Description

Technical Field

[0001] This utility model relates to the field of diamond processing equipment technology, specifically to an etching and forming mechanism for processing diamond heating materials. Background Technology

[0002] Diamond heating materials are a new type of functional material developed based on the high thermal conductivity and high temperature resistance properties of diamond, and are widely used in semiconductors, lasers, high-power electronic devices, and other fields. During processing, diamond materials need to be precisely shaped using etching technology to form specific microstructures or electrode patterns. An etching forming machine is a device that uses chemical or physical methods to selectively remove material from the diamond surface, and typically includes an etching tank, a control system, a heating device, and a cleaning module.

[0003] In the processing of diamond heating materials, the etching pool is one of the core components, mainly used to hold the etching solution (such as strong acid, strong oxidant, or plasma solution), which removes the material from the diamond surface through chemical reaction or electrochemical action. Due to the extremely strong chemical inertness of diamond, traditional machining methods struggle to achieve high-precision etching. The etching pool, however, provides a controllable chemical corrosion environment, ensuring processing accuracy and surface quality. Furthermore, the etching pool can optimize the etching effect by adjusting temperature, concentration, and reaction time.

[0004] Traditional etching baths produce residual floating matter after prolonged use. This mainly includes carbon particles remaining due to incomplete decomposition of reactive diamond (C) in strongly oxidizing etching solutions (such as a mixture of nitric acid and sulfuric acid) or plasma environments. These particles remain suspended on the surface or in the solution, affecting etching uniformity and even causing workpiece surface contamination. Existing technologies typically rely on manual cleaning or shutdown for solution replacement, which is inefficient and disrupts production continuity. Therefore, an etching and shaping mechanism for processing diamond heating materials is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an etching and forming mechanism for processing diamond heating materials. It has the advantage of automatically cleaning the etching pool, thus solving the problem of low diamond etching efficiency caused by the need for manual cleaning of suspended matter in the etching solution in existing technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an etching and forming mechanism for processing diamond heating materials, comprising an etching pool, wherein a partition plate is provided inside the etching pool, the partition plate dividing the interior of the etching pool into an etching chamber for etching diamond and a draining chamber for cleaning waste, and a drain pipe for draining waste is connected to the draining chamber.

[0007] The top of the etching pool is equipped with a cleaning component for automatically cleaning suspended matter in the etching solution, and the outside of the pool is equipped with an auxiliary component to assist the cleaning component in agitating the suspended matter in the etching solution.

[0008] The cleaning assembly includes a transmission component mounted on an etching pool and two connecting shafts spaced apart on the etching pool. One of the connecting shafts is linked to the transmission component via a linkage component. The shafts of the two connecting shafts are spaced apart by two pulleys. A transmission belt is tensioned between the pulleys on the two connecting shafts. At least one elastic scraper for cleaning suspended matter is provided on each of the two transmission belts.

[0009] Furthermore, the partition plate is an L-shaped bent plate, and its bottom is sealed to the inside of the etching pool to separate it from the etching solution.

[0010] Furthermore, the top of the L-shaped bending plate is connected by an inverted V-shaped bending plate with a central protrusion and inclined ends via a sloping plate, which is used to block the etching solution.

[0011] Furthermore, the auxiliary component includes an air pump installed on the etching tank, the output end of the air pump is connected to a connecting pipe, the other end of the connecting pipe extends into the interior of the etching tank and is connected to at least one branch pipe, the outlet of the branch pipe is immersed in the etching solution.

[0012] Furthermore, a gas diffuser is provided at the outlet of the branch pipe, including a cavity frustum connected to the branch pipe, and multiple exhaust pipes immersed in the etching solution are provided on the cavity frustum.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] I. The etching and forming mechanism for processing diamond heating materials is equipped with a cleaning component. During the etching process, when suspended particles such as carbon particles and etching byproducts generated by the reaction on the diamond surface float on the liquid surface, the scraper of the cleaning component moves with the transmission belt to push the suspended particles into the drain chamber for automatic collection. This avoids the need for manual cleaning or stopping the machine to change the liquid, and increases the etching effect and etching efficiency.

[0015] II. This etching and forming mechanism for processing diamond heating materials utilizes auxiliary components to agitate the etching solution with air bubbles, preventing particle deposition and improving scraping efficiency. It eliminates the need for manual slag removal during machine downtime, increasing production efficiency. It also promptly removes suspended matter, preventing secondary adhesion that could affect etching precision, reducing impurity accumulation, and lowering the frequency of solution changes.

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-5This embodiment of an etching and forming mechanism for processing diamond heating materials includes an etching pool 1. The etching pool 1 has a partition plate 11 inside, which divides the interior of the etching pool 1 into an etching chamber 12 for etching diamond and a drain chamber 13 for cleaning waste. A drain pipe 131 for draining waste is connected to the drain chamber 13. A cleaning component 2 for automatically cleaning suspended matter in the etching solution is provided at the top of the etching pool 1, and an auxiliary component 3 for assisting the cleaning component 2 in agitating suspended matter in the etching solution is provided outside the pool. The cleaning component 2 includes a transmission component 21 on the etching pool 1 and two connecting shafts 23 spaced apart on the etching pool 1. One connecting shaft 23 is linked to the transmission component 21 by a linkage component 22. Two pulleys 24 are spaced apart on the rods of the two connecting shafts 23. A transmission belt 25 is tensioned between the pulleys 24 on the two connecting shafts 23, and at least one elastic scraper 26 for cleaning suspended matter is provided on each of the two transmission belts 25. The etching chamber 12 for diamond etching and the waste collection and drainage chamber 13 are separated by a partition plate 11. The cleaning assembly 2 is driven by a transmission component 21, such as a motor, which in turn drives two connecting shafts 23 to rotate via a linkage component 22, such as a gear / belt. Pulleys 24 are mounted on the two shafts, and a transmission belt 25 drives an elastic scraper 26 to circulate and scrape away suspended matter from the surface of the etching solution. A gas pump 31 introduces gas, such as nitrogen or air, into the etching solution. Bubbles are generated through a branch pipe 33 and a gas diffuser 34, agitating the etching solution and causing suspended matter to float to the surface.

[0024] The technical effects of the above embodiments are as follows: During the etching process, suspended matter such as carbon particles and etching byproducts generated by the reaction on the diamond surface floats on the liquid surface. The scraper 26 of the cleaning component 2 moves with the transmission belt 25, pushing the suspended matter towards the drain chamber 13. The air bubbles of the auxiliary component 3 agitate the etching solution, preventing particle deposition and improving scraping efficiency.

[0025] It enables manual slag removal without stopping the machine, improving production efficiency, timely removal of suspended solids, avoiding secondary adhesion that affects etching accuracy, reducing impurity accumulation, and lowering the frequency of liquid replacement.

[0026] As a preferred technical solution in this embodiment: the partition plate 11 is an L-shaped bent plate, and its bottom is sealed to the inside of the etching pool 1 to separate it from the etching liquid. The L-shaped structure forms a physical barrier, and impurities in the etching liquid can only enter the drain chamber 13 through the liquid surface, without leakage at the bottom.

[0027] As a preferred technical solution in this embodiment: the top of the L-shaped bending plate is connected to an inverted V-shaped bending plate with a central protrusion and inclined ends via an inclined plate, which is used to block the etching solution. When suspended matter is pushed to the inverted V-shaped plate by the scraper 26, it is guided by the inclined surface to slide into the drain chamber 13. The protrusion prevents cross-contamination caused by etching solution splashing or turbulence.

[0028] As a preferred technical solution in this embodiment: the auxiliary component 3 includes an air pump 31 installed on the etching tank 1. The output end of the air pump 31 is connected to a connecting pipe 32. The other end of the connecting pipe 32 extends into the interior of the etching tank 1 and is connected to at least one branch pipe 33. The outlet of the branch pipe 33 is immersed in the etching solution. The air pump 31 supplies air to the etching solution through the connecting pipe 32. A gas diffuser 34, such as a microporous aerator, is installed at the end of the branch pipe 33.

[0029] As a preferred technical solution in this embodiment: a gas diffuser 34 is provided at the outlet of the branch pipe 33, including a hollow frustum connected to the branch pipe 33, and multiple exhaust pipes immersed in the etching solution are provided on the hollow frustum. After the gas enters the cavity, it is evenly distributed to each exhaust pipe, forming a dense bubble flow, avoiding insufficient local disturbance and enhancing the disturbance effect. The frustum structure can be made of PTFE or PVDF material, which is resistant to etching solution corrosion.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
