Description

Technical Field

[0001] The invention relates to the technical field of sheet-type radiator cleaning, in particular to surface pretreatment equipment for processing a sheet-type radiator of a transformer. Background Art

[0002] The transformer fin radiator is a key component in the transformer cooling system. Its performance directly affects the operating efficiency and life of the transformer. In the production process of the transformer fin radiator, it is usually necessary to perform processing steps such as cutting and stamping on the fins. At this time, impurities such as dust and oil will adhere to the surface of the fin radiator, which reduces the surface cleanliness of the fin. Therefore, it is necessary to perform pre-treatment and cleaning operations on the surface of the fin radiator to remove dust, oil, impurities, etc. on the surface of the fin radiator to prevent surface dirt from affecting the adhesion of the subsequent coating sprayed on the surface of the fin. In the processing of the transformer fin radiator, the pre-treatment quality control of the transformer fin radiator is very important, which is directly related to the overall performance and heat dissipation effect of the subsequent fin radiator. The existing technologies involved are as follows:

CN220398137U A cleaning and drying device for heat sink production, comprising a cleaning box and a drying box, the cleaning box being connected to the drying box, with conveying assemblies provided on the front and rear walls of the cleaning box, respectively, for conveying the heat sinks, and cleaning assemblies provided on the upper and lower walls of the cleaning box, respectively, with a drainage pipe fixedly mounted on the rear wall of the cleaning box, and a pair of rotating rollers fixedly mounted on the two ends of the drying box, each with a water-absorbing sponge fixedly mounted on the rotating roller, thereby reducing the efficiency of heat sink cleaning. This solution uses a conveying device to allow the heat sinks to enter the cleaning box one by one continuously and uninterruptedly, and under the action of the cleaning assembly, the upper and lower surfaces of the heat sinks are cleaned at one time, thereby improving the efficiency of heat sink cleaning;

[0004] 2. CN213670843U: An oil cleaning device for aluminum alloy heat sinks, comprising a frame, an oil cleaning device, a workpiece conveying device, and a drying device. The oil cleaning device and the drying device are arranged side by side on the frame. The oil cleaning device comprises a cleaning tank, an ultrasonic generator, and a transducer. The cleaning tank is arranged on the frame. This technical solution feeds the heat sink into the cleaning tank, and the conveyor belt drags the heat sink to move, fully contacting the cleaning liquid in the cleaning tank. The cleaning liquid impacts the oil on the surface of the heat sink, greatly enhancing the cleaning effect.

[0005] In the above-mentioned prior art, the heat sink is cleaned by immersion cleaning or by using a large amount of water in combination with a brush. However, due to the complex structure of the inner cavity of the heat sink of the plate-type radiator, there are many small channels and corners. When performing the above-mentioned cleaning operation, it is easy for sewage containing oil and impurities to enter the interior of the heat sink and mix with the oil in the inner cavity to form dirt that is difficult to remove, which in turn affects the overall performance and operating effect of the subsequent heat sink. In view of this, in-depth research was conducted on the above-mentioned problem, and thus this case was created. Summary of the Invention

[0045] The discharge device includes a material box 23 provided on the upper side of the base 1, with feeding ports 24 evenly provided on the upper side of the material box 23, and discharge ports 25 evenly provided on the front side of the material box 23 corresponding to the feeding ports 24;

[0046] Baffles 26 are evenly arranged inside the material box 23, and buffer rollers 27 are rotatably connected to the inner side of the baffles 26. A limited buffer column 28 is horizontally arranged on the lower side of the material box 23.

[0047] The material moving device includes a column 31 installed on the upper side of the moving base 3, a hydraulic push rod 32 is provided on the upper side of the column 31, the output end of the hydraulic push rod 32 passes through the column 31 and is connected to the moving frame 33, a row of support frames 34 are evenly installed on the front side of the moving frame 33, and a lifting structure is provided on the lower side of the support frame 34;

[0048] The lifting structure includes a lifting gear ring 35, which is rotatably connected to the upper side of the support frame 34 through a bearing. A lifting screw 36 is provided in the middle part of the lifting gear ring 35. The lower side of the lifting screw 36 passes through the support frame 34 and is connected to a lifting block 37. The inner ring of the lifting gear ring 35 is provided with an internal thread matching the lifting screw 36. A lifting motor 38 is installed on one side of the lower side of the support frame 34. The driving end of the lifting motor 38 passes through the support frame 34 and is connected to a driving tooth 39. The driving tooth 39 meshes with the lifting gear ring 35.

[0049] A limit frame 40 is sleeved on the lower side of the lifting screw 36. A bending portion 41 is provided on both sides of the limit frame 40. The upper side of the bending portion 41 is connected to the lower side of the support frame 34 through a spring rod 42. A telescopic airbag 43 is provided on the lower side of the lifting block 37. Rotating pieces 44 are provided on both sides of the lower side of the lifting block 37. An air pump 45 is provided on one side of the upper side of the limit frame 40. The exhaust port of the air pump 45 is connected to the telescopic airbag 43 through a connecting hose 46.

[0050] It should be noted that the upper side of the base 1 is symmetrically provided with a discharge device, a transfer device, an electric slide rail 2, a cleaning rack 4, and a plurality of components arranged in front of the cleaning rack 4. The symmetrically arranged components can be used to alternately perform the discharge, transfer, and surface cleaning pretreatment operations of the transformer fin radiator fins. The symmetrical design can increase the overall operating efficiency of the device, ensure the continuity of the pretreatment process, and increase the efficiency and effect of subsequent transformer fin radiator processing.

[0051] It should be noted that after the heat sink has undergone processing steps such as cutting and stamping, impurities such as dust and oil will adhere to its surface. At this time, the heat sink can be put into the material box 23 through the feeding port 24. The interior of the material box 23 is divided into multiple spaces by the baffle 26, and buffer rollers 27 are provided on both sides of the baffle 26 to slow down the descending speed of the heat sink and prevent the heat sink from colliding with the baffle 26 and being damaged. Then, the limiting buffer column 28 located on the lower side of the material box 23 can limit and fix the vertical position of the heat sink. At the same time, the baffle 26, the buffer roller 27 and the limiting buffer column 28 cooperate to keep the heat sink vertical.

[0052] Then the electric slide rail 2 cooperates with the moving seat 3 to drive the column 31 and multiple components located on the upper side of the column 31 to move to the front side of the material box 23, and makes the multiple groups of support frames 34 on the front side of the moving frame 33 correspond to the discharge port 25 on the front side of the material box 23. Then the hydraulic push rod 32 is operated to push the moving frame 33 to move, and drive the support frame 34 and multiple components located on the lower side of the support frame 34 to extend into the material box 23 through the discharge port 25. The area of ​​the discharge port 25 is large enough and will not cause movement interference with the lifting screw 36. At this time, each support frame 34 corresponds to a heat sink. Then the lifting motor 38 is operated, and through the cooperation of the driving gear 39, the lifting gear ring 35 and the lifting screw 36, the lifting block 37 can be driven to descend vertically, and the lifting block 37, the telescopic airbag 43 and the rotating piece 44 are inserted into the heat sink through the opening 9 on the upper side of the heat sink.

[0053] At this time, the air pump 45 is running, and air can be ventilated into the telescopic airbag 43 through the connecting hose 46, so that the telescopic airbag 43 is expanded as a whole, and the rotating piece 44 can be pushed to rotate, so that the rotating piece 44 is tightly attached to the inner wall of the upper side of the heat sink. At the same time, the telescopic airbag 43 can block the opening 9 on the upper side of the heat sink. The telescopic airbag 43 is made of rubber as a whole, and the expansion volume of the telescopic airbag 43 can be controlled by controlling the air supply of the air pump 45. For this reason, the telescopic airbag 43 will not expand too much and cause deformation of the heat sink. The rotating piece 44 is used to increase the bearing capacity of the heat sink in the vertical direction. At this time, the lifting motor 38 is running again, and the upper side can be driven by the expanded telescopic airbag 43. The blocked heat sink rises and makes the heat sink shoulder close to the bent portions 41 on both sides of the limit frame 40, while squeezing the spring rod 42. The spring rod 42 generates a vertical downward reaction force that can increase the overall fixing and clamping effect of the heat sink, preventing the heat sink from loosening. The elastic limit block 47 located at the lower side of the bent portion 41 can provide buffer protection for the heat sink shoulder. At the same time, the lifting screw 36 rises to separate the lower side of the heat sink from the limit buffer column 28, preventing the limit buffer column 28 from causing movement interference with the heat sink. The lower side of the elastic limit block 47 is provided with an arc groove, which, together with the inflated telescopic airbag 43, can increase the vertical fixing effect of the heat sink, further improving the fixing quality.

[0054] After the fixing is completed, the hydraulic push rod 32 is retracted, and the heat sink located inside the material box 23 can be taken out. During the removal process, the surface of the heat sink will come into contact with the cleaning brush 30, which can remove some dust and impurities, thereby increasing the subsequent cleaning effect. At the same time, the dust can fall into the dust collecting hopper 48 located on the lower front side of the material box 23 for collection.

[0055] A guide rod 50 parallel to the hydraulic push rod 32 is inserted on the upper side of the column 31. One side of the guide rod 50 is connected to the rear side of the movable frame 33. A guide groove is provided on the upper side of the column 31. A guide piece 51 slidably connected to the guide groove is installed on the rear side of the movable frame 33 to increase the stability of the heat sink during movement.

[0056] Then the electric slide rail 2 drives the heat sink to move to the front side of the cleaning rack 4, and pushes out the heat sink again so that the heat sink is inserted between the multiple fixed tubes 8, wherein the fixed tube 8 is provided with a feeding pipe 16 on the upper and lower sides, and the two feeding pipes 16 are respectively connected to the cleaning agent pumping system and the clean water pumping system. This part is the existing technology and will not be repeated. Since the first nozzle 12, the second nozzle 13 and the middle part of the transfer bin 19 are provided with a partition 20, the first nozzle 12, the second nozzle 13 and the transfer bin 19 can be divided into two independent cavities, and the two feeding pipes 16 respectively connected with the cleaning agent pumping system and the clean water pumping system can be used to pass cleaning agent or clean water into the first nozzle 12 and the internal cavity of the transfer bin 19 through the connecting hose 21, and then the two independent cavities inside the first nozzle 12 and the second nozzle 13 can spray cleaning agent and clean water respectively, thereby increasing the cleaning effect of the heat sink;

[0057] When the heat sink needs to be pre-treated for surface cleaning, the driving member 6 is in operation, and the screws 5 on both sides of the front side of the cleaning rack 4 can be driven to rotate at the same time through the cooperation of the synchronous wheel and the synchronous belt, and the multiple fixed tubes 8 and the components on both sides of the fixed tubes 8 are driven to reciprocate in the vertical direction through the lifting seat 7. During the movement, it is possible to choose to spray cleaning agent, clean water or both at the same time according to the use requirements. At the same time, after the fixed tube 8 moves to the lower side of the assembly rack on the front side of the cleaning rack, the limiting push rod can push the first nozzle 12 and the second nozzle 13 on the rear side of the fixed tube 8 to descend. They are all connected to the rotating shaft 10 through the rotating rod 11. Therefore, when the fixed tube 8 is raised to the highest point, it will cooperate with the limiting push plate 18 to push the multiple first nozzles 12 and the second nozzles 13 down, and make the metal block 14 embedded in the middle part of the rotating rod 11 and the magnetic block 15 on the lower side of the fixed tube 8 attract each other, so that the angles of the first nozzles 12 and the second nozzles 13 can be fixed. Then, the driving member 6 cooperates with the lead screw 5 to drive the multiple first nozzles 12 and the second nozzles 13 to descend. The attraction between the magnetic block 15 and the metal block 14 is large enough. When the force of the lead screw 5 is greater than the magnetic attraction force, the angles of the first nozzles 12 and the second nozzles 13 can be changed.

[0058] At this time, the water mist sprayed by the first nozzle 12 and the second nozzle 13 forms an asymmetric impact, which can cover more areas of the workpiece surface, reduce the cleaning blind areas caused by obstruction or dead angles during spraying, and increase the cleaning effect. At the same time, the position of the second nozzle 13 corresponds to the position of the groove on the surface of the heat sink, and the sprayed water mist can be impacted at the dead angle of the groove, thereby increasing the flushing effect and preventing the inside of the groove from being in a dead angle and unable to be cleaned. When the fixed pipe 8 moves to the assembly plate 17 on the lower front side of the cleaning rack 4, the limit push plate 18 pushes the first nozzle 12 and the second nozzle 13 again, so that the first nozzle 12 and the second nozzle 13 are tilted upward, and at the same time the lifting seat 7 performs reciprocating motion in the vertical direction to increase the flushing effect, the feeding port 24 and the discharge port The number of the ports 25 is at least four, the number of the support frames 34 matches the number of the feeding ports 24 and the discharging ports 25, the number of the fixed tubes 8 is at least five, the number of the limiting push plates 18 is twice the number of the support frames 34, the first nozzle 12 and the second nozzle 13 will both rinse both sides of the heat sink and form a symmetrical impact force, so that the heat sink will not be unstable during the flushing process, the first nozzle 12 is configured as a cone as a whole, and the second nozzle 13 is configured as a V-shaped as a whole, wherein the first nozzle 12 with a conical shape can make the sprayed droplets more evenly distributed, thereby increasing the cleaning effect, and the second nozzle 13 with a V-shaped shape can increase the flushing effect inside the heat sink groove, thereby preventing the inside of the groove from being in a dead corner and unable to be cleaned;

[0059] At the same time, since the upper opening 9 of the heat sink is blocked by the telescopic airbag 43, the cleaning wastewater will not enter the interior of the heat sink, causing contamination of the interior of the heat sink. At the same time, under the influence of gravity, the cleaning wastewater will enter the sewage tank 22 instead of entering the interior of the heat sink through the lower opening 9 of the heat sink.

[0060] After the flushing operation is completed, the electric slide rail 2 can drive the heat sink that has been pre-treated by flushing to the upper side of the collection tank 49, and can perform subsequent drying and blowing operations. An inclined liquid guide groove is provided inside the collection tank 49 to facilitate the discharge of collected sewage.

[0061] T-shaped auxiliary grooves are provided on both sides of the front side of the cleaning rack 4, and the two sides of the rear side of the lifting seat 7 are slidably connected to the T-shaped auxiliary grooves to increase the stability of the lifting seat 7 during the lifting process. U-shaped placement racks 52 are evenly installed on the upper side of the sewage tank 22. After the operation of the device is completed, the fixed pipe 8 can be placed on the U-shaped placement rack 52.

[0062] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
