Detailed Implementation

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0036] like Figure 1 As shown, in the current crystal oscillator manufacturing process, the crystal oscillator base 10 needs to be assembled with the PCBA board 20. Each crystal oscillator base 10 has four pins 101. When the pins 101 of the crystal oscillator base 10 are tilted or bent, they need to be manually corrected with tweezers before being inserted into the corresponding holes in the PCBA board 20. This manual correction method is inefficient and has poor consistency, which can easily affect the product performance of the crystal oscillator.

[0037] To address the aforementioned issues, this embodiment provides a pin calibration device that improves the consistency of pin 101 after calibration, facilitates assembly with PCBA board 20, enhances the performance of the crystal oscillator, and increases production efficiency.

[0038] Specifically, such as Figure 2 As shown, the pin 101 calibration device includes a base 1, a support platform 2, and a clamping mechanism 3. The support platform 2 is disposed on the base 1 and is used to place the crystal oscillator base 10. The clamping mechanism 3 includes a first driving component 31, a second driving component 32, and two grippers 33. The first driving component 31 is disposed on the base 1, and the second driving component 32 is disposed at the output end of the first driving component 31. The first driving component 31 is used to drive the second driving component 32 to move the grippers 33 along a first direction. The second driving component 32 is used to drive the two grippers 33 to move closer to each other in a second direction, so that the two grippers 33 jointly clamp the pin 101 on the crystal oscillator base 10. The first direction is perpendicular to the second direction. For ease of understanding, in this embodiment, the first direction is defined as... Figure 2 The X-axis direction, the second direction is Figure 2 The Y-axis direction in the diagram.

[0039] In use, the crystal oscillator base 10 is first placed on the support platform 2. Then, the first drive component 31 drives the second drive component 32 to move along the X-axis. The second drive component 32 drives the two grippers 33 to move along the X-axis, so that the grippers 33 are close to the pin 101. While approaching the pin 101, the second drive component 32 drives the two grippers 33 to move closer to each other in the second direction, so that the two grippers 33 jointly clamp the pin 101 on the crystal oscillator base 10. Thus, the clamping action corrects the tilted or bent pin 101, realizes automated correction, improves production efficiency, and can improve the consistency of the pin 101 after correction, making it easier to assemble with the PCBA board 20, thereby improving the product performance of the crystal oscillator.

[0040] like Figure 2 As shown, in this embodiment, two clamping mechanisms 3 are configured, and the support platform 2 is located in the middle of the base 1. The two clamping mechanisms 3 are arranged at intervals in the first direction and are symmetrically arranged about the support platform 2. The two clamping mechanisms 3 perform correction simultaneously, which improves working efficiency.

[0041] Specifically, such as Figure 1 As shown, the first drive assembly 31 includes a drive member 311 and a mounting plate 312. The drive member 311 is disposed on the base 1, and the mounting plate 312 is connected to the output shaft of the drive member 311. The second drive assembly 32 is disposed on the mounting plate 312. The drive member 311 can drive the mounting plate 312 to move along the first direction, thereby driving the second drive assembly 32 to move along the first direction. In this embodiment, the drive member 311 can be a cylinder, which has a compact structure, light weight, and small space occupation. In other optional embodiments, the drive member 311 can also be a linear motor or other drive structures capable of linear movement.

[0042] In this embodiment, a floating connection is used between the output shaft of the drive component 311 and the mounting plate 312. Specifically, as shown... Figure 3As shown, an adapter 313 is connected to the output shaft of the drive member 311. The adapter 313 includes a large-diameter section 3131 and a small-diameter section 3132. A step 3133 is formed at the junction of the large-diameter section 3131 and the small-diameter section 3132. A connecting groove 3121 is provided on the mounting plate 312. The connecting groove 3121 includes a second groove 31212 and a first groove 31211 connected to each other from the side near the drive member 311. The size of the first groove 31211 in the second direction is larger than the size of the second groove 31212. The large-diameter section 3131 is located in the first groove 31211, and the small-diameter section 3132 is located in the second groove 31212. The step 3133 can abut against the side wall of the first groove 31211. When the output shaft of the cylinder drives the adapter 313 to move in the first direction, the mounting plate 312 can be driven to move in the first direction through the cooperation of the large diameter section 3131 and the first groove 31211. This floating connection method can prevent over-positioning and cylinder jamming.

[0043] Combination Figure 2 and Figure 4 To achieve the clamping action of the two grippers 33, cam grooves 331 are respectively provided on the opposite sides of the two grippers 33. The second drive assembly 32 includes two follower components 321 that respectively cooperate with the corresponding cam grooves 331. The follower component 321 includes a connecting block 3211, a rotating shaft 3212 and a follower bearing 3213. The connecting block 3211 is connected to the output end of the first drive assembly 31. The rotating shaft 3212 is erected on the connecting block 3211. The follower bearing 3213 is rotatably mounted on the rotating shaft 3212. The follower bearing 3213 is located in the cam groove 331 and can cooperate with the side wall of the cam groove 331. When the two follower bearings 3213 drive the corresponding grippers 33 to move in the first direction, they can simultaneously drive the two grippers 33 to move closer to each other in the second direction.

[0044] When the first drive assembly 31 drives the two follower bearings 3213 to move along the positive X-axis, the follower bearings 3213 engage with the curved contour of the corresponding cam groove 331. This pushes the gripper 33 closer to the pin 101 along the X-axis, simultaneously driving the two grippers 33 to move closer together, so that the two grippers 33 jointly clamp the pin 101. This clamping action corrects any tilting or bending of the pin 101. In this way, the clamping action of the two grippers 33 can be achieved through one drive assembly 311 and two follower components 321, eliminating the need for a drive structure that drives along the second direction, thus saving costs and reducing the size of the device. Furthermore, the rolling friction between the follower bearings 3213 and the cam groove 331 reduces friction and extends the service life of the components.

[0045] In other alternative embodiments, the use of connecting block 3211 can be omitted, and the rotating shaft 3212 can be directly connected to the mounting plate 312.

[0046] Furthermore, such as Figure 2 As shown, multiple elastic reset elements 34 are connected between the two grippers 33. When the output shaft of the cylinder retracts, it drives the follower bearing 3213 to move along the positive X-axis. The follower bearing 3213 pushes the grippers 33 closer to the pin 101 along the positive X-axis, and at the same time drives the two grippers 33 to overcome the elastic force of the elastic reset elements 34 and move closer to each other, thereby clamping the pin 101 and achieving correction. After correction, the output shaft of the cylinder extends and drives the follower bearing 3213 to move along the negative X-axis. At the same time, under the action of the elastic reset elements 34, the two grippers 33 move away from each other and release the pin 101. Then the follower bearing 3213 drives the grippers 33 along the negative X-axis, so that the grippers 33 move away from the pin 101 and reset.

[0047] In this embodiment, the elastic reset element 34 is a spring. In other optional embodiments, the elastic reset element 34 can also be a reset spring or other elastic element with a reset function.

[0048] Furthermore, such as Figure 2 and Figure 5 As shown, two grippers 33 are defined as the first gripper 332 and the second gripper 333, respectively. The end of the first gripper 332 has two first clamping portions 3321 spaced apart along a second direction, and the end of the second gripper 333 has two second clamping portions 3331 spaced apart along a second direction. The first clamping portions 3321 and the second clamping portions 3331 are arranged in a one-to-one correspondence. Each first clamping portion 3321 and the corresponding second clamping portion 3331 are used to clamp one pin 101. In this way, each clamping mechanism 3 can simultaneously realize the clamping and correction of two pins 101, and two opposing clamping mechanisms 3 can simultaneously realize the correction of four pins 101. Therefore, the correction of four pins 101 on a crystal oscillator base 10 can be completed at one time, which greatly improves the working efficiency.

[0049] like Figure 2 and Figure 6 As shown, the clamping mechanism 3 also includes a first guide assembly 35, which includes a first guide rail 351 and a first slider 352. The first guide rail 351 is disposed on the base 1 and extends along a first direction. The first slider 352 is connected to the bottom of the mounting plate 312 and slidably connected to the first guide rail 351. The first guide assembly 35 can guide the mounting plate 312 along the X-axis direction, making the movement of the mounting plate 312 smoother and more stable.

[0050] In this embodiment, two first guide components 35 are provided, and the two first guide components 35 are arranged at intervals along the Y-axis to provide a stable guiding effect. In other optional embodiments, the first guide components 35 can also be one, three or more, depending on the actual needs, and no specific limitation is made here.

[0051] Furthermore, such as Figure 6 As shown, the clamping mechanism 3 also includes a second guide assembly 36, which includes a second guide rail 361 and two second sliders 362. The second guide rail 361 extends along a second direction, and the two second sliders 362 are respectively connected to the bottom of the corresponding gripper 33 and are slidably connected to the second guide rail 361. The second guide assembly 36 can guide the two grippers 33 along the Y-axis direction, making the movement of the grippers 33 along the Y-axis direction smoother and more stable.

[0052] like Figure 6 As shown, the clamping mechanism 3 also includes a third guide component 37, which is located between the two first guide components 35 to avoid interference. The third guide component 37 includes a third guide rail 371, a third slider 372, and a connecting plate 373. The third guide rail 371 is disposed on the base 1 and extends along the first direction. The third slider 372 is connected to the bottom of the connecting plate 373 and slidably connected to the third guide rail 371. The second guide rail 361 is connected to the connecting plate 373. The third guide component 37 can guide the gripper 33 along the X-axis direction, making the movement of the gripper 33 along the X-axis direction smoother and more stable.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
