Technical Field

[0001] The utility model specifically relates to a crystal frequency piece quality detection device, belonging to the technical field of crystal frequency piece detection equipment. Background Art

[0002] A crystal frequency piece is a resonant element made by using the piezoelectric effect of a crystal. When used together with semiconductor devices and resistor-capacitor elements, a crystal oscillator can be formed. A quartz crystal oscillator is a common crystal oscillator. Due to its high precision and high stability, it is widely used in various oscillation circuits such as color TVs, computers, and remote controls. The quality detection of crystal frequency pieces is one of the important steps in the production process, and a crystal frequency piece quality detection device is needed to ensure that the crystal frequency piece can be used normally.

[0003] For example, the publication number is: CN211321303U, a detection device for quartz crystal frequency pieces, which relates to the technical field of resonator production and manufacturing, including a detection frame. The detection frame is a U-shaped composed of two cross plates and a vertical plate. A frequency pickup is fixedly connected to the vertical plate of the detection frame, and two mounting plates are respectively fixedly connected to the opposite surfaces of the two cross plates of the detection frame; a ball screw module is arranged on the two mounting plates at the upper end of the detection frame, and a guide rod is arranged on the two mounting plates at the lower end of the detection frame; a U-shaped support frame is fixedly connected to the sliding plate, and the upper end of the support frame is fixedly connected to the ball nut of the ball screw module; a hydraulic cylinder is fixedly connected to the upper end of the support frame, a servo motor is fixedly connected to the lower end of the support frame, a turntable is rotatably connected to the piston rod of the hydraulic cylinder, and a turntable is fixedly connected to the output shaft of the servo motor; a fine-tuning gun head is arranged on the bottom plate, and a fine-tuning gun head knob is fixed at the end of the fine-tuning gun head, which has the advantages of convenient use, high detection efficiency, and high safety.

[0004] When a common crystal frequency piece quality detection device is in use, it can drive the crystal frequency piece to move through the setting of a ball screw to make it enter the detection range of the frequency pickup for detection. Moreover, the crystal frequency piece can be clamped by a hydraulic cylinder, and then the quartz crystal can be driven to rotate by a servo motor for comprehensive detection. However, when the servo motor drives the turntable to rotate, the turntables may be misaligned, thereby damaging the crystal frequency piece. The crystal frequency piece is also easily damaged when being clamped and fixed, and when the crystal frequency piece is being detected, it is inconvenient to place and collect, and the detection efficiency is low.

[0012] Further, in order to enable the square plate to slide, a square groove is formed at the upper end of the second gear, the square plate is clamped in the square groove, an installation groove is formed at the lower end of the square plate, a rack is fixedly installed in the installation groove. During use, the square plate can move in the square groove, facilitating the picking and placing of the crystal frequency chip, and the size of the rack matches the size of the installation groove.

[0013] Further, in order to enable the rack to move, a second motor is fixedly installed inside the second gear on one side of the square groove, a rotating shaft with a fourth gear at one end is fixedly installed at the output end of the second motor, and the fourth gear meshes with the rack. During use, the second motor is a servo motor that can rotate forward and backward to drive the fourth gear to rotate forward and backward.

Detailed Embodiments

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 As shown, a crystal frequency chip quality detection device includes a base 1 and a frequency pickup 2. The frequency pickup 2 is fixedly installed on one side of the upper end of the base 1. An L-shaped plate 3 is fixedly installed on one side of the upper end of the base 1. A cylinder 4 is fixedly installed at one end of the L-shaped plate 3. The output end of the cylinder 4 is rotatably installed with a first gear 5. A buffer protection component 6 is installed at the lower end of the first gear 5. A support column 7 is fixedly installed on the upper end of the base 1 below the first gear 5. A second gear 8 is rotatably installed at the upper end of the support column 7. A movable square plate 9 is installed inside the upper end of the second gear 8. A plain bearing 10 is fixedly installed at the middle position of the upper end of the first gear 5. The output end of the cylinder 4 is fixedly connected to the inner end of the plain bearing 10. When in use, first move out the square plate 9, place the crystal frequency chip on the square plate 9, then reset the square plate 9, and then start the cylinder 4 to move the first gear 5 downward to clamp and fix the crystal frequency chip. At this time, the buffer protection component 6 protects the crystal frequency chip, and at the same time rotate the first gear 5 and the second gear 8 to comprehensively detect the crystal frequency chip.

[0022] The buffer protection component 6 includes a telescopic rod 601. One end of the telescopic rod 601 is fixedly installed at the lower end of the first gear 5. A fixing plate 602 is fixedly installed at the free end of the telescopic rod 601. One end of the fixing plate 602 is provided with a rubber pad. A spring 603 is sleeved outside the telescopic rod 601. One end of the spring 603 is fixedly connected to the first gear 5, and the other end of the spring 603 is fixedly connected to the fixing plate 602. A first motor 11 is fixedly installed at one end of the L-shaped plate 3. The output end of the first motor 11 is fixedly installed with a third gear 12, and the third gear 12 meshes with the first gear 5 and the second gear 8. The height of the third gear 12 is greater than the sum of the heights of the first gear 5 and the second gear 8. When in use, the first gear 5 drives the fixing plate 602 to move downward to fix the crystal frequency chip. When the pressure brought by the fixing plate 602 is too large, under the action of the spring 603, the telescopic rod 601 contracts, and the elastic force of the spring 603 is used for buffer protection. Then start the first motor 11 to drive the third gear 12 to rotate, so as to drive the first gear 5 and the second gear 8 to rotate at the same time.

[0023] A square groove is formed at the upper end of the second gear 8. The square plate 9 is clamped in the square groove. An installation groove is formed at the lower end of the square plate 9. A rack 13 is fixedly installed in the installation groove. A second motor 14 is fixedly installed inside the second gear 8 on one side of the square groove. The output end of the second motor 14 is fixedly installed with a rotating shaft provided with a fourth gear 15 at one end, and the fourth gear 15 meshes with the rack 13. During use, the second motor 14 is started to drive the fourth gear 15 to rotate, and the rack 13 moves accordingly, causing the square plate 9 to move in the square groove, thereby moving the square plate 9 out, facilitating the picking and placing of the crystal frequency chip.

[0024] When the present utility model is in use, first, the second motor 14 is started to move out the square plate 9. Then, the crystal frequency chip is placed on the square plate 9. Next, the square plate 9 is reset to achieve the placement and collection of the crystal frequency chip. The operation is convenient, labor is saved, and the detection efficiency is improved. Then, the air cylinder 4 is started to move the first gear 5 downward to clamp and fix the crystal frequency chip. Then, the first motor 11 is started to drive the first gear 5 and the second gear 8 to rotate simultaneously to comprehensively detect the crystal frequency chip, preventing the first gear 5 and the second gear 8 from being misaligned during rotation, thereby damaging the crystal frequency chip. At the same time, the pressure brought by the spring 603 buffer fixing plate 602 to the crystal frequency chip is buffered to prevent damage to the crystal frequency chip caused by excessive pressure.
