Description

Technical Field

[0001] The utility model relates to the field of etching on-line automatic liquid replenishing devices, especially the etching on-line automatic liquid replenishing device. Background Art

[0002] The etching on-line automatic liquid replenishing device is a device used for automatically monitoring and adjusting the concentration of the etching solution during etching processing.

[0003] When using an etching tank to perform etching processing on an object, generally, one end of the delivery pipe on the water pump is connected to the inlet of the etching tank. Then, during the etching process, the monitoring probe on the etching tank is used to detect the concentration and volume of the etching solution inside the etching tank in real time. When the etching solution is below the set range value, the water pump is automatically started to pump the chemical solution inside the etching solution barrel into the etching tank through the delivery pipe to supplement fresh chemical solution and make it reach the stable range required for the etching rate. During the process of conveying and adding liquid, if the delivery pipe is accidentally pulled, it may cause one end of the delivery pipe to fall off from the inlet of the etching tank, resulting in leakage of the conveyed etching solution, causing certain damage to other objects and environmental pollution problems. Content of the Utility Model

[0005] The technical solution adopted by the utility model to solve its technical problem is: an etching on-line automatic liquid replenishing device, including a base. One side of the base is fixedly connected with an etching tank. One side of the etching tank is fixedly connected with a monitoring probe. One side of the base is provided with an etching solution barrel. The outlet of the etching solution barrel is fixedly connected with a water pump. The outlet of the water pump is fixedly connected with a delivery pipe. One end of the delivery pipe is inserted into the inlet of the etching tank. One side of the etching tank is provided with a limiting device. The limiting device includes a card hole frame, a gasket, and a screw hole block. A device replacement facilitating structure is arranged between one side of the card hole frame and one side of the etching tank. One side of the card hole frame is fixedly connected with an elastic arc block. One end inner wall of the elastic arc block is rotatably connected with a threaded rod. One end of the threaded rod is inserted into the other end inner wall of the elastic arc block. One end of the threaded rod is inserted into the inner walls of the gasket and the screw hole block.

[0006] The effects achieved by the above components are as follows: By setting the limiting device, after one end of the delivery pipe is inserted into the inlet of the etching tank, the outer surface of one end of the delivery pipe can be stuck in the inner wall of the elastic arc-shaped block. Then, the threaded rod is rotated in the inner wall of the elastic arc-shaped block to a certain position, so that one end of it is stuck in the inner wall of the other end of the elastic arc-shaped block. At this time, the gasket is sleeved on the outer surface of one end of the threaded rod, and one side of it abuts against one side of the elastic arc-shaped block.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] Example 1, as Figures 1-4As shown, the online automatic etching liquid replenishing device includes a base 1. One side of the base 1 is fixedly connected to an etching tank 4. One side of the etching tank 4 is fixedly connected to a monitoring probe 5. One side of the base 1 is provided with an etching liquid bucket 6.

The limiting device 2 includes a hole clamping frame 21, a gasket 26 and a threaded hole block 24. A device replacement facilitating means 3 is provided between one side of the hole clamping frame 21 and one side of the etching tank 4. One side of the hole clamping frame 21 is fixedly connected to an elastic arc-shaped block 22. One end inner wall of the elastic arc-shaped block 22 is rotatably connected to a threaded rod 23. One end of the threaded rod 23 is inserted into the other end inner wall of the elastic arc-shaped block 22. One end of the threaded rod 23 is inserted into the inner walls of the gasket 26 and the threaded hole block 24. After inserting one end of the delivery pipe 8 into the inlet of the etching tank 4, the outer surface of one end of the delivery pipe 8 can be clamped inside the inner wall of the elastic arc-shaped block 22. Then, the threaded rod 23 is rotated to a certain position inside the inner wall of the elastic arc-shaped block 22 so that one end of it is clamped inside the other end inner wall of the elastic arc-shaped block 22. At this time, the gasket 26 is sleeved on the outer surface of one end of the threaded rod 23, with one side abutted against one side of the elastic arc-shaped block 22.

After screwing it to a certain position, one side abuts against the gasket 26, squeezing and tightening one end of the elastic arc-shaped block 22 to clamp and fix the delivery pipe 8, making it fixed and limited at the inlet of the etching tank 4. In this way, when the delivery pipe 8 is accidentally pulled during use, one end will not fall off from the etching tank 4, avoiding the leakage of the etching liquid and damage to other objects. During the etching processing, the monitoring probe 5 on the etching tank 4 will detect the concentration and volume of the etching liquid inside the etching tank 4 in real time. When the etching liquid is below the set range value, the water pump 7 is automatically started to pump the liquid medicine inside the etching liquid bucket 6 into the etching tank 4 through the delivery pipe 8 to supplement fresh liquid medicine, so that it reaches the stable range required for the etching rate.

[0034] Referring to Figure 3 and Figure 4 As shown, in this embodiment, the device 3 for facilitating replacement includes a slot block 31 and a clamping rod 33. One side of the slot block 31 is fixedly connected to one side of the etching tank 4. Through holes 32 are formed on both sides of the inner wall of the slot block 31. One end of the card hole frame 21 is inserted into the inner wall of the slot block 31, and one end of the clamping rod 33 is inserted into the inner walls of the card hole frame 21 and the through hole 32. When it is necessary to replace and maintain the elastic arc block 22, the clamping rod 33 can be manually held and rotated to a certain angle in the inner walls of the through hole 32 and the card hole frame 21, and then aligned with the through hole 32, and then pulled out towards one end. At this time, hold the card hole frame 21 and pull out one end from the inner wall of the slot block 31, so that the elastic arc block 22 can be detached from the etching tank 4, facilitating the replacement and maintenance process.

By providing the magnet blocks 34, after the clamping rod 33 is inserted into the through hole 32 and rotated to a certain angle, it will be adsorbed and fixed by the magnet blocks 34, making it not easy to rotate automatically and avoiding slipping out of the through hole 32. Limiting blocks 35 are symmetrically and fixedly connected to one side of the slot block 31. The limiting blocks 35 are fixedly arranged in an inclined manner on one side of the entrance of the slot block 31.

[0036] Working principle: After one end of the delivery pipe 8 is inserted into the inlet of the etching tank 4, the outer surface of one end of the delivery pipe 8 can be clamped inside the inner wall of the elastic arc-shaped block 22. Then, the threaded rod 23 is rotated inside the inner wall of the elastic arc-shaped block 22 to a certain position so that one end of it is clamped inside the inner wall of the other end of the elastic arc-shaped block 22. At this time, the gasket 26 is sleeved on the outer surface of one end of the threaded rod 23, and one side of it abuts against one side of the elastic arc-shaped block 22. Then, the threaded hole block 24 is screwed onto one end of the threaded rod 23. After it is screwed to a certain position, one side abuts against the gasket 26, squeezing and tightening one end of the elastic arc-shaped block 22 to clamp and fix the delivery pipe 8, so that it is fixed and limited at the inlet of the etching tank 4. In this way, when using, if the delivery pipe 8 is accidentally pulled, one end will not fall off from the etching tank 4, avoiding the leakage of the etching solution and damage to other objects. During the etching process, the monitoring probe 5 on the etching tank 4 will continuously detect the concentration and volume of the etching solution inside the etching tank 4. When the etching solution is below the set range value, the water pump 7 is automatically started to pump the liquid medicine in the etching solution barrel 6 into the etching tank 4 through the delivery pipe 8 to supplement fresh liquid medicine to make it reach the stable range required for the etching rate.

[0037] When it is necessary to replace and maintain the elastic arc-shaped block 22, the clamping rod 33 can be manually held and rotated inside the inner walls of the through hole 32 and the card hole frame 21 to a certain angle so that it aligns with the through hole 32, and then pulled out towards one end. At this time, hold the card hole frame 21 and pull one end of it out from the inner wall of the card slot block 31, so that the elastic arc-shaped block 22 can be disassembled from the etching tank 4, facilitating the replacement and maintenance process.
