[0024] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0025] See also Figures 1 to 11 As shown, an intelligent production equipment for capacitor production of the present invention mainly includes a film pressing device 1, a capacitor winding device 2 and a pin welding device 3. The entire production process begins with the film pressing device 1 flattening the film coil, and then the processed film is sent to the winding mechanism 22 through the unwinding mechanism 21. In the winding mechanism 22, the film coil is wound into a capacitor element, and the edge is sealed and cut by the gluing mechanism 23 and the cutting mechanism 24. Finally, the pin welding device 3 welds the conductive pins to the capacitor element to complete the production of the entire capacitor.

[0026] In this embodiment, the film pressing device 1 is composed of a base 11, a support platform 12, a pressure plate 13 and a first driving member 14. The first driving member 14 is a hydraulic system. A material plate with an adjustable diameter for limiting the film coil is provided on the support platform 12, wherein the pressure plate 13 presses the insulating film coil or the metal film coil in the material plate through reciprocating motion to flatten the film coil supplied from the outside. The flattened film coil (one group of insulating film coils and two groups of metal film coils) is taken over by the unwinding mechanism 21, which includes three groups of unwinding rollers 210 and a second driving member 211, one of which is used to unwind the insulating film, and the other two groups are used to unwind the metal film at the same time, so as to ensure that the two layers of metal film can effectively clamp the insulating film in the middle.

[0027] The unwound film coil enters the winding mechanism 22, which includes three groups of winding needles 221, three rotating components 222, and a linkage disk 223 for linking the three groups of winding needles 221 to rotate. Among them, one rotating component 222 is used to drive a group of winding needles 221 to wind the film coil unwound by the unwinding mechanism 21, and the linkage disk 223 is precisely rotated by the third driving member 224 to achieve the switching of the three winding needles 221 positions. In order to ensure the precise control of the film tension and position during the winding process, a tensioning mechanism 25 and a film guiding mechanism 26 are installed. The tensioning mechanism 25 realizes uniform tension control of the film through the swing rod and the first tensioning roller 251 in conjunction with the second tensioning roller. The film guiding mechanism 26 uses the movable plate 264 and the first cylinder 265 on the tilting seat 261 to fix the film.

[0028] When in use, the first linear module 262 drives the tilting seat 261 to move back and forth (the first cylinder 265 drives the movable plate 264 to move close to the fixed plate 263 to clamp the film coil), and the film coil clamped by the fixed plate 263 and the movable plate 264 is transferred to between the winding needle 221 and the gluing mechanism 23. At the same time, the tape reel 231 unwinds the double-sided tape onto the transfer gluing roller 235 under the action of the tape clamp 233 and the tape tensioning roller 2311 (the surface of which is provided with a plurality of strip-shaped protrusions to facilitate the picking action of the transfer gluing roller 235). Then the first cutter 232 cuts the double-sided tape. After the connecting rod driving assembly 234 drives the transfer gluing roller 235 to pick up the double-sided tape, it is then pasted between the metal film and the insulating film and between the metal film and the winding needle 221 to fix the three-layer film to the winding needle 221 for easy winding operation.

[0029] After the capacitor element is formed, the gluing mechanism 23 and the linkage disk 223 work together to seal and fix the wound capacitor element, and then the cutting mechanism 24 uses the second cutter 242 to achieve precise cutting of the three-layer film. This cycle is repeated to complete the forming of three groups of capacitor elements. The winding mechanism 22 also includes a stripping assembly, which separates the winding needle 221 from the capacitor element through the second linear module 271 and the stripping handle 272. When in use, the second linear module 271 drives the winding needle 221 to extend forward through the stripping handle 272. At this time, the winding needle 221 is connected to the output end of the rotating assembly 222 through the clutch 2221 for subsequent winding action. When separated, the second linear module 271 drives the winding needle 221 to retreat backward through the stripping handle 272. At this time, the winding needle 221 is separated from the rotating assembly 222 through the clutch 2221. Then, the first material taking robot 28 clamps the capacitor element separated from the winding needle 221 and transfers it to the first material unloading conveyor belt 29. The first material unloading conveyor belt 29 is docked with the material loading conveyor belt 311 of the pin welding device 3 to cooperate with the flip loading robot 312.

[0030] Finally, the pin welding device 3 precisely welds the external conductive pins to the metal film of the capacitor element through the coordinated work of the flip feeding mechanism 31, the pin feeding mechanism 32 and the welding mechanism 33. The operations involved in this part include the conveying of the feeding conveyor belt 311, the rotation and delivery of the flip feeding manipulator 312 (the capacitor elements on the feeding conveyor belt 311 are arranged radially), and the precise welding operation of the second material taking manipulator 333 on the rotating disk 331 and the welding gun 335 on the fixed disk 334.

[0031] Specifically, the flip loading robot 312 includes a flip base 312111, which is telescopically arranged on the welding table 30 via the fifth cylinder 3125. A flip mechanical clamp 3122 is rotatably arranged on the flip base 312111, which is driven to rotate via the first servo motor 3123 and the gear module. The flip mechanical clamp 3122 is driven by the fourth cylinder 3124 to produce a clamping action. When stationary, the flip mechanical clamp 3122 extends into the loading conveyor belt 311. When working, the two cylinder systems and the servo motor system jointly control the flip loading robot 312 to flip the capacitor element in the loading conveyor belt 311 to present a vertical state and transfer it to the second picking robot 333. The second picking robot 333 clamps the capacitor element in the vertical state to facilitate the welding operation of the pins.

[0032] Specifically, the pin loading mechanism 32 includes a pin support frame 321 arranged on the welding table 30, a straightening wheel group 322 rotatably arranged on the pin support frame 321, a pin clamp 323 (driven by the sixth cylinder 3231) reciprocatingly arranged at the end of the straightening wheel group 322, and a pin bending head 324 (driven by the seventh cylinder 3241) reciprocatingly arranged relative to the pin clamp 323, the pin bending head 324 is used to bend and cut the conductive pin transferred by the pin clamp 323, and a pin transfer robot 325 is rotatably arranged above the pin clamp 323 on the pin support frame 321, and a movable spot welder 3341 is also provided on the fixed plate 334, the pin transfer robot 325 is used to transfer the conductive pin bent and cut by the pin bending head 324 to above the capacitor element clamped by the second feeding robot 333, and then the spot welder 3341 spot welds the conductive pin to the capacitor element to facilitate the subsequent soldering process of the welding mechanism 33.

[0033] In the working process of this equipment, the film coil is first pre-treated by the film pressing device 1 to ensure that the film is flat and wrinkle-free. The treated film is accurately fed into the winding mechanism 22 through the unwinding mechanism 21, in which the rotating component 222 operates the winding needle 221 according to the set speed and rotation angle according to the scheduling of the control system to ensure that the film is wound and formed in the correct way. The tensioning and clamping mechanism during the winding process ensures the tension and position accuracy of the film during winding to avoid deviations. After the capacitor element is formed, the edge sealing and cutting are completed by the gluing and cutting mechanism 24 to ensure the structural integrity and size specifications of the capacitor element. Finally, the pin welding device 3 completes the production of the capacitor element, and the conductive pins are fixed to the capacitor element through a precise welding process to ensure the electrical performance of the capacitor.

[0034] Through the 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.

[0035] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The content of this specification should not be understood as limiting the present invention.
