Description

Technical Field

[0001] This utility model relates to the field of diamond saw blade production technology, and specifically to a diamond saw blade testing system. Background Technology

[0002] Diamond saw blades require inspection during the production process. This inspection includes checking whether the side clearance of the diamond saw blade is up to standard, whether there are cracks on the front and back of the diamond saw blade. The current inspection method is manual sampling. Workers use calipers to check whether the side clearance is up to standard and rely on experience to check whether there are cracks on the front and back of the diamond saw blade. Because it is a sampling inspection, there may be defective products that cannot be detected, which will affect the quality of the finished product.

[0003] With the development of visual inspection systems, image deep learning defect detection technology has been applied to finished product inspection. Image deep learning defect detection technology is an advanced method that uses artificial intelligence to automatically identify product defects. Its core is to learn defect features through convolutional neural networks (CNNs) to achieve efficient quality inspection. During operation, the items to be inspected are photographed, and then the images are processed by a computer. Image deep learning defect detection technology is then used to automatically detect defects in the inspected items. Machine inspection efficiency is far higher than manual inspection, thus enabling large-scale batch inspection of diamond saw blades.

[0004] Therefore, there is an urgent need for a diamond saw blade testing system to achieve automatic testing of large quantities of diamond saw blades. Utility Model Content

[0075] The frequency converter is communicatively connected to the PLC controller 11.

[0076] This embodiment involves a large number of motors, solenoid valves, and frequency converters. The working principles of motors, solenoid valves, and frequency converters of the same type are consistent throughout this embodiment. The principle description will only cover the first appearance of this type of equipment. In this embodiment, the PLC controller 11 is communicatively connected to the host computer.

[0077] Control commands are issued through HMI module 12 during operation.

[0078] Diamond saw blade feeding: The diamond saw blade to be tested is placed on the feeding conveyor 3. The PLC controller 11 controls the frequency converter to work, which in turn powers the servo motor. The belt conveyor of the feeding conveyor 3 operates under the drive of the servo motor, conveying the diamond saw blade to the tail end. When the diamond saw blade reaches the tail end of the feeding conveyor 3, the infrared light emitted by the transmitter of the infrared photoelectric switch 13 is blocked by the diamond saw blade, and the receiver does not receive the signal. The input terminal of the PLC controller 11 becomes low level.

[0079] The diamond saw blade is transported to the rotary table: Then, the PLC controller 11 controls the material handling device 4 above the corresponding feed conveyor 3 to start. The servo motor of the material handling device 4 drives the linear guide rail 402, causing the slider to move the cylinder and magnetic chuck 401 above the diamond saw blade. The PLC controller 11 energizes the coil of the two-position three-way solenoid valve, changing the valve's conduction direction, causing the cylinder piston rod to extend and move the magnetic chuck 401 closer to the diamond saw blade. Next, the PLC controller 11 energizes the relay coil, causing the magnetic chuck 401 to magnetically attract the diamond saw blade. Then, the PLC controller 11 controls the cylinder to retract, and the servo motor drives the linear guide rail 402 in the opposite direction, transporting the diamond saw blade to the loading station of the rotary table 5.

[0080] The rotating worktable operates sequentially: PLC controller 11 controls the turntable servo motor 502 of the rotating worktable 5 to drive the table surface 501 to rotate, and sequentially sends the worktable rotating shaft 6 carrying the diamond saw blade to each testing station.

[0081] Frontal Crack Detection: In this embodiment, the camera module 14 uses a Keyence IV3 industrial camera. When the diamond saw blade reaches the frontal crack detection station, the first crack detection device 1 is activated. The PLC controller 11 controls the stepper motor to drive the slide module, adjusts the position of the camera module 14, and performs crack detection on the front of the diamond saw blade. The camera module 14 acquires the image of the diamond saw blade and uploads it to the host computer.

[0082] Diamond saw blade flipping: After the front crack inspection is completed, the rotary table 5 continues to rotate, sending the diamond saw blade to the flipping station. The PLC controller 11 controls the diamond saw blade flipping mechanism 7 to start. A two-position three-way solenoid valve causes the Y-axis cylinder 702 to move the X-axis cylinder 701 above the diamond saw blade. Then, the PLC controller 11 controls the X-axis cylinder 701 to extend its moving end, bringing the rotary cylinder 703 and the gripper 704 to the appropriate position. The gripper 704 grasps the diamond saw blade, and the PLC controller 11 controls the three-position five-way valve to operate, causing the rotary cylinder 703 to rotate 180° to flip the diamond saw blade. The flipped diamond saw blade is then placed back onto the rotary axis 6.

[0083] Reverse crack detection: After the diamond saw blade is flipped over, it arrives at the reverse crack detection station. The second crack detection device 2 performs crack detection on the reverse side of the diamond saw blade in a similar manner to the first crack detection device 1.

[0084] Side clearance detection: After the reverse crack detection is completed, the rotary table 5 delivers the diamond saw blade to the side clearance detection station. The side clearance detection equipment 10 is started, the stepper motor drives the slide module, adjusts the position of the grating displacement sensor 15, and detects the side clearance of the diamond saw blade. The detection data is transmitted to the PLC controller 11. The PLC controller 11 uploads the detection data to the host computer.

[0085] Diamond saw blade unloading: After the backlash detection is completed, the rotary table 5 delivers the diamond saw blade to the unloading station. The PLC controller 11 controls the material handling device 4 above the discharge conveyor 8 to move the diamond saw blade from the rotary table 5 to the discharge conveyor 8 in a similar manner to loading.

[0086] The host computer judges the parameters of the diamond saw blade. If the diamond saw blade is detected as defective, the PLC controller 11 controls the material handling device 4 to transport the diamond saw blade to the defective sorting table 9. The PLC controller 11 controls the belt conveyor of the discharge conveyor 8 to send the qualified diamond saw blade out of the detection system under the drive of the servo motor.

[0087] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
