Abstract
The invention relates to a gradually-peeling type passive peeling device for a photocuring 3D printer. The gradually-peeling type passive peeling device comprises a printing head; a resin groove is correspondingly formed in the lower face of the printing head; the lower side of the printing head is in matched connection with an L-shaped printing tray; and the end of one lateral wall of the printing tray is connected to the printing head, and the other lateral wall of the printing tray is of a cantilever structure. Due to the fact that the L-shaped printing tray is additionally arranged on the lower side of the printing head, an original 3D printing device is little modified. The printing tray can enable a curing layer and a resin groove coating to break away in a bent deformation or inclined manner, and original face peeling is changed into line peeling. Due to the fact that an inclined angle ranging from 0 degree to 45 degrees is generated during peeling, the peeling force is effectively reduced. Meanwhile, an upward folded edge is arranged at the end of the cantilever of the printing tray, so that printed products are effectively prevented from being scratched in peeling. Thus, the resin groove coating is protected, the service life of the coating is prolonged, and the accuracy and the quality of the 3D printed products are improved.
Description
Technical field
The present invention relates to 3D printing technique neck, particularly relate to the passive stripping off device of a kind of photocuring 3D printer decoupling.
Background technology
3D printing technique designs a model as source with Computerized three-dimensional, by software hierarchy, utilizes the mode such as laser, hot melt, illumination successively to be piled up by special material to cohere, superpose shaping thus produce entity products.3D printing shaping technology is still in continuous differentiation, and the material used is also varied, and in various molding mode, photocuring processes is comparatively ripe mode.
Photocuring processes, be utilize photosensitive resin by the principle being occurred after UV-irradiation to solidify, it is shaping to carry out material addition.It has, and formed precision is high, surface smoothness good, stock utilization high, is more and more accepted.
In photocuring processes, after each illumination forms cured layer, cured layer all will lift, and for illumination is prepared next time, reserves lower one deck solidification gap.Cured layer is solidifying to form in process, almost gap is not had between its bottom surface and bottom covering of resin storage tank, add the resistance (tension force) of dense thick resin, when cured layer front departs from resin storage tank, its adhesive attraction is sizable, especially when first time illumination forms cured layer, another side and the adhesion of pallet phase of cured layer.If the bond strength that pallet face provides is inadequate, the resin bed causing just being cured (basic unit) cannot all be mentioned by the stiction force together large when pallet is mentioned, and all or part of adhesion, bottom resin storage tank, causes and prints unsuccessfully.
Summary of the invention
The object of the invention is to solve the shortcoming existed in prior art, and the passive stripping off device of a kind of photocuring 3D printer decoupling proposed.
To achieve these goals, present invention employs following technical scheme:
The passive stripping off device of a kind of photocuring 3D printer decoupling, comprise printhead, below described printhead, correspondence arranges resin storage tank, be connected in the downside of described printhead a stripping off device, described stripping off device adopts following structure, it comprises the printing pallet of a L-type, and the end of a sidewall of described printing pallet connects on the print head, and another sidewall is cantilever design; Described stripping off device or adopt following structure, it comprises the fixed head being fixedly connected with and going up on the print head, with the side of hinged peel plate below the side of described fixed head, be flexibly connected the opposite side of described peel plate by resetting means at the opposite side of fixed head.
Preferably, a flanging is provided with in the end of described printing pallet cantilever.
Preferably, described printing pallet is that carbon steel material is made, and it keeps good elasticity in long-term bending uses.
Preferably, when departing between resin-cured layer and resin storage tank coating, described by head mechanism or resin storage tank mechanism, the inclination angle of 0 °-5 ° is produced when departing from.
Preferably, the knuckle of described printing pallet is right angle.
Preferably, comprise one end at described resetting means and be fixed on connecting rod in peel plate, connecting rod is through described fixed head, connecting rod on the upside of fixed head is fixed a block, described connecting rod is also socketed a back-moving spring, described back-moving spring is arranged between fixed head and block, and back-moving spring is in compressive state always.
Preferably, described connecting rod adopts bolt, and described block adopts nut.
The passive stripping of decoupling refers to and cured layer is contacted depart to change into linear contact lay with the face bottom resin storage tank and tear and peel off thus reach the object reducing its breakaway force.
Described printing pallet one end is fixed, when printhead is lifted, due to the adhesion effect between cured layer and resin storage tank base coat, the moment of lifting, the stiff end of pallet first lifts under the drive of printhead, and the free end of pallet produces a rotational deformation around stiff end and delayedly to lift under the effect of viscous force, such free end to stiff end just creates an inclination angle.Because cured layer is bonded on the pallet face that free end and stiff end form, cured layer also just creates an inclination angle.Because this inclination angle produces gradually in pallet deformation process, therefore the adhesion of cured layer and resin storage tank depart from also pallet produce be out of shape progressively formed in realize, the passive stripping process of decoupling of Here it is cured layer.
The invention has the advantages that: this device newly increases the printing pallet that a knuckle is right angle L-type in the downside of printhead, change less to original 3D printing equipment, structure is simple, when printing pallet adopts the mode of bending distortion or inclination that cured layer and resin storage tank coating are departed from, original emaciated face is departed from from changing over line, the inclination angle of one 0 °-45 ° is produced when departing from, print pallet is that carbon steel material is made simultaneously, it keeps good elasticity in long-term bending uses, effectively reduce breakaway force, be provided with a flanging upwards in the end printing pallet cantilever simultaneously, effectively avoid the product that scratch is printed when peeling off, this not only protects resin storage tank coating, improve the service life of coating, and improve precision and the quality of 3D printed product.
