Description

Technical Field

[0001] The present invention belongs to the technical field of semiconductor manufacturing, and specifically relates to an electrolytic polishing device for semiconductor stainless steel pipes. Background Art

[0002] In the field of semiconductor manufacturing, stainless steel pipes, as an important material, are widely used in the conveying systems of high-purity gases and liquids. In order to meet the extremely high requirements of semiconductor manufacturing for the surface finish, cleanliness, and corrosion resistance of materials, stainless steel pipes usually need to be subjected to electrolytic polishing treatment. Electrolytic polishing removes the microscopic unevenness, contaminants, and oxide layers on the surface of stainless steel pipes through electrochemical dissolution, thereby obtaining a smooth, clean, and corrosion-resistant surface.

[0003] For example, the utility model with the publication number CN114808100A discloses an electrolytic polishing device and method for the inner pipe of a stainless steel pipe. The stainless steel pipe to be polished is placed on a steel pipe placement rack, and the front end of the stainless steel pipe to be polished is connected to a steel pipe connection port. The anode electrode part is fixed on the stainless steel pipe to be polished, and the front end of the conductive rod is inserted into the front end of the cavity of the stainless steel pipe to be polished. First, start the electrolyte water pump, and the electrolyte flows into the cavity of the stainless steel pipe to be polished from the connector until it flows out from the rear end of the stainless steel pipe to be polished. At this time, start the electric box. After the circuit is connected, start the driving device. The driving device drives the traction frame to pull the conductive rod out of the cavity of the stainless steel pipe to be polished at a certain speed. During the movement, the inner wall of the stainless steel pipe to be polished is electrolytically polished. It has the advantages of simple structure, low manufacturing cost, high automation degree, and good electrolytic polishing effect.

[0004] However, in the existing electrolytic polishing device for semiconductor stainless steel pipes during the electrolytic polishing process, the stainless steel pipe needs to be fixed as the anode in the polishing tank and form a stable electric field distribution with the cathode. However, the fixing method of the stainless steel pipe in the traditional device is often relatively simple, usually hanging and fixing it on the top of the polishing tank, making it difficult to fix stainless steel pipes with different diameters and lengths as required. At the same time, it may leave indentations or scratches on the surface of the stainless steel pipe, affecting the surface quality after polishing. Moreover, during the electrolytic polishing process, water molecules in the electrolyte will be electrolyzed under the action of current, generating hydrogen and oxygen. These gases adhere to the surface of the stainless steel pipe in the form of bubbles, hindering the contact between the electrolyte and the metal surface, resulting in local poor polishing, forming defects, reducing the effective polishing area, and causing a decline in polishing efficiency.

[0005] Therefore, an electrolytic polishing device for semiconductor stainless steel pipes is proposed to solve the problems raised in the background art. Summary of the Invention

[0006] To solve the problems raised in the above background art, the present invention provides an electrolytic polishing device for semiconductor stainless steel pipes.

[0007] To achieve the above object, the present invention provides the following technical solutions: An electrolytic polishing device for a semiconductor stainless steel pipe, comprising an electrolytic tank, a control box fixedly arranged on the outer wall of the electrolytic tank, and a plurality of moving blocks fixedly arranged at the bottom of the electrolytic tank. It further includes:

[0008] A stainless steel pipe body, which is located inside the electrolytic tank and is polished by the electrolyte in the electrolytic tank;

[0009] A fixing mechanism, which is located inside the electrolytic tank and is arranged in a linear array in multiple groups for fixing a plurality of stainless steel pipe bodies;

[0010] An antifoaming mechanism, which is in the same plane as the fixing mechanism and is used to eliminate the bubbles on the stainless steel pipe body;

[0011] Among them, the fixing mechanism includes a mounting plate, two clamping blocks symmetrically arranged on both sides of the top of the mounting plate, clamping claws fixedly arranged at the bottoms of the two clamping blocks, and a driving component arranged at the center of the two clamping blocks for driving the two clamping claws to approach or move away from each other.

[0012] Preferably, the two clamping blocks are arc-shaped, and rubber gaskets are fixedly connected to the sides of the two clamping blocks that are close to each other, and the rubber gaskets are in contact with the stainless steel pipe body.

[0013] Preferably, the two clamping claws are Z-shaped and are hinged to the mounting plate at the center.

[0014] Preferably, the driving component includes a support plate, a driving block fixedly arranged at the bottom of the support plate, a support spring fixedly installed at the center of the bottom of the driving block, and two floating springs arranged at the bottoms of the two clamping claws.

[0015] Preferably, a sliding groove is formed on the mounting plate, the support plate slides along the sliding groove, and a connecting seat is fixedly arranged on the surface of the mounting plate.

[0016] Preferably, insertion grooves are formed on both sides of the top of the connecting seat symmetrically, and the floating springs are snap-fitted and fixed with the insertion grooves.

[0017] Preferably, the antifoaming mechanism includes a toothed disc sleeved outside the stainless steel pipe body, a gear meshed on one side of the toothed disc, and a support block arranged at the bottom of the toothed disc and slidably connected to the electrolytic tank.

[0018] Preferably, a plurality of cleaning rubber rollers arranged in an annular array are fixedly connected to the inner wall of the toothed disc. The cleaning rubber rollers are made of rubber and have elasticity. Circular ring clamping blocks are fixedly connected to both sides of the toothed disc symmetrically.

[0019] Preferably, a connecting plate is fixedly connected to the top of the support block. The connecting plate is rotationally connected to the center of the gear. A control motor for driving the gear to rotate is fixedly arranged on the connecting plate. A fixed ring is fixedly arranged on the top of the support block near one side of the tooth disc. An annular groove for rotatably connecting with the annular block is formed in the fixed ring. A moving groove for slidably connecting with the moving block is formed in the bottom of the support block.

[0020] Preferably, electric telescopic rods are fixedly arranged on both symmetric sides of the connecting seat. The electric telescopic rods are fixedly connected to the support block.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] Through the cooperation of structures such as clamping blocks, clamping claws and driving components, the present invention facilitates the automatic clamping and fixing of the pipe body. By placing the stainless steel pipe body into the electrolytic tank, the fixing mechanism will automatically clamp according to its weight. The stainless steel pipe body is placed between two clamping blocks. The driving component drives the clamping claws to rotate, making the tops of the clamping blocks approach each other to achieve clamping. The rubber gasket inside the clamping block contacts the pipe body, playing a role in protection and anti-slip, and solving the problems that when the existing electrolytic device fixes the pipe body, it is difficult to fix stainless steel pipes with different diameters and lengths, and at the same time, it may leave indentations or scratches on the surface of the stainless steel pipe, affecting the surface quality after polishing.

[0023] Through the cooperation of structures such as a support plate, a driving block and a floating spring, the present invention facilitates the automatic driving and clamping of two clamping plates. By placing the stainless steel pipe body on the support plate, the support plate descends to drive the driving block to move downward. The inclined surface of the driving block squeezes the clamping claws, causing their tops to converge inward, driving the clamping blocks to approach each other, and clamping the pipe body through the rubber gasket. At this time, the support spring is compressed and the floating spring is inclined. After clamping, the control box starts the electrolytic tank to be powered on for polishing. After polishing is completed, the pipe body is lifted, and the support spring and the floating spring return to their original positions, and the clamping claws and the clamping blocks return to their original positions, facilitating the next use.

[0024] Through the cooperation of structures such as a tooth disc, a cleaning rubber roller and a gear, the present invention facilitates the rapid elimination of bubbles on the surface of the tank body. The defoaming mechanism is used to quickly remove the bubbles on the surface of the stainless steel pipe body during electrolytic polishing. The control motor drives the gear to rotate, driving the tooth disc to rotate, and the cleaning rubber roller rotates accordingly. The cleaning rubber roller is made of elastic rubber and is suitable for pipe bodies of different sizes. At the same time, the electric telescopic rod pushes the support block to move reciprocally, so that the cleaning rubber roller moves while rotating, realizing the efficient defoaming of the surface of the stainless steel pipe body.

Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] As Figures 1 to 8 shown, the present invention provides an electrolytic polishing device for semiconductor stainless steel pipes, including an electrolysis tank 1, a control box 11 fixedly arranged on the outer wall of the electrolysis tank 1, and a plurality of moving blocks 12 fixedly arranged at the bottom of the electrolysis tank 1. It further includes:

[0036] The stainless steel pipe body 2 is located inside the electrolysis tank 1 and is polished by the electrolyte in the electrolysis tank 1;

[0037] The fixing mechanism 3 is located inside the electrolysis tank 1 and is arranged in a linear array in multiple groups for fixing multiple stainless steel pipe bodies 2;

[0038] The defoaming mechanism 4 is on the same plane as the fixing mechanism 3 and is used to eliminate the bubbles on the stainless steel pipe body 2;

[0039] Among them, the fixing mechanism 3 includes a mounting plate 31, two clamping blocks 32 symmetrically arranged on both sides of the top of the mounting plate 31, clamping claws 33 fixedly arranged at the bottoms of the two clamping blocks 32, and a driving component 34 arranged at the center of the two clamping blocks 32 for driving the two clamping claws 33 to approach or move away from each other.

[0040] Adopting the above scheme: When using this device, first place the stainless steel pipe body 2 to be polished inside the electrolysis tank 1 and realize automatic clamping and fixing through the fixing mechanism 3. The fixing mechanism 3 can automatically adjust the clamping force according to the weight of the stainless steel pipe body 2 to ensure the stability and reliability of the clamping process. Specifically, the stainless steel pipe body 2 is placed between the two clamping blocks 32. The tops of the clamping blocks 32 approach or move away from each other under the control of the driving component 34. The driving component 34 drives the two clamping claws 33 to rotate at an angle, thereby driving the tops of the clamping blocks 32 to close inward to realize the clamping and fixing of the stainless steel pipe body 2. During the clamping process, the rubber gasket 321 installed on the inner side of the clamping block 32 is in direct contact with the stainless steel pipe body 2. The rubber gasket 321 can not only increase the clamping friction force to prevent the stainless steel pipe body 2 from sliding during the polishing process, but also effectively avoid surface scratches or damages caused by the direct contact between the clamping block 32 and the stainless steel pipe body 2, playing a good protective role. This design not only ensures the stability of the clamping, but also takes into account the protection of the surface of the stainless steel pipe body 2, ensuring the high efficiency and safety of the polishing process. In addition, the automated design of the fixing mechanism 3 makes the operation more convenient. The user only needs to place the stainless steel pipe body 2 at the designated position, and the device can automatically complete the clamping and fixing without manual intervention, greatly improving the work efficiency. At the same time, the replaceable design of the rubber gasket 321 also extends the service life of the device and reduces the maintenance cost. Overall, through the ingenious structural design and automated functions, this device realizes the efficient, precise and safe polishing treatment of the stainless steel pipe body 2.

[0041] As Figure 6 shown, the two clamping blocks 32 are arc-shaped. Rubber gaskets 321 are fixedly connected to the mutually approaching sides of the two clamping blocks 32. The rubber gaskets 321 are in contact with the stainless steel pipe body 2. The two clamping claws 33 are Z-shaped and are hinged to the mounting plate 31 at the centers;

[0042] The driving component 34 includes a pallet 341, a driving block 342 fixedly arranged at the bottom of the pallet 341, a support spring 343 fixedly installed at the center of the bottom of the driving block 342, and two floating springs 344 arranged at the bottoms of the two jaws 33. A chute 311 is formed on the mounting plate 31, and the pallet 341 slides along the chute 311. A connecting seat 35 is fixedly arranged on the surface of the mounting plate 31. Insertion grooves 351 are formed on both symmetric sides of the top of the connecting seat 35, and the floating springs 344 are snap-fitted and fixed with the insertion grooves 351.

[0043] Adopting the above solution: When using this device, first place the stainless steel pipe body 2 to be polished on the pallet 341. The pallet 341 descends under the action of gravity, driving the driving block 342 to move downward synchronously. The driving block 342 is designed with an irregular shape, and the side of its bottom in contact with the jaw 33 has an inclined structure with a larger upper part and a smaller lower part. When the driving block 342 moves downward, its inclined surface will squeeze the jaws 33 on both sides, forcing the jaws 33 to deflect at an angle, so that the tops of the jaws 33 move inward. The rotation of the jaws 33 further drives the clamping blocks 32 on both sides to approach each other, and the rubber gaskets 321 installed on the inner sides of the clamping blocks 32 come into contact with the surface of the stainless steel pipe body 2, realizing stable clamping of the pipe body. During the clamping process, the support spring 343 is in a compressed state due to the force, and at the same time, the two floating springs 344 are in an inclined state due to the deflection of the jaws 33. This design not only ensures the stability and reliability of clamping, but also can automatically adjust the clamping force according to the size and weight of the stainless steel pipe body 2, avoiding affecting the polishing effect due to over-tight or over-loose clamping. After the clamping and fixing are completed, start the electrolytic cell 1 through the control box 11 to make it energized inside, and use the electrolyte to polish the stainless steel pipe body 2 efficiently. During the polishing process, the device can maintain a stable clamping state to ensure uniform and efficient polishing. After the polishing is completed, move the stainless steel pipe body 2 upward to take it out. At this time, the support spring 343 and the floating springs 344 automatically reset after losing the external force, driving the jaws 33 and the clamping blocks 32 to return to the initial position, preparing for the next clamping operation. This design not only realizes rapid and accurate clamping of the stainless steel pipe body 2, but also improves the repeated use efficiency of the device through the automatic reset function of the spring structure. The use of the rubber gaskets 321 further protects the surface of the stainless steel pipe body 2, avoiding scratches or damages during the clamping process. The overall structure is simple and practical, the operation is convenient, it is suitable for the polishing requirements of stainless steel pipe bodies 2 with different sizes and weights, and significantly improves the efficiency and quality of the polishing operation.

[0044] Such as Figure 7As shown in the figure, the defoaming mechanism 4 includes a toothed disc 41 sleeved outside the stainless steel pipe body 2, a gear 42 meshed on one side of the toothed disc 41, and a support block 43 arranged at the bottom of the toothed disc 41 and slidably connected to the electrolysis tank 1. A plurality of cleaning rubber rollers 411 arranged in an annular array are fixedly connected to the inner wall of the toothed disc 41. The cleaning rubber rollers 411 are made of rubber material and have elasticity. Circular ring blocks 412 are fixedly connected to both symmetrical sides of the toothed disc 41. A connecting plate 431 is fixedly connected to the top of the support block 43. The connecting plate 431 is rotatably connected to the center of the gear 42. A control motor 421 for driving the gear 42 to rotate is fixedly arranged on the connecting plate 431. A fixed ring 432 is fixedly arranged on the top of the support block 43 near the toothed disc 41. A circular ring slot 4321 for rotatably connecting with the circular ring block 412 is formed on the fixed ring 432. A moving slot 433 for slidably connecting with the moving block 12 is formed at the bottom of the support block 43;

[0045] Electric telescopic rods 36 are fixedly arranged on both symmetrical sides of the connecting seat 35. The electric telescopic rods 36 are fixedly connected to the support block 43.

[0046] With the above scheme: During the electrolytic polishing process, the defoaming mechanism 4 is used to quickly remove the bubbles on the surface of the stainless steel pipe body 2 to ensure uniform and efficient polishing effect. The core working principle of the defoaming mechanism 4 is as follows: First, the control motor 421 starts, driving the gear 42 to rotate. The gear 42 meshes with the toothed disc 41, driving the toothed disc 41 to rotate synchronously. During the rotation of the toothed disc 41, the circular ring blocks 412 installed on its inner side slide along the circular ring slots 4321 on the fixed ring 432, enabling the toothed disc 41 to rotate smoothly. The cleaning rubber rollers 411 installed on the inner wall of the toothed disc 41 rotate accordingly. The cleaning rubber rollers 411 are made of high-elastic rubber material and can adapt to stainless steel pipe bodies 2 with different diameters, ensuring the versatility and flexibility of the defoaming operation. To further improve the defoaming effect, the device is also equipped with electric telescopic rods 36. The electric telescopic rods 36 are symmetrically distributed on both sides of the support block 43 and are designed to move in opposite directions. When the electric telescopic rods 36 start, they will simultaneously push the support block 43 to move reciprocally. This reciprocating motion combined with the rotational motion of the cleaning rubber rollers 411 enables the cleaning rubber rollers 411 to move horizontally along the surface of the stainless steel pipe body 2 while rotating. This combined motion mode can comprehensively cover the surface of the stainless steel pipe body 2, efficiently eliminate the bubbles generated during the polishing process, and avoid the interference of bubbles on the polishing quality. The rubber material of the cleaning rubber rollers 411 not only has good elasticity but also can effectively remove the bubbles without damaging the surface of the stainless steel pipe body 2. At the same time, the precise control of the electric telescopic rods 36 enables the movement range of the cleaning rubber rollers 411 to be adjustable, which can adapt to stainless steel pipe bodies 2 with different lengths and diameters, further improving the applicability and operation efficiency of the device.

[0047] Working principle and usage process of the present invention: When using this device, first place the stainless steel pipe body 2 on the support plate 341. Under the action of gravity, the support plate 341 descends, driving the driving block 342 to move downward synchronously. The inclined surface of the driving block 342 squeezes the clamping jaw 33, causing its bottom end to open outward and its top end to close inward, thereby pushing the two clamping blocks 32 closer to each other. The clamping blocks 32 quickly clamp and fix the stainless steel pipe body 2 through the rubber gasket 321. After the fixation is completed, start the control box 11 to energize the electrolysis tank 1 inside, and polish and grind the stainless steel pipe body 2 using the electrolyte. During the grinding process, control the motor 421 to drive the gear 42 to rotate, driving the toothed disc 41 and the cleaning rubber roller 411 to rotate synchronously. At the same time, the electric telescopic rod 36 pushes the cleaning rubber roller 411 to move while rotating, ensuring the rapid removal of the bubbles on the surface of the stainless steel pipe body 2 and avoiding the influence of bubbles on the polishing effect.
