Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0023] Please refer to Figures 1 to 2 One embodiment of the present application illustrates a workpiece cleaning mechanism for a heat treatment production line. The workpiece cleaning mechanism includes a cleaning assembly and an oil-water separation assembly. The cleaning assembly is used to clean the workpiece, while the oil-water separation assembly is used to remove quenching oil and impurities from the cleaning assembly to ensure that the cleaning fluid in the cleaning assembly achieves the desired cleaning effect on the workpiece and prevent the quenching oil from affecting subsequent tempering.

[0024] The cleaning assembly includes a degreasing tank 11, a dephosphorization tank 12 and a cleaning tank 13 connected in sequence, wherein the degreasing tank 11 is connected to the rear end of the quenching tank; the degreasing tank 11, the dephosphorization tank 12 and the cleaning tank 13 are filled with cleaning liquids with different functions, wherein the degreasing tank 11 is mainly used to remove the quenching oil on the surface of the workpiece. The workpiece needs to be phosphated before quenching to enhance rust resistance, but needs to be removed after quenching to avoid affecting subsequent processes. Therefore, the workpiece is dephosphorized by setting the dephosphorization tank 12. Dephosphorization can prevent unnecessary chemical reactions and corrosion, ensuring that the workpiece surface is smooth. Finally, by setting the cleaning tank 13, oxides, residues and other pollutants generated during the quenching process can be removed to ensure the cleanliness of the workpiece and reduce cross contamination between processes.

[0025] The oil-water separation assembly includes an oil-water separation module 20 disposed in the degreasing tank 11, the dephosphorization tank 12, and the cleaning tank 13. The oil-water separation module 20 includes an oil-absorbing float 21 disposed in each of the degreasing tank 11, the dephosphorization tank 12, and the cleaning tank 13, a power pump connected to the oil-absorbing float 21, and an oil-water separation unit connected to the power pump. The oil-water separation unit is conventional technology and will not be described in detail here.

[0026] In one embodiment, two sets of oil-water separation modules 20 are provided in the degreasing tank 11, with one set each in the dephosphorization tank 12 and the cleaning tank 13. During the cleaning process, grease removed from the workpiece in the degreasing tank 11 floats on the surface of the cleaning fluid. Grease easily absorbs impurities, and during the transfer of the workpiece, it is easily contaminated with grease again and carried over to the next cleaning step, thereby affecting the subsequent cleaning effect. Therefore, by providing oil-water separation modules 20 in the degreasing tank 11, the dephosphorization tank 12, and the cleaning tank 13, grease on the surface of the cleaning fluid is recovered, thereby preventing grease from flowing with the workpiece during the cleaning process. Since the degreasing tank 11 is the main collection point for grease, two sets of oil-water separation modules 20 are provided in the degreasing tank 11, and one set is provided in each of the remaining cleaning steps. This allows for a step-by-step recovery of grease and impurities, thereby ensuring the cleanliness of the cleaning fluid surface.

[0027] In one embodiment, the power pump is a perfluorinated diaphragm pump. The operating principle of a perfluorinated diaphragm pump primarily relies on the movement of a diaphragm to generate fluid suction and discharge. When the diaphragm moves downward, the pressure within the liquid chamber decreases, causing fluid to flow into the liquid chamber through the inlet and outlet valves. When the diaphragm moves upward, the pressure within the liquid chamber increases, causing the fluid to be discharged through the outlet valve. The periodic movement of the diaphragm continuously discharges the quenching oil from the quenching assembly. This is prior art and will not be described in detail here.

[0028] In one embodiment, the workpiece cleaning mechanism further includes a conveying assembly for conveying the workpiece, the conveying assembly comprising a first conveying assembly disposed between the degreasing tank 11 and the dephosphorization tank 12, and a second conveying assembly disposed between the dephosphorization tank 12 and the cleaning tank 13. The conveying assembly sequentially conveys the workpiece between the degreasing tank 11, the dephosphorization tank 12, and the cleaning tank 13, thereby achieving automated cleaning and reducing manual intervention.

[0029] In one embodiment, the first conveyor assembly includes a first mesh conveyor belt 31 and a first power element 32 for driving the mesh conveyor belt. One end of the first mesh conveyor belt 31 is positioned within the degreasing tank 11, and the other end is positioned above the dephosphorization tank 12. The first power element 32 is a motor. By tilting the mesh conveyor belt, the cleaning liquid on the workpieces can be returned to the corresponding degreasing tank 11 via the mesh conveyor belt during the conveying process, thereby reducing large-scale cross-contamination of the cleaning liquid between the degreasing tank 11 and the dephosphorization tank 12.

[0030] In one embodiment, the second conveyor assembly includes a second mesh conveyor belt 33 and a second power element 34 for driving the conveyor belt. One end of the second mesh conveyor belt 33 is positioned within the dephosphorization tank 12, and the other end is positioned above the cleaning tank 13. The second power element 34 is a motor. By tilting the mesh conveyor belt, the cleaning liquid on the workpieces can be dropped back into the corresponding degreasing tank 11 via the mesh conveyor belt during the conveyor belt's transportation, thereby reducing large-scale cross-contamination of the cleaning liquid between the dephosphorization tank 12 and the cleaning tank 13.

[0031] In one embodiment, a filter is provided at the oil inlet of the oil-absorbing float 21. This prevents large impurities within the cleaning assembly from entering the oil-water separation process, thereby preventing damage to the oil-water separation module 20 and extending its service life. Preferably, the filter is provided within the oil-absorbing float 21 to collect large impurities within the float 21, thereby improving the cleanliness of the cleaning liquid surface.

[0032] In one embodiment, a filter is provided between the oil-absorbing float 21 and the power pump. The filter provides secondary filtration of the oil-absorbing float 21 to further remove impurities from the oil-water mixture. The filter is conventional and will not be described in detail here.

[0033] The present application sequentially arranges a degreasing tank, a dephosphorization tank and a cleaning tank downstream of the quenching tank to degrease, dephosphorize and clean the workpiece treated in the quenching tank, and uses a variety of cleaning methods to clean the workpiece to improve the cleaning effect of the workpiece. An oil-water separation module is separately arranged in the degreasing tank, the dephosphorization tank and the cleaning tank to separate and collect the quenching oil in the degreasing tank, the dephosphorization tank and the cleaning tank to avoid the quenching oil affecting the subsequent tempering process of the workpiece, thereby improving the tempering quality of the workpiece.

[0034] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
