[0046] Example 1

[0047] like Figure 1-3 and Figure 6 As shown, the present invention provides a technical solution: a capacitor film double-sided corona treatment device, comprising:

[0048] S1. Film assembly: Assemble the capacitor film to be corona treated at one end of the treatment equipment, and fix the film at the other end of the treatment equipment after passing through the roller 2010b inside the treatment equipment;

[0049] S2, single-side processing: start the equipment, pull the film to move by winding at one end of the equipment, and complete the single-side processing of the film when passing through the corona assembly 2011 inside the processing equipment;

[0050] S3, secondary treatment: after the single side of the film is treated, the film is removed and turned over to be assembled again, and the equipment is started to perform corona treatment on the other side of the film;

[0051] When the capacitor film is subjected to corona treatment in the above manner, it also specifically involves a double-sided corona treatment device for the capacitor film, including a shell mechanism 100 and a treatment mechanism 200 .

[0052] Further: A double-sided corona treatment device for capacitor film, comprising:

[0053] The shell mechanism 100 includes a processing shell 101, a roller bracket 102 arranged on both sides of the processing shell 101, and two film inlets 103 opened on both sides of the processing shell 101; and a processing mechanism 200 includes an air compressor 201, a filter box 202 connected to the exhaust end of the air compressor 201, and a third duct 206 connected to the air inlet end of the air compressor 201, wherein the filter box 202 is respectively connected to the first duct 203 and the second duct 204, and the third duct 206 is connected to the grounding component 207.

[0054] In detail, at least a part of the processing mechanism 200 is arranged in the housing mechanism 100, including an air compressor 201, a filter box 202, a first conduit 203, a third conduit 206 and a grounding assembly 207, wherein the air inlet end of the air compressor 201 is connected to the third conduit 206 and the grounding assembly 207 in sequence, the air exhaust end of the air compressor 201 is connected to the filter box 202 and the first conduit 203, and the other end of the first conduit 203 is provided with a cleaning assembly 205, and the cleaning assembly 205 is provided with a plurality of air holes 205b-2. The processing mechanism 200 may also include a second conduit 204, which is connected to the middle part of the first conduit 203 through a three-way valve, and the other end of the second conduit 204 is provided with another cleaning assembly 205. Preferably, the cleaning assembly 205 connected to the first conduit 203 and the cleaning assembly 205 connected to the second conduit 204 have the same structure and are arranged roughly in parallel.

[0055] In this embodiment, most of the structures of the processing mechanism 200 are arranged in the shell mechanism 100. In order to facilitate the mechanism setting and miniaturization, the undivided conduit is arranged outside the shell mechanism 100. By setting the cleaning component 205, the air compressor 201 and the processing shell 101, when the film is subjected to corona treatment, the press machine needs to be started so that the press machine extracts the gas in the first conduit 203 and the second conduit 204 during operation, so that the air inside the two cleaning components 205 connected to the first conduit 203 and the second conduit 204 is quickly lost. Since the surface of the connecting tube 205b-1 is provided with a plurality of air inlet holes 205b-2, the film will be adsorbed by the surface of the connecting tube 205b-1 during the movement. On the one hand, the tightness of the contact between the film and the connecting tube 205b-1 during the movement can be ensured, and the film can be prevented from being offset or folded internally. On the other hand, the surface of the film to be processed can be cleaned by extracting gas, which reduces the steps required for processing the film, ensures the quality of the film after processing, and improves the efficiency of the processing equipment for film processing.

[0056] Example 2

[0057] Combined with Figure 2 and attached Figure 4 The lower parts of the air compressor 201 and the filter box 202 are fixedly connected to the lower part of the inner wall of the treatment shell 101. The grounding assembly 207 is fixedly connected to the treatment shell 101. A through hole 104 is provided at the lower part of the treatment shell 101. The position of the grounding assembly 207 corresponds to the position of the through hole 104. A roller assembly 2010 and a corona assembly 2011 are provided in the treatment shell 101. Two branch pipes 208 are provided outside the third conduit 206, and the two branch pipes 208 are connected to the same drying assembly 209.

[0059] In the present embodiment: since the press will pass the extracted gas into the press through the filter box 202 during the extraction process, the processing equipment can simultaneously achieve the effect of air filtration while cleaning the film. On the one hand, it reduces the pollution of the processing equipment to the outside air, and on the other hand, it can effectively avoid the accumulation of impurities in the press and cause blockage, thereby ensuring the service life of the processing equipment.

[0061] Combined with Figure 5 and attached Figure 6 , the cleaning assembly 205 includes two mounting cylinders 205a and a connector 205b located between the two mounting cylinders 205a, two fixing brackets 205c are fixedly connected in the connector 205b, and the first bearing 205d is sleeved in the two fixing brackets 205c; wherein the mounting cylinder 205a on one side is connected to the air compressor 201, and the mounting cylinder 205a on the other side is fixedly connected to the processing shell 101. It can be understood that in a preferred embodiment, the processing mechanism 200 includes at least two cleaning assemblies 205 with the same structure, wherein the mounting cylinder 205a of one cleaning assembly 205 is connected to the first conduit 203, and the mounting cylinder 205a of the other cleaning assembly 205 is connected to the second conduit 204. Preferably, the first conduit 203 and the second conduit 204 are arranged in parallel at some positions, so that the two cleaning assemblies 205 can be arranged roughly in parallel.

[0062] In detail: the cleaning component 205 includes a mounting cylinder 205a, the number of the mounting cylinders 205a is two, and the opposite sides of the two mounting cylinders 205a are connected to the same connector 205b, two fixed brackets 205c are fixedly connected inside the connector 205b, and the two fixed brackets 205c are both sleeved with a first bearing 205d, the other side of the mounting cylinder 205a is connected to the first conduit 203, the mounting cylinder 205a is fixedly connected to the outside of the processing shell 101, a rotating shaft 205e is arranged in the connector 205b, both ends of the rotating shaft 205e are respectively clamped in the two first bearings 205d, two groups of fan blades 205f are fixedly connected to the outside of the rotating shaft 205e, and a plurality of scrapers 205g are fixedly connected to the outside of the rotating shaft 205e, and the surface of the scraper 205g is preferably smooth. The connector 205b includes a connecting tube 205b-1, a plurality of air inlet holes 205b-2 are provided outside the connecting tube 205b-1, two ends of the connecting tube 205b-1 are respectively connected to the two mounting tubes 205a, a fixing bracket 205c is fixedly connected in the connecting tube 205b-1, and a scraper 205g overlaps the connecting tube 205b-1. The scraper 205g can clean the surface of the film and further improve the quality of the film after processing.

[0063] The grounding component 207 includes a sealing cylinder 207a, in which a piston plate 207b is arranged, a connecting rod 207c is fixedly connected to the bottom of the piston plate 207b, a spring 207d is fixedly connected to the sealing cylinder 207a, and both ends of the spring 207d are respectively fixedly connected to the top of the piston plate 207b and the top of the inner wall of the sealing cylinder 207a, the sealing cylinder 207a is fixedly connected to the inner wall of the processing shell 101, the position and size of the connecting rod 207c correspond to the position and size of the through hole 104, the drying component 209 includes an exhaust hood 209a, a plurality of exhaust holes 209b are opened above the exhaust hood 209a, and the bottom of the exhaust hood 209a is connected to the branch pipe 208, and the roller assembly 2010 includes two second bearings 2010a, and the same roller 2010b is sleeved in the two second bearings 2010a, and the second bearings 2010a are clamped in the processing shell 101.

[0064] In this embodiment: when the press machine extracts gas, the press machine will synchronously discharge the extracted gas into the processing shell 101, and part of the gas will be discharged into the grounding component 207 through the third conduit 206, so that the pressure in the sealing cylinder 207a will increase rapidly. At this time, the piston plate 207b will push the connecting rod 207c to move downward during the pressure process, so that the connecting rod 207c gradually passes through the through hole 104 and contacts the ground. Since the sealing cylinder 207a is in contact with the processing shell 101 and the sealing cylinder 207a is in contact with the ground through the connecting rod 207c, the processing equipment can ensure the overall stability of the processing equipment during operation through the connecting rod 207c. At the same time, the static electricity generated during the operation of the processing equipment can be transferred to the underground to achieve static electricity drainage, avoid a large amount of static electricity accumulation and affect the processing effect of the processing equipment on the film, and ensure the service life of the processing equipment.

[0065] The working principle of the present invention is as follows: when in use, the film material to be processed needs to be placed in the roller bracket, the roller bracket is disassembled, and the rolled film material is installed between the roller brackets, and then the roller bracket is installed and fixed again, at this time, the processing shell is opened, and one end of the rolled roller is passed through the film inlet and the roller located below, and the top of the film is contacted with the bottom of the first connecting cylinder on the left and overlapped on the top of the second roller on the left, and at this time, the film continues to overlap under the second connecting cylinder on the left and passes through the corona assembly in the processing shell. Similarly, the film needs to contact with the right-side connecting cylinder and the roller according to the above-mentioned connection method to complete the assembly, and the film at this time is located directly below the corona assembly and directly above the exhaust hood;

[0066] When the treatment equipment is in operation, the roller bracket on one side will be connected to the external driver, so that the driver will drive the reel installed in the roller bracket to rotate during the rotation process. At this time, the reel will pull the film, so that the film gradually moves between the connecting drum and the roller, and during the movement, the corona component will have a corona treatment effect on the upper side of the film. After the processing is completed, the film needs to be disassembled and the film processing direction is turned over to achieve the effect of corona treatment on both sides.

[0067] When the film is subjected to corona treatment, the press machine needs to be started so that the press machine extracts the gas in the first conduit and the second conduit during operation, so that the air in the two cleaning components connected to the first conduit and the second conduit is quickly lost. Since a plurality of air inlet holes are provided on the surface of the connecting tube, the film is adsorbed by the surface of the connecting tube during movement.

[0068] When the press is extracting gas, the press will simultaneously discharge the extracted gas into the processing shell, and part of the gas will be discharged into the grounding component through the third conduit, causing the pressure in the sealing cylinder to increase rapidly. At this time, the piston plate will push the connecting rod downward during the pressure process, causing the connecting rod to gradually pass through the through hole and contact the ground. Since the sealing cylinder is in contact with the processing shell, the sealing cylinder can be in contact with the ground through the connecting rod.

[0069] Specifically, when in use, the film material to be processed needs to be placed in the roller bracket 102, the roller bracket 102 is disassembled, and the rolled film material is installed between the roller brackets 102, and then the roller bracket 102 is installed and fixed again, at this time, the processing shell 101 is opened, and one end of the rolled roller 2010b is passed through the film inlet 103 and the roller 2010b located below, and the top of the film is contacted with the bottom of the first connecting cylinder 205b-1 on the left and overlapped on the top of the second roller 2010b on the left. At this time, the film continues to be overlapped under the second connecting cylinder 205b-1 on the left and passes through the corona assembly 2011 in the processing shell 101. Similarly, the film needs to contact with the right-side connecting cylinder 205b-1 and the roller 2010b according to the above-mentioned connection method to complete the assembly, and the film at this time is located directly below the corona assembly 2011 and directly above the exhaust hood 209a;

[0070] When the treatment equipment is in operation, the roller bracket 102 on one side will be connected to the external driver, so that the driver drives the reel installed in the roller bracket 102 to rotate during the rotation process. At this time, the reel will pull the film, so that the film gradually moves between the connecting cylinder 205b-1 and the roller 2010b, and during the movement, the corona component 2011 will have a corona treatment effect on the upper side of the film, and after the processing is completed, the film needs to be disassembled and the film processing direction is turned over to achieve the effect of corona treatment on both sides;

[0071] When the film is subjected to corona treatment, the press machine needs to be started so that the press machine can extract the gas in the first conduit 203 and the second conduit 204 during operation, so that the air in the two cleaning components 205 connected to the first conduit 203 and the second conduit 204 can be quickly lost. Since a plurality of air inlet holes 205b-2 are provided on the surface of the connecting tube 205b-1, the film can be adsorbed by the surface of the connecting tube 205b-1 during movement.

[0072] When the press machine extracts gas, the press machine will simultaneously discharge the extracted gas into the processing shell 101, and part of the gas will be discharged into the grounding component 207 through the third conduit 206, so that the pressure in the sealing cylinder 207a will increase rapidly. At this time, the piston plate 207b will push the connecting rod 207c downward during the pressure process, so that the connecting rod 207c gradually passes through the through hole 104 and contacts the ground. Since the sealing cylinder 207a is in contact with the processing shell 101, the sealing cylinder 207a can be in contact with the ground through the connecting rod 207c.
