Description

Technical Field

[0001] This utility model relates to the field of industrial robot technology, and more specifically, to explosion-proof robots. Background Technology

[0002] Currently, spraying robots, which are commonly used in the market, are core equipment in the field of industrial automation. With their high precision, high efficiency and strong environmental adaptability, they have deeply penetrated into many industrial fields, especially in the automotive manufacturing, aerospace and electronics manufacturing industries, where they have shown irreplaceable value. In frigid environments, the lubrication systems of existing robots are prone to freezing, leading to decreased motion performance or even failure. In addition, existing robots cannot meet the comprehensive requirements of long-term stable operation in dust explosion-proof environments and low-temperature adaptability.

[0003] Therefore, an explosion-proof robot is proposed to address the above issues. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides an explosion-proof robot to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof robot, including a limiting seat and a six-axis robot. The six-axis robot includes a first connecting arm and a second connecting arm. Limiting seats are fixedly welded to the outer sides of both the first and second connecting arms. Connecting seats are rotatably connected to both limiting seats. Fixing rings are inserted into both connecting seats. A protective telescopic cover is fixedly connected between the two fixing rings. Multiple heating wires are fixedly connected at equal intervals to the outer wall of the protective telescopic cover. Multiple locking blocks are fixedly connected at equal intervals to the outer walls of both fixing rings. Multiple locking blocks are opened at equal intervals to the outer walls of both connecting seats. The device features a locking mechanism between the connecting seat and the fixed ring. During use, the locking mechanism between the locking block on the outer wall of the fixed ring and the locking groove on the outer wall of the connecting seat secures the two fixed rings and the protective telescopic cover between them. The protective telescopic cover protects the rotating joints of the six-axis robot from dust. Lubricating oil is filled inside the protective telescopic cover to lubricate the rotating joints of the six-axis robot. Heat is also generated by a heating wire to heat the lubricating oil, preventing it from freezing in low-temperature environments and affecting the rotation of the connecting joints.

[0006] Preferably, the locking assembly includes a fixed base, a locking groove, a locking seat, a locking rod, a connecting piece, a locking protrusion, and a locking spring. Multiple locking seats are fixedly arranged at equal intervals on the outer wall of the connecting base. The locking rod movably passes through the surface of the locking seat. A connecting piece is fixedly arranged at one end of the locking rod, and a locking protrusion is fixedly arranged on the connecting piece. A locking spring is sleeved and connected to the outer wall of the locking rod. Multiple fixed bases are fixedly arranged on the outer wall of the fixed ring. A locking groove is formed on the surface of the fixed base to engage with the locking protrusion. When the fixed ring connected to the connecting base is rotated, the locking protrusion slides into the locking groove on the surface of the fixed base. Simultaneously, the locking spring compresses the connecting piece, causing the locking protrusion to be tightly engaged in the locking groove. The engagement between the locking protrusion and the locking groove further improves the stability of the fixed connection at both ends of the protective telescopic cover.

[0007] Preferably, a stop is fixedly connected to one end of the locking rod, and the stop is located at the end of the locking rod away from the connecting piece. By setting the stop, the locking rod can be limited to prevent it from disengaging from the locking seat.

[0008] Preferably, the locking spring is located between the locking seat and the connecting piece, and both ends of the locking spring are fixedly connected to the locking seat and the connecting piece, respectively.

[0009] Preferably, a first rubber gasket is fixedly installed in each of the two connecting seats, and a second rubber gasket is fixedly connected to one end of each of the two fixing rings that are inserted into the connecting seats. By setting the fixing rings and the second rubber gaskets, the sealing performance of the connection between the two ends of the protective telescopic cover and the two connecting seats can be improved, and the lubricating oil leakage can be avoided after the lubricating oil is poured into the protective telescopic cover.

[0010] Preferably, a vision inspection camera is fixedly connected to the six-axis robot by bolts. The vision inspection camera has an internal light and is used to detect the cleaning effect and provide feedback to control the robot to perform re-spraying or re-sweeping.

[0011] Preferably, the six-axis robot is fixedly connected to a high-pressure nozzle at the end via a tapered tube joint and a sealant, for spraying high-pressure de-icing agent and hot air.

[0012] The technical effects and advantages of this utility model are as follows: Compared with existing technologies, this explosion-proof robot uses the locking block on the outer wall of the fixed ring and the locking groove on the outer wall of the connecting seat to fix two fixed rings and a protective telescopic cover set between the two fixed rings. The protective telescopic cover protects the six-axis robot's connecting rotation nodes from dust. At the same time, the protective telescopic cover is filled with lubricating oil to lubricate the six-axis robot's connecting rotation nodes. Heat is generated by heating wires to heat the lubricating oil, preventing the lubricating oil from freezing in low-temperature environments and affecting the rotation operation of each connecting rotation node.

[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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0020] As attached Figures 1 to 5The explosion-proof robot shown includes a limiting seat 1 and a six-axis robot 17. The six-axis robot 17 includes a first connecting arm 171 and a second connecting arm 172. The limiting seats 1 are fixedly welded to the outer sides of the first connecting arm 171 and the second connecting arm 172. Connecting seats 2 are rotatably connected to the two limiting seats 1. Fixing rings 4 are inserted into the two connecting seats 2. A protective telescopic cover 6 is fixedly connected between the two fixing rings 4. Multiple heating wires 7 are fixedly connected at equal intervals on the outer wall of the protective telescopic cover 6. Multiple locking blocks 8 are fixedly connected at equal intervals on the outer wall of the two fixing rings 4. Multiple slots 9 that engage with the locking blocks 8 are opened at equal intervals on the outer wall of the two connecting seats 2. A locking component is provided between the connecting seats 2 and the fixing rings 4. The first connecting arm 171 and the second connecting arm 172 can be the connecting arms at both ends of the rotatable connecting node of the six-axis robot 17.

[0021] In use, the device inserts the fixing rings 4 at both ends of the protective telescopic cover 6 into the connecting seats 2 on the first connecting arm 171 and the second connecting arm 172, respectively. When the fixing rings 4 are inserted into the connecting seats 2, the locking blocks 8 on the outer side of the fixing rings 4 are aligned with the locking slots 9 on the connecting seats 2. Then, the two fixing rings 4 are rotated to limit the connection between the two fixing rings 4 and the two connecting seats 2, thereby fixing the two fixing rings 4 and the protective telescopic cover 6 between the two fixing rings 4. The protective telescopic cover 6 protects the six-axis robot 17 from dust at the connecting rotation nodes. At the same time, lubricating oil is filled into the protective telescopic cover 6 to lubricate the connecting rotation nodes of the six-axis robot 17. Heat is generated by the heating wire 7 to heat the lubricating oil, preventing the lubricating oil from freezing in low-temperature environments and affecting the rotation operation of each connecting rotation node. Example 2

[0022] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 5 As shown below, see details: In a preferred embodiment, the locking assembly includes a fixed base 10, a locking groove 11, a locking base 12, a locking rod 13, a connecting piece 14, a locking protrusion 15, and a locking spring 16. Multiple locking bases 12 are fixedly arranged at equal intervals on the outer wall of the connecting base 2. The locking rod 13 movably passes through the surface of the locking base 12. A stop block is fixedly connected to one end of the locking rod 13, and the stop block is located at the end of the locking rod 13 away from the connecting piece 14. A connecting piece 14 is fixedly arranged at one end of the locking rod 13, and a locking protrusion 15 is fixedly arranged on the connecting piece 14. A locking spring 16 is sleeved and connected to the outer wall of the locking rod 13, and the locking spring 16 is located between the locking base 12 and the connecting piece. Between 14, and the two ends of the locking spring 16 are fixedly connected to the locking seat 12 and the connecting piece 14 respectively. Multiple fixing seats 10 are fixedly provided on the outer wall of the fixing ring 4. The surface of the fixing seat 10 is provided with a locking groove 11 that engages with the locking protrusion 15. When the fixing ring 4 connected in the connecting seat 2 is rotated, the locking protrusion 15 will slide into the locking groove 11 on the surface of the fixing seat 10. At the same time, the locking spring 16 squeezes the connecting piece 14, so that the locking protrusion 15 is tightly engaged in the locking groove 11. The engagement of the locking protrusion 15 and the locking groove 11 can further improve the stability of the fixed connection between the two ends of the protective telescopic cover 6.

[0023] In a preferred embodiment, a first rubber gasket 3 is fixedly installed in each of the two connecting seats 2, and a second rubber gasket 5 is fixedly connected to one end of each of the two fixing rings 4 inserted into the connecting seat 2. By setting the fixing rings 4 and the second rubber gaskets 5, the sealing performance between the two ends of the protective telescopic cover 6 and the two connecting seats 2 can be improved, and the lubricating oil leakage can be avoided after the lubricating oil is poured into the protective telescopic cover 6.

[0024] In a preferred embodiment, a visual inspection camera 18 is fixedly connected to the six-axis robot 17 by bolts. The visual inspection camera 18 has an internal light and is used to detect the cleaning effect and provide feedback to control the robot to perform re-spraying or re-sweeping. A high-pressure nozzle 20 is fixedly connected to the six-axis robot 17 by a tapered tube connector 19 and a sealant. This nozzle is used to spray high-pressure de-icing agent and hot air. Furthermore, a robot thermal insulation coat can be wrapped around the six-axis robot 17 to further improve the overall antifreeze effect of the six-axis robot 17.

[0025] In this embodiment, the visual inspection camera 18 and the terminal high-pressure nozzle 20 are commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them without making any structural or functional improvements, and we will not go into detail here.

[0026] The working process of this utility model is as follows: First, the fixing rings 4 at both ends of the protective telescopic cover 6 are respectively inserted into the connecting seats 2 on the first connecting arm 171 and the second connecting arm 172. When the fixing rings 4 are inserted into the connecting seats 2, the locking blocks 8 on the outer side of the fixing rings 4 are aligned with the locking slots 9 opened on the connecting seats 2. Then, the two fixing rings 4 are rotated so that the two fixing rings 4 are limited to the two connecting seats 2, thereby realizing the fixed connection between the two fixing rings 4 and the protective telescopic cover 6 set between the two fixing rings 4. The connected protective telescopic cover 6 protects the six-axis robot 17 from dust at the connecting rotation nodes. At the same time, lubricating oil is filled into the protective telescopic cover 6 to lubricate the connecting rotation nodes of the six-axis robot 17. At the same time, heat is generated by the heating wire 7 to heat the lubricating oil, so as to prevent the lubricating oil from freezing in the low temperature environment and affecting the rotation operation of each connecting rotation node. Simultaneously, when the fixing ring 4 is rotatably connected to the connecting seat 2, the locking protrusion 15 will slide into the locking groove 11 opened on the surface of the fixing seat 10. At the same time, the locking spring 16 presses the connecting piece 14, so that the locking protrusion 15 is tightly engaged in the locking groove 11. Through the engagement of the locking protrusion 15 and the locking groove 11, the stability of the fixed connection between the two ends of the protective telescopic cover 6 can be further improved. In addition, the setting of the fixing ring 4 and the second rubber gasket 5 can improve the sealing of the connection between the two ends of the protective telescopic cover 6 and the two connecting seats 2, and prevent the lubricating oil from leaking after the protective telescopic cover 6 is filled with lubricating oil. The above is the working principle of the explosion-proof robot.
