Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing, and in particular to a printing platform which is convenient for observing a printed model. Background Art

[0002] 3D printer, also known as three-dimensional printer (3DP), is a kind of additive manufacturing technology, that is, a machine of rapid prototyping technology. On a macro level, 3D printers can be divided into industrial grade and desktop grade. The main difference between industrial grade 3D printers and desktop grade 3D printers lies in the printing accuracy and application range.

[0003] Most desktop 3D printers are based on FDM technology, that is, fused deposition modeling technology to print models. Desktop 3D printers are small in size, light in weight, simple and easy to learn, and can be used to make things of almost any shape. Therefore, in recent years, the use of desktop 3D printers in the field of education has become more and more frequent, and at the same time, it has played a positive role in promoting the field of education. For example, students can print out their own "problems", such as printing a geometric figure, and find answers in their own learning space. This can not only improve the quality of teaching and the teaching ability of teachers, but also subvert the traditional way of education.

[0004] However, since the printing platform size of desktop 3D printers is generally not large, the size of the printed model teaching aids is also relatively small. In addition, the number of students faced in the educational process is relatively large, which is not conducive to students' observation and learning. Each student can only observe the model teaching aids from a local angle, which greatly reduces the educational effect. Utility Model Content

[0040] The main frame 2 is connected to the base 1, the Y-axis transmission mechanism 3 is installed on the base 1, the printing platform 4 is arranged on the Y-axis transmission mechanism 3, the synchronous sliding device 5 is arranged on the base 1, the rotating bearing device 6 is installed on the synchronous sliding device 5, and the rotating bearing device 6 is connected to the bottom of the printing platform 4, and the four groups of auxiliary fill light devices 7 are respectively installed on the four sides of the printing platform 4, wherein

[0041] The rotating bearing device 6 is driven to move linearly upward to carry and lift the printing platform 4. The printing platform that is convenient for observing the printed model can lift the printing platform 4 together with the model teaching aids upward after the printing of the model teaching aids is completed by setting the rotating bearing device 6. At the same time, under the action of the rotating bearing device 6, the printing platform 4 can be rotated, which can not only increase the display height of the model teaching aids, but also adjust the display angle of the model teaching aids, so that students can observe and learn the model teaching aids from different angles, rather than just one-sided observation, thereby improving the educational effect. The synchronous sliding device 5 can make the rotating bearing device 6 move synchronously with the printing platform 4 to ensure that no matter where the printing platform 4 is, the rotating bearing device 6 can carry and lift it, thereby improving the fault tolerance rate. At the same time, the auxiliary fill light device 7 can illuminate the model teaching aids from four directions, so that the light reflected by the model teaching aids becomes stronger, so that students can see more clearly and more conveniently.

[0042] Optionally, the synchronous sliding device 5 includes a rectangular hole 51, a slide bar 52, a slide groove 53 and a concave double-ear plate 54;

[0043] The rectangular hole 51 is opened on the base 1, the two slide bars 52 are installed on the base 1, and the two slide bars 52 are respectively located on both sides of the rectangular hole 51, the two slide grooves 53 are inverted and slidably installed on the two slide bars 52, the two ends of the concave double ear plate 54 are installed on the two slide grooves 53, and the concave double ear plate 54 extends downward to the inside of the base 1, wherein

[0044] Push the concave double-ear plate 54, and the two slide grooves 53 slide on the two slide bars 52. A rotating bearing device 6 connected to the printing platform 4 is installed on the concave double-ear plate 54. When the printing platform 4 moves in the Y direction, under the action of the slide bar 52, the slide groove 53 and the concave double-ear plate 54, the rotating bearing device 6 can move synchronously with the printing platform 4, ensuring that no matter where the printing platform 4 finally stops, the rotating bearing device 6 can carry and lift it, thereby improving the fault tolerance rate. The rectangular hole 51 allows the concave double-ear plate 54 to extend downward to the internal space of the base 1, thereby providing sufficient installation and operation space for the rotating bearing device 6.

[0045] Optionally, the rotating bearing device 6 includes an electric cylinder 61, a ball bearing 62 and an arc-shaped connecting rod 63;

[0046] The electric cylinder 61 is installed on the concave part of the concave double-ear plate 54. The electric cylinder 61 is a modular product that integrates a servo motor and a lead screw. The rotational motion of the servo motor is converted into linear motion, and the position, speed and thrust can be accurately controlled. In particular, in linear motion, the inner ring of the ball bearing 62 is sleeved and installed on the output shaft of the electric cylinder 61. The ball bearing 62 and the output shaft of the electric cylinder 61 are interference fit, that is, the output shaft diameter of the electric cylinder 61 is slightly larger than the inner ring diameter of the ball bearing 62, so that the inner ring of the ball bearing 62 is tightly sleeved on the shaft to form a whole. The four arc-shaped connecting rods 63 are circumferentially installed on the outer side wall of the ball bearing 62, and the four arc-shaped connecting rods 63 are all connected to the bottom surface of the printing platform 4, wherein

[0047] The electric cylinder 61 is driven, and the output shaft of the electric cylinder 61 moves linearly upward, and lifts the printing platform 4, which can increase the display height of the model teaching aids and ensure that students at the back can also observe the model teaching aids. When the lifting is completed, the electric cylinder 61 is stopped, and under the action of the ball bearing 62 and the four arc-shaped connecting rods 63, force can be applied to the printing platform 4 to rotate to adjust the display angle of the model teaching aids, so that students can observe and learn the model teaching aids from different angles, thereby improving the educational effect. The lifting height of the electric cylinder 61 depends on the specific height of the model teaching aids.

[0048] Optionally, the auxiliary fill light device 7 includes a right angle bracket 71 and an LED integrated lamp tube 72;

[0049] The two right-angle brackets 71 are installed on one side surface of the printing platform 4, and the LED integrated lamp tube 72 is installed on the two right-angle brackets 71. The LED integrated lamp tube 72 is an existing lamp that integrates the lamp tube bracket together. It is easy to install and can be used after connecting to the power supply. When students observe the model teaching aids, the LED integrated lamp tube 72 is connected to the power supply to emit light, and the model teaching aids are illuminated from four directions. At the same time, the light reflected by the model teaching aids will become stronger, so that students can see more clearly and it is more convenient for students to observe the model teaching aids.

[0051] A number of the countersunk holes 8 are opened on the printing platform 4 and extend straight downward to the inside of the Y-axis transmission mechanism 3. A number of the bolts 9 are connected to the countersunk holes 8 to fix the printing platform 4 on the Y-axis transmission mechanism 3 to ensure successful printing. A number of bolts 9 are immersed in the countersunk holes 8 to avoid the protrusion of a number of bolts 9 and ensure the flatness of the surface of the printing platform 4. After printing is completed, a number of bolts 9 can be unscrewed to separate the printing platform 4 from the Y-axis transmission mechanism 3, so that the rotating carrier device 6 can lift the printing platform 4.

[0052] Optionally, the material of the right-angle frame 71 includes but is not limited to aerogel felt. The temperature of the FDM 3D printer is very high when it is working, and the thermal conductivity of aerogel felt is very low, which can effectively prevent excessive heat from being transferred to the LED integrated lamp tube 72, prevent the LED integrated lamp tube 72 from aging too quickly, and extend its service life.

For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
