Description

Technical Field

[0001] This utility model relates to the field of robot manufacturing technology, specifically to a protective device for industrial robots. Background Technology

[0002] An industrial robot is a mechatronic device that can perform automated operations in an industrial production environment. Through preset programs, sensor feedback, or artificial intelligence algorithms, it can perform complex operations such as handling, welding, assembly, processing, and inspection of objects, thereby replacing or assisting humans in performing repetitive, labor-intensive, and hazardous tasks.

[0003] Chinese patent publication CN213731856U discloses a utility model patent for an industrial robot protection device. This device, using multiple nozzles integrated with a housing, can spray dry powder from above to extinguish fires on the industrial robot, either directly or while it is in operation, demonstrating its safety performance. However, this design suffers from a significant technical bottleneck: the top nozzles primarily spray vertically downwards, which is inadequate for the complex three-dimensional structure of industrial robots. For example, if the fire source is located inside the robot arm joint, below the base, or obstructed by other workpieces, the downward-spraying dry powder will fail to reach the fire, leading to extinguishing failure and potentially significant damage. This predicament of "seeing the fire but not being able to ignite it" is a critical technical challenge that existing protective devices urgently need to address. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An industrial robot protective device, comprising:

[0006] The workbench has a robot body and a side plate connected to its top. A pair of triangular plates are connected to the back of the side plate. An elongated hole is opened in the middle of the inside of the side plate. A fixed sleeve is slidably connected inside the elongated hole. A lifting mechanism is provided on the inner wall of the fixed sleeve.

[0007] The front end of the fixed sleeve is provided with a steering mechanism, the outside of the steering mechanism is connected to a back plate, the front side of the back plate is connected to four fixing brackets, the front side of the four fixing brackets is fixedly connected to a cloth tube, and the front side of the cloth tube is connected to several nozzles.

[0008] A feeding mechanism is provided at the top of the fabric tube.

[0009] In one possible implementation, the lifting mechanism includes a first motor, the bottom of which is fixedly connected to a side plate, one end of the output shaft of the first motor is connected to a reciprocating lead screw, the top end of the reciprocating lead screw is rotatably connected to a first bearing seat, a ball nut assembly is connected to the outside of the reciprocating lead screw, and the outside of the ball nut assembly is fixedly connected to a fixed sleeve.

[0010] In one possible implementation, the steering mechanism includes a second bearing housing, one side of which is fixedly connected to a fixed sleeve. A shaft is rotatably connected inside the second bearing housing, and both ends of the shaft are connected to fixed plates. One side of the fixed plate is fixedly connected to a back plate.

[0011] In one possible implementation, a second motor is connected to the top of the second bearing housing, a second gear is connected to one end of the output shaft of the second motor, a first gear is meshed with the outer side of the second gear, and the inner side of the first gear is fixedly connected to the shaft.

[0012] In one possible implementation, the feeding mechanism includes a powder storage tank, a positioning frame is fitted on the outside of the powder storage tank, the bottom of the positioning frame is fixedly connected to a side plate, an air pump is connected to the top of the powder storage tank, a pressure-resistant hose is connected to one end of the discharge port of the powder storage tank, and one end of the pressure-resistant hose extends into the interior of the distribution pipe.

[0013] In one possible implementation, a first sleeve is fitted on the outer side of the shaft near the fixed plate, a second sleeve is fixedly connected to the back side of the first sleeve, and a guide rod is slidably connected inside the second sleeve, with both the upper and lower ends of the guide rod fixedly connected to the side plate.

[0014] In one possible implementation, the two arms of the back plate are distributed in a funnel shape.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. By activating the first motor, the reciprocating screw is rotated, which in turn facilitates the lifting and lowering of the ball bearing nut assembly and the fixing sleeve. At the same time, the back plate and the outer cloth tube and nozzle are also lifted and lowered. Simultaneously, the second motor is activated, which drives the second gear to rotate, which in turn facilitates the rotation of the first gear and the shaft. This allows for easy angle adjustment of the back plate and the outer cloth tube and nozzle. By rotating the angle, the dry powder is aimed at the fire source. Combined with the lifting and lowering adjustment of the spray distance, the coverage accuracy is greatly improved.

[0017] 2. By setting a pair of guide rods on the front side of the side plate and setting a slidable second sleeve on the outside of the guide rods, with the first sleeve fixedly connected to one side of the second sleeve and the first sleeve sleeved on the outside of the shaft, the combination design of the guide rods, the second sleeve and the first sleeve helps to ensure the stability of the rotation angle and improve the positioning accuracy of the nozzle.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This application provides an industrial robot protection device to solve the problems in the prior art.

[0026] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0027] like Figures 1-3 As shown, an industrial robot protective device includes:

[0028] The workbench 7 is connected to the robot body 9 and the side plate 1 on the top of the workbench 7. A pair of triangular plates 13 are connected to the back of the side plate 1. An elongated hole 8 is opened in the middle of the inside of the side plate 1. A fixed sleeve 12 is slidably connected inside the elongated hole 8. A lifting mechanism is provided on the inner wall of the fixed sleeve 12.

[0029] The front end of the fixed sleeve 12 is provided with a steering mechanism, the outer side of the steering mechanism is connected to a back plate 3, the front side of the back plate 3 is connected to four fixed brackets 19, the front side of the four fixed brackets 19 is fixedly connected to a cloth pipe 4, and the front side of the cloth pipe 4 is connected to several nozzles 5.

[0030] A feeding mechanism is provided at the top of the material distribution pipe 4.

[0031] In some examples, the lifting mechanism includes a first motor 18, the bottom of which is fixedly connected to the side plate 1. One end of the output shaft of the first motor 18 is connected to a reciprocating lead screw 14. The top end of the reciprocating lead screw 14 is rotatably connected to a first bearing seat 10. A ball nut assembly 11 is connected to the outside of the reciprocating lead screw 14. The outside of the ball nut assembly 11 is fixedly connected to a fixed sleeve 12. When the first motor 18 is turned on, the reciprocating lead screw 14 is rotated, which facilitates the lifting of the ball nut assembly 11 and the fixed sleeve 12, and at the same time, the back plate 3 and the outer fabric tube 4 and nozzle 5 are lifted.

[0032] In some examples, the steering mechanism includes a second bearing seat 22, one side of which is fixedly connected to a fixed sleeve 12. A shaft 23 is rotatably connected inside the second bearing seat 22. Both ends of the shaft 23 are connected to fixed plates 24. One side of the fixed plate 24 is fixedly connected to the back plate 3. Under the connection of the second bearing seat 22 and the shaft 23, the back plate 3 and the outer fabric tube 4 and nozzle 5 can rotate flexibly.

[0033] In some examples, a second motor 26 is connected to the top of the second bearing housing 22, and a second gear 27 is connected to one end of the output shaft of the second motor 26. A first gear 21 is meshed with the outer side of the second gear 27, and the inner side of the first gear 21 is fixedly connected to the shaft 23. When the second motor 26 is turned on, the second gear 27 is driven to rotate, which in turn drives the first gear 21 and the shaft 23 to rotate, thereby facilitating the angle adjustment of the back plate 3 and the outer fabric tube 4 and nozzle 5.

[0034] In some examples, the feeding mechanism includes a powder storage tank 16, with a positioning frame 17 fitted on the outside of the powder storage tank 16. The bottom of the positioning frame 17 is fixedly connected to the side plate 1. An air pump 15 is connected to the top of the powder storage tank 16. One end of the outlet of the powder storage tank 16 is connected to a pressure-resistant hose 2. One end of the pressure-resistant hose 2 extends into the inside of the distribution pipe 4. A valve can be installed at the end of the pressure-resistant hose 2 near the outlet of the powder storage tank 16. By opening the valve, the dry powder inside the powder storage tank 16 can be conveniently output to the inside of the distribution pipe 4 through the pressure-resistant hose 2, and finally sprayed out through the nozzle 5.

[0035] In some examples, a first sleeve 20 is fitted onto the outer side of the shaft 23 near the fixed plate 24. A second sleeve 25 is fixedly connected to the back of the first sleeve 20. A guide rod 6 is slidably connected inside the second sleeve 25. Both the upper and lower ends of the guide rod 6 are fixedly connected to the side plate 1. The combined design of the guide rod 6, the second sleeve 25, and the first sleeve 20 helps to ensure the stability of the rotation angle and improve the positioning accuracy of the nozzle 5. The sliding cooperation between the guide rod 6 and the sleeve creates an extremely stable guiding system. The ingenuity of this design lies in its effective counteracting of minor swaying and vibration that may occur during the lifting and rotation of the device, especially during emergency startup. This stability is crucial for achieving precise fire extinguishing, ensuring that the nozzle 5 can "hit the target" after the angle is adjusted, without deviation from the target due to mechanical tolerances or inertia, thus guaranteeing the realization of the core technical effect of "significantly improving coverage accuracy".

[0036] In some examples, the two arms of the backplate 3 are arranged in a funnel shape. The large-angle opening at the ends allows the dry powder to spread evenly along the inclined direction of the two arms, covering a wider area—not just for aesthetics. This design utilizes fluid dynamics principles to guide the high-pressure jet of dry powder into a wider and more uniform fan-shaped coverage area. Compared to simple straight-tube spraying, it effectively reduces the problems of excessive dry powder concentration in the central area and insufficient coverage in the edge areas, achieving maximum coverage area with minimal extinguishing agent, thus improving extinguishing efficiency and economy.

[0037] This invention utilizes a first motor 18 to rotate a reciprocating screw 14, which in turn facilitates the lifting and lowering of the ball bearing nut assembly 11 and the fixing sleeve 12. Simultaneously, it lifts and lowers the back plate 3, the outer fabric tube 4, and the nozzle 5. Simultaneously, a second motor 26 is activated, rotating a second gear 27, which in turn facilitates the rotation of the first gear 21 and the shaft 23. This allows for easy angle adjustment of the back plate 3, the outer fabric tube 4, and the nozzle 5. By rotating the angle, the dry powder is aimed at the fire source, and the lifting and lowering adjustment of the spray distance greatly improves the accuracy of coverage.

[0038] In practical applications, the advantages of this invention in collaborative operation are particularly prominent. When a fire occurs, the operator can perform combined operations based on the specific location of the fire source. For example, when the fire source is located on the lower middle side of the robot body 9, the first motor 18 can be started first. Through the transmission of the reciprocating screw 14 and the ball nut assembly 11, the entire spraying device can be quickly lowered to a position level with the fire source. Then, the second motor 26 is started, driving the gear set to rotate the back plate 3 and the nozzle 5 at a precise angle, firmly locking the dry powder spray direction to the fire source. This "dimensional reduction attack" fire extinguishing method realizes a leap from two-dimensional plane to three-dimensional space, ensuring that no matter where the fire source is hidden, it can be quickly and accurately covered, solving the problem of fire extinguishing blind spots caused by fixed angles in existing technologies.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
