Embodiment 1

[0040]The method and device for adjusting the light intensity of the light-curing 3D printer screen provided by the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0041] The present invention provides a device for adjusting the light intensity of the screen of a light-curing 3D printer, which is used to adjust the light intensity of the screen of the light-curing 3D printer, such as figure 1 As shown, the device for adjusting the light intensity of the light-curing 3D printer screen includes a light-intensity detection module, which is connected to the light-cure 3D printer. screen image processing.

[0042] Preferably, the light intensity detection module includes a black-and-white camera 1 and a processing module. The black-and-white camera 1 is connected to the Z-axis column of the photocuring 3D printer and the black-and-white camera 1 is set toward the screen. The black-and-white camera 1 is used t...

Embodiment 2

[0051] This embodiment provides a method for adjusting the light intensity of a light-curing 3D printer screen. The light-curing 3D printer screen light intensity adjustment device provided in Embodiment 1 utilizes the light-curing 3D printer screen light intensity adjustment method to adjust the light intensity of the light-curing 3D printer screen. Light intensity is adjusted.

[0052] Such as Figure 4 As shown, the light-curing 3D printer screen light intensity adjustment method includes the following steps:

[0053] S0. Install the light intensity detection module on the photocuring 3D printer.

[0054] First, install the light intensity detection module on the cantilever 4, adjust the horizontal adjustment screws on both sides of the camera bracket 11, so that it can capture the entire forming range of the screen, and adjust the lens focal length of the black and white camera 1 to make the captured image clear. Then, use the USB data cable to connect the black and whit...

Abstract

The invention relates to the technical field of 3D printers and discloses a photocuring 3D printer screen light intensity adjusting method. The method comprises the following steps of S1, collecting a screen image of a photocuring 3D printer by using a black-white camera; S2, dividing the screen image into a plurality of collecting areas; S3, presetting a standard light intensity range of a screen of the photocuring 3D printer; S4, judging whether the actual light intensity of the collecting areas is within the standard light intensity range or not, if so, performing primary adjustment on the gray value of the collecting areas, and if not, adjusting the gray value of the collecting areas, so that the actual light intensity of the collecting areas after adjustment is within the standard light intensity range, and recording the adjustment value of the gray value; and S5, inputting the adjustment value into the photocuring 3D printer, adjusting the gray scale of the screen by using the adjustment value to form a gray scale picture, and enabling the screen to display the gray scale picture in the printing process. According to the photocuring 3D printer screen light intensity adjusting method, the light intensity uniformity of the screen can be improved, and the printing precision of the photocuring 3D printer can be improved.

Description

technical field [0001] The invention relates to the technical field of 3D printers, in particular to a method and device for adjusting the light intensity of a photocuring 3D printer screen. Background technique [0002] With the promotion and development of LCD light curing 3D printing technology, LCD light curing 3D printers are gradually being used by more and more industries and individuals. More and more applications have put forward higher requirements for the accuracy and stability of LCD light-curing 3D printers. In terms of accuracy, in addition to the resolution of the screen will directly affect the printing accuracy, the uniformity of the light intensity of the light source also has a great impact on the printing accuracy. Due to the difference in the actual luminous power of each lamp bead or some other external factors, the light intensity received in the molding range is not very uniform. Uneven light intensity will reduce the accuracy of the printed model a...
