Description

Technical Field

[0001] This invention relates to a fluid replenishment system and a self-propelled fluid replenishment device. Background Technology

[0002] Generally speaking, a self-propelled coolant replenishment device is a type of Automated Guided Vehicle (AGV), typically referring to equipment with automated movement capabilities (such as AMR / Autonomous Mobile Robot) that can perform coolant replenishment operations in factories, servers, or production areas. For example, a self-propelled coolant replenishment device can automatically move to a server and exchange coolant in any cooling distribution unit on the server's cabinet.

[0003] However, since the positions of the inlet and outlet of the cooling distribution units vary for different specifications, the outlet and inlet connectors of the self-propelled replenishment device cannot be matched with the inlet and outlet of all specifications of cooling distribution units. This limits the service range of the self-propelled replenishment device and reduces its flexibility in cooperating with various servo devices.

[0004] Therefore, developing a solution to improve the aforementioned deficiencies and inconveniences is an urgent and important issue for relevant businesses. Utility Model Content

[0139] Several embodiments of the present invention will be disclosed below with reference to the drawings. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit the present invention. That is, these practical details are not essential in the embodiments of the present invention. In addition, for the sake of simplicity, some conventional structures and elements will be shown in the drawings in a simple schematic manner.

[0140] Figure 1 This is a perspective view of a self-propelled liquid replenishment device 40 according to an embodiment of the present invention. Figure 2A and Figure 2B They are respectively Figure 1 The usage diagram for region M. (See attached diagram.) Figure 1 and Figure 2A As shown, the self-propelled liquid replenishment device 40 includes a working body 100, a moving mechanism 200, a first liquid tank 310, a second liquid tank 320, a robotic arm 500, a first connector assembly 600, a second connector assembly 700, a telescopic rod 900, a first pipeline assembly A1, and a second pipeline assembly A2. The moving mechanism 200 is mounted on the working body 100 and is used to move to a designated position. The moving mechanism 200 may be, for example, a drive motor and wheels, or other conventional technology. The first liquid tank 310 is mounted on the placement surface 110 of the working body 100 and is used to hold the liquid to be replenished (e.g., coolant). The second liquid tank 320 is mounted on the placement surface 110 of the working body 100 and is used to hold the recovered liquid (e.g., waste liquid). The robotic arm 500 is mounted on the placement surface 110 of the working body 100. The first connector assembly 600 is mounted on the robotic arm 500 and is used to connect to the inlet end (not shown) of the liquid to be replenished. The second connector group 700 is parallel to the first connector group 600 and is used to connect to the outlet end (not shown in the figure) of the liquid replenishment target. The first pipeline group A1 connects the first liquid tank 310 and the first connector group 600. The second pipeline group A2 connects the second liquid tank 320 and the second connector group 700. The telescopic rod 900 connects the first connector group 600 and the second connector group 700 respectively. Depending on the relative position of the inlet and outlet ends, the telescopic rod 900 can linearly push or pull back the second connector group 700 to increase or decrease the distance (or interval) G1 between the first connector group 600 and the second connector group 700. Figure 2A and Figure 2B ).

[0141] More specifically, the telescopic rod 900 includes a power unit 910 and a telescopic sleeve 920. The telescopic sleeve 920 includes at least two sleeve units 921, which are slidably overlapped together. These sleeve units 921 may be the same or different in size. These sleeve units 921 can be retracted to shorten the length of the telescopic sleeve 920. Figure 2A Conversely, these sleeve units 921 can be unfolded to increase the length of the telescopic sleeve 920. Figure 2B The first of these sleeve units 921 is fixed to the side of the first connector group 600 facing the second connector group 700. The last of these sleeve units 921 is fixed to the side of the second connector group 700 facing the first connector group 600. One end of the power unit 910 is fixed inside the first connector group 600, and the other end is connected to one of the sleeve units 921, enabling it to control the extension length of the telescopic sleeve 920, thereby moving the second connector group 700, wherein the major axis direction L1 of the first connector group 600 / second connector group 700 is orthogonal to the major axis direction L2 of the telescopic sleeve 920.

[0142] In this embodiment, the power unit 910 is, for example, a motor, a cylinder, or a solenoid valve; however, the present invention is not limited to the type of power unit 910.

[0143] Thus, when the power unit 910 linearly extends the telescopic sleeve 920 through its movable end, the telescopic sleeve 920 consequently pushes the second connector group 700 away from the first connector group 600, thereby increasing the distance G2 between the first connector group 600 and the second connector group 700; or, it pulls the second connector group 700 closer to the first connector group 600, thereby decreasing the distance G1 between the first connector group 600 and the second connector group 700. However, this invention is not limited to the type of telescopic rod 900.

[0144] However, this invention is not limited to this. In other embodiments, as long as it does not hinder the adjustment of the above-mentioned spacing, the power unit 910 may also be relocated to the second connector group 700; or / and the second connector group 700 may also be swapped with the first connector group 600, that is, the second connector group 700 may be relocated to the robotic arm 500.

[0145] Furthermore, the self-propelled liquid replenishment device 40 includes an image acquisition device 800, a robotic arm control device 410, and a control device 420. The image acquisition device 800 is disposed on the first connector group 600 and is used to acquire images of the liquid replenishment object and capture positioning images of the inlet and outlet ends. The robotic arm control device 410 is electrically connected to the robotic arm 500 and is used to control the robotic arm 500 to perform multi-axis movements. The control device 420 is disposed on the working body 100, between the first liquid tank 310 and the second liquid tank 320, and is electrically connected to the image acquisition device 800, the robotic arm control device 410, and the telescopic rod 900. The control device 420 can control the robotic arm control device 410 to control the movement of the robotic arm 500, and the robotic arm control device 410 can also be integrated into the control device 420, allowing the control device 420 to operate the movement of the robotic arm 500.

[0146] Thus, the control device 420 can analyze and locate the coordinate positions of the liquid replenishment object, the inlet end, and the outlet end within the positioning image, as well as the distance between the inlet end and the outlet end. Then, in response to the above information, it controls the robotic arm 500 to bring the first connector group 600 and the second connector group 700 closer to the inlet end and the outlet end, and controls the telescopic rod 900 to actuate, thereby adjusting the distance G1 between the first connector group 600 and the second connector group 700 so that the first connector group 600 is aligned with the inlet end and the second connector group 700 is aligned with the outlet end, thereby allowing the first connector group 600 to physically dock with the inlet end and the second connector group 700 to physically dock with the outlet end.

[0147] However, this invention is not limited to this. In other embodiments, as long as it does not hinder the imaging of the liquid replenishment object, the imaging device 800 may also be mounted on the robotic arm 500 or the second connector group 700.

[0148] Figure 3 for Figure 1 Side view of the first connector group 600. (See attached image) Figure 1 and Figure 3 As shown, the first connector assembly 600 includes a quick connector 610, a buffer chamber 640, and a centering device 650. The quick connector 610 is configured relative to the robotic arm 500 for docking with the inlet end. The buffer chamber 640 is sandwiched between the quick connector 610 and the centering device 650, and contains a cavity space 641 connecting the first pipeline assembly A1 and the quick connector 610.

[0149] Furthermore, the self-propelled fluid replenishment device 40 includes a pressure sensing device 660. The pressure sensing device 660 is connected to the centering device 650 on the side opposite the quick connector 610 and electrically connected to the control device 420, for sensing the pressure value applied to the quick connector 610. Thus, the control device 420 can control the robotic arm 500 to move the quick connector 610 of the first connector assembly 600 according to the pressure value received by the pressure sensing device 660, thereby assisting in the docking process between the first connector assembly 600 and the inlet end (not shown) of the fluid replenishment target.

[0150] Figure 4 for Figure 3 The diagram shows the operation of the centering device 650. Figure 3 and Figure 4 As shown, the centering device 650 includes a main body 651, a first plate 652, a second plate 653, and a plurality of (e.g., four) telescopic posts 654. The main body 651 is sandwiched between the first plate 652 and the buffer chamber 640, and locked to the first plate 652 and the buffer chamber 640. The front of the second plate 653 faces the first plate 652, and its back is fixed to the pressure sensing device 660. The second plate 653 includes a plurality of (e.g., four) through holes 653A. These through holes 653A are equidistantly distributed on the front of the second plate 653. More specifically, the front of the second plate 653 is circular. These through holes 653A represent different orientations of this front (e.g., 3, 6, 9, and 12 o'clock). The telescopic posts 654 are equidistantly distributed between the first plate 652 and the second plate 653. One end of each telescopic post 654 is fixed to the first plate 652, and the other end can slide through one of the through holes 653A and abut against a portion of the pressure sensing device 660. Therefore, the pressure sensing device 660 senses the pressure value of the first plate 652 under pressure in a specific orientation by the amount of pressure from one of the telescopic posts 654.

[0151] Thus, the control device 420 can control the robotic arm 500 to move the quick connector 610 of the first connector group 600 according to the pressure value in different directions, so that the quick connector 610 of the first connector group 600 can be more positively connected to the inlet end (not shown in the figure) of the liquid replenishment object.

[0152] Figure 5 for Figure 3 A longitudinal sectional view of the quick connector 610. (See attached image.) Figure 3 and Figure 5 As shown, the quick connector 610 includes a connector unit 620, a sleeve 630, and a spring element 633. The sleeve 630 includes a cylindrical body 631, a through hole 632H, and a through groove 632. One end of the cylindrical body 631 is connected to one end of the buffer chamber 640. The through groove 632 is formed through the cylindrical body 631, and the long axis L1 of the through groove 632 is parallel to the long axis L1 of the quick connector 610. The through hole 632H penetrates the bottom 632A of the through groove 632, and the diameter of the through hole 632H is smaller than the diameter of the through groove 632. The connector unit 620 extends partially into the through groove 632, the through hole 632H, and the chamber space 641, and is connected to the first pipeline group A1 through the chamber space 641. Figure 3 The spring element 633 is located in the through groove 632, surrounds the connector unit 620, and elastically abuts against the connector unit 620 and the bottom 632A of the through groove 632, respectively.

[0153] The connector unit 620 is a straight tube, comprising a front section 621, a middle section 622, a rear section 623, and a straight channel 624. The middle section 622 is located between the front section 621 and the rear section 623, and connects the front section 621 and the rear section 623. A portion of the middle section 622 extends into the through groove 632 and connects to the rear section 623 within the through groove 632; the other portion is located outside the through groove 632 and connects to the front section 621, which is used to connect to the inlet end (not shown) of the liquid replenishment object. A gap P exists between the outer wall of the middle section 622 and the inner wall of the cylinder 631. The rear section 623 is located within the chamber space 641 of the buffer chamber 640. The straight channel 624 sequentially passes through the front section 621, the middle section 622, and the rear section 623, and connects to the first pipeline group A1 through the chamber space 641. Figure 3 The spring element 633 includes a retaining ring 633A and a spring body 633B. The spring body 633B surrounds the intermediate section 622, and one end of the spring body 633B elastically abuts against the bottom 632A of the through groove 632, while the other end is fixedly connected to the retaining ring 633A. The retaining ring 633A abuts against the intermediate section 622 on one side opposite to the spring body 633B.

[0154] like Figure 5As shown, the middle section 622 is divided into three regions: left, middle, and right, with their pipe diameters decreasing from left region 622A > right region 622B > middle region 622C. The abutment ring 633A is located in the middle region 622C. The middle region 622C has a grooved ring 622C1. The grooved ring 622C1 has a bottom 622CB and two opposing first sidewalls 622CL and 622CR. The height of the first sidewall 622CL is greater than the height of the second sidewall 622CR. The first sidewall 622CL connects to the left region 622A, and the second sidewall 622CR connects to the right region 622B. The abutment ring 633A abuts against the first sidewall 622CL on the side opposite to the spring body 633B, and there is a first buffer space S1 between it and the bottom 622CB of the grooved ring 622C1. A second buffer space S2 exists between the right region 622B and the through hole 632H. Therefore, when the quick connector 610 has an alignment error at the liquid inlet end of the liquid-collecting object, the alignment error is corrected by the movement of the intermediate section 622 within the first buffer space S1 and the second buffer space S2. Specifically, when the alignment error (e.g., 3 mm) of the front section 621 of the quick connector 610 at the liquid inlet end of the liquid-collecting object is less than the movement value (e.g., 3.5 mm) of the intermediate section 622 within the first buffer space S1 and the second buffer space S2, the robotic arm 500 controls the quick connector 610 to continue moving towards the liquid inlet end of the liquid-collecting object, thereby automatically correcting the alignment error and completing the docking.

[0155] Thus, as Figure 1 and Figure 5 When the robotic arm 500 attempts to dock the connector unit 620 of the first connector group 600 to the inlet end (not shown) of the liquid replenishment object, even if there is an error between the connector unit 620 and the inlet end, the connector unit 620 can be slightly offset within the through groove 632 through the linkage of the spring element 633, thereby completing the docking with the inlet end.

[0156] Furthermore, the self-propelled fluid replenishment device 40 includes a hydraulic sensor 670. The hydraulic sensor 670 is located on the first pipeline assembly A1 and electrically connected to the control device 420, used to sense the hydraulic feedback value within the first pipeline assembly A1. Therefore, when the first connector assembly 600 begins replenishing the fluid to the target, if the control device 420 determines, based on the hydraulic feedback value within the first pipeline assembly A1, that the hydraulic feedback value within the target has not reached a preset standard, it indicates that the fluid in the target is not yet fully replenished. The control device 420 then controls the amount of fluid added to the target according to the hydraulic feedback value. However, this invention is not limited to this; in other embodiments, the hydraulic sensor may be omitted.

[0157] It should be understood that the first connector group 600 and the second connector group 700 in this embodiment are structurally identical or at least substantially identical to each other. Therefore, the features of the second connector group 700 are described above and will not be repeated here.

[0158] Figure 6 for Figure 1 A partial top view of the self-propelled fluid replenishment device 40. (See attached image.) Figure 1 and Figure 6 As shown, the self-propelled replenishment device 40 further includes a first electric pump 380, a second electric pump 390, a test container 340, and a filter 330. The first electric pump 380, the second electric pump 390, the test container 340, and the filter 330 are respectively disposed on the placement surface 110 of the working body 100. The first electric pump 380 is used to pressurize the liquid to be replenished in the first liquid tank 310 and inject it into the filter 330. The second electric pump 390 is used to evacuate the second liquid tank 320, thereby allowing the second connector assembly 700 to recover liquid from the replenishment target. The filter 330 is used to filter the liquid to be replenished and inject it into the replenishment target. The test container 340 has a liquid tank 350, which holds a small amount of liquid recovered from the replenishment target. Furthermore, the first liquid tank 310 and the second liquid tank 320 are further equipped with a level gauge 370. Figure 1 This allows us to determine the liquid level in the first liquid tank 310 and the second liquid tank 320.

[0159] Furthermore, in this embodiment, the robotic arm control device 410 is located between the first electric pump 380 and the first liquid tank 310, and between the second electric pump 390 and the second liquid tank 320. The filter 330 and the inspection container 340 are placed on the robotic arm control device 410; however, the present invention is not limited thereto.

[0160] A front pipeline A11 (e.g., a flexible hose) of the first pipeline group A1 is connected to the filter 330 and the first connector group 600. A first rear pipeline A12 (e.g., a flexible hose) of the first pipeline group A1 is connected to the filter 330 and the first liquid tank 310. A second rear pipeline A13 (e.g., a flexible hose) of the first pipeline group A1 is connected to the first electric pump 380 and the first liquid tank 310. A front pipeline A21 (e.g., a flexible hose) of the second pipeline group A2 is connected to the liquid tank 350 and the second connector group 700. A first rear pipeline A22 (e.g., a flexible hose) of the second pipeline group A2 is connected to the second electric pump 390 and the second liquid tank 320. A second rear pipeline A23 (e.g., a flexible hose) of the second pipeline group A2 is connected to the liquid tank 350 and the second liquid tank 320.

[0161] The control device 420 is electrically connected to the first electric pump 380 and the second electric pump 390, and is used to control the first electric pump 380 to perform a fluid replenishment operation on the fluid replenishment object in response to the hydraulic feedback value of the hydraulic sensor 670, and to control the second electric pump 390 to extract liquid from the fluid replenishment object.

[0162] Furthermore, the testing container 340 is equipped with multiple liquid quality testing units 360, which are connected to the liquid tank 350 for testing the liquid within the tank 350. For example, these liquid quality testing units 360 may be copper ion meters, pH meters, and turbidity meters, but the present invention is not limited to these.

[0163] Finally, for protection purposes, an outer cover C can be placed on the placement surface 110 of the working body 100 so that the first liquid tank 310, the second liquid tank 320, the control device 420, the robotic arm control device 410, the filter 330, the inspection container 340, the liquid quality inspection unit 360, the first electric pump 380 and the second electric pump 390 can be contained within it.

[0164] Figure 7 This is a block diagram of a fluid replenishment system 1 according to an embodiment of the present invention. Figure 8 This is a perspective view of the server device 20 of the fluid replenishment system 1 in this embodiment. Figure 9 This is a diagram illustrating the operation of the server device 20 and the self-propelled liquid replenishment device 40 in this embodiment.

[0165] like Figures 7 to 9 As shown, the replenishment system 1 includes a central control unit 10, multiple server devices 20, multiple docking stations 30, and multiple self-propelled replenishment devices 40. Each server device 20 includes a cabinet 21 and at least one cooling distribution unit 25. The cabinet 21 is, for example, a combination of a base plate 21A and a side column 21B. The cooling distribution unit 25 has a housing 26, a cooling channel 27, a liquid inlet connector 28, and a liquid outlet connector 29. The housing 26 is placed inside the cabinet 21. The liquid inlet connector 28 and the liquid outlet connector 29 are respectively arranged on one side of the housing 26, and the cooling channel 27 is located inside the housing 26, connecting the liquid inlet connector 28 and the liquid outlet connector 29 respectively. The cooling channel 27 can be a pipeline, a water tank, or a heat exchange chamber, etc.

[0166] In addition, each server device 20 includes a hydraulic sensing unit 23. The hydraulic sensing unit 23 is located in the cooling channel 27 and is used to sense the hydraulic feedback value in the cooling channel 27. Therefore, when the cooling distribution unit 25 determines that the hydraulic feedback value has not reached a preset standard, the cooling distribution unit 25 sends a fluid replenishment notification to the central control device 10.

[0167] Figure 10 This is a diagram illustrating the operation of the self-propelled liquid replenishment device 40 and the docking station 30 in this embodiment. Figure 7 and Figure 10 As shown, each docking station 30 is for the self-propelled liquid replenishment device 40 to dock and charge. More specifically, each docking station 30 includes a housing 31 and a charging module 32. The housing 31 has a docking surface 31A. The charging module 32 is located inside the housing 31 and has power supply contacts 33 exposed on the docking surface 31A.

[0168] like Figure 9 and Figure 10 As shown, the self-propelled liquid replenishment device 40 further includes a battery module 430 and at least one charging contact 431. The battery module 430 is disposed within the working body 100, while the charging contact 431 is exposed outside the working body 100. Thus, when the self-propelled liquid replenishment device 40 docks at the docking surface 31A of the docking station 30, the charging contact 431 of the self-propelled liquid replenishment device 40 can be disconnected from the power supply contact 33 of the docking station 30, thereby allowing the charging module 32 to charge the battery module 430.

[0169] In addition, such as Figure 10 As shown, each docking station 30 allows the self-propelled replenishment device 40 to exchange coolant. More specifically, each docking station 30 includes a replenishment tank 34, a waste liquid tank 35, a drain connector 36, and an inlet connector 37. The replenishment tank 34, located inside the housing 31, is used to hold the liquid to be replenished (such as coolant). The waste liquid tank 35, located inside the housing 31, is used to hold the recovered liquid (such as waste liquid) returned by the self-propelled replenishment device 40. The drain connector 36 is located on the docking surface 31A and connects to the replenishment tank 34. The inlet connector 37 is parallel to the drain connector 36 and connects to the waste liquid tank 35. Both the replenishment tank 34 and the waste liquid tank 35 have level gauges (not shown) that reflect the liquid level. Thus, when the self-propelled replenishment device 40 moves to the docking station 30, the first connector group 600 can be connected to the drain connector 36, and the second connector group 700 can be connected to the inlet connector 37, thereby receiving liquid addition and drainage from the docking station 30 respectively. More specifically, through the connection of the drain connector 36 and the first connector group 600, the liquid in the replenishment tank 34 will be added to the first liquid tank 310, and through the connection of the inlet connector 37 and the second connector group 700, the waste liquid in the second liquid tank 320 will be drained to the waste liquid tank 35.

[0170] like Figures 7 to 9 As shown, the central control device 10 is connected to the self-propelled replenishing devices 40, the docking station 30, and the server device 20 via a network architecture N. The central control device 10 is used to receive feedback signals from any server device 20 (such as replenishment notifications or hydraulic feedback values ​​from the hydraulic sensing unit 23), detect the position, task progress, and idle status of the self-propelled replenishing device 40, send control signals (such as assignment commands) to the self-propelled replenishing device 40, and monitor the liquid level in the replenishment tank 34 and waste tank 35 of the docking station 30.

[0171] For example, when the central control device 10 receives a replenishment notification from one of the server devices 20, the central control device 10 (1) assigns one of the self-propelled replenishment devices 40 to replenish the cooling distribution unit 25 of the server device 20, (2) provides a suitable movement route so that the self-propelled replenishment device 40 can move to the server device 20 as soon as possible, and (3) in accordance with the above hydraulic feedback value, instructs the self-propelled replenishment device 40 to replenish the cooling distribution unit 25 according to the corresponding replenishment amount.

[0172] Before replenishing the liquid, the self-propelled replenishment device 40, which is moved to the server device 20, can detect the position and distance between the liquid inlet connector 28 and the liquid outlet connector 29 through the image fed back by the image acquisition device 800, and correspondingly control the extension length of the telescopic rod 900 so that the distance between the first connector group 600 and the second connector group 700 matches (e.g., equal or approximately equal) the distance between the liquid inlet connector 28 and the liquid outlet connector 29. At the same time, it controls the movement of the robotic arm 500 so that the first connector group 600 can be removably connected to the liquid inlet connector 28 and the second connector group 700 can be removably connected to the liquid outlet connector 29. During the initial docking, based on the pressure value fed back by the pressure sensing device 660, the self-propelled liquid replenishment device 40 can determine whether the first connector group 600 and the liquid inlet connector 28 are docked properly, and whether the second connector group 700 and the liquid outlet connector 29 are docked properly. If they are not docked properly, the robotic arm 500 and / or the telescopic rod 900 are controlled to move towards the correct docking position based on the fed-back pressure value.

[0173] Next, a small amount of coolant from the cooling distribution unit 25 (hereinafter referred to as the recovered liquid) is recovered, and the pH value, copper ion content, turbidity, etc., of the recovered liquid are tested to ensure compliance. After the recovered liquid from the cooling distribution unit 25 is found to be compliant, the self-propelled replenishment device 40 will only replenish the cooling distribution unit 25 according to the aforementioned replenishment amount, without separately draining the recovered liquid; otherwise, the steps of draining the recovered liquid and filling the cooling distribution unit 25 with coolant will be performed simultaneously.

[0174] Finally, after completing its mission, the self-propelled replenishment unit 40 returns to its designated docking station 30 to perform charging and fluid exchange operations.

[0175] Furthermore, such as Figure 1 and Figure 8As shown, each server device 20 further includes a first signal transmitter 24. The first signal transmitter 24 is disposed on the cooling distribution unit 25 and is used to intermittently emit a first position signal. Each docking station 30 includes a second signal transmitter 38. The second signal transmitter 38 is disposed on the housing 31 and is used to intermittently emit a second position signal. The self-propelled liquid replenishment device 40 further includes a signal receiver 432, which is disposed on the working body 100 and is used to receive the first position signal to reach the corresponding server device 20, or to receive the second position signal to reach the corresponding docking station 30. Therefore, by sensing the second position signal through the signal receiver 432, the self-propelled liquid replenishment device 40 can dock at the docking surface 31A of the docking station 30 to perform the above-mentioned charging operation and liquid exchange operation.

[0176] It should be understood that in this embodiment, the quick connector 610 of the first connector group 600 and the liquid inlet connector 28 of the server device 20 are structurally complementary, for example, the complementary design of male and female connectors. Similarly, the quick connector 610 of the second connector group 700 and the liquid outlet connector 29 of the server device 20 are also structurally complementary, for example, the complementary design of male and female connectors. Furthermore, each self-propelled liquid replenishment device 40 in this embodiment is the same as the self-propelled liquid replenishment device 40 in the above embodiments. Therefore, the features of the self-propelled liquid replenishment device 40 are described above and will not be repeated here.

[0177] Figure 11 This is a flowchart of a fluid replenishment method according to an embodiment of the present invention. Figure 11 As shown, the liquid replenishment method of this embodiment includes steps 1101 to 1106, as follows: In step 1101, a self-propelled liquid replenishment device is assigned to the cooling distribution unit of a server device. In step 1102, the first connector group and the second connector group of the self-propelled liquid replenishment device are respectively aligned with the liquid inlet connector and the liquid outlet connector of the cooling distribution unit. In step 1103, the first connector group is connected to the liquid inlet connector, and the second connector group is connected to the liquid outlet connector. In step 1104, a portion of the liquid is extracted, and the liquid is checked for compliance. If yes, proceed to step 1105; otherwise, proceed to step 1106. In step 1105, the remaining volume of new liquid is injected into the cooling distribution unit through the liquid inlet connector. In step 1106, the cooling distribution unit is filled with new liquid, and the remaining portion of the old liquid is extracted.

[0178] Furthermore, step 1101 includes the following detailed steps: Determine whether the hydraulic feedback value in the cooling distribution unit has not reached a preset standard; if so, then dispatch a self-propelled fluid replenishment device to this cooling distribution unit.

[0179] Step 1102 further includes the following detailed steps: Imaging the cooling distribution unit and capturing positioning images of the inlet and outlet connectors; then, adjusting the distance between the first connector group and the second connector group according to the positioning images, so that the first connector group is coaxially aligned with the inlet connector, and the second connector group is coaxially aligned with the outlet connector. More specifically, a robotic arm moves the first and second connector groups to the front of the inlet and outlet connectors of the cooling distribution unit, and then adjusts the distance between the first and second connector groups using a telescopic rod, thereby achieving coaxial alignment of the first connector group with the inlet connector and coaxial alignment of the second connector group with the outlet connector.

[0180] Step 1103 further includes the following detailed steps: Detect the pressure values ​​of the first connector group and the second connector group when they are pressed. When the pressure values ​​meet the preset standard, it is determined that the first connector group and the inlet connector are properly connected, and the second connector group and the outlet connector are properly connected; otherwise, the orientation is adjusted by the robotic arm and / or telescopic rod of the self-propelled liquid replenishment device until the pressure values ​​of the first connector group and the second connector group meet the preset standard.

[0181] Step 1104 further includes the following detailed steps: The liquid is tested for copper ions, pH, and turbidity.

[0182] In step 1105, since the liquid in the cooling distribution unit is compliant, the self-propelled replenishment device only needs to inject new liquid to the remaining capacity of the cooling distribution unit. Thus, step 1105 further includes the following detailed steps: The self-propelled replenishment device determines whether the hydraulic pressure of the new liquid in the cooling distribution unit meets a preset standard. If yes, it stops injecting new liquid into the cooling distribution unit; otherwise, it continues injecting new liquid until the hydraulic pressure of the new liquid meets the preset standard. Then, it disconnects the first connector assembly from the inlet connector and the second connector assembly from the outlet connector.

[0183] More specifically, the hydraulic sensing unit within the cooling distribution unit senses the hydraulic pressure in the cooling channels and feeds this pressure back to the self-propelled replenishment device to determine whether to continue injecting new fluid or stop injecting new fluid into the cooling distribution unit. Alternatively, the self-propelled replenishment device determines whether to continue injecting new fluid or stop injecting new fluid into the cooling distribution unit based on the hydraulic pressure sensed by its hydraulic sensor in the first pipeline group connected to the first connector group.

[0184] In step 1106, since the liquid in the cooling distribution unit is not compliant, the self-propelled liquid replenishment device needs to over-inject new liquid into the cooling distribution unit until all the remaining liquid in the cooling distribution unit is discharged; then, the extracted liquid is inspected. If the inspected liquid is qualified, the first connector group is disconnected from the liquid inlet connector and the second connector group is disconnected from the liquid outlet connector; otherwise, new liquid is injected until the liquid is qualified.

[0185] Thus, through the architecture described in the above embodiments, the liquid replenishment system and self-propelled liquid replenishment device of this disclosure can dynamically adjust the distance between the first connector group and the second connector group to connect to the liquid inlet and liquid outlet of cooling distribution units of different specifications, thereby improving the service range of the self-propelled liquid replenishment device and the flexibility of the self-propelled liquid replenishment device in conjunction with various servo devices.

[0186] Finally, the embodiments disclosed above are not intended to limit the present invention. Any person skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention, and all such modifications and refinements will be protected under the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
