Description

Technical Field

[0001] This application relates to the field of machining, specifically to a cutting fluid cleaning and replacement machine. Background Technology

[0002] In machining, cutting fluid plays multiple roles, including cooling, lubrication, rust prevention, and corrosion prevention. The quality of the cutting fluid directly affects machining efficiency, workpiece quality, and tool life. After a certain period of use, cutting fluid becomes contaminated, with suspended contaminants such as solid impurities appearing in the fluid, and sludge and metal shavings accumulating in the oil tank. All of these factors contribute to a decline in the performance of the cutting fluid. Therefore, the cutting fluid needs to be changed regularly to ensure the quality of the machined products. Currently, when changing the cutting fluid, on-site personnel typically use a pump to remove the contaminated cutting fluid, manually clean the sludge and metal shavings from the bottom of the oil tank, and then add new cutting fluid. This entire process is time-consuming, labor-intensive, and costly. Summary of the Invention

[0038] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0043] In machining, cutting fluid plays multiple roles, including cooling, lubrication, rust prevention, and corrosion prevention. The quality of the cutting fluid directly affects machining efficiency, workpiece quality, and tool life. After a certain period of use, cutting fluid becomes contaminated, with suspended contaminants such as solid impurities appearing in the fluid, and sludge and metal shavings accumulating in the oil tank. All of these factors contribute to a decline in the performance of the cutting fluid. Therefore, the cutting fluid needs to be replaced regularly to ensure the quality of the machined products. Currently, when replacing the cutting fluid, on-site personnel typically use a pump to remove the contaminated cutting fluid, manually clean the sludge and metal shavings from the bottom of the oil tank, and then add new cutting fluid. This process is time-consuming, labor-intensive, and costly. To address this problem, this application provides a cutting fluid cleaning and replacement machine (such as...). Figures 1 to 3 (As shown).

[0044] Please see Figures 1 to 4The cutting fluid cleaning and replacement machine 100 provided in this application includes a machine body 10, a moving component 20, a positioning unit 30, a fluid replacement component 40, an image acquisition unit 50, and a cleaning component 60. The moving component 20 is disposed on the machine body 10 and is used to move the machine body 10. The positioning unit 30 is disposed on the machine body 10 and is used to position the machine body 10 to the target machine 300 where the cutting fluid needs to be replaced. The fluid replacement component 40 is disposed on the machine body 10 and is used to extract cutting fluid from the oil tank 310 of the target machine 300 and to replenish the oil tank 310 with cutting fluid. The image acquisition unit 50 is disposed on the machine body 10 and is used to acquire a first image containing the oil tank 310 before the fluid replacement component 40 replenishes the oil tank 310 with cutting fluid. The first image is used to identify the degree of dirtiness in the oil tank 310. The cleaning component 60 is disposed on the machine body 10 and is used to clean the oil tank 310. Before the fluid replacement component 40 replenishes the cutting fluid to the oil tank 310, if the degree of dirtiness of the oil tank 310 reaches a preset threshold, the cleaning component 60 cleans the oil tank 310.

[0045] Specifically, the cutting fluid cleaning and replacement machine 100 is a device used to clean the oil tank of a machine tool, replace the cutting fluid in the oil tank, and remove slag. The cutting fluid cleaning and replacement machine 100 can be applied to various types of machine tools, including but not limited to lathes for turning, milling machines for milling, and drilling machines for drilling. The oil tank is a key structure in machining tools for storing and circulating cutting fluid. Cutting fluid is an important auxiliary liquid used for cooling, lubrication, rust prevention, and corrosion prevention in machining processes. Cutting fluid is widely used in turning, milling, drilling, and grinding processes. Cutting fluid can significantly improve the machining efficiency, the surface quality of the workpiece, and the life of the cutting tools. Depending on its composition and form, cutting fluid can be, but is not limited to, water-based or oil-based cutting fluids. Water-based cutting fluids offer better cooling performance. Oil-based cutting fluids offer better lubrication performance.

[0046] The body 10 is the main body of the cutting fluid cleaning and changing machine 100, used to house and install other components of the cutting fluid cleaning and changing machine 100 besides the body 100. The body 10 has a receiving cavity and includes a top, a bottom, and a side. The top and bottom are spaced apart and opposite each other, and in the normal use state where the cutting fluid cleaning and changing machine 100 is placed on the ground, the bottom is closer to the ground than the top. The side connects the periphery of the top and bottom, and together with the top and bottom, forms the receiving cavity. The receiving cavity 110 is used to house at least some of the aforementioned other components.

[0047] The material of the casing 10 includes, but is not limited to, metal, plastic, or a combination of both. When the casing 10 is made of metal, it has high structural strength, is less prone to damage, and provides better protection for other internal components, resulting in a long service life for the cutting fluid cleaning and changing machine 100. When the casing 10 is made of plastic, it is lighter and less expensive, giving the cutting fluid cleaning and changing machine 100 a lightweight advantage.

[0048] The moving component 20 is a component in the cutting fluid cleaning and changing machine 100 used to drive the machine body 10. The moving component 20 is mounted on the machine body 10, typically at its bottom. The moving component 20 may include a drive element and an actuator. The drive element is a power-providing component, such as a drive motor, internal combustion engine, or pneumatic motor. The actuator is a component for direct movement, such as tracks or wheels. The drive element is directly connected to the actuator and transmits power directly to the actuator to drive its movement, thereby enabling the moving component 20 to move the machine body 10. The movement of the machine body 10 by the moving component 20 can be, but is not limited to, translation, rotation, or a combination of translation and rotation. Furthermore, the moving component 20 may also include a transmission element that connects the drive element and the actuator. That is, the drive element is indirectly connected to the actuator through the transmission element, and the drive element directly transmits power to the transmission element, which then transmits it to the actuator to move it, thereby enabling the moving component 20 to move the machine body 10.

[0049] The positioning unit 30 is a component in the cutting fluid cleaning and changing machine 100 used for positioning. In this application, the positioning unit 30 is used to position the machine body 10 to the target machine 300 where the cutting fluid needs to be replaced. Since the cutting fluid cleaning and changing machine 100 is typically used in a factory with multiple machines, any one of these machines may require a cutting fluid change; that is, any one machine could become the target machine 300. Therefore, the cutting fluid cleaning and changing machine 100 needs to accurately reach the target machine 300 in order to perform operations such as fluid replacement, cleaning, and rinsing the oil tank 310. After the cutting fluid cleaning and changing machine 100 receives an instruction to perform operations such as changing fluid, cleaning slag, or cleaning the oil tank 310 on the target machine 300, the moving component 20 will drive the machine body 10 to move within the factory. When it reaches a certain machine, the positioning unit 30 will match the machine. Once the match is successful, the machine is confirmed as the target machine 300, and the moving component 20 will no longer drive the machine body 10. If the match is unsuccessful, the machine is not yet the target machine 300, and the moving component 20 will continue to drive the machine body 10 until the positioning unit 30 successfully matches the machine. In this way, the positioning unit 30 positions the machine body 10 to the target machine 300 where the cutting fluid needs to be changed.

[0050] The fluid replacement assembly 40 is a component in the cutting fluid cleaning and replacement machine 100 used to perform the replacement of the cleaning fluid. When the moving assembly 20 drives the cutting fluid cleaning and replacement machine 100 forward, and the positioning unit 30 positions the machine body 10 to the target machine 300, the fluid replacement assembly 40 can perform the following operations on the target machine 300: extracting the cutting fluid from the oil tank 310 of the target machine 300 and replenishing the oil tank 310 with cutting fluid. The cutting fluid replenished into the oil tank 310 can be of various types. In some embodiments, the cutting fluid replenished into the oil tank 310 can be unused, brand-new, uncontaminated cutting fluid. In other embodiments, the cutting fluid replenished into the oil tank 310 can be unused cutting fluid with slight contamination, but the degree of contamination is sufficient for the machining needs of the target machine 300. In still other embodiments, the cutting fluid replenished into the oil tank 310 can be used cutting fluid with slight contamination, but the degree of contamination is sufficient for the machining needs of the target machine 300. In some other embodiments, the cutting fluid added to the oil tank 310 can be a used cutting fluid with a high degree of contamination, but which, after certain treatment, has a degree of contamination reduced to meet the machining needs of the target machine tool 300.

[0051] Furthermore, in actual use, depending on the application scenario, the fluid exchange component 40 of the cutting fluid cleaning and changing machine 100 can perform one or both of the following operations: extracting cutting fluid from the oil tank 310 of the target machine 300 and replenishing cutting fluid to the oil tank 310 of the target machine 300. Specifically, in one scenario, if the cutting fluid of the target machine 300 is contaminated and the target machine 300 needs to continue operating, the fluid exchange component 40 first extracts the cutting fluid from the oil tank 310 of the target machine 300, and then replenishes the oil tank 310 of the target machine 300 with cutting fluid. In another scenario, if the cutting fluid of the target machine 300 is contaminated and the target machine 300 does not need to continue operating, the fluid exchange component 40 only extracts the cutting fluid from the oil tank 310 of the target machine 300. In yet another scenario, if the target machine 300 has no cutting fluid, the fluid exchange component 40 only replenishes the oil tank 310 of the target machine 300 with cutting fluid.

[0052] Image acquisition unit 50 is a unit in the cutting fluid cleaning and replacement machine 100 used for image acquisition. In this application, image acquisition unit 50 is used to acquire a first image containing the oil tank 310, which is used to confirm the degree of dirtiness of the oil tank 310 of the target machine 300. Since the target machine 300 usually uses circulating cutting fluid, new impurities generated during the circulation process and long-term deposited impurities will be distributed in the oil tank 310, which may affect the circulation of the cutting fluid. Therefore, it is necessary to determine whether the oil tank 310 needs to be cleaned based on the degree of dirtiness. When the oil tank 310 is heavily dirty, the cutting fluid cleaning and replacement machine 100 will clean the oil tank 310 when operating on the target machine 300 to ensure the processing quality of the target machine 300. When the oil tank 310 is only slightly dirty, the cutting fluid cleaning and changing machine 100 does not need to clean the oil tank 310 when operating on the target machine 300, so as to shorten the operation time and save costs.

[0053] Specifically, the image acquisition unit 50 includes a camera. The image acquisition unit 50 is mounted on the machine body 10, typically on the top or side of the machine body 10, to ensure that the captured first image clearly shows the characteristics of the oil tank 310, facilitating subsequent analysis and processing. In some embodiments, the cutting fluid cleaning and changing machine 100 also includes a processor, which can be integrated inside the image acquisition unit 50 or mounted on the machine body 10, but located outside the image acquisition unit 50. The processor communicates with the camera (either wired or wirelessly). After the camera captures the first image, the processor processes and analyzes the first image to determine the degree of dirtiness in the oil tank 310 of the target machine 300. In other embodiments, the first image captured by the image acquisition unit 50 is transmitted to the cloud, where a cloud processor processes and analyzes the first image to determine the degree of dirtiness in the oil tank 310 of the target machine 300. The degree of dirtiness of the oil tank 310 can be measured by the percentage of dirt covering the surface of the oil tank 310. The higher the percentage, the deeper the dirtiness, and vice versa.

[0054] The cleaning component 60 is used in the cutting fluid cleaning and changing machine 100 to clean the oil tank 310. The cleaning component 60 is mounted on the machine body 10, and its position corresponds to that of the oil tank 310, ensuring that the cleaning component 60 can be aligned with the oil tank 310 for cleaning, thus improving cleaning efficiency and effectiveness. The cleaning method of the cleaning component 60 for cleaning the oil tank 310 can be, but is not limited to, liquid rinsing or bubble rinsing. When the image acquisition unit 50 acquires a first image, the cutting fluid cleaning and changing machine 100 identifies the degree of dirt in the oil tank 310 based on the first image and obtains an identification result, that is, quantifies the degree of dirt in the oil tank 310 into a specific value, and compares this quantified value with a preset threshold. The preset threshold is used to determine whether the degree of dirt in the oil tank 310 has reached the level requiring cleaning. The preset threshold can be set before the cutting fluid cleaning and changing machine 100 leaves the factory, or it can be set by the user through an input interface after the cutting fluid cleaning and changing machine 100 leaves the factory. When the degree of dirt in the oil tank 310 reaches a preset threshold, the degree of dirt in the oil tank 310 is relatively deep and needs to be cleaned by the cleaning component 60. At this time, the cleaning component 60 can clean the oil tank 310.

[0055] Furthermore, in some embodiments, the cutting fluid cleaning and replacement machine 100 of this application can interact with a central control system, and the central control system can remotely control it to obtain instruction information for operating the target machine 300. The central control system can intelligently schedule and programmatically manage the cutting fluid cleaning and replacement machine 100, improving the efficiency and accuracy of production management. In other embodiments, the cutting fluid cleaning and replacement machine 100 may also include a programmable logic controller (PLC), which can be the aforementioned processor or a controller independent of the aforementioned processor. Before the cutting fluid cleaning and replacement machine 100 leaves the factory, the execution program of the cutting fluid cleaning and replacement machine 100 is pre-set in the PLC. For example, the frequency at which the cutting fluid cleaning and replacement machine 100 needs to perform one or more of the following operations on one or more designated machines: cutting fluid replacement, cleaning, and cleaning of the oil tank 310. During the use of the cutting fluid cleaning and changing machine 100, the execution content of the machine 100 can be adjusted by modifying the execution program inside the PLC. For example, when the usage frequency of the target machine 300 decreases, the frequency of fluid changing operations performed by the cutting fluid cleaning and changing machine 100 on the target machine 300 will decrease accordingly. In this way, the entire operation process of the cutting fluid cleaning and changing machine 100 is carried out under the control of the PLC, realizing the automated control of the operation process of the cutting fluid cleaning and changing machine 100, saving time and labor costs.

[0056] The cutting fluid cleaning and replacement machine 100 of this application first moves the machine body 10 using the moving component 20, and then positions the machine body 10 to the target machine 300 where the cutting fluid needs to be replaced using the positioning unit 30. Then, the replacement component 40 extracts the cutting fluid from the oil tank 310 of the target machine 300. Next, the image acquisition unit 50 captures a first image containing the oil tank 310 and uses the first image to identify the degree of dirtiness in the oil tank 310. When the degree of dirtiness in the oil tank 310 reaches a preset threshold, the cleaning component 60 cleans the oil tank 310. Finally, the replacement component 40 replenishes the cutting fluid in the oil tank 310. The entire replacement process is completed automatically without human intervention, saving time, labor, and costs.

[0057] Please refer to Figure 1 In some embodiments, the positioning unit 30 includes a scanner 31, which scans the identification codes on the machine to position the machine body 10 to the target machine 300. In the factory using the cutting fluid cleaning and changing machine 100, each machine has an identification code on its outer surface for identifying the machine. These identification codes include, but are not limited to, QR codes or barcodes. After the identification code on each machine is scanned by the scanner 31, it is matched with the identification code of the target machine 300 carried in the instruction information. If the match is successful, the currently scanned machine is determined to be the target machine 300; if the match fails, the currently scanned machine is determined not to be the target machine 300. Therefore, the scanner 31 accurately positions the machine body 10 to the target machine 300 by scanning the identification code on the machine base, so as to realize the cooperation between the cutting fluid cleaning and changing machine 100 and the target machine 300, thereby enabling the cutting fluid cleaning and changing machine 100 to perform subsequent operations such as changing fluid, cleaning slag or cleaning oil tank 310 on the target machine 300.

[0058] Please refer to Figure 2In some embodiments, the positioning unit 30 includes a camera 33, which is used to capture a second image containing the machine tool. The second image is used to position the machine body 10 to the target machine tool 300. In a factory using the cutting fluid cleaning and replacement machine 100, the shapes and locations of the various machines are not entirely the same. The second image captured by the camera 33 can reflect the shape and location information of the currently captured machine tool. If the shape and location information of the currently captured machine tool is the same as the shape and location information of the target machine tool 300 carried in the instruction information, then the currently captured machine tool is determined to be the target machine tool 300. If the shape and location information of the currently captured machine tool is different from at least one of the shape and location information of the target machine tool 300, then the currently captured machine tool is determined not to be the target machine tool 300. Therefore, the camera 33 can accurately position the machine body 10 to the target machine 300 through the captured second image, so as to realize the cooperation between the cutting fluid cleaning and changing machine 100 and the target machine 300, thereby enabling the cutting fluid cleaning and changing machine 100 to perform subsequent operations such as changing fluid, cleaning slag or cleaning oil tank 310 on the target machine 300.

[0059] Please refer to Figure 3 In some embodiments, the positioning unit 30 includes a transceiver 35, which transmits signals to the machine and receives signals fed back from the machine. The fed-back signals are used to position the machine body 10 to the target machine 300. The transceiver 35 is a component with the function of transmitting and receiving signals. The signals transmitted and received by the transceiver 35 can be, but are not limited to, light waves and sound waves. In the factory where the cutting fluid cleaning and changing machine 100 is used, each machine is equipped with a communication unit. When the transceiver 35 transmits signals to the machine, the communication unit can send signals back to the transceiver 35. The transceiver 35 receives the signals fed back from the machine and determines whether each machine is the target machine 300 based on the fed-back signals. For example, the fed-back signal contains the identification code of the current machine. The identification code in the fed-back signal is matched with the identification code of the target machine 300 carried in the instruction information. If the match is successful, the current machine is determined to be the target machine 300; if the match fails, the current machine is determined not to be the target machine 300. Therefore, the transceiver 35 can accurately position the machine body 10 to the target machine 300 by acquiring the feedback signal, so as to realize the cooperation between the cutting fluid cleaning and changing machine 100 and the target machine 300, thereby enabling the cutting fluid cleaning and changing machine 100 to perform subsequent operations such as changing fluid, cleaning slag or cleaning oil tank 310 on the target machine 300.

[0060] Please refer to Figures 1 to 3In some embodiments, the cutting fluid cleaning and changing machine 100 also includes an optical sensor 70. The optical sensor 70 is disposed on the machine body 10 and is used to capture a third image when the machine body 10 moves, the third image being used to identify obstacles in the moving path of the machine body 10.

[0061] Specifically, in the above-described embodiment, the process of the machine body 10 moving to the target machine 300 requires the movement of the moving component 20. In the factory where the cutting fluid cleaning and changing machine 100 is used, there are usually not only multiple machines installed, but also other objects such as walls, other equipment, and workers. These objects will inevitably become obstacles in the movement of the machine body 10. Therefore, the machine body 10 needs to avoid obstacles that already exist or suddenly appear on its path as it moves to the target machine 300. The optical sensor 70 is an element in the cutting fluid cleaning and changing machine 100 used to capture a third image containing information about the surrounding environment. The optical sensor 70 is mounted on the machine body 10, and is usually located on the front side of the machine body 10, to ensure that the optical sensor 70 can fully acquire images of obstacles on the path. The third image can be used to identify obstacles on the path of the machine body 10, thereby ensuring the smooth progress of the machine body 10 moving to the target machine 300, and thus improving the intelligence, operating efficiency, and operating safety of the cutting fluid cleaning and changing machine 100.

[0062] Please refer to Figures 1 to 4 In some embodiments, the fluid exchange assembly 40 includes a first storage unit 41, a second storage unit 43, a fluid exchange pump 45, and a fluid exchange head 47. The first storage unit 41 is disposed in the machine body 10 and forms a storage cavity 411. The second storage unit 43 is disposed in the machine body 10 and is used to store cutting fluid to be replenished. The fluid exchange pump 45 is disposed inside the machine body 10 and communicates with the storage cavity 411. The fluid exchange head 47 communicates with the fluid exchange pump 45 and extends outside the machine body 10. The fluid exchange head 47 can extend and retract relative to the machine body 10. The fluid exchange pump 45 is used to draw cutting fluid from the oil tank 310 into the storage cavity 411 through the fluid exchange head 47, and to draw cutting fluid to be replenished from the second storage unit 43 and output it to the oil tank 310 through the fluid exchange head 47.

[0063] Specifically, in the above embodiment, the first storage component 41 is a component in the fluid exchange assembly 40 used to store cutting fluid (used cutting fluid) or cleaning fluid (used cleaning fluid) drawn from the oil tank 310. The first storage component 41 is located on the machine body 10. Figure 1Taking the first storage component 41 as an example, which is located on the top of the machine body 10, the first storage component 41 can also be located on the side of the machine body 10 or in a receiving cavity of the machine body 10. The first storage component 41 is a structure with a storage space, namely a storage cavity 411, which is used to store cutting fluid or cleaning fluid drawn from the oil tank 310. The storage cavity 411 is provided with an inlet for the cutting fluid or cleaning fluid to enter the storage cavity 411. In some embodiments, the first storage component 41 is also provided with a drain port 413, which is an opening for removing liquid from the storage cavity 411.

[0064] The second storage unit 43 is a component in the fluid exchange assembly 40 used to store the cutting fluid to be replenished in the oil inlet 310. The second storage unit 43 is located on the machine body 10. Figure 1 Taking the second storage component 43 as an example, which is located on the top of the machine body 10, the second storage component 43 can also be located on the side of the machine body 10 or in the receiving cavity of the machine body 10. The second storage component 43 is a structure with a storage space for storing cutting fluid to be replenished. As mentioned above, the cutting fluid stored in the second storage component 43 can be of various types. The second storage component 43 is provided with an outlet for the cutting fluid to flow out of the second storage component 43. In some embodiments, the second storage component 43 is also provided with an injection port 431, which is an opening for injecting the cutting fluid to be replenished into the second storage component 43.

[0065] The fluid exchange pump 45 is a structure in the fluid exchange assembly 40 used to pump liquid into the first storage unit 41 or pump liquid out of the second storage unit 43. The fluid exchange pump 45 is disposed in the receiving cavity of the body 10 and connected to both the first storage unit 41 and the second storage unit 43. Specifically, the fluid exchange pump 45 communicates with the storage cavity 411 of the first storage unit 41 and with the storage space of the second storage unit 43. The fluid exchange head 47 is a component used to cooperate with the fluid exchange pump 45 to accurately guide the liquid driven by the fluid exchange pump 45. The fluid exchange head 47 passes through the body 10. At least a portion of the structure of the fluid exchange head 47 located inside the body 10 communicates with the fluid exchange pump 45 and forms a passage for liquid flow. At least a portion of the structure of the fluid exchange head 47 located outside the body 10 is provided with openings for liquid inflow or outflow. The fluid changing head 47 can move according to the working state of the cutting fluid cleaning and changing machine 100. Specifically, when the cutting fluid cleaning and changing machine 100 needs to draw cutting fluid from the oil tank 310 of the target machine 300 into the storage chamber 411, and when the cutting fluid cleaning and changing machine 100 needs to inject cutting fluid into the oil tank 310 of the target machine 300, the fluid changing head 47 can extend relative to the machine body 10 to cooperate with the oil tank 310. After the cutting fluid cleaning and changing machine 100 completes the fluid changing operation on the target machine 300, the fluid changing head 47 can retract relative to the machine body 10 to avoid damage to the fluid changing head 47 due to external forces.

[0066] In the case where the cutting fluid cleaning and changing machine 100 of this application draws cutting fluid from the oil tank 310 of the target machine 300, the changing pump 45 draws the cutting fluid from the oil tank 310 into the storage chamber 411 through the changing head 47. The flow path of the cutting fluid during this process is as follows: Figure 4 As shown by the solid arrow, when the cutting fluid cleaning and replacement machine 100 of this embodiment injects cutting fluid into the oil tank 310 of the target machine 300, the replacement pump 45 draws the cutting fluid to be replenished from the second storage unit 43 and injects it into the oil tank 310 through the replacement head 47. The flow path of the cutting fluid to be replenished during this process is as follows: Figure 4 As shown by the dashed arrow.

[0067] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 In other embodiments, the fluid exchange assembly 40 includes a centrifugal filter 49, a fluid exchange pump 45, and a fluid exchange head 47. The centrifugal filter 49 is disposed within the machine body 10 and has a filter chamber 491, an inlet 493, an outlet 495, and a slag removal port 497. The centrifugal filter 49 is used to centrifugally filter the cutting fluid entering the filter chamber 491. The fluid exchange pump 45 is disposed within the machine body 10 and communicates with both the inlet 493 and the outlet 495. The fluid exchange head 47 communicates with the fluid exchange pump 45 and extends outside the machine body 10, allowing it to extend and retract relative to the machine body 10. The fluid exchange pump 45 is used to draw cutting fluid from the oil tank 310 through the fluid exchange head 47 and transport it from the inlet 493 to the filter chamber 491, and to draw centrifugally filtered cutting fluid from the filter chamber 491 through the outlet 495 and output it to the oil tank 310 through the fluid exchange head 47. The slag outlet 497 is used to remove the filter residue after centrifugation in the filter chamber 491.

[0068] Specifically, in the above embodiment, the centrifugal filter 49 is a component used to centrifuge and filter the cutting fluid drawn from the oil tank 310 of the target machine 300 to remove impurities. The centrifugal filter 49 is disposed on the machine body 10. Figure 1Taking a centrifugal filter element 49 located at the top of the machine body 10 as an example, the filter chamber 491 of the centrifugal filter element 49 is used to contain the cutting fluid drawn from the oil tank 310 of the target machine 300, and to perform centrifugation and filtration operations on the cutting fluid therein. During centrifugation, due to the different centrifugal forces experienced by the cutting fluid and impurities, the impurities can be separated from the cutting fluid. The filter chamber 491 is equipped with specific filtration structures such as filter frames, filter screens, and filter tanks to filter out the cutting fluid and impurities simultaneously during centrifugation. In addition, the centrifugal filter element 49 also includes an inlet 493, an outlet 495, and a slag removal port 497. The inlet 493 is used to allow the cutting fluid drawn from the oil tank 310 to enter the filter chamber 491, the outlet 495 is used to allow the cutting fluid after centrifugal filtration to flow out of the filter chamber 491, and the slag removal port 497 is used to remove the filter slag produced after centrifugal filtration. Since the filter residue is separated from the cutting fluid and has no other use afterward, the cutting fluid cleaning and replacement machine 100 removes the filter residue from the residue removal port 497 during or at the end of the aforementioned operation to prevent the filter residue from accumulating in the centrifugal filter element 49 and affecting the next centrifugal filtration operation.

[0069] The fluid exchange pump 45 is connected to the centrifugal filter element 49, specifically, the fluid exchange pump 45 is connected to both the inlet 493 and the outlet 495 of the centrifugal filter element 49. At this time, the fluid exchange pump 45 can pump the cutting fluid drawn from the oil tank 310 of the target machine 300 into the inlet 493 of the centrifugal filter element 49, and pump the cutting fluid that has undergone centrifugal filtration in the centrifugal filter element 49 back into the oil tank 310 from the outlet 495 of the centrifugal filter element 49. The fluid exchange head 47 can move according to the working state of the cutting fluid cleaning and fluid exchange machine 100. Specifically, when the cutting fluid cleaning and fluid exchange machine 100 needs to draw cutting fluid from the oil tank 310 of the target machine 300 into the centrifugal filter element 49, or when the cutting fluid cleaning and fluid exchange machine 100 needs to inject cutting fluid into the oil tank 310 of the target machine 300, the fluid exchange head 47 can extend relative to the machine body 10 to cooperate with the oil tank 310. When the cutting fluid cleaning and changing machine 100 completes the fluid changing operation on the target machine 300, the changing head 47 can retract relative to the machine body 10 to avoid damage to the changing head 47 due to external force.

[0070] In the case where the cutting fluid cleaning and changing machine 100 of this application draws cutting fluid from the oil tank 310 of the target machine 300, the changing fluid pump 45 draws the cutting fluid from the oil tank 310 through the changing fluid head 47 and delivers it from the inlet 493 to the filter chamber 491 of the centrifugal filter element 49. The flow path of the cutting fluid during this process is as follows: Figure 5As shown by the solid arrow, the centrifugal filter 49 centrifuges and filters the cutting fluid flowing into the filter chamber 491 to remove impurities. In the case where the cutting fluid cleaning and changing machine 100 of this embodiment injects the filtered cutting fluid into the oil tank 310 of the target machine 300, the changing pump 45 draws the centrifugally filtered cutting fluid from the filter chamber 491 from the outlet 495 and injects it into the oil tank 310 through the changing head 47. The flow path of the centrifugally filtered cutting fluid during this process is as follows: Figure 5 The single-dot dashed arrow is shown. The slag outlet 497 is used to remove the filter residue produced after centrifugal filtration in the filter chamber 491, as shown... Figure 5 As shown by the dashed arrow.

[0071] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 In some embodiments, the fluid exchange assembly 40 includes a centrifugal filter 49, a first storage unit 41, a fluid exchange pump 45, and a fluid exchange head 47. The centrifugal filter 49 is disposed in the machine body 10 and has a filter chamber 491, an inlet 493, an outlet 495, and a slag removal port 497. The centrifugal filter 49 is used to centrifugally filter the cutting fluid entering the filter chamber 491. The first storage unit 41 is disposed in the machine body 10 and forms a storage chamber 411. The storage chamber 411 communicates with the outlet 495. The fluid exchange pump 45 is disposed inside the machine body 10 and communicates with the inlet 493. The fluid exchange head 47 communicates with the fluid exchange pump 45 and extends outside the machine body 10. The fluid exchange head 47 can extend and retract relative to the machine body 10. The fluid exchange pump 45 is used to draw cutting fluid from the oil tank 310 through the fluid exchange head 47 and deliver it to the filter chamber 491 through the inlet 493, and to draw centrifugally filtered cutting fluid from the storage chamber 411 and output it to the oil tank 310 through the fluid exchange head 47. The slag removal port 497 is used to remove the filter slag after centrifugation in the filter chamber 491.

[0072] The centrifugal filter element 49 is explained as before and will not be repeated here. The first storage element 41 is also used to store the cutting fluid after centrifugal filtration. The first storage element 41 is located on the machine body 10. Figure 1 Taking the first storage unit 41 located on the top of the machine body 10 as an example, the first storage unit 41 has a storage space, namely the storage cavity 411, which is used to store the cutting fluid after centrifugation and filtration by the centrifugal filter 49. The storage cavity 411 is provided with a connecting port 415, which is connected to the outlet 495 of the centrifugal filter 49 so that the centrifugally filtered cutting fluid can enter the storage cavity 411. That is, the cutting fluid after centrifugation and filtration by the centrifugal filter 49 enters the first storage unit 41 through the outlet 495 and the connecting port 415 for subsequent replenishment into the oil tank 310, while the filter residue is left in the centrifugal filter 49 to be removed later through the residue removal port 497.

[0073] In the case where the cutting fluid cleaning and changing machine 100 of this application draws cutting fluid from the oil tank 310 of the target machine 300, the changing fluid pump 45 draws the cutting fluid from the oil tank 310 through the changing fluid head 47 and delivers it from the inlet 493 to the filter chamber 491 of the centrifugal filter element 49. The flow path of the cutting fluid during this process is as follows: Figure 6 As shown by the solid arrow, the centrifugal filter 49 centrifuges the cutting fluid to remove impurities. The centrifugally filtered cutting fluid enters the first storage unit 41 for storage through the outlet 495 and the connecting port 415. When the cutting fluid cleaning and changing machine 100 of this embodiment injects the centrifugally filtered cutting fluid into the oil tank 310 of the target machine 300, the changing pump 45 draws the centrifugally filtered cutting fluid from the storage chamber 411 of the first storage unit 41 and injects it into the oil tank 310 through the changing head 47. The flow path of the centrifugally filtered cutting fluid during this process is as follows: Figure 6 The single-dot dashed arrow is shown. The slag outlet 497 is used to remove the filter residue after centrifugal filtration in the filter chamber 491, as shown... Figure 6 As shown by the dashed arrow.

[0074] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 7 In some embodiments, the cleaning assembly 60 includes a third storage unit 61, a cleaning pump 63, and a cleaning head 65. The third storage unit 61 is disposed within the machine body 10 and is used to store cleaning fluid. The cleaning pump 63 is disposed within the machine body 10 and communicates with the third storage unit 61. The cleaning head 65 communicates with the cleaning pump 63 and extends outside the machine body 10. The cleaning pump 63 is used to draw cleaning fluid from the third storage unit 61 and inject cleaning fluid into the oil tank 310 through the cleaning head 65.

[0075] Specifically, in the above embodiment, the third storage component 61 is a component in the cleaning assembly 60 used to store the cleaning fluid. The cleaning fluid is a liquid used to clean the oil tank 310 of the target machine 300, and the cleaning fluid may include, but is not limited to, clean water, a mixture of clean water and detergent, or a mixture of clean water and care solution, etc. The third storage component 61 is located on the machine body 10. Figure 1 Taking the example of the third storage component 61 being located at the top of the body 10, the third storage component 61 can also be located on the side of the body 10 or within the receiving cavity of the body 10. The third storage component 61 has a storage space for storing cleaning fluid. The third storage component 61 has an outlet for the cleaning fluid to flow out. In some embodiments, the third storage component 61 also has an inlet 611, which is an opening for replenishing cleaning fluid into the third storage component 61.

[0076] The cleaning pump 63 is a structure in the cleaning assembly 60 used to pump cleaning fluid from the third storage unit 61 and into the oil tank 310. The cleaning pump 63 is disposed in the receiving cavity of the machine body 10 and is connected to both the second storage unit 43 and the cleaning head 65. Specifically, the cleaning pump 63 connects the storage space of the third storage unit 61 with the cleaning head 65. The cleaning head 65 is a component used to cooperate with the cleaning pump 63 to accurately guide the cleaning fluid pumped out by the cleaning pump 63. The cleaning head 65 extends through the machine body 10. At least a portion of the structure of the cleaning head 65 located inside the machine body 10 is connected to the cleaning pump 63, forming a passage for the cleaning fluid to flow through. At least a portion of the structure of the cleaning head 65 located outside the machine body 10 must be provided with an opening for the cleaning fluid to flow out. The cleaning head 65 can inject the cleaning fluid pumped by the cleaning pump 63 from the third storage unit 61 into the oil tank 310 of the target machine 300 to achieve cleaning of the oil tank 310 by the cleaning fluid.

[0077] The cleaning power of the cleaning fluid on the oil tank 310 is related to the method by which the cleaning head 65 injects the cleaning fluid into the oil tank 310 and the treatment method of the cleaning fluid in the oil tank 310. When the cleaning head 65 injects the cleaning fluid into the oil tank 310 by high-pressure rinsing, the cleaning fluid can exert a greater force on the sludge and impurities in the oil tank 310, thereby fully peeling off the sludge and impurities from the inner wall of the oil tank 310 and flushing them out of the oil tank 310. When the cleaning fluid circulates within the oil tank 310 after being injected, the cleaning fluid can soak the sludge and impurities in the oil tank 310 for a long time. Therefore, the cleaning fluid and the sludge and impurities can act for a long time, and the sludge and impurities can be peeled off from the inner wall of the oil tank 310. At the same time, the circulating cleaning fluid can also accelerate the process of peeling off the sludge and impurities from the inner wall of the oil tank 310.

[0078] Before the fluid replacement assembly 40 of the cutting fluid cleaning and fluid replacement machine 100 of this application replenishes the cutting fluid in the oil tank 310, and when the cleaning assembly 60 injects cleaning fluid into the oil tank 310 of the target machine 300, the cleaning pump 63 draws cleaning fluid from the third storage unit 61 and injects the drawn cleaning fluid into the oil tank 310 through the cleaning head 65 to effectively clean the oil tank 310, so that the sludge and impurities in the oil tank 310 are fully removed. The flow path of the cleaning fluid during this process is as follows: Figure 7 As shown by the single-dot dashed arrow. Therefore, before replacing the cutting fluid on the target machine 300, the cutting fluid cleaning and replacement machine 100 of this application can clean the oil tank 310 using the cleaning component 60 to ensure that the replenished cutting fluid will not be contaminated again by the dirt in the oil tank 310, thus ensuring that the cutting fluid replaced on the target machine 300 has good performance. Therefore, the processing performance of the target machine 300 is guaranteed, and the quality of the processed workpiece is also guaranteed.

[0079] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 8 Furthermore, in some embodiments, the cutting fluid cleaning and changing machine 100 may further include a first storage unit 41, a changing fluid pump 45, and a changing fluid head 47. The first storage unit 41 is disposed in the machine body 10 and forms a storage cavity 411. The changing fluid pump 45 is disposed inside the machine body 10 and communicates with the storage cavity 411. The changing fluid head 47 communicates with the changing fluid pump 45 and extends outside the machine body 10. The changing fluid head 47 can extend and retract relative to the machine body 10. The changing fluid pump 45 is used to draw cleaning fluid from the oil tank 310 into the storage cavity 411 through the changing fluid head 47.

[0080] Specifically, in the above embodiment, the first storage unit 41 is also used to store components contaminated with cleaning fluid after cleaning the oil tank 310. The first storage unit 41 is located on the machine body 10. Figure 1 Taking the first storage component 41 located on the top of the body 10 as an example, the first storage component 41 has a storage space, namely the storage cavity 411, which is used to store the cleaning fluid that becomes contaminated after cleaning the oil tank 310. The storage cavity 411 is provided with an inlet, which is connected to the fluid exchange pump 45 to allow the cleaning fluid to enter the storage cavity 411. At this time, after the cleaning fluid has completed cleaning the oil tank 310 in the oil tank 310 and carried at least some impurities, the fluid exchange pump 45 transports the cleaning fluid in the oil tank 310 into the storage cavity 411 through the fluid exchange head 47. Subsequently, the cleaning fluid in the storage cavity 411 can be discharged from the drain port 413. The discharged cleaning fluid can be reused or directly discharged after environmental treatment.

[0081] In the cutting fluid cleaning and replacement machine 100 of this application embodiment, after the oil tank 310 is cleaned by the cleaning assembly 60, that is, after the cleaning pump 63 draws the cleaning fluid from the third storage unit 61 and injects the cleaning fluid into the oil tank 310 through the cleaning head 65 (the flow path of the cleaning fluid during this process is as follows...), Figure 8 As shown by the dashed arrow, the fluid exchange pump 45 draws cleaning fluid from the oil tank 310 through the fluid exchange head 47 and delivers it from the inlet of the first storage unit 41 into the storage chamber 411 (the flow path of the cleaning fluid during this process is as follows). Figure 8 As shown by the double-dotted arrow, the cleaning fluid in the storage chamber 411 can be discharged from the drain port 413. After the cleaning fluid is discharged, it can be reused or directly discharged after environmental protection treatment.

[0082] Subsequently, the cutting fluid cleaning and replacement machine 100 of this application embodiment can also be as follows: Figure 4The implementation method is the same as shown: the fluid exchange pump 45 draws the cutting fluid to be replenished from the second storage unit 43 and injects it into the oil tank 310 through the fluid exchange head 47. The flow path of the cutting fluid to be replenished during this process is as follows: Figure 4 As shown by the dashed arrow. The cutting fluid cleaning and changing machine 100 of this application embodiment can also be as follows: Figure 5 The implementation method is the same as shown: the fluid exchange pump 45 draws the centrifugally filtered cutting fluid from the filter chamber 491 through the outlet 495 and injects it into the oil tank 310 through the fluid exchange head 47. The flow path of the centrifugally filtered cutting fluid during this process is as follows: Figure 5 As shown by the single-dot dashed arrow. The cutting fluid cleaning and changing machine 100 of this application embodiment can also be as follows: Figure 6 The implementation method is the same as shown: the fluid exchange pump 45 draws centrifugally filtered cutting fluid from the storage chamber 411 of the first storage unit 41 and injects it into the oil tank 310 through the fluid exchange head 47. The flow path of the centrifugally filtered cutting fluid during this process is as follows: Figure 6 The single-dot dashed arrow is shown.

[0083] Therefore, the cutting fluid cleaning and replacement machine 100 of this embodiment can clean the oil tank 310 using the cleaning component 60 before replacing the cutting fluid on the target machine 300. This ensures that the replenished cutting fluid will not be contaminated again by the dirt in the oil tank 310, thus ensuring that the cutting fluid on the target machine 300 has good performance after replacement. Therefore, the machining performance of the target machine 300 is guaranteed, and the quality of the machined workpieces is also guaranteed. At the same time, the cutting fluid cleaning and replacement machine 100 of this embodiment can also automatically recover the cleaning fluid after cleaning, avoiding contamination of the target machine 300 and its surrounding environment. Moreover, the recovery process is fully automatic and requires no manual operation, further saving time, labor, and costs.

[0084] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 7 In some embodiments, the first image acquired by the image acquisition unit 50 is also used to identify dirty areas in the oil tank 310. The cleaning pump 63 is also used to extract cleaning fluid from the third storage unit 61 and rinse the dirty areas through the cleaning head 65.

[0085] In this application, the image acquisition unit 50 acquires a first image of the oil tank 310 before the fluid exchange assembly 40 replenishes the oil tank 310 with cutting fluid. This first image can be used not only to identify the degree of dirt in the oil tank 310 but also to identify specific dirty areas within the oil tank 310, i.e., the specific location of the dirt distribution within the oil tank 310. Similarly, after the camera of the image acquisition unit 50 captures the first image, the processor of the cutting fluid cleaning and fluid exchange machine 100 processes and analyzes the first image to determine the dirty areas of the oil tank 310 of the target machine 300. At this time, the cleaning pump 63 draws cleaning fluid from the third storage unit 61 and adjusts the position of the cleaning head 65 so that the cleaning fluid output direction of the cleaning head 65 is directly aligned with the specific location of the dirt distribution in the oil tank 310. Therefore, the cleaning head 65 can specifically flush the dirty areas in the oil tank 310 with the cleaning fluid, achieving efficient and precise cleaning of the oil tank 310.

[0086] Please refer to Figures 1 to 3 In some embodiments, the cleaning head 65 can extend and retract relative to the machine body 10. When the cutting fluid cleaning and changing machine 100 injects cleaning fluid into the oil tank 310 of the target machine 300, the cleaning head 65 can extend relative to the machine body 10 to cooperate with the oil tank 310, ensuring that the cleaning fluid is accurately injected into the oil tank 310, or accurately rinsing the dirty areas in the oil tank 310. After the cutting fluid cleaning and changing machine 100 has completed injecting cleaning fluid into the oil tank 310 or rinsing the dirty areas in the oil tank 310, the cleaning head 65 can retract relative to the machine body 10 to avoid damage to the cleaning head 65 from external forces.

[0087] Please refer to Figures 1 to 3 In other embodiments, the cleaning head 65 is capable of rotation and / or translation relative to the machine body 10. When the coolant cleaning and changing machine 100 injects cleaning fluid into the oil tank 310 of the target machine 300, the cleaning head 65 can adjust the angle at which it outputs the cleaning fluid by rotating relative to the machine body 10, or by translating relative to the machine body 10, or by rotating and translating relative to the machine body 10, to ensure that the cleaning fluid is accurately injected into the oil tank 310, or accurately rinses the dirty areas in the oil tank 310. After the coolant cleaning and changing machine 100 has completed injecting cleaning fluid into the oil tank 310 or rinsing the dirty areas in the oil tank 310, the cleaning head 65 can rotate and / or translate relative to the machine body 10 to return to its initial position (e.g., partially housed within the receiving cavity of the machine body 10), preventing damage to the cleaning head 65 from external forces.

[0088] Please refer to Figures 1 to 3In some embodiments, the cleaning head 65 is provided with multiple liquid outlets. The liquid outlet is an opening on the cleaning head 65 for discharging cleaning fluid. In the embodiments of this application, the cleaning head 65 has multiple liquid outlets to allow for a wider coverage area and a larger output volume of cleaning fluid. Specifically, the liquid outlets can be evenly distributed circumferentially around the cleaning head 65. In this case, the cleaning head 65 can evenly discharge cleaning fluid circumferentially, allowing the cleaning fluid to simultaneously rinse a larger area of ​​the oil tank 310, thus enabling the cleaning assembly 60 to quickly and uniformly clean the oil tank 310 over a large area.
