The working principle of the invention is as follows:
the plate is carried onto the conveying roller 1, the driving box 2 drives the conveying roller 1, the conveying roller 1 rotates and conveys the plate, the material pushing cylinder 5 blocks the plate conveyed by the conveying roller 1, before the plate is not detected, the plate is blocked in the detecting box 3, two ends of the plate are positioned on the lower clamping plate 6, the sensor detects whether the plate exists or not, the control system controls the material clamping module 8 according to the feedback of the sensor after detecting the plate exists, the material clamping module 8 drives the upper clamping plate 7 and the lower clamping plate 6 to move relatively, the upper clamping plate 7 and the lower clamping plate 6 are matched with each other to clamp the plate, the lifting of the lower clamping plate 6 enables the plate to be separated from the conveying roller 1, then the moving module 11 drives the plate to lift through the bottom plate 14 and the bearing plate 9, the plate is far away from the conveying roller 1, after a certain distance of lifting, the cylinder rods of the bending cylinders 15 extend, the two bending cylinders 15 are mutually matched to press the plate, the plate is bent, the photographing module 13 photographs the bent plate and transmits the photographed plate to the control system, the control system processes the photographing and obtains the arc length and the radian of the bent plate, and finally the bending angle of the plate is calculated; after the plate is cracked due to bending, the control system analyzes the maximum pressure and the maximum bending angle which can be born by the plate according to the picture transmitted by the camera module 13.
When the hardness of the plate is not required to be detected, the output end of the cylinder rod of the pressurizing cylinder 10 does not extend, when the hardness of the plate is required to be detected, the plate is located on the lower clamping plate 6, the upper clamping plate 7 and the lower clamping plate 6 do not clamp the plate, the pressurizing cylinder 10 is a hydraulic cylinder, the pressurizing cylinder 10 works under the control of the control system, the cylinder rod extends out and pushes the pressurizing block to press down, the pressurizing block is abutted to the plate, the pressure sensor is located on the pressurizing block, the plate is continuously pressurized along with the pressurizing block, the pressure value detected by the pressure sensor continuously rises, and when the pressure value suddenly decreases, the control system records the current pressure value and obtains the maximum compression resistance value and the hardness which can be born by the plate. After the detection is completed, the pressurizing cylinder 10 drives the pressurizing block to reset.
When the bonding firmness of the plates (composite plates) is required to be detected, the upper clamp plate 7 and the lower clamp plate 6 clamp the plates first, then the moving module 11 lifts the plates, then the negative pressure system extracts air in the suction nozzle 19 through the pipeline, the upper clamp plate 7 and the lower clamp plate 6 are adsorbed on the upper end face and the lower end face of the plates, the clamping module 8 enables the upper clamp plate 7 and the lower clamp plate 6 to be far away, along with the opposite movement of the upper clamp plate 7 and the lower clamp plate 6, the torsion moment detected by the torque sensor is continuously increased and finally maintained at a certain value, the image pickup module 13 performs image acquisition on the plates, the control system analyzes the images, the control system records the value transmitted by the torque sensor when the composite layers of the plates are pulled apart, and the connection firmness of the plates after the plates are compounded is known through the recorded torsion moment value.
When the bending cylinder 15 is not in operation, the cylinder rod can rotate freely, and the cylinder rod is the rotation center of the bearing plate 9. After the upper clamping plate 7 and the lower clamping plate 6 clamp the plate, when the torsion degree of the plate is required to be detected, the driving motor drives the driving gear 20 to rotate, the driving gear 20 drives the bearing plates 9 to rotate through teeth, the rotation directions of the two bearing plates 9 are opposite, the two bearing plates 9 twist the plate through the clamping jaw mechanism, the angle sensor detects the rotation angle of the driving gear 20 and transmits the rotation angle to the control system, and when the shooting module 13 shoots a picture of the cracking of the plate, the control system calculates and processes data transmitted by the angle sensor in the two bottom plates 14 to obtain the torsion angle of the plate during the cracking.
When the flatness (namely, pits and protrusions) of the surface of the plate is required to be detected, the upper clamping plate 7 and the lower clamping plate 6 clamp the plate, then the movable module 11 lifts the plate, then the cylinder rod of the lower pressing cylinder 22 stretches out and drives the detection shell 17 to descend, the detection shell 17 is close to the surface of the plate but is not in contact with the surface, the guide wire 23 protrudes out of the middle position of the detection shell 17 to prop against the surface of the plate, the guide wire 23 is pushed back into the detection shell 17 by the plate, two ends of the guide wire 23 protrude outwards on a rotating ball to match with the shape change of the guide wire 23, the upper module 12 and the sliding rail sliding block are matched with each other to drive the supporting plate 16 to move, the guide wire 23 detects the surface of the plate, when the guide wire 23 meets the pits, the guide wire 23 temporarily loses the limit of the resistance of the plate, the guide wire 23 deforms under the action of self elastic force and stretches into the pits, when the guide wire 23 meets the protrusions, the guide wire 23 is pushed into the detection shell 17 again, the detection shell 17, the guide wire 23 deforms, voltage is generated according to the positive voltage electrical effect, and when the signal detection circuit of the control system receives a voltage signal, the signal detection circuit of the control system detects the position of the plate according to the output of the upper module 12 and/or the position of the plate, the plate is detected, and the flatness is achieved. After the detection is completed, the upper module 12 drives the supporting plate 16 to reset, and the lower pressure cylinder 22 drives the detection shell 17 to reset.
When it is required to detect whether a hollow position (such as a hollow position generated by glue smearing problem of a composite board) exists in the board, the detection circuit applies a high-frequency pulse voltage to the guide wire 23, according to the inverse piezoelectric effect, the guide wire 23 generates high-frequency swing and continuously impacts on the surface of the board to enable the board to vibrate, if the hollow position exists in the board, the sound wave generated by the hollow position of the board is different from the sound wave generated by the solid position, the echo pickup 24 picks up and analyzes the sound wave generated by the board, and transmits the analysis result to the control system, the control system records the data of the board with the hollow space according to the result transmitted by the echo pickup 24, the upper module 12 drives the detection shell 17 to detect the whole board, and the control system obtains the position with the hollow space on the board according to the output turns of the motor in the upper module 12. After the detection is completed, the upper module 12 drives the supporting plate 16 to reset, and the lower pressure cylinder 22 drives the detection shell 17 to reset.
When various performance tests are carried out on the plates, the plates of different types conveyed by the conveying roller 1 can be clamped and replaced according to the test requirements. After the flatness and/or torsion and/or bending degree of the plate are detected, the moving module 11 moves the lower part of the plate to enable the lower clamping plate 6 to fall into the ladder, then the upper clamping plate 7 and the lower clamping plate 6 release the plate, the cylinder rod of the ejection cylinder 5 is retracted, and the plate moves out of the detection box 3 under the conveying of the conveying roller 1. After the plate moves out of the detection box 3, the cylinder rod of the ejection cylinder 5 stretches out again to intercept the next plate.
