Description

Technical Field

[0001] The present invention relates to the technical field of material corrosion resistance detection, and in particular to a corrosion resistance detection device and a detection method based on corrosion foil. Background Art

[0002] The corrosion resistance testing equipment of corrosion foil is mainly used to evaluate the corrosion resistance of corrosion foil used in aluminum electrolytic capacitors under conditions such as electrolyte, moisture, acid and alkali environment.

[0003] Referring to Chinese Patent Publication No. CN120142138A, a corrosion resistance detection device and detection method for corrosion foil processing includes a detection box, an exhaust mechanism is provided at the upper end of the detection box, an ultraviolet lamp is provided on the top of the inner wall of the detection box, and a traction mechanism is provided on one side of the detection box. The atomized corrosion liquid in the present invention is closer to the corrosive media in the natural atmosphere, such as acid rain and salt spray, and can more realistically simulate complex corrosion environments. The synergistic effect of light, humidity, and corrosion liquid can be used to study the superposition effect of various corrosion mechanisms, such as photo-oxidation corrosion and wet heat corrosion, which is close to the complex scenarios in actual applications. By comparing the corrosion rate under conditions with and without light, the promoting effect of ultraviolet rays on material corrosion, such as photocatalytic oxidation, can be clarified. By comparing the corrosion foil on the corrosion swing mechanism and the corrosion diffusion mechanism, the influence of different humidity levels on corrosion types such as pitting and crevice corrosion can be analyzed.

[0004] Different types of corrosion foils require different treatment times in salt spray. Usually, only the same type of corrosion foil can be subjected to concentrated salt spray treatment at a time, and multiple types of corrosion foils cannot be subjected to salt spray treatment at the same time. The salt spray treatment time of some corrosion foils is long, and there is sufficient space in the salt spray box, while the rest of the space is idle, which is a waste. Other test objects should be added or replaced without affecting the salt spray concentration and temperature in the box. In addition, it is difficult to turn the corrosion foil over during the inspection process, and it is not easy to complete the corrosion treatment of multiple sides of the corrosion foil.

[0013] A corrosion resistance detection method for corrosion foil includes corrosion resistance detection equipment based on corrosion foil. A channel is opened on a box body so that materials can enter and exit the box body through the channel.

The wind pressure in the cylinder increases, and the wind cover moves toward the axis of the air box with the moving rod, moving plate, and dehumidification plate. The dehumidification plate squeezes the material and wraps the material to absorb the liquid on the surface of the material.

[0014] Beneficial Effects: This invention provides a corrosion-resistant testing device and method based on corrosion foil. Compared with existing technologies, it has the following advantages: 1. Materials move in and out of the box along with the material holding plate. The ends of the movement path serve as limit points, facilitating the sealing and rotation of the material holding plate. After rotation, the material holding plate adapts to the adaptive cleaning device, allowing the material to elastically contact the circumferential dehumidification plates, allowing for simultaneous material removal and cleaning, facilitating material replacement.

[0015] 2. By constructing a channel and matching sealing components and material exchange devices, the treated materials can be replaced in a targeted manner. This allows materials with different salt spray treatment times to be processed in the same batch, and allows materials to be removed after the salt spray treatment time reaches a certain point, while minimizing the impact on other materials still undergoing salt spray treatment. This system has wide adaptability. When it is necessary to perform salt spray treatment on the opposite side of the material, the material can be quickly removed and the channel sealed. The channel cross-section is small, the channel open time is short, and the impact of the channel opening is reduced.

[0016] 3. The material is turned over by its own gravity, so that the liquid in the concave part of the material can flow out as much as possible. Then, through elastic plasticity, the dehumidifying plate is pressed against the material under the action of extrusion.

The middle parts of both sides of the material placement plate 33 near one end of the box body 11 are connected to the slide 39 through the rod 38. The slide 39 is slidably connected to the outer guide rail 34. The other end of the guide tube 31 is connected to the rotating plate 32, which is adapted to the slide 39. The material placement plate 33 is connected to the plug 36 through the socket 35.

[0035] A top groove 17 is provided on the top of the box body 11, and the bottom of the top groove 17 is connected to the top of the sealing groove 62. A first hydraulic cylinder 13 is provided above the box body 11, and the telescopic end of the first hydraulic cylinder 13 is connected to the sealing plate 14. The bottom end of the sealing plate 14 passes through the top groove 17 and is plugged into the sealing groove 62. The sealing plate 14 is used to move in the vertical direction and control the opening and closing of the sealing groove 62 under the drive of the telescopic end of the liquid oxygen cylinder. A stepper motor 21 and a fan 24 are provided in the outer box 12. The fixed end of the stepper motor 21 is connected to the top wall of the outer box 12, and the rotating end of the stepper motor 21 is threadedly connected to the nut 23 through the screw rod 22. The side of the nut 23 is connected to the material changing device 3, and the air outlet of the fan 24 is connected to the material changing device 3 through the first pipe 25. The air outlet of the fan 24 is connected to the adaptive cleaning device 4 through the second pipe 26.

[0036] The side surface of one end of the guide tube 31 is connected to the inner wall of the channel 15, and the other end of the guide tube 31 passes through the channel 15 and extends into the outer box 12. A vertical hole 61 is formed in the middle of the upper surface of the guide tube 31 in the outer box 12. A first slide groove 63 is formed on the inner walls on both sides of the guide tube 31. The outer guide rail 34 is installed on the outside of the first slide groove 63. A second slide groove 64 is formed on one side of the outer guide rail 34 and the second slide groove 64 is connected to the first slide groove 63. One end of a slide groove 63 is connected to the rotating plate 32, and the other end of the first slide groove 63 is connected to the inner guide rail 16. The first slide groove 63 and the second slide groove 64 are both slidably connected to the slide cylinder 39. The material loading plate 33 is a V-shaped plate. The end of the material loading plate 33 away from the box body 11 is connected to the socket 35 through the pressure sealing plate 18. A socket 65 is provided at the top of the socket 35, and the bottom end of the plug 36 is plugged into the socket 65. The width of the pressure sealing plate 18 is greater than the width of the sealing groove 62.

[0037] The plug 36 includes: a plug plate 361, which is plugged into the socket 65. The top of the plug plate 361 is connected to the shift rod 363 through the connecting plate 362. The top of the shift rod 363 is connected to the windward plate 364. The center of the top of the windward plate 364 is connected to the top wall of the wind tube 366 through a spring. The windward plate 364 is slidably connected to the inner wall of the wind tube 366. The side of the top of the wind tube 366 is connected to the electromagnetic valve 367. The electromagnetic valve 367 is connected to the fan 24 through the first pipe 25. The windward plate 364 is a bowl-shaped plate. The windward plate 364 opens upward. The top of the wind tube 366 is connected to the side of the nut 23 through the side plate 37.

[0038] During operation, several refilling devices 3 are numbered. Material is placed on the loading plate 33, the number of the refilling device 3 on which the loading plate 33 is located is determined, and the solenoid valve 367 of the refilling device 3 that is unloading the material is activated. For example, if there are three refilling devices 3, numbered 1, 2, and 3, and material is placed on refilling devices 3 No. 1 and No. 2, then only the solenoid valves 367 of No. 1 and No. 2 need to be controlled to enter and exit the housing 11. The air outlet of the fan 24 enters the air duct 366 through the first pipe 25. The partial pressure within the air duct 366 increases, and the windward plate 364 moves downward, carrying the shift rod 363, the connecting plate 362, and the plug 361. The first spring 365 is stretched, and the plug 361 plugs into the socket 35. At this point, the plug 36 is connected to the loading plate 33 as a whole. The first hydraulic cylinder 13 is activated, and the telescopic end of the first hydraulic cylinder 13 moves the sealing plate 14 upward, so that the sealing plate 14 no longer seals the channel 15. The bidirectional motor 41 is activated, the screw rod 22 rotates, and the nut 23 sequentially moves the side plate 37, the air cylinder 366, the windward plate 364, the shift rod 363, the connecting plate 362, the plug plate 361, the socket 35, the material loading plate 33, and the material toward the box body 11. The material loading plate 33 passes through the channel 15 and enters the box body 11. The slide 39 slides along the outer guide rail 34 to the inner guide rail 16, and finally slides to one end of the inner guide rail 16. At this time, the pressure sealing plate 18 is located directly below the sealing groove 62, and the sealing plate 14 immediately moves downward. The bottom end of the sealing plate 14 passes through the top groove 17 and the sealing groove 62 and abuts against the top of the pressure sealing plate 18, thereby sealing the channel 15.

[0039] When adding new materials, testing the different orientations of materials, or removing or replacing materials, there is no need to open the top cover of the box 11 to perform the pick-and-place operation. Instead, the position of the material plate 33 within the box 11 is determined, the channel 15 corresponding to the material plate 33 is opened, and the material plate 33 is quickly removed. Once the channel 15 is opened, the bidirectional motor 41 reverses, and the nut 23 sequentially moves the side panels 37, the air cylinder 366, and the material plate 33 toward the outer box 12. The slide 39 slides along the inner guide rail 16 to the outer guide rail 34, and the material plate 33 moves from the interior of the box 11 into the outer box 12. The sealing plate 14 moves downward and seals the channel 15, reducing the time that the box 11 is connected to the outside world and reducing the humidity loss and temperature changes in the box 11 caused by removing and replacing materials. As the slide 39 slides, one end of the material placing plate 33 continuously extends from one end of the guide tube 31 . When the slide 39 slides along the outer guide rail 34 to the rotating plate 32 , the material placing plate 33 completely extends from one end of the guide tube 31 and is located in the outer box 12 .

[0040] Typically, when salt spraying materials, in order to ensure the stability of the test environment and avoid material state distortion, it is usually not allowed to remove the materials midway. However, different types of materials require different salt spray treatment times, and the materials need to be removed when they reach the time point of the salt spray treatment. This will make it inconvenient for materials with different salt spray treatment times to be salt sprayed at the same time. Materials with different salt spray treatment times can only be processed in batches. When there are many types of materials, the total time of the salt spray treatment will be extended, reducing work efficiency. By constructing the channel 15 and the sealing components and the material changing device 3 that are compatible with it, the treated materials can be replaced in a targeted manner. This allows materials with different salt spray treatment times to be processed in the same batch, and the materials can be removed after the salt spray treatment time reaches the time point, reducing the impact on other materials still undergoing salt spray treatment, and having wide adaptability. It is also possible to quickly remove the materials and seal the channel 15 when it is necessary to perform salt spray treatment on the opposite side of the material. The cross section of the channel 15 is small, and the time the channel 15 is open is short, reducing the impact of the opening of the channel 15.

[0041] Example 2: Figure 1 - Figure 10As shown, the embodiment of the present invention provides a corrosion-resistant detection device based on corrosion foil, and a lower rotating baffle 52 is provided below one end of each material changing device 3, and an adaptive cleaning device 4 is provided on the side of each lower rotating baffle 52 away from the box 11.

The adaptive cleaning device 4 includes: a bidirectional motor 41, the fixed end of the bidirectional motor 41 is connected to the bottom wall of the outer box 12, the rotating end of the bidirectional motor 41 is connected to the support plate 42, and an air box 43 is provided above the support plate 42. The air box 43 passes through the first plate body The air box 43 is connected to the inner wall of the outer box 12, and is connected to several cylinders 45. The inner wall of each cylinder 45 close to the air box 43 is connected to a wind cover 47 through a second spring 46. The wind cover 47 is slidably connected to the inner wall of the cylinder 45, and the wind cover 47 is connected to a movable plate 48 through a push rod 71. The inner side of each movable plate 48 is connected to a dehumidification plate 49. A flat plate 72 is provided above each movable plate 48. The top of the inner side of each flat plate 72 is connected to a guide plate 44. The guide plate 44 is connected to the inner wall of the outer box 12 through the second plate body. The top of the air box 43 is connected to the fan 24 through a second pipe 26.

[0042] The guide plate 44 is an arc plate, and the inner diameter of the guide plate 44 gradually shrinks in the vertical direction. The inner diameter of the top end of the guide plate 44 is larger than the inner diameter of the bottom end of the guide plate 44. The inner diameter of the bottom end of the guide plate 44 is equal to the inner diameter of the flat plate 72. The diameter of the flat plate 72 is larger than the inner diameter of the flat plate 72. The inner side of the dehumidification plate 49 is made of sponge material. The dehumidification plate 49 is used to gather and wrap the material under the action of thrust.

[0043] After the material changing device 3 moves to the box body 11, when the slide 39 moves to the inner guide rail 16 and reaches one end of the outer box 12, the sealing plate 18 is located directly below the sealing groove 62. The bottom end of the sealing plate 14 passes through the top groove 17 and the sealing groove 62 and is pressed against the top of the sealing plate 18, and the channel 15 is sealed. When the material changing device 3 needs to be moved into the outer box 12, the material placing plate 33 moves in the direction of the first slide groove 63. When the slide 39 abuts against the rotating plate 32, one end of the material placing plate 33 is placed on the lower rotating baffle 52. The rotation angle of the material placing plate 33 is adjusted by controlling the height of the lower rotating baffle 52.

[0044] A corrosion resistance detection method for corrosion foil includes a corrosion resistance detection device based on corrosion foil, by opening a channel 15 on the box body 11, so that materials can enter and exit the box body 11 through the channel 15, and the channel 15 can be sealed by the sealing plate 14 to control the connection or isolation between the box body 11 and the outside world, turn on the fan 24, open the electromagnetic valve 367, increase the partial pressure in the air tube 366, and the windward plate 364 moves the plug plate 361 downward and plugs the plug plate 361 into the socket 35. The screw rod 22 rotates, and the nut 23 sequentially moves the side plate 37, the air tube 366, the shift rod 363, the plug plate 361, the socket 35, and the material placement plate 33 toward the direction close to the box body 11. The material placement plate 33 carries the material through the channel 15 and enters the box body 11. The plug plate 361 is separated from the socket 35. The plug plate 361 does not hinder the movement of the sealing plate 14. The sealing plate 14 seals the channel 15. When part or all of the material has completed the salt spray treatment, the corresponding The solenoid valve, the plug plate 361 is plugged into the socket 35, the bidirectional motor 41 reverses, the plug plate 361 drives the material placing plate 33 to move toward the direction close to the outer box 12, and the slide 39 at one end of the material placing plate 33 moves from the inner guide rail 16 to the outer guide rail 34. When the material placing plate 33 is moved out of the box body 11, the sealing plate 14 immediately moves down and seals the channel 15. The slide 39 abuts against the rotating plate 32, and the material placing plate 33 is fully extended from one end of the guide tube 31, thereby completing the replacement or Changing the surface, one end of the material placing plate 33 is placed on the lower rotating baffle 52. As the lower rotating baffle 52 descends, the rod body 38 and the rotating drum rotate relative to each other, one end of the material placing plate 33 moves downward, the material placing plate 33 tilts, and the material slides down into the adaptive cleaning device 4. The wind pressure in the cylinder 45 increases, and the wind cover 47 moves with the moving rod 363, the moving plate 48, and the dehumidifying plate 49 toward the axis of the air box 43. The dehumidifying plate 49 squeezes the material and wraps the material to absorb the liquid on the surface of the material.

[0045] When in use, the material placing plate 33 is completely pulled out from one end of the guide tube 31, and the material placing plate 33 is located in the outer box 12. At this time, the end of the material placing plate 33 away from the box body 11 is placed on the lower rotary baffle 52.

Several dehumidifying plates 49 equidistantly distributed along the circumferential direction are tightened inward, and the dehumidifying plates 49 gradually approach. The dehumidifying plates 49 squeeze the material. The inside of the dehumidifying plates 49 is a soft sponge or a highly elastic water-absorbing part. The dehumidifying plates 49 wrap the material therein, and the dehumidifying plates 49 continue to squeeze. The dehumidifying plates 49 are in contact with each contact surface of the material, and the dehumidifying plates 49 completely absorb the liquid on the surface of the material.

[0047] The material moves in and out of the box 11 along with the material placement plate 33. The two ends of the moving path serve as limit points to facilitate the sealing and rotation of the material placement plate 33. After rotation, the material placement plate 33 adapts to the adaptive cleaning device 4 to complete the material removal and cleaning at one time, which is convenient for material replacement.

[0048] Materials come in a variety of sizes and shapes. Manual wiping is time-consuming and laborious; evaporation through heat is time-consuming and inefficient; and drying after clamping is complex and difficult to maintain. This device utilizes the material's own gravity to drop and flip, allowing liquid in the recessed areas of the material to flow out as much as possible. Then, through elastic plasticity, the dehumidifying plate 49 is pressed against the material. This not only changes the shape of the dehumidifying surface of the dehumidifying plate 49 according to the size and shape of the material, improving its adaptability, but also allows it to contact all sides of the material simultaneously, completing the moisture absorption treatment on all sides at once, which is convenient and quick.
