Abstract

The invention discloses a full-automatic grinding and cleaning machine and a grinding and cleaning technology thereof. The full-automatic grinding and cleaning machine comprises a feeding part, a CF cleaning part, a TFT cleaning part, a two-fluid cleaning and drying part, and a discharging part, wherein the feeding part, the CF cleaning part, the TFT cleaning part, the two-fluid cleaning and drying part and the discharging part are sequentially arranged on a machine table in the flow direction of glass pieces; the to-be-cleaned glass pieces are sequentially transported from the feeding part tothe CF cleaning part, a CF surface is cleaned through the CF cleaning part, the TFR surface is cleaned through the TFT cleaning part, and the CF surface and the TFT surface are cleaned by the two-fluid cleaning and drying part simultaneously and then dried, and the dried glass pieces are discharged and exported through the discharging part. According to the full-automatic grinding and cleaning machine and the grinding and cleaning technology thereof, transmission of the small and micro-sized glass pieces is effectively realized, and the problems of positional displacement and motion interference of the glass pieces in the two-fluid cleaning and drying process are effectively avoided; and rotating, material splitting, and exporting of the glass pieces are realized through cooperation of adouble-glass transmission channel formed by a gap between adjacent conveying rollers in an upward extending mode and a discharging mechanical arm, the height of a brush can be controlled in real time,displacement of the glass pieces is avoided, and the cleaning efficiency of the brush and the real-time cleaning versatility of the brush are effectively improved.

Description

technical field [0001] The invention relates to the field of automatic manufacturing, in particular to a fully automatic grinding and cleaning machine and a grinding and cleaning process thereof. Background technique [0002] In the manufacturing process of liquid crystal modules, polarizer bonding process is involved, and before the polarizer is bonded, it is necessary to clean the glass sheet of the polarizer bonding carrier. The glass sheet cleaning process includes brush cleaning, grinding disc grinding and bonding. For objects attached to the glass sheet, two-fluid rinsing, etc., the general process steps are brush cleaning, grinding disc cleaning, brush cleaning, two-fluid rinsing, and drying. The size of traditional LCD screen or OLCD screen is more than 3 inches. [0003] After the glass sheet has been ground and brushed, it needs to be flushed with a mixture of gas and water vapor in order to wash away the remaining objects after grinding and brush cleaning. The r...

Problems solved by technology

The smart watches and bracelets that have appeared in recent years have made the screen smaller and more portable, requiring the size of the screen to be reduced to less than 1 inch, such as 0.68 inch; the existing two-fluid cleaning and drying process cannot adapt to this small and micro screen. The manufacture of large-scale screens has the following technical defects: 1. The gap between two adjacent transmission rollers in the existing transmission production line is too large. Small-sized glass sheets such as 0.68-inch glass sheets have a length and width of 11mm*22mm. When the transmission roller is transmitting, it is very easy to slip from the gap between two adjacent transmission rollers, resulting in transmission failure; 2. Multiple transmission rollers need to rotate synchronously to transport the glass sheet forward. After reducing the distance between adjacent transmission rollers, The problem of synchronous rotation drive of multiple transmission rollers; 3. When the glass sheet is washed and dried by two fluids, the impact force generated from the upper and lower sides will cause the position of the glass sheet to shift on the transmission roller. Therefore, it is necessary to ensure that the glass sheet At the same time of forward transmission, limit the glass sheet on the transmission roller; 4. Interference with the linear motion of the glass sheet when limiting the glass sheet

[0004] In addition, after the two-fluid washing and drying process of the glass sheet is the unloading process, the function of the unloading process is to connect the drying process and the subsequent polarizer bonding process, and to export the dried glass sheet; The material station cannot adapt to the transmission of this kind of small and micro-sized screen, and there are the following technical defects: 5. In order to improve the efficiency of grinding and cleaning small-sized screens, using the characteristics of small-sized screens, simultaneous grinding and cleaning can be used during grinding and cleaning 2 One or more glass sheets; two or more glass sheets are arranged side by side on the drive roller, and are synchronously conveyed by the drive roller; however, the subsequent polarizer bonding process requires only single sheet feeding; Therefore, between the drying process and the polarizer bonding process, it is required to divide and transfer two or more glass sheets.

The brush mechanism of the traditional abrasive cleaning machine generally adopts a fixed installation structure, that is, the installation height of the brush is adjusted in advance according to the installation relative position between the mobile platform carrying the adsorbed glass sheet and the brush mechanism and the thickness of the glass sheet; In the actual production process, the installation position of the brush changes. When the direction of the brush approaches the glass sheet, the brush will interfere with the movement of the glass sheet on the moving platform, causing the glass sheet to overcome the adsorption force of the moving platform and shift its position. When the direction away from the glass sheet changes, the cleaning effect will be reduced; and in the actual production process, the process requirements and thickness of different screens are different, and the height of the brush needs to be adjusted in real time. The installation height adjustment of the brush mechanism with a fixed installation structure is complicated and inconvenient , will increase the labor cost; therefore, it is necessary to design a flexible brush mechanism, which can control the height of the brush in real time according to the actual processing conditions such as glass sheet cleaning requirements and thickness
