It states to receive to be provided with above R2 and receives R1；
2) light quantity for receiving R1 and reception R2 is transferred to single-chip microcontroller processing, and light quantity intensity is become voltage swing, right respectively
Voltage V1 and V2 are answered, and reference voltage VREF is set；
3) consumptive material is determined whether according to the following method: when not having consumptive material, being received the light quantity that R2 receives and is greater than reception R1, institute
With V2 be greater than V1, while the value of VREF set up be greater than V2, the condition for detecting no material consumption is V2 > V1, while VREF > V2；When having
When opaque consumptive material, R2 is by shield, so V2 < V1, the condition that detecting has opaque consumptive material is V2 < V1, when there is transparent consumptive material
When, the light quantity that R2 receives is greater than R1, and V2 is greater than V1, but the light that R2 receives is concentrated by the lens effect of transparent consumptive material, and light quantity increases,
VREF is caused to be less than V2, the condition that detecting has transparent consumptive material is V2>V1, while VREF<V2；
More specifically, the transmitting T is infrared transmitting tube or the device for emitting other light sources, the reception R1, receives R2
Either emit the corresponding light source adopter of T transmitting for infrared receiving tube；
More specifically, the angle for receiving R1 and receiving between R2 can change according to demand, and preferably 30 ° or 45 °；
The beneficial effects of the present invention are: compared with the prior art, not only can quickly and effectively detect whether opaque consumption
Material, moreover it is possible to detect whether transparent consumptive material, improve the adaptation range of detection.
Detailed description of the invention
Light receiver schematic diagram when Fig. 1 is no material consumption of the present invention；
Fig. 2 is light receiver schematic diagram when the present invention has opaque consumptive material；

Specific embodiment
The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the invention.
As shown in Figure 1-3, a kind of method of 3D printer consumptive material detection, includes the following steps:
1) the transmitting T of transmitting light is respectively set in consumptive material two sides and receives the reception R2 of the light for emitting T, in institute
It states to receive to be provided with above R2 and receives R1；
2) light quantity for receiving R1 and reception R2 is transferred to single-chip microcontroller processing, and light quantity intensity is become voltage swing, right respectively
Voltage V1 and V2 are answered, and reference voltage VREF is set；
3) consumptive material is determined whether according to the following method: when not having consumptive material, being received the light quantity that R2 receives and is greater than reception R1, institute
With V2 be greater than V1, while the value of VREF set up be greater than V2, the condition for detecting no material consumption is V2 > V1, while VREF > V2；When having
When opaque consumptive material, R2 is by shield, so V2 < V1, the condition that detecting has opaque consumptive material is V2 < V1, when there is transparent consumptive material
When, the light quantity that R2 receives is greater than R1, and V2 is greater than V1, but the light that R2 receives is concentrated by the lens effect of transparent consumptive material, and light quantity increases,
VREF is caused to be less than V2, the condition that detecting has transparent consumptive material is V2>V1, while VREF<V2；
More specifically, the transmitting T is infrared transmitting tube or the device for emitting other light sources, the reception R1, receives R2
Either emit the corresponding light source adopter of T transmitting for infrared receiving tube；

Concrete operating principle introduction:
R1 and R2 is the infrared receiving tube of two different angles, and transmitting T is infrared transmitting tube；
The number of arrow, represents the density of light；
The light quantity that namely R1 and R2 receives is different；
R1 is 45 degree, is drawn an analogy, and certain other angles can also be with such as 30 degree；
R2 is the infrared receiver pipe faced directly；
The light of receiving is different, so that it may judge either with or without consumptive material, be transparent consumptive material or opaque consumptive material；
The light quantity that R1 and R2 receives gives single-chip microcontroller processing, the intensity of signal is become voltage swing, single-chip microcontroller collects
The size of voltage, do-it-yourself algorithm compare, and compare the voltage of R1 and R2, whether make a decision is transparent consumptive material；
The specific method is as follows:
Single-chip microcontroller is as follows come contrast judgement specific algorithm by specific algorithm:
By detecting the voltage of two reception pipes of R1R2, it is calculated as V1V2 respectively, while setting up a comparison reference voltage
VREF；
