A cleaning aid

Abstract

The invention discloses a cleaning auxiliary jig, comprising: a cleaning frame used to be put into a cleaning tank of a cleaning machine; The height of the high bar is higher than that of the carrying bar, so that the height of a corner of the workpiece on the cleaning frame is lower than the height of any position on the workpiece except the corner. In the process of slow pulling after cleaning, when the cleaning frame is pulled vertically upward according to the existing method, the workpiece is always translated upward with one corner facing downward, and the water on the surface of the workpiece flows out uniformly through the downward corner of the workpiece. It reduces the residual water marks on the bottom side of the workpiece and ensures the quality of the subsequent silk screen printing of the workpiece. The cleaning auxiliary jig does not need to change the cleaning process of the workpiece, it only needs to be put into the cleaning machine, without control, it can be cleaned according to the normal production process, the process is simple, the cost is low, and the yield rate is high.

Description

technical field [0001] The invention relates to the technical field of electronic product process equipment, and more specifically relates to a cleaning auxiliary jig. Background technique [0002] In consumer electronic products, materials such as glass, ceramics, and sapphire are gradually being used, for example, in mobile phone back covers, mobile phone fingerprint recognition covers, and camera covers. [0003] Workpieces made of glass, ceramics, and sapphire usually need to be cleaned in a washing machine before silk screen printing to ensure the quality of silk screen printing. [0004] However, during the slow cleaning process of workpieces made of glass, ceramics, and sapphire, water stains are likely to remain on the surface, and obvious watermarks or steam watermarks are formed on the surface of the workpiece after drying, which will cause watermark color or oil loss after silk screen printing Bad etc. [0005] In order to improve the surface quality of workpiec...

Problems solved by technology

However, in the cleaning process, a certain amount of antistatic liquid needs to be added regularly, for example, adding 100ml every two hours, and the production cost is high; in addition, the antistatic liquid has a risk of scattering oil to the ink during the silk screen printing process; and the cleaning machine After adding the antistatic fluid for a long time, on the one hand, the pollution is serious, on the other hand, the concentration of the antistatic fluid is too high, which will lead to poor white spots on the surface of the workpiece and affect the quality of silk screen printing
