[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] In one embodiment, Figure 1-Figure 4As shown, an adjustable capacitor film production coating device includes a coating machine 100, an exhaust box 300, a vacuum pump 101, a first exhaust pipe 102 and a second exhaust pipe 103. The coating machine 100 is provided with an exhaust box 300 on the left side, and the vacuum pump 101 is provided on the left side of the exhaust box 300. The coating machine 100 is connected to the exhaust box 300 through the first exhaust pipe 102, and the exhaust box 300 is connected to the vacuum pump 101 through the second exhaust pipe 103. The coating machine is provided with a coating component 200, and the exhaust box 300 is provided with a cleaning filter component 400;

[0025] When in use, the capacitor film to be coated is placed in the coating machine 100, and then the vacuum pump 101 is started to evacuate the coating machine 100 for vacuum treatment, and the coating component 200 is started for heating and evaporation. After the vacuuming is completed, the vacuum pump 101 is turned off, and the coating component 200 starts further coating work. After the coating work is completed, the cleaning and filtering component 400 can be started to process the impurities filtered during the vacuuming process. After the processing is completed, the cleaning and filtering component 400 is turned off. Finally, when the temperature in the coating machine 100 drops, the capacitor film can be taken out to complete the coating.

[0026] In one embodiment, Figure 2 and Figure 3 As shown, the coating assembly 200 includes a coating box 201, a threaded rod 202, a movable block 203, a fixed knob 204, an opening 205, a shield 206, a slide bar 207, a threaded hole 208 and a slide hole 209, the threaded rod 202 is arranged in the coating machine 100, the slide bar 207 is arranged at the lower side of the threaded rod 202, the movable block 203 is provided with a threaded hole 208 and a slide hole 209, the positions of the threaded hole 208 and the slide hole 209 correspond to the positions of the threaded rod 202 and the slide bar 207, the movable block 203 is sleeved on the threaded rod 202 and the slide bar 207, the coating box 201 is arranged on the movable block 203, the opening 205 is arranged in the grooves at the front and rear ends of the coating box 201, two shields 206 are slidably connected to the grooves, and two fixed knobs 204 are screwed on the front and rear ends of the shield 206;

[0027] When in use, the capacitor film to be coated is placed in the coating machine 100, and then the position of the baffle 206 is adjusted according to the size of the capacitor film, and then the coating box 201 is started to start heating and evaporating the molten metal in the coating box 201, and then the threaded rod 202 is started to work, and the threaded rod 202 is driven by the output end of the bidirectional rotating motor to rotate, so that the movable block 203 mounted on the threaded rod 202 will move back and forth on the threaded rod 202 and the slide bar 207. The slide bar 207 is designed to enable the movable block 203 to move left and right on the threaded rod 202 when the threaded rod 202 rotates, and will not be rotated by the rotation of the threaded rod 202. At the same time, the coating box 201 on the movable block 203 will also be driven to move back and forth on the threaded rod 202 and the slide bar 207, so that the molten metal in the coating box 201 evaporates onto the capacitor film to be coated, thereby completing the coating and making the coating amount on the capacitor film uniform.

[0028] In one embodiment, Figure 3 As shown, the openings 205 are evenly arranged in the groove, and threads matching the fixing knobs 204 are arranged in the openings 205. The two fixing knobs 204 are close to the coating box 201 and penetrate the front and rear ends of the shielding plate 206 and are connected to the openings 205.

[0029] When in use, before coating, the position of the baffle 206 can be adjusted according to the size of the capacitor film to be coated, the fixing knob 204 can be loosened outward, and then the baffle 206 can be pushed or pulled to move the baffle 206 in the groove. When the baffle 206 moves to the appropriate position, the fixing knob 204 is tightened inward, and the fixing knob 204 will cooperate with the thread in the opening 205 to fix the baffle 206, so that the coating box 201 can perform coating operations on capacitor films of different sizes.

[0030] In one embodiment, Figure 2 and Figure 4 As shown, the air extraction box 300 includes a spiral tube 301, a heat sink 302, a fan 303, a dust cover 304, a baffle 305 and a cleaning filter assembly 400. A dust cover 304 is provided at the top of the air extraction box 300, and a baffle 305 is provided in the middle of the air extraction box 300. The upper end of the baffle 305 is provided with a spiral tube 301, the upper end of the spiral tube 301 is connected to the second air extraction pipe 103, and the lower end passes through the baffle 305. Two heat sinks 302 are provided on the spiral tube 301, and a fan 303 is provided at the rear end of the spiral tube 301. The lower end of the baffle 305 is provided with a cleaning filter assembly 400;

[0031] When in use, before coating begins, it is necessary to start the vacuum pump 101 to evacuate the coating machine 100, and at the same time start the vacuum pump 101 and the fan 303. The air in the coating machine 100 passes through the first exhaust pipe 102 and enters the exhaust box 300. After passing through the cleaning filter assembly 400, the air enters the spiral tube 301 through the baffle 305. At this time, the high-temperature gas in the spiral tube 301 will be cooled by the fan 303 and the heat sink 302. At the same time, the high-temperature gas in the exhaust box 300 is heat exchanged with the gas outside the box through the through holes around the exhaust box 300 to prevent the high-temperature gas from entering the vacuum pump 101 and affecting the working efficiency of the vacuum pump 101. The dust cover 304 on the top of the exhaust box 300 can prevent dust from entering the exhaust box 300.

[0032] In one embodiment, Figure 2 and Figure 4 As shown, the cleaning filter assembly 400 includes a sponge brush 401, a filter screen 402, filter holes 403, a cleaning threaded rod 404 and a cleaning threaded block 405. The filter screen 402 is arranged on the lower side of the baffle 305, and a plurality of filter holes 403 are evenly arranged on the filter screen 402. A sponge brush 401 is also arranged on the lower end surface of the filter screen 402. The lower end of the sponge brush 401 is connected to the cleaning threaded block 405, and the cleaning threaded block 405 is sleeved on the cleaning threaded rod 404.

[0033] During use, when performing vacuum treatment, the gas in the coating machine 100 enters the vacuum box 300 through the first vacuum pipe 103, and then the air will move upward through the filter 402. The filter holes 403 on the surface of the filter 402 will filter the impurities in the air, so that the impurities remain on one side of the filter 402, and the filtered gas moves upward through the filter 402. After the vacuum is completed, the bidirectional rotating motor can be started to make the cleaning threaded rod 404 start to rotate, driving the cleaning threaded block 405 on the cleaning threaded rod 404 to move on the cleaning threaded rod 404, thereby driving the sponge brush 401 to move on the surface of the filter 402, thereby cleaning the impurities on the filter 402 and the filter holes 403, and preventing impurities from clogging the filter 402 and affecting the normal operation of the equipment.

[0034] In one embodiment, Figure 2 As shown, the spiral tube 301 and the heat sink 302 are both made of copper;

[0035] When in use, copper material can dissipate heat better, so the spiral tube 301 and the heat sink 302 are made of copper material to cool the high-temperature gas more significantly, and the setting of the spiral tube 301 is to allow the high-temperature gas to stay in the spiral tube 301 for a longer time, thereby improving the cooling effect.

[0036] In one embodiment, Figure 2 and Figure 4As shown, the sponge brush 401 is of equal length to the filter screen 402;

[0037] When in use, the sponge brush 401 and the filter screen 402 are of equal length, so that the sponge brush 401 can better clean the impurities on the filter screen 402 driven by the cleaning threaded rod 404 and the cleaning threaded block 405, thereby improving the cleaning effect of the sponge brush 401.

[0038] In one embodiment, Figure 2 As shown, the coating machine 100 and the vacuum box 300 are both provided with motors on the outside, and the motor on the outside of the coating machine 100 and the motor on the bottom of the vacuum box 300 are both bidirectional rotating motors;

[0039] When in use, the threaded rod 202 and the cleaning threaded rod 404 can be rotated forward and reversely by starting the bidirectional rotation motor, thereby realizing the back and forth movement of the movable block 203 and the cleaning threaded block 405.

[0040] The working principle of the utility model is: when in use, the capacitor film to be coated is placed in the coating machine 100, and then the coating box 201 is started to heat and evaporate the molten metal in the coating box 201, and at the same time, the vacuum pump 101 is started to evacuate the coating machine 100, and the gas enters the cleaning filter component 400 through the first exhaust pipe 102, and the gas will move upward to the filter screen 402. The filter holes 403 on the filter screen 402 will filter the gas and filter the impurities contained in the gas on the filter screen 402. The filtered gas will enter the spiral tube 301 through the baffle 305, and then the fan 303 is started to cool down the high-temperature gas in the spiral tube 301. The heat sink 302 on the spiral tube 301 will also be cooled at the same time. The high-temperature gas will exchange heat with the external air through the through holes around the exhaust box 300 to prevent the high-temperature gas from entering the vacuum pump 101 and affecting the vacuum The working efficiency of the air pump 101 is improved, and the cooled gas is discharged from the vacuum pump 101 through the second exhaust pipe 103. After the exhaust work is completed, the bidirectional rotating motor on the outside of the coating machine 100 is started, so that the threaded rod 202 starts to rotate, and the movable block 203 on the threaded rod 202 moves, thereby driving the coating box 201 to move, so that the evaporated molten metal is coated on the capacitor film, and the coating amount can be uniform. After the coating is completed, the coating assembly 200 is closed and the bidirectional rotating motor on the lower side of the exhaust box 300 is started at the same time, so that the cleaning threaded rod 404 starts to rotate, and the cleaning threaded block 405 moves, thereby driving the sponge block 401 to move on the surface of the filter 402, thereby cleaning the impurities on the filter 402 and the filter hole 403, and avoiding impurities clogging the filter 402 and affecting the normal operation of the equipment. Finally, after the temperature in the coating machine 100 drops, the coated capacitor film can be taken out.

[0041] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
