Abstract
Description
Technical Field
[0001] This utility model relates to the field of MLCC capacitor technology, and in particular to a large-width MLCC tape reel taping device. Background Technology
[0002] MLCC (Multi-layer ceramic capacitor) is an abbreviation for multilayer ceramic chip capacitor, a type of capacitor widely used in circuits, also known as a "monolith capacitor". Capacitors are important electronic components, serving as containers for storing electrical charge, and have functions such as DC blocking, AC passing, resonance, filtering, bypassing, and coupling.
[0003] To facilitate high-speed automated placement production in SMT processes and prevent MLCC breakage due to collisions during transportation, MLCC capacitors often need to be taped and reeled in the back-end processes of MLCC production. However, traditional MLCC taping and reeling equipment can only accommodate a small roll width of the cover reel. During production, frequent machine stops are required to replace the cover reel, resulting in significant wear on both the front and back of the cover reel, as well as high labor costs and time.
[0004] It should be noted that the information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model, and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content
[0005] To address the technical problem of frequent downtime for cover tape reel replacement in traditional MLCC taping equipment, resulting in significant wear before and after the cover tape roll, this invention provides a large-width cover tape reel MLCC taping device. This device includes a machine body, an unwinding mechanism, a guiding mechanism, a carrier tape reel, and a hopper. The machine body is equipped with a sealing mechanism. The unwinding mechanism is located on the top of the machine body and has a cover tape reel. The guiding mechanism is located on the machine body and is movably connected to the cover tape on the cover tape reel, guiding the cover tape into the sealing mechanism. The carrier tape reel and the hopper are both located on the machine body.
[0006] Furthermore, the unwinding mechanism includes a fixed frame, a motor, and a cover tape reel bracket. The fixed frame is fixed to the top of the machine body, the motor is disposed inside the fixed frame, and the output end of the motor passes through the fixed frame and is connected to the cover tape reel bracket for transmission.
[0007] Furthermore, the large-width cover reel MLCC taping device also includes a guide shaft, one end of which is fixed to the fixed frame.
[0008] Furthermore, the unwinding mechanism also includes a locking element, which is movably connected to the cover tape tray support.
[0009] Furthermore, the motor is a variable speed motor.
[0010] Furthermore, the guiding mechanism includes a first guide wheel group and a second guide wheel group, which are arranged perpendicularly to each other.
[0011] Furthermore, the first guide wheel assembly includes a first guide wheel and a plurality of second guide wheels spaced apart from each other, with the first guide wheel located below the guide shaft;
[0012] The second guide wheel assembly includes several horizontally spaced third guide wheels.
[0013] Furthermore, the large-width cover reel MLCC taping device also includes an unwinding control mechanism located below the first guide wheel assembly.
[0014] Furthermore, the unwinding control mechanism includes a first sensor, a second sensor, and a swing arm. The first sensor and the second sensor are disposed below the first guide wheel assembly. One end of the swing arm is movably disposed below the second sensor and movably connected to the second sensor. The other end of the swing arm can at least cover the sensing area of the first sensor.

[0024] Detailed Implementation
[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0026] In the description of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Additionally, the term "comprising" and any variations thereof mean "at least comprising."
[0027] like Figure 1As shown, traditional tape feeding equipment typically places both the cover tape reel and the carrier tape reel on the front surface of the equipment, guided by several sets of rollers to guide the cover tape and carrier tape into the sealing mechanism for sealing. However, the position of the cover tape reel is limited by the exit of the sealing mechanism, resulting in a smaller roll width. During production, when a few cover tapes are used up, the machine needs to be stopped to replace the cover tape reel, resulting in a long waste at both the front and rear ends of each cover tape reel. This undoubtedly increases production costs, and frequent downtime also leads to production delays and decreased efficiency.
[0028] Please see Figure 2 , Figure 2 This is a schematic diagram of the structure of a large-width cover tape reel MLCC taping device provided in an embodiment of the present invention.
[0029] To address the technical problem of frequent downtime for replacing the cover reel in traditional MLCC taping equipment, resulting in significant wear before and after the cover reel, or to achieve at least one or more of the aforementioned advantages, this utility model provides a large-width cover reel MLCC taping device. As shown in the figure, this large-width cover reel MLCC taping device includes a machine body 10, an unwinding mechanism 20, a guiding mechanism 30, a carrier reel 40, and a hopper 50.
[0030] The unwinding mechanism 20, guiding mechanism 30, carrier reel 40, and hopper 50 are all mounted on the machine body 10. The unwinding mechanism 20 has a cover reel 60. A cover tape 61 is wound on the cover reel 60. A carrier tape 41 is wound on the carrier reel 40. The hopper 50 contains MLCC capacitors and can arrange them orderly on the carrier tape 41.
[0031] The casing 10 is also equipped with a molding and encapsulation mechanism 11. The guide mechanism 30 can guide the cover tape 61 into the molding and encapsulation mechanism 11 to cooperate with the carrier tape 41 to complete the molding and encapsulation of the MLCC capacitor. Of course, the casing 10 can also have conventional control panel, operation buttons and other components required for operating the equipment (not shown in the figure), and there are no restrictions on this.
[0032] The unwinding mechanism 20 is located at the top of the machine body 10. In specific implementation, as follows: Figure 3 As shown, the unwinding mechanism 20 includes a fixed frame 21, a motor 22, and a cover tape reel bracket 23. The fixed frame 21 is fixedly installed on the top of the machine body 10, which allows for the selection and installation of a large-width cover tape reel 60 according to actual production needs, reducing the frequency of downtime for replacement and reducing the wear of the cover tape 61 caused by replacing the cover tape reel 60.
[0033] The motor 22 is housed within the fixed frame 21, and its output end passes through the fixed frame 21 and is connected to the cover tape reel bracket 23 for transmission. The cover tape reel bracket 23 is used to mount the cover tape reel 60. When the motor 22 rotates, it drives the cover tape reel bracket 23 and the cover tape reel 60 to rotate simultaneously, releasing the cover tape 61 for sealing. Preferably, the motor 22 is a variable speed motor, which can adjust the speed of the motor 22 according to the production progress to maintain the tension of the cover tape 61 and prevent it from falling off.
[0034] Furthermore, the unwinding mechanism 20 also includes a locking element 24. The locking element 24 is movably connected to the cover reel bracket 23. The locking element 24 and the cover reel bracket 23 are detachably connected. The locking element 24 secures the cover reel 60 and prevents the cover reel 60 from falling off during production.
[0035] Based on the above, the large-width cover tape reel MLCC taping device also includes a guide shaft 70. One end of the guide shaft 70 is fixed to the fixed frame 21. The guide shaft 70 can provide initial guidance and guide the cover tape 61 into the guide mechanism 30, avoiding friction between the cover tape 61 and the machine body 10.
[0036] The guiding mechanism 30 includes a first guide wheel group 31 and a second guide wheel group 32. The first guide wheel group 31 and the second guide wheel group 32 are arranged perpendicular to each other, and the guiding direction of the second guide wheel group 32 is opposite to the setting direction of the sealing mechanism 11.
[0037] In specific implementation, such as Figure 4 , Figure 5 As shown, the first guide wheel assembly 31 includes a first guide wheel 311 and a plurality of second guide wheels 312 arranged at intervals between each other. The first guide wheel 311 is located below the guide shaft 70. The plurality of second guide wheels 312 are arranged sequentially at intervals on the side of the first guide wheel 311 near the second guide wheel assembly 32. When the cover strap 61 is led out via the guide shaft 70, it is first changed direction and guided by the first guide wheel 311, and then guided onto the plurality of second guide wheels 312.
[0038] The second guide roller group 32 includes several horizontally spaced third guide rollers 321. When the cover tape 61 is guided to the third guide rollers 321 after passing through several second guide rollers 312, the cover tape 61 changes direction again and is guided into the encapsulation mechanism 11 through several third guide rollers 321, and cooperates with the carrier tape 41 to encapsulate the MLCC capacitor.
[0039] Furthermore, to improve the control precision of the motor 22 and prevent the cover tape 61 from falling off, the large-width cover tape reel MLCC taping device also includes an unwinding control mechanism 80. The unwinding control mechanism 80 is located below the first guide wheel group 31.
[0040] In a specific implementation, the unwinding control mechanism 80 includes a first sensor 81, a second sensor 82, and a swing arm 83. The first sensor 81 and the second sensor 82 are disposed below the first guide wheel assembly 31. One end of the swing arm 83 is movably disposed below and movably connected to the second sensor 82. The other end of the swing arm 83 can at least cover the sensing area of the first sensor 81.
[0041] Specifically, there are at least three second guide wheels 312. One end of the swing arm 83 is rotatably disposed below the second sensor 82. The other end of the swing arm 83 is provided with a fourth guide wheel 831. After the cover tape 61 is guided by the first guide wheel 311, it is guided to the first second guide wheel 312 near the first guide wheel 311, then it is guided downwards around the fourth guide wheel 831 and upwards to the second second guide wheel 312 near the first guide wheel 311. Finally, it is guided to the sealing mechanism 11 by the cooperation of the third second guide wheel 312 and the third guide wheel 321.
[0042] If the cover strap 61 shortens due to forward conveying, it will cause the swing arm 83 to swing upward. When the swing arm 83 covers the sensing area of the first sensor 81, the motor 22 will rotate to continue releasing the cover strap 61. When the swing arm 83 leaves the sensing area of the first sensor 81, the motor 22 will stop rotating, thus achieving precise control of the cover strap 61, maintaining its tautness, and preventing it from falling off.
[0043] If the cover tape 61 on the cover tape reel 60 is used up, and the cover tape 61 cannot exert an upward force on the swing arm 83, the swing arm 83 will swing downward, causing the end of the swing arm 83 close to the second sensor 82 to contact the second sensor, triggering the alarm device to stop and reminding the staff to replace the cover tape reel 60.
[0044] It is understandable that the first sensor 81 and the second sensor 82 can be conventional infrared sensors, pressure sensors, or other devices, and this case does not impose any restrictions on this.
[0045] In some preferred embodiments, the large-width cover reel MLCC taping device also includes an indicator light 90. The indicator light 90 is located on the machine body 10 and is used to confirm whether the equipment is in normal working condition or abnormal shutdown condition.
[0046] In summary, the large-width cover tape reel MLCC taping device provided by this utility model, compared with the prior art, adjusts the installation position of the cover tape reel to a position at the top of the equipment where space is not restricted. It can install large-width cover tape reels according to actual needs, and guide the cover tape into the sealing mechanism in conjunction with the guiding mechanism, reducing the frequency of downtime to replace the cover tape reel, thereby reducing the loss before and after the cover tape roll, reducing production costs and improving production efficiency.

These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
[0048] Furthermore, those skilled in the art should understand that although many problems exist in the prior art, each embodiment or technical solution of this utility model can be improved in only one or a few aspects, without necessarily solving all the technical problems listed in the prior art or background art simultaneously.
