Specifically, when the tool carrier is transported to the interior of the cleaning chamber and stops, but passes the predetermined position, the return drive mechanism drives the drive shaft to rotate, so that the drive shaft drives the return member to return the tool carrier. When the tool carrier reverses flow beyond the predetermined position, the over-return check member blocks the tool carrier from continuing to reverse flow, thereby preventing the tool carrier from over-returning. In addition, it ensures that the tool carrier is in the predetermined position when it stops inside the cleaning chamber, and achieves precise positioning of the tool carrier.

[0036] In detail, the tool carrier flows into the cleaning chamber along the transmission direction. When the tool carrier reaches the position of the over-check dial, the tool carrier will hit the over-check block of the over-check dial. The one-way inclined top surface of the over-check block is then compressed, so that the over-check block and the one-way inclined top surface are buried in the installation accommodating groove, so that the tool carrier can flow through without being blocked; otherwise, the end of the over-check dial close to the one-way inclined top surface will jam the tool carrier to prevent the tool carrier from over-flowing.

[0088] like Figures 1 to 15 As shown, in an embodiment of the present invention, a multi-station combined cleaning device is provided, comprising a loading station 11, a surge cleaning chamber 2, a first compartment 13, a spray cleaning chamber 3, a second compartment 14, a rinsing chamber 4, an air drying chamber 5, a vacuum drying chamber 6, and a unloading station 12, which are arranged in a transverse order. Furthermore, the device also comprises a tool and a main transmission mechanism 7 for transporting the tool. Among them:

[0089] The loading station 11 is equipped with a loading platform 111 and a first platform lifting mechanism 112 for driving the loading platform 111 to rise and fall. The loading platform 111 is provided with a loading conveyor mechanism 113. The loading conveyor mechanism 113 on the loading platform 111 is used to transport tools from the loading platform 111 into the surge cleaning chamber 2, specifically to the surge roller 221a on the surge conveyor mechanism 221.

[0090] The surge cleaning chamber 2 is provided with a surge water tank 21, a surge platform 22, a surge lifting mechanism 23 and a surge cleaning mechanism 24. The surge lifting mechanism 23 is used to lift the surge platform 22 so that the surge platform 22 can be immersed in the interior of the surge water tank 21 or even the bottom. The surge platform 22 includes a surge transmission mechanism 221 for transporting tools and equipment in and out of the surge cleaning chamber 2. The surge transmission mechanism 221 includes a plurality of surge rollers 221a capable of carrying tools and equipment 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 having multiple spray nozzles and a first air blowing row 242 having multiple air blowing nozzles. The first spray row 241 and the first air blowing row 242 are both located in the surge water tank 21. The surge water tank 21 is filled with water, and the workpiece is immersed in the water during cleaning. The first spray row 241 sprays, and the first blowing row 242 blows air, thereby forming bursting and rolling water bubbles in the water, thereby achieving surge cleaning of the workpiece. Detergent is generally added during the surge cleaning process.

[0091] The conveyor chain 71 of the main transmission mechanism 7 sequentially passes through the first compartment 13, the spray cleaning chamber 3, the second compartment 14, the rinsing chamber 4, and the air-drying chamber 5. The main transmission mechanism 7 is used to transport tools and equipment from the first compartment 13 to the air-drying chamber 5. The main transmission mechanism 7 includes two groups arranged in parallel, each group including a conveyor chain 71, a plurality of conveyor rollers 72 distributed on the conveyor chain 71, and a main sprocket 73 for driving the conveyor chain 71. The tools and equipment are transported along the conveyor rollers 72 of the two groups of conveyor chains 71. The surge cleaning chamber 2, the first compartment 13, the spray cleaning chamber 3, the second compartment 14, the rinsing chamber 4, and the air-drying chamber 5 are all equipped with front-to-back lifting doors. These lifting doors are used for the entry and exit of tools and equipment, while also sealing the chamber to reduce noise and water spillage. The lifting doors can be raised and lowered by a cylinder.

[0092] The spray cleaning chamber 3 is equipped with a spray cleaning mechanism 31 for spray cleaning the workpiece and a spray lifting mechanism 32 for raising and lowering the spray cleaning mechanism 31. Detergent is generally added 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.

[0093] The rinsing chamber 4 is equipped with a rinse-cleaning mechanism 41 for rinsing workpieces and a rinse-lifting mechanism 42 for raising and lowering the rinse-cleaning mechanism 41. Detergent is generally not added during the rinsing process. However, if cleaning iron or other rust-prone workpieces, a rust inhibitor may be added as needed. The rinse-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.

[0094] 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. By blowing hot air in the air-drying chamber 5, large areas of water stains on the surface of the workpiece are blown away and large-area air 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 the fourth air blowing row 513, and the air heating element 512 is used to heat 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, wherein the electric heating element is installed in the metal shell and is separated from the air flow by insulating material to prevent short circuit and electric shock. The air pipe leading out of the air tank 511 is connected to the metal shell, and the cold air in the air tank 511 is introduced into the area 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 nozzle on the fourth air blowing row 513.

[0095] The vacuum drying chamber 6 is equipped with a vacuum drying mechanism 61 and a vacuum conveying mechanism 62. The vacuum drying mechanism 61 heats the workpiece, evaporating any water on the workpiece surface. The vacuum pump 615 then draws the evaporated water into the vacuum drying chamber 6, thereby drying the workpiece. The vacuum conveying mechanism 62 transports tools and equipment into and out of the vacuum drying chamber 6. The vacuum drying chamber 6 effectively dries any water remaining in the workpiece's fine pores, deep holes, or blind spots. The vacuum drying mechanism 61 includes a drying heating tube 611, a vacuum cover 612, a vacuum lifting mechanism 613, a moisture filter 614 and a vacuum pump 615. The drying heating tube 611 and the vacuum cover 612 are arranged inside the vacuum drying chamber 6. The drying heating tube 611 can be an infrared heating tube or an ordinary 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 the vacuum cover 612 so that when the vacuum cover 612 descends, it can cover the infrared heating tube and the ordinary heating tube and form an enclosed space. The enclosed space formed by the vacuum cover 612 is formed into a negative pressure vacuum through the suction of the vacuum pump 615, thereby extracting the moisture heated into water vapor inside to achieve vacuum drying. Specifically, vacuum pump 615 is connected to moisture filter 614, which is in turn connected to vacuum hood 612. When air and moisture are drawn from vacuum hood 612, most of the moisture is first filtered out through moisture filter 614 via a conduit, preventing excessive moisture from directly entering vacuum pump 615 and damaging it. Vacuum transmission mechanism 62 includes a vacuum chamber sprocket and a vacuum chamber chain driven by the vacuum chamber sprocket. Vacuum transmission mechanism 62 can also employ the same structure as main transmission mechanism 7. Alternatively, vacuum transmission mechanism 62 can be an extension of main transmission mechanism 7, meaning that main transmission mechanism 7 is also used to transport tools in and out of vacuum drying chamber 6.

[0096] The unloading station 12 is equipped with a loading platform 121 and a second loading platform lifting mechanism 122 for driving the unloading platform 121 upwards and downwards. A loading conveyor mechanism 123 is installed on the loading platform 121. The loading conveyor mechanism 123 on the loading platform 121 is used to transport tools and equipment to the return conveyor line 7b. A rear conveyor line 7a is also provided between the vacuum drying chamber 6 and the unloading station 12.

[0097] A reflux transmission line 7b is also provided between the bottom of the unloading position 12 and the bottom of the loading position 11. The reflux transmission line 7b is located at the bottom of the main transmission line. The reflux transmission line 7b is used to return the tooling on the unloading platform 121 of the unloading position 12 to the loading platform 111 of the loading position 11.

[0098] In one embodiment, the spray row is composed of a spray plate with several flow channels inside. A spray nozzle is set at each flow channel. Water from the water pipe enters the spray plate, is divided into several flow channels, and is then sprayed out by the spray nozzle.

[0099] 2. In one embodiment, Figure 1 、 Figure 6 、 Figures 10 to 12As shown, it also includes a tool positioning 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 tool positioning mechanism 8a, the rinsing tool positioning mechanism 8b, and the air drying tool positioning mechanism 8c. The positioning mechanism 8 includes a drive shaft 81, a return member 82 whose one end is synchronously rotated and arranged on the drive shaft 81, and a return drive mechanism 83 for driving the drive shaft 81 to rotate. The return member 82 is provided with a rubber pad 821 at the end away from the drive shaft 81. The drive shaft 81 is arranged under the top of the conveyor chain 71, specifically passing between the top and bottom of the conveyor chain 71 and arranged vertically on the conveyor chain 71. A drive arm 84 is provided 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 rotates the drive arm 84, causing the drive shaft 81 and the return member 82 to rotate synchronously, thereby reversing the tool. The positioning mechanism 8 also includes an over-check member 85. The over-check member 85 is closer to the loading position 11 than the return member 82. That is, the direction in which the over-check member 85 points toward the drive shaft 81 is the transmission direction of the conveyor chain 71. The distance between the over-check member 85 and the drive shaft 81 is greater than the length of the tool along the transmission direction of the transmission chain, allowing the tool to be accommodated between the over-check member 85 and the drive shaft 81. The over-return check member 85 includes a non-return mounting seat 851 and an over-return check block 852. The non-return mounting seat 851 is provided with a mounting groove 851a. The bottom of the mounting groove 851a is provided with a spring mounting port 851b. The spring mounting port 851b is provided with a return spring 853. The over-return check block 852 has a hinge portion 852a and a non-return portion 852b. The top of the non-return portion 852b is provided with a one-way inclined top surface 852b1. The one-way The inclined top surface 852b1 is arranged obliquely upward in the direction of the drive shaft 81, and the over-return check block 852 is hinged and buried in the installation groove 851a. Specifically, the hinged portion 852a of the over-return check block 852 is hinged to the side of the installation groove 851a away from the return spring 853, and the return spring 853 presses against the bottom of the check portion 852b, so that all or part of the one-way inclined top of the check portion 852b extends out of the installation groove 851a. The over-return check dial 85 can realize one-way transmission of the tool and the carrier. When the tool and the carrier are pushed back by the return dial member 82, if the return distance exceeds the predetermined stroke, the non-return portion 852b of the over-return check dial 85 can play a non-return role, preventing the return dial member 82 from pushing the tool and the carrier back too far, thereby enabling the tool and the carrier to be accurately positioned between the return dial member 82 and the over-return check dial 85, completing the preset positioning of the tool and enabling the hole position of the workpiece on the tool and the spray nozzle and the blow nozzle to be aligned, thereby making it more conducive to fully cleaning the workpiece and reducing the occurrence of local or blind corners that cannot be cleaned due to insufficient coverage of the spray nozzle and the blow nozzle.

[0100] Specifically, the operator pre-positions and calibrates the tool holder in the cleaning chamber according to the specifications of the workpiece to be cleaned. Specifically, the operator places the tool holder between the corresponding return member 82 and the over-return check member 85 in the cleaning chamber to determine the predetermined position. The operator then aligns the spray nozzles on the corresponding spray row and the air nozzles on the air row in the cleaning chamber with the deep or fine holes of the workpiece to be cleaned at the predetermined position. After calibration, when the workpiece is cleaned, before the tool holder flows into the cleaning chamber and stops for cleaning, a sensing element such as a photoelectric switch or a grating identifies whether the tool holder is in the predetermined position. If the tool holder is transported past the predetermined position by the conveyor chain 71 and conveyor roller 72, the return member 82 returns the tool holder to the predetermined position. If the force of the return member 82 is too great, the over-return check member 85 stops the tool holder from flowing backwards to prevent it from flowing too far. In this way, it can be ensured that the tool holder is in a predetermined position when staying inside the cleaning chamber, thereby achieving accurate positioning of the tool holder.

[0101] 3. In another embodiment, Figure 1 、 Figures 13 to 15 As shown, the surge cleaning chamber 2, the spray cleaning chamber 3 and the rinsing chamber 4 are all provided with water collection basins, which are respectively a surge water collection basin, a spray water collection basin and a rinse water collection basin. Each water collection basin is correspondingly matched with a sewage reuse mechanism 9, which are respectively a surge sewage reuse mechanism 9a, a spray sewage reuse mechanism 9b and a rinse sewage reuse mechanism 9c. The sewage reuse mechanism 9 includes a water tank 91, a sewage pump 92 and a sewage filter 93. A partition 913 is provided inside the water tank 91 to divide the interior of the water tank 91 into a sedimentation chamber 911 and a water storage chamber 912. A water inlet 911a connected to the water collection basin is opened at the top of the sedimentation chamber 911, and the water inlet 911a is provided with a filter residue net 911b. A connecting port 913a connected to the sedimentation chamber 911 and the water storage chamber 912 is opened at the bottom of the partition 913. A slag baffle 914 adjacent to the connecting port 913a is provided inside the water storage chamber 912.

[0102] Working process:

[0103] The workpiece to be cleaned is mounted on the tool carrier of the loading platform 111 located at the loading position 11. The first platform lifting mechanism 112 drives the loading platform 111 to rise, thereby driving the tool carrier to a predetermined height.

[0104] The loading and conveying mechanism 113 is activated to transport the workpiece from the loading platform 111 to the surge platform 22 in the surge cleaning chamber 2. The surge water tank 21 contains sufficient water. The surge lifting mechanism 23 drives the surge platform 22 down to the bottom of the surge water tank 21, thereby completely immersing the surge platform 22 in water. Then, the surge cleaning mechanism 24 performs surge cleaning on the workpiece on the workpiece.

[0105] After the surge cleaning is completed, the surge carrier 22 rises, and the surge transmission mechanism 221 transports the tool on the surge carrier 22 to the transmission chain 71 of the main transmission mechanism 7. The transmission chain 71 transports the tool through the first compartment 13 and the spray cleaning chamber 3 until the tool is sent to the positioning mechanism 8 of the spray cleaning chamber 3. Specifically, the tool is placed between the return dial 82 and the over-check dial 85 of the positioning mechanism 8, thereby completing the positioning of the tool in the spray cleaning chamber 3, and then the spray lifting mechanism 32 drives the spray cleaning mechanism 3 1 descends, causing the spray cleaning mechanism 31 to spray clean the workpiece on the tool carrier; wherein, the positioning mechanism 8 is used to enable the tool carrier to accurately stay at a predetermined position in the spray cleaning chamber 3, that is, between the return dial 82 and the over-check dial 85 of the positioning mechanism 8, so that the spray nozzles on the second spray row 311 and the air blowing nozzles on the second air blowing row 312 can be aligned with the corresponding holes or surfaces on the tool carrier, respectively, thereby improving the coverage and efficiency of the spray cleaning and effectively avoiding the problem of inadequate spray cleaning of blind corners and blind holes;

[0106] After the spray cleaning is completed, the spray cleaning mechanism 31 rises to avoid blocking the tool carrier, so that the tool carrier can be transported out of the spray cleaning chamber 3 by the main transmission mechanism 7, and pass through the second compartment 14 and the rinse chamber 4 until it enters the positioning mechanism 8 of the rinse chamber 4. Specifically, the tool carrier is placed between the return dial 82 and the over-check dial 85 of the positioning mechanism 8, thereby completing the positioning of the tool carrier in the rinse chamber 4, and then the rinse lifting mechanism 42 drives the rinse cleaning mechanism 41 to descend, so that the rinse cleaning mechanism The structure 41 rinses the workpiece on the tool carrier; wherein, the positioning mechanism 8 is used to enable the tool carrier to accurately stay at a predetermined position in the rinsing chamber 4, that is, between the return dial 82 and the over-return check dial 85 of the positioning mechanism 8, so that the spray nozzles on the third spray row 411 and the blowing nozzles on the third blowing row 412 can be aligned with the corresponding holes or surfaces on the tool carrier, respectively, thereby improving the coverage and efficiency of rinsing and cleaning, and effectively avoiding the problem of blind corners and blind holes not being rinsed properly;

[0107] After rinsing is completed, the rinsing and cleaning mechanism 41 rises to avoid blocking the workpiece carrier, so that the workpiece carrier can be transported out of the rinsing chamber 4 by the main transmission mechanism 7 and enter the air-drying chamber 5 until it enters the adjusting mechanism 8 of the air-drying chamber 5, specifically, the workpiece carrier is placed between the return dial 82 of the adjusting mechanism 8 and the over-check dial 85, thereby completing the positioning of the workpiece carrier in the air-drying chamber 5, and then the air-drying lifting mechanism 52 drives the hot-air drying mechanism 51 to descend, so that the hot-air drying mechanism 51 performs hot-air drying on the workpiece carrier; wherein, the adjusting mechanism 8 is used to enable the workpiece carrier to accurately stay in the predetermined position in the air-drying chamber 5, that is, between the return dial 82 and the over-check dial 85 of the adjusting mechanism 8, so that the air-drying air nozzles on the fourth blowing row 513 can be aligned with the corresponding holes or surfaces on the workpiece carrier, thereby improving the coverage area of the hot air blowing and the hot air drying efficiency, and effectively avoiding the problem of inadequate hot air drying in blind corners and blind holes;

[0108] After the hot air drying is completed, the hot air drying mechanism 51 rises to avoid blocking the tool and enables the tool to be transported out of the drying chamber 5 by the main conveying mechanism 7 until it enters the vacuum drying chamber 6. The vacuum lifting mechanism 613 drives the vacuum cover 612 to descend and cover the tool. The drying heating tube 611 heats up to evaporate the residual water stains in the pores, deep holes or dead corners of the tool. The vacuum pump 615 starts to suck the air and evaporated water vapor in the vacuum cover 612. On the way, the air or water vapor enters the moisture filter 614 through the pipeline to filter the moisture, and then is pumped out by the vacuum pump 615.

[0109] After the vacuum drying is completed, the vacuum hood 612 rises, and the tool carrier is transported from the vacuum drying chamber 6 to the rear-end transmission line 7a, and is transported by the rear-end transmission line 7a to the unloading platform 121 of the unloading position 12. The operator then removes the cleaned workpiece from the tool carrier, and the second platform lifting mechanism 122 drives the unloading platform 121 to descend, thereby lowering the tool carrier, and the unloading transmission mechanism 123 on the unloading platform 121 transports the tool carrier from the unloading platform 121 to the reflux transmission line 7b, and the reflux transmission line 7b returns the tool carrier to the loading platform 111 of the loading position 11, and the first platform lifting mechanism 112 drives the loading platform 111 to rise, so that the tool carrier returns to the initial position, waiting for the next workpiece to be cleaned to be loaded and installed.

[0110] 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 collection basins, and the sewage in the water collection basins will flow to the water inlet 911a of the water storage tank 91, and after filtering the residue through the filter net 911b, it will flow into the sedimentation chamber 911. The sedimentation chamber 911 and the water storage chamber 912 are connected through the connecting port 913a at the bottom of the partition 913. Therefore, the liquid levels of the sedimentation chamber 911 and the water storage chamber 912 are flush, and the oil layer in the sewage will float on the liquid surface of the sedimentation chamber 911, effectively reducing the oil in the sewage from flowing into the water storage chamber 912, thereby further playing a filtering role; and the connecting port 913a at the bottom of the partition 913 is provided with a slag baffle 914, so that the sewage sediment in the water storage tank 91 is mainly settled in the sedimentation chamber 911, further reducing the sediment from entering the water storage chamber 912;

[0111] Finally, the sewage in the water storage chamber 912 of the water tank 91 is heated by the reuse water heating pipe 915, then sucked by the sewage pump 92, filtered again by the sewage filter 93, and then returned to the corresponding matching water pipes of the surge cleaning chamber 2, spray cleaning chamber 3 and rinse chamber 4, and sprayed out by the corresponding spray nozzles of the spray row, thereby filtering and reusing the sewage.
