The patent drives two connecting seats to move in two through grooves through two electric push rods, and the two connecting seats drive two moving blocks to move in the strip groove, and at the same time drive the bottom corrosion tube to move, and stop when moving to the impurity. The corrosion liquid in the corrosion tube corrodes the surface of the bottom corrosion foil, and the two connecting seats are used to drive the two limit blocks to move in the through groove. The two limit blocks cooperate with the two connecting blocks to drive the two moving seats to move in the moving groove, thereby driving the two conductive rods to move. When moving to the appropriate position, the two electric telescopic rods on the two mounting shells cooperate with the two connecting pieces to drive the two conductive rods to move, and the corrosion foil surface is expanded.

[0004] In the above patent, two limit blocks are driven to move in the through slot by two connecting seats, and the two limit blocks cooperate with the two connecting blocks to drive the two moving seats to move in the moving slot, thereby driving the two conductive rods to move.

However, it is difficult to position and correct the position of the foil before the expansion operation. Inaccurate positioning will cause the actual position of the hole to deviate from the design requirements, thereby increasing material waste and cost. Summary of the invention

[0014] A hole enlarging method of a corrosion foil corrosion enlarging device, using the above-mentioned corrosion foil corrosion enlarging device, comprises the following steps:

[0015] Step 1: manually pull the adjustment rod upward, and after the adjustment frame moves upward, pass the foil to be corroded between the rotating rod and the pressing roller, and then fix the foil to be corroded with the traction device after passing between the rotating rod and the pressing roller;

[0016] Step 2: After the foil to be corroded is fixed to the traction device, the traction device operates to traction the foil to be corroded, the servo motor operates to drive the pressing roller to rotate clockwise, the pressing roller rotates clockwise to drive the squeezing rod to rotate, the squeezing rod rotates to contact the positioning block and squeeze the positioning block;

[0017] Step 3: The positioning block is squeezed by the squeezing rod and moves toward the direction close to the foil. The movement of the positioning block toward the direction close to the foil drives the positioning rod and the positioning frame to move. The positioning frame moves to contact the foil to be corroded and performs positioning correction on it.

[0018] Step 4: After the extrusion rod continues to rotate and disengages from the positioning block, the positioning block disengages from the extrusion rod, so that the positioning rod moves away from the foil under the elastic action of the second spring, and the movement of the positioning rod away from the foil drives the positioning block and the positioning frame to move and reset;

[0019] Step 5: When the foil to be corroded moves to the bottom of the corrosion frame, the displacement device drives the liquid spraying device to move horizontally, and the liquid spraying device moves horizontally to evenly spray the foil to be corroded. At the same time, the electric push rod drives the corrosion rod to move downward to expand the hole of the foil to be corroded.

[0020] The present invention provides a foil corrosion expansion device, which has the following beneficial effects:

[0021] (1) The invention drives the adjusting frame downward by moving the adjusting rod downward to reset, and the adjusting frame moves downward to drive the rotating rod downward to reset and contact the foil to be corroded. By being able to process foils of different thicknesses, the adaptability of the equipment is enhanced, and it can meet a variety of production needs. It also prevents sliding or displacement during the hole expansion process, and reduces the risk of damage to the foil during hole expansion. The positioning block moves toward the foil to drive the positioning rod and the positioning frame to move, and the positioning frame moves to contact the foil to be corroded and position it. Through pre-positioning and correction, it can be ensured that the actual position of the hole is consistent with the design requirements, avoiding hole position problems caused by position deviation.

[0022] (2) The invention moves the load-bearing plate to move and reset, thereby driving the load-bearing rod and the scraper rod to move and reset. The scraper rod reciprocates to scrape the top of the foil. The reciprocating motion of the scraper rod can effectively remove oil and other pollutants on the foil surface, improve the uniform infiltration of the corrosive agent during the corrosion process, and thus improve the effect of corrosion expansion. The scraper rod moves upward due to the reaction force of squeezing the thicker foil. The scraper rod moves upward while always maintaining contact with the foil. Excessive scraping will cause excessive corrosive agent to act on some areas of the foil surface, while insufficient corrosive agent will act on other areas, resulting in uneven corrosion. By preventing the scraper rod from excessively scraping, it is possible to ensure that the corrosive agent is evenly distributed, thereby achieving a more uniform hole expansion effect.

[0023] (3) In the present invention, the mineral oil entering the spray pipe squeezes the rubber block, and the rubber block is deformed by the squeezing of the mineral oil entering the spray pipe. The deformation of the rubber block releases the seal of the spray pipe. After the seal of the spray pipe is released, part of the mineral oil in the quantitative frame is sprayed through the spray pipe to the rotating part between the pressing roller and the placement frame. Good lubrication can make the movement between the pressing roller and the placement frame smoother, which helps to maintain a stable pressure during the hole expansion process, thereby ensuring the stability of the corrosion hole expansion process. In addition, quantitative spraying can ensure that the amount of mineral oil sprayed each time is accurate, thereby avoiding excessive or insufficient lubrication. BRIEF DESCRIPTION OF THE DRAWINGS

Through pre-positioning and correction, it can be ensured that the actual position of the hole is consistent with the design requirements, and hole position problems caused by position deviation can be avoided.

[0034] A No. 1 spring is arranged between the adjusting rod 12 and the placing frame 2 , and the No. 1 spring can drive the adjusting rod 12 to reset. The top of the positioning block 19 is arranged as an inclined surface, and a linkage plate 21 is fixedly installed on the positioning block 19 .

[0035] A No. 2 spring is arranged between the positioning rod 18 and the placement frame 2, and the No. 2 spring can drive the positioning rod 18 to reset. The end of the squeezing rod 17 away from the pressing roller 16 is arranged as an arc surface.

[0036] A hole enlarging method of a corrosion foil corrosion enlarging device, using the above-mentioned corrosion foil corrosion enlarging device, comprises the following steps:

[0037] Step 1: manually pull the adjusting rod 12 upward, and after the adjusting frame 13 moves upward, the foil to be corroded passes between the rotating rod 14 and the pressing roller 16, and the foil to be corroded passes between the rotating rod 14 and the pressing roller 16 and is fixed to the traction device 4;

[0038] Step 2: After the foil to be corroded is fixed to the traction device 4, the traction device 4 operates to traction the foil to be corroded, the servo motor 15 operates to drive the pressing roller 16 to rotate clockwise, the pressing roller 16 rotates clockwise to drive the squeezing rod 17 to rotate, the squeezing rod 17 rotates to contact the positioning block 19 and squeeze the positioning block 19;

[0039] Step 3: The positioning block 19 is squeezed by the squeezing rod 17 and moves toward the foil. The positioning block 19 moves toward the foil and drives the positioning rod 18 and the positioning frame 20 to move. The positioning frame 20 moves to contact the foil to be etched and positions and corrects it.

[0040] Step 4: After the extrusion rod 17 continues to rotate and disengages from the positioning block 19, the positioning block 19 disengages from the extrusion rod 17, so that the positioning rod 18 moves away from the foil under the elastic action of the second spring, and the positioning rod 18 moves away from the foil, driving the positioning block 19 and the positioning frame 20 to move and reset;

[0041] Step 5: When the foil to be corroded moves to the bottom of the corrosion frame 6, the displacement device 9 drives the liquid spraying device 11 to move horizontally, and the liquid spraying device 11 moves horizontally to evenly spray the foil to be corroded. At the same time, the electric push rod 10 drives the corrosion rod to move downward to expand the hole of the foil to be corroded.

[0042] When the present embodiment is working, the adjusting rod 12 is manually pulled to move upward, and the adjusting rod 12 moves upward to squeeze the No. 1 spring. The No. 1 spring is squeezed by the adjusting rod 12 to produce deformation and store force. At the same time, the adjusting rod 12 moves upward to drive the adjusting frame 13 to move upward. After the adjusting frame 13 moves upward, the foil to be corroded passes between the rotating rod 14 and the pressing roller 16. After the foil to be corroded passes between the rotating rod 14 and the pressing roller 16, it is fixed to the traction device 4. After the foil to be corroded is fixed to the traction device 4, the traction device 4 operates to pull the foil to be corroded. At the same time, the adjusting rod 12 is released so that the adjusting rod 12 moves downward and resets under the elastic force of the No. 1 spring. The adjusting rod 12 moves downward and resets to drive the adjusting frame 13 to move downward. The adjusting frame 13 moves downward and drives the rotating rod 14 to move downward and reset and contact the foil to be corroded. At the same time, the servo motor 15 operates to drive the pressing roller 16 to rotate clockwise. The pressing roller 16 rotates clockwise to drive the extrusion rod 17 to rotate. The extrusion rod 17 rotates to contact the positioning block 19 and aligns the positioning block 19. The block 19 is squeezed, and the positioning block 19 is squeezed by the squeezing rod 17 and moves in the direction close to the foil. The positioning block 19 moves in the direction close to the foil and drives the positioning rod 18 and the positioning frame 20 to move. The positioning frame 20 moves to contact the foil to be corroded and positions and corrects it. At the same time, the positioning rod 18 moves in the direction close to the foil to squeeze the No. 2 spring. The No. 2 spring is deformed and accumulates force under the pressure of the positioning rod 18. After the squeezing rod 17 continues to rotate and disengages from the contact with the positioning block 19, the positioning block 19 is disengaged from the contact with the squeezing rod 17, so that the positioning rod 18 moves in the direction away from the foil under the elastic action of the No. 2 spring. The positioning rod 18 moves in the direction away from the foil and drives the positioning block 19 and the positioning frame 20 to move and reset. When the foil to be corroded moves to the bottom of the corrosion frame 6, the displacement device 9 drives the liquid spraying device 11 to move horizontally. The liquid spraying device 11 moves horizontally to evenly spray the foil to be corroded. At the same time, the electric push rod 10 drives the corrosion rod to move downward to expand the hole of the foil to be corroded.

[0043] See also Figure 1-Figure 7On the basis of the above embodiment, in another embodiment of the present invention, a pretreatment device for cleaning the foil is arranged on the surface of the placement frame 2, and a maintenance device is arranged on the top of the placement frame 2. The pretreatment device includes an L-shaped plate 221, a load-bearing plate 222, a load-bearing rod 223, a reset spring 224, a scraper rod 225 and a limit plate 226. The L-shaped plate 221 is fixedly mounted on one side of the placement frame 2 close to the etching table 5, the load-bearing plate 222 slides through the left and right walls of the L-shaped plate 221, the load-bearing rod 223 slides through the upper and lower walls of the load-bearing plate 222, the reset spring 224 is arranged between the load-bearing plate 222 and the load-bearing rod 223, the scraper rod 225 is fixedly mounted on the bottom of the load-bearing rod 223, and the limit plate 226 is fixedly mounted on the top of the load-bearing rod 223. The reciprocating motion of the scraper rod 225 can effectively remove oil and other pollutants on the surface of the foil, improve the uniform infiltration of the corrosive agent during the etching process, and ensure that the corrosive agent is evenly distributed by preventing the scraper rod 225 from excessively scraping, thereby achieving a more uniform hole expansion effect.

[0044] An inclined panel 227 is fixedly installed at the bottom of the load-bearing plate 222, and one end of the load-bearing plate 222 close to the linkage plate 21 is set as an inclined surface, the linkage plate 21 is in contact with the linkage plate 21, and a No. 3 spring is set between the L-shaped plate 221 and the load-bearing plate 222, one end of the No. 3 spring is set on the surface of the L-shaped plate 221, and the other end is set on the top of the load-bearing plate 222, and the No. 3 spring can drive the load-bearing plate 222 to reset.

[0045] The maintenance device includes a liquid storage frame 231, a quantitative frame 232, a quantitative plate 233, a quantitative rod 234, a quantitative hole 235 and a liquid spray pipe 236. The liquid storage frame 231 is fixedly installed on the top of the U-shaped plate 3, the quantitative frame 232 is fixedly installed on the bottom of the inner wall of the liquid storage frame 231, the quantitative plate 233 is slidably installed on the inner wall of the quantitative frame 232, the quantitative rod 234 is fixedly installed on one side of the quantitative plate 233 close to the inclined plate 227, the quantitative hole 235 is opened on the surface of the quantitative frame 232, and the liquid spray pipe 236 is fixedly installed at the bottom of the quantitative frame 232. Good lubrication can make the movement between the pressing roller 16 and the placing frame 2 smoother, which helps to maintain a stable pressure during the hole expansion process, thereby ensuring the stability of the corrosion hole expansion process, and quantitative spraying can ensure that the amount of mineral oil sprayed each time is accurate, thereby avoiding excessive or insufficient lubrication.

[0046] A protection spring 237 is provided between the quantitative rod 234 and the liquid storage frame 231 , and the quantitative rod 234 can be driven to reset by the protection spring 237 . A rubber block is provided inside the liquid spraying pipe 236 , and the quantitative rod 234 is in contact with the inclined plate 227 .

[0048] When the present embodiment is working, the positioning block 19 moves toward the direction close to the foil, driving the linkage plate 21 to move and contact the load-bearing plate 222 and squeeze the load-bearing plate 222. The load-bearing plate 222 is squeezed by the linkage plate 21 and moves in the direction away from the pressing roller 16. The load-bearing plate 222 moves in the direction away from the pressing roller 16 to squeeze the No. 3 spring. The No. 3 spring is squeezed by the load-bearing plate 222 to produce deformation and accumulate force. At the same time, the load-bearing plate 222 moves in the direction away from the pressing roller 16, driving the load-bearing rod 223 to move. The movement of the load-bearing rod 223 drives the scraper rod 225 to move. When the positioning block 19 moves in the direction away from the foil and drives the linkage plate 21 to move, the linkage plate 21 moves and separates from the load-bearing plate 22. 2 makes the load-bearing plate 222 move and reset in the direction close to the pressing roller 16 under the elastic force of the No. 3 spring. The movement and reset of the load-bearing plate 222 drives the load-bearing rod 223 and the scraper rod 225 to move and reset. The scraper rod 225 reciprocates to scrape the top of the foil. If a thicker foil is encountered, the scraper rod 225 will squeeze the thicker foil when in contact with the thicker foil. At the same time, the scraper rod 225 moves upward under the reaction force of squeezing the thicker foil. The scraper rod 225 moves upward and drives the load-bearing rod 223 to move and pull the reset spring 224. The reset spring 224 is deformed and stored force by the pulling of the load-bearing rod 223. The scraper rod 225 moves upward while always keeping in contact with the foil.

[0049] The load-bearing plate 222 moves in a direction away from the pressing roller 16, driving the inclined plate 227 to move. The inclined plate 227 moves to contact the quantitative rod 234 and squeezes the quantitative rod 234. The quantitative rod 234 is squeezed by the inclined plate 227 and moves in a direction away from the L-shaped plate 221. The quantitative rod 234 moves in a direction away from the L-shaped plate 221 to squeeze the protection spring 237. The protection spring 237 is squeezed by the quantitative rod 234 to deform and accumulate force. At the same time, the quantitative rod 234 moves in a direction away from the L-shaped plate 221, driving the quantitative plate 233 to move. The quantitative plate 233 moves out of contact with the quantitative hole 235 and squeezes the quantitative frame Part of the space inside 232 is sealed with mineral oil, and the metering plate 233 continues to move to squeeze part of the mineral oil inside the metering frame 232. Part of the mineral oil inside the metering frame 232 is squeezed by the metering plate 233 and enters the spray pipe 236. The mineral oil entering the spray pipe 236 squeezes the rubber block, and the rubber block is squeezed by the mineral oil entering the spray pipe 236 and deformed. The deformation of the rubber block releases the seal of the spray pipe 236. After the seal of the spray pipe 236 is released, part of the mineral oil inside the metering frame 232 is sprayed to the rotating part between the pressing roller 16 and the placement frame 2 through the spray pipe 236.
