Description

Technical Field

[0001] This utility model relates to a nail feeding slide structure for a nameplate welding robot system, belonging to the field of mechanical equipment technology. Background Technology

[0002] In the steel production and processing industry, nameplates, as crucial components identifying key information such as steel specifications, materials, and production details, require welding as a necessary step before the steel leaves the factory. Currently, the welding of steel nameplates in the market is still mainly done manually. This method suffers from significant problems due to its repetitive and monotonous nature. Operators are subjected to long-term, monotonous, and repetitive labor, resulting in high labor intensity and unstable welding quality due to human fatigue. This makes it difficult to meet the dual requirements of efficiency and quality in modern steel production.

[0003] To address the drawbacks of manual welding, a robotic nameplate welding system can automate the welding of nameplates by enabling real-time transmission of printed information, real-time laser marking, automatic nail and nameplate removal, and visual positioning and recognition. Implementing such a system effectively improves the automation level of steel nameplate welding, enhances the working environment for operators, reduces labor intensity, optimizes personnel allocation, and increases overall production efficiency, making it a crucial direction for upgrading steel nameplate welding processes.

[0004] However, in existing conventionally designed robotic welding nameplate systems, the nail feeding slide structure, as the core component for nail transmission, directly impacts the overall system's production efficiency due to its operational stability. Long-term practical experience has revealed that existing nail feeding slide structures frequently experience nail jamming after a period of use, severely restricting production continuity and efficiency. Analysis indicates that the main causes of nail jamming include: the small gaps between the pressure blocks on both sides of the nail feeding slide and the slide itself, allowing dust from the environment to accumulate in these gaps over time; and wear and tear from equipment operation leading to decreased component fit precision, further narrowing the gaps or creating irregular protrusions. This makes it easy for welding nails to get stuck in these gaps or worn areas during transmission, preventing them from reaching the nail pick-up point on the welding torch. This results in system downtime for maintenance, increasing equipment maintenance costs and causing significant production time loss.

[0005] Therefore, there is an urgent need to design a nail feeding slide structure for a robotic nameplate welding system to solve the above problems. Summary of the Invention

[0006] This invention provides a nail feeding slide structure for a robot nameplate welding system, which solves the long-standing problem of nail jamming in nameplate welding robot systems and greatly reduces the failure rate of nameplate welding robot systems.

[0007] The technical solution adopted by this utility model to solve its technical problem is: A nail feeding slide structure for a nameplate welding robot system includes a vibrating plate, with the inlet of the nail feeding slide smoothly connected to the outlet end of the vibrating plate, and the outlet of the nail feeding slide connected to the nail picking point of the welding torch head of the nameplate welding robot. The nail feeding slide is used to convey welding nails vibrated in from the outlet end of the vibrating plate. The nail feeding track includes a basic track, which is U-shaped. The horizontal part of the basic track is fitted to the platform surface of the system. A basic pressure block and an L-shaped pressure block are stacked sequentially on the top of one of the vertical parts of the basic track. When the welding stud is embedded in the base slide and transmitted to the welding gun head of the nameplate welding robot under the vibration of the vibrating plate, the circumferential wall of the welding stud near the top contacts the side wall of the L-shaped pressure block, while the side wall of the base pressure block does not contact the welding stud. Furthermore, the welding stud includes a shank, on which a skirt is provided along the circumference, and a protruding arc-starting knot is provided at the top of the shank; The opening end of the base chute expands to both sides to form a T-shaped groove within the base chute; when the welding stud is being conveyed, the end of the stud with the arc-starting knot is embedded in the base chute, and the skirt of the welding stud matches the transverse part of the T-shaped groove. Furthermore, the transverse portion of the T-shaped groove is flush with the same side portion of the foundation block in the vertical direction; Furthermore, when the welding stud is embedded in the base track, there is a gap between the base pressure block and the welding stud rod. Furthermore, the L-shaped pressure block is elongated, and a stop bar is connected to the end where it connects to the nail-removing part of the welding gun head of the nameplate welding robot. The stop bar is perpendicular to the elongated shape.

[0008] By using the above technical solutions, compared with the prior art, this utility model has the following beneficial effects: 1. The nail feeding slide structure for the nameplate welding robot system provided by this utility model, compared with the conventionally designed robot nameplate welding system, expands the gap between the pressure block and the slide, ensuring the smooth flow of the welding nails when they are conveyed on the slide. 2. The nail feeding slide structure for the nameplate welding robot system provided by this utility model is simple in structure. It can be improved or remanufactured based on the traditional design without additional cost investment, and has extremely high economic benefits. Attached Figure Description

[0012] The present invention will now be described in further detail with reference to the accompanying drawings. In the description of this application, it should be understood that the terms "left side," "right side," "upper part," "lower part," etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. "First," "second," etc., do not indicate the importance of the components, and therefore should not be construed as a limitation of the present invention. The specific dimensions used in this embodiment are only for illustrating the technical solution and do not limit the scope of protection of the present invention.

[0013] Traditional robot welding nameplate systems often employ a rivet feeding slide structure, such as... Figure 1 As shown, there is a pressure block on each side of the slide. The gap between the pressure block and the slide is small. Once the two welding stud skirts overlap, it will cause a stud jamming problem, and the rear welding stud cannot be conveyed forward.

[0014] To address the aforementioned issues and considering the economic cost of redesigning, this application provides a nail feeding slide structure for a nameplate welding robot system. Its innovative design involves placing the base pressure block below the L-shaped pressure block, thus widening the gap between the pressure block and the slide. This design ensures that even if two adjacent nail skirts overlap, they will not get stuck, guaranteeing stable nail delivery. Simultaneously, it reduces the vibration power of the vibratory feeder storing the nails, extending its service life.

[0015] The entire design of this application is as follows: Figure 2-4 As shown, the inlet of the nail feeding slide smoothly connects to the outlet end of the vibratory feeder 1, and the outlet of the nail feeding slide connects to the nail picking point of the welding torch head of the nameplate welding robot. The nail feeding slide is used to convey the welding nails 4 vibrated in from the outlet end of the vibratory feeder; the nail transmission path ensures a smooth transition without jamming. The innovative design of this application is the nail feeding slide, which includes a basic slide, which is U-shaped. The lateral part of the basic slide is set to fit the platform surface of the system. Relying on the support of the platform, the shaking of the welding nails during transmission can be reduced, ensuring the stability of the overall structure of the slide.

[0016] A base pressure block 2 and an L-shaped pressure block 3 are sequentially stacked on top of one vertical section of the base slide. When the welding stud is embedded in the base slide and transmitted to the welding torch head of the nameplate welding robot under the vibration of the vibrating plate, the circumferential wall of the welding stud near the top contacts the side wall of the L-shaped pressure block, while the side wall of the base pressure block does not contact the welding stud. Obviously, the stacking of the base pressure block and the L-shaped pressure block constitutes a limiting mode, breaking the constraint of the traditional double-sided small gap pressure block. It only requires precise limiting in a single direction, which not only ensures the accuracy of the welding stud transmission direction, but also greatly reduces the contact area between the pressure block and the welding stud, solving the risk of stud jamming caused by dust accumulation in the gap and component wear in the traditional design.

[0017] Regarding the aforementioned innovative design features, the applicant must emphasize that the stud feeding slide structure provided in this application is adapted to the stud transportation conditions in this field. Specifically, the studs targeted by this application's slide structure include a rod portion with a skirt along the circumference and a protruding arc-starting knot at the top. The end without the arc-starting knot is the stud-grabbing position of the robotic welding torch. The robotic welding torch grabs the stud, aligns the arc-starting knot with the area to be welded, and initiates the operation to complete the nameplate welding process.

[0018] To perfectly realize the above design concept, further optimization is needed in the details. The opening of the basic chute expands inward to both sides, forming a T-shaped groove within the basic chute. During stud delivery, the end of the stud with the arc-starting knot is embedded in the basic chute, and the stud's skirt matches the lateral portion of the T-shaped groove. This precise matching and positioning of the stud and the basic chute, along with the lateral portion of the T-shaped groove providing stable support and restraint for the stud's skirt, prevents the stud from shifting or flipping during vibration transmission. Compared to traditional narrow-mouth chutes, the expanded opening facilitates smooth entry of the stud into the basic chute. Combined with the aforementioned matching of the skirt and the T-shaped groove, this guides the stud, preventing it from getting stuck in the chute during transmission and improving the smoothness and reliability of stud delivery.

[0019] Meanwhile, the transverse portion of the T-shaped groove is flush with the same side portion of the base block in the vertical direction. When the welding stud is embedded in the base slide, there is a gap between the base block and the welding stud rod, which further improves the welding stud feeding slide structure. The former flush design avoids the formation of a height difference on the same side in the vertical direction, ensuring that the welding stud remains on a stable trajectory during transmission within the base slide. The flush side of the base block also provides auxiliary guidance, reducing the risk of stud jamming. The latter gap design provides ample room for the welding stud rod to move; the reserved gap does not affect the limiting of the welding stud, while also preventing jamming caused by dust accumulation or component wear during long-term operation.

[0020] All of the above features work together to achieve a balance between precise positioning and flexible anti-jamming, which not only reduces the probability of nail jamming but also extends the maintenance cycle of the nail feeding slide.

[0021] Finally, regarding the L-shaped pressure block, it is elongated and has a stop bar connected to the end where it connects to the nail-picking point of the welding torch head of the nameplate welding robot. The stop bar is perpendicular to the elongated shape. The elongated design can continuously limit the nail's transmission path on one side. When the nail is transmitted to the nail-picking point, the stop bar accurately delivers the nail to the preset nail-picking position, facilitating the accurate and rapid grasping of the nail by the welding torch head of the nameplate welding robot, thus improving nail-picking efficiency and accuracy.

[0022] In summary, this application can improve the smooth flow of welding studs on the slide, prevent stud jamming accidents, help improve the stability of the nameplate welding robot system, and promote the development of nameplate welding robot system technology. It also has practical application value and can be widely used in the market. After use, it can effectively improve equipment stability and production efficiency, and achieve safe production and a safe working environment. Finally, by reducing economic losses caused by stud jamming failures, it can improve production efficiency and reduce enterprise losses.
