[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Refer to Figure 1-2 , a portable airtightness detection device for quartz crystal resonators, comprising a detection bracket 1. A vertically arranged circular bracket 2 is installed on the detection bracket 1. The circular bracket 2 is rotationally installed on the detection bracket 1 through a support shaft. A driving device 3 for driving the support shaft to drive the circular bracket 2 to rotate is further installed on the detection bracket 1. Preferably, the driving device 3 is a stepping motor. One end of the support shaft is fixedly connected to the circular bracket 2, and the other end of the support shaft is installed on the detection bracket 1 through a bearing and a bearing seat. The motor shaft of the stepping motor is in transmission connection with the support shaft; the detection bracket 1 is the main frame of the entire equipment, providing stable support. The circular bracket 2 is installed on the detection bracket 1 through a precise support shaft and can rotate smoothly around the center of the support shaft. One end of the support shaft is firmly connected to the circular bracket 2, and the other end is cleverly installed on the detection bracket 1 through high-quality bearings and a sturdy bearing seat, ensuring smooth and stable rotation. The stepping motor serves as the driving device 3, and its motor shaft is connected to the support shaft through a transmission device (such as gear or belt drive). By precisely controlling the operation of the stepping motor, precise rotation of the circular bracket 2 is achieved;

[0021] Specifically, several detection plates 4 are vertically installed on the circumferential side of the circular bracket 2. The upper part of the detection plate 4 is rotatably installed on the circular bracket 2 through a rotating shaft. A support plate 5 is horizontally installed at the bottom of the detection plate 4. On the support plate 5, there are provided at least two insertion holes 10 for cooperating with quartz crystal resonators, facilitating the insertion of the quartz crystal resonators to be detected into the support plate 5 through the insertion holes 10, so as to move together with the detection plate 4. There are multiple insertion holes 10, facilitating the adaptation to quartz crystal resonator products of different models and sizes, enhancing the flexibility and compatibility of detection; the detection plate 4 is installed on the circular bracket 2 through a rotating shaft, enabling the detection plate 4 to rotate relative to the circular bracket 2, thereby ensuring that the detection plate 4 is always in a vertical state, so as to prevent the quartz crystal resonator from falling; preferably, the detection plate 4 is in a frustum shape with a smaller upper part and a larger lower part;

[0022] Preferably, there are 4 - 8 detection plates 4, and the 4 - 8 detection plates 4 are evenly distributed along the circumferential side of the circular bracket 2. There are 2 - 4 insertion holes 10 on each support plate 5.

[0023] A detection water tank 6 for detecting the airtightness of the quartz crystal resonator is provided directly below the circular bracket 2. Preferably, the detection water tank 6 is integrally in a cuboid shape and is made of transparent glass or transparent PVC material. Such a design makes the detection process clear at a glance and convenient for observation. At the same time, the detection water tank 6 is externally connected to a water supply pipe 8, and a water level gauge 9 is also installed on the detection water tank 6 to monitor the water level change in real time and adjust the water volume as needed to maintain an appropriate water level.

[0024] In order to effectively remove the moisture on the surfaces of the detection plate 4 and the quartz crystal resonator and prepare for subsequent work, a blowing device 7 is also installed on the detection bracket 1 on one side of the circular bracket 2. Preferably, the blowing device 7 is a hot air blower, which can provide warm air flow, and its air volume and temperature can also be adjusted according to practical needs.

[0025] The specific working process of the portable quartz crystal resonator airtightness detection device provided by this application is as follows:

[0026] 1. Inject an appropriate amount of water into the detection water tank 6 to ensure that the water level reaches the detection requirements;

[0027] 2. Place the quartz crystal resonators to be detected in the insertion holes 10 on the support plate 5 of the detection plate 4 in a certain order to ensure that each resonator is stably placed;

[0028] Start the stepper motor to drive the circular bracket 2 to rotate slowly. As the circular bracket 2 rotates, each detection plate 4 and the quartz crystal resonator on it will sequentially enter the detection water tank 6. The airtightness of the resonator is inspected by soaking it in water. If there is a problem with the airtightness of the resonator, water will quickly seep in, forming obvious bubbles or water leakage;

[0029] 3. Through the transparent detection water tank 6, the operator can clearly observe the detection situation of each resonator and record the detection results in a timely manner;

[0030] 4. Start the hot air blower to blow-dry the detection plate 4 and the quartz crystal resonator after the water drains out to remove the residual moisture;

[0031] At the same time, the operator takes out the detected quartz crystal resonator on one side of the circular bracket 2 and replaces it with the quartz crystal resonator to be detected;

[0032] Then, the stepper motor operates to make the undetected resonator continue to enter the detection water tank 6 for detection;

[0033] Repeat this cycle, and the airtightness detection operation of the quartz crystal resonator can be realized in a more simplified and rapid manner, significantly improving the detection efficiency, ensuring the product quality of the quartz crystal resonator, and meeting the actual requirements of the production line.
