Description

Technical Field

[0001] This utility model relates to the technical field of loading and unloading devices, specifically to an automatic loading and unloading device with a fixed length function. Background Technology

[0002] As a core component of artwork mounting, the frame strip utilizes an L-shaped cross-section design to achieve a tight fit and aesthetic adaptability. Its materials encompass wood, aluminum alloy, and composite materials, with specific craftsmanship tailored to different art forms such as traditional Chinese painting and oil painting. Current technology features frame strips with seamless assembly, employing a slot structure for convenient disassembly, assembly, and replacement of parts, while the inlaid edge design combines protection with a visually smooth transition. The frame strip demonstrates decorative adaptability in both museum displays and modern home settings, balancing artistic presentation with practical needs through innovative material textures and structures. In the design of frame strip length-fixing equipment, the stability requirements for loading and unloading equipment are becoming increasingly stringent in order to improve output and efficiency. However, frame strips vary in width, and traditional sponge suction cup loading and unloading methods cannot meet the stability requirements, easily causing frame strips to fall off, which in turn affects the adsorption of the material below, impacting production and efficiency. In push-plate loading and unloading modes, the excessively long push plate stroke causes friction between upper and lower frame strips, leading to surface scratches and other abnormalities, affecting product quality. The unloading section also suffers from material falling off and scratches, creating stacking gaps, resulting in uneven stacking or even complete scattering, preventing the downstream automated equipment from properly handling the material.

[0003] To solve the above problems, there is an urgent need to invent an automatic loading and unloading device with a fixed length function. Utility Model Content

[0019] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0020] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0021] In the description of this utility model, it should be understood that the use of terms such as "first" and "second" to define the components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this utility model.

[0022] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] An automatic loading and unloading device with a fixed length function includes a loading mechanism 1, a material dividing and cutting mechanism 2, and an unloading mechanism 3; the loading mechanism 1 is configured to transport frame strip material to the material dividing and cutting mechanism 2, and the material dividing and cutting mechanism 2 is configured to divide the frame strip material into fixed lengths and transport the resulting finished frame strips to the unloading mechanism 3. in, The feeding mechanism 1 includes a pallet positioning device 11 and a contouring drive mechanism 12. The pallet positioning device 11 is disposed at the feeding end of the feeding mechanism 1 and is configured to support and position the frame strip material. The contouring drive mechanism 12 is configured to push the frame strip material in the pallet positioning device 11 from one side of the pallet positioning device 11 to the other side of the pallet positioning device 11 for positioning. The material dividing and cutting mechanism 2 includes a material dividing and cutting platform 21, an equal division cutting device 22, and a precision length fixing mechanism 23. The equal division cutting mechanism 22 is configured to cut the frame strip material into equal-divided frame strip semi-finished products, and the precision length fixing mechanism 23 is configured to precisely lengthen the frame strip semi-finished products into finished frame strip products.

[0024] Specifically, the core advantage of this automatic loading and unloading device lies in its successful achievement of high-efficiency, high-precision, and high-stability processing of frame strip materials through automated integration and precision positioning technology. It not only significantly reduces reliance on manpower and production costs but also ensures consistent product quality, making it highly suitable for the needs of modern, large-scale industrial production.

[0025] in, 1. High degree of automation, significantly improved efficiency Integrated process: The feeding, sorting, cutting, length setting and unloading are integrated into a continuous automated process, eliminating material stagnation and manual handling time between processes, and greatly improving overall production efficiency.

[0026] Contouring-driven feeding: The contouring-driven feeding mechanism can stably and continuously push the material to the designated position, ensuring the smoothness and rhythm of the feeding process and providing a guarantee for the stable operation of subsequent processes.

[0027] 2. Precise positioning and high processing quality Dual positioning ensures accuracy: the feeding end has a "pallet positioning device" for initial positioning, and the material cutting stage has a "precision length-setting mechanism" for precise positioning. This dual positioning mechanism effectively guarantees the positional accuracy of the material during processing.

[0028] Precision Length Measurement: A dedicated "precision length measurement mechanism" ensures the accuracy of the final frame strip's length dimensions, meeting high processing standards and resulting in good product consistency.

[0029] 3. Integrated functions, saving space and cost Mechanism integration: The "equal division cutting" and "precision length setting" functions are integrated into the "material cutting mechanism", which makes the equipment structure compact and reduces the floor space.

[0030] Multi-functional: This device simultaneously completes two key processes: division (equal cutting) and precision machining (precision sizing), reducing the need for additional independent equipment and lowering equipment purchase and maintenance costs.

[0031] 4. Stable and reliable operation Contouring drive: "Contouring drive mechanism" usually means that the pushing device matches the shape of the material, which can provide uniform driving force, avoid damage or jamming to the material during the pushing process, and make the operation more stable.

[0032] Clear division of labor in the process: The feeding, sorting and cutting, and unloading mechanisms have clear division of labor and each performs its own duties, which makes the logic of the whole system clear, reduces the occurrence of failure points, and improves the reliability and durability of the equipment.

[0033] In one specific embodiment, the pallet positioning device 11 is tilted with an inclination angle A of 5°-15°, and the pallet positioning device 11 is tilted downward toward the side away from the material cutting platform 21.

[0034] For example, preferably, the tilt angle A is approximately 10°. It is understood that while 10° is ideal, some error may occur during the setting process; as long as the error does not exceed ±2°, it is acceptable. Specifically, gravity self-positioning ensures smooth and stable feeding; automatic alignment with the reference surface is achieved. The tilted pallet allows the frame material to naturally slide towards and press against the positioning reference surface (such as a baffle or guardrail) on the lower side of the pallet under its own weight. This realizes a passive and continuous self-correction process, ensuring that each piece of material has a consistent and accurate initial position when entering the pushing station, laying a solid foundation for subsequent contour pushing and precision cutting. Eliminating gaps and jamming: Compared to horizontally placed pallets where gaps may cause material skewing, the tilted design effectively eliminates the gap between the material and the positioning surface, preventing material displacement or jamming during transport, greatly improving the reliability and stability of feeding.

[0035] In one specific embodiment, the downward tilting end of the pallet positioning device 11 is provided with a lifting mechanism 111, and the lifting mechanism 111 is configured to prevent the frame material from collapsing.

[0036] In one specific embodiment, the other side of the pallet positioning device 11 is set as the positioning side, and the positioning side is provided with a frame strip clamping mechanism 112. The frame strip clamping mechanism 112 is configured to clamp the positioned frame strip material and transfer it to the material distribution and cutting platform 21. For example, the frame strip clamping mechanism can be a robotic arm or a robotic hand.

[0037] In one specific embodiment, the pushing distance of the contour driving mechanism 12 is 100mm-200mm.

[0038] Specifically, optimizing the cycle time for high-efficiency production: Short stroke, fast pace: The short push distance of 100-200mm means that the actuator's action time is very short. This allows the feeding process to proceed at a very high frequency, perfectly matching the high-speed cycle of the subsequent material sorting and cutting mechanism, thus significantly improving the overall production line efficiency. It avoids the waiting time caused by long-distance pushes, achieving a "seamless connection" of production rhythm. Improving the stability and accuracy of push: Enhanced rigidity, reduced error: The short-stroke mechanical structure inherently has better rigidity and stability. Compared to long-stroke pushes, it produces less vibration, deformation, and accumulated error during movement. This ensures that each push accurately moves the material a fixed, preset distance, providing a reliable guarantee for subsequent precision sizing and cutting. More precise control: Whether using cylinders, electric actuators, or servo motors, controlling a short-stroke movement makes it easier to achieve precise start-stop and position control than controlling a long stroke. Compact structure, saving space: Reducing mechanism size: The push distance directly determines the size of the contour drive mechanism and the space required for its installation. The 100-200mm stroke allows the entire pushing mechanism to be made very small and compact, which helps to reduce the footprint of the entire feeding mechanism, making the equipment layout more reasonable and meeting the high requirements of modern factories for space utilization.

[0039] In one specific embodiment, the equal-division cutting device 22 includes two material-dividing cutting electric saws, which are respectively arranged on opposite sides of the material-dividing cutting platform 21 to form a double-end saw structure. For example, the material-dividing cutting electric saws are mounted on a gantry frame structure and can move along the gantry structure in the XYZ directions to cut the frame strips.

[0040] In one specific embodiment, the feeding end of the precision sizing mechanism 23 is provided with a lifting and translation mechanism, which is configured to feed the frame strip semi-finished product into the precision sizing mechanism 23 for precision sizing into the finished frame strip.

[0041] In one specific embodiment, the feeding mechanism 3 includes a frame strip assembly device 31, which is configured to reassemble the finished frame strips. In one specific embodiment, the unloading mechanism 3 further includes a gripping device 32 configured to grip the reassembled frame strip finished products off the unloading mechanism 3; for example, the gripping device may be a robotic arm or a robotic hand.

[0042] In one specific embodiment, the feeding mechanism 3 further includes a feeding tray.

[0043] The above description is only an exemplary embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
