SUMMERY OF THE UTILITY MODEL

In order to solve the problems and the defects existing in the prior art, the utility model aims to provide a biological 3D printing device for fast unloading a model, which can fast unload the printed model.

In order to achieve the purpose, the utility model provides a biological 3D printing device for fast unloading a model, which comprises a device body, a carrying platform and an air blowing assembly, wherein the carrying platform is arranged below a printing spray head of the device body, an air outlet of the air blowing assembly is connected with an air inlet of the carrying platform, and an air outlet is arranged on the upper surface of the carrying platform; on arranging objective platform in when the model printing is accomplished, the air blast subassembly lets in the air to objective platform, and the air flows out from the air outlet of objective platform upper surface, makes the bottom of model and objective platform's contact surface form the separation.

Further, the carrying platform is a bendable flat plate.

Further, the bending driving assembly is arranged at the bottom of the loading platform.

Further, the bending driving assembly comprises a sucker and an air cylinder mechanism, the sucker is connected with the bottom of the carrying platform, and the air cylinder mechanism is connected with the bottom of the sucker.

Further, the suction cup is attached to a central region of the bottom of the carrier platform.

Further, still include lifting unit, the objective platform passes through lifting unit and links to each other with the device body.

Further, the air purification device also comprises an air purification assembly which is connected with the air blowing assembly.

Compared with the prior art, the beneficial effects of the utility model include: after the model printing is completed, in order to prevent that the intimate contact from forming the vacuum between model bottom and the cargo platform, be difficult to separate under the effect of atmospheric pressure, the air blast subassembly lets in the air to between the contact surface of cargo platform and model bottom, utilizes the air to make model and cargo platform separation, and what like this can relax unloads the model from the cargo platform, and too hard and lead to the model to damage when avoiding machinery or artifical uninstallation.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The embodiment of the utility model provides a biological 3D printing device of quick uninstallation model, as shown in figure 1, including device body 1, cargo platform 2 and air-blast subassembly 3, cargo platform 2 sets up below the printing shower nozzle of device body 1, and the air outlet of air-blast subassembly 3 links to each other with cargo platform 2's air intake, and cargo platform 2's upper surface is equipped with the air outlet; on placing objective platform 2 in when the model printing is accomplished, air blast subassembly 3 lets in the air to objective platform 2, and the air flows out from the air outlet of 2 upper surfaces of objective platform, makes the bottom of model and objective platform 2's contact surface form the separation.

Adopt above-mentioned structure, the model is printed and is accomplished the back, in order to prevent between model bottom and the cargo platform 2 in close contact with formation vacuum, be difficult to the separation under the effect of atmospheric pressure, air blast subassembly 3 lets in the air between the contact surface of cargo platform 2 and model bottom, utilizes the air to make model and cargo platform 2 separation, like this can be relaxed with the model from carrying platform 2 go up the uninstallation, when avoiding machinery or artifical uninstallation too violently hard and lead to the model to damage.

In this embodiment, the loading platform 2 is a flexible flat plate, and may be a flexible metal plate. Can make cargo platform 2 produce slightly crooked like this, let model bottom and cargo platform 2 produce the clearance, conveniently unload the model from cargo platform 2 afterwards.

In particular, the present embodiment further comprises a bending drive assembly 4, which is arranged at the bottom of the carrier platform 2. Crooked drive assembly 4 applys decurrent effort to loading platform 2 bottoms, makes loading platform 2 produce the micro deformation, lets model bottom and loading platform 2 produce the clearance, conveniently unloads the model from loading platform 2 then.

The bending driving assembly 4 includes a suction cup 41 and a cylinder mechanism 42, the suction cup 41 is connected to the bottom of the loading platform 2, and the cylinder mechanism 42 is connected to the bottom of the suction cup 41. The suction cup 41 is closely connected with the bottom of the object platform 2, and the air cylinder pulls the suction cup 41 downwards to enable the suction cup 41 to generate micro-deformation on the bottom of the object platform 2.

Preferably, the suction cup 41 is attached to the central area of the bottom of the carrier platform 2. This allows the deformation of the carrier platform 2 to be more uniform.

The present embodiment further includes a lifting assembly 5 and an air cleaning assembly 6.

As shown in fig. 2, the loading platform 2 is connected to the apparatus body 1 by a lifting assembly 5. Lifting unit 5 can adjust the height of objective platform 2, makes things convenient for the model to unload from objective platform 2.

The air cleaning assembly 6 is connected to the blower assembly 3. Air purification subassembly 6 purifies the air, then gives air-blast subassembly 3 with the air transmission after purifying, avoids the impurity in the air to cause the pollution to the model.

The specific workflow of this embodiment is as follows:

after printing the completion, cylinder mechanism 42 stimulates sucking disc 41 downwards, and sucking disc 41 produces decurrent effort to the 2 bottoms of cargo platform, makes cargo platform 2 produce little deformation, and air blast subassembly 3 will let in between cargo platform 2 and the model bottom through the air after 6 purifications of air purification subassembly simultaneously, through the height of 5 adjustment cargo platform 2 of lifting unit, gets off the model from the light uninstallation of cargo platform 2 at last.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
