Description

A device and point gum machine of gluing for point gum machine nozzle Technical Field The utility model belongs to the technical field of semiconductor integrated circuit manufacturing, and relates to a glue scraping device for a nozzle of a glue dispenser and the glue dispenser. Background In the field of semiconductor manufacturing, dispensing machines are widely used in processes such as chip packaging, wafer level packaging, microelectronic assembly, thermal management, and the like. In the working process of the dispenser, as the dispensing needle is directly contacted with glue and a workpiece, glue residues and pollutants are easy to accumulate, so that the problems of irregular glue points, wiredrawing, blockage and the like are caused. Therefore, wiping of the dispensing needle is a key step of ensuring dispensing accuracy, stability and production efficiency. However, the wiping cloth on the existing wiping platform is retracted after wiping is completed, and it is difficult to review the previous wiping trace. When an operator performs inspection, abnormal wiping marks can be moved to the lower part of the platform, and the operator cannot intuitively observe the change of the wiping condition of the dispensing needle, so that the abnormality of the dispensing needle is difficult to discover in time. Therefore, how to provide a glue-spreading device for a nozzle of a glue-spreading machine and a glue-spreading machine to completely display glue-spreading marks, so that operators can find out anomalies of a glue-spreading needle in time, which is an important problem to be solved by those skilled in the art. It should be noted that the foregoing description of the background art is only for the purpose of providing a clear and complete description of the technical solution of the present application and is presented for the convenience of understanding by those skilled in the art. The above-described solutions are not considered to be known to the person skilled in the art simply because they are set forth in the background of the application section. Disclosure of utility model In view of the above-mentioned drawbacks of the prior art, the present utility model is directed to a dispensing device for a dispensing machine nozzle and a dispensing machine, which are used for solving the problem that in the prior art, a wiping platform cannot completely show wiping marks, so that an operator cannot find out an abnormality of a dispensing needle in time. To achieve the above and other related objects, the present utility model provides a glue spreading device for a dispenser nozzle, comprising: a drive motor; the rotating rod is positioned above the driving motor and connected with the output end of the driving motor to rotate under the driving of the driving motor, the central shaft of the rotating rod is arranged along the vertical direction, The rotating disc is positioned above the rotating rod and connected with the rotating rod; A wiping cloth covering the upper surface of the turntable; And the rubber valve lens is positioned above the rubber cloth. Optionally, a coupling is provided between the drive motor and the rotating rod.
