Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and in particular to a heavy-duty parallel robot for logistics warehousing. Background Technology

[0002] Statistics show that domestic enterprises spend only 5% of their time on processing and manufacturing during the entire product production process, while 95% of their time is spent on storage, loading and unloading, waiting for processing, and transportation. From a product cost analysis perspective, in the United States, direct labor costs account for less than 10% of production costs, and this proportion is continuously decreasing, while storage and transportation costs account for 40% of production costs. In my country's manufacturing industry, the automation level of unit process equipment is very high, making it difficult to further improve efficiency. Meanwhile, relatively backward production logistics has become a bottleneck restricting the improvement of production efficiency, with significant room for improvement. Therefore, in recent years, production logistics automation has become an important means for manufacturing enterprises to improve production efficiency and reduce production costs. In warehousing, sorting and handling operations account for approximately 90% of costs, with human labor directly involved in sorting accounting for 50%, and sorting time accounting for as much as 30% to 40% of the total operating time in the distribution center. Picking has become the starting point for the intelligent transformation of logistics warehousing.

[0003] Currently, most of the various operational processes in logistics warehousing, such as picking, packaging, loading and unloading, are carried out manually, which results in high labor intensity, low efficiency, and high labor costs. Utility Model Content

[0023] This invention proposes a heavy-duty parallel robot for logistics warehousing.

[0024] like Figures 1 to 5 As shown, in one embodiment of this utility model, the heavy-duty parallel robot for logistics warehousing includes a frame 101, a base 102, a first reduction motor 103, an active arm 104, a driven arm 105, a moving platform 106, and a sorting robot (not shown). The base 102 is disposed on the top of the frame 101. Three first reduction motors 103 are provided, and the first reduction motors 103 are symmetrically arranged in a triangular pattern on the lower end wall of the base 102. The upper ends of the active arms 14 are fixedly connected to the output shafts of the first reduction motors 103. The upper ends of the driven arms 105 are rotatably connected to the lower ends of the active arms 104, and can rotate left and right and up and down. The lower ends of the driven arms 105 are rotatably connected to the moving platform 106, and can rotate up and down and left and right. The sorting robot is disposed at the lower end of the moving platform 106.

[0025] Specifically, it also includes a second geared motor 107, which is located at the upper end of the moving platform 106. The sorting robot is connected to the output shaft of the second geared motor 107. The second geared motor enables the sorting robot to rotate, which can adapt to different application needs and has wide adaptability.

[0026] Specifically, it also includes a mounting base 108. The first geared motor 103 is a dual-output shaft motor. The mounting base 108 is respectively set on the output shafts on both sides of the first geared motor 103. The upper end of the active arm 105 is detachably and fixedly connected to the mounting base 108.

[0027] Specifically, it also includes fastening screws (not shown). The outer side wall of the mounting base 108 is recessed with multiple threaded holes 1081 along the circumferential direction. The two side walls of the upper end of the active arm 104 are respectively recessed with a U-shaped groove 1041. The output shaft of the first geared motor 103 is detachably inserted through the U-shaped groove 1041. The two side walls of the upper end of the active arm 104 are respectively recessed with multiple screw holes 1042 along the circumferential direction. The fastening screws are respectively inserted through the screw holes 1042 and screwed into the threaded holes 1081, making the installation and disassembly between the active arm and the output shaft of the first geared motor more convenient and quick. Moreover, the relative position between the active arm and the mounting base can be flexibly adjusted according to the needs of different applications, making it highly adaptable.

[0028] Specifically, the driven boom 105 includes a screw 1051 and a connecting rod 1052. The screw 1051 is arranged in parallel, and the connecting rod 1052 is arranged in parallel at the upper and lower ends of the screw 1051. The screw 1051 and the connecting rod 1052 together form a parallelogram connecting rod structure. The two ends of the screw 1052 are respectively rotatably connected to the connecting rod 1052 in the left and right directions. The two ends of the connecting rod 1052 are respectively rotatably connected to the lower end of the drive boom 104 and the moving platform 106 in the up and down directions through a bearing. The double screw structure has a higher load-bearing capacity, and the parallelogram connecting rod structure is stable and reliable in operation.

[0029] Specifically, it also includes a U-shaped bracket 1053 and a nut 1054. The U-shaped bracket 1053 is respectively disposed at both ends of the screw 1051. A through hole 1055 is recessed at the bottom of the U-shaped bracket 1053. Both ends of the screw 1051 are respectively disposed through the through hole 1055. The nut 1054 is respectively screwed onto both ends of the screw 1051, and the nut 1054 is respectively disposed at the upper end and the lower end of the through hole 1055. The upper end of the U-shaped bracket 1053 is rotatably connected to the connecting rod 1052 through a short shaft, so that the relative position between the screw and the connecting rod can be easily adjusted.

[0030] Specifically, the active arm 104, the driven arm 105, and the moving platform 106 are all made of carbon fiber. Carbon fiber has only one-third the density of steel and half that of aluminum alloy, yet it provides a higher specific strength (strength-to-weight ratio). Carbon fiber components can reduce weight by more than 60%, directly reducing inertial torque and improving the dynamic response speed and motion accuracy of the parallel robot. Simultaneously, lightweighting can reduce energy consumption by approximately 25%-30%. Carbon fiber composite materials also exhibit excellent fatigue resistance, lasting up to 10... 6 Maintaining a strength decay of less than 5% under repeated cyclic loads can extend the service life of parallel robots.

[0031] Specifically, the working principle and process of this utility model are as follows:

[0032] The base is mounted on top of the frame. Three first geared motors are arranged in a triangular symmetrical pattern on the lower wall of the base. The upper ends of the active arms are fixedly connected to the output shafts of the first geared motors. The upper ends of the driven arms are rotatably connected to the lower ends of the active arms, and the lower ends of the driven arms are rotatably connected to the moving platform, and the sorting robot is located at the lower end of the moving platform. The first geared motors enable precise and rapid translation of the moving platform, allowing the sorting robot to perform high-speed material grabbing and placement in packaging boxes. This significantly improves the intelligence of various operations in logistics warehousing, greatly enhancing efficiency and accuracy while reducing the need for manual labor, lowering labor intensity and labor costs, and demonstrating strong practicality.
