[0026] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0028] See also Figures 1 to 3The utility model discloses a device for counting the self-healing points of a capacitor core, comprising: a workbench 10, a first driving component, a light emitting component 30 and an image acquisition component 20. At least two rotatable connecting rollers 11 are arranged on the workbench 10, and the at least two connecting rollers 11 are arranged at intervals and then used to wind the core film. The first driving component can be connected to at least one of the connecting rollers 11 to drive one of the connecting rollers 11 to rotate, and the connecting roller 11 can guide the core film to be wound when rotating, and a detection interval for guiding the core film to be in a horizontally unfolded state is formed between the two connecting rollers 11. The light emitting component 30 is located at the bottom of the workbench 10 and is used to emit light to the detection interval. Finally, the image acquisition component 20 is installed above the workbench 10 and is used to collect the image of the core film in the detection interval.

[0029] On the basis of the above structure, during assembly, the connecting roller 11 can be first rotatably installed on the workbench 10. Specifically, a through hole can be set on the workbench 10 to pass the connecting roller 11 or it can be pivoted to the workbench 10 through a rotating shaft, and the first driving component is connected to one of the connecting rollers 11, and then the two ends of the core film are respectively wound on the top two connecting rollers 11. Then, when the first driving component is turned on, the first driving component can drive one of the connecting rollers 11 to rotate, and the core film can also rotate during the rotation of one of the connecting rollers 11, so that it can be stretched to a horizontally expanded state. At this time, the core film in a horizontally expanded state between the two connecting rollers 11 forms a detection interval, and then the light-emitting component 30 under the workbench 10 emits light to illuminate the detection interval, so that the image acquisition component 20 can collect image data of the core film in the detection interval.

[0030] Specifically, the light emitting component 30 can be arranged under the workbench 10 and between the two connecting rollers 11, and the light it emits can illuminate the core film at the detection interval. In this way, the self-healing points on the core film can be clearly presented. Then, when the image acquisition component 20 is turned on, it can clearly record or photograph the number of self-healing points on the core film at the detection interval, and then transmit the collected image data to the comprehensive analysis and processing device 40 at the back end. Statistical analysis is performed through its built-in image recognition algorithm, which can effectively reduce the time for manual statistics of self-healing points and greatly improve the statistical efficiency of self-healing points.

[0031] It should be noted that the connecting roller 11 in the present embodiment can be formed by a cylindrical roller or a rotating shaft. When assembled, it can be directly rotatably inserted on the workbench 10 along the left and right directions of the workbench 10 and be on the same horizontal line, so that when it rotates, the core film can be in a horizontally unfolded state, which is convenient for the image acquisition component 20 to record the self-healing points; of course, it can also be rotatably pivoted on the workbench 10 through a bearing seat or other connecting seat;

[0032] The specific number of connecting rollers 11 can be set to three, four or more according to the length or number of the core film. When there are multiple connecting rollers 11, a core film detection interval is formed between each two adjacent connecting rollers 11, and a light-emitting component 30 and an image acquisition component 20 can be correspondingly arranged above and below each detection interval to simultaneously collect multiple sets of data. The specific design can be based on actual needs.

[0033] In addition, the light emitting component 30 in the present invention is a lamp, which can be an LED lamp, an incandescent lamp, a fluorescent lamp or an energy-saving lamp, etc. It can be installed between two adjacent connecting rollers 11 and located above or below the detection interval to clearly illuminate the core film of the detection interval.

[0034] Similarly, the image acquisition component 20 is an image acquisition device or an image acquisition instrument, which is located between two adjacent connecting rollers 11 and above or below the detection interval. It can be hoisted or above or below the workbench 10 through a bracket and arranged opposite to the lamp. It uses a built-in camera to shoot the core film of the detection interval, and then can count the number of self-healing points on the core film through a built-in recognition algorithm, without the need for human eye recognition, and has high statistical efficiency;

[0035] Of course, the image acquisition component 20 can also be just a single camera or a still camera with a photo-taking function. When assembled, it can be connected to the comprehensive analysis and processing device 40 (such as a computer) at the back end by wires, and then a recognition algorithm can be built into the comprehensive analysis and processing device 40. During specific operation, the photos of the core film taken at each detection interval can be transmitted to the comprehensive analysis and processing device, and then the number of self-healing points on the core film can be analyzed through the built-in recognition algorithm. The specific structure of the image acquisition component is prior art, and its structure and working principle do not belong to the technical content to be protected by this application, so they will not be elaborated.

[0036] Furthermore, it also includes at least two tensioning rollers 12, and the at least two tensioning rollers 12 and the at least two connecting rollers 11 are alternately distributed on the workbench 10 from bottom to top, and wind the core film in sequence.

[0037] During specific assembly, at least two tensioning rollers 12 are also installed on the workbench 10. At least the tensioning roller 12 can be arranged along the vertical direction of the workbench 10, and can be arranged perpendicularly or inclined to the assembly direction of the at least two connecting rollers 11, so that the at least two tensioning rollers 12 and the at least two connecting rollers 11 can be distributed on the workbench 10 from bottom to top or from top at least in sequence and staggered. In this way, after the core film is wound around at least two tensioning rollers 12 and at least two connecting rollers 11 in sequence, when the core film is wound too loosely or too tightly, the tension of the core film can be adjusted by rotating the tensioning roller 12 to prevent the core from loosening or being wound too tightly to affect use.

[0038] It should be noted that the number of the tensioning rollers 12 can be set according to the number of the connecting rollers 11 , and specifically can be two, three, four or more.

[0039] Furthermore, a positioning roller 14 and a driving roller 13 are provided on the workbench 10. The positioning roller 14 is installed at one end of the workbench 10, and the driving roller 13 is installed at the other end of the workbench 10. At least two tensioning rollers 12 and at least two connecting rollers 11 are located between the positioning roller 14 and the driving roller 13. The second driving component is connected to the driving roller 13 and is used to drive the driving roller 13 to rotate. The driving roller 13 is used to drive the core film to wind when rotating.

[0040] Specifically, if only a connecting roller 11 and a tensioning roller 12 are provided on the workbench 10, since the connecting roller 11 and the tensioning roller 12 are both flexible and rotatable, the core film is likely to fall off due to the rotation of the connecting roller 11 and the tensioning roller 12 during assembly, and is likely to be misaligned or deviated, making assembly inconvenient. Therefore, a positioning roller 14 and a driving roller 13 are also provided in this embodiment. During specific use, the core film can be first wound around the fixed positioning roller 14, and one end of the core film is positioned by the positioning roller 14. Then, the other end is successively wound around the tensioning roller 12 and the connecting roller 11 from bottom to top or from top to bottom, and finally extended to the driving roller 13. In this way, when the driving roller 13 is started, the rotation of the driving roller 13 can drive the core film to rotate together, because the other end of the core film is always supported and fixed by the positioning roller 14, so that it is not easy to fall off or loosen, thereby ensuring its continuity and stability during rotation.

[0041] Preferably, the positioning roller 14 may be fixed to the workbench 10 via a connecting member (such as a screw or a bolt), or may be connected to the workbench 10 by a snap-fit ​​connection.

[0042] Furthermore, at least two connecting rollers 11 and at least two tensioning rollers 12 are each provided with a fixing plate 111 , and the plurality of fixing plates 111 are respectively detachably connected to the workbench 10 .

[0043] In this embodiment, at least two connecting rollers 11 and at least two tensioning rollers 12 are provided with a fixing plate 111. During assembly, the at least two connecting rollers 11 and the at least two tensioning rollers 12 can be rotatably inserted into the fixing plate 111 one by one, and then the fixing plate 111 is welded or connected to the workbench 10 using a connecting piece.

[0044] During assembly, a connecting shaft can be set on the fixed plate 111, and connecting holes are preset on the connecting roller 11 and the tensioning roller 12, so that the connecting roller 11 and the tensioning roller 12 can be respectively sleeved on the connecting shaft through the connecting holes, so that both can rotate.

[0045] Preferably, in order to facilitate disassembly, a mounting hole 112 is provided on the fixing plate 111, and a connecting piece is connected to the workbench 10 through the mounting hole 112, so that the fixing plate 111 and the workbench 10 can be detachably connected. In this way, even if the connecting roller 11 or the tensioning roller 12 is worn out later, it is easy to maintain or replace.

[0046] Furthermore, at least two support columns 15 are provided at the bottom of the workbench 10 , the at least two support columns 15 are arranged at intervals, and at least two tensioning rollers 12 are respectively installed on the at least two support columns 15 , and the light emitting component 30 is located between the at least two support columns 15 .

[0047] During assembly, at least two support columns 15 can be welded or glued to the bottom of the workbench 10, and the two support columns 15 can be spaced apart to support the workbench 10. At this time, the interval between the two support columns 15 can form an installation interval, and the light-emitting component 30 can be installed in this installation interval.

[0048] Specifically, at least two tensioning rollers 12 and at least two connecting rollers 11 in this embodiment can be located between two support columns 15, wherein the two tensioning rollers 12 can be installed on the support columns 15 respectively, and the two connecting rollers 11 can be installed on the workbench 10, so that the two tensioning rollers 12 and the two connecting rollers 11 are staggered from top to bottom. Since the two connecting rollers 11 are also arranged between the two support columns 15, the light emitted by the light-emitting component 30 located between the two support columns 15 can be irradiated on the detection interval of the core film formed on the two connecting rollers 11, so that the self-healing points on the core film at the detection interval are more clearly visible, which is convenient for the image acquisition component 20 to record.

[0049] Based on this structure, a mounting bracket 16 is provided on the workbench 10 in this embodiment. Specifically, the mounting bracket 16 can be set at the middle position of the workbench 10 between the two support columns 15, and then the image acquisition component 20 is installed on the mounting bracket 16, so that the image acquisition component 20 can be located above the core film of the detection interval, so as to facilitate the collection of self-healing points.

[0050] Furthermore, the second driving assembly includes a driving motor 50 , which is installed on a side of the workbench 10 away from the driving roller 13 , and a power output end of the driving motor 50 passes through the workbench 10 and is connected to the driving roller 13 .

[0051] Specifically, the second driving component in this embodiment is a driving motor 50. During assembly, the driving motor 50 can be fixed to one side of the workbench 10 through a connecting piece (screws or bolts, etc.), and the power output end of the driving motor 50 (such as a linkage shaft) can pass through the workbench 10 and be connected to the driving roller 13 to drive the driving roller 13 to rotate. Compared with assembling the driving motor 50 and the driving roller 13 on the same side, this method has a more stable connection and is not easy to loosen, and the exterior of the workbench 10 is simpler.

[0052] Preferably, a mounting plate 51 is provided on the driving motor 50. During installation, one side of the mounting plate 51 can be welded to the driving motor 50, and the other side of the mounting plate 51 can be connected to the workbench 10 through a connecting piece, which is convenient for later maintenance and disassembly, and the structure is more practical.

[0053] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
