Description

Technical Field

[0001] The present invention relates to the field of conveying technology, and in particular to an automatic conveying device and method for producing LED display screen brackets. Background Art

[0002] In the production process of LED display brackets, when it comes to the production of back panels, hot pressing is generally used as an important process. In this process, in order to ensure that the subsequent demolding operation can proceed smoothly, an appropriate amount of oil is usually applied to the inside of the corresponding mold. The use of this oil is crucial for the demolding step. However, some of the oil on the surface of the mold may remain and adhere to the conveyor belt during transportation. After long-term use, dust, oil, debris and other pollutants will accumulate on the surface of the conveyor belt. These pollutants will not only affect the normal operation of the conveyor belt, but also pollute the back panel of the conveyed bracket, resulting in a decrease in product quality. Traditional cleaning The cleaning method may only rely on simple wiping or irregular manual cleaning, which is difficult to completely remove stubborn stains on the surface of the conveyor belt, and the cleaning process may cause damage to the conveyor belt. In addition, there is a lack of effective drying methods, so that the conveyor belt cannot be restored to use in time after cleaning, which is prone to secondary pollution or affects the quality of subsequent products, which further reduces production efficiency and increases labor costs. At the same time, the tension adjustment of the conveyor belt is not flexible and accurate enough, and the conveyor belt may slip or be too tight, affecting power transmission and the service life of the equipment.

[0019] Compared with the prior art, the advantages and positive effects of the present invention are: 1.

When the tension of the conveyor belt needs to be adjusted, one of the support rollers is driven to rotate by a motor, and the support roller drives the other half gear to rotate through one of the half gears. At this time, the two support rollers drive the rotating plate to rotate, and the rotating plate drives the adjusting roller to rotate. The adjusting roller pushes the conveyor belt. At this time, the tension of the conveyor belt can be adjusted. By adjusting the tension, it can be ensured that there is sufficient friction between the conveyor belt and the support roller and the adjusting roller to prevent the conveyor belt from slipping during operation and to avoid the conveyor belt being too loose. The conveyor belt may not be able to effectively transmit power, resulting in the inability to normally transport materials and affecting production efficiency. By adjusting the angles of the two adjusting rollers, the tension of the conveyor belt can be adjusted, and the conveyor belt and the roller can be closely fitted to ensure the effectiveness of power transmission.

[0020] 2. The present invention proposes an automated conveying device and method for producing LED display screen brackets, which can drive the left adjusting roller to rotate through the transmission of the conveyor belt, and the adjusting roller drives the second rotating plate to rotate through the first rotating plate, and the second rotating plate drives the clamping block to move through the push rod, and the clamping block slides on the inner wall of the internal thread groove of the tooth column, and then the tooth column can be driven to rotate back and forth, and the tooth column drives the spur gear to rotate through the clamping column, and the spur gear drives the cleaning brush to rotate through the connecting rod, and then the surface of the conveyor belt can be cleaned, and the bidirectional rotating cleaning brush can cover a larger cleaning range and can apply force to these pollutants from multiple angles, so that the cleaning is more comprehensive, and the pollutants can be peeled off from the surface of the conveyor belt more quickly, thereby improving the cleaning efficiency, thereby shortening the time required for the entire cleaning process and improving the overall working efficiency of the automated conveying device.

[0021] 3. The present invention proposes an automated conveying device and method for producing LED display screen brackets, which can drive the rack to move up and down through the rotation of the tooth column, and the rack drives the piston to move up and down through the lifting plate. When the piston moves down, the cleaning liquid inside the positioning hole is pushed out and sprayed intermittently on the conveyor belt through the nozzle. The intermittent spraying method can ensure that there is enough detergent to play a role and avoid the waste caused by excessive use of detergent. At the same time, spraying detergent can make it easier for oil stains to separate from the surface of the conveyor belt. The chemical action of the detergent combined with the physical action of the cleaning brush can significantly improve the cleaning effect, more thoroughly remove various pollutants on the surface of the conveyor belt, and ensure that the conveyor belt remains in a good cleaning state.

[0022] 4. The present invention proposes an automated conveying device and method for producing LED display screen brackets, wherein the tooth column can drive the positioning cylinder to rotate when rotating, and the positioning cylinder drives the positioning rod to rotate through the synchronous belt, and the positioning rod drives the fourth rotating plate to rotate through the third rotating plate, and the fourth rotating plate drives the shaking plate to shake, and the cleaning liquid passes through the shaking plate through the through hole on the shaking plate and contacts the sponge. The cleaning liquid can be foamed by continuous shaking and friction between the sponge, the belt and the cleaning liquid. The foaming process can make the cleaning liquid better dispersed and expanded on the surface of the conveyor belt, increase the contact area between the cleaning liquid and the pollutants, and can act on the pollutants faster, accelerating the dissolution and removal process. At the same time, when the sponge contacts the conveyor belt, it will generate continuous friction on the surface of the conveyor belt. This friction can effectively remove stubborn dirt, oil, dust and other impurities attached to the surface of the conveyor belt, reducing the time and workload required for cleaning.

[0023] 5. The present invention proposes an automated conveying device and method for producing LED display screen brackets, which drives the fan to rotate through a connecting rod. The airflow of the fan blades can clean the floating dust through the air vents on the left side, so that the floating dust is blown away from the conveyor belt. Some oil stains on the surface of the conveyor belt are cleaned by a detergent, and the airflow enters through the middle air vent to blow out the liquid. After the airflow enters the air vent on the left side, the surface of the cleaned conveyor belt can be heated and dried by heating with a heater. The moisture can be quickly removed by blowing and drying, shortening the drying time of the conveyor belt, so that the conveyor belt can be restored to normal working state faster, avoiding water stains on the surface of the conveyor belt, which may absorb dust and impurities in the air and re-contaminate the conveyor belt, affecting its cleanliness, thereby improving the operation efficiency of the entire device.
