Description

Technical Field

[0001] The utility model relates to the technical field of quartz crystal plate processing, in particular to a diagonal glue dispensing structure for quartz crystal plates. Background Art

[0002] A quartz crystal resonator, also known as quartz crystal or crystal oscillator, is an electronic component that uses the piezoelectric effect of quartz crystal to generate high-precision oscillation frequencies. It is a passive component and can be divided into two types based on the lead conditions: direct-insert (with leads) and surface-mount (without leads).

[0003] The patent document with application number 202323166174.9 discloses a diagonal dispensing structure of a quartz crystal piece for crystal oscillator, a base and a crystal piece body, a protective cover is fixedly installed on the top of the base, a glass cover is installed on the top of the protective cover, a dispensing assembly is provided on the top of the base, two diagonally arranged dispensing seats are fixedly installed on the top of the base, a fixed block is fixedly installed on the top of the dispensing seat, two support grooves are provided at the bottom of the crystal piece body, and a support piece extending into the corresponding support groove is fixedly installed on the surface of the fixed block.

[0004] During the diagonal dispensing process on a quartz wafer, the curing of the conductive adhesive is a critical step, directly impacting the wafer's electrical and mechanical properties. However, due to the limited contact area between the quartz wafer and the dispensing platform, and the potential for a tiny gap, the conductive adhesive struggles to be heated evenly during curing. This uneven curing can significantly degrade the adhesive's electrical and mechanical properties. Specifically, in a vibrating environment, the unevenly cured adhesive can easily crack or peel, leading to unstable current conduction and even crystal oscillation shutdown. Utility Model Content

[0005] The utility model discloses a diagonal dispensing structure for a quartz crystal piece, which aims to solve the problem that the contact area between the quartz crystal chip and the dispensing platform is limited and there may be a tiny gap, which makes it difficult for the conductive glue to be heated evenly during the curing process. This uneven curing may cause the electrical and mechanical properties of the conductive glue to deteriorate significantly. Specifically, in a vibration environment, the unevenly cured conductive glue is prone to cracking or falling off, resulting in unstable current conduction and even causing the crystal oscillator to stop oscillating.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A diagonal dispensing structure for a quartz crystal plate includes a base, wherein the top outer wall of the base is provided with protrusions near the four corners, and the top outer wall of the protrusions is provided with mounting grooves, and further includes:

[0008] Guide mechanism: Located at the top of the base, the guide mechanism includes four dispensing stations, the top outer wall of the dispensing station is provided with a dispensing groove, a first through groove, a second through groove and a pressing assembly installed, the dispensing groove is respectively communicated with the first through groove and the second through groove, the circumferential inner wall of the dispensing groove is provided with two connecting grooves, the inner wall of the connecting groove is provided with four through holes, four of which are communicated with the bottom inner wall of the first through groove, and four of which are communicated with the bottom inner wall of the second through groove, the interior of the dispensing groove is provided with conductive silver glue, and the top outer wall of the dispensing station is provided with a quartz crystal piece body through the conductive silver glue;

[0009] Limiting mechanism: located at the top of the guiding mechanism.

[0010] The above technical solution can increase the contact area between the conductive silver glue and the bottom of the quartz crystal piece body, reduce the generation of gaps, and at the same time enhance the stability and uniformity of the connection between the conductive silver glue and the quartz crystal piece body, improve the conductive performance, and extend its service life. Specifically, during use, the conductive silver glue is placed in the glue dispensing groove, and then the quartz crystal piece body overflows the excess conductive silver glue into the first through groove and the second through groove through the pressing component, so that the conductive silver glue is evenly squeezed or distributed to the four corners of the quartz crystal piece body, increasing the contact area between the conductive silver glue and the bottom of the quartz crystal piece body. Since the connecting groove and the through hole are interconnected, a part of the conductive silver glue can be smoothly guided to flow into the interior of the first through groove and the second through groove to ensure that the conductive silver glue can be evenly distributed or overflow to the required position, so that it can accurately cover the diagonal points to form a stable conductive connection. The four protrusions provided can limit and align the placement position of the quartz crystal piece body.

[0011] In a preferred solution, the depths of the first through groove and the second through groove are less than the depth of the glue dispensing groove, and the depths of the first through groove and the second through groove are the same.

[0012] In this solution, when the conductive silver glue is placed in the glue dispensing groove, part of the conductive silver glue overflows or is squeezed into the first through groove and the second through groove. This design is to control the flow and distribution of the conductive silver glue, avoid excessive overflow or unnecessary waste, and at the same time increase the contact area between the conductive silver glue and the bottom of the quartz crystal piece body, and also help ensure the uniform distribution of the conductive silver glue on the quartz crystal piece body, thereby improving the stability and consistency of the conductive connection.

[0013] In a preferred embodiment, the pressing assembly includes three mounting rods, and a pressure plate is provided on the circumferential outer wall of the three mounting rods. A plurality of equally spaced grid holes are provided on the top outer wall of the pressure plate, and three limiting grooves are provided on the top outer wall of the dispensing table. The mounting rods are inserted into the inner walls of the limiting grooves, and notches are provided on the top outer wall of the pressure plate and in the directions of the two connecting grooves.

[0014] In this solution, the mounting rod is used to fix the pressure plate in an appropriate position and allow it to move vertically to press the conductive silver glue. The grid holes can allow the conductive silver glue to pass through during the pressing process so as to better cover the surface of the quartz crystal piece body. Secondly, the design of the grid holes can increase the contact area between the pressure plate and the conductive silver glue, thereby improving the pressing effect. The notch is designed to allow the conductive silver glue in the connecting groove to flow out more easily into the first through groove and the second through groove during the pressing process. By providing such a channel, it can be ensured that the conductive silver glue can be more evenly distributed on the surface of the quartz crystal piece body.

[0015] As can be seen from the above, the diagonal dispensing structure for quartz crystal pieces includes a base, the top outer wall of the base is provided with protrusions near the four corners, the top outer wall of the protrusions is provided with mounting grooves, and further includes:

[0016] Guide mechanism: Located at the top of the base, the guide mechanism includes four dispensing stations, the top outer wall of the dispensing station is provided with a dispensing groove, a first through groove, a second through groove and a pressing assembly installed, the dispensing groove is respectively communicated with the first through groove and the second through groove, the circumferential inner wall of the dispensing groove is provided with two connecting grooves, the inner wall of the connecting groove is provided with four through holes, four of which are communicated with the bottom inner wall of the first through groove, and four of which are communicated with the bottom inner wall of the second through groove, the interior of the dispensing groove is provided with conductive silver glue, and the top outer wall of the dispensing station is provided with a quartz crystal piece body through the conductive silver glue;

[0017] The limiting mechanism is located at the top of the guide mechanism. The diagonal glue dispensing structure for quartz crystal pieces provided by this utility model has the technical effect of increasing the contact area between the conductive silver glue and the bottom of the quartz crystal piece body, reducing the generation of gaps, and at the same time enhancing the stability and uniformity of the connection between the conductive silver glue and the quartz crystal piece body, improving the conductive performance, and extending its service life.

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application generally described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work fall within the scope of protection of the present application.

[0024] The diagonal dispensing structure for quartz crystal pieces disclosed in the present invention is mainly used when the contact area between the quartz wafer and the dispensing platform is limited and there may be a tiny gap, which makes it difficult for the conductive glue to be heated evenly during the curing process. This uneven curing may cause the electrical and mechanical properties of the conductive glue to deteriorate significantly. Specifically, in a vibration environment, the unevenly cured conductive glue is prone to cracking or falling off, resulting in unstable current conduction and even causing the crystal oscillator to stop oscillating.

[0025] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , a diagonal dispensing structure for a quartz crystal piece, comprising a base 1, a top outer wall of the base 1 having protrusions near the four corners, a top outer wall of the protrusions having mounting grooves 5, and further comprising:

[0026] Guide mechanism: Located at the top of the base 1, the guide mechanism includes four dispensing stations 2. The top outer wall of the dispensing station 2 is provided with a dispensing groove, a first through groove 7, a second through groove 8, and a pressing component installed. The dispensing groove is communicated with the first through groove 7 and the second through groove 8 respectively. The circumferential inner wall of the dispensing groove is provided with two connecting grooves 13. The inner wall of the connecting groove 13 is provided with four through holes 12, four of which are communicated with the bottom inner wall of the first through groove 7, and four of which are communicated with the bottom inner wall of the second through groove 8. Conductive silver glue is provided inside the dispensing groove, and a quartz crystal piece body 3 is provided on the top outer wall of the dispensing station 2 through the conductive silver glue;

[0027] Limiting mechanism: located at the top of the guide mechanism.

[0028] Among them, the depth of the first through groove 7 and the second through groove 8 is less than the depth of the glue dispensing groove, and the depth of the first through groove 7 and the second through groove 8 is the same. When the conductive silver glue is placed in the glue dispensing groove, part of the conductive silver glue overflows or is squeezed into the first through groove 7 and the second through groove 8. This design is to control the flow and distribution of the conductive silver glue, avoid excessive overflow or unnecessary waste, and at the same time increase the contact area between the conductive silver glue and the bottom of the quartz crystal piece body 3, and also help to ensure the uniform distribution of the conductive silver glue on the quartz crystal piece body 3, thereby improving the stability and consistency of the conductive connection.

[0029] During the specific implementation process, the first through-groove 7 and the second through-groove 8 are distributed perpendicular to each other, and the glue dispensing groove is located between the first through-groove 7 and the second through-groove 8, which helps to provide two mutually perpendicular flow directions for the conductive silver glue during the glue dispensing process, thereby ensuring that the conductive silver glue can more evenly cover the surface of the quartz crystal piece body 3. Secondly, the vertical distribution can reduce stress concentration on the structure and improve the overall stability and reliability. At the same time, the conductive silver glue can be evenly distributed to the four corners of the quartz crystal piece body 3, thereby forming a stable conductive connection.

[0030] Among them, the inner corners of the protrusion close to the quartz crystal plate body 3 are rounded, which can reduce the friction and wear between the quartz crystal plate body 3 and the protrusion. In a long-term vibration or impact environment, sharp corners may scratch or wear the surface of the quartz crystal plate body 3, thereby affecting the stability and reliability of the conductive connection. By adopting a rounded corner design, this risk can be significantly reduced, ensuring the long-term stability of the conductive connection.

[0031] Specifically, when in use, the conductive silver glue is placed in the glue dispensing groove, and then the quartz crystal piece body 3 overflows the excess conductive silver glue into the first through groove 7 and the second through groove 8 through the pressing component. When the pressing component reaches the bottom of the glue dispensing groove, the conductive silver glue is evenly squeezed or distributed to the four corner points of the quartz crystal piece body 3, thereby increasing the contact area between the conductive silver glue and the bottom of the quartz crystal piece body 3. Since the connecting groove 13 and the through hole 12 are interconnected, a part of the conductive silver glue can pass through the additional connecting groove 13 and the through hole 12 when squeezed by the pressing component. The channel smoothly guides it to flow into the first through groove 7 and the second through groove 8 to ensure that the conductive silver glue can be evenly distributed or overflow to the required position, so that it can accurately cover the diagonal points to form a stable conductive connection. The four protrusions provided can limit and align the placement position of the quartz crystal piece body 3. This device can increase the contact area between the conductive silver glue and the bottom of the quartz crystal piece body 3, reduce the generation of gaps, and at the same time enhance the stability and uniformity of the connection between the conductive silver glue and the quartz crystal piece body 3, improve the conductive performance, and extend its service life.

[0032] Reference Figure 3 In a preferred embodiment, the pressing assembly includes three mounting rods 10, and a pressure plate 9 is provided on the circumferential outer wall of the three mounting rods 10. The top outer wall of the pressure plate 9 is provided with a plurality of equally spaced grid holes, and the top outer wall of the dispensing station 2 is provided with three limiting grooves 11. The mounting rods 10 are inserted into the inner wall of the limiting groove 11, and notches are provided on the top outer wall of the pressure plate 9 and in the direction of the two connecting grooves 13.

[0033] Among them, a limiting ring 6 is provided on the top outer wall of the dispensing table 2 and between two adjacent limiting grooves 11, between the limiting groove 11 and the first through groove 7, and between the limiting groove 11 and the second through groove 8. The main function of the limiting ring 6 is to prevent the conductive silver glue from overflowing from the predetermined flow path during the pressing process. When the pressing plate 9 applies pressure to the conductive silver glue, the conductive silver glue will be squeezed to the four sides of the dispensing groove and try to flow out through any possible gaps. However, due to the presence of the limiting ring 6, these gaps are effectively closed, thereby ensuring that the conductive silver glue can only flow along the predetermined channels, namely the connecting groove 13, the first through groove 7 and the second through groove 8.

[0034] Specifically, the mounting rod 10 is used to fix the pressing plate 9 in an appropriate position and allow it to move in the vertical direction to press the conductive silver glue. The grid holes can allow the conductive silver glue to pass through during the pressing process so as to better cover the surface of the quartz crystal piece body 3. Secondly, the design of the grid holes can increase the contact area between the pressing plate 9 and the conductive silver glue, thereby improving the pressing effect. The notch is designed to allow the conductive silver glue in the connecting groove 13 to flow out more easily into the first through groove 7 and the second through groove 8 during the pressing process. By providing such a channel, it can be ensured that the conductive silver glue can be more evenly distributed on the surface of the quartz crystal piece body 3.

[0035] Reference Figure 1 In a preferred embodiment, the limiting mechanism includes a mounting cover 4, the top inner wall of the mounting cover 4 is provided with an extrusion block, the bottom outer wall of the mounting cover 4 is provided with a connecting frame 14 near the four corners, the mounting groove 5 and the top outer wall of the connecting frame 14 are each provided with four screw holes 15, the connecting frame 14 is adapted to the mounting groove 5, and the mounting cover 4 is fixedly connected to the four mounting grooves 5 by bolts.

[0036] Specifically, the connecting frames 14 at the four corners of the mounting cover 4 are fixed to the mounting grooves 5 on the base 1 by bolts. The provided mounting cover 4 can improve the protective effect of the quartz crystal piece body 3 and prevent the quartz crystal piece body 3 from being damaged. In the specific implementation process, the extrusion block can be made of rubber material. The extrusion block can better fit the surface of the conductive silver glue during the pressing process, thereby achieving more uniform and effective pressing of the conductive silver glue, while reducing the impact of vibration on the quartz crystal piece body 3.

[0037] Working principle: When in use, the conductive silver glue is placed in the glue dispensing groove, and then the quartz crystal piece body 3 overflows the excess conductive silver glue into the first through groove 7 and the second through groove 8 through the pressing component. When the pressing component reaches the bottom of the glue dispensing groove, the conductive silver glue is evenly squeezed or distributed to the four corner points of the quartz crystal piece body 3, thereby increasing the contact area between the conductive silver glue and the bottom of the quartz crystal piece body 3. Since the connecting groove 13 and the through hole 12 are interconnected, a part of the conductive silver glue can be smoothly guided into the interior of the first through groove 7 and the second through groove 8 through the additional channel of the connecting groove 13 and the through hole 12 when squeezed by the pressing component, ensuring that the conductive silver glue can be evenly distributed or overflow to the required position, so that it can accurately cover the diagonal points to form a stable conductive connection.

The replacements described may be partial structures, devices, or method steps, or they may be complete technical solutions. Any equivalent replacements or modifications based on the technical solution and the concept of the present invention shall be covered by the scope of protection of the present invention.
