[0041] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0042] In this application, the terms "upper" and "lower" and other terms indicating positions or locations are based on the positions or locations shown in the accompanying drawings. These terms are primarily intended to better describe this application and its embodiments and are not intended to limit the devices, elements, or components indicated to having a specific orientation, or to being constructed or operated in a specific orientation.

[0043] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to indicate a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0044] Furthermore, the terms "installed," "disposed," "equipped with," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0045] Furthermore, the terms "first," "second," etc., are primarily used to distinguish between different devices, elements, or components (which may or may not be of the same type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0046] In the related art, the lens module includes a lens body and a circuit board. During the production process of the lens module, it is usually necessary to test the firmness of the fixation of the lens body in the lens module on the circuit board. During the test, the circuit board of the lens module is usually fixed, and then a protective cap is put on the lens body. Finally, a tensile testing device is used to clamp the protective cap and pull the lens body to perform a tensile test on the lens module. However, the clamping effect of the existing tensile testing jig for clamping the circuit board is poor, and it can generally only be adapted to circuit boards of lens modules of a single specification. For circuit boards of lens modules of different specifications, it is usually necessary to replace jigs of different specifications for clamping. Therefore, the existing tensile testing jig not only has a poor clamping effect but is also difficult to adapt to lens modules of different specifications.

[0047] Based on this, the present application discloses a tensile test jig, which uses two different adjustment mechanisms to adjust the depth and length of the clamping space of the tensile test jig, so that it can clamp lens modules of different specifications. Moreover, during the clamping process, the clamping force of the clamping component on the lens module can be fine-tuned to facilitate the tensile test jig to improve the clamping effect of the lens module. In addition, multiple rulers are provided on the tensile test jig so that the size of the lens module can be measured again while the tensile test is being performed on the lens module, thereby improving the accuracy of the lens module size measurement.

[0048] The technical solution of the present application will be further described below with reference to the embodiments and drawings.

[0049] See Figure 1 and Figure 2The present application discloses a tensile testing fixture 100, comprising a base 1, a first positioning member 2 and a first adjustment mechanism 3. The first positioning member 2 is provided on the first mounting surface 1a of the base 1. The first adjustment mechanism 3 comprises a first clamping assembly 31 and a first adjustment assembly 32, and the first adjustment assembly 32 is movably provided on the first mounting surface 1a. The first clamping assembly 31 comprises a clamping part 311, and the clamping part 311 and the first positioning member 2 are arranged facing each other along the first direction X, so that a clamping space 1b is formed between the clamping part 311 and the first positioning member 2, and the clamping space 1b is configured to clamp the product to be tested. The first adjustment assembly 32 is connected to the first clamping assembly 31, and the first adjustment assembly 32 is configured to adjust the moving position of the first clamping assembly 31 along the first direction X to adjust the distance between the clamping part 311 and the first positioning member 2.

[0050] The tensile test fixture 100 disclosed in the present application uses a first adjustment mechanism 3 to adjust the length of its clamping space 1b for placing the product to be tested in the first direction X. For example, the first adjustment component 32 drives the clamping part 311 connected to it along the first direction X, and changes the size of the clamping space 1b by adjusting the distance between the clamping part 311 and the first positioning member 2. In this way, the clamping space 1b can accommodate products to be tested of different specifications, making the tensile test fixture 100 more applicable to different products. Moreover, in actual production, the time for replacing the test fixture when testing products of different specifications is reduced, which is conducive to improving production efficiency.

[0051] It is understandable that the products to be tested mentioned above may be electronic devices such as lens modules and speaker modules, or electronic components such as resistors, capacitors, inductors, sensors, etc. that have welding strength requirements on circuit boards. This application does not make specific limitations here.

[0052] It should be noted that in Figure 1 In the example shown, the direction indicated by X is the first direction X, and the first direction X may be the length direction or the width direction of the base 1 or the product to be tested.

[0053] Optionally, the clamping member 311 and the first positioning member 2 may be, but are not limited to, hard flat plates or hard blocks. The relatively flat side of the clamping member 311 is oriented toward the relatively flat side of the first positioning member 2 along the first direction X to clamp the product to be tested. This allows the clamping member 311 and the first positioning member 2 to clamp the product to be tested stably within the clamping space 1b, allowing it to be better aligned with the tensile testing equipment during testing.

[0054] In order to enable the clamping component 311 to better move with the first adjustment component 32 and effectively clamp the product to be tested, see Figure 3 and Figure 4 In some embodiments, the first clamping assembly 31 further includes a first movable seat 312, which is movably disposed on the first mounting surface 1a and connected to the first adjustment assembly 32 so that the first adjustment assembly 32 drives the first movable seat 312 to move along the first direction X. Furthermore, the clamping component 311 is movably disposed on the first movable seat 312 along the first direction X. Specifically, the first movable seat 312 is placed on the first mounting surface 1a, the clamping component 311 is placed on the first movable seat 312, and the first adjustment assembly 32 is connected to the first movable seat 312 along the first direction X. For example, during adjustment, the first adjustment assembly 32 can be adjusted to cause the first movable seat 312 to move along the first direction X, thereby adjusting the position of the clamping component 311 on the first movable seat 312. During the clamping process of the product to be tested, the first movable seat 312 only drives the clamping component 311 to move along the first direction X, so that the clamping component 311 and the first positioning member 2 can clamp the product to be tested along the first direction X. That is, during the adjustment process, the present application can first perform a preliminary adjustment of the position of the clamping member 311 via the first movable seat 312, and then adjust the position of the clamping member 311 on the first movable seat 312 to further adjust the position of the clamping member 311. In this way, the position of the clamping member 311 is effectively adjusted, achieving a secondary adjustment of the position of the clamping member 311, so that the clamping member 311 can more accurately clamp the product to be tested, so that the clamping space 1b formed by the clamping member 311 and the first positioning member 2 can better adapt to the product to be tested.

[0055] Optionally, the first clamping assembly 31 also includes an elastic member 313, a mounting seat 314 and a damping adjustment module 315. The mounting seat 314 is arranged on the first movable seat 312 and is located behind the clamping component 311 along the first direction X. The elastic member 313 is connected between the mounting seat 314 and the clamping component 311. The damping adjustment module 315 is installed on the mounting seat 314. The damping adjustment module 315 is connected to the elastic member 313. The damping adjustment module 315 is configured to adjust the damping of the elastic member 313 to adjust the clamping force of the clamping component 311 on the product to be tested.

[0056] In the first aspect, illustratively, along the first direction X, a clamping component 311, an elastic component 313, and a mounting seat 314 are sequentially arranged on the first movable seat 312, and a damping adjustment module 315 is disposed on the mounting seat 314. The two ends of the elastic component 313 are respectively connected to the clamping component 311 and the mounting seat 314, so that the clamping component 311 and the mounting seat 314 are spaced apart and the clamping component 311 can elastically float relative to the mounting seat 314. In this way, the elastic component 313 can generate active damping in the clamping component 311, so that the clamping component 311 can generate a relatively gentle clamping force when clamping the product to be tested. This allows the clamping component 311 to clamp the product to be tested more stably while also preventing the clamping component 311 from causing damage to the product to be tested due to excessive clamping force.

[0057] Secondly, the damping adjustment module 315, which is disposed on the mounting seat 314 and connected to the elastic member 313, can adjust the compression of the elastic member 313. That is, the damping adjustment module 315 can adjust the distance between the clamping member 311 and the mounting seat 314. When the distance between the clamping member 311 and the mounting seat 314 is smaller, the compression of the elastic member 313 is greater, the damping of the elastic member 313 on the clamping member 311 is greater, and the floating effect of the clamping member 311 relative to the mounting seat 314 is worse. When the distance between the clamping member 311 and the mounting seat 314 is larger, the compression of the elastic member 313 is smaller, the damping of the elastic member 313 on the clamping member 311 is smaller, and the floating effect of the clamping member 311 relative to the mounting seat 314 is better. For example, before clamping the product to be tested, the damping adjustment module 315 is adjusted according to the type of the product to be tested, thereby adjusting the damping of the elastic member 313, and then adjusting the clamping force of the clamping component 311 on the corresponding product to be tested, so that the clamping component 311 can better clamp the product to be tested.

[0058] It is understandable that the elastic member 313 can be a spring, elastic silicone, etc., and this application does not make any specific limitations here.

[0059] See Figure 5Optionally, the damping adjustment module 315 includes a slider 3151 and a threaded adjustment member 3152. The mounting base 314 has an installation space open to the elastic member 313. The slider 3151 is slidably disposed in the installation space and is connected to the elastic member 313. The mounting base 314 is provided with a first through-hole 314a extending along the first direction X and a second through-hole 314b extending along the thickness direction of the mounting base 314. The first through-hole 314a, the second through-hole 314b, and the installation space are all in communication. The threaded adjustment member 3152 includes a connected rod 315a and a head 315b. The rod 315a is located in the first through-hole 314a and connected to the slider 3151. The head 315b is at least partially disposed in the second through-hole 314b. The rod 315a is configured to drive the slider 3151 to slide within the installation space to adjust the damping of the elastic member 313. It is understood that due to the use of a threaded adjustment member 3152, the rod 315a of the threaded adjustment member 3152 located in the first through hole 314a is threadedly connected to the first through hole 314a. By twisting the head 315b of the threaded adjustment member 3152, the rod 315a can be moved within the first through hole 314a. The second through hole 314b provided on the mounting base 314 of the present application can be used to twist the head 315b of the threaded adjustment member 3152, and the first through hole 314a can be used to allow the twisted rod 315a to move. The rod 315a then drives the slider 3151 to move within the installation space. In this way, by adjusting the sliding position of the slider 3151 within the installation space, the compression or release of the elastic member 313 can be controlled to control the damping of the elastic member 313. In this way, during use, the technician can use his hands or tools to twist the head 315b of the threaded adjustment part 3152. The technician can accurately control the compression amount of the slider 3151 and the clamping part 311 on the elastic part 313 by the amount of twisting the head 315b, and then accurately control the clamping force of the clamping part 311 on the product to be tested, which is conducive to the smooth clamping of the product to be tested in the clamping space 1b.

[0060] Optionally, the threaded adjustment member 3152 may be, but is not limited to, a screw, a bolt, etc., and this application does not make any specific limitations here.

[0061] See Figure 6In some embodiments, a first scale 4 is provided on the first mounting surface 1a. The first scale 4 is located on one side of the clamping space 1b along the second direction Y, and the first scale 4 extends along the first direction X. Specifically, when the first adjustment assembly 32 adjusts the position of the first clamping assembly 31 along the first direction X, the first scale 4 can indicate the distance between the first clamping assembly 31 and the first positioning member 2 in the first direction X. In this way, when the clamping component 311 of the first clamping assembly 31 clamps the product to be tested, the distance between the first clamping assembly 31 and the first positioning member 2 in the first direction X is the length of the product to be tested in the first direction X. That is, the first scale 4 can indicate the length of the product to be tested in the first direction X, which facilitates the tensile testing fixture 100 to measure the dimensions of the product to be tested while clamping it.

[0062] In order to measure the size of the product to be tested more accurately, optionally, the first movable seat 312 has a second mounting surface 312a that is away from the first mounting surface 1a along its own thickness direction, the clamping component 311 is provided on the second mounting surface 312a, and the second mounting surface 312a is provided with a second ruler 5, the second ruler 5 is located on one side of the clamping component 311 along the second direction Y, and the second ruler 5 extends along the first direction X. For example, after the first ruler 4 is used to perform a preliminary measurement of the product to be tested, when the clamping component 311 clamps the product to be tested, the second ruler 5 located on one side of the clamping component 311 in the second direction Y can be used to perform further measurement, thereby measuring the more accurate size of the product to be tested. In this way, the present application can not only clamp products to be tested of different specifications, but also measure the sizes of products to be tested of different specifications more accurately.

[0063] Considering the smooth movement of the first movable seat 312 when it moves on the base 1, please refer to Figure 5 and Figure 6In some embodiments, a slide groove 6 is provided along the thickness direction of the first mounting surface 1a, extending along the first direction X and corresponding to the first adjustment mechanism 3. The first clamping assembly 31 also includes a guide seat 316, which is connected to the first movable seat 312 and is located in the slide groove 6. The slide groove 6 has a limiting portion 6a at the opening, which is configured to limit the guide seat 316 from leaving the slide groove 6. When the first movable seat 312 of the present application moves on the first mounting surface 1a, it slides on the first mounting surface 1a along the first direction X. If the first movable seat 312 simply slides in surface-to-surface contact with the first mounting surface 1a, when the adjustment force applied by the first adjustment assembly 32 to the first movable seat 312 is uneven, the sliding direction of the first movable seat 312 may deviate from the first direction X. To address this issue, the present application provides a slide groove 6 on the first mounting surface 1a and sets a guide seat 316 on the first movable seat 312. Exemplarily, when the first movable seat 312 slides along the first direction X, the guide seat 316 slides along the first direction X in the slide groove 6, and the sliding direction of the guide seat 316 is guided by the slide groove 6, thereby limiting the first movable seat 312 from sliding along the first direction X, which is beneficial to prevent the first movable seat 312 from deviating from the first direction X when sliding along the first direction X, so that the first movable seat 312 can slide stably toward the first positioning member 2.

[0064] Optionally, the limiting portion 6a can be a stopper provided at the opening of the chute 6 or can be a stopper integral with the base 1. The present application can prevent the guide seat 316 and the first movable seat 312 from leaving the chute 6 along the thickness direction of the base 1 by providing the limiting portion 6a at the opening of the chute 6, thereby limiting the position of the guide seat 316 within the chute 6.

[0065] It should be noted that in Figure 6 In the example shown, the direction indicated by Y is the thickness direction, which can be the thickness direction of the mounting base 314, the thickness direction of the base 1, etc. The thickness directions described in this application are all the directions indicated by Y. The direction indicated by Z is the second direction Y. For example, the second direction Y intersects with the first direction X. When the first direction X is the length direction of the base 1, the second direction Y can be the width direction of the base 1.

[0066] In some embodiments, the first adjustment assembly 32 includes a first fixing seat 321 and a first adjustment member 322. The first fixing seat 321 is disposed on the first mounting surface 1a. Along the first direction X, the first positioning member 2, the clamping member 311, and the first fixing seat 321 are sequentially spaced apart. The first adjustment member 322 is disposed on the first fixing seat 321 and is connected to the first clamping assembly 31. The first adjustment member 322 is configured to adjust the movement position of the first clamping assembly 31 along the first direction X. Exemplarily, the first adjusting component 32 is fixed to the first mounting surface 1a of the base 1 through the first fixing seat 321, and the first adjusting member 322 is passed through the first fixing seat 321 along the first direction X. The first fixing seat 321 limits the movement of the first adjusting member 322 along the first direction X, and then the first adjusting member 322 is connected to the first movable seat 312 of the first clamping component 31. The first adjusting member 322 can move relative to the first fixing seat 321 along the first direction X to drive the first movable seat 312 to move, so that the first adjusting member 322 adjusts the position of the first clamping component 31 on the first mounting surface 1a to achieve coarse adjustment of the position of the clamping component 311 in the first direction X.

[0067] Optionally, the first adjusting member 322 may be a screw, a pull rod, etc., which is not specifically limited in this application.

[0068] To further adjust the size of the clamping space 1b, see Figure 7 In some embodiments, the tensile testing fixture 100 further includes a second adjustment mechanism 7, which includes a second clamping assembly 71 and a second adjustment assembly 72. The second clamping assembly 71 is disposed in the clamping space 1b, and the second adjustment assembly 72 is connected to the second clamping assembly 71. The second adjustment assembly 72 is located on the side of the base 1 away from the first mounting surface 1a. The second adjustment assembly 72 is configured to drive the second clamping assembly 71 to move along the third direction Z in the clamping space 1b. The present application utilizes the second adjustment mechanism 7 to further adjust the size of the clamping space 1b. In one example, the second adjustment assembly 72 drives the second clamping assembly 71 to move along the third direction Z, and then cooperates with the first adjustment assembly 32 to drive the first clamping assembly 31 to move along the first direction X, so as to simultaneously adjust the size of the clamping space 1b in the first direction X and the third direction Z. In another example, when the clamping member 311 and the first positioning member 2 clamp the product to be tested, the second adjustment assembly 72 drives the second clamping assembly 71 to move along the third direction Z, thereby independently adjusting the size of the clamping space 1b in the third direction Z. In other words, the tensile testing jig 100 disclosed in this application can adjust the clamping space 1b in more dimensions, making it suitable for testing products of various specifications.

[0069] Considering that the second adjustment assembly 72 may push the second clamping assembly 71 out of the clamping space 1b when driving the second clamping assembly 71 to move, the second clamping assembly 71 optionally includes a second movable seat 711 and a second positioning member 712. The second movable seat 711 is located at the bottom of the clamping space 1b to support the product to be tested. The second positioning member 712 is located on one side of the clamping space 1b along the second direction Y and is connected to the first positioning member 2. The second movable seat 711 is movably connected to the second positioning member 712. The second positioning member 712 is configured to limit the movement position of the second movable seat 711 along the third direction Z. The second adjustment assembly 72 includes a second fixed seat 721 and a second adjustment member 722. The second fixed seat 721 is installed on a side of the base 1 away from the first mounting surface 1a. The second adjustment member 722 is provided on the second fixed seat 721 and connected to the second movable seat 711. The second adjustment member 722 is configured to adjust the movement position of the second movable seat 711 along the third direction Z. In other words, when the size of the clamping space 1b is adjusted along the third direction Z, the second movable seat 711 is mainly driven to move along the third direction Z by the second adjusting member 722. In one example, after the second movable seat 711 moves upward for a certain distance along the third direction Z, the second positioning member 712 located above the second movable seat 711 along the third direction Z can limit the second movable seat 711 from continuing to move upward. In another example, after the second movable seat 711 moves upward for a certain distance along the third direction Z, the second fixed seat 721 can stop the second adjusting member 722 to limit the second adjusting member 722 from continuing to drive the second movable seat 711 to move along the third direction Z. In this way, by limiting the movable position of the second movable seat 711 in the clamping space 1b, the second movable seat 711 can be prevented from being pushed out of the clamping space 1b, thereby improving the stability of the tensile testing fixture 100.

[0070] Optionally, the second adjusting member 722 may be a screw, a pull rod, etc., which is not specifically limited in this application.

[0071] Optionally, the second positioning member 712 may be, but is not limited to, a baffle, a block, etc., and this application does not make any specific limitation here.

[0072] It should be noted that in Figure 7 In the example, the direction indicated by Z is the third direction Z, which intersects the first direction X and the second direction Y respectively. The third direction Z may also be the thickness direction of the base 1 .

[0073] Since the size of the clamping space 1b in the third direction Z is adjustable, this application also considers that the size of the product to be tested can be measured when the product to be tested is clamped in the third direction Z. Please refer to Figure 6 and Figure 7Optionally, the first positioning member 2 has a first surface 2a and a second surface 2b along the second direction Y. The second positioning member 712 is connected to the first surface 2a so that the first positioning member 2, the second positioning member 712, the first movable seat 312 and the second movable seat 711 form a clamping space 1b. The second surface 2b is provided with a third scale 8, and the third scale 8 extends along the third direction Z. Specifically, since the first positioning member 2 forms the clamping space 1b, the second surface 2b is adjacent to the clamping space 1b, and the third scale 8 provided on the second surface 2b is also adjacent to the clamping space 1b. When the product to be tested is clamped in the clamping space 1b, the third scale 8 extending along the third direction Z can correspond to the size of the product to be tested in the third direction Z. For example, when the product to be tested is clamped in the clamping space 1b, the first ruler 4 located on the first mounting surface 1a, the second ruler 5 located on the second mounting surface 312a, and the third ruler 8 located on the second surface 2b can simultaneously measure the dimensions of the product to be tested in the first direction X and the third direction Z, which is conducive to obtaining more accurate dimensional data of the product to be tested for subsequent production use.
