Description

Technical Field

[0001] The utility model relates to the technical field of robots, in particular to a calligraphy robot. Background Art

[0002] Calligraphy robots are intelligent robots developed by researchers specifically for calligraphy writing. As a branch of robots, calligraphy robots have a relatively short research and development history and are generally used to demonstrate the charm of calligraphy writing and for teaching basic calligraphy.

[0003] In actual work, calligraphy robots with existing technology are small-scale and relatively sophisticated, and can handle writing simple fonts, but there are still the following two problems:

[0004] When writing, the calligraphy robot needs to simulate the writer's constant movement, but the placement table for placing paper is generally fixed, so after the position is changed, the position of the paper needs to be manually adjusted to adapt to the writing position of the calligraphy robot, which is very inconvenient;

[0005] During the writing process of the calligraphy robot, the placement table needs to change its position, and the traditional paper pressing table has the risk of sliding when used, causing the paper to tilt or wrinkle, which in turn affects the writing of the calligraphy robot. It requires manual supervision and adjustment at any time, which is very inconvenient.

[0006] Therefore, the utility model provides a calligraphy robot. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-Figure 5 As shown, this embodiment provides a technical solution: a calligraphy robot, including a conveyor belt 1, a chassis 10, a threaded shaft 4 and a coupling 6, a mounting plate 2 is fixedly installed on the top sliding part of the conveyor belt 1, a robot body 3 is fixedly installed on the top of the mounting plate 2 by bolts, two support brackets 7 are symmetrically arranged at the bottom of the conveyor belt 1, and a brush 11 is fixed at the output end of the robot body 3; the threaded shaft 4 is arranged below the conveyor belt 1, and both ends of the threaded shaft 4 are connected to the driving mechanism 5 through the coupling 6; the threads on the outer surface of the threaded shaft 4 are arranged in opposite and symmetrical manner, and the outer surface of the threaded shaft 4 is symmetrically threaded with a screw hole slider 13, and the inner wall of the screw hole slider 13 A limit rod 14 is inserted, and both ends are fixedly connected to the outer shell of the driving mechanism 5 respectively; a plurality of rolling wheels 12 are arranged at the bottom of the chassis 10, and the plurality of rolling wheels 12 form a group of three, which are divided into four groups and are symmetrically arranged at the bottom of the chassis 10, a disassembly structure 9 is arranged between the chassis 10 and the screw hole slider 13, and a paper fixing structure 8 is arranged on the top of the chassis 10; the paper fixing structure 8 includes a rectangular plate 85, and the inner wall of the rectangular plate 85 is threadedly connected with a second screw rod 86, and the bottom of the second screw rod 86 is rotatably connected with a clamping plate 87, and the top of the clamping plate 87 is fixedly connected with a sliding rod 88, and the sliding rod 88 is slidably arranged on the inner wall of the rectangular plate 85.

[0029] Further, such as Figure 1As shown: the conveyor belt 1 is a rack slide, the robot body 3 is a two-axis or three-axis robot, and the rack slide conveyor belt 1 can be matched with the two-axis or three-axis robot to meet the writing needs on the horizontal plane. The rack slide is more stable during use, and the paper fixing structure 8 on the chassis 10 can fix the paper, so that the two-axis or three-axis robot will not deviate or wrinkle when writing, thereby meeting the writing needs.

[0030] The above solution still has the problem that when the paper sizes are different, the clamping plate 87 at the fixed position cannot clamp. Figure 2 As shown: a rectangular frame 81 is fixedly connected to one side of the chassis 10, and a first screw rod 82 is fixedly connected between the two sides of the inner wall of the rectangular frame 81. The outer surface of the first screw rod 82 is symmetrically threadedly connected to two screw hole blocks 83, and the threads at both ends of the first screw rod 82 are arranged symmetrically in opposite directions. The screw hole block 83 is slidably connected to the inner wall of the rectangular frame 81, and a connecting rod 84 is fixedly connected to the top of the screw hole block 83. The other end of the connecting rod 84 is fixedly connected to one side of the rectangular plate 85. The first screw rod 82 can drive the screw hole block 83 to move, and then drive the connecting rod 84 to move, so that the connecting rod 84 can drive the rectangular plate 85 to move, and then drive the clamping plate 87 to move, and the horizontal position of the clamping plate 87 can be adjusted, so that papers of different sizes can be fixed and clamped.

[0031] The above solution still has the problem that the chassis 10 is directly placed on the screw hole slider 13 and is unstable. Figure 4 and Figure 5 As shown, the disassembly structure 9 includes a rectangular clamping block 91 and a rectangular clamping frame 92. The bottom of the rectangular clamping block 91 is fixedly connected to the screw hole slider 13, and the top of the rectangular clamping frame 92 is fixedly connected to the bottom of the chassis 10. The rectangular clamping block 91 can be stuck into the inner wall of the rectangular clamping frame 92. A circular groove 93 is provided on one side of the rectangular clamping block 91. A fixing rod 94 is fixedly connected to the inner wall of the circular groove 93. A sliding clamping block 95 is slidably connected to one end of the fixing rod 94. A reset spring 96 is sleeved on the outer surface of the fixing rod 94. A circular clamping hole 97 adapted to the sliding clamping block 95 is provided on one side of the rectangular clamping frame 92. By arranging the rectangular clamping block 91 and the rectangular clamping frame 92, the chassis 10 can be fixed to the screw hole slider 13, and then the fixing can be made more stable under the action of the sliding clamping block 95 and the circular clamping hole 97. Disassembly only requires pressing the sliding clamping block 95, which is more convenient and quicker than traditional bolt fixing.

[0032] Working principle:

[0033] like Figure 1-5 As shown:

[0034] When in use: fix the writing brush 11 to the robot body 3, start the conveyor belt 1 and the robot body 3, so that the conveyor belt 1 can drive the robot body 3 to move horizontally, and then cooperate with the robot body 3 to write on the chassis 10;

[0035] When the paper needs to be moved, the driving mechanism 5 is started to rotate the threaded shaft 4, thereby causing the screw hole slider 13 to move, and then the chassis 10 can be driven to move;

[0036] When the chassis 10 needs to be disassembled, the sliding block 95 is pressed to slide on the outer surface of the fixing rod 94 and then separated from the circular clamping hole 97, and the chassis 10 is pulled upward to separate the rectangular clamping block 91 from the rectangular clamping frame 92;

[0037] When the paper needs to be clamped, the first screw 82 is rotated so that the first screw 82 drives the screw hole block 83 to move, thereby adjusting the position of the clamping plate 87 to a suitable position;

[0038] At this time, the second screw rod 86 is rotated to make the clamping plate 87 move downward, and at the same time, the sliding rod 88 slides on the inner wall of the rectangular plate 85 to clamp the paper.

[0039] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
