Description

Technical Field

[0001] This utility model relates to the field of industrial robot ground rail technology, and in particular to a ground rail system. Background Technology

[0002] In the field of industrial automation, six-degree-of-freedom (DOF) industrial robots have been widely used in welding, handling, painting, sorting, and assembly operations due to their high flexibility. However, traditional six-axis robots are typically mounted on a fixed base, and their working range is strictly limited by their arm span. When facing long-distance, large-area applications such as automotive body welding, large warehouse logistics sorting, and handling long objects, a single fixed robot cannot meet the full-coverage operation requirements. To solve this problem, the industry commonly uses external moving axes for robots, the so-called "seventh axis" or "ground rail system," which allows the robot to move on a straight track, greatly expanding its single-machine working range.

[0003] The prior art, disclosed in publication number CN219235285U, discloses a ground-rail robot system for a processing production line, which "comprising a ground-rail body, a sliding slide, a lubrication system, a cable chain mechanism, a transmission system, a six-axis robot, and a gripping mechanism; the ground-rail body is connected to the sliding slide via a guide rail slider mechanism; the lubrication system is fixed to the sliding slide; the cable chain mechanism is connected at both ends to the ground-rail body and the sliding slide respectively; the transmission system is fixed to the sliding slide and achieves mutual movement between the sliding slide and the ground-rail body via a gear and rack mechanism; the six-axis robot is fixed to the sliding slide; and the gripping mechanism is fixed to the six-axis robot." The aforementioned robot tracks employ an integrated or customized design, with their length and load capacity fixed upon completion of manufacturing. Once the production line layout requires adjustments due to product iterations, the existing tracks often cannot be easily modularized or modified, necessitating complete replacement. This results in high modification costs and lengthy cycles, failing to adapt to the flexible and digitalized production trends of modern manufacturing. Furthermore, in terms of safety, many track systems are only equipped with basic limit switches, lacking multiple, redundant safety mechanisms, posing safety hazards in high-speed, heavy-load applications. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a ground track system that more precisely solves the issues of poor scalability and flexibility, and poor safety protection of existing robot ground tracks.

[0005] This utility model is achieved through the following technical solution: This utility model proposes a ground rail system, including a fixed base made of high-strength steel. The fixed base has mounting brackets symmetrically installed on its side walls. A connecting component is provided between the fixed bases to connect them. A protective component is provided on the inner wall of the fixed base to limit and protect the movement of the robot.

[0006] Furthermore, a protective plate is bolted to the top of the fixed base, and a drag chain support structure is installed at the center of the top of the fixed base.

The two sets of linear guides are symmetrically mounted on the top of the fixed base by bolts. The rack is mounted on the side wall of the guide rail mounting plate above the fixed base by bolts.

[0008] Furthermore, a slide base is provided above the linear guide rail, and multiple sets of sliders are symmetrically installed on the bottom of the slide base by bolts, while a robot is installed on the top of the slide base by bolts.

[0009] Furthermore, a servo motor is bolted to the top of the slide base, a planetary reducer is mounted at the output end of the servo motor, and a helical gear is mounted at the output end of the planetary reducer.

[0010] Furthermore, the helical gear meshes with the rack for transmission, the slider slides with the linear guide rail, and lubrication channels are provided in the bottom of the slide base and the fixed base.

[0011] Furthermore, the protective assembly includes an electric lubrication pump, a cable chain, and a fixing bar. The electric lubrication pump is bolted to the top of the slide base. An oil distributor is installed at the output end of the electric lubrication pump, and a nylon hose is installed at the output end of the oil distributor. The cable chain is bolted to the side wall of the slide base, and the fixing bar is bolted to the side wall of the guide rail mounting plate above the fixed base.

[0012] Furthermore, the cable chain is located within the cable chain support structure, two sets of limit switches are installed on the side wall of the fixing bar, and limit blocks are installed on the guide rail mounting plate above the fixing base.

[0013] The beneficial effects of this utility model are: This utility model proposes a ground rail system, which, by incorporating connecting and protective components, allows for quick connection and fixation between fixed bases.

[0016] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0017] Please refer to Figures 1-6This utility model proposes a ground rail system, including a fixed base 1 made of high-strength steel, which can provide stable support for the movement of robot 12 and reduce the risk of ground rail vibration when robot 12 moves at high speed. The fixed base 1 has mounting brackets 2 symmetrically installed on its side walls for mounting and fixing the fixed base 1. The fixed base 1 is provided with connecting components for connecting the fixed base 1. The inner wall of the fixed base 1 is provided with protective components for limiting the movement of robot 12. The top of the fixed base 1 is bolted with a protective plate 3, which can intercept dust. The protective plate 3 is detachable for easy maintenance or replacement by users. The center of the top of the fixed base 1 is equipped with a drag chain support structure 4 for limiting the drag chain 19.

[0018] The connecting assembly includes two sets of linear guides 5, a rack 6, and a connecting frame 7. The two sets of linear guides 5 are symmetrically mounted on the top of the fixed base 1 with bolts to ensure stable sliding of the robot 12 slide base 10. The rack 6 is bolted to the side wall of the guide rail mounting plate above the fixed base 1 to limit the movement of the helical gear 15. The connecting frame 7 is welded to the outer wall of the fixed base 1 to connect and fix the fixed bases 1. Connecting bolts 8 are installed between the connecting frames 7, and fixing bolts 9 are installed inside the connecting frames 7. The slide base 10 is set above the linear guides 5 for mounting the robot 12. Multiple sets of sliders 11 are symmetrically mounted on the bottom of the slide base 10 with bolts. The robot 12 is bolted to the top of the slide base 10 to perform welding or handling operations. A servo motor 13 is bolted to the top of the slide base 10 to drive the helical gear 15. Gear 15 rotates, servo motor 13 is equipped with an absolute encoder, and planetary reducer 14 is installed at the output end of servo motor 13 to ensure that servo motor 13 outputs high torque. Helical gear 15 is installed at the output end of planetary reducer 14. Helical gear 15 meshes with rack 6 for transmission. Slider 11 is slidably set with linear guide rail 5. Lubrication channels are provided at the bottom of slide base 10 and inside fixed base 1. With the setting of fixing bolt 9, connecting bolt 8 and connecting bracket 7, fixed base 1 can be quickly connected and fixed together. Modular splicing design reduces installation and maintenance costs and improves the expandability of ground rail. Using servo motor 13 to drive helical gear 15 to rotate, under the limit of rack 6, slider 11 and linear guide rail 5, helical gear 15 moves along rack 6. The movement of helical gear 15 drives slide base 10 to move, and then drives robot 12 to move. With the cooperation of encoder, robot 12 can move accurately over long distances.

[0019] The protective assembly includes an electric lubrication pump 16, a cable chain 19, and a fixing bar 20. The electric lubrication pump 16 is bolted to the top of the slide base 10. An oil distributor 17 is installed at the output end of the electric lubrication pump 16 for distributing oil. A nylon hose 18 is installed at the output end of the oil distributor 17 and is connected to a lubrication point. The cable chain 19 is bolted to the side wall of the slide base 10. Power lines and signal lines are arranged in sections inside the cable chain 19. The fixing bar 20 is bolted to the side wall of the guide rail mounting plate above the fixed base 1. The cable chain 19 is located within the cable chain support structure 4. Two sets of guide rails are installed on the side wall of the fixing bar 20. Two sets of limit switches 21 are used to send deceleration and stop commands respectively. Limit blocks 22 are installed on the guide rail mounting plate above the fixed base 1 to mechanically limit the slide base 10. The electric lubrication pump 16 has a built-in oil level sensor. With the cooperation of the oil distributor 17 and the nylon hose 18, the lubricating oil is distributed to each lubrication point in proportion, which significantly reduces the wear of transmission components and extends the maintenance cycle. With the setting of two sets of limit switches and limit blocks 22, the movement of the slide base 10 can be limited and protected, reducing the risk of robot 12 derailment. It can also ensure that robot 12 stops stably and smoothly, reducing the wear and safety hazards caused by forced stopping.

[0020] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
