[0002] Ceramic capacitors are one of the most widely used electronic components. Ceramic capacitors are also called ceramic capacitors or monolithic capacitors. Ceramic capacitors are capacitors whose dielectric material is ceramic. According to different ceramic materials, they can be divided into low-frequency ceramic capacitors and high-frequency ceramic capacitors; according to the structural form, they can be divided into disc capacitors, tubular capacitors, rectangular capacitors, sheet capacitors, through-hole capacitors, etc. Compared with other capacitors, ceramic capacitors have the advantages of small size, large capacity, good heat resistance, suitable for mass production, and low price.

[0028] See also Figures 1 to 4The embodiment of the present application provides a cutting mechanism, including a conveying structure, a cutting piece 10, an elastic pressing piece 20, a roller piece 50 and a mounting seat 30. The conveying structure is used to convey the film along a first direction a. The conveying structure may include two transmission rollers. The film is wound between the two transmission rollers. The two transmission rollers roll so that the film can be conveyed forward along the first direction a. The mounting seat 30 is arranged above the film. The cutting piece 10 is rotatably connected to one end of the mounting seat 30 close to the film. The roller piece 50 is arranged below the conveying surface of the conveying structure and corresponds to the cutting piece 10.

[0029] The cutting piece 10 includes a cutting end facing the diaphragm and an abutting end away from the diaphragm. The cutting piece 10 includes a cutter 11 arranged at the cutting end and used for cutting the diaphragm. The elastic pressing piece 20 is fixed to the mounting seat 30. The elastic pressing piece 20 is used to elastically abut against the abutting end when the cutter 11 cuts the diaphragm. When the cutter 11 cuts the diaphragm, the diaphragm is pressed between the cutter 11 and the circumferential surface of the roller piece 50.

[0030] The cutting mechanism of the present application is such that when the film is conveyed along the first direction a, the cutter 11 contacts the film, thereby being able to cut the film, and when the cutter 11 cuts the film, the elastic pressing member 20 can elastically abut against the abutting end of the cutting member 10, thereby applying an elastic pressing force to the cutting member 10, so that the cutter 11 can swing at a small angle, so that the cutter 11 always maintains close contact with the surface of the film, thereby improving the cutting effect of the film.

[0031] Preferably, the cutting mechanism includes two cutting pieces 10, the two cutting pieces 10 are spaced apart along the second direction b, and the distance between the two cutting pieces 10 and the film is equal, that is, the heights of the two cutting pieces 10 in the vertical direction are equal, and the second direction b is perpendicular to the first direction a. It can be understood that, taking the film as a reference, the first direction a is the length direction of the film, and the second direction b is the width direction of the film. When the film is transported forward along the first direction a, the two cutting pieces 10 are stationary, and the two cutting pieces 10 do not exceed the two sides of the film in the width direction. Therefore, when the two cutting pieces 10 cut the film, the two cuts extend along the first direction a. When the cutting is completed, the width of the film formed by cutting becomes smaller than the width of the film before cutting.

[0032] In some embodiments, Figure 3 and Figure 4 As shown, the cutting piece 10 also includes a rotating block 12, and the cutter 11 is fixed on the rotating block 12. The rotating block 12 is rotatably connected to the mounting seat 30 through a rotating shaft, and the axial direction of the rotating shaft is parallel to the second direction b, that is, the cutter 11 can swing around the rotating axis within a certain angle range, and the elastic clamping piece 20 elastically abuts against the rotating block 12 when the cutter 11 cuts the membrane, and the abutting end is the end of the rotating block 12 facing the elastic clamping piece 20.

[0033] Furthermore, the cutting mechanism also includes a tension spring 40, a first connecting post 31 is connected to the mounting seat 30, and a second connecting post 121 is connected to the rotating block 12. The first connecting post 31 and the second connecting post 121 are respectively protruded from the side walls of the mounting seat 30 and the rotating block 12, and the first connecting post 31 and the second connecting post 121 are located on the same side, and the first connecting post 31 is located above the second connecting post 121. The two ends of the tension spring 40 are respectively connected to the first connecting post 31 and the second connecting post 121. When the cutting piece 10 cuts the diaphragm, the force required for the cutting piece 10 to cut the diaphragm is small, and only the elastic pressing piece 20 is required to provide The force for pushing the cutting piece 10 is sufficient, but since the cutting piece 10 and the mounting seat 30 are not fixedly connected but rotatably connected, the cutting piece 10 can swing within a certain angle range, so the cutting piece 10 is affected by its own gravity and will also exert a force on the diaphragm, pressing on the diaphragm, resulting in a large pressing force on the diaphragm, affecting the cutting effect, so by arranging a tension spring 40 between the mounting seat 30 and the cutting piece 10, the tension direction of the tension spring 40 is opposite to the gravity direction of the cutting piece 10, so that the tension of the tension spring 40 can offset the gravity of the cutting piece 10, thereby avoiding the gravity of the cutting piece 10 from affecting the cutting. Optionally, the first connecting column 31 and the second connecting column 121 can be directly opposite in the vertical direction, and the first connecting column 31 is located directly above the second connecting column 121, so that the tension spring 40 extends in the vertical direction in a natural state.

[0034] Furthermore, the cutting piece 10 also includes a fixed block 13, a suction nozzle 14 and a negative pressure joint 15. The fixed block 13 is connected to the rotating block 12, the suction nozzle 14 and the negative pressure joint 15 are fixed on the fixed block 13, the suction nozzle 14 and the negative pressure joint 15 are communicated, the suction nozzle 14 is adjacent to the cutter 11 and faces the cutter 11, the negative pressure joint 15 can be connected to a negative pressure device through a connecting pipe, the negative pressure device is used to generate a negative pressure environment, so that the suction nozzle 14 has an adsorption effect, and because the cutter 11 will produce film fragments at the edge of the cutter 11 when cutting the film, the suction nozzle 14 can absorb the film fragments, thereby preventing the film fragments from falling on the film and affecting the subsequent lamination process of the film. This is because the multiple film sheets formed by cutting need to be stacked one by one in the lamination process. If there are film fragments on the surface of the film, the film fragments are located between two adjacent stacked film sheets, which will affect the performance of the final product.

[0035] In some embodiments, the cutting mechanism may further include a dust removal structure, which is adjacent to the mounting seat 30 and is located above the diaphragm, and the dust removal structure is located on the rear side of the mounting seat 30 along the first direction a. After the diaphragm is cut, it flows to the dust removal structure. At this time, the dust removal structure can absorb the dust on the diaphragm, and the dust and film fragments on the diaphragm will affect the subsequent lamination process of the diaphragm. The dust on the diaphragm can be absorbed by the dust removal structure to prevent the dust from affecting the performance of the final product.

[0036] In some embodiments, the elastic clamping member 20 is a low-friction cylinder, and the output end of the low-friction cylinder is connected to a movable joint 21, which can extend toward the diaphragm or retract away from the diaphragm. The movable joint 21 abuts against the abutting end, so the low-friction cylinder can apply an elastic clamping force to the cutting piece 10. The movable joint 21 retracts when it is subjected to the force of the cutting piece 10, and extends to a normal state when it is not subjected to force. The present application sets a low-friction cylinder as the elastic clamping member 20. The low-friction cylinder adopts advanced coating technology, and a layer of low-friction material is coated on the surface, which can significantly reduce friction resistance and heat loss, greatly improve fuel efficiency and power, and reduce pollution emissions, with better economy and environmental protection. In addition, the low-friction cylinder can also reduce noise and vibration. It can be understood that in other possible embodiments, the elastic clamping member 20 can also be a spring or a rubber member, etc., as long as it can elastically abut the abutting end to apply an elastic clamping force to the cutting piece 10. The present application does not limit the specific structure of the elastic clamping member 20.

[0037] In addition, the roller member 50 is arranged below the conveying surface of the conveying structure and corresponds to the cutting member 10. The roller member 50 rotates around a first axis, and the direction of the first axis is parallel to the second direction b. The circumferential surface of the roller member 50 contacts the film. When the cutter 11 cuts the film, the film is pressed between the cutter 11 and the circumferential surface of the roller member 50, thereby making cutting the film more labor-saving.

[0038] Optionally, the cutter 11 of the present application is a circular knife, that is, the cutting edge of the cutter 11 is arc-shaped. The circular knife is more labor-saving to move horizontally, can adapt to large fluctuations and small changes, and is flexible to use. When the cutter 11 cuts the membrane, the cutting edge section of the cutter 11 is tangent to the circumferential surface of the roller member 50.

[0039] Furthermore, the cutting mechanism also includes a bracket 60, a first movable platform 70 and a second movable platform 80. The bracket 60 is arranged horizontally above the conveying surface of the conveying structure. The first movable platform 70 is fixed on the bracket 60. The second movable platform 80 can be movably connected to the first movable platform 70 along the second direction b. The mounting seat 30 can be movably connected to the second movable platform 80 along the third direction c. The third direction c is perpendicular to the first direction a and the second direction b. In the present application, the third direction c is the vertical direction. The operator can adjust the position of the mounting seat 30 through the second movable platform 80. When the film does not need to be cut, the cutting piece 10 can be retracted. The lateral position of the mounting seat 30 can also be finely adjusted through the first movable platform 70, and then locked by a locking member after adjustment.

[0040] The utility model also proposes a processing device, which includes a cutting mechanism. The specific structure of the cutting mechanism refers to the above embodiment. Since the processing equipment adopts all the technical solutions of all the above embodiments, it also has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0041] To sum up, in the cutting mechanism of the present application, when the film is conveyed along the first direction a, the cutter 11 contacts the film, thereby being able to cut the film, and when the cutter 11 cuts the film, the elastic pressing member 20 can elastically abut against the abutting end of the cutting member 10, thereby applying an elastic pressing force to the cutting member 10, so that the cutter 11 can swing at a small angle, so that the cutter 11 always maintains close contact with the surface of the film, thereby improving the cutting effect of the film.

[0042] The above are only optional embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations.
