[0026] 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.

[0027] See also Figure 1-4 The present invention provides a technical solution: a method for preparing a micro-machined alkali metal atomic gas chamber in a metal periodic structure bonding process, comprising the following steps:

[0028] S1: Select glass of specified installation size according to the corresponding size, ensure that the glass material is uniform and flawless, and perform necessary cleaning and pretreatment to remove surface contaminants;

[0029] S2: Add electrodes to the two connected pieces of glass and place them on a heating table for heating. The glass will bond under heating. Add electrodes to the two connected pieces of glass and place them on a special heating table 6 for heating. During the heating process, the key to the metal periodic structure bonding process is to use heating to promote the migration and rearrangement of metal ions inside the glass, creating favorable conditions for the subsequent bonding process.

[0030] S3: At this time, image charges will be generated on the surface of the glass. As time goes by, an electrostatic field will gradually form on the surface of the glass until the internal and external potentials reach equilibrium. As the heating progresses, image charges will be generated on the surface of the glass and an electrostatic field will gradually form. This process utilizes the characteristics of charge distribution in the metal periodic structure to promote close bonding between the glasses through the action of the electric field. When the internal and external potentials reach equilibrium, the effect of the electrostatic field is maximized;

[0031] S4: The electrostatic force on the glass will cause a slight deformation between the glass and the glass, so that the adjacent glass can be tightly fitted together to form a sealed section. Under the action of the electrostatic force, the glass and the glass will have a slight deformation, which helps to fit the adjacent glass tightly together to form a preliminary sealed section.

[0032] S5: At this time, under high temperature, a strong chemical bond will be formed between the two glasses, making the two glasses closely connected together, thus achieving a sealed docking effect. Under high temperature, a strong chemical bond will be formed between the two glasses, which is the core of the metal periodic structure bonding process. The formation of the chemical bond makes the two glasses closely connected together, achieving a highly sealed docking effect;

[0033] S6: When multiple groups of glass are bonded together, they form a closed space, which can be used for physical experiments. When multiple groups of glass are bonded together through the above steps, they together form a closed space, namely the alkali metal atom gas chamber. This gas chamber can be used for physical experiments and provide scientists with a stable and reliable experimental environment.

[0034] The bonding processing accessories include: a side glass plate 1, an upper glass plate 2, a docking joint 3, an outlet 4 and an upper cover 5. The top of the side glass plate 1 is covered with the upper glass plate 2, and two groups of docking joints 3 are arranged on the surface of the upper glass plate 2. An outlet 4 is arranged on the upper surface of the upper glass plate 2 and located at the center of the docking joint 3, and the upper cover 5 is placed on the top of the outlet 4.

[0035] An annular groove is provided at the bottom edge of the upper cover 5, and the annular groove is connected and engaged with the docking joint 3. A plurality of annular grooves are provided at the edge of the upper cover 5, and then the annular groove and the docking joint 3 are connected, and the docking joint 3 and the groove are run-in, so that the groove and the docking joint 3 are kept in contact with each other, thereby achieving a sealed connection between the upper cover 5 and the docking joint 3. In terms of the bonding processing accessories, we use components such as the side glass plate 1, the upper glass plate 2, the docking joint 3, the outlet 4 and the upper cover 5. These components ensure the sealing and stability of the air chamber through precise design and processing. In particular, the design of the relative connection and engagement between the annular groove at the bottom of the upper cover 5 and the docking joint 3, as well as the close fit after the running-in treatment, further improve the sealing performance of the air chamber.

[0036] The bonding tooling includes a heating table 6, a processing tooling 7, a plug 8, a pressing plate 9, a mounting plate 10, a side plate 11, a mounting piece 12 and a heating wire 13. The heating table 6 is installed on the processing tooling 7. A plug 8 is fixedly arranged on the inner side of the processing tooling 7. The processing tooling 7 is provided with four sides, and the bottom surface of the processing tooling 7 is connected to the heating table 6. In terms of the bonding tooling, we have designed a tooling system including a heating table 6, a processing tooling 7, a plug 8, a pressing plate 9, a mounting plate 10, a side plate 11, a mounting piece 12 and a heating wire 13. This tooling system not only ensures that the glass is heated evenly during the heating process, but also realizes the simultaneous extrusion of three sides of the glass through the cooperation of the inclined side plate 11 and the hydraulic rod, thereby enhancing the bonding effect.

[0037] A pressing plate 9 is also placed inside the processing tool 7, and a mounting plate 10 is fixedly connected to the inner wall of the pressing plate 9. One end of the mounting plate 10 is connected to a side plate 11, and both the mounting plate 10 and the side plate 11 are provided with mounting holes connected to the hydraulic rod.

[0038] The side panel 11 is an inclined structure, and the inclination angle of the side panel 11 is 45°. It is installed by the side panel 11 inclined at 45° and the hydraulic rod also inclined at 45°. When the hydraulic rod moves, the side panel 11 moves at 45°, so that the pressure plate 9 can squeeze three sides of the glass at the same time.

[0039] The pressure plate 9 is composed of three plates, and a mounting member 12 is connected between two adjacent pressure plates 9. The mounting member 12 is fixed to the pressure plate 9 by bolts, and the three pressure plates 9 are spliced ​​together. Then, the bolts are passed through the mounting member 12 and connected to the pressure plate 9, so that the three pressure plates 9 are spliced ​​and installed together.

[0040] A heating wire 13 is arranged inside the processing tool 7, and the heating wire 13 is evenly distributed inside the four surfaces of the processing tool 7, and the power end of the heating wire 13 is arranged at the lower end of the processing tool 7. By using the heating wire 13 evenly arranged inside the processing tool 7, the processing tool 7 can evenly heat the glass placed above.

[0041] In summary: Figure 1-4 As shown, when using the method for developing a micro-machined alkali metal atomic gas chamber based on the metal periodic structure bonding process, we first accurately select the side glass plate 1 according to the required size and install electrodes on it. Subsequently, the two side glass plates 1 are docked according to the predetermined assembly shape and placed on a special processing tool 7. The processing tool 7 is equipped with uniformly distributed heating wires 13, which provide a uniform heating environment for the glass during the processing process, which is a key step in realizing the metal periodic structure bonding process.

[0042] While heating, we use the inclined hydraulic device to apply pressure to the glass plate through the side plate 11. The 45° inclined design of the side plate 11 enables the hydraulic rod to more effectively squeeze the glass plate on three sides to ensure close contact between the glass plates. With the continuous action of heating and pressure, the glass surface begins to form image charges and gradually builds an electrostatic field until the internal and external potentials reach equilibrium. In this process, the electrostatic force causes slight deformation of the glass and the glass, which further promotes the close fit between the glass plates.

[0043] After the two side glass plates 1 are bonded under heat and pressure, we then butt the other side glass plate 1 against the first two bonded glass plates, and continue the bonding process according to the suitable position for pressing on the processing tool 7. During the bonding process, we specially reserve a channel, which is sleeved on the plug 8, to facilitate the subsequent air chamber inflation and deflation operations.

[0044] As the bonding of the glass plates is completed, they form a closed space, namely, an alkali metal atom gas chamber, which is inflated and deflated through a specially designed outlet 4, while the upper cover 5 is tightly engaged with the butt joint 3 through the annular groove at the bottom thereof, thereby achieving a reliable seal of the outlet 4.

[0045] The entire development method not only fully utilizes the advantages of metal periodic structure bonding technology, such as the formation of strong chemical bonds at high temperatures and the auxiliary effect of electrostatic fields, but also ensures the sealing and stability of the gas chamber through careful tooling design and operation procedures. This micro-machined alkali metal atomic gas chamber has a wide range of application prospects in physical experiments and provides an important experimental platform for scientific research.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
