Such as a kind of 3D printing device of Fig. 1-2, including printing mechanism 2, Sheng Ye mechanism 3 and the exposure machine being mounted on pedestal 1 Structure 4, wherein the printing mechanism 2 includes mould group 23, and is slidably mounted on print platform in mould group 23, the print platform Including printing arm 21, and the platform assembly 22 being removably mounted on printing arm 21, the platform assembly 22 and printing arm 21 It is fixed by magnetic part；The Sheng Ye mechanism 3 includes material box base 31, and is removably mounted at material box base Material box 32 on 31, the exposure mechanism 4 are located at 32 lower section of material box, the figure light that the exposure mouth 411 of exposure mechanism 4 projects Source direct projection is reflected into 32 bottom of material box.The pedestal 1 is equipped with control flow 11, the control of the control flow 11 and 3D printing device Molding block is connected, and can specifically use touch screen, human-computer interaction may be implemented by touch screen, print procedure is made to be more convenient intelligence Energy.

In the present embodiment, as shown in fig. 3 to 7, the printing arm 21 includes printing arm body 211, the printing arm body 211 connecting pin 2111 is movably arranged in the mould group 23 of 3D printing device, and the free end 2112 of the printing arm body 211 is set Be magnetic component 212, and the magnetic part 212 includes the first magnet 2121 and the second magnet 2122 setting up and down, and control is opened It closes 2123 to be connected by rotary shaft 2124 with the first magnet 2121, the first magnet 2121 is rotated with control switch 2123 and rotated. In the present embodiment, the specific set-up mode of the magnetic part 212 are as follows:

First magnet 2121 is strong magnet, and the second magnet 2122 is weak magnetic iron.First magnet 2121 and the second magnet 2122 is setting up and down in magnet slot 213, wherein underlying second magnet 2122 is fixedly mounted in magnet slot 213, i.e., Second magnet 2122 will not be rotated with the rotation of control switch 2123.First magnet 2121 is movably arranged on magnet slot In 213, for convenience of the rotation of the first magnet 2121, the first magnet 2121 and the second magnet 2122 can leave and take certain spacing, i.e., The depth of magnet slot 213 is greater than the sum of the thickness of the first magnet 2121 and the second magnet 2122.Magnet slot 213 is close to control switch 2123 sides are fixedly installed with cover board 214, and 214 one side of cover board is for covering the first magnet 2121, bullet when preventing it identical charges repel each other Magnet slot 213 out, on the other hand for controlling the rotational angle of the first magnet 2121.Wherein, cover board 214 controls the first magnet The specific set-up mode of 2121 rotational angle are as follows: the cover board 214 is equipped with counterbore 2141, counterbore close to 2121 side of the first magnet The through-hole 2142 passed through for rotary shaft 2124 is equipped among 2141.The counterbore 2141 is by major diameter segmental arc 2141a and minor diameter Segmental arc 2141b composition；2124 bottom of rotary shaft is equipped with gag lever post 2125, and the both ends of gag lever post 2125 are respectively provided with 1 respectively Connecting column 2125a and 2125b towards the first magnet 2121, the connecting column 2125a and 2125b are individually positioned in the first magnet In 2121 2 connecting holes 2121a and 2121b, the main part of the gag lever post 2125 is mounted on the entire rotary shaft of perforation The groove 2124a of 2124 bottoms, rotates rotary shaft 2124, and gag lever post 2125 drives the first magnet 2121 to rotate therewith.Gag lever post The 2125 connecting column 2125a far from rotary shaft 2124 are less than the radius of major diameter segmental arc 2141a to the distance of rotary shaft 2124, but Greater than the radius of minor diameter segmental arc 2141b, such setting can limit the rotation angle of gag lever post 2125, and then control the One magnet 2121 rotates in the set angle in magnet slot 213, prevents its rotation excessive.For convenience of 2121 turns of the first magnet Dynamic, 2 connecting holes 2121a and 2121b of first magnet 2121 are set for the eccentric, i.e., gag lever post 2125 is non-is arranged first The central area of magnet 2121.

Above-mentioned 212 working principle of magnetic part: when control switch 2123 turns to opening state, setting up and down first Magnet 2121 and 2122 the same end of the second magnet are identical polarity, at this time according to principle of same-sex repulsion, 2121 He of the first magnet Second about 2122 magnet is mutually exclusive, and only the second magnet 2122 can generate magnetism to entire magnetic part 212, i.e. magnetic portion at this time Part 212 is weak magnetic state.When control switch 2123 turns to closed state, the first magnet 2121 setting up and down and the second magnetic 2122 the same end of iron is different polarity, at this time according to principle of opposite sex attraction, the first magnet 2121 and the second about 2122 magnet It attracts each other, the magnetic of entire magnetic part 212 is generated jointly by the first magnet 2121 and the second magnet 2122, at this time magnetic portion Part 212 is strong magnetic state.

As shown in figure 8, the platform assembly 22 includes shell 221, the shell 221 is equipped with free for printing arm body The accommodating chamber 222 that end 2112 is protruded into, the bottom of the accommodating chamber 222 are equipped with magnetic gold corresponding with 2122 bottom of the second magnet Belong to part 223, the magnetic metal part 223 can be iron plate, and being also possible to other has the metalwork that can be attracted.

For the accurate installation for guaranteeing printing arm 21 and platform assembly 22.It prints arm body 211 and is equipped at least three location hole 215, it is equipped in the accommodating chamber 222 and the one-to-one flexibly positioned column of the location hole 215.The positioning column includes point Pearl and elastic component are embedded in positioning bead elasticity in location hole 215 by elastic component.

The U-type groove 225 moved into for rotary shaft 2124 is additionally provided with above the accommodating chamber 222.The platform assembly shell 221 Lower end is equipped with integral structure stamp pad 224.The stamp pad 224 of integral structure keeps printing more convenient, is not in sepage phenomenon.

It is inhaled between the printing arm 21 and platform assembly 22 of 3D printing platform described in the utility model by magnetic part 212 It closes and fixes, facilitate installing and dismounting.When work, the free end 2112 for printing arm body 211 is protruded into the accommodating chamber of platform assembly 22 In 222, by location hole 215 and positioning column, make the two exactitude position.Then, control switch 2123 is rotated, rotary shaft is passed through 2124 polarity for keeping first magnet 2121 different with 2122 the same end of the second magnet, the two attract each other generate it is powerful Suction so that the magnetic metal part 223 positioned at 222 bottom of accommodating chamber be sucked, and then platform assembly 22 is stably installed at and is beaten It prints on arm 21.When needing to remove platform assembly 22 from printing arm 21, by rotating control switch 2123, make the first magnet 2121 and 2122 suction of the second magnet reduce, thus by platform assembly 22 quickly from printing arm 21 on remove.
