[0048] This utility model provides an improved modular teaching robot system. The technical solution of this utility model is as follows:

[0049] like Figures 1-10 As shown, a modular teaching robot system includes:

[0052] Circular seat 12, which is rotatably connected to housing 5;

[0053] An annular seat 6 is rotatably mounted on a circular seat 12. Both the annular seat 6 and the circular seat 12 have multiple grooves 14 on their side walls.

[0054] Multiple through holes 15 are formed on the side wall of the annular seat 6;

[0060] Furthermore, the clamping module includes:

[0061] The annular plate 8 has multiple first rods 16 fixed to its sidewalls, and the first rods 16 pass through the through holes 15. The first rods 16 are adapted to the limiting holes.

[0062] Multiple clamping units are fixed at equal intervals on the side wall of the annular plate 8;

[0063] The first plate 7 is rotatably mounted on the inner wall of the annular plate 8, and multiple clamping components are connected to the first plate 7.

[0064] Furthermore, the clamping unit includes:

[0065] Connecting plate 18, connecting plate 18 and annular plate 8 are fixed;

[0066] Connecting rod 19, connecting rod 19 and connecting plate 18 are slidably connected;

[0068] Link 21, one end of which is rotatably connected to clamping block 20, and the other end of which is rotatably connected to first plate 7.

[0069] During clamping, the circular base 12 rotates, and the first magnet 13 on the circular base 12 and the second magnet 17 on the first plate 7 drive the first plate 7 to rotate. During the rotation of the first plate 7, the clamping block 20 moves through the connecting rod 21. Under the restriction of the connecting plate 18 and the connecting rod 19, the clamping block 20 moves along a straight line. The clamping work is achieved by the multiple clamping blocks 20 approaching each other.

[0070] Furthermore, the transmission module includes:

[0071] The second plate 9 has multiple second rods 22 fixed to its side wall, and the second rods 22 are adapted to the groove 14.

[0072] Mounting plate 10 is fixed to the side wall of the second plate 9.

[0073] By fixing experimental tools such as stirring rods onto the mounting plate 10, the stirring rods can be rotated when the second plate 9 rotates, thus assisting in the stirring process.

[0074] Furthermore, multiple first magnets 13 are fixed to the side wall of the circular base 12, multiple second magnets 17 are fixed to the side wall of the first plate 7, and multiple third magnets 23 are fixed to the side wall of the second plate 9.

[0080] Furthermore, the second arm 3 has a mounting groove at its end, the base 4 is rotatably mounted in the mounting groove, and the first motor output shaft in the base 4 is fixed to the inner wall of the mounting groove.

[0081] Specifically, the working principle is as follows: During use, the operation of the second motor and the rotation of the base 1 and the connecting seat drive the first arm 2 to rotate. The operation of the third motor in the first arm 2 and the rotation between the first arm 2 and the connecting seat adjust the angle between the first arm 2 and the connecting seat. The operation of the fourth motor in the second arm 3 and the rotation between the first arm 2 and the second arm 3 adjust the angle between the second arm 3 and the first arm 2. The operation of the first motor in the base 4 and the rotation between the base 4 and the mounting groove adjust the angle between the base 4 and the second arm 3. The operation of the first motor in the housing 5 drives the circular base 12 to rotate.

[0082] In summary, the circular base 12 can be moved at multiple angles and in multiple directions to meet various experimental needs in the teaching process;

[0083] When the robot is needed to assist in clamping, bring the annular plate 8 close to the circular seat 12, and make the first rod 16 on the annular plate 8 pass through the through hole 15 and at the same time pass through the limiting hole on the limiting seat 11.

[0084] During clamping, the circular base 12 rotates, and the first magnet 13 on the circular base 12 and the second magnet 17 on the first plate 7 drive the first plate 7 to rotate. During the rotation of the first plate 7, the clamping block 20 moves through the connecting rod 21. Under the restriction of the connecting plate 18 and the connecting rod 19, the clamping block 20 moves along a straight line. The clamping work is achieved by the multiple clamping blocks 20 approaching each other.

[0085] When the robot is needed to assist in stirring, the annular plate 8 can be removed, and the second plate 9 can be brought close to the circular seat 12, so that the second rod 22 on the second plate 9 passes through the hole formed by the circular seat 12 and the groove 14 on the annular seat 6. Then, as the circular seat 12 rotates, the second plate 9 can be rotated by the groove 14 and the second rod 22. According to specific needs, experimental tools such as stirring rods can be installed on the mounting plate 10 to assist in stirring and other work.
