Description

Technical Field

[0001] The present invention relates to the technical field of three-dimensional printers, and in particular to an object reversing device and a reversing method for a three-dimensional printer. Background Art

[0002] 3D printing, a form of rapid prototyping technology, also known as additive manufacturing, is a technique that uses digital model files as a foundation and uses adhesive materials such as powdered metal or plastic to construct objects layer by layer. 3D printing is typically achieved using digital material printers. It is often used to create models in fields such as mold making and industrial design, and has gradually been used for the direct manufacture of some products. Parts printed using this technology already exist. This technology has applications in jewelry, footwear, industrial design, architecture, engineering, and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms, and other fields.

[0003] After printing an object on an existing 3D printer, the object is usually located under the print head. After the object has been stationary for a period of time, it needs to be manually picked up before a new round of printing can be performed. During this process, since the object is located under the print head, when manually picking it up, both the human hand and the printed object are likely to touch the print head, causing damage. Traditional 3D printers do not have automatic reversing and material storage functions, and are unable to turn the printed object to the material storage area for static placement. To this end, the present invention provides an object reversing device and a reversing method for a 3D printer. Summary of the Invention

[0018] Preferably, a reversing method for an object reversing device of a 3D printer comprises the following steps:

[0019] Step 1: After printing the object, the fourth motor drives the transmission shaft and the rotating table to rotate, aligning the idle second electric telescopic rod with the slot on the object printing table through rotation. The object printing table is moved backward to the rear end of the ball screw, and the second electric telescopic rod is extended forward so that the telescopic end of the second electric telescopic rod is inserted into the slot.

[0020] Step 2: After the telescopic end is inserted, the multiple third electric telescopic rods at the combined mounting piece extend outward, so that the telescopic ends of the third electric telescopic rods are inserted into the side slots of the combined mounting block, thereby achieving the effect of combining and fixing the two;

[0021] Step 3: The electromagnet is then de-energized and demagnetized, and the second electric telescopic rod retracts outward, driving the object printing table to move. During the movement, the rotating table rotates and reverses the direction, so that the printed object and the object printing table are moved to the mounting table together.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention utilizes a fourth motor to drive the transmission shaft and the rotating table to rotate. This rotation aligns the idle second electric telescopic rod with the slot on the object printing table. The object printing table is moved backward to the rearmost end of the ball screw. The second electric telescopic rod is then extended forward, and the telescopic end of the second electric telescopic rod is inserted into the slot.

[0024] After the telescopic end is inserted, the multiple third electric telescopic rods at the combined mounting piece extend outward, so that the telescopic end of the third electric telescopic rod is inserted into the side slot of the combined mounting block, thereby achieving the effect of fixing the two together. After that, the electromagnet is powered off and demagnetized, and the second electric telescopic rod retracts outward, driving the object printing table to move, and rotating and reversing through the rotating table during movement, so that the printed object and the object printing table are moved to the mounting table together.

[0025] At the same time, the idle object printing table on the remaining second electric telescopic rod is rotated to the mounting seat, and the idle object printing table is moved and placed on the movable adjustment table by telescopic movement and electromagnetic attraction; through the above structure, the device can have a reversing function. After the object is reversed and moved, the device can perform the next three-dimensional printing operation, thereby improving the three-dimensional printing efficiency, and the subsequent picking process is safer and it is not easy to touch the components of the three-dimensional printer.

[0026] 2. The first electric telescopic rod drives the baffle to move downward, so that the baffle is inserted into the groove, dividing the outer shell into two cavities. The front is used for 3D printing operations, and the rear is used to place printed products and cool the printed products. The cooling fan is used to cool the objects placed in the rear cavity. After cooling, the user can take out the printed objects inside through the rear cover. The above structure can divide the device into two cavities, making it more convenient for users to take it, and the cooling process will not affect the printing operation, which is convenient for users to use.
