Description

Technical Field

[0001] The invention relates to the technical field of automated cleaning, in particular to a pre-cleaning robot for automated production of color-coated plates. Background Art

[0002] Color coated steel sheet is also called color steel sheet. It is a composite sheet made of cold rolled steel sheet or ordinary galvanized steel sheet, which is coated with paint after surface pretreatment. Color coated steel sheet is light and beautiful, and has good anti-corrosion performance. It is widely used in the fields of construction, vehicle manufacturing, home appliance industry, electrical industry, etc.

[0003] Before the production and processing of color-coated plates, workers need to pre-clean the surface of the steel plates to be processed. The pre-cleaning process refers to the process of degreasing, dust cleaning, chemical residue cleaning, etc. on the surface of the steel plates. The above cleaning processes will be completed separately using corresponding equipment. For example, a patent for a substrate cleaning device for color-coated plate processing disclosed by a person skilled in the art has a publication number of CN212525121U. The patent mainly improves the pre-cleaning process of the substrate (that is, the steel plate to be processed) in the production process of the color-coated plate, and allows the steel plate to be processed to pass between the first guide roller and the second guide roller, and after passing through the two cleaning rollers, it is conveyed between the first conveying roller and the second conveying roller. People drive the first threaded rod to rotate by rotating the knob, and then drive the first mounting block to move downward, so that the first guide roller moves downward and approaches the second guide roller, so that the steel plate to be processed can be clamped, and the second mounting block is driven downward by rotating the second threaded rod, and then the first conveying roller is driven to move toward one end of the second conveying roller, so that the first conveying roller clamps the steel plate to be processed on the second conveying roller, and then the controller controls the first conveying motor and the second conveying motor to rotate simultaneously, and the second conveying motor rotates in the opposite direction to the first conveying motor, and the second conveying motor rotates in the opposite direction to the first conveying motor, so that the steel plate to be processed can be driven. The processed steel plate is conveyed to one end, at this time, water is added into the flushing pipe through a water pump, so that water is sprayed out through a nozzle to flush and moisten the surface of the processed steel plate, and then the cleaning motor rotates to drive the cleaning roller to rotate, and the two cleaning rollers are connected by gears, so that the two cleaning rollers also rotate in opposite directions to each other, and the cleaning motor rotates in the opposite direction to the first conveying motor, so that the cleaning roller rotates to brush off impurities on the surface of the processed steel plate, and then the processed steel plate can be cleaned with good cleaning effect. When the processed steel plate is conveyed, it is clamped by the first guide roller and the second guide roller, so that during the conveying process, the processed steel plate will have a certain force to drive the L-shaped plate to move, so that the L-shaped plate squeezes the holding spring, so that the holding spring always gives the L-shaped plate a reverse force, so that the processed steel plate always maintains a relatively good tension, which plays a buffering role. This device has a good cleaning effect on the processed steel plate, and can convey steel plates of different thicknesses to be processed, and automatically adjust the tension, with good buffering effect, which is convenient for people to use. Although the above patent can achieve a good pre-cleaning effect on the steel plates to be processed, the device disclosed in the patent requires the steel plates to be processed to remain in a horizontal state during the cleaning process. The horizontal steel plates to be processed are prone to retain liquid on the upper surface, and the drying effect is poor. Moreover, the pre-cleaning process can only be performed on one steel plate to be processed at a time, and the effect of batch cleaning of the steel plates to be processed cannot be achieved. It is also impossible to solve the technical problem of how to avoid interference and ensure the cleaning quality during the synchronous cleaning of batches of steel plates to be processed.

[0004] In addition, those skilled in the art have also disclosed a substrate degreasing device for color-coated plate processing, and its publication number is: CN211972460U; this patent mainly improves the degreasing and cleaning process of the substrate of the color-coated plate (that is, the steel plate to be processed), and this patent conveys the steel plate to be processed by a conveying roller. During the conveying process, the electric heating plate is controlled by the control panel to heat up, and the surface of the steel plate to be processed of the color-coated plate is heated, so that the grease on the surface of the steel plate to be processed of the color-coated plate is activated, and then the cleaning liquid is pumped into the flushing pipe by a high-pressure pump, and sprayed out by a high-pressure nozzle, and the surface of the steel plate to be processed of the color-coated plate is high-pressure flushed. Since the grease on the surface of the steel plate to be processed of the color-coated plate has been heated and activated, it can be easily flushed off, and then the two The baffle device is located on both sides of the color-coated steel plate to be processed, and the scraper is in contact with the surface of the color-coated steel plate to be processed. The residual cleaning liquid on the color-coated steel plate to be processed is scraped off by the scraper during the transportation process and falls inside the U-shaped shell. The scraper will always be close to the surface of the color-coated steel plate to be processed under the elastic force of the spring, so that after the color-coated steel plate to be processed passes through the baffle device, only a small amount of cleaning liquid will remain on the surface. Then, the blower in the drying device blows air, and the electric heating wire heats up to blow out hot air to dry the surface of the color-coated steel plate to be processed, so as to facilitate subsequent processing. This device can degrease the color-coated steel plate to be processed, and it is convenient to dry the color-coated steel plate to be processed after degreasing, and the drying efficiency is high, which is convenient for people to use. Similarly, the above patent can only perform one-way cleaning and drying for a piece of color-coated plate, and cannot meet the requirements of batch cleaning and repeated cleaning of the steel plate to be processed. Such a one-way flushing method not only increases the production cost, but also increases the cumbersomeness of the production process, thereby affecting the efficiency of processing and production.

[0005] In summary, those skilled in the art need a pre-cleaning system that can clean color printing plate substrates (that is, steel plates to be processed) in batches and ensure cleaning efficiency and cleaning quality. Summary of the invention

At this time, one or more nozzles in the cleaning chamber begin to spray high-pressure fluid. It should be noted that the high-pressure fluids sprayed by different nozzles are not the same, and the sprayed high-pressure fluids need to meet the requirements of the corresponding cleaning process. For example: when removing dust, you can choose to open the nozzle that sprays high-pressure clean water, and when removing oil and grease, you can choose to open the nozzle that sprays high-pressure cleaning fluid and the nozzle that sprays high-pressure hot air flow; the transmission rollers 5 in the brackets 1 3 and brackets 2 4 rotate synchronously forward, and at this time the steel plates to be processed in the bracket 1 3 pass through the corresponding cleaning chamber, and the nozzles in the cleaning chamber flush the two sides of the steel plates to be processed. When the steel plates to be processed completely pass through the cleaning chamber and reach the bracket 2 4, the steel plates to be processed complete the first cleaning process.

[0047] After the first cleaning is completed, the host controls the electric screw 15 to move, and the nut on the electric screw 15 is lifted and lowered with the mounting seat 16. During the lifting process, the camera collects the situation of the side surface of the steel plate to be processed and presents it to the staff through the display. The staff judges the state of the steel plate to be processed after the first cleaning through the image displayed on the display. If the steel plate to be processed reaches the pre-cleaning effect after the first cleaning, the electric conveying unit where the steel plate to be processed is located continues to rotate forward and sends the steel plate to be processed out of the bracket 2 4, and the staff transfers the steel plate to be processed to the subsequent coating equipment; if the steel plate to be processed does not reach the pre-cleaning effect after the first cleaning, the electric conveying unit where the steel plate to be processed is located starts to reverse and sends the steel plate to be processed back to the bracket 1 3. When the steel plate to be processed is When passing through the cleaning chamber, the nozzle in the cleaning chamber uses high-pressure fluid to clean the steel plate to be processed for the second time, and after the steel plate to be processed reaches bracket one 3, the electric conveying unit starts to rotate forward and sends the steel plate to be processed into bracket two 4 again. When passing through the cleaning chamber, the nozzle uses high-pressure fluid to clean the steel plate to be processed for the third time. When the steel plate to be processed reaches bracket two 4 again, the electric screw 15 drives the camera to start lifting and collecting the image of the surface of the steel plate to be processed again. The staff determines whether the steel plate to be processed has achieved the pre-cleaning effect based on the image collected again. If the pre-cleaning effect is achieved, the host controls the electric conveying unit to send the steel plate to be processed out and transfer it to the subsequent coating equipment. If the pre-cleaning effect is still not achieved, the above process is repeated until the steel plate to be processed achieves the pre-cleaning effect.

[0048] Embodiment 2;

[0049] like Figure 5 As shown, two motorized rollers are added in the cleaning chamber, and the positions of the two motorized rollers correspond to the positions of the two sets of clamps respectively. Multiple brushes are arranged on the surface of the motorized rollers. When the steel plate to be processed passes through the cleaning chamber, the steel plate to be processed will pass through the gap between the two motorized rollers. The two motorized rollers rotate and use multiple brushes to scrub the surface of the steel plate to be processed. The rest is the same as in Example 1.
