DETAILED DESCRIPTION

[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] The present invention provides a tracker motor transmission locking mechanism, including a drawing support plate, on which an X-direction transmission mechanism, a Y-direction transmission mechanism and a drawing pen device are arranged, and the X-direction transmission mechanism can drive the Y-direction transmission mechanism to move along the X direction in a horizontal plane. The drawing pen device is arranged on the Y-direction transmission mechanism, and the Y-direction transmission mechanism can drive the drawing pen device to move along the Y direction in a horizontal plane, wherein the X direction and the Y direction are perpendicular to each other. An X-direction locking mechanism is arranged on the X-direction transmission mechanism, and is used to lock the X-direction transmission mechanism. A Y-direction locking mechanism is arranged on the Y-direction transmission mechanism, and is used to lock the Y-direction transmission mechanism. In actual use, when the X-direction transmission mechanism works normally, the X-direction locking mechanism will not lock the X-direction transmission mechanism, and the X-direction transmission mechanism works normally. When the X-direction transmission mechanism stops working, the X-direction locking mechanism locks the X-direction transmission mechanism to prevent the X-direction transmission mechanism from moving. Similarly, when the Y-axis transmission mechanism is working normally, the Y-axis locking mechanism will not lock the Y-axis transmission mechanism. When the Y-axis transmission mechanism stops working, the Y-axis locking mechanism locks the Y-axis transmission mechanism to prevent the Y-axis transmission mechanism from moving, thereby driving the painting pen device to move together, thereby causing the painting pen device to collide with the equipment and be damaged.

[0020] In specific implementation, the X-direction transmission mechanism includes a horizontally arranged double-axis motor 1, on which two motor shafts of the double-axis motor are respectively provided with a driving wheel 1 2, and the two motor shafts can drive the driving wheel 1 to rotate synchronously; and also includes two driven wheels 13, the positions of the two driven wheels 1 respectively correspond to the positions of the two driving wheels 1, and a transmission belt 1 4 is respectively wound between the two driving wheels 1 and the driven wheel 1, and the Y-direction transmission mechanism is installed on the two transmission belts 1. Among them, the double-axis motor, the driving wheel 1, the driven wheel 1 and the locking mechanism are all installed on the drawing support plate through a mounting seat, and when the double-axis motor drives the motor shaft to rotate, it can drive the driving wheel 1 to rotate synchronously, and then drive the driven wheel 1 to rotate together through the transmission belt 1, and finally drive the Y-direction transmission mechanism to move along the X direction in the horizontal plane.

[0021] The X-axis locking mechanism includes a locking wheel 5 and an electromagnetic lock 1 6. The locking wheel is sleeved on one of the motor shafts of the dual-axis motor and is fixedly connected to the motor shaft. A plurality of locking holes 1 7 are distributed around the circumference of the locking wheel. The electromagnetic lock 1 is located on one side of the locking wheel, and its locking pin can be inserted into the locking hole 1 to lock the locking wheel. When the X-axis transmission mechanism stops working, the electromagnetic lock 1 is inserted into the locking hole 1 to lock the locking wheel to prevent the X-axis transmission mechanism from continuing to operate; when the X-axis transmission mechanism is operating normally, the electromagnetic lock 1 will not lock it.

[0022] The Y-direction transmission mechanism includes two bases 8, which are respectively located on two transmission belts I and fixedly connected to the transmission belts I; a single-axis motor 9 is horizontally arranged on one of the bases, the motor shaft of which is perpendicular to the axial direction of the motor shaft of the dual-axis motor, and a driving wheel II 10 is sleeved on the motor shaft of the single-axis motor. A driven wheel II 11 is arranged at the position corresponding to the driving wheel II on the other base, a transmission belt II 12 is wound between the driving wheel II and the driven wheel II, and the painting pen device 15 is fixedly connected to the transmission belt II. When the single-axis motor drives the motor shaft to rotate, it can drive the driving wheel II to rotate synchronously, and then drive the driven wheel II to rotate together through the transmission belt II, and finally drive the painting pen device to move along the Y direction in the horizontal plane.

[0023] The Y-axis locking mechanism includes an electromagnetic lock II 13. On the driven wheel II, there are multiple locking holes II 14 distributed around it. The axis of the locking hole II is parallel to the axis of the driven wheel II. The electromagnetic lock II is located on one side of the driven wheel II, and its lock pin can be inserted into the locking hole II to lock the driving wheel II. When the Y-axis transmission mechanism stops working, the electromagnetic lock II is inserted into the locking hole II on the driven wheel II to lock the driven wheel II, preventing the Y-axis transmission mechanism from continuing to operate; when the Y-axis transmission mechanism is operating normally, the electromagnetic lock II will not lock it.

[0024] In specific implementation, the electromagnetic lock I and the electromagnetic lock II have the same structure, including a bracket of a rectangular frame structure, a conductive coil is arranged in the bracket, the conductive coil is arranged horizontally, and its two ends are respectively fixedly connected to the two ends of the bracket. An armature shaft is also provided on the bracket in a sliding manner, the axis of the armature shaft coincides with the axis of the conductive coil, and passes through the two ends of the bracket, and a locking pin is formed at one end close to the locking wheel or the driven wheel II. When the conductive coil is energized, the armature shaft moves in a direction away from the locking wheel or the driven wheel II and disengages from the locking wheel or the driven wheel II, so that the electromagnetic lock I and the electromagnetic lock II are not in a locked state, and the locking wheel or the driven wheel II can rotate normally. A reset spring is also provided between the armature shaft and the bracket. When the conductive coil is de-energized, under the action of the reset spring, the lock pin can be inserted into the locking hole I or the locking hole II, thereby achieving locking, and the locking wheel or the driven wheel II stops rotating. A limit block is respectively provided at both ends of the armature shaft, and the limit block is located on the outside of the two ends of the bracket; wherein, the end of the armature shaft away from the locking wheel or the driven wheel II is directly fixedly connected to the limit block, and the end close to the locking wheel or the driven wheel II passes through the limit block and is fixedly connected to the limit block, and the reset spring is located between the limit block and the bracket.

[0025] Working process: When the dual-axis motor is powered on and enters the working state, the lock pin of the electromagnetic lock I withdraws from the lock hole I of the lock wheel, and the X-axis transmission mechanism works normally; when the dual-axis motor is powered off and enters the stop state, the lock pin of the electromagnetic lock I is inserted into the lock hole I of the lock wheel, and the rotating shaft connected to the driving wheel I is fixed to prevent it from rotating, thereby locking the X-axis transmission mechanism. Similarly, when the single-axis motor is powered on and enters the working state, the lock pin of the electromagnetic lock II withdraws from the lock hole II of the driven wheel II, and the Y-axis transmission mechanism works normally; when the single-axis motor is powered off and enters the stop state, the lock pin of the electromagnetic lock II is inserted into the lock hole II of the driven wheel II, and the driven wheel II is locked to prevent it from rotating, thereby locking the Y-axis transmission mechanism.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the technical solution.
