Description

Technical Field

[0001] The invention belongs to the technical field of electron tube glass shells, and in particular relates to a preparation method and a structure of a novel electron tube glass shell. Background Art

[0002] As an important component of electron tubes, the development history of electron tube glass shells is closely linked to the evolution of electron tube technology. Since the birth of electron tubes, glass shells have existed as key components to protect the internal structure of electron tubes and maintain the vacuum state. With the continuous development of electronic technology, the materials, processes and performance of electron tube glass shells are also constantly improving and upgrading. From the initial simple glass containers to today's advanced glass shells with high precision, high pressure resistance, high vacuum and other characteristics, the technological progress of electron tube glass shells has provided a strong guarantee for the application of electron tubes.

[0003] However, existing glass materials are sensitive to temperature changes, especially in the process of rapid heating and cooling, the temperature difference between the inside and outside of the glass shell will cause thermal stress. If this thermal stress exceeds the bearing limit of the glass shell material, it will cause the glass shell to crack or be damaged. When the glass shell is exposed to a rapidly changing temperature environment, such as rapidly transferring from a low temperature environment to a high temperature environment, or vice versa, the temperature difference between the inside and outside of the glass shell will cause uneven distribution of thermal stress, resulting in cracks or ruptures in the weak parts of the glass shell, so it is necessary for staff to improve it. Summary of the invention

[0004] The object of the present invention is to provide a novel method for preparing a glass shell of an electron tube and a structure thereof, so as to solve the problems raised in the above background technology.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1:

[0036] See also Figure 1 As shown, a method for preparing a novel electron tube glass shell comprises the following steps:

[0037] S1. Material selection and pretreatment;

[0038] S2, forming and processing;

[0039] S3, vacuum treatment and packaging;

[0040] S4, special process treatment;

[0041] S5. Quality inspection and testing.

[0042] In step S1, the material is selected to have good vacuum holding ability and thermal stress resistance to adapt to the changes in the working environment of the electron tube. The glass raw materials are strictly screened and cleaned to remove impurities and pollutants, and the glass raw materials are pre-treated by high-temperature baking and other processes.

[0043] Introduce more specific material screening criteria, such as selecting glass materials with high heat resistance and low expansion coefficient, such as borosilicate glass, selecting borosilicate glass with good vacuum holding ability and high resistance to thermal stress as raw materials, conduct strict screening and cleaning to remove all visible impurities and contaminants, and further purify the glass raw materials through high-temperature baking to remove internal moisture and volatile impurities.

[0044] Borosilicate glass with high heat resistance and low expansion coefficient is the first choice. This material not only has good vacuum retention ability, can maintain a high vacuum state inside under extreme working environments, reduce interference and noise between electronic components, but also exhibits excellent thermal stress resistance, effectively resisting thermal stress cracking or damage caused by temperature changes.

[0045] In order to ensure the purity of the raw materials, multiple screening and cleaning processes are adopted. First, large impurities and particles are removed through a precision screen; then, an ultrasonic cleaner is used in combination with deionized water for deep cleaning to thoroughly remove tiny impurities and contaminants attached to the surface of the glass raw materials. In addition, a high-temperature baking process is introduced, in which the glass raw materials are placed in a constant temperature furnace and baked at a specific temperature for several hours to remove residual moisture and volatile impurities inside, further purify the raw materials, and lay a solid foundation for subsequent molding processing.

[0046] In step S2, the pre-treated glass raw material is processed into a glass bulb of a desired shape by using one of the precision blowing method, the pressing method and the drawing method, and the formed glass bulb is subjected to a series of processing such as precise cutting, edge grinding and punching.

[0047] By precisely controlling the air pressure and temperature during the blowing process, the pre-treated glass raw materials are processed into irregular cylindrical glass bulbs of the required shape. Subsequently, the glass bulbs are finely processed using high-precision cutting and edge grinding equipment to ensure smooth and flawless edges, and precise holes are punched to meet the installation requirements of electronic components.

[0048] Using advanced precision blowing method, the pre-treated borosilicate glass raw materials are processed into irregular cylindrical glass shells of the required shape by precisely controlling the air pressure, temperature and fluidity of the glass liquid during the blowing process. This unique shape not only improves the heat dissipation efficiency of the electron tube, but also increases the flexibility of installation to meet diverse usage needs.

[0049] After forming, the glass bulb needs to be processed carefully to ensure it is flawless. High-precision cutting and edge grinding equipment is used to accurately process the glass bulb to ensure smooth edges, no burrs, and meet strict dimensional tolerance requirements. At the same time, advanced punching technology is used to accurately punch holes on the glass bulb to meet the installation requirements of electronic components. The entire processing process is carried out in a dust-free environment to avoid contamination and damage to the glass bulb surface.

[0050] In step S3, the glass bulb is evacuated and baked using a vacuum pump and an exhaust system to remove internal gas and moisture impurities, and a high vacuum state is created and maintained inside the glass bulb. High-purity welding materials and techniques are used during the packaging process to ensure that the connection between the electronic components and the glass bulb is firm and reliable without introducing new impurities.

[0051] The glass shell is deeply evacuated using an efficient vacuum pump and precision exhaust system to ensure that the internal vacuum degree meets the design requirements. During the packaging process, high-purity welding materials and technologies are used, and automated welding equipment is used to ensure that the connection between the electronic components and the glass shell is firm and reliable, while avoiding the introduction of new impurities.

[0052] We use a high-efficiency vacuum pump and a precision exhaust system to deeply exhaust the glass bulb. During this process, we strictly control the exhaust speed and exhaust time to ensure that the internal gas and moisture impurities are completely removed to achieve the vacuum required by the design. Subsequently, the remaining trace moisture and volatile gases are further removed through baking treatment to ensure the purity and stability of the interior of the glass bulb.

[0053] During the packaging process, high-purity welding materials and technology are used to firmly connect the electronic components to the glass shell through automated welding equipment. This welding method not only ensures the reliability of the connection, but also avoids the introduction of new impurities and pollutants. At the same time, advanced sealing technology is used to ensure that the inside of the glass shell is completely isolated from the outside world, maintaining its high vacuum state and reducing interference and noise between electronic components.

[0054] In step S4, the stress distribution inside the glass bulb is made more uniform through the process steps of slowly heating up, keeping warm and cooling down, and the tiny defects and stains on the surface of the glass bulb are removed by one of the physical and chemical methods.

[0055] Through the precise control of slow heating, heat preservation and cooling process steps, the stress distribution inside the glass bulb is more uniform, reducing the thermal stress caused by temperature changes. The tiny defects and stains on the surface of the glass bulb are removed by one or a combination of physical methods (such as polishing) and chemical methods (such as pickling), thereby improving the surface quality of the glass bulb.

[0056] First, through the process steps of slow heating, heat preservation and cooling, the stress distribution inside the glass bulb is made more uniform, reducing the concentration of thermal stress caused by temperature changes. This process not only improves the durability of the glass bulb, but also ensures its stability in extreme working environments.

[0057] Secondly, use one or a combination of physical and chemical methods to remove tiny defects and stains on the glass shell surface. For example, use a polishing machine to finely polish the glass shell surface to remove scratches and tiny pits; at the same time, use chemical methods such as pickling to remove stubborn stains and oxide layers on the surface. These process steps significantly improve the surface quality of the glass shell, making it smoother, flatter and more beautiful.

[0058] In step S5, a comprehensive quality inspection is performed on the glass shell of the electron tube after packaging, including but not limited to appearance inspection, dimension measurement, vacuum test and electrical performance test. The electron tube is subjected to electrical performance test and function verification to ensure that it works stably and reliably and meets the use requirements.

[0059] After the package is completed, the glass shell of the electron tube is fully inspected for quality, including appearance inspection (such as cracks, bubbles, etc.), size measurement (to ensure compliance with design requirements), vacuum test (using a high-precision vacuum gauge to measure the internal vacuum degree) and electrical performance test (such as withstand voltage test, leakage current test, etc.). At the same time, electrical performance test and function verification are carried out to ensure that the electron tube works stably and reliably and meets the use requirements.

[0060] After the package is completed, the glass shell of the electron tube is comprehensively inspected and tested. This step not only covers basic contents such as appearance inspection and dimension measurement, but also includes key indicators such as vacuum degree test and electrical performance test. A high-precision vacuum gauge is used to measure the vacuum degree inside the glass shell to ensure that it meets the design requirements; at the same time, electrical performance test items such as withstand voltage test and leakage current test are carried out to verify the working stability and reliability of the electron tube.

[0061] In addition, the electronic tubes are tested for electrical performance and functional verification. By simulating the signal input and output conditions in the actual working environment, the audio signal transmission quality, sound quality performance, dynamic response characteristics and other indicators of the electronic tubes are tested. The implementation of these test projects ensures that the electronic tubes can meet the various needs of users and perform well in actual applications.

[0062] Embodiment 2:

[0063] See also Figure 1As shown, Gaobei lead-free glass material is selected, and its chemical composition is: silicon dioxide (SiO2): 66.47%, calcium oxide (CaO): 1.90%, barium oxide (BaO): 9.48%, potassium oxide (K2O): 5.27%, sodium oxide (Na2O): 8.00% and partial content of lithium oxide (Li2O), aluminum oxide (Al 2O3), lead monoxide (PbO), zinc oxide (ZnO), iron oxide (Fe2O3), strontium oxide (SrO), manganese oxide (MnO), magnesium oxide (MgO), rubidium oxide (Rb2O), cesium oxide (Cs2O), cadmium oxide (CdO), titanium dioxide (TiO2), zirconium (hafnium) dioxide (Zr(Hf)O2), boron trioxide (B2O3), fluorine (F) and sulfur trioxide (SO3).

[0064] Raw material preparation: Accurately weigh various oxide raw materials according to the above proportions.

[0065] Even mixing: In a dust-free environment, use efficient mixing equipment to fully mix the weighed raw materials to ensure even distribution of the components and avoid uneven distribution of chemical components during the melting process.

[0066] High-temperature melting: The mixed raw materials are sent into a high-temperature furnace and heated to above 1400°C to completely melt the raw materials into uniform glass liquid. During this process, the temperature curve must be strictly controlled to ensure that the molten glass liquid has good fluidity and uniformity.

[0067] Molding: Using a precise molding process (such as blowing), the molten glass is blown into an irregular cylindrical glass shell of the desired shape through a mold or a blowing machine. During this process, the air pressure and temperature must be precisely controlled to ensure that the wall thickness of the glass shell is uniform and the shape is accurate.

[0068] Annealing: Anneal the formed glass bulb to eliminate internal stress by slowly cooling it down, thereby improving the strength and stability of the glass bulb. During the annealing process, the temperature curve and cooling rate must be strictly controlled to avoid cracks or deformation of the glass bulb.

[0069] Cooling and inspection: The annealed glass bulb is naturally cooled to room temperature and subjected to a comprehensive quality inspection. The inspection includes appearance inspection (such as bubbles, cracks, etc.), dimension measurement, hardness test and chemical composition analysis, etc., to ensure that the glass bulb meets the design requirements.

[0070] The application of Gaobei lead-free glass materials not only reduces environmental pollution, but also improves product safety. Since it does not contain harmful substances such as lead, the material is harmless to the human body and the environment during production and use, and meets the green production standards of modern electronic products.

[0073] Raw material preparation: Prepare the required chemical components and ensure that all raw materials meet the relevant quality and purity requirements. Pay special attention to the precise control of lead and other heavy metal elements to avoid exceeding safety standards.

[0074] Batching and mixing: According to the specific formula, each chemical component is accurately weighed and mixed evenly. This process needs to be carried out in a dust-free environment to avoid contamination.

[0075] Melting and molding: The mixed raw materials are placed in a high-temperature furnace for melting. During the melting process, the temperature and time are strictly controlled to ensure that all the ingredients are fully fused. The molten glass is then poured into a mold for molding to form a glass tube of the desired shape.

[0076] Cooling and solidification: Control the cooling speed and time to gradually solidify the glass tube into the desired shape and size. During this process, care must be taken to avoid cracks or deformation.

[0077] Processing and finishing: The solidified glass tube is finely processed, such as cutting and grinding, to achieve the required size and shape. At the same time, the appearance and quality of the glass tube are checked to ensure that there are no defects and cracks.

[0078] Quality inspection and packaging: The finished glass tubes are subjected to comprehensive quality inspection, including chemical composition analysis, physical property testing, etc. Qualified glass tubes are packaged and their special uses and precautions are clearly marked.

[0079] During the production and use process, strict safety control and environmental protection measures must be taken. Waste containing heavy metal elements such as lead must be properly handled to avoid environmental pollution. At the same time, the occupational health protection of employees must be strengthened to ensure safety during the production process.
