Description

Technical Field

[0001] This utility model relates to the field of material gripping and releasing technology, specifically to an integrated circuit material gripping structure. Background Technology

[0002] In today's highly developed electronics manufacturing industry, SMT production lines resemble precisely operating assembly lines, continuously supplying various electronic products to the world. The SMT integrated circuit board loading device is undoubtedly one of the key hubs on this assembly line. It shoulders the crucial responsibility of accurately, efficiently, and continuously transporting the electronic components to be mounted to the corresponding pads on the circuit board, making it a true unsung hero in electronics manufacturing.

[0003] Compared to traditional manual loading methods, automated loading devices offer unparalleled advantages. Like a tireless high-speed runner, they are faster and more standardized, essentially pressing the "accelerator button" on the SMT production line. This significantly reduces the loading time for each circuit board, bringing downtime to near zero. The resulting increase in production efficiency is remarkable, and its powerful impact can be truly felt in large-scale electronics manufacturing plants. Once advanced loading devices are adopted, the number of circuit boards mounted per hour increases dramatically, potentially by dozens or even more compared to manual loading, providing a solid guarantee for companies to seize market opportunities.

[0004] Moreover, its precise positioning system acts like a pair of sharp eagle eyes, constantly locking onto the target; the stable conveyor mechanism is like a smooth track, ensuring the accuracy and stability of the circuit board during the placement process. Working in perfect harmony, they eliminate the root causes of quality problems such as incorrect placement and poor soldering caused by human factors (e.g., hand tremors, placement deviations), significantly improving the yield and reliability of electronic products and saving companies substantial costs associated with rework and scrap.

[0005] Existing integrated circuit board loading devices are too slow in picking up materials, which seriously affects production efficiency. In the fast-paced modern manufacturing industry, every second is crucial to cost and benefit, and there is a direct linear relationship between material flow speed and production efficiency.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 This utility model provides a technical solution:

[0027] An integrated circuit material gripping structure includes a gripping arm 1, with a feeding system motion component connected to the top of the gripping arm 1. A gripping head 2 is provided at the lower end of the gripping arm 1. An X-axis positioning structure and a Y-axis positioning structure are provided inside the gripping arm 1. The upper end of the gripping arm 1 can be connected to a lifting mechanism that drives the Z-axis movement, or the gripping arm 1 can have an automatic telescopic function. The gripping arm 1 can be moved by the system motion component to be directly above the material, and then the gripping head 2 is driven to move along the Z-axis to contact the material to be gripped. After gripping the material, the device will carry the material to the solder pad location for subsequent operations.

[0028] Furthermore, the material handling head 2 is provided with a clearance groove 3 corresponding to the positioning structure, and a high-precision positioning structure base block 4 is provided inside the material handling head 2. X-axis positioning structures and Y-axis positioning structures are provided on both sides of the high-precision positioning structure base block 4. The high-precision positioning structure base block 4 is fixed inside the material handling arm 1. The accuracy of the high-precision positioning structure base block 4 and its X-axis motion slide 5 and Y-axis motion slide 6 determines the accuracy of the X and Y axes positioning. It is not recommended to provide an integrated X-axis motion slide 5 and Y-axis motion slide 6 on the material handling arm 1. After prolonged use, the material will inevitably wear and deform, leading to a decrease in accuracy. The high-precision positioning structure base block 4 facilitates maintenance, and it is recommended to replace it directly when the accuracy does not meet the usage requirements.

[0029] Furthermore, an X-axis motion groove 5 is provided above the high-precision positioning structure base block 4, and a Y-axis motion groove 6 is provided below the high-precision positioning structure base block 4. The X-axis motion groove 5 and the Y-axis motion groove 6 are perpendicular to each other.

[0030] Furthermore, the X-axis positioning structure includes a servo motor 7, a gear 8, an X-axis positioning rack 9, and an X-axis connecting rod 10. A servo motor 7 is fixedly mounted on one side of the X-axis motion slide groove 5 on the high-precision positioning structure base block 4. A gear 8 is coaxially connected to the servo motor 7. An X-axis positioning rack 9 is slidably connected within the X-axis motion slide groove 5. The X-axis positioning rack 9 has teeth corresponding to those of the gear 8. The gear 8 meshes with the X-axis positioning rack 9. A vertically downward X-axis connecting rod 10 is located on one side of the X-axis positioning rack 9. The servo motor 7 on one side of the X-axis motion slide groove 5 on the high-precision positioning structure base block 4 starts rapidly, driving the coaxially tightly connected gear 8 to rotate at a uniform speed. Because the gear 8 is precisely meshed with the X-axis positioning rack 9 which is flexibly connected to the X-axis motion slide 5, as the gear 8 continues to rotate, the X-axis positioning rack 9 will slide smoothly along the X-axis direction in the slide 5. The X-axis connecting rod 10, which is vertically downward on one side of the X-axis positioning rack 9, will also move synchronously. This will precisely push the X-axis positioning moving block 15, which is corresponding to the X-axis connecting rod 10 on the lower side of the picking head 2, to move finely along the X-axis direction, thereby achieving high-precision positioning adjustment of the gripping position in the X-axis direction and ensuring the accuracy of the gripping position in the X-axis dimension.

[0031] Furthermore, the Y-axis positioning structure includes a servo motor 7, a gear 8, a Y-axis positioning rack 11, and a Y-axis connecting rod 12. A servo motor 7 is fixedly installed on one side of the Y-axis motion slide 6 below the high-precision positioning structure base block 4. A gear 8 is coaxially connected to the servo motor 7. The Y-axis positioning rack 11 is slidably connected within the X-axis motion slide 5. The Y-axis positioning rack 11 has teeth corresponding to those of the gear 8. The gear 8 meshes with the X-axis positioning rack 9. A vertically downward Y-axis connecting rod 12 is located on one side of the X-axis positioning rack 9. The principle of the Y-axis positioning structure is similar to that of the X-axis positioning structure, but Y-axis positioning and X-axis positioning can operate simultaneously without interference, accelerating material gripping speed. Furthermore, gripping materials from both axes provides more stable material holding and prevents material movement during transportation, loading, and unloading processes from affecting integrated circuit welding.

[0032] Furthermore, the material handling head 2 includes an X-fixed plate 13, a Y-fixed plate 14, an X-axis positioning moving block 15, a Y-axis positioning moving block 16, and a flexible pad 17. The X-fixed plate 13 and the Y-fixed plate 14 are connected to the lower side of the material handling head 2. The X-fixed plate 13 and the Y-fixed plate 14 correspond to the X-axis connecting rod 10 and the Y-axis connecting rod 12. The X-axis positioning moving block 15 and the Y-axis positioning moving block 16 are connected to the ends of the X-axis connecting rod 10 and the Y-axis connecting rod 12. A flexible pad 17 is provided between the X-fixed plate 13 and the Y-fixed plate 14. The X-axis positioning block 15 moves toward the X-fixed plate 13, and the X-axis positioning block 15 and the X-fixed plate 13 clamp one side of the material. Similarly, the Y-axis positioning block 16 moves toward the Y-fixed plate 14, and the Y-axis positioning block 16 and the X-fixed plate 13 clamp the other side of the material, thereby realizing material gripping. The flexible pad 17 plays a crucial role in buffering and protecting the material, effectively preventing damage to the material due to hard contact during gripping.

[0033] Working Principle: When it is necessary to grasp integrated circuit materials, after the system issues the instruction to grasp the integrated circuit materials, the grasping arm 1 first moves to above the area where the material is located under the drive of the motion component of the feeding system connected to the top. At this time, the grasping arm 1 makes precise lifting and lowering adjustments according to the height information of the material through the lifting device, so that the grasping head 2 is at a suitable height position, preparing for the subsequent grasping action. The high-precision positioning structure block 4 inside the grasping head 2 is the core component for achieving precise grasping. The carefully set X-axis positioning structure and Y-axis positioning structure on both sides will work together to start the X-axis positioning process and achieve high-precision positioning. The servo motor 7 on one side of the X-axis motion slide 5 on the structural base block 4 starts quickly, driving the coaxially tightly connected gear 8 to rotate at a constant speed. Because the gear 8 precisely meshes with the X-axis positioning rack 9, which is flexibly slidably connected within the X-axis motion slide 5, the X-axis positioning rack 9 slides smoothly along the X-axis direction within the slide 5 as the gear 8 continues to rotate. Simultaneously, the vertically downward X-axis connecting rod 10 on one side of the X-axis positioning rack 9 moves synchronously, thereby precisely pushing the X-axis positioning moving block 15, corresponding to the X-axis connecting rod 10, on the lower side of the picking head 2 to move finely along the X-axis direction, achieving a high-precision gripping position in the X-axis direction. Precision positioning adjustment ensures the accuracy of the gripping position in the X-axis dimension. Similarly, in the Y-axis positioning stage, the servo motor 7 on one side of the Y-axis motion slide 6 below the high-precision positioning structure block 4 immediately starts, driving the coaxial gear 8 to rotate and tightly mesh with the Y-axis positioning rack 11 in the Y-axis motion slide 6. This causes the Y-axis positioning rack 11 to slide smoothly along the Y-axis direction within the slide 6. The vertically downward Y-axis connecting rod 12 on one side of the Y-axis positioning rack 11 pushes the Y-axis positioning moving block 16 corresponding to the Y-axis connecting rod 12 on the lower side of the picking head 2 to move precisely along the Y-axis direction, successfully completing the precision positioning in the Y-axis direction. The precise positioning task, achieved through dual precision positioning along the X and Y axes, ensures that the X-fixed plate 13, Y-fixed plate 14, and the flexible pad 17 thoughtfully placed between them on the underside of the picking head 2 are accurately aligned with the integrated circuit material. The flexible pad 17 plays a crucial role in buffering and protecting the material, effectively preventing damage caused by hard contact during gripping. Finally, under the unified control of the picking arm 1, the picking head 2 successfully completes the gripping action of the integrated circuit material. Subsequently, the picking arm 1 moves the gripped material to the designated position according to system instructions, thus successfully completing the entire material gripping and transportation process.
