Description

Technical Field

[0001] The utility model relates to the field of glass manufacturing, in particular to an automatic positioning mechanism based on servo control and used on a glass transmission line. Background Art

[0002] As one of the raw materials for producing photovoltaic modules, the output of photovoltaic glass has increased year by year with the development of the new energy industry.

[0003] The production process of photovoltaic glass is complicated. The glass needs to be transferred between multiple workstations through a transmission line. On the glass transmission line, some sections of the transmission roller table need to side-push the glass for positioning. Currently, most of the glass side-push positioning mechanisms use a combination of a hand-cranked screw mechanism and a cylinder for positioning. The adjustment process is to first adjust the static edge handle to determine the static edge position, place a piece of glass for production on the transmission roller table, start the side push cylinder to complete the advancement, and then adjust the dynamic edge handle to move the dynamic edge block to the position to press the glass. During normal production, after the positioning sensing photoelectric switch senses the entry of glass, the PLC is started to control the movement of the side push cylinder, and the side push cylinder advances to push the glass to a limited position, and the side push cylinder exits with a delayed delay.

[0004] When the glass specifications are changed, manual recalibration is required. The static edge position remains unchanged, and the dynamic edge position needs to be readjusted to meet the positioning requirements of the new glass specifications. The disadvantage of the existing glass side-pushing positioning mechanism is that there are multiple sets of similar positioning mechanisms on the production line. When the glass specifications are changed, multiple sets of mechanisms need to be adjusted, and manual adjustment is too inefficient.

[0005] In order to solve the above technical problems, the utility model proposes an automatic positioning mechanism based on servo control. Utility Model Content

[0013] Preferably, the stationary edge stopper and the dynamic edge stopper protrude from the top planes of the plurality of transmission rollers.

[0014] Preferably, the side thrust cylinder is located below the top plane of the plurality of conveying rollers.

[0015] In actual use, when the glass specifications are changed, the position of the moving edge block needs to be adjusted. The specific adjustment process is as follows: the position of the static edge block remains unchanged. First, after the side push cylinder is started and pushed, the distance D from the static edge block to the dynamic edge block is measured. The glass width W is input into the upper computer of the connection system, and the dynamic edge servo motor of the automatic servo positioning mechanism is automatically adjusted according to the distance L=WD. When L is positive, the dynamic edge servo motor drives the cylinder mounting platform to move toward the edge of the roller table. When L is negative, the servo motor drives the cylinder mounting platform to move toward the middle of the roller table. When the glass width W changes, the dynamic edge servo motor can automatically adjust according to the changed position, which improves the automation level of the production line and reduces the labor intensity.
