Description

Technical Field

[0001] The present disclosure relates to the technical field of fluid control, and in particular to a liquid supply system and a slicer using the liquid supply system to provide cooling liquid. Background Art

[0002] A slicer is a device used to cut metal materials and semiconductor substrate materials. These materials include but are not limited to silicon, germanium, gallium arsenide, sapphire and other similar hard and brittle materials. Slicers play a vital role in the cutting process of solar cell glass panels, silicon wafers, ceramic wafers, sapphire substrates, silicon carbide substrates, etc.

[0003] During the cutting process, the slicer uses the high-speed moving diamond wire to contact the material to achieve precise cutting of the material. However, the high-speed friction between the diamond wire and the material will generate a lot of heat. This heat may not only damage the diamond wire and shorten its service life, but also affect the cutting quality, causing heat-affected zones or stress cracks in the workpiece. Therefore, in order to ensure the stability of the diamond wire and the quality of the workpiece, effective cooling treatment must be carried out through coolant.

[0004] Traditional slicer cooling systems usually involve a continuous supply of fresh coolant to maintain the temperature and cleanliness of the cutting area. These systems often rely on the consumption of a large amount of coolant, and the used coolant is usually directly discharged, which not only wastes resources, but also increases environmental pollution and production costs. In addition, frequent coolant changes will also cause production interruptions and affect efficiency.

[0005] Specifically, in the prior art, the use and treatment of coolant has at least the following problems:

[0006] Waste of resources: The chips and powder generated during the cutting process will contaminate the coolant, making it impossible to reuse the coolant, thus causing a waste of resources;

[0007] Environmental impact: The use and discharge of large amounts of coolant puts a burden on the environment, especially if the coolant contains hazardous substances, the discharge of which may violate environmental regulations;

[0008] Increased costs: Frequent purchase and replacement of coolant increases production costs, especially when the coolant price is high or the supply is unstable;

[0009] Inefficiency: Production needs to be stopped regularly to replace coolant, which reduces production efficiency and machine utilization.

[0010] Therefore, it is necessary to develop a new coolant supply system to improve cooling efficiency, reduce maintenance costs, reduce resource waste, and improve the overall performance and production efficiency of the slicer. Summary of the invention

[0011] A technical problem to be solved by the present disclosure is that the chips and powder generated during the cutting process of the slicer will contaminate the coolant, causing the coolant to be unable to be reused and to be directly discharged into the external environment.

[0012] To solve the above technical problems, an embodiment of the present disclosure provides a liquid supply system, which includes: a coolant supply barrel; a first pipeline, the input end of the first pipeline is connected to the coolant supply barrel, and the output end of the first pipeline is connected to the coolant nozzle; a waste liquid collection barrel, the waste liquid collection barrel is located below the spraying area of ​​the coolant nozzle to collect the waste coolant sprayed from the coolant nozzle and used; a second pipeline, the input end of the second pipeline is connected to the waste liquid collection barrel; a sedimentation tank, the sedimentation tank is connected to the output end of the second pipeline, and is used to receive and process the waste coolant; and a third pipeline, the input end of the third pipeline is connected to the sedimentation tank, and the output end of the third pipeline is connected to the coolant supply barrel, so as to return the waste coolant processed by the sedimentation tank to the coolant supply barrel.

[0014] In some embodiments, the liquid supply system includes a controller, which is configured to control the operation of the cleaning liquid supply pump and control the opening and closing of the three ports of the three-way valve.

[0015] In some embodiments, the liquid supply system further includes a fifth pipeline for replenishing the cooling liquid into the cooling liquid supply barrel, and / or the liquid supply system further includes a sixth pipeline for replenishing the cooling liquid supply barrel with reverse osmosis water.

[0016] In some embodiments, a metering pump is disposed on the fifth pipeline, and / or a metering pump is disposed on the sixth pipeline.

[0017] In some embodiments, a plurality of liquid level sensors spaced apart along the height direction are provided in the coolant supply barrel and the sedimentation tank, a liquid supply pump is provided on the third pipeline, and the liquid supply system includes a controller, which is configured to control the opening and closing of the liquid supply pump according to the liquid level information of the coolant supply barrel and the sedimentation tank monitored by the plurality of liquid level sensors.

[0018] In some embodiments, the liquid supply system includes an alarm electrically connected to a plurality of liquid level sensors, and the controller can control the opening and closing of the alarm according to the liquid level information of the coolant supply tank and the sedimentation tank monitored by the plurality of liquid level sensors.

This system not only reduces the number of times coolant is added from the outside, but also improves the cooling efficiency, reduces maintenance costs, and reduces resource waste, thereby using coolant more efficiently, economically and environmentally friendly during the slicer cutting process.

[0033] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0034] like Figure 1 As shown, the present disclosure provides a liquid supply system on the one hand, which includes: a coolant supply barrel 2; a first pipeline 11, the input end of the first pipeline 11 is connected to the coolant supply barrel 2, and the output end of the first pipeline 11 is connected to the coolant nozzle 7; a waste liquid collection barrel 8, the waste liquid collection barrel 8 is located below the spraying area of ​​the coolant nozzle 7 to collect the waste coolant sprayed from the coolant nozzle 7 and used; a second pipeline 12, the input end of the second pipeline 12 is connected to the waste liquid collection barrel 8; a sedimentation tank 3, the sedimentation tank 3 is connected to the output end of the second pipeline 12, and is used to receive and process the waste coolant; and a third pipeline 13, the input end of the third pipeline 13 is connected to the sedimentation tank 3, and the output end of the third pipeline 13 is connected to the coolant supply barrel 2, so as to return the waste coolant processed by the sedimentation tank 3 to the coolant supply barrel 2.

[0035] The first pipeline 11 is used to transport the coolant in the coolant supply barrel 2 to the coolant nozzle 7. There are many specific ways to set the first pipeline 11. For example, a coolant drain pipe is set at the bottom of the coolant supply barrel 2, and the coolant drain pipe is connected to the input end of the first pipeline 11. The input end of the first pipeline 11 is set to have a height greater than the height of the output end of the first pipeline 11 from the ground, so that the coolant in the coolant supply barrel 2 naturally flows to the output end of the first pipeline 11 under the action of gravity, and finally flows to the coolant nozzle 7 connected to the output end of the first pipeline 11; for another example, Figure 1 As shown, the input end of the first pipeline 11 can also directly extend along the upper opening of the coolant supply barrel 2 into the coolant supply barrel 2, and the coolant in the coolant supply barrel 2 can be drawn to the coolant nozzle 7 by the coolant supply pump 112 arranged on the first pipeline 11.

[0036] The waste liquid collection barrel 8 is used to temporarily store waste coolant, which mainly refers to waste coolant generated during the cutting process of the slicer. In this specific scenario, the spraying area of ​​the coolant nozzle 7 is the cutting area of ​​the slicer. Of course, this does not mean that the liquid supply system can only match the slicer cutting process. Other scenarios that require spraying coolant and collecting and processing waste coolant to form a coolant circulation can also be applied to the liquid supply system.

[0037] Exemplarily, the waste liquid collection process generated by the slicer during the cutting process and the related principles involved can be specifically expressed through the following steps: the first step is to spray coolant. When the slicer is cutting, the metal wire used for cutting contacts the material to be cut and cuts through high-speed movement and grinding. Simultaneously, coolant is sprayed into the cutting area through the coolant nozzle 7 to reduce the heat generated during the cutting process and prevent the metal wire and the cut material from overheating; the second step is to form waste coolant. After contacting the cut material, the coolant will mix with the debris generated by the cutting, thereby forming waste coolant; the third step is to discharge and collect the waste coolant. The waste coolant formed splashes to the lowest level of the cutting area and flows out through the waste liquid outlet set at the lowest level, and then flows directly into the waste liquid collection barrel 8 located below the waste liquid outlet under the action of gravity.

[0038] The second pipeline 12 is used to transport the waste coolant temporarily stored in the waste liquid collection barrel 8 to the sedimentation tank 3. In addition, the specific configuration of the second pipeline 12 and the third pipeline 13 is the same as that of the first pipeline 11, so it will not be repeated.

[0039] In some embodiments, the output end of the first pipeline 11 is connected to the first port of the three-way valve 111, the second port of the three-way valve 111 is connected to the coolant nozzle 7, the third port of the three-way valve 111 is connected to the first port of the fourth pipeline 14, the second port of the fourth pipeline 14 is connected to the cleaning liquid supply barrel 4, and a cleaning liquid supply pump 141 is provided on the fourth pipeline 14, and the cleaning liquid supply pump 141 is used to transport the cleaning liquid in the cleaning liquid supply barrel 4 to the coolant nozzle 7.

[0040] In fact, it is difficult for the sedimentation tank 3 to completely remove the dust and particles mixed in the waste coolant, which means that the coolant processed by the sedimentation tank 3 and returned to the coolant supply barrel 2 through the third pipeline 13 is only relatively pure, and still contains a small amount of dust and particles. With the continuous operation of the liquid supply system, the dust and particles in the coolant supply barrel 2 will continue to accumulate. When they accumulate to a certain extent, they are likely to partially or even completely block the coolant nozzle 7, thereby causing the coolant flow rate sprayed through the coolant nozzle 7 to become smaller or even unable to spray the coolant, and then the coolant nozzle 7 has to be disassembled and cleaned separately. Therefore, in order to effectively prevent the coolant nozzle 7 from being blocked by dust and particles, a fourth pipeline 14 is specifically set up, with the input end connected to the cleaning liquid supply barrel 4 and the output end connected to the coolant nozzle 7, and the liquid supply state is switched through the three-way valve 111. Specifically, when the coolant nozzle 7 is working, that is, when the coolant needs to be sprayed through the coolant nozzle 7, the first port and the second port of the three-way valve 111 are opened and the third port is closed. At this time, the coolant in the coolant supply barrel 2 flows along the first pipeline 11 to the coolant nozzle 7 and is sprayed out; when the coolant nozzle 7 stops the coolant spraying operation, the first port of the three-way valve 111 is closed and the second port and the third port are opened, and then the cleaning liquid supply pump 141 is started. The cleaning liquid supply pump 141 will transport the cleaning liquid in the cleaning liquid supply barrel 4 to the coolant nozzle 7, thereby completing its cleaning without disassembling the coolant nozzle 7.

[0041] In some embodiments, the liquid supply system includes a controller, which is configured to control the operation of the cleaning liquid supply pump 141 and control the opening and closing of the three ports of the three-way valve 111 .

[0042] Specifically, the controller can indirectly control the cleaning frequency by controlling the opening and closing of the three ports of the three-way valve 111. For example, the coolant nozzle 7 is cleaned every time it stops working. In this case, the controller needs to be set to open the third port and the cleaning liquid supply pump 141 in sequence after closing the first port of the three-way valve 111 each time; for another example, the coolant nozzle 7 is cleaned every two times it stops working. In this case, the controller can be set to open the third port and the cleaning liquid supply pump 141 in sequence only after the first port of the three-way valve 111 has undergone a pre-process of closing-opening-closing twice; and so on. It is worth noting that the controller can also control the opening time and closing time of the cleaning liquid supply pump 141. When the liquid supply system acts on the slicer, by presetting a time delay, it can be ensured that the slicer has completely stopped before the cleaning liquid supply pump 141 is started, and the liquid supply system is ready for cleaning.

[0043] In some embodiments, the liquid supply system further includes a fifth pipeline 15 for replenishing coolant into the coolant supply barrel 2, and / or the liquid supply system further includes a sixth pipeline 16 for replenishing reverse osmosis water into the coolant supply barrel 2. Specifically, replenishing coolant and / or reverse osmosis water into the coolant supply barrel 2 helps to reduce the content of dust and particulate matter per unit volume, thereby reducing the frequency of replacing the coolant, and effectively avoiding the first pipeline 11 and the coolant nozzle 7 from being blocked due to excessive dust and particulate matter in the liquid circulating per unit time.

[0044] In some embodiments, a metering pump 5 is provided on the fifth pipeline 15, and / or a metering pump 5 is provided on the sixth pipeline 16. Specifically, the metering pumps 5 on the fifth pipeline 15 and the sixth pipeline 16 are relatively independently provided, and can quantitatively replenish the coolant and the reverse osmosis water respectively, so as to achieve precise control of the flow rate and replenishment ratio of the liquid. Further, when the metering pumps 5 on the fifth pipeline 15 and the sixth pipeline 16 work together, the ratio of the reverse osmosis water and the coolant can be precisely controlled, so as to maintain the optimal performance and stability of the coolant in the coolant supply barrel 2.

[0045] In some embodiments, a plurality of liquid level sensors 6 spaced apart along the height direction are provided in the coolant supply barrel 2 and the sedimentation tank 3, a liquid supply pump 131 is provided on the third pipeline 13, and the liquid supply system includes a controller, which is configured to control the opening and closing of the liquid supply pump 131 according to the liquid level information of the coolant supply barrel 2 and the sedimentation tank 3 monitored by the plurality of liquid level sensors 6.

[0046] Specifically, the liquid level sensor 6 in the coolant supply barrel 2 is provided with at least a first liquid level sensor 61 and a second liquid level sensor 62, and the first liquid level sensor 61 and the second liquid level sensor 62 respectively monitor the preset maximum liquid level and minimum liquid level of the coolant supply barrel 2; the liquid level sensor 6 in the sedimentation tank 3 is similarly provided with at least a third liquid level sensor 63 and a fourth liquid level sensor 64, and the third liquid level sensor 63 and the fourth liquid level sensor 64 respectively monitor the preset maximum liquid level and minimum liquid level of the sedimentation tank 3. When the coolant in the coolant supply barrel 2 exceeds the preset maximum liquid level, the first liquid level sensor 61 will transmit a signal to the controller, and the controller will further send a shutdown signal to the liquid supply pump 131, and the liquid supply pump 131 will stop running. At this time, the coolant treated by the sedimentation tank 3 will not flow back to the coolant supply barrel 2 through the third pipeline 13; when the coolant in the coolant supply barrel 2 is lower than the preset minimum liquid level, the second liquid level sensor 62 will transmit a signal to the controller, and the controller will further send a start signal to the liquid supply pump 131, and the liquid supply pump 131 will start running. At this time, the coolant treated by the sedimentation tank 3 is replenished to the coolant supply barrel 2 through the third pipeline 13 under the action of the liquid supply pump 131. Furthermore, the controller can also control the metering pump 5. When the liquid levels of the coolant supply barrel 2 and the sedimentation tank 3 are too low, the second liquid level sensor 62 and the fourth liquid level sensor 64 will simultaneously transmit signals to the controller. At this time, the controller will not send a control signal to the liquid supply pump 131, but will send a control signal to the metering pump 5 to quantitatively add coolant and / or reverse osmosis water to the coolant supply barrel 2. In addition, a liquid level sensor 6 can also be set in the cleaning liquid supply barrel 4 to monitor the liquid level information of the cleaning liquid, so as to detect and replenish the cleaning liquid in time.

[0047] In some embodiments, the liquid supply system includes an alarm electrically connected to the plurality of liquid level sensors 6 , and the controller can control the opening and closing of the alarm according to the liquid level information of the coolant supply barrel 2 and the sedimentation tank 3 monitored by the plurality of liquid level sensors 6 .

[0048] The main purpose of setting up an alarm is to provide additional security and information feedback, which can be specifically explained from the following aspects: First, remote notification. The alarm can send alarm information to the remote control center or relevant personnel to achieve timely response off-site; second, enhanced safety. The existence of the alarm improves the safety of the entire liquid supply system because it can provide backup warnings when the controller fails to respond effectively; third, record events. The alarm can record the time and duration of the alarm, providing data support for accident investigation and subsequent analysis, such as recording how many times the sedimentation tank 3 is below the minimum liquid level within a certain period of time, thereby providing operators with useful information such as whether it is necessary to improve the processing efficiency of the sedimentation tank 3.

[0049] In some embodiments, a one-way valve 121 is provided on the second pipeline 12, and the one-way valve 121 is used to allow the waste coolant to flow into the sedimentation tank 3 in one direction. Specifically, a one-way valve 121 can also be provided on other pipelines as appropriate, such as the fourth pipeline 14, and the one-way delivery of the cleaning liquid can ensure that the cleaning liquid in the cleaning liquid supply barrel 4 is not contaminated.

[0050] In some embodiments, the sedimentation tank 3 includes multiple sedimentation tanks, and isolation walls are arranged between the multiple sedimentation tanks. A filter screen is arranged at the upper end of the isolation wall.

[0051] Specifically, Figure 1 As shown, the sedimentation tank 3 is divided into three levels, including a primary sedimentation tank 31, a secondary sedimentation tank 32, and a tertiary sedimentation tank 33. Among them, a first isolation wall 34 and a first filter 341 are arranged between the primary sedimentation tank 31 and the secondary sedimentation tank 32; a second isolation wall 35 and a second filter 351 are arranged between the secondary sedimentation tank 32 and the tertiary sedimentation tank 33. The aperture of the second filter 351 is smaller than the aperture of the first filter 341 to achieve multi-stage filtration. Accordingly, the height of the second isolation wall 35 is set to be greater than the height of the first isolation wall 34. The isolation wall with increasing height can provide a longer residence time for solid particles, which is conducive to the sedimentation of lighter or finer particles entering the secondary sedimentation tank 32, and avoids part of the coolant in the secondary sedimentation tank 32 from flowing into the tertiary sedimentation tank 33 without sufficient precipitation. Of course, according to the needs of actual working conditions, it can also be set as four or more levels of sedimentation tanks.

[0052] Another aspect of the present disclosure provides a slicer that provides cooling liquid through a liquid supply system during a cutting process.

[0053] Combination Figure 1 The preferred embodiment shown specifically illustrates the complete working process of the slicer and the liquid supply system used therein:

[0054] Cutting process: During the slicer cutting operation, the coolant nozzle 7 sprays coolant to the cutting area synchronously. The coolant in the coolant nozzle 7 is continuously supplied through the coolant supply barrel 2. When the second liquid level sensor 62 in the coolant supply barrel 2 detects that the coolant in the coolant supply barrel 2 is lower than the preset minimum liquid level, it will transmit a signal to the controller, and the controller will further send a start signal to the liquid supply pump 131, and the liquid supply pump 131 will start to run. The liquid supply pump 131 in the working state will extract the upper clarified liquid of the tertiary sedimentation tank 33 (i.e., the relatively pure coolant after being treated in the multi-stage sedimentation tank) to the coolant supply barrel 2 through the third pipeline 13 to replenish the coolant that can be directly used by the coolant nozzle 7. When the coolant in the coolant supply barrel 2 and the treated coolant in the tertiary sedimentation tank 33 are both lower than the preset minimum liquid level, the controller will control the metering pump 5 to start after receiving the signals transmitted simultaneously by the second liquid level sensor 62 and the fourth liquid level sensor 64, so as to quantitatively replenish the coolant and / or reverse osmosis water to the coolant supply barrel 2.

[0055] Waste liquid recycling process: The process of recycling and processing waste coolant by the liquid supply system is carried out simultaneously with the cutting process. After the coolant comes into contact with the cut material, it will mix with the debris generated by the cutting to form waste coolant and scatter to the lowest level of the cutting area. Furthermore, the waste coolant will flow out along the waste liquid outlet set at the lowest level of the cutting area, and then directly flow into the waste liquid collection barrel 8 located below the waste liquid outlet under the action of gravity. The waste coolant in the waste liquid collection barrel 8 will be transported unidirectionally to the primary sedimentation tank 31, and then processed in the primary sedimentation tank 31, the secondary sedimentation tank 32 and the tertiary sedimentation tank 33 in turn. The treated coolant, especially the part of the coolant at a higher liquid level in the tertiary sedimentation tank 33, can be directly reused. According to the instructions of the controller, it will flow back to the coolant supply barrel 2 along the third pipeline 13 under the action of the liquid supply pump 131 when necessary.

[0056] Cleaning process: When the slicer stops abnormally or after a certain number of cuts, the coolant nozzle 7 and the liquid inlet pipeline of the slicer need to be cleaned. First, the first port of the three-way valve 111 is closed by the controller to stop the delivery of coolant to the coolant nozzle 7; then, the third port of the three-way valve 111 is opened by the controller; finally, after determining that the slicer has completely stopped, the cleaning liquid supply pump 141 is started by the controller to deliver the cleaning liquid in the cleaning liquid supply barrel 4 to the third port of the three-way valve 111 along the fourth pipeline 14, and further, the cleaning liquid is continued to be delivered to the liquid inlet pipeline of the slicer along the second port of the three-way valve 111 until the cleaning liquid is finally delivered to the coolant nozzle 7 and sprayed out through the coolant nozzle 7, so as to achieve a thorough cleaning of the liquid inlet pipeline of the slicer and the coolant nozzle 7.
