Description

Technical Field

[0002] With the development of the additive manufacturing industry, more and more three-dimensional models need to be completed by SLA light-curing printers. At the same time, with its own advantages of high precision, rapid prototyping, and multiple degrees of freedom design, SLA light-curing printers have demonstrated their unique advantages in many fields such as profiling manufacturing, medical equipment, and customized parts industries. In practical applications, during the printing process of the SLA light-curing printer, and after the printing job is completed, when the three-dimensional model is removed from the carrier, some semi-solid material will remain on the carrier. At present, most of the above-mentioned semi-solid residual material is still cleaned manually. This operation is not only inefficient and has a low degree of automation, but it is also possible that during the cleaning process, the residual material will fall into the liquid storage tank below along the mesh on the carrier (the conventional carrier is provided with meshes for the photosensitive resin to pass through). Once the residual material falls, it will affect the composition of the photosensitive resin in the liquid storage tank, and the original liquid resin will be converted into a solid-liquid mixed state, which will greatly affect the accuracy of the subsequent prints.

Compared with the prior art, when it is necessary to clean the carrier plate 12, the carrier plate 12 is firstly lifted to the top of the liquid storage tank 11 by the lifting mechanism 101, and then the material taking rod 7 is placed on the edge of one side of the length direction of the carrier plate 12, the softening liquid nozzle 4 is turned on, and the first driving mechanism 301 drives the movable block 3 to move from one end of the liquid storage tank 11 to the other end, so that the softening liquid is evenly sprayed on the upper end surface of the entire carrier plate 12, so that the softening liquid and the residual material remaining on the carrier plate 12 are fully contacted and reacted, and after the softening liquid is sprayed, the softening liquid nozzle 4 is closed, and the coagulant nozzle 5 is turned on, so that the first driving mechanism 301 drives the movable block 3 to move from one end of the liquid storage tank 11 to the other end. The resin curing agent is evenly sprayed on the upper end surface of the entire carrier plate 12, so that the resin curing agent and the residual material body remaining on the carrier plate 12 are fully integrated. After that, the coagulant nozzle 5 is closed, the curing lamp 6 is turned on, and the movable block 3 is driven to move back and forth from one end of the liquid storage tank 11 to the other end through the first driving mechanism 301, so that the resin curing agent sprayed on the carrier stage and the residual material body are fully reacted, and a layer of adhesive film is condensed on the upper end surface of the carrier plate 12. The formed adhesive film is bonded to the pre-placed material picking rod 7, and then the material picking rod 7 is connected to the movable block 3. The movable block 3 drives the material picking rod 7 to move. With the help of the adhesion between the adhesive film and the material picking rod 7, the material picking rod 7 can drive the adhesive film to detach from the carrier plate 12, thereby removing the residual material body on the carrier plate 12. The residual material body cleaning device for an SLA light-curing printer provided by the utility model reduces manual participation and solves the problem of inconvenience in manually cleaning the residual material body.

[0033] In some embodiments, see Figures 1 to 3 The movable block 3 includes a first block 31 and a second block 32. The first block 31 is slidably connected to the first guide rail 201. The softening liquid nozzle 4 and the coagulant nozzle 5 are arranged on the first block 31. A second slide rail and a second driving mechanism 302 are provided on the first block.

[0034] Furthermore, a rotating clamp 303 is provided on the second block 32, and the rotating clamp 303 includes a rotating motor and a chuck 3031 arranged at the rotating end of the rotating motor. In the present embodiment, two symmetrically arranged movable clamp rods 3032 are connected to the chuck 3031, one end of the movable clamp rod 3032 is a hinged end, which is hinged on the chuck 3031, and a torsion spring is provided between the hinged end and the chuck 3031, and the other end of the movable clamp rod 3032 is a clamping end, which is used to clamp the material picking rod 7. In the present embodiment, the elastic force generated by the torsion spring makes the two movable chucks 3031 approach each other, and a slot 71 adapted to the movable clamp rod 3032 is provided at the end of the material picking rod 7. In application, the movable clamp rod 3032 is clamped in the slot 71, and the clamping force is provided by the torsion spring, so that the chuck 3031 can clamp the material picking rod 7 and can drive the material picking rod 7 to rotate under the drive of the rotating motor.

[0038] In this embodiment, the reel 8 is rotatably connected between the two support frames 2, and a slide groove 202 is provided on the opposite sides of the two support frames 2. The slide groove 202 is arranged along the length direction of the liquid storage tank 11. The flexible body 81 can be a rolling curtain, and the movable end of the rolling curtain is slidably inserted in the slide groove 202. The reel 8 is driven by a driving motor to rotate so that the movable end of the rolling curtain can slide in the slide groove 202 to unfold the rolling curtain. Through the above arrangement, this embodiment can unfold the rolling curtain before the cleaning operation starts, so that the rolling curtain completely covers the liquid storage tank 11 and isolates the liquid storage tank 11, so as to prevent the alcohol and resin curing agent sprayed by the softening liquid nozzle 4 and the coagulant nozzle 5 from flowing into the liquid storage tank 11 after the cleaning operation starts, and contaminating the photosensitive resin stock solution in the liquid storage tank 11.
