Each first cleaning member 98 can include a holding plate 982 coupled to an end portion of the connecting plate 927 and an air knife 984 coupled to an end portion of the holding plate 982. The holding plate 982 can be located at a side of the connecting plate 927 away from the slide block 925 and positioned adjacent to the second belt 36. The air knife 984 can be coupled to an air source (not shown) and include an opening (not shown) toward the second belt 36. The second cleaning members 93 can be installed at two sides of the bottom plate 14 and positioned adjacent to the second belt 36. The second cleaning members 93 can be coupled to the air source and include an opening (not shown) toward the second belt 36. In at least one embodiment, the second cleaning members 93 can be blowpipes and made from flexible materials, so that the second cleaning members 93 can be deformed in shape. A number of the second cleaning members 93 can be four. In at least one embodiment, a number of the second cleaning members 93 can be one, two, three, or more than four. The second cleaning members 93 can be installed on the side plates 16 of the fixed frame 10 so long as the openings of the cleaning members 93 extend toward the second belt 36.
FIG. 3 illustrates the positioning of the workpiece 300. The workpiece 300 can be transported from a production line (not shown) to the second belt 36 via the guide members 19. When the workpiece 300 touches the sensor 76, the controller can stop a rotation of the first drive member 32, so that the workpiece 300 is not moving. The two positioning members 50 can push the workpiece 300 to move toward a guide member 19, the workpiece 300 can thereby be clamped between the positioning members 50 and the guide member 19.
For cleaning the workpiece 300, the air knives 984, coupled to the air source, can be employed. The cleaning drive member 95 can drive the first belt 97 to move back and forth along the second belt 36, the air knives 984 can thus move back and forth along the second belt 36 above the workpiece 300, so that surface pollutants of the workpiece 300 can be removed. The second cleaning members 93 can direct air toward a bottom surface of the workpiece 300, to remove other surface pollutants. In this way, the first cleaning members 98 and the second cleaning members 93 can clean the workpiece 300 from different angles. The positioning members 50 can move away from the workpiece 300 after the workpiece 300 is cleaned, and the second drive member 72 can drive the sensor 76 to move away from the workpiece 300. The first drive member 32 can drive the second belt 36 to transport the workpiece 300 to a next process.
In at least one embodiment, the tracks 124 and the slide blocks 925 can be omitted so long as the first belt 97 drives the first cleaning member 98 to move back and forth along the second belt 36. The connecting members 17, the support members 18, and the guide members 19 can be omitted, and the positioning members 50, the first drive member 32 and the rotator member 34 can be installed on the side plates 16. The fixing member 94 and the connecting plate 927 can be omitted, and the first cleaning members 98 can be connected directly to the first belt 97. All of the positioning members 50, the stopper assemblies 70, and the second cleaning members 93 can be omitted so long as access to all pollutants on the workpiece 300 can be achieved.
While the present disclosure has been described with reference to particular embodiments, the description is illustrative of the disclosure and is not to be construed as limiting the disclosure. Therefore, those of ordinary skill in the art can make various modifications to the embodiments without departing from the scope of the disclosure, as defined by the appended claims.
