Description

Technical Field

[0001] The present invention relates to the technical field of servers, and in particular to a limiting device for an air cooling module. Background Art

[0002] In the related art, when testing the air cooling module of a server, since the sizes of the air cooling modules are different, the conventional limiting device is not compatible with air cooling modules of different sizes. Therefore, the operator usually presses the air cooling module with his hand, or uses other surrounding materials to squeeze the server, thereby limiting the air cooling module and completing the test operation of the air cooling module.

[0003] However, such a test has the disadvantages of being easily loosely clamped, high labor intensity for the operator, and easily scratching the operator's hands. Summary of the invention

[0004] In view of this, the present invention provides a limiting device for an air cooling module to solve the problems in the related art that the air cooling module is easily loosely clamped during testing, the labor intensity of the operator is high, and the operator's hands are easily scratched.

[0005] In a first aspect, the present invention provides a limiting device for an air cooling module, comprising:

[0006] Pedestal;

[0007] A first guide rail is provided on the base;

[0008] A first clamping portion is disposed on the base;

[0009] A second clamping portion is spaced apart from the first clamping portion along the length direction of the first guide rail and is slidably connected to the first guide rail;

[0010] The transmission mechanism is arranged on the base and connected with the second clamping part;

[0011] The driving mechanism, under the action of which, the transmission mechanism can drive the second clamping part to move along the first guide rail;

[0012] The operating assembly can drive the transmission mechanism under the action of an external force, so that the transmission mechanism drives the second clamping part to move along the first guide rail;

[0013] The switching mechanism connects the driving mechanism and the operating component, and has an automatic state and a manual state. The switching mechanism can connect the power output end of the driving mechanism with the transmission mechanism in the automatic state, and separate the operating component from the transmission mechanism, and separate the power output end of the driving mechanism with the transmission mechanism in the manual state, and connect the operating component to the transmission mechanism.

[0014] Beneficial effect: During use of the limiting device for the air-cooling module of the embodiment of the present invention, the air-cooling module can be arranged between the first clamping part and the second clamping part, and clamped and limited by the first clamping part and the second clamping part. When the volume of the air-cooling module is large or small, the adjustment mechanism can be switched to a manual state, thereby providing a flexible adjustment space, thereby ensuring reliable clamping for air-cooling modules of different sizes, and avoiding the risk of loose clamping during the test, which may cause the air-cooling module to be unstable or even overturned.

[0015] When the test task of the air-cooled module is heavy, the automation function can greatly improve production efficiency, reduce manual intervention, shorten the production cycle, and thus reduce the labor intensity of the operator and avoid scratching the operator's hands.

[0016] Therefore, the limiting device for the air cooling module in the embodiment of the present invention can ensure that the air cooling module is reliably clamped during the testing of the air cooling module, reduce the labor intensity of the operator, and avoid scratches on the operator's hands during the testing process.

[0017] In an optional implementation, the switching mechanism includes:

[0018] A sliding block is slidably disposed on the base, a sliding direction of the sliding block forms an angle with an extending direction of the first guide rail, and a driving mechanism and a manipulation assembly are disposed on the sliding block and spaced apart along the sliding direction of the sliding block;

[0019] The driving part is connected to the sliding block and can drive the sliding block to slide relative to the base.

[0020] Beneficial effect: Through such an arrangement, the operator can connect the power output end of the driving mechanism or the operating component with the transmission mechanism by adjusting the position of the sliding block during the test.

[0021] In an optional embodiment, a clearance opening is formed on the top wall of the base, the sliding block is arranged in the clearance opening, threaded holes are arranged on the side walls of the clearance opening along the length direction of the sliding block, and the driving part includes at least one screw rod, which passes through the threaded hole and the sliding block and is threadedly connected to the threaded hole;

[0022] The transmission mechanism includes a lead screw and a first bevel gear; the lead screw is arranged on the base and extends along the length direction of the first guide rail, and the nut of the lead screw is connected to the second clamping part; the first bevel gear is sleeved at one end of the lead screw;

[0023] The driving mechanism and the operating assembly can output rotational motion, and the power output ends of the driving mechanism and the operating assembly are arranged opposite to each other and are respectively sleeved with a second bevel gear and a third bevel gear. In the automatic state, the second bevel gear is meshed with the first bevel gear, and in the manual state, the third bevel gear is meshed with the first bevel gear.

[0024] The driving mechanism comprises a rotation source, the rotation source is arranged on the sliding block, and the second bevel gear is sleeved on the rotating shaft of the rotation source;

[0025] The operating assembly comprises a driving rod and a hand wheel. The driving rod is hinged on the base and extends along the sliding direction of the sliding block. The third bevel gear is sleeved on the driving rod. The hand wheel is sleeved on the driving rod outside the base.

[0026] Beneficial effect: Through such a configuration, the operator can drive the sliding block to move by rotating the screw, thereby carrying the driving mechanism and the operating assembly to move, wherein the distance between the second bevel gear and the third bevel gear is greater than the width of the first bevel gear, so when the second bevel gear is engaged with the first bevel gear, the third bevel gear can be separated from the first bevel gear, and when the second bevel gear is separated from the first bevel gear, the third bevel gear can be engaged with the first bevel gear.

[0027] Arranging the rotating shaft of the driving mechanism and the driving rod of the operating assembly to be relatively arranged can save the space occupied by the driving mechanism and the operating assembly along the length direction of the first guide rail, thereby making the structure of the limiting device more compact.

[0028] On this basis, when the adjustment mechanism is in the automatic state, the operator can adjust the position of the second clamping part steplessly by rotating the hand wheel, and the second clamping part can stop at the current position at any time to realize the clamping function. When the adjustment component is in the automatic state, the controller can obtain the torque of the rotation source in real time, and control the rotation source to stop rotating when the torque is greater than the preset value, thereby realizing the automatic clamping of air-cooled modules of different sizes, and ensuring that the limit device is compatible with air-cooled modules of different sizes.

[0029] In an optional embodiment, an external thread is formed on the outer circumference of the lead screw, and the thread lead angle of the external thread is smaller than the equivalent friction angle of the external thread.

[0030] Beneficial effects:

[0031] Through such a setting, not only the transmission efficiency of the screw can be improved, but also the screw can have a self-locking function. Its self-locking principle mainly relies on its thread lead angle being smaller than the equivalent friction angle. When the thread lead angle is smaller than the equivalent friction angle, the friction between the nut and the screw is sufficient to prevent the rotation of the nut, so that the nut can only move along the axial direction of the screw and cannot rotate on its own. That is, in the current scenario application, the second clamping part is driven to move along the first guide rail by driving the operating assembly, and the self-locking characteristics of its structural design can prevent the second clamping part from moving on its own after adjustment, thereby maintaining the stability of the mechanism and avoiding the shaking or displacement of the air-cooled module due to vibration during the test, which can ensure the safety of the operator.

[0032] In an optional embodiment, the cross-section of the external thread along the axial direction of the lead screw is a trapezoid, and the angle between the opposite surfaces of two adjacent trapezoids is 30°.

[0033] In an optional embodiment, the limiting device further includes:

[0034] The first side plate and the second side plate are arranged on the base at intervals, and the first guide rail is arranged on the opposite surfaces of the first side plate and the second side plate; and / or;

[0035] A first guide rail is arranged on the top surface of the base.

[0036] Beneficial effects:

[0037] Through such an arrangement, the first side plate, the second side plate, the first clamping part and the second clamping part can be used to form a receiving groove for accommodating the air cooling module. When the first guide rails are respectively provided on the top surfaces of the first side plate, the second side plate and the base, the first guide rails can limit the second clamping part from the three side edges of the second clamping part. The first side plate, the second side plate and the base can jointly provide three-sided guiding support for the second clamping part through the first guide rails. When the second clamping part tends to deviate left and right during the forward and backward movement, complementary torsional and tensile forces can be formed under the action of the first side plate and the second side plate, thereby offsetting the overall deformation of the second clamping part and possible movement jamming.

[0038] In an optional embodiment, the first side plate, the second side plate, the first clamping portion and the second clamping portion can enclose a receiving groove for receiving the air cooling module, and the limiting device further includes a clamping assembly, and the clamping assembly includes:

[0039] A base portion, detachably connected to the upper side of the receiving groove;

[0040] an elastic member connected to the base;

[0041] The pressing plate is used to be arranged in the accommodating groove and connected to the elastic member.

[0042] Beneficial effects:

[0043] After the air-cooling module is placed into the receiving groove, the clamping assembly can be placed above the air-cooling module, and the elastic member can drive the pressing plate to clamp materials of different height sizes, which not only improves the compatibility of the limiting device in the height direction, but also prevents the operator's hand from reaching in from above and causing damage.

[0044] In an optional embodiment, the base is further provided with a label pasting assembly, including:

[0045] The main body is arranged on the base;

[0046] A label slot, provided on one side of the main body, for accommodating a label;

[0047] A clamping groove, provided in the label groove, for accommodating a cold pipe or a cable;

[0048] The wire end limiting groove is arranged on the main body and is spaced apart from the clamping groove to accommodate the wire end of the cable.

[0049] Beneficial effect: Through such a setting, the operator can affix labels to the cooling pipes, cables, etc. of the air-cooling module when the air-cooling module is being tested. After starting the test program, the operator can first take out the label, place it in the label slot, and make the glued side of the label face outward. At this time, the clamping slot is located on the side of the label close to the bottom of the slot, and then put the cable end to be pasted into the cable end limiting slot, and press the cable into the clamping slot through the label, and then put the finger into the un-glueized side of the label, wrap the label on the cable, and complete the labeling.

[0050] On this basis, the label pasting assembly can also control the distance between the label and the cable end through the cooperation between the label slot and the cable end limit slot, so as to ensure standardized pasting at a uniform position of the cold pipe or cable. Therefore, the label pasting assembly of the embodiment of the present application can effectively improve the accuracy of the label pasting position and the overall pasting efficiency.

[0051] In an optional embodiment, a second guide rail is provided on the main body, and the second guide rail extends along the distance direction between the label slot and the thread end limiting slot, and the label pasting assembly further includes:

[0052] The movable block is slidably connected with the second guide rail, and the label slot and the clamping slot are formed on the movable block.

[0053] Beneficial effect: For cold pipes and cables of different models and specifications, the positions where labels need to be pasted are different. The operator can drive the label slot to move along the second guide rail, and then adjust the distance between the label slot and the wire end limiting slot, so that the label pasting component can paste labels on cables and cold pipes of different models and specifications, and ensure standardized pasting at a uniform position on the cold pipe or cable.

[0054] In an optional embodiment, the top of the movable block is formed with:

[0055] An insertion port, connected to the label slot;

[0056] The first avoidance gap and the second avoidance gap are arranged in the label groove and communicate with the two side surfaces of the movable block. The first avoidance gap and the second avoidance gap are respectively arranged on the two sides of the clamping groove.

[0057] Beneficial effect: Through such a configuration, during use of the label pasting assembly of the embodiment of the present application, the operator can insert the label into the label slot through the insertion port, and the first avoidance gap and the second avoidance gap can allow the operator's fingers to be inserted, thereby facilitating the operator to insert his fingers into the un-glued side of the label, thereby facilitating the operator to paste the label.

[0058] In an optional embodiment, at least one temperature transmitting diaphragm is provided on the first clamping portion and / or the second clamping portion, and at least one temperature sensor is provided on the base; and / or,

[0059] A plurality of mounting openings are formed on the first clamping portion and / or the second clamping portion, and honeycomb ventilation plates are arranged in the mounting openings.

[0060] Beneficial effect: Through such an arrangement, the temperature sensor can be used to detect the temperature inside the containing tank, and the temperature transmitter diaphragm can convert the signal of the temperature sensor into a standard analog or digital signal, thereby forming a temperature monitoring area inside the containing tank, which can be centrally controlled by the temperature variable control board to effectively monitor the internal temperature of the containing tank.

[0061] The honeycomb air guide plate can discharge the temperature in the receiving tank to the greatest extent, thereby reducing the impact of the radiator itself on the ambient temperature.

[0062] In an optional embodiment, the limiting device further includes:

[0063] The cold plate groove is arranged on the base and is located at a side of the second clamping part away from the first clamping part, and is used to accommodate the cold plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0093] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0094] Combine the following Figures 1 to 15 , describing an embodiment of the present invention.

[0095] According to an embodiment of the present invention, on the one hand, a limiting device for an air-cooled module is provided, comprising a base 1, a first guide rail 2, a first clamping portion 3, a second clamping portion 4, a transmission mechanism 5, a driving mechanism 6, an operating assembly 7 and a switching mechanism 8. Among them, the first guide rail 2 is arranged on the base 1. The first clamping portion 3 is arranged on the base 1. The second clamping portion 4 is spaced apart from the first clamping portion 3 along the length direction of the first guide rail 2, and is slidably connected to the first guide rail 2. The transmission mechanism 5 is arranged on the base 1 and is connected to the second clamping portion 4. The transmission mechanism 5 can drive the second clamping portion 4 to move along the first guide rail 2 under the action of the driving mechanism 6. The operating assembly 7 can drive the transmission mechanism 5 under the action of an external force, so that the transmission mechanism 5 drives the second clamping portion 4 to move along the first guide rail 2. The switching mechanism 8 connects the driving mechanism 6 and the operating component 7, and has an automatic state and a manual state. The switching mechanism 8 can connect the power output end of the driving mechanism 6 with the transmission mechanism 5 and separate the operating component 7 from the transmission mechanism 5 in the automatic state, and separate the power output end of the driving mechanism 6 from the transmission mechanism 5 and connect the operating component 7 to the transmission mechanism 5 in the manual state.

[0096] During use of the limiting device for the air-cooling module of the embodiment of the present invention, the air-cooling module can be arranged between the first clamping portion 3 and the second clamping portion 4, and clamped and limited by the first clamping portion 3 and the second clamping portion 4. When the volume of the air-cooling module is large or small, the adjustment mechanism can be switched to a manual state, thereby providing a flexible adjustment space, thereby ensuring reliable clamping for air-cooling modules of different sizes, and avoiding the risk of loose clamping during testing, which may cause the air-cooling module to be unstable or even overturn.

[0097] When the test task of the air-cooled module is heavy, the automation function can greatly improve production efficiency, reduce manual intervention, shorten the production cycle, and thus reduce the labor intensity of the operator and avoid scratching the operator's hands.

[0098] Therefore, the limiting device for the air cooling module in the embodiment of the present invention can ensure that the air cooling module is reliably clamped during the testing of the air cooling module, reduce the labor intensity of the operator, and avoid scratches on the operator's hands during the testing process.

[0099] In one embodiment, the switching mechanism 8 includes a sliding block 801 and a driving unit 802. The sliding block 801 is slidably disposed on the base 1, and an angle is formed between the sliding direction of the sliding block 801 and the extension direction of the first guide rail 2. The driving mechanism 6 and the operating assembly 7 are disposed on the sliding block 801 and are spaced apart along the sliding direction of the sliding block 801. The driving unit 802 is connected to the sliding block 801 and can drive the sliding block 801 to slide relative to the base 1.

[0100] By such arrangement, during the test, the operator can connect the power output end of the driving mechanism 6 or the operating component 7 with the transmission mechanism 5 by adjusting the position of the sliding block 801 .

[0101] In one embodiment, a clearance opening is formed on the top wall of the base 1, the sliding block 801 is arranged in the clearance opening, threaded holes are arranged on the side walls of the clearance opening along the length direction of the sliding block 801, and the driving part 802 includes at least one screw rod, which passes through the threaded hole and the sliding block 801 and is threadedly connected with the threaded hole;

[0102] The transmission mechanism 5 includes a lead screw 501 and a first bevel gear 502; the lead screw 501 is disposed on the base 1 and extends along the length direction of the first guide rail 2, and the nut of the lead screw 501 is connected to the second clamping part 4; the first bevel gear 502 is sleeved at one end of the lead screw 501;

[0103] The driving mechanism 6 and the operating assembly 7 can output rotational motion, and the power output ends of the driving mechanism 6 and the operating assembly 7 are arranged opposite to each other and are respectively sleeved with a second bevel gear 602 and a third bevel gear 703. In the automatic state, the second bevel gear 602 is meshed with the first bevel gear 502, and in the manual state, the third bevel gear 703 is meshed with the first bevel gear 502;

[0104] The driving mechanism 6 comprises a rotation source 601, the rotation source 601 is arranged on the sliding block 801, and the second bevel gear 602 is sleeved on the rotating shaft of the rotation source 601;

[0105] The operating assembly 7 includes a driving rod 701 and a hand wheel 702 . The driving rod 701 is hinged on the base 1 and extends along the sliding direction of the sliding block 801 . The third bevel gear 703 is sleeved on the driving rod 701 . The hand wheel 702 is sleeved on the driving rod 701 outside the base 1 .

[0106] By such a configuration, the operator can drive the sliding block 801 to move by rotating the screw, thereby carrying the driving mechanism 6 and the operating assembly 7 to move, wherein the distance between the second bevel gear 602 and the third bevel gear 703 is greater than the width of the first bevel gear 502, so when the second bevel gear 602 is engaged with the first bevel gear 502, the third bevel gear 703 can be separated from the first bevel gear 502, and when the second bevel gear 602 is separated from the first bevel gear 502, the third bevel gear 703 can be engaged with the first bevel gear 502.

[0107] Arranging the rotating shaft of the driving mechanism 6 and the driving rod 701 of the operating assembly 7 to be relatively arranged can save the space occupied by the driving mechanism 6 and the operating assembly 7 along the length direction of the first guide rail 2, thereby making the structure of the limiting device more compact.

[0108] On this basis, when the adjustment mechanism is in the automatic state, the operator can adjust the position of the second clamping part 4 steplessly by rotating the hand wheel 702, and the second clamping part 4 can stop at the current position at any time, and realize the clamping function. When the adjustment component is in the automatic state, the controller can obtain the torque of the rotation source 601 in real time, and control the rotation source 601 to stop rotating when the torque is greater than the preset value, thereby realizing the automatic clamping of air-cooling modules of different sizes, and ensuring that the limit device is compatible with air-cooling modules of different sizes.

[0109] In one embodiment, a bearing 103 is formed on a side wall of the base 1 , and the lead screw 501 passes through the bearing 103 .

[0110] The rotation source 601 may be a device capable of outputting rotation, such as a motor, an engine, a hydraulic motor, or a combination of one of them and a reducer.

[0111] For example, in a preferred embodiment, Figure 4 As shown, the driving mechanism 6 includes a motor, a motor bracket, a coupling, a transmission shaft, a support seat, an adjustment pad, and a second bevel gear 602. The motor is arranged on the base 1 through the motor bracket, and the coupling is connected to the output shaft of the motor. The support seat is arranged on the base 1, one end of the transmission shaft is connected to the coupling, and the other end passes through the support seat and is connected to the second bevel gear 602.

[0112] In one embodiment, the sliding block 801 is a dovetail plate, a dovetail groove is formed on the side wall of the avoidance opening, and the dovetail bottom plate is stuck in the dovetail groove.

[0113] In the embodiments of the present application, there is no limitation on the number of screws. For example, in a preferred embodiment, there are two screws, which are spaced apart along the length direction of the first guide rail 2, and both ends of each screw pass through the side walls of the base 1 respectively. During use, the operator's two hands can hold a screw from each side of the base 1 and rotate the screws in opposite directions.

[0114] By configuring in this way, two screw rods are used to simultaneously drive the sliding block 801 , so that the movement of the sliding block 801 can be more stable, and the operator's hands can rotate the screw rods in opposite directions from both sides of the base 1 , which is in line with the user's usage habits.

[0115] As a convertible implementation, in an embodiment not shown in the drawings, the driving mechanism 6 and the operating assembly 7 may also be optionally extended along the length direction of the first guide rail 2, and spaced apart along the sliding direction of the sliding block 801. In this case, the lead screw 501 may be sleeved with a driven gear, and the power output ends of the driving mechanism 6 and the operating assembly 7 may be sleeved with a first driving gear and a second driving gear, respectively.

[0116] As another alternative embodiment, the operator may also choose to slide the sliding block 801 relative to the base 1 directly by hand.

[0117] In one embodiment, an external thread 5011 is formed on the outer circumference of the lead screw 501 , and a thread lead angle of the external thread 5011 is smaller than an equivalent friction angle of the external thread 5011 .

[0118] By such an arrangement, not only the transmission efficiency of the lead screw 501 can be improved, but also the lead screw 501 can have a specific self-locking function. Its self-locking principle mainly relies on its thread lead angle being smaller than the equivalent friction angle. When the thread lead angle is smaller than the equivalent friction angle, the friction force between the nut and the lead screw 501 is sufficient to prevent the rotation of the nut, so that the nut can only move axially along the lead screw 501 and cannot rotate on its own. That is, in the current scene application, the second clamping part 4 is driven to move along the first guide rail 2 by driving the operating component 7, and the self-locking characteristics of its structural design can prevent the second clamping part 4 from moving on its own after adjustment, thereby maintaining the stability of the mechanism and avoiding the air-cooled module from shaking or offsetting due to vibration during the test, which can ensure the safety of the operator.

[0119] In one embodiment, Fig.15 As shown, the cross section of the external thread 5011 along the axial direction of the lead screw 501 is a trapezoid, and the angle between the opposite surfaces of two adjacent trapezoids is 30°.

[0120] In one embodiment, Figure 3 As shown, the limiting device further includes a first side plate 9 and a second side plate 10. The first side plate 9 and the second side plate 10 are arranged on the base 1 at intervals, and a first guide rail 2 is arranged on the opposite surfaces of the first side plate 9 and the second side plate 10. The first guide rail 2 is arranged on the top surface of the base 1.

[0121] Through such an arrangement, the first side plate 9, the second side plate 10, the first clamping portion 3 and the second clamping portion 4 can be used to form a receiving groove for accommodating the air cooling module. When the first side plate 9, the second side plate 10 and the top surface of the base 1 are respectively provided with the first guide rail 2, the first guide rail 2 can limit the second clamping portion 4 from the three side edges of the second clamping portion 4. The first side plate 9, the second side plate 10 and the base 1 can jointly provide three-sided guiding support for the second clamping portion 4 through the first guide rail 2. When the second clamping portion 4 tends to deviate left and right during the forward and backward movement, torsional and tensile forces can be complementary under the action of the first side plate 9 and the second side plate 10, thereby offsetting the overall deformation of the second clamping portion 4 and the possible movement jamming.

[0122] In one embodiment, the first side plate 9, the second side plate 10, the first clamping portion 3 and the second clamping portion 4 can enclose a receiving groove for receiving the air cooling module, and the limiting device further includes a clamping assembly 11, and the clamping assembly 11 includes a base 1101, an elastic member 1102 and a pressing plate 1103. The base 1101 is detachably connected to the upper side of the receiving groove. The elastic member 1102 is connected to the base 1101. The pressing plate 1103 is used to be arranged in the receiving groove and connected to the elastic member 1102.

[0123] After the air-cooling module is placed into the receiving groove, the clamping assembly 11 can be placed above the air-cooling module, and the elastic member 1102 can drive the pressing plate 1103 to clamp materials of different height sizes, which can not only improve the compatibility of the limiting device in the height direction, but also prevent the operator's hand from reaching in from above and causing damage.

[0124] In one embodiment, the clamping assembly 11 further includes a locker 1104, a guide bearing 1105, a stop ring 1106 and a guide shaft 1107. The locker 1104 is disposed on the base 1101 and is used to connect the clamping assembly 11 to the first side plate 9 and the second side plate 10. The guide bearing 1105 is formed on the base 1101, the guide shaft 1107 passes through the guide bearing 1105, the elastic member 1102 is sleeved on the guide shaft 1107 and supported between the pressing plate 1103 and the base 1101, and the stop ring 1106 is sleeved on the guide shaft 1107 and is disposed at one end of the base 1101 away from the pressing plate 1103, so as to prevent the guide shaft 1107 from coming off the base 1 under the support of the elastic member 1102.

[0125] In one embodiment, Figure 1 and Figure 8 As shown, the base 1 is also provided with a label pasting assembly 12, including a main body 1201, a label slot 1202, a clamping slot 1203 and a thread end limiting slot 1204. The main body 1201 is provided on the base 1;

[0126] The label slot 1202 is provided on one side of the main body 1201 for accommodating a label. The clamping slot 1203 is provided in the label slot 1202 for accommodating a cold pipe or a cable. The wire end limiting slot 1204 is provided on the main body 1201 and is spaced apart from the clamping slot 1203 for accommodating a wire end of a cable.

[0127] Through such a setting, the operator can attach labels to the cooling pipes, cables, etc. of the air-cooling module when the air-cooling module is being tested. After starting the test program, the operator can first take out the label, place it in the label slot 1202, and make the glued side of the label face outward. At this time, the clamping slot 1203 is located on the side of the label close to the bottom of the label slot 1202, and then put the cable end to be attached into the cable end limiting slot 1204, and press the cable into the clamping slot 1203 through the label, and then put the finger into the un-glueized side of the label to wrap the label on the cable, so as to complete the labeling.

[0128] On this basis, the label pasting assembly 12 can also control the distance between the label and the cable end through the cooperation between the label slot 1202 and the thread end limiting slot 1204, so as to ensure standardized pasting at a uniform position of the cold pipe or cable. Therefore, the label pasting assembly 12 of the embodiment of the present application can effectively improve the accuracy of the label pasting position and the overall pasting efficiency.

[0129] In one embodiment, the main body 1201 is provided with a second guide rail 1209, which extends along the distance direction between the label slot 1202 and the thread end limiting slot 1204, and the label pasting assembly 12 further includes a movable block 1205. The movable block 1205 is slidably connected to the second guide rail 1209, and the label slot 1202 and the clamping slot 1203 are formed on the movable block 1205.

[0130] For cold pipes and cables of different models and specifications, the positions where labels need to be pasted are different. The operator can drive the label slot 1202 to move along the second guide rail 1209, and then adjust the distance between the label slot 1202 and the wire end limiting slot 1204, so that the label pasting component 12 can paste labels on cables and cold pipes of different models and specifications, and ensure that standardized pasting is completed at a uniform position on the cold pipe or cable.

[0131] In one embodiment, an insertion opening 1206, a first avoidance notch 1207, and a second avoidance notch 1208 are formed on the top of the movable block 1205. The insertion opening 1206 is connected to the label slot 1202. The first avoidance notch 1207 and the second avoidance notch 1208 are arranged in the label slot 1202 and communicate with the two side surfaces of the movable block 1205. The first avoidance notch 1207 and the second avoidance notch 1208 are respectively arranged on both sides of the clamping slot 1203.

[0132] Through such a configuration, during use of the label pasting component 12 of the embodiment of the present application, the operator can insert the label into the label slot 1202 through the insertion port 1206, and the first avoidance gap 1207 and the second avoidance gap 1208 can be used for the operator's fingers to be inserted, thereby facilitating the operator to insert his fingers to the un-glued side of the label, thereby facilitating the operator to paste the label.

[0133] In one embodiment, the first avoidance gap 1207 and the second avoidance gap 1208 are U-shaped gaps that can fit the operator's fingers.

[0134] As a convertible implementation, in an embodiment not shown in the accompanying drawings, the first avoidance gap 1207 and the second avoidance gap 1208 can also be selected as square grooves, arc grooves, etc., as long as the operator's fingers can be inserted into the un-glued side of the label.

[0135] In one embodiment, Figure 5 As shown, at least one temperature transmitting diaphragm 401 is provided on the first clamping portion 3 and / or the second clamping portion 4, and at least one temperature sensor 101 is provided on the base 1; and / or,

[0136] A plurality of mounting openings are formed on the first clamping portion 3 and / or the second clamping portion 4, and a honeycomb ventilation plate 301 is disposed in the mounting openings.

[0137] Through such an arrangement, the temperature sensor 101 can be used to detect the temperature inside the containing tank, and the temperature transmitter diaphragm 401 can convert the signal of the temperature sensor 101 into a standard analog or digital signal, thereby forming a temperature monitoring area inside the containing tank, and centralized calculation and control are performed by the temperature variable control board 106, so as to effectively monitor the internal temperature of the containing tank.

[0138] The honeycomb air guide plate can discharge the temperature in the receiving tank to the greatest extent, thereby reducing the impact of the radiator itself on the ambient temperature.

[0139] It should be noted that in the embodiment of the present application, there is no limitation on the number of temperature sensors 101 and temperature transmitter diaphragms 401. For example, in an optional embodiment, there are four temperature sensors 101, which are spaced apart along the length direction of the base 1, and there are three temperature transmitter modules, which are arranged on the second clamping portion 4.

[0140] In the embodiment of the present application, the material of the honeycomb ventilation plate 301 is not limited. For example, in a preferred embodiment, the honeycomb ventilation plate 301 is an aluminum honeycomb waveguide ventilation plate, which can not only ensure that the limiting device has good heat dissipation performance, but also reduce the noise during the test, and at the same time avoid the operator's fingers from accidentally intruding and causing damage to the operator's hands.

[0141] In one embodiment, Figure 6 As shown, the first clamping portion 3 and the honeycomb ventilation plate 301 are both designed with wire grooves, through which wires can pass and connect to the power module 110 and the signal board placed at the rear side.

[0142] In one embodiment, the limiting device further includes a cold plate groove 102. The cold plate groove 102 is provided on the base 1 and is located on a side of the second clamping portion 4 away from the first clamping portion 3, and is used to accommodate the cold plate.

[0143] Through such a configuration, the limiting device of the embodiment of the present application can not only limit the air cooling module, but also can be used to limit the cooling fan in the liquid cooling module. When the cooling fan of the liquid cooling module is arranged in the receiving groove, the cold plate of the liquid cooling module can be arranged in the cold plate groove 102.

[0144] In the embodiment of the present application, it should be noted that the number of the cold plate slots 102 is not limited. For example, in a preferred embodiment, there are two cold plate slots 102, which can meet the use requirements of most liquid cooling modules.

[0145] In one embodiment, Fig.10 As shown, the base 1 also includes a bottom plate, and a whole set of electric control components are arranged on the bottom plate of the base 1, and the electric control components include a PLC controller 105, a relay 107, a power module 110, a power interface 104, a temperature sensor 101 and a voltage conversion board 109. The PLC controller 105 can control the overall action logic of the limit device, and control the motor automation action through the relay 107. The power module 110 can transmit the power transmitted by the power interface 104 to each component and sensor respectively, and the voltage conversion board 109 can convert the voltage to the required size. The temperature change control board 106 can uniformly regulate the sensing temperature of the temperature sensor 101 and the temperature transmitter diaphragm 401.

[0146] In one embodiment, a signal adapter 108 is further disposed in the base 1 for converting signals between different types of interfaces to achieve communication and data exchange between devices.

[0147] In one embodiment, a front button panel is further provided on one side of the base 1. The front button panel is provided with start, reset and emergency stop buttons, which can facilitate employees to control the movement state of the limit device by pressing the buttons.

[0148] Next, the use process of the limiting device for the air cooling module according to the embodiment of the present invention is described:

[0149] 1. Place the cold plate of the liquid cooling module in the cold plate slot 102, place the air cooling module of the liquid cooling module between the first clamping part 3 and the second clamping part 4, take out the cables from the threading groove of the first clamping part 3 and connect them to the monitoring device, and place the cold pipe of the liquid cooling module on the label pasting assembly 12.

[0150] 2. Turn the handwheel 702 to make the handwheel 702 rotate on the support seat through the transmission shaft and drive the third bevel gear 703 at the end to rotate. The third bevel gear 703 is toothed with the first bevel gear 502, driving the screw 501 nut to rotate on the screw 501, converting the rotational motion into the linear motion of the second clamping part 4, thereby clamping the parts to be tested.

[0151] Similarly, if it is necessary to switch to automatic mode, it is only necessary to adjust the screws on both sides. Through the thrust of the screws, the dovetail plate is pushed to move in the dovetail groove on the avoidance opening of the base 1, causing the third bevel gear of the operating assembly 7 to disengage from the first bevel gear 502, and the second bevel gear 602 to be toothed with the first bevel gear 502. The operator can confirm the tooth connection position and gear meshing distance between the bevel gears based on the tightening force, and lock the stud on the other side.

[0152] When the switching mechanism 8 is in the automatic state, the operator can press the start button on the button panel, and the motor drives the coupling and the second bevel gear 602 to rotate, and then drives the sliding block 801 to move in the same way, and drives the second clamping part 4 to move, so as to clamp the component to be tested. The specific clamping degree is controlled according to the motor torque feedback, which can effectively avoid being too tight or too loose.

[0153] 3. Plug in the cable, connect the testing instrument, and start the testing program;

[0154] 4. During the test, the employee can place the cold pipe or cable in the label pasting component 12 from the side of the base 1, and use the label pasting component 12 to complete standardized pasting at a uniform position of the cold pipe or cable;

[0155] 5. During the test, the four temperature sensors 101 on the base 1 and the temperature transmitter diaphragm 401 embedded on the second clamping part 4 form a 7-point three-dimensional temperature monitoring area. The temperature control board 106 performs centralized calculation and control, which can effectively monitor the internal temperature of the receiving tank. At the same time, the honeycomb waveguide ventilation plate can discharge its own heat to the greatest extent, reducing the influence of the radiator itself on the ambient temperature.

[0156] 6. After the test is completed, wait for the internal components to stop running completely, unplug the detection end connector, reversely rotate the hand wheel 702 (click the reset button in the automatic state), the screw 501 reverses to drive the second clamping part 4 to move away from the first clamping part 3, take out the cold plate, fan and other components that have been tested, and the test is completed.

[0157] In summary, the limiting device for the air cooling module in the embodiment of the present application can ensure that the air cooling module is reliably clamped during the testing of the air cooling module, reduce the labor intensity of the operator, and avoid scratches on the operator's hands during the test.

[0158] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
