Description

Technical Field

[0001] The invention relates to the technical field of crystal resonator production, in particular to a crystal resonator fine-tuning device. Background Art

[0002] The crystal resonator fine-tuning device is a precision device specially designed to adjust the frequency of a quartz crystal resonator. Since the quartz crystal resonator may have a slight frequency deviation during the production process, or frequency drift due to environmental factors (such as temperature and pressure changes) in actual applications, the existence of the fine-tuning device is to ensure that the frequency of the crystal resonator can be accurately adjusted to the required value. When the crystal resonator fine-tuning device fine-tunes the resonator, a fine-tuning disk is required. The fine-tuning disk plays an important role in the production, quality control and frequency fine-tuning of crystal resonators and high-end electronic equipment. The fine-tuning disk also positions and fixes the crystal resonator to ensure the stability of the crystal during the fine-tuning process and avoid any unnecessary movement or vibration of the crystal resonator.

DETAILED DESCRIPTION

[0029] See also Figure 1-Figure 10 In an embodiment of the present invention, a crystal resonator fine-tuning device includes a fine-tuning disk body 1; a top array of the fine-tuning disk body 1 is provided with a plurality of groups of positioning grooves 3, the positioning grooves 3 are used to place the crystal resonator, a cavity 101 is provided in the side wall of the fine-tuning disk body 1 below the positioning grooves 3, a bearing plate 4 is slidably provided in the positioning grooves 3, a centering component is provided on the periphery of the bearing plate 4, an adsorption component is provided below the bearing plate 4, a through hole 401 for the adsorption component to pass through is provided in the center of the bearing plate 4, a transmission component is provided at the bottom of the bearing plate 4, a transmission connection is made between the transmission component and the adsorption component, and a transmission connection is made between the transmission component and the centering component. When in use, the crystal resonator is placed on the bearing plate 4 in the positioning groove 3 and then pushed downward, so that the bearing plate 4 is in the crystal The crystal resonator moves downward under the push of the body resonator, and when the supporting plate 4 moves downward, the adsorption component is driven to move upward by the transmission component, so that the adsorption component passes through the through hole 401 to complete the adsorption and fixation of the crystal resonator. At the same time, the transmission component will also preferentially drive the centering component to move toward the supporting plate 4, complete the centering work of the crystal resonator and clamp the crystal resonator at the same time, so that the crystal resonator placed in the positioning groove 3 remains in the center of the positioning groove 3, so that the subsequent fine-tuning of the crystal resonator can be carried out smoothly, and the fine-tuning effect of the crystal resonator will not be poor due to offset, and by the coordinated use of the positioning groove 3, the centering component and the adsorption component, the function of fixing the crystal resonator in a single positioning groove 3 is achieved.

[0030] See also Figure 1-Figure 3Preferably, the centering component includes a first positioning plate 5 and a second positioning plate 6; a protective pad can be provided on one side of the first positioning plate 5 and the second positioning plate 6 relative to the supporting plate 4, and a slope is provided on one side of the top of the first positioning plate 5 and the second positioning plate 6, so as to facilitate the placement of the crystal resonator. The first positioning plate 5 and the second positioning plate 6 are symmetrically arranged in two groups along the center of the supporting plate 4, and the first positioning plate 5 and the second positioning plate 6 are slidably fitted with the side of the supporting plate 4, and the bottom of the first positioning plate 5 and the second positioning plate 6 are fixedly provided with a matching block 8, and the bottom of the matching block 8 is provided with a slope facing the cavity 101. In this way, when the supporting plate 4 moves downward to the slope of the matching block 8, the first positioning plate 5 and the second positioning plate 6 will move toward the supporting plate 4, and when the first positioning plate 5 and the second positioning plate 6 move toward the supporting plate 4, the crystal resonator placed on the supporting plate 4 can be centered and clamped, and the first positioning plate 5 and the second positioning plate 6 are slidably connected to the inner wall of the fine-tuning disk body 1 through a round rod.

[0031] See also Figure 1-Figure 3 Preferably, the adsorption component includes an adsorption piece; a fixing seat 13 is slidably provided at the bottom of the adsorption piece, and the bottom of the fixing seat 13 is connected to the bottom of the inner wall of the cavity 101. The fixing seat 13 provides support and guidance for the adsorption piece. The top of the adsorption piece passes through the side wall of the fine-tuning disk body 1 and extends into the positioning groove 3. The two sides of the bottom of the adsorption piece rotate with the transmission component. When the supporting plate 4 moves downward, the supporting plate 4 drives the adsorption piece to move upward through the transmission component. Since there is a gap between the top of the adsorption piece and the supporting plate 4, when the supporting plate 4 moves downward, the supporting plate 4 will preferentially drive the centering component through the transmission component to complete the centering and clamping work of the crystal resonator. Only then will the adsorption piece complete the adsorption and fixing work of the crystal resonator.

[0032] Further, preferably, the adsorbent includes a fixed suction cup 15; an extension groove 153 is provided on the bottom side wall of the fixed suction cup 15, and an extension plate 152 is slidably connected in the extension groove 153, the extension groove 153 and the extension plate 152 are sealed and slidably connected, and a circular hole for ventilation is provided on the outer side of the top of the extension groove 153, so as to avoid the problem that the extension plate 152 and the extension groove 153 cannot move relative to each other due to the existence of air pressure, a base 151 is fixedly provided on the bottom of the extension plate 152, and the bottom sides of the base 151 are rotatably matched with the transmission assembly, a hollow column is provided in the center of the fixed seat 13, and the bottom of the hollow column is connected to the cavity 101, the base 151, the extension plate 152, and the fixed suction cup 15 are all slidably sleeved on the periphery of the hollow column, and the base 151 is sealed and slidably fitted with the periphery of the hollow column, and a spring is provided between the periphery of the extension plate 152 and the extension groove 153.

[0033] When in use, in the initial state where the crystal resonator is not placed in the positioning groove 3, the supporting plate 4 is at the top of the positioning groove 3, the first positioning plate 5 and the second positioning plate 6 are close to the side of the positioning groove 3, and the base 151 is in contact with the top of the fixing seat 13, the top of the extension plate 152 is at the bottom of the extension groove 153, and the fixing suction cup 15 is close to the cavity 101; when the crystal resonator is placed in the positioning groove 3 and pushed downward, the supporting plate 4 moves downward, and the supporting plate 4 moves downward and will first separate from the first positioning plate 5 and the second positioning plate 6 and move to the matching block 8. At this time, the transmission component will act on the matching block 8 to move toward the supporting plate 4, so that the first positioning plate 5 and the second positioning plate 6 move toward the crystal resonator to complete the centering work. At the same time, when the supporting plate 4 moves downward, the base 151 moves upward through the transmission component, and the upward movement of the base 151 pushes the extension plate 152 to move upward, and the extension plate 152 extends upward. The plate 152 moves upward and the extension groove 153 is pushed by the spring to move upward, thereby causing the fixed suction cup 15 to move upward. At this time, the fixed suction cup 15 will move into the through hole 401 and contact the crystal resonator. However, since the crystal resonator may not have completed the centering work, the supporting plate 4 continues to move downward, and the fixed suction cup 15 will move downward. The downward movement of the fixed suction cup 15 causes the extension groove 153 to move toward the extension plate 152. Since there is gas between the fixed suction cup 15, the extension groove 153, the extension plate 152, and the base 151, when the fixed suction cup 15 moves downward, the gas inside it will be discharged through the top of the fixed suction cup 15. Therefore, at this time, the fixed suction cup 15 will not be adsorbed with the crystal resonator, thereby not affecting the centering work of the first positioning plate 5 and the second positioning plate 6. Subsequently, when the first positioning plate 5 and the second positioning plate 6 complete the centering clamping work of the crystal resonator, the fixed suction cup 15 completes the adsorption and fixation.

[0034] See also Figure 1 , Figure 3 , Figure 5 , Figure 7 , Fig.10Preferably, a sealing plate 14 is slidably fitted on the bottom of the fixing seat 13, and a piston 19 is provided on the top of the sealing plate 14. There are multiple groups of pistons 19 arranged in an array on the sealing plate 14, and they all slide and cooperate with the bottom of the hollow column correspondingly. A trigger rod 2 is fixedly provided on the top of one end of the sealing plate 14, and the top of the trigger rod 2 is slidably fitted with the side wall of the fine-tuning disk body 1, and the top of the trigger rod 2 extends to the top of the fine-tuning disk body 1, and the sealing plate 14 is arranged in the cavity 101 and is elastically connected to the cavity 101 by a spring. When in use, in the initial state, the piston 19 extends into the bottom of the hollow column to seal the bottom of the hollow column, and the distance that the piston 19 extends into the bottom of the hollow column is short. When the crystal resonator is fixed, the bottom of the hollow column is blocked, so when the fixed suction cup 15 moves downward, the gas between the hollow column and the fixed suction cup 15 will be discharged from the top of the fixed suction cup 15, and then the negative pressure adsorption function is completed, thereby realizing a single The positioning groove 3 can fix the crystal resonator individually, which solves the problem of adsorbing and fixing the crystal resonators in all the positioning grooves 3 by the overall negative pressure. When the crystal resonator is to be released, it is only necessary to press the trigger rod 2 downward, and the trigger rod 2 moves downward to push the blocking plate 14 to move downward, thereby separating the piston 19 from the hollow column. Since the distance that the piston 19 extends into the hollow column is short and the piston 19 is made of a deformable material, the piston 19 will separate from the hollow column when the blocking plate 14 moves downward, thereby connecting the hollow column cavity 101 to the outside, so that the internal air pressure of the fixed suction cup 15 is restored, and the adsorption effect on the crystal resonator is released. Then the transmission component pushes the carrier plate 4 to move and reset. The movement and reset of the carrier plate 4 will cause the first positioning plate 5, the second positioning plate 6, and the adsorption component to move and reset. Then the movement and reset of the carrier plate 4 will push the crystal resonator thereon to protrude out of the positioning groove 3, thereby facilitating its removal.

[0035] See also Figure 3-Figure 7Preferably, the transmission assembly includes two groups of support rods 9; the bottom end of the support rod 9 is rotatably connected with a telescopic rod 12, and the telescopic rod 12 is arranged in the cavity 101. The two ends of the telescopic rod 12 are arranged with a retractable structure. The end of the telescopic rod 12 away from the support rod 9 is rotatably connected to the base 151, and the two sides of the telescopic rod 12 are rotatably connected to the bottom of the inner wall of the cavity 101 through the column. The column is arranged at the center of the telescopic rod 12 and close to the base 151. The support rod 9 is fixedly arranged at the bottom of the carrying plate 4, and the position of the support rod 9 corresponds to the position of the first positioning plate 5, and the support rod 9 is symmetrically arranged along the center of the carrying plate 4. The end of the support rod 9 away from the carrying plate 4 passes through the side wall of the fine-tuning disk body 1 and extends into the cavity 101, and also provides a guiding and supporting function for the carrying plate 4. In this way, when the carrying plate 4 moves downward, the support rod 9 will move downward, and the base 151 moves upward by pushing the telescopic rod 12. In this process, the end of the telescopic rod 12 close to the support rod 9 will be retracted, and the end away from the support rod 9 will be extended, thereby avoiding the problem of getting stuck.

[0036] Furthermore, preferably, a pressure plate 11 is fixedly provided at the bottom of the support rod 9, and the downward movement of the support rod 9 will push the pressure plate 11 to move downward. An airbag is fixedly provided at the bottom of the pressure plate 11, and the downward movement of the pressure plate 11 will compress the airbag and shrink it. The pressure plate 11 and the airbag are both arranged in the cavity 101, and the pressure plate 11 and the cavity 101 are elastically connected by a spring, and the spring can enable the pressure plate 11 and the support rod 9 to have the function of automatic resetting.

[0037] Furthermore, preferably, a second telescopic tube 18 is fixedly provided at one end of the matching block 8 away from the supporting plate 4, and a first connecting tube 10 is fixedly connected to one end of the second telescopic tube 18 away from the matching block 8. One end of the first connecting tube 10 away from the second telescopic tube 18 passes through the side wall of the fine-tuning disk body 1 and is connected to the airbag. When the airbag is compressed, the gas inside it will enter the first connecting tube 10, and the gas entering the first connecting tube 10 will enter the second telescopic tube 18, causing the second telescopic tube 18 to expand, thereby pushing the matching block 8 to move toward the supporting plate 4. The top of the first connecting tube 10 is fixedly connected to the first telescopic tube 16. When the matching block 8 moves to drive the first positioning plate 5 and the second positioning plate 6 to move to complete the centering and clamping of the crystal resonator, even if the airbag is compressed again, the gas inside it will enter the first telescopic tube 16 through the first connecting tube 10, causing the first telescopic tube 16 to expand. The gas in the airbag that enters the first connecting tube 10 will also enter the second connecting tube 18 corresponding to the second positioning plate 6 through the second connecting tube 17, thereby achieving the effect of synchronous movement of the first positioning plate 5 and the second positioning plate 6; and when the trigger rod 2 is pressed to release the adsorption and fixation of the crystal resonator through the blocking plate 14 and the piston 19, the spring corresponding to the pressure plate 11 will move upward and reset, thereby pushing the support rod 9 and the bearing plate 4 to move and reset, and the movement and rise of the bearing plate 4 will cooperate with the matching block 8 to drive the first positioning plate 5 and the second positioning plate 6 to move and reset in the direction away from the bearing plate 4, and finally the first telescopic tube 16, the second telescopic tube 18 and the pressure plate 11 move and reset for the next use.

[0038] See also Figure 1-Figure 3 , Figure 5 , Figure 8-Figure 9 Preferably, a notch is provided on one side of the top of the supporting plate 4, and the notch is provided at a position close to the first positioning plate 5, and the end of the notch away from the first positioning plate 5 is connected to the through hole 401, and a worm gear 702 is rotatably provided at the center of the end of the notch close to the through hole 401, and a cleaning rod 7 is rotatably provided at the top of the worm gear 702, and a special cleaning piece for wiping and cleaning the crystal resonator is provided on the top of the cleaning rod 7, and the top of the cleaning piece slightly protrudes from the top of the supporting plate 4, so that after the crystal resonator is placed on the supporting plate 4, the cleaning piece can be pressed downward, that is, it fits tightly with the bottom of the crystal resonator.

[0039] Furthermore, preferably, a transmission roller 701 is rotatably provided at one end of the notch near the first positioning plate 5, and the transmission roller 701 and the side wall of the first positioning plate 5 are slidably fitted. When the carrying plate 4 moves downward, the transmission roller 701 cooperates with the first positioning plate 5 and rotates. A worm 703 is meshed and transmitted on the side of the worm wheel 702 near the transmission roller 701. The worm 703 and the transmission roller 701 are connected by a belt transmission. When the transmission roller 701 rotates, the worm 703 is driven to rotate by the belt. The rotation of the worm 703 drives the worm wheel 702 to rotate. The rotation of the worm wheel 702 drives the cleaning rod 7 to rotate. The rotation of the cleaning rod 7 causes the cleaning member to wipe the bottom of the crystal resonator, thereby ensuring that there is no dust or impurities in the contact part of the fixed suction cup 15 with the bottom of the crystal resonator, ensuring the fixation. The fixed suction cup 15 has an adsorption and fixing effect on the crystal resonator. The outer periphery of the worm gear 702 is provided with resistance blocks 704 in a circular array. The resistance blocks 704 are elastically connected to the inner wall of the worm gear 702 through a spring. The inner wall of the cleaning rod 7 is provided with a resistance groove that slides correspondingly with the resistance blocks 704. In this way, when the worm gear 702 rotates, the cleaning rod 7 is first driven to rotate. When the cleaning rod 7 rotates to the edge of the through hole 401 and cannot rotate, the worm gear 702 continues to rotate, which will cause the resistance blocks 704 to slide with the resistance groove, and the resistance blocks 704 are forced to shrink in the side wall of the worm gear 702, thereby not affecting the rotation of the transmission roller 701. When the supporting plate 4 moves upward, the transmission roller 701 rotates in the opposite direction to the supporting plate 4 when it moves downward, so that the cleaning rod 7 rotates and resets, which is convenient for the next use.
