Description
Technical Field
[0001] This application relates to the field of keyboard key core testing equipment, and more particularly to a keyboard key core testing fixture. Background Technology
[0002] Keyboard keycap testing fixtures are specialized devices used for testing and calibrating keyboard keycaps, primarily in the production, repair, and quality control stages of keyboard keycap manufacturing. During testing, the keycap is first fixed to the fixture, and then the pin connectors on the fixture are connected to the pin connections on the keycap. A specialized testing procedure is then used to power on and test the keycap. Because keyboard keycap manufacturers typically need to produce multiple sizes of keycaps simultaneously to meet market demands, or because the same keycap size may need to be adjusted to accommodate different product models, the control board of the keycap may require repositioning to adapt to the different product boards.
[0003] However, current keyboard keycap testing fixtures are typically developed and designed for a single keyboard keycap model. Multiple keycap models require different testing fixtures, which significantly increases production costs and impacts production line efficiency.
[0004] Therefore, the aforementioned technical defects urgently need to be addressed. Utility Model Content
[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a keyboard key core testing fixture, which is designed to adapt to keyboard key cores of different sizes and models, and improve the flexibility of the keyboard key core testing fixture.
[0006] The technical solution adopted by this application to solve the technical problem is as follows: A keyboard key core testing fixture, comprising:
[0007] The main body base has a support platform on it, which is used to support and fix the key core of the keyboard to be tested. A slide rail is provided on one side of the support platform, and the slide rail extends along the first direction.
[0008] At least two clamping mechanisms are slidably connected to the slide rail in sequence. A ribbon cable connection platform is provided on the side of the clamping mechanism near the support platform. The ribbon cable connection platform is used to position and support the ribbon cable connector of the keyboard key core to be tested.
[0009] And a limiting mechanism, which is used to abut against the side wall of the key core of the keyboard to be tested. The limiting mechanism can slide and adjust along the X-axis and Y-axis of the support platform.
[0010] The fixture mechanism is equipped with a lifting platform that moves up and down vertically along the cable connection platform. The lifting platform is equipped with a pin contact plate with several cable contact pins arranged on it. The cable contact pins are used to contact and connect to the cable connector of the keyboard key core to be tested.
[0011] In one possible implementation, the limiting mechanism includes an X-axis limiting member and a Y-axis limiting member, both of which are slidably connected to the support platform. The X-axis limiting member and the Y-axis limiting member extend along the X-axis direction and the Y-axis direction, respectively. The X-axis limiting member can slide along the Y-axis direction, and the Y-axis limiting member can slide along the X-axis direction. The X-axis limiting member and the Y-axis limiting member are used to abut against the side wall of the key core of the keyboard to be tested.
[0012] In one possible implementation, the support platform is provided with at least one first track groove, which extends along the X-axis direction, and the X-axis limiting member is slidably connected to the track groove.
[0013] In one possible implementation, the X-axis limiting member is provided with at least one second track groove, the second track groove extends along the Y-axis direction, and a limiting track is provided near the second track groove of the Y-axis limiting member. The limiting track matches the second track groove, and the Y-axis limiting member is slidably connected to the second track groove through the limiting track.
[0014] In one possible implementation, an abutment bolt is screwed onto the Y-axis limiting member. The abutment bolt passes through the screw hole on the Y-axis limiting member and abuts against the support platform, so that the Y-axis limiting member and the X-axis limiting member are fixed on the support platform. The screw hole extends vertically and passes through the Y-axis limiting member.
[0015] In one possible implementation, at least two through slots are provided on the slide rail, the through slots penetrate the base of the main body and extend along the extension direction of the slide rail, the clamping mechanism is provided with clamping pins at the positions corresponding to the through slots, the clamping pins penetrate the base of the main body and the through slots, one end of the clamping pin is provided with an abutment part, the abutment part abuts against the clamping mechanism, and a clamping knob is screwed to the end of the clamping pin near the back of the base of the main body.
[0016] In one possible implementation, the clamping mechanism is provided with a telescopic component, one end of which is provided with a driving component for driving the telescopic component to extend and retract, and the other end of the telescopic component is connected to the lifting platform, which moves the lifting platform vertically.
[0017] In one possible implementation, the base of the main body is provided with at least one button for activating the driver.
[0018] In one possible implementation, the ribbon cable connection platform has an inner groove that matches the keyboard key core ribbon cable connector. The inner groove is used to accommodate the ribbon cable connector of the keyboard key core to be tested.
[0019] Compared with existing technologies, this application provides a keyboard key core testing fixture. Before testing the keyboard key core, the position of the limiting mechanism in the X and Y axes of the support platform needs to be adjusted, and the position of the lifting platform needs to be adjusted along the first direction to match the size of the keyboard key core model. During subsequent testing, the keyboard key core only needs to be placed on the pre-adjusted limiting points to achieve the positioning function. This can accommodate keyboard key cores of different sizes and models, improving the flexibility of the keyboard key core testing fixture. Attached Figure Description

[0028] Furthermore, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.
[0029] This utility model provides, for example Figure 1 , Figure 2 and Figure 3As shown, a keyboard key core testing fixture is used for testing and calibrating keyboard key cores during the production, repair, and quality control processes. When testing the keyboard key core, the key core is first fixed to the fixture, the keyboard key core's ribbon cable connector is connected, and then the pin connector on the fixture is connected to the pin connection end of the keyboard key core. The keyboard key core is then powered on and tested using a specialized testing procedure. The main structure includes: a base 1, at least two clamping mechanisms 2, and a limiting mechanism 3. The base 1 has a support platform 11 for supporting and fixing the keyboard key core to be tested. A slide rail 12 is provided on one side of the support platform 11, extending along a first direction. The two clamping mechanisms 2 are slidably connected to the slide rail 12. In actual keyboard key core testing, the number of clamping mechanisms 2 can be matched according to the number of ribbon cable connectors of the keyboard key core to be tested. A ribbon cable connection platform 21 is provided on the side of the clamping mechanism 2 near the support platform 11. The ribbon cable connection platform 21 is used to position and support the ribbon cable connector of the keyboard key core to be tested. The limiting mechanism 3 is used to abut against the side wall of the keyboard key core to be tested. The limiting mechanism 3 can slide and adjust along the X-axis and Y-axis directions of the support platform 11. The side of the limiting mechanism 3 abuts against the side of the keyboard key core to be tested, thereby positioning the keyboard key core and facilitating faster positioning of the keyboard key core ribbon cable connector. The first direction is as follows: Figure 1 As shown.
[0030] The fixture mechanism 2 is equipped with a lifting platform 22, which moves up and down in the vertical direction of the ribbon cable connection platform 21. The lifting platform 22 is equipped with a pin contact plate 221, and a number of ribbon cable contact pins 222 are arranged on the pin contact plate 221. The ribbon cable contact pins 222 are used to contact and connect the ribbon cable connector of the keyboard key core to be tested.
[0031] It should be noted that current keyboard keycap testing fixtures are typically developed and designed for a single keyboard keycap model. However, multiple keyboard keycap models require the development of different testing fixtures. This undoubtedly increases the production cost of the testing fixtures significantly and also affects the efficiency of production line adjustments.
[0032] Before testing the keyboard key core, this invention requires adjusting the position of the limiting mechanism 3 along the X and Y axes of the support platform 11, and adjusting the position of the lifting platform 22 along the first direction to match the size of the keyboard key core model. During subsequent testing, the keyboard key core is simply placed on the pre-adjusted limiting points to achieve the positioning function. This design can accommodate keyboard key cores of different sizes and models, improving the flexibility of the keyboard key core testing fixture.
[0033] Furthermore, the limiting mechanism 3 includes an X-axis limiting member 31 and a Y-axis limiting member 32, both of which are slidably connected to the support platform 11. The X-axis limiting member 31 and the Y-axis limiting member 32 extend along the X-axis and Y-axis directions respectively. The X-axis limiting member 31 can slide along the Y-axis direction, and the Y-axis limiting member 32 can slide along the X-axis direction. The X-axis limiting member 31 and the Y-axis limiting member 32 are used to abut against the sidewall of the key core of the keyboard being tested. The X-axis direction is parallel to the first direction.
[0034] Furthermore, such as Figure 1 As shown, the support platform 11 is provided with at least one first track groove 111, which extends along the X-axis direction. The X-axis limiting member 31 is slidably connected to the track groove. In some embodiments, the support platform 11 is provided with two first track grooves 111, and the X-axis limiting member 31 slides along the X-axis direction through the two first track grooves 111. The two first track grooves 111 can ensure that the X-axis limiting member 31 can slide smoothly on the support platform 11.
[0035] Furthermore, such as Figure 1 and Figure 2 As shown, the X-axis limiting member 31 is provided with at least one second track groove 311, which extends along the Y-axis direction. The Y-axis limiting member 32 is provided with a limiting track 321 near the second track groove 311. The limiting track 321 matches the second track groove 311, and the Y-axis limiting member 32 is slidably connected to the second track groove 311 through the limiting track 321.
[0036] Furthermore, such as Figure 1 and Figure 2 As shown, an abutment bolt 322 is screwed onto the Y-axis limiting member 32. The abutment bolt 322 passes through the screw hole 323 on the Y-axis limiting member 32 and abuts against the support platform 11, so that the Y-axis limiting member 32 and the X-axis limiting member 31 are fixed on the support platform 11. The screw hole 323 extends vertically and passes through the Y-axis limiting member 32.
[0037] It should be noted that when it is necessary to move the Y-axis limiter 32 and the X-axis limiter 31, unscrew the abutment bolt 322 to allow them to slide in the Y-axis and X-axis directions respectively, thus achieving the unlocking function. This allows staff to adjust the positions of the Y-axis limiter 32 and the X-axis limiter 31 according to the model and size of the keyboard key core. After adjusting the positions of the Y-axis limiter 32 and the X-axis limiter 31, tighten the abutment bolt 322 so that the end of the abutment bolt 322 abuts against the support platform 11, thereby fixing the Y-axis limiter 32 and the X-axis limiter 31 to the support platform 11 and achieving the locking function.
[0038] Furthermore, such as Figure 1As shown, the slide rail 12 has at least two through slots 121, which penetrate the base 1 and extend along the extension direction of the slide rail 12. The clamping mechanism 2 has clamping pins 122 corresponding to the positions of the through slots 121. The clamping pins 122 penetrate the base 1 and the through slots 121. One end of the clamping pin 122 has an abutment portion 1221 that abuts against the clamping mechanism 2. A clamping knob 1222 is screwed to the end of the clamping pin near the back of the base 1. Specifically, the two through slots 121 are arranged in parallel. It can be understood that the parallel arrangement of the two through slots 121 allows the clamping mechanism 2 sliding on the slide rail 12 to be subjected to balanced forces. When the clamping knob 1222 on the clamping pin 122 is released... Since the clamping mechanism 2 loses the clamping force of the clamping pin 122, it can slide freely along the extension direction of the slide rail 12, making it convenient for staff to adjust the position of the clamping mechanism 2 according to the model and size of the keyboard key core. After adjusting the position of the clamping mechanism 2, tighten the clamping knob 1222. The clamping mechanism 2 is then fixed to the base 1 of the main body by the clamping pin 122.
[0039] Furthermore, such as Figure 1 and Figure 3 As shown, the clamping mechanism 2 is provided with a telescopic member 23. One end of the telescopic member 23 is provided with a driving member 231, which is used to drive the telescopic member 23 to extend and retract. The other end of the telescopic member 23 is connected to the lifting platform 22, and the telescopic member 23 raises and lowers the lifting platform 22 in the vertical direction. Preferably, the driving member 231 is configured as an electric driving member 231 to drive the telescopic member 23 to extend and retract, so that the lifting platform 22 can realize the lifting function.
[0040] Furthermore, such as Figure 1 As shown, the base 1 of the main body is provided with at least one button 13, which is used to activate the drive unit 231. After the operator positions the keyboard key core on the support platform 11 and places the keyboard key core ribbon cable connector on the ribbon cable connection platform 21, pressing button 13 will lower the lifting platform 22 to a preset height, connecting the pin contact plate 221 and the keyboard key core ribbon cable connector to establish an electrical connection for subsequent keyboard key core function testing.
[0041] Furthermore, such as Figure 3 As shown, the ribbon cable connection platform 21 has an inner groove 211, which matches the keyboard key core ribbon cable connector. The inner groove 211 is used to accommodate the ribbon cable connector of the keyboard key core to be tested.
[0042] Understandably, the ribbon cable connection platform 21 uses the inner groove 211 to accommodate the ribbon cable connector of the keyboard key core to be tested, allowing the connector to be quickly positioned and installed on the platform 21. This improves the efficiency of keyboard key core installation and calibration. Furthermore, the inner groove 211 has an opening on the side near the keyboard key core to be tested, so that the connector of the keyboard key core ribbon cable can be directly installed and recessed into the bottom of the inner groove 211.
[0043] In summary, this application provides a keyboard key core testing fixture. Before testing the keyboard key core, the position of the limiting mechanism 3 in the X-axis and Y-axis directions of the support platform 11 needs to be adjusted, and the position of the lifting platform 22 needs to be adjusted along the first direction to match the size of the keyboard key core model. During subsequent testing, the keyboard key core only needs to be placed on the pre-adjusted limiting points to achieve the positioning function. This fixture can adapt to different sizes and models of keyboard key cores, improving its flexibility.
[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
