Description

Technical Field

[0001] The utility model relates to the field of electronic testing equipment, in particular to an all-in-one final inspection and testing machine for quartz crystal resonators. Background Art

[0002] Quartz crystal is a material with high stability and excellent frequency response characteristics. Its unique piezoelectric effect makes it an ideal choice for manufacturing high-precision resonators. Quartz crystal resonators are widely used in various electronic devices such as timers, oscillators, and communications equipment to provide a stable frequency reference. During the resonator manufacturing process, accurate testing of its frequency characteristics, stability, and the thickness of the electroplating layer, such as nickel and gold plating on copper substrates, is crucial. These parameters directly determine the performance and reliability of the resonator.

[0003] Resonator inspection, particularly measuring the plating thickness, is a critical step in ensuring product quality. The plating not only affects the resonator's electrical performance but also its corrosion resistance and service life. Therefore, developing equipment that can efficiently and accurately measure the plating thickness of quartz crystal resonators is crucial for improving product performance and production efficiency.

[0004] In the existing desktop spectrometer thickness gauge inspection process, due to the tiny size of the quartz crystal resonator, the operator usually needs to use precision tweezers to place it within the measurement area of ​​the inspection machine. Due to the small size of the crystal, the inspector needs to manually adjust the position of the lens and use a microscope or high-resolution camera to find and focus on the specific electroplated area on the quartz crystal. This step is not only cumbersome, but also requires turning the lens knob many times, increasing the uncertainty and time cost of the inspection. Multiple fine-tuning of the lens position increases the inspection time and reduces the overall inspection efficiency. Utility Model Content

DETAILED DESCRIPTION

[0020] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0021] Example: Quartz crystal resonator final inspection and testing all-in-one machine, such as Figure 1-Figure 5 As shown, it includes a detection machine 1, a detection base plate 2, an outer frame 3, a first electric slide rail 4, a second electric slide rail 5, a horizontal push plate 6 and a longitudinal limit assembly. The detection base plate 2 is provided in the detection machine 1. The outer frame 3 is connected to the front and rear sides of the detection base plate 2. The outer frame 3 is used to preliminarily limit the position of the quartz crystal resonator so that it will not leave the detection base plate 2. The first electric slide rail 4 and the second electric slide rail 5 are installed in the detection machine 1. The first electric slide rail 4 and the second electric slide rail 5 are located on the front and rear sides of the detection base plate 2. The front, back, left and right positions are all referenced. Figure 1 The first electric slide rail 4 is located at the left end of the second electric slide rail 5. The slide rails between the first electric slide rail 4 and the second electric slide rail 5 are not connected. The first electric slide rail 4 and the second electric slide rail 5 are connected with a horizontal push plate 6. The horizontal push plate 6 is slidably connected to the outer frame 3. A longitudinal limit assembly is provided on the left end horizontal push plate 6. The longitudinal limit assembly is used to push the quartz crystal resonator from the front and back directions.

[0022] like Figure 2 、 Figure 4 and Figure 5 As shown, the longitudinal limit assembly includes a fixed block 7, a motor 8, a bidirectional screw 9, a longitudinal push plate 10, an adjusting slide rail 12, a movable plate 13 and an adjusting screw 14. The horizontal push plate 6 at the left end is connected to the fixed block 7, and the motor 8 is installed on the fixed block 7. The horizontal push plate 6 at the left end is rotatably connected to the bidirectional screw 9, one end of the bidirectional screw 9 is connected to the output shaft of the motor 8, and two longitudinal push plates 10 are threadedly connected to the bidirectional screw 9. The movable plate 13 is provided with an adjusting slide rail 12, and the movable plate 13 is slidably connected to the longitudinal push plate 10 through the adjusting slide rail 12. The longitudinal push plate 10 is threadedly connected to the adjusting screw 14, and the bottom of the adjusting screw 14 is squeezed and fitted with the movable plate 13.

[0023] After the inspector places the quartz crystal resonator to be inspected on the inspection base plate 2, the first electric slide rail 4 and the second electric slide rail 5 are turned on. The first electric slide rail 4 and the second electric slide rail 5 drive the horizontal push plate 6 to move toward the middle, thereby pushing the quartz crystal resonator to move toward the middle. When the two horizontal push plates 6 are close to each other, the quartz crystal resonator is basically located in the middle in terms of left and right positions. Due to the restrictions of the longitudinal push plate 10 and the movable plate 13 in the longitudinal limit assembly, the two horizontal push plates 6 will not fit together. After the horizontal push plate 6 on the right side contacts the longitudinal limit assembly, the first electric slide rail 4 and the second electric slide rail 5 are closed, and the quartz crystal resonator is further moved through the longitudinal limit assembly to be further centered.

[0024] After closing the first electric slide 4 and the second electric slide 5, turn on the motor 8, the motor 8 drives the bidirectional screw 9 to rotate, the bidirectional screw 9 drives the two longitudinal push plates 10 to move toward the middle, the longitudinal push plate 10 drives the movable plate 13 to move together, and the right end of the movable plate 13 slides and rubs with the transverse push plate 6 to ensure that the quartz crystal resonator is located between the two movable plates 13. As the two longitudinal push plates 10 gradually approach, the quartz crystal resonator is gradually centered in the front and rear directions. Finally, the quartz crystal resonator to be tested is basically located at the center point of the test base plate 2. At this time, the inspector then manually adjusts the position of the lens to ensure that it is aligned with the quartz crystal resonator to be tested, turns on the detection machine 1, and detects the quartz crystal resonator. After being pushed by the transverse push plate 6 and the longitudinal push plate 10, the range that needs to be adjusted is small, and the setting It saves time in adjusting the lens and improves the detection efficiency. After the detection, the quartz crystal resonator is taken out. At the same time, the inspector rotates the adjusting screw 14 to adjust the position of the movable plate 13 left and right. The movable plate 13 slides on the longitudinal push plate 10 by adjusting the slide rail 12. The extended length of the movable plate 13 is adjusted to adjust the working area of ​​the longitudinal push plate 10. The slide rails of the first electric slide rail 4 and the second electric slide rail 5 are not connected, and thus there is a gap between the first electric slide rail 4 and the second electric slide rail 5. The adjustable movable plate 13 can meet the adjustment of the first electric slide rail 4 and the second electric slide rail 5, so that the first electric slide rail 4 and the second electric slide rail 5 maintain a stable moving stroke when moving the horizontal push plate 6. After adjusting the movable plate 13, tighten the adjusting screw 14 to squeeze and fix the movable plate 13.

[0025] like Figure 4 and Figure 5 As shown, a protective pad 11 is further included, and the bottom of one side adjacent to the two movable plates 13 is connected to the protective pad 11.

[0026] The protective pad 11 is in contact with the quartz crystal resonator to protect the properties of the quartz crystal resonator during the process of moving the quartz crystal resonator.

[0027] like Figure 4As shown, a fastening rubber pad 17 is also included. The bottom of the adjusting screw 14 is connected to the fastening rubber pad 17, and the fastening rubber pad 17 is squeezed and fitted with the moving plate 13.

[0028] like Figure 4 and Figure 5 As shown, a handle 15 is further included, and the movable plate 13 is connected to the handle 15 .

[0029] When fixing the movable plate 13, the fastening rubber pad 17 is squeezed by the adjusting screw 14 and the movable plate 13. The resilience of the fastening rubber pad 17 makes the adjusting screw 14 fit closely with the longitudinal push plate 10, and also ensures the friction between it and the movable plate 13, further improving the stability of the movable plate 13 after fixation.

[0030] like Figure 4 As shown, the movable plate 13 further includes a scale 16 , and the scale 16 is provided on the movable plate 13 .

[0031] When adjusting the position of the movable plate 13 , the scale 16 on the surface can be referred to ensure that the positions of the movable plates 13 on both sides are the same. Adjustment through the handle 15 is more convenient for the inspector to operate.

[0032] The inspector places the quartz crystal resonator on the inspection base plate 2, starts the first electric slide 4 and the second electric slide 5, and pushes the horizontal push plate 6 to center the quartz crystal resonator in the left and right directions. Then, the motor 8 drives the bidirectional screw 9, which drives the longitudinal push plate 10 and the movable plate 13 to move, ensuring that the quartz crystal resonator is also centered in the front and back directions. During this process, the position of the movable plate 13 can be adjusted by adjusting the screw 14 and the adjusting slide 12, and the scale 16 is used to ensure that the positions of both sides are consistent. The protective pad 11 protects the quartz crystal resonator, and the tightening rubber pad 17 enhances the stability of the movable plate 13. Finally, the inspector manually adjusts the lens to aim at the quartz crystal resonator for inspection.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
