[0034] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0035] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] like Figures 1-13 As shown, this utility model embodiment provides a quartz crystal clamping mechanism, including a bottom mounting plate 1 and an L-shaped support plate 2. The bottom mounting plate 1 is provided with a linear guide rail, and the linear guide rail is connected to a transmission component. A circuit connection plate is connected above the transmission component, and the circuit connection plate is connected to a vertically arranged circuit board. Multiple sets of probes are provided on one side of the circuit board, and each set of probes includes two probe 9 units. The L-shaped support plate 2 is provided on the bottom mounting plate 1, and a test seat 4 mounting plate 3 is provided at the top of the L-shaped support plate 2. A test seat 4 is provided on the test seat 4 mounting plate 3, and a plurality of detection slots 5 are provided on the test seat 4. The test seat 4 is perpendicular to the linear guide rail.

[0037] The bottom mounting plate 1 provides basic support, the linear guide rail enables precise linear movement, the transmission component drives the movement, the circuit connection plate connects to the vertically set circuit board, the probe 9 on the circuit board is used to clamp and test the quartz crystal, the L-shaped support plate 2 is fixed on the bottom mounting plate 1, supports the test seat 4 mounting plate 3, the test seat 4 has a test groove 5 to place the quartz crystal, the test seat 4 is perpendicular to the linear guide rail to ensure alignment and stability, the overall mechanism components work together to achieve clamping and testing of the quartz crystal.

[0038] The quartz crystal clamping mechanism of this utility model provides a rigid support base through an L-shaped support plate 2, combined with a test seat 4 and a detection groove 5 that are perpendicular to the linear guide rail, ensuring stable positioning of the quartz crystal. At the same time, the use of a vertically arranged circuit board and a single structure of each set of dual probes 9 forms symmetrical force during clamping, effectively resisting the vibration influence generated by the transmission components, thereby significantly eliminating the risk of quartz crystal shaking or falling during the detection process, improving detection accuracy and operational reliability.

[0039] Furthermore, such as Figure 6 and Figure 7 As shown, a plurality of detection slots 5 are located at the middle position of the upper surface of the test base 4, and the plurality of detection slots 5 are arranged sequentially at fixed intervals. The plurality of detection slots 5 are connected in the longitudinal direction by a first groove 6, and each detection slot 5 has a second groove 7 on both sides.

[0040] Furthermore, the mechanism also includes a through-beam fiber mounting block 28, which is disposed on the L-shaped support plate 2.

[0041] Understandably, there are two L-shaped support plates 2 and two through-beam fiber mounting blocks 28, located on both sides of the mechanism.

[0042] Understandably, the first groove 6 is used to cooperate with the through-beam optical fiber, which is used to detect the position or alignment of the quartz crystal. The through-beam optical fiber mounting block 28 integrates an optical fiber sensor to provide real-time feedback control.

[0043] Understandably, the second groove 7 is used to cooperate with the probe 9. The probes 9 on both sides of the test seat 4 reach the detection groove 5 through the second groove 7 to clamp and fix the quartz crystal.

[0044] Furthermore, the circuit board is connected to a probe guide plate 8, which is located on the side of the circuit board where the probe 9 is located. The probe guide plate 8 has a pinhole 10 corresponding to the probe 9, and the probe 9 passes through the pinhole 10 and points to the detection groove 5.

[0045] The probe guide plate 8 reduces the deviation of the probe 9 through mechanical constraints, directly improving the clamping stability of the quartz crystal, avoiding shaking when the probe 9 contacts the crystal, ensuring the reliability of the testing process, and reducing the false detection rate.

[0046] Furthermore, the linear guide rail includes a first linear guide rail 11 and a second linear guide rail 12, the transmission assembly includes a first transmission assembly 13 and a second transmission assembly 14, and the circuit board includes a first circuit board 15 and a second circuit board 16.

[0047] The first transmission component 13 is connected to the first linear guide rail 11 and the second linear guide rail 12, and the first circuit board 15 is connected to the first transmission component 13 through the first circuit connection board 17.

[0048] The second transmission component 14 is connected to the first linear guide rail 11 and the second linear guide rail 12, and the second circuit board 16 is connected to the second transmission component 14 through the second circuit connection board 18.

[0049] Furthermore, such as Figure 8 and Figure 9 As shown, the first transmission assembly 13 includes a guide rail mounting plate 19 and a slider. The slider includes a first slider 20 and a second slider 21. The first slider 20 is disposed on the first linear guide rail 11, and the second slider 21 is disposed on the second linear guide rail 12. The two ends of the lower surface of the guide rail mounting plate 19 are respectively connected to the first slider 20 and the second slider 21.

[0050] The slider provides smooth sliding, and the guide rail mounting plate 19 forms a stable platform. The slider design absorbs and reduces mechanical vibration, and the guide rail mounting plate 19 ensures smooth movement, directly suppressing the risk of quartz crystal wobbling, enhancing clamping stability, and extending equipment life.

[0051] Furthermore, the guide rail mounting plate 19 is linear, and a Y-direction adjusting plate 22 is provided at the middle position of the upper surface of the guide rail mounting plate 19. The Y-direction adjusting plate 22 is connected to the Z-direction adjusting plate 24 through the third slider 23.

[0052] This utility model's multi-directional adjustment plate provides precise position control, adapts to quartz crystals of different sizes, reduces mechanical stress caused by specification mismatch, lowers vibration, and improves crystal stability during testing.

[0053] Furthermore, the Z-direction adjustment plate 24 is horizontally arranged, and an angle adjustment plate 25 is connected to the upper surface of the Z-direction adjustment plate 24. One end of the angle adjustment plate 25 is connected to the first circuit connection plate 17.

[0054] like Figure 8As shown, the angle adjustment plate 25 has several holes, which connect it to the Z-direction adjustment plate 24. The circular holes are used for mounting and positioning, while the arc-shaped holes are used for angle adjustment. Angle adjustment enables precise alignment of the probe 9, reducing vibration and crystal wobble caused by deviation; it also improves clamping stability, ensuring a stable and reliable testing process.

[0055] Furthermore, the structure of the second transmission component 14 is the same as that of the first transmission component 13, and will not be described again here. This utility model features a standardized design that simplifies manufacturing, ensures system balance, reduces asymmetric vibration sources, thereby suppressing the vibration influence of the quartz crystal as a whole, and improving stability and consistency.

[0056] Furthermore, such as Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, probes 9 are provided on both the first circuit board 15 and the second circuit board 16. The probes 9 are located at the upper edges of the first circuit board 15 and the second circuit board 16, and the sides of the first circuit board 15 and the second circuit board 16 with probes 9 are arranged opposite each other.

[0057] Understandably, multiple detection slots 5 are used to place quartz crystals. Each quartz crystal has a probe group on each side. Each probe group has two probe units, meaning that a quartz crystal is held by four probes 9. At the same time, the edge probe layout and relative design enhance the holding force, directly resisting crystal shaking caused by mechanical vibration, improving detection stability, and supporting efficient parallel operation.

[0058] Furthermore, a rectangular window 26 is provided on the bottom mounting plate 1, the rectangular window 26 is located in the middle of the bottom mounting plate 1, and a cam 27 is connected to the lower surface of the guide rail mounting plate 19.

[0059] like Figure 5 As shown, within the rectangular window 26 of the bottom mounting plate 1, the cam 27 controls the relative movement of the first transmission component 13 and the second transmission component 14 through mechanical linkage, thereby realizing the clamping of the probe 9 on the quartz crystal. For example, the motor drives the cam 27 to make the probe 9 on the first circuit board 15 and the second circuit board 16 move relative to each other to move closer or further apart (corresponding to clamping or opening), thus realizing automated operation.

[0060] In one embodiment, the motor drives the cam 27, which in turn drives the transmission assembly. Through mechanical linkage, the probes on the first circuit board 15 and the probes 9 on the second circuit board 16 move relative to each other, causing the probes 9 on both sides to open. After the transfer mechanism's suction nozzle releases the material, the probes 9 on both sides move closer together and clamp. The oscillation circuit in the circuit board, through the crystal, plays the role of electro-cleaning.

[0061] This invention improves upon the existing quartz crystal stability by integrating a dual linear guide rail system, a probe guide plate 8, a multi-directional adjustment plate, a cam 27 drive, and an optimized detection slot 5 layout. By reducing vibration of moving parts, enhancing clamping force, and implementing automated control, it significantly improves the stability and reliability of the detection process, preventing crystal displacement or drop during testing and promoting the development of quartz crystal detection towards high stability and high precision automation.
