Description

Technical Field

[0001] This application relates to the field of cutting disc cleaning technology, and more specifically, to a cutting disc pre-cleaning platform. Background Technology

[0002] Slurry wire EDM is a processing method for hard and brittle materials such as third-generation semiconductors. Its principle is as follows: a high-speed reciprocating metal wire (i.e., a wire saw) carries cutting fluid containing abrasive particles into the kerf. Under the pressure and speed of the wire saw, the free abrasive particles roll and cut the workpiece, thus achieving material separation. In existing technologies, the post-cutting unloading and pre-cleaning processes heavily rely on manual labor. The process typically includes: manually pouring hot water to remove adhesive, manually unloading the workpiece and inserting cutting disc inserters, cleaning with kerosene and rinsing with clean water on a per-insertion basis, and finally transferring to ultrasonic cleaning.

[0003] However, the above-mentioned manual operation method has many drawbacks: since the degumming process relies on manually pouring hot water, there is not only a risk of scalding, but also the hot water temperature and pouring position are difficult to control precisely, resulting in long degumming time and low efficiency. This inefficient degumming process directly increases the difficulty of cutting the sheet, which can easily lead to quality defects such as edge chipping and sheet cracking, and ultimately seriously affect the product yield and output quality.

[0004] Therefore, how to improve the degumming efficiency during the cleaning process of cutting discs has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a cutting disc pre-cleaning platform to improve the degumming efficiency during the cutting disc cleaning process.

[0020] In some embodiments, the platform body and the platform backplate are an integral structure;

[0021] Alternatively, the platform backplate is snapped into connection with the platform body.

[0022] The cutting disc pre-cleaning platform provided in this application includes a platform body, a heating device, and a kerosene circulation system. The platform body is equipped with a heated degumming tank, a clean water unloading tank, and a kerosene cleaning tank. All three tanks are used for immersion cleaning of the cutting discs.

[0030] 200 is a heating device;

[0031] 300 is a kerosene storage container, 310 is a filter device, and 320 is a circulation pipeline. Detailed Implementation

[0032] The core of this application is to disclose a cutting disc pre-cleaning platform to improve the degumming efficiency during the cutting disc cleaning process.

[0033] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the utility model as described in the claims. Additionally, the complete contents of the structures represented in the embodiments below are not limited to those necessary for the solution of the utility model as described in the claims. It should be noted that, for ease of description, only the parts relevant to the utility model are shown in the drawings. Unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0034] In existing technologies, the degumming process during the pre-cleaning of cutting discs has significant drawbacks: Since the degumming tank lacks heating, manual hot water pouring is required. This method not only poses a risk of burns but also makes precise control of the hot water temperature and pouring position difficult, resulting in low degumming efficiency. This inefficient degumming process directly increases the difficulty of unloading the cutting discs, easily leading to quality defects such as edge chipping and breakage, ultimately severely impacting product yield. Similarly, existing technologies have shortcomings in the kerosene cleaning process: due to the lack of dedicated cleaning containers, operators must hold the cutting disc and repeatedly rinse it inside the kerosene drum. This method results in continuous contact with the cutting disc, easily causing edge chipping and breakage; simultaneously, prolonged exposure to kerosene in the work environment poses health risks due to its pungent odor. From an overall process perspective, existing technologies lack an integrated work platform: the unloading, kerosene cleaning, and pre-cleaning processes are scattered across different workstations, requiring manual work arrangements and material handling. This fragmented work mode leads to chaotic material stacking on-site, increases unnecessary handling steps, reduces overall work efficiency, and introduces additional safety risks.

[0035] To address the aforementioned issues of low degumming efficiency, high operational risks, and discontinuous processes, this application discloses a cutting disc pre-cleaning platform. This platform integrates functional stations for heating degumming, water treatment, and kerosene cleaning, enabling continuous and integrated pre-cleaning operations on cutting saws equipped with cutting discs, thereby effectively solving various technical problems in the prior art.

[0036] Specifically, in combination Figures 1-4The cutting disc pre-cleaning platform disclosed in this application includes a platform body 100, a heating device 200, and a kerosene circulation system. The platform body 100 is equipped with a heating degumming tank 101, a clean water loading tank 102, and a kerosene cleaning tank 103. All three tanks can be used for immersion cleaning of the cutting discs. Specifically, the heating degumming tank 101 is used to degumme the cutting discs, the kerosene cleaning tank 103 is used to clean the cutting discs with kerosene, and the clean water loading tank 102 is used to clean the cutting discs with clean water. The heating device 200 is installed on the platform body 100 and is used to heat and maintain the temperature of the heating degumming tank 101, thereby achieving… The degumming and unloading process ensures degumming efficiency. The kerosene circulation system includes a kerosene storage container 300, a filter device 310, and a circulation pump. The kerosene cleaning tank 103, filter device 310, kerosene storage container 300, and circulation pump are sequentially connected through a circulation pipeline 320 to form a closed kerosene circulation loop. The kerosene in the kerosene cleaning tank 103 can be recycled and reused through the kerosene circulation loop. Specifically, the kerosene is filtered by the filter device 310 and then recycled back into the kerosene storage container 300 to ensure kerosene quality. When needed, the kerosene in the kerosene storage container 300 is drawn by the circulation pump and transported to the kerosene cleaning tank 103 for reuse, thereby reducing the amount of kerosene used and lowering costs.

[0037] Compared to existing technologies, the cutting disc pre-cleaning platform disclosed in this application integrates the heating degumming tank 101, the kerosene cleaning tank 103, and the clean water unloading tank 102 into the platform body 100, realizing integrated continuous operation of cutting disc unloading and cleaning. This application fundamentally changes the flow of cutting disc pre-cleaning operations, transforming the operation process from discrete to streamlined. All processes can be completed and stored within the cutting disc pre-cleaning platform, thereby eliminating inefficient steps such as secondary handling of the cutting saw, manual hot water degumming, and reciprocating handling for kerosene cleaning. This significantly improves operational efficiency and reduces the risk of cutting discs falling and colliding during manual handling, ensuring product turnover safety. In terms of product quality, the cutting disc pre-cleaning platform disclosed in this application can adopt full-process immersion cleaning, avoiding the impact and damage to the cutting discs caused by water flow, manual contact, and unstable operation in traditional rinsing methods, effectively reducing the defect rate. The kerosene circulation loop also significantly reduces kerosene consumption, lowering costs.

[0038] Specifically, the filtration device 310 may include a filter screen disposed between the drain outlet of the kerosene cleaning tank 103 and the kerosene storage container 300. The filter screen is connected to both the kerosene cleaning tank 103 and the kerosene storage container 300 via a circulation pipe 320. The filter screen may be made of materials such as stainless steel or polypropylene, and this application does not limit its use. The volume of the kerosene storage container 300 can be adjusted according to actual conditions, for example, set to 60L. The kerosene can also be filtered through the kerosene storage container 300 for sedimentation. In addition to the circulation pipe 320, the kerosene cleaning tank 103 may also be equipped with a normal sewage discharge pipe for convenient cleaning and sewage discharge of the kerosene cleaning tank 103.

[0039] To reduce safety hazards, the heating device 200 can be built into the interlayer space of the platform body 100, thereby effectively preventing direct contact between operators and the heating device 200 and improving operational safety. The heating device 200 can be controlled by a control panel for heating temperature and heating time, and the control panel can be installed on the platform body 100 and electrically connected to the heating device 200.

[0040] Specifically, the heating device 200 may include an electric heating tube, a coil heat exchanger, or a heating rod disposed at the bottom of the heating degumming tank 101. For example, in some embodiments, the heating device 200 is a concealed dual heating rod built into the interlayer space inside the platform body 100, with a maximum power of up to 3000W, to effectively ensure heating efficiency and prevent workers from contacting the heating rod, thereby fundamentally improving the efficiency and safety of the degumming and sheet removal process.

[0041] In some embodiments, the outer wall of the heating degumming tank 101 is covered with thermal insulation material to isolate and insulate the heating degumming tank 101, reduce the energy consumption of the heating device 200, and reduce the impact of high temperature on the kerosene in the kerosene cleaning tank 103; at the same time, it can reduce the surface temperature of the outer wall of the platform body 100, reduce the risk of burns to workers, and reduce unnecessary temperature rise in the workshop. Specifically, the thermal insulation material can be glass wool, rock wool, etc., and this application does not limit it.

[0042] Combination Figure 1 and Figure 2 Along the extension direction of the platform body 100, the heating degumming tank 101, the clean water unloading tank 102, and the kerosene cleaning tank 103 can be arranged in sequence. The arrangement of separating the heating degumming tank 101 and the kerosene cleaning tank 103 by the clean water unloading tank 102 can ensure that the working temperature of the kerosene cleaning tank 103 is not affected by the adjacent high-temperature heating degumming tank 101, fundamentally eliminating the fire hazard caused by excessive kerosene volatilization and effectively ensuring safety. At the same time, this arrangement also makes it convenient to directly put the cutting disc into the clean water unloading tank 102 for cleaning after degumming and unloading.

[0043] To improve the cleaning effect, at least one of the heating degumming tank 101, the clean water unloading tank 102, and the kerosene cleaning tank 103 is equipped with a spraying device. The spraying device enables each cleaning tank to not only clean the cutting disc by immersion, but also to perform uniform and automated spraying cleaning by fluid impact.

[0044] After the cutting disc is removed from the tank, it is supported by a cutting disc holder. In some embodiments disclosed in this application, both the water tank 102 and the kerosene cleaning tank 103 can be used to place a carrying basket, and multiple cutting disc holders can be placed in the carrying basket. This allows the cutting discs to be transferred in batches between the water tank 102 and the kerosene cleaning tank 103 and cleaned in a centralized manner, reducing the turnover steps from the cutting disc to the cutting disc holder and then to the carrying basket. Furthermore, in the kerosene cleaning tank 103, the cutting disc only needs to be soaked and rinsed as a whole, eliminating the need for the tedious process of manually cleaning each cutting disc in the cutting disc holder. This not only greatly improves the cleaning efficiency but also significantly reduces the risk of the cutting disc colliding and falling.

[0045] For example, to accommodate the flower basket, the length and width of the water cutting trough 102 can be designed to be 600mm × 500mm, allowing the cutting operation to be completed directly in it; similarly, the kerosene cleaning trough 103 is also designed to accommodate the flower basket, and its depth can be set to 350mm based on the 200mm cutting disc plug height, thus satisfying both immersion cleaning and reserving space for the reciprocating movement of the flower basket, and providing possibilities for subsequent modifications.

[0046] Combination Figure 1 In some embodiments disclosed in this application, the heating degumming tank 101 is equipped with a first cover plate 120, which is used to seal the heating degumming tank 101 to achieve a heat preservation function. For safe operation, a heat-insulated handle 121 is provided on the first cover plate 120. This heat-insulated handle 121 effectively isolates the high-temperature conduction of the first cover plate 120 through heat insulation treatment, ensuring that operators will not be burned when handling the first cover plate 120, thereby improving operational safety. The clear water flaking tank 102 is equipped with a second cover plate 130, and the kerosene cleaning tank 103 is equipped with a third cover plate 140. The third cover plate 140 is used to isolate kerosene, reduce kerosene evaporation, and protect the health of operators. Both the second cover plate 130 and the third cover plate 140 are equipped with perforated handrails. Operators can flexibly insert or remove positioning pins, blocks, or special clamps into the perforated handrails. After removal, the flatness of the entire platform body 100 can be improved, thereby accommodating the placement of various products and materials on the platform body 100.

[0047] Combination Figure 1 and Figure 2The platform body 100 is a tabletop structure. The heating degumming tank 101, the clean water unloading tank 102, and the kerosene cleaning tank 103 are all located on the top of the platform body 100. A platform back plate 110 is provided on one side of the top of the platform body 100, with its top extending above the top surface of the platform body 100. The platform back plate 110 can be reliably connected to the platform body 100 by welding, snap-fitting, or other methods. Alternatively, the platform back plate 110 and the platform body 100 can be an integral structure formed by casting or other methods. This serves to isolate water flow from the surface of the platform body 100, preventing water contamination; it also prevents products, materials, or tools from accidentally falling into the gap between the platform body 100 and the wall or other equipment during operation. For example, the total height of the platform body 100 is 1000mm, and the platform back plate 110 extends 200mm beyond the top surface of the platform body 100. In addition, the platform backplate 110 can reserve corresponding holes and other structures for wiring, water supply and drainage operations according to the circuit and pipeline layout on site.

[0048] In a specific pre-cleaning process for silicon carbide cutting discs, the cutting discs, along with the cutting saw, are transported by a transfer vehicle to the pre-cleaning workshop after wire cutting and placed in the heated degumming tank 101 of the cutting disc pre-cleaning platform. Clean water is added to the heated degumming tank 101 through a water supply device until it covers the cutting saw. The water in the heated degumming tank 101 is heated to 100°C and left to stand for 5-10 minutes before manual degumming and unloading. Before unloading, the carrying basket and cutting disc retainer must be placed in the clean water unloading tank 102, with the water level in the tank 102 exceeding the height of the cutting disc retainer by 200mm. Then, the operator can remove the cutting blades from the cutting saw and insert them into the cutting blade holders in sequence. After the single cutting saw finishes cutting the blades, the carrying basket is placed in the kerosene cleaning tank 103 for soaking, pouring, or reciprocating pre-cleaning. Soaking involves immersing the entire carrying basket in the kerosene tank, allowing the kerosene to dissolve stubborn oil stains by letting it stand. Pouring involves continuously spraying kerosene onto the cutting blades in the carrying basket, using the flowing liquid to quickly rinse away surface dirt. Reciprocating involves moving the carrying basket up and down or left and right in the kerosene, using a combination of agitation and rinsing force to achieve more efficient cleaning. After the kerosene is used for the day, it is discharged through the circulation pipeline 320 to the kerosene storage container 300 for secondary filtration and closed treatment to reduce the impact on the working environment. When it is used again, it is extracted by a circulation pump. After the kerosene cleaning is completed, the operator can remove the carrying basket for the next cleaning step without changing the carrying tool.
