Description

Technical Field

[0001] This utility model relates to the field of patch technology, and in particular to a high-precision patch positioning device. Background Technology

[0002] Surface mount technology (SMT) is a type of electronic component widely used in the manufacturing process of modern electronic products. Compared to traditional through-hole mounting technology, SMT technology allows electronic components to be directly mounted on the surface of a printed circuit board (PCB), greatly improving the space utilization and integration of the PCB. It also supports automated production, improving production efficiency and product consistency. With the development of technology, electronic products are moving towards miniaturization, lightweighting, and multifunctionality, which places higher demands on SMT technology, especially on the accuracy of component positioning. In SMT processes, accurately placing the component in the predetermined position is one of the key steps to ensure the quality of the final product. High-precision positioning not only affects the functionality of electronic devices but also relates to the stability and reliability of the entire system. Inaccurate component positioning can lead to problems such as poor electrical connections, performance degradation, and even equipment failure. Existing component positioning devices involve manually holding the component with tweezers and placing it on the workpiece. This method is not only prone to deviations but also slow and time-consuming.

[0003] Therefore, a high-precision patch positioning device needs to be designed to solve the above-mentioned technical problems. Utility Model Content

[0008] As a further preferred option, it also includes a supplementary light, which is fixedly connected to the rear side of the mounting plate.

[0009] As a further preferred embodiment, it also includes a fixed shell, an anode plate, a cathode plate, and a dust collection frame.

[0011] Beneficial effects: 1.

The conveyor belt assembly 2 is installed in the middle of the fixed plate 1. First electric slide rails 3 are installed on both the front and rear sides of the fixed plate 1. First sliders 4 are slidably connected to both first electric slide rails 3. A gantry frame 5 is fixedly connected between the two first sliders 4. A second electric slide rail 6 is installed on the right side of the gantry frame 5. A second slider 7 is slidably connected to the right side of rail 6. A third electric slide rail 8 is installed to the right side of the second slider 7. A movable frame 9 is slidably connected to the right side of the third electric slide rail 8. A scanner 10 is fixedly connected to the right side of the movable frame 9. The first electric slide rail 3 and the second electric slide rail 6 are electrically connected to the scanner 10. An electric suction cup 11 is installed at the bottom of the movable frame 9. A laser rangefinder 12 is provided on the front side of the electric suction cup 11. The laser rangefinder 12 is electrically connected to the third electric slide rail 8 and the electric suction cup 11. A mounting frame 13 is bolted to the upper right side of the fixed plate 1. A feeding frame 14 is slidably connected to the inner side of the mounting frame 13.

[0022] like Figure 4 As shown, it also includes a handle 15, which is fixedly connected to the front side of the feeding frame 14.

[0023] like Figure 1 and Figure 2As shown, it also includes a display screen 16, which is installed between the top of the fixing plate 1 and the mounting bracket 13. The first electric slide rail 3, the second electric slide rail 6, the third electric slide rail 8, the conveyor belt group 2, the scanner 10, the electric suction cup 11 and the laser rangefinder 12 are electrically connected to the display screen 16.

[0024] like Figure 1 and Figure 2 As shown, it also includes a fill light 17, which is installed on the rear side of the inside of the fixing plate 1.

[0025] like Figure 5 As shown, it also includes a fixed shell 18, an anode plate 19, a cathode plate 20, and a dust collection frame 21. The fixed shell 18 is fixedly connected to the upper right side of the fixed plate 1. The anode plate 19 is fixedly connected to the middle inner side of the fixed shell 18. The cathode plate 20 is fixedly connected to both the front and rear sides of the inner side of the fixed shell 18. The dust collection frame 21 is slidably connected to both the front and rear sides of the lower inner side of the fixed shell 18. The dust collection frame 21 on the same side is located directly below the cathode plate 20. The anode plate 19 and the cathode plate 20 are electrically connected to the display screen 16.

[0026] like Figure 6 As shown, it also includes a fixing block 22, a support plate 23 and a spring 24. The front and rear sides of the fixing plate 1 are each connected to two fixing blocks 22 by bolts. The lower part of each of the four fixing blocks 22 is slidably connected to a support plate 23. Each support plate 23 and the fixing block 22 are respectively fixedly connected to two springs 24.

[0027] When this device is needed to assist in the placement of components, first pull the feed frame 14 forward using handle 15, place the component inside the feed frame 14 (multiple components can be placed), and then push it back to reset it. Then, start the conveyor belt assembly 2, anode plate 19, and cathode plate 20 via display screen 16. Place the workpiece to the right of the conveyor belt assembly 2, which will move the workpiece to the left. As the workpiece moves, the cathode plates 20 on both sides will collect dust from the workpiece. After moving a certain distance, stop the conveyor belt assembly 2, anode plate 19, and cathode plate 20 via display screen 16. The dust on the cathode plates 20 will fall into the dust collection frames 21 on both sides. The operator can slide the dust collection frames 21 towards the center to remove them for cleaning and then reset them. Start the first electric slide rail 3 and the second electric slide rail 6 and the scanner via display screen 16. Instrument 10 allows operators to observe the placement operation in real time via display screen 16. The first electric slide rail 3 drives the second electric slide rail 6 to move left and right, while the second electric slide rail 6 drives the scanner 10 and electric suction cup 11 to move back and forth. The scanner 10 scans the position of the placement piece within the feed frame 14 and transmits the data to the first electric slide rail 3 and the second electric slide rail 6 to accurately locate the placement piece. Then, the third electric slide rail 8, suction cup, and laser rangefinder 12 are activated via display screen 16. The third electric slide rail 8 drives the electric suction cup 11 to move downward. While the electric suction cup 11 moves downward, the laser rangefinder 12 monitors the distance between the electric suction cup 11 and the workpiece in real time. When the suction cup contacts the placement piece, it holds the piece in place. The laser rangefinder 12 transmits the information to the third electric slide rail 8, which then drives the suction cup to move upward and reset.

[0028] Then, the scanner 10, the first electric slide rail 3, and the second electric slide rail 6 are activated via the display screen 16 to precisely position the workpiece. Next, the laser rangefinder 12, the electric suction cup 11, and the third electric slide rail 8 are activated. The third electric slide rail 8 moves the electric suction cup 11 downwards. Simultaneously, the laser rangefinder 12 monitors the distance between the electric suction cup 11 and the workpiece in real time. When the suction cup contacts the workpiece, the laser rangefinder 12 transmits the information to the electric suction cup 11, and the electric suction cup 11 no longer holds the patch, allowing the patch to adhere to the workpiece. On the component, the third electric slide rail 8 is activated via the display screen 16 to drive the suction cup to move upward and reset. If the light is dim, the supplementary light 17 can be activated via the display screen 16 to provide supplementary light to the conveyor belt group 2, making the positioning of this device more accurate. This device uses the support plate 23 and spring 24 to reduce the force generated during operation, making it more stable. Finally, the first electric slide rail 3, the second electric slide rail 6, the third electric slide rail 8, the scanner 10, the electric suction cup 11, and the laser rangefinder 12 can be turned off via the display screen 16.
