[0083] As Figures 1 to 15 shown, in an embodiment of the present utility model, a multi-station combined cleaning device is provided, which includes a loading station 11, a surge cleaning chamber 2, a first partition chamber 13, a spray cleaning chamber 3, a second partition chamber 14, a rinsing chamber 4, a drying chamber 5, a vacuum drying chamber 6, and an unloading station 12 arranged horizontally in sequence, and also includes a workpiece carrier and a main transmission mechanism 7 for transporting the workpiece carrier. Among them:

[0084] The loading station 11 is provided with a loading platform 111 and a first platform lifting mechanism 112 for driving the loading platform 111 to lift. A loading transmission mechanism 113 is arranged on the loading platform 111. The loading transmission mechanism 113 on the loading platform 111 is used to transport the workpiece carrier from the loading platform 111 into the surge cleaning chamber 2, specifically to the surge roller 221a on the surge transmission mechanism 221.

[0085] The surge cleaning chamber 2 is provided with a surge water tank 21, a surge stage 22, a surge lifting mechanism 23 and a surge cleaning mechanism 24. The surge lifting mechanism 23 is used to lift and lower the surge stage 22 so that the surge stage 22 can be immersed in the surge water tank 21, even at the bottom. The surge stage 22 includes a surge transmission mechanism 221 for transporting the workpiece carrier in and out of the surge cleaning chamber 2. The surge transmission mechanism 221 includes a number of surge rollers 221a capable of carrying the workpiece carrier and a surge motor 221b for driving the surge rollers 221a to rotate. The surge cleaning mechanism 24 is used to perform surge cleaning on the workpieces in the surge water tank 21. The surge cleaning mechanism 24 includes a first spray row 241 with multiple spray nozzles and a first air blowing row 242 with multiple air blowing nozzles. Both the first spray row 241 and the first air blowing row 242 are located in the surge water tank 21. Water is injected into the surge water tank 21. During cleaning, the workpieces are immersed in the water. The first spray row 241 sprays, and at the same time, the first air blowing row 242 blows air, so as to form bursting and tumbling water bubbles in the water, thereby realizing the surge cleaning of the workpieces. Generally, detergents are placed during the surge cleaning process.

[0086] The conveyor chain 71 of the main transmission mechanism 7 sequentially passes through the first partition chamber 13, the spray cleaning chamber 3, the second partition chamber 14, the rinsing chamber 4 and the air drying chamber 5. The main transmission mechanism 7 is used to transport the workpiece carrier from the first partition chamber 13 to the air drying chamber 5. The main transmission mechanism 7 includes two groups arranged in parallel. Each group includes a conveyor chain 71, a number of conveyor rollers 72 distributed on the conveyor chain 71 and a main sprocket 73 for driving the conveyor chain 71 to move. The workpiece carrier is transported on the conveyor rollers 72 of the two conveyor chains 71. The surge cleaning chamber 2, the first partition chamber 13, the spray cleaning chamber 3, the second partition chamber 14, the rinsing chamber 4 and the air drying chamber 5 are all provided with lifting doors arranged front and back. The lifting doors are used for the entry and exit of the workpiece carrier, and at the same time can close the chamber to reduce noise and water spillage. The lifting doors can be driven by cylinders to lift.

[0087] The spray cleaning chamber 3 is provided with a spray cleaning mechanism 31 for spray cleaning the workpieces and a spray lifting mechanism 32 for lifting and lowering the spray cleaning mechanism 31. Generally, detergents are also placed during the spray cleaning process. The spray cleaning mechanism 31 includes a second spray row 311 with multiple spray nozzles and a second air blowing row 312 with multiple air blowing nozzles.

[0088] The rinsing chamber 4 is provided with a rinsing cleaning mechanism 41 for rinsing the workpieces and a rinsing lifting mechanism 42 for lifting and lowering the rinsing cleaning mechanism 41. Generally, detergents are not placed during the rinsing process. If cleaning iron workpieces or other workpieces prone to rusting, rust inhibitors, etc. are added as needed. The rinsing cleaning mechanism 41 includes a third spray row 411 with multiple spray nozzles and a third air blowing row 412 with multiple air blowing nozzles.

[0089] The air-drying chamber 5 is provided with a hot-air drying mechanism 51 for blowing hot air to dry the workpiece, and an air-drying lifting mechanism 52 for lifting the hot-air drying mechanism 51. In the air-drying chamber 5, large-area water stains on the surface of the workpiece are blown away by blowing hot air, and large-area air blowing drying is achieved. The hot-air drying mechanism 51 includes an air tank 511, an air heating element 512 connected to the air tank 511 through an air pipe, and a fourth air blowing row 513 connected to the air heating element 512. The air-drying lifting mechanism 52 is used to lift and lower the fourth air blowing row 513, and the air heating element 512 is an air heating element for heating the air flow gas flowing out of the air tank 511. The air heating element 512 includes an electric heating element and a metal shell. The electric heating element is installed in the metal shell and is separated from the air flow by an insulating material to prevent short circuit and electric shock. The air pipe led out from the air tank 511 is connected to the metal shell, introducing the cold air in the air tank 511 around the electric heating element. The electric heating element heats the cold air to obtain hot air, and then the hot air is ejected through the air-drying nozzles on the fourth air blowing row 513.

[0090] The vacuum drying chamber 6 is provided with a vacuum drying mechanism 61 and a vacuum transmission mechanism 62. The vacuum drying mechanism 61 is used to heat the workpiece, evaporate the water stains on the surface of the workpiece, and suck the vacuum drying chamber 6 through a vacuum pump 615, and then suck the evaporated water stains to achieve drying. The vacuum transmission mechanism 62 is used to transport the workpiece carrier in and out of the vacuum drying chamber 6. The vacuum drying chamber 6 can effectively dry the water stains remaining in the fine holes, deep holes or dead corners of the workpiece. The vacuum drying mechanism 61 includes a drying heating tube 611, a vacuum hood 612, a vacuum lifting mechanism 613, a moisture filter 614 and a vacuum pump 615. The drying heating tube 611 and the vacuum hood 612 are arranged inside the vacuum drying chamber 6. The drying heating tube 611 can be an infrared heating tube or a common heating tube. The moisture filter 614 and the vacuum pump 615 are arranged outside the vacuum drying chamber 6. The vacuum lifting mechanism 613 is used to lift and lower the vacuum hood 612, so that when the vacuum hood 612 descends, it can cover the infrared heating tube and the common heating tube to form a sealed space. Thus, through the suction of the vacuum pump 615, a negative pressure vacuum is formed in the sealed space formed by the vacuum hood 612, and then the water turned into water vapor inside is extracted to achieve vacuum drying. Specifically, the vacuum pump 615 is connected to the moisture filter 614, and the moisture filter 614 is then connected to the vacuum hood 612. When sucking the air and moisture inside the vacuum hood 612, most of the moisture is first filtered by the moisture filter 614 through a conduit, avoiding too much moisture directly entering the vacuum pump 615 and damaging the vacuum pump 615. The vacuum transmission mechanism 62 includes a vacuum chamber sprocket and a vacuum chamber chain driven by the vacuum chamber sprocket. The vacuum transmission mechanism 62 can also adopt the same structure as the main transmission mechanism 7. Or the vacuum transmission mechanism 62 is an extension of the main transmission mechanism 7, that is, the main transmission mechanism 7 is also used to transport the workpiece carrier in and out of the vacuum drying chamber 6.

[0091] The blanking position 12 is provided with a blanking carrier table 121 and a second carrier lifting mechanism 122 for driving the blanking carrier table 121 to lift. A blanking transmission mechanism 123 is arranged on the blanking carrier table 121. The blanking transmission mechanism 123 on the blanking carrier table 121 is used to transport the workpiece carrier to the return transmission line 7b. A rear-end transmission line 7a is also arranged between the vacuum drying chamber 6 and the blanking position 12.

[0092] A return transmission line 7b is also arranged between the bottom of the blanking position 12 and the bottom of the loading position 11. The return transmission line 7b is located at the bottom of the main transmission line. The return transmission line 7b is used to return the workpiece carrier on the blanking carrier table 121 of the blanking position 12 to the loading carrier table 111 of the loading position 11.

[0093] In one embodiment, the spray row is composed of a spray plate. A number of flow channels are arranged inside the spray plate. A spray nozzle is arranged at each flow port. Water from the water pipe enters the spray plate, is divided into a number of flow channels, and then is ejected by the spray nozzles.

[0094] 2. In one embodiment, as Figure 1 、 Figure 6 、 Figures 10 to 12As shown in the figure, it further includes a workpiece carrier position adjustment mechanism 8, which is respectively arranged in the spray cleaning chamber 3, the rinsing chamber 4 and the air drying chamber 5, corresponding to the spray workpiece carrier position adjustment mechanism 8a, the rinsing workpiece carrier position adjustment mechanism 8b, and the air drying workpiece carrier position adjustment mechanism 8c. The position adjustment mechanism 8 includes a drive shaft 81, a return member 82 rotatably arranged at one end synchronously on the drive shaft 81, and a return drive mechanism 83 for driving the drive shaft 81 to rotate. A rubber pad 821 is arranged at the end of the return member 82 away from the drive shaft 81. The drive shaft 81 is arranged below the top of the conveyor chain 71, specifically passing through between the top and the bottom of the conveyor chain 71 and being vertically arranged with respect to the conveyor chain 71. A drive arm 84 is arranged at one end of the drive shaft 81. The return drive mechanism 83 is a cylinder, and the end of the drive arm 84 away from the drive shaft 81 is connected to the telescopic rod of the cylinder. The return drive mechanism 83 drives the drive arm 84 to rotate, so that the drive shaft 81 and the return member 82 rotate synchronously, thereby pulling the workpiece carrier back. The position adjustment mechanism 8 further includes a non-return and over-return member 85, and the non-return and over-return member 85 is closer to the loading position 11 than the return member 82, that is, the direction in which the non-return and over-return member 85 points to the drive shaft 81 is the transmission direction of the conveyor chain 71; the distance between the non-return and over-return member 85 and the drive shaft 81 is greater than the length of the workpiece carrier in the transmission direction of the transmission chain, so that the workpiece carrier can be accommodated between the non-return and over-return member 85 and the drive shaft 81. The non-return and over-return member 85 includes a non-return mounting seat 851 and a non-return and over-return block 852. The non-return mounting seat 851 is provided with a mounting accommodation groove 851a, and a spring mounting opening 851b is arranged at the bottom of the mounting accommodation groove 851a. A return spring 853 is installed in the spring mounting opening 851b. The non-return and over-return block 852 has a hinge portion 852a and a non-return portion 852b. A one-way inclined top surface 852b1 is arranged at the top of the non-return portion 852b, and the one-way inclined top surface 852b1 is arranged obliquely upward in the direction pointing to the drive shaft 81. The non-return and over-return block 852 is hinged and buried in the mounting accommodation groove 851a. Specifically, the hinge portion 852a of the non-return and over-return block 852 is hinged to the side of the mounting accommodation groove 851a away from the return spring 853, and the return spring 853 abuts against the bottom of the non-return portion 852b, so that all or part of the one-way inclined top of the non-return portion 852b extends out of the mounting accommodation groove 851a. The non-return and over-return member 85 can realize the one-way transmission of the workpiece carrier. When the workpiece carrier is pulled back by the return member 82, if the pulled-back distance exceeds the predetermined stroke, the non-return portion 852b of the non-return and over-return member 85 can play a non-return role, preventing the return member 82 from pulling back the workpiece carrier by too large a stroke, so that the workpiece carrier can be accurately positioned between the return member 82 and the non-return and over-return member 85, completing the pre-positioning of the workpiece carrier, enabling the hole positions of the workpieces on the workpiece carrier to be aligned with the spray nozzles and the air blowing nozzles, thereby being more conducive to fully cleaning the workpieces and reducing the occurrence of the situation where local or blind corners cannot be cleaned due to the insufficient coverage of the spray nozzles and the air blowing nozzles.

[0095] Specifically, according to the specifications of different workpiece carriers and workpieces to be cleaned, the operator pre-performs preset positioning and alignment calibration in the cleaning chamber, that is, pre-places the workpiece carrier between the corresponding return piece 82 and the over-reverse stop piece 85 in the cleaning chamber to determine the predetermined position, and then enables the spray nozzles on the corresponding spray row and the air nozzles on the air blowing row in the cleaning chamber to be aligned with the deep holes or fine holes of the workpiece to be cleaned at the predetermined position. After the calibration is completed, when cleaning the workpiece, when the workpiece carrier flows into the cleaning chamber and stays waiting for cleaning, the induction element such as an optoelectronic switch or a grating is used to identify whether the workpiece carrier is at the predetermined position. When the workpiece carrier is transported past the predetermined position by the conveying chain 71 and the conveying roller 72, the return piece 82 returns the workpiece carrier to the predetermined position. When the return force of the return piece 82 is too large, in order to avoid the workpiece carrier flowing backward too far, the over-reverse stop piece 85 stops the reverse flow of the workpiece carrier. In this way, it can be ensured that the workpiece carrier is at the predetermined position when staying inside the cleaning chamber, realizing precise positioning of the workpiece carrier.

[0096] 3. In another embodiment, as Figure 1 、 Figures 13 to 15 shown, the surge cleaning chamber 2, the spray cleaning chamber 3, and the rinsing chamber 4 are all provided with water collecting basins, namely the surge water collecting basin, the spray water collecting basin, and the rinsing water collecting basin respectively. Each water collecting basin is correspondingly provided with a sewage reuse mechanism 9, which are respectively the surge sewage reuse mechanism 9a, the spray sewage reuse mechanism 9b, and the rinsing sewage reuse mechanism 9c. The sewage reuse mechanism 9 includes a water storage tank 91, a sewage pump 92, and a sewage filter 93. A partition 913 is provided inside the water storage tank 91, which divides the inside of the water storage tank 91 into a sedimentation chamber 911 and a water storage chamber 912. An inlet 911a communicating with the water collecting basin is opened at the top of the sedimentation chamber 911, and a filter residue net 911b is provided at the inlet 911a. A communication port 913a communicating with the sedimentation chamber 911 and the water storage chamber 912 is opened at the bottom of the partition 913. A slag blocking plate 914 adjacent to the communication port 913a is provided inside the water storage chamber 912. A reused water heating pipe 915 is also provided at the bottom inside the water storage chamber 912. A liquid level gauge 916 is also provided in the water storage chamber 912. The sewage pump 92 is used to suck the water in the water storage chamber 912, and the sewage filter 93 is respectively connected to the sewage pump 92 and the water pipe communicating with the corresponding spray row.

[0097] Working process:

[0098] Install the workpiece to be cleaned on the workpiece carrier of the loading platform 111 located at the loading position 11, and the first platform lifting mechanism 112 drives the loading platform 111 to rise to drive the workpiece carrier to a predetermined height;

[0099] The loading and conveying mechanism 113 is started, and the workpiece carrier is transported from the loading platform 111 to the surge carrier 22 in the surge cleaning chamber 2. There is enough water in the surge water tank 21. The surge lifting mechanism 23 drives the surge carrier 22 to descend to the bottom of the surge water tank 21, so as to completely immerse the surge carrier 22 in the water. Then, the workpiece on the workpiece carrier is subjected to surge cleaning by the surge cleaning mechanism 24;

[0100] After the surge cleaning is completed, the surge carrier 22 rises, and the surge conveying mechanism 221 transports the workpiece carrier on the surge carrier 22 to the conveyor chain 71 of the main conveying mechanism 7. The conveyor chain 71 transports the workpiece carrier through the first partition chamber 13 and the spray cleaning chamber 3 until the workpiece carrier is sent to the positioning mechanism 8 in the spray cleaning chamber 3. Specifically, the workpiece carrier is placed between the return piece 82 and the over-running check piece 85 of the positioning mechanism 8, so as to complete the positioning of the workpiece carrier in the spray cleaning chamber 3. Then, the spray lifting mechanism 32 drives the spray cleaning mechanism 31 to descend, so that the spray cleaning mechanism 31 sprays and cleans the workpiece on the workpiece carrier; wherein, the positioning mechanism 8 is used to enable the workpiece carrier to accurately stay at a predetermined position in the spray cleaning chamber 3, that is, between the return piece 82 and the over-running check piece 85 of the positioning mechanism 8, so that the spray nozzles on the second spray row 311 and the air nozzles on the second air blowing row 312 can be respectively aligned with the corresponding hole positions or surfaces on the workpiece carrier, improving the coverage and efficiency of spray cleaning, and effectively avoiding the problem of incomplete spray cleaning in blind corners and blind holes;

[0101] After the spray cleaning is completed, the spray cleaning mechanism 31 rises to avoid blocking the workpiece carrier, so that the workpiece carrier can be transported out of the spray cleaning chamber 3 by the main conveying mechanism 7 and pass through the second partition chamber 14 and the rinsing chamber 4 until it enters the positioning mechanism 8 in the rinsing chamber 4. Specifically, the workpiece carrier is placed between the return piece 82 and the over-running check piece 85 of the positioning mechanism 8, so as to complete the positioning of the workpiece carrier in the rinsing chamber 4. Then, the rinsing lifting mechanism 42 drives the rinsing cleaning mechanism 41 to descend, so that the rinsing cleaning mechanism 41 rinses the workpiece on the workpiece carrier; wherein, the positioning mechanism 8 is used to enable the workpiece carrier to accurately stay at a predetermined position in the rinsing chamber 4, that is, between the return piece 82 and the over-running check piece 85 of the positioning mechanism 8, so that the spray nozzles on the third spray row 411 and the air nozzles on the third air blowing row 412 can be respectively aligned with the corresponding hole positions or surfaces on the workpiece carrier, improving the coverage and efficiency of rinsing cleaning, and effectively avoiding the problem of incomplete rinsing in blind corners and blind holes;

[0102] After the rinsing is completed, the rinsing and cleaning mechanism 41 rises to avoid blocking the workpiece loading fixture, enabling the workpiece loading fixture to be transported out of the rinsing chamber 4 by the main transfer mechanism 7 and enter the air drying chamber 5 until it reaches the positioning mechanism 8 in the air drying chamber 5. Specifically, the workpiece loading fixture is placed between the return piece 82 and the anti-reverse stop piece 85 of the positioning mechanism 8, thereby completing the positioning of the workpiece loading fixture in the air drying chamber 5. Then, the air drying lifting mechanism 52 drives the hot air drying mechanism 51 to descend, enabling the hot air drying mechanism 51 to conduct hot air drying on the workpieces on the workpiece loading fixture. Among them, the positioning mechanism 8 enables the workpiece loading fixture to accurately stay at a predetermined position in the air drying chamber 5, that is, between the return piece 82 and the anti-reverse stop piece 85 of the positioning mechanism 8, so that the air drying nozzles on the fourth air blowing row 513 can be aligned with the corresponding holes or surfaces on the workpiece loading fixture, improving the coverage area of hot air blowing and the hot air drying efficiency, and effectively avoiding the problem of incomplete hot air drying in blind corners and blind holes.

[0103] After the hot air drying is completed, the hot air drying mechanism 51 rises to avoid blocking the workpiece loading fixture, enabling the workpiece loading fixture to be transported out of the air drying chamber 5 by the main transfer mechanism 7 until it enters the vacuum drying chamber 6. The vacuum lifting mechanism 613 drives the vacuum hood 612 to descend and cover the workpiece loading fixture. The drying heating tube 611 heats up to heat and evaporate the residual water stains in the fine holes, deep holes or dead corners of the workpiece loading fixture. The vacuum pump 615 is started to suck out the air and the evaporated water vapor in the vacuum hood 612. On the way, the air or water vapor passes through the pipeline and enters the moisture filter 614 to filter the moisture, and then is pumped out by the vacuum pump 615.

[0104] After the vacuum drying is completed, the vacuum hood 612 rises. The workpiece loading fixture is transported from the vacuum drying chamber 6 to the rear-end transfer line 7a and is conveyed by the rear-end transfer line 7a to the unloading platform 121 at the unloading position 12. The operator then removes the cleaned workpieces from the workpiece loading fixture, and the second platform lifting mechanism 122 drives the unloading platform 121 to descend, thereby lowering the workpiece loading fixture. The unloading transfer mechanism 123 on the unloading platform 121 transports the workpiece loading fixture from the unloading platform 121 to the return transfer line 7b, and the return transfer line 7b returns the workpiece loading fixture to the loading platform 111 at the loading position 11. The first platform lifting mechanism 112 drives the loading platform 111 to rise, enabling the workpiece loading fixture to return to the initial position and waiting for the loading and installation of the next workpiece to be cleaned.

[0105] In addition, for the surge cleaning chamber 2, the spray cleaning chamber 3, and the rinsing chamber 4, the generated sewage will flow into their respective corresponding water collecting basins. The sewage in the water collecting basins will flow towards the water inlet 911a of the water storage tank 91, and after filtering the residues through the slag filtering net 911b, it will flow into the sedimentation chamber 911. The sedimentation chamber 911 and the water storage chamber 912 are connected through the communication port 913a at the bottom of the partition plate 913. Therefore, the liquid levels of the sedimentation chamber 911 and the water storage chamber 912 are flush. The oil layer in the sewage will float on the liquid surface of the sedimentation chamber 911, effectively reducing the inflow of the oil in the sewage into the water storage chamber 912, thereby further playing a filtering role. A slag blocking plate 914 is provided at the communication port 913a at the bottom of the partition plate 913, so that the sewage sediment in the water storage tank 91 mainly settles in the sedimentation chamber 911, further reducing the entry of sediments into the water storage chamber 912.

[0106] Finally, the sewage in the water storage chamber 912 of the water storage tank 91 is heated by the reused water heating pipe 915, then suctioned by the sewage pump 92, filtered again by the sewage filter 93, and then flows back into the water pipes corresponding to the surge cleaning chamber 2, the spray cleaning chamber 3, and the rinsing chamber 4, and is sprayed out by the spray nozzles of the corresponding spray rows, realizing the filtration and reuse of the sewage.
