Therefore, the whole measuring process is operated by the manipulator controlled by the control system 6 from mechanical equipment, and accurate control is realized. In addition, the purpose of accurate measurement is further realized by combining the matching of the feeding frame, the pressing mechanism and other parts.
In addition, the application also provides a method for precisely measuring the length and the width of the bipolar plate of the fuel cell by using the device for precisely measuring the length and the width of the polar plate of the fuel cell, which comprises the following steps:
and (4) feeding. Before loading, the control system controls 6 the loading frame 1 to adjust the X-axis module 11 and the Y-axis module 12, and moves the X-direction guide rod assembly 114 and the Y-direction guide rod assembly 124 to the maximum opening position. And an operator places the polar plate 10 to be measured on the accommodating and adjusting position of the polar plate of the feeding frame 1. Then, the X-direction guide rod assembly 114 and the Y-direction guide rod assembly 124 move inwards to push the polar plates 10 until the polar plates 10 to be tested on the accommodating adjustment position are placed in order.
And secondly, taking materials. The manipulator 2 uses the upper pressing plate 41 and the sucker component 3 to suck a polar plate 10 to be detected from the feeding frame 1 under the control of the control system 6, and drives the polar plate 10 to the table top 8 of the lower pressing plate and aligns to the lower pressing plate 42 on the lower pressing plate.
And thirdly, pressing. The manipulator 2 is controlled by the control system 6 to inflate through the leather bag gripper 43 to press the upper pressing plate 41, the sucker assembly 3, the pole plate 10 and the lower pressing plate 42 together. The polar plate 10 between the upper pressing plate 41 and the lower pressing plate 42 is pressed flatly by the volume expansion extrusion of the inflated leather bag, so that the measurement error caused by the warping of the polar plate is prevented.
And fourthly, measuring the length. The manipulator 2 moves with the upper pressure plate 41, the sucker assembly 3, the pole plate 10 and the lower pressure plate 42 to the length measuring instrument 51 to measure the length under the control of the control system 6. Before the measurement, the two length-measuring brackets 512 move with the slider 513 toward both ends of the length slide 511. The robot 2, under the control of the control system 6, transports the plate 10 between the two length slides 511, perpendicular to the measuring direction. The length measuring carriage 512 then moves towards the middle to measure the length of the plate 10.
Since the position of the plate 10 between the upper pressing plate 41 and the lower pressing plate 42 is not necessarily very accurate, there will always be a certain error, so that the manipulator 2 swings the plate back and forth by a certain angle (+ -5 °) perpendicular to the measuring direction during measurement to obtain multiple sets of measured values. The minimum value is selected from the multiple groups of measured values, namely the measured length value.
Width measurement. After the length measurement is finished, the manipulator 2 rotates by 90 degrees under the control of the control system 6 together with the upper pressing plate, the sucker assembly, the pole plate and the lower pressing plate to move to the width measuring instrument 52 for measuring the width. Before measurement, the two width measurement brackets 522 move toward both ends of the width slide rail 521 along with the slider 523. The manipulator 2 transports the plate 10 between the two width slide rails 521, perpendicular to the measuring direction, under the control of the control system 6. The width measuring carriage 522 is then moved towards the middle to measure the width of the plate 10. Also to ensure accuracy, the robot 2 swings the plate back and forth at an angle perpendicular to the measurement direction during measurement to obtain multiple sets of measurements. And selecting the minimum value from the multiple groups of measured values as the measured width value.
Sixthly, the manipulator 2 conveys the lower pressing plate to the table top of the lower pressing plate after the width measurement is finished under the control of the control system 6, and the lower pressing plate is separated from the upper pressing plate through deflation of the leather bag gripper.
The polar plate is sent back to the feeding frame by the mechanical arm; the operator removes the plate.
