Limit switches are arranged at four corners of the platform frame to avoid damage to the all-in-one machine caused by emergency.

The transmission mechanism is a part which is composed of 2 stepping motors, 2 synchronous belts 36, 8H-shaped idle wheels 12, 2 linear guide rails 26, a linear guide rail sliding block 29,2 linear polished rods 39,2 linear sliding bearings 9, a linear polished rod mounting block 35, a fixing bolt and the like and can control the laser engraving and drawing instrument part to move in a plane.

2 stepping motors (a stepping motor I25 and a stepping motor II 41) are fixed on a motor connecting piece on a working bottom plate 40 through a motor positioning block 31, an X-axis motor mounting plate 3 and a Y-axis motor mounting plate 24, the two stepping motors are respectively arranged at the head end and the tail end of any one aluminum alloy section square tube 4, an idler wheel I501 is arranged on a rotating shaft of the stepping motor 25I, an idler wheel is arranged on a square tube supporting frame 14 of the opposite aluminum alloy section square tube 4, the idler wheel II 502 is arranged on the upper side, the idler wheel III 503 is arranged on the lower side, an idler wheel IV 504 is also arranged on a rotating shaft of the other stepping motor II 41, the idler wheel is arranged on the square tube supporting frame 14 of the aluminum alloy section square tube 4 opposite to the rotating shaft, an idler wheel V505 is arranged on the upper side, an idler wheel VI 506 is arranged on the lower side, two pen lifting mechanisms 60 are respectively arranged on, idler wheels are mounted on the two pen lifting mechanisms 60, the left side of each pen lifting mechanism is an upper idler wheel VII 507, the left side of each pen lifting mechanism is an idler wheel VIII 508 on the lower side of each pen lifting mechanism, and the right side of each pen lifting mechanism is an upper idler wheel IX 509 and a lower idler wheel X5010.

The idle wheel I501, the idle wheel II 502, the idle wheel V505, the idle wheel VII 507 and the idle wheel IX 509 are encircled together through one synchronous belt I701, power is provided by one stepping motor I25, and the idle wheel IV 504, the idle wheel VI 506, the idle wheel III 503, the idle wheel VIII 508 and the idle wheel X5010 are encircled on the other synchronous belt II 702 and power is provided by the other synchronous motor II 41. And hold-in range I701, hold-in range 702 all install on the integration mounting bracket, when synchronous machine I25, synchronous machine II 41 syntropy rotated (clockwise or anticlockwise), integration mounting bracket 38 moved left or right (the axial motion of X), when synchronous machine I25, synchronous machine II 41 antiport (the opposite direction), the axial vector of X offsets, the motion of Y axle is realized to the integration mounting bracket.

As shown in fig. 10, the motor rotates to drive the idler (idler i 501, idler ii 504) installed on the rotation shaft to rotate, the synchronous belt (synchronous belt i 701, synchronous belt ii 702) (two synchronous belts one on top of the other) and the idler (idler i 501, idler ii 504) are matched and driven to be connected with one end of the integrated mounting frame 38 connected to the tail end of the synchronous belt (synchronous belt i 701, synchronous belt ii 702), and the other end can drive the synchronous belt (synchronous belt i 701, synchronous belt ii 702) to move.

When moving in the X-axis direction, the two stepper motors are moved to the left (clockwise to left) or right (counterclockwise to right) by simultaneously rotating clockwise or counterclockwise (remembering that both motors are rotating in one direction at the same time).

The stepping motor I25 rotates clockwise to drive the synchronous belt I701 on the upper portion to move, and under the action of the idler I501, the idler II 502, the idler V505, the idler IX 509 and the idler VII 507, a section a of the synchronous belt I701 faces upwards, a section b faces rightwards, a section c faces downwards, a section d faces leftwards and a section e faces downwards. Note that there is a force on each segment of the timing belt i 701 at this time.

The clockwise rotation of the stepping motor II 41 tends to move the lower part of the synchronous belt II 702, and the section A of the synchronous belt II 702 is downward, the section E is upward, the section D is leftward, the section C is upward and the section B is rightward, wherein the section A is the idle pulley IV 504, the idle pulley VI 506, the idle pulley III 503, the idle pulley VIII 508 and the idle pulley X5010.

In the same way, the synchronous motor I25 and the synchronous motor II 41 both rotate anticlockwise, and the integrated mounting frame realizes negative movement towards the X axis.

The two motors must simultaneously rotate in opposite directions, clockwise or counterclockwise, as the entire drawing structure moves in the Y-axis direction.

When the synchronous motor I25 rotates clockwise, the movement direction of the last synchronous belt I701 is the X-axis negative direction, and when the synchronous motor II 41 rotates anticlockwise, the movement direction of the last synchronous belt II 702 is the X-axis positive direction.

When the rotation directions of the two motors are different, the force in the Y-axis direction on segment D, d is the same, and the force in the X-axis direction on segment C, c is opposite and offset in a vector, so that the movement in the Y-axis is completed.

At this time, the motions in the X-axis direction are mutually cancelled in the vector calculation, but the motion directions of the upper and lower synchronous belts in the Y-axis direction are both positive Y-axis directions, so that the integrated mounting block moves in the positive Y-axis direction. And in the same reason, when the left motor rotates anticlockwise, the right motor rotates clockwise to complete the motion in the Y-axis negative direction. By the calculation formula: Δ X ═ Δ a +/Δ B)/2, Δ Y ═ Δ a- Δ B)/2; Δ a ═ Δ X +. Δ Y, Δ B ═ Δ X- Δ Y. Programming is carried out to control the movement of the device on the plane.

The idler is an H-idler 12.

The synchronous motor rotates to drive the idle wheel installed on the rotating shaft to rotate, and the kinetic energy of the motor is transmitted to the synchronous belt through the meshing of the synchronous belt and the idle wheel. The 8 idle wheels change the direction of the transmission power of the synchronous belt, 4 idle wheels change the direction of the idle wheels for 4 times to change the direction of the whole transmission direction at four positions on a plane, determine the transmission area of work and ensure that the work can finally return to the idle wheels, and simultaneously, the work is consistent with the rotation direction of the motor.

The linear guide rail 26 greatly improves the transmission precision and the stability of the integrated machine, the linear guide rail is installed on the aluminum alloy section square tube 4 to move in the X direction, and the linear polished rod 39 completes the motion in the Y direction.

The synchronous belt and the integrated mounting frame 38 are fixedly clamped together so that the synchronous belt can move along the XY axis of the plane along with the increase and decrease of the vector of the synchronous belt.

The integrated mounting frame 38 is mounted on the linear polished rod 39 through the linear bearing 9, and the pen lifting mechanism is mounted on the linear guide rail 26 through the linear guide rail slider 29.

The laser engraving part comprises a laser engraving module 16, and the laser engraving module 16 is installed on the laser engraving module positioning plate 8 and then installed on the integrated installation frame 38.

The positioning block 21 and the integrated mounting frame 38 are fixed together by bolting. The light spring 28 is sleeved on the carbon rod 5, so that the drawing pen 6 and the drawing material are tightly attached together under the action of elasticity, and the pen-dropping effect is realized when the steering engine 19 does not rotate. The steering engine 19 acts on the upper end of the pen clamping seat 22 through the steering engine connecting sheet 20 to enable the whole plotter structure to be lifted up to realize the action of lifting the pen.

When the laser engraving and drawing instrument machine works, the engraved or drawn material is placed on the workbench, the two stepping motors are controlled by the single chip microcomputer to rotate to drive the connected idler and the synchronous belt to be meshed for transmission, and the direction of force transmission is changed through the idler, so that the synchronous belt is driven by an increment in a certain direction to move in a plane together with the integrated mounting part connected with the synchronous belt. The laser engraving module is controlled to work or the steering engine is controlled to realize the actions of pen lifting and pen dropping according to the G code input by the computer to carry out laser engraving and graphic drawing, and when the mounting part moves out of the range, the mounting part touches the limit switch to stop working. The motor reciprocates on the plane according to the signal of the input G code to draw the same pattern as the requirement of the user.

The working mode of the invention is as follows:

the motor rotates the drive and installs the idler (idler I501, idler II 504) rotation in the axis of rotation, and hold-in range (hold-in range I701, hold-in range II 702) and idler (idler I501, idler II 504) cooperation drive are connected in the one end of the terminal integration mounting bracket 38 of hold-in range (hold-in range I701, hold-in range II 702), and one end can drive hold-in range (hold-in range I701, hold-in range II 702) motion in addition. When the synchronous belt moves in the X-axis direction, the two stepping motors rotate clockwise or anticlockwise simultaneously to enable the two stepping motors to move leftwards or rightwards, the stepping motor I25 rotates clockwise to drive the synchronous belt I702 on the upper portion to move, the moving direction of the synchronous belt II 702 is changed from the Y-axis positive direction to the X-axis positive direction under the action of the idler pulley VI 506, the moving direction of the synchronous belt II 702 is changed into the Y-axis negative direction under the action of the idler pulley III 503, and the moving direction of the synchronous belt II 702 is changed into the X-axis negative direction to be connected to the integrated mounting frame 38 under the action of the idler pulley.

And in the same reason, when the left motor rotates anticlockwise, the right motor rotates clockwise to complete the motion in the Y-axis negative direction.
