Test and Adjustment Process

A material handling manipulator is controlled by a sequence of instructions generated in response to system inputs. The process description which follows is divided into three sections.

The Part Selection routine selects the next work piece to be operated on and moves it to a work station.

The Test and Adjustment Routine executes a test or sequence of tests on the work piece, and performs interactive adjustment of a variable on the work piece such as a variable resistor.

The Instruction Generation Routine (IG) generates instructions for the manipulator based on function to be performed and previous motion. PART SELECTION ROUTINE (Fig. 2).

Step.

1 Start. Initiate all programs and equipment.

2 Set index to next part, assuming an "egg crate" or other

multiple unit presentation method, a register is used

to maintain the next sequential unit to be manipulated.

This would be the reentry point following completion

of previous part manipulation.

3 Has the last part in this lot been exercised? If so,

initiate necessary end of lot procedures.

4 Such as indexing a conveyor or triggering an alarm. If

not, proceed to step 5.

5 The physical coordinates of the location of the next

part would be determined by some algorithm, utilizing

known distances between parts.

6 The physical coordinates developed by step 5 are stored

in a communications area prior to initiating a program

branch to the Instruction Generation (IG) routine at

step 7.

8 Upon return from IG routine, the closer gripper command

would be issued through the IG routine at step 9. 10 Utilizing a sensing device the presence or absence of a part in the gripper would be detected. If no part were

present, a procedure in steps 11 and 12 would be utilized

to determine corrective action, such as initiating an end

of lot processing where short lots were common, or returning

to next part selection where occasional empty

containers are encountered. 13 Upon sensing a part in the gripper, the coordinates of the location of the tester receptacle would be transferred to

the instruction generation routine and a program branch

to the IG routine issued at step 14. 15 Upon completion of the part transfer from the delivery rack to the tester receptacle, the inputs from the tester

device are read to determine if a good connection was made.

If a good connection did not occur, corrective action would

be initiated. 18 A procedure would be established to improve the connection

in one or more ways; such as, removing and reinsertion,

application of additional insertion forces, etc.,

correction procedure (CP) Step 19. 16 Establish necessary parameters for test (17) and return. TEST AND ADJUST ROUTINE (Fig. 1)

Step 1 With the part to be tested firmly in the receptacle, the

tester sense lines are read by the data processing system.

An analog-to-digital conversion may be required.

2 The values read in from the tester are compared to the

desired values of the part.
