Description

3D printing operation platform material return mechanism

technical field

The invention relates to a 3D printing device, in particular to a material return mechanism of a 3D printing operation platform.

Background technique

3D printing (3D printing) is a technology that can print three-dimensional objects (products), using additive manufacturing (Additive Manufacturing, AM) (also known as incremental manufacturing, this manual is called 3D printing according to the popular name), that is, continuous Materials are added and items are formed into layers under computer control. Has been widely used in the industry.

3D printing usually uses a 3D printer, and the injection head set by the 3D printer is used to carry out incremental injection on a work platform. When the product is removed after the operation is completed, it is often because the product is slightly different from the work platform. Therefore, due to the deviation of the operator's direction or the inaccuracy of the accuracy when removing and unloading, the working platform is often slightly shifted, which makes the accuracy of the next product deviate.

In fact, many 3D printing jobs must rely on the presence of operators, and the printed parts must be manually unloaded after printing; Serious design flaws will appear, and the platform may have to be corrected again before the next print. That is to say, it is possible to cause errors in the correction offset when unloading the print.

Furthermore, many 3D printing jobs currently rely on the presence of the operator, and the length of the printed part varies (2 to 72 hours are possible), and the personnel are either waiting on the spot or recording the completion time, and then come back to pick up the part after the printing is completed. And do the pre-work for the next print. This process is not automated, and it also reduces the utilization rate of the machine a lot.

Contents of the invention

In view of the deficiencies of the prior art, the purpose of the present invention is to provide a 3D printing operation platform material return mechanism to solve the above-mentioned technical problems existing in the existing structure.

In order to achieve the above object, the technical scheme adopted in the present invention is:

A 3D printing operation platform material return mechanism, comprising a 3D printer body and an operation platform, characterized in that: the operation platform is constructed under the spray head of the 3D printer body, and the operation platform is provided with an upper plate, the upper plate There are multiple perforations, and the outer frame of the working platform is wrapped with a circular hollow conveyor belt. A push piece is set up on the hollow part of the conveyor belt. The push piece goes around with the conveyor belt and moves horizontally along the top of the upper plate. , and the interior of the work platform is provided with a plurality of telescopic columns corresponding to the plurality of perforations.

The material return mechanism of the 3D printing work platform, wherein: the plurality of perforations of the upper plate sequentially form an array of multiple rows along the conveyor belt circulation path, and the plurality of telescopic columns corresponding to the plurality of perforations are connected to a power element, and the power element Provide the plurality of telescopic columns to gradually expand and contract according to each row.

The material return mechanism of the 3D printing operation platform, wherein: a scraper is also set up on the hollow part of the conveyor belt.

In the material return mechanism of the 3D printing operation platform, a brush piece is also set up on the hollow part of the conveyor belt.

Compared with the prior art, the present invention has the beneficial effects that: the expansion and contraction of the telescopic column can cause damage to the sticking of the product to the work platform, which is beneficial for the pushing piece to move along the conveyor belt when it circles around. It is easier and more convenient to push the product laterally above the upper plate. And because the expansion and contraction of the up and down type of the telescopic column (the up and down direction is defined as the Z axis), the horizontal direction of the work platform (defined as the X and Y axes in the horizontal direction) will not change, reducing or avoiding the operation. The deviation of the X-axis or Y-axis of the platform to reduce or avoid another correction before the next printing.

detailed description

The structure, features and embodiments of the present invention are described below with the aid of drawings, so that examiners can have a better understanding of the present invention.

Please refer to FIG. 1 , the present invention relates to a 3D printing operation platform ejection mechanism, which includes a 3D printer main body 2, and includes a work platform 1, and the operation platform 1 is built on the injection head 21 of the 3D printer main body 2 below.

Please refer to Fig. 2, the work platform 1 is provided with an upper plate 11, the upper plate 11 is provided with a plurality of perforations 111, the outer frame edge of the work platform 11 is wrapped with a circular hollow conveyor belt 12, and the conveyor belt 12 is hollowed out. A push piece 121 is erected at the position, and the push piece 121 can be suspended above the upper board 11 to maintain a gap, or lightly touch the upper board 11 . That is, utilize two symmetrical sides of the conveyer belt 12 to respectively establish two rollers 121A, 121B, respectively surround a belt body 122, and form a hollow with the gap between the two belt bodies 122, and form a hollow between the two belt bodies 122. The push piece 121 is straddled. Therefore, the pushing piece 121 can move laterally along the top of the upper plate 11 when the conveyor belt 12 circulates.

Please refer to FIG. 2 , the working platform 1 is provided with a plurality of telescopic columns 14 corresponding to the plurality of through holes 111 .

Please refer to FIG. 3, the plurality of perforations 111 of the upper plate 11 sequentially form a plurality of row arrays along the circular path of the conveyor belt 12, and the plurality of telescopic columns 14 corresponding to the plurality of perforations 111 are connected to a power element (not shown). , the dynamic element provides that the plurality of telescopic columns 14 expand and contract gradually according to each row or expand and contract according to the settings of the dynamic element.

See also shown in Fig. 4, Fig. 5, Fig. 4 is the state that number telescopic column 14 has not stretched out yet.
