Description

Technical Field

[0001] The invention belongs to the technical field of coating processing, in particular to a coating equipment for surface treatment of a radiator air duct. Background Art

[0002] Rail transit radiators play a vital role in the locomotive cooling system. The radiator air duct must have excellent corrosion resistance in long-term operation to ensure the stability of heat dissipation efficiency and the safety and reliability of the equipment. Once the surface treatment process of the radiator air duct is abnormal, it may cause corrosion inside the air duct, affecting the heat dissipation efficiency, and then causing overheating or main circuit breaker blockage of rail transit locomotive equipment. Moreover, corrosion problems will not only cause equipment failures, resulting in locomotive shutdown and repair, but also seriously shorten the service life of the radiator, affecting the overall efficiency of the cooling tower and the operational reliability of rail transit locomotives.

[0003] The surface treatment process of rail transit radiator ducts mainly relies on manual operation. However, this manual coating method has obvious defects in uniformity and consistency, and it is difficult to meet the high standards for radiator duct surface treatment. This treatment method is not only unstable in process, but also prone to missed coating or uneven thickness, affecting the quality of the coating. In addition, manual operation during manual coating can easily cause the coating stock solution to volatilize, posing a threat to the health of the operator. Long-term inhalation of volatile substances may cause harm to the human body, so there are also hidden dangers in terms of operational safety.

[0004] Some current automatic coating equipment achieves the effect of automatic coating of workpieces by pouring anti-corrosion paint liquid into the workpiece at a high point and adjusting the position of the workpiece using a conveying mechanism or a flipping mechanism. The excess anti-corrosion paint liquid automatically detaches from the workpiece under the action of gravity. Although this type of equipment also achieves automatic coating, the paint flows under the action of gravity, which easily forms an uneven coating on the surface of the workpiece, especially on vertical surfaces or corners. The paint may accumulate excessively or fail to fully cover, resulting in exposed spots or excessive thickness in the treated area. Summary of the invention

[0005] The object of the present invention is to provide a radiator air duct surface treatment filling and coating equipment to solve the problems raised in the above-mentioned prior art.

[0006] Provided is a radiator air duct surface treatment filling and coating equipment, comprising:

[0007] A frame assembly, comprising a base and a turning frame, wherein the turning frame is rotatably connected to the base and is used to fix the workpiece;

[0008] A flip motor, which is used to control the flip frame to rotate relative to the base;

[0009] The filling and coating mechanism comprises a lifting platform and a filling and sealing platform, wherein the lifting platform is used to control the filling and sealing platform to move in a vertical direction;

[0010] A paint conveying mechanism, wherein a paint conveying pipeline of the paint conveying mechanism passes through the potting platform and is communicated with the upper surface of the potting platform.

[0011] As a further embodiment of the present invention, it also includes a fan slide assembly, which includes a slideway, a slideway and a plurality of fans, wherein the slideway is fixedly connected to the base, and the plurality of fans are slidably connected to the slideway through the slideway. The slideway slides on the slideway through a driving action, and the plurality of fans on the slideway are started to dry the radiator air duct, thereby realizing an automated, multi-directional wind combing process and avoiding the unevenness of manual drying.

[0012] As a further embodiment of the present invention: the paint delivery mechanism includes a storage tank, a delivery pump and an output pump, the delivery pump and the output pump are respectively connected to the storage tank, the delivery pump is connected to the upper surface of the potting table through a delivery pipe, and the output pump is connected to the upper surface of the potting table through an output pipe. The input and output of the paint are respectively realized by the storage tank, the delivery pump and the output pump, and the paint flows in one direction to avoid backflow and mixing of the paint in the system. The dual pump design reduces the flow rate changes caused by pressure fluctuations, ensures that the paint is evenly coated inside the air duct, and improves the coating quality.

[0013] As a further embodiment of the present invention: the coating mechanism further comprises an overflow support, the overflow support is arranged in a groove structure along the outer circumference of the sealing platform, and the output pipe forms two branch pipelines which are respectively connected with the upper surface of the sealing platform and the inside of the overflow support. The overflow support is arranged around the sealing platform in a groove structure, and is used to collect overflow paint caused by insufficient sealing or excessive paint, and pump the overflow paint back to the storage tank through the output pipeline to avoid leakage and contamination of the working environment, while protecting the base area of ​​the equipment clean.

[0014] As a further embodiment of the present invention: a ball valve is respectively provided on the two branch pipelines of the output pipe. The corresponding ball valves can be opened according to the requirements of paint overflow or backdrawing, and the paint flow path can be flexibly controlled. Under normal conditions, the branch pipeline connected to the overflow support is closed, and the output pump only processes the main paint flow to avoid wasting power when running at no load.

[0015] As a further embodiment of the present invention: the delivery pump and the output pump are vacuum diaphragm pumps. The diaphragm design prevents the paint from directly contacting the metal parts in the pump, prevents corrosion, and prolongs the life of the equipment.

[0016] As a further embodiment of the present invention, an air duct sealing gasket is arranged around the filling platform, and the connecting part between the paint conveying pipeline of the paint conveying mechanism and the filling platform is limited to the area surrounded by the air duct sealing gasket. The air duct sealing gasket fits the air duct opening to prevent the paint from leaking during the pouring process and ensure the uniform pressure of the paint in the air duct cavity.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] After the radiator is fixed on the flip frame, the coating surface of the radiator can be made opposite to the potting table through the flip motor. The potting table is driven up by the lifting platform to contact the radiator and maintain the seal, and then the paint is transported to the inside of the radiator and between the potting table through the paint conveying mechanism. The paint is poured in the form of gradually immersing the internal air duct of the radiator from bottom to top relative to the radiator, so that the various parts of the air duct structure are fully in contact with the paint. After the coating is completed, the paint inside the radiator is extracted by the paint conveying mechanism, and the flip motor rotates the flip frame again to reset. The coating equipment overcomes the inefficiency and instability of manual coating surface treatment, and reduces the harm to the human body during the coating process. The immersion coating method makes the coating treatment on the surface of the radiator air duct more uniform, ensures the consistency of each area, and improves the surface treatment quality of the radiator air duct.

[0027] However, unnecessary detailed descriptions may be omitted. For example, detailed descriptions of well-known matters and repeated descriptions of substantially the same structures may be omitted. This is to avoid the following description from becoming unnecessarily lengthy and to facilitate understanding by those skilled in the art. In addition, the drawings and the following description are provided to enable those skilled in the art to fully understand the present application and are not intended to limit the subject matter described in the claims.

[0028] See also Figure 1-4 As shown, the radiator duct surface treatment coating equipment in the embodiment of the present invention includes a frame assembly 1, a flip motor 2, a coating mechanism 3 and a paint conveying mechanism 4. The frame assembly 1 includes a base 11 and a flip frame 12, and the flip frame 12 is rotatably connected to the base 11, and the flip frame 12 is used to fix the workpiece. The flip motor 2 is used to control the flip frame 12 to rotate relative to the base 11. The coating mechanism 3 includes a lifting platform 31 and a sealing table 32, and the lifting platform 31 is used to control the sealing table 32 to move in the vertical direction. The paint conveying pipeline of the paint conveying mechanism 4 passes through the sealing table 32 and is connected to the upper surface of the sealing table 32.

[0029] The rotating shafts on both sides of the flip frame 12 are respectively mounted on the base 11 and connected to the base 11 through bearings. The rotating shaft of the flip frame 12 is fixedly connected to the driving shaft of the flip motor 2, and the flip frame 12 can be driven by the flip motor 2 to rotate at a right angle. The lifting platform 31 can be driven to lift and lower by a scissor mechanism or a hydraulic cylinder. Specifically, the scissor mechanism includes a scissor arm and a driving part, and the driving part can be an actuator cylinder, a screw assembly or a pneumatic slide rail. The scissor mechanism has a high degree of compression, a large extension stroke, and a stable straight conveying path. The lifting form of the lifting platform 31 can be selected according to needs, and is not limited here.

[0030] In a specific embodiment, the radiator is fixed to the flip frame 12 by bolts, and the flip motor 2 is controlled by the PLC control system to flip the flip frame 12 180°. After flipping to the right position, the lifting platform 31 is controlled to perform a lifting operation so that the potting platform 32 rises and fits tightly with the radiator air duct opening. At this time, the delivery pipe opening of the paint delivery mechanism 4 passes through the potting platform 32 and is connected to the inside of the radiator air duct. The pump body of the paint delivery mechanism 4 is started to pump the surface treatment stock liquid (paint) into the radiator air duct cavity. Under the sealing effect of the radiator bottom and the potting platform 32, the liquid level of the paint begins to rise and gradually immerses the various structural parts of the air duct, realizing the surface treatment of the air duct coating. After the air duct is completely immersed for a set time, the pump body of the paint delivery mechanism 4 is started to extract the paint in the air duct, and the liquid level of the paint begins to drop until the air duct is completely exposed. Then the lifting platform 31 drives the potting platform 32 to descend, and the flip motor 2 is operated to flip the flip frame 12 180° for reset. After the radiator is removed from the turning frame 12, the surface of the next product is subjected to surface coating treatment.

[0031] The coating equipment also includes a fan slide assembly 5, which includes a slideway 51, a slide 52 and a plurality of fans 53. The slideway 51 is a slide rail controlled by a solenoid valve and driven by a cylinder to slide the slide 52 on the slideway 51. Specifically, there can be two slideways 51, which are fixedly connected to both sides of the base 11 and arranged parallel to the rotation center axis of the flip frame 12, so that the sliding path of the slide 52 avoids the flip frame 12. A plurality of fans 53 are fixed on the slide 52 and can generate wind power after being started.

[0032] After the radiator air duct has completed the coating treatment and the paint inside the air duct has been drawn away, the control system controls the solenoid valves on the two slideways 51 to open, so that the two cylinder top rods extend to push the slide 52, and the slide 52 drives a number of fans 53 to the top of the radiator air duct. At the same time, the fans 53 are started to perform air combing and surface drying treatment on the surface of the radiator air duct. After the radiator air duct is subjected to single-sided air combing and surface drying treatment, the two solenoid valves are closed, the two cylinder top rods contract to push the slide 52 and the fan 53 back to the origin, and at the same time, the flip motor 2 operates to flip the flip frame 12 180° to achieve reset. After the radiator is reset, the two solenoid valves are opened again, so that the two cylinder top rods extend to push the slide 52 and drive the fan 53 to slide to the top of the radiator air duct, and the surface treatment paint on the air duct surface on the other side of the radiator is subjected to air combing and surface drying treatment. After the surface drying treatment of the air comb is completed, the two solenoid valves are closed, the two cylinder top rods are retracted to push the slide 52 and the fan back to the origin, and the filling and coating equipment as a whole returns to the reset state, completing the filling and coating surface treatment of the single product.

[0033] See also Figure 1 and Figure 4 As shown, specifically, an air duct sealing gasket 34 is provided on the potting platform 32, and the air duct sealing gasket 34 can be made of elastic material, such as rubber material or silicone material. The connecting part between the paint delivery pipeline of the paint delivery mechanism 4 and the potting platform 32 is limited to the area surrounded by the air duct sealing gasket 34. After the lifting platform 31 lifts the potting platform 32, the air duct sealing gasket 34 contacts the radiator air duct opening, and the deformation of the air duct sealing gasket 34 enhances the sealing effect between the radiator air duct, ensuring that the paint will not leak out of the air duct or reducing the leakage, thereby reducing the pumping amount of the paint delivery mechanism 4 and improving the processing efficiency of the filling and coating surface treatment.

[0034] Specifically, the paint delivery mechanism 4 includes a storage tank 41, a delivery pump 42 and an output pump 43. The storage tank 41 is used to store the surface treatment stock solution, and the delivery pump 42 and the output pump 43 are respectively connected to the storage tank 41 for inputting and outputting paint to and from the storage tank 41. The delivery pump 42 is connected to the upper surface of the potting platform 32 through the delivery pipe 421, and the output pump 43 is connected to the upper surface of the potting platform 32 through the output pipe 431. The paint infusion in the radiator air duct is controlled by the delivery pump 42, while the paint extraction is controlled by the output pump 43. The input and output of the paint are controlled by two pumps respectively. The dual-pump design ensures the unidirectional flow of the liquid in the system, avoids reverse flow or chaos in the pipeline caused by pressure fluctuations, achieves higher flow control accuracy, and has a higher pumping pressure, thereby improving the delivery efficiency.

[0035] In one embodiment, the paint delivery mechanism 4 may also use a single pump to control the paint input and output, which can achieve the same liquid level control effect, but the pumping efficiency is relatively low.

[0036] The coating mechanism 3 also includes an overflow support 33, which is arranged in a groove structure along the outer circumference of the potting platform 32. When the paint leaks due to insufficient sealing between the radiator air duct and the potting platform 32, or when the paint is overfilled and overflows, the overflow support 33 can store part of the paint through the groove structure to prevent the paint from leaking to the surrounding area and causing pollution. The output pipe 431 forms two branch pipelines that are connected to the upper surface of the potting platform 32 and the inside of the overflow support 33 respectively. In addition to the function of pumping out the paint in the radiator air duct through a branch pipeline of the output pipe 431, the output pump 43 can also pump out the paint in the overflow support 33 through another branch pipeline of the output pipe 431, so that the overflow support 33 always maintains a low liquid level state to prevent the paint from overflowing from the overflow support 33 to the outside.

[0037] A ball valve is provided on each of the two branch pipelines of the output pipe 431 to control the flow of the two branch pipelines. The ball valve connected to the overflow base 33 is opened only when the coating overflows from the filling station 32 or during maintenance to pump the coating overflowed from the filling station 32 back into the storage tank 41. It can be closed at other times to avoid the output pump 43 being partially unloaded and causing a decrease in pumping efficiency.

[0038] In one embodiment, the paint delivery mechanism 4 includes two pumps, which are not linked and can respectively realize the input and output of the paint. The delivery pipelines on the two pumps form two branch pipelines respectively, and the two branch pipelines are respectively connected to the filling platform 32 and the overflow platform 33, both of which can realize the input and output of the paint and realize the extraction of the paint in the overflow platform 33.

[0039] Furthermore, the delivery pump 42 and the output pump 43 are vacuum diaphragm pumps. The vacuum diaphragm pump uses a diaphragm as a sealing component, which can completely isolate the paint liquid from the driving mechanism, prevent liquid leakage from contacting the core components of the pump, and avoid corrosion of the internal structure of the pump. The anti-corrosion paint liquid has a certain viscosity and even contains a small amount of solid particles. The vacuum diaphragm pump has a strong adaptability to high-viscosity media and granular liquids, is not easy to clog, and can ensure smooth delivery. The sealing and non-volatile design of the vacuum diaphragm pump can effectively reduce the volatilization of solvents in the paint liquid, while avoiding coating defects caused by gas mixing during transportation.

[0040] It should be noted that the present application is not limited to the above-mentioned embodiments. The above-mentioned embodiments are only examples, and the embodiments having the same structure as the technical idea and exerting the same effect within the scope of the technical solution of the present application are all included in the technical scope of the present application. In addition, without departing from the scope of the main purpose of the present application, various modifications that can be thought of by those skilled in the art to the embodiments and other methods of combining some of the constituent elements in the embodiments are also included in the scope of the present application.
