[0001] The invention relates to the technical field of quartz crystal resonator production equipment, and in particular to a quartz crystal resonator aging system. Background Art
[0002] A quartz crystal resonator, also known as quartz crystal or crystal oscillator, is an electronic component made using the piezoelectric effect of quartz crystal. In its manufacturing process, aging treatment is a critical process to improve product quality and reliability. Through this process, potential early defects can be effectively identified and eliminated, thereby ensuring that the crystal oscillator has excellent stability and long-lasting performance in practical applications.
[0003] For example, the Chinese patent with application number 202420121039.8 discloses a quartz crystal resonator aging system, including a loading and unloading mechanism, a control unit and an aging oven; the aging oven includes a box and multiple furnaces, the furnace is used to store the quartz crystal resonator and then bake the quartz crystal resonator, the multiple furnaces are independent of each other, and a proximity sensor and a heater are arranged in the furnace, the proximity sensor is used to detect the proximity information of the quartz crystal resonator, the control unit is used to generate a driving instruction after receiving the proximity information, and the heater is used to heat the furnace after receiving the driving instruction; the loading and unloading mechanism includes a moving component and a loading and unloading component, and the moving component and the loading and unloading component are slidably connected. By baking the quartz crystal resonator through multiple independent furnaces, the energy consumption can be proportional to the number of quartz crystal resonators, the energy utilization rate can be improved, and the production cost can be reduced.
[0004] However, during the aging process, on the one hand, the high-temperature aging box of the prior art mostly adopts the form of single-side air outlet and single-side air return, which makes the temperature of the quartz crystal resonator near the air outlet higher, resulting in uneven heating; on the other hand, the vibration of the high-temperature aging box itself and the hot air blowing onto the sample tray are easy to cause the vibration of the quartz crystal resonator, thereby affecting the aging effect of the quartz crystal resonator; to reduce the impact, the prior art usually has a spring-type shock-absorbing structure on the placement piece, mostly located at the four corners of the sample tray. However, under long-term use in a high-temperature environment, the spring may decay or fail, causing the sample tray to tilt, thereby affecting the aging effect of the crystal oscillator and may cause some crystal oscillators to bear additional mechanical stress.

[0047] 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 those skilled in the art without creative work are within the scope of protection of the present invention. Example
[0048] In the actual production process, since most high-temperature aging boxes adopt the form of single-side air outlet and single-side air return, such as left-side air outlet and right-side air return, the temperature of the quartz crystal resonator near the air outlet is higher; the prior art balances the temperature by rotating the sample tray, but the vibration generated during the rotation will cause the mechanical stress inside the quartz crystal resonator to be incompletely released, and may even cause the crystal oscillator to be subjected to additional mechanical stress. This embodiment is specially invented to solve the above problem.
[0049] See also Figures 1 to 4 As shown, a quartz crystal resonator aging system according to an embodiment of the present invention comprises an aging box 1 and a control box 2 arranged on one side of the aging box 1, a control panel is arranged on one side of the control box 2, a control unit is arranged in the control box 2, the control unit and the control unit are electrically connected, a user can adjust the temperature, humidity and other parameters in the aging box 1 through the control panel, an aging chamber 11 is arranged in the aging box 1, a blowing unit and a heating unit are arranged in the aging box 1, the blowing unit and the heating unit are located at the bottom of the aging box 1, and are used to input hot air into the aging chamber 11, the blowing unit comprises a blower, an air filter, a temperature sensor and a controller, the heating unit comprises an electric heater located on the air outlet side of the blower, a heating tube bracket, insulation cotton and a heat sink, an air inlet channel 12 and a return air channel 13 are respectively arranged on the left and right sides of the aging chamber 11, a sealing door is hinged on the front side of the aging box 1, and also comprises an air collecting component 3, a partition component 4 and a placement component 6.
[0050] It should be added that the return air duct 13 has two return air directions, one is for the return air of the blower unit, that is, the return air side of the blower unit, and the other is located at the top of the aging box 1 to discharge part of the hot air for ventilation.
[0051] The air collecting component 3 is located in the air inlet channel 12. When the hot air is sent to the air inlet channel 12, the air collecting component 3 collects the hot air and distributes the air volume.
[0052] See also Figure 4 and Figure 6 As shown, the air collecting component 3 includes an air collecting hood 31 located at the bottom of the air inlet channel 12, the air collecting hood 31 is a trumpet-shaped structure, the top of the air collecting hood 31 is fixedly connected to an air collecting duct 32, and a plurality of air outlet ducts 33 evenly distributed up and down are arranged on the side wall of the air collecting duct 32, an air inlet side plate 14 is arranged between the air inlet channel 12 and the aging chamber 11, and a plurality of air inlet slots 141 evenly distributed up and down are opened on the air inlet side plate 14, and a diverter hood 34 is fixedly connected to one side of the air inlet slot 141 located in the air inlet channel 12, and the diverter hood 34 is a trumpet-shaped structure, and a connecting pipe is fixedly connected to the end of the diverter hood 34 away from the air inlet slot 141, and a flow regulating valve 35 is arranged between the connecting pipe and the air outlet duct 33.
[0053] See also Figures 5 to 7As shown, the partition component 4 is located in the aging chamber 11 and cooperates with the air collecting component 3, and the partition component 4 cooperates with the aging chamber 11 to form a plurality of independent chambers 5, and the independent chambers 5 are arranged in a matrix. A temperature sensor is installed on the side wall of each independent chamber 5, and the control unit inside the control box 2 can receive real-time feedback data from the temperature sensor and present the data on the control panel. When the temperature does not reach the predetermined value, the control unit sends a correction instruction to the blowing unit and the heating unit, and the air output of the blowing unit is compensated. The hot air distributed by the air collecting component 3 is guided by the partition component 4 and then transported to each independent chamber 5.
[0054] See also Figure 6 and Figure 7 As shown, the partition assembly 4 includes a partition frame 41, and the partition frame 41 cooperates with the aging chamber 11 to form an independent chamber 5. The partition frame 41 includes a plurality of horizontal plates 411 evenly distributed up and down, and the four corners of two adjacent horizontal plates 411 are fixedly connected with support columns 412, and at least one partition plate 413 is fixed between the two adjacent horizontal plates 411. The other horizontal plates 411 except the bottom one are provided with an air inlet cavity 4111 connected with the air inlet groove 141, and the bottom of the air inlet cavity 4111 is provided with a plurality of horizontal plates 4111. A plurality of air outlet holes 4112 communicating with the independent chamber 5 are provided in the part, a return air side plate 15 is arranged between the return air duct 13 and the aging chamber 11, a plurality of return air slots 151 arranged up and down are provided on the return air side plate 15, a return air chamber 4113 located above the air inlet chamber 4111 is provided in the other horizontal plates 411 except the top one, a return air hole 4114 communicating with the independent chamber 5 is provided on the top of the return air cavity 4113, and the return air cavity 4113 is communicated with the return air slots 151.
[0055] In order to avoid the problem of inconsistent air volume between the two adjacent independent chambers 5 on the left and right, the diameters of the air outlet holes 4112 in the two adjacent independent chambers 5 on the left and right change in a step-by-step manner. In this embodiment, the diameter of the air outlet hole 4112 in the left independent chamber 5 is smaller than the diameter of the air outlet hole 4112 in the right independent chamber 5.
[0056] See also Figure 5 and Fig.12 As shown, the placement piece 6 is located in the independent chamber 5 and the number is consistent with the independent chamber 5. A sample tray 7 is installed on the placement piece 6. The sample tray 7 is provided with a plurality of matrix-arranged slots for placing the quartz crystal resonator. In addition, the sample tray 7 is also provided with a guide groove for guiding the airflow.
[0057] When in use, first turn on the blower unit and the heating unit through the control panel on the control box 2 to preheat the aging box 1 in advance. During the preheating stage, the blower unit is at the maximum wind speed. At the same time, the worker preheats the sample tray 7 loaded with the quartz crystal resonator to make the quartz crystal resonator reach a stable temperature state to avoid large temperature fluctuations when placed in the aging chamber 11.
[0058] Then, the sealed door of the aging box 1 is opened and the preheated quartz crystal resonator is mounted on the placement piece 6, and the sealed door is closed and the aging box 1 is controlled by the control panel to formally start heating.
[0059] During the heating process, the hot air passes through the air collecting hood 31 and enters the air collecting duct 32. The multiple flow regulating valves 35 on one side of the air collecting duct 32 respectively adjust the air intake of each section, so that the air volume entering each air inlet chamber 4111 is in a relatively balanced state. Since the independent chamber 5 is connected with the return air chamber 4113 and the return air channel 13, the independent chamber 5 is in a relatively negative pressure state. The gas entering the air inlet chamber 4111 enters the independent chamber 5 under the guidance of the negative pressure, and finally enters the return air channel 13 through the return air chamber 4113, thereby forming a complete gas circulation.
[0060] Furthermore, when the temperature inside each independent chamber 5 reaches a predetermined value and is in a relatively balanced state, the blowing unit and the heating unit stop working until the temperature sensor detects that the temperature difference in each independent chamber 5 is greater than 0.5°C, and then the blowing unit and the heating unit start working again.
[0061] By means of the air collecting component 3, the partition component 4 and the placement component 6, the aging chamber 11 is divided into a plurality of independent chambers 5, and the side air outlet form is adjusted. On the basis of not moving the sample tray 7, the temperature of the quartz crystal resonator on each sample tray 7 is made more uniform, thereby avoiding the problem of higher temperature of the quartz crystal resonator near the air outlet. Example
[0062] In actual use, it was found that only adjusting the diameter of the air outlet 4112 is not enough to solve the problem of air volume difference and temperature difference between the left and right chambers. This is because the physical properties and flow characteristics of gas are very different from those of liquid. When gas flows in the chamber, it is more likely to form turbulence. Therefore, it was found in actual observation that the two adjacent independent chambers 5 on the left and right will have inconsistent air volume. Therefore, further improvements are made on the basis of the above embodiment.
[0063] See also Figure 8 As shown, it also includes an adjustment component 8, which is located in the air inlet cavity 4111 and is used to adjust the air output of the air outlet 4112 corresponding to the single independent chamber 5.
[0064] See also Figure 8 and Fig. 9 As shown, the adjustment component 8 includes an adjustment plate 81, on which a plurality of adjustment holes 811 matching the air outlet holes 4112 are provided, a connecting rod 82 is fixedly connected to one side of the adjustment plate 81, an end of the connecting rod 82 away from the adjustment plate 81 is threadedly connected to a sleeve 83, an end of the sleeve 83 away from the connecting rod 82 is fixedly connected to an adjustment motor 84, and the adjustment motor 84 is located in the control box 2 and is connected to the control unit through an electrical signal.
[0065] It should be noted that each air inlet chamber 4111 is provided with an adjustment plate 81, a connecting rod 82 and a sleeve 83, but there is only one adjustment motor 84. Two adjacent sleeves 83 are connected by a synchronous belt transmission structure to achieve the effect of one adjustment motor 84 synchronously controlling multiple adjustment plates 81.
[0066] On the basis of the above embodiment, during use, when the temperature sensor detects a relatively obvious temperature difference between the two adjacent independent chambers 5 on the left and right, the control unit sends an electrical signal to the adjustment motor 84, the adjustment motor 84 starts and drives the adjustment plate 81 to move left and right under the transmission of the connecting rod 82 and the sleeve 83, thereby ensuring that the air volume in each independent chamber 5 is consistent.
[0067] Through the settings of the adjustment plate 81, the connecting rod 82, the sleeve 83 and the adjustment motor 84, whenever the temperature sensor detects an obvious temperature difference between two independent chambers 5 adjacent to each other on the left and right, the adjustment motor 84 will drive the adjustment plate 81 to move left and right. At this time, the air outlet 4112 and the adjustment hole 811 are staggered, and the air volume is adjusted. Through this active adjustment method, the temperature uniformity in each independent chamber 5 is further improved. Example
[0068] It is found in actual use that after the sample tray 7 is installed on the placement piece 6, the vibration during the operation of the aging box 1 (caused by the motor, blower, hot air, etc.) may affect the quartz crystal resonator; in order to reduce the impact, the prior art usually provides a spring-type shock-absorbing structure on the placement piece 6, which is mostly located at the four corners of the sample tray 7.
[0069] However, in a high temperature environment, the spring may decay or fail after long-term use, causing the sample tray 7 to tilt, thereby affecting the crystal oscillator aging effect and possibly causing part of the crystal oscillator to bear additional mechanical stress. In view of the above problems, further improvements are made on the basis of the above embodiments.
[0070] See also Fig.10 As shown, a shock absorbing component 9 is also included. The shock absorbing component 9 is located between the placement piece 6 and the sample tray 7 to reduce the shock of the sample tray 7.
[0071] See also Fig.10 and Fig.12 As shown, the placement member 6 includes a placement plate 61 fixedly connected to the horizontal plate 411 . The placement plate 61 is a ring-shaped structure. The four corners of the placement plate 61 are fixedly connected with clamping members 62 for clamping and fixing the sample tray 7 .
[0072] See also Fig.11 and Fig.12 As shown, the clamping member 62 includes a support rod fixedly connected to the placement plate 61 , and a pressing plate that moves up and down is slidably connected to the support rod through a spring, and the pressing plate is in contact with the sample tray 7 .
[0073] See also Fig.11 and Fig.12 As shown, the shock-absorbing assembly 9 includes an air storage portion 91, a placement groove 63 is provided on the placement plate 61, the air storage portion 91 is located in the placement groove 63 and its height after being filled with air is higher than the placement groove 63, an air intake pipe is provided on one side of the air storage portion 91, a conical tube 92 connected to the air intake cavity is fixedly connected to the bottom of the horizontal plate 411 located above the air storage portion 91, an end of the conical tube 92 away from the horizontal plate 411 is connected to the air intake pipe through a hose, a gas one-way valve 93 is provided on the hose, and an air guide member 94 matching the conical tube 92 is fixedly connected to the middle of the air intake cavity, the air guide member 94 includes an air guide plate, and the height of the air guide plate is consistent with the height of the air intake cavity 4111.
[0074] See also Fig.11 As shown, a connecting pipe 95 is fixedly connected between the air guide members 94 in the same air inlet cavity.
[0075] During use, in the preheating stage of the aging box 1, the gas entering the air inlet chamber 4111 enters the conical tube 92 under the guidance of the air guide plate, and then enters the air storage section 91 after passing through the hose and the gas one-way valve 93. The air storage section 91 is inflated and gradually expands until the air pressure in the air storage section 91 is consistent with the air inlet pressure of the air guide plate, and the gas one-way valve 93 is in a closed state.
[0076] Through the arrangement of the guide, the gas storage part 91, the gas one-way valve 93 and the conical tube 92, during the preheating stage of the aging box 1, the gas storage part 91 will be pre-inflated to a set pressure value to ensure the uniformity and stability of the temperature in the box; after the preheating is completed, the staff will accurately install the sample tray 7 with the quartz crystal resonator between the clamping part 62 and the gas storage part 91. The gas storage part 91 provides effective buffering and shock absorption for the sample tray 7 through the internal gas pressure, thereby reducing the influence of external vibration on the mechanical stress of the crystal oscillator.
[0077] Another significant advantage of the gas storage unit 91 is its self-recovery ability. Even if a slight gas leakage occurs during the aging process, each time the aging box 1 re-enters the preheating stage, the gas storage unit 91 will automatically replenish the gas and return to the optimal working state.
[0078] This design avoids the elastic fatigue or permanent deformation problems caused by long-term high-temperature use of traditional spring shock absorption systems, thereby ensuring the consistency and reliability of the shock absorption effect; therefore, the aging box 1 using the air storage part 91 for shock absorption can more effectively maintain the aging conditions of the quartz crystal resonator and improve the quality and consistency of the product.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
