Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary robot welding carriages. Specifically, it relates to a display screen flipping mechanism suitable for robot welding carriages. Background Technology

[0002] Robotic welding carts are already in use in many automobile factories. Robotic welding carts can achieve high precision and high efficiency while avoiding the risk of burns from sparks during manual operation. In the current technology, the carts welded by robots still need to be debugged in the subsequent process. The debugging involves various parts of the cart, and workers need to use computers to perform debugging operations near each location.

[0003] In the existing technology, a computer is placed on a mobile cart and operated by moving it to different locations. This requires ground space, and in some locations the mobile cart cannot reach, so staff have to carry the computer to operate it. They also need to keep the computer stable while debugging and observing the operation, which is very inconvenient. Utility Model Content

[0023] Example:

[0024] See attached Figures 1-3This embodiment provides a display screen flipping mechanism suitable for a robotic welding trolley, including a display mounting assembly for mounting a computer display screen 6 and a keyboard and mouse, and a display rotation bracket assembly. This bracket assembly is connected to the display mounting assembly and fixed above the trolley production line, and can drive the display mounting assembly to rotate, covering a 360-degree area above the trolley's horizontal plane. Specifically, the display mounting assembly includes a display unit and a mounting frame 1. The display unit includes a computer display screen 6 and a keyboard and mouse, placed in a storage unit on the mounting frame 1. The display rotation bracket assembly includes a fixing unit and a rotation unit. The fixing unit is stably connected above the trolley via a fixed connection; for example, a bracket above the trolley or the ceiling can be used as a fixing point, secured by screws or other methods. The rotation unit is mounted on the fixing unit and connected to the mounting frame 1, driving it to rotate. This allows for debugging work at various positions on the trolley. The operator does not need to bear the weight and balance of the computer; they only need to operate the rotation unit to rotate the mounting frame 1 above the position on the trolley requiring debugging, and then perform the debugging work. After completion, the bracket is adjusted to another direction to continue debugging.

[0025] In this embodiment, the fixing unit includes a fixing seat 2, which has a corresponding threaded hole. The threaded hole is provided on the bracket above the ceiling or the trolley, and then the fixing seat 2 is fixed above the trolley by screws.

[0026] In this embodiment, the fixed base 2 is provided with a bearing seat, and the rotary unit includes a rotating shaft 3. The rotating shaft 3 is provided with a bearing 4 and is connected to the fixed base 2 through the bearing seat. One end of the rotating shaft 3 extends outside the fixed base 2. The bearing 4 allows the rotating shaft 3 to rotate relative to the fixed base 2. The rotary unit also includes a cantilever 5. One end of the cantilever 5 is fixedly connected to the rotating shaft 3, and the other end is fixedly connected to the mounting frame 1. The mounting frame 1 and the computer display screen 6 on the mounting frame 1 can rotate around the fixed base 2, thereby adjusting the position of the computer.

[0027] In this embodiment, the storage unit on the mounting frame 1 includes a receiving cavity in the upper half of the mounting frame 1 and a rotatable support plate in the lower half. The receiving cavity is used to place the computer display screen 6, and the receiving cavity has an opening to facilitate viewing the content of the display screen 6. The rotatable support plate is used to place the keyboard and mouse, and includes a base plate 7 and two hinge rods 8. The bottom sides of the base plate 7 are hinged to the bottom sides of the mounting frame 1. The base plate 7 can be manually rotated around the hinge point to adjust its state. When the base plate 7 is rotated to the vertical direction, that is, parallel to the mounting frame 1, it fits in the lower half of the mounting frame 1, which is the storage state and occupies little space. When the base plate 7 is rotated to the horizontal direction, that is, perpendicular to the mounting frame 1, it is the working state, and the horizontally placed keyboard and mouse are convenient for the operator to operate. To further improve the stability of the base plate 7, a hinge point is provided at the middle position of one side of the base plate 7. Two hinge rods 8 are hinged together, with one end hinged to the hinge point at the middle position of one side of the base plate 7 and the other end hinged to the mounting bracket 1. This facilitates the rotation of the base plate 7 and provides a certain amount of tension when the base plate 7 is horizontal, thereby improving stability. The rotation angle of the base plate 7 is less than or equal to 90 degrees to prevent the base plate 7 from tilting downwards when it exceeds 90 degrees, which could easily cause the keyboard to slip. The rotation angle can be limited by the length of the hinge rods 8.

[0028] In this embodiment, the bottom of the base plate 7 in the vertical direction is provided with a limiting groove 9, which limits the keyboard when the base plate 7 is in the vertical state. It can rotate with the base plate 7 during the next rotation. The sides of the base plate 7 are provided with upward protruding strips 10 to increase protection and prevent the keyboard and mouse from slipping under certain conditions.

[0029] In this embodiment, a locking unit is also included for locking the cantilever 5 after it rotates. The specific locking unit includes a locking screw 11 and locking holes 12. Several locking holes 12 are provided, which can be evenly arranged around the base 2 or unevenly arranged around the base 2 depending on the specific working position. A threaded hole is provided at the end of the cantilever 5 closest to the base 2, and a locking screw 11 is fitted into the threaded hole. Locking is achieved by turning the locking screw 11 to engage with the locking hole 12. A limiting block 13 is provided on the locking screw 11. The diameter of the portion with the limiting block 13 is larger than that of the threaded hole. When the locking screw 11 extends and engages with the locking hole 12, the limiting block 13 gradually approaches the threaded hole and prevents the locking screw 11 from extending further. At this point, the locking screw 11 is just engaged with the locking hole 12. The operator can determine whether it is locked by visually observing whether the limiting block 13 is in contact with the threaded hole or by feeling that the locking screw 11 cannot be turned.

[0030] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
