Description
Technical field
The invention belongs to 3D printing manufacturing fields, and in particular to the 3D that hott bed level control is carried out by forced synchronism device is beaten
Print machine.
Background technology
3D printer is divided into FDM technology (fusion sediment), SLA (photocuring), SLS (laser sintered) by molding principle;
The hott bed of FDM 3D printers needs to move up and down along Z-direction in print procedure, is mainly driven using ball-screw rotation
The mode of hott bed movement.Since printer is not of uniform size, there is single screw to the not equal configuration of multifibres thick stick, existing more guide screw movements
It is controlled using pattern of the leading screw with a stepper motor;Large-scale FDM 3D printers, such as JMT800 type FDM 3D
The equipment size of printer is:1600*1200*1630mm, similar large-scale FDM 3D printers, all there are two or two with
On ball-screw.Stepper motor is the critical component of electromechanical integration as executive component, and electric impulse signal is changed by it
The opened loop control member stepper motor part of angular displacement or displacement of the lines.In the case of non-overload, the rotating speed of stepper motor, the position of stopping
The frequency and umber of pulse depending on pulse signal are set, without being influenced by load variation, when step actuator receives an arteries and veins
Signal is rushed, it rotates an angle with regard to Driving Stepping Motor by the direction of authorization, and referred to as " step angle ", its rotation is with fixation
Angle step by step run.Existing more guide screw movements are controlled using pattern of the leading screw with a stepper motor
Mode, stepper motor is uncontrolled device driving under unexpected power-off or equipment emergency stop pattern, i.e., dry by external force
In the case of disturbing, cause two or more stepper motors, moment rotational angle is inconsistent so that between leading screw by
Power uneven the case where causing some leading screw to be declined by gravity, generates, and each leading screw falling head is inconsistent, so as to cause heat
The unbalanced situation of bed occurs.
For FDM 3D types, can start the first layer of printing uniformly be firmly adhered on hott bed, determine
The success or not integrally printed, that is to say, that if first layer can be bonded on hott bed well, if subsequent printing is not
Accidents happened to, so that it may smoothly to complete.But the printing of first layer is not easy so, one of reason is exactly to beat

Effect is often also unreliable, so that the printing effect to refined model is undesirable.Moreover, manual leveling device is only suitable
FDM 3D printers for small volume.In contrast, the size of printing objects is bigger, for FDM 3D printer machines
The requirement of the parameters such as the stability of manufacturing technology, technique and machine all can be higher.In particular, it should be pointed out that for big
For type FDM 3D printers, hott bed moment caused by the case of unexpected power-off is unbalance, more unbalance than caused by operation error
More be difficult to adjust and repair because it involve control system recovery and stepper motor whether have memory function.In reality
In the work of border, hott bed adjustment needs professional to adjust for a long time just to can ensure that its flatness;It can not be ignored, it is existing
Multifibres thick stick independent operating system, hott bed flatness are easy to be destroyed, or even are required for adjusting again after having printed power-off every time
It is whole.
In conclusion FDM 3D printers large-scale at present, equipped with more than two ball-screws, after being influenced by external force
(before being switched on after power-off every time), is required for re-starting leveling to hott bed, could normal operation.
