Positioning method used in sandwich glass production process

Abstract

The invention provides a positioning method used in a sandwich glass production process. The method comprises the following steps of: 1) conveying glass sheets onto a positioning device platform under the traction of a servo driving device; 2) driving the glass sheets to move in the Y axis direction by using the servo driving device, transmitting a signal to the servo driving device by using a sensor, controlling a glass transmission wheel to slow down and stop driving, raising a Y axis baffle plate after a Y axis cylinder receives the signal of the sensor, forcing the glass sheets to stop moving forward through mechanical force, and quickly lowering the Y axis baffle plate to the original place; 3) conveying the glass sheets in the X axis direction in a similar way as the conveying in the Y axis direction except that an X axis baffle plate does not move downwards to the original place; and 4) slowly erecting the Y axis baffle plate, and moving and adjusting the glass sheets in a direction opposite to the direction in the step 2) at the low speed so as to complete secondary positioning in the Y axis direction. The positioning method is applied to a sheet combining process for a sandwich glass production line, so that automatic, quick and accurate positioning of glass sheets is realized, waste of raw materials is avoided, and production cost is lowered.

Description

technical field [0001] The invention belongs to the field of laminated glass manufacturing, in particular to a positioning method for laminated glass in the production process. Background technique [0002] In the production process of laminated glass, the lamination process is to line a layer of polyvinyl butyral film (ie PVB film) between two pieces of glass, and remove the air between the glass and PVB film. In the actual production process, the precise positioning technology of glass sheets in the laminating process can improve the utilization rate of raw materials, avoid material scrapping caused by inaccurate alignment of glass sheets, and is also the key to ensuring the quality of laminated glass. In the traditional laminated glass production, manual positioning is generally adopted, that is, the glass is directly laminated on the glass that has been pasted with PVB film. This may cause waste of raw materials due to inaccurate alignment of the glass sheets, and it can...

Problems solved by technology

In the traditional laminated glass production, manual positioning is generally used, that is, the glass is directly laminated on the glass that has been pasted with PVB film. This may cause waste of raw materials due to inaccurate alignment of the glass sheets, and it cannot meet the requirements of comparison. The production process requirements of precision laminated glass

In addition, the manual positioning method cannot meet the requirements of assembly line production, so the fast, automatic and accurate positioning method has broad application prospects and has good promotion and utilization value
