Description

Technical Field

[0001] This utility model relates to the field of industrial robot technology, specifically to an industrial robot with protective functions. Background Technology

[0002] An industrial robot is a multi-jointed manipulator or multi-degree-of-freedom robotic device designed for industrial applications, capable of automatically performing various tasks under programmed control.

[0003] According to a public notice (Announcement No.: CN218534623U) of an industrial vision robot with protective functions, the aforementioned application uses an auxiliary protective component. Multiple sets of rotatable extension brackets can be used, allowing the number of extension brackets to be freely adjusted according to the distance between two sets of conveyor belts. Simultaneously, the threaded connection of auxiliary threaded holes and positioning bolts allows the positioning bolts to move quickly downwards and use clamping force to fix the extension brackets. Furthermore, the insertion of T-shaped plates and slots allows for the rapid installation of protective elastic bands. Combined with the support pillars, this forms a protective wall that effectively blocks workers, preventing them from accidentally entering the rotating working range of the industrial vision robot and avoiding injuries, thus improving safety.

[0004] However, in practical applications, this protective component still has some shortcomings. Specifically, the length of its extension bracket is fixed and cannot be adjusted according to different processing environments and work requirements. This means that the protective component may not be fully adaptable to processing equipment of different sizes and layouts, thus affecting its protective effect. For example, in some processing environments, due to the large distance between devices, the fixed extension bracket may not provide sufficient protection; while in other processing environments, where the distance between devices is small, an excessively long extension bracket may interfere with the normal operation of the robot.

DETAILED DESCRIPTION

[0025] As shown in Figures 1-5 The utility model provides a kind of industrial robot with protection function, including fixed seat 1, the top of fixed seat 1 is equipped with robot body 2, the bottom of fixed seat 1 is fixed with base 3, the surface of fixed seat 1 is provided with protection assembly 4 and limiting component 5;Protection assembly 4 includes: fixed shell 40, cavity 41, round plate 42, connection hole 43, short rod 44, fixed rod 45, universal wheel 46, long rod 47, sleeve ring 48, transmission part 49, gear groove 490, fixed plate 491, rotating rod 492, gear 493.

[0026] The fixed housing 40 is fixed to the surface of the fixed base 1. A cavity 41 is formed inside the fixed housing 40. A circular plate 42 is rotatably connected to the inner wall of the cavity 41. A connecting hole 43 is formed on the surface of the circular plate 42. A short rod 44 abuts against the inner wall of the connecting hole 43. A fixed rod 45 is fixed to the surface of the short rod 44. The end of the fixed rod 45 away from the short rod 44 passes through the fixed housing 40, and the fixed rod 45 is slidably connected to the short rod 44. A caster wheel 46 is installed at the bottom of the end of the fixed rod 45 away from the short rod 44. A long rod 47 is fixed to the top of the end of the fixed rod 45 away from the short rod 44. A collar 48 is fixed to the surface of the long rod 47. The protective assembly 4 also includes a transmission component 49, which includes a toothed groove 490. The toothed groove 490 is open... A fixed plate 491 is fixed to the bottom of the fixed shell 40 on the surface of the circular plate 42. A rotating rod 492 is provided on the surface of the fixed plate 491. The rotating rod 492 passes through the fixed plate 491 and is rotatably connected to the fixed plate 491. A gear 493 is fixed to the top of the rotating rod 492. The gear 493 passes through the fixed shell 40 and meshes with the tooth groove 490. The connecting hole 43 is arc-shaped. The circular plate 42 drives the connecting hole 43 to rotate synchronously. The inner wall of the connecting hole 43 abuts against the surface of the short rod 44. The short rod 44 and the fixed rod 45 move radially synchronously. The fixed rod 45 drives the universal wheel 46 to move away from the fixed seat 1, which facilitates the adjustment of the diameter of protection required for different needs and adapts to different working needs and environments.

[0027] The limiting component 5 includes a slot 50, which is formed on the surface of the rotating rod 492. A fixing frame 51 is fixed to the bottom of the fixing plate 491. A block 52 is slidably connected to the inner wall of the fixing frame 51. A spring 54 is fixed to the surface of the block 52. The end of the spring 54 away from the block 52 is fixed to the inner wall of the fixing frame 51. An insertion hole 53 is formed on the surface of the fixing frame 51 and the block 52. The cross-section of the end of the block 52 away from the spring 54 is triangular. When the gear 493 rotates, the inner wall of the slot 50 abuts against the surface of the block 52. Through the spring 54, the block 52 moves back and forth into the fixing frame 51. When the position is adjusted, the pin is inserted into the insertion hole 53 to limit the block 52, thereby limiting the rotating rod 492 and the gear 493. At this time, the circular plate 42 cannot continue to rotate, which can prevent the tension of the protective belt from returning and causing the fixing rod 45 to reset. At the same time, it can prevent external accidental contact with the gear 493, which would affect its protection range.

[0028] In use, the elastic protective strap is fitted onto the surface of the collar 48. Rotating the gear 493 causes the toothed groove 490 to rotate synchronously, and the circular plate 42 causes the connecting hole 43 to rotate synchronously. The inner wall of the connecting hole 43 abuts against the surface of the short rod 44, causing the short rod 44 and the fixed rod 45 to move radially synchronously. At this time, the fixed rod 45 moves the universal wheel 46 away from the fixed base 1, facilitating adjustment of the diameter for different protection needs. Simultaneously, as the gear 493 rotates, the inner wall of the slot 50 abuts against the surface of the locking block 52, allowing the locking block 52 to move into the fixed frame 51. When the spring 54 is compressed, and the position of the locking block 52 is parallel to the locking groove 50, the spring 54 is released, causing the locking block 52 to enter the locking groove 50. When the gear 493 rotates, the rotating rod 492 continues to rotate. At this time, the locking block 52 moves back and forth into the fixed frame 51. When the position is adjusted, the pin is inserted into the insertion hole 53 to limit the locking block 52, thereby limiting the rotating rod 492 and the gear 493. At this time, the circular plate 42 cannot continue to rotate, which can prevent the tension of the protective belt from returning to the original position and causing the fixed rod 45 to reset. At the same time, it can prevent external accidental contact with the gear 493, which would affect its protection range.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
