Abstract
Description
Technical Field
[0001] This utility model relates to the field of stainless steel pipe processing technology, specifically a semiconductor-grade stainless steel pipe cleaning device. Background Technology
[0002] After machining, welding and other processes, precision stainless steel tubes in the semiconductor industry will have a lot of scratches and polishing marks on their surface. Therefore, surface treatment of precision stainless steel tubes in the semiconductor industry is one of the effective ways to extend their service life. Among them, surface passivation is one of the commonly used surface treatment methods for metal parts. After passivation, the tubes need to be cleaned of the passivation liquid remaining on the surface of the tubes.
[0003] The pipe fitting cleaning equipment currently equipped with pipe fitting limiting structures, such as the stainless steel pipe fitting hydraulic clamping and beveling machine disclosed in announcement number CN114799351B, guides and limits the slider through a top plate, and drives the slider to move by rotating a turntable. It uses an iris-like clamping mechanism for the slider to hold the sliding, and relies entirely on the mutual abutment of two groove structures to drive the limiting method. Its stability and working accuracy still have room for improvement, and it cannot meet the processing requirements of precision stainless steel pipes in the semiconductor industry. Utility Model Content
[0004] The purpose of this invention is to provide a semiconductor-grade stainless steel tube cleaning device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solutions:
[0006] A semiconductor-grade stainless steel tube cleaning device, comprising:
[0007] A support structure, the support structure including a base frame;
[0008] A shower structure, which is fixedly installed above the base frame;
[0009] The limiting structure comprises two sets, each including a base ring. The two sets of base rings are fixedly installed at the front and rear ends of the base frame. A conical toothed ring is rotatably installed on one edge of the side surface of the base ring. Several bevel gears that mesh with the conical toothed ring are rotatably installed at equal angles on the side surface of the base ring. An internal threaded hole is opened in the middle of the bevel gear, and a lead screw is screwed into the internal threaded hole.
[0010] Furthermore, the support structure also includes:
[0011] The base is fixedly installed on the upper edges of the front and rear sides of the base frame by means of corner brackets;
[0012] The base has four support legs, which are fixedly installed at the four corners of the bottom side of the base.
[0013] Furthermore, the support structure also includes:
[0014] A drainage hopper is fixedly installed at the bottom opening of the base frame;
[0015] Splash-proof side panels, the number of which is two, are fixedly installed on both sides of the opening on the base frame.
[0016] Furthermore, the shower structure includes:
[0017] A multi-port pipe, wherein several base blocks are fixedly connected to the bottom side of the multi-port pipe;
[0018] Spray nozzles: Several spray nozzles are fixedly installed at equal angles on the bottom side of the base block, and the spray nozzles are interconnected with the multi-port pipe.
[0019] The base block has support columns fixedly installed at both ends, and one end of the support column is fixedly connected to the inner surface of the splash guard side plate.
[0020] Furthermore, the limiting structure also includes:
[0021] The support column is fixedly installed on the bottom side of the base ring, and the lower end of the support column is fixedly installed on the upper surface of the base.
[0022] An external toothed ring, which is fixedly sleeved on the outer surface of a tapered toothed ring;
[0023] Gear, wherein the gear meshes with an external gear ring;
[0024] A drive motor is fixedly installed below the base, and the output end of the drive motor is fixedly connected to the gear.
[0025] Furthermore, the limiting structure also includes:
[0026] A wheel frame, which is fixedly installed at one end of a lead screw;
[0027] An external rotor motor, which is fixedly mounted in the middle of the wheel frame;
[0028] The rubbing wheel is fixedly sleeved on the outer surface of the outer rotor motor.
[0029] Compared with the prior art, the beneficial effects of the present invention are:
[0030] 1. The steel pipe to be cleaned is passed through the holes inside the two sets of base rings in sequence. The rotation of the outer gear ring drives each bevel gear synchronously. Then, the screw is rubbed inward by the internal thread hole to abut and center the side surface of the pipe. It can adapt to various outer diameter pipes within a certain range. At the same time, compared with the traditional iris-like synchronous drive clamping structure, the clamping and limiting structure adopts gear and thread drive, which has higher stability and precision.
[0031] 2. The drive motor rotates the gears, which in turn rotate the conical gear ring through the external gear ring, thereby simultaneously rotating several bevel gears. This controls the synchronous movement of each lead screw, causing each rubbing wheel to abut against the outer surface of the pipe fitting. The external rotor motor is then started, driving the rubbing wheels to rotate. Each rubbing wheel is in a 30-degree inclined state relative to the cross-section of the clamped pipe fitting. This allows the rubbing wheels to rub the pipe fitting while it is moving forward, and also to use a component force to rub the pipe fitting to rotate. This causes the pipe fitting to move in a rotating posture, ensuring that the outer surface of the pipe fitting is sprayed and rinsed by the rinsing structure, reducing cleaning dead spots and improving the cleaning effect.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0039] Please see Figure 1-5 In this embodiment of the present invention, a semiconductor-grade stainless steel tube cleaning device includes a support structure 1, a rinsing structure 2, and a limiting structure 3. The support structure 1 includes a base frame 101; the rinsing structure 2 is fixedly installed above the base frame 101; the limiting structure 3 consists of two sets, each including a base ring 301. The two sets of base rings 301 are fixedly installed at the front and rear ends of the base frame 101. A conical toothed ring 303 is rotatably installed on one edge of the side surface of the base ring 301. Several bevel gears 307 that mesh with the conical toothed rings 303 are rotatably installed at equal angles on the side surface of the base ring 301. An internal threaded hole 308 is opened in the middle of the bevel gear 307, and a lead screw 309 is screwed into the internal threaded hole 308.
[0040] Specifically, the steel pipe to be cleaned is passed through the holes inside the two sets of base rings 301 in sequence. The rotation of the external gear ring 304 synchronously drives each bevel gear 307, and then the internal threaded hole 308 is used to rub the screw 309 inward to slide it inward, so as to abut and center the side surface of the pipe fitting. It can adapt to various outer diameter pipe fittings within a certain range. At the same time, compared with the traditional iris-like synchronous drive clamping structure, the clamping and limiting structure adopts gear and thread drive, which has higher stability and precision.
[0041] Example 1
[0042] like Figure 2 As shown, in this embodiment, the support structure 1 also includes a base 102, support legs 103, a drainage hopper 104, and splash guards 105. The base 102 is fixedly installed on the upper edges of the front and rear sides of the base frame 101 by corner brackets; there are four support legs 103, which are fixedly installed at the four corners of the bottom side of the base 102; the drainage hopper 104 is fixedly installed at the opening on the bottom side of the base frame 101; there are two splash guards 105, which are fixedly installed on the two sides of the opening on the top side of the base frame 101.
[0043] In this embodiment, the splash guards 105 prevent the sprayed water from splashing out on both sides above the base frame 101, and the sprayed water is collected and discharged by the base frame 101 and the drainage hopper 104.
[0044] like Figure 3As shown, in this embodiment, the shower structure 2 includes a multi-port pipe 201, spray nozzles 203, and support columns 204. Several base blocks 202 are fixedly connected to the bottom side of the multi-port pipe 201. Several spray nozzles 203 are fixedly installed at equal angles on the bottom side of the base blocks 202, and the spray nozzles 203 are interconnected with the multi-port pipe 201. Support columns 204 are fixedly installed at both ends of the base blocks 202, and one end of the support column 204 is fixedly connected to the inner surface of the splash guard side plate 105.
[0045] In practice, the pipe travels from below the base block 202. During the rotation of the pipe, the cleaning fluid is introduced into each multi-port pipe 201 through the water supply structure connected to the upper end of the multi-port pipe 201, and then sprayed downwards through the spray nozzle 203 to rinse the pipe.
[0046] Example 2
[0047] Based on Embodiment 1, in order to supplement the specific method of clamping the pipe by the limiting structure 3, which was not mentioned in Embodiment 1, and the specific movement of the pipe after being clamped by the limiting structure 3.
[0048] like Figure 4-5 As shown, in this embodiment, the limiting structure 3 further includes a support column 302, an external gear ring 304, a gear 305, a drive motor 306, a wheel frame 310, an external rotor motor 311, and a rubbing wheel 312. The support column 302 is fixedly installed on the bottom side of the base ring 301, and the lower end of the support column 302 is fixedly installed on the upper surface of the base 102. The external gear ring 304 is fixedly sleeved on the outer surface of the conical gear ring 303. The gear 305 meshes with the external gear ring 304. The drive motor 306 is fixedly installed below the base 102, and the output end of the drive motor 306 is fixedly connected to the gear 305. The wheel frame 310 is fixedly installed on one end of the lead screw 309. The external rotor motor 311 is fixedly installed in the middle of the wheel frame 310. The rubbing wheel 312 is fixedly sleeved on the outer surface of the external rotor motor 311.
[0049] In practice, the drive motor 306 rotates the gear 305, which in turn rotates the conical gear ring 303 through the external gear ring 304, thereby simultaneously rotating several bevel gears 307. This controls the synchronous movement of each lead screw 309, causing each rubbing wheel 312 to abut against the outer surface of the pipe fitting. The external rotor motor 311 is then started, driving the rubbing wheels 312 to rotate. Each rubbing wheel 312 is in a 30-degree inclined state relative to the cross-section of the clamped pipe fitting, so that while rubbing the pipe fitting, the rubbing wheel 312 can also use a component force to rub the pipe fitting while it is moving forward, causing the pipe fitting to move in a rotating posture. This ensures that the outer surface of the pipe fitting is sprayed and rinsed by the rinsing structure 2, reducing cleaning dead corners and improving the cleaning effect.
