Description

Technical Field

[0001] The invention relates to the technical field of liquid cooling plate brazing welding devices, in particular to a liquid cooling plate processing welding device and a processing method. Background Art

[0002] Water cooling plate, liquid cooling plate, English called cold plate, translated as cold plate, translated as watercooling plate, many domestic translation into watercooling plate, or liquid cooling plate. It is a product component of water cooling radiator, a component that exchanges heat through liquid cooling. Its heat dissipation principle is to form flow channels in metal plates, electronic components are installed on the surface of the water cooling plate (heat-conducting medium is coated in the middle), and the internal coolant enters from the inlet of the plate and then takes away the outlet heat of the components from the outlet.

[0003] At present, the support structure used in the welding process of liquid cooling plates is single, and a fixed bracket is mostly used to support the welding head. In the actual processing process, due to the different weld structures of the welding workpieces, the direction of the welding head and the solder needs to be adjusted. Since the support structure of existing equipment is mostly fixed, it is difficult for operators to adjust the position of the welding head during operation, making the applicability of the equipment relatively single, resulting in difficulty in adjusting the equipment according to demand during the processing process.

[0004] For example, a welding device and a processing method for liquid cooling plate processing disclosed in China Invention Publication No. CN115890090A, the welding device is provided with a clamping mechanism. After the main body of the device is assembled, the catheter of the welding mechanism is placed above the connecting rod, and the positioning frame is pressed at the same time. The positioning frame squeezes the limit spring, and the limit spring is squeezed and deformed. The positioning frame loses the constraint of the limit spring and slides into the hollow block. Then the U-shaped frame is moved, and the U-shaped frame drives the protective gasket to buckle to the surface of the catheter. The U-shaped frame hits the surface of the hollow block during the rotation. When the U-shaped frame hits the surface of the hollow block, the positioning frame is released, the limit spring loses the pressure of the positioning frame and rebounds. The positioning frame is pushed to reset by the limit spring. The positioning frame is inserted into the U-shaped frame during the resetting process, and the position of the U-shaped frame is limited. Then the clamping operation of the catheter is completed. By providing the clamping mechanism, the device can limit the position of the catheter, thereby reducing the probability of winding of the device catheter and further improving the fluidity of the device catheter.

[0005] However, the above-mentioned device is intended to make corresponding adjustments to the welding head, and the welding method of the above-mentioned device is only applicable to spot welding, specifically, corresponding welding is performed on the surface of the liquid cooling plate. The liquid cooling plate is usually brazed in the actual welding process, and the welding process of the liquid cooling plate brazing is specifically to coat the cleaned liquid cooling plate with brazing flux, and assemble the liquid cooling plate to be welded according to the design requirements. After completing the above work, the liquid cooling plate needs to be sent to the brazing furnace for heating. The brazing temperature is generally controlled above the melting point of the brazing material and below the melting point of the base material. Therefore, the above-mentioned device is difficult to be compatible with the brazing of the liquid cooling plate. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a welding device and a processing method for a liquid cooling plate, which solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a welding device and a processing method for liquid cooling plate processing, comprising a processing seat for liquid cooling plate processing, characterized in that: the processing seat is divided into three partition stations, namely a transmission station, a guide station and a processing station, a transmission adsorption module is arranged at the transmission station, a guide coating module is arranged at the guide station, and a processing module is arranged at the processing station;

[0008] The guide coating module includes limiting grooves arranged at both sides of the guide station in the processing seat, and a clamping disk for guiding clamping is arranged in the limiting groove. A rotating leg whose other end is connected to the rotating shaft is welded on the top of the clamping disk, and the rotating leg is fixedly connected to the rotating shaft, and the rotating shaft is connected to the transmission gear through a connecting key; after the liquid cooling plate promoted and transmitted by the transmission station in the processing seat passes through the clamping disk, there is a movement conflict between the side walls, so the clamping disk is subjected to an outward driving force, and at this time the clamping disk and the rotating legs connected thereto are expanded outwardly, and after expanding until the clamping disk contacts the side wall of the liquid cooling plate, the liquid cooling plate is smoothly advanced and is always limited by the clamping disks on both sides, thereby ensuring the stable guidance of the liquid cooling plate during the welding transmission process;

[0009] Furthermore, when the liquid cooling plate is brazed, it is necessary to coat the liquid cooling plate with brazing flux. In view of this situation, a method for coating the side wall of the liquid cooling plate with brazing flux is provided. Specifically, the connection relationship is changed to a rotational connection between the clamping plate and the rotating support leg, and the required brazing flux is coated on the clamping plate in advance. Therefore, during the process of advancing the transmission of the liquid cooling plate, the clamping plate tends to rotate due to friction, thereby completing the brazing flux coating on the side wall of the liquid cooling plate.

[0010] A further improvement of the technical solution of the present invention is that: during the transmission process of the clamping disk mentioned above, the liquid cooling plate always has a clamping limit, so the reset force applied to the clamping disk during the transmission of the liquid cooling plate can be used as the clamping force of the clamping disk on the liquid cooling plate. Therefore, the guide coating module is provided with multiple groups and arranged in an array on the guide station in the processing seat, the adjacent transmission gears are meshed with each other, and a fixed column is provided between the adjacent rotating legs, and a reset spring is fixedly provided between two adjacent fixed columns; from the above, it can be seen that the elastic deformation force of the reset spring prompts the clamping disk to reset, so the traction tension always exists as the clamping force when the liquid cooling plate is promoted and transmitted, and after the transmission of the liquid cooling plate is completed, the traction tension resets the clamping disk, avoiding the user to manually enter the guide station for operation, thereby improving convenience and making the liquid cooling plate processing and welding process more automated. Each group of adjacent rotating shafts is rotatably mounted on a suspension located directly above the processing seat. Each group of suspensions is welded with a suspension arm whose other end is fixed to the side wall of the processing seat. A coating component for coating flux is mounted on one of the suspensions, and a coating component for uniformly coating flux is mounted on the other suspension. The distance between the suspension on which the coating component is mounted and the transmission station is greater than the distance between the suspension on which the coating component is mounted and the transmission station.

[0011] Furthermore, when the liquid cooling plate is brazed, the liquid cooling plate needs to be coated with flux to prevent oxidation and improve welding quality. Therefore, coating first and then spreading evenly in this process is the optimal solution for the flux-coated multi-module combination.

[0012] A further improvement of the technical solution of the present invention is that: the coating component includes a sleeve welded at a suspension thereof, an air pump is limitedly installed in the sleeve, a transmission pipe is limitedly connected to the output end of the air pump, connecting pipes are fixedly installed on both sides of the transmission pipe, the other end of which passes through the coating roller, the end face of the coating roller is provided with a coating hole penetrating its roller surface, the coating hole is filled with a sponge layer, an air bag connected to the connecting pipe is provided inside the coating roller, and the coating roller is rotatably connected to the connecting pipe; the specific steps taken for uniform coating of the liquid cooling plate are as follows: the air pump outputs gas to the coating roller, the air bag in the coating roller is inflated and then The coating roller expands, and airbag 1 gradually approaches the inner wall end face of the coating roller. Finally, airbag 1 squeezes the sponge layer, and flux appears on the surface of the sponge layer. At this time, after the liquid cooling plate is transmitted to the coating roller, the coating holes of the coating roller are coated with flux, and the coating roller rotates under the action of force, so as to better complete the uniform and comprehensive coating and ensure that the flux covers the liquid cooling plate. After the flux coating is completed, airbag 1 starts to be evacuated by the air pump. At this time, airbag 1 contracts, and the pressurized state of the sponge layer is released. The flux shrinks into the sponge layer. Compared with the direct spraying of the flux by the nozzle, it can avoid the flux from accidentally dripping onto the processing seat, thereby improving the utilization rate of materials and the processing environment.

[0013] A further improvement of the technical solution of the present invention is that the width of the coating roller is adapted to the width of the liquid cooling plate to be welded, and the widths of the coating roller and the liquid cooling plate to be welded are both smaller than the processing seat.

[0014] A further improvement of the technical solution of the present invention lies in that: the coating assembly includes an extension plate arranged at another suspension, a servo motor with the other end connected to the telescopic rod is installed at the bottom limit of the extension plate, the servo motor is connected to the telescopic rod through a coupling, a scraper is fixedly installed on the telescopic part of the other end of the telescopic rod, a brush for uniform coating is arranged at the bottom of the scraper, and a spring is fixedly installed between the scraper and the extension plate directly above it; wherein the servo motor drives the telescopic rod to rotate, and the telescopic rod drives the scraper with the brush installed to rotate, so as to evenly coat and scrape the surface of the liquid cooling plate coated with the flux, and further, due to the different thicknesses of the liquid cooling plate, when the scraper conflicts with the liquid cooling plate below, the spring is compressed and the telescopic rod contracts.

[0015] A further improvement of the technical solution of the present invention lies in that: the transmission and adsorption module includes a placement seat arranged on the side of the processing seat close to the guide coating module, the placement seat is provided with a liquid-cooled plate embryo to be welded, and suction cups for limiting and fixing the liquid-cooled plate embryo are symmetrically arranged inside the placement seat, and a hose is arranged at the bottom of the suction cup, the other end of which passes through the placement seat to the outside of the processing seat, and the other end of the hose is connected to an air pump 2 installed on the processing seat, and tracks for moving the hose are arranged on both sides of the processing seat; wherein, for the transmission of the liquid-cooled plate embryo and the fixation during welding, the present invention generates negative pressure by suction through the suction cup and the air pump 2, and the liquid-cooled plate embryo is firmly adsorbed by the suction cup, and this fixation can be maintained during transmission and welding, so that the fixation of the liquid-cooled plate embryo in the entire welding process and flow has continuity and consistency; and after the liquid-cooled plate embryo passes through the entire welding process on the processing seat, the position changes greatly, so a hose is provided, and the hose can be reserved in length according to the length of the processing seat.

[0016] A further improvement of the technical solution of the present invention is that: an airbag 2 filled with magnetorheological fluid is arranged in the placement seat, the airbag 2 is located directly below the suction cup, and the placement seat is made of a metal material with strong conductivity.

[0017] A further improvement of the technical solution of the present invention is that: the processing module includes a hydraulic push rod located directly below the processing station, the other end of the hydraulic push rod is connected to a sliding block at the bottom of the placement seat, and the sliding block is located in a slide groove at the bottom of the processing seat, and conductive aluminum sheets are arranged on both sides of the processing station of the processing seat, the conductive aluminum sheets are connected to an external excitation device, and a welding assembly for brazing is arranged at the processing station; wherein when the placement seat enters the welding assembly to complete the brazing, the placement seat is further advanced to the conductive aluminum sheet, and at this time the conductive aluminum sheet and the liquid cooling plate are initially The liquid cooling plate embryo contacts the side wall. At this time, the liquid cooling plate embryo is connected to the external excitation device due to the conductive aluminum sheet to conduct magnetism. The common material of the liquid cooling plate embryo is aluminum, which has strong conductivity and extensibility. At this time, the magnetorheological fluid changes from liquid to solid under the action of the magnetic field, and the airbag 2 expands. Further, the suction of the air pump 2 is cancelled. Finally, the airbag 2 lifts the liquid cooling plate and quickly cancels the limit. Compared with the prior art in which the electric push rod or other rods directly push, because the airbag 2 is in flexible contact with the liquid cooling plate, it can effectively avoid damage to the bottom of the liquid cooling plate.

[0018] The present invention also provides a welding method for processing a liquid cooling plate, and the specific steps are as follows:

[0019] S1: Place the liquid cooling plate blank on the placement seat, then start the second air pump, the suction cup and the second air pump suck air to generate negative pressure, the liquid cooling plate blank is sucked by the suction cup, and after checking its fixation, start the hydraulic push rod;

[0020] S2: During the process of starting the hydraulic push rod, the air pump 1 outputs gas to the coating roller, the airbag 1 in the coating roller is inflated and then expands in the coating roller, the airbag 1 squeezes the sponge layer, and the flux appears on the surface of the sponge layer. After the liquid cooling plate is transferred to the coating roller, the coating holes of the coating roller are coated with flux. After the flux coating is completed, the airbag 1 starts to be evacuated by the air pump, and at this time, the airbag 1 contracts, the pressurized state of the sponge layer is released, and the flux contracts into the sponge layer;

[0021] S3: After the coating is completed, the hydraulic push rod continues to be in the advancing state, and the servo motor drives the telescopic rod to rotate, and the telescopic rod drives the scraper equipped with the brush to rotate, so as to evenly apply the liquid cooling plate surface coated with the brazing agent;

[0022] S4: After the liquid cooling plate blank enters the processing station, the welding assembly completes the brazing of the liquid cooling plate blank. After the welding is completed, the conductive aluminum sheet contacts the side wall of the liquid cooling plate blank, and the conductive aluminum sheet is connected to the external excitation device. Under the action of the magnetic field, the magnetorheological fluid changes from liquid to solid state, and the airbag 2 expands. Further, the suction of the air pump 2 is cancelled. Finally, the airbag 2 lifts the liquid cooling plate, quickly cancels the limit, and implements the unloading.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: the clamping plate is pushed outward, the clamping plate and the rotating legs connected thereto are expanded outward, and the liquid cooling plate is smoothly advanced and is always limited by the clamping plates on both sides, thereby ensuring the stable guidance of the liquid cooling plate during the welding transmission process;

[0024] The gas is output to the coating roller through the air pump, and the airbag in the coating roller expands in the coating roller after being inflated. The airbag gradually approaches the inner wall end face of the coating roller, and finally the airbag squeezes the sponge layer, and the flux appears on the surface of the sponge layer. At this time, after the liquid cooling plate is transmitted to the coating roller, the coating hole of the coating roller is coated with the flux, and the coating roller rotates under the action of the force, so as to better complete the uniform and comprehensive coating, and ensure that the flux covers the liquid cooling plate;

[0025] The suction cup and the air pump generate negative pressure, and the liquid cooling plate blank is firmly adsorbed by the suction cup. This fixation can be maintained during the transmission and welding, so that the fixation of the liquid cooling plate blank in the entire welding process and process is coherent and consistent;

[0026] Through the linkage and cooperation of the guide coating module, the transmission adsorption module and the processing module, the equipment can complete the targeted welding and welding compatibility of the liquid cooling plate, integrate the flux coating before the liquid cooling plate welding, stable transmission and the cancellation of the limit after welding, and improve the welding efficiency of the liquid cooling plate.

[0040] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0041] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0042] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0043] Reference Figure 1-Figure 7 , the present invention provides five technical solutions: Example 1

[0044] A welding device and a processing method for a liquid cooling plate, comprising a processing seat 1 for processing a liquid cooling plate, wherein the processing seat 1 is divided into three partition stations, namely a transmission station 11, a guide station 12 and a processing station 13, wherein a transmission adsorption module is arranged at the transmission station 11, a guide coating module is arranged at the guide station 12, and a processing module is arranged at the processing station 13;

[0045] The guide coating module includes a limiting groove 21 arranged on both sides of the guide station 12 in the processing seat 1, and a clamping plate 22 for guide clamping is arranged in the limiting groove 21. A rotating leg 24 with the other end connected to the rotating shaft 23 is welded on the top of the clamping plate 22. The rotating leg 24 is fixedly connected to the rotating shaft 23, and the rotating shaft 23 is connected to the transmission gear 25 through a connecting key.

[0046] In the first embodiment, after the liquid cooling plate pushed and transported by the transport station 11 in the processing seat 1 passes through the clamping plate 22, there is a movement conflict between the side walls, so the clamping plate 22 is pushed outward, and at this time, the clamping plate 22 and the rotating legs 24 connected thereto are expanded outward, and after the expansion until the clamping plate 22 contacts the side wall of the liquid cooling plate, the liquid cooling plate is smoothly pushed forward and is always limited by the clamping plates 22 on both sides, ensuring the stable guidance of the liquid cooling plate during the welding transmission process;

[0047] Furthermore, when the liquid cooling plate is brazed, it is necessary to coat the liquid cooling plate with flux. In view of this situation, Embodiment 1 provides a method for coating the side wall of the liquid cooling plate with flux. Specifically, the connection relationship is changed to a rotational connection between the clamping plate 22 and the rotating support leg 24. The clamping plate 22 is coated with the required flux in advance. Therefore, during the process of advancing the transmission of the liquid cooling plate, the clamping plate 22 tends to rotate due to friction, thereby completing the flux coating of the side wall of the liquid cooling plate. Example 2

[0048] The clamping disk 22 mentioned in the first embodiment always has a clamping limit on the liquid cooling plate during the transmission process. Therefore, the reset force applied to the clamping disk 22 during the transmission of the liquid cooling plate can be used as the clamping force of the clamping disk 22 on the liquid cooling plate. Therefore, the guide coating module is provided with multiple groups and arranged in an array on the guide station 12 in the processing seat 1. Adjacent transmission gears 25 are meshed with each other, and fixed columns 26 are provided between adjacent rotating legs 24. A reset spring 27 is provided in the fixed sleeve between two adjacent fixed columns 26.

[0049] From the above, it can be seen that the elastic deformation force of the reset spring 27 causes the clamping plate 22 to reset, so the traction force always exists as a clamping force when the liquid cooling plate is promoted and transmitted, and after the liquid cooling plate is transmitted, the traction force resets the clamping plate 22, avoiding the user to manually enter the guide station 12 for operation, thereby improving convenience and making the liquid cooling plate processing and welding process more automated.

[0050] Each group of adjacent rotating shafts 23 is rotatably mounted on a suspension 28 located directly above the processing seat 1. Each group of suspensions 28 is welded with a suspension arm 29 whose other end is fixed to the side wall of the processing seat 1. A coating component for coating the flux is installed on one of the suspensions 28, and a coating component for uniformly coating the flux is installed on the other suspension 28. The distance between the suspension 28 on which the coating component is installed and the transfer station 11 is greater than the distance between the suspension 28 on which the coating component is installed and the transfer station 11.

[0051] Furthermore, when the liquid cooling plate is brazed, the liquid cooling plate needs to be coated with flux to prevent oxidation and improve welding quality. Therefore, coating first and then spreading evenly in this process is the optimal solution for the flux-coated multi-module combination in Example 2. Example 3

[0052] The coating assembly includes a sleeve 31 welded to a suspension 28 thereof, an air pump 32 is limitedly installed inside the sleeve 31, a transmission tube 33 is limitedly connected to the output end of the air pump 32, connecting tubes 35 are fixedly installed on both sides of the transmission tube 33, and the other end of the connecting tube 35 passes through the coating roller 34, the end face of the coating roller 34 is provided with a coating hole 36 penetrating the roller surface, the coating hole 36 is filled with a sponge layer 37, an air bag 38 is provided inside the coating roller 34 for docking with the connecting tube 35, and the coating roller 34 is rotatably connected to the connecting tube 35.

[0053] In the third embodiment, the specific steps taken for uniform coating of the liquid cooling plate are as follows: the air pump 32 outputs gas to the coating roller 34, the airbag 38 in the coating roller 34 is inflated and then expands in the coating roller 34, the airbag 38 gradually approaches the inner wall end face of the coating roller 34, and finally the airbag 38 squeezes the sponge layer 37, and the brazing agent appears on the surface of the sponge layer 37. At this time, after the liquid cooling plate is transmitted to the coating roller 34, the coating hole 36 of the coating roller 34 is coated with the brazing agent, and the coating roller 34 rotates under the action of the force, so as to better complete the uniform and comprehensive coating, and ensure that the brazing agent covers the liquid cooling plate;

[0054] After the flux coating is completed, the airbag 38 starts to be evacuated by the air pump. At this time, the airbag 38 shrinks, and the pressurized state of the sponge layer 37 is released. The flux shrinks into the sponge layer 37. Compared with the direct spraying of the flux by the nozzle, the third embodiment can prevent the flux from accidentally dripping onto the processing seat 1, thereby improving the utilization rate of materials and the processing environment.

[0055] The width of the coating roller 34 is adapted to the width of the liquid cooling plate to be welded, and the widths of the coating roller 34 and the liquid cooling plate to be welded are both smaller than the processing seat 1 . Example 4

[0056] The smearing assembly includes an extension plate 41 arranged at another suspension 28, and a servo motor 43 whose other end is connected to a telescopic rod 42 is installed at a limit position at the bottom of the extension plate 41. The servo motor 43 is connected to the telescopic rod 42 through a coupling, and a scraper is fixedly installed on the telescopic part of the other end of the telescopic rod 42. A brush 44 for uniform smearing is arranged at the bottom of the scraper, and a spring 45 is fixedly installed between the scraper and the extension plate 41 directly above it.

[0057] In the fourth embodiment, the servo motor 43 drives the telescopic rod 42 to rotate, and the telescopic rod 42 drives the scraper equipped with the brush 44 to rotate, so as to evenly apply and scrape the surface of the liquid cooling plate coated with the flux. Furthermore, due to the different thicknesses of the liquid cooling plate, when the scraper collides with the liquid cooling plate below, the spring 45 is compressed and the telescopic rod 42 is contracted. Example 5

[0058] The transmission adsorption module includes a placement seat 51 arranged on the side of the processing seat 1 close to the guide coating module, and a liquid cooling plate blank 52 to be welded is arranged on the placement seat 51. Suction cups 53 for limiting and fixing the liquid cooling plate blank 52 are symmetrically arranged inside the placement seat 51. A hose 54 is arranged at the bottom of the suction cup 53, and the other end of the hose 54 passes through the placement seat 51 to the outside of the processing seat 1. The other end of the hose 54 is connected to an air pump 55 installed on the processing seat 1, and tracks 56 for moving the hose 54 are arranged on both sides of the processing seat 1.

[0059] In the fifth embodiment, for the transport of the liquid cooling plate blank 52 and the fixation during the welding process, the present invention generates negative pressure by suctioning air through the suction cup 53 and the air pump 2 55, and the liquid cooling plate blank 52 is firmly adsorbed by the suction cup 53. This fixation can be maintained during the transport and welding, so that the fixation of the liquid cooling plate blank 52 in the entire welding process and process has coherence and consistency;

[0060] After the liquid cooling plate blank 52 passes through the entire welding process on the processing seat 1 , the position thereof changes greatly, so a hose 54 is provided. The length of the hose 54 can be reserved according to the length of the processing seat 1 .

[0061] The placement seat 51 is provided with a second airbag 58 filled with magnetorheological fluid 57 . The second airbag 58 is located directly below the suction cup 53 . The placement seat 51 is made of a metal material with strong conductivity.

[0062] The processing module includes a hydraulic push rod 61 located directly below the processing station 13, the other end of the hydraulic push rod 61 is connected to a sliding block 62 at the bottom of the placement seat 51, and the sliding block 62 is located in a slide groove at the bottom of the processing seat 1, and conductive aluminum sheets 63 are arranged on both sides of the processing station 13 of the processing seat 1, and the conductive aluminum sheets 63 are connected to an external excitation device, and a welding assembly 64 for brazing is arranged at the processing station 13.

[0063] In the fifth embodiment, after the placement seat 51 enters the welding assembly 64 to complete the brazing, the placement seat 51 is further pushed forward to the conductive aluminum sheet 63. At this time, the conductive aluminum sheet 63 contacts the side wall of the liquid cooling plate embryo 52. At this time, the liquid cooling plate embryo 52 is connected to the external excitation device by the conductive aluminum sheet 63 to conduct magnetism, and the common material of the liquid cooling plate embryo 52 is aluminum, which has strong conductivity and extensibility. At this time, the magnetorheological fluid 57 changes from liquid to solid under the action of the magnetic field, and the airbag 2 58 expands. Furthermore, the suction of the air pump 2 55 is cancelled. Finally, the airbag 2 58 lifts the liquid cooling plate, quickly cancels the limit, and compared with the prior art where the electric push rod or other rod body directly pushes, because the airbag 2 58 is in contact with the liquid cooling plate in a flexible manner, it can effectively avoid damage to the bottom of the liquid cooling plate.

[0064] The present invention also provides a welding method for processing a liquid cooling plate, comprising the following specific steps:

[0065] S1: Place the liquid cooling plate blank 52 on the placement seat 51, then start the air pump 55, the suction cup 53 and the air pump 55 suck air to generate negative pressure, the liquid cooling plate blank 52 is sucked by the suction cup 53, and after checking its fixation, start the hydraulic push rod 61;

[0066] S2: During the process of starting the hydraulic push rod 61, the air pump 32 outputs gas to the coating roller 34, and the airbag 38 in the coating roller 34 is inflated and expanded in the coating roller 34. The airbag 38 squeezes the sponge layer 37, and the brazing agent appears on the surface of the sponge layer 37. After the liquid cooling plate is transferred to the coating roller 34, the coating hole 36 of the coating roller 34 is coated with the brazing agent. After the brazing agent coating is completed, the airbag 38 is evacuated by the air pump, and the airbag 38 shrinks at this time, and the pressurized state of the sponge layer 37 is released, and the brazing agent shrinks into the sponge layer 37;

[0067] S3: After the coating is completed, the hydraulic push rod 61 continues to be in the advancing state, and the servo motor 43 drives the telescopic rod 42 to rotate, and the telescopic rod 42 drives the scraper equipped with the brush 44 to rotate, so as to evenly coat the surface of the liquid cooling plate coated with the flux;
