[0028] S1. When the projector body needs to be used, the output end of the second motor is started to rotate, and the first screw is driven to rotate by the output end of the second motor. The first screw is driven to move the first nut on the surface of the first screw, and the movement of the first nut drives the connecting seat to move. When the first screw rotates forward, the first nut moves downward on the surface of the first screw, and the connecting seat is driven to move downward by the downward movement of the first nut, and the projector body is driven to move downward by the movement of the connecting seat. When the first nut moves to the bottom of the first screw, the second motor can be turned off, and the projector body is extended from the installation box at this time, and then projection teaching can be carried out;

[0029] S2. When the position of the projector body needs to be adjusted, the output end of the third motor is started to rotate, and the second screw is driven to rotate by the rotation of the output end of the third motor, and the second nut is driven to move on the surface of the second screw by the rotation of the second screw, and the fixed block is driven to move by the movement of the second nut, so that the sliding sleeve and the mounting box are driven to move by the movement of the fixed block, so as to facilitate the movement of the projector body, and the left and right position of the projector body is controlled by adjusting the forward and reverse rotation of the second screw, thereby optimizing the convenience of its projection teaching;

[0031] Beneficial Effects

[0032] Compared with the prior art, the advantages of the present invention are:

[0033] (1) In this scheme, when the projector body needs to be used, the output end of the second motor is started to rotate, and the first screw is driven to rotate by the output end of the second motor. The first screw is driven to move the first nut on the surface of the first screw, and the movement of the first nut drives the connecting seat to move. When the first screw rotates forward, the first nut moves downward on the surface of the first screw, and the connecting seat is driven to move downward by the downward movement of the first nut. The projector body is driven to move downward by the movement of the connecting seat. When the first nut moves to the bottom of the first screw, the second motor can be turned off. At this time, the projector body is extended from the installation box, and then projection teaching can be carried out.

[0034] (2) In this scheme, when the position of the projector body needs to be adjusted, the output end of the third motor is started to rotate, and the second screw is driven to rotate by the output end of the third motor, and the second nut is driven to move on the surface of the second screw by the rotation of the second screw, and the fixed block is driven to move by the movement of the second nut, thereby driving the sliding sleeve and the mounting box to move through the movement of the fixed block, so as to facilitate the movement of the projector body, and the left and right position of the projector body is controlled by adjusting the forward and reverse rotation of the second screw, thereby optimizing the convenience of projection teaching.

[0035] (3) In this scheme, when it is necessary to clean the dust on the main lens of the projector, the output end of the first motor is started to rotate, and the rotation of the output end of the first motor drives the rotating wheel to rotate. Since the output end of the first motor is located at the eccentric position of the rotating wheel, the rotation of the output end of the first motor will drive the rotating wheel to make an eccentric movement. The eccentric movement of the rotating wheel intermittently pushes the push plate to move to the left, and the movement of the push plate pushes the mounting plate and the cleaning brush to move to the left. The movement of the push plate compresses the spring. When the first motor does not push the push plate to move, the spring is reset by its own elastic action, thereby pushing the push plate to move to the right. The eccentric movement of the rotating wheel and the elastic action of the spring facilitate the reciprocating movement of the push plate. The reciprocating movement of the push plate drives the mounting plate and the cleaning brush to reciprocate. The reciprocating movement of the cleaning brush facilitates the cleaning of dust on the main lens of the projector, thereby preventing dust from interfering with the projection teaching of the projector main body.

[0036] (4) In this solution, the guide hole is provided to facilitate sliding cooperation with the guide plate. The sliding cooperation between the guide hole and the guide plate facilitates the stable up and down movement of the projector body. BRIEF DESCRIPTION OF THE DRAWINGS

10. An intelligent projection teaching method, characterized in that: The intelligent projection teaching system according to claim 9 is used, comprising the following steps: S1. When the projector body (7) needs to be used, the output end of the second motor (23) is started to rotate, and the first screw rod (24) is driven to rotate by the rotation of the output end of the second motor (23). The first screw rod (24) is driven to move the first nut (25) on the surface of the first screw rod (24), and the movement of the first nut (25) drives the connecting seat (9) to move. When the first screw rod (24) rotates forward, the first nut (25) moves downward on the surface of the first screw rod (24), and the connecting seat (9) is driven to move downward by the downward movement of the first nut (25). The projector body (7) is driven to move downward by the movement of the connecting seat (9). When the first nut (25) moves to the bottom of the first screw rod (24), the second motor (23) can be turned off. At this time, the projector body (7) is extended from the installation box (1), and then projection teaching can be carried out; S2. When it is necessary to adjust the position of the projector body (7), the output end of the third motor (30) is started to rotate, and the second screw rod (31) is driven to rotate by the rotation of the output end of the third motor (30), and the second nut (32) is driven to move on the surface of the second screw rod (31) by the rotation of the second screw rod (31), and the fixed block (33) is driven to move by the movement of the second nut (32), thereby driving the sliding sleeve (29) and the installation box (1) to move by the movement of the fixed block (33), so as to facilitate the movement of the projector body (7), and the left and right position of the projector body (7) is controlled by adjusting the forward and reverse rotation of the second screw rod (31), thereby optimizing the convenience of its projection teaching; S3. When it is necessary to clean the dust on the lens of the projector body (7), the output end of the first motor (16) is started to rotate, and the output end of the first motor (16) drives the rotating wheel (17) to rotate. Since the output end of the first motor (16) is located at the eccentric position of the rotating wheel (17), the rotation of the output end of the first motor (16) drives the rotating wheel (17) to make an eccentric movement, and the push plate (15) is intermittently pushed to move to the left through the eccentric movement of the rotating wheel (17). The movement of the push plate (15) pushes the mounting plate (12) and the cleaning brush (14) to move to the left, and the movement of the push plate (15) The spring (19) is compressed by the first motor (16). When the push plate (15) is not pushed to move by the first motor (16), the spring (19) is reset by its own elastic action, thereby pushing the push plate (15) to move to the right. The eccentric movement of the rotating wheel (17) cooperates with the elastic action of the spring (19) to facilitate the reciprocating movement of the push plate (15). The reciprocating movement of the push plate (15) drives the mounting plate (12) and the cleaning brush (14) to reciprocate. The reciprocating movement of the cleaning brush (14) facilitates the cleaning of dust on the lens of the projector body (7), thereby preventing dust from interfering with the projection teaching of the projector body (7).
