Fig. 3 is the top plan that illustrates according to the grinding unit in the flat-panel monitor manufacturing system of the embodiment of the invention; Fig. 4 is in the flat-panel monitor manufacturing system that illustrates according to the embodiment of the invention, the top plan of the situation with panel from the grinding cell moving to the stock removal detecting unit; And Fig. 5 illustrates the block scheme that concerns according between the grinding unit in the flat-panel monitor manufacturing system of the embodiment of the invention, controller and the stock removal detecting unit.
To shown in Figure 5, can also comprise grinding unit 300, panel driving portion 500 and controller 700 as Fig. 3 according to the flat-panel monitor manufacturing system of the embodiment of the invention.
The coboundary 11 of 300 grinding panels, 10 first sides, grinding unit and the coboundary 13 and the lower limb 14 of the lower limb 12 and second side.At length, grinding unit 300 can comprise grinding platform 310, position detector 330 and sharpener 350.Panel 10 is arranged on the grinding platform 310.Position detector 330 is used to detect the position of the panel 10 that is arranged on the grinding platform 310.Sharpener 350 is used for when the grinding panel 10 left and when moving right along the detection position of panel 10.
As shown in Figure 4, panel driving portion 500 moves to the panel 10 of grinding the platform 160 of stock removal detecting unit 100 from grinding unit 300.
As shown in Figure 5, the stock removal information of the positional information of the panel 10 that controller 700 is detected by grinding unit 300 by exchange and the panel 10 that detected by stock removal detecting unit 100 is come the position of control panel 10 based on FEEDBACK CONTROL.
In other words, controller 700 can realize by the one or more processors that started by preset program, and can write preset program and carry out each step of method that is used to control the flat-panel monitor manufacturing system according to the embodiment of the invention.
Fig. 6 and Fig. 7 are the process flow diagrams of method that is used to control the flat-panel monitor manufacturing system that illustrates according to the embodiment of the invention.
With reference to Fig. 6, the method that is used to control the flat-panel monitor manufacturing system according to of the present invention will be described in more detail below.
In step S11, first detection signal that controller 700 receives according to the positional information of panel 10 from the position detector 330 that is arranged on the grinding unit 300.Particularly, when being arranged on next panel on the grinding platform 310, position detector 330 detects the positional information of panel 10.
In step S13, controller 700 is converted to first control signal with first detection signal.
In step S15, first control signal is stored in the storer (not shown) that is arranged on the controller 700.Particularly, if upgrade the positional information of next panel 10, first control signal that then will upgrade stores in the storer of current first control signal of deletion.
In step S17, when the panel 10 of grinding on grinding unit 300 was moved to the platform 160 that is arranged on stock removal detecting unit 100, controller 700 came control panel drive division 500 based on first control signal that is stored in the storer.Therefore, the panel of being supported by panel driving portion 500 (for example, by mechanical arm etc.) 10 can accurately be arranged on the platform 160 by panel driving portion 500.
The method according to this invention can also may further comprise the steps:
In step S21, second detection signal that controller 700 receives according to the stock removal information of panel 10 from first camera 111, second camera 112, the 3rd camera 131 and the 4th camera 132 that is arranged on stock removal detecting unit 100.Particularly, when being arranged on next panel on the platform 160, first camera 111, second camera 112, the 3rd camera 131 and the 4th camera 132 detect the stock removal information of panel 10.
In step S23, controller 700 is converted to second control signal with second detection signal.
In step S25, second control signal is stored in the storer.Particularly, if upgrade the stock removal information of next panel 10, second control signal that then will upgrade is stored in the storer of current second control signal of deletion.
In step S27, when the sharpener 350 grinding panels 10 by being arranged on grinding unit 300, controller is controlled the left/right amount of movement of sharpener 350 based on second control signal.Therefore, can come grinding panel 10 more accurately by the sharpener 350 that can left/right moves.
On the other hand, in said method, having described to carry out based on the positional information that is detected by position detector 330 comes first of control panel drive division 500 to handle (shown in Figure 6), carry out then based on controlling second of sharpener 350 amount of movements and handle (shown in Figure 7), carry out second processing (shown in Figure 7) before but can handle (shown in Figure 6) first by camera 111,112,131 and the 132 stock removal information that detect.
As mentioned above, according to the flat-panel monitor manufacturing system of the embodiment of the invention and the method that is used to control this flat-panel monitor manufacturing system can have the following advantages.
According to embodiments of the invention, can detect the coboundary of at least one side of panel and the stock removal of lower limb simultaneously.That is, can reduce stock removal detection time.As a result, can reduce overall average cycle length (TACT).
In addition, according to embodiments of the invention, can come the control panel position based on FEEDBACK CONTROL, this FEEDBACK CONTROL is controlled by the positions of panels information of grinding unit detection with by the panel stock removal information that the stock removal detecting unit detects by exchange.That is, because can come the control panel position, so grinding panel accurately based on FEEDBACK CONTROL.
Although described the present invention in conjunction with the current exemplary embodiments that is considered to practicality, should be appreciated that, the embodiment that the invention is not restricted to disclose, on the contrary, the present invention is used to cover the various changes in the spirit and scope that are included in claim and is equal to replacement.
