0040] The implementation principle of the coil support of the capacitor tape machine in this embodiment is as follows: Under normal working conditions, the rotating column 13 and the fixed column 12 are closely close together. The mechanical latch of the rotating rod 31 and the attraction force of the opposite pole magnets work together to provide a stable axial limit for the coil. When it is necessary to change the coil, the mechanical latch is released and the knob 32 is rotated to make the magnets face each other. The resulting repulsive force will help the operator to easily push the rotating column 13 open, forming a wide lateral clearance space 11, which allows the coil to be directly picked up and put in laterally. The whole process does not require disassembling any parts, realizing fast, labor-saving and efficient operation.

[0041] Example 2: like Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that, in order to address the problem that the coil material may become loose or tangled due to inertia during the unwinding process, the coil material support also includes a damping adjustment structure. Specifically, the fixed column 12 has a guide groove 12a extending vertically, one end of the mounting shaft 2 is installed in this guide groove 12a and can slide within the guide groove 12a, and the mounting shaft 2 can both rotate and move vertically within the guide groove 12a.

[0042] like Figure 5 and Figure 6 As shown, a support base 4 is provided inside the guide groove 12a, and a first elastic reset member 5 (which can be a spring, etc.) is fixedly connected to the bottom of the guide groove 12a. The support base 4 is supported by the first elastic reset member 5 below it, providing an upward lifting force for the mounting shaft 2. A friction seat 6 is also provided inside the guide groove 12a, and a second elastic reset member 7 (which can be a spring, etc.) is fixedly connected to the top of the guide groove 12a. The friction seat 6 is pressed against the mounting shaft 2 by the second elastic reset member 7 above it. The materials of the first elastic reset member 5 and the second elastic reset member 7 are set according to the weight of the fully loaded coil. The first elastic reset member 5 can be made of a material with higher strength.

[0043] The support base 4 can make partial contact with the bottom of the mounting shaft 2, resulting in a smaller contact area and thus less friction. At the same time, the support base 4 can be made of a material with low friction, such as polyoxymethylene (POM), or the surface of the support base 4 can be inlaid with ball bearings 8. The support base 4 made of POM material has a smooth surface to further reduce frictional resistance and ensure that the mounting shaft 2 rotates more smoothly on the support base 4.

[0044] The inner surface of the friction seat 6 that contacts the mounting shaft 2 can be machined into a matching arc surface, thereby significantly increasing the contact area and generating greater friction. At the same time, the friction seat 6 can be made of a material with a high coefficient of friction, such as rubber, polyurethane, or sintered copper-based friction material.

[0045] When the roll is fully loaded, its weight is significant, causing the mounting shaft 2 to compress the first elastic reset member 5 and move downwards. At this time, the pressure between the mounting shaft 2 and the top friction seat 6 is relatively small, resulting in low friction. Similarly, the friction between the mounting shaft 2 and the bottom support seat 4 is also low, allowing the roll to be easily pulled. As the roll is consumed, its weight gradually decreases. Under the rebound force of the first elastic reset member 5, the entire mounting shaft 2, along with the remaining roll, gradually moves upwards, causing a continuous increase in pressure between the mounting shaft 2 and the top friction seat 6. This leads to a significant increase in the sliding friction between them. This gradually increasing friction provides increasing resistance to the roll's rotation, effectively suppressing excessive rotation due to inertia, thus preventing tape loosening and tape scrambling, and ensuring stable and reliable material supply. It should be noted that throughout the process, the bottom support seat 4 primarily serves to support and ensure smooth vertical movement; the small amount of friction it generates does not affect the dominant damping adjustment function.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
