[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Reference Figure 1-2A drying apparatus for producing piezoelectric quartz crystal frequency wafers includes a support frame 1 and a drying chamber 2 horizontally mounted on the support frame 1. A horizontally arranged drying cylinder 3 is installed inside the drying chamber 2. A conveyor 5 for moving the piezoelectric quartz crystal frequency wafers is also mounted on the support frame 1, and the conveyor 5 horizontally passes through the drying cylinder 3 and the drying chamber 2. The support frame 1 is the basic support structure of the entire drying apparatus and is typically made of a robust and durable metal material, such as stainless steel or aluminum alloy, ensuring the stable installation of the drying chamber 2 and the conveyor 5. The drying chamber 2 is the main body of the apparatus, used to house the drying cylinder 3 and a heater 6, and providing a relatively enclosed environment to reduce heat loss and external contamination. Preferably, the drying chamber 2 is rectangular in shape for easy operation and maintenance. The inner wall of the drying chamber 2 is typically made of corrosion-resistant and high-temperature-resistant materials to ensure stability and safety during long-term use. The drying cylinder 3 is the core component of the apparatus, used as the structure for directly drying the piezoelectric quartz crystal frequency wafers. Preferably, the drying cylinder 3 is cylindrical in shape.

[0023] The conveyor 5 is used to transport the piezoelectric quartz crystal frequency sheet from the inlet 11 of the drying chamber 2 to the outlet, realizing the input and output operation of the piezoelectric quartz crystal frequency sheet and reducing manual operation. Preferably, the conveyor 5 includes a transmission roller installed on the frame on both sides of the drying chamber 2 and a conveyor belt fitted on the transmission roller. Several ventilation holes are provided on the conveyor belt. A drive motor for driving the transmission roller to drive the conveyor belt to rotate is installed on the frame. In actual use, it is only necessary to use the drive motor to drive the drying cylinder 3 to swing back and forth 90°, that is, first swing 90° clockwise and then swing 90° counterclockwise.

[0024] The drying cylinder 3 is rotatably installed inside the drying chamber 2. A power device 4 for driving the drying cylinder 3 to reciprocate is also installed inside the drying chamber 2. A heater 6 for heating and drying the piezoelectric quartz crystal frequency sheet is installed inside the drying cylinder 3. Preferably, three sets of heaters 6 are provided, respectively located in the middle and on both sides of the drying cylinder 3. Each set of heaters 6 includes at least two heaters 6, evenly distributed along the circumference of the drying cylinder 3. This arrangement ensures that the frequency sheet is heated evenly during the drying process, avoiding localized overheating or uneven drying. More preferably, the heaters 6 are electric heaters, which have the advantages of fast heating speed and controllable temperature.

[0025] The power device 4 is used to drive the drying cylinder 3 to swing, so that the heater 6 can move relative to it, thereby enabling more comprehensive and uniform heating and drying of the piezoelectric quartz crystal frequency sheet and avoiding the formation of drying dead zones; preferably, the power device 4 is a geared motor, and the motor shaft of the geared motor is connected to the drying cylinder 3 through a transmission wheel.

[0026] An inlet 11 cooperating with a conveyor 5 is provided on one side of the drying chamber 2, and an outlet cooperating with a conveyor 5 is provided on the other side of the drying chamber 2. A blower 8 is installed on the drying chamber 2 at the inlet 11, and an exhaust fan 10 is installed on the drying chamber 2 at the outlet. The air outlet of the blower 8 and the air inlet of the exhaust fan 10 are both oriented towards the drying cylinder 3. The blower 8 is used to blow fresh air into the drying cylinder 3 to accelerate moisture evaporation; the blower is used to promptly discharge the moisture generated after drying. Preferably, there are two blowers 8 and two exhaust fans 10, which are respectively located on the upper and lower sides of the drying cylinder 3. An air filter 9 is also installed at the air inlet of the blower 8 to remove dust and impurities from the air and protect the internal components from contamination.

[0027] To ensure that the airflow generated by the blower 8 is evenly distributed within the drying cylinder 3, several guide plates 7 are installed on the inner wall of the drying cylinder 3. The guide plates 7 oscillate back and forth with the drying cylinder 3, disturbing the airflow and ensuring that all parts of the piezoelectric quartz crystal frequency wafer are thoroughly dried, thereby improving the quality and production efficiency of the piezoelectric quartz crystal frequency wafer product.

[0028] The actual working process of this device is as follows:

[0029] Start the drive motor to make the transmission roller drive the conveyor belt to start rotating, ensuring that the conveyor belt runs smoothly without jamming or deviation. At the same time, the power equipment 4 (gear motor) drives the drying cylinder 3 to rotate through the transmission wheel.

[0030] The piezoelectric quartz crystal frequency sheet to be dried is neatly placed at the beginning of the conveyor belt, or the piezoelectric quartz crystal frequency sheet is first placed on the quartz crystal holder 1, and then the quartz crystal holder 1 is placed on the conveyor belt.

[0031] As the conveyor belt moves, the piezoelectric quartz crystal frequency sheet is fed into the inlet 11 of the drying chamber 2 and enters the drying cylinder 3 along the conveyor belt.

[0032] After the piezoelectric quartz crystal frequency plate enters the drying cylinder 3, the three sets of heaters 6 start working to heat the drying cylinder 3 evenly; the temperature and time of the heaters 6 can be adjusted according to actual needs;

[0033] Secondly, the blower 8 is started, blowing fresh air into the drying cylinder 3 to accelerate the evaporation of moisture on the surface of the piezoelectric quartz crystal frequency plate. The exhaust fan 10 works at the outlet to promptly remove the moisture generated after drying.

[0034] The guide plate 7 guides the airflow and heat to be evenly distributed on the inner wall of the drying cylinder 3, ensuring that all parts of the piezoelectric quartz crystal frequency plate are fully dried;

[0035] After a period of drying, the piezoelectric quartz crystal frequency sheet is carried out of the drying chamber 2 by the conveyor belt, completing the drying process;

[0036] The dried piezoelectric quartz crystal frequency wafers are inspected to ensure they meet quality requirements before being packaged and stored for later use.

[0037] In summary, this drying device for the production of piezoelectric quartz crystal frequency wafers achieves efficient and uniform drying through reasonable structural design and workflow, ensuring the quality and production efficiency of piezoelectric quartz crystal frequency wafer products.
