4.1.4. Gun search movement by gun type

 

4.1.4.1.Servo-gun

 

The gun search function of servo-gun is initially set to reflect the share of the contribution of fixed tip and moving tip to the total tip consumption by 50% each. Therefore, the consumption can be calculated by using gun search 1 only. Refer to gun search 2 descriptions for calculating consumption of fixed tip and moving tip.

 

If the value of 『moving tip consumption/total consumption(%)』 is “0”, it is necessary to operate gun search 2; if the set value is not “0”, total consumption owing to gun search 1 operation will be divided according to the set ratio.

 

(1)   Gun search1

 

This measures the total tip consumption by squeezing the fixed tip with the moving tip.

 

S1    MOVE P,S=60%,A=1,T=1  ‘Move to the location of gun search 1 operation         GUNSEA GN=1,SE=1,PR=100,SP=10  ‘Gun search 1 operation         END

 

Figure 4.1 Gun search 1

 

①    Move to the record location of step.

 

②    Squeeze the fixed tip using the moving tip until the setting of squeeze force is achieved.

 

③    Measure total tip consumption, and execute opening when squeeze alignment is detected.

Previous tip consumption = Squeeze alignment detecting location - Gun search 1 reference location

 

④    Open up the record location of step.

 

⑤    Spilt total consumption measured in the ratio of moving tip and fixed tip as shown in the picture below, when operating Gun Search 1 only. (Default is 50:50)

 

Figure 4.2 Calculation of consumption using only Gun Search 1

 

(2)   Gun search 2  

  

This measures the moving tip consumption. It can be measured using a method based on squeeze force, or a method based on an external signal.

 

l Method based on squeeze force

 

Squeeze the calibration jig using the moving tip, and measure the moving tip consumption.

 

S1    MOVE P,S=60%,A=1,T=1  ‘Move to the location of gun search 1 operation         GUNSEA GN=1,SE=1,PR=100,SP=10  ‘Gun search 1 operation S2    MOVE P,S=60%,A=1,T=1  ‘Move to the location of gun search 1 operation         GUNSEA GN=1,SE=2,PR=100,SP=10  ‘Gun search 2 operation         END

 

 

Figure4.3 Gun search 2 based on squeeze force

 

①    Move to the record location of step.

 

②    Squeeze the search calibration jig using a moving tip until squeeze force is set.

 

③    Measure the moving tip consumption, and execute opening operation when squeeze alignment is detected.

Moving tip consumption = Squeeze alignment detecting location – Reference location of Gun Search 2 based on squeeze force

Fixed tip consumption = Total consumption detected by Gun Search1 - consumption of moving tip

 

④    When opening is complete, the consumption of the moving tip and the fixed tip will be updated.

 

l Method based on an external signal

 

Measure the moving tip consumption of by moving the moving tip to a location where a sensor is placed, and detecting the sensor input.

 

S1    MOVE P,S=60%,A=1,T=1  ‘Move to the location of gun search 1 operation         GUNSEA GN=1,SE=1,PR=100,SP=10  ‘Gun search 1 operation S2    MOVE P,S=60%,A=1,T=1 ‘Move to the location of gun search 2 operation         IGUNSEA GN=1,SP=10.0,DI=1 ‘Gun search 2 operation         END

 

 

Figure 4.4 External signal input Gun Search2

 

①    Move to the record location of step.

 

②    The moving tip will approach in search speed to switch the phototube contact signal.

 

③    Measure the moving tip consumption, and execute opening when a signal is detected in the phototube.

Moving tip consumption = External signal detecting location – Reference location of Gun Search 2 based on external signal input

Fixed tip consumption = Total consumption detected by Gun Search 1 - Moving tip consumption

 

④    When opening is complete, the consumption of the moving tip and the fixed tip will be updated.

 

4.1.4.2.EQless-gun

 

EQless-gun only controls the fixed tip consumption, so the Gun Search function measures the fixed tip consumption.

 

S1    MOVE P,S=60%,A=1,T=1  ‘Move to the location of gun search operation         EGUNSEA GN=3,SP=10.0,,SD=100,DI=1  ‘Gun search operation         END

 

 

Figure 4.5 EQless-Gun Search

 

(1)   Move to the record location of step.

 

(2)   Fixed tip will approach in search speed to switch the phototube contact signal.

 

(3)   Measure the fixed tip consumption and execute opening when a signal is detected in phototube

Fixed tip consumption = Sensor detecting location – Record location of Gun search

 

(4)   When opening is complete, consumption of the fixed tip will be updated.
