Description

Probe structure of 3D printer head

Technical Field

The utility model relates to a probe structure of 3D printer aircraft nose.

Background

The relative distance between the printing nozzle and the platform of the 3D printer is a key factor of the combination degree of the bottom and the plane of the printing model. In order to achieve an ideal printing effect, the level of a platform needs to be adjusted before printing, a leveling method of a multi-point confirmation plane is adopted in the prior art, and a physical leveling mode is abandoned. At present, micro switches are arranged at three points of a platform, and a printing nozzle moves to the positions of the micro switches respectively to trigger the micro switches so as to establish a three-dimensional coordinate. However, such leveling requires a plurality of micro switches and is disposed on the printing platform, and the leveling accuracy is not high.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art not enough, provide a probe structure of 3D printer aircraft nose.

The utility model provides a technical scheme that its technical problem adopted is:

the utility model provides a probe structure of 3D printer head, its installs on the printer head of 3D printer, and it includes control circuit, electromagnet coil, magnet, probe and hall sensor, magnet fixed mounting be in on the probe, the control circuit coupling the electromagnet coil is with the drive magnet stretches out and the withdrawal, hall sensor response the motion of magnet, hall sensor signal connection control circuit.

In another preferred embodiment, the sensor further comprises a fixed seat, the electromagnet coil is sleeved on the fixed seat, the magnet and the probe are slidably connected in the fixed seat, and the hall sensor is mounted on the fixed seat.

In another preferred embodiment, the fixing seat is provided with a limit screw for limiting the retraction stroke of the magnet and the probe.

The utility model has the advantages that the probe can extend out and retract due to the adoption of the installation of the probe on the printer head, and the printing function of the printer head is not affected; the probe is pushed by the electromagnet coil and the electromagnet, the structure is simple and efficient, the Hall sensor senses the touch between the probe and the platform and transmits signals to the control circuit, and therefore the basis for the control circuit to establish three-dimensional coordinates is provided. And a limiting screw is adopted for limiting and is adjustable.

The present invention will be described in further detail with reference to the accompanying drawings and examples; however, the utility model discloses a probe structure of 3D printer aircraft nose is not limited to the embodiment.

Detailed Description

An embodiment, as shown in fig. 1, the utility model discloses a probe structure 1 of 3D printer head, it is installed on the printer head 2 of 3D printer, see fig. 2, fig. 3 and fig. 4, probe structure 1 includes control circuit, fixing base 3, electromagnet coil 4, magnet 5, probe 6 and hall sensor 7, magnet 5 fixed mounting be in on the probe 6, magnet 5 with probe 6 slidable connection is in the fixing base 3, electromagnet coil 4 cup joints on the fixing base 3, control circuit couples electromagnet coil 4 is with the drive magnet 5 stretches out and retracts, hall sensor 7 is installed on the fixing base 3 with the response the motion of magnet 5, hall sensor 7 signal connection control circuit. In this embodiment, the fixing base 3 is further provided with a limit screw 8 for limiting the retraction stroke of the magnet 5 and the probe 6.

The embodiment is applied to the leveling working process of the 3D printer as follows:

1. when receiving a detection command from the printer, the control circuit drives the electromagnet coil 4 to push out the probe 6.

2. At the moment, the printer Z moves downwards slowly, when the probe 6 is compressed to a specified distance after contacting a heating plate (printing platform), the control circuit retracts the probe 6 and sends a position signal to the printer, and the printer stops the movement of the Z axis at the moment.

3. By using the principle, a plurality of points of the platform are detected in sequence, and then a plane is formed according to operation.

The above embodiments are only used to further explain the probe structure of the 3D printer head of the present invention, but the present invention is not limited to the embodiments, and any simple modification, equivalent change and modification made by the technical entity of the present invention to the above embodiments all fall into the protection scope of the technical solution of the present invention.
