lijiang Auotomatic Glass Cutting Line

The overall plan of the project: CNC automatic glass cutting line is composed of an automatic loading table, automatic cutting table, and air-floated breaking table. The automatic glass cutting line is mainly used in the processing of flat glass, which can quickly and accurately load sheets, cut straight-line,special-shaped glass, and air-floated mechanical breaking sheets.

The Working flow is as follows: Loading table uses mechanical turnover, through the vacuum suction cup taking glass sheet from the rack, put down to the loading table. The glass is conveyed to the cutting table through the roller on the loading table and the conveyor belt on the cutting table. The cutter holder on the cutting beam of the cutting machine drives the cutter to move at high speed in the X direction and Y direction by servo motor. Using Z-axis motor rotation to control the tangent trajectory of the tool. At the same time, the cutter pressure and the depth of the cutter are controlled by analog quantity, and the four axes are operated simultaneously to cut. When the cutting is finished, the glass sheet is sent to the air-floated breaking table for breaking through the air cushion formed by the conveyor belt and the breaking table.

lijiang Fully Auotmatic Glass loading Table

①Basic working principle:

It is mainly used for automatic glass loading. After putting the glass in the designated position and giving the signal of loading, the big arm turns up about 95 degrees through the overturning mechanism, and the whole machine starts to move forward. When the induction device on the small arm touches the glass, the whole machine stops walking and the glass is sucked by the suction cup through the vacuum system on the glass,small arm lifting motor lifts the glass upward and backward about 80 mm. The walking motor retreats and the big arm falls down. When the bing arm is in place, the suction cup under the glass begins to blow. When the small arm falls down, the glass falls on the conveyor wheel. Finally, the glass is conveyed to the cutting table by the conveyor wheel.

②Equipment Composition:

It is mainly composed of frame mechanism, turnover mechanism, sucker lifting mechanism, X-axis walking mechanism, Y-axis walking mechanism, conveying mechanism, vacuum and gas circuit control system and electrical control system.

③Detailed working steps::

The whole working process can be accomplished by PLC automatic control or manual control. The manual mode is mainly suitable for equipment adjustment and maintenance. Each action can be completed independently or can be used for normal work.After giving the loading signal (manual and automatic), the arm turns upward about 95 degrees through the overturning mechanism, and the whole machine starts to move forward. When the induction device on the arm touches the glass, the whole machine stops walking.The vacuum system works, the glass is sucked by the sucker through vacuum systems. When the vacuum pressure reaches the set pressure, the vacuum pump stops. The sucker's telescopic connecting rod mechanism lifts the glass back and up 80 mm through the arm-lifting motor. Stopping for about 1.5 seconds to make sure the glass is sucked up, the big arm  driven by a motor to reverse the glass to the transmission roller. The suction cup under the glass begins to blow, and the telescopic connecting rod mechanism makes the suction cup and the glass fall at the same time.When the glass falls on the conveyor roller, the small arm continues to fall, the glass is separated from the suction cup, and the conveyor starts to send the glass sheet to the front end of the loading machine and stop at the signal point.Then the whole frame moves automatically to find the zero position and stops. Waiting for the signal from the cutting table, the glass can be sent to the cutting table at the same speed as the conveyor belt on the cutting machine. After the glass is sent out,automatically repeat the work cycle. The machine can select any position according to the required glass thickness.
