Description

Technical Field

[0001] This invention relates to the field of capacitor manufacturing technology, and in particular discloses an intelligent production equipment for capacitors. Background Technology

[0002] Capacitors are indispensable components in electronic products, widely used in consumer electronics, communication equipment, power systems, and new energy fields. To meet market demand for high-performance, miniaturized, and long-life capacitors, capacitor production equipment and manufacturing processes are gradually developing towards higher precision, higher efficiency, and greater intelligence. However, existing capacitor production equipment still has some technical problems that limit further improvements in product quality and production efficiency.

[0003] In the material processing, the thickness uniformity and surface smoothness of the thin film material are crucial. Traditional lamination equipment suffers from uneven pressure distribution, which can easily lead to inconsistent film thickness or surface defects, thus affecting the dielectric performance and reliability of the capacitor. Furthermore, in the production of multilayer capacitors, the high alignment accuracy required in the winding process means that existing equipment's alignment and positioning mechanisms are insufficient, easily causing interlayer misalignment and reducing yield.

[0004] Therefore, in response to the above problems, developing a new type of capacitor production equipment that can improve processing accuracy, automation level and energy efficiency has become a key direction for the industry's development. Summary of the Invention

[0005] In order to overcome the above-mentioned shortcomings and deficiencies in the prior art, the purpose of this invention is to provide an intelligent production device for capacitors.

[0006] To achieve the above objectives, the present invention provides an intelligent production equipment for capacitors, comprising a film pressing device, a capacitor winding device, and a lead soldering device.

[0009] Furthermore, the film pressing device includes a base, a support platform mounted on the base for carrying external film rolls, a pressure plate reciprocatingly mounted on the base, and a first driving member connected to the pressure plate, the first driving member being used to drive the pressure plate to press and flatten the film roll located on the base.

[0010] Furthermore, the unwinding mechanism includes an unwinding roller rotatably mounted on the winding table and a second driving member connected to the unwinding roller. The film roll is used to be sleeved on the unwinding roller, and the second driving member is used to drive the unwinding roller to rotate and unwind the film roll to the winding needle. The film roll includes an insulating film roll and a metal film roll. The unwinding mechanism is provided in three sets. One set of unwinding mechanisms is used to unwind the insulating film roll to the winding needle, and the other two sets of unwinding mechanisms are used to unwind the metal film roll to the winding needle.

The film guiding mechanism includes an inclined seat slidably disposed on the winding table and a first linear module connected to the inclined seat. The inclined seat is provided with a fixed plate and a movable plate that reciprocates relative to the fixed plate. One end of the movable plate is connected to a first cylinder.

The output end of the rotating assembly is provided with a clutch. One end of the winding needle is connected to the rotating structure via the clutch, and the other end of the winding needle is provided with a winding needle support. The second linear module is used to drive the release handle to work in conjunction with the winding needle support to pull the winding needle away from the capacitor element.

[0016] Furthermore, the capacitor winding device also includes a first picking robot that is reciprocatingly mounted on the winding table and a first unloading conveyor belt located below the first picking robot. The capacitor elements processed by the winding mechanism are picked up by the first picking robot and fed to the first unloading conveyor belt. The first unloading conveyor belt is used to transport the capacitor elements picked up by the first picking robot to the loading conveyor belt of the lead soldering device.

[0017] Furthermore, the lead soldering device includes a soldering table, a flipping feeding mechanism, a lead feeding mechanism, and a soldering mechanism, all mounted on the soldering table. The flipping feeding mechanism includes a feeding conveyor belt for conveying capacitor elements and a flipping feeding robot at the end of the feeding conveyor belt. The soldering mechanism includes a turntable rotatably mounted on the soldering table and a fourth drive unit connected to the turntable. The turntable is equipped with a second picking robot that works in conjunction with the flipping feeding robot. The soldering mechanism also includes a fixed plate mounted on the soldering table and located above the turntable. The fixed plate is equipped with a soldering gun and a solder wire feeding assembly. The lead feeding mechanism is used to convey external conductive leads to the metal film of the capacitor elements picked up by the second picking robot.

A spot welder is also provided on the fixed plate. The pin transfer robot is used to transfer the conductive pins bent and cut by the pin bending head to the capacitor element held by the second picking robot. Then, the spot welder spot welds the conductive pins to the capacitor element for subsequent soldering processing by the soldering mechanism.

[0019] Furthermore, the second picking robot is provided in multiple sets, which are arranged around the central axis of the turntable. The welding table is also provided with an adjustment mechanism, which includes a top material column that is reciprocally moved on the welding table and a fifth driving component connected to the top material column. The fifth driving component is used to drive the top material column to abut against the capacitor element picked up by the second picking robot to cooperate with the welding action of the welding mechanism.

[0020] Furthermore, the production equipment also includes an automated control system specifically designed to monitor and coordinate the operation of the film pressing device, capacitor winding device, and lead bonding device. The control system includes a central processing unit, interface modules (including communication interfaces for connecting to external networks and bus interfaces for connecting to internal devices), sensor arrays (distributed across key components, such as tension sensors for the unwinding mechanism, speed and position sensors for the winding mechanism, and temperature and pressure sensors for the bonding device), and actuator control modules (directly controlling the actuators of each mechanical component, such as the aforementioned drive units).

[0021] The seamless integration between systems is ensured through both software and hardware layers. On the software layer, an integrated software platform allows for the programming and monitoring of all equipment operations, enabling flexible adjustment of the operating parameters and sequence of each device according to production needs. On the hardware layer, a bus system connects the control modules of each device to the central processing unit, ensuring rapid and accurate command transmission. Simultaneously, the overall system design allows for real-time monitoring of the operating status of each component, enabling timely responses to changes in various production conditions.

[0022] The technical principle of this invention: This invention provides an intelligent production equipment for capacitors, mainly including a film pressing device, a capacitor winding device, and a lead bonding device. The film pressing device is used to flatten the surface of the film roll to ensure the uniformity of the film. The capacitor winding device conveys the film roll to the winding needle through an unwinding mechanism, and uses a rotating component to drive the winding needle to rotate and wind the film roll into a capacitor element. The device also includes an adhesive applicator for fixing the first end of the film roll and sealing the edges, and a cutting mechanism for cutting the film roll after the capacitor element is formed. The lead bonding device is responsible for bonding the external conductive leads to the capacitor element, completing the entire production process.

[0023] The beneficial effects of this invention are as follows: This intelligent production equipment achieves high efficiency, precision, and continuity in capacitor production through automated control of each stage. The film pressing device effectively ensures film quality and thickness uniformity, while the winding device ensures consistent capacitor element morphology by precisely controlling film tension and position. The coordination of multiple unwinding and tensioning mechanisms improves film stability, and the adhesive application and cutting mechanisms precisely control edge sealing and cutting effects. Furthermore, the lead soldering device employs advanced soldering technology, improving soldering quality and efficiency.

[0037] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0038] Please see Figures 1 to 11 As shown, the intelligent production equipment for capacitor production according to the present invention mainly includes a film pressing device 1, a capacitor winding device 2, and a lead bonding device 3. The entire production process begins with the film pressing device 1 flattening the film roll, and then the processed film is fed into the winding mechanism 22 through the unwinding mechanism 21. In the winding mechanism 22, the film roll is wound into a capacitor element, and the edges are sealed and cut by the adhesive applicator 23 and the cutting mechanism 24. Finally, the lead bonding device 3 bonds the conductive leads to the capacitor element, completing the production of the entire capacitor.

[0039] In this embodiment, the film pressing device 1 consists of a base 11, a support platform 12, a pressure plate 13, and a first driving component 14. The first driving component 14 is a hydraulic system. The support platform 12 is provided with a material tray with an adjustable diameter for limiting the film roll. The pressure plate 13 presses the insulating film roll or metal film roll in the material tray through reciprocating motion to flatten the externally supplied film roll. The flattened film roll (one set of insulating film roll and two sets of metal film roll) is taken over by the unwinding mechanism 21. The unwinding mechanism 21 includes three sets of unwinding rollers 210 and a second driving component 211. One set is used to unwind the insulating film, and the other two sets are used to unwind the metal film simultaneously, thereby ensuring that the two metal films can effectively clamp the insulating film in the middle.

[0040] After unwinding, the film roll enters the winding mechanism 22, which includes three sets of winding needles 221, three rotating components 222, and a linkage disk 223 for coordinating the rotation of the three sets of winding needles 221. One rotating component 222 drives one set of winding needles 221 to wind the film roll unwound by the unwinding mechanism 21. The linkage disk 223 is precisely rotated by a third drive component 224, enabling the switching of the three winding needle positions. To ensure precise control of film tension and position during winding, a tensioning mechanism 25 and a film guiding mechanism 26 are installed. The tensioning mechanism 25 achieves uniform tension control of the film through a swing rod and a first tensioning roller 251 in conjunction with a second tensioning roller. The film guiding mechanism 26 uses a movable plate 264 on an inclined seat 261 and a first cylinder 265 to fix the film.

[0041] In use, the first linear module 262 drives the tilting seat 261 to reciprocate (the first cylinder 265 drives the movable plate 264 to approach the fixed plate 263 to clamp the film roll), and moves the film roll clamped by the fixed plate 263 and the movable plate 264 to the space between the winding needle 221 and the adhesive applicator 23. At the same time, the tape reel 231, under the action of the tape gripper 233 and the tape tension roller 2311 (with multiple strip-shaped protrusions on the surface to facilitate the picking action of the intermediate adhesive applicator roller 235), unwinds the double-sided tape onto the intermediate adhesive applicator roller 235. Then, the first cutter 232 cuts the double-sided tape. After being picked up by the intermediate adhesive applicator roller 235 driven by the linkage drive assembly 234, the double-sided tape is then applied between the metal film and the insulating film, and between the metal film and the winding needle 221, to fix the three layers of film to the winding needle 221 for easy winding operation.

[0042] After the capacitor element is formed, the adhesive applicator 23 and the linkage disk 223 work together to seal and fix the wound capacitor element. Then, the cutting mechanism 24 uses the second cutter 242 to precisely cut the three-layer film. This process is repeated to complete the forming of three sets of capacitor elements. The winding mechanism 22 also includes a release assembly, which separates the winding needle 221 from the capacitor element through the second linear module 271 and the release handle 272. In use, the second linear module 271 drives the winding needle 221 forward through the release handle 272. At this time, the winding needle 221 is connected to the output end of the rotating component 222 via the clutch 2221 for subsequent winding. During separation, the second linear module 271 drives the winding needle 221 backward through the release handle 272. At this time, the winding needle 221 is separated from the rotating component 222 via the clutch 2221. Then, the first picking robot 28 clamps the capacitor element that has separated from the winding needle 221 and transfers it to the first unloading conveyor belt 29. The first unloading conveyor belt 29 is connected to the loading conveyor belt 311 of the lead welding device 3 to cooperate with the flipping loading robot 312.

[0043] Finally, the lead welding device 3, through the coordinated operation of the flipping feeding mechanism 31, the lead feeding mechanism 32, and the welding mechanism 33, precisely welds the external conductive leads to the metal film of the capacitor elements. The operations involved in this part include the conveying of the feeding conveyor belt 311, the rotational delivery of the flipping feeding robot 312 (the capacitor elements on the feeding conveyor belt 311 are arranged radially), and the precise welding operation in coordination with the second picking robot 333 on the turntable 331 and the welding gun 335 on the fixed plate 334.

[0044] Specifically, the flipping loading robot 312 includes a flipping base 312111, which is telescopically mounted on the welding table 30 via a fifth cylinder 3125. A flipping mechanical gripper 3122 is rotatably mounted on the flipping base 312111, which is driven to rotate by a first servo motor 3123 and a gear module. The flipping mechanical gripper 3122 is driven by a fourth cylinder 3124 to generate a gripping action. When stationary, the flipping mechanical gripper 3122 extends into the loading conveyor belt 311. During operation, the two cylinder systems and the servo motor system jointly control the flipping loading robot 312 to flip the capacitor elements in the loading conveyor belt 311 to a vertical state and transfer them to the second picking robot 333. The second picking robot 333 clamps the vertically positioned capacitor elements to facilitate the pin welding operation.

[0045] Specifically, the pin feeding mechanism 32 includes a pin support frame 321 mounted on the welding table 30, a straightening wheel assembly 322 rotatably mounted on the pin support frame 321, a pin gripper 323 (driven by a sixth cylinder 3231) reciprocatingly mounted at the end of the straightening wheel assembly 322, and a pin bending head 324 (driven by a seventh cylinder 3241) reciprocatingly mounted relative to the pin gripper 323. The pin bending head 324 is used to bend and cut the conductive pins transferred by the pin gripper 323. A pin transfer robot 325 is rotatably mounted on the pin support frame 321 above the pin gripper 323. A movable spot welder 3341 is also provided on the fixed plate 334. The pin transfer robot 325 is used to transfer the conductive pins bent and cut by the pin bending head 324 to the capacitor element held by the second picking robot 333. Then, the spot welder 3341 spot welds the conductive pins to the capacitor element for subsequent soldering processing by the welding mechanism 33.

[0046] In the workflow of this equipment, the film roll is first pre-treated by the film pressing device 1 to ensure that the film is flat and wrinkle-free. The treated film is then precisely fed into the winding mechanism 22 by the unwinding mechanism 21. The rotating component 222 operates the winding needle 221 according to the set speed and rotation angle as scheduled by the control system, ensuring that the film is wound into shape in the correct manner. The tensioning and clamping mechanism during the winding process ensures the tension and positional accuracy of the film during winding, avoiding deviations. After the capacitor element is formed, the edge sealing and cutting are completed by the adhesive application and cutting mechanism 24 to ensure the structural integrity and dimensional specifications of the capacitor element. Finally, the lead welding device 3 completes the production of the capacitor element, fixing the conductive leads to the capacitor element through a precise welding process to ensure the electrical performance of the capacitor.

[0047] Through coordinated control of the entire production equipment, each step can be completed automatically without human intervention, greatly improving production efficiency and product quality, and realizing highly automated capacitor production.

[0048] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
