Yet, when glass substrate when stop position produces bigger inclination, the glass substrate of being clamped by the side block of both sides will break away from and the contacting of front block, promptly the physical location of glass substrate has produced back deviation with respect to theoretical position.When deviation is big, by robot send into the glass substrate of magnesium vapour-deposition equipment can not be in magnesium vapour-deposition equipment fragile screen behind smooth delivery of power or the vapor deposition.
The utility model content
In view of this; The utility model provides a kind of glass substrate positioning device; Can accurately locate glass substrate, eliminate the back deviation, the glass substrate that guarantees to send into evaporated device by robot not because of deviations cause can not smooth delivery of power or vapor deposition after fragile screen.
For realizing above-mentioned purpose, the utility model provides following technical scheme:
A kind of glass substrate positioning device; Comprise loading stage, front block, side block, front sensor and controller; The front block is positioned at a loading stage top glass substrate direction of motion end pointed, and the side block is positioned at the loading stage both sides, and front sensor is positioned at the rectangular area that surrounded by front block and side block and near the front block; Block all can horizontal movement on loading stage; Controller comprises also that according to first detection signal control front block and the action of side block of front sensor glass substrate positioning device comprises can be perpendicular to the back block of loading stage plane motion.
Preferably, back block boundary line setting behind the glass substrate theoretical position.
Preferably, back sensor is sent second detection signal to controller to the back during block jack-up glass substrate.Preferably, back transducer is positioned at the rectangular area that is surrounded by front block, side block, back block, and near said back block.
Preferably, back transducer is a Fibre Optical Sensor.
Preferably, glass substrate positioning device also comprises and receives the warning device that externally gives the alarm behind the alarm command that controller sends.
Preferably, glass substrate positioning device also comprises the warning device that externally gives the alarm behind reception second detection signal
Preferably, warning device is a buzzer.
Glass substrate positioning device disclosed in the utility model has increased the back block.Glass substrate is placed into loading stage, but produces bigger inclination at stop position, and this moment, front sensor detected glass substrate arrival stop position; Front sensor sends first detection signal to controller; Controller orders the back block to rise successively, and to pusher, the side block of both sides is to the motion of loading stage central authorities with glass substrate for the front block; Four direction positions glass substrate device in front, rear, left and right at this moment; Its physical location is exactly the theoretical position for its setting, has eliminated back deviation, the glass substrate that guarantees to send into evaporated device by robot not can because of deviations cause can not smooth delivery of power or vapor deposition after fragile screen.
Secondly, glass substrate positioning device disclosed in the utility model has also increased back transducer.If the back sensor sensing exceeds the back theoretical position for its setting to glass substrate; Can be by the vertical back block jack-up of rising; Can send signal to controller, controller is received signal, the action of arresting stop; Display alarm information on touch screen simultaneously, and have fault to need to handle through the buzzer warning alert.

Embodiment
The utility model provides a kind of glass substrate positioning device; Be mainly used in the colorful display screen manufacturing equipment; This device can accurately be located the glass substrate on the loading stage; The back deviation that elimination possibly occur, the glass substrate that guarantees to send into evaporated device by robot not can because of deviations cause can not smooth delivery of power or vapor deposition after fragile screen.
In order to make those skilled in the art person understand the utility model scheme better, the utility model is done further to specify below in conjunction with accompanying drawing and embodiment.
Embodiment 1 as shown in Figure 2 is a kind of glass substrate positioning device; Direction of motion when regulation is put into loading stage with glass substrate is loading stage direction forward; According to the actual production requirement, on loading stage, set a rectangular area, simultaneously as the theoretical position of glass substrate.This device comprises loading stage, one group of front block, two groups of side blocks, one group of back block, front sensor and controller.The front block is positioned at loading stage to last end, and two groups of side blocks are symmetrically distributed in the both sides of loading stage, and the back block is positioned at the loading stage rear portion, and front sensor is installed on the preceding boundary line of glass substrate theoretical position; Front block and side block can horizontal movements on loading stage, and the back block can drop to not disturb puts into the required height of glass substrate action.
