Description

Technical Field

[0001] This application relates to the field of quartz crystal resonator technology, and in particular to a tuning fork type quartz crystal resonator lead expansion device and process. Background Technology

[0002] A quartz crystal resonator, also known as a quartz crystal or crystal oscillator, is an electronic component that uses the piezoelectric effect to generate a high-precision oscillation frequency. A tuning fork type quartz crystal resonator, in addition to having the electrical characteristics of a quartz crystal resonator, also has the appearance and structure of a tuning fork.

[0003] The main body of a quartz crystal resonator is a quartz crystal wafer. Because the quartz crystal wafer is too thin and easily oxidized, in the manufacturing process, the wafer is usually placed in a base, and then the base is sealed in a nitrogen-protected or vacuum environment; conductive adhesive is used to connect the wafer to the base.

[0004] Quartz crystal resonators can be classified into two types based on their lead configuration: through-hole (with leads) and surface mount (without leads).

[0005] A tuning fork quartz crystal resonator includes a base and two pins extending parallel to each other from the same side of the base. The base is surrounded by a housing. In some applications, it is necessary to enlarge the pins of the tuning fork quartz crystal resonator. In the present technology, the pin enlargement is often done manually, and there is no automated pin enlargement equipment. Summary of the Invention

[0051] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0052] Example 1

[0053] Combination Figures 1 to 13To further illustrate this embodiment, a tuning fork type quartz crystal resonator lead expansion device includes:

[0054] The base plate assembly 2 is used to support the tuning fork type quartz crystal resonator 4 at equal intervals; the base plate assembly is provided with equally spaced notches 202 for accommodating the base shell of the tuning fork type quartz crystal resonator, and a plurality of first cylindrical holes 203 corresponding to the positions of the notches, the first cylindrical holes being vertically downward.

[0055] Conveyor line 1 is used for automatically conveying the base plate assembly 2;

[0056] An automatic arrangement device is used to automatically arrange random tuning fork quartz crystal resonators at equal intervals on the base plate assembly 2;

[0057] Automatic lead expansion device 5 is used to automatically expand the leads of the tuning fork type quartz crystal resonators that are arranged at equal intervals on the base plate assembly.

[0058] See also Figures 1-3 The automatic arrangement equipment includes a vibrating feeder and a discharge guide rail. The base plate assembly 2 is placed on the conveyor line 1 and is horizontally positioned at the lower end of the discharge guide rail. The base plate assembly carries tuning fork-type quartz crystal resonators that exit from the discharge guide rail. The vibrating feeder is used to discharge the randomly arranged tuning fork-type quartz crystal resonators in a vertically arranged sequence. The discharge guide rail is used to convey the vertically arranged tuning fork-type quartz crystal resonators to the base plate assembly 2. With the cooperation of the conveyor line, the tuning fork-type quartz crystal resonators are arranged horizontally at equal intervals on the base plate assembly.

[0059] The vibratory feeder includes a vibratory plate base 302 and a vibratory plate 301. The vibratory plate has a first guide groove 307 for accommodating a series of tuning fork quartz crystal resonators arranged in a single order. The vibratory plate also has a second guide groove 308 that transitions from an inclined state to a vertical state. The second guide groove 308 is located at the discharge end of the first guide groove 307. One side of the second guide groove 308 is connected to the first guide groove 307, and the other side of the second guide groove 308 is connected to the unloading guide rail.

[0060] See Figure 14 The second guide groove 308 and the first guide groove 307 are inclined along the inner surface of the vibratory feeder 301 at the connection point. (See reference...) Figure 14 As can be seen from the perspective view, the second guide groove 308 gradually changes from an inclined state to a vertical state to connect with the vertically arranged third guide groove in the material feeding connecting guide rail. Figure 14 This is only for understanding the shape of the second guide groove, not for understanding the shape and size of the third guide groove.

[0061] See Figure 14 In order to facilitate the transition of the tuning fork-type quartz crystal resonator from an inclined state to a vertical state within the second guide groove 308, an inverted groove is provided on the inclined side of the second guide groove 308, and the size of the second guide groove 308 is larger than the size of the tuning fork-type quartz crystal resonator; the tuning fork-type quartz crystal resonator is supported by the inverted groove on the inclined side of the second guide groove 308, and transitions from an inclined state to a vertical state along the second guide groove.

[0062] Tuning fork-type quartz crystal resonators are randomly placed inside the vibrating plate 301. Due to the vibration of the vibrating plate base 302, the tuning fork-type quartz crystal resonators enter the first guide groove and spiral upward. The tuning fork-type quartz crystal resonators lying in the first guide groove slide into the second guide groove and transition from an inclined arrangement state to a vertical arrangement state.

[0063] See Figure 4 The longitudinal section of the first guide groove is U-shaped, with a smaller top and a larger bottom. From the first guide groove 307 to the feeding guide rail, the second guide groove 308 transitions from an inclined state to a vertical state. This structure of the second guide groove facilitates the smooth entry of the tuning fork-type quartz crystal resonator from the first guide groove into the second guide groove, and the tuning fork-type quartz crystal resonator is not easily damaged.

[0064] See also Figure 1 , Figures 5-7 The feeding guide rail includes a feeding connecting guide rail 303, a feeding circular guide rail 304, and a feeding straight guide rail 305 connected in sequence. Each of the feeding connecting guide rail 303, the feeding circular guide rail 304, and the feeding vertical guide rail 305 is provided with a third guide groove that communicates with each other. The third guide groove communicates with the second guide groove 308 of the vibratory feeder. The third guide groove of the feeding connecting guide rail 303 is vertically arranged. (See reference...) Figure 5 The third guide groove of the feeding annular guide rail 304 is arc-shaped, and the third guide groove of the feeding straight guide rail 305 is slightly inclined.

[0065] See also Figure 5 and Figure 6 The angle between the inclination direction of the feeding straight guide rail 305 and the vertical direction is α, where 0 < α < 20°; preferably, 0 < α < 15°, and even more preferably, 5 < α < 10°.

[0066] See Figure 6 and Figure 7The feeding guide rail 305 is set at a slight inclination, and there is a gap between the feeding guide rail and the bottom plate assembly below. When the tuning fork type quartz crystal resonator 4 is discharged from the feeding guide rail, the pins of the tuning fork type quartz crystal resonator 4 first contact the bottom plate assembly, and the outer shell at the base position finally falls steadily at the notch 202 position on the bottom plate assembly 2.

[0067] See also Figure 1 and Figure 2 The automatic arrangement equipment also includes a feeding guide rail vibration seat 306, which acts on the feeding guide rail. Specifically, the feeding guide rail vibration seat 306 acts on the feeding straight guide rail 305. Under the vibration of the feeding guide rail vibration seat 306, the tuning fork type quartz crystal resonator located at the feeding straight guide rail 305 can be smoothly discharged.

[0068] See also Figures 8 to 13 The automatic foot expansion device includes a pressure block 515, a pressure block driving mechanism, a pin assembly containing a plurality of pins 509 arranged side by side, and a pin driving mechanism. The pins 509 are conical and vertically arranged. The pressure block driving mechanism drives the pressure block 515 to move up and down, and the pin driving mechanism drives the pin assembly to move up and down. When the pin moves downward, it passes through the first cylindrical hole 203 on the base plate assembly.

[0069] After passing through the automatic arrangement device, tuning fork-type quartz crystal resonators are arranged at equal intervals on the base plate assembly 2. The outer shell of the tuning fork-type quartz crystal resonator base is limited by the equally spaced notches 202 on the base plate assembly 2. The two pins extend toward the first cylindrical hole 203 and are located in the middle of the first cylindrical hole 203. The pressure block 515 presses down to fix the base plate assembly 2 located below. When the pin 509 moves downward, it passes through the two pins and enters the first cylindrical hole 203 on the base plate assembly, thereby expanding the distance between the two pins.

[0070] See also Figures 8-10The pressing block driving mechanism includes a first driving cylinder 501, a first driving cylinder fixing block 502, two first guide posts 503, a pressing block connector 514, and two pressing block limiting members 504 for limiting the downward movement distance of the pressing block. The first end of the pressing block connector 514 is connected to the output end of the first driving cylinder 501 and sleeved on the first guide post 503. The pressing block limiting member 504 is connected to the second end of the pressing block connector 514 via an adapter block 505, and the pressing block 515 is connected to the second end of the pressing block connector 514 via the adapter block 505. The pressing block limiting member 504 is provided to prevent the pressing block from excessively moving downwards and damaging the tuning fork-type quartz crystal resonator placed on the base plate assembly.

[0071] See Figure 8 and Figure 9 It is also equipped with a collision protection block 12, a guide pin 508, and a pin positioning hole 513. The collision protection block 12 plays a buffering role against the impact of the pressure block limiting member 504.

[0072] The height of the pressure block limiting member 504 is adjustable. The height of the pressure block limiting member is adjusted according to the different heights of the base plate assembly 2, thereby controlling the extreme position of the downward movement of the pressure block. Specifically, the pressure block limiting member 504 can be adjusted by threads.

[0073] See also Figures 8-10 The pin drive mechanism includes a second drive cylinder 511, two second guide posts 510, a pin connecting block 506, and a pin connecting plate 507. The second drive cylinder 511 is fixed above the pressure block connector 514, and the second guide posts 510 are fixed below the pressure block connector 514. The first end of the pin connecting block 506 is connected to the output end of the second drive cylinder and is sleeved on the second guide post 510. The second end of the pin connecting block 506 is connected to the pin connecting plate 507, and the pin assembly is connected below the pin connecting plate.

[0074] See Figure 13 The base plate assembly 2 includes a crystal oscillator connecting plate 201, which is closely attached to the upper surface of the base plate assembly. The crystal oscillator connecting plate is provided with a second cylindrical hole concentric with the first cylindrical hole.

[0075] See also Figures 8-12This application also includes a fixing mechanism for fixing the tuning fork type quartz crystal resonator to the crystal oscillator connecting plate. The fixing mechanism includes a roller 6 wound with tape, a rolling mechanism 7 for rolling the tape, a limiting member 703 for limiting the movement distance of the rolling mechanism, and a rolling mechanism guide 8 arranged parallel to the base plate assembly. The rolling mechanism 7 moves along the rolling mechanism guide 8. The rolling mechanism 7 includes a rolling mechanism connecting block, two sets of coaxially connected rolling gears 701 located on both sides of the rolling mechanism connecting block, and a limiting disk 702 coaxially connected to the rolling gears. The rolling mechanism guide 8 includes a rack meshing with the rolling gears and a limiting groove 801 matching the limiting disk. The limiting groove 801 is arranged along the rolling mechanism guide 8.

[0076] The rolling gear on one side of the rolling mechanism rolls with the rack, while the rolling gear on the other side rolls on the crystal oscillator connecting plate to roll the tape.
