Description

Technical Field

[0001] The present application relates to the field of capacitor processing, particularly to the winding technology of metallized safety film, and specifically to a winding device for metallized safety film. Background Art

[0002] A capacitor is an electronic component used to hold electric charges in the form of an electric field in a circuit to store electrical energy. It generally consists of two conductive plates separated by a layer of non-conductive insulating medium. Industrially, capacitors are usually processed by winding two layers of metallized safety film. The metallized safety film is generally made by plating a layer of low-melting-point metal on the surface of a plastic film with high dielectric constant and good insulation performance. Currently, during the production and processing of capacitors, the winding process of the metallized safety film generally requires manual adhesion of the wound metallized safety film to the core, and the finished wound roll needs to be manually unloaded. The loading and unloading operations are relatively troublesome, and manual operation is prone to damage the metallized safety film. Secondly, since the metal layer of the metallized safety film is a relatively thin metal layer formed by vacuum coating, if a conventional winding device is used, the metal layers will rub against each other during the winding process, easily causing wear of the metal layer, thereby affecting the performance of the capacitor. Moreover, since the thickness of the metallized safety film on the core is constantly increasing during the winding of the conventional winding device and the feeding position is constantly changing, it is easy to cause uneven winding of the metallized safety film, which cannot meet the high-standard requirements for the winding of the metallized safety film and affects the stability of the winding of the metallized safety film. Summary of the Invention

Detailed implementation mode

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will describe the implementation modes of the present invention in detail with reference to the accompanying drawings. However, the embodiments described herein are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0029] As Figure 1 and Figure 5 shown, this embodiment provides a metallized safety film winding device, including a screw 1, a fitting post 2, a fitting rod 3, a film feeding mechanism 4, and a transfer mechanism 5.

[0030] Specifically, as Figure 5As shown, the screw rod 1 is arranged at intervals parallel to the fixed-position first axis and rotates around the first axis. The screw rod 1 rotates around its own central axis. One end of the screw rod 1 is coaxially connected with a limiting column 11. The screw rod 1 is used to carry the shaft core. The screw rod 1 is arranged to move along a second axis perpendicular to the axial direction of the screw rod 1 and to move along a third axis perpendicular to both the axial direction of the screw rod 1 and the second axis. Both the second axis and the third axis follow the screw rod 1 to rotate around the first axis.

[0031] Specifically, as Figure 5 shown, the mating column 2 is in threaded fit with the other end of the screw rod 1. A mating hole 21 is axially formed on the end face of the mating column 2 facing away from the limiting column 11. More specifically, in this example, two mating holes 21 are formed.

[0032] Specifically, as Figure 1 and Figure 7 shown, the mating rod 3 is arranged outside the other end of the screw rod 1. The mating rod 3 is parallel to the axial direction of the screw rod 1 and is arranged to move along its own axial direction. The mating rod 3 is used to extend into the mating hole 21. More specifically, in this example, two mating rods 3 are provided. The spacing between the mating rods 3 matches the spacing between the mating holes 21, so that both mating rods 3 can extend into the mating holes 21.

[0033] Specifically, as Figure 1 and Figure 9 shown, there are two sets of film feeding mechanisms 4. Each set of film feeding mechanisms 4 includes a first conveyor belt 41 and a second conveyor belt 42. The conveying directions of the first conveyor belt 41 and the second conveyor belt 42 are the same and are both parallel to a horizontal direction, and their conveying surfaces are both perpendicular to a vertical direction. The second conveyor belt 42 of the same set of film feeding mechanisms 4 is arranged directly above the first conveyor belt 41 along the vertical direction, and their conveying surfaces are relatively arranged and spaced apart by a predetermined distance. More specifically, the projections of the first conveyor belt 41 and the second conveyor belt 42 of the same set of film feeding mechanisms 4 in the vertical direction coincide, and the conveying surface of the second conveyor belt 42 is located on the lower surface, and the conveying surface of the first conveyor belt 41 is located on the upper surface. One set of film feeding mechanisms 4 is arranged below the other set of film feeding mechanisms 4 along the vertical direction. The film feeding mechanism 4 is used to convey the metallized safety film.

[0034] Specifically, as Figure 1 and Figure 9As shown in the figure, there are two sets of transfer mechanisms 5. Each set of transfer mechanisms 5 includes a lifting plate 51, a transfer plate 52, a suction cup mechanism 53, and an adhesion mechanism 54. The lifting plates 51 are respectively arranged outside one end of the first conveyor belt 41 and are all arranged to move in the vertical direction. The transfer plates 52 are respectively arranged above the second conveyor belt 42 and are arranged to move in the horizontal direction. The lower surface of the transfer plate 52 is provided with lifting plates 55 at intervals and the spacing is adjustable. The suction cup mechanism 53 and the adhesion mechanism 54 are both arranged on the lower surface of the lifting plate 55, and the adhesion mechanism 54 is located in front of the suction cup mechanism 53 in the conveying direction of the first conveyor belt 41. The suction cup mechanism 53 is used to adsorb the metallized safety film, and the adhesion mechanism 54 is used to adhere the metallized safety film to the shaft core. Preferably, the suction cups of the suction cup mechanism 53 can be set to a smaller size and a larger number to avoid damaging the surface of the metallized safety film when adsorbing it; the adhesion mechanism 54 is used to apply hot melt adhesive on the shaft core, so that the end of the metallized safety film can be adhered to the shaft core. The suction cup mechanism 53 and the adhesion mechanism 54 are both prior arts, so no more details will be described here.

[0035] The working process of this equipment will be described below with S1~S5.

[0036] S1. Insert the two metallized safety films to be wound into the two sets of film feeding mechanisms 4 respectively, so that the first conveyor belt 41 and the second conveyor belt 42 are respectively in contact with the surface of the metallized safety film, and drive the metallized safety film to move synchronously through the first conveyor belt 41 and the second conveyor belt 42. During this process, the metallized safety film will not have sliding friction with the first conveyor belt 41 and the second conveyor belt 42, avoiding damage to the surface of the metallized safety film.

[0037] S2. Rotate the screw 1 around the first axis and rotate the screw 1 around its own central axis, so that the mating hole 21 on the mating column 2 is coaxially aligned with the mating rod 3. Move the mating rod 3 so that the mating rod 3 extends into the mating hole 21. At this time, rotate the screw 1 around its own central axis again. At this time, the mating column 2 will not rotate with the screw 1 under the restriction of the mating rod 3, but move outward to the other end of the screw 1 through the thread fit with the screw 1. During this process, it is necessary to move the mating rod 3 synchronously to facilitate the smooth movement of the mating column 2. When the mating column 2 completely disengages from the screw 1, move the mating rod 3 to leave space outside the other end of the screw 1. At this time, a shaft core can be sleeved on the screw 1. After sleeving the shaft core, move the mating rod 3 so that the mating column 2 contacts the other end of the screw 1 again. Rotate the screw 1 and move the mating rod 3 synchronously, and the mating column 2 can enter the screw 1 again and clamp the shaft core together with the limit post 11.

[0038] S3. Rotate the screw rod 1 around the first axis so that the position of the screw rod 1 is slightly lower than the first conveyor belt 41 of one set of film feeding mechanisms 4. Extend the end of the metallized security film through one set of film feeding mechanisms 4. Move up the lifting plate 51 corresponding to one set of film feeding mechanisms 4 so that the upper surface of the lifting plate 51 contacts the metallized security film and flattens the metallized security film on the upper surface of the lifting plate 51. Move the transfer plate 52 corresponding to one set of film feeding mechanisms 4 and adjust the distance between the corresponding lifting plate 55 and the transfer plate 52 so that the suction cup mechanism 53 contacts the end of the metallized security film on the lifting plate 51 and adsorbs it. Move the lifting plate 51 downward. Move the transfer plate 52 until the adhesion mechanism 54 is located above the screw rod 1. During the movement of the transfer plate 52, drive the metallized security film to extend out through one set of film feeding mechanisms 4 at the same or slightly slower speed. Adjust the distance between the lifting plate 55 and the transfer plate 52 so that the adhesion mechanism 54 contacts the core surface on the screw rod 1 and attaches hot melt adhesive. Adjust the distance between the lifting plate 55 and the transfer plate 52 so that the end of the metallized security film adsorbed by the suction cup mechanism 53 adheres to the core. Cancel the adsorption of the end of the metallized security film by the suction cup mechanism 53 and drive the transfer plate 52 and the lifting plate 55 back to their original positions. Rotate the screw rod 1 so that the position of the screw rod 1 is slightly lower than the first conveyor belt 41 of the other set of film feeding mechanisms 4, and repeat the above operations.

[0039] S4. Continuously rotate the screw rod 1 around the first axis, and the film feeding mechanism 4 continuously drives the metallized security film to extend out therefrom. During this process, move the position of the screw rod 1 along the second axis and the third axis so that the incoming roll position of the metallized security film is fixed, avoiding the change of the incoming roll position due to the thickness change of the metallized security film wound on the screw rod 1, and ensuring the stability of winding.

[0040] S5. After the winding is completed, repeat the steps in S2 to remove the wound metallized security film and the core.

[0041] Preferably, as Figure 1 and Figure 2As shown in the figure, the device further includes a first rotating motor 12. The drive shaft of the first rotating motor 12 is arranged coaxially with the first axis and is connected with a first rotating rod 13. The first rotating rod 13 is connected with a second rotating rod 14 parallel to the driving direction of the first rotating motor 12. The second rotating rod 14 is connected with a first mounting bracket 15. A first sliding rod 16 parallel to the second axis is arranged on the first mounting bracket 15. A first sliding block 17 is slidably sleeved on the first sliding rod 16. The first sliding block 17 is connected with a second mounting bracket 18. A second sliding rod 19 parallel to the third axis is arranged on the second mounting bracket 18. A second sliding block 110 is slidably sleeved on the second sliding rod 19. A second rotating motor 111 with a driving direction parallel to the second rotating rod 14 is arranged on the second sliding block 110. The drive shaft of the second rotating motor 111 is coaxially connected with a limiting column 11. The first rotating motor 12 is used to drive the screw 1 to rotate around the first axis. The movement of the first sliding block 17 on the first sliding rod 16 and the sliding of the second sliding block 110 on the second sliding rod 19 are respectively used to drive the screw 1 to move along the second axis and the third axis. The second rotating motor 111 is used to drive the screw 1 to rotate around its own central axis.

[0042] Preferably, as Figures 3 - 5As shown in the figure, a first fixed block 22 is fixed at one end of a first sliding rod 16. The first fixed block 22 is connected to a first rotating seat 23. A first rotating column 24 with an axial direction parallel to that of a second sliding rod 19 is rotatably fitted in the first rotating seat 23. A third rotating motor 25 is provided on the first rotating seat 23. The third rotating motor 25 is coaxially connected to the first rotating column 24. A first mounting rod 26 is vertically connected to the side wall of the first rotating column 24. The first mounting rod 26 is connected to a first rotating frame 27. A first driven column 28 with an axial direction parallel to that of a screw rod 1 is rotatably provided on the first rotating frame 27. The first driven column 28 is rotatably arranged around its own central axis. A second fixed block 29 is fixed at one end of the second sliding rod 19. The second fixed block 29 is connected to a second rotating seat 210. A second rotating column 211 with an axial direction parallel to that of the first sliding rod 16 is rotatably fitted in the second rotating seat 210. A fourth rotating motor 212 is provided on the second rotating seat 210. The fourth rotating motor 212 is coaxially connected to the second rotating column 211. A second mounting rod 213 is vertically connected to the side wall of the second rotating column 211. The second mounting rod 213 is connected to a second rotating frame 214. A second driven column 215 with an axial direction parallel to that of the screw rod 1 is provided on the second rotating frame 214. Further preferably, during winding, the position of the screw rod 1 is vertically located between the two film feeding mechanisms 4, and the first sliding rod 16 is parallel to the horizontal direction, and the second sliding rod 19 is parallel to the vertical direction. At this time, the first fixed block 22 is located above the first slider 17, and the second fixed block 29 is located on the side of the second slider 110 close to the film feeding mechanism 4. During operation, after the ends of the two metallized safety films are adhered to the core, the first driven column 28 and the second driven column 215 are driven by the third rotating motor 25 and the fourth rotating motor 212 to be parallel to the screw rod 1. During the winding process, the first driven column 28 and the second driven column 215 are always in contact with the metallized safety film at the incoming winding position, further ensuring the stability of winding.

[0043] Preferably, as Figures 3 - 5As shown, a first spring 112 is connected between the other end of the first sliding rod 16 and the first slider 17. The first spring 112 is sleeved on the peripheral side of the first sliding rod 16 and is always in a compressed state. The first fixed block 22 is connected with a first mounting block 113. A first linear cylinder 114 with a driving direction parallel to the first sliding rod 16 is arranged on the first mounting block 113. The first slider 17 is connected with a first abutting seat 115. The driving shaft of the first linear cylinder 114 is used to contact the first abutting seat 115. A second spring 116 is connected between the other end of the second sliding rod 19 and the second slider 110. The second spring 116 is sleeved on the peripheral side of the second sliding rod 19 and is always in a compressed state. The second fixed block 29 is connected with a second mounting block 117. A second linear cylinder 118 with a driving direction parallel to the second sliding rod 19 is arranged on the second mounting block 117. The second slider 110 is connected with a second abutting seat 119. The driving shaft of the second linear cylinder 118 is used to contact the second abutting seat 119. With such a design, during winding, without manual or driving mechanism adjustment, the screw rod 1 can automatically move along the second axis and the third axis according to the thickness of the metallized safety film wound thereon under the cooperation of the first driven column 28, the second driven column 215, and the first spring 112 to complete the position adjustment. The first linear cylinder 114 and the second linear cylinder 118 are used to stabilize the position of the screw rod 1 when installing the core, adhering the end of the metallized safety film to the core, and discharging the finished roll.

[0044] Preferably, as Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 shown, a set of first infrared ranging mechanisms 120 are arranged on the first slider 17 and the first fixed block 22, and a set of second infrared ranging mechanisms 121 are arranged on the second slider 110 and the second fixed block 29. Both the first infrared ranging mechanisms 120 and the second infrared ranging mechanisms 121 are used to monitor the thickness of the metallized safety film wound on the core in real time. Since the running speed of the film feeding mechanism 4 is constant, if the screw rod 1 maintains the same rotation speed for winding, the incoming winding speed of the metallized safety film will become higher and higher as the thickness of the metallized safety film on the screw rod 1 increases, which easily causes the running speed of the film feeding mechanism 4 to be unable to keep up with the incoming winding speed of the metallized safety film. By monitoring the thickness of the metallized safety film wound on the core in real time, the rotation speed of the screw rod 1 can be adjusted in time according to the monitored thickness to keep the incoming winding speed stable.

[0045] Preferably, as Figure 6 and Figure 7As shown in the figure, the mating rod 3 is connected to the same moving plate 31.
