Description

Technical Field

[0001] This utility model relates to the technical field of automated warehousing and aging handling equipment, and more particularly to a ground rail handling system. Background Technology

[0002] Automated warehousing systems are typically used for storing products and raw materials; these are general warehousing systems. In addition, warehousing systems can be combined with specific functional devices to form functional warehousing systems. For example, combining a warehousing system with aging and testing devices can form an aging test warehousing system.

[0003] The main structure of the automated warehousing system is a storage box. Inside the storage box, there are aisles running along its length. Storage units are densely arranged along the sides of the aisles, each independently storing products. An aging detection device can be installed within each storage unit, enabling it to perform aging detection. A floor-rail transport system is installed within the aisles. This system retrieves products from the loading position and delivers them to pre-set storage units, and can also retrieve products from pre-set storage units and transport them to the unloading position. The floor-rail transport system includes floor rails, a translation drive mechanism, a lifting frame, a lifting platform, a lifting drive mechanism, and a robotic arm. The lifting frame slides on the floor rails, and the translation drive mechanism moves the lifting frame along the floor rails. The lifting platform is mounted on the lifting frame, and the lifting drive mechanism drives the lifting platform to move up and down on the lifting frame. The robotic arm is mounted on the lifting platform.

[0004] In some warehousing systems, drive belts are used to move lifting frames. After assembly, the slack of the drive belt is usually reduced. The drive belt is in a taut state for a long time, and it is prone to stretching and severe wear after long-term use. This is especially true for long passages, where stretching and wear are more likely to be aggravated, resulting in low movement accuracy over long periods of time. Utility Model Content

[0047] like Figure 1-3 The above describes a ground rail transport system, which includes a guide rail mechanism 1, a lifting frame 2, a first drive mechanism 3, a lifting platform 4, a second drive mechanism 5, and a robotic arm 6.

[0048] Specifically, the guide rail mechanism 1 includes a first guide rail 11 and a first rack 12. The first guide rail 11 extends along the X-axis, and the first rack 12 extends along the X-axis. The lifting frame 2 is slidably mounted on the first guide rail 11. The first drive mechanism 3 includes a first power element 31 and a first gear 32. The first power element 31 is located at the bottom of the lifting frame 2 and is connected to the first gear 32 to drive the first gear 32 to rotate. The first gear 32 meshes with the first rack 12. The lifting platform 4 is vertically mounted on the lifting frame 2. The second drive mechanism 5 is connected to the lifting platform 4 to drive the lifting platform 4 to move up and down. The robotic arm 6 is mounted on the lifting platform 4.

[0049] In this invention, a first rack 12 extending along the X-axis is provided on the guide rail mechanism 1, and a first drive mechanism 3 is provided at the bottom of the lifting frame 2. In the first drive mechanism 3, a first power element 31 is connected to the first rack 12 via a first gear 32, thereby driving the lifting frame 2 to move along the first guide rail 11. The meshing of the first gear 32 and the first rack 12, combined with lubricating grease, results in low load wear. In the long-distance guide rail mechanism 1, this design offers a long service life, resistance to deformation, stable movement accuracy over extended periods, and excellent stability.

[0050] In some embodiments of the lifting frame 2, such as Figure 2 , Figure 3As shown, the lifting frame 2 includes a frame body, a second guide rail 24, and a second rack 25. The second guide rail 24 is mounted on the frame body along the Z-axis, and the second rack 25 is mounted on the frame body along the Z-axis. The lifting platform 4 is vertically mounted on the second guide rail 24.

[0051] The second drive mechanism 5 includes a second power element 51 and a second gear 52. The second power element 51 is disposed on the lifting platform 4. The second power element 51 is connected to the second gear 52 to drive the second gear 52 to rotate. The second gear 52 meshes with the second rack 25.

[0052] In the lifting frame 2, the second power element 51 meshes with the second rack 25 through the second gear 52, thereby driving the lifting platform 4 to move up and down along the Z-axis. With the help of lubricating grease, it has low load wear, long service life, is not easy to deform, and has stable lifting accuracy over a long period of use, thus having good stability.

[0053] Specifically, the frame includes a base plate 21, two uprights 22, and a top plate 23. The two uprights 22 are respectively located at both ends of the base plate 21, and both ends of the top plate 23 are connected to the tops of the two uprights 22. A second guide rail 24 and a second rack 25 are respectively located on the uprights 22. Additionally, the first power element 31 is specifically located on the base plate 21.

[0054] For the column, the column 22 is preferably made of aluminum profile, such as an aluminum profile that is 80 mm wide and 200 mm long. In this way, the front, back and sides of the aluminum profile have mounting grooves that extend along the height direction, and the second guide rail 24 and the second rack 25 can be installed on the column 22 very conveniently.

[0055] Furthermore, there are four second guide rails 24, with two second guide rails 24 respectively located on both sides of the Y-axis of one column 22, and the other two second guide rails 24 respectively located on both sides of the Y-axis of the other column 22. The four guide rails effectively increase the stability of the lifting platform 4 during lifting.

[0056] In some embodiments of the lifting platform 4, the lifting platform 4 includes two vertical plates arranged side by side and a plurality of connecting plates disposed between the two vertical plates, wherein some of the connecting plates are disposed along the upper part of the two vertical plates and other connecting plates are disposed along the lower part of the two vertical plates. The robotic arm 6 is disposed on the two vertical plates.

[0057] In addition, for the purpose of installing the second drive mechanism 5, the lifting platform 4 also includes a drive mounting plate, which is located at the bottom of the lifting platform 4. Specifically, the drive mounting plate is set at the bottom of the connecting plate set along the lower part of the two vertical plates.

[0058] In some embodiments of the second drive mechanism 5, such as Figure 3 , Figure 4As shown, each of the two columns 22 is equipped with a second rack 25. The second drive mechanism 5 also includes a reducer 53, a transfer case 54, and two transmission rods 55. There are two second gears 52. The second power element 51 is connected to the reducer 53, the reducer 53 is connected to the transfer case 54, and the two sides of the transfer case 54 are connected to the two transmission rods 55. The ends of the two transmission rods 55 are respectively connected to two second gears 52, and the two second gears 52 mesh with the two racks respectively.

[0059] In this embodiment, the second power element 51 is reduced in speed by the reducer 53, outputs power to both sides through the transfer case 54, and transmits power to both sides through two transmission rods 55. Finally, it meshes with two second racks 25 through two second gears 52 respectively, thereby realizing synchronous driving of both sides of the lifting platform 4 and improving the balance and stability of the lifting platform 4.

[0060] The transfer case 54 includes a housing, an input shaft, an output shaft, and two bevel gears. The input and output shafts are vertically aligned and driven by the meshing of the two bevel gears. Both ends of the output shaft protrude from the housing, allowing power to be output to both sides. Two drive rods 55 are connected to the two ends of the output shaft via two couplings.

[0061] In some embodiments of the guide rail mechanism 1, such as Figure 3 As shown, the guide rail mechanism 1 also includes a third guide rail 13. There are two first guide rails 11 arranged side-by-side, and the third guide rail 13 is positioned above the two first guide rails 11. The top of the lifting frame 2 slides in conjunction with the third guide rail 13. In this embodiment, the two first guide rails 11 are arranged side-by-side and located below, while the third guide rail 13 is located above, forming a triangular arrangement, which effectively improves the stability of the guide.

[0062] In addition, guide wheel mechanisms 26 are respectively provided on both sides of the top of the lifting frame 2, and the guide wheel mechanisms 26 are in rolling cooperation with the third guide rail 13. The guide wheel mechanisms 26 guide the lifting frame 2 to move along the X-axis.

[0063] In some embodiments of the guide wheel mechanism 26, the guide wheel mechanism 26 includes three guide wheels, three mounting blocks, three adjusting blocks, and three adjusting screws.

[0064] Two mounting blocks are located on either side of the third guide rail 13, and the other mounting block is located on top of the lifting frame 2 and below the third guide rail 13. Each mounting block has an elongated hole for assembly, the length of which is perpendicular to the third guide rail 13. Three guide wheels are respectively mounted on their corresponding mounting blocks; two guide wheels roll into contact with the sides of the third guide rail 13, and the other guide wheel rolls into contact with the bottom of the third guide rail 13. Three adjusting blocks are respectively located on the side of the three mounting blocks furthest from the third guide rail 13. Three adjusting screws are respectively mounted on the three adjusting blocks, with their ends abutting against the mounting blocks, used to adjust the pressure of the corresponding guide wheels on the third guide rail 13 during installation.

[0065] During assembly, the guide wheel is mounted on the corresponding mounting block and initially tightened using screws located in the elongated holes. At this point, pressure can be applied to the mounting block by adjusting the screws, thereby adjusting the pressure of the guide wheel on the third guide rail 13. After adjusting to the appropriate pressure, the screws in the elongated holes are tightened to achieve the assembly adjustment.

[0066] Additionally, on lifting platform 4, such as Figure 1 As shown, there are two robotic arms 6, arranged side by side. The two robotic arms 6 can perform pick-up and put-down operations in steps and complete the process in one round trip, thereby improving work efficiency.

[0067] Specifically, the first power element 31 and the second power element 51 mentioned above can be an electric motor or a pneumatic motor capable of outputting rotary motion.

[0068] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
