3D printer printing platform automatic change mechanism

The novel system is related to a 3D printing machine, in particular to an automatic changing mechanism of a printing platform with an automatic turning function, which is convenient for an operator to take a listed 3D object.

Press, 3D printing principle is the 3D version of the printer we are currently using. It will stack the printed paper layers, which will have a three-dimensional shape. If you replace the current printer ink with the spray, you can Harden the fixed material, and then move the nozzle from the original 2D movement (the left and right movement of the inkjet head is regarded as the X axis, the paper feed is regarded as the Y axis), and the 3D movement (the Z axis of the height of the inkjet head) is changed. The basic principle of the current 3D printing machine.

3D printing is to first print the 3D object that you want to print in the computer, and then send it to the slice software to output G-code (the language used in industrial manufacturing, including the parameters that control the movement of the machine or related instructions). G-code can control the 3D printer to print the drawn object. After the 3D printer receives the G-code, it will draw the material spouted out by the nozzle into a plane, and then stack the planes one by one. , can form a 3D finished product.

Please refer to FIG. 1 , which is a commercially available 3D printing machine. The 3D printing machine mainly has a machine 1 , and the machine 1 is provided with a nozzle 2 and a chassis 3 , and the chassis 3 is provided on the chassis 3 . A platform 4 is fixedly disposed on the platform to cooperate with the nozzle 2 to produce a 3D object. However, the disadvantage is that the platform 4 is fixed, so the operator must make a 3D object every time. The 3D component is manually taken, and this way of manually taking the 3D component wastes the operator a lot of time when it encounters a large amount of production.

Therefore, how to improve the shortcomings of the current 3D printing machine that requires a lot of time for the operator to manually take the 3D object is the primary research and development topic of the new type.

In order to understand the technical features, contents and advantages of the present invention and the effects thereof, the present invention will be described in detail with reference to the accompanying drawings, and the drawings used therein, The subject matter is only for the purpose of illustration and supplementary instructions. It is not necessarily the true proportion and precise configuration after the implementation of the new model. Therefore, the scope of the attached drawings and the configuration relationship should not be interpreted and limited. First described.

Referring to Figures 2 and 3, the present invention provides a printing platform automatic changing mechanism for a 3D printing machine, comprising: a printing platform automatic changing mechanism 10, a transmission mechanism 20 and a printing platform 30; the printing platform The automatic change mechanism 10 includes a frame 11 having a drive end 12, a transport end 13 and a connecting portion 14; wherein the drive end 12 is laterally disposed with a blade portion 120, and the horizontal end of the transport end 13 A support plate 130 is disposed and pivotally connected to the shaft 131 in a lateral direction; the transmission mechanism 20 is disposed on the transmission end 12, and includes: a main shaft 21, the main shaft 21 is pivotally connected to the transmission in a lateral manner. The end portion 12 is adjacent to the upper portion of the blade portion 120, and the main rotating shaft 21 is coupled to a transmission portion 22 (which may be a belt design), and the transmission portion 22 is coupled to a transmission unit 23 (which may be a motor design), wherein the The main rotating shaft 21 and the auxiliary rotating shaft 131 are at the same level; The printing platform 30 is coupled to the main rotating shaft 21, the auxiliary rotating shaft 131 and the supporting plate 130 to be coupled to the printing platform automatic changing mechanism 10. When the driving unit 23 is actuated, the driving portion 22 is driven to rotate. The transmission portion 22 drives the main rotating shaft 21 to rotate, and the main rotating shaft 21 drives the printing platform 30 to automatically rotate.

Accordingly, the printing plate 130 is covered by the printing plate 130 and is closely attached to the upper surface, so that the printing platform 30 can have a supporting effect and is driven by the transmission unit 23 of the transmission mechanism 20 to The driving portion 22 drives the main rotating shaft 21 to rotate, and since the printing platform 30 is wound around the main rotating shaft 21 and the auxiliary rotating shaft 131, the printing platform 30 can be relatively rotated when the main rotating shaft 21 rotates, and the printing platform 30 can rotate relative to each other. The sub-rotation shaft 131 provides an auxiliary rotation for rotating the printing platform 30, so that the printing platform 30 can be rotated more smoothly.

Referring to FIGS. 4 and 5, the automatic replacement mechanism 10 coupled to the printing platform is connected to the chassis 41 of a 3D printing machine 40 by the connecting portion 14 of the frame 11, the 3D printing machine. The stage 40 has a head 42 that cooperates with the head 42 to form a 3D object 50 on the printing platform 30. To enable the 3D object 50 to have a positioning effect, the head 42 is sprayed, usually on the surface of the printing platform 30. Applying a layer of adhesive to the bottom of the 3D object 50, but how to make the 3D object 50 has been stated in the prior art, and this part is not a technical feature of the present application, so the author is no longer allowed to Narration.

The technical feature of the present invention is that after the 3D object 50 is fabricated on the printing platform 30, the printing platform 20 can be automatically rotated through the conveyor 20 to move the 3D object 50 to the driving end of the platform conveying mechanism 10. 12 position shifting, when the 3D object 50 is moved to the driving end 12, the knife portion 120 under the driving end 12 can remove the adhesive at the bottom of the 3D object 50 for the operator to take; thereby the operator does not have to The 3D object 50 is manually taken one by one, and the 3D object 50 is moved to the position of the driving end 12 by the driving of the printing platform 30, and the cutting portion 120 is used to remove the 3D object 50. The 3D object 50 can be removed by the adhesive at the bottom of the 3D object 50.

Moreover, the printing platform 30 having the automatic turning function is connected by the printing platform automatic changing mechanism 10, and when the original printing plane of the printing platform 30 is uneven and messy due to the 3D object 50, it is not necessary to re Replacing the new printing platform 30, the production plane of the printing platform 30 that has not been used is automatically rotated under the nozzle 42 to recreate another 3D object 50 on the production plane, so the printing platform automatically The replacement mechanism has the effect of automatically changing the production plane.

It should be noted that the knife portion 120 can not only serve as an adhesive for erasing the bottom of the 3D object 50. When the printing platform 30 is finished with a large amount of the 3D object 50, a part of the adhesive usually remains on the surface. When the portion of the adhesive is rotated through the printing platform 30 to the blade portion 120, the blade portion 120 is used for erasing.
