Description

Technical Field

[0001] The present invention relates to the technical field of quartz crystal resonator testing, and more particularly to a low-power startup testing device for quartz crystal resonators. Background Art

[0002] A quartz crystal resonator, also simply referred to as a quartz crystal or crystal oscillator, is an electronic component that utilizes the piezoelectric effect of a quartz crystal (also known as rock crystal) to generate a highly accurate oscillation frequency;

[0003] The chemical composition of a quartz crystal is silicon dioxide, and its working principle is based on the piezoelectric effect. When an alternating voltage is applied to the quartz wafer, the wafer will generate periodic mechanical vibrations with the frequency of the alternating voltage; at the same time, the mechanical vibrations generate charges on the wafer to form an alternating current. Generally speaking, the amplitude of this mechanical vibration is very small, and the vibration frequency is very stable. However, when the frequency of the external signal source is equal to the natural frequency of the crystal, the crystal undergoes resonance, and at this time, the alternating current in the external circuit of the crystal is also the largest. This phenomenon is called the piezoelectric resonance of the quartz crystal. The frequency stability of the crystal oscillator circuit is very good, so it is widely used in electronic systems to provide a reference clock for them;

[0004] After the quartz crystal resonator is produced, it needs to be tested for its qualification. During the testing process of existing testing equipment, by setting the quartz crystal resonator in a low-power circuit, and then testing the resistance value of the quartz crystal resonator to determine whether the quartz crystal resonator is qualified, or by using a multimeter (R×10k range) to measure the resistance value across the quartz crystal resonator. If the resistance value is infinite, it indicates that there is no short circuit or leakage in the quartz crystal resonator. However, the existing testing methods need to test each quartz crystal resonator one by one, so it is not convenient to ensure the testing efficiency of the quartz crystal resonator.

[0016] 1. During the process of testing the quartz crystal resonator of the present invention, the quartz crystal resonator to be tested is installed in the first sorting assembly and the second sorting assembly at a position where the sorting module is far from the test component. Then, the first servo motor works to drive the transmission gear to rotate. Subsequently, under the meshing action of the transmission gear and the transmission gear ring, the transmission gear ring rotates, and then drives the transmission circular plate to rotate. Through the connection and positioning of the connecting shaft, the test body rotates synchronously with the transmission circular plate.

[0041] Working principle of the present invention: During the testing process of the quartz crystal resonator, the quartz crystal resonator to be tested is installed in the first sorting component 302 and the second sorting component 303 at a position of the sorting module 3 away from the testing component 2. Then, the first servo motor 102 operates to drive the transmission gear 103 to rotate. Subsequently, under the meshing action of the transmission gear 103 and the transmission gear ring 204, the transmission gear ring 204 rotates, and then drives the transmission circular plate 203 to rotate. Through the connection and positioning of the connecting shaft 202, the testing main body 201 rotates synchronously with the transmission circular plate 203. Subsequently, under the connection of the L-shaped connecting pipe 105, the testing main body 201 rotates synchronously with the rotating ring plate 104. Then, during the rotation of the testing main body 201, the sorting module 3 is positioned through the first positioning groove 205 and the second positioning groove 206, thereby driving the sorting module 3 to rotate synchronously with the testing component 2. During the rotation to 90 degrees, under the action of the gap between the rotating guide plate 107 and the limit positioning plate 108, the pushing cylinder 305 is pushed to move. Subsequently, the sorting module 3 approaches the testing component 2, and then drives the quartz crystal resonator located at the top of the first sorting component 302 and the second sorting component 303 to approach the connection test port 207. Thus, the quartz crystal resonator can be stuck on the connection test port 207, enabling the connection test port 207 to access the low-power circuit. At this time, the first servo motor 102 stops working, enabling the quartz crystal resonator to continuously access the circuit, thereby testing the quartz crystal resonator and sequentially recording the test results;

[0042] After the test is completed, the first servo motor 102 drives the test component 2 to rotate ninety degrees, and then the first electric push rod 3027 in the first sorting component 302 or the second sorting component 303 where the quartz crystal resonator with unqualified test results is located works to shrink and drives the first clamping plate 3028 to approach the first rotating fixed plate 3021 so as to clamp the pulling rope 3044, and then the second servo motor 3041 drives the rotating pulling shaft 3042 to rotate, and the positioning rope 3043 is connected to rotate and pull the quartz crystal resonator. The rope 3044 is wound around the outer side of the rotating pulling shaft 3042, and then pulls the first sorting component 302 and the second sorting component 303 to rotate, and at the same time drives the quartz crystal resonator located inside the first sorting component 302 and the second sorting component 303 to rotate, so that the unqualified quartz crystal resonator falls to the outside of the device, and then the qualified quartz crystal resonator inside the first sorting component 302 and the second sorting component 303 is taken out, and then the rotating pulling shaft 3042 is driven to rotate in the opposite direction by the second servo motor 3041, and then the first sorting component 3 02. Under the action of the torque spring between the second sorting component 303 and the positioning shaft 3014, the first sorting component 302 and the second sorting component 303 return to their original positions. In the process of removing the unqualified quartz crystal resonator, the pulling rope 3044 corresponding to the position of the qualified quartz crystal resonator will drive the pulling positioning circular plate 3045 to descend during the pulling process, thereby compressing the positioning spring 3046. Then, during the reverse rotation of the rotating pulling shaft 3042, the pulling rope 3044 is pulled under the action of the rebound force of the positioning spring 3046. 044 returns to the original position, can test multiple quartz crystal resonators at the same time, and does not require workers to connect the quartz crystal resonators to the circuit, and can remove unqualified quartz crystal resonators, can automatically test the quartz crystal resonators, the operator only needs to install the quartz crystal resonator to be tested and take out the qualified quartz crystal resonator, which is convenient for testing the quartz crystal resonator. The installation and removal of the quartz crystal resonator can be completed by the mechanical arm, so that the equipment can automatically complete the test of the quartz crystal resonator;

[0043] During the test, the quartz crystal resonators can be installed on both sides of the device and qualified quartz crystal resonators can be taken out, so that the test component 2 can test two groups of quartz crystal resonators at the same time during the rotation. During the test, the quartz crystal resonators can be separated to determine whether they are qualified and the quartz crystal resonators to be tested can be installed on the device, thereby ensuring the test efficiency of the quartz crystal resonators.
