Description

Technical Field

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

[0002] Existing laser cutting equipment for dental mold manufacturing often uses a feeding mechanism to transport the dental mold. The core conveyor belt is mainly used as the conveying component, supplemented by a simple limiting structure, to send the dental mold to the designated station and complete the dental mold processing with the cutting components.

[0003] However, the existing material supply mechanism has obvious drawbacks: it lacks an automatic control and stop mechanism after the dental mold is in place, and the conveyor belt often runs continuously. This causes the dental mold to continue to be rubbed by the conveyor belt after it stops at the limit structure, which can easily cause wear and deformation of the dental mold edge and affect the subsequent cutting accuracy. In addition, it requires manual monitoring of the dental mold position and manual start and stop of the conveyor belt, which not only increases labor costs, but also easily leads to disorder of the material supply rhythm due to operation delays, reduces the dental mold manufacturing efficiency, and is difficult to adapt to the needs of automated production.

[0004] Based on this, a feeding mechanism for a five-axis laser cutting device for dental mold manufacturing is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding mechanism for a five-axis laser cutting device for dental mold manufacturing in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A feeding mechanism for a five-axis laser cutting device for dental mold manufacturing includes a support frame with a limiting edge connected to the support frame. A conveyor belt is connected to one side of the limiting edge, and a control unit for controlling the operation of the conveyor belt is connected to the other side of the limiting edge. A baffle is connected to the limiting edge, and a fixing plate is connected to the lower end of the limiting edge. A control component for cooperating with the cutting and conveying of the dental mold is connected to the fixing plate.

[0007] Preferably, the control component includes a deflection bar, a fixed shaft is connected to one side of the fixed plate, a sleeve is rotatably connected to the fixed shaft, a torsion spring is connected to one side of the sleeve via a connecting ring, and the deflection bar is fixedly connected to the outside of the sleeve.

[0008] Preferably, the baffle plate has a slot that cooperates with the deflection bar.

[0009] Preferably, a pressing frame is slidably connected to the limiting edge, a return spring is connected to the pressing frame, and a winding wheel is connected to the lower end of the pressing frame via a traction rope. The winding wheel is fixedly connected to one side of the sleeve.

[0010] Preferably, a connecting rod is connected to the outside of the sleeve, and the other end of the connecting rod is connected to the winding reel.

[0011] Preferably, the control unit is connected to a U-shaped cover and a button, the upper end of the pressing bracket is slidably connected inside the U-shaped cover, and the upper end of the pressing bracket is positioned directly above the button.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. This application achieves automatic control and stopping of the dental mold conveyor by adopting a linkage structure consisting of a deflection bar, sleeve, torsion spring, winding wheel, traction rope, pressing frame, and button. When the dental mold stops at the stop plate, it will push the deflection bar to drive the sleeve and winding wheel to rotate, and the traction rope will pull down the pressing frame to trigger the button, so that the conveyor belt will stop automatically, avoiding wear and tear on the dental mold due to continuous operation of the conveyor belt and ensuring the morphological accuracy of the dental mold.

[0013] 2. This application achieves automatic restart and material feeding cycle of the conveyor belt by adopting an elastic reset structure of torsion spring and return spring. After the dental mold is transferred, the torsion spring drives the deflection bar and sleeve to reset, the winding wheel releases the traction rope, and the return spring pushes the pressing frame to rise and disengage from the button, and the conveyor belt automatically resumes operation without manual intervention to start and stop, reducing labor costs, ensuring a stable material feeding rhythm, and adapting to the automated production needs of dental mold manufacturing.

[0016] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 This utility model provides a technical solution: A feeding mechanism for a five-axis laser cutting device for dental mold manufacturing includes a support frame 1. A limiting edge 3 is connected to the support frame 1 to limit the dental mold and prevent structural displacement during transportation. A conveyor belt 4 is connected to one side of the limiting edge 3, and a control unit 2 for controlling the operation of the conveyor belt 4 is connected to the other side of the limiting edge 3. The control unit 2 and the conveyor belt 4 are existing mature technologies, so they will not be described in detail here. A baffle 15 is connected to the limiting edge 3. The baffle 15 does not contact the conveyor belt 4 and mainly serves to limit the movement of the dental mold with the conveyor belt 4. When the dental mold contacts the baffle 15, it will not continue to move. A fixing plate 7 is connected to the lower end of the limiting edge 3. A control component for cooperating with the cutting and conveying of the dental mold is connected to the fixing plate 7.

[0018] Specifically, such as Figure 3 As shown, the control component includes a deflection bar 14, a fixed shaft 10 connected to one side of the fixed plate 7, a sleeve 13 rotatably connected to the fixed shaft 10, a torsion spring 11 connected to one side of the sleeve 13 via a connecting ring 12, the other end of the torsion spring 11 being fixedly connected to the fixed plate 7, and the deflection bar 14 being fixedly connected to the outside of the sleeve 13.

[0019] Specifically, such as Figure 3 As shown, the baffle 15 has a slot that cooperates with the deflection bar 14. By setting the slot, the baffle 15 is prevented from blocking the deflection of the deflection bar 14.

[0020] Specifically, such as Figure 3 As shown, a pressing frame 17 is slidably connected to the limiting edge 3. The pressing frame 17 is L-shaped and a return spring 18 is connected to the pressing frame 17. The return spring 18 can push the pressing frame 17 to rise in height, so that when the pressing frame 17 is not under force, the pressing frame 17 will not press the button 6. The lower end of the pressing frame 17 is connected to a winding wheel 8 through a traction rope 9. The traction rope 9 is wound on the winding wheel 8, and the winding wheel 8 is fixedly connected to one side of the sleeve 13.

[0021] Specifically, such as Figure 3 As shown, a connecting rod 16 is connected to the outside of the sleeve 13, and the other end of the connecting rod 16 is connected to the winding wheel 8. The connecting rod 16 ensures a fixed connection between the sleeve 13 and the winding wheel 8.

[0022] Specifically, such as Figure 2 As shown, the control unit 2 is connected to a U-shaped cover 5 and a button 6. When the button 6 is pressed, the conveyor belt 4 stops running. The U-shaped cover 5 limits the upper end of the pressing frame 17 to prevent the pressing frame 17 from rotating. The upper end of the pressing frame 17 is slidably connected inside the U-shaped cover 5, and the upper end of the pressing frame 17 is positioned directly above the button 6.

[0023] In summary, the feeding mechanism of the five-axis laser cutting equipment for manufacturing dental molds provided in this embodiment allows the dental mold to be laser-cut to stop moving when it comes into contact with the baffle 15 while being transported by the conveyor belt 4. At this time, the robot can move the dental mold at this position to the cutting station by clamping and transferring it.

[0024] When the dental mold moves close to the baffle 15, it will come into contact with the deflection bar 14, which will push the deflection bar 14 to deflect. This will overcome the torsion spring 11 and drive the sleeve 13 to rotate. When the dental mold moves with the conveyor belt 4 to contact the baffle 15, it will stop moving. The deflection bar 14 will deflect to its maximum state. The sleeve 13 will drive the winding wheel 8 to rotate synchronously through the connecting rod 16. This will work with the traction rope 9 to pull the pressing frame 17 down. At this time, the upper end of the pressing frame 17 will descend and press the button 6. The button 6 will control the conveyor belt 4 to stop running, so as to prevent the conveyor belt 4 from continuing to run after the dental mold stops moving and causing wear to the dental mold structure.

[0025] After the robotic arm transfers the dental mold, the deflection bar 14 can be deflected to a vertical position under the action of the torsion spring 11, and the pressing frame 17 can be raised in height under the action of the return spring 18, thereby canceling the pressing of the button 6. At this time, the conveyor belt 4 starts to run until the next dental mold to be processed moves to contact the baffle 15.

[0026] The feeding mechanism enables automatic start and stop of conveyor belt 4, avoiding wear on the dental mold structure and improving the precision of dental mold processing.

[0027] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
