Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of wire cutting, and in particular relates to a cutting liquid supply device and a cutting liquid circulation system. Background Art
[0002] Wire cutting machine is a kind of equipment that uses diamond wire to cut hard and brittle materials. Wire cutting machine generally includes main roller, wire net and cutting fluid circulation system. The cutting fluid circulation system is used to spray cooling on wire net or workpiece to prevent overheating during cutting process.
[0003] The existing cutting fluid circulation system generally includes a cutting fluid supply device, a filter tank, a heat exchanger, a three-way assembly and a spray assembly. The spray assembly sprays at the cutting area, and the sprayed cutting fluid can flow back to the cutting fluid supply device. The cutting fluid supply device can be recycled and then pumped to the filter tube by the pumping assembly for filtration. The filtered cutting fluid enters the heat exchanger for heat exchange, then enters the three-way assembly, and finally returns to the spray assembly for continued spraying, thus completing the cycle. However, with the trend of thinning and fine-line slicing, the number of cycles in the cutting fluid increases, and the concentration of silicon powder is also getting higher and higher, resulting in the need to replenish more cutting fluid in the cycle. Excessive replenishment of cutting fluid is likely to cause waste of cutting fluid, while too little replenishment of cutting fluid is likely to cause an increase in silicon powder concentration, affecting the cutting quality. Therefore, it is difficult to achieve a reasonable allocation of the amount of cutting fluid replenished and the concentration of silicon powder in the cutting fluid.

[0037] See also Figure 1 and Figure 2The cutting liquid supply device of the present application includes a container 100 and a silicon powder concentration acquisition module 400. Among them, the container 100 includes a first tank body 110 and a second tank body 120. The first tank body 110 is provided with a liquid inlet 111 and a first liquid discharge component 112. The liquid inlet 111 is used to receive the first liquid. The first liquid discharge component 112 can control the first tank body 110 to discharge the first liquid; the second tank body 120 is arranged on one side of the first tank body 110, and an overflow channel 130 is provided between the second tank body 120 and the first tank body 110. The overflow channel 130 can allow the first liquid of the first tank body 110 to overflow to the second tank body 120. The second tank body 120 is also provided with a liquid replenishment component 200. and a liquid delivery component 300, the liquid replenishment component 200 can replenish the second liquid to the second tank body 120, the liquid delivery component 300 leads to the outside of the container 100 to form a liquid delivery pipeline S, so as to deliver the first liquid and / or the second liquid of the second tank body 120 into the liquid delivery pipeline S; the silicon powder concentration acquisition module 400 is arranged in the second tank body 120 and / or on the liquid delivery pipeline S to obtain the silicon powder concentration information of the liquid, and the silicon powder concentration acquisition module 400 is communicated with the first liquid discharge component 112 and / or the liquid replenishment component 200, as Fig. 9 Based on the silicon powder concentration information, the first draining component 112 performs a draining operation and / or the replenishing component 200 performs a replenishing operation.
[0038] It can be understood that by dividing the container 100 into a first tank body 110 and a second tank body 120, the liquid inlet 111 of the first tank body 110 is used to receive the first liquid, and the first liquid is at least a cutting liquid used once in the cutting area. Therefore, the first liquid contains more silicon powder, and the silicon powder can fall and settle in the first tank body 110, and the cleaner upper layer of the first liquid can enter the second tank body 120 through the overflow channel 130. The silicon powder concentration of the first liquid entering the second tank body 120 is low, and can be pumped to the liquid path outside the container 100 by the liquid delivery component 300 of the second tank body 120 until it is pumped to the cutting area, and then the cutting liquid used twice or more is recovered by the liquid inlet 111. Exemplarily, the liquid delivery component 300 can be a water pump.In addition, since it is difficult to meet the liquid supply demand in the second tank body 120 with only the overflowing first liquid, the present application also provides a liquid replenishing component 200 to replenish the second tank body 120 with a relatively clean second liquid. The first liquid and the second liquid are mixed and transported by the liquid delivery component 300, that is, the liquid supply demand is met. It should be noted that the amount of liquid replenishment has a certain correlation with the cutting quality. When the amount of the second liquid replenished in the second tank body 120 is small, it means that the second tank body 120 needs to receive more first liquid overflowing from the first tank body 110, and the silicon powder concentration of the first liquid is relatively high. For higher silicon powder concentrations, after multiple cycles, even in the overflow layer, the silicon powder concentration of the final pumped liquid will still increase after mixing, which can easily affect the cutting quality of the workpiece. If the amount of the second liquid added to the second tank body 120 is large, it means a large amount of waste of cutting liquid. Based on this, the present application adds a silicon powder concentration acquisition module 400, through which the silicon powder concentration in the second tank body 120 is obtained, and a standard concentration is set for the silicon powder concentration in the second tank body 120. When the actual silicon powder concentration detected is greater than or equal to the set standard concentration, it is necessary to increase the amount of liquid replenishment to obtain the silicon powder concentration in the second tank body 120. Lowering the actual silicon powder concentration in the second tank body 120 also means that the actual silicon powder concentration in the first tank body 110 is higher. The first liquid discharge component 112 can optionally discharge part or all of the first liquid in the first tank body 110 to reduce the silicon powder concentration of the first liquid overflowing from the overflow channel 130 next time. When the detected actual silicon powder concentration is less than the set standard concentration, it is not necessary to replenish the liquid, nor is it necessary to perform a liquid discharge operation on the first liquid discharge component 112 in the first tank body 110, and it is sufficient to wait for overflow. The first liquid discharge component 112 includes a first liquid discharge pipe and The first proportional valve can effectively control the discharge amount of the first liquid discharged from the first drainage pipe. The refilling assembly 200 may include a refilling pipe and a second proportional valve. The refilling pipe is connected to an external cutting liquid source, and the second proportional valve controls the refilling amount of the refilling pipe; wherein, a signal receiver is provided on the proportional valve and the refilling pipe, and the silicon powder concentration acquisition module 400 is connected to the proportional valve and / or the refilling pipe through a controller. The controller is responsible for receiving and processing information from the silicon powder concentration acquisition module 400, and controlling the first drainage assembly and / or the refilling assembly to perform corresponding operations. It should be noted that when the silicon powder concentration acquisition module 400 is on the liquid delivery pipeline S of the liquid delivery assembly 300, obtaining the liquid silicon powder concentration of the pipeline is equivalent to obtaining the liquid silicon powder concentration in the second tank 120. To sum up, the setting of the first tank body 110 is equivalent to adding a more continuous filtering structure, which filters a large amount of silicon powder and can effectively increase the circulation times of the first liquid; the setting of the silicon powder concentration acquisition module 400 provides a silicon powder concentration monitoring function for the entire cutting liquid supply device, and can cooperate with the liquid replenishing component 200 to more flexibly adjust the silicon powder concentration of the liquid in the second tank body 120, thereby saving cutting fluid while preventing the cutting quality from being affected.
[0039] See also Figure 1 In some embodiments, the first tank body 110 of the present application is at least partially transparent, and a visual inspection unit 700 is provided on the outside of the first tank body 110. The visual inspection unit 700 captures an image of the first liquid in the first tank body 110 to detect and estimate the amount of silicon powder deposited in the first liquid. Based on the amount of silicon powder deposited, the first liquid discharge component 112 performs a corresponding liquid discharge operation. It can be understood that the visual inspection unit 700 is disposed on the outside of the first tank body 110 to avoid being damaged by the friction of the silicon powder in the first tank body 110. Due to the deposition of silicon powder in the first tank body 110, the distribution of silicon powder between liquid layers is relatively different. Therefore, by setting the visual inspection unit 700 to capture an image from the transparent part of the outside of the first tank body 110, the amount of silicon powder deposited is estimated and determined according to the color difference information of the image, so as to control the first liquid discharge component 112 to perform corresponding operations, such as level control of the liquid discharge amount and liquid discharge speed.
[0040] Continue to refer to Figure 1 In some embodiments, a second drainage component 121 is provided on the second tank body 120, and the second drainage component includes a second proportional valve or a pinch valve, and a signal receiver. The signal receiver of the second drainage component is connected to the silicon powder concentration module through a controller. The controller receives the silicon powder concentration information of the silicon powder concentration module, and based on the silicon powder concentration information, the controller controls the second drainage component 121 to perform the corresponding drainage operation. It can be understood that when the silicon powder concentration information obtained exceeds a certain value, and the rehydration component 200 cannot replenish the liquid in time to reduce the silicon powder concentration in the second tank body 120, such as when the liquid level of the second tank body 120 exceeds a certain value, the second drainage component 121 will start the drainage, thereby providing sufficient rehydration space for the rehydration component 200 so that the rehydration component 200 can replenish the liquid normally, thereby reducing the liquid silicon powder concentration in the second tank body 120. In some embodiments, the second drainage component 121 can use a pinch valve instead of the second proportional valve.
[0041] See also Figure 2 In some embodiments, a first filter assembly 113 is provided below the liquid inlet 111, and the first filter assembly 113 filters the first liquid. It is understandable that before the first liquid enters the first tank body 110, it needs to be pre-screened by the first filter assembly 113, and silicon powder or other larger particles with larger particles are placed on the first filter assembly 113, and only smaller silicon powder particles can enter the first tank body 110 through the first filter assembly 113. Exemplarily, the first filter assembly includes a filter screen (not shown in the figure), and the filter screen is plugged into the container 100.
[0042] join Figure 3In the cutting liquid supply device of the present application, an overflow assembly 140 is provided between the first tank body 110 and the second tank body 120. The overflow assembly 140 is movable to adjust the overflow amount of the overflow channel 130. The overflow assembly 140 includes a signal receiver, which is in communication connection with an external controller and a silicon powder concentration acquisition module 400. The controller receives silicon powder concentration information from the silicon powder concentration acquisition module 400 and sends corresponding execution information to the signal receiver of the overflow assembly 140 to control the overflow assembly 140 to adjust the overflow amount of the overflow channel 130. It can be understood that, when the silicon powder concentration acquisition module 400 acquires a lower silicon powder concentration, in order to reduce the waste of cutting liquid, the liquid replenishing component 200 will not replenish or only replenish a small amount of the second liquid, and most of the cutting liquid supply pressure is given to the first liquid overflowing from the first tank body 110. In the normal overflow state, the overflow amount of the first liquid is small and it is difficult to stably supply a large flow. Based on this, the present application sets an overflow component 140 between the first tank body 110 and the second tank body 120 to adjust the overflow amount of the overflow channel 130 according to the liquid silicon powder concentration information in the second tank body 120. That is, when the liquid silicon powder concentration in the second tank body 120 is low, the overflow component 140 increases the overflow amount of the overflow channel 130, and when the liquid silicon powder concentration in the second tank body 120 is high, the overflow component 140 reduces the overflow amount of the overflow channel 130 and can even close the overflow channel 130 to prevent overflow.
[0043] Please refer to Figure 2 and Figure 3In some embodiments, a liquid level detection module 500 is provided in the second tank body 120 of the present application, and the liquid level detection module 500 is used to detect and obtain the liquid level information in the second tank body 120. The liquid level detection module is communicated with the fluid replenishment component and / or the overflow component through a controller. Based on the liquid level information sent by the liquid level detection module 500 to the controller, the fluid replenishment component 200 performs a corresponding fluid replenishment operation, and / or the overflow component 140 is activated to adjust the overflow amount of the overflow channel 130. It is understandable that the supply of cutting fluid needs to be continuous and stable, and this continuity and stability is based on the sufficient storage capacity of liquid in the second tank body 120, that is, the minimum liquid level height and the maximum liquid level height need to be set in the second tank body 120. When the acquired liquid level information indicates that the actual liquid level height in the second tank body 120 is lower than the set minimum liquid level height, it indicates that the liquid delivery component 300 is difficult to maintain a stable supply of cutting fluid. Therefore, the fluid replenishment component 200 needs to increase the fluid replenishment volume / increase the fluid replenishment speed in time, or the overflow component 140 is activated to increase the overflow volume of the overflow channel 130, thereby ensuring that the liquid delivery component 300 can stably supply cutting fluid. When the acquired liquid level information indicates that the actual liquid level height in the second tank body 120 is higher than the set maximum liquid level height, it indicates that the second tank body 120 is about to be full or the liquid in the second tank body 120 is about to overflow to the first tank body 110. At this time, the fluid replenishment component 200 needs to reduce the fluid replenishment amount / reduce the fluid replenishment speed / stop the fluid replenishment in time, or the overflow component 140 is activated to reduce the overflow amount of the overflow channel 130, or even close the overflow channel 130 to provide a stable liquid supply environment.
[0044] See also Figure 3-Figure 5The overflow assembly 140 of the present application includes a first barrier 141, a second barrier 142, a signal receiver (not shown in the figure) and a driving unit 143. The first barrier 141 is arranged between the first trough body 110 and the second trough body 120, and the second barrier 142 is movably arranged relative to the first barrier 141. The signal receiver is communicatively connected with a controller and a silicon powder concentration acquisition module 400. Based on the silicon powder concentration information, the controller sends a command to the signal receiver to control the driving unit 143 to drive the second barrier 142 to movably adjust its position relative to the first barrier 141. Exemplarily, in some embodiments, the first barrier 141 is vertically placed in the container 100 to divide the container 100 into the first tank body 110 and the second tank body 120. The first barrier 141 blocks most of the first liquid from entering the second tank body 120. The driving unit 143 drives the second barrier 142 to be rotatably connected / slidably connected to the first barrier 141. The second barrier 142 rotates / slides to change the minimum height of the overflow channel 130 or the overflow area of the overflow channel 130, thereby achieving the control of the overflow amount. In some embodiments, the driving unit 143 drives the second barrier 142 to be set on the first barrier 141 in a telescopic manner, which can also change the minimum height or overflow area of the overflow channel 130. In some embodiments, both the first barrier 141 and the second barrier 142 can be movable, and the joint movement of the two can also adjust the overflow amount.
[0045] See also Figure 6In some embodiments, a stirring assembly 600 is provided in the second tank body 120, and the stirring assembly 600 acts in the second tank body 120. Based on the silicon powder concentration information, the stirring assembly 600 performs a corresponding stirring operation. It can be understood that since the first liquid overflowing from the first tank body 110 to the second tank body 120 has a higher silicon powder concentration than the second liquid replenished by the liquid replenishing assembly 200, after the two liquids are mixed in the second tank body 120, the silicon powder concentration of each layer of the liquid is not uniform. When the liquid delivery assembly 300 delivers the liquid, it delivers it in the order of the liquid layers, and does not homogenize the liquid, which easily causes the silicon powder concentration of part of the liquid delivered to the cutting area to not meet the cutting requirements, thereby affecting the cutting quality. Therefore, in order to avoid affecting the cutting quality, the stirring assembly 600 is provided to homogenize the liquid in the second tank body 120. In particular, when the obtained silicon powder concentration information indicates that the silicon powder concentration is high, the power of the stirring component 600 is configured to be high power, when the obtained silicon powder concentration information indicates that the silicon powder concentration is normal, the power of the stirring component 600 is configured to be low power, and when the obtained silicon powder concentration information indicates that the silicon powder concentration is low, the power of the stirring component 600 is configured to be ultra-low power or the stirring operation is turned off.

[0047] join Figure 8In the cutting liquid circulation system of the present application, there is at least one silicon powder concentration acquisition module 400 between the cutting liquid supply device, the second filter component 800, the heat exchange component 900, the three-way component 1000 and the spray component 1100. It can be understood that at least one silicon powder concentration acquisition module 400 for monitoring the silicon powder concentration is required in the liquid path between each device, module or component, so as to ensure that the cutting liquid entering the cutting area meets the concentration requirements. Preferably, the silicon powder concentration acquisition module 400 is arranged on the three-way component 1000, so as to facilitate the circulation of the cutting liquid according to the silicon powder concentration information.
[0048] Working principle: Before cutting, the liquid replenishing component 200 supplies a clean second liquid into the second tank body 120. When the liquid level detection module 500 detects that the liquid level in the second tank body 120 is higher than the set minimum liquid level height, the liquid delivery component 300 can be turned on to deliver the liquid. The liquid delivery component 300 delivers the liquid in the second tank body 120 into the second filter component 800, and then the second filter component 800 delivers the liquid into the heat exchange component 900 for heat exchange. The liquid after heat exchange is then delivered to the three-way component 1000, and the three-way component 1000 passes the liquid into the spray component 1100. The spray component 1100 sprays the liquid to the cutting area. The liquid used in the cutting area is converted into the first liquid. The first liquid enters from the feed port of the cutting liquid supply device below, and is initially filtered through the first filter component 113 into the first tank body 110 to screen out large particles of silicon powder. The upper layer of the first liquid in the first tank body 110 is a relatively clean liquid, and the lower layer is a small silicon powder deposition layer. The upper layer of the first liquid enters the second tank body 120 through the overflow channel 130, and is stirred by the stirring component 600 in the second tank body 120, so that the first liquid is mixed with the second liquid, and the silicon powder concentration acquisition module 400 obtains the silicon powder concentration of the second tank body 120. When the silicon powder concentration is high, the overflow component 140 is activated to reduce the overflow of the overflow channel 130, and increase the replenishment amount of the liquid replenishment component 200, and increase the stirring power of the stirring component 600, so as to quickly reduce the silicon powder concentration of the liquid in the second cavity. On the contrary, the overflow component 140 is activated to increase the overflow of the overflow channel 130, and reduce the replenishment amount of the liquid replenishment component 200, and reduce the stirring power of the stirring component 600, so as to prevent the waste of replenishment; finally, the liquid delivery component 300 delivers the mixed liquid to the second filter component 800, thereby entering the second cycle. Finally, after the entire workpiece is cut, the cutting fluid in the first trough 110 is drained through the first drainage component 112, and the cutting fluid in the second trough 120 is drained through the second drainage component 121, waiting for the next workpiece to be cut, and then the fluid replenishing component 200 is used again to replenish the fluid.
[0049] Beneficial effect: By dividing the container 100 into a first tank body 110 and a second tank body 120, it is prevented that the silicon powder in the same container 100 increases significantly with the increase of the number of cycles. The first tank body 110 can filter most of the silicon powder in the first liquid, so that the cutting liquid overflowing to the second tank body 120 is relatively clean, and then the relatively clean cutting liquid in the second tank body 120 is supplied to the outside of the container 100 for use by the liquid delivery component 300, thereby ensuring that the cutting quality is not affected and the number of cycles of the cutting liquid can be effectively increased; by setting a silicon powder concentration acquisition module 400, a silicon powder concentration monitoring function is provided for the entire cutting liquid supply device, which can cooperate with the liquid replenishment component 200 to more flexibly adjust the silicon powder concentration of the liquid in the second tank body 120, or discharge the liquid in the first tank body 110 in time, thereby saving liquid replenishment and Prevent the cutting quality of the workpiece from being affected; by setting an overflow component 140 between the first trough body 110 and the second trough body 120, the overflow amount of the overflow channel 130 can be flexibly adjusted in conjunction with the silicon powder concentration information, thereby controlling the refill component 200 to replenish a smaller and appropriate amount of refill, and a better balance ratio can be achieved between the overflow amount and the refill amount, ultimately improving the utilization rate of the cutting fluid; by setting a liquid level detection module 500 to detect the liquid level in the second trough body 120, the overflow component 140 and the refill component 200 can be coordinated to perform corresponding operations to adjust the liquid level in the second trough body 120, so that it is always in a healthier liquid level range, providing a more stable liquid supply environment for the liquid delivery component 300; by setting a stirring component 600, based on the silicon powder concentration information, more effective stirring power is provided, which is more energy-saving and environmentally friendly.
