[0002] During the truss plate production process, a robot is usually used to grab the steel trusses and then accurately place them on the base film on the conveyor belt. After long-term use of the robot, the joints and transmission components may wear out and become loose. This will cause the robot's positioning accuracy to decrease when grabbing and placing the steel trusses, and other problems may occur, affecting the quality of truss plate production. Therefore, regular maintenance of the robot is crucial. However, the support frame for installing the robot is usually fixed. Since the robot is located above the conveyor belt, it is relatively inconvenient to repair the robot.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] Example: Figure 1-3 As shown, the utility model provides a steel truss precision placement device for truss plate production, including a base 1, the top of the base 1 is rotatably installed with a conveyor belt 11 through two sets of symmetrically distributed support legs, the upper surface of the base 1 is fixedly installed with a bottom plate 12, the upper surface of the bottom plate 12 is fixedly installed with a truss placement platform 13 through two sets of symmetrically distributed support legs, the top of the bottom plate 12 is provided with a lifting assembly 14, the lifting assembly 14 includes two symmetrically distributed cross plates 2, the top of each cross plate 2 is fixedly installed with two symmetrically distributed support frames 21, the support frames 2 1 is located at the edge of the horizontal plate 2, and the inner wall of each support frame 21 is fixedly installed with two symmetrically distributed fixed blocks 22, and a threaded rod 23 is rotatably installed in the middle of the fixed block 22. The thread direction of each threaded rod 23 is the same, and the outer side of each threaded rod 23 is threadedly connected to a moving block 24. The moving block 24 is fixedly installed with a support frame 25 on the side close to the conveyor belt 11. The top of the support frame 25 is provided with a manipulator 20, and each support frame 21 is provided with a limiting groove 26 for use with the moving block 24 on the side close to the support frame 25.

[0017] A moving assembly 3 is provided on the side of the top of the base plate 12 away from the truss placement platform 13. The moving assembly 3 includes two symmetrically distributed hydraulic cylinders 31. The hydraulic cylinders 31 are fixed on the base plate 12. A moving plate 32 is fixedly installed on the driving end of the hydraulic cylinder 31. The moving plate 32 is fixedly connected to the cross plate 2. Two symmetrically distributed slide rails 33 are fixedly installed on the top of the base plate 12. The moving plate 32 and the cross plate 2 are slidably sleeved on the slide rails 33.

[0018] The lifting assembly 14 also includes two sets of symmetrically distributed first bevel gears 27. The first bevel gears 27 are fixed to the top of the threaded rod 23. The outer side of the first bevel gears 27 is meshed with second bevel gears 28. Each second bevel gear 28 rotates in the same direction. A rotating shaft 29 is fixedly installed in the middle of every two second bevel gears 28. The rotating shaft 29 rotates through the support frame 21, and the rotating shaft 29 is on the X-axis.

[0019] The length of the truss placement platform 13 should be smaller than the distance between the two support frames 21 of the X-axis, and the length of the conveyor belt 11 should be longer than the distance between the two support frames 21 of the X-axis, which makes it easier for the moving component 3 to drive the lifting component 14 and the manipulator 20 to move in the opposite direction of the truss placement platform 13, thereby realizing maintenance of the manipulator 20.

[0020] A first baffle 4 is fixedly installed on one side of the bottom plate 12 close to the movable plate 32. By setting the first baffle 4, when the manipulator 20 needs to be repaired, the lifting assembly 14 and the manipulator 20 are driven to move in the opposite direction of the truss placement platform 13 through the movable assembly 3. When the horizontal plate 2 in the lifting assembly 14 is in contact with the first baffle 4, it means that there is no need to move the lifting assembly 14 and the manipulator 20, and they have reached the place where the manipulator 20 can be maintained. At the same time, it also avoids contact between the two support frames 21 and the conveyor belt 11 near the side of the truss placement platform 13.

[0021] A second baffle 5 is fixedly installed on one side of the bottom plate 12 close to the truss placement platform 13. By setting the second baffle 5, after the manipulator 20 is maintained, the lifting assembly 14 and the manipulator 20 are driven to move back through the moving assembly 3. When the horizontal plate 2 in the lifting assembly 14 is in contact with the second baffle 5, it means that the lifting assembly 14 and the manipulator 20 do not need to be moved and have reached the original position, so that it is clear to know to what position the moving assembly 3 moves and can stop.

[0022] The two rotating shafts 29 are connected by a toothed synchronous belt transmission. A motor is fixedly installed on one side of one of the support frames 21, and the driving end of the motor is fixedly connected to one of the rotating shafts 29. By setting a motor (not numbered in the figure), when the motor is started, it drives one of the rotating shafts 29 to rotate. Then, the two rotating shafts 29 are connected by a toothed synchronous belt transmission, so that the two rotating shafts 29 rotate at the same time, driving the corresponding second bevel gear 28 to rotate, thereby driving the first bevel gear 27 and the threaded rod 23 to rotate.

[0023] The hydraulic cylinder 31 is located directly below the conveyor belt 11 , which saves space and facilitates maintenance of the manipulator 20 .

[0024] Working principle: In actual use, when the manipulator 20 needs to be maintained, first start the hydraulic cylinder 31 in the moving assembly 3 to drive the moving plate 32 to move on the slide rail 33. As the moving plate 32 moves, the cross plate 2 in the lifting assembly 14 is driven to move on the slide rail 33, thereby realizing the movement of the lifting assembly 14 and the manipulator 20. When it moves to the position where the manipulator 20 can be maintained, the corresponding second bevel gear 28 is driven to rotate by the rotation of the rotating shaft 29. As the second bevel gear 28 rotates, the corresponding first bevel gear 2 7. The threaded rod 23 rotates, and the moving block 24 is limited by the limiting groove 26. The rotation of the threaded rod 23 drives the moving block 24, the support frame 25, and the manipulator 20 to move downward. When the bottom end of the moving block 24 is in contact with the upper surface of the inner wall of the limiting groove 26, it means that there is no need to move downward. At the same time, it also means that the support frame 25 is in contact with the conveyor belt 11, and it also means that the position where the manipulator 20 can be maintained has been reached, thereby facilitating the maintenance of the manipulator 20. No other tools are needed to maintain the manipulator 20 at a high position.

[0025] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
