Description

Technical Field

[0001] This utility model relates to the field of logistics transfer technology in the assembly manufacturing industry, specifically a logistics island structure for multi-category assembly manufacturing industries. Background Technology

[0002] In the assembly manufacturing industry, especially in multi-category, small-batch production models, material logistics is a key factor affecting production efficiency. The ability to achieve timely material supply, accurate sorting, and rapid changeover directly impacts the continuity of assembly processes and the work efficiency of operators. Optimizing logistics in this area has always been an important research direction within the industry.

[0003] In the existing technology, the transfer of materials required for assembly mostly adopts the traditional mode, that is, materials are centrally stored in warehouses, and materials are moved from the warehouses to each assembly station by manpower or simple equipment according to production needs. Usually, only simple shelves or stacking areas are set up next to the workstations for temporary storage of materials. There is a lack of special handling mechanisms for different types of materials, and material distribution mostly relies on manual judgment and back-and-forth handling.

[0004] Existing technologies can handle the material handling required for assembly, but there are still some shortcomings in actual operation. The existing workstation space is small and crowded due to the lack of systematic planning, and the random stacking of materials leads to disorder. Operators have to spend a lot of time searching for the required materials, resulting in a significant reduction in space utilization. Due to the lack of specialized handling mechanisms for different types of materials, material delivery relies heavily on manual judgment and back-and-forth handling, making it difficult to achieve accurate, efficient, and timely delivery. Especially in multi-variety, small-batch assembly manufacturing scenarios, the need for rapid material changeover cannot be met, directly leading to low delivery timeliness, which in turn restricts the overall efficiency of production assembly and fails to meet the requirements of lean manufacturing.

[0027] Please see Figure 8 As shown, the sorting material bin 9 includes a seeding wall 901, which is located on the left side of the work area 5. Inside the seeding wall 901, there are multiple evenly distributed sorting material boxes 902, and each sorting material box 902 is equipped with an indicator light 903 on its outer periphery.

[0028] Specifically, the seeding wall 901 is located on the left side of the work area 5 and is used to place multiple evenly distributed sorting material boxes 902 to provide space for storing sorted materials. The sorting material boxes 902 are placed inside the seeding wall 901 and are used to classify and hold different sorted materials, making it convenient for operators to directly take them during assembly. Indicator lights 903 are installed on the outer periphery of multiple sorting material boxes 902 to indicate the corresponding sorting material box 902 and guide the operator to accurately send the materials into the corresponding sorting material box 902.

[0029] Please see Figures 10-11As shown, the large material storage 10 includes a fixed table 1001, which is located on the right side of the work area 5. A double-layer shelf 1002 is rotatably connected to the top of the fixed table 1001. A storage layer 1003 is provided on the upper left side of the double-layer shelf 1002, and a storage layer 2 1004 is provided on the lower right side of the double-layer shelf 1002.

[0030] Specifically, the fixed table 1001 is located on the right side of the work area 5 and is used to support the double-layer shelf 1002 on top, providing a stable installation platform for the operation of large materials. The double-layer shelf 1002 can be rotated to switch storage layers. Storage layer one 1003 is located on the upper left side of the double-layer shelf 1002 and is used to store the currently used large materials for the operator to access. Storage layer two 1004 is located on the lower right side of the double-layer shelf 1002 as a spare storage space. When the materials in storage layer one 1003 are used up, the shelf can be rotated to align with the operator for access. Motor two 1005 is installed at the bottom of the fixed table 1001 and its output end is fixedly connected to the bottom of the double-layer shelf 1002, providing power for the rotation of the double-layer shelf 1002 and realizing the rapid switching between storage layer one 1003 and storage layer two 1004.

[0031] The working principle of this utility model is as follows: In the overall logistics operation, the main warehouse 1 delivers the materials needed for the next day's production line to the branch warehouse 2 at night, thereby significantly shortening the delivery distance. During the daytime production line operation, the AGV scheduling module 304 coordinates the hidden robot 301, intelligent forklift 302, and CTU robot 303 to deliver the materials from the main warehouse 1 to the branch warehouse 2 at night. From the branch warehouse 2, the materials are then accurately and automatically delivered to the line-side warehouse 4, which is arranged in a U-shape around the work area 5. This is combined with the automatic replenishment of the standby material warehouse 7 by gravity, the quick retrieval of designated materials by the designated material warehouse 8, the accurate sorting of the sorting material warehouse 9 guided by the indicator light 903, and the efficient turnover of the large-item material warehouse 10 through the rotating shelf. Together, these mechanisms realize the unmanned automatic transfer of materials from warehousing, delivery, process transfer to production inspection, effectively solving the problems of finding materials, untimely delivery, and production scheduling in multi-variety, small-batch discrete manufacturing industries, and improving overall production efficiency.

[0032] When you need to access the stocked materials, simply take the stocked materials from the stocked material box 703. After you have taken all the stocked materials from one stocked material box 703, simply remove the empty stocked material box 703. The remaining stocked material boxes 703 will fill the gaps by their own weight, so there is no need to move them frequently. When a specific material needs to be retrieved, the motor 810 is started to drive the rotating frame 801 to rotate, causing the material to be retrieved to move in front of the electric telescopic rod 809. At this time, the electric telescopic rod 809 is started, pushing the sliding block 803 to slide on the sliding rod 802, thereby moving the designated material box 804 and pushing it out so that the operator can retrieve the designated material. After retrieval, the electric telescopic rod 809 is returned to its original position, which releases the tension of the spring 805, resets the sliding block 803, and resets the designated material box 804 for the next use. This allows for quick location of the required material and avoids material search time. When materials need to be sorted, logistics personnel deliver the entire set of sorted materials to the seeding wall 901 at once according to the order. The operator checks the indicator light 903 on the sorting material box 902 and sends the materials into the corresponding sorting material box 902 according to the instructions. This allows the operator to directly take the sorted materials in the sorting material box 902 during assembly, thereby improving efficiency. When retrieving large materials, after the large materials in storage layer 1003 are taken out and used, motor 2 1005 will be automatically started, thereby driving the double-layer shelf 1002 to rotate, so that storage layer 2 1004 is aligned with the operator. Storage layer 1003 can be replenished with large materials, and storage layer 2 1004 can be directly retrieved. This cycle is repeated to avoid production line stoppages caused by waiting for the delivery of large materials.

[0033] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
