Description

Technical Field

[0001] The utility model relates to the technical field of industrial robots, in particular to a welding robot with a wire harness protection mechanism. Background Art

[0002] An industrial robot is a multi-joint manipulator or multi-degree-of-freedom machine device used in the industrial field. Among them, the one used for welding is also called a welding robot. At present, in many industrial robots including welding robots, the various components are mostly connected by wires and pipelines. The routing methods of these wires and pipelines are mainly divided into external routing and internal routing.

[0003] However, most of the existing external wiring robots use fixed buckles and strips to perform "multi-point" fixation on wires and pipelines. Under such a fixing method, the fixed parts of the wires and pipelines are usually difficult to move. This will cause the line to be detached from the fixed points or the line to be too loose when the robot body moves, because the line cannot be relaxed or tightened with the robot body. When the robot body is working, the line swings back and forth, affecting the operation. Therefore, a welding robot with a wire harness protection mechanism is proposed. Utility Model Content

[0010] Preferably, a torsion spring is movably sleeved on the surface of the rotating shaft located inside the box cover, and two ends of the torsion spring are fixedly connected to the surface of the rotating shaft and the inside of the box cover respectively.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

DETAILED DESCRIPTION

[0020] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0021] See also Figure 1-4 The utility model provides a technical solution: a welding robot with a wire harness protection mechanism, comprising a base 3, a second working arm 2 is arranged on the upper part of the base 3, a first working arm 1 is arranged at one end of the second working arm 2 away from the base 3, a storage frame 5 is fixedly connected to the surface of the second working arm 2, a box cover 4 is connected to the surface of the storage frame 5 through a hinge, so as to close the storage frame 5, and at the same time, through the arrangement of the box cover 4, the staff can carry out wiring in the storage frame 5, thereby improving the convenience of using the device.

[0022] A buckle 6 is provided between the box cover 4 and the storage frame 5 for locking the box cover 4 and the storage frame 5. The buckle 6 is a conventional technical means and will not be explained in detail here.

[0023] Both ends of the inner wall of the storage frame 5 are rotatably connected to the first pulley 13, and the setting of the first pulley 13 facilitates the entry and exit of the wire harness, so that the wire harness will not be bent at the exit of the storage frame 5, reducing the friction between the wire harness and the inner wall of the storage frame 5, and avoiding the situation where the wire harness is pulled when the first working arm 1 is working.

[0024] The inner wall of the storage frame 5 is provided with equidistantly arranged slide grooves 17, the inner wall of the slide groove 17 is slidably connected with a moving block 15, the surface of the moving block 15 is rotatably connected with a second pulley 14, and two adjacent moving blocks 15 are staggered, thereby extending the wiring length of the wire harness in the storage frame 5 and achieving the purpose of storing the wire harness.

[0025] A spring 16 is fixedly connected to the surface of the moving block 15, and one end of the spring 16 away from the moving block 15 is fixedly connected to the inner wall of the slide groove 17. The spring 16 is then set to reset the moving block 15. At the same time, the elastic force of the spring 16 can be used to expand the wire harness in the storage frame 5, so that the wire harness is in a taut state, thereby avoiding the messy arrangement of the wire harness in the storage frame 5 and improving the use effect of the device.

[0026] Furthermore, both sides of the two ends of the storage frame 5 are fixedly connected with fixed plates 7, and a first conveying roller 8 is rotatably connected between the two fixed plates 7. Through the setting of the first conveying roller 8, the bending of the wire harness is buffered, so that the wire harness presents an arc bend on the first conveying roller 8, thereby avoiding the wire harness from directly bending at a ninety-degree angle, which causes the line in the wire harness to be easily broken, thereby ensuring the service life of the wire harness. Both ends of the box cover 4 are rotatably connected with a rotating shaft 11, and the end of the rotating shaft 11 away from the box cover 4 is fixedly connected with a mounting frame 10, and the inner wall of the mounting frame 10 is rotatably connected with two second conveying rollers 9, and then the setting of the two second conveying rollers 9 can respectively restrain the two ends of the wire harness between the two second conveying rollers 9, thereby avoiding the random swinging of the two ends of the wire harness and improving the wiring effect of the device.

[0027] The surface of the rotating shaft 11 inside the box cover 4 is movably sleeved with a torsion spring 12 , and the two ends of the torsion spring 12 are respectively fixedly connected to the surface of the rotating shaft 11 and the inside of the box cover 4 to reset the rotating shaft 11 .

[0028] Specifically, when wiring, open the box cover 4, wind the wire harness around the second pulley 14 in sequence, then wind the two ends of the wire harness around the first pulley 13 respectively, expose the two ends of the wire harness, then pass the two ends of the wire harness through the bottom of the first conveyor roller 8, then cover the box cover 4, then pass the two ends of the wire harness through the gap between the two second conveyor rollers 9 respectively, and then connect the two ends of the wire harness to the first working arm 1 and the peripheral equipment respectively, so that the wiring of the wire harness is completed, and then when the first working arm 1 swings, the first working arm 1 pulls the wire harness, and the wire harness squeezes and pushes the inner wall of the second conveyor roller 9, so that the second conveyor roller 9 and the mounting frame 10 are skewed, thereby driving the rotating shaft 11 to rotate in the box cover 4, and twisting the torsion spring 12, so that the two second conveyor rollers 9 and the mounting frame 10 can swing in the same direction as the swing of the wire harness, thereby reducing the deviation angle between the wire harness and the second conveyor roller 9, thereby avoiding The inner wall of the second conveying roller 9 bends the wire harness at an excessively large angle, causing damage to the line inside the wire harness. At the same time, the pulling of the second conveying roller 9 tightens the relatively tight wire harness in the storage frame 5 again, and then the wire harness pushes the inner wall of the second pulley 14 inside the storage frame 5, thereby driving the second pulleys 14 on both sides to approach the center line of the storage frame 5 and compressing the spring 16. The second pulleys 14 on both sides approach each other, thereby shortening the distance between the two second pulleys 14, and then relaxing the wire harness, so that the wire harness can be relaxed as the first working arm 1 works, so that the device can relax the wire harness as the mechanical arm swings while the wire harness is bound and fixed, thereby ensuring the normal operation of the mechanical arm, improving the wiring effect of the device, and improving the use effect of the device, which is worthy of promotion. Similarly, when the second working arm 2 swings, the movement of the wire harness in the storage frame 5 is the same as the above step.

[0029] Working principle: When the first working arm 1 swings, the first working arm 1 pulls the wire harness, and the wire harness squeezes and pushes the inner wall of the second conveyor roller 9, so that the second conveyor roller 9 and the mounting frame 10 are skewed, thereby driving the rotating shaft 11 to rotate in the box cover 4 and causing the torsion spring 12 to twist, so that the two second conveyor rollers 9 and the mounting frame 10 can swing in the same direction as the swing of the wire harness. At the same time, the pulling of the second conveyor roller 9 tightens the relatively tight wire harness in the storage frame 5 again, and then the wire harness pushes the inner wall of the second pulley 14 inside the storage frame 5, thereby driving the second pulleys 14 on both sides to approach the center line of the storage frame 5 and compressing the spring 16. The second pulleys 14 on both sides approach each other, thereby shortening the distance between the two second pulleys 14, and then relaxing the wire harness.

[0030] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
