Description

Technical Field

[0001] This utility model relates to the field of dental mold manufacturing technology, specifically to a blanking mechanism for a five-axis laser cutting device for dental mold manufacturing. Background Technology

[0002] 3D printing technology allows for the mass production of dental molds without the need for mold making. After the dental molds are produced, the excess support structures on the surface of the dental molds need to be cut off using laser cutting equipment. The batch of dental molds are then transported by transport equipment, and the excess structures on the surface of the dental molds are cut off again using five-axis laser cutting equipment.

[0003] In dental mold processing, a robotic arm is needed to pick up and transport the material from the unloading mechanism to a five-axis laser cutting equipment for cutting. However, if the existing conveyor belt becomes loose or the position is not accurately locked, the robotic arm may not be able to complete the gripping action, resulting in empty space. To address this, we propose an unloading mechanism for a five-axis laser cutting equipment for dental mold manufacturing. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-5This utility model provides a technical solution: a material feeding mechanism for a five-axis laser cutting equipment for dental mold manufacturing, including a work frame 1 and a five-axis laser cutting machine 2. The five-axis laser cutting machine 2 is fixedly installed on the work frame 1. A material conveying mechanism 3 for material conveying is fixedly installed on the top of the work frame 1 and on one side of the five-axis laser cutting machine 2. A position locking mechanism 4 for positioning the material is provided on the top of the work frame 1 and between the material conveying mechanisms 3. Multiple sets of position locking mechanisms 4 are provided. A support frame 5 is fixedly installed on the top of the work frame 1 and at one end of the material conveying mechanism 3. A material picking mechanism 6 for picking up the material and placing it onto the material conveying mechanism 3 is provided on the support frame 5.

[0016] The five-axis laser cutting machine 2 can cut the dental molds. The material handling mechanism 6 can pick up the dental molds to be processed one by one and move them to the material conveying mechanism 3. The material conveying mechanism 3 can always be in a tensioned state during use to prevent the position from shifting during material conveying. The position locking mechanism 4 can ensure that the position of the dental mold is relatively accurate when it needs to be picked up, and the normal conveying and unloading of the dental mold will not be affected by the material coming from behind.

[0017] Please see Figure 1 and Figure 5 The material handling mechanism 6 includes a screw slide 28, a third drive cylinder 29, a third connecting frame 30, a picking plate 31, and a suction head 32. The moving end of the screw slide 28 is fixedly connected to the third drive cylinder 29, and the output end of the third drive cylinder 29 is fixedly connected to the picking plate 31 through the third connecting frame 30. Multiple suction heads 32 are provided on the picking plate 31.

[0018] When it is necessary to pick up and unload materials, the third drive cylinder 29 drives the third connecting frame 30, the picking plate 31 and the suction head 32 to descend, and uses the suction head 32 to pick up the dental mold. The screw slide 28 then drives the dental mold on the suction head 32 to be transported to the material conveying mechanism 3.

[0019] Please see Figures 1-4The material conveying mechanism 3 includes a conveying frame 7, a first driven synchronous pulley 8, a first mounting plate 9, a rotating shaft 10, a first driving synchronous pulley 11, a drive motor 12, a second driving synchronous pulley 13, and a second driven synchronous pulley 14. Two sets of first driven synchronous pulleys 8 are fixedly installed on the conveying frame 7. Two sets of first mounting plates 9 are fixedly installed on the conveying frame 7. The rotating shaft 10 is rotatably connected between the two sets of first mounting plates 9. The first driving synchronous pulley 11 is fixedly connected to the outside of the rotating shaft 10. The second mounting plate 33 is fixedly installed at the bottom of the conveying frame 7. The drive motor 12 is fixedly connected to one side of the second mounting plate 33. The second driving synchronous pulley 13 is fixedly connected to the output end of the drive motor 12. The second driven synchronous pulley 14 is fixedly connected to one end of the rotating shaft 10. A first synchronous belt 15 is provided outside the second driving synchronous pulley 13 and the second driven synchronous pulley 14. A second synchronous belt 16 is provided outside the first driven synchronous pulley 8 and the first driving synchronous pulley 11.

[0020] The dental mold picked up by the material handling mechanism 6 is placed on the second synchronous belt 16. Then, the rotation of the drive motor 12 can drive the second driven synchronous belt pulley 14, the rotating shaft 10 and the first driving synchronous belt pulley 11 to rotate through the second driving synchronous belt pulley 13 and the first synchronous belt 15. In this way, the second synchronous belt 16 can rotate along the first driving synchronous belt pulley 11 and the first driven synchronous belt pulley 8, thereby conveying the dental mold placed on the second synchronous belt 16 forward.

[0021] Please see Figures 1-4 The material conveying mechanism 3 also includes an adjustment groove 17, a first connecting frame 18, a locking bolt 19, and an auxiliary synchronous pulley 20. The bottom of the conveying frame 7 is provided with an adjustment groove 17. The first connecting frame 18 is provided with a locking bolt 19 fixed inside the adjustment groove 17. The auxiliary synchronous pulley 20 is rotatably connected to one side of the first connecting frame 18. The outer wall of the second synchronous belt 16 is in contact with the outer wall of the auxiliary synchronous pulley 20.

[0022] One side of the second synchronous belt 16 is in contact with the outer wall of the auxiliary synchronous pulley 20. When the second synchronous belt 16 becomes loose, the locking bolt 19 is unscrewed. Then, the locking bolt 19 and the first connecting bracket 18 are moved along the inside of the adjusting groove 17 and the bottom of the conveying frame 7. In this way, the second synchronous belt 16 can be tensioned by using the auxiliary synchronous pulley 20.

[0023] Please see Figures 1-4 The material conveying mechanism 3 also includes a support plate 21 and a clearance groove 22. The inner wall of the conveying frame 7 is fixedly connected to the support plate 21, which is in contact with the inner wall of the second synchronous belt 16. Both ends of the support plate 21 are provided with inclined clearance grooves 22.

[0024] The support plate 21 is in contact with the inner wall of the second synchronous belt 16, which can prevent the second synchronous belt 16 from being excessively squeezed, deformed and aged due to the weight of the dental mold itself. The inclined relief groove 22 can prevent the second synchronous belt 16 from contacting the edge of the support plate 21 and causing scratches.

[0025] Please see Figures 1-3 The position locking mechanism 4 includes a first drive cylinder 24, a blocking plate 25, a second drive cylinder 26, and a positioning seat 27. The first drive cylinder 24 is fixedly installed on the top of the work frame 1 through a second connecting frame 23. The output end of the first drive cylinder 24 is fixedly connected to an "L"-shaped blocking plate 25. The first drive cylinder 24 and the blocking plate 25 are both set in two sets. The second drive cylinder 26 is fixedly installed on the top of the work frame 1 and on one side of the first drive cylinder 24. The output end of the second drive cylinder 26 is fixedly connected to a positioning seat 27 for positioning and lifting the material.

[0026] When the second synchronous belt 16 is conveying forward, the first drive cylinder 24 drives the "L"-shaped blocking plate 25 to extend and block the dental mold. Then, the second drive cylinder 26 drives the positioning seat 27 to lift up, so that the dental mold can be lifted and positioned, making it convenient for the external robot to pick up the dental mold. The multiple sets of first drive cylinders 24 and blocking plates 25 can prevent the dental mold lifting operation from being affected by the subsequent entry of dental molds when the front positioning seat 27 lifts the dental mold.

[0027] In use, the five-axis laser cutting machine 2 first cuts the dental molds. Then, the material handling mechanism 6 picks up the dental molds one by one and moves them onto the material conveying mechanism 3. The material conveying mechanism 3 is always taut to prevent positional shifts during material transport. The subsequent position locking mechanism 4 ensures that the dental molds are accurately positioned when picked up, and that incoming materials do not interfere with normal material feeding. When picking up or unloading is required, the third drive cylinder 29 drives the third connecting frame 30... The pick-up plate 31 and suction head 32 descend, and the suction head 32 picks up the dental mold. The screw slide 28 then drives the dental mold on the suction head 32 to be conveyed above the material conveying mechanism 3. The dental mold picked up by the picking mechanism 6 is placed on the second synchronous belt 16. The rotation of the drive motor 12 then uses the second driving synchronous pulley 13 and the first synchronous belt 15 to drive the second driven synchronous pulley 14, the rotating shaft 10, and the first driving synchronous pulley 11 to rotate. This causes the second synchronous belt 16 to rotate along the first driving synchronous pulley 11 and the first driven synchronous pulley 15, thus allowing the dental mold placed on the second synchronous belt 16 to rotate. The dental mold on the stepping belt 16 is conveyed forward. One side of the second synchronous belt 16 contacts the outer wall of the auxiliary synchronous pulley 20. When the second synchronous belt 16 becomes loose, the locking bolt 19 is unscrewed, and then the locking bolt 19 and the first connecting bracket 18 are moved along the inside of the adjusting groove 17 and the bottom of the conveying frame 7. In this way, the auxiliary synchronous pulley 20 can be used to tension the second synchronous belt 16. The support plate 21 contacts the inner wall of the second synchronous belt 16, thereby preventing the second synchronous belt 16 from being excessively squeezed, deformed, or aged due to the weight of the dental mold itself. The recessed clearance groove 22 can prevent the second synchronous belt 16 from contacting the edge of the support plate 21 and causing scratches. When the second synchronous belt 16 is conveyed forward, the first drive cylinder 24 drives the "L"-shaped blocking plate 25 to extend and block the dental mold. Then the second drive cylinder 26 drives the positioning seat 27 to lift up, so that the dental mold can be lifted and positioned, making it convenient for the external robot to pick up the dental mold. The multiple sets of first drive cylinders 24 and blocking plates 25 can prevent the dental mold lifting operation from being affected by the subsequent entry of dental molds when the front positioning seat 27 lifts the dental mold.
