Description

Technical Field

[0002] Silicon wafer slicing machines use diamond or tungsten wire for cutting. The surface of the cutting wire is coated with electroplated abrasive particles, while the main wire is made of diamond or tungsten wire. During the actual slicing process, the cutting wire contacts the silicon rod and reciprocates with the aid of cutting fluid, cutting the silicon rod into silicon wafers of various specifications. The abrasive on the surface of the cutting wire is affected by various factors such as cutting impurities, silicon sludge, and deposited impurities, which will affect the cutting effect, silicon wafer quality, wire breakage rate, color difference, and wafer thickness.

[0041] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the scope of protection of this application.

[0042] This application provides a wire cleaning device, which is applied to a silicon wafer slicing machine and is used to clean the wires online in real time before the wires cut the material.

[0043] refer to Figures 1-3 The cutting line cleaning device includes a cleaning mechanism 101.

[0044] The cleaning mechanism 101 includes a cleaning chamber 1011. Before entering the cutting area for cutting, the cutting line 200 passes through the cleaning chamber 1011. The extension direction of the cutting line 200 is perpendicular to the vertical direction (z-axis shown in the figure).

[0045] The cleaning chamber 1011 can release negative ions. The negative ions can actively adsorb positively charged particles in the air and on the surface of the cutting line 200. After the negative ions combine with the positively charged particles, they will form larger particles. Due to their own gravity, these particles will settle to the bottom of the cleaning chamber 1011, reducing the concentration of suspended particulate matter in the air while ensuring the cleanliness of the surface of the cutting line 200.

[0046] The cutting line cleaning device also includes: a blower 103.

[0047] The cleaning chamber 1011 includes an air inlet 1012, which is connected to the air supply duct of the fan 103. The fan 103 is used to deliver airflow with preset air pressure and preset air volume into the cleaning chamber 1011. The airflow direction is parallel to the vertical direction (z-axis shown in the figure), thereby forming a directional airflow in the cleaning chamber 1011. This directional airflow is used to flush the surface of the cutting line 200, thereby cleaning away impurities on the surface of the cutting line 200; at the same time, it can also flush away particles that have combined with negative ions but have not completed sedimentation.

[0048] The cutting wire cleaning device provided in this application embodiment uses a dual approach of directional airflow in the positive pressure direction and negative ion cleaning to bring impurities and positively charged particles adhering to the surface of the cutting wire into the negative pressure environment at the bottom of the cleaning chamber 1011, thereby cleaning the surface of the cutting wire 200 and reducing the impact of the cutting wire 200 on the quality of materials.

[0049] At the same time, negative ions can also adsorb positively charged particles in the air, causing them to clump together and settle to the bottom of the cleaning chamber 1011, reducing the concentration of suspended particles in the air and further improving the cleanliness of the surface of the cutting line 200.

[0050] Furthermore, the cutting wire cleaning device provided in this application embodiment does not require shutting down the cutting device. It cleans the surface of the cutting wire 200 online in real time before the cutting wire 200 cuts the material, which significantly improves the method of relying on manual cleaning of the cutting wire 200, improves the cleaning effect and cleaning efficiency, and provides protection for the personal safety of the operators.

[0051] It should be noted that the cutting wire cleaning device provided in this application embodiment can also be equipped with ultrasonic cleaning, electrostatic cleaning, etc., to further improve the cleaning effect.

[0052] refer to Figure 3 and Figure 4 In this embodiment of the application, the cutting wire cleaning device further includes a filter mechanism 102.

[0053] The filtration unit 102 includes an inlet and an outlet.

[0054] The cleaning chamber 1011 also includes an air outlet 1013, which is connected to the inlet of the filter mechanism 102. The directional airflow that has been cleaned in the cleaning chamber 1011 flows into the filter mechanism 102 through the air outlet 1013. The filter mechanism 102 is used to remove impurities in the directional airflow to ensure the cleanliness of the airflow.

[0055] The outlet of the filter mechanism 102 is connected to the air inlet duct of the fan 103. The directional airflow filtered by the filter mechanism 102 will be circulated back to the fan 103 so that the fan 103 can continuously deliver airflow with preset air pressure and preset air volume to the cleaning chamber 1011 in real time.

[0056] By creating a closed environment and real-time filtration, a circulating clean airflow is formed, which improves cleaning performance, optimizes energy consumption, and reduces system energy consumption.

[0057] refer to Figures 5-7 In this embodiment of the application, the cleaning mechanism 101 includes a housing 1014.

[0058] The housing 1014 can be a rectangular housing, with the length direction of the rectangular housing parallel to the extension direction of the cutting line 200, so as to maximize the time that the cutting line 200 spends in the housing 1014 and improve the cleaning effect of the cutting line 200.

[0059] The housing 1014 is provided with a first horizontal plate 1018 and a second horizontal plate 1019 arranged at intervals along the vertical direction (z-axis shown in the figure). The first horizontal plate 1018, the second horizontal plate 1019 and the inner side wall of the housing 1014 together enclose the cleaning chamber 1011.

[0060] The first horizontal plate 1018 is provided with a plurality of arrayed air inlet holes 10181, and the second horizontal plate 1019 is provided with a plurality of arrayed air outlet holes 10191. The plurality of air inlet holes 10181 are all connected to the air inlet 1012, and the plurality of air outlet holes 10191 are all connected to the air outlet 1013.

[0061] The central axes of the multiple air inlet holes 10181 and the multiple air outlet holes 10191 are all parallel to the vertical direction (the z-axis shown in the figure), and the central axis of each air inlet hole 10181 corresponds to the central axis of an air outlet hole 10191.

[0062] The airflow delivered by the fan 103 is diverted to multiple air inlet holes 10181, enters the cleaning chamber 1011 through the multiple air inlet holes 10181, and flows out of the cleaning chamber 1011 through multiple air outlet holes 10191. Since the central axis of each air inlet hole 10181 corresponds to the central axis of an air outlet hole 10191, multiple directional airflows flowing in the vertical direction (z-axis shown in the figure) are formed in the cleaning chamber 1011. The distribution of these directional airflows can reduce cleaning blind spots and ensure cleaning effect. At the same time, the dispersed directional airflows can also avoid local stress concentration and prevent damage to the surface of the cutting line 200.

[0063] In this embodiment of the application, the diameter of the air inlet hole 10181 and the air outlet hole 10191 is 2.0mm. That is to say, the multiple air inlet holes 10181 and the multiple air outlet holes 10191 are all small holes, which can minimize the cleaning blind spots.

[0064] In this embodiment of the application, the depth of the air inlet hole 10181 and the air outlet hole 10191 is 15mm. This depth can ensure that the air inlet hole 10181 and the air outlet hole 10191 are aligned vertically and penetrate each other.

[0065] Continue to refer to Figures 5-7In this embodiment of the application, along the vertical direction (z-axis shown in the figure), the box body 1014 includes an upper cover plate 10141 and a lower bottom plate 10142. The upper cover plate 10141 is opposite to and spaced apart from the first horizontal plate 1018, and the lower bottom plate 10142 is opposite to and spaced apart from the second horizontal plate 1019.

[0066] The upper cover plate 10141 is provided with a plurality of first openings 10143 protruding away from the cleaning chamber 1011. The plurality of first openings 10143 are connected to the air inlet 1012 through a first pipe 1015. The plurality of first openings 10143 are distributed at equal intervals along the extension direction of the cutting line 200. The lower base plate 10142 is provided with a plurality of second openings 10144 protruding away from the cleaning chamber 1011. The plurality of second openings 10144 are connected to the air outlet 1013 through a second pipe 1016. The plurality of second openings 10144 are distributed at equal intervals along the extension direction of the cutting line 200.

[0067] The airflow delivered by the fan 103 enters the first pipe 1015 through the air inlet 1012 and is then diverted to multiple first pipe openings 10143. The airflow flows through the multiple first pipe openings 10143 into the flow channel between the upper cover plate 10141 and the first horizontal plate 1018, and is then diverted to multiple air inlet holes 10181 through the flow channel, thereby flowing into the cleaning chamber 1011.

[0068] Multiple directional airflows flowing vertically (z-axis as shown in the figure) within the cleaning chamber 1011 converge into the flow channel between the lower base plate 10142 and the second horizontal plate 1019 through multiple air outlet holes 10191. The airflow is then diverted to multiple second pipe openings 10144 through the flow channel, and finally flows out from the air outlet 1013.

[0069] The first port 10143 and the second port 10144, which are distributed at equal intervals along the extension direction of the cutting line 200, enable the airflow delivered by the fan 103 to be evenly distributed into multiple air inlet holes 10181, ensuring the uniformity of multiple directional airflows formed in the cleaning chamber 1011 and avoiding uneven cleaning effect on the surface of the cutting line 200 after cleaning.

[0070] In this embodiment of the application, the central axes of the plurality of first ports 10143 and the plurality of second ports 10144 are all parallel to the vertical direction (the z-axis shown in the figure), and the central axis of each first port 10143 corresponds to the central axis of a second port 10144.

[0071] Symmetrical and vertically arranged pipe openings can reduce airflow resistance, optimize energy consumption, and reduce system energy consumption.

[0072] refer to Figure 6and Figure 7 In this embodiment of the application, the inner surface of the upper cover plate 10141 is opposite to and spaced apart from the first horizontal plate 1018. The outer surface of the upper cover plate 10141 is provided with a plurality of negative ion generators 1017. The plurality of negative ion generators 1017 are distributed at equal intervals along the extension direction of the cutting line 200. The plurality of negative ion generators 1017 are used to release negative ions in the cleaning chamber 1011 to achieve uniform distribution of negative ions in the cleaning chamber 1011, avoid local concentrations that are too high or too low, and further optimize the cleaning effect.

[0073] Two negative ion generators 1017 can be installed between two adjacent first ports 10143; they can continuously output hundreds of millions of negative ions through the input of 12V DC voltage.

[0074] refer to Figure 8 It should be noted that the discharge needle 10171 of the negative ion generator 1017 passes through the upper cover plate 10141 and the first horizontal plate 1018 and extends into the cleaning chamber 1011, thereby releasing negative ions in the cleaning chamber 1011.

[0075] refer to Figure 9 and Figure 10 In this embodiment of the application, the filtration mechanism 102 includes a housing 1021 and a filter element 1022 disposed within the housing.

[0076] The housing 1021 includes a bottom surface 1024 and a removable top cover 1023 that are opposite each other in the vertical direction (z-axis shown in the figure). The removable top cover 1023 is provided with an inlet 10211, and the bottom surface 1024 is provided with an outlet 10212. Both the inlet 10211 and the outlet 10212 are pipe openings protruding from the outer wall of the housing 1021.

[0077] Along the vertical direction (z-axis shown in the figure), the upper surface of the filter element 1022 is opposite to and spaced from the removable top cover 1023, and the lower surface of the filter element 1022 is opposite to and spaced from the bottom surface 1024. The airflow mixed with pollutants flowing out from the air outlet 1013 flows into the flow channel between the filter element 1022 and the removable top cover 1023 through the inlet 10211, and then enters the filter element 1022 to complete filtration. The filtered clean airflow flows into the flow channel between the filter element 1022 and the bottom surface 1024, and then flows through the flow channel to the outlet 10212, and enters the fan 103 to complete recycling.

[0078] In this embodiment, the filtration mechanism 102 includes a high-efficiency filter with significant filtration effect.

[0079] In this embodiment, the air pressure of the directional airflow delivered by the fan 103 to the cleaning chamber 1011 is 30KPa-50KPa; the air volume of the directional airflow is 20m³. 3 / H, so that the cleaning chamber 1011 has a preset air pressure and preset air volume.

[0080] Continue to refer to Figure 1 and Figure 2 This application also provides a slicing machine, which includes the cutting wire cleaning device 100 described above, and also includes a cutting wire 200, a slicing device 300 and a wire wheel device 400.

[0081] The thread reel device 400 is used to guide and tension the cutting thread 200, forming the thread reel area B.

[0082] The thread reel device 400 includes a control unit 401, a drive wheel 402, a first auxiliary wheel 403, a second auxiliary wheel 404, and a third auxiliary wheel 405. The control unit 401 is used to control the rotation of the drive wheel 402. The cutting wire 200 is wound around the drive wheel 402. The first auxiliary wheel 403 is used to draw out the initial segment of the cutting wire 200 and guide it to the second auxiliary wheel 404 and the third auxiliary wheel 405.

[0083] The slicing device 300 is used to feed the material so that the material comes into contact with the cutting line 200 to form the cutting zone A.

[0084] The third auxiliary wheel 405 is located in the cutting area A and is used to guide the cutting line 200 to the cutting area A to ensure that the cutting line 200 is in contact with the material.

[0085] The cutting wire cleaning device 100 is installed in the reel area B and is located between the second auxiliary reel 404 and the third auxiliary reel 405. It is used to clean the cutting wire 200 before it comes into contact with the material.

[0086] The slicer provided in this application embodiment does not require shutting down the cutting device 300. It cleans the surface of the cutting line 200 online in real time before the cutting line 200 cuts the material, which significantly improves the method of relying on manual cleaning of the cutting line 200, improves the cleaning effect and cleaning efficiency, and provides protection for the personal safety of the operators.

[0087] In summary, this application provides a wire cleaning device and a slicing machine. The wire cleaning device includes a cleaning mechanism 101 and a fan 103. The cleaning mechanism 101 includes a cleaning chamber 1011 through which the wire 200 can pass. The extension direction of the wire 200 is perpendicular to the vertical direction (z-axis shown in the figure). Negative ions can be released in the cleaning chamber 1011. The negative ions actively adsorb positively charged particles in the air and adhering to the surface of the wire 200, causing them to settle to the bottom of the cleaning chamber 1011. The cleaning chamber 1011 includes an air inlet 1012, which is connected to the air supply duct of the fan 103, so that a directional airflow parallel to the vertical direction is formed in the cleaning chamber 1011. This directional airflow is used to clean the surface of the wire 200.

[0088] The cutting wire cleaning device provided in this application embodiment uses a dual approach of directional airflow in the positive pressure direction and negative ion cleaning to bring impurities and positively charged particles adhering to the surface of the cutting wire into the negative pressure environment at the bottom of the cleaning chamber 1011, thereby cleaning the surface of the cutting wire 200 and reducing the impact of the cutting wire 200 on the quality of materials.

[0089] At the same time, negative ions can also adsorb positively charged particles in the air, causing them to clump together and settle to the bottom of the cleaning chamber 1011, reducing the concentration of suspended particles in the air and further improving the cleanliness of the surface of the cutting line 200.

[0090] Furthermore, the cutting wire cleaning device provided in this application embodiment does not require shutting down the cutting device. It cleans the surface of the cutting wire 200 online in real time before the cutting wire 200 cuts the material, which significantly improves the method of relying on manual cleaning of the cutting wire 200, improves the cleaning effect and cleaning efficiency, and provides protection for the personal safety of the operators.
