Description

Technical Field

[0001] The utility model relates to the technical field of glass device manufacturing, and particularly relates to a glass device processing tooling, a lathe and a glass device. Background Art

[0002] In electro-vacuum glass devices, many components need to seal glass and metal together. The most commonly used metal for sealing in the electronic glass devices we make is kovar. After kovar is sealed with glass, the strength and airtightness need to be ensured. Currently, the sealing of the glass tube and the kovar part is carried out by clamping with a fixture on a lathe and then flame heating. The kovar part and the glass tube are fixed on the fixture by means of screw fastening. This method requires manual tightening of the setscrew and adjustment of the concentricity of the parts, which is time-consuming and requires relatively high skills to properly install the materials. Moreover, when using the screw fastening method for clamping, the threads expand when heated by the flame and deform when cooled, resulting in inability to disassemble. In addition, directly tightening the kovar part and the glass tube with a setscrew easily damages the kovar part and the glass tube. Summary of the Utility Model

[0033] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0034] The terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data may be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same category, and the number of objects is not limited. For example, the first object may be one or multiple. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / " generally means an "or" relationship between the associated objects before and after.

[0035] Next, in conjunction with the accompanying drawings, the present application provided by some embodiments and their application scenarios will be described in detail.

[0036] Generally, two fixtures are provided on a glass processing lathe, which are respectively used for installing a glass tube and a kovar. During sealing, the parts of the glass tube and the kovar to be sealed are brought close to each other by moving the fixtures, and then the sealing parts are heated with a flame to melt the glass tube and connect it to the kovar. The present application mainly improves the structure of the fixtures.

[0037] See Figures 1 to 3 As shown, an embodiment of the present application provides a glass device processing tooling, including:

[0038] A fixture 1, on which a groove 11 for placing a glass tube / kovar part is provided; in a cooled state, after the glass tube / kovar part is placed in the groove 11, there is a gap between the groove 11 and the glass tube / kovar part, and the size of the gap is slightly smaller than or equal to the size increased after the glass tube / kovar part expands due to heat.

[0039] Among them, the shape of the groove 11 is adapted to the shape of the glass tube / kovar part. For example, if the glass tube / kovar part is cylindrical or prismatic, the groove 11 is also cylindrical or prismatic. Taking the cylindrical shape as an example, as Figure 1 shown, in the cooled state, the inner diameter dimension of the groove 11 is close to the outer diameter dimension of the glass tube / kovar part. After the glass tube / kovar part is placed in the groove 11, there is a small gap between the groove 11 and the glass tube / kovar part. This gap provides a margin for the thermal expansion of the glass tube / kovar part and also ensures that the glass tube / kovar part will not easily fall off when installed in the groove. During the sealing process, the glass tube / kovar part is heated by a flame, which can cause the glass tube / kovar part to expand thermally. Since the gap between the groove 11 and the glass tube / kovar part is slightly smaller than or equal to the increased dimension of the glass tube / kovar part after thermal expansion, the glass tube / kovar part will fill the gap and abut against the edge of the groove 11 to achieve fastening after thermal expansion. After sealing, the flame is stopped, and the glass tube / kovar part can be removed from the groove 11 after waiting for it to cool.

[0040] This application is dedicated to solving the problems that when using a threaded fastener for the fixture of the glass tube and the kovar part, thermal expansion deformation and non-detachability may occur, reducing the operation difficulty and improving the product quality. This application does not require any threaded fasteners and only clamps the glass tube or kovar part by relying on the characteristics of thermal expansion and contraction of the parts, which not only saves the time for clamping and disassembling, but also effectively controls the non-detachability caused by the thermal deformation of the tooling, and can also well ensure that the glass tube or kovar part will not be damaged, improving the product quality.

[0041] Optionally, the size of the gap is less than or equal to 0.1 mm. At this time, this gap provides a margin for the thermal expansion of the glass tube / kovar part and also ensures that the glass tube / kovar part will not easily fall off when installed in the groove. During the sealing process, the glass tube / kovar part is heated by a flame, and the glass tube / kovar part will fill the gap and abut against the edge of the groove 11 to achieve fastening after thermal expansion.

[0042] Preferably, the size of the gap is less than or equal to 0.05 mm. At this time, further reducing the size of the gap can further reduce the risk of the glass tube / kovar part falling off when installed in the groove and improve the firmness of fastening.

[0043] Since the glass tube / kovar part needs to be continuously heated by a flame during the processing, inevitably, the fixture 1 will also be baked by the flame. If the fixture 1 expands thermally, it may cause the glass tube / kovar part to fall out of the tooling, affecting the product processing.

[0044] To avoid this problem, continue to refer to Figure 1, Preferably, the glass device processing tooling further includes a circulation pipe 2 surrounding the fixture 1, and the circulation pipe 2 is used for the coolant to flow in a single direction; the coolant includes water.

[0045] At this time, by winding a circulation pipe 2 capable of continuously flowing coolant outside the fixture 1, the temperature of the fixture 1 can be reduced, and the influence of the thermal expansion of the fixture 1 on processing is avoided.

[0046] Preferably, the circulation pipe 2 includes a first input end 22, a first output end 21, and a pipe body 23 surrounding the fixture 1; the first input end 22 is communicated with the second output end of the refrigerator for inputting the coolant produced by the refrigerator into the pipe body 23; the first output end 21 is communicated with the second input end of the refrigerator for conveying the coolant flowing through the pipe body 23 back to the refrigerator.

[0047] At this time, the refrigerator can continuously produce coolant. The coolant is input from the first input end 22 into the pipe body 23 surrounding the fixture 1, and after heat exchange around the whole body of the fixture 1, it is conveyed back to the refrigerator from the first output end 21, thereby realizing circulating refrigeration.

[0048] Preferably, the fixture 1 is further provided with a connecting rod 12 for connecting with the lathe 4. One end of the connecting rod 12 is connected with the groove 11, and the other end extends in the direction opposite to the groove 11. At this time, the fixture 1 can be fixed to the lathe 4 through the connecting rod 12 to realize the processing of the glass device.

[0049] Wherein, both the first input end 22 and the first output end 21 are arranged at one end of the connecting rod 12 away from the groove 11. At this time, the first input end 22 and the first output end 21 are arranged at the same end, so that two ports can be designed at one end for connecting with the refrigerator, which simplifies the design structure and improves the convenience of installation and disassembly.

[0050] Wherein, the pipe body 23 starts from the first input end 22, surrounds the connecting rod 12 to the end where the groove 11 is located, and then reversely surrounds the connecting rod 12 along the end where the groove 11 is located to the first output end 21 to end. At this time, the pipe body 23 is tightly wound around the fixture 1, and the temperature reduction of the fixture 1 can be realized.

[0051] Wherein, the pipe body 23 can only surround the connecting rod 12. At this time, the end where the groove 11 is located refers to the end of the connecting rod 12 close to the groove 11; or when the pipe body 23 surrounds the connecting rod 12, it can also surround the groove 11. At this time, the end where the groove 11 is located refers to the end of the groove 11 close to the connecting rod 12 or the other end away from the connecting rod 12. The larger the area where the pipe body 23 winds around the fixture 1, the better the heat exchange effect and the better the temperature reduction effect, but the structure is more complex and the processing difficulty increases. It can be actually selected according to requirements.

[0052] During the processing of the glass tube / kovar parts, the fixture 1 rotates synchronously with the glass tube / kovar parts, while the refrigerator needs to remain fixed and cannot rotate. If the refrigerator is only connected to the other end of the circulation pipe 2, the connection part between the circulation pipe 2 and the refrigerator rotates at one end following the fixture 1 and is fixed at the other end, so they will be twisted together, affecting the use. To solve this problem, the present application adopts a rotary joint 3 to ensure that the coolant can circulate smoothly while the circulation pipe 2 rotates synchronously with the fixture 1. The following is a detailed introduction.

[0053] Preferably, as Figures 1 - 2 shown, the glass device processing tooling further includes:

[0054] A rotary joint 3 is arranged between the refrigerator and the circulation pipe 2. The rotary joint 3 includes a rotating part 31 and a fixed part 32. The rotating part 31 can rotate synchronously with the fixture 1 and the circulation pipe 2, and the fixed part 32 remains stationary when the fixture 1 and the circulation pipe 2 rotate;

[0055] As Figure 3 shown, the rotating part 31 includes a first rotating guiding pipe 312 connected to the first input end 22, and the fixed part 32 includes a first fixed guiding pipe 322 connected to the second output end. When the first rotating guiding pipe 312 rotates synchronously with the fixture 1 and the circulation pipe 2, it always remains in communication with the first fixed guiding pipe 322, and the coolant produced by the refrigerator can be transported to the pipe body 23 through the first fixed guiding pipe 322 and the first rotating guiding pipe 312;

[0056] The rotating part 31 includes a second rotating guiding pipe 311 connected to the first output end 21, and the fixed part 32 includes a second fixed guiding pipe 321 connected to the second input end. When the second rotating guiding pipe 311 rotates synchronously with the fixture 1 and the circulation pipe 2, it always remains in communication with the second fixed guiding pipe 321, and the coolant flowing through the pipe body 23 can be transported back to the refrigerator through the second fixed guiding pipe 321 and the second rotating guiding pipe 311.

[0057] At this time, a rotary joint 3 is added between the circulation pipe 2 and the refrigerator. Through the rotary joint 3, when the circulation pipe 2 rotates and the refrigerator remains stationary, there will be no interference between them, and the connection state between the circulation pipe 2 and the refrigerator is always maintained, ensuring the effective operation of the circulating refrigeration of the fixture 1. Among them, the rotary joint 3 is divided into a rotating part 31 and a fixed part 32. The rotating part 31 can rotate with the circulation pipe 2, and the fixed part 32 remains stationary when the rotating part 31 rotates, without interference between them. The rotating part 31 is connected to the first input end 22 of the circulation pipe 2 through the first rotating guiding pipe 312, and the fixed part 32 is connected to the second output end of the refrigerator through the first fixed guiding pipe 322. When the first rotating guiding pipe 312 rotates with the circulation pipe 2, it always remains connected to the first fixed guiding pipe 322. In this way, the second output end of the refrigerator and the first input end 22 of the circulation pipe 2 also always remain connected, and the coolant can be smoothly transported to the circulation pipe 2.

[0058] The rotating part 31 is connected to the first output end 21 of the circulation pipe 2 through the second rotating guiding pipe 311, and the fixed part 32 is connected to the second input end of the refrigerator through the second fixed guiding pipe 321. When the second rotating guiding pipe 311 rotates with the circulation pipe 2, it always remains connected to the second fixed guiding pipe 321. In this way, the second input end of the refrigerator and the first output end 21 of the circulation pipe 2 also always remain connected, and the coolant that has absorbed heat can be smoothly transported back to the refrigerator for recycling.

[0059] Preferably, the fixed part 32 further includes a first water collecting tank 52 and a second water collecting tank 51;

[0060] The first rotating guiding pipe 312 includes a first pipe orifice 312A and a second pipe orifice 312B. The first pipe orifice 312A is connected to the first input end 22, and the second pipe orifice 312B always faces the orifice of the first water collecting tank 52 during the rotation of the rotating part 31 with the fixture 1 and the circulation pipe 2; the first fixed guiding pipe 322 includes a third pipe orifice 322A and a fourth pipe orifice 322B. The third pipe orifice 322A communicates with the first water collecting tank 52, and the fourth pipe orifice 322B is connected to the second output end;

[0061] The second rotating guiding pipe 311 includes a fifth pipe orifice 311A and a sixth pipe orifice 311B. The fifth pipe orifice 311A is connected to the first output end, and the sixth pipe orifice 311B always faces the orifice of the second water collecting tank 51 during the rotation of the rotating part 31 with the fixture 1 and the circulation pipe 2; the second fixed guiding pipe 321 includes a seventh pipe orifice 321A and an eighth pipe orifice 321B. The seventh pipe orifice 321A communicates with the second water collecting tank 51, and the eighth pipe orifice 321B is connected to the second input end.

[0062] At this time, by providing a first water collecting tank 52 on the fixed part 32, the first water collecting tank 52 is communicated with the first fixed guiding pipe 322, and the first rotating guiding pipe 312 always faces the notch of the first water collecting tank 52 during rotation, which can ensure that the first rotating guiding pipe 312 is always communicated with the first fixed guiding pipe 322, so that the coolant output from the refrigerator can smoothly enter the circulation pipe 2. Similarly, by providing a second water collecting tank 51 on the fixed part 32, the second water collecting tank 51 is communicated with the second fixed guiding pipe 321, and the second rotating guiding pipe 311 always faces the notch of the second water collecting tank 51 during rotation, which can ensure that the second rotating guiding pipe 311 is always communicated with the second fixed guiding pipe 321, so that the coolant passing through the circulation pipe 2 can smoothly return to the refrigerator to realize cycle refrigeration.

[0063] Specifically, the coolant output from the refrigerator first enters the first fixed guiding pipe 322 from the second output end and the fourth pipe orifice 322B, then enters the first water collecting tank 52 from the third pipe orifice 322A, then enters the first rotating guiding pipe 312 from the notch of the first water collecting tank 52 and the second pipe orifice 312B, and finally enters the pipe body 23 of the circulation pipe 2 from the first pipe orifice 312A and the first input end 22. After the coolant exchanges heat through the pipe body 23, the temperature of the fixture 1 is reduced. The coolant that has absorbed the heat of the fixture 1 enters the second rotating guiding pipe 311 from the first output end 21 and the fifth pipe orifice 311A, then enters the second water collecting tank 51 from the sixth pipe orifice 311B, then enters the second fixed guiding pipe 321 from the second water collecting tank 51 and the seventh pipe orifice 321A, and finally returns to the refrigerator from the eighth pipe orifice 321B and the second input end to realize cycle refrigeration.

[0064] Preferably, as Figure 3 shown, the rotating part 31 includes a protruding structure 31A, the fixed part 32 includes a concave structure 32A, the protruding structure 31A extends into the concave structure 32A, and the outer side wall of the protruding structure 31A faces the inner side wall of the concave structure 32A; the second pipe orifice 312B and the sixth pipe orifice 311B are provided on the outer side wall of the protruding structure 31A, and the first water collecting tank 52 and the second water collecting tank 51 are annular grooves provided on the inner side wall of the concave structure 32A.

[0065] At this time, the outer side wall of the protruding structure 31A faces the inner side wall of the concave structure 32A, the second pipe orifice 312B is provided on the outer side wall of the protruding structure 31A and always faces the first water collecting tank 52 on the inner side wall of the concave structure 32A; the sixth pipe orifice 311B is provided on the outer side wall of the protruding structure 31A and always faces the second water collecting tank 51 on the inner side wall of the concave structure 32A.

[0066] Preferably, the first pipe orifice 312A and the fifth pipe orifice 311A are arranged on the upper end surface of the rotating part 31 away from the protruding structure 31A, and the fourth pipe orifice 322B and the eighth pipe orifice 321B are arranged on the lower end surface of the fixed part 32 away from the concave structure 32A.

[0067] Preferably, the second pipe orifice 312B and the sixth pipe orifice 311B are arranged in opposite directions and have different heights on the outer side wall of the protruding structure 31A; the first water collecting tank 52 and the second water collecting tank 51 are arranged corresponding to the positions of the second pipe orifice 312B and the sixth pipe orifice 311B respectively.

[0068] At this time, the guiding paths formed by the first rotating guiding pipe 312, the first water collecting tank 52, and the first fixed guiding pipe 322, and the guiding paths formed by the second rotating guiding pipe 311, the second water collecting tank 51, and the second fixed guiding pipe 321 do not interfere with each other, ensuring normal operation.

[0069] Optionally, the second rotating guiding pipe 311 is shorter than the first rotating guiding pipe 312, the second pipe orifice 312B and the sixth pipe orifice 311B are arranged in opposite directions, and the sixth pipe orifice 311B is above the second pipe orifice 312B. However, it is not limited thereto.

[0070] Preferably, as Figure 2 shown, the first input end 22 passes through the lathe 4 and is connected to the first pipe orifice 312A; the first output end 21 passes through the lathe 4 and is connected to the fifth pipe orifice 311A.

[0071] At this time, the fixture 1 and the circulating pipe 2 thereon are arranged on one side of the lathe 4 for sealing the glass tube / kovar part, and the rotary joint 3 and the refrigerator are arranged on the other side of the lathe, avoiding interference with the sealing work.

[0072] Specifically, the lathe 4 may include a main shaft 41 and a three-jaw chuck 42. The connecting rod 12 on the fixture 1 can extend into the three-jaw chuck 42 and be connected to the main shaft 41, and the fixture 1 can be tightened and fixed by the three-jaw chuck 42. The first input end 22 and the first output end 21 of the circulating pipe 2 can pass through the main shaft 41 on the lathe 4 and then be connected to the rotary joint 3.

[0073] In this application, the fixture 1, the circulating pipe 2, and the rotary joint 3 can be processed by metal, and it is best to be able to withstand high-temperature baking.

[0074] The following is a specific application example described as follows.

[0075] When the equipment is in use, as Figures 2 - 3As shown, first install the rotary joint 3 on the glass lathe 4, and connect the circulation pipe 2 to the rotary joint 3, wherein the first pipe opening 312A of the first rotary guide pipe 312 of the rotating part 31 is connected to the first input end 22 of the circulation pipe 2, the fifth pipe opening 311A ​​of the second rotary guide pipe 311 of the rotating part 31 is connected to the first output end 21 of the circulation pipe 2, the fourth pipe opening 322B of the first fixed guide pipe 322 is connected to the second output end of the water cooler, and the eighth pipe opening 321B of the second fixed guide pipe 321 is connected to the first input end of the water cooler. Note that the connection is tight and no leakage should occur. Then connect the circulation pipe 2 with the fixture 1, and then clamp the fixture 1 to the three-jaw chuck of the lathe, and then install the glass tube / kovar part into the groove 11 of the fixture 1. Since the outer diameter of the glass tube / kovar part is close to the inner diameter of the groove 11 of the fixture 1, the glass tube / kovar part can be stuck in the groove 11 and will not fall off easily, but there is still a gap between the two. After installation, start firing. The glass tube / kovar part is heated by flame, which can make the glass tube / kovar part expand due to heat and hit the edge of the groove 11 for tightening. After sealing, stop the flame and wait for the product to cool down before removing the product. In the process, the cooling liquid (such as cold water) generated by the refrigerator is injected into the first fixed guide pipe 322 from the fourth pipe port 322B, and enters the first water collecting tank 52 from the first fixed guide pipe 322, and then enters the first rotating guide pipe 312 from the notch of the first water collecting tank 52 and the second pipe port 312B, and enters the circulation pipe 2 surrounding the fixture 1 from the first pipe port 312A and the first input end 22 through the first rotating guide pipe 312. After the cooling liquid passes through the fixture 1, the temperature of the fixture 1 is reduced through heat exchange, and no thermal expansion occurs. The heated cooling liquid flows out from the first output end 21 to the fifth pipe port 311A, enters the groove of the second water collecting tank 51 through the second rotating guide pipe 311 and the sixth pipe port 311B, and then enters the second fixed guide pipe 321 from the seventh pipe port 321A, and finally enters the refrigerator from the eighth pipe port 321B to be cooled again.

[0076] In the present application, the rotary joint 3 can be permanently installed in the glass lathe 4, and when replacing the tooling, it is only necessary to remove the circulation pipe 2 and the fixture 1.

[0077] This application uses circulating water to cool the tooling, and through the characteristics of metal thermal expansion and contraction, it can clamp the product parts, ensuring that the product will not be damaged by the expansion of the tooling during the processing, thereby ensuring the processing accuracy of the product. Product processing needs to be completed on a glass lathe. During the processing, the lathe and the product are rotating all the time, so the tooling and water channel must also rotate synchronously. After realizing this function, it can be ensured that the product can be processed smoothly. It is difficult for traditional tooling fixtures to achieve this function.

[0078] The embodiment of the present application also provides a lathe for processing glass devices, including: the glass device processing tooling as described above.
