[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] like Figures 1 to 2 As shown, the cleaning conveyor line of the present invention is used to transport parts to be cleaned fixed on a pallet. The cleaning conveyor line includes: a loading area 10, located at the entrance end of the cleaning conveyor line, receiving and placing pallets sent in by external transportation equipment, the pallets carrying parts to be cleaned; a first cleaning conveyor area 20, connected to the loading area 10, transferring the parts to be cleaned to a predetermined cleaning station; a second cleaning conveyor area 30, located on one side of the first cleaning conveyor area 20, receiving parts that have been cleaned by the first cleaning conveyor area 20; wherein, a plurality of translational roller tracks are provided between the first cleaning conveyor area 20 and the second cleaning conveyor area 30 to transfer the parts to be cleaned between the two conveyor areas; and an unloading area 40, located at the end of the first cleaning conveyor area 20, outputting the cleaned parts to an external production line.

[0030] As can be seen, this invention automates the cleaning process by setting the cleaning conveyor line into a loading area, a first cleaning conveyor area, a second cleaning conveyor area, and an unloading area. This reduces manual intervention and improves productivity and work safety. The cleaning conveyor line of this invention is divided into a first cleaning conveyor area and a second cleaning conveyor area, which can sequentially perform different types of deep cleaning on parts, ensuring the comprehensiveness and efficiency of the cleaning. Through the coordinated use of the translation roller, the workpiece is quickly and accurately transferred between different workstations, shortening the cleaning cycle, improving the production line cycle time, and greatly solving the problem of low efficiency in existing cleaning conveyor lines.

[0031] like Figure 1As shown, the cleaning conveyor line also includes: an ultrasonic cleaning zone 50, located on the side of the cleaning conveyor line near the loading area 10, equipped with an ultrasonic generator to remove oil stains from the surface of the parts to be cleaned; a high-pressure spray zone 60, equipped with a high-pressure spray component and a carrying component, where the high-pressure spray component sprays high-pressure cleaning fluid onto the parts as the carrying component rotates the parts fixed on the tray; and a drying zone 70, located on the side of the cleaning conveyor line near the unloading area 40, equipped with at least one blower to quickly dry the cleaned parts. The ultrasonic cleaning zone 50 and the high-pressure spray zone 60 are sequentially located on one side of the first cleaning conveyor zone 20, and the drying zone 70 is located on the first cleaning conveyor zone 20. The combined ultrasonic and high-pressure spray cleaning effectively removes oil stains and impurities from the surface and interior of the parts, followed by rapid drying to ensure dryness. This method is suitable for production processes requiring deep cleaning and rapid drying, such as the cleaning of engine parts. This combination of deep cleaning and quick drying not only removes stubborn oil and impurities but also quickly restores parts to a dry state, avoiding potential corrosion from moisture and effectively preventing rust after cleaning.

[0032] Preferably, the cleaning conveyor line further includes: a first connecting branch 80, one end of which is connected to the ultrasonic cleaning zone 50, and the other end of which is connected to the first cleaning conveyor zone 20, conveying the parts to be cleaned to the ultrasonic cleaning zone 50; and a second connecting branch 90, one end of which is connected to the high-pressure jet zone 60, and the other end of which is connected to the first cleaning conveyor zone 20, conveying the parts to be cleaned to the high-pressure jet zone 60. A rotary table 100 is provided at the connection point between the first connecting branch 80, the second connecting branch 90, and the first cleaning conveyor zone 20. The rotary table 100 is rotatably configured and includes a rotating part and a linear conveying section located above the rotating part. The linear conveying section carries the tray, drives the tray to move, and rotates with the rotating part. The rotary table design allows the cleaning line to flexibly switch cleaning processes, improving the adaptability and efficiency of the production line. It is suitable for production environments where the cleaning process needs to be adjusted according to different part types. The cleaning line can adjust the cleaning sequence and method according to the characteristics of different parts, improving the accuracy and efficiency of cleaning and reducing resource waste during the cleaning process.

[0033] Specifically, the second cleaning and conveying zone 30 further includes: a first conveying branch 310, located on the side of the first cleaning and conveying zone 20 away from the ultrasonic cleaning zone 50, and arranged along the extending direction of the first cleaning and conveying zone 20; and a second conveying branch 320, located on the side of the first conveying branch 310 away from the first cleaning and conveying zone 20, and arranged along the extending direction of the first conveying branch 310. A laser cleaning zone 321 is provided on the second conveying branch 320, and at least one laser emitter is provided within the laser cleaning zone. The laser emitter is used to generate a laser beam to remove rust from the surface of the part to be cleaned. The laser cleaning zone can precisely remove rust from the surface of parts, maintaining the original precision and surface quality of the parts. It is suitable for cleaning precision mechanical parts with extremely high surface cleanliness requirements. For some precision mechanical parts, such as engine blades and turbine disks in the aerospace field, it can effectively remove minute rust and damage from the surface, ensuring the service life and safety of the parts, and reducing the cost and difficulty of subsequent processing and assembly.

[0034] like Figure 1 As shown, the second cleaning conveying area 30 further includes: a first translational conveying roller 110, at least a portion of the first conveying branch 310 being connected to the first translational conveying roller 110, and a second conveying branch 320 disposed on one side of the first translational conveying roller 110, through which the laser-cleaned parts are transferred to the first conveying branch 310. The design of the first translational conveying roller allows for a smooth transition of parts during multi-stage cleaning processes, reducing damage to parts caused by sudden mechanical impacts or vibrations, improving the integrity and service life of the parts, and is suitable for complex parts requiring multiple cleaning processes.

[0035] Optionally, the cleaning conveyor line further includes a second translational conveyor 120, which is located near the unloading area 40. At least a portion of the first cleaning conveyor area 20 is connected to the second translational conveyor 120. A first conveying branch 310 and a second conveying branch 320 are spaced apart along the extension direction of the second translational conveyor 120 to transfer the parts to be cleaned in the first cleaning conveyor area 20 to the second cleaning conveyor area 30. The design of the second translational conveyor makes the material flow within the cleaning line more efficient, allowing for rapid response to changes in production demands, reducing production line downtime, and improving overall production efficiency.

[0036] In an embodiment of the present invention, when the part to be cleaned requires laser cleaning, the part to be cleaned is transferred from the second translational conveying roller 120 to the second conveying branch 320; when the part to be cleaned does not require laser cleaning, the part to be cleaned is transferred from the second translational conveying roller 120 to the first conveying branch 310.

[0037] Optionally, the cleaning conveyor line further includes a third translational conveyor 130, which is located on the side near the loading area 10. At least a portion of the first cleaning conveyor area 20 is connected to the third translational conveyor 130. A first conveying branch 310 is located on one side of the third translational conveyor 130, transferring the parts that have been cleaned in the second cleaning conveyor area 30 to the first cleaning conveyor area 20. The third translational conveyor allows the cleaning line to form a closed loop. For parts that need to be cleaned again or undergo quality inspection, they can quickly return to the cleaning process, improving the accuracy and reliability of cleaning. This is suitable for production processes that require multiple cleanings and quality control, such as in the field of precision instrument manufacturing, where it is used to clean high-precision optical components to ensure the optical performance and operational stability of the components, meeting the high requirements of precision instruments.

[0038] like Figure 1 and Figure 2 As shown, the cleaning conveyor line of the present invention also includes a cleaning device, which includes: a feeding roller 1, which is set at the inlet end of the automatic cleaning device and is used to transfer the parts to be cleaned on the tray to a preset cleaning position; a discharging roller 2, which is set at the outlet end of the automatic cleaning device and is arranged parallel to the feeding roller 1, and outputs the dried parts from the automatic cleaning device; a pre-cleaning station 3, which is set at the end of the feeding roller 1, and performs preliminary cleaning on the parts to be cleaned to remove mud and dirt from the surface of the parts to be cleaned; and multiple cleaning branches 4, which are spaced apart between the feeding roller 1 and the discharging roller 2 along the extension direction of the feeding roller 1 to form multiple intervals for deep cleaning of the parts to be cleaned; wherein, each cleaning branch 4 includes a cleaning station 41 and a drying station 42, and the drying station 42 is set on the side of the cleaning station 41 away from the feeding roller 1, and dries the cleaned parts. The integrated design of this cleaning equipment enables full automation of the process from initial cleaning to deep cleaning and then to rapid drying, greatly improving cleaning efficiency and quality. It is suitable for the rapid turnover needs of large-scale industrial production, such as in automobile manufacturing production lines, where it can achieve continuous and rapid parts cleaning, ensuring the efficient operation of the production line, improving overall production efficiency and reducing costs.

[0039] In this embodiment, the cleaning station further includes two cleaning components, each of which includes an immersion tank, an ultrasonic cleaning tank, and a spray tank connected in sequence. Each cleaning component is used to clean parts of different materials or sizes, such as aluminum alloy parts and cast iron parts, to ensure that each part can get the best cleaning effect. This allows the equipment to process multiple types of parts at the same time, improving the utilization rate of the equipment, reducing waiting time, and greatly improving the efficiency of the production line.

[0040] Preferably, the cleaning equipment further includes: multiple conveyor rollers 5, which are arranged one-to-one within multiple cleaning branch paths 4, and are located between the cleaning station 41 and the unloading roller 2 for transporting the cleaned parts; a re-washing station 6, with a re-washing station 6 located on one side of at least one conveyor roller 5, situated within the interval formed by the corresponding multiple cleaning branch paths 4, and between the cleaning station 41 and the drying station 42, for manual re-washing of parts that do not meet the standards; wherein, the drying station 42 is located within the multiple conveyor rollers 5. The introduction of the re-washing station provides a timely solution for abnormal situations during the cleaning process, avoids product quality problems caused by incomplete cleaning, improves the reliability of cleaning and product quality, ensures that all parts meet the cleaning standards, and is suitable for production environments with strict requirements for cleaning quality.

[0041] Preferably, the cleaning equipment is located on one side of the first cleaning conveying area 20, close to the unloading area 40. A rotary table 100 is provided at the connection between the loading roller 1 and unloading roller 2 of the cleaning equipment and the first cleaning conveying area 20. The rotary table 100 is rotatably mounted and includes a rotating part and a linear conveying section located above the rotating part. The linear conveying section carries the pallet, moves the pallet, and rotates with the rotating part. This rotary table design not only achieves efficient material flow between the cleaning equipment and the conveyor line, but also allows the cleaning equipment to connect to the conveyor line at various angles through the rotating part, improving the layout flexibility of the production line and making it suitable for production environments with limited space or requiring optimized production line layout.

[0042] In embodiments of the present invention, the cleaning conveyor line is designed for workpieces of different sizes to improve cleaning efficiency, flexibility, and cleaning effect. Specifically, it includes:
