Description

Technical Field

[0001] This invention relates to the field of corrosion testing equipment technology, and more specifically to a silicone oil release film corrosion resistance testing device. Background Technology

[0002] Silicone oil release films are widely used in electronics, optoelectronics, and medical fields due to their excellent release properties and surface smoothness. In practical applications, silicone oil release films often come into contact with various corrosive chemicals, and their corrosion resistance directly affects the reliability and lifespan of the product. Therefore, corrosion resistance testing of silicone oil release films is a crucial step in quality control.

[0003] Currently, most existing corrosion resistance testing devices employ immersion or dripping methods, applying the corrosive solution directly to the membrane surface and judging the degree of corrosion through manual observation or simple measurement. However, these devices have several shortcomings: First, the amount of corrosive solution applied is difficult to control precisely, especially when dealing with high-viscosity corrosive solutions, which can easily lead to uneven dripping and difficulty in controlling the reaction time; second, there is a lack of real-time monitoring of membrane tension changes during the test, making it impossible to quantitatively reflect the impact of corrosion on the mechanical properties of the membrane; and third, the corrosive solution is prone to splashing during the test, posing safety hazards and cross-contamination risks.

[0004] In addition, existing devices generally lack automated control capabilities, making it difficult to achieve precise delivery of corrosive liquid, accurate control of reaction time, and automatic recording of test data. This results in poor repeatability and low efficiency of test results, failing to meet the demands of modern industrial production for efficient, accurate, and safe testing. Summary of the Invention

The tensioning component 401 includes two sliding portions 4011, which are slidably connected to a second guide rod 304. A clamping portion 4011 is fixedly connected between the sliding portions 4011. 12. The clamping part 4012 has a placement cavity 4013 for placing and clamping the silicone oil release film.

The lower force-bearing part 4072 is fixedly connected to its nail part. The lower force-bearing part 4072 is connected to the lower ring part 4043 via a transmission belt 408.

[0030] In this embodiment, it should be specifically explained that: the two sides of the flat silicone oil release film are placed inside the placement cavity 4013, the second motors 403 on both sides are started, driving the active nail 404 to rotate, thereby driving the first force-bearing nail 406 and the second force-bearing nail 407 to rotate synchronously in the same direction, and the active clamping members 402 on both sides clamp the two sides of the silicone oil release film under the action of the spiral force.

[0031] Reference Figure 2 , Figure 4 and Figure 6 The elastic force-generating component 5 includes a second telescopic rod 501, a second spring 502 sleeved on the outer side of the second telescopic rod 501, and the two ends of the second telescopic rod 501 and the second spring 502 are respectively fixedly connected to the supporting top plate 102 and the splash-proof box 503.

The third guide rod 504 is fixedly connected to the guide hole 508.

[0032] In this embodiment, it should be specifically explained that when the two sliding blocks 205 move to the outwards, they drive the top force inclined plate 206 to move. The movement of the top force inclined plate 206 causes the splash-proof box 503, which is in contact with its inclined surface, to descend under its own weight and the elastic action of the second spring 502 until the fixing protrusion 5036 enters the fixing hole 507, and the splash-proof box 503 protects the reaction range.

[0033] Reference Figure 6 and Figure 8 The splash-proof box 503 includes a splash-proof shell 5031. Force-bearing inclined blocks 5034 are fixedly connected to the four corners of the splash-proof shell 5031. The inclined surfaces of the force-bearing inclined blocks 5034 are in contact with the inclined surfaces of the top-force inclined plate 206 and can slide against each other.

[0034] In this embodiment, it should be specifically noted that the small clearance hole 5032 and the large clearance hole 5033 are provided to avoid obstacles during the descent of the splash guard 503.

[0035] Reference Figure 2 , Figure 3 and Figure 7 The negative pressure generating component 6 includes an active rack 601, the top of which is fixedly connected to the splash shield 503. An active gear 602 is meshed with the inner side of the active rack 601. A fixed shaft 608 is rotatably connected to the center of the active gear 602. A fixed frame 607 is fixedly connected to one side of the fixed shaft 608. The fixed frame 607 is fixedly connected to the support base plate 101. A driven rack 603 is meshed with the other side of the active gear 602. A piston head 604 is fixedly connected to the bottom of the driven rack 603. A piston cylinder 605 is slidably sealed to the outer side of the piston head 604. A vent valve 606 is fixedly sealed to the bottom of the piston cylinder 605.

[0036] In this embodiment, it should be specifically explained that: when the second spring 502 and the splash guard 503 descend, the active rack 601 descends, the active rack 601 drives the active gear 602 to rotate, the active gear 602 drives the driven rack 603 to rise, the driven rack 603 drives the piston head 604 to rise, and a negative pressure is generated inside the piston cylinder 605 and the negative pressure increases.

[0037] Reference Figure 2 , Figure 3 and Figure 7 The material storage and pushing assembly 7 includes a material storage box 701.

The pushing rod 704 is fixedly connected to the splash-proof box 503. The material storage box 701 is fixedly connected to the support base plate 101.

[0038] In this embodiment, it should be specifically explained that when the splash shield 503 descends, it drives the push rod 704 to descend. The push rod 704 gradually approaches the high-viscosity corrosive liquid inside the push cylinder 703 and gradually enters the Y-shaped tube 9 as the push rod 704 descends.

[0039] Reference Figure 2 , Figure 3 and Figure 7 The Y-shaped tube 9 includes a negative pressure tube 901, the top of which is connected to the bottom of the piston cylinder 605. A vent valve 606 is sealed and connected to the connection between the piston cylinder 605 and the negative pressure tube 901. The bottom of the pusher cylinder 703 is fixedly connected to a liquid outlet tube 902, the top of which is connected to the bottom of the pusher cylinder 703. A switch valve 705 is sealed and connected to the connection between the pusher cylinder 703 and the liquid outlet tube 902. The bottom of the vertical tube 903 is fixedly connected to a liquid outlet tube 902. The negative pressure tube 901, the liquid outlet tube 902, and the vertical tube 903 are interconnected.

[0040] In this embodiment, it should be specifically explained that by controlling the opening and closing time and opening degree of the vent valve 606, the magnitude and duration of the negative pressure generated in the section from the negative pressure pipe 901 to the vertical pipe 903 can be adjusted. In this way, the distance of the rising and falling of the etchant inside the vertical pipe 903 can be controlled, and the amount and time of the reaction between the silicone oil release film and the etchant can be precisely controlled.

[0041] Working principle of the invention: The main problem solved in this embodiment is that the tension change of the silicone oil release film after corrosion is numerically reflected by the initiative of the first motor 201 and the accuracy of the laser reflection of the laser receiving and transmitting component 8. The problem of high viscosity corrosive liquid being difficult to accurately and quantitatively transport and control in real time is solved by utilizing the initiative of the negative pressure generating component 6 and the material storage and pushing component 7 and the internal permeability of the Y-shaped tube 9.

[0042] The specific steps are as follows: First, place both sides of the flat silicone release film into the placement cavity 4013. Start the second motors 403 on both sides, driving the active pins 404 to rotate, thereby causing the first force-bearing pins 406 and the second force-bearing pins 407 to rotate synchronously in the same direction. The active clamping members 402 on both sides clamp the sides of the silicone release film under the action of the spiral force. Start the first motors 201 on both sides, driving the first screw 202 to rotate. The first screw 202 moves the sliding block 205 away from the silicone release film. The sliding block 205 pulls the fixing assembly 4 through the first spring 302. Component 4 also stretches the silicone release film. When the laser receiving and emitting component 8 senses that the first springs 302 on both sides simultaneously reach the same specified elongation threshold, it indicates that the deformation of the silicone release film meets the test standard. When the two sliding blocks 205 move outwards, they drive the top force inclined plate 206 to move. The movement of the top force inclined plate 206 causes the splashproof box 503, which is in contact with its inclined surface, to descend under its own weight and the elastic action of the second spring 502 until the fixing protrusion 5036 enters the fixing hole 507. The splashproof box 503 protects the reaction area and prevents corrosion during the test. When the liquid splashes, the force-bearing inclined block 5034 completely separates from the top force inclined plate 206. As the second spring 502 and the splash shield 503 descend, the driving rack 601 descends, driving the driving gear 602 to rotate. The driving gear 602 drives the driven rack 603 to rise, which in turn drives the piston head 604 to rise. A negative pressure is generated inside the piston cylinder 605, and this negative pressure increases. At this time, the vent valve 606 is not open, and no air pressure is generated inside the negative pressure pipe 901. When the splash shield 503 descends, it drives the push rod 704 to descend, and the push rod 704 gradually approaches... The high-viscosity etchant inside the pusher cylinder 703 gradually enters the bottom of the vertical pipe 903 from the top of the outlet pipe 902 as the pusher rod 704 descends. Due to the high viscosity of the etchant, it does not fall onto the silicone oil release film, but it comes into contact with and reacts with it. At this time, by controlling the opening and closing time and opening degree of the vent valve 606, the magnitude and duration of the negative pressure generated in the section from the negative pressure pipe 901 to the vertical pipe 903 can be adjusted. This controls the distance of the etchant rising and falling inside the vertical pipe 903, and thus the amount and time of the reaction between the silicone oil release film and the etchant can be precisely controlled. When the etchant comes into contact with the silicone release film and reacts for a specific time threshold, the tension inside the silicone release film decreases due to corrosion. At this time, the vent valve 606 is opened to generate negative pressure, which draws up the etchant and terminates the reaction. As the tension inside the silicone release film decreases, the fixing components 4 on both sides and the first telescopic rod 301 will move away from each other due to the reduced tension. The first telescopic rod 301 contracts. At this time, the rotation of the first motor 201 drives the sliding block 205 and the laser receiving and emitting component 8 to move, causing the first telescopic rod 301 to deform again to the elongation threshold at which it begins to stretch. At this time, the distance between the sliding block 205 and the tensioning component 401 is measured by the laser receiving and emitting component 8. The changing value can well reflect the corrosion rate of the silicone release film. When it is necessary to continue measuring, the vent valve 606 is closed, and the etchant comes into contact with the silicone release film again to corrode it, and the measurement continues. After the measurement is completed, the first motor 201 is started. The first motor 201 drives the top force inclined plate 206 to gradually contact the force-bearing inclined block 5034. Through the component force of mutual compression, the splash-proof box 503 rises. The rise of the splash-proof box 503 causes the piston head 604 to fall until the negative pressure inside the piston head 604 disappears. Then, the air inside the piston head 604 pushes the corrosive liquid suspended on the vertical pipe 903 to be discharged into the waste liquid collection tank. The rise of the splash-proof box 503 causes the negative pressure vacuum valve 702 inside the push rod 704 to open. The corrosive liquid inside the storage box 701 enters the push cylinder 703 to prepare for the next test.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
