[0025] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and not to limit the present invention.
[0026] In the present invention, in the case of no explanation to the contrary, the positional words contained in terms such as "up, down, inside, and outside" only represent the position of the term in the normal use state, or understood by those skilled in the art It should not be regarded as a restriction on the term.
[0027] Such as Figure 1-3 As described, the present invention provides a 3D printer with power-off protection. The 3D printer with power-off protection includes: a housing 1, a printing controller, a backup power supply, an external power supply, and a power adapter 5. The printing controller , The backup power supply is arranged inside the housing 1, the printing controller is electrically connected to the external power supply through the power adapter 5, the external power supply, the power adapter 5 and the printing controller Connected in series to form a loop, the backup power supply is connected in parallel to the printing controller, and when the external power supply is powered off, the backup power supply can provide a working voltage for the printing controller.
[0028] According to the above technical solution, the 3D printer with power-off protection provided by the present invention is provided with a backup power supply to prevent power-off conditions, the print controller is configured to control the printing work of the printer, and the print controller uses the The power adapter 5 is electrically connected to the external power source. Under normal working conditions, the external power source provides a stable working voltage for the print controller. When the external power source is out of power, the standby power source is configured to be The print controller provides a working voltage, and the backup power source triggers the activation of the alarm, reminding the staff to take emergency measures. The 3D printer with power-off protection of the present invention overcomes the problem that the 3D printer in the prior art will stop printing when it encounters a power failure during the printing process, and the printer will restart when it is connected to the power source. The 3D printer needs to re-import 3D printing numbers. The file model cannot be connected to the printing before the power failure to continue printing, resulting in a waste of 3D printing materials and a longer printing time; if the external circuit is unstable and frequent startup, it will also reduce the life of the 3D printer.
[0029] In a preferred embodiment of the present invention, the 3D printer with power-off protection further includes: a main controller and a voltage detector, the main controller and the voltage detector, the main controller passes The voltage detector is connected to the external power supply, and the main controller is connected to the printing controller. When the external power supply is powered off, the main controller is configured to control the printing controller to print For parameter preservation, when the voltage detector detects that the external power supply is out of power, the voltage detector detects and sends a signal to the main controller, and the main controller controls the printing controller to perform Save the printing parameters, so as to avoid the loss of printing parameters and the problem that printing cannot continue.
[0030] In a preferred embodiment of the present invention, a camera 6 is further provided inside the housing 1, and a display 4 electrically connected to the camera 6 is provided on the outer side of the housing 1, and the camera 6 can be The printing situation inside the housing 1 is monitored in real time, and the monitored picture is displayed on the display 4, which facilitates the monitoring of the staff, so as to quickly and effectively deal with unexpected problems.
[0031] In a preferred embodiment of the present invention, the camera 6 is arranged on the inner surface of the housing 1 through a sliding seat 7, and the sliding seat 7 can slide in the vertical direction. It can be adjusted manually or controlled by a controller, so that the staff can adjust the position of the camera 6 according to the specific situation, so that the picture taken by the camera 6 is clearer, and the staff can understand the internal printing situation .
[0032] In a preferred embodiment of the present invention, the upper surface portion of the housing 1 is recessed downward to form a storage tank 2, and the edge of the storage tank 2 is hinged with a cover that cooperates with the storage tank 2. The staff can store printing materials and other items in the storage tank 2, which is also convenient for staff to take.
[0033] In a preferred embodiment of the present invention, an indicator light 8 is further provided on the outer surface of the housing 1. The indicator light 8 is connected to the standby power source and is configured to display the working status of the standby power source. When the standby power supply is not working, the indicator light 8 is green. When the external power supply is cut off and the standby power supply is working, the indicator light 8 changes from green to red, thereby reminding the staff of the printer Working status.
[0034] During the 3D printing process, a certain amount of noise pollution is often generated, which is caused by the friction between the printing nozzle and the printing platform. In a preferred embodiment of the present invention, a sound-absorbing layer 9 is provided on the inner side of the housing 1 A plurality of sound-absorbing holes are provided on the inner side of the sound-absorbing layer 9, and the noise generated in the working process is absorbed by the sound-absorbing layer 9 through the sound-absorbing holes, so as to achieve the effect of noise reduction. The interior can be filled with sound-absorbing materials such as sponge.
[0035] The preferred embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details in the above-mentioned embodiments. Within the scope of the technical concept of the present invention, many simple modifications can be made to the technical solutions of the present invention. These simple modifications all belong to the protection scope of the present invention.
[0036] In addition, it should be noted that the various specific technical features described in the above-mentioned specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention is The combination method will not be explained separately.
[0037] In addition, various different embodiments of the present invention can also be combined arbitrarily, as long as they do not violate the idea of the present invention, they should also be regarded as the content disclosed in the present invention.
