Description

Technical Field

[0001] The utility model relates to the technical field of wet chemical etching devices, and particularly relates to a metal wet chemical etching device. Background Technique

[0002] The chemical reaction of wet etching belongs to the reaction between a liquid phase and a solid phase. When wet etching is in operation, first, the reactants in the solution use the diffusion effect to pass through a very thin boundary layer to reach the surface of the etched film. Then, these reactants chemically react with the molecules on the film surface and generate various products. These products located on the film surface also use the diffusion effect to pass through the boundary layer into the solution, and then are discharged with the solution. The erosion of metal by air at high temperature is usually called oxidation, and the oxidation products of metal wet etching are called "scale". Corrosion and scaling can prevent the base material from being wetted by the adhesive. It is necessary to remove the adhesive to expose a new surface of the base material. The surface usually requires appropriate roughness to increase the bonding area and improve the bonding strength. For metal materials, wet etching is usually carried out while removing rust to clean impurities such as oxides and carbonates on the metal surface.

[0003] Existing metal wet chemical etching devices make the metal block contact with the etching solution by stirring or shaking up and down. The flipping amplitude is small, and the efficiency of impurity shedding on the metal surface is low. Moreover, after processing, the metal blocks cannot be quickly fished out, and it is very troublesome to fish them out one by one. After the existing metal wet chemical etching devices are processed, they cannot perform further cleaning steps on the metal blocks, and it is necessary to transfer the metal blocks into a cleaning device, which is very inconvenient. Therefore, a metal wet chemical etching device is proposed for the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a metal wet chemical etching device to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] A metal wet chemical etching device includes a housing and a screen. One side of the housing is provided with a fixed pipe, the inside of the fixed pipe is provided with a limiting hole, a fixed rod is slidably connected inside the limiting hole, one end of the fixed rod is fixedly connected with a limiting rod, the end of the fixed rod far from the limiting rod is fixedly connected with a fixing plate, one side of the fixing plate is fixedly connected with a magnet layer located outside the fixed rod, one end of the screen is provided with a first limiting groove, the top of the screen is provided with a second limiting groove, the top of the screen is fixedly connected with a pull rod, the end of the housing far from the fixed pipe is fixedly connected with a motor, and the output end of the motor penetrates the housing and is fixedly connected with a limiting block, and a third limiting groove is provided at the end of the limiting block far from the motor.

[0007] Preferably, a drain port is provided at the bottom end of the outer shell, a sealing cover is provided at the top end of the outer shell, and a sealing block located inside the outer shell is fixedly connected to the bottom end of the sealing cover.

[0008] Preferably, the sealing block is rectangular in shape, and the size of the sealing block is the same as the internal size of the outer shell.

[0009] Preferably, the first limiting groove, the limiting rod, and the third limiting groove are rectangular in shape, and limiting rods are slidably connected inside the first limiting groove and the third limiting groove.

[0010] Preferably, the pull rod is T-shaped, and the number of pull rods is two, which are symmetrically arranged on the surface of the screen.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. In the present utility model, through components such as the outer shell, fixed tube, limiting hole, fixed rod, limiting rod, first limiting groove, screen, second limiting groove, motor, limiting block, and third limiting groove, under the action of the fixed tube, limiting hole, limiting block, and third limiting groove, the fixed rod and the screen are fixed and supported. The motor drives the limiting block to rotate, and the limiting block drives the limiting rod and the fixed rod to rotate in the limiting hole through the third limiting groove. The limiting rod drives the screen to rotate under the action of the first limiting groove. The screen drives the iron blocks inside to swing rapidly and substantially, enabling the iron blocks to contact the etching solution in all directions. While the screen swings the iron blocks, the iron blocks will collide with the screen, making the surface impurities fall off more quickly, thus solving the problem that in the existing metal wet chemical etching device, the metal blocks are made to contact the etching solution by stirring or shaking up and down, with a small flipping amplitude and low efficiency of impurity removal from the metal surface.

[0013] 2. In the present utility model, through components such as the limiting block, third limiting groove, screen, first limiting groove, pull rod, fixed rod, limiting hole, limiting rod, magnet layer, and fixing plate, the fixing plate drives the magnet layer, fixed rod, and limiting rod to move, and the limiting rod is pulled out from the first limiting groove of the screen. Then, the screen and the iron blocks can be lifted out all at once through the pull rod, thus solving the problem that after processing, it is impossible to quickly lift the metal blocks out, and it is very troublesome to fish them out one by one.

[0014] 3. In the utility model, by providing the screen, drain outlet, shell, motor, limit block, third limit groove, fixed pipe, limit hole, first limit groove and other components, when the iron block needs to be cleaned, the drain outlet is opened through the external valve, and the corrosive liquid is drained through the drain outlet. After draining, the valve is closed, and clean water is added from the top of the shell. Then, the iron block is driven to continue to be swung significantly through the screen in accordance with the above stirring steps, so that the iron block and the clean water are in complete contact, so as to achieve the effect of cleaning the iron block. After cleaning is completed, the clean water can be discharged by opening the external valve. There is no need to transfer the iron block, and impurity removal and cleaning can be completed in one device, thereby solving the problem that the existing metal wet chemical corrosion device cannot perform further cleaning steps on the metal block after processing is completed, and the metal block needs to be transferred to the cleaning device, which is very inconvenient.

[0025] Please refer to Figure 1-6 , the present utility model provides a technical solution:

[0026] A metal wet chemical etching device includes a housing 1 and a screen 9. One side of the housing 1 is provided with a fixed tube 2, and a limiting hole 3 is provided inside the fixed tube 2. A fixed rod 4 is slidably connected inside the limiting hole 3. One end of the fixed rod 4 is fixedly connected to a limiting rod 5, and the end of the fixed rod 4 away from the limiting rod 5 is fixedly connected to a fixing plate 7. A magnet layer 6 is fixedly connected to one side of the fixing plate 7 and located outside the fixed rod 4. One end of the screen 9 is provided with a first limiting groove 8, the top of the screen 9 is provided with a second limiting groove 10, and a pull rod 11 is fixedly connected to the top of the screen 9. One end of the housing 1 away from the fixed tube 2 is fixedly connected to a motor 12, and the output end of the motor 12 penetrates through the housing 1 and is fixedly connected to a limiting block 13. A third limiting groove 14 is provided at the end of the limiting block 13 away from the motor 12.

[0027] A drain port 15 is provided at the bottom end of the housing 1, and a sealing cover 17 is provided at the top end of the housing 1. A sealing block 16 is fixedly connected to the bottom end of the sealing cover 17 and located inside the housing 1. The shape of the sealing block 16 is rectangular, and the size of the sealing block 16 is the same as the internal size of the housing 1. The shapes of the first limiting groove 8, the limiting rod 5, and the third limiting groove 14 are rectangular, and the limiting rod 5 is slidably connected inside both the first limiting groove 8 and the third limiting groove 14. The shape of the pull rod 11 is T-shaped, and the number of pull rods 11 is two, symmetrically arranged on the surface of the screen 9.

[0028] Workflow: When the metal wet chemical etching device is needed, the whole device is externally powered. First, the sealing cover 17 and the sealing block 16 are pulled out upwards. Then, the iron block is placed into the screen 9 through the second limiting groove 10, and the etching solution is poured through the opening above the outer shell 1. At this time, the valve outside the drain port 15 is in the closed state. Then, the sealing cover 17 and the sealing block 16 are covered again. Under the action of the fixed tube 2, the limiting hole 3, the limiting block 13 and the third limiting groove 14, the fixed rod 4 and the screen 9 are fixed and supported. The motor 12 drives the limiting block 13 to rotate. The limiting block 13 drives the limiting rod 4 and the fixed rod 5 to rotate in the limiting hole 3 through the third limiting groove 14. The limiting rod 5 drives the screen 9 to rotate under the action of the first limiting groove 8. The screen 9 drives the iron block inside to swing rapidly and significantly, making the iron block contact the etching solution in all directions. While the screen 9 swings the iron block, the iron block will impact the screen 9, making the surface impurities fall off more quickly. After the impurity removal is completed, the drain port 15 is opened through an external valve, and the etching solution is emptied through the drain port 15. After emptying, the valve is closed, the sealing cover 17 and the sealing block 16 are opened, and clean water is added from above the outer shell 1. Next, it is the same as the above stirring step. The screen 9 drives the iron block to swing significantly again, making the iron block and the clean water fully contact to achieve the effect of cleaning the iron block. After the cleaning is completed, the external valve is opened to drain the clean water. There is no need to transfer the iron block, and impurity removal and cleaning can be completed in one device. After the cleaning is over, the sealing cover 17 and the sealing block 16 are opened again. When the iron block needs to be taken out, the fixing plate 7 drives the magnet layer 6, the fixed rod 4 and the limiting rod 5 to move, and the limiting rod 5 is pulled out from the first limiting groove 8 of the screen 9. Then, the screen 9 and the iron block can be lifted out all at once through the pull rod 11. The magnet layer 6 can make the fixing plate 7 and the fixed tube 2 adsorb together to prevent the limiting rod 5 from accidentally falling off from the third limiting groove 14 when rotating.
