In specific implementation, the support frame 1 ensures the stability and the flatness of the whole cleaning device. The transverse moving mechanism 6 is used as an existing mature integrated part to drive the cleaning mechanism to transversely move, and the independent module design is adopted, so that the cleaning mechanism can be compatible with carrier plate assembly line type operation, rotary disc type operation and other operation modes. The dustproof and waterproof mop cover 8 is used for covering a water pipe and an electric wire used by a cleaning mechanism in the interior, and has a protection effect on the water pipe and the electric wire in the interior. Lifting module 3 adopts ripe electric lift mechanism, has ascending and descending function, can carry out at first keeping away a position to support plate, then can the height of electric regulation washing water sword and clean cylinder brush, ensures that the cleanliness factor of support plate reaches fine effect after wasing, goes up and down to adopt electric control, and the reaction is fast, operates steadily, and the precision of motion is high. Waterproof bottom plate 5 plays the connection regulatory action as the mounting plate of clean mechanism, ensures the harmony of whole device, and easy to assemble dismantles, and waterproof dustcoat 7 is also installed in waterproof bottom plate 5 outsidely. The waterproof outer cover 7 covers the cleaning parts in the cleaning mechanism and prevents water in the cleaning process from splashing outside the cutter. The first cleaning water jet 15 adopts high-pressure cleaning to primarily clean slurry and dust attached to the carrier plate, and the pressure of the cleaning water jet is adjustable between 10 kPa and 600 kPa. The cleaning solution used may be transparent liquid water, such as pure water, deionized water, distilled water, and organic solution, and the organic solution may be a release agent, and may also be diethylene glycol monobutyl ether as a diluent, and the cleaning solution is not particularly limited herein, and in other examples, the cleaning solution may also be opaque liquid, and will not be described herein too much since the water jet is a mature product application. The cleaning roller brush 13 is installed by a rotation screw, because the cleaning roller brush has a rotation function, if the rotation function is not required, the rotation screw can be tightened to prevent the cleaning roller brush from rotating. Cleaning roller brush 13 is after the washing of the water sword of the first time, the reuse cleaning roller brush is brushed the support plate once, with thick liquids and dust brush that the adhesive force is strong, cleaning roller brush's shape can be circular and can the rotation, rectangular shape, rectangular trapezoid and some other irregular polygons all can, the material of brush can be artificial fiber, for example nylon PA, polypropylene (PP) brush nylon, PBT, PET, plastics such as PVC silk and natural wools, the bristle, wool, horse hair, white palm etc. do not do specific designation here to the brush material. The second cleaning water knife 11 is used for cleaning the carrier plate accurately, and the cleaning pressure is adjustable between 10 kPa and 600 kPa. The sponge roller 17 that absorbs water prevents that the support plate from getting rid of water in other places in the motion process after the support plate washs and accomplishes, cleans the collection to support plate bottom drop of water. The squeeze roller 1902 is used for providing a radial extrusion force to the sponge cylinder 17 that absorbs water, because the sponge cylinder that absorbs water is in the wet state after absorbing the drop on the support plate, extrudes the water in the sponge cylinder that absorbs water through squeeze roller, and the effect is not good when the sponge cylinder that prevents to absorb water next time absorbs support plate water. The substrate 9 can be used for filtering the cleaned water through the filtering holes for primary filtering, so that the water can be recycled. The squeezing roller adjusting mechanism can adjust squeezing force between the squeezing roller and the water absorption sponge roller to ensure that water of the water absorption sponge roller is smoothly squeezed out without influencing the water absorption of the water absorption sponge roller on the support plate. The buffer spring 1803 has a buffer function in the process of mutual extrusion of the extrusion roller and the water absorption sponge roller. Under normal conditions, the squeezing roller 1902 and the absorbent sponge roller 17 are in contact, the squeezing roller 1902 is located obliquely below the absorbent sponge roller 17, and the adjusting screw 1802 is screwed to press the lower beam 1901 of the rotating frame 19 (as shown in fig. 6, the rotating frame 19 has a clockwise driving force after the lower beam 1901 is pressed down), so that the squeezing roller 1902 and the absorbent sponge roller 17 are in closer contact (squeezing the absorbent sponge roller), otherwise, the squeezing force of the squeezing roller 1902 to the absorbent sponge roller 17 is weakened.

During the in-service use, the width that absorbs water among this belt cleaning device mechanism is greater than the wiper mechanism, because in automatic in-service use, laser printing can diversified design, can be the carousel formula, can be a style of calligraphy pattern.

When the cleaning device is applied specifically, the cleaning device comprises the following steps:

the method comprises the following steps: the conveying mechanism can accurately convey the printed duplex carrier plate to a station (corresponding to the left part of the waterproof outer cover) of the cleaning device.

Step two: raise whole belt cleaning device through electronic elevating system, the waterproof tuft that works as waterproof dustcoat left part just in time is located two support plates top all around, and waterproof dustcoat and waterproof tuft can wrap up two printing support plates promptly, prevent to splash out at the cleaning process normal water, influence other stations.

Step three: and the cleaning mechanism is moved by the transverse moving mechanism to clean the carrier plate, the carrier plate is cleaned by the first cleaning water jet cutter in the cleaning process, residues on the carrier plate are brushed off by the cleaning roller hairbrush, and finally the carrier plate is cleaned by the second cleaning water jet cutter to finish cleaning the carrier plate.

Step four: after the cleaning mechanism cleans the printing support plate, the conveying mechanism moves the support plate to the next station, and when the support plate passes through the water absorption sponge roller, the water absorption sponge roller can absorb water drops on the support plate.

To in laser printing, the cleanliness of support plate has the key effect to the grid line on the battery piece that laser printed, and above-mentioned support plate belt cleaning device adopts the integrated design, can be fine carry out the automatic operation to the support plate and wash.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and are not limited, and although the detailed description is made with reference to the embodiments of the present invention, it should be understood by those skilled in the art that the technical solutions of the present invention are modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should be included in the protection scope of the claims of the present invention.
