Description

Technical Field

[0001] This utility model relates to the field of zirconia ceramic block surface processing technology, and more specifically, to a zirconia ceramic block surface printing positioning device. Background Technology

[0002] Zirconia ceramic blocks are primarily used for fixed denture restorations and are typically disc-shaped. The standard production process for zirconia ceramic blocks involves: adding zirconia powder into a mold and using hydraulic pressing to shape the powder into the desired form; this process can be referred to as pre-pressing. Then, isostatic pressing is used to refine the final shape. Finally, high-temperature sintering, machining, printing, and packaging result in a marketable product.

[0003] However, existing printing equipment does not have a dedicated positioning device. Generally, only positioning marks are set, and workers have to manually adjust the zirconia ceramic blocks to place them in the appropriate printing position. This makes it easy for some zirconia ceramic blocks to be positioned inaccurately, affecting the printing quality. Furthermore, when printing zirconia ceramic blocks in batches, some zirconia ceramic blocks need to be adjusted multiple times to find the correct position, which reduces work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a zirconia ceramic block surface printing positioning device to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model provides a zirconia ceramic block surface printing positioning device, comprising: a positioning base, with a plurality of receiving grooves evenly spaced on the upper surface of the positioning base for accommodating the zirconia ceramic block;

[0006] The positioning part is provided at equal intervals on the positioning base, and the positioning part corresponds one-to-one with the receiving groove.

[0007] A top support is installed inside the positioning base and is used to simultaneously lift several zirconia ceramic blocks in the receiving grooves.

[0008] A driving unit is disposed within the positioning base, and the driving unit is used to drive a plurality of the positioning units and engage with the top support unit.

[0009] A guide portion is disposed on the positioning base and the driving portion, and the guide portion is used to support and stabilize the driving portion;

[0010] The depth of the receiving groove is less than the height of the zirconia ceramic block, and the diameter of the receiving groove is greater than the diameter of the zirconia ceramic block.

[0011] The driving unit is driven, and several positioning units move closer to or further away from the zirconia ceramic blocks in the corresponding receiving grooves. When the positioning units move away from the zirconia ceramic blocks, the top support unit rotates and lifts the zirconia ceramic blocks.

[0012] Furthermore, the positioning part includes several movable slots formed on the positioning base and symmetrically arranged on both sides of the receiving groove, two first positioning rods and two second positioning rods disposed in the several movable slots, and several positioning rings rotatably mounted on the two first positioning rods and the two second positioning rods.

[0013] Furthermore, the top support includes a plurality of control rods rotatably mounted in the positioning base, a plurality of control gears fixedly sleeved on the plurality of control rods and movably mounted in the positioning base, a plurality of placement grooves respectively opened at the bottom of the plurality of receiving grooves, and a plurality of lifting members fixed on the plurality of control rods and respectively disposed in the plurality of placement grooves.

[0014] The lifting component includes two lifting rods that are fixedly connected to the control rod.

[0015] Furthermore, the drive unit includes a control cavity formed within the positioning base, and a first push frame and a second push frame slidably mounted within the control cavity;

[0016] A number of the first positioning rods and a number of the second positioning rods are respectively fixed on the first push frame and the second push frame.

[0017] Furthermore, the drive unit also includes a transmission gear rotatably mounted in the control cavity, two transmission racks respectively fixed on the first push frame and the second push frame and meshing with the transmission gear, and two electric push rods symmetrically mounted in the control cavity;

[0018] The telescopic ends of both electric push rods are fixedly connected to the second push frame.

[0019] Furthermore, the drive unit also includes a transmission cavity formed within the positioning base and communicating with the control cavity, a control rack slidably mounted within the transmission cavity and meshing with a plurality of control gears, a first abutment and a second abutment respectively fixedly connected to the second push frame and the control gears, and two return springs fixedly connected at one end to the second abutment and at the other end to the inner wall of the transmission cavity.

[0020] Furthermore, the guide portion includes a plurality of ball grooves formed at the bottom of the first push frame and the second push frame, a plurality of guide balls movably installed in the plurality of ball grooves, and a plurality of guide slots formed at the bottom of the control cavity for the movement of the plurality of guide balls.

[0021] Compared with the prior art, the embodiments of this utility model have the following beneficial effects:

[0022] This zirconia ceramic block surface printing positioning device places several zirconia ceramic blocks in several receiving slots, and under the control of the drive unit, simultaneously clamps and positions the zirconia ceramic blocks in the several receiving slots to ensure the positioning accuracy of the zirconia ceramic blocks, prevents the zirconia ceramic blocks to be printed from moving slightly, ensures the printing effect, and eliminates the need for manual repeated adjustment of the placement position of the zirconia ceramic blocks during use, reducing the workload of the staff.

[0023] This zirconia ceramic block surface printing positioning device, after the zirconia ceramic block printing is completed, drives several positioning parts to release the clamping and positioning of several zirconia ceramic blocks. At the same time, the top support part is driven to work, so that the zirconia ceramic blocks in several receiving slots are all lifted up. This avoids the problem of zirconia ceramic blocks being inconvenient to workers to pick up when they are in the receiving slots. It makes it convenient for workers to quickly remove the zirconia ceramic blocks from the positioning device. When placing the next batch of zirconia, the several receiving slots provide a reference position for the placement of several zirconia ceramic blocks. With the support effect of several top supports, the zirconia ceramic blocks do not need to be completely placed into the receiving slots when placing them, which greatly shortens the placement time of the zirconia ceramic blocks and improves work efficiency.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0036] like Figure 1-8 As shown, a zirconia ceramic block surface printing positioning device includes: a positioning base 1, and several receiving grooves 2 that are equally spaced on the upper surface of the positioning base 1 and used to place the zirconia ceramic block.

[0037] Positioning parts 3 are arranged at equal intervals on the positioning base 1, and each of the positioning parts 3 corresponds to one of the receiving grooves 2.

[0038] Top support 4 is installed in the positioning base 1 and is used to simultaneously lift a number of zirconium oxide ceramic blocks in the receiving groove 2.

[0039] The driving unit 5 is disposed in the positioning base 1 and is used to drive a plurality of the positioning units 3 and engage the transmission of the top support unit 4.

[0040] A guide portion 6 is disposed on the positioning base 1 and the driving portion 5, and the guide portion 6 is used to support and stabilize the driving portion 5;

[0041] The depth of the receiving groove 2 is less than the height of the zirconia ceramic block, and the diameter of the receiving groove 2 is greater than the diameter of the zirconia ceramic block.

[0042] Drive the drive unit 5, and several positioning units 3 move closer to or further away from the zirconia ceramic block in the corresponding receiving groove 2. When the positioning unit 3 moves away from the zirconia ceramic block, the top support unit 4 rotates and lifts the zirconia ceramic block.

[0043] When in use, the positioning device is placed on the printing table of the zirconia ceramic block. At this time, the top support 4 is driven by the drive unit 5 and is in the top support state. Then, multiple zirconia ceramic blocks can be placed one by one into several receiving slots 2 and supported by the top support 4. Since the diameter of the receiving slot 2 is larger than the diameter of the zirconia ceramic block, the zirconia ceramic block can be placed in the receiving slot 2 quickly and independently without the need for manual adjustment of the placement position of the zirconia ceramic block.

[0044] Next, the drive unit 5 operates, and the two first positioning rods 8 and two second positioning rods 9 corresponding to the several receiving grooves 2 are controlled to move closer to each other. During the process of the two first positioning rods 8 and two second positioning rods 9 moving closer to each other in the several receiving grooves 2, the top support 4 is controlled by the drive unit 5, so that the several lifting parts 14 in the top support 4 are respectively stored in the placement grooves 13 at the bottom of the several receiving grooves 2. The several zirconia ceramic blocks are completely placed in the several receiving grooves 2, ensuring that the two first positioning rods 8 and two second positioning rods 9 in the several receiving grooves 2 can effectively contact and position the corresponding zirconia ceramic blocks, and complete the stable clamping and positioning of the several zirconia ceramic blocks by the several positioning units 3, ensuring the positioning accuracy of the zirconia ceramic blocks. Furthermore, since the depth of the receiving groove 2 is less than the height of the zirconia ceramic block, the top of the zirconia ceramic block can smoothly contact the printing equipment for printing operations, effectively avoiding the problem of pattern displacement caused by the easy rotation of round products when printing zirconia ceramic blocks, resulting in misalignment of different colors.

[0045] After several zirconia ceramic blocks have been printed, the drive unit 5 operates, and the two first positioning rods 8 and two second positioning rods 9 in the several receiving grooves 2 are controlled to move away from each other, releasing the clamping and positioning of the zirconia ceramic blocks. At the same time, the top support unit 4 is controlled to lift the zirconia ceramic blocks in the several receiving grooves 2 simultaneously, so that the workers can quickly take out the zirconia ceramic blocks from the several receiving grooves 2, and then place and position the next batch of zirconia ceramic blocks. This greatly shortens the time for picking up and putting away zirconia ceramic blocks, reduces the workload of the workers, and ensures the printing and processing efficiency of zirconia ceramic blocks.

[0046] Optionally, the positioning part 3 includes several movable grooves 7 formed on the positioning base 1 and symmetrically arranged on both sides of the receiving groove 2, two first positioning rods 8 and two second positioning rods 9 disposed in the several movable grooves 7, and several positioning rings 10 rotatably mounted on the two first positioning rods 8 and the two second positioning rods 9. When several zirconia ceramic blocks are placed into the several receiving grooves 2, the two first positioning rods 8 and the two second positioning rods 9 in the several receiving grooves 2 approach each other to clamp and position the zirconia ceramic blocks, and the two first positioning rods 8 and 9... Positioning rings 10 are rotatably connected to rod 8 and the two second positioning rods 9, so that when the first positioning rod 8 and the second positioning rod 9 are clamped with the zirconia ceramic block, rolling friction is formed between the first positioning rod 8 and the second positioning rod 9 and the zirconia ceramic block, which significantly reduces the friction force, avoids scratching or damaging the surface of the zirconia ceramic block, facilitates the movement of the zirconia ceramic block, and ensures that the positioning rings 10 on the two first positioning rods 8 and the two second positioning rods 9 are in contact with the zirconia ceramic block, ensuring that the zirconia ceramic block is located in the middle of the receiving groove 2, and ensuring the clamping and positioning stability of the zirconia ceramic block.

[0047] Optionally, the top support 4 includes a plurality of control rods 11 rotatably mounted in the positioning base 1, a plurality of control gears 12 fixedly sleeved on the plurality of control rods 11 and movably mounted in the positioning base 1, a plurality of placement grooves 13 respectively opened at the bottom of the plurality of receiving grooves 2, and a plurality of lifting members 14 fixed on the plurality of control rods 11 and respectively disposed in the plurality of placement grooves 13.

[0048] The lifting component 14 includes two lifting rods 15 fixedly connected to the control rod 11. The two first positioning rods 8 and the two second positioning rods 9 in the plurality of receiving grooves 2 are all far apart from each other. When the clamping of the zirconium oxide in the receiving groove 2 is released, the plurality of control gears 12 are all meshed and driven by the drive unit 5 to rotate, thereby causing the plurality of control rods 11 to rotate synchronously, so that the plurality of lifting components 14 respectively lift the zirconium oxide ceramic blocks in the plurality of receiving grooves 2. At the same time, the lifting component is composed of two lifting rods 15 symmetrically arranged in the receiving groove 2, and there is a certain amount of space between the two lifting rods 15, so as to facilitate the staff to insert their fingers into the space to quickly pick up and put away the zirconium oxide ceramic blocks.

[0049] During the process of positioning the zirconia ceramic block in the receiving groove 2 by the positioning part 3, several control gears 12 are meshed and driven by the drive part 5 to rotate, thereby causing several control rods 11 to rotate synchronously, so that several lifting parts 14 are respectively stored in the placement grooves 13 in several receiving grooves 2, so as to avoid affecting the clamping and positioning effect of the zirconia ceramic block.

[0050] Optionally, the drive unit 5 includes a control cavity 16 formed in the positioning base 1, and a first push frame 17 and a second push frame 18 slidably mounted in the control cavity 16;

[0051] A number of first positioning rods 8 and a number of second positioning rods 9 are respectively fixed on the first push frame 17 and the second push frame 18. In use, the first push frame 17 and the second push frame 18 can respectively drive the number of first positioning rods 8 and the number of second positioning rods 9 to move. Thus, when the first push frame 17 and the second push frame 18 move synchronously, the corresponding first positioning rods 8 and second positioning rods 9 in the number of receiving grooves 2 can move synchronously, approaching or moving away from each other, thereby clamping, positioning and releasing the zirconia ceramic block placed in the receiving groove 2.

[0052] Optionally, the drive unit 5 further includes a transmission gear 19 rotatably mounted in the control cavity 16, two transmission racks 20 respectively fixed on the first push frame 17 and the second push frame 18 and meshing with the transmission gear 19, and two electric push rods 21 symmetrically mounted in the control cavity 16;

[0053] The telescopic ends of both electric push rods 21 are fixedly connected to the second push frame 18. In use, the two electric push rods 21 work synchronously, which can drive the second push frame 18 to move in the control cavity 16. Under the meshing transmission of the transmission gear 19 and the two transmission racks 20, the first push frame 17 and the second push frame 18 move synchronously, and the first push frame 17 and the second push frame 18 move in opposite directions, ensuring the synchronicity of the movement of the first push frame 17 and the second push frame 18.

[0054] Optionally, the drive unit 5 further includes a transmission cavity 22 formed in the positioning base 1 and connected to the control cavity 16, a control rack 23 slidably installed in the transmission cavity 22 and meshing with a plurality of control gears 12, a first abutment 24 and a second abutment 25 respectively fixedly connected to the second push frame 18 and the control gears 12 and movably disposed in the transmission cavity 22, and two return springs 26 with one end fixedly connected to the second abutment 25 and the other end fixedly connected to the inner wall of the transmission cavity 22;

[0055] When the second push frame 18 is controlled by two electric push rods 21 to move horizontally in the control cavity 16, the two first positioning rods 8 and the two second positioning rods 9 in the plurality of receiving slots 2 move away from each other. When the clamping and positioning of the zirconia ceramic block is released, the first abutment rod 24 on the second push frame 18 abuts and pushes the second abutment rod 25 to compress the two return springs 26, and drives the control rack 23 to move in the transmission cavity 22, meshing and driving the rotation of the plurality of control gears 12, thereby controlling the plurality of lifting parts 14 to lift part of the zirconia ceramic block in the plurality of receiving slots 2, so as to facilitate the workers to pick up and put down the zirconia ceramic block;

[0056] Furthermore, when the two first positioning rods 8 and the two second positioning rods 9 complete the clamping and positioning of the zirconia ceramic block, there is a certain amount of space between the first abutment rod 24 and the second abutment rod 25. Thus, when the zirconia ceramic block is placed in the receiving groove 2, and the two first positioning rods 8 and the two second positioning rods 9 approach each other to clamp and position the zirconia ceramic block, the two first positioning rods 8 and the two second positioning rods 9 move a certain distance, but before the clamping and positioning of the zirconia ceramic block is completed, the control rack 23 can be reset under the elastic force of the return spring 26, and the meshing transmission of several control gears 12 can be rotated, releasing the lifting of the zirconia ceramic block, making it convenient for the first positioning rods 8 and the two second positioning rods 9 to clamp and position the zirconia ceramic block.

[0057] Achieving two functions with a single drive reduces the complexity of the mechanical structure, effectively reduces the overall size of the positioning device, facilitates its use on printing equipment, and ensures the synchronization of clamping, positioning, and lifting of the zirconia block, avoiding errors caused by coordination issues between multiple drives.

[0058] Optionally, the guide portion 6 includes a plurality of ball grooves 27 formed at the bottom of the first push frame 17 and the second push frame 18, a plurality of guide balls 28 respectively movably installed in the plurality of ball grooves 27, and a plurality of guide grooves 29 formed at the bottom of the control cavity 16 for the plurality of guide balls 28 to move. When the first push frame 17 and the second push frame 18 move in the control cavity 16, the plurality of guide balls 28 rotate in the plurality of ball grooves 27 and move in the plurality of guide grooves 29, thereby effectively reducing the friction between the first push frame 17 and the second push frame 18 and the inner wall of the control cavity 16, and ensuring the stability and smooth movement of the first push frame 17 and the second push frame 18 in the control cavity 16.

[0059] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
