Description

Technical Field

[0001] The present invention relates to the technical field of quality inspection equipment, and in particular to an online multi-point lens recognition device for defective cast welding points. Background Art

[0002] Cast welding is a process of joining, welding, and inserting metals using a mold formed into a casting pattern. When two metal workpieces are cast-welded, a gap will inevitably appear at the contact point. The quality of the weld determines the stability of the welded connection. Poor weld contact can easily cause the weld to break, so weld inspection is necessary after the workpieces are cast-welded.

However, both single optical inspection and multiple manual inspections are inefficient and often result in unidentified and missed defects, leading to the risk of defective finished products.

When the mounting ring 642 rotates in the fixed ring 641, the movable steel ball 6423 rolls against the inner wall of the fixed ring 641 to ensure smooth rotation between the fixed ring 641 and the mounting ring 642.

[0032] The structural composition of the first detection member 64 is the same as that of the second detection member 65. The mounting rings 642 of the first detection member 64 and the second detection member 65 are coaxially arranged and fixedly connected by a fixing rod 66.

The driving motor drives the mounting ring 642 of the first detection member 64 through the rotating shaft 67 and the bevel gear 68. The mounting ring 642 of the first detection member 64 drives the mounting ring 642 of the second detection member 65 to rotate by the fixing rod 66. The first detection member 64 and the mounting ring 642 of the second detection member 65 rotate synchronously. The optical recognition camera 644 and the ultrasonic lens 645 on the top thereof rotate to scan and detect defective points on the cast weld surrounding the workpiece, and transmit the detection structure to the recognition and analysis terminal 7 through the wireless transmitter 646.

[0033] An installation cavity 6424 is provided inside the installation ring 642, and the installation cavity 6424 is concentrically arranged with the installation slot 6421. One end of the marking member 647 extends into the installation cavity 6424. The marking member 647 is used to mark the defective points of the workpiece casting welding after they are detected.

[0034] The marking part 647 includes a first electromagnet 6471 and a second electromagnet 6472 fixedly connected to the inner walls of the upper and lower ends of the installation cavity 6424, a cross rod 6473 fixedly connected between the opposite outer walls of the first electromagnet 6471 and the second electromagnet 6472, and a movable armature 6474 movably sleeved on the inner walls at both ends of the cross rod 6473, a return spring 6475 is wound around the outer wall of the cross rod 6473 between the movable armature 6474 and the first electromagnet 6471 and the movable armature 6474 and the second electromagnet 6472, and a movable connecting rod 6476 is movably connected to the outer wall of the movable armature 6474 away from the installation slot 6421, and the end of the movable connecting rod 6476 is movably connected to the marking pen 6477.

[0035] The end of the marking pen 6477 extends through the raised block 6478 on the inner wall of the mounting ring 642, and the marking pen 6477 is received in the guide channel 6479 inside the raised block 6478. When the reset spring 6475 maintains a normal relaxation state, the end of the marking pen 6477 is located at the end of the guide channel 6479. The marking pens 6477 corresponding to the first electromagnet 6471 and the second electromagnet 6472 are marked green and red respectively. Green indicates that there are no bad spots in the cast welding of the workpiece. On the contrary, red indicates that there are bad spots in the workpiece. The identification and analysis terminal 7 receives the detection data and After analysis and judgment, the identification and analysis terminal 7 selectively controls the circuits of the first electromagnet 6471 and the second electromagnet 6472 to connect. After one of the circuits of the first electromagnet 6471 and the second electromagnet 6472 is connected, it adsorbs the movable armature 6474. The movable armature 6474 moves the compressed reset spring 6475 and drives the movable connecting rod 6476 to deflect and move. The movable connecting rod 6476 pushes the marking pen 6477 out of the guide channel 6479. The marking pen 6477 makes corresponding fixed point marks on the workpiece of the internal ring when it rotates with the mounting ring 642.

[0036] Flexible pads 11 are evenly spaced and fixedly connected to the outer wall of the conveyor belt of the conveyor belt mechanism 1.

Cast-welded workpieces of different shapes are selectively placed in the square groove 12 and the circular groove 13. The flexible extrusion deformation of the flexible pad 11 clamps the workpiece, and the adsorption magnetic block 14 assists in adsorbing the workpiece, thereby ensuring its stability when the conveyor belt of the conveyor belt mechanism 1 transports the workpiece to be inspected, and avoiding the unstable placement of the workpiece to be inspected and affecting the detection of defective points.

[0037] An identification and analysis system 71 is provided inside the identification and analysis terminal 7. The identification and analysis system 71 includes a processing chip 711 for controlling operation and a data processing module 712 electrically connected to the processing chip 711, which is used for converting and processing data signals. The data processing module 712 is electrically connected to an Internet module 713, which is used for remote signal connection to the matrix lens assembly 6 for data reception. The processing chip 711 is electrically connected to a data recording module 714 for storing data. The processing chip 711 is also electrically connected in turn to an online analysis module 715 for analyzing and processing detection data, and an imaging module 716 for forming an analysis image. The imaging module 716 forms an image of the detection point of the workpiece weld and projects it onto a display screen.

[0038] Specifically, the conveyor belt of the conveyor mechanism 1 conveys the workpiece to be inspected to the bottom of the matrix lens assembly 6. The matrix lens assembly 6 is suspended above the conveyor belt of the conveyor mechanism 1 after being lowered by the lifting seat 4, and is looped around the outside of the cast-welded workpiece at the top of the conveyor belt of the conveyor mechanism 1. The driving motor drives the mounting ring 642 of the first detection member 64 through the rotating shaft 67 and the bevel gear 68. The mounting ring 642 of the first detection member 64 drives the mounting ring 642 of the second detection member 65 to rotate by the fixed rod 66. The first detection member 64 and the mounting ring 642 of the second detection member 65 rotate synchronously. The optical recognition camera 644 and the ultrasonic lens 645 on the top form a cylindrical matrix to wrap the cast-welded workpiece. When rotating, the cast weld seam surrounding the workpiece is scanned for defective points and the detection structure is transmitted to the recognition and analysis terminal 7 through the wireless transmitter 646. After the Internet module 713 receives the detection data, the data processing module 712 performs signal processing, and then the imaging module 716 performs according to the scanning of the optical recognition camera 644 and the ultrasonic lens 645. Imaging processing, the online analysis module 715 performs online analysis based on the imaging data to determine whether there are defective spots in the cast-welded workpiece. The double-layer cylindrical detection lens matrix is ​​used to perform rapid all-round and scanning imaging detection on the weld defective spots of the cast-welded workpiece. Adjacent detection lenses form a re-inspection comparison to improve the accuracy of confirming the defective spots. After the processing chip 711 receives the detection data and performs analysis and judgment, the processing chip 711 selectively controls the circuits of the first electromagnet 6471 and the second electromagnet 6472 to be connected. After the circuits of the first electromagnet 6471 and the second electromagnet 6472 are selectively connected, it adsorbs the movable armature 6474. The movable armature 6474 moves the compressed reset spring 6475 and drives the movable connecting rod 6476 to deflect and move. The movable connecting rod 6476 pushes the marking pen 6477 out of the guide channel 6479. The marking pen 6477 marks the workpiece of the internal ring sleeve accordingly when it rotates with the mounting ring 642, thereby realizing directional distinction after the detection of defective spots in the cast-welded workpiece, which is convenient and practical.
