Description

Technical Field

[0001] This application relates to the field of machining, and in particular to an automatic folding device for a capacitor tape and reel machine. Background Technology

[0002] In the electronics manufacturing industry, capacitor taping machines are crucial equipment for packaging capacitors, playing a key role in improving production efficiency and packaging quality. With the continuous development of the electronics industry, the requirements for the automation level and production precision of capacitor taping machines are also increasing. The efficient and stable operation of capacitor taping machines provides strong support for the large-scale production of electronic devices, driving the rapid development of the entire electronics industry.

[0003] In capacitor tape and reel machine technology, the folding operation of capacitor tape and reel has traditionally been done manually. Workers need to manually bend and fold the capacitor tape and reel, which is not only inefficient but also prone to inconsistent folding precision. In addition, there are some methods that use simple mechanical devices to assist in folding, such as using fixed molds to compress the capacitor tape and reel, but this method lacks flexibility and is difficult to adapt to different specifications of capacitor tape and reel. There are also methods that use ordinary rollers to guide and initially bend the capacitor tape and reel, but these still have shortcomings in terms of folding effect and quality.

[0004] Existing technologies have significant drawbacks in capacitor tape folding. Manual folding is inefficient and cannot meet the needs of large-scale production. Moreover, manual operation is easily affected by human factors, resulting in unstable folding accuracy. Simple mechanical devices and ordinary rollers lack flexibility and cannot well adapt to the folding requirements of different capacitor tape specifications, making it difficult to guarantee the quality and consistency of folding. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this application provides an automatic folding device for a capacitor tape machine, which can realize automatic folding of capacitor tape, improve folding efficiency and quality, and reduce the possibility of capacitors or capacitor tape being damaged during the folding process.

[0006] This application is achieved through the following technical solution: An automatic folding device for a capacitor tape and reel machine includes: The worktable has limit plates on both sides. The end of the limit plate away from the capacitor tape machine has several insertion holes, and a limit rod is provided in the insertion holes. A buffer layer is provided on the limit rod. The limit plate or limit rod can apply a reaction force to the capacitor tape during feeding, so as to drive the capacitor tape to form a bending part when it comes into contact with the limit plate. The guide wheel is located at the end of the worktable near the capacitor tape machine. It is used to keep the capacitors on the capacitor tape in a vertical position and guide the capacitor tape into the placement space formed by the limiting plate and the limiting rod. The clamping mechanism includes a clamping plate and a telescopic mechanism; the clamping plate is symmetrically arranged on both sides of the placement space; the telescopic mechanism is used to provide power to the clamping plate to drive the clamping plate to move intermittently in a straight line along the capacitor tape feeding direction, thereby squeezing and folding the bent parts of the capacitor tape near the limit plates on both sides of the worktable.

[0007] By adopting the above technical solution, the limiting plates on both sides of the worktable and the limiting rods away from the end of the capacitor tape machine can apply a reaction force to the capacitor tape during feeding. When the capacitor tape is fed to abut against the limiting rods, it encounters resistance in the feeding direction, causing it to bend and deform, and then turn towards the limiting plate. When the capacitor tape abuts against the limiting plate, due to the interaction of forces, it will bend and deform again at the point of contact with the limiting plate, forming a bend, which creates conditions for subsequent folding operations. The guide wheels are located at the end of the worktable near the capacitor tape machine. Utilizing their circumferential rotation characteristics, they can keep the long side of the capacitor tape vertical, allowing the capacitor tape to accurately enter the limiting plate and the limiting rods. Within the space enclosed by the positioning rods, the stability and accuracy of the tape feeding are ensured. The telescopic mechanism in the clamping mechanism provides power to the clamping plate, enabling it to intermittently move linearly along the capacitor tape feeding direction. When the clamping plate moves to the bent part of the limit plates on both sides of the worktable on the capacitor tape, it is squeezed and folded, realizing the automatic folding function of the capacitor tape, improving production efficiency, reducing labor costs, and ensuring the consistency of folding quality. In addition, the limit rods are equipped with a buffer layer to provide buffer space for the capacitor tape, reducing damage to the capacitor or capacitor tape when the clamping plate squeezes the capacitor tape. At the same time, the insertion holes of the limit plates allow for easy adjustment of the position of the limit rods to meet different production needs.

[0008] Optionally, the worktable is provided with two pairs of vertically arranged fixed shafts in the middle, and the guide wheel is rotatably connected to the fixed shafts.

[0009] By adopting the above technical solution, two pairs of vertically arranged fixed shafts are set in the middle of the workbench and the guide wheels are rotatably connected to the fixed shafts. This allows the guide wheels to be installed stably, enabling them to better keep the long side of the capacitor tape vertical and guide the capacitor tape into the placement space.

[0010] Optionally, the buffer layer is an airbag or flexible rubber covering the limiting rod.

[0011] By adopting the above technical solutions, the airbag or flexible rubber can provide support while having a certain deformation capacity, avoiding the hard compression of the capacitor tape by the pressure plate and reducing the possibility of the capacitor and capacitor tape being crushed and damaged.

[0012] Optionally, the telescopic mechanism is arranged below the worktable; the worktable is provided with clearance grooves on both sides to accommodate the clamping plate.

[0013] By adopting the above technical solution, the telescopic mechanism is arranged under the worktable to avoid interference with the feeding of the capacitor tape and ensure the smooth folding process of the capacitor tape. The worktable is provided with clearance grooves for the pressure plate to provide space for the movement of the pressure plate, so that the pressure plate can move smoothly in a straight line along the feeding direction of the capacitor tape and squeeze and fold the bent part on the capacitor tape.

[0014] Optionally, the telescopic mechanism is a pneumatic telescopic rod, and the clamping plate is detachably connected to the movable end of the telescopic mechanism.

[0015] By adopting the above technical solution, the pneumatic telescopic rod, as the telescopic mechanism, provides power to the pressure plate, enabling stable and efficient linear motion. Compared with the telescopic mechanism of screw rotation, it responds quickly and facilitates driving the pressure plate to move intermittently along the capacitor tape feeding direction. Of course, if cost is not a consideration, the telescopic mechanism can also be in the form of a linear motor. The pressure plate is detachably connected to the movable end of the telescopic mechanism, making it convenient to replace, repair, and maintain the pressure plate.

[0016] Optionally, the clamping plate has an L-shaped structure, including a horizontal part and a vertical part. The vertical part is detachably connected to the movable end of the telescopic mechanism, and the horizontal part is located above the worktable to apply extrusion force to the bent part of the capacitor tape.

[0017] By adopting the above technical solution, the horizontal part of the L-shaped clamping plate is set above the worktable, which can more accurately apply pressure to the bent part of the capacitor tape. At the same time, the detachable connection facilitates the replacement and maintenance of the clamping plate.

[0018] Optionally, the movable end of the telescopic mechanism is provided with a fixed seat, the fixed seat is provided with a guide rod, the pressing plate is slidably connected to the guide rod, and an elastic reset member is provided between the fixed seat and the pressing plate; the elastic reset member is used to provide pre-tightening force when the pressing plate squeezes the bent part.

[0019] By adopting the above technical solution, the elastic reset component provides pre-tension force when the clamping plate squeezes the bent part of the capacitor tape, achieving flexible squeezing of the capacitor tape. This flexible squeezing method avoids hard squeezing of the capacitor tape, thus effectively preventing damage caused by hard squeezing and ensuring the integrity and quality of the capacitor tape. At the same time, the elastic reset component gives the clamping plate a certain buffering capacity during the squeezing process, which can better adapt to changes in the shape and size of the capacitor tape, improving the stability and reliability of the folding operation; moreover, flexible squeezing can also reduce the impact on the internal capacitor elements of the capacitor tape during the squeezing process, reducing the risk of capacitor damage and extending the service life of the capacitor tape.

[0020] Alternatively, the elastic reset element may be a reset spring sleeved on the guide rod.

[0021] By adopting the above technical solution, the reset spring is sleeved on the guide rod, which can stably provide pre-tightening force when the pressure plate squeezes the bent part, ensuring the squeezing effect of the pressure plate on the bent part of the capacitor tape. Its structure is simple and the manufacturing cost is low.

[0022] Optionally, the fixed base is provided with a displacement sensor for sensing the distance between the pressing plate and the fixed base, and the displacement sensor and the telescopic mechanism are electrically connected to the control unit of the device.

[0023] By adopting the above technical solution, the displacement sensor can sense the distance between the pressure plate and the fixed seat in real time, and the control unit can accurately control the telescopic mechanism based on the sensing data to ensure that the pressure plate's squeezing and folding operation on the capacitor tape bending part is more precise and stable.

[0024] Optionally, the end of the clamping plate is provided with an arc-shaped section.

[0025] By adopting the above technical solution, the pressing plate can more smoothly compress the bent part of the capacitor tape, reducing damage to the capacitor tape, lowering the risk of tape damage, and ensuring the smoothness of the capacitor tape folding process.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The limiting plate or limiting rod of this application applies a reaction force to the capacitor tape during feeding to form a bent part, and the pressing mechanism squeezes and folds the bent part to realize automatic folding of the capacitor tape, improve folding efficiency, and meet the needs of large-scale production; 2. The guide wheel in this application keeps the long side of the capacitor tape vertical and guides it into the placement space, which helps to improve folding accuracy and ensure folding quality and consistency; 3. The entire device of this application can be adapted to the folding requirements of different specifications of capacitor tape by adjusting the limiting plate and the clamping mechanism, thereby improving the flexibility of the device.

[0029] The technical solutions of various embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Example 1 Reference Figures 1 to 3 This application discloses an automatic folding device for a capacitor tape and reel machine, comprising: The workbench 1 has limit plates 11 on both sides. The end of the limit plate 11 away from the capacitor tape 4 machine is provided with several insertion holes 111. Limiting rods 12 are provided in the insertion holes 111. A buffer layer is provided on the limiting rods 12. The limit plate 11 or the limiting rods 12 can apply a reaction force to the capacitor tape 4 in the feed, so as to drive the capacitor tape 4 to form a bending part when it comes into contact with the limit plate 11. The guide wheel 2 is set at the end of the worktable 1 near the capacitor tape 4 machine to keep the long side of the capacitor tape 4 vertical and guide the capacitor tape 4 into the placement space formed by the limiting plate 11 and the limiting rod 12. The clamping mechanism 3 includes a clamping plate 31 and a telescopic mechanism 32. The clamping plate 31 is symmetrically arranged on both sides of the placement space. The telescopic mechanism 32 is used to provide power to the clamping plate 31 so as to drive the clamping plate 31 to move intermittently in a straight line along the feeding direction of the capacitor tape 4, thereby squeezing and folding the bent parts of the capacitor tape 4 near the limiting plates 11 on both sides of the worktable 1.

[0031] Specifically, refer to Figures 1 to 3 Limiting plates 11 are formed on both sides of the workbench 1. Several insertion holes 111 are provided at the end of the limiting plate 11 away from the capacitor tape and reel machine 4, into which limiting rods 12 are inserted. The limiting plates 11 and limiting rods 12 can be made of metal, such as stainless steel, which has high strength and wear resistance, allowing for long-term use without damage. Alternatively, high-strength plastic can be used, which is lightweight and low-cost. The limiting rods 12 and the limiting plates 11 can be connected by bolts to enhance their connection. The connection is reliable and easy to disassemble and replace. The limiting plate 11 or the limiting rod 12 can apply a reaction force to the capacitor tape 4 during feeding. When the capacitor tape 4 is fed to abut against the limiting rod 12, the capacitor tape 4 will be resisted in the feeding direction and will bend and deform, and then turn to move towards the limiting plate 11. When the capacitor tape 4 abuts against the limiting plate 11, due to the interaction of forces, the capacitor tape 4 will bend and deform again at the part that abuts against the limiting plate 11, forming a bent part, which creates conditions for subsequent folding operations.

[0032] Reference Figures 1 to 3 The buffer layer is an airbag 121 covering the limiting rod 12. The airbag 121 can provide support while having good deformation ability, avoiding the hard compression of the capacitor tape 4 by the clamping plate 31, and reducing the possibility of the capacitor and capacitor tape 4 being crushed and damaged.

[0033] The worktable 1 has two pairs of vertically arranged fixed shafts 13 in the middle. The fixed shafts 13 can be cylindrical and made of carbon steel, which has a certain strength. The fixed shafts 13 and the worktable 1 can be connected by interference fit to ensure the stability of the connection.

[0034] Reference Figures 1 to 3The guide wheel 2 is located at the end of the worktable 1 near the capacitor tape 4 machine. The guide wheel 2 is rotatably connected to the fixed shaft 13. The guide wheel 2 can be made of aluminum alloy, which is lightweight and rotates flexibly. The outer wall of the guide wheel 2 is provided with a rubber layer, which can increase the friction with the capacitor tape 4 and better guide the capacitor tape 4. The rubber layer can also be made of silicone, which has good flexibility and wear resistance. The function of the guide wheel 2 is to keep the long side of the capacitor tape 4 in a vertical state and guide the capacitor tape 4 into the placement space formed by the limiting plate 11 and the limiting rod 12. The guide wheel 2 and the fixed shaft 13 can be connected by a bearing to reduce the friction during rotation and make the guide wheel 2 rotate more smoothly.

[0035] Reference Figures 1 to 3 The clamping mechanism 3 includes a clamping plate 31 and a telescopic mechanism 32. The clamping plate 31 is symmetrically arranged on both sides of the placement space. The clamping plate 31 has an L-shaped structure. This structure can better squeeze and fold the bent parts of the capacitor tape 4 near the limit plates 11 on both sides of the worktable 1.

[0036] Reference Figures 1 to 3 The clamping plate 31 can be made of mold steel, which has high hardness and wear resistance. The end of the clamping plate 31 is provided with an arc section 313, which can avoid damage to the capacitor tape 4 during the compression and folding process. The telescopic mechanism 32 is used to provide power to the clamping plate 31 to drive the clamping plate 31 to move intermittently in a straight line along the feeding direction of the capacitor tape 4.

[0037] Reference Figures 1 to 3 The telescopic mechanism 32 is arranged below the worktable 1. The worktable 1 has clearance grooves 14 on both sides to accommodate the clamping plate 31, so that the clamping plate 31 is not obstructed by the worktable 1 during movement. The telescopic mechanism 32 is a pneumatic telescopic rod, which has the advantages of fast response and large thrust. As a prior art, the pneumatic telescopic rod is electrically connected to the control unit of the device. The control unit can set the movement cycle of the clamping plate 31 according to the feeding rhythm of the capacitor tape 4 to achieve intermittent reciprocating motion of "forward-stop-backward". Of course, the telescopic mechanism 32 can also be an electric push rod, which has higher control precision. The clamping plate 31 is detachably connected to the movable end of the telescopic mechanism 32. The detachable connection method can be bolt connection, which makes it convenient to replace clamping plates 31 of different specifications to adapt to different capacitor tapes 4.

[0038] The implementation principle of this embodiment is as follows: the capacitor tape 4 enters the placement space of the worktable 1 under the guidance of the guide wheel 2. The limiting plate 11 and the limiting rod 12 apply a reaction force to the capacitor tape 4 to form a bent part. The telescopic mechanism 32 drives the pressing plate 31 to move linearly along the feeding direction of the capacitor tape 4 to squeeze and fold the bent part. The displacement sensor 324 monitors the position of the pressing plate 31 in real time and accurately controls the action of the telescopic mechanism 32. This automatic folding device improves the folding efficiency and accuracy of the capacitor tape 4, can adapt to capacitor tape 4 of different specifications, solves the problems existing in the prior art, and has good practicality and promotion value.

[0039] Example 2 Reference Figures 4 to 5 The difference between this embodiment and the first embodiment is that the buffer layer is a flexible rubber 122 covering the limiting rod 12. The flexible rubber 122 can provide support while having a certain deformation capability, avoiding the hard compression of the capacitor tape 4 by the clamping plate 31, and reducing the possibility of the capacitor and capacitor tape 4 being crushed and damaged.

[0040] Reference Figures 4 to 5 The movable end of the telescopic mechanism 32 is provided with a fixed seat 321. The fixed seat 321 has an L-shaped structure and can be made of cast iron, which has good stability. The fixed seat 321 is provided with a guide rod 322. The guide rod 322 can be circular and made of stainless steel. The clamping plate 31 is slidably connected to the guide rod 322.

[0041] Reference Figures 4 to 5 An elastic reset element 323 is provided between the fixed base 321 and the pressure plate 31. The elastic reset element 323 is a reset spring sleeved on the guide rod 322. The reset spring can provide pre-tightening force when the pressure plate 31 squeezes the bent part to ensure the squeezing effect.

[0042] Reference Figures 4 to 5 The fixed base 321 is equipped with a displacement sensor 324 for sensing the distance between the pressure plate 31 and the fixed base 321. The displacement sensor 324 can monitor the position of the pressure plate 31 in real time, and then determine the value of the preload of the return spring so as to accurately control the action of the telescopic mechanism 32. When the value sensed by the displacement sensor 324 reaches the preset value, the telescopic mechanism 32 can stop squeezing the braided belt and drive the pressure plate 31 to move away from the braided belt, disengage from the braided belt, and prepare for the next squeezing.

[0043] The implementation principle of this embodiment is as follows: the capacitor tape 4 enters the placement space of the worktable 1 under the guidance of the guide wheel 2. The limiting plate 11 and the limiting rod 12 apply a reaction force to the capacitor tape 4 to form a bent part. The telescopic mechanism 32 drives the pressing plate 31 to move linearly along the feeding direction of the capacitor tape 4 to squeeze and fold the bent part. At this time, the return spring provides pre-tension force to ensure the squeezing effect. The displacement sensor 324 monitors the position of the pressing plate 31 in real time and accurately controls the action of the telescopic mechanism 32. This automatic folding device, while ensuring the improvement of the folding efficiency and accuracy of the capacitor tape 4 and adapting to different specifications of capacitor tape 4, further improves the squeezing and folding effect through the pre-tension force of the return spring, solves the problems existing in the prior art, and has good practicality and promotion value.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
