Description

Technical Field

[0001] This utility model relates to the field of visual positioning technology for perimeter frames, and in particular to a visual positioning device for perimeter frame production. Background Technology

[0002] A frame is a structural element used in industrial manufacturing to fix, support, or protect core components. It is commonly found in fields such as electronic equipment, automobiles, and machinery. It is usually made of metal (such as aluminum alloys or steel) or engineering plastics and has high rigidity, precise positioning, and protective functions. In frame production, visual positioning technology uses industrial cameras to capture features such as the frame edges and holes to enable more precise positioning operations.

[0003] Existing perimeter vision positioning uses a high-resolution industrial camera with a precision optical lens to capture the perimeter's outline, hole positions, and other features in real time through machine vision algorithms. The image data is then converted into mechanical coordinates using coordinate transformation technology.

[0004] However, after visual positioning, it is not possible to correct the inaccurate position of the enclosure. As a result, the enclosure position will be inaccurate during subsequent positioning, which will lead to a decrease in the accuracy of processing, as well as a decrease in processing efficiency and yield in reality. This is not conducive to the wider operation and use of the equipment in practice.

[0005] Therefore, this application provides a visual positioning device for frame production to meet the requirements. Utility Model Content

[0031] Please see Figure 3 A visual positioning device for frame production includes a conveyor frame 1. A correction assembly 5 is disposed on the left side of the lower surface of the conveyor frame 1. The correction assembly 5 includes an L-shaped plate 501, a servo motor 502, a connecting shaft 503, a first gear 504, a bidirectional gear plate 505, and a second gear 506. The top of the L-shaped plate 501 is fixedly connected to the bottom of the conveyor frame 1. The top of the servo motor 502 is fixedly installed to the bottom of the L-shaped plate 501. One end of the connecting shaft 503 is fixedly connected to one end of the output shaft of the servo motor 502. The interior of the first gear 504 is fixedly connected to the outer surface of the other end of the connecting shaft 503. One side of the bidirectional gear plate 505 is fixedly connected to the first gear 504. The outer surfaces of gear 2 506 mesh with the other side of the bidirectional toothed plate 505. The upper surface of the bidirectional toothed plate 505 is in contact with the lower surface of the conveyor frame 1. The upper surface of gear 2 506 is in contact with the lower surface of the conveyor frame 1. A rotating rod 507 is fixedly installed inside gear 2 506. The outer surface of the rotating rod 507 is rotatably connected to the inner wall of the conveyor frame 1. A correction plate 508 is fixedly installed on the outer surface of one end of the rotating rod 507. The lower surface of the correction plate 508 is in contact with the upper surface of the conveyor frame 1. A limit slider 509 is fixedly installed on the lower surface of the conveyor frame 1. The interior of the limit slider 509 is slidably connected to the outer surface of the bidirectional toothed plate 505.

[0032] Specifically, when the servo motor 502 drives the gear 504 to rotate, it can drive the bidirectional gear plate 505 to move linearly. When the bidirectional gear plate 505 moves linearly, it can drive the gear 506 to rotate. The gear 506 drives the rotating rod 507 to rotate on the inner wall of the conveyor frame 1, which in turn drives the correction plate 508 to rotate. The lower surface of the correction plate 508 is in contact with the upper surface of the conveyor frame 1. When the frame deviates during the conveying of the frame on the conveyor frame 1, the rotation of the correction plate 508 can correct the frame, thus ensuring the accurate position of the frame during the conveying process.

[0033] Please see Figure 4 A positioning component 6 is provided on the right side of the upper surface of the conveyor frame 1. The positioning component 6 includes an extension block 601, an electric telescopic rod 602, a T-shaped slider 603, a crossbar 604, a positioning plate 605, and a screw 606. The bottom of the extension block 601 is fixedly installed to the right side of the top of the conveyor frame 1. One end of the electric telescopic rod 602 is fixedly installed to the inner wall of the extension block 601. The front of the T-shaped slider 603 is fixedly connected to the other end of the electric telescopic rod 602. The front of the crossbar 604 is fixedly connected to the back of the T-shaped slider 603. The front of the positioning plate 605 is fixedly connected to the back of the crossbar 604. The outer surface of the screw 606 is rotatably connected to the inner wall of the positioning plate 605. A turning block 607 is fixedly installed at one end of the screw 606. A positioning plate 608 is threadedly connected to the outer surface of the screw 606.

[0034] Specifically, one end of the electric telescopic rod 602 is fixed to the inner wall of the extension block 601. Utilizing the precise control of the telescopic length and speed of the electric telescopic rod 602, it can adapt to different widths of the enclosure for positioning operations. When the screw block 607 is rotated, the screw 606 can rotate within the positioning plate 605. When the screw 606 rotates, the positioning plate 608 moves along the axial direction of the screw 606. Utilizing the self-locking and precision of the threaded transmission, the distance between the positioning plate 608 and the positioning plate 605 can be precisely adjusted, thereby adapting to the positioning requirements of enclosures of different sizes and achieving precise positioning of the enclosure.

[0035] Please see Figure 1 and Figure 2 Support frames 2 are fixedly installed on both sides of the lower surface of the conveyor frame 1. A conveyor belt 3 is installed inside the conveyor frame 1. A vision component 4 is installed on the left side of the upper surface of the conveyor frame 1. The vision component 4 includes a shooting bracket 401, a mounting block 402 and a vision camera 403. The lower surface of the shooting bracket 401 is fixedly installed to the upper surface of the conveyor frame 1. The top of the mounting block 402 is fixedly installed to the bottom of the shooting bracket 401. The upper surface of the vision camera 403 is fixedly connected to the lower surface of the mounting block 402.

[0036] Specifically, the vision component 4 is installed on the left side of the upper surface of the conveyor frame 1. During the conveying process of the enclosure, the vision camera 403 can capture images of the enclosure in real time and transmit the image information to the subsequent control system for analysis and processing. The support frame 2 provides stable and reliable support for the conveyor frame 1. The conveyor belt 3 can operate continuously and smoothly under power drive, realizing the automatic conveying function of the enclosure.

[0037] Working principle: During use, the vision camera 403 first acquires images and detects the position of the frame on the conveyor belt 3. When a deviation in the frame position is detected, the equipment activates the correction component 5 for automatic adjustment. First, the servo motor 502 is driven by an external power source, which drives the connecting shaft 503 to rotate the gear 1 504. Through meshing transmission with the bidirectional toothed plate 505, the gear 2 506 is driven to rotate synchronously, thereby causing the correction plate 508 at one end of the rotating rod 507 to change angle, pushing the frame to the correct position. The limiting slider 509 limits the position of the bidirectional toothed plate 505 during movement. After the correction is completed, when positioning the frame, the electric telescopic rod 602 of the positioning component 6 can be used to push the T-shaped slider 603 and the crossbar 604 to move as a whole, causing the positioning plate 1 605 to abut against one side of the frame. At the same time, the position of the positioning plate 2 608 is adjusted by rotating the screw 606 to achieve precise clamping and positioning of the frame.
