龙门框架采用去应力焊接钢结构，用于横向行走。上料系统包括：行走单元，升降单元和真空抓取系统。行走单元通过直线导轨导向，伺服电机通过齿轮和齿条传动。升降系统通过直线导轨导向，伺服电机通过齿轮和齿条传动。吸盘系统包括可调横杆，横杆的位置固定，横杆上安装了若干个真空吸盘，每一组吸盘由单独的气路控制，确保设备工作的连续性，每个吸盘由弹簧连接杆联结，保正了吸盘与工件接触有足够的缓冲空间，每个吸盘的纵向位置可调，操作者只需松开固定扳头就可以按照板材的尺寸调整吸盘的位置。
It consists of a gantry frame made of welded , carbon steel and suitably dimensioned to support the working stress . The device consists of the following groups : Translation unit , Liffing unit , Vacuum pick up unit . The trans 一 lation unit 15 guided by the liner guide , driven by the servo motor via gear and pinion . The litting unit guided by the liner guide , driven by the pneumatiC piston . The piCk 一 up unit 15 Composed of 3 adiustable holder bars with certaino suction cups , the bar 15 in a fixed position but each suction cup can move longitudinally , the operator can release the fixture , adiust the position of the suction cup , lock again the fixture easily . Each suction cup 15 connected to the individual pneumatic piping to ensure the smooth operation of the system , each suction cup 15 connected to the spring arbor to ensure the enough buffering space between cups and workpiece .
