Description

TECHNICAL FIELD

[0001] The present application relates to the field of laser cutting equipment, in particular to a five-axis laser cutting equipment with positioning and clamping functions for dental mold manufacturing. BACKGROUND

[0002] Through the 3D printing technology, the dental mold can be mass-produced without opening the mold. After the dental mold is produced, the laser cutting equipment is used to cut the excess support structure on the surface of the dental mold. The transport equipment is used to transport the batch of dental molds. The mechanical hand is used to place the dental mold on the five-axis machine table. The laser is used to cut the excess structure on the surface of the dental mold. After the cutting is completed, the mechanical hand is used to take the dental mold off the five-axis machine table and place it in the material receiving frame.

[0003] When the dental mold is placed on the five-axis machine table, the limiting structure on the five-axis machine table is used to limit the dental mold. At present, when the dental mold is manufactured by 3D printing, a limiting hole is reserved on the support structure of the dental mold, and a corresponding limiting pin is reserved on the five-axis machine table. When the mechanical hand places the dental mold on the five-axis machine table, the limiting pin cooperates with the limiting hole to limit the dental mold, which facilitates the adjustment of the position of the dental mold by the five-axis machine table. However, in order to ensure that the limiting pin can be quickly and smoothly embedded in the limiting hole, when the dental mold is formed by the 3D printing equipment, the inner diameter size of the limiting hole is slightly larger than the outer diameter size of the limiting pin. When the five-axis machine table is tilted and offset, the dental mold will be slightly offset on the five-axis machine table, thereby affecting the cutting precision of the laser beam on the excess structure of the dental mold.

[0038] Embodiment three: please refer to Figure 7 , this embodiment is a further description of other embodiments, both ends of the second rotating shaft 44 rotatably penetrate out of the moving platform 7, and the outer surface of the end of the second rotating shaft 44 away from the first bevel gear 34 is fixedly sleeved with a brush plate 43, when the second rotating shaft 44 rotates with the brush plate 43, the bristles of the brush plate 43 can brush out the impurities in the tooth groove 30.

[0039] Both ends of the tooth groove 30 are provided with a circular arc chamfer, and the circular arc chamfer can more conveniently brush out the impurities in the tooth groove 30 by the bristles of the brush plate 43.

[0040] Working principle: when the dental model is placed on the top of the second limiting seat 11, the moving platform 7 needs to be moved to the front end of the slide rail seat 5, that is, the end far away from the lower side of the laser polarization lens 4, through the driving motor 12, at this time, the moving platform 7 is in the Figure 2 position state, so as to facilitate the mechanical hand to place the dental model on the top of the second limiting seat 11, and in the process of placing, the bolt 20 can be inserted into the limiting hole of the dental model;

[0041] The driving motor 12 drives the mobile platform 7 to move the dental mold to the front of the laser polarization lens 4. During the movement, the winding shaft 33 winds the traction rope 29 through the meshing of the transmission gear 32 and the gear slot 30, thereby pulling down the second movable disc 18. When the slide rod 25 moves downward with the trapezoidal block 26, the end of the slide column 22 is pushed, the bottom of the limiting column 24 is pushed out and abuts against the inner wall of the limiting hole of the dental mold, and the dental mold is limited and fixed. When the trapezoidal block 26 moves downward and pushes the slide column 22 to the position where it cannot continue to move, the tension spring 19 is stretched, and the reaction force generated by the tension spring 19 also tightly abuts the limiting column 24 against the inner wall of the limiting hole, thereby ensuring that the dental mold is stably limited on the upper end surface of the second limiting seat 11. Regardless of the deflection of the upper end surface of the second limiting seat 11, the dental mold will not be offset, thereby ensuring the precision of the laser cutting of the dental mold.

[0042] Each time the mobile platform 7 moves, the second shaft 44 rotates through the meshing of the first bevel gear 34 and the second bevel gear 35, thereby allowing the brushes of the two brush plates 43 to brush off the impurities accumulated in the gear slot 30, avoiding excessive accumulation of impurities affecting the transmission of the transmission gear 32. Moreover, when the second shaft 44 rotates, it also rotates the push-moving disc 36, which can alternately push the two push rods 45 on the same side through the triangular protrusions on the end surface of the push-moving disc 36. Under the action of the first one-way valve, the second one-way valve and the third spring 39, high-pressure gas can be continuously input into the hollow tube 41 and output through the exhaust pipes 42. The high-pressure airflow on the surface of the gear slot 30, combined with the action of the brush plate 43, can more effectively ensure the cleanliness of the inside of the gear slot 30 and prevent the accumulation of particulate impurities.

[0043] It should be noted that, in the present text, relational terms such as first and second and the like can only be used to distinguish one entity or operation from another entity or operation, without necessarily requiring or implying any such actual relationship or order between these entities or operations.
