Description

Technical Field

[0001] The utility model relates to the technical field of denture processing, in particular to a material hooking module, a material tray matched with the material hooking module and a denture carving machine. Background Art

[0002] The loading module of a denture engraving machine refers to a device used to automatically place raw materials (such as zirconia or other processing materials) accurately onto the engraving machine workbench during the engraving process. The module usually includes a fixture, a feeding mechanism, and a sensor to ensure that the material can be positioned securely and accurately for subsequent processing by the engraving machine.

[0003] The importance of the loading module lies in its direct impact on the efficiency and accuracy of the engraving process. Specifically, an efficient and accurate loading module can reduce material waste, increase production speed, and reduce operator workload. Furthermore, a well-designed loading system ensures consistency and quality in denture processing, reduces human error, and ultimately improves the reliability of the final product.

[0004] The utility model patent with authorization announcement number CN214562011U discloses a feeding docking device for a denture engraving machine and a denture engraving machine, such as Figure 1 As shown, the loading and docking device includes: a carrier plate clamping mechanism 100, a transfer mechanism, a zirconia carrier plate 200 and a processing frame, wherein the carrier plate clamping mechanism 100 is used to clamp the zirconia carrier plate 200 in the first position, and is used to push the zirconia carrier plate 200 to a specified position in the second position to clamp the processing frame; the transfer mechanism is used to drive the carrier plate clamping mechanism 100 to move between the first position and the second position; the zirconia carrier plate 200 is used to carry zirconia; the processing frame is used to connect the zirconia carrier plate 200 and drive the zirconia carrier plate 200 to rotate under the drive of the A-axis and B-axis drive sources.

[0005] The loading and docking device for a denture engraving machine provided by this utility model patent is designed to provide docking grooves at the two ports of the zirconia carrier, and to adapt the docking grooves to set clamping components. When the zirconia carrier needs to be replaced, the carrier clamping mechanism can clamp the zirconia carrier from both ends, thereby solving the problems of low material utilization and manual material replacement in traditional denture engraving machines. However, on the one hand, the structure requires two sets of symmetrically arranged finger cylinders and corresponding clamping structures, resulting in a more complex overall design and high requirements for alignment accuracy, which increases the difficulty of operation. On the other hand, during the processing, the zirconia material will generate a large amount of dust, which can easily be contaminated by the movable joints of the finger cylinders, affecting the normal rotation and performance of the finger cylinders, resulting in lower processing accuracy.

[0006] Therefore, the prior art needs to be improved and perfected. Utility Model Content

[0007] In view of the above-mentioned deficiencies in the prior art, the purpose of the present utility model is to provide a hooking module, a material tray and a denture engraving machine compatible with the hooking module, aiming to solve the problem that the existing loading module needs to be equipped with two sets of symmetrically arranged finger cylinders and corresponding clamping structures, which makes the overall design more complicated and the positioning accuracy requirements are high, which increases the difficulty of operation; and during the processing, the zirconia material will produce a large amount of dust, which is easy to be contaminated by the movable joints of the finger cylinders, affecting the normal rotation and performance of the finger cylinders, resulting in low processing accuracy.

[0008] The technical solution of the utility model is as follows:

[0009] A material hooking module for a denture engraving machine includes: a longitudinal drive mechanism, which also includes: a material hook. The longitudinal drive mechanism is connected to the upper end of the material hook and is used to drive the material hook to move up and down; the material hook is used to hook the hooked part on the material tray from below to prepare for loading.

[0010] The above solution is effective in that, compared to the finger cylinders and complex longitudinal drive structures in traditional feeding modules, the hook module of the present invention relies solely on a longitudinal drive mechanism to drive the hook up and down, effectively simplifying the structure of the entire feeding device and reducing the difficulty of operation. Furthermore, because the present invention eliminates the need for clamping components and docking slots, the requirements for alignment accuracy are reduced, allowing operators to complete feeding operations more quickly. Furthermore, the hook is designed to penetrate deep into the processing cavity and remain fixed, eliminating the need for rotation or other complex movements. Therefore, even if dust adheres to the hook during processing, it will not affect its normal operation, thereby improving processing accuracy and the overall reliability of the equipment.

[0011] In a further preferred embodiment, the material hook includes a fixing plate and two hook bodies, the fixing plate is provided with a receiving groove on a side facing the material tray, the receiving groove is used to accommodate the upper end of the material tray, the two hook bodies are respectively used to adapt to two hooked parts, and are respectively located on the outside of the lower end of the fixing plate, so that after the material hook hooks the hooked part, the upper end of the material tray is accommodated in the receiving groove.

[0012] The effect of the above solution is that when the two hook bodies hook the two hooked parts at the same time, the upper end of the material tray will be accommodated in the receiving groove and fit with the bottom wall of the receiving groove, so that the hook module and the material tray are firmly connected together. Therefore, the design of the receiving groove in the fixed plate ensures that the upper end of the material tray can be firmly accommodated in the groove, enhancing the connection stability between the hook assembly and the material tray, reducing the shaking that may occur in the material tray during the loading process, thereby improving the accuracy of grasping and the position accuracy of the material tray when loading onto the workbench. The configuration of the two hook bodies enables them to adapt to the two hooked parts at the same time, which ensures the balance of force on both sides of the material tray, ensuring that when the transfer mechanism drives the hook module to move, the material tray will not be offset due to uneven force, further ensuring the stability of the material tray during movement.

[0013] In a further preferred embodiment, the hook body is provided with a hook groove, the upper end of which is an open port so that the hooked piece automatically enters the hook groove when the hook moves upward; the bottom of the hook groove is semicircular to accommodate the cylindrical hooked piece.

[0014] The effect of the above scheme is that when the hook groove of the hook body is driven by the transfer mechanism (i.e., the three-axis drive mechanism) of the denture engraving machine and moves to the bottom of the hooked part, the preliminary alignment is completed. Next, the longitudinal drive mechanism starts to drive the material hook to move upward, and at this time the hooked part automatically enters the hook groove. Since the cylindrical shape of the hooked part matches the semicircular shape of the bottom of the hook groove, the hooked part can automatically slide to the preset position during the continuous upward movement of the longitudinal drive mechanism, ensuring the accuracy of the position. In addition, since the design allows the material hook to continue to move upward without pausing, the requirements for clamping stability during the loading process are reduced, thereby improving the smoothness and efficiency of the overall operation. The seamless workflow not only improves the degree of automation, but also significantly reduces the dependence on operating accuracy, making the entire loading process more efficient and reliable.

[0015] In a further preferred embodiment, a fitting protrusion is provided at the bottom of the receiving groove facing the material tray, and the fitting protrusion is used to fit the material tray so that a gap is formed between the receiving groove portion above the fitting protrusion and the material tray.

[0016] The effect of the above solution is that the setting of the fitting protrusion reduces the contact area between the material tray and the material hooking module, so that when the material hooking module is hooking the material, there will not be much friction between the material tray and the wall of the receiving groove, thereby reducing the loss of material due to friction and extending the service life of the material tray and the material hooking module. In addition, the design can also reduce the heat generated by friction, thereby avoiding deformation or damage of the material due to overheating. When the material tray is placed on the workbench, there will also be no significant friction between the material tray and the wall of the receiving groove, so as to ensure the smooth operation of the material tray during the installation process, reduce the requirements for operating accuracy, and reduce the difficulty of operation. Therefore, by reducing the contact area and friction through the above setting, the overall system can achieve a smoother workflow, improve the working efficiency and processing quality of the denture engraving machine, and also help maintain the stability and reliability of the system.

[0017] In a further preferred embodiment, a sensor is provided on the side of the fixed plate facing away from the material tray, and a penetration hole is provided to adapt to the sensor. The sensor is used to detect the positioning hole on the material tray through the penetration hole, so that the longitudinal drive mechanism drives the material hook to move upward after hooking the material tray.

[0018] The effect of the above scheme is that the fitting protrusions set above and the gaps they can produce not only reduce the contact area between the material tray and the hooking module, but also provide an effective working space for the sensor. The sensor can accurately align with the positioning hole on the material tray through the penetration hole, thereby ensuring that when the longitudinal drive mechanism drives the material hook to move upward, the material hook can accurately hook the material tray. At the same time, accurate positioning can ensure that the material hook always remains stable during the upward movement process, preventing the risk of grasping failure or falling off due to inaccurate positioning. It can be understood that this setting does not conflict with the technical effect of the hooking trough. Although the hooking trough and related settings enable the hooking module to move up and feed the material to the workbench without pause when hooking the material, the short pause does not have much effect on work efficiency, and the setting of the specific operating program can be flexibly selected and adjusted by those skilled in the art.

[0019] In a further preferred embodiment, the longitudinal driving mechanism is connected to a guide mechanism, and is connected to the material hook via the guide mechanism.

[0020] The effectiveness of this solution lies in the following: the guide mechanism provides a stable path for the hook, enabling smoother and more accurate up and down movement, effectively reducing swing and deviation during movement and improving gripping accuracy. Furthermore, the guide mechanism effectively guides the hook's movement during operation, ensuring it remains in the ideal operating position, further improving loading efficiency and reliability.

[0021] In a further preferred embodiment, two guide mechanisms are provided, namely a first guide mechanism and a second guide mechanism. The first guide mechanism includes an I-shaped guide rail, and the second guide mechanism includes a guide slide bar.

[0022] The effectiveness of this solution lies in the following: the I-shaped guide rail, serving as the primary guide mechanism, provides strong support for the material hook, ensuring it maintains a straight trajectory during vertical movement, effectively preventing tilting and swinging caused by gravity or external interference. The guide slide of the secondary guide mechanism reduces frictional resistance, ensuring smoother movement of the material hook. This combination of the two achieves higher operational accuracy and reliability, improving stability during the grasping process and reducing the risk of grasping failure and material damage caused by unstable movement.

[0023] In a further preferred embodiment, two guide slide bars are provided, and the two guide slide bars are adapted to the same guide block.

[0024] The benefits of this solution are as follows: Two guide slides fit onto the same guide block, enhancing the stability of the hook and making it less likely to deflect or swing during up and down movement. This significantly improves gripping accuracy and reduces the risk of gripping failure due to deviation. Furthermore, the two guide slides provide a more even distribution of force, effectively reducing the load on a single guide slide, reducing wear and extending the life of the guide mechanism. Furthermore, the parallel configuration of the guide slides provides better support, allowing the hook to maintain better balance during movement and reducing noise and vibration caused by imbalance.

[0025] A material tray compatible with the above-mentioned hooking module includes a hooked part, which is used to be hooked by the hooking module and then prepared for loading. The hooking module ensures that the hooked part on the material tray can be accurately and stably grasped and moved through the above-mentioned settings, such as the guide mechanism and the hooking groove, which directly affects the efficiency and accuracy of the loading process. When the hooked part is on the material tray, its shape and setting should match the hooking module so that the module can smoothly hook and lift the hooked part to prepare for loading. The setting of the material tray provides conditions suitable for the working of the hooking module, and the hooking module ensures the stability and safety of the hooked part on the material tray through its efficient working method. This mutually adaptive relationship ensures the smooth operation of the entire system and improves the production efficiency and processing quality of the denture engraving machine.

[0026] A denture engraving machine includes the material hooking module for denture engraving machines described above. Since the denture engraving machine includes all the technical features of the material hooking module for denture engraving machines described above, the denture engraving machine also has all the technical effects of the material hooking module for denture engraving machines described above, and no further details are given.

[0027] Compared with the prior art, the material hook module for the denture engraving machine provided by the present invention includes a longitudinal drive mechanism and a material hook. The longitudinal drive mechanism is connected to the upper end of the material hook and is used to drive the material hook to move up and down; the material hook is used to hook the hooked part on the material tray from below to prepare for loading. The material hook module of the present invention only needs to rely on the longitudinal drive mechanism to drive the material hook to move up and down, thereby effectively simplifying the structure of the entire loading device and reducing the difficulty of operation. In addition, since the present invention eliminates the need for clamping components and docking grooves, the requirements for positioning accuracy are reduced, allowing operators to complete loading operations more quickly. At the same time, the material hook is designed to penetrate deep into the processing cavity and remain fixed, without the need for rotation or other complex movements. Therefore, even if dust adheres to the material hook during processing, it will not affect its normal operation, thereby improving the processing accuracy and the overall reliability of the equipment.

[0039] The present invention provides a material hooking module, a material tray compatible with the material hooking module and a denture engraving machine. In order to make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples.

[0040] The utility model provides a material hooking module for a denture engraving machine, such as Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, it includes: a longitudinal drive mechanism 110 (such as Figure 9 The hook 130 is connected to the upper end of the hook 130 and is responsible for driving the hook 130 up and down. The hook 130 is specifically designed to hook the hooked member 210 on the material tray 200 from below to prepare for loading. It should be noted that the material tray 200 and the hooked member 210 are not part of the hooking module, but for the purpose of more clearly illustrating the specific embodiment of the present invention, Figures 2 to 5 This is marked.

[0041] The hooking module provided by the present invention can be divided into three automated processes when loading materials:

[0042] Picking up materials: When picking up materials, the longitudinal driving mechanism 110 of the hooking module moves the material hook 130 to the bottom of the material tray 200 (it can be seen that Figure 2 and Figure 3 The hook is shown positioned below and to the side of the tray 200; the next step is to move it directly below the tray 200. Because the hook 130 is designed to match the shape of the hooked part 210, it can accurately engage the hooked part 210. Compared to the finger cylinders and complex structures of traditional loading modules, the present invention simplifies the entire material removal process, making it more direct and efficient. Furthermore, by eliminating the need for a clamping assembly and docking slots, the alignment requirements are reduced, allowing operators to complete the material removal operation more quickly.

[0043] Moving the Tray 200: After removing the material, the longitudinal drive mechanism 110 continues to drive the hook 130 upward, lifting the hooked tray 200 along with it. During this process, the hook 130 remains stationary, eliminating the need for rotation or other complex movements, thus ensuring stability. This design is particularly important in dusty processing environments, as even if dust adheres to the hook 130, it will not affect its normal upward movement, ensuring smooth movement and effective gripping of the tray 200.

[0044] Placing the tray 200: When the tray 200 is moved to the target location, the longitudinal drive mechanism 110 lowers the hook 130, safely placing the tray 200 in the designated location. Due to the simplified design of the system, the placement process is faster and more accurate, greatly improving the efficiency of loading.

[0045] In a further preferred embodiment of the present invention, the material hook 130 is additionally provided with a fixing plate 131. Figure 6 As shown, the fixing plate 131 has a receiving groove 131a on the side facing the material tray 200 for accommodating the upper end of the material tray 200. Two hooks 133 are installed on the outer side of the lower end of the fixing plate 131. The two hooks 133 are respectively adapted to the two hooked parts 210. During operation, the material hook 130 can hook the two hooked parts 210 at the same time, ensuring that the upper end of the material tray 200 is firmly placed in the receiving groove 131a.

[0046] During operation, when the two hooks 133 simultaneously move upward and hook the two hooked parts 210, the upper end of the material tray 200 is effectively accommodated in the receiving groove 131a and closely contacts the groove bottom wall (i.e., its wall is in contact with the material tray 200), ensuring a firm connection between the hooking module and the material tray 200. This significantly reduces the shaking of the material tray 200 during the loading process and enhances the accuracy of the grip. In addition, the presence of the receiving groove 131a ensures that the material tray 200 can be accurately positioned when loading onto the workbench, avoiding errors caused by shaking.

[0047] The configuration of the two hooks 133 enables them to engage two hooked parts 210 simultaneously, further enhancing force balance. When the transfer mechanism drives the hook module to move, the forces on both sides of the tray 200 remain balanced, preventing positional shifts caused by uneven forces. This balanced force ensures the stability of the tray 200 throughout the entire movement process, effectively improving the efficiency and accuracy of loading. Therefore, the fixed plate 131 and its receiving slot 131a play a key role in improving the overall performance of the hook module, ensuring the efficiency and stability of the entire loading process.

[0048] Furthermore, the material hook 130 is provided with a material hook groove 133a. Figure 6 As shown, its upper end is an open port so that the hooked member 210 can automatically enter the hooking groove 133a when the material hook 130 moves upward. At the same time, the bottom of the hooking groove 133a is semicircular to perfectly fit the cylindrical shape of the hooked member 210 (preferably, the size of the hooking groove 133a is larger than the hooked member 210 so that the hooked member 210 can slide smoothly to the preset position without getting stuck during the sliding process due to overly tight fit).

[0049] During the loading process, when the material hook trough 133a moves to the position directly below the hooked part 210 along with the transfer mechanism (i.e., the X-axis drive mechanism, the Y-axis drive mechanism, and the Z-axis drive mechanism) of the denture engraving machine and the longitudinal drive mechanism 110, the initial alignment is completed. Subsequently, the longitudinal drive mechanism 110 begins to drive the material hook 130 upward. During this process, the hooked part 210 will naturally slide into the material hook trough 133a. Since the cylindrical shape of the hooked part 210 matches the semicircular design of the bottom of the material hook trough 133a, as the longitudinal drive mechanism 110 continues to move upward, the hooked part 210 will automatically be positioned at the preset position, ensuring the accuracy of the grasping.

[0050] The hook 130 does not need to pause during its upward movement (although with other optimized configurations, such as sensors detecting the relative position of the hook module and the tray 200, a brief pause can be implemented during the upward movement). This reduces the need for clamping stability and improves operational fluidity and efficiency. The seamless operation not only improves automation but also significantly reduces reliance on operational precision, making the entire loading process more efficient and reliable.

[0051] Preferably, the bottom of the receiving groove 131a is provided with a fitting protrusion 132 on the side facing the tray 200, such as Figure 6 As shown, the main purpose of the fitting protrusion 132 is to form a gap JX above the fitting protrusion 132 while making the hooking module closely fit the material tray 200, as shown in FIG. Figure 7 shown.

[0052] On the one hand, the provision of the fitting protrusions 132 significantly reduces the contact area between the material tray 200 and the material hooking module. This prevents excessive friction between the material tray 200 and the wall of the receiving groove 131a during the material hooking operation, thereby reducing material loss caused by friction and extending the service life of the material tray 200 and the material hooking module. On the other hand, the reduced friction also means less heat is generated during operation, which can prevent the risk of material deformation or damage due to overheating. In addition, when the material tray 200 is placed on the workbench, the friction between the receiving groove 131a and the material tray 200 remains low, ensuring a smooth installation process, thereby reducing the reliance on operational precision and reducing the difficulty of operation.

[0053] Preferably, the back of the fixing plate 131 is provided with a sensor 140, such as Figure 7 and Figure 8As shown, the sensor 140 is adapted to have a through-hole 131b on the fixing plate 131, allowing the sensor 140 to detect the positioning hole on the material tray 200 through this hole. This allows the longitudinal drive mechanism 110 to accurately identify and align the positioning hole on the material tray 200 before driving the material hook 130 upward. The provided fitting protrusion 132 and the gap it creates not only effectively reduce the contact area between the material tray 200 and the hooking module, but also provide the necessary working space for the sensor 140, allowing the sensor 140 to accurately align with the positioning hole on the material tray 200. This ensures that the material hook 130 can securely hook the material tray 200 when the longitudinal drive mechanism 110 drives the material hook 130 upward. Secondly, precise alignment ensures that the material hook 130 remains stable during the upward movement process, significantly reducing the risk of grasping failure or disengagement due to inaccurate positioning. It can be seen that the technical effects of this arrangement and the material hook groove 133a are complementary (there is an organic connection between the two). It's easy to understand that while the design of the material chute 133a allows the material chute module to continuously move upward while loading, the impact of brief pauses on work efficiency is minimal, and the specific operating procedures can be flexibly adjusted and optimized by professionals. Therefore, overall, this optimized embodiment improves operational accuracy and reliability, ensuring an efficient automated loading process.

[0054] According to another aspect of the present invention, the longitudinal drive mechanism 110 and the guide mechanism 120 (such as Figure 2 、 Figure 4 and Figure 5 ) and is connected to the material hook 130 via the guide mechanism 120. As can be seen, the guide mechanism 120 provides a stable path for the material hook 130, making its vertical movement smoother and more precise. This effectively reduces swinging and deviation during movement, improving gripping accuracy. Furthermore, the guide mechanism 120 effectively directs the movement of the material hook 130, ensuring it always remains in the optimal operating position, further enhancing the efficiency and reliability of the loading process.

[0055] Furthermore, the guide mechanism 120 is composed of two parts, namely a first guide mechanism 121 and a second guide mechanism 122. Figure 10 and Figure 11 As shown, the first guide mechanism 121 is an I-shaped guide rail (such as Figure 11 As shown), the second guide mechanism 122 is a guide slide bar (as shown Figure 11(As shown). The I-shaped guide rail, serving as the first guide mechanism 121, provides solid support for the material hook 130, ensuring it follows a straight trajectory during up and down movement, effectively preventing tilting and swinging caused by gravity or external interference. Simultaneously, the guide slide of the second guide mechanism 122 significantly reduces frictional resistance, ensuring smoother movement of the material hook 130. This combination not only improves the system's operational accuracy and reliability, but also enhances stability during the grasping process, reducing the risk of grasping failure and material damage caused by unstable movement.

[0056] In practice, two guide slides are configured, and they are coupled to a guide block. This arrangement enhances the stability of the hook 130, ensuring less deviation and swing during its upward and downward movement. This improves the accuracy of the grasping process and reduces the risk of grasping failure due to deviation. Furthermore, the design of two guide slides ensures more even force distribution, effectively reducing the load borne by a single guide slide, reducing wear and tear, and thus extending the service life of the guide mechanism 120. Furthermore, the parallel configuration of the guide slides provides better support, allowing the hook 130 to maintain better balance during movement, thereby reducing noise and vibration caused by imbalance.

[0057] A material tray 200 adapted to the above-mentioned material hooking module, such as Figure 2 、 Figure 4 and Figure 5 As shown, it includes a hooked member 210 (such as Figures 2 to 5 As shown), the hooked part 210 is used to be hooked by the hooking module and then prepared for loading. The hooking module ensures that the hooked part 210 on the material tray 200 can be accurately and stably grasped and moved through the above-mentioned settings, such as the guide mechanism 120 and the hooking groove 133a, which directly affects the efficiency and accuracy of the loading process. When the hooked part 210 is on the material tray 200, its shape and setting should match the hooking module so that the module can smoothly hook and lift the hooked part 210 to prepare for loading. The setting of the material tray 200 provides conditions suitable for the working of the hooking module, and the hooking module ensures the stability and safety of the hooked part 210 on the material tray 200 through its efficient working method. This mutually adaptive relationship ensures the smooth operation of the entire system and improves the production efficiency and processing quality of the denture engraving machine.

[0058] Preferably, the hooked member 210 is cylindrical, and the material tray 200 is further provided with a positioning hole, as specifically described above.

[0059] The present invention also provides a denture engraving machine, which includes the material hooking module for the denture engraving machine as described above. Since the denture engraving machine includes all the technical features of the material hooking module, the denture engraving machine also has all the technical effects of the material hooking module, which will not be described in detail.
