In addition, it should also be understood that when the terms "include" and / or "comprise" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0030] Term explanation:
[0031] Dipping: Immerse the sand core into the coating to cover the surface of the sand core.
[0032] Coating fixture: A device used to clamp the sand core.
[0033] In order to solve the problems mentioned in the background technology, in this embodiment, an automatic cleaning device is adopted to improve the cleaning speed and quality, reduce the labor intensity of workers, and ensure the continuous and efficient operation of the fixture. Moreover, the cleaning quality of the dipping fixture is guaranteed.
[0034] As Figure 2 shown, in this embodiment, a cleaning device for the dipping fixture 1 is proposed, which includes a cleaning tank 2 and a blowing system. The blowing system includes a blowing pipe and a blowing nozzle. The blowing pipe is installed in the cleaning tank 2. The blowing pipe includes an outer pipe, an inner pipe and a connecting pipe. The outer pipe is arranged in a ring shape on the periphery of the cleaning tank 2. The inner pipe is arranged in the middle inside the annular outer pipe. The outer pipe and the inner pipe are in the same plane.

The blowing nozzle is arranged on the inner side of the outer pipe, and the blowing nozzles are arranged on both sides of the inner pipe.
[0035] After the dip coating is completed, the robot drives the jig 1 to a fixed position above the cleaning device. The jig moves downward, and the cleaning liquid is sprayed from the spray nozzle to clean the jig. After the jig is completely cleaned, the water spraying stops. The jig starts to move upward, and the air blowing is turned on to blow-dry the jig. When it reaches the original position, the air blowing stops. Through this cleaning device, the surface of the dip coating jig can be well cleaned, eliminating manual cleaning, reducing the intensity of manual cleaning, and improving the cleaning efficiency. Moreover, through the setting of the outer pipe, inner pipe, and connecting pipe, it will not block the lifting process of the dip coating jig 1, and it realizes the all-round cleaning and air-drying inside and outside the dip coating jig 1, avoiding the residual coating on the inner side of the dip coating jig 1, reducing the manual labor intensity while improving the cleaning quality and effect.
[0036] In this embodiment, the spraying system is divided into a water spraying system 3 and an air jetting system 4; as Figure 3 shown, the water spraying system 3 includes a spray water pipe installed in the cleaning tank 2. The spray water pipe includes an outer water pipe 33, an inner water pipe 34, and a connecting water pipe 35. The outer water pipe 33 is annular, the inner water pipe 34 is arranged inside the annular outer water pipe 33, the connecting water pipe 35 connects the two from the bottom sides of the outer water pipe 33 and the inner water pipe 34, and a water spray nozzle 36 is arranged on the inner side of the outer water pipe 33. Fixing the water spray nozzle 36 on the water pipe instead of on the pool wall 27 of the cleaning tank 2 has little impact on the pool body, is convenient for replacement, and this water spray nozzle 36 adopts a non-universal structure, which can provide greater water pressure and better cleaning effect.
[0037] As Figure 4 shown, the air jetting system 4 includes a spray air pipe installed in the cleaning tank 2. The spray air pipe includes an outer air pipe 45, an inner air pipe 46, and a connecting air pipe 44. The outer air pipe 45 is annular, the inner air pipe 46 is arranged inside the annular outer air pipe 45, the connecting air pipe 44 connects the two from the bottom sides of the outer air pipe 45 and the inner air pipe 46, and air jet nozzles 43 are arranged on both sides of the inner air pipe 46. By arranging the water spraying system 3 and the air jetting system 4 separately, the water spraying system 3 and the air jetting system 4 can respectively carry out wetting and drying treatments on the jig, reducing the influence of the water and air system brought by a single pipe.
[0038] As Figure 3 shown, the outer water pipe 33 is rectangular, the inner water pipe 34 is a pair of straight pipes arranged in parallel, and the inner water pipe 34 is parallel to one side of the outer water pipe 33. The connecting water pipe 35 is in a U shape, and the two ends on the upper side of the connecting water pipe 35 are respectively connected to the outer water pipe 33 and the inner water pipe 34. This layout makes the structure of the water spraying pipeline more stable, the distribution of water flow during water spraying more uniform, and is beneficial to the comprehensive cleaning of the jig.
[0039] As Figure 4As shown, the outer air pipe 45 is rectangular, the inner air pipes 46 are a pair of straight pipes arranged in parallel, and the inner air pipes 46 are parallel to one side of the outer air pipe 45. The connecting air pipe 44 is U-shaped, and the two ends on the upper side of the connecting air pipe 44 are respectively connected to the outer air pipe 45 and the inner air pipes 46. This structural design ensures the stability of the jetting system 4 and the uniformity of jetting, and can effectively dry the moisture on the fixture.
[0040] As Figure 5 , Figure 6 shown, the outer water pipe 33 is located above the outer air pipe 45, and the inner water pipes 34 and the inner air pipes 46 are parallel and arranged alternately; the connecting water pipe 35 is perpendicular to the connecting air pipe 44, wherein the plane where the connecting water pipe 35 is located is perpendicular to the inner water pipes 34, and the plane where the connecting air pipe 44 is located is coplanar with the inner air pipes 46. The nozzles are arranged around, and the water spray nozzles 36 and the air jet nozzles 43 are arranged vertically up and down, so that the fixture can be fully cleaned and blown. The arrangement of the water spray pipe and the air jet pipe enables the water spraying and air jetting to work in coordination, ensuring the continuity and high efficiency of the cleaning and drying processes.
[0041] The water spraying system 3 further includes a water pump 31 and a water inlet pipe 32. One end of the water inlet pipe 32 is connected to the water pump 31, and the other end is connected to the connecting water pipe 35. The water pump 31 provides stable water pressure to ensure the normal operation of the water spraying system 3, and the connection of the water inlet pipe 32 ensures sufficient water source and smooth water flow, thereby guaranteeing the cleaning effect.
[0042] The air jetting system 4 further includes an air inlet pipe 41. The air inlet end of the air inlet pipe 41 is externally connected to a gas source, the air outlet end of the air inlet pipe 41 is connected to the outer air pipe 45, and an electromagnetic valve 42 for opening and closing is further provided on the air inlet pipe 41. The setting of the electromagnetic valve 42 can realize the automatic control of the air jetting system 4 and ensure the stability of the air flow and efficient drying.
[0043] As Figure 7 shown, the cleaning tank 2 includes support columns 22 and cross bars 26. The support columns 22 and the cross bars 26 form the frame structure of the cleaning tank 2. A pool wall 27 is arranged inside the frame structure. The bottom side of the pool wall 27 has a pool bottom 23, and a baffle 21 is arranged on the top side. The baffle 21 has an opening in the middle. The pool wall 27, the pool bottom 23 and the baffle 21 enclose a water-containing space.
[0044] The support columns 22 are used to fix the cleaning tank 2, and the frame, the pool wall 27 and the pool bottom 23 form the main structure of the cleaning tank 2. The baffle 21 is located at the upper part of the cleaning tank 2 to block the splashed paint, etc. generated during the cleaning and blowing processes, ensuring the cleanliness around the cleaning tank 2. There is no need for an energy storage tank, the structure is simple, and the water and gas are directly ejected from the water spraying system 3 and the air jetting system 4, which is convenient for maintenance.
[0045] The bottom of the pool 23 is a conical structure, and a sewage outlet is provided at the lowest part of the conical bottom of the pool 23. The bottom of the pool 23 is provided with a water return hole 24, and the water return hole 24 is located in the upper middle part of the bottom of the pool 23. The water pump 31 is communicated with the water return hole 24 through a water return pipe 37.
[0046] The bottom of the pool 23 is a conical structure, which is beneficial to the separation of water and dirt. The sewage discharge hole 25 is located at the bottom of the conical structure to discharge the impurities after cleaning, ensuring the cleanliness of the cleaning pool 2 and the convenience of sewage discharge. The water outlet hole is located in the upper middle part of the bottom of the pool 23 and is used to send the supernatant liquid into the water pump 31 through the water return pipe 37. The setting of the water return hole 24 can recycle the water in the cleaning pool 2 into the system, improve the utilization efficiency of water resources, and reduce waste.
[0047] The cleaning process of the dip coating fixture 1 by this cleaning device is as follows:
[0048] When the requirements for fixture cleaning are reached according to the program setting, after the robot drives the fixture to rotate to the fixed position above the cleaning pool 2, it starts to move downward. At the same time, the robot feeds back a signal to the control system of the water pump 31, and the water pump 31 starts. Water is pumped from the water outlet hole of the cleaning pool 2 to the water pump 31 through the water return pipe 37, and then the water pump 31 conveys the water to the spray pipe and sprays it out from the spray nozzle 36. As the fixture moves downward, the water sprayed by the nozzle cleans the fixture. After the fixture is cleaned, it moves downward to the fixed position, and the robot feeds back a signal to the control system of the water pump 31 to stop the spray cleaning.
[0049] The robot starts to move upward. The robot feeds back a signal to the air jet control system, and the electromagnetic valve 42 opens. Gas enters the air jet nozzle 43 from the air jet pipe to start air jetting. The residual water and coating on the surface of the fixture are blown clean through air jetting, further improving the cleanliness of the fixture. The fixture continues to move upward to the original rotating position, and the robot feeds back a signal to the air jet control system, and the electromagnetic valve 42 closes, and the air jetting ends.
[0050] Through this cleaning device, the dip coating fixture 1 is fully automatically cleaned. The robot transports the fixture, uses the water spraying system 3 to clean the surface of the fixture, and then uses the air blowing system to blow the residual water and coating on the surface of the fixture clean. The cleaning efficiency is fast, the cleaning quality is high, it completely replaces manual cleaning, improves the automation degree, and reduces the labor intensity of personnel. At the same time, the structure of the cleaning pool 2 is convenient for the separation of water and dirt and the cleaning of dirt, reducing the labor intensity of cleaning the cleaning pool 2, and the water in the cleaning pool 2 can be recycled.
[0051] In other embodiments, the fixture can also be placed in the ultrasonic cleaning pool 2 and cleaned by ultrasonic vibration, and then the surface of the fixture is blown clean by air jetting, which can also meet the requirements for cleaning the fixture.
[0052] Although the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, it is not a limitation on the protection scope of the present invention. Those skilled in the art should understand that various modifications or deformations that can be made without creative efforts on the basis of the technical solution of the present invention are still within the protection scope of the present invention.
