Description

Technical Field

[0001] This utility model belongs to the field of reagent mixing technology, specifically relating to an electronic-grade chemical reagent mixing device. Background Technology

[0002] Electronic-grade chemical reagent mixing devices are one of the key supporting equipment in semiconductor manufacturing and microelectronics industries. They are used for the uniform mixing of high-purity chemical reagents. These devices are usually based on the principle of vortex oscillation. They use a vibrating plate to drive the container to rotate at high speed to form a vortex, thereby achieving thorough mixing of various reagents. The core requirements are high cleanliness, stability, and ease of operation. They are widely used in the sample pretreatment process in laboratories and production lines. Existing electronic-grade chemical reagent mixing devices mostly use fixed or snap-fit ​​multi-tube support sponge seats. When replacing them, it is necessary to manually remove the screws or pry the clips, which is a cumbersome and time-consuming process. The replacement of the support seat is complicated, time-consuming and inefficient. Utility Model Content

[0003] In view of this, the present invention provides an electronic-grade chemical reagent mixing device, which can be quickly installed through a quick disassembly mechanism. The simple operation of the quick disassembly mechanism, which allows for unlocking with a single press and installation with a single press, significantly shortens the replacement time of the multi-tube support sponge seat and greatly improves work efficiency and ease of operation.

[0004] To address the aforementioned technical problems, this utility model provides an electronic-grade chemical reagent mixing device, comprising a vortex mixer body and a slot disposed on its oscillating plate. A multi-tube support sponge seat is movably inserted into the slot. The slot is equipped with a quick-release mechanism for quickly assembling and disassembling the multi-tube support sponge seat. The quick-release mechanism includes sliding grooves disposed at both ends of the slot cavity, with limit blocks slidably connected in each groove. Limit grooves are provided at both ends of the lower side of the multi-tube support sponge seat corresponding to each limit block. The limit blocks are movably inserted into the adjacent limit grooves on the same side. Several distributed springs are provided between the limit blocks and their respective sliding grooves. The vortex mixer body is also equipped with a limiting component for limiting and fixing chemical reagent bottles, thus achieving quick installation. Through the simple operation of the quick-release mechanism—one-press unlocking and one-press installation—the replacement time of the multi-tube support sponge seat is significantly shortened, significantly improving work efficiency and ease of operation. The inner ends of the limit blocks are all inclined downwards from the outside to the inside, which facilitates automatic locking and installation.

[0005] The quick disassembly mechanism also includes reset slots respectively set at the front end of the limit block. The outer ends of the reset slots are inclined from the outside to the center of the multi-tube support sponge seat. The front end of the vortex mixer body's vibration plate is slidably connected to a top rod near each reset slot. The inner end of the top rod is respectively set to cooperate with the inclined surface of the adjacent reset slot on the same side, thus realizing convenient unlocking.

[0006] The quick-release mechanism also includes a connecting plate located at the outer ends of the two push rods, which allows for simultaneous control of the push rod movements on both sides.

[0007] The quick assembly and disassembly mechanism also includes rotating wheels that are rotatably connected to the inner end of the top rod. The outer arc surface of the rotating wheel is respectively set to cooperate with the inclined surface of the adjacent reset groove on the same side, which reduces friction and improves the smoothness of operation.

[0008] The front end of the oscillating plate of the vortex mixer body is equipped with a protective cover. The lower end of the protective cover is open, and the connecting plate is located inside the protective cover, which protects the mechanism inside and prevents accidental contact.

[0009] The limiting component includes fixed rods symmetrically arranged at both ends of the upper side of the vortex mixer body, and a sponge positioning frame is slidably connected between the two fixed rods, which can be adjusted to adapt to different bottle heights.

[0010] The limiting component also includes through-holes symmetrically arranged at both ends of the sponge positioning frame. Each through-hole at both ends of the sponge positioning frame is provided with a fixing cover. The inner cavity of each fixing cover is rotatably connected with a pawl. The outer arc surface of the fixing rod is provided with ratchet grooves evenly distributed along its axis. The pawls are respectively engaged with the corresponding ratchet grooves on the same side. Each fixing cover is provided with a spring piece, which abuts against the pawl located in the same fixing cover. That is, stepless fixing and anti-loosening are achieved through the pawl and ratchet structure.

[0011] The beneficial effects of the above-mentioned technical solution of this utility model are as follows: 1. When it is necessary to replace the multi-tube support sponge seat of different specifications, the user only needs to press the connecting plate inside the protective cover. The connecting plate will drive the top rods on both sides to move inward. The inner end of the top rod slides along the inclined surface of the reset groove through the rotating wheel, thereby causing the limit block to overcome the elastic force of the spring and slide out of the limit groove along the slide groove, thereby releasing the limit on the multi-tube support sponge seat. At this time, the multi-tube support sponge seat can be directly removed. When installing the new multi-tube support sponge seat, align the multi-tube support sponge seat with the slot and press down. At this time, the lower edge of the multi-tube support sponge seat will make inclined contact with the inner end of the limit block, and cause the limit block to overcome the elastic force of the spring and avoid it. After the multi-tube support sponge seat is fully inserted into the slot, the limit block will immediately reset under the action of the spring and be inserted and locked into the limit groove, realizing quick installation. Through the simple operation of the quick disassembly and assembly mechanism, the replacement time of the multi-tube support sponge seat is greatly shortened, and the work efficiency and operation convenience are significantly improved.

[0012] 2. Press down on the sponge positioning frame fitted on the fixed rod. The sponge positioning frame moves down, causing its auxiliary mechanism to move down synchronously. After the sponge positioning frame comes into contact with the chemical reagent bottle, it is fixed at the required height by the engagement of the pawl and the ratchet groove. The spring plate always applies pressure to the pawl to maintain the locked state, thereby adjusting the limit position according to the height of different reagent bottles.

[0013] 3. The connecting plate is located inside the protective cover, which can provide safety protection for the connecting plate and prevent user misoperation. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-6 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0017] This embodiment provides an electronic-grade chemical reagent mixing device, such as... Figure 1-6As shown: The device includes a vortex mixer body 100 and a slot on its oscillating plate. A multi-tube support sponge seat 200 is movably inserted into the slot. The slot is equipped with a quick-release mechanism for quick assembly and disassembly of the multi-tube support sponge seat 200. The quick-release mechanism includes a sliding groove 300 at both ends of the inner cavity of the slot. Each sliding groove 300 is slidably connected to a limiting block 301. Each of the lower ends of the multi-tube support sponge seat 200 is provided with a limiting groove 302 corresponding to each limiting block 301. Each limiting block 301 is movably inserted into the adjacent limiting groove 302 on the same side. Several springs 303 are distributed between each limiting block 301 and its corresponding sliding groove 300. The vortex mixer body 100 is also equipped with a limiting component for limiting and fixing chemical reagent bottles. The inner ends of the limiting blocks 301 are all inclined downwards from the outside to the inside.

[0018] When installing the new multi-tube support sponge seat 200, align the multi-tube support sponge seat 200 with the slot and press it down. At this time, the lower edge of the multi-tube support sponge seat 200 will make inclined contact with the inner end of the limiting block 301, and cause the limiting block 301 to overcome the elastic force of the spring 303 to avoid it. After the multi-tube support sponge seat 200 is fully inserted into the slot, the limiting block 301 will immediately reset under the action of the spring 303 and be inserted and locked into the limiting groove 302, realizing quick installation. Through the simple operation of the quick disassembly and assembly mechanism, the replacement time of the multi-tube support sponge seat is greatly shortened, and the work efficiency and operation convenience are significantly improved.

[0019] like Figure 1-5 As shown, the quick disassembly mechanism also includes reset slots 304 respectively disposed at the front end of the limiting block 301. The outer ends of the reset slots 304 are inclined from the outside to the center of the multi-tube support sponge seat 200. The front end of the vortex mixer body 100 is slidably connected to a push rod 305 near each reset slot 304. The inner end of the push rod 305 is respectively engaged with the inclined surface of the adjacent reset slot 304 on the same side. The quick disassembly mechanism also includes a connecting plate 306 disposed at the outer end of the two push rods 305. The quick disassembly mechanism also includes a rotating wheel 307 respectively rotatably connected to the inner end of the push rod 305. The outer arc surface of the rotating wheel 307 is respectively engaged with the inclined surface of the adjacent reset slot 304 on the same side.

[0020] When it is necessary to replace the multi-tube support sponge seat 200 of different specifications, the user only needs to press the connecting plate 306 inside the protective cover 400. The connecting plate 306 drives the top rods 305 on both sides to move inward. The inner end of the top rod 305 slides along the inclined surface of the reset groove 304 through the rotating wheel 307, thereby causing the limiting block 301 to overcome the elastic force of the spring 303 and slide outward along the slide groove 300 from the limiting groove 302, thereby releasing the limitation on the multi-tube support sponge seat 200.

[0021] like Figure 1-5 As shown, the front end of the oscillating plate of the vortex mixer body 100 is provided with a protective cover 400. The lower end of the protective cover 400 is open. The connecting plate 306 is located inside the protective cover 400, which can play a safety protection role for the connecting plate 306 and prevent user misoperation.

[0022] like Figure 1-6 As shown, the limiting component includes fixed rods 500 symmetrically arranged at both ends of the upper side of the vortex mixer body 100. A sponge positioning frame 501 is slidably connected between the two fixed rods 500. The limiting component also includes through openings 502 symmetrically arranged at both ends of the sponge positioning frame 501. Each end of the sponge positioning frame 501 is provided with a fixed cover 503 corresponding to each through opening 502. A pawl 504 is rotatably connected to the inner cavity of each fixed cover 503. Each fixed rod 500 has a ratchet groove 505 evenly distributed along its axial direction on its outer arc surface. The pawl 504 is movably engaged with the corresponding ratchet groove 505 on the same side. Each fixed cover 503 is provided with a spring piece 506. The spring piece 506 abuts against the pawl 504 located in the same fixed cover 503.

[0023] Press the sponge positioning frame 501 sleeved on the fixed rod 500. The sponge positioning frame 501 moves down, causing its auxiliary mechanism to move down synchronously. After the sponge positioning frame 501 comes into contact with the chemical reagent bottle, it is fixed at the required height by the engagement of the pawl 504 and the ratchet groove 505. The spring piece 506 always applies pressure to the pawl 504 to maintain the locked state, thereby adjusting the limiting position according to the height of different reagent bottles. When disassembly is required, simply press the convex plate at the lower end of the two pawls 504 to make the pawl 504 overcome the elastic force of the spring piece 506 and separate from the ratchet groove 505. At this time, the sponge positioning frame 501 can be removed.

[0024] The working principle of the electronic-grade chemical reagent mixing device provided by this utility model is as follows: When it is necessary to replace the multi-tube support sponge seat 200 of different specifications, the user only needs to press the connecting plate 306 inside the protective cover 400. The connecting plate 306 synchronously drives the two push rods 305 on both sides to move inward. The inner end of the push rod 305 slides along the inclined surface of the reset groove 304 through the rotating wheel 307, thereby causing the limiting block 301 to overcome the elastic force of the spring 303 and slide out of the limiting groove 302 along the sliding groove 300, thereby releasing the limitation on the multi-tube support sponge seat 200. At this time, the multi-tube support sponge seat 200 can be directly removed. When installing the new multi-tube support sponge seat 200, align the multi-tube support sponge seat 200 with the slot and press down. At this time, the lower edge of the multi-tube support sponge seat 200 will make inclined contact with the inner end of the limiting block 301. This causes the limiting block 301 to overcome the elastic force of the spring 303 and avoid it. After the multi-tube support sponge seat 200 is fully inserted into the slot, the limiting block 301 immediately resets under the action of the spring 303 and is inserted and locked into the limiting groove 302, realizing quick installation. Through the simple operation of the quick disassembly and assembly mechanism, the replacement time of the multi-tube support sponge seat is greatly shortened, and the work efficiency and operation convenience are significantly improved. At the same time, the sponge positioning frame 501 sleeved on the fixed rod 500 is pressed down, and the sponge positioning frame 501 moves down, driving its auxiliary mechanism to move down synchronously. After the sponge positioning frame 501 comes into contact with the chemical reagent bottle, it is fixed at the required height by the engagement of the pawl 504 and the ratchet groove 505. The spring piece 506 always applies pressure to the pawl 504 to maintain the locked state, thereby adjusting the limiting position according to the height of different specifications of reagent bottles.

[0025] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
