[0025] Reference Figure 1-Figure 3The preferred embodiment of the present utility model is a corrosion liquid circulation device for high-pressure corrosion foil perforation, comprising a base 1, on which a gantry 4, a controller 2 and a corrosion tank 3 are provided. The controller 2 and the corrosion tank 3 are respectively located on the inner and outer sides of the gantry 4, a screw rod 6 is provided on the gantry 4, a slide 8 is provided on the screw rod 6 (the screw rod 6 and the slide 8 form a ball screw structure), a connecting rod 9 is provided on the slide 8, and a corrosion liquid tank 10 is provided on the connecting rod 9. A limit rod 7 is provided on the inner side of the gantry 4, and the limit rod 7 is slidably connected to the slide 8. A forward and reverse motor 5 is provided on the outer side of the gantry 4, and the forward and reverse motor 5 is connected to the screw rod 6.

[0026] Specifically, the forward and reverse motors 5 are started, driving the screw rod 6 to rotate. The rotation of the screw rod 6 drives the slide 8 to move horizontally on the screw rod 6, thereby driving the etching liquid tank 10 to move left and right, so that the etching liquid in the etching liquid tank 10 can be evenly discharged in the horizontal direction, making the foil holes in the etching tank 3 more uniform. Among them, the limit rod 7 is slidably connected to the slide 8 to limit the slide 8.

[0027] In this embodiment, a liquid inlet is provided on the corrosion liquid tank 10, and a liquid storage tank 11 and a circulation tank 14 are provided on the outer top of the gantry 4. The liquid storage tank 11 is connected to the circulation tank 14 through a pipe 12, and a solenoid valve 13 is provided on the pipe 12. A pump body group and a liquid concentration meter 15 are provided in the circulation box 14. The output end of one pump body in the pump body group is connected to the liquid inlet through a hose 16, and the input end is connected to the circulation box. The input end of the other pump body is connected to the corrosion tank 3 through a liquid extraction pipe 17, and the output end is connected to the circulation box. Preferably, a filter is provided at the end of the liquid extraction pipe 17 extending into the corrosion tank 3, and the pump body, solenoid valve 13, liquid concentration meter 15 are electrically connected to the controller 2.

[0028] Specifically, after the corrosive liquid in the corrosive liquid tank 10 is discharged into the corrosive tank 3 to corrode and pierce the high-pressure corrosive foil, the pump body in the circulation box 14 is started, and the corrosive liquid after piercing in the corrosive tank 3 is pumped back to the circulation box 14 through the liquid suction pipe 17, and then the concentration of the corrosive liquid in the circulation box 14 is measured by the liquid concentration meter 15. When it is found that the concentration of the corrosive liquid is reduced, the solenoid valve 13 is controlled to open by the controller 2, and the corrosive liquid stored in the liquid storage tank 11 is added to the circulation box 14 to increase the concentration of the corrosive liquid in the circulation box 14, and then the corrosive liquid with increased concentration is discharged into the corrosive liquid tank 10 through the hose 16, thereby realizing the circulation and piercing of the high-pressure corrosive foil by the corrosive liquid, saving energy and improving the piercing efficiency.

[0029] In this embodiment, a placement plate 18 is provided in the corrosion groove 3, and the placement plate 18 is connected to the inner wall of the corrosion groove 3 through a clamping mechanism. The clamping mechanism includes a fixed plate 23 and a lower clamping plate 28 provided on the inner wall of the corrosion groove 3. A sliding rod 26 is provided between the fixed plate 23 and the lower clamping plate 28. The upper clamping plate 25 is slidably connected to the sliding rod 26, and a spring 27 is provided on the sliding rod 26. The spring 27 is located between the upper clamping plate 25 and the lower clamping plate 28.

[0030] Furthermore, the clamping mechanism also includes a screw 24, and a through hole is provided on the fixed plate 23 for use with the screw 24. The screw 24 passes through the fixed plate 23 and is threadedly connected to the upper clamping plate 25. The upper clamping plate 25 and the lower clamping plate 28 are provided with limit blocks for lateral limiting the placement plate 18.

[0031] Furthermore, rubber pads are provided at the positions where the upper clamping plate 25 and the lower clamping plate 25 contact the placement plate 18 .

[0032] Specifically, when installing the placement plate 18, the placement plate 18 is placed on the lower clamping plate 28, and the limit block is supported in the horizontal direction. Then, by rotating the screw 24, the upper clamping plate 25 moves downward on the screw 24 to clamp and fix the placement plate 18. At the same time, the upper clamping plate 25 moves downward while squeezing the spring 27, thereby buffering the pressure exerted by the upper clamping plate 25 on the placement plate 18. When disassembling, the screw 24 is rotated, and the upper clamping plate 25 is reset upward under the dual action of the spring 27 and the rotation of the screw 24, thereby realizing the disassembly of the placement plate 18, which is convenient and quick to install, disassemble or replace the placement plate 18.

[0033] In this embodiment, a heating chamber 19 is provided in the bottom wall of the corrosive liquid tank 10, an electric heating tube 20 is provided in the heating chamber 19, a temperature sensor 21 is provided on the inner wall of the corrosive liquid tank 10, a liquid supply tube 22 is provided on the corrosive liquid tank 10, and the electric heating tube 20 and the temperature sensor 21 are electrically connected to the controller 2.

[0034] Specifically, the etching liquid in the etching liquid tank 10 is heated by the electric heating tube 20 in the heating chamber 19, and the temperature in the etching liquid tank is monitored by the temperature sensor 21. Therefore, the heating degree of the heating tube 20 can be adjusted according to the temperature in the etching liquid tank 10, so as to ensure that the etching liquid in the etching liquid tank 10 enters the etching tank 3 at the most suitable temperature. The etching liquid at the appropriate temperature can accelerate the chemical reaction between the etching liquid and the foil, increase the specific volume of the foil corrosion, and enable the foil to be fully corroded to form holes.

[0035] The utility model circulates the corrosive liquid in the corrosion tank 3 through the pump body in the circulation box 14, and then through the arrangement of the liquid concentration meter 15 and the liquid storage box 11, the concentration of the corrosive liquid circulated in the circulation box 14 will not be reduced. The utility model saves resources while ensuring the pore-forming efficiency of the corrosive liquid in the corrosion liquid tank 10, and is more environmentally friendly.

[0036] The utility model ensures that the corrosive liquid in the corrosive liquid tank 10 enters the corrosion tank 3 at the most suitable temperature by disposing the electric heating tube 20 and the temperature sensor 21 in the heating chamber 19. The corrosive liquid at the suitable temperature can accelerate the chemical reaction between the corrosive liquid and the foil, increase the foil corrosion specific volume, and enable the foil to be fully corroded to form holes.

[0037] Under the premise that no conflict occurs, those skilled in the art may freely combine and superimpose the above-mentioned additional technical features.

[0038] The above description is only a preferred embodiment of the present invention. Any technical solution that achieves the purpose of the present invention by substantially the same means shall fall within the scope of protection of the present invention.
